No / The Atlantic burden-sharing debate during the early part of the twenty-first century is shaping up to be very different from those of NATO's first fifty years. The resources needed for direct defence of western Europe have fallen sharply, and further cuts are possible. The gradual strengthening of European cooperation means that the EU is becoming an actor in its own right in many international regimes. Debates about which countries are pulling their weight internationally are also taking into account contributions to non-military international public goods¿financing EU enlargement, aiding the Third World, reducing emissions of climate-damaging pollutants. In this new multidimensional debate, it becomes more apparent that states that contribute more to one regime often do less than most in another. Germany, for example, is concerned about its excessive contribution to the costs of EU enlargement, but it spends considerably less than France and the UK on defence. European countries contribute three times as much as the United States to Third World aid, and will soon pay almost twice as much into the UN budget. Yet they were dependent on the US to provide most of the military forces in the 1999 Kosovo conflict, and would be even more dependent in the event of a future Gulf war. This widening of the burden-sharing debate contains both dangers and opportunities. It could lead to a fragmentation of the Atlantic dialogue, with each side talking past the other on an increasing number of issues, ranging from global warming to Balkan peacekeeping. In order to avoid such a dangerous situation, the US and European states should maintain the principle that all must make a contribution to efforts to tackle common problems, whether it be through troops in Kosovo or commitments to reducing greenhouse gas emissions. Yet there should also be some flexibility in defining who does how much. The preparedness of some countries to lead, by doing more, will be essential if international cooperation is to have a chance to work.

The following study categorises, summarises and analyses research on unequal participation of social groups in Nordic higher education. While it does not give an exhaustive account of all research, the ambition has been to capture the main strands of contemporary literature and its results. I categorise the literature into three main research traditions, as well as into studies that may best be characterised by their object of study. This typology forms the structure in which research is presented in the study. The summary of research results show that in parallel with the efforts to expand higher education and include larger parts of the population, the relationship between family background and children’s years of education has weakened and the rate of participation in higher education has increased among underrepresented groups. At the same time, however, patterns where students tend to study different study programmes or at different higher education institutions depending on gender and social or national background have remained largely intact, and in some cases even grown stronger. These differences in participation rates and enrolment patterns can be traced to inequalities in school achievement, unequal access to knowledge and information, differences in family support and expectations from the social environment, different horizons of opportunities, as well as different preferences regarding the length of the study programme, its degree of labour market connection and the importance placed on the geographical proximity to family and friends. One of the contributions of the analysis is showing how questions and methods in different research traditions generate different types of results, which at first glance may seem incompatible. Upon closer inspection, however, the research results in fact paint a highly congruent picture. A consistent theme throughout is how more detailed, multidimensional or intersectional indicators and classifications of education, social background or other social groupings often reveal important differences and inequalities that are invisible in studies that use more aggregated or linear indicators and groupings. / <p>Uppsatsen skrevs ursprungligen i rapportform på uppdrag av Universitetskanslersämbetet (UKÄ) och publicerades 2021 inom ramen för UKÄ:s regeringsuppdrag att utvärdera lärosätenas arbete med breddad rekrytering.

Un grand nombre d'études ont été faites dans le domaine de l'Optimisation Stochastique en général et les Algorithmes Génétiques en particulier. L'essentiel des nouveaux développements ou des améliorations faites sont alors testés sur des jeux de tests très connus tels que BBOB, CEC, etc. conçus de telle manière que soient présents les principaux défis que les optimiseurs doivent relever : non séparabilité, multimodalité, des vallées où le gradient est quasi-nul, et ainsi de suite. La plupart des études ainsi faites se déroulent via une application directe sur le jeu de test, optimisant un nombre donné de variables pour atteindre un critère précis. La première contribution de ce travail consiste à étudier l'impact de la remise en cause de ce fonctionnement par deux moyens : le premier repose sur l'introduction d'un grand nombre de variables qui n'ont pas d'impact sur la valeur de la fonction optimisée ; le second quant à lui relève de l'étude des conséquences du mauvais conditionnement d'une fonction en grande dimension sur les performances des algorithmes d'optimisation stochastique. Une deuxième contribution se situe dans l'étude de l'impact de la modification des mutations de l'algorithme CMA-ES,où, au lieu d'utiliser des mutations purement aléatoires, nous allons utiliser des mutations quasi-aléatoires. Ce travail introduit également la ``Sieves Method'', bien connue des