Antibiotic Investigation

Antibiotic Investigation

Staphylococcus epidermidis

The most effective antibiotic on this type of bacteria is penicillin. This was discovered after carrying out an experiment on this bacterium. Penicillin was used among other antibiotics, which are used to cure bacteria-related diseases. They are tetracycline, streptomycin and bacitracin. Staphylococcus epidermidis was sampled and the three antibiotics were applied on the bacterium. They showed different sizes of inhibition zones. The biggest diameter of inhibition zone was shown by penicillin. This means that it is the best in resisting this type of bacteria. Streptomycin had the smallest diameter of inhibition zone. Therefore, it is the least effective antibiotic on this bacterium (Florey, 38).

Escherichia coli

The most effective antibiotic for this type of bacteria is streptomycin. An experiment was carried out and streptomycin gave the best results in resisting this bacterium. A Petri dish was used to place antibiotics. The antibiotics used were bacitracin, penicillin, streptomycin and tetracycline. After twenty-four hours, Escherichia coli were introduced. The antibiotics were supposed to form zones of inhibition according to their efficiency. Streptomycin formed the largest diameter. It was concluded it is the most effective. The antibiotic with the smallest diameter was penicillin. This means it is the least effective in treating this type of bacteria (Birch & Fleming, 42).

Penicillin

This antibiotic originated from penicillium fungi. It is a group, which include other types of penicillin. For example, other types include penicillin G, procaine penicillin and benzathine penicillin among others. This antibiotic was among the first to be established in curing diseases like syphilis. This drug is also efficient in treating infections from bacteria like staphylococci and streptococci. Penicillin is used by many doctors to treat infection caused by gram-positive organisms. All types of penicillin are beta-lactam antibiotics (Birch, Fleming, 79).

It was also the first antibiotic to treat tuberculosis. This drug treats diseases caused by bacteria infections. It is administered by injection and no formula that can be administered orally. This drug is good at curing infections caused by Escherichia coli, endocarditis, plague and useful to veterinaries too. It is effective on large animals with gram-negative bacterial infections. Streptomycin can be used as a pesticide. It subdues the growth of bacteria, algae and fungi. It can stop fungi diseases in vegetables, fruit crops and other plants (Flowery, 81).

Bacitracin

Bacitracin is produced from Bacillus subtilis. It cures babies with pneumonia and it is completely absorbed in the blood. However, adults cannot use it because it has potential to cause kidney damage. Another use of this antibiotic is used as an ingredient of some medicines to cure eyes and skin diseases. Bacitracin is commonly used to apply areas of skin after tattooing. It prevents any sorts of allergy when healing.

Tetracycline

Tetracycline is classified in the group of broad-spectrum drugs. Bacteria has obtained resistance towards this antibiotic so it uses had decreased. Tetracycline is use for treating bacterial infections in the urinary tract, Chlamydia and intestines. This antibiotic is used on patients who are allergic to antibiotic, which are beta-lactams. Currently, tetracycline is mainly use to treat acne especially when it becomes severe. It is also utilized by veterinaries to treat animals like pigs. Other diseases it may be used to cure are cholera, plague, rickettsia, brucellosis, anthrax and tularemia among others. Tests are being carried out to confirm whether tetracycline can treat some disorders, which are inflammatory.

Decision Making Approaches

Decision Making Approaches

Rationality Using Decision Tree Example

Decision trees are one of the rational decision-making approaches used across many fields including marketing. They represent the decision, its points where to be made, and the probable results. It aims at establishing all the possible solutions and events as well as their potential impact in order to come up with the best decision offering the optimum utility. The following is an example of a decision tree on which investment to take (decision-making-confidence.com 2012).

My company is considering whether to invest in two of the investment tenders on the supply of commodities for a certain company. The two tenders are NM1 and NM2. The company has three options, to invest in NM1 or invests in NM2, or both. The tender prices are most likely to be as follows

NM1 cost for tendering == $20,000, and a supply cost of $11,000 if tender is won

NM2 costs for tendering == $17,000, and a supply cost of $6,000 if tender is won.

Cost of tendering both is $32,000, and supply cost of $ 14,000 after tender is won.

The possible prices for the tender are as follows in the table, together with their probability

Options Possible price $ Probability of winning tender
NM1 150,000 0.30
120,000 0.75
NM2 120,000 0.45
105,000 0.87
Both NM1 and NM2 200,000 0.43
180,000 0.75

 

The decision tree will look as follows

 

0.30

 

2           150,000

 

120,000                               0.75

 

 

 

0.45

 

1                                      3           120,000

 

 

105,000                             0.87

 

 

 

0.15

4           200,000

4

 

180,000

0.75

 

 

 

From this decision tree, the best option to make is tendering for both tenders at a price of $180,000, since it has the highest benefits of $100,500. This is calculated by subtracting the costs of tendering and supply costs estimated if the tender is won, and finally multiplying by the probability to get what would be the best option to go by. Therefore, number 21 scored the highest, meaning that my company should go with that option (Ipson Marketing 2009).

 

Rationality using Payoff Matrix

The payoff matrix is an analysis tool summarizing advantages and disadvantages of a decision in a tabular form; it lists all the payoffs, both negative and positive under all the possible combinations that can generate the intended goal. The matrix is used for comparing the best benefit for two competitors who are competing for the same resources. When one wins, the other one loses. An example of a payoff matrix is as follows (Russell 270).

My company PLC is in a competition with company XYZ, competing for the same market, where there is a 100,000 units to be sold to a client. My company and XYZ are to compete for this amount of money by bidding. One can either bid at $0, $1, $2. If we bid at the same price, we split the amount into two. If each bids with different price, one will lose to the other. This can be represented in a payoff matrix as follows

 

Payoff Matrix

 

Column Player Company XYZ
Row player

PLC

$0 $1 $2
$0 50,000/50,000 0/99,000 0/98,000
$1 99,000/0 49,000/49,000 -1,000/98,000
$2 99,000/0 98,00/-1,000 48,000/48,000

 

From the payoff matrix, it is clear that if we bid at $2 while XYZ bids at the same, we shall both have equal share of selling to the client. At $2, there would be more benefits for both companies since each will earn $96,000 each, while at $1, one company will earn nothing while the other will take $99,000. Therefore, the company should aim to bid at $2 where it will supply less at a higher price.

Business plan

Business plan

Having a business plan is important when starting a business. An entrepreneur needs to formulate objectives for the managers of the business. All employees will have their focus on achieving the objectives. Having a business plan, will enable an entrepreneur have strategies for the business. Strategies are guidelines meant to lead the business to success. A business budget helps the entrepreneur to asses all the requirements of a business. For example, the required number of employees, machinery and other requirements. Using business plan will enable the businessperson to identify some requirements, which are not obvious[1].

An entrepreneur may want to finance the business using other sources apart from personal income. A Business plan is required to acquire a loan. Investors also need to see the business plan before they commit their investments to the business. It assists them to determine whether the business is viable. Every detail of how the business will be run is contained in business plan. It will act as a guide in case any employee deviates from the goals of the business. It enables the stakeholders to analyze their performance using the objectives. They will make adjustments according the specific objectives of the business[2].

There are key elements of a business plan are an executive summary and the statement of purpose. The statement purpose includes sub topics like business concept, financial features and requirements, market analysis, management and appendix. The executive summary explains the intention of the business. The business desires and what the entrepreneur wants should be in the executive summary. Since it should be brief, it is supposed to be half of a page. The business concept part defines the business in general. It discusses about the products, which will be produced and the target market. It also explains why the business has chosen the product and what will be the benefits of producing it[3].

