Pennsylvania's Bituminous Coal Industry: an Industry Review*
John N. Hoffman SMITHSONIAN INSTITUTION PENNSYLVANIA'S BITUMINOUS COAL INDUSTRY: AN INDUSTRY REVIEW* T HE BITUMINOUS coal field in Pennsylvania covers most of western lPennsylvania, extending from the southwest corner northward almost to Lake Erie, eastward to the Allegheny front, and northeast- ward through the north-central counties of the state to the southern boundary of New York. About 14,200 square miles are included in this field which forms the northeastern end of the Appalachian coal region, which in turn is a part of the eastern coal province. The boundary of the coal field is extremely irregular. On the north, the boundary runs from the northwest corner of Crawford County across Warren and McKean to Potter and Clinton counties, then extends as outlying patches into Tioga, Bradford, and Lycoming counties. From Clinton County, the boundary follows the Allegheny front southward through Centre County, and between Cambria and Blair, and Somerset and Bedford counties. East of this line lies the Broad Top field in Huntington, Bedford, and Blair counties lying about thirty miles east of the main field and covering an area of about fifty square miles. The coal measures are folded into many anticlines and synclines extending in a general northeast-southwest direction. The folding be- comes greater as it progresses eastward; so we find that the beds in the western portion of the state are only slightly folded and the sides dip slightly. The coal beds are of the Carboniferous Age (more than 250 million years old) and belong to the Pennsylvanian and Permian systems. The Pennsylvania system is again divided into the Monongahela, Cone- maugh, Allegheny, and Pottsville series, with the Permian system in- cluding the Dunkard series. -

ABSTRACT In North America and Europe, the Fall 2020 school term has coincided with the beginning of the second wave of the novel coronavirus (COVID-19) pandemic, sparking a heated debate about the role of in-person schooling for community transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This issue has immediate policy relevance for deciding how to operate schools safely as the pandemic unfolds, new variants of SARS-CoV-2 are circulating, and immuniZation coverage remains low. -

Canadian Planning Through a Transnational Lens: the Evolution of Urban Planning in Canada, 1890-1930
Canadian Planning through a Transnational Lens: the Evolution of Urban Planning in Canada, 1890-1930 Catherine Mary Ulmer A thesis submitted to McGill University in partial fulfillment of the requirements of the Degree of Doctor of Philosophy Fall 08 April 2017 Department of History and Classical Studies, Faculty of Arts, McGill University, Montreal © Catherine Mary Ulmer ii Abstract From the late nineteenth century onwards, a varied group of middle and upper class English- Canadians embraced urban planning, forming connections with the international planning cohort and circulating planning knowledge across Canada. Yet, despite their membership within the wider planning world, and the importance of such involvement to Canada’s early planning movement, the current historical narrative does not fully account for the complex nature of Canadian interactions with this wider planning cohort. This dissertation points to the necessity of applying a transnational perspective to our understanding of Canada’s modern planning history. It considers the importance of English-Canadian urban planning networking from 1910–1914, argues that these individuals were knowledgeable and selective borrowers of foreign planning information, and reassesses the role of Thomas Adams, the British expert who acted as a national planning advisor to Canada (1915–1922) and has been credited with founding Canada’s planning movement. Reevaluating his position, I argue that Adams did not introduce Canadians to modern planning. Instead his central role came through his efforts to help professionalize planning through creating the Town Planning Institute of Canada (TPIC) in 1919. As I assert, by restricting full membership to male professionals the TPIC relegated amateur planning advocates to a supporting role, devaluing the contributions of non-professionals, and, in particular, women. -

It was the opportunity for him to experience Chinese culture – the food, the landscape, the people and their dialects, even the smells in the air. It was also a reunion with my parents, time for me to take care of them so that my sister could have a break. When China started to lock down the city of Wuhan in January 2020, I worried about my family and friends in China, but I thought it would pass in a few months, like SARS some years ago. Unfortunately, I still cannot enter China with my Canadian passport. I immigrated to Canada almost 14 years ago and became a Canadian citizen in 2015. It has been a good decision, and I have successfully built my new life. -
Declarations of Independence Since 1776* DAVID ARMITAGE Harvard
South African Historical Journal, 52 (2005), 1-18 The Contagion of Sovereignty: Declarations of Independence since 1776* DAVID ARMITAGE Harvard University The great political fact of global history in the last 500 years is the emergence of a world of states from a world of empires. That fact – more than the expansion of democracy, more than nationalism, more than the language of rights, more even than globalisation – fundamentally defines the political universe we all inhabit. States have jurisdiction over every part of the Earth’s land surface, with the exception of Antarctica. The only states of exception – such as Guantánamo Bay – are the exceptions created by states.1 At least potentially, states also have jurisdiction over every inhabitant of the planet: to be a stateless person is to wander an inhospitable world in quest of a state’s protection. An increasing number of the states that make up that world have adopted democratic systems of representation and consultation, though many competing, even inconsistent, versions of democracy can exist beneath the carapace of the state.2 Groups that identify themselves as nations have consistently sought to realise their identities through assertions of statehood. The inhabitants of the resulting states have increasingly made their claims to representation and consultation in the language of rights. Globalisation has made possible the proliferation of the structures of democracy and of the language of rights just as it has helped to spread statehood around the world. Yet all of these developments – democratisation, nationalism, the diffusion of rights-talk and globalisation itself – have had to contend with the stubbornness of states as the basic datum of political existence. -
An Enhanced Approach for Economic Evaluation of Long-Term Benefits Of
nutrients Article An Enhanced Approach for Economic Evaluation of Long-Term Benefits of School-Based Health Promotion Programs John Paul Ekwaru *, Arto Ohinmaa and Paul J. Veugelers School of Public Health, University of Alberta, 3-50 University Terrace, 8303–112 St, Edmonton, AB T6G 2T4, Canada; [email protected] (A.O.); [email protected] (P.J.V.) * Correspondence: [email protected]; Tel.: +1-780-492-9095 Received: 31 March 2020; Accepted: 12 April 2020; Published: 16 April 2020 Abstract: Chronic diseases constitute a tremendous public health burden globally. Poor nutrition, inactive lifestyles, and obesity are established independent risk factors for chronic diseases. Public health decision-makers are in desperate need of effective and cost-effective programs that prevent chronic diseases. To date, most economic evaluations consider the effect of these programs on body weight, without considering their effects on other risk factors (nutrition and physical activity). We propose an economic evaluation approach that considers program effects on multiple risk factors rather than on a single risk factor. For demonstration, we developed an enhanced model that incorporates health promotion program effects on four risk factors (weight status, physical activity, and fruit and vegetable consumption). Relative to this enhanced model, a model that considered only the effect on weight status produced incremental cost-effectiveness ratio (ICER) estimates for quality-adjusted life years that were 1% to 43% higher, and ICER estimates for years with chronic disease prevented that were 1% to 26% higher. The corresponding estimates for return on investment were 1% to 20% lower. To avoid an underestimation of the economic benefits of chronic disease prevention programs, we recommend economic evaluations consider program effects on multiple risk factors.
