Since the fate of the Syrian/Assyrian minority that has fled Turkey has not received much attention in research, this thesis is made to recognize the group and their experiences as refugees, Christians, and citizens in their old and new countries of Turkey and Sweden. When talking about dual citizenship, in terms of previous research, researchers often argue about how migrants prefer to keep their former citizenship when moving to another country. According to scholars and policymakers, dual citizenship is a benefit since it, for instance, helps immigrants to naturalize into their country of settlement. However, this is not always the case. By interviewing nine Syrians/Assyrians from Turkey, who either hold dual citizenship (Swedish and Turkish citizenship) or only Swedish citizenship (former Turkish citizens), this thesis will focus on how the minority thinks, feels, reasons, and argues about dual citizenship. Because of a history filled with oppression, discrimination, violence, and death (the Syrian/Assyrian genocide in 1915) in Turkey, many Syrians/Assyrians did not want to keep the bond to their country of origin when migrating to Sweden. In the sense of security and safety, belonging, naturalization and integration, and loyalty, this study will focus on what dual citizenship means for the Syrian/Assyrian participants who came to Sweden in the 1970s and if they make use of the possibility to hold more than one citizenship. The main finding is that the minority feels safe and at home in Sweden and not in Turkey. Because of their lack of protection and rights as Christians in their country of origin, Sweden is, as they call it, their new home. Even if some of them hold dual citizenship, while others only have Swedish citizenship, the majority of the Syrian/Assyrian people do not feel any sense of attachment, feeling, or loyalty toward Turkey today. However, there are exceptions. By holding dual citizenship, those Syrians/Assyrians who misses the food, the climate, or the culture can visit their country of origin, whenever they want to, as citizens.

The relationships were analyzed by a dialectical perspective of individual-society. From the concerns: 1. What conceptions these students have about the human being? 2. What types of knowledge helps them form these conceptions? 3. How these knowledges relate with the world views these students carry? Two data collection instruments were developed (questionnaire and interview) in order to apprehend the relationships between the knowledge about the human being and the world views of the students. 55 students of three different classes of a public state university answered the questionnaire and four of them the interview. The philosophical fundaments that formed the undergraduates’ world views were: idealism, materialism, transcendental conceptions, ontology, epistemology, abstract subject, concrete subject, formal logic and dialectical logic. The concepts of class and praxis were used to build the world views of the students, having the same theoretical reference used in this research: dialectical historical materialism. Thus, by this reference, the object’s multiple contradictory determinations were used to analyze the dialectical relations present in the world views of the students, and they were: subject x object; objectification x appropriation; teleology x causality; humanization x alienation. The undergraduates, under the infl... (Complete abstract click electronic access below) / Mestre

PAPER The possibilities of naturalization of rare and vanishing plants’ species are surveyed in master’s study The subject of research - The botanical gardens of Liskiava with the rare and vanishing plants’ species cultured and naturalized there. Objective of the research – Naturalized species of the plants: Turk’s-cap (Lilium martagon), medicinal angelica (Angelica archangelica), perennial satinflower (Lunaria rediviva), and ivy bedstraw (Hedera helix). Also the naturalization in site of rare plants is observed and estimated. Methods of study – Some studied plants were brought from their natural vegetation places, digging out it with the thickness of soil, some of then were sown from seeds: macro bloom finger-flower (Digitalis grandiflora), meadowy salvia (Salvia pratensis). The naturalization of these plants and capability to proliferate is also observed. Ecologist of Dzukija National park, Henrikas Gudavicius conduced to pursue the observation and researches, also rendered comprehensive information about the botanical gardens of Liskiava. Such possibilities of naturalization of rare and vanishing plants’ species were no studied in Lithuania. The conclusion could be done under the results of research: rare plants can be naturalized, just the proper place must be chosen and the observation is necessary during the first year. Keywords: National park of Dzukija, The botanical gardens of Liskiava, rare and vanishing plants’ species, naturalization.

