The legalization of marijuana bad for the US Essay
The legalization of marijuana bad for the US - Essay Example One of such arguments was on legalization of marijuana in the United States. The issue of legalization of marijuana is very common and its legalization has remained a significant issue during the US history and has continued to remain one until today. Analysis has indicated that it was first brought in the country during the late 17th century, and since then, it has become a habit of huge number of people in country. In the result, advocates of marijuana argue that people use marijuana illegally; however, legalization of marijuana will allow the government to earn taxes against its selling. On the other hand, opponents believe that its legalization will encourage its utilization that will be harmful socially, as well as ethically. On this issue, my side was of the opponents that legalization of marijuana in the United States is an awful perspective and will be harmful for the country. Fortunately, I was able to convince my gathering, as I put efforts by taking a Rogerian approach that included discussion of both sides of the issue and then focusing on my side with evidence, whereas, Toulminââ¬â¢s approach of the argument would have resulted in disappointing outcome. In particular, Rogerian approach of argument is my usual style of argument, as it allows the reader/listener to know perspectives about both sides, and it allows the individual to acquire confidence of the public that makes easier to convince the

The Effect of Workplace Conflicts on Productivity Essay
The Effect of Workplace Conflicts on Productivity - Essay Example Labour is one of the crucial factors of production, providing the necessary link between the raw materials, other factors of production, and the final products, their distribution and delivery to the final consumer. In simple terms, labour, otherwise known as workforce, comprises of all the various players including employees, their employers, managers, self-employed people, and in a sense, the unemployed population capable of providing labour (Reddy, 2004: 27). Though different perspectives have been taken, the argument that conflict in the workplace, in any of its forms, is not an important barrier to productivity nor is it an interesting topic for economic theory can be challenged. In several dimensions, work place conflicts have become normalities and facts of life. Diversity of opinions, which results from increasing labour in a workplace setting has contributed to different goals and objectives, which conflict in one way or the other. It can be argued from theoretical perspecti ve that though perceived negatively, conflicts in workplace are not at all times a negative thing. For as long as resolutions are effectively executed, chances of both personal and professional growth in the organization within which the conflicts exist can be promoted. However, management failure and evident reduced productivity have become the most common outcomes once an organization is faced by conflicts (Gramberg, 2006:68). Many of the factors that cause these conflicts are developed from within the organization. Through publications, several factors have been noted as the core contributors of workplace conflicts. For instance, poor wages by employees contributes immensely to these conflicts. Although workers have given their time and labor to contribute to the organizationsââ¬â¢ progress, their efforts have not been reciprocated. As a result, they do not feel motivated. Though scholars believe that the result of reduced motivation is reduced output, which consequently reduc e productivity (Maravelas, 2008:14), the magnitude of the reduced productivity is not in any way negligible hence considered a factor to reduced productivity. Another factor contributing to workplace conflicts and believed to lower productivity is poor working condition. Companies that have recorded continuous growth from time to time have evidenced excellent working conditions, which include insurance and medical cover for all workers. When this covers are provided, workers feel part of the company or organization and feel protected at the same time hence productivity increases through increased individual output (Maravelas, 2008:69). Within organizations, bullying has taken place where by some individuals are considered less than others are. This trend still occurs during making of decision affecting the organizations. Whereby theorists advocate that all workers are involved in the process of decision-making, this is not the case. Management makes all the decisions on behalf of ot her people in the organization, including the decisions that affect the employees. Such a state is a form of bullying hence workers feel that they have been considered inferior and as a result relax in their work hence due to conflicts that result as they fight for their rights. This eventually leads to reduced produc

Functions of the Immune System | Dengue Fever Immunity
Functions of the Immune System | Dengue Fever Immunity The function of the immune system is to keep contagious microorganisms, such as definite bacteria, viruses and fungi, out of the body, and to demolish any infectious microorganisms that do attack the body. The immune system is completed by a complex and imperative network of cells and organs that guard the body from infection (1). The organs of the immune system are called the lymphoid organs, which have an effect on growth, development, and the free of lymphocytes (a confident type of white blood cell) (2). The lymphatic vessels and blood vessels are main parts of the lymphoid organs, because they transmit the lymphocytes to different areas in the body and from different areas in the body. All lymphoid organs play a task in the making and also activation of lymphocytes. Layered Defense Organisms are protected by the immune system from infections with layered defenses of rising specificity. If these barriers were breached a pathogen, the innate immune system provides an immediate, but non-specific reaction. All plants and animals have Innate immune systems (3). If pathogens effectively evade the innate response, vertebrates have a third layer of protection, the adaptive immune system. The innate response activates the adaptive immune system. Surface Barriers The body of the human continuously faces attack from foreign invaders that can cause disease and infection. These invaders sort from living microbes , such as fungi, bacteria, parasites, and viruses, to dead toxins, drugs, and chemicals. As our luck, the body has many internal and external defenses that avoid most dangerous attackers from entering and causing damages. The physical layers that stay them at inlet commonly are referred to as the bodys 1st line of defense. The largest