To date, theoretical and conceptual scholarship on anti-racism has been advanced through leading contributions from several disciplines (e.g., sociology, education, psychology). Still, there remain fewer empirical studies on anti-racism constructs, and we know little about the development of anti-racism among diverse youth across key stages of development. In this special section of Child Development, we sought to address this gap by highlighting scholarship in developmental science that attends to the development of anti-racism in children across contexts (e.g., families, schools) and developmental stages (e.g., early childhood through emerging adulthood). In our introduction to the special section, we review the collective contributions of included studies and outline recommendations for future research in the development of anti-racism in youth.  相似文献

This special issue spotlights the growing diversity of critical making practices in a range of disciplinary contexts both inside and outside of the academy, and begins to develop perspectives that will foster the emergence of critical making as a coherent field. On one hand, we see great value in incorporating material practices into existing information systems (IS) and science and technology studies (STS) research programs. In particular, forms of material engagement can help overcome the ineffectual linguistic bias of traditional critiques of technoscience. On the other hand, we believe that current material practices can benefit from the conceptualization of knowledge and social organization that are foundational to IS and STS research. In this introduction to the special issue we call attention to the mechanisms by which such practices may combine representational and material work to foster and support the development of new knowledge-making communities and institutions. We believe such work can serve as a framework for others engaged in critical making practices to better contextualize and expand the relevance of their work. We intend this special issue to serve as a “stake in the ground” for research on new forms of material-conceptual critique and their incorporation in the repertoire of critical technoscience scholarship.  相似文献

In laboratory medicine, several studies have described the most frequent errors in the different phases of the total testing process, and a large proportion of these errors occur in the pre-analytical phase. Schemes for registration of errors and subsequent feedback to the participants have been conducted for decades concerning the analytical phase by External Quality Assessment (EQA) organizations operating in most countries. The aim of the paper is to present an overview of different types of EQA schemes for the pre-analytical phase, and give examples of some existing schemes. So far, very few EQA organizations have focused on the pre-analytical phase, and most EQA organizations do not offer pre-analytical EQA schemes (EQAS). It is more difficult to perform and standardize pre-analytical EQAS and also, accreditation bodies do not ask the laboratories for results from such schemes. However, some ongoing EQA programs for the pre-analytical phase do exist, and some examples are given in this paper. The methods used can be divided into three different types; collecting information about pre-analytical laboratory procedures, circulating real samples to collect information about interferences that might affect the measurement procedure, or register actual laboratory errors and relate these to quality indicators. These three types have different focus and different challenges regarding implementation, and a combination of the three is probably necessary to be able to detect and monitor the wide range of errors occurring in the pre-analytical phase.  相似文献

The verbal disclosures of a Soviet spy masquerading as a university student are compared to those of three other group members involved in a semester‐long project. Audio‐tapes of six group meetings provide a unique opportunity to assess the relationship deception of this proficient deceiver. His communication is characterized by strategic disclosures designed to create a false impression and, thereby, to divert attention from his secret role. His conversation reveals more frequent control disclosures, attitude disclosures, personal disclosures, and dramatic disclosures than other group members. The spy also verbalized significantly more knowledge disclosures than all but one other peer. The frequency and content of his disclosures identify, in part, the communicative strategy of his disguise, whereby he drew considerable attention to himself and, thus, appeared transparent. The results underscore the importance of looking beyond the appearance of disclosures when attempting to identify relationship deception.  相似文献

你是爱,是暖,是希望,你是人间四月天 那些隐匿在黑暗中的云朵瞬间把太阳遮蔽,阳光从云朵里投射出来,映出云朵的轮廓,像一个模糊的幻境。云朵蘸满了墨水一样沉甸甸地粘在暗色的苍穹,欲来的雨云塞满了曾经湛蓝的天空。然后,雨水铺天盖地而来。  相似文献

The education of children with behavioural difficulties is under scrutiny from various quarters. The provision of specialised school environments isbeing questioned and, at the same time, there is pressure to minimise the exclusion of disruptive pupils. The study reported in this article lookedat a group of children whose behaviour had prompted placement in a school for emotionally and behaviourally disordered (EBD) pupils. The results showed the overall rate of psychiatric disturbance in the group was 86% and, in particular, that the rate of Attention Deficit Hyperactivity Disorder (ADHD) was 70%. These findings suggest that a significant minority of disruptive pupils may have their difficulties compounded by the presence of ADHD, and raises the question of whether specific screening processes should be established for such pupils.  相似文献
