Ce chapitre rend compte d’un atelier organisé dans le cadre du colloque APPE (Accompagnement des Pratiques Professionnelles des Enseignants) en vue de permettre aux participants de découvrir la démarche de supervision réflexive mise en oeuvre dans le cadre du Master en Sciences de l’Éducation à l’Université de Liège. Plus précisément, après avoir présenté les fondements de l’approche et la trame de l’entretien de régulation, le texte illustre les étapes-clés de l’atelier. Il se clôture ensuite par quelques réflexions mettant en tension les enjeux des pratiques d’accompagnement des futurs enseignants. Au départ d’un cercle de lectures organisé sur la base d’un extrait d’entretien de régulation mené par une future formatrice d’enseignants, les participants à l’atelier ont pu découvrir les différents types d’interventions visant à favoriser, chez les futurs enseignants, une démarche d’analyse de leurs pratiques. La présentation de quelques exemples de panneaux construits par les participants pour exploiter l’extrait d’entretien témoigne de la richesse des débats qui ont eu lieu durant cette étape. En suivant la trame de l’atelier, le texte se poursuit en évoquant l’étape de décontextualisation consistant à formaliser la démarche d’intervention, tout en la mettant en relation avec les éléments préalablement identifiés par les participants.

The starting point for this paper are the archives produced by the so-called Council of Troubles, the special court established by Philip II in response to the uprising and misbehaviour of parts of the population of the Low Countries in the years 1566–1567. This institution remained active from 1567 to 1576 and was commanded by the Duke of Alva. In particular, being well aware of the potential of those cultural objects and carriers of ideas, it watched very closely the production, the distribution as well as the possession of books. The documents contain inventories of thousands of books – either forbidden or not – found in bookshops located in the southern provinces. I will focus my paper on the 12 bookshops located in Brussels visited in 1568 by religious authorities, and especially in that of Michiel van Hamont, printer from 1557 to 1585. The repressive measures taken by the Duke of Alva will be the entry point of a study on the state of book culture in Brussels during the last third of the sixteenth century. [less ▲]

This paper is concerned with modeling the behavior of random sums over time. Such models are particularly useful to describe the dynamics of operational losses, and to correctly estimate tail-related risk indicators. However, time-varying dependence structures make it a difficult task. To tackle these issues, we formulate a new Markov-switching generalized additive compound process combining Poisson and generalized Pareto distributions. This flexible model takes into account two important features: on the one hand, we allow all parameters of the compound loss distribution to depend on economic covariates in a flexible way. On the other hand, we allow this dependence to vary over time, via a hidden state process. A simulation study indicates that, even in the case of a short time series, this model is easily and well estimated with a standard maximum likelihood procedure. Relying on this approach, we analyze a novel dataset of 819 losses resulting from frauds at the Italian bank UniCredit. We show that our model improves the estimation of the total loss distribution over time, compared to standard alternatives. In particular, this model provides estimations of the 99.9% quantile that are never exceeded by the historical total losses, a feature particularly desirable for banking regulators. [less ▲]

During the last years, chemistry was involved in the worldwide effort toward environmental problems leading to the birth of green chemistry. In this context, green analytical tools were developed as modern Supercritical Fluid Chromatography in the field of separative techniques. This chromatographic technique knew resurgence a few years ago, thanks to its high efficiency, fastness and robustness of new generation equipment. These advantages and its easy hyphenation to MS fulfill the requirements of bioanalysis regarding separation capacity and high throughput. In the present paper, the technical aspects focused on bioanalysis specifications will be detailed followed by a critical review of bioanalytical supercritical fluid chromatography methods published in the literature.

