Objective and subjective measurements of office meeting rooms

This research is a preliminary investigation of the objective measurements ofthelmal comfort and C02 levels as well as subjective user evaluation surveys in six meeting rooms. The ongoing objective measurements were taken via thelmal comfort carts while the surveys evaluated parameters of temperature, lighting, air quality, meeting effectiveness etc. The outcomes are of particular interest since some of the objective measurements clearly to not support those of the users. In fact, the investigation has triggered off further interest in refining questionnaires to develop more precise indicators of 'discomfort'.
Furthelmore, meeting rooms present a challenge when it comes to conditioning spaces (HV AC design) which are sporadic in use and often with high occupancy for short periods. This paper investigates meeting rooms in four different buildings and their conditioning control concepts are discussed in relation to measured results.

Development of monoclonal antibodies against Vibrio pathogens

Monoclonal antibodies were developed against pathogenic vibrios for use in rapid identification in disease situations of humans, fish and shellfish. Of the 12 fusions performed using V. alginolyticus, V. anguillarum, V. carchariae, V. cholerae, V. damsela, V. furnissii, V. harveyi, V. ordalii, V. parahaemolyticus and V. vulnificus, a total of 102 hybridomas were obtained. Based on cross-reactivity of a wide range of Vibrio strains and other gram-negative bacteria, three broad types of monoclonal antibodies were found. The three categories were: (1) ones that were species-specific or specific to a particular surface antigen, (2) a large number that reacted with several Vibrio species, and (3) three that reacted with most Vibrio strains but no other gram-negative bacteria. Each species-specific monoclonal antibody only recognized its corresponding Vibrio species and was used for identifying unknown species, confirming diagnosis of clinical isolates. In addition, several monoclonal antibodies only cross-reacted with similar Vibrio species, e.g. V. parahaemolyticus and V. alginolyticus which share a common H-antigen. Monoclonal antibodies reacting with several Vibrio species were not of particular use in diagnostic situations. Three monoclonal antibodies of the last group did not react with other genera of the family Vibrionaceae, namely Aeromonas, Photobacterium and Plesiomonas nor a wide range of gram-negative enteric bacteria. These data indicated the existence of an antigenic surface determinant common to Vibrio species. One monoclonal reacted with the heat-stable antigenic determinants on the cell surface as v as lipopolysaccharide extracted from all the vibrios studied, thus making it useful for large- scale screening of acute infections of vibrios. In a blind test, seven Vibrio species, isolated from 6 marine and a freshwater source were identified by two laboratories using phenetic tests. Results of immunotyping using monoclonals, three of seven were diagnosed as the same species, another three were designated as Vibrio species but could not be classified further due to the library not having the corresponding monoclonal, and one was diagnostically questionable. Two further tests were carried out. An unknown Vibrio formalin-fixed isolated from diseased marine animal was identified as V. parahaemolyticus by ELISA and FITC. Clinical human isolates of V. alginolyticus, V. parahaemolyticus and V. vulnificus were confirmed by monoclonals. Australian isolates of V. anguillarum appeared to be mostly of serotype O1. monoclonals raised to V. anguillarum AFHRL 1 reacted with only serotype O1 from Denmark but also most Australian isolates. All vibrios pathogenic to fish and shellfish, i.e. V. anguillarum, V. ordalii, V. alginolyticus, V. carchariae, V. cholerae, V. damsela, V. harveyi, V. parahaemolyticus and V. vulnificus, were used for attachment studies to fish cells using phase contrast and FITC-immunofluorescence microscopy. Of these vibrios, V. anguillarum, V. ordalii and V. perahaemolyticus, were found to adhere to different cells and tissues of rainbow trout while others did not appear to attach. However, attachment was inhibited by monoclonal antibodies specific to only these three vibrios. Lipopolysaccharide is well known as being a contributing factor in pathogenicity of gram-negative bacteria. PAGE electrophoresis of extracted LPS from 9 strains covering 6 Vibrio species showed the presence of a common 15,000 D fragment. This fragment was verified by immunoblotting with a genus-specific monoclonal antibody (i.e. F11P411F) recognizing nearly all vibrios. The common LPS fragment was separated and used to raise polyclonal antisera in mouse which reacted strongly with LPS itself, live as well as sodium azide-killed vibrios, but not with other gram-negative bacteria. This raised the possibility of developing vaccine from Vibrio LPS. Monoclonal antibodies developed in the present study enabled rapid identification of a number of pathogenic Vibrio species. There is still further work to produce monoclonal antibodies against additional vibrios that are probably pathogenic. These included V. fluvialis, V. hollisae, V. metschnikovii, V. minicus, V. salmonella and V. tubiashii. Together the application will be of significance in clinical diagnostic work, in the monitoring of vibriosis in fish farms and in quarantine.

