Prospective Elementary Teachers Learning to Reason Flexibly with Sums and Differences: Number Sense Development Viewed Through the Lens of Collective Activity

I present a viable learning trajectory for prospective elementary teachers’ number sense development with a focus on whole-number place value, addition, and subtraction. I document a chronology of classroom mathematical practices in a Number and Operations course. The findings provide insights into prospective elementary teachers’ number sense development. These include the role of standard algorithms and their relationship to the evolution of classroom mathematical practices that involve reasoning flexibly about number composition, sums, and differences.     

How a terror attack affects right‐wing authoritarianism,social dominance orientation,and their relationship to torture attitudes

Self‐reported level of right‐wing authoritarianism (RWA ), the two facets of social dominance orientation (SDO ‐Dominance and SDO ‐Egalitarianism) and pro‐torture attitudes were measured both in the immediate aftermath (terror salience, N = 152) of the terror attacks in Paris and Brussels and when terrorism was not salient (non‐salience, N = 140). Results showed that RWA and pro‐torture attitudes, but not SDO ‐Dominance and SDO ‐Egalitarianism, were significantly higher immediately after. Furthermore, RWA and SDO both predicted pro‐torture attitudes more strongly under terror salience. We argue that the reason why RWA is higher under terror salience is a response to external threat, and that SDO ‐Dominance may be more clearly related to acceptance of torture and other human‐rights violations, across context. Future research on the effects of terror‐related events on sociopolitical and pro‐torture attitudes should focus on person‐situation interactions and also attempt to discriminate between trait and state aspects of authoritarianism.     

The role of threat,emotions, and prejudice in promoting collective action against immigrant groups

In two studies we assessed the role of distinctiveness threat, group‐based emotions (angst, fear, and anger), and prejudice on people's willingness to engage in collective action against immigrant groups. In Study 1 (N = 222) White British participants were either informed that in the next 40 years the proportion of immigrants in the UK is unlikely to change (control condition) or that there will be more immigrants than White British people living in Britain (threat condition). We obtained support for a sequential multiple mediator model in which threat predicted British people's willingness to engage in collective action via the emotions first and then prejudice. This finding was replicated in Study 2 with an Italian sample (N = 283). These results enhance understanding of when and why advantaged groups undertake collective action against disadvantaged groups by demonstrating that distinctiveness threats and emotions promote such actions.     

服务型领导对员工建言行为的影响:领导-成员交换和学习目标取向的作用

通过对191名员工及其领导的配对问卷调查,探讨了服务型领导对员工建言行为的作用机制。结果发现:(1)服务型领导对员工建言行为有积极影响;(2)服务型领导通过领导-成员交换的中介效应影响员工建言行为;(3)员工的学习目标取向对领导-成员交换与建言行为之间的关系具有调节效应,即员工的学习目标取向越强,领导-成员交换对建言行为的影响越大;(4)学习目标取向调节了领导-成员交换对服务型领导-建言行为的中介作用。     

When death is not a problem: Regulating implicit negative affect under mortality salience

Terror management theory assumes that death arouses existential anxiety in humans which is suppressed in focal attention. Whereas most studies provide indirect evidence for negative affect under mortality salience by showing cultural worldview defenses and self‐esteem strivings, there is only little direct evidence for implicit negative affect under mortality salience. In the present study, we assume that this implicit affective reaction towards death depends on people's ability to self‐regulate negative affect as assessed by the personality dimension of action versus state orientation. Consistent with our expectations, action‐oriented participants judged artificial words to express less negative affect under mortality salience compared to control conditions whereas state‐oriented participants showed the reversed pattern.     

Perceived career congruence between adolescents and their parents as a moderator between goal orientation and career aspirations

We surveyed 601 Indonesian high school students (57.6% girls, mean age = 16.4 years) and investigated whether perceived career congruence between adolescents and their parents served as moderator between goal orientation (i.e., mastery-approach, performance-approach, and performance-avoid) and career aspirations. Hierarchical regression analyses showed that perceived congruence moderated the effects of mastery-approach and performance-approach, but not performance-avoid, on career aspirations. Mastery-approach orientation was more strongly related to career aspirations when perceived congruence was higher; whereas, performance-prove orientation was more weakly related when perceived congruence was higher. These findings highlight important roles for approach orientations and perceived career congruence between adolescents and their parents in career aspirations of adolescents in collectivist contexts.     

Atomic imaging of the interface between M23C6-type carbide and matrix in a long-term ageing polycrystalline Ni-based superalloy

Besides the well-known cube-on-cube orientation relationship (OR) between M₂₃C₆ carbide and matrix, we have determined a new OR named as the twin-related OR in a long-term ageing Ni-based superalloy on the basis of the extensive and detailed electron diffraction analyses. Furthermore, by means of atomic-resolution high angle annular dark-field imaging technique which is implemented in the aberration-corrected scanning transmission electron microscope, we elucidated the interfacial characteristics between M₂₃C₆ and matrix for above two types of ORs. Taking into account of the interfacial characteristics, we propose that the twin-related OR possesses a higher total interfacial energy. Thus, its frequency of occurrence is lower than that of the cube-on-cube OR though both ORs are usually seen in the long-term ageing samples.     

Iranian Psychotherapists’ Behaviors and Beliefs Toward Sexual Orientation and Gender Identity

The aim of this study is to investigate Iranian psychotherapists’ behaviors and beliefs toward sexual orientation and gender identity. The sample consisted of 358 Iranian psychotherapists, of whom 29.3% (n = 105) were male and 67% (n = 24) were female. Results from the chi-square analyses showed that more male participants reported accepting homosexual clients and treating them as having a pathological disorder than their female counterparts; and licensed respondents reported engaging more in accepting only male or female clients, accepting more homosexual and transgender clients for treatment, and treating them as having a pathological disorder when compared with their unlicensed counterparts. Furthermore supervised respondents reported accepting more homosexual clients than their unsupervised counterparts. However results from the multivariate analysis of variance has indicated that the female participants reported “accepting homosexuals or transgender clients for treatment” more often than the male participants; unsupervised participants reported “accepting homosexual or transgender clients for treatment” and “treating homosexuality per se as a pathological disorder” more often than their supervised counterparts.     

Making Sense in and of the Asexual Community: Navigating Relationships and Identities in a Context of Resistance

Despite some increased visibility in recent years, the asexual community and asexuality generally remain largely unknown. Aiming to demystify asexuality, this paper discusses the context of anti‐asexual animosity in which the (largely American) asexual community is situated. Specifically, the asexual community constructed itself in response to hostility, including explicit anti‐asexual discrimination, homophobia against asexual people perceived to be lesbian or gay, and the negative impact of (implicit) pathologising low sexual desire. This theoretical paper outlines some of the unique challenges asexual people face negotiating identities and relationships; the collective sense‐making strategies they use (generating language and discourse) to do so; and why these things are central to understanding asexual people's experiences. This is accomplished through a purposeful review of literature and a case study of the Asexual Visibility and Education Network as an asexual community space. Understanding the challenges asexual people face and the resources they invoke to overcome them helps applied psychologists develop the cultural competence they need to work effectively with the asexual people they will encounter.
