This paper argues that contemporary workplaces give rise to many different forms of knowledge creation and use, and, as a consequence to different forms of learning and pedagogical approaches. Some of these are utilised to the benefit of the organisation and employees (though not, necessarily, in a reciprocal manner), but others are buried within everyday workplace activity. The discussion builds on earlier work where it was argued that organisations differ in the way they create and manage themselves as learning environments, with some conceptualised as ‘expansive’ in the sense that their employees experience diverse forms of participation and, hence, are more likely to foster learning at work. By studying the way in which work is organised (including the organisation of physical and virtual spaces), this research is suggesting that it is possible to expose some of this learning activity as well as to identify examples where new (or refined) knowledge has been created. In this regard, it is argued that it is important to break down conceptual hierarchies that presuppose that learning is restricted to certain types of employee and/or parts of an organisation and to re‐examine knowledge as applied to the workplace. The conclusion focuses on how such an approach, and in particular the use of a productive system analysis, is strengthening the concept of expansive and restrictive learning environments.  相似文献

The aim of this paper is to explore the distinctiveness of the professional doctorate in education (EdD). To deliver on this aim the paper contextualizes the local and particular EdD by locating it within its wider perspective. First the development of Higher Education (HE) in England is considered. Next the historical development of the EdD is examined. Finally the paper argues that the EdD is distinctive and challenges the university tradition. Moreover the paper begins to provide tentative suggestions to the way in which practitioners and researchers doing the EdD might act as knowledge workers, knowledge producers and work for change.  相似文献

This paper reports on one aspect of qualitative research on public understandings of food risks, focusing on lay understandings of genetically modified (GM) food in the UK context. A range of theoretical, conceptual, and empirical literature on food, risk, and the public understanding of science are reviewed. The fieldwork methods are outlined and empirical data from a range of lay groups are presented. Major themes include: varying "technical" knowledge of science, the relationship between knowledge and acceptance of genetic modification, the uncertainty of scientific knowledge, genetic modification as inappropriate scientific intervention in "nature", the acceptability of animal and human applications of genetic modification, the appropriate boundaries of scientific innovation, the necessity for GM foods, the uncertainty of risks in GM food, fatalism about avoiding risks, and trust in "experts" to manage potential risks in GM food. Key discussion points relating to a sociological understanding of public attitudes to GM food are raised and some policy implications are highlighted.  相似文献

This study provides an understanding of the current social media landscape for higher education institutions. While it is recognized that consistency in school branding across all communications with stakeholders is important to attract and retain students, relatively little work has been done to determine specifically what type of content should be included in a school’s social media campaign, nor has there been an investigation as to the relative frequency of the content. The authors use content analysis to examine Facebook posts from 66 top US colleges and universities and engagement from their constituents on these posts. Results show that there are significant differences in engagement received on posts across institution type. Additionally, media type and posting frequency are factors that contribute to engagement. This study provides direction on how university social media managers can better manage their social media content to improve engagement and increase the reach of their posts.  相似文献

This paper addresses the question of delegation of morality to a machine, through a consideration of whether or not non-humans can be considered to be moral. The aspect of morality under consideration here is protection of privacy. The topic is introduced through two cases where there was a failure in sharing and retaining personal data protected by UK data protection law, with tragic consequences. In some sense this can be regarded as a failure in the process of delegating morality to a computer database. In the UK, the issues that these cases raise have resulted in legislation designed to protect children which allows for the creation of a huge database for children. Paradoxically, we have the situation where we failed to use digital data in enforcing the law to protect children, yet we may now rely heavily on digital technologies to care for children. I draw on the work of Floridi, Sanders, Collins, Kusch, Latour and Akrich, a spectrum of work stretching from philosophy to sociology of technology and the “seamless web” or “actor–network” approach to studies of technology. Intentionality is considered, but not deemed necessary for meaningful moral behaviour. Floridi’s and Sanders’ concept of “distributed morality” accords with the network of agency characterized by actor–network approaches. The paper concludes that enfranchizing non-humans, in the shape of computer databases of personal data, as moral agents is not necessarily problematic but a balance of delegation of morality must be made between human and non-human actors.  相似文献

