Ambiguïtés de l’écriture d’invention au lycée : un champ non stabilisé
Authors: Maubant Yves 
Published: July 2018

Situé dans un schéma didactique « restreint » : celui d’un professeur qui prépare les épreuves écrites de l’EAF dans une classe de 1re (STI), cette étude articule témoignage, réflexions et repères problématiques pour développer l’hypothèse d’un champ non stabilisé, et sans doute non stabilisable. Ces questions posées à l’écriture d’invention se situent notamment dans le cadre de dynamiques de projet qui viennent conclure les séquences didactiques élaborées à partir des objets d’étude par des propositions motivantes de sujets d’invention. Elles sont reliées à des questions posées aux chercheurs ou à des réponses données dans ce numéro de Pratiques.
Les «repères problématiques » d’un praticien ont donc été reliés d’abord à l’hétérogénéité du cahier des charges didactique pour l’écriture d’invention au lycée, décliné en huit rubriques qui vont du groupement de textes fondateur à la question du style. Même si de nouvelles pratiques pédagogiques, liées entre autres à l’utilisation des Technologies de l’Information et de la Communication viennent enrichir le champ problématique de l’écriture d‘ invention au lycée, il reste nourri d’ambiguïtés quant à l’évaluation et au fait que l’activité de réécriture et le transfert générique doivent créer un discours vraisemblable.
Enfin, les difficultés viennent du choix commun d’une écriture argumentative et des genres prescrits par cette argumentation, genres de discours qui ne sont pas forcément des genres littéraires, ou surtout suffisamment classiques, c’est-à-dire faisant l’objet d’un apprentissage dans les classes. Ce que quelques études de cas, formulées à partir de sujets extraits des annales révèlent ensuite, c’est qu’il s’agit de procéder à plusieurs réévaluations didactiques, qui tiennent compte de contraintes discursives complexes et permettent une l’évaluation critériée liée à la construction d’un référentiel de formation. Des questions posées aux chercheurs concluent ce tableau critique.

Abstract
Intermediate-mass black holes (IMBHs), with masses between 100–105
M
⊙, fill the gap between stellar mass black holes and the supermassive black holes that reside in galaxy centers. While IMBHs are crucial to our understanding of black hole seed formation, black holes of less than ≈104
M
⊙ have so far eluded detection by traditional searches. Observations of the infrared coronal lines (CLs) offer us one of the most promising tools to discover IMBHs in galaxies. We have modeled the infrared emission line spectrum that is produced by gas photoionized by an active galactic nucleus (AGN) radiation field and explored, for the first time, the dependence of the infrared CL spectrum on black hole mass over the range of 102–108
M
⊙. We show that as the black hole mass decreases, the hardening of the spectral energy distribution of the accretion disk causes infrared coronal lines with the highest ionization potentials to become prominent, revealing a powerful probe of black hole mass in AGNs. We identify key emission line ratios that are most sensitive to black hole mass in the 1–30 μm range. With the unprecedented sensitivity of the James Webb Space Telescope, a large number of CLs will be detectable for the first time, providing important insight into the existence and properties of IMBHs in the local universe, and potentially revolutionizing our understanding of this class of object.

Abstract
We present the Hubble Deep UV Legacy Survey (HDUV), a 132-orbit imaging program with the WFC3/UVIS camera on board the Hubble Space Telescope (HST). The HDUV extends and builds on the few previous UV imaging surveys in the two GOODS/CANDELS-Deep fields to provide deep images over a total area of ∼100 arcmin2 in the two filters F275W and F336W. Our release also includes all the F275W imaging data taken by the CANDELS survey, which were aligned using a novel approach and combined with the HDUV survey data. By reaching depths of 27.5–28.0 mag (5σ in 0.″4 apertures), these are the deepest high-resolution UV data over such a large area taken to date. Such unique UV imaging enables a wide range of science by the community. A few of the main goals of the HDUV survey are as follows: (1) to provide a complete sample of faint star-forming galaxies at z ∼ 1–3; (2) to constrain the ionizing photon escape fraction from galaxies at z ∼ 2–3; and (3) to track the build-up of bulges and the disappearance of clumpy disk galaxies through reliable internal stellar population properties at sub-kiloparsec resolution out to z ∼ 3. The addition of the HDUV data further enhances the legacy value of the two GOODS/CANDELS-Deep fields, which now include deep 11-band HST imaging, as well as very deep ancillary data from X-ray to radio, enabling unique multi-wavelength studies. Here, we provide an overview of the survey design, describe the data reduction, and highlight a few basic analyses of the images that are available to the community as high-level science products, via the Mikulski Archive for Space Telescopes.

