Using a multivariate framework and the most recently available data that include numerous African countries, this investigation has produced the first extensive statistical evaluation of China’s image in Africa based on China’s various economic relations with Africa, including aid, trade, FDI and contracts. We find that China’s economic development assistance, contracts, and to some degree, trade with African countries contribute to a positive image of China in Africa. In addition, we find that people in African countries of a smaller population, poorer livelihood, less open economy, and better governance tend to have positive views of China’s political and economic influence. With the implementation of the Belt and Road Initiative, Chinese economic activities in recipient countries have been increasing. The implications of this research shed light on how BRI may be received in the host countries and the likelihood of its success or failure.

Taking enviornmental management in Guangzhou as an example, this article explores the theory and practice of Communist China's idea of “environmental management by law.” Based on the Guangzhou experience, it argues that environmental management by law in China is mainly an administrative system of environmental management which takes law strictly as a tool for efficient and effective environmental protection. This system is operated on the principle of ‘rule by law’, and is the antithesis of the Maoist practice of “rule by person.” Contrary to its Western counterpart, China's environmental management system is built on a state‐centered conception of administrative law instead of a ‘right‐centered’ one which is the core of the ‘rule of law’ tradition.  相似文献

The search for the optimal size of political systems is one of the most enduring in political thought. Given the validity of arguments for and against small units, one might expect variation in rearrangements of unit sizes. However, the reform trend is uniform: units, often at the local level, are amalgamated to harvest scale effects. The purpose of this article is to evaluate the argument on economies of scale in the economic costs of running political systems. Our testing ground is a recent Danish reform. It allows us to avoid endogeneity problems often facing researchers of size reforms. The reform was directed by the central government and constitutes an exogenous shock to 239 municipalities, whereas 32 municipalities were left untouched. We thus have a quasi‐experiment with pre‐ and posttreatment observations for both an experiment and a control group. Our findings show that scale effects, measured as administrative costs per inhabitant, are considerable.  相似文献

Collection and especially analysis of open‐ended survey responses are relatively rare in the discipline and when conducted are almost exclusively done through human coding. We present an alternative, semiautomated approach, the structural topic model (STM) (Roberts, Stewart, and Airoldi 2013; Roberts et al. 2013), that draws on recent developments in machine learning based analysis of textual data. A crucial contribution of the method is that it incorporates information about the document, such as the author's gender, political affiliation, and treatment assignment (if an experimental study). This article focuses on how the STM is helpful for survey researchers and experimentalists. The STM makes analyzing open‐ended responses easier, more revealing, and capable of being used to estimate treatment effects. We illustrate these innovations with analysis of text from surveys and experiments.  相似文献

Recent studies analyze how citizens update their perceptions of parties’ left‐right positions in response to new political information. We extend this research to consider the issue of European integration, and we report theoretical and empirical analyses that citizens do not update their perceptions of parties’ positions in response to election manifestos, but that citizens’ perceptions of parties’ positions do track political experts’ perceptions of these positions, and, moreover, that it is party supporters who disproportionately perceive their preferred party's policy shifts. Given that experts plausibly consider a wide range of information, these findings imply that citizens weigh the wider informational environment when assessing parties’ positions. We also present evidence that citizens’ perceptions of party position shifts matter, in that they drive partisan sorting in the mass public.  相似文献

Does the increasing politicisation of Europe signify a step towards the legitimation of the Union? This could be the case if the increased public intensity of debate and polarisation of opinion brought about by politicisation do not fragment the audience and if arguments presented in public are sufficiently clear about the desired nature of the polity. To answer this question, the focus of this article is on dynamic contestation in the public sphere using original data of news platforms and political blogs in 12 EU Member States and transnational websites during the European Parliament election campaign of 2009. The results are, first, that diffuse eurosceptic evaluations dominate public debates despite large variation in the intensity of debate across Member States. Second, a majority of evaluations made, particularly those by citizens leaving comments online, are negative in all countries included in this study. A gap between elites and citizens persists, but it appears less pronounced than often proclaimed in the literature. And third, democracy is a primary concern in EU polity contestation, especially for those evaluating the EU negatively. Although little evidence is found of a fragmentation of audiences, the prominence of diffuse euroscepticism poses a major challenge to legitimation of the Union.  相似文献

CT‐guided, minimally invasive needle biopsy techniques can be used to retrieve tissue or body fluid samples for histologic tissue diagnoses in forensic investigations. The purpose of this study was an evaluation of CT‐guided needle‐positioning robot B‐Rob II. To operate under CT guidance, we adopted the B‐Rob II robotic needle placement system and its workflow. The accuracy and speed of the procedure were tested on a gelatin phantom in a series of 21 biopsies. We achieved an average needle placement accuracy of 1.8 mm (±1.1 mm) using robotic assistance. The procedure required an average of 2 min 21 s. The needle placement accuracy for minimally invasive needle biopsies using the B‐Rob II biopsy robot is sufficiently accurate and fast for forensic postmortem examinations of focal organ changes. Further tests will be performed to test the feasibility of the robot for performing biopsies of focal organ changes in human bodies.  相似文献

Postmortem computed tomography (CT) is increasingly being used as a tool in forensic pathology. The exact value of postmortem imaging in detecting specific conditions has not yet been established, but in specific cases, it can be used as a diagnostic tool demonstrating findings that remain undetected during autopsy, as in this case. Pneumomediastinum and soft tissue emphysema were detected with postmortem CT in a 3‐year‐old girl after hanging. It was not found during autopsy. This radiological finding matches 3 adult cases previously described. It is assumed that in this case, the first reported in a child, hanging was the most likely cause as well. In the adult cases, it was interpreted as a vital sign; the person must have been alive to create a pressure gradient causing rupture of the alveoli. This case demonstrates one of the added values of postmortem imaging, the possibility of demonstrating findings that remain undetected during autopsy.  相似文献
