Development of a freely distributable CFD tool for approximate and detailed simulations of the flow around a complex of buildings

Indo-Swiss Building Energy Efficiency Project (BEEP) is a cooperation project between the Ministry of Power, Government of India, and the Federal Department of Foreign Affairs of the Swiss Confederation. Started in 2011, the project’s central focus is to help India mainstream Energy-Efficient and Thermally Comfortable (EETC) Building Design. BEEP works with building industry, policy makers, and building owners to catalyse adoption of EETC building design and technologies. India wants to avoid or reduce the use of air conditioning by improving natural ventilation at night, which requires numerical simulations to compute the flow around the buildings. However, the simulations of fluid flows are time consuming and are not used at the beginning of a project when the locations of the buildings are set. To improve the situation, a freely distributable environment based on the OpenFOAM toolbox has been developed providing two levels of resolution: an approximate level computing the flow in few minutes and a RANS level of simulation. The user inputs are limited to the geometry and the velocity direction and magnitude. The mesh and the numerical set up are automated. The accuracy of the two levels of resolution have been checked by computing test cases from the CEDVAL database.

Are human rights archives accessible? Challenges and possible solutions to improve access for Dealing with the Past initiatives

Records and archives containing information relating to grave violations of human rights and international humanitarian law represent a fundamental source for, and can become trustworthy documentary evidence within, Dealing with the Past (DWP) processes including truth commissions, criminal tribunals, reparation programs, vetting processes and outreach projects. Those intergovernmental organizations (IGOs) and international non-governmental organizations (INGOs) working in the fields of human rights and peace and security are themselves important observers and actors in DWP processes and hence their records and archives are highly relevant to DWP initiatives. Such organizations should therefore be transparent and be able to facilitate DWP processes by granting access to their records. Given the International Council on Archives’ definition of “access” as relating to “… the availability of records for consultation as a result both of legal authorization and the existence of finding aids”, and the experience of swisspeace in advising DWP initiatives on collecting evidence and improving records management capacity, swisspeace together with the Swiss Federal Department of Foreign Affairs developed a roadmap which centres on the development of an “archives accessibility maturity model”. This tool will not only improve hands-on access in practice, but will ultimately improve knowledge about the multi-layered complexity of archives’ accessibility, strengthening the capacity of IGOs, INGOs and DWP initiatives to design and implement their access regulations, and thereby improving DWP initiatives’ ability to make successful access requests.

Inlaws, Outlaws, and State Formation in Nineteenth-Century Oklahoma

While much of the federal Department of Justice’s policing bureaucracy was in retrenchment from the 1880s and 1890s, the Indian Territories was the site of some of the most aggressive policing in the nation’s history. Specifically, a series of reforms in US-Indian relations permitted a high level of federal involvement in policing and the management of local order. Using original demographic data on US deputy marshals and criminal gangs active in the Indian Territories, as well as an analysis of media coverage of Oklahoma crime, this article shows that this explosion of state-building was due, in part, to the ways in which kinship rules in Oklahoma allowed racially ambiguous inhabitants to be castigated as “outlaws.” This, in turn, opened up space for the federal marshal apparatus—which was primarily white—to expand its role as the purveyors of local law and order in a manner that had never been possible in the South.

New shadow professionals and infrastructures around the datafied school: Topological thinking as an analytical device

Drawing upon the growing datafication of contemporary schooling, our purpose in this article is to use topological thinking as an analytical device to better understand the professionals and practices within emergent data infrastructures. We address this by attending to an influential national (and subnational) data infrastructure of school monitoring in the United States, managed by the federal Department of Education, known as EDFacts. Informed by policy documents relating to EDFacts, as well as by various related software platforms and portals, we explore the whom and how of datafication, and expose the increasing presence and influence of otherwise ‘hidden’ technology mediators, or ‘shadow professionals’. In particular, we argue that the increasing dependency of EDFacts on data has necessitated the introduction of new professional roles associated with optimising the flow of data, and thus stabilising and normalising the topological space of the infrastructure. We conclude by suggesting that EDFacts encourages teaching professionals and shadow professionals alike to engage in acts of data submission; that is, providing data to EDFacts and, at the same time, positioning themselves as wholly responsive to the infrastructure and its datafied renderings of schooling.

