Knowledge about Aging and Alzheimer Disease: A Comparison of Professional Caregivers and Noncaregivers     

Tiana B. Rust  Sheree Kwong See 《Educational gerontology》2013,39(4):349-364

This study assessed professional caregivers of persons with Alzheimer disease (AD) and non-caregivers' knowledge about aging and AD. Participants completed modified versions of the Alzheimer Disease Knowledge Test and the multiple-choice version of the Facts on Aging Quiz #1. Overall, knowledge levels about AD and aging were low. Caregivers were found to be more knowledgeable about AD than were noncaregivers (58% and 42% correct, respectively), but these groups did not differ on knowledge about aging (40% and 39% correct, respectively). The most common misconceptions and areas of ignorance on the two tests demonstrate that participants rely on age stereotypes.  相似文献   

Horizons,not Boundaries,are the Language of Retirement: Sense of Fulfillment,Fears, and Life Trajectories of Faculty Extendees in the Philippines     

Allan B. de Guzman  Monica Lou S. Llantino  Viva Celina L. See  Ria Faye P. Villanueva  Yoomi Jung 《Educational gerontology》2013,39(9):749-762

This qualitative study probed into (a) the sense of fulfillment, (b) fears and anxieties, and (c) life trajectories of aged working professors recruited from one comprehensive university in the Philippines. Interestingly, findings of the study reveal that respondents were fulfilled and felt successful through the life outputs of their students; their self-worth was witnessed through continued employment and communication to students of ideas, work ethic, and values. Fears and anxieties were rarely felt because of religious commitments and prayers to God. Sense of delight was manifested through the satisfactory academic environment; the possession of supportive systems, including family, friends and community, and their plans of spending their remaining years with the family in leisure activities; and in joining religious organizations.  相似文献   

Preface to Special Topic: Papers from the 2009 Conference on Advances in Microfluidics and Nanofluidics, The Hong Kong University of Science & Technology, Hong Kong, 2009     

Leslie Y. Yeo 《Biomicrofluidics》2009,3(2)

The inaugural conference on Advances in Microfluidics and Nanofluidics was held at the Hong Kong University of Science and Technology on 5–7 January 2009 and brought together leading researchers from across a wide variety of disciplines from North America, Europe, Asia, and Oceania. This Special Topic section forms the second of the two issues dedicated to original contributions covering both fundamental physicochemical aspects of microfluidics and nanofluidics as well as their applications to the miniaturization of chemical and biological systems that were presented at the conference.In the last five years, we have observed rapid growth in the microfluidics and nanofluidics community in Asia, owing largely to the substantial strategic investments by both government and industry in the region to promote the microfabrication and nanotechnology sectors.¹ The organization of a regular meeting focusing on activities in the Asia-Pacific rim region was, therefore, timely, particularly to enhance dissemination of research of the highest quality within the region and to promote collaboration between researchers in the Asian community with their counterparts from Europe and the USA.Biomicrofluidics is, therefore, proud to be closely involved with the organization of the first of such conferences, Advances in Microfluidics and Nanofluidics 2009, which was kindly hosted by the Hong Kong University of Science and Technology (HKUST). As reported in the preface to the first of the two issues dedicated to invited reviews and original contributions associated with the conference,² the meeting, which took place over three days in the breathtaking HKUST campus overlooking Clearwater Bay in Hong Kong, was a tremendous success. Together with our colleagues, the Biomicrofluidics editors are busy putting in place arrangements for a follow-up meeting in January 2011. Given the overwhelming response and positive feedback we’ve had to date, we believe that Advances in Microfluidics and Nanofluidics will form a regular event in the calendar of the Asian microfluidics and nanofluidics community in the future.It was particularly pleasing to observe the translation of fundamental and theoretical work into advanced applied chip-based platforms for a variety of practical chemical and biological applications in the talks presented at the conference. The collection of articles in this second part, in fact, provides a gist of the flavor of the multidisciplinary research spanning the entire fundamental to applied research spectrum, which is exactly the scope which the journal intends to cover.Electrokinetics continues to be a dominant theme in this issue and within the microfluidics and nanofluidics community. The article by Ng et al.³ provides experimental evidence that might put to rest a longstanding area of debate within the electrokinetics community on the role of Faradaic charging in driving electro-osmotic flow, first proposed by Ben and Chang.⁴ In other electrokinetics papers, the role of interfaces is explored, for example, electrowetting on the superhydrophobic nanostructured surfaces of a lotus leaf⁵ and droplet manipulation in an immiscible dielectric liquid continuum under an electric field.⁶In addition, the characterization of the surface charge density of the nanopores etched in organic foils is reported by Xue et al.,⁷ which provides a deeper understanding of the mechanisms by which ions are transported in nanochannels, whereas Wei and Hsiao⁸ present a stochastic simulation to model the condensation of linear polyelectrolyte molecules under electric fields, in which they show the marked increase in the mobility of the polyelectrolyte chain during its unfolding in free-solution electrophoresis.Continuing along the theme of numerical simulations, particulate transport in converging-diverging microchannels was studied using a Lagrangian-Eulerian finite-element model,⁹ and slip arising in Couette flows over superhydrophobic surfaces was studied using a hybrid multiscale simulation that interfaces molecular dynamics simulations in the near-wall region with the continuum fluid model in the bulk.¹⁰ In other numerical studies, drop coalescence¹¹ and nanotube transport¹² were studied.Complementing these fundamental studies is the use of multiphase flows in microfluidic channels to engineer scaffolds for tissue engineering in which the bubbles trapped in liquid droplets transported in microchannels were employed to produced the pores of the scaffold.¹³ Other practical microfluidics applications, such as chip-based enhancement of DNA hybridization through a genetic-bead-based protocol¹⁴ and an automated ELISA chip for chemical-biological analysis with an enhancement in the detection range and time,¹⁵ also constitute papers in this Special Topic section.We hope you enjoy reading the papers in this Special Topic section and that it provides you with a feel for the broad multidisciplinary spectrum across fundamental and applied microfluidic and nanofluidic research that the conference, as well as the journal, intends to span. Do watch out for the conference announcement for the next Advances in Microfluidics and Nanofluidics meeting in 2011 on the Biomicrofluidics website (http://bmf.aip.org)—hope to see you there!  相似文献

