Health centres established in Xochimilco, Mexico during the 1930s and 1940s represent a larger shift in the national health agenda from training medical students in rural health to addressing the specific health challenges of rural communities. While the 1935 centre offered urban students practical experience in rural environments, it did not adequately address the area's health problems. In contrast, the 1947 centre utilised improved community exchanges to enhance the region's health and sanitation. This decade of transformation resulted from a network of politicians, international organisations, and health professionals who helped to establish broader community‐based public health programmes in rural Mexico.  相似文献

The treatment of youthful offenders in correctional settings presents psychologists with a range of challenging ethical concerns. The inherent discord between psychologically based goals and correctional objectives yields a complicated ethical landscape for clinicians. These concerns can be partially addressed through the APA's revised Ethical Principles of Psychologists and Code of Conduct (2010) and field-specific practice guidelines but also require extensive further guidance to ensure competent and ethical practice. This article analyzes current information about youthful offenders, outlines disparities in stakeholder goals, provides an overview of ethical considerations of treating youthful offenders in correctional settings, and offers recommendations for education and practice.  相似文献

工时制度是劳动效率、劳动者健康水平、社会经济发展水平等多种因素综合作用的结果。研究基于“适度性”的视角,对工作时间进行文献梳理发现,劳资双方的博弈贯穿于工时制度演变的漫长过程,工作时间的“过”与“不及”均会对劳动者及社会经济发展产生负面影响,适当缩短工作时间有益于劳动者的身心健康和提高劳动生产率。其他差异性因素如性别、职业差异、工作环境、社会福利增减等同样会影响适度工作时间的确定。对于过劳问题、缩短工时的程度、灵活工时制度的运用等方面尚需进一步深入研究。  相似文献

Over the past twenty years interest has grown in the concept of social capital in international and Australian public policy. We explore how social capital is understood as a concept and used in practice for guiding policy development and program delivery in South Australian public health programs. The empirical research compared policy makers’ and practitioners’ understandings of social capital and how theories about social capital and health inequality were translated into practice in three case study projects. It found that there are shifting discourses between social capital and related concepts, including community capacity building, and social inclusion/exclusion. Policy makers reported less use of the concept of social capital in favour of social inclusion/exclusion reflecting changing political and policy environments where terms come into favour and then go out of fashion. In this transition period the two terms are often used interchangeably although there are some conceptual points of difference.  相似文献

ABSTRACT

The commercial value of indigenous South African animal and plant resources can add significantly to the nation's socioeconomic development and contribute towards the achievement of the goals of the African Renaissance. However, very few of the country's many indigenous plants have been successfully commercialised. This article reviews the development phases of one success story: rooibos tea. Its development trajectory offers a useful lesson in the commercialisation of other South African indigenous animal and plant resources. Constraints that hindered the effective commercialisation of the beverage are highlighted, notably the initial over-reliance on a local market and the lack of coordinated broad marketing and quality assurance. These constraints were compounded by international trade restrictions imposed on South Africa prior to the 1994 transition to democracy. While the world moved forward, the rooibos tea sector lagged behind in the development of niche markets. It was only in the late 1990s when a seemingly perfect match between the health-giving properties of rooibos and consumer needs was achieved, thus creating a vibrant niche market for the tea. Since then, production and sales of rooibos tea have increased markedly. Adherence to national and international codes of good manufacturing practice, together with the recognition of the importance of fair trade principles regarding the participation of small-scale cooperatives, are becoming increasingly important parameters for product acceptance.  相似文献

Abstract

Recounts the author's professional life history in the context of his personal life story. Reflects on the ways in which history and autobiography combine to create life pathways that are experienced as individually chosen, yet historically determined. Recounts the author's family life, neighborhood experiences, early education in the Philadelphia public schools, and the impact of post-World War II government programs including the GI Bill and the establishment of United States Public Health Service fellowships. Considers the influence of African American writers and the civil rights movement, as well as women returning to school, the culture of medical schools and the influence of mentors in the formation of a professional identity. Recounts the discovery of the community mental health movement and the search for a social justice agenda that led to Community Psychology. Ultimately, the author views himself as an “insider/outsider,” whose personal and professional identity crosses traditional boundaries and welcomes paradoxical, narrative and qualitative approaches to research and practice.  相似文献

The election of the Conservative–Liberal coalition in May 2010 provides the opportunity to start to map out the record of the Labour governments between 1997 and 2010. This paper deals with the specific question how the Brown/Blair governments performed on public expenditures when compared to the records of UK Labour governments since 1945. Did the public expenditure record of the 1997 represent a departure from that of previous Labour governments? This is important to ascertain since there are strongly held beliefs that New Labour was not committed to Labour's historic commitments of income redistribution and universal benefits. The analysis that follows is constructed around five major public expenditure programmes that reflect Labour's priorities. These include total expenditure, expenditure on health, education, housing and social security.  相似文献

多氯联苯类污染物对人类健康的影响   总被引:2,自引:0,他引:2  
多氯联苯(PCBs)为一类广泛存在的环境污染物,在环境中的分解速度缓慢且可通过食物链富集.文中讨论了PCBs对人类健康的影响,阐述了人体暴露于PCBs污染可能存在致癌作用,影响内分泌和生殖系统,以及刺激皮肤等.但目前尚无充分证据表明环境中的PCBs污染与癌症和内分泌失调存在必然联系.  相似文献
