Total S.A. Company Essay Example | Topics and Well Written Essays - 2250 words
Total S.A. Company - Essay Example The companyââ¬â¢s upstream sector is seen to mainly consist of the companyââ¬â¢s vast exploration projects for the production of natural gas and crude oil; this is done alongside various gas and electricity developmental activities and coal mining operations. TOTALââ¬â¢s downstream unit is seen to mainly focus on trading of petroleum products, their marketing as well as refining operations while its chemical division is seen to include the production of various rubber products that are made by its Hutchinson subsidiary. The bulk of the rubber products produced by this subsidiary are usually mostly targeted at the automotive industry. Other chemical products that the company produces include resins, adhesives, inks and paints (Reuters, 2013). When the company was initially formed in 1924 after the first world war, it was initially named as compagnie Françse des Pà ©troles. At the time of its formation , the French government considered the company as being of critical strategic importance in the event that there happened to be another war with Germany. After the war, the French secured a 25 percent stake in the by then fledgling Turkish Petroleum company whose shares were mostly held by Germanyââ¬â¢s Deutsche Bank. ... He incorporated some parts of Orkem chemical group into Totalââ¬â¢s various chemical operations. The chemical division was responsible for the production of resins, inks, paints and adhesives. At the time of his taking over the companyââ¬â¢s chairmanship, Total company had slowly turned into a complexly organized, extremely bureaucratic and sleepy company and as a result, the company had inadvertently ceded its coveted position of being Franceââ¬â¢s largest oil company to its rival Elf Aquitaine. Serge managed to turn the company into an aggressive, more modern and sleeker company by abolishing and estimated over two hundred Total company subsidiaries as well as closing down about one-seventh of all of the companyââ¬â¢s service stations network (company-Histories.com, 2013), this effectively resulted in the elimination of about 6.500 jobs and saved the oil company hundreds of millions of francs in various expenses. The company also formulated new strategies that helped it defocus its production form the more unstable Middle East and aimed to shift about 50 percent of all its production to areas outside the Middle East. By 1995, the insistence of Tchuruk on ensuring that the company ensured that it beefed up its gas business was instrumental in causing the company to become the worldââ¬â¢s third largest gas producer (company-Histories.com, 2013). The companyââ¬â¢s name was later changed to Total in the year 1991 when company became listed as a public company and commenced trading on the New Stock Exchange. Tchuruk played a critical role in convincing the French government to ensure that it reduced its direct share holding investment in the oil to 5.4% which was an important move that helped the company increase its own independence as well as its ability to act

The Saudi Arabia General Investment Authority Essay Example for Free
The Saudi Arabia General Investment Authority Essay 1. How would you measure SAGIAââ¬â¢simpacton Saudi Arabiaââ¬â¢s competitiveness? Compare the improvement in indicators (number of days to register a business, FDI growth, employments indicators, etc.) between 2005 and 2011by referringto the Global Competitiveness Report, Doing Business Report and other sources. 2. What are the characteristics of effective networked governance? What are the advantages? What are the indications that SAGIA introduced networked governance? 3. What are One-Stop-Shops? How they may improve the business environment? What are the challenges of establishing them? One-Stop-Shops, also called Investor Service Centers (ISCs), inspired by the notion of a single site offering multiple services to investors and was refined further to eliminate passing through many offices around the building of each government agency to get the investorââ¬â¢s paper stamped. The one-stop shop includes a front desk and a back office; front desk has four to five customer relations managers, who professionally take all requirements and hand them to the back office which includes representatives from several government departments as well as international technologies and firms. This work Design helped SAGIA ensure high quality customer service and eliminate the potential for corruption while making procedures simpler and faster which reflected in greater firm satisfaction and savings with more businesses being registered, increased financial resources and job opportunities that utilizes the best available local resources. ISCs served as buffer zones, with the SAGIA customer service staff functioning as intermediaries between customers and government agency representatives. One of the challenges of establishing ISC, that it was staffed by government employees and the concern was that public service employees could not perform as well as their private counterparts, but this challenge was resolved by providing the right incentives to the staff by granting bonuses for incremental increases in the number of passports handled. The volume of passports handled was 100 times more than what was used to be handled with same amount of time. 4. What are the pros and cons of the Saudization Policy? What are its implications on the competitiveness of the Saudi Economy? Pros: * Replacing foreign workers with Saudis, since the Saudi economy is heavily dependent on them. * Lowering the Saudi unemployment rate. * Increase employment for Saudi nationals across all sectors of domestic economy. * Recapture and reinvest income which otherwise would have flowed overseas as remittances to foreign worker home countries. Cons: * Companies started to make fake mergers and acquisitions of its various divisions in order to meet their quota. * Saudis are being hired only because they are Saudi and not due to their qualifications. * Saudization caused Foreign and even Saudi companies to move their operations to UAE or other more business-friendly regional environments. * Thousands of low wage labors were forced to leave, such as shopkeepers and drivers, there are not always even enough Saudis who even want these job to replace them that resulted with replacing the good, skilled and cost effective labor with a national Saudi who lacks the interest, skill or experience in some cases to perform these jobs * Higher wage costs being imposed on organizations that discouraged investment in Saudi Arabia * Since the education system has largely failed to prepare the countryââ¬â¢s youth for jobs requiring technical expertise. Compounding this problem is that many graduates refuse to take assignments that are considered commonly as menial. Saudization clearly creates some disturbances, with some sectors like transport anticipating a catastrophe. The ultimate goal of development and hopefully higher growth comes with a cost in the form of short term transitional disruption. There are two main concerns. First, many firms may feel that Saudization will reduce their competitiveness and for that reason may decide to leave the kingdom for a more business friendly environment. These would most likely be firms in the service sectors such as banking. The countryââ¬â¢s poor regulatory environment only compounds this problem with a reportedly 2,500 Saudi companies opening up shops in Dubai, rather than in Saudi Arabia kingdom. The second main area of impact from Saudization may be a reduction of foreign direct investment (FDI) in the kingdom. Foreign firms may feel that Saudization not only puts them at a disadvantage compared to their foreign competitors, but that the whole Saudization program itself is unpredictable, with rules and quotas changing randomly. 5. Discuss the concept of Special Economic Zones and how they should be established to have maximum positive impact on the national economy and its competitiveness.

Biological Basis Of Behavior Essay -- Science Biology Biological Essay
Biological Basis Of Behavior Primary Behaviors of Schizophrenia Schizophrenia is defined as a "devastating psychotic disorder that may involve characteristic disturbances in thinking (delusions), perception (hallucinations), speech, emotions, and behavior (Durand and Barlow 443). This disorder affects nearly 2.5 million people. The symptoms of schizophrenia are usually divided into two categories, positive and negative. The positive symptoms include delusions, hallucinations, disorganized speech or thinking, grossly disorganized behavior, and catatonic behaviors, which means that you suffer from motor immobility (schizophrenia.com). Delusions are defined as a strong disorder of thought and false beliefs of reality. There are five categories of delusions. The first is persecutory in which a person believes they are being attacked, harassed or conspired against. For example, a person with persecutory delusions may think that the government is spying on them. The second category is grandiose delusions, which are defined as an exaggerated sense of importance, power, and identity. For example, a person may feel that they receive special powers from God which gives them the ability to control things. The third category is being controlled. This category of delusions involves thoughts and feelings imposed from the outside. This is sometimes referred to as "thought insertion." A person with this type of delusion may feel that they are being controlled by the devil or by a curse. The fourth category is somatic delusions. These are defined as having false beliefs about bodily functions such as having AIDS or being pregnant for three years. The last category is j... ... ended up in the psychiatric ward. He got on medicine but still felt like a "deer in the headlights." He had a hard time keeping up with school and then his medicine failed and he was hospitalized again. After the second hospitalization his life turned around. He ended up finishing school with a degree in Economics. He was also able to hold down several jobs. He has tried every atypical antipsychotic medicine and they seem to be working. People can overcome schizophrenia if they choose to and can succeed in their own way and beat the odds.

