Recently, Balakirev et al. (2013) presented a taxonomic revision of the genus Leopoldamys based on phylogenetic analyses. They identified five main Leopoldamys genetic lineages and suggested to rename several of them. According to these authors, the genetic lineage previously thought to belong to L. edwardsi (lineage L1) should be assigned to L. revertens while L. neilli (lineage L2) should be considered as a junior synonym of L. herberti. Using molecular and morphological data from a large sampling of Leopoldamys specimens, the aim of the present study was to investigate the taxonomic status of L. herberti and L. neilli. This study reveals that, contrary to Balakirev et al.’s statement, both genetic lineages L1 and L2 occur in Nakhon Ratchasima Province, close to the type locality of L. herberti. We also show that the external measurements and color pattern of L. herberti are highly similar to those of L1 specimens but are not consistent with the morphology of L2 specimens. Therefore these results strongly suggest that L. herberti should be assigned to the genetic lineage L1. Consequently L. neilli should not be considered as a junior synonym of L. herberti and this study confirms that the appropriate name of the genetic lineage L2 is L. neilli. Moreover, as our results show that L. herberti should be assigned to the lineage L1, this name has nomenclatural priority over L. revertens, the species name suggested by Balakirev et al. (2013) for this lineage. [less ▲]

Assuming a given educational policy, the recent brain drain literature reveals that skilled migration can boost the average level <br />of schooling in developing countries. In this paper, we introduce educational subsidies determined by governments concerned by <br />the number of skilled workers remaining in the country. Our theoretical analysis shows that developing countries can benefit from <br />skilled emigration when educational subsidies entail high fiscal distortions. However when taxes are not too distortionary, it is <br />desirable to impede emigration and subsidize education. We then investigate the empirical relationship between educational <br />subsidies and migration prospects, obtaining a negative relationship for 105 countries. Based on this result, we revisit the country <br />specific effects of skilled migration upon human capital. We show that the endogeneity of public subsidies reduces the number of <br />winners and increases the magnitude of the losses. <br />© 2008 Elsevier B.V. All rights reserved. [less ▲]

Developmental Coordination Disorder (DCD) is a developmental disorder characterized by marked impairments in motor skills. Despite its negative impact on daily activities and on cognitive and academic performance, the mechanisms underlying this disorder remain largely unknown. One hypothesis that has been proposed is that the poor motor coordination abilities may be attributed to impairments in motor learning and, more specifically, in learning of the correct sequencing of movements (Gheysen et al., 2011). To date, only two studies have directly investigated sequence learning in DCD, but their results are contradictory. The aim of this study was to explore learning of motor sequence in DCD children by means of a modified version of the Serial Reaction Time (SRT) task where the standard keyboard was replaced by a touch screen in order to reduce the impact of the DCD group’s motor difficulties. A total of 34 children (17 with DCD and 17 typically developing (TD) children aged between 6 and 12 years old participated in this study. Results show that DCD children were able to learn the sequence as fast and as accurately as TD children. These findings, showing that children with DCD present the same degree of implicit learning as TD children, differ from those obtained by Gheysen et al. (2011) and so, challenge the motor sequence learning deficit hypothesis. We suggest that differences between studies are not related to an implicit sequence learning deficit per se in children with DCD, but rather to methodological aspects like the response mode used in the studies.

The recent downward revision of the solar CNO photospheric abundances now leads to severe inconsistencies between theoretical models for the Sun's internal structure and the results of helioseismology. There have been claims that the solar Ne abundance may be underestimated and that an increase in this ill-defined quantity could alleviate (or even completely solve) this problem. To address the validity of this hypothesis, we present a fully homogeneous non-LTE abundance analysis of the optical Ne I/II lines in a sample of 18 nearby B-type stars. Our very preliminary results point towards a mean neon abundance slightly higher than the new solar value, but apparently insufficient by itself to restore the agreement between the solar models and the helioseismological constraints.

