Case 1 FedEx Corporation Study Example | Topics and Well Written Essays - 250 words - 1

1 FedEx Corporation - Case Study Example The company is facing a big problem of culture diversification. Most of the employees come from different countries and hence have different backgrounds. It is hard to meet their culturally demands and hence it becomes a problem in managing them. The company solves the problem of culture barrier by learning different cultures of people. Learning different cultures of people help in understanding them well and hence avoid work conflicts. FedEx offers training to employees in order to improve their working efficiency (Anthony & Perrewe, 2010). FedEx has a good paperless system of storing data of its employees. They have programs called PRISM HIRS which records any information pertaining to a worker. This programs record jobs posting, applicants and training information. It is important to maintain this strategy because information can never be lost. Information stored in files is mostly misplaced. There is also communication where employees airs their grievances and make suggestions. This should be maintained because it boosts the morale of

Three Essential Qualities of Leadership Essay Example for Free

Three Essential Qualities of Leadership Essay What is a leader? According to Kouzes and Posner, leadership is â€Å"the art of mobilizing others to want to struggle for a shared aspiration†, and indeed, these men go further to posit that leadership transcends a certain mode of behavior, rather, that it is an active set of skills and qualities that is clearly apparent. (Kouzes Posner, 2012) An essential quality then, is a quality in leader that is necessary to achieving the goal of inspiring subordinates to said struggle. This essay will attempt to identify the three essential qualities of leadership from a stimulus, namely an episode of Undercover Boss. The three essential qualities that can be extrapolated from the film are competency, charisma and consistency, as these skills have been shown to inspire colleagues to action and breed trust between the leader and his or her charges, which is key to successful communication (Bordum, 2005) which is the foundation for the execution of the former. Competency in leaders gives the leader credibility in the eyes of his subordinates, which in turn inspires confidence in and thus a willingness to submit to said leader’s leadership. We examine this phenomenon through the example of Walter, a day manager at Waste Management. Although Walter suffers from a crippling ailment that requires him to be under dialysis a large part of the week, Walter is still able to carry out his job well, making him a role model for his new recruit, whom his story inspired to at least try to do better. In today’s modern and increasingly liberal world, leaders are no longer conferred their title through blood relations or rank. In today’s world, a leader must live up to the expectation of the people he leads- he or she must make sure his subordinates actively want to submit to his or her leadership. (Kouzes Posner, 2011) The foundation of the leader- subordinate relationship is credibility, which creates trust in the leader and which is key to inspiring subordinates to action. (Bordum, 2005) Walter’s extreme proficiency even in the face of his handicap is a display of his merit, that his leadership position was well deserved, thus breeding in his subordinates a willingness to struggle for a shared aspiration, thus making competency an essential quality of leadership. Next, consistency in leaders breeds trust in the leader, which goes towards maintaining the credibility gained from competency (as we have discussed in the previous paragraph) and thus, while it does not actively serve to gain credibility or inspire on its own, but rather helps maintain the level of credibility created through the leader’s skill set. We examine the example of Jaclyn, another manager at Waste Management. Due to downsizing in the company, Jaclyn is made to juggle the workloads of multiple jobs, and is underpaid and struggling to pay her taxes. Despite her many woes, Jaclyn still keeps up a positive attitude, and consistently performs her tasks well, earning her respect and credibility in her subordinates. It is a common adage that succeeding once is easy, but doing it consistently, is much more difficult. As mentioned earlier, leaders are being judged by their subordinates, who hold their leaders to high expectations, which are to be fulfilled consistently. Should the leader disappoint in this respect, the leader loses his or her credibility (Kouzes and Posner, 2011) However, a leader that consistently lives up to the standards is a leader that will actively maintain if not increase her credibility, as consistent competency inspires trust in said leader’s subordinates (Whipple, 2002) , in turn creating credibility, and as discussed in the former paragraph, this credibility goes towards inspiring others into the struggle for the shared aspiration. Jaclyn’s consistency in her performance, in the face of difficulty looming over her, grants her trust in her subordinates, thus allowing her to mobilize them towards their shared aspiration. Hence we see how consistency links into the maintenance of a leader’s credibility, allowing the leader to continue mobilizing subordinates towards a common goal. Finally, charisma is an important quality of leadership as it helps a leader communicate an aspiration to the group and influences subordinates to want to partake in the aspiration, thus creating the shared aspiration. For example, a manager that supervises the cleaning of portable toilets for Waste Management uses this charisma to help his subordinate find the job fun. Charisma is an important part of leadership as charismatic leaders are emotionally expressive, eloquent, charming (House, Spangler and Woycke, 1991) and are thus able to communicate a goal to their subordinates and persuade them to sacrifice personal aspirations to partake in a common goal, mobilizing them toward a shared aspiration (Fiske, Gilbert and Lindzey, 2010) In the example, the manager was able to communicate the objective of cleaning toilets, but uses his charisma in order to win over his subordinate, and allow them to share the objective of cleaning out the toilets. Thus we see how central charisma is in generating the shared aspiration in the first place, and in conjunction with the two qualities mentioned previously, help encourage and mobilize subordinates to action, thus making it a quality essential to leadership The three skills of consistency, competency and charisma are thus important- essential, if you will- qualities for being a good leader, and inspiring one’s colleagues into action towards a common objective References: Bordum, A.

