The Defence Mechanisms of the Lungs With Relation to Pulmonary Anatomy †Nursing Research Paper

The Defence Mechanisms of the Lungs With Relation to Pulmonary Anatomy – Nursing Research Paper Free Online Research Papers The Defence Mechanisms of the Lungs With Relation to Pulmonary Anatomy Nursing Research Paper The pathway taken by air during inhalation: During inhalation, air enters the nasal cavities via the nostrils, and also into the mouth during forced inhalation. It then passes through the nasopharynx, followed by the oropharynx. Air passes deeper into the thorax via the trachea, which then bifurcates to give the left and right primary bronchi. On entering the lungs, these become intrapulmonary bronchi, which immediately branch to give rise to the lobar (secondary) bronchi. Since the left lung is divided into two lobes, whereas the right lung is divided into three lobes, the right bronchus thus divides into three lobar bronchial branches, and the left into two bronchial branches, with each branch supplying one lobe. The left lung is further divided into eight bronchopulmonary segments, and the right lung, into ten such segments. Thus, in the right lung the lobar bronchi divide to give rise to ten segmental bronchi (tertiary bronchi), while left lobar bronchi give rise to eight segmental bronchi. The segments divide to give pulmonary lobules; each lobule is supplied by a bronchiole. Pulmonary acini are smaller units of structure th at make up the lobules. Each acinus derives it air supply from a terminal bronchiole. As of yet, no gaseous exchange has occurred. Thus, the passageways mentioned above are referred to as the conducting portion of the lung. Instead, the air is conditioned. This consists of warming, moistening and removing particulate matter. Only at the 17th division of the trachea does gaseous exchange commence. It first occurs at the respiratory bronchioles that arise from each terminal bronchiole, which will in turn give off alveoli. Thus, the smallest functional unit of the lung is the respiratory bronchiole unit, which consists of a respiratory bronchiole and the alveoli it supplies. Each alveolus is confluent with a respiratory bronchiole by means of an alveolar duct and an alveolar sac. Defence Mechanisms of the Nasal Cavities: The vestibule communicates anteriorly with the external environment. It contains hairs that filter out the largest-sized particulate matter before it is carried in the airstream to the rest of the cavity. The next segment of the cavity, the respiratory segment, is lined by ciliated, pseudostratified columnar epithelium. It possesses a smooth medial wall called the nasal septum; however, the lateral walls are thrown into folds by the presence of three shelf-like, bony projections called turbinates or conchae. These increase the surface area as well as cause turbulence in airflow to allow more effective conditioning of inspired air. The airstream is broken into eddies, and so matter suspended in the airstream is thrown out of the stream and adheres to the mucus-covered walls of the nasal cavity. It is the goblets cells dispersed between the ciliated cells that secrete mucin. Mucin later forms the mucus that traps debris. The cilia in turn provide a coordinated sweeping motion towards t he pharynx, where the mucus is swallowed. The lamina propria of the respiratory segment has a rich vascular network that includes a complex set of capillary loops. Furthermore, the turbinates increase the total surface area; this arrangement allows the air to be warmed rapidly, so as not to compromise core body temperature. These same vessels become engorged and leaky during allergic reactions or viral infections e.g. the common cold. The lamina propria then becomes distended with fluid, resulting in marked swelling of the mucous membrane with a consequent restriction of the air passage. This makes breathing difficult. Part of the dome of each nasal cavity, and to a lesser extent, the contiguous lateral and medial nasal walls, form the olfactory segment that contain olfactory mucosa. The main constituent of this layer is the olfactory cell. It is a bipolar ciliated neuron that possesses receptors from which the sensation of smell is derived. Over the millennia, man has evolved to dislike odours resembling that of rotting flesh, which possesses micro-organisms and viruses that are harmful not only to the pulmonary system, but to the entire body as well. Defence Mechanisms of the Pharynx: The sub-epithelial tissue of the posterior wall of the nasopharynx possesses diffuse lymphatic tissue. Furthermore, lymphatic nodules are concentrated in the adenoids (pharyngeal tonsils) in the roof of the pharynx, and tonsils (palatine tonsils) on either side of the pharynx. These structures are strategically located to allow the nodule cells to intercept and react with foreign antigens and then travel to regional lymph nodes, where they undergo proliferation and differentiation. Progeny of theses cells return to the lamina propria as effector B and T lymphocytes, as plasma cells, and as memory cells. Respiratory tract nodules also have large numbers of eosinophils as compared to other nodules. This is most visible in times of chronic tonsil inflammation and hypersensitivity (allergic) reactions. Defence Mechanisms of the remainder of the conduction pathway: The larynx shows numerous adaptations to air conduction. The luminal surface of the vocal cords of the larynx is covered with squamous epithelium. This serves to protect the inner layer of the larynx, the mucosa, from abrasion by the rapidly moving airstream. The rest of the larynx is covered by the ciliated epithelium characteristic of the respiratory system, as are the trachea, bronchi, and larger bronchioles. However, the main adaptation at this level is the presence of an epiglottis. The epiglottis is the valve-like flap of cartilage lying behind the tongue and in front of the entrance to the larynx. At rest, the epiglottis is upright and allows air to pass through the larynx and into the rest of the respiratory system. During swallowing, it folds back to cover the entrance to the larynx, preventing food and drink from entering the windpipe. If both the oesophagus and the larynx were open when a person swallowed, air could enter the stomach and food could enter the lungs. When fo od enters the larynx, the airways