Financial features and requirements will show vital aspects like expected returns from the business, profitability, cash flows, sales volume. Financial requirements include the capital required to start the business.            Market analysis is about the industry a business will belong. This section should describe the current position of the target market. It should mention the competitive advantage of the business and marketing of products. The management section will show the intended number of employees for the business. It should clearly show how the entrepreneur intends to manage the business. The appendix is an optional section. It explains terminology used in the business plan[4].

A business plan includes a financial plan. It outlines all the requirements and the costs. An estimated budget is created and later an actual budget follows. The estimated budget gives an idea of the money required. An actual budget is made after all figures for costs have been confirmed. A financial plan is important when seeking for funds in loaning facilities. They need to see the amount required by the business. They also need to see how the money will be utilized. A financial plan helps to avoid inconveniences. Since all the requirements are listed, none will be left out hence good planning will be implemented. Unlike when there is no business plan, some vital requirements are left out and later remembered[5].

There are both internal and external users of a business plan. In a vehicle manufacturing company, internal users are employees, managers and the board of governors. They use it for different reasons. For example, it is useful in reviewing the performance of the company. The users go through the objectives and determine whether they are being achieved. The external users are investors and creditors. For instance, the company may need a loan from a bank. The bank will have to use the business plan to approve it. Investors cannot direct their investments to a company without seeing the business plan. Therefore, it is important for a business to have a business plan[6].

Becoming a Great Business Leader

Becoming a Great Business Leader

A great business leader should posses several features. They include self-discipline, willingness to learn, and passion.

SELF DISCIPLINE

Self-discipline is the key to success. It forces you to do things others do not like to do, going the extra mile. In order to become a successful businessperson, it is true that you cannot get anywhere without creativity and vision. However, something even more important than that for the success of a business is self-discipline. Not many could survive without it in today’s business environment. Whenever you are working for your own business, you have the discipline to spend a lot on work, on the least fun parts of running the business. For example, planning, financing, and bookkeeping.

After all, if you want to be your boss, you have to sacrifice your fun time to do something that others will not do. When you are the boss, there is no one there to keep you at work, and there is no one else to force you to do the extra work. There will not be any short-term consequences. But in the long run, you will have to pay the price for skipping work, just to give yourself some time off to do something fun. Some business owners might think that ‘just this once’ will not hurt, and later when ‘just this once’ becomes a daily occurrence, the business has few chances of being successful.

WILLINGNESS TO LEARN

You do not have to hold a secondary education diploma in order to be successful in your business. In fact, many successful businesspersons without a secondary education made themselves millionaires. They have become what they are today, because they are willing to learn. In order to be successful, you will always have questions to ask. You will have to keep yourself interested and always accept new ideas and knowledge. In today’s fast-paced business environment, your original business idea will be constantly changing, given the rapid changes in technologies and ways of doing business. Every little detail or information brings you closer to your goals. Willingness to learn is very crucial in today’s business. As a businessperson, you have to realize the differences between you and your competitors.

Learn from your competitor’s strengths and success, and learn from your own weaknesses and mistakes. To learn means that you will need to change the wrong things you are doing in your business and do what your competitors are doing best. Do not be afraid of failure; fail first and then you can conclude it is the wrong way of doing your business. Learn from your mistakes, move on, and make changes until you get it right. “Ford is today known for his innovative assembly line and American-made cars, he wasn’t an instant success. In fact, his early businesses failed and left him broke five times before he found the successful Ford Motor Company.”(The Henry Ford)

BE PASSIONATE

Be passionate with what you do. Choose something that sparks your creativity, that you enjoy to talk about and puts a smile on your face. Steve Jobs once said, “People with passion can change the world for the better.” He said he would rather work as a bus boy, until when he would figure out what he was passionate about; and passion meant everything to him. (Thursday, B)You cannot simply be successful if you are not passionate about doing what you do.

Success might be easy once you have found out that you love what you do, because it usually motivates us to work hard to achieve our goals about things we love.  Your overall work performance will be maximized and only if you are doing something you enjoy doing and are passionate about. If you are just passionate enough, you will not mind the fact that you spend more than 8 or 9 hours each day to work overtime. Again, it is simply because you truly love what you do.

CONCLUSION

Having a great vision and being creative are important features that a great business should possess, but what is more important for a successful business leader to have is the combination of self-discipline, willingness to learn, and passion. Everyone must have something that he or she is passionate about; just keep doing what you love and you will become successful and get the best result from it. Make sure to always keep learning and accepting new ideas and make appropriate changes accordingly. More importantly, you should always work hard towards your goal.

Tobacco Embryogenesis

Tobacco Embryogenesis

Introduction

Tobacco is considered as one of the most important cash crops due to its huge demand attributed to large cigarette use by people. The reasons behind embryogenesis is the dire need to create plant cultures or types which can be used in large scale commercial farming for sale in tobacco industries whose demand is increasing on a daily basis due to increase in the number of cigarette smokers. The process of studying the various tissue cultures via embryogenesis enables formation of firm conclusion as to the best conditions for maximum production and growth of the tobacco plant. Embryogenesis involves the development of an embryo and the process of facilitating the growth of the embryo. This enables studies on the different types of cultures of tobacco depending on their variability to enable commercial undertakings in the growth of the best types of tobacco by farmer for industrial use in making of cigarettes (Zhihong  & Jiyang, 2008).

Materials and Methods

Various plant regulators were used resulting in various growth issues such as the number of leaves and the size of the plants. Benzyl Amino Purine (BAP), an artificial cytokinin was used to bring out the growth by the development of buds of the tobacco tissue culture. The growth promoted by BAP is in such a way that it enhances the cell division process. Cell division in embryogenesis occurs when the cell is under the interphase to the cytokinesis process when the cells divide into two. After formation of the two cells, the cells develop to form the various plant parts such as the buds, stems and roots. The use of 0.54nm NAA led to the development of more than 15 buds in the calluses and approximately two roots. BAP however contributed to stunted growth and damaged tissues of the plants. In cases where the tissues were worn out or old and with callus, the tissues redeveloped when the BAP was used as it enhanced growth at the point where the tissues were removed. This is because the levels of auxins were low to inhibit any kind of growth as the product inhibits any form of respiration of the kinase chemical within the plant.

The effect of BAP is considered at its lowest in the roots because of the presence of the auxin chemicals, which are attracted to the roots by the forces of gravity. Use of NAA and BAP led to the formation of numerous shoots in comparison to those, which used the TDZ synthetic. Use of huge amounts of NAA led to the stunted growth of shoots as well as the low numbers of shoots. On the other hand, use of TDZ in large amounts had appositive effect because it enhanced the growth at the callus points despite the growth being minimal at the callus points. In addition, the TDZ was ineffective at lower volumes because it did not influence growth at any at the callus points of the tissue cultures.

The use of TDZ was utterly effective when its use was combined with the NAA and the BAP synthetics leading to shoot growth and elongation. TDZ enhances propagation when used in moderation. In addition, it inhibits the morphogenic formation via a negative feedback formation. The negative response is aimed at hindering growth by increase and formation of more ethylene hormone, which reduces the effectiveness of the synthetic chemical. In general, it leads to stunted growth of the shoots roots and the stems because the stems formed are short and thick. In addition, the BAP and the NAA played a significant role in the negative effects of hormones coupled by the presence of auxins, which jostled for space within the plant system leading to stunted or inhibited growth in the tissues of the plants (Srivastava, 2002).

