Standard setting in specific-purpose language testing: what can a qualitative study add?

This paper explores the views of nursing and medical domain experts in considering the standards for a specific-purpose English language screening test, the Occupational English Test (OET), for professional registration for immigrant health professionals. Since individuals who score performances in the test setting are often language experts rather than domain experts, there are possible tensions between what is being measured by a language test and what is deemed important by domain experts. Another concern is a lack of qualitative research on the process of the standard setting. To date, no published qualitative work has been identified about the contributions of domain experts in the standard setting for healthcare communication. In this study, a standard-setting exercise was conducted for the speaking component of the OET, using judgements of nursing and medical clinical educators and supervisors. In all, 13 medical and 18 nursing clinical educators and supervisors rated medical and nursing candidate performances respectively. These performances were audio-recorded OET role-plays that were selected across a range of proficiency levels. Domain experts were invited to comment on the basis of their decisions and the extent of alignment between these decisions and the criteria used to assess performance on the OET. Nursing and medical domain experts showed that they attended to all of the OET criteria in making their decisions about standards. However, clinical scenario simulation also invited judgements of clinical competence from participants, even where they knew that clinical competence should be excluded from their decision-making. Another concern related to the authenticity limitations of the role-play tasks as evidence of readiness to handle communication in the workplace. Overall, findings support the value of qualitative evidence from the standard setting in providing insight into the factors informing and impeding decision-making.

A multidisciplinary perspective on motor impairment as an early behavioural marker in children with autism spectrum disorder

Objectives: There is no medical test for autism spectrum disorder (ASD), a heterogeneous condition currently defined in the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5) by dysfunction in social, communication, and behavioural dimensions. There is agreement in the literature that the motor profile of ASD may hold the key to improving clinical and diagnostic definition, with DSM-5 now referring to motor deficits, including “odd gait” (p. 55), as part of the ASD clinical description. This review describes the history of motor impairment in ASD, types of motor problems, and age-related motor findings and highlights evidence gaps and future research. Method: A narrative review is provided of the research literature describing motor impairment in ASD and its ability to differentiate between ASD versus non-ASD cohorts. Results: Findings show differences in motor development in children with ASD from infancy onwards, including difficulties across motor coordination, arm movements, gait, and postural stability. Motor disturbance may appear in young children with ASD prior to social and language difficulties becoming clinically apparent. However, challenges remain in defining and measuring the early motor profile that is specific to ASD. Despite well-established motor impairments in ASD, there is a lack of evidence regarding which motor-based interventions will be effective in this group. Conclusions: Motor impairment holds promise as an early diagnostic sign, a behavioural marker, and a means by which to improve identification and possibly phenotypic delineation in ASD. Further research is required to determine whether motor abnormalities can sensitively differentiate ASD from other developmental conditions and to establish evidenced-based interventions to reduce the associated impairment.

A domain-specific visual modeling language for testing environment emulation

Software integration testing plays an increasingly important role as the software industry has experienced a major change from isolated applications to highly distributed computing environments. Conducting integration testing is a challenging task because it is often very difficult to replicate a real enterprise environment. Emulating testing environment is one of the key solutions to this problem. However, existing specification-based emulation techniques require manual coding of their message processing engines, therefore incurring high development cost. In this paper, we present a suite of domain-specific visual modelinglanguages to describe emulated testing environments at a highabstraction level. Our solution allows domain experts to model atesting environment from abstract interface layers. These layermodels are then transformed to runtime environment for application testing. Our user study shows that our visual languages are easy to use, yet with sufficient expressive power to model complex testing applications.

Culture-specific variation in the flavor profile of soymilks

A modified quantitative descriptive analysis (QDA) method was used to determine sensory profiles of 8 soymilk products: 3 manufactured in Australia, 3 manufactured in Singapore, 1 manufactured in Malaysia, and 1 manufactured in Hong Kong. A panel (n= 7) was selected, trained in descriptive profiling of soymilk, and developed a soymilk language that was used to evaluate the flavor attributes of the soymilk products. A repeated-measure ANOVA showed highly reproducible panel performance, and significant differences in soymilk attributes among all soymilks. A principal component analysis (PCA) revealed 2 main groupings among the soymilks that corresponded to cultural origin: Australia and Asia (Singapore and Hong Kong/Malaysia). Products from Australia were significantly stronger in milky, astringent, salty notes and pale in color, while products from Asia were significantly stronger in beany, cooked beans, sweet, and pandan notes (P < 0.05). In addition, the Asian soymilks could be separated into 2 subgroups, with Singaporean soymilks having deeper color, greater viscosity, and less green flavor than Hong Kong/Malaysia soymilks. Australian produced soymilk is bovine-milk-like compared with Asian soymilk, presumably due to bovine milk being the primary source of milk in Australia. We conclude that culture-specific flavor preferences are a determining factor in flavor profiles of soymilks from geographically distinct regions.

