Organisations involved in delivering international democracy assistance are engaging increasingly with questions about how to assess their activities. A double shift in the terms of reference, from the ex post evaluation of assistance projects or programmes to ex ante appraisal of the broader democracy promotion strategies, could make democracy promotion more effective. This does not mean abandoning the former; on the contrary its status would be enhanced. Improving the chain of learning that leads from assistance evaluations to the formulation of promotion strategies could improve decision-making over how and whether to promote democracy abroad. Because strategies for democracy promotion are constitutive of the political relationship with countries, different strategies have different implications for the possibilities of political self-determination. For that reason and because democratisation and hence effective democracy promotion may be beneficial for human development, international peace and national security, strategies that reflect informed appraisal would be an improvement on a defective status quo. The challenges include: more systematic data gathering; innovative ways of comparing the various democracy promotion options; and institutional changes that connect the research findings to the high politics of policy-making.  相似文献

Using panel data for 143 countries over the period 1973–2002, this paper empirically analyzes the influence of US aid on voting patterns in the UN General Assembly. We use disaggregated aid data to account for the fact that various forms of aid may differ in their ability to induce political support by recipients. We obtain strong evidence that US aid buys voting compliance in the Assembly. More specifically, our results suggest that general budget support and grants are the major aid categories by which recipients have been induced to vote in line with the United States. When replicating the analysis for other G7 donors, no comparable patterns emerge.  相似文献

Negotiation training evaluation tends to be short-term, aspectual and piecemeal; evaluations often focus on only one or two salient outcomes of training. This essay presents a model for negotiation training evaluation research that offers a broad conceptualization of the hypothesized individual and group-level effects of training in collaborative negotiation. The model assesses change at the individual level in conflict-related cognitions, attitudes, affect and behaviors; and at the group level in conflict outcomes and work climate. The Negotiation Evaluation Survey (NES), a time-delayed, multi-source feedback approach to assessment and development, is presented as a means of addressing some of the conceptual and methodological problems inherent in more common methods of training evaluation. An illustrative assessment of one model of collaborative negotiation training for adults, the Coleman/Raider Model, is presented. The results, implications, and future research challenges are discussed.  相似文献

The purpose of this article is to explain how public managers can influence the mix of institutional logics in a process of organizational change. To do this, the concept of post-transformational leadership is related to institutional logics. The article is based on a case study of the Danish Crime Prevention Council. The study shows how post-transformative leaders are urged to move from strategies of collaboration to strategies of manipulation, hypocrisy, and the hijacking of institutional logics.  相似文献

With deeper integration into the global economy and expanded penetration by multinational firms and other nonChinese actors following accession to the WTO, skills in bureaucratic entrepreneurship are not likely to be sufficient by themselves to bring about China’s sustainable development. In today’s interdependent and highly competitive trade, economic-cooperation, and resource-limited environment, sustainable development requires that subnational managers also possess transnational competence in collaborating with, negotiating with, and transforming foreign counterparts. However, survey research among Chinese executives based in Shanghai revealed that only a small proportion of the reporting current and future managers recognized the growing importance for China of an interculturally competent workforce. Without increased attention to enhancing the transnational competence of government and state-enterprise managers, peaceful and ecologically sound development will be difficult to sustain given the demands of multinational production chains, global resource constraints, and the challenges involved in managing transnational relations in the interest of China’s long-term economic progress.

Hacking trauma is prevalent in forensic cases involving genocide and dismemberment, but research into the identification of this type of trauma is lacking. The present study examines characteristics of hacking and blunt force skeletal trauma in order to determine if there is a point at which blunt force trauma becomes distinguishable from hacking trauma. Ten implements with a range of blade angles (i.e., the striking surface of the implement) were used in conjunction with a controlled-force hacking device to impact 100 limb bones of white-tailed deer (Odocoileus virginianus). Observations of the trauma included the occurrence and degree of fragmentation, the entrance widths of the impacts, and composite scores of six hacking characteristics, especially the distinctive V-shaped kerf. ANOVA tests and regression analyses were used to assess the relationships between these characteristics and the blade angles. A significant relationship (p-value = 0.011) was found between the composite hacking scores and the blade angles, indicating that blunt force and hacking trauma can be distinguished. The entrance widths of the impacts exhibited a significant relationship with the blade angles (p-value = 0.037). There was also a significant relationship between the visibility of a V-shaped kerf in the bones (p-value = 0.003), with visibility decreasing around the 60° blade angle. These data should assist in establishing guidelines to differentiate hacking and blunt force skeletal trauma in cases where the implement is on a spectrum between sharp and blunt.  相似文献

