What matters most to patients? Participative provider care and staff courtesy

Although there is growing recognition of the importance of having satisfied patients, we know little about what aspects of care matter most to patients. The sources of patient satisfaction and how care delivery can influence them need more empirical study. The objective of this study was to identify which aspects of a patient’s experience of care are most important to patient satisfaction, and how dimensions of care relate to clinic size, economic performance, and employee job satisfaction. To explore our question, longitudinal survey data were obtained on patients and employees over two years (1996 and 1997). Relationships between patient satisfaction and the two most critical care experience dimensions, clinic size, economic performance, and job satisfaction were examined. As of result, six major dimensions of patients\u27 experience of care were identified: 1) participative provider care, 2) staff courtesy, 3) self-reported sickness, 4) waiting, 5) staff follow-up, and 6) medical explanations. The first two factors, participative provider care and staff courtesy, account for more than 37% of the total variance in patients’ experience of care. Patient satisfaction is negatively and significantly correlated with clinic size but not correlated with job satisfaction, physician productivity, or clinic profitability. The article concludes suggesting that the personal relationships of a patient with his/her doctor and clinic staff are the strongest predictors of patient satisfaction. Patient satisfaction was found to be unrelated to the employee job satisfaction, physician productivity, and clinic economic performance

Optimal Tradeoff Between Exposed and Hidden Nodes in Large Wireless Networks

Wireless networks equipped with the CSMA protocol are subject to collisions due to interference. For a given interference range we investigate the tradeoff between collisions (hidden nodes) and unused capacity (exposed nodes). We show that the sensing range that maximizes throughput critically depends on the activation rate of nodes. For infinite line networks, we prove the existence of a threshold: When the activation rate is below this threshold the optimal sensing range is small (to maximize spatial reuse). When the activation rate is above the threshold the optimal sensing range is just large enough to preclude all collisions. Simulations suggest that this threshold policy extends to more complex linear and non-linear topologies

The Dirichlet Obstruction in AdS/CFT

The obstruction for a perturbative reconstruction of the five-dimensional bulk metric starting from the four-dimensional metric at the boundary,that is, the Dirichlet problem, is computed in dimensions $6\leq d\leq 10$ and some comments are made on its general structure and, in particular, on its relationship with the conformal anomaly, which we compute in dimension $d=8$.Comment: 13 pages, references added (this paper supersedes hep-th/0206140, "A Note on the Bach Tensor in AdS/CFT", which has been withdrawn

Aggregated dynamic demand equations for specialistic-outpatient medical care:(Estimated from a time-series of cross-sections)

In this paper a dynamic model is presented which describes the development of the demand for specialistic medical care in The Netherlands, during the period 1960-1972. The "regionally correlated, time-wise auto-regressive" model is consistently estimated from a time-series of cross-sections, using a modified Aitken estimator. The dependent variables are the number of publicly insured patients referred from general care to specialistic care, and the amount of care consumed per patient referred. As independent variables we took demographic factors, the supply of different levels of medical care and the insurance system. The estimation results show a.o. important substitution possibilities between general and specialistic care, and a significant influence of supply and supply-related variables on the demand for specialistic care.</p

Are tearful individuals perceived as less competent? Probably not

What are the social signals of emotional tears? This question has fascinated scholars ever since Darwin. Studies have suggested several interpersonal effects of emotional tears. A recent study by Van de Ven, Meijs, and Vingerhoets (2017) presented evidence in three studies that tearful individuals are perceived as warmer, but also less competent than their non-tearful counterparts. However, the competence effect was relatively small, and a recent replication failed to find such an effect in two different populations while the warmth effect was replicated (Zickfeld &amp; Schubert, 2018). This questions the generalizability of the effect of tears on perceived competence. To test whether individuals expressing emotional tears are really perceived as less competent and what boundary conditions such an effect might have, we specified a decision tree of three different studies in which we test differences between the original reference study and the replication. We replicated previous findings of the perceived (in)competence in Study 1 (n = 531) but observed a considerably smaller non-significant effect when proceeding to Study 2 (n = 471), which increased the number of stimuli. The earlier and now repeated replication failure can therefore likely be attributed to an increased variation in stimulus material. We conclude that there is not enough evidence to argue that one social outcome of tears signals a relative lack of competence as the effect seems to depend on the specific stimuli used.info:eu-repo/semantics/acceptedVersio

Slipping friction of an optically and magnetically manipulated microsphere rolling at a glass-water interface

The motion of submerged magnetic microspheres rolling at a glass-water interface has been studied using magnetic rotation and optical tweezers combined with bright-field microscopy particle tracking techniques. Individual microspheres of varying surface roughness were magnetically rotated both in and out of an optical trap to induce rolling, along either plain glass cover slides or glass cover slides functionalized with polyethylene glycol. It has been observed that the manipulated microspheres exhibited nonlinear dynamic rolling-while-slipping motion characterized by two motional regimes: At low rotational frequencies, the speed of microspheres free-rolling along the surface increased proportionately with magnetic rotation rate; however, a further increase in the rotation frequency beyond a certain threshold revealed a sharp transition to a motion in which the microspheres slipped with respect to the external magnetic field resulting in decreased rolling speeds. The effects of surface-microsphere interactions on the position of this threshold frequency are posed and investigated. Similar experiments with microspheres rolling while slipping in an optical trap showed congruent results.Comment: submitted to Journal of Applied Physics, 11 figure
