Effect of deep cryogenic treatment on carbon segregation in Cr8Mo2SiV tool steel during tempering

Carbon segregation in Cr8Mo2SiV tool steel after common heat treatment (CHT) and deep cryogenic treatment (DCT) has been investigated by X-ray diffraction (XRD), transmission electron microscopy (TEM) extraction replica and three-dimensional atom probe (3DAP) tests. The XRD results show that most of the retained austenite transformed to martensite after DCT. The TEM results confirm the transformation of blocky retained austenite to twin martensite during DCT. The 3DAP results reveal the segregation of carbon atoms and the maximum carbon fraction in carbon-rich regions increases after DCT. The peak carbon concentration in carbon-rich regions of SDC99 steel after CHT and DCT are 8 at. % and 15 at. %, respectively. The segregated carbon atoms grew into nuclei for nanoscale carbides precipitation on subsequent tempering.     

Be loyal but not addicted: Effect of online game social migration on game loyalty and addiction

To increase game loyalty but decrease game addiction, this study examines online game social migration and tests the mediating effects of offline social value and maladaptive cognition on the basis of the theory of consumption value and the cognitive behavioral model of pathological Internet use. The results are as follows: (i) Overall, online game social migration is associated with greater game loyalty and less game addiction; (ii) The positive association between online game social migration and game loyalty was mediated by offline social value; and (iii) Online game social migration is associated with lower game addiction. This paper provides a new perspective (taking into account both business interests and players' psychological health) for online game research and also offers practical guidance for cooperation between game companies and the public.

幼师生职业决策自我效能、学校适应与职业犹豫不决之间的关系

运用自编的职业决策自我效能量表,考察334名幼师生职业决策自我效能、学校适应与其职业犹豫不决的相关关系,结果发现职业决策自我效能对学校适应预测职业犹豫不决起到部分中介作用。进一步研究发现幼师生职业决策自我效能中的目标设定、自我概念和自我评价对其学校适应预测职业犹豫不决起部分中介作用,职业信息收集和学业成绩对此的中介效应不显著。     

老年人生命态度及其与抑郁和社会支持的关系

使用死亡态度描绘量表(修订版)、流调中心用抑郁量表和个人资源量表2000对京津地区的516位老年人进行问卷调查,探讨老年人生命态度的结构及特点,并选取几个因素探讨其对老年人生命态度的影响。结果表明:(1)生命态度的结构包含死亡恐惧、死亡逃避、自然接受、趋近接受和逃离接受五个维度。(2)在生命态度的五个维度中,自然接受和趋近接受存在显著的性别差异,死亡恐惧、自然接受和逃离接受存在显著的教育程度差异;(3)抑郁与自然接受呈显著负相关,与生命态度其他四个维度呈显著正相关;社会支持与死亡恐惧呈显著负相关,与自然接受呈显著正相关。

Expectations and beyond: The nexus of AI instrumentality and brand credibility in voice assistant retention using extended expectation-confirmation model

AI-based voice assistants (AIVA) are capable of interpreting human speech and responding with useful information, aiding with tasks, and controlling other devices. The usage of these AIVAs has grown significantly worldwide. Despite this growth, studies on user behavior related to continued usage intention of AIVAs and effects on the long-term commercial sustainability of brands, remain low. What is less understood is the potential of AI instrumentality attributes and brand credibility components in provoking shifts in post-use behavior of AIVAs. This study proposes a model which expands on the Expectation-Confirmation Model for user continuance behavior of AIVAs, by integrating user's technology related traits, AI instrumentality attributes and brand credibility. To verify the research hypotheses, the study employed partial least square—structural equation modelling, based on 281 validated responses of a survey. This study highlights the significance of Optimism, Innovativeness, and Discomfort for post-adoption confirmation. Higher post-adoption confirmation is strongly associated with perceived intelligence, anthropomorphism, information quality, and system quality. Anthropomorphism and information quality are key factors for brand expertise, while anthropomorphism and system quality are significant for brand trustworthiness. The study confirms that brand expertise and trustworthiness lead to post-use satisfaction and use continuance intention. Understanding the antecedents of satisfaction and continuance intention extends the existing literature on AIVAs and provides valuable insights for academics and practitioners alike. Some implications for researchers and managers are discussed.

意外地点任务中不同测试问题及意图理解与执行功能的关系

旨在讨论意外地点任务中“知否问题”与“预测问题”可能存在的差异及两者与执行功能任务的关系,并初步探讨意图理解与执行功能间的关系。用意外地点任务、膝跳反射任务和两个执行功能的任务（DCCS和手部游戏）对59名3~5岁的儿童施测。结果显示：（1）儿童在意外地点任务的“知否问题”上的表现显著好于“预测问题”,儿童对“知否问题”和“预测问题”的回答可能反映了心理理论发展的不同阶段。（2）膝跳反射任务,DCCS任务与“知否问题”三者间有显著的相关,且其高相关在排除年龄及语言能力的影响后仍保持显著。“双表征区分结构”可能是三者间具有共同的成分。
