鲍德里亚对马克思拜物教理论的误识及其方法论根源

鲍德里亚通过对马克思拜物教概念、政治经济学批判模式等理论分析后认为,马克思的拜物教理论仅仅是一种心理学意义上揭示的人对实体物的迷恋,其政治经济学批判模式不仅无法实现对拜物教的颠覆,最终还会陷入到资本逻辑的普遍化之中。事实上,鲍德里亚这一理论是对马克思拜物教理论的严重误识,其根源在于非历史性的社会学方法。这一方法不仅使他脱离了历史唯物主义基本框架,还导致了在消解拜物教问题上走向了不可能的绝望之路。     

程度函数及其可靠性

通过实验及理论分析,验证并给出了：１．程度函数ａ的可靠性θ的取值范围为：１／ｍ≤θ≤１／ｍ∑ｂｋｙｊｐ。θ值的大小与可靠性呈反向变化：ａ的可靠性大,θ值小,ａ的可靠性小θ值大,一般情况下的θ值,为θ的上界与下界之和的一半;２．采用集值统计模型和一般统计模型处理多级估量法多人次结果,所得到的程度函数平均数几乎相等,而且相关系数高达０．９７７．非常显著．分组数据计算、单一数据计算或全部数据统一计算的程度函数ａ及可靠性θ值也都相等．３．一般统计模型处理多级估量法多人次结果所得到的标准差σ,只反映各被试的程度函数之间的变异,与程度函数可靠性无关（相关系数０．００２４,非常不显著）．如果个人结果中按公式θ＝１／ｍ∑ｅｊ再计算可靠性θ值,然后再求其平均数及标准差,还可进一步了解可靠性θ值的变异情况．     

Convergent Thinking Moderates the Relationship between Divergent Thinking and Scientific Creativity

Creativity plays an important role in human society as well as in individual development, and creativity in the domain of science is a specific form. A body of research had demonstrated the role of divergent thinking in creativity. The role of convergent thinking had also been recognized, but more empirical evidence was needed. To investigate the interaction between convergent and divergent thinking on adolescent scientific creativity, the current study tested 588 high school students. The results showed that convergent thinking interacted with fluency/flexibility of divergent thinking on scientific creativity. In particular, divergent thinking predicted creativity in those high in convergent thinking. Findings suggested a threshold-setting effect of convergent thinking, which meant only when convergent thinking capacity reached a certain level, divergent thinking could play a role in scientific creativity. Implications for future research and educational practice were discussed.     

“I Am My Own Gender”: Resilience Strategies of Trans Youth

Nineteen trans youth participated in a phenomenological study of their resilience strategies for navigating stressors in their lives. The authors identified 5 supports and 6 threats to participants’ resilience. The 5 themes of resilience were: (a) ability to self‐define and theorize one's gender, (b) proactive agency and access to supportive educational systems, (c) connection to a trans‐affirming community, (d) reframing of mental health challenges, and (e) navigation of relationships with family and friends. The 6 major threats to participants’ resilience were: (a) experiences of adultism, (b) health care access challenges, (c) emotional and social isolation, (d) employment discrimination, (e) limited access to financial resources, and (f) gender policing.

Temporal Discounting Mechanisms of Future‐oriented Coping: Evidence from Delay Discounting and Task Prioritization Paradigms

Four studies were conducted to examine the relationship between future‐oriented coping and temporal discounting under different situational conditions. In Study 1, 138 participants were primed with either stressful or neutral stimuli, followed by a delay‐discounting task. In Study 2, 118 participants were primed with either stressful or neutral stimuli, followed by a task‐prioritization activity. The results of both studies indicated that future‐oriented coping had a significant negative association with temporal discounting or the number of rational choices in the neutral‐priming condition, but the relationship was not significant in the stress‐priming condition. In Study 3, qualitative data revealed that the major reason for shifting choices from larger but later payoffs to smaller but sooner rewards in a stressful condition was to reduce the stressful mood, create a positive mood, and promote a sense of accomplishment. This explanation was corroborated by Study 4, in which one group was allowed to choose an immediate payoff and the other group was blocked from choosing that immediate payoff. We confirmed that post‐test anxiety was significantly lower in the immediate payoff group compared with the delayed‐payoff group in proactive and preventive coping, using pre‐test anxiety as a covariate. Preventive coping helped to reduce anxiety levels in a stressful condition only when there was a choice to obtain an immediate payoff. These findings underscore the relationship between future‐oriented coping and temporal discounting, as well as the flexibility of discounting in the face of stress.

Exposure to nature counteracts aggression after depletion

Acts of self‐control are more likely to fail after previous exertion of self‐control, known as the ego depletion effect. Research has shown that depleted participants behave more aggressively than non‐depleted participants, especially after being provoked. Although exposure to nature (e.g., a walk in the park) has been predicted to replenish resources common to executive functioning and self‐control, the extent to which exposure to nature may counteract the depletion effect on aggression has yet to be determined. The present study investigated the effects of exposure to nature on aggression following depletion. Aggression was measured by the intensity of noise blasts participants delivered to an ostensible opponent in a competition reaction‐time task. As predicted, an interaction occurred between depletion and environmental manipulations for provoked aggression. Specifically, depleted participants behaved more aggressively in response to provocation than non‐depleted participants in the urban condition. However, provoked aggression did not differ between depleted and non‐depleted participants in the natural condition. Moreover, within the depletion condition, participants in the natural condition had lower levels of provoked aggression than participants in the urban condition. This study suggests that a brief period of nature exposure may restore self‐control and help depleted people regain control over aggressive urges.

     

Microstructure and martensitic transformation behaviors of a Ti–Ni–Hf–Cu high-temperature shape memory alloy ribbon

The Ti₃₆Ni₄₁Hf₁₅Cu₈ melt-spun ribbon undergoes a B2 ? B19′ transformation upon cooling and heating. When the Ti₃₆Ni₄₁Hf₁₅Cu₈ melt-spun ribbon is annealed at 873 K for 1 h, the spherical (Ti, Hf)₂Ni particles with a diameter of 20–40 nm precipitate in the grain interior. The fine (Ti, Hf)₂Ni precipitates improve the stability of phase transformation temperatures and cause martensite domains, with (001) compound twins in three orientations dominant instead of (011) type I twins. {111}-, {113}- and (001)//{111}-type boundaries are observed among these martensite domains. When the (Ti,Hf)₂Ni precipitates coarsen, (011) type I twins become main martensite structures in the ribbon annealed at 973 K for 1 h.     

A novel lattice correspondence of B19 → B19′ transformation in Ti–Ni–Cu shape memory alloy thin film

In this study, we found a novel lattice correspondence of the B19–B19′ transformation in a Ti–Ni–Cu thin film: (1?1?1)_B19′//(0?0?1)_B19, [0, 1, 1]_B19′//[1?0?0]_B19. Near the coarse precipitate and the grain boundaries, the B19′ martensite forms with the novel lattice correspondence to product the (1?1?1) type I twinning instead of the usual (0?0?1) compound twinning. Crystallographic analyses show that the novel lattice correspondence results from the local stress concentration.