Water and power consumption: Analysis of sewage treatment plant

Water and power consumption: Analysis of sewage treatment plant 1. INTRODUCTION: Waters unique Characteristics and its essential Role for all life have inspired myths and influenced cultures, religions, art, and literature through all times. The process involved for the RBC Biological Treatment method is named as FIXED FILM ROTATING BIOLOGICAL CONTACTOR BIOWHEELS. In this process by means of rotation of the bio wheels micro organisms are expected to growth in the RBC and the overflow from the Lamella clarifier will be the first stage of the treated water. The micro organisms will develop on the surface of the disk and the colonization of the organisms will take place because of the inlet load into the system. The thick film like formation in the surface of the disk is the indication of the growth. In Sewage water the main constituents of Pollutants being organic in nature these can be digested easily in the RBC. Sewage is created by institutions, residences, and hospitals and commercial and industrial establishments. Raw influent of sewage wastewater includes household waste liquid from the toilets, sinks, showers, kitchens, baths, and so forth that is disposed of sewage waste water. 1.1 Aim: The aim of the project is to Analysis of water consumption and power consumption of sewage treatment plant. 1.2 Objective: * To Analysis the water and power consumption of the sewage treatment plant * To vary the parameters of water source, power source. * To Analyze the Rotating Biological contactor Biowheels.Lamella clarifier * Analyzing 2D design of the Sewage Treatment Plant. * To analyze the results and propose appropriate solution. 2. BACKGROUND RESEARCH: Waste water collected from domestic and industrial communities must be returned to receiving waters or to the land. Although the collecting of storm water and drainage dates from ancient times the collection of waste water can be traced only to the early 1800s. The systematic treatment of wastewater followed in the late 1800s and early 1900s. There are many methods and processes to treat wastewater. The most common approach uses primary treatment (screening and clarification) to remove solids; aerobic, suspended growth, activated sludge secondary treatment to reduce organic pollutants; and chlorine disinfection to reduce pathogens. Secondary treatment is the largest energy consumer (30 to 60% of total plant usage), followed by pumping and sludge processing. Although suspended growth, activated sludge is the most common wastewater treatment process, it is not the most energy efficient. Aerated lagoons, trickling filters and rotating biological contactors are significantly more efficient. They are not as widely used because aerated lagoons require a large land area, and trickling filters and rotating biological contactors are better suited for smaller capacity applications. Many wastewater treatment plants are shifting from chlorine-based disinfection to UV disinfection to eliminate the risk of storage and handling of toxic chemicals. Although UV disinfection is energy intensive, it adds no chemical residue to the effluent. This feature is particularly important for discharge to sensitive aquatic environments or for wastewater reuse. In general, low pressure UV systems are substantially more efficient than medium pressure systems. Energy efficiency opportunities in wastewater treatment include the use of fine bubble diffusers, dissolved oxygen control of aeration, high efficiency blowers, variable frequency drives on pumps and blowers, premium efficiency motors, and the reduction of the head against which pumps and blowers operate. Sewage is generally a mixture of domestic of waste water from bath, sinks and washing machines and toilets, waste water from all industry and rainwater runoff from roads and other surfaced areas. Every day in the UK about 347,000 Kilometers of sewers collect over 11 Billion liters of waste water. This is treated about 9000 sewage treatment works before the treated effluent is discharged to inland waters, estuaries and the sea. Without suitable treatment, the waste water we produce every day would damage the water environmental and creates to affect the public health problems. Untreated sewage contains organic matter carbohydrates, fats and proteins, bacteria and chemicals. Bacteria naturally present in environmental waters do break these substances down, but in doing so they use the oxygen dissolved in this water. If there were large or continuous untreated discharges of urban waste water the result could be too little oxygen for fish and other aquatic life to survive. So the purpose of waste water treatment is to remove organic substances to protect the environment from these effects. Sewage works therefore reproduce what would be occurring in the environmental. Settling out much of the solid matter is called Primary Treatment, and using Bacteria that digest and break down the organic substances is called Secondary Treatment. Sometimes further treatment Tertiary is required to protect sensitive water environments; Tertiary treatment can involve disinfecting the treated effluent to protect the bathing and shellfish waters. It can also involve the removal of phosphorous or nitrates nutrients present in sewage. To protect the waters that is threatened by eutrophication. (ref sewage treatment in the UK defray department for environment food Rural affairs,PB 6655 March 2002.). 3. LITERATURE REVIEW: Municipal water use is generally divided into four categories, 1. Domestic water normally used for sanitary and general purposes 2. Industrial water used for nondomestic purposes, 3. The Public service water normally used for fir fighting, and system maintenance and also municipal landscape irrigation. 4. Unaccounted for system losses and leakage The following data are typical municipal water use in the United States Report. ( (George Tchobanoglous and Franklin L. Burton, 1991) Table 1 Municipalities water use 3.1 Domestic water use:. Domestic water use encompasses the water supplied to residential areas ,and commercial districts, institutional facilities, and recreational facilities as a measured by individual water meters .The uses to which this water is put include drinking, washing, bathing, culinary, and waste removal, and yard watering these kind of water collected from household sewage. Using the average flow values reported in above table of the water used in a municipal water supply system is for domestic purposes. 3.2 Residential areas: The water normally used by residential households consists of water for interior use such as showers and toilets and water for exterior use such as lawn watering and car washing, the household wastewater mostly used in sewage treatment plant. Typical data for interior water use are presented in below table. How much amount of water used in residential areas water use for exterior applications varies widely depending upon the geographic location, climate and time of year and mainly consists of landscape irrigation. The Residential areas 100% of water normally used by typical distribution of residential interior water use the following table given details Table 2 Typical distribution interior water use (George Tchobanoglous and Franklin L. Burton, 1991) 3.3 Commercial facilities: The water used by commercial facilities for sanitary purposes will vary widely depending on the type of activity means example of offices and compared to a restaurant. Typical water use values for various types of commercial facilities are reported in following table also for large commercial water using facilities such as laundries and car washes, careful estimates of actual water use should be made. Table 3 Typical rates of water use for commercial facilities (George Tchobanoglous and Franklin L. Burton, 1991) 3.4 Institutional facilities: Water used by facilities such as hospitals, schools and rest home is usually based on some measure of the size of the facility and the type of housing function provided example of per student or per bed, and water normally use for schools will vary significantly depending on whether the students are housed on campus or are day students. The representative water use values for institutional facilities are reported following table. Table 4 Typical water-use values for institutional facilities (George Tchobanoglous and Franklin L. Burton, 1991) 3.5 Recreational Facilities: The recreational facilities mostly water used in such as swimming pools, bowling alleys, and camps, resorts, then country clubs perform a wide range of functions involving water use. The following table typical water use values are reported. Table: Typical water-use values for recreational facilities (George Tchobanoglous and Franklin L. Burton, 1991) 4. SEWAGE TREATMENT PLANT: 4.1PRINCIPLE: Sewage treatment plant there are two main types of biological reaction, depending upon the presence or absence of free oxygen, the aerobic reaction takes place only in the presence of free oxygen and produces stable, relatively inert end products. Anaerobic reaction are more complex, being