Teaching Basic Science and Clinical Medicine at a distance: An Evaluation of Satellite Communication
The evaluation plan arid preliminary results are reported for the ATS‐6 Satellite interactive telecommunication program for teaching at sites remote from an established medical school. The technical aspects of the system were seen as quite adequate and did not appear to substantially inhibit interaction. In the Fairbanks broadcasts analyzed, the average number of interactions ranged from 1.49 to 2.60 per minute. Ninety percent of the interaction flowed across the Satellite during Omak transmissions. Participants tended to initiate communication when they were on camera rather than when viewing their counterparts. Omak participants directed a higher percentage of the communication in student/resident programs (70%) than in faculty continuing education programs (59%). Interaction analysis indicated the categories of giving opinion, information, and suggestion were most frequent. Asking for opinion and suggestion occurred infrequently. The most frequent emotional expression was offering solidarity (e.g., reassurance), while there were exceedingly few expressions of disagreement, tension and antagonism. User acceptance of the system was determined to be very high. Participants with frequent exposure to the Satellite modality tended to have positive reaction. A significant difference in knowledge gain is reported in one of two basic science areas taught via Satellite as compared to regular instruction. 相似文献

Empirical analysis requires researchers to choose which variables to use as controls in their models. Theory should dictate this choice, yet often in social science there are several theories that may suggest the inclusion or exclusion of certain variables as controls. The result of this is that researchers may use different variables in their models and come to disparate conclusions with respect to predicted effects and their statistical significance. In such cases one is uncertain of which particular set of regressors forms the model that represents the data. The approach used below accounts for uncertainty in variable selection by using Bayesian model averaging (BMA). Accounting for uncertainty, we demonstrate that BMA provides better out-of-sample prediction for university graduation rates than results based on alternative variable selection methods. 相似文献

OBJECTIVE: This study was undertaken to examine whether alleged child sexual abuse perpetrators are handled differently by the courts than other alleged felony perpetrators. Comparisons were made from the time of prosecutorial case acceptance through prosecution to sentencing, with emphasis on judicial and prosecutorial decision-making and plea-bargaining. METHOD: Data were retrospectively abstracted on the entire defendant population of cases of sexual abuse of children and adolescents (ages 2-17) over a 5-year period. Using a case-flow analysis, comparisons were made between a child sexual abuse cohort and a cohort of matched felony cases from a single jurisdiction. RESULTS: Three important findings emerged. First, compared to other felons, abuse perpetrators were employed, had been married, were mostly European American, and were older than 30 years of age. Second, in the abuse cohort, as many as 14% had a previous sexual or violent record compared to 2% in the comparison group. Third, similar percentages of perpetrators in both groups were released on their own recognizance, had the charges against them dropped, and were found guilty. As well, no differences between groups were found in the proportion of individuals sentenced to jail, probation, counseling, or work release. CONCLUSIONS: Although the treatment of perpetrators of child sexual abuse was similar to the treatment of perpetrators of other felonies, the profile of the child abuse perpetrator was quite different. Knowledge about this profile may impact prosecution or treatment and recidivism rates, to the extent that recidivism is related to characteristics of the abuse perpetrator. 相似文献

This study examined the relationship between paternal roles, regardless of residence, and the well-being of 175 3-year-old children from low income, African American families. There were no differences in children's cognition, receptive language, behavior, or home environment related to father presence. Fathers (or father figures) were identified in 73% of the families, and 64% participated in an interview and videotaped observation. The relationships between paternal roles (parenting satisfaction, economic support, nurturance during play, child care, and household responsibilities) and children's cognitive skills, receptive language, behavior, and home environment were examined. After controlling for maternal age, education, and parenting satisfaction, there were significant relationships between paternal roles and each index of children's well-being, suggesting that fathers' contributions were unique. Fathers who were satisfied with parenting, contributed financially to the family, and were nurturant during play had children with better cognitive and language competence; fathers who were satisfied with parenting and employed, had children with fewer behavior problems; and when fathers were living with the child, the home was more child-centered. Neither the biological relationship of the father nor the parents' marital status entered into the models. These findings support ecological theories linking paternal involvement with children's well-being and argue for the institution of family-oriented policies that promote positive father involvement. 相似文献

This study investigated reasons for the omission of the torso typical in most young children's drawings of the human figure. Do they have an incomplete mental image of the human figure; if so will the torso be omitted from a manikin task too? As the head is normally drawn first, is the torso simply forgotten; if so will children include it if they are asked to draw the torso first? Eighty tadpole‐drawers (aged between 2 years 7 months and 5 years) were randomly allocated to a drawing or a manikin condition; they were further subdivided into a head‐first or torso‐first condition. Significantly more children produced a conventional figure when they constructed a manikin compared with those who were asked to draw; the order of body parts (head‐first vs torso‐first) had no significant effect. These results suggest that young children omit the torso from their human figures because they have yet to devise a way of drawing it, perhaps because it is a relatively unimportant item; there is little evidence that they have simply forgotten it or that their mental model for the human figure is incomplete. 相似文献

