How do students’ accounts of sociology change over the course of their undergraduate degrees?     

Paul Ashwin  Andrea Abbas  Monica McLean 《Higher Education》2014,67(2):219-234

In this article we examine how students’ accounts of the discipline of sociology change over the course of their undergraduate degrees. Based on a phenomenographic analysis of 86 interviews with 32 sociology and criminology students over the course of their undergraduate degrees, we constituted five different ways of accounting for sociology. These ranged from describing sociology as a form of personal development focused on developing the students’ opinion to describing sociology as a partial way of studying the relations between people and society. The majority of students expressed more inclusive accounts of sociology over the course of their degrees. However, some students’ accounts suggested they had become disengaged with sociology. We argue that the differences in the ways that students were disengaged were not captured by our phenomenographic categories. In conclusion, we argue that our analysis illustrates the crucial role that students’ relations to knowledge play in understanding the transformative nature of higher education.  相似文献   

Drop-outs from Swiss Universities: an empirical analysis of data on all students between 1975 and 2008     

Stefan C. Wolter  Andrea Diem  Dolores Messer 《European Journal of Education》2014,49(4):471-483

This study presents in-depth empirical analyses of drop-outs from all Swiss universities for the entire student population between 1975 and 2008. The results show that most identifiable factors associated with a greater or lesser probability of dropping out are identical to those found in a recent Systematic Review (Larsen et al., 2013). The main findings are that: first, since the 1970s, there has been a marked trend towards falling drop-out rates which is largely due to female students who, today, have lower drop-out rates than their male counterparts; secondly, not only are there different drop-out rates for specific subjects of study, but there are also differences in baccalaureate profiles, which indicates that the skills acquired prior to entering university have a great impact on successful study; thirdly, students who change their first subject choice are at great risk of dropping out. No firm conclusions can yet be drawn about the Bologna reform but, based on the subjects which changed to the Bachelor/Master system between 2001 and 2003, no reduction in drop-out rates can be found as a result of the reform.  相似文献   

Authentically assessing graduate teaching: outside and beyond neo-liberal constructs     

Andrea C. Allard  Diane Mayer  Julianne Moss 《The Australian Educational Researcher》2014,41(4):425-443

In this paper, we challenge the current focus on ‘best practice’, graduate teacher tests, and student test scores as the panacea for ensuring teaching quality and argue for ways of thinking about evidence of quality beginning teaching outside and beyond the current neoliberal accountability discourses circulating in Australia and other countries. We suggest that teacher educators need to reinsert themselves as key players in the debates around quality beginning teaching, rather than being viewed as a source of the problem. To enable teacher educators to assume accountability for quality beginning teachers, we propose the framework of a capstone teacher performance assessment—a structured portfolio called the Authentic Teacher Assessment (ATA)—and examine examples of these assessments through the lens of critical discourse analysis. As a measure of ‘readiness to teach’, the ATA is compared with supervising teachers’ assessments of preservice teachers. We argue that structured portfolios that include artefacts derived from preservice teachers’ practice in classrooms along with graduate teacher self assessments provide a stronger accountability measure of effective beginning teaching and demonstrably address the current anxiety regarding ‘evidence’. We suggest that such an approach should be reliable enough to be ‘read’ by external assessors (and moderated across other teacher education institutions). Rigorous research on a national basis is called for in order to develop and implement a structured portfolio as rich evidence of graduates’ quality and readiness to teach.  相似文献   

Analysis of a load application point in spline coupling teeth     

Francesca CURà  Andrea MURA 《浙江大学学报(A卷英文版)》2014,15(4):302-308

The objective of this paper is to investigate the position of the resultant force in involute spline coupling teeth due to the contact pressure distribution for both ideal and misaligned conditions. In general, spline coupling teeth are in contact all along the involute profile and the load is far from uniform along the contact line. Theoretical models available in publications consider the resultant contact force as it is applied at the pitch diameter, and this study aims to evaluate the error introduced within the confines of a common approximation environment. This analysis is carried out through using finite element method （FEM） models, considering spline couplings in both ideal and misaligned conditions. Results show that the differences between the load application diameter and pitch diameter are not very obvious in both ideal and misaligned conditions; however, this ap- proximation becomes more important for the calculation of the tooth stiffness.  相似文献   

Engaging Faculty for Innovative STEM Bridge Programs     

Andrea C. Goldfien  Norena Norton Badway 《Community College Journal of Research & Practice》2014,38(2-3):122-130

Bridge programs, in which underprepared students gain the academic and technical skills necessary for college level courses and entry-level employment, are a promising initiative for expanding access to, and success in, community college education. For career pathways related to science, technology, engineering, or mathematics (STEM), bridge programs are critical for enlarging the pool of students who are exposed to, and can aspire to, STEM preparation. This study, conducted with support from the National Science Foundation Advanced Technological Education program, followed four community colleges for a year to understand local factors that facilitated or impeded implementation of a bridge program in which basic skills were contextualized in biotechnology. The findings are that implementation of a contextualized curriculum requires substantial faculty learning. Implementation of these bridge programs was facilitated by instructional leadership by both administration and faculty. Administration assisted in creating the conditions that supported learning by coordinating faculty schedules and funding faculty time for initial and ongoing program development. Faculty benefitted by the support of experienced team members who could guide interdisciplinary learning. Implementation was facilitated when team members met frequently and when faculty worked collaboratively to implement the curriculum. Recommendations include planning for faculty development, both for faculty collaboration and contextualizing curriculum.  相似文献   

