This analysis uses canonical correlation techniques to explore client outcomes following psychosocial rehabilitation services in two rehabilitation areas: vocational and residential. At issue are the ways in which these two outcomes are affected by a series of eight client characteristics and service delivery features. The overarching question is the effectiveness of the program in establishing independence vocationally and residentially, and whether the same set of factors influences these two outcomes for persons with mental illness. Subjects were 212 ex-clients of a psychosocial rehabilitation agency who were working six months after leaving the program. The analysis derived two canonical functions both of which were significant. Canonical loadings and cross loadings indicated that client level of functioning and program tenure loaded most strongly with residential status on the first canonical variate while education loaded most strongly with salary on the second. These results support the notions that different predictors account for the variance associated with different outcomes following psychosocial rehabilitation. Discussion of the relevance of strong predictor variables highlights ways they can impact program design. Finally, the usefulness of canonical correlation in longitudinal program evaluation research is explored.  相似文献

A set of items from the General Social Survey for 1975 and 1977measuring alienation and fear of walking near one's home atnight, which were claimed by Gerbner et al. (1978a) to be relatedto heavy television watching, are reanalyzed with simultaneouscontrols for age, sex, race, income, education, hours workedper week outside the home, church attendance, membership involuntary associations, and population size. The effects oftelevision watching on responses to these items which were claimedby Gerbner et al. are largely absent in this analysis. Itemsin the same data set used by Gerbner et al., but not includedin their analysis are analyzed using the technique above, withresults that fail to support the contention of Gerbner and hisassociates. The implications of these findings for a cultivationtheory of television effects are discussed.  相似文献

Using recursive partitioning on thousands of enrollment Child and Adolescent Needs and Strengths (CANS) assessments, we identified characteristics of the most troubled children/youth requiring comprehensive interventions reflected by a count of total actionable items (TAI) from 129 possible CANS actionable treatment planning items. Samples included 2557 and 6982 children/youth from two separate large, multi-program, California-based mental health treatment agencies administering CANS routinely upon enrollment. In two separate random forest analyses, 20 top predictors were identified which indicated very high levels of clinical severity needing comprehensive, urgent intervention at each agency, with 13 out of the 20 predictors common to both agencies' populations. Agency-specific decision trees were constructed with the top 20 predictors to examine relationships between predictors, which further identified four predictors of need highly prioritized at both agencies: child's frustration management problems, recreation and leisure time activity challenges, poor response to consequences for aggressive behavior, and lack of optimism. Within these service populations, children with actionable need for intervention in these four areas had four to five times more TAI as compared to children without these areas identified. A handful of the CANS items assessed can indicate very high severity ratings for a service population, and localized use of recursive partitioning analysis based on TAI can identify these core problems for specific programs or across agencies, helping clinicians to understand patterns and priorities within populations served.  相似文献

The first part of this non-technical review of canonical analysis is concerned with the principle, the data requirements, the interpretation, the evaluation and the application in consumer research of canonical analysis. In this context, concepts as canonical correlation, weights, loadings and scores are explained. Their interrelationships are discussed. Then the characteristics of specific forms of canonical analysis: canonical correlation, canonical regression, redundancy analysis and partial canonical analysis are discussed. Their different application properties are emphasized. The last part consists of an application of canonical correlation analysis for brand positioning. Here the relationship with discriminant analysis is illustrated. Furthermore the usage of canonical analysis for optimal scaling purposes is illustrated for the same example.  相似文献

We propose a procedure for dividing a set of indivisible items between two players. We assume that each player’s preference over subsets of items is consistent with a strict ranking of the items, and that neither player has information about the other’s preferences. Our procedure ensures an envy-free division—each player receives a subset of items that it values more than the other player’s complementary subset—given that an envy-free division of “contested items,” which the players would choose at the same time, is possible. We show that the possibility of one player’s undercutting the other’s proposal, and implementing the reduced subset for himself or herself, makes the proposer “reasonable,” and generally leads to an envy-free division, even when the players rank items exactly the same. Although the undercut procedure is manipulable and its envy-free allocation may be Pareto-inferior, each player’s maximin strategy is to be truthful. Applications of the procedure are discussed briefly.  相似文献

In a study with 191 college students, canonical correlation analysis explored career search self‐efficacy and psychological distress (career search set) in relation to psychological resources and regulatory focus (career transition set), producing 2 significant canonical correlations. The 1st correlation dimension showed that decreased career search self‐efficacy and increased psychological distress had a moderate relationship with decreased psychological resources and minimal relationship with low promotion focus and high prevention focus. The 2nd dimension illustrated that the increase in anxiety and personal exploration efficacy were associated with increased readiness for the career transition and elevated prevention focus.  相似文献

Sexual Consent     
SUMMARY

What role can the criminal law play in the battle against child sexual abuse? Should sexual relations of, and with, persons under a certain age be criminalized regardless of the circumstances, even if they are consensual (“age of consent”, “minimum age”)? Where should such a minimum age-limit be fixed? Should there be a special, higher age-limit for particular conditions (e.g., “seduction”, “corruption”)? Should sexual contacts with minors within a relationship of authority be criminalized generally or just if authority is abused? Should criminal proceedings be instituted ex officio or upon complaint only? Should authorities be provided with a power of discretion or should they be obliged to prosecute and sentence in each case? In answering these important questions, it is highly beneficial to have a look across the borders to the solutions other countries have reached in this area.