Training plan for employees
Recruitment, selection, training and evaluating employees Section A I have been hired by Laurent Bank of Canada, as a consultant to assist in hiring employees for the Commercial Banking Branch located In Montreal, Quebec. Laurent Bank Is a Quebec regional bank that has been In operation since 1846 and their head office Is located In downtown Montreal. The bank offers retail and commercial financial services. I will be consulting for the hilling of employees working at a new commercial branch located next to Concordia University, in Montreal.These employees will be working as Commercial Account Managers in the banking industry. The Laurent Bank Commercial Banking sector offers different types of loans for small business owners such as Credit Lines, Term Loans and Business VISAS. The Bank makes a profit by collecting the interest they have charged on each of their loans. The Bank is looking to hire 3 employees who have had previous experience working in the banking Industry as well as an educational background in Finance or Accounting, preferably at a University level (I. E. Bachelor's Degree).The newly hired employees will be responsible for managing a portfolio of existing business clients. They will also be required to bring In new clients to the Bank. Section B I will conduct the following job analysis to obtain Information on the skills, knowledge and ablest required for the Job: Identify and Isolate the component tasks Involved Examine how the tasks are performed Identify the main areas of responsibility Identify the working conditions I will use the 3 following methods to gather data from existing employees or sources to conduct my Job analysis: 1 .Interviewing existing Account Managers: I would meet with a few current employees working in Commercial Banking and ask them specific questions about their Job. 2. Perform an online search: I would search inline on Commercial Account Managers in order to gain knowledge on the field and specific requirements. 3. I would obtain access to the weekly activity logs: All Account Managers are required to submit a weekly actively log to their superiors. This log contains detailed Information on the work that was done during the week.Job Description: The Account Manager is responsible for structuring credits and addressing perceived risk. This includes completing necessary due diligence, establishing pricing and terms of credit, and also producing ongoing credit reviews and risk ratings that fleet knowledge of Bank policies and procedures. With respect to business development The Account Manager continually develops and broadens relationships with existing customers by cross-selling relevant and value added financial products and services. It is also a priority to build new relationships through referrals from customers and other sources.Section C I will recruit prospective employees by posting the Job description on Social Networking sites such as Linked and Faceable. I will also use job search we bsites also post the available position in the careers section of the corporate website of Laurent Bank. Social Networking sites are good way to attract Job seekers since almost everyone use Linked and Faceable. The majority of the population is using a smart phone nowadays with these applications already installed. Faceable would help me do a background check on applicants by having access to their network of friends, activities and hobbies.It would not, however give me much information on their education, skills or work experience. Linked is a more useful application for recruiters because its main use is to connect professionals through their work experience. Linked is an excellent calibration tool to help me assess the depth of the potential talent pool. The following 3 selections techniques will be used: I will compare the credentials from each candidate's profile or posted resume; I will personally message those who I have selected and inform them on my decision to pursue an i nterview; I will also perform background reference checks on the candidates.Comparing profiles between candidates will enable me to narrow down my search; however there is the possibility that I choose one candidate over another strictly based on the presentation of their online profile or resume. Sending a personal message to chosen candidates is good ways of letting the applicant know that we are interested. However, this method can also backfire when the applicant refuses to respond to the message in a timely manner, resulting in wastage of time. Background checks are always a good source for gaining insight on the applicant's past work experience.However, it is important to make sure you are speaking with the right person. It is not always easy to contact a candidate's previous boss due to availability. Old Boss' are not always eager to take the time out and speak about a past employee. Section D Once hired, the employees' performance will be evaluated on a weekly basis. The Men tor or personal in charge of training the employee will be required to fill out a performance form. The form will contain several sections about the different tasks required for the role of an Account Manager.The Mentor will grade each section with the following: A (achieved), F (failed), AN (non-applicable) and IP (in progress). This weekly evaluation will serve as an indicator of the employee's progress. It will also clearly indicate the areas where the employee needs improvement. The following training methods will be used: 1 . Job Shadowing with an existing Account Manager. This will enable the new employee to gain insight on the day-to-day activities of an account manager. It will also give the employee to ask questions on specific tasks.However, it can slow down the efficiency of Account Managers if they spend too much time answering questions. 2. Helping Account Managers with their portfolios. This will be both beneficial to the new and existing employees. New employees will gain experience by analyzing credit applications and financial statements. While the existing Account Manager will have more time work on other tasks and duties. However, the work submitted by the new employees will have to be revised by the Account Manager before submission. Section E The following 3 training programs will be used: 1 .Moody Analytics Account Manager. New employees will be required to complete the Commercial Lending program that involves online lessons on the specific skills needed for this role. Financial statement analysis, risk management and business development are the three topics covered in the lessons. After every lesson, employees are required to complete an examination testing their skills learned. The scores from these exams ill be sent directly to the Mentor. This will teach the employee on the three most important skills needed for an Account Manager.However, employees must be trusted to not consult other employees when answering the exam questions. 2. Financial Statement Analysis New employees will be given financial statements from new and existing clients to analyze. They will be required to calculate key ratios in order to determine the performance of the company in the current and past year. Financial statement analysis is a skill that must be mastered in order to be a successful Account Manager ND this is a good way to practice. The employee, however, might feel discouraged at first since all financial statements are different and can be very confusing at first. . Case Discussion New employees will be given the opportunity to discuss the risk associated with lending to the clients they have analyzed through financial statement analysis and job shadowing with an Account Manager. This will give a chance to new employees to express themselves and share their ideas. Some new employees, however, might feel too intimidated or shy to fully express their opinion. PART 2: Company Culture Section F I will advise leaders to help employ ees reach personal and organizational goals by pointing out the paths they should follow and by providing them with the means to do so.They would need to show concern and support for subordinates. The leader should use a transactional leadership style, where they can clearly identify the needs of their followers and give rewards in exchange for performance. They can set goals and expectations, reward effort and provide feedback. Section G Commercial Account Managers often work out of the office, visiting clients, checking out loan applications, and soliciting new business. Account Managers may be required to travel if a client is out of town, or to work evenings if that is the only time at which a client can meet.Employees in this role have the flexibility to work from home as well. Normal business banking hours are Monday to Friday from mamma to pm. An Account Manager manages his/her portfolio; therefore they usually manage least 37. 5 hours per week. Employees will be eligible for 4 weeks of vacation annually, however weeks must be reserved in advance to avoid too much vacancy at once. The office will be well located in central downtown Montreal. This will give employees the opportunity to take public transportation instead of driving their vehicles. It will also enable Account Managers to easily penetrate the commercial market.The office building will be connected to an underground metro station, which will facilitate travel during winter. All account managers will be provided with their own work space in the form of an open concept cubicle. This will encourage teamwork and also enable employees to interact with each other more frequently. There will be private rooms that can be reserved for client meetings. Upper Management will have private closed offices. There will also be a board room for meetings and presentations. The thermostat will be electronically adjusted to provide ideal temperatures for winter and summer.The lighting will be sufficient for des k work and each workstation will have its own computer, printer and telephone. There will also be a cafeteria open to all employees with a fridge and microwave. This will encourage employees to interact during lunch hour. I would be aware of the following psychological and social concerns: Job Autonomy and Harassment. I would assess the degree of satisfaction an employee has with their current role because it will be reflected in their reference. If the employee is not fully satisfied, they will feel exhausted with their role and eventually would not care to perform.This could eventually lead to the employee leaving their Job. Harassment is very serious and must be handled severely. Employees who face harassment might be too intimidated to report it. If it is not handled immediately, it can lead to serious lawsuits towards the organization. The policies on harassment will be clearly explained to all employees upon Joining the organization. Section H Stress in the workplace often coi ncides with the following behaviors in employees: rower productivity, reduced motivation, increased errors, and increased turnover.The role of an Account Manager often results in the following stresses: Role Overload. Employees feel there are too many tasks in too short time period. I would attempt to minimize stress using the following 3 programs: Improve communication 0 Share information with employees to reduce uncertainty about their Jobs and futures. Clearly define employees' roles and responsibilities. 0 Make communication friendly and efficient, not mean-spirited or petty. Consult Employees 0 Give workers opportunities to participate in decisions that affect their Jobs. Consult employees about scheduling and work rules. Be sure the workload is suitable to employees' abilities and resources; avoid unrealistic deadlines. 0 Show that individual workers are valued. 0 Offer rewards and incentives. As Employee of the Month. 0 Provide opportunities for career development. 0 Promote an ââ¬Å"entrepreneurialâ⬠work climate that gives employees more control over their work. Cultivate a friendly social climate 0 Provide opportunities for social interaction among employees. 0 Establish a zero- tolerance policy for harassment. 0 Make management actions consistent with organizational values.

