This paper describes the processes of cognitive modeling and representation of human expertise for developing an ontology and knowledge base of an expert system. An ontology is an organization and classification of knowledge. Ontological engineering in artificial intelligence (AI) has the practical goal of constructing frameworks for knowledge that allow computational systems to tackle knowledge-intensive problems and supports knowledge sharing and reuse. Ontological engineering is also a process that facilitates construction of the knowledge base of an intelligent system, which can (...) be defined as a computer program that can duplicate problem-solving capabilities of human experts in specific areas. This paper presents the processes of knowledge acquisition, analysis, and representation, which laid the basis for ontology construction. In this case, the processes are applied in ontological engineering for construction of an expert system in the domain of monitoring of a petroleum production and separation facility. The acquired knowledge was also formally represented in two knowledge acquisition tools. (shrink)

Practice guidelines are an increasingly relevant feature of health insurance. One hundred and seventy-eight million people in the United States have some form of private health insurance coverage; coverage for 150 million of them is employment-related. Traditionally, this coverage was provided by employers purchasing a group contract under which an insurance carrier provided indemnity coverage for employees—that is, the insurance company paid all usual, customary, and reasonable charges incurred by an employee for medical care, subject in some cases to an (...) annual deductible and to a percentage of covered expenses, co-paid by the employee, for each service. In recent years, however, employers in greater numbers have switched to so-called self-insurance plans in which employees’ health care claims are paid directly by the employer. (shrink)

Childhood adversity is associated with altered or dysregulated stress reactivity; these altered patterns of physiological functioning persist into adulthood. Evidence from both preclinical animal models and human neuroimaging studies indicates that early life experience differentially influences stressor-evoked activity within central visceral neural circuits proximally involved in the control of stress responses, including the subgenual anterior cingulate cortex (sgACC), paraventricular nucleus of the hypothalamus (PVN), bed nucleus of the stria terminalis (BNST) and amygdala. However, the relationship between childhood adversity and the (...) resting-state connectivity of this central visceral network remains unclear. To this end, we examined relationships between childhood threat and childhood socioeconomic deprivation, the resting-state connectivity between our regions of interest (ROIs), and affective symptom severity and diagnoses. We recruited a transdiagnostic sample of young adult males and females (n= 100; mean age = 27.28,SD= 3.99; 59 females) with a full distribution of maltreatment history and symptom severity across multiple affective disorders. Resting-state data were acquired using a 7.2-min functional magnetic resonance imaging (fMRI) sequence; noted ROIs were applied as masks to determine ROI-to-ROI connectivity. Threat was determined by measures of childhood traumatic events and abuse. Socioeconomic deprivation (SED) was determined by a measure of childhood socioeconomic status (parental education level). Covarying for age, race and sex, greater childhood threat was significantly associated with lower BNST-PVN, amygdala-sgACC and PVN-sgACC connectivity. No significant relationships were found between SED and resting-state connectivity. BNST-PVN connectivity was associated with the number of lifetime affective diagnoses. Exposure to threat during early development may entrain altered patterns of resting-state connectivity between these stress-related ROIs in ways that contribute to dysregulated neural and physiological responses to stress and subsequent affective psychopathology.

Education is so strongly emphasized in the Chinese culture that academic success is widely regarded as the only indicator of success, while too much physical activity is often discouraged because it drains energy and affects academic concentration. This study investigated the relations among academic achievement, self?esteem, school conduct and physical activity level. The participants were 333 Chinese pre?adolescents (aged 8?12) in Hong Kong. Examination results and conduct grades were obtained from the school records. Global self?esteem was measured with the Physical (...) self?description questionnaire (PSDQ), while physical activity patterns of the children were assessed with the Physical activity questionnaire for children (PAQ?C). Results showed that high academic achievers consistently attained better school conduct marks. However, physical activity level was quite an independent entity that was related neither to academic achievement nor school conduct. Furthermore, regression analyses showed that only academically high?achieving boys and physically active boys had higher self?esteem. (shrink)

