Abstract:
During the late 19th and early 20th centuries, elderly individuals with severe mental illness living in the United States were cared for in state-run facilities that went by various names (asylums, psychopathic hospitals, state hospitals, state mental hospitals, and medical centers). Since the beginning of the 20th century, approximately 20% of patients in state hospital facilities had brain diseases such as dementia, usually complicated by behavioral disorder.

Abstract:
On several occasions in the early twentieth century, advocates of urban planning proposed significant measures for altering the layout of Toronto streets. Planning historians often have proposed that an interest in beautification was superseded by a focus on efficiency by the 1920s, but Toronto's plans largely were lost amidst private development processes and business cycles. Confusion over planning priorities, the short-term perspectives of politicians, and a lack of urgency also impeded city and regional planning. Toronto experienced less planning initiatives than major United-States cities.

Abstract This essay strives to bring together the institutional history of phenomenological psychology within the American academy from the middle of the 20th century to the current moment. Although phenomenological psychology has always been a dynamically international and interdisciplinary movement, the scope of this essay is limited to the different ways in which this new field expressed itself in certain psychology departments and educational institutions across the United States. After presenting this institutional history, and some (but certainly not all) individual contributors, a brief commentary is offered.

Abstract:
This paper is a brief stream of thought on the function of encampments in the United States during the 20th century. This work derives directly from my still-in-progress dissertation, “The Age of Encampment: Race, Surveillance, and the Power of Spatial Scripts, 19331950.” The dissertation charts a history of the creation of federally-funded camps and their lasting legacies beginning with the creation of New Deal-era liberal policies through the incarceration of enemies of the state during WWII. By revealing the history of federally-funded encampments in the US, I argue that camp spaces were racialized and classist projects dependent on a pathologized “other.” Further, the materialization of camp spaces became a tool used by the US government to surveille bodies deemed threatening to the local community and/or nation-state – a theory I call “spatial scripts.”

Abstract:
After an enormous spread in the United States of America during the 19th century homeopathy had almost completely vanished from the scene by the beginning of the 20th century. For the past two decades, however, it seems once again to experience a kind of renaissance. Major aspects of this development—in terms of medical and cultural history, sociology, politics, and economics—are illustrated on the basis of a general history of homeopathy in the United States. Using original sources, a first attempt is made to reconstruct the history of homeopathy in San Francisco which has some institutional peculiarities that make it unique within the whole country.

Abstract:
AbstractAlthough medical malpractice litigation in the United States has generated extensive professional and scholarly attention, few analyses of the issue have explored its underlying causes. This essay develops and employs an historical framework to explain the late 20th century phenomenon and concludes that widespread medical malpractice suits are the result of a combination of short-term topical causes and long-term cultural changes that are ignored or left untouched by most reform efforts. Most importantly, however, the development and proliferation of new and improved medical technologies has played a pivotal role throughout the entire history of the litigation, an effect that has become most prominent and important in the last third of the 20th century.

Abstract We re-examine the long-run geographical development of US manufacturing industries using recent advances in spatial concentration measures. We construct spatially weighted indices of the geographical concentration between 1880 and 2007 taking into account industrial structure and checkerboard problem. New results emerge. Average spatial concentration was much lower in the late 20th than in the late 19th century, and it was the outcome of a continuing reduction over time. Spatial concentration did not increase in the early 20th century but declined, and we find no inverted-U shape pattern of long-run spatial concentration. The persistent tendency to greater spatial dispersion was characteristic of most industries.

Relationships between religion and comics are generally unexplored in the academic literature. This article provides a brief history of Black religions in comic books, cartoons, animation, and newspaper strips, looking at African American Christianity, Islam, Africana (African diaspora) religions, and folk traditions such as Hoodoo and Conjure in the 20th century. Even though the treatment of Black religions in the comics was informed by stereotypical depictions of race and religion in United States (US) popular culture, African American comics creators contested these by offering alternatives in their treatment of Black religion themes.

