Building up resources in the relationship between work–family conflict and burnout among firefighters: moderators of guanxi and emotion regulation strategies

This study investigated the moderating effects of supervisor–subordinate “guanxi” alongside relevant emotional regulation strategies, including cognitive reappraisal and expressive suppression, undertaken by 402 firefighters experiencing burnout caused by work–family conflict, as revealed through the application and analysis of the job demands–resources model. According to the regression model for the moderating effects, high levels of supervisor–subordinate guanxi may improve the relationship between work–family conflict and burnout, while frequent suppression of expressivity may enhance this relationship. Moreover, when supervisor–subordinate guanxi is high, cognitive reappraisal may effectively mitigate the relationship between work–family conflict and burnout. To this end, both guanxi and cognitive reappraisal are crucial for supporting emotional regulation in the workplaces of ethnic Chinese societies.     

Migration patterns,family functioning,and life satisfaction among migrant children in China: A mediation model

There are three distinct patterns of migration among Chinese migrant children: whole‐family, single‐parent‐first, and both‐parents‐first migration. This study investigated the life satisfaction of children who migrated under the different migration patterns and examined the mediating role of family functioning in the relationship between the children's migration patterns and their life satisfaction. Participants consisted of migrant children (N = 703) from primary and junior middle schools in Chengdu, China. The results showed that (a) migrant children from the whole‐family and single‐parent‐first patterns of migration reported greater life satisfaction than did those from the both‐parents‐first pattern, and (b) family functioning partially mediated the association between migration patterns and life satisfaction. The present study highlights the importance of avoiding separation of children from both parents during migration and the need to develop interventions for migrant children's psychological adaptation by improving their families’ functioning.     

时间洞察力对成瘾行为的影响及其机制

成瘾行为给个体和社会带来了严重的危害。对成瘾人群时间洞察力的研究成为探讨成瘾行为产生和发展的一个新的视角。过去消极、现在享乐和现在宿命时间洞察力取向的个体更可能出现成瘾行为, 而未来时间洞察力取向则是成瘾行为的一个保护性因素, 它不仅可以减少成瘾行为的发生, 也有利于成瘾行为的康复。从自我调节, 冲动性决策等行为机制和前额叶的神经机制方面可以帮助我们深入理解时间洞察力对成瘾行为的影响。未来研究可以进一步探讨不同成瘾行为者时间洞察力的一致性与特异性; 采用纵向研究方法探讨成瘾者时间洞察力的动态变化过程; 对成瘾者的洞察力进行干预, 增加成瘾者的未来时间洞察力, 减少其过去消极和现在时间洞察力取向来帮助成瘾者实现时间洞察力的平衡, 从而提高其戒断效果。     

Timing in a dual-task in children and adults: when the interference effect is higher with concurrent non-temporal than temporal information

This study used a dual task with participants of different levels of cognitive capacities, assessed with neuropsychological tests, to examine the attentional cost on time judgment of processing concurrent temporal and non-temporal information. Children and adults performed a temporal reproduction task with either an interfering temporal or non-temporal discrimination task. The results showed an underestimation of time in the dual task compared to the single task, the extent of which was directly linked to individual attentional capacities. However, the non-temporal task interfered more than the temporal task on the reproduced durations. Nonetheless, the temporal reproduction task equally affected performance in the non-temporal and the temporal discrimination task. These results reveal the predominant role of the cost of dual-tasking in interference effects on time judgment, and the lesser role of concurrent information, especially of temporal information. This suggests a lack of competition for attentional resources in the processing of multiple durations.

Univariate and multivariate skewness and kurtosis for measuring nonnormality: Prevalence,influence and estimation

Nonnormality of univariate data has been extensively examined previously (Blanca et al., Methodology: European Journal of Research Methods for the Behavioral and Social Sciences, 9(2), 78–84, 2013; Miceeri, Psychological Bulletin, 105(1), 156, 1989). However, less is known of the potential nonnormality of multivariate data although multivariate analysis is commonly used in psychological and educational research. Using univariate and multivariate skewness and kurtosis as measures of nonnormality, this study examined 1,567 univariate distriubtions and 254 multivariate distributions collected from authors of articles published in Psychological Science and the American Education Research Journal. We found that 74 % of univariate distributions and 68 % multivariate distributions deviated from normal distributions. In a simulation study using typical values of skewness and kurtosis that we collected, we found that the resulting type I error rates were 17 % in a t-test and 30 % in a factor analysis under some conditions. Hence, we argue that it is time to routinely report skewness and kurtosis along with other summary statistics such as means and variances. To facilitate future report of skewness and kurtosis, we provide a tutorial on how to compute univariate and multivariate skewness and kurtosis by SAS, SPSS, R and a newly developed Web application.     

Estimating group size from human speech: Three's a conversation,but four's a crowd

Much previous research has examined various aspects of auditory processing, including the localization of sounds, and the influence of lexical and indexical information on language processing. In the present set of experiments we explored the ability of listeners to estimate the number of speakers in a group solely from the information in an auditory signal. The bound on accurately estimating the number of simultaneous speakers is 3. We suggest that subitization—the ability to estimate numerosity of visual and auditory elements without explicitly counting these elements—rather than the capacity of short-term memory, may underlie this limitation. The cognitive constraint on estimating the number of simultaneous speakers may have implications for a wide variety of seemingly unrelated psychological phenomena.     

Semantics and the sacred

ABSTRACT

This article looks at four different scholarly perspectives on ‘sacred’ – the ineffable sacred, the experienced sacred, the polarized sacred and the contextualized sacred – in order to draw out their implicit presuppositions about meaning. The first two stances presuppose that meaning depends on what bits of language are about (referentialism), and the other two stances presuppose that meaning depends on relations between bits of language (holism). The article concludes three things: these prominent views of ‘sacred’ rest on usually implicit or unrecognized assumptions about the nature of meaning; some of those assumptions explain why certain theories are contentious and problematic and others ground more promising and productive approaches.     

New polytypes of long-period stacking ordered structures in a near-equilibrium Mg97Zn1Y2 alloy

By atomic-scale high-angle annular dark-field scanning transmission electron microscopy, the long-period stacking ordered (LPSO) structures in a near-equilibrium Mg₉₇Zn₁Y₂ (at.%) alloy have been characterised. In addition to 18R and 14H, new polytypes of LPSO structures are analysed and determined as 60R, 78R, 26H, 96R, 38H, 40H, 108H and 246R. All of these LPSO structures feature AB′C′A building blocks with two Mg layers and three Mg layers sandwiched between them. The Bravais lattices and space groups of new polytypes of LPSO structures were easily determined via the newly introduced method. A structural relationship between the LPSOs is proposed.     

A first-principles study of the formation of θ′′ phase in Al–Cu alloys

The θ′′-Al₃Cu phase plays an important role in the precipitation process of Al–Cu alloys. This phase has a sandwich structure—every two {200}_Cu layers are separated by three {200}_Al layers. To analyse the formation mechanism of this structure, the elastic strain energy of the {200}_Cu and {200}_Al layers, and the chemical bonding energy that reflects the interaction between the electrons in Cu and neighbouring Al atoms are calculated and analysed by first-principles calculations, projected density of states and Bader analysis. Our computation results reveal that this sandwich structure is energetically preferred in the competition of elastic strain and chemical bonding energies. To minimise the elastic strain energy of {200}_Al and {200}_Cu layers, the {200}_Cu layers prefer being apart from each other, whereas the chemical bonding energy favours the opposite arrangement because the intermetallic bond between Al and Cu atoms may form through p-d hybridization.