The Effects of a Low Sodium Meal Plan on Blood Pressure in Older Adults: The SOTRUE Randomized Feasibility Trial

Reduced sodium meal plans are recommended by the Centers of Disease Control to lower blood pressure in older adults; however, this strategy has not been tested in a clinical trial. The Satter House Trial of Reduced Sodium Meals (SOTRUE) was an individual-level, double-blind, randomized controlled pilot study of adults living in a congregate living facility subsidized by the Federal Department of Housing and Urban Development (HUD). Adults over age 60 years ate 3 isocaloric meals with two snacks daily for 14 days. The meal plans differed in sodium density (<0.95 vs. >2 mg/kcal), but were equivalent in potassium and macronutrients. Seated systolic BP (SBP) was the primary outcome, while urine sodium-creatinine ratio was used to measure compliance. Twenty participants were randomized (95% women; 95% white; mean age 78 ± 8 years), beginning in 7 October 2019. Retention was 100% with the last participant ending 4 November 2019. Mean baseline SBP changed from 121 to 116 mmHg with the typical sodium diet (−5 mmHg; 95% CI: −18, 8) and from 123 to 112 mmHg with the low sodium diet (−11 mmHg; 95% CI: −15.2, −7.7). Compared to the typical sodium meal plan, the low sodium meal plan lowered SBP by 4.8 mmHg (95% CI: −14.4, 4.9; p = 0.31) and urine sodium-creatinine ratio by 36% (−36.0; 95% CI: −60.3, 3.4; p = 0.07), both non-significant. SOTRUE demonstrates the feasibility of sodium reduction in federally mandated meal plans. A longer and larger study is needed to establish the efficacy and safety of low sodium meals in older adults.

Beyond the COVID-19 crisis: building on lost opportunities in the history of public health

The influenza pandemic of 1918–1920, which killed 50 000 Canadians, spurred the creation of a federal department of public health. But in the intervening century, public health at all levels has remained, as Marc Lalonde put it in 1988, the “poor cousin” in the health care system ( Lalonde 1988 , p. 77). Punctuated by sporadic investment during infectious disease crises, such as polio in the early 1950s, public health is less of a priority as the cost of tertiary health interventions rises. While public health potentially involves a broad range of interventions, this paper focuses on the history of public health interventions around infectious disease. COVID-19 has forced us to relearn the importance of maintaining basic infectious/communicable disease control capacity and revealed the cost of our failure to do so. It has also drawn our attention to the intersection between social inequality, racism, and colonialism and vulnerability to disease. In addition to investing in our capacity to contain disease outbreaks as they occur, we must plan now for how to achieve greater health equity in the future by addressing underlying economic and social conditions and providing meaningful access to preventive care for all. This is how we build a truly resilient society. Governments at all levels have recognized the importance of social factors in shaping health and illness for decades. But greater health equity will result only from genuine action on this knowledge. Action will arise from public advocacy in support of prevention, and a new level of engagement and collaboration between affected individuals and communities, public health experts, and governments.

Practice of Preserving Collections in the Library and Archives Canada

The Library and Archives of Canada (LAC) is Federal department of Canada established by the Parliament of Canada in 2004 to integrate services and functions of the National library and the National Archives of Canada; and currently it is the fourth-largest library in the world. The article discusses the experience of the Library and Archives Canada in creating modern centres for preserving documentary heritage, organizing the work of collections management, their conservation and restoration, ensuring openness and accessibility of collections. The main sources were materials published on the LAC website, primarily planning, reporting and financial documentation of the institution, as well as publications in the Canadian periodical press. Special attention is paid to the buildings and premises of the LAC storage facilities. The author describes the concept of the project of the Gatineau Preservation Centre, GPC. The complex, opened in 1997, is one of the top architectural objects constructed in Canada in the 20th century and one of the most secure library storage facilities in the world. The article considers organization of collections storage in the GPC and the work of restoration laboratories located in it. The author shows that GPC provides the most favourable storage conditions for the most valuable and vulnerable LAC collections. The paper gives information about the storage facility in the main LAC building in Ottawa on Wellington Street (built in 1967; modernized in the early 2000s), as well as storage facilities in Gatineau, Renfrew and Winnipeg.The author characterizes the new version of the LAC Collections Preservation Program (2018) which defines the strategic objectives of the institution in this area, both for the nearest future and for the long term. The paper presents results of a large-scale study of the state of the collections storage in LAC (2016—2018) and outlines the most acute problems identified in this study. There is emphasized the importance of the construction of the new Gatineau-2 complex, launched in 2019 (Project cost is 330 million Canadian dollars). According to experts, Gatineau-2 will become one of the largest, technologically equipped and environmental centres for the conservation and restoration of library collections in the world, as well as the first zero-energy storage facility in North America. In Canada, special attention is paid to the construction of modern centres for the preservation of documentary heritage, which create all the necessary conditions for long-term security of collections, conservation and restoration work. Implementation of such projects is impossible without government support, without understanding by authorities of the leading role of libraries and archives in the preservation and promotion of the national cultural heritage. The experience of LAC may be of interest to Russia, taking into account the tasks set in the document “The main directions of development of activities to preserve library collections in the Russian Federation for 2011—2020” and elaboration of long-term programs in this area.

