Medically refractory chronic cluster headache (CH) is a severely disabling headache condition for which several surgical procedures have been proposed as a prophylactic treatment. None of them have been evaluated in controlled conditions, only open studies and case series being available. Destructive procedures (radiofrequency lesioning, radiosurgery, section) and microvascular decompression of the trigeminal nerve or the sphenopalatine ganglion (SPG) have induced short-term improvement which did not maintain on long term in most of the patients. They carried a high risk of complications, including severe sensory loss and neuropathic pain, and consequently should not be proposed in first intention.Deep brain stimulation (DBS), targeting the presumed CH generator in the retro-hypothalamic region or fibers connecting it, decreased the attack frequency >50 in 60 % of the 52 patients reported. Complications were infrequent: gaze disturbances, autonomic disturbances, and intracranial hemorrhage (2).Occipital nerve stimulation (ONS) was efficient (decrease of attack frequency >50 %) in about 70 % of the 60 patients reported, with a low risk of complications (essentially hardware related). Considering their respective risks, ONS should be proposed first and DBS only in case of ONS failure.New on-demand chronically implanted SPG stimulation seemed to be efficient to abort CH attacks in a pilot controlled trial, but its long-term safety needs to be further studied.

The Viséan ‘black marble’ of Denée is one of the best preserved Mississippian fossil assemblages. This Lagerstätte is famous for the exceptional preservation of several groups of macro-organisms (fishes, echinoids, graptolites). However, only a part of the fauna has received attention from specialists and most of the phyla may benefit from a modern revision based on new investigative techniques such as 3D imagery and CT-scanning. Almost all the specimens illustrated in the literature have been traced and we present here a comprehensive catalogue of this material. Representatives of several minor groups are photographically illustrated for the first time as well as five emblematic specimens of the styracopterid genus Benedenius (Pisces). For purposes of nomenclatural formality, the lectotypes of Benedenius deneensis Traquair (in de Koninck, 1878), B. soreili Fraipont, 1890, Oligoporus soreili Fraipont, 1904, Taeniaster? fournieri Fraipont, 1904, and Scaphiocrinus longicaudatus Fraipont, 1904 are here selected.

Sex steroid hormones act on developing neural circuits regulating the hypothalamic-pituitary-gonadal axis and are involved in hormone-sensitive behaviours. These hormones act mainly via nuclear receptors, i.e. oestrogen receptor-alpha (ERalpha) and androgen receptor (AR). By using immunohistochemistry, we analysed the expression level of ERalpha and AR throughout perinatal life [at embryonic (E) day 19 and postnatal (P) days 5-15-25] and in adulthood in several hypothalamic nuclei controlling reproduction in both wild-type (WT) and aromatase knockout (ArKO) (which cannot convert testosterone into oestradiol) mice to determine whether there are sex differences in hypothalamic ERalpha and AR expression and if so, whether these are established by oestradiol action. As early as E19, ERalpha immunoreactivity (-ir) was observed at same expression levels in both sexes in the anteroventral periventricular nucleus (AVPv), the medial preoptic area (MPOA), the bed nucleus of the stria terminalis (BnST), the ventrolateral part of the ventromedial hypothalamic nucleus (VMHvl) and the arcuate nucleus (ARC). Sex differences (female > male) in ERalpha-ir were only observed during the prepubertal period in the BnST (P5 to P25) and the MPOA (P15), but also in adulthood in these two brain regions. Sex differences in AR-ir (male > female) were observed at P5 in the AVPv and ARC, and at P25 in the MPOA and ARC as well as in adulthood in all hypothalamic regions analysed. In adulthood, gonadectomy and hormonal treatment (oestradiol or dihydrotestosterone) also strongly modulated ERalpha-ir and AR, respectively. Taken together, sex differences in ERalpha-ir and AR-ir were observed in all hypothalamic regions analysed, but most likely do not reflect oestradiol actions since ArKO mice of both sexes showed very similar expression levels as WT mice throughout perinatal development.

Following the introduction in the 80's of the invasive coccinellid species Harmonia axyridis (Pallas) in Europe, several studies have begun to focus on the interactions with other aphid predator species. In this study, aphids and associated predators were sampled to determine their relative abundance in four agricultural crops (broad bean, corn, potato, and wheat) in Belgium during 2010 and 2011. The Moericke trap was used to quantify the mean number of aphids and aphid predators from May to September in both years. A total of 28 aphid species and 21 aphidophagous species were observed. In both years, H. axyridis was among the most abundant aphidophagous predators in all four crops, and was the second most abundant coccinellid species after Coccinella septempunctata L. The community of aphidophagous species was similar across all four inventoried crops. However, the highest population densities of this alien species were recorded in broad bean and potato crops, which also hosted the highest aphid population densities. In conclusion, this study demonstrates that the communities of aphid predators are highly diversified in the agroecosystems, despite the high occurrence of H. axyridis, an introduced predator that has become well established in this environment.

Most of the existing criticism on Caryl Phillips deals with his novels or his essays. His plays, which were for the most part written in the 1980s, have received comparatively little attention. This article argues that Phillips’s dramatic production should be examined closely because it contains in a nutshell some of the themes and characters that recur in his more mature work and therefore form the backbone of his world vision. Such a comparative approach helps to highlight Phillips’s artistic consistency and his ability to give different forms to similar concerns. More specifically, its aim is to show to what extent Phillips’s novel In the Falling Snow (2009) is a liminal text that is in fact built upon the preoccupations at the heart of his early plays, most notably Strange Fruit (1981), Where There Is Darkness (1982) and The Shelter (1983).

