In multistakeholder sustainability initiatives, nongovernmental organizations (NGOs) need not only to negotiate with actors from other sectors, but also with other NGOs. Taking a framing perspective, this study examines how NGOs engage in framing contests because of their collaborative attitude toward the private sector. Through an analysis of Oxfam's participation in the Shrimp Aquaculture Dialogues, the paper examines the interplay between NGOs that propose and oppose certification as a viable strategy for ensuring sustainability in the farmed shrimp sector. The results show that controversies among NGO groups related prognostic framing (i.e., regarding the proposed solution to a problem) are characterized by specific ontological and normative attributes. The paper offers NGOs strategies for dealing with such controversies and shows that, depending on the nature of the controversy, engaging in framing contests might enlarge or constrain the roles that an NGO is able to play in a multistakeholder setting, particularly, when it comes to preserving its independence while securing interdependence with others.  相似文献

Emerging markets have created significant opportunities for European small- and medium-sized enterprises (SMEs). Highly dissimilar market contexts compared to traditional markets and missing resources present substantial barriers to successfully serve those markets. Collaborative partnerships with local SMEs can help to overcome the barriers. Knowledge on how SMEs can develop lasting collaborative relationships in highly dissimilar contexts is scarce. This research investigates which factors influence the stability of more informal collaborative partnerships of Central European SMEs with SMEs located in China. A qualitative analysis of four cases confirms the importance of complementarity of partner resources, working well together based on mutual trust and commitment, shared sensemaking, and the balanced consideration of partner interests. Mutual learning and adaptation in iterative steps to enhance shared sensemaking and seeing differences in interpretation and behavior arising from contextual dissimilarity as opportunities instead of threats turn out to be SME-specific factors essential for building stable informal collaborative relations.  相似文献

Forecasts of life expectancy (LE) have fuelled debates about the sustainability and dependability of pension and healthcare systems. Of relevance to these debates are inequalities in LE by education. In this paper, we present a method of forecasting LE for different educational groups within a population. As a basic framework we use the Li–Lee model that was developed to forecast mortality coherently for different groups. We adapted this model to distinguish between overall, sex-specific, and education-specific trends in mortality, and extrapolated these time trends in a flexible manner. We illustrate our method for the population aged 65 and over in the Netherlands, using several data sources and spanning different periods. The results suggest that LE is likely to increase for all educational groups, but that differences in LE between educational groups will widen. Sensitivity analyses illustrate the advantages of our proposed method.  相似文献

Social media provide new opportunities for politicians, such as personalized communication directed at specific communities of interest. Yet despite potential benefits, empirical analyses show that politicians tend to shy away from an active engagement of online audiences. This study explores the effect of politicians’ online boundary management on their use of social media. Ties maintained through social media profiles can be embedded in diverse social contexts (‘context collapse’). Professional communicators, especially, are faced with the challenge of managing boundaries between professional and private online self-presentations. Based on a survey of 106 German members of parliament, we distinguish four types of boundary management strategies. We analyze the effects of these strategies on politicians’ social media use practices – and find that considering boundary management strategies allows for a better understanding of politicians’ online engagement (or lack thereof).  相似文献

To develop and evaluate the Loneliness Literacy Scale for the assessment of short-term outcomes of a loneliness prevention programme among Dutch elderly persons. Scale development was based on evidence from literature and experiences from local stakeholders and representatives of the target group. The scale was pre-tested among 303 elderly persons aged 65 years and over. Principal component analysis and internal consistency analysis were used to affirm the scale structure, reduce the number of items and assess the reliability of the constructs. Linear regression analysis was conducted to evaluate the association between the literacy constructs and loneliness. The four constructs “motivation”, “self-efficacy”, “perceived social support” and “subjective norm” derived from principal component analysis captured 56 % of the original variance. Cronbach’s coefficient α was above 0.7 for each construct. The constructs “self-efficacy” and “perceived social support” were positively and “subjective norm” was negatively associated with loneliness. To our knowledge this is the first study developing a short-term indicator for loneliness prevention. The indicator contributes to the need of evaluating public health interventions more close to the intervention activities.  相似文献

In this paper we compare Bartlett-corrected, bootstrap, and fast double bootstrap tests on maximum likelihood estimates of cointegration parameters. The key result is that both the bootstrap and the Bartlett-corrected tests must be based on the unrestricted estimates of the cointegrating vectors: procedures based on the restricted estimates have almost no power. The small sample size bias of the asymptotic test appears so severe as to advise strongly against its use with the sample sizes commonly available; the fast double bootstrap test minimizes size bias, while the Bartlett-corrected test is somehow more powerful.  相似文献

We analyze a general search model with on‐the‐job search (OJS) and sorting of heterogeneous workers into heterogeneous jobs. For given values of nonmarket time, the relative efficiency of OJS, and the amount of search frictions, we derive a simple relationship between the unemployment rate, mismatch, and wage dispersion. We estimate the latter two from standard micro data. Our methodology accounts for measurement error, which is crucial to distinguish true from spurious mismatch and wage dispersion. We find that without frictions, output would be about 9.5% higher if firms can commit to pay wages as a function of match quality and 15.5% higher if they cannot. Noncommitment leads to a business‐stealing externality which causes a 5.5% drop in output.  相似文献

The consensus value: a new solution concept for cooperative games   总被引:1,自引:0,他引:1  
To generalize the standard solution for 2-person TU games into n-person cases, this paper introduces a recursive two-sided negotiation process to establish cooperation between all players. This leads to a new solution concept for cooperative games: the consensus value. An explicit comparison with the Shapley value is provided, also at the axiomatic level. Moreover, a class of possible generalizations of the consensus value is introduced and axiomatized with the Shapley value at one end and the equal surplus solution at the other. Finally, we discuss a non-cooperative mechanism which implements the consensus value.  相似文献
