Probabilistic methods are emerging for operating electrical networks, driven by the integration of renewable generation. We present an algorithm that models a stochastic process as a Markov process using a multivariate Gaussian Mixture Model, as well as a model selection technique to search for the adequate Markov order and number of components. The main motivation is to sample future trajectories of these processes from their last available observations (i.e. measurements). An accurate model that can generate these synthetic trajectories is critical for applications such as security analysis or decision making based on lookahead models. The proposed approach is evaluated in a lookahead security analysis framework, i.e. by estimating the probability of future system states to respect operational constraints. The evaluation is performed using a 33-bus distribution test system, for power consumption and wind speed processes. Empirical results show that the GMM approach slightly outperforms an ARMA approach. [less ▲]

Despite the numerous studies on gay families, the current literature that has focused specifically on gay adoptive parent families remains rather limited. In Europe the laws on adoption by same-sex couples change radically from a country to another one. That’s why the experience of these families can be very different according to their country of residence. What are the main stressors that gay adoptive parents have to face? What are the strategies of coping built by these families? This exploratory research examines the stressors and the coping strategies of 18 gay adoptive families (12 from France, 6 from Belgium) with children aged from 3 to 10. Participants were recruited via adoption agencies. Belgian parents adopted their children through national full joint adoption. Conversely, French participants became parents through international adoption as “single parents” (even if they were in a relationship, just one of the partners was legally involved in the adoption). Semi-structured interviews were conducted with parents. Using grounded theory methods, analyses revealed that parents face different stressors such as the homophobia by social workers, the lack of support by families of origin and social context, the afraid of not being considered parents "like the others" and the worry about discrimination of their children. In the French sample, these stressors were increased by a long procedure in which the “legal parent” had to lie about his sexual orientation and the other parent had to hide himself in order to assure the success of the adoption procedure. This can have a negative impact on the couple's relationship, on the feeling of legitimacy about parental role, in the relationship with the child and with the extended family. To cope with these stressors, many adaptive strategies have proved to be useful: don’t hide the sexual orientation to the children, join adoption associations, share experiences with other gay parents, take care of the couple relationship, being in touch with accepting people and protect themselves from discriminatory people. This comparison between Belgian and French families’ experience allows us to understand the impact of the legal status on the life of gay parents and their children. [less ▲]

Belgium is one of the first European country to legalize marriage and adoption for same-sex couples (respectively in 2003 and 2006) and to state anti-discrimination laws (2008). Despite the legalization, what can we say about adults’ attitudes? This study is part of an international project, and aims at studying the attitudes towards different kind of same-sex constellations – single gays and lesbians, couples, and families – and at examining the correlates to those attitudes. Attitudes were assessed through self-report questionnaires in a cohort of 366 heterosexual participants resident in Belgium, 72% females and 28% males aged from 26 to 40 (age class corresponding to transition lifecycle and parenting choices). Participants were asked to answer socio-demographic questions and to self-report their contact with homosexual people (frequency and satisfaction). Then different scales assessed their attitudes toward homosexuality (General Attitudes Toward Homosexuality, Da Costa, 2011; ATLG, Herek), same-sex marriage (Katuzny Scale on Same-Sex Marriage, 2012) and different types of same¬-sex parenting – adoption, alternative insemination, in vitro, ovocyte donation (D’Amore & Green Homoparentality Scale, 2012). It is hypothesized that correlates to positive attitudes will be associated with female gender, lower religiosity, non-protestant religions, liberal political ideology, and higher education and socioeconomic status. This presentation contributes to a better understanding of Belgian’s attitudes toward same-sex couples and same-sex families, by measuring the predictive variables of positive and negative attitudes.

Indirect greenhouse gases and air quality at Northern Hemisphere mid-latitudes: long-term trends and variability derived from ground-based remote sensing at Jungfraujoch (Swiss Alps, 3580 m a.s.l.). We present an overview of recent investigations conducted by the Solar and Atmospheric Physics Infrared Group at the University of Liège and dedicated to the long-term monitoring of atmospheric gases with an indirect greenhouse effect and affecting air quality at Northern Hemisphere mid-latitudes. Gas concentrations are derived from high-resolution solar spectra recorded at the Jungfraujoch station (Swiss Alps, 46.5° N, 8.0° E, 3580 m a.s.l.), using Fourier transform infrared spectrometers. Time series obtained from these observations, along with satellite measurements and simulations from numerical models, allow for the study of both variability and recent evolution of these species and are critical for air quality monitoring and understanding climate changes.

