专题微课生物化学教学新模式的探索与实践

专题微课教学是基于一门学科或课程的某个重要专题设计开发的教学模式。课题组在生物化学的课程中设计了专题微课。生物化学的专题微课教学包括确立教学目标、教学方法、微课录制与编辑加工等环节，应注意建立全新的网络教学平台、互动式教学、抓好指导小组资料整理等教学策略，其成功需要教师有较高的综合素质和教学技能。实践证明，生物化学的专题微课教学取得了良好的教学效果，学生的成绩有了一定提高。     

中国绿色发展中企业环境责任立法探讨

经济活动过程和结果的绿色化主要靠企业承担环境责任来实现，但基于企业的营利本质，期望企业自觉承担环境责任并不现实，必须通过立法从内外部保障、强制其承担环境责任。我国环境保护法及企业法中无法容纳大量的企业环境责任条款，因此我国有必要制定专门的《企业环境责任法》，要求企业承担产品从设计、生产直至废弃的环境责任，并建立环境信息披露、税收优惠等企业承担环境责任的激励约束措施。同时我国应修改环境保护法，提高企业污染环境的成本、将企业环境成本内部化。     

Pesticide‐handling practices: the case of coffee growers in Papua New Guinea

Pesticide mismanagement potentially has high risks for farmers, households living in the community and the environment. In Papua New Guinea where farming is the primary occupation, there is evidence of dangerous herbicide application methods being used by coffee growers. Using original survey data for coffee smallholders from four provinces, we assess the factors driving farmers' use of personal protective equipment when preparing and applying herbicides, and farmers' disposal of agro‐chemical containers. We control for households' demographic variables and measure the impact of farmers' training in pest and disease management. We use the special regressor method to estimate binary choice models featuring an endogenous binary regressor (training). Our results show that human capital (education) and training are important drivers of farmers' pesticide‐handling practices, with marginal effects estimated at 10 and 22 per cent, respectively.     

Bundling attractions for rural tourism development

Tourism is often regarded as a viable solution to economic crisis, especially for remote areas without many development options. While many tourism destinations have strong cultural or heritage assets, not all destinations have primary attractions that can bring visitors to the region. Rather than developing special interest “themes”, rural areas that do not have enough of any one type of tourism resource to act as a primary draw may consider bundling different attraction types to increase visitation. The purpose of this study is to investigate the preferences of visitors to secondary heritage sites and explore the relationship between heritage tourism and alternative, non-heritage activities in rural areas. Findings revealed that motivation to visit small-scale heritage sites consisted of two dimensions: learning and recreation. The two motivational dimensions influenced visitors’ interest in different heritage attractions and likelihood of visiting heritage tourism “scenarios”. As for alternative activities, there was a cluster of “popular” activities that were enjoyed by both learning-oriented and recreation-oriented respondents, but recreation-oriented visitors were more interested in nature-based activities and sport-related activities than learning-oriented visitors. Findings can help rural communities improve secondary attractions and diversify their tourism product by bundling heritage attractions with non-heritage activities.

灰色关联度法在特种设备事故统计分析中的应用

本文以提升安全监察部门和监督检验部门综合分析能力为目的,应用灰色关联度分析方法对历年来特种设备事故的统计资料进行综合分析,以承压类特种设备为例,把特种设备总量、不同种类特种设备总量和不同种类特种设备分别造成的经济损失为指标,分析其与事故造成的直接经济损失总量之间的关联性。增强了对于统计数据综合分析的灵活性,克服了不同量纲数据之间无法寻找规律的不足,从不同角度找到指标之间的关联性,为安全监察部门和监督检验部门分析问题开拓了思路,便于其发现关键指标的主要影响因素,提前预防和集中控制力量。

产品市场竞争与企业投资结构关系的实证分析

本文以中国制造业上市公司为样本,考虑资本市场的典型影响因素与企业内部股权结构,对产品市场竞争与企业内部投资结构的关系进行实证分析。实证结果表明,产品市场竞争与企业广告投入显著正相关;与并购投资之间关系未呈现显著性;而与专用性投资之间呈负相关关系。     

经营性房屋租赁承祖人权益研究——以承租人权益的特殊保护为重心

经营性房屋租凭是房屋租赁的一种特殊类型,与居住性房屋租赁存在诸多区别,而我国有关于房屋租赁的法律主要立足于后者采取一体立法的模式,忽略了经营性房屋租赁的特殊性。一般租赁基本规则难以完全适用于经营性房屋租赁．导致了经营性房屋租赁承租人权益处于保护不利的局面,因此有必要在租赁用途、租赁权续展、租赁权转让方面给予特殊规制。     

国有企业经营者报酬契约模型研究

随着现代企业制度在我国的建立和发展,作为现代公司治理的重要内容和公司长远发展的关键因素,激励约束机制引起了学界的广泛关注。与发达的市场经济下的企业组织相比,由于体制原因和历史遗留问题,国有企业激励约束机制的构建面临着多方面的特殊因素,存在诸多困难。本文主要分析了国有企业委托代理关系的特殊性和复杂性,通过建立国企经营者激励约束的报酬契约模型,为国企激励约束机制的改进提供一个新的思路和方法。