Application of Google Earth Engine Cloud Computing Platform, Sentinel Imagery, and Neural Networks for Crop Mapping in Canada

The ability of the Canadian agriculture sector to make better decisions and manage its operations more competitively in the long term is only as good as the information available to inform decision-making. At all levels of Government, a reliable flow of information between scientists, practitioners, policy-makers, and commodity groups is critical for developing and supporting agricultural policies and programs. Given the vastness and complexity of Canada’s agricultural regions, space-based remote sensing is one of the most reliable approaches to get detailed information describing the evolving state of the country’s environment. Agriculture and Agri-Food Canada (AAFC)—the Canadian federal department responsible for agriculture—produces the Annual Space-Based Crop Inventory (ACI) maps for Canada. These maps are valuable operational space-based remote sensing products which cover the agricultural land use and non-agricultural land cover found within Canada’s agricultural extent. Developing and implementing novel methods for improving these products are an ongoing priority of AAFC. Consequently, it is beneficial to implement advanced machine learning and big data processing methods along with open-access satellite imagery to effectively produce accurate ACI maps. In this study, for the first time, the Google Earth Engine (GEE) cloud computing platform was used along with an Artificial Neural Networks (ANN) algorithm and Sentinel-1, -2 images to produce an object-based ACI map for 2018. Furthermore, different limitations of the proposed method were discussed, and several suggestions were provided for future studies. The Overall Accuracy (OA) and Kappa Coefficient (KC) of the final 2018 ACI map using the proposed GEE cloud method were 77% and 0.74, respectively. Moreover, the average Producer Accuracy (PA) and User Accuracy (UA) for the 17 cropland classes were 79% and 77%, respectively. Although these levels of accuracies were slightly lower than those of the AAFC’s ACI map, this study demonstrated that the proposed cloud computing method should be investigated further because it was more efficient in terms of cost, time, computation, and automation.

Outpatient before inpatient—the good, the bad and the ugly

Summary Background In January 2019 the Swiss Federal Department of Home Affairs defined a group of six selected surgical interventions to be performed on an outpatient basis. The aim of this paper is to assess surgeons’ opinions on patient safety, costs and treatment based on this new regulation. Methods An online survey was sent electronically to all 942 members of the Swiss Society of Surgery between August and October 2019. Results About half of the participants think the new regulation could harm patients (52%) and will lead to lower patient satisfaction (49%). Whereas half of the participants expect a reduction in health care costs (52%), most expect surgeons to earn less due to the new regulation (82%). About three quarters (73%) of the participants expect the new regulation to negatively affect surgical resident education. More than half (62%) of the participants assume that diagnoses allowing reimbursement for inpatient treatment (such as, e.g., bilateral instead of unilateral inguinal hernia) could be made more generously. Accordingly, 70% assume that the new regulation may result in not necessarily indispensable or possibly unnecessarily extended interventions (such as, e.g., bilateral inguinal hernia repair). Furthermore, most (86%) participants fear that the new regulation could possibly lead to hospitals/surgeons rejecting patients. Conclusion Whereas about half of the participants expect a reduction in health care costs, about two thirds fear that more generous diagnoses and not necessarily indispensable or possibly unnecessarily extended interventions could be performed due to the new regulation demanding outpatient care for said surgical interventions.
