BACKGROUND The 2014 Ebola epidemic in West Africa has attracted public interest worldwide, leading to millions of Ebola-related Internet searches being performed during the period of the epidemic. This study aimed to evaluate and interpret Google search queries for terms related to the Ebola outbreak both at the global level and in all countries where primary cases of Ebola occurred. The study ...

purpose: to investigate the proportion and time trend of second-eye senile cataract surgery (secs) in a high-turnover academic center in iran. methods: in this cross-sectional study, samples were selected among all records of senile cataract surgery based on the international statistical classification of diseases and related health problems, 10th revision (icd-10) during four consecutive years...

This survey highlights the recent advances in algorithms for numerical linear algebra that have come from the technique of linear sketching, whereby given a matrix, one first compressed it to a much smaller matrix by multiplying it by a (usually) random matrix with certain properties. Much of the expensive computation can then be performed on the smaller matrix, thereby accelerating the solutio...

Purpose – The purpose of this paper is to encompass the assessment of the effectiveness of the digital library and the value of multidisciplinary databases in terms of user preferences and use frequency by academic ranking. Design/methodology/approach – This paper compares the results of two survey questionnaires carried out in 2002 and 2005. It examines the level of awareness by academic staff...

There are noted disparities by ethnicity, race, age, gender, and socioeconomic status in the reported use of and access to cancer information. Missing from this list of variables that predict these disparities are specific geographic locales, such as Appalachia, a region recognized as a medically underserved, “special population”. Through a secondary analysis of NCI’s 2003 HINTS dataset, we are...

The development of a prophylactic vaccine to prevent infection with oncogenic subtypes of human papillomavirus (HPV) is an important step in reducing cervical cancer incidence and mortality. However, national data indicate that only 37% of 13- to 17-year-old females have initiated the vaccine series. Prior studies have examined demographic, medical history, and psychosocial variables associated...

In visual surveillance face detection can be an important cue for initializing tracking algorithms. Recent work in psychophics hints at the importance of the local context of a face for robust detection, such as head contours and torso. This paper describes a detector that actively utilizes the idea of local context. The promise is to gain robustness that goes beyond the capabilities of traditi...

disability weight ð1Þ YLL 1⁄4 Number of deaths life expectancy at the age of death ð2Þ DALY 1⁄4 YLD þ YLL ð3Þ The philosophical and methodological aspects of the DALY calculation have been described (and debated) in great detail (Murray 1994; Murray and Acharya 1997; for critiques, see, amongst others, Anand and Hanson 1997), and are summarized in the accompanying Hints and Kinks paper (Devlees...

The collaboration of faculty and library in Problem Based Learning (PBL) has led to an abundance of studies in the medical and health sciences. This article reports on the emerging roles of librarians in studies on PBL implementation during the past 10 years. The initial analysis revealed studies which focussed on the effects of PBL on library usage. However the trend has since evolved to studi...

Hydrologic regime is highly dependent on climate change, as hydrologic cycle components are directly influenced by climatic conditions. This paper analyzes the impacts of climate change on the hydrologic regime of the Atrak River basin in the northeast of Iran. It drains to the Caspian Sea. The data collected at 11 hydrometeorological stations were examined to detect trends in hydroclimatologic...