are blocked, and we start to choke. The epiglottis works with the larynx to act as a lid every time we swallow. The larynx draws upward and forward to close the windpipe. This keeps solid food and liquid out of the respiratory tract. At the end of each swallow, the epiglottis moves up again, the larynx returns to rest, and the flow of air into the windpipe continues. Cough, Sneeze and Gag Reflexes: The function of both the cough reflex and the sneeze reflex is to dislodge foreign matter or irritating material from respiratory passages. The bronchi and the trachea contain sensory receptors that are sensitive to foreign particles and irritating substances. It is also thought that the upper gastrointestinal tract possesses cough receptors. The cough reflex is initiated with the sensory receptors detect these substances and initiate action potentials that pass along the afferent vagus nerves to the medulla oblongata, where a poorly defined cough centre is located. The movements resulting in a cough occur as follows: about 2.5 litres of air are inspired. The epiglottis closes, and the vestibular folds and vocal cords close tightly to trap the inspired air in the lung as a result of stimulation by efferent neurons. The abdominal muscles contract to force the abdominal contents up against the diaphragm, and the muscles of expiration contract forcefully. As a consequence, the immense p ressures are developed in the lungs that may reach up to 100 mm Hg. The vestibular folds, the vocal cords, and the epiglottis then open suddenly, causing air to rush out of the lungs at a high velocity, carrying foreign particles with it. The sneeze reflex is similar to the cough reflex, but it differs in several ways. The source of irritation that initiates the sneeze reflex is in the nasal passages instead of in the trachea and bronchi, and the action potentials are conducted along the afferent trigeminal nerves to a different centre in the medulla. During the sneeze reflex the uvula and the soft palate are depressed so the air is directed primarily through the nasal passages, although a considerable amount passes through the oral cavity. The rapidly flowing air dislodges particulate matter from the nasal passages and propels it a considerable distance from the nose. The gag reflex is important for removing foreign bodies from the pharynx and oral cavity. The normal gag reflex is a mass contraction of both sides of the posterior oral and pharyngeal musculature. The contractions of the pharyngeal musculature on the same side as the site of stimulus is called the direct response, while the contractions of the other side are called the consensual response. Defence mechanisms of the Alveoli: The alveoli possess numerous macrophages that pass with ease between alveolar cells. They are unusual in that they function in both the connective tissue of the septum and in the air spaces of the alveoli. In the air spaces, they are referred to as dust cells, because they scavenge the surface to remove inhaled particulate matter. They also phagocytise erythrocytes that may enter the alveoli in heart failure. Some engorged macrophages pass up the bronchial tree in the mucus and are disposed of by swallowing or expectoration when they reach the pharynx. Other macrophages return to or remain in the septal connective tissue, where, filled with accumulated phagocytised material, they may stay for much of an individual’s life. Finally, they phagocytose infectious microbes such as tubercle bacilli. These bacilli are not digested by the macrophage, so other infections or conditions that damage alveolar macrophages can cause the release of tubercle bacilli and recurrent tuberculosis. Diseases of the pulmonary system: Smoking greatly reduces the effectiveness of pulmonary defence. First, smoking reduces coughing in response to smoke, which is why they can smoke without continuously coughing, and second, smoking effects the rate at which the lungs cilia beat. In acute (short term) cases of exposure to smoke, cilia are paralysed temporarily. In the long run, the cilia will be destroyed permenantly. Furthermore, smoke contains irritants, namely tar, that stimuklates mucus secretion in the larger bronchioles by goblet cells. The resultant stagnation produced at that point in long-term smokers means that the lungs are very susceptible to recurrent infection, particularly pneumonia. To eliminate the mucus, such people develop smoker’s cough, which is so violent it can tear parts of the respiratory vessels and burst numerous alveoli. Blod will often be present in the sputum, and the damaged tissue is replaced by scar tissue. The resulting emphysema is further complicated by the fact that alveolar macrophages secrete proteases and elastases that digest the elastin surrounding alveolar sacs and allow these cells to reach rapidlt to the sites of infection. The reduction in compiance is dueto the fact that alveolar air cannot be replaced as efficiently as before without the recoil provided by elastic tissue. Asthma is an inflammatory disease of the airways characterised by wheezing, swelling, excess fluid build-up and mucus plug formation. The major step in the inflammatory process is exposure to these allergens or triggers. In the first exposure to the harmless allergen, specific B-lymphocytes recognises an antigen of the allergen, and so it divides rapidly by clonal expansion to produce plasma cells and memory cells. The plasma cells, in turn, produce IgE immunoglobulins. Mast cells and basophils in the lungs have special IgE receptor sites on their surfaces to which the IgE molecules attach. These cells are now sensitised to that allergen. On the next exposure to the allergen, the attached IgE antibody comes in contact with the allergen it was designed specifically to recognize, and, and the mast cells begin to degranulate. The released chemicals attract memory cells. Secretion of more IgE by the proliferating memory cells stimulates the release of several inflammatory-response mediat ors. These chemicals include histamine, leukotrienes, and prostaglandins. They are what cause the symptoms of an allergic reaction. They can stimulate the production of excess amounts of mucus and fluid in the airway, which plug the airway, and also bind to specific receptors on the smooth muscles of the bronchioles, causing severe bronchoconstriction.

