The Role of Islam in the Yoruba-Hausa Harmonious Relations in Southwestern Nigeria
Authors: Gatawa Muhammad Mukhtar
Published: December 2016

In Nigeria, academic discourse on inter-group relations over the years has been narrowed down to only two interrelated terms: conflict and violence. This is due to the rising cases of inter-ethnic and inter-religious conflicts witnessed in the multi-cultural and multi-religious Nigeria. This paper intends to argue that the escalating ethnic and religious consciousness is greatly the handiwork of elites and politicians who employ both ethnicity and religion as effective tools for mass mobilization and manipulation of citizens psyche in their attempt to dominate the state power apparatus and resources. It also affirms the view that, as far as the Yoruba and Hausa communities of Agege are concerned, a high level of cordial inter-group relations had been achieved, owing to inter-communal mechanisms developed amongst the Yoruba and Hausa communities over the years of interaction. One of the effective vehicles through which the cordial inter-communal relations are achieved is Islam.IIUC Studies Vol.12 December 2015: 111-126

Authors: Majumder RR , Hore TR , Kader MA , Aditya TL
Published: December 2016

Field trials were conducted using ten rice genotypes including four national and international check varieties under drought prone rainfed environments of Rangpur, Nilphamari, Kurigram and Lalmonirhat districts of Bangladesh in Transplant Aman 2012 season to evaluate the growth duration and grain yield stability as well as adaptability. The experiment used randomized complete block design with three replications. Growth duration and Grain yield data were subjected to Additive Main effects and Multiplicative Interaction (AMMI) analysis. The mean growth duration of 10 genotypes over four environments showed that the longest growth duration was found for IR83383-B-B-129-4 (115.6 days) and the lowest growth duration was found for BRRI dhan56 (Ck) (113.4 days). IR82635-B-B-145-1 produced maximum 4.28 t/ha grain yield followed by 4.28 t/ha in IR82589-B-B-84-3 and the lowest grain yield was recorded for IR83376-B-B-130-2 with 3.24 t/ha. It was evident from the AMMI 1 biplot analysis that IR83377-B-B-93- 3, IR83383-B-B-129-4, IR82635-B-B-145-1, IR82635-B-B-75-2 and BRRI dhan56 (Ck) generally exhibited high yield with high main (additive) effects showing positive first principal component of the interaction (IPCA1), but IR82635-B-B-145-1 being the overall best. Hence, IR82635-B-B-145-1 was identified as specially adapted to Lalmonirhat and this environment was considered as the wide range suitable environment for the genotype. Lalmonirhat could be regarded as a good selection site for rice improvement due to stable yields. IR83377-B-B-93-3, IR82635-B-B-145-1, IR83383-B-B-129-4, IRRI 123 (Ck), BRRI dhan57 (Ck) and BINA dhan7 (Ck) were hardly affected by the G × E interaction and would perform well across a wide range of environments. In AMMI 2 biplot, IR82635-B-B-145-1 and IRRI 123 (Ck) was more responsive since they were away from the origin whereas other genotypes were nearer to the origin and hence they were more stable to different environments. IR83383-B-B-129-4 was very close to the origin, so it was more stable to different environments. Similarly Rangpur Sadar and Lalmonirhat showed similar potentiality over IR83383-B-B-129-4. The study it revealed that IR83377-B-B-93-3, IR83383-B-B-129-4, IR82635-B-B-145-1, IR82635-B-B-75-2 and IR82589-B-B-84-3 has the potentiality to show drought tolerance for the regions and might be suitable for releasing as a variety after conducting proper yield evaluation trials and Distinction, Uniformity and Stability (DUS) tests.J.

Effect of Trichoderma and fungicide on seedling establishment and yield performance of dry direct seeded boro rice
Authors: Hassan MM , Hossain S , Rahman MM , Mahmud S
Published: December 2016

