title: Impact of Foreign Maids on Female Labor Force Participation in Malaysia

authors: Tan, Peck Leong

subjects: female labor force participation

abstract: Demand for foreign maids by households in Malaysia has increased rapidly and expected to affect female labor force participation. Simple comparisons of households with maids and those without suggest that maids raise the participation rate of their female employers by 26 percentage points. However, such comparisons are not directly comparable. Households employing maids differ in many ways from those that do not. When propensity score matching methods are used to estimate the treatment effect of having a foreign maid, the female labor force participation rate is estimated to be only 18 percentage points higher in 1993/1994 and 13 percentage points higher in 2004/2005. This decline over time in the treatment effect is not apparent when simpler but potentially biased methods are used. The small and declining impact of hiring maids suggests financial losses to the host households.

title: Processibility of corn protein blends and resulting properties of the extrudates

authors: Rosentrater, Kurt A.

abstract: During the last decade, the global biofuels industry has experienced exponential growth. By-products such as high protein corn gluten meal (CGM) and high fibre distillers dried grains with solubles (DDGS) have grown in parallel. CGM has been shown to be suitable as a biopolymer; the high fibre content of DDGS reduces its effectiveness, although it is considerably cheaper. In this study, the processing behaviour of CGM and DDGS blends were evaluated and resulting extrudate properties were determined. Prior to processing, urea was used as a denaturant. DDGS:CGM ratios of 0, 33, 50, 66 and 100% were processed in a single screw extruder, which solely used dissipative heating, with a 2 mm circular die. Resulting screw speeds ranged from 216 to 228 rpm, and die exit temperatures ranged from 96 to 150oC. Blends containing DDGS were less uniformly consolidated and resulted in more dissipative heating. Blends showed multiple glass transitions, which is characteristic of mechanically compatible blends. Transmission electron microscopy revealed phase separation on a micro-scale, although distinct CGM or DDGS phases could not be identified. On a macro-scale, optical microscopy suggested that CGM-rich blends were better consolidated, supported by visual observations of a more continuous extrudate formed during extrusion. As with all biological materials, the extruded blends exhibited sorption behaviour over time, the magnitude of which varied according to blend ratio. EMC values ranged from approximately 0% to nearly 50%, depending upon the humidity level and blend ratio. Nonlinear regression was successfully used to model the effects of relative humidity and blend ratio on the equilibrium moisture contents, with a coefficient of determination of 99%. Future work should aim to also characterize the mechanical properties of these blends to assess their suitability as either bioplastic feedstock or pelletized livestock feed.

title: Help or hindrance? New Zealand audience perspectives on subtitled media

authors: Kirk, Victoria

abstract: This research presents a picture of audiences’ patterns of engagement with internationally subtitled media in Hamilton, New Zealand. Utilising an audience reception framework to investigate audiences’ interactions with, and evaluations of subtitled media, this research unites the disciplines of Audio Visual Translation and Screen and Media Studies in a specific locale, with an emphasis on the reception of audio visual translated media. Findings in this research also provide a discussion of the wider contexts of audience reception in New Zealand, by investigating local subtitled media in relation to media accessibility processes found in the distinctive cultural landscape of New Zealand. Ultimately, this research finds the situation in New Zealand regarding audiences and the reception of both local English and Māori language media, as well as international subtitled media, exhibits complex polarisations in both the local translation industry production and audience attitudes towards bilingual media. In contrast to this, is the proliferation of international media with subtitles, which is appreciated by Hamilton residents since it provides diverse, accessible, and enjoyable content through a variety of media platforms.
