Governance of Universities and Scientific Innovation

In this chapter the tension between the tendency of scientific disciplines to "diversify" and the capacities of universities to give new scientific fields an institutional "home" is tackled. The assumption is that new scientific fields must find support among scientists and cognitive units of universities in order to be included. As science is a strongly competitive social field, inclusion often meets resistance. It is argued in this chapter that opportunities for new scientific fields to be included depend on the kind of governance regimes ruling universities. A comparison of the former bureaucratic-oligarchic governance model in most European universities with the existing new public management governance model demonstrates that the propensity of universities to include new scientific fields has increased though there might be a price to pay in terms of which fields stand a chance of being integrated and in terms of institutional possibilities for the invention of new ideas.

Cooperation and game theory, free software or the #15m movement: Two examples for universities

Closing talk of the Open Access Week 2011 at the UOC, by Josep Jover. Why do altruistic strategies beat selfish ones in the spheres of both free software and the #15m movement? The #15m movement, like software but unlike tangible goods, cannot be owned. It can be used (by joining it) by an indeterminate number of people without depriving anyone else of the chance to do the same. And that turns everything on its head: how universities manage information and what their mission is in this new society. In the immediate future, universities will be valued not for the information they harbour, which will always be richer and more extensive beyond their walls, but rather for their capacity to create critical masses, whether of knowledge research, skill-building, or networks of peers... universities must implement the new model or risk becoming obsolete.

Beyond the Net Generation debate: A comparison between digital learners in face-to-face and virtual universities

This paper is based on the hypothesis that the use of technology to support learning is not related to whether a student belongs to the Net Generation, but that it is mainly influenced by the teaching model. The study compares behaviour and preferences towards ICT use in two groups of university students: face-to-face students and online students. A questionnaire was applied to asample of students from five universities with different characteristics (one offers online education and four offer face-to-face education with LMS teaching support).

A systems view of risk factors for knee osteoarthritis reveals insights into the pathogenesis of the disease.

Early detection of osteoarthritis (OA) remains a critical yet unsolved multifaceted problem. To address the multifaceted nature of OA a systems model was developed to consolidate a number of observations on the biological, mechanical and structural components of OA and identify features common to the primary risk factors for OA (aging, obesity and joint trauma) that are present prior to the development of clinical OA. This analysis supports a unified view of the pathogenesis of OA such that the risk for developing OA emerges when one of the components of the disease (e.g., mechanical) becomes abnormal, and it is the interaction with the other components (e.g., biological and/or structural) that influences the ultimate convergence to cartilage breakdown and progression to clinical OA. The model, applied in a stimulus-response format, demonstrated that a mechanical stimulus at baseline can enhance the sensitivity of a biomarker to predict cartilage thinning in a 5 year follow-up in patients with knee OA. The systems approach provides new insight into the pathogenesis of the disease and offers the basis for developing multidisciplinary studies to address early detection and treatment at a stage in the disease where disease modification has the greatest potential for a successful outcome.

Beyond the net generation debate: A comparison of digital learners in face-to-face and virtual universities

In the last decade, an important debate has arisen about the characteristics of today"s students due to their intensive experience as users of ICT. The main belief is that frequent use of technologies in everyday life implies that competent users are able to transfer their digital skills to learning activities. However, empirical studies developed in different countries reveal similar results suggesting that the"digital native" label does not provide evidence of a better use of technology to support learning. The debate has to go beyond the characteristics of the new generation and focus on the implications of being a learner in a digitalised world. This paper is based on the hypothesis that the use of technology to support learning is not related to whether a student belongs to the Net Generation, but that it is mainly influenced by the teaching model. The study compares behaviour and preferences towards ICT use in two groups of university students: face-to-face students and online students. A questionnaire was applied to a sample of students from five universities with different characteristics (one offers online education and four offer face-to-face education with LMS teaching support). Findings suggest that although access to and use of ICT is widespread, the influence of teaching methodology is very decisive. For academic purposes, students seem to respond to the requirements of their courses, programmes, and universities. There is a clear relationship between students" perception of usefulness regarding certain ICT resources and their teachers" suggested uses of technologies. The most highly rated technologies correspond with those proposed by teachers. The study shows that the educational model (face-to-face or online) has a stronger influence on students" perception of usefulness regarding ICT support for learning than the fact of being a digital native.

