Supporting children with 'Social, Emotional and Behavioural Difficulty (SEBD)' in mainstream: teachers' perspectives

description: In this small-scale, qualitative study, the experiences of nine teachers who support learners identified with social, emotional and behavioural difficulties (SEBD) in mainstream primary schools are considered. A narrative approach enabled teachers to share their complex portrayals of practices and feelings about their roles. Perspectives on models of disability and disability rights, performativity, professional identity for teachers, and SEBD, have informed analysis and understanding of the stories teachers told. The study explores how the relationship between teachers’ professional identity and well-being and the expectations imposed upon them in a neoliberal influenced education system brings about pressures and concerns. Attempts by the teachers to achieve a balance between what they feel they ought to do (to meet policy expectations) and what they feel they should do (to meet the entitlements of children) has led to excessive workloads and complex emotional responses. Reflections on the way these teachers constructed discourses about why some children exhibit disruptive and challenging behaviours provide an understanding of how their negotiation of this challenging context impacts on the relationships they form with the children. The findings suggest that teachers experience confusion due to the complexities and contradictions they are faced with when trying to support learners identified with SEBD in an education system which incorporates policies guided by different models of disability. The study concludes by suggesting that teachers’ critical reflection on the discourses they have constructed in relation to models of disability could bring about a new way of shaping their practice. It is argued that a rights-based approach to teaching children who exhibit challenging, disruptive and concerning behaviours would emancipate children from the restrictive views and beliefs teachers seem to have developed. Approaches which focus on children’s rights to inclusive learning opportunities, which reflect their entitlement to an education, would go some way to addressing the confusion, contradiction and pressures these teachers described.

description: This thesis is based on the evidence of the use of range by laying hens from twoseparate studies that were carried out on commercial flocks. The first studyinvolved a direct observation of 6 flocks of laying hens whereas the second studywas carried out on a single flock of laying hens using a still digital camera.Mapping of the outdoor range into three zones, namely; apron (0-10metres),enriched (10-50metres) and range (beyond 50metres), was carried out in bothstudies determine whether it influenced the distribution, behaviour, nearestneighbour distance (NND) and feather condition of the hens.Based on the estimates of the total number of hens recorded outdoors, it was foundthat 14.5% of the hens used the range in the first study, with 6.0% of the hens seenin the apron, 4.8% in the enriched and the remaining 3.7% in the outer range zone.This ranging pattern was further confirmed by the quadrat head counts, where thehens used the apron most but showed a significant decrease in the use of otheroutdoor zones as distance increased from the shed (p < 0.001). The results of thetwo studies showed that range use peaked in the morning and decreasedsignificantly in the afternoon (p < 0.001). Range use was found to increasesignificantly with age (p < 0.001) in the first study, although there was a significantdecrease in the number of hens outside the shed as the flocks got larger (p < 0.001).The age effect reported in the six-flock study was complemented by the significantpositive effect of the week of outdoor access on the ability of the hens to use therange (p < 0.001) in the single flock study. Range use increased as outdoortemperature rose in the six-flock study whereas increased outdoor temperatureresulted in a decline in range use in the single flock study. NND of the hens wasiimeasured in the six-flock study and was found to decrease significantly towardsthe shed (p < 0.001) and as the hens aged (p < 0.001). There was evidence that theuse of distant and less crowded outdoor locations by the hens in the first studywas associated with improved feather conditions.The evidence presented in the two studies presented in this thesis showed that thehens were unevenly distributed in the range, with reduced hen density (hen/m2)towards the outer range and that an improvement in the use of distant parts of therange may have beneficial effects on the hens.

