SignificanceElectrical burns can cause severe damage to the nervous system, resulting in autonomic dysfunction with reduced cerebral perfusion. However, few studies have investigated these consequences.AimTo elucidate changes in prefrontal cerebral hemodynamics using functional near-infrared spectroscopy (fNIRS) during the head-up tilt table test (HUT) for patients with electrical burns.ApproachWe recruited 17 patients with acute electrical burns within 1 week after their accidents and 10 healthy volunteers. The NIRS parameters acquired using an fNIRS device attached to the forehead were analyzed in five (...) distinct HUT phases.ResultsBased on their HUT response patterns, patients with electrical burns were classified into the group with abnormal HUT results (APG, n = 4) or normal HUT results (NPG, n = 13) and compared with the healthy control (HC, n = 10) participants. We found trends in hemodynamic changes during the HUT that distinguished HC, NPG, and APG. Reduced cerebral perfusion and decreased blood oxygenation during the HUT were found in both the NPG and APG groups. Patients with electrical burns had autonomic dysfunction compared to the HC participants.ConclusionsUsing fNIRS, we observed that acute-stage electrical burn injuries could affect cerebral perfusion.

In this article, we focus on problem solving talk in the business meeting event. We zoom in on the processes of formulating, negotiating and ratifying an issue as a problem, and we argue that individuals negotiate their stances in relation to their perceived/projected professional roles. The processes of problem-solving are, simultaneously, processes of self/other positioning. We take an Interactional Sociolinguistic perspective and draw on audio-recorded meeting talk collected in a multinational corporate workplace. Our analysis shows that interactants draw on issues (...) of accountability, perceived/projected responsibilities and expertise in pursuit of their own interactional agenda in the problem-solving meeting. We close the article with directions for further research. (shrink)

In this article, we examine the association between ethics and disclosure and the impact of this association on the long-term, post-issue performance of seasoned equity offerings (SEOs). We argue that firms with extensive disclosure are less likely to face information problems, and more likely to lead to an active shareholder monitoring, and therefore, engage in fewer unethical activities, such as aggressive earnings manipulation, and have better long-term, post-issue performance. Consistent with these predictions, this study presents evidence that disclosure is negatively (...) related to unethical earnings manipulation and positively associated with long-term, post-issue performance. In particular, we find that long-term, post-issue SEO underperformance is significantly less for firms with extensive disclosure and conservative earnings management than firms with less disclosure and aggressive earnings management. We interpret this evidence to mean that over the long run, the capital market values ethical financial reporting and corporate efforts to incorporate social responsibility into their decision-making processes, for example, by enhancing information transparency through voluntary disclosure.

In this study, we examine whether corporate environmental responsibility plays a role in enhancing operating performance in the financial services sector. Because achieving success with CER investing is often a long-term process, we maintain that by effectively investing in CER, executives can decrease their firms’ environmental costs, thereby enhancing operating performance. By employing a unique environmental dataset covering 29 countries, we find that the reducing of environmental costs takes at least 1 or 2 years before enhancing return on assets. We (...) also find that reducing environmental costs has a more immediate and substantial effect on the performance of financial services firms in well-developed financial markets than in less-developed financial markets. These results are economically and statistically significant and robust even after alleviating endogeneity and using an additional performance measure. We interpret our empirical results as supporting the social impact and reputation-building hypothesis. Our findings also suggest that policy makers dealing with corporate sustainability management should pursue an environment-centered industry policy not only at the manufacturing sector but also at the financial services sector, as firms in both sectors with lower environmental costs perform better.

Frontoparietal connectivity has been suggested to be important in conscious processing and its interruption is thought to be one mechanism of general anesthesia. Data in animals demonstrate that feedforward processing of information may persist during the anesthetized state, while feedback processing is inhibited. We investigated the directionality and functional organization of frontoparietal connectivity in 10 human subjects anesthetized with propofol on two separate occasions. Multichannel electroencephalography and a computational method of assessing directed functional connectivity were employed. We demonstrate that directed (...) feedback connectivity is diminished with loss of consciousness and returns with responsiveness to verbal command. We also applied the Dendrogram classification method to assess the global organization of directed functional connectivity during consciousness and anesthesia. We demonstrate a state-specific hierarchy and subject-specific subhierarchy in functional organization. These data support the hypothesis that specific states of human consciousness are defined by specific states of frontoparietal connectivity. (shrink)

