从两种技术的差异看中医技术主体化的困境

经验技术与科学技术在来源、本质与发展规律上存在着诸多差异.中医技术具有模仿自然性,个体技能性和发展渐进性特点,总体上属于经验技术.经验技术与科学技术内在差异导致了中医经验技术在科学化过程遭遇种种困境.现代科技占据中医技术主体不仅消解了中医学的自然性与人文性,最终也将导致整个中医体系的消解.     

A Review of “Suicidal Intent” Within the Existing Suicide Literature

The results of a systematic literature review that investigated suicide intent are presented. Of the 44 relevant articles identified, 17 investigated the relationships between various suicide risk factors and suicide intent and 25 publications investigated the relationships between suicide intent and various suicide outcomes. Despite recent advancements in the definition and nomological validity of suicide intent, a high degree of variability in the empirical measurement and analysis of suicide intent was found. Such variability limits future research related to measuring suicidal risk and outcomes, reporting suicide intent, or the meaningful comparison of diagnostic approaches or treatments across multiple studies.     

Coparenting Experiences in African American Families: An Examination of Single Mothers and their Nonmarital Coparents

African American youth from single‐mother homes continue to be overrepresented in statistics on risk behavior and delinquency, a trend that many be attributed to father‐absence, socioeconomic disadvantage, and compromises in parenting more typical of single than two‐parent families. Yet, this risk‐focused perspective ignores a long‐standing strength of the African American community, the involvement and potential protective impact of extended family members in childrearing. This study describes the experiences of 95 African American single mothers and their nonmarital coparents who participated in a study of African American single‐mother families with an 11–16‐year‐old child. Specifically, the study examines: (a) the extent to which nonmarital coparents are involved in childrearing; (b) the relative levels of risk (i.e., depression, mother–coparent conflict) and protective (i.e., parenting) associated with maternal and coparent involvement; and (c) how similarly and/or differently coparent and mother variables operate with regard to youth externalizing problems. Findings reveal that a range of family members and other adults actively participate in childrearing in African American single‐mother families, coparents do not differ from mothers on certain study variables (i.e., depression and mother–coparent conflict) but do for others (parenting), and coparent involvement is associated with youth adjustment in ways that are similar to our more established understanding of maternal involvement. The potential clinical implications of the findings are discussed and future research directions are highlighted.     

Decisions from experience: How groups and individuals adapt to change

Whether groups make better judgments and decisions than individuals has been studied extensively, but most of this research has focused on static tasks. How do groups and individuals compare in settings where the decision environment changes unexpectedly and without notification? This article examines group and individual behavior in decisions from experience where the underlying probabilities change after some trials. Consistent with the previous literature, the results showed that groups performed better than the average individual while the decision task was stable. However, group performance was no longer superior after a change in the decision environment. Group performance was closer to the benchmark of Bayesian updating, which assumed perfect memory. Findings suggest that groups did not adopt decision routines that might have delayed their adaption to change in the environment. Rather, they seem to have coordinated their responses, which led them to behave as if they had better memory and subsequently delayed adaptation.     

囚徒困境博弈中对手面部表情对合作行为的影响及其作用机制

3个实验逐步深入地考察了囚徒困境博弈中, 对手的高兴、中性和愤怒面部表情对个体合作行为的影响及相关变量的中介和调节作用。实验1的结果表明, 对手的高兴表情比愤怒表情诱发了更高的合作水平, 且高兴和中性表情均比愤怒表情产生了更高的合作预期, 合作预期中介了面部表情与合作行为的关系; 实验2引入指导语操纵被试的直觉或理性决策模式, 发现实验1的结果仅出现在直觉条件下, 却未出现在理性条件下, 且整体而言直觉决策模式下比理性决策模式下更合作; 实验3采用更加严格的时间压力范式操纵被试的直觉或理性决策模式, 发现除了高兴表情比中性表情也诱发了更多的合作行为外, 其他几乎复制了实验2的结果。基于这些结果, 建立了有调节的中介模型, 以期揭示他人面部表情、合作预期、合作行为及个体决策模式之间的复杂关系。     

大脑电刺激在听觉语言加工研究中的应用

大脑电刺激是历史悠久但近年来才广泛应用在人类被试上的实验技术。通过对颅内刺激位点进行电刺激, 并分析引发的暂时性行为功能变化和记录位点的电位活动, 大脑电刺激技术可以揭示认知加工过程中脑区内的功能作用与脑区间的有效连接。通过对听觉语言加工过程相关的丘脑、听觉皮层、高级语言皮层进行电刺激, 现有研究发现了各个脑区的不同功能特点以及不同脑区间的信息传递机制, 为进一步探索听觉语言加工的神经机制提供了新的视角。     

共享经济背景下顾客公民行为和不当行为：基于社会困境理论的视角

共享经济(个体供方对个体顾客的共享模式如小猪短租平台)中顾客公民行为的促进和不当行为的治理, 成为保证共享经济可持续发展的重要议题。然而, 现有顾客行为相关研究更多是在传统经济背景下进行的探讨, 而涉及到共享经济背景下的研究难以体现共享经济的特色, 导致其未能很好地解决实践困境。上述顾客行为是在个人和集体利益发生冲突时的抉择, 即社会困境。社会困境理论可以帮助企业全面认识顾客公民行为和不当行为并有效解决困境问题。本研究拟基于社会困境理论, 探讨以下三个方面的问题: (1) 深入剖析共享经济中顾客公民行为和不当行为的概念、维度及其测量; (2) 揭示平台、供方和政府通过规则制定或社会影响策略来有效优化顾客行为的路径; (3) 阐明顾客公民和不当行为的差异性影响机制, 以及顾客社会价值导向和供方监督对顾客行为的调节作用。本研究有助于拓展现有顾客公民和不当行为的研究, 为平台、供方和政府管理提供重要参考。     

A Model of Intention to Participate in Parenting Interventions: The Role of Parent Cognitions and Behaviors

A wide range of factors, from perceived child behavior problems to sociocultural factors, have been identified as impacting the engagement of parents in parenting interventions. However, parents’ cognitions and behaviors have not been evaluated sufficiently to understand their role in initial parental engagement. The current study aimed to examine why some parents are more likely to want to participate in parenting programs and how their cognitions and behaviors are related to their intention to participate in future parenting interventions. We tested the hypothesised model of parental factors on intention to participate using structural equation modelling (SEM) in AMOS. This study (N = 6,733) analyzed existing data from the International Parenting Survey (IPS), a web-based tool developed to collect information about parents’ views on family and parenting at a population level in several countries. Results showed that parents’ coercive parenting, parental consistency, positive encouragement, relationship with their child, parental self-efficacy, psychological distress, and help-seeking behaviors were significantly related to their intention to participate in future parenting interventions. The structural model of parents’ cognitions and behaviors explained 16% of the variance in intention to participate. Although the current model explained a small but significant percentage of the variance, it expands existing understanding regarding parental cognitions and behaviors and their relationship to intention. Implications for further research and engagement practice are discussed.
