Social change, migration and pregnancy intervals

Maternity histories from residents of a Pacific Island society, Tokelau, and migrants to New Zealand, are analysed using life table techniques. Inter-cohort differentials in patterns of family formation were found in the total Tokelau-origin population. The process of accelerated timing and spacing of pregnancies was more pronounced among migrants who tended to marry later, be pregnant at marriage, have shorter inter-pregnancy intervals at lower parities and to show evidence of family limitation occurring at higher parities. These results point to the significance of changing patterns of social control on strategies of family building

Microwave-assisted hydrothermal synthesis of carbon monolith via a soft-template method using resorcinol and formaldehyde as carbon precursor and pluronic F127 as template

A new microwave-assisted hydrothermal synthesis of carbon monolith is reported in this work. The process uses microwave heating at 100 °C under acidic condition by employing a triblock copolymer F127 as the template, and resorcinol–formaldehyde as the carbon precursor. Scanning electron microscopy, Fourier transform infrared spectroscopy, nitrogen sorption measurements, transmission electron microscopy, X-ray studies and thermogravimetic analysis were used to characterize the synthesized material. The carbon monolith is crack-free, mesoporous and has a high surface area of 697 m²/g. The results demonstrate that the microwave-assisted hydrothermal synthesis is a fast and simple approach to obtain carbon monoliths, as it reduces effectively the synthesis time from hours to a few minutes which could be an advantage in the large scale production of the material

Letter from Robert E. Prior to James B. Finley

Prior writes asking Finley to help bring about the pardon of his brother James, who is in prison and very ill. Governor Bebb is aware of the situation, but Finley will need to advocate for James\u27 release. Abstract Number - 1102https://digitalcommons.owu.edu/finley-letters/2086/thumbnail.jp

Letter from Robert E. Prior to James B. Finley

Prior writes concerning his incarcerated brother, James Prior, who is ill. In order to request a pardon for James from Governor Bebb, Prior needs two letters -- one from Finley attesting to the reformation of James\u27 character, and one from the attending physician at the prison, confirming that confinement is dangerous for James\u27 health.

Orientation and Alignment Echoes

We present what is probably the simplest classical system featuring the echo phenomenon - a collection of randomly oriented free rotors with dispersed rotational velocities. Following excitation by a pair of time-delayed impulsive kicks, the mean orientation/alignment of the ensemble exhibits multiple echoes and fractional echoes. We elucidate the mechanism of the echo formation by kick-induced filamentation of phase space, and provide the first experimental demonstration of classical alignment echoes in a thermal gas of CO_2 molecules excited by a pair of femtosecond laser pulses

Mixtapes and Turntablism: DJs’ Perspectives on Musical Shape

The notion of musical shape is widely used by performing musicians, but most studies have focussed on classical performing contexts. This paper extends this research to DJs performing on turntables, chosen in light of existing evidence from a questionnaire study suggesting that shape may be a useful concept for some DJs. This paper presents an interview study investigating the use and understanding of musical shaping by three professional DJs with varied backgrounds. Interpretative Phenomenological Analysis was used to analyse the data. Findings suggest that DJs do use the notion of shape implicitly when planning and executing their sets, and that playing sets without any shaping involves playing the music badly. DJs reported using the idea of shaping to modify a track while it was playing; to help control the transition between tracks; and in relation to the overall trajectory of a set. There was evidence that participants understood musical shaping multi-modally, through gesture and visual representation as well as sound; and results show ways in which DJs draw on heuristics to signify complex combinations of technical devices that create a particular musical shape or sound. The findings are considered in relation to existing work on performers’ use of musical shape as well as work on the practice of DJs

Evaluating residents’ preferences for remediation technologies: A choice experiment approach

© 2017 Elsevier B.V. The choice of technologies used to remediate contaminated environments is increasingly made through engagement with a multitude of stakeholders including affected residents. Despite this, little is known about how residents perceive remediation technology applications. In this study a choice experiment is designed to explore ways of understanding and measuring residents’ preferences for different remediation technologies approaches using a sample of 944 residents in New South Wales, Australia. Analysis reveals that the residents’ acceptability of remediation technologies can be explained by both the efficacy of the technology in improving the environmental quality of the community, and the reputational value of the technology. In particular it is found that residents prefer Monitor Natural Attenuation and Bioremediation to other remediation technologies. In particular they are willing to pay an increase in yearly taxes of $44.60 and$41.15 respectively for implementing such technologies instead of alternative remediation technologies like Chemical remediation
