Mass Timber

<p>The use of mass timber as a structural element is not a new phenomenon. For example, within almost every major city in the world, there are upscale enclaves centered around the adaptive reuse of factories and warehouses from the late 19th and early 20th centuries. These former industrial structures are almost always constructed from masonry and mass timber.</p><p>Within the past decade, the building industry has seen a renewed interest in mass timber structures. This resurgence has been fueled by several trends, including the mass production of Cross Laminated Timber (CLT) and a growing awareness of mass timber’s sustainable advantages. A number of high-profile heavy timber structures have found commercial success in the United States and abroad. Leading architectural practices such as Skidmore Owings &amp; Merrill (SOM) have used research initiatives like the Timber Tower Research Project to jump-start a fertile debate within the design industry. On the demand side, building owners have pushed the design community to find innovative ways to incorporate mass timber into their projects.</p><p>This interest has often driven designers and builders to aggressively distinguish their projects from predecessors, pushing for pure mass timber structures while giving less consideration to hybrid structures (mass timber and masonry/concrete structures). This bias towards material purity risks ignoring important lessons from the past and may in some cases lead to inefficient structural choices and structures with less durability and sustainability than their hypothetical hybrid counterparts.</p><p>This paper posits that some of the energy generated by a resurgence in mass timber construction would be well spent on understanding, celebrating, and rediscovering the elegance and importance of hybrid structures.</p>

Community Healing

Community healing and reconciliation have been a focus of many nations in response to civil war, genocide, and other conflicts. There have been increasing numbers of high-profile murders of African-American youths in the United States over the past 10 years. This article provides an overview of gun violence and its effects on African-American youths. Sanford, Florida, and Cleveland, Ohio, experienced the murders of Trayvon Martin and Tamir Rice, and the responses of the cities will be highlighted. The two cities provide potential models by communities to address historical injustices in the aftermath of high-profile fatal black male tragedies.

Publication Patterns

The authors in this article first identify the extent to which research articles published in three American Speech-Language-Hearing Association (ASHA) journals included participants, age birth to 18 years, from international backgrounds (i.e., residence outside of the United States), and go on to describe associated publication patterns over the past 12 years. These patterns then provide a context for examining variation in the conceptualization of ethnicity on an international scale. Further, the authors examine terminology and categories used by 11 countries where research participants resided. Each country uses a unique classification system. Thus, it can be expected that descriptions of the ethnic characteristics of international participants involved in research published in ASHA journal articles will widely vary.

Abstract. Background: In recent years, the rate of death by suicide has been increasing disproportionately among females and young adults in the United States. Presumably this trend has been mirrored by the proportion of individuals with suicidal ideation who attempted suicide. Aim: We aimed to investigate whether the proportion of individuals in the United States with suicidal ideation who attempted suicide differed by age and/or sex, and whether this proportion has increased over time. Method: Individual-level data from the National Survey on Drug Use and Health (NSDUH), 2008–2017, were used to estimate the year-, age category-, and sex-specific proportion of individuals with past-year suicidal ideation who attempted suicide. We then determined whether this proportion differed by age category, sex, and across years using random-effects meta-regression. Overall, age category- and sex-specific proportions across survey years were estimated using random-effects meta-analyses. Results: Although the proportion was found to be significantly higher among females and those aged 18–25 years, it had not significantly increased over the past 10 years. Limitations: Data were self-reported and restricted to past-year suicidal ideation and suicide attempts. Conclusion: The increase in the death by suicide rate in the United States over the past 10 years was not mirrored by the proportion of individuals with past-year suicidal ideation who attempted suicide during this period.

Past Half

Japan and the United States, the world’s largest economies for most of the past half century, have very different immigration policies. Japan is the G7 economy most closed to immigrants, while the United States is the large economy most open to immigrants. Both Japan and the United States are debating how immigrants are and can con-tribute to the competitiveness of their economies in the 21st centuries. The papers in this special issue review the employment of and impacts of immigrants in some of the key sectors of the Japanese and US economies, including agriculture, health care, science and engineering, and construction and manufacturing. For example, in Japanese agriculture migrant trainees are a fixed cost to farmers during the three years they are in Japan, while US farmers who hire mostly unauthorized migrants hire and lay off workers as needed, making labour a variable cost.

Western Democracies

It's a commonplace occurrence that citizens in Western democracies are disaffected with their political leaders and traditional democratic institutions. But this book argues that this crisis of confidence is partly a crisis of understanding. The book makes the case that the sources of democratic legitimacy have shifted and multiplied over the past thirty years and that we need to comprehend and make better use of these new sources of legitimacy in order to strengthen our political self-belief and commitment to democracy. Drawing on examples from France and the United States, the book notes that there has been a major expansion of independent commissions, NGOs, regulatory authorities, and watchdogs in recent decades. At the same time, constitutional courts have become more willing and able to challenge legislatures. These institutional developments, which serve the democratic values of impartiality and reflexivity, have been accompanied by a new attentiveness to what the book calls the value of proximity, as governing structures have sought to find new spaces for minorities, the particular, and the local. To improve our democracies, we need to use these new sources of legitimacy more effectively and we need to incorporate them into our accounts of democratic government. This book is an original contribution to the vigorous international debate about democratic authority and legitimacy.

By identifying two general issues in recent history textbook controversies worldwide (oblivion and inclusion), this article examines understandings of the United States in Mexico's history textbooks (especially those of 1992) as a means to test the limits of historical imagining between U. S. and Mexican historiographies. Drawing lessons from recent European and Indian historiographical debates, the article argues that many of the historical clashes between the nationalist historiographies of Mexico and the United States could be taught as series of unsolved enigmas, ironies, and contradictions in the midst of a central enigma: the persistence of two nationalist historiographies incapable of contemplating their common ground. The article maintains that lo mexicano has been a constant part of the past and present of the US, and lo gringo an intrinsic component of Mexico's history. The di erences in their historical tracks have been made into monumental ontological oppositions, which are in fact two tracks—often overlapping—of the same and shared con ictual and complex experience.

This essay delineates the issues concerning AAPI art exhibitions from a curator’s perspective, particularly in response to the changing racial demographics and economics of the past decades. A discussion of practical, curatorial problems offers the reader an overview of the obstacles and reasons behind the lack of exhibitions of AAPI works in the United States. It is the author’s hope that by understanding the challenges particular to AAPI exhibitions, community leaders, and patrons will direct future financial support to appropriate museum operations, which in turn will encourage more exhibitions and research of the important artistic contribution of AAPI artists to American art.

Regime Transitions

In regime transitions, a number of mechanisms are utilized to memorialize the past and to reject the ideas associated with human rights abused of the prior regime. This is often done through truth commissions, apologies, memorials, museums, changes in place names, national holidays, and other symbolic measures. In the United States, some efforts along these lines have been undertaken, but on the whole they have been very limited and inadequate. In addition, many symbols and memorials associated with the past, such as Confederate monuments and the Confederate Battle Flag, continue to be displayed. Hence while some progress has been made on these issues, much more needs to be done.
