AbstractFrequent claims that publics ‘misunderstand’ science ignore the contested definition of scientific uncertainty itself. Scientific uncertainty means different things in the natural sciences, social sciences and the humanities, while public controversies show that interpretations of scientific uncertainty have different implications for policy and decision-making. This prompts analysis of the ways that experts view scientific uncertainty and how they characterise the (mis)understandings of this uncertainty by policy-makers, media and publics. Experts from diverse academic fields define scientific uncertainty differently depending on their disciplinary background. For example, mathematics provides experts from the natural sciences with a practice language that facilitates communication with those sharing this cultural competence, but it does not suffice for engaging with wider audiences. Further, experts’ views of diverse publics come across as folk theories, in Arie Rip's terms, which, compiled from disparate pieces of information, can be used to fill a gap in the knowledge about publics. 相似文献

The purpose of the study was to investigate the effect of changes on work motivation and the effect of the changes on future mental well-being. This prospective study comprised 577 employees who were followed up 18 months after a comprehensive baseline measurement. The response rate was 81% for the baseline and 72% for the follow-up. The results show that both negative and positive changes in work motivation over time (18 months) were related to exhaustion. A similar correlation was found between negative changes in work motivation and depression. The results show that employees with a decreased level of work motivation had a higher risk of experiencing more exhaustion and depression in the future. Thus, investing in activities to promote work motivation may be an effective means of preventing long-term sick leave for stress-related mental illness and of providing energy for successful career advancement. 相似文献

Gift-for-sex (GFS) barters are a niche practice potentially representing the commodification of everyday dating practices. We inquire how GFS exchanges are practiced and understood in contemporary Russia. Second, we situate these in relation to contemporary economic culture. Our project provides answers in two steps based on online content. First, we identify GFS exchange practices within a major dating website. Next, we take the signals exchanged in those dating profiles and display their intersubjective meanings in Russia based on blogs and discussion fora. Our analysis focuses on gender roles and inter-gender conflicts, the use of economic jargon, the link between luxury consumption and sexuality, and understandings of gift-giving and generosity, in order to show how GFS barters, despite being contractual, carry emotional and romantic content. As such, love is under a constant conversion process, through the medium of the contractual gift, into the fictitious commodity form. 相似文献

The mental model theory predicts that reasoners normally represent what is true, but not what is false. One consequence is that reasoners should make “illusory” inferences, which are compelling but invalid. Three experiments confirmed the existence of such illusions based on disjunctions of disjunctions. They also established a successful antidote to them: Reasoners are much less likely to succumb to illusions if the inferences concern disjunctions of physical objects (alternative newspaper advertisements) rather disjunctions of the truth values of assertions. The results shed light both on the cause of the illusions and on the current controversy among different theories of reasoning. 相似文献

Incidence rates of third party workplace violence in Europe have increased, but little is known about the causes thereof. It has been suggested that the growth of the service sector and the intensification of work could be responsible for the increase. This study aimed to identify trends in the prevalence of physical workplace violence across Europe, as well as to uncover factors explaining these trends. Three cross-sectional waves (1995, 2000, and 2005) of the European Working Conditions Survey were used, involving 58,520 workers and covering 15 European member states. Logistic regression analyses were performed to investigate associations between work characteristics and violence prevalence. Workplace violence increased significantly during the study interval. Although violence was clearly related to specific characteristics of the labour market (gender, age, sector, etc.) and the work environment (client contact frequency, time pressure, control, and computer work), recent changes in the European labour market composition and work environment could not explain the increase in violence. In jobs characterized by high levels of computer work in particular, violence appears to be an emerging risk. Our results suggest that the nature (and perhaps quality) of client contact is changing, leading to higher violence risks. 相似文献

In primates and adult humans direct understanding of others' action is provided by mirror mechanisms matching action observation and action execution (e.g. Casile, Caggiano & Ferrari, 2011). Despite the growing body of evidence detailing the existence of these mechanisms in the adult human brain, their origins and early development are largely unknown. In this study, for the first time, electromyographic (EMG) measures were used to shed light on the emergence of mirror motor mechanisms in infancy. EMG activity was recorded while 6‐ and 3‐month‐old infants watched two videos displaying an agent reaching for, grasping and bringing an object either to the mouth or to the head. Results indicate that the motor system of 6‐month‐olds, but not 3‐month‐olds, was recruited and selectively modulated during observation of the goal‐directed actions, favoring the idea that mirror mechanisms driving action understanding gradually emerge during early development. 相似文献

The 1997 discovery of free fetal DNA in maternal plasma launched clinical researchers’ efforts to establish a reliable method for non-invasive prenatal testing for fetal genetic conditions. Various methods, including, but not limited to, massively parallel sequencing (MPS) and selective analysis of cell-free fetal DNA in maternal plasma, have recently been developed as highly sensitive and specific noninvasive screening tools for common fetal chromosome aneuploidies. Incorporating these new noninvasive technologies into clinical practice will impact the current prenatal screening paradigm for fetal aneuploidy, in which genetic counseling plays an integral role. The National Society of Genetic Counselors (NSGC) currently supports Noninvasive Prenatal Testing/Noninvasive Prenatal Diagnosis (NIPT/NIPD) as an option for patients whose pregnancies are considered to be at an increased risk for certain chromosome abnormalities. NSGC urges that NIPT/NIPD only be offered in the context of informed consent, education, and counseling by a qualified provider, such as a certified genetic counselor. Patients whose NIPT/NIPD results are abnormal, or who have other factors suggestive of a chromosome abnormality, should receive genetic counseling and be given the option of standard confirmatory diagnostic testing. 相似文献

According to Aristotle, the most characteristic activity of friendship is “living together” [to suzên]. This paper seeks to understand living together in the light of his famous, foundational claim that humans are social by nature. Based on an interpretation of Nicomachean Ethics 9.9, I explain our need for friends in terms of a more fundamental human need to appreciate one's life as a whole. I then argue that friendship is built into the very structure of human life itself such that human living is living together. 相似文献

Feeling Controlled and Drinking Motives Among College Students: Contingent Self-Esteem as a Mediator
Clayton Neighbors Mary E Larimer Irene Markman Geisner C Raymond Knee 《Self and identity》2013,12(3):207-224
This article presents an examination of college student drinking motives from a self-determination perspective. We predicted positive associations between controlled orientation (a chronic orientation toward pressures and experiencing a lack of choice in one's behaviors), and drinking as a means of regulating affect (enhancement and coping motives) and social approval (social rewards and conformity motives). Contingent self-esteem involves deriving self-worth from meeting expectations and was expected to mediate the relation between controlled orientation and drinking motives, which were in turn expected to predict alcohol consumption and related consequences. College students' (N?=?204) controlled orientation, contingent self-esteem, motives for drinking, and patterns of alcohol use were assessed. Mediation analyses provided support for our theoretical framework. Results suggest that “controlled” individuals drink to regulate affect and social approval in part because they have a greater tendency to base self-worth on contingencies. 相似文献