Full text
Abstract:

This dissertation is a history of topical invention in U.S. rhetorical studies. Topical invention is the procedurally structured and/or organized thinking-out of propositions in text, speech, or other symbolic products; it is the structured and systematized method of invention originally developed by Aristotle, often referred to by the Greek topoi or the Latin loci. Although it goes by many names in recent history, topical invention has a structure based on Michael Leff’s definition of topical invention that shares five common aspects: data, claims or conclusions, linkages, sources, and topics. Data are some set of contextual knowledge, claims or conclusions are statements that express a truth value based on data, linkages are the expressed or implicit relationship between data and claims or conclusions, sources are methods for finding linkages, and topics are the naming of discrete entities in a system for invention.

This history selects texts dealing with topical invention in U.S. rhetorical studies discourse published between 1914 and 2014. A text was considered to be dealing with topical invention if it had an explicit discussion of topical invention or a discussion matching the structure of topical invention. U.S. rhetorical studies is the discourse community present in journals published by the four major United States professional societies studying rhetoric—the National Communication Association, the National Council of Teachers of English, the Rhetoric Society of America, and the American Society for the History of Rhetoric—and the publications Philosophy & Rhetoric and Rhetoric Review. Texts were selected and interpreted using a deconstructive reading and pluralistic and idiographic ideologies of history.

Although work on topical invention in the last century has neither a single coherent concept nor consistent terminology, it maintains a deep structure in which topics identify the sources for linkages that connect claims and conclusions to the data upon which they are based. This structure can be used to identify instances of topical invention in scholarly discussions and to analyze the shifts, trends, developments, and changes in topical invention over the last 100 years. The changes to, various conceptions of, and potential future developments for topical invention as evidenced by its shifting structure across the last century are presented in this dissertation.

Includes bibliographical references (p. 237-248).
Combining aesthetic theory with theories of the public sphere, this dissertation examines the brief appearance of a publicly empathetic civic realm in the United States during the 1940s. The argument begins with a reevaluation of the debate over monumentality initiated in modernist architectural circles, which included such figures as Sigfried Giedion, Lewis Mumford, Henry-Russell Hitchcock, and Philip Johnson. Centering on the city, this debate recast monumentality in terms more progressive than commemorative; it posited open-ended architectural and urban strategies that offered a non-restrictive yet sympathetic public resonance. If empathy is understood as the viewer's physical and psychological engagement with an object, then the 'publicly empathetic' collects and communicates the public 's individualized engagements. The term 'publicly empathetic' underscores the distinction between totalitarian consensus, exemplified by the modernism of Mussolini's fascist Italy, and what Alexis de Tocqueville identified in 1835 as America's collective individualism, which persisted in the 1940s under the umbrella of Franklin Roosevelt's New Deal. Springboarding from Ernst Cassirer and Susanne Langer's philosophies of symbolic form as unconsummated symbol, I argue that the modernism of this period did not define the public but rather expressed architecture's publicness through the recasting of form, programming, and modernism's public mandate. The chapters of this dissertation examine in turn the texts, projects and urbanism of this empathetic modernism. The projects constituting this realm are both public and private in nature; they include Charles Franklin and ...

Abstract:
In the late 1970's and 1980's, education issues formed a pivotal part of the American religious conservative agenda. The issues of school prayer, textbook content and the teaching of evolution in particular inspired lively debate and committed activism on the part of conservative Protestant leaders and activists. Confronting the behemoth of secular humanism, these leaders sought to win converts and to foment action in the converted through two separate modes of rhetoric: the emotional, which used impassioned arguments, and the intellectual, a more phlegmatic approach used to achieve political ends. Finding their roots in the 1920's, conservative Protestants have placed paramount importance on education issues throughout American history, believing that the United States is a fundamentally Christian nation, founded on a normative Protestant world view, and that American children should be taught according to these principles.

