Experiencing Science, An Introduction to Real Methods of Science for the Preservice Teacher

The scientific method presented in the middle school classroom introduces the experimental approach of science in a way that may actually bear little resemblance to the processes actually used by working scientists. Teachers equipped with an insight into the motivations, philosophy, tools, and culture of science will better convey an accurate and positive picture of science as a critically important human endeavor. The Experiencing Science course was designed to answer the challenge of giving the pre-service teacher and decision-maker better insight into actual processes used by scientists, in the context of each of the major disciplines

Teaching Physical Science Through Technology: Middle School VCU PHY 591

Teaching Physical Science through Technology is a new 3-credit laboratory-and-lecture based course designed to serve as an introduction to the teaching of physical science concepts at the middle school level. Physical science phenomena are presented through investigations of commonly known applications of technology and focus on the Virginia Science Standards of Learning for 6th Grade Science and the Physical Science courses. Topics include matter, gravity, mechanics, heat, optics, electricity and magnetism, and computers as seen in their roles in common devices. The development of the course includes assessment from six semesters, collaboration with other institutions including the Science Museum of Virginia, and an 800 page text written by Adam Niculescu

Energy access for sustainable development

It is abundantly clear that adequate, reliable and clean energy services are vital for the achievement of many of the Sustainable Development Goals (SDGs). In essence, energy access has come to represent one of the intractable challenges in development, and therefore emblematic of the call for poverty eradication, and economic and social transformation. This focus issue on 'Energy Access for Sustainable Development' is initiated to draw broadly from the ideas and emerging experiences with energy activities and solutions that sought to enhance sustainable development through expansion of energy access. The focus issue includes several contributions from authors on some of the knowledge gaps this field, including: (i) the role of off-grid and mini-grid energy systems to meet multiple SDGs; (ii) the impacts of the evolving suite of off-grid and distributed energy services on inequalities across gender, and on minority and disadvantaged communities; (iii) the opportunities that the evolving technology base (both of energy services and information systems) plays in expanding the role of off-grid and mini-grid energy systems; (iv) energy options for cooking; (v) new insights into energy planning as well as the political economy, institutional and decision challenges across the energy system. Drawing from papers in this focus issue and other literature, this paper provides a sketch of the key issues in energy access

Prevalence of airflow limitation in outpatients with cardiovascular diseases in Japan.

Background and objectives: Cardiovascular disease (CVD) and chronic obstructive pulmonary disease (COPD) commonly coexist and share common risk factors. The prevalence of COPD in outpatients with a smoking history and CVD in Japan is unknown. The aim of this study was to determine the proportion of Japanese patients with a smoking history being treated for CVD who have concurrent airflow limitation compatible with COPD. A secondary objective was to test whether the usage of lung function tests performed in the clinic influenced the diagnosis rate of COPD in the patients identified with airflow limitation. Methods: In a multicenter observational prospective study conducted at 17 centers across Japan, the prevalence of airflow limitation compatible with COPD (defined as forced expiratory volume (FEV)1/FEV6 <0.73, by handheld spirometry) was investigated in cardiac outpatients ≥40 years old with a smoking history who routinely visited the clinic for their CVD. Each patient completed the COPD Assessment Test prior to spirometry testing. Results: Data were available for 995 patients with a mean age of 66.6±10.0 years, of whom 95.5% were male. The prevalence of airflow limitation compatible with COPD was 27.0% (n=269), and 87.7% of those patients (n=236) did not have a prior diagnosis of COPD. The prevalence of previously diagnosed airflow limitation was higher in sites with higher usage of lung function testing (14.0%, 15.2% respectively) compared against sites where it is performed seldom (11.1%), but was still low. Conclusion: The prevalence of airflow limitation in this study indicates that a quarter of outpatients with CVD have COPD, almost all of whom are undiagnosed. This suggests that it is important to look routinely for COPD in CVD outpatients

A Human-Centered Design Approach to Access to Justice: Generating New Prototypes and Hypotheses for Intervention to Make Courts User-Friendly

How can the court system be made more navigable and comprehensible to unrepresented laypeople trying to use it to solve their family, housing, debt, employment, or other life problems? This Article chronicles human-centered design work to generate solutions to this fundamental challenge of access to justice. It presents a new methodology: human-centered design research that can identify key opportunity areas for interventions, user requirements for interventions, and a shortlist of vetted ideas for interventions. This research presents both the methodology and these “design deliverables” based on work with California state courts’ Self Help Centers. It identifies seven key areas for courts to improve their usability, and, in each area, proposes a range of new interventions that emerged from the class’s design work. This research lays the groundwork for pilots and randomized control trials, with its proposed hypotheses and prototypes for new interventions, that can be piloted, evaluated, and — ideally — have a practical effect on how comprehensible, navigable, and efficient the civil court system is

The relationship between the COPD Assessment Test score and airflow limitation in Japan in patients aged over 40 years with a smoking history.

BACKGROUND: A large number of chronic obstructive pulmonary disease (COPD) patients in Japan remain undiagnosed, primarily due to the underuse of spirometry. Two studies were conducted to see whether the COPD Assessment Test (CAT) in primary care has the potential to identify those patients who need spirometry for a diagnosis of COPD and to determine whether patients with cardiovascular disease had airflow limitation, which could be detected by CAT. MATERIALS AND METHODS: Two multicenter, noninterventional, prospective studies (studies 1 and 2) were conducted across Japan. Patients in both studies were ≥40 years old with a smoking history. Those in study 1 were seen in primary care and had experienced repeated respiratory tract infections, but had no diagnosis of COPD. Patients in study 2 were identified in cardiovascular disease clinics when routinely visiting for their cardiovascular disease. All patients completed the CAT prior to lung-function testing by hand-held spirometry. The presence of airflow limitation was defined as a forced expiratory volume in 1 second (FEV1)/FEV6 ratio<0.73. RESULTS: A total of 3,062 subjects completed the CAT (2,067 in study 1, 995 in study 2); 88.8% were male, and the mean age (±standard deviation) was 61.5±11.6 years. Airflow limitation was found in 400 (19.4%) patients in study 1, and 269 (27.0%) in study 2. The CAT score in patients with airflow limitation was significantly higher than in patients without airflow limitation in both studies: 8.6 (95% confidence interval [CI] 7.9-9.2) versus 7.4 (95% CI 7.1-7.6) in study 1, and 8.3 (95% CI 7.5-9.2) versus 6.4 (95% CI 6.0-6.8) in study 2 (both P<0.001). CONCLUSION: These findings suggest that the CAT has the potential to identify patients with cardiovascular disease or a history of frequent chest infections who need spirometry to diagnose COPD
