Past research provides instructive yet incomplete answers as to how incumbent firms can address competing concerns as they embrace digital innovation. This research offers only partial explanations of why different concerns emerge, how they manifest, and how firms can manage them. In response, we present a longitudinal case study of Volvo Car's connected car initiative. Combining extant literature with insights from the case, we argue that incumbent firms face four competing concerns-capability (existing versus requisite), focus (product versus process), collaboration (internal versus external), and governance (control versus flexibility)-and that these concerns are systemically interrelated. Firms must manage these concerns cohesively by continuously balancing new opportunities and established practices.

One patient of 5 ended up with a permanent stoma after low anterior resection of the rectum for cancer, and half of the patients with a permanent stoma had previous symptomatic anastomotic leakage.

Even though the literature on competence in organizations recognizes the need to align organization level core competence with individual level job competence, it does not consider the role of information technology in managing competence across the macro and micro levels. To address this shortcoming, we embarked on an action research study that develops and tests design principles for competence management systems. This research develops an integrative model of competence that not only outlines the interaction between organizational and individual level competence and the role of technology in this process, but also incorporates a typology of competence (competence-in-stock, competence-in-use, and competence-in-the-making). Six Swedish organizations participated in our research project, which took 30 months and consisted of two action research cycles involving numerous data collection strategies and interventions such as prototypes. In addition to developing a set of design principles and considering their implications for both research and practice, this article includes a selfassessment of the study by evaluating it according to the criteria for canonical action research.

It is possible to treat rAAA with EVAR. Hypotensive patients can, at least initially, be operated under local anesthesia to stabilize blood pressure utilizing a percutaneously inserted occlusion balloon. There was a trend in our study for reduced mortality and morbidity with EVAR, but further studies are required to conclude whether EVAR significantly increases survival and reduces complications.