Concepts and principles of emergency management Essay

Concepts and principles of emergency management - Essay Example In Australia, latest statistics on car accidents seem to indicate that road accidents are increasing in frequency; road deaths associated to such car accidents are also increasing. In 2005, Australia already ranked 7th out of 15 developed nations for road deaths per 100 million vehicle kilometres travelled (Fallah, 2007). Emergencies -- are â€Å"incidents that threaten public safety, health and welfare (Department of Environmental Management, n.d, p. 1). Emergencies may also vary in size, location, causes, and effects; but regardless of differences in such elements, they all register with various environmental effects. They are also defined by the Emergency Management Institute (n.d) as unexpected incidents or events which endanger lives or property, consequently requiring urgent and routine responses through community resources and procedures. Examples include: road-blocking landslides, long power outages, forest fires, outbreaks of diseases, and heat waves (Central Coast Center Independent Living, n.d). There were two slides in Australia from 1939 to 2007; 28 were killed and about 101 individuals were affected (CRED, 2007). There were 28 wild fires from 1939 to 2007 and this caused the death of about 300 individuals and damages up to 1.2 million US dollars (CRED, 2007). There was one epidemic fro m 1939 to 2007. No deaths and no damages were reported but 6 people were affected (CRED, 2007). Disasters are defined by Emergency Management Australia (2004, p. ix) as â€Å"a condition or situation of significant destruction, disruption and/or distress to a community†. The United Nations (1992) define a disaster as â€Å"a serious disruption of the functioning of society, causing widespread human, material, or environmental losses which exceed the ability of affected society to cope using its own resources† (UN Glossary, 1992).

Communiction Theories Essay Example | Topics and Well Written Essays - 250 words - 4

Communiction Theories - Essay Example For example, the phrase â€Å"Where are you going†, without the question mark will be read flatly whereas, when written in the form, â€Å"Where are you going?†; there is an indication that the speaker should have a falling pitch. Moreover, the importance of punctuation marks are seen in the meanings relayed in the sentences. For instance, â€Å"They are Grants sisters† and â€Å"They are Grant’s sisters† imply different meanings where the former presents two probable corrections. First, it may be considered that the writer missed a word and can be corrected as â€Å"They are the Grants sisters† meaning, they are the sisters from the Grants family. Secondly, it could be edited to form the second sentence with the apostrophe, distinctly stating that they are the sisters of Grant. It is vital not only to place the punctuation marks on the right places but also to use the correct punctuation mark because they can change the tone of a sentence which consequently will change the meaning of the sentence. â€Å"You are good.†, is a statement. â€Å"You are good!†, indicates an excited feeling towards the person being appreciated. â€Å"You are good?†, poses a challeng ing tone to the person being referred to regarding goodness. These few examples show how punctuation marks affect communication so much that students and professionals alike are drawn to the study of

