Beacon; Horizon

Horizon is a narrative clock made out of images accessed in realtime from webcams found in every time zone around the world. The result is a constantly updating array of images that read like a series of movie storyboards, but also as an idiosynratic global electronic sundial. BEACON continuously relays live web searches as they are being made around the world presenting them back in series and at regular intervals as an endless concrete poetry.

Horizon & BEACON

Timecode was a group show at Dundee Contemporary Arts in 2009. Others Artists included where Douglas Gordon, Tatsuo Miyajima, On Kawara, Ceal Floyer, Christian Stock. Thomson and Craighead where commissioned to make an new installation,Horizon and accompanying limited edition print for the exhibition. Also included in the exhibition was a Beacon in the form of a railway flapsign. Horizon is a narrative clock made out of images accessed in realtime from webcams found in every time zone around the world. The result is a constantly updating array of images that read like a series of movie storyboards, but also as an idiosynratic global electronic sundial. BEACON as a unique mechanical railway flap sign built by Solari of Udine in Italy. As with the online and projected version of BEACON, this mechanical half-flap sign continuously relays live web searches as they are being made around the world presenting them back in series and at regular intervals as an endless concrete poetry.

Expanding the research horizon in higher education : master's students' perceptions of research assistantships

This study explores how effectively current research assistantships impart research methods, skills, and attitudes; and how well those experiences prepare the next generation of researchers to meet the evolving needs of an ever-expanding, knowledge- based economy and society. Through personal interviews, 7 graduate student research assistants expressed their perceptions regarding their research assistantships. The open- ended interview questions emphasized (a) what research knowledge and skills the graduate students acquired; (b) what other lessons they took away from the experience; and (c) how the research assistantships influenced their graduate studies and future academic plans. After participants were interviewed, the data were transcribed, memberchecked, and then analyzed using a grounded theory research design. The findings show that research assistantships are valuable educational venues that can not only promote research learning but also benefit research assistants' master's studies and stimulate reflection regarding their future educational and research plans. Although data are limited to the responses of 7 students, findings can contribute to the enhancement of research assistantship opportunities as a means of developing skilled future researchers that in tum will benefit Canada as an emerging leader in research and development. The study is meant to serve as an informative source for (a) experienced researchers who have worked with research assistants; (b) researchers who are planning to hire research assistants; and (c) experienced and novice research assistants. Further, the study has the potential to inform future research training initiatives as well as related policies and practices.

Infinite-Horizon Choice Functions

We analyze infinite-horizon choice functions within the setting of a simple linear technology. Time consistency and efficiency are characterized by stationary consumption and inheritance functions, as well as a transversality condition. In addition, we consider the equity axioms Suppes-Sen, Pigou-Dalton, and resource monotonicity. We show that Suppes-Sen and Pigou-Dalton imply that the consumption and inheritance functions are monotone with respect to time—thus justifying sustainability—while resource monotonicity implies that the consumption and inheritance functions are monotone with respect to the resource. Examples illustrate the characterization results.

L'horizon et la colonne, réflexions sur la relation intérieur-extérieur chez Le Corbusier

Ce mémoire explore la question du rapport intérieur-extérieur chez Le Corbusier se questionnant sur la façon dont la notion d’interpénétration spatiale, postulat majeur de l’architecture moderne, est présente dans son discours. À travers l’étude des croquis, photos et notes de son Voyage d’Orient, ainsi que de certains principes architecturaux énoncés dans ses ouvrages théoriques emblématiques des années 1920, nous allons saisir chez Le Corbusier une pensée qui transcende l’idée d’objet architectural et révèle un intérêt spécial porté au site et à la dialectique horizontale-verticale. Certains dispositifs ou éléments architecturaux, tels que la colonnade et la colonne, vont se révéler aux yeux du maître, lorsqu’ils se trouvent dans des espaces de transition entre l’intérieur et l’extérieur, porteurs d’une fonction médiatrice entre l’homme et son milieu, et ce sera par le biais d’un outil de mesure : l’angle droit. Cette recherche entend contribuer à la compréhension de la pensée architecturale de Le Corbusier, notamment en ce qui concerne la relation architecture-paysage en tant qu’expérience phénoménale.

La réduction des méfaits en contexte carcéral québécois et canadien : tour d'horizon des pratiques connues.

