Negative Effekte von Coaching und ihre Ursachen aus der Perspektive der Organisation

Negative effects of business-coaching and their causes have been barely addressed in research so far. In this qualitative pilot-study the perspective of organisations is being addressed for the first time. The most frequently stated negative effects were a too strong development of clients in the perception of the interviewees, a termination of the job by clients, a lack of sustainability of the results and an insufficient return on investment. As influencing factors e.?g. the attitude of the organisation towards coaching, imprecise clarification of coaching assignments, lack of motivation of the client or the working methods of coaches were reported.     

European Public Perceptions of Food Risk: Cross-National and Methodological Comparisons

This article presents a comparative study of public perceptions of food risk across 25 European member states. A secondary data analysis is conducted on a Eurobarometer survey fielded to nationally representative samples in 2005. The survey included closed questions as well as free associations to map risk perceptions. Taking a quantitative approach, we find that people in a majority of European countries express similar levels of concern about food risks. However, outside this majority a North-South divide is evident, with the Northern countries worrying less than the Southern countries. Multilevel modeling shows that cross-national differences in individual respondents' level of worry are in part attributable to shared country effects and to generalized risk sensitivity about a range of personal risks. On the underlying structure of food risk concerns, factor analysis points to three dimensions described by groupings of risks related to adulteration and contamination, health effects, and production and hygiene. A qualitative analysis of respondents' free associations about problems and risks with food identifies three major themes that are consistent with the quantitative results. However, the free associations also point toward greater cross-national diversity and to striking variations in the range and importance of food risks. Overall, the picture is of a public that frames food risks in a wider context of beliefs about the links between diet and health. We conclude with some implications for research on food risk perceptions in particular and risk perception studies in general.     

Inquiry

The following interview with Dr. Denise Johnston was conducted in October 2005. Dr. Johnston is a child development specialist and the founding director of the Center for Children of Incarcerated Parents, which has served more than 20,000 clients and is staffed almost exclusively by formerly incarcerated parents and children of prisoners.     

INQUIRY

The following interview with Awash Teklehaimanot was conducted in June 2005. Dr. Teklehaimanot is Director of the Malaria Program at Columbia University and a member of the Task Force on Malaria for the UN Millennium Project. He is a senior staff member of the World Health Organization (WHO) in Geneva, where he provides leadership in the development of the global Roll Back Malaria program. Dr. Teklehaimanot has extensive international experience in public health with particular focus on Africa. He provides technical support to malaria-endemic countries, coordinates a number of WHO-funded research activities in Africa, and spent several years as the director of Ethiopia's National Malaria Control Program. He is a professor of clinical epidemiology at Columbia University's Mailman School of Public Health, and has been lecturing at the Harvard School of Public Health since 1992.     

INQUIRY

The following interview with Gary Orfield was conducted in May 2004. Gary Orfield is a professor of education and social policy at the Graduate School of Education at Harvard University. He is the director of the Harvard Project on School Desegregation, and co‐director of the Harvard Civil Rights Project. Professor Orfield is the author of numerous books and publications, and has been consistently involved in government and court proceedings dealing with issues related to his research. He has been called to testify in civil rights suits by the US Department of Justice and many civil rights, legal services, and educational organizations. In 1997, Professor Orfield was awarded the American Political Science Association's Charles Merriam Award for his “contribution to the art of government through the application of social science research.”     

Optimal designs for non-competitive enzyme inhibition kinetic models

In this paper, we present a new method for determining optimal designs for enzyme inhibition kinetic models, which are used to model the influence of the concentration of a substrate and an inhibition on the velocity of a reaction. The approach uses a nonlinear transformation of the vector of predictors such that the model in the new coordinates is given by an incomplete response surface model. Although there exist no explicit solutions of the optimal design problem for incomplete response surface models so far, the corresponding design problem in the new coordinates is substantially more transparent, such that explicit or numerical solutions can be determined more easily. The designs for the original problem can finally be found by an inverse transformation of the optimal designs determined for the response surface model. We illustrate the method determining explicit solutions for the D-optimal design and for the optimal design problem for estimating the individual coefficients in a non-competitive enzyme inhibition kinetic model.     

Attitudes Toward Intergenerational Redistribution in the Welfare State

Which motivations explain attitudes toward intergenerational redistribution? This study presents two perspectives. The first one is demographic aging where individuals’ attitudes are influenced by short- and long-term self-interest. The second perspective is socialization into a certain institutional context where people internalize the reciprocity and the deservingness norms. Besides investigating the impact of these motivations, the empirical analysis assesses their relative importance for explaining attitudes toward intergenerational redistribution. The ordinary least-squares regression draws on data of the “Attitudes Toward The Welfare State” survey that was conducted in 2008 in Germany. The study investigates the working age group’s attitude toward relative governmental spending for older people. The empirical analysis yields that people are motivated by long-term self-interest and hold the state responsible to protect them from the perceived future risk of old-age poverty. Also, norms of reciprocity and of deservingness are important to support intergenerational redistribution, whereas the latter seems to be the relatively most important motivation. We can take this as a sign of intergenerational cohesion that is relevant against the background of accelerating demographic aging and resulting pressure on institutions of intergenerational redistribution.
