Global Night-Time Lights for Observing Human Activity

We present a concept for a small satellite mission to make systematic, global observations of night-time lights with spatial resolution suitable for discerning the extent, type and density of human settlements. The observations will also allow better understanding of fine scale fossil fuel CO2 emission distribution. The NASA Earth Science Decadal Survey recommends more focus on direct observations of human influence on the Earth system. The most dramatic and compelling observations of human presence on the Earth are the night light observations taken by the Defence Meteorological System Program (DMSP) Operational Linescan System (OLS). Beyond delineating the footprint of human presence, night light data, when assembled and evaluated with complementary data sets, can determine the fine scale spatial distribution of global fossil fuel CO2 emissions. Understanding fossil fuel carbon emissions is critical to understanding the entire carbon cycle, and especially the carbon exchange between terrestrial and oceanic systems

An exploratory study of Muslim adolescents' views on sexuality: Implications for sex education and prevention

<p>Abstract</p> <p>Background</p> <p>This paper describes the results of an exploratory qualitative study on Muslim adolescents' views on sexuality in the Netherlands.</p> <p>Methods</p> <p>Data were gathered from an Internet forum on which 44 Muslim and 33 non-Muslim adolescents discussed sexuality as it relates to Islam. These discussions were subsequently analyzed for content using Nvivo 2.0.</p> <p>Results</p> <p>Our analysis revealed several issues that are relevant for the design of future sex education programs targeting Muslim youth. Apart from some expected outcomes regarding, for example, taboos on sexuality, sex outside marriage, abortion, homosexuality and conservative gender roles, our analyses showed that in cases of disputes 1) discussions were polarized, 2) opponents used the same Qur'anic passages to support their views, and 3) the authority of an Imam was questioned when his interpretation of Qur'anic passages was not in line with the views of participants.</p> <p>Conclusions</p> <p>Our findings show that current approaches to sex education among Muslim youth are likely to be unsuccessful given the rigidity of sexual norms in Muslim society. In addition, we also identified new barriers to sex education among Muslim youth (e.g. lack of respect for an Imam who opposes a youth's views on sexuality).</p

Liver disease and its effect on haemostasis during liver transplantation

In a prospective study involving 25 consecutive adult orthotopic liver transplantation (OLT) patients, of whom 23 had cirrhosis, we have related pretrans‐plantation recipient parameters to blood loss during transplantation. In phase I (explantation of diseased liver) blood loss was 0.1–7.2 1, in phase 3 (following restoration of the portal blood flow after implantation) 0.1–39.7 1, and total blood loss was 1.6–47.2, median 9.21. Five patients (20%) died from causes directly related to defective haemostasis during the operation. Pretransplantation cholinesterase, antithrombin III and albumin correlated most strongly with blood loss in phase 1; a history of ascites, antithrombin III and cholinesterase levels correlated with blood loss in phase 3, and a history of ascites, urinary sodium and antithrombin III with total blood loss. Cholestasis did not influence blood loss. Portal hypertension per se presumably played only a restricted role. A pretransplant 24‐h urinary sodium excretion of 10 mmol or less and a serum sodium of 132 mmol/1 or less were highly predictive of blood loss exceeding 10 1 during OLT. Urinary sodium determination under test conditions and serum sodium measurement should already be part of the assessment of potential OLT candidates by the referring hospital

Prairie

Prairie is a library of scripts for Unity that enables non-programmers to create interactive historical experiences. FEATURES Prairie provides a robust interaction system which allows game designers to quickly and easily add tactile interactivity to their scenes. Prairie provides a streamlined method to add historical context directly into the game environment. The annotation system allows historians to add annotation footnotes to the objects and locations within the scene. Together with Twine, Prairie provides an easy method to write a non-linear story, and then have players experience that situation firsthand in a historical game

Images of Earth and Space II

This videotape tours the Solar System and outer space using scientific visualizations from Goddard Space Flight Center, Jet Propulsion Laboratory, and the HPCC Earth and Space Sciences Project. At the Sun, simulations investigate processes that create magnetic field and release energetic particles. Earth science begins with the Pacific Ocean, studying the 1997-98 El Nino and Cyclone Susan. Crossing the globe, visualizations trace North Americas East Coast and ocean currents in the North Atlantic Ocean. The lights of the worlds cities then show human impact. Next, two models probe nearby-space phenomena, fluid behavior in microgravity conditions and an asteroid collision. A jaunt to Mars explores the mountains and trenches of its dry, rocky exterior. The video concludes at a binary neutron star system, where two city-sized objects with the Suns mass merge in a titanic explosion.
