Forecasting blood glucose values for patients can help prevent hypoglycemia and hyperglycemia events in advance. To this end, this study proposes an intelligent ensemble deep learning system to predict BG values in 15, 30, and 60 min prediction horizons based on historical BG values collected via continuous glucose monitoring devices as an endogenous factor and carbohydrate intake and insulin administration information as exogenous factors. Although there are numerous deep learning algorithms available, this study applied five algorithms, namely, recurrent neural network, (...) which is optimized for sequence data, and RNN-based algorithms, stacked LSTM, bidirectional LSTM, and gated recurrent unit). Then, a genetic algorithm was applied to the five prediction models to optimize their weights through ensemble techniques and to yield the final predicted BG values. The performance of the proposed model was compared to that of the autoregressive integrated moving average model as a baseline. The results show that the proposed model significantly outperforms the baseline in terms of the root mean square error and continuous glucose error grid analysis. For the valid 29 diabetic patients for the multivariate models, the RMSE was 11.08, 19.25, and 31.30 mg/DL for 15, 30, and 60 min PH, respectively. When the same data were applied to univariate models, the RMSE was 11.28, 19.99, and 33.13 mg/DL for 15, 30, and 60 min PH, respectively. Both the univariate and multivariate models showed a statistically significant difference compared with the baseline at a 5% statistical significance level. Instead of using a model with a single algorithm, applying a GA based on each output of a model with multiple algorithms was found to play a significant role in improving model performance. (shrink)

Four Daoist texts illustrate the dynamic image of the Daoist immortal world on which a Daoist environmental ethics can be built. The first text is the Daodejing with two of the oldest commentaries. The second is Tao Hongjing’s Diagram of Rank and Functions of True Spirits. The third is the collection of poems by Immortal Changchun, titled Panxiji. The fourth is the Morning and Evening Liturgical Prayer Book of the Quanzhen Order, which represents Daoist ecological concerns for the natural world. (...) Daoism not only accords with the impetus and spirit of environmental ethics but can also make a concrete contribution to its implementation. (shrink)

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)

Background Nurses providing care to patients with end-of-life or terminal illnesses often encounter ethically challenging situations leading to moral distress. However, existing quantitative studies have examined moral distress using instruments that address general clinical situations rather than those specific to end-of-life care. Furthermore, qualitative studies have often been limited to participants from a single unit or those experiencing moral distress-induced circumstances. A comprehensive and integrated understanding of the overarching process of moral distress is vital to discern the unique circumstances surrounding (...) end-of-life care and its consequential impacts. Research objectives To explore the moral distress experiences of nurses who are frequently involved in caring for patients with end-of-life or terminal illnesses and apply it to two existing theories: the model of moral distress and the ecological model. Research design A qualitative descriptive approach was employed. Participants and research context Seven focus group interviews involving 30 nurses were performed. The subsequent transcriptions underwent rigorous content analysis. Ethical considerations We obtained Institutional Review Board approval from a university. Focus group interviews were conducted with nurses who agreed to participate and signed the consent form. Findings The moral distress-inducing factors and nurses’ perceived impact of moral distress were identified and categorized based on moral distress theories and ecological models. A total of 15 categories and 30 subcategories across the following 4 domains were derived: (1) intrapersonal, (2) interpersonal, (3) organizational, and (4) structural factors. Conclusions End-of-life-specific circumstances induced moral distress among nurses, with both negative and positive impacts identified. Effective organizational and policy support is essential to manage conflicts, form a healthy organizational culture, provide training, and prevent unnecessary expenses due to the negative consequences of moral distress.

This paper examines the antecedents of organizational commitment for adopting corporate environmental responsibility and green practices in the case of the logistics industry in South Korea. Seven hundred and eighty employees and top management from logistics companies were sampled. The data were analyzed using factor analysis, structural equation modeling techniques, and one-way analysis of variance. The results showed that social expectations, organizational support, and stakeholder pressure were the important antecedents for the adoption of corporate environmental responsibility and green practices. In (...) the path analysis, social expectations had the greatest impact on both stakeholder pressure and green practice adoption. Moreover, we found that the higher the job titles were, the more willing they were to adopt green practices. This indicated that the current top management of Korean logistics companies is well aware of being mandated to make a commitment to corporate environmental responsibility and green practices.