statisticiens. Avec cette méthode, nous commençons par optimiser un faible nombre de variables, nombre qui est ensuite graduellement incrémenté au fil de l'optimisation.Bien que les jeux de tests existants sont bien sûr très utiles, ils ne peuvent constituer que la première étape : dans la plupart des cas, les jeux de tests sont constitués d'un ensemble de fonctions purement mathématiques, des plus simples comme la sphère, aux plus complexes. Le but de la conception d'un nouvel optimiseur, ou l'amélioration d'un optimiseur existant, doit pourtant in fine être de répondre à des problèmes du monde réel. Ce peut-être par exemple la conception d'un moteur plus efficace, d'identifier les bons paramètres d'un modèle physique ou encore d'organiser des données en groupes.Les optimiseurs stochastiques sont bien évidemment utilisés sur de tels problèmes, mais dans la plupart des cas, un optimiseur est choisi arbitrairement puis appliqué au problème considéré. Nous savons comment les optimiseurs se comparent les uns par rapport aux autres sur des fonctions artificielles, mais peu de travaux portent sur leur efficacité sur des problèmes réels. L'un des principaux aspects de des travaux présentés ici consiste à étudier le comportement des optimiseurs les plus utilisés dans la littérature sur des problèmes inspirés du monde réel, voire des problèmes qui en viennent directement. Sur ces problèmes, les effets des mutations quasi-aléatoires de CMA-ES et de la``Sieves Method'' sont en outre étudiés. / A lot of research is being done on Stochastic Optimisation in general and Genetic Algorithms in particular. Most of the new developments are then tested on well know testbeds like BBOB, CEC, etc. conceived to exhibit as many pitfalls as possible such as non-separability, multi-modality, valleys with an almost null gradient and so on. Most studies done on such testbeds are pretty straightforward, optimising a given number of variables for there cognized criterion on the testbed. The first contribution made here is to study the impact of some changes in those assumptions, namely the effect of supernumerary variables that don't change anything to a function evaluation on the one hand, and the effect of a change of the studied criterion on the other hand. A second contribution is in the modification of the mutation design for the algorithm CMA-ES, where we will use Quasi-Random mutations instead of purely random ones. This will almost always result in a very clear improvement ofthe observed results. This research also introduces the Sieves Method well known in statistics, to stochastic optimisers: by first optimising a small subset of the variables and gradually increasing the number of variables during the optimization process, we observe on some problems a very clear improvement. While artificial testbeds are of course really useful, they can only be the first step: in almost every case, the testbeds are a collection of purely mathematical functions, from the simplest one like the sphere, to some really complex functions. The goal of the design of new optimisers or the improvement of an existing one is however, in fine, to answer some real world question. It can be the design of a more efficient engine, finding the correct parameters of a physical model or even to organize data in clusters. Stochastic optimisers are used on those problems, in research or industry, but in most instances, an optimiser ischosen almost arbitrarily. We know how optimisers compare on artificial functions, but almost nothing is known abouttheir performances on real world problems. One of the main aspect of the research exposed here will be to compare someof the most used optimisers in the literature on problems inspired or directly coming from the real-world. On those problems, we will additionally test the efficiency of quasi-random mutations in CMA-ES and the Sieves-Method.

Europe experienced the destruction of numerous infrastructures during World War II, followed by a reflation and a strong economic growth during the next two decades allowing a more perennial and durable situation. A classical bridge lasting in general around 80 years, one should observe that these constructions built after the war will have to be either replaced either seriously strengthened in a few years. Besides, since the needs also vary over time, transportation infrastructures built during those years might not be adapted to the actual needs anymore – some bridges might thus have to be widened. A case study has been chosen in order to simulate under which conditions the widening of such a bridge can be performed. This road bridge, located in Vierzon in France, is rather simple since it is made of simply supported prestressed concrete beams and of reinforced concrete piers. It has been chosen in particular for its reduced size – three spans of 30 m each and two road lanes – that corresponded well to this project. Based on some data provided when the bridge was initially built and on a visual inspection, this project suggests six technical solutions to double the actual amount of lanes. An evaluation of the performance of the solutions according to three criteria – durations of works, cost of the works, and environmental impact – is made in order to give recommendations regarding the optimal solution. The results show that in spite of being installed quickly, adding steel beams is more expensive and has a greater impact on the environment than adding prestressed concrete beams. Regarding the modification of piers, the solution suggesting widening the existing piers is preferable than adding new extra piers according to all the criteria. Consequently, among all the solutions analysed, the optimal one is also the simplest one. Finally, the limits of the study and some suggestions for improvements are indicated.