Results

The synthetic regulating chemicals used in their concentrations influenced the outcomes of the growth of the tissues. The most affected tissues with specific reference were the shoots and the roots because they are the points where the chemicals had a tendency to concentrate themselves.

Growth hormones had diverse effects on the shots as wells as the roots of the tissues cultures. This was because of high concentrations of growth hormones inhibit maximum growth of the roots whereas the high concentrations of hormones within the shoots contributed to high bud propagation. The naturally present auxins within the plant contributed to the inhibition of growth at the various plant tissues with specific reference to where the auxins are present such as the meristematic tips and buds, which were developed shoots. On the other hand, the moderate amounts of TDZ used on the tissues enabled the growth of the tissues, which was identical to the NAA and BAP mix (Klerk, Hall & George, 2007).

In addition, the simultaneous use of NAA and BAP proved to accrue the best results because it enabled the formation of approximately 256 shoots and eight plates of tissue cultures. The results achieved were because the two synthetic chemicals used enhanced the formation of the budding process to form, buds as the chemicals hindered the actions of the naturally occurring auxins in the various tissues of the cultures presented for study. The presence of the auxins enables regulation of the hormonal concentrations within the tissues thus promoting growth within the plant. In addition, the lack of the auxins can be translated to the unproportional growth or inhibition of the preferred growth of the various tissues. Furthermore, the presence of high amounts of the synthetic chemical TDZ, which enabled growth of shots without propagation of multiple shoot growth.

In conclusion, the chemicals used all had various effects on the growth of the tissues, which was furthermore influenced by the amounts, or levels of concentration of the chemicals used to control the growth of the tissues. High concentrations of the three chemicals, NAA, BAP and TDZ had negative effects in that they led to stunted growth of the tissues of the tobacco cultures.

Differentiate Criminal Behavior

Differentiate Criminal Behavior

Biological theories

Biological theories about criminal behavior began in the early days when they believed that if you were ugly, deformed or disabled, it reflected your level of criminality. Physiognomy was used in ancient Greece where they looked at your facial structure and could tell whether you were a criminal or not. In medieval Europe, if two people were caught and accused of the same crime, the uglier one would be convicted. Phrenology was also used to identify criminals. It was said that some bumps on the surface of the skull depicted criminal behavior. Lombroso claimed that criminals were physically degenerate. His theory was based on natural selection. More theories on biology claimed that criminality was biologically inherited.

This theory uses the concept of physical appearance and genetics to explain criminal behavior in human beings. For example, the proprietors of phrenology based their arguments on the bumps at the back of the skull that reflected abnormalities of the brain hence criminal behavior. Physiognomists believed that criminals had physical deformities like small ears and large lips. They also believed that physical beauty reflected goodness. Men are said to be involved in criminal activity more than women because of their higher levels of testosterone.

Sociological theories

These theories emphasize the role of social factors in criminal behavior and hoe the society responds to it. There are three main sociological theories of crime; strain theory which states that people engage in criminal activity as a means of escaping bad experiences like poverty, drug addiction. The social learning theory states that criminals learn to engage in crime by associating with other criminals. The last theory is the self-control theory, which states that a person engages in criminal activity for the sake of his or her own pleasure.

Sociological theories use the concept of society and social issues to explain the causes of criminalities in human beings. Some of these issues include young men and women who come from poor families, abusive parents, etc tend to engage in criminal activities to run away from their problems. A person in a poverty-stricken neighborhood who is exposed to drug dealing activities, will himself start dealing because he will want to have as much money and power as the drug dealers.

Psychological theories

These theories are of the view that individual differences may make some people more prone to committing criminal acts. There are three psychological theories, psychoanalytic theory, cognitive development theory and the learning theory. Psychoanalytic theory was developed by Sigmund Freud who said that all humans have natural criminal tendencies. The cognitive development theory says that criminal behavior results from people’s organization of their thoughts about morality and the law. The learning theory illustrates that a person’s behavior is learnt and maintained by its reward value.

The psychological theories are based on concepts of a person’s psychological entirety. For example, children who were wrongly identified by their parents developed personality disturbance that causes him or her to engage in criminal activity later in his life. In addition, when a child does something wrong and his rewarded or praised for it, they will grow up knowing that doing bad things gets them good recognition from the people around them.

Social-psychological theories

This theory is based on the notion that crime results from the lack of self-direction, derisory social roles and involvement with bad role models. For example, a young girl who hangs out with criminals who use her as scapegoat every time they get into trouble. This girl is not being forced into the action, but is doing it willingly. She does not care about what her criminal friends are doing; she chose her own path when she decided to get involved with them. This theory is based on the impact of society on young people’s involvement in criminal activity.

These theories are interrelated in their efforts to explain why people engage in criminal activity. For example, some of the points on biological and psychological theories are closely related. This is because biologically, those with physical deformities suffer from low self-esteem, which may in turn drive into criminal activity. The esteem issues are psychologically developed within that person. Therefore, both theories, though different, serve the same purpose. Sociological and psychological theories are also related in that the man who starts dealing because he wants a flashy life is psychologically affected by the fact he cannot afford it.

Psychological theories are most accurate than all the others in explaining criminal behavior. A good example is given by the fact that a person psychology begins at birth and how that person is brought up determines whether he or she will turn out to be a criminal or not. It is further said that those children that are neglected and mistreated by their parents will most likely grow up with negative personalities and this might lead them into criminal activity as a way of trying to bet affection and attention.

Air Pollutants

Air Pollutants

Define Air Pollutants

Air pollutants are the substances or agents that contribute to air pollution. They can be chemical, physical, biological or radioactive (Reitze, 2001). They can come from natural sources, or they can occur because of human activities. Natural pollutants refer to pollutants that are released from natural sources, such as volcanic activity. Pollutants that occur due to human activities are referred to as anthropogenic pollutants. They occur because of human activities and processes such as the combustion of fossil fuels. Understanding the nature and cause of the air pollutants will help in controlling air pollution. Air pollution is the contamination of the air, and it occurs when the air contains harmful substances such as dust, fumes, and harmful gases and odors in levels that affect human health and the environment. Air pollutants can be primary or secondary.

Primary Sources

Primary sources release air pollutants directly into the atmosphere from sources such as exhaust pipes and factories. The sources can be anthropogenic or natural. Primary pollutants include carbon monoxide, sulfur dioxide, volatile organic compounds, particulates, and nitrogen oxides (WHO, 2006). Primary pollutants do not change their chemical format when they are released in the atmosphere. Controlling primary pollutants from anthropogenic sources is easier than controlling the secondary pollutants or primary pollutants from natural sources because they are controlled at the source.

Secondary Sources

Sometimes, primary pollutants and natural particles undergo chemical and physical changes, resulting into secondary pollutants. Primary pollutants react with other elements, and they produce secondary pollutants. The chemical reaction that occurs when producing the secondary pollutants produces products that are less reactive than the original elements. Increase in temperature, mainly from the heat produced from the sun, increases the reactivity of the products. Secondary pollutants include photochemical smog, ozone, and nitrogen oxides (WHO, 2006). It is difficult to control secondary pollutants because one has to know the chemical processes that took place when forming the pollutants, and the chemical formation of the pollutants, and identify the sources of the pollutants (EPA, 2010).