Abstract:
This thesis offers a new policy history of the National Endowment for the Arts, the federal agency responsible for providing grants to artists and arts organisations in the United States. It focuses in particular on the development of conservative perspectives on federal arts funding from the 1950s to the 1980s, and hence, illuminates the broader evolution of conservative political power, especially its limits. The most familiar narrative holds that the Endowment found itself caught up in the Culture Wars of the late 1980s when Christian right groups objected to certain federal grants, particularly to Andres Serrano's Piss Christ and Robert Mapplethorpe's Self-Portrait with Whip. This thesis, however, uncovers the older origins of conservative opposition to state support for the arts, analyses conservative conceptions of art, and illuminates the limited federal role the right sought to secure in the arts in the post-war period. Numerous studies have analysed the meanings and origins of the Culture Wars, but until now, scholars had not examined conservative approaches to federal arts politics in a historical sense. Historians have generally been too interested in explaining change to the detriment of examining continuity, but this approach under-emphasises the long-term tensions that underlie seemingly sudden political eruptions. This work also offers a deep account of the conservative movement and the arts world, an area that has so far been almost completely ignored by scholars, even though a focus on marginalised players is essential to understanding the limits of conservatism. In a general sense then, this thesis evaluates the range and diversity of the conservative movement and illuminates the overall odyssey of the right in modern America. In so doing, it provides a new insight into the ways we periodise political history and also invites a broader view of how we understand politics itself.

Abstract:
Pigmented structural glass started being produced in the early years of the twentieth century, reached its height in popularity during the 1930's, and was no longer produced by 1960s. Vitrolite was one of the most popular brands of pigmented structural glass, It was first used as a white glass background for decalcomania advertisements and as cladding in areas were sanitation was desired. Several types of applied decoration were developed for Vitrolite that helped to expand it's applications in building beyond sanitary applications. These types of decoration include painted, sand-blasted, inlaid, laminated, agate, and surface textured designs. Decorated Vitrolite was commonly used on store fronts, in signage, and for restaurant interiors and lobbies. All decorated Vitrolite was completed in the Vitrolite factory prior to shipping to customers. The processes of creating the various types of ornamentation, how they developed, and their applications are the focus of this thesis.

Full text
Abstract:
In the 1970s, Taiwan, officially known as the Republic of China (ROC),suffered a series of diplomatic setbacks. Nixon’s visit to Beijing in 1972 preluded the normalization between the United States (US) and the People’s Republic of China (PRC), as well as the estrangement between the Republic of China (ROC)and the US. A year before, Taiwan was forced to withdraw from the United Nations (UN). Many countries then ceased to cooperate with Taiwan and turned to the PRC. This made Taiwan the “Orphan of Asia”. To survive and prevent further isolation, Taiwan rallied support from the international community, especially the US, its old ally. It strengthened propaganda in the US and attempted to build a prosperous and democratic image of itself. It sought to appeal to the American public. This thesis investigates Taiwan’s propaganda activities in the US and explores how the Kuomintang (KMT) government built a favorable image of Taiwan during the 1970s. The most notable propaganda organization of the ROC was the Government Information Office (GIO). The GIO’s overseas branch in New York, the Chinese Information Service, launched propaganda campaigns in the US through organizing political, economic and cultural activities. Although the GIO was centrally responsible for propaganda, the execution of the campaigns was a product of collaboration between various government organizations. This thesis analyzes the GIO’s responsibilities within this network of collaboration. The thesis then explores the variety of Taiwan’s propaganda strategies. The KMT tried very hard to solicit support from different sectors in the US. They appealed to the general public by launching advertising campaigns, cultural exhibitions and art performances. Apart from the general public, they also targeted reporters, members of Congress and scholars by offering material benefits including free trips to Taiwan and academic funding. Several public relation firms were also hired to publicize Taiwan in the US media. Some of these publicity campaigns were even illegal. The overseas Chinese formed a large constituent to the Taiwan government’s propaganda efforts. However, the overseas Chinese were not a singular group of people and recognizing this, the GIO tailored their campaigns accordingly. Taiwan wooed Chinatown leaders by giving them financial benefits and educated Chinatown residents through controlling the Chinese media and Chinese language schools. Meanwhile, the KMT threatened and punished Taiwan Independence Movement supporters in American universities. They also made attempts to re-educate these supporters and their families in and out of Taiwan. Through these activities, Taiwan hoped to create an illusion that the KMT supporters were not limited to people in Taiwan, but included the majority of Chinese around the world. By examining Taiwan’s propaganda organizations and strategies in the 1970s, the thesis aims to expand our knowledge of US-PRC-ROC relations in the 1970s, and show how Taiwan adapted to the changing international environment.