Historians have long acknowledged the importance of the female spectator in actual, staged, tournaments, and literary critics have noted her intrinsic role in the tournaments of romance texts.In both cases, she functions as an inspiration to the male knight performing on the field, and as a means of constructing his masculinity.The potential agency of this female spectator who was able to look down on male bodies from a privileged viewing position has, however, been generally overlooked by art historians.This article uses the tournament context, in which women look at men (and vice versa), as a way of moving beyond the binary oppositions such as masculine/feminine, active/passive, that have traditionally structured discussions of gender and the gaze. By looking in particular at the imagery on carved ivory objects made for women, and their relationship to contemporary literature, I will argue for a more nuanced consideration of the ways women were able to look in the Middle Ages.

Streptococcus agalactiae, or group B streptococcus (GBS), remains the leading cause of neonatal sepsis and meningitis, early onset and late onset diseases (EOD, LOD). Where consensus guidelines to detect and treat intrapartum women with GBS colonization have been widely adopted, incidence of neonatal EOD has dramatically declined. In response to both successful impacts on the incidence of GBS-EOD and analyses of missed opportunities, the first American guidelines for prevention issued in the 90s have since been adapted in several stages to improve their efficacy. In some countries in Europe, nationwide guidelines, whether screening-based or risk-based, for the prevention of neonatal GBS diseases have also been issued and adopted, with the expected impact on incidence of GBS-EOD. In spite of universal screening, in spite of the great progress that has been made, GBS-EOD continues to occur and the GBS burden remains a significant public health issue. Continuous efforts to improve screening for GBS status continue to be important and may be able to take advantage of new rapid diagnostic technologies. The current screening-based strategy for prevention is highly effective but imperfect. Given the challenges, limitations and potential complications of maternal intrapartum prophylaxis, a new approach is still needed. Maternal immunization against GBS is an attractive alternative for the prevention of not only neonatal diseases but also stillbirths and maternal diseases. Vaccines against GBS may likely become the most effective and sustainable long-term preventive strategy. [less ▲]

In Europe, as in North America, GBS infections among infants are associated to high morbidity and mortality even if some differences exist between different European countries. During the past two decades, major initiatives have been proposed to prevent early onset GBS disease (EOD) and they are still subject of controversy. Several European countries have issued guidelines for the prevention of neonatal GBS diseases, either universal screening-based or risk-based strategy, others have no official guidelines at all. In countries having guidelines, despite considerable efforts and economic resources spent on intrapartum antimicrobial prophylaxis for GBS EOD, cases continue to occur. Among these cases there are a lot of missed opportunities to administer IAP but there are also false negative screening. Therefore in the setting of a maternal GBS-screening program and successful implementation of the strategy, efforts to improve screening for GBS status remain important. The natural reservoir for GBS is the gastrointestinal tract and is likely the source for vaginal colonization. Among pregnant women, GBS carriage rate in the vaginal and rectal flora ranges from 10% up to 30%. Critical factors that influence the accuracy of detecting GBS maternal colonization are the choice of the body sites sampled, the timing of sampling and the use of selective culture media. The evolution of the different culture options to improve the GBS-screening strategy will be reviewed. If the optimal time for performing antenatal cultures is between 35 to 37 weeks’ gestation, as GBS carriage is highly variable, the predictive values of GBS antenatal cultures are not always as good predictors of the maternal GBS status at presentation for delivery as expected. Potential alternative to antenatal GBS-screening culture is the identification of GBS colonization at presentation for delivery. Use of a reliable, sensitive, easy to use rapid test should be cost effective leading to the prevention of more EOGBS cases while reducing the number of unnecessarily IAP. Advances of polymerase chain reaction (PCR) and fluorescence labeling technologies has provided new detection tools for bacterial identification. Therefore, commercialization of rapid detection of GBS through real-time PCR offers the potential for GBS detection among women without prenatal care or those in whom no antenatal culture was collected. However questions of costs and logistics remain unanswered. Could such rapid intrapartum test replace existing screening strategies or could it be used in conjunction with them? Colonizing rates and recommended screening procedures existing through Europe will be reviewed. [less ▲]

Development of a group B streptococcal vaccine (GBS) vaccine is the most promising approach for the prevention of GBS infections in babies, given the potential adverse effects of intrapartum antibiotic prophylaxis as well as the need for effective prevention of both adult and late perinatal disease. There are numerous prevention strategies at this time but none are 100% effective in the eradication of neonatal early onset GBS disease and there are no preventative strategies for late onset disease. The need for a GBS vaccine is therefore, of utmost importance. Efforts applying genomics to GBS vaccine development have led to the identification of novel vaccine candidates. The publication of GBS whole genomes coupled with new technologies including multigenome screening and bioinformatics has also allowed researchers to overcome the serotype limitation of earlier vaccine preparations in the search of a universal effective vac- cine against GBS. This review brings together the key arguments concerning the potential need of a GBS vaccine in developed countries and describes the current status with GBS epidemiology and microbiology in these countries [less ▲]
