The history of press freedom in South Korea has been characterized by periods of chaos. The major media companies in Korea have written a history of shame. Since Japanese colonial rule, freedom of the press has been more often restricted than protected by the laws and policies. There have been four main features of press freedom since 1910: severe restriction during the Japanese colonial rule; experiencing freedom with unstable democracy under the American military rule and the First and Second republics; (...) oppression of the military regimes; and the struggle with capital power since the advent of civilian government. Several decades of Japanese colonial rule, American military rule, and military dictators have influenced the Korean society and the media politically, economically, socially and culturally.

This study seeks effective ways for managing employees with a high Machiavellian personality in organizations by identifying how to enhance their pro-organizational attitudes and behaviors [organizational citizenship behavior ] through transformational leadership. Drawing upon the dual-focused model of TFL, we suggest that exerting TFL upon employees high in Machiavellianism involves ethical dilemmas in that individual-focused and group-focused TFL have contrasting effects on leading pro-organizational attitudes/behaviors among these pro-individual employees. Analysis of data from 184 employees working in South Korea shows that (...) Machiavellianism negatively relates to affective commitment, OCB toward the organization, and OCB toward individuals, but positively to continuance commitment. More importantly, the results reveal that group-focused TFL can effectively manage employees high in Machiavellianism by mitigating the negative relations between Machiavellianism and affective commitment and between Machiavellianism and OCB-O. However, individual-focused TFL strengthens these negative relations as well as the negative relation between Machiavellianism and OCB-I. This study thus shows that to lead employees high in Machiavellianism in a pro-organizational direction, group-focused TFL rather than individual-focused TFL needs to be employed. (shrink)

Although corporate social responsibility appears to be mutually beneficial for companies and consumers, the modern marketplace has left both parties in vulnerable positions. Consumers are increasingly subjected to incongruent CSR messages such as greenwashing, while companies are trapped in a strategic positioning dilemma with regard to how to most effectively and ethically approach CSR communication. This has led some companies to instead adopt a strategically silent approach, such as greenhushing. To capture this CSR positioning dilemma and test the positioning effects (...) on consumers’ attributions, this study applies attribution theory to conceptualize four distinct CSR positions which reflect varying combinations of congruence or incongruence between a company’s external CSR communication and its actual internal CSR actions. Using an online experiment, the effects of the CSR positions on consumer attributions for intrinsic and extrinsic CSR motivations and purchase intentions were tested across three CSR domains: environmental; labor; and lesbian, gay, bisexual, and transgender inclusion. Overall, the findings attest to the significant effect of internal–external congruence-based CSR positioning on how consumers respond to CSR communication. Importantly, the results indicate that discreet positioning is perceived similarly to uniform positioning, while misleading and unethical tactics such as CSR-washing are sure to backfire. Theoretical and managerial implications are discussed. (shrink)

The notions of a C-energetic subset and permeable C-value in BCK-algebras are introduced, and related properties are investigated. Conditions for an element t in [0, 1] to be an permeable C-value are provided. Also conditions for a subset to be a C-energetic subset are discussed. We decompose BCK-algebra by a partition which consists of a C-energetic subset and a commutative ideal.

Graphical AbstractGene editing with engineered nucleases introduce double-strand breaks that are repaired by error-prone nonhomologous end-joining (NHEJ). In article number 1900126, Sara G. Trimidal et al. propose that the length and type or resulting indels can now be controlled by editing with different engineered nucleases or by manipulating the expression of NHEJ genes.

Genome editing with engineered nucleases (GEENs) introduce site‐specific DNA double‐strand breaks (DSBs) and repairs DSBs via nonhomologous end‐joining (NHEJ) pathways that eventually create indels (insertions/deletions) in a genome. Whether the features of indels resulting from gene editing could be customized is asked. A review of the literature reveals how gene editing technologies via NHEJ pathways impact gene editing. The survey consolidates a body of literature that suggests that the type (insertion, deletion, and complex) and the approximate length of indel edits (...) can be somewhat customized with different GEENs and by manipulating the expression of key NHEJ genes. Structural data suggest that binding of GEENs to DNA may interfere with binding of key components of DNA repair complexes, favoring either classical‐ or alternative‐NHEJ. The hypotheses have some limitations, but if validated, will enable scientists to better control indel makeup, holding promise for basic science and clinical applications of gene editing.

