Visual Basic对象通信的实现与应用

针对面向对象系统中对象的交互分为调入界面和调出界面,阐述了VB调出界面的2种通信机制,即事件和回调,并对二者进行了详细比较,分析了它们的特点和适用对象,进而通过在基于异步调用的网络监控系统中的应用实例,体现了基于回调机制的对象通信技术对于设计和开发复杂的面向对象系统的重要意义。     

论证券投资基金的收益及其分配

证券投资基金的收益主要包括利息收入，股利收入和资本利得。在甸证券市场发育不完善的现阶段，出于会计谨慎性原则的考虑，证券投资基金的收益不应包括股票股利和未实现的资本利得。在收益分配方面，管理层对证券投资基金收益分配政策的限制过程多过死，不利于投资基金业的健康发展，基金持有人大会在基金收益分配政策的制定上应当享有更多的决定权。     

探析社会保障基金的财务可持续性

社会保障基金在财务方面的可持续性是社会保障制度的物质基础和重要前提,因此必须把社会保障基金的可持续性作为首要的原则。社会保障基金必须保证短期内的收支平衡,长期内的保值增值,最终实现社会保障制度的可持续发展。     

Social Security and personal saving: 1971 and beyond

Feldstein (1996, 1974) reported that Social Security in the U.S.A. reduced personal saving (“saving”) in 1992 (1971) by $416 ($61) billion. I reestimate his life-cycle consumption specification using data from the latest NIPA revision, correct his calculations, and find that the implied reduction in 1992 (1971) saving is now $280 ($22) billion, 48% (16%) of actual net private saving, with a standard error of $114 ($14) billion. If structural breaks around WWII and the 1972 Social Security amendments (which raised real per capita SSW by 22%) are allowed, and the market value of Treasury debt included in the specification, the reduction in 1971 and 1992 saving attributable to Social Security is at most 0.55 times its standard error, and 12% of net private saving. I then reestimate the preferred specification of Coates and Humphreys (1999), allowing for these structural breaks and relaxing other restrictions. The implied effect of Social Security on saving is again statistically zero.

劳动者视角:企业职业安全保障供给不足之机理分析

当前我国职业伤害事故正处于高发的态势,职业安全保障已成为国内学界关注的热点。基于劳动者视角,将职业安全保障看作特殊商品由企业供给,需求方为劳动者,剖析了当前我国企业在职业安全保障方面供给不足的机理,并给出了相应的改进措施。     

Linking forestry, sustainability and aesthetics

In forest planning, little research has been devoted towards examining how visual-impact assessment can improve the public acceptance of forest activities and augment forest sustainability. The objective of the present work is to review the methods of aesthetic assessment of forest landscapes, which will help the implementation of visual-impact assessment in sustainable forestry. From the numerous techniques of landscape evaluation that have been devised in recent years, the expert approach techniques have dominated in environmental management practices and the perception-based approach in research. The non-market economic valuation techniques are essentially trade-off methods and not aesthetic assessments by themselves. Revealed preference methods, such as hedonic-price, use actual market choices of individuals to get their preferences towards non-market attributes, and stated preference methods, such as contingent valuation method, rely on surveys to get directly the individual's willingness to pay for the non-market attributes. Psychophysical preference modelling is a popular quantitative holistic technique of landscape evaluation and if used in combination with indirect aesthetic evaluation methods might create new standards and protocols for techniques of objectively estimating public perception of aesthetic quality and thus to enhance social sustainability in forest space.     

完善住房保障体系努力实现住有所居

住房问题是民生问题、社会问题,也是经济问题、政治问题.进一步扩大保障性住房建设规模尤为重要.2004年以来,赣州抓好建设、分配、管理环节,构建了以廉租住房实物配租为主,经济适用房、棚户区(危旧房)改造、公共租赁房和廉租店铺等多种形式为补充的具有赣州特色的住房保障体系,较好地解决了中低收入居民住房困难问题.
