土地利用图中面状要素缩编的质量评价

研究目的:为保证土地利用图缩编质量,建立土地利用图面状要素缩编的质量评价模型。研究方法:应用模糊综合评判的方法,针对土地利用图中面状要素全覆盖、无重叠、无缝隙等特性,选取曲折度变化率、质心偏移量、土地利用语义、地类面积比例结构以及地图载负量等评价指标,确定各个指标的评价等级和相对权重,建立质量评价模型。研究结果:通过该质量评价模型,比较采用迭代算法和蚁群优化算法缩编的同一个地区,结果显示利用蚁群优化算法进行缩编的效果更好,从而验证了模型的有效性。研究结论:该质量评价模型有助于改进综合算法,改善整个综合过程,保证土地利用图的缩编质量。     

中国企业内部控制评价系统研究

我国企业内部控制基本规范配套指引的发布,为我国企业内部控制体系中构建企业、注册会计师和有关监管部门三位一体的内外部监督评价体系目标的实现奠定了基础。考虑到我国的制度背景以及注册会计师对企业内部控制审计的局限性和可信度等因素,在企业内部控制披露和注册会计师内部控制审计披露的基础上,建立反映企业内部控制综合状况和水平的企业内部控制评价结果指标,由政府监管部门或外部非营利性机构实施对我国企业内部控制整体状况和各企业内部控制水平的评价是十分必要的。本文正是基于此环境和目标,结合国内外企业内部控制评价理论研究和实践状况,构建了我国企业内部控制评价系统。     

‘MODERATION IN ALL THINGS’: INTERNATIONAL COMPARISONS OF GOVERNANCE QUALITY

Comparative measures of aspects of government in different countries are a rapidly growing industry. This paper offers a broad‐ranging critique of the state of the art. The two central questions are (a) How do currently available international measures of governance gain attention from non‐expert audiences, and (b), How understandable are they likely to be to these audiences?’ Findings from a range of relevant literature are brought to bear on three prominent sets of international measures, and conclusions are drawn.     

正确地认识和运用技术指标的背离——基于《证券投资技术分析》教学的思考

技术指标分析是证券投资过程中重要的分析手段之一。但人们对技术指标的背离存在着认识上的偏差和运用上的误区。如何正确地认识和运用技术指标的背离,是教学和实践中必须解决的重要问题。传统经典的技术指标背离忽视了指标本身的周期性规律,以致在运用时经常发出不适宜操作的背离信号,影响股价未来走势研判的准确性。虽然技术指标背离的出现是比较明显的行动信号,但这并不一定要立即采取行动。不宜单独使用背离,还应与其他指标相配合使用。     

论我国房地产市场预警系统的建立

建立房地产市场预警系统有助我们在恰当的时候采用正确的房地产宏观调控措施促进房地产市场健康发展。本文将房价收入比、房价租金比、租金收入比、房地产价格增长率与GDP增长率之比、商品房空置率5个指标作为房地产市场预警统计指标,并对它们的预警区间做出界定,然后根据每个指标的统计数据,确定警兆的警级,结合警兆的重要性进行加权综合,综合成一个指数,这样就可以用一组类似于交通信号灯的标志把当前的房地产市场状态直观地表达出来,用以判断房地产市场过热或衰退的程度,来制定房地产宏观调控的方向。     

论社会保障统计指标体系建立的理论前提

我国目前少量有关社会保障统计指标体系的研究基本集中在对其指标的探讨上,理论支撑明显不足。建立社会保障统计指标体系应首先解决三大理论前提,即社会保障统计指标体系的功能定位、社会保障统计信息需求分析、社会保障统计指标体系的理论依据。这三大理论前提决定着社会保障统计指标体系的目标、方向和基础,对建立社会保障统计指标体系具有重要意义。     

Robustness of Forecasting Financial Crises in Emerging Market Economies with Data Revisions—A Note

Data revisions routinely introduced by the World Bank can lead to significant revisions in empirical results. We show this by re-estimating our aggregate indicator for predicting the 1997 Asian crisis utilizing the 1999 and 2004 updates of the 1996 World Bank data and comparing these results to those we obtained (this Journal, 2000) for predicting the same event using the original, unrevised, 1996 World Bank data. Since most data-gathering organizations routinely revise their data, this may represent a much greater problem for policy makers than might be recognized.     

Publishing performance of Spanish academics: 1970—2004

This work complements some of the results appearing in the article “Publishing Performance in Economics: Spanish Rankings” by Dolado et al. (Span Econ Rev 5: 80–103, 2003) Specifically we focus on the robustness of the results regardless of the time span considered, the effect of the choice of a particular database on the final results, and the effects on changes in the unit of institutional measure (departments vs. institutions as a whole). Differences are significant when we expand the time period considered. There are also significant but small differences if we combine datasets to derive the rankings. Finally, department rankings offer a more precise picture of the situation of the Spanish academics, although results do not differ substantially from those obtained when overall institutions are considered.     

Nutrition and GNP: A comparison of problems in Thailand and the Philippines

The relationship between GNP and nutritional status between countries shows a high correlation. This study of two countries with the same GNP (Thailand and Philippines) investigated their use of equal resources and the impact on nutritional status. Malnutrition is more prevalent in the Philippines than Thailand despite an extensive national nutrition programme in the Philippines, better medical and educational services and safer water supplies. The most important underlying economic factor is not income distribution but rather the cost of living, particularly for basic needs. Finally, it is concluded that although GNP is closely related to nutritional status between countries, the longitudinal correlations within a country are much weaker.