This study examines the relationship between procedural justice and employee job insecurity, and the boundary conditions of this relationship. Drawing upon uncertainty management theory and ethical leadership research, we hypothesized that procedural justice is negatively related to job insecurity, and that this relationship is moderated by ethical leadership. We further predicted that the moderating relationship would be more pronounced among employees with a low power distance orientation. We tested our hypotheses using a sample of 381 workers in Macau and Southern (...) China. The results support all of our hypotheses. The implications of these results for research and practice are discussed. (shrink)

Participatory action research (PAR) is a form of community-driven qualitative research which aims to collaboratively take action to improve participants’ lives. This is generally achieved through cognitive, reflexive learning cycles, whereby people ultimately enhance their wellbeing. This approach builds on two assumptions: (1) participants are able to reflect on and prioritize difficulties they face; (2) collective impetus and action are progressively achieved, ultimately leading to increased wellbeing. This article complicates these assumptions by analyzing a two-year PAR project with mothers of (...) disabled children from a South African urban settlement. Participant observation notes, interviews, and a group discussion served as primary data. We found that mothers’ severe psychological stress and the strong intersectionality of their daily challenges hampered participation. Consequently, mothers considered the project ‘inactionable’. Yet, many women quickly started expressing important individual and collective wellbeing transformations. To understand these ‘unlikely’ transformations, a feminist relational account, in particular, that of relational wellbeing, proves essential. We reflect on the consequences of these findings for the dominant PAR methodology and operationalization, and propose to sensitize future PAR with marginalized women by employing relational wellbeing as an overarching ontological awareness.

This study empirically examines how Chinese executives perceive the role of guanxi and ethics played in their business operations. By factor-analyzing 850 valid replies collected from a comprehensive survey, the present study identifies three distinct ethics-related attitudes and two distinct guanxi-related attitudes for Chinese executives. The cluster analysis of the composite scores of these five attitudinal factors further indicates the existence of three distinct groups of Chinese executives that vary in their ethics and guanxi orientations. The three groups are unethical (...) profit seeker (UPS), anti-governance, guanxi-cultivator (AGGC), and apathetic executive (AE). The three groups are also found to be significantly different in such demographic characteristics as age and the ownership structure of the serving organization. Specifically, the inter-group comparison suggests that younger Chinese executives, and those working for privately-owned firms and joint ventures are more inclined to engage in unethical activities for profits. These findings provide useful insights for international investors to formulate their human resource and negotiation strategies in China. (shrink)

In this theoretical paper, motives for CSR are considered. An underlying assumption is that the commercial imperative is not the sole driver of CSR decision-making in private sector companies, but that the formal adoption and implementation of CSR by corporations could be associated with the changing personal values of individual managers. These values may find expression through the opportunity to exercise discretion, which may arise in various ways. It is suggested that in so far as CSR initiatives represent individuals' values, (...) so the responsibility in evidence is less obviously corporate. Our emphasis on personal initiative is intended to counter a tendency to view the corporation as the agent, and may serve to remind us that individuals can, indeed, make a difference. (shrink)

The effectiveness of complaint handling and service recovery policies in customer retention has been the focus of both scholars and service organizations. In the past decade, Justice Theory has provided the basis of the dominant theoretical framework for complaint management and service recovery. However, it does not explicitly address unfair trade practices, which constitute an ethical issue. Favorable outcomes in complaint handling may not be able to restore the reputation of a company and the potential harm perceived by consumers. Using (...) face-to-face interviews, this study applies Fairness Theory to explore the psychological responses of consumers in the post-complaint phase, particularly in ethical judgment. The findings suggest that an unfavorable outcome in the post-complaint stage leads to counterfactual thinking by the consumer about the consumer's state of well-being. The complaint must be due to the discretionary actions of the service provider whose accountability is assessed. Those harmful actions are then judged against an ethical standard. Explanations can reduce blame, and their effectiveness is moderated by outcome favorability but not ethical judgment. Favorable outcome, captured by "Would Perception," has only limited influence on Perceived Potential Harm (PPH), which is an important determinant of ethical judgment. This study makes both theoretical and practical contributions. It is the first study to validate Fairness Theory empirically and apply it to complaint handling as a complement of Justice Theory in the information and communication technology (ICT) service context. The study indicates that customers may condemn a service provider because of PPH even though the outcome is favorable. Unfair trade practices are what make customers hate ICT service providers.