New evidence on purchasing power parity from 17 OECD countries

There is a large literature that investigates whether or not real exchange rates are stationary in an attempt to unravel support for purchasing power parity (PPP). At best, the empirical results are mixed. This paper applies a unit root test that allows for a simultaneous structural break in the intercept and slope, shown by Sen (2003) to minimize power distortions, to examine PPP for 17 OECD countries. Our results on PPP are mixed. When the real exchange rate is based on the US dollar, evidence is found of PPP for only France, Portugal and Denmark. When the real exchange rate is based on the Deutschmark, we find evidence of PPP for Austria, Belgium, Norway, Spain, Netherlands, Switzerland, and Denmark.

Global education : travel and new imaginaries for teachers' work

This workshop reports on Learning across Latitude - a trans-national collaborative project that joined teacher education students from Australia, Denmark and Malaysia. The project offered a unique opportunity for students to explore concepts and dialogue with their teacher education peers in three countries. Over a two week period, 116 students in 13 forums posted 365 messages into a forum space hosted by Deakin University. 
During week 1, students introduced themselves to each other and discussed their reasons to become teachers, qualities of a good teacher and the issues facing teaching in their country. Because many students life experiences are local in experience such a project expands notions of being a teacher in a global world. Student’s responses to qualities of a good teacher were analysed to build knowledge of global teacher identities.
During week 2 students discussed what it means to be a good citizen in their country. How is citizenship as a concept explained across three countries? In the virtual discussions for Malaysian and Danish students, English was a second language. These forums opened new awareness for all students of the challenges of conversing with English as second language students.
This project illustrated that the changing contexts of education and globalisation means new opportunities and challenges for teacher education at local and global levels. Implications from Learning across Latitudes suggest possibilities for teacher education to build global citizenship, and teacher identities as technology enables such possibilities.

What decision rules might pink-footed geese use to depart on migration? An individual-based model

Decisions taken during migration can have a large effect on the fitness of birds. Migration must be accurately timed with food availability to allow efficient fueling but is also constrained by the optimal arrival date at the breeding site. The decision of when to leave a site can be driven by energetics (sufficient body stores to fuel flight), time-related cues (internal clock under photoperiodic control), or external cues (temperature, food resources). An individual based model (IBM) that allows a mechanistic description of a range of departure decision rules was applied to the spring migration of pink-footed geese (Anser brachyrhynchus) from wintering grounds in Denmark to breeding grounds on Svalbard via 2 Norwegian staging sites. By comparing predicted with observed departure dates, we tested 7 decision rules. The most accurate predictions were obtained from a decision rule based on a combination of cues including the amount of body stores, date, and plant phenology. Decision rules changed over the course of migration with the external cue decreasing in importance and the time-related cue increasing in importance for sites closer to breeding grounds. These results are in accordance with descriptions of goose migration, following the “green-wave”: Geese track the onset of plant growth as it moves northward in spring, with an uncoupling toward the end of the migration if time is running out. We demonstrate the potential of IBMs to study the possible mechanisms underlying stopover ecology in migratory birds and to serve as tools to predict consequences of environmental change.

Soft matter : from shapes to forces on the nanoscale

Soft matter deforms in response to imposed external forces. Here we demonstrate how dynamic surface forces are linked to far-field deformations. This offers a new paradigm for determining forces between soft particles in colloidal systems. The particular example we use to illustrate this concept is that of a fluid drop interacting with a solid wall through hydrodynamic drainage flow coupled with repulsive or attractive dissimilar electrical double layer interactions. The force can be deduced from a simple analysis of the drop surface geometry outside the interaction zone.

