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

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

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

It is reasonable to assume that a subject of presumably universal appeal must rely on just one style. In spite of its universality, mathematics employs many styles. In particular, there are many styles of proof. In this paper we present and analyse a number of proofs of a property of the area under an hyperbola due to Gregory of Saint-Vincent, a mathematician of the first half of the seventeenth century. There is a baroque and prolific quality to the architecture of his proofs, and this quality points to a connection between a culture and the discovery of a mathematical theory. An historical perspective shows that, in addition to many styles, the universality of mathematics implies a variety of procedures.This work was carried out during a period as guest professor at the Institut de physique théorique, Université de Louvain. 相似文献

Modelling and simulation of switching devices with bond graphs is a subject which has no totally satisfying solutions. In this paper, switching devices are represented by flow or effort sources, with a variable circuit topology at switching time. For the simulation, the usual method uses causality resistors to insure integral causality to energy storage elements. The choice of those resistors is quite arbitrary and can lead to stiff systems. We propose, for linear systems, an approach without such resistors. When components lose the integral causality, the order of the state vector changes, provoking the use of pulse variables. A solution is proposed to compute the amplitude of the pulse and the value of the new variables. 相似文献
