Spoken language and speech perception abilities in deaf children

Despite early diagnosis, early fitting of more advanced sensory aids, early intervention, and intensive educational management, many children with severe to profound hearing loss are delayed in their acquisition of spoken language compared with their peers with normal hearing. More...Some of the greatest challenges facing educators of deaf children include determining where to focus intervention in order to maximise benefit, and establishing the most effective strategies for the development of age-appropriate language. The experimental research in this book examined the relationship between hearing, speech production, and vocabulary knowledge, and investigated the contributions of these factors to the overall speech perception performance of deaf children. This research also investigated the areas in which intervention would be most beneficial, and examined the effects of different types of intervention on the development of spoken language and speech perception skills in deaf children. The evaluation, analysis and intervention methods reported in this book provide an experimentally validated program for improving speech perception, speech production and spoken language skills of deaf children.

The moral rights of authors and performers: an international and comparative analysis

This book is a comprehensive guide to the development and utilization of authorial moral rights across the key jurisdictions of the English-speaking world and in France and Germany. In recent years, the copyright statutes of the common law countries have been expanded by the introduction of provisions dealing with purely authorial rights - moral rights.
The Moral Rights of Authors and Performers discusses the historical development of the rights in Europe, with particular reference to France and Germany, and shows the growth of moral rights theory and legislative coverage up to the late 1930s. During the 1920s the moral rights of authors became the subject of international protection, particularly through the operation of the Berne Convention for the Protection of Literary and Artistic Works. The book explores the adoption of moral rights into this and other international instruments, explaining the functions that moral rights were intended to perform.
The author gives detailed accounts of the operation of moral rights in France and Germany today, addressing both statutory interpretation and doctrinal issues. The provision of case studies gives an impression of the rich jurisprudence associated with the rights in these countries.
The book also contains a detailed discussion of the versions of moral rights that have become entrenched in Canada, the UK, the US and Australia, with each country considered independently. It deals separately with the introduction of the rights into each country and their operation and interpretation by courts and commentators. Material on common law analogues to the rights is provided, which indicates alternative actions that practitioners might take. Problems of cross-jurisdictional legal proceedings (especially arising from technological transfer of information) are also addressed, with moral rights protection elsewhere in the world summarized in tabular form.

Toad atrial natriuretic peptide : cDNA cloning and functional analysis in isolated perfused kidneys

Complementary DNA (cDNA) encoding Bufo marinus (toad) preproatrial natriuretic peptide (preproANP) was isolated by reverse-transcription polymerase chain reaction. Sequence analysis of toad preproANP cDNA revealed an open reading frame of 150 amino acid residues, which shared 72% and 66% identity with Rana catesbeiana and Xenopus laevis preproANP, respectively. The deduced amino acid sequence of toad ANP that corresponded to ANP 1–24 of R. catesbeiana and Rana ridibunda was identical, but it differed by four residues from that of X. laevis. ANP mRNA transcripts were also shown to be expressed in the toad kidney. Subsequently, the effect of frog ANP (1–24) on renal function in toad was examined using a perfused kidney preparation. The arterial infusion of frog ANP caused a dose-dependent decrease in the arterial perfusion pressure that was associated with an increase in the glomerular filtration rate (GFR) and a renal natriuresis and diuresis. The renal natriuresis and diuresis resulted predominantly from an increased GFR rather than from direct tubular effects. This study demonstrates that ANP can regulate renal function, which suggests it may be involved in overall fluid volume regulation.

Using digital data and bibliometric analysis for researching doctoral education

As more digital data become publicly available new opportunities for researchers in education are arising. Researchers may be unaware of the existence and usefulness of such data even though these are freely available. In this article the use of one such source of information is described and its potential for research into research education discussed. We sought to exploit the research potential of the existing, yet dispersed, collection of online Australian thesis records to inform their research into the development of the PhD in Australia. Having created a searchable and reliable database from the available records, bibliometric analyses enabled us to map knowledge production and research capability in institutional and disciplinary settings from 1949 to 2003 as indicated by PhD theses. This is in contrast to the more familiar use of data based on student load or completion rates, and complements that data by focusing on research output as opposed to student throughput.

Using object and trajectory analysis to facilitate indexing and retrieval of video

This paper aims to show that by using low level feature extraction, motion and object identifying and tracking methods, features can be extracted and indexed for efficient and effective retrieval for video; such as an awards ceremony video. Video scene/shot analysis and key frame extraction are used as a foundation to identify objects in video and be able to find spatial relationships within the video. The compounding of low level features such as colour, texture and abstract object identification lead into higher level real object identification and tracking and scene detection. The main focus is on using a video style that is different to the heavily used sports and news genres. Using different video styles can open the door to creating methods that could encompass all video types instead of specialized methods for each specific style of video.

FTIR and thermal analysis of cashmere and other animal fibres

In this paper, sereval varieties of animal fibres including cashmere and Australian fine Merino wool have been analysed by Fourier transform infrared microscope and differential scanning calorimeter. The results showed that both Chinese and Australian cashmere fibres started absorbing heat at a relatively higher temperature but were thermally degraded quicker than other animal fibres tested. However, the mass changes (within the temperature range of 200oC to 350oC) and associated onset temperatures varied among fibre varieties. From the attenuated total reflectance spectra, the Chinese cashmere was clearly different from Australian cashmere and wool in a peak near 1040 cm-1 wavelength for S-O stretching of cysteic acid residues. The Chinese cashmere presented a stronger absorption at 1019 cm-1 wavelength, while Australian cashmere and wool peaked at 1079 cm-1 wavelength and had a weaker absorption. Combined with thermal analysis, the normalised R-SO3 - content of cysteic acid residues to the amide II peak of the protein backbone may have potential use in identifying Australian fine Merino wool from Chinese cashmere.

