Prioritizing Key Resilience Indicators to Support Coral Reef Management in a Changing Climate

Managing coral reefs for resilience to climate change is a popular concept but has been difficult to implement because the empirical scientific evidence has either not been evaluated or is sometimes unsupportive of theory, which leads to uncertainty when considering methods and identifying priority reefs. We asked experts and reviewed the scientific literature for guidance on the multiple physical and biological factors that affect the ability of coral reefs to resist and recover from climate disturbance. Eleven key factors to inform decisions based on scaling scientific evidence and the achievability of quantifying the factors were identified. Factors important to resistance and recovery, which are important components of resilience, were not strongly related, and should be assessed independently. The abundance of resistant (heat-tolerant) coral species and past temperature variability were perceived to provide the greatest resistance to climate change, while coral recruitment rates, and macroalgae abundance were most influential in the recovery process. Based on the 11 key factors, we tested an evidence-based framework for climate change resilience in an Indonesian marine protected area. The results suggest our evidence-weighted framework improved upon existing un-weighted methods in terms of characterizing resilience and distinguishing priority sites. The evaluation supports the concept that, despite high ecological complexity, relatively few strong variables can be important in influencing ecosystem dynamics. This is the first rigorous assessment of factors promoting coral reef resilience based on their perceived importance, empirical evidence, and feasibility of measurement. There were few differences between scientists\u27 perceptions of factor importance and the scientific evidence found in journal publications but more before and after impact studies will be required to fully test the validity of all the factors. The methods here will increase the feasibility and defensibility of including key resilience metrics in evaluations of coral reefs, as well as reduce costs.

Mathematics, statistics and archaeometry: the past 50 years or so

This review of developments in the use of mathematics and statistics in archaeometry over the past 50 years is partial, personal and 'broad-brush'. The view is expressed that it is in the past 30 years or so that the major developments have taken place. The view is also expressed that, with the exception of methods for analysing radiocarbon dates and increased computational power, mathematical and statistical methods that are currently used, and found to be useful in widespread areas of application such as provenance studies, don't differ fundamentally from what was being done 30 years ago

Local communities and sport activities expenditures and image: residents’ role in sustainable tourism and recreation

The practice of sports by resident communities is a tool for healthy lifestyles, inclusive growth and the promotion of sustainable cities. Nevertheless, the relationship between sport, tourism and recreation still remain an under researched theme. Focusing on the economic pillar of sustainability, this study intends to quantify and analyse the economic costs incurred by families in formal and informal sport practices, as well as the contribution of these activities and related events to the territory's image projection and attractiveness, by overlapping resident's and visitor's perception of sports in the destination. Applied to the municipality of Guimaraes (Portugal), this analysis of the sports consumer's behaviour contributes to filling the gap of knowledge resulting from the studies that, as a rule, exclusively evaluate the investments (supply) and/or the expenses (demand) of events and not the regular practice of sport. A total of 179 questionnaires were applied to residents throughout 2017, through the self-administrate questionnaire method. Findings reveal that residents see sports as one of the factors contributing to the identity of the municipality, underlying motivations for participation as the search for happiness, health, wellbeing, and fun. Expenditures generate multiplier effects in the local economy, allowing to compare growth scenarios. This analysis is a scientific instrument to support territorial innovation and the decision at the local level of public policies for sustainable development, in agreement with objective eight of sustainability defined by the United Nations.Funding Agency Municipality of Guimaraes/Sports Studies Centre of Guimaraesinfo:eu-repo/semantics/publishedVersio

Stroke treatment academic industry roundtable recommendations for individual data pooling analyses in stroke

Pooled analysis of individual patient data from stroke trials can deliver more precise estimates of treatment effect, enhance power to examine prespecified subgroups, and facilitate exploration of treatment-modifying influences. Analysis plans should be declared, and preferably published, before trial results are known. For pooling trials that used diverse analytic approaches, an ordinal analysis is favored, with justification for considering deaths and severe disability jointly. Because trial pooling is an incremental process, analyses should follow a sequential approach, with statistical adjustment for iterations. Updated analyses should be published when revised conclusions have a clinical implication. However, caution is recommended in declaring pooled findings that may prejudice ongoing trials, unless clinical implications are compelling. All contributing trial teams should contribute to leadership, data verification, and authorship of pooled analyses. Development work is needed to enable reliable inferences to be drawn about individual drug or device effects that contribute to a pooled analysis, versus a class effect, if the treatment strategy combines ≥2 such drugs or devices. Despite the practical challenges, pooled analyses are powerful and essential tools in interpreting clinical trial findings and advancing clinical care