two stage, proceeding relatively slowly and leading to end products which are unstable and which still contain considerable amounts of energy. In any biological reaction the energy in the organic matter, used as food by the microorganisms, is split three ways; some is used in creating new microorganisms, some is incorporated in the end products of the reaction, the proportions of energy in the three areas depend upon the nature of the reaction, the type of organic matter, the type of microorganisms,and environmental conditions. The organic matter in wastewater thus provides the well as providing the energy for the oxidation reactions which releases the end products of biological treatment. (THY Teb butt,1990). Domestic sewage satisfies all these requirements but some industrial wastewaters may be lacking in nutrients or other factors, which could result in inhibition of biological activity, Toxic substances present in the wastewater can also mean that biological treatment of an organic wastewater is ineffective, although it is sometimes possible for microorganisms to become acclimated to substances which initially appear to be toxic. The aim of conventional biological treatment processes is to achieve almost complete removal of the organic matter in the feed. The activated sludge system is a common form of dispersed growth reactor, and both systems require a settling facility to remove the excess biological solids produced in the process. In the case of fixed film systems the solids are essentially dead cells, but with the dispersed growth activated sludge systems the bulk of the cells are living and are returned to the reactor for re use, only the excess solids being removed. (THY Tebbut t,1990). Characterstics of waste water sewage treatment plant:  · Bio chemical oxygen demand  · Total dissolved solids  · Chemical oxygen demand  · Total suspended solids  · PH  · Bio chemical oxygen demand: It is a measure of the amount of oxygen that bacteria will consume while decomposing organic matter under aerobic conditions.  · Total dissolved solids: It comprises inorganic salts and small amounts of organic matter that are dissolved in water. The principle constituents are usually the captions , calcium, magnesium, sodium, and potassium and the anions carbonate, bicarbonate, chloride, sulphate and particularly in groundwater nitrate.  · Chemical oxygen demand: It is a measure of the total quantity of oxygen required to oxidize all organic material into carbon dioxide and water. * Total suspended solids: It is a measure of the suspended solids in waste water, effluent, or water bodies determined by tests for Total suspended non-filterable solids.  · PH: It is a measure of the acidity or alkalinity of a solution numerically equal to 7 for neutral solutions increasing with increasing alkalinity and decreasing with increasing acidity. The PH scale commonly in use ranges from 0 to 14. ( www.answers.com ) Classification of Waste Water Treatment Methods The wastewater treatment is contaminants are removed by physical, chemical and also biological methods. Sewage Treatment Plant individual methods usually are classified as a physical unit operations, chemical unit operations and also Biological unit operations and processes. Although these operations and processes occur in a variety of combinations in Treatment Systems. (George Tchobanoglous, FranKlin L.Burton, 1991,1979,1972) 4.2 Physical operations unit: The Treatment methods in which the application of physical forces to predominate are known as physical operation unit. Because most of these methods involved directly from the first observations of a nature, and they were the first to be used for wastewater .treatment. These are the Screening, Mixing, Flocculation, Flotation,sedimentation,Filtration,and Gas transfer are typical unit operations. (George Tchobanoglous, FranKlin L.Burton, 1991,1979,1972). Screening: The first off all unit operation entered in wastewater treatment plants is screening .a screen is a device with openings ,generally of uniform a size, that is using to retain the coarse solids found in wastewater. Description: The screening elements may consists of parallel bars, wires or ,grating, rods, mesh, or perforated plate ,a screen composed of parallel bars or rods is called a bar rack sometimes called a bar screen). The term screen is used for screening devices consisting of perforated plates wedges wire elements and wire cloth. The materials removed by these devices are known as screenings. Bar Racks: In Wastewater treatment, bar racks are used to protect the Pumps pipelines valves and other appurtenances from the damaged or clogging by a rags and large objects. Screens: Sewage treatment plant is widely used to Barscreening,early screens were of the inclined disk or drum type, whose screening media consisted of bronze or copper plates with milled slots ,and were installed in place of sedimentation tanks for primary treatment .since the early 1970s,there has been resurgence of interest in the field of wastewater treatment in the use of screens of all types ,the application range from primary treatment to the removal of the residual suspended solids from biological treatment processes. (George Tchobanoglous, FranKlin L.Burton, 1991,1979,1972) Mixing: Mixing is an important unit operation in many phases of wastewater treatment including (1)the mixing of one substances completely with another, (2)the mixing of liquid suspensions,(3)the blending of miscible liquids,(4)flocculation and (5)heat transfer .chemicals are also mixed with sludge to improve tidal watering characteristics. In anaerobic digestion, mixing is used accelerate the biological conversion process and to heat the contents of the digester uniformly . Description Apparatus: Most mixing operations in wastewater can be classified as continuous rapid or continuous. Continuous -rapid mixing is used most often where one substance is to be mixed with another. Continuous mixing is used where the contents of reactor or holding tank or basin must be kept in suspension. Energy dissipation mixing: The power input per unit volume of liquid can be used as a rough measure of mixing effectiveness, based on the reasoning that more input power creates greater turbulance,and greater turbulence leads to better mixing. Sedimentation:: It is one of the most widely used in waste water treatment, sedimentation is the separation from the water, by gravitational settling, of suspended solids that are heavier than water, it is one of the most widely used unit operations in wastewater treatment .A Sedimentation basin may also be referred to as a sedimentation tank, settling basin ,or settling tank, Sedimentation is used for grit removal, particularly floating matter removal in the primary settling basin, biological float removal in the activated sludge and settling basin and chemical flog removal. Whenever the chemical coagulation processes is used. 4.3 Chemical unit processes: Sewage treatment plant is widely used to chemical unit processes ,This Treatment Methods in which the removal or conversion of the contaminants is brought about by the chemicals or by other chemical reactions are known as a chemical processes unit. There are three different types chemical processes used in the wastewater treatment.Precipitation,and disinfection and adsorption, which the process mostly used in the wastewater treatment. In the chemical precipitation ,treatment is also accomplished by producing a chemical precipitate that will settle. In most cases the settled precipitate will contain the both constituents that may have reacted with the adding to chemicals and the substance that were swept of wastewater as the predicated settled in the water. (George Tchobanoglous, FranKlin L.Burton, 1991,1979,1972) 4.4 Chemical coagulation: The settlement of fine colloidal and suspended solids can be assisted by the use of flocculation as but with dilute suspensions, such as lowland river waters, the opportunities for collisions and agglomeration are limited. In such circumstances flocculation does not significantly improve the settling characteristics of the suspension. the addition of a chemical coagulant, which precipitates flocculent solids in the water, followed by flocculation and sedimentation, can provide a high degree of clarification. the processes of chemical coagulation is thus carried out in a sequence of operations, the first of which involves rapid to permit enmeshment of the colloidal solids in the rapidly precipitating flock. (THY Tebbutt, 1990) Following the initial stage precipitation stage, the suspension is passed to flocculation and sedimentation units, which may be separate or combined. the most popular coagulant for potable water treatment is aluminum sulphate, often referred to as alum. When it is added to water in small doses of around 20-50mg/l,a reaction takes place with the natural alkalinity present, and insoluble aluminum hydroxide is formed. this responds well to controlled flocculation. The chemical reactions which occur are complex but may be simplified as Al2(SO4)3 +3Ca(HCO3)2 = 2Al(OH)3 + 3CaSo4 +6CO2 When using the commercial