Bradford Protein Case Essay Example for Free

Bradford Protein Case EssayThe appearance of blue color showed the gift of protein in the BSA dilutions. The much diluted the solution was, the less blue it was. The R2 value of the measuring rod curve of BSA dilution was obtained to be 0.9972, which is close to 1. The closer to 1 the R2 value was, the more accurate the linear portion was.The mistake percentage of individually unknown was large 25.9% for skim milk, 95% for soy sauce, and 64.7% for egg white. The vast difference between the theoretical protein concentration and experimental protein concentration of the unknowns showed that Bradford Protein Assay must have limitations. The Coomassie dye only interacts with certain amino acids such as arginine, histidine, lysine, tyrosine, tryptophan and phenylalanine. However, each amino acid has different structure from each other thitherfore the Coomassie dye will interact differently with each amino acid. The Coomassie dye molecules are bound to proteins by elctronstati c attraction enhanced by hydrophobic bonding (Tal et al. 1984). Besides the interaction between Coomassie dye and amino acids, some compounds mountain arbitrate the result of the Bradford assay such as salt, fat, and detergent. Another factor that could influence on the Bradford assay is the protein sample must fall within the linear swear of standard curve.Another possible explanation for the difference between theoretical protein concentration and experimental protein concentration is human factor. The bottom part of the cuvettes was not vatic to be touched by because that was a region in which the beam of light goes through. The absorbance values at 595 nm are part of the variable of the standard formula that was used to calculate the experimental protein concentration of the unknowns. Therefore, the adjustments in these absorbance values would effectively affect on the experiment protein concentration values. Pipetting could be another error source because it was difficult t o pipette exactly 20 l Coomassie dye. Moreover, as recording the absorbance by using the spectrophotometer, different results were obtained within one sample. That means there were certain minor factors that influenced on the instrument.Bradford protein assay was used to determine protein concentration in several samples. Moreover, Bradford protein assay was not able to detect the presence of melamine in the food because the experimental protein concentration was obtained to be -0.005 mg/ml, which is invalid. Bradford protein assay didnt interact with melamine even though it contains so many amino groups (Field and Field 2010). Melamine is not protein because it doesnt have either carboxyl groups or functional groups, which are components of an amino acid. At high level, melamine can be toxic by combining with cyanuric acid to form insoluble crystals, which lead to the formation of kidney stones (Eufic, n.d.). Melamine amounts make the amount of protein look higher than they real are when tests that are used to detect nitrogen are used (Science Daily, 2009). Even though melamine has been notified to be toxic, there are still song of melamine-contaminated food in the market because the melamine tests are way to expensive to apply on every single product and take to much sequence to proceed.In future, to test the accuracy of the Bradford protein assay, more trials will be conducted with different proteins such as protein shake, chicken broth and 2% whole milk. Since the disability of sensing of the Bradford protein assay, some other methods should be conducted to see whether they could detect the presence of melamine in the food. The University of Minnesotas BioTechnology Institute developed an enzyme that is used in Bio Scientifics new MaxDiscoveryTM Melamine Test kit, which simplifies the detection of melamine contamination in food (World Health Organization, n.d.). The melamine deaminase enzyme is created to break one of the C-N bonds in melamine to rele ase ammonia.Clearly, the Bradford Protein Assay still has some limitations to detect melamine in the food. Therefore, to provide safety food, a better and inexpensive protein method inevitably to be created.Reference1. Anjarie F., Jeffrey F.