body organ is skin; is presents both a physical and also a chemical barrier against the outer environment. The skin makes a defensive cover that completely encloses around the body, shielding blood vessels, muscles, nerves, bones and organs. When tears or cuts in the outer surface of the skin, present an opening for infective organisms, glands under the skin, produce an enzyme that helps to destroy bacteria (4). Although areas of the body not covered with skin, do not unprotected. Mucous membranes, the wet layer of the respiratory system. They produce mucus, a sultry substance that catches irritants that enter through the nose. Innate immune system The cells that mediate immunity embody neutrophils, macrophages, and natural killer (NK) cells, giant lymphocytes that are not T cells but are cytotoxic. all these cells answer macromolecule and saccharide sequences distinctive to microorganism cell walls and to alternative substances characteristic of growth and transplant cells. They exert their effects by means of the complement and alternative systems, with the cells they attack oftentimes dying by osmotic lysis or cell death (5). Their cytokines also activate cells of the nonheritable immune system. a vital link in immunity in Drosophila melanogaster is a receptor supermolecule named toll, that binds plant life antigens and triggers activation of genes cryptography for antifungal proteins (6). Humeral and Chemical Barriers Some microbes penetrate the bodys protecting barriers and enter the interior tissues. There they encounter a variety of chemical substances which will stop their growth. These substances embody chemicals whose protecting effects are related to their primary perform within the body, chemicals whose principal perform is to harm or destroy invaders, and chemicals made by present bacterium (7). Inflammation Inflammation is one in every of the primary responses of the immune system to infection. The symptoms of inflammation are redness, swelling, heat, and pain, that are caused by augmented blood flow into tissue. Inflammation is made by eicosanoids and cytokines, that are released by livid or infected cells (6). Eicosanoids embody prostaglandins that manufacture fever and the dilation of blood vessels associated with inflammation, and leukotrienes that attract bound white blood cells (leukocytes). Common cytokines embody interleukins that are chargeable for communication between white blood cells; chemokines that promote chemo taxis; and interferons that have anti-viral effects, like motion down supermolecule synthesis within the host cell. Growth factors and cytotoxic factors may additionally be released (7). These cytokines and alternative chemicals recruit immune cells to the site of infection and promote healing of any broken tissue following the removal of pathogens. Complement System The complement system is a organic chemistry cascade that attacks the surfaces of foreign cells. It contains over twenty completely different proteins and is called for its ability to complement the killing of pathogens by antibodies. Complement is that the major humeral element of the innate response. several species have complement systems, as well as non-mammals like plants, fish, and some invertebrates (8),(9). Cellular Barriers Leukocytes (white blood cells) act like independent, acellular organisms and are the second arm of the innate immune system. The innate leukocytes embody the phagocytes (macrophages, neutrophils, and nerve fibre cells), mast cells, eosinophils, basophiles, and natural killer T cells. These cells identify and eliminate pathogens, either by attacking larger pathogens through contact or by engulfing so killing micro organisms (10). Adaptive immune system Lymphocytes are available in 2 major types: B cells and T cells. The peripheral blood contains 20-50% of current humorocytes; the rest move within the lymph system. Roughly eightieth of them are T cells, V-day B cells and remainder are null or undifferentiated cells. Lymphocytes constitute 20-40% of the bodys WBCs (6). Their total mass is concerning an equivalent as that of the brain or liver. (Heavy stuff ) B cells are made within the stem cells of the bone marrow; they manufacture protein and superintend humeral immunity. T cells are non antibody-producing lymphocytes that are also made within the bone marrow but hypersensitised within the thymus and constitute the idea of cell-mediated immunity. the assembly of these cells is diagrammed below. parts of the immune system are changeable and may adapt to raised attack the invasive matter (11). There are 2 fundamental adaptive mechanisms: cell-mediated immunity and humeral immunity. Lymphocytes A white blood cell is a style of white corpuscle present within the blood. White blood cells help defend the body against diseases and fight infections. when the overall defense systems of the body have been penetrated by dangerous invasive microorganisms, lymphocytes help give a particular response to attack the invasive organisms (12). Killer T cells A large differentiated t cell that functions in cell-mediated immunity by attacking and essential amino acid target cells that have specific surface antigens (6). also known as cytotoxic t cell, killer cell. Helper T cells Any of varied T cells that, when stirred up by a particular matter, unharness lymphokines that promote the activation and function of B cells and killer T cells (13). B Lymphocytes and Antibodies A b cell identifies pathogens when antibodies on its surface bind to a particular foreign matter. This antigen/antibody advanced is preoccupied by the b cell and processed by chemical process into peptides. The b cell then displays these substance peptides on its surface MHC category II molecules (14). this combination of MHC and matter attracts a matching helper t cell, that releases lymphokines and activates the b cell. because the activated b cell then begins to divide, its offspring (plasma cells) secrete scores of copies of the protein that recognizes this matter (12). different adaptive immune system The alternative adaptive immune systems in vertebrates have several similarities, but dissent therein Lucien-rich-repeat (LRR)-based variable white blood cell (VLR) receptors are employed by bone vertebrates versus the Ig-based TCR and BCR employed by jawed vertebrates. bone vertebrates have 2 VLR sorts, VLRA and VLRB, the various repertoires of that are expressed by separate lymphocytes populations (15). Immunological Memory the capability of the bodys immune system to recollect AN encounter with AN matter owing to the activation of B cells or T cells having specificity for the matter and to react more swiftly to the matter by means that of these activated cells during a later encounter (6). Passive memory Newborn infants have no prior exposure