This paper reviews the archival process at the Inter-university Consortium for Political and Social Research (ICPSR), a repository of digital social science data, and maps ICPSR’s Ingest and Access operations to the Open Archival Information System (OAIS) Reference Model. The paper also assesses ICPSR’s conformance with the archival responsibilities of “trusted” OAIS repositories, with the proviso that audit criteria for archival certification are still under development. The ICPSR to OAIS mapping exercise has benefits for the larger social science archiving community because it provides an interpretation of the reference model in the quantitative social science environment and points to preservation-related issues that may be salient for other social science archives. Building on the archives’ long tradition of shared norms and cooperation, we may ultimately be able to design a federated system of trusted social science repositories that provides access to the global heritage.

OBJECTIVE: To describe the development of the Cochrane Behavioral Medicine Field database of interventions and its contribution to the knowledge base of this field. METHODS: A list of behavioural medicine interventions was solicited from content experts. The resulting list of index terms was used to generate a comprehensive search strategy to retrieve relevant records, and a thesaurus of terms with which to index them. The records are included in a register. A subset of records have been coded for study design, health condition, intervention, study participants, setting and provider and made available in a public online database. RESULTS: The Cochrane Behavioral Medicine Field database consists of over 3500 records of systematic reviews, meta-analyses and randomized controlled trials for public educational use. CONCLUSIONS: The register provides a comprehensive listing of studies relating to behavioural medicine interventions. The public online database enables easy access to the evidence base and provides enhanced details of the studies included on it. These databases are a valuable resource for the behavioural medicine community. Other fields are encouraged to duplicate these methods in the design of content-specific databases.  相似文献

Although research has clearly established that low family income has negative impacts on children's cognitive skills and social-emotional competence, less often is a family's experience of material hardship considered. Using the Early Childhood Longitudinal Study, Kindergarten Class of 1998-1999 (N=21,255), this study examined dual components of family income and material hardship along with parent mediators of stress, positive parenting, and investment as predictors of 6-year-old children's cognitive skills and social-emotional competence. Support was found for a model that identified unique parent-mediated paths from income to cognitive skills and from income and material hardship to social-emotional competence. The findings have implications for future study of family income and child development and for identification of promising targets for policy intervention.  相似文献

Becoming a student teacher: core features of the experience   总被引:2,自引:2,他引:0  
This paper reports early findings of a longitudinal research project on the experiences of beginning teachers in England. In the first phase of the study (2003–2004), data were generated via: (1) in‐depth, face to face interviews with 85 student teachers throughout England; and (2) self‐completion questionnaires, returned by 4,790 student teachers across a range of initial teacher preparation (ITP) routes. Through these methods the study set out to explore student teachers' accounts of their motivations for entering ITP, their preconceptions and expectations of teaching and ITP, and their early experiences as student teachers. A number of general themes were found to cut across all of these areas, and are presented here as core features of the experience of becoming a student teacher. These relate to the concept of teacher identity, the role of relationships, the notion of relevance, and the central presence of emotion.

Cette étude décrit les conclusions préliminaires d'une recherche continue sur les expériences de ceux qui sont en train de devenir professeurs d'école en Angleterre. En première phase de l'étude (2003–2004), les données ont été recueillies par: 1) des entretiens approfondis en tête‐à‐tête avec 85 professeurs stagiaires dans toute l'Angleterre; et 2) des questionnaires, remplis eux‐mêmes par 4,790 professeurs stagiaires sur un échantillon de préparations initiales de professeur (PIP). Avec ces méthodes l'étude avait pour but d'explorer les explications des professeurs stagiaires concernant leur motivation pour entrer dans la PIP, leurs idées reçues et leurs attentes de l'enseignement et de la PIP, ainsi que leurs expériences initiales de professeur stagiaire. On a trouvé un nombre de thèmes généraux à travers tous ces domaines, et ceux‐ci sont présentés ici comme caractéristiques fondamentales de l'expérience vécue de professeur stagiaire débutant. Ils sont relatifs aux concepts suivants : l'identité du professeur, le rôle des relations, la notion de pertinence et la présence capitale de l'émotion.

Este documento es un informe sobre los primeros resultados de un proyecto de investigación longitudinal sobre las experiencias de profesores principiantes en la Inglaterra. En la primera fase del estudio (2003–2004), los datos fueron obtenidos a partir de dos fuentes: minuciosas entrevistas cara a cara con 85 profesores en prácticas por toda Inglaterra y cuestionarios personales que fueron devueltos por 4,790 profesores en prácticas procedentes de distintas ramas de la ITP (preparación para profesores principiantes). A través de estos métodos, el estudio fue lanzado con el propósito de sondear las razones que motivaron a los profesores en prácticas a entrar en la ITP, sus preconcepciones y expectativas en cuanto a la ITP y a dar clase y sus primeras experiencias como profesores en prácticas. Estas áreas presentaron una serie de temas generales comunes que son presentados aquí como características centrales de la experiencia de convertirse en profesor en prácticas. Estas están relacionadas con el concepto de identidad del profesor, la importancia de las relaciones, la noción de relevancia, y el papel central de las emociones.