Background:While nursing ethics education is commonly provided for undergraduate nursing students in most nursing colleges, consensus on the content and teaching modules for these ethics courses have still not been established.Objectives:This study aimed to examine the effects of nursing ethics education on the moral sensitivity and critical thinking disposition of nursing students in Korea.Research design:A one-group pre- and post-test design was used. Moral sensitivity was measured using the Korean version of the Moral Sensitivity Questionnaire. Critical thinking disposition was measured using (...) the Critical Thinking Disposition Questionnaire.Participants and research context:Participants were 70 undergraduate nursing students who were attending a university located in Seoul, Korea. The nursing ethics education was provided 7 times, from September to December 2010, and comprised 90-min sessions each week.Ethical considerations:This study was conducted in accordance with the Human Subject Research Ethics Committee guidelines.Findings:After the education, the levels for the patient-oriented care, a sub-domain of moral sensitivity, and inquisitiveness, a sub-domain of critical thinking disposition, significantly improved. There were no changes in overall scores for moral sensitivity and critical thinking disposition. There were significant positive correlations between moral sensitivity and critical thinking disposition both pre- and post-intervention.Conclusion:These results reflect the need for ongoing efforts to develop innovative content, structure, and instructional methods for undergraduate nursing ethics education programs.

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.

The present study develops an artificial agent that plays the iterative chicken game based on a computational model that describes human behavior in competitive social interactions in terms of fairness. The computational model we adopted in this study, named as the self-concept fairness model, decides the agent’s action according to the evaluation of fairness of both opponent and self. We implemented the artificial agent in a computer program with a set of parameters adjustable by researchers. These parameters allow researchers to (...) determine the extent to which the agent behaves aggressively or cooperatively. To demonstrate the use of the proposed method for the investigation of human behavior, we performed an experiment in which human participants played the iterative chicken game against the artificial agent. Participants were divided into two groups, each being informed to play with either a person or the computer. The behavioral analysis results showed that the proposed method can induce changes in the behavioral pattern of human players by changing the agent’s behavioral pattern. Also, we found that participants tended to be more sensitive to fairness when they played with a human opponent than with a computer opponent. These results support that the artificial agent developed in this study will be useful to investigate human behavior in competitive social interactions. (shrink)

DNA damage repair within telomeres are suppressed to maintain the integrity of linear chromosomes, but the accidental activation of repairs can lead to genome instability. This review develops the concept that mechanisms to repair DNA damage in telomeres contribute to genetic variability and karyotype evolution, rather than catastrophe. Spontaneous breaks in telomeres can be repaired by telomerase, but in some cases DNA repair pathways are activated, and can cause chromosomal rearrangements or fusions. The resultant changes can also affect subtelomeric regions (...) that are adjacent to telomeres. Subtelomeres are actively involved in such chromosomal changes, and are therefore the most variable regions in the genome. The case of Caenorhabditis elegans in the context of changes of subtelomeric structures revealed by long‐read sequencing is also discussed. Theoretical and methodological issues covered in this review will help to explore the mechanism of chromosome evolution by reconstruction of chromosomal ends in nature. (shrink)

Storytelling is getting increasing attention as one of the effective strategies for revitalizing the local festivals and even regional economies. Yet, the mechanisms through how storytelling helps the success of local festivals are still relatively less known. Using the data from 322 individuals who participated in local festivals using storytelling, our results showed that local festival storytelling is positively related to tourists’ revisit intention. Furthermore, the positive relationship between local festival storytelling and tourists’ revisit intention was serially mediated by authenticity (...) and positive emotion. Theoretical and practical implications are discussed. (shrink)

Pathological gaming among adolescents has been reported to hamper the achievement of a balanced life and to threaten the development of social competencies. Despite the increasing social concerns on the adolescent users, however, the mechanism of gaming behavior of adolescents has not been sufficiently examined. This study explored the mechanism of pathological gaming among adolescents from 3-year longitudinal data of 778 Korean adolescent gamers, by analyzing the effects of negative affects on the degree of pathological gaming through the mediation variables (...) based on the stimulus-organism-response framework. Latent class analysis was used to uncover potential risk groups, and through partial least squares-structural equation modeling analysis, the mediation pathways to pathological gaming were compared between the risk group and the non-risk group. The results highlighted the key role of academic stress on the degree of pathological gaming. In the entire group, academic stress primarily increased pathological gaming through self-control. The mediation path of self-control was the most influential result in the risk group. Aggression was the key mediator between loneliness and pathological gaming in the non-risk group. The theoretical and practical implications of the results were discussed. (shrink)

