The allelopathic activity of barley (Hordeum vulgare L. ssp. vulgare) root exudates was studied by comparing their effects on seedling establishment in barley itself and in two weed species, Bromus diandrus Roth. and Lolium rigidum Gaudin, using an original laboratory protocol, named ‘seed-after-seed’. In this protocol, the donor and the receiver species of watersoluble allelochemicals are grown one after the other in the same dishes, in conditions reducing resource competition between both species. Growth of all receptive species (weeds and barley) was inhibited in a dose-dependent manner, when using increasing barley seed densities (0, 8, 19 and 25 seeds per Petri dish). In our conditions, the barley varieties and landraces exhibited different allelopathic activities against weeds or barley. The allelopathic potential of the barley root exudates was also dependent on the receiver species. Indeed, the released allelochemicals proved to be more toxic against the weed plants than on barley itself. Furthermore, the toxicity of the allelochemicals increased after their release by roots, between day 0 and day 6. These allelochemicals might contribute to the plant community dynamics and their usefulness as bio-herbicides deserves further consideration. [less ▲]

Les familles recomposées font face à de multiples transitions.Au cœur de ces transitions, différents processus de redéfinition interactionnelle et mythique sont attendus. Parmi ceux-ci, la construction des nouvelles appartenances qui prévoit la gestion des ruptures ainsi que la construction de nouveaux repères affectifs et sociaux. Dans la pratique psychothérapeutique, nous rencontrons souvent des couples et des familles qui ont « mal » aux transitions et qui se proposent comme « suspendues » entre un passé non reproductible et un futur imperceptible. A travers des situations cliniques et de recherche avec des familles recomposées, l’intervention portera sur l’intérêt d’aborder ces transitions complexes à travers le concept de perte ambiguë. Ce travail prévoit, non pas tant une élaboration définitive des précédentes appartenances mais bien une co-création de ponts affectifs entre le passé et le présent, l’écriture de nouveaux scripts pour le futur ainsi que la gestion d’appartenances multiples et ce, également à travers la re-dynamisation de ressources et de potentialités évolutives chez les couples, familles et leurs réseaux.

Dairy production has presented in Vietnam since 50 years, but these dairy farms really developed from 2001. In the period 2001 – 2010, the average growth rate of dairy herds was up to 30% per year. However, fresh milk production satisfies about 20-25% of milk consumption. The rural areas of Hanoi Province are large for dairy production. This province builds the 7 agro-ecological sub-regions for the development of dairy farming, in which Ba Vi District is a most of sub-regions for dairy production development. But the average size is about 2.5 cows per farm. This research aims to better understand how the factors in milk sector adapt to current economic conditions in Hanoi suburbs through analyzing farming systems. These studies were conducted from January to August 2012 on 43 dairy farms with different production scales at Ba Vi District to characteristic of dairy farming systems. The data were collected by interviewing and keeping records at the farms that have milk production. The results showed that three dairy production systems in these zones: (1) Dairy small farming system has from 1 to 3 cows per farm; (2) The medium farming system has from 4 to 5 cows per farm; and (3) The dairy intensive farming system has more 5 cows per farm. The economic activities were really diversified with landless per household farm such as rice production, gardens, grass production and sylviculture. Land resources per farm of intensive farming system were largest including 9,239 m² for garden around the household; 2,574 m² for rice land; 563 m² of grass area and 3,325 m² for sylviculture. While the small farming system has the lowest potential land, each household has only 2,815 m² of garden; 1,795 m² of rice land; 2,095 m² of grazing land. The medium farming system has about 3,150 m² of garden; 2,220 m² of rice land and 3,891 m² of grazing land. Milk production cycle was quite long with intensive farming system, up to 324 days comparing with 299 days per cycle with medium farming system and to 306 days per cycle with small-scale farmers. This difference was not statistically signification (P> 0.05). Average milk production yield per cow was high with medium farming system (16 kg per cow per day) in comparison with 15 kg per day at intensive and small farming systems (P> 0.05). Milk production yield has been improved in the past years with crossbreed cows such as Holstein-Friesian 50% and 75%. But this productivity was still considered to be lower than the milk production yield with dairy cows raised in Moc Chau District under Son La Province with 20.5 kg per cow per day and 6,250 kg of milk per cow per cycle). In addition, in the period from 2006 to 2012, fresh milk prices at farm gate have continued to rise for the farmers, while feed prices increased in the period from 2006 to 2010 and these feed prices were stable between 2011 and 2012. In the period of 2006 to 2012, fresh milk prices at farm gate increased from 0.17 USD per kg in 2006 to 0.60 USD per kg in 2012 and feed prices were from 0.15 USD per kg in 2006 increasing to 0.39 USD per kg in 2012. The net incomes were calculated per a cow per year reached 1,274 USD with the small-scale farming households to 1,476 USD with medium farming system. The net income per kg of fresh milk at farm gate obtained from 0.28 USD with small farming system to 0.31 USD with medium farming system. The net household income was high from dairy production, from 2,437 USD per farm per year with small farming system to 5,487 USD per farm per year with intensive farming system. The net labor family income gained from 997 USD per active per year with small farming system to 2,757 USD per active per year with intensive farming system. Thus, dairy production farms in recent years in Hanoi Suburbs provide very high economic efficiency for farmers in comparison with other agricultural activities at the farms. This explains why the rate of dairy family farming has grown very fast in the studied zones in the period from 2009 to 2012. This trend will continue to grow in the future. This research was also showed that the price of fresh milk plays a crucial role for profitable at farm level. But medium farming system with the size from 4 to 5 dairy cows per farm is more profitable with current economic conditions at farms. [less ▲]

