Nanocellulose is an organic material envisioned to have the capacity to replace potentially harmful, non-renewable materials such as plastics. Before the material can be utilized commercially within the EU, its safety needs to be officially proven. This is envisioned to happen through the REACH chemicals regulation that controls the market entry of new substances. The regulation proposes concepts to support regulatory discretion and test methods to be used in risk assessments. While so doing, REACH puts forward assumptions pertaining to the critical qualities of innovations. However, when regulation is used to appraise radically new innovations, the assumptions need to be re-evaluated. Yet, analysis of expert accounts suggests that nanocellulose cannot be easily fit into the categorizations and analytical engagements that REACH proposes. For the purposes of a regulatory adoption, the problems are transformed into epistemological issues to be resolved through the incremental closing of knowledge gaps. Some of the key qualities of the material seem not to gain recognition in the regulatory realm that is in the making. At worst, the official strategy may create conditions for risks which the regulation is supposed to eradicate while, at the same time, hindering the development of plastic-substituting solutions.  相似文献

The most common method used to evaluate child behavior and functioning is rating scales completed by parents and/or teachers. Given that executive functioning (EF) plays a fundamental role in the developing child’s cognitive, behavioral, and social-emotional development, it would be ideal if ratings of EF and performance-based EF measures assess the same construct. However, most studies report a small to negligible association between performance-based measures and ratings of EF. There are few studies investigating this association for preschoolers, and most only include parent ratings. Teachers may be more reliable reporters of EF behaviors due to the higher demand for EF skills in the preschool setting than at home and because teachers may have a better sense of what behaviors are normative. In this study, we reviewed the associations between three EF rating scales completed by teachers on 243 preschool children. Results showed small to moderate correlations with EF measures of inhibition and cognitive flexibility/switching for all three scales, with the strongest associations observed between Child Behavior Rating Scale (CBRS) Behavioral Regulation subscale and child EF measures. Exploratory multivariate path analyses showed that, after controlling for age, sex, and socioeconomic status (SES), Behavioral Regulation significantly predicted performance-based measures of EF and accounted for incrementally more variance in the models. We conclude that in ideal situations, it is best to measure EF using both rating scales and performance-based measures of EF. The CBRS seems to be a sensitive measure of EF in preschoolers and may be a helpful brief screening tool for use with teachers.  相似文献

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.  相似文献

Empathy has great effect on human well‐being, promoting healthy relationships and social competence. Although it is increasingly acknowledged that infants show empathy toward others, individual differences in infants’ empathy from the first year of life have rarely been investigated longitudinally. Here we examined how negative reactivity and regulation, two temperament traits that predict empathic responses in older children and adults, relate to infants’ empathy. Infants were studied at the ages of nine (= 275) and 18 (N = 301) months (194 infants were studied at both ages). Empathic responses were assessed by infants’ observed reactions to an experimenter's simulated distress. Negative reactivity (fear, sadness, and distress to limitations) and regulation (soothability and effortful control) were assessed by parental reports. Negative reactivity was also examined by infants’ observed reactions to an adult stranger (fear) and during interaction with their mothers (displays of sadness/distress). When examined cross‐sectionally, infants’ fear and distress to limitations associated with self‐distress in response to others’ distress. In contrast, when examined longitudinally, early sadness and distress to limitations, but not fear, associated with later empathic concern and inquisitiveness. Moreover, this longitudinal relation was moderated by infants’ soothability and was evident only for children that had high soothability by the later time‐point. Our findings suggest that infants who at an earlier age show negative reactivity, react later in development with more empathy if they achieve sufficient regulation abilities. By that, the findings stress the developmental nature of temperament–empathy relations during infancy.  相似文献

本研究通过成语匹配任务启动情绪调节目标,在情绪flanker任务中考察了自动情绪调节启动对注意偏向的影响。结果表明,中性启动条件下,被试表现出对负性情绪面孔的注意偏向,而情绪调节启动条件下,被试对正性、负性情绪面孔的注意分配不存在显著差异。这一结果说明自动情绪调节可以有效地减弱被试的负性情绪面孔注意偏向。  相似文献

External violences are the violences exerted against an employee on his workplace. The phenomenon constitutes an increasing risk, in particular for the employees in relation with a public. This article presents a research undertaken within a social structure, worked out starting from problems which relate to the identification of external violences, perceptions and reactions located of the agents in daily relation with users; starting from a collection of data resulting from interviews and observations on three sites. The article points the multi-determined character of violences and the strategies put in work by the agents to cope with it. In that, he questions the phenomenon within the organizations of service in link with the complexity of the situations of the users.  相似文献

为了考察实验室指导性与个体习惯性情绪调控策略对恐惧反应的影响,先使用问卷调查了81名大学生的习惯性重评与抑制水平,随后将被试分为两组,指导其在条件化恐惧习得过程中进行主动的情绪调节或自然观看,24h后进行恐惧的表达测试。结果发现,习惯性抑制水平与恐惧习得及表达水平呈显著负相关,且指导性情绪调节与习惯性抑制均显著降低了恐惧习得及表达水平。这提示指导性与习惯性情绪调节策略均能够削弱应激的伤害以保护个体。  相似文献

积极情绪的二态表达(the dimorphous expressions of positive emotion;DEPE),指当个体处于强烈的积极体验时,这种积极体验不仅诱发了与之相对应的积极表达,而且伴随着消极的外显表现,喜极而泣便是其中的典型。DEPE蕴含了一般情绪现象产生的基本过程,但又和其他情绪现象(如,"悲喜交加"和"乐极生悲")具有本质性区别。未来研究可以运用各类新近技术,进一步细化和完善其理论模型,从不同视角考察影响DEPE产生的因素,并探讨DEPE中消极表达在人际间所起到的功能及其机制。  相似文献

采用空间提示任务,研究经期不同时段女大学生负性情绪对选择性注意抑制的影响及有效的情绪调节策略。实验1选取黄体中后期与月经期女大学生各32名,使用视频材料诱发中性和负性情绪,结果发现黄体中后期被试选择性注意抑制能力显著低于月经期;实验2选取104名黄体中后期的女大学生,负性情绪诱发后分组采用沉思、分心与人际策略进行调节,结果表明三种策略均降低了个体负性情绪,提高了选择性注意抑制成绩。研究结论如下:黄体中后期女性更受负性情绪影响,注意抑制能力下降,但有效的调节策略可改善其负性情绪并提高注意抑制能力。  相似文献
