An evaluation framework for the qualitative investigation of a physical activity prescription program in rural Victoria

Physical activity (PA) has consistently been shown to improve ones' physical, social and mental health. Hence, the rationale for promoting regular physical activity is relatively straightforward. However, what is less clear from the literature is the mix of strategies, (i.e. 'what is working and why?'), to increase in physical activity levels within a population. Of particular interest to primary care is the concept of Physical Activity Prescription Programs (PAPPs) delivered by general practitioners (GPs).

Several examples of a PAPP exist within England, America, New Zealand and Australia. These all aim to encourage GPs to deliver physical activity advice to their patients effectively and in a timely manner. Notwithstanding, the authors of a recent review of published literature on PAPPs, reveal a deficit of evidence regarding the components for successful PA interventions.

This research through an ethnographic enquiry aims to build on the evidence formulated to date. Through a case study research design, the researcher has developed a methodology to define what is/is not working within this recent trend.

In two rural Divisions of GP, participants have been identified as key stakeholders in the implementation of a PAPPs. They are categorised according to three theoretical paradigms, namely, Policy Makers, Linkers and Adaptors. Following this the three paradigms will be studied on the contextual factors, the characteristics and behaviours of members within all three paradigms. The study has also further defined certain elements for investigation, these include the:
intention of the players
effort undertaken by players, and
effect of parties within.

Primarily qualitative data will be collected; through Desk Analysis (Policies, Strategic and Business plans), Site Visits (Participant Observation) and semi-structured interviews. This presentation defines a qualitative framework and methodology for investigating the outcome of programs that historically has been evaluated using quantitative measures. Hence, the author of this study aims to present a qualitative investigation and subsequent results, defining aspects of a PAPP that allow for successful and sustainable implementation.

Skills and qualities and the effective project manager in the UK construction industry

The professional project manager is a sought after commodity (McManus, 1995:12). Many companies face increasing demands to complete projects faster, at lower costs and to higher specifications and as Lock (1996;50) comments; “This work, far from requiring specialisation, demands a sufficient general understanding of the work carried out by those participants for the project manager to be able to discuss the work sensibly”. Though for some the term project manager can be clearly identified, others believe the terms project manager and project management, as used in the construction industry, mean all things to all men and lead to confusion (The Chartered Institute of Building, 1982;12). The lack of clarity surrounding the role of project manager made this area worthy of investigation.

This research sought a deeper understanding of the project management role and an identification of the skills and professionals associated with it. The desk top study revealed definitions of the role and perceptions of the skills involved. The literature showed that authors believed in the need for a balance between knowledge, experience and training and the types of professions involved. The research methodology comprised a qualitative approach, with a questionnaire sent out to a non-random sample of practices specialising in project management. The data analysis adopted uni and bi-variant methods, using SPSS. The research found that the role of the project manager is very broad. Furthermore it is adopted by many construction professions as the background of the project manager is largely perceived as irrelevant to the role. A definition is proposed and relevant skills are identified, finally the importance of experience and training is highlighted.

The emergence of the global workplace : opportunities and barriers for building surveyors in Oceania

The Royal Institution of Chartered Surveyors (RICS) the professional body representing surveyors in the UK, has implemented a policy to globalise in order to meet the challenges and opportunities the global marketplace was creating for its members as well as protecting and serving its interests (RICS, 1999). Quantity surveyors had a presence and history of employment outside the UK, particularly in the Middle and Far East. Real estate surveyors found the transition to working in European Union (EU) countries relatively straightforward and numerous UK real estate organisations have European, Asian, North American and Oceanic offices. Additionally UK based firms establishing partnerships with overseas real estate firms expanded significantly over the previous decade. Building Surveying is different. Small numbers worked in commonwealth countries but in most countries their professional and academic qualifications were not recognised. With the changes implemented by the RICS, this paper examines the barriers and opportunities facing RICS Chartered Building Surveyors (CBS) in Oceania (taken as Australia, New Zealand, Papua New Guinea and Fiji).

A desk top study reviewed the political, economic and sociological variables affecting employment opportunities and professional services which were put to the RICS Oceania Building Surveying Faculty. No previous study had been undertaken to identify the specific barriers and opportunities in Oceania for the BS and this research adopted a census survey of RICS practitioners currently employed in the region and the results form the most comprehensive picture of the current position. The findings are that some of the opportunities and barriers will change in significance over time. The main barriers to growth were perceived as lack of support from a Euro focussed RICS and the difficulties associated with being perceived as outsiders. Opportunities were perceived as emerging in new areas of professional services such as sustainability and energy efficiency.

Computational media aesthetics: Finding meaning beautiful

Innovative media management, annotation, delivery, and navigation services will enrich online shopping, help-desk services, and anytime-anywhere training over wireless devices. However, the semantic gap between the rich meaning that users want when they query and browse media and the shallowness of the content descriptions that one can actually compute is weakening today's automatic content-annotation systems. To address such problems, an approach that markedly departs from existing methods based on detecting and annotating low-level audio-visual features is advocated.