alum which has 16-18 molecules of water of crystallization, and expressing alkalinity in terms of calcium carbonate, each mg/l of alum reacts with 0.5mg/l of alkalinity. By using a range of coagulant does and PH values ,it is possible to determine the optimum conditions to achieve the required water quality. (THY Tebbutt, 1990) Chemical precipitation: In essence ,chemical precipitation depends upon the use of an added reagent which combines with the impurity to be removed to give an insoluble product which can then be removed by sedimentation, preceded by flocculation if necessary. A(impurity) + B(reagent) = C (precipitate) + D(by product) It is clearly essential that any byproduct of the reaction does not itself have undesirable properties in relation to the eventual use of the water or wastewater. It is also important to remember that chemical precipitation processes produce sludges containing the impurities and that the cost of handling and disposing of these sludges in a safe manner can be significant. (THY Tebbutt, 1990) Disinfection: Disinfection refers to the selective destroy of disease causing organism .all the organisms are not destroyed of during the process; this differentiates disinfection from sterilization, which is the destruction of all organisms. In the field of waste water treatment, there are three categories of human enteric organisms of the greatest consequence in producing disease are viruses, bacteria, and amoebic cysts. Disinfection is widely used to wastewater sewage treatment plant; there are well -established links between the contamination of drinking water with facial matter and the incidence of such water related diseases as cholera, typhoid and many gastrointestinal infections. Thus the removal of the pathogenic microorganisms from water supplies is a very valuable measure for the improvement of public health. Disinfection means the destruction of pathogenic microorganisms and does not necessarily mean that the water is sterile, since a small number of harmless microorganisms are usually present in tap water and poses no hazard. For most disinfection the rate of kill is given by dN/dt = -KN where k = rate constant N = number of living microorganisms The rate constant varies with the particular disinfectant, its concentration, the organism being killed,PH,Temperature,and other environmental factors. (THY Tebbutt, 1990) 5. Biological unit processes: Sewage Treatment plant is widely used to Biological unit processes ,this is processes is remove the microorganism of the water, In this Treatment methods in which the removal of contaminants is bring about by biological activity are known as a biological unit processes. Biological treatment is used primary to remove the biodegradable organic substances matter (means colloidal or dissolved )in wastewater.Basically,these substances matter are converted into the gases that can be escaped to the atmosphere and into the biological cell tissue unit that can be removed by settling. At the same time this treatment is also used to remove the nutrients (means nitrogen and phosphorous) in wastewater. (George Tchobanoglous, FranKlin L.Burton, 1991,1979,1972) 5.1 Components of wastewater Flows The components of the wastewater flows that make up the wastewater flow from a community depend on the type of collection system used and may include the following: There are four types of wastewater flows available in the wastewater treatment. 1. Domestic (is also called sanitary) wastewater. This is kind of wastewater discharged from residences and from commercial,instutional , and house hold sewage toilet waste water, bath, sinks ,and canteen wastewater and similar facilities. 2. Industrial wastewater .this kind of wastewater in which industrial wastes predominate. 3. Infiltration/inflow .water that enters the sewer system through the indirect and direct means. The Infiltration is extraneous water enters that the sewer system through the leaking joints. 4. Storm water. Runoff resulting from rainfall and snowmelt. This kind of components of wastewater flows essentially used in the sewage treatment plant. 5.2 Waste water treatment: There are four different types of wastewater processing in available in sewage treatment plant. Primary treatment referred to physical unit operations. Secondary treatment referred to chemical and Biological unit process, and also Advanced or tertiary referred to combinations of all four other processing.  · Preliminary wastewater treatment: Preliminary wastewater treatment is defined as the removal of wastewater constituents that may causes to maintenance of the operational problems with the treatment of the operations. Examples of preliminary operations are screening and commutation for the removal of debris (J.Staudenmann, A. Schonborn, C. Etnier, 1996).primary wastewater treatment: In primary wastewater treatment, a portion of the suspended solids and organic material is removing from the waste water. This removal is usually accomplished with physical operations such as screening and sedimentation. The effluent from primary treatment will ordinarily contain considerable organic matter and will have relatively high BOD.treatment plants using only primary treatment will be phased out in the future as implementation of the EPA secondary treatment requirements is completed. Rare instances (for those communities having a secondary treatment waiver)will primary treatment be used as the sole method of treatment .the principal function of primary treatment will continue to be as a precursor to secondary treatment . * Conventional secondary wastewater treatment: The secondary treatment is directed principally toward the removal of bio degradable organics and suspended. Disinfection is included frequently in the definition of conventional secondary treatment is defined as the combination of processes customarily used for the removal of these constituents and includes biological treatment by activated sludge fixed film reactors, or lagoon systems and sedimentation.  · Advanced wastewater treatment/wastewater reclamation: Advanced wastewater treatment is defined as the level of treatment required beyond conventional secondary treatment to removing constituents of concern including toxic, nutrients, compounds, and larger amounts of organic material and suspended solids .In addition to the nutrient removal processes, unit operations or processes frequently employed in advanced wastewater treatment are chemical coagulation, flocculation, and sedimentation followed by filtration and multi grade filter and also activated carbon filter. (George Tchobanoglous, FranKlin L.Burton, 1991,1979,1972). 6. STP BASED ROTATING BIOLOGICAL CONTACTORS: 6.2 Principle: A Rotating biological contactor (RBC) is constructed of bundles of plastic packing attached radically to a shaft, forming a cylinder of media .the shaft is placed contour bottomed tank so that the media are submerged approximately 40 percent. the contactor surfaces are spaced so that during submergence in wastewater can enter the voids in the packing .when rotated out of the tank ,the liquid trickles out of the voids in the packing. when rotated out of the tank the liquid trickles out of the voids between surfaces and is replaced by air. A fixed film biological growth, similar to that on a trickling filter packing, adheres to the media surfaces. Alternating exposure to organics in the wastewater and oxygen in the air during rotation distributor. Excess the biomass sloughs from the media and is carried out in the processes effluent for gravity separation. A treatment system consists of primary sedimentation preceding and final sedimentation following the rotating biological contactors. Since the recirculation through RBC units is not normally practiced, only sufficient underflow from the final clarifier is returned to allow removal of excess of the biological solids in primary sedimentation and waste sludge similar to the character to the from trickling filter plant ,in withdrawn from the primary clarifiers disposal of waste. In large type of plants, a common shaft is placed over a contoured tank with the wastewater flow parallel to the shaft. A series of four stages are normally installed in the treatment of domestic wastewater for BOD reduction. additional stages may be added to initiate nitrification .Each stage acts as a completely mixed chamber and the movement of the wastewater through the series of tanks simulates plug flow. Biological solids washed off of the media are transported hydraulically under the baffles to be carried out with the effluent.RBC units are protected by installation either in a building with adequate ventilation or under separate plastic covers lined with insulation. The efficiency of BOD removal of in the processing domestic wastewater is based on empirical data from operating RBC plants. the Mathematical equations also have been developed ,but their prediction of the performance is not consistently reliable. the typically recommendations for secondary treatment of domestic wastewater to produce an effluent of less than 30 mg/l of BOD and also 30mg/l of suspended solids.

