This paper describes 15 years of research on homelessness using a modified ESID approach. The article summarizes the results of several needs assessment studies; describes the development and evolution of alternative treatment models to assist homeless individuals with severe mental illness; summarizes results of three outcome evaluation studies; and discusses issues of treatment implementation, treatment diffusion, and dissemination.  相似文献

The likely impact of applying the General Agreement on Trade in Services (GATS) to higher education are examined. GATS aims to “open up” services to competition: no preference can be shown to national or government providers. The consequences for teaching are likely to be that private companies, with degree-awarding powers, would be eligible for the same subsidies as public providers. Appealing to the inadequate recently introduced “benchmark” statements as proof of quality, they would provide a “bare bones” service at lower cost. Public subsidies would go: education being reduced to that minimum which could be packaged in terms of verifiable “learning outcomes”. The loss of “higher” aspirations, such education of critically-minded citizens of a democratic and civilised society would impoverish the university’s research culture which demands honesty and openness to public scrutiny. Most university research is substantially supported by public subsidy. Under GATS discipline, commercial providers of research services could be entitled to similar public subsidies. Publicly funded fundamental research would fade, leaving university research totally dependent for funds upon the good will of industry and commerce. Present problems, such as the suppression of unwelcome results and the use of questionable results to manipulate public opinion, would considerably increase. The public would lose a prime source of trustworthy knowledge, needed in political discourse, legal disputation, consumer protection and in many other contexts.  相似文献

The ethical implications of the new research paradigm   总被引:1,自引:0,他引:1  
Research is now an increasingly heterogeneous activity involving an expanded range of new actors and stake-holders and employing an eclectic range of epistemologies and methodologies. The emergence of these new research paradigms — and, in particular, of so-called ‘Mode 2’ knowledge production that is highly contextualised and socially distributed — raises new and challenging ethical issues and also important questions about the autonomy of science and the social responsibilities of scientists.  相似文献

Two experiments are reported examining the relationship between lexical and syntactic processing during language comprehension, combining techniques common to the on-line study of syntactic ambiguity resolution with priming techniques common to the study of lexical processing. By manipulating grammatical properties of lexical primes, we explore how lexically based knowledge is activated and guides combinatory sentence processing. Particularly, we find that nouns (like verbs, see Trueswell & Kim, 1998) can activate detailed lexically specific syntactic information and that these representations guide the resolution of relevant syntactic ambiguities pertaining to verb argument structure. These findings suggest that certain principles of knowledge representation common to theories of lexical knowledge—such as overlapping and distributed representations—also characterize grammatical knowledge. Additionally, observations from an auditory comprehension study suggest similar conclusions about the lexical nature of parsing in spoken language comprehension. They also suggest that thematic role and syntactic preferences are activated during word recognition and that both influence combinatory processing.  相似文献

This study reports two experiments assessing the spelling performance of French first graders after 3 months and after 9 months of literacy instruction. The participants were asked to spell high and low frequency irregular words (Experiment 1) and pseudowords, some of which had lexical neighbours (Experiment 2). The lexical database which children had been exposed to was strictly controlled. Both a frequency effect in word spelling accuracy and an analogy effect in pseudoword spelling were obtained after only 3 months of reading instruction. The results suggest that children establish specific orthographic knowledge from the very beginning of literacy acquisition.  相似文献

Suppose that you are evaluating two delivery companies. Your investigation shows that Company B has a better on-time rate for small packages and also for large packages. Despite Company B's performance, however, Company A has a better overall on-time rate. This situation exemplifies Simpson's Paradox, in which the judged relationship between two variables (e.g., company and performance) differs depending on whether that relationship is viewed within subcategories of a third variable (e.g., package size) or in the aggregate. A normative analysis is presented arguing that the reasonableness of using the third variable depends upon the sample size as well as the separation between and variability within categories. To test subjects' abilities to behave appropriately in Simpson's Paradox situations, we examined responses to variations in these factors in five studies. Results showed that subjects had little or no sensitivity to differing stimulus set sizes. Also, subjects were sensitive to relationship strength and the variability within and between groups, and in nonnormative ways. Subjects' judgment behavior is related to a broader perspective concerning selection among multiple available levels of analysis based on a consideration of argument strength.  相似文献

