平房仓晚籼稻谷充氮气调储藏试验

平房仓充氮储藏晚籼稻谷,先用复合膜对粮堆“五面”密闭,并有效处理工艺孔洞、工作间等漏气部位,利用移动式制氮机组通过四个进气口结合上充下排、下充上排和仓内环流或环流风机强排等工艺向粮堆充氮。近三个月氮气储藏过程中,氮气浓度维持在95％范围,杀虫率达到100％,并能有效防止害虫发生,次年害虫发生时间推迟近一个月;存粮脂肪酸值年变化量低于1．5（KOH）mg／100g,2009年充氮储藏期内脂肪酸值仅增加0．7（KOH）mg／100g;粮温变化趋势与常规储藏基本一致,但试验仓平均粮温偏高1℃～1．5℃,局部最高粮温变化提前近15d。

Women in Business in Late Nineteenth-Century Chile: Class,Marital Status,and Economic Autonomy

This article analyzes Chilean women’s entrepreneurial activity in the 1877–1908 period examining two official data sources representing different socioeconomic business niches – the national trademark registry, which represents the elite among business people, and the Santiago business license registry, which includes the non-elite. The analysis reveals an economy with women engaging increasingly in business in an expanding range of sectors. By the 1890s, women managed nearly a quarter of Santiago’s firms and 5 percent of elite firms nationally. Widows appeared overrepresented among elite businesses and underrepresented among those of the non-elite. These results suggest that institutions constraining entrepreneurship among married women were more strongly enforced among the elite than among other social classes. The evidence thus suggests that during late nineteenth century there was an increase in the economic autonomy exercised by unmarried women and widows of all socioeconomic strata, but also by married women among the non-elite.

晚清末年湖北农业改良述略

晚清末年是湖北传统农业向近代农业转变的重要阶段，侧重发展生物技术，大力发展农业教育，成为这一时期湖北农业改良方面的显著特点。在张之洞等人的积极倡导和推动下，随着西方农学思想逐步传播和商品性农业较快的发展，湖北农业无论在农作物的良种选育、推广，以及发展农业教育和传播农业知识等方面，都有了比较明显的进步，且在许多方面开风气之先。同时也为近代湖北植棉业和棉纺织业确立在国内的领先地位创造了条件。通过张之洞等人的多方努力，使处在人口不断增长和严重水患压力下的湖北农业，仍有缓慢的增长。     

对中国成为世界制造业中心的思考

在中国入世的背景下，伴随着外资的大量流入，发达国家和地区纷纷把自己的制造业基地转移到祖国大陆。从目前的状况看，廉价的劳动力资源和潜力巨大的市场是中国建成世界制造业中心的有利条件。但中国的差距和劣势也是明显的，突出表现为学习过程中的技术性后发劣势和制造性后发劣势。如果不能够克服这些后发劣势，中国也就无法建成真正具有国际竞争优势的世界制造业中心。

A NONZERO‐SUM GAME APPROACH TO CONVERTIBLE BONDS: TAX BENEFIT,BANKRUPTCY COST,AND EARLY/LATE CALLS

Convertible bonds are hybrid securities that embody the characteristics of both straight bonds and equities. The conflicts of interest between bondholders and shareholders affect the security prices significantly. In this paper, we investigate how to use a nonzero‐sum game framework to model the interaction between bondholders and shareholders and to evaluate the bond accordingly. Mathematically, this problem can be reduced to a system of variational inequalities and we explicitly derive the Nash equilibrium to the game. Our model shows that credit risk and tax benefit have considerable impacts on the optimal strategies of both parties. The shareholder may issue a call when the debt is in‐the‐money or out‐of‐the‐money. This is consistent with the empirical findings of “late and early calls.” In addition, the optimal call policy under our model offers an explanation for certain stylized patterns related to the returns of company assets and stocks on call.
