This research explores the understanding of psychosocial risks and work-related stress by international multi-disciplinary experts in developing countries. It further explores their views on the perceived health impact of these issues. It identifies preliminary priorities for action while considering similarities and differences in conceptualizing these issues in industrialized and developing countries. Finally, it explores in what ways these issues can enter the policy agenda in developing countries. This research applies a triangular methodological approach where each stage provides the basis for the development of the next. It starts out with 29 semi-structured interviews to explore the views of experts and also to inform two rounds of an online Delphi survey, which then informed four focus group discussions. The total sample amounted to 120 participants (each sampled once). Key findings for developing countries indicate that a) psychosocial hazards need addressing due to an impact on workers' health; b) occupational health and safety priorities have changed during the last decade pointing to the need for monitoring of psychosocial hazards and the need to address work-related stress, violence, harassment and unhealthy behaviours together with other workplace hazards; c) socio-economic conditions and processes of globalization need attention in the study of psychosocial hazards and an extended research paradigm is required; and d) there is an ever present need for capacity building, stakeholder mobilization, infrastructure development and international exchange and collaboration to address all workplace hazards. Developing countries are not spared from the health and economic impact of psychosocial risks and work-related stress, and there will be a need to address these issues through policy development. To pave the way, this dissertation outlines a need for concerted action at different levels.

