Social effects of collaborative learning in primary schools

There is conflicting evidence on whether collaborative group work leads to improved classroom relations, and if so how. A before and after design was used to measure the impact on work and play relations of a collaborative learning programme involving 575 students 9e12 years old in single- and mixed-age classes across urban and rural schools. Data were also collected on student interactions and teacher ratings of their group-work skills. Analysis of variance revealed significant gains for both types of relation. Multilevel modelling indicated that better work relations were the product of improving group skills, which offset tensions produced by transactive dialogue, and this effect fed through in turn to play relations. Although before intervention rural children were familiar with each other neither this nor age mix affected outcomes. The results suggest the social benefits of collaborative learning are a separate outcome of group work, rather than being either a pre-condition for, or a direct consequence of successful activity, but that initial training in group skills may serve to enhance these benefits.

Labour Law as Human Rights Law: A Critique of the Use of ‘Dignity’ by Freedland and Kountouris

In their recent book, The Legal Construction of Personal Work Relations, Mark Freedland and Nicola Kountouris present an ambitious study of the personal scope of (what they would not want to call) ‘employment’ law. The book does this within a broader argument that calls for the reconceptualization of labour law as a whole, and it is this broader argument on which I shall focus in this chapter. Their aim, in urging us to see labour law through the lens of ‘dignity’ is to bring labour law and human rights law into closer alignment than has sometimes been the case in the past. Increasingly, dignity is seen as providing a, sometimes the, foundation of human rights law, particularly in Europe. I shall suggest that whilst the aim of constructing a new set of foundations for labour law is a worthy and increasingly urgent task, the concepts on which Freedland and Kountouris seek to build their project pose significant difficulties. In particular, their espousal of ‘dignity’ presents problems that must be addressed if their reconceptualization is not to prove a blind alley.

Experimental Reconstruction of Work Distribution and Study of Fluctuation Relations in a Closed Quantum System

We report the experimental reconstruction of the nonequilibrium work probability distribution in a closed quantum system, and the study of the corresponding quantum fluctuation relations. The experiment uses a liquid-state nuclear magnetic resonance platform that offers full control on the preparation and dynamics of the system. Our endeavors enable the characterization of the out-of-equilibrium dynamics of a quantum spin from a finite-time thermodynamics viewpoint.

Panning for Gold: The Standardizing Work of Filling “Autistic” Shells – Using institutional ethnography to explore textually mediated health relations in the diagnostic process of autism.

Health reform practices in Canada and elsewhere have restructured the purpose and use of diagnostic labels and the processes of naming such labels. Diagnoses are no longer only a means to tell doctors and patients what may be wrong and indicate potential courses of treatment; some diagnoses activate specialized services and supports for persons with a disability and those who provide care for them. In British Columbia, a standardized process of diagnosis with the outcome of an autism spectrum disorder gives access to government provided health care and educational services and supports. Such processes enter individuals into a complex of text mediated relations, regulated by the principles of evidence-based medicine. However, the diagnosis of autism in children is notoriously uncertain. Because of this ambiguity, standardizing the diagnostic process creates a hurdle in gaining help and support for parents who have children with problems that could lead to a diagnosis on the autism spectrum. Such processes and their organizing relations are problematized, explored and explicated below. Grounded in the epistemological and ontological shift offered by Dorothy E. Smith (1987; 1990a; 1999; 2005), this article reports on the findings of an institutional ethnographic study that explored the diagnostic process of autism in British Columbia. More specifically, this article focuses on the processes involved in going from mothers talking from their experience about their childrens problems to the formalized and standardized, and thus “virtually” produced, diagnoses that may or may not give access to services and supports in different systems of care. Two psychologists, a developmental pediatrician, a social worker – members of a specialized multidisciplinary assessment team – and several mothers of children with a diagnosis on the autism spectrum were interviewed. The implications of standardizing the diagnosis process of a disability that is not clear-cut and has funding attached are discussed. This ethnography also provides a glimpse of the implications of current and ongoing reforms in the state-supported health care system in British Columbia, and more generally in Canada, for people’s everyday doings.

