The purpose of this study is to examine whether corporate social responsibility activities perceived by consumers affect brand trust and corporate sustainability management. In other words, this study tried to examine whether the compatibility and authenticity of CSR influences brand trust, thereby affecting CSM including economic viability, environmental soundness, and social responsibility. To measure this, an empirical analysis was conducted on 479 consumers who had experience purchasing products from cosmetic companies that are carrying out CSR. As a result of the (...) analysis, it was found that the compatibility and authenticity of CSR have a positive effect on brand trust. Also, it was found that brand trust had a positive effect on social responsibility among the sub-concepts of CSM, but did not affect economic viability and environmental soundness. The results of this study are expected to provide strategic implications for social responsibility performance and brand trust building necessary for cosmetics companies to grow continuously.

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)

We analyze the use of Silbot – a “dementia-prevention robot” – in a regional health center in South Korea. From our on-site observation of the Silbot classes, we claim that the efficacy of the robot class relies heavily on the “strained collaboration” between the human instructor and the robot. “Strained collaboration” refers to the ways in which the instructor works with the robot, attempting to compensate for the robot’s functional limitation and social awkwardness. In bringing Silbot into the classroom setting, (...) the instructor employs characteristic verbal tones, bodily movements, and other pedagogical tactics. The instructor even talks over the robot, downplaying its interactional capacity. We conclude that any success of such robot programs requires a deeper understanding of the spatial and human context of robot use, including the role of human operators or mediators and also that this understanding should be reflected in the design, implementation, and evaluation of robot programs.

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. (shrink)

Three visual habituation studies using abstract animations tested the claim that infants’ attachment behavior in the Strange Situation procedure corresponds to their expectations about caregiver–infant interactions. Three unique patterns of expectations were revealed. Securely attached infants expected infants to seek comfort from caregivers and expected caregivers to provide comfort. Insecure-resistant infants not only expected infants to seek comfort from caregivers but also expected caregivers to withhold comfort. Insecure-avoidant infants expected infants to avoid seeking comfort from caregivers and expected caregivers to (...) withhold comfort. These data support Bowlby’s (1958) original claims—that infants form internal working models of attachment that are expressed in infants’ own behavior. (shrink)

ObjectiveThis pilot study aimed to evaluate the efficacy of a digital cognitive behavioral therapy in patients with cancer experiencing sleep problems.MethodsA total of 57 participants aged 25–65 years were randomly assigned to three groups—21 participants to a dCBT program, 20 participants to an app-based attentional control program, and 16 participants to a waitlist control group—and evaluated offline before and after the program completion. Of the 57 participants, there were a total of 45 study completers, 15 participants in each group. The (...) dependent variables were sleep quality scores, measured by the Pittsburgh Sleep Quality Index and health-related quality of life scores, measured using the Short-Form 36, and attentional bias scores from a dot-probe computer task.ResultsFor both the intention-to-treat and study-completers analyses, a significant increase supported by a large effect size was found in the quality of sleep score of the HARUToday Sleep group compared to both the app-based attentional control and the waitlist control group. However, no significant changes were found in the quality of life and attentional bias scores.ConclusionOur results suggest that the HARUToday Sleep app has the potential to serve as an intervention module to enhance the sleep quality of patients with cancer experiencing sleep problems.

This study investigated inverse preference effects in L2 structural priming of English relative clauses and their potential influences on subsequent learning of target structures. One hundred fourteen Chinese learners of English at a low-to-intermediate proficiency level participated in a structural priming experiment with a pretest-posttest design. The experimental group underwent a priming task in which they orally produced syntactic structures immediately after viewing English object or passive relative clauses as primes, whereas the control group only read sentences unrelated to English (...) relative clauses. A grammaticality judgment task and a sentence completion task were used to measure the inverse preference effect and its subsequent effects on L2 learning. The results showed the presence of structural priming and inverse preference effects in immediate production, which extended to subsequent learning of L2. In subsequent grammaticality judgments and production, L2 learners performed better with English object relative clauses than with English passive relative clauses in comparison with the pretest. The results are discussed in terms of the structural frequency in both L1 and L2 as well as the implicit learning mechanisms of structural priming. (shrink)

