2004 Rockefeller New Media Foundation Proposal

Spectropia is an evening-length interactive media event. Projected on multiple screens, it is performed by two players with the participation of audience members at museums, festivals and public spaces. (A feature film and a home interaction version - combining WD and Internet delivery - will also be created.) Spectropia is a time travel drama set in the future and in NYC, 1931, after the stock market crash. It uses the metaphor of supernatural possession to explore new constructions of subjectivity and the anxieties brought on by consumer culture and emerging technologies. Unlike traditional movies, Spectropia is "performed" interactively using a unique mix of motion sensors, speech recognition and synthesis, and vocal triggers. Audience members, assisted by trained performer/tutors, can use physical cooperation to spontaneously unfold dialogue between onscreen characters; speak to the characters and have them respond; navigate through cinematic spaces; move a character's body; and alter and create the soundtrack. Spectropia has been supported by the Greenwall Foundation, Rockefeller Foundation MAP Fund, Langlois Foundation, LEF Foundation, NECA, NYFA, NEA, the ISA at Arizona State University, and The Banff Centre for the Arts

2005 Rockefeller New Media Foundation Proposal

Spectropia is a cinema scale interactive performance event, a "scratchable" movie performed by video DJs -- improvising performers who are playing a movie instrument. Projected on multiple screens and performed with the participation of audience members, it will be presented at museums, theaters, festivals and public spaces. A feature film and a home interaction version -- combining DVD and Internet delivery -- will also be created

A Disaggregation Methodology to Estimate Intake of Added Sugars and Free Sugars: An Illustration from the UK National Diet and Nutrition Survey

Various and inconsistent definitions for free and added sugars are used in the consideration and assessment of dietary intakes across public health, presenting challenges for nutritional surveillance, research, and policy. Furthermore, analytical methods to identify those sugars which are not naturally incorporated into the cellular structure of foods are lacking, thus free and added sugars are difficult to estimate in an efficient and accurate way. We aimed to establish a feasible and accurate method that can be applied flexibly to different definitions. Based on recipe disaggregation, our method involved five steps and showed good repeatability and validity. The resulting Free Sugars Database provided data for seven components of sugars; (1) table sugar; (2) other sugars; (3) honey; (4) fruit juice; (5) fruit puree; (6) dried fruit; and (7) stewed fruit, for ~9000 foods. Our approach facilitates a standardized and efficient assessment of added and free sugars, offering benefit and potential for nutrition research and surveillance, and for the food industry, for example to support sugar reduction and reformulation agendas

Portion size estimation in dietary assessment: a systematic review of existing tools, their strengths and limitations.

Context: Over or under estimation of portion size leads to measurement error during dietary assessment. Objective: To identify portion size estimation elements (PSEEs) and evaluate their relative efficacy in relation to dietary assessment; and assess the quality of studies validating PSEEs. Data selection and extraction: Electronic databases, internet sites and cross-references of published records were searched, generating 16,801 initial records, from which 334 records were reviewed and 542 PSEEs were identified comprising: 5% one- dimensional (e.g. food guides), 46% two- dimensional (e.g. photographic atlases) and 49% three- dimensional tools (e.g. household utensils). Out of 334 studies, 21 validated a PSEE (compared PSEE to actual food amounts) and 13 compared PSEEs against other PSEEs. Conclusion: Quality assessment showed that only a few validation studies were of high quality. According to the findings of validation and comparison studies, food image-based PSEEs were more accurate compared to food models and household utensils. Key factors to consider when selecting a PSEE include efficiency of the PSEE and its applicability to targeted settings and populations.B.A., EAR, P.P. and C.R. were supported by the Medical Research Council programme number U10596038

¿De burócratas a gerentes?: Las ciencias de la gestión aplicadas a la administración del Estado

Las lecturas que se compilan en este libro intentan hacer un aporte al desarrollo de la capacidad de gestión de las entidades públicas para conseguir sus objetivos, apoyándose en las ideas básicas provenientes de las ciencias de gestión, reagrupadas y readaptadas en el ámbito público bajo la denominación de New Public Management (NPM) o Nueva Gestión Pública. Esta publicación examina una amplia variedad de temas que va desde las aportaciones del marketing público a las nuevas técnicas en la mejora de la provisión de servicios, pasando por sugerentes e innovadoras ideas en la gestión del personal al servicio del Estado. La preocupación fundamental es identificar tanto la utilidad como las limitaciones de las técnicas y los conceptos provenientes de la gestión, sin pretender constituirse en una reflexión crítica de lo que ha sido su aplicación a la realidad de los diversos países de la región.
