Low key but not low impact: the results of the EU's 'transition' summit. EPC Post-Summit Analysis, 27 October 2014

The European Council Summit of 23-24 October 2014 may have been relatively low key, but many important decisions were made which could encourage historical changes. In this post-summit analysis, Janis A. Emmanouilidis examines the agreement reached on a new climate and energy policy framework for 2020-2030 which despite falling short of the European Commission’s original proposals, it nevertheless delivers a positive message to international community ahead of the global climate negotiations next year. He also highlights the significance of the request from euro-zone leaders for a new report on ‘better economic governance’ by December. More broadly, he uses this moment of transition in the EU’s leadership to analyse the current state and future direction of the Union, and underlines the need to provide a coherent and holistic response to the damage caused by the crisis and the challenges facing the Union, on the basis of an ambitious but pragmatic ‘package deal’ – a new pact between EU governments, and between the Union and its citizens – to heal the divisions of recent years and restore public faith in the benefits of EU membership.

The EU internal market - a stake or a tool in European-Russian gas relations. OSW Commentary No. 54, 2011-06-24

Since 2010 we have observed a new quality in EU energy policy. It is related to the European Commission’s more or less direct engagement in the bilateral gas relations of a part of the new member states – Poland, Bulgaria and Lithuania – with Russia. Although the long term outcome of this activity of the EC is as yet unclear it seems to be important for several reasons. Firstly it might increase the possibilities of the enforcement of the EU’s directives liberalising the internal gas market and specifically their implementation in individual gas agreements with suppliers from third countries (Gazprom). The consistency and determination of the EC in this field may be decisive for the future direction and depth of the liberalisation of the EU gas market. Furthermore, present developments may lead to an increase in EU and specifically EC competence in the field of energy policy, especially its external dimension. So what lessons can we draw from recent Commission activities on the following issues: – Implementing EU gas market 2nd and 3rd liberalisation packages and their main provisions – EU energy policy and its external dimension – recent developments and the EU’s role – EU-Russia gas relations – where Russian and EU interests diverge.

Long distance dispersion managed soliton transmission experiments

This thesis presents results of transmission experiments using optical solitons in a dispersion managed optical fibre recirculating loop. The basic concepts of pulse propagation in optical fibre are introduced before optical solitons and their use in optically amplified fibre systems are discussed. The role of dispersion management in such systems is then considered. The design, operation and limitations of the recirculating loop and soliton sources which were used and the experimental techniques are described before the experimental work is presented. The experimental work covers a number of areas all of which used dispersion management of the transmission line. A novel ultra-long distance propagation scheme which achieved low timing jitter by suppression of the amplifier noise and by working close to the zero dispersion wavelength has been discovered. The use of fibre Bragg gratings as wavelength filters to suppress noise and reduce timing jitter has been investigated. The performance of the fibre grating cornpared favourably with that of a bulk device and was in good agreement with theoretical predictions. The upgrade of existing standard fibre systems to higher bit rates is currently an important issue. The possibility of using solitons with dispersion compensation to allow an increase in data rate of existing standard fibre systems to 10Gbit/s over 5000km has been demonstrated. The applicability of this technique to longer distances, higher bit rates or longer amplifier spans is also investigated by optimisation of the dispersion management scheme. The use of fibre Bragg gratings as the dispersion compensating elements in such standard fibre transmission experiments has been examined and the main problem that these devices currently have, high polarisation mode dispersion, is discussed. The likely future direction of optical communications and what part solitons and dispersion management will play in this development is discussed in the thesis conclusions