Major Air Pollutants

Carbon monoxide is one of the major pollutants. It is a colorless and odorless gas, which is harmful to human health. It occurs when there is incomplete combustion of carbon fuels. The complete combustion of carbon containing fuels release carbon dioxide. Most of the carbon monoxide occurs because of human activity. The biggest source of carbon monoxide is the transportation sector because of the exhaust from motor vehicles, and the industries that use carbon based fuels. Therefore, levels of carbon monoxide are highest in areas with many motor vehicles and traffic congestion. Other activities such as wood burning, forest fires, wood and gas stoves, and cigarette smoke contribute to increased levels of carbon monoxide in the atmosphere (EPA, 2010). Carbon monoxide combines with hemoglobin in the body, reducing a person’s oxygen. It reduces the blood supply in the body. It weakens visual perception, limits learning and work ability, and weakens a person’s ability to perform complex tasks (Reitze, 2001).

Sulfur dioxide gas is harmful to human health and it damages other materials. It is released when there is combustion of fossil fuels that contain sulfur. It is therefore prevalent in areas where people use coal as the main source of fuel. Although it is an anthropogenic pollutant, it can also occur because of volcanic activity. Other sources of sulfur dioxide are the industries that use crude oil and metallic ore as their raw materials (EPA, 2010). It has diverse effects on human health, and it affects various organs such as the eyes, lungs, and nose. It intensifies cardiovascular and respiratory diseases, and weakens the lungs’ defenses (Reitze, 2001). Sulfur dioxide is soluble in water, and it forms sulfuric acid when combined with water. This acid can fall to the earth as acid rain, which has negative effects on the environment. It combines with other gases in the atmosphere to form sulfates and other particles, which have negative effects on human health and the environment.

Fossil fuels contain varying amounts of nitrogen, and when burned, they release oxides of nitrogen in the atmosphere. Nitrogen oxides contribute to the formation of ozone. The main sources of nitrogen oxides are motor vehicles and other industries and activities that burn fuels. Nitrogen dioxide is a toxic reddish brown gas, which has a pungent odor. It has negative health effects because it decreases the body’s resistance to respiratory diseases. In high concentration, the gas aggravates acute respiratory disease in children (Rietze, 2001).

The chemical reaction of volatile organic compounds and oxides of nitrogen produce ozone when there is sunlight. The levels of the volatile organic compounds, presence and intensity of sunlight, and nitrogen in an area will determine the ozone levels in that area. However, ozone is transported over wide regions, and this means that it causes air pollution in many areas. When the ozone is present at upper levels on the atmosphere, it forms a layer that protects the earth from ultraviolet radiation (EPA, 2010). Ozone is a major component of photochemical smog. It causes respiratory problems such as asthma, and it impairs and causes inflammation on the lungs. It also reduces the body’s resistance to infections.

Particulate matter refers to heterogeneous mixture of solid particles and liquids in the atmosphere. These particles include soot, smoke and dust. Particulates can be primary or secondary pollutants. Organic chemicals, nitrates, sulfates, and metals contribute towards particle pollution. Some particles are small enough to penetrate the human body. Their effect on human health depends on their size and chemical composition. Some particulates are big and they remain on the ground, while others are smaller and they remain suspended on the air (Reitze, 2001). They enter through the nose and throat, and they reach the lungs. Some particles poison the blood. They cause serious health effects, as they affect the heart and lungs once a person inhales them. These particles can cause permanent damage to the lungs, and they aggravate respiratory problems (Reitze, 2001)

Lead is an air pollutant, and it has adverse effects on a person’s health. Once a person inhales it, it is retained in the body, and it builds up in the blood, bones, and tissues. It damages body organs such as the brain, the circulatory system, and the nervous system. It can also cause mental retardation and behavior disorders. Industries such as metal processing and battery manufacturing contribute to the increased levels of lead in the atmosphere (Reitze, 2001).

Clean Air Act

The establishment of the Clean Air Act enabled the government to reduce interstate pollution. It sets the standards for air quality regulations. It regulates emissions from mobile and stationary sources. It gives more authority to the Environmental Protection Agency (EPA), and this enables it to set the limits on the pollutants permitted anywhere in the country. One of the main objectives of the act when it was established was to ensure that it set the National Air Quality Standards in all the states to reduce the risks of the air pollutants. Although different states can set environmental regulations, they cannot enforce weaker limits than those provided in the act. Since the passage of the act, there has been a reduction in the lead levels in the atmosphere. This is because there is less sulfur on motor vehicle fuel (Raven et al., 2011).

The EPA sets different programs to ensure that the air is free from pollutants that cause acid rain, smog, and haze. It ensures that it eliminates or reduces the chemicals that destroy the stratospheric ozone, and cause diverse health problems. It has identified six criteria pollutants found all over the country, and these include particulate matter, carbon monoxide, lead, sulfuric oxides, nitrogen oxides, and ground level ozone. The agency aims to clean up these pollutants because of the risk they pose to people and the environment. The agency has established measures that will ensure that people are more responsible. For instance, it requires the manufacturers to build cleaner engines, refiners to produce cleaner fuels, and people to maintain their vehicles and other machines in good conditions. This is because the transportation sector accounts for most of the carbon monoxide in the atmosphere. Since the establishment of the Clean Air Act, people have become more aware of air pollution. Environmentalists have discovered the effects of air pollution on people and on the environment. They have discovered various forms of acid precipitation such as acid fog, acid snow, acid mist, and dry forms of acidic pollution. They have discovered the elements that contribute to increased levels of air pollution. This has led to people leading healthier lives and has contributed towards a less polluted environment.

Impact on the Environment

Air pollutants have diverse effects on the environment. They damage the vegetation, ecosystem and buildings. High concentration of air pollutants causes premature early leaf drop (senescence), which can end up killing the plants and trees. The pollutants affect the reproductive cycle of the plants, leading to stunted or reduced growth. The pollutants change the physiological and biochemical processes in plants (Vallero, 2007). They reduce the number of chloroplasts, leading to discoloration of plants. Sulfur dioxide has a negative effect on the environment because it damages trees and agricultural crops such as soybeans, corn, and wheat. It also corrodes buildings. Crops have lower yields when they are exposed to ozone. Ozone has reduced the eastern white pine trees, ponderosa, and Jeffrey trees (Reitze, 2001). Sulfur dioxide is converted to tiny particles, which in turn form aerosols. Aerosols form a haze, which reduces the amount of sunlight reaching the earth’s surface, and this affects visibility. Particulate matter contributes to the formation of smog.

Acid deposition in water bodies leads to the decline of aquatic life because of the changes in the pH levels. High metal content in water bodies is poisonous to aquatic plants and animals. It kills fish and destroys some of the aquatic plants. The lack of calcium in the water and plants affects birds. Birds lay eggs with thin and fragile shells, most of which end up drying out before they hatch. This is because the birds do not get enough calcium (Raven et al., 2011). Animals accumulate air pollutants through vegetation, and not necessarily through inhalation. Acid deposition increases soil acidity, and causes some important minerals to leach out of the soil. This affects plants and it causes decline of some plants and death of others. The effect of the acid on the soil weakens the ability of the trees to tolerate stresses from the environment. This can be disastrous on a large scale because it can cause the gradual destruction of forests (Vallero, 2007).

