Leg-extension strength and chair-rise performance in elderly women with Parkinson's disease

The lower extremity performance in elderly female patients with mild to moderate Parkinson's disease (PD; n = 12) and controls (n = 16) was compared. Isometric dynamometry and force-plate measurements were used. PD patients had lower (p < .05) bilateral (BL) maximal isometric leg-extension force (MF), BL isometric MF relative to body mass, and maximal rate of isometric force development than control participants. BL strength deficit was greater (p < .05) in PD patients than in controls. A significantly longer chair-rise time and lower maximal rate of vertical-ground-reaction-force development while rising from a chair was found in PD patients than in controls. These findings suggest that elderly women with PD have lowered voluntary isometric force-generation capacity of the leg-extensor muscles. Reduced BL leg-extension strength might contribute to the difficulty of individuals with PD to rise from a chair.     

Globalisierung und die Veränderung sozialer Ungleichheiten in modernen Gesellschaften

This article deals with the effects of globalization on individual life courses and employment careers and the resulting changes in patterns of social inequality in modern societies. Empirically, we draw back to results from the international research project GLOBALIFE which studied the effects of globalization on modern life courses for the first time. The results show that the effects of globalization on individual life courses show marked differentiation with regards to specific life course phases: while especially the employment of mid-career men remained considerably stable under globalization, the careers of young adults, mid-career women as well as late-career workers underwent significant alterations. At the same time, results from the GLOABLIFE study indicate that the changes induced by globalization have not yet led to identical results at the national level. Globalization appears to be differentially filtered by deeply embedded and path-dependent national institutions. These “institutional packages” entail variable forms of labour market “flexibilisation” which themselves differentially shape patterns of social inequality in modern societies: While Scandinavian countries have largely succeeded in limiting an increase in social inequality under globalization through active public welfare engagement, globalization has led to a significant amplification of social inequalities in other regime types, either between labour market insiders and outsiders (in conservative and Southern European countries) or between individuals with different human capital resources (in liberal countries).     

Perspectives on Social Care Practice in Romania: Supporting the Development of Professional Learning and Practice

This paper examines the authors’ experiences of developingand delivering training for workers in social care servicesin Romania, through a European Union PHARE¹ funded project.The authors use their experiences to draw on the past and currentpractices of those social workers who were participants in thetraining and to explore their understanding of the emergingissues and themes for social work in Romania. There is alsoan exploration of the potential opportunities for the furtherdevelopment of professional social work learning and practicewithin Romania. The case is made that learning and developmentof social workers could be supported through the encouragementof participatory networks and ‘communities of practice’.     

TRANSFORMING DISCOURSE INTO PRACTICE: COMPUTERHYSTORIES AND DIGITAL CULTURES AROUND 1984

This paper discusses some theoretical approaches to the question of how culture, technologies and the social interact. These considerations result from the author' research in the genesis of digital cultures in the 1980s. The paper begins by outlining the author' research project, and then continues with a discussion of some of the most influential approaches in the cultural studies of technology.This article then presents a small sample of the author' analysis, which combines narratological and discourse analytical methods with practice-oriented cultural theories, such as those of Pierre Bourdieu, Régis Debray and Bruno Latour.     

The Uniqueness of the Child–Father Attachment Relationship: Fathers' Sensitive and Challenging Play as a Pivotal Variable in a 16-year Longitudinal Study

This longitudinal study of forty‐four families explored fathers’ as compared to mothers’ specific contribution to their children's attachment representation at ages 6, 10, and 16 years. In toddlerhood, fathers’ and mothers’ play sensitivity was evaluated with a new assessment, the sensitive and challenging interactive play scale (SCIP). Fathers’ SCIP scores were predicted by fathers’ caregiving quality during the first year, were highly consistent across 4 years, and were closely linked to the fathers’ own internal working model of attachment. Qualities of attachment as assessed in the Strange Situation to both parents were antecedents for children's attachment security in the Separation Anxiety Test at age 6. Fathers’ play sensitivity and infant–mother quality of attachment predicted children's internal working model of attachment at age 10, but not vice versa. Dimensions of adolescents’ attachment representations were predicted by fathers’ play sensitivity only. The results confirmed our main assumption that fathers’ play sensitivity is a better predictor of the child's long‐term attachment representation than the early infant–father security of attachment. The ecological validity of measuring fathers’ sensitive and challenging interactive play behavior as compared to infant proximity seeking in times of distress is highlighted. Findings are discussed with respect to a wider view on attachment in that both parents shape their children's psychological security but each in his or her unique way.     

Firm size and board diversity

This study seeks to understand the relation between firm size and supervisory board composition. Specifically, we ask if and how firm size influences occupational and international background diversity in supervisory boards. Relying on resource dependence theory and theories of organizational behavior, we hypothesize that board diversity with respect to directors’ occupational background will increase with firm size, while the relation between firm size and board diversity with respect to directors’ international background will be concave. Using archival data for supervisory board members of 151 German firms listed in the German stock exchange indices DAX, MDAX, SDAX and TecDAX for the business year 2005, we find empirical support for our hypotheses: Both, occupational and international background diversity increase with increasing firm size, but international background diversity does so at decreasing rates.