Introduction Regular cycling has been shown to improve health and well-being and has a role in tackling obesity and inactivity. Cycle collisions, particularly those involving motorised vehicles, can lead to significant mortality and morbidity and are currently a barrier to wider uptake of cycling. There is evidence that the conspicuity of cyclists may be a factor in some injury collisions. Low-cost, easy to use retro-reflective and fluorescent clothing and accessories (’conspicuity aids’) are widely available. Their effectiveness in reducing the risk of cycling collisions is currently unknown. This study was designed to investigate the relationship between the use of conspicuity aids and risk of collision or evasion crashes for utility and commuter cyclists in an urban setting in the UK. Methods A matched case-control study was undertaken. Cases were adult commuter and utility cyclists who were involved in a crash resulting from a collision or attempted evasion of a collision with another road user. Cases were recruited at a large UK emergency department. Controls were commuter and utility cyclists matched by time and day of travel, season and geographical area of cycling. Controls were recruited at public and private cycle parking sites. Data on the use of conspicuity aids, crash circumstances, participant demographics, cycling experience, safety equipment use and journey characteristics including an estimate of the bicycle crash risk for each chosen route (the number of previous crashes per 100 million kilometres travelled by bicycle calculated for each participant route) were collected using self-completed questionnaires and maps. Conditional logistic regression was used to calculate crude and adjusted odds ratios and 95% confidence intervals of the risk of a crash involving a collision or evasion of a collision with another road user when cyclists reported they were using any item of fluorescent or retro-reflective clothing or equipment vs. none. Unconditional logistic regression was used to analyse associations between participant characteristics and conspicuity aid use. Continuous variables were dichotomised where there was a non-linear relationship to the bicycle crash outcome variable or the primary exposure variable. The sensitivity of the study models to selection, recall and information biases and the effect of missing data was assessed using independent records of conspicuity aid use by potential participants during recruitment. Observations of conspicuity aid use within the study source population at sites across the study catchment area were also conducted by the researcher during the recruitment phase. Results There were 76 cases and 272 controls cyclists who were eligible for inclusion in the primary analysis (response rate of 13% and 54% respectively). The proportion of cases who reported using any item of fluorescent or reflective materials on their clothing or equipment (excluding bicycle mounted reflectors) was higher than for matched controls (cases users 69.7%; 95% CI 58.1% to 79.8% vs. control users 65.4%; 95% CI 59.5% to 79.1%). The unadjusted odds ratio for a collision or evasion crash when using conspicuity aids, was 1.2 (95% CI 0.66 to 2.17). Two alternative modelling strategies were employed. After adjustment for confounding from age, gender, socio-economic deprivation, number of years of cycling experience, bicycle crash risk along each route and cycle helmet use the odds ratio was 1.77 (95% CI 0.74 to 4.25). After adjustment for confounding from age, gender, socio-economic deprivation, bicycle crash risk along each route and history of previous cycle crash involvement the odds ratio was 2.4 (95% CI 1.06 to 5.7). The odds ratio was not significantly affected by adjustment for possession of a driving licence, reported bicycle safety training in childhood, psychometric associates of risk taking behaviour, cycle helmet wearing, years of experience of cycling, distance or number of trips cycled in the previous seven days, type of bicycle, the use of bike-mounted lights or reflectors, weather or lighting conditions, familiarity with the route or alcohol consumption within 8 hours prior to the recorded journey. There was a significant difference between the measure of bicycle crash risk along each route for cases and controls with controls reporting travelling on routes with lower objective bicycle crash risk (median (IQR); cases 378.5 (232.4 to 548.3) vs. controls 268.5 (192.6 to 464.5); p= 0.006). There were no significant differences in route risk for users vs. non-users of conspicuity aids (route risk median (IQR) for conspicuity aid users vs. non-users; 308.1 (198.0 to 504.3) vs. 272.3 (203.7 to 413.4; p= 0.22). Conspicuity aid use was associated with increased length of participant route (unadjusted OR 3.25 for reported route greater than median; 95% CI 2.04 to 5.17 p<0.001), higher numbers of police-recorded bicycle crashes (unadjusted OR 2.26 for greater than median; 95% CI 1.43 to 3.55; p<0.001) and lower numbers of observed cyclists on each route (unadjusted OR 0.999; 95% CI 0.998 to 1.000 p=0.015). Route risk data were missing for 50 participants (15 cases and 35 controls). Validation of the primary exposure showed that there was moderate agreement between participants’ self-reports and independently collected data (kappa 0.42; 95% CI 0.32 to 0.51) but independent data were collected on only 4 eligible cases. Self-reported use of conspicuity aids was higher amongst cases and controls in this study than that observed for cyclists in the study area during the recruitment period (23%; 95% CI 22% to 24%). Discussion The results of this study show a non-significant increase in the odds of a crash for users compared to non-users of conspicuity aids whilst cycling. This association was increased after adjustment for confounders but most models generated to adjust for confounding remained insignificant. No reduction in crash risk could be demonstrated. This is not consistent with the large body of evidence suggesting that conspicuity aids increase the distances from which wearers can be detected and recognised by drivers in a variety of settings. There was evidence that cases were cycling along routes with greater exposure to traffic danger than controls although there were many participants with missing data for this variable potentially introducing a further source of bias. The route risk estimates did not vary significantly between conspicuity aid users and non-users. Residual confounding may have occurred if conspicuity aid users were taking more risks when encountering similar traffic conditions to non-users. This could not be measured but may go some way to explaining these results. If cyclists over-estimate the likely effect of their conspicuity aid use this could result in over compensation and a net increase in crash risk. Adjustment for route risk may have introduced bias by the loss of some participants from the analysis or by acting as a positive suppressor variable increasing the influence of uncontrolled confounding if conspicuity aid use were leading to risky riding over and above the objective risk arising from differing road and traffic conditions. The association between the odds of crash and travelling on roads with higher incidences of previous cycle crashes and fewer cyclists provides support for the “safety in numbers” effect reported in other studies. Differential selection and misclassification biases may also have resulted in over representation of conspicuity aid users amongst cases compared to controls. Social expectation from involvement in a collision crash may have resulted in cases who were not using conspicuity aids being less likely to participate than controls who were non-users. For similar reasons cases may have been more inclined to over-estimate their conspicuity aid use than controls.

