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。     

Growing Up in Times of War: Unaccompanied Refugee Minors’ Assumptions About the World and Themselves

Abstract

The idea that assumptions about the world and the self can be damaged through traumatic experiences has proven to be useful in understanding posttraumatic reactions. This study investigated the World Assumptions of middle-eastern unaccompanied refugee minors (URMs) to contribute to a culturally sensitive theoretical perspective. Semistructured interviews were conducted and analyzed using inductive category development. All assumed aspects of World Assumptions—benevolence, meaningfulness, and self-worth—were found in the participants’ statements. Regarding meaningfulness, we detected a new subcategory, the principle of a metaphysical plan, which has implications for the mechanism by which religiosity protects World Assumptions in war-torn regions.     

The use of 3D visualization for sustainable tourism planning

This paper describes the results of using 3D visualization (3DV) in sustainable tourism planning (STP) during the Comcot project in Estonia. Organizers were interviewed on the characteristics of 3DV for STP and on how participants were involved in discourse using 3DV. The study describes experiences from the Setu, Maidla, and Võrtsjärv lake regions of Estonia. The content analysis of the interviews suggested that the precise selection of visualization objects, detalization levels, and user interface characteristics may significantly influence the quality of STP sessions and help to optimize time, financial, and human resources allocated for a project. The coherent design of the 3DV tool and the neutral moderator positively affect the level of participant involvement in STP and support a trusted platform for community decision making.

Trade and Industrial Policy as Levers for Sustainable Energy Technology Adoption? Experiences from Urban Latin America

Debates abound regarding the link between trade and industrial policy and the adoption of sustainable energy technologies in developing countries. Some purport that open trade regimes support technology diffusion, while others indicate that more interventionist regimes are more conducive. This paper uses empirical evidence from Mexico City and São Paulo to argue that sustainable energy technology uptake can be more prevalent in settings with partially open trade policy regimes. These regimes have afforded countries more opportunities to develop local capabilities, which, in turn, has had knock‐on effects on sustainable energy technology uptake. Specifically, having more local technology sources (equipment, expertise) brought quicker access to these technologies, created more perceptions of technology “ownership,” fostered more effective mobilization, and helped create well‐established standards, which in turn contributed positively to sustainable energy technology uptake, while taxes and tariffs were less influential.     

Alleviating poverty through resource provision: The case of a South African agricultural project

The article documents the findings of a qualitative study that assessed the sustainability of providing resources for poverty alleviation. It argues that access to resources does not assure livelihood security. The study also argues that the ability to sustain resources, rather than merely facilitating access, assures poverty alleviation and livelihood security. Using a qualitative research method and the sustainable livelihoods approach, the article assesses the activities and performance of a small group of women in a government-sponsored agricultural project. The findings reveal that exited projects struggle to sustain themselves and that assetting alone – without skills, capacity, sense of ownership and a clear focus – does not yield the sustainability necessary for poverty alleviation. The conclusion is made that although resources are a necessary first step towards poverty alleviation, sustainable resource management should be highly valued in the process. The article recommends that agriculture-based development projects not be seen as the only option for the rural poor, as knowledge of farming is indeed crucial.     

Are lions democrats? The impact of democratization on economic growth in Africa, 1980–2010

If we look back at the past two decades, timing seems to point to a close connection between democratic reforms and economic growth in sub-Saharan states. Most countries in the area introduced multiparty politics and made dramatic – if incomplete – democratic progress between 1990 and 1994. Quite strikingly, it is exactly from 1994 to 1995 (and particularly from 2000) that the region began to undergo a period of significant economic progress. Because of the undeniable temporal sequence experienced in the region – that is, first political reforms, then economic growth – some observers pointed to a nexus between democratic progress and economic performance. But is there evidence in support of a causal relationship? As of today, no empirical research has been conducted on the democracy–growth nexus in the early twenty-first century's so-called “emerging Africa”. To fill this gap, we discuss the different arguments claiming an economic advantage of democracies, we present our theoretical framework and carry out an empirical analysis of the growth impact of political regimes in 43 sub-Saharan states for the entire 1980–2010 period. Our findings confirm that African countries, many of which had long suffered the combination of authoritarian rule and predatory practices, derived some economic dividends from democratic progress.     

GFAP和VEGF在创伤性脑损伤中表达的研究进展

创伤性脑损伤是世界上导致死亡及残疾的主要原因之一。检测对中枢神经系统损伤有高度特异性和敏感性的生物标志物,可以在一定程度上反映损伤情况。胶质纤维酸性蛋白与血管内皮生长因子均可作为颅脑损伤的生物学标记物,其表达变化规律、峰值出现时间,与创伤性脑损伤的严重程度及损伤时间的推断密切相关,对于法医病理学具有重大意义。该文对胶质纤维酸性蛋白与血管内皮生长因子的分子生物学特性及其在创伤性脑损伤中的表达进行综述。     

建设生态文明，实现社会可持续发展

中共十七大报告明确提出“生态文明”的概念,并将生态文明作为全面建设小康社会的一个目标要求。中国进行生态文明建设不仅具有很强的理论依据,而且是解决经济高速增长过程中诸多问题、实现经济社会可持续发展的内在需要。因此,一要加强生态文明教育和宣传,在全社会树立生态文明观念;二要加快转变经济发展方式,加强能源资源节约和生态环境保护;三要完善环保的法律和政策体系,为生态文明建设提供法律和政策保障。
