In recent years, party autonomy has conquered new grounds in cross-border private relationships. Building on first attempts in national codifications, party autonomy has become one of the leading principles used in various EU regulations dealing with cross-border family relationships. It can now be found in successions, in divorce, in maintenance matters. This new trend has been greeted sometimes with enthusiasm, sometimes with skepticism. While these Regulations constrain the choice that parties can make, it cannot be denied that the principle of freedom of choice has been openly embraced by the European legislator. Hence this principle evolved, at least within the EU, from what was until recently a marginal phenomenon to a well-respected solution for cross-border family relationships This (r-)evolution occurred quite fast and has attracted much attention. However, much of the research in this area has adopted a limited perspective, focusing exclusively on the possibilities and limits of choice in one specific instrument or adopting a comprehensive outlook but with a strong positive flavor. While it is true that a number of contributions provide excellent food for thought, the overall impression is that more time and more research is needed to start apprehending the fundamental questions raised by this evolution. At this stage, it may be too early to offer a comprehensive study of all questions raised by party autonomy in private international law. New developments may in fact modify the picture soon and add to the fields conquered by party autonomy. At the same time, the relative novelty of the changes makes it difficult to take full stock of all issues raised by the development of party autonomy. This is why scholars should first attempt to define a research agenda. This paper offers a first scratch by exploring various questions which should figure prominently in such agenda. It is by no means meant to be exhaustive. Rather, an attempt will be made to shed some light on the main questions raised by recent evolution in the hope of being an invitation for further research.

In the framework of the CROSTVOC (CROp STress VOC) project, the exchange of biogenic volatile organic compounds (BVOCs) between two important agricultural crop species, maize and winter wheat, and the atmosphere has recently been measured during an entire growing season by using the eddy covariance technique. Because of the co-variation of BVOC emission drivers in field conditions, laboratory studies were initiated in an environmental chamber in order to disentangle the responses of the emissions to variations of the individual environmental parameters (such as PPFD and temperature) and to diverse abiotic stress factors. Young plants were enclosed in transparent all-Teflon dynamic enclosures (cuvettes) through which BVOC-free and RH-controlled air was sent. BVOC enriched air was subsequently sampled from the plant cuvettes and an empty cuvette (background) and analyzed for BVOCs in a high sensitivity Proton-Transfer Reaction Mass Spectrometer (hs-PTR-MS) and for CO2 in a LI-7000 non-dispersive IR gas analyzer. Emissions were monitored at constant temperature (25 °C) and at a stepwise varying PPFD pattern (0-650 µmol m-2 s-1). For maize plants, sudden light/dark transitions at the end of the photoperiod were accompanied by prompt and considerable increases in methanol (m/z 33) and water vapor (m/z 39) emissions. Moreover, guttation droplets appeared on the sides and the tips of the leaves within a few minutes after light/dark transition. Therefore the assumption has been raised that methanol is also coming out with guttation fluid from the leaves. Consequently, guttation fluid was collected from young maize and wheat plants, injected in an empty enclosure and sampled by PTR-MS. Methanol and a large number of other compounds were observed from guttation fluid. Recent studies have shown that guttation from agricultural crops frequently occurs in field conditions. Further research is required to find out the source strength of methanol emissions by this guttation phenomenon in real environmental conditions. [less ▲]

We present a new procedure for wood sampling and tree-ring measurement that can be used for dendrochronological investigation on very large trees, specifically adapted for tropical rainforest species. This procedure takes advantage of the technological developments in computing, image processing, and geographic information systems (GIS) to overcome the technical limitations of the currently used methods. Two types of wood samples can be used (stem disks and/or bars) depending on tree diameter, and the difficulty of ring delineation and crossdating. Bars are an effective compromise between cores and disks. We developed an application combining several programs (Excel, R, ArcGIS, and MapWinGIS) in the Windows operating system for semi-automatic measurement of tree-rings from high-resolution images of the sanded cross-section. Using an innovative method to reverse the wood shrinkage resulting from the drying process, tree-ring measurement can be performed on shrinkage-free images, thus referring to the actual growth of the tree.

