Focused ultrasound therapy (FUS) is a modern and promising way for minimally invasive cancer treatment. Recent advances in treatment technology, bio‐physical models, and numerical simulation methods have given rise to a significant curative potential. However, clinical routine of FUS still features classical planning approaches, which widely fail in exploiting this potential. The structure of FUS planning problems strongly suggests interactive multi‐criteria decision‐making concepts in order to improve treatment quality. This research work introduces an multi‐criteria decision‐making approach to FUS planning and explains how to bridge the conceptual gap between the clinical state of the art and this new planning paradigm. 相似文献

Research on human navigation has indicated that males and females differ in self-reported navigation strategy as well as objective measures of navigation efficiency. In two experiments, we investigated sex differences in navigation strategy and efficiency using an objective measure of strategy, the dual-solution paradigm (DSP; Marchette, Bakker, & Shelton, 2011). Although navigation by shortcuts and learned routes were the primary strategies used in both experiments, as in previous research on the DSP, individuals also utilized route reversals and sometimes found the goal location as a result of wandering. Importantly, sex differences were found in measures of both route selection and navigation efficiency. In particular, males were more likely to take shortcuts and reached their goal location faster than females, while females were more likely to follow learned routes and wander. Self-report measures of strategy were only weakly correlated with objective measures of strategy, casting doubt on their usefulness. This research indicates that the sex difference in navigation efficiency is large, and only partially related to an individual’s navigation strategy as measured by the dual-solution paradigm. 相似文献

Republican Voters Prefer Candidates Who Have Conservative‐Looking Faces: New Evidence From Exit Polls 下载免费PDF全文
Research shows people share common political facial stereotypes: They associate faces with political ideologies. Moreover, given that many voters rely on party affiliation, political ideology, and appearances to select political candidates, we might expect that political facial stereotypes would sway voting preferences and, by extension, the share of votes going to each candidate in an election. And yet few studies have examined whether having a stereotypically conservative‐looking (or liberal‐looking) face predicts a candidate's vote shares. Using data from U.S. election exit polls, we show that the Republican voters within each state are more likely to vote for a candidate (even a Democrat) the more that person has a stereotypically Republican‐looking face. By contrast, the voting choices of the Democratic voters within each state are unrelated to political facial stereotypes. Moreover, we show that the relationship between political facial stereotypes and voting does not depend on state‐level ideology: Republican voters in both right‐leaning (“red”) and left‐leaning (“blue”) states are more likely to vote for candidates with conservative‐looking faces. These results have several important practical and theoretical implications concerning the nature and impact of political facial stereotypes, which we discuss. 相似文献

Eating disorders and subclinical behaviours such as dangerous dieting are a significant public health burden in the modern world. We argue that a social-psychological model of disordered eating is needed to explain how sociocultural factors are psychologically represented and subsequently reflected in an individual’s cognitions and behaviour. We present evidence that three central elements shape disordered eating – social norms, social identity and social context – and integrate these within a Situated Identity Enactment (SIE) model. Specifically, the SIE model states that social context determines the salience of both social norms and social identities. Social norms then influence disordered eating behaviour, but only to the extent that they are consistent represented in the content of a person’s social identities. We conclude by outlining the implications of the SIE model for researchers and practitioners in the domain of disordered eating, focusing in particular on the need for, and potential value of, theory-derived social interventions. 相似文献

Bas C. van Fraassen, in his Terry Lectures at Yale University (subsequently published as The Empirical Stance), is concerned to elucidate what empiricism is, and could be, given past and current failures of characterization. He contends that naïve empiricism—the metaphilosophical position that characterizes empiricism in terms of a thesis—is self‐refuting, and he offers a reductio ad absurdum to substantiate this claim. Moreover, in place of naïve empiricism, van Fraassen endorses stance empiricism: the metaphilosophical position that characterizes empiricism in terms of certain attitudes and commitments. The present article, however, argues that van Fraassen begs the question in his reductio of naïve empiricism, and thus that his primary defense of stance empiricism is inadequate. 相似文献

The paper examines “Campbell’s Law”: “The more any quantitative social indicator is used for social decision-making, the more subject it will be to corruption pressures and the more apt it will be to distort and corrupt the social processes it is intended to monitor.” The examination of measurability leads to explaining the reason for existence of a class of unmeasurable phenomena. The author describes a kind of habitus in which a strong taboo against measuring must exist by necessity, not by choice. The taboo is, in effect, a result of degradation of a certain kind of habitus. And finally, the paper demonstrates under which conditions the Campbell’s law is in effect, and how we can mitigate its effects in social decision-making. 相似文献

Although self-determination theory (SDT) is one of the most widely cited theories of human motivation and function, critics have questioned the practical utility of its three needs (i.e., autonomy, competence, and relatedness) in performance contexts. We conduct a meta-analysis (k = 108, N = 30,648) to explore the magnitude and boundary conditions of need satisfaction and performance. As expected, autonomy (ρ = .28), competence (ρ = .37), and relatedness (ρ = .25) predict performance. Incentivization per se has little impact on need-satisfaction: instead, the need satisfaction → performance relationship is moderated by incentive salience. Consistent with a crowding-out hypothesis, need satisfaction matters less to performance when incentives are directly salient (ρ = .22) and more when indirectly salient (ρ = .45). Our meta-analysis demonstrates that indirectly salient incentives and need-satisfaction are indeed compatible, providing a direct response to criticisms of SDT in performance contexts. Additional unexpected findings and future directions are discussed. 相似文献

There is a widespread consensus regarding the importance of self-control for various personal and social issues. However, the concept itself remains elusive, with numerous definitions and operational measurements competing. This article proposes a widely applicable statistical framework. Most theories propose that multiple, usually two, latent processes affect self-control. Mixture models can estimate to what extent hypothesized processes explain choice data. They also allow measuring how various dispositional and situational variables affect the relative contribution of each process considered. The approach promises to help seizing the concept of self-control, testing competing theories, and clarifying the effect of various variables. 相似文献

Successful cooperation requires that humans can flexibly adjust choices to their partner’s behaviour. This, in turn, presupposes a representation of a partner’s past decisions in working memory. The aim of the current study was to investigate the role of working memory processes in cooperation. For that purpose, we tested the effects of working memory updating (Experiment 1) and working memory maintenance demands (Experiments 2 and 3) on cooperative behaviour in the Prisoner’s dilemma game. We found that demands on updating, but not maintenance, of working memory contents impaired strategy use in the Prisoner’s dilemma. Thus, our data show that updating a partner’s past behaviour in working memory represents an important precondition for strategy use in cooperation. 相似文献