This research investigates the influence of layout and design on the severity of trail degradation. Previous trail studies have been restricted by relatively small study areas which provide a limited range of environmental conditions and therefore produce findings with limited applicability; this research improves on this limitation by analyzing a representative sample of the Appalachian Trail with significant ecological diversity. Most trail science studies have also focused on a singular form of trail degradation, whereas this study investigates trail soil loss, widening and muddiness, providing a more cohesive analysis and revealing interrelationships between trail degradation processes. ANOVA testing of the mean values of three trail impact indicators for trail transects within several trail layout frameworks confirms the broad relevance of core trail design principles, specifically the sustainability advantages of trails with low grades and side-hill alignments. Findings also reveal the importance of landform grade in determining the susceptibility of trails to degradation and the influence of routing decisions; these relationships have received relatively little attention in the literature. The results also reveal several methodological considerations for trail alignment metrics and trail impact indicators. / Master of Science / Natural surfaced trails are an essential infrastructure component in parks and protected natural areas. They provide transportation routes through otherwise undeveloped areas and outdoor recreation opportunities for hikers, mountain bikers, and equestrians. Over time, recreational use and natural processes such as rainfall can lead to negative ecological impacts that damage trail treads in ways that impair their utility for visitors and require costly repairs. Environmental factors like unstable soils or extreme precipitation can make trails more susceptible to degradation. However, sustainable trail layouts and effective maintenance can reduce the rate and severity of degradation. This research investigates the influence of trail layout on three chief forms of trail degradation: trail soil loss, muddiness, and widening. Many trail science studies have occurred in small protected natural areas where the limited range of represented environmental conditions reduces the applicability of their findings in dissimilar settings. This study investigates a dataset from a large and ecologically diverse representative sample of the entire Appalachian Trail from Georgia to Maine which significantly broadens the relevance of its findings. Furthermore, many previous trail studies have focused on single forms of trail degradation whereas this study which investigates three, which provides a more cohesive analysis and reveals interrelationships between impacts. Findings confirm the broad pertinence of core sustainable trail design principles, specifically the benefits of low trail grades and side-hill alignments, and suggests that landform grade is an important factor which has received little attention in the literature. The study also revealed several methodological improvements and considerations which may be useful to trail scientists and practitioners.

Tanzania is among the poorest countries in the world, with most of its population living in rural areas. Like most other developing countries, rural households' access to financial services is very limited. The government has adopted series of economic reform measures since mid-1980s that include financial liberalization. Liberalization of the financial sector facilitated participation of private financial institutions, restructuring of public financial institutions and privatization, elimination of interest rate controls, credit allocation and targeting. In addition, the role of the Bank of Tanzania in supervision and regulation of financial institutions was strengthened. Following the privatization of the financial sector, the number of financial service providers increased and diversified, which include commercial banks, development banks, insurance and social security funds, and capital markets. The role of the central bank was re-defined and strengthened in terms of price stability, supervision and regulation. Although there is an increase in financial sector service providers and products, rural households' access to financial services did not improve. To the contrary access to formal financial services is diminishing significantly, hence making poverty reduction initiatives more difficult. This study analyzed constraints to access to rural financial services, examined its impact on rural households' livelihoods, and recommended appropriate financial sector development strategies. The data for the study were collected from various sources - both primary and secondary. Primary data were collected from selected thirteen villages in Babati and government offices in the district through interviews, focus group discussions, questionnaire, and observation. Secondary information was gathered from documentary sources in the form of reports, records and review of literature. A combination of analytical tools was used - qualitative and quantitative. The study observed that history of rural finance in Tanzania is associated with colonialization of Tanganyika. The German colonial administration was the first to introduce establishment of modern commercial banking in the country in 1905 when the Deutsche Ostafrikanische bank opened a branch in Dar es Salaam. The British colonial administration, after the defeat of Germans in World War I, promoted establishment of commercial banks in Tanganyika in order to support commercialization of the economy. Consequently, German banks were replaced and commercial bank branches were established in other parts of the country. The independent government undertook massive re-organization of the financial sector and much attention was put on agricultural credit. Agricultural credit was organized through specialized agricultural credit organizations that corroborated with state owned commercial banks. However, the co-operative movement were assigned important role in credit administration on the ground as they are closer to the beneficiaries. The financial structure after independence up to the 1990s, when reforms were ushered in, is characterized by state owned financial institutions with pervasive interference. Credit was directed on the basis of the government priorities with little regard to credit worthiness analysis. The National Bank of Commerce (NBC) and Co-operative and Rural Development Bank (CRDB) were the dominant banks that implemented the government monetary policy. Emphasis was put on