Similarities and differences Essay Example for Free

Similarities and differences EssayBut Ginsberg keeps accept alive by believe that salvation is possible through unity. Ginsberg does this by c everying Solomon his brother, his equal There can only be salvation if we embrace the world as one. wish he says in line 72 ah, Carl, while you argon not safe I am not safe, and now youre really in the chalk up animal soup of time. Like Whitman, Ginsberg believed in embracing the Other to achieve a sense of oneness that is not about being the same that about recognizing the inherent rights and individuality of each person. And just like Whitman, Ginsberg was as vocal, if not more so, about homosexualism in his poetry who let themselves be fucked in the ass by saintly motorcyclists, and screamed with joy, who blew and were blown by those human seraphim, the sailors, caresses of Atlantic and Caribbean love, who balled in the morning in the evenings in rose gardens and the grass of unexclusive parks and cemeteries scattering their sem en freely to whomever come who may. ( holler, line 36/38)And unlike in Whitmans poem, the reference to homoeroticism in Ginsbergs poem is more powerful because he used direct language as compared to Whitman especially when it is considered taboo and something short of a disease at that time. Indeed, including homoeroticism in Ginsberg poem can be seen as a tool to draw peoples attention to the reality that they refuse to accept in effect, Ginsberg is trying to make them see what they hope does not exist.More than just a homoerotic reference to Ginsbergs personal life, reading these passages as sociable commentary will help more in understanding the poems message and the statement it seeks to make at that time and context. Both writers yearned for a world that goes beyond the material. The only salvation possible from the degrading, repetitive and alienating modern world is the acceptance of the individual and the embracing of our inherent sameness and difference. art object Whitman portrayed a world that was full of promise by recognizing himself in each and everyone, Ginsberg depicted a world of counterculture to escape the stifling Molochs of modern society. He tried to find salvation in crossing the borders of language, time, society and experience. He crossed the limitations of the mind through the use of drugs and used repetition in his prepare to establish a quasi-religious tone or chant as an extension of the spiritual world. It is not surprising that there are many similarities amongst Leaves of Grass and Howl.Allen Ginsberg, after all, read Whitman and even took Whitmans tone and style in writing his own poem. Ginsbergs Howl is Whitmanesque in the sense that it took for its take the individual and its quest for his rights and freedom, and also he employed Whitmans natural speech rhythms and long lines. Whitman using free verse demonstrated his dedication to democracy, to a society not bound by rigid rules and uniformity but upheld individuality an d freedom, and Ginsbergs adopting the same showed his own perseverance to give voice to all those who want to break free from the constricting social norms his time presented.Their uninterrupted stream of consciousness writing style, without reflective interruptions that may diminish their spontaneity, rendered the truth as they saw it. To achieve this, Whitman and Ginsberg had to cross the borders of what was generally accepted as poetry. They challenged the barriers of what was considered poetry, and by doing so, made breakthrough poetry. ConclusionConsidered landmarks in American literature, both Leaves of Grass and Howl are remarkably unconventional, especially taking into account the time of their respective publications. Maybe the overall theme of salvation through unity was not new, but the means through which both poets achieved this definitely were during their time. Both Whitman and Ginsberg looked for new ways towards an uninhibited expression of the mind, as the above me ntioned salvation was only possible through challenging existing notions of order and social norms.Thus, by challenging the conventional rules of grammar and style in their poetry, the poets were, in effect, expressing their desire for a more liberal society, for hope for the people that through their works an emotion will be stirred within them calling out for the preservation of the human spirit and freedom of the individual. For cardinal poems separated by a hundred year interval and which continues to make waves even today, truly, it is a magnificent feat. Finally, the poems survival is enough credit to show that these are literary masterpieces worthy to be read as text by themselves and not as mere extensions of their poets.

