Exploring the effects of a universal classroom management training programme on teacher and child behaviour: a group randomised controlled trial and cost analysis

Teachers frequently struggle to cope with conduct problems in the classroom. The aim of this study was to assess the effectiveness of the Incredible Years Teacher Classroom Management Training Programme for improving teacher competencies and child adjustment. The study involved a group randomised controlled trial which included 22 teachers and 217 children (102 boys and 115 girls). The average age of children included in the study was 5.3 years (standard deviation = 0.89). Teachers were randomly allocated to an intervention group (n = 11 teachers; 110 children) or a waiting-list control group (n = 11; 107 children). The sample also included 63 ‘high-risk’ children (33 intervention; 30 control), who scored above the cut-off (>12) on the Strengths and Difficulties Questionnaire for abnormal socioemotional and behavioural difficulties. Teacher and child behaviours were assessed at baseline and 6 months later using psychometric and observational measures. Programme delivery costs were also analysed. Results showed positive changes in teachers’ self-reported use of positive classroom management strategies (effect size = 0.56), as well as negative classroom management strategies (effect size = −0.43). Teacher reports also highlight improvements in the classroom behaviour of the high-risk group of children, while the estimated cost of delivering the Incredible Years Teacher Classroom Management Training Programme was modest. However, analyses of teacher and child observations were largely non-significant. A need for further research exploring the effectiveness and cost-effectiveness of the Incredible Years Teacher Classroom Management Training Programme is indicated.

Skolan i livet - livet i skolan : Några illitterata invandrarkvinnor lär sig tala, läsa och skriva på svenska som andraspråk

Many immigrants in Sweden have not had the chance to learn to read and write, for various reasons. In Sweden, literacy is a prerequisite to being able to function in the cultural community, and for many immigrants this is the first time that they experience their inability to read and write as a handicap or see themselves as “illiterate”. The aim of this study is to use a socio-cultural, second language and gender approach to describe, analyse and understand how a number of adult, illiterate, immigrant women experience their situation when they are expected to simultaneously learn to speak, read and write Swedish. The study focuses on two literacy groups in two Swedish municipalities. In one of the groups I act as both teacher and researcher. The thesis is a case study of the learning process of five illiterate immigrant women in Sweden. The results are based on interviews, carried out with the help of an interpreter, and observation of teaching and texts ritten by the students. The study is based on the assumption that human learning is an activity that takes place in a cultural community in a social context. When learning a language, the language is simultaneously the tool that facilitates social communication and the object of the learning process. The study shows that cultural communities influence the women in different ways. Gender structures are firmly planted in a patriarchal value system, which means that women are seen as inferior to men, and women are expected to “meet the demands of others”. The women have no time to study at home, as their household duties are prioritised. However, there are subtle indications that there is a wish to change the situation in accordance with Swedish values and norms. This can be seen in the Swedish for Immigrants (SFI) lessons. As they have little contact with Swedes, school is the only arena in which they have a chance to use Swedish. They are positive towards teaching and school as an institution. Here they are able to develop an alternative identity. The study also shows that teaching in the literacy groups is to a great extent based on a technical approach, in which the teacher tries to elicit a correct answer from the students. Social interaction involving contemplation and negotiation is either not included or not prioritised. the women’s experience and knowledge is not made use of. There are,however, occasions when collaborative discussions take place between the teacher and students. On these occasions an exchange of experiences takes place. Learning is based on the students’ own experiences and thoughts. Linguistic concepts gain meaning in the collaborative discussion. Initially the concepts may be unclear, but the group works on them together, adapting and adjusting them until they finally make sense. Finally, I conclude that women immigrants bring their own socio-cultural values and experience to the school situation, which affects their learning process to varying degrees. Furthermore, immigrant women need more time at school, as it is the only arena in which they can spend time on studying and personal development. another conclusion is that the school must become a learning community that recognises the immigrants’ cultures, makes use of the students’ experience and allows the students to participate in collaborative discussions, so that they can develop their ability to speak, read and write Swedish.

Extracurricular language activities in higher education: Perspectives of teachers and students

This Master’s thesis researches the topic “Extracurricular language activities in higher education: Perspectives of teachers and students”. In the light of several learning theories, namely, Self-Determination Theory, Social Learning Theory and Incidental Learning Theory, extracurricular participation in language related activities is studied. The main aims of the research are as follows: to study how extracurricular language activities can be organized and supported by the education institution; to investigate how such activities can promote the participants’ learning; and, to research how these activities can be developed and improved in the future. Due to the qualitative character of this research, the empirical data collected through interviews and their thematic analysis allow to study the participants’ perceptions on the above-mentioned issues. Among other results of the research, it can be noted that the organizers of extracurricular language activities and the participants of the activities may have different perspectives on the aims of the activities, as well as their advantages. Additionally, it has been found that the participants of activities would often speak on certain categories that imply the connection to some learning theories, which allows to hypothesize that some learning could be observed in those participants, following participation in extracurricular activities. This is an implication for further research in the area, which can focus on correlations between participation in extracurricular language activities and learning outcomes of the participants.