credit and savings mobilization was neglected. The CRDB operated mostly on managing donor funds meant for rural development. Liberalization of the financial sector was introduced through the Banking and Financial Institutions Act (BAFIA) of 1991 to address the weaknesses observed in the financial sector. It was envisaged to improve access to financial services through enhanced competition, increased and diversified financial products and providers, and improved integration of the financial system. However, assessment of the impact of the financial liberalization has mixed results. While there are distinct expansion in financial institutions, products and services; these are more concentrated in urban areas and accessed mostly by wealthy clients. Consequently, rural households' access to finance is diminishing. On the other hand, most financial institutions continue to employ traditional banking approaches - of insistence on collateral, preference for less risky category of clients, bias towards large loans, and bureaucratic procedures in providing loans. Besides, there are limited initiatives in product innovation, design of appropriate delivery mechanisms, and high interest rates spreads that discouraged potentials borrowers and depositors. As a result of poor access to financial services, most households have strengthened self-financing mechanisms through the informal arrangements. Although, the semi-formal - especially member based financial institutions and some Financial NGOs (FiNGOs) are attempting to correct the financial imbalances, their outreach, products and services are still limited. While there are improvement in supervision and regulation of the financial sector, it must be noted that prudential regulation and supervisions as part of the financial infrastructure if not carefully used, will undermine the efficiency of the financial market. The study concludes that rural households need a variety of financial products that include savings facilities, loans, insurance, leasing, and means of transfer payments. The degree of demand for these products is, however, determined by household's level of poverty, household size, level of education and skills, life cycle needs, and local market opportunities. However, financial sector reforms had little impact on households' livelihoods. Its implementation is associated with an increase in inequalities and poverty. Besides, there is a reduced funding as well as investment in agriculture, which forms the key sector of the economy. Consequently, the performance of the agricultural sector has been declining although its contribution to GDP is still significant. Assessing the supply and demand for rural financial services, it is concluded that rural areas are hardly served by banks hence limiting access to financial services. Prior to liberalization, government owned financial institutions provided limited financial services to rural areas organized through co-operatives and specialized credit agencies. CRDB was responsible for organization of credit for farm inputs, while NBC provided crop finance. In addition, CRDB also facilitated rural development programmes through donor funds. With the liberalization of the financial sector - co-operatives have collapsed, development banks are no longer active, and commercial banks have withdrawn from serving rural areas, thus creating a "supply gap" that is being replaced by informal finance. Furthermore, the study observed that demands for financial services is determined by age of the borrower, household size, and distance from a financial institution, the cost of borrowing that include loan transaction costs plus interest rate charged, bank procedures and conditions, policy and regulatory framework and institutional and infrastructural conditions. The study recommends the following: (i) Continued efforts for establishment of supportive macroeconomic and sectoral policies - financial, fiscal, monetary & rural development - and legal and regulatory framework that facilitates the growth of the rural financial markets, (ii) A facilitative intervention by the government in the development of the financial markets that addresses the national poverty reduction development objective through economic growth is required. The desired actions are those that focus on improvement in demand for financial services, reduced bureaucratic banking conditions, reduced transactions costs, improved infrastructure, and reduction of other structural bottlenecks limiting access to financial services, (iii) Development of appropriate financial institutions and products relevant for the rural sector requires government guidance through policy, development of appropriate financial infrastructure (legal, regulation and information), and incentive mechanisms. (iv) Intervention by the government in institutional and infrastructural development is required so as to facilitate the functioning of markets. There must be purposive investment strategy that supports development of the public infrastructure - such as transport and communication, electricity, security system, and research and development. Institutional development - judiciary machinery, credit bureaus, and property rights and business registry are required. Furthermore, training and capacity building so as to change peoples' mindsets concerning loans and savings mobilization, and (v) There is a need for building up a "New Role" for financial institutions. Financial institutions need to revisit their financial terms and conditions in favor of the development of RFMs, especially in terms of bank conditions, interest rate spreads, demand for collateral, and requirements for addressing the needs of the poor and rural population, Furthermore, financial institutions need to become more innovative in developing new products and services, improvement in organization of rural financial institutions, delivery mechanisms, and establishment of the institutional framework for integration of MFIs into the national financial system in the country. The following areas require further studies: (i) development of realistic rural development strategy that covers, among others, the development of the financial markets, (ii) institutionalization of the rural property ownership rights in order to establish how these can be used productively, through say mortgage, collateral, and/or sale for cash income, and (iii) Mechanisms for enforcement of loan repayments in rural areas - especially the lessons from informal operators. Experiences have shown that under informal credit arrangements, there are few default cases as opposed to formal commercial credit practices. / Development Studies / D. Litt. et Phil.

