Cooperation and competition are often viewed as incompatible, antagonistic forces, thus are operationalized as two extremes on a continuum. However, they can coexist and even enable each other, thus may be operationalized as orthogonal constructs. We address this contradictory phenomenon by developing a more granular view of the cooperation–competition paradox. Building on interdisciplinary research, we develop a three-dimensional model of relational space (fairness–opportunism, sharing–control, and engagement–rivalry), providing a novel tool with which to investigate the paradoxical interplay between cooperation and competition through eight operationalizable configurations. Using fuzzy-set qualitative comparative analysis (fsQCA), we test our model by assessing how different configurations of interfirm relationships influence the short- and long-term success of a sample of 217 firms. Our findings show that only two of the eight possible relational configurations are associated with firm success, one in both the long and short term, and the other in the short term only.  相似文献

This paper explores vulnerable relational knowing, and in it we open up our own embodied habits and experiences as feminist academics. We discuss how displaying our academic bodies as naked, both symbolically and physically, enhances and appreciates—instead of hiding—vulnerability. We also discuss how our academic bodies entangle with a range of more-than-human creatures and material surroundings to highlight the multispecies and material nature of vulnerable relational knowing. Two detailed stories, “Intimate sharing of academic knowledge: A recumbent study circle” and “Keropirtti: A place and space to work differently” provide unique examples of the enactment of alternative ways of working in academia, and their analysis demonstrates the potential of vulnerability for embodied relational knowing in academia, which has, to date, been commonly analyzed in the context of writing.  相似文献

迄今,为解决多属性偏好关联决策属性集容量判断指数复杂性难题所提出的λ模糊测度模式与k-可加模糊测度模式,以及建构在它们之上的属性集容量确定的推算模型,尚存在着适用性差的技术不足。为此,以平衡容量判断的可操作性和容量推算的准确性为视角,提出了一种新容量测度模式,即关于容量判断与推算的夹挤式测度模式,并在此基础上通过引入决策者较易判断给出的容量序信息构建了相应的容量推算模型。基于数值模拟的对比分析表明:新模式不仅在应用可行性上高于k-可加模糊测度模式,而且从容量推算的准确性上看也明显优于λ模糊测度模式和k-可加模糊测度模式,因而对实际决策具有更强的适用性。  相似文献

当代知识论越来越重视认知价值的研究,但从认知价值角度去重新思考传统怀疑主义问题的研究却很少。历史上的怀疑主义者既认为我们无法拥有任何知识,又主张我们应该悬置判断。因此,他们不仅预设了一个高的知识标准,而且预设了一个价值标准:任何达不到知识标准的认知状态都是没有认知价值的。但这个价值标准是错误的,所以我们即使无法达到怀疑主义者所设定的知识标准,也不必悬置判断。假设怀疑主义者认为我们无法拥有任何知识,同时认可“有些达不到知识标准的认知状态也有认知价值”,那么怀疑主义就没有很大的威胁性,因为即使我们无法获取知识,也可以获得具有认知价值的东西,取得认知进步。此外,摩尔主义、语境主义、溯因主义这几种对怀疑主义的主要回应是否成功,最终都依赖于对认知价值的讨论。  相似文献

Background

The rates of breastfeeding worldwide are slowly improving since 1996. Europe is still trailing behind the global breastfeeding incidence and prevalence rates. Thus, breastfeeding promotion, protection, prolongation and support have become an important challenge as breastfeeding sharply decreases in the first six months of life.

Objectives

The aim of this project is to determine, assess and identify the real impact of breastfeeding support networks in Murcia (Spain).

Methods

After searching unsuccessfully for a validated questionnaire, a specific one was developed and validated for measuring the impact of formal and informal support networks through five dimensions: satisfaction, consultation, experience, problems and support. The questionnaire was provided to 500 mothers with experience in breastfeeding, who brought their children to baby paediatricians between 2 June and 27 November 2014. Upon completion of the survey and fieldwork, a detailed statistical analysis was conducted.

Results

The degree of satisfaction perceived by the users of the services of support breastfeeding networks is remarkable. In addition, mothers who clarified their doubts and discussed their problems with health professionals and/or breastfeeding support networks were more likely to breastfeed for a longer duration compared to those who did not (p = 0.005). Furthermore, mothers who sought support in breastfeeding are more likely to breastfeed for more than 6 months (p < 0.0005).

Conclusion

Based on this information, we conclude that breastfeeding support networks have a positive influence in the duration of a women’s decision to breastfeed.  相似文献

This article focuses on research ethics in highly intimate research with possible impact on life and death. In order to stimulate an open-ended dialogue about research ethics, we reflect on four ethical challenges that came up during our research into older people with a wish to die. Drawing on our experiences, we discuss (1) the possibly confirming influence of our research on the death wish (moral experience of whether or not to disregard responsibility); (2) the suggested duty to intervene (moral experience of whether or not to compromise the person’s autonomy); (3) the researcher’s authority and power over the data (moral experience of threatening a person’s self-narrative) and (4) the dilemma of intimacy (moral experience of encountering the tragic). For guidance in addressing these challenges, we draw upon work on research ethics from phenomenological and care ethics scholars, as well as from those writing about relational ethics in health research. We suggest that being open about ethical uneasiness is important, because in most cases of a grey area, there are only open-ended answers needing an enquiring mind, rather than clear and fixed guidelines. Acknowledgement of ethical uneasiness and open-ended reflexivity are indispensable to constitute a morally good research practice.  相似文献

As numbers of families with same-sex parents increase in the United States, children are more likely to encounter diverse family structures. Given that young children can demonstrate in-group bias, prejudicial attitudes, and social exclusion, it is important to understand how children perceive their peers in diverse families. To our knowledge, no studies have assessed elementary-school-age children's attitudes about same-sex parent families. Here, 131 elementary school students (Mage = 7.79 years; 61 girls) viewed images of same-sex (female and male) and other-sex couples with a child and then were asked about their perceptions of these families, particularly the children. Results indicated participants' preferences toward children with other-sex versus same-sex parents. Developmental and practical implications about children's attitudes toward sexual minority parent families are discussed.  相似文献

Emergency material allocation is an important part of postdisaster emergency logistics that is significant for improving rescue effectiveness and reducing disaster losses. However, the traditional single‐period allocation model often causes local surpluses or shortages and high cost, and prevents the system from achieving an equitable or optimal multiperiod allocation. To achieve equitable allocation of emergency materials in the case of serious shortages relative to the demand by victims, this article introduces a multiperiod model for allocation of emergency materials to multiple affected locations (using an exponential utility function to reflect the disutility loss due to material shortfalls), and illustrates the relationship between equity of allocations and the cost of emergency response. Finally, numerical examples are presented to demonstrate both the feasibility and the usefulness of the proposed model for achieving multiperiod equitable allocation of emergency material among multiple disaster locations. The results indicate that the introduction of a nonlinear utility function to reflect the disutility of large shortfalls can make the material allocation fairer, and minimize large losses due to shortfalls. We found that achieving equity has a significant but not unreasonable impact on emergency costs. We also illustrate that using differing utility functions for different types of materials adds an important dimension of flexibility.  相似文献
