Sustainable urban develpment - Thesis Example The invisible impacts are more deep rooted, though they are difficult to see and assess. These invisible impacts include changes in the quality of life, changing social structures and genetic changes. There are also several possible impacts of urban development, namely, increase in employment opportunities, cost-effective and efficient supply of basic amenities like water, electricity, gas etc., availability of medical and educational facilities, and promotion of safe and environmental friendly public transport system. The implementation sites are therefore required to be sustainable or assessed so as to evaluate the associated costs and benefits to the region and to the life of the people. For this, various environmental impact assessment is carried out. There are several methods for carrying out the environmental impact assessment like the checklist method, the matrix method, the network method, the overlay method and the battelle method. While all the methods have their applicability, Battelle method is found to be more holistic as it takes into account a large number of parameters related to the physical environment and human habitats and also assigns weights based on relative importance of the factors at the given site. The current study uses the Battelle method to evaluate a large implementation site at Hayeel. This implementation site, which is a mixed-use project, covers an area of 3,000,000 meter squares. The results of the Environmental Impact analysis show a negative EIU (Environmental Impact Unit) of -503.9 which means the development will affect the sustainability of the site. The research concludes with making several recommendations that can help in mitigating the detrimental impacts of the implementation site. (I suggest you add some more specific recommendations based on your actual

Early Graphic Design - Essay Example Social Factors – the rise of the Industrial Revolution with the invention of the steam engine in many ways brought about disruptive changes to society, in which the previous agricultural or feudal system gave way to industrialisation due to a new economic system of capitalism. It gave rise to urban slums where family members were separated, an exploitation of labour and the rise of a new wealthy class of capitalists, in addition to landed aristocracy and royalty. Economic Factors – capitalism is enhanced by the new economic system of industrialisation, in which goods were mass produced for consumption, unlike the previous production system of individually-crafted products made by skilled artisans and their guilds. The sheer number of new products on the market required a new way of marketing these products to people and one way to distinguish one product from another is the use of graphic design to entice buyers.The mass production of goods caused the birth of graphic d esign as a form of advertisement, but this kind of new art was considered a poor imitation of the earlier Gothic style of designs. The Gothic or medieval style was more detailed and thought to be real works of art borne out of the dedicated and loving work of artisans who produce these art works for only few people but not for the mass market. The Gothic style, according to Pugin, represented religion and it was also considered to be English, in contrast to the classical style which he thought as pagan and worldly.

Idiopathic Pulmonary Fibrosis: An Overview

Idiopathic Pulmonary Fibrosis: An Overview Jennifer Beardsley Abstract Idiopathic pulmonary fibrosis (IPF) is a devastating interstitial lung disease that has no cure. The term fibrosis refers to scarring, in IPF particularly the scarring of the lungs. The scarring causes irreversible destruction and progressive decline of the lungs. When the tissue thickens, the lungs cannot properly exchange oxygen. The term idiopathic, in medicine, means that the origin of the disease is unknown. The exact cause of IPF is unknown, however, certain risk factors such as smoking, exposure to inhaled toxins such as asbestos, lung injury, viral, and bacterial infections, acid reflux and genetics associated with the disease. IPF mainly affects people ages 50 and up. â€Å"Many people live only about 3 to 5 years after diagnosis. The most common cause of death related to IPF is respiratory failure† (â€Å"What Is Idiopathic Pulmonary Fibrosis? NHLBI, NIH,† n.d.). â€Å"40,000 people die each year to IPF, the same as to breast cancer† (â€Å"Facts Abou t Idiopathic Pulmonary Fibrosis | Coalition For Pulmonary FibrosisCoalition For Pulmonary Fibrosis,† n.d.), yet IPF is still an unknown disease to many people. This paper will discuss the risk factors, disease process, complications, management, and new drug therapy clinical trials. Idiopathic Pulmonary Fibrosis: An Overview Etiology Idiopathic Pulmonary Fibrosis first started to become recognizable around the late 1800’s (Noble Homer, 2005). While currently the exact cause is unknown, there have been several risk factors that are recognized to contribute to the disease. As mentioned above, smoking, exposure to inhaled toxins such as asbestos, lung injury, viral and bacterial infections, acid reflux and genetics are associated with the disease (Noble Homer, 2005). Smoking accelerates the loss of lung function by destroying the cilia inhibiting the lungs natural ability to clean and repair itself (Oh, Murray, Molfino, 2012). Smoking