Environmental Aid and Economic Development in the Third World
Climate change has a profound impact on the planet, especially on developing countries – as highlighted by the Stern Report to the British government in 2006. One solution to mitigating environmental degradation and achieving better outcomes appears to be through the provision of aid to poor countries. Using newly available data from the PLAID (Project-Level Aid) database project, we ask what determines the level of environmental aid to developing countries – and in particular whether such aid is affected by the level of economic development of the recipient country. At the same time, we investigate whether economic development is affected by the receipt of environmental aid. Implicit in the second question, of course, is the notion that, besides addressing the ecological outcomes, environmental aid may have the potential to enhance the economic prosperity of poor countries.Economic Development; Aid; Developing Countries
A developed country approach to eliminating blinding trachoma
In Australia trachoma is endemic, only in pockets among aboriginal people. The TF prevalence in school-age children in 2002−2003 ranged from 0−27% (district) and 0−60% (community).4 Trichiasis in indigenous adults in highly disease-endemic communities over the age of 40 years is approximately 10%. There are limited data on face-washing, but a survey of three schools in 2004 gave rates of 55%. The rate of latrine use and access to water is almost universal (96%)
Audit of Antenatal Testing of Sexually Transmissible Infections and Blood Borne Viruses at Western Australian Hospitals
In August 2007, the Western Australian Department of Health (DOH) released updated recommendations for testing of sexually transmissible infections (STI) and blood-borne viruses (BBV) in antenates. Prior to this, the Royal Australian & New Zealand College of Obstetricians & Gynaecologists (RANZCOG) antenatal testing recommendations had been accepted practice in most antenatal settings. The RANZCOG recommends that testing for HIV, syphilis, hepatitis B and C be offered at the first antenatal visit. The DOH recommends that in addition, chlamydia testing be offered. We conducted a baseline audit of antenatal STI/BBV testing in women who delivered at selected public hospitals before the DOH recommendations.
We examined the medical records of 200 women who had delivered before 1st July 2007 from each of the sevenWAhospitals included in the audit. STI and BBV testing information and demographic data were collected. Of the 1,409 women included, 1,205 (86%) were non-Aboriginal and 200 (14%) were Aboriginal. High proportions of women had been tested for HIV (76%), syphilis (86%), hepatitis C (87%) and hepatitis B (88%). Overall, 72% of women had undergone STI/BBV testing in accordance with RANZCOG recommendations. However, chlamydia testing was evident in only 18% of records. STI/BBV prevalence ranged from 3.9% (CI 1.5– 6.3%) for chlamydia, to 1.7% (CI 1–2.4%) for hepatitis C, 0.7% (CI 0.3–1.2) for hepatitis B and 0.6% (CI 0.2–1) for syphilis.
Prior to the DOH recommendations, nearly three-quarters of antenates had undergone STI/BBV testing in accordance with RANZCOG recommendations, but less than one fifth had been tested for chlamydia. The DOH recommendations will be further promoted with the assistance of hospitals and other stakeholders. A future audit will be conducted to determine the proportion of women tested according to the DOH recommendations.

Why HITnet kiosks didn\u27t hit the mark for sexual health education of Western Australian Aboriginal youth
Objective: To assess the use, appropriateness of, and staff feedback on specific sexual health modules, which were installed on Heuristic Interactive Technology (HITnet) kiosks at Aboriginal Community Controlled Health Services (ACCHS). The HITnet kiosks were aimed at Aboriginal youth visiting these sites.
Methods: Modules on the HITnet kiosks were assessed for (1) cultural appropriateness using Yunkaporta’s Aboriginal pedagogy framework and (2) compliance with the World Health Organization’s (WHO) advice on key elements for comprehensive sexual health education for young people. Data measuring kiosk use were obtained through HITnet kiosk activity reports. An online survey of ACCHS staff was used to qualitatively assess use of, and staff perceptions of, HITnet kiosks.
Results: Kiosk modules were consistent with seven of the eight elements of Yunkaporta’s framework and all of the WHO recommendations. The most popular module generated 3,066 purposeful sessions and the least popular module generated 724 purposeful sessions across nine sites in 2012. While teenagers were the most frequent of the kiosk user groups (39.5% in 2012), the majority of users (56%) were not in the target group (i.e. elders 4%, adults 25%, children 27%). Key issues reported by ACCHS staff (n=11) included: lack of clarity regarding staff responsibility for overseeing kiosk functionality; kiosks attracting “inappropriate ages”; and “lack of privacy” based on kiosk location, screen visibility, and absence of headphones preventing discreet access.
Conclusions: The modules were tailored to a young Aboriginal audience through technology thought to be appealing to this group. However, barriers to use of the kiosk included kiosk design features, location, and lack of clarity around responsibility for kiosk operation.
