Social workers are better equipped to understand the need to incorporate geographical aspects pertaining to their clients’ lives as part of their practice, given the significant influence these factors have on client well-being. Geographic Information Systems (GIS) technology is a useful tool for administrators and planners to make informed decisions regarding human service programs including examining program outcomes and impact as well as streamlining program implementation. This article synthesizes the literature to date on GIS in health and human services with examples of real world applications. 相似文献
This paper is the result of our increasing interest in the experience of illness in families and the concomitant reflections on how best to therapeutically support these families through this process. This interest led us to reflect on the nuanced way in which language establishes a play with the experience of illness, a play that can amplify or reduce its effects. Such an interplay in turn led us to consider the valuable role that family therapists have in helping families and treating practitioners to create a safe space for conversation about illness. Further questions are also explored in relation to whether there is a role for family therapists in facilitating the interface between our clinical practice with clients and the wider treating medical community. And, if so, what shape would such an interface take? Considerations at this level would include the anticipation of psychological reactions to diagnosis of chronic and life‐threatening illnesses, in particular the importance of ‘normalisation’ of the psychological reactions to such chronic and/or life threatening diagnoses; the complex dynamics emerging from the interface between the effects of illness in the subjectivity of the ill person and the grief experienced by the other family members; different family members’ narratives of the illness; relevant community contexts; and, lastly, ways to help the family members and/or the ill person navigate the medical system including the use of second opinions, cyberspace information, and other systems in their ecology, such as the spiritual dimension. Some aspects of children's narratives of illness are also identified. The paper has been organised around the dialogue that the authors had around one of their clinical cases. 相似文献
Over the past five years the Artificial Intelligence Center at SRI has been developing a new technology to address the problem of automated information management within real- world contexts. The result of this work is a body of techniques for automated reasoning from evidence that we call evidential reasoning. The techniques are based upon the mathematics of belief functions developed by Dempster and Shafer and have been successfully applied to a variety of problems including computer vision, multisensor integration, and intelligence analysis.
We have developed both a formal basis and a framework for implementating automated reasoning systems based upon these techniques. Both the formal and practical approach can be divided into four parts: (1) specifying a set of distinct propositional spaces, (2) specifying the interrelationships among these spaces, (3) representing bodies of evidence as belief distributions, and (4) establishing paths of the bodies for evidence to move through these spaces by means of evidential operations, eventually converging on spaces where the target questions can be answered. These steps specify a means for arguing from multiple bodies of evidence toward a particular (probabilistic) conclusion. Argument construction is the process by which such evidential analyses are constructed and is the analogue of constructing proof trees in a logical context.
This technology features the ability to reason from uncertain, incomplete, and occasionally inaccurate information based upon seven evidential operations: fusion, discounting, translation, projection, summarization, interpretation, and gisting. These operation are theoretically sound but have intuitive appeal as well.
In implementing this formal approach, we have found that evidential arguments can be represented as graphs. To support the construction, modification, and interrogation of evidential arguments, we have developed Gister. Gister provides an interactive, menu-driven, graphical interface that allows these graphical structures to be easily manipulated.
Our goal is to provide effective automated aids to domain experts for argument construction. Gister represents our first attempt at such an aid. 相似文献
Relative to White families, Black families have been described as relying on extended social networks to compensate for other social and economic disadvantages. The presence or absence of supportive social networks should be especially relevant to young couples entering marriage, but to date there has been little effort to describe the social networks of comparable Black and White newlyweds. The current study addressed this gap by drawing on interviews with 57 first‐married newlyweds from low‐income communities to compare the composition and structure of Black and White couples' duocentric social networks. The results indicated that low‐income Black couples entered marriage at a social disadvantage relative to White couples, with more family relationships but fewer positive relationships and fewer sources of emotional support (for wives), fewer connections to married individuals, and fewer shared relationships between spouses. Black couples' relative social disadvantages persisted even when various economic and demographic variables were controlled. 相似文献
Although the organizational structures and operating procedures of state substance abuse prevention systems vary substantially across states, there is scant empirical research regarding approaches for rigorous assessment of system attributes and which attributes are most conducive to overall effectiveness. As one component of the national cross-site evaluation of the SPF State Incentive Grant Program (SPF SIG), an instrument was developed to assess state substance abuse prevention system infrastructure in order to measure infrastructure change and examine the role of state infrastructure in achieving prevention-related outcomes. In this paper we describe the development of this instrument and summarize findings from its baseline administration. As expected, states and territories were found to vary substantially with respect seven key characteristics, or domains, of state prevention infrastructure. Across the six domains that were assessed using numeric ratings, states scored highest on data systems and lowest on strategic planning. Positive intercorrelations were observed among these domains, indicating that states with high capacity on one domain generally have relatively high capacity on other domains as well. The findings also suggest that state prevention infrastructure development is linked to both funding from state government and the presence of a state interagency coordinating body with decision-making authority. The methodology and baseline findings presented will be used to inform the ongoing national cross-site evaluation of the SPF SIG and may provide useful information to guide further research on state substance abuse prevention infrastructure. 相似文献
The Brazilian organic food sector has experienced important growth during the last two decades. Brazilian smallholders, however, are facing huge challenges to enter and benefit from this growth in a sustainable way. Combining the lens of New Institutional Economics and socio-anthropology, we analyze six experiences of Brazilian smallholders who converted to organics in the 1990s’. Three different food systems are featured in this analysis: an alternative food system, which is strongly interwoven with the Brazilian Agro-ecological movement and two commercial food procurement systems oriented towards domestic and an export markets driven mainly by supermarket chains. The analytical focus was on 1) the governance of these food systems, 2) the constraints farmers are facing within these food systems and, 3) the benefits that they can expect from market inclusion. We highlighted the roles that NGOs, Faith-based organizations and public-related agencies play in supporting the inclusion of smallholders into all three food systems. We confirmed the arguments in support of pursuing the agro-ecological development based model in Brazil, but underlined that there is a critical lack of support for farmers included in the commercial market-oriented food systems. Such a lack is even more critical as the food systems driven by expanding supermarket chains are characterized by strong asymmetric power relations at the expense of smallholders. Considering the reluctance of NGOs and Faith-based organizations to support these farmers, we call for efforts to be made to provide a policy framework to enable public-related entities to secure sustainable inclusion into these systems and exit strategies for those experiencing exclusion from these highly competitive food systems. 相似文献
Working with survivors of trauma is mostly challenging, exhausting, long‐term and often ‘messy’, when interventions that ‘should’ work, don't, or the unexpected arises. Nevertheless, explanations that speak to recovery from trauma more and more rely on neurobiological concepts to account for any positive change. Combining the family systems approach of Murray Bowen and recent research on the brain and trauma, post trauma symptoms are viewed as part of the ‘family emotional process’ even when traumatic events have emanated from outside the family system itself. Variations in responses to trauma, including dissociation and self‐harm are discussed in relation to chronic anxiety and ‘differentiation of self’. 相似文献
