Racial-ethnic disparities in static levels of health are well documented. Less is known about racial-ethnic differences in age trajectories of health. The few studies on this topic have examined only single health outcomes and focused on black-white disparities. This study extends prior research by using a life course perspective, panel data from the Health and Retirement Study, and multilevel growth curve models to investigate racial-ethnic differences in the trajectories of serious conditions and functional limitations among blacks, Mexican Americans, and whites. We test three hypotheses on the nature of racial-ethnic disparities in health across the life course (aging-as-leveler, persistent inequality, and cumulative disadvantage). Results controlling for mortality selection reveal that support for the hypotheses varies by health outcome, racial-ethnic group, and life stage. Controlling for childhood socioeconomic status, adult social and economic resources, and health behaviors reduces but does not eliminate racial-ethnic disparities in health trajectories.  相似文献

The immune system, in cooperation with neuroendocrine functions, defends from cancer and infections mainly by the activity of blood natural killer (NK) cells. Blood NK activity may be influenced by the type of employment since work is the central part of life; moreover, job stress is a situation affecting both neuroendocrine and immune systems. This study examines anxiety (by STAI 1 and 2), job strain (by the Karasek's JCQ) and blood NK activity (by an in vitro radio-isotopic method) of 134 male workers. These men, over 38 years old with stable employment, were working in factories, in construction yards, in offices, as hospital attendants or as self-employed craftsmen. Workers in factories and in construction yards, with high job strain, showed lower NK activity, while office employees, with low job demand, and craftsmen with low anxiety and elevated decision latitude, showed higher NK activity; the level of NK activity of the hospital attendants was between the other groups. In conclusion, this study confirms that the type of employment, related to job stress, affects blood NK activity. Moreover, blood NK activity may be used in the bio-monitoring of workers at high risk.  相似文献

This paper shows that if a very small, exogenously given probability of terminating the exchange is introduced in an elementary investment game, more reciprocators will choose the defection strategy. Everything happens as if they “hide behind probabilities” in order to break the trust relationship. Investors do not alter their behavior in a significant way, at least not for a very small external risk. Financial assets all come with a predetermined and contractual probability that by the time when the buyer has to receive the reward for his investment, “bad luck” might have brought the asset value down to zero. In the light of the experimental findings, such trades would not provide a favorable environment for building trust.  相似文献

With the ever-increasing growth in the aging population, the need for care providers will also continue to rise. Many of these caregivers will provide informal care to family members and friends at a price to their own physical, psychological, and social well-being. This article examines the phenomenon of caregiving and provides a review of the biological, psychological, and social impacts of caregiving to care providers. George Engel’s biopsychosocial model is explored to examine the biological, psychological, and social factors that can affect a caregiver’s health and well-being. This article further explores social work practice implications and strategies for future intervention to reduce caregiver burnout and aid in their self-preservation.  相似文献

This paper considers the value of Hymesian ethnopoetics as a means of analysing everyday narrative in conditions of mobility and change. The paper offers an account of the development of ethnopoetics as a means to make visible and valorize narrative in the Native American oral tradition, and as a method of revealing culturally specific relations of form and meaning. Hymes’ ethnopoetic approach viewed narrative structure as a reflection of a cultural tradition of meaning‐making. Hymes’ analysis proposed that traditional narrative was a culturally shaped way of speaking, and analysis of narrative structure could reveal and recreate culture. His orientation rested on an assumption that the culture of a group was more or less stable and fixed. This paper adopts an approach to analysis based on ethnopoetics, representing everyday narrative dramatically, organized not only as lines and verses, but also as scenes and acts. Representation in scenes and acts makes visible the dynamic nature of the narrative. The paper asks whether Hymes’ ground‐breaking work on ethnopoetics still has currency and purchase in 21st‐century conditions of mobility, change, and unpredictability. Analysis of everyday narrative in a city market concludes that, notwithstanding the complexity of notions of ‘culture’ and ‘language’ in such conditions, ethnopoetics can be productively applied to everyday contexts for the analysis of narrative.  相似文献

The proliferation of nongovernmental organizations (NGOs) since the 1970s has generated a wealth of research as to the causes and implications of the rise of this sector. Public awareness of NGOs and their activities has grown as well, at least in part due to increased media coverage of the organizations and the situations to which they respond. Although NGOs are not new to global polity, media attention to them as a sector only really began to take off in the 1990s. Using quantitative and qualitative analysis of two international newspapers from 1985-2010, this study explores the legitimation process of NGOs and examines the role of categorization and labeling in this process. The results show that the establishment of a distinct label in the media served to propel cognitive recognition of NGOs, and that media coverage reflects changes in cognitive legitimacy over time.  相似文献

This paper explores the role and significance of independent inventors within the national innovation system. By using a case study based on interviews with 22 independent inventors, it examines the types of social capital facilitating independent inventors' access to relevant knowledge and information. The findings show that, in line with their marginalization in the national innovation system, independent inventors have very limited access to the services and assistance of supportive organizations of the national innovation system. They primarily rely on the social capital residing in civil society organizations as well as the social capital of their family and friends. Professional and interdisciplinary linkages can thus be regarded as their weak point hindering their access to relevant knowledge and information.  相似文献

The aim of this study is to provide cross-cultural empirical support that endorses the scientific nature of Quality of Life (QoL), which a review of definitions reveals as a nomothetic and multidimensional concept (personal and environmental circumstances), made up of a set of subjective and objective indicators. Although this is commonly accepted, many instruments and authors reduce it to subjective and personal conditions. Bearing in mind the aim described, multi-group Structural Equation Modelling analysis was applied to two representative samples made up of 1217 participants aged over 60 from Mexico and Spain, recruited both at random (through the random route procedure), who completed the CUBRECAVI (Brief Questionnaire of Quality of Life). In this model two third-order latent variables are considered for QoL: personal and external factors, both made up of objective and subjective indicators. As predicted, the results permit us to state that the structural model is invariant across the two countries—that is, although the QoL construct has the same structure in the two countries, the importance of the indicators (factor loadings) and the relationships between them are not equivalent.  相似文献

Abstract

Decolonisation aims to deconstruct the hegemonic traditional Western academic practices and values that oppress Indigenous peoples. Decolonising research methodologies is a relatively new practice in disability research in colonised nations. This paper details the Indigenous community-controlled research methodology that underpinned a disability research project with the Anangu and Yarnangu of Central Australia, ‘Walykumunu Nyinaratjaku: To Live a Good Life’. The project aimed to identify and explore how to support Indigenous people with a disability in the Ngaanyatjarra Pitjantjatjara Yankunytjatjara (NPY) Lands to live a good life. The research was structured on a decolonising methodology to situate the control and governance of the research with the Indigenous peoples. Our experience could assist other disability researchers working with Indigenous peoples in remote communities.  相似文献
