Psychology Has to Deal with Efferences Too

The authors argue that F. Mechsner's (2004) perceptual-cognitive approach is an important contribution to the current discussion of motor control. Mechsner presents convincing evidence against direct motor control. Nevertheless, the mechanisms by which perceptual-cognitive representations determine efferent commands must still be clarified.     

骨髓捐献人中途拒捐的民事责任探析——基于信赖保护的视角

基于捐献行为的公益性、单务性和人身性,各国法律赋予捐献人任意撤销权,但是出于对捐献人允诺的信赖而改变自身处境的接受人利益也应该得到保护.从信赖保护的视角出发,在血型高分辨检测之前,捐献人一旦签订了捐献协议,即负有保护接受人信赖利益的义务,捐献人虽然有权中途拒捐,但应当承担信赖赔偿责任.     

Generalized Trust Through Civic Engagement? Evidence from Five National Panel Studies

According to a popular version of social capital theory, civic engagement should produce generalized trust among citizens. We put this theory to the test by examining the causal connection between civic engagement and generalized trust using multiple methods and multiple (prospective) panel datasets. We found participants to be more trusting. This was mostly likely caused by selection effects: the causal effects of civic engagement on trust were very small or nonsignificant. In the cases where small causal effects were found, they turned out not to last. We found no differences across types of organizations and only minor variations across countries.     

Older English churchgoing women as voluntary providers of welfare

The contribution of UK Christian churches to the provision of welfare projects, relying largely on a pool of volunteer labour, has long been recognised by a number of commentators. What is also now recognised is that it is women who have made up and still make up the majority of these volunteers but they are a largely ageing – and declining – population, hence the question arises as to whether most churches in Britain can continue to provide the same levels of support for much longer. This article considers the factors which have made women longstanding and committed individuals in both their churches and their civic communities, and argues that the same conditions do not pertain for their children. Unless more volunteers are forthcoming from secular organisations, we are likely to be seeing a significant gap in voluntary welfare provision at precisely the time when state funding for welfare is being drastically cut and more volunteers are needed, not fewer.     

Care Versus Control: The Identity Dilemmas of UK Homelessness Professionals Working in a Contract Culture

UK voluntary and community sector organizations (VCOs) play a key role in caring for homeless people. However, there are widespread concerns about the impact of increasing government contracting on the quality of their services. This paper examines understandings of homelessness and identities as homelessness professionals, as expressed by VCO professionals. By so doing, it considers how ‘partnership working’ enables or undermines their capacities to care. The paper uses 24 in‐depth interviews and four focus groups with London‐based homelessness professionals. Professionals expressed deep tensions in their experience of their role. On one hand, they reported a deep ethical commitment to care and to develop quality supporting relationships to respond to their clients' complex needs. On the other, their capacity to care was undermined by their dependence on statutory resources and the controls this involved over the way VCOs delivered care. Professionals had to adjust to statutory monitoring frameworks and hard performance targets, which detached them from the human and intimate encounter with their clients and constrained their person‐centred caring interventions. The findings highlight the contradictory nature of contemporary systems of ‘joined up’ welfare that neglect the very human and complex nature of the issues that they were originally created to address.

Effect of Sensory Deprivation on Maximal Force Abilities from Local to Non-local Digits

Abstract

The present study investigates the effect of sensory deprivation of the index and middle finger on motor function of all digits during maximal voluntary force production tasks. A total of 27 subjects performed maximal isometric pressing tasks by using different instructed finger combinations. Subjects completed the same tasks in two visits: a control visit when they had normal sensory feedback in all fingers, and an anesthesia visit when digital nerve blocks were performed on their right index and middle fingers. We evaluated three aspects of motor adaptation on both local (anesthetized) and non-local (non-anesthetized) digits during maximal force production: (1) task-relevant and overall force magnitude, (2) force directional application, and (3) digital individuation and force sharing. Our results indicate that selective digital anesthesia resulted in decreased maximal force magnitude, changed direction of force production, and significant changes extended to non-local digits. The motor weakness and inefficiency revealed in the non-local digits implies that sensory information from each digit can be shared across the digits to assist motor execution within the same hand.     

Involuntary and voluntary demotion: employee reactions and outcomes

ABSTRACT

Demotion has received little attention from scholars and practitioners alike. The purpose of this study was to assess empirically the reaction to, and outcomes of, both involuntary and voluntary demotion. Drawing on 49 semi-structured in-depth interviews with 28 involuntarily demoted workers and 21 voluntarily demoted workers, we develop a conceptual model using organizational justice theory and person-job fit of the reaction to and outcomes of demotion. We show that involuntarily demoted individuals might react by expressing turnover intentions and lower motivation and commitment, indicating that the demotee’s reaction is related to perceptions of fairness. Voluntary demotion is related to a better work-life balance, greater satisfaction, less stress and burnout and is perceived to be a viable phased retirement option by older workers. In addition, the findings highlight the role of demotion-related stigma, status loss, identity threat, and age in the way employees react to the experience of demotion.