Introduction: The Anterior Knee Pain Scale (AKPS) is a questionnaire used to examine the subjective symptoms, such as the functional limitations and the anterior knee pain. First developed in English, this questionnaire has since been translated and validated into several languages. The aims of the study were to translate and cross-culturally adapt the AKPS into French and to evaluate the reliability and validity of this translated version of the questionnaire. Methods: The translation part was articulated in six stages, according to international guidelines: (i) two initial translations from english to french; (ii) synthesis of the two translations; (iii) backward translations into the original language; (iv) expert committee to compare the backward translations with the original questionnaire (v) pre-final version testing and (VI) expert committee appraisal. To validate the French AKPS questionnaire, we assessed its validity, reliability and floor/ceiling effects. To do this, volunteer patients from Belgium and France, with patellofemoral pain syndrome were asked to answer the french version of the AKPS questionnaire at baseline and after 7 days, as well as the generic SF-36 questionnaire. Results: The AKPS questionnaire was translated without any major difficulties. A total of 101 subjects aged 34.49 ± 11.38 years on average were included in this study. Among them, 58.4% were women. Results indicated an excellent test-retest reliability (intraclass coefficient correlation of 0.97, 95% CI 0.96 - 0.98), a high internal consistency (Cronbach’s alpha of 0.87), a consistent construct validity (high correlations with the SF-36 questionnaire were found with domains related to physical function (r = 0.80), physical role (r = 0.70), pain (r = 0.64)) and low or moderate correlations with domains related to mental health (r = 0.26), vitality (r = 0.32), social function (r = 0.41)). Moreover, no floor/ceiling has been found. Conclusion: A valid AKPS french questionnaire is now available and can be used with confidence to better assess the disease burden associated with femoropatellar syndrom. It was successfully cross-culturally adapted into French. [less ▲]

Introduction: Some clinical series have previously evaluated the effect of PRP in the treatment of proximal patellar tendinopathies. Although it is possible that a single infiltrative administration may prove to be an effective treatment for this indication, most of the existing studies evaluated the effects of successive infiltrations which is arguably likely to increase the risks of complications. Methods: Our study is a single blinded, randomized controlled clinical trial on 20 leisure sportsmen (2 groups, respectively 1 or 2 infiltrations of pure PRP) with chronic proximal patellar tendinopathies, rebel to classical management. PRP was obtained using an aphaeresis machine. The one-year follow-up evaluation consisted of VAS, IKDC and VISA-P scores, while algometer, isokinetic and ultrasounds evaluations were carried out up to 3 months. Results: The concentration of the PRP used was similar in both groups. The VAS significantly decreased with time over the 3-month follow-up period (p=0.002), with no difference observed between the two groups (p=0.2). Values obtained with the pressure algometer increased with time across both groups over the 3-month follow-up period (p<0.0001), and values were significantly higher for Group 1 (p=0.001). The IKDC score increased with time in both groups over the follow-up period (p=0.034), with values again significantly higher for Group 1 (p=0.0026). The VISA-P score increased with time in both groups over the follow-up period (p=0.0023), with no difference observed between the groups (p=0.41). No improvements in isokinetic physical performance were observed in either group. However, pain during E30 significantly decreased over the 3-month follow-up period (p=0.027) for patients in both groups. No improvement in either jumping performances or in pain was observed in either group during opto-jump evaluation. No improvements in US findings were observed. After one year, 90% patients of group 1 did not report anymore pain during daily activities, in comparison with only 20% in group 2. Conclusions: A second closely-timed infiltration of PRP to treat proximal patellar tendinopathies is not necessary to improve the efficacy of this treatment. [less ▲]

