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 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.

The objective of this study is to evaluate if use of a patient decision aid, when choosing between a repeat cesarean or a trial of labor after a cesarean, reduces medical liability exposure. The authors conclude that use of a PDA conferred liability protection when potential jurors were presented with a hypothetical malpractice claim against an obstetrician following a TOLAC.

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.

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)

concepts like numbers or time are thought to be represented in the more concrete domain of space and the sensorimotor system. For example, thinking of past or future events has a physical manifestation in backward or forward body sway, respectively. In the present study, we investigated the reverse effect: can passive whole-body motion influence the processing of temporal information? Participants were asked to categorize verbal stimuli to the concepts future or past while they were displaced forward and backward , or (...) upward and downward . The results showed that future related verbal stimuli were categorized faster during forward as compared to backward motion. This finding supports the view that temporal events are represented along a mental time line and that the sensorimotor system is linked to that representation. We showed that body motion is not just an epiphenomenon of temporal thoughts. Passive whole-body motion can influence higher-order temporal cognition. (shrink)

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)

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.

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)

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)

People often make use of a spatial “mental time line” to represent events in time. We investigated whether the eyes follow such a mental time line during online language comprehension of sentences that refer to the past, present, and future. Participants' eye movements were measured on a blank screen while they listened to these sentences. Saccade direction revealed that the future is mapped higher up in space than the past. Moreover, fewer saccades were made when two events are simultaneously taking (...) place at the present moment compared to two events that are happening in different points in time. This is the first evidence that oculomotor correlates reflect mental looking along an abstract invisible time line during online language comprehension about time. Our results support the idea that observing eye movements is likely to “detect” invisible spatial scaffoldings which are involved in cognitively processing abstract meaning, even when the abstract meaning lacks an explicit spatial correlate. Theoretical implications of these findings are discussed. (shrink)

Der umfassende Prozess der weltweiten Digitalisierung prägt alle gesellschaftlichen Systeme in unterschiedlicher Weise. Wie sehr verändert die Digitalisierung die uns bekannte Welt und die Vulnerabilität des Lebens? Sind die damit verbundenen Transformationen gar wünschenswert und/oder notwendig? In Hinblick auf eine Vergewisserung dessen, was als (unsere) Welt anzusehen ist, bietet sich der Begriff der Lebenswelt im Ausgang von Edmund Husserl an. Demnach ist es eine wirklich anschauliche, wirklich erfahrene und erfahrbare Welt, in der sich unser ganzes Leben praktisch abspielt. Technisierung bedeutet (...) eine Veränderung dieses menschlichen Weltverhältnisses. Husserl attestierte seinerzeit eine Lebensweltvergessenheit, die zu einer Krise Europas und des europäischen Menschentums beitragen würde. Daher setzte er sich für eine Rehabilitierung der Lebenswelt als Sinnesfundament ein. Diese berühmte Diagnose und jene Massnahme sind seit Husserls Tagen immer wieder aufgegriffen worden. Wird die Digitalisierung die Welt in eine komplett künstliche Welt transformieren, die den Zusammenhang von persönlicher Erfahrung, Leiblichkeit, gesellschaftlichen Institutionen und Erscheinungen der Natur aufgekündigt hat? Bevor eine solche Befürchtung geglaubt werden kann, gilt es, grundlegende Muster der Digitalisierung im Hinblick auf ihre lebensweltliche Konkretion zu befragen. Die vorliegende Studie untersucht Prozesse und deren Querverbindungen aus den Bereichen Politik, Wirtschaft, Verkehr, Wissen, Bildung, Literatur, Gesundheit und Erotik. (shrink)

The underrepresentation of females in mathematics-related fields may be explained by gender differences in mathematics self-concept (rather than ability) favoring males. Mathematics self-concept typically declines with student age, differs with student ethnicity, and is sensitive to teacher influence in early schooling. We investigated whether change in mathematics self-concept occurred within the context of a longitudinal intervention to raise and sustain teacher expectations of student achievement. This experimental study was conducted with a large sample of New Zealand primary school students and (...) their teachers. Data were analyzed using longitudinal multilevel modelling with mathematics self-concept as the dependent variable and time (which represents students’ increasing age each year), gender, and ethnicity entered as predictors and achievement in mathematics included as a control variable. Interaction terms were also explored to investigate changes over time for different groups. All students demonstrated a small increase in mathematics self-concept over the three-year period of the current study but mathematics self-concept was consistently greater for boys than girls. Māori, Asian, and Other students’ initial mathematics self-concept was higher than that of New Zealand European and Pacific Islanders’ (after controlling for achievement differences). However, a statistically significant decline in mathematics self-concept occurred for Māori students alone by the end of the study. The expected age-related reduction over time in student mathematics self-concept appeared to be mitigated in association with the longitudinal study. Nevertheless, the demonstration of a comparatively lower mathematics self-concept remained for girls overall and declined for Māori. Our results reinforce implications for future research into mathematics self-concept as a possible determinant of female student career choices. (shrink)

Reality has become an increasingly prominent topic in contemporary philosophy. The book’s contributors are responding to the challenge to use the philosophically underexplored potential of film to disclose what the editors propose to call “the real of reality.”.

In March 2003, President Bush declared the start of Operation Iraqi Freedom, the anticipated commencement of intensive American-led military operations in Iraq. With this declaration, the media began intense coverage of military operations from the field. For the first time, viewers were able to see images of actual events. This was due to three developments: the advancement of technology allowing immediate transmission of text and images, the actual presence of journalists identified as "embedded journalists" at military sites, and the fierce (...) competition among networks for viewers. One result of this constant coverage was significant pressure on decision makers within the television and cable news networks to decide within a matter of seconds which images to air. In particular, producers and broadcasters of competing networks experienced this pressure. Though the radio and broadcasting industry has a published code of standards, it is "general and advisory rather than specific and restrictive." Therefore, it did not address the unique time sensitive decision-making required within this new environment. Issues such as the security of soldiers, confidentiality of troop maneuvers, and the safety of the embedded journalists were critically important. Equally serious were the concerns about the impact of the immediate airing of information and violent images to the public. This research used Patrick Primeaux's ' mind-heart-sou¾ model of decision-making as its theoretical framework. The study investigated the gender and industry experience of selected professionals in a cable news network, MSNBC, to explore how ethical codes of behavior are integrated when people make decisions. Decision-making in both their professional and personal lives was examined. It is from this perspective that their professional decisions to air/not to air material from Operation Iraqi Freedom were studied. The findings on decisions about airing/not airing material from Operation Iraqi Freedom yielded both expected and unexpected results. There was no clear gender difference regarding ethical decision-making, but there was a difference when analyzed by industry experience. When the study focused on questions regarding the respondents' personal lives, the original hypothesis that there was a gender difference was validated. (shrink)