Role of basic calcium phosphate crystals in osteoarthritis

L'arthrose est une maladie dégénérative des articulations due à une dégradation progressive du cartilage. La calcification de l'articulation (essentiellement due à des dépôts de cristaux de phosphate de calcium basique -cristaux BCP-) est une caractéristique de cette maladie. Cependant, le rôle des cristaux BCP reste à déterminer. Nous avons tout d'abord déterminé en utilisant des cultures primaires de chondrocytes que les cristaux de BCP induisaient la production de la cytokine IL-6, via une signalisation intracellulaire implicant les kinase Syk, PI3 et Jak et Stat3. Les cristaux de BCP induisent également la perte de protéoglycanes et l'expression de IL-6 dans des explants de cartlage humain et ces deux effets peuvent être bloqués par un inhibiteur de IL-6, le Tocilizumab. Par ailleurs, nous avons trouvé que l'IL-6 ajouté à des chondrocytes, favorisait la formation de cristax de BCP et augmentait l'expression de gènes impliqués dans le processus de minéralisation : Ank (codant pour un transporteur de pyrophooshate), Annexin5 (codant pour un canal calcique) et Pit-1 (codant pour un transporteur de phoshate). In vivo, les cristaux de BCP injectés dans l'articulation de souris induisent une érosion du cartilage. Dans un modèle murin d'arthrose du genou induit par ménisectomie, nous avons observé la formation progressive de cristaux de BCP. Fait intéressant, la présence de ces cristaux dans l'articulation précédait la destruction du cartilage. Un agent susceptible de bloquer les calcifications tel que le sodium thiosulfate (STS), administré à des souris ménisectomisées, inhibait le dépôt intra-articulaire de ces cristaux ainsi que l'érosion du cartilage. Nous avons identifié ainsi un cercle vicieux dans l'arthrose, les cristaux induisant l'interleukine-6 et l'interleukine-6 induisant la formation de ces cristaux. Nous avons étudié si on pouvait bloquer cette boucle cristaux de BCP-IL6 soit par des agents décalcifiants, soit par des inhibiteurs d'IL-6. In vitro, des anticorps anti IL- 6 ou des inhibiteurs de signalisation, inhibaient significativement IL-6 et la minéralisation induite par IL-6. De même le STS inhibait la formation de ces cristaux et la production de l'IL-6. Tout récemment, nous avons trouvé que des inhibiteurs de la xanthine oxidoréductase étaient aussi capables d'inhiber à la fois la production d'IL-6 et la minéralization des chondrocytes. Finalement, nous avons pu exclure un rôle du système IL-1 dans le modèle d'arthrose induite par ménisectomie, les souris déficientes pour IL-1a/ß, MyD88 et l'inflammasome NLRP3 n'étant pas protégées dans ce modèle d'arthrose. L'ensemble de nos résultats montre que les cristaux BCP sont pathogéniques dans l'arthrose et qu'un inhibiteur de minéralisation tel que le STS ou un inhibiteur de l'interleukine-6 constitueraient des nouvelles thérapies pour l'arthrose. -- Osteoarthritis (OA), the most common degenerative disorder of the joints, results from an imbalance between the breakdown and repair of the cartilage and surrounding articular structures. Joint calcification (essentially due to basic calcium phosphate (BCP) crystal deposition) is a characteristic feature of OA. However, the role of BCP crystal deposition in the pathogenesis of OA remains unclear[1][1]. We first demonstrated that in primary murine chondrocytes exogenous BCP crystals led to IL-6 up-modulation and that BCP crystal signaling pathways involved Syk and PI3 kinases, and also gp130 associated molecules, Jak2 and Stat3. BCP crystals also induced proteoglycan loss and IL-6 expression in human cartilage expiants, (which were significantly reduced by an IL-6 inhibitor). In addition, we found that in chondrocytes exogenous IL-6 promoted calcium-containing crystal formation and up- regulation of genes codifying for proteins involved in the calcification process: the inorganic pyrophosphate transport channel Ank, the calcium channel Annexinö and the sodium/phosphate cotransporter Piti. In vivo, BCP crystals injected into murine knee joints induced cartilage erosion. In the menisectomy model, increasing deposits, identified as BCP crystals, were progressively observed around the joint before cartilage erosion. These deposits strongly correlated with cartilage degradation and IL-6 expression. These results demonstrated that BCP crystals deposition and IL-6 production are mutually reinforcing in the osteoarthritic pathogenic process. We then investigated if we could block the BCP-IL6 loop by either targeting IL-6 production or BCP crystal deposits. Treatment of chondrocytes with anti-IL-6 antibodies or inhibitors of IL-6- signaling pathway significantly inhibited IL-6-induced crystal formation. Similarly, sodium thiosulfate (STS), a well-known systemic calcification inhibitor, decreased crystal deposition as well as HA-induced IL-6 secretion in chondrocytes and, in vivo, it decreased crystal deposits size and cartilage erosion in menisectomized knees. Interestingly, we also found that xanthine-oxidoreductase (XO) inhibitors inhibited both IL-6 production and calcium crystal depositis in chondrocytes. We began to unravel the mechanisms involved in this coordinate modulation of IL-6 and mineralization. STS inhibited Reactive Oxygen Species (ROS) generation and we are currently investigating whether XO represents a major source of ROS in chondrocyte mineralization. Finally, we ruled out that IL-1 activation/signaling plays a role in the murine model of OA induced by menisectomy, as IL-1a/ß, the IL-1 R associated molecule MyD88 and NLRP3 inflammasome deficient mice were not protected in this model of OA. Moreover TLR-1, -2, -4,-6 deficient mice had a phenotype similar to that of wild-type mice. Altogether our results demonstrated a self-amplification loop between BCP crystals deposition and IL-6 production, which represents an aggravating process in OA pathogenesis. As currently prescribed OA drugs are addressing OA symptoms,our results highlight a potential novel treatment strategy whereby inhibitors of calcium- containing crystal formation and IL-6 could be combined to form the basis of a disease modifying treatment and alter the course of OA.

