In Luxembourg, nearly half of the population is foreign – the foreign population percentage currently stands at 48%. Within this context majority and minority become fluid with the migration process itself being fluid, ranging from daily migration (transnational commuters), to medium-term stays, return visits and permanent immigration including uptake of citizenship. Second generation immigrants live alongside new arrivals. This heterogeneity has been described as super-diverse by Vertovec (2007). Diversity also goes beyond the level of country of origin as many individuals have very complex biographies. Culture contact is a permanent feature in daily life. Such a plurally composed society presents a challenge also for value transmission processes. The boundaries between enculturation and acculturation become blurred and norms, values, symbols and language may be negotiated dependent on context. The multicultural society of Luxembourg has provided different experiential contexts for different generations. Whereas the older generation grew up in a more homogeneous context, for the current cohort growing up with people of different cultural backgrounds and language skills is the norm. Reinders (2006) has introduced the term co-culturation, as distinct from enculturation and acculturation, to describe the process of engagement with cultural diversity by both, natives and those with migration background. This concept of co-culturation encapsulates the skill of negotiating different cultural contexts and cultural frame-switching – key skills in modern societies characterized by high mobility and migration. There is some evidence that nationality becomes more salient in multicultural contexts, but at the same time the importance of cultural origins may be weakened. As results from a pilot study among secondary school children (N = 85) suggests, friendship patterns are formed on the basis of characteristics of the individual rather than origin. In the sense of the individualist marginal as described by Bourhis et al. (1997), the findings suggest that young people want to be recognized by who they are rather than what they represent. Implications for cultural value transmission will be discussed. [less ▲]

Similar to neighbouring German varieties, the recent language history of Luxembourgish is subject to an ongoing merger of the alveolopalatal fricative [ɕ] (deriving from the palatal fricative [ç]) and the postalveolar fricative [ʃ], leading progressively to the collapse, for example, of the minimal pair frech [fʀæɕ] 'cheeky, impertinent' and Fräsch [fʀæʃ] 'frog'. The present study will draw on a large dataset— which has been recorded using an innovative smartphone application—consisting of fricative realisations of more than 1,300 speakers. In an acoustic analysis, various parameters of the two fricatives will be studied (Centre of Gravity, spectral moments, Euclidian distance, DCT coefficients) and correlated with the speaker’s age. The results show that the merger is acoustically manifest for nearly all age groups. Only the oldest speakers keep the two fricatives distinct. [less ▲]

Der Beitrag behandelt die komplexe Sprachensituation Luxemburgs, mit Fokus auf den germanischen Varietäten, i.e. Deutsch und Luxemburgisch, im Hinblick auf Überdachung und ihre sprachgeschichtlichen Verschiebungen. In dieser varietätenlinguistischen Perspektive liegt der Schwerpunkt auf der äußeren Sprachgeschichte; Aspekte der inneren Sprachgeschichte werden aus Platzgründen lediglich anhand ausgewählter Beispiele thematisiert.

Gene expression regulation is a fundamental cellular process that enables robust functioning of cells. How different genes interact among themselves to coordinate and maintain the overall gene expression profile observed in a cell is a key question in cellular biology. However, the immense complexity arising due to the scale and the nature of gene-gene interactions often hinders obtaining a global understanding of gene regulation. In this regard, network models of gene regulation based on gene-gene interactions, commonly referred to as gene regulatory networks (GRNs), serve important purpose of describing the overall interactions within a cell and provide a systematic approach to study their global behavior. In particular, in the context of cellular differentiation and reprogramming, where regulated changes in gene expression play a crucial role, precise knowledge of a cell type-specific GRN can enable control of the eventual cell fates with potential clinical applications. In this chapter, we describe our computational methodologies that we have tailor-made with purpose of applications to cell fate control. Briefly, we introduce the process of cellular differentiation and reprogramming, describe GRNs and common strategies to model them, and, finally, introduce the concept of determinants of cellular reprogramming and differentiation. In the Methods section, we elaborate on the different steps involved in the computational pipeline, including initial gene expression data processing, characterization of prior knowledge network, algorithm to remove non-cell type-specific edges, topological characterization of the inferred network, and Boolean network simulations to mimic cellular transitions. Finally, we provide a strategy to identify determinants of cellular reprogramming and differentiation based on the proposed computational methods. [less ▲]