to microbes and are particularly prone to infection. many layers of passive protection are provided by the mother. throughout pregnancy, a selected style of protein, called IgG, is transported from mother to baby directly across the placenta, so human babies have high levels of antibodies even at birth, with an equivalent vary of matter specificities as their mother. Breast milk or colostrums also contains antibodies that are transferred to the gut of the baby and defend against microorganism infections until the newborn can synthesize its own antibodies (16). Active memory Long-term active memory is nonheritable following infection by activation of B and T cells. active immunity also can be generated by artificial means, through vaccination. The principle behind vaccination (also known as immunization) is to introduce AN matter from a microorganism in order to stimulate the immune system and develop specific immunity against that specific microorganism while not inflicting malady associated with that organism (17). Disorders of Human Immunity Some of the most devastating disorders which will affect the humanity are those that attack the very weaponry weve got against diseases, our immune system (7). These disorders can vary in severity from inflicting small rashes or a stuffy nose, to attacking important organs throughout the body, inflicting death. they can also come back from a variety of sources from the genetic passing down of traits, to infection from a malady. These immune system disorders comprise four categories: immunodeficiency, autoimmune, allergic and cancer. Immunodeficiency An immunodeficiency disorder is one in every of the many disorders that attack the immune system. In these disorders the immune system has problems that cause the system to not work correctly. again and again this can be owing to a genetic trait or congenital disorder (6). the most common immunodeficiency disorders are severe combined immunodeficiency (SCID), also known as bubble boy disorder, Di St. George syndrome, and ig A deficiency (18). Motor vehicle Immunity Autoimmune disorders attack the immune system by tricking the body into thinking its own organs are foreign invaders. when this happens, the phagocytes and lymphocytes activate healthy tissues and organs and destroy them. Common autoimmune diseases are lupus, scleroderma, juvenile dermatomyositis and juvenile rheumatism. The severity of AN disease can vary dramatically (19). Some could only cause localized swelling and inflammation by attacking the tissue within the joints, while others could cause death by attacking important organs. Hypersensitivity Hypersensitivity refers to excessive, undesirable (damaging, discomfort-producing and sometimes fatal) reactions made by the traditional immune system. Hypersensitivity reactions need a pre-sensitized (immune) state of the host. Hypersensitivity reactions is divided into four sorts: type I, type II, sort III and kind IV, based on the mechanisms involved and time taken for the reaction (20). Physiological Regulation Hormones can act as immunomodulators, sterilisation the sensitivity of the immune system. as an example, female sex hormones are famous immunostimulators of both adaptive and innate immune responses. Some autoimmune diseases like autoimmune disease strike women preferentially, and their onset typically coincides with pubescence. in contrast, male sex hormones like testosterone seem to be immunosuppressive. alternative hormones appear to control the immune system yet, most notably luteotropin, endocrine and alimentation (21),(22). Manipulation in medication The response is manipulated to suppress unwanted responses ensuing from autoimmunity, allergy, and transplant rejection, and to stimulate protecting responses against pathogens that mostly elude the immune system (see immunization). immunosuppressive drugs are used to control autoimmune disorders or inflammation when excessive tissue harm occurs, ANd to stop transplant rejection once an transplantation. anti-inflammatory drug drugs are typically used to control the effects of inflammation. Glucocorticoids are the most powerful of these drugs; but, these drugs can have several undesirable facet effects, like central obesity, symptom, osteoporosis, and their use should be tightly controlled (23). Lower doses of anti-inflammatory drug drugs are typically used in conjunction with cytotoxic or immunosuppressive drugs such asmethotrexate or Imuran. Cytotoxic drugs inhibit the response by killing dividing cells like activated T cells. However, the killing is indiscriminate and alternative p erpetually dividing cells and their organs are affected, that causes harmful facet effects. immunosuppressive drugs like cyclosporine stop T cells from responding to signals correctly by inhibiting signal transduction pathways (24). What is dengue fever? Dengue fever is a malady caused by a family of viruses that are transmitted by mosquitoes. its AN acute malady of sudden onset that typically follows a benign course with symptoms like headache, fever, exhaustion, severe muscle and joint pain, swollen glands , and rash. Signs and Symptoms Many folks, especially kids and teenagers, could expertise no signs or symptoms throughout a mild case of dengue fever. when symptoms do occur, they usually begin four to ten days once the person is bitten by AN infected dipteron (25). Signs and symptoms of dengue fever most typically include: Fever, up to 106 F (41 C) Headaches Muscle, bone and joint pain Pain behind your eyes You might also experience: Widespread rash Nausea and puking Minor trauma from your gums or nose Most people recover within per week or so. In some cases, however, symptoms worsen and may become grievous. Blood vessels typically become broken and leaky, and the number of clot-forming cells in your bloodstream falls (25). this will cause: Bleeding from the nose and mouth Severe abdominal pain Persistent puking Bleeding under the skin, which can appear as if bruising? Problems along with your lungs, liver and heart Clinical Course The characteristic symptoms of breakbone fever are sudden-onset fever, headache (typically situated behind the eyes), muscle and joint pains, and a rash (25). The alternative name for breakbone fever, break-bone fever, comes from the associated muscle and joint pains. The course of infection is split into 3 phases: febrile , critical, and recovery. The febrile part involves high fever, typically over forty Ãâà °C (104 Ãâà °F), and is associated with generalized pain and a headache; this sometimes lasts 2 to seven days. At this stage, a rash occurs in 50-80% of those with symptoms. It occurs within the initial or second day of symptoms as flushed skin, or later within the course of malady (days 4-7), as a measles-like rash. Some petechiae (small red spots