Assisting End-users in Filling Out Web Services

With the quick advance of web service technologies, end-users can conduct various on-line tasks, such as shopping on-line. Usually, end-users compose a set of services to accomplish a task, and need to enter values to services to invoke the composite services. Quite often, users re-visit websites and use services to perform re-occurring tasks. The users are required to enter the same information into various web services to accomplish such re-occurring tasks. However, repetitively typing the same information into services is a tedious job for end-users. It can negatively impact user experience when an end-user needs to type the re-occurring information repetitively into web services. Recent studies have proposed several approaches to help users fill in values to services automatically. However, prior studies mainly suffer the following drawbacks: (1) limited support of collecting and analyzing user inputs; (2) poor accuracy of filling values to services; (3) not designed for service composition. To overcome the aforementioned drawbacks, we need maximize the reuse of previous user inputs across services and end-users. In this thesis, we introduce our approaches that prevent end-users from entering the same information into repetitive on-line tasks. More specifically, we improve the process of filling out services in the following 4 aspects: First, we investigate the characteristics of input parameters. We propose an ontology-based approach to automatically categorize parameters and fill values to the categorized input parameters. Second, we propose a comprehensive framework that leverages user contexts and usage patterns into the process of filling values to services. Third, we propose an approach for maximizing the value propagation among services and end-users by linking a set of semantically related parameters together and similar end-users. Last, we propose a ranking-based framework that ranks a list of previous user inputs for an input parameter to save a user from unnecessary data entries. Our framework learns and analyzes interactions of user inputs and input parameters to rank user inputs for input parameters under different contexts.

The Discursive double game of EMU reform: the clash of titans between French White Knight and German Iron Lady. Paper presented at the 9th Biennial Conference European Community Studies Association–Canada (ECSA-C), Ottawa, Ontario, April 27-28, 2012

From the Introduction. In the aftermath of the EU’s enlargement towards Central and Eastern Europe, many scholars and observers of European integration were proclaiming that the French-German “engine” of Europe had come to an end. The political legitimacy of French-German initiatives was contested by coalitions of smaller member states and the ‘new Europe’ was calling for new leadership dynamics. However, the experience of the Eurozone debt crisis provided dramatic evidence that no alternative to the Franco-German partnership has yet to emerge in the enlarged EU. In a time of existential crisis, Franco-German initiatives appear to have remained the basic dynamic of integration. However, unlike in the past, agreements on steps forward have proven to be particularly difficult. This is largely due to these countries’ contrasting political economic policy ideas, cultures, and practices....the paper analyses the ideational ‘frames’ of the two leaders while tracing their discursive interactions against changing background conditions since the European debt crisis was triggered by Greece in October 2009 until the last measures taken in 2012 before the French Presidential elections. The empirical analysis is based on a systematic corpus of press conferences and media interviews by Nicolas Sarkozy and Angela Merkel after European summits. It is complemented by a number of press interviews including some given by their respective Finance Ministers) and important speeches in that same period of time.

Entre cahiers et biberons : les enjeux de la conciliation études/famille des mères adolescentes au Gabon

Ce travail de recherche s’est intéressé aux mères adolescentes du Gabon, pays d’Afrique Centrale. S’inscrivant en faux contre l’idée préconçue selon laquelle les grossesses à l’adolescence conduisent inéluctablement au décrochage scolaire, les résultats de recherche présentés dans ce document rendent plutôt compte d’expériences inverses, à savoir celles des mères adolescentes qui parviennent à persévérer dans leurs études. Le présent mémoire vise à comprendre et à analyser le vécu des jeunes filles mères scolarisées. Il questionne le parcours de vie de ces « mamans ados » et conséquemment les mécanismes qui leur permettent de concilier études et maternité. La démarche repose sur une méthode qualitative. Des entretiens semi-directifs auprès de 18 jeunes filles mères scolarisées ont été conduits à Libreville, capitale gabonaise. Les jeunes filles rencontrées étaient âgées de 15 à 19 ans. Les entrevues ont été enregistrées et retranscrites. Quels sont les facteurs favorisant la conciliation études/maternité chez les jeunes filles ? Nos données ont permis de mettre en évidence quatre facteurs cruciaux à cet égard. Ces facteurs sont premièrement, une capacité d’organisation et un degré d’auto-responsabilisation très poussés chez ces jeunes filles ; deuxièmement, l’activation d’un soutien important de la part du réseau familial ; troisièmement, une implication et des aides importantes apportées par le père de l’enfant ; enfin, une valorisation affirmée de l’éducation de la part des parents de la jeune mère. Il ressort aussi de nos analyses que moyennant au moins l’un, sinon plusieurs, de ces facteurs, les jeunes mères adolescentes à Libreville parviennent à mener de front études et maternité. Cela veut dire que le décrochage scolaire chez les mères adolescentes n’est pas une fatalité si des formes d’accompagnement et de soutien existent.

