高油价时代保障国家石油安全之策

1999年以来,国际油价增长了近7倍,屡次突破历史高点.前不久,已连续数月在每桶75美元左右徘徊.由此可见,世界正迈入一个高油价时代.作为世界石油第二大消费国,高油价已对我国石油安全构成一定的影响.我国经济建设的焦点之一在能源,而能源安全的核心在石油.保障石油安全是实施国家能源安全战略最重要的一环,须予以高度重视,并采取切实可行的对策.     

基于通道经济下的广西中心城市经济走廊构建反思

近年来广西建成的西南出海大通道,使大西南腹地和北部湾港口通过铁路、公路和航空网络形成了一个体系,但其体系功能并未充分发挥;充分利用广西独特的区位优势,资源优势及政策优势,加快广西中心城市经济走廊和通道经济建设,加强与东、西部地区的经济合作,实现"西江经济走廊"和粤桂一体化,全面融入殊三角,是广西构建中心城市经济走廊和通道经济建设和实现以"富裕广西、文化广西、生态广西、平安广西"为目标的"四个广西"和谐社会的必然选择.     

Assessing the Effects of Cultural Intelligence on Team Knowledge Sharing From a Socio‐Cognitive Perspective

Drawing upon social cognitive theory, this research postulates cultural intelligence as a key driver of knowledge sharing among culturally diverse teams. An empirical testing of the proposed model, by investigating team leaders from high‐tech industries, reveals the applicability of social cognitive theory in understanding cultural intelligence, perceived team efficacy, and knowledge sharing. Specifically, the test results herein show that knowledge sharing is directly influenced by metacognitive, cognitive, and motivational cultural intelligence. At the same time, knowledge sharing is indirectly impacted by metacognitive and behavioral cultural intelligence through the mediation of perceived team efficacy. Lastly, this research provides managerial implications and limitations. © 2013 Wiley Periodicals, Inc.     

On the maxima of heterogeneous gamma variables with different shape and scale parameters

In this article, we study the stochastic properties of the maxima from two independent heterogeneous gamma random variables with different both shape parameters and scale parameters. Our main purpose is to address how the heterogeneity of a random sample of size 2 affects the magnitude, skewness and dispersion of the maxima in the sense of various stochastic orderings. Let \(X_{1}\) and \(X_{2}\) be two independent gamma random variables with \(X_{i}\) having shape parameter \(r_{i}>0\) and scale parameter \(\lambda _{i}\) , \(i=1,2\) , and let \(X^{*}_{1}\) and \(X^{*}_{2}\) be another set of independent gamma random variables with \(X^{*}_{i}\) having shape parameter \(r_{i}^{*}>0\) and scale parameter \(\lambda _{i}^{*}\) , \(i=1,2\) . Denote by \(X_{2:2}\) and \(X^{*}_{2:2}\) the corresponding maxima, respectively. It is proved that, among others, if \((r_{1},r_{2})\) majorize \((r_{1}^{*},r_{2}^{*})\) and \((\lambda _{1},\lambda _{2})\) weakly majorize \((\lambda _{1}^{*},\lambda _{2}^{*})\) , then \(X_{2:2}\) is stochastically larger that \(X^{*}_{2:2}\) in the sense of the likelihood ratio order. We also study the skewness according to the star order for which a very general sufficient condition is provided, using which some useful consequences can be obtained. The new results established here strengthen and generalize some of the results known in the literature.
