DECISION CRITERIA IN THE ADOPTION OF EDI

Electronic data interchange, or EDI, has been discussed in literature as a technology that can provide a strategic advantage to its adopters, like other interorganizational information systems. However, its actual rate of adoption is nowhere near the predictions. Authors are now reconsidering their assessment of EDI\u27s advantages and its role in organizations\u27 strategies. However, using works found in critical mass theory, and through results gathered with the survey, case study and computer-supported interviews, this paper shows that organizations are acting strategically when deciding to not adopt EDI. They base their decisions on what their business partners are doing with respect to EDI, and on whether the actual and potential businesses they represent justify the investment required in EDI. The implications of the results for the study of innovation diffusion are discussed

Comment des adolescents vivent le suicide d’un jeune ami : une étude exploratoire

Cette étude qualitative a été menée dans le but de mieux comprendre l'expérience que vivent des adolescents endeuillés du suicide d'un camarade. Des entrevues ont été effectuées avec cinq adolescents amis du suicidé. La proposition principale qui a émergé de l'analyse des données par théorisation ancrée s'énonce comme suit : pour ces adolescents, le suicide de leur camarade est un geste difficile à comprendre qui les entraîne dans une quête de sens. Lorsque ces jeunes apprennent le suicide de leur ami, s'amorce une tourmente caractérisée par une panoplie d'émotions. S'ensuit une série de questions auxquelles ces adolescents essaient de répondre par diverses explications. Malgré une période d'apaisement, le questionnement persiste sur les véritables raisons qui auraient poussé leur camarade à se suicider. La discussion permet d'établir des liens avec d'autres études sur le deuil.How adolecents experience the suicide of a friend: an exploratory study The objective of this qualitative study was undertaken for a better understanding of the experiences of grieving adolescents following a peer suicide. Interviews were carried out with five adolescents whose friends committed suicide. The principal finding emerging from the data analysis, based on grounded theory, witnesses the following: for these adolescents, peer suicide is a difficult gesture to understand leading them to a quest of self-inquiry. When these adolescents learned of the suicide, they experienced turmoil characterised by a panoply of emotions. This state was followed by a series of questions to which the adolescents sought various responses. Despite a decline in these turbulent emotions, a process of questioning continued to discern the true reasons behind the suicide of their peer. Throughout the presentation of results, links are established with other studies.Como adolescentes viven el suicidio de un amigo joven: un estudio exploratorio Este estudio cualitativo fue realizado con el objetivo de mejorar la comprensión de la experiencia que viven los adolescentes ensombrecidos por el suicidio de un compañero.

The PALFA Survey: Going to great depths to find radio pulsars

The on-going PALFA survey is searching the Galactic plane (|b| < 5 deg., 32 < l < 77 deg. and 168 < l < 214 deg.) for radio pulsars at 1.4 GHz using ALFA, the 7-beam receiver installed at the Arecibo Observatory. By the end of August 2012, the PALFA survey has discovered 100 pulsars, including 17 millisecond pulsars (P < 30 ms). Many of these discoveries are among the pulsars with the largest DM/P ratios, proving that the PALFA survey is capable of probing the Galactic plane for millisecond pulsars to a much greater depth than any previous survey. This is due to the survey's high sensitivity, relatively high observing frequency, and its high time and frequency resolution. Recently the rate of discoveries has increased, due to a new more sensitive spectrometer, two updated complementary search pipelines, the development of online collaborative tools, and access to new computing resources. Looking forward, focus has shifted to the application of artificial intelligence systems to identify pulsar-like candidates, and the development of an improved full-resolution pipeline incorporating more sophisticated radio interference rejection. The new pipeline will be used in a complete second analysis of data already taken, and will be applied to future survey observations. An overview of recent developments, and highlights of exciting discoveries will be presented.Comment: Proceedings of IAUS 291 "Neutron Stars and Pulsars: Challenges and Opportunities after 80 years", J. van Leeuwen (ed.); 6 pages, 4 figure

La création de nos propres institutions : une voie à emprunter

Cet article relate notre expérience de gestion féministe qui est en constante évolution depuis 14 ans. Nous y discutons, tout particulièrement, de la question de la création d’institutions féministes. Les concepts et les critères de féminisation que nous présentons sont le fruit d’un processus de théorisation des pratiques de La coopérative Convergence. Cet exercice, que nous avons nommé « Peau neuve », nous a permis de réfléchir sur nos pratiques, de raffiner notre analyse et de positionner ..
