The authors assessed the reliability and validity of the Web‐based version of the Career Key (L. K. Jones, 1997). Ninety‐nine undergraduates completed the Web‐based version of the Career Key and the Self‐Directed Search‐Form R (J. L. Holland, 1994) in counterbalanced order and completed a second Career Key administration 2 weeks after completing the first test administration. Test—retest reliability ranged between .75 and .84 With the exception of the Conventional scale (.47), all concurrent validity coefficients were at or above .65.  相似文献

Through in‐home interviews with 142 married couples, we explored how husbands' and wives' marriage work with close friends and one another was linked to their perceptions of marital quality. Results showed that husbands engaged in more marriage work with their wives than with close friends, whereas wives engaged in similar levels of marriage work with their close friends and husbands. For wives, marriage work with their spouses was found to moderate the relationship between marital quality and marriage work with friends. At low levels of marriage work with their spouses, wives' marriage work with friends was negatively related to their reports of marital love and positively related to reports of ineffective arguing. In contrast, at high levels of marriage work with their husbands, no significant relationship was found between wives' marriage work with friends and marital quality for wives. Findings underscore the role of spouses' friendships and suggest that the strength of spouses' ties to one another is linked to the social context they and their close friends create.  相似文献

In this study, we identified unique clusters of parenting behaviors based on parents' school involvement, community involvement, rule‐setting, and cognitive stimulation with data from the Panel Study of Income Dynamics—Child Development Supplement. In early (n=668) and middle adolescence (n=634), parents who provided high cognitive stimulation (i.e., cognitive enrichment parents) or engaged in all parenting behaviors (i.e., engaged parents) had the highest family income, parent education, and percentage of European Americans. Adolescents of cognitive enrichment or engaged parents often evidenced the highest academic and social adjustment. Adolescents whose parents set a large number of rules (i.e., “Rule setters”) or were also heavily involved in the community (i.e., the “Managers” cluster) had the lowest adjustment.  相似文献

Often it is necessary to estimate the parameters of a model or unknown system. Various techniques exist to accomplish this task, including Kalman and Wiener filtering, least-mean-square (LMS) algorithms, and the Levenberg-Marquardt(L-M) algorithm. These techniques require an analytic form of the gradient of the function of the parameters to be estimated. A key feature of the simultaneous perturbation stochastic approximation (SPSA) method is that it is a gradient-free optimization technique (Spall; 1992,1998a,b, 1999). In the current problem, the function of parameters to be identified is highly non-linear and of sufficient difficulty that obtaining an analytic form of the gradient is impractical. Therefore, in this paper the

performance of the SPSA algorithm will be examined in terms of parameter selection, data requirements, and convergence performance on this non-linear problem. Results will be reported on both a first-order "standard" implementation of SPSA and on a second-order version of SPSA that tends to enhance convergence.  相似文献

Questions identifying foreigners have been included in official statistics since the census of 1841 when place of birth was first asked. This question has since been used in many sources. It was later supplemented by a question on each parent's birthplace so that the children of immigrants could be identified. More recently, direct questions on ethnic origin have been introduced. One notable exception to the use of a direct question is the census, which for political reasons has so far been unable to include such a question. The Home Affairs Committee recommended that a direct question be asked in the next census, and also recommended a form of that question. This recommended form is technically poor. In light of the political objections to a direct question, there is a need to address political issues rather than dwell on technical detail.  相似文献

This article is about the way in which the processes of diminution and elaboration can be detected in gendered accounts of identity formation. Firstly, it considers the ways in which power is denied to women through a series of reductions, restrictions and controls, and looks at the ways in which men, in contrast, elaborate their identities via a range of enlargements and extensions. The codex of the title refers to the role of the ‘Law’, in Kristeva's sense of the term, in authorizing such arrangements. The codpiece offers a metaphor for elaboration and extension: a male form of extension and elaboration. The codicil, an appendage to a last will and testament, is intended to convey the position of women as appendages, afterthoughts, marginal notes. The article is an example of what Pullen and Rhodes have called ‘dirty writing’, that is to say, it is written with the purpose of allowing the intrusion of the author into the text: with a deliberate confusion of the authorial standpoint and the content. Dirty writing contaminates. This article is written with the intention of contaminating the regulatory mechanisms of the production of the codex, to reveal the enormity of the codpiece and to permit the codicil to assume a role within the codex rather than simply occupying the position of appendage to it. The article is not auto‐ethnographic, although it has elements of autobiography. Rather this article seeks to ‘undo’ gender by fragmenting the coherence of the codex. More tentatively, it seeks to lay bare the male erection which is concealed by the codpiece and to expose it for what it is: an elaborate construction — an elaborate creation masking a less adequate membership. And so this piece of writing attempts to undermine the extravagance of masculine forms of writing; of writing to produce the codpiece, writing as conceit; writing which is antagonistic to fragmented experience. It will not satisfy some, it will irritate others. The article is unbalanced, unresolved: like life itself. It is about stories, illustrations, asides, observations. It is also, with all its attempts to subvert, (with all its attempts to make it ‘dirty’), a piece of male writing.  相似文献

The interpersonal relationship between doctor and patient is fundamental to general medical practice. In this paper we explore the ways in which general practitioners make sense of the changing political economy of this relationship, as it is restructured by ideas about the patient as consumer, and as it increasingly constitutes the consultation as a point of interaction that may be intrinsically therapeutic. In particular, we explore the ways in which the consultation is the site of negotiated power relations between doctor and patient, and is the site of the doctor's negotiation of powerful discourses of professional and institutional identity.  相似文献

This paper describes the evaluation of a three year Initiative run by the YMCA. The aim of the Initiative was to set up 30 different projects in YMCA centres in England, to provide help and support to the parents of teenagers. The Initiative was evaluated by the Trust for the Study of Adolescence. Funding was agreed for 29 projects, which included group‐based courses, ‘Dads and Lads’ projects, mediation schemes, transition evenings, and families and computing courses. A variety of outcomes from these projects are identified, both for parents, young people, project workers, and the YMCA as an organisation. Key issues and learning points from the Initiative are also identified. Finally, some general comments are made about strategies to provide support to the parents of teenagers.