Whilst the training of healthcare staff is seen as a key element to the prevention and management of violence and aggression, questions remain as to the effectiveness of these programmes in preparing staff to apply this to clinical practice. To date there is a relative paucity of well-designed studies into the effectiveness of the training to prevent and manage violence and aggression in healthcare settings. Within this context a study was conceived to examine the effectiveness of two aggression management training programmes in preparing staff for clinical practice. In order to provide a meaningful and evidence-based evaluation of the two programmes, Pawson and Tilley's Realistic Evaluation model was adopted for use in this study. In keeping with the chosen methodology, data was collected using a combination of methods including surveys, semi-structured interviews, and participant observation of training. A total of 64 participants were eligible for inclusion in the study; which ran over the course of a calendar year. The research highlighted that training should have relevance to the staff group undergoing instruction. That training should be conducted wherever possible in staff groups, tackling real problems, with participants reflecting and learning from their experience and from each other. It should also provide measures of competency that describe both workplace and organisational outcomes and describe the requirements of assessment. That training should be engaging and integrate decision-making, planning, organization and skill building and cover a range of interventions. Most importantly, was the need to help staff transfer what they had learnt as part of training to clinical practice. These factors are brought together in a model of training devised as part of this study called the PROMPTS Aggression Management Training Model ©. As the first study to apply realistic evaluation in aggression management research, it was a good fit, particularly given the growing emphasis on understanding how context influences evidence-based practice. The strengths and limitations of the approach are considered, including how to operationalize it. This approach provided a useful interpretive framework with which to make sense of the multiple factors that were simultaneously at play and being observed through various data sources, and for developing explanatory theory about aggression management training and its implementation in practice.

Clinicians working with women in forensic secure environments will be acutely aware of the diverse risks, complex treatment needs and unique responsivity issues found in this multifaceted marginal group. Women make up 5% of the prison population and approx 20% of the secure forensic psychiatric population (approx 4,500 and 1,085 women respectively). What animates the studies of women is not so much numbers of offenders but the particular circumstances of the women and girls “behind” the numbers. There is a common perception that women make up such a small number of the criminal justice service (CJS) population that devising gender sensitive environments and interventions is unnecessary. However studies of patients detained in high and medium security have identified significant gender differences. Women are more likely to commit minor offenses, be diagnosed with a personality disorder, present with self injurious behavior and have suffered childhood victimization. Thus, women and girls who are caught up in the justice system enter it as a result of circumstances distinctly different from those of men. Up until recently the needs of women were inadequately met in services centered on the needs of men and it is only relatively recently that the need to address these glaring differences has been thrashed out in the public arena. Following a number of high profile reviews and reports mixed sex wards have been become a exceptional, strip searches of women in prison have been abolished and large numbers of women have been reviewed and stepped down to lower levels of security. A less well researched area of women’s secure care centers on the profound impact of adjusting to a new environment which involves coping with severance of social support networks.

<p> The purpose of this project is to create a fun and educational nutrition program for middle school students including sixth, seventh and eighth grade. The nutrition program strives to increase understanding about the benefits of nutrition to encourage middle school students to consume more fruits and vegetables and to decrease the rate of childhood obesity. Based on current research, a curriculum was developed to include lecture, discussion, and activity components to guide in: creating cafeteria posters, responsible use of social media, and empowering other students by sharing their knowledge. Pre- and post-program questionnaires were also included. A committee of nutrition professionals and educators reviewed the curriculum and revisions were made based on their feedback. The program was not pilot-tested for the purposes of this project, but it is encouraged to do so prior to implementation.</p>

<p> Adolescent pregnancy and parenthood have been identified as national public health problems and are topics of intense debate in the United States because of their impact on maternal and child health and on the social and economic well-being of the nation. While many types of parenting programs are available to the adolescent mother, not one approach has emerged as the most effective to decrease subsequent pregnancies and to improve mother and child health. Using Husserl's Phenomenology as a philosophical underpinning, what it means to be a pregnant adolescent living in a group home was explored. Data were collected from volunteers who had lived in two group homes in a suburban county in the Mid-Atlantic area of the U.S. In-depth, one-on-one interviews using a semi-structured guide were completed with eight participants. Giorgi's steps for analysis of the verbatim transcripts were used to develop <i> essences and the essential structure</i> about the phenomenon understudy. The participants' ages when they lived in the group home ranged from 13-17 years; the time they lived in the group home was between one to two years and some adolescents, after delivery, lived in the group home from six months to two years. Three themes emerged, each with subthemes, describing the participants' experiences: <i>The environment with its rules and structure was experienced as either supportive or not in day-to-day living; Balancing adolescent expectations and needs impacted pregnancy and parenting; and Defining motherhood focused on the basics and was influenced by the participants' own mothering</i>. The study's fmdings were compared and contrasted with well-known nursing, individual development, and parenting theories and relevant research findings. Nurses who care for adolescents throughout their pregnancy and the postpartum period are uniquely positioned to influence their development as mothers. </p>

