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”.

In MIND subtask 3.2, we ascertain whether and how microbes, microbiologists, and microbiology are enrolled into research on the geological disposal of radioactive waste. We adopt a social studies of science (actor-network theory) perspective that observes how actors within MIND (e.g. MIND researchers, members of the MIND Implementer Review Board) and outside the project (e.g. geologists, waste management regulators, policy makers) process data and generate insights on the role of microbes in waste disposal, and how these processes elicit challenges and opportunities for enrolment. Examples of the latter include mixed appreciations of the impact of microbial activity on artificial barriers (e.g. negligible vs. substantial), the scope for, and appeal of, institutional uptake of microbiology research (e.g. through the coupling of microbiology research to “the safety case”), and the (re)drawing of disciplinary boundaries (e.g. between microbiology and geology). Drawing on these and related examples, we explore how through projects like MIND, microbes network, and are networked, differently for the joint purpose of radioactive waste disposal. [less ▲]

The purpose of this study is to assess whether competition agencies (“CAs”) do, and in turn should, enjoy an unfettered discretionary power in the context of the investigation of competition law infringements or whether their margin of discretion should be subject to certain limits. To this end, it focuses on four successive areas where CAs may be entitled to make choices, i.e. detection of infringements, selection of enforcement targets, initiation of infringement proceedings and outcome of the case. Thanks to reports received from 21 national experts in response to a questionnaire covering 18 jurisdictions, the present study formulates a number of public policy proposals. [less ▲]

Purpose: The Dallas Pain Questionnaire (DPQ) assesses the impact of low back pain (LBP) on four components (0–100) of daily life. We estimated the minimal clinically important improvement (MCII) and the patient acceptable symptom state (PASS) values of DPQ in LBP patients. Methods: 142 patients with LBP lasting for at least 4 weeks completed a battery of questionnaires at baseline and 6 months later. Questions for MCII addressed patientreported response to treatment at 6 months on a five-point Likert scale, while a yes/no question concerning satisfaction with present state was used to determine PASS. MCII wascomputed as the difference in mean DPQ scores between patients reporting treatment as effective vs. patients reporting treatment as not effective, and PASS was computed as the third quartile of the DPQ score among patients who reported being satisfied with their present state. Results: MCII values were 22, 23, 2 and 10 for daily activities, work and leisure, social interest, and anxiety/depression, respectively. PASS values were 29, 23, 20 and 21 for the four components, respectively. The PASS total score threshold of 24 correctly classified 84.1 % of the patients who reported being unsatisfied with their present state, and 74.7 % of patients reported being satisfied. Conclusions: These values give information of paramount importance for clinicians in interpreting change in DPQ values over time. Authors should be encouraged to report the percentage of patients who reach MCII and PASS values in randomized clinical trials and cohort studies to help clinicians to interpret clinical results.

Le traitement conservateur est une constante dans l’approche oncologique. Des efforts ont été développés afin de conserver au maximum l’intégrité de la fonction et/ou de l’image corporelle. Ce souci de sauvegarde se traduit par des approches thérapeutiques non mutilantes: un exemple typique est le changement de paradigme thérapeutique au moment de l’introduction de la chirurgie conservatrice de la glande mammaire en lieu et place de la mastectomie. Ce concept de chirurgie non radicale a été possible grâce à l’association avec la radiothérapie externe postopératoire. Des essais randomisés ont permis de valider le concept et de démontrer que le risque de rechute loco-régionale et ultérieurement la survie ne sont pas modifiés comparés à une approche chirurgicale potentiellement délabrante. Ces essais randomisés ne se sont fort heureusement pas limités aux aspects purement oncologiques. De façon prospective on a pu déterminer l’excellence des résultats cosmétiques à moyen et à long terme. Il est vrai que cette approche par essais randomisés était un passage indispensable et a permis de valider ce concept thérapeutique. Il aurait été pour le moins étonnant de prôner d’emblée une approche chirurgicale non mutilante mais oncologiquement complète, si à terme le résultat esthétique aurait été inférieur à celui que l’on aurait pu escompter après mastectomie radicale suivie de reconstruction.

