The use of the recycling promotion technique which consists of commitment through a blockleader incentive has demonstrated that those individuals who are reluctant to increase their collaboration in response to the technique do not differ substantially from those who respond positively to the promotion, in terms of the processing information style. This similarity is clear, not only from the longitudinal perspective, which considers the evolution of these cognitive and evaluative variables from before the promotion application, but also from a transversal perspective, in other words, how the relationships between these variables are structured in both types of response model. However, the implications for management are based on the differences in the details of the two response patterns and a line of research based on the phenomenon of reluctance is justifiably proposed.  相似文献

This paper analyzes an election game where self-interested politicians can exploit the lack of information that citizens have about candidates’ preferred policies in order to pursue their own agendas. In such a setup, we analyze the incentives of newspapers to acquire costly information and that of politicians to make informative speeches, as well as how competition among the media affects such incentives. We show that the higher the number of potential readers and/or the lower the cost of investigating, the more the candidates tend to reveal their motives. We also show that the readers’ purchasing habits play a crucial role in the model. More specifically, we show that if readers always buy a newspaper, media competition favors information disclosure; whereas if they are opportunistic and just buy a newspaper in case news are uncovered, competition is not so desirable.

Due to the significant role of non‐profit organizations in the development of modern societies, these organizations must adjust their boardrooms. Since traditional theories of corporate governance appear to be limited in explaining the changing non‐profit world, we propose an extended model of governance that integrates the traditional arguments of agency theory with a cognitive dimension. Based on a sample of Spanish foundations, we present evidence on the effect of the board composition on foundations' organizational efficiency. We show that board size and independence do not have a definitive effect on the entity's efficiency. Instead, the knowledge diversity inside the boardroom and the active character of trustees have a positive influence on resource allocation. The cognitive dimension of the extended model of governance is critical to explaining how boards impact on organizational performance.  相似文献

We introduce an extension of the Esteban and Ray [Econometrica, 62:819–851 1994] measure of polarization that can be applied to density functions. As a by-product we also derive the Wolfson [Am. Econ. Rev., 84:353–358 1994] measure as a special case. This derivation has the virtue of casting both measures in the context of a (statistically) unified framework. We study the polarization of the distribution of household income for five OECD countries (LIS database): US, UK, Canada, Germany and Sweden. The present paper is essentially based on Esteban, Gradín and Ray [9], published as #218 in the working papers series of the Luxembourg Income Study. Changes have been kept to a minimum. We have provided a brief reference to the literature on polarization measurement that has appeared since then and have updated the data of our application.  相似文献

Duggan and Schwartz (Soc Choice and Welfare 17: 85–93, 2000) have proposed a generalization of the Gibbard–Satterthwaite Theorem to multivalued social choice rules. They show that only dictatorial rules are strategy-proof and satisfy citizens sovereignty and residual resoluteness. Citizens sovereignty requires that each alternative is chosen at some preference profile. Residual resoluteness compels the election to be single-valued when the preferences of the voters are “similar”. We propose an alternative proof to the Duggan and Schwartz’s Theorem. Our proof highlights the crucial role of residual resoluteness. In addition, we prove that every strategy-proof and onto social choice correspondence concentrates the social decision power in the hands of an arbitrary group of voters. Finally, we show that this result still holds in a more general framework in which voters report their preferences over sets of alternatives.  相似文献

The purpose of this study was to better understand the complex relationship between leisure and life satisfaction. Components of two distinct, but potentially integrative, theoretical frameworks (i.e., activity theory and need theory) predicting the relationship between leisure and life satisfaction were tested with a sample of residents from a Midwestern community (n = 633). Findings provided support for both theoretical perspectives, but stronger relationships were found between satisfied needs than with participated activities. In spite of these findings, the various inconsistencies within the two theoretical frameworks suggest that future research is needed.  相似文献

Multifamily therapy (MFT) is a psychotherapeutic group intervention for patients with severe mental disorders (SMDs) and their families. The present study is a multicenter, randomized, and controlled trial that analyzes the benefit of MFT during outpatient treatment. The recruited patients were randomly assigned to the experimental group (n = 26), which received 24 MFT sessions in addition to their treatment as usual (TAU), or to the control group (n = 29), which received only TAU (individual and family sessions). Six months after the inclusion in the MFT, the experimental group showed a significant decrease in number of visits to the psychiatric emergency services, number of psychiatric admissions, and the days of admission. The need for hospital care 6 months after recruitment was also lower in the experimental group compared to the control group. These results suggest that the implementation of MFT during outpatient treatment facilitates community management of people diagnosed with mental health problems.  相似文献

The current study examined associations between Black adolescents' (Mage = 15.55, SD = 1.23) racial discrimination and suicide behaviors (i.e., suicide ideation, suicide plan, and suicide attempts), and whether perceived school safety was a protective moderator. Furthermore, we tested gender differences in relations, which were not significant. Racial discrimination predicted greater suicide behaviors, and school safety informed less suicide behaviors. School safety moderated the relation between discrimination and suicide plan, such that at low school safety, discrimination predicted having a suicide plan but was not significant at high school safety. Furthermore, school safety moderated the relation between discrimination and suicide attempts. At low school safety, discrimination predicted more suicide attempts, but was not significant at high school safety.  相似文献

While diaries as a method have a long tradition in sociological research, few studies to date have demonstrated its value for studying health and illness. This article intends to illustrate the importance of this method for health research. The implications of the use of solicited diaries to conduct research within the field of health and illness are discussed. The contributions that the method can make to sociological research on health and illness are explored, namely the potential to capture the everyday of ill people and their family members. Indeed, this method offers an opportunity to access the experience of illness in a multidimensional approach which is not easy for researchers to catch using other methods. The article aims to present an overview of the significance of the use of diaries in health research and will make a novel contribution to the sociology of health and illness.  相似文献

There are several motives underlying the process of deciding to become an adoptive family. However, research exploring this issue is scarce and essentially focused on infertility as the main motivation. The present mixed-method study aims to fill in this gap by exploring, retrospectively, the motives to adopt of 126 Portuguese adoptive parents. The Parents' Interview on the Adoption Process was used to identify the motives to adopt and describe the adoption decision-making process. Seven main motives (biological issues, filling in a void/loneliness, adoption as a life project, expanding the family, philanthropy, contact with the child protection system and parenthood) were identified. These motives can be centred on the self, the child or both simultaneously and are characterized by dynamism, permeability and interconnection. Findings allowed for establishing conceptual considerations on motivations to adopt and recommendations for adoption practice.  相似文献
