Out-of-home food outlets and area deprivation: case study in Glasgow, UK

Background
There is a popular belief that out-of-home eating outlets, which typically serve energy dense food, may be more commonly found in more deprived areas and that this may contribute to higher rates of obesity and related diseases in such areas.

Methods
We obtained a list of all 1301 out-of-home eating outlets in Glasgow, UK, in 2003 and mapped these at unit postcode level. We categorised them into quintiles of area deprivation using the 2004 Scottish Index of Multiple Deprivation and computed mean density of types of outlet (restaurants, fast food restaurants, cafes and takeaways), and all types combined, per 1000 population. We also estimated odds ratios for the presence of any outlets in small areas within the quintiles.

Results
The density of outlets, and the likelihood of having any outlets, was highest in the second most affluent quintile (Q2) and lowest in the second most deprived quintile (Q4). Mean outlets per 1,000 were 4.02 in Q2, 1.20 in Q4 and 2.03 in Q5. With Q2 as the reference, Odds Ratios for having any outlets were 0.52 (CI 0.32–0.84) in Q1, 0.50 (CI 0.31 – 0.80) in Q4 and 0.61 (CI 0.38 – 0.98) in Q5. Outlets were located in the City Centre, West End, and along arterial roads.

Conclusion
In Glasgow those living in poorer areas are not more likely to be exposed to out-of-home eating outlets in their neighbourhoods. Health improvement policies need to be based on empirical evidence about the location of fast food outlets in specific national and local contexts, rather than on popular 'factoids'.

Access to a healthy diet and fast foods in the City of Casey

It is known that the consumption of fast food is associated with obesity (Binkley 2000). Relative ease of access to fast foods compared with healthy foods may contribute to the increasing prevalence of obesity. The aim of this study was to determine and compare the access by car to fast foods and a healthy diet. The study was located in the City of Casey, a municipality in South East Melbourne with a population of 220,000. We have previously shown that ease of access to a large chain supermarket ensures access to a basket of healthy foods adequate to meet the nutritional needs of a family of 6 (Burns 2004). The City of Casey council provided location details for major fast food outlets and supermarkets. Fast food was defined as food sourced from an outlet without table service. We included only those major fast food chain outlets which had more than 10 franchises within Australia. We included the 3 major supermarket chains that account for 87% total food retailing in Victoria. Geographic details from the City of Casey were used to map the location of these outlets. Then using these locations and road network a basic cost distance model was created for either the supermarket chains or fast food chains outlets. The cost unit is (time), it was to calculate by giving the roads in the network an average travel speed depending in the type of road (minor, major or highway) and then calculating how long it would take to reach the closest outlet. Access to supermarket and fast food outlets were determined relative to population density.
Our results indicate that in the City of Casey most (> 80%) people live within an 8-10 minute car journey of a major supermarket and a fast food outlet. Fifty percent of the fast food outlets are co-located with a supermarket. We conclude that access to both healthy food and fast food in the City of Casey is good if you own a car. The increasing demand for fast food is easily met in this municipality. Obesity prevention strategies in Casey should concentrate on the food choices available at fast food outlets and town planning to ensure a mix of food outlets to maximize the likelihood of healthy food choices.

Publishing in 20 leading marketing journals – an examination of global performance

Purpose of this paper was to examine the global contribution of academics to marketing literature between 1999 and 2003. This was done based on an examination of the location of academics institution of employment, as reported in published works within the targeted journals. This was then used to examine the globally dispersion of publishing by institutions.

Design/approach. The paper used a content analysis. The authorship of all articles in 20 leading journals was examined between 1999 and 2003. Empirical examination of institutions performance was undertaken across geographic regions. There was also an examination of whether the type of journal impacted on regional performance, using Polonsky and Whitelaw’s (2006) A, B and C journal groupings.

Findings. The research found that there is a significant “bias” of authorship within the 20 journals examined, with the majority of works published by academics at institutions in North America. There is some variation in regional performance based on the type of journal examined. However, when one considers the number of universities within each country/region, it is identified that the proportion of institutions within a country/region publishing within the targeted journals is in fact hight outside North America.

Limitations. There was no attempt to examine why any differences exist. The study also only focused on a sample of 20 English language journals over 5 years, although these journals have been ‘defined’ as a leading marketing journal for European marketing academics.

Practical Implications. The research suggests that there may in fact be a range of differences in publishing behaviour. It is unclear if these differences relate to variations in the “objectives” of institutions within each country or other factors. The research posits that a marketing knowledge may be unnecessarily restricted, if there is a bias against non-north American perspectives.