The processes of urban regeneration of long‐disinvested inner‐city neighbourhoods today happening in many European cities sometimes dramatically transform residents' traditional uses of their public places. Focusing on a neighbourhood renowned for its traditional public place sociability – Mouraria, in Lisbon – this study explored the psychosocial processes that may shape the maintenance of that sociability in the face of increasing social diversification and small‐scale gentrification brought about by a mixed/bottom‐up regeneration plan. A questionnaire survey (n = 201) with two types of residents (“traditional residents” and “new gentrifiers”) indicated that: (a) both types report using Mouraria's public places for socializing, although traditional residents do so to a greater degree; (b) perceived cultural continuity of the neighbourhood is positively related to public place sociability for both groups; and (c) this relationship is mediated by both place identification and place knowledge; but (d) it is not moderated by type of resident. By implication, we argue that regenerated inner‐city neighbourhoods may remain as places of lively public sociability and companionship if residents are able to forge and/or retain a sense of identification with, and intimate knowledge of, the neighbourhood, and view it as maintaining continuity with the past.  相似文献

Kind representations, concepts like table, triangle, dog, and planet, underlie generic language. Here, we investigate the formal structure of kind representations—the structure that distinguishes kind representations from other types of representations. The present studies confirm that participants distinguish generic-supporting properties of individuals (e.g., this watch is made of steel) and accidental properties (e.g., this watch is on the nightstand). Furthermore, work dating back to Aristotle establishes that only some generic-supporting properties bear a principled connection to the kind, that is, are true of an individual by virtue of its being a member of a specific kind (e.g., telling time for a watch). The present studies tested the hypothesis that principled connections are part of the formal structure of kind representations. Specifically, they tested whether they structure a newly learned kind representation. Experiment 1 found that introducing a property of a newly encountered novel kind in any one of four linguistic frames that provide evidence that a property has a principled connection to a kind (e.g., “It has fur because it is a blick”) led participants to infer a different conceptual consequence of principled connections (i.e., “There is something wrong with this blick, which does not have fur”) for which they had no direct evidence. Two introduction frames that provided no evidence for principled connections (e.g., “Almost all blicks have fur”) did not generate the same consequence. Experiment 2 found that all of the targeted properties were generic licensing, irrespective of the introduction frame. That the distinction between properties that bear principled connections to their kinds, and merely generic-supporting properties structures novel kind representations, provides strong evidence that this distinction is part of the formal structure of kind representations.  相似文献

Contemporary models for athlete development and performance preparation in sport have advocated a role re-conceptualisation for coaches grounded as learning environment designers. Within this re-conceptualisation, expert practitioners are encouraged to draw upon their experiential knowledge to design representative and meaningful learning activities that place the performer-environment interaction at its core. However, we propose that, currently, a critical source of experiential knowledge is often overlooked within the process of learning design – that of performers. Specifically, practitioner-performer interactions could enrich the design of learning environments by promoting the utilisation of soliciting affordances and encouraging the psychological engagement of performers. This paper introduces the concept of representative co-design – a notion which builds on existing research by framing how the insights and experiences of performers can be negotiated within the design of practice tasks that seek to faithfully simulate interacting constraints of competition to enrich learning environments. We frame the notion of representative co-design, and contend its importance within more contemporary athlete development and performance preparation models, at two levels: (i) that of enriching physical education curricula to develop thought provoking, ‘intelligent’ child/adolescent learners, and (ii) that of enriching contemporary athlete preparation models in high-performance sport to enhance learning and engagement, and to develop ‘next generation’ coaches within current athletes. To bring this conceptualisation to life, we present two exemplars demonstrating the notion of representative co-design, while concurrently highlighting areas for future research.  相似文献