description: Possible main formation sites of F in the Universe include AGB stars, the ν-process in Type II SNe, and/or W-R stars. The importance of the W-R stars has theoretically been questioned and they are probably not needed in the modelling of the chemical evolution of F in the solar neighborhood. It has, however, been suggested that W-R stars are indeed needed to explain the chemical evolution of F in the Bulge. The molecular spectral data of the often used HF-molecule has not been presented in a complete and consistent way and has recently been debated in the literature. In this article we determine the [F/O] vs. [O/H] trend in the Bulge to investigate the possible contribution from W-R stars. Additionally, we present here a HF line list for the K- and L-bands (including the often used 23358.33 Å line) and an accompanying partition function. The F abundances were determined using spectral fitting from hi-res NIR spectra of eight K giants recorded by the spectrograph CRIRES. We have also re-analyzed five previously published Bulge giants using our new HF molecular data. We find that the F-O abundance in the Bulge probably cannot be explained with chemical evolution models including only AGB-stars and the ν-process in SNe Type II, i.e. a significant amount of F production in W-R stars is likely needed to explain the F abundance in the Bulge. Concerning the HF line list, we find that a possible reason for the inconsistencies in the literature, with two different excitation energies being used, is two different definitions of the zero-point energy for the HF molecule and therefore also two accompanying different dissociation energies. Both line lists are correct, as long as the corresponding consistent partition function is used in the spectral synthesis. However, we suspect this has not been the case in several earlier works leading to F abundances 0.3 dex too high.

description: A simple system of coupled kinetic equations for quark and gluon anisotropic systems is solved numerically. The solutions are compared with the predictions of the anisotropic hydrodynamics describing a mixture of anisotropic fluids. We find that the solutions of the kinetic equations can be well reproduced by anisotropic hydrodynamics if the initial distribution are oblate for both quarks and gluons. On the other hand, the solutions of the kinetic equations have a different qualitative behavior from those obtained in anisotropic hydrodynamics if the initial configurations are oblate-prolate or prolate-prolate. This suggests that an extension of the anisotropic hydrodynamics scheme for the mixture of anisotropic fluids is needed, where higher moments of the kinetic equations are used and present simplifications are avoided.
Double-parton scattering contribution to production of jet pairs with large rapidity separation at the LHC

description: We discuss production of four-jet final state $pp \rightarrow j j j j X$ in proton-proton collisions at the LHC through the mechanism of double-parton scattering (DPS) in the context of jets with large rapidity separation. The DPS contributions are calculated within the so-called factorized Ansatz and each step of DPS is calculated in the LO collinear approximation. The LO pQCD calculations are shown to give a reasonably good descritption of recent CMS and ATLAS data on inclusive jet production and therefore this formalism can be used to reliably estimate the DPS effects. Relative contribution of DPS is growing at large rapidity distance between jets. This is consistent with our experience from previous studies of double-parton scattering effects in the case of open and hidden charm production. The calculated differential cross sections as a function of rapidity distance between the most remote in rapidity jets are compared with recent results of LL and NLL BFKL calculations for Mueller-Navelet (MN) jet production at $\sqrt{s} = 7$ TeV. The DPS contribution to widely rapidity separated jet production is carefully studied for the present energy $\sqrt{s}$ = 7 TeV and also at the nominal LHC energy $\sqrt{s}$ = 14 TeV and in different ranges of jet transverse momenta. The differential cross section as a function of dijet transverse momenta as well as two-dimensional ($p_{T}(y_{min})\times p_{T}(y_{max})$)-plane correlations for DPS mechanism are also presented. Some ideas how the DPS effects could be studied in the case of double dijet production are suggested.

Identification of bacteriocin produced by Klebsiella pneumoniae

Subjects: C100 - Biology

description: The title of the research project is the ‘identification of bacteriocin produced by Klebsiella pneumoniae’.In the experiment two different strains of K. pneumoniae were used; a bacteriocin producer strain K. pneumoniae 957 and a bacteriocin sensitive strain K. pneumoniae 757. The aim of this project was to isolate the bacteriocin so it could be identified by mass spectrometry.The release of proteins in the cell lysate was confirmed by carrying out SDS poly acrylamide gel electrophoresis and the presence of bacteriocin was confirmed by bio assay test plate which showed the inhibition of growth of K. pneumoniae 757 by K. pneumoniae 957 cell lysate. To isolate the bacteriocin, native PAGE was used and for identification of the protein band on the gel bio assay test was performed.The protein was isolated by ion exchange chromatography and identified by Mass/Spectrometry. BLAST search was used for finding the homologous peptide sequence. The search result directed towards new bacteriocin produced by K. pneumoniae. According to the BLAST search results the bacteriocin has similarities with cloacin and colicin, produced by Enterobacter cloacae and Escherichia coli respectively. Both bacteriocins are ribonuclease.This new finding leads to many possible areas for exploring the similarities between cloacin and the new bacteriocin. To this stage new bacteriocin uses the same cell surface receptor for attachment and has a very similar cytotoxic domain and receptor binding domain that means the killing mechanism is the same as cloacin. But it is unknown if the victim is rRNA or tRNA, e.g., colicins E4 and E6 have sequence homology with colicin E3 but the E4 and E6 target amino acid incorporation and E3 directly cleaves 16s rRNA (Tomita et al, 2000). Therefore, if new bacteriocin has sequence homology with cloacin, it can have a different mechanism of action inside the sensitive cell for degrading RNA or it can have a different process of synthesis. All these facts can be used in future works to find out more about the new bacteriocin.