Ruffing, Jason L. "A Century of Overproduction in American Agriculture." Thesis, University of North Texas, 2014. https://digital.library.unt.edu/ark:/67531/metadc700066/.

Full text
Abstract:
American agriculture in the twentieth century underwent immense transformations. The triumphs in agriculture are emblematic of post-war American progress and expansion but do not accurately depict the evolution of American agriculture throughout an entire century of agricultural depression and economic failure. Some characteristics of this evolution are unprecedented efficiency in terms of output per capita, rapid industrialization and mechanization, the gradual slip of agriculture's portion of GNP, and an exodus of millions of farmers from agriculture leading to fewer and larger farms. The purpose of this thesis is to provide an environmental history and political ecology of overproduction, which has lead to constant surpluses, federal price and subsidy intervention, and environmental concerns about sustainability and food safety. This project explores the political economy of output maximization during these years, roughly from WWI through the present, studying various environmental, economic, and social effects of overproduction and output maximization. The complex eco system of modern agriculture is heavily impacted by the political and economic systems in which it is intrinsically embedded, obfuscating hopes of food and agricultural reforms on many different levels. Overproduction and surplus are central to modern agriculture and to the food that has fueled American bodies for decades. Studying overproduction, or operating at rapidly expanding levels of output maximization, will provide a unique lens through which to look at the profound impact that the previous century of technological advance and farm legislation has had on agriculture in America.

Abstract:
One medium has dominated accounts of American art in the years following the Second World War. The period witnessed, in the words of one critic, a 'Triumph of American Painting', with advances in the easel picture far surpassing those in other media. Whilst more recent accounts have nuanced this view, drawing attention to developments in music and sculpture, literary contributions to the new American modernism have gone almost without assessment. Were there advances in literature comparable to those of Mark Rothko and Barnett Newman, David Smith and John Cage? Drawing extensively on his unpublished writings, After the New Failure of Nerve reveals the poet Charles Olson to have been the keenest literary advocate of the new American avant-garde and one of the most astute observers of its conditions and possibilities. Paying special attention to unpublished notes, lectures, and correspondence, the thesis utilises Olson's early writings in order to examine the momentum given early postwar modernism by a potent contemporary reaction against abstract rationality, a reaction identified at the time as a 'New Failure of Nerve'. Born of recent disillusionment with 'scientific' Marxism and New Deal progressivism, the thesis demonstrates the several ways in which this 'New Failure of Nerve' fuelled vanguard American art from the middle of the Second World War to the end of the decade. It argues that the new critique of abstract rationality - which was also reflected in the contemporary American work of the Frankfurt School - defined the way American artists understood the function of postwar modernism, the posture of the postwar modernist artist, and the status of the postwar modernist artwork. This pivotal moment in the history of modernism was shaped, I contend, by a philosophical critique explored most ambitiously by an American poet.

Full text
Abstract:
Twentieth-century environmentalist discourse often laid the blame for environmental degradation on Western civilization, and presented the religious traditions of the East as offering an ecocentric antidote to Western dualism and anthropocentrism. Gary Snyder has looked to Chinese and Japanese Buddhism to inform his environmentalist poetry and prose. While Snyder often writes in terms of a dualism of East and West, he synthesizes traditional forms of Buddhism with various Western traditions, and his green Buddhism ultimately undermines more simplistic oppositions of East and West. The first chapter reads Snyder's writing of the mid-1950s alongside several of his West Coast contemporaries - Kenneth Rexroth, Allen Ginsberg, Michael McClure, Philip Whalen and Jack Kerouac - showing that these writers evoked the natural world together with Buddhist themes before the advent of the modern environmental movement in order to mount a critique of Cold War American culture. Snyder's early interest in Buddhism was motivated largely by translations of Chinese poetry and Chapter Two examines his own translations of the Tang Dynasty poet Hanshan. In Snyder's translations and contemporaneous original poetry, Buddhist poetics mingle with American conceptions of wilderness. Chapter Three shows how Snyder's Buddhism was influenced by Anglophone writers such as D.T. Suzuki and Alan Watts, and argues that from the late 1960s Snyder aimed to Americanize Buddhism as ideas of localism became more central to his environmentalism. Chapter Four examines Snyder's synthesis of Hua-yen Buddhism and Western scientific ecology in the 1970s and 1980s. Chapter Five examines 'The Hokkaido Book,' an unfinished prose work on environmental attitudes in the Far East in which Snyder considers the relationship between the civilized and the primitive. Chapter Six examines the influence of Chinese landscape painting and Japanese No drama, two forms steeped in Buddhist ideas, on the poems of 'Mountains' and 'Rivers Without End'.

