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
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84.
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

In light of growing concerns in the public and recent mandates from business program accrediting bodies and curricular task forces, the importance of teaching ethical topics in information systems programs is discussed. Innovative strategies used for teaching the application of ethical criteria to common situations are reviewed. Results of a survey of information systems faculty members in the US are presented and are compared to previous studies that related primarily to computer science and software engineering programs. Insight is provided into the topics, techniques, degree of coverage, and assessment techniques currently used when teaching ethics in computing-related programs. Key concerns and future work is also outlined. 相似文献

ABSTRACTA case study demonstrating how an online narrative featuring the adventures of a cuddly toy penguin, Pablo Penguin (@uoppenguin on Twitter) has been introduced at the University of Portsmouth Library to build trust and engagement between university students and library services and facilities. Evidence for the benefits of anthropomorphic brand mascots and best practice for their design and use to enhance the library brand, emotionally engage, build trust, lower barriers to service engagement, and mentor students from the perspective of a perpetual student are drawn from the marketing and psychological literature then illustrated in the case study. 相似文献
