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.

The dominant position of e-commerce is especially being articulated in the retailing industry once again due to several constraints that the world faces in the COVID-19 pandemic era. In this regard, this study explores the significant role of trust transfer and the moderating effect of consumers’ neurotic traits in the framework of trust-satisfaction-repurchase intention in the e-commerce context based on a survey with 406 Korean e-commerce consumers. Moreover, a prediction-oriented segmentation technique combined with structural equation models was utilized to reveal (...) consumers’ probable hidden heterogeneous characteristics. The outcomes of the global model SEM analysis indicate that offline-online trust transference occurs in e-commerce, and the conveyed trust significantly influences satisfaction and consumers’ repeat purchase intention through satisfaction. Neuroticism also has significant positive effects on trust transfer in the global model. However, results in three subgroups generated by POS show heterogeneous characteristics that considerably differed from the global model test results. The implications from this study will be beneficial to field practitioners in the e-commerce industry in addressing the importance of trust transfer, negative neurotic traits as well as heterogeneous aspects of consumers.

Turnover is an important career decision that influences both individual employees and their organizations. While human resource management scholars have long sought to understand critical components of a workplace where employees want to stay, ethics has become a primary factor of interest in public sector turnover intention studies only in recent years. This article contributes to this growing line of research by investigating if and how ethical work environment influences public employees’ turnover intentions, and how this relationship is moderated by (...) an employee’s position of power measured by supervisory status. The findings suggest that ethical work environment is a critical determinant of public employees’ turnover intentions and that supervisory status can moderate this relationship. (shrink)

Cross-classified random effects models have been developed for appropriately analyzing data with a cross-classified structure. Despite its flexibility and the prevalence of cross-classified data in social and behavioral research, CCREMs have been under-utilized in applied research. In this article, we present CCREMs as a general and flexible modeling framework, and present a wide range of existing models designed for different purposes as special instances of CCREMs. We also introduce several less well-known applications of CCREMs. The flexibility of CCREMs allows these (...) models to be easily extended to address substantive questions. We use the free R package PLmixed to illustrate the estimation of these models, and show how the general language of the CCREM framework can be translated into specific modeling contexts. (shrink)

Obstructive sleep apnea severely impacts sleep and has long-term health consequences. Treating sleep apnea with continuous positive airway pressure not only relieves obstructed breathing, but also improves sleep. CPAP improves sleep by reducing apnea-induced awakenings. CPAP may also improve sleep by enhancing features of sleep architecture assessed with electroencephalography that maximize sleep depth and neuronal homeostasis, such as the slow oscillation and spindle EEG activity, and by reducing neurophysiological arousal during sleep. We examined cross-sectional differences in quantitative EEG characteristics of (...) sleep, assessed with power spectral analysis, in 29 adults with type 2 diabetes treated with CPAP and 24 adults undergoing SHAM CPAP treatment. We then examined changes in spectral characteristics of sleep as the SHAM group crossed over to active CPAP treatment. Polysomnography from the CPAP titration night was used for the current analyses. Analyses focused on EEG frequencies associated with sleep maintenance and arousal. These included the slow oscillation, sigma activity, and beta activity in F3, F4, C3, and C4 EEG channels. Whole night non-rapid eye movement sleep and the first period of NREM spectral activity were examined. Age and sex were included as covariates. There were no group differences between CPAP and SHAM in spectral characteristics of sleep architecture. However, SHAM cross-over to active CPAP was associated with an increase in relative 12–16 Hz sigma activity across the whole night and a decrease in average beta activity across the whole night. Relative slow oscillation power within the first NREM period decreased with CPAP, particularly for frontal channels. Sigma and beta activity effects did not differ by channel. These findings suggest that CPAP may preferentially enhance spindle activity and mitigate neurophysiological arousal. These findings inform the neurophysiological mechanisms of improved sleep with CPAP and the utility of quantitative EEG measures of sleep as a treatment probe of improvements in neurological and physical health with CPAP.

