High Seas Fisheries Management Gets Low Marks
Fishing on the high seas—areas beyond the 200-nautical-mile jurisdiction of coastal states—is increasing, largely driven by advanced vessel and gear technology, which facilitates fishing far from shore. High seas fisheries are overseen by various regional fisheries management organizations (RFMOs)—intergovernmental bodies made up of nations that have agreed to cooperatively manage fish stocks beyond their national boundaries. Although RFMOs were established to manage and conserve high seas fish stocks, these populations are declining.To illuminate any contradiction between stated management goals and the status of managed fish stocks, Sarika Cullis-Suzuki and Daniel Pauly, researchers at the University of British Columbia, developed a way to score the performance of RFMOs "on paper" versus "in practice." Their results show that on paper, RFMOs are not meeting best practice standards and, in practice, are failing to halt the dramatic declines of fish stocks for which they have management responsibility

The quality of group childcare settings used by 3-4 year old children in Sure Start local programme areas and the relationship with child outcomes (Research report DFE-RR068)
"Influenced by research indicating long-term benefits of early childhood programmes for disadvantaged children, the Government of the time set up Sure Start Local Programmes (SSLPs) from 1998 to reduce child poverty and social exclusion. By 2004, 524 SSLPs targeted families with children 0-4 years of age in the 20% most deprived communities. In 2005 it was decided to develop SSLPs further by turning them into children’s centres and roll out the programme nationally, ensuring that comprehensive early education and family support services are available for every community. The National Evaluation of Sure Start has been undertaking research relevant to the development of SSLPs since 2001. This part of the study focuses on 150 SSLP areas from the first four rounds of SSLPs, which are all in deprived areas." - Page iii
Biotechnology and Plant Productivity
Author Institution: Dept. of Biology, Case Western Reserve UniversityThere is considerable potential for the application of biotechnology and genetic engineering to plant productivity. The basic manipulations for the isolation of genes and their transfer between species are well documented in model systems. However, more information is required concerning the basic processes governing plant productivity at the molecular level before practical applications can be achieved. In this paper, detailed consideration is given to (1) the use of restriction fragment polymorphisms as genetic markers, and (2) the molecular basis of hybrid vigor. In both cases it is clear that these techniques will be adjuncts to the already established methods for plant improvement but with far reaching potential for the future
The Morphology and Misfit Dislocation Formation Characteristics of Strained Heteroepitaxial Layers: Ex Situ and In Situ Growth Studies
Under certain regimes of heteroepitaxial layer growth, misfit stresses can lead to very significant distortions in interface morphology, which can influence strain relief and subsequent misfit dislocation introduction. These phenomena have been clearly demonstrated in the case of SiGe/Si heteroepitaxy and the way in which surface SiGe growth ripples are accompanied by strain waves has been established. The ripples provide partial elastic relief of the layer misfit stress in a manner which has been correlated with theoretical expectations. The local stress variations ultimately may influence the formation and disposition of misfit dislocations in the strained layer structures. The present paper reviews primarily our understanding of these growth characteristics. It also outlines current in situ synchrotron growth studies which exploit real-time X-ray topography and diffraction to probe heteroepitaxial strain-relief processes

Children's relationships with their physical school: Considerations of primary architecture and furniture design in a social and cultural context
This thesis was submitted for the degree of Doctor of Philosophy and was awarded by Brunel University on behalf of Buckinghamshire New University.In recent years substantial investment has been made to replace or refurbish state schools in England and Wales and, although research has unsuccessfully sought to prove its contribution, the discipline of Design continues to be identified as a facilitator of educational transformation.
Results to date, however, are mixed and there is an evident failing at the design briefing stage to understand how children interact with their educational settings and, notably, an avoidance of direct challenge to the primary school classroom and its practice. In response, this thesis asks how the social and cultural study of children’s relationships with their physical school can suggest a meaningful approach to primary school architecture and furniture design.
A model of well-being is developed to clarify misused terminology and to present a realistic expectation of design in which the contradictory goals of inclusion and the development of the individual are appraised. Sitting within a diverse grounded methodology, the concept of belonging is then explored as a basis for evaluating the contribution of different aspects of the physical school to children’s well-being.
The primary school environments studied were found to limit the possibilities of a child’s well-being. School architecture through to classroom wall displays were complicit in restricting physical and social expression in favour of school organisation and, furthermore, the central child-teacher relationship was found to be unnecessarily devalued by behavioural concerns derived from the setting.
By ethically interpreting the rich variety of children’s voices, priorities for what is coined here as child-teacher centred design are established and a clear relationship between architecture and furniture is offered. The thesis recommends that architecture continues to perform a protective classroom role to support objectives of inclusion whilst school furniture supports more affective, individualistic goals through less prescriptive and more varied settings for learning
Optimal strategies for regional cultivar testing
In undertaking cultivar trials, the variability of the response of the cultivars to the different environments in which they are grown introduces the possibility of release errors and non‐release errors in the decisions made on the basis of the trial results. In this article a model is developed that accounts for the economic costs of those errors as well as the costs of operating the trials, and enables the features of the optimal cultivar testing program to be identified. The model is illustrated by application to wheat cultivar trials in central and southern NSW.Crop Production/Industries,