Klebsiella pneumoniae carbapenemase producing bacteria are defined as a group of Gramnegative bacilli that are highly resistant to drugs. The resistance of pathogens of the Enterobacteriaceae family to β-lactam antibiotics such as carbapenems is considered a major threat in the medical field. The main aim of the current study was to explore and confirm the occurrence of carbapenemase producing K. pneumoniae in the Intensive Care Unit (ICU) in different hospital environment sample sites of two Egyptian hospitals in Cairo. Isolates were collected and the screening criteria of carbapenemase producing bacteria was followed by the investigators in order to record the antimicrobial resistance patterns of all isolates in addition to the molecular identification using the 16S rDNA. This study determined the sites responsible for the spreading of carbapenem-resistant K. pneumoniae including suction tubes, ventilator tubes, instrument tables and beds. All K. pneumoniae isolates collected from the ICU of both hospitals were resistant to oxacillin, meropenem and ceftazidime. Moreover, 16S rDNA gene sequence was used to study bacterial phylogeny and taxonomy for all K. pneumoniae isolates; the accession number of all isolates is reported. We concluded that infection control department policies in each hospital should be reinforced to avoid the escalation of K. pneumoniae as nosocomial infections in hospitals. This study should be repeated in other hospitals (especially the public hospitals) to assess the level of the problem.

Authors: Vincent-Onabajo Grace , Mohammed Zulaiha 
Published: July 2018

Background: Incorporating patients’ preferences in the care they receive is an important component of evidence-based practice and patient-centred care.Objective: This study assessed stroke patients’ preferences regarding rehabilitation settings.Methods: A cross-sectional design was used to examine preferences of stroke patients receiving physiotherapy at three hospitals in Northern Nigeria. Personal factors and preferred rehabilitation setting data were obtained using the Modified Rankin Scale (to assess global disability) and a researcher-developed questionnaire. Associations between preferences and personal factors were explored using bivariate statistics.Results: Sixty stroke patients whose mean age was 53.6 ± 14.8 years participated in the study. Most of the participants (38.3%) preferred an outpatient setting, 19 (31.7%) preferred rehabilitation in their homes, 14 chose inpatient rehabilitation (23.3%), while 4 (6.7%) preferred the community. Age and source of finance were significantly associated with preferences. The majority (66.7%) of those aged ≥ 65 years expressed a preference for rehabilitation in the home or community (X2 = 6.80; p = 0.03). Similarly, most of the participants (53.3%) who depended on family finances preferred home- or community-based rehabilitation, while most of those who depended on employment income for finances preferred an outpatient rehabilitation setting (X2 = 16.80; p = 0.01).Conclusion: A preference for rehabilitation in outpatient facilities predominated followed by home-based rehabilitation, and preferences varied based on age and source of finance. These variations in preferences have implications for making rehabilitation decisions.

Abstract
Background: Neuroendocrine carcinoma (NEC) is a rare tumor arising from the diffuse neuroendocrine system. Most of these present in the advanced stage and palliative chemotherapy remains the only option. The prognosis remains poor with the standard chemotherapy regimen of platinum and etoposide (EP) providing modest survival benefit. Methods: The study was done for 3 years at a tertiary cancer center in South India. Patients with a diagnosis of metastatic NEC were analyzed for clinical and pathological characteristics. The treatment outcomes and prognostic factors were evaluated using appropriate statistical test. Results: A total of 114 patients of metastatic NEC satisfied the inclusion criteria and were analyzed. Gastrointestinal including hepatobiliary tract (33%) was the most common site of primary disease followed by lung (26%), genitourinary (15%), head and neck (14%), and unknown primary (9%). On analysis of pattern of metastasis, liver (65%) was the most common site followed by bone (54%) and lung (42%). The median overall survival was 11 months with a statistically significant difference between pulmonary and extrapulmonary disease (8 vs. 13 months; P = 0.003). Ki67% value was strongly associated with prognosis (hazard ratio 0.517, 95% confidence interval; 0.318–0.840, P = 0.008) whereas age, sex, and lactate dehydrogenase level did not show any relation with survival. Conclusion: The outcome of advanced NEC with standard chemotherapy remains poor. Larger studies with other therapeutic and novel agents are warranted to improve the treatment outcomes.