Filtration & Centrifugation
FILTRATION ââ¬Å"Filtration may be defined as a process of separation of solids from a fluid by passing the same through a porous medium that retains the solids, but allows the fluid to pass through. â⬠The suspension to be filtered is known as slurry. The porous medium used to retain the solids is known as filter medium. The accumulated solids on the filter are referred to as filter cake, while the clear liquid passing through the filter is filtrate. When solids are present in a very low concentration i. e. , not exceeding 1. 0% w/v, the process of its separation from liquid is called ââ¬Ëclarificationââ¬â¢. Process of filtration: The filtration operation is shown below in the figure * The pores of the filter medium are smaller than the size of the particles to be separated. * Filter medium (for eg: filter paper or muslin cloth) is placed on a support (a sieve). * When slurry (feed) is passed over the filter medium, the fluid flows through the filter medium by virtue of a pressure differential across the filter. * Gravity is acting on the liquid column. Therefore, solids are trapped on the surface of the filter medium Figure 1: filtration Once the preliminary layer of particles is deposited, further filtration is brought about wherein the filter medium serves only as a support. * The filter will work efficiently only after an initial deposit. * After a particular point of time, the resistance offered by the filter cake is high that virtually filtration is stopped. For this reason, a positive pressure is applied on the filter cake (upstream) or negative pressure (suction) is applied below the filter medium (downstream). Factors affecting the rate of filtration: The rate of filtration which depends on various factors can be written as: Rate of filtration = Area of filter X Pressure difference Viscosity X Resistance of cake and filter The rate of filtration depends on the following factors: 1. Pressure: * The rate of filtration of liquid is directly proportional to the pressure difference between the ââ¬Ëfilter mediumââ¬â¢ and ââ¬Ëfilter cakeââ¬â¢. * Thus, the rate of filtration can be increased by applying pressure on the liquid being filtered or by decreasing the pressure beneath the filter. 2. Viscosity: * The rate of filtration is inversely proportional to the viscosity of the liquid undergoing filtration. Liquids which are very viscous get filtered slowly in comparison to liquids with low viscosity. * Reduction of viscosity of a liquid by raising the temperature is frequently done in order to accelerate filtration. eg: syrups are more quickly filtered when hot and cold. 3. Surface area of filter media: * The rate of filtratio n is directly proportional to the surface area of filter media. * Pleating the filter paper or using a fluted funnel increases the effective surface area of filter paper for filtration. Filter press also works on the same principle. 4. Temperature of liquid to be filtered: Temperature plays an important role in the rate of filtration. * Viscosity is reduced by a rise in temperature and the filtration of viscous oils, syrups etc is often accelerated by filtering them while they are still hot. 5. Particle size: * The rate of filtration is directly proportional to the particle size of the solid to be removed. * It is easier to filter a liquid having coarse particles than that having finely divided particles because coarse filtering medium can be used to filter liquid having coarse and hence it increases the rate of filtration. Therefore before filtration, some method should be adopted to agglomerate the finely divided particles into coarse particles or to increase the particle size by precipitation. 6. Pore size of filter media: * The rate of filtration is directly proportional to the pore size of the filter media. * The liquid having coarse particles requires a coarse filtering media to remove them. So, the rate of filtration is increased when a coarse filter medium is used for filtration. 7. Thickness of cake: * The rate of filtration is inversely proportional to the thickness of the filter cake formed during the process of filtration. As the filtration process proceeds, the solid particles start depositing on the filter medium, and thus, it increases the thickness of the cake and decreases the rate of filtration. 8. Nature of the solid material: * The rate of filtration is directly proportional to the porosity of the filter cake. * The porosity of the filter cake depends on the nature of the solid particles to be removed from the liquid. * Filter aids are sometimes added to the filtering liquid to make a porous cake Theories of filtration The flow of a liquid thorough a filter follows the basic rules that govern the flow of any liquid through the medium offering resistance. The rate of flow may be expressed as: Driving force Rate = ââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬â (equation 1) Resistance The rate of filtration may be expressed as volume (lit) per unit time (dv/dt). The driving force is the pressure differential between the upstream and downstream of the filter. The resistance is not constant. It increases with an increase in the deposition of solids on the filter medium. Therefore filtration is not a steady state. The rate of flow will be greatest at the beginning of the filtration process, since the resistance is minimum. Once the filter cake is formed, its surface acts as filter medium and solids continuously deposit adding to the thickness of the cake. The resistance to flow is related to several factors as mentioned below. Length of capillaries Resistance to movement = ââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬â Poiseuilleââ¬â¢s Equation: Poiseuilleââ¬â¢s considered that filtration is similar to the stream line flow of a liquid under pressure through capillaries. Poiseuilleââ¬â¢s equation is ? pr4 V = ââ¬âââ¬âââ¬âââ¬âââ¬âââ¬â 8L? Where, V= rate of flow, i. e. , volume of liquid flowing in unit time, m3/s(1/s) p = pressure difference across the filter, pa r = radius of the capillary in the filter bed, m L = thickness of the filter cake (capillary length), m = viscosity of filtrate, pa s If the cake is composed of a bulky mass of particles and the liquid flows through the interstices (correspond to a multiplicity of capillary tubes), then the flow of liquids through these may be expressed by poiseulleââ¬â¢s equation. Darcyââ¬â¢s Equation: Poiseuilleââ¬â¢s law assumes that the capillaries found in the filter are highly irregular and nonuniform. Therefore, if the length of a capillary is taken as the thickness of the bed, correction factor for radius is applied so that the rate equat ion is closely approximated and simplified. The factor influencing the rate of filtration has been incorporated into an equation by Darcy, which is: KA P V = ââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬â ? L Where, K = permeability coefficient of the cake, m2 A = surface area of the porous bed (filter medium), m2 p = pressure difference across the filter, pa L = thickness of the filter cake (capillary length), m ? = viscosity of filtrate, pa s The term K depends on the characteristics of the cake, such as porosity, surface area and compressibility. Permeability may be defined quantitatively as the flow rate of a liquid of unit viscosity across a unit area of cake having unit thickness under a pressure gradient of unity. This model relates not only to filter beds or cakes but also applies to other types of depth filter. Equipment is valid for liquids flowing through sand, glass beads and various porous media. Darcyââ¬â¢s equation is further modified by including characteristics of K by Kozeny-Carman. Kozeny-Carman Equation: Poiseuilleââ¬â¢s equation is made applicable to porous bed, based on a capillary type structure by including additional parameters. Thus the resultant equation, which is widely used for filtration is Konzeny- Carman equation. A p ? 3 ?S2 KL (1- ? )2 V = ââ¬âââ¬â ââ¬âââ¬â- ââ¬âââ¬âââ¬â Where, ? = porosity of the cake (bed) S = specific surface area of the particles comprising the cake, m2/m3 K = Konzeny constant p = pressure difference across the filter, pa L = thickness of the filter cake (capillary length), m ? = viscosity of filtrate, pa s The Konzeny constant is usually taken as 5. The effect of compressibility of the cake on flow rate can be appreciated from equation (1), since the flow rate is proportional to ? 3/ (1- ? )2. A 10 percent change in porosity can produce almost 3-fold change inn V. Limitations of Kozeny Carman equation: Kozeny Carman equation does not take in to account of the fact that the depth of the granular bed is lesser than the actual path traversed by the fluid. The actual path is not straight throughout the bed, but it is sinuous or tortuous Mechanisms of filtration: The mechanism whereby particles are retained by a filter is significant only in the initial stages of filtration. Some of the mechanisms are: Straining: Similar to sieving i. e. , the particles of larger size cannot pass through the smaller pore size of the filter medium. Impingement: Solids having momentum move along the path of streamline flow and strike (impinge) the filter medium. Thus, the solids are retained on the filter medium. Entanglement: Particles become entwined (entangled) in the mass of fibres (of cloth with a fine hairy surface or porous felt) due to smaller size of particles than the pore size. Thus the solids are retained on the filter medium. Attractive forces: Solids are retained on the filter medium as a result of attractive forces between particles and filter medium, as in case of electrostatic precipitation. FILTER MEDIA AND FILTER AIDS Filter media: The filter medium act as a mechanical support for the filter cake and is also responsible for the collection of solids. Filter medium should have the following characteristics: 1. It should have sufficient mechanical strength. 2. It must be inert; it should not show chemical or physical interaction. 3. It should not absorb the dissolved material. 4. It should allow the maximum passage of liquid, while retaining the solids. It means that it must offer low resistance to flow. The magnitude of the resistance of the filter medium will change due to the layers of solids deposited earlier, which may block the pores or may form bridges over the entrances of the channels. Therefore, the pressure should be kept low at the beginning to avoid the plugging of the pores. The usual procedure is to filter at constant rate by increasing the pressure as necessary. When normal working pressure is reached, it is maintained. On continued filtration, the thickness of the cake further builds up and hence the rate of filtration decreases. When the rate is uneconomical, filtration is stopped. The filter cake is removed and filtration is restarted. Materials: The following materials are used as filter media: 1. Woven materials such as felt or cloth: * Woven material is made of wool, cotton, silk, glass, metal or synthetic fibres (rayon, nylon etc. ) * Synthetic fibres have greater chemical resistance than wool or cotton, which are affected by alkali and acid respectively. * The choice of the fibre depends on the chemical reactivity with the slurry. . Perforated sheet metal: * For eg: stainless steel plates have pores which act as channels as in case of meta filter (edge filter). 3. Bed of granular solid built up on a supporting medium: * In some processes, a bed of graded solids may be formed to reduce the resistance to the flow. * Typical examples of granular solids are gravel, sand, asbestos, paper, pulp an d keiselguhr. * The choice of solids depends on the size of the solids in the process. 4. Prefabricated porous solid unit: * Porous solids prefabricated into a single unit are being increasingly used for its convenience and effectiveness. Sintered glass, sintered metal, earthenware and porous plastics are some of the materials used for the fabrication. 5. Cartridge filter media: * Cartridge units are economical and available in pore size of 100à µm to even less than 0. 