The spread of the COVID-19 pandemic quickly necessitated digital learning, which bore challenges for all pupils but especially for groups disadvantaged in a virtual classroom. As some studies indicate persistent differences between boys and girls in use of technologies and related skills, the aim of this study was to investigate gender differences in the digital learning environment students faced in spring 2020. Previous studies investigating gender differences in digital learning largely used biological sex as the only indicator of gender. This (...) study includes both biological sex and gender role self-concept in order to investigate the role of gender in different components of this stereotyped domain in a more differentiated way. A total of 19,190 Austrian secondary school students participated in an online study in April 2020 and answered questions regarding their competence beliefs, intrinsic value, engagement, and perceived teacher support in digital learning during the pandemic-induced school closures. Results showed higher perceived teacher support, intrinsic value, and learning engagement among girls than boys, while no significant sex differences were found in competence beliefs regarding digital learning. Furthermore, our results indicated clear benefits of an androgynous gender role self-concept for all studied components of digital learning. Implications of the findings for theory and practice are discussed. (shrink)

The cytokine interferon‐γ (IFN‐γ), initiates both cell cycle arrest and cell death in certain cell lines. Through a novel strategy of cell transfection with episomal vectors expressing antisense cDNAs, Deiss et al.(1.2) have demonstrated that it is possible to isolate genes that are required for the initiation of cell death by the cytokine IFN‐γ. This approach, referred to as TKO, for Technical Knock Out, has identified several genes whose activity appears to be essential for the induction of apoptosis by IFN‐γ (...) in HeLa cells. Interestingly, these genes appear to mediate IFN‐γ‐induced apoptosis in HeLa cells, but their inhibition by antisense does not ameliorate the anti‐proliferative effects of IFN‐γ in these cells. The clever strategy employed by these authors holds promise for others who wish to isolate genes required for other differentiative processes in cultured cell lines. (shrink)

The pessimistic conclusion that people have relatively poor insight into the weighting schemes they use when they make holistic judgements has been generally accepted among judgement researchers. The empirical research that supported this generalisation rested on indices of self-insight that were produced directly by the subjects. It was often the case that subjects were unable to correctly name even the single most important factor influencing their decisions, as indicated by a mathematical model of their judgement schemes. Using an alternate method (...) of assessing self-insight, however, Reilly and Doherty found that subjects have far better self-insight than previously believed possible. The present paper employed the same methodology to investigate insight into the policy of another person as well as into oneself, and examined the relation of self-insight and other-insight to interpersonal conflict. Subjects were 50 dyads of university students. The results showed that: subjects exhibited the expected high levels of self-insight via the recognition procedure; subjects were able to identify the statistically generated policy of their roommate, thus exhibiting other-insight; the ability to identify one's own policy is somewhat related to the ability to articulate one's own policy that is, roommates with insight via recognition had higher indices of self-insight as measured by the traditional correlation method; subjects who were able to identify their own policy were more likely to identify their roommate's policy and individuals who possess self- and other-insight had less conflict in their roommate relationships.

When base rates are learned and used in an experiential manner subjects show better base rate use, perhaps because the implicit learning system is engaged. A causal framework in which base rates are relevant might also be necessary. Humans might thus perform better on more ecologically valid tasks, which are likely to contain those three components.

Der Vergleich einer modernen Rechts- und Gesellschaftstheorie anhand von Hayeks «Recht, Gesetz und Freiheit» mit einer postmodernen anhand Ladeurs «Der Staat gegen die Gesellschaft» fördert verblüffende Parallelen im Ausgangspunkt, der Argumentation und der Prognose respektive Diagnose einer institutionell bedingten postmodernen Krise von Staat und Gesellschaft zutage. Die Analyse der modernen Theorie ist zugleich eine umfassende und verständliche Einführung in von Hayeks Werk. Fundiert arbeitet die Schrift die Theorie als die in der Moderne gelegte Basis der postmodernen Gesellschaft heraus und gleicht (...) sie ab mit den Untersuchungen Ladeurs zur Postmoderne in dessen Streitschrift für die «Privatrechtsgesellschaft». Anknüpfend an den von beiden analog begründeten Weg in die Krise und die Wege zu ihrer Bewältigung zeigt die Autorin eine über diese Zeitspanne hinaus weisende kongruente liberale rechts-, staats- und gesellschaftspolitische Theorie auf.

The purpose of this paper is to examine the various guidelines presented in the literature for instituting an ethics curriculum and to empirically study their effectiveness. Three questions are addressed concerning the trainability of ethics material and the proper integration and implementation of an ethics curriculum. An empirical study then tested the effect of ethics training on moral awareness and reasoning. The sample consisted of two business classes, one exposed to additional ethics curriculum (experimental), and one not exposed (control). For (...) the experimental group, ethics exercises and discussion relevant to each topic were completed. Findings suggested gender differences such that, relative to other groups, women in the experimental group showed significantly improved moral awareness and decision-making processes. An explanation of the underlying cognitive processes is presented to explain the gender effect. (shrink)

Paul Appelbaum and colleagues propose four models of informed consent to research that deploys whole genome sequencing and may generate incidental findings. They base their analysis on empirical data that suggests that research participants want to be offered incidental findings and on a normative consensus that researchers incur a duty to offer them. Their models will contribute to the heated policy debate about return of incidental findings. But in my view, they do not ask the foundational question, In the context (...) of genome sequencing, how much work can consent be asked to do? (shrink)

Children deserve optimal medical care. Although prescription drugs play a prominent and essential role in pediatric health care delivery, health care providers often must make prescribing decisions for their young patients based on imperfect or absent safety and efficacy data for pediatric populations. Until relatively recently, the Food and Drug Administration made surprisingly little effort to improve the quality or quantity of clinical research data for this patient group. Despite recent agency efforts to improve the situation, only one-third of drugs (...) prescribed to children currently have been studied for safety and efficacy in pediatric populations. Moreover, recent agency initiatives to encourage pediatric drug research have generated mixed results and unintended consequences. The complex of issues surrounding the testing and prescribing of prescription drugs used for children will require that pharmaceutical companies, the FDA, and health care providers examine current practices, acknowledge their shortcomings, and consider cooperative, creative solutions.