Abstract
Purpose: The purpose of this study is to report CyberKnife experience in hepatocellular carcinoma (HCC) and liver metastasis (LM). Materials and Methods: Fifty liver lesions in 31 consecutive patients with liver lesion [mean age 54.5 years (range 32-81 years), 77% were male patient, GTV <10cc in 5 patients, 11-90cc in 18 & >90cc in 8 patients respectively. Eighty percentage (25/31) had prior treatment (chemotherapy 18 patient & TACE in 7 patients). Dosage schedule was 21-45Gy/3# (mean PTV dose 33Gy, Prescription isodose 84%, target coverage 94%). Mean CI, nCI & HI were 1.19, 1.31 & 1.18 respectively. Mean liver dose was 5.4 Gy, 800 cc liver dose 11.1 Gy; Results: At mean follow-up of 12.5 months (range 1.9–44.6 months), 19 patients were expired and 12 were alive (nine patient with stable disease, two local progression, and one with metastasis). Median overall survival (OS) of all patients are 9 months (1.9–44.6 months), in HCC patients 10.5 months (2.1–44.6 months) and MT 6.5 months (1.9–24.6 months) respectively. Gr-I-II GI toxicities were in 11/50 (22%) patients. OS was influenced by PS (Karnofsky Performance Status 70–80 vs. 90–100: 9.9 vs. 16.4; P = 0.024), Child-Pugh (CP A/B vs. C: 23.6 vs. 6.5; P = 0.069), cirrhosis (only fatty liver vs. diffuse cirrhosis: 17.8 vs. 10.6; P = 0.003), prior treatment (no Rx vs. prior Rx: 30.1 vs. 8.2; P = 0.08), number of lesions (single vs. multiple: 16.4 vs. 6.9; P = 0.001), and target volume (<10 cc vs. >90 cc: 24.6 vs. 11.2; P = 0.03). Conclusion: Stereotactic body radiation therapy is a safe and effective treatment. Patient related factors such as performance status, Child-Pugh classification, cirrhosis status, prior treatment, number of liver lesion & target volume (GTV) influence the survival functions.

AbstractThe resounding success of imatinib (IM) as front line treatment in patients with chronic myeloid leukemia (CML) has certainly made a paradigm shift in the therapeutic algorithm of this disorder. The precise targeting of the BCR-ABL oncogene in CML has entitled it to be the poster child of translational medicine with a well-deserved Oscar ovation from the oncology community. Clinicians are now empowered with first-, second- and third-generation tyrosine kinases, as well as advanced molecular tools to monitor disease and characterize resistance. We have come a long way in successfully managing these patients, but there are still a significant few unmet clinical needs which need addressing and targeting to optimize clinical outcomes. This review focuses on 4 such pertinent and relevant clinical issues, which still need ironing out to fulfill our ambition of achieving ′perfection′ in this patient cohort.
Mujeres cineastas y mujeres representadas en el cine comercial español (2001-2016)
Authors: Bernárdez-Rodal Asunción , Padilla-Castillo Graciela 
Published: July 2018

Se investigan las mujeres en el cine comercial español: directoras y personajes. Metodología. Se estudian fuentes primarias y secundarias; se analizan, de forma cuantitativa y diacrónica, las películas españolas más taquilleras, entre 2001 y 2016; se examinan, de manera cualitativa y descriptiva, protagonistas, tramas y estereotipos, de un corpus de 26 películas. Resultados. El género dominante es la comedia. Hay 36 protagonistas masculinos y 23 femeninos. El grupo gira en torno a los deseos de varones. Discusión. Ellos mueven la acción y son antihéroes, con sentimentalidad infrarrepresentada. Las mujeres son acompañantes, con acciones de cuidados y mediación familiar. Conclusiones. En España, ninguna mujer ha dirigido película que haya recaudado más de 10 millones de euros. La realidad no cambiará mientras no cambie la representación. El cine comercial puede construir ciudadanos cívicos, respetuosos, humanos; y no meros consumidores, que respondan a intereses mercantiles de la industria cinematográfica.

