Reservoir compensation releases : impact on the macroinvertebrate community of the Derwent River, Northumberland, UK-A longitudinal

River regulation for the purposes of public water supply causes the flow regime downstream of a dam to change. Traditionally, in the UK, such regulation was accompanied by requirements for reservoir releases to compensate downstream water users (e.g. industry) for the loss of natural flow (compensation flows). In this article, we compare a unique pre-impoundment macroinvertebrate data set for a regulated upland river with survey data post-impoundment. This allows a longitudinal assessment of the response of the system to regulation. The Derwent River, Northumberland, was impounded in 1966. Impacts on the hydrological regime were quantified by comparing long-term hydrographs, flow duration curves, flow ranges and flashiness indices for the pre-impoundment and post-impoundment periods. The comparison of changes in macroinvertebrate richness and diversity post-impoundment showed that the change in flow regime has had limited effect on the ecological community structure. The flow regime of the Derwent River has become less flashy with fewer extreme events, and the richness and the diversity of macroinvertebrates have, in some cases, increased and at worst have not deteriorated. We suggest that this reflects the strict compensation regime, which has guaranteed minimum flows at all times. Copyright (c) 2012 John Wiley & Sons, Ltd.

Entre hybris et mélancolie : poétique, esthétique et usages de la liste dans le roman français contemporain (1963-2013)

Forme archaïque, présente dès l'aube de l'écriture; forme ergonomique, présente autour de nous de manière bien plus courante que toute narration; la liste est un objet fascinant, qui ne dévoile jamais autant sa complexité que lorsqu'elle apparaît dans un cadre littéraire. Un cadre permettant de questionner, en les confrontant, la liste et son énonciateur - son sujet. Qui parle quand une liste se dit? Que dit-elle de celui qui l'énonce? Qui parle, lorsque la syntaxe se bouleverse au point de détruire les hiérarchies permettant habituellement de fixer au discours une origine, une destination, une reprise en charge? Il s'agira de répondre à ces questions et donc de passer d'une poétique à une éthique de la liste, afin de montrer que la description d'un tel objet est indissociable de sa contextualisation discursive, sa subjectivisation. Celle-ci traverse, par une constante métalepse (glissement entre les instances de responsabilité du discours), tout le spectre des actants du texte-liste - de la figure d'auteur à celle du lecteur. La spécificité de la liste littéraire se déporte alors dans un espace éthique, puis bientôt thymique, constitué par un faisceau d'oppositions : par exemple, la liste peut être fermée ou ouverte, hyper- ou hypolisible ; signe d'ordre (c'est l'inventaire, où à l'item correspond la chose) comme de désordre (c'est l'accumulation proliférante). Mais le couple oppositionnel le plus fécond est constitué par l'hybris et la mélancolie: hybris, ou l'orgueil de croire à une réinvention du monde par le pouvoir d'une juxtaposition sans limites. Mélancolie, ou miroitement du mot manquant, évidence de l'absence. C'est sous l'égide de cette opposition que je traite un vaste corpus constitué de huit auteurs contemporains, marqués par un XXe siècle catastrophique, où à l'hybris pléthorique de l'expression de la monstruosité et de l'abondance (J-M.G. Le Clézio, Georges Perec, Eric Chevillard) répond la mélancolie d'une absence ontologique : identitaire (Patrick Modiano), épistémologique (Pierre Senges) langagière (Pascal Quignard, Olivia Rosenthal), voire politique (Antoine Volodine).

Supporting interdisciplinary case studies: development and implementation of a joint learning environment for students in forensic science and criminal law

Scientific reporting and communication is a challenging topic for which traditional study programs do not offer structured learning activities on a regular basis. This paper reports on the development and implementation of a web application and associated learning activities that intend to raise the awareness of reporting and communication issues among students in forensic science and law. The project covers interdisciplinary case studies based on a library of written reports about forensic examinations. Special features of the web framework, in particular a report annotation tool, support the design of various individual and group learning activities that focus on the development of knowledge and competence in dealing with reporting and communication challenges in the students' future areas of professional activity.

