Former German minister of the interior Otto Schily highlighted: “Anyone who closes music schools jeopardizes inner security.” In his large study at primary schools in Berlin at the end of the 1990th, Hans Günter Bastian found out that common music practice and extended music education can lead to more social competence. In my lecture, I will give three examples of how music making cannot only avoid violence and criminality, but can also contribute to well-being among like-minded people. 1) The movie The Choir (les choristes) is a perfect demonstration, how common singing is able to weld together an initial heterogenous group of difficult educable children living in institutions of care 2) El Sistema is a famous programme for children in Venezuela financed by the state with the main objective that “music has to be recognised as an agent of social development” as José Antonio Abreu, its initiator highlights. 3) In my last year’s lecture, I presented my mail choir with an age average beyond 70 years. Recently I published a study on interviews conducted with the choristers to find out their views of social well-being." [less ▲]

The eel (Anguilla anguilla L.) is a fish that is mainly found in European waters. The River Moselle is among the bodies of water inhabited by this specimen. During the downstream migration into their Atlantic spawning ground, silver eels often experience severe to fatal injuries while passing the turbines at the barrages. This annual migration takes place in a relatively narrow timeframe. Therefore, knowing the trigger or beginning of said migration, the mortality rate of the eels could be reduced by a fish-adapted turbine control or comparable protective measures. This thesis introduces an early warning system, which predicts the periods of silver eel emigration by means of certain abiotic factors. On the basis of the information gleaned from different studies and the experience gained from many years of professional fishing, those environmental factors were identified which are connected with the migration of the silver eel. Extensive data analyses were used to substantiate these findings. The water flow, the flow differences and the lunar phase were particularly relevant. Furthermore, the season and the water temperature were taken into account. In view of the different sources of information (experience and expert knowledge, data sets and the findings derived from it), a hybrid structure of the early warning system was realized. After examining different methods from the fields of soft computing and mathematics or statistics, the fuzzy logic (knowledge-based), the case-based reasoning (casebased) and the artificial neural networks (data-based) were selected. With each of these methods, an independent prediction model was designed, tested and optimized. Special characteristics were found during the data analysis and were taken into account by the use of adequate modifiers. The models were tested on the basis of the present data sets for the Moselle. It was shown that it is possible to correctly predict most of the situations with increased catches (suggesting a migration). Threshold values for a migration were defined based on the catches. The same was done for the forecast values. Thus, for the 1963 to 1973 data record, a total of 63% (artificial neural networks), 74% (fuzzy logic), and 83% (case-based reasoning) of the events with increased catches could be detected. Since not every situation with a favorable constellation of abiotic factors also led to a migration or higher catches, a lot of "false" forecasts (up to 50%) were made as well. Good results have also been achieved when using data from recent years and most events were identified. A stand-alone program was developed for the practical application of the prognosis models. This early warning system is a software which contains a user interface for reading data and displaying prognosis values and into which the developed prognosis models are implemented. In addition, recommendations for use were compiled and presented. [less ▲]

The feasibility and performance of applying a two-stage configuration for co-production of hydrogen and methane from maize silage in continuously stirred reactors was investigated under mesophilic conditions. The high organic loading used in the first-stage hydrogen producing reactor (e.g. load shock treatment) was effective at ensuring hydrogen-producing conditions, with no methanogenic activity observed for more than 60 days. A hydrogen yield of up to 53.8 NlH2/kg volatile solid (VS) was measured in the first reactor, with a hydrogen content of 33.1%. The methane yield in the second stage reactor was 133.9 NlCH4/kgVS, with a methane content of 65%. Abnormally low concentration of acetic acid and high concentrations of caproic acid were measured in the first reactor in the pH range 5–5.5, which could be explained by the presence of strains such as Clostridium kluyveri. Of the estimated total energy yield in the two-stage system, only 4% was from hydrogen production. The mixture of hydrogen and methane produced in the system (after carbon dioxide removal) is in the range recommended for use as vehicle fuel. [less ▲]

This Article attempts to define hedge funds and to distinguish them from a variety of similar investment funds. After reviewing the hedge fund definition in the U. S. and the EU, this Article argues that the current regulatory framework, which defines hedge funds by reference to what they are not rather than to what they are, is prone to regulatory arbitrage. Even in the presence of a statutory definition, due to the ineluctable indeterminacy of language and regulatory arbitrage problems, borderline issues will persist, which makes statutory definitions of hedge funds neither possible nor desirable. Therefore, regulators should avoid the temptation of proposing such statutory definitions. Instead, they should rely on regulatory discretion within a broad principles-based regulatory framework to do so. For such a principles-based regulatory regime to work, regulators should rely on a functional definition of hedge funds. Accordingly, this Article defines hedge funds as privately organized investment vehicles with a specific fee structure, not widely available to the public, aimed at generating absolute returns irrespective of market movements (Alpha) through active trading and making use of a variety of trading strategies. This functional definition is likely to help address regulatory problems that might originate from statutory definitions of hedge funds. [less ▲]