Originality. While there have been other works examining research performance of institutions, there have not been any marketing-related works that focused on the nation in which authors work. This work therefore takes a global “snapshot” of national research performance within marketing.

An examination of the globalisation of authorship in publishing in 20 leading marketing journals

Purpose – The purpose of this paper is to examine the global contribution of academics to marketing literature between 1999 and 2003, based on an examination of the location of academics institution of employment, as reported in published works. The data is used to evaluate the global dispersion of publishing.

Design/methodology/approach – The paper uses the method of content analysis where the authorship of all articles in 20 leading marketing journals between 1999 and 2003 is examined. An empirical examination of performance was undertaken across geographic regions. There was also an examination of whether the quality of journal affected regional performance.

Findings – The research found that there is a significant “bias” of authorship within the 20 journals examined, with the majority of works published by academics at institutions in North America. There is some variation in regional performance based on the type of journal examined.

Research limitations/implications – There was no attempt to empirically examine why differences might exist. The study only focused on a sample of 20 English language journals over five years. These journals have been included in studies that list the leading marketing journal for US and European academics.

Practical implications – The research suggests that there may in fact be regional differences in publishing behaviour. It is unclear if these differences relate to variations in the “objectives” of institutions within each country or other factors, such as the North American publish-or-perish mentality. The research posits that a marketing knowledge may be unnecessarily restricted, if there is a bias against non-North American perspectives.

Originality/value – While there have been other works examining research performance of institutions, there has been limited examination in marketing on the nation in which authors work and none have used a broad cross-section of journals. This work takes a global “snapshot” of national research performance within marketing.

Microclimatic modeling of the urban thermal environment of Singapore to mitigate urban heat island

This study investigates the urban heat island effect in Singapore and examines the key factors causing this effect. The possibilities of improving heat extraction rate by optimizing air flow in selected hot spots were explored. The effect of building geometry, façade materials and the location of air-conditioning condensers on the outdoor air temperature was explored using computational fluid dynamics (CFD) simulations. It was found that at very low wind speeds, the effect of façade materials and their colours was very significant and the temperature at the middle of a narrow canyon increased up to 2.5 °C with the façade material having lower albedo. It was also found that strategically placing a few high-rise towers will enhance the air flow inside the canyon thereby reducing the air temperature. Adopting an optimum H/W ratio for the canyons increased the velocity by up to 35% and reduced the corresponding temperature by up to 0.7 °C.

Interrogating 'imagined' communities : exploring the impact of international students in local schools

This paper suggests new directions understanding the impact of international students in schools. It is concerned with the ways that community representatives discuss these students and their impact on the community of the school. Recent literatures describe communities such as those of schools as ones of perception and materiality whereby some are included differently than others. Discourses such as multiculturalism and monoculturalism, which have traditionally shaped these discussions about community relations, have always been ambivalent. They take on new forms as local/global interaction, and the individualistic and market-driven changes that lead to the arrival of international students have consequences for the everyday lives of school community members. These need to be investigated if the location of international students in local school communities is to be properly described and interrogated.

Evaluation of the implementation of a state government community design policy aimed at increasing local walking : design issues and baseline results from RESIDE, Perth Western Australia

Objectives.
To describe the design and baseline results of an evaluation of the Western Australian government's pedestrian-friendly subdivision design code (Liveable Neighborhood (LN) Guidelines).
Methods.

Baseline results (2003–2005) from a longitudinal study of people (n = 1813) moving into new housing developments: 18 Liveable, 11 Hybrid and 45 Conventional (i.e., LDs, HDs and CDs respectively) are presented including usual recreational and transport-related walking undertaken within and outside the neighborhood, and 7-day pedometer steps.
Results.

At baseline, more participants walked for recreation and transport within the neighborhood (52.6%; 36.1% respectively), than outside the neighborhood (17.7%; 13.2% respectively). Notably, only 20% of average total duration of walking (128.4 min/week (SD159.8)) was transport related and within the neighborhood. There were few differences between the groups' demographic, psychosocial and perceived neighborhood environmental characteristics, pedometer steps, or the type, amount and location of self-reported walking (p > 0.05). However, asked what factors influenced their choice of housing development, more participants moving into LDs reported aspects of their new neighborhood's walkability as important (p < 0.05).
Conclusions.

The baseline results underscore the desirability of incorporating behavior and context-specific measures and value of longitudinal designs to enable changes in behavior, attitudes, and urban form to be monitored, while adjusting for baseline residential location preferences.