Introduction: The treatment of patellar tendinopathies could be difficult. Recent systematic review concluded that PRP could be recommend as a treatment in such indication. Recently, the viscoelastic properties of hyaluronic acid (HA) on liquid connective tissue have been proposed for the treatment of tendinopathies. Some observations also support its use in a clinical setting to improve pain and function. We aimed to compare the effect of PRP injection versus two injections of HA after three months on patients who have a proximal patellar tendinopathy. Methods: Thirty-three sportsmen with proximal patellar tendinopathies being not relieved after minimum three months of normal physiotherapy treatments where included. Eighteen of them (group 1) have received a leukocyte poor PRP injection (obtained using an aphaeresis machine (3)) and the other fifteen (group 2) two HA injections, all of them have benefited of standardized rehabilitation. Concerning the evaluation of the pathology, algo-functional tests (visual analogic scale (VAS), pressure algometer, IKDC score, VISA-P score), isokinetic (associated to VAS) along with the patellar tendon ultrasonography (US) have been realized over three times (pre-injection, after 6 weeks, after 3 months post-injections). Results: The results of VAS (p<0,01), algometric scores (p<0,01), IKDC scores (p<0,01) and VISA-P (p<0,01) show a considerable improvement in the two groups, but not for the US findings. For the group 1, isokinetic tests show significative results for the hamstrings in C60°/s with an improvement of maximum peak torque (p=0,01) for the pathological member, a diminution (p>0,05) for the healthy limb and during the analysis of the bilateral difference (p=0,0002). For the group 2, the improvement of quadriceps maximum peak torque in C240°/s is significant (p>0,01) for the pathological knee after 6 weeks post-injections only. The VAS associated with isokinetic tests decreases significantly for all contraction modes after three months of study. Conclusion: Both PRP and HA can improve the symptoms of proximal patellar tendinopathy, even if the results are slightly better in the PRP group. [less ▲]

Introduction : Acute hamstring injury is a very common muscle injury particularly in sports that require high explosive strength, sports with impulsions and sports with running phases. Among those sports, the most widespread are soccer, rugby and sprinting. The Functional Assessment Scale for acute Hamstring injuries (FASH) assesses pain, physical activity and how patients realize some exercises while suffering hamstring injury. Current available versons are in English, in German and in Greek. Objectives : The aims of thus study were to reach a reliable and valid translation and a cross-cultural adaptation of this questionnaire in French. Methods: FASH translation and adaptation were realized in respect of international guidelines. The population composed of 116 subjects filled the questionnaire twice separated by 48-60th. FASH reliability and validity were assessed thanks to SF-36 allowing us to assess the test re-test reliability (with intra-class correlation ICC), internal consistency (with Cronbach’s alpha coefficient and construct validity, with Spearman’s correlation coefficients). Results : ICC showed a strong correlation between test and re-test (ICC total=0.9985). Internal consistency was also found to be strong with Cronbach’s alpha coefficient = 0.98. Correlation between FASH and SF-36 overall score was considered as strong (Rs=0.69, p<0.0001). Correlation with SF-36 sub scales (PF, RP, BP) were also considered as strong, showing their convergent validity. Other SF-36 subclass (GH, MH, REm, SF, VT) displayed a moderate correlation with FASH questionnaire, showing their divergent validity. No floor or ceiling effect was observed. Conclusions: FASH translation and cross-cultural adaptation into French can be considered as successful. FASF-F is now a reliable and valid tool for patients suffering acute hamstring injury.

Objective: The « Exercise-Induced Leg Pain » (EILP) questionnaire has been developed (in German) to evaluate the severity of symptoms and sports ability in individuals with exercise-induced leg pain. The purpose of the present study was to translate and cross-culturally adapt this questionnaire into French and to study the reliability and validity of the French-translated version (EILP-F). Methods: Translation and cross-culturally adaptation of the original EILP (EILP-G) was performed according to established guidelines. The translation part was articulated in six stages: (i) two initial translations from German to French; (ii) synthesis of the two translations; (iii) backward translations; (iv) expert committee to compare the backward translations with the original questionnaire; (v) pre-test; and (vi) approval of the final version of the EILP-F. To validate the EILP-F questionnaire, 84 subjects were recruited (28 pathological patients with a confirmed diagnosis of chronic leg pain, 28 asymptomatic sport students, 28 athletes healthy control). Discriminative power of the questionnaire was tested as well as reliability (internal consistency, test–retest reliability after a 7-10-day interval), construct validity and floor/ceiling effects. Results: the EILP-F version of the questionnaire has been generated without any major difficulties. The ability of the questionnaire to discriminate the three groups of subjects has been showed with a total score of 61.0 ± 18.5 for the pathologic group; 93.9 ± 7.57 for the asymptomatic group and 94.1 ± 9.79 for the control group (p-value adjusted on age = 0.008). A high internal consistency (Cronbach's alpha of 0.93) and an excellent test-retest radiality (ICC of 0.98 (95% CI 0.97-0.99, p<0.001)) indicated that the EILP-F is reliable. The EILP-F also demonstrated a good construct validity against different subscales of the Short Form-36 questionnaire, a generic quality of life questionnaire, with more than 87 % of prespecified hypotheses confirmed. Finally, no floor or ceiling effects were observed. Conclusion: The EILP-F questionnaire, a French version adapted from the original EILP-G, was successfully translated and cross-culturally adapted. The EILP-F questionnaire is consistent, valid and reliable for evaluating the French-speaking patients with chronic exercise-induced leg pain. [less ▲]

