Collective efficacy beliefs in student work teams: Relation to self-efficacy, cohesion, and performance

A measure of collective efficacy was developed and administered to undergraduates working in project teams in engineering courses. Findings in each of two samples revealed that the measure contained a single factor and was related to ratings of team cohesion and personal efficacy. Collective efficacy was also found to relate to indicators of team performance at both individual and group levels of analysis. Consistent with social cognitive theory, collective efficacy was a stronger predictor of team performance than team members’ perceptions of their self-efficacy. We consider the implications of these findings for further research, theory, and practice on team functioning within occupational and educational settings.     

集体效能研究述评

从20世纪80年代中期开始,国外自我效能的研究表现出从个体效能向集体效能的转变,集体效能是自我效能在集体水平上的扩展。在效能内涵和效能形成上,集体效能与个体效能存在着密切的相互作用,但在效能的测量上,集体效能又有着许多不同于个体效能之处,与个体效能相比,集体效能的研究在整体上还存在着明显的不足。     

Locomotor pattern and mechanical exchanges during collective load transport

While the locomotor behavior of humans walking alone, loaded or unloaded, has been extensively studied, the locomotor behavior of humans transporting a load collectively is very poorly documented in the biomechanics literature. Yet, collective carriage is a task commonly performed in sport (CrossFit), military and health care (carriage of an injured person) activities and is a task that raises growing interest in robotics (Cobots). The primary aim of our research was to test the hypothesis that the mechanical cost of locomotion is comparable when two individuals are transporting an object collectively and when they are walking alone. To test this, the movements of ten pairs of individuals walking side by side, separately or while transporting collectively an object, were recorded with a three-dimensional motion analysis system (Vicon©). Our results show a similar pattern in the periodic displacement of the center of mass and in mechanical costs, between individuals walking alone and individuals carrying a load collectively. Moreover, a better pendulum-like behavior was found in the sagittal plane and in 3D for the pairs of individuals carrying an object, which suggests that the saving in mechanical exchanges is higher when two individuals are carrying an object collectively than when they are walking alone. The values of the parameters measured in our experiment could be used as a benchmark for the implementation of collective carriage tasks in robotics.     

‘Working on a rocky shore’: Micro-moments of positive affect in academic work

Neoliberal ideologies, marketization and performative regimes associated with recent reforms in universities have exerted considerable pressure on academic working conditions and subjects in recent years. While analysing these pressures is important, it is also productive to consider the ways in which academics engage in moments of resistance by mobilising resources beyond those of critique. This paper therefore focuses on joy and positive affect in the everyday moments of academic life. It utilises the feminist methodology of collective biography to explore ways of making the restricted spaces of our working day more expansive and finding within them unexpected openings for joy. Our analysis of the stories included in this paper traces the mercurial and ambiguous affective atmospheres of academic work. We suggest that joy is founded upon connections with others, that it arises in different academic spaces and that it can lead to revised knowing of ourselves. We argue that the glimpses of joy evident in this paper provoke affective attunement within the everyday, sensitizing us to other fragments of joy and providing strategies to strengthen that resistance.     

Guilt in bereavement: Its relationship with complicated grief and depression

This study investigated the relationship between guilt and well‐being of bereaved persons, and explored potential differences in the associations between guilt‐complicated grief (CG) and guilt‐depression. In total, 1358 Chinese bereaved adults were recruited to fill out questionnaires. Participants (N = 194) who had been bereaved within 2 years of the first survey, filled out the same questionnaires 1 year later. Higher guilt was associated with higher degrees of both CG and depression. The level of guilt predicted CG and depression symptoms 1 year later. Bereavement‐related guilt has a closer association with CG than depression. Responsibility guilt, indebtedness guilt and degree of guilt feeling are more prominent aspects of guilt in CG than in depression. These findings demonstrate the significant role of guilt (perhaps a core symptom) in mental health of the bereaved, having implications for identifying persons with grief complications and depression.     

马克思每个人自由而全面发展思想的四个维度

马克思每个人自由而全面发展的理论内蕴着四个维度的内涵：人类的历史发展导向每个人自由而全面发展;个人自由发展的普遍性和全面性;从虚幻的集体到真实的集体的发展;建立在“共同占有的基础上”“重新建立个人所有制”的基础上。     

Observation as a method to enhance collective efficacy: An integrative review

ObjectivesThis review provides an integrative argument for the use of observation as an intervention to manipulate individual collective efficacy beliefs in sports teams.DesignAn exploration of the conceptual and empirical evidence underpinning observation-based interventions for increasing collective efficacy.MethodA presentation of reflections on the following. First, we reflect on existing techniques used to increase self- and collective efficacy beliefs. Second, we consider collective efficacy in the context of observational learning and the various modeling techniques employed in the sports and motor performance literature. Third, we highlight relevant literature from neuroscience, outlining the analogous neural pathways evident for social cognition (i.e., collective efficacy) and observation.ResultsThis review presents a case for the use of observation interventions to manipulate collective efficacy, drawing upon social psychological frameworks of human behavior, the observation-based literature, and contemporary understanding of brain and behavior.ConclusionsObservation-based interventions are suited for collective efficacy manipulation in sport. There is a need to advance understanding of this relationship in order to maximize improvements in collective efficacy across group contexts.