Abstract:
<p>At the turn of the 20th century, terra cotta flat arches (TCFA’s) were a popular floor system in steel framed buildings for industrial and office construction in the United States. These arches were lighter but just as fireproof as standard brick arches, and were designed empirically using proprietary allowable load tables, which were based mostly on load testing.</p><p>In the 21st century, the proprietary nature of the TCFA makes evaluating these systems problematic for the modern engineer, architect, and contractor. Renovations of buildings with TCFA floor assemblies typically will have new penetrations as well as altered loading conditions from its original construction.</p><p>It is important for all parties involved in the design and construction process of a renovation to understand the history, mechanisms, and limitations of TCFAs in order to have a successful renovation from both a design and a cost perspective. Conversely, renovating a building without the proper knowledge or experience with the existing materials can lead to change orders, time overruns, and most importantly life safety risks.</p><p>This paper is a summary of a presentation given by the same author to the Association for Preservation Technology (APT) conference in September, 2018. A more in-depth paper by the same author and colleagues Derek Trelstad and Rebecca Buntrock will appear as an article in the APT Bulletin in 2019.</p>

Fuentes, Gabriel. "The Politics of Memory: Constructing Heritage and Globalization in Havana, Cuba." In 2016 ACSA International Conference. ACSA Press, 2016. http://dx.doi.org/10.35483/acsa.intl.2016.60.

Full text
Abstract:
Since granted world heritage status by the United Nations Educational, Scientific, and Cultural Organization (UNESCO) in 1982, Old Havana has been the site of contested heritage practices. Critics consider UNESCO’s definition of the 143 hectare walled city center a discriminatory delineation strategy that primes the colonial core for tourist consumption at the expense of other parts of the city. To neatly bound Havana’s collective memory/history within its “old” core, they say, is to museumize the city as ”frozen in time,” sharply distinguishing the “historic” from the “vernacular.”While many consider heritage practices to resist globalization, in Havana they embody a complex entanglement of global and local forces. The Soviet Union’s collapse in 1991 triggered a crippling recession during what Fidel Castro called a“Special Period in a Time of Peace.” In response, Castro redeveloped international tourism—long demonized by the Revolution as associated with capitalist “evils”—in order to capture the foreign currency needed to maintain the state’s centralized economy. Paradoxically, the re-emergence of international tourism in socialist Cuba triggered similar inequalities found in pre-Revolutionary Havana: a dual-currency economy, government-owned retail (capturing U.S. dollars at the expense of Cuban Pesos), and zoning mechanisms to “protect” Cubanos from the “evils” of the tourism, hospitality, and leisure industries. Using the tropes of “heritage”and “identity,” preservation practices fueled tourism while allocating the proceeds toward urban development, using capitalism to sustain socialism. This paper briefly traces the geopolitics of 20th century development in Havana, particularly in relation to tourism. It then analyzes tourism in relation to preservation / restoration practices in Old Havana using the Plaza Vieja (Old Square)—Old Havana’ssecond oldest and most restored urban space—as a case study. In doing so, it exposes preservation/ restoration as a dynamic and politically complex practice that operates across scales and ideologies, institutionalizing history and memory as an urban design and identity construction strategy. The paper ends with a discussion on the implications of such practices for a rapidly changing Cuba.

Full text
Abstract:
A vast array of manufactured articles containing metal components utilize power press methods in their production. The common aspect of these methods is the use of specialized dies and the mechanical energy of the press machine to impart the required finished shape with a minimum of time and material loss. The innovation of power press metal forming methods in conjunction with advances in sheet rolling technology can be credited with a significant portion of the United States economic growth from manufacturing between 1890 and 1940. Of the many variations of power press metal forming processes that now exist, sheet stamping is found to be the most significant to the economic development of the U.S. as a synergetic partner of the new automobile industry. Data from the 1929 Census of Manufactures is used to generate a Social Savings metric which estimates the effect of the use of sheet stamping in terms productivity gained. The estimated Social Savings of this very small sector of manufacturing represents a tenth of one percent of the total Value Added by all U.S. industries in 1929.

