A limited role for the hippocampus in the modulation of novel-object preference by contextual cues

Recent evidence suggests that rats require an intact hippocampus in order to recognize familiar objects when they encounter them again in a different context. The two experiments reported here further examined how changes in context affect rats' performance on the novel-object preference (NOP) test of object-recognition memory, and how those effects interact with the effects of HPC damage. Rats with HPC lesions and control rats received NOP testing in either the same context in which they had previously encountered sample objects, or in a different but equally familiar context. In Experiment 1, the two contexts had very few overlapping cues within or outside the apparatus; thus, the differences between them were global. Consistent with previous results, control rats showed a novel-object preference in both the unchanged and (globally) changed contexts, whereas rats with HPC lesions displayed a preference only in the unchanged context. In Experiment 2, the context shift included only local features proximal to the test objects. The main results were the reverse of Experiment 1--rats with HPC lesions displayed a novel-object preference in both the unchanged and (locally) changed contexts, whereas control rats displayed a preference only in the unchanged context. The findings are consistent with the view that HPC damage does not cause a general inability to recognize objects, nor an inability to encode or store a representation of the context in which the objects are encountered. They suggest instead that HPC damage impairs the ability to remember specific locations of familiar objects within a particular context.     

Protean and boundaryless careers: A study on potential motivators

This paper conceptually links hypothesized scales of the Motivation Questionnaire (SHL (1992). Motivation questionnaire: Manual and users’ guide. Thames Ditton: SHL) to the underlying dimensions of the protean (values-driven and self-directedness) and boundaryless career (physical and psychological mobility) attitudes. Results of regression-analyses (N = 13,000) confirmed most of the hypotheses in terms of the influence of gender, age, education, and managerial experience on motivators linked to the underlying dimensions. A cluster analysis that was conducted to explore how many profiles can be observed when matching work motives to the protean and boundaryless careers, resulted in four motivational groups (Protean career architects, Trapped/lost, Hired/hired hand, and Curious/wanderer). The clusters are discussed in light of the current career literature and provide empirical support for the latest theorizing about the protean and boundaryless career models. Managerial implications and directions for future research are offered.     

Head-putter coordination patterns in expert and less skilled golfers

The authors examined the patterns of expert and less skilled golfers in putting on an indoor surface to 1 of 3 circular targets (1, 3, and 5 m away) in trials with a ball present (and putted) or not present (a practice stroke). As expected, the experts performed better than the less skilled golfers on a large number of outcome and kinematic measures. Displacement and velocity profiles of the head and putter revealed high positive correlations for the less skilled golfers, indicating a dominant allocentric coordination pattern, but high negative correlations for the expert golfers, indicating a dominant egocentric coordination pattern. The observed coordination patterns did not interact with the distance of the intended putt or the presence/absence of a ball. These findings offer preliminary evidence that, although contrary to traditional beliefs, fundamental differences exist in putting coordination modes between expert and less skilled golfers.     

Learning Through Shared Christian Praxis: Reflective Practice in the Classroom

The cultivation of reflective practice has become a commonly accepted goal of theological education. However, theological educators must face the challenge of teaching and assessing reflective practice. Hypothesizing that this concern is best addressed in community, the authors of this article devised a collaborative action‐research project using Thomas Groome's “shared Christian praxis” model. They describe the ways in which they have, over the course of the project, modified their pedagogy to improve their students' reflection on practice.     

A respectable job: Factors which influence young Asians' choice of career

To find out why some college or university courses are particularly attractive to ethnic-minority school-leavers, school pupils and first-year students of South Asian (n=158) and UK origin (n = 158) completed a questionnaire relating to occupational choice. The social position attainable from a 'respected' profession and the ability to work with others who share similar beliefs were found to be of greater importance to subjects from an Asian background than to those of UK origin, who placed greater emphasis on personal growth and autonomy. There was no evidence that the Asian young people were consciously choosing careers with the aim of avoiding discrimination.     

Power,Empowerment, and Equality: Evidence for the Motives of Feminists,Nonfeminists, and Antifeminists

Both feminists and antifeminists claim they do not seek to dominate others, and accuse their ideological opponents of an insidious desire for power. The purpose of this study was to examine the motives of feminists, nonfeminists, and antifeminists by assessing their values in a context in which they would not feel that their motives regarding feminism were being scrutinized. Participants were 126 mostly European-American students. Antifeminist men placed more emphasis on their own power than did other men; but antifeminist, nonfeminist, and feminist women did not differ in emphasis placed on power. Among both men and women, antifeminists placed little importance on equality. Feminist women placed more importance on equality than did nonfeminist women, who in turn placed more importance on equality than did antifeminist women.     

Children's relationships with nonparental adults: Sex-specific connections to early school success

This report asks, Do the social networks of six-year-old girls and boys differ? It then extends previously reported findings by asking, Do different groups of nonparental adults affect the early school success of boys vs girls? Data were collected from the mothers of 162 six-year-olds, using a standard procedure. The networks of boys and girls in one-parent and two-parent households are contrasted throughout the presentation of results. The composition of networks was quite similar for boys and girls, except that each group had more same-sex than opposite-sex peers. In analyses predicting early school success, the number of adult male relatives who took the child on outings away from home was positively related to the child's report card score. This effect, however, was restricted to the subgroup of one-parent (mother-only) boys. This had been predicted, based on knowledge that single-parent boys are the most at-risk subgroup in the sample, the effect of social network resources are known to be accentuated by environmental press, and male adults represent the most salient models for young boys.
