Introduction: The impact history of the solar system remains controversial. Early investigation of lunar samples, returned by Apollo astronauts, led to the 'Late Heavy Bombardment' (LHB) concept [1,2] which hypothesized a sharp increase in bolide flux centered around ~3.9 Ga. Evidence for this cataclysm was first derived from whole-rock U-Pb and Rb-Sr ages [2] but subsequently more on 40 Ar-39 ...

Introduction: The aim of this abstract is to acquaint the reader with the major geochemical and geochronological properties of lunar rocks formed or affected by impact events, and thus how these rocks constrain lunar bombardment history, with particular emphasis on constraints upon the proposed Lunar Cataclysm or Late Heavy Bombardment [1]. To this end, the focus is on clast-poor impact melt ro...

The study was undertaken to evaluate (a) the reliability of pedometer data and reactivity of children to wearing a pedometer, (b) the effectiveness of a missing data replacement procedure, and (c) the validity of the Leisure Time Exercise Questionnaire (LTEQ). Six days of pedometer data were collected from 299 middle-school children, followed by administration of the LTEQ. Six days of pedometer...

Background The killing of women by intimate partners (also known as intimate female homicide or intimate femicide) is the most extreme form and consequence of violence against women. Globally, gender differences are found in homicide patterns. Men are at greater risk of being killed than women and this is mainly done by other men. Women, on the other hand, are primarily killed by the opposite g...

— The paper shows that the current view of globalization as an automatic and benign force is flawed: it focuses on only one, positive, face of globalization while entirely neglecting the malignant one. The two key historical episodes that are adduced by the supporters of the ‘‘globalization as it is’’ (the Halcyon days of the 1870–1913, and the record of the last two decades of development) are...

A firm understanding of fatherhood in the present requires a deep appreciation of fatherhood in the past. To demonstrate what this proposition means, and to illustrate how complex fatherhood can be, I provide an overview of the social reconstruction of fatherhood in America between 1800 and 1960. It was during these 160 years that we see significant transformations in U.S. society and in the so...

Last November, I spent several days in the skyscrapers of Canary Wharf, in banks’ headquarters in the City and in the pale wood and glass of a hedge fund’s St James’s office trying to understand the credit crisis that had erupted over the previous four months. I became intrigued by an oddity that I came to think of as the end-of-theworld trade. The trade is the purchase of insurance against wha...
