Developing and Verifying the Psychometric Integrity of the Certification Examination for Imaging Informatics Professionals

The American Board of Imaging Informatics (ABII) was founded in 2005 by the Society of Imaging Informatics in Medicine (SIIM) and the American Registry of Radiologic Technologists (ARRT). ABII’s mission is to enhance patient care, professionalism, and competence in imaging informatics. This is accomplished primarily through the development and administration of a certification examination. The creation of the exam has been an exercise in open community involvement with SIIM providing access to the PACS community and ARRT providing skilled psychometric support to ensure a balanced and comprehensive examination. The process to generate the exam required several years and the efforts of dozens of subject matter experts active who volunteered to submit and validate questions for the examination. This article describes the organizational and statistical processes used to generate test items, assemble test forms, set performance standards, and validate test scores

Climate change education for universities: a conceptual framework from an international study

The role of universities in climate change education (CCE) is of great importance if the scientific, social, environmental and political challenges the world faces are to be met. Future leaders must make decisions from an informed position and the public will need to embed climate change mitigation tools into their work and private life. It is therefore essential to understand the range of CCE strategies being taken globally by Higher Education Institutions (HEIs) and to explore and analyse the ways that HEIs could better address this challenge. Consistent with this research need, this paper offers an analysis of the extent to which HEIs in 45 countries approach CCE and provides a conceptual framework for exploring how HEIs are embedding CCE into their curricula. In addition to the specialist approach (where students choose to study a degree to become experts in climate change adaptation and mitigation tools), the CCE framework developed identifies and highlights three other approaches HEIs can deploy to embed CCE: Piggybacking, mainstreaming and connecting (transdisciplinary). Using data gathered in an explorative international survey involving participants working across academic and senior management, this paper illustrates the different approaches taken and analyses practical examples of current CCE practice from across the world. Responses from 212 university staff from 45 countries indicated that CCE was highly variable – no clear pattern was identified at the country level, with CCE approaches varying significantly, even within individual HEIs. This plurality highlights the wide range of ideas and examples being shared and used by institutions in very different countries and contexts, and underlines the importance of the independence and autonomy of HEIs so that they can choose the right CCE approaches for them. To highlight the breadth and variety of approaches that were uncovered by our survey, the paper offers a range of examples illustrating how climate change education may be embedded in a higher education context, some of which could be replicated in HEIs across the world. The conceptualisation of CCE and the examples given in this paper are valuable for anyone who is thinking about strategies for embedding more climate education in the higher education curriculum

Climate vulnerability, impacts and adaptation in Central and South America coastal areas

© 2019 Elsevier B.V. Low-Elevation Coastal Zones in Central and South America are exposed to climate-related hazards (sea-level rise, climate variability and storms) which threaten the assets (people, resources, ecosystems, infrastructure, and the services they provide), and are expected to increase due to climate change. A non-systematic review is presented focusing on vulnerability elements, impacts, constraints to adaptation, and their possible strategies. The analysis emphasises the Intergovernmental Panel on Climate Change Reasons for Concern (e.g., threatened systems, extreme events, aggregated impacts, and critical thresholds), particularly on sea-level rise, degradation of mangroves, and invasive alien species in Central and South America focusing on case studies from Uruguay and Venezuela. Despite recent advances in coastal adaptation planning in Central and South America, there is an adaptation deficit in the implementation of measures and strategies against climate-related hazards, such as sea-level rise. Adaptation constraints are linked with poverty, resource allocation, lack of political will, and lack of early warning systems for climate-related hazards. Non-structural adaptation measures such as community-based adaptation and ecosystem-based adaptation are not fully mainstreamed into national plans yet. Government-level initiatives (e.g. National Adaptation Programmes of Action) are being developed, but a few are already implemented. In addition to specific thematic measures, the implementation of non-structural approaches, National Adaptation Programmes of Action and early warning systems, based on the reasons for concern, should foster adaptive capacity in coastal areas

An assessment of the relationships between extreme weather events, vulnerability, and the impacts on human wellbeing in Latin America

Climate change and variability are known to have an influence on human wellbeing in a variety of ways. In Latin America, such forces are especially conspicuous, particularly in respect of extreme climatological, hydrological, and weather events (EWEs) and climate-sensitive disasters (CSDs). Consistent with the need to study further such connections, this paper presents an analysis of some of the vulnerabilities of environmental health issues and climate-related impacts that are focusing on EWEs and CSDs in Latin American countries. The research includes an analysis of the (i) human and socio-economic development; (ii) geographical and socio-economic determinants of vulnerability and adaptability of environmental health issues (exposure, sensitivity, and adaptive capacity); (iii) occurrence of CSDs from 1988 to 2017 and their direct impacts on human wellbeing (Total death and Affected people); (iv) an online survey on the perceptions of the effects of EWEs on human wellbeing in a sample of countries in the region; and (v) discussion of possible solutions. The socio-economic and development indices, and the International Disaster Database (EM-DAT) and Climate-Risk Index (CRI) disaster statistics suggest that the impacts of CSDs are primarily related to socio-economic determinants of human wellbeing and health inequalities. Also, >80% respondents to the survey say that the leading causes of climate-related human impacts are the lack of (i) public awareness; (ii) investment and (iii) preparedness. The paper concludes by adding some suggestions that show how countries in Latin America may better cope with the impacts of Climate-sensitive Disasters

