In this article the perspective shifts to the “upstream” end of the agricultural knowledge and information system (AKIS). Because knowledge policy and strategic decision-making are not the prerogative of the public sector, organizations such as cooperative unions and multinational companies are included. After considering the influence of the changing environment on the nature of the AKIS, the role of knowledge management and policy in the emerging knowledge and information market is examined. Special attention is given to public and private R&D. The article then looks where information technology (IT) fits in and what considerations determine strategic investment in IT projects and sustained services. Some of the European experiences with this strategic investment are evaluated.  相似文献

The purpose of this study was to investigate the effectiveness of a single session of cognitive restructuring in a sample of phobic dental patients. Fifty-two patients were randomly assigned to one of three conditions: cognitive restructuring (modification of negative cognitions), provision of information (about oral health and dental treatment), and a waiting list control condition. Both interventions maximally lasted one hour. In comparison with the waiting list control condition and the information intervention condition, the cognitive intervention condition not only showed a large decrease in frequency and believability of negative cognitions, but also exhibited a clear decline in dental trait anxiety. Analysis at a follow-up of one year demonstrated a further, drastic reduction in dental anxiety in both intervention conditions, wherein the difference among these conditions was not maintained. It is concluded that it is possible to obtain substantial reductions of dental trait anxiety through a single session of cognitive restructuring. Nevertheless, repeated exposure to the dental situation seems necessary for a further reduction of anxiety.  相似文献

Summary In this study on Wilde's phenomenon (Wilde 1950) the two components of disparity, one of them processing displacement, and the other one apparent rotation, are analysed in terms of dependence on the disparity of the end-lines of the pattern (), and on the percentage of magnification (M) of one of the monocular patterns in relation to the other one. It was found that the component of disparity for displacement ' can be expressed as a linear regression equation '=–a+b.The component of disparity for rotation, expressed as a percentage of magnification effective for rotation (M) can be expressed as M=a–b1+b2M.It was concluded that the two components of disparity are processed through independent parallel channels, the processing of the component of disparity for displacement being the faster process, accounting for the larger part of the total disparity.  相似文献

In his article ‘Doing, allowing, and the problem of evil’ recently published in this journal, Daniel Lim attempts to undermine the following claims with respect to God: (1) the doing-allowing distinction exists and (2) the doing-allowing distinction is morally significant. I argue that Lim’s attempt is unsuccessful, and that his understanding of divine providence has the unacceptable consequence of implying that God is the originator of evil.  相似文献

In our review of the literature on women and weight bias (Fikkan and Rothblum 2011), we attempted to cull findings from multiple disciplines that demonstrate the impact (social, educational, and financial) of the stigma of women’s weight. We undertook this for two purposes: the first was to address a gap in the weight bias literature, which tends to make only a side note mention that fat women suffer worse penalties than do fat men; the second, to raise the point that feminist scholars, though highly attuned to pressures on women to be thin, have spent less time discussing the disparate impact for women of being fat, despite the mounting evidence of how much weight bias impacts women. We offered some of our own thoughts on the persisting neglect of this topic among feminist writers, despite previous calls to action (Rothblum 1992, 1994). Given the dearth of attention to what has become one of the most frequent types of discrimination against women (Puhl et al. 2008), we asked: “is fat a feminist issue?” We were delighted with the response from the commentators and the thoughtful exploration they devoted to our question and to this issue within feminist scholarship. Here, we briefly summarize some of the main themes identified by these writers, offer our own thoughts on these themes and repeat their call to action for further study of this important area of women’s lives.  相似文献

The effect of local kinematic changes on anticipation judgments   总被引:1,自引:0,他引:1  
Skilled tennis players rely on a more global than local perceptual strategy when anticipating an opponent’s shot direction in tennis (Williams, Huys, Cañal-Bruland, & Hagemann, 2009). Global perceptual strategy refers to the pick-up of dynamic information across different body areas rather than from a single source such as the arm or racket. We extend previous work by examining the spatiotemporal characteristics of visual information pick-up when anticipating shot direction in tennis. We perturbed information from various body locations by interchanging the dynamics of selected areas with those from strokes played to the opposite side of the court. In addition, we presented each manipulation under four different temporal occlusion conditions (from 240 ms prior to racket-ball contact) to examine the time course of information extraction. Skilled tennis players outperformed less skilled counterparts in predicting shot direction, even at early phases of the opponent’s motion. Moreover, skilled players showed significant decrements in performance when the arms and racket were perturbed, highlighting the relevance of distal information when anticipating opponents’ intentions.  相似文献

So far, evidence for unskilled social behavior in high socially anxious individuals (HAs) is equivocal. One reason may be that shortcomings are often not directly observable. An important shortcoming would be a lack of unintentional mimicry because it communicates sympathy and rapport with the interaction partner. Therefore, we tested whether HAs show less unintentional mimicry of others. Twenty-nine HAs and 43 low socially anxious individuals (LAs) - all female - watched a virtual man (avatar) who displayed a fixed set of head movements while giving an opinionated speech. Four raters scored whether the participants mimicked the avatar's movements within 4 s. The results indicate that HAs did indeed mimic significantly less than LAs. Lacking such pro-social behavior, HAs may indeed be evaluated as less sympathetic by others, confirming their fears of being disliked.  相似文献