How do Bad Debts Affect the Profits of Bahrain Duty Free Essay

How do Bad Debts Affect the Profits of Bahrain Duty Free - Essay Example The company is one of the greatest retail companies situated in the airport of Bahrain and it is worth for every individual to come and spend some time in this award winning duty free outlet. The company has been acclaimed internationally among the airport retail industry backed with an array of awards for the purpose of executing outstanding performance within the retail duty free industry. The company being located centrally between gates 14 and 15 on the departure concourse of the airport the duty free shopping in Bahrain duty free provides an extravagant shopping experience to the customers with international brands, prestigious brands and world class retail section highly known for its diverse types of products and also deemed as one of the finest airport facilities shopping all over the globe (Shopping and Eating, Bahrain International Airport). But despite of this reputed stature the company faces huge losses and one of the major reasons can be attributed to the bad debts affe cting the profit margins of the Bahrain Duty Free Complex. I have concentrated on secondary resources for providing relevant answers to the question. However the resources on the bad debt affecting the profitability of the company is limited although I have made a rigorous search for answering the questions by taking proxies of bad debts as outstanding loans, non performing loans, losses, fall in accounts receivables and several other key words for relating the same and answering the question. Procedure I have decided to write the topic on the basis of different secondary sources which are given in the following tabular representation. Annual Report 2011, Bahrain Duty Free Annual Report 2010, Bahrain Duty Free Article- UAE’s non-performing loans to peak in 2012 Article- UAE’s non-performing loans to peak in 2012 Book- Internal Revenue Service Tax Information Publications, The Service, Volumes 1-2; Volume 20001 Loopholes in national legal system Now I will move into the discussion of the paper. A business bad debt is a form of loss which generates from the worthlessness of a debt primarily from two main areas. Firstly it comes from creation or acquiring within the trade or business or secondly is closely related with the trade or business when it becomes partly or totally worthless. The bad debt of a corporation is always business bad debts. A debt is related closely to the trade or business if the primary motive for the purpose of incurring debt is a business reason (Taxpayer Information Publications, 342). Bahrain Duty Free (Duty Free) played dominantly in the market within the time span of 1991 to around 2000. Then the company encountered a massive drop in the year 2001 with a drop of around 20.9% in the net earnings post 9/11 attacks. Sales declined with an increase in the operating expenses. The company encountered a massive decline of around 8.1% in the net profit in comparison with the previous years. The second half of the year has also no t been different for the Bahrain Duty Free. With the outbreak of 9/11 attacks the global aviation industry became crumbled and the Middle East have been no exception. With the declining number of passengers as well as jeopardized global economic conditions which has been exacerbated by the attacks of 9/11 pushed heavily on the line of growth of the company. There has also been a drop of 20.9% drop in the net earnin