description: Text Document Clustering is one of the fastest growing research areas because of availability of huge amount of information in an electronic form. There are several number of techniques launched for clustering documents in such a way that documents within a cluster have high intra-similarity and low inter-similarity to other clusters. Many document clustering algorithms provide localized search in effectively navigating, summarizing, and organizing information. A global optimal solution can be obtained by applying high-speed and high-quality optimization algorithms. The optimization technique performs a globalized search in the entire solution space. In this paper, a brief survey on optimization approaches to text document clustering is turned out.

description: A fundamental Software-as-a-Service (SaaS) characteristic in Cloud Computing is to be application-specific; depending on the application, Cloud Providers (CPs) restrict data formats and attributes allowed into their servers via a data validation process. An ill-defined data validation process may directly impact both security (e.g. application failure, legal issues) and accounting and charging (e.g. trusting metadata in file headers). Therefore, this paper investigates, evaluates (by means of tests), and discusses data validation processes of popular CPs. A proof of concept system was thus built, implementing encoders carefully crafted to circumvent data validation processes, ultimately demonstrating how large amounts of unaccounted, arbitrary data can be stored into CPs.

description: Ce travail de mémoire permet d’informer les parents et enseignants des impacts de la surconsommation d’écrans sur l’attention et les performances scolaires des élèves. Notre recherche a été effectuée sous forme de méthode expérimentale dans deux classes de 7 et 8H en novembre et décembre 2018. Les données ont été récoltées à l’aide de tests d’attention et de questionnaires distribués au même moment dans les deux classes. Ce mémoire concernant en majeur partie le milieu familial de nos élèves, nous avons décidé de prendre en compte le point de vue de leurs parents. Les analyses de ces données mettent en évidence l’effet néfaste d’une surconsommation d’écrans sur l’attention, les performances scolaires et le sommeil des enfants de 11-12 ans. Nous avons également pu remarquer certaines variables influençant la consommation d’écrans. En effet, celle-ci varie en fonction de l’origine sociale, du genre et de la fréquence des activités pratiquées en extérieurs des élèves. La discussion des résultats articule notre recherche avec les découvertes de différents chercheurs. Nous avons constaté que les élèves ayant une consommation élevée d’écrans en étaient conscients tout comme leurs parents. Pourquoi, dans ce cas, continuent-ils de surconsommer ? Nous essayons de répondre à cette question lors de la discussion de nos résultats. Notre mémoire se termine avec quelques conseils destinés aux parents permettant de diminuer la surconsommation de leur enfant. Nous espérons qu’avec une conscience accrue des conséquences néfastes des écrans sur leur enfant, les parents porteront une plus grande attention à la consommation d’écrans de leur enfant.

Apart from the conventional techniques, such as threshold and hysteresis based schemes, recently many artificial intelligent techniques such as Fuzzy Logic, Artificial Neural Network (ANN) etc. are also used for taking handoff decision. In this paper, an Artificial Neural Network based handoff algorithm is proposed and its performance is studied. We have used ANN here for taking fast and accurate handoff decision. In our proposed handoff algorithm, Backpropagation Neural Network model is used.The advantages of Back propagation method are its simplicity and reasonable speed. The algorithm is designed, tested and found to give optimum results.