Poor seedling establishment and seedling mortality is the major barrier to optimum stand establishment in dry direct seeded boro rice. Experiments were carried out at the Agronomy Field Laboratory, Bangladesh Agricultural University (BAU), Mymensingh, Bangladesh during January to June 2013 to study the effect of Trichoderma and fungicide application on seedling establishment and yield performance of dry direct seeded Boro rice. The experiment comprised ten treatment combinations of Trichoderma and fungicides viz. seed treatment with Trichoderma (M1), seed treatment with Trichoderma+spraying of Thiovit (M2), seed treatment with Trichoderma + spraying of Propiconazole (M3), seed treatment with Trichoderma + spraying of Thiovit and Propiconazole (M4), spraying of Thiovit (M5), spraying of Propiconazole (M6), seed treatment with Thiovit + spraying of Propiconazole (M7), seed treatment with Propiconazole + spraying of Thiovit (M8), spraying of mixture of Thiovit and Propiconazole (M9), and control (no fungicide or Trichoderma ) (M10).The experiments used Randomized Complete Block Design (RCBD) with three replications. Experiment revealed that seed treatment with Trichoderma harzianum followed by spraying of Thiovit gave the highest yield of rice. The study concludes that Trichoderma and then application of sulphur fungicide at 20 days after sowing could be practiced for ensuring high seedling establishment and yield of rice under dry direct seeded system in boro season.J.

Effect of variety and seed rate of mungbean on weed suppression and yield under strip tillage system
Authors: Zahan T , Ali MS , Rahman MM , Begum M , Bell RW
Published: December 2016

Mungbean can successfully be grown under strip tillage system if appropriate seeding rate can determine and adjust with machine. Due to high weed pressure in strip tillage system, selection of such mungbean varieties that have some potentialities to suppress weeds need to find out and moreover, determining optimum seed rate for different varieties could help to achieve best yield. Therefore, a study was conducted at Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during March-June, 2013 to study the effect of variety and seed rate on weed suppression and yield performance of mungbean under strip tillage system. The study comprised three mungbean varieties (BARI mung-6, BINA mung-5 and BINA mung-8) and five seed rates (20, 25, 30, 35 and 40 kg ha-1). The experiment was laid out in split-plot design with three replications. The study exposed that variety and seed rate had significant effect on plant population of mungbean, weed dry matter, number of pods plant-1, pod length, number of seeds pod-1, seed yield and stover yield of mungbean. The study results clearly found that weed population significantly reduced with increasing seeding rate of mungbean. Seeding of mungbean at 40 kg ha-1 and 35 kg ha-1 could successfully suppress weed under strip tillage system. Moreover, BINA mung-8 and BINA mung-5 had the more potentiality to suppress weeds compare to BARI mung-6. However, BINA mung-5 was found the superior among the three tested varieties that produced the highest seed yield from 35 kg ha-1 seed rate. In case of BARI mung-6 and BINA mung-8, maximum seed yield was also obtained from 35 kg ha-1 seed rate. Therefore, the study concluded that seeding of any of the three mungbean varieties at 35 kg ha-1 rate may help to obtain the satisfactory yield but the study suggest cultivation of BINA mung-5 at 35 kg ha-1 seeding rate under strip tillage system that will give not only the optimum seed yield but also provide good weed suppression.J.

Prevalence and molecular detection of shiga toxin producing Escherichia coli from diarrheic cattle
Authors: Akter MM , Majumder S , Nazir KH MNH , Rahman M
Published: December 2016

Shiga toxin-producing Escherichia coli (STEC) are zoonotically important pathogen which causes hemorrhagic colitis, diarrhea, and hemolytic uremic syndrome in animals and humans. The present study was designed to isolate and identify the STEC from fecal samples of diarrheic cattle. A total of 35 diarrheic fecal samples were collected from Bangladesh Agricultural University (BAU) Veterinary Teaching Hospital. The samples were primarily examined for the detection of E. coli by cultural, morphological and biochemical characteristics, followed by confirmation of the isolates by Polymerase Chain Reaction (PCR) using gene specific primers. Later, the STEC were identified among the isolated E. coli through detection of Stx-1 and Stx-2 genes using duplex PCR. Out of 35 samples, 25 (71.43%) isolates were confirmed to be associated with E. coli, of which only 7 (28%) isolates were shiga toxin producers, and all of them were positive for Stx-1. However, no Stx-2 positive isolate could be detected. From this study, it may be concluded that cattle can act as a reservoir of STEC which may transmit to human or other animals.J. Bangladesh Agril.

