Online low‐key conspicuous behavior of fashion luxury goods: The antecedents and its impact on consumer happiness

Nowadays, people tend to show off in a more conservative rather than ostentatious way, that is, “low‐key style.” This paper focuses on consumers' low‐key conspicuous behavior on social media after they purchase fashion luxury goods, so as to explore the antecedents of this behavior, as well as its impact, on consumer happiness. Our results show that motivations for self‐representation and avoidance of negative comments from others trigger the low‐key conspicuous behavior. Afterward, this behavior will positively affect consumers' short‐term happiness through both perceived self‐image and perceived interpersonal relationship, while enhancing long‐term happiness only through perceived interpersonal relationship. The reason may be that the temporary pleasure brought by the improvement of perceived self‐image is not enough to raise the quality of life, but an improvement in one's interpersonal relationship is a lifelong benefit.     

生涯规划清晰度对大学生学习参与的影响:有调节的中介模型

考察生涯规划清晰度对大学生学习参与的影响机制。采用生涯规划量表、学习过程问卷、团队学习氛围量表和学习参与量表对728名大学生进行调查。结果发现:(1)生涯规划清晰度对学习参与具有显著正向影响;(2)学习动机在生涯规划清晰度与大学生学习参与间起部分中介作用;(3)同伴学习氛围在中介模型的后半段路径中起调节作用。这一结论有助于理解生涯规划清晰度对学习参与的作用机制,对提升大学生学习参与水平具有一定的启发意义。     

Microwave-induced heating of a single glassy phase and a two-phase material consisting of a metallic glass and Fe powder

Metallic glasses exhibit low viscosity in a temperature range between the glass transition and the crystallization temperature, a feature that allows successful sintering of glassy powders. Microwave heating, being volumetric, has significant advantages over conventional heating in materials processing, such as substantial energy savings, high heating rates and process cleanliness. In the present study, we investigate the stability of Cu₅₀Zr₄₅Al₅ glassy powders and the formation of a bulk two-component metallic glassy-crystal sample by microwave heating in a single-mode cavity (915 MHz) in an alternating magnetic field.     

人格测量：从累积式模型到展开式模型

当前大多数人格测量都采用的是累积式反应模型方法,该模型假设被试在测验上的得分随其能力或特质提高而增加,但是随着人格测量技术的不断发展,这一模型的实施效果遭到了质疑,研究者们开始关注展开式模型,该模型认为被试的反应取决于被试能力和项目阈值的匹配程度,当被试能力与项目阈值完全匹配时,被试做出肯定回答的概率达到最高点,称之为“理想点”,展开式模型的目的就是找到被试的理想点,从而寻找其真正的态度强度或人格特质水平。GGUM作为一种比较成熟的展开式模型,已经开始应用于人格测量的各个领域,但仍需要进行大规模的试测,在评估和预测效度方面积累经验,建立业界认可的心理测量学标准,不断探讨和开发相应的心理测量理论和简便易行的统计程序。     

Developmental trajectories of aggression from late childhood through adolescence: similarities and differences across gender

Although numerous investigations of overt aggressive and antisocial trajectories have been undertaken, there is a dearth of literature examining gender differences and similarities in trajectory patterns and their correlates. To address these gaps, we investigated gender differences in the prevalence rates, predictive validity during transition to adulthood, childhood risk factors, and adolescent correlates of different trajectories of teacher-reported overt aggression (i.e., fights, argues, gets in trouble) among 220 participants (116 girls and 104 boys) evaluated annually from grade 4 to grade 12. Four patterns of trajectories were identified: low, increasing (i.e., adolescent-onset), decreasing (i.e., childhood-limited), and high (i.e., childhood-onset). A large proportion of youth, particularly girls, displayed low levels of aggression over time. A small proportion followed the childhood-onset trajectory. Across gender, the childhood-onset trajectory was associated with the highest rates of maladjustment during the transition to adulthood, the highest number of childhood risk factors, and multiple problems during adolescence. The adolescent-onset trajectory was associated with few childhood risk factors, but with high levels of independent status during adolescence. In contrast, the childhood-limited trajectory was associated with several childhood risk factors, but high levels of parental monitoring and school engagement during adolescence. Romantic involvement differentiated the adolescent-onset and childhood-limited trajectories among girls.     

情绪和框架效应对个体捐赠决策影响的实验研究

本研究采用双因素被试间实验具体考察了特定即时情绪和框架效应对于捐赠决策的影响,结果发现存在显著的主效应和交互作用。悲伤情绪能够增加捐赠者的捐赠意愿,快乐情绪会降低捐赠者的捐赠意愿;损失框架能够增加捐赠者的捐赠意愿,幸存框架会降低捐赠者的捐赠意愿;快乐情绪的捐赠者的捐赠决策受框架效应的影响要弱于中性情绪和悲伤情绪的捐赠者,捐赠者在幸存框架下的捐赠决策受情绪的影响比在损失框架下受情绪的影响更小。     

生物反馈疗法对大学生考试焦虑的治疗作用

探讨生物反馈疗法对大学生考试焦虑的治疗作用。在某大学随机抽取学生1500名,采用考试焦虑量表进行筛查,选取焦虑组和对照组各30名。利用生物反馈疗法进行干预,采用脑电α波相对功率、肌电和皮电导联进行检测,每周2次,持续4周。结果表明：1.经过4周的干预,焦虑组干预前后各生理指标存在差异;2.生物反馈疗法干预考试焦虑在疗效上存在性别差异。结论：生物反馈疗法能有效降低大学生考试焦虑水平,对其治疗取得良好的效果。     

心理健康素质测评系统·中国成年人一般自我概念量表的编制

旨在编制适合中国成年人的一般自我概念测量工具。通过理论分析,建构了一般自我概念的四个维度,包括积极性、清晰性、悦纳性和调节性,并据此编制了中国成年人一般自我概念量表。分别选取北京地区450名和400名大学生进行预试和正式测试：验证性因素分析表明,建构的一般自我概念四维测量模型结构合理,拟合良好;项目及信效度分析表明,量表各项目区分度良好,信、效度符合心理测量学要求。因此,该量表可作为成年人一般自我概念和自我心理健康素质的测量工具。     

网络游戏成瘾者的内隐攻击性研究

本研究通过IAT对网络游戏成瘾者的内隐攻击性进行了研究。研究表明:(1)与非网络游戏成瘾者相比,网络游戏成瘾者持有自我攻击性信念和对攻击性的更为积极的内隐态度;(2)网络游戏成瘾者与非网络游戏成瘾者在外显攻击性上没有表现出显著差异。     

对从HSK题库中计算机自动生成试卷稳定性的试验检验

由计算机从题库中自动生成的试卷能否保持难度的相对稳定？根据IRT进行的等值误差范围有多大？为了回答这些问题,本文以共同组等值作为标准,对基于IRT之上的共同题等值误差进行了试验检验。试验中,采取一定措施保证了考生的动机水平。结果显示,IRT等值的校正方向都是正确的。在4个分测验中有3个分测验的的等值校正效果较理想,1个分测验的等值校正效果不够理想。计算机自动生成的试卷与原有人工命制的试卷在得分方面比较一致,分数相关达到0.931,获得证书的情况也是比较一致的。
