Erweiterung des Dokumentenservers DSpace: Internationalisierung und Implementation des URN-Systems zur permanenten Dokumentenadressierung

At first a small overview is given about the disposition of document ser- vers in the scientific publication process. Then, institutional repositories are introduced by their key features and the benefits of establishing them as a central repository in the university context. A specific solution was chosen on behalf of the requirements of the Uni- versity Library of Kassel, Germany. The software Dspace was chosen but needs to be extended by • internationalization • use of the urn:nbn scheme as persisten identifier. DSpace’s features are shortly described, followed by the process of rever- se engeneering to achieve requirements needed for the implementation of the missing functionality. Adjacent tasks implement the needed featu- res using SUN’s Standard Tag Library for internationalization and some modifications in two classes for use of the urn:nbn scheme as persistent identifier. At the end, a short view on the future of institutional repositories is taken, furthermore some local long-term objectives on DSpace are dis- cussed.

Madeira wine vinification process: analysis and control

The present study was done in collaboration with J. Faria e Filhos company, a Madeira wine producer, and its main goal was to fully characterize three wines produced during 2014 harvest and identify possible improving points in the winemaking process. The winemaking process was followed during 4 weeks, being registered the amounts of grapes received, the fermentation temperatures, the time at which fermentation was stopped and evolution of must densities until the fortification time. The characterization of musts and wines was done in terms of density, total and volatile acidity, alcohol content, pH, total of polyphenol, organic acids composition, sugars concentration and the volatile profile. Also, it was developed and validated an analytical methodology to quantify the volatile fatty acids, namely using SPME-GC-MS. Briefly, the following key features were obtained for the latter methodology: linearity (R2=0.999) e high sensitivity (LOD =0.026-0.068 mg/L), suitable precision (repeatability and reproducibility lower than 8,5%) and good recoveries (103,11-119,46%). The results reveal that fermentation temperatures should be controlled in a more strictly manner, in order to ensure a better balance in proportion of some volatile compounds, namely the esters and higher alcohols and to minimize the concentration of some volatiles, namely hexanoic, octanoic and decanoic acids, that when above their odours threshold are not positive for the wine aroma. Also, regarding the moment to stop the fermentation, it was verified that it can be introduced changes which can also be benefit to guarantee the tipicity of Madeira wine bouquet.

Repositories for open education and improving discoverability of OERs

Presentation given at 2016 Association for Learning Technology conference at University of Warwick (ALT2016). This presentation shares key findings from my MSc thesis on discoverability strategies for OERs after a small scale study into Jisc UKOER projects. The origins, key features and recent improvements to EdShare, the OER repository solution which is available through EPrints Services at the University of Southampton, is highlighted. Repositories provide an excellent way of archiving, preserving and managing content, but is this enough for OERs. OERs are about more than simply sharing, and this presentation highlighted a number of development areas under consideration for EdShare, to become a more open digital space.

Nazi Wireless Propaganda: Lord Haw-Haw and British Public Opinion in the Second World War

This is the first book devoted exclusively to the analysis of the Nazis' radio effort against the United Kingdom during the Second World War. It traces the development of the German propaganda service and looks to erode the myth surrounding Lord Haw-Haw -the 'superpropagandist'. Propaganda is presented in context: the purposes behind it, the changing patterns, themes, styles, and techniques employed, and the impact upon the target audience and its morale. An analysis of the Nazi wireless broadcasts to Britain for the whole of the Second World War reveals a sophisticated and intelligent propaganda assault on the social and economic fabric of British society. In the end the British failed to succumb to the stupefying effects of Nazi propaganda and they traditionally congratulate themselves upon the national unity which immunised them against it. The author argues that this traditional view disguises a more complex, less appealing reality. Free CD Includes a CD of 24 German wartime broadcasts to Britain Key Features: *Exposition of organisational structure of Nazi wireless for the UK *Detailed analysis of style and content of propaganda broadcasts *Careful and critical re-appraisal of British domestic morale and national unity *CD insert of 24 recordings of Nazi broadcasters including William Joyce, John Amery, Edward Dietze, Norman Baillie-Stewart, Edward Bowlby and 'Black' propaganda broadcasts

Evaluation of Tottenham Thinking Space Pilot: Final Report. Research Report 11.

