Transnationalization of a Recruitment Regime: Skilled Migration to Japan

Japan, facing a demographic decline and challenges by companies and universities to internationalize, has opened its doors to skilled migration. Focussing initially on a two‐step student migration model, Japanese companies are now recruiting young graduates from overseas universities, mainly in Asia. We argue that, with the help of brokers, the domestic recruitment regime (a set of particular employment practices) has been transnationalized. Based on interviews with stakeholders and discussing international recruitment fairs as the site of engagement, we present first evidence that the activities of brokers have the potential to change attitudes towards employability among overseas universities and their students. We also find that this development compromises the original diversity objectives of Japanese employers and point to a lack of rules of engagement for brokers operating across national borders.     

Transforming child and family services in urban communities in South Africa: lessons from the South

Post‐apartheid, South African agencies have been required to shift their services in fundamental ways, including offering services in previously un‐resourced areas, honouring the rights of children and families, ensuring that users, staff and governing bodies are representative of the population and providing developmental social welfare services in place of child protection‐oriented interventions only. A study of urban South African child welfare agencies provides insight into the complex task of managing and leading change. In view of overloaded change agenda and resource constraints, managers focused on effecting incremental change and prioritized the most ‘rewarding’ change efforts. Transforming practice towards a developmental approach was less successful. Structural interventions were also not prioritized. Child welfare agencies internationally face demands to transform in response to the effects of local change and globalization. The study's insights might resonate with agencies working for change in other societal contexts.     

School enrolment and mothers’ labor supply: evidence from a regression discontinuity approach

We analyze the impact on maternal employment of a universal school reform in Norway which lowered the school starting age from seven to six. We use a regression discontinuity approach exploiting exogenous variation in the compulsory school enrollment rule caused by the reform. Our results reveal positive short-term effects on labor supply (approximately five percentage points) and on earnings (about 12600/1350 NOK/Euro). Subgroup analyses show that the positive effects are much stronger for mothers with low wage potential, a group of mothers that were less likely to use formal childcare prior to the reform. The positive effects for this subgroup of mothers suggest that expanding child-care can be an effective tool for increasing labor supply of mothers who previously had relatively low labor market earnings potential.     

Effektive Führung heterogener Teams

This article in the journal “Gruppe. Organisation. Interaktion. (GIO)” analyzes theoretical and empirical findings of international research on the role of leadership in diverse teams. While practitioners often tend to expect primarily positive effects of team diversity, research has revealed both positive and negative consequences on team performance. Thereby, realizing positive outcomes of diversity appears to depend on additional boundary conditions; among these, leadership is often considered to be crucial. According to our analysis of the literature, established leadership styles (e.?g., transformational leadership, LMX, leader consideration) may contribute to increased performance of diverse teams. In addition, they will be most effective when leaders perceive and treat their followers as individuals rather than as members of a (sub-)group and when they carefully adjust their behavior to the most critical diversity attribute in the team. Based on these results, we provide practical implications for leadership in diverse teams and discuss how adequate leadership skills can be systematically developed in organizations.     

Wenn die Unterrichtssprache gewaltig wird Gefährdungen der Lehrer-Schüler-Beziehung durch sprachgewaltige Lehrerinnen und Lehrer

Good teachers who initiate learning effective lessons can be characterized within the meaning of the authoritative parenting by consequent leadership, warmth and cordiality. Especially the language of the teachers plays an important part in every discussion during the lesson and in every feedback concerning the learning and performance level of individual pupils or groups. Nonetheless, the teacher’s language is neglected in modern educational research. This article has a closer look on the language used in the classroom and its relevance for a learning efficient working atmosphere inside the learning group. Moreover, it presents older and new empirical results which have been developed in an interdisciplinary effort towards this subject. The article leads to concrete suggestions for a higher linguistic professionalism of teachers in their daily job.     

Needs of ergonomic design at control units in production industries

During the last decades, an increasing use of innovative technologies in manufacturing areas was monitored. A huge amount of physical workload was replaced by the change from conventional machine tools to computer-controlled units. CNC systems spread in current production processes. Because of this, machine operators today mostly have an observational function. This caused increasing of static work (e.g., standing, sitting) and cognitive demands (e.g., process observation). Machine operators have a high responsibility, because mistakes may lead to human injuries as well as to product losses - and in consequence may lead to high monetary losses (for the company) as well. Being usable often means for a CNC machine being efficient. An intuitive usability and an ergonomic organization of CNC workplaces can be an essential basis to reduce the risk of failures in operation as well as physical complaints (e.g. pain or diseases because of bad body posture during work). In contrast to conventional machines, CNC machines are equipped both with hardware and software. An intuitive and clear-sighted operating of CNC systems is a requirement for quick learning of new systems. Within this study, a survey was carried out among trainees learning the operation of CNC machines.     

Productivity of Older Workers: Perceptions of Employers and Employees

What determines the perceived productivity of the older worker and how does this perception compare to the perception of the productivity of the younger worker? In this study we present evidence based on data from Dutch employers and employees. Productivity perceptions are affected by one's age and one's position in the hierarchy. The young favor the young, the old favor the old, and employers value the productivity of workers less than employees do. However, there are also remarkable similarities across employers and employees. By distinguishing the various dimensions that underlie the productivity of younger and older workers, we tested whether soft qualities and abilities—e.g., reliability and commitment—are just as important as hard qualities—cognitive and physically based skills—in the eyes of both employers and employees. It appears that both employers and employees, young and old, view hard skills as far more important than soft skills.     

Volatility and GMM — Monte Carlo studies and empirical estimations

In this article we examine small sample properties of a generalized method of moments (GMM) estimation using Monte Carlo simulations. We assume that the generated time series describe the stochastic variance rate of a stock index. we use a mean reverting square-root process to simulate the dynamics of this instantaneous variance rate. The time series obtained are used to estimate the parameters of the assumed variance rate process by applying GMM. Our results are described and compared to estimates from empirical data which consist of volatility as well as daily volume data of the German stock market. One of our main findings is that estimates of the mean reverting parameter that are not significantly different from zero do not necessarily imply a rejection of the hypothesis of a mean reverting behavior of the underlying stochastic process.     

Choosing appropriate covariance matrices in a nonparametric analysis of factorials in block designs

The standard nonparametric, rank-based approach to the analysis of dependent data from factorial designs is based on an estimated unstructured (UN) variance–covariance matrix, but the large number of variance–covariance terms in many designs can seriously affect test performance. In a simulation study for a factorial arranged in blocks, we compared estimates of type-I error probability and power based on the UN structure with the estimates obtained with a more parsimonious heterogeneous-compound-symmetry structure (CSH). Although tests based on the UN structure were anti-conservative with small number of factor levels, especially with four or six blocks, they became conservative at higher number of factor levels. Tests based on the CSH structure were anti-conservative, and results did not depend on the number of factor levels. When both tests were anti-conservative, tests based on the CSH structure were less so. Although use of the CSH structure is concluded to be more suitable than use of the UN structure for the small number of blocks typical in agricultural experiments, results suggest that further improvement of test statistics is needed for such situations.