The economic globalization process has integrated different competitive markets and pushes firms in different countries to improve their managerial and operational efficiencies. Given the recent empirical evidence for the benefits to firms and stakeholders of good corporate governance (CG) practice, it is expected that good CG practice would be a common strategy for firms in different countries to meet the increasingly intense competition; however, this is not the case. This study examines the differences in CG practices in firms across different (...) countries using the concept of ethical sensitivity. Through the regression analysis of 271 firms in 12 countries and regions, it is found that Hofstede’s cultural dimensions can explain the differences in CG practices. Furthermore, the results demonstrate the influence of culture on ethical sensitivity, which eventually determines the CG practices in different regions. (shrink)

Many male traits are well explained by sexual selection theory as adaptations to mating competition and mate choice, whereas no unifying theory explains traits expressed more in females. Anne Campbell's “staying alive” theory proposed that human females produce stronger self-protective reactions than males to aggressive threats because self-protection tends to have higher fitness value for females than males. We examined whether Campbell's theory has more general applicability by considering whether human females respond with greater self-protectiveness than males to other threats (...) beyond aggression. We searched the literature for physiological, behavioral, and emotional responses to major physical and social threats, and found consistent support for females' responding with greater self-protectiveness than males. Females mount stronger immune responses to many pathogens; experience a lower threshold to detect, and lesser tolerance of, pain; awaken more frequently at night; express greater concern about physically dangerous stimuli; exert more effort to avoid social conflicts; exhibit a personality style more focused on life's dangers; react to threats with greater fear, disgust, and sadness; and develop more threat-based clinical conditions than males. Our findings suggest that in relation to threat, human females have relatively heightened protective reactions compared to males. The pervasiveness of this result across multiple domains suggests that general mechanisms might exist underlying females' unique adaptations. An understanding of such processes would enhance knowledge of female health and well-being. (shrink)

��We describe a comprehensive framework for text un- derstanding, based on the representation of context. It is designed to serve as a representation of semantics for the full range of in- terpretive and inferential needs of general natural language pro- cessing. Its most distinctive feature is its uniform representation of the various simple and independent linguistic sources that play a role in determining meaning: lexical associations, syntactic re- strictions, case-role expectations, and most importantly, contextual effects. Compositional syntactic structure from a (...) shallow parsing is represented in a neural net-based associative memory, where it then interacts through a Bayesian network with semantic associa- tions and the context or “gist” of the passage carried forward from preceding sentences. Experiments with more than 2000 sentences in different languages are included. (shrink)

Ethical issues related to comparative effectiveness research, or research that compares existing standards of care, have recently received considerable attention. In this paper we focus on how Ethics Review Committees should evaluate the risks of comparative effectiveness research. We discuss what has been a prominent focus in the debate about comparative effectiveness research, namely that it is justified when “nothing is known” about the comparative effectiveness of the available alternatives. We argue that this focus may be misleading. Rather, we should (...) focus on the fact that some experts believe that the evidence points in favor of one intervention, whereas other experts believe that the evidence favors the alternative. We will then introduce a case that illustrates this point, and based on that, discuss how ERCs should deal with such cases of expert disagreement. We argue that ERCs have a duty to assess the range of expert opinions and based on that assessment arrive at a risk judgment about the study under consideration. We also argue that assessment of expert disagreement is important for the assignment of risk level to a clinical trial: what is the basis for expert opinions, how strong is the evidence appealed to by various experts, and how can clinical trial monitoring affect the possible increased risk of clinical trial participation.

