With the increasing demand for ethical standards in the current business environment, ethical leadership has received particular attention. Drawing on self-verification theory and social exchange theory, this study investigated the effect of leaders’ core self-evaluation on the display of ethical leadership and the moderating role of employees’ exchange ideology in the relationship between ethical leadership and employees’ job performance. Consistent with the hypotheses, the results from a sample of 225 dyads of employees and their immediate leaders showed a positive relationship (...) between leaders’ core self-evaluation and ethical leadership. Moreover, the results showed that ethical leadership mediates the effects of leaders’ core self-evaluation on employees’ job performance. Furthermore, we found that employees’ exchange ideology moderates the relationship between ethical leadership and job performance. The theoretical and practical implications of these findings are discussed. (shrink)

In this paper, we investigate a new model theoretical tree property (TP), called the antichain tree property (ATP). We develop combinatorial techniques for ATP. First, we show that ATP is always witnessed by a formula in a single free variable, and for formulas, not having ATP is closed under disjunction. Second, we show the equivalence of ATP and [Formula: see text]-ATP, and provide a criterion for theories to have not ATP (being NATP). Using these combinatorial observations, we find algebraic examples (...) of ATP and NATP, including pure groups, pure fields and valued fields. More precisely, we prove Mekler’s construction for groups, Chatzidakis’ style criterion for pseudo-algebraically closed (PAC) fields, and the AKE-style principle for valued fields preserving NATP. We give a construction of an antichain tree in the Skolem arithmetic and atomless Boolean algebras. (shrink)

Hip fractures are common and serious injuries in the geriatric population. Obtaining informed consent for surgery in geriatric patients can be difficult due to the high prevalence of comorbid cognitive impairment. Given that virtually all patients with hip fractures eventually undergo surgery, and given that delays in surgery are associated with increased mortality, we argue that there are select instances in which it may be ethically permissible, and indeed clinically preferable, to initiate surgical treatment in cognitively impaired patients under the (...) doctrine of presumed consent. In this paper, we examine the boundaries of the license granted by presumed consent and use the example of geriatric hip fracture to build an ethical framework for understanding the doctrine of presumed consent. The license to act under presumed consent requires three factors: patient incapacity, clinical urgency and clarity on the correct course of action. All three can apply to geriatric hip fracture. The typical patient frequently lacks capacity. Delays in initiating surgical treatment are associated with markedly increased mortality rates. Last, there appears to be consensus that surgery is the preferred treatment. Nonetheless, because there is a window of safe delay during which treating physicians can stabilize the patient, address reversible causes of cognitive impairment and identify surrogate decision makers, presumed consent should be invoked only as a method of last resort. A medical situation need not be characterized by risk of imminent and certain death for presumed consent to be relevant. Rather, there are two distinct windows that must be considered: the time interval in which action may be delayed without danger, and the time interval needed to obtain a better form of consent. Presumed consent is appropriate only when the latter exceeds the former. (shrink)

A tic disorder (TD) is a neurodevelopmental disorder characterized by tics, which are repetitive movements and/or vocalizations that occur due to aberrant sensory gating. Its pathophysiology involves dysfunction in multiple parts of the cortico-striato-thalamo-cortical circuits. Spontaneous brain activity during the resting state can be used to evaluate the baseline brain state, and it is associated with various aspects of behavior and cognitive processes. Theta–gamma coupling (TGC) is an emerging technique for examining how neural networks process information through interactions. However, the (...) resting-state TGC of patients with TD and its correlation with cognitive function have not yet been studied. We investigated the resting-state TGC of 13 patients with TD and compared it with that of 13 age-matched healthy children. The participants underwent resting-state electroencephalography with their eyes closed. At the global level, patients with TD showed a significantly lower resting-state TGC than healthy children. Resting-state TGC with the eyes closed was significantly negatively correlated with the attention quotient calculated for omission errors in a selective visual attention test. These findings indicate that the resting-state brain network, which is important for the attentional processing of visual information, is dysfunctional in patients with TD. Additionally, these findings support the view that TGC reflects information processing and signal interactions at the global level. Patients with TD may have difficulty gating irrelevant sensory information in the resting state while their eyes are closed. (shrink)

Although some regulatory frameworks for the occupational health and safety of nanotechnology workers have been developed, worker safety and health issues in these laboratory environments have received less attention than many other areas of nanotechnology regulation. In addition, workers in nanotechnology labs are likely to face unknown risks and hazards because few of the guidelines and rules for worker safety are mandatory. In this article, we provide an overview of the current health and safety guidelines for nanotechnology laboratory workers by (...) exploring guidelines from different organizations, including the Department of Energy Nanoscale Science Research Centers, Massachusetts Institute of Technology, the National Institutes of Health, the National Institute for Occupational Safety and Health, the Occupational Safety and Health Administration, Texas A&M University, and University of Massachusetts-Lowell. After discussing these current guidelines, we apply an ethical framework to each set of guidelines to explore any gaps that might exist in them. By conducting this gap analysis, we are able to highlight some of the weaknesses that might be important for future policy development in this area. We conclude by outlining how future guidelines might address some of these gaps, specifically the issue of workers’ participation in the process of establishing safety measures and the development and enforcement of more unified guidelines.

