The box must contain a summary in a maximum of 1,700 characters, spaces included. The fabrication of a CuInSe2 thin film solar cell from an electrodeposited precursor stack consisting of indium selenide and copper selenide layers is demonstrated. A best conversion efficiency of 5.5% was achieved, a higher efficiency than previously reported in literature. The thesis focuses on three main parts: (i) electrochemistry of indium selenide: The incorporation of indium in the deposit requires the presence of selenium species. The obtained film consists of both amorphous In2Se3 and elemental Se. The Se/In ratio depends on the applied potential, although the deposition is mass transport controlled limited by the selenium ion concentration. The potential controls the balance of reduction kinetics between the In2Se3 and elemental Se and both compete for the same intermediate selenium species. (ii) phase reactions during annealing: The small interface area between the electrodeposited indium selenide and the copper selenide layer slows down the interdiffusion during the annealing process. Therefore the temperature required to react the precursor is higher than reported for similar stacks in literature. Copper selenide is retained at the surface for a longer time during the annealing process, where it undergoes the transitions CuSe2 => CuSe => Cu2Se. (iii) loss mechanisms in the solar cell: The highest solar cell conversion efficiency was obtained from a stoichiometric precursor compromising the advantages and disadvantages of Cu-poor and Cu-rich growth. The Cu-poor grown absorber showed a reverse pn-junction at the backside due to an incomplete reaction of the stack. The efficiency of the Cu-rich grown solar cell was limited by high interface recombination. [less ▲]

Résumé : Cette intervention propose d’étudier le DVD de musique metal en tant que dispositif de médiation. L’approche communicationnelle permet d’analyser les modalités d’instauration du sentiment d’« être ensemble », si cher aux fans de metal et ce même lorsqu’on regarde un DVD seul, dans son salon. Cette médiation passe essentiellement par trois modalités, qui se construisent aux niveaux de l’énonciation, de la textualité et des représentations véhiculées par le film. Ainsi, quand Metallica, Iron Maiden ou Mötorhead fondent la relation au spectateur sur l’intimité dévoilée de ses membres (avec des procédés filmiques proches de la téléréalité), Slipknot ou Down préfèrent placer le spectateur en immersion dans l’ambiance (et l’inconfort) du concert, tout en jouant sur les codes et les représentations les plus « rebelles » du metal...

Two studies are presented exploring whether performance on assessments of working memory (WM) and vocabulary is affected by the experience with the test language and/or the linguistic and cultural status of the child. Forty 7-year-old Portuguese-speaking immigrant children growing up in Luxembourg were assessed on a range of L1 and L2 vocabulary measures and verbal WM tests. Their data was compared to monolingual speakers of Luxembourgish and Portuguese from different socioeconomic background (SES) groups. Results showed that WM is highly associated with vocabulary in both native and foreign languages. Furthermore, the study indicates that WM tests are relatively independent of SES, test language, and immigrant/language status. In contrast, results on the vocabulary measures have shown that bilingual immigrant children perform equally well to monolinguals if their combined vocabulary across languages is considered but lack behind their monolingual peers in terms of conceptual development. The data suggests that bilingual immigrants’ poor conceptual knowledge is not simply a reflection of lower SES but instead seems to be a direct consequence of growing up as an immigrant in a multilingual environment. The results of this study have important practical utility especially in relation to improving the range of culture-fair assessment tools that can be used with minority language children. As WM measures are highly associated with children’s language learning and are relatively independent of test language, language status, and SES, these tests might provide valuable tools for distinguishing between language impairments of a cognitive origin and language differences related to the environmental context of growing up as an immigrant with several languages. This distinction is crucial in order to avoid erroneous diagnostics and provide appropriate remediational support that help immigrant children overcome their langue differences in order to improve their chances of accessing the same opportunities and resources as their majority culture peers.

“Cultural awareness,” as a quick Internet search will show, is a widely used phrase and consequently has no single precise meaning. It is used to refer to awareness of diversity within a society and among societies. It is often associated with “training,” involving specific activities which draw attention to diversity and encourage and deliberately develop positive attitudes and understanding. Such training is directed at adults in their professional and working lives. It is linked through this to “intercultural competence” which is based in part on heightened cultural awareness and which is itself fundamental to “intercultural communication.” This field of activity and study is well enough established to have spawned “handbooks” (e.g., Straub, Weidemann, & Weidemann, 2007; Deardorff, 2009) and many textbooks (e.g., Holliday, Hyde, & Kullman, 2004; Jandt, 2004; Chen & Starosta, 2005).