Climate change scepticism at universities: a global study

Scepticism about climate change is still a popular trend, despite the existence of scientific evidence that this phenomenon is taking place, and that it is influencing the lives of millions of people around the world. The aim of this paper is to assess the extent to which existing scepticism at the university level is found. The methodology consists of a survey undertaken on a sample of universities around the world, in the context of which attitudes and perceptions about climate change are identified. A total of 237 questionnaires were received from 51 countries around the world. The analysis consists basically of descriptive statistics and an investigation regarding trends on scepticism and the geographical location of the universities. The study concludes by outlining some of the presently seen scepticisms and suggests some ways to address them via curricular innovation and initiatives engaging students

Climate change and health: An analysis of causal relations on the spread of vector-borne diseases in Brazil

The increases in greenhouse gas concentrations caused by anthropogenic activities such as industrial emissions, transport and burning of forests and other resources, recorded over the past decades, are known to have an impact on the global environment. In particular, this paper reviews the evidence that climate change has an impact on human health as a whole and on the spread of vector-borne diseases in particular. It offers an analysis of previous research on the connections between climate change and health, with a case study from Brazil, and lists some areas which may guide future policy-making

Treatment response and remission in a double-blind, randomized, head-to-head study of lisdexamfetamine dimesylate and atomoxetine in children and adolescents with attention-deficit hyperactivity disorder

The Author(s) 2014. This article is published with open access at Springerlink.com Objectives A secondary objective of this head-to-head study of lisdexamfetamine dimesylate (LDX) and ato-moxetine (ATX) was to assess treatment response rates in children and adolescents with attention-deficit hyperactiv-ity disorder (ADHD) and an inadequate response to methylphenidate (MPH). The primary efficacy and safety outcomes of the study, SPD489-317 (ClinicalTrials.gov NCT01106430), have been published previously. Methods In this 9-week, double-blind, active-controlled study, patients aged 6–17 years with a previous inadequate response to MPH were randomized (1:1) to dose-optimized LDX (30, 50 or 70 mg/day) or ATX (patients \70 kg: 0.5–1.2 mg/kg/day, not to exceed 1.4 mg/kg/day; patients C70 kg: 40, 80 or 100 mg/day). Treatment response was a secondary efficacy outcome and was predefined as a reduction from baseline in ADHD Rating Scale IV (ADHD-RS-IV) total score of at least 25, 30 or 50 %. Sustained response was predefined as a reduction from baseline in ADHD-RS-IV total score (C25, C30 or C50 %) or a Clinical Global Impressions (CGI)–Improvement (CGI–I) score of 1 or 2 throughout weeks 4–9. CGI– Severity (CGI–S) scores were also assessed, as an indicator of remission. Results A total of 267 patients were enrolled (LDX, n = 133; ATX, n = 134) and 200 completed the study (LDX, n = 99; ATX, n = 101). By week 9, significantly (p \ 0.01) greater proportions of patients receiving LDX than ATX met the response criteria of a reduction from baseline in ADHD-RS-IV total score of at least 25 % (90.5 vs. 76.7 %), 30 % (88.1 vs. 73.7 %) or 50 % (73.0 vs. 50.4 %). Sustained response rates were also signifi-cantly (p \ 0.05) higher among LDX-treated patient

The Influence of the Corona Virus Pandemic on Sustainable Development Goal 13 and United Nations Framework Convention on Climate Change Processes

Apart from many social and economic problems worldwide, the COVID-19 pandemic has also led to sudden halt in face-to-face climate-related meetings. Moreover, it has also negatively influenced the works related to the preparations for the sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) and organizing the 26th Conference of the Parties of the UN Framework Convention on Climate Change (UNFCCC), namely COP26 to be held in Glasgow, which was postponed to November 2021. This article presents a global study undertaken among UNFCCC contact points and other climate experts, to ascertain the impacts of the pandemic on the implementation of SDG13 and UNFCCC processes. The methodological approach entails an bibliometric analysis, online survey, and authors’ expert judgment. Results of the bibliometric analysis show that the most common terms associated with this theme are COVID-19, climate change, CO2, energy, “pandemic-related,” and “adaptation-related.” In addition, the survey revealed some difficulties associated with online participation in the processes from many developing countries. The study concluded that there is negative impact of COVID-19 pandemic on the UNFCCC process, more minor government priorities regarding climate action, loss of traction of the process, and a challenge to achieve the Paris Agreement, with less significant support from the respondents from less developed countries. The findings suggest that urgent action is needed, to make up for the lost time, and place climate issues more prominently on the global agenda