Abstract:
Marked the 19th Century, “The Great Game” which took place between Great Britain and Imperial Russia, has determined the fates of many other nations. In practical sense, the term is expired in the first quarter of the 20th Century. States of Central and Southern Asia, involved in the strategic plans of Great Powers focused their interest to Central Asia in the 20th Century. Especially, after the collapse of the Soviet Union the strategicially important Kyrgyzstan has become an area of struggle between the United States, Russia, and strategically rising China in order to hold economic concessions. This paper tries to handle the strategic games played internationally on Kyrgyzstan addressing the reference frame of “The Great Game”.

Full text
Abstract:
The crisis at the turn of the 19th and 20th centuries affected different countries and different aspects of social life, which was inevitable both due to geographical proximity and cultural, economic, political and other intersections. Addressing the topic of the sociocultural crisis was characteristic of both Russian and Western European philosophers of the early 20th century. The author in the article refers to the understanding of its features and ways to overcome it in the context of the ideas of Russian religious philosophers. An integral feature of Russian philosophical thought in the context of assessing the ongoing social changes and the search for ways out of a crisis situation is an understanding of the special purpose of Russia and an awareness of its role in human history. The works of Russian philosophers are full of anxiety about the future of mankind, about the fate of Russia, a premonition of possible death, therefore it is no coincidence that the appeal to the theme of the Apocalypse, the impending catastrophe, the end of history is perceived as a real threat to the existence of mankind. With all the diversity of approaches to assessing the sociocultural crisis, Russian thinkers are united by common philosophical roots, religion, national and cultural traditions. In the context of understanding the crisis processes of the early twentieth century, Russian religious thinkers raise the question of the role and significance of a person in the transformation of life, thereby actualizing the moral and anthropological problems.

Abstract:
The purpose of seismic qualification of Structures, Systems and Components (SSCs) in nuclear power plants is to ensure that their intended safety function will not be compromised during and after a postulated earthquake event. The seismic performance of the equipment is generally evaluated using In-Structure Response Spectra (ISRS) at equipment-support locations as an input motion. Traditionally, these ISRS are generated based on design ground spectra prescribed by either U.S. Nuclear Regulatory Commission Regulatory Guide 1.60 or other design spectral shapes, which normally consider the frequencies content up to 33Hz. However, it has been recently recognized that probabilistic hazard-based site specific ground motion response spectra (GMRS) for Central and Eastern United States (CEUS) hard rock sites contains significant energy in the high frequency range, far beyond 33Hz. Since the motion at equipment support locations is highly affected by the dynamic characteristics of the soil or rock surrounding the building foundations and those of the structure itself, the adequacy of dynamic modeling and analysis techniques for determining the ISRS is critical to seismic qualification of safety-related equipment. This paper provides examples on dynamic modeling and analysis techniques required to accurately capture the structural responses for purposes of calculating ISRS throughout the frequency range of interest, including the high frequency responses typically expected at the CEUS sites. The discussion includes the selection of finite element mesh size, and sensitivity analysis performed to demonstrate that the propagation of these high frequencies through the different levels of the structure is properly captured. Other analytical considerations, such as the selection of time step size, for conducting time-history analysis, are also presented.

Abstract:
One of the biggest events in international political history at the end of the 20th century was end of the Cold War due to the dissolution of the Soviet Union. With the collapse of the Soviet Union in December 1991, the Cold War system, led by the US and the Soviet Union as the two main axes, disappeared into history, dramatically changing the international situation and creating new independent states in the international community. In the past, as the protagonist of the Silk Road civilization, it was a channel of trade and culture, linking the East and the West, but as members of the former Soviet Union, Central Asian countries whose importance and status were not well known have emerged on the international stage in the process of forming a new international order. After independence, Central Asia countries began to attract attention from the world as the rediscovery of the Silk Road, that is, the geopolitical importance of being the center of the Eurasian continent, and as a treasure trove of natural resources such as oil and gas increased.

