中国情境下公共服务动机的理论构建与绩效转换机制

准确把握基层公职人员的公共服务动机是提升工作绩效、完善人力资源管理的重要前提。现有公共服务动机研究忽略了中国情景的特殊性, 对公共服务动机的微观激发机制及其消极绩效影响也关注不足。本研究从中国情景下公共服务动机的概念、核心构成要素、激发机制以及绩效结果入手, 从三个方面系统地构建适合中国场景的公共服务动机理论：第一, 将公共服务动机视为混合动机概念, 基于扎根理论的定性方式识别基层公务员公共服务动机的构成要素与核心内涵, 并据此开发本土化、多维度的公共服务动机量表; 第二, 从微观激发机制出发, 探讨受益人接触、自我倡议、观念反思等机制对个体公共服务动机的激发作用; 第三, 从积极影响和消极影响两个方面探讨公共服务动机与个体公务员行为间的关联及其机理。本研究既响应了国内公共管理学界长期以来发展本土理论的呼声, 亦为政府部门完善公共人事政策提供切实思路和实证依据。     

流动儿童的社会善念水平及其提升

采用社会善念范式,探究流动儿童与非流动儿童的社会善念水平是否存在差异,以及移情训练对流动儿童社会善念水平的提升作用。结果表明：（1）流动儿童的社会善念水平低于非流动儿童;（2）移情训练活动可以提升流动儿童的社会善念水平。本研究扩展了社会善念的研究领域,为促进流动儿童社会互动技能和亲社会行为提供了一定的理论支持和实证参考。     

Cognitive enhancement, human evolution and bioethics

The goal of this article are three-fold. The first is to explore the relations between the properties designated by the terms "human", "post-human," "Transhuman", and to clarify the corresponding "isms". The second is to scrutinize the current techniques for cognitive enhancement in order to assess their relations with the three categories just mentioned, and, with the specific ethical issues that they are raising. The third is to examine whether general ethical principles could be invoked either in favor of or against, the normative proposals of post- and trans-humanism, and to consider how compatible the types of enhancement presently developed are with respect to these principles.     

Stress and emotional memory: a matter of timing

Stressful events activate the amygdala and a network of associated brain regions. Studies in both humans and rodents indicate that noradrenaline has a prominent role in this activation. Noradrenaline induces a hypervigilant state that helps to remember the event. This mnemonic effect is enhanced when the situation is so stressful that substantial amounts of corticosteroids are released and reach the amygdala. The combination of the two hormones leads to optimal strengthening of contacts and thus memory. Yet, rises in corticosteroid levels that are not precisely synchronized with noradrenaline release do not act synergistically but rather prevent or suppress the effect of noradrenaline. This dynamic interaction illustrates the adaptive and potentially protective capacity of corticosteroids regarding traumatic memories.     

Cognitive aging and flight performances in general aviation pilots

Unlike professional pilots who are limited by the FAA's age rule, no age limit is defined in general aviation. Our overall goal was to examine how age-related cognitive decline impacts piloting performance and weather-related decision-making. This study relied on three components: cognitive assessment (in particular executive functioning), pilot characteristics (age and flight experience), and flight performance. The results suggest that in comparison to chronological age, cognitive assessment is a better criterion to predict the flight performance, in particular because of the inter-individual variability of aging impact on cognitive abilities and the beneficial effect of flight experience.     

The use of visual and automatized behavioral markers to assess methodologies: a study case on PIT-tagging in the Alpine newt

In various research fields, biomarkers are now widely used as tools for assessing individual integrity. The recent advances in quantification methods for behavioral patterns, such as computerized video-tracking procedures, make them valuable biomarkers. However, the corollary of these novelties is that they remain relatively unknown and unused. In this study, we show that such tools can assess the validity of research methods, such as individual recognition. To demonstrate this, we employed, as a model, a marking method (passive integrated transponder [PIT] tagging) widely used in amphibians. Detailed visual observations and video-tracking methods were complementary in highlighting components at different behavioral scales: locomotion, feeding, and breeding. We illustrate the scientific and ethical adequacy of the targeted marking method but also suggest that more studies should integrate behavioral analyses. Such biomarkers are a powerful tool for assessing conservation concerns when other techniques cannot detect detrimental effects.

The sound of time: cross-modal convergence in the spatial structuring of time

In a new integration, we show that the visual-spatial structuring of time converges with auditory-spatial left-right judgments for time-related words. In Experiment 1, participants placed past and future-related words respectively to the left and right of the midpoint on a horizontal line, reproducing earlier findings. In Experiment 2, neutral and time-related words were presented over headphones. Participants were asked to indicate whether words were louder on the left or right channel. On critical experimental trials, words were presented equally loud binaurally. As predicted, participants judged future words to be louder on the right channel more often than past-related words. Furthermore, there was a significant cross-modal overlap between the visual-spatial ordering (Experiment 1) and the auditory judgments (Experiment 2), which were continuously related. These findings provide support for the assumption that space and time have certain invariant properties that share a common structure across modalities.     

Measuring consciousness: task accuracy and awareness as sigmoid functions of stimulus duration

When consciousness is examined using subjective ratings, the extent to which processing is conscious or unconscious is often estimated by calculating task performance at the subjective threshold or by calculating the correlation between accuracy and awareness. However, both these methods have certain limitations. In the present article, we propose describing task accuracy and awareness as functions of stimulus intensity (thus obtaining an accuracy and an awareness curve) as suggested by Koch and Preuschoff (2007). The estimated lag between the curves describes how much stimulus intensity must increase for awareness to change proportionally as much as accuracy and the slopes of the curves are used to assess how fast accuracy and awareness increases and whether awareness is dichotomous. The method is successfully employed to assess consciousness characteristics on data from four different awareness scales.     

Distinct and shared cognitive functions mediate event- and time-based prospective memory impairment in normal ageing

Prospective memory (PM) is the ability to remember to perform an action at a specific point in the future. Regarded as multidimensional, PM involves several cognitive functions that are known to be impaired in normal ageing. In the present study we set out to investigate the cognitive correlates of PM impairment in normal ageing. Manipulating cognitive load, we assessed event- and time-based PM, as well as several cognitive functions, including executive functions, working memory, and retrospective episodic memory, in healthy participants covering the entire adulthood. We found that normal ageing was characterised by PM decline in all conditions and that event-based PM was more sensitive to the effects of ageing than time-based PM. Whatever the conditions, PM was linked to inhibition and processing speed. However, while event-based PM was mainly mediated by binding and retrospective memory processes, time-based PM was mainly related to inhibition. The only distinction between high- and low-load PM cognitive correlates lies in an additional, but marginal, correlation between updating and the high-load PM condition. The association of distinct cognitive functions, as well as shared mechanisms with event- and time-based PM, confirm that each type of PM relies on a different set of processes.
