European societies are reshaping and young generations in particular face the subsequent economic and social changes. The current economic crisis exacerbates the risk of youth poverty, aggravates social exclusion, and threatens the overall integration and participation of young people (Willems, Heinen & Meyers, 2012). Policymakers as well as stakeholders of the practical field have to find answers and solutions to tackle these challenges. They need reliable knowledge and systematic information to develop appropriate and effective measures. Social reporting generating “information on social structures and processes and on preconditions and consequences of social policy, regularly, in time, systematically, and autonomously” (Zapf, 1977, p.11) can provide an important evidence base for the decision-making process in policy and praxis. Our contribution starts with the argument that in modern knowledge societies, the autonomy of science has decreased and has become more open to politics and praxis. This becomes obvious by an increasing importance of co-production and participation in science and research (Nowotny, 2001; Weingart, 1997). Using the first Luxembourgish youth report as an example, we outline its underlying innovative concept of participatory social reporting. The report’s main characteristic is the systematic involvement of experts from the fields of policy, practice and research throughout the entire period of reporting. It aims to open the research process to experts and to integrate their professional knowledge (Willems et al., 2010). The presented concept of youth reporting is not an autonomous and exclusive process reserved to researchers. It is rather a “hybrid panel” (Lüders, 2006) where evidence is negotiated in a co-productive process between researchers and experts. Thus, the concept is characterised by its open, participatory and dialogue approach. We show how this concept was realised in the different phases and how it contributes to the reporting process: (1) In a first phase to explore socially relevant topics and issues and to define an agenda, (2) in a second phase to generate evidence and (3) in a final phase to define measures and actions for policymakers.

Transition from study to work is considered as the end of youth. How doyoung people prepare to enter the labour market? What are the strategies youngpeople utilise to become employed if it occurs in another country, as in the case ofemployment mobility? To answer these questions, the proposed article focuses on howyoung people move and enter the employment in other destination countries.Alongside with the literature on youth and transition we also observe that youngpeople equally experience challenges of matching their skills in the destinationcountries. They relate to inequalities on the job market depending on their skills, theirqualifications, the type of jobs, their working experiences, etc. The discussions in thispaper thus first touch upon the topic of inequality with regard to the process ofrecruitment and becoming employed. Second, they draw attention to the inferiorpositioning that young people are prepared to put themselves into when entering thelabour market for the first time and emphasise the fact that young people oftenexperience discrimination and unequal treatment when they complete education andapply for jobs, on the grounds of being young and inexperienced. As a result, such apositioning often puts young people in a vulnerable situation, which they accept andendure as long as they are promised work. Furthermore, by focusing on how youngpeople enter the labour market in the receiving country, the paper also exploresstrategies that young people apply for being employed, becoming integrated in thelabour market, overcoming inequalities in employment and finding ways to cope withthese challenges in the labour market, as well as their own social lives in thedestination country [less ▲]

From a sociological perspective youth as a life phase is mainly characterized by processes of socialization and individual development on the one hand and the managements of transitions to adulthood on the other. Transitions to adulthood are related to young people’s development of social and economic independence and their societal integration and participation. Transitions have changed substantially over the past decades: they are postponed, de-standardized and supposed to be rather subject to individual choice than the result of prescribed patterns. Hurrelmann distinguishes four domains of transition: (1) the development of intellectual and social competence (in order to achieve the occupation role), (2) the ability to enter a relationship (in order to fulfil the partner and family role), (3) the ability to use the market (in order to enter the consumer role) and (4) the development of a system of norms and values (in order to assume the political citizen role). From a functionalist point of view, these tasks form the key dimensions for societal integration. Young people have to assume certain social roles in order to maintain the continuity of the society. But in the perspective of a theory of action, social roles also form the key elements for the individual development. Young people are considered to be active agents and “navigators” that call the offered social roles and role behaviours into question and develop them further. hese theoretical concepts form an important reference for the migration and integration research as well. Since the developmental tasks refer to an individual life-course perspective, the focus of migration and integration research is rather on the institutions and the participation of young migrants. Based on the scientific discourse in the field of migration research Willems, Filsinger and Rotink define four main dimensions of integration: structural integration (education, employment), cultural integration (values, normative orientation, language), social integration (friendship, peer group), and identity integration (sense of belonging to the host society). The present article takes up some of these dimensions in order to describe the situation of young migrants in Luxembourg. It presents selected empirical data for the Grand Duchy and focuses on the different dimensions of integration. [less ▲]

Parafermions are emergent excitations which generalize Majorana fermions and are potentially relevant to topological quantum computation. Using the concept of Fock parafermions, we present a mapping between lattice Z4-parafermions and lattice spin-1/2 fermions which preserves the locality of operators with Z4 symmetry. Based on this mapping, we construct an exactly solvable, local one-dimensional fermionic Hamiltonian which hosts parafermionic edge states. We numerically show that the parafermionic phase remains stable in a wide range of parameters, and discuss its signatures in the fermionic spectral function. [less ▲]

The present thesis deals with a development of linear algebra, geometry and analysis based on (Z_2)^n-superalgebras: associative unital algebras which are (Z_2)^n-graded (for some natural number n) and graded-commutative, i.e., satisfying ab = (-1)^<deg(a),deg(b)> ba, for all homogeneous elements a, b of respective degrees deg(a), deg(b) in (Z_2)^n, and < . , . > denoting the usual scalar product. This generalization widens the range of applications of supergeometry to many mathematical structures -- the algebra of quaternions H and more generally Clifford algebras, Deligne algebra of superdifferential forms, higher vector bundles ... -- and appears also in physics -- for describing anyons, paraparticles -- proving its worth and relevance. In this dissertation, we first focus on (Z_2)^n-superalgebra theory: we define and characterize the notions of trace, determinant and Berezinian of matrices over graded-commutative algebras. Special attention is given to the case of Clifford algebras, where our study gives a new approach to treat the classical problem of finding a “good” determinant for matrices with non-commuting (quaternionic) entries. Further, we undertake the study of (Z_2)^n-graded differenital geometry. Privileging the ringed space approach, we define (smooth) (Z_2)^n-supermanifolds modeling their algebras of functions on the (Z_2)^n-commutative algebra of formal power series in graded variables, and develop the theory along the lines of supergeometry. Notable results are: the graded Berezinian and its cohomological interpretation (essential to establish integration theory); the theorem of morphism, which states that a morphism of (Z_2)^n-supermanifolds can be recovered from its coordinate expression; an analogous of Batchelor-Gawedzki theorem for (Z_2)^n-supermanifolds.

Two laboratory studies were carried out to assess the behavior of the active palmar sweat glands in both an active and a passive coping situation. Stressor in study I was watching a distressing film, in study II mental arithmetic. Subjects were male students, 17 in experiment I, 20 in experiment II. Both experiments involved a 10-minute baseline phase, a 10-minute stress period, and a follow-up of 10 minutes. PSI was assessed at 90-sec intervals and averaged across phases, as were readings in SCL, SCR, heart rate, diastolic and systolic blood pressure. PSI could be determined in 16 subjects of each study. In both experiments PSI increased significantly from baseline to stress (p less than 0.1%) and decreased from stress to follow-up (p less than 0.1%), and thus proved to be the most sensitive indicator for stress. The interrater reliability for counting the number of active sweat glands was high when the area for evaluation was defined unambiguously. Since the assessment of the PSI does not require a sophisticated technology and is thus also applicable in field research, we suggest giving more consideration to this variable. [less ▲]
