Spatial pattern learning in the radial arm maze

Rats experienced a spatial pattern of baited and unbaited arms in an eight-arm radial maze. The spatial pattern remained constant over trials, but the spatial locations that were baited varied unpredictably. Although there was no evidence of control by the spatial pattern during free choice training trials, the rats’ ability to locate baited arms in forced choice test trials was superior to that of animals in a control condition for which maze arms were not baited in a consistent spatial pattern. This is consistent with the results of experiments showing that spatial choices by rats in a pole box maze are controlled by abstract spatial patterns.     

Correlates of sexual abuse and smoking among French adults

OBJECTIVE: The goal of this study was to examine the association between sexual abuse (SA) and initiation, cessation, and current cigarette smoking among a large representative adult population in France. METHOD: A random sample size of 12,256 adults (18-75 years of age) was interviewed by telephone concerning demographic variables, health practices and beliefs, and health status--for which SA and tobacco questions were included. Bivariate and multivariate analyses were conducted. RESULTS: Nearly 46% of SA survivors were current smokers compared to 34% of non-abused persons (p<.001). Survivors of SA consumed more cigarettes per day than non-abused individuals (14.5 vs. 12.4, p<.01). Survival analysis showed an increased risk of smoking initiation for respondents abused before 18 (adjusted relative hazard=1.55; p<.0001) with referent to the non-abused group. SA was not found to be a significant predictor of current smoking status among those who began smoking after the first incident of SA. Respondents who were not sexually abused were 1.8 times (95% CI, 1.12-2.99) more likely to quit smoking than people who began smoking after they were sexually abused. CONCLUSIONS: The early identification and treatment of sexually abused persons is critical to decrease smoking among adolescents and adults because of the association of SA with both smoking initiation and decreased cessation rates. It may be more difficult to detect an association between SA and current smoking due to the high rates of smoking and lower rates of quitting among the general French population.     

The coming and going: the work of educational developers when admission criteria and desired outcomes change simultaneously

Higher education is facing a conundrum relevant to the field of educational development: expectations regarding entrance criteria and graduation attributes are changing simultaneously. Biggs' model of constructive alignment can be used to analyze the challenges presented by these shifts in expectation and help educational developers understand their pedagogical implications. In the present article, an expanded model is proposed in which entrance requirements are added to Biggs' original conceptualization. In so doing, the length of the “learning journey” – from entrance to outcomes – can be charted. When entrance requirements and graduate attributes change simultaneously, higher education must accommodate learning journeys of varying lengths and nature. Moving targets such as these can engender a sense of frustration, if not helplessness, for academic staff responsible for curricular and pedagogical enhancement. However, rather than responding with a sense of helplessness, the educational developer should see these shifts as a real opportunity to support the implementation of a broader range of student-centred teaching/learning activities. Recommendations related to educational development consultations are offered.     

Editorial

Leadership for learning (LfL) is conceived as a network rather than as a centre within the University of Cambridge Faculty of Education. This paper explores what is understood by the term network, both within LfL and in the wider educational and research communities, and how these understandings are reflected in a number of projects carried out under the aegis of LfL over the last three years. The paper draws out the key distinguishing features of these activities and, using the five principles of leadership for learning, explores the degree to which these activities have contributed to the creation and transfer of new knowledge. The paper concludes by proposing a model for knowledge-building which draws on the work of LfL and suggests ways in which this model may be of use to the wider educational community.     

Adult Students at Two-Year Colleges: A Longitudinal Study

Abstract

Adults constitute a continually increasing proportion of students at two-year colleges. While adult students presumably have special needs, little is known about them. This study focused on the characteristics and needs of 17,137 students enrolled in 100 randomly selected two-year colleges across the country, separately for different age levels. Using a wide variety of variables collected at entrance, after one term, at graduation, and three years after graduation, differences by sex among the following four age groups were ascertained: age 19 or younger, 20–24, 25–39, and 40 or older. Major trends with age, differences among age groups, and interactions between age and sex were found for a number of variables: abilities, grades, attrition, self-perceptions, aspirations and goals, competencies, job values and preferences, satisfaction with and rating of various aspects of the college, expressed needs for help, extracurricular participation, outside work during school, postgraduate jobs obtained and how obtained, job satisfaction, percent going to and graduating from four-year programs, and preference for entering a two-year program if they had to do it all over again. Adult students do have many special needs that vary with age level. We think a repeat of the study but comparing across other groupings of adults would be desirable, even though extreme diversity also exists within such groups. Another consideration is that many new kinds of adult students will in the future be entering postsecondary education in large numbers.
