Social Identity Development

Entering a new group provides the potential of forming a new social identity. Starting from self-regulation models, we propose that goals (e.g., internal motivation to enter the group), strategies (e.g., approach and avoidance strategies), and events (e.g., the group’s response) affect the development of the social self. In two studies we manipulated the group’s response (acceptance vs. rejection) and assessed internal motivation as well as approach and avoidance strategies. It was expected, and we found, that when newcomers are accepted, their use of approach strategies (but not avoidance strategies) facilitates social identification. In line with self-completion theory, for highly internally motivated individuals approach strategies facilitated social identification even upon rejection. The results underline the active role of newcomers in their social identity development.

Mixed Plantation

Since the present climate in Switzerland includes abundant rainfall, the climatic changes should not present any serious danger of the ground drying out. In fact, higher precipitation levels are predicted. So it would seem that climate is likely to become more luxuriant rather than more dry. These conditions – together with the entry of nutrients with the rainfall – favour the growth of ash and maple but not of oak. Even with an increase in stressful dry summer periods, a consideration of the broad areas of distribution of indigenous species shows they possess a sufficiently great adaptability. Research into the effects of physiological stress on fir trees from different provenances shows in particular that those with local origins are better adapted to the habitat than those from elsewhere. The danger of an increase in storms should be countered by strategies aimed at increased resistance – through mixed plantation regulation and thinning out – rather than avoidance strategies. Ecoforestry is basically well armed for this task. It should be even more orientated towards the adaptability and resilience of forests.

ABSTRACT This study examines (1) whether network ties help explain variation in tax avoidance, and (2) how the relation between network ties and tax avoidance varies depending on the nature and context of those ties. We posit that information on a range of tax-avoidance strategies is shared among firms through their social network connections. Using board interlocks to proxy for these connections, we find that firms with greater board ties to low-tax firms have lower cash ETRs themselves. Ties to low-tax firms are more influential when the focal firm and its network partner are operationally and strategically similar, as are ties created by executive directors. Board ties to low-tax firms are also more influential when the focal firm and its network partner engage the same local auditor. Overall, our results suggest that the influence of firms' network ties on their tax-avoidance behavior depends on the character of those ties.

The Relationship

The author lays a blueprint for distinctions between legal and moral rules and socially accepted behavior, situations in which these distinctions set different standards of conduct, and the relationship among them. Several of the more common paradigms of cultural property disputes are then fit into the patterns of legal and moral rules and obligations, thus establishing a framework for the discussion of how to evaluate ethical or moral behaviors in varying circumstances. The author also considers the relevance of deontological and consequentialist arguments for the return of cultural property, as well as avoidance strategies by which a country of origin can make a claim for restitution while ignoring the long-term questions of the legitimacy, power, and responsibilities of national governments. The author concludes by emphasizing the difficulties in basing arguments concerning cultural property on moral evaluations and conclusions.

Parallel Features

A new approach called bioinspired engineering of exploration systems (BEES) and its value for solving pressing NASA and DoD needs are described. Insects (for example honeybees and dragonflies) cope remarkably well with their world, despite possessing a brain containing less than 0.01% as many neurons as the human brain. Although most insects have immobile eyes with fixed focus optics and lack stereo vision, they use a number of ingenious, computationally simple strategies for perceiving their world in three dimensions and navigating successfully within it. We are distilling selected insect-inspired strategies to obtain novel solutions for navigation, hazard avoidance, altitude hold, stable flight, terrain following, and gentle deployment of payload. Such functionality provides potential solutions for future autonomous robotic space and planetary explorers. A BEES approach to developing lightweight low-power autonomous flight systems should be useful for flight control of such biomorphic flyers for both NASA and DoD needs. Recent biological studies of mammalian retinas confirm that representations of multiple features of the visual world are systematically parsed and processed in parallel. Features are mapped to a stack of cellular strata within the retina. Each of these representations can be efficiently modeled in semiconductor cellular nonlinear network (CNN) chips. We describe recent breakthroughs in exploring the feasibility of the unique blending of insect strategies of navigation with mammalian visual search, pattern recognition, and image understanding into hybrid biomorphic flyers for future planetary and terrestrial applications. We describe a few future mission scenarios for Mars exploration, uniquely enabled by these newly developed biomorphic flyers.
