Remote Predictive Mapping 1. Remote Predictive Mapping (RPM): A Strategy for Geological Mapping of Canadaâs North
Remote Predictive Mapping (RPM) techniques are being developed and refined by the Geological Survey of Canada for mapping Canadaâs North. Remote Predictive Mapping should be considered an integral part of the geological mapping process designed to involve compilation, and re-compilation of data derived from existing geological maps, aerial photographs, satellite imagery, and airborne geophysical data. Predictive geological maps may be iteratively revised and upgraded to publishable geological maps by integrating remotely sensed data with newly acquired field and laboratory data, as RPM techniques are progressively tested and insight evolves. A predictive map, produced without collection of new, field-based data, may also serve as a first-order geologic map in areas where field-based studies cannot be accomplished due to expense of field access or remoteness. As a welcome consequence of adopting RPM into the normal work flow of any mapping or exploration project, there will, by necessity, be greater participation and integration of expertise of field geologists, geophysicists, Geographic Information System (GIS) and remote sensing specialists. Significantly, RPM also encourages geoscience organizations to make full use of all available geoscience data.
This paper outlines a strategy for RPM and provides processing and interpretation examples based on a variety of geoscience data and interpretation techniques to be employed for geologic mapping.
SOMMAIRE
La Commission gĂ©ologique du Canada dĂ©veloppe et raffine des techniques de tĂ©lĂ©cartographique prĂ©dictive (TCP) pour cartographier du Nord canadien. La tĂ©lĂ©cartographie prĂ©dictive doit ĂȘtre perçue comme une composante intĂ©grĂ©e dâun processus de cartographie gĂ©ologique de compilation et de recompilation de donnĂ©es extraites de cartes gĂ©ologiques, de photographies aĂ©riennes, dâimageries satellitaires, et de gĂ©ophysiques aĂ©roportĂ©es existantes. Les cartes gĂ©ologiques prĂ©dictives peu-vent ainsi ĂȘtre rĂ©visĂ©es, mises Ă jour et publiĂ©es selon une approche itĂ©rative intĂ©grant les donnĂ©es de tĂ©lĂ©dĂ©tection avec les donnĂ©es de terrain et de laboratoire nouvellement acquises, au grĂ© de lâĂ©volution et du raffinement des techniques de TCP. Dans les cas de rĂ©gions trop Ă©loignĂ©es, ou parce que les coĂ»ts dâĂ©tablissement de cartes gĂ©ologiques de base rĂ©guliĂšres seraient prohibitifs, la TCP peut aussi ĂȘtre utilisĂ©e pour produire une carte gĂ©ologique de base. DâentrĂ©e de jeu, on rĂ©alise que lâadoption de la TCP dans la routine de production normale de tout projet de cartographie ou dâexploration permettra, en soi, une meilleure prise en compte et une meilleure intĂ©gration des savoirs-faires des gĂ©ologues de terrain, des gĂ©ophysiciens et des spĂ©cialistes de la tĂ©lĂ©dĂ©tection et des systĂšmes dâinformation gĂ©ographique (SIG). Par sa nature mĂȘme, la TCP permet aux organisations gĂ©oscientifiques de faire plein usage de toutes les donnĂ©es gĂ©oscientifiques dont elles disposent.
Le prĂ©sent article dĂ©finit une stratĂ©gie de TCP et dĂ©crit des exemples de traitement et dâinterprĂ©tation dâune variĂ©tĂ© de donnĂ©es gĂ©oscientifiques et de techniques dâinterprĂ©tation utilisables pour la production de cartes gĂ©ologiques
Production analysis applied to work improvement
This Note provides and introduction to the research being carried out in the Department of Civil Engineering at Loughborough University and funded by the Science and Engineering Research Council (SERC) into Work Study applied to construction work. The emphasis is directed towards ascertaining site efficiency factors and the methods of determining operation times. In subsequent notes the measuring techniques will be explained in detail and examples of typical data for us in estimating and cost control described
ïżŒRecidivism Risk Assessment for Aboriginal Males: A Brief Review of the Scientific Literature
No level of violent recidivism is acceptable to Correctional Service of Canada staff or the Canadian public. Among other tools, CSC staff use counselling, supervision, education, and treatment programs to ensure the safe community reintegration of eligible offenders. The core method of determining risk for recidivism is an actuarially-based risk assessment instrument. The general process of contemporary risk assessment is outlined in this paper revealing a number of efficient and effective measures suitable for all male offender populations. Theory and research are reviewed showing that established risk prediction factors such as age, criminal history, anti-social peers, anti-social attitudes, and substance abuse predict criminal recidivism for all offenders regardless of cultural, racial, or geographic heritage. The majority of these validated risk assessment instruments have moderate predictive power for all male offenders. Seven of these instruments are individually reviewed with regard to their use with Aboriginal groups. This paper concludes with recommendations for further research on risk assessment among cultural groups

Direct Minimization Generating Electronic States with Proper Occupation Numbers
We carry out the direct minimization of the energy functional proposed by
Mauri, Galli and Car to derive the correct self-consistent ground state with
fractional occupation numbers for a system degenerating at the Fermi level. As
a consequence, this approach enables us to determine the electronic structure
of metallic systems to a high degree of accuracy without the aid of level
broadening of the Fermi-distribution function. The efficiency of the method is
illustrated by calculating the ground-state energy of C and Si
molecules and the W(110) surface to which a tungsten adatom is adsorbed.Comment: 4 pages, 4 figure
Ethical issues and GenomEUtwin
The post-genomic era is witnessing a proliferation of large-scale and population based genetic and genomic research projects. Many countries have or are establishing research biobanks and, as with GenomEUtwin, there is great interest in building multinational projects that link genotypic and phenotypic information from different centers. Clearly, the conduct of these projects raises multiple ethical issues, and the knowledge generated will continually recast the ethical, legal and social implications (ELSI) of such research. Maximising the scientific profit from this work while minimizing the risks to the participants requires full integration of ethics components into the structure and functioning of these projects. GenomEUtwin is organized around five intellectual cores, including an Ethics Core which operates across the entire project. This paper describes the role of the Ethics Core and presents an overview of the guidelines on which the principles followed in GenomEUtwin are based. We outline the major ethical concerns of our project and highlight complexities arising from diverse national legislations. Finally, the role of empirically based ethics research is discussed for understanding the ethical, legal, social and economic implications of human genetics and genomics research
