The theory of redistribution systems is a practical extension of a game theory, which deals with a redistribution within a social system of more than two players with di?erent performances and ability to create coalitions. This thesis is divided into three chapters. The ?rst chapter describes the known knowledge of a game theory. The second chapter deals with the theory of redistribution systems. Using an elementary redistribution system and its generalization group behaviour when dividing a payment, achieved by a collective performance, is described. This part introduces the extension of the redistribution system to a compound redistribution system with a fractal structure. Furthermore the theory of discriminatory equilibrium and the theory of commonly acceptable equilibrium are veri?ed using the elementary redistribution system and utility theory. The third chapter deals with an application to the allocation of funds among faculty departments. A game theory approach was used to reduce the game to a non-cooperative game of two players by using the forming of coalitions. Also the theory of redistribution systems was applied when a reduction was used to create a non-cooperative two-player game. This reduced non-cooperative game between two players was converted to a cooperative play of more than two players by changing the rules of the game and allowing a formation of coalitions. In the practical part both of these approaches are compared with real data and a current state.

Plus de cinquante ans après leur indépendance, la majorité des pays de la région Afrique du Nord et Moyen-Orient (MENA) demeurent tributaire des revenus générés par l'exportation des hydrocarbures. Ces pays peinent à développer leurs économies malgré les grands potentiels (humains et naturels) dont ils disposent. L'indice de développement humain dans beaucoup de pays pétroliers de la région est plus inférieur que dans certains pays de l'Afrique subsaharienne ou de l'Amérique latine. Les gouvernements de ces pays sont confrontés aujourd'hui, plus que jamais, aux problèmes de chômage, de la corruption, de l'économie informelle, etc. L'épuisement certain, dans les quelques années à venir, du pétrole, ainsi que la chute des prix depuis mi 2014, sont les raisons essentielles qui devraient pousser les gouvernements de ces pays à préparer l'après pétrole, à travers la promotion des investissements nationaux et étrangers, le développement des autres secteurs d'activité, hors hydrocarbures, comme l'agriculture, l'industrie et le tourisme. Les mutations que connaît la région MENA, depuis les soulèvements populaires de 2011, ainsi que l'avancée de l'État Islamique, freinent considérablement les réformes économiques entamées dans nombreux pays tels que la Libye, l'Irak (depuis son invasion en 2003) et le Yémen. Les rivalités entre les autres puissances comme l'Iran et l'Arabie Saoudite, ainsi que l'Arabie Saoudite et l'Algérie n'arrangent pas non plus la coopération intra régionale, d'où la nécessité pour les pays arabes de s'allier et de coopérer, en matière économique comme politique, afin de développer l'économie de l'ensemble des pays de la région. / More than fifty years after their independence, most of the countries of Middle East and North Africa (MENA) region are still subject to the revenue generated by the export of hydrocarbons. They have difficulty to develop their economy in spite of their important capacities (natural and human). The IWD in those petroleum countries in this region is lower than some countries in Sub-Saharan Africa and Latin America. Nowadays, Governments are facing to unemployment, corruption, informal economy, etc. And, the clear depletion of oil in the future, as the falling oil prices since 2014, are critical reasons to encourage Governments in a reflexion on the post-oil, through the promoting of national and international investments, the diversification of lines of business, non-hydrocarbons, as agriculture, industry or tourism. Mutations in MENA region, not only popular uprising in 2011 but also the advance of Islamic State, are a brake on economical reforms started in Libya, Iraq (since 2003) and Yemen. The rivalries between Iran and Saudi Arabia, and Algeria and Saudi Arabia damage the intra-regional cooperation. That is why those regional countries have to connect and collaborate, on economical and political subjects, in order to develop the economy of the entire region.

