We describe an editor geared to recursive Prolog procedures. It is similar to the structure editors built for many programming languages, except that instead of just ensuring the correctness of the syntax of the procedures built by the editor, the editor also ensures the correct use of recursion. By correct here we mean that the recursive procedure is guaranteed to terminate and to be well-defined. Within these constraints we have tried to ensure that the range of procedures that can be built is as complete as possible.  相似文献

In this paper we introduce the concept of a Prolog programming technique. This concept is then distinguished both from that of an algorithm and that of a programming cliché. We give examples and show how a knowledge of them can be useful in both programming environments and in teaching programming skills. The extraction of the various techniques is outlined. Finally, we discuss the problem of representing techniques where we conclude that the most promising approach is the development of a suitable meta-language.  相似文献

The challenges facing children in the 21st century are immense and will need to be faced if we are to achieve the goal of child protection for all. Three specific constraints on child protection are examined in this article, namely poverty, HIV/AIDS infection, and war. The authors use their experience in Africa to raise issues of resilience and adaptation, dangers to child protection programs, and possible solutions. Poverty can be both financial and psychological, and this affects the effect of prevention programs. In many African and Asian countries, the AIDS pandemic has changed the social structure of society with AIDS orphans and children infected and affected by HIV/AIDS becoming more common. The impact has devastating effects on the way we view child protection and in particular child sexual abuse. The consequences of post-traumatic stress resulting from war needs to be addressed, and the development of programs that place children in the center of relief programs to foster a culture of child protection is essential. Finally, the article notes that the picture is not overly pessimistic and the examines the achievements in the field of children's rights which underpin all programs aimed at protecting children and the future need to consolidate successes achieved.  相似文献

Although the need for personal counseling services is on the rise across college campuses in the United States, many community colleges do not offer personal counseling services on campus. Instead, community college counseling services focus primarily on academic and career advising. The purpose of this study was to survey community college students in North Carolina to determine their interest in and need for a personal counseling center on campus. Participants were 134 men and 202 women, 18–68 years of age. Of the participants, 70% indicated that having a personal counseling center on campus would be “very helpful” or “helpful.” Results are discussed, and recommendations are made for college counselors working in community college settings.  相似文献

How often do we as teachers begin to prepare a conference on one of the children in our class and suddenly realize that we don't have much specific information? We have a general impression about the child and may remember some specifics — how she loves to spend time in the housekeeping corner or at the easel — but when we start to fill out our conference form, we have only scanty information to share with her parents. Often the children who cause us to scratch our heads at conference time are those easy, average children. They are the ones who most often escape the teacher's attention while we are coping with those children with more pressing needs — the aggressive or demanding child, the painfully shy child, or the ones having most trouble with separation. But even though we might have focused a good deal of attention on an acting-out child, we still may have forgotten to notice if that child is right- or left-handed, if he can hold a pencil correctly, or if he pedals a trike.  相似文献

Dolls are a part of every culture. From the beginning of time, children have played with dolls, using them as friends and confidants, as surrogates while the child recreates domestic situations, and as props for acting out fantasies. Dolls help children practice the nurturing role they see their parents performing. Dolls can be loved or punished, kissed or spanked, rocked to sleep or sent to bed with no supper, providing an acceptable outlet for a child's range of emotions. Children have the same kind of control over their dolls' lives that parents have over the lives of their children. Eden Ross Lipson, children's book editor ofThe New York Times, notes the universality of children's play with dolls. She suggests, The will to create dolls, to give them personalities and family relationships, to imagine their emotions and act out fantasies in which they figure, is one of the characteristics that makes us all more alike than different as human beings (Lipson, 1986).Blakely Fetridge Bundy is a writer, consultant, and teacher at Willow Wood Pre-School in Winnetka, IL.  相似文献

Erratum . Journal of Research in Reading 29:2, 252 In this article, we discuss two characteristics of the majority of current behaviour‐ and molecular‐genetic studies of reading ability and disability, specifically, the ascertainment strategies and the populations from which samples are selected. In the context of this discussion, we present data that we collected on a sample of Swahili‐speaking siblings from Tanzania. With this sample, we (1) explore the efficiency and practicality of the single proband sibpair design and (2) provide data on the predictability of reading and spelling performance using reading‐related componential measures in a novel Swahili‐speaking sample. Specifically, we present the selection criteria, discuss the pattern of behavioural and behaviour‐genetic results obtained on the sample and compare these results with those available in the literature. We report behavioural and behaviour‐genetic correlations in this sample that are comparable with other studied samples in other languages, and discuss the similarities and differences. Thus, we demonstrate the suitability and effectiveness of the single sib ascertainment method for genetic analyses of reading ability and disability in novel samples in previously unstudied languages.  相似文献

Shifts are occurring in discourses regarding childcare, creating changes in the development of early childhood education programmes. Childcare, as an important ‘investment’ for the future success of nation-states, is a discourse recently developed across a variety of political arenas, both globally and in local governing bodies and institutions. This article will characterise the dual processes of change affecting how childcare is understood – the need to invest in children, coupled with the scientisation of childhood – in order to place in context the transforming discourse around parenting, and mothering in particular. Two theoretical frameworks guide this analysis: (1) a review of alterations to kindergarten in Ontario, Canada, within an understanding of the ‘social investment state’ welfare regime, reliant on ‘human capital’; and (2) the application of Foucault's analysis of biopolitical apparatuses to show how changes to children's education will monitor and intervene in the formation and regulation of populations. Through an analysis of Ontario's Early Learning Programme, this article will demonstrate the problems of policy that ignores gender while simultaneously redefining ‘good’ parenting.  相似文献

This document is the Introduction to the 8th annual Directory of Australian Public Libraries. It provides a good overview of the dictionary of library information compiled system by system. The second document (Appendix A) is the survey form sent out to all of Australia's public libraries in order to gather the data which is assembled in the 8th annual Directory. This document shows the questions that elicit a range of individual library system data. Many readers will want to compare this document with the U.S. equivalent.  相似文献