Implications: Aboriginal youth need easy access to sexual health messages in a ‘safe’, non-judgmental space. Information and communication that is accessible via personal and mobile devices may be a better vehicle than public kiosks
Machine requirements planning and workload assignment using genetic algorithms
This paper presents a genetic approach to determining the optimal number of machines required in a manufacturing system for meeting a specified production schedule. This use of genetic algorithms is illustrated by solving a typical machine requirements planning problem. Comparison of the respective results obtained by using the proposed approach and a standard mixed-integer programming package shows that the proposed approach is indeed an effective means for optimal manufacturing systems design.published_or_final_versio
Production Performance of Broilers fed different Feed Additives
A study of the production performance of broilers fed different feed additives (Lactozyme, Jimplex,
and Nutrifac), indicated no significant difference among the treatment means concerning feed consumption
and feed conversion. For weight gain, there was a significant difference (P<0.05) between the
Jimplex and Control groups. Broilers from the Jimplex group were 5.92% heavier and had a higher income
over feed cost per bird by $0.13 when compared to those from the con trol group at 63 days of age
The use of "Pruteen1" in broiler diets
A study, involving 1,200 birds., was conducted to compare the performance of birds fed pruteenbased
and commercial diets. The mean individual feed intake, weight gain and feed conversion ratio (F.eR.)
of birds fed the pruteen-based diet were 4673.8 g, 2172.3 g and 2.15 respectively, whereas in those fed
the commercial diet they were 4832.5 g, 2151.8 g and 2.25 respectively. Birds fed the pruteen-based diet
consumed significantly less feed and had better F. C.R. (P < 0.05). However the difference of 20.5 g in
weight gain/bird in favour of the pruteen-based diet was not found to be significant. Mortality figures of
4.5% and 3.8% respectively of birds fed pruteen-based and commercial diets were considered normal.
There was a difference of $0. 0878 in the feed cost/bird in favour of the pruteen-based diet
Chlamydia trachomatis and the risk of spontaneous preterm birth, babies who are born small for gestational age, and stillbirth: A population-based cohort study
Background: Chlamydia trachomatis is one of the most commonly diagnosed sexually transmitted infections worldwide, but reports in the medical literature of an association between genital chlamydia infection and adverse obstetric outcomes are inconsistent.
Methods: The Western Australia Data Linkage Branch created a cohort of women of reproductive age by linking records of birth registrations with the electoral roll for women in Western Australia who were born from 1974 to 1995. The cohort was then linked to both chlamydia testing records and the state perinatal registry for data on preterm births and other adverse obstetric outcomes. We determined associations between chlamydia testing, test positivity, and adverse obstetric outcomes using multivariate logistic regression analyses.
Findings: From 2001 to 2012, 101558 women aged 15 to 38 years had a singleton birth. Of these women, 3921 (3·9%) had a spontaneous preterm birth, 9762 (9·6% of 101371 women with available data) had a baby who was small for gestational age, and 682 (0·7%) had a stillbirth. During their pregnancy, 21267 (20·9%) of these women had at least one chlamydia test record, and 1365 (6·4%) of those tested were positive. Before pregnancy, 19157 (18·9%) of these women were tested for chlamydia, of whom 1595 (8·3%) tested positive for chlamydia. Among all women with a test record, after adjusting for age, ethnicity, maternal smoking, and history of other infections, we found no significant association between a positive test for chlamydia and spontaneous preterm birth (adjusted odds ratio 1·08 [95% CI 0·91–1·28]; p=0·37), a baby who was small for gestational age (0·95 [0·85–1·07]; p=0·39), or stillbirth (0·93 [0·61–1·42]; p=0·74).
Interpretation: A genital chlamydia infection that is diagnosed and, presumably, treated either during or before pregnancy does not substantially increase a woman’s risk of having a spontaneous preterm birth, having a baby who is small for gestational age, or having a stillbirth.

Chaplygin gas dominated anisotropic brane world cosmological models
We present exact solutions of the gravitational field equations in the
generalized Randall-Sundrum model for an anisotropic brane with Bianchi type I
geometry, with a generalized Chaplygin gas as matter source. The generalized
Chaplygin gas, which interpolates between a high density relativistic era and a
non-relativistic matter phase, is a popular dark energy candidate. For a
Bianchi type I space-time brane filled with a cosmological fluid obeying the
generalized Chaplygin equation of state the general solution of the
gravitational field equations can be expressed in an exact parametric form,
with the comoving volume taken as parameter. In the limiting cases of a stiff
cosmological fluid, with pressure equal to the energy density, and for a
pressureless fluid, the solution of the field equations can be expressed in an
exact analytical form. The evolution of the scalar field associated to the
Chaplygin fluid is also considered and the corresponding potential is obtained.
The behavior of the observationally important parameters like shear, anisotropy
and deceleration parameter is considered in detail.Comment: 13 pages, 6 figures, accepted for publication in PR
The Influence of Gamma-rays on the Injury and Chromosomal Aberrations of Long Bean (Vigna sesquipedalis, Fruw.)
The effects of gamma-rays on three varieties of long bean (Vigna sesquipedalis, Fruw), namely
Melaka, Local Black and Local Long were studied using Jive doses ranging from 10 to 50 kR. Both
Chromosomal aberrations and characteristics related to physiological damage were used to study
radiation sensitivity of the varieties. In general, gamma radiation did not affect % seed germination
but caused a significant reduction in characteristics related to survival, growth and fertility. Percentage
chromosomal aberrations also increased with increasing dose. As the measurement of seedling
height is simple, quick and highly correlated with most characteristics studied, it could be a useful
parameter in the study of radiation effects on long bean. Using a critenrion of approximately 30%
reduction in seedling height or 50% lethality, it is suggested that doses ranging from 30 to 50 kR
would be suitable for mutation induction in long bean