description: In this paper we borrow concepts from Information Theory and Statistical Mechanics to perform a pattern recognition procedure on a set of x-ray hazelnut images. We identify two relevant statistical scales, whose ratio affects the performance of a machine learning algorithm based on statistical observables, and discuss the dependence of such scales on the image resolution. Finally, by averaging the performance of a Support Vector Machines algorithm over a set of training samples, we numerically verify the predicted onset of an optimal scale of resolution, at which the pattern recognition is favoured.
Primary caregiving fathers and breadwinning mothers: social psychological mechanisms underlying the division of family roles

description: Over recent decades there has been significant progress towards gender equality in the workplace and at home. Transformations in work and childcare domains have occurred for families in Western societies, including de-gendered parenting, in which childcare responsibilities are shared equally or assumed primarily by the father. Although these arrangements constitute a recent and rare phenomenon, this increase in proportion has been matched by an academic interest.Using quantitative data from traditional and role-reversed couples, this research aims to explore the social psychological mechanisms underlying non-normative behavioural choices, as well as the consequences for couples' relationship quality, well-being and life satisfaction. Traditional couples are those in which the mother bears primary responsibility for child care while the father is the main breadwinner. In non-traditional role-reversed couples the opposite occurs. A sample of 242 individual parents with children from birth to 12 years old, completed an extensive questionnaire. Involvement in work and childcare, social psychological variables, relationship and life satisfaction, perceptions of their division of responsibilities and socio-demographic characteristics were examined. Results show how social prescriptions and structural characteristics are limiting the intersection between the mother and the father role, and help us understand how both roles can be more similar than different. The findings also disclose how by being involved men are assisting women’s career and help make a distinction between traditional and role reversed women’s views of the appropriate parental role for men and women. Furthermore, the results contribute for a better understanding of how gender ideologies and non-essentialist perceptions differ between couples in different arrangements and how they relate to involvement in childcare and well-being, as well as the role of choice in well-being, life and marital satisfaction.

description: Incorrect choice of measuring geometry and signal discrimination thresholds for the BaF2 PAL spectrometer can lead to a significant distortion in the measured spectrum of positron lifetime. The contribution of the distorted events for non-optimal geometry (e.g. "face to face") can exceed 50%. It reduces the lifetime of the spectral components and redistributes intensities. Geant4 simulation permits to evaluate influence of measuring geometry on spectrum distortion and to choose the most appropriate discrimination thresholds. Optimal geometry with a lead absorber between the detectors permits to reduce contribution of distorted coincidences to less than 1% and to provide sufficiently high count rate of true events.
The influence of primordial magnetic fields on the spherical collapse model in cosmology

description: Despite the ever growing observational evidence for the existence of the large scale magnetic fields, their origin and the evolution are not fully understood. If the magnetic fields are of primordial origin, they result in the generation of the secondary matter density perturbations and the previous studies show that such density perturbations enhance the number of dark matter halos. We extend the conventional spherical collapse model by including the Lorentz force which has not been implemented in the previous analysis to study the evolution of density perturbations produced by primordial magnetic fields. The critical over-density $δ_{\rm c}$ characterizing the halo mass function turns out to be a bigger value, $δ_{\rm c}\simeq 1.78$, than the conventional one $δ_{\rm c}\simeq 1.69$ for the perturbations evolved only by the gravitational force. The difference in $δ_{\rm c}$ between our model and the fully matter dominated cosmological model is small at a low redshift and, hence, only the high mass tail of the mass function is affected by the magnetic fields. At a high redshift, on the other hand, the difference in $δ_{\rm c}$ becomes large enough to suppress the halo abundance over a wide range of mass scales. The halo abundance is reduced for instance by as large a factor as $\sim10^5$ at $z=9$.

description: We present a theory and computation method of radiation pressure from partially coherent light by establishing a coherent mode representation of the radiation forces. This is illustrated with the near field emitted from a Gaussian Schell model source, mechanically acting on a single cylinder with magnetodielectric behavior, or on a photonic molecule constituted by a pair of such cylinders. Thus after studying the force produced by a single particle, we address the effects of the spatial coherence on the bonding and anti-bonding states of two particles. The coherence length manifests the critical limitation of the contribution of evanescent modes to the scattered fields, and hence to the nature and strength of the electromagnetic fores, even when electric and/or magnetic partial wave resonances are excited.