ROTATING BIOLOGICAL CONTACTOR PROCESS(60 KILO LITRE PER DAY): 2D 8. WATER CONSUMPTION ANALYSIS OF SEWAGE TREATMENT PLANT: Raw sewage characteristics: Domestic waste water: The volume of a wastewater from a community varies from 50 to 250 gal capital per day depending on the sewer system uses. A common values for domestic wastewater flow is 120 gpcd means 450 liter person per day use, which assumes that the residential waste water have modern water using appliances, such as automatic washing machines. the organic substances matter contributed per person per day in domestic wastewater is approximately 0.24 lb to 110gram of suspended solids and 0.20lb and 90 gram of BOD in communities where a substantial portion of the household kitchen wastes is designed is discharged to the sewer system through garbage grinders. In selection of data for design, the quantity of and organic strength of wastewater should be based on actual measurements taken through the year to account for variations resulting from seasonal climatic changes and other factors. the average values during the peak month may be used for design ,excluding un usual infiltration and inflow, the av erage daily sanitary wastewater flow during the maximum month of the year is commonly 20 to 30 percent greater than the average annual daily flow, excluding seasonal industrial wastes, the average daily BOD load from sanitary wastewater during the maximum month is greater than the annual ave

An Investigation Into The Rate of Reaction of The Catalase Enzyme :: Papers

An Investigation Into The Rate of Reaction of The Catalase Enzyme Introduction: In this experiment I will attempt to investigate the factors that effect the rate of reaction of the catalyse enzyme. Catalyse is an enzyme found in food such as potato and liver. It is used for removing hydrogen peroxide because of the shape of the hydrogen peroxide molecule; this type of reaction is when a molecule Is broken down into smaller pieces called catabolic reaction. Enzymes are proteins e.g. catalyse. They are made in cells. A catalyst is something that speeds up a reaction. One molecule can usually be used many times. All enzymes work at different pHs because they have different jobs to do but you cant use a ph which isn't suitable for that particular enzyme which you are using, other wise the enzyme will de nature. Enzymes also react with tempreture but like the ph the temperature cant be unsuitable to the enzyme other wise it will de nature or slow down the enzymes which would make it very difficult to obtain accurate and reliable results. A carbohydrase enzyme is different to a catalyse enzyme and other enzymes because enzymes have different patterns (shape). Enzymes are like keys to different substrates like e.g. fat, sugar and the substrates are like keyholes.

Lenin had a greater impact on Russia’s economy and society than any other Ruler. How far do you agree with this view of the period from 1855 to 1964? Essay

Lenin had a greater impact on Russia’s economy and society than any other Ruler. How far do you agree with this view of the period from 1855 to 1964? Over the period from 1855 to 1964, Russia saw various reforms and policies under the Tsars and the Communist leaders that had great impacts on its economy and society both positive and negative. Lenin definitely implanted polices that changed society and the economy for example with war communism. However whether his policies had the greatest impact is debatable and in this essay I will be assessing the view whether Lenin had the greatest impact on Russia’s economy and society than any other ruler between the period from 1855-1964. The Russia economy in terms of industry fluctuated over the period from 1855-1964. It is key to note that under all the leaders, industrialisation and modernisation was always seen as an essential economic aim. Under Alexander II, with Reutern as his Minister of finance who adopted an approach t hat revolved around continued railway construction, attraction of foreign expertise and foreign investment capital. As a result modernisation and expansion occurred within the staples as well as newer industries which show the impact that alexander II made on industry. Reutern achieved a sevenfold increase in the amount of railway and the capacity of railway to carry break bulk at speed increased which gave a major boost to industrial output Russia seemed to be finally moving towards industrialisation and keeping up with the West. This approach was similar under Nicolas II who also managed to have a great impact on Russia’s industrial economy. This was through the work of Sergei Witte whom at the time of his appointment the Russian economy still resolved predominantly around agricultural production further showing that under Alexander II impacts was limited. Witte continued the idea of foreign expertise as well as taking out foreign loans, raising taxes and interest rates to boost available capital for investment in industry. Another major development was the placement of the rouble on the gold standard in 1897. The impacts of Witte’s policies were great. Coal production doubled and that of iron and steel increased sevenfold while the total amount of railway track opened rose from 29,183 km to 52,612 km in 1901. Much of this stimulated the stupendous growth in capital abroad. There was an indication that income started to even catch up with other industrialised nations seen and income  earned from industry rose from 42 million to 161 roubles by 1897. This period of industrial success has even been named the ‘Great Spurt’ and the increase in industrial production of 7.5% far exceeded Russian achievement for any comparable period before 1914 which shows that Nicholas II had the greatest impact on the industrial economy than any other Tsar. This focus on heavy industry was continued under Stalin who implanted his five year plans; industrialisation was to be stimulated through the settin g production targets. The effects were great increase in industrial output which hard to state specifically as much of the production figures were falsified. Khrushchev mostly continued Stain’s centralisation with greater diversion as he wanted to produce more consumer goods. There was however a slowdown in growth under Khrushchev but it wasn’t a huge impact and illustrates a negative impact. This however didn’t compare to negative impacts seen under Lenin. By November 1917 Lenin stated implemented War Communism by introducing state capitalism. This involved the state taking complete control over the economy until it could ‘safely’ be handed over to the proletariat. Nationalisation by itself did nothing to increase production; military needs were given priority so that resources to those industries not considered essential were denied. The situation was made more serious by the factories being deprived of manpower as a result of conscription. The problem for industry was deepened by hyperinflation. The government’s policy on continuing to print currency notes effectively destroyed the value of money and by the end of 1920 the rouble had fallen to 1 per cent of its worthin1917. Although Lenin’s NEP started to impact industry positively and indeed industrial output increased rapidly it only ever reached the level of output in 1914. Overall, the greatest positive impact on industry arguably is under Nicholas II. Industrial output over doubled under him, railway construction expanded rapidly and his policies impacted the people as well people saw living standards increase unlike under Stalin that despite growth living standards actuall y deteriorated and Russia could have seen to be on its way to true industrialisation. Whilst under Lenin it is clear that he had the greatest negative impact on the industrial economy. There was no industrial growth and Lenin only benefited through tighter control of Russia through the economy. As well as impacts on industry it is also important to consider impacts on agriculture. The issue of land ownership can be seen to  be handled differently under each leader. Alexander II, Lenin and Stalin all pursued that effectively had negative impacts on agriculture. With the emancipation of the serfs in 1861 the peasants were ‘free’ and no longer tied to the land. The impacts however were reversal. Peasants were allocated poor quality land and received less on average than they had been farming before emancipation. Furthermore peasants were forced to pay redemption dues that were higher than what they could achieve. In the end, the impacts on the peasants were they were worse off and able peasants had no incentive to produce surpluses and were reluctant to improve the land as decisions about what was to be produces and how crops were to be cultivated were decided by the village Mir, which resulted in a slight fall in grain