Developing Innovative TEL Practice in Teacher Education

This interactive symposium will focus on the use of different technologies in developing innovative practice in teacher education at one university in England. Technology Enhanced Learning (TEL) is a field of educational policy and practice that has the power to ignite diametrically opposing views and reactions amongst teachers and teacher educators, ranging across a spectrum from immense enthusiasm to untold terror. In a field where the skills and experience of individuals vary from those of digital natives (Prensky 2001) to lags and lurkers in digital spaces, the challenges of harnessing the potential of TEL are complex. The challenges include developing the IT skills of trainees and educators and the creative application of these skills to pedagogy in all areas of the curriculum. The symposium draws on examples from primary, secondary and post-compulsory teacher education to discuss issues and approaches to developing research capacity and innovative practice using different etools, many of which are freely available. The first paper offers theoretical and policy perspectives on finding spaces in busy professional lives to engage in research and develop research-informed practice. It draws on notions of teachers as researchers, practitioner research and evidenc-ebased practice to argue that engagement in research is integral to teacher education and an empowering source of creative professional learning for teachers and teacher educators. Whilst acknowledging the challenges of this stance, examples from our own research practice illustrate how e-tools can assist us in building the capacity and confidence of staff and students in researching and enhancing teaching, learning and assessment practice. The second paper discusses IT skills development through the TEL pathway for trainee teachers in secondary education across different curriculum subjects. The lead tutor for the TEL pathway will use examples of activities developed with trainee teachers and university subject tutors to enhance their skills in using e-tools, such as QR codes, Kahoot, Padlet, Pinterest and cloud based learning. The paper will also focus on how these skills and tools can be used for action Discussant - the wider use of technologies in a university centre for teacher education; course management, recruitment and mentor training. research, evaluation and feedback and for marking and administrative tasks. The discussion will finish with thoughts on widening trainee teachers’ horizons into the future direction of educational technology. The third paper considers institutional policies and strategies for promoting and embedding TEL, including an initiative called ‘The Learning Conversation’, which aims ‘to share, highlight, celebrate, discuss, problematise, find things out...’ about TEL through an online space. The lead for ‘The Learning Conversation’ will offer reflections on this and other initiatives across the institution involving trainee teachers, university subject tutors, librarians and staff in student support services who are using TEL to engage, enthuse and support students on campus and during placements in schools. The fourth paper reflects on the use of TEL to engage with trainee teachers in post-compulsory education. This sector of education and training is more fragmented than primary and secondary schools sectors and so the challenges of building a community of practice that can support the development of innovative practice are greater.

Altération de la régénération musculaire dans la maladie pulmonaire obstructive chronique

Altération de la régénération musculaire dans la maladie pulmonaire obstructive chronique. La maladie pulmonaire obstructive chronique (MPOC) est caractérisée par une obstruction bronchique irréversible et progressive. L’atrophie musculaire périphérique y est fréquente et a un impact négatif sur la capacité fonctionnelle et la survie des sujets atteints. Toutefois, on ignore si une altération du processus de régénération musculaire est un processus ayant cours dans l’atrophie musculaire périphérique. Le but de la présente thèse était donc d’étudier les cellules satellites, principales cellules responsables de la régénération musculaire dans les muscles périphériques de patients ayant une MPOC. Dans un premier temps, nous avons évalué l’historique de réplication du tissu musculaire et la sénescence des cellules satellites. Les changements morphologiques ayant lieu dans le muscle au cours de la progression de la maladie rendent le muscle plus susceptible aux dommages, induisant un raccourcissement prématuré des télomères. Un raccourcissement des télomères chez les sujets ayant une MPOC avec atrophie est concomitant avec une augmentation du nombre de cellules satellites sénescentes et de l’épuisement du potentiel de régénération compromettant le maintien de la masse musculaire chez ces sujets. Dans un deuxième et troisième temps, nous avons étudié les étapes amenant une cellule satellite vers une cellule musculaire dans les muscles périphériques et respiratoires de patients ayant une MPOC comparativement à des sujets contrôles. Les cellules satellites sont impliquées dans la réparation du tissu musculaire. Dans les cellules satellites provenant des sujets ayant une MPOC, une altération de la prolifération et de la différentiation a été observée. Ces résultats sont compatibles avec une altération de la régénération musculaire pouvant conduire à l’atrophie musculaire dans la MPOC. Le quatrième volet de ce projet s’intéressait à l’impact d’un entraînement en résistance sur l’activité des cellules satellites et le rôle joué par la myostatine dans ce contexte. La littérature montre que l’exercice en résistance est bien toléré et aide les patients ayant une MPOC à retrouver une meilleure qualité de vie. Cependant, il semble qu’ils n’y répondent pas tous aussi bien que les sujets contrôles. La capacité de réponse des cellules satellites à un entraînement en résistance semble inadéquate, suggérant ainsi un défaut de leur activation. Dans la dernière étude de cette thèse, nous avons voulu évaluer l’impact de l’inflammation systémique en étudiant SAA1, une protéine de phase aiguë et p21, une protéine du cycle cellulaire dans la dégradation des protéines des cellules musculaires. Les liens de causalité entre l’affection primaire et les différentes comorbidités demeurent nébuleux dans la MPOC. SAA1 et p21 sont augmentés dans les muscles squelettiques des patients ayant une MPOC et par ailleurs, SAA1 est capable d’induire la dégradation des protéines musculaires. Cette thèse expose les premiers éléments impliquant l’altération de la régénération musculaire avec la dysfonction musculaire observée chez les patients ayant une MPOC. Ces résultats vont certainement contribuer au développement de nouvelles thérapies et stratégies d’intervention dans le but d’améliorer la qualité de vie des personnes atteintes d’une MPOC. En somme, les travaux effectués dans le cadre de la présente thèse montrent que plusieurs mécanismes agissent de concert avec l’inactivité physique afin d’induire le phénotype dysfonctionnel dans les muscles des patients ayant une MPOC.