Impact of land fragmentation and soil fertility on Aus rice producers technical efficiency in Barisal district of Bangladesh
Authors: Al Amin AKM Abdullah , Rahman M Saidur , Hossain MI
Published: December 2016

This article determines the impact of land fragmentation and soil fertility on Aus rice producers technical efficiency (TE) of Barisal district in Bangladesh. A total of 60 farm households from two villages were selected using stratified random sampling procedure. Detailed input and output data for the Aus were collected in May 2015. Cobb-Douglas stochastic frontier model was used to address this TE. Results indicate that the mean TE was 0.61. Among the four land fragmentation indicators two were found to be statistically significant with anticipated signs. The positive effect of the number of plots on TE implies that variation effect exceeded the management effect and the average distance from plots to homestead indicating loss of time and inconvenience in farming management as well as inefficiencies in input use. The study also used two indicators of soil fertility (i.e., share of highly fertile land and share of not highly fertile land). Between these share of highly fertile land had positive impact on TE in rice productivity. Therefore, the study includes policy implications addressing the structural causes of land fragmentation and developing effective strategies to promote soil conservation.J. Bangladesh Agril.

Authors: Alim MA , Wadehra A , Singh AK
Published: December 2016

In this study, the textural, rheological and colour properties of different starch-based sweetened cow milk yoghurt were analyzed. Stickiness increased with increased addition level of modified starch for both homogenized (-2.231 to -5.304 N) and unhomogenized (-1.505 to -4.834 N) yoghurt sample. Firmness increased linearly for unhomogenized cow milk yoghurt sample at different incorporation level (3.019 to 4.887 N) but the homogenized cow milk yoghurt samples did not shown any clear significant difference. Viscosity also increased with increased addition level of modified starch and unhomogenized yoghurt sample at different incorporation level of modified starch showed clear and significant difference from sample to sample. Firmness, stickiness and viscosity of potato starch-based cow milk yoghurt with homogenization did not show any significant difference, but unhomogenized yoghurt sample showed linear increase of viscosity and firmness that ranged from 0.213 to 0.525 Pa.s and from 2.669 to 4.014 N, respectively. Stickiness of unhomogenized sample also increased with increased potato starch incorporation level. Viscosity increased with increased corn starch incorporation for homogenized sample. The pH values were more or less similar and the colour values showed it was lightness as white for all cases. The highest incorporation level (2%) was found for corn starch followed by potato (1.5%) and modified (1.0%) starch.J. Bangladesh Agril. Univ. 14(1): 119-126, June 2016

Authors: Khan MSR , Khan MM , Akter N , Wahab MA
Published: December 2016

Production performance of two tilapia (Oreochromis niloticus) strain viz. Chitralada and GIFT (Genetically Improved Farmed Tilapia) in fish-prawn polyculture system was compared, and possible effect of tilapia inclusion in freshwater prawn (Macrobrachium rosenbergii) culture was evaluated in 120 days of grow-out phase. There were three treatments, i.e. only freshwater prawn as control (T1), prawn + Chitralada (T2), and prawn + GIFT (T3) with three replications of each. Stocking densities for prawn juvenile was 30,000 ha-1 in all the treatments and for both tilapia strains were 10,000 ha-1. Floating feed containing 28% protein for tilapia and pelleted sinking feed for prawn were provided twice daily at a rate of 10-5% bw adjusted after each month of sampling. Water transparency was significantly lower (P<0.05) in treatment T1 with significantly higher chlorophyll-? content that increased with progression of time. Along with, plankton abundance was significantly higher (P<0.05) in T1 indicating prawn-tilapia mixed culture is better than traditional single species culture of prawn in terms of water quality management. Average individual weight, final weight, survival and production of prawn did not differ significantly (P>0.05) among the treatments. In case of tilapia, average individual weight was significantly higher in Chitralada (254.22 g) than that of GIFT (201.52 g). However, survival of GIFT was significantly higher (92.50%) than that of Chitralada (65.83%). Gross and net production of tilapia did not vary significantly. It was concluded that prawn-tilapia mixed culture is advantageous over traditional mono culture regarding production augmentation, and tilapia inclusion improving water quality.J. Bangladesh Agril.

Published: December 2016

The anther culture response in Solanum commersonii (2n = 2x = 24, 1EBN) and S. chacoense (2n = 2x = 24, 2EBN), two wild potato germplasm resources was studied to obtain haploid plants. Three accessions from each of the two species and 3200 anthers from each genotype were cultured. Authors assessed different culture media; ascorbic acid, L?cysteine and silver nitrate (AgNO3) were included to prevent browning of anther cultures. Addition of AgNO3, was effective to induce embryogenesis. The clones from S. commersonii showed different embryogenic response to androgenesis. However, the three accessions from S. chacoense did not induce any embryo in the same conditions. Ploidy level of the regenerated clones was estimated by flow cytometry and confirmed by chromosome counts. This is the first report of haploid plants obtained from anther culture in S. commersonii, with important implications in sequencing efforts and potato breeding.Plant Tissue Cult. & Biotech. 26(2): 159-173, 2016 (December)
Sink ? Source System of In vitro Suspension Culture of Celastrus paniculatus under Regulation of Monochromatic Lights
Authors: Billore Vandita , Khatediya Lalit , Jain Monica
Published: December 2016