overall. These effects however were more severe under Lenin and Stalin as they sought to increase grain production by coercion. While Lenin under War communism used grain requisitioning to forcefully collect peasant surpluses from them Stalin used collectivisation to force peasants to collaborate to produce as much food as possible. Similarly in both cases the peasants refused to conform; knowing that any surplus would be confiscated the peasant produced the barest minimum to feed themselves and their family and even less food was available for Russia. One of the greatest imp acts were the famines that occurred in 1921 under Lenin where the grain harvest produced less than half the amount gathered in 1931 and Russia had international help from countries such as the USA. However these impacts were the greatest under Stalin. The amount of bread produced fell from 250.4 (kilograms per head) in 1928 to 214.6 in 1932. The impacts of collectivisation were at its worst in 1932-32 when occurred what many people describe as a self-made national famine. Stalin’s ‘’official silence’’ of the situation meant it wasn’t addressed and thus collectivisation killed between 10-15 million peasants and failed to increase agricultural output. Though a similar devastating famine occurred under Alexander III in which he adopted the Peasant land banks to try and alleviate the impacts and encourage farming again and in fact famines occurred over Russian history its severity was the worst under Stalin. Alexander II’s attempt to pacify the peasants to increase agricultural levels was similarly adopted under Nicholas II through the reforms of Stolypin and further under Khrushchev. Stolypin’s ‘wager on the strong’ saw that in that period peasants were paying increasingly higher taxes a sign  that their new farming was producing higher profits. The provision of land backs, abolition of redemption dues and being urged to replace inefficient strip system created a wealthier group of peasants later labelled the kulaks by communist leaders signifying that Nicholas II enjoyed higher agricultural profits. The schemes for larger-scale voluntary resettlement of peasants are a continuation under Khrushchev whos e Virgin Land Campaigns encouraged the increase in the amount of land being cultivated. In 1950, 96 million acres of land were given over to the production of wheat and by 1964 this increased to 165 million acres. His policies seem to have even impacted citizens as urban dwellers started to feel that their food requirements were at last being adequately met. Thus Khrushchev can be seen to have the greatest positive impact on agriculture as the Russian people had finally felt that the food was enough for them and the amount of land and grain cultivated increased. While the greatest negative impact was prominently under Stalin, his collectivisation was met by peasant unrest and grain and livestock destruction that lead to a damning national famine. Both the Tsars and the Communist leaders had their impacts on the Russian society. Religion and the idea that the Tsar was Gods own appointed continued under all three Tsars, so there was no real impact by any on the tsars on religion as they sought to keep this religious through the aid of the Russian Orthodox Church; the Russian people truly believed that the Tsar was appointed by God and referred to him as their ‘little father’. Despite Lenin coming into power and issuing the’ decree on the separation of the church and state’ which meant that the church was no longer to have central organisation with authority over local organisations, religious teachings in schools being forbidden and the attempt to eradicate religion Peasants continued to pray and worship as their forebears had but they could no longer risk doing it so publicly. Hence showing the Tsars had a greater impact in terms of religion than the communist leaders as all their efforts to eradicate religion and enforce atheism effectively failed. Both the Tsars and the communist attempted to expand the provision of education at all levels. Alexander II is seen to make attempts that increased the number of Russians in education. In 1864 Alexander II introduced a major education reform. This had an immediate impact in the number of available school places, especially in more isolate places and raised the quality and variety of provision which  improved. Such continuation can be seen under Khrushchev who scrapped school fees and the creation of specialist academies and the spread of correspondence courses sought to increase the quality of education in Russia. Nicholas II and Stalin’s educational policies can be seen as similar in that they both impacted society similarly by raising the number of students attending school. The number of primary schools rose from 79 thousand in 1896 to 81 thousand in 1914 under Nicholas II ( work of the fourth duma) while in 1929 only 8 million pupils were attending primary school and in 1930 this rose to 18 million pupils. Furthermore under Stalin emerged the cult of personality that aimed to control all aspects of Russian life. Censorship and propaganda increased drastically under Stalin; however whether Stalin truly had an impact on the culture and the way of thinking is debatable. The applause that greeted his every appearance in public is more likely to have been a matter of prudence than o f real affection. In comparison to the leaders already mention Alexander III sought to limit university autonomy. Under him elections to the university councils were scrapped and placed by an appointment system but nevertheless universities continued to flourish. Overall although Alexander II can be seen to have stimulated educational growth participation the greatest impacts were seen under Nicholas II and Stalin which participation increased immensely. Although the Communist leaders tried to eradicate the church from society many of the Russian population remained orthodox but secretly illustrating the strong impacts the Tars had over religion. In conclusion, it can be seen that different rulers had various impacts on many parts of the economy and society. Industrially Lenin did have the greatest negative impact as the Russia didn’t see any real economic growth and saw a great famine. However under Nicholas II Russia enjoyed the great Spurt which arguably could have seen to have a greater positive impact as it even filtered to the Russian citizens that enjoyed better standards of living and many historians express that Russia was well on its way to industrialisation. Lenin again had a great negative impact on agriculture but that of Stalin was more severe and was worse on agricultural produce. Overall, though Lenin had great impacts of different aspects of life other rulers can be seen to have had a greater impact whether positive or negative and Lenin never truly managed to have a true impact on Russian society and culture though attempted.

Social Class and Inequality

Social Class and Inequality Social inequality has been defined as a conflicting status within a society with regards to the individual, property rights, and access to education, medical care, and welfare programs. Much of society’s inequality can be attributed to the class status of a particular group, which has usually been largely determined by the group’s ethnicity or race (Macionis & Gerber, 2006). The conflict perspective is an attempt to understand the group conflict that occurs by the protection of one’s status at the expense of the other.One group will resort to various means to preserve a ideal social status through socioeconomic prestige, consolidation of power (political and financial), and control of resources. In Canada, even though its impact is frequently minimized, social inequality exists, but because the majority of citizens associate exclusively with members of their own class, they are often unaware of the significant role social inequality co ntinues to play (Macionis & Gerber, 2006). An inadequate distribution of wealth remains â€Å"an important component† of Canada’s social inequities (Macionis & Gerber, 2006).Wealth can be defined as the amount of money or material items that an individual, family, or group controls and ultimately determines the status of a particular class (Macionis & Gerber, 2006). Canada’s social classes can be divided into four, and the wealth is not distributed equally between them. First, there is the predominantly Anglo upper class, in which most of the wealth has been inherited; and they comprise of approximately 3-to-5 percent of the Canadian population (Macionis & Gerber, 2006).Next, there is the middle class, which is made up of the greatest number of Canadians, nearly 50 percent with ‘upper-middle’ class subdivisions generating white-collar incomes of between $50,000 and $100,000 while the rest are earning