Between-Population Outbreeding Affects Plant Defence

Between-population crosses may replenish genetic variation of populations, but may also result in outbreeding depression. Apart from direct effects on plant fitness, these outbreeding effects can also alter plant-herbivore interactions by influencing plant tolerance and resistance to herbivory. We investigated effects of experimental within- and between-population outbreeding on herbivore resistance, tolerance and plant fitness using plants from 13 to 19 Lychnis flos-cuculi populations. We found no evidence for outbreeding depression in resistance reflected by the amount of leaf area consumed. However, herbivore performance was greater when fed on plants from between-population compared to within-population crosses. This can reflect outbreeding depression in resistance and/or outbreeding effects on plant quality for the herbivores. The effects of type of cross on the relationship between herbivore damage and plant fitness varied among populations. This demonstrates how between-population outbreeding effects on tolerance range from outbreeding depression to outbreeding benefits among plant populations. Finally, herbivore damage strengthened the observed outbreeding effects on plant fitness in several populations. These results raise novel considerations on the impact of outbreeding on the joint evolution of resistance and tolerance, and on the evolution of multiple defence strategies

Socio-cognitive determinants of consumers’ support for the fair trade movement

Despite the reasonable explanatory power of existing models of consumers’ ethical decision making, a large part of the process remains unexplained. This article draws on previous research and proposes an integrated model that includes measures of the theory of planned behavior, personal norms, self-identity, neutralization, past experience, and attitudinal ambivalence. We postulate and test a variety of direct and moderating effects in the context of a large survey with a representative sample of the U.K. population. Overall, the resulting model represents an empirically robust and holistic attempt to identify the most important determinants of consumers’ support for the fair-trade movement. Implications and avenues for further research are discussed

Organization and management in the midst of societal transformation: The People's Republic of China

Twenty-five years of economic reform has propelled China to the center of the world's economic stage. Based on current trends, in the foreseeable future China is likely to become the largest economy in the world. China's dramatic growth may be envied by other developing economies, but for management scholars it presents an exciting intellectual puzzle. In this paper we describe the empirical context of China today, review contemporary research on Chinese management and organizations, and describe the nine papers in this special issue of Organization Science. The papers provide a close examination of how massive corporate transformation in China has influenced interfirm relationships, affected opportunity structures and social processes, and modified individual behaviors within firms. We identify the many paradoxes in this intellectual terrain and present a guide to the challenging research agenda ahead. We recommend that scholars of organizations think deeply about China as a context and consider China as an empirical setting where the boundaries of existing knowledge on organizations can be extended