Clinicians tend to overestimate their ability to recognize feigning behavior in psychiatric patients, especially if it concerns patients who have been admitted for observation. Feigning can be either externally motivated (e.g., for financial compensation, known as malingering) or internally motivated (e.g., to assume the “sick role,” known as factitious disorder). Persistent presentation of severe symptoms is usually associated with the factitious disorder. We present two patients with strong external incentives who consistently and convincingly feigned severe psychiatric symptoms during a protracted period of inpatient observation in a specialized center; both were engaged in a procedure for medical asylum. The first case presented with the clinical picture of a psychotic depression with severe motor symptoms, and the second case showed symptoms of a chronic post-traumatic stress disorder with secondary psychotic symptoms. Both cases were thoroughly investigated but feigning was overlooked, and unnecessary and harmful treatment interventions were given. To prevent iatrogenic damage, we recommend a critical attitude that takes malingering as an option into account in settings where patients are often involved in high stake legal procedures. A clinical sign that might indicate feigning is therapy-resistant symptoms. To rule out feigning a comprehensive, multimethod approach is required, but an active stance toward collateral information is essential. Specialized psychological tests may be useful for preliminary screening, but for their use in culturally diverse populations as in refugee mental health more research is needed.  相似文献

Sharp force trauma is a common homicide method. The weapon is typically a knife, which is easily accessible and does not require special skills. We have analyzed all 471 sharp force homicides in Denmark during 1992–2016 with special focus on aspects that are relevant to forensic pathologists, including the distribution of wounds and organ injuries. Most homicides were committed inside with a kitchen knife. The front left thorax was the most common area to be affected by sharp force trauma. In 18.9% of the victims, there was only one sharp injury, the majority on the thorax. The most common trajectory for stab wounds was directly posterior with no deviation to the sides or up/down followed by directly anterior. The heart (including pericardium) and lungs (including hemo- and pneumothorax) had injuries in more than 75% of the victims. 67% of victims were males. Female victims had more sharp force injuries and defense wounds than male victims. Most females were killed in domestic homicides (73.7%), most commonly in partner killings (56.4%). In contrast, many male victims were killed in a setting of nightlife/intoxication (34.0%) most by a friend/acquaintance delivering a few stab wounds. The results clearly show strong sex differences in both victims and offenders. This could be useful for shaping policies and public opinion, and as a route for understanding the developments in interpersonal violence. In the narrow setting of death investigation, our results will provide an evidence-based approach to understanding the injury patterns in sharp force homicide.  相似文献

This study describes the performance of handheld Raman devices for determining whether suspect pharmaceutical tablets declared to contain controlled substances were consistent with authentic (CWA) or not consistent with authentic (NCWA) tablets using a simple, rapid, field-friendly method capable of being used by nonexperts. Twenty-five authentic products and 84 known NCWA tablets were examined using three “parent” devices for a total of 327 analyses. On average, the parent devices yielded a true pass rate of 100%, a true fail rate of 98.4%, a false pass rate of 1.6%, and a false fail rate of 0%. The methods/libraries were then transferred to 13 identical “daughter” devices, which were used to examine 10 suspect finished dosage forms in duplicate (six known NCWA tablets and four authentic tablets) for a total of 260 measurements. On average, the daughter devices had a true pass rate of 100%, a true fail rate of 95.5%, a false pass rate of 4.5%, and a false fail rate of 0.0%. These data demonstrate that the parent–daughter electronic transfer method was successful, which permits the ability to develop methods in the laboratory that can be seamlessly pushed out to field devices. The methods can then be used to (i) prioritize samples for additional testing using other more time-consuming laboratory-based techniques needed to detect and quantify active ingredients and (ii) help support the interdiction of dangerous tablets at ports of entry, thereby preventing them from reaching the supply chain.  相似文献
