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 ▲]Detailed reference viewed: 27 (4 ULg)

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.

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.

Is neon a viable solution to the solar model problem? Insights from nearby B-type stars

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.

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 ▲]Detailed reference viewed: 22 (4 ULg)

Objective: A large trial published in 2000 concluded that planned vaginal delivery of term breech births is associated with high neonatal risks. Because the obstetric practices in that study differed from those in Countries where planned vaginal delivery is still common, we conducted an observational prospective study to describe neonatal Outcome according to the planned mode of delivery for term breech births in 2 such countries. Study design: Observational prospective study with an intent-to-treat analysis to compare the groups for which cesarean and vaginal deliveries were planned. Associations between the outcome and planned mode of delivery were controlled for confounding by multivariate analysis. The main outcome measure was a variable that combined fetal and neonatal mortality and severe neonatal morbidity. The study Population consisted of 8105 pregnant women delivering singleton fetuses in breech presentation at term in 138 French and 36 Belgian maternity units. Results: Cesarean delivery was planned for 5579 women (68.8%) and vaginal delivery for 2526 (31.2%). Of the women with planned vaginal deliveries, 1796 delivered vaginally (71.0%). The rate of the combined neonatal outcome measure was low in the overall population (1.59%; 95%, Cl [1.33-1.89]) and in the planned vaginal delivery group (1.60%; 95% CI [1.14-2.17]). It did not differ significantly between the planned vaginal and cesarean delivery groups (unadjusted odds ratio 1.10, 95% CI [0.75-1.61]), even after controlling for confounding variables (adjusted odds ratio 1.40, 95% CI [0.89-2.23]). Conclusion: In places where planned vaginal delivery is a common practice and when strict criteria are met before and during labor, planned vaginal delivery of singleton fetuses in breech presentation at term remains a safe option that can be offered to women.

In Parkinson's disease, altered activity in posterior associative cortices has often been associated with dementia. It remains to be determined if this pattern is a reliable marker of a progression toward dementia in patients without demonstratable dementia. In this retrospective analysis, we used positron emission tomography to study resting-state cerebral fluodeoxyglucose uptake in 8 healthy controls and 8 Parkinson's disease patients who did not have evidence of dementia at the time of assessment. For those patients, clinical follow up was available and we know that they did not meet dementia criteria on average 10,37 years after assessment. The results show that patients had reduced fluodeoxyglucose uptake mostly localised in the right hemisphere and including precuneus, superior temporal, middle temporal and inferior parietal cortices. It also includes right insula. These cerebral activity predominating in posterior cortices is present in non-demened patients but is not always predictive of dementia within the 10,34 years.

The paper reverse the famous question of Susan Möller Okin "Is multiculturalism bad for women" and asks the question of the supposed "natural alliance" between secularism and democracy. It takes as an illustration the relation between secularist movement and women's claims in the history of Belgium from the Belgian revolution until now. It presents a first, sketchy description of the alliance, trying to show that three periods can be distinguished : until the end of the schoolwar, the relations between the secularist movement and women's claim are rather weak and the secularists tend to distrust women, they consider as allied of the clerics; during the period of 1960-2000, the alliance is stonger over the claim of "self-disposal of one's body'" ; then, from 2000 until now, there is a strong division between both secularist and feminist movements, and so there are two alliances : radical secularism and mainstream feminist movement are allied against islam while, radical feminist and tolerant secularism are allied against neo-colonialist position.
