基于基尼系数对我国城乡收入差距的预警分析

城乡收入差距过大日渐成为一个被社会关注的热点。在划定我国城乡居民收入分配差距国内“警戒线”的基础上构建了我国城乡收入分配差异的预警体系,并对未来十年我国城乡居民收入分配状况进行了预警分析。结果表明：2011年我国城乡差距将达到新高。     

石油企业生产型员工人力资源法律风险预警模型研究——以M公司为例

针对石油企业生产型员工这一特殊群体,建立了人力资源法律风险预警模型。采用德尔菲法完成指标筛选确定指标预警区间,通过层次分析法计算指标权重,运用模糊数学综合评价法计算风险等级。并以我国M公司境外石油勘探项目为例对风险预警模型进行验证。管理者依据模型可以测试该类员工现场管理的法律风险,发出预警信号。     

基于DAF的煤矿风险预警模型研究及应用

为降低煤矿事故率,改变传统煤矿风险预警模式,使用DAF(德尔菲法、层次分析法、模糊综合评价法)对煤矿安全生产状态进行评价。通过德尔菲法调查分析影响煤矿安全生产的指标因素,选取其中关键性的34项指标来构建预警指标体系,利用层次分析法计算各指标权重,结合模糊数学理论,运用模糊综合评价法进行综合评价,判断出煤矿的安全状态,建立煤矿风险预警模型,并结合实际案例验证其可行性。结果表明,通过模型的数值计算,可以直观判断煤矿的安全生产状态,达到提前预测预警,减少煤矿生产事故发生的目的。     

J2EE企业级应用开发技术发展趋势

J2EE企业级开发技术的发展可以反映为MVC框架的变迁。Struts依靠其前期的成功,目前仍旧占有大量的用户市场,Struts2.0的推出,进一步巩固Struts的应用地位。Hibernate框架实现了高效的数据持久化,极大提高了数据库层逻辑的开发效率,并且可以与Struts相融合。Spring技术作为轻型框架,依靠IoC在J2EE应用中占有重要地位,随着新技术的补充和完善,Spring技术的未来值得期待。     

用标准样地进行耕地质量动态监测与预警探讨

研究目的:农用地分等成果中的标准样地能代表其所在小区域耕地质量特征,对设定范围内一定数量的标准样地进行监测,结合农用地分等结果,可以掌握该范围内耕地质量的变化情况,基于此探索建立耕地质量动态监测与预警体系。研究方法:用标准样地结合遥感、GIS等手段构建体系。研究结果:给出基于标准样地的耕地质量动态监测与预警体系初步框架。研究结论:耕地质量动态监测与预警的实现是国土资源由数量管理向数量、质量并重管理的重要技术基础。     

Importance of early snowfall for Swedish ski resorts: Evidence based on monthly data

Since the early 1970s, Sweden has experienced an almost uninterrupted surge in demand for downhill skiing. However, from the 2009/2010 season, lift ticket sales have stagnated. With the use of monthly data, this study investigates the role of snow depth and economic factors in the demand for downhill skiing in Sweden. The empirical approach is based on a seemingly unrelated regression model, allowing snow conditions, but not economic factors to differ during the season. The estimates show that an early season increase in natural snow depth by 10 cm raises the growth rate of lift ticket sales by 9 percentage points in the same period. Further, the results indicate that downhill skiing is characterised by low income and price elasticities, implying weak impacts on demand for such changes. The price increase of lift tickets exceeds that of the inflation rate. The recent decline in demand might indicate changed leisure preferences.     

Human resource management and early internationalization: is there a leap-frogging in international staffing?

The present study focuses on the international staffing of early internationalizers by linking the Ethnocentric, Polycentric, Regiocentric, and Geocentric (EPRG) concept with the Process Theories of Internationalization. On a dataset of 116 (N) German medium-sized companies, we test whether the determinants which allow firms to internationalize shortly after their inception, namely prior international experience, technological intensity, and networks, influence the firms' international staffing. We further elaborate whether this influence differs between early and late internationalizers. The empirical results show that prior international experience is not associated with the firms' international staffing at all, and thus, does not allow conclusions. Technological intensity increases the probability of the choice of an ethnocentric staffing policy, especially for early internationalizers. In contrast, networks enable firms, especially early internationalizers, to pursue regiocentric or geocentric staffing policies.     

Commerce and Colonisation: Studies of Early Modern Merchant Capitalism in the Atlantic Economy

ABSTRACT

Postage accounts kept by merchants active in North and Baltic Sea trade are used to track the development of transmitting costs of remote information. As a long-run aggregated trend in terms of the real price, the postage stayed approximately at the same level until 1770s and decreased substantially thereafter. War factor proved to have had a variable influence. Increased demand on information exchange, driven by booming trade in this period, arguably promoted lower-cost transmission. The present paper also reveals that, over time, international postage was increasingly a function of geographical distance and, due to the changes in means of transmission and also due to the specific tariff policy of national Posts, there was significant cost–space convergence regarding domestic transmission while the same trend was much less dominant at an international level.     

西学东渐与清末民初安徽传统社会观念风气变化

社会观念、社会风气的转变是社会变迁的一个重要方面。清末民初安徽传统的“重义理，轻艺事”观念、“重农轻商”“重儒轻商”观念的动摇，男女平等观念开始出现端倪，旧的生活方式和政治生活方式的些许变化及读新书、阅报刊、学外语、出国留学等新风气的出现，表明清末民初安徽传统的社会观念、社会风气在一定程度上、一定范围内有了异于传统的变化。这些变化，既是外力冲击的结果，也是安徽自身为适应时代的变化而不断自我调整的结果。但这些变化主要是发生在城市、城镇及社会上层，广大农村及社会下层的观念、风气还是较为保守的，对安徽社会来说，要使变化从点发展到面，从上延伸到下，还需要一段路程要走。     

不让中州独专美——《钟情丽集》与明前期海南历史文化

文言中篇小说《钟情丽集》问世于明前期海南文教事业取得跳跃式大发展的背景之下,具有鲜明的地域特色和时代特征。它的问世填补了海南在古典小说领域的空白。作者"不让中州独专美"的创作心态赋予《钟情丽集》特殊的文化意义。只有将《钟情丽集》与明前期海南历史文化相结合,才能对其思想、艺术特点作出更加深入合理的解读。