reasonable livings in less prestigious white- col lar jobs or as skilled blue-collar laborers (Macionis & Gerber, 2006). The working class represents about 33 percent of the Canadian population, and their lower incomes leave little in the way of savings (Macionis & Gerber, 2006).Finally, there is the lower class, which is represented by about 20 percent of the population (Macionis & Gerber, 2006). Among these are the so-called working poor whose incomes alone are not sufficient enough for adequate food or shelter (Macionis & Gerber, 2006). Their living conditions are often separated from the mainstream society in concentrated ethnic or racial communities (Macionis & Gerber, 2006). The most impoverished members of this class are unable to generate any income and are completely reliant upon government welfare programs.One of the primary deciding factors as to what determines wealth, power, and social status is occupational prestige (Macionis & Gerber, 2006). For example, in Canada, physicians and lawyers continue to reside at the top of the social ladder while newspaper delivery persons or hospitality staff rank at the bottom (Macionis & Gerber, 2006). The growing disparity in income is beginning to resemble that of the United States with approximately 43. percent of the Canadian income being concentrated within the top 20 percent of social spectrum while those in the bottom 20 percent are receiving a mere 5. 2 percent of that income (Macionis & Gerber, 2006). Nearly 16 percent of Canadians were categorized as being â€Å"below the poverty line† in the mid-1990s, and every month, close to a million people rely upon food banks to feed their families (Macionis & Gerber, 2006). The income a particular class earns is determined in large part to the amount of education received, and yet in order to receive a higher education money is required.There is also a strong correlation between income and healthcare. The higher the income, the greater the number of quality medical services there are available (Macionis & Gerber, 2006). The wealthy or upper middle classes can afford specialized care that isn’t typically covered by a provinces general health care plan, thus widening the gap of equality between the social classes. Within the boundary of the Canadian border we can see the separation between ethnicity, and wealth which determines class.Studies show that predominately the British and French Canadians earn the highest levels of income whereas the Africans, certain Asian groups, Latin Americans, and Aboriginals consistently rank near the bottom (Macionis & Gerber, 2006). In recent years, there has been an increase in income inequality with the 14 percent of impoverished Canadians in the lower social classes of families headed by single mothers, female senior citizens, indigenous peoples, and the recent influx of immigrants (Reutter, Veenstra, Stewart, Raphael, Love, Makwarimba, and McMurray, 2006).Because of social exclusion, poverty is perpetuated with certain groups consistently shut out of the opportunities that might better equalize the social scales (Reutter et al, 2006). Canadian sociologist John Porter’s focused nearly entirely on power and class, his breakthrough research was published as The Vertical Mosaic: An Analysis of Social Class and Power in Canada in 1965 (Driedger, 2001).Porter explored the impact of race and ethnicity upon social mobility and noted that Canadian social history has been determined by ‘charter groups,’ mainly the English and the French situated in Ontario and Quebec, while the English were widely dispersed in both rural and urban locales, becoming increasingly urbanized as a result of industrialization and the fortunes being made, the Quebecois group was nearly exclusively rural in geography and philosophy (Driedger, 2001).Power examined how power relationships developed along social class lines and how the conflict among these charter groups influenced differences in social classes (Driedger, 2001). Acco rding to Hier & Walby (2006), Porter presented the argument that â€Å"an ‘entrance status’ is assigned to less preferred immigrant groups (particularly southern and eastern Europeans†¦ that restricts collective gains in education, income, and membership among Canada's elite† (p. 83). This entrance status was, in Porter’s view, strong enough to create a social barrier not unlike India’s caste system (Hier ; Walby, 2006).A decade later, Porter drew similar conclusions when he noted that his Canadian census job stratification study revealed, â€Å"Ethnicity serves as a deterrent to social mobility† (as cited in Driedger, 2001, p. 421). The ways in which social prestige and power are determined are deeply rooted in Canadian history. For instance, 1867’s British North America Act gave the British and the French the distinction of being a charter group that entitled them to a power, prestige (and of course wealth) that other groups wer e automatically denied unless they displayed a similar pedigree Driedger, 2001). The charter languages and cultures, though separate, would afford these members with exclusive privileges (Driedger, 2001). They would have automatic access to society, while other groups would have to battle for entrance and to secure status. Therefore, while a few managed to break through, most ethnic groups were consistently refused entrance. For this reason, they were forced to take jobs of low class status and their degree of assimilation into Canadian society would be determined by the charter members (Driedger, 2001).There is a sharp distinction between industry and finance in terms of ownership of financial resources. The bankers exert the most social control, and because they have been historically more interested in protecting their own interests, the indigenous industrialized groups have been discouraged (Panitch, 1985). Southern Ontario remains the wealthy hub of the Canada’s industri al sector, while the indigenous groups and other lower classes remain both regionally and socially isolated (Panitch, 1985).Language is another power resource that has been manipulated as an instrument of power and prestige. While the French have long been a charter of Canadian society, as in the United States, being culturally separate has not meant equality in terms of class status. In the years following World War II, the French Canadians of Quebec have sought greater independence (Driedger, 2001). Their discontent resulted in the establishment of the Royal Commission on Bilingualism and Biculturalism in 1963, which emphasized the notion of an â€Å"equal partnership† (Driedger, 2001, p. 21). Even though charter dualism is not articulated in the Canadian constitution, the Quebec provincials believed that their one-third French-speaking status along with the growing number of languages spoken by non-charter members warranted a reclassification to at the very least bilingual ism and at the most, an acknowledgement of multiculturalism that would remove existing cultural barriers and provide greater social access. These efforts have thus fall fallen short, and therefore Quebec annexation may one day become a reality.Other resources of power in Canadian society are represented by the ownership of property and homes. In Canada as in most parts of North America, homes represent wealth because of the â€Å"forced savings, investment appreciation, and protection against inflation† it represents (Gyimah, Walters, ; Phythian, 2005, p. 338). Owning a home offers â€Å"a sense of belonging† or inclusion for immigrant classes that is unlike anything else (Gyimah, Walters, ; Phythian, 2005, p. 338).But not surprisingly, Gyimah et al (2005) have discovered, â€Å"Rates of ownership have been found to vary considerably by ethnicity and immigration status† (p. 338). There is, interestingly, a structure among immigrant classes that impacts on the ac cess to these resources with the immigrants who settled in Canada earlier enjoying much higher rates of home ownership than new immigrant arrivals (Gyimah et al, 2005). The lone exception is the Hong Kong business entrepreneurs that relocated to Canada when the Chinese regained control of the area (Gyimah et al, 2005).They had accumulated enough wealth in Hong Kong to bypass traditional barriers and secure housing usually reserved for charter members. On the opposite end of the spectrum, home ownership rates are lowest among the Blacks and Aboriginal classes (Gyimah et al, 2005). According to a study Henry, Tator, Mattis, and Rees conducted in 2002, â€Å"In spite of the historical and contemporary evidence of racism as a pervasive and intractable reality in Canada †¦ itizens and institutions function in a state of collective denial† (as cited in Hier ; Walby, 2006, p. 83). Throughout the history of Canada, â€Å"institutionalized racism† has been a part of the cu ltural