To understand why some international institutions have stronger dispute settlement mechanisms (DSMs) than others, we investigate the dispute settlement provisions of nearly 600 preferential trade agreements (PTAs), which possess several desirable case-selection features and are evoked more than is realized. We broaden the study of dispute settlement design beyond “legalization” and instead reorient theorizing around a multi-faceted conceptualization of the strength of DSMs. We posit that strong DSMs are first and foremost a rational response to features of agreements that require stronger dispute settlement, such as depth and large memberships. Multivariate empirical tests using a new data set on PTA design confirm these expectations and reveal that depth – the amount of policy change specified in an agreement – is the most powerful and consistent predictor of DSM strength, providing empirical support to a long-posited but controversial conjecture. Yet power also plays a sizeable role, since agreements among asymmetric members are more likely to have strong DSMs due to their mutual appeal, as are those involving the United States. Important regional differences also emerge, as PTAs across the Americas are designed with strong dispute settlement, as are Asian PTAs, which contradicts the conventional wisdom about Asian values and legalization. Our findings demonstrate that rationalism explains much of international institutional design, yet it can be enhanced by also incorporating power-based and regional explanations.  相似文献

School can be regarded as an important factor in the development of children’s values and attitudes. Given this great importance of justice experiences for students’ development, this study aimed at examining the influence of perceived injustice in school on students’ emotions, well-being, and behavior with an experimental longitudinal design. In total, 196 students participated in this study and came to the university with their classes to receive extra teaching once a week for six consecutive weeks. To manipulate justice perceptions, a scenario of arbitrary privilege was chosen to lead students of the experimental group to experience injustice from a beneficiary perspective. We found that students in the experimental group reported higher well-being and a higher appreciation of the opportunity to learn than the control group did. Additionally, they showed an increase in justice-related negative emotions over time; that is, they expressed more of a bad conscience and stronger feelings of anger the more they became aware of their privilege. This study shows that even subtle experiences of injustice in school can have an impact on students’ outcomes. These results are discussed with regard to practical implications.  相似文献

The difference in official crime statistics between women and men is a constant fact in criminology, but has yet to be explained in a satisfactory way. There are few studies addressing the issue of why this gender gap is larger in registered crime than it is in self-report studies. The study at hand comprises a survey among Greek and German students to examine whether this gap could be attributed to a gender-specific reporting of crime. Participants’ self-reported experiences of victimisation and their rating of the seriousness of offences depicted in case vignettes were used to gain insight into varying tendencies to report a crime depending on the offender’s gender. The act of reporting a crime did not vary gender-specifically.  相似文献

Maximum security correctional officers play a crucial role in the establishment of order within their respective institutions of employment, yet they are also exposed to numerous occupational dangers that can threaten their general welfare. When they perceive high levels of injurious risk from workplace hazards, this cannot only jeopardize their job performance but lead to a poorly managed prison institution. Currently though, few studies have explored correctional officer perceptions of workplace dangers and risks, and even fewer have explored the factors that influence officer perceived risk of injury. Questionnaire data from a statewide population of maximum security correctional officers (N?=?649) were gathered in order to examine officer perceived risk of injury from workplace dangers, and the antecedents to this judgment. Results illustrated how officers perceived a high degree of injurious risk from their work, and that their risk perceptions were largely a product of psychological features of dangers. Theoretical and policy implications are discussed.  相似文献

Two cross-sectional questionnaire studies were conducted to replicate and extend previous research on the existential guilt reaction. In Study I, gender was considered as a privilege. Male student participants (N = 141) were confronted with the low proportion of women in high-ranking positions and asked to appraise this situation. Self-reported behavior, behavioral intentions, and appeal to authorities aimed at advancing equal opportunities for both genders served as criterion variables. Path analyses were performed to explore the correlation structure among the variables. Self-reported behavior depended most strongly on behavioral intentions and on belief in control. Behavioral intentions depended most strongly on existential guilt. This effect accords to previous existential guilt research. Ethnicity and education were considered as privileges in Study II. Privileged Paraguayan students (N = 80) were confronted with the disadvantageous living conditions of Indians and Campesinos. They were asked to appraise the situation. Behavioral intentions and appeal to authorities directed at improving the living conditions of Indians and Campesinos served as criteria. As in Study I, existential guilt was the strongest predictor of behavioral intentions. Study II revealed the role of values in the process of existential guilt and prosocial behavior. This is a new research finding. Indirect effects of the two values of universalism and benevolence on behavioral intentions were obtained. The effect of universalism was mediated by existential guilt and moral outrage, the effect of benevolence was mediated by injustice and existential guilt. Tradition had a negative indirect effect on behavioral intentions. This effect was mediated by justification of deprivation and probably means that adherence to tradition eases the justification of traditionally existing social inequalities in a society.  相似文献

Public‐Private Partnerships (PPP) procurement is routinely portrayed as offering greater scope for harnessing competitive market forces to secure Value for Money (VfM) than traditional procurement approaches ( OECD 2008 ). The aim of this article is (a) to demonstrate the importance of periodically taking a more systematic and strategic view when assessing VfM in PPP procurement ( OGC 2003 ), and (b) to develop an analytical framework for such an analysis. Road infrastructure procurement in South East Queensland is used as a case study to test the usefulness of the proposed framework, and to show how a narrow focus on individual contracts increases the risk of overlooking overdependence on one supplier ( OGC 2003 ). Discussion focuses on the need to combine detailed analysis of individual contracts with longitudinal analyses of market competitiveness when assessing best VfM.  相似文献

This study examines the role of public–private partnerships (PPPs) in promoting pro‐poor productivity‐enhancing technological innovation in the international agricultural research system. The study examines the extent to which PPPs are being used to overcome market and institutional failures that otherwise inhibit the development and dissemination of technologies targeted specifically to small‐scale, resource‐poor farmers in developing countries. Drawing on a survey of 75 PPP projects in the international system, findings suggest that while PPPs are changing the way the system manages its research agenda, few partnerships lead to joint innovation processes with the private sector. This indicates the need for closer examination of organizational practices, cultures, and incentives in the international agricultural research system.

The private nonprofit hospital is the dominant organizational form in the U.S. hospital industry. Various reasons have been advanced for its high market share. As hospitals undergo massive changes due in large part to changes in payment practices, there is widespread concern that nonprofit hospitals may become less committed to noncommercial activities. This may even be more likely when such hospitals convert to for-profit status. The empirical evidence indicates that, on average, hospitals of nonprofit and for-profit ownership are similar in the provision of uncompensated care, the quality of care, and the adoption of technology. Conversion of a nonprofit to for-profit status does not adversely affect the provision of uncompensated care on average. However, for-profits are more likely to be located in areas where consumers have the ability to pay for care. As hospital markets become more competitive and the opportunity for cross-subsidizing more unprofitable, collective-good activities will become increasingly difficult. Support for such activities, if they are to exist, will have to come from explicit public subsidies.  相似文献