This reports summarises research that began in March 2014 and was completed in October 2015 by an experienced inter-disciplinary research team from the Centre for Social Justice and Change and Psycho-Social Research Group, School of Social Sciences, the University of East London (UEL) and included Dr Yang Li from the Centre for Geo-Information Studies, UEL, for the first phase of the study. Tottenham ‘Thinking Space’ (TTS) was a pilot therapeutic initiative based in local communities and delivered by the Tavistock & Portman NHS Foundation Trust and funded by the London Borough of Haringey Directorate of Public Health. TTS aimed to improve mental health and enable and empower local communities. TTS was situated within a mental health agenda that was integral to Haringey’s Health and Wellbeing Strategy 2012-2015 and aimed to encourage people to help themselves and each other and develop confident communities. On the one hand TTS was well-suited to this agenda, but, on the other, participants were resistant to, and were trying to free themselves from labelling that implied ‘mental health difficulties’. A total of 243 meetings were held and 351 people attended 1,716 times. The majority of participants attended four times or less, and 33 people attended between 5 and 10 times and 39 people attended over 10 times. Attending a small number of times does not necessarily mean that the attendee was not helped. Attendees reflected the ethnic diversity of Tottenham; 29 different ethnic groups attended. The opportunity to meet with people from different cultural backgrounds in a safe space was highly valued by attendees. Similarly, participants valued the wide age range represented and felt that they benefited from listening to inter-generational experiences. The majority of participants were women (72%) and they were instrumental in initiating further Thinking Spaces, topic specific meetings, the summer programme of activities for mothers and young children and training to meet their needs. The community development worker had a key role in implementing the initiative and sustaining its growth throughout the pilot period. We observed that TTS attracted those whose life experiences were marked by personal struggle and trauma. Many participants felt safe enough to disclose mental health difficulties (85% of those who completed a questionnaire). Participants also came seeking a stronger sense of community in their local area. Key features of the meetings are that they are democratic, non-judgemental, respectful, and focussed on encouraging everyone to listen and to try to understand. We found that the therapeutic method was put in place by high quality facilitators and health and personal outcomes for participants were consistent with those predicted by the underpinning psychoanalytical and systemic theories. Outcomes included a reduction in anxieties and improved personal and social functioning; approximately two thirds of those who completed a questionnaire felt better understood, felt more motivated and more hopeful for the future. The overwhelming majority of survey respondents also felt good about contributing to their community, said that they were more able to cooperate with others and accepting of other cultures, and had made new friends. Participants typically had a better understanding of their current situation and how to take positive action; of those who completed a questionnaire, over half felt more confident to seek support for a personal issue and to contact services. Members of TTS supported each other and instilled hope and build community-mindedness that reduced social isolation.

Return to Hanging Rock: Lost Children in a Gothic Landscape

Using the philosophical position of phenomenology this article examines the ways in which ideas of wildness combine with Australian Gothic tropes such as the white colonial lost child and the bush as a haunted locale to compose key features of an Australian Ecogothic. Joan Lindsay’s enigmatic novel Picnic at Hanging Rock (1967) has prompted scholars such as Lesley Kathryn Hawkes to describe how in Australian literature for both adults and children ‘the environment is far more than a setting or backdrop against which the plot takes place’ (Hawkes, 2011,67). On St Valentine’s Day in 1900 three young Australian girls and their teacher disappear from a school picnic at the ancient site of Mount Macedon in Victoria. The analysis, which focuses on Lindsay’s posthumously published chapter eighteen (1987) examines how elements of the material, sensing world combine with the mythological or sacred to connect the human protagonists with the gothic landscape they inhabit. The resulting intersubjectivity problematizes colonial ideology and unsettles notions of national identity.