Belief revision can occur at multiple levels of abstraction, including lower-level and higher-order beliefs. It remains unclear, however, how conflicting evidence interacts with prior beliefs to encourage higher-order belief revision. This study explores how 4- and 5-year-olds (= 96) respond to evidence that directly conflicts with their causal higher-order beliefs. When shown a single event that directly violated a strongly supported prior belief, preschoolers largely maintained their initial higher-order belief. However, when the prior belief was more weakly supported and the counterevidence was stronger, children changed their minds. These findings indicate that young children can revise their higher-order beliefs and, furthermore, do so depending on the strength of both the evidence and their prior beliefs.  相似文献

Three experiments explored responses to molar and local schedule constraints. Thirsty rats pressed a lever for access to a water spout. In Experiment 1, response totals were unaffected by two local schedule characteristics—the variability of the instrumental requirement and the variability of the magnitude of contingent reward. Experiment 2 manipulated the correlation between the instrumental requirement and the magnitude of reward. This correlation did not affect the behavioral price ratio (presses per lick) at a molar level. At a local level, the positive correlation created a lower mean lick price than did the negative correlation. The rats licked more, and licked less efficiently, under the positive correlation than under the negative correlation. Experiment 3 compared two ways of manipulating the molar presses/lick ratio: The instrumental (contingent) series varied the instrumental (contingent) requirement, but held the other requirement constant. As the ratio increased, total leverpresses increased, and total licks decreased linearly; the two series did not differ significantly. At higher lick prices, the rats licked more efficiently and made more extra licks at the spout as it closed. The results help delimit the applicability of molar models of the organism’s response to schedule constraints.  相似文献

Use data from the Portuguese HBSC (Health Behaviour in School-Aged Children) survey, which was conducted by one of the authors who is the national representative of the European Study HBSC, a World Health Organisation collaborative study (Currie, Hurrelmann, Setterbulte, Smith, & Todd, 2000; Matos, Simões, Carvalhosa, Reis & Canha 2000), to examine correlates of depression and anxiety in a large, representative sample of adolescents. The study had four aims: (1) to examine the relationship between feelings of anxiety and depression; (2) to examine the association of positive peer relationships, and anxiety and depression in school-age adolescents; (3) to examine the relationship between health, peer relationships, depression and anxiety; and finally, (4) to assess age and gender differences with regard to the above issues. Measures were constructed of depression, anxiety, peer relationships, and health. Consistent with previous studies, anxiety and depression were found to be significantly correlated. A MANOVA revealed that females and adolescents in grades 8 and 10 were more likely to report high anxiety and/or depressive symptoms. High anxiety and depression in adolescence was associated with poor peer relationships and poorer health. Implications of these results and directions for further research are discussed.  相似文献

Emotional overeating (EOE) is the tendency to eat more in response to negative emotions; its etiology in early life is unknown. We established the relative genetic and environmental influences on EOE in toddlerhood and early childhood. Data were from Gemini, a population‐based cohort of 2,402 British twins born in 2007. EOE was measured using the “emotional overeating” scale of the Child Eating Behavior Questionnaire (CEBQ) at 16 months and 5 years. A longitudinal quantitative genetic model established that genetic influences on EOE were minimal; on the other hand, shared environmental influences explained most of the variance. EOE was moderately stable from 16 months to 5 years and continuing environmental factors shared by twin pairs at both ages explained the longitudinal association.  相似文献

EDUCATE is a London-based programme that supports the development of research-informed educational technology (EdTech), allowing entrepreneurs and start-ups to create their products and services, and simultaneously grow their companies in a more evidence-informed manner. The programme partners businesses with researchers who mentor, guide and support this research journey, a key aspect of which is the evaluation of the company’s EdTech product or service. However, conducting impact evaluations of technology in education is challenging, particularly for early stage technologies, as rapid cycles of innovation and change are part of their essence. Here, we present the pragmatic approach to evidence-informed education technology design and impact evaluation, as developed and adopted by the EDUCATE programme. The research process is shaped by the core principles of evidence-informed decision making detailed in the paper. The contributions of the paper are threefold. First, it defines and details an academia-industry-education collaboration model centred on a research training programme. Second, it presents emerging impact results of the programme. Third, it provides clear reflections on the challenges encountered during the implementation of the model in the EdTech ecosystem of London, which should be addressed if we are to move towards evidence-informed EdTech globally.  相似文献
