Maximizing Business Returns to Corporate Social Responsibility (CSR): The Role of CSR Communication

By engaging in corporate social responsibility (CSR) activities, companies can not only generate favorable stakeholder attitudes and better support behaviors (e.g. purchase, seeking employment, investing in the company), but also, over the long run, build corporate image, strengthen stakeholder–company relationships, and enhance stakeholders' advocacy behaviors. However, stakeholders' low awareness of and unfavorable attributions towards companies' CSR activities remain critical impediments in companies' attempts to maximize business benefits from their CSR activities, highlighting a need for companies to communicate CSR more effectively to stakeholders. In light of these challenges, a conceptual framework of CSR communication is presented and its different aspects are analyzed, from message content and communication channels to company- and stakeholder-specific factors that influence the effectiveness of CSR communication.     

Blocking Rumor by Cut

In this paper, a rumor blocking problem is studied with an objective function which is neither submodular or supermodular. We will prove that this problem is NP-hard and give a data-dependent approximation with sandwich method. In addition, we show that every set function has a pair of monotone nondecreasing modular functions as upper bound and lower bound, respectively.     

Optimal RSUs deployment with delay bound along highways in VANET

In order to broadcast an alert message from the accident site to the control center as soon as possible, the roadside units (RSUs) act as the critical component in vehicular ad hoc networks (VANETs). It is not possible to make a pervasive RSU deployment due to the huge cost and market requirement. Hence, how to deploy a minimum number of RSUs in a given region becomes a challenge problem. In this paper, we present an analysis for the total delay of broadcasting alert messages in VANETs along highways. Based on the analysis, the relationship between optimal number of RSUs with the highway distance is given. Moreover, the experiment results verifies the delay analysis and the optimization of RSUs deployment.     

On Shortest k-Edge-Connected Steiner Networks in Metric Spaces

Given a set of points P in a metric space, let l(P) denote the ratio of lengths between the shortest k-edge-connected Steiner network and the shortest k-edge-connected spanning network on P, and let r = inf l(P) P for k 1. In this paper, we show that in any metric space, r 3/4 for k 2, and there exists a polynomial-time -approximation for the shortest k-edge-connected Steiner network, where = 2 for even k and = 2 + 4/(3k) for odd k. In the Euclidean plane, and .

“登山则情满于山,观海则意溢于海”——创作思维特征的精妙阐释

自<文心雕龙>问世以来,注家蜂起,歧见迭出.其中对作为创作总论的<神思>篇的解说更是众说纷纭,见仁见智.文章在细读文本和博取前辈诸家合理内核的基础上,对"神思"作出新的阐释,探求这一艺术构思论的理论价值.认为"神思"指的是在创作构思过程中,作者所具有的一种不受时空限制的自由艺术想象,它作为一种复杂的思维活动,亦呈现出四大特点.     

我国三种野生稻及两个栽培稻品种叶片表面亚显微结构的观察研究

用扫描电钻对原产中国的3种野生稻、2个栽培稻品种就气孔频度、气孔器孔突、大瘤状乳突及木栓细胞乳突等叶片表面亚显微结构作了比较观察研究。结果显示这些性状具有种的特异性,并且其相似程度与亲缘关系远近有关。     

关于解放区文学大众话语形态的历史考察

大众话语是解放区文学的主流叙事方式,但解放区文学中大众话语的浮现并不代表着“大众”已经在文化上已经占据了主体位置。在革命意识形态的绝对权威笼罩下,解放区文学中的“大众”仍然只是被言说的对象,因此,解放区文学的大众话语是一种话语想象的产物。

居民生活能耗增长的分解与影响因素研究——基于习惯形成视角

伴随环境问题的日益紧迫,居民家庭生活中的能耗与碳排放问题逐渐成为今后社会关注的重要方面,通过将居民消费研究领域的习惯形成模型引入到居民生活能耗的分析框架中,计算中国居民生活能耗中的习惯量,研究中国居民生活能耗增长的影响因素。研究结果显示,中国居民生活能耗中存在较大的习惯性成分。通过将居民生活能耗中的习惯因素扣除后,基于协整方程,发现生活能耗中非习惯性成分与中国经济增长和城市化之间是同向变动关系,与工业化是反向变动关系。从降低生活能耗的角度提出了节能减排的相关政策建议,认为:居民的节能消费行为习惯的形成以及节能技术推广应用,在抑制居民生活能耗过快增长中的地位至关重要。