ObjectivesHostile attribution bias is reportedly common from non-clinical population to those with serious mental illness, such as schizophrenia, and is known to be closely related to theory of mind. This study aimed to investigate whether ToM skills mediate the relationship among neurocognitive ability, personality traits, and attribution bias.MethodsA total of 198 non-clinical youths were recruited. To assess their neurocognitive ability and ToM skills, the participants were asked to complete Raven’s Standard Progressive Matrices and the Korean version of the Reading the (...) Mind in Eyes Test. To determine their personality traits, the Eysenck Personality Questionnaire and interpersonal reactivity index were used. To evaluate hostile attribution bias, the Ambiguous Intentions Hostility Questionnaire was administered. Path analysis and bias-corrected percentile bootstrap methods were used to estimate model fit and the parameters of the mediating effects.ResultsBased on model comparison, the best model characterized two direct pathways from psychoticism and the K-RMET to hostility attribution bias and three indirect pathways, wherein SPM, perspective taking, and psychoticism influenced hostile attribution bias through K-RMET. The final model fit indices were good [x2/df = 1.126; comparative fit index = 0.996; root mean square error of approximation = 0.026; standard root mean square residual = 0.026 and Akaike information criterion = 28.251] and the K-RMET fully mediated the association between SPM, perspective taking, psychoticism, and hostile attribution bias.ConclusionThe main findings suggested that ToM skills, such as the RMET, play an important role in explaining the relationship among neurocognitive ability, personality traits, and hostile attribution bias. ToM skills and a remediation strategy may need to be developed to balance the enhanced hostility bias that underlies the paranoia. (shrink)

Many transnational corporations and international organizations have embraced corporate social responsibility to address criticisms of working and environmental conditions at subcontractors' factories. While CSR 'codes of conduct' are easy to draft, supplier compliance has been elusive. Even third-party monitoring has proven an incomplete solution. This article proposes that an alteration in the supply chain's governance, from an arms-length market model to a collaborative partnership, often will be necessary to effectuate CSR. The market model forces contractors to focus on price and (...) delivery as they compete for the lead firm's business, rendering CSR observance secondary, at best. A collaborative partnership where the lead firm gives select suppliers secure product orders and other benefits removes disincentives and adds incentives for CSR compliance. In time, the suppliers' CSR habit should shift their business philosophy toward pursuing CSR as an end in itself, regardless of buyer incentives and monitoring. This article examines these hypotheses in the context of the athletic footwear sector with Nike, Inc. and its suppliers as the specific case study. The data collected and conclusions reached offer strategies for advancing CSR beyond the superficial and often ineffectual 'code of conduct' stage. (shrink)

This study examined influential factors of newspaper corporation social responsibility and evaluated corporate social responsibility using a newspaper corporate social responsibility index. Results of this study, which was conducted by survey, showed that arbitrative, essential, and cultural activities were influential factors comprised of newspaper corporate social responsibility. In addition, the findings indicated that higher corporate social responsibility index was not accompanied by Korean newspaper corporations with larger circulations.