Published: July 2018

PurposeThis study investigated the association between physical activity (PA), motor competence (MC), and perceived physical competence (PPC) in 56 boys and 65 girls aged 6–9 years.MethodsPA was recorded by Omron HJ-720IT pedometers, MC was assessed with the Bruininks-Oseretsky Test of Motor Proficiency, second edition, and PPC was determined with the physical competence subscale of the Pictorial Scale of Perceived Competence and Social Acceptance for Young Children, Greek version.ResultsANCOVA (with age as a covariate) revealed that boys were significantly more active than girls. Correlations among PA, MC, and PPC were not significant in either gender.ConclusionsIt seems that between 6 and 9 years of age, the relation among PA, MC, and PPC has not been formed yet. This age range is offered for interventions targeting these factors in order for their relationship to be enhanced later in life. However, further research for the investigation of other variables that may associate with PA at this age is needed.
Does anthropometry influence technical factors in competitive mixed martial arts?
Authors: Kirk Christopher 
Published: July 2018

PurposePrevious research has found grappling and strikes to the head to be the determining factors for success in MMA, whilst anthropometry in the form of stature and wingspan has been found to have a negligible effect. The current study was designed to determine if a relationship between technique use and anthropometry exists in MMA.MethodsThe in-competition technique data of 461 elite, professional MMA bouts were compared using Bayes factor t-tests (BF10) to determine which techniques display the highest likelihood of distinguishing between winners and losers. The differences in technique numbers between winners and losers was also compared to the anthropometric differences between winners and losers using either Bayesian Pearson’s r or Bayesian Kendall’s Tau. Simple linear regression (<i>p</i> < 0.05) was used to calculate predictive ability of anthropometrics on chosen fighting techniques.ResultsHeavyweight competitors were distinguished by striking only (BF<sub>10</sub> = 399 – 10). Light heavyweight, middleweight, featherweight, bantamweight, women’s bantamweight and women’s straw weight competitors were distinguished predominately by striking (BF<sub>10</sub> = 791661 - 7) and moderately by grappling (BF<sub>10</sub> = 75 - 7). Welterweight, lightweight and flyweight competitors were distinguished by striking techniques (BF<sub>10</sub> = 3.533e+6 – 221) to achieve dominant grappling positions (BF<sub>10</sub> = 17100 – 50). In turn, it was found that stature and/or wingspan are correlated to and can predict key technique variables at heavyweight, welterweight, lightweight and featherweight.ConclusionsThe results provide evidence of which techniques are influenced by the anthropometric differences between competitors, allowing coaches and competitors to make more informed tactical decisions in competition preparation.
The Google Earth Engine Digitisation Tool (GEEDiT) and the Margin change Quantification Tool (MaQiT) – simple tools for the rapid mapping and quantification of changing Earth surface margins
Authors: Lea James M. 
Published: July 2018

Abstract. Changes in margins derived from satellite imagery are quantitative indicators of the environmental processes and drivers acting on the Earth's surface, for example retreating ice margins or coastal changes with rising sea level. However, the large-scale rapid visualisation and analysis of the satellite record is often impractical due to factors such as computer processing power, software availability, internet connection speed and/or user expertise in remote sensing. Here are presented three new, freely accessible tools that together can be used to process, visualise and review data from the full Landsat 4–8 and Sentinel 1–2 satellite records in seconds, enabling efficient mapping (through manual digitisation) and automated quantification of margin changes. These tools are highly accessible for users from a range of remote-sensing expertise (from academics to high school students), with minimal computational, licensing and knowledge-based barriers to access. The Google Earth Engine Digitisation Tool (GEEDiT) allows users to define a point anywhere on the planet and filter data from each satellite for user-defined time frames, maximum acceptable cloud cover extent, and options of predefined or custom image band combinations via a simple graphical user interface (GUI). GEEDiT allows georeferenced vectors to be easily and rapidly mapped from each image, with image metadata and user notes automatically appended to each vector, which can then be exported for subsequent analysis. The GEEDiT Reviewer tool allows users to quality control their own/others' data and also filter existing datasets based on the spatial/temporal requirements for their particular research question. The Margin change Quantification Tool (MaQiT) is complementary to GEEDiT and GEEDiT Reviewer, allowing the rapid quantification of these margin changes by utilising two well-established methods that have previously been used to measure glacier margin change and two new methods via a similarly simple GUI. A case study of the lake-terminating glacier Breiðamerkurjökull, Iceland, is used to demonstrate the complementary functionality of GEEDiT, GEEDiT Reviewer and MaQiT, though it should be noted that MaQiT is also suitable for the (re-)analysis of existing datasets not generated by GEEDiT. MaQiT has been developed with the original aim of quantifying tidewater glacier terminus change, though the methods included within the tool have potential for wide applications in multiple areas of Earth surface science (e.g. coastal and vegetation extent change). It is hoped that these tools will allow a wide range of researchers and students across the geosciences to efficiently map, analyse and access volumes of data that would have previously proven prohibitive.
