Background: Employees are the human capital which contributes to the success and de-velopment of a company to a great extent. Thus, these days, companies do not see them only as factors of production from the classical perspective, but have started to value them as stakeholders and partners with whom long-term goals are achieved together. Problem Discussion & Purpose: Researchers realized the need of companies to deal with employees, and for that reason, there has been great time and effort spent on studies con-cerning the relation between job satisfaction and job performance. However, the authors of the thesis came to conclusion that the link between job satisfaction and job performance was still a vague one. Therefore, the thesis is focused on the concept of well-being. The study concentrates on blue-collar workers, and the purpose is to explore and understand the relation between job-related well-being and employees’ job performance in the context of stress caused by following environmental factors: working tools, workload, heat, noise, and safety. Theoretical Framework: The theories used for this study are concerning job perform-ance, well-being, and stress. An emphasis is given on the work environmental stressors, which are working tools, workload, safety, heat, and noise. Methodology: To make this study, the researchers applied qualitative approach and used 8 semi-structured interviews to collect the data. The authors have conducted personal “face-to-face” interviews. All of them were tape-recorded to provide the maximum accuracy of received data. Information was gathered within one company. Conclusion: After conducting research, acquiring empirical findings, and making analysis of data, the thesis authors suggest that there is a link between job performance and job-related well-being via the work environment stressors. The authors of the thesis assume that probably the relationship between well-being and performance can look as a “circle-” or “spiral”-like model, where well-being and performance influence each other mutually, however, in different ways at different stages of the model. The influence of well-being on job performance via researched work environment stressors can be either direct or indirect. The study is of a great importance because it gives good insight of seeing well-being as a link to performance which previously was not done by any other research. Being aware of the influence of the environmental factors, managers can better realize how these factors contribute to the performance and well-being of their employees, and find ways how to improve working environment in order to increase workers’ job performance and job-related well-being.

When animals are stressed they use a trait called social support to alleviate their stress responses. With domestication many traits from the ancestor red junglefowl have changed in the domesticated breed white leghorn. White leghorns are bred to be able to live in large groups where it becomes hard to recognize every chicken. They are therefore not as dependent of familiar stimuli birds for social support as red junglefowl. Our hypotheses were that red jungle males would be more interested in unfamiliar stimuli birds than white leghorn male before stress due to their territoriality. We tested total 56 chickens in an open field test. The test arena was divided in three zones and the time the focal birds spent in each zone was recorded. The focal bird was recorded in 300 seconds before being stressed by being suspended in a net and then recorded again in 300 seconds. The results showed that social support and social behaviour differs between females and males for both breeds. No significant differences were found between the breeds. There was a tendency for significant of breed (P=0.08) effects in the central zone unstressed. The two interactions before stressed between breed and sex, central zone (P<0.01) and unfamiliar zone (P<0.01) had significant effects. We observed fights between white leghorn males and familiar stimuli. Waltzing did also occur in red jungle males in front of unfamiliar. In conclusion, numeric differences can be seen but not large enough to be significant and our hypotheses are not confirmed.

Expatriates are the representative of parent companies in overseas subsidiaries. Expatriates¡¦ stress would impact to both company and their personal life. To help multinational companies decrease work stress of expatriates and manage work stress problem, the objective of this research is to find personal characteristic factors affecting work stress of overseas expatriates in Thailand. The questionnaires were distributed to 120 respondents, valid samples are 105 persons. The finding shows that there is no significantly different in work stress between male and female expatriates, divorced respondents have work stress more than single and married group, elder expatriates more concern with stressors than younger expatriates, and stressor caused stressful to managers more than officers. ¡§Lack of training¡¨ and ¡§reward and compensation¡¨ are stressors respondents most concern. Therefore, supporting and training program are the things that expatriates expect from parent company. To decrease expatriates¡¦ work stress, company should provide pre and post departure program, language training program, and prepare suitable facilities to fit expatriates needs during their overseas assignments.

BACKGROUND¡GWork plays an important role in everyone¡¦s health and happiness. However, facing the rapidly changing medical environment, physicians feel even more stress than ever. PURPOSE¡GThe purpose of this study was to find the current stressors among physicians who worked in hospitals in southern Taiwan, and to evaluate the correlations among demographics, type A behavior pattern(TABP) and the perception and approach-avoidance intention (AAI) of the stressors. METHOD: Structured questionnaires were mailed to physicians who worked in hospitals in Ping tong and Kaohsiung. Data were coded and analyzed with factor analyses, £q2 test, Pearson¡¦s correlation, partial correlation, Student t test, ANOVA and multiple regression when appropriate. RESULTS: The effective response rate was 7.9% and there was no true difference between the samples and population in demographic characteristics. Six factors were extracted from stressors by factor analyses with the cumulative percentage of total variance explained around 64.7%. The overall Cronbach¡¦s £\ was .917. The extent of stress perception and the AAI of the factors of stressors, namely ¡§patient management (PM)¡¨, ¡¨interpersonal relationship (IR)¡¨, ¡¨work load (WL)¡¨, ¡¨medical environment (ME)¡¨, ¡¨organizational structure (OS) and ¡§research and teaching (RT)¡¨, were used as dependent variables during comparisons between different demographic variables and TABP. The mean TABP score was 4.47, mean perceived stress was 3.13 and the mean AAI of the stressors was 3.5. The most stressful factor of stressors was PM and the least was IR. The AAI of the factor of the stressors revealed that RT was most likely to use approach as the coping strategy whereas the OS was the least. The correlation between the extent of the stress perception and AAI of the stressors varied. Significant correlation was found only in moderate stress zone. TABP significantly correlated to stress perception with Pearson¡¦s r = .227 ( P < .05 ). There was significant difference in overall stress perception on TABP and the position of the physicians. Physicians with TABP perceived more stress than Type B did. Residents were more likely to report their job as stressful than attending physicians did. However, the correlation between TABP and the AAI of the stressors (overall and all 6 factors) were not significant. The attribute of the hospital was the only factor that has the moderator effect on AAI of the stressors. Physicians who worked in public hospitals use approach as the coping strategy to the stressors more likely than physicians who worked in private hospitals did. The correlation between the stress perception and AAI to the factors of the stressors, and the moderator effect of physicians demographics and TABP on stress perception and AAI to the factors of the stressors will be discussed in detail in the text.

