Endowed with the state monopoly on the legitimate use of even potentially lethal force, it is intolerable for police officers to act outside the governing legal and ethical framework. At the same time, officers are expected to exert self-control and refrain from excessive use of force when they deal with provocative and perilous situations. This study sought to investigate corresponding self-control and self-control failures through the role of ego depletion in the decision to use force by police officers. Two experiments were conducted using officers from a German State Police force, requiring the participants to use force against a provocative role player. Experiment 1 found that the ego depletion measure failed and there were no differences between the groups. Using a different ego depletion method, experiment 2 found that ego-depleted participants aggressed earlier than controls. These results indicate that circumstances that produce ego depletion could lead to the inappropriate use of force through reducing self-control. This has major implications for the police use of force and how we understand police officers’ decision-making in response to provocation. 相似文献

This article looks at the shifting intricacies of British assessments of the Soviet IRBM threat to the United Kingdom during the 1950s. Based on JIC, Cabinet and Air Ministry records of the period, as well as political memoirs, it looks at the assessments in parallel with the development of the British Blue Streak nuclear ballistic missile programme. This land‐based weapon was eventually cancelled in April 1960 on strategic not cost grounds, too early in this author's opinion. 相似文献

The introduction of the Global Terrorism Database (GTD) nearly a decade ago sparked a revolution in terrorism studies. However, one major flaw in the database continues to plague GTD users. Data lost prior to digitalization, along with unsuccessful data recollection efforts, have left GTD without data on events that took place during the year 1993. The missing data prevents researchers from using the entirety of GTD's annual range (1970–2014) to conduct reliable time-series analyses. Additionally, it has likely contributed to the formation of theories and claims on faulty empirical ground. To remedy the problem, we have collected data on 4,206 unique terror-attack incidents, with the aim of documenting the universe of 1993 terrorism events. This article showcases our 1993 dataset and illustrates the importance of terrorism events in 1993 for the development of conflicts in Israel, Afghanistan, Colombia, and India. 相似文献

The fossil fuel divestment movement has been described as the fastest‐growing disinvestment movement in history, and in recent years it has continued to expand. Despite its growth, however, the movement has made little use of legal action, instead utilizing tactics of public pressure and persuasion, and the future role of litigation in the movement is unclear. To consider litigation's potential role in the movement and the challenges it may face, I examine the first and only case of litigation in the fossil fuel divestment movement thus far: Harvard Climate Justice Coalition et al. v President and Fellows of Harvard College et al. (2015), in which seven Harvard students (including the author) filed suit to compel the university to divest its endowment from fossil fuel companies. I examine motivations for filing the suit in the context of the broader fossil fuel divestment movement, the case's history, and the challenges faced by the suit, including arguments surrounding causation, particularization, representation of future generations, limiting principles, and framing. I then discuss potential opportunities for fossil fuel divestment litigation in the future. As the field of climate change law develops further, litigation over fossil fuel investments could grow in frequency and importance. 相似文献

We examine the academe–industry wage gap. Once self-selection and different personal characteristics of academic and industrial scientists have been taken into account the wage gap narrows from 28 to 13 %. The counterfactual wage faced by an academic scientist increases with time spent on development and decreases with time spent on research. This finding challenges the idea of a solely negative relationship between science and wages. We further find that preferences for science augment the relationship between research orientation and wages. Overall, the results have implications for policy makers that aim to increase development oriented research activities at universities, individual scientists thinking about whether to pursue a career in industry or academe, and managers trying to hire academic scientists. 相似文献

This article examines the relationship between fiscal year 1990 Fish and Wildlife Service spending on endangered species recovery and the priority ranking assigned by the Fish and Wildlife Service to particular species. The focus of the analysis is on the extent to which resources were allocated to species assigned higher priority rankings. The major conclusions are: species' recovery priority rank is not related to funding decisions by the Fish and Wildlife Service; some of the individual factors that make up the overall priority ranking—recovery potential and conflict with development—are correlated to funding decisions; and the likelihood of receiving some Fish and Wildlife Service recovery funding was greater for mammals, birds, and fish. 相似文献
