Effects of intergroup exclusion on individual needs threat and behavior tendencies

This study explores the effects of intergroup exclusion on need‐threat and the behavioral tendencies of excluded individuals. Results show that those excluded by in‐group members perceived more threat to relational needs, while participants excluded by out‐group members perceived more threat to efficacy needs. In addition, participants excluded by out‐group members displayed significantly more aggression intention and less helping intention than those who were excluded by in‐group members. This study indicates that the group relationship between excluders and the excluded will directly affect threat perception and behavioral responses.     

Photography and Social Media Use in Community‐Based Participatory Research with Youth: Ethical Considerations

Community‐based participatory researchers increasingly incorporate photography and social media into their work. Despite its relative infancy, social media has created a powerful network that allows individuals to convey messages quickly to a widespread audience. In addition to its potential benefits, the use of social media in research also carries risk, given the fast pace of exchanges, sharing of personal images and ideas in high accessibility, low privacy contexts and continually shifting options and upgrades. This article contributes to the literature examining ethical considerations for photography and social media use in community‐based participatory research. We describe three key ethical dilemmas that we encountered during our participatory photography project with Latina/o youth: (a) use and content of images and risk; (b) incentives and coercion; and (c) social media activity and confidentiality. We provide our responses to these challenges, contextualized in theory and practice, and share lessons learned. We raise the question of how to contend with cultural shifts in boundaries and privacy. We propose that evaluating participant vulnerability versus potential empowerment may be more fitting than the standard approach of assessing risks and benefits. Finally, we recommend upholding the principles of participatory research by co‐producing ethical practices with one's participants.     

The effect of positive affect on conflict resolution: Modulated by approach-motivational intensity

The motivational dimensional model of affect proposes that the influence of positive affect on cognitive processing is modulated by approach-motivational intensity. The present research extended this model by examining the influence of positive affect varying in approach-motivational intensity on conflict resolution—the ability to resolve interference from task-irrelevant distractors in order to focus on the target. The global–local task (Experiment 1) and letter-Flanker task (Experiment 2) were used to measure conflict resolution. Additionally, the 4:2 mapping design that assigns two kinds of task-relevant stimuli to one response key and two more to another response key was used in these two tasks to dissociate stimulus and response conflict. Results showed that positive affect varying in approach motivation had opposite influences on conflict resolution. The opposite influences are primarily reflected in low approach-motivated positive affect impairing, while high approach-motivated positive affect facilitating the resolution of response conflict. Conversely, the stimulus conflict was slightly influenced. These findings highlight the utility of distinguishing stimulus and response conflict in future research.     

Person‐specific versus multilevel autoregressive models: Accuracy in parameter estimates at the population and individual levels

This paper compares the multilevel modelling (MLM) approach and the person‐specific (PS) modelling approach in examining autoregressive (AR) relations with intensive longitudinal data. Two simulation studies are conducted to examine the influences of sample heterogeneity, time series length, sample size, and distribution of individual level AR coefficients on the accuracy of AR estimates, both at the population level and at the individual level. It is found that MLM generally outperforms the PS approach under two conditions: when the sample has a homogeneous AR pattern, namely, when all individuals in the sample are characterized by AR processes with the same order; and when the sample has heterogeneous AR patterns, but a multilevel model with a sufficiently high order (i.e., an order equal to or higher than the maximum order of individual AR patterns in the sample) is fitted and successfully converges. If a lower‐order multilevel model is chosen for heterogeneous samples, the higher‐order lagged effects are misrepresented, resulting in bias at the population level and larger prediction errors at the individual level. In these cases, the PS approach is preferable, given sufficient measurement occasions (T ≥ 50). In addition, sample size and distribution of individual level AR coefficients do not have a large impact on the results. Implications of these findings on model selection and research design are discussed.     

Of Tooth and Claw: Predator Self-Identifications Mediate Gender Differences in Interpersonal Arrogance

Men often score higher than women do on traits or tendencies marked by hostile dominance. The purpose of the present research was to contribute to an understanding of these gender differences. Four studies (total N?=?494 U.S. undergraduates) administered a modified animal preference test in which participants could choose to be predator or prey animals, but not labeled as such. Men were consistently more interested in being predator animals than women were, displaying a sort of hostile dominance in their projective preferences. Predator self-identifications, in turn, mediated gender differences in outcomes related to hostile dominance. Studies 1 and 2 provided initial evidence for this model in the context of variations in interpersonal arrogance, and Studies 3 and 4 extended the model to nonverbal displays and daily life prosociality, respectively. The findings indicate that gender differences in hostile dominance are paralleled by gender differences in preferring to think about the self in predator-like terms. Accordingly, the findings provide new insights into aggressive forms of masculine behavior.     

Diagnostic utility of the PTSD Checklist in detecting ptsd in Chinese earthquake victims

By using the posttraumatic stress disorder (PTSD) module of the Mini International Neuropsychiatric Interview (MINI) as the gold standard to identify PTSD, the current study investigated the diagnostic efficiency of the PTSD Checklist (PCL) as a screening questionnaire in a sample of 152 Chinese victims of the Wenchuan earthquake. The results showed that the area under the receiver operating characteristic (ROC) curve was .96 (SE = .02), and the optimally efficient cutoff score was 44. The findings provide preliminary support of the PCL as a screening questionnaire among Chinese earthquake victims. The present study may contribute to further PTSD-related research and practices in Chinese disaster settings.     

盲视与洞见——《荀子·非十二子》今读

《荀子·非十二子》顺应了当时天下学术总归一统的思想潮流,同时也以不容异己之势遮蔽了自身学术思想的好多问题。从历史的、辩证的角度看,荀子批判十二子的诸多论点盲视与洞见并存,与其自身的学术占位、理论体系和现实政治关怀密不可分。他的立论呈现出那个时代知识思想和政治权力难分彼此、相伴相生的原生态,并对后世知识分子言说与王朝政治产生了深远的影响。     

Contact and identity: The experience of ‘China goods’ in a Ghanaian marketplace

The rise in Chinese traders and increased availability of low‐cost imported goods benefits consumers, challenges local African retailers and is a point of tension in local communities. China's presence in Africa has been largely discussed and analysed through a political economy perspective. The social impact in local communities has been documented anecdotally but has yet to be empirically studied. This study took place in Makola Market, Accra, Ghana, to investigate the emerging intergroup encounters between established Ghanaian traders and nascent Chinese traders. Photo‐elicited semi‐structured interviews were conducted to explore how their interrelated experiences shape their interpretative framework and inform the dialectic of contact and social identity. I draw on these interpretative frameworks to propose a new model of contact, the Tri‐relational Contact Model, to capture and highlight how people's experiences include contact relationships with not just each other, but also with their places of business and the goods of trade. The findings from this study empirically highlight the micro‐level impact of China's presence in Ghana and help re‐conceptualize the contact hypothesis through a new model of contact with greater analytical utility to explicate the relational nature of contact and social identity formation.
