Since almost three decades, luxury houses have been tackling the increasing importance of groups and of private investment funds specialized in the luxury sector (Roux & Floch, 1996). Therefore innovation has become an important source of value creation and of competitive advantage for them (Chevallier & Mazzalovo, 2008; Kapferer & Bastien, 2009). Reciprocally, luxury houses usually demonstrate a strong intellectual capital according to the definitions of Bontis (1998). Although the impact of intellectual capital on innovation has been widely demonstrated by scholars in a general scope (Subramaniam & Youndt, 2005), the existence and the nature of this influence has not been investigated in the luxury sector yet. The aim of our research is to highlight if a causal relationship exists in Belgian luxury houses, in order to validate or invalidate the results obtained by Subramaniam & Youndt (2005) and by Wu, Chang, & Chen (2008) within the luxury sector.

The “Belle Epoque” saw the revival of the colonial idea in new forms. A second European colonization wave washed over Africa. King Leopold II unfolded his activities in Congo from 1876 onwards. There, his efforts to develop a so-called “philanthropic” enterprise soon evolved in a process of state formation, overshadowed by intrigues and tensions that were a consequence of colonial competition between the western powers. Only a decade later, at the Berlin Conference of 1885, a definite arrangement was adopted. Everywhere in Europe, a disputed transition was made from liberal to more conservative ways of government. Of course this tension field also dominated intellectual life. There was an intense debate between partisans of colonialism and supporters of worldwide free trade. For the development of his colonial doctrine Leopold II had been inspired by intellectuals that supported economic expansionism. Most of them were active in the field of economic geography. But the King also searched for support in other academic circles and mobilized one of Europe’s brightest minds to join him in his quest for the most adequate economic, social and political model of a future state in the heart of Africa. In his books, articles and pamphlets, the liberal minded political economist Emile de Laveleye (1822-1892) – an opinion maker of European renown – showed himself an unshakable opponent of colonization and imperialism. However, in the period 1875-1885 – a decade so crucial for Congo – a surprising intellectual rapprochement between de Laveleye and Leopold II was established. For a certain time, this competent man of science advised the King, for example at the International Geographical Conference in Brussels, putting into royal service an intellectual network of European range. This paper investigates how, in the complex and constantly evolving public discussion about Congo, two apparently opposing minds attracted each other. Analyzing de Laveleye’s publications and correspondence we focus on his important pleas for a “neutral and international formula” that would place Leopold II in a conflicting situation with Portugal and France, countries that claimed Congo’s estuary for their own benefit. De Laveleye believed that Leopold was sincere about his civilizing mission and crusade against slavery. This study shows how, in the years preceding the Berlin Conference, de Laveleye got actively involved in a carefully orchestrated European media campaign in support of Leopold’s initiative. It was there that his intellectual circle became extremely useful and was fully implicated. His contacts in the world of law, especially among experts of international law, contributed to the important discussions about Congo’s juridical status. De Laveleye’s colleague Sir Travers Twiss, one of the most reputed jurists of that time, as well as the influential Institut de Droit international, of which de Laveleye had been one of the founders, entered the debate zone and took positions that were favorable for Leopold’s project. With this new approach, our paper also aims to give insight in the way Leopold II transformed his own reasoning into a more authoritative set of practical standards that were shared by an intellectual elite.

Located close to the feet of the magnetic field lines connecting Io to each Jovian hemisphere, the Io footprint is the auroral signature of the electromagnetic interaction between Io and Jupiter's magnetosphere. It consists of several spots followed downstream by an extended tail. The size of the main spot is expected to scale to the size of the interaction region close to Io. Consequently, this quantity is crucial to understand the processes involved. However, the main spot size is a controversial issue as previously published values range from ~400 km to ~10000 km, leading to contradictory conclusions. Based on observations carried on with the Hubble Space Telescope STIS and ACS FUV instruments from 1997 to 2009, we estimate the size of the main footprint spot on a much larger image sample than previously. Additionally, we carefully selected the images in order to avoid viewing geometry ambiguities when measuring the spatial extent of the different features. The main spot length along the footpath is ~900 km while its width perpendicular to the footpath is <200 km. The spot length is larger than the projected diameter of Io along unperturbed magnetic field lines, which appears to be consistent with recent simulations. The vertical extent and the peak altitude of the main spot are similar to those measured in the tail. Nevertheless, the secondary spot attributed to trans-hemispheric electron beams has been measured to peak at ∼200 km below the main spot and the tail, which confirms their different origins.

Using data from a clinical psychoanalytic study of lesbian couples undertaking Artificial Insemination by Donor (AID), the conference explores how female same sex parenting is related to the notion of the third and to the concept of bisexuality by focusing on two specific themes: the position attributed to the donor, who is unknown to the lesbian parents, as well as the process of evolution and attribution of the place of each mother in the lesbian couple. Our aim is to highlight the complexity of the issue of the third in same-sex parenting by analysing fantasised constructions surrounding the image of the anonymous donor, the impact of the medical act of insemination on the women’s psychic economy and the search for other promising bases for triangulation. We would also like to demonstrate the complexity of the issue of bisexuality: although the project of having a child mobilizes a wide range of identifications for both parental imagos, the whole procedure leading to AID shakes up omnipotent sexual fantasies, mobilizes the fantasy of the heterosexual primal scene and makes necessary further elaboration of the feminine side of bisexuality in the context of gender differences.

