SETTING OUR RESEARCH AGENDAS: INSTITUTIONAL ECOLOGY, INFORMING SCIENCES, OR MANAGEMENT FASHION THEORY?

A new reflexive discourse is emerging in the IS research community concerning how we, as academic scholars in the information systems field, set and pursue our research agendas. How should we choose our research topics, how should we conduct our research, and how should we communicate our research results? This panel will present and debate the merits of three distinct perspectives concerning the setting of our research agendas in information systems. There will be three short rounds of presentations by the three panelists: Richard Baskerville, Grandon Gill and Neil Ramiller. Following these presentations, Michael Myers (panel chair) will briefly summarize the discussion so far and give his own views with respect to the merits of the three arguments. After suggesting some key points for debate, he will then facilitate what promises to be an interesting and lively discussion with the audience

The High Speed Balancing Game: How Software Companies Cope with Internet Speed

This paper compares and contrasts the practices in developing application software for the Internet in 2000 and 2002. We identify key organizational and technical factors that facilitated or impeded implementation of Internet applications. The identification is done through a grounded theory analysis of data collected from ten companies. A comparison of the 2000 and 2002 data shows how major factors, such as market environment and lack of experience emerged to change the software process and the attitude towar

What Every Business Student Needs to Know About Information Systems

Whether Information Systems should or should not be part of the core business school curriculum is a recurring discussion in many universities. In this article, a task force of 40 prominent information systems scholars address the issue. They conclude that information systems is absolutely an essential body of knowledge for business school students to acquire as well as a key element of the business school\u27s long-run strategic positioning within the university. Originally prepared in response to draft accreditation guidelines prepared by AACSB International, the article includes a compilation of the concepts that the authors believe to be the core information systems knowledge that all business school students should be familiar with

Length of carotid stenosis predicts peri-procedural stroke or death and restenosis in patients randomized to endovascular treatment or endarterectomy.

BACKGROUND: The anatomy of carotid stenosis may influence the outcome of endovascular treatment or carotid endarterectomy. Whether anatomy favors one treatment over the other in terms of safety or efficacy has not been investigated in randomized trials. METHODS: In 414 patients with mostly symptomatic carotid stenosis randomized to endovascular treatment (angioplasty or stenting; n = 213) or carotid endarterectomy (n = 211) in the Carotid and Vertebral Artery Transluminal Angioplasty Study (CAVATAS), the degree and length of stenosis and plaque surface irregularity were assessed on baseline intraarterial angiography. Outcome measures were stroke or death occurring between randomization and 30 days after treatment, and ipsilateral stroke and restenosis ≥50% during follow-up. RESULTS: Carotid stenosis longer than 0.65 times the common carotid artery diameter was associated with increased risk of peri-procedural stroke or death after both endovascular treatment [odds ratio 2.79 (1.17-6.65), P = 0.02] and carotid endarterectomy [2.43 (1.03-5.73), P = 0.04], and with increased long-term risk of restenosis in endovascular treatment [hazard ratio 1.68 (1.12-2.53), P = 0.01]. The excess in restenosis after endovascular treatment compared with carotid endarterectomy was significantly greater in patients with long stenosis than with short stenosis at baseline (interaction P = 0.003). Results remained significant after multivariate adjustment. No associations were found for degree of stenosis and plaque surface. CONCLUSIONS: Increasing stenosis length is an independent risk factor for peri-procedural stroke or death in endovascular treatment and carotid endarterectomy, without favoring one treatment over the other. However, the excess restenosis rate after endovascular treatment compared with carotid endarterectomy increases with longer stenosis at baseline. Stenosis length merits further investigation in carotid revascularisation trials
