Does Drinking Really Decrease in Bad Times?

This paper investigates the relationship between macroeconomic conditions, alcohol use, and drinking problems using individual-level data from the 1987-1999 years of the Behavioral Risk Factor Surveillance System. We confirm the procyclical variation in overall drinking identified in previous research using aggregate sales data and show that this largely results from changes in consumption among existing drinkers, rather than movements into or out of drinking. Moreover, the decrease in alcohol use occurring during bad economic times is concentrated among heavy consumers, with light drinking actually increasing in these periods. We find no evidence that the decline in overall drinking masks a rise in alcohol use for persons becoming unemployed during contractions, suggesting that any stress-induced increases in consumption are more than offset by reductions resulting from changes in economic factors such as lower incomes.

Dairy Farm Revenue Insurance: Is the Application Viable?

An Examination of US Consumer Pet and Veterinary Expenditures, 1980-1999

The veterinary medical profession touches nearly everyone's life, either directly or indirectly. An estimated 58.3% of US households own pets (AVMA, 2002), and most people consume livestock products in the form of meat, dairy products, wool, or leather. The health and well being of all these animals depend heavily on relationships with veterinarians. Veterinarians also contribute to public health through the FDA, CDC, USDA, and numerous other government agencies at the federal, state, and local levels. Issues of primary concern include food safety, biosecurity, and the numerous emerging (and re-emerging) infectious diseases that are zoonotic in nature. Finally, veterinarians have an additional impact through their research contributions. Virtually all of the laboratory animals used in research are raised, housed, and managed under the care of veterinarians, and veterinary researchers regularly provide valuable contributions to the knowledge base in the biomedical sciences. This study was designed to assess the general trends in pet and veterinary expenditures as well as factors associated with pet ownership and expenditures on veterinary medical services. Providing such key information on the sector of greatest economic importance will enhance the probability of sustained economic viability in the veterinary medical profession as a whole.Health Economics and Policy,

Detection of Interstellar C_2 and C_3 in the Small Magellanic Cloud

We report the detection of absorption from interstellar C_2 and C_3 toward the moderately reddened star Sk 143, located in the near 'wing' region of the SMC, in optical spectra obtained with the ESO VLT/UVES. These detections of C_2 (rotational levels J=0-8) and C_3 (J=0-12) absorption in the SMC are the first beyond our Galaxy. The total abundances of C_2 and C_3 (relative to H_2) are similar to those found in diffuse Galactic molecular clouds -- as previously found for CH and CN -- despite the significantly lower average metallicity of the SMC. Analysis of the rotational excitation of C_2 yields an estimated kinetic temperature T_k ~ 25 K and a moderately high total hydrogen density n_H ~ 870 cm^-3 -- compared to the T_01 ~ 45 K and n_H ~ 85-300 cm^-3 obtained from H_2. The populations of the lower rotational levels of C_3 are consistent with an excitation temperature of about 34 K.Comment: accepted to MNRAS; 10 pages, 6 figure

Incorporating Environmentally Compliant Manure Nutrient Disposal Costs into Least-Cost Livestock Ration Formulation

Livestock rations are formulated to minimize feed cost subject to nutritional requirements for a target performance level, which ignores the potentially substantial cost of disposing of nutrients fed in excess of nutritional requirements. We incorporate nutrient disposal costs into a modified least-cost ration formulation model to arrive at a joint least-cost decision that minimizes the sum of feed and net nutrient disposal costs. The method is demonstrated with phosphorus disposal costs on a representative dairy farm. Herd size, land availability and proximity, crop rotation, and initial soil phosphorus content are shown to be important in determining phosphorus disposal costs.environmental compliance, linear programming, livestock rations, manure disposal, Agribusiness, Environmental Economics and Policy, Livestock Production/Industries, C61, Q12, Q52,

Increased daily physical activity and fatigue symptoms in chronic fatigue syndrome

Individuals with chronic fatigue syndrome (CFS) have been shown to have reduced activity levels associated with heightened feelings of fatigue. Previous research has demonstrated that exercise training has beneficial effects on fatigue-related symptoms in individuals with CFS. PURPOSE: The aim of this study was to sustain an increase in daily physical activity in CFS patients for 4 weeks and assess the effects on fatigue, muscle pain and overall mood. METHODS: Six CFS and seven sedentary controls were studied. Daily activity was assessed by a CSA accelerometer. Following a two week baseline period, CFS subjects were asked to increase their daily physical activity by 30% over baseline by walking a prescribed amount each day for a period of four weeks. Fatigue, muscle pain and overall mood were reported daily using a 0 to 100 visual analog scale and weekly using the Profile of Mood States (Bipolar) questionnaire. RESULTS: CFS patients had significantly lower daily activity counts than controls (162.5 ± 51.7 × 10(3 )counts/day vs. 267.2 ± 79.5 × 10(3 )counts/day) during a 2-week baseline period. At baseline, the CFS patients reported significantly (P < 0.01) higher fatigue and muscle pain intensity compared to controls but the groups did not differ in overall mood. CFS subjects increased their daily activity by 28 ± 19.7% over a 4 week period. Overall mood and muscle pain worsened in the CFS patients with increased activity. CONCLUSION: CFS patients were able to increase their daily physical activity for a period of four weeks. In contrast to previous studies fatigue, muscle pain, and overall mood did not improve with increased activity. Increased activity was not presented as a treatment which may account for the differential findings between this and previous studies. The results suggest that a daily "activity limit" may exist in this population. Future studies on the impact of physical activity on the symptoms of CFS patients are needed