Plants are wonderful resource of bioproducts encompassing significant value to medicines and drug development. The plant cell suspension cultures bear immense potential for production of high?value secondary metabolites and are chosen as alternative sources of raw material for industrial use. In the present study, homogenous cell suspension culture of Celastrus paniculatus a medicinally important plant was established and multifold production of alkaloids and total phenols was obtained under the influence of monochromatic lights. One month old leaf derived friable callus of C. paniculatus was used to raise homogenous suspension culture and kept on rotary shakers in cabinets illuminated with different monochromatic LED lights (Blue, Yellow and Red). The monochromatic lights proved to be a strong abiotic elicitor in driving the production of secondary metabolites so much so that the metabolites were released extracellularly and the medium served as sink or spacious pool for leaked out metabolites from the cell mass. Maximum production and enhancement in alkaloids and phenols (98 and 44.7%, respectively) over control was obtained from cell mass grown under yellow light treatment, followed by blue (64 and 23.7%) and red light (50 and 26%) treatments. Further scale up of secondary metabolite production was hence performed under yellow light conditions, starting from 2.5 gm cell mass suspended in 250 ml of media extended up to 1000 ml culture media for one month. The continuous culture system exhibited remarkable potential of this plant cell system as multifold yield of total alkaloids (91.69 ?g/1750 ml) and phenols (70.59 ?g/1750 ml) was obtained during 30 days of culture under yellow light conditions. The production was remarkably enhanced by 100?folds (5.29 to 48.21 ?g; Fig. 2) for alkaloids and 70?folds (1.73 to 46.33 ?g; Fig. 3) for phenols, from zero days to 30?day?old culture phase. Hence, strategic implementation of monochromatic lights holds great promises for controlled commercial production of myriads of valuable secondary metabolites from plant cell cultures of important medicinal plants. Present work contributes to the first reports where continuous, enhanced, multifold yield of important secondary metabolites were obtained from cell suspension culture of Celasrus paniculatus an endangered medicinal plant.Plant Tissue Cult. & Biotech. 26(2): 175-185, 2016 (December)

Published: December 2016

To evaluate the response of different genotypes of safflower (Carthamus tinctorius L.) to in vitro salt stress was conducted. Callus derived from leaflet, pedicel, hypocotyls, and adaxial and abaxial surfaces of the leaf were subjected to in vitro salt stress at 0, 100 and 200 mM of NaCl. The relative growth rate (RGR), callus growth rate (CGR), relative water content (RWC), tolerance index (TOL) and necrosis percentage were assessed. Results of analysis of variance indicated significant effects of salt stress, significant differences among genotypes for all traits and significant genotype × salt stress interaction for CGR, RWC and necrosis traits. The application of NaCl decreased RGR, CGR, RWC and TOL, significantly, while a significant increase observed across all the tested explants and genotypes for necrosis percentage data. An Iranian safflower genotype (K21) superior for RGR, RWC and TOL was the most salt tolerant genotype at the cellular level.Plant Tissue Cult. & Biotech. 26(2): 231-242, 2016 (December)

Authors: Hossen Kabir , Rahman Fazlur , Mashreky Saidur Rahman
Published: December 2016

Poverty, large population, socio- economic inequalities and inadequate access to proper health care facilities are the key causes of under nutrition in Bangladesh. Adolescents are the most vulnerable group for under nutrition and having great consequence as they will be parent in future. Studies on nutritional status of adolescent girls are fewer in number and have great effect for intervention. The objective of this study was to assess the nutritional status and predisposing factors of under nutrition among the adolescent girls in Bangladesh. A community-based cross-sectional survey was carried out from July to December 2013. Adolescent girls were the study population. Data was collected by face to face interview at household level. According to BMI category (kg/m2) the prevalence of under-weight (BMI<18.5) was found 65.9% and as per Gomez Classification (Weight for age), the prevalence of malnutrition was 48.2% (mild), 23.5% (moderate) and 2.8% (severe) categories and finally, as per Water Low Classification wasting found 16.6% (mild), 3.5%(moderate) and 0.2% severe categories. On the other hand, stunting found 39.6 % (mild), 9.2% (moderate) and 2.3% (severe) categories. Prevalence of under nutrition was found much higher (82.3%) among younger age group (?12 years). Higher prevalence of under-nutrition also found among the functionally illiterate adolescent girls, it was 75.8% and 51.3% among illiterate and literate group respectively. In both of the cases difference was statistically significant (p<0.001). The prevalence of illness found higher among under-weight adolescent girls in last two weeks compare to healthy adolescent girls both in rural and urban settings. This difference also found statistically significant (p<0.001). Under nourishment found higher among younger and low literate girls. Prevalence of other symptoms is also found higher among them.South East Asia Journal of Public Health Vol.6(1) 2016: 3-7