Information framing was investigated as a classroom management technique for academic task completion. Framing effect refers to the finding that people's choices are affected by how pre‐decisional information is framed (Tversky & Kahneman, 1984). In five 3rd and 4th Grade classrooms, teachers observed task completion rates of their students under five different framing conditions: unframed instruction; positively framed instruction with (a) group and (b) individual consequence; negatively framed instruction with (a) group and (b) individual consequence. Task completion rates were significantly greater under all framed instruction conditions than unframed, with effect sizes ranging from 0.21 to 0.32 and much greater at the class level. Improvement rates corresponding to effect sizes ranged from 20% to 70% at the class level, showing the usefulness of framing instructional directives. 相似文献

Little is known about the relative effects of post‐secondary learning services for students with learning disabilities. We compared outcomes for students with learning disabilities who selected to: (1) take an academic learning success course (course‐intervention), (2) have regular individual interventions (high‐intervention) or (3) use services only as needed (low‐intervention). Pre‐ and post‐test comparisons revealed improvements in academic self‐efficacy and academic resourcefulness for students in the course‐ and high‐intervention groups. The course‐intervention group also showed decreases in their failure attributions to bad luck and increases in their general repertoire of learned resourcefulness skills in comparison to the high‐intervention group and had significantly higher year‐end GPAs in comparison to the low‐intervention group. Here we find positive outcomes for students with learning disabilities taking a course that teaches post‐secondary learning and academic skills. 相似文献

To mark the 50th anniversary of Lamaze International, Childbirth Connection celebrates landmark accomplishments in education for childbearing women and families, and takes stock of the changing educational needs and preferences of current childbearing families in looking toward the future. Childbirth Connection's multi-year, multi-stakeholder Transforming Maternity Care initiative resulted in two landmark reports: 2020 Vision for a High-Quality, High-Value Maternity Care System and Blueprint for Action: Steps Toward a High-Quality, High-Value Maternity Care System. Selected recommendations of greatest relevance to the field of childbirth education are discussed, and the new Transforming Maternity Care Partnership is introduced. 相似文献

Over the past decade much has been written by journalists, policy makers, and academics, about young women's leisure time pursuits. A great deal of this interest has focused around a concern that teenage girls in the UK are taking up smoking in larger numbers than their male peers. This paper draws on findings from my small‐scale doctoral research into teenage girls' use of tobacco and alcohol in a town in southern England. I examine young women's use of cigarettes as an informal social currency, and as a way of thinking about such tobacco use beyond the deficit model of the young female smoker common to many drugs education interventions. In this paper I draw upon theoretical material from the social theories of exchange to explore how young women's reciprocal networks of cigarettes operate to underpin friendships and mobilise power within girls' social networks. I explore how smoking as a reciprocal gift‐giving practice supports and maintains friendship groups and particular gendered practices. My argument is that teen girls create and sustain bonds of friendship through their use and exchange of cigarettes. I want to suggest that within the girls' friendship groups, the flow of branded cigarettes as a resource highlights alliances, inter‐group rivalries, and provides space for the production and negotiation of teenage ‘cool’ femininities. 相似文献

This paper discusses retirement as a learning process, where learning, be it formal or informal, enables retirees to adjust to the transition from work to retirement. Such discussion is important given the fact that the world population is aging and that more people are retiring in the next few decades. Moreover, people are experiencing an increased length of retirement due to longer lifespan. Promoting the retirement experience as a productive learning process will bring huge social benefits to impact all involved, including the individual retirees themselves. Much early retirement research considered retirement as a monolithic event, which affects all retirees in similar ways, thereby justifying a cross-sectional approach to take a snapshot of the adjustment process. Such approach falls short of capturing the dynamic process that is characteristic of the retirement transition; and masks individual differences as retirees conceptualize, experience, and negotiate their own ways through the process of adaptation as it unfolds during the transition from work to retirement. This paper argues that in order to obtain in-depth understanding of the individual experiences in the retirement transition and to gain insight into the role of learning in the process, we need to use a qualitative, longitudinal approach to track and reflect the different patterns of change for retirees at different points in time. By examining the process of change and the retirement experiences of retirees using a longitudinal qualitative approach, we should be able to illustrate, how an individual learn to experience and adapt to retirement, so as to support the claim that the retirement process is unique and that learning is an integral part of that process. 相似文献
