How to dissolve fixed‐pie bias in negotiation? Social antecedents and the mediating effect of mental‐model adjustment

Fixed‐pie bias, defined as the erroneous belief that the other negotiation party's interest is directly opposite to one's own, has been a consistent hurdle that negotiators must overcome in their efforts to achieve optimal negotiation outcomes. In this study, we explore the underlying cognitive mechanism and the social antecedents of fixed‐pie bias reduction in negotiation. Using data from a negotiation simulation with 256 participants, we found that mental‐model adjustments made by negotiators could effectively decrease fixed‐pie bias. More interestingly, we also found that negotiators were less likely to reduce fixed‐pie bias when negotiating with an in‐group member than with an out‐group member but only under a high accountability condition. Finally, we found that mental‐model adjustment mediated the effects of the aforementioned social antecedents (in‐groupness and accountability) on reduced fixed‐pie bias. We discuss the theoretical and practical implications of these findings. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

Food sovereignty asserts the right of peoples to define and organize their own agricultural and food systems so as to meet local needs and so as to secure access to land, water and seed. A commitment to gender equity has been embedded in the food sovereignty concept from its earliest articulations. Some might wonder why gender justice should figure so prominently in a food movement. In this paper I review and augment the arguments for making gender equity a central component of food sovereignty. The most common argument is: if women constitute the majority of the world’s food producers, then agricultural policy is a women’s issue. And insofar as patriarchal social relations continue to dominate the globe, then changing agricultural policies will require explicit attention to gender injustice. I suggest that this is a good argument, but that an ecological feminist perspective can provide additional theoretical reasons for maintaining the centrality of gender justice in food sovereignty discourse. Moreover, ecological feminism can provide a robust theoretical framework that coheres a concept and movement with a wide set of concerns. My critique positions food sovereignty’s call to social justice as embedded in a truly radical re-thinking of dominant conceptual frameworks, and re-envisioning of political and ethical relations. 相似文献

This article summarizes the primary outcomes of an interdisciplinary workshop in 2010, sponsored by the U.S. National Science Foundation, focused on developing key questions and integrative themes for advancing the science of human–landscape systems. The workshop was a response to a grand challenge identified recently by the U.S. National Research Council (2010a)—“How will Earth’s surface evolve in the “Anthropocene?”—suggesting that new theories and methodological approaches are needed to tackle increasingly complex human–landscape interactions in the new era. A new science of human–landscape systems recognizes the interdependence of hydro-geomorphological, ecological, and human processes and functions. Advances within a range of disciplines spanning the physical, biological, and social sciences are therefore needed to contribute toward interdisciplinary research that lies at the heart of the science. Four integrative research themes were identified—thresholds/tipping points, time scales and time lags, spatial scales and boundaries, and feedback loops—serving as potential focal points around which theory can be built for human–landscape systems. Implementing the integrative themes requires that the research communities: (1) establish common metrics to describe and quantify human, biological, and geomorphological systems; (2) develop new ways to integrate diverse data and methods; and (3) focus on synthesis, generalization, and meta-analyses, as individual case studies continue to accumulate. Challenges to meeting these needs center on effective communication and collaboration across diverse disciplines spanning the natural and social scientific divide. Creating venues and mechanisms for sustained focused interdisciplinary collaborations, such as synthesis centers, becomes extraordinarily important for advancing the science. 相似文献

The mean vigilance of animals in a group often decreases as their group size increases, yet nothing is known about whether
there is individual variability in this relationship in species that change group sizes frequently, such as those that exhibit
fission–fusion social systems. We investigated variability in the relationship between group size and vigilance in the eastern
grey kangaroo (Macropus giganteus) by testing whether all individuals showed decreased vigilance with increased group size, as has been commonly assumed. We
carried out both behavioural observations of entire groups of kangaroos and focal observations of individually recognised
wild female kangaroos. As in other studies, we found a collective group-size effect on vigilance; however, individuals varied
in their vigilance patterns. The majority (57%) of the identified individual kangaroos did not show significant group-size
effects for any of the recorded measures of vigilance. The females that did not show a negative group-size effect were, on
average, more vigilant than those females that did show a group-size effect, but this difference was not significant. We propose
that some females exhibit higher levels of social vigilance than others, and that this social vigilance increases with group
size, cancelling out any group-size effect on anti-predator vigilance for those females. Our results therefore suggest that
only some prey individuals may gain anti-predator benefits by reducing their time spent scanning when in larger groups. The
large amount of variation that we found in the vigilance behaviour of individual kangaroos highlights the importance of collecting
and analysing vigilance data at the individual level, which requires individual recognition. 相似文献

The Estonian coastal waters serve as the south-eastern boundary of the regular distribution of the grey (Halichoerus grypus and ringed Phoca hispida) seal in the Baltic Sea. During the annual molt period in May–June (in the Estonian coastal waters), the stock size is estimated to be 1200–1500 grey seal individuals – that is, roughly 25% of the whole Baltic population. If we compare the chlororganic contents of seals in different areas the Baltic Sea, we can see that the northern part of the Gulf of Riga and Väinameri Sea is the reference area of the Baltic Sea. 相似文献

Game harvesting in South Africa generally leaves behind edible by-products, which could be a low-cost source of protein for poor people in rural areas. Seven professional and nine recreational hunters were interviewed, a game harvest and trophy hunt attended and literature reviewed, in order to describe the food value chain for game and ways in which edible by-products could be legally channelled into the human food chain, rather than being left in the field for scavengers. Practices of informal vendors (n = 51) were assessed using structured interviews, observation and microbiological analysis. In an experiment, inspected game by-products (shinbones from impala and springbok) were provided to eight informal traders for cooking at an informal market and microbiological analysis was done before and after preparation. The results showed that providing edible by-products to poor consumers appears to be culturally acceptable, affordable, accessible and safe. A crossover from formal to informal marketing is recommended as it would enhance traceability and safety of the product and minimise the risk of poaching. It is suggested that methods should be developed which make the distribution of edible by-products to vulnerable rural communities feasible. 相似文献