Theories of ethical leadership provide important insights about the effect of leader’s ethics on the relationship between leaders and followers. However, there is an increasing demand for addressing key constructs that enhance the capacity to explain theoretical aspects of ethical leadership. The purpose of this study is to expand the theoretical framework of ethical leadership based on Korean traditional leadership by focusing on personal cultivation, morality, and social responsibility. Using a framework of intrapersonal process as leadership and core value and (...) competence as components of leadership, this study examines the ethical aspects of Korean traditional leadership and provides the implications to further develop the theory of ethical leadership. It is found that ethical integrity ensued from sugi is an essential precondition to develop leadership, and the core value of ethical leadership includes Zhixin-Chijing and the competence co..

If, today, ‘politics is in culture and culture is relentlessly political’ (Brown, 2002), if the domains of ‘the political’ and ‘the cultural’ can no longer be easily distinguished or kept separate, then contemporary political theory requires an understanding and analysis of cultural politics. This essay undertakes the first stages of such a project by trying to theorize ‘cultural politics’. I argue that ‘cultural politics’ proves to be an object of discourse — it indeed has a certain discursive existence — but (...) not an object of discipline, since no single field or discipline produces it as an object of knowledge. I read this disciplinary failure optimistically, arguing that the study of cultural politics requires a reorientation of theory. The sort of interdisciplinary and multiple-genre work needed to study cultural politics produces a conception of theory as fugitive. Fugitive theory must travel among disciplines, calling on a variety of theoretical and political resources to sustain itself; it refuses the very notion of ‘applied’ theory, insisting that theory ‘is already at work’ in politics (Butler, 1997). To link politics to culture is to practise fugitive theory. And the practice of fugitive theory therefore has the capacity to reveal and explore the workings of cultural politics. (shrink)

Businesses increasingly rely on algorithms that are data-trained sets of decision rules (i.e., the output of the processes often called “machine learning”) and implement decisions with little or no human intermediation. In this article, we provide a philosophical foundation for the claim that algorithmic decision-making gives rise to a “right to explanation.” It is often said that, in the digital era, informed consent is dead. This negative view originates from a rigid understanding that presumes informed consent is a static and (...) complete transaction. Such a view is insufficient, especially when data are used in a secondary, noncontextual, and unpredictable manner—which is the inescapable nature of advanced artificial intelligence systems. We submit that an alternative view of informed consent—as an assurance of trust for incomplete transactions—allows for an understanding of why the rationale of informed consent already entails a right to ex post explanation.

We offer a precautionary account of why business managers should proactively rethink about what kinds of automation firms ought to implement, by exploring two challenges that automation will potentially pose. We engage the current debate concerning whether life without work opportunities will incur a meaning crisis, offering an argument in favor of the position that if technological unemployment occurs, the machine age may be a structurally limited condition for many without work opportunities to have or add meaning to their lives. (...) We term this the axiological challenge. This challenge, if it turns out to be persuasive, leads to a second challenge, to which managers should pay special attention: the teleological challenge, a topic especially relevant to the broad literature about corporate purpose and governance. We argue that both the shareholder profit-maximization model and its major alternative, stakeholder theory, are insufficient to address the meaning crisis. Unless rebutted, the two challenges compel business leaders to proactively rethink the purpose of business for future society. Otherwise, businesses will be contributors to a major ethical crisis and societal externality in the coming society. (shrink)

Integrative social contracts theory is a novel approach to normative questions and has been widely evaluated, discussed, and applied by academics and practitioners alike. While the "I" in ISCT leads the title, it has not received the analytical attention it deserves, especially since the "integrative" component in ISCT is multifaceted and at the conceptual core of the theory. In this paper we therefore take a closer look at two facets of integration. First, we examine the normative integration that takes place (...) in ISCT. For our analysis we draw on theories of legitimacy and obligation. Second, given that empirical inquiry is an important part of the normative integration, we take a closer look at how research that has applied or used ISCT has embraced the empirical components of the theory. This analysis of the normative–empirical integration focuses on problems and realities of empirical inquiry in ISCT. (shrink)

