BackgroundAttention deficit hyperactivity disorder is clinically diagnosed; however, quantitative analysis to statistically analyze the symptom severity of children with ADHD via the measurement of head movement is still in progress. Studies focusing on the cues that may influence the attention of children with ADHD in classroom settings, where children spend a considerable amount of time, are relatively scarce. Virtual reality allows real-life simulation of classroom environments and thus provides an opportunity to test a range of theories in a naturalistic and (...) controlled manner. The objective of this study was to investigate the correlation between participants’ head movements and their reports of inattention and hyperactivity, and to investigate how their head movements are affected by different social cues of different sensory modalities.MethodsThirty-seven children and adolescents with and without ADHD were recruited for this study. All participants were assessed for diagnoses, clinical symptoms, and self-reported symptoms. A virtual reality-continuous performance test was conducted under four conditions: control, no-cue, visual cue, and visual/audio cue. A quantitativecomparison of the participants’ head movements was conducted in three dimensions using a head-mounted display in a VR classroom environment. Task-irrelevant head movements were analyzed separately, considering the dimension of movement needed to perform the VR-CPT.ResultsThe magnitude of head movement, especially task-irrelevant head movement, significantly correlated with the current standard of clinical assessment in the ADHD group. Regarding the four conditions, head movement showed changes according to the complexity of social cues in both the ADHD and healthy control groups.ConclusionChildren and adolescents with ADHD showed decreasing task-irrelevant movements in the presence of social stimuli toward the intended orientation. As a proof-of-concept study, this study preliminarily identifies the potential of VR as a tool to understand and investigate the classroom behavior of children with ADHD in a controlled, systematic manner.

We aggregate different dimensions of corporate social responsibility (CSR) activities following the stakeholder framework proposed in Clarkson (Acad Manag Rev 20(1), 92–117, 1995) and present consistent evidence that CSR strengths targeting different stakeholders have their unique impact on firm risk and financial performance. Institutional CSR activities that target secondary stakeholders are negatively associated with firm risk, measured by total risk and systematic risk. Technical CSR that target primary stakeholders are positively associated with firm financial performance, measured by Tobin’s Q, ROA, (...) and cash flow returns. Our results, based on a sample of S&P 500 component firms over the period of 1995–2009, are consistent with the risk management view of “altruistic” CSR activities and with the stakeholder salience theory. We also show that the impact of CSR activities on risk varies with the ethical climate, as proved in our subsample analyses on pre- and post-Sarbanes–Oxley periods. Our empirical analyses mitigate possible omitted variables and endogeneity concerns that are often overlooked in previous research. Our findings are robust to alternative CSR measures, to alternative risk and performance measures, and to alternative estimation methods. (shrink)

Despite widespread discussion of the impact of corporate social responsibility activities on consumer perceptions, little research has examined how consumers cope with CSR-based crisis response messages as a bolstering strategy. To fill this gap, we propose a framework integrating situational crisis communication theory with the persuasion knowledge model, applying the model to an experiment with a 2 × 2 × 2 between-subjects factorial design. In Study 1, we found interaction effects between CSR motives and crisis type on word-of-mouth intention and (...) purchase intention. In addition, inferences about CSR motives interacted with perceptions about CSR history on purchase intention. In Study 2, we replicated study 1 and found that crisis responsibility mediated the main effect of crisis type on behavioral intentions, but neither the main effect of CSR motives and CSR history nor the interactions effects among those variables were mediated by crisis responsibility. Our results indicate that consumer inferences from a company’s CSR-based crisis communications play a significant role in increasing consumer behavioral intentions in two situations: when a crisis is accidental and when a CSR history is short. Ethical and theoretical implications are discussed. (shrink)

This study viewed students majoring in public relations as prospective public relations practitioners and explored their perceptions about corporate social responsibility (CSR) as their job attraction condition. The results showed that the students perceived CSR to be an important ethical fit condition of a company. One of the significant findings is that CSR can be an effective reputation management strategy for prospective employees, particularly when a company’s business is suffering. In examining the effect of CSR efforts on attitudinal and behavioral (...) outcomes, person–organization (P–O) fit appeared to serve as a mediator between CSR performances and organizational attractiveness.

