No full textObjectivesWe examined associations among race/ethnicity, socioeconomic factors, and driving status in a nationally representative sample of >26,000 U.S. high school seniors.MethodsWeighted data from the 2012 and 2013 Monitoring the Future surveys were combined and analyzed. We imputed missing values using fully conditional specification multiple imputation methods. Multivariate logistic regression modeling was conducted to explore associations among race/ethnicity, socioeconomic factors, and driving status, while accounting for selected student behaviors and location. Lastly, odds ratios were converted to prevalence ratios.Results23% of high school seniors did not drive during an average week; 14% of white students were nondrivers compared to 40% of black students. Multivariate analysis revealed that minority students were 1.8 to 2.5 times more likely to be nondrivers than their white counterparts, and students who had no earned income were 2.8 times more likely to be nondrivers than those earning an average of 65$36 a week. Driving status also varied considerably by student academic performance, number of parents in the household, parental education, census region, and urbanicity.ConclusionsOur findings suggest that resources\u2014both financial and time\u2014influence when or whether a teen will learn to drive. Many young people from minority or lower socioeconomic families who learn to drive may be doing so after their 18th birthday and therefore would not take advantage of the safety benefits provided by graduated driver licensing. Innovative approaches may be needed to improve safety for these young novice drivers.CC999999/Intramural CDC HHS/United State

No full textBrans-Dicke cosmological models for a spatially isotropic and homogeneous
universe are tested in terms of the validity of the Generalized Second Law of
Thermodynamics (GSL). The investigation is carried out in the Einstein frame.
It is found that the models are thermodynamically viable for negative values of
the Brans-Dicke parameter w and thus are quite consistent with the recent
accelerated expansion of the universe.Comment: 8 pages, to appear in EPJ

The feature vector being used to represent texts, consists of stem words as features and their weight values, which are obtained by applying 14 different term weighting schemes. The performances of these feature vectors for 3 different datasets in the author detection are tested with some classification methods such as Naive Bayes Multinominal (NBM), and Support Vector Machine (SVM), Decision Tree (C4.5), and Random Forrest (RF), and are compared with each other. As a result of that, the most successful classifier, which can predict the author of an article, is found as SVM classifier with 98.75% mean accuracy; the most successful term weighting scheme is found as ACTF.IDF.(ICF+1) with 91.54% general mean accuracy
Jordanian Nursing Work Environments, Intent to Stay, and Job Satisfaction
No full textPurposeThe purpose of this study was to examine associations among the nursing work environment, nurse job satisfaction, and intent to stay for nurses who practice in hospitals in Jordan.DesignA quantitative descriptive crossâ sectional survey design was used.MethodsData were collected through survey questionnaires distributed to 650 registered nurses (RNs) who worked in three hospitals in Jordan. The selfâ report questionnaire consisted of three instruments and demographic questions. The instruments were the Practice Environment Scale of the Nursing Work Index (PESâ NWI), the McCain Intent to Stay scale, and Quinn and Shepard’s (1974) Global Job Satisfaction survey. Descriptive statistics were calculated for discrete measures of demographic characteristics of the study participants. Multivariate linear regression models were used to explore relationships among the nursing work environment, job satisfaction, and intent to stay, adjusting for unit type.FindingsThere was a positive association between nursesâ job satisfaction and the nursing work environment (t = 6.42, p < .001). For each oneâ unit increase in the total score of the PESâ NWI, nursesâ average job satisfaction increased by 1.3 points, controlling for other factors. Overall, nurses employed in public hospitals were more satisfied than those working in teaching hospitals. The nursing work environment was positively associated with nursesâ intent to stay (t = 4.83, p < .001). The Intent to Stay score increased by 3.6 points for every oneâ unit increase in the total PESâ NWI score on average. The highest Intent to Stay scores were reported by nurses from public hospitals.ConclusionsThe work environment was positively associated with nursesâ intent to stay and job satisfaction. More attention should be paid to create positive work environments to increase job satisfaction for nurses and increase their intent to stay.Clinical RelevanceHospital and nurse managers and healthcare policymakers urgently need to create satisfactory work environments supporting nursing practice in order to increase nursesâ job satisfaction and intent to stay.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/135980/1/jnu12265_am.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/135980/2/jnu12265.pd
Communication With Physicians as a Mediator in the Relationship Between the Nursing Work Environment and Select Nurse Outcomes in Jordan
No full textPurposeTo test whether communication mediated relationships among nursesâ work environments and nurse outcomes of job satisfaction and intent to stay.DesignThis study used a crossâ sectional, quantitative survey design to query 650 nurses who worked in three hospitals in Jordan.MethodsWe used Arabic versions of valid, reliable instruments measuring the nursing work environment, nurse perceptions of communication with physicians, intent to stay, and job satisfaction. Mediation analysis was used to test hypotheses.FindingsA total of 582 questionnaires were returned (89.5% response rate). Nurse perceptions of communication with physicians mediated the relationship between the nursing work environment and job satisfaction in medical, surgical, and critical care units. Nurse perceptions of communication with physicians mediated the relationship between the nursing work environment and intent to stay in all but maternity and â otherâ units.ConclusionsDepending on the nurse outcome, communication was a significant mediator for various unit types. These results may be related to the type of work that is done in each unit and the influence of patient care. Communication is one of many mechanisms that can specify how a positive nursing work environment can contribute to nursesâ job satisfaction and intent to stay.Clinical RelevanceA potential solution to the nursing shortage in Jordan emerges by identifying communication with physicians as a mediator in the relationship between the work environment and selected nurse outcomes.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/146637/1/jnu12417_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/146637/2/jnu12417.pd
