Core structure of a〈100〉 superdislocations in a single-crystal superalloy during high-temperature and low-stress creep

A thorough TEM analysis has been carried out to study the dislocations cutting into γ′ phase in a single-crystal superalloy during uniaxial tensile creep under high-temperature and low-stress conditions. It is proved that the a〈100〉 edge superdislocation originates from the interfacial a〈100〉 dislocations and moves into the γ′ phase by pure climbing. And the dissociation of the a〈100〉 superdislocation core into two a/2〈101〉 superpartial dislocations during uniaxial tensile creep has been identified by HRTEM method for the first time.     

Cognitive Complexity in the Remote Association Test - Chinese Version

The remote association test (RAT) has been applied in various fields; however, evidence of construct validity for the original version and subsequent extensions of the RAT remains limited. This study aimed to elucidate the dimensionality and the relationship between item features and item difficulties for the RAT—Chinese Version (RAT-C) using the Rasch model and the linear logistic test model (LLTM). The revised 30-item RAT-C was administered to 475 undergraduates (263 women and 212 men) in 8 universities in Taiwan. Item features (including types of associations among stimulus words, and frequency and concreteness of target words) were recoded. The analysis found that the RAT-C measured a single latent construct, with all 30 items conforming to the Rasch model’s expectation. Furthermore, according to the LLTM analysis, most item features predicted Rasch item difficulty, suggesting that these features can explain why some items were more difficult than others and can be used to create new items with known item difficulty to tailor the difficulty level for different groups of participants in the future.     

Emerging Practices of Counseling and Psychotherapy in China: Ethical Dilemmas in Dual Relationships

A qualitative study was conducted with 48 Chinese counselors and psychotherapists who were interviewed in 2006 and an independent sample of 50 participants who responded to a survey in 2014. This study aims to explore how the new emerging expansion of mental health practice is related to issues and challenges of dual role relationship and how the well-engrained values and social characteristics of Chinese culture influences perceptions and resolution of ethical dilemmas. The participants identified similar dual relationships in 2006 and 2014: (a) Incidental boundary crossings, a sexual or romantic relationship, a dual social relationship, and a professional dual relationship were the most frequently reported types of dual relationships encountered by Chinese practitioners, and (b) the socioeconomic and cultural context and the development trajectory of counseling and psychotherapy in China play a significant role in shaping practitioners’ behaviors. The comparison of the data in 2006 and 2014 indicated that practitioners in psychotherapy and counseling have an improved awareness and understanding of ethical issues, evidenced by the decreasing cases of romantic and sexual relationships and increasing cases of social dual relationships influenced by the interrelatedness of traditional Chinese culture.     

Crossover of burnout from leaders to followers: a longitudinal study

The primary purpose of this 6-month two-wave longitudinal study among 104 Chinese leader–follower dyads is to investigate whether burnout could cross over from leaders to followers, and if so, whether this crossover process could be mediated by changes of followers’ job and personal resources. As expected, the structural equation modelling results show that after controlling for follower burnout at T1, leader burnout at T1 is negatively related to changes of followers’ job and personal resources over a period of 6 months, which in turn are negatively related to follower burnout at T2. Our longitudinal study has demonstrated that resource loss plays a mediating role in the crossover of burnout from leaders to followers. The implications of these findings for the intervention of burnout in the work context are discussed.     

We Can Make It Better: “We” Moderates the Relationship Between a Compromising Style in Interpersonal Conflict and Well-Being

Compromising is considered a useful strategy for solving interpersonal conflicts. However, compromising, which includes accommodating and sacrificing, may also lead to anxiety and depression. Therefore, the current study focused on a moderating mechanism between compromising and psychological health. Based on self-expansion theory, we hypothesized that the more individuals have a relational focus (i.e., a greater use of “we”) while narrating their compromising experiences, the better psychological health they will experience. Two hundred sixty-one participants from National Taiwan University (mean age = 20.40, 53.26 % male, 46.74 % female), wrote about an experience of conflict with their parents and completed a package of questionnaires to measure their conflict management style and psychological health. The frequency of the “we” pronoun was considered an index of relational focus. As predicted, the results from a hierarchical multiple regression demonstrated that “we” moderated the effect of compromising style on well-being. Specifically, the relationship between compromising and psychological well-being were strengthened for individuals who had more relational focus. Thus, although a compromising style helps solve interpersonal conflicts, it does not necessarily increase individuals’ well-being. How individuals anchor their experiences are more important.     