2 à µm. * These can be used either as surface cartridges or depth type cartridges. a) Surface type cartridges: * These are corrugated and resin treated papers. These are used in hydraulic lines. * Ceramic cartridges are advantageous in cleaning for reuse by back flushing or firing. * Porcelain filter candles are used for sterile filtration. ) Depth type cartridges: * These are made of cotton, asbestos or cellulose. * These are disposable items, since cleaning is not feasible. Filter Aids: Filter aid forms a surface deposit which screens out the solids and also prevents the plugging of the supporting filter medium. The important characteristics of the filter aids are: 1. Chemically inert to the liquid being filtered and free from impurities. 2. Low specific gravity, so that filter aids remain suspended in liquid. 3. Porous rather than dense, so that previous cake can be formed. 4. Recoverable Justification: The object of the filter aid is to prevent the medium from becoming blocked and to form an open, porous cake, hence reducing the resistance to flow of the filtrate. a) Usually low resistance is offered by the filter medium itself, but as layers of solid built up the resistance will be increased. The cake may become impervious by blocking of the pore in the medium. Flow rate is inversely proportional to the resistance of the solid cake. b) Slimy or gelatinous material and highly compressible substances form impermeable cakes. The filter medium gets plugged and the flow of filtrate stops. Disadvantages: * The filter aids remove the coloured substances by absorbing them. Sometimes active principles such as alkaloids are absorbed on the filter aid. * Rarely, filter aids are a source of contaminants such as soluble iron salts, which can provoke degradation of sensitive ingredients. * Liquid retained in the pores of the filter cake is lost in the manufacturing process. Example of filter aids: * Keiselguhr, Talc, Charcoal, Asbestos, Paper pulp, Bentonite, Fullers earth * Activated charcoal is used for removal of organic and inorganic impurities. Keiselguhr is a successful filter aid and as little as 0. 1% can be added to the slurry. The rate of filtration is increased by 5 times or more, at the above concentration, though the slurry contains 20% solids. Handling of filter aids: Filter aids are mostly used for clarification processes, i. e. , where solids are discarded. Different flow rates can be achieved depending on the grade of the aids. * Low flow rate (fine solids) â â¬â fine grade filter aids ââ¬âmainly intended for clarity. * Fast flow rate (coarse solids) -coarse grade filter aids ââ¬âacceptable filtrate. The filter aid can be employed in either one or both ways. a) Firstly, a pre coat is formed over the medium. For this purpose, a suspension of the filter aid is filtered to give a coating up to 0. 5/m2. b) Secondly, a small proportion of filter aid (0. 1-0. 5% of total batch weight) is purposely added to the slurry. So the filter cake has a porous structure and filtration can be efficient. The filter aid of 1-2 parts per each part of contaminant is mixed in the feed tank. This slurry is re circulated through the filter until a clear filtrate is obtained. Filtration then proceeds to completion. The body mix method minimises equipment requirement and cross contamination potentials. Sterile Filtration: Sterile filtration is carried out for removal of microorganisms from fluids. It is a cheap and satisfactory method for sterilizing heat-sensitive (thermolabile) materials. The method implies the use of membrane filters which do not impart any particulate matter, fibers, or chemical reaction to the filtrate unlike unglazed porcelain candles, asbestos pads and other filters. In addition, no pretreatment is required, cleaning is no problem and the filters can be autoclaved or gas sterilized after assembly in its holder. Even when sterility is not warranted but ââ¬Ëpolishingââ¬â¢ (removal of particulate matter including live or dead bacterial cells in order to obtain high purity and clarity) is desired in products like oral or topical antibiotic preparations, membrane filters are the best choice. The following filters are used for bacterial filtration: 1. Candle filter 2. Seitz filter 3. Edge filter 4. Sintered glass filter 5. Membrane filter Candle filters: Candle filters are made of unglazed porcelain and are available in various porosity grades, either cylindrical or in the shape of the flanged test tube. Normally the filtration is so carried out that the liquid flow is from is from outside inwards and greater filtration surface is available to the incoming liquids. Candle filters can be sterilized by steaming, by hot moist air, or by autoclaving. Cleaning may be affected by drawing a large volume of distilled water through the candle filter thereby completely washing the previous solution from the pores. Thus the surface of the filter should be gently scrubbed with a soft brush, rinsed well with water and finally ignited in a muffle furnace. The main disadvantage of such filters s that the pores become plugged with organisms and debris which necessitate a very thorough cleaning. Sietz filter: It consists of an asbestos pad. The pads are available in several porosities that make them valuable for ââ¬Ëpolishingââ¬â¢ of solutions as well as removal of bacteria. Unless however the filter is backed with nylon mesh or sintered stainless steel: fibers occasionally get into the solutio n. The lower edge is fitted with a broad flat flange and the upper part is cylindrical. A perforated plate fitted into a lower part of the funnel supports the asbestos pad. As the pads are meant only for single use, the cleaning of filter media is no problem. Each time a fresh pad is to be used. The apparatus is simple in operation but suitable mostly for small quantities of liquids. Sintered glass filters: These are made of borosilicate glass. Borosilicate glass is finely powdered, sieved and particle of desired size are separated. It is then packed in to a disc mould and heated to a temperature at which adhesion takes place between the particles. The disc is then fused to a funnel of suitable shape and size. The sintered glass filters are available in different pore size. Hence the funnel with a sintered filter is numbered according to the pore size. The filtration is carried out under reduced pressure. These funnels are used for bacterial filtration. Sintered filters are also available in stainless steel which has a greater mechanical strength. However these are very much liable to attack by the solutions passing through them. Edge filters: In edge filters a pack of the filter media used and filtration is done edges by passing the liquid or slurry between and not through the media. Such filtration must be conducted under pressure or under partial vaccum system. Meta filter and stream line filter are two types of edge filters but the former is of greater use in pharmaceutical industry. Meta filters: Meta filters are useful in those manufacturing processes where filter presses are not frequently suitable. It requires no cloth, gauges, paper etc. and may be used at any pressure and temperature and for any liquid. It can be thoroughly cleaned after each operation. In its simplest form, meta filters consists of a grooved drainage rod or guide tube on which a series of rings are packed. On keeping the pack and finds its way along the grooves in drainage rod and ultimately to the receiver. These may be operated with pressure or under vaccum system. The rings are usually of stainless steel, of about 15mm inside diameter, 22mm outside diameter and 0. 8mm in thickness, with a number of semicircular projections on one surface. These pressure filters can be used for the filtration of very viscous liquids such as syrups or oils by fitting a steam jacket and rendering the liquids less viscous. They are also useful in the clarification of injection solutions and products such as insulin liquids. This type of filter can be cleaned easily by back-flushing with water or steam. Because of the shape of the pores in the ring, back-flushing will wash away the filter bed completely. Meta filters are very economic in use. Streamline filters: Operation wise and also geometrically, the streamline filter is similar to meta filter but the cylindrical filter pack consists of compressed paper discs. The liquid flow takes place radially inwards through the small space between individual papers and through the papers themselves. Membrane filters: * Ultra filtration methods have become popular in recent years mainly due to increased refinement of various membranes. Cellulose and cellulose derivatives are mostly commonly used materials for these filters. They are available in a wide range of pore sizes, ranging from 8à µ down to 0. 22à µ. * However, for sterile filtration, membranes with pore size of 0. 22 to 0. 45à µ are usually specified. * As such fine porosity of membranes may get clogged rapidly, a prefilter is used to remove colloidal matter in order to extend th e filtration cycle. * The filter primarily acts as a simple screen and retains on its surface all particles of size greater than the pore size of the filter (resembling sieving action). Due to an enormous number of very fine pores, the pore volume approximates 80% of the total volume of the membrane. * The action of the filter is mainly due to the combined forces of gravity and van Der Waals forces. * Membrane efficiency can be predicted in terms of its bubble point which is a characteristic function of porosity. It is defined as the pressure required to push air through a liquid saturated filter. Filter pores retain liquid until this point is reached. * Each membrane has specific bubble point which depends on the liquid wetting the membrane. An obvious disadvantage of membrane filter is their brittleness when dry and this makes handling difficult. The use of filters in cartridge form, overcomes this problem. * Apart from the small laboratory models, large models are available for p ilot plant and small scale production to handle up to about 25litres/minute of liquid through a 0. 45à µ pore size membrane. * Membrane filters find extensive use in filtration and sterilization of a variety of pharmaceutical products such as ophthalmic and intravenous solutions, other aqueous products, biological preparations, hormones and enzymes. In conjunction with a suitable pipette syringe, it is very useful in dispensing measured volumes of sterile fluids. * This assembly is often utilized for handling of pharmaceutical, biological and bacteriological preparations which can be damaged by metallic contact. Centrifugation Centrifugation is a unit operation employed for separating the constituents present in the dispersion with the aid of the centrifugal force. Equipment used for centrifugation is centrifuge. Centrifugal force is used to provide the driving force for the separation. It replaces the gravitation force in the sedimentation. Centrifugation is particularly useful when separation by ordinary filtration is difficult. Centrifugation provides convenient method of separating two immiscible liquids or solid from liquid. * Centrifugation is a separation process which uses the action of centrifugal force to promote accelerated settling of particles in a solid-liquid mixture. * If particles size in the dispersions is 5 micro meter or less, they undergo Brownian motion, hence they do not Sediment under gravity, therefore a stronger force, centrifugal force is applied in order to separate Two distinct major phases are formed in the vessel during centrifugation: Theà sediment Usually does not have a uniform structure. Theà centrifugateà orà centrateà which is the supernatant liquid. Process of centrifugation: The centrifuge consists of a container in which mixture of solid and liquid or two solids is placed and rotated at high speeds. The mixture is separated into itââ¬â¢s constituent parts by the action of the centrifugal force on their densities. A solid or liquid with higher specific gravity is thrown outward with greater force & it is retained at the bottom of the container leaving a clear supernatant liquid. The speed of the centrifuge is commonly expressed in terms of number of revolutions per minute. Theory of centrifugation: If a particle (mass = m kg) spins in a centrifuge (radius r, m) at a velocity (v, m s-1) then the centrifugal force (F, N) acting on the particle equals m v2/r. The same particle experiences gravitational force (G, Newton) = m g (where g = acceleration due to gravity) Centrifugal force = f = mv2/r Centrifugal effect (C) = F/G = mv2 /mgr (v = 2 ? r n ) c = (2? r n)2/ g r = 4 ? 