It often seems that the health care numbers and vital statistics in Africa are as hazy as the sun on the horizon. Medical statistics, for example, can come with staggering margins of error. The World Health Organization notes in “2011 World Health Statistics” that “there are considerable uncertainty ranges for many countries due to limitations in data availability, quality and timeliness. Uncer...

In this work, we demonstrate the power of providing a common set of operating system services to Grid Archi-tectures, including high-performance I/O, communication, resource management and process management. AGrid[1] enables the sharing, selection, and aggregation of a wide variety of geographically distributed resourcesincluding supercomputers, storage systems, data sources, and s...

This paper develops an asymptotic theory for test statistics in linear panel models that are robust to heteroskedasticity, autocorrelation and/or spatial correlation. Two classes of standard errors are analyzed. Both are based on nonparametric heteroskedasticity autocorrelation (HAC) covariance matrix estimators. The …rst class is based on averages of HAC estimates across individuals in the cro...

Aggression can have a critical impact on the functioning of societies. Some aspects of aggression have received considerable attention, such as links between parenting behavior and offspring aggression in humans. Although acknowledged as being important to the understanding of human aggression, animal aggression has been relatively unstudied. Recent mammalian animal research is emerging that ad...

We provide the impact on asset prices of search-and-bargaining frictions in over-the-counter markets. Under natural conditions, prices are lower and illiquidity discounts higher when counterparties are harder to find, when sellers have less bargaining power, when the fraction of qualified owners is smaller, or when risk aversion, volatility, or hedging demand are larger. If agents face risk lim...

Opioids are potent analgesics, but the sites of their action and cellular mechanisms are not fully understood. The central nucleus of the amygdala (CeA) is important for opioid analgesia through the projection to the periaquaductal gray (PAG). In this study, we examined the effects of opioid receptor stimulation on inhibitory and excitatory synaptic inputs to PAG-projecting CeA neurons retrogra...

INTEGRATION und KOOPERATION sind die Oberziele für ein besseres und effizienteres Management im ländlichen Bereich mit Einbeziehung von Umweltund Riskmanagement. Dies ist weltweit zu fordern! Dazu ist aber eine ICT Infrastruktur für das gesamte Segment notwendig welche unter Berücksichtigung der gegebenen Strukturen Basisdaten und Basistechnologie für die am Sektor beteiligten Strukturen – egal...