This article attempts to fill a gap in International Relations literature on East Asian security. ‘East Asia’ appears to be mostly an indeterminate conceptual construct, allowing scholars to look selectively at those aspects and areas that could justify their security thesis, albeit security dynamics in the region are all too difficult to comprehend and predict. This problem has been frequently pointed out in IR literature, but its methodological implications and suggestions have neither been appropriately illuminated nor been systematically offered, and (...) the main solution commonly found in the literature was the tautological one of ‘better defining’ the region. As an alternative, this article suggests that one needs to tighten geographical focus and differentiate the subjects of analysis. When it comes to the study of East Asian security, one needs to aim to develop specific and differentiated generalizations as opposed to generalizations of a broad character. To showcase the fact that research outcomes can be more determinate when the target of analysis is more focused and specified, this article takes Northeast Asian security as an example and challenges the so-called ‘peaceful East Asia’ thesis, one of the mainstream perspectives on East Asian security. This article ultimately argues that while apprehending East Asian security dynamics through delimiting the scope of analysis and circumscribing the subjects of investigation is often deemed to be a modest enterprise―in particular, in terms of generalizability―the merits are substantial: research outcomes will be able not only to give us a truer mapping of the real world, but also bring us closer to building knowledge which satisfies the scientific criterion of ‘falsifiability.’Export citation Request permission.

The zone of proximal development (ZPD) is defined as an overarching concept that integrates the main tenets of Vygotsky’s theory of human development. The conceptualization of the ZPD begins with its social, cultural, and historical context and traces its development as a spatial and temporal metaphor that reflects the sociogenetic root of all human mental functioning. Beyond the explication of sociogenesis, the ZPD is reconceptualized to include the notions of voice and dialogicality. The insights gained from the fields of semiotics (...) and discourse studies allow a broader understanding of the ZPD by bringing to light participant structures and institutional and historical forces that may not have been included in the dominant interpretations of the ZPD.

The study reviewed 20 currently-available structured ethical decision-making models and developed an integrated model consisting of six steps with useful questions and tools that help better performance each step: (1) the identification of an ethical problem; (2) the collection of additional information to identify the problem and develop solutions; (3) the development of alternatives for analysis and comparison; (4) the selection of the best alternatives and justification; (5) the development of diverse, practical ways to implement ethical decisions and actions; and (...) (6) the evaluation of effects and development of strategies to prevent a similar occurrence. From a pilot-test of the model, nursing students reported positive experiences, including being satisfied with having access to a comprehensive review process of the ethical aspects of decision making and becoming more confident in their decisions. There is a need for the model to be further tested and refined in both the educational and practical environments. (shrink)

Green consumers are those who seek to fulfill economic responsibility with their choices of environment-friendly products. Previous research found that it is not easy to identify green consumers by using traditional demographic or psychographic measurements due to the instability of moral attitude and actual behavior. The frontal theta brain waves of 19 right-handed respondents were recorded and analyzed in a choice task between an environment-friendly (green) product and a conventional product. Product information, which was provided to the respondents, included written (...) descriptions as well as the price of each product without visual depiction. Based on the respondents’ choice, they were classified into two groups: green (GR) consumers who chose an environment-friendly product option and non-green (Non-GR) consumers who chose the option of a conventional product. While processing the green product message, we discovered that frontal theta activations were significantly higher among GR consumers than Non-GR consumers. On the contrary, the frontal theta waves of GR consumers were not differentiated from Non-GR consumers while processing the price information. Therefore, theta activations in the frontal area may potentially be a unique neural indicator of GR consumers’ cognitive engagement with environment-friendly product messages. (shrink)

In empiricism, there are only two answers for a question: black or white. Yet, subjective meanings of human behaviours and responses toward health and illness cannot be simply explained with black and white. Gray zones are needed because they are characterized by complexity and require a contextual understanding. In this paper, we present and suggest fuzzy logic as an example of theoretical bases that help transcend the conflicts between objectivity and subjectivity, respect gray zones between black and white answers for (...) questions, and provide a contextual understanding of complex nursing phenomenon. A historical review of fuzzy logic is followed by a definition of fuzzy logic. Then, fuzzy logic is discussed in terms of its compatibility with nursing epistemological views and philosophical thoughts. Fuzzy logic agrees with three categories of epistemological views of nursing, including correspondence, coherence and pragmatism. Fuzzy logic also agrees with four major philosophical thoughts in nursing, including postempiricism, pragmatism, feminism, and postmodernism. Based on the discussion, we propose that fuzzy logic be further explored, used and developed in research and practice in the nursing areas/situations/phenomena that are characterized by complexity, ambiguousness, and vagueness.