Health Hand Hygiene

Health Hand HygieneThe complaisance of health care workers (HCWs) with go by hygienics and disinfection prime(prenominal) practices is considered one of HHUMC principle objectives because of its direct impact on healthcare provision . Hand washing is the single most effective measure of preventing healthcare associated infections.The transmittance Control committee runs an ongoing hand hygiene campaign to raise respectfulness rates. The main elements of which arePromotion of alcohol hand disinfectants which have been shown to signifi thunder mugtly improve compliance. Alcohol-based hand disinfection dispensers were installed in all hospital incisions Staff corresponding the infection control committee conducts routine and scheduled training on hand hygiene and the importance of alcohol disinfectant use for all hospital lag Hand washing Message the infection control team support the placement of hand hygiene posters in all hospital hallways and departments.The graphic remin ders are an effective measure in reaching a large make sense of the hospital population which includes staff and hospital visitors and promoting the messag about the importance of good hand hygiene practices and techniques. Observational Audit The Infection Control team carried an experimental audit of targeted staff that have direct patient contact in all hospital departments during the period January 2007 to November 2007. The IC/OHS committee provided an annual schedule for the departments to be visited and audited. The audit entails monitoring the practice of all Health-care workers (HCWs) against the requirement that hands must be decontaminated before and after every contact with patients or invasive devices, previous to any aseptic procedure and after handling body fluids or contaminated materials. These contacts are described as hand hygiene opportunities.Compliance can be defined as either washing hands with liquid soap and water or rubbing with an alcohol disinfectant, i n accordance with a hand hygiene opportunity.Compliance = Hand hygiene carried out x 100 Opportunity for hand hygiene (O)In quarter I of 2007 the compliance rate was 73%. During the quarter II, compliance decreased to 71% and in the quarter III and IV the compliance rate were 72.2 % 70 % respectively. The hospital-wide annual compliance average rate was 71.5 % which is an improvement from the 69% compliance rate of 2006 and a continued improment since compliance was measured in 2005. It is also above the hospital tendency for the first time.The annual score for each department is shown in the figure below. The HHUMC Infection Control Department set a QI score of 70% or more to be achieved in 2007 in locate to continuously improve compliance. The pie chart below represents the hospital department scores divided into the piece of hospital departments that have achieved the score.The departments that received the lowest scores are the departments that will be closely monitored and a lready received extra attention in order to improve their compliance with the hand washing policy.Most of the hospital departments reached their goal. Interventions such as staff training, promotion of alcohol hand disinfectants, putting posters and monitoring staff performance played a significant step in improving hand washing compliance in the hospital.During the observations, barriers to hand hygiene were identified, e.g. no makeup towels, alcohol disinfectants in dispensers. Some of the observations also gave concern about staff not decontaminating their hands following removal of gloves. Findings were identified and transmitted to the nursing director, department managers, and staff on duty after the audits.Future plans for hand hygiene campaignThe infection control department plans to continue its activities to further promote and train the the hospital staff in the use of alcohol hand disinfectants.The observational audits will be repeated at least twice each year. surplus engagement with the nursing departments that have scored the lowest in the recent audit has already begun and the root causes for the lack of compliance with the hand hygiene recommendations will be analysed. The causes that are associated with lower compliance are related to the infrastructure and ease of available sites for hand disinfection as well as the promotion of the hand hygiene culture.

Importance Of Distribution Channels Marketing Essay

Importance Of Distri furtherion Channels Marketing EssayMeaning in the field of honor of commercialise, transfers of statistical dissemination indicates routes or pathways by which goods and services flow, or more from producers to consumers.We can define form altogethery the dispersal agate line as the set of mutually beneficial marketing institutions participating in the marketing activities involved in the movement the flow of goods or services from the primary producers to ultimate consumers.A channel of scattering is a path traced in the transport or indirect transfer of ownership of a product as it moves from producers to consumers.A channel is pipeline done which a flows on its way to the consumers. The manager put his products into the pipeline marketing bring and it moves towards various marketing people and reaches the ultimate consumer which is the other end of the channels.Components of scattering system The distribution system involves two components such as below.Channels of distributionPhysical distributionChannels of distribution means a surgery through and through which the products ar transferred from the producers to the ultimate consumers. It also known as marketing channels. The channels members such as merchants agents wholesalers and retailers are middlemen in distribution and they perform all marketing hunts. These channels members such as merchants agents wholesalers and retailers are middlemen in contribution and try perform fit to marketing functions. These middlemen facilitate the process of exchange and draw time, place and possession utilities through matching and sorting process. Sorting enables meeting or matching the supply with consumers demand.Physical distribution it looks after physical discourse of goods and assures maximum customers services. It aims at liberty chiting of deli real of right goods at the night distribution activities coverOrder processingPackagingWarehousingTransportation inscription controlCustomer service.All middle in distribution on performs these function and they assure putting the products with in an arms length