Impact of Internationalisation of Business Markets

Impact of Internationalisation of Business Markets This report aims to analyse and discuss the internationalisation of business and global marketing issues. It also analyses the influence of global marketing environment on the marketing activities of the firm. In order to prepare this report, there has been a use of various Academic textbooks and journals. Over the past thirty years, internationalisation of the firm has been the most frequently researched topics in international marketing (Fletcher 2001). It has been used to describe the outward movement or increasing involvement in a firms or larger groupings international operations (Fillis 2000). In general, Internationalisation refers to the increasing importance of international trades, international treaties, international relations, alliances, etc. Firms undertake international operations due to various reasons (Lam and White 1999). Some internationalise due to the fact that their competitors or customers have been globalised (Ohmae, 1990), whereas others are pushed by the idea of multinationalism as a symbol of success and progress (Gerlinger et al. 1989). The firms use a stepwise approach along with an organisational continuum, in order to develop the international operations. The Uppsala School views internationalisation as having four stages while it has also been modelled with five and six. Although the number of incremental steps may differ, there is general agreement that with each subsequent step comes increasing involvement in international operations. However, due to increasing globalisation, chaotic market conditions and technology effects, it is believed that such stepwise advancement is not generally exhibited in SMEs and that alternative modelling of microenterprise behaviour is needed in order to account for emerging modes of behaviour (Fillis 2000). Definition of Internationalisation: There are many possible definitions of Internationalisation, some referring to the whole economy of the home or internationalising, country, some referring to specific sectors of the economy, and some referring to MNEs themselves (Kumar, N 1998). Calof and Beamish (1995: 116) denotes Internationalisation as the process of adapting firms operations (strategy, structure, resources, etc) to international environments. Whereas, Welch and Luostarinen (1988), Rao and Naidu (1992), Easton and Li (1993) and Johanson and Vahlne (1993) has defined internationalisation as a process by which firms increase their involvement in international business activities. From the above-proposed definitions, it can be concluded that Internationalisation is a process in which the firm gradually increases its international involvement. Complexity and challenges in Internationalisation: Internationalisation is a process which is very complex and challenging by nature. There have been various factors which have made internationalisation as a complex process. The most important factors are uncertainty in formats, formula and markets, the high degree of operational flexibility required and there need to be the high rate of formula innovation in order to get a success in internationalisation (Dawson, J. 2003). Uncertainty in Formats, Formula and Markets: As being an international market for the internationalising firm, it is very uncertain. The firm faces huge competition from the local markets. These all factors make internationalising for the firm very challenging. High degree of operational flexibility required: In order to perform a successful internationalisation process, there needs to be a high degree of operational flexibility, which will give an advantage to the internationalising firm over the local firms. Need of high rate of formula innovation: In order to gain an advantage over the local firms, the internationalising firm has to be very active in terms of innovation. As the competition will be high for the internationalising firm there needs to be a rapid innovation of the formula. Uppsala Internationalization Model: The Uppsala Internationalization Model was originally developed by Johanson and Vahlne (1977, 1990). This model, also known as the incremental theory of internationalisation, shows that enterprises gradually increase their international involvement according to the development of their knowledge about foreign markets and operations. Camuffo et al. (2007) enhanced this model by adding technological knowledge and customer-supplier interaction as important determinants of the process, stating that cross-border expansion into a neighbouring country might shorten the time required to accumulate knowledge and to control the facility in the target country (Reiner, G. 2008). The Uppsala model has described the internationalisation of a firm as a process of experiential learning and incremental commitments which lead to an evolutionary development in a foreign market. Johanson and Vahlne formulated this approach in 1977, referring to empirical observations on Swedish manufacturing firms from their studies at the international business department of Uppsala University. One of the basic assumptions of the model is that the lack of knowledge is an important obstacle to the development of international operations (Johanson Vahlne, 1977: 23). Hence, the Uppsala model has dealt fundamentally with knowledge acquisition and learning. It has been observed that the absence of market-specific knowledge has forced the many manufacturing firms to develop their international operations in small steps, undertaking incremental commitment decisions and moving at the beginning to psychically close countries in order to reduce the market uncertainty (Johanson Vahlne, 1977 : 24). Uppsala model is based on four core concepts: market commitment, market knowledge, current activities and commitment decisions. These four concepts are then divided into state aspects and change aspects. The two state aspects are market commitment, which is the resources committed to foreign markets, and market knowledge, which is the knowledge about foreign markets and operations possessed by the firm at a given time. The two change aspects are current activities and commitment decisions. The latter are the decisions to commit resources to foreign operations (Johanson Vahlne, 1990). Drawback of Uppsala Internationalisation model: The Uppsala model has been criticised for being partial and deterministic (Hollensen, S. 2007).The first criticism is based on the fact that Johanson and Vahlne 1977 rely on only one construct- experiential knowledge as one of several constructs, including the decision making process of the firms management. On the other hand, the internationalisation process model does deal with how other factors are handled in the process (Blomstermo, A. 2003). The criticism that the model is deterministic has to do with the incremental development of experiential knowledge and its manifestation in the visible stage model. Researchers provide empirical evidence that shows that firms do not always start with occasional exports and end up with a production company abroad (Newbould, Buckley and Thurwel 1978).It has also been argued that the model does not