Good practice for pupils learning English as an additional language; lessons from effective literacy teachers in inner city primary schools.

This article presents observations and discussion of the successful teaching of English to pupils, in English primary schools, for whom English is an additional language (EAL). It draws on research in Year 2 (6/7year old) classes in three inner-city primary schools carried out in 2003 and 2005. Three recognised, effective teachers of literacy were selected for case study; all worked in successful schools where results for literacy, measured by national tests, were in line with or better than national averages. Following analyses of lesson observations and interviews with the teachers, their Headteachers and the EAL co-ordinators in the schools, a number of common elements in their practice emerged. Discussion centres on how these pedagogical features supported effective learning environments for the early literacy development of bilingual children, and on the implications for the practice of teaching English to all pupils.

What do effective teachers of literacy do? Subject knowledge and pedagogical choices for literacy

This article explores the fine detail of practice by three teachers, recognised as effective teachers of literacy. All three were observed during nine literacy lessons, working with Year 2 (6/7 year olds) classes of successful inner-city primary schools in the South of England. Data collection took place in 2003, just as their schools were moving away from the early prescription of the National Literacy Strategy (NLS), and follow up visits were made in 2005. My initial interest had been in what these three teachers did with the NLS in order to motivate pupils and ensure high pupil attainment. Following observations, interviews and coding of teacher-pupil interaction, it became clear that The NLS Framework for Teaching (DfES, 2001) was not the driver of their success but a valuable vehicle for subtle and intuitive teacher behaviours that grew from a detailed understanding of how children develop as readers and writers. Implications for training student teachers to marry theoretical understanding with the expectations of a prescribed curriculum for literacy are discussed.

Are sulfurous soil amendments (S0, Fe(II)SO4, Fe(III)SO4) an effective tool in the restoration of heathland and acidic grassland after four decades of rock phosphate Fertilization?

This paper deals with the complex issue of reversing long-term improvements of fertility in soils derived from heathlands and acidic grasslands using sulfur-based amendments. The experiment was conducted on a former heathland and acid grassland in the U.K. that was heavily fertilized and limed with rock phosphate, chalk, and marl. The experimental work had three aims. First, to determine whether sulfurous soil amendments are able to lower pH to a level suitable for heathland and acidic grassland re-creation (approximately 3 pH units). Second, to determine what effect the soil amendments have on the available pool of some basic cations and some potentially toxic acidic cations that may affect the plant community. Third, to determine whether the addition of Fe to the soil system would sequester PO4− ions that might be liberated from rock phosphate by the experimental treatments. The application of S0 and Fe(II)SO4− to the soil was able to reduce pH. However, only the highest S0 treatment (2,000 kg/ha S) lowered pH sufficiently for heathland restoration purposes but effectively so. Where pH was lowered, basic cations were lost from the exchangeable pool and replaced by acidic cations. Where Fe was added to the soil, there was no evidence of PO4− sequestration from soil test data (Olsen P), but sequestration was apparent because of lower foliar P in the grass sward. The ability of the forb Rumex acetosella to apparently detoxify Al3+, prevalent in acidified soils, appeared to give it a competitive advantage over other less tolerant species. We would anticipate further changes in plant community structure through time, driven by Al3+ toxicity, leading to the competitive exclusion of less tolerant species. This, we suggest, is a key abiotic driver in the restoration of biotic (acidic plant) communities.

Pollinator conservation: the difference between managing for pollination services and preserving pollinator diversity

Our review looks at pollinator conservation and highlights the differences in approach between managing for pollination services and preserving pollinator diversity. We argue that ecosystem service management does not equal biodiversity conservation, and that maintaining species diversity is crucial in providing ecosystem resilience in the face of future environmental change. Management and policy measures therefore need to focus on species not just in human dominated landscapes but need to benefit wider diversity of species including those in specialised habitats. We argue that only by adopting a holistic ecosystem approach we can ensure the conservation and sustainable use of biodiversity and ecosystem services in the long-term.

Basic Income, Republican Freedom, and Effective Market Power

This article examines republican arguments for a basic income that turn on a right to exit the labour market. It gives criteria for the maintenance of republican freedom in markets, arguing that a right to exit or effective market power will guarantee republican freedom in markets. The article then considers whether a basic income is either sufficient or necessary to protect republican freedom both in labour markets and elsewhere. If a basic income is necessary to protect republican freedom in the labour market, I argue it is not sufficient to protect that freedom elsewhere. If citizens lack the means to maintain their republican freedom in the labour market, then there may be other spheres of life where they are vulnerable to subordination, whether or not they have a basic income. Some sociological evidence on cultural consumption patterns is presented.

Legal and regulatory barriers to effective public-private partnership governance in Kazakhstan

Purpose – The purpose of this paper is to provide a critical assessment of legal and regulatory impediments to effective governance of public-private partnerships (PPPs) in Kazakhstan. Design/methodology/approach – The qualitative study develops propositions from the PPP literature and then tests them against findings from in-depth interviews. Interviewees have been selected by a purposeful sampling from PPP projects in Kazakhstan as well as from national and regional PPP centres. Findings – The identified barriers to effective PPP management include irregularities in the PPP legal framework, such as lack of legal definition of a PPP and controversy with the government guarantee’s legal status for its long-term payments to partnerships; bureaucratic tariff setting for partnership services; non-existent opportunity for private asset ownership; and excessive government regulation of PPP workers’ wage rates. Practical implications – The partners’ opposing perspectives on a number of PPP issues show that management needs to identify and carefully reconcile stakeholder values in a partnership in order to achieve more effective PPP governance. Practitioners, particularly those in the public agencies, have to be concerned with ways to reduce the government overregulation of the private operators, which is likely to result in greater PPP flexibility in management and, ultimately, higher efficiency in delivering the public services. Originality/value – By elucidating multiple examples of overregulation and PPPs’ inefficiency, the paper demonstrates that the government dominance in PPP management is conceptually inappropriate. Instead, the government should adopt the concept of co-production and manage its relations with the private sector partner in a collaborative fashion.

Effective interaction between monolayers of block copolymer compatiblizer in a polymer blend

The stability of ternary blends of two immiscible homopolymers and a block copolymer compatiblizer depends crucially on the effective interaction between the copolymermonolayers that form between the unlike homopolymer domains. Here, the interaction is calculated for blends involving A and B homopolymers of equal size with ABABdiblock copolymers of symmetric composition using both self-consistent field theory (SCFT) and strong-segregation theory (SST). If the homopolymers are larger than the copolymer molecules, an attractive interaction is predicted which would destroy the blend. This conclusion coupled with considerations regarding the elastic properties of the monolayer suggests that the optimum size of the homopolymer molecules is about 80% that of the copolymer molecule. A detailed examination of the theory demonstrates that the attraction results from the configurational entropy loss of the homopolymer molecules trapped between the copolymermonolayers. We conclude by suggesting how the monolayers can be altered in order to suppress this attraction and thus improve compatiblization.