À la croisée de l’histoire coloniale et de l’histoire de l’immigration en France, cette thèse se propose d’aborder sous un angle neuf le rôle des Italiens dans la colonisation et le peuplement des villes du littoral oriental de l’Algérie à travers le cas de Bône (Annaba). Elle s’appuie sur un corpus de sources récoltées en France (Paris, Aix-en-Provence, Toulon, Marseille), en Italie (Rome, Pouilles, Sardaigne) et en Algérie (Annaba, Constantine). Un premier axe est consacré à l’étude des politiques migratoires mises en place des deux côtés de la Méditerranée au cours du XIXe siècle pour réguler et contrôler les circulations croissantes entre l’Italie et l’Algérie. Un second s’articule autour des modalités d’installation des Italiens à Bône. Par le biais d’une étude socio-quantitative, les spécificités de l’installation et de l’intégration des étrangers sont étudiées dans un cadre urbain et colonial. Le troisième volet porte sur la place des Italiens dans la société coloniale algérienne de l’entre-deux-guerres. Il permet de resituer l’Algérie dans la politique africaine de l’Italie libérale et fasciste, et plus largement dans les rapports franco-italiens au Maghreb. / At the cross-road of the colonial history and immigration history in France, this PHD thesis proposes to address under a new angle the role of the Italians in the colonisation and settlement of the cities of Algerian western coastline, through the case of Annaba. It is based on a corpus of sources gathered in France (Paris, Aix-en-Provence, Toulon, Marseille), Italy (Rome, Puglia, Sardinia) and Algeria (Annaba, Constantine). A first axis is dedicated to the study of migration policies adopted in both sides of the Mediterranean Sea during the 19th century, which aimed at regulating and controlling the growing circulation between Italy and Algeria. The second axis deals with the modalities of settlement of Italians in Annaba. Through a socio-quantitative study, the specificities of the settlement and integration of foreigners are studied from an urban and colonial perspective. The third axis addresses the status of the Italians in the Algerian colonial society of the inter-war period. It enables to place back Algeria in the African policy of the liberal and fascist Italy, and furthermore in the relationships between Italy and France in Maghreb.

This concern is especially valid in freshwater ecosystems due to their high biodiversity and the highest rates of extinction, compared with terrestrial and marine ecosystems. The increasing habitat complexity provided by the presence of macrophytes may partially explain the high diversity of aquatic ecosystems. However, depending on the density and other particular characteristics of these plant, the diversity may be negatively affected. In this context, Urochloa subquadripara, a species native to Africa, is an aquatic macrophyte weed occurring in various natural and artificial aquatic ecosystems in America. In a small scale, the occurrence of this exotic species increases with reducing natives species richness; however, in a large scale U. subquadripara invades sites with more richness of native species. This controversy is typical of observational studies in invasion biology and it demand experiments to test effects of abiotic and biotic resistance on the invasive potential of this exotic. Accordingly, two experiments were conducted in order to test the following hypotheses: (i) the regeneration and colonization of U. subquadripara decreases with increasing time of exposure to dry, (ii) fragments of the apical part of this species, when compared with those of the basal part, have higher viability and colonization potential (first experiment) and (iii) the invasiveness of aquatic environments by U. subquadripara is negatively influenced by the richness and abundance of native species (second experiment). Our results supported all of our hypotheses: U. subquadripara showed high resistance to desiccation, and the fragments of the apical part were those which had higher viability and colonization potential. In addition, both richness and abundance of native species affected negatively the invasive potential of this exotic macrophyte. The second experiment demonstrated that the effect of richness and abundance limited the development of U. subquadripara, although such effect was not sufficient to prevent the invasion of macrophyte communities by this species. Based on these results, it appears that the population growth of U. subquadripara is greater in disturbed sites, mainly those affected by drought, which in general, have lower abundance and diversity of native species. / Espécies exóticas representam fortes ameaças à biodiversidade. Essa preocupação é