Bon nombre de consommateurs de substances psychoactives se retrouvent dans les institutions carcérales québécoises et canadiennes. Or, leur consommation ne s'arrête pas nécessairement avec l'incarcération. Les taux de prévalence de consommation en prison et en pénitencier en témoignent. Aux prises avec les méfaits qui y sont associés (propagation des maladies virales, intoxication, etc.), les autorités pénitentiaires et de santé publique sont priées de trouver une réponse appropriée. En communauté, les pratiques de réduction des méfaits ont déjà démontré des résultats positifs au-delà de l'amélioration des comportements à risque. Toutefois, est-il possible d'adopter, dans un contexte carcéral, une approche visant à atténuer les méfaits associés à la consommation de drogue plutôt que de prôner l'abstinence totale de toute drogue? Cet article tente une réponse à cette question en se basant sur un bref survol international des mesures adoptées en prison, mais plus spécifiquement en analysant celles entérinées à l'intérieur des murs québécois et canadiens. Il en ressort qu'une concertation entre les différentes instances correctionnelles, judiciaires et de santé publique s'avère essentielle dans l'adoption de mesures de réduction des méfaits et que doivent s'arrimer les soins prépost et carcéraux. / Many consumers of psychoactive substances are found in Quebec's and Canada's prisons. However, their consumptions do not necessarily stop with the imprisonment. The prevalence rates of consumption in penitentiaries institutions testifies it. The penitentiaries and the public health authorities are requested to find a suitable answer to the harms associated with the drug consumption (propagation of the viral diseases, intoxications, etc). In community, the harm reduction practices already showed positive results beyond the improvement of the consumers' risk behaviors. However, in the context of the incarceration, is it possible to adopt an approach aiming harm reduction associated with drugs consumption rather than the abstinence with any drug? While being based on a short international abstract of the measures adopted in prison, this article tries an answer specifically by analyzing those ratified inside the Québécois' and the Canadians' prisons. This study reveals that coordinates dialogues between the various correctional, legal and of public health authorities are essentials in the adoption of effective harms reduction measures. And those measures must be organized in a continuum with the pre-post and prison care.

Institutional Repositories: New Horizon of Science & Technology Knowledge Transactions

Today higher education system and R&D in science & Technology has undergone tremendous changes from the traditional class room learning system and scholarly communication. Huge volume of Academic output and scientific communications are coming in electronic format. Knowledge management is a key challenge in the current century .Due to the advancement of ICT, Open access movement, Scholarly communications, Institutional repositories, ontology, semantic web, web 2.0 etc has revolutionized knowledge transactions and knowledge management in the field of science & technology. Today higher education has moved into a stage where competitive advantage is gained not just through access of infonnation but more importantly from new Knowledge creations.This paper examines the role of institutional repository in knowledge transactions in current scenario of Higher education.

Coordinating Inventory Control and Pricing Strategies with Random Demand and Fixed Ordering Cost: The Finite Horizon Case

We analyze a finite horizon, single product, periodic review model in which pricing and production/inventory decisions are made simultaneously. Demands in different periods are random variables that are independent of each other and their distributions depend on the product price. Pricing and ordering decisions are made at the beginning of each period and all shortages are backlogged. Ordering cost includes both a fixed cost and a variable cost proportional to the amount ordered. The objective is to find an inventory policy and a pricing strategy maximizing expected profit over the finite horizon. We show that when the demand model is additive, the profit-to-go functions are k-concave and hence an (s,S,p) policy is optimal. In such a policy, the period inventory is managed based on the classical (s,S) policy and price is determined based on the inventory position at the beginning of each period. For more general demand functions, i.e., multiplicative plus additive functions, we demonstrate that the profit-to-go function is not necessarily k-concave and an (s,S,p) policy is not necessarily optimal. We introduce a new concept, the symmetric k-concave functions and apply it to provide a characterization of the optimal policy.

Coordinating Inventory Control and Pricing Strategies with Random Demand and Fixed Ordering Cost: the Infinite Horizon Case

We analyze an infinite horizon, single product, periodic review model in which pricing and production/inventory decisions are made simultaneously. Demands in different periods are identically distributed random variables that are independent of each other and their distributions depend on the product price. Pricing and ordering decisions are made at the beginning of each period and all shortages are backlogged. Ordering cost includes both a fixed cost and a variable cost proportional to the amount ordered. The objective is to maximize expected discounted, or expected average profit over the infinite planning horizon. We show that a stationary (s,S,p) policy is optimal for both the discounted and average profit models with general demand functions. In such a policy, the period inventory is managed based on the classical (s,S) policy and price is determined based on the inventory position at the beginning of each period.

Stable receding horizon control based on recurrent networks

The last decade has seen the re-emergence of artificial neural networks as an alternative to traditional modelling techniques for the control of nonlinear systems. Numerous control schemes have been proposed and have been shown to work in simulations. However, very few analyses have been made of the working of these networks. The authors show that a receding horizon control strategy based on a class of recurrent networks can stabilise nonlinear systems.