that do not disappear when the skin is pressed, that are caused by broken capillaries) can appear at this point, as could some gentle trauma from the secretion membranes of the mouth and nose. The fever itself is classically biphasic in nature, breaking so returning for one or 2 days, though there is wide variation in however typically this pattern truly happens (26). Causes Transmission Dengue virus is primarily transmitted by Aides mosquitoes, particularly A. aegypti. These mosquitoes sometimes live between the latitudes of 35Ãâà ° North ANd 35Ãâà ° South below an elevation of 1,000 metres (3,300 ft). They bite primarily throughout the day. alternative genus Aedes species that transmit the malady embody A. albopictus, A. polynesiensis and A. scutellaris. Humans are the primary host of the virus, but it also circulates in anthropoid primates. AN infection is nonheritable via a single bite (27). infectious agent Replication Once inside the skin, breakbone fever virus binds to Langerhans cells . The virus enters the cells through binding between infectious agent proteins and membrane proteins on the Langerhans cell, specifically the C-type lectins known as DC-SIGN, mannose receptor and CLEC5A. DC-SIGN, a non-specific receptor for foreign material on nerve fibre cells, seems to be the main purpose of entry. The nerve fibre cell moves to the nearest node (28). Meanwhile, the virus ordination is replicated in membrane-bound vesicles on the cells endoplasmic reticulum, wherever the cells supermolecule synthesis equipment produces new infectious agent proteins, and the infectious agent RNA is traced (26). Severe malady It is not entirely clear why secondary infection with a unique strain of breakbone fever virus places folks at risk of breakbone fever hemorrhagic fever and breakbone fever shock syndrome. the most wide accepted hypothesis is that of antibody-dependent enhancement (ADE). the exact mechanism behind ade is unclear. it may be caused by poor binding of non-neutralizing antibodies and delivery into the incorrect compartment of white blood cells that have eaten the virus for destruction. there is a suspicion that ade is not the only mechanism underlying severe dengue-related complications, and various lines of analysis have implied a role for T cells and soluble factors like cytokines and the complement system (25). Diagnosis Diagnosing dengue fever is tough, as a result of its signs and symptoms is easily confused with those of alternative diseases like malaria, swamp fever and enteric fever. Your doctor can seemingly raise concerning your medical and travel history. make sure to explain international visits thoroughly, as well as the countries you visited and the dates, yet as any contact you will have had with mosquitoes. bound laboratory tests can observe proof of the breakbone fever viruses, but test results sometimes come too late to assist direct treatment selections . (25),(27) Classification The World Health Organizations 2009 classification divides dengue fever into 2 groups: uncomplicated and severe. The 1997 classification divided breakbone fever into undifferentiated fever, dengue fever, and breakbone fever hemorrhagic fever. breakbone fever hemorrhagic fever was divided additional into grades I-IV. Grade I is that the presence only of easy bruising or a positive bandage test in someone with fever, grade II is that the presence of spontaneous trauma into the skin et al, grade III is that the clinical proof of shock, and grade IV is shock so severe that pressure and pulse cannot be detected. Grades III and IV are noted as dengue shock syndrome (27). Prevention All control efforts ought to be directed against the mosquitoes. its important to take control measures to eliminate the mosquitoes and their breeding places. Efforts ought to be intense before the transmission season and through epidemics (25),(27). (1) stop dipteron bites: (a) breakbone fever Mosquitoes Bite throughout the Daytime defend Yourself from the Bite (b) Wear full-sleeve clothes and long dresses to cover the limbs. (c) Use repellents care ought to be taken in victimisation repellents on young kids and elders. (d) Use dipteron coils and electrical vapor mats throughout the daytime to stop breakbone fever. (e) Use dipteron nets to safeguard babies, old folks et al who could rest throughout the day. The effectiveness of such nets is improved by treating them with permethrin. Curtains also can be treated with insecticide and decorated at windows or doorways, to repel or kill mosquitoes. (f) Break the cycle of mosquito-human-mosquito infection. Mosquitoes become infected once they bite people that are sick with breakbone fever. dipteron nets and dipteron coils can effectively stop more mosquitoes from biting sick folks and help stop the spread of breakbone fever. (2) stop the multiplication of mosquitoes: Mosquitoes that spread breakbone fever live and breed in stagnant water in and around houses. (a) Drain out the water from desert/window air coolers (when not in use), tanks, barrels, drums, buckets, etc. (b) remove all objects containing water (e.g. plant saucers, etc.) from the house. (c) All stored water containers ought to be unbroken lined in any respect times. (d) Collect and destroy discarded containers within which water collects, Treatment There arent any specific treatments for dengue fever. Treatment depends on the symptoms, variable from oral rehydration therapy reception with shut follow-up, to hospital admission with administration of intravenous fluids and/or insertion. a decision for hospital admission is often based on the presence of the warning signs listed within the table on top of, especially in those with preexisting health conditions (27),(29). Conclusion Three immune parts interact to provide a confluence of symptoms that outline DHF/DSS. breakbone fever virus initially infects immature nerve fibre cells through the mediation of DC-SIGN. Infected nerve fibre cells contribute to pathological process through production of metalloproteases and cytokines (30). Downstream of nerve fibre cells T-cells become activated and generate the very cytokines concerned in tube-shaped structure leak and shock in addition to activating soul cells. protein enhancement is mediated by Fc receptors that are conspicuously on mature nerve fibre cells. infectious agent replication mediated by antibodies is increased 100-fold. in addition their effects on breakbone fever replication, antibodies to infectious agent epitopes cross react with cell a supermolecule that has the result of stimulating CD8 soul cells and production of cytokines and anaphylatoxins. Anaphylatoxins is generated directly through infectious agent proteins or through formation of AN antibo dy-complement advanced. Anaphylatoxins in turn can alter the reactivity of T-cells.

