强耦合氢等离子体中Be~（3＋）的结构和辐射性质研究

采用离子球模型研究了强耦合氢等离子体中杂质Be3＋的原子结构和光谱性质随离子球大小的变化规律.结果表明,强耦合等离子体的屏蔽效应对其中的原子结构和光谱影响很大,而且不同模型给出的结果有很大的差别;在离子球模型下,类氢的轨道电离能随着屏蔽效应的增强而单调减小,轨道的简并度解除,但是随着屏蔽效应的增强,轨道将二次简并,轨道能级关于角动量发生发转;不同主量子数n两能级之间辐射的光谱随着屏蔽效应的增强先红移而后蓝移,在非相对论情况下,屏蔽效应引起同n轨道能级劈裂,辐射出新的光谱,该光谱随着等离子体效应的增强先蓝移后红移,经过再次简并后继续蓝移,直到不再辐射出光谱为止;轨道之间的重叠积分由于等离子体屏蔽效应先减小而后增大,从而振子强度随着等离子体屏蔽效应的增强先减小而后增大.目前的计算数据与可查的数据非常符合.     

广西金融发展与经济增长关系的实证研究：1978-2012

利用广西1978—2012年地区生产总值、银行贷款和银行存款的时间序列数据，建立了三者之间动态关系的向量自回归模型（VAR）。研究结果显示：银行贷款和银行存款对地区经济增长有促进作用，并且银行贷款的影响大于银行存款的影响；在10％的显著水平上，地区生产总值与银行贷款构成双向Granger因果关系；在5％的显著水平上，银行存款与地区生产总值之间只存在单向Granger因果关系。据此，提出了广西金融改革发展的政策建议。     

Food safety recall effects across meat products and regions

Food safety is one of the key issues for the international meat market. As a major meat exporter, few things facing the U.S. meat industry in recent years have garnered more attention than food safety events and policies. The impacts of Food Safety Inspection Services (FSIS) recalls on United States consumer meat demand are estimated using monthly grocery-scanner data identifying effects across products, geographic regions, and recall type. Results suggest beef E. coli recalls significantly reduce the demand for recalled ground beef contemporaneously among most, but not all, regions in the United States. Evidence of heterogeneity in demand impacts across regions and products is provided for the first time. Domestic and international implications for policy makers, industry leaders, and researchers are discussed.     

Heterogeneous returns to chemical fertilizer at the intensive margins: Insights from Nepal

Increased fertilizer use is considered important for agricultural development in low-income countries. Promoting increased use of chemical fertilizer by lowering its price may be ineffective if demand is price inelastic. In theory, the price elasticity of demand depends on the returns to its use, but the evidence is scarce. Furthermore, while returns are often estimated for small changes in chemical fertilizer use, returns to larger changes in its use (intensive margins) are less understood. Through the inter-zonal comparisons in Nepal, we provide indicative evidence that greater returns to chemical fertilizer are associated with greater price elasticities of demand. Moreover, the evidence suggests that returns at the intensive margins, rather than returns to small changes, may largely account for inter-zonal differences in returns to chemical fertilizer within Nepal. The results suggest that better understanding the returns at the intensive margins is critical for effective agricultural inputs policies in developing countries.     

福利旅游的类型学分析及基于分类的运作模式研究

福利旅游作为一种促进社会公众,特别是弱势群体参与旅游活动的重要手段,在西方各国已经有了较好的实践。随着中国旅游业的发展,在追求旅游经济效益的同时,让公民更公平地参与到旅游活动中来,成为旅游发展中的重要任务。通过对国内外福利旅游理论和实践的分析,以类型学的方法,提出了福利旅游的分类框架。并在福利旅游实施者和受益者构成的分类框架下,探讨了福利旅游可能的运作模式,为如何在中国实施福利旅游提供了思路。     

So,you want to be an entrepreneur? Lessons from the Entrepreneurship Bootcamp for Veterans with Disabilities

Based on helping dozens of military veterans refine their ideas for starting a business, we identify and discuss a series of potential pitfalls that aspiring entrepreneurs—veterans and civilians alike—must avoid in order to be successful. Potential entrepreneurs must not confuse the pursuit of hobbies and self-employment with the act of creating a business. People who wish to build a business around public speaking or consulting need to firmly establish why customers should be willing to pay for their advice. Individuals that seek to develop a new non-profit organization must have a viable value proposition even though they are not pursing a profit motive. Overall, the entrepreneurial ventures that are most likely to succeed are those that (1) are based on a sustainable business model, (2) leverage the entrepreneur's unique experiences and attributes, and (3) are built around a process or system that enables the venture to prosper even if the entrepreneur leaves the venture.     

Economic consequences of war: Evidence from Sri Lanka

We propose a theoretical and econometric framework to evaluate the impact of war on economic growth of a developing country with an open economy. The theoretical framework encompasses both the neoclassical and endogenous growth models. We test this framework using Sri Lankan data. The war had significant and negative effects both in the short and long-run (annual average of 9% of GDP). High returns from investment in physical capital did not translate in sizable positive externalities. Only short-run significant effects of openness on growth are found. Inconsistent politically driven policies towards openness are the likely reason.     

Sustainable Entrepreneurship and B Corps

Sustainable entrepreneurship contributes to solving social and environmental problems through the means of successful for‐profit businesses. This paper contributes to understanding how sustainable entrepreneurship is implemented by exploring an emerging new form of business, ‘B Corps’, that employs market tactics to address social and environmental issues. Through interviewing 14 B Corps, the exploratory research study found that B Corps treat profit as a means to achieve positive societal ends, they regard the B Corp model as a tool for change, the B Corp model provides a common collective identity for internal and external validation, they are focused on societal impact rather than maximizing profits and they attempt to legitimate this form of sustainable entrepreneurship by influencing the business community and government officials.

基于生态位适宜度的区域创新生态系统与创新效率研究

由于区域内创新资源的有限性，区域创新生态系统中创新主体生态位之间的重叠程度对创新效率的影响愈发的显著，基于此本文运用生态位适宜度评价模型对我国30个省市 2011~2015 年的创新生态系统适宜度水平进行了测度，并分别与运用超效率数据包络分析法所测得的区域知识创新效率和产品创新效率进行了面板数据的回归分析。结果显示，区域创新生态系统的生态位适宜度对两个阶段的创新效率均具有正向的相关关系，但这种影响只具有短期的时间维度，并不存在两年及以上的相互作用。区域创新生态系统的对外开放会对产品创新阶段的创新效率产生负面影响，同时会促进知识创新阶段创新效率的提高。最后，在协调系统内部各生态位之间的发展关系时，应注重区域内经济发展水平对两个阶段创新效率的促进作用。
