Compare Piaget and Vygotsky

Cognitive development is the term used to describe the construction of thought process, including remembering, problem solving and decision-making, from childhood through adolescence to adulthood. In this essay I will compare and contrast the theories of Piaget and Vygotsky, both of which were enormously significant contributors to the cognitive development component to/in psychology. In addition to this I will also weigh up the strengths and weaknesses of each theory and outline how they can be applied to an educational setting. At the centre of Piaget's theory is the principle that cognitive development occurs in a series of four distinct, universal stages, each characterized by increasingly sophisticated and abstract levels of thought. He believed that these stages always occur in the same order, each builds on what was learned in the previous stage and that the development resulted from two influences: maturation and interaction with environment. Although Vygotsky’s theory works along similar lines to Piaget – the belief that children were active in their learning. He focused more on the importance of social interaction and language and how they both play a fundamental influence on children’s development of understanding. Although both psychologists acknowledged that all children go through stages, they were distinguished by different styles of thinking, and approach to analysing the cognitive development process. The stages were the centre of Piaget’s theory while Vygotsky only acknowledged them in his theory. Piaget’s theory unlike Vygotsky, generalized children into age groups and ranked their abilities accordingly. For example: Piaget believed that all children that reach The concrete Operational stage (ages 7-11) have overcome centration and become decentred, they are capable of mastering the principles of classification, seriation and class inclusion. However, Vygotsky maintained the concept that if a child follows the adult's example he will gradually develop the ability to do certain tasks without help or assistance. He called the difference between what a child can do with help and what he or she can do without guidance the â€Å"zone of proximal development† (ZPD). As a result of this different approach to children, we can relate this to the reason why unlike Piaget, Vygotsky acknowledged the issue of Special Educational needs and how some children might be of the same age as their peers but find it difficult to complete the same tasks cause of other issues. Vygotsky believed that learning leads to development and that â€Å"Pushing† the child as such was to be encouraged in order to develop the potential the child can reach. On the other hand, Piaget’s theory was based on biological maturation, an understanding that intelligence is gained as a process that is developed over time. Both psychologists believed that interaction was the key to the development of the child. However, they both focused on a different interaction. Piaget acknowledged the importance of the child’s interaction with the environment whilst Vygotsky on the other hand stressed the importance of social interaction and of having someone who knows more than the child and who can help the child learn something that would be too difficult to do alone. Piaget saw the child as a scientist, he learnt things in solitary on his own, while Vygotsky saw the child as an apprentice because he learnt as a result of social collaboration. Consequently, the way that they viewed the role of the teacher in a child’s life differed. Piaget believed that the teacher was the facilitator, the one that provides the interaction in the environment. As opposed to Vygotsky’s belief that the teacher is the expert that provides the scaffolding support to children as they are learning new things. In addition to this Vygotsky believed that language was crucial for the cognitive development. He believed that the greatest advantage in development comes when we get to the stage of being able to internalise language. One of the biggest differences between these theories was that Vygotsky was able to put his theories into practice in a school setting. Unlike Piaget, who was of an academic background and didn’t apply his theories. Never the less, they both theories influenced education and empahsied the importance of assessment however Vygotsky wanted the observation of children and their abilities to be as valied as test scores. Most of the criticism of Piaget’s work is in regards to his research methods. A major source of his inspiration for the theory was based on his observations of his own children. And because of this small sample group, people believe that it is difficult and incorrect to generalise his findings to a larger population. Similarly, many psychologists believe that Piaget underestimated the age which children could accomplish certain tasks and that sometimes children understand a concept before they are able to demonstrate their understanding of it. For example, children in the Sensorimotor stage may not search for a hidden object because their motor skills are not developed, rather than because they lack object permanence. This has been supported by evidence from Bower & Wishart (1972). They found that the way that an object is made to disappear influences the child’s response. As well as this, Piaget’s theory has been said to overestimate that every child and adult reaches the formal operational stage of knowledge development. Dasen (1994) claims that only a third of adults ever reach this stage. The lack of empirical support in regards to Piaget’s suggestion that the cognitive development is built from the conflict that endures by placing the child in a state of disequilibrium was critisied by other psychologists. For example, Inhelder et al. 1974) showed that children learn better in situations of mild conflict. Also, Piaget focused on children’s mistakes and thus may have overlooked important mental abilities of the children by focusing on in what connection did they make their error during the task. Although Piaget’s theory has quite a lot of criticism, he will always be known as one of the most influential psychologists. His theory is known to have had a great contribution to education and has provided a starting point for other psychologist’s research which has helped us develop and understand the cognitive development. When compared with Piaget’s theory, a major weakness to Vygotsky’s theory is that there is little empirical research relation to it. This is probably due to his early death and because the theory focuses on the process of the cognitive development and not of the outcomes like Piaget’s. In addition to this, many psychologists believe that vygotsky might have over emphasised the influence that social interaction on children’s learning capabilities. However on the other hand, it is said that he underemphasized the biological and individual factors of the cognitive development. Vygotsky encouraged being aware of the children potential and how with the proper assistance or support from an adult or a peer with more knowledge the child is capable of learning more. Through this simple observation he gave it the term of â€Å"Zone of Proximal Development† . Hughs (1975) and Donaldson (1978) proved this by demonstrated that the same tasks that Piaget set for the children can be made understandable by making them more child friendly by providing a familiar social atmosphere. The practical application of the ideas presented by both Piaget’s and Vygotsky’s theories in a classroom could help a classroom run more smoothly by providing the teacher with different teaching methods. A teacher following Piaget's theories would be likely to group children of similar levels of development together. The teacher would encourage abstract thought during discussions, and be certain to build on previous information that the students had been given. However, when testing the skills and knowledge of the students, the teacher would be more likely to use questions that evoked concrete answers such as true or false questions. The teacher would be more likely to go over past information add new information, assign individual assignments, and then test the students' knowledge on the subject. On the other hand, a teacher following Vygotsky's theories would be more likely to form groups of diverse students with different skill levels and different levels of knowledge, possibly even setting up tutors for slower students. The teacher would be more likely to assign group projects and give the students problems to solve, as opposed to asking questions that can be answered with a concrete answer. In addition to this, the teacher should attempt to create a lesson that would incorporate all three stages of learning by providing the information to the students, allowing diverse groups to work together and then assigning an individual task that tests the students' ability to think through the information and problem on their own. Which would help prove that with the help they received before they were apable of doing the next task by themselves. Although both theories can be applied to an educational setting, their implications on a classroom would arise in different manners. By only applying Piaget’s theory in a classroom, for example grouping children of similar levels of development would produce a group of smart children and a group of less capable children. In doing this, the classroom could beco me a place where the less capable children would be known as underachievers and taunted by the more academical children. Similarly, only applying Vygotsky’s theory in an educational, for example, by forming groups of diverse students with different skill levels an different levels of knowledge together, only applying Vygotsky’s theory in an educational, the able children will always be assisting the less able and it may hinder their abilities to learn. In conclusion, I think that both Piaget’s and Vygotsky’s theories offer different insight into how children learn and that maybe by combining the different ideas from both of them would help in building a good teaching classroom.