THE MARKETING OF SOCIAL ENTERPRISES: Understanding the concepts of marketing and market orientation of social enterprises within the context of Pakistani market

The concepts of social entrepreneurship and social enterprises have been extensively discussed in the previous two decades, yet the topic is still not matured yet. Most of the available literature is focused on defining these terms. Similarly, limited number of authors has discussed the marketing function of these enterprises or how marketing is interpreted in social entrepreneurship models. However, there is a plethora of literature on marketing entailing many different theories, amongst which the newest one is the “market orientation concept”. Market orientation is a mix of customer orientation, competitor orientation and inter-functional coordination suggesting marketing to be a part of the business philosophy. This study focuses on the marketing and market orientation of social enterprises while giving an overview of the literature of marketing and market orientation in social enterprises. This study aims to provide two basic questions, 1) what is the literature on marketing and market orientation of social enterprises while explaining the literature of social enterprises in Pakistan and 2) how these concepts are interpreted in social enterprises in Pakistani market. Key features of research methodology include case study approach while conducting thematic analysis using thematic networks. The results indicate that only a limited number of authors have discussed market orientation concept in social enterprises. The results from the interview data indicate the usage of marketing by a firm unconsciously without a specific marketing department. In addition to that, it has been found that in social enterprise world competition is tackled through a win-win approach with a view that many enterprises working for society improve the society which is the basic mission of any social enterprise. The data also showed that in Pakistani market, social enterprise concept is not legally used yet, which allows for more room for innovation. This study intends to give a new perspective to the theorists to use market orientation concept in social enterprises and also to managers to use marketing as their business philosophy in order to satisfy the stakeholders for better delivery of their businesses and as well for social good.

A Binary Classifier for Test Case Feasibility Applied to Automatically Generated Tests of Event-Driven Software

Modern software application testing, such as the testing of software driven by graphical user interfaces (GUIs) or leveraging event-driven architectures in general, requires paying careful attention to context. Model-based testing (MBT) approaches first acquire a model of an application, then use the model to construct test cases covering relevant contexts. A major shortcoming of state-of-the-art automated model-based testing is that many test cases proposed by the model are not actually executable. These \textit{infeasible} test cases threaten the integrity of the entire model-based suite, and any coverage of contexts the suite aims to provide. In this research, I develop and evaluate a novel approach for classifying the feasibility of test cases. I identify a set of pertinent features for the classifier, and develop novel methods for extracting these features from the outputs of MBT tools. I use a supervised logistic regression approach to obtain a model of test case feasibility from a randomly selected training suite of test cases. I evaluate this approach with a set of experiments. The outcomes of this investigation are as follows: I confirm that infeasibility is prevalent in MBT, even for test suites designed to cover a relatively small number of unique contexts. I confirm that the frequency of infeasibility varies widely across applications. I develop and train a binary classifier for feasibility with average overall error, false positive, and false negative rates under 5\%. I find that unique event IDs are key features of the feasibility classifier, while model-specific event types are not. I construct three types of features from the event IDs associated with test cases, and evaluate the relative effectiveness of each within the classifier. To support this study, I also develop a number of tools and infrastructure components for scalable execution of automated jobs, which use state-of-the-art container and continuous integration technologies to enable parallel test execution and the persistence of all experimental artifacts.

Targeting the serrated pathway of colorectal cancer with mutation in BRAF

A recently acknowledged morphological pathway to colorectal cancer originates from precursor polyps with a serrated appearance due to branching and folding of the colon epithelium. This serrated origin accounts for up to 30% of all colorectal tumors but these are heterogeneous regarding molecular characteristics and patient outcome. Here we review the current knowledge about the classification of this tumor subtype and its association with five key features: mutation status of the BRAF or KRAS genes, the CpG island methylation phenotype, microsatellite instability, immune cell infiltration, and overexpression of GTPase RAC1b. Subsequently, available therapeutic approaches for targeting these molecular characteristics are presented and critically discussed.