Research and application of Building Information Modelling (BIM) in the Architecture, Engineering and Construction (AEC) industry : a review and direction for future research

With an increasing level of collaboration amongst researchers, software developers and industry practitioners in the past three decades, building information modelling (BIM) is now recognized as an emerging technological and procedural shift within the architect, engineering and construction (AEC) industry. BIM is not only considered as a way to make a profound impact on the professions of AEC, but is also regarded as an approach to assist the industry to develop new ways of thinking and practice. Despite the widespread development and recognition of BIM, a succinct and systematic review of the existing BIM research and achievement is scarce. It is also necessary to take stock on existing applications and have a fresh look at where BIM should be heading and how it can benefit from the advances being made. This paper first presents a review of BIM research and achievement in AEC industry. A number of suggestions are then made for future research in BIM. This paper maintains that the value of BIM during design and construction phases is well documented over the last decade, and new research needs to expand the level of development and analysis from design/build stage to postconstruction and facility asset management. New research in BIM could also move beyond the traditional building type to managing the broader range of facilities and built assets and providing preventative maintenance schedules for sustainable and intelligent buildings

Public participation, values and interests in the procurement of infrastructure projects in Australia : a review and future research direction

In many countries, the main providers for major infrastructure projects are government or public agencies. Public infrastructure projects includes economic and social infrastructure such as transportation, education and health facilities. Most decision-making models for delivery of public infrastructure projects are heavily weighted towards financial/economic factors. In Australia, public participation is an essential instrument in the procurement of infrastructure and development within Australia. This study reviews the public participation, values and interests in the procurement of infrastructure projects in Australia, and identifies the research direction in this research area in order to improve the decision-making models that capture stakeholder social, economical and environmental concerns in infrastructure projects.

B2B e-marketplaces in the procurement supply chain of airlines: a strategic direction for the future?:a strategic direction for the future?

With the airline industry experiencing a global economic downturn, B2B e-Business is becoming more and more the focus of airlines’ strategies. More recently, airlines have studied intensively the potential of joint-procurement possibilities and have taken measures in creating consortia-led B2B e-Marketplaces as mediators for aggregating demand and to facilitate transactions. In academic literature, limited academic research has been undertaken in exploring the value creation of B2B e-Marketplace models in the aviation industry. The aim is to conduct a theoretical analysis to explore whether or not e-Marketplaces have the potential to add value to procurement in the aviation industry. The research focuses on the potential of B2B e-Marketplaces in terms of improving an airline’s competitiveness in its procurement value chain. The theoretical framework adopted supports the identification of barriers to success and critical success factors.

Electronic purchasing consortia:a procurement direction for the future?