Study and analysis of the waves and currents interaction phenomena

Interaction of ocean waves, currents and sea bed roughness is a complicated phenomena in fluid dynamic. This paper will describe the governing equations of motions of this phenomena in viscous and nonviscous conditions as well as study and analysis the experimental results of sets of physical models on waves, currents and artificial roughness, and consists of three parts: First, by establishing some typical patterns of roughness, the effects of sea bed roughness on a uniform current has been studied, as well as the manning coefficient of each type is reviewed to find the critical situation due to different arrangement. Second, the effect of roughness on wave parameters changes, such as wave height, wave length, and wave dispersion equations have been studied, third, superimposing, the waves + current + roughness patterns established in a flume, equipped with waves + currents generator, in this stage different analysis has been done to find the governing dimensionless numbers, and present the numbers to define the contortions and formulations of this phenomena. First step of the model is verified by the so called Chinese method, and the Second step by the Kamphius (1975), and third step by the van Rijn (1990) , and Brevik and Ass ( 1980), and in all cases reasonable agreements have been obtained. Finally new dimensionless parameters presented for this complicated phenomena.

Spatial and temporal interaction between sediment and microphytobenthos in a temperate estuarine macro-intertidal bay

Intertidal flats of the estuarine macro-intertidal Baie des Veys (France) were investigated to identify spatial features of sediment and microphytobenthos (MPB) in April 2003. Gradients occurred within the domain, and patches were identified close to vegetated areas or within the oyster-farming areas where calm physical conditions and biodeposition altered the sediment and MPB landscapes. Spatial patterns of chl a content were explained primarily by the influence of sediment features, while bed elevation and compaction brought only minor insights into MPB distribution regulation. The smaller size of MPB patches compared to silt patches revealed the interplay between physical structure defining the sediment landscape, the biotic patches that they contain, and that median grain-size is the most important parameter in explaining the spatial pattern of MPB. Small-scale temporal dynamics of sediment chl a content and grain-size distribution were surveyed in parallel during 2 periods of 14 d to detect tidal and seasonal variations. Our results showed a weak relationship between mud fraction and MPB biomass in March, and this relationship fully disappeared in July. Tidal exposure was the most important parameter in explaining the summer temporal dynamics of MPB. This study reveals the general importance of bed elevation and tidal exposure in muddy habitats and that silt content was a prime governing physical factor in winter. Biostabilisation processes seemed to behave only as secondary factors that could only amplify the initial silt accumulation in summer rather than primary factors explaining spatial or long-term trends of sediment changes.

The Emergence of Spanish Impressionism and its Interaction with French Impressionism in Music at the Turn of the Twentieth Century: selections from the solo and collaborative piano repertoire

French Impressionism is a term which is often used in discussing music originating in France towards the end of the nineteenth century. The term Spanish Impressionism could also be used when discussing Spanish music written by the Spanish composers who studied and worked in Paris at the same time as their French counterparts. After all, Spanish music written during this time exhibits many of the same characteristics and aesthetics as French music of the same era. This dissertation will focus on the French and Spanish composers writing during that exciting time. Musical impressionism emphasizes harmonic effects and rhythmic fluidity in the pursuit of evocative moods, sound pictures of nature or places over the formalism of structure and thematic concerns. The music of this time is highly virtuosic as well as musically demanding, since many of the composers were brilliant pianists. My three dissertation recitals concentrated on works which exhibited the many facets of impressionism as well as the technical and musical challenges. The repertoire included selections by Spanish composers Manuel de Falla, Isaac Albéniz, Enrique Granados, Joaquín Turina, and Joaquín Rodrigo and French composers Claude Debussy and Maurice Ravel. The recitals were on April 30, 2013, February 23, 2014 and October 11, 2015. They included solo piano works by Granados and Albéniz, vocal works by Debussy, Ravel, de Falla, Turina and Rodrigo, piano trios by Granados and Turina, instrumental duos by Debussy, Ravel and de Falla, and a two-piano work of Debussy transcribed by Ravel. All three recitals were held in Gildenhorn Recital Hall at the University of Maryland and copies of this dissertation and recordings of each recital may be found through the Digital Repository at the University of Maryland (DRUM).