Acid deposition from sulfur and nitrogen oxides corrodes metals and damages buildings. Ozone oxides many products, and it damages fabrics and rubber materials. Air pollutants damage stone materials. It erodes soils and blackens them. It destroys the monuments made of stone by eroding the details. It forms crusts on these monuments and buildings. Air pollutants corrode metal surfaces, deteriorate the coating, and perforate the surfaces. The pollutants destroy glass items by corroding potash glass and soiling the modern soda glass (Watt, 2009). Therefore, air pollutants destroy the materials made from stone, rubber, wood, fabric, and metal.

Profit and Loss Sharing System v. the Interest System

Profit and Loss Sharing System v. the Interest System

Introduction

Many capitalist countries around the world have adopted the interest-based economic system. The Islamic religion prohibits riba in all its forms. Riba not only refers to usury, which is excessive interest charged on loans, but it also refers to other forms of interest on loans. Some of the Muslims who support and use the conventional banking system claim that interest is not a form of riba. However, a careful analysis of the Quran reveals otherwise. Although many Muslims know this, they continue to exercise different forms of riba. Most economies, even in Islamic countries have become secularized. It has become increasingly hard for Muslims to do business in any other way because they have to depend on the conventional banking system. They are therefore forced to compromise on their beliefs, because they use conventional banks which charge interest on loans, and which pay interest on deposits. Some countries and economies have made the effort of adopting the profit and loss sharing system, which is an interest free system. Although faced with many challenges, this system is more acceptable in the Islamic faith, as it follows the rules set in the holy book, Quran. It is in line with the Islamic legal system of shari’a. Both the interest based system and the profit and loss sharing system have their advantages. However, the profit and loss sharing system is a more efficient in allocating available liquid funds in the economy.

Discussion

The profit and loss sharing is an arrangement that is based on contract between two or more transacting parties. This system enables the parties to pull their resources together, and invest in a project, after which they share the profit or loss realized from the project. This means that the people depositing their money in the bank are not only the banks’ clients, but they also act as shareholders since they have some ownership. The parties involved in the transaction share the risk equitably, depending on the level of participation between the parties. The party providing the finance or the money does not benefit from any interest. Since the investors do not benefit from any interest, the banks and other financial institutions have to find ways to encourage more investors. The mudaraba and musharaka enables the depositors to share in the profits made by the bank. The system is a just way of serving the people because the borrower only needs to repay the amount that he or she had borrowed. In some cases, borrowers repay the money, and they contribute gratuity for the services they have received. It uses a return bearing instead of contracts based on interest.

The interest-based system is not an efficient method of allocating funds in the economy because it tends to rely more on the Keynesian principles and theory. According to the Keynesian theory, the marginal efficiency of investment and the demand and supply for money are vital components to consider when lending money. Most financial institutions finance a project if the marginal efficiency of investment is equal to or greater than the interest rate. The supply and demand of money affects the interest rate. Most of the interest-based systems follow this principle. Lenders cannot finance a project if it does not meet this condition (Ahmad). Lenders offer loans to people that meet the specified condition, and they do not consider the quality, suitability, and profitability of their projects.

The interest-based system is selective and tends to practice favoritism in allocating funds. It treats large corporations and medium enterprises differently. It gives priority to large corporations and it provides them with better borrowing terms (Ahmad). Banks in this system lend to the people they know well or to public enterprises. It does not consider how the different corporations will use the allocated funds. In some cases, banks have incurred huge losses after they gave priority to public institutions, which ended up failing or shutting down. It is therefore important for lenders to consider the quality and profitability of the project, before lending money to an institution. The interest-based system is more concerned with the credit worthiness of an institution. This locks out many individuals and small corporations with viable and profitable projects.

The smaller corporations find it difficult and challenging to get finances from the formal interest based systems such as banks, and they end up seeking financial help from informal interest based institutions such as loan sharks, where they pay very high interests. Even when the conventional banks have allocated some funds to go towards financing small scale and medium scale ventures, the banks put in credit ceilings, cumbersome formalities, and heavy guarantees, which end up discouraging borrowers. When these banks do allocate some funds to the small enterprises, they do not give them enough money to complete and initiate their projects. This has often led to the failure of some of the projects because the money is not usually enough for their business to grow.

Financial Tools

Mudaraba and musharaka are two ways of earning profit while avoiding interest. In mudaraba arrangement, one of the involved parties provides the needed finance capital, and the other party provides the human capital, to perform the economic activity. Mudaraba arrangement is often applied on short-term basis. The entrepreneur utilizes the capital he has received from the investors, and he gives them a pre-specified share of the revenues. He keeps the remaining share as part of the reward for his efforts. This is based on the personal confidence, efficiency, dedication, honesty, and work ethic of the entrepreneur. In case the investment or business venture fails, the investors incur the loss. The entrepreneur’s loss is the time, effort and labor that he spent on the venture.

In musharaka arrangement, partners use their financial capital needed to undertake the economic activity. Partners use the musharaka arrangement on long-term basis. The partners share the profits according to a pre-agreed ratio, but they share the losses according to their proportion of the capital (Hassan and Lewis 51). Since musharaka arrangement is a partnership, all the partners have the right to manage the affairs of the venture. However, this is not mandatory, as the partners can agree to select one or a few members to handle the company’s affairs or the business project. In this arrangement, members have unlimited, and equal partnership. When all the members decide to work together on the project, the decision made by one member is seen as collective agreement. Each member acts as an agent of the other members, or as a guarantor of the other partners.

The profit and loss sharing system increases the number of different investment projects. Other than the mudaraba and musharaka, Islamic banks have developed other financial instruments that comply with sharia. Most Islamic banks have adopted murabaha, because it ensures that they profit from the transaction. The bank agrees to buy the asset from a third party and resells the asset to the client (Hassan and Lewis 52). The concept involves the bank buying the items needed by the entrepreneur, marking up the items, and then handing them to the entrepreneur. The banks mark-up the items with the price of its compensation. The entrepreneur then pays the loan and the mark-up price. Unlike the interest charged at conventional banks, the Islamic banks do not penalize the clients for any late payments, and the mark up price does not increase in value, regardless of the time passed. The markup price represents the services that the bank conducts on behalf of the client. Moreover, the mark up is not based on money lending, but it is based on delayed payment (Hafez 91). This system ensures that the banks are fair and just towards their clients.

Banks can also choose to use ijara, which is the equivalent of a lease in conventional terms. Under this system, a bank buys an asset, which it then leases to its clients at a fee. The bank maintains the responsibility of insuring the asset and making sure that it is maintained properly. The bank can renegotiate the terms of the lease with the client at agreed intervals. This gives the bank a chance to avoid incurring risks because the bank renegotiates the price according to the market rates. Under the ijara wa iqtina arrangement, the client can decide to purchase the asset after the rental period (Hassan and Lewis 52). In ijara, the investors utilize the funds by purchasing a durable asset, which they utilize rather than consume. That means that the leased asset should not be perishable or consumable. The client must use the asset for the purpose it was intended, and he has to follow the provisions in the contract. The client should also benefit from utilizing the asset, in more ways than what is included in the contract. This is because the asset provides a way for the client to pay the agreed lease amount and realize some profits from using the asset. At the end of the lease period, and in the absence of ijara wa iqtina, the client must return the asset to the bank in a good form. The client must pay for any negligence on his part (Iqbal 109-113).