BackgroundElectronic cigarettes as substitute devices for regular tobacco cigarettes have been increasing in recent times. We investigated neuronal substrates of vaping e-cigs and smoking r-cigs from r-cig smokers.MethodsTwenty-two r-cig smokers made two visits following overnight smoking cessation. Functional magnetic resonance imaging data were acquired while participants watched smoking images. Participants were then allowed to smoke either an e-cig or r-cig until satiated and fMRI data were acquired. Their craving levels and performance on the Montreal Imaging Stress Task and a 3-back (...) alphabet/digit recognition task were obtained and analyzed using two-way repeated-measures analysis of variance. Regions-of-interest were identified by comparing the abstained and satiated conditions. Neuronal activation within ROIs was regressed on the craving and behavioral data separately.ResultsCraving was more substantially reduced by smoking r-cigs than by vaping e-cigs. The response time for the 3-back task was significantly shorter following smoking r-cigs than following vaping e-cigs = 5.3, p = 0.035). Neuronal activations of the right vermis, right caudate, and right superior frontal gyrus were significantly correlated with the RT for the 3-back task only for smoking r-cigs.ConclusionOur findings suggest that insufficient satiety from vaping e-cigs for r-cigs smokers may be insignificant effect on working memory function.

This study examines the relation between corporate social responsibility and institutional investor ownership, and the impact of this relation on stock return volatility. We find that institutional ownership does not strictly increase or decrease in CSR; rather, institutional ownership is a concave function of CSR. This evidence suggests that institutional investors do not see CSR as strictly value-enhancing activities. Institutional investors adjust their percentage of ownership when CSR activities go beyond the perceived optimal level. Employing the path analysis, we also (...) examine the mediating effect of institutional ownership on the relation between CSR and stock return volatility. We find that CSR decreases stock return volatility at a decreasing rate through its effect on institutional ownership. Our results remain robust under several different CSR measures and estimation methods. (shrink)

The cognitive unbinding paradigm suggests that the synthesis of neural information is attenuated by general anesthesia. Here, we analyzed the functional organization of brain activities in the conscious and anesthetized states, based on functional segregation and integration. Electroencephalography recordings were obtained from 14 subjects undergoing induction of general anesthesia with propofol. We quantified changes in mean information integration capacity in each band of the EEG. After induction with propofol, mean information integration capacity was reduced most prominently in the γ band (...) of the EEG . Furthermore, we demonstrate that loss of consciousness is reflected by the breakdown of the spatiotemporal organization of γ waves. We conclude that induction of general anesthesia with propofol reduces the capacity for information integration in the brain. These data directly support the information integration theory of consciousness and the cognitive unbinding paradigm of general anesthesia. (shrink)

There is a growing literature on corporate social responsibility, but few have focused on the implications of business groups for CSR. We examine the antecedents and outcomes of CSR behaviors of group firms in Korea. We find that group affiliation is associated with higher CSR overall and for its major societal and environmental components. However, the ownership disparity between cash flow and control by controlling inside shareholders is associated with lower CSR, consistent with opportunistic rent expropriation theory. We further find (...) that CSR initiatives can impact group firms positively in the event of bad events, consistent with insurance theory. This motive for CSR as a means of enhancing reputation capital to buffer the bad events is pronounced for group firms because of group-wide dissemination of negative reputational externality.

BackgroundExperience with open disclosure and its study are restricted to certain western countries. In addition, there are concerns that open disclosure may be less suitable in non-western countries. The present study explored and compared the in-depth perceptions of the general public and physicians regarding open disclosure in Korea.MethodsWe applied the COREQ checklist to this qualitative study. We conducted 20 in-depth interviews and four focus group discussions with 16 physicians and 18 members of the general public. In-depth interviews and focus group (...) discussions were performed according to semi-structured guidelines developed according to a systematic review of open disclosure. We conducted a directed content analysis by analyzing the verbatim transcripts and field notes in accordance with the predetermined guidelines.ResultsOpen disclosure perceptions were summarized in terms of the “five Ws and one H”. All physician and general public participants acknowledged the normative justifiability of open disclosure. The participants mostly agreed on the known effects of open disclosure, but the physicians had negative opinions on its expected effects, such as decreased intention of the general public to file lawsuits and increased credibility of medical professionals. Generally, the participants thought that open disclosure is required for medical errors causing major harm. However, the physicians and general public had conflicting opinions on the need for open disclosure of near misses. Most physicians did not know how to conduct open disclosure and some physicians had bad experiences due to inappropriate or incomplete open disclosure.ConclusionPhysicians and the general public in Korea acknowledge the need for open disclosure. Guidelines according to the type of patient safety incident are required to encourage physicians to more readily conduct open disclosure. Furthermore, hospitals need to consider organizing a dedicated team and hiring experts for open disclosure. (shrink)