Feasibility of repeated 24-h dietary recalls combined with a food-recording booklet, using EPIC-Soft, among preschoolers

Background/Objectives: This study evaluates the feasibility among preschoolers of the 224-h dietary recalls (24-HDRs) method combined with a food-recording booklet (FRB), using EPIC-Soft pc-program for the 24-HDR (the software developed to conduct 24-HDRs in the European Prospective Investigation into Cancer and Nutrition (EPIC) Study).
Subjects/Methods: A total of 20 and 25 (4- to 5-year-old) children were recruited, as a convenience sample, through worksites or day or healthcare in Denmark and Spain, respectively. One parent (or both parents together) completed two face-to-face 24- HDR, combined with an optional use of a FRB. Feasibility was evaluated by evaluation questionnaires completed by parents and interviewers.
Results: The face-to-face interviews were primarily conducted with the mothers. The FRB was used by 90% of the participants, and proxy persons, other than the parent, were also involved; involvement of proxy persons seems necessary in a majority of the recalls in both the countries.
Conclusions: The results suggest that 224-HDR with one parent combined with a FRB is feasible for registering preschoolers’ diet. An FRB and/or information from proxy persons, other than the parent, is needed for a majority of the parents. In future studies, it may be beneficial to develop the FRB more like a structured food record (FR), which might, in principle, change the method to a one-day FR method from more than a 24-HDR method. It is recommended then to further investigate the use of EPIC-Soft as a data-entry tool.

Homework through the eyes of children : what does visual ethnography invite us to see?

Whilst the notion of children’s rights and an entitlement to express their views and participate as global citizens is threaded throughout the international policy field, children’s perspectives on the near ubiquitous practice of homework, and its effects on their daily lives and learner subjectivities, remain under-researched. Drawing on the Bourdieuian concepts of practice, habitus, capital and field, this article develops a cross-cultural analysis of homework practices in Australia, Denmark and Britain to make visible the embodied habitus and agentic possibilities shaping the reproduction of educational advantage and disadvantage for variously located students. Using video data generated by children in primary schools, the article explores children’s visual representations of their compliance and resistance to homework’s regulatory functions. It demonstrates the affordances of visual ethnographic methods as a form of participatory research with children which foregrounds students’ experiences and opinions and makes visible the inclusionary and exclusionary effects of homework on children in diverse socio-cultural settings.

Self-management needs during life transitions among younger people with type 2 diabetes : an Australian and Danish cohort comparison

The primary aim of this pilot study is to provide cross-cultural and detailed insights into how psychological and social factors impact on younger people with type 2 diabetes (T2DM) and self-management skille (20-40 years). The specific objectives are to: identify self-management strategies used by younger people with T2DM during life transitions in the period from 20-40 years of age; investigate participants' perception of self-management to identify the specific needs of younger people with T2DM. This research will provide health professionals with insights to the specific needs for young adults with T2DM and will add ground breaking innovative information by investigating cultural comparison between Australia and Denmark.

Does the availability of snack foods in supermarkets vary internationally?

Background
Cross-country differences in dietary behaviours and obesity rates have been previously reported. Consumption of energy-dense snack foods and soft drinks are implicated as contributing to weight gain, however little is known about how the availability of these items within supermarkets varies internationally. This study assessed variations in the display of snack foods and soft drinks within a sample of supermarkets across eight countries.

Methods
Within-store audits were used to evaluate and compare the availability of potato chips (crisps), chocolate, confectionery and soft drinks. Displays measured included shelf length and the proportion of checkouts and end-of-aisle displays containing these products. Audits were conducted in a convenience sample of 170 supermarkets across eight developed nations (Australia, Canada, Denmark, Netherlands, New Zealand, Sweden, United Kingdom (UK), and United States of America (US)).

Results
The mean total aisle length of snack foods (adjusted for store size) was greatest in supermarkets from the UK (56.4 m) and lowest in New Zealand (21.7 m). When assessed by individual item, the greatest aisle length devoted to chips, chocolate and confectionery was found in UK supermarkets while the greatest aisle length dedicated to soft drinks was in Australian supermarkets. Only stores from the Netherlands (41%) had less than 70% of checkouts featuring displays of snack foods or soft drinks.