In literature, there has been little empirical research investigation on purchasing consortium issues focusing on a detailed analysis of ICT-based procurement strategies. Based on the exploration of academic literature and a survey on e-Marketplaces / procurement service providers (PSPs) in the automotive and electronics industry sectors, an overall statement is proposed: Effective participation in electronic purchasing consortia can have the potential to enhance competitive advantage. Implementation therefore requires a clear and detailed understanding of the major process structures and drivers at the e-Marketplace / PSP level of analysis.

Correlating eye gaze direction, depth and vehicle information on an interactive map for driver training

The over represented number of novice drivers involved in crashes is alarming. Driver training is one of the interventions aimed at mitigating the number of crashes that involve young drivers. Experienced drivers have better hazard perception ability compared to inexperienced drivers. Eye gaze patterns have been found to be an indicator of the driver's competency level. The aim of this paper is to develop an in-vehicle system which correlates information about the driver's gaze and vehicle dynamics, which is then used to assist driver trainers in assessing driving competency. This system allows visualization of the complete driving manoeuvre data on interactive maps. It uses an eye tracker and perspective projection algorithms to compute the depth of gaze and plots it on Google maps. This interactive map also features the trajectory of the vehicle and turn indicator usage. This system allows efficient and user friendly analysis of the driving task. It can be used by driver trainers and trainees to understand objectively the risks encountered during driving manoeuvres. This paper presents a prototype that plots the driver's eye gaze depth and direction on an interactive map along with the vehicle dynamics information. This prototype will be used in future to study the difference in gaze patterns in novice and experienced drivers prior to a certain manoeuvre.

Predictors of future falls in Parkinson disease

Background: Falls are a major health and injury problem for people with Parkinson disease (PD). Despite the severe consequences of falls, a major unresolved issue is the identification of factors that predict the risk of falls in individual patients with PD. The primary aim of this study was to prospectively determine an optimal combination of functional and disease-specific tests to predict falls in individuals with PD. ----- ----- Methods: A total of 101 people with early-stage PD undertook a battery of neurologic and functional tests in their optimally medicated state. The tests included Tinetti, Berg, Timed Up and Go, Functional Reach, and the Physiological Profile Assessment of Falls Risk; the latter assessment includes physiologic tests of visual function, proprioception, strength, cutaneous sensitivity, reaction time, and postural sway. Falls were recorded prospectively over 6 months. ----- ----- Results: Forty-eight percent of participants reported a fall and 24% more than 1 fall. In the multivariate model, a combination of the Unified Parkinson's Disease Rating Scale (UPDRS) total score, total freezing of gait score, occurrence of symptomatic postural orthostasis, Tinetti total score, and extent of postural sway in the anterior-posterior direction produced the best sensitivity (78%) and specificity (84%) for predicting falls. From the UPDRS items, only the rapid alternating task category was an independent predictor of falls. Reduced peripheral sensation and knee extension strength in fallers contributed to increased postural instability. ----- ----- Conclusions: Falls are a significant problem in optimally medicated early-stage PD. A combination of both disease-specific and balance- and mobility-related measures can accurately predict falls in individuals with PD.

Panel studies of new venture creation: a methods-focused review and suggestions for future research

Longitudinal panel studies of large, random samples of business start-ups captured at the pre-operational stage allow researchers to address core issues for entrepreneurship research, namely, the processes of creation of new business ventures as well as their antecedents and outcomes. Here, we perform a methods-orientated review of all 83 journal articles that have used this type of data set, our purpose being to assist users of current data sets as well as designers of new projects in making the best use of this innovative research approach. Our review reveals a number of methods issues that are largely particular to this type of research. We conclude that amidst exemplary contributions, much of the reviewed research has not adequately managed these methods challenges, nor has it made use of the full potential of this new research approach. Specifically, we identify and suggest remedies for context-specific and interrelated methods challenges relating to sample definition, choice of level of analysis, operationalization and conceptualization, use of longitudinal data and dealing with various types of problematic heterogeneity. In addition, we note that future research can make further strides towards full utilization of the advantages of the research approach through better matching (from either direction) between theories and the phenomena captured in the data, and by addressing some under-explored research questions for which the approach may be particularly fruitful.