Full text
Abstract:
Abstract In the past decades, financial institutions have led the way for companies to adhere to international standards for social performance. The journey began in the Industrial Revolution, when negative societal business impacts rapidly escalated, which led people to demand for their management. Initially focused on working conditions, impacts on the environment soon started to gain notice. Halfway through the 20th century, a combination of oil spills and mass media attention generated enough public pressure for the United States to sign the first piece of legislation requiring the environmental impact assessment. With this law and its replication abroad, however, came the concern with social impacts as well. Both environmental and social performance expectations soon spread internationally and, by the 1980s, multilateral financial institutions, most prominently the World Bank, incorporated such considerations into their investment and lending practices, which is the source of all such international standards today. These standards require the establishment of a social management system to integrate risk and impact management processes and stakeholder engagement activities. Given the challenge of implementing these requirements, a social risk management development framework is proposed to bring together the extensive and multidisciplinary demands of effective social performance. Five development areas are proposed: governance, social policy, tools, resourcing and capacity, and knowledge sharing. This is an important step to take today as it is expected that the next decades will see these international demands increase, possibly by ever increasing governmental regulation.

Abstract:
After 390 years of Spanish colonialism, Puerto Rico was ceded by Spain to the United States, as a result of the Spanish-American War and the Treaty of Paris. At the dawn of the 20th century, the situation on the Island was one of extreme poverty, high unemployment, and widespread illiteracy. Federal programs alleviated the situation on the Island but began to institutionalize a major problem: the evil of passively waiting for economic aid from abroad, instead of seeking to solve the problems by its own initiative.

Payne, Krista. Median Age at First Marriage, 2019. National Center for Family and Marriage Research, May 2021. http://dx.doi.org/10.25035/ncfmr/fp-21-12.

Full text
Abstract:
The median age at first marriage in the United States has increased steadily since the mid-20th century. In the mid-1950s, the median age was at a record low of just over 20 for women and 22 for men, but by 2020, the median age was 28 for women and 30 for men (see Figure 1). The median age at first marriage has increased similarly for both men and women. Consequently, the gender gap in the median age at first marriage has persisted, fluctuating between 1.6 and 2.7 years. This profile uses data from the 2019 American Community Survey (ACS), 1-year estimates to track the trends in women’s and men’s median ages at first marriage. The ACS is ideal because it provides the best annual data on marital status and demographic characteristics allowing for direct estimation of the median age at first marriage (Simmons & Dye, 2004). This is an update to our previous profiles on the topic for the years 2017 (FP-19-06), 2014 (FP-16-07), 2013 (FP-15-05), 2010 (FP-12-07), and 2008 (FP-09-03).

Abstract:
The November 25, 1988, moment magnitude 5.9 (Mw) Saguenay earthquake is one of the largest eastern Canadian earthquakes of the 20th century. It was preceded by a magnitude (MN) 4.7 foreshock and followed by very few aftershocks considering the magnitude of the main shock. The largest aftershock was a magnitude (MN) 4.3 event. This Open File (OF) Report presents a variety of documents (including original and interpreted felt information, images, newspaper clippings, various engineering reports on the damage, mass movements). This OF updates the report of Cajka and Drysdale (1994) with additional material, including descriptions of the foreshock and largest aftershock. Most of the felt report information come from replies of a questionnaire sent to postmasters in more than 2000 localities in Canada and in the United States. Images of the original felt reports from Canada are included. The OF also includes information gathered in damage assessments and newspaper accounts. For each locality, the interpreted information is presented in a digital table. The fields include the name, latitude and longitude of the municipality and the interpreted intensity on the Modified Mercalli Intensity (MMI) scale (most of which are the interpretations of Cajka and Drysdale, 1996). When available or significant, excerpts of the felt reports are added. This OF Report also includes images from contemporary newspapers that describe the impact. In addition, information contained in post-earthquake reports are discussed together with pictures of damage and mass movements. Finally, a GoogleEarth kmz file is added for viewing the felt information reports within a spatial tool.