In his book „The Limits of Interpretation” (Bloomington, Indiana University Press, 1991) Umberto Ecco distinguished between the research of intentio operis and the subordination of a text to the intentio lectoris. In the first case is meant the “interpretation” of the text and in the second Ecco speaks of “using the text”. The importance of this thesis is that the intentio lectoris is at the origin of music education. Transferred to music one should consider the term intentio auditoris. If apprentices must be motivated to alter their intentio auditoris up to an intentio operis, they should take the opportunity to make the connection of their own intentionality with music, e.g. they must try to modify the subject. This is a crucial task for the music teacher. The importance of electronic media and new technologies are regularly at the center of research projects at European levels. The music teacher’s identity and his/her professionalism have to detect this distance between intentio auditoris and intentio operis (the latter having been trained during the studies) and work with conviction to reduce this distance. In addition s/he will justify and critically scrutinize at any time to him/herself and to the students the impact of his/her educational activities. The objective of my text is to portray the identity of music teachers from a European perspective, on one hand, by distinguishing between countries focusing more or less on the German tradition (the teacher as a musician), and, on the other hand, countries preferring the system as it applies on the francophone (the musician as teacher) or Anglo-Saxon countries. In general, identifying avenues for mutual enrichment between different traditions will be a goal of further research about cultural heritage. Identifying tracks for promoting a mutual cross-fertilization between and an understanding of different traditions will on the focus of this kind of activities. [less ▲]

In an organisational setting such as an online marketplace, an entity called the ‘organisation’ or ‘institution’ defines interaction protocols, monitors agent interaction, and intervenes to enforce the interaction protocols. The organisation might be a software system that thus regulates the marketplace, for example. In this article we abstract over application-specific protocols and consider commitment lifecycles as generic interaction protocols. We model interaction protocols by explicitly-represented norms, such that we can operationalise the enforcement of protocols by means of norm enforcement, and we can analyse the protocols by a logical analysis of the norms. We adopt insights and methods from commitment-based approaches to agent interaction as well as from norm-based approaches to agent behaviour governance. First, we show how to use explicitly-represented norms to model commitment dynamics (lifecycles). Second, we introduce an operational semantics to operationalise norm enforcement. Third, we show how to logically analyse interaction protocols by means of commitment dynamics and norm enforcement. The model, semantics, and analysis are illustrated by a running example from a vehicle insurance domain. [less ▲]

Socially assistive robots, when used in a way that takes into consideration children’s needs and developmental characteristics, can be useful tools to enable children’s development. More specifically, due to their characteristics (predictability, simplicity, and repetition) robots can be especially helpful to teach emotional abilities to children with autism spectrum disorder (ASD). Previous research has provided preliminary evidence that robots can help children improve in some domains such as joint attention and imitation. However, no studies have examined how robots can be integrated in intervention protocols targeting the acquisition of emotional abilities in children with ASD. This paper presents a work in progress on an emotional ability training developed for children with ASD using the QT socially assistive robot. This training aims to test whether children with ASD can benefit from a robot-mediated training to improve emotional ability. [less ▲]

Les classes en Europe se diversifient. Cette diversification transforme l’exercice du métier enseignant tout en lui offrant de nouvelles opportunités de développement. Cet article explore l’hypothèse qu’en utilisant des outils issus de paradigmes au départ distincts – les approches multimodales du discours issues de la sémiotique sociale et les travaux sur le plurilinguisme dans le champ de la linguistique appliquée – on peut faire émerger une vision plus compréhensive des dilemmes et des questions que la diversité pose, en particulier pour l’enseignant débutant. En partant de l’analyse d’une première leçon de français dans une classe très internationale et un contexte d’enseignement trilingue, l’article s’attache à dresser une première cartographie de ces dilemmes. Cinq défis en particulier sont relevés (relatifs à la différenciation, la reconnaissance du travail sémiotique, l’évaluation, la reconnaissance des répertoires des élèves, et aux compétences linguistiques des enseignants). La cartographie est posée comme un préalable nécessaire à une réflexion plus large sur les moyens d’action à mettre en oeuvre pour soutenir l’action enseignante en contexte linguistiquement hétérogène.

Verbal number skills (i.e. counting and number naming) are milestones in numerical development. The aim of the present study was to clarify the role of different verbal abilities (VA) and visuo-spatial abilities (VSA) in the development of these verbal number skills in kindergarten. We recruited 152 children (mean age: 5.8 years) and administered different measures of VA (e.g. phonological awareness, pseudoword recall) and of VSA (e.g. spatial perception, copying) to assess their contribution to verbal number skills. Firstly, we computed two independent regression models, a “VA only” model explaining 23% of variance, and a “VSA only” model explaining 38% of variance. Adding verbal measures to the “VSA only” model does not lead to a significant increase in R2. Our results show that VSA, rather than VA, contribute to a larger extent to children’s verbal number skills. Intriguingly, the development of verbal number skills builds on VA, but more importantly on VSA. These results are potentially informative for the conception early mathematics interventions.

Instead of alleviating fiscal inequalities, intergovernmental grants are often used to fulfill the grantors’ political goals. This study uses a unique panel dataset on the level of more than 500 Croatian municipalities over a twelve-year period to uncover to which extent grant distribution is biased due to grantors’ electoral concerns. Instead of the default fixed effects approach to model panel data, we apply a novel within-between specification aimed at uncovering the contextual source of variation, focusing on the effects of electoral concerns on grant allocation within and between municipalities. We find evidence of a substantial political bias in grant allocation both within and between municipalities, particularly when it comes to local-level electoral concerns. The paper offers researchers a new perspective when tackling the issue of politically-biased grant allocation using panel data, particularly in cases where they wish to uncover the simultaneous impact of time-variant and time-invariant factors, or when they cannot apply a quasi-experimental approach due to specific circumstances of the given institutional context.
