Understanding academics’ resistance towards (online) student evaluation     

Bart Rienties 《Assessment & Evaluation in Higher Education》2014,39(8):987-1001

Many higher educational institutions and academic staff are still sceptical about the validity and reliability of student evaluation questionnaires, in particular when these evaluations are completed online. One month after a university-wide implementation from paper to online evaluation across 629 modules, (perceived) resistance and ambivalence amongst academic staff were unpacked. A mixed-method study was conducted amongst 104 academics using survey methods and follow-up semi-structured interviews. Despite a successful ‘technical’ transition (i.e. response rate of 60%, similar scores to previous evaluations), more than half of respondents reported a negative experience with this transition. The results indicate that the multidimensional nature of ambivalence towards change and the dual nature of student evaluations can influence the effectiveness of organisational transition processes.  相似文献

Russian Digital Collections in North America: A Survey     

Erika Spencer 《Slavic & East European Information Resources》2013,14(2-3):174-179

This article discusses an inventory of Russian digital collections that was gathered from publically available material on the Web in 2011. It touches on the opportunities and difficulties that come with the increase of digital material on the Web and how librarians can attempt to bring smaller collections to the attention of scholars and researchers.  相似文献

Managing open innovation projects with science-based and market-based partners     

Jingshu Du  Bart Leten  Wim Vanhaverbeke 《Research Policy》2014

This paper examines the relationship between (outside-in) open innovation and the financial performance of R&D projects, drawing on a unique dataset that contains information on the open innovation practices, management and performance of 489 R&D projects of a large European multinational firm. We introduce two types of open innovation partnerships – science-based and market-based partnerships – and examine their relationships with project financial performance. In addition, we investigate whether the open innovation—project performance relationships are influenced by the way how R&D projects are managed. Our results show that R&D projects with open innovation partnerships are associated with a better financial performance providing that they are managed in the most suitable way. Market-based partnerships are positively correlated with project performance if a formal project management process is used; however these partnerships are associated with a lower performance for loosely managed projects. In contrast, science-based partnerships are associated with higher project revenues for loosely managed projects only.  相似文献   

Science or graduates: How do firms benefit from the proximity of universities?     

Bart Leten  Paolo Landoni  Bart Van Looy 《Research Policy》2014

This paper examines the impact of universities on the technological performance of adjacent firms. We extend existing research by jointly analyzing, and comparing, the effects of education (graduates) and scientific research (publications) activities of universities on firms’ technological performance. Adopting the knowledge production framework, our study is conducted at the level of 101 Italian territorial areas (provinces) and four industries. Overall, fixed-effect panel data models reveal a positive effect of both university graduates and scientific publications on the technological performance of firms. At the same time, considerable industry differences are observed. While the provision of university graduates positively affects firm performance in all industries under study, additional effects for scientific research are only observed in electrical and pharmaceutical industries that are science-intensive and where the scientific knowledge base is changing rapidly over time. The observation that spillovers from academia into the industrial texture of provinces rely on education and research in an industry-specific manner is relevant to the design of appropriate research and innovation policies.  相似文献   

Simplified prototyping of perfusable polystyrene microfluidics     

Reginald Tran  Byungwook Ahn  David R. Myers  Yongzhi Qiu  Yumiko Sakurai  Robert Moot  Emma Mihevc  H. Trent Spencer  Christopher Doering  Wilbur A. Lam 《Biomicrofluidics》2014,8(4)

Cell culture in microfluidic systems has primarily been conducted in devices comprised of polydimethylsiloxane (PDMS) or other elastomers. As polystyrene (PS) is the most characterized and commonly used substrate material for cell culture, microfluidic cell culture would ideally be conducted in PS-based microsystems that also enable tight control of perfusion and hydrodynamic conditions, which are especially important for culture of vascular cell types. Here, we report a simple method to prototype perfusable PS microfluidics for endothelial cell culture under flow that can be fabricated using standard lithography and wet laboratory equipment to enable stable perfusion at shear stresses up to 300 dyn/cm² and pumping pressures up to 26 kPa for at least 100 h. This technique can also be extended to fabricate perfusable hybrid PS-PDMS microfluidics of which one application is for increased efficiency of viral transduction in non-adherent suspension cells by leveraging the high surface area to volume ratio of microfluidics and adhesion molecules that are optimized for PS substrates. These biologically compatible microfluidic devices can be made more accessible to biological-based laboratories through the outsourcing of lithography to various available microfluidic foundries.  相似文献   