also damages alveoli, causing poor gas exchange. The chemicals in cigarettes contribute to lung decline and disease and coat the lungs with tar and toxins (Oh et al., 2012). Inhaled substance and toxins such as asbestos are hypothesized to increase IPF probability (Meltzer Noble, 2008). When toxins invade the lungs, they interfere with the alveoli gas exchange process (Meltzer Noble, 2008). Lung injury can cause permanent damage. Acute lung injury has been hypothesized to accelerate an underlying progression of IPF. When cells of the lungs are damaged, it can be irreversible (Kottmann, Hogan, Phipps, Sime, 2009). Viral and bacterial infections cause a build of mucus in the lungs. When the alveoli get clogged they cannot properly exchange oxygen and carbon dioxide. Each infection acquired can cause more damage and can lead to permanent damage. When the lungs lose their ability to exchange gas, oxygen is inhibited from reaching the body’s vital organs (Kottmann et al., 2009). GER, commonly known as acid reflux, occurs when acid is aspired into the esophagus. â€Å"Researchers have found that 9 out of 10 people who have IPF also have gastroesophageal reflux disease† (â€Å"What Causes Idiopathic Pulmonary Fibrosis? NHLBI, NIH,† n.d.) Recent research has found that genetics may play an important role in the risk factor of developing IPF. â€Å"Over the past decade, one aspect that has held great promise in helping the medical community to better define the pathogenesis of IPF is the recognition that genetic factors may play a role in this disease† (Lawson, Loyd, Degryse, 2011). Pathophysiology The cause of IPF is unknown. Despite considerable advancement in understanding the progression of IPF, the knowledge of the beginning stages of IPF re still inadequately understood (Noble Homer, 2005). Originally, in the 1970’s, it was thought that inflammation of the alveoli was the cause (Noble Homer, 2005). It was believed that untreated inflammation leads to the scarring of the lungs. Anti-inflammatory and corticosteroids were widely used to treat the inflammation. However, those therapies have proven ineffective, making it evident that inflammation was not the cause (Dempsey, Kerr, Gomersall, Remmen, Currie, 2006). The second theory that came about in the 1980’s suggesting growth termed â€Å"alveolar macrophage-derived growth factor† (Noble Homer, 2005). Known as the ‘growth factor hypothesis’, it is believed that abnormal healing of trauma within the lungs exaggerates the response and growth of profibrogenic causing the scarring of IPF (Noble Homer, 2005). This theory still proves to be a highly important discovery in the pathophysiology of IPF (Dempsey et al., 2006). A third theory also came out of the 1980’s, known as the epithelial-mesenchymal hypothesis, suggests that tissue death of alveolar epithelial cells can lead to alveolar collapse (Noble Homer, 2005). The epithelial- mesenchymal cell conversion can alter and change motility and the ability to heal. â€Å"Imbalance of the normal homeostatic microenvironment might be, per se, a cause of fibroblast proliferation and myofibroblast differentiation leading to fibrosis† (Prunotto et al., 2012). Clinical Manifestation According to the Coalition for Pulmonary Fibrosis, â€Å"Idiopathic pulmonary fibrosis (IPF) is a progressive and generally fatal disease characterized by scarring of the lungs that thickens the lining of the lungs, causing an irreversible loss of the tissue’s ability to transport oxygen. IPF ultimately robs a patient of the ability to breathe†(â€Å"Facts About Idiopathic Pulmonary Fibrosis | Coalition For Pulmonary Fibrosis,† n.d.). IPF usually occurs in older adults in their 50’s or 60’s, and tends to occur more in men than in women (Lawson, Loyd, Degryse, 2011). According to the Coalition For Pulmonary Fibrosis, IPF affects about 128,100 people in the United States, with 48,000 new cases diagnosed annually (â€Å"Facts About Idiopathic Pulmonary Fibrosis | Coalition For Pulmonary Fibrosis,† n.d.). â€Å"IPF has been reported to occur throughout the world in many different racial and ethnic groups. Studies in the United States have sugge sted that Caucasians are more likely to be diagnosed with IPF and have higher mortality rates from IPF than African Americans. It is unclear if these findings are due to real differences in racial characteristics or to an under-diagnosis of this condition in minority populations† (Siegel, 2011). IPF symptoms develop over time and usually are not diagnosed until serious damage has already been done to the lungs (â€Å"What Are the Signs and Symptoms of Idiopathic Pulmonary Fibrosis? NHLBI, NIH,† n.d.). Patients are often misdiagnosed with diseases that present similar symptoms such as Chronic Obstructive Pulmonary Disorder (â€Å"Facts About Idiopathic Pulmonary Fibrosis | Coalition For Pulmonary Fibrosis,† n.d.). Idiopathic pulmonary fibrosis usually present gradually with a nonproductive cough and dyspnea. (Hyzy, Huang, Myers, Flaherty, Martinez, 2007). The main symptom patients complain of being shortness of breath (Noble Homer, 2005). Other common symptoms include: â€Å"dry, hacking cough; rapid, shallow breathing; gradual, unintended weight loss; Fatigue (tiredness) or malaise (a general feeling of being unwell); clubbing, which is the widening and rounding of the tips of the fingers and toes† (â€Å"What Are the Signs and Symptoms of Idiopathic Pulmonary Fibrosis? NHLBI, NIH,† n.d.). The