Personal Income Expense Statement and Budget Essay

2.1Personal income statementAnnual wages$75,000 Monthly Gross pay $6250 Federal Withholding $265 Social Security $238 Medicare $56 California State $149 Net Monthly pays$5,5422.2My estimated monthly budgetMy family comprises of three family members expenses, which is me, my wife, and our one year old son. We live in an apartment in California. Estimated monthly Expense Amount ($) Rent 950 Childcare 0 Food 500 Taxes 311 Gas 200 Electricity bill 90 Internet services & Phone services 50 Grocery 400 My school tuition 2250 clothing 30 Transportation, Car maintenance & Insurance 300 Emergency Fund contribution 70 Masters degree savings account contribution 100 Entertainment, Gym membership 100 Roth IRA 100 Miscellaneous 80 Total expenses 5,531 Net income gain 11 Detailed above are my income statement and my estimated monthly budget. As much as my budget is small, I always aim to maintain it at the manageable level to avoid drowning in debts and even making some savings according to my short term and long term goals. My annual salary is $75,000 which translates to monthly gross pay of $6250. There are other charges levied such as federal withdrawing, social security, Medicare and California state levies bringing my net pay to $5,542. According to Randal (2007), housing is the most expensive item in California State. With an annual salary of $75,000 before tax, considering purchasing a home is a bad idea. As much as buying a house is one of my long term goals, I plan budgeting and planning for it after getting a well paying job or after establishing my business and making it successful to cater for purchasing a home. Therefore, with my net monthly salary of $5542, I opted for $950 rent for my apartment for my family. This is the average rental prices in my neighborhood since it is safe and it is not also expensive. California State is a region that is hard getting around without a car and therefore transportation forms part of monthly budget. My 2007 Toyota corolla car is reliable and uses fuel efficiently estimated at $164 per month, even with the soaring gas prices. My car uses 1 gallon per 29 miles and I drive to work and school daily at an estimated distance of 20 miles each way, translating to 40 miles daily, and five times per week. With additional driving on weekend when going out for entertainment or even vacation, the estimated monthly driving is calculated below: 40 miles dailyÃâ€" 30 days per month= 1200 miles 1200 miles per month/29 miles per gallon=42 gallons of gas per month Cost per gallon $3.961 Ãâ€" 42= $164 I have a good driving record, combined with my car’s liability insurance costs of $30 per month and car maintenance, my monthly transport cost is estimated to be $300 With a family of three, food is major item in my budget. With $500 I am able to feed my family well because here in California, we have several regional markets competeing with the common super markets. Averagely in the regional markets, the goods prices are about 40%-60% cheaper compared to the chain markets and they carry many items needed in the house like snacks, cleaning supplies, tools and tooth pastes among others. I installed â€Å"naked DSL† for only DSL and this provides me with full internet connection services at $40 per month. Furthermore, I went for pre paid phone services from T-mobile at $10 per month. This brings my monthly expense for internet connection and phone service per month to be $50. Californian weather is always good all year round and generally electricity is low, estimated to be $90 from my past average electricity bill of five months. My apartments pay for water and trash services. Similarly, I do not consume much gas and therefore a budget of $200 is enough per month. Moreover, I do my monthly cloth shopping at Old Navy and sometimes at Ross since they provide discounts and their cloths are of quality. As part of my short term goals to live healthy lifestyle, I have enrolled in a nearby gymnasium for my workouts three times per week. Moreover, as part of my entertainment I go out for few movies, go for some camping trips and eat out occasionally. Moreover, I make good use of free places like the beaches for my entertainment and therefore, an estimated budget of $100 is enough. Planning for my retirement and having protection in future is also part of my long term goals. Similarly, setting aside emergency funds in a savings account to help in resolving emergency situations swiftly was part of plan. My estimated monthly budget has catered for savings in form of Roth IRA is $150 and emergency finds contribution is $70. Moreover, I also save for my Master’s degree education that I plan to pursue after my undergraduate studies wit $100 per month. Lastly, Childcare is free in California State and is sponsored by the state government and therefore is nil in budgets. I also pay my tuition fees of $2,250 per month for my studies. Lastly, I do budget for $80 for miscellaneous expenses in addition to taxes of $311 2b. Managing LiquidityPlan to manage financesCash management according to AAT (2013) refers to concentration, collection and disbursement. My plan to manage my cash balances in a manner that satisfies my budget, maximizes cash availability and avoid risks of debts 2b.1Types of accountsIn management of finances, I will use ING Direct since they will be providing me with online pay services, savings services and checking services. Furthermore, the will allow me to create sub- accounts so that I can make savings for specific goals. 2b. 2Tools and process in maintenance of budget each monthBecause they offer many services and tool, I will use ING Direct as my primary tool for budgeting. I will be setting aside some money in specific pools of sub accounts, transfer the money back and forth automatically, and set up automatic payment of bills. These tools provided by the ING Direct bank will allow me to manage my finances effectively. The process in which ii will use in maintenance of my budget is a step by step process as outlined below: I will first of all get an account with the ING Direct because it has online checking and access to savings in addition to pay bill. The second step will be to set up an automatic bill payment for my bills per month. This means that for every regular bill per month that I have, I will set up an automatic payment of bill for that particular bill so that I do not have to worry about paying it when it is due. This will be done by creating the specifying the date and amount to pay it, and payment will be made automatically on that regular date I will also create a sub- account for each saving goal and irregular bill. This one will be for the other bills that usually come after several months has passed and sometimes crunch the budget such as my car insurance and gas bill. Similarly, I will set up sub accounts for specific saving goals such as my emergency funds, my Masters’ degree education and long vacation to France after my graduation. For these I will create sub accounts to set aside some money so that when their bills come however big or small they are, I am ready. These sub accounts I will give them names to identify them as my distinct funds such as â€Å"emergency funds,† â€Å"Masters Degree funds,† â€Å"car insurance,† â€Å"Gas bill,† and â€Å"France Vacation.†From there, I will set up an automatic money transfer into these sub accounts My next step will be to pay the bills as they come. This will be done after setting everything well and only remains with the responsibility of paying the bills as they come in. I will be paying my bills by 5th every month. I will ensure that I am on top of the incoming bills so that I do not get fined for late payments. Since I will have set most of bill payments to be handled through automatic transfer, I will not have many things to deal with; therefore few bills every month will get my attention. The fifth and the last step that I will do is that I will apply for debit card from Electric Orange checking services of ING that also functions as a master card to centralize completely all my spending. The debit card will be useful for regular purchases of household things like groceries. All these tolls and process will create a centralized view of my day-to-day expenditure and also form the core of my budget. 