The idea of geoengineering, or the intentional modification of the Earth's atmosphere to reverse the global warming trend, has entered a working theory stage, finding expression in a variety of proposed projects, such as launching reflective materials into the Earth's atmosphere, positioning sunshades over the planet's surface, depositing iron filings into the oceans to encourage phytoplankton blooms, and planting more trees, to name only a few. However, geoengineering might not be as promising a solution to the problem of global warming as its advocates claim. Many scientists, policy makers, and ethicists still dismiss the option as infeasible and too risky given the immense scale at which most geoengineering projects must be instituted and the catastrophic consequences that could, in all likelihood, result. The thesis of this article is that geoengineering should not be so easily dismissed in policy debates concerning how to mitigate the anthropogenic emissions of global greenhouse gases. My plan is to investigate the desirability of the geoengineering option for addressing global climate change in terms of its capacity to overcome collective action issues, to accommodate ethical norms, and to provide an artful, or creative, response to the problem. In the first section, a general picture of the global warming problem and the particulars of some proposed geoengineering projects are laid out. The second section frames the issue as a collective action problem that demands an innovative approach to coordinating individual and group action. In the third section, I reveal six ethical quandaries that emerge in global climate change debates and how they complicate any attempts to ameliorate or resolve the problem. The penultimate section shows how the ideas and activism of two twentieth‐century titans in philosophy and ecology—John Dewey and Aldo Leopold, respectively—might be combined to address the problem of global warming through artful inquiry and the adoption of an Earth ethic. Finally, I conclude by arguing that a fundamental shift in perspective must occur if we are to take intentional climate change seriously as a possible, even if a second‐best, tool in the environmentalist's tool kit. 相似文献

Motor vehicle collisions (MVCs) are the second leading cause of traumatic brain injury (TBI), accounting for between 17 and 28 % of all TBIs. Although about 86 % of those who are involved in MVCs sustain no injuries, the remaining 14 % commonly experiences temporary or permanent cognitive, physical, and emotional problems; decreased functioning; and adverse lifestyle changes, which often result in litigation or pursuit of disability benefits. Although by far the most common severity of brain trauma resulting from MVCs falls at the mild end of the spectrum, many patients sustain moderate and severe brain injuries. Because of differing neuropathology, clinical presentations, recovery courses, and treatment and care needs, the neuropsychological conceptualization of, and services provided to, those who have sustained mild traumatic brain injuries typically differ from the conceptualization and services needed for those who sustained moderate–severe TBIs. Physical pain, emotional distress, effects of medications, and various motivations to seek services often contribute to the complexity of issues experienced by patients and confronted by clinicians. The purpose of this article is to review the assessment and treatment of cognitive, emotional, and behavioral problems experienced by persons who have been involved in MVCs, with a primary focus on outpatient settings and TBIs that fall at the mild end of the severity spectrum. 相似文献

Measuring the Geographical Displacement and Diffusion of Benefit Effects of Crime Prevention Activity 总被引:1,自引:0,他引:1
The displacement of crime is an important criminological phenomenon. However, while there has been theoretical discussion of this issue in the research literature, there has been little in the way of either standardized empirical work that investigates the incidence of displacement or in the development of techniques that can be used to measure it. In the current paper we discuss a new technique, the weighted displacement quotient (WDQ), that was developed to measure the geographical displacement of crime. A critical feature of the rationale is that displacement can only be attributed to crime prevention activity if crime is reduced in the target area considered. Thus, the WDQ not only measures what occurs in a buffer (displacement) zone but also relates changes in this area to those in the target area. Part of the appeal of the measure is that it can be used either with aggregate or disaggregate crime data and for any geographical boundary selected, provided the appropriate data are available. In addition to detecting displacement, when detailed data are available, the technique can also be used to identify where the effect was most prominent. The WDQ can equally be used to measure the diffusion of benefit of any crime prevention activity. A series of examples are presented for illustration purposes. 相似文献

Previous research into pollen content of tobacco resulted in a debate. We address this debate and determine that pollen analysis may be able to assist with identifying geographical origin of tobacco. However, the value of any results should be assessed on a case‐by‐case regional basis until sufficient database information is available for an objective interpretation to be undertaken on a global basis. As a first step toward developing comparative data for South America, we analyzed a tobacco sample from Brazil in an effort to identify signature taxa from the state of Minas Gerais. We also assessed the role of honey additives to tobacco to assess this issue. Comparing the data to previously published data, we conclude that pollen signatures can distinguish broad geographic areas. We conclude that this forensic interpretation framework needs to be developed in context of the National Academy of Sciences recommendations for tightening methods in forensic science. 相似文献

Previous research indicates that supporting a winning party in an election boosts satisfaction with democracy, but does not fully or adequately test the mechanisms behind this relationship. Using original survey data, we make a contribution on three fronts. First, we inquire what winning (or losing) an election really means in terms of the performance of one’s preferred party. Second, we employ panel data, which helps to determine whether an election outcome truly impacts satisfaction levels. Third, we examine the breadth of electoral victory, testing whether the satisfaction boost from a regional victory extends to the national and supranational levels. Findings indicate that the inclusion of one’s selected party in government is the most important factor for satisfaction with democracy, which attests to the importance of policy considerations in engendering satisfaction. In addition, winning a regional election strengthens satisfaction beyond the regional level, which indicates that the mere experience of being a “winner” also works to increase satisfaction. 相似文献
