Australian children's independent mobility levels: secondary analyses of cross-sectional data between 1991 and 2012

This study investigated changes in Australian children's independent mobility levels between1991 and 2012. Data from five cross-sectional studies conducted in 1991, 1993, 2010, 2011 and 2012 were analysed. Parent and child surveys were used to assess parental licences for independent mobility and actual independent mobility behaviour in children aged 8–13 years. Findings show declines in the proportion of young children (≤10 years of age) being allowed to travel home from school alone (1991: 68%, 1993: 50%, 2010: 43%, 2011: 45%, 2012: 31%) and travel on buses alone (1991: 31%, 1993: 15%, 2010: 8%, 2011: 6%, 2012: 9%). Furthermore, the proportion of children travelling independently to school decreased (1991: 61%, 1993: 42%, 2010: 31%, 2011: 32%, 2012: 32%). Significantly fewer girls than boys travelled independently to school at each time point (p?≤?.001). Overall, the findings suggest that Australian children's independent mobility levels declined between 1991 and 2012.     

An elasticity analysis of the effectiveness of pronatalist measures in Taiwan

The total fertility rate (TFR) of Taiwan has remained below the replacement level 2.1 for past thirty years. Currently, 16 of its 22 counties and cities have TFRs below 1.3, with TFRs in middle and southern Taiwan even below 1. In the recent decade, various pronatalist policies have been adopted in Taiwan to cope with the low fertility issue. However, little is known about the effectiveness of these policies. In order to identify the group(s) of women that should be targeted to increase the TFR effectively, we have constructed a stochastic model to perform an elasticity analysis. The results show that changes in marriage rates among women aged 25–29 years would have the largest impact on the TFR, with an elasticity value of 0.32. This means that every 1 per cent increase in the marriage rate of women aged 25–29 may increase the TFR by about 0.32 per cent (i.e. an increase of about 2.6 children per 1000 women). The TFR is also very sensitive in responding to changes in the marriage rate and parity-1 fertility rate of 30–34-year-old women, with elasticities of 0.19 and 0.16 respectively. The divorce rate has a small but negative impact on the TFR. Also, the possible contribution of third- and higher-order births is insignificant. These findings suggest that policies aimed at increasing the marriage rate among women in their late twenties and early thirties, and supporting first births of women in their early thirties, are likely to raise Taiwan’s fertility rate effectively.     

The Middle Palaeolithic of the Nejd,Saudi Arabia

The Pleistocene archaeological record of the Arabian Peninsula is increasingly recognized as being of great importance for resolving some of the major debates in hominin evolutionary studies. Though there has been an acceleration in the rate of fieldwork and discovery of archaeological sites in recent years, little is known about hominin occupations in the Pleistocene over vast areas of Arabia. Here we report on the identification of five new Middle Palaeolithic sites from the Nejd of central Arabia and the southern margins of the Nefud Desert to the north. The importance of these sites centers on their diversity in terms of landscape positions, raw materials used for lithic manufacture, and core reduction methods. Our findings indicate multiple hominin dispersals into Arabia and complex subsequent patterns of behavior and demography.     

Lights,power and the moral economy of early medieval Europe

By the beginning of the early Middle Ages the convention that each church should have a light burning at all times on the altar was strongly established. This paper examines how elites promulgated this idea and benefitted from their ability to furnish lighting material (oil and wax) when this was becoming scarce and expensive. This seeming generosity helped to give the power of rulers a moral quality, but at the same time their insistence that to provide for the lights was a universal obligation meant that the social base of those who could provide for the lights broadened. It is argued here that growth in the number and types of people giving for the lights diluted the moral power that came from giving, but that it also allowed a much broader section of society to participate in the moral economy.     

Zur Bedeutung von indoiranisch *nāu̯ii̯a-

Young Avestan nāuuiia-, Old Persian nāviyā, Sanskrit nāvyà-, all descending from Indo-Iranian *nāu̯ii̯a-, are usually glossed by ‘passable (only) by boat, not to be crossed without the help of a boat’. A closer examination of the contexts they occur in reveals that the meaning ‘streaming, raging’ is much more appropriate. In consequence, *nāu̯ii̯a- can not be a secondary derivative of Indo-Iranian *nāu̯- ‘ship, boat’, which is improbable for other reasons as well. It is suggested that *nāu̯ii̯a- rather represents a primary formation derived from the Indo-Iranian root *nāu̯- ‘to flow’.