Evolution of Ba and Role of Absorptive Capacity in Collaboration between MNCs and Chinese Universities in China

During the recent years, collaboration with Chinese universities has aroused growing interest among multinational companies (MNCs). Cross-cultural university-industry (U-I) collaboration creates various challenges in collaborative knowledge creation and innovation due to the differences e.g. between university and company motivation, objectives and activities. Also different values, norms, and means of actions result often in collisions and misunderstandings. This thesis examines the establishment of the relationships and the evolution of the collaboration between MNCs and Chinese universities. Empirical findings underscore that the partners in collaboration are required to possess research interest as well as capability to acquire, assimilate and exploit new external knowledge. Time and communication have a critical role in the evolution of the collaboration. In China the personal relationships, guanxi, play an important role. Collaborative knowledge creation requires a platform, Ba, which enables the creation of common understanding, commitment, trust and mutual respect. Empirical data has been collected through interviewing company experts and academe of Chinese universities from ICT and forest industries as well as attending panel discussions and meetings with the experts from the field of study.

New insight in the relationship between regional patterns of knee cartilage thickness, osteoarthritis disease severity, and gait mechanics.

To test if the relationship between knee kinetics during walking and regional patterns of cartilage thickness is influenced by disease severity we tested the following hypotheses in a cross-sectional study of medial compartment osteoarthritis (OA) subjects: (1) the peak knee flexion (KFM) and adduction moments (KAM) during walking are associated with regional cartilage thickness and medial-to-lateral cartilage thickness ratios, and (2) the associations between knee moments and cartilage thickness data are dependent on disease severity. Seventy individuals with medial compartment knee OA were studied. Gait analysis was used to determine the knee moments and cartilage thickness was measured from magnetic resonance imaging. Multiple linear regression analyses tested for associations between cartilage thickness and knee kinetics. Medial cartilage thickness and medial-to-lateral cartilage thickness ratios were lower in subjects with greater KAM for specific regions of the femoral condyle and tibial plateau with no associations for KFM in patients of all disease severities. When separated by severity, the association between KAM and cartilage thickness was found only in patients with more severe OA, and KFM was significantly associated with cartilage thickness only for the less severe OA subjects for specific tibial plateau regions. The results support the idea that the KAM is larger in patients with more severe disease and the KFM has greater influence early in the disease process, which may lessen as pain increases with disease severity. Each component influences different regions of cartilage. Thus the relative contributions of both KAM and KFM should be considered when evaluating gait mechanics and the influence of any intervention for knee OA.

