Two Lagrange multiplier (LM) methods may be used in specification searches for adding parameters to models: one based on univariate LM tests and respecification of the model (LM‐respecified method) and the other based on a partitioning of multivariate LM tests (LM‐incremental method). These methods may result in extraneous parameters being included in models due to either sampling error or the model being misspecified. A 2‐stage specification search may be used to reduce errors due to misspecification. In the 1st stage, parameters are added to models based on LM tests to maximize fit. Second, parameters added in the 1st stage are deleted if they are no longer necessary to maintain model fit. Illustrations are presented to demonstrate that errors due to misspecification occur with the LM‐respecified method and are even more likely with the LM‐incremental approach. These illustrations also show how the deletion stage can help eliminate some of these errors. 相似文献

Multiple perspectives regarding the definition of quality child care, and how child care quality can be improved, were examined using a focus group methodology. Participants were representatives from stakeholder groups in the child care profession, including child care center owners and directors (3 groups), parents (3 groups), child caregivers (3 groups), policy makers (1 group), and social service providers (1 group). Qualitative analysis revealed 6 components of quality that were consistently discussed across all participant groups: (a) communication and rapport, (b) caregiver practices, (c) staff characteristics, (d) finances and resources, (e) visibility and involvement, and (f) professionalism. Analyses highlighted differences among stakeholder groups and the complex interplay among quality components. Findings are compared to previously documented perspectives on child care quality, and a conceptual model is presented that (a) summarizes findings about how proximity to child impacts definitions of quality and (b) highlights the central role played by child care center directors. Implications for child care practice and policy are discussed. 相似文献

ABSTRACT This paper examines the social construction of ‘fashionability’ – namely, what is ‘desirable’ and ‘fashionable’ – with reference to the concept ‘cultural mediators’ that foregrounds agency, negotiation and the contested practices of market actors in cultural production. It zeroes in on the cultural mediators’ attitudes and positions in the two markets by drawing on 25 in-depth interviews with industry veterans. It shows that the mediators in South Korea and China increasingly occupy hybrid occupational roles and social positions across industries and sectors yet achieve limited success in countering the status quo of Western fashion through mediation. The analysis contributes to the literature with a categorisation of seven mediation practices that shape the valuation of fashion products (i.e. ‘fashionability’) in two ways. Empirically, this categorisation illuminates how cultural mediators make reference habitually to the broader social and cultural contexts to co-construct cultural-aesthetic objects. Theoretically, it advances a cultural-economic approach to the understanding of cultural mediation and challenges the reductionist viewpoint of actor–network theory through the notion of a matrix of cultural-economic agency. 相似文献

ABSTRACT
Background and Context
Sports and technology are often pitted as being at odds with one another. While there are several educational activities that make reference to sports we seldom see sports used as an authentic context for learning computing. 相似文献65.
Alcohol-related posts on social-networking sites (SNS) can damage college students’ reputations and relationships and contribute to risky behavior. However, little is known about how college drinkers engage in privacy management involving alcohol content. Through 48 interviews and a Communication Privacy Management lens, this study uncovered criteria on which students relied to develop relatively impermeable boundaries around alcohol posts, the ways they collectively negotiated privacy with peers, and how participants implicitly and explicitly communicatively negotiated privacy turbulence. Findings suggest important connections between the co-occurrence of online privacy management and identity management, including how facework is involved in remediating privacy breaches and the co-opting of privacy. Findings also inform efforts to educate college drinkers about on-and-offline strategies to manage alcohol-related SNS content. 相似文献

In Science and the Modern World, Alfred North Whitehead (1925/1953) critically discusses the historical development of science and its larger impact on our civilization and culture today. The fallacy of misplaced concreteness (FMC) is a notion central to his analysis, both of the process of inquiry and to the general sustainability of quality of life. This paper is part of a panel of four presentations relevant to the theory, practice, and teaching of science. In this paper I identify the FMC as a set of variations on the central theme of misplacing concreteness, by mistaking the abstract for the concrete, and I define the component notions involved. More than half of the paper involves a representative range of concrete examples of the FMC. The realm of the aesthetic, of patient and sensitive attention, the full range of immediate bodily feeling, and the variety of real values revealed therein, turns out to be both the victim of and the remedy for the FMC. As Whitehead says: "Sensitiveness without impulse spells decadence, and impulse without sensitiveness spells brutality" (1925/1953, p. 200). 相似文献

Increasingly, metadata standards have been recognized as constructed rather than neutral. In this article, we argue for the importance of a documentation approach to metadata standards creation as a codification of this growing recognition. By making design decisions explicit, the documentation approach dispels presumptions of neutrality and, drawing on the “wicked problems” theoretical framework, acknowledges the constructed nature of standards as “clumsy solutions.” 相似文献

This paper reports on a study that explored issues of curriculum continuity at the school to university level transition in Malawi. It bases its analysis on the school integrated science curriculum and university science and technology programmes. Data were collected through interviews, documentation and classroom observations. The findings show that gaps do exist, with both the ‘intended’ and the ‘experienced’ curriculum, between integrated science and the requirements of university science and technology programmes in the three categories of the knowledge of science, science as a way of knowing and general knowledge and skills. With respect to the investigative nature of science, gaps exist only with the delivered curriculum. Implications for both the integrated science curriculum and the university science and technology programmes are discussed. 相似文献

Twenty five class teachers completed a "Strengths and Difficulties" assessment for 523 children aged from 7 to 11 years of age. Children self-completed a 39-item "My Life in School" questionnaire. One third of the sample were self-reported victims of bullying behaviour. Boys with poor prosocial skills, emotional problems and general difficulties with social interaction, expression of emotion and hyperactivity were at greatest risk of being bullied. There was no significant effect of age. The data support previous research findings that gender influences the prevalence of bullying but not that younger children are more vulnerable. This study provides new evidence that teachers recognise social behaviour and interactions that can significantly affect whether primary school children are bullied. 相似文献

This study examined whether childhood interparental conflict moderated the mediational pathway involving adolescent exposure to interparental conflict, their negative emotional reactivity to family conflict, and their psychological problems in a sample of 235 children (Mage = 6 years). Significant moderated-mediation findings indicated that the mediational path among Wave 4 interparental conflict during adolescence, change in youth negative reactivity (Waves 4–5), and their psychological problems (Waves 4–6) was significant for teens who experienced low, rather than high, levels of childhood interparental conflict (Waves 1–3). Supporting the stress sensitization model, analyses showed that adolescents exposed to high interparental conflict during childhood evidenced greater increases in negative reactivity than their peers when recent parental conflicts were mild. 相似文献