This analysis will provide an overview on the criminal law governing the sexual behavior of, and with, children and adolescents in all European jurisdictions and in selected jurisdictions outside of Europe. It will show which categories of offenses exist and from which age onward young people can effectively consent to various kinds of sexual behavior and relations in the different countries. It turns out that all states in Europe and all of the studied jurisdictions overseas do have minimum age limits for sexual relations, do punish sexual relations with persons under a certain age. Nowhere is this age set lower than 12 years. In Europe in one-half of the jurisdictions, consensual sexual relations with 14-year-old adolescents are legal; in two-thirds with 15-year-olds; in a majority, this is also the case when the older partner has started the initiative (and also when the initiative contains an offer of remuneration). In nearly all jurisdictions, such relations are legal from the age of 16 onwards. Nearly all European jurisdictions set the same age limit in the criminal law for depicting sexual activity as for the sexual activity itself. Most states apply a higher age limit for contacts in relationships of authority. If the authority is not misused the age limit in most jurisdictions is set between 14 and 16; if it is misused between 16 and 18. Most states make no difference between heterosexual and homosexual relations.  相似文献

This paper focuses on the fair division of a set of indivisible items between two people when both have the same linear preference order on the items but may have different preferences over subsets of items. Surprisingly, divisions that are envy-free, Pareto-optimal, and ensure that the less well-off person does as well as possible (i.e., are equitable) can often be achieved. Preferences between subsets are assumed to satisfy axioms of qualitative probability without implying the existence of additive utilities, which is treated as a special case. Algorithms that render fair division practicable are proposed, and their vulnerability to strategic manipulation is investigated. Received: 18 May 1998/Accepted: 2 March 1999  相似文献

This paper explores the conceptualization and measurement of social position in relational data. It is argued that social positions are evidenced in the interactions among individuals, which are encoded in measured social relations. Given a set of measured relations the task is to reveal social positions which consist of groups of individuals wth similar patterns of relations. Methods based on two alternative approaches are discussed. The first set of approaches is based on structural equivalence, and locates groups of similar individuals based on the extent to which they share identical ties with identical others. A second set of approaches, here called general equivalences, locates groups of similar individuals based on their sharing of “types” of ties with “types” of others. Procedures based on these different approaches are described and applied to actual data and to a constructed example. Results suggest that these different approaches identify different kinds of social groups. It is argued that structural equivalence is an unsuitable basis for analysis of relational data if the goal is detection of social positions.  相似文献

Abstract

An examination of the contradiction between college student studies and national public opinion polls.

The evidence concerning the existence and magnitude of gender differences in sex-role attitudes is contradictory. A large number of studies, based primarily on college samples, have reported significant gender differences in the sex-role attitudes of young adults; males have been found to be more traditional than females. However, studies based on national samples including all age and educational groups have not found consistent gender differences. In order to investigate this contradiction, NORC General Social Survey was aggregated from the years 1974 through 1978 to create a data set that included a large number of young adults who were currently attending or who had recently attended college. Both age and education were found to be significant predictors of sex-role attitudes, but for most of the items examined gender differences were not found to be larger for young adults than for older adults. For both age groups larger gender differences were found in items pertaining to caring for children than for items pertaining to women's roles in the public sphere.  相似文献

Public relations communicators can use a variety of techniques to pretest the effectiveness of messages, including readability testing, focus groups, peer and jury reviews, experiments and field testing/test marketing. Another yet-untapped technique is usability research, a set of procedures used for more than 50 years in product and software development. Although usability is a technique that can be applied to any type of public relations message, usability research has particular relevance for enhancing the effectiveness of web sites and other new interactive techniques. This article examines the nature and value of usability research, and the elements of an effective web site based on usability principles. Applications to other types of public relations communications are also discussed.  相似文献

ABSTRACT

In this research, the ecology of perceived social support was examined across multiple contexts (i.e., parents, teachers, classmates, and close friends) in relation to self-perception indices among African American school-age children. Social support is multifaceted and includes positive regard from others, practical support, and stability of care. While there is ample evidence that levels of perceived social support are predictive of self-perceptions, there is less information regarding ecologies of social support. African American children are subject to disparate discipline in schools which can create discontinuity in social support across home and school. Furthermore, research has suggested African American boys and girls have different experiences and expectations across parent, school, and peer contexts. Hence, the question arises as to what ecologies of social support are more or less impactful, and for whom? Cluster and canonical correlation analyses were employed to identify and create relevant ecologies across adult and peer social support items. The results suggested the following: a) continuous positive social support was associated with enhanced self-perceptions, b) some patterns of discontinuity were particularly germane for self-perceptions, and c) relations between perceived social support and self-perceptions outcomes varied by gender. Practical implications are discussed.  相似文献