landscape dating back to the indentured servants and slave labor of the African and Caribbean peoples that first arrived in the seventeenth century, and continued to be oppressed for the next 200 years in the Ontario, New Brunswick, Nova Scotia, and Quebec provinces (Hier ; Walby, 2006).The fur trade justified this enslavement and the Federal Indian Act revisions of the mid-twentieth century continued to treat certain races in a subordinate manner (Hier ; Walby, 2006). Those deemed more primitive were oppressed because of social perceptions of their â€Å"savagery, inferiority, and cultural weakness† (Hier ; Walby, 2006, p. 83). Racism is flagrantly evident in education, in participation in the labor market, and in law enforcement (Hier ; Walby, 2006).When Ruck and Wortley studied the perceptions of high school students regarding school discipline through a questionnaire issued to nearly 2,000 Toronto students in grades 10 through 12, the ethnic groupings of Black/Afri can, Asian/South Asian, White European, and Other revealed that their perceptions of discipline discrimination were significantly higher than those students of White European backgrounds (Hier ; Walby, 2006). Therefore, not surprisingly, these students were more likely to drop out of school and be denied any hope of receiving a well-paying job.Lower social classes were also relegated to low-paying jobs because of purportedly lacking â€Å"‘Canadian’ work experience† and a lack of English language comprehension (Hier ; Walby, 2006, p. 83). In a 2001 study by Austin and Este, the immigrant males they interviewed reported that because the power and resources are so tightly controlled by the White Canadian majority, their foreign employment experiences were minimized and they were blocked from taking the training programs that would have improved their language proficiency (Hier ; Walby, 2006).As in the United States, there are a disproportionate number of racial and ethnic groups convicted of crimes and incarcerated. This is believed to be due to racial profiling in law enforcement that tips the scales of justice away from people of color. According to a Royal Commission survey, the majority of respondents believe police are prejudiced against Black Canadians (Hier ; Walby, 2006). Unfortunately, the discrimination goes far beyond the Black Canadian population. The Aboriginal population provides a contemporary case study that reflects the impact of racism upon social inequality of Canada.The 2001 Canadian census lists a total of 976,310 Aboriginal peoples throughout the territories and provinces (Adelson, 2005). Of those, more than 600,000 are Native Americans – referred to as First Nations – and live mostly in the provinces of Ontario, British Columbia, Alberta, Manitoba, and Saskatchewan (Adelson, 2005). The Metis group live in the western sections of these provinces and total around 292,000 (Adelson, 2005). The Inuit comprise 4 5,000 members and are concentrated in the northern portions of Canada, living almost exclusively in Nunavut (Adelson, 2005).These peoples have been the victims of racist social attitudes dating back to 1876’s Indian Act, in which colonization was officially determined through First Nations recognition status (Adelson, 2005). This affects the Native Americans and the Inuit (as a result of a 1939 amendment to the Act), but the Metis are not forced to register to achieve a â€Å"recognition of status† (Adelson, 2005, p . 45). What this means is that those Aboriginal groups that live on government controlled reserves continue to receive government services while those who decide to venture off of these reserves do not (Adelson, 2005).Those groups are deprived of the education and basic skills that would enable them to improve their status. In comparison to non-Aborigines, the Aboriginal groups often fail to complete their education at every level, which further reduces the ir opportunities (Adelson, 2005). In a 2002 study of off-reserve Aboriginals, less than half percent of these children complete the twelfth grade (Adelson, 2005). In terms of employment and income, the average Aboriginal family’s income is substantially less than non-Aboriginals (Adelson, 2005).In 1991, the average Aboriginal income was $12,800, which was about half of the income of Canada’s non-Aboriginals (Adelson, 2005). Sociologists attribute the disparities in employment and income due to ethnic discrimination in the workplace, the lack of education accorded indigenous groups, the loss of property, and the â€Å"cultural genocide† they are forced to commit if they wish to assimilate (Adelson, 2005, p. 45). This â€Å"circle of disadvantage† results in the Aboriginals being mired in poverty and forced to take low- paying migrant jobs that are often seasonal and provide nothing in the way of employment security (Adelson, 2005, p. 5). Solely on the basi s of their ethnicity, these peoples are relegated to the social periphery and are deprived of anything remotely resembling power, prestige, or wealth. In terms of their living conditions, many of the Aboriginal peoples are overcrowded, with 53 percent of the Inuit peoples and 17 percent of the Aboriginals living off-reserve living more than one person per room (Adelson, 2005). This is in comparison to 7 percent of white Canadians of European origin (Adelson, 2005).In addition, Aboriginal homes are; twice as likely to be sorely in need of major repairs; about 90 times more likely to have no access to safe water supplied by pipes; five times more likely to have no type of bathroom facilities; and ten times more likely to have a toilet that does not flush (Adelson, 2005, p. 45). The Aborigines that do not live in government housing are exposed to appalling threats to their health and hygiene resulting from inferior housing, which has adversely affected their life expectancies (Adelson, 2005).Despite their high adult mortality, the aboriginal population also has a high birth rate (Adelson, 2005). However, this also means their infant mortality rate is also higher than the national average. According to 1999 statistics, infant mortality rates were 8 out of 100 among First Nations’ peoples, which is 1. 5 times higher than the overall Canadian rate of infant mortality (Adelson, 2005). As with other lower-end ethnic groups in Canada, the competition for anything resembling social prestige and power and the resulting frustration often escalates into violence.Within the Aboriginal groups, substance abuse, physical and sexual violence, and suicides are all too Common place (Adelson, 2005). Domestic violence statistics are high, with 39 percent of this population reporting such instances (Adelson, 2005). According to the 1999 published statistics 38 percent of reported deaths between young people ages 10 to 19 are due to suicide caused by the hopelessness of povert y and lack of social power (Adelson, 2005).Although the Aboriginal groups that still live on-reserve are receiving government healthcare services, these services are not necessarily of the quality the rest of the population is getting due to the government’s inability to control First Nation treaty resources and the seemingly endless â€Å"bureaucratic maze† regarding Aboriginal healthcare policy and insufficient funding (Adelson, 2005, p. 45). Within the past three decades, there has been a notable shift in the Canadian population.While the charter groups still comprised about 50 percent of the population, numerous other non-charter groups were rapidly combining to represent about one-third of the overall population (Driedger, 2001). Immigration pattern changes that began following the Second World War are largely responsible for a greater number of Southeast Asians and Latin Americans to relocate to Canada (Driedger, 2001). By the 1980s, the number of British Canadia ns began to rapidly slip and by 2001, while the British ranked ninth in population, 73 percent of immigrant settlers were either Asian, Latin American, or African (Gyimah et al, 2005).Meanwhile, despite Canadian policymakers’ best intentions, social inequality persists because many of these immigrant classes are being denied their rightful participation in society. Although the French charter remains strong albeit geographically and culturally segregated and the British majority is floundering, the class determinants of charter membership and its perks that enable social inequality to continue are still in place.The British population decrease has in no way adversely impacted their prestigious position or political influence. English is still the dominant language and European ancestry determines esteemed class status. Unfortunately, as long as access to prestige, power, and wealth remain limited to the charter few at the expense of the multicultural many, Canada’s soc ial classes will sadly remain unequal.
