Paternal inheritance of growth in fish pursuing alternative reproductive tactics

In species with indeterminate growth, age-related size variation of reproductive competitors within each sex is often high. This selects for divergence in reproductive tactics of same-sex competitors, particularly in males. Where alternative tactics are fixed for life, the causality of tactic choice is often unclear. In the African cichlid Lamprologus callipterus, large nest males collect and present empty snail shells to females that use these shells for egg deposition and brood care. Small dwarf males attempt to fertilize eggs by entering shells in which females are spawning. The bourgeois nest males exceed parasitic dwarf males in size by nearly two orders of magnitude, which is likely to result from greatly diverging growth patterns. Here, we ask whether growth patterns are heritable in this species, or whether and to which extent they are determined by environmental factors. Standardized breeding experiments using unrelated offspring and maternal half-sibs revealed highly divergent growth patterns of male young sired by nest or dwarf males, whereas the growth of female offspring of both male types did not differ. As expected, food had a significant modifying effect on growth, but neither the quantity of breeding substrate in the environment nor ambient temperature affected growth. None of the environmental factors tested influenced the choice of male life histories. We conclude that in L. callipterus growth rates of bourgeois and parasitic males are paternally inherited, and that male and female growth is phenotypically plastic to only a small degree.

Collecting Societies - Not Yet 'Six Feet Under'

Despite ubiquitous digitisation and the advent of Digital Rights Management Systems, it seems that collecting societies are not quite yet six feet under. Even in a world of rapid technological developments collecting societies will keep providing services to authors, users and the public facilitating the management of rights and performing additionally certain important social and cultural functions. However, agreeing on the future of collecting societies and on the particular design of both individual and collective rights administration is not an easy task and the opinions of the major stakeholders are diverse and often conflicting.

Was hat Max Weber mit Kātib Čelebi zu tun? Ein Annäherungsversuch an Gottfried Hagen

This article responds to Gottfried Hagen’s extensive review (see Der Islam 2/2013) of my book Islamische Verantwortungsethik im 17. Jahrhundert. Ein weberianisches Verständnis der Handlungsvorstellungen Kātib Čelebis (1609– 1657). Whilst I benefitted greatly from some of Hagen’s critical remarks and his- torical elucidations, his review not only misstates crucial passages of my book but also largely disregards its main objective, which is to develop a systematic model for understanding Kātib Čelebi’s ethical stance. Besides reiterating cru- cial arguments ignored and rectifying central aspects misrepresented in Hagen’s review, I here ask how the more fundamental misunderstandings – exceeding differences in theoretical positions or empirical observations – between the au- thor’s intentions and the reviewer’s reception may be explained. Gottfried Hagen’s historiographical perspective on Kātib Čelebi diverges from my sociological take on the same subject matter to the extent that both perspectives are struggling to enter into dialogue. Such dialogue, however, remains highly desirable so as to complement a historical reconstruction of Kātib Čelebi’s life and times with a systematic, theoretically grounded understanding of his views.

Passionate thinkers feel better: Self-control capacity as mediator of the relationship between need for cognition and affective adjustment

The present study tested a possible explanation for the positive relationship between the motivation to engage in cognitive endeavors (need for cognition, NFC) and indicators of affective adjustment (e.g., higher self-esteem, lower depression) that has been demonstrated in previous studies. We suggest that dispositional self-control capacity mediates this relationship, since NFC has been found to be related to self-control capacity, and self-control capacity is crucial for adjustment. NFC, dispositional self-control capacity, self-esteem, habitual depressive mood, and tendency to respond in a socially desirable manner were measured among 150 university students via self-report. Regression analyses and Sobel tests revealed that self-control capacity was a potential mediator of the positive relationship between NFC and affective adjustment. The findings were robust in terms of social desirability.

Holland's secondary constructs of vocational interests and career choice readiness of secondary students

The study examined the relationship between the secondary constructs of Holland’s (1997) theory of vocational interests and career choice readiness [career maturity] attitudes with 358 Swiss secondary students. The hypothesis was tested that the secondary constructs consistency, coherence, differentiation, and congruence are measures for the degree of vocational interest development. Thus, they should belong to the content domain in career choice readiness and should show meaningful relations to career choice readiness attitudes. The hypothesis was confirmed for congruence, coherence, and differentiation. Interest profile consistency showed no relation to career choice readiness attitudes. Vocational identity emerged as a direct measure for career choice readiness attitudes. Realism of career aspirations was related to career choice readiness attitudes and coherence of career aspirations. Profile elevation was positively connected to more career planning and career exploration. Differences between gender, ethnicity, and school-types are presented. Implications for career counselling and assessment practice are discussed.

The construct of career success: measurement issues and an empirical example

The aim of the present paper is twofold. We first give an overview of the multi-faceted construct of career success with its “objective” (real attainments) and “subjective” (perceived attainments) components and with the different methodologies measuring them (“subjectivist” vs. “objectivist” approaches). We also discuss the relationship between the different components of career success as revealed in the literature. Our second aim is to show that the interrelationship between the different facets of career success varies with the employment context. We analyze subjective and objective career success measures collected from professionals working either in the private sector, in the public sector, or that are self-employed. Our findings show that objective success and subjective success are more closely related in the private and self-employment sectors than in the public sector. Moreover, the interrelationship between objective and subjective success varies with the specific subjective success measure chosen. It is stronger for an “other-referent” subjective success measure than for a “self-referent” subjective success measure. Conclusions regarding the measurement of career success as well as regarding the relevance of subjective success for studying occupational careers are drawn.

Protean and boundaryless career attitudes: relationships with subjective and objective career success

The protean and boundaryless career attitudes have gained special attention during the past years. Aprotean career attitude implies that aperson strives towards adevelopmental progression and self-fulfillment; aboundaryless career attitude is characterized by ahigh physical and/or psychological mobility. The aim of the present paper is twofold: First, we want to empirically investigate the relationship between protean and boundaryless career attitudes and subjective (i.e., career satisfaction and success in comparison with colleagues) and objective (i.e., promotions and salary) career success. Second, we want to integrate research on protean and boundaryless career attitudes with research on predictors of career success. We analyze the career attitudes-career success relationship with asample of 116 professionals. Our findings suggest that components of the protean career attitude are rather more related with subjective career success and that components of the boundaryless career attitude are more related with objective career success. Conclusions regarding the relevance of career attitudes for career success are drawn.