2r n2/ g (d= r/2) = 2 ? 2 d n2/ g (g = 9. 807) C = 2. 013 d n2 Centrifugal effect, C= 2. 013 n2d n= speed of rotation( revolution per second of centrifuge) * d= diameter of rotation So * Centrifugal effect is directly proportional to diameter of rotation * Centrifugal effect is directly proportional to (speed of rotation)2 There are two main types of centrifuge used to achieve separation on an industrial scale, * Filtration centrifuge: Those using perforated baskets, which perform a filtratio n-type operation (work like a spin-dryer) and * Sedimentation centrifuge : Those with a solid walled vessel, where particles sediment towards the wall under the influence of the centrifugal orce Perforated basket centrifuge: Figure: Perforated Basket Centrifuge In this type of centrifuge, a basket is mounted above a driving shaft. This type of centrifuges are used for batch processes. Principle: Perforated basket (bowl) centrifuge is a filtration centrifuge. The separation through a perforated wall based on the difference in the densities of solid and liquid phases. The bowl contains a perforated side wall. During centrifugation, the liquid phase passes through a perforated wall, while solid phase is retained in the bowl. The solids are removed after stopping the centrifuge. Construction: It consists of a basket, made of steel (sometimes covered by vulcanite or led) or copper. The material of construction should be such that it offers greatest resistance to corrosion. The basket may have diameter of 0. 90 meters and capacity of 0. 085 meter cube. The diameter of perforations must be based on the size of crystals to be separated. The basket is suspended on a vertical shaft and is driven by a motor using suitable power system. Perforated basket is kept in a casing which collects the filtrate and discharges it through outlet. Working: The material to be separated kept in the basket. The loading of material must be done to give an even distribution. The power is applied to run the basket at speed of 1000 rpm. During centrifugation the liquid passes through the perforated wall and solid phase retaind in the basket. Uses: * Perforated basket centrifuge is extensively used for separation of crystalline drugs (aspirin) from mother liquor. Sugar crystals are separated using the perforated basket centrifuge. * Precipitated proteins from insulin can be separated. Advantages: * The process is rapid * The final product has low moisture content * It cam handle slurries with high proportion of solids even those having paste like consistency * Dissolved solids from cake can be separated. Disadvantages: * On prolonged operation solids may form hard cake. * It is a batch process. Non-Perforated Centrifuge: Principle This is sedimentation centrifuge. The separation is based on the difference in the densities of solid and liquid phases without a porous barrier. The bowl contains a non perforated side wall. During centrifugation, solid phase is retained on the sides of the basket and liquid remains at the top removed by skimming tube. Construction: It consists of a basket, made of steel (sometimes covered by vulcanite or led) or copper. The material of construction should be such that it offers greatest resistance to corrosion. The basket is suspended on a vertical shaft and is driven by a motor using suitable power system Working: The feed is continuously introduced into the centrifuge while the liquid (centrate) is continuously removed from an overflow weir inside the centrifuge * Solids build up during centrifugation forming a cake that must be periodically discharged Figure: Non-Perforated Basket Centrifuge * After the basket becomes filled with solids the centrifuge slows down and ââ¬Å"skimmingâ⬠(the removal of the top semi-liquid soft cake layer) takes place * Skimming typically removes 5 to 15% of the bowl solid volume * The bulk of the cake is discharged using a ploughing knife moving into the slowly rotating cake * The solid is discharged centrally at the bottom of the centrifuge * Solid accumulation is typically up to 60 to 85% of the maximum available depth * This type of centrifuge is typically operated at low centrifugal forces and has a relatively low solid handling capacity. The imperforated basket centrifuge is the only basket centrifuge commonly used for typical sludge dewatering applications. * High solid recovery can be achieved with this centrifuge even without chemical additives. Uses: Non-perforated basket centrifuge is useful when deposited solids offer high resisttance to the flow of liquid. Conical disc centrifuge: Principle: It is a sedimentation centrifuge. The separation is based on the difference in the the densities between phases under the influence of centrifugal force. In this a number of cone shaped plates are attached to the central shaft (which has provision for feed) at different elevations. During centrifugation, the dense solids are thrown outwards to the underside of cone shaped casing. While lighter clarified liquid passes over bowl and collected from top of the cone. Construction: It consists of shallow form of bowl containing series of conical discs attached to the central shaft at different elevations. The discs are made up of thin sheet of metal or plastic separated by narrow spaces. A concentric tube is placed surrounding the central drive shaft. Working: The feed is introduced into the concentric tube surrounding the drive shaft. The feed flows down and enters the spaces between the discs. The solids and heavier liquids thrown out ward and move underside of the discs. Low speed and short time of centrifugation is sufficient to give high degree of clarification. Uses: * Two immiscible liquids can be easily separated by continuous process after liquid-liquid extraction in manufacture of antibiotics. * Precipitated proteins in manufacture insulin can be clarified. Advantages: * Conical disc centrifuge is compact and occupies very less space. * By controlling speed of rotation and rate of flow, particles are separated into two sizes. * Separating efficiency is very high. Disadvantages: * Capacity of conical disc centrifuge is limited * Construction is complicated * Not suitable if sediment of solids form hard cake. Figure: Conical Disc Centrifuge Tubular bowl centrifuge: The tubular bowl centrifuge has been used for longer than most other designs of centrifuge. It is based on a very simple geometry: it is formed by a tube, of length several times its diameter, rotating between bearings at each end. The process stream enters at the bottom of the centri fuge and high centrifugal forces act to separate out the solids. The bulk of the solids will adhere on the walls of the bowl, while the liquid phase exits at the top of the centrifuge. * As this type of system lacks a provision of solids rejection, the solids can only be removed by stopping the machine, dismantling it and scraping or flushing the solids out manually. Tubular bowl centrifuges have dewatering capacity, but limited solids capacity. Foaming can be a problem unless the system includes special skimming or centripetal pumps. Figure: Tubular bowl centrifuge * This type of centrifuge can also be used to separate immiscible liquids. * Rate of sediment can be control by controlling the inlet rate. * The uses of centrifugal sedimenters include liquid/liquid separation, e. g. during antibiotic manufacture and purification of fish oils, the removal of very small particles, the removal of solids that are Compressible and which easily block the filter medium, The separation of bloo d plasma from whole blood (need C =3000).

The best ways to beat work procrastination
The best ways to beat work procrastination Are you such a compulsive procrastinator that youââ¬â¢ve even found a way to put off figuring out how to overcome procrastinating? If things have gotten that bad, itââ¬â¢s likely time to make a positive change in your life. The effects of procrastination on your life can be far-reaching and extreme if you let things get out of hand- everything from avoiding individual growth and missing out on opportunities to constantly disappointing people in your personal and professional orbits are common for those who choose this behavior pattern. The results can have a negative impact on your life path and well-being- both in the short-term and over the long haul.Step back and take a personal inventory of your typical habits and behaviors. All aspects of your life are fair game- from your work life to relationships with friends and family to handling your personal responsibilities and chores on a daily basis. Be honest: are you often guilty of putting things off? Do people in your life ro utinely call you out for avoiding important tasks? Has procrastination taken its toll and left you with a series of regrets and lost chances? If youââ¬â¢ve answered yes to any or all of these questions, itââ¬â¢s no wonder youââ¬â¢re looking for ways to end this destructive cycle and stop putting things off as a matter of habit.If youââ¬â¢ve decided not to procrastinate any longer and address your problem, then consider the following strategies to put it in your rearview mirror.1. Have a to-do checklistIf feeling overwhelmed by a nebulous and free-floating list of tasks often leads to your procrastination behavior, then try organizing your daily to-dos into a structured checklist. By using a straightforward and easy-to-follow checklist, you can clearly see exactly what you need to take care of each day and chart your progress, which can be a great motivating tool in itself- the more you get done and the more checkmarks you see on your list, the more motivated youââ¬â¢l l be to push forward and finish your chores!2. Avoid non-functional multitaskingSure, these days the average person juggles multiple activities at any given time during the day, but is it affecting your ability to stay focused and on task enough to follow it through to the end? Everything from texting while on the phone to watching YouTube videos while finishing up key assignments has become standard operating behavior, but for some people, this type of ââ¬Å"multitaskingâ⬠really just keeps them from confronting- and completing- the things they need to get done. If this sounds painfully familiar, then you may be spreading yourself too thin or making it too easy for your focus to shift away from your priorities. When facing an important task, try giving it all of your attention and effort instead- not only will it be easier to finish, but youââ¬â¢ll also likely complete it faster, which means you can move on to other (possibly more fun) things quicker.3. Break down big task s into manageable chunksDo the size and scope of difficult, complex, and multi-step projects send you running in the opposite direction? If so, then get strategic and break down big tasks into manageable steps that donââ¬â¢t fill you with fear and anxiety. Thereââ¬â¢s an old saying that ââ¬Å"a journey of 1,000 miles begins with a single step,â⬠and the same notion holds true for large-scale projects. When faced with a big ââ¬Å"1,000-mileâ⬠task, lay out all the steps you need to take to get to the end, and then take them on one at a time.4. Give yourself positive reinforcements and negative consequencesThe truth is, youââ¬â¢re likely your own best ââ¬Å"overseerâ⬠when it comes to getting things done, and youââ¬â¢re in the perfect position to treat yourself for staying on task- and conversely, providing the appropriate consequences when you procrastinate. When it comes to staying motivated and focused, thereââ¬â¢s nothing like a little reward for a job well done at the end to keep you on task. Also, the desire to avoid a negative consequence can be equally as motivating as you fight against yourà evasive behavior.If youââ¬â¢re tired of procrastination and the negative effects of putting things off have taken its toll on your life, then use the strategies presented here to break free from these unhealthy behavior patterns and make positive and lasting changes in your life.