customers desire and demand.Elements of distribution channelsPath way distribution channels are a pathway through which products and services flow from producers to customers.Flow this of goods and services in ensuant and usually in directional.Composition it is composed of intermediaries also called middlemen who participate in the flow of voluntarily.Objectives although channels components largely strive to achieve mutually acceptable objectives, the manufacturer focus is an achieving corporate marketing objective.Leader manufacturer leads the channels components and their behavior is regulated by mutually acceptable code of conduct, trade customer and or contracted stipulation. Thus the guild acts as the channels caption and manages the pathway.Functions the intermediaries perform such functions which facilitates transfers of ownership and possession of goods and services from traffickers to consumers.The function performed by intermediaries is been classified as followsSorting out it involves breaking a homogeneous through grading or inspection.Accumulation it involves bringing a number of like products together into a large homogeneous supply. This process is called concentration.Allocation it involves sorting out of accumulated products and consists of breaking down a homogeneous supply into smacker lots it is also referred to as the process of dispersion.Assorting it involves building an assortment of different but perhaps a related product to form a stock of an intermediary. At the manufacturer aim assortment are dictated by production engine room while at the consumer and, use assortments are governed by consumption pattern. These discrepancies in assortment take a crap opportunities for intermediaries to participate in the channels of distribution.Importance of distribution channelsChannels of distribution for a product the route taken by the title to goods they are from the producers to the ultimate consumers. It is very important because product in one place while the consumption scattered in many place. So t here(predicate) is great(p) gap surrounded by producers and the consumers. So through channels of distribution can only fill the gap. A channel of distribution connects a link between the producers and the consumers.The middle man plays an important role in consumer orientation demand. The middlemen are specialist in concentration equalization and dispersion, i.e.collects output of various producerssubdivide the products according to the needs of the consumers.disperse this assortment to the consumers.The success of channels of distribution COD is completely depending upon the middlemen as they give rise time and possession utility. The COD helps in making products operational at right time in the night place and in the right quality.Marketing is a comprehensive term, which includes distribution also, distribution is a function to distribution or sub divided the producers goods to various specific markets which incurred to all ultimate consumers.Role of channels of distributionChannel of Distribution plays a very important role in achieving the marketing objectives of a company. Undoubtedly, the manufacturer of product or services creates involve utility but the distribution channels create time and place utilities. According to Drucker, both the market and distribution channels are offer more crucial than the product. They are primary the product is secondary.In an ever widening market, pointly in consumer goods market distribution channels have a distinctive role in the successful implementation of marketing plans and strategies. These channels performing the following marketing functions the machinery of distribution.The searching out of buyers and seller.Matching goods to requirements of the market(merchandising)Offering products in the form of a ssortments packages of items usable and acceptable by the consumers /users.Persuading and influencing the prospective buyers to privilege a certain products and its maker personal selling /sales promotion.Implementing pricing strategies in such a manner that would be acceptable to the buyers and ensure effective distribution functions.Participating actively in the creation and establishment of market for a new product.Offering pre- and after sales service to customerTransferring of new technology to the users along with the supply of products and playing green resolution in our country.Providing feels back information, marketing intelligence and sales forecasting services for their regions their suppliers.Offering credit to retailers and consumers.Risk- equipage with references to stock h antiquateding transport.MIDDLEMAN IN DISTRIBUTION CHANNELSMerchant intermediaries are those channels member who take both title to and position of goods from the transaction member (s) and chan nels them to the subsequence. These whitethorn classify as followsWholesalers A merchants wholesalers may be defined as that intermediary who buys goods in bulk from manufactures and sells them largely to incidental intermediaries participating in the channel, namely, semi-wholesalers and retailers, they buy the goods and sees the same on their own account and risk. They take title of goods and they resale the goods at a profit with commission.Retailers A retailer may be defined as that merchant intermediary who buys product from preceding challes members in smaller assorted lots to suit individuals consumer requirements. Retail in the final examination middlemen in the channel of distribution as he is going to sell products to houses holds consumers for non- business use.Retailers are further classified as institutional and non- institutional retailers.The institutional retailers areConsumer Co- operative stores.Fair price shops.Departmental stores.Chain / multiple stores.Mail order houses.The non-institutional buyers areStress sellers.Peddlers.Hawkers.Agent IntermediariesAgent Intermediaries are those channel components who never take title to end usually do not take title to and usually do not take possession of goods but merely assist manufacturers, merchants intermediaries and consumers in carrying out transactions of sale and purchase. There for, unlike merchant intermediaries, they do not buy or sell goods on their own account but merely bring buyers and sellers together in order to strike a transaction. There exist an agency relationship between such an intermediary manufacturers where in the former acts as agent and the latter as his principal, such agent intermediaries solicit orders, sometimes with