The language of design resolution in a digital building information model

Information in construction industry is delivered and interpreted in a language specific to the industry in which large complex objects are only partially described and with much information being implicit in the language used. Successful communication therefore relies on participants in the industry leaming how to interpret the language through many years of education, training and experience. With the introduction of computer technology, and in particular the detailed digital building information model (DB 1M), the accepted language currently in use is no longer a valid method of describing the building. At all stages in the paper based design and documentation process it is generally readily apparent which parts of the design require further completion and which are fully resolved. This is able to be achieved through the complex graphical language currently in use. In the DBIM, all information appears at the same level of resolution making difficult the interpretation of implicit information embedded in the model. This compromises the collaborative design environment which is being described as a fundamental characteristic of the future construction industry. This paper focuses on two areas. The first analyses design resolution and the role uncertain information plays in the design process. It then discusses the manner in which designers and the industry in general deal with incomplete or unresolved information. The second describes a theoretical model in which a design resolution (DR) environment incorporates the level of design resolution as an operable element in a collaborative DBIM. The development and implementation of this model will allow designers to better share, understand and interpret design knowledge from the shared information during the various stages of digital design and before full resolution is achieved.

Measurement of the economic impact of visual impairment from age-related macular degeneration in Australia

The purpose of this report was to: (i) outline the potential value of health economic studies into age-related macular degeneration (AMD); (ii) provide an overview of health economic studies pertinent to AMD; and (iii) outline the basic frame work of cost-of-illness studies (a useful first step in applying economic methods). The detection and management of sensory loss in the elderly plays a key role in the Australian Government's Healthy Ageing Strategy. Age-related macular degeneration is currently the leading cause of blindness in elderly Australians. Although a large proportion of AMD cases remain untreatable, the introduction of photo­dynamic therapy provides a relatively expensive and possibly cost-effective innovation for others. Antioxidant therapy has also been proven effective in reducing progression of early to late disease. The discipline of economics can contribute to an understanding of AMD prevention and treatment through: (i) describing the current burden of disease; (ii) predicting the changes in the burden of disease over time, and (iii) evaluating the efficiency of different interventions. Cost-of-illness studies have been performed in many fields of medicine. Little work, however, has been done on describing the economic impact from AMD. A number of different economic evaluation methods can be used in judging the efficiency of possible interventions to reduce the disease burden of AMD. Although complementary in nature, each has specific uses and limitations. Studies of the economic impact of eye diseases are both feasible and necessary for informed health care decision-making.

Abstracts of the Inaugural Australian Conference for Cognitive Neuropsychology and Cognitive Neuropsychiatry

The first Australian Conference for Cognitive Neuropsychology and Cognitive Neuropsychiatry was conducted by the School of Psychology at Deakin University, Geelong, from Friday, July 13 to Sunday, July 15 and was attended by over 50 cognitive psychologists, neuropsychologists and speech pathologists from Australia, New Zealand, Singapore and the UK. The Conference aimed to bring together researchers from different disciplines including linguistics, psychology, philosophy and speech pathology to present research that relates (neuropsychological or psychiatric) impairment to theories of normal cognitive functioning. The scientific program of the conference included 24 papers of exceptional quality. They were organised into the following thematic sessions: Disorders of language comprehension and production; Semantic memory and category-specific disorders; Reading: development and acquired dyslexia; Writing: development and acquired dyslexia; Memory; Object and face recognition; Theory of mind; Misidentification syndromes. Keynote speakers were Professor Andy Young from the University of York, England and Professor Max Coltheart from the Macquarie Centre for Cognitive Sciences, Sydney.

Data was collected using interview-conversations, reflective episodes, classroom observations. The research was supported by four smaller studies investigating specific aspects of curriculum, language, culture and national identity.

Developing a culturally-specific peace curriculum for Vietnamese primary schools : a case study of participatory action research in cross-cultural design

In 2003 the International Conflict Resolution Centre at the University of Melbourne, Australia, produced a primary school teaching manual for UNESCO Vietnam in consultation with ASP schoolteachers and principals. The finished manual included lessons plans and materials for a five year, 50 lesson peace education course. The Manual is one of the first examples of a systematic core national curriculum in peace education worldwide.