A Ways To Go
A Ways To Go A Ways To Go A Ways To Go By Maeve Maddox A reader wonders about the expression ââ¬Å"to have a ways to goâ⬠: I thought this was just a California quirk and a recent one at that, but I found it used by Dashiel Hammet in one of his stories, so it has been used for nearly a century. He was of course a California writer, so maybe there is a California connection, although its use seems to have spread nationwide. Unlike anyways, which is viewed as nonstandard on both sides of the Pond, ââ¬Å"a ways to goâ⬠seems to have achieved standard status in US English. And while that particular phrase could owe its modern popularity to California-speak, the following OED citation in the entry for way in the sense of distance is dated 1588: They..came vnto the gates of the cittie, after they had gon a good wayes in the suburbs. [They..came unto the gates of the city, after they had gone a good ways in the suburbs.] An OED note points out that the ââ¬Å"origin of the use of ways for way is obscureâ⬠and that the usage is ââ¬Å"now only dialect and U.S.â⬠The Ngram Viewer shows the phrase ââ¬Å"a ways to goâ⬠in use as early as 1884, but its present popularity seems to have begun in the late 1960s. The following recent examples show the phrase used in a variety of contexts to indicate that a person or entity has more work to do in order to achieve a desired goal: Their disconnect on the immigration reform issue suggests the party still has a ways to go in bridging the gulf between the two.- CNN. Ryan Mallett shows promise, but Texans QB has a ways to go- NFL site headline Some scientists share better than others. While astronomers and geneticists embrace the concept, the culture of ecology still has a ways to go. - Michigan State University site. According to the Public Policy Institute of California, 69 percent of Californians have broadband at home- a ways to go from the stateââ¬â¢s goal of 80 percent by 2015.- Encyclopedia of Human Memory, 2013. 13 Years Later, Still a Ways to Go on Sharing Terrorist Threats With Publicà - National Defense Magazine. The Navy has made great improvements in race relations, but weve still got a ways to go.- US Defense Department site. IRS has a ways to go before meeting e-file adoption goal- IT site headline. I think we have a ways to go as far as really explaining the value of the Common Core showing how data that is gathered is secure so parents dont need to worry about that.- Superintendent of a Vermont school district.à ââ¬Å"A ways to goâ⬠has a more folksy sound than ââ¬Å"a way to go.â⬠It may also suggest that the remaining distance to be traveled is longer than what would be indicated by ââ¬Å"a way to go.â⬠Want to improve your English in five minutes a day?

The Ultimate Value of Promoting Respect in Schools
The Ultimate Value of Promoting Respect in Schools The value of respect in school cannot be undersold.Ã It is as powerful of a change agent as a new program or a great teacher.Ã A lack of respect can be downright detrimental, completely undermining the mission of teaching and learning.Ã In recent years, it seems that a respectful learning environment is almost non-existent in many schools across the country. It seems that there is a handful of daily news stories highlighting disrespect levied against teachers by students, parents, and even other teachers. Unfortunately, this is not a one-way street. You regularly hear stories regarding teachers who abuse their authority one way or another.Ã This is a sad reality that needs to change immediately. Teachers and Respect How can teachers expect their students to respect them if they are not willing to be respectful to their students?Ã Respect must often be discussed, but more importantly, regularly modeled by teachers.Ã When a teacher refuses to be respectful to their students, it undermines their authority and creates a natural barrier that hinders student learning.Ã Students will not thrive in an environment where the teacher oversteps their authority. The good news is that most teachers are respectful towards their students on a consistent basis. Just a few decades ago, teachers were revered for their contributions. Sadly, those days are seemingly gone.Ã Teachers used to get the benefit of the doubt. If a student made a poor grade, it was because the student was not doing what they were supposed to be doing in class. Now, if a student is failing, the blame is often laid on the teacher. Teachers can only do so much with the limited time that they have with their students. It is easy for society to lay blame on the teachers and make them the scapegoats. It speaks to the general lack of respect for all teachers. When respect becomes the norm, the teachers are impacted significantly as well. Retaining and attracting great teachers becomes easier when there is an expectation of a respectful learning environment. No teacher enjoys classroom management. There is no denying that it is a critical component of teaching. However, they are called teachers, not classroom managers.Ã A teachers job becomes much simpler when they are able to utilize their time to teach rather than disciplining their students. This lack of respect in schools can ultimately be traced back to what is taught in the home. To be blunt, many parents fail to instill the importance of core values such as respect as they once did.Ã Because of this, like many things in todays society, the school has had to take on the responsibility of teaching these principles through character education programs.Ã Schools must intervene and implement programs that foster mutual respect in beginning grades. Instilling respect as a core value in schools will improve the overculture of a school and ultimately lead to more individual success as students feel safe and comfortable with their environment. Promote Respect in Schools Respect denotes both a positive feeling of esteem for a person and also specific actions and conducts representative of that esteem. Respect can be defined as allowing yourself and others to do and be their best. It is the goal of Any Where Public Schools to create a mutually respectful atmosphere between all individuals involved within our school including administrators, teachers, staff members, students, parents, visitors. As such, all entities are expected to remain respectful to each other at all times. Students and teachers especially are expected to greet each other with kind words and student/teacher exchanges should be friendly, in an appropriate tone, and should remain respectable. The majority of student/teacher interaction should be positive. All school personnel and students are expected to use the following words that show respect for another person at the appropriate times when addressing each other: PleaseThank YouYoure WelcomeExcuse MeMay I Help YouYes Sir, No Sir or Yes Maam, No Maam

Research paper Example | Topics and Well Written Essays - 1000 words - 9
Research Paper Example Foner reveals that prior to the trial, the defendants enjoyed access to lawyers. Consequently, the defendants had insignificant time for planning defense. 2 He has added that, the defendants appealed against the above ruling on the basis of inadequate legal counsel. Notably, the supreme court of Alabama ruled by a vote of six against one that there was a fair trial. Considerably, it is noteworthy pointing out that Anderson, the chief justice, produced a tough nonconformist opinion that resulted to an appeal to the Supreme Court in the US against the ruling. The Courtââ¬â¢s Ruling Hoffmann et al indicates that, during the ruling, the supreme USââ¬â¢s Supreme Court majority opinion overturned and remanded the ruling of the supreme court of Alabama, maintaining that the court had violated the due process. Notably, the Supreme Courtââ¬â¢s decision rested on three significant arguments; firstly, the defendants did not receive fair, unbiased and purposeful trial. Secondly, they di d not access the right of counsel, with the familiar consultation incidents and a chance for trial. Lastly, the trial took place before juries chosen racially from unqualified people; hence systematically excluding qualified juries. It is worthwhile noting that the conviction was unlawful since the accused did not access the counselââ¬â¢s assistance right from their arraignment up to the commencement of their trial. This led to breaching the due process section of the 14th Amendment. Foner indicates `that the section, counsel has to be certain to anybody subject to the likelihood of a death sentence, be it in state or else federal courts.3 Conclusively, our group does not support the courtââ¬â¢s ruling because as indicated above, had interfered with state courts; hence, going beyond its jurisdiction. Consequently, our group has agreed with the above discussed dissenting opinions because the trial court had really acted upon the laid down procedures. The only missing point is t he lack of representation for the defendants. However, one should note that a court has its own individual reasons to at times deviate from norms especially if the situation calls for the same. Notably, the US Supreme Court did not conduct situational analysis before delivering its ruling. 4 Consequences/implications of the Ruling Assuming the court it is absolutely devoid of merit, all other claims that the petitionersââ¬â¢ constitutional rights got violated, positions its viewpoint and ruling upon a solitary declaration of reality. Furthermore, the petitioners did not access the right of counsel, with the familiar consultation incidents and preparation opportunity for trial. If this is factual, they were deprived of the due process of law; hence, they were at liberty to have the rulings against them upturned, however, there are no records for such denial. Hoffmann et al argues that nine defendants, together with Patterson, were charged for one condemnation, and he was as well u nconnectedly indicted. As opposed to trying using the en masse, the government provided four trials; hence lessening the risk of error and unfairness that unavoidably attends an effort in a particular trial to determine the culpability or blamelessness of the accused.5 Dissenting opinions If right, the judgment that the malfunction of the trial court to grant petitioners time as

See document - Essay Example Company senior managers heading public companies prepared deceptive statements to blow up the prices of the company stock, apparently undermining the trust of the public in the integrity of financial market and regulators. The corporate scandals are usually perpetrated by several people who understand the organizationââ¬â¢s every single detail, with most collaborating parties being people with high standing in the society. Most executives in failed corporations admit receiving enormous bonuses and backdated stock options to warrant that they will make wealth from investing in their company; not considering whether their performance made the share price increase or go down. Other unethical behaviors have resulted in the downfall of corporations, poor performance and negative publicity. As a result, the aspect of ethics in organizations has increasingly gained prominence due to distrust on organizational leaders (Loe, Ferrell & Mansfield, 2000) This study seeks to examine some of th e corporate failures, reasons behind their fall, as well as a close examination as to where blame may be assigned. Of specific importance, Enron downfall and Satyam scandals will be useful in examining ethics behind corporationsââ¬â¢ failure. The paper will also look at the theories that expound on the subject of ethical governance in organizations. Ethics is a significant pillar in the modern corporate arena and corporate governance. Organizations have learnt useful lessons from the above cases on the danger that unethical decisions can bring in any organizations. As David Thoreau once said, ââ¬Å"it is truthfully sufficiently said that a firm has no conscience; but a company of conscientious men is a corporation with ethicsâ⬠. This statement carries a lot of meaning with it as to the significance of upholding ethics in organizations. The subject of what constitutes ethical behavior in organizations remains a debatable subject due to the wide ranging opinions of what const itutes ethics, and what ethics is not. Nevertheless, many organizations have embraced ethical codes stating their leading philosophical guidelines and organizational values. Ethical codes that are successful highlight the obligations of organizations to shareholders, the behavior anticipated of employees, and ethical parameters of the organization. Ethical codes are intended to impact on employee behavior, and are also referred to as corporate ethics statements. Business ethics field deals with questions as to whether a particular business practices are acceptable. Controversial business ethics issues arise on a daily basis in every organization, and this calls for organizational members to exercise their conscience as Thoreau said. For illustration, an accountant may face an ethical dilemma in his/her course of duty that may compromise her decision. For instance, if an accountant discovers inaccuracies in a clientââ¬â¢s auditing report, he/she may opt to report the inaccuracy. O n the other hand, reporting such an inadequacy may result in the auditing company fired by the client for disclosing the inadequacies. This confusion leaves the accountant at crossroads as to what practice is acceptable. Business ethics require that organizational members to conform to sound moral principles. Special consideration has to be put into perspective when applying the concept of ethics in business. One is that businesses are formed with the aim of making a profit, and therefore, businesses