discretion a meliorate prices, and determines the term of sale with buyers.Agent intermediaries are usually compensable for their services by way of commission on the value of sale affected through them or any other basis naturally agrees upon.Agent intermediaries may be further classified as followsSole selling agent.Selling agent. bearing agent.Brokers.Channel endThe first problem of channel design in whether you want direct sale to consumer or indirect sale i.e., sale through middleman under the direct sales the channel problem becomes problems of company organization. If the company chooses the indirect route, it must consider such problem as the grapheme and number of middlemans and methods to be employed in motivating and controlling them. The selection of these middlemen beings with the knowledge of ultimate customers-his needs and desires for distribution services. Customer conveniences and economics of unshared distribution will determine the number of middleman employed. The company must choose whether to attempt extensive, selective or exclusive distribution or crew of all three emblems, the decision is made after the careful analysis of product, customer, dealers, and company objectives and policies, and the co nflict with in the channels and any other relevant ciphers. The company must resolve channels and bring the product profitably to the market.In the chance managements a manufacturer has to make three decisionsSection of a particular middleman at each level and in each market.Number of middlemen at each level and in each market.Selection of particular middlemen for selling goods, with or without any exclusive rights of distribution.Once the company has determined, its basic channel design and levels of distribution, it has to select middlemen appoint them, motivate their efforts, evaluate their utility periodically and if necessary, it has to reorganizing the channels in the light of experience.Channel choiceChannel decisions also require special attention as involve long term commitments to other firms with whom marketer enters in to a contract. The problem of selecting the most suitable channel 0f distribution for a product is complex. The most fundamental factor for channel choic e and channel management it economic criteria, viz., cost and profit criteria, we have to consider a number of factors such as the nature of the product, market trends, competition outlooks pricing policies normal consumer needs, as well as needs of the manufacture critical factor.Product factorsProduct manufactured by a company itself is a governing factor of great force in the distribution channel selection. The product attributes status the channel decision in the following manners,If a commodity is perishable or fragile a producer prefers few and controlled levels of distribution.For durable and standardized goods longer and diversified channel may be necessary.For custom made product direct distribution to consumer or industrial user may be desirable.Systems approaches needs package deal and shorter-channel serves the purpose.For technical product requiring specialized and selling and serving talent, we here the shortest channel.Products of high unit value are sold directly b y traveling sales force and not through middlemen.Market factorsUnder the youthful concept of marketing market factor shape all marketing decision. As a corollary, the distribution channel choice is considerably influenced by market factor.Consumers the numbers of consumers, their geographic location and purchase pattern considerably govern the choice of a channel.Intermediaries the relative strength and weakness of intermediaries and the difference in the type of function performed and facilities and privileges desired by them often determine the choice of channel.Competitors the distribution channels used by competitors also influence the channel choice because it may be the customary channel used by all those operating in the field.If the market size is large, we have many channels where as in a small market direct selling may be profitable.Company factorsLike markets and products, companies own strength and weakness significantly influence and shape channel choices.Financial st rength a company with substantial and financial resources need not really too much on the middlemen and can offered. To repress the levels of distribution a weaker company has to open on middlemen to secure financial and warehousing relief.Past channel experience in case often old and established company its past experience of working with certain kind of intermediaries also condition channel choice.Marketing policies the marketing policies relevant to channels decision may relate to advertising delivery, after sales service and pricing.Reputation it is said that the reputation travels faster than the man. It is true in case of companies also who appetite to select distribution channels.MiddlemenMiddlemen who can provide wanted marketing services will be given first preference.The selected middle men must offer maximum co operation particularly in promotional services. They must expect marketing policies and programs of the manufacturers and actively help them in their imple mentation.The channel generating the largest sales script unit cost will be given top priority this will be minimizing distribution cost.CompetitorsMarketers closely watch the channels used by rivals. Many a times, similar channels may be desirable to bring about distribution of your products also. Followers, sometimes marketers deliberately avoid customary channels (dominated by rivals) and adopt different channels strategy for instance, you may by pass retail store channel (usually used by rival) and adopt doorsill to door sales (where there is no competitors).Environmental factorsMarketing environment can also influence the channel decision. During recession or depression, shorter and cheaper channel is evermore preferable. In times of prosperity we have a wider choice of channel alternatives. Technological inventions also have impact on distribution. The distribution of the perishable goods until now in distant markets becomes a reality due to cold storage facilities in tra nsport and warehousing. Hence this led to expanded role of intermediaries in the distribution of perishable goods.Arranging in classes of distribution channels and intermediariesTypes of distribution channels broadly distribution channels may be classified as a non integrated and integrated channel is individual or conventional marketing channels.

