We carried out a randomized controlled trial in Bogotá, the recipient of Colombia's highest number of internally displaced people (IDP), to assess whether the use of SMS to communicate eligibility to social benefits fosters the welfare of victimized internal refugees. Only a fraction of IDP are eligible to benefits. We inform eligibility via SMS to a random half of such households, and estimate...

T elimination of health disparities in the United States is a national priority and overriding goal for Healthy People 2010 (HP 2010). Surveillance of health indicators among minority populations is essential to eliminating disparities. Surveillance is critical for program planning, policy making, evaluating population-based strategies, and tracking progress toward national and state objectives.

Abstract: Some people automatically and involuntarily ”see” mental images of numbers in spatial arrays when they think of numbers. This phenomenon, called number forms, shares three key characteristics with the other types of synaesthesiae, within-individual consistency, between-individual variety, and mixture of regularity and randomness. An experiment was conducted to investigate whether ment...

Over the years a number of powerful people detectors have been proposed. While it is standard to test complete detectors on publicly available datasets, it is often unclear how the di erent components (e.g. features and classi ers) of the respective detectors compare. Therefore, this paper contributes a systematic comparison of the most prominent and successful people detectors. Based on this e...

In this paper we give a new approach to the concepts of glyph and character, applied to the study of the Unicode encoding. After a thorough discussion of these two concepts, we describe the other fundamental ingredients of the encoding: privileged glyphs, character descriptions, combining characters, and properties. In each case we try to show the importance of the given notion and at the same ...

Losses from the proton and antiproton beams of the Fermilab Tevatron have been shown to produce a halo which contribute to backgrounds to physics signals in the Collider Detector at Fermilab (CDF). To provide a measure of the beam halo and losses, we have installed arrays of scintillation counters on both sides of the CDF detector. We describe here the physical configuration of these counters, ...
