The subject matter of the analysis in this paper is jus in bello and the very possibility of its existence. On the face of it, the concept that in the event of the outbreak of hostilities, the use of force against one's opponent should be somehow regulated and limited, which is stranger, and its origin is more difficult to explain, than the concept that human societies should live together in peace or that wars should only be begun on some ethical or legally acceptable grounds. It is likely that limits on the use of force, or at least pressures to keep it within a ritualized framework, are property of human beings that enabled our ancestors to live together as social animals. Something similar would have been applied for groups of such beings. Even though the tendency to regulate the use of force in war has existed in the earliest times, this is not a simple task and sets against this effort there are a number of factors that encourage the freest use of violent methods and weapons: The war is a serious business and the desire to win at all costs is very strong, the logic of war leads the combatants to employ all the forces that can be freed from elsewhere and make use of all available advantages and means, a combat is an emotional mater not only rational, etc. Against these forces, the factors that work in favor of the legal regulation of the use of force are: The existence of at least a basic common identity, a situation in which war does not have the characteristics of total war, ear of reprisals by the enemy, the principle of proportion of force used to the objectives, the existence of an approximately comparable moral code and warrior code of honor on both sides, and the need to legitimize war. The extent to which a given war will abide by legal regulation of the use of force depends on the result of the balance of the opposing factors listed above.  相似文献

This study examines prostitution, homelessness, delinquency and crime, and school problems as potential mediators of the relationship between childhood abuse and neglect (CAN) and illicit drug use in middle adulthood. Children with documented cases of physical and sexual abuse and neglect (ages 0–11) during 1967–1971 were matched with non-maltreated children and followed into middle adulthood (approximate age 39). Mediators were assessed in young adulthood (approximate age 29) through in-person interviews between 1989 and 1995 and official arrest records through 1994 (N = 1,196). Drug use was assessed via self-reports of past year use of marijuana, psychedelics, cocaine, and/or heroin during 2000–2002 (N = 896). Latent variable structural equation modeling (SEM) was used to test: (1) a four-factor model with separate pathways from CAN to illicit drug use through each of the mediating risk factors and (2) a second-order model with a single mediating risk factor comprised of prostitution, homelessness, delinquency and crime, and poor school performance. Analyses were performed separately for women and men, controlling for race/ethnicity and early drug use. In the four-factor model for both men and women, CAN was significantly related to each of the mediators, but no paths from the mediators to drug use were significant. For women, the second-order risk factor mediated the relationship between CAN and illicit drug use in middle adulthood. For men, neither child abuse and neglect nor the second-order risk factor predicted drug use in middle adulthood. These results suggest that for women, the path from CAN to middle adulthood drug use is part of a general “problem behavior syndrome” evident earlier in life.

Given the lack of empirical research investigating citizens’ use of open government, this study examines the antecedents of citizens’ use of open government data. Based on technology acceptance and motivation theory, this article proposes and empirically tests a research model, applying structural equation modeling to survey data collected from 210 citizens. The findings show that ease of use, usefulness, intrinsic motivation, and Internet competence significantly determine citizens’ intention to use open government data. Overall, this study contributes to the understanding of citizens’ attitudes and behavior in the context of open government and offers implications for research and practice.  相似文献

The goal of this article is to discover how leadership competencies affect the perceived effectiveness of crisis management. The study, based on a self-reported survey of executive public leaders in Turkey, found that the core leadership competencies have a positive relationship with the effectiveness of crisis management. Among task–oriented, people–oriented, and organization-oriented categories of leadership behaviors, task-oriented leadership behaviors were found with the highest level of impact on the effectiveness of crisis management. The study demonstrated the importance of the core leadership competencies in the effectiveness of crisis leadership. The hypothesis testing with the covariance structure model supported the positive impact of the core leadership competencies on the effectiveness of crisis management. This study contributes to the literature on leadership during crisis situations, and also provides proposals for public managers and practitioners to increase their effectiveness in leading their organizations during crises.  相似文献

Several U.S. states have supplemented traditional judicial review of local land-use regulation with a state affordable housing appeals system (SAHAS). Empirical evidence indicates that a SAHAS can increase the proportion of housing that is affordable to low- and moderate-income households. But some scholars have suggested that an effective SAHAS will ultimately backfire, by producing incentives to prohibit market-rate development, thereby rendering a state’s housing stock less affordable overall. We test this “backfire” hypothesis with a longitudinal comparison of single-family housing development from 1980 through 2007 in municipalities located in adjacent areas of Connecticut (which adopted a SAHAS in 1989) and New York State (which did not have a SAHAS during the study period). Contrary to the predictions of the backfire hypothesis, our fixed effects regression indicates that Connecticut's SAHAS was associated with increased single-family development relative to the New York State jurisdictions in our sample. This result suggests that a SAHAS can increase below-market rate and mixed-income development without impeding market-rate development.  相似文献