gold standard for diagnosis of patients with IPF is a surgical lung biopsy (SLB), however critical risk for these patients usually prevent a high-risk surgical procedure (Kaarteenaho, 2013). â€Å"The mortality, which can occur shortly after the procedure, has probably been the major reason to refrain from performing SLB† (Kaarteenaho, 2013). With that in mind, diagnosis of IPF includes clinical, radiologic and histopathologic aspects (Wolters, Collard, Jones, 2014). The American Thoracic Society states, â€Å"in the absence of a definitive lung biopsy, the presence of all four major criteria and three minor criteria, as set forth in the current guidelines, increases the likelihood of a correct diagnosis of IPF: Major Criteria †¢Exclusion of other known causes of interstitial lung diseases, such as certain drug toxicities, environmental exposures, and connective tissue diseases †¢Abnormal pulmonary function studies that include evidence of restriction (reduced vital capacity often with an increased FEV:FVC ratio) and impaired gas exchange (increased AaPO2 with rest or exercise or decreased DLCO) †¢HRCT scan showing bibasilar reticular abnormalities with minimal ground-glass opacities †¢Transbronchial lung biopsy or BAL showing no features to support another diagnosis Minor Criteria †¢Age >50 years †¢Insidious onset of otherwise unexplained dyspnea on exertion †¢Duration of illness greater than or equal to 3 months †¢Bibasilar inspiratory crackles (dry or â€Å"Velcro-like† in quality)† (Raghu et al., 2011). The physical assessment is an important part of diagnosis, however, symptoms can mimic other diseases and make it hard to differentiate (Meltzer Noble, 2008). Attention should be paid to key risk factors such as work related inhaled chemical exposure and smoking. Fine inspiratory â€Å"Velcro-like† crackles can be heard upon examination and advance towards the upper airway as the disease progresses (Meltzer Noble, 2008).Clubbing of the fingers and toes is found in 50% of patients (Meltzer Noble, 2008). Lab results are often inconclusive to IPF, but as part of a puzzle can help to identify the disease. An ABG will more than likely read normal (Meltzer Noble, 2008). The pulmonary function test (PFT) can lend valuable information to diagnosing IPF. While IPF is a restrictive disease, it can often imitate obstructive disorders or congestive heart failure (CHF) (Meltzer Noble, 2008). â€Å"Routine spirometry reveals decreased measures of forced vital capacity (FVC) and forced expiratory volume in one second (FEV1). The ratio of FEV1/FVC remains normal (or increased) in IPF, consistent with restrictive physiology† (Meltzer Noble, 2008). Subsequently, the PFT can also reveal reduced TLC, RC, and RV. Reduced gas transfer may also be noted with a DLCO (Meltzer Noble, 2008). Almost every patient with Idiopathic Pulmonary Fibrosis will have abnormal radiological findings (Meltzer Noble, 2008). The imaging modality of choice in diagnosing IPF is High-resolution computed tomography (HRCT) (Hospenthal, 2006). â€Å"Patchy, predominantly peripheral, subpleural, bibasal reticular opacities, often associated with traction bronchiectasis† (Harari Caminati, 2005). A phenomenon referred to as honeycombing is a prevalent finding in IPF, seen below is figure 3. Figure 1: Chest radiograph of a patient with IPF. Chest radiograph reveals peripheral, subpleural reticular opacities, most profuse at the lung bases (Harari Caminati, 2005). Figure 2: Chest HRCT in a patient with IPF. HRCT shows patchy, predominantly peripheral, subpleural, bibasal reticular abnormalities, traction bronchiectasis and bronchiolectasis and irregular septal thickening. There is also ground glass (Harari Caminati, 2005). Figure 3: Chest HRCT in a patient with IPF. HRCT shows predominantly peripheral and subpleural fibrosis with honeycombing (Harari Caminati, 2005). Complications Idiopathic pulmonary fibrosis is a highly progressive disease. Because the tissues in the lungs are scarred, they cannot properly exchange gas and the low amount of oxygen delivered to the body causes several complications and puts strain on the right side of the heart. According to the America Thoracic Society, â€Å"There is an increasing awareness of complications and comorbid conditions frequently associated with IPF† (Raghu et al., 2011). Some of the most common complications are: Pulmonary hypertension, cor pulmonale, respiratory failure and lung cancer (Daniels, Yi, Ryu, 2008). Depression is also often seen in people with IPF because of its devastating prognosis (â€Å"Living With Idiopathic Pulmonary Fibrosis NHLBI, NIH,† n.d.). Acute exacerbations (unexplained worsening of dyspnea) of IPF represent the most destructive and deadly complication (Raghu et al., 2011). â€Å"It is presently unclear if acute exacerbation of IPF is simply a manifestation of an unid entified respiratory complication (such as pulmonary emboli, infection) contributing to an acute worsening in a patient with IPF or represents an inherent acceleration in the pathobiological processes involved in IPF† (Raghu et al., 2011). Medical Management There is currently not a cure for idiopathic pulmonary fibrosis (â€Å"What Is Idiopathic Pulmonary Fibrosis? NHLBI, NIH,† n.d.). Until recently, primary methods of management have been anti-inflammatories and lung transplants (Dempsey, Kerr, Gomersall, Remmen, Currie, 2006). While Anti-inflammatory are still used today it is not due to the effectiveness of treatment, but lack thereof for alternatives (Dempsey et al., 2006).