This study evaluates whether the education, environmental expertise, and nationality of firms' chief executive officers (CEOs) are associated with greater participation and environmental performance in a voluntary environmental program implemented in a developing nation. Specifically, we collected data from the Certification for Sustainable Tourism (CST) program, a voluntary initiative aimed at promoting beyond-compliance environmental performance by hotels operating in Costa Rica. Our findings suggest that CEOs' level of formal education and environmental expertise appear to be significantly associated with higher corporate participation in voluntary programs and also with higher beyond-compliance environmental performance ratings. Contrary to conventional expectations, CEOs from industrialized countries (as opposed to developing countries) do not appear to show a statistically significant association with participation in the CST program and with higher beyond-compliance environmental performance. 相似文献
We analyze the way in which individual academics and research groups organize their third mission activities before and after the institutionalization of third mission strategies by the university governing body. Drawing on the literature, we put forward an interpretative framework that links central entrepreneurial or engaged strategies with the way academics organize their third mission activities. Then, we propose an application of this frame to the case of the University of Florence (Italy), before and after its transition to more structured entrepreneurial and engaged models. We use a mix of quantitative and qualitative analysis. A cluster analysis allows identifying different types of academics involved in the third mission based on the way they organize their activities. Furthermore, a set of interviews to academics complements the comparison and the interpretation of the clusters obtained. The following paths of change emerge: (1) increased proportion of academics involved in third mission activities; (2) bottom-level initiatives that are aligned with central strategies; and (3) increased heterogeneity of bottom-level organization forms, with a relative loss of importance of the group dimension with respect to the individual academics and an increased specialization of research groups.
Psychological pain has been reported to be major contributing factor for completed suicide, and classical suicidology based its wisdom on this construct. In this paper we report the case of a patient whose family experienced a high number of suicides apparently due to an escalation of psychological pain in the family members after the successive suicides. We also briefly discuss the problem of helping survivors after the suicide of loved one. 相似文献
During the last decades, the activities of pirates have increased exponentially in Eastern Africa, with their attacks becoming considerably more violent. In addition to the intrastate and interstate conflicts, the lack of state capacity and the presence of terrorist groups, maritime piracy represents a serious and sustained threat to economic security. Indeed, from an economic point of view, pirates affect international trade through an increasing insecurity related to the prompt delivery of the goods transported. The aim of this work is to explore the main works on maritime piracy analyzed in quantitative economics. 相似文献
This article analyzes the reasons why individuals oppose the siting of nuclear waste repositories close to their hometowns. In a simple model based on survey data, we show that the willingness to accept such facilities largely depends on economic criteria, namely expected economic impacts and risk estimates. However, the predictive power of such a model is improved by focusing not only on the consequences—as economic models typically do—but also on the procedural aspects. We show that acceptable siting rules contribute positively to the willingness of local residents to host a noxious facility. Acceptable rules, it is found, are essentially fair rules. 相似文献
Many studies in the literature have highlighted the utility of virtual 3D databanks as a substitute for real skeletal collections and the important application of radiological records in personal identification. However, none have investigated the accuracy of virtual material compared to skeletal remains in nonmetric variant analysis using 3D models. The present study investigates the accuracy of 20 computed tomography (CT) 3D reconstruction models compared to the real crania, focusing on the quality of the reproduction of the real crania and the possibility to detect 29 dental/cranial morphological variations in 3D images. An interobserver analysis was performed to evaluate trait identification, number, position, and shape. Results demonstrate a false bone loss in 3D models in some cranial regions, specifically the maxillary and occipital bones in 85% and 20% of the samples. Additional analyses revealed several difficulties in the detection of cranial nonmetric traits in 3D models, resulting in incorrect identification in circa 70% of the traits. In particular, pitfalls included the detection of erroneous position, error in presence/absence rates, in number, and in shape. The lowest percentages of correct evaluations were found in traits localized in the lateral side of the cranium and for the infraorbital suture, mastoid foramen, and crenulation. The present study highlights important pitfalls in CT scan when compared with the real crania for nonmetric analysis. This may have crucial consequences in cases where 3D databanks are used as a source of reference population data for nonmetric traits and pathologies and during bone-CT comparisons for identification purposes. 相似文献
In the present studies, we aimed to show that the perceived procedural fairness of societal actors’ multicultural decisions promotes ethnic minority members’ societal identification. These enhanced identification levels, in turn, contribute to better psychological health and well-being. Firstly, a vignette study in a sample of African Americans explored the effect of procedural fairness climate on identification. The second and third studies used self-report questionnaires. Study 2 consisted of a sample of sojourners in a university context, Study 3 analyzed online data through an African American sample. The studies provided evidence for the effect of procedural fairness climate on increased societal identification, which in turn mediates the fairness effect on increased well-being and psychological health. Societal actors can use procedural fairness to increase well-being when making decisions that involve ethnic minorities.