Government-sponsored school lunch programs have garnered attention from activists and policymakers for their potential to promote public health, sustainable diets, and food sovereignty. However, across country contexts, these programs often fall far short of their transformative potential. It is vital, then, to identify policies and organizing strategies that enable school lunch programs to be redesigned at the national scale. In this article, we use document analysis of historical newspapers and government data to examine the motivating factors and underlying conditions that (...) allowed South Korea’s universal free, eco-friendly school lunch program to become a tool for advancing social justice and ecological goals at the national scale. We analyze the socio-historical evolution and current status of the Korean school lunch program, combining the multi-level perspective with insights from environmental sociology and critical food studies, in order to shed light on the factors that enabled the program to become an innovative niche and articulate the opportunities and challenges it now faces. We identify the state-sponsored creation of what we call “precautionary infrastructure” as a key anchoring mechanism between the school food niche and agri-food regime. Precautionary infrastructure includes new supply chains, certification standards, and sourcing policies that provide a stable market for eco-friendly farms and small-scale producers, while minimizing the environmental health risks of school lunch by delivering organic and pesticide-free ingredients to on-site kitchens that serve free lunches to all students. This analysis offers insight into how public school-lunch programs can become protected niches that help drive sustainability transitions within agri-food systems. (shrink)

In Plato’s Republic, Socrates Famously argues that a just city has to have three distinct classes performing three distinct functions. The producer class is the largest of the three, with the job of taking care of the city’s material needs. It is widely accepted that individual producers in this class are appetitive—appetitive in the sense that they only value bodily and material goods as intrinsic goods and conduct their lives only to maximize those goods.1 In this paper, I want to (...) argue against this reading.The widely accepted picture of appetitive producers is closely tied to the question of what motivates the producers to do what they do. The argument goes something like this. Socrates argues that the soul .. (shrink)

This integrative review aims to provide a synthesis of research findings of health-care professionals’ knowledge, attitudes and behaviours relating to patient capacity to consent to or refuse treatment within the general hospital setting. Search strategies included relevant health databases, hand searching of key journals, ‘snowballing’ and expert recommendations. The review identified various knowledge gaps and attitudinal dispositions of health-care professionals, which influence their behaviours and decision-making in relation to capacity to consent processes. The findings suggest that there is tension between (...) legal, ethical and professional standards relating to the assessment of capacity and consent within health care. Legislation and policy guidance concerning capacity assessment processes are lacking, and this may contribute to inconsistencies in practice. (shrink)

This article examines central tensions in cybernetics, defined as the study of self-organization, communication, automated feedback in organisms, and other distributed informational networks, from its wartime beginnings to its contemporary adaptations. By examining aspects of both first- and second-order cybernetics, the article introduces an epistemological standpoint that highlights the tension between its definition as a theory of recursion and a theory of control, prediction, and actionability. I begin by examining the historical outcomes of the Macy Conferences to provide a context (...) for cybernetics’ initial development for scientific epistemology, ethics, and socio-political thought. I draw extensively from Norbert Wiener, Heinz von Foerster, Ross Ashby, and Gregory Bateson, key figures of this movement. I then elaborate upon certain premises of cybernetics to further elucidate an intellectual history from which to begin to construct a cybernetic epistemology. I conclude by offering the second-order cybernetic concept of recursivity as a model and method for ethico-epistemological questioning that can account for both the constructive potential and the limitations of cybernetics in science and society.