Neurotrophins (NTs) are {?AUTHOR} a family of structurally related, secreted proteins that regulate the survival, differentiation and maintenance of function of different populations of peripheral and central neurons.1,2 Among these, BDNF (brain‐derived neurotrophic factor) has drawn considerable interest because both its synthesis and secretion are increased by physiological levels of activity, indicating a unique role of this neurotrophin in coupling neuronal activity to structural and functional properties of neuronal circuits. In addition to its classical neurotrophic effects, which are evident within (...) hours or days and which usually result from changes in cellular gene expression, BDNF exerts acute effects on synaptic transmission and is involved in the induction of long‐term potentiation. Many of these rapid effects of BDNF are mediated by its modulation of ion channel properties following TrkB‐mediated activation of intracellular second messenger cascades and protein phosphorylation. However, recent reports have shown that BDNF not only acts as a modulator of ion channels, but can also directly and rapidly gate a Na+ channel, thereby assigning BDNF the properties of a classical excitatory transmitter. Thus, BDNF, in addition its role as a potent neuromodulator, emerges as an excitatory transmitter‐like substance which acutely controls resting membrane potential, neuronal excitability, synaptic transmission and participates in the induction of synaptic plasticity.

Die Vermittlung ethischer Kompetenzen ist wesentlicher Bestandteil in berufsqualifizierenden und postgraduellen Studiengängen. Dabei werden praktisch-ethische Problemlösungskompetenzen, je nach Studiengang aber auch die forschungsethische Betrachtung von Studien thematisiert. Die Überprüfung dieser ethischen Kompetenzen stellt sich als Herausforderung dar. Das schriftliche oder mündliche Abfragen von Lehrinhalten greift zu kurz, da somit lediglich Wissen, jedoch nicht Fertigkeiten oder gar Haltung erfasst werden können.Bei der Reakkreditierung des Masterstudiengangs Pflegewissenschaft an der Universität Witten/Herdecke wurde dieser Herausforderung mit der Umsetzung eines für die postgraduelle Ausbildung innovativen (...) Prüfungsformats begegnet. Für das Modul „Ethik in der Pflegepraxis und -forschung“ wurde ein Format ausgearbeitet, welches sich an den „Objective Structured Clinical Examinations“ orientiert und somit die erworbenen Fertigkeiten und Haltungen der Studierenden mit einbezieht. Der Beitrag zeigt auf, wie das OSCE-Prüfungsformat konzipiert und eine Adaption erfolgt ist. (shrink)

Background Teaching ethical competencies is an essential component of professional and postgraduate curricula. Developing practical–ethical problem-solving competencies as well as appraising program-specific studies and related research ethics are topics typically addressed. However, assessment of these ethical competencies poses a challenge. Written or oral assessment formats addressing relevant learning objectives is mainly limited to knowledge testing alone, often not capturing relevant skills or attitudes pertinent to those competencies. Aim During the reaccreditation of the masters of science program in Nursing Science at (...) Witten/Herdecke University, this challenge was addressed by implementation of an innovative examination format for postgraduate education. Procedure For the module “Ethics in nursing practice and research” a format based on the Objective Structured Clinical Examination format was developed. This assessment method incorporates evaluation of acquired skills and attitudes of nursing students. Conclusion The article demonstrates development and adaption of the OSCE format for this purpose.