â€Å"Immunosuppressive or cytotoxic agents are used among steroid nonresponders, patients experiencing serious adverse effects from corticosteroids, and patients at high risk for corticosteroid complications† (Harari Caminati, 2005). â€Å"Single-lung transplantation results in an actuarial survival of 73% at 1 year and 57% at 3 years† (Harari Caminati, 2005). Unfortunately, most patients are not eligible for transplant due to age or comorbidity factors (Harari Caminati, 2005). In the spring of 2014 the FDA announced two new drugs for the management of IPF (â€Å"CPF Celebrates Historic Year of Progress in Pulmonary Fibrosis | Coalition For Pulmonary Fibrosis Coalition For Pulmonary Fibrosis,† n.d.). Ofev (nintedanib) and Esbriet (pirfenidone) were both shown to slow the progress of IPF in clinical trials. â€Å"Pirfenidone is a transforming growth factor-beta inhibitor and tumor necrosis factor-alpha inhibitor† (Gohil, 2015). Ofev is a â€Å"fibroblast growth factor receptor (FGFR) antagonist, platelet-derived growth factor receptor (PDGFR) antagonist, and vascular endothelial growth factor receptor (VEGFR) antagonist† (Gohil, 2015). The two treatments are still in the early stages with little known about their effectiveness. Prognosis Prognosis for IPF is dim. It is a fatal disease (Meltzer Noble, 2008). The median survival rate is 3 years after diagnosis (Peljto et al., 2013). Factors associated with â€Å"shortened survival time include: older age, smoking history, lower body mass index (BMI), more severe physiologic impairment, greater radiologic extent of disease, and the development of other complications or conditions, in particular, pulmonary hypertension, emphysema, and bronchogenic cancer† (Ley, Collard, King, 2011). Clinical Trials During the past decade, there has been a notable amount of research into the treatment of idiopathic pulmonary fibrosis. IPF is no longer believed to be due to inflammation, but multiple injuries with atypical cell repair. According to The Coalition for Pulmonary Fibrosis, â€Å"there are many therapies under investigation in clinical trials that include: †¢Antifibrotic or antifibrogenic agents (such as Pirfenidone, interferon and certain blood-pressure-lowering medications) to suppress the scarring process †¢Antioxidants (such as N-acetylcysteine) to prevent damage to lung tissue †¢Monoclonal antibodies to inhibit â€Å"bad† cytokines (protein growth factors, such as TGF-beta, TNF-Alpha, or CTGF, that activate inflammation)† (â€Å"Active Clinical Trials and Investigational Research in IPF | Coalition For Pulmonary FibrosisCoalition For Pulmonary Fibrosis,† n.d.).

The Portrayal of Women in Joseph Conrads Heart of Darkness Essay

Women have gained equality with men over the many centuries of the evolution of the modern western civilization. Hence, it cannot be overlooked that there still exist many literary examples of social disregard for woman potential. Joseph Conrad's "Heart of Darkness" exemplifies the Western patriarchal gender roles in which women are given the inferior status. Not only are women portrayed as being inferior to men, but Marlow's (the protagonist's) seldom mentioning of them in his Congo adventure narrative symbolizes his view of their insignificance. There is a total of five women presented in Marlow's narrative but only three of them are significant minor characters: Marlow's aunt, Kurtz's African mistress, and Kurtz's "Intended." The following essay will examine how the presentation of each of these three women in Marlow's narrative contributes to connecting events in the story. Despite the generalized view of women of his time, Marlow's narrative indicates a more specified view of the value of women which suggest that they are all naà ¯ve but with culturally dependent personas. In presenting female characters, Marlow may have intended to add more essence to his narrative. Nonetheless, each of their appearances and his descriptions of them served to be metaphoric, yet powerful contributions to the story line. From the beginning, Marlow sends a clear message to the reader regarding his position on the image of women. He relates how he "tried the women" after he found no man to help him achieve his travelling and trading ambitions. He did something out of the ordinary for his time; he went to a woman for financial aid. Because this woman is actually his aunt, one might argue that perhaps Marlow is not thankful enough to his... ...he associates her with having powerful qualities, she is still considered naà ¯ve for not having expected departure from Kurtz. She displays sorrow and grief as she throws her hands to the sky as the steamboat pulls away. Finally, Marlow uses Kurtz's Intended to support his view of women as being accurate. In order to save their fantasy worlds, Marlow argues that men can stoop as low as lying. In unique ways the three significant female figures influence the development of Marlow's story but they do not influence the theme of the story; which is Marlow's exploration of the darkness of the human soul. Preserving the "beautiful world" of women as Marlow suggests denies women journey into the Darkness. Their role is therefore limited to their cultural environment and their own world because they might not have the strength to handle all the difficulties and temptation.

