Open governance requirements are designed to improve accountability, which implies that transparent governments are more trustworthy stewards of their publicly invested power. However, transparency may also reduce institutional effectiveness and inhibit political compromise, diminishing the capacity to manage resources responsibly. We assess empirical support for these competing perspectives in the context of American state legislatures, many of which have become exempt from state sunshine laws in recent decades. We leverage variation in the timing of these legislative exemptions to identify the effect of removing transparency in a crucial governing institution on investors’ risk perceptions of states’ general obligation bonds. Our analysis of these data during the period 1995–2010 suggests that removing legislative transparency reduces state credit risk. We conclude that while openness in government may be normatively desirable, shielding legislative proceedings from public view may actually be better for states’ debt repayment capacity, improving their overall fiscal health.  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.

World history has known areas of relative isolation and areas of high intensity of cultural interaction. The Mediterranean Sea, the Silk Road or the Straits of Malacca can be cited as such crucial contact zones. Within these areas, centres sprung up that served as interfaces between cultures and societies. These “hubs” as we would like to call them, emerged at various points throughout the contact zones, rose to prominence and submerged into oblivion due to a variety of natural calamities or political fortunes. This paper assesses the rise and fall of trade and knowledge hubs along the Straits of Malacca from before colonialisation until today. Historical hubs of maritime trade and religiosity today increasingly establish themselves as educational and knowledge hubs. This leads us to speak of the Straits of Malacca as a chain of—not pearls—but knowledge hubs with Singapore as the knowledge hub in the region shining the brightest of all, as the data suggest. We aim to conceptually grasp this development by suggesting a model or at least a hypothesis about the rise and movement of knowledge hubs in general.

The quality of deliberative conversations are dependent on citizens compliance with deliberative norms yet there is a lack of methods to assess norm compliance in discussions. Here, the psychological construct of complexity of thinking is claimed to conceptually correspond to the deliberative conversational ideal and adopted as a measurement of deliberative norm compliance. The hypothesis that citizens' complexity of thinking increases as a result of participation in deliberative conversations was tested in a minipublic case study in Sweden. Participants' complexity of thinking was assessed before and after deliberation by responding to an open‐ended question about the topic of debate. Manual coding was used to rate participants integrative complexity. The result confirms the hypothesis, which serves as an indicator of deliberative quality. The study also demonstrates that women get higher increases in complexity, as do highly agreeable individuals and those who hold more liberal views. The findings demonstrate the potential usefulness of integrative complexity as a measurement of deliberative quality.  相似文献

The U.S. electric power sector has experienced a substantial shift of the generation mix since the turn of the century, moving from heavy reliance on coal‐powered generation to one drawing more from natural gas and, more recently, renewables. This transition has been forged by a mix of macroeconomic factors (recession and recovery); technological breakthroughs (horizontal drilling coupled with hydraulic fracturing; improvements in natural gas plant efficiency); clean energy policies at federal, state, and local levels of government; and private sector demands for carbon‐free energy sources. These factors have combined to reduce carbon emissions from electric power generation substantially this century. In this article we examine the extent of this transition, its causes, as well as the distinct American institutional factors steering it, including energy and environmental federalism, electoral politics, and the political economy of clean energy policy enactment and resistance.  相似文献

Postmortem computed tomography (PMCT) is integrated into the evaluation of decedents in several American medical examiner offices and medicolegal death investigative centers in many other countries. We retrospectively investigated the value of PMCT in a series of firearm homicide cases from a statewide centralized medical examiner’s office that occurred during 2016. Autopsies were performed or supervised by board-certified forensic pathologists who reviewed the PMCT scans prior to autopsy. PMCT scans were re-evaluated by a forensic radiologist blinded to the autopsy findings and scored by body region (head–neck, thoracoabdominal, and extremities). Injury discrepancies were scored using a modified Goldman classification and analyzed with McNemar’s test. We included 60 males and 20 females (median age 31 years, range 3–73). Based on PMCT, 56 (79.1%) cases had injuries relevant to the cause of death in a single body region (24 head–neck region, 32 thoracoabdominal region). Out of these 56 cases, 9 had a missed major diagnosis by PMCT outside that region, including 6 extremity injuries visible during standard external examination. Yet all had evident lethal firearm injury. We showed that PMCT identifies major firearm injuries in homicide victims and excludes injuries related to the cause of death in other regions when a single body region is injured. Although PMCT has a known limited sensitivity for soft tissue and vascular pathology, it can be combined with external examination to potentially reduce or focus dissections in some of these cases depending on the circumstances and medicolegal needs.  相似文献

When a bullet punctures a surface, it leaves behind a bullet impact, which can be analyzed in order to determine the origin and trajectory path from which a bullet was discharged using many different scientific methods to reconstruct a shooting scene. The purpose of the research was to test the accuracy and repeatability of reconstructing the impact angle of single bullet impacts using the ellipse method. The research was conducted by firing various calibers of ammunition into drywall panels positioned at varying angles of incidence from 88° until ricochet occurred. This was done in order to determine which caliber type and angle of incidence are most accurate and precise for reconstructing a shooting scene. The study examined four caliber types fired into drywall panels, with 5 repeated shots for each of the 11 angles of incidence (n = 220). Furthermore, 31 participants partook in the study to estimate a bullet impact angle of incidence utilizing the ellipse method. The results show that the best performance (accuracy and repeatability) is seen with the measurements of the 0.45 caliber ammunition. When angle of incidences is low (<64°), the performance (accuracy and repeatability) was seen to be better in all caliber ammunitions. Overall, the data provided for single bullet impacts deposited in drywall show that the ellipse method is useful in providing measurements for most crime scene reconstruction purposes and has also demonstrated that results vary depending on the type of ammunition, firearm, and angle of incidence being examined.  相似文献
