It is shown that reinvestment and inventory effects can be described in 0431 0368 bond-graph terms. The associated differential equations in price and order-flow 0431 0368 V variables are bilinear forms. These effects are the fundamental inertia and compliance 0431 0368 V 3 of economic bond graph theory. Properties of the components and example market 0431 0368 V 3 graphs are discussed. 相似文献

OBJECTIVES: To investigate whether an information literacy programme for pre-registration nursing students at a UK higher education institution is effective in developing their skills and confidence: examines students' skill levels, factors affecting their confidence, and relationships between skills, confidence and demographic characteristics. METHODS: Quantitative and qualitative techniques were used: pre- and post-tests to measure changes in students' skills and self-assessed confidence levels after two key sessions in their first semester (n = 29); semi-structured interviews to explore factors affecting confidence (n = 5). RESULTS: Findings demonstrated positive impacts on skills and confidence. Key areas of skill development included: identifying journal articles, selecting search terms and evaluating website quality. Factors affecting confidence included: successful 'mastery' experiences in searching for information and the programme itself, especially small-group sessions, handouts and staff support. Evidence on links between skills, confidence and demographic factors was inconclusive. CONCLUSIONS: The study demonstrated the programme's effectiveness and identified areas for development, including the need to help students understand the relative merits of search engines and other sources. Evidence has contributed to a change in departmental policy, making attendance at sessions mandatory. Further studies have been recommended. 相似文献

Analytic Frameworks for Assessing Dialogic Argumentation in Online Learning Environments 总被引:3,自引:2,他引:1

Over the last decade, researchers have developed sophisticated online learning environments to support students engaging in
dialogic argumentation. This review examines five categories of analytic frameworks for measuring participant interactions
within these environments focusing on (1) formal argumentation structure, (2) conceptual quality, (3) nature and function
of contributions within the dialogue, (4) epistemic nature of reasoning, and (5) argumentation sequences and interaction patterns.
Ultimately, the review underscores the diversity of theoretical perspectives represented within this research, the nature
of dialogic interaction within these environments, the importance of clearly specifying theoretical and environmental commitments
throughout the process of developing or adopting an analytic framework, and the role of analytic frameworks in the future
development of online learning environments for argumentation.

The relationship between ageing and skills is of growing policy significance due to population ageing, the changing nature of work and the importance of literacy for social and economic well‐being. This article examines the relationship between age and literacy skills in a sample of OECD countries using three internationally comparable surveys. By pooling the survey data across time we can separate birth cohort and ageing effects. In doing so, we find that literacy skills decline with age and that, in most of our sample countries, successive birth cohorts tend to have poorer literacy outcomes. Therefore, once we control for cohort effects, the rate at which literacy proficiency falls with age is much more pronounced than that which is apparent, based on the cross‐sectional relationship between age and literacy skills at a point in time. Further, in studying the literacy‐age relationship across the skill distribution in Canada we find a more pronounced decline in literacy skills with age at lower percentiles, which suggests that higher initial literacy moderates the influence of cognitive ageing. 相似文献

The interest around intergenerational programs and the fostering of intergenerational relationships is growing internationally. However, studies on the profile and functions of intergenerational program managers are still scarce. Furthermore, available approaches to the traits and functions of intergenerational program managers have not highlighted which features are distinctive of these professionals. Through a Delphi study undertaken in Spain, with participation of 18 intergenerational program managers and 12 intergenerational specialists, consensus was reached around characteristics of both the general profile of intergenerational program managers and the specificities of this occupational role. On the one hand, being able to work on a team, having skills for observation and contextual analysis, and being skilled at managing resources were identified as the most important general characteristics. On the other hand, being good at promoting contacts, social relationships, interactions, and bonds was deemed to be the most distinctive feature of this profile. After contrasting our results with international guidelines and standards for intergenerational work, the need to develop and reinforce further the relational nature of this professional figure is argued. 相似文献

Abstract Rural communities need rural teachers who can “ground” traditional school subjects in local realities and dilemmas and at the same time fashion instructional approaches consonant with larger intellectual, ethical, and social purposes. Such teachers are assets rather than burdens to their communities. Only such teachers can cultivate an ethic of responsibility for the health and vitality of the communities of which they and their students are critical components. This essay examines the role of the university in professionalizing rural teachers. It contends that narrowly utilitarian ends prevail in teacher education programs, and that, in the absence of a substantive definition of educations public purpose, this instrumentalism creates teachers who are ill‐prepared to contribute in meaningful ways to the intellectual life of the communities in which they work. Teacher preparation programs should abandon the instrumental focus. Programs that prepare rural teachers, in fact, confront unique challenges and opportunities to include three themes at their centers: Sustainability, Social Justice, and Democracy. 相似文献

Stated learning objectives for final year projects tend to be fairly generic. As a result, individual students' experience of project work will depend heavily on the attitudes and beliefs of their supervisor. This paper questions the purpose of projects in the computing curriculum and proposes a personal theory of teaching through projects. In deciding whether such a personal theory should emphasize disciplinary specific content or an experiential approach to learning we consider teaching and learning as a process of enculturation. The personal theory of teaching proposed envisages projects as an opportunity for students to engage in realistic activity which allows them to learn something of the nature of the discipline. The student may be thought of as being on a journey, while the supervisor takes the role of a guide pointing out alternatives along the route but allowing students ultimately to find their own way. 相似文献