The present study attempts to go beyond prior research by using a richer set of non-demographic predictors in the context of gasoline conservation. Multivariate analysis of the predictors suggests that greater understanding of conserver and non-conserver groups can be achieved with a broader set of predictor variables.INTRODUCTION The energy problems first highlighted by the 1973-74 gasoline and fuel oil shortages have spawned a considerable number of research efforts on the topic of energy conservation. Reviews by Anderson and Cullen (1979), Farhar, et al. (1979), Frankena, Buttell, and Morrison (1977), and Joerges (1979) classify over 300 energy consumption studies conducted during the Seventies. A major thrust in many of these studies has been the detection of factors affecting energy conservation.Such a focus on understanding who conserves and why they do so, is of obvious concern for formulating realistic public policies, effectively encouraging energy conservation, and recognizing problems in operationalizing energy conservation plans. However, despite the fact that a number of studies have been directed at finding correlates of energy conservation attitudes and behavior their findings have generally been weak and often contradictory. The following sections review the findings for the major categories of predictors which have been examined and discusses reasons for the inconsistencies.FACTORS RELATED TO INDIVIDUAL ENERGY CONSERVATION Income The one factor most studied for its relationship to energy conservation has been income. Income-related influences on conservation or non-conservation of energy seem to be sufficient to have created a confusing set of findings. Based on general indices or questions about energy conservation behavior some studies have found positive associations between energy conservation and income (Grier, 1976; Talarzyk and Omura, 1974) and between energy conservation and social class (Bultena, 1976).However other studies have found negative associations between energy conservation and income (Cunningham and Lopreato, 1977; Opinion Research Corporation, 1975c) as well as between energy conservation and social class (Gottlieb and Matre, 1975)o Still other studies have found that the middle income classes report the greatest level of energy conservation (Warren and Cliffords 1975; Kilkeary, 1975).And still other studies report no significant relationship between energy conservation and income (Hogan, 1976; Bartel, 1974). The same inconsistent pattern of findings has emerged when conservation of specific type of energy have been examined separately. For home heating conservation, the largest number of studies have found a positive association between income and conservation behaviors (Morrison and Gladhart, 1976; Murray et al. , 1974; Perlman and Warren, 1975a, 1975b; Reizenstein and Barnaby, 1976).Nevertheless, there are again exceptions with some studies showing lower income households conserving more heating fuel (Newman and Day, 1975; WaLker and Draper, 1975) and some showing middle income households conserving more (Warkov, 1976), or that some heating conservation actions are more likely in low income households, while other heating conservation actions are more likely in high income households (Opinion Research Corporation, 1974b).The same inconsistency occurs for studies examining various aspects of gasoline energy conservation, except that in this case the preponderance of evidence sh ows a negative association between income and conservation (Gallup, 1977a; Opinion Research Corporation, 1976b; Roper, 1977a; Barnaby and Reizenstein, 1977; Newman and Day, 1975). The contradictory evidence either shows a positive association (Roper, 1977b; Murray, et al. 1974; Perlman and Warren, 1975a; Reizenstein and Barnaby 1976), a curvilinear association (Warkov, 1976), or no significant association between income and automobile-related energy conservation (Opinion Research Corporation. 1974c). Education The general expectation here would be that education and conservation would be positively associated. However a major complicating factor may be the positive association between education and income.Whether due to this association or to a similarity of energy conservation attitudes across education levels, the studies examining this variable again provide mixed results As expected the largest number of studies have obtained a positive association between education and conserva tion actions (Roper, 1977b; Survey Research Laboratory,1977; Reizenstein and Barnaby, 1976; Thompson and MacTavish, 1976; Gallup, 1977a).The exceptions consist of findings of a curvilinear relationship between education and energy conservation (Cunningham and Lopreato, 1977), findings of a negative relationship (Opinion Research Corporation, 1974a, 1975a, 1975c), and findings of no significant education/ conservation relationship (Murray, et al. , 1974; Hogan, 1976) e Occupation Occupation has been studied less frequently and one reason may be that there is less of an intuitive basis for hypothesizing a relationship between occupation and energy conservation. The studies which have obtained a ignificant relationship between occupation and energy conservation practices and attitudes have found greater conservation by those with higher status occupations (Thompson and MacTavish, 1976; Opinion Research Corporation, 1975d). Other studies have found no differences in energy conservation by different occupational groups (Lowry and Good, 1977; Gallup 1974, 1977a). Some research has found little difference in overall conservation tendencies between occupational groups, but has found the nature of their conservation efforts to differ.For example, one study found that those in business and professional occupations reported a greater tendency to turn down home thermostats in cold weather, while clerical, sales and manual labor workers reported a greater tendency to turn off unused lights at home (Gallup, 1977b); Overall however, occupation does not appear to be a good predictor of energy conservation. Age Given the relationship between age and income, it might be expected that the young and old would find the greatest economic incentive for energy conservation, with less of this motivation among middle ages. But given that many energy-conserving behaviors (e. . walking, bicycling, turning down winter thermostats and turning up summer thermostats) may be less feasible for those in poor health, there are greater constraints acting on older consumers who might otherwise be more inclined to conserve through such behaviors. In terms of baseline rates of energy usage, it appears that middle-aged families (especially with children) have the highest levels of energy consumption, and therefore the