Roman d'apprentissage et liberté romanesque

RésuméA l'image de son personnage, qui se déplace en subissant toutes sortes d'expériences lui permettant de « grandir », le roman d'apprentissage traverse les siècles et les cultures en Occident, mais trouve aussi un écho tout à fait particulier parmi de nombreux romans d'Afrique noire francophone. Ce genre littéraire se découvre tant parmi les productions de l'époque coloniale que parmi les plus contemporaines et peut être envisagé en tant que métaphore d'une autonomie langagière et littéraire progressivement acquise, tout en gardant à l'esprit que les catégories génériques occidentales n'ont pas à être dupliquées telles quelles sur les productions fictionnelles africaines. L'hypothèse de travail associe les dimensions diachronique et synchronique pour observer un croisement de pratiques formelles et génériques dans les textes de fiction romanesque d'Afrique subsaharienne. Elle utilise dans ce cadre les romans Karim d'Ousmane Socé (1935) et Une Vie de boy de Ferdinand Oyono (1956).AbstractLike their protagonists, who undergo a journey and in the process come of age, coming-on-age novels have abounded and evolved throughout the centuries in the West - but they are also present in sub-Saharian African literature. The coming-of-age genre was popular during colonial times and is even more so today. Where African Francophone literature is concerned, we can take this type of novel as a metaphor for its gradually acquired linguistic and literary autonomy, keeping in mind that Western genres and patterns cannot be applied willy-nilly to this new generation of African litterateurs. Taking into account both historical and territorial aspects, we will examine African Francophone literature, stylistically and thematically, in its approch to gender. To do so, we will analyse Ousmane Socé's Karim (1935) and Ferdinand Oyono's Une vie de boy (A boy servant's life, 1956).

Functional compensation of motor function in pre-symptomatic Huntington's disease.

Involuntary choreiform movements are a clinical hallmark of Huntington's disease. Studies in clinically affected patients suggest a shift of motor activations to parietal cortices in response to progressive neurodegeneration. Here, we studied pre-symptomatic gene carriers to examine the compensatory mechanisms that underlie the phenomenon of retained motor function in the presence of degenerative change. Fifteen pre-symptomatic gene carriers and 12 matched controls performed button presses paced by a metronome at either 0.5 or 2 Hz with four fingers of the right hand whilst being scanned with functional magnetic resonance imaging. Subjects pressed buttons either in the order of a previously learnt 10-item finger sequence, from left to right, or kept still. Error rates ranged from 2% to 7% in the pre-symptomatic gene carriers and from 0.5% to 4% in controls, depending on the condition. No significant difference in task performance was found between groups for any of the conditions. Activations in the supplementary motor area (SMA) and superior parietal lobe differed with gene status. Compared with healthy controls, gene carriers showed greater activations of left caudal SMA with all movement conditions. Activations correlated with increasing speed of movement were greater the closer the gene carriers were to estimated clinical diagnosis, defined by the onset of unequivocal motor signs. Activations associated with increased movement complexity (i.e. with the pre-learnt 10-item sequence) decreased in the rostral SMA with nearing diagnostic onset. The left superior parietal lobe showed reduced activation with increased movement complexity in gene carriers compared with controls, and in the right superior parietal lobe showed greater activations with all but the most demanding movements. We identified a complex pattern of motor compensation in pre-symptomatic gene carriers. The results show that preclinical compensation goes beyond a simple shift of activity from premotor to parietal regions involving multiple compensatory mechanisms in executive and cognitive motor areas. Critically, the pattern of motor compensation is flexible depending on the actual task demands on motor control.

Enhancing centralized enforcement of EU law : Pandora's toolbox ?

State compliance with EU Law is crucial to the very existence of the Union. Traditionally, it has been secured through a combination of strong "private" and of weak "centralized" enforcement. However, this arrangement is no longer perceived to be sufficient. By endowing the Union with new tools vis-à-vis its Member States - penalties, conditionality, and the like - current reforms try to complement symbolic sanctioning with real "consequences". The goal is to reinforce the authority of EU Law. In this article, we question whether the new toolbox is fit for the purpose, or whether it risks to produce adverse effects which might even go as far as upsetting the Union's constitutional template.

Yearbook of Private International Law, Volume XIV, 2012/2013

The "Yearbook of Private International Law" provides all about the conflict of laws developments of 2012 and 2013 in one book: Volume XIV (2012/2013) includes contributions on the proposed codification of the General Part of Private International Law in Europe, on the reform of the Chinese legal system as well as on defamation and violation of personality rights (the latter in a whole section). Furthermore, the book deals with the application of EU legislation on jurisdiction and enforcement of judgements, the recognition of judgements overturned by another judgement, and the conflict of decisions in international arbitration. Reports and court decisions from the Netherlands, Turkey, India, Finland, Croatia and Switzerland and a summary of two dissertations on the role of sovereignty and choice of courts agreements complete the book.
