Facebook fan page: the effect of perceived socialness in consumer–brand communication

Facebook has become an important platform for a brand–consumer relationship channel. The current study investigates the influence of perceived socialness and its effect on consumers’ attitude toward brands. Participants (N = 404) were recruited in a large southeast university. A 2 (socialness: high vs. low)?×?2 (feedback control: high vs. low)?×?2 (brand image: high vs. low) between-subject design was conducted. The results of this study identified three important findings. First, high (vs. low) socialness elicited higher perceived relationship commitment, brand trust, and more favorable brand attitude. Second, the effect of socialness on brand attitude was moderated by brand image (positive vs. negative). Third, the mediation analysis showed that the effect of socialness (high vs. low) on brand attitude was fully mediated by perceived relationship commitment and brand trust.

Globalizing Business Ethics Research and the Ethical Need to Include the Bottom-of-the-Pyramid Countries: Redefining the Global Triad as Business Systems and Institutions

A majority of the countries in the world are still considered “developing,” with a per capita income of less than U$1,000. Hahn (2008, Journal of Business Ethics 78, 711–721) recently proposed an ambitious business ethics research agenda for integrating the “bottom-of-the-pyramid” countries (Prahalad and Hart, 2002, Strategy and Competition 20, 2–14) through sustainable development and corporate citizenship. Hahn’s work is among the growing field of research in comparative business ethics including the global business ethics index (Michalos, 2008, Journal of Business Ethics 79(1), 9–19; Scholtens and Dam, 2008, Journal of Business Ethics 75(3), 273–284; Tsalikis and Seaton, 2008, Journal of Business Ethics 75(3), 229–238). This article is complementary to Hahn’s work and it advocates an urgent need for business ethics researchers to globally integrate the bottom-of-the-pyramid countries through a fundamental re-definition of the global economic triad, including the United States, Western Europe, and Japan [Ohmae, 1985, Triad Power: The Coming Shape of Global Competition (New York: Free Press)]. The definition that we propose is based on business systems and institutional perspectives that include the bottom-of-the-pyramid countries. We also propose to broaden the research in business ethics to enable comparisons across business systems indifferent income levels.

裂缝性潜山变质岩油藏的合理生产技术对策——以鸭儿峡油田志留系油藏为例

裂缝性潜山变质岩油藏的生产特征复杂,以鸭儿峡油田志留系为例对该类油藏的开发特征进行了分析。结果表明,油藏开发过程中高产井产量递减速度快、累积产油量高、持续时间长,低产井生产状态不稳定,注水初期油井见效明显,油藏含水变化复杂。油井转注、分层酸化压裂、卡水和深抽提液措施实施后油井含水下降,产油量明显上升,显示出良好的开发效果,为后期稳产提供了坚实的技术保障。     

关于人民币汇率弹性增强背景下完善银行资产负债管理的思考

随着我国调节国际收支效果的显现与人民币汇率形成机制市场化程度的不断提高,近年来人民币兑美元即期汇率走势曲折反复,人民币汇率逐渐向均衡水平靠拢,促使企业转变长期以来的汇率预期,着手修复自身资产负债货币错配。这一过程也给商业银行的资产负债货币结构带来显著变化,增加了商业银行本外币流动性管理和资产负债管理难度。对此,商业银行应通过完善自身资产负债管理方式,积极应对这一挑战。