George Washington: Flaws and All Essay -- Informative Essay
There are many individuals in American History, whom we as Americans regard for their courage and audacity in shaping our nation. We learn in our history classes the great accomplishments of our founding fathers such as Thomas Jefferson, John Adams and Ben Franklin. One other great founding father and our First President, George Washington was one whom we learned much about. We learn in school that he is as a prime example of leadership, citizenship, and overall individual achievement for his many contributions to our nationââ¬â¢s earliest struggles. But although we are taught that George Washington was this man of great disposition, no man is without his flaws. Many scholars have sought to enlighten individuals to these cracks in the Nationââ¬â¢s perspective of our first president. The following composition will give an analysis of literature that shows George Washington was in consistent regarding his views on slavery. Although Washington is well-known for his many political accomplishments little is spoken about his views regarding slavery. George Washington was born on February 22, 1732. Despite losing his father at a juvenile age, 11, Lawrence his half-brother, 14 years older, quickly took over as a surrogate father figure to all of his younger siblings. Washingtonââ¬â¢s mother, Mary, became very protecting after the death of her husband (Georges father), Augustine. She kept George from enlisting in the British Navy contrary to the wishes of older brother, Lawrence. George lived with his older brother from the time he was about 15 and attended school in Virginia and never went to college. He was very good at mathematics which was quite suitable to his later occupation as a surveyor. In 1752, Lawrence also passed away his c... ...ntributions that they have made to our society. But it may be that we are disillusioned by what we are taught as children that we assume these people donââ¬â¢t have any faults. Maybe knowing these great men had faults helps to see them as more human. Minus the character flaw George Washington was still one of the framers of American society. Works Cited 1.

How to Solve Scarcity in the Economy Essay
SCARCITY: A pervasive condition of human existence that results because society has unlimited wants and needs, but limited resources used for their satisfaction. This fundamental condition is the common thread that binds all of the topics studied in economics. Scarcity is a perpetual problem facing society due to limited resources andunlimited wants and needs satisfied with these resources. Scarcity means that society does not have enough of everything (resources) for everyone (wants and needs). Two Components Consider the two sides of the scarcity problem. * Unlimited Wants and Needs: This is a basic characteristic of humanity which means that people are never totally satisfied with the quantity and variety of goods and services. It means that people never get enough, that there is always something else that they would want or need. * Limited Resources: This is a basic condition of nature which means that the quantities of available resources used for production are finite. It means that the economy has only so many resources that can be used AT ANY GIVEN TIME time to produce other goods and services. Humans live in a world of scarcity. This world of scarcity is what the study of economics is all about. That is why scarcity is usually subtitled: THE ECONOMIC PROBLEM. Scarcity does not preclude technological advances and other discoveries that ââ¬Å"lessenâ⬠the scarcity problem with better ways of satisfying wants and needs. In fact, scarcity actually predicts such things. People are motivated to work, go to school, invent products and discover new continents because they do not have all that they want. Why invent, discover, or explore if all wants and needs are satisfied? Increasing limited resources does not make them unlimited only less limited. Scarcity persists. Solutions? Scarcity has been a perpetual, pervasive problem of humanity. There is no reason to think the future will escape the wrath of scarcity either. But why not? Can humans ever hope to solve the scarcity problem? Technological advances in recent centuries have certainly done a great deal to lessen the scarcity problem. A notable share of the worldââ¬â¢s population residing in industrialized nations, while not free of scarcity, has achieved a relatively comfortable living standard. Given continued technological advances over the next few hundred years, perhaps society can solve the scarcity problem once and for all? It might happen. Who knows what the future might bring. But such is unlikely, even with technological advances. The reason for this economic pessimism rests with the two, and ONLY two, possible ways to eliminate scarcity. 1. Unlimited resources: Unfortunately, the planet Earth is finite. The solar system is finite. The galaxy is finite. In all likelihood, the universe is finite. None of this bodes well for achieving unlimited resources as a means of solving the scarcity problem. 2. Limited wants and needs: If every human being had finite wants and needs that could be satisfied with a finite amount of resources, then scarcity would cease to exist. But what sort of genetic engineering would be needed for this? Would humans still be human? 3. You allow the market price to rise to the point where demand=supply. The item will still be scarce (because it is not in unlimited supply), but everyone who is willing to pay the price will be satisfied. Alternatively, you can ration by authority. Someone with enough power to coerce people to do what they wonââ¬â¢t naturally do would simply choose who gets the scarce goods and who doesnââ¬â¢t. 4. Find economically viable alternatives/substitutes ââ¬â e.g. instead of petrol, try vegetable oil (it works, but I donââ¬â¢t think cars are made for them). 5. Alter supply ââ¬â e.g. instead of restricting imports, increase them. 6. Leverage ââ¬â instead of allowing one unit of electricity to produce one unit of good, you can make one unit of electricity produce 5 units of good. They call this economies/efficiency, but the principle can be applied to various areas outside of production. 7. Increase the price ââ¬â a side effect of the lack of supply, but you will probably be faced with lobbying groups. 8. Be prudent and prioritise use ââ¬â if itââ¬â¢s scarce, it shouldnââ¬â¢t be wasted. So cut back on non-necessities. 