The need for those working in a variety of settings to interact effectively with technical experts has grown dramatically in recent years as computers have become essential to the performance of an increasing broad range of professional work. This article presents a case of this sort of interprofessional interaction, exploring the process and outcomes of collaboration between technical professionals and educators working to bring Internet access to an urban public school district. Drawing on field note and interview data, the case reported here illustrates how differences in institutional routines and professional values can generate differing agendas, contrasting assumptions, and contrasting expectations concerning project products and outcomes among collaborators from different professional worlds. In the case we describe, these differences affected such central matters as the types and usefulness of technical resources to which users had access as well as users' confidence in the technology. The case also illustrates how aspects of this interprofessional conflict were addressed through an organizational change. The kinds of issues that arose in this project are likely to occur in a variety of professional settings; therefore, examination of this case provides insight into a variety of issues and dynamics that should be considered when embarking upon or analyzing any interprofessional collaborative effort, and particularly one that involves technical professionals.  相似文献

In their race to provide the ultimate guide to the moon, two 17th-century astronomers proposed lunar maps and nomenclatures that they hoped would gain international currency. But the names we use today were those proposed by the Jesuit, a friend of Galileo's persecutors, in a book whose purpose was to refute the Copernican system once and for all. We now believe that Riccioli was wrong about the universe, but why do we still use his nomenclature? The keys to this foundational visual debate in astronomical image-making are the moon maps themselves.  相似文献

OBJECTIVES: The objectives of this work were to identify the sources of information currently received, information-seeking behaviours, information requirements and preferences for future information provision amongst health and social care professionals providing care to children with health care needs. METHODS: Data were collected using a cross-sectional postal questionnaire survey. RESULTS: A wide range of information resources was reported as being available to professionals. However, a large proportion of respondents found it necessary to perform additional searches for information, suggesting that current resources were not satisfying their needs. The majority of professionals reported a preference for electronic formats, whilst a smaller proportion preferred hard copy materials. Participants promoted the use of informal networks as a means of support and exchange of information. CONCLUSION: Supplementing the information that is provided in electronic and hard copy formats, by enhancing informal networks, may be the most effective way of meeting the information needs of this group of professionals.  相似文献

WOMBAT is a software package for quantitative genetic analyses of continuous traits, fitting a linear, mixed model; estimates of covariance components and the resulting genetic parameters are obtained by restricted maximum likelihood. A wide range of models, comprising numerous traits, multiple fixed and random effects, selected genetic covariance structures, random regression models and reduced rank estimation are accommodated. WOMBAT employs up-to-date numerical and computational methods. Together with the use of efficient compilers, this generates fast executable programs, suitable for large scale analyses. Use of WOMBAT is illustrated for a bivariate analysis. The package consists of the executable program, available for LINUX and WINDOWS environments, manual and a set of worked example, and can be downloaded free of charge from http://agbu. une.edu.au/~kmeyer/wombat.html  相似文献

Stability in cardiac indicators before birth and their utility in predicting variation in postnatal development were examined. Fetal heart rate and variability were measured longitudinally from 20 through 38 weeks gestation (n = 137) and again at age 2 (n = 79). Significant within-individual stability during the prenatal period and into childhood was demonstrated. Fetal heart rate variability at or after 28 weeks gestation and steeper developmental trajectories were significantly associated with mental and psychomotor development at 2 years (n = 82) and language ability at 2.5 years (n = 61). These data suggest that the foundations of individual differences in autonomic control originate during gestation and the developmental momentum of the fetal period continues after birth.  相似文献

OBJECTIVE: The objective is to describe the prevalence of child sexual abuse (CSA) among women in New Zealand, document ethnic specific rates, and outline the frequency of abuse experienced and the most commonly identified perpetrators. Associations between CSA and later adverse consequences were also explored. METHODS: Retrospective report from a random sample of 2,855 women aged 18-64 years old in two regions in New Zealand. Face-to-face interviews with one randomly selected woman from each household were conducted. RESULTS: The overall prevalence rates for CSA were 23.5% for women from the urban region and 28.2% from the rural region. In both urban and rural regions, Māori women more frequently reported experiences of CSA than women from European and other ethnic groups (urban: 30.5% vs. 17.0% and rural: 35.1% vs. 20.7%). The median age of onset of the abuse was 9 years, and the median estimated age of the abuser was 30 years. Half of those who experienced CSA reported that it occurred once or twice, 27% "a few times," and 23% "multiple times." Sole perpetrators were involved in 83% of cases. The majority of cases were perpetrated by a family member, most frequently male. Compared with non-victims, victims of CSA were twice as likely to experience later intimate partner violence and violence by others. CONCLUSIONS: This study reports on a large, population-based sample in an ethnically diverse population in New Zealand, providing the first ethnic-specific rates of CSA available. Findings suggest important priorities for prevention and intervention activities.  相似文献

Far from all who complete teacher education end up working as teachers throughout their entire career. At first sight the value of teacher education, in terms of efficiency, seems to be a failure. In the present article we argue that teacher attrition, when defined as whether one is working as teacher or not, is a too blunt measure to gauge whether teacher education has been valuable. With a unique dataset, where we have detailed information on 87 Swedish teacher graduates’ working life across 23 years, we can consider whether activities and/or experiences point to an apparent use of teacher education. In conclusion, we find that in order to get informative estimates of its value it is important to consider it from different perspectives and to consider attrition related to the total working time spent in educational settings across a career rather than percentage leaving teaching after a set of years  相似文献

With a view to attracting more students and offering flexible learning opportunities, online teaching and learning is becoming increasingly widespread across the higher education sector. It is now found across a wide range of disciplines (e.g., business, health, psychology, accounting, information technology) and program levels (e.g., from associate degrees to doctorate degrees). Online delivery is also strongly represented in the teacher education sector at many universities. Research of online delivery in higher education generally and teacher education specifically has pointed to a range of benefits and challenges associated with this mode of learning. Within the teacher education literature, many aspects of the online preparation of teachers remain poorly understood. More specifically, there is scant literature on the experiences and beliefs of teacher educators in relation to their readiness and preparation for online teaching as well as their beliefs in relation to the appropriateness of online education for preservice teachers. This article responds to this gap in the literature and reports on an exploratory study that worked with academic staff, teaching in a fully online teacher education course, at a mid-size Australian university. Twenty-seven teacher educators completed a 34-item questionnaire that consisted of closed and open-ended questions. With regards to readiness and preparation for teaching online, the majority of teacher educators reported lacking confidence and competence in the technological and pedagogical skills required to teach online. By and large, the study participants were welcoming of individualized “at-elbow” support that seemed to abate some of their fears of online teaching. The teacher educators were generally divided on whether the online classroom was an appropriate method for preparing preservice teachers. This article concludes with several recommendations for consideration by teacher educators who work in an online environment and sets the stage for a more ambitious study.  相似文献

This article considers the involvement of schools and teachers in schemes which develop work with young offenders as an alternative to prosecution. Data from one such experimental scheme are presented and discussed. Issues are raised about the consequences of schools’ involvement in this kind of policy initiative which begins outside the educational system and entails co‐operation with professional workers in other statutory agencies. A central theme is whether a tightening of the welfare network in this way is unambiguously in the interests of young people.  相似文献
