No / Mental ill health in the workplace is a high profile issue, but what are the starting points for successful policies and interventions?

This dissertation offers an empirical examination of the relationship between community social capital and health care safety net capacity. The ability and willingness of federally qualified health centers (FQHCs) and private physicians to serve the uninsured is crucial to ensuring that all Americans have access to a basic level of health care. Among other factors, this ability and willingness has been found to be a consequence of unique community values and traditions. This dissertation examined the extent to which the level of community social capital (community rates of participation in club meetings, projects, volunteer and civic activities) was related to three health care provider outcomes; 1) the willingness of private physicians to deliver uncompensated care; 2) the financial capacity of FQHCs to provide uncompensated care; and 3) the amount of FQHC resources directed toward the provision of largely uncompensated community-oriented services.Community and health care provider data on 1,248 FQHCs across 183 U.S. counties and 12,406 private physicians across 1,029 U.S. counties were collected from multiple data sources. Comprehensive multivariate analyses including Canonical Correlation Analysis (CCA), Ordinary Least Square (OLS) and Hierarchical Linear Modeling (HLM), and a planned comparison was conducted on these data at the community ecological and individual provider levels of analysis.Based on a literature review and the theoretical components of social capital theory, I developed a conceptual framework that proposed a relationship among social context, institutional frameworks and organizational behavior. The dissertation research sought to determine the extent to which the social context in which the organization was embedded influenced organizational behavior.I found that the relationship between community social capital and health care safety net capacity was weak and the direction of the association mixed. Among the findings was a positive and significant relationship between civic participation and FQHC grant revenues. Unexpected findings included significant correlations between community social capital and Medicaid generosity, and social capital and uninsurance. Although the data analysis suggested that unmeasured factors were largely responsible for variation in safety net capacity, it raised interesting questions that provoke future study. Important implications for theory, policy and practice are discussed.

The research objectives were:- 1.To review the literature to establish the factors which have traditionally been regarded as most crucial to the design of effectlve exhaust ventilation systems. 2. To design, construct, install and calibrate a wind tunnel. 3. To develop procedures for air velocity measurement followed by a comprehensive programme of aerodvnamic data collection and data analysis for a variety of conditions. The major research findings were:- a) The literature in the subject is inadequate. There is a particular need for a much greater understanding of the aerodynamics of the suction flow field. b) The discrepancies between the experimentally observed centre-line velocities and those predicted by conventional formulae are unacceptably large. c) There was little agreement between theoretically calculated and observed velocities in the suction zone of captor hoods. d) Improved empirical formulae for the prediction of centre-line velocity applicable to the classical geometrically shaped suction openings and the flanged condition could be (and were) derived. Further analysis of data revealed that: - i) Point velocity is directly proportional to the suction. flow rate and the ratio of the point velocity to the average face velocity is constant. ii) Both shape, and size of the suction opening are significant factors as the coordinates of their points govern the extent of the effect of the suction flow field. iii) The hypothetical ellipsoidal potential function and hyperbolic streamlines were found experimentally to be correct. iv) The effect of guide plates depends on the size, shape and the angle of fitting. The effect was to very approximately double the suction velocity but the exact effect is difficult to predict. v) The axially symmetric openings produce practically symmetric flow fields. Similarity of connection pieces between the suction opening and the main duct in each case is essential in order to induce a similar suction flow field. Additionally a pilot study was made in which an artificial extraneous air flow was created, measured and its interaction with the suction flow field measured and represented graphically.

The thesis examines the system of occupational health and safety in France. It analyses the use of expert manpJwer in the field with a view to establishing the pJssibility of a profession in health and safety. An input-output model is developed to bring together the necessary elements of prevention of accidents and occupational diseases. The role of institutions concerned with health and safety is analysed with reference to this model. The research establishes the need for a health and safety specialist role. The recognition and status of this role are found to be subject to other criteria including the acceptance by institutions of such a specialist role. The model is also used to define the role of this specialist as expected by the various institutions intervening in the field.

Abstract Purpose: To determine the prevalence and factors associated with injury in professional ballet and modern dancers, to explore dancers’ attitudes and perceptions of injury, and to assess if dancers are reporting their injuries and reasons for not reporting injuries. Methods: A cross-sectional survey was undertaken in professional ballet and modern dance companies in Canada, Denmark, Israel, and Sweden. Results: The point prevalence of injury in dancers is high (55% ballet; 46% modern) and most have chronic pain. Years dancing professionally and rank were associated with injury in ballet dancers. Attitudes towards injury vary and some dancers are continuing to dance when injured. Greater than 15% of all injured dancers have not reported their injury. Conclusions: Injury is common in dancers and there is an urgent need to investigate interventions to help control injury and understand the long-term implications of these conditions in this population.

Agriculture challenges health and safety professionals as it continues to be one of the most dangerous occupations despite the considerable attention that has been paid to it. Researchers have struggled to obtain the information necessary to challenge the cultural, economic and family dynamics that seem resistant to change. To add to this difficulty, attention has not been paid to the concerns of the farm women who work off the farm while taking care of children and supporting their husbands. This research process has resulted in viewing the women as women, not as wives. This qualitative research proposal used feminist methodology to study the perspectives of farm women through the focus group process. Data was collected and an analysis performed using the transcripts. Ultimately, meaning emerged from the collective lived experience of these farm women. The farming community hopefully will benefit from this research through the creation of better safety interventions targeted to the farm wife in the future.