Introduction With the stop jump, the counter movement jump (CMJ) is probably the most used jump in sport. In the literature, a number of studies use the counter movement jump to explore (neuro-)muscular fatigability [1-4]. However, due to the continuous [1-3] (or semi-continuous [4]) character of the test, the CMJ become drop jumps from the second one. Nevertheless, the drop jump isn't the most frequent jump type in sport. These evaluations, with (semi-)continuous jumps, don't reflect the sport reality and therefore a more effective (neuro-)muscular jumping fatigability evaluation must be validated. Methods Nineteen volleyball players (23,5 ± 3,3 years, 187,6 ± 6,6 cm, 77,5 ± 8,5 kg), with no history of (major) lower limb injury, submitted to two jumping fatigability tests, with seven days between each session, under the direction of a single researcher. The jumping fatigability tests consists of the repetition of 50 maximal CMJ at the rate of 33bpm. Between each CMJ, the subject were asked to make a full triple-extension and to wait the next auditory and visual signal of the metronome to start the hip-knee-ankle flexion. With these instructions, each jump remains a CMJ. Subjects were asked to leap as high as possible from the first to the last CMJ. The jumping height was recorder for each jump with three dimensional camera. The reproducibility was assessed by Standard Error of Measurement (SEM), Minimal Difference needed to be considered real (MD), Coefficient of Variation (CV), Pearson Correlation Coefficient (PCC) with 95% confidence interval, Effect Size Cohen (ES Cohen) with 90% confidence interval, paired Student's t-test, Intraclass Correlation Coefficient (ICC 2,1) with 95% confidence interval and Magnitude-Based Inferences (MBI). Results The results summary is available in the Table 1. In this table, only few parameters are presented and only for the partial sums of the first 10, 20, 25, 30, 40 and 50 jumps. Our analyses were based on the partial sums per interval of one jump and all statistical tests listed in "Methods" section have been considered. The partial sum with twenty-five CMJ have an excellent reproducibility (MBI with 0/99/1; ICC with 0.961 [0.902/0.985]; ES Cohen with -0.03 [-0.17/0.10]; PCC with 0.966 [0.911/0,987] and p-value < 0.0001). Moreover, it induce a great height decrease (-23%) and its duration (45.5 s) is similar to the recommendation for the knee fatigability isokinetic protocol [5]. MBI (+/trivial/-) Height decrease ICC (2,1) Test duration 10 0/100/0 -12,7% 0.967 18 s 20 0/99/1 -19,0% 0.964 36 s 25 0/99/1 -23,0% 0.961 46 s 30 0/98/1 -25,6% 0.955 55 s 40 0/98/1 -32,1% 0.950 73 s 50 0/98/2 -38,4% 0.943 91 s Table 1: reproducibility statistics results depending on the number of jumps considered (magnitude-based inferences (MBI) with percentage chances of better/trivial/worst retest vs test results; height jump decrease (last jump / better jump); ICC (2,1); test duration). Discussion Because of the (semi-)continuous character of a majority of fatigability jumping test [1-4], our test is the first, at our knowledge, to explore the reproducibility of a strict CMJ jumping fatigability task. Considering the statistical (relative and absolute) reproducibility results, twenty-five maximal CMJ seems to be the best compromise between reliability of the data and physiological interpretability of test's results. Indeed, its (relative and absolute) reproducibility is excellent and it induces a greater height decrease than shorter test while remaining similar in total duration than other fatigability tests which explore the anaerobic lactic system.

This paper specifically focuses on one aspect of the experience design process, sometimes even stressed as one if its shortcomings: the time it takes to properly gain insights about possible real-life experiences of proximal or distal end-users. In the process of making sense of sometimes conflicting viewpoints found in the literature about timing and its possible impact on design processes and outcomes, this paper compares four distinct settings and addresses the following research questions: • How “time-framing” the design process possibly filters (positively or negatively) the awareness designers have about end-users; • How the experimental protocols, their inherent limitations and artificialities, do shape the designers’ involvement in the process of designing for an end-user’s experience. Results put techniques for «disciplined creativity», such as brainstorming or analogies, front-to-front with more reflective approaches that unfold over more time, and discuss respective but complementary added values of both.

This paper aims to explore adaptive behaviors developed by drivers to prevent drowsiness. Specifically, we postulate that driving expertise is associated with better drowsiness awareness, allowing experts to adequately adjust their driving behaviors when they feel drowsy. The present study was carried on a high-fidelity driving simulator coupled with an innovative system allowing objective sleepiness assessment based on EEG and Eye-tracking data. The Karolinska Sleepiness Scale was used to evaluate subjective drowsiness. The ratio between objective and subjective assessments gave an indicator of drowsiness awareness. Standard Deviation of Lateral Position (SDLP) was used as a measure of performance while driving speed and ocular fixations were recorded in order to highlight adaptive behaviors. 16 subjects were recruited from general population and categorized in two groups of expertise based on the Belgian Institute for Road Safety’s criteria. Our results show that expert drivers show better drowsiness awareness than novices and mobilize speed increasing and vigilance reallocation strategies to maintain satisfactory level of drowsiness.
