This thesis explores eating habits among seven second-generation immigrants born, raised and living in Scania, southern Sweden. It does so by using a thematic analysis of data gathered through semi-structured interviews. The theoretical framework combines Douglas’ symbolism, Bandura’s social learning theory and acculturation models. The results show that interviewees maintain memories from childhood and emotions attached to eating habits; parents play an important role in shaping the individuals’ habits as well as their successful assimilation of the majority traditions. Moreover, there is a general preference for social eating rather than eating alone, and a strong connection between traditional food and cultural belonging. Differences in eating habits were recognized as reasons of discrimination and feelings of alienation. However, thanks to their parent’s influence, interviewees negotiate the different cultural realities they live in. The findings contribute to research in the sociology of food and eating and can be employed in policy development.

In this thesis the cultural preservation of the Navajo Nation is analyzed through a multicultural and assimilation framework. The Navajo Nation is a case study in this research. A policy analysis is used in this thesis and analyses policies in three proxy categories of culture: education, land ownership, and self-governance. The main policies analyzed in this thesis are the current (federal) policies regarding education, land ownership, and self-governance. Current means the policies that are in place and in effect today. This thesis also analyses past policies in order to create a foundation. It further analyzes these policies to examine the outcomes and implications of the policies on the cultural preservation of the Navajo Nation. Gerd Baumann’s theories on culture, Kymlicka’s liberal multiculturalism, Margalit and Halbertal’s communitarian multiculturalism, and assimilation are used as the theoretical framework of this thesis. The findings cannot be generalized. Some policies have the outcome that was intended whereas other policies have the opposite outcomes of what was intended in the policy. Thus, multicultural policies do not necessarily have a multicultural outcome, sometimes the outcomes of the policy can have an opposite outcome of what the nature of the policy is.

This study focuses on annual earnings assimilation and the employment probability, described as the assimilation of annual earnings and the extent of which available workers are being used respectively (in this case workers originating from a certain country) of immigrants arriving from former Yugoslavia, i.e. Bosnia-Herzegovina, Serbia and Croatia, to Sweden during the Yugoslav wars occurring in the 1990s. Previous research made on immigrants, and in this case focusing on refugees, brings some empirical standpoints; initial annual earnings of refugees are lower than those of labour-market immigrants and natives, higher education level as well as geographic closeness and cultural similarities between source country and host country makes the transition and assimilation easier for immigrants. Immigrants incur a net-cost on public sector finances during their first years in host country, but that it diminishes as years since migration increases. These longitudinal regressions were made for two different cohorts and genders separately. The cohorts included individuals in ages 20-64 years of age from countries previously being a part of former Yugoslav that arrived in Sweden between the years of 1990 and 1995, and between 1996 and 1999. These cohorts are being studied in three cross-sections, 1990, 1995 and 1999. A brief history of the Yugoslav wars will also be presented in this thesis. Our results show that the refugees from former Yugoslavia had a positive assimilation in to the Swedish labour market, and our results are in line with previous theory regarding labour market assimilation. Moreover, men without university education as well as women with university education assimilate faster in comparison to their corresponding opposites in regards of educational level. However, both genders, regardless of educational level, assimilated. This confirms some of the theory presented in this thesis.

