Progress on salt reduction in the Pacific Islands: from strategies to action

BACKGROUND: Most populations are consuming too much salt which is the main contributor of high blood pressure, a leading risk factor of cardiovascular disease and stroke. The South Pacific Office of the World Health Organization has been facilitating the development of salt reduction strategies in Pacific Island Countries and areas (PICs). The objective of this analysis was to review progress to date and identify regional actions needed to support PICs and ensure they achieve the global target to reduce population salt intake by 30% by 2025.
METHODS: Relevant available national food, health and non-communicable disease (NCD) plans from all 22 PICs were reviewed. NCD co-ordinators provided updates and relayed experiences through semi-structured interviews. All activities were systematically categorised according to an existing salt reduction framework for the development of salt reduction strategies.
RESULTS: Salt reduction consultations had been held in 14 countries and final strategies or action plans developed in nine of these, with drafts available in a further three. Three other countries had integrated salt reduction into NCD strategic plans. Baseline monitoring of salt intake had been undertaken in three countries, salt levels in foods in nine countries and salt knowledge, attitude and behaviour surveys in four countries. Most countries were at early stages of implementation and identified limited resources as a barrier to action. Planned salt reduction strategies included work with food industry or importers, implementing regional salt reduction targets, reducing salt levels in school and hospital meals, behaviour change campaigns, and monitoring and evaluation.
CONCLUSIONS: There had been good progress on salt reduction planning in PICs. The need for increased capacity to effectively implement agreed activities, supported by regional standards and the establishment of improved monitoring systems, were identified as important steps to ensure the potential cardiovascular health benefits of salt reduction could be fully realised in the region.

Performance analysis and prediction in triathlon

Performance in triathlon is dependent upon factors that include somatotype, physiological capacity, technical proficiency and race strategy. Given the multidisciplinary nature of triathlon and the interaction between each of the three race components, the identification of target split times that can be used to inform the design of training plans and race pacing strategies is a complex task. The present study uses machine learning techniques to analyse a large database of performances in Olympic distance triathlons (2008–2012). The analysis reveals patterns of performance in five components of triathlon (three race “legs” and two transitions) and the complex relationships between performance in each component and overall performance in a race. The results provide three perspectives on the relationship between performance in each component of triathlon and the final placing in a race. These perspectives allow the identification of target split times that are required to achieve a certain final place in a race and the opportunity to make evidence-based decisions about race tactics in order to optimise performance.

Corporate social responsibility programs of big food in Australia: a content analysis of industry documents

OBJECTIVE: To examine Corporate Social Responsibility (CSR) tactics by identifying the key characteristics of CSR strategies as described in the corporate documents of selected 'Big Food' companies. METHODS: A mixed methods content analysis was used to analyse the information contained on Australian Big Food company websites. Data sources included company CSR reports and web-based content that related to CSR initiatives employed in Australia. RESULTS: A total of 256 CSR activities were identified across six organisations. Of these, the majority related to the categories of environment (30.5%), responsibility to consumers (25.0%) or community (19.5%). CONCLUSIONS: Big Food companies appear to be using CSR activities to: 1) build brand image through initiatives associated with the environment and responsibility to consumers; 2) target parents and children through community activities; and 3) align themselves with respected organisations and events in an effort to transfer their positive image attributes to their own brands. IMPLICATIONS: Results highlight the type of CSR strategies Big Food companies are employing. These findings serve as a guide to mapping and monitoring CSR as a specific form of marketing.

Supporting culturally and linguistically diverse students during clinical placement: strategies from both sides of the table

Background: Increasing proportions of Culturally and Linguistically Diverse (CALD) students within health professional courses at universities creates challenges in delivering inclusive training and education. Clinical placements are a core component of most health care degrees as they allow for applied learning opportunities. A research gap has been identified in regard to understanding challenges and strategies for CALD students in health professional placements.

Methods: A key stakeholder approach was used to examine barriers and enablers experienced by CALD students in clinical placement. Semi-structured focus groups with healthcare students (n = 13) and clinical placement supervisors (n = 12) were employed. The focus groups were analysed using open coding and thematic analysis.

Results: Three main barrier areas were identified: placement planning and preparation; teaching, assessment and feedback; and cultural and language issues. Potential solutions included addressing placement planning and preparation barriers, appropriate student placement preparation, pre-placement identification of higher risk CALD students, and diversity training for supervisors. For the barrier of teaching, assessment & feedback, addressing strategies were to: adapt student caseloads, encourage regular casual supervisor-student conversations, develop supportive placement delivery modes and structures, set expectations early, model the constructive feedback process, use visual aids, and tailor the learning environment to individual student needs. The enablers for cultural & language issues were to: build language and practical approaches for communication, raise awareness of the healthcare system (how it interacts with healthcare professions and how patients access it), and initiate mentoring programs.