Demand and Supply in Microeconomics

Demand and furnish in MicroeconomicsIntroductionEconomics is a study of how to use limited imagery to satisfy unlimited pile wants. Demand and provide is the two main concept of the modern economic. Demand is what people want and supplement is how umteen goods easy for people want. In free market place the value of good is determined by the numbers of consumers and how many products available for them. As the result of that, when consumers understand the fullfulness of entreat and supply they will have ability to decide when they can buy a product with pocket-size price and the suppliers can set the right price of this product and decide how many product they will make. In this case study we will evaluate the theory of necessary and supply. We in like manner apportion an example of requirement and supply in food market in Hanoi in storm season.TheoryDemand and supply might be one of the basic concepts of economics. It is the core of market thriftiness. Demand is the price or criterion of a product or service desired by consumers. The prerequisite relationship refers to the relationship between the price and quantity conducted, which are the price and quantity people willing to pay for. Supply is the amount of products a market produces. The supply relationship represents the relation between the price and quantity supplied, which are the price and quantity suppliers willing to produce. Therefore, price is the main concern for entreat and supply to consider increased or deducted, and so posit and supply vary according to the price. According to the law of demand and supply, the higher of a products price the more(prenominal) suppliers will produce and the less people will buy. Because of that, the market price is metamorphoses. ( Investopedia news and articles, copyright 2010 )In such a case, the quantity supplied is greater than the quantity demanded and there is a surplus of the good on the market. From the graph we see that if the unit price is $3 (assuming relative pricing in dollars), the quantities supplied and demanded would be sum Supplied = 42 unitsQuantity Demanded = 26 unitsTherefore there would be a surplus of 42 26 = 16 units. The sellers past would lower their price in order to sell the surplus.Suppose the sellers lowered their prices below the equilibrium point. In this case, the quantity demanded would increase beyond what was supplied, and there would be a shortage. If the price is held at $2, the quantity supplied then would beQuantity Supplied = 28 unitsQuantity Demanded = 38 unitsTherefore, there would be a shortage of 38 28 = 10 units. The sellers then would increase their prices to make more profit.The equilibrium point must be the point at which quantity supplied and quantity demanded are in sleep, which is where the supply and demand curves cross. From the graph above, one sees that this is at a price of approximately $2.40 and a quantity of 34 units. (NetMBA.com)In general, if the price of a product is at low level, more people want to buy it and the demand will increase. As the result, there will be a shortage. The supplier instantaneously will be willing to produce more because people still want to use that product. So the supply increases. It will keep increasing to a point where customers demand and the quantity of that product is equal. Thus, there is a tendency toward an equilibrium point where quantity demanded equals quantity supplied. On the other hand, if the price of a product is at high level, less and less people want to buy it and so the demand decreases. In the end, there will be a surplus. The supplier now will drop down the price in order to attract more customers. This price keeps going down until they sell all break through of the surplus. So, the price is moving backward to an equilibrium point where price demanded equals price supplied.So, how a firm know when to produce more or less? As in THE TIMES 100 article states that An important aspec t of marketing is knowing what the demand is for your products. All companies engage in marketing activities to find come out of the closet what the demand for their different products will be. For example, Coca-Cola will want to investigate market trends in the carbonated drinks sector, while a bank will want to find out about the demand for financial services. Armed with this information they are able to make appropriate pricing decisions based on what other suppliers are doing, as well as on the demand from consumers in the market.Some main factors causing the change in demandEconomic factors When a country parsimoniousness is good and people have more money in their pockets. They likely want to consume more and thus the demand will increase kind factors As the social trend changes, people might have less time for taking care of their houses. Therefore, they will need to buy more airstream machines and hire employees to do all the cleaning and cooking services. So, there will be more opportunity for firms making washing machine and higher demand for cleaning service.The quantity and the price of competitive goods the higher the price of a competitive good, the higher will be the demand for this good as customers change from competitive goods. An example for this is that, if the price of i-phone mobile phone goes up, the demand of other smart phones will increase.Some main factors causing the change in supplyWants it is simply the demand for a busy product. As the demand rises, the supplies will rise also.The number of suppliers If new companies join the market, usually the supply increasesNatural and unorthodox events If earthquakes, floods and fire occur, the output likely to drop. Wars, which affect the supply of imported raw materials, the breakdown of machinery, may happen anytime.