工作场所的出勤主义行为：组织管理研究的新课题

出勤主义行为是指在生病时依然坚持工作的行为。工作场所的出勤主义行为不仅危害员工的个人健康，还会给企业带来额外的支出。近年来，出勤主义行为逐渐引起管理者的重视，并得到越来越多管理学和心理学研究者的关注。总结以往研究，对出勤主义行为的概念界定和测量方法进行了概述，从个人因素、工作相关因素、组织层面因素和团队层面因素四个方面探讨了出勤主义行为的影响因素，并总结了出勤主义行为对个人健康、工作方面和组织层面的影响。最后，对出勤主义行为未来的研究方向进行了展望。     

小学生对非連貫的单字、数目和图画材料的意义識記

問題意义識記是以对材料的理解为根本条件,是以借助于詞的、反映材料之間的意义联系的概括化了的联想为基础。生活实践和实驗研究都証明意义識記的效果,无論在識記的敏捷性、精确性和巩固性方面都比机械識記好。意义識記对小学生的学习具有重要意义,小学生通过意义識記,可以更有效地把必須記住的东西識記和保持起来。     

The influence of satisfaction and promotability on the relation between career adaptability and turnover intentions

This study examined the relation between career adaptability (CA), promotability, and career satisfaction (CS), and their impacts on turnover intentions (TI). Eight hypotheses were proposed. Based on data collected from a sample of 431 employees in Macau, career adaptability was significantly and positively related to both promotability and CS after controlling for the influences of demographic variables including age, gender, education and tenure. CA, promotability and CS were also significantly and negatively linked to TI. The results further revealed that promotability and CS mediated the effect of CA on TI. The study contributed new insights that may inform career development and retention of employees. Practical implications on how to retain employees were discussed.     

Conflict Minerals in Electronic Systems: An Overview and Critique of Legal Initiatives

The Democratic Republic of Congo has vast natural resources, many of which are regularly exploited by the electronics industry. Unfortunately, in addition to these resources, there are widespread human rights abuses committed by armed groups entrenched in the eastern part of the Democratic Republic of Congo. These armed groups are using profits from these minerals as a source of funding. Their human rights abuses have led to a growing humanitarian interest in the region and prompted the international community to action. This paper explores the conflicts in the Democratic Republic of Congo, provides an understanding of the link between human rights abuses and conflict minerals, and interprets and critiques the legal actions of the international community.     

The Underlying Role of Negative Affect in the Association between PTSD,Major Depressive Disorder,and Generalized Anxiety Disorder

Clinicians and researchers have found differential diagnosis to be difficult, particularly for conceptually similar disorders. One category of particular interest has been distress or internalizing disorders, theorized to be related via an underlying construct of generalized distress or negative affect. The present study attempted to address the comorbidity of three distress disorders - posttraumatic stress disorder (PTSD), major depressive disorder (MDD), and generalized anxiety disorder (GAD) - using latent analyses by controlling for the variance attributable to negative affect. The sample consisted of 265 trauma-exposed individuals who completed self-report measures of PTSD, MDD, GAD, and negative affect. Confirmatory factor analysis was used to test initial model fit. Next, the model was re-computed, controlling for negative affect by regressing negative affectivity at the item-level. Results indicated that a significant amount of variance within and between these diagnostic categories is attributable to negative affect at both the item- and factor-level. The hypothesis that MDD’s non-somatic/affective factor and the GAD factor would have the highest attenuations in factor loadings after controlling for negative affect was supported. Therefore, negative affect significantly influences the co-occurrence of PTSD, MDD, and GAD clinically, emphasizing the need for transdiagnostic interventions for trauma victims.     

The role of retrieval mode and retrieval orientation in retrieval practice: insights from comparing recognition memory testing formats and restudying

The effectiveness of retrieval practice for aiding long-term memory, referred to as the testing effect, has been widely demonstrated. However, the specific neurocognitive mechanisms underlying this phenomenon remain unclear. In the present study, we sought to explore the role of pre-retrieval processes at initial testing on later recognition performance by using event-related potentials (ERPs). Subjects studied two lists of words (Chinese characters) and then performed a recognition task or a source memory task, or restudied the word lists. At the end of the experiment, subjects received a final recognition test based on the remember–know paradigm. Behaviorally, initial testing (active retrieval) enhanced memory retention relative to restudying (passive retrieval). The retrieval mode at initial testing was indexed by more positive-going ERPs for unstudied items in the active-retrieval tasks than in passive retrieval from 300 to 900 ms. Follow-up analyses showed that the magnitude of the early ERP retrieval mode effect (300–500 ms) was predictive of the behavioral testing effect later on. In addition, the ERPs for correctly rejected new items during initial testing differed between the two active-retrieval tasks from 500 to 900 ms, and this ERP retrieval orientation effect predicted differential behavioral testing gains between the two active-retrieval conditions. Our findings confirm that initial testing promotes later retrieval relative to restudying, and they further suggest that adopting pre-retrieval processing in the forms of retrieval mode and retrieval orientation might contribute to these memory enhancements.     

负折扣现象:跨期决策中的自我-他人决策差异

负折扣现象作为一种违背时间折扣假定的现象越来越多地引起研究者关注。本文通过两种指标考察了为自己决策和为他人决策在负折扣现象上的差异。实验1运用二择一选择范式考察人们在为自己决策和为他人决策时对于何时发生负性事件的时间偏好。结果发现,相比较于为他人决策,为自己决策时被试更倾向于选择早些发生负性事件,即更容易产生负折扣现象。实验2运用测量时间折扣率的经典范式考察了人们在为自己决策和为他人决策时的时间折扣率。结果发现,为自己决策时比为他人决策时的时间折扣率更小,更容易出现负折扣率。总体结果表明,为自己决策比为他人决策更容易出现负折扣现象。从情绪卷入的角度看,我们推测,为自己决策时由于更多的预期负性情绪卷入,从而导致更容易产生负折扣现象。     

当代中国医德建设与相对主义医学伦理学

当代西方相对主义医学伦理学有许多建树,但也有其致命性的缺陷,这就是否定医学道德的客观绝对性和普遍性医学伦理准则。在引进、介绍了这种学说之后,需要下功夫同它进行对话,即以医德绝对性与相对性辩证统一的原理,对这种学说进行追问,从中借鉴有益的经验和教训,以顺利全面地推进我国当代的医学道德建设。     

Image-processing algorithms for behavior analysis of group-housed pigs

Computational algorithms of image processing were developed and evaluated to select, by motion detection, images of resting artificial pigs and to segment the pigs (mixture of black and white pigs) from their background. Motion detection of the pigs was implemented by detecting interframe differences of postural behavioral images. This algorithm combines the advantages of likelihood ratio method and shading model method and shows a stable performance under noisy and dynamic illumination conditions. Segmentation of the pigs from their background was implemented by employing multilevel thresholding and background reference techniques. The algorithm automatically determines the number of thresholds needed and produces satisfactory segmentation when both black and white pigs with different image intensities are present at the same time (the most complicated situation). The reference background image is updated so that temporal changes in illumination and/or spatial changes of the pen condition have little effect on the performance of image segmentation. The algorithm employs statistical models of the pigs and background and Bayes hypothesis testing to obtain and update the exposed portion of the reference background. Linear filters were used in this process for updating the parameters. These algorithms will serve as essential components for a novel, behavior-based, interactive approach to assess and control thermal comfort of group-housed pigs, which is expected to result in enhanced animal health and well-being.