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)

RésuméLe but de cette recherche est de répondre qualitativement à la question de l’évolution de la culture de consommation et des valeurs culturelles associées au sein des cafés d’aujourd’hui de la société coréenne. Cette étude cherche à définir l’aspect synchronique, avec une analyse des comportements de consommation, les attitudes des consommateurs et des concepts d’espace dans les trois stades : le niveau discursif, le niveau sémio-narratif et niveau thématique. Nos travaux s’orientent vers le consommateur par l’utilisation du « parcours génératif (...) de signification » et nous aident à construire des images sur certains aspects de ce phénomène de la culture spatiale pour notre analyse. Ce processus en trois étapes de recherche a été appliqué en utilisant la méthode de l’observation, du questionnaire et de la sémiotique culturelle pour atteindre et trouver les valeurs culturelles fondamentales de cet espace. En fait, les comportements de consommation observés pourraient être interprétés suivants les valeurs /particuliers/ versus /communautaires/ et l’enquête-analyse des attitudes des consommateurs pourraient être définis par les valeurs /professionnels/ versus /sociabilités/ pris dans sa dimension sémantique.

Using an analogy in science and everyday life is a double-edged sword because they are accompanied by alternative ideas, in addition to scientific concepts. Schools and public education explain global warming by making a common analogy between this phenomenon and greenhouse effects. Unfortunately, this analogy sometimes produces various incorrect explanatory mental models. To construct a correct understanding of global warming, it is necessary: first, to investigate the attributes of analogical reasoning; second, to understand these features by restructuring the greenhouse analogy; (...) and third, to explore the problems and benefits of the greenhouse analogy. The characteristics of relations, rather than objects, must be mapped according to the principle of systematicity, but the public tends to preserve the attributes of the base domain, which is mapped relatively easily. In conclusion, certain facets of the prevailing greenhouse analogy cause a distorted public view of climate change. We must use the greenhouse analogy and yet simultaneously emphasize the relations and attributes highlighted and hidden in the analogy during evaluation. (shrink)

Brain–computer interfaces (BCIs) utilizing machine learning techniques are an emerging technology that enables a communication pathway between a user and an external system, such as a computer. Owing to its practicality, electroencephalography (EEG) is one of the most widely used measurements for BCI. However, EEG has complex patterns and EEG-based BCIs mostly involve a cost/time-consuming calibration phase; thus, acquiring sufficient EEG data is rarely possible. Recently, deep learning (DL) has had a theoretical/practical impact on BCI research because of its use (...) in learning representations of complex patterns inherent in EEG. Moreover, algorithmic advances in DL facilitate short/zero-calibration in BCI, thereby suppressing the data acquisition phase. Those advancements include data augmentation (DA), increasing the number of training samples without acquiring additional data, and transfer learning (TL), taking advantage of representative knowledge obtained from one dataset to address the so-called data insufficiency problem in other datasets. In this study, we review DL-based short/zero-calibration methods for BCI. Further, we elaborate methodological/algorithmic trends, highlight intriguing approaches in the literature, and discuss directions for further research. In particular, we search forgenerative model-based andgeometric manipulation-based DA methods. Additionally, we categorize TL techniques in DL-based BCIs intoexplicitandimplicitmethods. Our systematization reveals advances in the DA and TL methods. Among the studies reviewed herein, ~45% of DA studies used generative model-based techniques, whereas ~45% of TL studies used explicit knowledge transferring strategy. Moreover, based on our literature review, we recommend an appropriate DA strategy for DL-based BCIs and discuss trends of TLs used in DL-based BCIs. (shrink)

Culture provides people with rich, detailed, implicit, and explicit knowledge about associations and contingencies. These culture-based expectations allow people to get through their days without much systematic reasoning. Experimental designs that unpack these situated effects of culture on thinking, feeling, and doing can advance bias research and direct policy and intervention.