2b. 3Analysis of the current monthly budgetAnalysis of my current monthly budget was done under personal income expenses and budget. From the analysis, my monthly gross pay is $6,250 and net monthly pay is $5,542. Moreover, my estimated total monthly expenditure is about $5,531 with a net gain of $11. 2b. 4How and why my cash flows impacts the overall goalsMy short term goals include Building emergency funds, get a job after my bachelors degree, to study masters after my graduation, go for a two week vacation in France, build my personal development goals, and fitness goals. On the other hand, my long term goals include having my own business, buying a luxury car for my family, buy a house, pay college education for my children, and save money for my retirement. My cash flows impacts my short term and long term goals significantly and in different ways. My estimated monthly budget caters and also considers my short term and long term goals hence impacting them positively. For instance, my estimated monthly budget has set aside $70 per month for emergency funds, $100 per month for my Masters’ degree, $100 per month for my entertainment and gym membership to satisfy the lifestyle short term goals. Lastly, retirement funds also have a share in my estimated monthly budget at $100 under Roth IRA. The contribution towards achievement or realization of the goals is underway through financial support. This is evident from my estimated monthly budget. Probably after completion of master’s degree, the kitty can be changed to â€Å"children college fees† to start saving the future college fees for my children 2c. Credit ManagementDevelop a budgetAccording to Bullivant (2010), a person who is in financial debt need to first conduct a realistic assessment of the amount of money they take in and their expenditure amount. I use different ways in management and usage of credit. First of all, when I have a debt, I list all my fixed expenses. These are expenses that are the same each and every month such as the insurance premiums, car payments, my tuition fees and rent. Next, I do list the varying expenses like the clothing, entertainment and groceries. Listing down of all my expenses including te insignificant ones is very essential in tracking down my spending patterns, prioritize the rest and in identification of the necessary expenses. The main goal of my first step in credit management of listing of expenses is to ensure that the basics are fully settled such as my education, insurance, food and housing Contacting the creditorsWhen I have a problem of paying the debts as agreed, I immediately contact the creditor and explain to them why it is difficult for me paying the debt on time. I then try to adjust and modify my payment plans to levels that are manageable Secured creditsIf I have secured loans such as car loan and I am unable to pay it on time, I will sell the security (the car) and settle the debt rather than waiting for the creditor to reposes the car and sell it at an added cost. Similarly, if it is a mortgage, I will contact my lender to avoid foreclose 2c. 2Development of debt reduction processes after graduationCredit counseling I will go for credit counseling in any reputable organization or financial institution for advice on management of debts and money, assist in budget development, and for free educational workshops and materials. These counselors who are trained and certified in budgeting, debt and money management, and consumer credit will discuss with me my financial situation, and to help me in develop a personalized plan for solving my money problems 2c. 3Appropriate uses of credit and debit cardsCredit cardsOnline shopping-when shopping online credit card is the safest option because the insurers of the credit cards watch for fraudulent charges. It can be reversed quickly if its detected by the holder while debit cards are not protected in some instances like cash payments When making large electronic purchases- they are convenient is large electronic purchases in addition to offering warranty protection When on a vacation or travelling-it is suitable when away from home and it also adds anti-fraud protection. Moreover, by using credit cards during travels one can get perks such as cash back on purchases, frequent flyer miles, and discounts on the rental cars. Lastly, they are convenient for travel companies, airlines and hotels II.Debit cardsFor immediate payments since transactions are simultaneous and is the fastest When finances on the budget are automated-this is suitable for luxury and personal purchases and the card holder can use it as much as they want so long as they are within the budget. The card cannot work no more and this is advantageous since overdraft fees will not be incurred If recovering from poor habits of financial management or watching the finances. This is because credit cards are bad for some people in money management or living within their means. For best foreign currency exchange rate-it offers the current wholesale exchange rate especially when a person travels to a foreign country. 2c. 4Credit scoreA credit score according to Weston (2012) is a numeric representation of a person’s credit history and ranges between 300 and 850. The factors that impacts credit score include: Payment history- late credit card payments of skipping damages credit score while payment of credit card balances and bills on time and in full results to higher score Outstanding debt- it is good to use 25% and below of the available credit. Moreover, the more credit cards a person has that have been maxed out, the lower the credit score (Rich, 2013). The length of time for building credit- a person with a longer history of credit has a higher credit rating The credit report number of inquiries- more credit report inquiries will show up from the number of times a person applies for loans or credit cards. A higher credit report inquiry is an indication that the person is struggling with debt even if they never got a loan or used the cards (Rich, 2013). How I check my your scoreI usually check my score from AnnualCreditReport.com once per year for free. The website asks series of questions ranging from personal information, state, questions related to my finances I also use Fair Isaac Corporation (FICO) website at MyFico.com Lastly, I also sometimes purchase my credit report from the credit Bureaus directly in USA which are Experian, Equifax and TransUnion. Importance of having good credit scoreGood credit score makes it possible for banks to issue debit or credit cards, stores to accept checks and companies to manage their operations (Servigny & Renault, 2004). 2d. Tax ManagementThe applicable taxes to me as a married person with one child filling a joint tax forms are listed below Federal tax. 25% State tax. 7.5% Income tax 6% Social security tax. 6.2% Medicare tax. 1.45% Taxes in California State and United States vary and are categorized into different brackets. The tax brackets include age, single, head of household, married and pay tax separately or married and pay tax jointly. With my annual salary of $75,000, married with one child and paying tax jointly with my wife, I pay federal tax of 25% and income tax of 6%. However, the state tax, social security tax and Medicare tax are fixed in California state and cut across every citizen of all ages, whether married or not. The taxes from my income take a large percentage from budget annually and this also hampers my investments progress and my economic plans. My budget has incorporated some of my long-term and short term goals and I am forced to contribute minimal amounts because of the obligated taxes according to the law. 2d. 2Incorporating tax strategy into budget and financial goalsBuying and holding- a person is liable to pay tax on managed funds or shares held for one year or less at the regular rate of income tax. However, holding the assets for more than 12 months receives a discount on the capital gain of up to 50% Using tax efficient funds- making investment on funds like index funds which has low turnover ca reduce the liability of capital gains, and improves a person’s after tax returns Investing in retirement plans- a person can make contributions from their pre-tax salary so that the money is taxed at a very low concessional rate instead of marginal tax rate (Broomberg, 2013).

