background traumatic brain injury (tbi) is an important public health problem throughout the world. objectives the aim of this study was to assess repeated glasgow coma scale (gcs) scores in predicting the severity of tbi and patients’ survival. patients and methods in this longitudinal study used a total sample of 239 patients, all of whom were hospitalized with traumatic brain injuries. subje...

Ss judged "ratios of distances" and "differences of distances" between pairs of U.S. cities. Results fit the theory that Ss used two comparison processes as instructed. A ratio scale of distances between cities was constructed from the 2 rank orders. From this scale, an interval scale of the city locations on an east-west continuum was derived. This scale agrees with the subtractive model fit t...

BACKGROUND Cognitive impairments are common in Parkinson's disease (PD). Despite its clinical importance, the development of dementia is still difficult to predict. In this study, we investigated the possible associations between non-motor symptoms and the risk of developing dementia within a 2-year observation period in PD. METHODS A total of 80 patients with PD participated in this study. N...

BACKGROUND There is still only limited understanding of whether and why interventions to facilitate the implementation of guidelines for improving primary care are successful. It is therefore important to look inside the 'black box' of the intervention, to ascertain which elements work well or less well. AIM To assess the associations of key elements of a nationwide multifaceted prevention pr...

OBJECTIVE To determine whether functional status near the time of discharge from acute care hospitalization is associated with acute care readmission. PATIENTS AND METHODS Retrospective cohort study of 9405 consecutive patients admitted from an acute care hospital to an inpatient rehabilitation facility between July 1, 2006 and December 31, 2012. Patients' functional status at admission to th...

BACKGROUND What currently appears to be irreversible axonal loss in normal appearing white matter, measured by proton magnetic resonance spectroscopy is of great interest in the study of Multiple Sclerosis. Our aim is to determine the axonal damage in normal appearing white matter measured by magnetic resonance spectroscopy and to correlate this with the functional disability measured by Multip...

The objective was to investigate associations ofperceived stress with sleep duration and quality among 430 police officers. Perceived stress was assessed using the perceived stress scale. Sleep duration and quality were assessed using the Pittsburg sleep quality index questionnaire. Mean hours of sleep were determined across quartiles of perceived stress using ANOVA/ANCOVA. Logistic regression ...

In this study, Jatropha curcas oil was used as feedstock for biodiesel production by alkali-catalyzed methanolysis. To establish the optimum conditions for biodiesel production, effects of certain factors were investigated, these factors are oil-to-methanol molar ratios (1:4 1:8), KOH catalyst concentrations (0.5 1.5% w/w oil), reaction temperatures (50 70oC), and reaction times (55 90minutes)....

Early statistical methods focused on pre-data probability statements (i.e., data as random variables) such as P values; these are not really inferences nor are P values evidential. Statistical science clung to these principles throughout much of the 20th century as a wide variety of methods were developed for special cases. Looking back, it is clear that the underlying paradigm (i.e., testing a...