The development of the Melbourne low vision ADL index : a measure of vision disability

PURPOSE. To develop a new test of activities of daily living (ADLs) appropriate for the low-vision population: the Melbourne Low-Vision ADL Index (MLVAI).

METHODS. The MLVAI was designed as a desk-based clinical assessment, comprising 18 observed items on complex ADLs in part (a) and 9 questions on broad self-care ADLs in part (b). Each item was rated on a five-level descriptive scale from 0 to 4, based on independence, speed, and accuracy of performance. It was designed to be administered under standardized conditions with regard to the instructions, illumination, and working distances. The validity and reliability of the new MLVAI was determined for 122 subjects who were representative of the general low-vision population, in a cross-sectional study.

RESULTS. Two items were found to be redundant and were eliminated from the test. Thus, the final test comprised 25 items, with 100 being the highest possible score. Cronbach’s α indicated an internal reliability of 0.96, and an intraclass correlation coefficient indicated an overall reliability of 0.95. The SE of measurement was 4.5. According to Spearman’s correlation coefficient, the test–retest reliability was 0.94 (P < 0.001), and the interpractitioner reliability for five different pairs of practitioners was 0.90 or higher (P < 0.001). With regard to validity, there was a moderately high correlation with vision impairment (r = −0.68, P < 0.001). Using Rasch analysis, content validity was also demonstrated by good separation indexes (4.70 and 9.88) and high reliability scores (0.96 and 0.99) for the person and items parameters, respectively. Separate calculation of indexes and reliability scores for parts (a) and (b) indicated high content validity and reliability of each part. However, the separation indexes and reliability scores were higher for part (a) than for part (b). The correlation coefficient for part (a) and part (b) was 0.68.

CONCLUSIONS. The MLVAI is a highly valid and reliable standardized test of ADL performance for the general low-vision population. It may be used to assess patients with low vision and has the potential to be used as a measure of low-vision rehabilitation outcomes.

A weighted version of the Melbourne low-vision ADL index : a measure of disability impact

Objective. To develop a version of the Melbourne Low-Vision ADL Index that measures the personal impact of disability in activities of daily living (ADL's). Also, to determine the relationship between clinical measures of vision impairment and disability impact.

Methods. The Melbourne Low-Vision ADL Index (MLVAI) is a desk-based clinical assessment of disability in ADL's. Ability to perform each item is rated on a five-level descriptive scale from zero to four. In this study, the original version of the MLVAI was modified to measure disability impact. The simple modification involved weighting each item by the importance of that item to the person being tested. Importance was also rated on a five-level scale from zero to four. The validity and reliability of the Weighted Melbourne Low-Vision ADL Index (MLVAIW) was determined for 97 vision-impaired subjects in a cross-sectional study.

Results. Cronbach's alpha coefficient indicated an internal reliability of 0.94, and an intraclass correlation coefficient indicated an overall reliability of 0.88. The standard error of measurement was 24.7 points (out of a possible score of 400). There was a statistically significant difference in test scores between normal subjects and vision-impaired subjects. All vision measures had a high, statistically significant correlation with MLVAIW score. Near-word acuity had the strongest correlation (rs = 0.78, p < 0.001), followed by Melbourne Edge Test contrast sensitivity (rs = -0.72, p < 0.001). Visual field had the weakest correlation (rs = -0.52, p < 0.001). The best predictive model of MLVAIW score incorporated the variables age, near-word acuity, and visual field. Together, these variables accounted for 65.1% of the variance in MLVAIW score.

Conclusions. The MLVAI is highly valid and reliable when weighted by a scale that reflects the personal importance of ADL's. The MLVAIW can provide information over and above that obtained with the usual clinical vision measures and may be used to assess low-vision patients and to measure low-vision rehabilitation outcomes. It is suggested that the assessment of disability using the original MLVAI and the assessment of the impact of disability using the MLVAIW should be kept separate to facilitate the clear interpretation of the outcomes of low-vision rehabilitation.

Reducing office workers' sitting time: rationale and study design for the Stand Up Victoria cluster randomized trial

Background
Excessive time spent in sedentary behaviours (sitting or lying with low energy expenditure) is associated with an increased risk for type 2 diabetes, cardiovascular disease and some cancers. Desk-based office workers typically accumulate high amounts of daily sitting time, often in prolonged unbroken bouts. The Stand Up Victoria study aims to determine whether a 3-month multi-component intervention in the office setting reduces workplace sitting, particularly prolonged, unbroken sitting time, and results in improvements in cardiometabolic biomarkers and work-related outcomes, compared to usual practice.

Methods/design
A two-arm cluster-randomized controlled trial (RCT), with worksites as the unit of randomization, will be conducted in 16 worksites located in Victoria, Australia. Work units from one organisation (Department of Human Services, Australian Government) will be allocated to either the multi-component intervention (organisational, environmental [heightadjustable workstations], and individual behavioural strategies) or to a usual practice control group. The recruitment target is 160 participants (office-based workers aged 18–65 years and working at least 0.6 full time equivalent) per arm. At each assessment (0- [baseline], 3- [post intervention], and 12-months [follow-up]), objective measurement via the activPAL3 activity monitor will be used to assess workplace: sitting time (primary outcome); prolonged sitting time (sitting time accrued in bouts of ≥30 minutes); standing time; sit-to-stand transitions; and, moving time. Additional outcomes assessed will include: non-workplace activity; cardio-metabolic biomarkers and health indicators (including fasting glucose, lipids and insulin; anthropometric measures; blood pressure; and, musculoskeletal symptoms); and, work-related outcomes (presenteeism, absenteeism, productivity, work performance). Incremental cost-effectiveness and identification of both workplace and individual-level mediators and moderators of change will also be evaluated.