Plasmodium

Life Cycle of Plasmodium vivax (Malarial Parasite) Systematie Position Kingdom      :      Protista Phylum          :      Protozoa Class               :      Sporozoa Genus             :      Plasmodium Species          :      vivax Habit s and habitat:- Plasmodium is an intracellular sporozoan parasite causing malaria in man. The parasite lives in the RBC’s and liver cells of man and alimentary canal and salivary glands of female Anopheles mosquito. Structure:- Structure of plasmodium is different stages of its life cycle. A fully grown malarial parasite is amoeboid and uninucleated structure known as trophozoite.Trophozoite is surrounded by double layered plasma lemma. Cytoplasm contains Palade’s granules, endoplasmic reticulum, ribosome, mitochondria, vesicles and vacuoles having haemozoin. Cytoplasm contains nucleus having nucleolus and granular nucleoplasm. Life Cycle of  Plasmodium  vivax Hosts:- Plasmodiu m completes its lifecycle in two hosts (digenetic): Man and female Anopheles mosquito. 1. Primary or definitive host: Female Anopheles mosquito is the primary host of Plasmodium in which it completes its sexual life cycle. 2. Secondary or Intermediate host: Man is the secondary host of plasmodium in which it completes its asexual life cycle.The lifecycle of Plasmodium can be divided into three phases: 1. Asexual sehizogony 2. Sexual gamogony 3. Asexual sporogony ASEXUAL CYCLE OF Plasmodium, IN MAN Infective form of Plasmodium is known as sporozoites. Sporozoites are 11-12 µ long slender, uni-nucleated. Sickle-shaped structure present in the salivary glands of infected mosquito. When an infected female Anopheles mosquito bites a healthy man, a large number of sporozoites enter into the blood stream of man. Within half an hour, sporozoites enter the liver cells and undergo asexual multiplication called schizogony. 1. Asexual Schizogony:-Schizogony is the asexual phase of reproductio n of Plasmodium. It takes place in liver cells and RBC’s of man. Schizogony can be divided into following phases: a) Pre-erythrocytic schizogony b) Exo-erythrocytic schizogony c) Erythrocytic schizogony d) Post- erythrocytic schizogony a. Pre-erythrocytic schizogony: In the liver cells, sporozoites grow to form a large and spherical schizont. Schizont divides by multiple fission and forms a large number of cryptozoites. They may either pass into the blood circulation to start erythrocytic schizogony or enter fresh liver cells to start Exo-erythrocytic schizogony.Pre-erythrocytic schizogony takes 8 days to complete. b. Exo-erythrocytic schizogony: After re-entering fresh liver cell each cryptozoites divides to form a large number of metacryptozoites similar to pre-erythrocytic schizogony. Meta-cryptozoites are two types: Smaller micro-metacryptozoites and larger macro-metacryptozoites. The micro-metacryptozoites enter the RBC’s to start erythrocytic schizogony, while th e macro-metacryptozoites invade fresh liver cells to continue exo-erythrocytic schizogony. It takes normally 4 days to complete. c. Erythrocytic schizogony:-As stated above, the erythrocytic schizogony begins when the RBC’s of blood are attacked either by pre-erythrocytic cryptozoites or by exo-erythrocytic micro-metacryptozoites. It takes normally in 8 to 12 days after above 2 phases. Stages of erythrocytic schizogony are: i. Trophozoite Stage:- The merozoites (cryptozoites and micro- metacryptozoites) after entering into the blood stream, feed on erythrocytes, become rounded and modify into trophozoite. ii. Signet Ring Stage:- As the merozoites grow a vacuole appears in the center and the nucleus is pushed to one side.It gives a ring like appearance and known as signet ring stage. The parasite ingests haemoglobin and decomposes it into protein and haematin. Protein is use as food whereas unused haematin forms toxic. Yellowish brown malarial pigment, haemozoin. iii. Amoeboid Stage: – As the signet ring parasite grows, vacuole disappears and the parasite becomes amoeboid in appearance, thrusting out pseudopodial processes. This stage is called amoeboid stage. At this stage RBC develops numerous granules, the Schuffner’s granules. iv. Schizont Stage:- Parasite grows in size, becomes rounded and almost completely fills the RBC called Schizont. . Rosette Stage:- The nucleus of schizont divides by multiple fission to form 6 to 24 daughter nuclei. These nuclei arrange at the periphery, while the toxic haemozoin granules accumulate at the center of RBC. It appears as a flower rose, so called rosette stage. Nuclei of rosette stage are surrounded by a little cytoplasm and are develop into merozoites. With the rupture of the RBC, these merozoites are liberated into the blood plasma along with toxic haemozoin. These normally attack fresh RBC’s to repeat the erythrocytic cycle or may change into gametocytes.One complete erythrocytic cycle take s 48 hours in Plasmodium vivax. d. Post-erythrocytic schizogony:- Sometimes, some merozoites