La subcultura sadomasochistica della “dominazione femminile” (femdom) ha dato vita a una modalità rilevante di carnalità digitale, prevalente nelle interfacce dei nuovi media e capace al contempo di radicalizzarne l’interattività. La relazione dell’uomo sottomesso con la donna dominante non è mai semplice in questo caso: non meramente pornografica, bensì sintomatica di fenomeni complessi. Essi riguardano il potere e la società, i media e la vita che danno forma alla nostra epoca tecno-libidinale. L’articolo getta luce sulle implicazioni sessuali, psicologiche, psicoanalitiche e (...) socio-etiche di tale relazione, delineando e ricontestualizzando le teorie su masochismo, abiezione, biopolitica, nichilismo e così via. Pieno di paradossi, il femdom incarna un governo, formalmente strutturato, della sensazione e della determinazione: una legge eccezionale oltre la legge normale, secondo cui la sottomissione a un sovrano sessuale conduce contemporaneamente alla autoprivazione e al recupero della libertà dello schiavo. Il suo desiderio frustrato di un oggetto irraggiungibile si orienta allora verso una pulsione di tipo lacaniano: la soddisfazione istantanea di circolare intorno al vuoto, come se ci si “avvicinasse” continuamente, senza fine, così com’è esemplificato nel loop digitale delle immagini GIF. Più precisamente, desiderio e deriva si confondono, al punto di essere indistinguibili, nella disintegrazione del Simbolico e del Reale, del privato e del pubblico, che caratterizza la cultura dell’assuefazione autodistruttiva, tipica dell’edonismo capitalistico. In tale contesto il mondo di sogno del femdom si rivela essere una rete permeabile di numerose comunità fondatrici di forme di vita di dominatrici e sottomessi: un cielo interattivo, capace di automodularsi, di desiderio-impulso senza una fine, senza un fuori, senza un nirvana.

Sleep quality, personality, and cognitive load potentially increase second language writing (SLW) anxiety and subsequently affect SLW achievement. This study investigates the predictions of sleep quality, personality (social inhibition/ negative affectivity), and cognitive load (content/ computer) toward SLW anxiety and achievement in a computer-based test. Participants included 172 voluntary undergraduates majoring in English as foreign language. SLW anxiety in a computer-based test, sleep disturbance, personality and cognitive load was assessed with the SLW Anxiety Inventory, Pittsburg Sleep Quality Index, Type-D Personality, (...) and cognitive load questionnaires. A structural equation modeling approach was applied to examine the interdependence among the observed variables. An adequate-fit SLW anxiety model was built (X2 = 6.37,df = 6,p = 0.383,NFI = 0.97,CFI = 1.00,RMSEA = 0.02; R-squared multiple correlations: SLW anxiety in a computer-based test = 0.19, computer-based SLW achievement = 0.07). The structural model showed that sleep disturbance (+0.17), social inhibition personality (+0.31), and computer-induced cognitive load (+0.16) were significant predictors of SLW anxiety in a computer-based test. Subsequently, SLW anxiety in a computer-based test (−0.16) and computer-induced cognitive load (−0.16) were significant negative predictors of computer-based SLW achievement. (shrink)

In light of the dramatic growth of Chinese learners worldwide and a need for cross-linguistic research on Chinese literacy development, this study drew upon theories of visual complexity effect (Su & Samuels, 2010) and dual-coding processing (Sadoski & Paivio, 2013) and investigated a) the effects of character properties (i.e., visual complexity and radical presence) on character acquisition and b) the relationship between individual learner differences in radical awareness and character acquisition. Participants included adolescent English-speaking beginning learners of Chinese in the (...) U.S. Following Kuo et al. (2014), a novel character acquisition task was used to investigate the process of acquiring the meaning of new characters. Results showed that a) characters with radicals and with less visual complexity were easier to acquire than characters without radicals and with greater visual complexity; and b) individual differences in radical awareness were associated with the acquisition of all types of characters, but the association was more pronounced with the acquisition of characters with radicals. Theoretical and practical implications of the findings were discussed. (shrink)

