conclusions applying this information can be useful to policy makers and managers for planning and implementing special interventions to prevent and limit future accidental deaths. background traffic accidents are the main cause of deaths in developing countries. fatalities due to traffic accidents are assessed through a three-year time series forecast. objectives the aim of this study is to us...
Motivations for final position and for enclitic position: On the placing of the inflected verb in historical Basque Modern Basque (and historical Basque as a whole; generalized attestations start in the 16 century) is a XXIV-type language in Greenberg’s (1966) classification; that is, a non-rigid SOV language with Gen-N order and postpositions, but with N-Adj order. In the present work, I exami...
Plant phenological records are crucial for predicting plant responses to global warming. However, many historical records are either short or replete with data gaps, which pose limitations and may lead to erroneous conclusions about the direction and magnitude of change. In addition to uninterrupted monitoring, missing observations may be substituted via modeling, experimentation, or gradient a...
Social sustainability is one of the controversial issues which has far-reaching implications for the realms of architecture and urban design. In this respect, Joubareh Neighborhood in Isfahan, considered as the oldest historical location of the city, is of considerable importance. Despite the various values of this neighborhood, its historical texture has been deteriorating in recent years. Acc...
This report provides an overview of the exposure assessment process for an epidemiologic study that investigated mortality, with a special focus on lung cancer, associated with diesel exhaust (DE) exposure among miners. Details of several components are provided in four other reports. A major challenge for this study was the development of quantitative estimates of historical exposures to DE. T...
conclusions decreasing trend during recent six years reflects a partial success in leishmaniasis control, but update data regarding geographical cl distribution can guide our intervention effectively. results during our six years study, we observed a significant decreasing incidence trend. totally, 2863 cl cases were registered. risk of disease in men was 1.4 times more than women and in rural ...
BACKGROUND The California Tobacco Control Program (CTCP) has employed strategies to change social norms around smoking in order to decrease the prevalence of smoking and tobacco-related diseases. Research is scarce on CTCP's impact on overall smoking cessation in California. METHODS Tobacco Use Supplement to the Current Population Survey (TUS-CPS) data from 1992-1993 to 2006-2007 was used to ...
Ball and Mankiw (1995) use a static menu-cost model to explain the historical behaviour of the first and higher moments of commodity price changes in US producer prices. We show that when appropriately modified for a world of positive trend inflation and forward-looking behaviour by firms, the menu-cost model predicts a much weaker (possibly zero) correlation between the mean and the skewness o...
There are several organizations in Taiwan area which possess a lot of rare books, historical remains, artifacts and precious documents. However, the access of these collections seems unfortunately to be limited only to the minority of related researchers and scholars. This is against the overwhelming trend of information resources sharing. The most important thing is to distribute these valuabl...
The development of faster, simpler, inexpensive and more environmentally-friendly sample-preparation techniques is an important issue in chemical analysis. Recent research trends involve miniaturization of the traditional liquid-liquid-extraction principle by greatly reducing the acceptor-to-donor ratio. The current trend is towards simplification and miniaturization of sample preparation and d...