Hypertension is one of the leading risk factors for global mortality. A community based cross sectional descriptive study was conducted in Hmawbi Cantonment Area, Yangon Region in November, 2015. This study aimed to identify the prevalence, awareness and risk factors of hypertension concerning smoking, alcohol dinking, eating food pattern, taking regular exercise, stressful condition and body mass index (BMI). The sample consisted of 210 respondents from three Units (Light Infantry Regiments) were randomly selected to participate in the study. A pre-tested structured questionnaire was used as a data collection tool. It was found that 33.3% of respondents had hypertension; 55.7% achieved good awareness on hypertension as well; 16.7% respondents were current smoker; 7.6% had the history of alcohol drinking; 67.1% respondents took regular exercise; 29.5% respondents were in stressful condition; 32.9% re-spondents were overweight and 19.5% were obese. Hypertension was significantly associated with age (p-0.001), family income (p<0.001), awareness level (p-0.01), current smoking status (p<0.001), alcohol drinking (p<0.001), regular exercise taking (p<0.001), stressful condition (p<0.001), and increase BMI (p<0.001) of respondents. This setting in Hmawbi evidenced that age, family income, smoking, alcohol drinking, consumption of salty and fast food, stressful condition and increase BMI were identified as risk factors and taking regular exercise was protective. Over-all, over 50% of respondents having good awareness show that favorable circumstances exist for further strengthening the hypertension prevention and control program. These findings have implications for future public health interven-tion and clinical efforts to decrease the prevalence of hypertension among population.South East Asia Journal of Public Health Vol.6(1) 2016: 20-26

Parcours d’inclusion de jeunes enfants en situation de handicap en maternelle : rapport(s) au cadre des règles de vie de classe
Authors: Janner-Raimondi Martine , Bedoin Diane
Published: December 2016

Dix ans après l’adoption de la loi du 11 février 2005, cet article propose un éclairage sur les transformations qualitatives induites dans les écoles maternelles par l’inclusion des jeunes enfants en situation de handicap. À partir d’un double cadre théorique, phénoménologique et interactionniste, il s’agit d’analyser les leviers et les freins à l’inclusion scolaire et sociale des jeunes enfants en situation de handicap en classe ordinaire. Le corpus recueilli est constitué d’entretiens semi-directifs menés auprès de professionnels de la petite enfance non spécialisés (directrices d’école, enseignants et auxiliaires de vie scolaire) et d’observations de classe filmées dans deux classes de maternelle. L’analyse croisée des données permet de saisir le sens attribué à un parcours d’inclusion et de voir les transformations des pratiques professionnelles qui en découlent. Les résultats exploratoires formulés permettent de repérer en quoi un cadre partagé par tous les acteurs et modulable en fonction des besoins éducatifs particuliers est susceptible de favoriser le processus d’inclusion.
« Outiller » les enseignants spécialisés, un enjeu de formation pour des pratiques inclusives renouvelées ?
Authors: Leroyer Laurence
Published: December 2016

Afin de mieux comprendre les pratiques des enseignants spécialisés, nous avons mené une recherche sur les pratiques évaluatives des enseignants exerçant en ULIS (Unité localisée pour l’inclusion scolaire). Cette recherche, dont le cadre théorique se réfère à la double approche de Robert et Rogalski (2002) se fonde sur huit entretiens compréhensifs (Kaufmann, 2014). Les résultats montrent un déficit de connaissances et de ressources et, pour certains, une conception de l’évaluation dissociée des aspects didactiques. Se pose alors la question de la formation, d’autant plus importante quand celle-ci semble parfois secondaire aux yeux des personnes interrogées. Il apparaît aussi que les pratiques collaboratives font défaut, mais qu’une certaine diffusion des savoirs se met en place : lorsque les enseignants spécialisés sont « ressources », des enseignants non spécialisés s’approprient des gestes adaptés en direction des élèves inclus permettant l’accessibilité pédagogique. En lien avec les recherches centrées sur la thématique des ressources pour enseigner, « outiller » les enseignants spécialisés émerge alors comme un nouvel enjeu de formation, au service de l’école inclusive.
Soutenir l’usage des aides technologiques par les élèves dyslexiques dans un contexte inclusif
Authors: Bacquelé Vanessa
Published: December 2016

