新冠病毒疫情期间社会治理经验与问题研究——以邢台市任泽区为例

2020年初,一场突如其来的疫情席卷了全中国乃至整个世界,而中国政府反应迅速,上下联动,严防严控,保证了我们国家较低的死亡率和较高的治愈率。论文通过搜集文献、面访、电访等形式,详细了解政府所采取的具体措施和社会机构与政府间的合作,以达到探索并寻找更适合的疫情社会治理措施,对未来突发公共卫生事件提供借鉴意义的目的。     

马鞍山市城乡经济社会发展差距研究

马鞍山市城乡在经济发展、居民收入、生活水平、教育与就业、公共服务等方面都存在着差距,造成城乡经济社会发展差距的原因主要有二元结构、城乡分割体制、政府对农村投入少以及乡镇企业、农村农业合作社发展缓慢等。马鞍山市应以科学发展观为指导,树立正确的发展理念,提出针对性的措施,解决好"三农"发展中存在的问题,促进城乡协调发展。     

How to grow great leaders

Few leaders excel at both the unit and enterprise levels. More than ever, though, corporations need people capable of running business units, functions, or regions and focusing on broader company goals. It's up to organizations to develop leaders who can manage the inherent tensions between unit and enterprise priorities. Take the example of RBC Financial Group, one of the largest, most profitable companies in Canada. In the mid-1990's, RBC revamped its competitive strategy in a couple of ways. After the government announced that the Big Six banks in Canada could neither merge with nor acquire one another, RBC decided to grow through cross-border acquisitions. Additionally, because customers were starting to seek bundled products and services, RBC reached across its traditional stand-alone businesses to offer integrated solutions. These changes in strategy didn't elicit immediate companywide support. Instinctively, employees reacted against what would amount to a delicate balancing act: They would have to lift their focus out of their silos while continuing to meet unit goals. However, by communicating extensively with staff members, cross-fertilizing talent across unit boundaries, and targeting rewards to shape performance, RBC was able to cultivate rising leaders with the unit expertise and the enterprise vision to help the company fulfill its new aims. Growing such well-rounded leaders takes sustained effort because unit-enterprise tensions are quite real. Three common conditions reinforce these tensions. First, most organizational structures foster silo thinking and unimaginative career paths. Second, most companies lack venues for airing and resolving conflicts that arise when there are competing priorities. Third, many have misguided reward systems that pit unit performance against enterprise considerations. Such long-established patterns of organizational behavior are tough to break. Fortunately, as RBC discovered, people can be trained to think and work differently.     

Construct Validity of Dichotomous and Polychotomous Choice Contingent Valuation Questions

In this note we conduct construct validity tests for dichotomous choice (DC) and polychotomous choice (PC) contingent valuation questions. Contrary to previous results, we find that DC and PC estimates of willingness to pay are theoretically valid, convergent valid, and similar in terms of statistical precision. Similar to previous results, PC respondents are less sensitive to information than DC respondents. We conclude that DC and PC valuation questions are construct valid for this study. Sequential PC valuation questions could be used in studies where obtaining information about the certainty or intensity of respondent preferences would be useful.     

An economic analysis of wind erosion control in the inner Mongolia Plateau,China

This study investigates specific changes in farming practices aimed at reducing wind erosion from cropland in the inner Mongolia Plateau, China, and incorporates the value of dust reduction in downwind regions into a formal cost-benefit framework, both from the farmer's perspective and society's perspective. The result shows the need for incorporating off-site damages from wind erosion in policy analyses. Measurement of the off-site damages is difficult, especially in a mixed economy such as China's. A conservative estimate was obtained by benefit transfer from a non-market valuation study conducted in a developed country. This conservative estimate was large enough to be decisive in the policy analysis.     

Estimating the profits from trading strategies

Price improvement is the difference between the execution priceof an order and the quoted bid or ask when the order was submitted.We show that expected price improvement falls off dramaticallyas the size of the order approaches the quoted depth, and becomesnegative for larger orders. This is particularly important forsmall firms because the quoted depths are low. Using quotedspreads and depths and our estimate of expected price improvement,we show that trading strategies that attempt to exploit theweekly predictability of small-firm returns would be swampedby transaction costs.     

集团企业授信风险防范问题研究

近来随着一系列大型企业集团如蓝田、银广夏、德隆、啤酒花、南海华光、上海周正毅关联企业、深圳彭海怀兄弟企业、江苏铁本公司等企业相继出事,商业银行对集团企业授信风险问题变得日益突出。采取措施加强对集团客户授信业务的监督和管理,有效防范和控制集团客户授信风险,不仅是保证银行信贷资产安全,实现银行稳健经营和可持续发展的需要,也是维护国家金融安全,构建和谐社会的需要,不可小视。     

The probability and magnitude of information events

Models of adverse selection risk generally assume that market makers offset expected losses to informed traders with expected gains from the uninformed. We recognize that the expected loss captures a combination of two effects: (1) the probability that some traders have private information, and (2) the likely magnitude of that information. We use a maximum-likelihood approach to separately estimate the probability and magnitude of private information events for NYSE-listed stocks from 1993 through 2003. The results shed light on the price discovery process and have implications for many areas of finance.     

改进的宽带信号有理数倍采样率变换结构

针对现有的数字器件无法满足对宽带信号进行有理数倍采样率变换的问题,提出了 一种改进的宽带信号有理数倍采样率转换结构。在分析抽取器与内插器顺序的基础上,得出 了等效变换的前提条件,并结合多相滤波结构使改进的结构更具有实际应用价值。仿真实验 证明了改进后结构的有效性。通过与现有有理数倍采样率变换结构运算量对比分析表明,改 进后的结构的运算效率为传统结构运算效率的1/（LM）倍,其中L和M为变换过程中的内插因 子和抽取因子。     

企业技术能力与外资对华技术转移的关联研究

将企业技术能力细化为识别技术、选择技术、获取技术、利用技术和保护技术等五个具体能力和一个核心的技术库，五个能力会对外资对华技术转移产生正面和负面影响。外资对中国企业技术能力的提升主要体现在获取技术环节，外资对核心知识的封锁是市场竞争的必然选择，对于技术库的知识累积，只能依靠企业自身的努力。
