Functional and emotional traits of corporate social media message strategies: Behavioral insights from S&P 500 Facebook data

Drawing from literature regarding public engagement, the Elaboration Likelihood Model (ELM), computer-mediated communication research, and emotion psychology, this study examines the effects of companies’ social media communication strategies on public engagement behaviors as indexed by post likes, shares, and comments. Specifically, it investigates how corporate Facebook posts’ functional traits (functional interactivity and vividness) and emotional traits (emotion presence, valence, and strength) impact public engagement online. Through data mining and computer-assisted sentiment analysis of 33,379 posts from 106 Standard & Poor 500 companies’ Facebook accounts, this study finds a negative effect of functional interactivity but a positive effect of vividness on engagement. It also shows that emotional traits overall yield stronger public engagement outcomes. Two-way interactions between emotional and functional features are also detected. Theoretical and practical implications are discussed.     

社区治理主体问关系:问题、成因与重构

社区治理主体间关系是一个关乎社区治理绩效的重要问题.当前我国社区治理主体间存在着权力冲突、关系混乱的状态,不利于推进社区的和谐与发展.社区治理主体间关系存在问题的直接原因在于社区治理明显的"行政化倾向",而这又根源于我国传统计划经济体制、行政管理体制以及文化观念的影响.要理顺社区治理主体间关系,需要综合平衡各种社区治理...     

渠道管理过程中的关系导向

市场营销的渠道管理经历了生产导向、产品导向、客户导向的发展阶段,正朝关系导向发展。关系导向主张渠道成员之间、渠道与顾客之间关系紧密、信息畅通、利益共享。它通过同时满足市场营销渠道每个环节上的需求来让渡交换价值,并通过使顾客满意与顾客建立长期的关系而创造利润。通过关系导向渠道成员可以获得差异优势,主要表现为创新优势、服务优势、柔性优势,为建设关系导向的渠道管理,渠道成员必须坚持创新、激励、信息沟通和企业文化的认同。     

对抗与合作：孟子对君臣关系的新建构

孟子对君臣关系的新建构,一方面经由手足—腹心、犬马—国人、土芥—寇雠的论述,凸显了对抗的一面,土芥—寇雠之论又最让统治者胆战心惊;另一方面通过师、友、事的评析,显示了合作的一面,师友之论又最让士阶层心往神驰。既对抗又合作的复杂关联,现实地展开于士阶层参与政治的具体实践之中。孟子器重师道,强调智识分子以道尊于势的理想来应对势强于道的现实,从外王转向了内圣。这实质上是孟子的义仕派立场以及王道政治学遭遇现实困顿之后的必然转向。     

从功能需求看西方社会学理论研究视角的转换

可以用功能取向为线索梳理西方社会学理论发展的历史脉络.西方社会学理论研究视角的转换是随时代的变迁而不断转向的,迄今为止,西方社会学理论发展大致可以分为萌芽、成熟、发展和放飞四个阶段.与时代接轨,与现实相连是社会学理论生存和发展的惟一条件.     

从功能对等角度分析《水浒传》英译本中常见修辞手法的处理——以登特·杨的译本为例

《水浒传》中运用了大量的修辞手法,在增加了艺术感染力的同时,也给小说的翻译增添了难度。奈达的功能对等,是指译文对译文接受者所起的作用与原文对原文接受者所起的作用大体对等。本文以登特．杨父子合译的《水浒传》新译本为例,运用奈达的功能对等理论,对《水浒传》英译本中常见修辞手法的翻译处理进行分析。     

Invariant co-ordinate selection

Summary.  A general method for exploring multivariate data by comparing different estimates of multivariate scatter is presented. The method is based on the eigenvalue–eigenvector decomposition of one scatter matrix relative to another. In particular, it is shown that the eigenvectors can be used to generate an affine invariant co-ordinate system for the multivariate data. Consequently, we view this method as a method for invariant co-ordinate selection . By plotting the data with respect to this new invariant co-ordinate system, various data structures can be revealed. For example, under certain independent components models, it is shown that the invariant co- ordinates correspond to the independent components. Another example pertains to mixtures of elliptical distributions. In this case, it is shown that a subset of the invariant co-ordinates corresponds to Fisher's linear discriminant subspace, even though the class identifications of the data points are unknown. Some illustrative examples are given.     

Order statistics from trivariate normal and -distributions in terms of generalized skew-normal and skew- distributions

We consider here a generalization of the skew-normal distribution, GSN(λ₁,λ₂,ρ), defined through a standard bivariate normal distribution with correlation ρ, which is a special case of the unified multivariate skew-normal distribution studied recently by Arellano-Valle and Azzalini [2006. On the unification of families of skew-normal distributions. Scand. J. Statist. 33, 561–574]. We then present some simple and useful properties of this distribution and also derive its moment generating function in an explicit form. Next, we show that distributions of order statistics from the trivariate normal distribution are mixtures of these generalized skew-normal distributions; thence, using the established properties of the generalized skew-normal distribution, we derive the moment generating functions of order statistics, and also present expressions for means and variances of these order statistics.Next, we introduce a generalized skew-t_ν distribution, which is a special case of the unified multivariate skew-elliptical distribution presented by Arellano-Valle and Azzalini [2006. On the unification of families of skew-normal distributions. Scand. J. Statist. 33, 561–574] and is in fact a three-parameter generalization of Azzalini and Capitanio's [2003. Distributions generated by perturbation of symmetry with emphasis on a multivariate skew t distribution. J. Roy. Statist. Soc. Ser. B 65, 367–389] univariate skew-t_ν form. We then use the relationship between the generalized skew-normal and skew-t_ν distributions to discuss some properties of generalized skew-t_ν as well as distributions of order statistics from bivariate and trivariate t_ν distributions. We show that these distributions of order statistics are indeed mixtures of generalized skew-t_ν distributions, and then use this property to derive explicit expressions for means and variances of these order statistics.     

A note on the equality of the OLSE and the BLUE of the parametric function in the general Gauss–Markov model

In this note we consider the equality of the ordinary least squares estimator (OLSE) and the best linear unbiased estimator (BLUE) of the estimable parametric function in the general Gauss–Markov model. Especially we consider the structures of the covariance matrix V for which the OLSE equals the BLUE. Our results are based on the properties of a particular reparametrized version of the original Gauss–Markov model.      

Forecasting obesity trends in England

Summary.  Forecasts of trends in obesity in England for 2010 are produced by treating the available data, which contain the proportions of the population, categorized by age and sex, falling into different body mass index ranges, as compositional data sets, so that the implicit simplex restrictions are automatically satisfied. Forecasts are calculated by using linear trend models for the log-ratio transformations and are accompanied by prediction regions. The advantages of treating data on proportions compositionally are emphasized and compared with forecasts that have been obtained by ignoring this restriction.
