黑龙江省煤炭城市土地利用综合效益时空变异分析

定量分析和评价煤炭城市土地利用综合效益并确定其空间分布,为煤炭城市集约合理利用土地提供科学依据。以黑龙江省煤炭城市为例,以影响城市土地利用综合效益的土地投入效益、土地利用效益、土地产出效益和土地生态效益为要素层,构建黑龙江省煤炭城市土地利用综合效益评价指标体系,运用最优组合赋权法确定指标权重,采取多目标综合评价法,对2002—2007年土地利用综合效益进行定量分析。结果表明,黑龙江省煤炭城市6年间土地利用综合效益呈上升趋势。土地投入效益、土地利用效益、土地产出效益和土地生态效益对土地利用综合效益影响存在一定的差异,土地利用协调度呈现先上升后下降的趋势,土地利用协调度的下降将成为土地利用综合效益进一步增长的障碍。     

Is it the economic policy,stupid? Economic policy,political parties & the gubernatorial incumbent advantage

Incumbent politicians have a well-known advantage in seeking re-election. Using the Economic Freedom of North America dataset, we examine how changes in economic policy during an incumbent governor's tenure influence the probability of losing their re-election bid. Put simply, does economic policy matter for the incumbent advantage? The results suggest that a decrease in economic freedom increases the probability of an incumbent loss, regardless of the governor's party. A decomposition analysis indicates that these results are primarily driven by the government spending sub-index. Furthermore, a more granular analysis suggests that: (1) increases in government consumption spending and government employment are associated with a lower probability of re-election among Democratic incumbent governors, but a higher probability among Republicans; (2) increases in transfer payments relative to personal income reduce the likelihood of re-election, regardless of party; and (3) among Republican incumbents, increases of income taxation and of top marginal tax rates are associated with a higher and lower, respectively, probability of losing re-election. Finally, controlling for a variety of demographic, political and socioeconomic factors, we find that high unemployment increases the probability that an incumbent loses re-election, while increasing net population migration reduces it.     

我国公共财政制度的完善

消费与投资增长不协调是我国当前宏观经济中的重要问题,这个问题已成为我国经济社会协调发展的严重障碍,公共财政制度不完善是这一问题产生的财政体制根源。所以, 加快公共财政体制建设就成了解决这一问题的根本途径。就我国当前来说,公共财政应该加大对义务教育、公共卫生、社会保障、"三农"问题、收入分配和就业问题的支持力度和调控力度。     

中外高校机构编制管理的比较及启示

我国高校机构编制管理缺乏有力的外部监督和内部约束;而以美国为代表的国外高校则在“行政-学术”二元权力架构的安排、管理机构的设置、人员编制的分类与控制等方面形成了一整套科学的做法。借鉴其经验,应通过国家或地方行政立法来规范高校机构编制管理,将机构编制管理绩效纳入对高校的考核范围,要在精简机构的同时建立健全高校的学术权力机构,各地教育行政部门也要建立起一套完善的实施监管的技术性程序。     

高职数学与文化课程教学设计与实施研究

长期以来,高职数学教学过分注重数学知识的学习及技能的训练,追求数学结果的推理演绎,忽视了与数学结果相关的人文因素,影响了对学生的数学文化教育。数学文化作为现代人文化素质的一部分,不仅是概念、定理、公式、计算,更是一种思维方式、创新品质、文化精神。它在陶冶人的情操、健全自我人格、提高思维能力、传播文化思想、实现人的全面发展等方面具有不可忽视的作用。通过对高职院校开设数学与文化课程的研究与实践,积极探索高职数学课程改革方案,深化了高职数学的课程改革,创新了高职数学的教育理念。     

对旅游饭店星级评定中安全与应急预案规定标准的分析

《旅游饭店星级的划分与评定》（GB/T14308-2010）于2011年1月1日起开始实施。这部标准在旅游饭店安全与应急预案的规定比历次标准更加细化与明确,形成了比较完备的促进旅游饭店业整体发展的星级评定管理体系。它不仅提出有限服务饭店与完全服务饭店的概念,还特别强调安全与应急管理,这是该标准的最大亮点,体现和谐社会中＂人性化＂的要求,为此,它要求培育企业安全文化,使旅游饭店在运营中明确安全理念、安全制度、应急预案的重要地位和对宾客的重要性。但在安全与应急预案中的相关规定中还存有一些值得探讨和分析的问题。通过对《旅游饭店星级的划分与评定》（GB/T14308-2010）的思考和细致分析,指出其中需修补完善的地方,认为星评标准是动态的,在实践和应用中要不断的根据客观情况加以调整。因此,根据旅游管理理论和实践两方面的要求,提出进一步完善的建议。     

趋同的城乡生育意愿对生育政策调整的启示--基于北京市城乡独生子女生育意愿的比较研究

对北京市2006年和2008年的城乡独生子女生育意愿作了调查。在我国经济社会较为发达地区,城乡独生子女的生育意愿无论在生育数量还是在子女性别偏好和生育时间上都存在趋同的现象。对目前各省市在生育政策调整时城市和农村依然采取不同政策的做法提出看法。在经济社会较为发达的省市,可以推行城乡一体化的生育政策。     

EDGAR on the internet: The welfare effects of wider information distribution in an experimental market for risky assets

Policies such as the SEC’s Fair Disclosure Rule, and technologies such as SEC EDGAR, aim to disseminate corporate disclosures to a wider audience of investors in risky assets. In this study, we adopt an experimental approach to measure whether this wider disclosure is beneficial to these investors. Price-clearing equilibrium models based on utility maximization and non-revealing and fully-revealing prices predict that in a pure exchange economy, an arbitrary trader would prefer that no investors are informed rather than all are informed; non-revealing theory further predicts that an arbitrary trader would prefer a situation in which all traders are informed rather than half the traders are informed. These predictions can be summarized as “None > All > Half”. A laboratory study was conducted to test these predictions. Where previous studies have largely focused on information dissemination and its effects on equilibrium price and insider profits, we focus instead on traders’ expected utility, as measured by their preferences for markets in which none, half, or all traders are informed. Our experimental result contradicts the prediction and indicates “Half > None > All”, i.e. subjects favor a situation where a random half is informed. The implication is that in addition to testing predictions of price equilibrium, experiments should also be used to verify analytical welfare predictions of expected utility under different policy choices.

Are imports and remittances cointegrated for the Central and Eastern European countries?

In this article, we investigate the existence of long-run common trends between imports and remittances in 11 Central and Eastern European countries which are part of the European Union. Using the Engle–Granger two-step procedure, we determine that for all countries in our sample there are no long-run common trends (no cointegration) between imports and remittances. However, the results are mixed when running a Granger causality test. For nine countries, we can establish either a bidirectional or unidirectional Granger causality, indicating that past values of one variable have predictive content on the other variable. In two countries, there is no Granger causality between imports and remittances.