Trolling—the online exploitation of website, chat, or game mechanics at another user's expense—can and does take place all over cyberspace. It can take myriad forms, as well—some verbal, like trash-talking an opponent in a game, and some silent, like refusing to include a new player in a team effort during an in-game quest. However, despite this variety, there are few to no studies comparing the effects of these differing trolling types on victims. In addition, no study has yet taken into (...) account users' offline cultural context and norms into the trolling victim experience. To fill this gap in the literature, the present study put participants from three culturally-distinct countries—Pakistan, Taiwan, and the Netherlands—in a simulated trolling interaction using the Cyberball game. Participants were either flamed or ostracized by a member of their own cultural group or a minority member, and the participants' emotional responses, behavioral intentions toward the other players, and messages sent during the game were taken as indicators of their response to the trolling. Results showed that our Taiwanese sample used the most reactive aggression when trolled and our Dutch sample was the most passive. In addition, ostracism generally produced the desire to repair relationships, irrespective of cultural context, and perpetrator culture only produced an effect in the behavioral intentions of our Pakistani sample. Overall, it would appear that online and offline culture interact to produce the variety of responses to trolling seen in extant literature. Additional implications for future research into computer-mediated communication and online aggression are also discussed. (shrink)

Over recent years, the issue of corruption in the public construction sector has attracted increasing attention from both practitioners and researchers worldwide. However, limited efforts are available for investigating the underlying factors of corruption in this sector. Thus, this study attempted to bridge this knowledge gap by exploring the underlying factors of corruption in the public construction sector of China. To achieve this goal, a total of 14 structured interviews were first carried out, and a questionnaire survey was then administered (...) to 188 professionals in China. Two iterations of multivariate analysis approaches, namely, stepwise multiple regression analysis and partial least squares structural equation modeling were successively utilized to analyze the collected data. In addition, a case study was also conducted to triangulate the findings obtained from the statistical analysis. The results generated from these three research methods achieve the same conclusion: the most influential underlying factor leading to corruption was immorality, followed by opacity, unfairness, procedural violation, and contractual violation. This study has contributed to the body of knowledge by exploring the properties of corruption in the public construction sector. The findings from this study are also valuable to the construction authorities as they can assist in developing more effective anti-corruption strategies. (shrink)

This paper investigates the determinants of cost-(in)effective giving to public goods. We conduct a pre-registered experiment to elucidate how factors at the institutional and individual levels shape individual contributions and the cost-effectiveness of those contributions in a novel public good game. In particular, we examine the role of consequential uncertainty over the value of public good contributions (institutional level) as well as individual characteristics like risk and ambiguity attitudes, giving type, and demographics (individual level). We find cost-ineffective contributions in all (...) institutions, but total contribution levels and the degree of cost-ineffectiveness are similar across institutions. Meanwhile, cost-effectiveness varies by giving type—which is a novel result that is consistent with hypotheses we generate from theory—but other individual characteristics have little influence on the cost-effectiveness of contributions. Our work has important positive and normative implications for charitable giving and public good provision in the real world, and it is particularly germane to emerging online crowdfunding and patronage platforms that confront users with a multitude of competing opportunities for giving.

This research study sought to identify and categorize international marketing ethical problems that confront business managers in Australia and Canada. The study focused on ten major ethical problems developed from previous exploratory research. Managers from both countries indicate that the most frequently cited ethical problem is "gifts/ favors/entertainment" and the most important ethical problem is "large-scale bribery". However, there exist significant differences in terms of rankings and mean values of frequency and importance ratings for other ethical problems.

New fetal therapies offer important prospects for improving health. However, having to consider both the fetus and the pregnant woman makes the risk–benefit analysis of fetal therapy trials challenging. Regulatory guidance is limited, and proposed ethical frameworks are overly restrictive or permissive. We propose a new ethical framework for fetal therapy research. First, we argue that considering only biomedical benefits fails to capture all relevant interests. Thus, we endorse expanding the considered benefits to include evidence-based psychosocial effects of fetal therapies. (...) Second, we reject the commonly proposed categorical risk and/or benefit thresholds for assessing fetal therapy research. Instead, we propose that the individual risks for the pregnant woman and the fetus should be justified by the benefits for them and the study’s social value. Studies that meet this overall proportionality criterion but have mildly unfavorable risk–benefit ratios for pregnant women and/or fetuses may be acceptable. (shrink)