Purpose: The purpose of this study was to verify the long-term effect of adverse childhood experiences, school disengagement, and the reasons for leaving school on adolescent delinquency while adjusting for sex.Methods: Data were collected from 663 teenagers [male 368, female 295; mean age = 16.81 ; age range = 13–19 years] through a Longitudinal Survey and Support Plan for Dropouts.Results: Multivariate latent growth modeling demonstrated that ACEs and school disengagement are positively associated with delinquency and the mediating effect of school (...) disengagement on association between ACEs and delinquency was verified. Teenagers who quit school for personal reasons reported fewer instances of delinquent behavior than adolescents who left because of school reasons.Conclusion: This study suggests that researchers and teachers need to consider ACEs and school disengagement as a warning index for delinquency with school dropout. In addition, the reason for leaving school should be considered to clarify the effect of school dropout on delinquency in adolescents who dropout. (shrink)

In my dissertation I examine Plato's ontology. As is well-known, Plato accepts the existence of two different kinds of entities: sensible particulars, such as Socrates, and Forms, such as the Form of Beauty. Moreover, according to the standard understanding of Plato, he thinks that there are entities of no other kind. I argue that this is an incorrect understanding. Specifically, I argue that Plato assumes the existence of entities of a third kind in the Phaedo. ;The dissertation has developed from (...) my attempts to clarify Plato's conception of the human soul. By examining the Phaedo, the dialogue in which Plato gives his most elaborate discussions of the ontological status of the soul while attempting to prove its immortality, I conclude that Plato conceives the soul as an entity whose ontological status is intermediate between those of Forms and sensible particulars: It has some of the features used to characterize forms and some of the contrary features used to characterize sensible particulars. ;In the dissertation, I first examine the features characterizing forms and those characterizing sensible particulars. Second, I discuss the first group of intermediate entities, the opposites in us, and argue that they are intermediate in the sense in question. Third, I discuss the group of entities that I call the occupiers, such as fire or the number three, and show that they are also seen as intermediates. Finally, I discuss the human soul as an intermediate entity belonging to this second group of intermediates, and show that the Final Argument for the immortality of the soul in the Phaedo can be best understood with reference to the framework including the intermediates as well as forms and sensible particulars.

Integrating the categorization-elaboration model (CEM), resource complementarity, and human capital perspectives, we investigate whether the founder CEO’s human capital resources can influence the effect of workforce gender diversity, an untapped strategic resource, on venture firm performance. Our main focus lies on knowledge- and technology-intensive venture firms, and we propose that both workforce gender diversity and the CEO’s human capital resources jointly influence venture firm performance. We identify the specific functional impacts of the founder CEO's human capital, encompassing entrepreneurial experience, human (...) resource (HR) management experience, and same-industry experience. Analyzing 1413 venture firms utilizing multilevel analysis (random coefficient modeling), we find that gender diversity does not significantly affect venture firm performance. Nevertheless, the founder CEO’s entrepreneurial experience exerts a positive impact on the interplay between gender diversity and venture firm performance. These findings underscore the strategic role of the founder CEO’s human capital resources in moderating the effects of gender diversity, making significant contributions to the diversity and strategic human capital resource literature.

In this Article, Professor Suk defends the moral legitimacy of liberal states’ legal protection of minority languages. Many opponents of minority language protection have argued or assumed that legal intervention denies individuals the right to choose the majority language and the economic opportunities often attached to the dominant language. This Article argues that such arguments overlook another category of goods that are necessary to individual autonomy: relational resources. Individuals have an interest in maintaining their ancestral languages because doing so is (...) essential to maintaining one’s relationship to one’s family and community. The relational interest cannot easily be compared with economic opportunities, because these two dimensions of autonomy are incommensurable. As a result, a liberal state should avoid forcing its citizens to choose between these incommensurable goods. By adopting policies that protect minority languages, while also ensuring individuals’ access to economic and political participation in the majority language, a liberal state can manage and balance the conflict between these important competing aspects of autonomy.

