  • Evidence-based medicine (EBM) has been famously characterized by David Sackett as the “conscientious, explicit, and judicious use of current best evidence in making decisions about individual care.” The central notion in EBM of the importance of integrating individual clinical expertise with the best available external evidence provides a helpful framework for providers navigating the uncertainty inherent in patient care.

  • The empirical relationship between capital controls and the financial development of credit and equity markets is examined. We extend the literature on this subject along a number of dimensions.Specifically, we (1) investigate a substantially broader set of proxy measures of financial development; (2) create and utilize a new index based on the IMF measures of exchange restrictions that incorporates a measure of the intensity of capital controls; and (3) extend the previous literature by systematically examining the implications of institutional (legal) factors.

  • A mutual fund is a type of investment fund. An investment fund is a collection of investments, such as stocks, bonds or other funds. Unlike most other types of investment funds, mutual funds are “open-ended,” which means as more people invest, the fund issues new units or shares. A mutual fund typically focuses on specific types of investments. For example, a fund may invest mainly in government bonds, stocks from large companies or stocks from certain countries. Some funds may invest in a mix of stocks and bonds, or other mutual funds....

  • From the methanolic extract of the roots of Ophiopogon confertifolius N. Tanaka (Convallariaceae) a new flavonoid named ophiofolius A (1) and two known compounds (2, 3) were isolated. Their structures were elucidated as 6,8-dimethyl-4’methoxy-5,7,3’,5’- tetrahydroxyflavanone (1), 6,8-dimethyl-3’,4’-dimethoxy-5,7,5’-trihydroxyflavanone (2), and 6- methoxy-5,7-dihydroxyflavanone (3) by the spectroscopic evidences (1D NMR, 2D NMR, ESI- MS).

  • For five months now all people who read at all have been reading about the horrible war that is devastating Europe and shedding the best blood of the people of five great nations. In fact, they have had no time to read anything else, and everything that is published about it is seized upon with great avidity. No wonder, then, that Mr. James M. Beck's book, The Evidence in the Case, published by G. P. Putnam's Sons, which has grown out of the article by him contributed to the New York Times Sunday Magazine, has been warmly welcomed both here and in England as a...

  • Vegetables and fruits are rich sources of antioxidants. There is good evidence that eating a diet that includes plenty of vegetables and fruits is healthy, and official U.S. Government policy urges people to eat more of these foods. Research has shown that people who eat more vegetables and fruits have lower risks of several diseases; however, it is not clear whether these results are related to the amount of antioxidants in vegetables and fruits, to other components of these foods, to other factors in people’s diets, or to other lifestyle choices....

  • We propose a novel algorithm for inducing semantic taxonomies. Previous algorithms for taxonomy induction have typically focused on independent classifiers for discovering new single relationships based on hand-constructed or automatically discovered textual patterns. By contrast, our algorithm flexibly incorporates evidence from multiple classifiers over heterogenous relationships to optimize the entire structure of the taxonomy, using knowledge of a word’s coordinate terms to help in determining its hypernyms, and vice versa. ...

  • Periodontal disease progression is episodic in nature on a tooth site level, but more recently, it has been realized that it is principally patient-based rather than site-based (Zia et al., 2011); the host related risk factors could be the key to better understand disease evolution. The available evidence shows that important risk factors for periodontal disease relate to poor oral hygiene, tobacco use, excessive alcohol consumption, stress, and diabetes mellitus (Laurina et al., 2009; Taylor & Borgnakke, 2008).

  • Whereas previously the emphasis had previously been on comparing original and translation, often with a view to establishing what had been ‘lost’ or ‘betrayed’ in the translation process, the new approach took a resolutely different line, seeking not to evaluate but to understand the shifts of emphasis that had taken place during the transfer of texts from one literary system into another.

  • Such studies show how writers' cultural backgrounds influence their organisation of writing; what they choose to use as evidence in supporting their main ideas; how they express their main ideas; and how they write in the foreign language (Benda, 1999). They also show how different rhetorical preferences are reflected in textual organisation in different languages (Grabe & Kaplan, 1989).

  • The birth and infancy of entrepreneurship was turned into a specific area of academic study and empirical research quite early. The field greatly evolved, and at the same time, a constant urge to deal with real problems existed, from firm creation to industrial growth, including firm strategy and economic policy. Economic, sociological, and managerial academics began to devise a detailed and interpretative framework for the study of entrepreneurship.

  • The very latest research is uncovering a stream of evidence revealing evolution in action - from the actual observation of a species splitting into two, to new fossil discoveries, to the deciphering of the evidence stored in our genome. Why Evolution is True weaves together the many threads of modern work in genetics, palaeontology,geology, molecular biology, anatomy, and development to demonstrate the 'indelible stamp' of the processes first proposed by Darwin. It is a crisp, lucid, and accessible statement that will leave no one with an open mind in any doubt about the truth of evolution....

  • While the discussion of abnormal profit generation in inefficient markets can apply to any number of asset classes that trade in private markets, most of these markets suffer from a lack of data availability. The real estate market is an exception in this respect, and therefore provides an excellent laboratory for constructing a systematic view of whether and how informed institutional-level investors can generate abnormal profits through active trading in a somewhat inefficient market.