9. Innovate -R&D to find new ways to solve the problem. Alternatively, you can change a few things and make a massive difference. However, innovation is spontaneous and is often circumstantial. 10. Reduce demand ââ¬â change what the thing is used or alleviate the thing that it is used for. If the demand for the product is not there, scarcity is not so much a problem. Simpler said than done though. 11. Expansion of the productive capacity of an economy would help. However, it is likely scarcity will always exist as resources are limited but wants are infinite. So generally, it is how to allocate the resources most efficiently rather than how to solve scarcity, as scarcity canââ¬â¢t be solved. Resources have to be allocated at their optimum level, if this doesnââ¬â¢t occur it is known as market failure. The government can intervene in the form of taxation (placed on a good to discourage its consumption), subsidies (given to firms to encourage production of a good, which makes it cheaper therefore encouraging consumption), regulation (laws used to prevent consumption of a good) and pollution permits (allocated to firms allowing them to produce a certain amount of pollution, theyââ¬â¢re tradeable which encourages firms to be greener).

Southwestern Airlines
Southwest Airlines Co. (ââ¬Å"Southwestâ⬠) is a major U. S. airline that primarily provides short Haul high-frequency, point-to-point, and low-fare service. Southwest was incorporated in Texas and commenced operations on June 18, 1971 with three Boeing 737 aircraft Serving three Texas cities; Dallas, Houston, and San Antonio. Today Southwest operates nearly 400 Boeing 737 aircraft to 59 U. S. cities. Southwest has the lowest operating cost structure in the domestic airline industry and consistently offers the lowest and simplest Fares. Southwest also has one of the best overall customer service records. LUV is Southwestââ¬â¢s NYSE symbol, selected to represent the companyââ¬â¢s home at Dallas Love Field, as well as the theme of Southwestââ¬â¢s employee and customer relationships Within 30 years, Southwest Airlines has become the fifth largest major airline company in America. It currently operates 520 Boeing 737s throughout the United States. The mission of Southwest Airlines is dedication to the highest quality of customer service delivered with a sense of warmth, friendliness, individual pride, and company spirit. It primarily provides short haul, high-frequency, point-to-point, low-fare air transportation service in the United States. The company essentially functions as a ââ¬Å"point-to-pointâ⬠operation rather than a ââ¬Å"hub and spokeâ⬠service like its competitors. This provides for a unique competitive advantage, which has led this company to be a strong performer within the industry. The major success to their continued success is due to their low-cost model, as compared to their competitors, which allows Southwest airlines to differentiate itself from the competition and perpetuates its success and popularity among consumers. When we look at southwestern airlines competitive environment using porters five forces we find that the bargaining powers of Customers in the airlines industry have many options and are price sensitive. If driving is cheaper than flying southwest may lose customers. There are also over 100 carriers in the U. S. market therefore there are many options for customers. The bargaining power of suppliers: Southwest is at the mercy of the labor Unions and Gas suppliers. If these costs become too high then price raises will mandatory. The threat of new entrants: With so many major airlines going bankrupt there is a large supply of airplanes and personnel. This means that it is easier than ever to start up and airline and try and compete with Southwest. The threat of substitute products: Flying has very few substitutes in the U. S. market if you need to be somewhere in a hurry. However there are other forms of transportation including busses, trains, and cars. The intensity of competitive rivalry: There is intense industry competition. Every route is hotly contested with price wars and a grab for customers. Price margins are low, and airlines need to be able to trim costs any way they can. Southwestern airlines has got the following strengths; Southwest's commitment to customer service has led to an excellent track record. They held the unofficial Triple Crown in customer service for three consecutive years. The Triple Crown consists in being the best in on time performance, baggage handling, and customer satisfaction. This is an amazing feat considering no other airlines have held all three components for a single month. Southwest has a major advantage over other airlines because it operates a single type of plane, the Boeing 737. This means that all their pilots, facilities, and crews are trained on any plane that Southwest owns. Southwest also operates a fleet with an average age of 7 years. This means that they have less maintenance problems, and this leads to fewer delays, and higher customer service. Sensible expansion policy. Southwest has developed a very sensible strategy for expansion, paying particular attention not to strain the balance sheet. It has also achieved a national presence through flights to 59 airports in 58 cities. Southwest has been able to become a national airline by strategic expansion to airports where there is less competition. For example, it opened a major operation at Baltimore-Washington International and therefore avoided the presence of other major airlines at Reagan National and Dulles. The continued growth of the Company is testament to the strategic direction taken by management, particularly considering the difficult business environment. Southwest relies on direct ticket booking and does not heavily utilize travel agents this is a cost saver. They also do not have full food service on their flights, leading to a faster turnaround. Southwest also has a unique open seating system, with no assigned seats the planes load faster. Due to a change in passenger profile, business class and first class seats have suffered declining demand. Many companies have been forced to introduce low-cost fare options. Since southwest has been an industry leader and ââ¬Å"ahead of the curveâ⬠in providing low cost, standardized travel options, it has no need to change strategy, thus saving on restructuring costs. The Company also benefits from its long establishment in the low-cost airline market, allowing the Company to capitalize on significant customer awareness of the brand. Southwest has a highly efficient operation. The Company was first to introduce to the Airline industry the ten-minute turnaround (between arrival at the gate and departure). This has subsequently increased demand for short flight routes. Strong financials. Southwest has the strongest market capitalization and balance sheet of all rivals in the sector. A market capitalization of $14,022 million accounts for twice the market capitalization of the five largest rivals put together. In the current volatile market, it should allow southwest to overcome short-term downturns in demand more Successfully than the other main carriers. The continued ability of Southwest to produce positive results highlights it among rivals. 