The primary aim of Jeong Do-jeon’s criticism of Buddhism is, like Mencius, to promote both political and moral actions based on the virtues of Confucianism. In a similar way to Mencius’ denouncement of heretical discourses, Jeong Do-jeon thinks that the disapproval of Buddhism is indispensable for accomplishing the ways of Sages-that is, for effectuating the virtues of Confucianism. Rather than an intellectual debate against Buddhism, Jeong Do-jeon’s criticism of Buddhism is done in the context of political movement, (...) to incorporate Neo-Confucianism as a national ideology. His disapproval, followed and enhanced the discourses of former Confucianists - Zhang Zai, Cheng Brothers, and Zhu Xi - displays both distinctive criticism of Buddhism and better understanding of Neo-Confucianism than other relevant Neo-Confucianists of the Joseon Dynasty. In his book Bulsi-japbyeon 佛氏雜辨, Jeong underlines that Neo-Confucianism, which is based on the concrete facts unlike Buddhism, has realistic practicality, and maintains that the ontological foundation of human morality exists by showing the distinction between the nature(性) and the mind(心). Jeong’s argument has two implications: first, it sheds light on the living moral agent even in fluctuating political conditions; second, it shows that Jeong did not simply reiterate Zhu Xi’s criticism of Buddhism but, based on his particular systematic understanding of overall aspects of Neo-Confucianism, Jeong did criticize Buddhism in his own way. From this point of view, it could be understood that Jeong Do-jeon’s disapproval of Buddhism focuses on the realistic value of the virtues of Confucianism and its actual practice, unlike his predecessors of the Song dynasty who focused on human nature, mind and self-cultivation.

Marketers are increasingly relying on promotional practices (variously labeled as stealth marketing, hybrid messages, covert advertising) based on the diffusion of product information by third parties that appear to be independent of advertisers. In this paper, we examine to what extent the media treat their advertisers favorably, providing these advertisers’ products extra visibility in supposedly neutral editorial content. Empirically, we model the determinant of media coverage of Italian fashion products in an extended dataset of consumer magazines in Italy, France, Germany, (...) UK, and the USA. Research findings show that advertising is an important determinant of product placements in editorial content, and this result is consistent across countries and publishers. Our results imply that resource-rich advertisers engaging in compensatory advertising (that is, advertising investments that compensate poor product quality) might bias media coverage in their favor. Consumers will consequently be exposed twice to favorable messages about those products, in both advertisements and media content, resulting in higher purchases and reduced consumer welfare.

This case study explores the ethical dimensions of the South Korean news media's coverage of the Dr. Woo Suk Hwang scandal and the extant journalism criticism. The study discusses the ethical issues associated with claims that Korean journalists acted too humanely, overemphasized scientific evidence, and were too culturally sensitive in their coverage of the Hwang scandal, and notes the broader implications for journalism ethical theory and criticism suggested by the study's findings. The case explores the differences in the ethical foundations (...) that underlay the press' efforts and the Korean-based criticism of the news media. Among other conclusions, the Hwang scandal illustrates the challenges of universalizing ethical standards in international journalism criticism. (shrink)

Examining the nature of teachers’ emotions and how they are managed and regulated in the act of teaching is crucial to assess the quality of teacher’s instructions. Despite the essential role emotions play in teachers’ lives and instruction, research on teachers’ emotions has not paid much attention on teachers’ state emotions in the context of daily teaching. Significant portion of literature has described teachers’ emotions by foregrounding trait emotions through deductive methodological approaches. This paper explored elementary teachers’ state and trait (...) emotions while preparing for teaching and during teaching, reasons that underlie these emotions, and the relationship between their emotions and the quality of their mathematics instruction. Participants were seven elementary teachers working in the U.S. who participated in Holistic Individualized Coaching (HIC) professional development that consisted of 5 cycles of coaching over an year. For each coaching cycle pre-coaching conversation and post-coaching conversation data were collected regarding state emotions teachers felt in anticipation of teaching and during teaching retrospectively. Also, teachers responded adapted Teaching Emotion Scale (TES) that was aimed to measure trait emotions. In order to compare teachers’ emotions with instructional quality, coaching session were video recorded and analyzed to determine the quality of instruction. Findings of this study showed that teachers reported 6 categories of emotions (positive, negative, neutral, mixed-positive, mixed-negative, and mixed-complex), and often in non-typical ways (e.g., “not nervous”, “anxious but in a positive way”), and mixed emotions were the most dominant category. Also, teachers had more positive emotions anticipating teaching, than actually teaching the lesson, and there was no noticeable change of emotions across the 5 coaching cycles. The reason teachers felt mixed emotions reflected complex and context-specific nature of teaching, which was not articulated in the literature. There were no clear relationships between emotional experiences and instructional quality. This study allowed participants to freely describe their authentic, complex, overlapping, and ambiguous emotions in the context of active teaching, which contributes opening up the possibilities of diversifying teacher emotion research and shows the significance and usefulness of understanding teachers’ state emotions.