especialmente válida em ecossistemas aquáticos continentais em função da elevada biodiversidade e das maiores taxas de extinção, quando comparados com ecossistemas terrestres e marinhos. O aumento da complexidade dos habitats promovido pela presença de macrófitas aquáticas pode explicar em parte a elevada diversidade dos ecossistemas aquáticos. No entanto, dependendo das densidades e de outras características espécies-específicas dessas plantas, a diversidade pode ser negativamente afetada. Nesse contexto, Urochloa subquadripara, espécie nativa da África, é uma macrófita aquática infestante de vários ecossistemas aquáticos naturais e artificiais na América. Em pequena escala espacial, a ocorrência dessa exótica aumenta com a redução do número de espécies nativas, já em grande escala U. subquadripara invade locais com maior riqueza de espécies nativas. Essa controvérsia é típica de estudos observacionais em biologia de invasões sendo necessária a realização de experimentos para testar efeitos da resistência abiótica e biótica sobre o potencial invasor de exóticas. Nesse sentido, foram realizados dois experimentos, com o objetivo de testar as seguintes hipóteses: (i) a regeneração e colonização de U. subquadripara diminui com o aumento do tempo de exposição a seca; (ii) os fragmentos da parte apical dessa espécie, quando comparados com aqueles da parte basal, apresentam maior viabilidade e potencial de colonização (primeiro experimento) e (iii) a invasibilidade de ambientes aquáticos por U. subquadripara é influenciada negativamente pela riqueza e abundância de espécies nativas (segundo experimento). De modo geral, todas as hipóteses foram aceitas: U. subquadripara apresentou alta resistência a dessecação, sendo que os fragmentos da parte apical foram os que apresentaram maior viabilidade e potencial de colonização e tanto a riqueza como a abundância de espécies afetaram negativamente o potencial invasor dessa exótica. Esse último experimento demonstrou que, apesar de limitar o desenvolvimento de U. subquadripara, o efeito da riqueza e abundância de nativas não é suficiente para impedir a invasão de comunidades de macrófitas por essa espécie. Com base nesses resultados, infere-se que o crescimento populacional de U. subquadripara é maior em locais perturbados, principalmente por distúrbios como a seca que, em geral, também apresentam menor abundância e diversidade de espécies nativas.

Thesis (PhD)--Stellenbosch University, 2010. / ENGLISH ABSTRACT: Biological invasions are a growing threat to biodiversity, trade and agriculture in South Africa. Though alien reptiles and amphibians (herpetofauna) are not currently a major issue, escalating problems worldwide and increased trade in South Africa suggest a possible increase in future problems. In this thesis I explore practical measures for risk assessment implementable under national legislation. I began by documenting record-keeping and legislative differences between provinces in South Africa. This revealed some serious deficiencies, complicating attempts to compile accurate inventories and discern import trends. International trade data, however, revealed an exponential increase in the number of imports to South Africa over the last 30 years. Characterising the abundance of species in this trade is important as species introduced in large numbers pose a higher establishment risk. In South Africa, I found a tendency for venomous and expensive species to be traded in low numbers, whereas species that are easy to breed and handle, or that are colourful or patterned are traded in higher numbers. Unlike South Africa, California and Florida have had a large number of well-documented herpetofaunal introductions. These introductions were used to verify the role of several key predictors in species establishment. I first evaluated the role of each variable separately. I examined different approaches for bioclimatic modelling, the predictive power of different sources of distribution data, and methods of assigning a climate-match score. I also present the first test of Darwin’s naturalization hypothesis for land vertebrates using two new phylogenies inferred for native and introduced reptiles in California and Florida. I then used boosted regression trees (BRT) to infer the relative contribution of each factor to species establishment success. Results from the BRTs were incorporated into a user-friendly spreadsheet model for use by assessors inexperienced in complex modelling techniques. Introduction effort was found to be the strongest contributor to establishment success. Furthermore, species with short juvenile periods were more likely to establish than species that started breeding later, as were species with more