The measurement of patient satisfaction

Abstract: Many applied health service researchers launch into patient satisfaction surveys without realizing the complexity of the task. This paper identifies the difficulties involved in executing patient satisfaction surveys. The recent revival of interest in 'satisfaction' and disagreements over the meaningfulness of a unitary concept itself are outlined, and the various perspectives and definitions of the components of satisfaction are explored. The difficulties of developing a comprehensive conceptual model are considered, and the issues involved in designing patient satisfaction surveys--and the disasters that occur when these issues are ignored--are then set out. The potential cost-effectiveness of qualitative techniques is discussed, and the paper concludes by discussing how health care management systems could more effectively absorb the findings of patient satisfaction surveys.

Movement and force produced by a single myosin head

Abstract: MUSCLE contraction is driven by the cyclical interaction of myosin with actin, coupled to the breakdown of ATP. Studies of the interaction of filamentous myosin1 and of a double-headed proteolytic fragment, heavy meromyosin (HMM)2,3, with actin have demonstrated discrete mechanical events, arising from stochastic interaction of single myosin molecules with actin. Here we show, using an optical-tweezers transducer2,4, that a single myosin subfragment-1 (S1), which is a single myosin head, can act as an independent generator of force and movement. Our analysis accounts for the broad distribution of displacement amplitudes observed, and indicates that the underlying movement (working stroke) produced by a single acto-Sl interaction is ~4 nm, considerably shorter than previous estimates1–3,5 but consistent with structural data6. We measure the average force generated by S1 or HMM to be at least 1.7 pN under isometric conditions.

The collective construction of work group moods.

Abstract: This research examines mood as a collective property of work groups We argue that work group members experience group moods when they can detect and display mood information through observable beh