description: Absence epilepsy is believed to be associated with the abnormal interactions between the cerebral cortex and thalamus. Besides the direct coupling, anatomical evidence indicates that the cerebral cortex and thalamus also communicate indirectly through an important intermediate bridge--basal ganglia. It has been thus postulated that the basal ganglia might play key roles in the modulation of absence seizures, but the relevant biophysical mechanisms are still not completely established. Using a biophysically based model, we demonstrate here that the typical absence seizure activities can be controlled and modulated by the direct GABAergic projections from the substantia nigra pars reticulata (SNr) to either the thalamic reticular nucleus (TRN) or the specific relay nuclei (SRN) of thalamus, through different biophysical mechanisms. Under certain conditions, these two types of seizure control are observed to coexist in the same network. More importantly, due to the competition between the inhibitory SNr-TRN and SNr-SRN pathways, we find that both decreasing and increasing the activation of SNr neurons from the normal level may considerably suppress the generation of SWDs in the coexistence region. Overall, these results highlight the bidirectional functional roles of basal ganglia in controlling and modulating absence seizures, and might provide novel insights into the therapeutic treatments of this brain disorder.

description: The purposes of this research study were: 1) to develop a Collaborative Learning Model with Virtual Team in u-Learning Environment using Creative Problem-solving Process(U-CCPS Model); 2) to evaluate a U-CCPS Model. The research procedures were divided into two phases. The first phase was to develop U-CCPS Model, and the second phase was to evaluate U-CCPS Model. The sample group in this study consisted of five experts using purposive sampling. Data were analyzed by arithmetic mean and standard deviation. The research findings were as follows: The U-CCPS learning Model consisted of five components as follows: 1) Input factors, 2) Process, 3) Control, 4) Output and 5) Feedback. The input factors consisted of four components as followed: 1) Objectives of U-CCPS Model, 2) Roles of Instructors, 3) Roles of learners and 4) Design of learning media. The process consisted of two components as followed: 1) Preparation before learning, and 2) Instructional management process. The experts agree that a U-CCPS Model was highest suitability.

description: We apply the time-delayed Pyragas control scheme to the dissipative Dicke model via a modulation of the atom-field-coupling. The feedback creates an infinite sequence of non-equilibrium phases with fixed points and limit cycles in the primary superradiant regime. We analyse this Hopf bifurcation scenario as a function of delay time and feedback strength, and determine analytical conditions for the phase boundaries.

description: The late-B magnetic chemically peculiar star CU Vir is one of the fastest rotators among the intermediate-mass stars with strong fossil magnetic fields. It shows a prominent rotational modulation of the spectral energy distribution and absorption line profiles due to chemical spots and exhibits a unique strongly beamed variable radio emission. Little is known about the magnetic field topology of CU Vir. In this study we aim to derive, for the first time, detailed maps of the magnetic field distribution over the surface of this star. We use high-resolution spectropolarimetric observations covering the entire rotational period. These data are interpreted using a multi-line technique of least-squares deconvolution (LSD) and a new Zeeman Doppler imaging code based on detailed polarised radiative transfer modelling of the Stokes I and V LSD profiles. This new magnetic inversion approach relies on the spectrum synthesis calculations over the full wavelength range covered by observations and does not assume that the LSD profiles behave as a single spectral line with mean parameters. We present magnetic and chemical abundance maps derived from the Si and Fe lines. Mean polarisation profiles of both elements reveal a significant departure of the magnetic field topology of CU Vir from the commonly assumed axisymmetric dipolar configuration. The field of CU Vir is dipolar-like, but clearly non-axisymmetric, showing a large difference of the field strength between the regions of opposite polarity. The main relative abundance depletion features in both Si and Fe maps coincide with the weak-field region in the magnetic map. Detailed information on the distorted dipolar magnetic field topology of CU Vir provided by our study is essential for understanding chemical spot formation, radio emission, and rotational period variation of this star.

description: In the present paper we obtain a new correlation inequality and use it for the purpose of extending the theory of the Almost Sure Local Limit Theorem to the case of lattice random sequences in the domain of attraction of a stable law. In particular, we prove ASLLT in the case of the normal domain of attraction of $α$--stable law, $α\in(1,2)$.