Since the appearance of Internet, several preoccupations have appeared as a result, with Internet addiction being one of the most common. The goals of the present study were two-fold. First, to examine which psychological factors are relevant to explain Internet addiction, including impulsivity, passion and social provision. Second, to incorporate all these factors into an integrative model. Based on multiple regressions and path analysis, results revealed a positive relation between Internet addiction and specific impulsivity components (lack of perseverance, urgency) and obsessive passion. Moreover, positive relations were observed between obsessive passion and reassurance of worth, opportunity for nurturance, sensation seeking and harmonious passion. In other words, Internet addiction is related to obsessive passion, but is explained by different psychological factors. Accordingly, both Internet addiction and obsessive passion can be viewed as two important and complementary facets of problematic Internet use. [less ▲]

Monitoring tropical forest carbon stocks changes has been a rising topic in the recent years as a result of REDD+ mechanisms negotiations. Such monitoring will be mandatory for each country willing to benefit from these financial incentives in the future. Aerial and satellite remote sensing technologies offer cost advantages in implementing large scale forest inventories. Despite the recent progress made in the use of airborne LiDAR for C stocks estimation, no widely operational and cost effective method has yet been delivered for central Africa forest monitoring. Within the Maï Ndombe region of DRC, the EO4REDD project develops a method combining satellite, aerial and ground measurements. This combination is done in three steps: [1] mapping and quantifying forest cover changes using an object-based semi-automatic change detection (deforestation and forest degradation) methodology based on very high resolution satellite imagery (RapidEye), [2] developing an allometric linear model for above ground biomass measurements based on dendrometric parameters (tree crown areas and heights) extracted from airborne stereoscopic image pairs and calibrated using ground measurements of individual trees on a data set of 18 one hectare plots and [3] relating these two products to assess carbon stocks changes at a regional scale. Given the high accuracies obtained in [1] (> 80% for deforestation and 77% for forest degradation) and the suitable, but still to be improved with a larger calibrating sample, model (R2 of 0.7) obtained in [2], EO4REDD products can be seen as a valid and replicable option for carbon stocks monitoring in tropical forests. Further improvements are planned to strengthen the cost effectiveness value/REDD+ suitability in the 2nd phase of EO4REDD. This 2nd phase will include [A] specific model developments per forest type; [B] measurements of afforestation, reforestation and natural regeneration processes and [C] study of Sentinel data series potential use.

Emanating from different areas of the human sciences, repetition was given a central role in this thesis of semiotic inclination. It is a widespread phenomenon in all fields of human activity and, particularly, in texts. The optional character of certain repetitions in texts brings about the problem of its function, since, in certain cases, it seems to act directly on the rhythm of the content and the flow of entrances and exits of the phenomenal field. This regulation of the rhythm divides the research into two fronts. On the one hand, the rhythmic effect points to an underlying structure. In that sense, one can ask: what is the configuration of such structure? In what way is repetition part of it? Or even, what is its place in the semiotic model? On the other hand, repetition seems to involve a certain degree of contradiction: in what way can a phenomenon that brings no novelty, only the resumption of the same, sometimes create an effect of tension or surprise? In order to answer these questions, we undertake the revision of the role of repetition in neighboring fields: rhetoric and a specific trend in linguistics. This discussion has allowed us to detect a few insufficiencies in these approaches that may be answered by semiotics. From the semiotic perspective, we have explored the place occupied by repetition, by opposing it to concepts such as identification, text, language and to the notion of semiotics itself. Once the position of repetition in the text is established, we move on to note and discuss the textual conditions necessary to the occurrence of relevant repetitions. In addition to identification, the notion of salience, based on the opposition between figure and ground, revealed itself to be central to the explanation of the phenomenon. Finally, linearity has also proven relevant, which allowed us to re-discuss its theoretical status as one possible manifestation of the underlying syntagmatic structure. Having outlined the conditions for repetition, we have started an investigation into the somewhat contradictory effects we had observed in repetitive incidents. We saw that repetition belongs to the order of extent – it is counted, not measured – and, in being so, it is a tool for the manifestation of the rhythm of the content that is presupposed by it. In these terms, repetition is subordinated to the intensive sub-dimensions: tempo and tonicity. To ensure the relevance of our arguments, we studied repetition within some selected objects, where it is made to serve of the text. Finally, the analysis of these objects shed light on the relations between repetition and the concept of aspect, and three styles of textual progression related to repetition were confirmed: circular, linear and spiraling. This path of investigation has shown us the terms which repetition is tied to and the way in which it manifests an underlying structure. It has also revealed that such structure not only explains but also generates the variations in rhythm and tempo that are felt through repetition. The apparent contradictions of the effects of repetition are explained by the very epistemological bases of the field. The analytical and relational aspects of semiotics are the basis for repetitive construction, which, without adding any new information, may lead the enunciatee to tension, climax and surprise.

Using an international database featuring 1624 mutual funds over 15 years, this paper analyses the joint abilities of performance measures to predict subsequent fund failure. We examine the probability of disappearance over a time window, and expected fund survival time, and study the circumstances of a fund’s disappearance, its currency and domicile. By combining relevant measures, fund failure appears to a significant extent predictable, more than with single classical measures. Survivorship predictability has significant economic value. Such evidence suggests that past performance does not only influence investors’ perception of fund quality, but also reflects managers’ ability to sustain performance. [less ▲]
