A comparison of blood pressure in term, low birth-weight infants of smoking and nonsmoking mothers

Infants exposed to the components of cigarette smoke in utero are at an increased risk for perinatal death, low birth weight, sudden infant death syndrome, and premature delivery. The purpose of this pilot study was to compare blood pressure values in term low-birth weight infants (相似文献   

Integrating technology in a field-based teacher training program: The PT3@ASU project

The Preparing Tomorrow’s Teachers to Use Technology (PT3) initiative has funded various efforts to improve and enhance the technology preparation of preservice teachers. At Arizona State University, these efforts have focused on providing preservice teachers with opportunities to develop, implement, and evaluate their own instructional activities that utilize technology effectively and appropriately in authentic situations, to give them the myriad of tools necessary to integrate technology into teaching and learning activities. This paper focuses on the integration of these efforts into the field-based elementary education program, and discusses our formative evaluation of the field-based technology integration model, through the following questions: What are the preliminary successes of the model with regard to student perceptions, attitudes, and integration of technology into instructional activities? and What components of the model require additions or modifications?     

The neuroscience of perceptual categorization in pigeons: A mechanistic hypothesis

We are surrounded by an endless variation of objects. The ability to categorize these objects represents a core cognitive competence of humans and possibly all vertebrates. Research on category learning in nonhuman animals started with the seminal studies of Richard Herrnstein on the category “human” in pigeons. Since then, we have learned that pigeons are able to categorize a large number of stimulus sets, ranging from Cubist paintings to English orthography. Strangely, this prolific field has largely neglected to also study the avian neurobiology of categorization. Here, we present a hypothesis that combines experimental results and theories from categorization research in pigeons with neurobiological insights on visual processing and dopamine-mediated learning in primates. We conclude that in both fields, similar conclusions on the mechanisms of perceptual categorization have been drawn, despite very little cross-reference or communication between these two areas to date. We hypothesize that perceptual categorization is a two-component process in which stimulus features are first rapidly extracted in a feed-forward process, thereby enabling a fast subdivision along multiple category borders. In primates this seems to happen in the inferotemporal cortex, while pigeons may primarily use a cluster of associative visual forebrain areas. The second process rests on dopaminergic error-prediction learning that enables prefrontal areas to connect top down the relevant visual category dimension to the appropriate action dimension.     

Encouraging transformation and action competence: A Theory of Change evaluation of a sustainability leadership program for high school students

Abstract

Make a Difference (MAD) is a sustainability leadership program for high school students in Auckland, New Zealand. It offers a residential camp and follow-up activities. This article documents a participatory, utilization-focused evaluation of MAD, based on a Theory of Change approach. We ran workshops with MAD coordinators and students and conducted a survey with previous participants. This identified the core developmental and action outcomes of MAD, and the role of transformation and action competence in inspiring change. We discuss the benefits and limitations of both MAD and our evaluation approach and offer recommendations for others working on youth sustainability programs.     

Developing an HIV/AIDS Education Curriculum for Takalani Sesame, South Africa's Sesame Street

The HIV/AIDS pandemic in South Africa has prompted a need for extensive efforts to educate citizens of all ages about the disease and ways of coping with its impact. This paper describes the process of developing an HIV/AIDS education curriculum for Takalani Sesame, an educational media project for young South African children. The process began with formative research with adults and children, and extensive discussions with HIV/AIDS health specialists. Guided by the research and advice from specialists, a team of educators developed a comprehensive curriculum that the Takalani Sesame production team will use to create HIV/AIDS education messages for television, radio and outreach materials for children ages 3-7 and the adults who care for them.     

Teaching business ethics in the global South: control,resistance, and phronesis

We explore academic literature on business ethics education and critically compare the themes emerging from different contexts. Outlining guidelines for analysis based on Southern Theory, we conduct a content analysis on a selection of English, peer-reviewed articles and then critically compare emergent themes from across the ‘Northern'–Southern’ divide. The results suggest commonality but also substantive nuances. One key difference concerns a concerted effort from the South to decipher daily business experiences in relation to prevalent business ethics frameworks focused on the North. Furthermore, using notion of phronetic science, we critically discuss our findings to highlight inherent dynamics of control and resistance. The paper concludes by suggesting future directions for business ethics curriculum development that is more sensitive to these dynamics and by suggesting an adoption of notions related to practical wisdom.

Continuing evolution: The Rhode Island early childhood summer institute

Abstract

This narrative chronicles the continued evolution and development of the Rhode Island Early Childhood Summer Institute, an intensive 5‐day inservice professional development program designed for educational leaders from various sectors of the early care and education field. The goal is to review the continued use of successful practices implemented in the 1993 through 1997 programs and to highlight new programmatic features that were introduced in the most recent 2000 and 2001 programs. The Rhode Island Early Childhood Summer Institute program may serve as a model to others responsible for designing inservice professional development experiences to enhance the capacity of the early childhood workforce.     

Teachers and students' divergent perceptions of student engagement: recognition of school or workplace goals

In extant research, the concept of student engagement refers to individual behavioural patterns and traits. Recent research indicates that engagement not only should be related to the individual but also should be anchored in the social context. This ethnographic field study of students and teachers in a Danish vocational education and training school responds to the need for more knowledge on this theme by exploring the social dynamics of engagement perceptions. Results show that teachers and students held diverging perceptions of student engagement that rested on educational goals as well as goals related to the perceived future work settings. The misrecognition of the students' perception of engagement had direct negative consequences for student performance and school attachment. The implications of the findings are discussed in detail.