L’utilisation des outils numériques au sein de l’École est devenue une possibilité de promouvoir l’accessibilité des apprentissages pour les élèves en situation de handicap. La situation des élèves dyslexiques à qui on attribue des aides technologiques pour accéder au langage écrit, interroge profondément les enseignants sur l’éventail de leurs compétences et l’indispensable évolution de leurs pratiques. Les données recueillies auprès d’élèves, de parents et d’enseignants à travers des questionnaires et lors d’entretiens, permettent de rendre compte de l’usage de ces outils par les élèves dans le cadre de la classe et de présenter ce qui freine la mise en œuvre de leurs projets de compensation. À partir de ces expériences de terrain se dessinent alors les contours d’une formation des enseignants qui développerait les démarches susceptibles de promouvoir au sein de la classe le respect des singularités de chacun au service d’une cohésion et d’une appartenance au groupe. Elle conduirait aussi les enseignants à modifier certaines habitudes pédagogiques non plus pour les adapter mais pour les transformer voire développer un autre cadre de références assorti d’une nouvelle expertise.
Pratiques inclusives en milieu ordinaire : accessibilité didactique et régulations
Authors: Suau Géraldine , Assude Teresa
Published: December 2016

Dans le sillage de la théorie anthropologique du didactique (Chevallard, 1999) et de la théorie de l’action conjointe (Sensevy & Mercier, 2007 ; Sensevy, 2011), notre article a comme but de poursuivre l’étude de l’accessibilité didactique définie comme l’ensemble des conditions qui permettent aux élèves d’avoir accès aux savoirs. Cette étude est faite à partir du point de vue de la dynamique topogénétique, soit de la manière dont le partage des responsabilités des tâches et les positions de l’enseignant et des élèves influencent l’accès aux savoirs. Pour cela, nous prenons appui sur une séance ordinaire d’enseignement en mathématiques et sur les récits tenus par les acteurs, et nous observons les phénomènes liés à la forme d’étude du travail en petit groupe et aux régulations apportées par l’enseignant et/ou par des élèves. Nos questions sont : quelles sont les situations « favorables » pour rendre possible l’accès au savoir ? Quels sont la place et le rôle des acteurs (enseignant-élèves) pour créer des conditions d’accessibilité didactique ? Les réponses à ces questions mettent en évidence différents types de régulations topogénétiques, et leurs effets sur l’engagement ou non de l’élève en situation de handicap dans le travail mathématique.
Difficultés de l’éducation inclusive en République tchèque : les besoins éducatifs particuliers, entre défauts et troubles
Authors: Kohout-Diaz Magdalena
Published: December 2016

En République tchèque comme en France, l’approche inclusive est étayée par la définition de besoins éducatifs particuliers. Cette nomenclature peine cependant à s’imposer tant elle est articulée aux troubles de la santé et spécialement de la santé mentale. De quelles évolutions sociohistoriques les orientations actuelles sont-elles tributaires ? Sur quelles logiques et classifications s’appuient-elles ? Quel est l’impact inclusif des approches réelles ? À partir de données ethnographiques, l’étude montre trois difficultés : le paradoxe de la reconnaissance des particularités, le flou des nomenclatures et leur étayage sur les troubles mentaux. Elle met en valeur l’accentuation de perspectives sanitaires, particulièrement en ce qui concerne le comportement ou les origines socioculturelles. La question de leur efficience en matière d’inclusion reste posée. Le souci louable mais parfois rhétorique de non-discrimination peut aboutir in fine à rabattre les conduites déviantes sur l’anormalité pathologique du trouble mental.
Dix années de politique inclusive à l’école : quel bilan ?
Authors: Chevallier-Rodrigues Émilie , Courtinat-Camps Amélie , de Léonardis Myriam
Published: December 2016