Teachers’ use of research evidence in practice: a pilot study of feedback to enhance learning     

Beng Huat See  Stephen Gorard  Nadia Siddiqui 《Educational research; a review for teachers and all concerned with progress in education》2016,58(1):56-72

Background: There is worldwide interest in improving the effectiveness of teachers and teaching. This paper considers two strands of that interest. It revisits the impact of using enhanced feedback from teachers to pupils as a way of improving attainment, and it looks at the feasibility of teachers using research evidence to create their own interventions. Current evidence on the causal impact of effective feedback on learning is unclear: many studies have mixed results, are small in scale, lack randomisation or are not conducted in real classroom conditions. Purpose: The aim of this paper is to describe the experience of schools as they engage with research evidence to support their own enquiry into the effectiveness of feedback in the classroom. Research design: This study took place over one academic year, involving nine treatment schools in one local authority. The study involved teachers themselves using research findings to create an intervention, which took, as its focus, enhanced feedback in the classroom. Test results from these schools were compared to the results in 5 participating comparator schools, to the 49 other schools in the borough and to all state-funded primary schools in England. Results: Although teachers showed that they could engage with research evidence, the study indicated that the process was complex in practice. In addition, the independent impact evaluation suggested that enhanced feedback in itself does not necessarily lead to improved pupil test performance. Discussion and conclusions: The paper considers some of the challenges faced by teachers as they attempted to use research evidence, and discusses implications for schools wishing to use research evidence in practice. The findings of the study suggest that it may be feasible for practitioners to use research evidence to inform their own practice. However, to do it well would require clearer guidance, professional development and modelling of any strategies suggested. These findings have implications for policy on teacher development, and for the research community to make research outputs more comprehensible and accessible to research users.  相似文献

Evaluation of Students’ Understanding of Thermal Concepts in Everyday Contexts     

Hye-Eun Chu  David F. Treagust  Shelley Yeo  Marjan Zadnik 《International Journal of Science Education》2013,35(10):1509-1534

The aims of this study were to determine the underlying conceptual structure of the thermal concept evaluation (TCE) questionnaire, a pencil-and-paper instrument about everyday contexts of heat, temperature, and heat transfer, to investigate students’ conceptual understanding of thermal concepts in everyday contexts across several school years and to analyse the variables—school year, science subjects currently being studied, and science subjects previously studied in thermal energy—that influence students’ thermal conceptual understanding. The TCE, which was administered to 515 Korean students from years 10–12, was developed in Australia, using students’ alternative conceptions derived from the research literature. The conceptual structure comprised four groups—heat transfer and temperature changes, boiling, heat conductivity and equilibrium, and freezing and melting—using 19 of the 26 items in the original questionnaire. Depending on the year group, 25–55% of students experienced difficulties in applying scientific concepts in everyday contexts. Years of schooling, science subjects currently studied and physics topics previously studied correlated with development of students’ conceptual understanding, especially in topics relating to heat transfer, temperature scales, specific heat capacity, homeostasis, and thermodynamics. Although students did improve their conceptual understandings in later years of schooling, they still had difficulties in relating the scientific concepts to their experiences in everyday contexts. The study illustrates the utility of using a pencil-and-paper questionnaire to identify students’ understanding of thermal concepts in everyday situations and provides a baseline for Korean students’ achievement in terms of physics in everyday contexts, one of the objectives of the Korean national curriculum reforms.  相似文献   

Scientists’ Habits of Mind as Evidenced by the Interaction Between their Science Training and Religious Beliefs     

Richard K. Coll  Neil Taylor  Mark C. Lay 《International Journal of Science Education》2013,35(6):725-755

In Australia, education is the responsibility of each of the six states and two territories. Consequently there are significant differences between the science curricula offered by these eight educational authorities. This research analyses the educational significance of these curricular variations. A five‐level categorization of curriculum was used as the framework for the analysis. These five levels extend from the statement of the vision for the learning of science to the assessment of learning. The goal of the analysis was to determine the individual visions and whether they were consistently expressed in the syllabus documents published by the authorities. The study was restricted to physics, biology and chemistry in the senior school. The conclusion is that there is a richness of curriculum design within Australia and much can be learnt from the implicit curriculum experiment that is being undertaken with Australian school students.  相似文献   

‘Unconscious’ inclusion of students with learning disabilities in a Malaysian mainstream primary school: teachers' perspectives     

Lay Wah Lee  Hui Min Low 《Journal of Research in Special Educational Needs》2013,13(3):218-228

The inclusion of children with special needs in mainstream regular schools has been seen as the best practice in special education provision, most markedly since the 90s. International research has provided amassing evidence towards the advantages of inclusive model over a segregation model of special education provision. However, nearly two decades after the signing of the international pledge, namely the Salamanca Statement (UNESCO) towards accepting inclusive education, Malaysia has not yet fully gained the momentum to implement inclusive education for children with special needs, especially for children identified within the category of learning disabilities. Because of the delay in policy implementation, inclusive education remains sparingly practiced in some schools without formal support. This study aims to investigate a scenario of this practice in a mainstream primary school via interviewing the regular teachers. The ultimate aim of this investigation is to identify ways to move forward from the current practice of ‘unconscious inclusion’.  相似文献
