Summary In considering in this paper the origins, development and need for psychosexual counselling to be an integral part of the provision of a counselling service, one must not lose sight of the fact that some higher educational institutions still have no general counselling provision.It is interesting to note that in the UK at a time when the age of consent and voting age were lowered to eighteen years (Family Law Reform Act, 1969, operational 1970 and Representation of the People Act, 1969), and students were rejecting the idea of wardens and academic tutors acting in loco parentis, the National Union of Students (at their annual conference in 1969) passed a resolution pressing for Counselling Services to be established in each higher educational institution-staffed by fully trained personnel, Milner (1974). Nine years later this resolution has not yet been fully implemented.The university community represents a cross-section of the population, any of whom may have a psychosexual problem and seek help from the counselling service. Counsellors must be trained to treat psychosexual problems as part of their normal range of activities.Storr (1960) points out that it is The individual as well as the disease that needs treatment. This applies in counselling as it does in medicine, so that the counsellor should be able to treat the individual as a whole, and at the same time treat his psychosexual problem.University of Reading 相似文献

This paper presents a size reduction method for the inverted file, the most suitable indexing structure for an information retrieval system (IRS). We notice that in an inverted file the document identifiers for a given word are usually clustered. While this clustering property can be used in reducing the size of the inverted file, good compression as well as fast decompression must both be available. In this paper, we present a method that can facilitate coding and decoding processes for interpolative coding using recursion elimination and loop unwinding. We call this method the unique-order interpolative coding. It can calculate the lower and upper bounds of every document identifier for a binary code without using a recursive process, hence the decompression time can be greatly reduced. Moreover, it also can exploit document identifier clustering to compress the inverted file efficiently. Compared with the other well-known compression methods, our method provides fast decoding speed and excellent compression. This method can also be used to support a self-indexing strategy. Therefore our research work in this paper provides a feasible way to build a fast and space-economical IRS. 相似文献

This paper reviews the archival process at the Inter-university Consortium for Political and Social Research (ICPSR), a repository
of digital social science data, and maps ICPSR’s Ingest and Access operations to the Open Archival Information System (OAIS)
Reference Model. The paper also assesses ICPSR’s conformance with the archival responsibilities of “trusted” OAIS repositories,
with the proviso that audit criteria for archival certification are still under development. The ICPSR to OAIS mapping exercise
has benefits for the larger social science archiving community because it provides an interpretation of the reference model
in the quantitative social science environment and points to preservation-related issues that may be salient for other social
science archives. Building on the archives’ long tradition of shared norms and cooperation, we may ultimately be able to design
a federated system of trusted social science repositories that provides access to the global heritage.

Income is not enough: incorporating material hardship into models of income associations with parenting and child development 总被引:2,自引:0,他引:2
Although research has clearly established that low family income has negative impacts on children's cognitive skills and social-emotional competence, less often is a family's experience of material hardship considered. Using the Early Childhood Longitudinal Study, Kindergarten Class of 1998-1999 (N=21,255), this study examined dual components of family income and material hardship along with parent mediators of stress, positive parenting, and investment as predictors of 6-year-old children's cognitive skills and social-emotional competence. Support was found for a model that identified unique parent-mediated paths from income to cognitive skills and from income and material hardship to social-emotional competence. The findings have implications for future study of family income and child development and for identification of promising targets for policy intervention. 相似文献

We examined explicit and implicit processes in response to third-party moral transgressions in children with autism spectrum disorder (ASD). Twenty 4- to 7-year-old children with ASD and 19 typically developing controls evaluated dynamic visual stimuli depicting intentional or accidental harm to persons or damage to objects. Moral evaluations, eye fixations, and pupil dilations toward the stimuli were collected. Results indicate a preserved capacity to understand the mental states of perpetrators and an implicit moral sensitivity to the third-party harms in children with ASD. Nonetheless, children with ASD showed specific sensitivity and emotional arousal when viewing damage to objects. These findings contribute to the understanding of the underlying mechanisms of moral reasoning in ASD and its possible association with the autistic symptoms. 相似文献

Higher Education Institutions (HEIs) across the world have found themselves faced with new challenges on issues of ethics. Much of this has been centred on issues of assessment: plagiarism, buying essays, sharing/lending of previously passed work and the stealing of marked/returned work of others. Institutions still treat academic misconduct as largely a behavioural difficulty rather than an issue of ethics (or education), suggesting that academia places a far greater emphasis on combating new forms of dishonesty than it does on encouraging ethical habits and a healthy ethical environment. To date, the majority of research in this area has examined these forms of academic misconduct from the point of view of the student and/or the university, with the perspective of academics receiving very limited attention. Our hypothesis is that academics are perhaps best placed to provide the education needed to create and sustain an ethical environment, and we argue that being ‘ethically aware’ is a critical factor in the development of academic competence for all parties. This study adds to existing research in three ways: firstly, by highlighting the importance of an overall framework for an ethical environment within HEIs; secondly, by suggesting an ecological model of key parties (the university, students and academics) with responsibility for this environment in assessment; and thirdly, by including new evidence (generated by a survey of academics) to extend our understanding of their views on these issues. 相似文献

ABSTRACTWhat role does academic development have to play in responding to radical cultural shifts in the global landscape? Whose voices and identities are contributing to institutional change? This reflective essay encompasses the perspectives of the four international panellists in the opening plenary of the International Consortium for Educational Development (ICED) 2018 conference in Atlanta, Georgia, USA – Torgny Roxå on ideologies; Chng Huang Hoon on agency and empowerment; Joy Mighty on voices and identities; and Mary Deane Sorcinelli on evidence and outcomes. These perspectives set the stage for the conference, and, brought together in this paper now, they address key conference themes, offer coordinates for reflection, and pose further questions about our profession. 相似文献

The University of Oklahoma College of Medicine has conducted an annual Anatomical Donor Luncheon where families of the anatomical donors met anatomy dissection groups of medical students. The luncheon presented an opportunity for donor family members to share the life story of their loved one with the medical students prior to the start of the anatomy course. This study was designed to understand the impact of the Anatomical Donor Luncheon on families of the donors. Seven families in two different focus groups were included to explore the reactions and attitudes of the donor families to meeting the medical students. Conversations were digitally recorded and transcribed. Qualitative analysis of textual data were coded by three investigators using the Constant Comparative Method. To provide evidence of validity, a form of member checking was utilized. For further triangulation, an analyst not involved in conducting the focus groups or analyzing the data, re-coded all data. This analyst used categories and themes identified by the original analysts, ensuring validity of the themes and any negative cases (data not supporting or contradictory of the established categories and themes). One meta-theme and three sub-themes were identified. The meta-theme was Donor Family Participants Experience Transformation and Closure, and sub-themes were Motivators for Participation, Optimal Venue Factors, and Optimal Medical Student–Anatomical Donor Family Interactions. Study findings indicated the Anatomical Donor Luncheon facilitated closure on the death of their loved one, and transformed their apprehension about the luncheon and body donation into an attitude of gratitude and appreciation. 相似文献
