如何解决传媒人才短缺难题

当前,传媒业的激烈竞争实质上是人才的竞争。人才是传媒成败的“牛耳”。解决人才短缺问题是着眼向外,还是着手向内？不排除向外,但主要应下力激活内部人力资源。这样做,可以防止造成新的人才浪费,可以避免爆发恶性人才大战,从而有利于传媒业的和谐发展。那种过份“引进”、忽视“挖潜”的做法是不可取的。     

Market reactions to the disclosure of internal control weaknesses and to the characteristics of those weaknesses under section 302 of the Sarbanes Oxley Act of 2002

We examine the stock price reaction to management’s disclosure of internal control weaknesses under §302 of the Sarbanes Oxley Act and to the characteristics of these weaknesses, controlling for other material announcements in the event window. We find that some characteristics of the weaknesses—their severity, management’s conclusion regarding the effectiveness of the controls, their auditability, and the vagueness of the disclosures—are informative. We also find that the information content of internal control weakness disclosures depends on the severity of the internal control weakness. Moreover, in a sub-sample uncontaminated by other announcements in the event window, we find negative price reactions to the disclosure of internal control weaknesses and material weaknesses.

内外均衡冲突下的人民币汇率政策选择:基于斯旺模型的研究

本文以斯旺模型为理论基础,研究了当前中国经济内外均衡,中突,并对内外均衡冲突下的汇率政策和货币政策之间的冲突进行了深入分析。根据斯旺模型,这两种冲突的解决要求当前实行紧缩国内支出政策和人民币升值政策的配合。因此,汇率政策的选择就变得至关重要。当然要解决当前经济内外均衡冲突,还需要其他政策的配合。     

Is Competition Engaging? Examining the Interactive Effects of Goal Orientation and Competitive Work Environment on Engagement

Contemporary work environments are growing increasingly competitive. However, some employees may “fit” with such environments better than others. This study examined how the relationship between employees’ goal orientations (learning, proving, and avoidance) and engagement is influenced by the competitive environment of their workplace. By investigating the interactive effect of goal orientation and competitive work environment, this research expands our understanding of factors leading to engagement. We tested our model using a sample of 345 working adults from a variety of organizations across several different industries. Results indicate that learning goal orientation was positively related to engagement while avoidance goal orientation was negatively related to engagement. Competitive work environment (CWE) interacted with learning orientation and proving orientation to predict engagement. We conclude with a discussion of the implications of our results for human resource management. © 2015 Wiley Periodicals, Inc.     

Worlding Water Supply: Thinking Beyond the Network in Jakarta

This article draws on scholarship in Southern theory to ‘world’ the study of water’s urbanization. This means complicating scholarship by widening the focus beyond the application of Northern norms to engage with complex and diverse practices in Southern cities. For water’s urbanization, this means focusing on what water supply is for the majority: neither the centralized piped‐water network nor its absence, but the range of practices and technologies that unite people, nature and artefacts in a complex socio‐ecological politics of water. Drawing on scholarship from Southern urbanisms, urban political ecology, and science and technology studies, we illustrate how expanding water’s urbanization to include more than networked infrastructure in Jakarta draws attention to the importance of ecological connections between piped water, groundwater, wastewater and floodwater. Thinking beyond the network requires deeper engagement with the ecological connections between the diverse flows of water in and around urban environments. These produce distinct forms of fragmentation that are missed when analysis is limited to piped‐water supply. The emphasis on ecological connections between flows of water and power seeks to draw attention back to the importance of the uneven exposure to environmental hazards in cities in which neither water nor nature are wholly contained by infrastructure.     

金融集聚促进了技术创新吗？

在促进经济总量提升的表象下,金融集聚对经济持续高质量增长的源泉——技术创新是否依然有促进作用？结合新经济地理学与金融地域运动理论,系统梳理金融集聚的作用机理,并选用我国1998—2015年的省级面板数据,以金融集聚对经济增长的影响为参照,实证检验及分析金融集聚对技术创新的影响,结果表明：金融集聚虽然对经济总量的快速增长有促进作用,但会抑制经济可持续发展所必需的技术创新;金融集聚存在空间分布不均衡的特征,东部地区集聚程度远高于中西部地区;金融行业集聚的作用效果不一,银行业和保险业集聚对技术创新有显著的促进作用,证券业集聚则会逆向挤出技术创新;在克服自选择问题后,金融集聚对技术创新的真实效果表现为抑制作用下降。     

Supplier qualification for high-value goods and services in Nigeria: a comparison of qualified and non-qualified suppliers

This study set out to understand the capabilities of suppliers of high-value products and services in Nigeria. Supplier capability data were collected from almost 500 potential suppliers across 28 product categories. The findings indicate that only a small minority of potential suppliers achieved the required levels of performance and that very few companies have suitable operational capabilities or corporate citizenship behaviour. Furthermore, significant differences were found between service suppliers and product suppliers with regard to performance. The findings suggest that the majority of suppliers of products and services in Nigeria need to improve their operational capabilities and corporate citizenship behaviours, or else risk losing their ability to compete in a changing market place with new barriers to entry.