Microfluidic impedance cytometry of tumour cells in blood     

Daniel Spencer  Veronica Hollis  Hywel Morgan 《Biomicrofluidics》2014,8(6)

The dielectric properties of tumour cells are known to differ from normal blood cells, and this difference can be exploited for label-free separation of cells. Conventional measurement techniques are slow and cannot identify rare circulating tumour cells (CTCs) in a realistic timeframe. We use high throughput single cell microfluidic impedance cytometry to measure the dielectric properties of the MCF7 tumour cell line (representative of CTCs), both as pure populations and mixed with whole blood. The data show that the MCF7 cells have a large membrane capacitance and size, enabling clear discrimination from all other leukocytes. Impedance analysis is used to follow changes in cell viability when cells are kept in suspension, a process which can be understood from modelling time-dependent changes in the dielectric properties (predominantly membrane conductivity) of the cells. Impedance cytometry is used to enumerate low numbers of MCF7 cells spiked into whole blood. Chemical lysis is commonly used to remove the abundant erythrocytes, and it is shown that this process does not alter the MCF7 cell count or change their dielectric properties. Combining impedance cytometry with magnetic bead based antibody enrichment enables MCF7 cells to be detected down to 100 MCF7 cells in 1 ml whole blood, a log 3.5 enrichment and a mean recovery of 92%. Microfluidic impedance cytometry could be easily integrated within complex cell separation systems for identification and enumeration of specific cell types, providing a fast in-line single cell characterisation method.  相似文献   

Understanding social learning relations of international students in a large classroom using social network analysis     

Bart Rienties  YingFei Héliot  Divya Jindal-Snape 《Higher Education》2013,66(4):489-504

A common assumption in higher education is that international students find it difficult to develop learning and friendship relations with host students. When students are placed in a student-centred environment, international students from different cultural backgrounds are “forced” to work together with other students, which allows students to learn from different perspectives. However, large lecture rooms may provide fewer opportunities for students to work together in small groups. The purpose of this article is to understand how 191 international students from 34 cultural backgrounds and 16 host students build learning and friendship relations in a large classroom of 207 students. We have used an innovative mixed-method design of social network analysis in a pre- and post-test manner combined with two sets of focus groups. Using multiple regression quadratic assignment procedures, the results indicate that learning ties after 11 weeks were significantly predicted by the friendship and learning ties established at the beginning of the module, (sub)specialisation, and whether students were Chinese or not. Contrary to previous findings, team divisions played only a marginal role in building (new) learning relations. A substantial segregation between Confucian Asian, European international and UK students was present. Follow-up qualitative data highlighted that international students made a conscious effort to build friendship and learning relations primarily outside the formal team, which for some were along co-national lines, while others were pro-actively looking for new perspectives from multi-national students. These results indicate that the instructional design might have a strong influence on how international and host students work and learn together. We believe that this study is the first to provide an in-depth and unique understanding of how international students from different cultural backgrounds build friendship and learning-relationships with other students in- and outside their classroom over time in a large classroom of 200+ students.  相似文献   

Reflections on the ‘site of struggle’: girls' experience of secondary education in the late 1950s     

Stephanie Spencer 《History of education》2013,42(4):437-449

Brian Simon’s Studies in the History of Education, 1780–1870, published in 1960, set out to counter nearly all work previously produced on the history of education in Britain in this period, and to direct the field towards a new course. It provided a Marxist perspective that drew upon Simon’s involvement in campaigns for educational reform over the previous decade. It also reflected the character of the Cold War in the academy in Britain at this time. Overall, it produced a form of people’s history that was shaped by politics and ideology and informed by Simon’s leading position in the British Communist Party. His work in this period marks him out as a highly significant Marxist historian, as well as one of the leading Marxist educators of his generation.  相似文献
