Migrants and the diffusion of low marital fertility in Belgium

Although the diffusion of fertility behavior between different social strata in historical communities has received considerable attention in recent studies, the relationship between the diffusion of fertility behavior and the diffusion of people (migration) during the nineteenth century remains largely underexplored. Evidence from population registers compiled in the Historical Database of the Liège Region, covering the period of 1812 to 1900, reveals that migrant couples in Sart, Belgium, from 1850 to 1874 and from 1875 to 1899 had a reduced risk of conception. The incorporation of geographical mobility, as well as the migrant status of both husbands and wives, into this fertility research sheds light not only on the spread of ideas and behaviors but also on the possible reasons why the ideas and behaviors of immigrants might have been similar to, or different from, those of a native-born population.     

Rapid denudation of Higher Himalaya during late Pliestocence, evidence from OSL thermochronology

Optically Stimulated Luminescence (OSL) of quartz, with closure temperatures of 30–35°C in conjunction with Apatite Fission Track (AFT; closure temp. ～120°C) and ⁴⁰Ar-³⁹Ar (biotite closure temperature ～350°C), were used to obtain cooling ages from Higher Himalayan crystalline rocks of Western Arunachal Himalaya (WAH). Cooling age data based on OSL, AFT and Ar-Ar thermochronology provide inference on the exhumation — erosion history for three different time intervals over million to thousand year scale. Steady-state exhumation of ～0.5 mm/yr was observed during Miocene (>7.2 Ma) till Early Pleistocene (1.8 Ma). Onset of Pleistocene glacial/interglacial conditions from ～1.8 Ma formed glaciated valleys and rapid erosion with rivers incising deep valleys along their course. Erosion enables midcrustal partial melts to move beneath the weak zone in the valley and causes an erosion-induced tectonic uplift. This resulted in a rapid increase in exhumation rate. The OSL thermochronology results suggest increased erosion over ～21 ka period from Late Pleistocene (2.5 mm/yr) to Early Holocene (5.5 mm/yr) and these are to be contrasted with pre 1.8 Ma erosion rate of 0.5 mm/yr. Enhanced erosion in the later stage coincides with the periods of deglaciation during Marine Isotope Stages (MIS) 1 and 2. The results of the present study suggest that in the present setting OSL thermochronology informed on the short-term climatic effect on landscape evolution and techniques like the AFT and ⁴⁰Ar-³⁹Ar provided longer-term exhumation histories.     

High-resolution radiocarbon dating of marine materials in archaeological contexts: radiocarbon marine reservoir variability between Anadara, Gafrarium, Batissa, Polymesoda spp. and Echinoidea at Caution Bay, Southern Coastal Papua New Guinea

The remains of shellfish dominate many coastal archaeological sites in the Pacific and provide a wealth of information about economy, culture, environment and climate. Shells are therefore the logical sample type to develop local and regional radiocarbon chronologies. The calibration of radiocarbon (¹⁴C) dates on marine animals is not straightforward, however, requiring an understanding of habitat and dietary preferences as well as detailed knowledge of local ocean conditions. The most complex situations occur where terrestrial influences impinge on the marine environment resulting in both the enrichment and depletion of ¹⁴C (Ulm Geoarchaeology 17(4):319–348, 2002; Petchey and Clark Quat Geochronol 6:539–549, 2011). A sampling protocol that combines a high-resolution excavation methodology, selection of short-lived samples identified to species level, and a tri-isotope approach using ¹⁴C, δ¹³C and δ¹⁸O, has given us the ability to identify ¹⁴C source variation that would otherwise have been obscured. Here, we present new research that details high-resolution mapping of marine ¹⁴C reservoir variation between Gafrarium tumidum, Gafrarium pectinatum, Anadara granosa, Anadara antiquata, Batissa violacea, Polymesoda erosa and Echinoidea from the Bogi 1 archaeological site, Caution Bay, southern coastal Papua New Guinea. These isotopes highlight specific dietary, habitat and behavioural variations that are key to obtaining chronological information from shell radiocarbon determinations.     

Youth–community–university partnerships and sense of place: two case studies of youth participatory action research

This paper describes two youth participatory action research initiatives undertaken in East Palo Alto, CA, USA, as part of university–community partnerships. We discuss the process of engaging youth researchers to build youth skills, facilitate relationships with community-based organizations, and enhance study integrity. We report interview and artifact data that address: (1) how the youths' involvement in the research process affected their sense of place and self-efficacy for creating community change; (2) how the youths' interactions with adult community leaders shifted adult perceptions of youths' abilities and roles in the community; and (3) how the initiatives affected youth and adult participants' perspectives of the university.     

Between Two Paradigms: Harriet Pullen and the Earliest Australian Female Preachers

This article focuses on an eye‐witness account of a series of sermons preached in Brown's River, Tasmania, in 1836–1838 by Harriet Pullen — arguably the earliest documented instance of female preaching in Australia. It explores the context, motivation, and reception of Harriet's preaching, comparing it with the two main paradigms of female preachers that can be found in the contemporary literature: the preacher as “prophetess” and the preacher as “helpmeet.” While Harriet has much in common with both paradigms, she does not fit neatly into either. Her preaching activity is best understood as a convergence of the two paradigms, within a context of domestic church gatherings in a frontier missionary situation.     

Helping the Rich get Richer: A Re-assessment of the Income Distributional Trend in Hong Kong

Although many are under the impression that income inequality in Hong Kong has been continually on the rise, the picture presented by official statistics is mixed. This article suggests that official statistics, due to limitations in their design, have underestimated the impact of the top earners. Utilising taxation data, a continuous and strong growth in inequality can be identified when the distribution among taxpayers is considered, providing an alternative picture of inequality in Hong Kong. It is argued that the surge in income inequality is driven in part by the rich earning more rather than by more people becoming rich. The Hong Kong government, instead of adopting redistributive measures to alleviate the situation, has exacerbated inequality through policy choices that strongly favour the richest group. Although these actions might be explained in relation to the political influence wielded by the business sector and the upper class, the social implications of inequality cannot be neglected. Apart from a stronger demand for democracy, perceptions of income inequality and the pro-rich bias in the political system significantly affect people’s political views, as seen in the support for the recent Occupy Movement.
