How Do Low-Income Chilean Parents Support Their Preschoolers’ Writing and Math Skills in a Grocery Game?     

Diana Leyva 《Early education and development》2019,30(1):114-130

This study examined how parents supported children’s writing and math and whether parents’ support predicted children’s academic skills from the beginning of pre-kindergarten to the end of kindergarten. Two hundred ten Chilean parents from low-income households were observed playing a grocery game with their preschoolers (M = 53 months). The grocery game (a game where dyads make a grocery list together and shop at a pretend store) could be used to foster writing and mathematics. Coders noted how often parents engaged in writing support, provided math support, and displayed directiveness (i.e., taking over the child’s activity). Children’s literacy and math skills were assessed at the beginning of pre-kindergarten and the end of kindergarten. Research Findings. Parents engaged in little writing support but displayed moderate levels of math support and high levels of directiveness in the grocery game. Parents’ math support uniquely predicted gains in children’s math skills, while parents’ directiveness negatively predicted gains in children’s literacy skills. Practice or Policy. Results from this study have the potential to inform parent-focused interventions. Findings highlight the need to provide parents with specific strategies to support their children’s literacy and math development and guidance about embedding these strategies into family routines.  相似文献   

Technological innovation in developing countries: a review of the literature     

Diana Crane 《Research Policy》1977,6(4):374-395

The recent literature on the role of science and technology in developing countries is reviewed in order to assess the extent of our current knowledge concerning the sociological factors affecting the development of indigenous scientific and technological innovations. Existing studies provide some preliminary evidence in favor of the hypothesis that inadequate linkages between institutions in the various sectors of developing societies inhibit the development and utilization of indigenous technological innovations.In general, relationships between government research organizations and the potential users of their technological innovations are absent or unsatisfactory. Academic research tends to be oriented toward the interests of the international scientific community. The substantial literature on the problems of indigenous technological transfer in India suggests that inadequate coordination between different sectors of that society is in part responsible for its failure to develop its potential for technological innovation.Recent attempts to stimulate the production and diffusion of indigenous technology in developing countries by creating new types of research institutes in the university and coordinating agencies in the government are discussed. Systematic evaluations of these programs are lacking, but coordinating agencies have often performed poorly because of insufficient power to influence the policies of other organizations.A sociological approach based on interorganizational analysis is suggested for future studies of this problem. This literature identifies the optimal characteristics of coordinating organizations at the government level and of research utilizations systems which link research organizations to their clients at the local level.A bibliography comprising 102 references classified by region is included.  相似文献   

Rapid bioparticle concentration and detection by combining a discharge driven vortex with surface enhanced Raman scattering     

Diana Hou  Siddharth Maheshwari    Hsueh-Chia Chang 《Biomicrofluidics》2007,1(1)

Rapid concentration and detection of bacteria in integrated chips and microfluidic devices is needed for the advancement of lab-on-a-chip devices because current detection methods require high concentrations of bacteria which render them impractical. We present a new chip-scale rapid bacteria concentration technique combined with surface-enhanced Raman scattering (SERS) to enhance the detection of low bacteria count samples. This concentration technique relies on convection by a long-range converging vortex to concentrate the bacteria into a packed mound of 200 μm in diameter within 15 min. Concentration of bioparticle samples as low as 10⁴ colony forming units (CFU)∕ml are presented using batch volumes as large as 150 μl. Mixtures of silver nanoparticles with Saccharomyces cerevisiae, Escherichia coli F-amp, and Bacillus subtilis produce distinct and noticeably different Raman spectra, illustrating that this technique can be used as a detection and identification tool.  相似文献   

Medical student attitudes to the autopsy and its utility in medical education: A brief qualitative study at one UK medical school          下载免费PDF全文

Attending postmortems enables students to learn anatomy and pathology within a clinical context, provides insights into effects of treatment and introduces the reality that patients die. Rates of clinical autopsies have declined and medical schools have cut obligatory autopsy sessions from their curricula making it difficult to assess medical student perceptions of, and attitudes towards, the educational value of autopsy. Our aim was to investigate these perceptions by designing a brief qualitative study comprising nominal technique and focus group discussions with Cambridge Graduate Course students, all of whom had attended autopsies. Three general themes emerged from the focus group discussions: the value of autopsy as a teaching tool and ways the experience could be improved, the initial impact of the mortuary and the autopsy itself, and the “emerging patient”—an emotional continuum running from cadaver to autopsy subject and living patient. Educational benefits of autopsy‐based teaching included greater understanding of anatomy and physiology, greater appreciation of the role of other health care professionals and an enhanced appreciation of psycho‐social aspects of medical practice. Students suggested improvements for ameliorating the difficult emotional consequences of attendance. We conclude that autopsy‐based teaching represents a low‐cost teaching technique which is highly valued by students and has application to many diverse medical specialties and skills. However, careful preparation and organization of sessions is required to maximize potential educational benefits and reduce any negative emotional impact.