United State foreign policy towards Middle East Essay
United State foreign policy towards Middle East - Essay Example US has been accused of having inconsistent and incoherent foreign policy towards Middle East. The relation of United States government and the Middle East can be dated to a thousand years and since this period it has used various foreign policies in this region. Oren admits that the Americaââ¬â¢s failure to be clear and honest about its own motives, as much as its serial failure to interpret the Middle East as often befuddled relations with the region (Oren,pp.341). This paper explores the reasons for United States inconsistent foreign policy towards Middle East with a close reference to the text book power, faith, and fantasy: America in the Middle East 1776 to present. Combating Threat from Middle East and Adjacent Regions. The threat posed by Saddam Hussein in Iraq was fantastical and not real until the American forces hit the ground there. United states through its foreign policy seek to protect itself from Middle East threats while at the same time helping to safeguard the li ves of native people in the region. For example United States government has adopted different foreign policies in Iran and Iraq and also in Israel and Palestine. The United States foreign policy that is pegged on the pillars of deterrence, containment and preemptive strikes on terrorism and alleged terrorism attacks has been inconsistent and incoherent in Middle East.It has stressed force and sanctions and absence of nuclear weapons in Iraq and Iran while at the same employing diplomacy in Israel and Palestine and this has created a rather disparity and inconsistency in the foreign policy. (Parmar,pp.204). Pursuit of National Interest United States foreign policy is usually based on the national interest but in the Middle East, the pursuit encompasses overlapping, conflicting and inconsistent economic, political and strategic interest. Domestic influences usually determine the United States foreign policy and it is balanced by the interest of America and the greater good of mankind . Different political regimes in the United States also have their foreign policy blue prints and this has seriously led to the inconsistency of these policies towards Middle East. For example Democrats and Republicans have had different foreign policies towards Middle East once they are in power. There is usually more debate within the administration of United States government and the national security on foreign policy and it normally leads to contradictory, incoherent and inconsistent policy towards Middle East. Supply of Oil United States has depended on foreign crude oil for a long time and these imports are majorly from Middle East countries. Because of the massive petroleum reserves in the Middle East United States government has developed policies that are seen to be inconsistent and incoherent about the region. In view of this and the challenge posed by hostile domestic population, United States government has adopted an increasingly inconsistent policy in regard to the Mi ddle East region. The foreign policies are formulated in a careful strategy so as to wield acceptance from the Middle East masses and in the long run receive constant supply of crude oil. The need for secure flow of Middle Eastern oil into the United States economy has led to special relationship. The Middle Eastern countries especially Saudi Arabia has the largest deposit of oil reserves in the world but at the same time they are marred by instability. This instability is mainly caused by political regimes which are authoritarian. United States government through its foreign policy is supporting these political regimes in the Middle East in order to secure constant flow of oil (Rosati and Scott,pp.35). As a result, the United States government has preserved the status quo politics in the Middle East particularly in Saudi Arabia and the Persian Gulf sheikdoms. One of the major reasons for the inconsistent foreign policy in the Middle Eas
Are Cell Phones Really Dangerous to People Research Proposal
Are Cell Phones Really Dangerous to People - Research Proposal Example The problem has been identified: children have often access to cell phones with the permission of their parents. This trend is extremely dangerous especially since scientists have set severe restrictions regarding the potential use of cell phones by children ââ¬â but these restrictions seem to be ignored by most of the people worldwide. At this point, the following problem appears: are cell phones really dangerous to people? This problem has been explored through a series of relevant studies. It is proved that cell phones can actually harm health; moreover, it seems that the risks for health can be severe for people of all ages. At the next level, it has been made clear that the ways in which cell phones can affect the health of humans can vary; the direct use of cell phone may be less harmful compared to the residence near a cell phone tower. Dr. Vini Khurana studied the effects of cell phones on health; his research led to the following findings: ââ¬Ëthe use of handsets for 10 years or more can double the risk of brain cancerââ¬â¢ (Geoffrey 2008). In the above study, is given on the fact that certain types of cancer can take quite long to develop ââ¬â even up to a decade; therefore, the above study ââ¬â having lasted for such period - provides a precise estimation of the potential effects of cell phones on the brain. Another important finding of the study of Khurana has been the following one: cell phones can be more dangerous from smoking; the above finding indicates the level of risk related to the use of cell phones but also the level at which cell phones intervene in daily activities have led to the development of addiction similar to smoking ââ¬â as this problem is revealed through the study presented above. The various aspects of the danger of cell phones for human health are analyzed in the article of Kovach (2007); in the above article reference is made to the findings of the research developed by George Carlo, a medical scientis t who has spent years on studying the effects of cell phones ââ¬â both of handsets and cell phone towers ââ¬â on health; his research lasted from 1993 up to 1999 and reveals a series of important aspects of the health risks related to the use of cell phones. The key findings of his study could be summarized as follows: a) cell phones are not tested as for their risks for health; they enter the market without any testing, as a result of a legislative gap of the period when these devices appeared ââ¬â the 1980s, b) cell phones can cause severe problems of health, even death, since they are involved in the continuous transmission of waves which can adversely affect the bio-field of humans (Kovach 2007); it is possible for this reason that cell phones have been also related to the changes in the DNA of their users ââ¬â as also highlighted below.Ã

To what extent should we make moral judgments about cultural practices Essay
To what extent should we make moral judgments about cultural practices from outside our own culture - Essay Example Those who recommend this hold that the world is sharply divided into separate societies, sealed units, each with its own system of thought. They feel that the respect and tolerance due from one system to another forbids us ever to take up a critical position to any other culture." (Midgley, 69) According to this perspective, moral judgment is a kind of coinage valid only in its country of origin and the author terms this position ass 'moral isolationism'. Midgley also maintains that it is not forced upon individuals, and indeed makes no sense at all, to make moral judgment about other cultures. Unlike the general thinking that such an attempt to make moral judgment about other cultures is a respectful attitude to other cultures, the author purports that one cannot respect what is entirely unintelligible to one and therefore it is not respectful attitude. Here, the author comes up with her central argument of the article and there is every reason to realize it as true and rational. As the author argues, it is essential for one to know enough about another person or culture in order to come up with an evenhanded judgment about the culture or person. Therefore, Mary Midgley makes some essential arguments concerning moral judgment of other cultures in her article "On Trying out One's New Sword" and a reflective analysis of the article helps us in determining to what extent we should make moral judgments about cultural practices from outside our own culture. The article "On Trying out One's New Sword" suggests a moral isolationism which lays down a general ban on moral reasoning with regard to making moral judgments about strange cultures. In order to establish her argument, the author makes use of some remote example from the classical Japanese with a verb which means 'to try out one's new sword on a chance wayfarer'. According to this example, the Samurai is required to try out this new sword on any wayfarer who was not another Samurai, and this action could injure his honor, offend his ancestors, and even let down his emperor. "Now when we hear of a custom like this, we may well reflect that we do not understand it; and therefore are not qualified to criticize it at all, because we are not members of that culture. But we are not members of any other culture either, except our own. So we extend the principle to cover all extraneous cultures, and we seem therefore to be moral isolationists." (Midgley, 70) Midgley also deals with certain fundamental questions about moral isolationism with reference to making moral judgments about strange cultures. First of all, she examines whether the isolating barrier work both ways or people in other cultures are equally unable to criticize others. According to her, outsiders can deliver perfectly good indictments, although it makes more than two weeks to make them demining. "Intelligent outsiders can progress in it, and in some ways will be at an advantage over the locals. But, if this is so, it must clearly apply to ourselves as much as anybody else." (Midgley, 70) The author also deals with the question whether the isolating barrier between cultures block praise as well as blame. It is important to make immaculate judgments about other

Mentoring and Clinical Supervision in Nursing Practice Essay
Mentoring and Clinical Supervision in Nursing Practice - Essay Example The apparent gap between the scholarship, academy, knowledge, and learning can actually only be bridged by a constant supervision while rendering clinical activity and care by the mentors of the mentees Although there is a growing concern regarding the frustration related to today's nursing environment, an attitude change is enough to beget drastic changes in the status of healthcare nursing. This is the time of rapid and phenomenal changes in the pattern of healthcare delivery mainly due to advancement in technology and progressive development of the cult of increasing application of research to accomplish evidence-based care (Mills, J.E., Francis, K.L., and Bonner, A., 2005). Despite the problem apparently is crucial, the solution to issues in the nursing work environment and nursing practice parallels it since the nurses have the opportunity to use the power that already exists in the role of bedside nurses, and that role is that of mentoring that involves clinical supervision in implementing practice. Through mentoring, the nurses can continue to create common bond, feelings of acceptance, and a sense of loyalty within the profession (Browne-Ferrigno, T. and Muth, R., 2004). Mentoring and clinical supervision are critical in nursing. ... Despite the current hectic environment, nurses must make the time to mentor and supervise juniors (Yegdich, T., 2000). Taking the example of critical care nursing that involves sound knowledge of instruments, gadgets, medicines, and the physiology of life, one can easily assume that experienced critical care nurses have a knowledge base of vast clinical expertise, and in that clinical area, nothing happens outside evidence-based practice, and therefore, management of care of the patients is not possible without the wisdom and expertise acquired over time (Jenkins, E., Rafferty, M., and Parke, S., 2000). Impact on Knowledge: Nurses who are blessed with both knowledge and expertise mainly due to extended clinical experience would naturally be called for these leadership roles including mentoring and clinical supervision in professional development of junior nurses. They are in a position to offer continuing education, to provide opportunity for growth, to encourage certification among the mentees and the supervised, and ultimately in this way, to facilitate the opportunity for the new nurse to network with others in her area (Rafferty, M.A., 2000). The nurses do have the power and capability to make a difference, thus, not only in the lives of the patients and their families cared for but also to imbibe energy and interest in the practice environment with continued mentoring and clinical supervision of one nurse at a time. It demands a belief and love for the job and confidence that changes can be brought about in the environment of work involving the care of the patients by a process of progressive and d evelopmental nurturing of those who will