Despite the prevailing discourses on the importance of top management ethical leadership, related theoretical and empirical developments are lacking. Drawing on institutional theory, we propose that top management ethical leadership contributes to organizational outcomes by promoting firm-level ethical and procedural justice climates. This theoretical framework was empirically tested using multi-source data obtained from 4,468 employees of 147 Korean companies from various industries. The firm-level analysis shows that top management ethical leadership significantly predicts ethical climate, which then results in procedural justice (...) climate that fully mediates the effects of top management ethical leadership on two organizational outcomes, namely, firm-level organizational citizenship behavior and firm financial performance. The present study provides a plausible theoretical account and empirical validation of a mechanism through which top management ethical leadership enhances organizational performance. (shrink)

Most management researchers pause at the threshold of objective right and wrong. Their hesitation is understandable. Values imply a “subjective,” personal dimension, one that can invite religious and moral interference in research. The dominant epistemological camps of positivism and subjectivism in management stumble over the notion of moral objectivity. Empirical research can study values in human behavior, but hard-headed scientists should not assume that one value can be objectively better than another. In this article, we invite management researchers to rethink (...) this presumption. We show how accepting at least a limited form of moral objectivity, namely, an epistemic orientation that seeks objective moral reasons, can benefit management research by 1. guiding research practice; 2. using patterns of moral objectivity as clues for formulating empirical hypotheses for psychological explanations; and 3. adding prescriptive power to empirical theories.

ABSTRACT:We argue that Confucianism makes a fundamental contribution to understanding why civility is necessary for a morally decent workplace. We begin by reviewing some limits that traditional moral theories face in analyzing issues of civility. We then seek to establish a Confucian alternative. We develop the Confucian idea that even in business, humans may be sacred when they observe rituals culturally determined to express particular ceremonial significance. We conclude that managers and workers should understand that there is a broad range (...) of morally important rituals in organizational life and that managers should preserve and develop the intelligibility and integrity of many of these rituals.

People are often involuntarily laid off from their jobs through no fault of their own. Employees who are dismissed in this manner cannot always legitimately hold employers accountable for these miserable situations because the decision to implement layoffs is often the best possible outcome given the context—that is, layoffs in and of themselves may be “necessary evils.” Yet, even in circumstances in which layoffs qualify as “necessary evils,” morality demands that employers respect the dignity of those whose employment is involuntarily (...) terminated. In this paper I argue that to preserve the dignity of employees who are involuntarily terminated, in most cases employers have a substantial reason to offer a special kind of unemployment benefit, “severance pay.” To support my claim I draw and expand upon Bernard Williams’s analysis of “agent-regret,” which I believe greatly helps to address and articulate employers’ obligations in the context of involuntary termination.

ABSTRACT:We discuss workers’ dignity in hierarchical organizations. First, we explain why a conflict exists between high-ranking individuals’ authority and low-ranking individuals’ dignity. Then, we ask whether there is any justification that reconciles hierarchical authority with the dignity of workers. We advance a communitarian justification for hierarchical authority, drawing upon Confucianism, which provides that workers can justifiably accept hierarchical authority when it enables a certain type of social functioning critical for the good life of workers and other involved parties. The Confucian (...) communitarian perspective shows that promoting workers’ good life or well-being is an important condition for protecting their dignity. (shrink)

ABSTRACT:In this article I inquire into Confucian ethics from a non-ideal stance investigating the complex interaction between Confucian ideals and the reality of the modern workplace. I contend that even Confucian workers who regularly engage in social rites at the workplace have an internal, Confucian reason to appreciate the value of rights at the workplace. I explain, from a Confucian non-ideal perspective, why I disagree with the presumptuous idea that labor rights are necessarily incompatible with Confucian ideals and values. Specifically, (...) I argue that if managers were “sages,” the highest moral exemplars and authorities in the Confucian tradition, they would perceive that social rituals alone are often not a contextually intelligent and valued response for the development of intimate communities in the modern workplace. The sage perspective will lead Confucian managers to realize, from their own moral perspective, that they have good reason to balance rites with rights, so long as the adoption is extrinsically valuable and consistent with the Confucian ideal. This article contributes to the debates about Confucianism's compatibility with rights, helps Western human rights scholars better contextualize their arguments in Confucianism-influenced cultures, and contributes to the development of a Confucian or Chinese approach to business ethics.