Conclusion
Whilst between-country variations were observed, overall results indicate high levels of snack food and soft drinks displays within supermarkets across the eight countries. Exposure to snack foods is largely unavoidable within supermarkets, increasing the likelihood of purchases and particularly those made impulsively.

Sharing good NEWS across the world: developing comparable scores across 12 countries for the neighborhood environment walkability scale (NEWS)

Background: The IPEN (International Physical Activity and Environment Network) Adult project seeks to conduct pooled analyses of associations of perceived neighborhood environment, as measured by the neighborhood Environment Walkability Scale (NEWS) and its abbreviated version (NEWS-A), with physical activity using data from 12 countries. As IPEN countries used adapted versions of the NEWS/NEWS-A, this paper aimed to develop scoring protocols that maximize cross-country comparability in responses. This information is also highly relevant to non-IPEN studies employing the NEWS/NEWS-A, which is one of the most popular measures of perceived environment globally.
Methods: The following countries participated in the IPEN Adult study: Australia, Belgium, Brazil, Colombia, Czech Republic, Denmark, Hong Kong, Mexico, New Zealand, Spain, the United Kingdom, and the United States. Participants (N = 14,305) were recruited from neighborhoods varying in walkability and socio-economic status. Countries collected data on the perceived environment using a self- or interviewer-administered version of the NEWS/NEWS-A. Confirmatory Factor Analysis (CFA) was used to derive comparable country-specific measurement models of the NEWS/NEWS-A. The level of correspondence between standard and alternative versions of the NEWS/NEWS-A factor-analyzable subscales was determined by estimating the correlations and mean standardized difference (Cohen’s d) between them using data from countries that had included items from both standard and alternative versions of the subscales.
Results: Final country-specific measurement models of the NEWS/NEWS-A provided acceptable levels of fit to the data and shared the same factorial structure with six latent factors and two single items. The correspondence between the standard and alternative versions of subscales of Land use mix – access, Infrastructure and safety for walking/cycling, and Aesthetics was high. The Brazilian version of the Traffic safety subscale was highly, while the Australian and Belgian versions were marginally, comparable to the standard version. Single-item versions of the Street connectivity subscale used in Australia and Belgium showed marginally acceptable correspondence to the standard version.
Conclusions: We have proposed country-specific modifications to the original scoring protocol of the NEWS/NEWS-A that enhance inter-country comparability. These modifications have yielded sufficiently equivalent measurement models of the NEWS/NEWS-A. Some inter-country discrepancies remain. These need to be considered when interpreting findings from different countries.

The gardens on Anlaby - a utopian dream

Anlaby Station is the oldest sheep stud in South Australia (SA) dating back to 1839. The gardens have been noted as significant exemplars, Beames & Whitehill (1992), Swinbourne (1982), and in Pastoral Homes of Australia (1911) published by The Pastoral Review, wherein Anlaby was described as “being of no particular beauty architecturally . But the gardens are unique.” The Anlaby property is on the SA State Heritage Register and the Anlaby Gardens are listed in the Oxford Companion to Australian Gardens (2002). The beginnings of Anlaby in 1839 are integral to the colonial expansion of the interior of South Australia. Anlaby at this time was a completely self-contained community within a sheep station containing a survival garden, much like a self- contained English manor-village. The process of land sales offered by the SA government enabled Anlaby to expand, wherein wealth flowed and gradually the survival garden style at Anlaby was transformed into an extensive decorative garden style. This enabled the garden to act as a backdrop for major South Australian society and public gatherings. The driving force behind the garden during its height was the fashionable plant trends in the United Kingdom. This is evidenced by the inclusion of an extensive stove house, grotto, roses and the Gardenesque style of plantings. Traditional English head gardeners were also employed to manage the garden. The realisation of the beauty of native plants was never allowed in the inner world of this landscape; it always remained on the perimeter. The owner’s vision of the garden was Utopian, however, due to climatic forces, the dream was not fully realised. The challenge now lies in preserving this Utopian dream for future generations. This paper considers the historical evolution of the property, its context as a historical exemplar and the challenges facing its future conservation having regard to Adelaide peri-urban, climate change, and differing owner economic circumstances.
