Machinima interventions: innovative approaches to immersive virtual world curriculum integration
No full textThe educational value of Immersive Virtual Worlds (IVWs) seems to be in their social immersive qualities and as an accessible simulation technology. In contrast to these synchronous applications this paper discusses the use of educational machinima developed in IVW virtual film sets. It also introduces the concept of media intervention, proposing that digital media works best when simply developed for deployment within a blended curriculum to inform learning activity, and where the media are specifically designed to set challenges, seed ideas, or illustrate problems. Machinima, digital films created in IVWs, or digital games offer a rich mechanism for delivering such interventions. Scenes are storyboarded, constructed, shot and edited using techniques similar to professional film production, drawing upon a cast of virtual world avatars controlled through a human–computer interface, rather than showing real‐life actors. The approach enables academics or students to make films using screen capture software and desktop editing tools. In student‐generated production models the learning value may be found in the production process itself. This paper discusses six case studies and several themes from research on ideas for educational machinima including: access to production; creativity in teaching and learning; media intervention methodology; production models; reusability; visualisation and simulation
Risk factors for Escherichia coli O157 hide contamination of Scottish cattle
No full textThis thesis is an investigation into the risk factors for 'Escherichia coli' O157 hide contamination and hide cross-contamination of Scottish cattle at slaughter. In the slaughter processing of cattle, contaminated hides have been identified as one of the major sources of 'E. coli' O157 carcass contamination, which in turn is a significant food safety concern. In order to examine individual animal characteristics, farm management practices, and slaughterhouse features as potential risk factors, multivariable logistic regression analyses were applied to data collected in a study of 256 cattle from 34 farms sent for slaughter to twelve slaughterhouses in Scotland. Data sparsity issues were encountered, and therefore various methods of analyzing such data were explored. Modifiable risk factors for hide contamination and hide cross-contamination were identified, and could provide direction for the future development of 'E. coli' O157 hide contamination reduction strategies
O sistema medico Waimiri-Atroari: concepções e praticas
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas, Programa de Pós-Graduação em Antropologia, Florianópolis, 1995.Etnografia do grupo indígena Waimiri-Atroari nas questões ligadas à saúde: suas concepções e práticas. Análise da medicina nativa como sistema cultural, onde o processo da doença é muito mais uma experiência pessoal e coletiva do que simplesmente a caracterização dos sintomas físicos e diagnósticos clínico. Com intuito de compreender melhor o sistema médico do grupo, são explorados o complexo xamânico, mitologia e rituais. Os Waimiri-Atroari explicam a doença de acordo com seu sistema cosmológico, mas quando necessitam tratamento, para remoção dos sintomas, tendem a buscar os serviços oferecidos por um programa de assistência, o PWA (Programa Waikiri-Atroari, convênio FUNAI-ELETRONORTE). Fez-se uma breve avaliação sobre este programa
GIS and distributed hydrological models
No full textThe Water Information System (WIS), developed by the Institute of Hydrology as a hydrology-oriented GIS, was used as the spatial and time variable input, user interface and graphic output of the results for the hydrological modelling. A physically-based, quasi-distribution hydrological model (TOPMODEL) was linked with WIS as one of its application modules. Special techniques within the WIS framework allowing on-line data manipulation (data retrieving and updating) were developed. In particular, the database design was modified to handle time-series grids and the user interface was upgraded. Monte-Carlo simulation within a generalized likelihood uncertainty estimation (GLUE) framework, performed on a transputer system and initialized from WIS, was used for the calibration of TOPMODEL. -Author