produced in erythrocytic schizogony reach the liver cells and undergo schizogony development in liver cells. This is called post-erythrocytic schizogony. SEXUAL CYCLE OF Plasmodium in MAN 2. Sexual Gamogony:- Formulation of gametocytes: After many generations in about 4-5 is the blood some merozoites increase in size to form two types of gametocytes; larger macro (9-10 µ), less numerous and contain large nucleus.Macro gametocytes are larger (10-12 µ), more numerous and contain smaller nucleus. SEXUAL CYCLE OF Plasmodium IN MOSQUITO When a female Anopheles sucks the blood of a malaria patient, the gametocytes reach the stomach of mosquito and formation of gametes take palace as follows: a. Gametogenesis (gemetogony) : Process of formulation of gametes (male and female gametes). i. Formulation of male gametes: The nucleus of microgametocyte divides to form 6-8 daughter nuclei. The cytoplas m gives out same number of flagella like projections and daughter nuclei enter in each projection.These projections separate from the cytoplasm and form 6-8 haploid microgamete or male gametes. This process of formation of microgamete is called exflagellation. ii. Formation of female gamete:- The mega gametocyte undergoes some reorganization to form a single haploid mega gamete or female gamete which is ready for fertilization. b. Fertilization: The male gamete enters the female gamete through the fertilization cone formed at female gamete and form diploid zygote or synkaryon. Fusion is anisogamous. c. Ookinete stage:The zygote remains inactive for sometimes and then elongates into a worm like Ookinete or vermicule, which is motile. The Ookinete penetrates the stomach wall and comes to lie below its outer epithelial layer. d. Oocyst stage: The Ookinete gets enclosed in a cyst. The encysted zygote is called Oocyst. The Oocyst absorbs nourishment and grows in size. 3. Asexual Sporogon y The nucleus of Oocyst divides repeatedly to form a large number of haploid daughter nuclei. At the same time, the cytoplasm develops vacuoles and gives numerous cytoplasmic masses.The daughter nuclei pass into each cytoplasmic mass and develop into slender sickle-shaped sporozoites are formed in each Oocyst. This phase of asexual multiplication is known as sporogony. Lastly, the Oocyet brusts and sporozoites are liberated into the haemolymph of the mosquito. They spread throughout the haemolymph and eventually reach the salivary glands and enter the duct of the hypopharyx. The mosquito is now becomes infective and sporozoites get inoculated or injected the human blood when the mosquito bites. The cycle is repeated. In mosquito whole sexual cycle is completed in 10-12 days.Incubation period: The period between infection and the appearance of first symptoms is called incubation period. It is about 10-14 days in Plasmodium vivax. Pre-patent period: The duration between the initial sp orozoites infection and the first appearance of parasites in the blood is called as pre-patent period. It takes about 8 days in Plasmodium vivax. Symptoms of malaria †¢ Mouth becomes dry, nausea and loss of appetite †¢ Headache, muscular pain and joint pain †¢ Chill, fever (106 ° F) and sweating all every 48 hours. †¢ Chill to sweating lasts for 8-10 hours. Liver and spleen become enlarged. †¢ Due to loss of RBC’s anaemia is caused. Control of malaria Malaria can be controlled by three ways 1. Destruction of vector 2. Prevention of infection(prophylaxis) 3. Treatment of patient 4. Public awareness 1. Destruction of vector (Anopheles mosquito) †¢ Mosquito can be killed by spraying DDT, BHC, Dieldrin, Malathion etc. †¢ Filling up ditches, gutters and pits where the mosquito breeds. †¢ Water surface can be poisoned by spreading kerosene oil, petroleum etc. †¢ A speedly flow of water prevents the mosquito larva and pupa flourishing. Biological control: Certain fishes (trouts, minnows, stickle back), ducks, dragon flies etc feed on larva and pupa of mosquito. 2. Prevention of infection (Prophylaxis) †¢ Use of mosquito nets. †¢ Screening doors, windows and ventilators. †¢ Using mosquito repellent creams (e. g. odomus), anti mosquito mat (e. g. Supermat) etc. 3. Treatment of patient: There are several drugs that kill different stages of parasite in patient. The oldest drug is Quinine; Paludrine kills almost all stages of parasite. Daraprism (single dose of 25 mg) is the most effective drug.Write short note on Plasmodium falciparum Plasmodium falciparum causes malignant tertian type of malaria. Fever reccurs every second or third day, that is, after 36 to 48 hours. Death rate is very high because the infected red blood corpuscles tend to clump into masses, thus blocking up small blood vessels of internal organs, such as brain, spleen, lungs, etc. It is also known as the tropical epidemic malaria of m an. Exo-erythrocytic schizogony is absent in P. falciparum. Read more:  http://www. hsebguides. com/2012/04/plasmodium-vivax-malarial-parasite. html#ixzz2G57xlaK6

