Animal Agriculture in a Changing Climate Online Course: An Effective Tool for Creating Extension Competency

There is a need to create competency among Extension professionals on the topic of climate change adaptation and mitigation in animal agriculture. The Animal Agriculture in a Changing Climate online course provides an easily accessible, user-friendly, free, and interactive experience for learning science-based information on a national and regional level. The web-based curriculum is proving to be a useful tool and valuable resource for Extension educators in gaining knowledge and being better equipped to inform and influence livestock and poultry producers regarding climate issues

Building Capacity within Extension to Address Animal Agriculture in a Changing Climate

The Animal Agriculture in a Changing Climate project was formed to build capacity among Extension professionals and other livestock advisors to address climate change issues. We offer a case study of how a small team can build national capacity for new topics. We used a coordinated multiregional approach to leverage national efforts applied to locally relevant climatology, production systems, and climate issues. Key insights on overcoming challenges centered on (a) engaging audiences with local, historical trends and agricultural impacts, (b) beginning with adaptation, rather than mitigation of climate change, and (c) providing strategies for effectively communicating science during controversy. Program participants found the project valuable and substantially increased their ability and motivation to apply climate science

Large expert-curated database for benchmarking document similarity detection in biomedical literature search

Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency–Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research

Home and Online Management and Evaluation of Blood Pressure (HOME BP) using a digital intervention in poorly controlled hypertension: randomised controlled trial

Objective: The HOME BP (Home and Online Management and Evaluation of Blood Pressure) trial aimed to test a digital intervention for hypertension management in primary care by combining self-monitoring of blood pressure with guided self-management. Design: Unmasked randomised controlled trial with automated ascertainment of primary endpoint. Setting: 76 general practices in the United Kingdom. Participants: 622 people with treated but poorly controlled hypertension (>140/90 mm Hg) and access to the internet. Interventions: Participants were randomised by using a minimisation algorithm to self-monitoring of blood pressure with a digital intervention (305 participants) or usual care (routine hypertension care, with appointments and drug changes made at the discretion of the general practitioner; 317 participants). The digital intervention provided feedback of blood pressure results to patients and professionals with optional lifestyle advice and motivational support. Target blood pressure for hypertension, diabetes, and people aged 80 or older followed UK national guidelines. Main outcome measures: The primary outcome was the difference in systolic blood pressure (mean of second and third readings) after one year, adjusted for baseline blood pressure, blood pressure target, age, and practice, with multiple imputation for missing values. Results: After one year, data were available from 552 participants (88.6%) with imputation for the remaining 70 participants (11.4%). Mean blood pressure dropped from 151.7/86.4 to 138.4/80.2 mm Hg in the intervention group and from 151.6/85.3 to 141.8/79.8 mm Hg in the usual care group, giving a mean difference in systolic blood pressure of −3.4 mm Hg (95% confidence interval −6.1 to −0.8 mm Hg) and a mean difference in diastolic blood pressure of −0.5 mm Hg (−1.9 to 0.9 mm Hg). Results were comparable in the complete case analysis and adverse effects were similar between groups. Within trial costs showed an incremental cost effectiveness ratio of £11 ($15, €12; 95% confidence interval £6 to £29) per mm Hg reduction. Conclusions: The HOME BP digital intervention for the management of hypertension by using self-monitored blood pressure led to better control of systolic blood pressure after one year than usual care, with low incremental costs. Implementation in primary care will require integration into clinical workflows and consideration of people who are digitally excluded. Trial registration: ISRCTN13790648

Is it weather or is it climate?

The difference between weather and climate is the time scale over which the conditions are described

Mean 1961-1990 Temperature and Precipitation Over the Upper Midwest

Several years ago, mean charts of temperature and precipitation were prepared for the upper Midwest by the North Central Regional Climate Center, based on 1951-1980 data (Wendland et al., 1985). Since the World Meteorological Organization and the U.S. National Weather Service (NWS) recommend updating 30-year averages each decade for the construction of climatic mean (normal) values, the following analyses are presented for 1961-1990 data for the nine states included in the region of the Midwestern Climate Center. The data used for the analysis are observations from NWS Offices and Forecast Offices, as well as NWS Cooperative sites, acquired from the Midwest Climate Information System, located at the Illinois State Water Survey, Champaign. Data density varied upwards from about 60 stations per state.published or submitted for publicationis peer reviewe