Purpose: The purpose of this was to assess skills and experience in commercial farming among black farmers; identify s kills required in commercial farming among black farmers; and empirically gain an insight of experience and constraints black farmers face in commercial farming. Design/methodology/approach : Qualitative and quantitative data collection methods were used. Qualitatively, 12 participants were interviewed and 41 participants answered a closed-ended questionnaire. The following variables were used to assess black farmers' s kills in commercial farming: skills in farm management principles; skills in decision making science; skills in farm record keeping; skills in farm risk management; skills in creating a competitive advantage for a farm business; skills in farm financial management; and experiences and constraints facing black commercial farmers. Findings: It was found in this study that there is a significant deficiency in black farmer ' skills in commercial farming. The study further found that black farmers require skills in farm management principles, decision making science in farming, farm record keeping, risk management in farming, creating a competitive advantage for a farm business and farm financial management. In terms of their experience from their successes and failures, black farmers perceive that they need to be committed and determined, to have passion, patience and perseverance, and need to work collectively in farming business. Research limitations/implications: A number of participants in both methods of collecting data limited the generalization of results. However, bridging of skills gap among black farmers could improve on their current practice in commercial farming. In their own experiences continuous support from relevant structures could impact positively in their commercial farming. / Thesis (MBA) North-West University, Mafikeng Campus, 2010

Land reform in South Africa is premised on land restitution. land redistribution and security of terlllre as its major components. It has the following objectives amongst others, to address the injustices of racially-based land dispossession; inequitable distribution ofland ownership; need for security of tenure for all: need for sustainable use of land: need [or rapid release of land for development: need to record and register all rights in property: and the need to administer public land in an effective manner. Over two decades of the democratic dispensation, lack of proper funding and capacity by government official to expedite the land reform processes deprives the rural communities like the Morebene community the enjoyment of their land rights and proper redress after devastating land dispossession. The research has managed to establish the serious pain and suffering that has been brought by incompetent implementation of six phases of land restitution process by Limpopo RLCC to the commuillty of Morebeoe. Lack of capacity to implement land restitution processes has been found to have been a major setback to lhe Morebene communjty to an extent that their restitution processes were abandoned by the Limpopo RLCC at project execution stage. The community composed of nearly 81% of rhe youth and middle aged people bas been left without jobs and no property rights and development all of which are caused by the lack of expertise from the oHicials of the RLCC. No restitution grants and development gTants were granted to the community and no formal or informal training let alone workshops held in relation to the government"s expectations from the land reform policies and legislation. / Development Studies / M.A. (Development Studies)