description: Dans le monde scolaire, nous ne pouvons pas négliger la place importante que prend l’apprentissage ainsi que l’utilisation de la table de multiplication. Il est vrai que nous sommes tous passés par cette étape lorsque nous étions élève. Grâce aux recherches que nous avons menées, l’apprentissage de la table de multiplication peut être optimisé par plusieurs éléments. En effet, de nombreux ouvrages relèvent que donner du sens améliore tout apprentissage. Dans notre travail, le sens est orienté vers la propriété de la commutativité de la multiplication. Par conséquent, notre problématique est la suivante : La mise en évidence de la commutativité permet-elle une restitution du répertoire multiplicatif mémorisé plus rapide et fiable ? Pour répondre à cette question, nous avons récolté des données de différentes manières, dans deux classes de 6H. Nous avons créé plusieurs tests qui ont été passés à différents moments. Nous avons notamment mené une leçon portant sur la mise en évidence de la commutativité.

description: Health and social care systems, primarily designed for people with single diseases rather than those with multimorbidity (two or more long-term conditions [LTCs]), are becoming more complex. With increases in the older population, a rise of multimorbidity and greater fragmentation in the care landscape, little is known about how multimorbidity affects the patient’s task to find appropriate care in the right place and at the right time (i.e. care navigation). Difficulties in care navigation have proven to cause delays in access and use of inappropriate services. For older individuals with a number of LTCs, there is an urgent need to support them in appropriately navigating the care system to maximise their health and wellbeing.Using a mixed method design, this study aims to map the personal care network (PCN) of older people (aged 55 years and over) with multimorbidity. It explores the use of Information and Communication Technologies (ICT) to support this patient group in finding their way through the care system. The research involves three stages, addressing the overall question: “Navigating the care system: what is feasible and acceptable with regard to the use of ICT to support older people with multimorbidity?”A scoping review brings together the limited literature on care navigation in older people with multimorbidity and identifies gaps in knowledge. The results demonstrate that navigating the care system is perceived to be a daunting task for many patients. Patients have to learn through experience, rather than being able to rely on systems and actors within the care environment. The gaps in knowledge and practice, identified in the scoping review, are the drivers of the second stage of the study. Stage two investigates from a patients’ perspective, the structure and composition of the PCN surrounding older people with multimorbidity. People and services (actors) involved in the care for this patient group are explored through

description: Crowd simulation is rapidly becoming a standard tool for evacuation planning and evaluation. However, the many crowd models in the literature are structurally different, and few have been rigorously calibrated against real-world egress data, especially in emergency situations. In this paper we describe a procedure to quantitatively compare different crowd models or between models and real-world data. We simulated three models: (1) the lattice gas model, (2) the social force model, and (3) the RVO2 model, and obtained the distributions of six observables: (1) evacuation time, (2) zoned evacuation time, (3) passage density, (4) total distance traveled, (5) inconvenience, and (6) flow rate. We then used the DISTATIS procedure to compute the compromise matrix of statistical distances between the three models. Projecting the three models onto the first two principal components of the compromise matrix, we find the lattice gas and RVO2 models are similar in terms of the evacuation time, passage density, and flow rates, whereas the social force and RVO2 models are similar in terms of the total distance traveled. Most importantly, we find that the zoned evacuation times of the three models to be very different from each other. Thus we propose to use this variable, if it can be measured, as the key test between different models, and also between models and the real world. Finally, we compared the model flow rates against the flow rate of an emergency evacuation during the May 2008 Sichuan earthquake, and found the social force model agrees best with this real data.

description: La libertà è in questione. Ciò può voler dire che, soprattutto a partire dall'Età Moderna, il pensiero occidentale ha riconosciuto nella libertà la propria questione, quel concetto ineludibile, senza la cui interrogazione l'etica e la politica, in particolare, neppure sarebbero pensabili. Ma che la libertà sia in questione, può significare anche che essa, oggi, conclusasi una fase del Moderno, vada messa in questione, vale a dire in discussione.

Thermodynamics of the unified dark fluid with fast transition

description: In the so-called unified dark fluid models, the dark sector gets simplified because dark matter and dark energy are replaced by a single fluid that behaves as the former at early times and as the latter at late times. In this short paper we analyze this class of models from the thermodynamic viewpoint. While the second law of thermodynamics is satisfied, the first two derivatives of the entropies of the apparent horizon and of the energy components suffer such a sharp oscillation that doubts are raised about the soundness of this class of models.
