This paper concerns the effects of macroeconomic announcements on the covariance structure of US government bond returns for six different maturities; the study shows that the conditional variances, covariances, and correlation coefficients are significantly greater on announcement days. On non-announcement days, the correlation coefficients are relatively(More)
OBJECTIVE To conduct an expert-led process for identifying research priorities in adolescent sexual and reproductive health in low- and middle-income countries. METHODS The authors modified the priority-setting method of the Child Health and Nutrition Research Initiative (CHNRI) to obtain input from nearly 300 researchers, health programme managers and(More)

There is a growing evidence base for preconception care--the provision of biomedical, behavioral and social interventions to women and couples before conception occurs. Firstly, there is evidence that health problems, problem behaviours and individual and environmental risks contribute to poor maternal and child health outcomes. Secondly, there are(More)
The paper investigates volatility spillover from US and aggregate European asset markets into European national asset markets. A main contribution is that bond and equity volatilities are analyzed simultaneously. A new model belonging to the " volatility-spillover " family is suggested: The conditional variance of e.g. the unexpected German stock return is(More)
Like the stock market, the human capital market consists of a wide range of assets, i.e. educations. Each young individual chooses the educational asset that matches his preferred combination of risk and return in terms of future income. A unique register-based data set with exact information on type and level of education enables us to focus on the shared(More)
This paper applies a life-course perspective to the problem of early pregnancy and pregnancy-related mortality and morbidity in adolescents in developing countries. It describes the contribution that two categories of "pregnancy-focused" programmes make-firstly, the provision of effective care and support in the antenatal, childbirth, and postnatal periods(More)
On 17 November 2011, the United Nations General Assembly adopted a resolution (A/RES/66/170) designating 11 October as the first International Day of the Girl Child choosing ending child marriages as the theme of the day. Child marriage is a fundamental human rights violation and impacts all aspects of a girl's life. These marriages deny a girl of her(More)
Severe simultaneous recessions are defined to occur when at least half of the countries under investigation (Australia, Canada, Germany, Japan, United Kingdom, and United States) are in recession simultaneously. I pose two new research questions that extend upon stylized facts for US recessions. One, are the occurrences of simultaneous recessions(More)
Heteroduplex analysis of mitochondrial DNA (mtDNA) from evolutionary closely related mammals (rat vs. mouse, man vs. monkey) are analyzed and compared to heteroduplex analysis of mt-DNA from more distantly related mammals (rat vs. man, rat vs. monkey, mouse vs. man, mouse vs. monkey and man vs. cow). Each analysis is transformed into a heteroduplex map and(More)