Occupational Therapy In Brazil Health And Social Care Essay
Occupational Therapy In Brazil Health And Social Care Essay Brazil is located in Latin America. It is the fifth most populated country according to the US Department of State (US Department of State, 2010). Brazil is home to an estimated 196 million people (US Department of State, 2010). As indicated by the Brazilian government, Brazil is a presidential democracy. The country is often referred to as The Federative Republic of Brazil (Brazilian Government, 2005). The Brazilian government developed a policy named Zero Hunger. The Zero Hunger policy is described in this view: Zero Hunger is a public policy that aims at eradicating hunger and social exclusion. It is a policy because it expresses the Federal Governments decision to consider hunger a central national issue, rather than an individual fatality. It is public because apart from the State it involves society as a whole (Brazilian Government, 2005). Brazil has public and private options for healthcare. In reference to the Brazilian government the public healthcare is established for public treatment. An example of this development is preventative and outpatient care with programs being carried out in rural areas: sanitation, food safety and care for the elderly, women and children (Brazilian Government, 2005). Improvements for public and private healthcare are still growing (Brazilian Government, 2005). The country of Brazil has been influenced by Indian, European, and African cultures. The influences of these nations have created norms for the Brazilian people. For example, music is a widespread custom in Brazil that dates back to the 17th century (Brazilian Government, 2005). Brazil has six occupational therapy schools. To become an occupational therapist in Brazil, a student must complete four to five years of occupational therapy curriculum at the offering university. Depending on what university the student attends that wil l determine the duration of their schooling (World Federation of Occupational Therapists, 2004). Based on the research found for occupational therapy, Brazil appears to have a driving focus toward people with physical disabilities. Most of the research found pertained to physically disabled adults. However, there were few studies concerning pediatrics as well. For the most part, the focused research highlighted physical disabilities in the upper extremity. In addition, research was found that supported rehabilitation services, incorporates models for disabled adults returning to work, supports theories based on review, and functional advancements for persons who are disabled. In occupational therapy, we assist a population whose daily routine reveals disorganized doing and that faces difficulties in participating in the social and cultural world (Takatori Bemtempo, 2007, p. 48). This was quoted from a Brazilian study for children, but it could be taken into consideration for all levels of occupational therapy. The following paragraphs include research from Brazil used to educat e the world of occupational therapy. Work-related hand injures: Case analyses in a Brazilian rehabilitation service is the study conducted by Sampaio, Mancini, Sliva, Figueiredo, Vaz, and Alves, 2006, p. 803. This study promotes the idea that the results of this study provide evidence for functional gains in clients treated in a rehabilitation service and supply information about the relation between specific components and functional performance (Sampaio et.al, 2006, p. 803). This study by Sampaio et al., 2006, was designed to depict the changes in patients who underwent therapy at hospitals in Brazil. The treatment began after the patient had a work related accident. The accident resulted in the patient having an upper extremity disability. The patient was observed by an occupational therapist at two different times. The first time was at the entrance of treatment, and the other was at the release of their treatment. The authors included outside measurements in their study. The Canadian Occupational Performance Measur e (COPM) was used to assess participants self-perception of their occupational performance and satisfaction. COPM is a standardized functional assessment instrument in the format of a semi structured interview based on proposed for client-centered practice (Sampaio et al., 2006, p. 805). After rehabilitation was completed the grip strength of the patients had improved. Also there was an increase of the COPM at the time of discharge (Sampaio et al., 2006, p.806). In addition, more research by Figueiredo, Sampaio, Mancini Nascimento et al. (2006) also agrees that receiving intervention especially occupational therapy will increase the COPM and the grip strength. After the study was completed the research shows that people who have rehabilitation therapy will see significant increase in grip strength values, with mean value at discharge showing to be twice the magnitude observed at admission (Sampaio et al., 2006, p. 807). in Brazil, few rehabilitation services currently use client-ce ntered functional evaluation tools in clinical practice, and most are not familiar with such instruments. However, client-centered approaches are becoming popular within rehabilitation facilities, especially in North America (Sampaio et al., 2006). This study in Brazil is good for moving rehabilitation research forward because it demonstrates how research from other countries can be implemented. This shows that having countries create research together can enhance a common goal. Also, the research illustrates how there are positive outcomes for this topic. Occupational therapists questioning the idea of rehabilitation services for hand therapy can read this study, and then formulate their own opinions based on the findings of Sampaio and other researchers. Another research titled named Disabilities of the arm, shoulder, and hand (DASH): Factor analysis of the version adapted to Portuguese/Brazil by Cheng, Sampaio, Mancini, Fonseca, and Cotta (2008) also has a focus on upper extremity disabilities. DASH has been used in a practical setting, and has been converted into other languages for the enrichment of shared research (Cheng et al., 2008). The purpose of this study was To investigate the psychometric properties (construct and discriminate validities) of the translated and validated version of DASH in the Portuguese language (Cheng et al., 2008, p. 1901). Since this is the first performance of the Brazilian DASH: Another aspect to be considered is that this is the first study to analyze the performance of the items in the Brazilian version of the instrument, which along with the scarcity of the studies that investigate performance of the instrument items, hinders comparisons (Cheng et al., 2008, p. 1908). Seeing how Brazil is now implementing the method of DASH shows that they are trying to expand their knowledge. Brazil is teaming up with other countries to utilize research. Since occupational therapists might be facilitating treatment to persons with upper extremity disabilities, constructing research for this problem in this country is important. Due to the fact that Brazil has strong manufacturing, agriculture, mining, and service sector (Frumkin Ca^mara, 1991, p. 1619), the need for DASH and occupational therapy could effectively help the disabled workers. One article describes the application of a model for analyzing industrial tasks that was developed to identify jobs that could potentially be filled by people with disabilities (DP) and to serve as a guideline for a company hiring policy (Simonelli Camarotto (2008), p. 150). Analysis of industrial tasks as a tool for the inclusion of people with disabilities in the work market is the name of the article (Simonelli Camarotto, 2008, p. 150). This model could be used in other countries where seen fit. In the countries where disabled people want to work, a model would be a good foundation to restart employment. A survey conducted in 1997 by the United Nations Scientific and Cultural Organization found that 10% of the worlds population has some form of disability (Simonelli Camarotto, 2008, p. 151). Brazil has approximately 20 million people who are disabled according to the World Health Organization (WHO, 1996). However, only 2% of the DP have a routine job. Brazil contributed this r esearch on the basis that in Brazil, Law No 8213/91 makes it obligatory to hire DP based on the quotas that are established according to the number of employees in a public and private company (Simonelli Camarotto, 2008, p. 150). The model consists of three stages: analysis of the task, study of the activity and description of the jobs indicated for DP. Each job involves a set of tasks that can be subdivided into stages or subtasks (Simonelli Camarotto, 2008, p. 153). In the realm of occupational therapy this research will use a set of methods and techniques based on the ergonomic work analysis and on occupational therapy, we sought to build a model to indicate the skills required to perform industrial tasks (Simonelli Camarotto, 2008, p. 150). The model was applied at 19 workstations at a Brazilian aircraft manufacture in 2002 (Simonelli Camarotto, 2008, p. 150). Occupational therapy patients wanting to get back in the workforce could possibly perform this model (Simonelli Camarotto, 2008). The model would then serve as a guide in the companys policy for hiring DP (Simonelli Camarotto, 2008, p. 153). By Brazil conducting this research and developing this model, occupational therapists can try to get the ir patients back to work across the world. In addition, if the model shows independence for their particular patient they can show their evidence to the employer. Based on additional research found children are another focus of Brazilian exploration. For example, the article The implications of Winnicotts theory of play for the work of occupational therapys observation with children with physical disabilities demonstrates that play is an activity that reveals personal aspects of the person engaging in it; and play experiences embody aspects of the subjects internal reality, according to D. W. Winnicotts theory (Takatori Bemtempo, 2007, p. 47). This study brings the idea of evaluating the disabled child in their home. There were three children that participated in the study. All three of the children had a physical disability. The goal of this study was to show how important it is to observe a child. This study demonstrates that if an occupational therapist can observe and see how a child plays, they can in turn make progress with the disabled child. One article conveyed that it is the concept of play that we use to understand the person with disabilities, his/her activities and his/her social participation (Takatori Bemtempo, 2007, p.50). With this being said play observation can be put into practice in unique therapy sessions. The focus of occupational therapy in Brazil appears to be on disabilities based on the research found. However, this does not mean it is the most popular, most important, or most well-known. Brazil is in the process of making their research more assessable to people of other countries (Barreto Barata, 2008). In addition: Brazil is the only Portuguese-speaking country that has a network of scientific journals in public health/epidemiology. As to the languages papers published, these journals usually publish in Portuguese, English, or Spanish, although most of the papers are published in Portuguese (Barreto Barata, 2008). This is a mature step in the right direction for Brazil. Putting their research out there for other countries to use is not only good for occupational therapy, but for all other health care fields. Moving the body of research forward in Brazil will only enhance knowledge of their country and other countries.