Film and Media Studies - Research Paper Example In philosophical reconfiguration of cinema the researcher has discussed on the terms phenomenology, ontology, semiotics and ethical factors as found in the films. The utilitarian deontological ethics are the other philosophies discussed and they are supported by various references in the films. Cinema has been the major source of the knowledge of human psyche. â€Å"Every theorist, every film maker, every philosopher, every place has a different story to tell.† (Flicity Colman 2009: 5) Cinema started developing at the end of nineteenth century with the advancement in photography, mechanics, optics and chronophotography. Much have been discussed about the essence of cinema, what we call it a theory of cinema. Film theory is a scientific process of organizing through which we learn to be disciplined and as objective as possible in our judgement about films. (Pieter Fourie: 194) Fourie further discusses four subjects of film theory: According to some experts cinema is a movement, and some say it is an interval. Some thought cinema as an image and some thought it as writing. The experts also debate on the question whether cinema is a science or it is an art. The discussion further continued with the ontological, epistemological and anthropological connections of cinema. Cinema was considered as a new medium of communication in early twentieth century. Many Film theories were developed to study the essence of cinema. They include classic film theory, apparatus theory, auteur theory, feminist film theory, formalist film theory, genre studies, Marxist film theory, philosophy of language film theory, psychoanalytical film theory, screen theory, and structuralist film theory. The paper tries to discuss some of these theories through the examples of some films. The topic of discussion is based on particular category of cinema and that is psychological thriller films. The research paper on Media studies basically

U02d2 The Uninsured Problem - Essay Example It was noted that this number increased to 255.1 million in 2008, when compared to 253.4 million in 2007 (U.S. Census Bureau, 2010). c) The year has also shown the decline in use of private health insurances. It was noted that the health insurance from private providers has reduced from 202.0 million in 2007 to 201.0 million in 2008 (U.S. Census Bureau, 2010). d) The government health insurance saw a higher level of applicants and people have turned more towards the government insurance than the private. The year 2007 saw a total of 83.0 million while this increased to 87.4 million in 2008 (U.S. Census Bureau, 2010). e) As mentioned earlier the private insurances reduced a great extent. In 2007 the total percentage of people covered by the private insurances was around 67.5% which reduced to 66.7% in 2008 (U.S. Census Bureau, 2010). f) The employment based health insurances also saw a decline and it fell from 59.3% in 2007 to 58.5% in 2008. The number of people covered by health insurance for employment bases also decreased from 177.4 million in 2007 to 176.3 million in 2008 (U.S. Census Bureau, 2010). CNN has also presented a report which talks of the issue of uninsured. Here in an interview with Ron Pollack, the Executive Director of Families USA, stated, ‘The huge number of people without health coverage is worse than an epidemic’. He also went on to explain, ‘Inaction on health care reform in 2009 cannot be an option for the tens of millions of people who lack or lose health coverage each year ... the cost of doing nothing is too high’ (Pifer-Bixler, 2009). The report has also brought out more details of the issue of being uninsured. The report also states that, ‘Critics say the number of uninsured Americans cited in the Families USA report is misleading. "No one disagrees we have a problem with the uninsured," says Douglas Holtz-Eakin, who advised Sen. John McCain on domestic and economic policy during the 2008 election’

PA Design Report Assignment Example | Topics and Well Written Essays - 2000 words