Open service innovation and the firm's search for external knowledge     

Andrea Mina  Elif Bascavusoglu-Moreau  Alan Hughes 《Research Policy》2014

The concept of open innovation captures the increasing propensity of firms to work across their traditional boundaries of operation. This phenomenon has largely been studied from the viewpoint of manufacturing businesses while services have received much less attention despite the predominant role they play in advanced economies. This paper focuses on open innovation in services, both as a subsector of the economy and as a component of the activities of manufacturing firms. We study the open innovation practices of business services firms and then consider the implications for open innovation of the adoption of a service inclusive business model by manufacturing firms. Our analyses are based on a unique dataset with information on open innovation activities amongst UK firms. Overall, engagement in open innovation increases with firm size and R&D expenditure. Business services are more active open innovators than manufacturers; they are more engaged in informal relative to formal open innovation practices than manufacturers; and they attach more importance to scientific and technical knowledge than to market knowledge compared to manufacturing firms. Open innovation practices are also associated with the adoption of a service inclusive business model in manufacturing firms and service-integrated manufacturers engage in more informal knowledge-exchange activities. The paper contributes towards a reconceptualisation of open innovation in service businesses and a deeper evidence-based understanding of the service economy.  相似文献   

Unusually difficult clinical presentation of an infant suffering from congenital cytomegalovirus (CMV) infection combined with alpha 1-antitrypsin (A1AT) deficiency     

Ines Poto?njak  Goran Te?ovi?  Andrea Te?ija Kuna  Mario ?tefanovi?  Orjena ?aja 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2014,24(3):396-402

Congenital Cytomegalovirus (CMV) infection and alpha 1-antitrypsin (A1AT) deficiency are separately well described entities, but their simultaneous occurrence can pose a special challenge to a clinician, especially dealing with optimal diagnostic as well as therapeutic approach. Congenital CMV infection is the most common vertically transmitted infection in developed countries. In 85–95% of newborns it runs asymptomatic, while in others it is presented with jaundice, petechias, hepatosplenomegaly and central nervous system damage. A1AT deficiency is on the other hand, the most common genetic liver disease in children, and the clinical spectrum varies from the accidentally detected increased levels of transaminases through to the severe infant cholestasis that can progress to cirrhosis. The following case report describes a two-month old male with severe clinical presentation of congenital CMV infection probably exacerbated due to A1AT deficiency comorbidity. The clinical manifestations and unusually difficult clinical signs this infant presented lead to assumption that the additional liver damage exists. Extensive laboratory analyses were performed, including PCR for CMV DNA, A1AT serum concentration, A1AT genotyping, followed and confirmed with phenotyping. Patient was treated parenteral with ganciclovir, what continued with oral valganciclovir and supportive therapy. Intensive and thorough supportive treatment of the infant resulted in satisfactory progress and excellent outcome. Patient was followed-up till the age of 18 months. The presented case provides excellent example about successful overcoming obstacles in differential diagnosis of A1AT in neonates and infants. Medical charts analysis was the methodology used in making this report.  相似文献   

Acceptance,motivations, and usage of social media as a marketing communications tool amongst employees of sport national governing bodies     

Andrea N. Eagleman 《Sport Management Review》2013,16(4):488-497

National governing bodies (NGB) of sport are not-for-profit organisations that typically receive less mainstream media coverage and have much smaller marketing budgets than mainstream professional sports. Therefore, they must seek alternative methods from mainstream media and traditional marketing in order to increase brand awareness and reach fans and stakeholders. While all sport organisations stand poised to benefit from social media, NGBs seem to be a segment of the sport industry uniquely positioned to capitalise on social media's benefits. Because there is currently no known literature on NGBs’ use of social media, this study examined the role that social media plays within NGBs in the United States including employees’ acceptance of social media, motivations to use social media, and the organisation's current usage of social media. An online survey was distributed to NGB employees in the spring of 2012, and results revealed that contrary to studies on other sport organisations, NGB employees reported high levels of acceptance and motivation to use social media regardless of demographic factors. Additionally, NGBs seemed to use social media as a communications tool to a greater degree than as a marketing tool. Implications for international and niche sport organisations are presented in the conclusion.  相似文献

Exercise training and impaired glucose tolerance in obese humans     

Andrea Margaret McNeilly  Marie Murphy  Jane McEneny  Tom Trinick  George Burke 《Journal of sports sciences》2013,31(8):725-732

Abstract

Individuals with impaired glucose tolerance (IGT) are at greater risk of developing diabetes than in normoglycaemia. The aim of this study was to examine the effects of 12-weeks exercise training in obese humans with IGT. Eleven participants (6 males and 5 females; 49±9 years; mean Body Mass Index (BMI) 32.4 kg · m^?2), completed a 12-week brisk walking intervention (30 min per day, five days a week (d · wk^?1), at 65% of age-predicted maximal heart rate (HR_max). Anthropometric measurements, dietary intake, pulse wave velocity (PWV, to determine arterial stiffness) and blood pressure (BP) were examined at baseline and post intervention. Fasting blood glucose, glycosylated haemoglobin, insulin, blood lipids, indices of oxidative stress and inflammation (lipid hydroperoxides; superoxide dismutase; multimeric adiponectin concentration and high-sensitivity C-reactive protein) were also determined. Post intervention, PWV (9.08±1.27 m · s^?1 vs. 8.39±1.21 m · s^?1), systolic BP (145.4±14.5 vs. 135.8±14.9 mmHg), triglycerides (1.52±0.53 mmol ^. L^?1 vs. 1.31±0.54 mmol ^. L^?1), lipid hydroperoxides (1.20±0.47 μM · L^?1 vs. 0.79±0.32 μM · L^?1) and anthropometric measures decreased significantly (P < 0.05). Moderate intensity exercise training improves upper limb vascular function in obese humans with IGT, possibly by improving triglyceride metabolism, which may subsequently reduce oxidative stress. These changes were independent of multimeric adiponectin modification and alterations in other blood biomarkers.  相似文献
