This article shows the influence of ethnicity (people born outside Sweden and in Sweden) and social class (socioeconomic class) on the distribution of diagnoses, consultation time and health care utilization in primary health care controlled for sex, age, marital status and educational level. The study was designed as a prospective primary health care utilization study during 7 consecutive weeks. Of a total of 439 adults who lived in the residential area, 290 were born in Sweden and 149 were born elsewhere. The data were analysed unmatched with logistic regression and Poisson regression in main effect models. People born outside Sweden received significantly more diagnoses per consultation than people born in Sweden. The strongest independent risk indicator for musculoskeletal disease was being born outside Sweden, with an estimated odds ratio (OR) of 5.01, 95% confidence interval (CI) = 2.70–8.72. Age over 44 was associated with increased odds for musculoskeletal disease. Respiratory disease, as an indicator of less serious disease, were significantly less common among people born outside Sweden (OR = 0.53, 95% CI = 0.33–0.87). Being born outside Sweden was a risk indicator for consultations longer than 30 minutes (OR = 3.03, 95% CI=1.18–7.43). There were no differences between people born in Sweden and those born elsewhere in health and utilization. Social class was not associated with any of the dependent variables.  相似文献

In times of shrinking resources within the social services, collaboration is being promoted as a more efficient way of meeting the needs of children and families. A study of a children's initiative collaborative developed to address the problems of children is reported. The authors present and use an evaluation framework which incorporated the dimensions of context, process, and outcomes of collaboration. The findings, based on the initial two years of collaborative effort, suggested the membership of the group and the process and structure governing the group's operations impacted the process and outcomes of the collaboration.  相似文献

This is an argument for the plausibility of comparative network analyses of power in American cities. In terms of structural analyses of community power and decision-making, traditional methods of obtaining network data have fostered and enervating gap between the substantive richness of case studies and the generalizability of comparative studies. The purpose here is to describe a practical method of gathering ersatz network data from interviews with a small number of strategically chosen informants so as to conduct comparative network analyses of community power. The ersatz network element zij is the extent to which two types of actors I and J are perceived by informants as having simultaneous control over community issues. Using data from interviews with informants in 51 American cities, the ersatz network data are shown to be efficient, reliable and substantively valid despite their low cost. The data are efficient in the sense that the proportion of sampling variance in an estimated network element declines exponentially with increase in the element's magnitude. The data are reliable in the sense that estimated structures are stable over issue and informant bias per se. The data are valid in the sense that they are consistent with previous community research; types of ersatz power structures are located in the 51 cities (a machine structure, an urban structure, a faction structure, and a class of reform government structures) and these types occur in cities with characteristics known to be associated with each type of power structure. I conclude with a summary and comments regarding future research; the selection of informants and the use of a computer program in which easily available characteristics of a community are the basis for predicting the type of power structure it most likely exhibited during the late 1960s.  相似文献

Objective. This article takes issue with the way that second‐generation immigrants have been traditionally defined. In most studies, respondents are considered to be “second generation” if they are born in the United States and if at least one of their parents was born outside the United States. This article considers whether the experiences and outcomes of those with one U.S.‐born parent and one foreign‐born parent (the “2.5 generation”) are different from those with no U.S.‐born parents (the “2.0 generation”) and those with two native‐born parents (the “third generation”). Methods. The article analyzes data from the March Current Population Survey (CPS) from 1999 to 2001. Results. The evidence indicates that the 2.5 generation is a numerically significant population, and that it varies from other groups in age structure, racial identification, educational attainment, and income. Conclusions. In studying the U.S.‐born children of immigrants, scholars should avoid lumping together the 2.5 generation with those who have no native‐born parents. The members of the 2.5 generation also should be treated as distinct from those born in the United States to two native‐born parents.  相似文献

ABSTRACT

In recent decades, restorative justice has gained considerable recognition worldwide and has become a prominent option for diverting juveniles away from the traditional criminal justice system as well as delivering fair and just outcomes in the justice process. This paper provides an overview of how the criminal justice system operates for juvenile offenders in the People’s Republic of China (hereafter, China). Based on a sophisticated literature review of recent Chinese academic journal articles on restorative justice for juveniles, the paper presents an analysis of the characteristics and operational procedures of current practices. Deficits and potential future developments pertaining to Chinese restorative practices for delinquents are also discussed.  相似文献

Since September 2010, a series of earthquakes have caused widespread social, financial and environmental devastation in Christchurch, New Zealand. Anecdotal evidence suggests that local Māori responded effectively to facilitate community recovery and resilience. However, the form, content and extent of that response has not been adequately recognised or documented. This qualitative research project, conducted in partnership with Te Rūnanga o Ngāi Tahu, has documented the way in which Māori cultural factors have facilitated disaster risk reduction and management in response to the earthquakes. This paper explores sets of understandings about marginalisation and inclusion within the narratives of 70 Māori community members who contributed to this research. Forms of marginalisation expressed in participants’ narratives include delayed linkages to the formal emergency management infrastructure, difficulties integrating Māori volunteers into the mainstream response as well as enduring barriers to Māori engagement within Civil Defence, illustrated in a lack of Māori representation as well as tikanga Māori within emergency planning. We argue that the knowledge, principles and practices embedded within Māori responses to the Christchurch earthquakes may be contextually relevant for national and regional policy development in the area of disaster risk management, response and recovery.  相似文献

Multidisciplinary intervention approaches are needed for meeting service needs for families in which substance abuse and mental health disorders may be interfering with child‐rearing. Experiences from the Starting Early Starting Smart (SESS) initiative, a 12‐site national collaborative investigation of integrating behavioural health services in early childhood and primary health care service settings for children aged 0–5 years and their families and caregivers, are described. This 4‐year applied research initiative was co‐funded by the Substance Abuse and Mental Health Services Administration of the US Department of Health and Human Services and Casey Family Programs, a private operating foundation. SESS, which was developed and implemented in 12 geographically and culturally diverse cities in the USA during 1997–2001, encouraged federal, state, and local public/private partnerships. Opportunities and challenges in using an inclusive, consensus‐based, stakeholder model to maximize study relevance and utility for researchers, practitioners, and fiscal sponsors are discussed, and lessons for multidisciplinary, multisite research collaborations are identified.  相似文献

We introduce the notion of a dice model as a framework for describing a class of probabilistic relations. We investigate the transitivity of the probabilistic relation generated by a dice model and prove that it is a special type of cycle-transitivity that is situated between moderate stochastic transitivity or product-transitivity on the one side, and ukasiewicz-transitivity on the other side. Finally, it is shown that any probabilistic relation with rational elements on a three-dimensional space of alternatives which possesses this particular type of cycle-transitivity, can be represented by a dice model. The same does not hold in higher dimensions.  相似文献
