Concurrent validity of Holland's theory for college degreed working women

The study was designed to explore two areas: (1) the concurrent validity of Holland's theory for employed college degreed women using two different operational definitions (Vocational Preference Inventory and the Self-Directed Search) of vocational orientation; and (2) the relationships among same named scales across the VPI and the SDS. Concurrent validity was studied by administering the VPI and the SDS to 179 women workers in occupational environments consistent with Holland's six vocational environments. In general, the findings indicate that the VPI and SDS scales tend to effectively discriminate among the occupational groups consistent with Holland's theoretical framework. In addition, the correlation coefficients for same named scales for the two inventories were all found to be significant. In sum, the results of the study lend some support to the concurrent validity of Holland's theory for employed college degreed women.     

UFO和声称的绑架事件调查(二)——真相与误导

上世纪50年代,UFO目击者和加入这个事件的渲染者使事件急剧升温。1950年,弗朗克·斯库利(Frank Scully)发表了一本引起轰动的书,叫《追踪飞碟》。书中声称,一个飞碟坠毁在新墨西哥的阿兹特克东部的偏僻的高原沙漠上,飞碟的直径为99英尺,里面有16个外星人的尸体。斯库利自己并没有看见这个场景,仅仅是听别人说的。2年以后,发现这个故事是个骗局。关于飞碟坠毁的另一个故事也是发生在新墨西哥,地点是位于罗斯威尔西北部的75英里一处空军基地。据猜测,这次坠毁发生在1947年的7月,由此引发了一系列的事件和争论,并延续至今。坠毁是不容争论的,…     

The ‘We’ in ‘Me’: An Account of Minimal Relational Selfhood

Topoi - Many philosophers contend that selfhood involves a uniquely first-personal experiential dimension, which precedes any form of socially dependent selfhood. In this paper, I do not wish to...     

Mapping differential responses to cognitive training using machine learning

We used two simple unsupervised machine learning techniques to identify differential trajectories of change in children who undergo intensive working memory (WM) training. We used self‐organizing maps (SOMs)—a type of simple artificial neural network—to represent multivariate cognitive training data, and then tested whether the way tasks are represented changed as a result of training. The patterns of change we observed in the SOM weight matrices implied that the processes drawn upon to perform WM tasks changed following training. This was then combined with K‐means clustering to identify distinct groups of children who respond to the training in different ways. Firstly, the K‐means clustering was applied to an independent large sample (N = 616, M_age = 9.16 years, range = 5.16–17.91 years) to identify subgroups. We then allocated children who had been through cognitive training (N = 179, M_age = 9.00 years, range = 7.08–11.50 years) to these same four subgroups, both before and after their training. In doing so, we were able to map their improvement trajectories. Scores on a separate measure of fluid intelligence were predictive of a child's improvement trajectory. This paper provides an alternative approach to analysing cognitive training data that go beyond considering changes in individual tasks. This proof‐of‐principle demonstrates a potentially powerful way of distinguishing task‐specific from domain‐general changes following training and of establishing different profiles of response to training.     

Patterns of emotion-specific appraisal,coping, and cardiovascular reactivity during an ongoing emotional episode

The authors examined emotion-specific patterns of appraisal, coping, and cardiovascular reactivity during real ongoing emotional episodes. In this study, 109 participants performed a neutral opinion-expression task, where a confederate elicited anger, shame, or pride using verbal and nonverbal behavior. The authors assessed cognitive appraisals, emotional reactions, coping, outcomes (state self-esteem and outcome satisfaction), and cardiovascular reactivity. Results indicated substantial and theoretically consistent differences between the 3 emotions (and differences from a nonemotion condition) for cognitive appraisals, self-reported coping, behavioral coping, self-esteem, and cardiovascular reactivity. The results are discussed in relation to their implications for emotion theory and for psychological and physical health. Overall, the results suggest that researchers can study emotion-related issues using authentic emotional reactions.     

Evaluation of agricultural research in Latin America and the Caribbean

This article assesses the state of evaluation, and identifies priorities for improving evaluation, in agricultural research organizations in the region of Latin America and the Caribbean in the early 1990s. Based on thirteen case studies conducted in 1992, the article describes the institutional settings and regional patterns, and trends in evaluation practice. Illustrative cases from Argentina, Brazil, and Guatemala are presented. The organizations studied have extensive experience with evaluation; however, this experience has not been well documented or shared. Evaluation is generally the weakest phase in the management cycle. In the past, most evaluations have been extrinsically motivated, and as such, they have been of little use to local researchers and managers. Obstacles to improving evaluation include the centralization of administrative systems, weak program management, a lack of understanding of potential uses of evaluation in management, and limited knowledge of appropriate evaluation methods. Agricultural research managers feel that evaluation training should be provided as one component of a broader effort covering planning, monitoring, and evaluation. Since joining ISNAR in 1990, he has engaged in research, training, and advisory work on research management, with an emphasis on evaluation. Previously, for fifteen years Horton was head of the social science department of the International Potato Center in Peru. Horton received B.s. and M.S. degrees in agricultural economics from the University of Illinois and a Ph.D. in economics from Cornell University. His current interests include action research and learning, organizational assessment, and institutionalization of planning, monitoring, and evaluation. He worked for fourteen years at the Brazilian Corporation for Agricultural Research, conducting research and development activities in the areas of human resources and of strategic management. He is a full professor at the Department of Social and Work Psychology, Institute of Psychology, University of Brasilia, Brazil, where he teaches and advises at the undergraduate and graduate levels and does research and consulting. His current areas of interest are organizational behavior, training, organizational evaluation, and science and technology management.