The present study explores a neglected area of ethical leadership: lateral behavioral effect from peer team leaders as a key predictor of ethical leadership. Using the lens of social learning theory, we posit that peer team leader ethical voice fosters focal team leader ethical leadership through team leader moral efficacy. In line with social learning perspective, we also posit the moderating effect of ethical role modeling of peer team leader in relationship between peer team leader ethical voice and team leader (...) moral efficacy. We conducted a two-wave study over a 6-week interval between waves from military teams. Our results provided support for all of our hypotheses. In addition, we also found an incremental validity of peer ethical voice behavior by controlling other relevant factors such as upper leaders’ ethical role modeling and peer ethical leadership. Our findings contribute to the advancement of ethical leadership literature by articulating a novel antecedent as well as its boundary condition. (shrink)

With regard to facial emotion recognition, previous studies found that specific facial regions were attended more in order to identify certain emotions. We investigated whether a preferential search for emotion-specific diagnostic regions could contribute toward the accurate recognition of facial emotions. Twenty-three neurotypical adults performed an emotion recognition task using six basic emotions: anger, disgust, fear, happiness, sadness, and surprise. The participants’ exploration patterns for the faces were measured using the Moving Window Technique (MWT). This technique presented a small window (...) on a blurred face, and the participants explored the face stimuli through a mouse-controlled window in order to recognize the emotions on the face. Our results revealed that when the participants explored the diagnostic regions for each emotion more frequently, the correct recognition of the emotions occurred at a faster rate. To the best of our knowledge, this current study is the first to present evidence that an exploration of emotion-specific diagnostic regions can predict the reaction time of accurate emotion recognition among neurotypical adults. Such findings can be further applied in the evaluation and/or training (regarding emotion recognition functions) of both typically and atypically developing children with emotion recognition difficulties.

The purpose of this research is to gain a better understanding of the role of abstraction and idealization in Galileo’s scientific inquiries about the law of inertia, which occupies an important position in the history of science. We argue that although the terms “abstraction” and “idealization” are variously described in the recent literature, the concepts must be adopted to highlight important epistemological problems. In particular, we illustrate the importance of abstraction and idealization for the formation of the law of inertia (...) by establishing a distinction between two types of entities: quasi-ideal entities and idealized entities. These theoretical laws should therefore be justified, using deduction and induction, through quasi-idealized entities based on data from the everyday world. (shrink)

This study explores the relationship between Hofstede’s cultural dimensions and public relations practitioners’ perceptions of corporate social respon- sibility in South Korea. The survey on Korean public relations practitioners revealed that, although Hofstede’s dimensions significantly affect public relations practitioners’ perceptions of CSR, social traditionalism values had more explanatory power than cultural dimensions in explaining CSR attitudes. The results suggest that practitioners’ fundamental ideas about the corporation’s role in society seem to be more important than their cultural values to understand public (...) relations practitioners’ CSR attitudes in Korea.

BackgroundAlthough the Life-Sustaining Treatment (LST) Decision Act was enforced in 2018 in Korea, data on whether it is well established in actual clinical settings are limited. Hospital-acquired pneumonia (HAP) is a common nosocomial infection with high mortality. However, there are limited data on the end-of-life (EOL) decision of patients with HAP. Therefore, we aimed to examine clinical characteristics and outcomes according to the EOL decision for patients with HAP.MethodsThis multicenter study enrolled patients with HAP at 16 referral hospitals retrospectively from (...) January to December 2019. EOL decisions included do-not-resuscitate (DNR), withholding of LST, and withdrawal of LST. Descriptive and Kaplan–Meier curve analyses for survival were performed.ResultsOf 1,131 patients with HAP, 283 deceased patients with EOL decisions (105 cases of DNR, 108 cases of withholding of LST, and 70 cases of withdrawal of LST) were analyzed. The median age was 74 (IQR 63–81) years. The prevalence of solid malignant tumors was high (32.4% vs. 46.3% vs. 54.3%, P = 0.011), and the ICU admission rate was lower (42.9% vs. 35.2% vs. 24.3%, P = 0.042) in the withdrawal group. The prevalence of multidrug-resistant pathogens, impaired consciousness, and cough was significantly lower in the withdrawal group. Kaplan–Meier curve analysis revealed that 30-day and 60-day survival rates were higher in the withdrawal group than in the DNR and withholding groups (log-rank P = 0.021 and 0.018). The survival of the withdrawal group was markedly decreased after 40 days; thus, the withdrawal decision was made around this time. Among patients aged below 80 years, the rates of EOL decisions were not different (P = 0.430); however, mong patients aged over 80 years, the rate of withdrawal was significantly lower than that of DNR and withholding (P = 0.001).ConclusionsAfter the LST Decision Act was enforced in Korea, a DNR order was still common in EOL decisions. Baseline characteristics and outcomes were similar between the DNR and withholding groups; however, differences were observed in the withdrawal group. Withdrawal decisions seemed to be made at the late stage of dying. Therefore, advance care planning for patients with HAP is needed. (shrink)