Cooperative learning is a pedagogic approach that is prevalent in all levels of education as it is seen to yield higher learning outcomes than individual learning (Johnson &amp; Johnson, 2009). In the global university, it is believed to have the potential of increasing intercultural contact since students work together in small groups to conduct projects related to their discipline. The assumption is that students will learn the intercultural skills they need for an interconnected world by studying and learning in groups with linguistically and ethnically diverse others (Association of Community Colleges Canada, 2010). Although cooperative learning is based on social interdependence in which group members work together for the mutual benefit of their group, there has been very little research conducted into the relationships that the group members actually have with each other. It is the aim of this study to examine these relationships and find out their impacts on cooperative learning experiences. Drawing upon insights from pragmatism and dialogism, in this thesis, learning is conceptualised as an embodied, socially situated, and relational process. This means that the key to learning is the relationships that learners can construct with others. An integral part of forming relationships is the negotiation of identities in which people see themselves and others as certain kinds of people. In learning in cooperative groups, the ability to negotiate legitimate, competent identities is regarded as essential. For this reason, the study reported in this thesis uses a view of identity as socially constructed as a lens though which to analyse relationships in cooperative learning. The study focuses on the experiences of 12 students participating in group learning projects in first year business courses. Narrative inquiry is the methodology used as it is ideal for highlighting the complexities in human relationships and issues of power. The narratives of four international, four Canadian immigrant, and four Canadian-born students are analysed. A key finding from the analysis is that the relationship students are able to negotiate in cooperative groups and the types of identities they are able to construct with others strongly impacts their learning. There appeared to be a hierarchical order to student identities in groups with Canadian-born students assuming more powerful identities. Frequently these students are results oriented showing only interest in achieving high marks in their group projects. This leads to an absence of emotional connectedness amongst students and a disregard for the process aspect of working together which is core to cooperative learning. The thesis concludes with a discussion of the ways that cooperative learning could be changed to make it more process oriented. Finally, I make recommendations for further research which can build on the findings from this study.

À la suite de la Seconde Guerre mondiale, l’Europe est affaiblie et divisée. Les horreurs de la guerre amènent les Européens à repenser leur cohabitation et l’idée d’une Europe, unie par des liens économiques et politiques forts, germe dans l’esprit des Européens. Ils créent alors la CECA en 1951 puis, sept ans plus tard, la Communauté économique européenne. Puisque cette dernière aura du succès, certains pays européens, dont la Grande-Bretagne, demandent à la rejoindre. La France d’alors, sous la présidence de Charles de Gaulle, s’oppose à cette demande d’adhésion à deux reprises, en 1963 et en 1967. Il faut attendre l’arrivée de Georges Pompidou à l’Élysée pour que Londres intègre la CEE. L’élargissement de la Communauté est un évènement important; il a un impact direct sur le rôle de la France en Europe et dans le monde. Il a également une incidence certaine sur le rôle de l’Europe dans le monde bipolaire de l’époque, ainsi que sur ses relations avec l’allié américain. La presse des pays concernés suivra ces évènements avec intérêt, telle la presse quotidienne française, qui commente abondamment les décisions prises par son gouvernement. Le présent mémoire, qui étudie certains journaux d’importance à la lumière des ouvrages d’érudition et des sources primaires, analyse thématiquement la position de journaux français de diverses tendances politiques sur la politique française au cours des trois demandes. / Following the Second World War, Europe was divided and weak. The horrors of war forced Europeans to rethink how to co-exist and the idea of a united Europe with strong economical and political ties grew among them. The ECSC was created in 1951 and then, seven years later, the European Economic Community. When the latter succeeded, some European countries, like Great Britain, asked to join. France, and its president Charles de Gaulle, objected to the British application on two occasions, in 1963 and in 1967. London had to wait for the arrival of a new French president, Georges Pompidou, to be officially accepted in the EEC. The enlargement of the Community was an important event because it had an impact on France’s role in Europe and in the world. It also influenced Europe’s role in the then bipolar world and on its relations with the United States. The national press of the countries involved covered the events surrounding the enlargement with interest. The French daily press commented on them at length. Using both historical studies and primary sources, this thesis thematically analyzes the views of French newspaper of different political horizons on French policy surrounding the three British applications.
