The worldwide increase in societal challenges is putting pressure on humanitarian organizations to develop sophisticated approaches to leverage social innovations in the humanitarian sector. Since humanitarian problems are complex problems, with the relevant knowledge being hidden, organizational search theory advocates the application of bottom‐up and theory‐guided search processes to identify the social innovations that solve these. Unfortunately, there has been no theoretical attention to understanding which approaches apply in this context. Further, established theory‐guided bottom‐up search processes, such as the lead user method, are unsuitable to the humanitarian sector, and we lack practice examples of adequate search processes. To start addressing this gap in theory and practice, procedural action research was done with the International Federation of Red Cross and Red Crescent Societies to develop a theory‐guided bottom‐up innovation search process for the real‐life humanitarian problem of recurring floods in Indonesia. It revealed that an innovation search process for this context must differ significantly concerning its objectives and the steps to be taken from the lead user method, which was used as a starting point. Further, a comparison of the technical quality and the social impacts of the identified social innovations with social innovations identified through a non‐theory‐guided bottom‐up search process (i.e., an innovation contest) suggests the superiority of this theory‐guided search process. With this conclusion and the insights derived throughout the development of the search process, this study makes important contributions to theory development in the social and open innovation literatures and delivers important recommendations for social innovation practice in the humanitarian sector.  相似文献

Adoption literature is largely subject to a pro‐change bias; researchers mainly assume that consumers are open to change and thus interested in evaluating new products. However, consumers often reject innovations without considering their potential, such that the adoption process ends before it really has begun. The present study instead argues that innovation resistance, prior to product evaluation, is a regular consumer response that must be recognized and managed to facilitate new product adoption. The authors suggest differentiating passive from active innovation resistance. While passive innovation resistance results from a consumer's generic predisposition to resist innovations prior to new product evaluation, active innovation resistance is an attitudinal outcome that follows an unfavorable new product evaluation. This study also extends extant innovation decision models by describing how passive and active innovation resistance emerge and how they affect decision‐making in later stages of the process.  相似文献

We investigate the interdependence of debt financing and R&D activities of young firms. Applying a bivariate Tobit model, we find that there is a positive interdependent relationship between the share of loan financing and R&D intensity. A higher share of loan financing allows for more R&D in young firms and, at the same time, a higher R&D intensity allows for a higher loan share. This result is mainly driven by start‐ups exhibiting high values of R&D intensity or leverage. Another remarkable result of our study is that the positive relationship between R&D and loan financing can only be detected if we consider that, first, the decisions on R&D and on loan financing are made simultaneously and, second, the decision on R&D impacts the decision on loan financing and vice versa.  相似文献

We analyze the role of personality in occupational choice and wages using data from Germany for the years 1992 to 2009. Characterizing personality by use of seven complementary measures (Big Five personality traits, locus of control, and a measure of reciprocity), the empirical findings show that personal characteristics are important determinants of occupational choice. Associated with that, identical personality traits are differently rewarded across occupations. Hence, breaking down the analysis on the level of occupational groups provides more detailed results of returns to personality. By evaluating different personality profiles, we additionally estimate the influence of personality as a whole. The estimates establish occupation-specific patterns of significant returns to particular personality profiles. These findings underline the importance to consider the occupational distribution when analyzing returns to personality due to its heterogeneous valuation.  相似文献

The present paper reviews the literature on the risks and benefits of aquaculture. By bringing together sources from both natural sciences and social sciences, we provide a synthesis of perspectives on the relatively novel activity of modern aquaculture. This review consists of three parts: first, a background to aquaculture; second, an overview of the scientific risks and benefits; and third, an introduction to the related public perception issues. We establish five main risk‐related areas: human health, environment, organizational, fish welfare, and social issues and utilize these to highlight potential divergences in expert and lay perceptions. Drawing on findings from the risk perception literature, particularly those related to previous food‐related controversies, it is argued that aquaculture incorporates a range of issues, which have already been shown to be a catalyst for public concern. As such, we conclude that, in addition to natural science studies, aquaculture requires a social science approach in order to be able to anticipate and address future controversies in a timely and efficient manner. However, to date, only few articles address aquaculture from a social science perspective, and the present paper is offered as a step in this direction.  相似文献