distant relatives in regional biotas. Average climate match and life form were also important. Of the herpetofaunal groups, frogs and lizards were most likely to establish, while snakes and turtles established at much lower rates, though analysis of all recorded herpetofaunal introductions shows slightly different patterns. Predictions made by the BRT model to independent data were relatively poor, though this is unlikely to be unique to this study and can be partially explained by missing data. Though numerous uncertainties remain in this field, many can be lessened by applying case by case rules rather than generalising across all herpetofaunal groups. The purpose for import and potential trade volume of a species will influence the threat it poses. Considering this in conjunction with a species’ environmental tolerances and previous success of species with similar life histories, should provide a reasonable and defendable estimate of establishment risk. Finally, a brief summary of the potential impacts of introduced alien herpetofauna is provided in the thesis. / AFRIKAANSE OPSOMMING: Indringer spesies hou ‘n al groter bedreiging in vir die biodiversiteit, handel en landbou van Suid- Afrika. Alhoewel uitheemse reptiele en amfibieërs (herpetofauna) tans nie ‘n groot bedreiging in Suid-Afrika is nie, dui groeiende probleme wêreldwyd asook 'n toename in plaaslike handel op moontlike toekomstige probleme. In hierdie tesis, ondersoek ek praktiese metodes vir risikobepaling wat onder nasionale wetgewing toegepas kan word. Ek begin deur die verskille in stoor van rekords en wetgewing tussen provinsies te dokumenteer. Hierdie proses het ernstige tekortkominge uitgewys, wat pogings om akkurate inventarisse saam te stel en invoertendense te bepaal, bemoeilik. Internasionale handelsdata het egter getoon dat daar ‘n eksponensiële toename in die hoeveelheid invoere na Suid-Afrika oor die laaste 30 jaar was. Die hoeveelheid spesies in hierdie handel is belangrik omdat spesies wat in groot hoeveelhede ingevoer word, ‘n hoër vestigingsrisiko het. In Suid-Afrika is ‘n tendens gevind vir handel in giftige en duur spesies teen lae hoeveelhede, terwyl spesies wat maklik teel, maklik hanteer kan word en kleurvol is of mooi patrone het, in groter hoeveelhede mee handel gedryf word. Kalifornië and Florida, in teenstelling met Suid-Afrika, het ‘n hoë aantal goed-gedokumenteerde gevalle van herpetofauna wat in die natuur vrygestel is. Hierdie introduksies was gebruik om die rol van verskeie belangrike faktore in die vestiging van populasies te bepaal. Eerstens het ek die rol van elke faktor apart ondersoek. Ek het verskillende benaderinge vir bioklimatiese model-bou ondersoek, die akuraatheid van verskillende bronne van distribusiedata getoets en drie metodes om ‘n “climate match score” te bereken, voorgestel. Ek bied ook die eerste toets van Darwin se naturalisasie-hipotese vir landwerveldiere aan, deur gebruik te maak van twee nuwe filogenieë wat ek gebou het vir inheemse en ingevoerde reptiele in Kalifornië en Florida. Ek het verder gebruik gemaak van “boosted regression trees” (BRT) om die relatiewe bydrae van elke faktor tot die vestigings-potensiaal van spesies te bepaal. Resultate van hierdie BRTs was ingekorporeerd in ‘n gebruikersvriendelike ontledingstaat wat deur bestuurders, onervare in komplekse modelboutegnieke, gebruik kan word. Invoer-hoeveelheid was die faktor wat die sterktste bygedra het tot suksesvolle vestiging. Verder is spesies met kort jeugperiodes en dié met verlangse familie in streeks-biotas, meer geskik om suksesvol te vestig. Gemiddelde klimaatooreenstemming en lewensvorm was ook belangrik. Paddas en akkedisse was die mees waarskynlikste van die herpetofauna groepe om populasies te vestig, terwyl slange en skilpaaie teen laer tempo’s populasies gevestig het, alhoewel analise van alle gedokumenteerde gevalle van herpetofauna-invoerings wêreldwyd effens verskillende tendense toon. Voorspellings wat deur die BRT-model vir onafhangklike data gemaak is was redelik swak, alhoewel hierdie resultaat onwaarskynlik nie uniek aan die studie is nie, en word gedeeltelik verduidelik deur die gebrek aan data. Alhoewel talle onsekerhede steeds bestaan, kan dié verminder word deur geval-tot-geval reëls toe te pas eerder as om vir herpetofauna as ‘n groep te veralgemeen. Die doel van invoer en potensiële handel-volumes van ‘n spesie, sal die bedreiging wat die spesie toon, bepaal. Hierdie faktore moet saam met omgewingstoleransie en voorafgaande sukses van spesies met soortgelyke lewenswyses oorweeg word, om ‘n aanvaarbare en verdedigbare beraming van vestigingsrisiko te gee. Laastens, word ‘n kort opsomming van die effekte wat uitheemse herpetofauna mag hê, verskaf.
