The main purpose of the current study was to provide empirical evidence to support or refute assumptions of phenotypic deficits in motivation for children with Down syndrome (DS). Children with moderate intellectual disability (MID) associated with etiologies other than DS were recruited in an extension of a previous study that involved children with DS and typically developing children. The participants were 29 children with MID and 33 children with DS who were matched on mental age to 33 typically developing children, aged 3–8 years. Mastery motivation was assessed on task measures of curiosity, preference for challenge and persistence, as well as parental reports. There were no significant group differences on the mastery motivation tasks. Parental ratings of mastery motivation differed, with typically developing children generally being rated more highly than each of the disability groups. The view that motivational deficits are part of the DS behavioural phenotype was not supported.  相似文献

The study examined the moderating role of children's affect-biased attention to angry, fearful, and sad adult faces in the link between interparental conflict and children's distinct forms of involvement. Participants included 243 preschool children (Mage = 4.60 years, 56% female) and their parents from racially (48% African American, 43% White) and socioeconomically (median annual household income = $36,000) diverse backgrounds. Data collection took place in the Northeastern United States (2010–2014). Utilizing a multi-method, multi-informant, longitudinal design, attention away from anger selectively amplified the link between interparental conflict and children's subsequent coercive involvement (β = −.15). Greater attention to fear potentiated the pathway between interparental conflict and children's later cautious (β = .14) and caregiving involvement (β = .15). Findings are interpreted in the context of environmental sensitivity models.  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

Men's lacrosse and women's lacrosse share a name, but their histories differ. Both sports developed and became organised in close concert with the race, class and gender expectations of the eras. As a result, the sports began with rules that reflected those norms. Over time, the sports developed separately and generated unique forms, even as they sustained moments of interaction. Therefore, men's lacrosse and women's lacrosse are different sports. Using comparisons as the mode through which to view the sports, this article explores the organised beginnings of men's lacrosse and women's lacrosse to establish that the sports began and continued within identity-based norms. Through the discussion of the practical distinctions and critical understandings of the differences between the games, the author poses that these dissimilarities are relevant in considerations of the separate sports as they continue to change in the larger US sporting context. As sports such as basketball demonstrate, these arguments matter because broad-scale comparisons of women's sports to men's frequently render women's sport participants, and the sports they play, inferior. Notably, women's lacrosse participants also employed comparisons to distinguish and claim their history as unique from that of men's lacrosse. A comparative analysis highlights points of disjuncture between the sports and contextualises the importance of gender in the articulations of difference.  相似文献
