从传播学视角探析自媒体时代的“网络红人”现象

随着多媒体技术的发展,大众信息传播与分享的方式发生了翻天覆地的变化。现今的信息传播方式以个体为中心,具有高度互动性和参与性。进入了自媒体时代,尤其是微博、微信等私人化网络媒体的出现,给了普通民众更多话语权和高度参与的机会,由此也直接促进了一批批“网络红人”的出现。每一个“网络红人”的出现,总能在虚拟世界以及现实世界掀起阵阵舆论波澜,也引来了媒体的蜂拥报道。如何正确看待“网络红人”现象,减少其负面影响,使其发挥积极、正面的作用,亟需社会的关注。     

INSTITUTIONAL WAGE EFFECTS: REVISITING UNION AND BARGAINING COUNCIL WAGE PREMIA IN SOUTH AFRICA

The literature on the union wage gap in South Africa is extensive, spanning a range of data sets and methodologies. There is, however, little consensus on the appropriate method to correct for the endogeneity of union membership or the size of the union wage gap. Furthermore, there are very few studies on the bargaining council wage premium in South Africa because of lack of data on the coverage of employees under these agreements. Our study, using 2005 Labour Force Survey data, firstly reconsiders the union wage gap controlling for both firm‐level and job characteristics. When correcting for the endogeneity of union status through a two‐stage selection model and including firm size, type of employment, and non‐wage benefits, we find a much lower union wage premium for African workers in the formal sector than premiums reported in some previous studies. Secondly, our study estimates bargaining council wage premiums for the private and public sectors. We find that extension procedures are present in both private and public bargaining council systems but that unions negotiate for additional gains for their members at the plant level. Furthermore, there is some evidence that unions negotiate for awards for their members in the private sector irrespective of bargaining council coverage.     

Corporate lobbying in the UK: an analysis of attitudes towards the ASB's 1995 deferred taxation proposals

This paper models corporate lobbying behaviour with respect to the ASB's 1995 discussion paper on deferred taxation. The study makes improvements to the methodology applied in prior studies. It expands the definition of lobbying beyond the submission of comment letters. It extends the analysis to control for past lobbying behaviour. It uses multinomial logistic regression to consider those companies lobbying in favour, those lobbying against, and those that did not lobby. The findings suggest that size and past lobbying behaviour are key determinants of the decision to lobby. In addition, companies that lobbied against the proposals were more likely to have debt covenants than were those that lobbied in favour. Debt covenants, however, did not explain the difference between non-lobbyists and lobbyists against. Companies that lobbied in favour were more likely to experience incentive compensation effects than were those that lobbied against. There was some evidence of the influence of US listing.

Wage bargaining and inflation

This paper investigates the issue of time inconsistency of monetary policy in a game with perfect information and infinite repetitions. The private sector is described by a wage negotiation process between a labour union and a firm. Unlike in the standard literature, the model has the feature that as the distortion of the economy gets larger, namely as the bargaining power of the union increases, the reputational equilibrium with low inflation becomes more likely to occur. This finding is consistent with the observation that higher levels of the labour cost are not typically associated with higher levels of inflation.     

Promoting healthy eating to children: a text message (SMS) feedback approach

The paper presents the design and results of a goal‐setting and feedback intervention aimed at increasing consumption of fruits and vegetables. The intervention involved 256 Danish adolescents (aged 12), and consisted of a nutrition education programme and an SMS‐based diary and feedback procedure that involved setting and modifying consumption goals. Effects were measured by comparing consumption goals and consumption data from the SMS diaries as well as from pre‐ and post‐intervention surveys. In addition to assessing the effects of the intervention on the consumption of fruits and vegetables, an objective of the study was to evaluate the intervention process in terms of attrition and goal accommodation behaviours. Based on the pre‐intervention survey, the sample was split into two groups consisting of pupils with low vs. high intake of fruits and vegetables. The diary and feedback design resulted in low attrition for both groups of pupils. Contrary to expectations, however, pupils with a high vs. low pre‐intervention intake were not less likely to reduce their intake goals during the intervention. For the pupils with low pre‐intervention intake, the intervention resulted in small but significant increases in consumption frequencies, whereas the partial effect of the SMS routines was only marginally positive. Unexpectedly, the pupils with a high pre‐intervention intake reduced their consumption of fruits and vegetables during the intervention.

Performance measurement of pension strategies: a case study of Danish life cycle products

The Danish pension markets of life cycle products have expanded considerably since its introduction in the beginning of the millennium. The market is maturing and pensioners have the choice between a wide area of different products. It is therefore about time that financial insurance technology is developed to guide the performance measurement of available products. In this paper we develop a simple first version of such a method and we investigate life cycle products recommended on the web of the four biggest commercial Danish pension companies on one day in February 2007. All considered products are outperformed by trivial benchmark products with constant stock proportion over time. Our approach is the following: for each life cycle product we first find a trivial benchmark product with the same long-term risk and then we compare the long-term return of the two equivalent products. We primarily consider value at risk and tail value at risk as risk measures, but we also include a study where the fair value of an interest guarantee is used as risk measure. We consider both long-term mean returns and long-term median returns. We hope that our new method will be regarded as a first step towards a scientifically based ranking of the quality of pension products.     

对高职院校岗位设置管理实践的一点思考

随着事业单位人事制度改革不断深入,继实行全员聘用制度后,围绕收入分配制度改革这一核心,国家在事业单位开展了岗位设置管理工作,对包括高校在内的各类事业单位的发展起到了重要的促进和推动作用。同时,由于体制机制及政策层面等多方面原因,岗位设置管理工作还存在一些不足和问题,应通过深入调研并结合工作实践,采取相关建议和措施完善高职院校岗位设置管理工作。     

矿业权设置方案布局优化评估研究——以云南保山-龙陵地区铅锌矿勘查示范区为例

云南保山一龙陵地区目前已设置探矿权18个,主攻矿种为铅锌矿,已有铅锌矿探矿权共9个;优化方案拟设探矿权区块31个,其中铅锌矿及铅矿共17个。已有探矿权区块中54-位于禁止区内的探矿权区块要经调整逐步退出禁止区。编制实施该矿业权设置方案,从源头上杜绝大矿小开,解决矿业权布局不合理问题,增强矿业权设置的主动性和合理性,实现矿产资源开发整合常态化管理。编制方案应重点把握：（1）认真学习合规性审查文件;（2）整体布局,统筹把握新旧矿业权的设置与整合;（3）矿业权设置的合理性宜依据区块地质背景及物化探特征编写;（4）应处理好矿业权重叠问题;（5）及时查重,优化主攻与非主攻矿种的布局。