Cette note a pour objectif de synthétiser les fondements du paradigme inclusif et de souligner les controverses qui le traversent. Depuis la loi du 11 février 2005, la prise en charge des élèves en situation de handicap vise l’accessibilité à la scolarisation et à la vie sociale, la participation civique de tous et le droit à la compensation. Face au passage d’un modèle intégratif à un modèle inclusif, les professionnels, même s’ils en soulignent la faisabilité, se retrouvent quelquefois en difficulté dans leur pratique. Ce paradigme inclusif ne peut opérer sans la mise à disposition de moyens conséquents pour la formation des professionnels et de pratiques coopératives entre les différents acteurs concernés. Les résultats des différentes études, concernant les effets de l’inclusion sur le développement cognitif et socioaffectif des élèves, ne font pas consensus. Les pistes de travail possibles pour la poursuite de l’inclusion se centrent sur diverses pratiques innovantes tant pour la formation des professionnels que pour les adaptations pédagogiques et ce, dans le but de s’inscrire dans une pratique inclusive « raisonnée ».

Ubiquitination was recently identified as a central process in the pathogenesis and development of numerous inflammatory diseases, such as obesity, atherosclerosis, and asthma. Treatment with proteasomal inhibitors led to severe side effects because ubiquitination is heavily involved in a plethora of cellular functions. Thus, new players regulating ubiquitination processes must be identified to improve therapies for inflammatory diseases. In addition to their role in adaptive immunity, endosomal MHC class II (MHCII) molecules were shown to modulate innate immune responses by fine tuning the TLR4 signaling pathway. However, the role of MHCII ubiquitination by membrane associated ring-CH-type finger 1 (MARCH1) E3 ubiquitin ligase in this process remains to be assessed. In this article, we demonstrate that MARCH1 is a key inhibitor of innate inflammation in response to bacterial endotoxins. The higher mortality of March1−/− mice challenged with a lethal dose of LPS was associated with significantly stronger systemic production of proinflammatory cytokines and splenic NK cell activation; however, we did not find evidence that MARCH1 modulates LPS or IL-10 signaling pathways. Instead, the mechanism by which MARCH1 protects against endotoxic shock rests on its capacity to promote the transition of monocytes from Ly6CHi to Ly6C+/−. Moreover, in competitive bone marrow chimeras, March1−/− monocytes and polymorphonuclear neutrophils outcompeted wild-type cells with regard to bone marrow egress and homing to peripheral organs. We conclude that MARCH1 exerts MHCII-independent effects that regulate the innate arm of immunity. Thus, MARCH1 might represent a potential new target for emerging therapies based on ubiquitination reactions in inflammatory diseases.
Spectral asymptotics for first order systems
Authors: Avetisyan Zhirayr , Fang Yan-Long , Vassiliev Dmitri
Published: December 2016

This is a review paper outlining recent progress in the spectral analysis of first order systems. We work on a closed manifold and study an elliptic self-adjoint first order system of linear partial differential equations. The aim is to examine the spectrum and derive asymptotic formulae for the two counting functions. Here the two counting functions are those for the positive and the negative eigenvalues. One has to deal with positive and negative eigenvalues separately because the spectrum is, generically, asymmetric.

Grothendieck–Lidskii trace formula for mixed-norm and variable Lebesgue spaces
Authors: Delgado Julio , Ruzhansky Michael , Wang Baoxiang
Published: December 2016

In this note we present the metric approximation property for weighted mixed-norm

L_w^{(p_1,\dots, p_n)}

and variable exponent Lebesgue type spaces. As a consequence, this also implies the same property for modulation and Wiener-Amalgam spaces. We then characterise nuclear operators on such spaces and state the corresponding Grothendieck–Lidskii trace formulae. We apply the obtained results to derive criteria for nuclearity and trace formulae for periodic operators on Rn and functions of the harmonic oscillator in terms of global symbols.