What is actual being? The empiricist answers that only what is given to sensation is actual. The rationalist answers that the given to sensation is not actual being but the reasonable connection of the world is a genuine actuality. Kant shows his commitment to empiricism by arguing that only the given to sensation exists.Sensation as an ultimate criterion for actuality is the base of Kant’s critique of the traditional metaphysics. If sensation is proved to be problematic as a criterion for (...) actuality, Kant’s empirical critique of the traditional metaphysics is undermined. This paper will show that in criticizing Kant’s critique of the traditional metaphysics, we can not do so on the basis of an empirical distinction between dream and actuality. On the basis of Hegel’s explanation of the rational actuality,I will show further that the criterion for distinction between dream and actuality is the reasonable connection of the states of affairs.

IntroductionSymptoms of schizophrenia are closely related to aberrant language comprehension and production. Macroscopic brain changes seen in some patients with schizophrenia are suspected to relate to impaired language production, but this is yet to be reliably characterized. Since heterogeneity in language dysfunctions, as well as brain structure, is suspected in schizophrenia, we aimed to first seek patient subgroups with different neurobiological signatures and then quantify linguistic indices that capture the symptoms of “negative formal thought disorder”.MethodsAtlas-based cortical thickness values of 66 (...) patients with first-episode psychosis and 36 healthy controls were analyzed with hierarchical clustering algorithms to produce neuroanatomical subtypes. We then examined the generated subtypes and investigated the quantitative differences in MRS-based glutamate levels [in the dorsal anterior cingulate cortex ] as well as in three aspects of language production features: fluency, syntactic complexity, and lexical cohesion.ResultsTwo neuroanatomical subtypes among patients were observed, one with near-normal cortical thickness patterns while the other with widespread cortical thinning. Compared to the subgroup of patients with relatively normal cortical thickness patterns, the subgroup with widespread cortical thinning was older, with higher glutamate concentration in dACC and produced speech with reduced mean length of T-units and lower repeats of content words, despite being equally fluent.ConclusionWe characterized a patient subgroup with thinner cortex in first-episode psychosis. This subgroup, identifiable through macroscopic changes, is also distinguishable in terms of neurochemistry and language behavior. This study supports the hypothesis that glutamate-mediated cortical thinning may contribute to a phenotype that is detectable using the tools of computational linguistics in schizophrenia. (shrink)

This paper examines the thoughts of two prominent Korean Confucians of the late Goryeo 高麗period, Yi Saek 李穡 and Jeong Do-jeon 鄭道傳. Although they were both renowned as followers of Zhu Xi’s Neo-Confucianism, they held differing views on several important issues. One of these issues was the royal successions of King U 禑王 and King Chang 昌王. Yi Saek considered them to be legitimate rulers of Goryeo, while Jeong Do-jeon denied their legitimacy and accused those involved in their (...) enthronements of treason. In order to conceptualize their differences, I first explain the distinction between the ownership conception and the service conception of political authority introduced by Joseph Chan. Based on this philosophical framework, I analyze and compare the thoughts of Yi Saek and Jeong Do-jeon. My conclusion is that they based political legitimacy on different grounds: for Yi Saek, legitimacy is based on the founder’s achievements in setting up the cultural and political foundation of Goryeo, whereas for Jeong Do-jeon, it is based on the founding king himself, who established the dynasty in 918. Accordingly, I call their views the “founding service” conception and the “founder’s ownership” conception of political authority, respectively. I hope this analysis and comparison of their differing conceptions of political authority can contribute to a better understanding of their political thoughts and the development of the concept of political legitimacy in Korean history.
