从旅游资源角度看西藏旅游区域联合开发的可行性

采取合理的开发方式对旅游资源进行整合开发可以推动旅游业的发展,旅游区域联合开发是当今旅游资源开发的必然趋势。西藏拥有世界上独一无二的旅游资源,但却面临诸多旅游开发的难题。文章从旅游资源的视角出发,对西藏自然、人文旅游资源进行分析后得出：西藏各地区旅游资源既具有高度关联性,又相互区别、各具特色,为旅游区域联合开发提供了必要的资源条件。     

论"十二五"时期文化产业的发展路径

在实现"十一五"目标、谋划"十二五"发展的关键之年,中国文化产业的发展需要从更加理性务实的决策思路出发,在较高的起点上为实现经济发展方式转变进行深入的思考.应把握七条原则:注重实际操作,制定科学规划;加大整合力量,提高创新投入;优化管理创新,加强组织协调;规范统计口径,制定行业标准;丰富文化消费,创新产品服务;推进城乡统筹,形成特色布局;优化人才机制,实施量化考核.     

正义视阈中的高校“思政”课教育

高校＂思想政治理论＂课是大学生思想道德建设,树立共产主义理想和正确的世界观、人生观、价值观的主渠道。从正义理论出发,通过公正公开的教育理念和内在德性的塑造,通过公民权利意识的提升与和谐有序正义的建构,可以为提高＂思政＂课教育的实效性和时效性提供一种参考性的认知方式。     

带有潜变量的结构方程模型在突发事件应急管理中的应用

如何使事件与机构挂钩是突发事件应急管理中的一个重要问题;通过带有潜变量的结构方程模型能够建立起事件与机构之间的定量联系,从而为进一步对机构作评价和制定考核标准提供依据。     

An optimal online algorithm for the parallel-batch scheduling with job processing time compatibilities

We consider the online (over time) scheduling on a single unbounded parallel-batch machine with job processing time compatibilities to minimize makespan. In the problem, a constant \(\alpha >0\) is given in advance. Each job \(J_{j}\) has a normal processing time \(p_j\). Two jobs \(J_i\) and \(J_j\) are compatible if \(\max \{p_i, p_j\} \le (1+\alpha )\cdot \min \{p_i, p_j\}\). In the problem, mutually compatible jobs can form a batch being processed on the machine. The processing time of a batch is equal to the maximum normal processing time of the jobs in this batch. For this problem, we provide an optimal online algorithm with a competitive ratio of \(1+\beta _\alpha \), where \(\beta _\alpha \) is the positive root of the equation \((1+\alpha )x^{2}+\alpha x=1+\alpha \).     

China’s GDP: Examining provincial disparities (1952–1998)

Accompanying rapid economic growth in China, there have been provincial disparities. This article presents and analyzes the evolution of Chinas provincial GDP per capita disparity between 1952 and 1998. First, an examination of some basic indicators of disparity is carried out, and a test for unconditional convergence is performed to explore the dispersion features. Then, a more comprehensive regression analysis, allowing insights into the evidence of conditional convergence and highlighting the main determinants of growth in two main periods of the recent history of China (i.e., prereform and postreform) is presented. Finally, a discussion and conclusion are provided.     

基于进化博弈的专利联盟形成研究

专利联盟作为高新技术产业发展的主导范式,对技术标准的建立有重要的作用。但是多数情况下提高社会福利的联盟却难以形成,这就是所谓专利联盟的形成困境问题。从专利权人的有限理性和重复博弈角度分析专利联盟的形成,分别建立对称和非对称专利联盟形成的进化博弈模型,得到不同条件下的进化稳定策略,并探讨影响联盟形成的条件和因素。研究结果表明,专利联盟更容易在弹性高、竞争激烈的市场环境中形成;与事实标准建立以后相比,在事前组建的专利联盟形成可能性更大;通过多方途径保护和提高加入联盟的专利权人的利润,同时抑制阻碍联盟的专利权人的利润,是促进联盟形成的关键;与专业R&D企业相比,纵向一体化企业有更强的动机加入联盟。健全和完善相关法规及配套服务对联盟形成也是有益的。     

Validation of the Learning Transfer System Inventory (LTSI) in the Korean corporate context

Lack of a valid instrument to measure learning transfer predictors has been the major obstacle hindering Human Resource Development (HRD) professionals from moving forward. This problem is one of the lingering HRD issues in South Korea, in which human resources have been strategically emphasized as a critical asset due to the scarcity of natural resources. To address this issue, this study aims at testing the validity and reliability of the data collected with the Korean Learning Transfer System Inventory (LTSI) Version 4. A sample of 753 managers from 16 Korean industries was divided into two subsamples for exploratory and confirmatory factor analyses. Reliability and the effect of common method variance on the factor structure were examined, with the results suggesting that the LTSI is valid for use in the Korean industry.     

Marketing as an Investment in Shareholder Value

We present resource‐based and capability‐based arguments of marketing investment intensity to offer a strategic view of marketing as an investment in shareholder value. We find that marketing investment intensity has a U‐shaped quadratic effect on shareholder value creation (Tobin's q) that calls for marketing investment to be protected and increased, not surrendered. We show how marketing investments interact with investments in R&D, human capital and operations to reveal how strategic co‐investments can alter the shareholder value of marketing. Finally, we show how competitive intensity and failings in the firm's investment productivity (its ability to convert investment expenditure into sales) point to malaise in the firm's own strategic architecture as a fault for perceived poor returns from marketing investments. Our findings suggest that marketing investment should not be scapegoated when its contributions to shareholder value are not as expected. When invested in strategically and in combination with other investments, marketing can unlock exciting improvements in shareholder value.     

人民币汇率的双成分混合波动率模型

汇率波动性预测在金融和计算领域一直受到广泛关注,然而由于缺乏可以捕捉汇率波动动态变化的预测模型,高频汇率的波动率预测至今没有得到彻底的研究.文章提出了基于神经网络的双成分混合汇率波动率模型,该模型利用低通Hodrick-Prescott滤波器将已实现波动率分解为长期分量和短期分量,使用自回归神经网络模拟长期分量,一阶自回归过程模拟短期分量,通过实证分析确定自回归神经网络参数(10个隐神经元和四阶滞后输入神经元),以6种主要高频率汇率(英镑/人民币,美元/人民币,澳元/人民币,欧元/人民币,日元/人民币,和瑞士法郎/人民币),在5 h(d)、20 h(d)、100 h(d)、200 h(d)、360 h(d)和500 h(d)的预测区间构建1 h和1 d已实现波动率,并与双成分GARCH模型、EGARCH模型、四阶滞后自回归神经网络模型3个基准模型进行对比,分析模型的预测性能,实验评估表明,提出的混合预测模型在所有预测的范围内均显著地优于传统人民币汇率波动模型.
