Diagnostic test evaluation of a nasal flow monitor for obstructive sleep apnea detection in sleep apnea research 总被引:1,自引:0,他引:1

In this diagnostic test evaluation of a nasal flow monitoring device for obstructive sleep apnea (OSA), 34 patients referred for polysomnography were studied at home for three consecutive nights with the monitor. The mean age of subjects (+/-SD) was 41.9+/-10.3 years, and their mean apnea-hypopnea index (AHI) was 31.5+/-27.2. The difference between the average AHI from three nights at home on the monitor and the polysomnogram (PSG) result was 1.8+/-17.1. The area under the receiver operating characteristic curve (AUC) for PSG AHI > or = 10 was .96. With a threshold AHI of 18 on the flow monitor, sensitivity was .92, specificity .86, positive predictive value .96, and negative predictive value .75. For detecting severe OSA (AHI > or = 30), the AUC was .85. With knowledge of appropriate thresholds and the pretest risk of OSA, the flow monitor can be used to detect or exclude OSA for sleep-related research, as well as to identify severe cases needing priority for further evaluation. 相似文献

Sound and complete axiomatizations are provided for a number of different logics involving modalities for the knowledge of multiple agents and operators for branching time, extending previous work of Halpern, van der Meyden and Vardi [to appear, SIAM Journal on Computing] for logics of knowledge and linear time. The paper considers the system constraints of synchrony, perfect recall and unique initial states, which give rise to interaction axioms. The language is based on the temporal logic CTL*, interpreted with respect to a version of the bundle semantics. 相似文献

Based on a model on spumed helpers’ reactions, a spurning scale for nurses was constructed with items to assess the extent
to which practicing nurses experience recurrent rejection of their help by patients and colleagues. Three approaches were
employed to examine the validity of the scale: the relationship of the spurning scores with job satisfaction and turnover
scores; the relationships of the spurning scores with burnout scores; and the relationships of the spurning scores with scores
indicative of stress arising from interactions with one's patients, colleagues, and supervisor. Practicing nurses in Hong
Kong (N = 212) who were enrolled in a refresher program of studies responded to a questionnaire containing the variables of
interest. The results offered promising evidence for the validity of the scale. 相似文献

Why would a consumer trust that his/her supplier would honor their agreement in illegal transactions? What mechanisms do consumers rely on to enhance the credibility of their agreements? In this article, these questions are examined in the light of illegal transactions of protected wildlife in China for consumption as a delicacy. Based on interviews with actors involved in this illegal market and open sources, this article shows that consumers rely on the supplier’s reputation to access protected wildlife, along with their reputation of having the culinary skills necessary to cook the wildlife in order to enhance the credibility of their agreements. 相似文献

This study examined (a) the extents to which primary school teachers experienced spurning of their help by peer teachers, (b) how spurned teachers reacted, and (c) how teachers’ self-esteem and importance attached to their teaching abilities influenced their reactions. Seven hundred eighty teachers in Guangzhou, China, responded to 3 waves of questionnaires assessing the variables under study. The results showed that the teachers experienced a moderate level of spurning, were seemingly threatened by the spurning, and reacted by disparaging the personal attributes of rejecting peers, with their self-esteem and importance attached to their teaching abilities exerting moderating effects. 相似文献

The purpose of this study is to address two issues. First, an effort is made to see if there are age differences in the prevalence of spiritual struggles. Second, tests are performed to see if age differences exist in the relationship between spiritual struggles and physical health. Data from a recent nationwide survey reveal that younger adults report that they encounter more spiritual struggles than either middle-aged or older adults. The findings further indicate that the negative relationship between spiritual struggles and health tends to become more pronounced at successively older ages. 相似文献

The Role of Risk in Making Decisions under Escalation Situations 总被引:2,自引:0,他引:2

Cet article décrit deux recherches portant sur la relation entre l'intensification de l'implication et trois variables liées au risque: la propension au risque, la perception du risque et l'attente du résultat. L'analyse des données montra (a) que l'intensification de l'implication était en relation négative avec la perception du risque et en relation positive avec la propension au risque et l'attente du résultat; (b) que la perception du risque médiatisait partiellement les effets de la propension au risque et que l'attente du résultat médiatisait les effets de la perception du risque. Ces observations sont dans l'ensemble cohérentes avec schéma théorique proposé par Sitkin et Pablo (1992). On discute des conséquences de cette recherche pour le comportement de prise de risque, l'intensification de l'implication et la pratique.
This paper reports on two studies examining the relationship between escalation of commitment and three risk-related variables—risk propensity, risk perception, and outcome expectancy. Results showed that (a) risk propensity and outcome expectancy were positively related to escalation of commitment, whereas risk perception was negatively related to escalation of commitment; (b) risk perception partially mediated the effects of risk propensity, and outcome expectancy mediated the effects of risk perception. These findings are generally consistent with the conceptual framework proposed by Sitkin and Pablo (1992 ). Implications for risk-taking behavior, escalation of commitment, and practice are discussed. 相似文献