Productivity and efficiency analysis of Australia banking sector under deregulation

This paper conducts productivity and efficiency analysis of banks operating in Australia since the deregulation of the Australian financial system in early 1980s. Applying data envelopment analysis (DEA), with a moving window, the Malmquist indices are determined in order to investigate the levels of and the changes in the efficiency of Australian banks over the period from 1983 to 200 I. The DEA window analysis is adopted in order to relieve the small sample problem that in previous studies has proved problematic in the study of the Australian banking sector. The pal1icular window used in this case has been carefully designed to ensure the robustness of the efficiencies scores to changes in the window width. A second-stage regression is conducted by using the unconditional bootstrap approach suggested by Xue and Harker (1999) to overcome the dependency and heteroskedasticity of DE A efficiency scores. The empirical results demonstrate the effect of deregulation on the performance of individual banks, banks of different organizational types and the entire Australian banking sector.

Systematic review and meta-analysis of evidence for increasing numbers of drugs in antiretroviral combination therapy

Objective: To assess the evidence for the effectiveness of increasing numbers of drugs in antiretroviral combination therapy.

Design: Systematic review, meta-analysis, and meta-regression of fully reported randomised controlled trials. All studies included compared quadruple versus triple therapy, triple versus double therapy, double versus monotherapy, or monotherapy versus placebo or no treatment.

Participants: Patients with any stage of HIV infection who had not received antiretroviral therapy.

Main outcome measures: Changes in disease progression or death (clinical outcomes); CD4 count and plasma viral load (surrogate markers).
Search strategy: Six electronic databases, including Medline, Embase, and the Cochrane Library, searched up to February 2001.

Results: 54 randomised controlled trials, most of good quality, with 66 comparison groups were included in the analysis. For both the clinical outcomes and surrogate markers, combinations with up to and including three (triple therapy) were progressively and significantly more effective. The odds ratio for disease progression or death for triple therapy compared with double therapy was 0.6 (95% confidence interval 0.5 to 0.8). Heterogeneity in effect sizes was present in many outcomes but was largely related to the drugs used and trial quality.

Conclusions: Evidence from randomised controlled trials supports the use of triple therapy. Research is needed on the effectiveness of quadruple therapies and the relative effectiveness of specific combinations of drugs.

Female-perpetrated child sex abuse: definitional and categorisational analysis

A recent series of court cases in Australia in which teachers have been convicted of sexual crimes against children and adolescents has brought to attention the fact that females are capable of, and do commit, such crimes. However, the nature of the crimes does not reflect the range of sexually abusive behaviours females may perpetrate, nor the kinds of women who may engage in such behaviour. We consider definitional problems in identifying female-perpetrated sexual abuse, and note that apart from one attempt to describe the range of sexual abuse perpetrated by mothers, there is little to guide researchers or clinicians in relation to female perpetrated offences more generally. We then consider approaches to categorising female sex offenders, and conclude that, although there a several such approaches that overlap in some ways, a multidimensional approach that combines aspects of each taxonomy may be more useful.

Lipids and FA analysis of canine prostate tissue

It is widely reported that an association exists between dietary fat intake and the incidence of prostate cancer in humans. To study this association, there is a need for an animal model where prostate carcinogenesis occurs spontaneously. The canine prostate is considered a suitable experimental model for prostate cancer in humans since it is morphologically similar to the human prostate and both humans and dogs have a predisposition to benign and malignant prostate disease. In this study, the FA and lipids profiles of the normal canine prostate tissue from nine dogs were examined. The total lipid content of the canine prostate tissue was 1.7±0.5% (wet weight). The lipid composition analysis using TLC-FID showed that the two major lipid classes were phospholipids and TAG. Total FA, phospholipid, and TAG FA analysis showed that the major FA were palmitic acid (16∶0), stearic acid (18∶0), oleic acid (18∶1), linoleic acid (18∶2n−6), and arachidonic acid (20∶4n−6), The n−3 FA were present at <3% of total FA and included α-linolenic acid (18∶3n−3) (in total and TAG tissue FA), EPA (20∶5n−3) (not in TAG), and DHA (22∶6n−3) (not in TAG). The n−3/n−6 ratio was 1∶11, 1∶13, and 1∶8 in total, phospholipid, and TAG FA, respectively. This study shows the canine prostate has a low level of n−3 FA and a low n−3/n−6 ratio. This is perhaps due to low n−3 content of the diet of the dogs. FA analysis of dogfoods available in Australia showed that the n−3 content in both supermarket and premium bran dogfoods was <3% (wet weight), and the n−3/n−6 ratio was low.

The welfare economics of measuring sustainability: a new approach based on social choice theory and systems analysis

This paper presents a new measure of sustainability within a welfare economics framework. Gross domestic product (GDP) can be used as an indicator of sustainability if the GDP estimates are undertaken within a cost-benefit analysis framework based on social choice perspectives. Sustainability is dependent on a healthy and functioning socio-economic and environmental (SEE) system. Economic development can damage the SEE system through resource degradation, over-harvesting and pollution. This paper addresses the tensions between economic development and sustainability by undertaking a number of SEE-based adjustments to GDP based on social choice perspectives in order to measure sustainability. These adjustments include the environmental and social costs caused by economic development such as water pollution, the depletion of non-renewable resources, and deforestation. Thailand is used as a case study for a 25 year period (1975-1999). The results show a divergence in terms of GDP per capita and the SEE-adjusted GDP per capita figure. The paper concludes that, with increasing environmental and social costs of economic development, pursuing such extreme high growth objectives without due environmental and social considerations can threaten present social welfare and future sustainability.
