Social capital approach on Enterprise 2.0: a multiple case study

The goal of Enterprise 2.0 is to create a collaborative work environment and facilitate knowledge sharing. However, organisations report both increases and decreases in productivity associated with Enterprise 2.0. The focal qualitative case study adopts the social capital approach as a theoretical lens to provide a holistic account of Enterprise 2.0. The study reveals the multilevel and multifaceted nature of Enterprise 2.0 and shows how it associates with individual employees’ behaviours, their mutual work- and non-work-related relationships and knowledge sharing patterns, as well as managerial processes. Thus, the study continues and contributes by going beyond the mere operational use and benefits of Enterprise 2.0, and approaches it as a holistic socio-technical phenomenon that largely intertwines with organisational realities and strategic management. Furthermore, the study provides a discussion on Enterprise 2.0 as a driver of social change, and what kind of managerial action and involvement is required for its success.     

Determinants of housing price volatility in Canada: a dynamic analysis

This article tries to identify the determinants of housing price volatility and to examine the dynamic effects of these determinants on volatility using quarterly data for Canada. The Generalized Autoregressive Conditional Heteroskedastic (GARCH) and the Vector Autoregressive (VAR) models have been employed to analyse possible time variation of the housing price volatility and the interactions between the volatility and the key macroeconomic variables. We find the evidence of time varying housing price volatility for Canada. Our VAR, Granger causality and variance decomposition (VDC) analyses demonstrate that housing price volatility is affected significantly by gross domestic product (GDP) growth rate, housing price appreciation rate and inflation. On the other hand, volatility affects GDP growth rate, housing price appreciation and volatility itself. The impulse response analysis reveals the asymmetric of the positive and negative shocks. The findings of this article have important implications, particularly for those seeking to develop derivatives for housing market prices.     

Media freedom and gender equality: a cross-national instrumental variable quantile analysis

We investigate the impact of media freedom on gender equality in education for a sample of 63 countries taken over the period 1995–2004. Our analysis is motivated by the idea that the impact of media freedom on gender equality may differ over the conditional distribution of the response variable. Using instrumental variable quantile regression to control for endogeneity in per capita income, we find that greater freedom of the media improves gender equality only in the 0.25 and 0.50 quantiles of the conditional distribution. Countries with the greatest disparities in gender outcomes experience no significant impact of media freedom.     

Do analysts follow emerging economy firms with higher intangible assets? Empirical evidence from Egypt

This paper tests whether analyst coverage and effort are related to the level of intangible assets reported by Egyptian listed firms. Intangible assets represent increasingly important investments for many firms, but most of these assets are not capitalized under prevailing accounting standards. Analysts reduce the information asymmetry by examining both financial reports and other information. Many Egyptian firms today seek access to foreign capital. I hypothesize that the larger the potential intangible assets of firms the more analysts will cover these firms and pursue private information about these firms. Sample consists of 435 firm-year observations over the period 1999–2007, and intangible assets are measured using eight different firm- and industry-level proxies. Consistent with prior research, results suggest that coverage is significantly associated with firm R&D, industry advertising expenses, firm size, and trading volume. Results also suggest that analyst effort is a function of firm and industry-level R&D expenses and firm size.     

董事会本地化与企业创新——兼论权力及文化的影响

聚焦董事会本地化的“度”,从个体和群体角度分析本地董事对企业创新的作用机理,通过匹配2007—2019年我国A股上市公司注册地与董事会成员籍贯地数据,实证检验董事会本地化对企业创新的影响以及在不同权力、文化情境下的异质性。研究结果表明：董事会本地化与企业创新之间呈倒“U”型关系,适度本地化能够促进企业创新,但过度本地化会损害企业创新,而且这种倒“U”型关系在董事长是本地人、地区信任文化氛围浓厚的情况下更加显著。进一步的中介机制检验发现,董事会本地化通过影响企业风险承担水平和董事会人力资本质量进而作用于企业创新。此外,良好的媒体监督和法律环境有助于抑制董事会本地化对企业创新的负面影响。研究结论从董事会成员地缘属性视角丰富了企业创新影响因素的文献,揭示了董事会本地化对企业创新的“双刃剑”效应,对推动企业创新具有较强的指导意义。

警察的媒介形象构建分析

本文运用内容分析法,研究了由05年1月1日至09年12月31日在《南方周末》以及与之相关的南方报业网中以"警察"为标题的345个文本资料并进行分析研究。发现并了解此类评论性媒介倾向于选择警察负面新闻进行报道,造成负面报道比重过高,丑化警察媒介形象。嫌介对警察负面形象的持续报道,有意或无意识的造成了负面新闻在时空上产生共鸣效果、累积效果,进一步加剧了警察媒介形象丑化。进而影响着公安机关在人民群众心目中的形象,甚至于影响着整个政府的公信力。