Recent years have seen the rise of middleboxes, such as firewalls, NATs, proxies, or Deep Packet Inspectors. Those middleboxes play an important role in today's Internet, including enterprise networks and cellular networks. However, despite their huge success in modern network architecture, they have a negative impact on the Internet evolution as they can slow down the TCP protocol evolution and its extensions. Making available a summary of the potential middlebox network interferences is of the highest importance as it could allow researchers to confront their new transport protocol to potential issues caused by middleboxes. And, consequently, allowing again innovation in the Internet. This is exactly what we tackle in this paper. We propose a path impairment oriented middlebox taxonomy that aims at categorizing the initial purpose of a middlebox policy as well as its potential unexpected complications. Based on a measurement campaign on IPv4 and IPv6 networks, we confront our taxonomy to the real world. Our dataset is freely available. [less ▲]

Background: Long-term exposure to persistent pollutants with hormonal properties (endocrine-disrupting chemicals, EDCs) may contribute to the risk of prostate cancer (PCa). However, epidemiological evidence remains limited. Objectives: We investigated the relationship between PCa and plasma concentrations of universally widespread pollutants, in particular p,p’- dichlorodiphenyl dichloroethene (DDE) and the non-dioxin like polychlorinated biphenyl congener 153 (PCB153). Methods and Findings: We evaluated before treatment 576 men with newly diagnosed PCa and 655 controls in Guadeloupe (French West Indies). Exposure was analyzed according to case-control status. Associations were assessed by unconditional logistic regression analysis, controlling for confounding factors. Missing data were handled by multiple imputation. We estimated a significant positive association between DDE and PCa (adjusted odds ratio [OR] 1.53; 95% CI 1.02, 2.30 for the highest versus lowest quintile of exposure; PTrend= 0.01). PCB153 was inversely associated with PCa (OR 0.30; 95% CI 0.19, 0.47 for the highest versus lowest quintile of exposure values; PTrend<0.001). Also, PCB153 was more strongly associated to low-grade than high grade PCa. Conclusions: Associations of PCa with DDE and PCB153 were in opposite directions. This may reflect differences in the mechanisms of action of these EDCs, and although our findings need to be replicated in other populations, they are consistent with complex effects of EDCs on human health.

La Passion de sainte Salsa, jeune chrétienne de Tipasa martyrisée pour avoir décapité une statue du dieu Draco, est restée longtemps dans l’oubli. Cette passion “épique” ou plutôt “romanesque”, datée ici des premières décennies du Ve siècle, offre pourtant un témoignage exceptionnel sur le niveau culturel de la Maurétanie Césarienne à la veille ou au moment de l’invasion vandale. L’hagiographe, doté d’un talent rare, pratique une prose d’art, maniériste et poétique, caractérisée par le mélange des genres tardif et par le “style de joaillerie”. On trouvera dans ce volume une nouvelle édition critique du texte avec une traduction annotée et une série d’articles qui étudient les restes archéologiques du culte de Salsa à Tipasa et abordent tous les aspects littéraires de l’œuvre en la comparant notamment aux Passions contemporaines de Marciana et de Fabius, qui ont souvent été attribuées au même auteur.

Molecular assessment of a large portion of traditional cyanobacterial taxa has been hindered by the failure to isolate and grow them in culture. In this study, we developed an optimized protocol for single cell/filament isolation and 16S rRNA gene sequencing of terrestrial cyanobacteria with large mucilaginous sheaths, and applied it to determine the phylogenetic position of typical members of the genera Petalonema and Stigonema. A methodology based on a glass-capillary isolation technique and a semi-nested PCR protocol enabled reliable sequencing of the 16S rRNA gene from all samples analyzed. Ten samples covering seven species of Stigonema from Europe, North and Central America, and Hawaii, and the type species of Petalonema from Slovakia were sequenced. Contrary to some previous studies, which proposed a relationship with heteropolar nostocalean cyanobacteria, Petalonema appeared to belong to the family Scytonemataceae. Analysis of Stigonema specimens recovered a unique coherent phylogenetic cluster, substantially broadening our knowledge of the molecular diversity within this genus. Neither the uni- to biseriate species nor the multiseriate species formed monophyletic subclusters within the genus. Typical multiseriate species of Stigonema clustered in a phylogenetic branch derived from uni- to biseriate S. ocellatum Thuret ex Bornet & Flahault in our analysis, suggesting that species with more complex thalli may have evolved from the more simple ones. We propose the technique tested in this study as a promising tool for a future revision of the molecular taxonomy in cyanobacteria. [less ▲]