This article aims to explore the connection between classical learning and study of governing in Jeong Yak-yong’s thought, by considering ‘achievement investigation 考績’ in Old Lessons of Book of Documents 尙書古訓–his typical work on classical learning, and Testaments on Study of Governing 經世遺表–his representative work of study of governing. In Old lessons of Book of Documents, Jeong Yak-yong analyzes the investigation of officials’ achievements in the interpretations on political activities and thoughts of Yao 堯, Shun 舜, Yu 禹, (...) Gao Yao 皐陶. He points that the achievement investigation is ‘great way’ of Yao-Shun’s politics. This investigation is conducted every three years, and after three times the reward and punishment, the promotion and demotion are carried out. This investigation is applied to all officials in the bureaucracy. The investigation of officials’ achievements is conducted as follows: the mandarin comes before the King and directly reports on his own achievements. After that the King embarks an inspection tour to areas to verify those reports. To Testaments on Study of Governing, the achievement investigation is built into one of the plans for bureaucratic reform. Jeong Yak-yong, based on the achievement investigation recorded in Book of Documents 書經 and Rites of Zhou 周禮, thinks that in the contemporary Joseon, the achievement investigation should be conducted every one year and after three times the reward or promotion should be carried out. In his thought, the achievement investigation must be applied to all officials, not only to the low-ranking ones as the current regulation. Jeong Yak-yong proposes investigation methods applied to central and local officials. In the investigation of local officials’ achievements, Jeong Yak-yong pays a special attention to the investigation of Su-ryeong 守令–the leader of each local area. He proposes the so-called “9 guiding principles” with 54 articles to investigate Su-ryeongs’ achievements. He also states that it is necessary to define the levels in considering the achievements of officials, and the fixed number of officials in each level. After three years (means three times of investigation), each Su-ryeong must return to the capital to directly report his achievements before the King, and after that the court send inspectors to the locality to secretly investigate those reports. Through the changes and development of the achievement investigation from unsystematic arguments (in Old lessons of Book of Documents) to a complete reform plan (in Testaments on Study of Governing), it can be seen the close connection between the classical learning and the study of governing in Jeong Yak-yong’s thought. His classical learning and study of governing themselves are different from ones in Neo-Confucians: his classical learning pays attention to the social ruling issues, and his study of governing itself is comprehensive social reform projects. That practical classical learning provides ideal models – social standards and ruling ways in Yao-Shun era - for that reformist study of governing. And it also provides important theories on human nature, cultivation, politics etc. for the study of governing so that it has a solid ground for the reformist arguments. Moreover, Jeong Yak-yong’s study of governing also relies on the reality (the practical situations) to develop reform plans, thus on one hand, it contains new, practical and rational features, and on the other hand, it makes the classical learning become more realistic.

What signals do firms in emerging economies send to stakeholders when they adopt corporate social responsibility practices? We argue that in emerging economies, firms that adopt CSR practices positively signal investors that their firms have superior capabilities for filling institutional voids. From an institution-based view, we hypothesize that the institutional environment moderates the signaling effect of CSR on a firm’s financial performance. Based on a sample of firms from ten Asian emerging economies, we find a positive relationship between CSR practices (...) and financial performance. This positive relationship is stronger in the less developed capital market than in the more developed one. The financial benefits of CSR practices are also more salient in the low information diffusion market than in the high one. We emphasize that signaling theory and the institution-based view can jointly contribute to the CSR literature. (shrink)

The purpose of this study was to explore the motivational structures of external whistleblowers involved in the decision to blow the whistle by applying MEC theory and the laddering technique. Using both soft and hard laddering methods, data were collected from 37 Korean external whistleblowers. Results revealed that the means-end chain of external whistleblowers was the hierarchical linkage among two concrete attributes, two functional consequences, and one terminal value. The extant whistleblowing literature has either made assumptions about whistleblowers’ motivations when (...) developing models or has drawn indirect inferences from measures of other variables. Our study is the first with an explicit and empirical focus on whistleblowers’ motivations. The findings provide evidence of the motivational structures of external whistleblowers that consist of a set of complex paths linked by multi-layered motivators. This research will be helpful in designing and reviewing whistleblowing programs for organizations, regulatory agencies, and journalists. (shrink)

This study explores the linear logic between consumer ethical beliefs (CEBs) and consumer unethical behavior (CUB) in a Chinese context. A relational view helps fill the belief–behavior gap by exploring the moderating role of relationship quality in reducing CUBs. Specifically, when consumers are more receptive to a set of actions that may be deemed inappropriate by moral principles, they are more likely to engage in unethical behaviors. However, when consumers perceive their misconduct as possibly damaging to the relationship developed with (...) the seller, they tend to refrain from unethical behaviors. CEBs and relationship quality also combine to affect unethical behaviors. Although consumers find the misconduct acceptable according to their ethical beliefs, they become less likely to conduct the behavior if they have a close relationship with the seller. The results contribute to a better understanding of the simplistic logic that connects CEBs and their unethical behaviors and shed light on how close relationships with consumers help contain CUBs.

