The Unit Of Analysis In Is Theory: The Case For Activity, Helen Hasan, Sumayya Banna Jan 2010

The Unit Of Analysis In Is Theory: The Case For Activity, Helen Hasan, Sumayya Banna

In the field of IS, researchers use and adapt existing theories to make sense of their data. They also build new theory from their research findings. The way theory is used, adapted or created usually assumes a certain unit of analysis, which could be the artefact, the system, the organisation, the user, the developer, the team or something else. In this paper we propose that ‘activity’ should also be considered as a suitable unit of analysis for theory in IS since the purpose of any information systems is to facilitate activities of use. To support this proposition, we describe tenets …

A new age of significance and opportunity for Information Systems (IS) is upon us driven by current developments in the use of digital artifacts. In this paper we endeavor to make sense of contemporary IS, as well as possible future directions of IS, by bringing together the notions of complexity and activity within two theoretical frameworks, namely the Cynefin framework and contemporary uses of Activity Theory. We describe activity as a holistic unit of analysis within the Complicated and Complex Domains of the Cynefin framework. This will enable us to make sense of tool-mediated IS activities in those Domains. Our …

The aim of this study was to verify the relation between body mass index (BMI) and sitting time in a sample of 4,091 Azorean men. BMI was calculated from self-reported weight and height. Total physical activity (PA) time and total sitting time were assessed with the IPAQ (short version). Linear Regression analysis showed that total sitting time (hours/day) was positively associated with BMI (B = 0.078; p < 0.001) after adjustments for age, meal frequency, alcohol and tobacco consumptions, island of residence, education level and total PA time. Although the cross sectional design precludes us from establishing causality, our findings emphasize the importance of reducing sedentary behavior to decrease the risk of obesity.


Citrate Synthase Activity Does Not Account For Age-Related Differences In Maximum Aerobic Performance In House Sparrows (Passer Domesticus), William A. Buttemer, C Bech, Mark A. Chappell Jan 2010

We measured basal (BMR) and peak metabolic rates (PMR) in juvenile and adult House Sparrows. Juvenile birds had significantly higher BMR, but lower PMR than adult birds, despite having statistically indistinguishable body masses. We then evaluated the relation between PMR and masses of central and peripheral organs and found that pectoral muscle mass best correlated with PMR in both groups, accounting for about 35% of the variation in PMR. Because citrate synthase (CS) has such major importance in affecting the first committed step in the tricarboxylic acid cycle, we characterized CS activity levels In extracted muscles to see if this …