Current evidence suggests that pollen is both chemically and structurally protected. Despite increasing interest in studying bee-flower networks, the constraints for bee development related to pollen nutritional content, toxicity and digestibility as well as their role in the shaping of bee-flower interactions have been poorly studied. In this study we combined bioassays of the generalist bee Bombus terrestris on pollen of Cirsium, Trifolium, Salix, and Cistus genera with an assessment of nutritional content, toxicity, and digestibility of pollen. Microcolonies showed significant differences in their development, non-host pollen of Cirsium being the most unfavorable. This pollen was characterized by the presence of quite rare δ7-sterols and a low digestibility. Cirsium consumption seemed increase syrup collection, which is probably related to a detoxification mixing behavior. These results strongly suggest that pollen traits may act as drivers of plant selection by bees and partly explain why Asteraceae pollen is rare in bee generalist diet. © 2016 Institute of Zoology, Chinese Academy of Sciences.

Een systematic review of systematisch literatuuronderzoek wordt meestal gebruikt om een samenvatting te maken van de resultaten van meerdere studies over hetzelfde onderwerp. Systematische literatuurstudies zijn dus heel belangrijk, in het bijzonder de voorbije jaren, waarin het aantal in de literatuur gepubliceerde artikelen is geëxplodeerd! Een systematic review wordt beschouwd als een onderzoek met een hoog wetenschappelijk bewijsniveau. Het staat aan de top van de piramide van de evidence-based medicine.

INTRODUCTION AND AIMS Vegetative state/Unresponsive wakefulness syndrome (VS/UWS) is defined by the presence of eye-opening and the absence of awareness and voluntary movement (Laureys et al., 2010). VS/UWS patients classically receive hydration and nutrition through an enteral feeding tube. We present the cases of two patients that were diagnosed as VS/UWS but were able to resume oral feeding. It is however unclear if the presence of oral feeding is compatible with the diagnosis of VS/UWS or if this observation should lead to a modification of the diagnosis. METHODS AND RESULTS We retrospectively reviewed the clinical information of 65 VS/UWS patients (aged 45±12; range 16-85 years) evaluated at the CHU hospital of Liege searching for mention of oral feeding. VS/UWS diagnosis was made after repeated behavioral assessments using the standardized Coma Recovery Scale–Revised (CRS-R, (Teasdale & Jennet, 1974)) in association with complementary evaluations using neuroimaging techniques. Of the 65 VS/UWS patients, two could resume oral feeding (3%). One could achieve full oral feeding (mixed texture and liquid) and the other had oral feeding (liquid and semi-liquid) in addition to gastrostomy feeding. Neuroimaging evaluations showed in both patients a massive decrease in the spontaneous brain activity and its functional connectivity (using functional magnetic resonance imaging), bilateral cerebral cortex hypometabolism (fronto- parietal associative areas, posterior parietal areas, cingulate cortices, precuneus) and preserved metabolism in the brainstem and cerebellum (using positron emission tomography). CONCLUSIONS Oral feeding is rare in VS/UWS patients (3% in our cohort). Based on neuroimaging results, this behaviour does not seem to be incompatible with the diagnosis of VS/UWS but the neuromecanistic root, which allows this behavior, still needs to be elucidate. This study also emphasizes the importance of systematic swallowing evaluation in patients with altered state of consciousness regardless of their level of consciousness. Moreover, tactile oro-facial stimulation, manual therapy, taste stimulation and therapeutic feeding can be another “gateway” to interact with these patients and improve their quality of life.

Organic farming is considered to be one of the solutions for the problems of sustainability faced today by the agriculutral sector. This paper describes the growth of the Walloon organic sector during the last years thanks to the support of the regional authorities through financial incentives and a new regional strategic development plan. It also presents some results collected during an on-farm survey concerning organic cereals. It appears that organic farming has significantly developed thaks to public support even if the prices of organic products are exceeding by 30% those of conventional products. Organic farming can play a significant role in the future of Walloon agriculture. However, due to the high conversion rate during these last years, it is not guaranteed that the financial support could be conserved at a such level. [less ▲]