Although the prevalence of facial recognition-based COVID-19 surveillance tools and techniques, China does not have a facial recognition law to protect its residents’ facial data. Oftentimes, neither the public nor the government knows where people’s facial images are stored, how they have been used, who might use or misuse them, and to what extent. This reality is alarming, particularly factoring in the wide range of unintended consequences already caused by good-intentioned measures and mandates amid the pandemic. Biometric data are matters (...) of personal rights and national security. In light of worrisome technologies such as deep-fake pornography, the protection of biometric data is also central to the protection of the dignity of the citizens and the government, if not the industry as well. This paper discusses the urgent need for the Chinese government to establish rigorous and timely facial recognition laws to protect the public’s privacy, security, and dignity amid COVID-19 and beyond.

This paper argues that Foucault’s genealogy of racism deserves appreciation due to the highly original concept of racism as biopolitical government. Modern racism, according to Foucault, is not merely an irrational prejudice, a form of socio-political discrimination, or an ideological motive in a political doctrine; rather, it is a form of government that is designed to manage a population. The paper seeks to advance this argument by reconstructing Foucault’s unfinished project of a genealogy of racism. Initially, the paper situates the (...) genealogy of racism within the context of Foucault’s work. It belongs to a period of transition between the mature and the late part of Foucault’s work, more specifically a period of transition from discipline to governmentality. The paper proceeds by reading closely key passages from the 1976 lectures at Collège de France in which Foucault proposes to rethink racism as a form of biopolitical government. While Foucault’s genealogy of racism remains an incomplete project, lacking for example any substantial treatment of European colonialism, the paper proposes to expand the Foucauldian analysis by linking it to the pan-German discourse between 1890 and 1914. Finally, the paper reflects on some of the implications of the Foucauldian analysis, in particular attempts to understand and counter contemporary forms of racism. Foucault’s genealogy of racism, in short, shows us the constructedness of our racialized world and challenges us to develop new and more effective strategies to change it. (shrink)

ZUSAMMENFASSUNG Die vorliegende Arbeit unternimmt den Versuch, zu erklären, was Heidegger mit dem Ausdruck “die Verwandlung des Biographischen im Gedichteten” bei seiner Erläuterung der Hölderlinschen Hymne Andenken meint. Viele Literaturwissenschaftler interessieren sich für das Entstehungsdatum der Hymne und die damaligen Erlebnisse Hölderlins, um daraus die Hymne zu interpretieren. Im Vergleich mit ihnen richtet Heidegger wenig sein Augenmerk darauf, weil er glaubt, dass das Biographische des Dichters unmittelbar nichts mit dem Inhalt des Gedichtes zu tun hat. Bei der Dichtung geschieht Heidegger (...) zufolge die Verwandlung des Biographischen im Gedichteten. Demnach untersucht die vorliegende Arbeit das Phänomen des Dichtens. Dazu wird Heideggers Erläuterung der Hymne Wie wenn am Feiertage... herangezogen, die er als die “reinste Dichtung des Wesens der Dichtung” ansieht. Danach wird das Gedicht Andenken im Hinblick auf die “Schiffer” betrachtet, die Heidegger die “kommenden Dichter Germaniens” nennt. Diese Betrachtung dient dazu, die Verwandlung, die im Dichten geschieht, zu erläutern. ABSTRACT I attempt to explain what Heidegger means by the expression “the transformation of the biographical data in the poem” in his elucidation of the Hölderlin’s hymn Remembrance. Many scholars of German literature are interested in the date of the hymn and in Hölderlin’s experience at that date, in order to interpret the hymn. In contrast to them, Heidegger does not concern himself with the date, because he believes that the poet’s biographical data has nothing to do with the content of the poem directly. According to Heidegger, the transformation of the biographical data in the poem takes place through a process of poeticizing. Therefore, I investigate this process as the nature of the poetry. For this investigation, I refer to Heidegger’s elucidation of the hymn As When on Holiday..., which he regards as the “purest poem on the essence of poetry”. Afterwards, I interpret the hymn Remembrance in view of the “mariners”, which Heidegger calls “Germania’s coming poets”. This interpretation serves to help us understand the transformation that occurs in the process of poeticizing. (shrink)