Three-dimensional kinetic simulations of active suspensions: effect of chemotaxis and steric interaction

In this work, the effects of chemotaxis and steric interactions in active suspensions are analyzed by extending the kinetic model proposed by Saintillan and Shelley [1, 2]. In this model, a conservation equation for the active particle configuration is coupled to the Stokes equation for the flow arising from the force dipole exerted by the particles on the fluid. The fluid flow equations are solved spectrally and the conservation equation is solved by second-order finite differencing in space and second-order Adams-Bashforth time marching. First, the dynamics in suspensions of oxytactic run-and-tumble bacteria confined in thin liquid films surrounded by air is investigated. These bacteria modify their tumbling behavior by making temporal comparisons of the oxygen concentration, and, on average, swim towards high concentrations of oxygen. The kinetic model proposed by Saintillan and Shelley [1, 2] is modified to include run-and-tumble effects and oxygentaxis. The spatio-temporal dynamics of the oxygen and bacterial concentration are analyzed. For small film thicknesses, there is a weak migration of bacteria to the boundaries, and the oxygen concentration is high inside the film as a result of diffusion; both bacterial and oxygen concentrations quickly reach steady states. Above a critical film thickness (approximately 200 micron), a transition to chaotic dynamics is observed and is characterized by turbulent-like 3D motion, the formation of bacterial plumes, enhanced oxygen mixing and transport into the film, and hydrodynamic velocities of magnitudes up to 7 times the single bacterial swimming speed. The simulations demonstrate that the combined effects of hydrodynamic interactions and oxygentaxis create collective three-dimensional instabilities which enhances oxygen availability for the bacteria. Our simulation results are consistent with the experimental findings of Sokolov et al. [3], who also observed a similar transition with increasing film thickness. Next, the dynamics in concentrated suspensions of active self-propelled particles in a 3D periodic domain are analyzed. We modify the kinetic model of Saintillan and Shelley [1, 2] by including an additional nematic alignment torque proportional to the local concentration in the equation for the rotational velocity of the particles, causing them to align locally with their neighbors (Doi and Edwards [4]). Large-scale three- dimensional simulations show that, in the presence of such a torque both pusher and puller suspensions are unstable to random fluctuations and are characterized by highly nematic structures. Detailed measures are defined to quantify the degree and direction of alignment, and the effects of steric interactions on pattern formation will be presented. Our analysis shows that steric interactions have a destabilizing effect in active suspensions.

Structural and functional interaction between polyamine related molecules and biological membranes

Changes induced by PA on nucleic acid (NA) conformation and synthesis is proven to be a major reason for PA essentiality (1-3). However, PA interactions with other polyanions, for instance polyanionic membrane lipid bilayers and glyosaminoglycans have received less attention (3-4). The functional importance of these interactions still is an obscure but interesting area of cell and molecular biology, especially in mammalian cells for which specific PA transport systems are not fully characterized (5). In mammals, activity and turnover of the polyamine (PA) synthesis key enzyme is controlled by a set of proteins: Antizymes (OAZ1-3) and antizyme inhibitors (AZIN1 and 2). It is demonstrated that AOZ modulate polyamine uptake (6), and that PA transport to mitochondria is linked to the respiratory chain state and modulates mitochondrial permeability transition (7). Antizyme expression variants have been located in mitochondria, being proposed as a proapoptotic factor (7-8). AZIN 2 is only expressed in a reduced set of tissues that includes mast cells, where it is associated to mast cell granules membrane (9). This fact, together to the abnormalities observed in bone marrow derived mast cell granules when they are differentiated under restricted PA synthesis conditions (10 and unpublished results), point out to important roles of PA and their related proteins in structure and function of mast cell granules. We will also present novel biophysical results on tripartite interactions of PA that remark the interest of the characterization of PA interactions with lipid bilayers for biomedicine and biotechnology. Thus, the information reported in this paper integrates previously reported information with our still unpublished results, all indicating that PA and their related proteins also are important factors for structure and dynamics of biological membranes and their associated functions essential in human physiology; for instance, solute interchange with the environment (uptake and secretion), oxidative metabolism and apoptosis. The importance of these involved processes for human homeostasis claim for further research efforts. 1.

Staff and students co-creating curricula in UK higher education: exploring process and evidencing value

Student engagement in learning and teaching is receiving a growing level of interest from policy makers, researchers, and practitioners. This includes opportunities for staff and students to co-create curricula, yet there are few examples within current literature which describe and critique this form of staff-student collaboration (Bovill (2013a), Healey et al (2014), Cook-Sather et al (2014). The competing agendas of neoliberalism and critical, radical pedagogies influence the policy and practice of staff and students co-creating curricula and, consequently, attempt to appropriate the purpose of it in different ways. Using case-based research methodology, my study presents analysis of staff and students co-creating curricula within seven universities. This includes 17 examples of practice across 14 disciplines. Using an inductive approach, I have examined issues relating to definitions of practice, conceptualisations of curricula, perceptions of value, and the relationship between practice and institutional strategy. I draw upon an interdisciplinary body of literature to provide the conceptual foundations for my research. This has been necessary to address the complexity of practice and includes literature relating to student engagement in learning and teaching, conceptual models of curriculum in higher education, approaches to evidencing value and impact, and critical theory and radical pedagogies. The study makes specific contributions to the wider scholarly debate by highlighting the importance of dialogue and conversational scholarship as well as identifying with participants what matters as well as what works as a means to evidence the value of collaborations. It also presents evidence of a new model of co-creating curricula and additional approaches to conceptualising curricula to facilitate collaboration. Analysis of macro and micro level data shows enactment of dialogic pedagogies within contexts of technical-rational strategy formation and implementation.