This study assessed the demographic characteristics of Koreans engaged in leisure sports activities during the COVID-19 pandemic and the differences in their preventive health behaviors and constraints on leisure activities. For this study, the demographic characteristics of 544 leisure sport participants, who were recruited on a nationwide basis, were examined through an online survey. Then, comparisons between groups were performed using independent t-tests, one-way analysis of variance, and multivariate analysis of variance. Women who participated in both indoor and outdoor leisure (...) sports showed higher adoption of health prevention behaviors than their male counterparts, and married individuals who participated in indoor leisure sports showed higher adoption of health prevention behaviors than unmarried participants. Moreover, individuals who participated in both indoor and outdoor leisure sports by themselves had many interpersonal constraints overall, and the group of married individuals who participated in indoor leisure sports showed structural constraints. In conclusion, leisure sports participants have adopted many health prevention behaviors during the COVID-19 pandemic, but this had led to some interpersonal constraints. These results indicate that, in the case of future pandemics, personal and institutional efforts will need to be made to promote participation in leisure sports and prevent excessive social isolation.

Public relations scholars have demonstrated contradictory views regarding the application of universal versus culture-specific approaches for understanding global public relations ethics. However, few comparative studies have empirically explored public relations ethics on a global scale. To that end, this study represents an exploratory attempt to provide a descriptive picture of public relations professional associations and their codes of ethics across 107 countries. In conclusion, we argue that honesty, safeguarding of confidences of clients, and prohibition of conflicts of interest of competing (...) clients should be accepted as the universal values, while other issues, such as free flow of information and fees and gifts, could be understood as the relativistic values specific to a nation's situation and needs.

This squib aims to show that the acceptability status of sluicing examples with an implicit antecedent in islands varies and discusses what is responsible for this variability. After investigating two representative structural approaches to sluicing that posit unpronounced structure in ellipsis sites, namely, Chung et al.’s Representing language: Essays in honor of Judith Aissen, 2010) LF-recovery analysis and Merchant’s PF-deletion analysis, we demonstrate that the acceptability data presented are challenging for both of them. Acceptable sluicing examples with implicit correlates in (...) islands cast doubt on Chung, Ladusaw, and McCloskey’s strict locality requirement, while unacceptable or degraded sluicing examples necessitate additional constraints for Merchant, who employs E-type anaphora as an escape hatch for island violations in sluicing. The gradient nature of the acceptability status of the examples under discussion calls for a non-structural factor that controls their acceptability. We speculate that it is discourse activation of implicit correlates that plays this crucial role. (shrink)

This paper examines the quality and stability of the responsive parenting practices of mothers with infants and the longitudinal links between these practices and children’s self-esteem. Using data presented by the Panel Study on Korean Children, this study identified Korean mothers’ responsive parenting trajectories from birth to age three and examined their associations with children’s self-esteem at first grade. Korean mothers developed one of three responsive parenting patterns from birth to age three: low, moderate, or high. Children’s self-esteem differed according (...) to their mother’s responsive parenting trajectory. First-graders with mothers displaying the low responsive parenting trajectory were more likely to have lower self-esteem than children of mothers with the moderate responsive parenting trajectory and children of mothers with the high responsive parenting trajectory. The longitudinal link between mother-reported responsive parenting patterns during infancy and child-reported self-esteem at first grade was verified. This finding highlights the significance of early responsive parenting from mothers as a predictor of the self-esteem of children in later developmental stages. (shrink)

We explored the need for an ecosystem approach based on relational systems when conducting research on South Korea’s cultural industry. We used Mollard’s (2009. L’ingeniere culturelle. Paris: PUF) idea of the participants in the French cultural system as a key reference and extended it to the notion of the platform, which is the core concept of South Korea’s cultural industry ecosystem (CIE). We also utilized the idea of the “semiotic square of consumption values” from Floch to explicate each platform and (...) participant, which play a significant role in South Korea’s CIE. By defining a role rooted in the relationship and values for each subject (i.e., the production, consumption, authority, and intermediary subjects), we aimed to better understand the ecosystem of the cultural industry and focused on K-pop as a specific aspect of South Korea’s cultural sector by identifying the current identity of each participant.

We suggest that the linguistic characteristics of letters also need to be considered to fully understand how a reader processes printed words. For example, studies in Korean showed that unambiguity in the assignment of letters to their appropriate onset, vowel, or coda slot is one of the main sources of the letter-transposition effect. Indeed, the cognitive system that processes Korean is tuned to the structure of the Korean writing system.

This study assessed the knowledge and perception of human biological materials (HBM) and biorepositories among three study groups in South Korea. The relationship between the knowledge and the perception among different groups was also examined by using factor and regression analyses. In a self‐reporting survey of 440 respondents, the expert group was found more likely to be knowledgeable and positively perceived than the others. Four factors emerged: Sale and Consent, Flexible Use, Self‐Confidence, and Korean Bioethics and Biosafety Action restriction perception. (...) The results indicate that those who are well aware of the existence of biobanks were more positively inclined to receive the Sale and Consent perception. As a result of the need for high quality HBMs and the use of appropriate sampling procedures for every aspect of the collection and use process, the biorepository community should pay attention to ethical, legal, and policy issues.