We prove the preservation theorems for NATP; many of them extend the previously established preservation results for other model-theoretic tree properties. Using them, we also furnish proper examples of NATP theories which are simultaneously TP2 and SOP. First, we show that NATP is preserved by the parametrization and sum of the theories of Fraïssé limits of Fraïssé classes satisfying strong amalgamation property. Second, the preservation of NATP for two kinds of dense/co-dense expansions, i.e. the theories of lovely pairs and of (...) [Formula: see text]-structures for geometric theories, and dense/co-dense expansion on vector spaces is proved. Next, we prove the preservation of NATP for the generic predicate expansion and the pair of an algebraically closed field and its distinguished subfield; for the latter, not only NATP, but also the preservation of NTP1 and NTP2 is considered. Finally, we present some proper examples of NATP theories using the results proved in this paper, including the parametrization of DLO and the expansion of an algebraically closed field by adding a generic linear order. In particular, we show that the model companion of the theory of algebraically closed fields with circular orders (ACFO) is NATP. (shrink)

Since the turn of the millennium South Korea has continued to grapplewith transgressions that shook the nation to its core. Following the serial killings of Korea's raincoat killer, the events that led to the dissolution of the United Progressive Party, the criminal negligence of the owner and also the crew members of the sunken Sewol Ferry, as well as the political scandals of 2016, there has been much public debate about morality, transparency, and the law in South Korea. Yet, despite (...) its prevalence in public discourse, transgression in Korea has not received proper scholarly attention. Transgression in Korea challenges the popular conceptions of transgression as resistance to authority, the collapse of morality, and an attempt at self- empowerment. Examples of transgression from premodern, modern, and contemporary Korea are examined side by side to underscore the possibility of reading transgression in more ways than one. These examples are taken from a devotional screen from medieval Korea, trickster tales from the late Choson period, reports about flesheating humans, newspaper articles about same- sex relationships from colonial Korea, and films about extramarital affairs, wayward youths, and a vengeful vigilante. Bringing together specialists from various disciplines such as history, art history, anthropology, premodern literature, religion, and film studies, the context- sensitive readings of transgression provided in this book suggest that transgression and authority can be seen as forming something other than an antagonistic relationship.

This article aims to critique the recent claim raised in Korea that Toegye's theory on lifa 理發 “negates the activity of li.” In my view, although the idea of lifa is not clearly presented by Zhu Xi and even contradicts his conception of “non-action of li,” it recovers fundamental Confucian principle and reaffirms valuable attributes of humanity. Toegye's notion of lifa establishes the ground for distinguishing humans from animals by emphasizing the subjective spontaneity and activity of moral rationality. To expound (...) on this, I shall first review the concepts of li, qi, heart/mind, nature, feeling, and their relationships in Toegye's philosophy. Then, I shall examine the significance of lifa and criticize that the claims which deny the activity of li are ungrounded. (shrink)

Human resource management in managing environmental, social, governance, or corporate social responsibility initiatives has been recently raised. Yet, little attention has been paid to integrating CSR and HRM. Our primary goal was to identify how and whether certain HR practices are critical for developing employee capability to operate in firms with active CSR initiatives. We first examine the impact of external CSR activities on firm-level work outcomes. Moreover, we attempt to identify a choice of particular HR practices that could be (...) aligned with external CSR activities. We then empirically examine how each HR practice interacts with external CSR activities that influence employee retention and labor productivity. Using three longitudinal datasets conducted by the government-sponsored research institution over 154 publicly traded Korean firms for five waves of survey years, the results show that external CSR has a limited impact on employee retention and labor productivity. However, when external CSR activities are combined with a specific set of HR practices, including person-organization fit-based selection, performance-based pay, extensive investment of training and development, and employee suggestion program, the impact of external CSR on employee work outcomes is more substantial. The results indicate that external CSR and a particular set of HR practices as internal CSR can be complementary and generate a positive interaction on creating sustainable human capabilities.

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)
