In this paper, we examine how organizations’ impression management (IM) evolves in response to rising stakeholder pressures regarding organizations’ corporate responsibility initiatives. We conducted a comparative case study analysis over a period of 13 years (1997–2009) for two organizations—Exxon and BP—that took extreme (but different) initial stances on climate change. We found that as stakeholder pressures rose, their IM tactics unfolded in four phases: (i) advocating the initial stance, (ii) sensegiving to clarify the initial stance, (iii) image repairing, and (iv) adjusting the stance. Taken together, our analysis of IM over these four phases provides three key insights about the evolution of IM in the face of rising pressures. First, when faced with stakeholder pressures, it seems that organizations do not immediately resort to conforming but tend to give in gradually when pressures increase and start to come from relatively powerful stakeholders. Second, evolution of IM seems to be characterized by path dependence, i.e., even as organizations’ positions evolve, they continue to show their conviction in their initial positions and try to convey that their subsequent positions flow logically from the previous ones. Finally, IM involves navigation between symbolism and substance, and companies tend to strive toward harmonizing their symbolic and substantive actions as stakeholder pressure increases.  相似文献

Given the importance of cowpea [Vignaunguiculata(L)Walp] in fighting malnutrition and poverty, a socio‐economic assessment of cowpea diversity found on the Ghanaian market was conducted. The objective was to investigate emerging consumer preference for cowpea and make recommendations for the development of tailor‐made varieties. Forty‐seven cowpea accessions were collected from traders interviewed for morphological characterization to ascertain the degree of diversity. Data was subjected to Hierarchical Cluster Analysis using Genstat Discovery Edition 3 software and variations among the cowpea varieties based on the selected seed traits established. Cowpea varieties found on the markets were broadly categorized into foreign and local varieties and usually named after their sources. Foreign Cowpea varieties were very popular on the markets surveyed as reflected in the per cent distribution of respondents by cowpea varieties sold; Niger (52%), Burkina Faso (50%), Togo (46%), Lagos (36%) and Ghana (18–21%). At the trader level, the order of preference for cowpea characteristics was cleanliness (stone free and no dirt), colour (white seed colour), easy to cook, taste, size, less weevil damage, dryness and place of origin ranked in decreasing order of importance. At the consumer level, cleanliness that was also tied to the extent of weevil damage was ranked most important. This was followed by seed colour (preferable white), short cooking time, size and taste. From the sociological perspective, concerns are raised on the impact of past cowpea breeding activities giving the level of competitiveness and market performance of locally improved varieties observed. Recommendation is made for traders and consumers to be considered as relevant actors in all the stages of crop improvement and breeding activities. This is crucial for enhanced small‐holder farmer market access and strengthened food networks in rural economies.  相似文献

ABSTRACT

The projected global expansion in consumption of meat and other livestock products potentially offers sub-Saharan African small-holder farmers opportunities to escape from the poverty trap. A necessary condition for exploiting this potential is the establishment of marketing systems that provide farmers with reasonable incentives to participate in the market. In this study, the functioning of livestock markets in rural Uganda is analyzed based on a survey of 401 livestock keepers, complimented with focus group discussions with livestock traders and policy planners. The first part is dedicated to the empirical analysis of key organizational and institutional arrangements. Constraints along the marketing chain as well as potential institutional solutions are illuminated. The second part is dedicated to propositions of new areas where more work and new results are needed to improve the functioning of the livestock marketing chain. Empirical findings indicated the following institutional constraints: a poor market information system, lack of grades and standards, lack of trade finance, poor contract enforcement and dispute settlement, disorganized actors, high transaction risks, and poorly developed marketing infrastructure. The study recommends a structured approach to livestock marketing, market infrastructure development, and emphasis on arbitration systems as specific ways of improving the efficiency of livestock marketing in Uganda and other developing countries.  相似文献

This paper explores the willingness of Belgian farmers to participate in two voluntary agri‐environmental policies. Farmers' contingent behaviour is analysed on the basis of survey data. Derivations based on a conceptual micro‐economic model indicate that decision subject and decision maker characteristics are important for farmers' participation. The model is empirically tested through the specification and estimation of a probit model. Consistency is found between the theoretical framework and the empirical results indicating that both the expected effect on farm production and the farmers' environmental attitude, which is more positive among younger and better educated farmers, are significant determinants of the acceptance rate of agri‐environmental policies. Other variables which influence participation decisions are farm size and previous experience of farmers themselves or of neighbouring farmers with agri‐environmental measures.  相似文献

In this article we describe a system of stochastic differential equations to model the age‐specific prevalence of rare chronic diseases from incidence and mortality rates. As an application, the age profile of the prevalence of systemic lupus erythematosus in England and Wales in1995 is calculated. The results are in good agreement with the observed epidemiological measures.  相似文献

This article extends the literature on CEO succession and financial performance by addressing corporate owners' mixed motives and desires to protect their interest in being in business. We draw on a Socio‐Emotional Wealth (SEW) perspective to investigate how the choice of one of three succession mechanisms – relay succession, ‘horse races’ among internal CEO candidates, and hiring from outside – may effectively balance trade‐offs between corporate owners' non‐financial SEW motives and the firm's financial performance. We find that implementing one of these succession mechanisms reduces the negative impact that typically characterizes CEO transitions in family firms. We also show that family presence on the board of directors offsets the benefits of having selected these balancing succession mechanisms, in either placing too much emphasis on SEW, or creating negative dynamics that make the chosen succession mechanisms less effective.  相似文献
