关注幽门螺杆菌治疗中的实际问题

我国对Hp感染诊断和治疗有自己的标准,也有很多成熟的经验,但在根除HP治疗过程中,存在诸多问题,如过度医疗、适应证掌握不严格、第一次根除失败后再次治疗不规范等。我们应共同关注这些问题,提高Hp根除率,降低治疗中的副作用,对HP的许多未知问题从不认识到认识。     

Structural equations modeling: Fit Indices,sample size,and advanced topics

This article is the second of two parts intended to serve as a primer for structural equations models for the behavioral researcher. The first article introduced the basics: the measurement model, the structural model, and the combined, full structural equations model. In this second article, advanced issues are addressed, including fit indices and sample size, moderators, longitudinal data, mediation, and so forth.     

Implementing Housing First Across Sites and Over Time: Later Fidelity and Implementation Evaluation of a Pan-Canadian Multi-site Housing First Program for Homeless People with Mental Illness

This article examines later fidelity and implementation of a five‐site pan‐Canadian Housing First research demonstration project. The average fidelity score across five Housing First domains and 10 programs was high in the first year of operation (3.47/4) and higher in the third year of operation (3.62/4). Qualitative interviews (36 key informant interviews and 17 focus groups) revealed that staff expertise, partnerships with other services, and leadership facilitated implementation, while staff turnover, rehousing participants, participant isolation, and limited vocational/educational supports impeded implementation. The findings shed light on important implementation “drivers” at the staff, program, and community levels.     

Physiological Arousal and Political Beliefs

It is by now well known that political attitudes can be affected by emotions. Most earlier studies have focused on emotions generated by some political event (e.g., terrorism or increased immigration). However, the methods used in previous efforts have made it difficult to untangle the various causal pathways that might link emotions to political beliefs. In contrast, we focus on emotions incidental (i.e., irrelevant) to the decision process, allowing us to cleanly trace and estimate the effect of experimentally induced anxiety on political beliefs. Further, we build upon innovative new work that links physiological reactivity (Hatemi, McDermott, Eaves, Kendler, & Neale, 2013; Oxley et al., 2008a) to attitudes by using skin conductance reactivity as a measure of emotional arousal. We found that anxiety—generated by a video stimulus—significantly affected physiological arousal as measured by tonic skin‐conductance levels, and that higher physiological reactivity predicted more anti‐immigration attitudes. We show that physiological reactivity mediated the relationship between anxiety and political attitudes.     

Interaction Between Phonological and Semantic Representations: Time Matters

Computational modeling and eye‐tracking were used to investigate how phonological and semantic information interact to influence the time course of spoken word recognition. We extended our recent models (Chen & Mirman, 2012; Mirman, Britt, & Chen, 2013) to account for new evidence that competition among phonological neighbors influences activation of semantically related concepts during spoken word recognition (Apfelbaum, Blumstein, & McMurray, 2011). The model made a novel prediction: Semantic input modulates the effect of phonological neighbors on target word processing, producing an approximately inverted‐U‐shaped pattern with a high phonological density advantage at an intermediate level of semantic input—in contrast to the typical disadvantage for high phonological density words in spoken word recognition. This prediction was confirmed with a new analysis of the Apfelbaum et al. data and in a visual world paradigm experiment with preview duration serving as a manipulation of strength of semantic input. These results are consistent with our previous claim that strongly active neighbors produce net inhibitory effects and weakly active neighbors produce net facilitative effects.     

Création et validation d’une version française du questionnaire AttrakDiff pour l’évaluation de l’expérience utilisateur des systèmes interactifs

IntroductionWhile user experience (UX) evaluation is a core concern within the field of human–computer interaction (HCI), there is currently no valid self-administered UX evaluation tool in French. The AttrakDiff 2 scale (Hassenzahl, Burmester, & Koller, 2003) is a UX evaluation tool, which relies on a theoretical model distinguishing pragmatic and hedonic qualities of interactive systems.ObjectiveThis paper describes the translation and validation of the French version of the AttrakDiff 2 scale in order to ease UX assessment in French-speaking users.MethodFollowing the cross-cultural methodology developed by Vallerand (1989), the questionnaire was translated by trilingual researchers before being back-translated and validated by a panel of experts. A pre-test was conducted on 26 participants. The characteristics of the French version of the AttrakDiff 2 scale were then evaluated through a quantitative online study involving a sample of 381 users.ResultsThe results confirm the expected 3 factors structure and a good internal consistency of each subscale. The links between factors are consistent with Hassenzahl's theoretical model (2003) where pragmatic and hedonic perceived attributes combine to form a judgment of attractiveness.ConclusionThe current French version of the AttrakDiff 2 scale is globally reliable with regards to the initial German version and presents satisfactory levels of validity and reliability.     

Assessing Mental Health Providers' Perceptions of Consumer-Providers

To gain insight into the challenges of the occupational role of consumer-provider, the authors describe a program evaluation that assessed mental health providers' perceptions of consumer-providers. A qualitative research design was used to assess non-consumer providers' attitudes toward and perceptions of consumer-providers, perceptions of the quality of services consumer-providers deliver, and knowledge and awareness of consumer-providers' education and training background. Four themes emerged, including: (1) service delivery, (2) comparisons between consumer-provided and non-consumer staff provided services, (3) perception and opinion of consumer-providers' education and training background, and (4) power dynamics. Implications of the findings are discussed.     

羞耻研究:概念、结构及其评定

近年来国内外心理学界有关羞耻的实证研究有了很大的进展,这在很大程度上归因于对羞耻概念本身的深入理解以及相应评定方法的发展。文章梳理了羞耻的概念、结构及其评定的已有研究成果,总结了国内外心理学界在以上三个领域的理论偏向、研究取向和评定范式,指出了已有研究中存在的困惑,最后提出了羞耻概念、结构及评定的未来研究要实现两个转向,一是从研究视角来看,由结构和类型视角转向关系和情境视角,二是从评定范式来看,由西方实证研究范式转向本土研究范式。     

神经递质认识过程的哲学思考

神经递质的认识过程是一个复杂的过程。在此过程中产生和抛弃过许多假说，但新的理论仍在不断发展。这样的过程给予了我们许多哲学启示。