Aim: To assess the historical significance of the first Cholera epidemic in Britain. Part One. The Soil: describes the political, social and medical background to the 1831-2 period. Some subjects previously neglected by medical historians are dicussed. - Improvement Commissions as Public Health bodies; the population surge at the end of the 18th century and whether due primarily to economic or medical factors; the part played by 18th century doctors in developing the "sanitary idea". Part Two. The Seed: Cholera had every characteristic most calculated to strike terror into a community. The Press for the first time played an important part in keeping the public informed about the disease. A great contagion/anticontagion controversy arose; a victory for anticontagionism gave strong medical support to social reformers. Part Three. The Growth: The Cholera visitation led to: Formation of Central Boards of Health - a laissez-faire Government forced to accept public health as a proper sphere for State action. Formation throughout the country of Local Boards of Health - the first nation-wide attempt at community health control. Two Local Boards are described for the first time, both accounts based on original, unpublished records. The general characteristics, problems and effectiveness of Local Boards are discussed, and their influence on subsequent rise of modern public health. Part Four. The Fruit: The chance occurrence of such a disease at such a time in our socio-medical history proves a blessing in disguise: it leads to a start of modern public health administration; to Medicine gaining in knowledge, hospitals and prestige; and to the addition of fear, self-interest and medlcal support to the growing demand for social reform.

<p> Little is known about the impact of ethnic microaggressions (MA) on stress reactivity. The purpose of the current study was to examine how the frequency with which college students (<i>n</i> = 109) experience MA and their reactions to them relate to a biomarker of stress (i.e. salivary cortisol). Participants were exposed to the Trier Social Stress Test (TSST) and answered questions about the frequency of experiences of ethnic MA and their reaction to them (e.g. getting upset). Cortisol reactivity, cortisol recovery, and Area Under the Curve (AUC) were also assessed. Results of hierarchical regressions suggest that negative MA reactivity (i.e. getting upset) was associated with faster recovery and smaller AUC. Additionally, having high frequency of MA and high MA reactivity was associated with a blunted cortisol reactivity. Blunted cortisol responses may have negative health implications, as they have been associated to substance use, smoking, and obesity.</p><p>