Review of the Economic Development in the Western Balkan States. OSW STUDIES No. 19, 2005-08-10

Foreword. Ten years after the end of the armed conflict, the Western Balkans1 are still being considered as the “land of the unsuccessful policies”. Enormous financial and technical assistance transferred by the International Community has not managed to meet the goals of integrating the region within itself as well as within the European markets. Explanation for this can be found in the consequences of the war and the remnants of the socialist state. The complexity of current institutional/ political arrangements combined with the limited willingness of the regional actors to introduce and implement much of the needed reforms have additionally contributed to the current state of affairs. The economy and politics in the region intertwine to an extent as probably in none of the other post-communist states. Therefore, the paper presents the recent economic performance of the Western Balkan countries in the light of their limited institutional development and lack of efficient regional cooperation. The paper discusses the importance of foreign direct investments’ inflow for the economic growth of the “latecomer” states and presents major drawbacks which limit the influx of the foreign capital to the region. It presents private sector activity and regional cooperation programmes. It discusses the role of the International Community with the main focus on the activities of the European Union. The EU is examined not only as the main aid donor but more importantly as a foreign trade partner. Furthermore, it analyses the impact of the presence of the International Community and their strategies towards the region with the special attention to the EU. Finally, it presents recommendations for the improvement of the economic performance in light of the enhanced political cooperation between the EU and the region.

Ukraine on the financial front – the problem of Ukraine’s foreign public debt. OSW COMMENTARY NUMBER 178|05.08.2015

One of the key challenges that Ukraine is facing is the scale of its foreign debt (both public and private). As of 1st April it stood at US$ 126 billion, which is 109.8% of the country’s GDP. Approximately 45% of these financial obligations are short-term, meaning that they must be paid off within a year. Although the value of the debt has fallen by nearly US$ 10 billion since the end of 2014 (due to the private sector paying a part of the liabilities), the debt to GDP ratio has increased due to the recession and the depreciation of the hryvnia. The value of Ukraine’s foreign public debt is also on the rise (including state guarantees); since the beginning of 2015 it has risen from US$ 37.6 billion to US$ 43.6 billion. Ukraine does not currently have the resources to pay off its debt. In this situation a debt restructuring is necessary and this is one of the top priorities for the Ukrainian government as well as for the International Monetary Fund (IMF) and its assistance programme. Without this it will be much more difficult for Ukraine to overcome the economic crisis.

Age, pollen and spores of ODP Site 175-1082

The present-day condition of bipolar glaciation characterized by rapid and large climate fluctuations began at the end of the Pliocene with the intensification of the Northern Hemisphere continental glaciations. The global cooling steps of the late Pliocene have been documented in numerous studies of Ocean Drilling Program (ODP) sites from the Northern Hemisphere. However, the interactions between oceans and between land and ocean during these cooling steps are poorly known. In particular, data from the Southern Hemisphere are lacking. Therefore I investigated the pollen of ODP Site 1082 in the southeast Atlantic Ocean in order to obtain a high-resolution record of vegetation change in Namibia between 3.4 and 1.8 Ma. Four phases of vegetation development are inferred that are connected to global climate change. (1) Before 3 Ma, extensive, rather open grass-rich savannahs with mopane trees existed in Namibia, but the extension of desert and semidesert vegetation was still restricted. (2) Increase of winter rainfall dependent Renosterveld-like vegetation occurred between 3.1 and 2.2 Ma connected to strong advection of polar waters along the Namibian coast and a northward shift of the Polar Front Zone in the Southern Ocean. (3) Climatically induced fluctuations became stronger between 2.7 and 2.2 Ma and semiarid areas extended during glacial periods probably as the result of an increased pole-equator thermal gradient and consequently globally enhanced atmospheric circulation. (4) Aridification and climatic variability further increased after 2.2 Ma, when the Polar Front Zone migrated southward and the influence of Atlantic moisture brought by the westerlies to southern Africa declined. It is concluded that the positions of the frontal systems in the Southern Ocean which determine the locations of the high-pressure cells over the South Atlantic and the southern Indian Ocean have a strong influence on the climate of southern Africa in contrast to the climate of northwest and central Africa, which is dominated by the Saharan low-pressure cell.

Tab. 1: Rates of advance of the frontal push-moraines of 19 lobes in front of an approx. 4.5 km long margin of the Kötlujökull

In the last years masses of ice, about 5 km long, have been protruding from the lowest part of an advancing glacier margin of the Kötlujökull in Southern Iceland. In the summer of 1983, they appeared as sediment-covered lobes, 10-60 m long, bordering the glacier rnargin like agarland. 1 to 3 push-rnoraines without ice core, rnostly sickle-shaped, occured first in the frontal parts of the lobes: behind thern came several ice-cored moraines with heights of up to several metres. The active ice in front of the precipice of the glacier is called the "glacier-foot" in this paper. The digging out of 9 lobes and the measuring of the advance of 19 lobes showed that in most cases this glacierfoot had split up at its distal end into several plate- or stem-shaped pieces of ice which were situated one upon the other, separated by moraine deposits and proceeding irregularly into the foreland at the rate of several mm/h, The sometimes different rate of advance in the same lobe and different rates of advanee in adjoining lobes (some being entirely inactive) point to a type of rnovement which is independent of the general advance of the glacier. Research in the winter of 1983/84 showed less activity in 3 examined lobes, but the activity had not ceased. The advancement of the lower parts of the glacier-foot into and across the sands of the foreland implies the following genesis of pushmoraines: Shoving off a plate of sand, folding it and pushing it over the foreland at average rates of up to 7,2 mm/h, according to the investigations in thc summer of 1983. At a certain stage of the folding process, new folds begin to develop in front of the old, and the old folds are shifted onto the backslope of thc folds in front of them until they are completely unired. In this way, "püe-moraines" arise, which become higher and higher. They include two or more folds declining towards the glacier. Systems of small moraines presumably of the same genesis occur on old moraine areas in front of the Kötlujökull. The possible cause of formation of a glacier-foot is discussed, and the moraines of the Kötlujökull are compared with certain pleistocene push-moraines.
