Storlommens (Gavia arctica) häckningsframgång relaterad till vattenkvalitet

This work investigates the breeding success of the Black-throated Diver, Gavia arctica, related to the water quality in three lakes located in the Vallentuna area, north of Stockholm, Sweden.For more than 30 years, I have studied the bird life around these three and other nearby lakes, and noticed that the Black-throated Diver breeds in some lakes, but not in others.The results confirm that the deep and clear lakes Tärnan and Stora Harsjön have good water quality regarding pH, alkalinity, aluminium and Secchi disk values. As expected, the Black-throated Diver shows breeding success in those two lakes, but does not breed in the shallow and eutrophic lake Mysslingen.

Actitudes hacia la lengua náhuatl : Un estudio sociolingüístico con jóvenes de la Ciudad deMéxico.

Nahuatl is one of the indigenous languages in Mexico that is at risk of falling out of use. The research in the last years have showed that this occurs due to the low amount of Nahuatl speakers and the social stigma and discrimination towards the indigenous peoples, among other factors.The studies of language attitudes are relevant when making attempts to revitalize a language. As Mexico City authorities have considered to implement a revitalization project, we wanted to approach the real situation of Nahuatl in that city. Our purpose was to measure the attitudes of young people towards this language. By using a direct method –a questionnaire- we asked two groups of students if they agreed or disagreed with some items about Nahuatl and its speakers. One group had contact with Nahuatl speakers and but not the other one. We compared the results and they showed that the students who have contact with Nahuatl have more positive attitudes than those who don’t have any contact with it. This study also revealed that the reason why the first group showed positive attitudes was solidarity with the Nahuatl speakers. However, the both groups considered that speaking or learning Nahuatl cannot contribute to raise their status in the Mexican society.

"Ungerska för rötternas skull" : Språkval och identitet bland andragenerationens ungrare i Sverige och Finland

This thesis is a comparative sociolinguistic study which describes and compares language choice among people with Hungarian background in Sweden and Finland and studies their views on the importance of the Hungarian language and Hungarian cultural heritage for identity. The future prospects of language maintenance and language shift and differences between the Swedish-Hungarians and the Finnish-Hungarians are discussed. A survey was completed among 50 Swedish-Hungarian informants and 38 Finnish-Hungarian informants during 2006. The survey was supplemented by in-depth interviews with 15 informants during 2007. The majority language, either Swedish or Finnish, is much more active in the second-generation Hungarians’ lives than Hungarian is. Hungarian is mostly used in the domain of family relations. The language choices made today are dependent on the informant’s situation during childhood, particularly the parents’ usage of the language and the ability to learn and use Hungarian, chiefly gained through contact with the parents’ mother country and other Hungarian speakers. For some informants, having Hungarian roots forms the sole foundation for belonging, while for others it is this heritage combined with the culture, the ability to use the language or specific character traits. The Hungarian background is most often seen as a treasure offering diversity in life. Finnish-Hungarians are generally more positive about their Hungarian background, have better competence in the language and a greater awareness of the culture than Swedish-Hungarians. The Hungarian language plays a central though often symbolic role. The most important conditions for minority language preservation are language competence together with the desire and opportunity to use it; whereof the largest deficit among second-generation Hungarians is knowledge of the Hungarian language. Only one-fourth of the informants have all of the conditions necessary to be able to maintain the language, which means that Hungarian is an endangered minority language in Sweden and Finland.