Introduction Patellar tendinopathy (PT) is commonly observed in jumping sports. Even if its biomechanic is somewhat explored, no information is known about the muscle strength profile of these patients. We aimed to determine if there exists a specific profile of patients suffering from a PT Methods 43 patients (42 males; 29 y.o +/- 9.8 y.o) suffering from PT were recruited. To be eligible, the patients must not have suffered from any other traumatic or micro-traumatic injury than the PT on the pathologic limb. After a physical examination, the tendon damage was assessed by ultrasounds examination. The patients were then tested on an isokinetic dynamometer and the peak torque per unit of mass (PTm) developed by the quadriceps and the hamstrings were recorded for various testing modalities. After each test, a visual analog scale (VAS) was used to estimate the pain felt by the patients. Results No significant correlation was found between the MTm and the demographic variables. The difference in MTm between the healthy and the pathological limbs was significant only in concentric 60°/s, for both the quadriceps and the hamstrings. Lastly, the VAS score showed that the most intense pain was experienced after the eccentric test. Conclusions There is no specific patient strength profile emerging from the isokinetic test. This stresses the importance for the clinicians to make testing and to apply a personalized treatment to each patient. On the other hand, the isokinetic eccentric testing of the quadriceps could be used to induce a mechanical stress on the tendon for a reliable pain assessment. [less ▲]

This article analyzes the ways in which a Nigerian video film about human trafficking is received by Nigerian women who experienced trafficking in their migration itinerary to Italy. This radically contextualized case study is used as a methodological “lockpick” to open up new lines of enquiry into the relationship that southern Nigerian video films create with their audiences. The essay argues that, by virtue of their specific “addressivity” (Barber 2007), the genre of Nigerian video films that focus on female migration and prostitution participates in the creation of moral publics that are concerned with the definition of the postcolonial subject’s responsibility in shaping his/her own destiny.

Wholly synthetic molecules involving both mechanical bonds and a folded secondary structure are one of the most promising architec- tures for the design of functional molecular machines with un- precedented properties. Here, we report dynamic single-molecule force spectroscopy experiments that explore the energetic details of donor–acceptor oligorotaxane foldamers, a class of molecular switches. The mechanical breaking of the donor–acceptor interactions responsible for the folded structure shows a high constant rupture force over a broad range of loading rates, covering three orders of magnitude. In comparison with dynamic force spectroscopy performed during the past 20 y on various (bio)molecules, the near-equilibrium regime of oligorotaxanes persists at much higher loading rates, at which bio- molecules have reached their kinetic regime, illustrating the very fast dynamics and remarkable rebinding capabilities of the intramolecular donor–acceptor interactions. We focused on one single interaction at a time and probed the stochastic rupture and rebinding paths. Using the Crooks fluctuation theorem, we measured the mechanical work produced during the breaking and rebinding to determine a free- energy difference, ΔG, of 6 kcal·mol−1 between the two local confor- mations around a single bond.
