Prolog programming techniques

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.     

The effects of differing type and magnitude of reward on the contrafreeloading phenomenon in rats

This investigation was made to determine the effects of the magnitude of reward on contrafreeloading, using food or water as reward. Two quantities were selected for each level of reward quality—a 20-mg-pellet food reward, a 45-mg-pellet food reward, a .01-cc water reward, and a .1-cc water reward. Seven days of training were followed by three test sessions. There was a significantly higher percent of contrafreeloding demonstrated with food as reward than with water and higher number of barpresses with small reward than with large. It was argued that a more appropriate measure should include reference to performance during training. In this approach, contrafreeloading with food and water were virtually the same.     

Inconsistent response patterns and the prediction of child maltreatment

Inconsistent response patterns have been used with other measures to screen for child maltreatment. To date the inconsistency (IC) scale, a validity scale on the Child Abuse Potential (CAP) Inventory, has not been used as a screening criterion for physical child abuse. The present study examined the responses of 89 physical child abusers and 108 comparison subjects to determine if the CAP Inventory IC scale has any utility in the screening for physical child abuse. While results indicated the CAP Inventory IC scale scores were significantly higher for the physical child abuse group, a series of discriminant analyses indicated that the IC scale did not account for any meaningful variance after variance related to child abuse factors was removed. Further, the results indicated that dependence on the IC scale alone for physical child abuse screening purposes could be expected to produce excessive false positive and false negative classifications.     

The ambiguous embrace: twenty years of IT (ICT) in UK primary schools

School inspection reports, at the end of the 20th Century, in both Scottish and English primary schools, clearly identify the use of ICT as the weakest aspect of professional practice. On this evidence, despite initial certainty of political purpose and considerable optimism regarding its effects on teaching and learning, ICT remains, after twenty years, a marginal force in the education of 5–12 year–olds. Though numerous research studies in the 1980's and 1990's seemed to have identified the conditions for the effective transfer of ICT into primary schools and repeated governmental initiatives invested heavily in both infrastructure and training, teachers have not embraced ICT within their core practice. This paper suggests that the adoption of exclusively rational, perhaps hyper–rational, methodologies, by researchers working in the mainstream of schools and teacher education institutions has resulted in a failure to understand the complex cultural, psychological and political characteristics of schools. Alternative avenues for research are proposed.     

Development of sex-trait stereotypes among young children in the United Staes, England, and Ireland

The Sex Stereotype Measure II (SSM II), a 32-item revision of the Williams, Bennett, and Best Sex Stereotype Measure, was developed to assess children's knowledge of conventional, sex-trait stereotypes defined by American university students. The procedure employed brief stories and human figure silhouettes which were individually administered to 5- and 8-year-old children in the United States, England, and Ireland and group administered to 11-year-olds in the United States. In the United States, knowledge of sex-trait stereotypes was found to develop in a linear fashion between the ages of 5 and 11, with more male traits than female traits being known at each age level. Cross-nationally, there was a high degree of similarity in the nature of the sex stereotypes being learned by the children in the 3 countries, although the rate of learning appeared slower among the Irish children. In all countries there was a clear progression in sex-stereotype learning from age 5 to age 8. English boys had greater knowledge of stereotypes than English girls, but this was not true in Ireland and the United States. Generally, knowledge of male stereotype traits appeared to develop earlier while knowledge of the female traits increased more rapidly between ages 5 and 8. The similarity in sex-stereotype learning in the 3 countries is discussed, and studies in progress in other countries of greater cultural diversity are noted.     

Towards An Understanding of Muslim American Adolescent High School Experiences

The researchers conducted a grounded theory study to explore the experiences of Muslim American adolescents in high school. Findings indicate that students had to navigate unique challenges because of their religious faith, but those obstacles presented opportunities to confront bias and discrimination. Recommendations for how school counselors can support the development of Muslim American adolescents are presented.     

An account of practice: employing drawings and stories to enable reflective learning

Facilitating reflection for personal growth in a business context requires careful thought and planning. As a learning process, Business-Driven Action Learning (BDAL) has two points of focus. It aims to firstly identify and make recommendations regarding a business challenge, whist secondly facilitating potentially significant individual personal learning and growth. The research reported in this account of practice focused on personal learning by exploring the potential for individuals to experience transformative learning during a BDAL process. During the research I used a number of methods including hand-drawn images and in-depth interviews to enable the writing of interpretive stories. Findings revealed that participants found reflection during and after the BDAL beneficial. They gained insights into what they learnt, what changed since the BDAL experience and also what they still need to focus on. The findings have practical implications for the action learning facilitator of BDAL during management development programmes. One of the ways action learning facilitators can initiate the reflection process of new participants is to share the experience of previous participants. ‘Sandy’s interpretive story’, contained in this article, is such an example and includes hand-drawn images of her learning journey. I argue that the use of interpretative stories helps new participants understand programme challenges and stimulates their individual learning journey.     

Foreign patent flows to and from the United Kingdom

A substantial part of the stock of technological knowhow in any given country is determined by foreign companies. Flows of technology are reflected in part by the international pattern of patenting behaviour. This paper examines both the patent applications in the UK by foreign countries and UK patent applications abroad. It concludes that each country is exposed to a subset of world-wide technology determined by the profitability of transfer of new knowhow. Profitability is affected by the size of potential supply of new inventions in donor countries, by the attractiveness of markets for knowhow in recipient countries and by the costs of transfer.