greatest opportunity to conserve (Morrison and Gladhart, 1976). These mixed expectations are borne out by mixed findings relating energy conservation and age.For instance, Talarzyk and Omura (1974) report the least resistance to the idea of energy conservation by older consumers, but the greatest number of energy conservation activities by middle age consumers. Cunningham and Lopreato (1977) found the oldest and youngest consumers most likely to conserve, but also found that for some conservation behaviors there was a positive association with age and for others there was a negative age association. While such mixed findings are typical (e. g. Roper, 1977b), other studies report finding no significant relationship between age and energy conservation (Hogan, 1976; KiLkeary, 1975; Bartel, 1974).Thus age has also failed to act as a consistently good predictor of energy conservation. Family Life Cycle As suggested in the comments concerning the related variable of age, larger families with middle aged parents tend to consume larger amounts of energy (Morrison and Gladhart 1976). While this argument suggests greater opportunities for energy conservation by such households, there are also some countervailing forces. One is that a larger, less fuel efficient automobile may be more of a necessity for larger families.Similarly, to the extent that energy conservation requires some sacrifice, it may be more difficult in our society to deprive children of some energy-consuming activity than it is to deprive self or self and spouse alone. But another countervailing force in the opposite direction may be that children receive more conservation information in school than their parents did and bring this information and related conservation attitudes home (Opinion Research Corporation, 1976b). Once again we are left with unclear expectations about the relationship of the family life cycle variable and energy conservation.Even within the area of gasoline conservation, some studies have found conservation more likely among married persons (Burdge, 1975) while others have found conservation more likely among singles (Roper, 1977b). Similarly, some studies have found greater (gasoline) conservation by families with fewer children (Roper, 1977b), while other studies have found greater (general energy) conservation by families with more children (Kilkearny, 1975). Still other studies have found no significant relationship between energy conservation and family composition or size (Hogan, 1976: Morrison 19775.Gender Expectations for the effect of gender on attitudes toward various conservation practices are difficult to formulate. Farhar et al. , (1979) speculate that home-related energy conservation in heating and appliance use may threaten the traditional role of the woman in providing family comfort. However, several studies show women more favorable toward energy conservation in the home than men (Opinion Research Corporation, 1975b, 1976a; Cunningham and Lopreato, 1977). Other studies find no differences in such attitudes (Bartel, 1974). Within the domain of gasoline-conserving ehaviors, some studies show males to be less favorable (Opinion Research Corporation, 1976a) while others show females to be less favorable (Gallup, 1977a). Again the literature fails to uncover consistent relationships between energy conservation and a potential predictor variable. Other Factors Related to Energy Conservation To a lesser extent, other demographic variables have been examined as predictors of energy conservation behavior Race has been examined with some sort of inconsistencies or no difference in behavior result between bla cks and whites (Newman and Day, 1975; Cunningham and Lopreato, 1977).Political party affiliation has also been examined and in some cases Democrats appear more conserving (Opinion Research Corporation, 1975c) and in other cases Republicans appear more conserving (Gallup, 1977a). Urban versus rural area of residence has been examined with little consistency in results. In some studies, rural residents are more conserving (Blakely, 1976; Morrison, 1977), in others urban residents are more conserving (Opinion Research Corporation, 1975d, 1976a), and in others no difference was found (Hogan, 1976).Some studies have gone beyond demographic variables in search for predictors of conservation. One study (Reizenstein and Barnaby, 1976) found media exposure and personal sources of information better predictors of conservation attitudes than demographics. Several studies have used activity, interest, and opinion (AIO) variables to predict energy conservation (Morrison, 1977; Barnaby and Reizen stein, 1977; Talarzyk, 1974). Although the results of these studies have found some significant relationships, the substantial differences in AIO items used preclude any generalization of effects of lifestyle on conservation.REASONS FOR INCONSISTENT FINDINGS Several explanations are possible for the contradictory and inconsistent findings of studies seeking factors related to energy conservation. Two explanations offered by both Farhar et al. , (1979) and Anderson and Cullen (1979), are that there are numerous measures and categorizations of independent variables in these studies and that the dependent variable (energy conservation) has also been operationalized in a number of ways. These do not seem to be adequate to explain all of the anomalies found in the literature.While different categorizations and measures of independent variables may explain why a variable is a significant predictor of conservation in some studies but not in others, it does not explain why the same relation ships are positive in same studies and negative in others. Another explanation which might be suggested is that the samples and time periods of the various studies were different. However, there are also shortcomings to this explanation. The review by Farhar et al. , (1979) finds little in the way of regional differences in energy conservation findings.Even though all relevant studies have been conducted during the 1970's, there may be enough volatility in attitudes and behavior during this period that studies of several different years could obtain different findings. However, the series of longitudinal studies reviewed by Murray et al. , (1974) would seem to discount this argument since most of the variables remained relativelY stable. The foregoing explanations may go part way toward explaining the differences in findings obtained, but there is another more compelling explanation.In nearly every instance there are opposing conceptual expectations concerning the nature of the rela tionship between the predictor variable and conservation of energy. It may well be that the combination of these opposing forces has been sufficient