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.

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.

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.

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)

This longitudinal study examined how nursing students' moral judgment changes after they become qualified nurses working in a hospital environment. The sample used was a group of 80 nursing students attending a university in Suwon, Korea, between 2001 and 2003. By using a Korean version of the Judgment About Nursing Decisions questionnaire, an instrument used in nursing care research, moral judgment scores based on Ketefian's six nursing dilemmas were determined. The results were as follows: (1) the qualified nurses had significantly (...) higher idealistic moral judgment scores than the nursing students; (2) the qualified nurses showed significantly higher realistic moral judgment scores than the nursing students; and (3) when comparing idealistic and realistic moral judgment scores, both the qualified nurses and the nursing students had higher scores for idealistic moral judgment. Further study is recommended to examine changes in moral judgment. (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)

The appearance of mass media and a versatile medium of videos can serve the convenience and instructive information for children; on the other hand, it could abet them in implicit image consumption. Now is the time for kids' to be in need of thinking power which enables them to make a choice, applications andcriticism of information within such visual cultures. In spite of these social changes, the realities are that our curriculum still doesn't meet a learner's demand properly. This research, (...) in this context, is aimed at looking out on the currently implemented art appreciation learning process in a critical fashion, and also aimed at suggesting a plan for visual culture learning by applying the philosophy program for kids as a new alternative. The purpose of such education is toenhance the capability to solve a variety of problems they are facing in the course of daily life by reflecting their matter of concern in a curriculum. What we have to pay attention to in visual culture learning is 'visual literacy.' Such an interpretative faculty of a critical reading of images is a must especially when kids should make a judgment of value hidden in images in their daily events, make an analysis of an ideological message and make an information-oriented decision. Therefore, learners have to enrich their higher-order thinking power as well as critical thinking faculty in modern society. If there is no objection to these social surroundings, it is quite natural that philosophy education, which forms a base of a higher-order thinking for children should be handled significantly at school.

The main purpose of this study was to validate a scale to examine the moral sensitivity of Korean nurses. A pre-existing scale, the Moral Sensitivity Questionnaire (MSQ), developed by Lützén, was used after deletion of three items. The reliability and validity of the scale were examined by using Cronbach’s alpha and factor analysis, respectively. According to the results, reliability of the scale was adequate but its construct validity was not fully supported. Through discussion on evidence of validity, five subconstructs emerged. (...) In particular, unlike the factor structure of the MSQ, two subconstructs, patient-oriented care and professional responsibility, were newly extracted. It was assumed that the other three MSQ subconstructs, conflict, meaning and benevolence (expressed as nurses being ethically good), would not be sensitive to cultural background. Given these findings, interpretations about the meaning of moral sensitivity of Korean nurses are discussed. (shrink)