The purpose of this study was to identify how older Korean people seek information and their desire to participate in decision making about their health care. A total of 165 elderly people living in Seoul, South Korea, participated in the study. Data were collected during individual interviews using the Autonomy Preference Index. The mean information-seeking score was high. The mean score for their desire to participate with a physician in decision making was lower, but this was higher when family members (...) were involved. The study indicates that many older people want to receive information about their health care. Families (or guardians), as well as older people themselves, should be included in the decision-making process. Nurses can encourage older people to express their wishes, while treating each individual with respect. (shrink)

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)

Few studies have addressed the longitudinal links between early temperament types and later problematic smartphone use. This study aims to identify children’s early temperament types at age 3 and to examine the link between the temperament types and smartphone overdependence at age 10. This study utilized a population-based data set presented by the Panel Study on Korean Children. Based on emotionality, activity, and sociability levels at age 3, children were clustered into similar temperament types. Links between the early temperament types (...) and the risks of smartphone overdependence at age 10 were identified through analyses of covariances and binary logistic regressions. Three early temperament types were identified among Korean children: reactive, sociable, and cautious. Children’s smartphone dependence at age 10 differed according to the temperament types identified at age 3. Compared to children with the sociable temperament type, children with the reactive type or the cautious type had an increased risk of smartphone overdependence. The link between temperament types at age 3 and smartphone overdependence at age 10 was meaningful. The cautious children were the most vulnerable group to the risk of smartphone overdependence. Temperament type identification in early years may be a useful measure for screening groups of children who are at risk for problematic smartphone use and need proactive interventions. (shrink)

The cognitive model for social anxiety disorder highlights the role of safety behaviors and post-event processing. We identify the serial mediating effect of state and trait PEP between three types of safety behaviors and social anxiety. Given that the associations between the three subtypes of safety behaviors and two perspectives of PEP have not yet been examined, we aimed to investigate these relationships according to the level of social anxiety. A total of 487 participants participated in an online survey. Participants (...) were classified into two groups, high and low, based on their social anxiety scores. We used Social Behavior Questionnaire to distinguish three types of safety behaviors and the State and Trait versions of the Post-Event Processing Inventory to identify two perspectives of PEP. We used descriptive statistics and an independent t-test to compare the high and low social anxiety groups. Mediation effects were examined using mediation analysis and bootstrapping with 5,000 replications. The results showed that the three safety behaviors had different effects on social anxiety via PEP. In the high social anxiety group, avoidance behavior and anxiety-symptom control predicted social anxiety positively, whereas impression management did not. However, with state PEP and trait PEP as mediators, impression management and avoidance behavior positively predicted social anxiety but not anxiety-symptom control. In the low social anxiety group, only avoidance behavior was significantly related to social anxiety, but when the state and trait PEP were mediated, the effect disappeared. These results indicated that impression management could affect social anxiety only when mediated by PEP in people with high social anxiety. A better understanding of the content and processes underpinning safety behavior and PEPs might have important implications for the prevention and treatment of social anxiety disorder. (shrink)

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.

This study was designed to examine the prevalence of a code of ethics and to analyze its content among public relations agencies in the United States. Of the 1,562 public relations agencies reviewed, 605 (38.7%) provided an ethical statement. Among the ethical statements provided by these public relations agencies, ‹respect to clients,’ ‹service,’ ‹strategic,’ and ‹results’ were the values most frequently emphasized. On the other hand, ‹balance,’ ‹fairness,’ ‹honor,’ ‹social responsibility,’ and ‹independence’ were the least frequently mentioned in the ethical (...) codes. Also, none of the sampled agencies included any sanctions regarding enforcement of their particular codes of ethics. (shrink)

This study examined the relationship between person–organization (PO) fit on prosocial identity (prosocial PO fit) and various employee outcomes. The results of polynomial regression analysis based on a sample of 589 hospital employees, which included medical doctors, nurses, and staff, indicate joint effects of personal and organizational prosocial identity on the development of a sense of organizational identification and on the engagement in prosocial behaviors toward colleagues, organizations, and patients. Specifically, prosocial PO fit had a curvilinear relationship with organizational identification, (...) such that organizational identification increased as organizational prosocial characteristics increased toward personal prosocial identity and then decreased when the organizational prosocial characteristics exceeded the personal prosocial identity. In addition, organizational identification and prosocial behaviors increased as both personal and organizational prosocial identity increased from low to high. (shrink)
