This paper contributes to the increasing research on how experts within financial institutions co-produce and organize financial markets, and in particular how equity analysts enact stock markets characterized by high volume and volatility. The 20 equity analysts studied give qualitatively different accounts of what, from an outsider's perspective, appear to be very similar work. The analysts understand investment objects, equity markets, and what constitutes good analytical work in qualitatively different ways. This heterogeneity, or multiplicity, could be one source of the, unexplained by orthodox financial theory, ‘excess’ volatility and ‘excess’ trading volume on financial markets. Therefore, the paper complements accounts within heterodox finance theory and sociology-based studies of financial market activities. 相似文献

Background: University physics students were engaged in open-ended thermodynamics laboratory activities with a focus on understanding a chosen phenomenon or the principle of laboratory apparatus, such as thermal radiation and a heat pump. Students had access to handheld infrared (IR) cameras for their investigations.Purpose: The purpose of the research was to explore students’ interactions with reformed thermodynamics laboratory activities. It was guided by the research question: How do university physics students make use of IR cameras in open-ended investigation of thermal radiation as a phenomenon?Sample: The study was conducted with a class of first-year university physics students in Sweden. The interaction with the activities of four of the students was selected for analysis. The four students are males.Design and methods: We used a qualitative, interpretive approach to the study of students’ interaction. The primary means of data collection was video recording of students’ work with the laboratory activities and their subsequent presentations. The analysis focused on how IR cameras helped students notice phenomena relating to thermal radiation, with comparison to previous research on students’ conceptions of thermal radiation.Results: When using the IR camera, students attended to the reflection of thermal radiation on shiny surfaces, such as polished metals, windows or a whiteboard and emissive properties of surfaces of different types. In this way, they went beyond using the technology as a temperature probe. Students were able to discuss merits and shortcomings of IR cameras in comparison with digital thermometers.Conclusions: With the help of IR cameras, university physics students attend to thermal phenomena that would otherwise easily go unnoticed. 相似文献

This paper presents a systematic literature review of research focused on use of Semantic Web technologies in formal educational contexts. Through systematic search, the review has identified 199 research articles, which are examined with the intention of identifying prevalent themes within the body of research within the field of formal educational use of Semantic Web technologies. The themes identified by the review are: (1) Semantic Web ontologies; (2) Efficient distribution, accessibility, retrieval, reuse and combination of educational resources; (3) Linked Data; (4) Semantic Web enhanced virtual learning environments and personalization of learning environments; (5) Semantic Web learning objects; (6) Evaluation, feedback and assessment; (7) Semantic Web services; (8) Pedagogical tools for teachers and students. Furthermore, this review seeks to examine how these themes and the use of Semantic Web technologies in formal education reflects on the ongoing discussion of how pedagogy and technology should interact. The outset of this discussion is a previous study by Dirckinck-Holmfeld, which establishes that there is a tendency to emphasize technology over pedagogy in educational design and development. 相似文献

Public participation: democratic ideal or pragmatic tool? The cases of GM foods and functional foods
Over recent decades, public participation initiatives have been employed across Europe often with a focus on science and technology issues. In the area of new food technologies most participation initiatives have centered on genetically modified foods. By contrast, in the area of functional foods--where significant EU legislation was recently passed--we have seen no initiatives towards public inclusion. This applies also for Denmark, the country which is the focus of this article. Based on an interview study with members of the Danish parliament the article examines why such considerable differences exist between initiatives to involve the public, and it challenges the role that public participation plays in Danish politics. The main claim made in the article is that although politicians argue for the value and relevance of public participation their willingness to initiate participatory processes is overruled by their concern with playing by the rules of the political game. 相似文献

ABSTRACTA new methodology is proposed for qualitative discourse analysis (QDA) aimed at gaining enhanced insights into learning possibilities and indicators that arise during classroom group discussions. The constitution of this new methodology has two principle components: a discourse analysis approach that aims to identify the relationships between content and group dynamics; and a network analysis (NA) approach that uses the same data to identify meaning-related structural dynamics found in the data. The proposed methodology pairs these two components to create a supplementary iterative interchange that facilitates the attainment of greater analytic insights than are achievable by either of the two components individually. The critical aspects of the methodology are illustrated and discussed using real classroom data in ways that provide a procedural exemplar. The strengths and limitations of the proposed methodology are also discussed. 相似文献

Formative feedback currently receives attention as an effective means of increasing student learning. However, how to frame feedback to achieve the best effect is an ongoing debate. In this study we analyse a written data-set of 174 segments of teacher feedback and student response, coded using 10 emergent feedback and 14 response categories. As it is argued that feedback is a dialogue between students and teacher, links between feedback and response segments are viewed as a dialogical framework that we visualise and understand using network analysis. From this network we conclude that some ways of formulating feedback are more productive and likely to lead to types of responses that signify learning than others. We thus identify the reflection group of responses, consisting of the categories reflective response, explanation and students investigate own thinking. The feedback categories that link primarily to the reflection group are open question, wondering question and leading question, which we categorise as the questioning group of feedback. We discuss these patterns against a previously published framework, and by discussing specific examples we further our understanding of what makes feedback formative. 相似文献

While focus on quality in Danish higher education has been growing in recent years, limited attention has been devoted to developing and thoroughly validating instruments that allow collecting data about university students’ perceptions of the teaching-learning environment. Based on data from a large sample of Danish university students, a Danish version of the Learn questionnaire was validated using confirmatory and exploratory factor analysis. Analyses confirmed the existence of three scales reflecting students’ approaches to learning and six scales reflecting students’ perception of the teaching-learning environment. The results suggest that the Danish version of Learn is a valid instrument to be used for evaluation of the teaching-learning environment as well as for research into Danish university students’ learning strategies. 相似文献

The relation between types of tasks and the mathematical reasoning used by students trying to solve tasks in a national test
situation is analyzed. The results show that when confronted with test tasks that share important properties with tasks in
the textbook the students solved them by trying to recall facts or algorithms. Such test tasks did not require conceptual
understanding. In contrast, test tasks that do not share important properties with the textbook mostly elicited creative mathematically
founded reasoning. In addition, most successful solutions to such tasks were based on this type of reasoning. 相似文献