Banks use istisna, where they transact a commodity before they see it. The client requests a manufacturer to manufacture a specific product at an agreed price. Any of the parties involved in the transaction can cancel the order before the work begins. The manufacturer has a moral obligation to manufacture the product once all the parties agree on the terms. The manufacturer has to ensure that the product meets the specification agreed on by all parties to ensure that the client does not retract (Iqbal 117). Another financial tool used in profit and loss system is salaam. Salaam is most often practiced in agricultural economies. The concept of salaam involves the seller, Muslam ilaih, supplying some products, Moslem fih, to the buyer, Rabb-US-Salam, at a future date in exchange for an advance price, ra’sul-mal, which the buyer pays on the spot. In agricultural economies, the bank makes the transactions with the farmers because they expect the farmers to have a harvest at a specific time.

Sukuk is the most recent introduction in Islamic banking. It serves and benefits those who are looking for alternatives to interest-based banking. Most investors interested in financial markets are wary of trading in conventional markets, because the markets associate in the trading of unlawful products such as alcohol. Bond issuance is an accepted way of investing. However, most of the bond trading involves payment and receiving of interest. The sukuk is structured in a different way, in that the investment market bases the bond issue on the exchange of an approved asset, such as infrastructure. All the assets have to comply with sharia law (Hassan and Lewis 53). For instance, investors cannot base their assets on a casino because it involves gambling. Most Islamic governments and corporations use sukuk as a means of financing.

The concept of profit and loss sharing encourages the lenders to find more ways to invest in profitable ventures so that they can avoid incurring any losses. It is a way of allocating the liquid assets available in the economy, as the lenders find ways of investing the assets. Conventional banks are concerned about profitability and loan defaulters. They charge interest to ensure that they remain profitable. The banks remain profitable so long as the borrower keeps paying the interest. This is not a just way of serving people because it continues to depress them financially. The conventional banking system does not consider the financial situation of the entrepreneurs, and will require them to pay interest even during financial and economic difficulties. Islamic financial institutions depend on the returns of their physical investments. Their profitability depends on the real rate of return.

Risk Management

Profit and loss sharing systems have a better way of managing risk, and they provide better financial stability. Investors are cautious and more selective concerning their investment projects, and this reduces the financial risk and chances of incurring losses. Many countries around the world suffered during the financial crisis that began in 2007. This was especially the case in most interest-based economies. The profit and loss sharing system ensures that both the person providing the capital and the person receiving it share the risks. The lenders consider the borrower’s financial state during periods of economic crisis. The rate and state of payment are flexible, and lender adjusts them according to the economic situation. Borrowers pay smaller amounts of their loans during hard economic times. The same concept does not apply in interest-based system. There is poor risk management in interest-based system.

Partnership and Trust

The profit and loss sharing system encourages partnership between the parties. It encourages the lenders to build a long-term relationship with the borrowers. The lenders are able to advice the borrowers concerning profitable ventures, and the financial economy. This is generally good for the economy because it ensures that businesses remain profitable. There is less financial risk and implications during periods of economic meltdown. In interest-based system, the borrower bears a larger part of the risk involved. This is different in the profit and loss sharing system, where the lender incurs the risk. Although this may mean a loss to the lender, it ensures accountability and responsibility on the part of the lender. The lender is more cautious and makes better investment decision because he or she does not want to incur any losses. Lenders are more careful about where they invest their client’s money. It also eliminates any chance of greed on the lender’s part. In most conventional banks, the lenders are more concerned about profits and some are greedy for more money. They look for risky ways of investing so that they can make more money. The profit and loss system eliminates this option.

Better use of money

The concept of Islamic banking and the profit and loss sharing mechanism ensures that borrowers use the money they borrow for their intended purposes. This instills accountability on the borrowers’ part. It ensures that the borrower will use the money for business, which will enable him to repay the money. The banks follow the entrepreneur’s business to ensure that it is in operation and that it is realizing some profits. In conventional banking, borrowers are sometimes tempted to use money for other reasons, other than the ones they had indicated when they were applying for the loans. In most situations, banks do not follow the borrowers, since they are mostly concerned about the loan and interest repayments. The borrowers can use the money in whatever means they choose, so long as they find ways of paying the interest. This has led to an increasing number of loan defaulters, and it has led to huge losses for the banks since they have to write off some of the loans.

Economic Development

The profit and loss sharing system is one of the most effective ways of ensuring economic development. This is because it provides loans to profitable projects, despite a person’s financial status. Banks are more interested in the quality of the proposed project in terms of profitability, and the integrity of the client, rather than the securities that the client can provide (Hafez 90). The bank does not deny a person with a profitable project a chance to pursue the project because it will share in the profits. Most conventional banks are concerned with short-term profitability. In most cases, they do not give loans to people with projects that seem to have a long gestation period. Conventional banks often depend on the client’s record of accomplishment in deposits and loan repayments, before deciding to give the person a loan. This does not happen in the profit and loss sharing system. This means that Islamic banks tend to encourage and support more entrepreneurial development than conventional banks (Hafez 90).

Conclusion

The profit and loss sharing system utilizes many financial tools, which helps it to allocate liquid assets effectively. These financial tools include salaam, istisna, ijarah, murabaha, mudaraba, and musharaka. These financial tools comply with the Islamic legal system of shariah law. They are not based on interest, and they are fair and just to the clients. The financial tools ensure effective allocation by investing the funds in many different projects. The interest-based system is not as effective as the profit and loss sharing system. Not only does it exploit the people by charging interest, but is also risky, and it does not have an effective way of allocating liquid funds. The main goal of the interest based system is to make a profit by charging the clients interest. The profit and loss sharing system is a good way to grow the economy because it assists people with profitable projects. The interest-based system is prejudiced because it tends to favor wealthy individuals and large corporations. On the other hand, the profit and loss sharing system ensures that it allocates the funds to all the people in need irrespective of their credit-worthiness or status in society. These factors make the profit and loss system the most efficient way of allocating the liquid funds in an economy.

Langston Hughes Poems And Themes Contrasted

Introduction

The poems I, Too and Theme for English B are written by Langston Hughes. He was of American decent. Most of his work was done during Harlem Renaissance. He was among the innovators of writing poetry in jazz art. The most famous work was called Harlem was in vogue. Apart from being a poet, he was a social activist, columnist, playwright and novelist. He lived between the years of 1902 to 1967. I, Too and Theme for English B have similarities and difference emerging in themes as well as structure (Hughes, Rampersad & Roessel, 55).

Discussion

There is a similarity in the both poems while addressing the theme of racsism. In I, Too, the persona is maltreated because she has colored skin. When visitors come to their home, he is sent to eat in the kitchen. The African Americans were discriminated because they were considered inferior. Initially, they lived as slaves and it could be the reason white people developed a negative attitude towards them. After abolition, they were faced with the challenged of racism. The poet was addressing this issue because it was a major challenge towards the black Americans.

Theme for English B talks about racism in learning institutions. The persona is discriminated because he is a black student in school dominated by white people. He seems not to understand because race does not determine personality or intelligence. He gives an example and says his instructor could also learn from him regardless of his color and age. He continues to say him and the instructor are part of each other. They have a student-teacher relationship and it should not be affected by their races. White people did not like to be associated with the blacks. This is why the persona said he understands when his instructor does not want to be seen as part of him (Hughes 99).

Both poems have a theme of hope for the African Americans. I, Too poem talks about the future being better. The persona will not be chased off into the kitchen anymore. He will dine at the table even when there are visitors. They will see how beautiful he is and become remorseful about their ill treatment. This shows the black people were hopeful about the future. I knew that racism will end and the law will protect their right of living in a peaceful society. The persona argues she is an American too, who should have equal rights to those of whites and get fair treatment.