Fetal programming results from stressors during fetal development and may influence the occurrence of disease later in life. Maternal nutritional status and/or environment can affect renal development by inducing limited nephron endowment at birth, which results in diseases such as hypertension and coronary heart disease in mammals. Birds are likely to be effective models for this process because, like mammals, they have high pressure cardiovascular systems, mammalian-type nephrons and are homeothermic. This project uses the chicken embryo to explore physiological responses of disrupted hydration state thereby providing insights into renal fetal programming. Under normal conditions the chorioallantoic membrane (CAM) and developing avian kidney work in unison to ensure a proper balance of ions and water within the egg. White leghorn chicken eggs were incubated at 37.5oC±0.5oC and either <35%, 55-60% (normal) or >85% relative humidity. Amniotic fluid serves as the drinking source for the embryo late in development; its composition is important to salt and water homeostasis. High amniotic fluid osmolality increased the blood osmolality for embryos exposed to low humidity incubation thereby indirectly influencing the renal developmental program of the embryos from this group. Indeed estimated filtering capacity was doubled in the low humidity group (6.77 ± 0.43 mm3) compared to normal (4.80 ± 0.33 mm3) and high (3.97 ± 0.30 mm3) humidity groups. The increased filtering capacity seen for those embryos from low humidity may indicate the ability for more efficient recovery of water if similarly stressed as an adult bird. All embryo populations maintained similar oxygen consumption (0.075 ml/min - 0.37 ml/min), hematocrit (15 % - 32 %) and hemoglobin values (4 g/dl - 9 g/dl), thus displaying control over these aspects of the internal environment despite the obvious environmental insult of extreme incubation humidity. These results signify the embryo's immature kidney, along with lower gastrointestinal tract, functions much like the adult form maintaining homeostasis, although the mechanisms may differ. The overall benefits of this research included better understanding of the role the kidney during embryonic development and determining whether environmental factors, such as humidity, leave an imprint on morphological and physiological aspects of the urinary system of the embryo and water compartments of the egg.

The objective of this study was to describe the experiences of hearing children as they cope with having a sibling with deafness. From a constructivist point of view, this research process is seen as socially constructing a reality or realities, with the researcher included in, rather than outside the borders of his or her own research. Semi-structured and unstructured interviews were conducted with the subjects. These interviews were aimed at obtaining information regarding the subject’s experience of the stressor of having a sibling with deafness. The participants reported limited family interaction. Although most siblings say that they have good relationships with their siblings with deafness, their primary feelings indicate that there are aspects of having a sibling with deafness that can be challenging. The participants described experiencing a variety of feelings which include the following: frustration, loneliness, anger, affection, resentment and pity. The results of this study have shown that the siblings of children with deafness, need more professional support in terms of coping with the disability and its consequences. Siblings need guidance on active coping responses in coping with the stressor of having a sibling with deafness. / Dissertation (Magister Artium (Counselling Psychology))--University of Pretoria, 2007. / Psychology / unrestricted

The Red Sea is one of the warmest, saltiest, and most oligotrophic seas in the world that supports a healthy and extremely diverse coral reef ecosystem. Increasing development along the Saudi Arabian coast may increase eutrophication due to impacts of human population and also oil pollution from increased shipping traffic and refinery activity. The risk of oil pollution combined with increased eutrophication due to coastal development provides a clear stressor interaction which is vastly understudied. Individually, these stressors are known to negatively impact coral reproduction, recruitment, and growth. This study focuses on reef settlement and recovery following experimentally-simulated disturbance scenarios. Carbonate recruitment tiles were placed on the reef and exposed to four treatments: control, nutrient enrichment with slow-release fertilizer, tiles soaked in crude oil, and a combination treatment of nutrient enrichment and oil-coated tiles. At periods of 3, 6, 9, 14, and 17 weeks, tiles were collected to classify the settled community and measure oxygen production. Oil, nitrate, and phosphate were the biggest determining factors predicting settlement and oxygen production of the different treatments. The oil treatment had the least overall settlement and oxygen production, whereas the nutrient treatment had the most turf algal recruitment and oxygen production. The combination treatment had an antagonistic effect on algal growth: the nutrients facilitated growth on the otherwise toxic oiled tiles.