Depth estimation of metallic objects using multiwavelets scale-space representation

The problem of dimensional defects in aluminum die-castings is widespread throughout the foundry industry and their detection is of paramount importance in maintaining product quality. Due to the unpredictable factory environment and metallic with highly reflective nature, it is extremely hard to estimate true dimensionality of these metallic parts, autonomously. Some existing vision systems are capable of estimating depth to high accuracy, however are very much hardware dependent, involving the use of light and laser pattern projectors, integrated into vision systems or laser scanners. However, due to the reflective nature of these metallic parts and variable factory environments, the aforementioned vision systems tend to exhibit unpromising performance. Moreover, hardware dependency makes these systems cumbersome and costly. In this work, we propose a novel robust 3D reconstruction algorithm capable of reconstructing dimensionally accurate 3D depth models of the aluminum die-castings. The developed system is very simple and cost effective as it consists of only a pair of stereo cameras and a defused fluorescent light. The proposed vision system is capable of estimating surface depths within the accuracy of 0.5mm. In addition, the system is invariant to illuminative variations as well as orientation and location of the objects on the input image space, making the developed system highly robust. Due to its hardware simplicity and robustness, it can be implemented in different factory environments without a significant change in the setup. The proposed system is a major part of quality inspection system for the automotive manufacturing industry.

Position estimation and tracking of an autonomous mobile sensor using received signal strength

In this paper, an algorithm for approximating the path of a moving autonomous mobile sensor with an unknown position location using Received Signal Strength (RSS) measurements is proposed. Using a Least Squares (LS) estimation method as an input, a Maximum-Likelihood (ML) approach is used to determine the location of the unknown mobile sensor. For the mobile sensor case, as the sensor changes position the characteristics of the RSS measurements also change; therefore the proposed method adapts the RSS measurement model by dynamically changing the pass loss value alpha to aid in position estimation. Secondly, a Recursive Least-Squares (RLS) algorithm is used to estimate the path of a moving mobile sensor using the Maximum-Likelihood position estimation as an input. The performance of the proposed algorithm is evaluated via simulation and it is shown that this method can accurately determine the position of the mobile sensor, and can efficiently track the position of the mobile sensor during motion.

Sensory characterization of the irritant properties of oleocanthal, a natural anti-inflammatory agent in extra virgin olive oils

Oleocanthal is an olive oil phenolic possessing anti-inflammatory activity. Anecdotal evidence suggests that oleocanthal elicits a stinging sensation felt only at the back of the throat (oropharynx). Due to this compound possessing potentially health-benefiting properties, investigation into the sensory aspects of oleocanthal is warranted to aid in future research. The important link between the perceptual aspects of oleocanthal and health benefits is the notion that variation in sensitivity to oleocanthal irritation may relate to potential differences in sensitivity to the pharmacologic action of this compound. The current study assessed the unique irritant attributes of oleocanthal including its location of irritation, temporal profile, and individual differences in the perceived irritation. We show that the irritation elicited by oleocanthal was localized to the oropharynx (P < 0.001) with little or no irritation in the anterior oral cavity. Peak irritation was perceived 15 s postexposure and lasted over 180 s. Oleocanthal irritation was more variable among individuals compared with the irritation elicited by CO₂ and the sweetness of sucrose. There was no correlation between intensity ratings of oleocanthal and CO₂ and oleocanthal and sucrose (r = –0.15, n = 50, P = 0.92 and r = 0.17, n = 84, P = 0.12, respectively), suggesting that independent mechanisms underlie the irritation of CO₂ and oleocanthal. The unusual spatial localization and independence of acid (CO₂) sensations suggest that distinct nociceptors for oleocanthal are located in the oropharyngeal region of the oral cavity.

Characterisation of nickel(II) extraction by 2-hydroxy-5-nonylacetophenone oxime (LIX 84) in a micellar phase

The properties of the nickel(II)/2-hydroxy-5-nonylacetophenone oxime (HNAPO), an active ingredient in LIX 84, extraction system were characterised in a micellar system. The extinction coefficient, λ_max of HNAPO (316 nm) and the Ni²⁺ complex (387 nm) in a neutral micellar system, poly dispersed octa-ethyleneglycol mono-n-dodecyl ether (G₁₂A₈) were determined as 3100 and 3500 M⁻¹ cm⁻¹, respectively. HNAPO was found to have a neutral micellar phase and bulk aqueous phase pK_a of 11.5 and 12.5, respectively. The extraction equilibrium constant, K_ex, was determined to be 10^−8.0, and the deviation from theory observed at high pH can be accounted for by consideration of the competition for nickel(II) ions by hydroxide ions and HNAPO. A micellar phase of octa-ethyleneglycol mono-n-dodecyl ether (C₁₂E₈) was determined to be an appropriate model of the free oil/water interface from the solubilised location of HNAPO. Utilising the interfacial probe, 4-heptadecyl-7-hydroxy coumarin (HHC) allowed the determination of the electrostatic surface potential of mixed micelles of G₁₂A₈ and sodium dodecyl sulphate (SDS) or dodecyl trimethyl ammonium chloride (DTAC). The electrostatic surface potential was a linear function of the number of additional surfactant monomers within the G₁₂A₈ micelle, for the concentration range studied. For G₁₂A₈/DTAC mixed micelles, the surface potential was given by +1.1 mV per DTAC molecule per micelle, and for G₁₂A₈/SDS mixed micelles the relationship was −1.4 mV per SDS molecule per micelle.