In Theme for English B, the persona was the only black student in class. This was a good sign of hope because initially white and black students would not mix in one class. This shows that in future, blacks would attend any school without being discriminated. This is actually the case in modern America. It is illegal to deny any citizens his or her rights because of or race gender. The persona gets some hope when he remembers Harlem and New York City in general. This is because when the poet was a young adult, there was a movement in Harlem, supporting black people development. He becomes hopeful when he thinks of his hometown (Hughes, et al, 112).

Other resemblances occur in the styles used to write the two poems. Both poems have used symbolism. I, Too poem has used symbols like kitchen, dark brother and tomorrow among others. The persona is sent to the kitchen when visitors come. The kitchen represents mistreatment and discrimination. A kitchen is not an appropriate place to dine. It is lonely and unfriendly. Dark brother symbolizes the African American race. The persona is undermined because of his colored skin. Tomorrow is the future for blacks. The persona believes that in future discrimination will end and there will be harmony between white and black people.

Symbols in Theme for English B are instructor, Harlem and class among others. The instructor teaches the persona English and represent white race. He told the class to write about their thoughts. The persona wrote about how the teacher discriminated him. Harlem signifies hope for the black race. They were vigilant on civic participation because they wanted to be considered as part of America. The class represents how the blacks were denied the right to have basic requirements like basic education in good schools. The persona was the only African American in that class (Hughes, Rampersad & Roessel, 125).

.

There is a parallel of repetition in both poems. I, Too has repeated the phrase, “When company comes”. The poem intends to create emphasis on a situation of ill treatment. Every time visitors visited their home, the dark brother was sent to dine in the kitchen. The use of the words “dark brother,” mean he is human just like whites, only that he is being discriminated for his race. Theme of English B has repeated the word “hear.” It is used to emphasize the persona’s thoughts of Harlem. The persona uses this word to express his nostalgia of Harlem. He is proud of his hometown because it is transforming and fighting hard tom end racism.

The two poems have irregular structures in their stanzas. The stanzas have different number of lines. I, Too poem has five stanzas and they all have different number of lines. The first and last verse of the poem has one line. The second stanza has six lines, the third has seven lines and the fourth has three lines. Theme for English B poem has three stanzas with differing number of lines. The first and last stanzas have one line. The second has four lines, the third has ten lines and the fourth has twenty-four lines (Hughes, 187).

I, Too and Theme of English B poems have differences in their themes, styles and structure of the poem. The former poem has themes that differ from the latter poem. It addresses the theme of education. The persona is a college student studying in a foreign land. He is the only African American students in the whole class. This is an indication of how rare it was for black people to get higher education. The few who managed to pursue college education experienced a difficult social life because of racism. Basic education facilities were limited and had poor facilities and quality of education.

Both poems have different structures of how they have been composed. I, Too poem has five stanzas and eighteen lines. Theme for English B is made of three stanzas and forty lines. This poem has used direct speech, unlike I, Too. The person intends to a good future when racism is over. When visitors come, no one will chase him to eat in the kitchen (Hughes, Rampersad & Roessel, 143).

There is also use of alliteration, which is not found in I, Too poem. The eighth line has used letter “h” in the words there, then. There is use of rhetoric questions in Theme for English B. The rhetoric question addresses whether it will be easy for the persona to express her thought as the instructor said. This is because it could be difficult for a student to confront his teacher about his actions.

Conclusion

Langston Hughes is inspired to write this poem by his background. He come a family lineage of mixed race members. He was unhappy about the discrimination since it caused lack of harmony among the society member. This is why he strongly rebuked it and showed there should be equality between white and black people. The Harlem Renaissance is another inspiration to his works. Efforts of such social activists have helped America to reach its current level of development. National cohesion and coexistence has enabled people to develop the nation (Hughes et al, 167).

Political Economy of Growth and Development

Political Economy of Growth and Development

In his book, Sustainable Prosperity in the New Economy? Business Organization and High-Tech Employment in the United States, William Lazonick speaks about many issues that are highly relevant in the world today. William had a passion for business and economics but decided to delve into the world of human resource studies, organizational behavior and labor relations. These form the principal themes of his book. Williams’ book derives information from real-life situations where the basic economic principles have failed societies in the past as well as presently. The storyline is based in the United States but with a focus on the economic sector. Much of William’s work was historical and sought to enlighten readers on the economic decisions made by former leaders that had an impact on the current economic order within United States of America.

Labor

One of the principal themes that William talks about in his book is the position held by the labor force in relation to the US economy. The liberalization of America’s economy created a new world order in which all economic activities were left to the dogs. The labor sector was among those worst hit by this new approach of letting the market forces of supply and demand run everything. The result of this was increased innovation that catapulted the rise of the new economy that was based on advances in information and communication technology. This was the backdrop for the inception of the Silicon Valley and other ICT hubs. According to William, the market forces were partly to blame for the condition in which American middle-income and low-income laborers have found themselves.

While this New Economy Business Model (NEBM) was hailed by most of America as the commencement of prosperity, William saw in it the beginning of the end. Americans were increasingly unable to reconcile innovation and equity as the rise in the stock market prices was accompanied by higher unemployment rates. William writes that even though the ICT sector offered many employment opportunities particularly for white-collar educated workers, this was paralleled by a simultaneous decrease in quality jobs for workers in the high school level of education. Furthermore, he states that the increasing job insecurity was becoming a dominant feature in the US economy. Most ICT companies were relocating and transferring their high-skilled workers to low-wage locations (Lazonick, 2009). Quoting a study done in 1973 all the way up to 2006, the results showed that members of the U.S. labor force experienced shorter job tenures. Education and job experience suddenly did not guarantee one employment security.

The labor force within America during the inception of the New Economy Business Model also faced minimal benefits from their various firms who sought to minimize employee costs. Most New Economy companies such as Microsoft, Oracle and Dell were cited by William as offering minimal insurance cover as well as investment plans. The recession setting in at around 2001 only served to increase the demise of the labor force in America. Most firms began to layoff their employees as a strategy to ensure profitability. William cites Hewlett Packard as an example of such a firm. HP announced that it would chop 6,000 jobs and later sent packing around 4,000 employees. In September, HP announced its merger with Compaq, which resulted in further downsizing. All these unemployed workers had little hope of getting jobs elsewhere.

Douglass North also shares similar sentiments in his book, Structure and Change in Economic History, when it came to the investigation of the impact that new technologies had in shaping the economic institutions. In particular, Douglass analyzed the system of property rights, and how conducive it was to investment and technological change. Similarly, he discusses the different market forces that constitute the economic systems. Douglass, however, focused on the distribution of scarce resources that oversaw the development of the system of property rights. He attributes the different economical events that have occurred over time to the arrangements by individuals and groups alike to deal with the insatiable need f managing scarce resources.

Therefore, these two writers, Lazonick and Douglass both had similar thoughts when it came to explaining the ICT phenomenon that revolutionized the old economy businesses into institutions that had different priorities, interests and techniques. They both agree that the labor force was directly affected by the change in the job security receded significantly as well as erosion of other employment benefits for example healthcare and retirement packages.

Organizational change

William Lazonick also speaks at length about the change in the organizational structures. William mainly compared OEBM and NEBM’s different ways of operations. The New Economy brought with it greater horizontal and vertical mobility of labor as high-tech labor moved from one company to another. Most start-ups that mushroomed around this period did not really hold out the expectation of employee security and opted for employee stocks to attract well-educated and experienced personnel. These stock options completely eroded the idea of employee security as they were use to attract and retain skilled staff.