Users as innovators in developing countries: The global sources of innovation and diffusion in mobile banking services     

Paul van der Boor  Pedro Oliveira  Francisco Veloso 《Research Policy》2014

This paper examines the extent to which users in developing countries innovate, the factors that enable these innovations and whether they are meaningful on a global stage. To study this issue, we conducted an empirical investigation into the origin and types of innovations in financial services offered via mobile phones, a global, multi-billion-dollar industry in which developing economies play an important role. We used the complete list of mobile financial services, as reported by the GSM Association, and collected detailed histories of the development of the services and their innovation process. Our analysis, the first of its kind, shows that 85% of the innovations in this field originated in developing countries. We also conclude that, at least 50% of all mobile financial services were pioneered by users, approximately 45% by producers, and the remaining were jointly developed by users and producers. The main factors contributing to these innovations to occur in developing countries are the high levels of need, the existence of flexible platforms, in combination with increased access to information and communication technology. Additionally, services developed by users diffused at more than double the rate of producer-innovations. Finally, we observe that three-quarters of the innovations that originated in non-OECD countries have already diffused to OECD countries, and that the (user) innovations are therefore globally meaningful. This study suggests that the traditional North-to-South diffusion framework fails to explain these new sources of innovation and may require re-examination.  相似文献   

Assessment of total body water and its compartments in elite judo athletes: comparison of bioelectrical impedance spectroscopy with dilution techniques     

Ezequiel M. Gonçalves  Catarina N. Matias  Diana A. Santos  Luis B. Sardinha  Analiza M. Silva 《Journal of sports sciences》2015,33(6):634-640

Bioelectrical impedance spectroscopy (BIS) is an inexpensive and non-invasive technique to measure total body water (TBW), extracellular water (ECW), and intracellular water (ICW). The purpose of this study was to validate TBW, ECW and ICW assessed by BIS, using dilution techniques as the reference method (REF) in elite judo athletes. Thirty-two Portuguese elite male judo athletes were evaluated during a period of weight stability. TBW, ECW and ICW were assessed by BIS (Xitron 4000). Deuterium and bromide dilution techniques were used as the criterion method for measuring TBW and ECW, while ICW was calculated as the difference between the two. BIS explained 96%, 77% and 94% of the total variability from REFs for TBW, ECW and ICW, respectively. BIS also demonstrated high precision (ρ ≥ 0.88) and accuracy (C_b = 0.98), with a minimum concordance coefficient correlation of 0.87 for ECW. The mean bias demonstrated that BIS slightly overestimated the REF in 1.1 kg (2.3%), 0.3 kg (1.6%) and 0.8 kg (2.7%) for TBW, ECW and ICW, respectively. The 95% limits of agreement ranged from ?1.2 to 3.3 kg in TBW, from ?1.8 to 2.4 kg in ECW and from ?1.0 to 2.6 kg in ICW. A non-significant trend was found between the difference and the mean of reference and alternative methods. These findings highlight the efficacy of BIS as a valid non-biased tool for the assessment of TBW and its compartments in elite male judo athletes, during a period of weight stability.  相似文献

Between the nation and the globe: education for global mindedness in Finland     

Vanessa de Oliveira Andreotti  Gert Biesta  Cash Ahenakew 《Globalisation, Societies & Education》2015,13(2):246-259

This article explores some of the tensions at the interface of nationalist and global orientations in ideals of global mindedness and global citizenship looking specifically at the Finnish context. We engage with discussions related to the social–political and historical context of national identity in Finland and outline the conceptual framework of an educational initiative related to the development of global mindedness through experiences of international mobility and partnerships. This conceptual outline presents a set of theoretical distinctions through which we seek to challenge humanist and universalist approaches to the question of (the formation of) global mindedness by arguing that the issue is neither about cognition or understanding nor about empathy and relationships but ultimately has to do with modes of existence and exposure. Similar to discussions in other small states, the historical trajectory in Finland illustrates how the encounter between the nation and the globe poses particular challenges for education as it runs the risk of reverting to ethnocentric rather than globally minded forms of national identity building. We argue that this risk cannot be addressed with the promotion of a mere understanding of or mere empathy for the other as an educational or political antidote but rather requires an existential approach.  相似文献