Fashion is an important source for shedding light on modern aesthetic experience. Not only does fashion represent concrete aesthetic quality that reveals the spirit of the times, but it also epitomizes the social relations in liaison with the aesthetic taste of the times. This essay discusses the relationship between Georg Simmel’s sociological aesthetics and Hegel’s dialectics, demonstrates fashion as a domain in which subject-object relations are operative, and shows how fashion hypostatizes the dialectical relations between mind and body and between (...) the individual and the collective while connecting subject and object.

With the advancement of medical technology, various life-sustaining treatments are available at the end of life. Older adults should be encouraged to establish their end-of-life treatment preferences (ELTP) while they are physically and mentally able to do so. The purpose of this study was to explore ELTP among older adults and to compare those preferences in a subset of individuals who had reported their ELTP in a survey completed the previous year. This was a descriptive study of 191 older adults (...) living in a continuing care retirement community. Approximately half of the participants did not want cardiopulmonary resuscitation, to be put on a respirator, or to receive dialysis. The findings in this study suggest that many older adults do not want aggressive interventions at the end of life, but choose rather those measures that will keep them comfortable. Moreover, treatment choices may change over time. Health care providers should initiate discussions about ELTP at regular intervals (yearly) to assist older adults in dictating their end-of-life care. (shrink)

In our study, we examine the association between hedge fund activism and a target firm’s corporate social responsibility (CSR) activities and whether activists can promote socially responsible investments while upholding shareholders’ interests. Using different matched samples, we find a strong positive association between the target firm’s CSR in the year before it is targeted by activists and its probability of being targeted by a hedge fund. Classifying hedge fund activists into socially and non-socially responsible funds based on their objectives, we (...) find that both give similar level of consideration to a firm’s CSR activities when initiating campaigns. Similar to DesJardine and Durand (DesJardine and Durand, Strategic Management Journal 41:1054–1082, 2020), we demonstrate that hedge funds have, on average, a negative impact on target firms’ CSR in the years following the initial investments. Complementary to DesJardine and Durand (DesJardine and Durand, Strategic Management Journal 41:1054–1082, 2020), we compare the two types of hedge funds and find an asymmetric effect of the hedge funds’ campaigns. Socially responsible hedge fund campaigns are associated with a large _increase_ in their target’s CSR, whereas non-socially responsible hedge funds _decrease_ this measure in their target. Finally, we find that target firms exhibit a long-term improvement in future stock returns and profitability. These findings provide evidence that certain types of activists, such as socially responsible funds, promote both _stakeholder_ and _shareholders’_ long-term interests. (shrink)

This article presents a phenomenology of artistic painting as an anticipatory process. I propose that the artist seeks to establish a state of equilibrium in a model of self-awareness expressed and represented in a self-constituted physical artefact intended to communicate to others, not representationally but affectively. ‘Neural painting’ is an arts-based research method employing a simple computational model of human aesthetic discrimination to study the creative realization of the artistic image. I use this method to explore the relationship of self (...) and ‘other’ in computationally mediated self-portraiture. I develop an image in an exchange with a neural network by reflecting on its output and inputting autographic modifications to those images, blending visceral gesture with the ‘black box’ of artificial intelligence. Through this deeply personalized and perhaps agonistic interchange between organic self and algorithmic reflection, I seek to expose the tacit mediation implicit in the technical artefact, opening an understanding of the existential relations between natural systems (the artist) and technical entities positioned as collaborators in an anticipatory aesthetics.

