    The mainstream primary classroom as a language-learning environment for children with severe and persistent language impairment - implications of recent language intervention research

    Get PDF
    Many UK children with severe and persistent language impairment (SLI) attend local mainstream schools. Although this should provide an excellent language-learning environment, opportunities may be limited by difficulties in sustaining time-consuming, child-specific learning activities; restricted co-professional working, and the complex classroom environment. Two language intervention studies in mainstream Scottish primary schools showed children with SLI receiving intervention from speech and language therapists (SLTs) or their assistants made more progress in expressive language than similar children receiving intervention from education staff. Potential reasons for this difference are sought in the amount of tailored language-learning activity undertaken; how actively school staff initiated contact with SLTs; and the language demands of the classroom. Tailored language learning appears to be a differentiating factor. A language support model, reflecting views of teachers and SLTs about encouraging language development for children with SLI within the ecology of the mainstream primary classroom, is also outlined

    Author David H. Ellis and illustrator N. John Schmitt deliver precisely what is promised in Behavior of the Golden Eagle: An Illustrated Ethogram. This “little volume,” as the author coins it, represents a single source for defining, identifying, and describing behaviors of the Golden Eagle (Aquila chrysaetos). With the inclusion of Schmitt’s exceptional drawings, the book is a piece of art, as well as the most useful manual describing Golden Eagle behaviors. Nearly four decades earlier, Ellis (1979) authored the very first Golden Eagle ethogram—the set of repeated standard behaviors for a species called action patterns—and in his new book, he has now synthesized and refined these descriptions to provide the true essence of the species in a format that is widely accessible and useful for many other species. Ellis has published more than 100 papers on birds of prey and has studied Golden Eagles across the world in their extensive northern circum-hemispheric range. As author of Enter the Realm of the Golden Eagle (Ellis 2013), he collected and contributed to a nearly 500-page non-fictionalanthology of accounts of the Golden Eagle in its habitats around the world. Schmitt, a decorated wildlife artist and biologist, specializes in scientifically accurate depictions of birds. Among other products, his artwork is highlighted in two field guides on raptors in different parts of the world (Clark 1979, Clark and Schmidt 2017). In Ellis and Schmitt, we see a pair of highly qualified individuals collaborating to produce a remarkably unique view of Golden Eagles and their behaviors

    A practice based learning environment for engineering students: Acquiring competencies for working on advanced manufacturing engineering

