    This research aimed to investigate mobile 3D scanning technologies to improve the 3D data capture methods and workflow efficiency for Canvasman Ltd a SME company based in Otley near Leeds, UK. At this phase in the Collaborative Venture Fund (CVF) project the researchers have provided results to the company and a detailed scoping case based technical report. The report includes a product market survey of handheld 3D scanners, product evaluation matrix, 3D software review, and user testing and analysis experiments into each selected 3D portable scanning hardware and software from a range of providers including: Faro, Artec, and the Structure Sensor for IPad. The presentation, focused on communicating the key phases of the CVF project with the company and other industry partners. And outlined some of the exciting interdisciplinary applications of 3D scanning technologies for colleagues and practitioners across disciplines, not only in art, design, architecture, and engineering, to improve efficiency of data capture, visualisation, archive, design and development of any object, or interior and exterior spaces within the human centred and built environment. The session in which the research was presented in is titled, ADA in materials and visual culture, and it addressed the role of materials in the production of new knowledge in art and design practice and theory. Historically art and design has always involved collaborative exchanges: between artists, historians, theorists, consultants, designers, technicians, engineers and policy makers. Today new technologies and innovations - capturing form with data is just one example – offer opportunities for artists and designers to engage in novel trans-disciplinary research relationships. This poses the question how to initiate, develop and sustain research collaborations beyond the conventions of our traditional disciplinary boundaries

    Matching Evaluation Approaches to Expectations

    In the nonprofit sector, evaluation is a word that gets used a lot. Different kinds of data gathering approaches with different purposes sometimes get lumped together under the general heading of evaluation. This can lead to miscommunication and unrealistic expectations. To try to clear things up a bit, we have created this resource

    Making Evaluation Work in the Nonprofit Sector: A Call for Systemic Change

    This position paper is a call for systemic changes that will create an ecosystem within which it is straightforward, efficient, and rewarding for nonprofits and funders to invest in evaluation work. It is also intended to further critical conversations to build a nonprofit sector that is more responsive, accountable, and focused on the best ways to support the communities in which they work

    Hidden on the ward : the abuse of children in hospitals

    Get PDF
    While there have been a small number of high profile cases of the abuse of children by hospital staff, there has been relatively little attention paid to the child protection issues for children staying in hospitals. Drawing on a conceptual framework from work on institutional abuse, we identify three types of abuse: physical and sexual abuse; programme abuse; and system abuse. Physical and sexual abuse can be perpetrated by medical professionals and hospital workers, it can be perpetrated by other children, or it can be perpetrated by the child's own parent(s). Research evidence from the United States suggests that the rate of abuse in hospitals is higher than in the family home. Programme abuse occurs when treatment and care falls below normally accepted standards. Recently, a tragic case of programme abuse concerned the unacceptably high death rate of babies undergoing heart surgery at Bristol Royal Infirmary. System abuse is the most difficult to define but concerns the way in which child health services fail to meet the needs of children. Recent reports have highlighted inadequate services for children and young people, lack of priority given to children's services, and geographical inequalities in the provision of services. Three crucial aspects in safeguarding children from abuse are highlighted: listening to children; the selection support and training of staff; and external systems of inspection, monitoring and standards. The recent government agenda which has placed quality at the centre of NHS service developments are discussed. Only by addressing the abuse of children in hospital openly and honestly will effective child protection be possible

    Exploring the Issues: An Evaluation Literature Review

    Get PDF
    Finding ways to make evaluation more meaningful and more useful has been a key theme in the evaluation literature since the discipline began, and there is no shortage of discussion around improving evaluation among nonprofit practitioners. The topic has been a highlight at ONN's annual conference in recent years.However, much of the discussion around improving evaluation focuses on methodology, tools, and indicators.There has been less attention paid to who is asking and determining the questions of evaluation, such as who evaluation is for and what is its purpose. Consequently, the purpose of this background paper is to review the literature on evaluation use with a particular focus on systemic factors. In other words, we are interested in looking at the relationship between evaluation practice and the overall structure and function of the nonprofit sector in Ontario.We're interested in the policies and regulations that guide us, the roles played by various actors, theassumptions we make, the language we use, and the ways in which resources move through the sector. We're examining the purposes that evaluation serves, both overt and implicit. We want to learn more about the factors that make evaluations really useful, the issues that can get in the way of evaluations being useful, and ideas for improvement. Ultimately, our goal in this paper is to generate a broad vision to inform our project's final outcomes

    An experimental study to test a 3D laser Scanner for body measurement and 3D virtual garment design in Fashion education

    Artists, scientists, anthropometrists and tailors have accurately measured the human body with traditional tools, such as tape measures, callipers and accumulated visceral experience for centuries. Due to the progressive acceleration in the quality of 3D graphics technology and computer processing power, many product industries that traditionally use 3D software as a 3D design and prototyping tool, are also successfully measuring, customizing and re-engineering the products they design and manufacture through the integrated use of 3D Laser scanning technology. In the changing world of Fashion, 3D graphics technology has at last emerged from the shadows of academic research projects and hit the high streets. 3D body measurement surveys, using mobile 3D laser scanners, have mapped the true shape and body sizes of the UK and USA populations. Virtual fit and 3D visualisation technology has expanded out from the Internet, into the physical world, and is now available for shoppers to visualise made to measure garments. The acceptance of three-dimensional body-scanning and 3D digital design tools into our everyday experiences can be seen as a significant move toward encouraging and developing new, innovative learning and teaching methods in Art & Design education. This paper describes an experimental study into the application of 3D laser scanner technology for use in learning and teaching of undergraduate and postgraduate fashion and textiles design; clothing manufacture, fashion marketing, merchandising and promotion. The study focuses on testing the 3D scanning equipment with a student sample group. The use of the sample group attempts to simulate a range of body shapes, categorised by the traditional standard size chart specification method, currently used to design new fashion collections for high street clothing retail and UK fashion education. The methods applied for evaluation and testing of the 3D laser scanner for body measurement are described, and the results of the initial user experiences are discussed. The study seeks to establish the overall efficiency of 3D scanning technology and investigates the potential value for integration of the 3D Laser scanner with 3D clothing design and construction software. Conclusions provide recommendations on the potential effectiveness of connecting the results of the 3D body measurement study to the fashion curriculu

    Evolution of the probability distribution function of galaxies in redshift-space

    We present a new analytic calculation for the redshift-space evolution of the 1-point galaxy Probability Distribution Function (PDF). The nonlinear evolution of the matter density field is treated by second-order Eulerian perturbation theory and transformed to the galaxy density field via a second-order local biasing scheme. We then transform the galaxy density field to redshift space, again to second order. Our method uses an exact statistical treatment based on the Chapman-Kolmogorov equation to propagate the probability distribution of the initial mass field to the final redshifted galaxy density field. We derive the moment generating function of the PDF and use it to find a new, closed-form expression for the skewness of the redshifted galaxy distribution. We show that our formalism is general enough to allow a non-deterministic (or stochastic) biasing prescription. We demonstrate the dependence of the redshift space PDF on cosmological and biasing parameters. Our results are compared with existing models for the PDF in redshift space and with the results of biased N-body simulations. We find that our PDF accurately models the redshift space evolution and the nonlinear biasing.Comment: 15 pages, 7 figures, submitted to MNRA