PA Design Report - Assignment Example In an effort to increase the level of insulating sound in the arena, the material that was used for construction is reinforced concrete. It is among the few European arenas which is featured with a seating of 360 degrees. The arena is one of the busiest in the globe. It has millions of visitors streaming in every year to attend live music, comedy, tours, musicals and sporting events. A public address system is a system of electronics which comprises of a loudspeaker, an amplifier and a microphone and I geared towards amplifying the voice or sound of the speaker or recorded audio so as to permit effective communication with a large group of people. Public address systems play a very key role in the society. They are used in several places where their use is almost virtually indispensable. These include noisy places such as railway terminus, market places, churches, airports, harbors and the like. They are used to facilitate numerous functions which include campaigning in political ral lies; reaching to large multitudes; advertising and making sales in crowded places; making open air prayers among Muslim societies and the like. The Manchester Evening News Arena mostly uses or requires a public address system for functions such as announcing the performer in the next music or sport event; announcing the scores in a sports activity; transmitting the address of guests in attendance to the occupants of the arena; making announcements regarding procedures of departure or refreshment among several others. Concert The concert for which this design I slated is Rock band concert which shall be graced by the popular Aerosmith band. They shall be entertaining an expected huge crowd of people who shall come out to party given the reputation of the band. It is expected to be an all entertaining show piece which shall be in the form of a live music performance by the band. The Arena is very big and with the huge crowd that shall throng it, the Public address system that is nece ssary for the concert has got to be top notch. Major Design consideration The major factor of consideration in the design of a public address system is the space and pathway for the wiring lines and the public address system equipment. The design should create clear cut path ways where the cables shall pass so as to avoid human interference with the system. In the event that the cables are laid in the paths where there is constant traffic, there is a high chance that the traffic might stumble upon the wires and accidentally cut one, a number of or all of them. In this case, the public address system shall miserably fail (BARNETT, WOODGATE, JONES, & INGLIS 1991). What is worse is the fact that it might take a very long time to identify where the problem is before fixing it. This shall cause a delay in the schedule and a total mayhem in the arena. The best design of public address system for the arena is thus one which has all the cables buried in pipes underground and in concrete wal ls or pillars. The speakers and equipment should also be connected in parallel and not in series. Equipment connected in series have the tendency of all failing in the event where one of them fails. On the contrary, equipment connected in parallel keep working even after one of them or a number of them have failed. Sound on stage The stage is where a bulk of the activities shall be taking place as it shall be focus of attention. All eyes shall be on the stage and of course so shall be all

Conflicts ad Ethcs Coursework Example | Topics and Well Written Essays - 250 words

Conflicts ad Ethcs - Coursework Example A personal situation where conflict existed was between me and the fire brigade on the steps to take to put off the fire at my shop. In the end, it seemed the conflict only wasted time because we had diverse objectives. Mine was to try and save my property though it was impossible while the fire brigade’s was to try and put out the fire before it spread. The best conflict management style that we decided to adopt was collaboration. We decided to partner in order to achieve a common goal. Each of us was allowed to table their ideas, and in the end it leads to a win-win situation. Collaboration works in complex situations and trust is key. This method seemed to be the most appropriate for this situation. The ten basics for ethical communication are; seek to elicit the best in communication and interaction with other group members, speak non-judgmentally, listen when others speak, only speak from experience and perspectives expressing your thoughts, needs and feelings, speak to understand others, respect other’s boundaries, avoid speaking for others, manage personal boundaries, avoid interrupting and side conversations and finally everyone must have equal time to speak (Corvette, 2006). In accommodation, all the ethical guidelines were

Comparison of the key management and leadership aspects of Essay

Comparison of the key management and leadership aspects of organisations in the private sector, public sector and not for profit - Essay Example The behavioural approach to management is preferred to other approaches to management because it takes into consideration the behaviour of employees. Behaviour is one of the key factors that significantly influence performances of employees in various organizations. Therefore, managers who wish to lead and motivate employees should fully understand how behaviours of individuals under them respond to different phenomenon in the organisation. This will enable them integrate and influence the environment under which the employees work, without hurting their feelings. According to Sloan (1964), number of factors including manager’s biasness, the type of organisation as well as growth and development stage of an organisation among other factors influence choice of management approach in any given organisation. The development of the behavioral approach to management in an organisation The behavioral approach was derived from human relations approach management. This is because its major focus is human dimension at work. According to this approach, productivity is improved through proper understanding of individual’s behavior at work. Human relation theorists defined the employees as individuals, resources, and assets. In the behavioral approach, direct relation exists between employee satisfaction and production. Most human experts believe that workers are more productive when they are satisfied. Therefore, managers who wish to increase and improve organisation’s performance should work hard to meet the needs of people who are working for them. In addition, the theorists believe that employees can be empowered through training, motivation and providing appropriate tools for work. According to Tripathi (2008), the behavioural approach to management gives employees more flexibility in terms of autonomy, independence and empowerment in the organisational structure (Barnard, 1962). The behavioral approach points out that human rationality has constr aints when making the optimal decisions. These constraints are both practical and situational. Both employees and managers may make sub-optimal decisions due to influence by their behaviour. According to Vroom (1964), behaviorists insist that it is appropriate to humanize administration control process and encourage self-direction process rather imposing controls to restrict individuals. Managers should also consider various needs of individuals when influencing people because employees are different. In organizational conflict and change, behavioral approach remains to be practical. It addresses the inevitability of conflict and proposes that conflicting individuals should be understood. Furthermore, it acknowledges that individual often resist change on social aspects. Workers are often organised into teams in the behavioural approach. This is because managers in most organisations are biased to a flatter organisational structure. Application of behavioural approach to management began in 1930’s as a reflection of Hawthorne’s expression of human relation movement and organisational behaviour development. The field of organisational behavior was developed to fill the gap left by early human relation experts who concentrated on inter-personal relations and gave little attention to the patterns of group behavior. As compared to human relations approach management, behavioral approach concentrates it efforts in the study of human behavior. Douglas, McGregor, Chester Barnard, Rensis

