Coaching und Internet? Chancen und Grenzen des Internets für Coaches und Klienten

Coaching and internet? Chances and limitations of the internet to coaches and clientsThis article describes potentials and limitations of Internet-based coaching and counseling. It focuses on the capabilities of the Internet as a medium of information and communication and its significance for coaches, clients and newbies. Some suggestions are given on how coaches and clients could use the Internet for working purposes. The necessity to analyze and integrate important medium-specific, individual-specific and interpersonal factors should be kept in mind. This follows the fact that they function together in a dynamic way, as the media-ecologic model of Döring (2003) postulates.     

Das Karriereplateau

The career-plateau as challenge to enterprises, employees and consultantsThe authors intend to link life-span-psychology to career-research in order to make understand the phenomenon of career-plateau and how individuals and organisations can deal with it. People take stock in the middle of their lives and assess their personal or professional targets. This process often relates to a personal crisis, especially when the success rate of a job is an important part of the self-concept and hierarchical development has stopped simultaneously. Nevertheless, the desire for a career continues to exist. On top of that what makes it even harder is that the individual has to work at least 20 more years because of demographic reasons. We assume that the way how to manage this crisis has a big influence on performance motivation and that life-span-orientated management development can help the individual to overcome the crisis or even prevent it.     

Coaching von Schlaganfallpatienten Ein integratives Beratungs- und Trainingskonzept

Coaching of patients after apoplexy — an integrative model of counselling and trainingIn contrast to common assessments of medical professionals, improvements in rehabilitation of patients after an apoplexy are possible even after a greater time interval. The progresses are small, but they improve gradually the quality of life of the patients. The author presents an integrative model of counselling and training for this clientele, in order to accompany the way of the patients to a successful professional rehabilitation and to a new conduct of life.     

Educational selectivity in U.S. Immigration: How do immigrants compare to those left behind?

Current immigration research has revealed little about how immigrants compare to those who do not migrate. Although most scholars agree that migrants are not random samples of their home countries' populations, the direction and degree of educational selectivity is not fully understood. This study of 32 U.S. immigrant groups found that although nearly all immigrants are more educated than those who remain in their home countries, immigrants vary substantially in their degree of selectivity, depending upon the origin country and the timing of migration. Uncovering patterns of immigrant selectivity reveals the fallacy in attributing immigrants' characteristics to national groups as a whole and may help explain socioeconomic differences among immigrant groups in the United States.     

Parental divorce and subsequent disadvantage: A cross-cohort comparison

Although many studies have examined the link between parental divorce and subsequent well-being, some theories of the effects of divorce suggest that the negative associations should have declined over time. However, few studies have examined the extent to which the associations have remained stable over time. Using data from two British cohorts, we analyzed both shorter- and longer-term outcomes of children who experienced parental divorce and the extent to which the associations have changed over time. Estimating similar models for both cohorts, we found little evidence of any change in the size of the relationship as divorce became more commonplace.     

Familial obesity as a proxy for omitted variables in the obesity-mortality relationship

In a conventional survival analysis of a sample of the U.S. population in 1971-1974, the association between mortality and obesity is compared with the analogous risk from the presence of an obese person in a household. The two factors have similar risk profiles, with a hazard ratio of 1.44 for nonmorbid obesity and 1.48 for nonmorbid familial obesity in one sample. If "familial obesity" cannot directly affect personal longevity, and if shared factors determine both personal and familial obesity, the mortality risk of family and actual personal obesity is similarly overstated. This false positive in the estimated risk arises from correlations among obesity and unobserved environmental, behavioral, or genetic factors.

Reading “Monosexual”

This essay interrogates the meanings, uses, and implications of the emergent U.S./U.K. bisexual community’s adoption of the term “monosexual” to define non-bisexuals. The authors provide a historical and theoretical context for the term, explicitly linking its oppositional rhetoric to that coined by other recent identity movements, and to that inherent in psychological and psychoanalytical models of identity development. The authors further emphasize their own personal and political responses to and dislike of the term. The essay examines the inconsistencies implicit in the meanings and uses of the term, highlighting the differences between sexual behavior and sexual identity. The unsuitability of the monosexual/bisexual paradigm for a bisexual movement that always overlaps—theoretically, politically, and personally—with other movements is also discussed. The authors conclude by stressing the importance of developing language that expresses the complexity of sexual identity and divergent political affiliation.     

Determinants and consequences of internal control in firms: a contingency theory based analysis

In order to ensure the efficiency and effectiveness of activities, reliability of information and compliance with applicable laws, firms demand adequate internal control. However, several frameworks (COSO, CoCo etc.) assume that the need for internal control varies according to a firm’s characteristics. This concurs with contingency theory, which claims that each organization has to choose the most suitable control system by taking into account contingency characteristics. This study examines which contingency characteristics firms choose to adapt their internal control structure and whether it results in a more favorable assessment of the effectiveness of control by the management. While the components of internal control have been examined individually in the control literature, this paper attempts to shed light on internal control and place it in a broader context. The results, derived from a web-based survey of 741 Finnish firms, indicate that firms adapt their internal control structure to deal with environmental uncertainty and to achieve observed control effectiveness. Also the strategy has statistically significant effects on internal control structure.     

Subhypergraph counts in extremal and random hypergraphs and the fractional <Emphasis Type="Italic">q</Emphasis>-independence

We study the extremal parameter N(n,m,H) which is the largest number of copies of a hypergraph H that can be formed of at most n vertices and m edges. Generalizing previous work of Alon (Isr. J. Math. 38:116–130, 1981), Friedgut and Kahn (Isr. J. Math. 105:251–256, 1998) and Janson, Oleszkiewicz and the third author (Isr. J. Math. 142:61–92, 2004), we obtain an asymptotic formula for N(n,m,H) which is strongly related to the solution α _q (H) of a linear programming problem, called here the fractional q-independence number of H. We observe that α _q (H) is a piecewise linear function of q and determine it explicitly for some ranges of q and some classes of H. As an application, we derive exponential bounds on the upper tail of the distribution of the number of copies of H in a random hypergraph.