Enzymatic upgrading of eucalypt paper-grade kraft pulp within dissolving pulp production

Dissolving-grade pulps are commonly used for the production of cellulose derivatives and regenerated cellulose. High cellulose content, low content of non-cellulosic material, high brightness, a uniform molecular weight distribution and high cellulose reactivity are the key features that determine the quality of a dissolving pulp. The first part of this work was an optimization study regarding the application of selected enzymes in different stages of a new purification process recently developed in Novozymes for purifying an eucalypt Kraft pulp into dissolving pulp, as an alternative to the pre-hydrolysis kraft (PHK) process. In addition, a viscosity reduction was achieved by cellulase (endoglucanase) treatment in the beginning of the sequence, while the GH11 and GH10 xylanases contributed to boost the brightness of the final pulp. The second part of the work aimed at exploring different auxiliary enzyme activities together with a key xylanase towards further removal of recalcitrant hemicelluloses from a partially bleached Eucalypt Kraft pulp. The resistant fraction (ca. 6% xylan in pulp) was not hydrolysable by the different combinations of enzymes tested. Production of a dissolving pulp was successful when using a cold caustic extraction (CCE) stage in the end of the sequence O-X-DHCE-X-HCE-D-CCE. The application of enzymes improved process efficiency. The main requirements for the production of a dissolving pulp (suitable for viscose making) were fulfilled: 2,7% residual xylan, 92,4% of brightness, a viscosity within the values of a commercial dissolving pulp and increased reactivity.

Legal Framework for Cross-Regional Networks: The Case of Services and Migration

Paper prepared by Marion Panizzon and Charlotte Sieber-Gasser for the International Conference on the Political Economy of Liberalising Trade in Services, Hebrew University of Jerusalem, 14-15 June 2010 Recent literature has shed light on the economic potential of cross-border networks. These networks, consisting of expatriates and their acquaintances from abroad and at home, provide the basis for the creation of cross-border value added chains and therewith the means for turning brain drain into brain circulation. Both aspects are potentially valuable for economic growth in the developing world. Unilateral co-development policies operating through co-funding of expatriate business ventures, but also bilateral agreements liberalising circular migration for a limited set of per-sons testify to the increasing awareness of governments about the potential, which expatriate networks hold for economic growth in developing countries. Whereas such punctual efforts are valuable, viewed from a long term perspective, these top-down, government mandated Diaspora stimulation programs, will not replace, this paper argues, the market-driven liberalisation of infrastructure and other services in developing countries. Nor will they carry, in the case of circular labour migration, the political momentum to liberalise labour market admission for those non-nationals, who will eventually emerge as the future transnational entrepreneurs. It will take a combination of mode 4 and infrastructure services openings-cum regulation for countries at both sides of the spectrum to provide the basis and precondition for transnational business and entrepreneurial networks to emerge and translate into cross-border, value added production chains. Two key issues are of particular relevance in this context: (i) the services sector, especially in infrastructure, tends to suffer from inefficiencies, particularly in developing countries, and (ii) labour migration, a highly complex issue, still faces disproportionately rigid barriers despite well-documented global welfare gains. Both are hindrances for emerging markets to fully take advantage of the potential of these cross-border networks. Adapting the legal framework for enhancing the regulatory and institutional frameworks for services trade, especially in infrastructure services sectors (ISS) and labour migration could provide the incentives necessary for brain circulation and strengthen cross-border value added chains by lowering transaction costs. This paper analyses the shortfalls of the global legal framework – the shallow status quo of GATS commitments in ISS and mode 4 particular – in relation to stimulating brain circulation and the creation of cross-border value added chains in emerging markets. It highlights the necessity of adapting the legal framework, both on the global and the regional level, to stimulate broader and wider market access in the four key ISS sectors (telecommunications, transport, professional and financial services) in developing countries, as domestic supply capacity, global competitiveness and economic diversification in ISS sectors are necessary for mobilising expatriate re-turns, both physical and virtual. The paper argues that industrialised, labour receiving countries need to offer mode 4 market access to wider categories of persons, especially to students, graduate trainees and young professionals from abroad. Further-more, free trade in semi-finished products and mode 4 market access are crucial for the creation of cross-border value added chains across the developing world. Finally, the paper discusses on the basis of a case study on Jordan why the key features of trade agreements, which promote circular migration and the creation of cross-border value added chains, consist of trade liberalisation in services and liberal migration policies.