Die vorliegende Arbeit setzt sich mit der öffentlichen Kinderbetreuung in Deutschland auseinander. Im Fokus stehen dabei die Determinanten der regional unterschiedlichen Kindergartengebühren, die Nachfrage nach öffentlicher Kinderbetreuung einschließlich der daraus resultierenden Verteilungswirkungen, die kommunale Effizienz in der Bereitstellung sowie die Anpassbarkeit der kommunalen Ausgaben an sich ändernde Nachfragemuster. Ein besonderes Augenmerk wird auf die Bereitstellung öffentlicher Kindergärtenplätze für Kinder im Alter von vier Jahren bis zum Schuleintritt gelegt. Zum Zeitpunkt der Datenerfassung war nur für diese Gruppe ein rechtlicher Betreuungsrahmen vorgegeben, der verschiedene Regionen miteinander vergleichbar macht und somit eine wesentliche Grundlage für die vorgenommene empirische Analyse darstellt. Hinsichtlich der Gebührenunterschiede zeigt sich, dass Städte die Kinderbetreuungsgebühren als Instrument für einen aktiven Standortwettbewerb nutzen. In Städten mit einem hohen Anteil junger Bevölkerung sind die Gebühren geringer als in anderen Städten. Zugleich verlangen Städte, die eine höhere Betreuungsqualität bereitstellen, geringere Gebühren als Städte mit einer geringeren Betreuungsqualität. Aufgrund einkommensabhängiger Gebühren resultieren aus der Nachfrage nach öffentlicher Kinderbetreuung Einkommensumverteilungseffekte. Nach der ökonomischen Theorie sollte die Nachfrage nach Kinderbetreuung im Einkommen der Eltern steigen und im Preis der Betreuung fallen. Bei einer Einkommensänderung wirken demnach zwei gegenläufige Effekte gleichzeitig auf die Nachfrage: Eine höhere Zahlungsbereitschaft steht einem höheren Preis gegenüber. Die empirische Analyse zeigt, dass in Deutschland der negative Preiseffekt den positiven Einkommenseffekt der Nachfrage überwiegt. Die Nachfrage nach öffentlicher Kinderbetreuung ist somit im Einkommen der Eltern rückläufig, wodurch es zu einer Einkommensumverteilung von einkommensstärkeren zu einkommensschwächeren Haushalten kommt. Unterschiedliche Gebühren in den Kommunen können auch auf eine unterschiedliche Effizienz in der Bereitstellung öffentlicher Kinderbetreuung zurückzuführen sein. Die Ergebnisse einer empirischen Effizienzanalyse zeigen, dass die betrachteten Kommunen unterschiedlich gut in der Lage sind, eine bestimmte Betreuungskapazität mit geringstmöglichem Mitteleinsatz zu erreichen. Die Median-Kommune gibt etwa 25 % mehr aus, als es für das Betreuungsangebot erforderlich wäre. Dieses Ergebnis bleibt erhalten, wenn für die Ergebnisse der betreuten Kinder in ihren Schuleingangstests kontrolliert wird. Bestimmte Einflussfaktoren bedingen die Ineffizienzen vor Ort. Beispielsweise sind die Kommunen mit einem ehrenamtlichen Bürgermeister bzw. solche Kommunen mit geringer Einwohnerzahl vergleichsweise ineffizient. Gleiches gilt auch für Kommunen mit einem hohen Anteil der über-65-Jährigen Bevölkerungsgruppe. Vor dem Hintergrund des demografischen Wandels muss auch die Anpassbarkeit kommunaler Ausgaben für Kinderbetreuung an sich ändernde Nachfragemuster in den Blick genommen werden. Es wird gezeigt, dass sich die Ausgaben für Kinderbetreuung proportional an die Nutzerzahl anpassen lassen, ohne dass dabei die Qualität der Leistungserstellung beeinträchtigt werden muss. Die Anpassungen müssen jedoch diskretionär und regelmäßig erfolgen, da andernfalls ein ineffizientes Betreuungsangebot zu überhöhten Kosten unterhalten wird.

This study has centered on the proposal for decreasing the entrance rate in order to create more jobs and integrate the increasing asylum seekers in the Swedish society. Based on a discourse analysis on the parliamentary debates “The road to the labor market” and “Integration”, this thesis examines the discourses around ‘justice’. By applying Nancy Frasers theoretical framework of justice, the arguments were analyzed in order to understand if the constructed problems were built on the dimension of recognition or redistribution and to investigate if the solutions were based on an affirmative or transformative strategy. The analysis shows that the primary justice discourse in the debate of labor and integration is the distribution dimension. The injustices that are presented in these debates are concerned with maldistribution. Affirmative strategies are mostly suggested for solutions which indicates that the politicians in the Swedish parliament have an urge to solve problems in the present instead of focusing on the future and solving the underlying structure.

