Kinetic study of static recrystallization in an Fe–Al–O ultra-fine-grained nanocomposite

A nearly abrupt coarsening of grains is observed in a newly developed Fe–Al–O ultra-fine-grained nanocomposite with a significant volume fraction (4%) of alumina nano-precipitates. The microstructure of the alloy was analysed in different states (as-received and annealed) by means of scanning electron microscopy, transmission electron microscopy (TEM) and hardness. The initial grain size 150–200 nm increases up to 50 μm during annealing 1000 °C/8 h and thereafter demonstrates saturation. A linear correlation between volume fraction of coarse grains and hardness was found. It was identified by TEM that alumina nano-precipitates stabilize the dislocation microstructure against recovery very effectively and the grain coarsening is due to fast growth of very few dislocation free grains. Thus, the observed grain coarsening has the attributes of static recrystallization.     

员工跨界行为的作用机制：网络中心性和集体主义的作用

员工跨界行为正在成为团队领域的热点课题, 但目前为止尚缺乏在中国情境下关于员工跨界行为作用机制的系统研究。本研究通过对来自61个团队的领导及其292名员工的两波纵向数据进行跨层分析, 将文化和社会网络理论整合入跨界行为领域, 在控制了个体层次的员工年龄、教育程度、性别、本团队工作时间和个人的集体主义导向, 以及团队层次的团队规模后, 发现员工跨界行为有助于提升其团队内部网络中心性的地位, 并进而促进其任务绩效, 团队集体主义氛围在员工跨界行为和网络中心性的关系中到显著的调节作用。     

工作家庭两不误为何这么难？基于工作家庭边界理论的探讨

为探讨工作家庭冲突对员工工作态度和行为倾向的影响, 以国内某大型制造企业集团位于北京、杭州、西安等地7家分公司的545名员工为样本, 采取问卷调查法在两个不同时段获取数据, 考察了角色压力(角色冲突、角色模糊和角色超载)在工作干涉家庭和家庭干涉工作这两种对偶冲突模式与员工工作满意度和离职意向之间的中介作用机制。结果显示：角色压力在工作家庭冲突与工作满意度和离职意向之间起到完全中介作用, 工作满意度在角色压力和离职意向之间起到部分中介作用。结论有助于分析工作家庭冲突的深层原因并采取恰当的干预策略, 降低工作家庭冲突对员工工作态度和行为倾向的负面影响。     

A survivor's account of sexual exploitation by a Jungian analyst

This essay explains the ramifications of sexual exploitation in the context of Jungian analysis. It argues that misuse of work specifically framed as Jungian can cause severe, deep, and long-lasting harm. It suggests that Jungian professionals strengthen and increase the scope of their actions to deter rogue colleagues from exploiting their analysands.     

Tailoring the crack-tip microstructure: a novel approach

This investigation demonstrates a way to innovatively modify the ferritic microstructure at a local scale, particularly at the failure prone area such as Charpy V-notch (CVN) root. Tensile pre-strain (PS) up to 6% and 12% were employed before annealing (An) the samples at 650°C for 15?minutes. Ferrite grain size increased sharply and gradually (along the distance ahead of the notch root) within the microstructurally modified region in 6–12% pre-strained and annealed samples, respectively. The critical strain which promotes strain-induced boundary migration (SIBM), was found to be 0.1 which resulted in abnormally coarse ferrite grains.     

Specifying the boundary conditions of the multimedia effect: The influence of content and its distribution between text and pictures

It was investigated whether the beneficial effect of picture presentation might be influenced by the content conveyed through text and pictures and the way information is distributed between them. Ninety‐nine students learnt in five between‐subjects learning conditions (i.e., text with spatial contents plus pictures, text with visual contents plus pictures, only text with spatial contents, only text with visual contents, only picture) about a tourist centre and a holiday farm. Results showed that pictures (i.e., maps) were beneficial for learning if spatial knowledge had to be acquired, but did not support learning when non‐spatial, visual knowledge had to be acquired. Furthermore, a high overlap of spatial information in text and picture was helpful, which can be explained by the assumption that learning is a text‐guided process. On the other hand, regarding non‐spatial visual information, a high text‐picture overlap did not influence learning, probably because text alone was sufficient for acquiring visual knowledge. The implications of these findings are discussed.     

Students' Ethical Decision‐Making When Considering Boundary Crossings With Counselor Educators

Counselor education students (N = 224) rated 16 boundary‐crossing scenarios involving counselor educators. They viewed boundary crossings as unethical and were aware of power differentials between the 2 groups. Next, they rated the scenarios again, after reviewing 1 of 4 ethical informational resources: relevant standards in the ACA Code of Ethics (American Counseling Association, 2014), 2 different boundary‐crossing decision‐making models, and a placebo. Although participants rated all resources except the placebo as moderately helpful, these resources had little to no influence on their ethical decision‐making. Only 47% of students in the 2 ethical decision‐making model groups reported they would use the model they were exposed to in the future when contemplating boundary crossings     

Two field studies on the effects of alcohol on eyewitness identification,confidence, and decision times

In two field studies, bar tenants (Ns = 86 and 190, respectively) were successively approached by confederates C1 and C2 on a night out. Confederate C3 then presented participants with a six‐person target‐absent or target‐present lineup concerning C1 or C2 (immediate test). Several days later, participants viewed a lineup regarding the confederate they had not attempted to identify earlier (C1/C2; delayed test). An immediate compared with a delayed, sober identification test did not increase the risk of a false identification decision. A blood alcohol concentration of 0.06–0.07% best discriminated accurate from inaccurate decisions. Choosers with a blood alcohol concentration ≤ 0.06% showed excellent calibration and little overconfidence, and their confidence was a strong indicator of accuracy (i.e., good resolution). Choosers with a higher intoxication level displayed poor calibration and strong overconfidence. Nonchoosers were generally poorly calibrated. Combined analyses showed a negative effect of intoxication on one's ability to discriminate the target from nontargets.     

Shifting shadows: shaping dynamics in the cultural unconscious

Jung has suggested that wars, social upheavals and religions are 'but the superficial symptoms of a secret psychic attitude unknown even to the individual himself, and transmitted by no historian ...' (Jung 1964, para. 315; emphasis author's). With a focus on South Africa and some dream material, I explore this idea with particular emphasis on the cultural unconscious and the emerging theory of cultural complexes. Different cultures demand the repression of different aspects of the self and have different ways of actualizing a moral code. These repressions are part of what make up a dynamic and shifting cultural complex which inevitably plays a part in historical change. In turn, historical change plays its part in shifting these dynamics. In the analytic setting via the transference and countertransference, we are familiar with what is being repressed in relation to shadow dynamics, complexes and obsolete defences. Such dynamics relate to themes of boundary, identity and otherness which, in turn, reach back to early infantile strivings as well as forward in the service of unfolding. Central to this dynamic is the absorption of cultural attitudes--including that which must be repressed, allowed in or defended against. Major political shifts--historical change--inevitably affect cultural dynamics, 'secret psychic attitude(s)' and shifting shadows.
