The influence of risk preferences,knowledge, land consolidation,and landscape diversification on pesticide use

Researchers have spent substantial effort to identify factors influencing pesticide use intensity. However, few studies have compared the relative importance of these factors. This study examines four categories of factors that potentially influence farmers’ pesticide use decisions by evaluating incentivized experiment data, farm survey data, and remote sensing data in China. Our results suggest that land diversification has the largest effect on farmers’ pesticide use. Compared with the most rice-intensive landscape type, less rice-intensive systems cause farmers to spray less on middle rice. Heavy pesticide use intensity is associated with land fragmentation as small-scale farms still dominate crop production. Farmers’ integrated pest management knowledge has significant effects on pesticide use. We also find that loss and ambiguity preferences, rather than risk preferences, are more likely to affect pesticide use intensity.     

民办高校党务干部队伍状况对党建工作的影响及对策——以广东省S学院为例

民办高校党务干部队伍作为学校党建工作实施者,其队伍状况在很大程度上将直接影到党建工作质量和水平,进而影响到人才培养质量。目前民办高校党务干部队伍普遍存在队伍结构失衡,党务干部身兼多职,重业务知识学习,轻理论武装,重专业技能培训轻党务能力提升等状况。要改善现状,必须做到:一是加强制度建设,狠抓贯彻落实,争取上层支持;二是加强业务培训,鼓励开展党建工作研究;三是加强党建工作信息化建设,打造符合时代需求的党务干部队伍;四是引进激励措施,提高工作积极性。     

秦腔剧本现代化的探索——以陈彦三部曲为研究对象

"八百里秦川尘土飞扬,三千万楞娃高吼秦腔",秦腔以其恢弘的气势和豪迈粗犷的演唱方式在陕西人的心中深深地扎下了根,没事吼一嗓子秦腔是陕西人茶余饭后的一项娱乐活动,由此可见秦腔在陕西人心中可见一斑。然而随着时代的现代化进程的脚步秦腔这个传承数千年的地方戏却越来越被现代人所遗忘,秦腔的现代化进程迫在眉睫。而如何现代化却成为了一个难题,是全面现代化还是部分现代化?是保留还是抛弃?……而作为秦腔现代化最重要的一个环节,剧本的现代化又从哪几个方面入手?本文将从剧本现代化的各方面进行探索,从而为秦腔的现代化这个浩大的工程尽上一点绵薄之力。     

The Sarbanes‐Oxley Act and the Choice of Bond Market by Foreign Firms

This paper examines the economic impact of the Sarbanes‐Oxley Act (SOX) by studying foreign firms’ choice of whether to issue bonds in the U.S. public bond market or elsewhere before and after the law's enactment in 2002. After controlling for firm characteristics, bond features, home‐country attributes, and market conditions, I find that foreign firms rely less on the U.S. public bond market after SOX. Additionally, some determinants of choosing the U.S. public bond market have changed since the passage of SOX: firms listing equities on U.S. stock exchanges, adopting International Financial Reporting Standards (IFRS), and doing large bond issuances are more likely to choose this market in the post‐SOX period than in the pre‐SOX period. Overall, these results are consistent with a shift in the expected costs and benefits of choosing the U.S. public bond market following SOX. This paper provides the first evidence about how SOX influences debt financing decisions and alters capital flows across international bond markets.     

阻断性压力源与工作-家庭冲突:谦卑和学习目标导向的调节作用

基于资源保存理论和压力交互模型,本研究探讨了阻断性压力源对工作-家庭冲突的影响及其边界条件.对国内120名企业员工的数据分析结果表明,阻断性压力源正向影响工作-家庭冲突,除此之外,谦卑和学习目标导向共同调节了阻断性压力源和工作-家庭冲突之间的关系,具体地,当谦卑和学习目标导向均高的时候,阻断性压力源与工作-家庭冲突之间的正向关系最弱;相反,对于谦卑和学习目标导向均低的个体来说,阻断性压力源对工作-家庭冲突的正向影响最强.

Can negative interest rates really affect option pricing? Empirical evidence from an explicitly solvable stochastic volatility model

The profound financial crisis generated by the collapse of Lehman Brothers and the European sovereign debt crisis in 2011 have caused negative values of government bond yields both in the USA and in the EURO area. This paper investigates whether the use of models which allow for negative interest rates can improve option pricing and implied volatility forecasting. This is done with special attention to foreign exchange and index options. To this end, we carried out an empirical analysis on the prices of call and put options on the US S&P 500 index and Eurodollar futures using a generalization of the Heston model in the stochastic interest rate framework. Specifically, the dynamics of the option’s underlying asset is described by two factors: a stochastic variance and a stochastic interest rate. The volatility is not allowed to be negative, but the interest rate is. Explicit formulas for the transition probability density function and moments are derived. These formulas are used to estimate the model parameters efficiently. Three empirical analyses are illustrated. The first two show that the use of models which allow for negative interest rates can efficiently reproduce implied volatility and forecast option prices (i.e. S&P index and foreign exchange options). The last studies how the US three-month government bond yield affects the US S&P 500 index.     

Shanxi Merchants’ Multilevel Financial System in Ming and Qing Dynasties,China

In the Ming and Qing Dynasties (1368–1911), China saw rapid development in industrial and commercial sectors. Over this period, a group of merchants originating from the inland province of Shanxi gradually built a multilevel financial system and became leaders in China’s banking sector. The system of financial institutions they established (pawnshops, seal shops, money shops, loan banks, and draft banks) each had a unique business model, with specific target client group and carefully designed risk management. They were also interconnected to allow for flexible capital flows, contributing to the fast economic growth in this period. Nevertheless, the traditional system also had limitations, leading to its replacement by modern banks eventually.
