Field study of age-differentiated strain for assembly line workers in the automotive industry

A field study in an automotive supply industry company was conducted to explore age-differentiated strain of assembly line workers. Subjective and objective data from 23 female workers aged between 27 and 57 years were collected at the workplace belt buckle assembly during morning shifts. Subjects with medication or chronic diseases affecting heart rate and breath rate were excluded. For subjective data generation different questionnaires were used. Before the Work Ability Index and the Munich Chronotype Questionnaire were completed by the subjects. Short questionnaires (strain-ratings, NASA-TLX) directly at begin and end of the work were used for obtaining shift-related data. During the whole shift (6 a.m. - 2.45 p.m.) bodily functions were logged with a wireless chest strap. In addition, the motion of the hand-arm-system was recorded for 30 times, 3 minutes each after a fixed time-schedule. First results show that younger subjects need significant less time for assembly (mean = 14.940 s) compared to older subjects (mean = 17.040 s; t(472.026) = -9.278 , p < 0.01).     

Sind türkischstämmige Kinder beim Schulstart im Nachteil?

This article analyses the effect of a Turkish migration background on the risk of delayed school entry. Besides the social background, we control general and host country specific individual skill levels of the child. We assume that children’s individual skills can affect the school entry decision both directly and indirectly. We use data of the longitudinal project “Preschool education and educational careers among migrant children” (German acronym ESKOM VG). About 500 German parents and 500 Turkish-origin parents were interviewed in this study. Standardized developmental tests were conducted with the children in various domains. We find that the Turkish migration background does not have an independent effect on the probability of delayed school entry when the social background and individual skills are controlled. We furthermore disentangle the indirect effect of the Turkish migration background using the khb method. The results indicate that mathematic skills and cultural knowledge have the largest contribution on this indirect effect.

Environment, transnational labor migration, and gender: case studies from southern Yucatán, Mexico and Vermont, USA

Gender shapes the migration–environment association in both origin and destination communities. Using quantitative and qualitative data, we juxtapose these gender dimensions for a labor migrant-sending location of Mexico’s southern Yucatán with those for a labor migrant-receiving location in Vermont (USA). We illustrate how in the southern Yucatán, circular transnational migration alters pasture, maize and chili production in a peasant field–forest system. Gender norms condition the land-use decisions of migratory households to keep women out of agricultural fields, but in turn may be modified in unexpected ways. With men’s migration, more women assume aspects of land management, including in decision-making and supervision of hired farm labor. In comparison, in Vermont a largely male migrant labor force helps maintain an idealized, pastoral landscape with gender deeply embedded in how that labor is constructed and managed.     

Firm age dynamics and causes of corporate bankruptcy: age dependent explanations for business failure

Personality traits and knowledge sharing

In this paper, we describe an empirical study that relates three personality traits (agreeableness, conscientiousness and openness) to knowledge sharing. In the existing literature considerable attention has been paid to managerial influences on knowledge sharing, technological support through information and communication systems, or individual characteristics like motivation or the perception of conflict of interest or vulnerability. Instead we concentrate on the role that personal dispositions play in individual’s knowledge sharing behavior. By means of structural equation modeling with PLS, we discover significant correlations between the personality traits and knowledge sharing within teams of an engineering company. Our results clearly contribute to the existing literature, as they offer empirical evidence of the impact of enduring individual characteristics on knowledge sharing.     

Anwendungsorientierte Forschung und der Wandel der Wissensordnung zu Geschlecht: Konzeptionelle Annäherungen

First, the article is a speech for theoretical ambitious and applied oriented gender research. However, the transfer between scientific knowledge and praxis-oriented knowledge is an independent step, which might be based on gender trainings and gender expertise. Second, the complex processes of knowledge transfer and communication and its impacts on the scientific order of knowledge in the gender arena forms part of the debate. The paper discusses these issues and challenges for scientific gender knowledge from the perspective of gender studies and the sociology of professions, scientific discourses, and sociology of science.     

Trust in management and knowledge sharing: The mediating effects of fear and knowledge documentation

Knowledge sharing within and between teams is of vital importance for organizations. The influence of interpersonal trust in general and trust in management in particular on knowledge sharing is evident. However, it is not clear how the relationship between interpersonal trust and knowledge sharing works. This study provides a better understanding of that relationship by demonstrating that fear of losing one's unique value and knowledge documentation have a mediating effect on the relationship between trust in management and knowledge sharing. Specifically, trust in management increases knowledge sharing through reducing fear of losing one's unique value and improving willingness to document knowledge. These findings have important implications at both a managerial and theoretical level. For managers, this paper emphasizes the individual's central role in the knowledge sharing process in terms of knowledge documentation and fear of losing one's unique value. On the theoretical level, this study provides empirical evidence for two mechanisms that help explain the effect of trust in management on knowledge sharing. In future research, this study could be extended to include other psychosocial phenomena that enable knowledge sharing in organizations.