Evaluation of thermal evaporation conditions used in coating aluminum on near-field fiber-optic probes

This is the published version, also available here: http://dx.doi.org/10.1063/1.1148836.The effects that the thermal evaporation conditions have on the roughness of aluminum-coated near-field fiber-optic probes were investigated using the high-resolution capabilities of atomic force microscopy. The coating conditions studied include the effects of background gas composition, base vacuum pressure, and aluminum evaporation rate. The effects of aging on the aluminum-coated tips were also evaluated. The results from topography measurements of the resulting aluminumfilm indicated that the most dramatic improvements in the tip coatings can be achieved using high aluminum evaporation rates at base vacuum pressures below 10−5 Torr. These results agree with other studies on thin aluminumfilms and reflect a decrease in oxide formation. For demanding applications of near-field microscopy requiring maximal resolution, the results presented here indicate that it may also be necessary to reduce oxygen and/or water from the vacuum chamber prior to coating

A mixed methods study on the impact of the perceived aesthetics of a workplace

Interventions which change the visual appearance of the work environment to positively impact employee and organizational outcomes are becoming increasingly common. For example, environmental interventions such as adding indoor plants, changing the color of the walls, and increasing the amount of artwork within a workplace can lead to reduced stress levels, anxiety, fatigue, and sick leave (Dijsktra, Pieterse, & Pruyn, 2008a; Dijkstra, Pieterse & Pruyn, 2008b; Nejati, Rodiek, & Shepley, 2016). However, more research is needed to discover exactly why changing the appearance of work environments have a positive effect and what factors may influence the effectiveness of these interventions. There is theoretical and empirical support for the notion that the benefits of these interventions are in part due to the increased aesthetics of the environment. For example, Maslow (1954) wrote of a need for aesthetics, Kaplan & Kaplan (1989) argued that the aesthetic component of an environment can help individuals recover from mentally draining experiences, and Dijstrka, Pieterse, & Pruyn (2008) found that adding indoor plants to a room had positive psychological benefits due to the increase in the perceived attractiveness of the room. In this study, we seek to examine the impact that the perceived aesthetics of a workplace and the prevalence of aesthetic elements have on full time adult employees’ post work recovery needs, turnover intention, and job satisfaction. Additionally, we seek to examine if individual’s need for an aesthetically pleasing workplace and mindfulness levels moderate these relationships. Our ultimate goal with this work is to offer a model and methodological approach that can be useful to those interested in studying the impacts of the appearance of a workplace on employee job satisfaction, stress, and intention to stay at their job. A better understanding of this relationship will allow organizations to more effectively change the workplace to have greater positive impacts on employees’ health and happiness. This research comprises of two phases. First, participants complete a survey that measures relevant variables such as mindfulness levels, need for an aesthetically pleasing workplace, individual differences (e.g., personality), and asks them to identify any aesthetically pleasing visual elements that are present in their workplace (e.g., plants, artwork, colorful walls). If participants consent to continue to phase two, they will be asked to upload three photos of their workplace. These photos will be thematically coded to identify what elements are frequently present in environments that are rated as aesthetically pleasing

A noble task: Testing an operational model of clergy occupational health

In many ways, clergy and religious leaders are an ignored yet high-risk population. In their efforts to ensure the spiritual well-being of their congregations, clergy frequently neglect their own well-being, resulting in stress and burnout, which then can lead to impaired health. This neglect often extends to clergy’s family and congregation. Church members typically seek help from clergy to cope with the loss of loved ones, life crises, and other general life stressors. A clergy member unable to cope with these same challenges in his or her own life may be ineffective at helping church members to cope with their stress. Recent theory applications and measure development efforts in this research space have led to several studies of specific occupational hazards or challenges faced by clergy. These challenges include high job demands, congregational criticism, and isolation; restoration following moral failures (e.g., alcohol abuse, adultery); and resolving conflict among congregation members . Furthermore, a holistic model of clergy health functioning has been proposed, which includes specific occupational challenges and their detrimental effects on clergy health. Unfortunately, the constructs in this model are more theoretical than operational. While such a model is useful for conceptualizing the factors that influence clergy health, an operational model of clergy holistic health is still needed to empirically test the effects of occupational demands, and personal and job-related resources on the health of clergy. The purpose of the present study, therefore, is to develop and test such a model. The ultimate goal of this research is to offer a model and methodological approach that can be useful to those interested in better identifying and addressing the health and well-being needs of clergy so that they may thrive in their roles to the betterment of their families and congregations