Water-induced soil erosion and shallow landslides interact with each other and need to be studied in an integrated approach to understand hillslope sediment yields. The principal aim of this thesis was to study and model soil erosion and shallow landslides in an integrated way. The thesis presents results from laboratory and catchment-scale studies and modelling. A laboratory flume under a rainfall simulator was used for shallow landslide and soil erosion experiments using sandy and silty loess soils. In the experiments, landslide initiation, retrogressions and slip surface depths were measured and monitored directly or by using video camera recordings. Sediment and runoff were collected from the flume outlet every minute during landslides and every 10 minutes before and after landslides. Changes in the soil slope, after landslides, were recorded. Initially, six experiments including two repetitions were conducted using sandy soils at a 30º and 10º compound slope configuration, but with different soil profile depths. The experimental results showed that total and landslide-driven sediment yields were affected by the original soil profile depth; the greater the depth, the higher the sediment yield. Later, twelve other experiments were conducted on different slopes using silty loess soils. The experimental observations were used to validate an integrated modelling approach which includes WEPP for runoff and soil erosion modelling, a slope stability model for simulating shallow landslides, and a simple soil redistribution model for runout distance prediction. The model predictions were in good alignment with the observations. In all (sandy and silty loess) experiments, peak sediment discharges were related to the landslide events, proximity to the outlet and landslide volume. The post-failure soil erosion rate decreased as a function of changes in the slope profile. The GeoWEPP-SLIP modelling approach was proposed for catchment-scale modelling. The approach simulates soil erosion using the Hillslope and Flowpath methods in WEPP, predicts shallow landslides using a slope stability model coupled with the WEPP’s hillslope hydrology and finally uses a simple rule-based soil redistribution model to predict runout distance and post-failure topography. A case study application of the model to the Bowenvale research catchment (300 ha) showed that the model predictions were in good agreement with the observed values. However, the Hillslope method over-predicted the outlet sediment yield due to the computational weighting involved in the method. The Hillslope method predicted consistent values of sediment yield and soil erosion regardless to the changes in topography and land-cover in the post-failure scenarios. The Flowpath method, on the other hand, predicted higher values of sediment yield in the post-failure vegetation removal scenario. The effects of DEM resolution on the approach were evaluated using four different resolutions. Statistical analyses for all methods and resolutions were performed by comparing the predicted versus measured runoff and sediment yield from the catchment outlet and the spatial distribution of shallow landslides. Results showed that changes in resolution did not significantly alter the sediment yield and runoff between the pre- and post-failure scenarios at the catchment outlet using the Hillslope method. However, the Flowpath method predicted higher hillslope sediment yields at a coarser resolution level. Similarly, larger landslide areas and volumes were predicted for coarser resolutions whereas deposition volume decreased with the increase in grid-cell size due to changes in slope and flowpath distributions. The research conducted in the laboratory and catchment presented in this thesis helped understand the interactions between shallow landslides and soil erosion in an integrated approach.

In this study, a total of twelve beams continuous over two spans of 2,800 mm each were constructed and tested to failure. The beams were divided into two series. Series 1 included six T-beams under symmetrical loading, while Series 2 dealt with six rectangular beams under unsymmetrical loading conditions. In Series 1, the test variables included material type, assumed percentage of moment redistribution, spacing of lateral reinforcement in flange, arrangement of shear reinforcement, and serviceability requirements. In Series 2, three different loading cases were considered, I) loading both spans equally, II) loading both spans maintaining a load ratio of 1.5 and III) loading one span only. Under the loading case II, the parameters of reinforcing material type, assumed percentage of moment redistribution and serviceability requirements were investigated. The test results of both series showed that moment redistribution from the hogging to the sagging moment region took place in GFRP-RC beams which were designed for an assumed percentage of moment redistribution. In Series 1, the decrease of the stirrups spacing from 0.24d to 0.18d enhanced the moment redistribution percentage. Also, decreasing the spacing of lateral reinforcement in the flange from 450 to 150 mm improved the moment redistribution through enhancing the stiffness of the sagging moment region. In Series 2, the unsymmetrical loading conditions (loading case II and III) reduced the moment redistribution by reducing flexural stiffness in the heavily loaded span due to extensive cracking. Regarding serviceability in both series, the GFRP-RC beam designed for the same service moment calculated from the reference steel-RC beam, was able to meet the serviceability requirements for most types of the structural applications. / February 2017

This work analyzes the redistribution of the pension insurance for people with different income levels.

This thesis is focused on questions of state redistribution and income inequality in the Czech republic. It explains the main ideas of state redistribution, income inequality and relation between them. It anlyzes the particular instruments of state redistribution such as tax systems and systems of social transfers which the government uses to achiave more equal distribution of incomes in society. The object of the thesis is to find out how the particular instruments contribute to filling the essentials goal - lower the income inequality in society. It is based on the data from years 2006 until 2008 from the statistics of household accounts published on the web site of the Czech statistical office. Finally, it is devoted to the trends of state redistribution and income inequality in OECD countries.