Purpose: Aggregated results of systematic reviews separately show how light used as a treatment and some occupational therapy interventions could have a positive impact on psychobehavioural disorders in older people. Since the beginning of June 2014 the Walloon Government has been financing a project which consists of a non-pharmacological approach that combines light and occupational therapy for a psychogeriatric population with specific symptoms: spatial and temporal disorientations, apathy, depression, agitation, anxiety, confusion and circadian disorder. The objective of this abstract is to expose the assumptions that the combination of two different light devices and one specific occupational therapy program could have an impact on the different symptoms of a psychogeriatric population. Methods: To build our hypothesis, two literature reviews have been achieved. The first one concerning the use of light as therapy gathered 30 studies while the other one about occupational therapy activities collected 35 articles. Results: Despite of a heterogeneity between studies dealing with light and occupational therapy, the combination of these two non-pharmacological interventions might fight the depressive syndrome, reduce the temporal disorientation thanks to a regularity in the period of activity, restore the circadian rhythm and so reduce some troubles that can be linked to them: sleep disorder, risk of fall, apathy, agitation, behavioural and cognitive troubles (attention, concentration). Moreover, one of the two light devices used which can modulate the light intensity according to the rooms might reduce the spatial disorientation if it’s employed as a landmark. Conclusions: Based on literature reviews and our experience into this field it’s seems that a non-pharmacological approach involving light and occupational therapy intervention could have a positive effect on symptoms of psychogeriatric population. In admitting that those effects are becoming true after experimentation and analyses, we can also expect an improvement of the quality of life. [less ▲]

Mannheimia haemolytica induced pneumonias are only observed in goats, sheep and cattle. The bacterium produces several virulence factors,whose principal ones are lipopolysaccharide and leukotoxin. The latter is cytotoxic only for ruminant leukocytes, a phenomenon that is correlated with its ability to bind and interact with the ruminant beta2-integrin Lymphocyte Function-associated Antigen 1. This paper globally reviews all the information available on host-pathogen interactions underlying respiratory mannheimiosis (formerly pasteurellosis), from the stable and the Petri dish to the biochemical cascade of events triggered by the leukotoxin inside ruminant leukocytes. One conclusion can be made: the most widespread cattle respiratory disease with the most important impact on beef production worldwide, is probably due to a tiny ruminant-specific focal variation in the CD18- and/or CD11a-expressing genes.

The common hippopotamus (Hippopotamus amphibius L.) is part of the animal species endangered because of multiple human pressures. Monitoring of species for conservation is then essential, and the development of census protocols has to be chased. UAV technology is considering as one of the new perspectives for wildlife survey. Indeed, this technique has many advantages but its main drawback is the generation of a huge amount of data to handle. This study aims at developing an algorithm for automatic count of hippos, by exploiting thermal infrared aerial images acquired from UAV. This attempt is the first known for automatic detection of this species. Images taken at several flight heights can be used as inputs of the algorithm, ranging from 38 to 155 meters above ground level. A Graphical User Interface has been created in order to facilitate the use of the application. Three categories of animals have been defined following their position in water. The mean error of automatic counts compared with manual delineations is +2.3% and shows that the estimation is unbiased. Those results show great perspectives for the use of the algorithm in populations monitoring after some technical improvements and the elaboration of statistically robust inventories protocols.

Black rats are among the major invasive vertebrates with severe ecological, economic and health impacts. Remarkably, the evolutionary history of black rats has received little attention and there is no firm agreement as how many species should be recognized within the Rattus rattus complex. Members of the species complex are native from India and Southeast Asia. Current taxonomy suggests that four taxa live in sympatry in several places of Thailand and Cambodia where the present study was conducted: three accepted species (R. tanezumi, R. losea, R. argentiventer) and an additional lineage of unclear taxonomic status sometimes referred as Rattus R3. We used an extensive sampling, morphological data and diverse genetic markers of different evolutionary rates and parental inheritance (two mtDNA genes, one nuclear gene and eight microsatellite loci) to assess the genetic structure among the four taxa. Genetic analyses revealed discordant patterns between the mt and the nuclear data. The mt phylogeny identified three reciprocally monophyletic clades corresponding to the four putative taxa while the nuclear phylogeny failed to separate tanezumi and R3. Within geographic localities, microsatellites revealed free gene flow between tanezumi and R3 but no gene flow between those two taxa and losea or argentiventer. Altogether theses analyses do not support the taxon R3 as a valid species and advocate for synonymy with tanezumi. As a consequence, R. tanezumi becomes paraphyletic with respect to losea. Simulation analyses are now ongoing to determine whether a recent speciation event between tanezumi and losea, or an incomplete lineage sorting within tanezumi could explain this uncommon pattern.

Background: In Belgium as in many Western countries, GBS are still the leading cause of severe perinatal infections. Current guidelines for prevention recommend intrapartum antimicrobial prohylaxis (IAP) administered promptly before delivery to pregnant women colonized with GBS. The risk of vertical GBS transmission to the newborn decreases as the duration of prophylaxis increases. The considered threshold for prophylaxis adequacy is the first dose administered at least 4 hours before delivery. Objective: To evaluate the proportion of pregnant women who could benefit from an adequate IAP for the prevention of GBS perinatal infections. Methods: Between June and October 2003, we recorded in two hospitals the elapse time between admission for labor and delivery. We assumed 5 hours represent a useful threshold to allow admission, revision of chart and administration of adequate IAP. The status of vaginal colonization with GBS was determined by CDC’s recommended culture method with Granada agar added. Results: Among 532 women, 27.3 % delivered within 5 hours after admission for labor. The colonization rate for GBS was 25.6 %. The distribution of elapse time between admission and delivery for GBS colonized pregnant women was not significantly different from non colonized women (p <= 1). Conclusions: 1) With the current prevention strategy, 27.3 % of these pregnant women would not have benefit from adequate prophylaxis 2) These results highlight the importance of an efficient organization to warranty prompt administration of IAP as soon as possible when mandatory. 3) If a rapid intrapartum screening test is used, no delay can be afforded “from ward to bench to bed”.