An accountability framework to promote healthy food environments

Objective
To review the available literature on accountability frameworks to construct a framework that is relevant to voluntary partnerships between government and food industry stakeholders.

Design
Between November 2012 and May 2013, a desk review of ten databases was conducted to identify principles, conceptual frameworks, underlying theories, and strengths and limitations of existing accountability frameworks for institutional performance to construct a new framework relevant to promoting healthy food environments.

Setting
Food policy contexts within high-income countries to address obesity and diet-related non-communicable diseases.

Subjects Eligible resources (n 26) were reviewed and the guiding principles of fifteen interdisciplinary frameworks were used to construct a new accountability framework.

Results
Strengths included shared principles across existing frameworks, such as trust, inclusivity, transparency and verification; government leadership and good governance; public deliberations; independent bodies recognizing compliance and performance achievements; remedial actions to improve accountability systems; and capacity to manage conflicts of interest and settle disputes. Limitations of the three-step frameworks and ‘mutual accountability’ approach were an explicit absence of an empowered authority to hold all stakeholders to account for their performance.

Conclusions
We propose a four-step accountability framework to guide government and food industry engagement to address unhealthy food environments as part of a broader government-led strategy to address obesity and diet-related non-communicable diseases. An independent body develops clear objectives, a governance process and performance standards for all stakeholders to address unhealthy food environments. The empowered body takes account (assessment), shares the account (communication), holds to account (enforcement) and responds to the account (improvements).

Learning latent activities from social signals with hierarchical dirichlet processes

Understanding human activities is an important research topic, most noticeably in assisted-living and healthcare monitoring environments. Beyond simple forms of activity (e.g., an RFID event of entering a building), learning latent activities that are more semantically interpretable, such as sitting at a desk, meeting with people, or gathering with friends, remains a challenging problem. Supervised learning has been the typical modeling choice in the past. However, this requires labeled training data, is unable to predict never-seen-before activity, and fails to adapt to the continuing growth of data over time. In this chapter, we explore the use of a Bayesian nonparametric method, in particular the hierarchical Dirichlet process, to infer latent activities from sensor data acquired in a pervasive setting. Our framework is unsupervised, requires no labeled data, and is able to discover new activities as data grows. We present experiments on extracting movement and interaction activities from sociometric badge signals and show how to use them for detecting of subcommunities. Using the popular Reality Mining dataset, we further demonstrate the extraction of colocation activities and use them to automatically infer the structure of social subgroups. © 2014 Elsevier Inc.

Workplace sitting breaks questionnaire (SITBRQ): an assessment of concurrent validity and test-retest reliability

Breaks in prolonged sitting may have beneficial cardiometabolic and musculoskeletal health outcomes. Desk-based work settings are an important environment to promote and support breaks in sitting time. However, few studies have reported the psychometric properties of self-report measures to assess the frequency and duration of breaks from sitting. This study examined the concurrent validity and test-retest reliability of the Workplace Sitting Breaks Questionnaire (SITBRQ) designed to assess frequency and duration of breaks in sitting within desk-based work settings.

Desenvolvimento de uma abordagem para a inserção da simulação no setor hospitalar de Porto Alegre

Esta dissertação apresenta uma abordagem para inserção e aplicação da técnica de Simulação Computacional como ferramenta de apoio a análise de decisão no setor hospitalar. Um grupo de onze hospitais foi contemplado diretamente no estudo. O processo de inserção da ferramenta foi implementado em quatro macro etapas. As duas primeiras etapas envolveram a totalidade do grupo de hospitais e objetivaram a divulgação da ferramenta; foram elas: (i) Pesquisa para diagnosticar o conhecimento e interesse do grupo na técnica, e (ii) realização de seminários para divulgação da técnica. As duas macro etapas finais caracterizam um estudo de caso, tendo sido desenvolvidas em um hospital; foram elas: (iii) Estudo-Piloto com desenvolvimento de um modelo computacional utilizando um software dedicado, no qual o grupo do hospital foi treinado, e (iv) utilização do modelo na definição das características de um novo serviço de atendimento. Durante todo o processo onze hospitais participaram da pesquisa realizada, aproximadamente cem pessoas assistiram a pelo menos um dos seminários e um hospital desenvolveu um estudo aplicado de simulação. Neste estudo a simulação foi utilizada para analisar alternativas para uma situação específica no hospital e um novo serviço alternativo foi criado a partir da análise realizada e do modelo desenvolvido. O resultado decorrente da simulação foi implementado na prática. Pode-se constatar neste trabalho o grande interesse dos hospitais em técnicas que auxiliem a tomada de decisão.