The Respiratory Response To Exercise Physical Education Essay

The Respiratory Response To Exercise Physical Education Essay Exercise refines the ability of the cardiorespiratory system to take oxygen from air inspired into the lungs, and then load and transport it more effectively. Greater efficiency in the movement of blood through the cardiovascular system allows greater amounts of oxygen to be transferred from the respiratory system and also lung size does not increase due to exercise by any estimable degree.When you are exercising your respiratory system responds by increasing the respiratory rate and tidal volume as you start to breathe heavily, deeper and quicker, so that a greater supply of oxygen can get to the muscles. In contrast when you finish exercising your respiratory rate and tidal volume will decrease and gradually return to baseline. The increase in the respiratory rate and tidal volume in response to exercise leads to an increase in the pulmonary ventilation and thus greater delivery of oxygen to the alveoli to meet the increased demand of the exercising muscles. It also ensures greater removal of carbon dioxide which is produced by the increased workload of the musculature. Responses to Anaerobic Exercise In order to immediately meet the unexpected higher energy demand, stored ATP is the first energy source. This lasts for approximately 2 seconds. Muscles begin to fatigue when ATP resynthesis can no longer match requirement. If the exercise continues at a high intensity, and so Oxygen is not available at a fast enough rate to allow aerobic metabolism to take over, the production of lactic acid will reach the point where it interferes with muscular function. This is called the Lactate threshold. When stored ATP is broken down into ADP + P, the rising ADP level excites Creatine Kinase to begin the breakdown of Phosphocreatine (PC). The ATP-PC system can only last 8-10 seconds before PC stores are decreased. The lactic acid system (Anaerobic glycolysis) must then take over as the predominant source of energy production. High intensity (but sub-maximal) exercise can last for between 3 and 5 minutes using this system Responses to Aerobic Exercise Due to the necessity of Oxygen being present for aerobic metabolism, the first few minutes of low to moderate intensity exercise are powered by anaerobic metabolism as described above. The intensity and duration of exercise determines which fuel source is used. Fat metabolism is a slow process and so can only be used as fuel for exercise at less than 60% VO2 max. The intensity of exercise which can be maintained drops as fat cannot supply the required amount of energy. Continued low to moderate intensity exercise is then fuelled by carbohydrate and fat stores using aerobic metabolism. Carbohydrate is a much faster fuel source and so can be used for exercise up to 80% (in trained individuals). Carbohydrate stores within the muscle and liver can fuel exercise for up to 80 minutes. As carbohydrate stores get lower, the body has to rely more and more on fat stores. The effects of exercise training on the respiratory system : During exercise of the muscle cells, the organism use more oxygen and produce increased amounts of carbon dioxide. So after the exercise of the muscle cells your lungs and heart have to work harder to supply the extra oxygen and remove the carbon dioxide.Eventually your breathing rate increases and you breathe more deeply and also heart rate increases in order to transport the oxygenated blood to the muscles. Muscle cell respiration increases , more oxygen is used up and levels of carbon dioxide rise. The brain detects increasing levels of carbon dioxide and a signal is sent to the lungs to increase breathing. Breathing rate and the volume of air in each breath increase, which means that more gaseous exchange takes place. The brain also tells the heart to beat faster so that more blood is pumped to the lungs for gaseous exchange. More oxygenated blood is gets to the muscles and more carbon dioxide is removed. A conditioned athlete gradually develops increased maximum oxygen consumption (VO2 max) and lung capacity, which are contributors to being fit and healthy. Moreover, athlete who has not properly trained their cardiovascular system is likely to incur other injuries more easily by the rapid onset of fatigue and the consequent lowering of motivation and mental awareness. For anyone emulating at varying altitudes, they must allow themselves a considerable period to acclimatise before an event. Even climbing to a moderate altitude decreases the maximum uptake by 7% to 8% due to the change in atmospheric pressure. This decrease in oxygen being supplied to the muscles may decrease performance by 4% to 8% depending on the duration of emulation, a considerable disadvantage at the finish line. Finally, athlete who prepares and acclimatises well may still not match natives of high altitude areas such as the Andes, who have a larger chest capacity, more alveoli, larger capillary beds and higher red blood cell count.Thenceforth, people may suffer from altitude sickness when moving from low to high altitudes, sufficient time must also be allowed for these symptoms to vanish before starting intensive training. Conclusion : Biological control mechanisms increase ventilation in response to exercise to meet the demand for increased gas-exchange rates and to maintain PaCO2, pHa and PaO2 during moderate exercise and heavy exercise. Finally all humans possess specific kinds of muscle fibers, each of which is allotted relatively evenly throughout the muscles of the body in keeping with the genetic makeup of the individual. The two general muscle fiber types are fast twitch and slow twitch fibers. The definition between fast and slow is determined by the frequency with which the neuron that dominates the impulses that control the contraction of the particular fiber. Fast twitch neurons begin at a rate of approximately 10 times greater frequency than does a slow twitch neuron.Also the effective function of fast twitch fibers is necessary to anaerobic sports such as sprinting and jumping. Specialized exercise, such as plyometric programs, can increase the performance of fast twitch fiber. The proportion of slow twitch muscle fibers, the backbone to the muscle function in stamina sports such as marathon running and cycling, will increase in proportion to fast twitch fibers when the athlete undergoes vigorous stamina training.