    No full text
    This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.In this thesis the author describes the design and operation of a learning environment aimed at imparting technical, technological and managerial knowledge, developing understanding of the underlying issues and enhancing team work skills for an advanced technology future. He offers an analysis of learning, education and training and compares group work with individual tasks, presents a major case study and illustrates the features which distinguish the approach from role play, simulation and experiential learning. When staff at Brunel University were faced with the problem of teaching Computer Integrated Manufacturing (CIM) to engineering students on thin sandwich type undergraduate degree programmes the writer suggested the use of an approach he would later describe as 'practice based learning' or 'real life simulation'. The fourth year course in CIM is designed as a double option for the complementary undergraduate courses, Brunel Manufacturing Engineering (BME) and Special Engineering Programmes (SEP). It is an extension of the Manufacturing Design and Practice course in years one to three of the BME course and of the Design strand on SEP, both of which restrict students' work to the use of individual machine tools and stand alone computing facilities. A wide range of teaching methods is used on the CIM course, including lectures by course staff, presentations by experts and, as the major element, a large group project involving all the students on the course, organised in a management matrix, coordinated by the students and supported by the staff acting as experts. The students also undertake assignment work alongside the technical tasks, to focus their thinking and to improve written communication skills. While the course described cannot replace more than a small proportion of the more conventional lecture, laboratory and tutorial teaching on an engineering programme, it provides a setting where students can experiment and learn about their own strengths and weaknesses in a realistic situation and in the context of teamwork. It also offers a space where they can make quite serious mistakes without direct consequences to their careers. The experience of seven years leads the author to believe that advanced manufacturing technologies and the associated management techniques should be taught in a project based environment with clear and real targets and realistic constraints, offering students challenges to which they can only rise through close and creative team work. The management of task execution must be left largely in the students' own hands. A high level of "consultant" type support is essential though, allied to an assessment scheme which promises and ensures fair treatment of the individual. The different parts of the thesis will be relevant to readers depending on their interest and background. Chapter 1 sets the scene and outlines the approach taken. Following this broad outline of the scope of the dissertation the author places Computer Integrated Manufacturing in a wider context in chapter 2, by providing an introduction to the underlying issues of computer integration and human factors. He puts forward a case for new approaches to the education and training of engineers and managers who will be working in Computer Integrated Manufacturing and Advanced Manufacturing Environments in general. Chapter 3 is devoted to the management of projects while chapter 4 is used to question the role of the engineer. Chapters 5 and 6 provide an introduction to theories of knowledge, teaching, learning and motivation. Chapters 7 and 8 are devoted to particular aspects of engineering education, while chapter 9 reviews the approach used at Brunel University. The topical issues of competence and its relevance to engineering education is discussed in chapter 10, leading into chapters 11 and 12 which deal with aspects of the CIM course. Chapters 13 and 14 are devoted to case-studies and particular tools. The key question of assessment of a practice oriented and team based course is addressed in chapter 15, followed by an evaluation of the CIM process and its application to engineering education of a full time nature which is included in chapters 17 and 18.Funding was obtained from The General Electric Company Prize 1993: Manufacturing Systems Engineering

    Is utility in the mind of the beholder? A review of ergonomics methods

    No full text
    This paper reviews the use of ergonomics methods in the context of usability of consumer products. A review of the literature indicated that there is upward of 60 methods available to the ergonomist. The results of the survey indicated that questionnaires, interviews and observation are the most frequently reported methods used. Ease of use of the methods was dependent upon type of method used, presence of software support and type of training received. Strong links were found between questionnaires and interviews as a combined approach, as well as with HTA and observation. However, a questionnaire survey of professional ergonomists found that none of the respondents had any documented evidence of the reliability and validity of the methods they were using. A study of training people to use ergonomics' methods indicated the different requirements of the approaches, in terms of training time, application time and subjective preferences. An important goal for future research is to establish the reliability and validity of ergonomics methods

    Reenergising professional creativity from a CHAT perspective: Seeing knowledge and history in practice

    Get PDF
    This is the author's accepted manuscript. The final published article is available from the link below. Copyright @ 2011 Regents of the University of California.This article offers a critical examination of aspects of a practice- and theory-developing intervention in the teacher education setting in England designed as a variation of Developmental Work Research. A positive case is argued for the distinctiveness of such cultural-historical activity theory [CHAT-] informed interventions and some points of contrast are drawn with the British tradition of educational action research. In describing the practice-developing intervention, the twin focus on seeing knowledge and history in human activity systems is advanced as two dimensions of CHAT's distinctive approach, with the goal of stimulating and studying the emergence of professional creativity. Creativity under this interpretation is defined as the perception and analysis of opportunities for learning within the social situation of development and the production of new conceptual tools and approaches to the social organisation of work. Professional creativity is advanced as a much needed capacity among teachers in industrial workplaces influenced by the techniques of New Public Management. Common ground between CHAT and action research approaches is seen in their optimistic and modernist commitments to progress, and CHAT-framed interventions, like action research approaches, are presented as part of an evolving intellectual project