One of the most challenging tasks in the oil industry is the production of reliable reservoir forecast models. Because of different sources of uncertainties the numerical models employed are often only crude approximations of the reality. This problem is tackled by the conditioning of the model with production data through data assimilation. This process is known in the oil industry as history matching. Several recent advances are being used to improve history matching reliability, notably the use of time-lapse seismic data and automated history matching software tools. One of the most promising data assimilation techniques employed in the oil industry is the ensemble Kalman filter (EnKF) because its ability to deal with highly non-linear models, low computational cost and easy computational implementation when compared with other methods. A synthetic reservoir model was used in a history matching study designed to predict the peak production allowing decision makers to properly plan field development actions. If only production data is assimilated, a total of 12 years of historical data is required to properly characterize the production uncertainty and consequently the correct moment to take actions and decommission the field. However if time-lapse seismic data is available this conclusion can be reached 4 years in advance due to the additional fluid displacement information obtained with the seismic data. Production data provides geographically sparse data in contrast with seismic data which are sparse in time. Several types of seismic attributes were tested in this study. Poisson’s ratio proved to be the most sensitive attribute to fluid displacement. In practical applications, however the use of this attribute is usually avoided due to poor quality of the data. Seismic impedance tends to be more reliable. Finally, a new conceptual idea was proposed to obtain time-lapse information for a history matching study. The use of crosswell time-lapse seismic tomography to map velocities in the interwell region was demonstrated as a potential tool to ensure survey reproducibility and low acquisition cost when compared with full scale surface surveys. This approach relies on the higher velocity sensitivity to fluid displacement at higher frequencies. The velocity effects were modeled using the Biot velocity model. This method provided promising results leading to similar RRMS error reductions when compared with conventional history matched surface seismic data.

The Master thesis "Civic Integration of Immigrants in France between 2002-2012" deals with a new integration model of civic integration which the European immigration countries have begun to enforce since the turn of the millennium. An interesting feature of this model is that it is employed by countries whose approch to the integration of immigrants significantly differed till the end of the 20th century. The goal of the thesis is to discover what character shows the civic integration as a new integration model of immigrants in Europe in the integration policies applied in France between 2002-2012. The main hypothesis is based on the theory of the return of assimilation. Its author R. Brubaker claims that in the current integration policies of (not only) European states, the assimilationist tendencies return - however, not in the original concept of assimilation, but in a new transformed concept in between assimilation and multiculturalism. The thesis applies this theory conclusion to the contemporary civic integration policies, so the research verifies its assimilationist character. According to the method specially compiled for this research, the results prove that the integration measures accepted in France between 2002-2012 show a development from a moderate to considerable assimilationist...

The national politics of interwar Poland aimed at the full assimilation of the national minorities, including Ukrainians who lived in the occupied region of Eastern Galicia. This thesis studies the political basis, tools and outcomes of polonization policy during the period between 1918 and 1939 on the territory of Eastern Galicia and its main city Lviv. Deep analysis of Polish and Ukrainian political doctrines, Polish legislation, books, articles and periodical of the interwar period, as well as of modern historiography (both Polish and Ukrainian) resulted in developing of a comprehensive understanding of why the policy of polonization, aimed on population of Eastern Galicia failed to change historical Ukrainian identity. The data gathered in the analysis proves that the Polish government used tremendously rigid, if not brutal, tools of assimilation, and it resulted in rejection of the Polish national identity by Ukrainians. Moreover, confidence in the fact that Ukrainians are nothing more than underdeveloped Poles-to-be rise led to the rise of Ukrainian radical nationalism on the eve of the Second World War.

The thesis deals with the preparation of initial conditions for nume- rical weather prediction in high resolution limited area models. It focuses on the problem of preserving the large-scale part of the global driving model analysis, which can not be determined in sufficient quality in limited-area models. For this purpose, the so-called BlendVar scheme is used. The scheme consists of the appli- cation of the Digital Filter (DF) Blending method, which assures the transmission of a large-scale part of the analysis of the driving model to the limited area model, and of the three-dimensional variational method (3D-Var) at high resolution. The thesis focuses on the appropriate background error specification, which is one of the key components of 3D-Var. Different approaches to modeling of background errors are examined, including the possibility of taking into account the flow- dependent character of background errors. Approaches are also evaluated from the point of view of practical implementation. Study of evolution of background errors during DF Blending and BlendVar assimilation cycles leads to a new pro- posal for the preparation of a background error covariance matrix suitable for the BlendVar assimilation scheme. The use of the new background error covariance matrix gives the required property...