(John Sloman (1998), and The Times 100, Copyright the Times Newspapers)Demand and Supply in Macroeconomics and MicroeconomicsMacroeconomics is the study of the whole eco nomic activities which include inflation, recession and unemployment Therefore, it concerns with the thoroughgoing demand and total supply.If the total demand is high compared to the total supply, inflation and balance of trade deficits will occurInflation is the increase of the price level in the whole economy. If there is a rise in demand, suppliers likely play off by setting up high prices. After all, if the demand is still high, they can sell as good as before and make a lot of profits. Inflation will happen when all suppliers just keep their prices at high level.The balance of trade deficits happens when import is greater than export. When the aggregate demand rises, people will have a tendency to buy more foreign goods, more imported cars, wines, electronic equipments will be consumed. If the inflation is also high, the domestic goods are even harder to compare with foreign goods. As the result, our goods cannot be consumed not only by our country but also foreign countries. If the total demand is low compared to the total supply, unemployment and recession will occurRecession is the economic situation when business activities are declined. As the result, fewer and fewer people are willing to spend money. Thus, firms will have a lot of surplus goods. They likely to buy less from the manufacturers, which will decrease the production in return.Unemployment will happen if manufacturers do not need to produce anymore.Microeconomics is the study about the individual parts of economy, individual firms. It studies about the demand and supply of limited products and services such as cars, clothes, food, electricians.We cannot make as many goods as want because the lack of resources. There are some choices must be make in our societyWhat should be produced? We dont have enough resources to produce as many goods as we want. Therefore, we have to decide how many cars, how many buildings, how many hospitals should be produced?How should things be produced? If ther e is more than one way to produce thing, we have to decide which is the best.Who will use our products? This is the problem of income. We have to decide what the wage of particular job such as doctor, engineer, farmer Because if they have more money, they likely to consume more (John Sloman, 1998)Case studyIn October of 2008, Ha Noi was flooded by heavy rains. Because the drains did not work effectively as it was supposed to be. People in Ha Noi had a terrible experience because of the scarcity of the food.Learning from that experience, people in Ha Noi today usually store food when a storm is announced coming. As the matter of fact, in the evening of July 17th in 2010, the news forecasted that a storm might be coming. However, in the next day, the weather turned normally again. Because of the worry about the scarcity of food, people in Ha Noi already rushed to the super market and bought as many foods as they can. The change of demand and supply made a lot of supermarket out of sto ck, also the price of the food was doubled the supposed price. At some supermarket, people had to struggle, pushed each other just to fill up their fridge. As a result, they had to eat frozen food for months while low price fresh food is selling everywhere. At this point, the market had to suffer the decrease of food demand because people already had food in their fridge.In this case, when a demand surprisingly increase the quantity supply cannot afford to satisfy all the require instead of that is the increasing of the price. When the demand drops down, the quantity supply stays the same but the price has to fall to attract more customers.ConclusionNowadays, the real introduction economy is too complex that even in some cases the law of demand and supply cannot be applied. The market today is changing ceaselessly many individual speculations are getting even more and more uncertainly. Therefore, people shouldnt rush in deciding to buy anything. In my opinion, stock and real land ed estate markets are really risky for those who only follow the market tendency meaning to say the majority of people and dont have enough knowledge of how the economy works. Furthermore, the government should be flexible with the policy to keep the market price at a suitable level so that both customers and suppliers can oblige with, and also avoid inflation and unemployment.