2003 saw quarter-over-quarter increases in income, representing 51 consecutive quarterly profit rises. Revenues for the full year 2003, which were $5,937 million, increased 7. 5% against 2002 revenues. Southwest does not fly into major hub airports in most cities, this leads to lower gate costs, less congestion, and quicker turnaround times. Southwest has been marketed as the low price leader, and their planes have been painted in funky colors. Southwest views its major competition as the automobile and not other airlines. Southwest airlines operate a single type of plane B737 in an all coach configuration. They do not offer meals, and do no transfer bags to other airlines leading to lower operating costs. The airline has won the Triple Crown and is setting the industry standard in customer service. Southwest has come under intense competition from United. They are not a full service airline and do not offer the amenities and services for international travelers. They also do not have a higher cost first class option on their planes. Marketing. Southwest is a low-cost carrier. They provide themselves on cost efficiencies, which enable them to offer good service at lower prices to the customer than their competitors. Their marketing strategy was to convey the message that what Southwest had to offer was of value. Southwest markets itself as the only major short-hop, low-fare, and point-to-point carrier in the U. S. airline industry. Their marketing style is known for being unconventional, unique, unpredictable, and attention-getting in order to create and reinforce the Companyââ¬â¢s maverick and fun-loving, combative image. They continually look for ways to make their distinctive image come alive and strike a spark in the minds of the consumer. Finance. In the year 2000, Southwest reported its 28th consecutive year of profitability as well as its ninth consecutive year of increased profits. In many years, Southwest was reporting profits while many other airline companies were reporting losses. Southwest is able to maintain and increase their profit margin by keeping costs low, being highly efficient, and creatively cutting costs. One of Southwestââ¬â¢s most important strategies is keeping its costs low and moving customers in above-average times. In an effort to move customers along quickly, Southwest tries to avoid congested airports. Southwest also encourages passengers to make reservations and ticket purchases through their website. By serving smaller airports near major metropolitan areas and in medium-sized cities, Southwest is able to produce better-than-average on-time performance, as well as reducing fuel costs of idle planes waiting for clearance to land. Serving smaller airports also lowers landing fees and terminal gate costs. Southwestââ¬â¢s operative principal is ââ¬Å"employees come first and customers come second. â⬠Southwest employees are ââ¬Å"hired for attitude and trained for skill. â⬠The Companyââ¬â¢s strategy is that it can train people to do the tasks and hold the skills that are required, but a personââ¬â¢s attitude is not something that can be changed. The hiring process involves an interviewing approach called ââ¬Å"Target Selection,â⬠which aims at matching peopleââ¬â¢s traits (or target dimensions) for performing a specific job successfully. New hires are trained at Southwest University for People. Managers trained in this program take leadership courses that emphasize a management style based on coaching and encouraging rather than supervising or enforcing rules. The Company has the lowest turnover rate in the industry, which may be partly due to the fact that 80% to 90% of supervisory positions are filled internally. However just like any organization, despite the fact that they have strengths, south west also has weaknesses which include: Little room for strategic development. The main weakness of the Company results from operating in a highly competitive market, one that is increasingly susceptible to a volatile political environment. The airline industry is highly competitive as to fares, frequent flier benefits, routes, and service. Some carriers competing with Southwest have larger fleets and a more established brand name. Many carry passengers from the major hubs in the U. S. , holding long-standing relationships with key airports. To enter these markets, the corporate strategy of Southwest will have to be adjusted. No established alliances. Certain major U. S. irlines have established marketing alliances with each other, including Northwest Airlines/Continental Airlines, American Airlines/Alaska Airlines and Continental Airlines/America West Airlines. In 2001, AMR Corp. , parent of American Airlines, completed its acquisition of the assets of Trans World Airlines. This puts enormous strain on the Company to maintain its position in the industry while running a smaller fleet. Fully valued share price. Despite Southwest holding the strongest financial position in the airline industry, the stock of the Company is considered fully valued, particularly in the short term. This will disconcert the investor searching for quick gains resulting in the potential loss of capital to its competitors. The strong financial position will apply pressure to the strategic direction of the Company, forcing the directors of Southwest to consciously pursue the same level of growth if they are to maintain investor confidence. South west airlines have got the following opportunities; Southwestââ¬â¢s greatest opportunity is directly related to its greatest strength: to continue to develop its low-cost position in the airline industry. Southwest must maintain an emphasis on low-cost flying, and brand association that has served it well so far. After September 11, customer numbers