Linking past and future: cross-border development and quality of life in the Badakhshans

The 1895 Pamir Convention divided the mountainous region of Badakhshan into separate entities under Russian and British/Afghan influence, leading to a remarkable divergence in the development fortunes of a people once united by kinship. For those in today's Gorno-Badakhshan in Tajikistan, incorporation into the Soviet Union brought investments in education, health, physical infrastructure, and the economy. People living in Afghanistan's Badakhshan Province retained more political freedom but lived remotely within a feudal state where development investment was limited. In recent decades, both regions have experienced conflict that has affected their development. In this article, we use findings from quality of life assessments carried out by the Aga Khan Development Network to illustrate the stark differences between the Badakhshans. We discuss ongoing efforts to implement cross-border development programmes to improve quality of life in both Badakhshans, while noting that their success depends on a stable security environment in the region.     

中日韩FTA对产业的影响分析

随着中、日、韩贸易投资合作日益密切,区域内贸易和产业内贸易不断增加,三国关于建立自由贸易区的讨论日益激烈。分析比较三国产业竞争力,可以看到我国的整体产业竞争力与韩日相差较大,处于三国垂直型产业内贸易分工结构的低端。在这一背景下缔结三国FTA,我国的主要产业和相关企业短期内会受到一定冲击,但长远看可以促进我国产业结构升级,提高产业竞争力。为对应中日韩FTA,我国政府应改善产业环境,放宽市场限制,建立公正公平的市场机制。企业需要适应贸易投资环境的变化,从技术创新、产品差异化和管理与营销等方面加强与竞争对手的抗衡能力。     

重型颅脑损伤患者P300与智商的相关性

目的研究重型颅脑损伤患者认知功能的改变以及事件相关电位(event-related potential,ERP)中的P300成分与智商的关系。方法对40例重型颅脑损伤患者进行听觉P300检查并用中国修订韦氏成人智力全量表测定智商,另外用40例正常成年人作为对照组也进行P300的检查。结果病例组P300潜伏期较正常组明显延长(P<0.01),病例组P300的潜伏期与操作智商和总智商之间呈显著负相关(r=-0.335、-0.344,均P<0.05)。结论ERP是测定重型颅脑损伤患者认知功能变化的一项客观指标。     

Further investigations into the speed of cerebral swelling following blunt cranial trauma

An anesthetized sheep model of traumatic brain injury (TBI) has been developed to assess early changes in intracranial pressure (ICP) following closed head injury. Immediately after TBI, a transient (<10 min) hypertensive response occurred, followed by significant and prolonged systemic hypotension. ICP demonstrated a biphasic response, being seven times baseline values of 8 ± 2 mm Hg 10 min after injury, decreasing to 25 ± 2 mm Hg by 30 min, and then increasing to values exceeding 30 mm Hg by 4 h postinjury. ICP was always significantly higher than baseline values, which combined with hypotension, reduced cerebral perfusion pressure to less than 60% of normal. This early and sustained increase in ICP after craniocerebral trauma acutely alters cerebral perfusion pressure and brain oxygenation and provides a potential pathophysiological explanation for immediate clinical manifestations in humans following significant TBI.     

Humeral and femoral head diameters in recent white American skeletons

Osteologists often rely on single measurements, such as humeral and femoral head diameters, to estimate sex, especially when skeletons are incomplete. Measurements of 237 Bass Donated Collection skeletons provide a means of distinguishing white American females from males based on a modern sample: humeral head, female mean 42.1 mm, male mean 49.0 mm; and femoral head, female mean 42.2 mm, male mean 48.4 mm. Probabilities that bones at 1-mm increments came from females (p(f)) are estimated (p(m) = 1 - p(f)). An overrepresentation of one sex in the skeletons that are examined influences the probability that a bone of a certain size is from a female or male. So, probabilities are also estimated for samples consisting of an unequal number of males and females. Sample composition has its greatest effect when one sex dominates the remains that are the subject of investigation.     

糖皮质激素不良反应在医疗纠纷鉴定中引发的思考

糖皮质激素是维持生命的必需品,药理作用广,不适当的使用或长期大剂量使用可导致不良反应和并发症甚至危及生命。糖皮质激素在为患者治疗疾病的同时,也使许多患者饱受全身器官、组织受损的痛苦。由于临床存在不合理应用,不可避免地对机体产生严重的危害,有的甚至产生严重的后果,轻者掩盖病情,延误诊断,重者致感染扩散,危及生命。     

顶空GC／MS法检验血液中的硫化氢

目的建立血液中硫化氢的气相色谱质谱联用分析方法。方法取心血3mL-5mL,置于20mL顶空瓶中,加入1g氯化钠,加3mL-5mL蒸馏水,加入2mol／L盐酸1mL,加盖密封,混匀后于80℃水浴中加热20min。取液上气体0．5mL进样分析。结果在中毒死亡者的心血中检出硫化氢,保留时间参考值为3．6min。结论该方法可用于刑事案件中硫化氢的快速分析。     

新冠肺炎疫情对宏观经济的影响分析及政策建议

该文通过对比分析发现,由于疫情影响地域范围、停复工时间和经济结构等因素存在差异,新冠肺炎疫情对经济的短期影响会大于2003年非典疫情;而且,由于部分民企和居民等微观主体的抗风险能力更弱,存在传导形成次生风险的可能。因此,必须坚持疫情防控和经济托底相结合,发挥逆周期政策作用,切实降低此次疫情的负面经济影响。     

Tackling the Big Questions in Social Impact Bond Research through Comparative Approaches

Abstract

This special issue of theJournal of Comparative Policy Analysis brings together four cross-disciplinary articles representing the first concerted attempt to combine comparative approaches to extend theoretical and empirical understandings of Social Impact Bonds (SIBs). SIBs are investment-backed payment-by-results projects and have been subject to vigorous academic debate on their appropriateness and efficacy since the first SIB launched in 2010. This introduction to the special issue outlines the state of the academic literature on SIBs, identifying gaps and suggesting five big questions that do not yet have satisfactory answers: (1) What are the administrative or political problems to which SIBs respond? (2) Where and why do SIBs emerge in particular contexts? (3) What is the role of SIBs in the evidence-based policy movement? (4) Is delivering an intervention through a SIB more effective than other means and are associated costs justifiable? (5) Do SIBs catalyse wider organizational, system, or institutional changes? This introduction then summarizes the articles included in this special issue, discusses how they respond to these big questions, and suggests that further comparative research might best address remaining gaps in the literature.     

Testing the Influence of Autocratic Leadership,Democratic Leadership,and Public Service Motivation on Citizen Ratings of An Agency Head’s Performance

Abstract

Research is lacking concerning the impact of leadership styles on citizen attitudes toward the performance of government leaders. To address this gap, an online experimental survey was conducted to determine the effect of leadership styles on respondents’ perceptions regarding a fictitious superintendent’s performance in a school district. The results demonstrate that democratic leadership practices enhanced the performance reviews of the superintendent, while autocratic leadership practices decreased them. Respondents’ level of public service motivation (PSM) was also found to have a positive effect on the superintendent’s performance ratings. Furthermore, democratic leadership style moderated the relationship between PSM and the performance ratings assigned by respondents. In particular, individuals with high PSM rated the performance of democratic leaders higher as compared to individuals with low PSM. However, autocratic leadership was not found to moderate the relationship between PSM and the superintendent’s performance. These results are thoroughly discussed in the paper.