 This paper attempts to provide a unified account of the rationalization of possibly non-binary choice-functions by “Extended Preference Relations” (relations between sets and elements). The analysis focuses on transitive EPRs for which three choice-functional characterizations are given, two of them based on novel axioms. Transitive EPRs are shown to be rationalizable by sets of orderings that are “closed under compromise”; this novel requirement is argued to be the key to establish a canonical relationship between sets of orderings and choice-functions. The traditional assumption of “binariness” on preference relations or choice functions is shown to be analytically unhelpful and normatively unfounded; non-binariness may arise from “unresolvedness of preference”, a previously unrecognized aspect of preference incompleteness.

Public relations practitioners in this study who were more frequent users of social network sites and social media tools reported greater perceptions of their own structural, expert and prestige power. Forty of 115 members of a PRSA chapter responded to the survey request. In terms of day-to-day practice, the sample matched national samples of practitioners, with manager and technician questionnaire items loading on the exact same factors as in prior studies. However, those enacting predominantly manager roles did not differ significantly from those enacting predominately technician roles in social media use. This study points to the need for future research to examine more closely the use of social media in the daily roles of public relations practitioners.  相似文献

In a classic study, Istomina (1977) found that preschool children remembered more items when remembering served a meaningful purpose then when it was for the purpose of reporting recall to an adult. Istomina's findings have not been replicated in several recent attempts; however, we argue that these attempts have not focused sufficiently on the purpose of remembering. We report a study in which we asked parents to present a set of pictures of 10 grocery items to their 4-year-old children (with the same order of items and number of presentations) in one of two conditions: Either, the remembering fit into a clear functional goal (making a sack lunch), or remembering was itself the goal (in a memory test). In the lunch condition, children were told that they were to remember the items so that they could get them from the "grocer" on the other side of the room in order to make a sack lunch. In the test condition, children were told to remember the items so that they could tell an adult what they were. Children remembered more items when the remembering served the goal of making lunch than when the purpose was simply remembering the items to tell someone else. We discuss the findings in the context of the other replications, some of which created fun activities to contrast with a test condition but often did not embed the remembering as a necessary way of reaching a meaningful goal. We also discuss the likelihood that across differing historical periods and cultural settings, the activities that are meaningful for young children are likely to vary.  相似文献

A symmetric difference metric topology on the collection of binary relations on a countably infinite set provides a new setting for the study of properties of preferences and, as an illustration, is used to lend credence and meaning to some simple intuitions about properties of binary relations. A finite measure on a \(\sigma \) -algebra over the same collection of binary relations is used to provide support for the topological results.  相似文献

The article investigates the city of ?ód? as an exceptional case of a settlement constitutive of different kinds and techniques of power typical of nineteenth century industrial capitalism. We consider Foucault's disciplinary power/biopower through the convergence of the paternalistic gaze of the factory owner, and the Tsarist rule in the Scheibler and Grohman industrial establishment and the nearby workers housing estate. The aim of this article is to investigate a specific locus of peripheral capitalism and the relations accompanying it through the Foucauldian analysis of power. We argue that unique and unstable patterns of correlation of power techniques emerged here. Power is no longer strictly related to the temporal matrix or the functional demands of capitalist production, and only temporarily ossified in contingent configurations. While Foucault's canonical theoretical premises and concepts are of explanatory value, the very relations between them become problematic when confronted with the particular entanglement in ?ód?. Therefore we opt for the new paradigm of power analysis through S. J. Collier's “topological analysis”.  相似文献

We examined gender-specific factors, which might be related to adolescent gambling behavior, using a comprehensive set of predictors from neighborhood, school, family, peer, and intrapersonal domains. Discriminate function analyses revealed a unique pattern of results for each gender. The noteworthy predictors for males were similar to what is found to be predictors of other risk behaviors, suggesting that there may be a similar etiology to gambling participation as found with other risk behaviors. Compared to males, the model for females suggests that parents and peers may have a greater influence on engagement in gambling behavior. Participation in unstructured activities, and risk attitudes/perceptions were the only consistent noteworthy predictors across both males and females. Implications are discussed.  相似文献

When evaluating the effectiveness of an educational program, a sampling strategy known as “multiple matrix sampling” is particularly effective and efficient when the goal of the evaluation is estimating group (as opposed to individual) performance. Although this technique involves sampling both program participants and items and, subsequently, different participants being assessed over different sets of items, the results may be used to estimate those which would have been obtained had all participants been administered all items. The technique is here described in some detail, with advantages and disadvantages discussed, and examples of its application are given.  相似文献

The results of a national survey of public relations instructors regarding their use of active learning are presented as evidence of the development of teaching strategies emphasizing active learning approaches. On average, respondents report they often use the ten active learning approaches identified in the survey. Regression analysis indicates that some demographic characteristics of public relations faculty (eg. academic degree, years of teaching, and age) are significant predictors of willingness to use these activities.  相似文献