Taking the possibility of visual argumentation seriously, this essay explores how refutation might proceed. We posit three ways in which images can refute and be refuted in a mixed-media environment: (1) dissection, in which an image is broken down discursively; (2) substitution, in which one image is replaced within a larger visual frame by a different image; and (3) transformation, in which an image is recontextualized in a new visual frame. These strategies are illustrated in an analysis of three American (...) documentary films on abortion. (shrink)

The theme of this special issue is Post-truth. No doubt it was my exasperation with the terminological state of our collective situation that incited me in the spring of 2017 to settle upon it. What, exactly, does the hyphenated couplet mean or to what does it refer? What is its significance or sense? How is it being used, by whom, for what purpose, and with what consequences—for whom? And if, as was being asserted on nearly every side, we currently find (...) ourselves in post-truth, how might we ever get out, presuming we may one day want as much? The original contributions by Sarah Burgess, James Crosswhite, Jason David Myres, Bradford Vivian, and Eric King Watts published herein go a long way toward answering these... (shrink)

Creativity and civil courage are major dimensions of an intellectual's authority and contribute towards the enrichment of democracy. This book develops a sociological account of civil courage and creative behaviour in order to enhance our understanding of the nature of intellectuals' involvement in society. Barbara A. Misztal employs both theoretical-analytic and empirical components to develop a typology of intellectuals who have shown civil courage and examines the biographies of twelve Nobel Peace Prize laureates, including Elie Wiesel, Andrei Sakharov and (...) Linus C. Pauling, to illustrate acts of courage which have embodied the values of civil society. She advances our understanding of the nature of intellectuals' public involvement and their contribution to social well-being. In the current climate of fear and insecurity, as governments are forced to deal with issues of increasing complexity, this is a pioneering sociological book with a highly original approach.

SummaryCross-sectional studies in Australia and the Philippines and a longitudinal prospective study in a selected Australian sample of breast-feeding mothers have shown that basal serum prolactin concentrations are elevated during 15–21 months of lactational amenorrhoea.A predictive model of serum PRL levels and return of cyclic ovarian activity during full breast-feeding, partial breast-feeding and weaning has been developed from the results of breast-feeding behaviour and serum PRL, gonadotrophin and oestradiol measurements in 34 mothers breast-feeding on demand for a mean of 67 (...) weeks.Breast-feeding patterns influence serum PRL levels. Important factors during full breast-feeding are the age of the baby, the longest interval between feeds at night and total 24-hr suckling time, and following the introduction of supplements, the mean interval between feeds, together with the total 24-hr suckling time and the number of solid supplements per day.The precise mechanisms whereby breast-feeding regulates cyclic ovarian activity remain unknown. Gonadotrophin secretion appears to be quantitatively normal, but qualitative changes, secondary to altered hypothalamic activity, may be the most important factor. A direct inhibitory effect of PRL on ovarian follicular development and steroidogenesis remains possible.Ovulation with a normal luteal phase is probable for 30% of breast-feeding mothers before the first menses, but is unlikely before 6 months, provided breast-feeding is frequent day and night.Measurement of serum PRL is a sensitive index of the return of menstruation and fertility during lactation in the population studied.

This article explores risk in professional nursing practice. Professional risk refers to the threat of professional discipline if it is found that a registered nurse has violated professional nursing practice standards. We argue professional risk is socially constructed and understood differently by nurse regulatory bodies, unions, professional associations and frontline nurses. Regulatory bodies emphasize professional accountability of nurses; professional associations focus on system problems in health‐care; unions undertake protecting nurses' right to health and safety; and frontline nurses experience fear and (...) uncertainty in their attempt to interpret practice standards to avoid professional discipline. Perspectives of professional risk are investigated by analyzing three professional nursing bodies' views of professional codes governing the right of nurses to refuse unsafe work assignments. The workplace dynamics surrounding work refusal experienced by frontline nurses are illustrated primarily through the lens of the 2003 SARS influenza outbreak in Ontario, Canada. We conclude that frontline nurses in Ontario are required to manage risk by following professional protocols prioritizing patient care and professional accountability which disregard the systemic, unpredictable and hazardous circumstances in their everyday practice. Moreover, we argue professional protocols cannot anticipate every eventuality in clinical practice creating the fear of professional discipline for nurses. (shrink)

This study documents and characterizes a phenomenon in naturally‐occurring conversation which I have termed interactional reconstruction. Interactional reconstruction involves retroactive reinterpretation of an earlier utterance (or set of utterances) on the basis of a more recent utterance (or set of utterances). This work is meant to serve two functions: first, to enrich our theories of human communication; and second, to explore directions and implications for theories of meaning and discourse modeling within cognitive science.