Dieses Referat berichtet über die ersten Ergebnisse eines langfristigen Forschungsprojektes, basierend auf Erfahrungen von Lehrern in England, die in den Beruf einsteigen. In der ersten Phase der Studie (2003–2004) wurden Daten gesammelt mittels: 1) ausführlicher, persönlicher Gespräche mit 85 auszubildenden Lehrern aus ganz England; und 2) selbstauszufüllender Fragebögen, die von 4,790 auszubildenden Lehrern aus verschiedenen Ausbildungsrichtungen zurückgesendet wurden. Die Studie hatte das Ziel, die Berichte der auszubildenden Lehrer zu untersuchen hinsichtlich ihrer Motivation, eine Ausbildung anzufangen, ihrer Erwartungen vom Unterrichten und von der Ausbildung, sowie ihrer ersten Erfahrungen als auszubildende Lehrer. Eine Anzahl von allgemeinen Themen wurden in allen diesen Bereichen festgestellt und sind hier als Kernmerkmale des Ausbildungsverfahrens dargestellt. Diese beziehen sich auf das Konzept der Lehreridentität, auf die Rolle von Beziehungen, auf die Idee der Relevanz, sowie auf die zentrale Präsenz von Emotionen.  相似文献

Higher Education Institutions (HEIs) across the world have found themselves faced with new challenges on issues of ethics. Much of this has been centred on issues of assessment: plagiarism, buying essays, sharing/lending of previously passed work and the stealing of marked/returned work of others. Institutions still treat academic misconduct as largely a behavioural difficulty rather than an issue of ethics (or education), suggesting that academia places a far greater emphasis on combating new forms of dishonesty than it does on encouraging ethical habits and a healthy ethical environment. To date, the majority of research in this area has examined these forms of academic misconduct from the point of view of the student and/or the university, with the perspective of academics receiving very limited attention. Our hypothesis is that academics are perhaps best placed to provide the education needed to create and sustain an ethical environment, and we argue that being ‘ethically aware’ is a critical factor in the development of academic competence for all parties. This study adds to existing research in three ways: firstly, by highlighting the importance of an overall framework for an ethical environment within HEIs; secondly, by suggesting an ecological model of key parties (the university, students and academics) with responsibility for this environment in assessment; and thirdly, by including new evidence (generated by a survey of academics) to extend our understanding of their views on these issues.  相似文献

ABSTRACT

What role does academic development have to play in responding to radical cultural shifts in the global landscape? Whose voices and identities are contributing to institutional change? This reflective essay encompasses the perspectives of the four international panellists in the opening plenary of the International Consortium for Educational Development (ICED) 2018 conference in Atlanta, Georgia, USA – Torgny Roxå on ideologies; Chng Huang Hoon on agency and empowerment; Joy Mighty on voices and identities; and Mary Deane Sorcinelli on evidence and outcomes. These perspectives set the stage for the conference, and, brought together in this paper now, they address key conference themes, offer coordinates for reflection, and pose further questions about our profession.  相似文献

The University of Oklahoma College of Medicine has conducted an annual Anatomical Donor Luncheon where families of the anatomical donors met anatomy dissection groups of medical students. The luncheon presented an opportunity for donor family members to share the life story of their loved one with the medical students prior to the start of the anatomy course. This study was designed to understand the impact of the Anatomical Donor Luncheon on families of the donors. Seven families in two different focus groups were included to explore the reactions and attitudes of the donor families to meeting the medical students. Conversations were digitally recorded and transcribed. Qualitative analysis of textual data were coded by three investigators using the Constant Comparative Method. To provide evidence of validity, a form of member checking was utilized. For further triangulation, an analyst not involved in conducting the focus groups or analyzing the data, re-coded all data. This analyst used categories and themes identified by the original analysts, ensuring validity of the themes and any negative cases (data not supporting or contradictory of the established categories and themes). One meta-theme and three sub-themes were identified. The meta-theme was Donor Family Participants Experience Transformation and Closure, and sub-themes were Motivators for Participation, Optimal Venue Factors, and Optimal Medical Student–Anatomical Donor Family Interactions. Study findings indicated the Anatomical Donor Luncheon facilitated closure on the death of their loved one, and transformed their apprehension about the luncheon and body donation into an attitude of gratitude and appreciation.  相似文献