Conclusions: The findings suggest that teaching and learning strategies should be student-centred, aiming to promote awareness of difference and its impacts then develop appropriate responses by both student and teacher. Universities and partnering agencies, such as clinical training providers, need to provide an inclusive learning environment for students from multiple cultural backgrounds.

Agriculture, trade openness and emissions: an empirical analysis and policy options

This article investigates the impact of sectoral production allocation, energy usage patterns and trade openness on pollutant emissions in a panel consisting of high-, medium- and low-income countries. Extended STIRPAT (Stochastic Impact by Regression on Population, Affluence and Technology) and EKC (Environmental Kuznets Curve) models are conducted to systematically identify these factors driving CO2 emissions in these countries during the period 1980–2010. To this end, the studyemploys three different heterogeneous, dynamic mean group-type linear panel modelsand one nonlinear panel data estimation procedure that allows for cross-sectionaldependence. While affluence, nonrenewable energy consumption and energy intensity variables are found to drive pollutant emissions in linear models, population is also found to be a significant driver in the nonlinear model. Both service sector and agricultural value-added levels play a significant role in reducing pollution levels, whereas industrialisation increases pollution levels. Although the linear model fails totrack any significant impact of trade openness, the nonlinear model finds trade liberalisation to significantly affect emission reduction levels. All of these results suggest that economic development, and especially industrialisation strategies and environmental policies, need to be coordinated to play a greater role in emission reduction due to trade liberalisation.

Translating person-centered care into practice: a comparative analysis of motivational interviewing, illness-integration support, and guided self-determination

OBJECTIVE: Person-centred care [PCC] can engage people in living well with a chronic condition. However, translating PCC into practice is challenging. We aimed to compare the translational potentials of three approaches: motivational interviewing [MI], illness integration support [IIS] and guided self-determination [GSD]. METHODS: Comparative analysis included eight components: (1) philosophical origin; (2) development in original clinical setting; (3) theoretical underpinnings; (4) overarching goal and supportive processes; (5) general principles, strategies or tools for engaging peoples; (6) health care professionals' background and training; (7) fidelity assessment; (8) reported effects. RESULTS: Although all approaches promoted autonomous motivation, they differed in other ways. Their original settings explain why IIS and GSD strive for life-illness integration, whereas MI focuses on managing ambivalence. IIS and GSD were based on grounded theories, and MI was intuitively developed. All apply processes and strategies to advance professionals' communication skills and engagement; GSD includes context-specific reflection sheets. All offer training programs; MI and GSD include fidelity tools. CONCLUSION: Each approach has a primary application: MI, when ambivalence threatens positive change; IIS, when integrating newly diagnosed chronic conditions; and GSD, when problem solving is difficult, or deadlocked. PRACTICE IMPLICATIONS: Professionals must critically consider the context in their choice of approach.

Response to Islamophobia in the Arabic Islamic discourse: a critical discourse analysis

In the aftermath of September 11, Muslim scholars made numerous attempts to explain Islamophobia from the Islamic perspective; they presented arguments that are not addressed in the Western narrative. Two texts in Arabic by the prominent Muslim preacher, Mohammad Hassan and by the Muslim orator Fadhel Sliman are analysed from a Critical Discourse Analysis (CDA) viewpoint. This analysis aims to demonstrate how language is inextricably linked with ideology. This paper demonstrates that textual strategies in the Arabic Islamic discourse and their ideological implications show distinct characteristics some of which add to the present literature on discourse. The aim of the chosen texts is to educate and create solidarity between the speakers and the audience in fighting Islamophobia. The reliance of the speakers on tactics such as quoting from the Holy Qur’ān and ḥadīth to defend Islam, and choice of words and sentence structures may instigate discussions about the persuasive power of the Arabic Islamic narrative.

Single session web-based counselling: a thematic analysis of content from the perspective of the client

Despite the exponential growth of non-appointment-based web counselling, there is limited information on what happens in a single session intervention. This exploratory study, involving a thematic analysis of 85 counselling transcripts of people seeking help for problem gambling, aimed to describe the presentation and content of online conversations. Observed from the perspective of the client, we found that presentations were related to immediate help with a crisis and non-urgent assistance in developing strategies and skills. Almost all clients spent a great deal of time telling their story (i.e., the pattern, context, progression and impact of the problem, motivation for continuing and previous attempts to change) with less time spent exploring opportunities, readiness or self-efficacy related to change or relevant options and strategies. These findings provide important information that informs the application of traditional counselling approaches within web-based environments.