A generalised Gauss circle problem and integrated density of states
Authors: Lagacé Jean , Parnovski Leonid
Published: December 2016

Counting lattice points inside a ball of large radius in Euclidean space is a classical problem in analytic number theory, dating back to Gauss. We propose a variation on this problem: studying the asymptotics of the measure of an integer lattice of affine planes inside a ball. The first term is the volume of the ball; we study the size of the remainder term. While the classical problem is equivalent to counting eigenvalues of the Laplace operator on the torus, our variation corresponds to the integrated density of states of the Laplace operator on the product of a torus with Euclidean space. The asymptotics we obtain are then used to compute the density of states of the magnetic Schrödinger operator.
Heat kernel estimates for general boundary problems
Authors: Li Liangpan , Strohmaier Alexander
Published: December 2016

We show that not feeling the boundary estimates for heat kernels hold for any non-negative self-adjoint extension of the Laplace operator acting on vector-valued compactly supported functions on a domain in

\mathbb R^d

. They are therefore valid for any choice of boundary condition and we show that the implied constants can be chosen independent of the self-adjoint extension. The method of proof is very general and is based on finite propagation speed estimates and explicit Fourier Tauberian theorems obtained by Y. Safarov.
Spectral asymptotics for compact self-adjoint Hankel operators
Authors: Pushnitski Alexander , Yafaev Dmitri
Published: December 2016

We describe large classes of compact self-adjoint Hankel operators whose eigenvalues have power asymptotics and obtain explicit expressions for the coefficient in front of the leading term. The results are stated both in the discrete and continuous representations for Hankel operators. We also elucidate two key principles underpinning the proof of such asymptotic relations. We call them
the localization principle
and
the symmetry principle
. The localization principle says that disjoint components of the singular support of the symbol of a Hankel operator make independent contributions into the asymptotics of eigenvalues. The symmetry principle says that if the singular support of a symbol does not contain the points 1 and –

On a coefficient in trace formulas for Wiener–Hopf operators
Authors: Sobolev Alexander V.
Published: December 2016

Let

a = a(\xi), \xi \in \mathbb R,

be a smooth function quickly decreasing at infinity. For the Wiener–Hopf operator

W(a)

with the symbol

a

, and a smooth function

g\colon \mathbb C \to \mathbb C

, H. Widom in 1982 established the following trace formula:

\mathrm {tr}(g(W(a)) - W(g \circ a)) = \mathcal B(a; g),

where

\mathcal B(a; g)

is given explicitly in terms of the functions

a

and

g

. The paper analyses the coefficient

\mathcal B (a; g)

for a class of non-smooth functions

g

assuming that

a

is real-valued. A representative example of one such function is

g(t) = |t|^{\gamma}

with some

\gamma \in (0, 1]

Logarithmic lower bound on the number of nodal domains
Authors: Zelditch Steve
Published: December 2016

We prove that the number of nodal domains of eigenfunctions grows at least logarithmically with the eigenvalue (for almost the entire sequence of eigenvalues) on certain negatively curved surfaces. The geometric model is the same as in prior joint work with J. Jung, where the number of nodal domains was shown to tend to infinity. The surfaces are assumed to be “real Riemann surfaces,” i.e. Riemann surfaces with an anti-holomorphic involution with non-empty fixed point set. The eigenfunctions are assumed to be even or odd, which is automatically the case for generic invariant metrics. The logarithmic growth rate gives a quantitative refinement of the prior results.
Resonances for asymptotically hyperbolic manifolds: Vasy’s method revisited
Authors: Zworski Maciej
Published: December 2016

We revisit Vasy’s method ([27] and [28]) for showing meromorphy of the resolvent for (even) asymptotically hyperbolic manifolds. It provides an effective definition of resonances in that setting by identifying them with poles of inverses of a family of Fredholm differential operators. In the Euclidean case the method of complex scaling made this available since the 70’s but in the hyperbolic case an effective definition was not known till [27] and [28]. Here we present a simplified version which relies only on standard pseudodifferential techniques and estimates for hyperbolic operators. As a byproduct we obtain more natural invertibility properties of the Fredholm family.

We report a case of a 41-year-old man with a solitary functioningleft kidney and history of chronic pelvic discomfort associatedwith lower urinary tract symptoms. Imaging revealed a largecystic structure in the pelvis attached to a dilated tortuous ureteron the right with congenital absence of the right kidney. The patientunderwent laparoscopic removal of the pelvic cyst and dilatedright ureter. Pathological assessment revealed mesonephric remnantsrepresenting dysplastic renal tissue attached to a dilated andobstructed megaureter, extending into the bladder wall and forminga large pelvic cyst. The patient’s symptoms resolved. A laparoscopicapproach represents an excellent surgical option for pelvicpathology.Nous décrivons le cas d’un homme de 41 ans porteur d’un seulrein fonctionnel (gauche) et ayant des antécédents de douleurspelviennes chroniques liées à des symptômes affectant les voiesurinaires inférieures.