Effects of different packages on food product contagion: The moderating roles of mood states and product‐related information

Across two experiments conducted for this research, it is evident that different moderators do play a role in the influence of food product contagion effects. This research focuses on how mood states or product‐related information moderate contagion prime and package type. Existing studies indicate that unsealed packages can enhance the extent of the contagion effects more than sealed packages. Study 1 showed that happy people experienced stronger positive contagion effects than sad or neutral ones and that they also demonstrated stronger effects on unsealed packages compared with sealed packages. Conversely, sad people significantly enhanced the extent of negative contagion effects and experienced stronger effects on unsealed packages. Study 2, however, revealed that people receiving positive product‐related information experienced stronger positive contagion effects on unsealed packages, whereas people receiving negative product‐related information showed stronger negative contagion effects on unsealed packages. This is the first study to discuss the chosen moderators on the contagion effect. Copyright © 2015 John Wiley & Sons, Ltd.     

Multiple contest experiences interact to influence each other’s effect on subsequent contest decisions in a mangrove killifish

Many animals modify behavioural decisions based on information they have previously acquired. Contest behaviour is often affected by previous contest experiences: individuals behave more and less aggressively after a victory and defeat, respectively (winner/loser effect). Individuals in the field sometimes encounter multiple competitors in quick succession, but whether these experiences interact to influence each other’s importance is unclear. We tested five hypotheses for experience interaction (no interaction, retroactive interference, proactive interaction, reinforcement and diminishing returns) using Kryptolebias marmoratus. Focal individuals were paired up with opponents having the same 1-month contest outcome (1 month before the experiment), as this difference in actual or perceived fighting ability has been shown to affect the fish’s response to new experiences. We gave the focal individual of a pair a winning or losing experience on day 1. Then both fish of the pair received the same winning, losing or no-contest experience on day 2. Then we organised fights between the two. The effect of a day-1 losing experience did depend on the fish’s actual or perceived fighting ability: one-month losers readily showed loser effects from the day-1 losing experience, irrespective of the day-2 experience (i.e. no interaction between day-1 and day-2 experiences). One-month winners, however, only showed loser effects from a day-1 losing experience when the day-2 experience was also a loss (i.e. reinforcement). Day-1 winning experiences did not interact with day-2 experiences in 1-month losers or winners. Therefore, multiple experiences sometimes reinforce each other, but how they combine to influence behaviour depends on an individual’s actual or perceived fighting ability.     

An Application of the Complier Average Causal Effect Analysis to Examine the Effects of a Family Intervention in Reducing Illicit Drug Use among High‐Risk Hispanic Adolescents

The Complier Average Causal Effect (CACE) method has been increasingly used in prevention research to provide more accurate causal intervention effect estimates in the presence of noncompliance. The purpose of this study was to provide an applied demonstration of the CACE analytic approach to evaluate the relative effects of a family‐based prevention intervention, Familias Unidas, in preventing/reducing illicit drug use for those participants who received the intended dosage. This study is a secondary data analysis of a randomized controlled trial designed to evaluate the relative efficacy of Familias Unidas with high‐risk Hispanic youth. A total of 242 high‐risk Hispanic youth aged 12–17 years and their primary caregivers were randomized to either Familias Unidas or Community Practice and assessed at baseline, 6 months and 12 months postbaseline. CACE models were estimated with a finite growth mixture model. Predictors of engagement were included in the CACE model. Findings indicate that, relative to the intent‐to‐treat (ITT) analytic approach, the CACE analytic approach yielded stronger intervention effects among both initially engaged and overall engaged participants. The CACE analytic approach may be particularly helpful for studies involving parent/family‐centered interventions given that participants may not receive the intended dosage. Future studies should consider implementing the CACE analysis in addition to ITT analysis when examining the effects of family‐based prevention programs to determine whether, and the extent to which, the CACE analysis has more power to uncover intervention effects.     

Peer acceptance among Chinese adolescents: The role of emotional empathy,cognitive empathy and gender

Previous studies have found mixed results on the relationship between empathy and peer acceptance. Emotional and cognitive components of empathy were hypothesised to play different roles in peer acceptance, and the relationship between empathy and peer acceptance differed across genders. In this study, 375 Chinese adolescents completed self‐report measures of emotional and cognitive empathy. They also provided peer nominations that allowed for the determination of social preference and social impact scores. The results showed that a boy's cognitive empathy positively correlated with the extent to which he was liked by his male classmates, whereas a girl's cognitive empathy positively correlated with her social impact among her female classmates. This study suggests that empathy does not affect peer acceptance among adolescents uniformly; instead, gender plays a determinative role in the dialectics between social acceptance and empathy.