Rationale for the use of DC microgrids: feasibility, efficiency and protection analysis

Electrical power systems are undergoing highly significant changes in their structures. The emergence of renewable energy units in the power generation sector, the use of high-voltage DC in the power transmission sector, and the prevalence of islanded or integrated microgrids in the distribution sector are the strongest evidence supporting this claim. These changes are mostly the consequences of the increasing energy demand rate, climate change, and environmental challenges, as well as the high investment and maintenance cost of the previous structures. Considering these new conditions and according to the recent development in DC/DC conversion topologies and control techniques, different studies have been conducted on how and why DC microgrids outperform AC microgrids. This study discusses the feasibility of the DC microgrid system according to recent developments in power systems. The efficiency and power loss reduction in DC distribution systems are then analyzed, some of the common strategies and devices for protection systems in such networks are reviewed, and the possible and existing challenges in developing the DC microgrids are highlighted. The mathematical calculations and theories for this evaluation are presented to determine the reliable justification for selecting the appropriate microgrid systems.

The influence of market orientation on innovation strategies

Purpose – The purpose of this paper is to examine the effects of market orientation on exploratory and exploitative innovation, and the moderating effects of family ownership on these relationships. Design/methodology/approach – This study utilizes multi-group path analysis and confirmatory factor analysis in LISREL on data from 228 firms in the Australian service sector. Findings – This study establishes that both customer and competitor innovation are positively related to exploitative and exploratory innovation. However, customer orientation does not lead to significantly stronger effects on exploitative innovation than on exploratory innovation, and competitor orientation does not lead to significantly stronger effects on exploratory innovation than on exploitative innovation. In addition, the study found that the relationship between customer orientation and exploratory innovation was stronger for family firms, while the relationships between competitor orientation and both exploratory and exploitative innovation were stronger for non-family firms. Research limitations/implications – The cross-sectional design is one weakness of this study. In addition, as firms in the present study came from the service sector the generalizability of the findings to other sectors of the economy need to be determined. Practical implications – These findings of this study highlight the need for managers to build a strong market orientation in order to promote innovation, and consider the effects of ownership structure on innovation strategies. Originality/value – This study is the first to measure the relative influence of customer and competitor orientation on a firm’s use of exploitative and exploratory innovation strategies.

Automated analysis of performance and energy consumption for cloud applications

In cloud environments, IT solutions are delivered to users via shared infrastructure. One consequence of this model is that large cloud data centres consume large amounts of energy and produce significant carbon footprints. A key objective of cloud providers is thus to develop resource provisioning and management solutions at minimum energy consumption while still guaranteeing Service Level Agreements (SLAs). However, a thorough understanding of both system performance and energy consumption patterns in complex cloud systems is imperative to achieve a balance of energy efficiency and acceptable performance. In this paper, we present StressCloud, a performance and energy consumption analysis tool for cloud systems. StressCloud can automatically generate load tests and profile system performance and energy consumption data. Using StressCloud, we have conducted extensive experiments to profile and analyse system performance and energy consumption with different types and mixes of runtime tasks. We collected finegrained energy consumption and performance data with different resource allocation strategies, system configurations and workloads. The experimental results show the correlation coefficients of energy consumption, system resource allocation strategies and workload, as well as the performance of the cloud applications. Our results can be used to guide the design and deployment of cloud applications to balance energy and performance requirements.

Effectiveness, costs, and cost-effectiveness of recruitment strategies for a mammographic screening program to detect breast cancer

BACKGROUND AND PURPOSE: Since effective and affordable recruitment methods are essential for the widespread implementation of mammographic screening for detection of breast cancer, we studied the effectiveness, the costs, and the cost-effectiveness of various recruitment strategies in the population targeted by a pilot Australian program that offered free mammography screening between 1988 and 1990. METHODS: We evaluated three public recruitment strategies--local newspaper articles, community promotion, and promotion to physicians--and five personal strategies--invitation letters with or without specified appointment times, either alone or with a follow-up letter, or telephone call to nonattenders. The effectiveness of public recruitment strategies was estimated from monthly attendance rates by Poisson regression analysis, while the probability of attendance in response to personal strategies was calculated using logistic regression analysis. Costs were determined by resource usage studies. The cost-effectiveness ratios for personal strategies were determined using decision analysis. RESULTS: The costs in 1988-1989 Australian dollars per woman recruited were $22 for local newspaper articles and $106 for community promotion. No detectable increase in attendance resulted from promotion to physicians. When the cost of reserving an appointment was considered, the most cost-effective personal recruitment strategy was an invitation letter without a specified appointment time, followed by a second letter to nonattenders. This strategy recruited 35.6% of women in the sample targeted and cost $10.52 per attendee. In comparison, the most effective personal recruitment strategy was a letter with a specified appointment time followed by a second letter to nonattenders, which recruited 44.1% of women at an average cost of $19.99 and a marginal cost of $59.71 per additional attendee. CONCLUSIONS: Personal recruitment strategies were more cost-effective than public strategies. The most cost-effective personal strategy was an invitation letter without a specified appointment time, followed by a second letter to nonattenders.