The idea that the modern mathematics can help pupil to become more intelligent or rational as the future citizens, was initiated in the United States after the WWII and accelerated after the launch of Sputnik by the USSR. As a part of martial plan, the United States introduced this idea in Europe through the so-called Royaumont Seminar in 1959. The seminar with the title “New thinking in school mathematics” was organized by the Organisation for European Economic Co-operation (OEEC) and chaired by the American mathematician Dr. Marshall Stone in Royaumont Abbey in Paris. This seminar recommended its member countries to proceed with a reform in their mathematics teaching. Dr. Stone expressed the need for this reform “deep and urgent” (OEEC, 1961, p. 29). Luxembourg was also one of the first nations to participate in these international curricular activities including the Royaumont Seminar (OECD, 1961, p. 215). The development of maths and sciences education became an issue for the country to such an extent that Pierre Frieden, the prime minister of Luxembourg in 1958, proclaimed: “Those, who have the best scientists will win the Cold War … [and] the economic war!” (LW February 27, 1958, p. 3), thus underscoring the need for Luxembourg’s to participate in the reform movement. This paper is part of a research project that studies how New Math was adapted for Luxembourgish primary schools. It works to reveal how a ‘globally’-disseminated idea about how mathematics relates to the ideology of the rational and critical citizen has been implemented in Luxembourg by translating it into its cultural idiosyncrasy. Many Luxembourgian mathematicians attempted to adapt conceptions of the new mathematics for the elementary levels during the 1960s and 1970s. Alongside, these mathematicians were also active in participating and even hosting conferences focusing on the subject of New Maths reform in that era. However, despite all these efforts, the new mathematics officially entered Luxembourg’s primary school textbooks twenty years after the Royaumont seminar. The research data is drawn from relevant archival records including reports, correspondences, teachers’ journals, local newspaper articles, texts of laws, non-official and official relevant school-books of the era in Luxembourg. In addition, I also look at the handbooks of the new mathematics conceptions suggested in the US, in order to have a comparison to see how the suggested conceptions were adapted to serve values and expectations in Luxembourg. My study shows that in one hand, Luxembourg had a very tight cooperation with OEEC/OECD, and on the other hand, there was the local culture and beliefs about the role of mathematics and the expectation from the future citizens. Besides the restriction that multilingualism made for preparing textbooks, moral and religious values also played their tremendous roles. In that situation, Luxembourgian educational-policy makers had to go through many delicate and time-consuming dialogues which are an interesting area of study. In this paper, I study how the ideology of New Math has been justified and adapted to be acceptable in the Luxembourgish culture.   [less ▲]

This study analyses the relationship between creativity and personality in different cultural contexts. A multivariate approach to creativity implies that personal and contextual characteristics influence creative performance. Is the relationship between creativity and personality the same in different cultural contexts? Within education the cultural factor might have more impact than in other environments because of assimilationism of migrant students. This study is carried out in London and the Greater Region of Luxembourg. The sample consists of 243 participants (199 women, 44 men, MAge = 20.35, SD = 1.56, age range: 18-32 years). Whereas the correlation between creativity and openness is positive for non-immigrants (European), it is negative for immigrants (non-European). This highly surprising exploratory result can be related to migration. A possible mediator between creativity and openness might be individual differences linked to migration, i.e. uncertainty avoidance. Implications of results will be discussed. [less ▲]

The present volume deals with the experience of ambivalence in family relations - a well-known phenomenon that has inspired more and more research and theorizing in the last years but that is however sometimes difficult to capture. Bringing together junior and senior researchers from different parts of the world, ideas on theory and research are elaborated following qualitative and quantitative approaches. This book thus contributes to theory-building as well as outlining research results and helping to develop measurement in interpersonal and intergenerational relations. [less ▲]

This paper investigates both theoretically and empirically the hypothesis that individual environmental attitudes can be partly accounted for by a cultural component. To empirically identify this component, we exploit variation associated with international migration flows. We find that the environmental attitudes of migrants, while being resilient to environmental conditions, also embed a cultural component, which persists till the second generation migrants. Our results suggest that, in the presence of multiple environmental problems that require collective action, comprehending the driving forces behind the formation of an environmental culture is critical to design effective policies.