<p> Background: Low- and middle-income countries have been experiencing unprecedented rates of urbanization. Rapid urbanization has attributed to an upsurge in non-communicable diseases, such as diabetes, cardiovascular diseases, and cancers in these countries. Most low- and middle-income countries are also still struggling to control communicable diseases such as HIV/AIDS, tuberculosis, and malaria. This phenomenon, described as the double burden of disease, places greater strains on urban health systems and vulnerable urban populations, such as slum dwellers, who are likely to bear the brunt of any negative health outcomes. Given the potential impacts of urbanization and quality of health services on poverty and disease in the urban poor, there is urgent need to study urban health systems and the ways in which services can be made more available, accessible, and acceptable to socioeconomically disadvantaged and culturally/ethnically diverse populations. </p><p> Objectives: This dissertation is a case study that investigated the community-defined health system for Korogocho slum residents in Nairobi, Kenya. Specifically, the purpose of the research study was to (1) determine the readiness of health workers to provide HIV- and diabetes-related services, (2) define the components of the health system as perceived by Korogocho residents; that is, determine the community-defined health system, (3) assess the factors that affect health service utilization with respect to HIV/AIDS and diabetes prevention, care, and treatment, and (4) make recommendations for improving the availability, accessibility, and acceptability of health services for Korogocho residents. </p><p> Methods: The case study research employed both quantitative and qualitative methods. Three complementary peer-review quality manuscripts were developed. Manuscript 1 presents results from one of the first assessments of health provider readiness to provide HIV/AIDS- and diabetes-related services using data from the Demographic and Health Survey&rsquo;s Kenya Service Provision Assessment. A cross-sectional quantitative study was conducted. Readiness was defined as health workers having the training to provide the minimum HIV/AIDS services as prescribed by key government policies. Data analysis was conducted using STATA version 13 to assess the readiness of health workers in terms of a weighted proportion of providers from facility levels 2-4 who were trained in essential HIV/AIDS- and diabetes-related services according to Kenya&rsquo;s national guidelines. Manuscript 2 details the results of a qualitative inquiry to understand the community-defined health system and identify factors that influence Korogocho residents&rsquo; health utilization behavior, especially in relation to HIV/AIDS and diabetes services. Manuscript 3 utilized a qualitative assessment to determine the role of informal health providers (those who have not received a Western biomedical model of medical training) in health service delivery to the Korogocho community. In both Manuscripts 2 and 3, semi-structured interviews were conducted with community members and informal health providers, respectively. Qualitative sampling was conducted with the purpose of generating a conceptual model of the urban health system for slum residents. Analysis of semi-structured qualitative interviews with community members and informal health providers in Manuscripts 2 and 3 was completed through an iterative process using NVivo 11 for Mac. </p><p> Results: The results of this research demonstrate the complexity of urban health systems. Korogocho residents utilize health services from a variety of facilities and providers from both the formal and informal sectors. Their health utilization behavior is primarily influenced by the availability, accessibility, and acceptability of health services, health facilities, and health providers. Informal health providers play a critical role in terms of expanding the availability and accessibility of health services to Korogocho residents. The results of this case study also reveal that training levels of health providers in Nairobi for the delivery of HIV- and diabetes-related services are low. On average, 12% of health workers interviewed in the 2010 Kenya service provision assessment reported having training in the previous 2 years in the full complement of essential HIV-related services as prescribed by Kenyan Government policies. There were similar low proportions of training for the provision of diabetes-related services among the three health worker cadres included in this analysis of the 2010 Kenya service provision assessment. Moreover, the community&rsquo;s perceptions of the availability and accessibility of diabetes services lagged behind HIV services.</p><p> Conclusions: The results of this research reveal key information that can impact the health systems strengthening agenda, particularly for improving the availability and accessibility of health services to the urban poor. It is also clear from this research that there is an urgent need to scale up the training of health providers to handle the current double burden of disease. Further, among socioeconomically disadvantaged populations, such as urban slums, the intentional incorporation of informal providers into the health system is a key step towards ensuring that much needed health services reach the urban poor.</p>

<p> The study investigated the relationship of physical activity (domain, frequency, amount, and intensity) on mental health (depression, stress, and anxiety) in the general population. Two hundred and fifty-three individuals eighteen or older completed either an online or paper survey for the study. Pearson Correlation, T-tests, and multiple regression were used in the data analysis. Results indicated vigorous activity correlated negatively with stress (<i>r</i> = -.16 <i>p</i> &lt; .01) and anxiety, (<i> r</i> = -.15 <i>p</i> &lt; .01). Amount of activity correlated negatively with anxiety, <i>r</i> = -.15 <i>p</i> &lt; .05. Leisure time activity, frequency of activity, and amount of activity were significant predictors of stress among females, R² = .07, <i> p</i> &lt; .05 and anxiety among males, R² = .09, <i> p</i> &lt; .05 (vigorous for men and moderate for female). Males were found to participate in significantly more vigorous leisure activity than females, <i>t</i> = 2.50, <i>p</i> &lt; .01. Given the limited research on factors of physical activity, results of the study offer useful information for future research into the complexities of physical activity and its effects on mental health.</p>