BackgroundThis study aimed to identify the healthcare providers’ experience and perspectives toward end-of-life care decisions focusing on end-of-life discussion and physician’s order of life-sustaining treatment documentation in Korea which are major parts of the Life-Sustaining Treatment Act.MethodsA cross-sectional survey was conducted using a questionnaire developed by the authors. A total of 474 subjects—94 attending physicians, 87 resident physicians, and 293 nurses—participated in the survey, and the data analysis was performed in terms of frequency, percentage, mean and standard deviation using the (...) SPSS 24.0 program.ResultsStudy results showed that respondents were aware of terminal illness and physician’s order of life-sustaining treatment in Korea well enough except for some details. Physicians reported uncertainty in terminal state diagnosis and disease trajectory as the most challenging. Study participants regarded factors (related to relationships and communications) on the healthcare providers’ side as the major impediment to end-of-life discussion. Study respondents suggested that simplification of the process and more staff are required to facilitate end-of-life discussion and documentation.ConclusionBased on the study results, adequate education and training for better end-of-life discussion are required for future practice. Also, a simple and clear procedure for completing a physician’s order of life-sustaining treatment in Korea should be prepared and legal and ethical advice would be required. Since the enactment of the Life-Sustaining Treatment Act, several revisions already have been made including disease categories, thus continuous education to update and support clinicians is also called for.

The most famous korean Poet Jiha Kim had turned toward the thoughts for life in the beginning of eighties in Korea. I will here introduce the causes and the basis of his thoughts. It has been recognized already that Korean traditional philosophy of DongHak (the learning in the East Asia) and the western philosophies, ie the theology of liberation, the philosophy of Bergson or Deleuze had influenced much to his thoughts for life. But the most determinate basis of his thoughts, (...) I think is the experiences in the movements for democracy in Korea. His thoughts represent the dear believes which the mass have won since the seventies.These believes resides in the not exhausting life powers of the Minjung (Peoples repressed and alienated). His thoughts has succeed to the modern philosophy of democratic resistance but also criticised the severe problems of modern philosophies. After the democratic movement in Korea there has taken place the cultural revolution movements in Korea by new generations, which can not be adjoined to the previous democratic movements without the thoughts for life of Jiha Kim.

We investigate how two different types of conflict (task conflict and relationship conflict) at two different levels (individual-level and team-level) influence individual team commitment. The analysis was conducted using data we collected from 193 employees in 31 branch offices of a Korean commercial bank. The relationships at multiple levels were tested using hierarchical linear modeling (HLM). The results showed that individual-level relationship conflict was negatively related to team commitment while individual-level task conflict was not. In addition, both team-level task and (...) relationship conflict were negatively associated with team commitment. Finally, only team-level relationship conflict significantly moderated the relationship between individual-level relationship conflict and team commitment. We further derive theoretical implications of these findings. (shrink)

The main purpose of this study was to investigate the impact of perceived HR practices on affective commitment and turnover intention. This study explored which HR practices were relatively more important in predicting affective commitment and turnover intention. A total of 302 employees from the United States and 317 from South Korea completed the same questionnaires for assessing the aforementioned relationships. The results illustrated that among perceived HR practices, internal mobility had the most significant association with turnover intention in both (...) the US and South Korea. While internal mobility was a stronger predictor of affective commitment for the US sample, training was the most important variable for predicting affective commitment in South Korea. The second purpose of the study was to examine whether individuals’ positive affect influences the relationship between perceived HR practices and affective commitment and turnover intention. In the US, positive affect moderated the relationship between perceived HR practices and affective commitment and turnover intention such that the relationships were stronger for individuals reporting high positive affect relative to those reporting low positive affect. However, these relationships were not significant in South Korea. We discuss the implications of these results, study limitations, and practical suggestions for future research. (shrink)

The belief in free will has been frequently challenged since Benjamin Libet published his famous experiment in 1983. Although Libet’s experiment is highly dependent upon subjective reports, no study has been conducted that focused on a first-person or introspective perspective of the task. We took a neurophenomenological approach in an N = 1 study providing reliable and valid measures of the first-person perspective in conjunction with brain dynamics. We found that a larger readiness potential is attributable to more frequent occurrences (...) of self-initiated movements during negative deflections of the slow cortical potentials . These negative deflections occur in parallel with an inner impulse reported by an expert meditator which may in turn lead to a voluntary act. We demonstrate in this proof-of-principle approach that the first-person perspective obtained by an expert meditator in conjunction with neural signal analysis can contribute to our understanding of the neural underpinnings of voluntary acts.