take into account interdependencies between different country markets (Johanson and Mattson, 1986) Advantages of Uppsala Internationalisation model: After analysing the Uppsala Internationalisation model it was found that there have been very few advantages. The only advantage associated with this model is that it explains the internationalisation process. In comparison to all the other models of internationalisation this has been highly criticised (Madsen, K. 1991). Macro-environment Forces: Whether its an international banking organisation, a university or a manufacturer, no organisation exists within a vacuum. It is very likely competitors, to be subject to international, national and local control, obliged to comply with national or European pollution fluctuations in the fortunes of the global economy (Brooks, I. 2004). Factors that influence a companys or products development but that are outside of the companys control. For example, the macro environment could include competitors, changes in interest rates, changes in cultural tastes, or government regulations etc (Hill, C. 2009). Macro- environmental forces influencing Internationalisation process: The various outside influence on a firms decision to go international are as follows: Export Agents Governments Chamber of commerce Banks etc. Unsolicited international orders are one major factors influence the firm to begin exporting. In United States, such orders have been found to account for more than half of all cases of export initiation by small and medium-sized firms. Another major influencing agent may actually be a competitor. Just as firms respond to competitive pressures from other companies, statements by executives from other competing firms may serve as change agents (Czinkota, M. 2007). Export Agents: Export agents as well as export management firms generally qualify as experts in global marketing. They are already dealing internationally with other exportable products, have overseas contacts and are set up to handle other exportable products, have overseas contacts and are set up to handle other exportable products. Many of these trade intermediaries approach prospective exporters directly if they think that their product have potential markets overseas (Hollensen, S. 2007). Governments: In nearly all countries governments try to stimulate international business through providing global marketing expertise (export assistance programmes). For example, government stimulation measures can have a positive influence not only in terms of any direct financial effects that they may have, but also in relation to the provision of information (Welfens, P. 2001). Chambers of commerce: Chambers of commerce and similar export production organizations are interested in stimulating international business, both exports and imports. These organizations seek to motivate individual companies to get involved in global marketing and provide incentives for them to do so on. These incentives include putting the prospective exporter or importer in touch with overseas business, providing overseas market information, and referring the prospective exporter or importer to financial institutions capable of financing global marketing activity (Hollensen, S. 2007).. Banks: Banks and other financial institutions are often instrumental in getting companies to internationalize. They alert their domestic clients to international opportunities and help them to capitalize on these opportunities. Of course, they look forward to their services being used more extensively as domestic clients expand internationally (Czinkota, M. 2007). Common Customer needs: In general, standardization is less likely with services that with goods. Within services, the potential for standardization is greater the less the provider is involved in the delivery because this increases the extent to which customer needs are likely to have more features in common. Scale Economies: These are driven by the opportunity to spread fixed costs. With services, such economies are more likely to come from standardised processes than from a physical concentration of activities (Blythe, J. 2005). Competition Drivers: These often occur because the service provider finds it necessary to go international in order to protest its position in the domestic market, especially if costs can be lowered. If the service providers do not take this step, then there is an increased risk that firms in the international market may use that market as a base from which to internationalise their operations (Toyne, B. 1989). Information Technology drivers: The ability to centralise information hubs on a global basis is a motive because it strengthens the firms competitive position. For example: Rupert Murdochs involvement in satellite TV in order to monopolise sports coverage (Brown, L. 2004). Apart from the above-mentioned drivers, there are some more drivers of internationalisation such as Revolution in information and communications systems, globalisation of financial markets and also improvements in business travel (Blythe, J. 2005). Conclusion: From the above discussion and findings, it can be concluded that Internationalisation is a process in which the firm gradually increases its international involvement. It has been also found that the internationalisation is very complex by nature. Various models of internationalisation have been proposed till date, out of which the most famous model is Uppsala approach model of internationalisation. However, it was found that there have been various drawbacks in this model such as, being partial and deterministic, not taken into account interdependencies between different country markets etc. From the discussion of the influence of various macro environmental forces on internationalisation, it can be concluded that there is an increasing number of influence on the firms to go for industrialisation.

A womans view Essay -- essays papers

A womans view A Women’s View There are a lot of specific cultural values that have been taught to women by society since birth. The three essays, â€Å"I Want a Wife† by Judy Syfers, â€Å"How the Superwoman Myth Puts Women Down† by Sylvia Rabiner, and â€Å"An Open Window On My Private World† by Jane Elizabeth Lemke are all written by women who share their experiences with us. The three essays explore the value of self, power, control, and life. First of all, in the essay, â€Å"I Want a Wife†, Judy Syfers exposes the meaning of â€Å"wife† presently in our society. Her argument is based on the premise that all wives are completely devoted to their husbands and are willing to tend to all their needs and satisfy them completely while working, being a good mother, and remaining gorgeous. Syfers reveals her definition of a wife in a very sarcastic and frustrated manner. Also, the style of the whole paper is very ironic. Almost as if she is screaming, she concludes her essay with, â€Å"My God, who wouldn’t want a wife?†(pg.648, 11). The cultural values portrayed in this essay are the value of control and the value of wanting to be loved. The value of control is portrayed in our society by the husband having the control and power over his wife. Because o f that control, t...
