Is there any relationship between child labour, crime rates and country income per capita?

Child labour exists in varying degrees in virtually all countries aspiring to reach high income status. The prevalence of child labour and associated criminal activities have been portrayed in the 19th century novels of Charles Dickens, perhaps most vividly in the character ‘Fagin’ in the novel ‘Oliver Twist’. It seems clear that the early years of the industrial revolution in Britain gave rise to demand for increased child labour and also provided fertile ground for criminal activities. However, it is also evident from the experience of the high-income countries that the hallowed peaks of the development process witness an end to such activities representing the dark side of income creation. This paper examines whether there is a definite relationship between country income per capita and the prevalence of crime and child labour. The presumption is that as incomes grow there is an increase in the use of child labour as well as in crime, with a tapering- off after a certain income level. This paper presents evidence for such an inverted ‘U’ relationship between child labour and income per capita as well as between the crime index and income. These findings may also throw some light on the puzzle of the sudden fall in U.S crime rates in the 1990s

Post-peak, fluid-mediated modification of granulite facies zircon and monazite in the Trivandrum Block, southern India

The quarry at Kottavattom in the Trivandrum Block of southern India contains spectacular examples of fluid-assisted alteration of high-grade metamorphic rocks. Garnet-biotite gneiss has undergone a change in mineral assemblage to form submetre scale orthopyroxene-bearing patches, later retrogressed to form an amphibole-bearing lithology. These patches, often referred to as arrested or incipient charnockite, crosscut the original metamorphic foliation and are typically attributed to passage of a low aH2O fluid through the rock. Whilst this conversion is recognised as a late stage process, little detailed chronological work exists to link it temporally to metamorphism in the region. Zircon and monazite analysed from Kottavattom not only record metamorphism in the Trivandrum Block but also show internal, lobate textures crosscutting the original zoning, consistent with fluid-aided coupled dissolution-reprecipitation during formation of the orthopyroxene-bearing patches. High-grade metamorphism at the quarry occurred between the formation of metamorphic monazite at ~585 Ma and the growth of metamorphic zircon at ~523 Ma. The fluid-assisted alteration of the garnet-biotite gneiss is poorly recorded by altered zircon with only minimal resetting of the U–Pb system, whereas monazite has in some cases undergone complete U–Pb resetting and records an age for fluid infiltration at ~495 Ma. The fluid event therefore places the formation of the altered patches at least 25 Myr after the zircon crystallisation in the garnet-biotite gneiss. The most likely fluid composition causing the modification and U–Pb resetting of zircon and monazite is locally derived hypersaline brine
