Recent research in CSCW shows that people become mobile in order to meet. Such meetings take place everywhere. Therefore, they are difficult to conduct using traditional meeting support. In this paper, we empirically examine mobility in face-to-face meetings. The objective is to characterise such encounters and suggest meeting support beyond the meeting(More)
This paper reports from a project, called NewsPilot, where we explore how context aware computing can be used to support mobile collaborators. An empirical study of journalists at a local radio station in Sweden has informed the design of a prototype system. The system is built using a personal digital assistant (PDA) fitted with a radio transceiver and(More)
The role of stressful life events in the onset of Graves' disease (toxic diffuse goitre) is controversial. However, the numerous early clinical reports that supported such an association were not adequately controlled and specificity of the diagnosis could be questioned. Later studies have not shown a causal relation, but these studies were small, did not(More)
STUDY OBJECTIVE To evaluate the clinical and biochemical features of patients with TSH (thyroid-stimulating hormone, thyrotropin)-secreting pituitary tumors; to measure the biologic activity in vitro of circulating TSH from selected patients before and after pituitary surgery. DESIGN Case series. SETTING Patients in an endocrinology unit. PATIENTS(More)
Proxy Lady is a mobile system for informal, opportunistic face-to-face communication, running on a PDA equipped with a radio transceiver. “Opportunistic communication” is anticipated by one party but it only occurs when the parties happen to meet each other. Proxy Lady supports such communication by providing notifications about possible “candidates for(More)
A sensitive gas chromatographic-mass spectrometric method enabled us to study intrathyroidal concentrations of methimazole in 20 euthyroid patients with Graves' disease on treatment with carbimazole and T4. There was no difference between patients receiving a final dose of carbimazole (10 mg), known to be totally bioactivated to methimazole (6.1 mg), 3-6 h(More)
The pharmacokinetics of methimazole following therapeutic doses were studied in healthy subjects, in thyrotoxic and hypothyroid patients before and after treatment to euthyroidism, and in patients with renal or hepatic insufficiency, using a highly sensitive gas chromatographic-mass spectrometric assay. Following intravenous administration of 10mg to(More)
The objective of this paper is to discuss how to enable the staff at an orderpackaging department to cope with a drastically increasing scale of operation. In order to do this we introduce the term scalability and based on co-ordination theory we formulate a case specific method for designing for an increasing scale of operation. We argue that it is the(More)