Women's views of postnatal care in the context of the increasing pressure on postnatal beds in Australia

Background : Despite limited evidence evaluating early postnatal discharge, length of hospital stay has declined dramatically in Australia since the 1980s. The recent rising birth rate in Victoria, Australia has increased pressure on hospital beds, and many services have responded by discharging women earlier than planned, often with little preparation during pregnancy. We aimed to explore the views of women and their partners regarding a number of theoretical postnatal care ‘packages’ that could provide an alternative approach to early postnatal care.

Methods : Eight focus groups and four interviews were held in rural and metropolitan Victoria in 2006 with participants who had experienced a mix of public and private maternity care. These included 8 pregnant women, 42 recent mothers and 2 male partners. All were fluent in English. Focus groups explored participants’ experiences and/or expectations of early postnatal care in hospital and at home and their views of alternative packages of postnatal care where location of care shifted from hospital to home and/or hotel. This paper describes the packages and explores and describes what ‘value’ women placed on the various components of care.

Findings : Overall, women expressed a preference for what they had experienced or expected, which may be explained by the ‘what is must be best’ phenomenon where women place value on the status quo. They generally did not respond favourably towards the alternative postnatal care packages, with concerns about any shorter length of hospital stay, especially for first time mothers. Women were concerned about the safety and wellbeing of their new baby and reported that they lacked confidence in their ability to care for their baby. The physical presence and availability of professional support was seen to alleviate these concerns, especially for first time mothers. Participants did not believe that increased domiciliary visits compensated for forgoing the perceived security and value of staying in hospital. Women generally valued staying in hospital for the length of time they felt they needed above all other factors.

Key conclusions and implications for practice : Women were concerned about shortened postnatal length of hospital stay and these concerns must be considered when changes are planned in maternity service provision. Any moves towards shorter postnatal length of stay must be comprehensively evaluated with consideration given to exploring consumer views and satisfaction. There is also a need for flexibility in postnatal care that acknowledges women's individual needs.

Assuming responsibility : teachers taking charge of their professional development

The paper reports on some of the findings of an extensive study undertaken in Victoria as part of a national Science, ICT and Mathematics Education in Rural and Regional Australia (SiMERR) project. One of the significant findings of the study was the extent to which teachers in the schools where the study data were collected took responsibility for many aspects of their own professional development. This was not at the expense of, but rather was in addition to, their involvement in school- and region-based professional development activity. The study also identifies some of the challenges faced, mostly related to the location of their schools in a rural or regional setting.

Mineral law and the doctrine of rights : a microscope of magnification?

The doctrine of rights has become part of private law jurisprudence. In this article the application of the doctrine in two decisions dealing with surface support in mineral law is examined. It is argued that the decision of Kriegler J in Elektrisiteitsvoorsieningskommissie v Fourie, namely, that the right to surface support is an entitlement, is more correct than Anglo Operations Ltd v Sandhurst Estates (Pty) Ltd in which it was decided that the right to surface support is a competence. It is submitted that depending on the legal location of the entitlement in the relationship between owner and miner of land one may simply refer to either an owner's entitlement to surface support or a miner's entitlement to undertake opencast-cast mining.

Spatial patterns of a southern bell frog litoria raniformis population in an agricultural landscape

We investigated changes in the spatial organization of individuals within a population of endangered Southern Bell Frogs Litoria raniformis over an eight-month period. Our results identified strong temporal changes in both spatial organization and the apparent location of L. raniformis within the study site. Ripley's K Function analyses showed that the position of individuals relative to one another shifted from random immediately after the study site was flooded (p < 0.005), to strongly clustered at spatial scales between 0-1 500 m during the peak breeding period (p < 0.005). The majority of flooded areas were dry by April and May and individuals again became aggregated within the remaining waterbodies.