Computerized relaxation training has been suggested as an effective and easily accessible intervention for individuals with psychological distress. To better elucidate the neural mechanism that underpins the effects of relaxation training, we investigated whether a 10-session computerized relaxation training program changed prefrontal gamma-aminobutyric acid levels and cerebral blood flow in women with psychological distress. We specifically focused on women since they were reported to be more vulnerable to develop stress-related disorders than men. Nineteen women with psychological distress but without a (...) diagnosis of psychiatric disorders received the 10-day computerized relaxation training program that consisted of 30-min cognitive-relaxation training and 10-min breathing-relaxation training per day. At baseline and post-intervention, perceived stress levels, anxiety, fatigue, and sleep quality were assessed by self-report questionnaires. Brain magnetic resonance spectroscopy and arterial spin labeling scans were also performed before and after the intervention to evaluate GABA levels and relative CBF in the prefrontal region. Levels of perceived stress, anxiety, fatigue, and sleep quality improved following 10 sessions of computerized relaxation training, resulting in a significant relief in composite scores of stress-related symptoms. The prefrontal GABA levels decreased, while relative CBF increased after the intervention. In addition, a greater increase in relative prefrontal CBF was associated with better composite scores of stress-related symptoms following the intervention. The current findings suggest that computerized relaxation training may improve stress-related symptoms through modulating the prefrontal GABA levels and CBF in women with psychological distress.

Most of the world’s constitutions contain clauses guaranteeing sex equality, and many also extend the special protection of the state to mothers. The constitutional protection of motherhood is undertheorized and neglected in global constitutional discourse, perhaps because jurisdictions like the United States view the special protection of women as contrary to gender equality. This Essay explores the feminist meanings and possibilities of constitutional motherhood clauses, by focusing on Germany, where they originated in 1919. While motherhood clauses have had complex relationships (...) with a range of feminist agendas, they solidified the notion that social reproduction was a subject for constitutional lawmaking. Addressing twenty-first century gender inequalities requires a more robust engagement of women’s disproportionate burdens in social reproduction. Having opened up a constitutional discourse around the challenges of social reproduction, motherhood clauses and gender equality guarantees can drive the search for new solutions. (shrink)

Many clinical and psychological constructs are conceptualized to have multivariate higher-order constructs that give rise to multidimensional lower-order traits. Although recent measurement models and computing algorithms can accommodate item response data with a higher-order structure, there are few measurement models and computing techniques that can be employed in the context of complex research synthesis, such as meta-analysis of individual participant data or integrative data analysis. The current study was aimed at modeling complex item responses that can arise when underlying domain-specific, (...) lower-order traits are hierarchically related to multiple higher-order traits for individual participant data from multiple studies. We formulated a multi-group, multivariate higher-order item response theory (HO-IRT) model from a Bayesian perspective and developed a new Markov chain Monte Carlo (MCMC) algorithm to simultaneously estimate the (a) structural parameters of the first- and second-order latent traits across multiple groups and (b) item parameters of the model. Results from a simulation study support the feasibility of the MCMC algorithm. From the analysis of real data, we found that a bivariate HO-IRT model with different correlation/covariance structures for different studies fit the data best, compared to a univariate HO-IRT model or other alternate models with unreasonable assumptions (i.e., the same means and covariances across studies). Although more work is needed to further develop the method and to disseminate it, the multi-group multivariate HO-IRT model holds promise to derive a common metric for individual participant data from multiple studies in research synthesis studies for robust inference and for new discoveries.

To effectively train ethical decision-making of nursing students, a case-based computer program was developed using Flash animation. Seven ethical cases collected from practicing registered nurses’ actual clinical experiences and a six-step Integrated Ethical Decision-Making Model developed by the author were employed in the program. In total, 251 undergraduate students from three nursing schools used the program in their nursing ethics course. The usability of the program and its usefulness in improving 11 abilities needed in ethical decision-making were measured; it scored (...) higher than 4 on a 5-point scale. Of the students, 82% recommended the program as a valuable complementary tool in the teaching of a nursing ethics course. A variety of encouraging and positive experiences were reported by the students. The computer program is likely to be usefully practical in the training of abstract skills to nursing students, though certain challenges remain, such as the precise understanding of cognitive or affective responses to ethical issues.