Objective. When reminded of their neurological history, mild traumatic brain injured (TBI) students underperform on neuropsychological tests (Suhr & Gunstad, 2002). To date, this “diagnosis threat” (DT) phenomenon has mainly been studied with a non-clinical and high-functioning population (university students). The aim of this study was twofold: to study this phenomenon with neurological patients and to examine the mechanisms responsible for underperformance. Method. Patients (18-55 years-old) who had sustained a TBI or a stroke were recruited from ambulatory and hospitalized cares, and then assigned to one of three conditions : Patients attention was drawn on (1) their neurological disease and the neuropsychological components of the upcoming tasks (DT group) ; (2) their intact sensory capacities and the sensorial components of the tasks (Neutral group); or (3) their better cognitive abilities compared to Alzheimer disease patients (Stereotype boost group). After these instructions, patients carried out cognitive tasks and completed questionnaires. Results. Preliminary analyses (n=18) showed that, on the z-score of executive functioning, the DT group performed worse than both the neutral group (p=.03) and the stereotype boost group (p=.05), but did not differ for the attentional and memory scores. Instructions also had an impact on cognitive self-efficacy, with the neutral group demonstrating greater score than the negative one (p=.08). Furthermore, the self-efficacy score tended to correlate with the score of executive functioning (r=.37). Conclusions. Results show that the DT phenomenon has an impact on cognitive performances in clinical setting, at least on executive functions, which are usually demonstrated to be the most sensitive to stereotype effects.

The study of procedural learning abilities in children with Specific Language Impairment (Procedural Deficit Hypothesis, PDH; Ullman & Pierpont, 2005) remains a relatively unexplored field of research. Since most evidence comes from studies using tasks which involve learning of sequenced patterns, research using other procedural learning paradigms (like motor adaptation tasks) is needed to further evaluate the PDH in children with Specific Language Impairment (SLI). Therefore, in this study, we examined the ability of children with and without SLI to learn, consolidate and generalize a mirror-tracing task, a paradigm that does not involve sequence learning and had never been used in SLI. Children with SLI and typical developing (TD) matched children participated in the study. Children with SLI were included if they scored below -1.25 SD of the expected normative performance in at least 2 language areas. Both groups had to trace ten 5-pointed stars seen only in mirror-reversed view in two learning sessions separated by a one-week delay. The transfer phase consisted in tracing a new figure. The time required to complete the tracing, and the number of errors committed were recorded. Full results will be presented and discussed during the presentation of the paper. [less ▲]

S’inscrivant dans un contexte complexe, la production architecturale des années 1930 offre un visage bigarré reflétant les bouleversements technologiques, formels, politiques et sociaux d’une société en quête de stabilité. Les innovations de la nouvelle architecture développées au lendemain de la guerre trouvent peu d’écho à Liège. Alors que des personnalités comme Huib Hoste ou Victor Bourgeois se lancent dans un rationalisme d’inspiration internationale, Liège continue de miser sur le régionalisme ou sur le style Beaux-arts. Il faut attendre la fin des années 1920 pour voir apparaître les premiers signes d’une remise en question des principes académiques. La conférence replacera en premier lieu l’architecture au centre du débat culturel. L’analyse de la scène éditoriale liégeoise permettra notamment d’identifier précisément les tensions qui ont animé la scène professionnelle locale et qui ont largement débordé du cadre restreint de l’architecture. Au niveau de la production, l’exposé abordera plusieurs typologies qui ont marqué les années 1930 comme le logement social, l’habitation unifamiliale, l’immeuble à appartements ou les infrastructures publiques.