Development of the Teaching Manual posed a number of challenges including differences in language, culture, government and education system. To meet these challenges, a Participatory Action Research approach was central in the project’s development and curriculum design. This case study is offered as a model for effective cross-cultural curriculum development of peace education materials. In particular, the creation of a systematic core course in peace education and the use of UNESCO’s peace keys are outlined as innovative aspects of the project.

Fructose-1,6-Bisphosphatase overexpression in pancreatic [beta]-cells results in reduced insulin secretion : a new mechanism for fat-induced impairment of [beta]-cell function

Fructose-1,6-bisphosphatase (FBPase) is a gluconeogenic enzyme that is upregulated in islets or pancreatic beta-cell lines exposed to high fat. However, whether specific beta-cell upregulation of FBPase can impair insulin secretory function is not known. The objective of this study therefore is to determine whether a specific increase in islet beta-cell FBPase can result in reduced glucose-mediated insulin secretion.

To test this hypothesis, we have generated three transgenic mouse lines overexpressing the human FBPase (huFBPase) gene specifically in pancreatic islet beta-cells. In addition, to investigate the biochemical mechanism by which elevated FBPase affects insulin secretion, we made two pancreatic beta-cell lines (MIN6) stably overexpressing huFBPase.

FBPase transgenic mice showed reduced insulin secretion in response to an intravenous glucose bolus. Compared with the untransfected parental MIN6, FBPase-overexpressing cells showed a decreased cell proliferation rate and significantly depressed glucose-induced insulin secretion. These defects were associated with a decrease in the rate of glucose utilization, resulting in reduced cellular ATP levels.

Taken together, these results suggest that upregulation of FBPase in pancreatic islet beta-cells, as occurs in states of lipid oversupply and type 2 diabetes, contributes to insulin secretory dysfunction.

Self-regulation of older drivers with cognitive impairment : a systematic review

Background
Cognitive decline contributes significantly to the safety risk of older drivers. Some drivers may be able to compensate for the increased crash risk by avoiding complex driving situations or restricting their driving.

Objective and Method
A comprehensive English-language systematic review was conducted to determine the level of evidence for older adult drivers with cognitive impairment engaging in self-regulation.

Results
Twelve studies were included in the review. The majority of studies investigated driver avoidance, followed by driver restriction. Few studies ascertained the reasons for changing driving behaviour.

Conclusions
The evidence supports the view that drivers with cognitive impairment do restrict their driving and avoid complex driving situations. However, it remains to be determined whether the drivers who do engage in self-regulation require insight into their own driving abilities or whether external factors result in self-regulation of driving behaviour.

A global approach to dissecting lipid-induced impairment of liver gluconeogenesis

This thesis identified: 1) novel aspects of cholesterol metabolism, 2) a novel signalling lipid in the phosphatidylinositol class, and 3) a gene involved in regulating lipid breakdown, as being regulated in the reversal of a fatty acid induced diabetic liver. The identification of these targets may allow for future development of targeted therapies against type 2 diabetes with a specific focus on the liver.

Healthcare costs associated with language difficulties up to 9 years of age: Australian population-based study

PURPOSE: This study aimed to quantify the non-hospital healthcare costs associated with language difficulties within two nationally representative samples of children. METHOD: Data were from three biennial waves (2004-2008) of the Longitudinal Study of Australian Children (B cohort: 0-5 years; K cohort: 4-9 years). Language difficulties were defined as scores ≤ 1.25 SD below the mean on measures of parent-reported communication (0-3 years) and directly assessed vocabulary (4-9 years). Participant data were linked to administrative data on non-hospital healthcare attendances and prescription medications from the universal Australian Medicare subsidized healthcare scheme. RESULT: It was found that healthcare costs over each 2-year age band were higher for children with than without language difficulties at 0-1, 2-3, and 4-5 years, notably 36% higher (mean difference = $AU206, 95% CI = $90, $321) at 4-5 years (B cohort). The slightly higher 2-year healthcare costs for children with language difficulties at 6-7 and 8-9 years were not statistically different from those without language difficulties. Modelled to the corresponding Australian child population, 2-year government costs ranged from $AU1.2-$AU12.1 million (depending on age examined). Six-year healthcare costs increased with the persistence of language difficulties in the K cohort, with total Medicare costs increasing by $192 (95% CI = $74, $311; p = .002) for each additional wave of language difficulties. CONCLUSION: Language difficulties (whether transient or persistent) were associated with substantial excess population healthcare costs in childhood, which are in addition to the known broader costs incurred through the education system. It is unclear whether healthcare costs were specifically due to the assessment and/or treatment of language difficulties, as opposed to conditions that may be co-morbid with or may cause language difficulties.