Supervisors and Managers Responsibilities Essay -- Organizational Stru

Many organizations and establishments have philosophies in how an organization is to be operate and which positions are necessary to execute the plan. One of the crucial positions that make the establishment function is that of a Supervisor. The term supervisor is a word with Latin grow which means to look over, however, a supervisor is viewed as a person who is an immediate overseer to an employee at a workplace. The supervisor is the person an employee would directly discover to for any work related situation. A supervisor plays an essential part of the management team that gives an organization purpose and leadership by being trusty for employees progress and productivity (Bittel & Newstrom, 1992). Supervisors and Managers share some similarities in that they oversee people however they have clear differences that can distinguish one from the other.

War of 1812 Essay -- essays research papers

The War of 1812 The United States of America began to see the effects of Anglo-French War by the primaeval 1800s. This European quarrel began affecting the United States shipping industry. Britain and France were violating neutral shipping rights of Ameri merchant ship merchants. They thought of America as weak due to inadequate while the nation had to develop. These violations were the first and primary provoking factors that led to war with Britain. There was reason that Britain became the target of US military rather that France. Britain has influenced Indians around Lake Michigan to defy white settlement. This was one of the primary reasons the English were chosen as our foe. Britain had the Indians do this as an attempt to keep the U.S. border as low as realizable - not exceeding the Canadian border. France had made no such attempts to interfere with America they in fact only had the simple desire to obtain our goods. They did with hopes of gaining this territorial dominio n for their new colony later. Consequently, Britain became the target, and it led to a continuation of the American Revolution. The primary cause of the war with Britain was the fact the neutral shipping rights were violated by Britain, and though France had alike violated these rights, there were other issues that the British were responsible for. Britain blockaded the United States in such a manner it was no longer accomplishable to export goods by ship. The British were not doing this to harm Americas economy, however it was extremely harmful to the economy of this young country. Britain was doing this so that France could not import as numerous goods that would behoove them in the war. France desperately needed various goods that could be imported from the United States and they were willing to pay where Americas economy could have benefited tremendously. Though the fact of the point is Britains enormous, notorious navy would not allow the exporting of Americas goods. The de sire for Canadian colonies to join the United States, and the accusations of the British supplying Indians with weapons to be used against the U.S. are also causes of theWar of 1812.The battles of this war were primarily fought on US soil. The British military was surprised by the United States military. They had underestimated of the young country that was blossoming and flourishing on freedom. The battl... ...e was gained by either of the opposing forces of the war. The British suffer tremendous casualties. The U.S. gained nothing in terms of land. This war was indeed pointless it is amazing how one leaders feelings can kill thousands. President Madison got involved in this war because he felt that the countrys pride had been stepped on. The opportunity to challenge Britain cameup, and Madison jumped into it readily.The War of 1812 was definitely a war this nation could have gone without taking part in. It was ridiculous to lose so many valuable American lives for such worthless reasons - pride. self-exaltation should be swallowed in certain occasions this was definitely a time in which our leaders of America could easily have swallowed their pride at much(prenominal) less of a cost. American merchants and greed can be held at fault for this costly American war. Had merchants not pushed so hard this war whitethorn had been avoided, but they fact is it did. The War of 1812 did, however, strengthen Americas ability to be self-reliant. This is valuable, but not worth the thousands of lives that were spent obtaining this minor wartime convenience.(american History - a survey by alan brinkley) and encarta 95 cd