dwindled due to consumer fears over flying. One way the Company hopes to regain the trust of the public is through lower airfare. In 2002, no fare was more than $399. However, in August 2002, the company reduced fares even further, lowering last-minute fares while maintaining the full schedule of frequent flights in order to further stimulate travel. As of 2003 Southwest was offering fares as low as $39. The company must keep prices as low as possible in order to stimulate demands, and look to edistribute expenses through other areas. Continual streamlining and automation is necessary in order to both aid in cost-cutting and maintain the competitive advantage on which the company brand is based. Southwest has expanded ticket counters and security checkpoints and has increased its airport workforce. The boarding process has been streamlined through replacing the traditional plastic boarding card system with an automated one, and the carrier is in the process of rolling out new self check-in technology. This should result in a reduction of boarding times, and contrast sharply with those carriers that still have extensive queuing. Expand geographically. The market share Southwest holds has grown substantially, particularly since 9/11. Fifty percent of the core market is under control of Southwest and this is expanding. With the increase in the number of cities and networks to which it is linked, southwest could begin to target large city markets and with such a strong brand name, both marketing and PR costs will reduce. Furthermore, the timing appears perfect, if it wishes to capitalize on the pressure currently endured by many of the established carriers. Southwest could strengthen its position through an alliance. Many competitors have reduced share price due to poor financials. Southwest could exploit this through a merger or a favorable acquisition. This could provide an easier route into the major hubs and remove many of the challenges associated with entering new markets. A major threat comes from the unstable airline industry as the result of the 9/11 attacks. Immediately after the terrorist attacks, and in the face of falling demand for air service, most major carriers announced significant service reduction, grounded aircraft, and reduced employee levels. These events negatively impacted industry profits. Despite the absence of subsequent attacks, the political environment remains unstable, throwing into question the airlinesââ¬â¢ ability to make long-range strategic plans. Following 9/11, Southwest was able to offset losses through lower jet fuel prices and internal cost reduction initiatives. However, there can be no assurance that Southwest will be able to continue to offset future cost increases resulting from the changing commercial airline environment. Another threat derives from the Company being subject to varying degrees of competition from surface transportation in its short-haul markets, particularly the private automobile. The short-haul air services that compete with surface transportation regard price as a competitive factor for customers. Similarly, frequency and convenience of scheduling, facilities, transportation safety and security procedures, and customer service may be of equal or greater importance to many passengers. These can limit the number of customers who choose southwest. However, southwest airlines need to put up the following strategies; it needs to launch a new promotional campaign. They need to remind customers in the California market that they are the winner of the Triple Crown, and that low cost means high service and customer satisfaction when it comes to Southwest. With lower turnaround times, and fewer delayed flights southwest has great unique selling points. They just need to remind the public about how great an Airline they are. This can be done with more TV ads, and more sponsorship of major sporting events. Southwest also needs to continue to be southwest. They have a winning business model, and have made money every year of their existence. They cannot abandon what their core competencies are. They need to keep prices where they are, or even lower prices, and they advertise that fact to the public. Southwest airlines have been able to successfully implement its fuel hedging strategy to save on fuel expenses in a big way and have the largest hedging position among other carriers. In the second quarter of 2005, Southwestââ¬â¢s unit costs fell by 3. 5% despite a 25% increase in jet fuel costs. During Fiscal year 2003, southwest had much lower fuel expense (0. 12 per ASM) compared to the other airlines with the exception of JetBlue as illustrated in exhibit 1 below. In 2005, 85 per cent of the airlineââ¬â¢s fuel needs has been hedged at $26 per barrel. World oil prices in August 2005 reached $68 per barrel. In the second quarter of 2005 alone, Southwest achieved fuel savings of $196 million. The state of the industry also suggests t hat airlines that are hedged have a competitive advantage over the non-hedging airlines. Southwest announced in 2003 that it would add performance-enhancing Blended Winglets to its current and future fleet of Boeing 737-700ââ¬â¢s. The visually distinctive Winglets will improve performance by extending the airplaneââ¬â¢s range, saving fuel, lowering engine maintenance costs, and reducing takeoff noise. In an overall effort to improve customerââ¬â¢s in-flight experience, in-flight entertainment is something that Southwest is currently evaluating and which JetBlue has been very successful at already because of its introduction in its long-haul flights. In comparison, Southwest has 415 airplanes to consider and that represents an investment decision at a whole new dimension. Additionally, Southwest has to consider how things may fit into their environment. At this point, 60% of its service is still very short haul. Southwest needs to be mindful of the fact that a certain approach that has been successful for its competitor may not be necessarily work to its advantage. In summary, Southwest has long been regarded as a benchmark in its industry for operational excellence. Southwest Airlines is a fine example of a company that is committed to its core competencies ââ¬â efficient operations to drive its low cost structure, outstanding delivery of customer service and innovative HR management practices. We hope this paper provided a good insight into Southwest operations, as part of its overall strategy, to achieve success and gain competitive advantage.
