Evaluating less than fully successful transformational leaders is difficult. One common method of assessing leadership is to focus on a single temporal narrative. A second approach uses a particular theory, such as transformational leadership, to frame the analysis. The latter, less common strategy is used with the example of Eric Shinseki, who served as both chief of staff of the U.S. Army and as secretary of the U.S. Department of Veterans Affairs (VA). The analytic framework used here has six major elements that are specified by 22 factors. Using those factors to evaluate Shinseki's tenure at the VA, he is found to be very poor in only 2 factors but poor in 11, adequate in 6, good in 1, and excellent in only 2. While using a list of factors does not eliminate subjectivity or the challenges of reaching a single assessment, it does clarify the elements of judgment and weighting.  相似文献

Legislators claim that how they explain their votes matters as much as or more than the roll calls themselves. However, few studies have systematically examined legislators’ explanations and citizen attitudes in response to these explanations. We theorize that legislators strategically tailor explanations to constituents in order to compensate for policy choices that are incongruent with constituent preferences, and to reinforce policy choices that are congruent. We conduct a within‐subjects field experiment using U.S. senators as subjects to test this hypothesis. We then conduct a between‐subjects survey experiment of ordinary people to see how they react to the explanatory strategies used by senators in the field experiment. We find that most senators tailor their explanations to their audiences, and that these tailored explanations are effective at currying support—especially among people who disagree with the legislators’ roll‐call positions.  相似文献

Disasters such as flash flooding, mass shootings, and train and airplane accidents involving large numbers of victims produce significant opportunity for research in the biosciences. This opportunity exists in the extreme tails of life events, however, during which decisions about life and death, valuing and foregoing, speed and patience, trust and distrust, are tested simultaneously and abundantly. The press and urgency of these scenarios may also challenge the ability of researchers to comprehensively deliver information about the purposes of a study, risks, benefits, and alternatives. Under these circumstances, we argue that acquiring consent for the immediate use of data that are not time sensitive represents a gap in the protection of human study participants. In response, we offer a two-tiered model of consent that allows for data collected in real-time to be held in escrow until the acute post-disaster window has closed. Such a model not only respects the fundamental tenet of consent in research, but also enables such research to take place in an ethically defensible manner.  相似文献

In forensics, bloodstains on dark fabrics might be invisible for the naked eye. Although several visualization, presumptive, and confirmatory blood tests have been developed, all have one or more disadvantages, especially on DNA analysis. We report here the use of a visualization assay that can visually detect blood drops up to 1/20 dilution. In this assay, the fabric is placed between two wet filter papers and covered by glass surfaces on both sides. Pressure is applied on the glass surfaces in which bloodstains transfer onto the filter papers through capillary forces. Detected stains can be tested with other more sensitive presumptive blood tests performed on the filter paper. Even more, DNA analysis can be performed on the transferred bloodstains. The presented visualization assay is easy to perform, extremely cheap, requires little hands on time, and does not affect bloodstain pattern analysis.  相似文献

In Latin America, and particularly Brazil, inequality and social exclusion continue to plague the quality of democracy despite two decades of transition and consolidation. Still, in Brazil, the Workers' Party has been remarkably successful over the past decade, explicitly addressing the problem of social exclusion and 'incomplete citizenship'. This paper provides an analysis of the case of Porto Alegre covering the four Workers' Party municipal administrations from 1989 to the present in order to assess the significance of social incorporation and citizenship for the quality of democracy in Brazil. The paper discusses some conceptual notions that are relevant for the question of democracy in Brazil, particularly the role of citizenship and civil society in 'deepening' democracy. Then the paper goes into the evolution and dynamics of Porto Alegre's system of 'participatory budgeting'. The paper's assessment of this experience with respect to its performance, depth and robustness shows that 'participatory budgeting' has had positive effects with respect to the provision of public goods services, the quality of governance, and citizens' participation in what is seen as a new 'public space' shared by the local state and grass roots organisations. The paper concludes by relating the case experience to the question of citizenship, civil society and democracy and by reflecting upon its wider implications for the current and future quality of democracy in Brazil.  相似文献

The Human Genome Project showed that there is significant genetic variation within the population. Current research is accumulating large databases that may reveal genetic variations associated with disease or health risks, even if not intended as part of the study design. These incidental findings create legal, ethical, and financial challenges for researchers. Current federal and international guidelines are not adequate. Plans for dealing with incidental findings need to be established in the study design and reviewed and approved by the Institutional Review Board.  相似文献