ABSTRACT:In this article we investigate a philosophical problem for normative business ethics theory suggested by a phenomenon that contemporary psychologists call “bounded ethicality,” which can be identified with the putative fact that well-intentioned people, constrained by psychological limitations, make ethical choices inconsistent with their own ethical beliefs and commitments. When one combines the idea that bounded ethicality is pervasive with the idea that a person morally ought to do something only if she can, it raises a doubt about the practical (...) relevance of the moral principles that business ethics theory prescribes. We call this doubt the Radical Behavioral Challenge. It consists in the idea that people cannot generally conform to the normative ethical principles that business ethics theorists prescribe, and that these principles are therefore practically irrelevant. We answer the Radical Behavioral Challenge and explore normative implications of our answer. (shrink)

This study focuses on CEO hubris and its detrimental effect on corporate financial performance along with an examination of critical corporate governance contingencies that may moderate the negative effect. From 654 observations of 164 Korean firms over the years 2001–2008, we found that CEO power exacerbated the negative effect of CEO hubris on corporate financial performance, whereas board vigilance mitigated it. This study provides empirical evidence that entrenchment problems arising from CEO hubris would be exacerbated as CEOs become more powerful, (...) but weakened as board of directors become more vigilant. Theoretical contributions and practical implications will be discussed. (shrink)

Recently, business organizations have increasingly turned to a novel form of non-monetary incentives—that is, “gamification,” which refers to a motivation technique using video game elements, such as digital points, badges, and friendly competition in non-game contexts like workplaces. The introduction of gamification to the context of human resource management has immediately become embroiled in serious moral debates. Most notable is the accusation that using gamification as a motivation tool, employers exploit workers. This article offers an in-depth analysis of the moral (...) charge of exploitation. This article maintains that there are no clear grounds for believing that gamification of labor is exploitative and that if gamification of labor involves a wrong or vice, it must be something other than exploitation.

Background: There is increasing evidence to support the efficacy of transcranial direct current stimulation applications in cognitive augmentation and rehabilitation. Neuromodulation achieved with tDCS may further regulate regional cerebral perfusion affiliated through the neurovascular unit; however, components of cerebral perfusion decrease across aging. A novel neuroimaging approach, functional near-infrared spectroscopy, can aid in quantifying these regional perfusional changes. To date, the interaction of the effects of tDCS on cognitive performance across the lifespan and obtained fNIRS hemodynamic responses remain unknown.Objective: This (...) review aims to examine the effects of tDCS on cognitive performance and fNIRS hemodynamic responses within the context of cognitive aging.Methods: Six databases were searched for studies. Quality appraisal and data extraction were conducted by two independent reviewers. Meta-analysis was carried out to determine overall and subgroup effect sizes.Results: Eight studies met inclusion criteria. The overall effect size demonstrates that tDCS can alter cognitive performance and fNIRS signals, with aging being a potential intermediary in tDCS efficacy.Conclusion: From the studies included, the effects of tDCS on cognitive performance and fNIRS metrics are most prominent in young healthy adults and appear to become less robust with increasing age. Given the small number of studies included in this review further investigation is recommended. (shrink)

The massive introduction of artificial intelligence has triggered significant societal concerns, ranging from “technological unemployment” and the dominance of algorithms in the work place and in everyday life, among others. While AI is made by humans and is, therefore, dependent on the latter for its purpose, the increasing capabilities of AI to carry out productive activities for humans can lead the latter to unwitting slavish existence. This has become evident, for example, in the area of social media use, where AI (...) programmers tie psychology and persuasion to the human social need for approval and validation in ways that few users can resist. We argue that AI should serve humans with humans as masters and not the other way around. Moreover, we propose that virtue ethics might play a role to solidify the human as master of AI and guard against the alternative of AI as the master. (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)
