Vacancy-mediated structural changes in Au–Cu nanoparticles

We report the formation of new phases in bimetallic Au–Cu nanoparticles. These phases were observed in nanoparticle synthesised by adopting a three-step protocol in a single pot. Nanoparticles at 180°C for 1?h led to the formation of single-phase solid solution of Cu in Au. Subsequent heat treatment at 290°C for 2?h of these Au–Cu nanoparticles revealed three new phases. One of them relates to the modification of occupancy of Cu in an ordered AuCu tetragonal phase (tP4). This cell although retains tetragonal symmetry but displays metrical properties akin to that of a cube. The other two relates to vacancy ordering along <111> directions in the {111} planes of an ordered AuCu3 cubic phase (cP4). On the one hand, statistical occupancy of vacancy on Cu site in this cell leads to the reduction of cell size from ～3.75?Å to ～3.5?Å whereas ordering of vacant layer on the other hand gives rise to symmetry breaking. Former continues to display cubic symmetry whereas latter transforms to a trigonal cell.     

Monothematic delusion: A case of innocence from experience

Empiricists about monothematic delusion formation agree that anomalous experience is a factor in the formation of these attitudes, but disagree markedly on which further factors (if any) need to be specified. I argue that epistemic innocence may be a unifying feature of monothematic delusions, insofar as a judgment of epistemic innocence to this class of attitudes is one that opposing empiricist accounts can make. The notion of epistemic innocence allows us to tell a richer story when investigating the epistemic status of monothematic delusions, one which resists the trade-off view of pragmatic benefits and epistemic costs. Though monothematic delusions are often characterized by appeal to their epistemic costs, they can play a positive epistemic role, and this is a surprising conclusion on which, so I argue, all empiricists can agree. Thus, I show that all empiricists have the notion of epistemic innocence at their disposal.     

Power and provocativeness: The effects of subtle changes in clothing on perceptions of working women

The current study investigates the effects of subtle changes in professional women’s dress on women’s perceptions of power and competence. We replicate and extend Howlett, Pine, Cahill, Orakcioglu, and Fletcher’s (2015) research showing that women in provocative clothing are rated as less competent. We used a larger sample, tested a second independent variable, and fine-tuned the design for higher face validity. Participants (N = 198, 170 women and 29 men) from a Midwestern university in the USA rated four photographs of professionally dressed women whose blouses varied in the number of buttons left undone and whether they wore a camisole. We found main effects of buttons (undone/done) and camisoles (on/off) for participants perceptions of intelligence, competence, powerfulness, and on a global rating score. Results also showed significant interaction effects between buttons and camisoles on ratings of powerfulness. The results have many implications for how women dress professionally.     

Demandingness and Boundaries Between Persons

ABSTRACT

Demandingness objections to consequentialism often claim that consequentialism underestimates the moral significance of the stranger/special other distinction, mistakenly extending to strangers demands it is proper for special others to make on us, and concluding that strangers may properly demand anything of us if it increases aggregate goodness. This argument relies on false assumptions about our relations with special others. Boundaries between ourselves and special others are both a common and a good-making feature of our relations with them. Hence, demandingness objections that rely on the argument in question fail. But the same observations about our relations with special others show that there are many demands special others may not properly make, and since we cannot be more guilty of unjustified partiality in insisting on boundaries between ourselves and strangers than on boundaries between ourselves and special others, there are – as demandingness objections maintain – some demands strangers may not properly make on us.     

Cell phone usage relational regulation strategies of older South Africans

This study explored older South Africans’ relational regulation strategies in using their cell phones to address their social goals and psychosocial needs. Nineteen older South Africans (17 female; 2 male), aged 60 and older, who had access to a cell phone and represented different socio-economic levels based on the Living Standard Measurement (LSM) scale, participated in the Mmogo-method®, a visual data-collection method. Thematic and visual analysis revealed that the subjective assessment of cell phone users’ competence determined the type of relational regulation strategy they apply. Findings revealed older persons to adopt three relational regulation strategies in their cell phone use: (i) postponement of need satisfaction; (ii) asking directly; or (iii) negotiating for needs satisfaction. The findings might facilitate programmes that promote cell phone use in older persons to address their social needs and promote healthy intergenerational interactions.     

Do Japanese Youth Proactively Form Identities? An Investigation of Independent Self Formation

This article addresses the debate concerning cultural differences in independent and interdependent self formation among Japanese youth. Independent self formation is defined as any purposive action to form a self actively through individual efforts. This study provides evidence that the majority of Japanese youth, despite their culturally collectivist backgrounds, form selves individually at the level of specific activities. High levels of active self formation were found among 41% of the sample. These findings contribute to the literature on both self development and identity formation, with the finding that both independent self formation and proactive identity formation occur among a significant proportion of Japanese students.     

同性恋者的内化同性恋嫌恶：形成及影响机制

内化同性恋嫌恶是同性恋者经历对外界偏见的内化过程后,所形成的对自身性取向的负性态度。本文在回顾和分析内化同性恋嫌恶形成及影响机制相关研究的基础上,尝试提出整合性的内化同性恋嫌恶形成/影响机制假设模型。最后,本文提出进一步验证和发展内化同性恋嫌恶形成/影响机制模型、考察缓解内化同性恋嫌恶影响的保护因素及加强内化同性恋嫌恶的本土化研究是未来的研究方向。     

Evaluation of a statewide initiative to reduce expulsion of young children

This program evaluation study describes 3 years of implementation of Arkansas's BehaviorHelp (BH) system, a statewide expulsion prevention support system for early care and education (ECE). BH coordinates three tiers of supports to ECE professionals, including phone support, on‐site technical assistance (TA), and infant and early childhood mental health consultation (IECMHC). We examine differences in characteristics of those served across BH service tiers, describe short‐term case outcomes, and explore factors associated with expulsions. BH accepted referrals for 1,195 children in 488 ECE programs. The majority of referrals involved male children over the age of three, and most cases were assigned to the TA tier (68.5%). Cases assigned to receive IECMHC (28.4%) were more likely to involve children in foster care, receiving developmental therapies, and with higher rates of exposure to potentially traumatic events. The expulsion rate among referred children was 2.9%, and reported teacher engagement with the support process was high. Teachers receiving IECMHC services reported significant improvements in children's symptoms of emotional and behavioral problems. Exploratory analyses revealed that risk factors for expulsion included being a male, in foster care, in a lower quality ECE environment, and having a teacher with less training in social–emotional development.     

Willingness to fake: Examining the impact of competitive climate and hiring situations

Applicants may be willing to fake in job interviews with the aim of creating a positive impression. In two vignette‐based experiments, we examined if a competitive—versus noncompetitive—climate (Study 1) and hiring situation (Study 2) increased participants' willingness to fake. We also examined if Honesty–Humility and Competitive Worldviews moderated the relation between willingness to fake and how competitive participants believed they must be in order to secure the job. Results demonstrated that a competitive climate and hiring situation increased willingness to fake. Honesty–Humility and Competitive Worldviews were related to willingness to fake, but these relations did not change substantially at different levels of perceived need for competitiveness. Overall, results lend some theoretical support to propositions about applicant faking.
