In July 2001, the National Institute of Mental Health sponsored a workshop titled “Data Archiving for Animal Cognition Research.” Participants included scientists as well as experts in archiving, publishing, policy, and law. As is described in this report, the workshop resulted in a set of conclusions and recommendations concerning (A) the impact of data archiving on research, (B) how to incorporate data archiving into research practice, (C) contents of data archives, (D) technical and archival standards, and (E) organizational, financing, and policy issues. The animal cognition research community is encouraged to begin now to establish archives, deposit data and related materials, and make use of archived materials in new scientific projects. 相似文献
Stability and change of moral disengagement were examined in a sample of 366 adolescents from ages 14 to 20 years. Four developmental trajectories were identified: (a) nondisengaged group that started with initially low levels followed by an important decline, (b) normative group that started with initially moderate levels followed by a decline, (c) later desister group that started with initially high-medium levels followed by an increase from 14 to 16 years and an even steeper decline from 16 to 20 years, and (d) chronic group that started with and maintained medium-high levels. The results attest that adolescents who maintained higher levels of moral disengagement were more likely to show frequent aggressive and violent acts in late adolescence. 相似文献
In this paper we challenge traditional classroom reading and writing practices by presenting a critique of a critical literacy project that used hypermedia as the vehicle for textual engagement and resistance. We begin with remarks that locate critical literacy within a postmodern world, explain why we invited our students in the Faculty of Education at Memorial University of Newfoundland to read The Shipping News (1993), and continue with an analysis of their constructed World Wide Web texts. In addition to the Web pages, our data consist of students' commentaries on the course assignments, emails to the instructors, and the Internet audience's responses to the site. Literacy emerges and expands well beyond its earlier restrictive text-based practices. It assumes a plurality of constructions and meanings that are situated within social engagements with the world in which the students live. 相似文献
The "Online Updates" column generally focuses on bibliographic databases that may be licensed from commercial vendors or are available free of charge from a federal government agency. HazLit is featured because it is a unique and comprehensive resource of the literature of natural disasters. This column provides background information on HazLit and offers some searching basics, as well as highlights special information found at the Web site that hosts the database. 相似文献
This paper describes how early childhood teachers' incorporation of pauses raises the quality of talk-in-interaction during play-based mathematics activities. Responses of both children and teachers are shown to be more contingent and expansive when conversations include protracted pauses than during interactions in which pauses are largely absent. Pauses provided children with opportunities to initiate topics and facilitated more equitable access to discourse moves for children. By pausing before responding to a child's conversational gambit, teachers gained opportunities to assess children's demonstrated numeracy-related skills and understanding, and could thus provide authentic, individualised scaffolding. Pauses were not necessarily silent: a pause in an interaction with one child could be used strategically to model the learning interaction with a second child before returning to the first child in order to continue the discourse sequence. 相似文献
Purpose: The aims of this paper are to (1) evaluate the main factors influencing grazing system technology adoption among new entrant (NE) dairy farmers within Europe and the Irish pasture-based dairy industry, and (2) to determine the extent to which economic factors influence decision-making around technology adoption and use among NEs to the Irish dairy industry.
Methodology: Multivariate analysis is used to investigate the associations between region, education level, previous experience in dairy farming, herd size, age and the farmer's perception of the usefulness (PU) and ease-of-use of a technology (PEOU), and the likelihood of that technology being adopted.
Findings: The results of this study identify a high rate of grazing, artificial insemination (AI) and financial management technology adoption among NE dairy farmers whose technology decisions are primarily motivated by financial considerations and are closely related to the PU and PEOU scores of the technology. Grassland measurement had the lowest adoption rate (51%) compared to AI (86%) and farm financial management (84%).
Practical Implications: The substantial importance of PU and PEOU to technology adoption decisions indicates that future research, extension and education programmes should place increased emphasis on the benefits and usability of key technologies in addition to evaluating their scientific merit.
Originality/Value: For the first time information assessing technology adoption amongst new dairy farmers is available. This has the potential to improve and increase extension and education for new dairy farmers in a future post-quota environment. 相似文献
2 basic frameworks for lexical principles have been proposed (Golinkoff, Mervis, & Hirsh-Pasek; Markman). In many types of situations, these frameworks make the same predictions regarding 2-year-olds' interpretation of novel terms. However, the predictions diverge in some cases. 3 experiments were conducted to address 1 such situation: the case in which the child hears a novel term but already knows a label for each of the objects present. Results of all 3 studies converged on the same outcome: The new term was most likely to be treated as a second basic-level name for the category to which the object belonged. Analyses of individual patterns of responding revealed that, of the 58 subjects, 50 made more basic-level responses than part responses, 1 made equal numbers of basic-level and part responses, and 7 made more part responses than basic-level responses. Implications of these findings for models of early lexical development are discussed. 相似文献