    How adverse selection affects the health insurance market

    Get PDF
    Adverse selection can be defined as strategic behavior by the more informed partner in a contract against the interest of the less informed partner(s). In the health insurance field, this manifests itself through healthy people choosing managed care and less healthy people choosing more generous plans. Drawing on theoretical literature on the problem of adverse selection in the health insurance market, the author synthesizes concepts developed piecemeal over more than 20 years, using two examples and revisiting the classical contribution of Rothschild and Stiglitz. He highlights key insights, especially from the literature on"equilibrium refinements"and on the theory of"second best."The government can correct spontaneous market dynamics in the health insurance market by directly subsidizing insurance or through regulation; the two forms of intervention provide different results. Providing partial public insurance, even supplemented by the possibility of opting out, can lead to second-best equilibria. The same result holds as long as the government can subsidize contracts with higher-than-average premium-benefit ratios and can tax contracts with lower-than-average premium-benefit ratios. The author analyzes the following policy options relating to the public provision of insurance: a) Full public insurance. b) Partial public insurance with or without the possibility of acquiring supplementary insurance and with or without the possibility of opting out. In recent plans implemented in Germany and the Netherlands, where competition among several health funds and insurance companies was promoted, a public fund was created to discourage risk screening practices by providing the necessary compensation across riks groups. But only"objective"risk adjusters (such as age, gender, and region) were used to decide which contracts to subsidize. Those criteria alone cannot correct the effects of adverse selection. Regulation can exacerbate the problem of adverse selection and lead to chronic market instability, so certain steps must be taken to prevent risk screening and preserve competition for the market. The author considers the following three policy options for regulating the private insurance market: 1) A standard contract with full coverage. 2) Imposition of a minimum insurance requirement. 3) Imposition of premium rate restrictions.Health Economics&Finance,Environmental Economics&Policies,Insurance&Risk Mitigation,Insurance Law,Financial Intermediation

    Free Zone Incentives in MERCOSUR Countries and WTO Law

    Published source: Gabriel Gari, 'Free Zone Incentives in MERCOSUR Countries and WTO Law' (2011) 6 Global Trade and Customs Journal, Issue 5, pp. 223–244 ID: GTCJ2011031This article examines the consistency of the incentives offered by free zone regimes in Argentina, Brazil, Paraguay, and Uruguay with World Trade Organization (WTO) law. It suggests that some of the incentives offered to free zone users are inconsistent with the Agreement on Subsidies and Countervailing Measures (ASCM) because they constitute a ‘subsidy’ within the meaning of the ASCM, subject de iure or de facto to export performance, most notably, exemptions of direct taxes, exemptions of custom duties on the import of capital goods, exemptions of payment of social welfare charges, unqualified exemptions on payment of indirect taxes, and the possibility to supply goods or services to free zone users at promotional rates. By contrast, this article suggests that there are no significant inconsistencies between free zone incentives and the General Agreement on Trade in Services (GATS) but warns that the situation could change in the future if, as a result of multilateral negotiations, MERCOSUR countries opt for extending their GATS commitments to new sectors and modes of supply

    Disruption of the developmental programme of Trypanosoma brucei by genetic ablation of TbZFP1, a differentiation-enriched CCCH protein

    Get PDF
    The regulation of differentiation is particularly important in microbial eukaryotes that inhabit multiple environments. The parasite Trypanosoma brucei is an extreme example of this, requiring exquisite gene regulation during transmission from mammals to the tsetse fly vector. Unusually, trypanosomes rely almost exclusively on post-transcriptional mechanisms for regulated gene expression. Hence, RNA binding proteins are potentially of great significance in controlling stage-regulated processes. We have previously identified TbZFP1 as a trypanosome molecule transiently enriched during differentiation to tsetse midgut procyclic forms. This small protein (101 amino acids) contains the unusual CCCH zinc finger, an RNA binding motif. Here, we show that genetic ablation of TbZFP1 compromises repositioning of the mitochondrial genome, a specific event in the strictly regulated differentiation programme. Despite this, other events that occur both before and after this remain intact. Significantly, this phenotype correlates with the TbZFP1 expression profile during differentiation. This is the first genetic disruption of a developmental regulator in T. brucei. It demonstrates that programmed events in parasite development can be uncoupled at the molecular level. It also further supports the importance of CCCH proteins in key aspects of trypanosome cell function