Labor Mobility of the Chinese Graduates from British and Spanish Universities: What Happens to the "Talent Migration"?

The scholarship on migration in Europe heavily focuses on the integration of economically vulnerable migrants. In the age of commercialization of education, however, the European Union attracts a rising number of highly skilled non-EU migrants that take up studies across the continent. Despite economic downturn, the EU universities experience a rapid growth in the number of Chinese students, many of whom settle in Europe upon graduation. Surprisingly, although the number of Chinese students in the EU increases, scholars largely ignore the labor paths that these highly skilled migrants take upon graduating from European universities. This study aims to fill this gap by exploring the variation in the Chinese graduates’ labor incorporation patterns and in their spatial mobility. In this project, I also examine macro-level hypotheses predicting that the EU and host states’ labor market institutions, changes in the EU policies on the highly skilled and the outburst of economic crisis matter for the Chinese highly skilled social and spatial mobility. Seizing on surveys, interviews and on the bodies of literature on stratification and social mobility, economic incorporation, social capital and human capital, I look at the Chinese students that graduated from universities in Great Britain and Spain. These states differ in the university tuition fees, migration policies towards the highly skilled workers and in the period of the Chinese students’ influx, thus providing an economically and socially diverse sample. My research will contribute to the literature on the relations between migrants’ social mobility, class and status background and spatial mobility, at the same time adding a transnational level perspective to the study of highly skilled Asian migration.

Interdependency management in universities: a case study

There remains uncertainty in scientific discussions regarding the governance of universities in new public management regimes in terms of who actually 'rules' in the university. Apparently, a strengthened management leadership is confronted with continuing elements of academic self-regulation and professional autonomy in knowledge production and diffusion. Organisational and academic rationales coexist in today's management of universities. This article endeavours to clarify some of the ambiguities pertaining to the coexistence of two authorities by demonstrating the working of 'interdependency management' that is taking place within universities. For this purpose, the authors have scrutinised research, teaching and recruitment policies in one Swiss university that is subject to such ambiguities. The study confirms existing research in that a command-and-control system is not applied. Policymaking in universities is instead based on a mix of negotiations in faculties that are taking place in the 'shadow of hierarchy', negotiated bargaining between faculties and leaders and occasional unilateral decisions of leaders. This mitigates latent conflicts between management and the academic community: strategic orientations of the university are generally accepted by the academic community while the academic community has influence on policy formulation and maintains defining powers over policy substance.

Graduating 4th year radiology residents' perception of optimal imaging modalities for neoplasm and trauma: a pilot study from four U.S. universities

OBJECTIVE: Our purpose was to assess 4th year radiology residents' perception of the optimal imaging modality to investigate neoplasm and trauma. MATERIALS AND METHODS: Twenty-seven 4th year radiology residents from four residency programs were surveyed. They were asked about the best imaging modality to evaluate the brain and spine, lungs, abdomen, and the musculoskeletal system. Imaging modalities available were MRI, CT, ultrasound, PET, and X-ray. All findings were compared to the ACR appropriateness criteria. RESULTS: MRI was chosen as the best imaging modality to evaluate brain, spine, abdominal, and musculoskeletal neoplasm in 96.3%, 100%, 70.4%, and 63% of residents, respectively. CT was chosen by 88.9% to evaluate neoplasm of the lung. Optimal imaging modality to evaluate trauma was CT for brain injuries (100%), spine (92.6%), lung (96.3%), abdomen (92.6%), and major musculoskeletal trauma (74.1%); MRI was chosen for sports injury (96.3%). There was agreement with ACR appropriateness criteria. CONCLUSION: Residents' perception of the best imaging modalities for neoplasm and trauma concurred with the appropriateness criteria by the ACR.
