The instrumental benefits of firm’s CSR activities are contingent upon the stakeholders’ awareness and favorable attribution. While social media creates an important momentum for firms to cultivate favorable awareness by establishing a powerful framework of stakeholder relationships, the opportunities are not distributed evenly for all firms. In this paper, we investigate the impact of CSR credentials on the effectiveness of social media as a stakeholder-relationship management platform. The analysis of Fortune 500 companies in the Twitter sphere reveals that a higher (...) CSR rating is a strong indicator of an earlier adoption, a faster establishment of online presence, a higher responsiveness to the firm’s identity, and a stronger virality of the messages. Incidentally, the higher CSIR rating is also found to be associated with the stronger virality. Our findings also suggest that socially responsible firms can harvest proactive stakeholders’ participation without investing more resources. As the first study that conceptualizes the social media as a proponent of CSR, this paper contends that “being socially responsible” makes more practical sense for firms with the rise of social media.

Comparative Political Theory and Cross-Cultural Philosophy explores new forms of philosophizing in the age of globalization by challenging the conventional border between the East and the West, as well as the traditional boundaries among different academic disciplines. This rich investigation demonstrates the importance of cross-cultural thinking in our reading of philosophical texts and explores how cross-cultural thinking transforms our understanding of the traditional philosophical paradigm.

River water pollution by wastewater can cause significant negative impact on the aquatic sustainability. Hence, accurate modeling of this complicated system and its cost-effective treatment and reuse decision is very important because this optimization process is related to economic expenditure, societal health, and environmental deterioration. In order to optimize this complex system, we may consider three treatment or reuse options such as microscreening filtration, nitrification, and fertilization-oriented irrigation on top of two existing options such as settling and biological oxidation. The (...) objective of this environmental optimization is to minimize the economic expenditure of life cycle costs while satisfying the public health standard in terms of groundwater quality and the environmental standard in terms of river water quality. Particularly, this study improves existing optimization model by pinpointing the critical deficit location of dissolved oxygen sag curve by using analytic differentiation. Also, the proposed formulation considers more practical constraints such as maximal size of irrigation area and minimal amount of filtration treatment process. The results obtained by using an evolutionary algorithm, named a parameter-setting-free harmony search algorithm, show that the proposed model successfully finds optimal solutions while conveniently locating the critical deficit point.

With the advent of responsible business, ensuring social responsibility in sourcing is of interest to both academics and practitioners. In this study, we examine one way of achieving this goal: ethical sourcing initiatives (ESIs). ESIs refer to a firm’s formal and informal actions to manage sourcing processes in an ethical and socially responsible manner. While ESIs have been established as an important part of corporate social responsibility, it is unclear whether, how, and when this corporate effort is economically beneficial. We (...) conduct an event study estimating the shareholder value effect of 159 publicly traded firms’ ESIs and find that the stock market reacts positively to ESIs in general. We also compare market reactions under different conditions including reactive versus proactive ESIs, and their interactions with initiative timing, firm size, and financial risk. Additionally, we find that ESIs are associated with long-term stock price and operating performance. Overall, our findings clarify the potential economic benefits of corporate ESIs and encourage buying firms to take these initiatives selectively according to business contexts. (shrink)

This longitudinal study examined the development of moral judgement in 37 nursing students attending a university in Suwon, Korea. The participants completed the Korean version of the Defining Issues Test to allow analysis of their level of moral judgement. The development of moral judgement was quantified using ‘the moral development score’ at each stage (i.e. the six stages detailed by Kohlberg) and the ‘P(%) score’ (a measure of the overall moral judgement level). The results were as follows: (1) the moral (...) development score for stage 5A was consistently the highest across the four years of the students’ course, showing significant differences in some sociodemographic factors including home, birth order and monthly income; and (2) the P(%) score was higher in fourth-year (47.47 ± 11.21) than in first-year (46.13±9.73) students. There was no significant difference in the P(%) score according to sociodemographic factors. Further studies will examine in detail the correlation between curriculum and moral judgement development. We suggest that courses in ethics education should be made more relevant. (shrink)

Cancer chemotherapy has been the most common cancer treatment. However, it has side effects that kill both tumor cells and immune cells, which can ravage the patient’s immune system. Chemotherapy should be administered depending on the patient’s immunity as well as the level of cancer cells. Thus, we need to design an efficient treatment protocol. In this work, we study a feedback control problem of tumor-immune system to design an optimal chemotherapy strategy. For this, we first propose a mathematical model (...) of tumor-immune interactions and conduct stability analysis of two equilibria. Next, the feedback control is found by solving the Hamilton–Jacobi–Bellman equation. Here, we use an upwind finite-difference method for a numerical approximate solution of the HJB equation. Numerical simulations show that the feedback control can help determine the treatment protocol of chemotherapy for tumor and immune cells depending on the side effects. (shrink)

Negation is frequently found in every language, and many logicians or linguists have been carrying out research on it. Their investigations are, however, mostly confined to the languages of Europe. Although some of them pay attention to non-European languages, we can hardly find research on negation in Korean. In this paper, we carry out contra-linguistic analysis of four aspects of negation in Korean and English. First, we compare the expressions of negative elements in Korean and English sentences. Second, we contrast (...) the types of negation in Korean with those of English. Third, we draw a distinction between Korean and English in what decides the scope of negation. Finally, we contrast the answers to questions which contain negative elements. (shrink)

This descriptive study was undertaken to identify the degree of ethical sensitivity of staff nurses and to analyze the differences in ethical sensitivity in terms of both general and ethics-related characteristics. Participants were 236 staff nurses working in general hospitals in Korea. Ethical sensitivity was measured by means of an instrument developed by the researchers. The results showed that the mean score for the degree of ethical sensitivity was 0.71 out of a possible maximum score of 1 (range 0.30 to (...) 0.97). For general characteristics, there was a significant difference in ethical sensitivity according to age (F (df 2233)-3.99, P-0.02). For characteristics related to ethics, there was a significant difference in ethical sensitivity according to attitude towards the nursing profession (F (df 4231)-2.94, P-0.03). It is therefore recommended that a training program reflecting these variables be developed to enhance staff nurses’ ethical sensitivity. (shrink)
