Quel engagement organisationnel pour les salariés précaires ? Les leçons d’une étude empirique auprès de travailleurs intérimaires

The aim of this article is to focus on contingent workers’ organizational commitment. A review of literature on contingent workers’ attitudes leads to think that this type of work arrangement is associated with a high level of job insecurity, which is not favourable to organizational commitment. However, empirical studies present very contrasting results. This absence of consensus leads us to propose a research model, which puts the emphasis on the way the temporary workers interpret their job arrangement. The model was tested on 208 temporary help service workers. The results highlight the mediating role of perceived job insecurity on organizational commitment, as well as importance of perceived organizational support (POS).     

Primes, contingent attention, and training: effects on a child's motor behavior

The use of primes, contingent attention, and training sessions to assess a child's engagement and skill in six large motor activities was examined using a combination reversal and multiple-baseline design. Assessment was based on four levels: proximity to equipment, touching equipment, unskilled participation, and skilled participation. Before training, priming (suggestion to the child) was more effective than contingent attention for increasing the subject's engagement (but not skill) in five activities and for increasing skilled participation in one activity. Training of four activities in the natural environment effectively increased the subject's skill level in five activities. Thus, training appeared to generalize to one of these five activities in this setting and also to skillfully executed stair climbing in an adjoining setting. After training, primes and contingent attention were sufficient to maintain both the subject's skill level and engagement in all activities. Postchecks in the same setting the following semester with different teachers revealed only slight increases in participation, as compared to previous baselines, but all participation was at the skilled level. Social interaction, which was not experimentally manipulated, did not systematically vary in relation to changes in experimental conditions.     

不同时距加工机制的比较:来自ERP的证据(Ⅰ)

采用事件相关电位的方法分析了不同时距加工机制的差异。实验采用时间两分任务,要求被试形成短(400ms)和长(1600ms)的时间判断标准,然后对7个刺激系列进行短、长的判断。结果表明时间知觉过程可以诱发出一种类似于CNV的慢性负波。对于400ms的短时距加工存在显著的半球效应,右半球的波幅显著高于左半球。1600ms的时距加工没有表现出明显的半球效应。不同时距的加工存在显著的差异。1600ms比400ms加工诱发出更大的CNV波幅。     

偏好反转的兼容性假设的实验研究

本文采用一种新的偏好诱导方法——实物交换方法 ,对偏好反转中的兼容性假设进行实验验证。实验结果支持兼容性假设 ,并发现了一种新的现象 ,即偏好反转的倒置现象。偏好反转与偏好反转的倒置相映成趣 ,为解释风险决策中偏好反转的兼容性假设提供了充足的证据 ,也对风险决策中的纯粹理性提出了更多的挑战。     

THE EXISTENCE OF GOD AND THE CREATION OF THE UNIVERSE

Abstract. Kant argues that any argument for a transcendent God presupposes the logically flawed ontological argument. The teleological argument cannot satisfy the demands of reason for a complete explanation of the meaning and purpose of our universe without support from the cosmological argument. I avoid the assumption of a perfect being, and hence the ontological argument, in my version of the cosmological argument. The necessary being can be identified with the creator of the universe by adding analogical mental relations. The creation of the universe is then shown to reflect modern scientific cosmology as well as stories and metaphors in the Eastern and Western religious traditions and to resolve the problem of evil.
