Winner, Loser, or Innocent Victim? Has Renewable Energy Performed As Expected?

This study provides an evaluation of the performance of five renewable energy technologies used to generate electricity: biomass, geothermal, solar photovoltaics, solar thermal, and wind. The authors compared the actual performance of these technologies against stated projections that helped shape public policy goals over the last three decades. Their findings document a significant difference between the success of renewable technologies in penetrating the U.S. electricity generation market and in meeting cost-related goals, when compared with historic projections. In general, renewable technologies have failed to meet expectations with respect to market penetration. They have succeeded, however, in meeting or exceeding expectations with respect to their cost. To a significant degree, the difference in performance in meeting projections of penetration and cost stem from the declining price of conventional generation, which constitutes a moving baseline against which renewable technologies have had to compete.

A collaborative approach to adopting/adapting guidelines - the Australian 24-hour Movement Guidelines for the early years (birth to 5 years): an integration of physical activity, sedentary behavior, and sleep

BACKGROUND: In 2017, the Australian Government funded the update of the National Physical Activity Recommendations for Children 0-5 years, with the intention that they be an integration of movement behaviours across the 24-h period. The benefit for Australia was that it could leverage research in Canada in the development of their 24-h guidelines for the early years. Concurrently, the Grading of Recommendations Assessment, Development and Evaluation (GRADE) working group published a model to produce guidelines based on adoption, adaption and/or de novo development using the GRADE evidence-to-decision framework. Referred to as the GRADE-ADOLOPMENT approach, it allows guideline developers to follow a structured and transparent process in a more efficient manner, potentially avoiding the need to unnecessarily repeat costly tasks such as conducting systematic reviews. The purpose of this paper is to outline the process and outcomes for adapting the Canadian 24-Hour Movement Guidelines for the Early Years to develop the Australian 24-Hour Movement Guidelines for the Early Years guided by the GRADE-ADOLOPMENT framework. METHODS: The development process was guided by the GRADE-ADOLOPMENT approach. A Leadership Group and Consensus Panel were formed and existing credible guidelines identified. The draft Canadian 24-h integrated movement guidelines for the early years best met the criteria established by the Panel. These were evaluated based on the evidence in the GRADE tables, summaries of findings tables and draft recommendations from the Canadian Draft Guidelines. Updates to each of the Canadian systematic reviews were conducted and the Consensus Panel reviewed the evidence for each behaviour separately and made a decision to adopt or adapt the Canadian recommendations for each behaviour or create de novo recommendations. An online survey was then conducted (n = 302) along with five focus groups (n = 30) and five key informant interviews (n = 5) to obtain feedback from stakeholders on the draft guidelines. RESULTS: Based on the evidence from the Canadian systematic reviews and the updated systematic reviews in Australia, the Consensus Panel agreed to adopt the Canadian recommendations and, apart from some minor changes to the wording of good practice statements, keep the wording of the guidelines, preamble and title of the Canadian Guidelines. The Australian Guidelines provide evidence-informed recommendations for a healthy day (24-h), integrating physical activity, sedentary behaviour (including limits to screen time), and sleep for infants (<1 year), toddlers (1-2 years) and preschoolers (3-5 years). CONCLUSIONS: To our knowledge, this is only the second time the GRADE-ADOLOPMENT approach has been used. Following this approach, the judgments of the Australian Consensus Panel did not differ sufficiently to change the directions and strength of the recommendations and as such, the Canadian recommendations were adopted with very minor alterations. This allowed the Guidelines to be developed much faster and at lower cost. As such, we would recommend the GRADE-ADOLOPMENT approach, especially if a credible set of guidelines, with all supporting materials and developed using a transparent process, is available. Other countries may consider using this approach when developing and/or revising national movement guidelines

Modern technology allows the user to explore and interact with the virtual environment, offering opportunities for rehabilitation. The use of immersive VR in the management of musculoskeletal shoulder pain is relatively new and research is required to demonstrate its feasibility and effectiveness in this field. Aim: The aims of this study were, firstly, to explore physiotherapists’ beliefs and perspectives of immersive VR as a platform for rehabilitation in patients with musculoskeletal shoulder pain, secondly, to identify potential barriers and facilitators to using VR in a musculoskeletal setting and thirdly, to gain insight from clinicians that would inform the development of a VR intervention for the rehabilitation of musculoskeletal shoulder pain. Methods: This study used qualitative descriptive design methodology. A series of three focus group interviews were carried out, via Microsoft Teams. Physiotherapists received an Oculus Quest™ headset to use at home prior to the focus group interviews. A six-phase process of reflexive thematic analysis was carried out to identify themes within the data. Atlas Ti Qualitative Data Analysis software was used to facilitate thematic analysis. Results: Five themes were identified within the data. They reflected physiotherapists beliefs that VR provides novel opportunities for shoulder rehabilitation and may offer new avenues for managing movement-related fear and improving concordance with rehabilitation. However, barriers related to safety and practical considerations associated with using VR were also identified in the final themes. Conclusion: These findings provide valuable insight into clinician acceptability of immersive VR as a platform for rehabilitation and the need for further research to answer the questions posed by physiotherapists in the current study. This research will contribute to human-centered design of VR-supported interventions for managing musculoskeletal shoulder pain.Peer reviewe