to cause different and even opposite findings in studies with somewhat different samples. Since some of the opposing expectations arise from the correlations between a predictor variable and another variable, a sample which is more homogeneous in such a third variable (e. g. income) than another sample may cause an apparent reversal of the relationship between the predictor variable (e. . education) and energy conservation. With very few exceptions (e. g. Reizenstein and Barnaby, 1976), previous studies have used bivariate rather than multivariate methods in order to examine the relationships of interest. One of the improvements offered in the present paper is to employ a multivariate method in order to go beyond the limitations of the largely bivariate prior studies. In addition, the present paper seeks a richer set of predictor variab les than the largely demographic variables employed in prior research.The primary non-demographic sets of variables added were (1) beliefs about the nature and causes of the energy crisis (often investigated as dependent variables, but not as independent variables), (2) preferences for different energy-related actions, and (3) media exposure variables. No previous study has simultaneously investigated these types of variables. METHODOLOGY In an effort to investigate a wide variety of variables and their effect on gasoline consumption, a sample of 253 heads of households who travel over 150 miles per month was selected using a cluster sampling technique.The data were collected in Salt Lake City, Utah in the spring and summer of 1979 during a period of pronounced shortages and price increases. A structured questionnaire administered by trained interviewers was used to gather information on a variety of potential predictor variables and demographic information. Questions were carefully worded to avoid potential demand characteristics that could result from â€Å"socially acceptable† response options. As discussed above, three primary non-demographic sets of variables were included in the data collection.In addition, current gasoline consumption behaviors and demographic variables were also identified. The five total categories of variables and the dimensions for data gathered in each category are displayed in Table 1. The rationale for choosing to investigate variables in these categories stem from several influences. First, the previous research, discussed at the outset of this paper, tented to narrowly define the potential influences on consumption behavior. The categories used in this study attempt to broaden the base of investigation of potential influences.Second, the types of variables examined in earlier works provided a foundation for the categories of variables used here. Earlier studies were relied on for choosing variables to examine within cate gories. Finally, since there is an issue related to using demographics versus other types of variables to predict energy-related behaviors, demographics were also included in the investigation. RESULTS The main purpose of data analysis was to identify factors that influence gasoline conservation behavior. The initial step in this procedure was to classify respondents as either conservers or non-conservers of gasoline by virtue of various behaviors.The behaviors used to classify respondents were: 1. estimated mpg of the auto being driven 2. consuming less gasoline than six months ago 3. consuming less gasoline than five years ago 4. currently riding in a car pool 5. moving to a residence closer to work to help conserve gas 6. increase in bus usage TABLE 1 NEANS AND UNIVARIATE F SCORES FOR VARIABLES CONSIDERED AS PREDICTORS If a respondent was engaging in two or more conservation behaviors with regard to the above set of variables, the decision rule was to classify this respondent as a conserver.Respondents engaging in less than two conservation behaviors or behaving in a fashion that indicated increased consumption of gasoline were categorized as non-conservers. On the basis of reported behavior, 83 respondents were classified as conservers and 75 as non-conservers. The remaining 95 respondents were unclassified by virtue of demonstrating contradictory conservation and non-conservation behaviors. In an effort to verify this grouping procedure and thereby establish that legitimately different groups were formed by the process 9 a discriminant analysis was performed on the newly formed conserver and non-conserver groups.The discriminant analysis indicated that each of the variables discussed earlier which were used in the group forming process produced significant (p;. 01) differences between conservers and non-conservers. The most important variables in distinguishing the two groups were consumers' use of a more fuel efficient auto and consuming less gasoline th an five years ago. Further verification of the grouping was provided by the classification matrix in this analysis in which a 90. 5% correct prediction was achieved in classifying respondents as conservers or non-conservers versus maximum chance percentage of 52. %. The establishment of groups which were legitimately different in energy related behaviors provided a foundation for investigating a broad set of potential predictor variables. Table 1 shows the means and univariate F-Scores for the complete set of variables considered. The variables in Table 1 were then analyzed using discriminant analysis for their value in predicting the conserver and non-conserver groups. From the original set of 32 variables viewed as potentially useful predictors, Table 2 shows the results of those that were significant in forming the discriminant function.On a univariate basis, many of the variables distinguish between the conserver and non-conserver groups. Additionally, on a multivariate basis th is group of variables provided a highly significant (p< . 001) discriminant function. Further evidence of the overall power of the variable set is provided in Table 3 by the classification matrix. Predicted group membership had a 76. 58% accuracy based on the discriminant function formed from the group of predictor variables (again versus a 52. 