Professional Educational Psychology and Community Relations Education in Northern Ireland.

This article provides an account of practice-based research of, at least, one-star quality in terms of its contribution to both theory and practice. Aimed at practitioner (as opposed to academic) psychologists, the article addresses a dimension of the practitioner role that has remained silent in the literature. The article makes creative and original connections between school effectiveness, school improvement and education in a divided society. Post 11th September, the article was described as being highly original, significant and relevant to all practising educational psychologists. Concrete evidence for this is gained from, eg: hits on the online electronic version (2002-2003 Annual Report of the Association of Educational Psychologists), citations in reviews of research, and author invitations to present his work at UK and international practitioner psychology conferences. The article is published in the premier journal reporting on quality applied educational research and practice within the United Kingdom and beyond.

Towards variance-matrix characterization of complementarity relations in a continuous variable system

We discuss complementarity relations in a bipartite continuous variable system. Building up from the work done on discrete d-dimensional systems, we prove that for symmetric two-mode states, quantum complementarity relations can be put in a simple relation with the elements of the variance matrix. When this condition is not satisfied, such a connection becomes non-trivial. Our investigation is the first step towards an operative characterization of the complementarity in a scenario that has not been investigated so far.

Organisational Self-Evaluation and Teacher Education for Community Relations in a Transforming Society?

During 2004, the School of Education at the University of Ulster embarked on an innovative three-year project designed to embed community relations objectives within initial teacher education. With the advent of more peaceful times in Northern Ireland, this was a precipitous time for initial teacher educators to review the preparation given to beginner teachers for teaching in an increasingly pluralist society emerging from conflict. The present paper reports on one very specific and time-limited element of the broader project. That is, development work designed to investigate the possibilities of using processes of self-review and evaluation as a lever for improvements in initial teacher education for community relations. Following a brief contextualisation, the background to, and the development of, a set of materials designed to support rigorous and systematic self-review of all aspects of provision in a university-based initial teacher education department is described. The Community Relations Index for Initial Teacher Education (Cr-ITE) was envisaged as being of use to initial teacher education establishments in order to help teacher educators take responsibility for rigorous learning from their practice, whilst placing inclusive values at the centre of organisational development. The final section includes further critical reflection on the role of organisational self-review in transforming teacher education for inclusion in a society emerging from longstanding communal conflict.

Part-whole relations between food webs and the validity of local food-web descriptions

This work analyzes the relationship between large food webs describing potential feeding relations between species and smaller sub-webs thereof describing relations actually realized in local communities of various sizes. Special attention is given to the relationships between patterns of phylogenetic correlations encountered in large webs and sub-webs. Based on the current theory of food-web topology as implemented in the matching model, it is shown that food webs are scale invariant in the following sense: given a large web described by the model, a smaller, randomly sampled sub-web thereof is described by the model as well. A stochastic analysis of model steady states reveals that such a change in scale goes along with a re-normalization of model parameters. Explicit formulae for the renormalized parameters are derived. Thus, the topology of food webs at all scales follows the same patterns, and these can be revealed by data and models referring to the local scale alone. As a by-product of the theory, a fast algorithm is derived which yields sample food webs from the exact steady state of the matching model for a high-dimensional trophic niche space in finite time.

Do Recessions Transform Work and Employment? Evidence from Ireland

Two contrasting views tend to dominate the literature on the impact of recessions on employment. One view is that recessions amount to a ‘critical conjuncture’ for work and employment systems, a time when firms try to transform radically existing employment models. The alternative perspective is that firms, constrained mostly by the forces of path dependency, seek to adjust to the immediate or short-term pressures of the recession but otherwise maintain the established way of organizing the employment relationship. The purpose of this article is to contribute to this literature by reporting the findings of a major study of the effects of the recession on work and employment in firms based in Ireland. The main finding to emerge from the study is that firms mostly have made improvised adaptations in response to the crisis and have shied away from far-reaching transformational strategies.
