Synthesis of a novel UV-curable prepolymer neopentyl glycol diglycidyl ether diacrylate and its cured film tensile property

A novel UV-curable prepolymer neopentyl glycol diglycidyl ether diacrylate(NPGGEA)was synthesized by using neopentyl glycol diglycidyl ether(NPGGE)and acrylic acid(AA)as starting materials, N, N-dimethylbenzylamine as catalyst and p-hydroxyanisole as inhibitor. The optimum synthetic conditions were taken as follows: The concentration of N,N-dimethylbenzylamine, 0.80% of reactants; the concentration of p-hydroxyanisole, 0.3% of reactants; the reaction temperature, 90-110℃; the molar ratio of NPGGE to AA, 1:2.2. Meanwhile, 1-hydroxycyclohexyl phenyl ketone of a UV-cured initiator was added to the synthesized NPGGEA to prepare a kind of UV-cured coating. Mechanical properties of the UV-cured films were determined, giving 28.75 MPa of tensile strength, 923.82 MPa of Young‘s modulus and 5.51% of elongation at tear.     

The cultural understanding of inclusion and its development within a centralised system

This paper discusses inclusion in relation to centralised systems, in particular the constraints central control makes upon decisions at school level. The discussion is empowered by an evaluative case study research undertaken to understand the development of inclusion in contexts where flexible teaching and curriculum change are sometimes hard to find. In particular, based on a systems approach, this research describes and evaluates an attempt in a Greek primary school to implement inclusive practices, aiming to analyse the problems and prospects of inclusion in a highly centralised system, entirely controlled by the Ministry of Education. The inclusive practices developed in this school were based on a collaborative teacher model, offering new roles to mainstream teachers. The research data come from a diary, group interviews, classroom and meetings observations, and document analysis. The study reveals several obstacles to inclusion, besides the good practices which promote it. The main argument is that a centralised system favours the integration of students with disabilities more than their inclusion.

Assessing the social and affective outcomes of inclusion

The systematic assessment of the social and affective outcomes of inclusion has been lagging behind the assessment of academic outcomes. This is particularly problematic in view of research evidence supporting concerns about peer rejection and bullying. In this article, Norah Frederickson and Elizabeth Simmonds, of University College London, and Lynda Evans and Chris Soulsby, from Foxwood Special School, report their evaluation of the social and affective outcomes of a special- mainstream school inclusion initiative that places particular emphasis on peer preparation. Measures completed by pupils were used to assess peer group inclusion, social behaviour, bullying and feelings of belonging at school. Results showed that pupils who had transferred from special to mainstream schools experienced positive social outcomes and none experienced peer group rejection. However, results were less positive for mainstream pupils with special educational needs and the authors discuss possibilities for development. Trends in peer reports of bullying suggest that there is no room for complacency and that ongoing monitoring is required.

Conceptualisations of disability and inclusion: perspectives of educators of young children

This grounded theory study explores beliefs about disability and inclusion from the perspectives of educators of young children in their respective roles as elementary school teachers and early childhood educators, in Ontario, Canada. The social relational model described by Reindal is used as a theoretical framework for interviews with four educators. The interview data provide a theory of educators' beliefs and show the relationship of the beliefs to their practice. Implications based on the theory are presented for both policy and professional development.

Herding cats or getting heard: The SENCo–teacher dynamic and its impact on teachers' classroom practice

This article is based on two key findings of doctoral research into the impact that Special Educational Needs Coordinators (SENCos) in England have on teachers' skills when addressing the needs of children with SEN in mainstream primary schools. I use data from questionnaires and interviews with SENCos, teachers and headteachers to argue that key indicators for successful teaching of children with SEN include SENCos skilling teachers in their roles as ‘agents of change’ in relation to SENCos' views of their teaching colleagues, as well as the evolving nature of their own professional identity.
