The current explosion in mobile computing and telecommunications technologies holds the potential to transform "everyday" time and space, as well as changes to the rhythms of social institutions. Sociologists are only just beginning to explore what the notion of "mobility" might mean when mediated through computing and communications technologies, and so far, the sociological treatment has been largely theoretical. This article seeks instead to explore how a number of dimensions of time and space are being newly reconstructed through the use of mobile communications technologies in everyday life. The article draws on long-term ethnographic research entitled "The Socio-Technical Shaping of Mobile Multimedia Personal Communications," conducted at the University of Surrey. This research has involved ethnographic fieldwork conducted in a variety of locales and with a number of groups. This research is used here as a resource to explore how mobile communications technologies mediate time in relation to mobile spaces. First the paper offers a review and critique of some of the major sociological approaches to understanding time and space. This review entails a discussion of how social practices and institutions are maintained and/or transformed via mobile technologies. Ethnographic data is used to explore emerging mobile temporalities. Three interconnected domains in mobile time are proposed: rhythms of mobile use, rhythms of mobile use in everyday life, and rhythms of mobility and institutional change. The article argues that while these mobile temporalities are emerging, and offer new ways of acting in and perceiving time and space, the practical construction of mobile time in everyday life remains firmly connected to well-established time-based social practices, whether these be institutional (such as clock time, "work time") or subjective (such as "family time"). 相似文献

The purpose of this study was to examine the histopathologic reliability of embalmed cadaveric tissue taken from the gross anatomy laboratory. Tissue samples from hearts, livers, lungs, and kidneys were collected after the medical students’ dissection course was completed. All of the cadavers were embalmed in a formalin‐based fixative solution. The tissue was processed, embedded in paraffin, sectioned at six micrometers, and stained with H&E. The microscope slides were evaluated by a board certified pathologist to determine whether the cellular components of the tissues were preserved at a high enough quality to allow for histopathologic diagnosis. There was a statistically significant relationship between ratings and organ groups. Across all organs, there was a smaller proportion of “poor” ratings. The lung group had the highest percentage of “poor” ratings (23.1%). The heart group had the least “poor” ratings (0.0%). The largest percentage of “satisfactory” ratings were in the lung group (52.8%), and the heart group contained the highest percentage of “good” ratings (58.5%) The lung group had the lowest percentage of “good” ratings (24.2%). These results indicate that heart tissue is more reliable than lung, kidney, or liver tissue when utilizing tissue from the gross anatomy laboratory for research and/or educational purposes. This information advises educators and researchers about the quality and histopathologic reliability of tissue samples obtained from the gross anatomy laboratory.

Threshold concepts (TCs) are concepts that, when mastered, represent a transformed understanding of a discipline without which the learner cannot progress. We have undertaken a process involving more than 75 faculty members and 50 undergraduate students to identify a working list of TCs for biochemistry. The process of identifying TCs for biochemistry was modeled on extensive work related to TCs across a range of disciplines and included faculty workshops and student interviews. Using an iterative process, we prioritized five concepts on which to focus future development of instructional materials. Broadly defined, the concepts are steady state, biochemical pathway dynamics and regulation, the physical basis of interactions, thermodynamics of macromolecular structure formation, and free energy. The working list presented here is not intended to be exhaustive, but rather is meant to identify a subset of TCs for biochemistry for which instructional and assessment tools for undergraduate biochemistry will be developed. 相似文献

Many teachers are keen to implement sustainability education in primary schools but are lacking the confidence, skills and knowledge to do so. Teachers report that they do not understand the concept and cannot integrate sustainability into an already overcrowded curriculum. Identifying how teachers successfully integrate sustainability education into their teaching practice can offer important insights into how these perceived problems can be overcome. The paper is based on data from the third year of a longitudinal study about teacher education and teacher professional learning for sustainability in primary education. The third year of the study investigated teachers’ understandings of sustainability and how sustainability education is manifested in eight rural and regional primary schools in Victoria, Australia. Data included photographs of school grounds and sustainability projects, audio recordings of focus groups with teachers and principals, and field notes of meetings with school staff. Sustainability education was found to be an emergent practice necessarily constituted in the relation between teachers, students and community members and the materialities of local places. Partnerships were found to be an essential part of integrated sustainability programmes which extended into communities and places beyond the schools. The processes of learning involved pedagogies of creative problem-solving and inquiry learning that enabled children to lead the way. 相似文献

This article examines what has happened to training in public sector organisations in the UK in a period of austerity. It draws on individual-level data collected over the period 2000–2012 and establishment-level data collected from employer surveys carried out between 2005 and 2012. To understand these data further, 75 qualitative interviews with public sector employers were carried out between mid-2010 and early 2012. This article finds that while training incidence remained relatively high in the public sector, establishment-level control over planning and funding fell faster than in the private sector. Nevertheless, the public sector ethos of serving the community along with the tradition of the public sector as a ‘good employer’ meant that the training system within public sector organisations remained largely intact, even when the availability or frequency of some courses was reduced. The result was that limited training funds were made to go further by reducing the frequency of courses, prioritising courses immediately relevant to front-line services, tightening the application of eligibility criteria among potential trainees and economising on training delivery – summed up by one respondent as ‘training smarter’. 相似文献

To what extent and why do social origins matter for access to higher education, including access to elite universities? What is the role of private and selective schooling? This paper uses the 1970 British Cohort Study (BCS70) to analyse the trajectories of a generation currently in early middle age. We find that the influence of social origins, especially parental education, remains when both a wide range of cognitive measures and school attainment are controlled. Attending a private school is powerfully predictive of gaining a university degree, and especially a degree from an elite institution, while grammar schooling does not appear to confer any advantage. 相似文献

This study examined associations between maltreatment and early developmental vulnerabilities in a population sample of 68,459 children (Mage = 5.62 years, SD = .37) drawn from the Australian state of New South Wales, using linked administrative data for the children and their parents (collected 2001–2009). Associations were estimated between (a) any maltreatment, (b) the number of maltreatment types, and (c) the timing of first reported maltreatment and vulnerability and risk status on multiple developmental domains (i.e., physical, social, emotional, cognitive, and communication). Pervasive associations were revealed between maltreatment and all developmental domains; children exposed to two or more maltreatment types, and with first maltreatment reported after 3 years of age, showed greater likelihood of vulnerability on multiple domains, relative to nonmaltreated children. 相似文献