The prime function of stocks was transformed to “manage inter-firm mobility on the labor market by attracting and retaining labor” (Lazonick, 2009, 52). Most of the OEBM adopted new employment practices like mobile retirement schemes that only served to increase the labor –market insecurities. In terms of employment preferences, IT firms chose to hire cheaper, less competent executives while at the same time, sending highly trained workers to offshore branches that were relatively inexpensive and paved the way for these cheaper employees.

Inequitable and unstable economic growth

The United States economy is predominantly dominated by the numerous business corporations who employed over 30.9 billion people worldwide. Therefore, the executives decide on the allocation of resources that in turn have an impact on innovation and income distribution. The decisions to invest a particular way rest on the judgments of these executives in control. The financialized corporation of America draws from the above definition where top executives view the business as a financial asset from which value can be extracted. Profit maximization could be transformed into rent-seeking activities through the concept of stock buybacks that perpetuate inequity and instability in the US economy.

William investigated the high stock price yields that occurred during the 1990 stock market boom and discovered that it was mainly attributed to the manipulation of the distribution of income in favor of shareholders. Manipulation occurs when the top executive who control the resource allocation distribute it in a manner that increased their earnings per share. This was in a case where there was no innovation and speculation by stock market watchers. Most NEBM companies however not only manipulated their stock but reinvested almost all their profits and only depended on their innovation.

According to Lazonick, it is the NEBM companies who engaged in intense repurchase of stocks as a solution to offset the dilution from their stock option programs. Most executives claimed that buybacks were their way of investing in the company thus showing a confidence in the future of the company. Doing this would mean that the stock will be sold by the company at a higher price in order to gain profit which is never the case. Instead, in the 1990 boom, corporate executives acting as personal investors sold their own stock to reap speculative gains. The fall of OEBM and the consequent replacement by NEBM was the key reason for the trend towards greater employment instability and income inequality. The NEBM companies that took over like Microsoft, Intel and Oracle shifted their employee relations strategy from the traditional life-long employment system with full pension to a focus on mobile employees and portable pension systems (Lazonick, 2009, 33). A prime cause of the growing inequity and instability in the US economic system therefore is the stock-based compensation of the executives who run the nation’s leading industrial and financial corporations.

Peter Lindert’s thoughts on the nature of redistribution of incomes in society are quite similar to that of Lazonick’s’. In his book “Growing Public: The Story: Social spending and economic growth since the Eighteenth Century”, However, Peter discusses the redistribution process as being a constraint on the realization of economic growth. This is where he and Lazonick differ. William Lazonick categorically condemns the inequality present in America as resulting from skewed distribution of resource by the top executives of major corporations. Lindert, on the other hand, argues that it is the social policies that hinder growth and development. Placing his blame on social spending, Lindert expounds on his two paradoxes: the “Robin Hood” and “free lunch” paradox. These are theories on the correlation between poverty and social spending. His other nine findings mirror his whole paradigm as explained above (Lindert, 2004).

Globalization

Lazonick also compared the OEBM and the NEBM in terms of globalization. While OEBM had companies that tended to locate branch facilities within their domestic jurisdiction, NEBM invested more in global value chains that provided them with the major part of their revenues. OEBM had no real incentives to go international apart from an interest to reduce losses arising from tariffs or to reduce transportation costs. Multinationals that could venture outside their boundaries were almost exact replicas of their mother companies. However, under NEBM, most companies are in a hurry to go overseas with the biggest targets being China and Asia. Malaysia, Hong Kong, Taiwan and the other less developed countries were the target of startup ICT firms that sought new, untapped markets.

The United States tariff policy was partly to blame for this offshore movement as the state literally promoted multinational activities. Section 806.3 of the Tariff Schedule permitted goods that had been exported from the US for foreign assembly to be imported with duty charged only on the value-added abroad (Lazonick, 2010). The United States also encouraged immigrants to work and live in America under specific regulation. However, the criterion used to select who migrated to America was based largely on competence in computer-related fields. The new work force that invaded the streets of USA brought down the value of labor as it was now in surplus.

Mancur Lloyd Olson was a scholar who did numerous studies on institutional economics. Much of his works bordered on the role of private property, taxation, public goods and contract rights in economic development. In his book, “The Rise and Decline of Nations”, Mancur explains states economic life cycles. In it, he tries to explain the reasons why states struggle, prosper, and eventually flounder. He categorizes his work into these three stages. First, interest groups form over time to influence policies to their advantaged. These policies are obviously protective of their interests, and they will end up harming economic growth. The public however will have little or no resistance, as the interests are pushed by a strong minority, and they will therefore stay. As time progresses, these interest groups coalesce and pull the nation into a possible recession.

Mancur tends to agree with Lazonick on the joint effort of the strong minority who use lobby groups or other associations to influence policy. Lazonick’s illustration of a league of top executives who determine the allocation of resources is quite similar to this. The two scholars both acknowledge the influence that the corporate groupings have on the economy. They also both agree that profit maximization is the number one priority for the firms that can be seen in their pursuit of increased revenue. In doing so, they neglect other forms of service to the society like ensuring health security for their employees (Mancur, 1982).

In the final chapter of this work, he suggested that his argument could lead to an overturning of the “orthodox” theory of pressure groups that saw them as a positive force for democracy and efficiency. Special interest groups representing small numbers of firms in oligopolistic industries could support monopolistic or protectionist legislation. Such legislation could damage the broader economy, especially groups unable to organize themselves that would then have to “suffer in silence.” While he rarely used the term, this argument can be seen as foreshadowing the later theory of rent seeking, and in his later works, he more openly recognized the affinity of his ideas with the public choice school of thought. The sixth chapter, “Inequality, Discrimination and Development,” moves to history and the less developed world, blaming stagnation in pre-Communist China on the entrenched power of strong guilds and the stagnation of India on its caste system, despite the highly laissez-faire system that the British maintained there during the Raj (Mancur, 1982).

Gregory Clark in his book “A Farewell to Alms: A Brief Economic History of the World”, discusses the income disparities that exist between individuals, groups and states within the world. Clark tries to explain the reason for industrial revolution in England based on cultural change. He states that it was cultural and not institutional change that led to the development of economic habits of hard work, rationality and education. His particular focus was on the Industrial Revolution which many scholars credit as having originated from England. This forms one of his topics of analysis as he tries to understand the reason why only England realized this fast economic growth (Clark, 2007).

Lastly, Stanley L Engerman and Kenneth Lee Sokoloff both discuss a similar topic to that of Lazonick’s. Their main theme revolves around the differences in the degree of inequality in wealth, human capital and political power. Also interested in institutional factors that affected economic growth, Sokoloff in his book, discussed alongside Engerman, the impact of countries initial factor endowments. They used this framework to analyze the prosperity of USA and Canada in the late 19th Century (Engerman & Kenneth, 1994).

Conclusion

Business enterprises have a mandate to transform their knowledge base into affordable products for the masses. In order for this to happen, firms need to incorporate organizational learning into their investment strategies. The NEBM has effectively excelled in remaining competitive within the global environment; a feta which would have been impossible with industries using OEBM. However, in Terms of equity, stability and economic security, OEBM has surpassed NEBM in performing collective business functions. With the increased presence of the state in economic affairs, most of these neglected functions have been taken up by the government. The state is once again ensuring employment security and retirement security by implementing welfare programs, ensuring health security as well as other benefits.