5% level by the maximum chance criterion, (Morrison, 1969). TABLE 2 SIGNIFICANT VARIABLES IN DISCRIMINANT ANALYSIS OF CONSERVER GROUPSTABLE 3 CLASSIFICATION MATRIX FOP CONSERVER GROUPS In light of the variables' power in distinguishing between conservers and non-conservers, a discussion of the contribution made by each variable set is worthwhile Beliefs About the Gasoline Shortage This set of predictors indicated consistently different views between conservers and non-conservers. Non-conservers were more prone to believe that no real gasoline shortage existed, that there was less of a need for the country to decrease its consumption of gasoli ne, and that the gasoline availability problem was due to government bungling of the situation.The conserver group tended toward opposite beliefs in each of these areas. The government issue is one of the strongest contributors to the multivariate prediction of group membership. Evaluation of Potential Solutions Univariate comparisons of the two groups on this set of variables indicate that significant differences exist between the groups on two of six dimensions (closing gas stations on certain days as an acceptable solution and higher prices as a best solution).One possible reason greater differences were not discovered in univariate analysis of these factors is that non-conservers were not convinced a shortage of gasoline really existed. In this context, non-conservers may have found it difficult to evaluate potential solutions to a hypothetical problem. Again, on a multivariate basis, each of the variables in this set contributed significantly to the distinction between the grou ps. Gasoline Consumption Behaviors This set of variables identifies differences in the way conservers and non-conservers use their personal automobiles.Non-conservers tented to drive a greater number of miles in a year and had a significantly higher percentage of work related use of the automobile. Given the influence of using the automobile for work related purposes, perhaps non-conservers hold a view that there is an element of inflexibility in their ability to conserve gas. This proposition, however, must be evaluated in the context of the non-conservers' stronger belief that a shortage of petroleum doesn't really exist anyway. Media HabitsThe only media habit that was different between the groups was ratio listening behavior and this is only significant in the context of the multivariate analysis. Data were gathered on television viewing behavior and amount of time spent reading the newspaper. As the data in Table 2 indicates, non-conservers spent more time listening to the radi o (perhaps as part of work related travel). Demographics The demographic analysis in this current study provides a basis for comparison with previous energy conservation research.The results in Table 2 indicate that conservers are younger, and have higher education and income status than non-conservers. The age relationship is more straightforward than suggested by prior research. The significance of the education variable contributes to the body of evidence which suggests a positive association between conservation and education level (Roper, 1976b; Survey Research Laboratory; Reizenstein and Barnaby, 1976; Thompson and MacTavish, 1976; Gallup, 1977a). Conservers were also found to have a higher income than non-conservers.While the difference between groups is not significant on a univariate basis, this is another variable that contributes to the overall differences between the groups on a multivariate basis. In general, the positive association of income to conserver status joins a relatively few previous efforts discovering the same result (Roper 1977b. , Murray et al. ; 1974; Perlman and Warren, 1975a; and Reizenstein and Barnaby, 1976). DISCUSSION First, it may be noted some of the belief, attitudinal, and behavioral predictors are stronger predictors of conserver status than any of the demographic variables.It therefore appears that the inclusion of this enriched set of predictors paid off and that prior studies have been limited by restricting themselves to demographic variables. From a public policy standpoint, the current results indicate that non-conservers simply are not convinced that an energy problem exists. They are clearly more prone to believe that the government is responsible for shortages in petroleum and that decreasing consumption of gasoline will not eliminate the source of the problem.This mentality on the part of non-conservers manifests itself in several ways. The non-conserver group drives less fuel efficient cars and uses car poolin g and public transportation far less than conservers. Further, the non-conserving group has shown little effort over the past six months or five years to consume less gas. The lack of belief in the reality of a gasoline shortage also results in lack of enthusiasm by non-conservers for any potential solutions.Admittedly, the conservers were not overly favorable toward most solutions, but non-conservers did not rate a single potential solution positively as a group. Since not one of 75 respondents classified as non-conservers cited higher gas prices as the best solution to the problem, perhaps this tactic would have the greatest impact on the group. Aside from any attempt to speculate regarding specific policy strategies though, the main conclusion is that this group needs to be convinced of the existence of any energy problem.It can also be recognized that non-conservers drive more miles and drive more for work related reasons than conservers. The implication here could be that non-c onservers consider the consumption of gasoline a necessity and therefore do not feel they have the flexibility to engage in conservation behaviors. Demographically conservers are younger, more highly educated and higher in income than non-conservers. Perhaps, these demographic factors have contributed to their ability to obtain and comprehend information about the energy situation, hereby influencing their beliefs about its existence. This in turn may have influenced conservers to car pool, use public transportation, drive more fuel efficient cars, and generally reduce consumption of gasoline. At least this cognitive-behavioral chain of events is the one we would expect for a high involvement choice like gasoline conservation. The distinctions between conservers and non-conservers Just discussed were, to a large degree, discovered through the use of a multivariate approach to the predictor variables.Many factors that were not significant on a bivariate basis, nonetheless, were signi ficant in the context of a multivariate analysis of the two groups. To the extent that factors are operating in conjunction with one another to influence conservation behavior such a simultaneous investigation appears to have promise in untangling the contradictory findings produced by previous bivariate analyses The task of future research investigating energy conservation behavior is to further enhance and enrich the set of predictor variables by taking into account longitudinal changes in the beliefs and attitudes found to be important in this study.To the extent that evolving consumer beliefs about energy problems and consumer consumption behaviors related to these beliefs can be identified, a greater understanding of factors influencing conservation behavior will be attained.
