Microsurfacing has been utilized in the United States since 1980 as a maintenance treatment for pavement. This paper reviews the benefits, limitations, and factors that contribute to successful applications of microsurfacing. The history of microsurfacing, as well as a definition and process description of the treatment, is included. The body of scientific work on microsurfacing is shown to promote its use in preventative maintenance programs, and the potential for microsurfacing to meet tightening environmental and budgetary restrictions is discussed. Suggestions are given for future research to expand microsurfacing’s applications and efficacy stemming from the ability of microsurfacing to be cold-applied and utilize polymers in the bitumen.

The cover photograph for this issue of Public Voices was taken sometime in the summer of 1929 (probably June) somewhere in Sunflower County, Mississippi. Very probably the photo was taken in Indianola but, perhaps, it was Ruleville. It is one of three such photos, one of which does have the annotation on the reverse “Ruleville Midwives Club 1929.” The young woman wearing a tie in this and in one of the other photos was Ann Reid Brown, R.N., then a single woman having only arrived in the United States from Scotland a few years before, in 1923. Full disclosure: This commentary on the photo combines professional research interests in public administration and public policy with personal interests—family interests—for that young nurse later married and became the author’s mother. From the scholarly perspective, such photographs have been seen as “instrumental in establishing midwives’ credentials and cultural identity at a key transitional moment in the history of the midwife and of public health” (Keith, Brennan, & Reynolds 2012). There is also deep irony if we see these photographs as being a fragment of the American dream, of a recent immigrant’s hope for and success at achieving that dream; but that fragment of the vision is understood quite differently when we see that she began a hopeful career working with a Black population forcibly segregated by law under the incongruously named “separate but equal” legal doctrine. That doctrine, derived from the United States Supreme Court’s 1896 decision, Plessy v. Ferguson, would remain the foundation for legally enforced segregation throughout the South for another quarter century. The options open to the young, white, immigrant nurse were almost entirely closed off for the population with which she then worked. The remaining parts of this overview are meant to provide the following: (1) some biographical information on the nurse; (2) a description, in so far as we know it, of why she was in Mississippi; and (3) some indication of areas for future research on this and related topics.

This chapter offers a historiographic survey of country music scholarship from the publication of Bill C. Malone’s “A History of Commercial Country Music in the United States, 1920–1964” (1965) to the leading publications of the today. Very little of substance has been written on country music recorded since the 1970s, especially when compared to the wealth of available literature on early country recording artists. Ethnographic studies of country music and country music culture are rare, and including ethnographic methods in country music studies offers new insights into the rich variety of ways in which people make, consume, and engage with country music as a genre. The chapter traces the influence of folklore studies, sociology, cultural studies, and musicology on the development of country music studies and proposes some directions for future research in the field.

Abstract This article introduces the field of trans pornography studies and makes a case for why studying it matters. We locate trans pornography within the broader field of porn studies, while also pointing to its importance to transgender studies. We map the history of trans pornography and examine the wider social, political, and economic forces contributing to the transformation of trans porn into a genre of mainstream straight porn. We discuss the economic organization of the trans porn industry and current industry trends, including geographical shifts in production and the rise of alternative production platforms. We address areas of future research and the need for more scholarship on the political economy of the trans porn industry, audiences and consumers, transmasculine representation in pornography, and research that focuses on trans porn production outside the United States.

Seeing in the last number of the Canadian Entomologist, a description of the egss of A. Luna, reminds me to ask of you the explanation of a curious circumstance in the life-history of one bred by me from the larva last year. I will premise that I am writing without my notes, and therefore cannot give figures accurately, but can give the facts. There may be nothing very strange about it, but two of the best entomologists in the United States inform me that it is entirely new to them. It is this:–Some time in the latter part of the summer of 1868 I took, feeding on walnut leaves, a mature larva of A. Luna; from which I did not houi to rear the mature insect, because I counted on the larva over twenty eggs like those of a Tachina, Underneath some of the eggs I could discern with a lens a minute opening through which the fly-larva had entered the body of the Luna larva. The skin of the latter was more or less discoloured under each egg, but under some-under many in fact there was a dense black spot, sometimes two lines in diameter.

My dissertation traces the invention and development of a new form of banking, body banking. Today, the body bank as an institution that collects, stores, processes, and distributes a human body product is a taken-for-granted aspect of medicine in the United States. We donate to blood banks, we cherish sperm bank babies, and we contemplate many sorts of banks, including cord blood banks, gene banks, and egg banks. Such institutions have existed for the past century in the metaphorical shadow of financial banks, and like those better-studied banks have stirred considerable controversy. The driving question behind my dissertation is simply, why banks? How did we come to use “bank” to apply to bodies as well as to dollars? More intriguingly, what does this analogy show us and what is it hiding?

Abstract Objectives During the coronavirus disease 2019 (COVID-19) pandemic, older adults have been disproportionately affected by high rates of health complications and mortality. Reactions toward older adults included a mix of prosocial behaviors and ageist responses, consistent with the history of positive and negative views and treatment of older adults in the United States. Methods In a two-part study (n = 113, Mage = 18.49, SD = 0.50; range 18–19), we examined whether pre-pandemic ageism among undergraduates predicts prosocial behavioral intentions toward older adults both specific to COVID-19 and in general. Results Pre-pandemic ageism toward older adults predicted less intentions to help older adults generally and specific to COVID-19. Whereas viewing older adults as incompetent predicted greater intentions to help specific to COVID-19. Discussion These results reflect the complexity of predicting helping behaviors and suggest that even supportive behaviors toward older adults during the COVID-19 pandemic may be rooted in negative ageist stereotypes. Implications and directions for future research are discussed.

In this study, we characterize the body of knowledge of groundwater remediation from 1950 to 2018 by employing scientometric techniques and CiteSpace software, based on the Science Citation Index Expanded (SCI-E) databases. The results indicate that the United States and China contributed 56.4% of the total publications and were the major powers in groundwater remediation research. In addition, the United States, Canada, and China have considerable capabilities and expertise in groundwater remediation research. Groundwater remediation research is a multidisciplinary field, covering water resources, environmental sciences and ecology, environmental sciences, and engineering, among other fields. Journals such as Environmental Science and Technology, Journal of Contaminant Hydrology, and Water Research were the major sources of cited works. The research fronts of groundwater remediation were transitioning from the pump-and-treat method to permeable reactive barriers and nanoscale zero‑valent iron particles. The combination of new persulfate ion‑activation technology and nanotechnology is receiving much attention. Based on the visualized networks, the intelligence base was verified using a variety of metrics. Through landscape portrayal and developmental trajectory identification of groundwater remediation research, this study provides insight into the characteristics of, and global trends in, groundwater remediation, which will facilitate the identification of future research directions.

This chapter reviews the argument and evidence presented in the body of book, which provides substantial support for the proposed theories on the sources and effectiveness of US nonproliferation policy. It identifies areas for future research, such as the nonproliferation policies of other countries, the mechanisms through which nuclear domino effects occur, and the role of preventive strikes in preventing the spread of nuclear weapons. It also discusses the implications of the book’s finding for theory and policy, for example the need for the United States to maintain a credible sanctions policy, continue its international engagement, and work to develop more reliable policies for instituting multilateral sanctions.

Sociologists have long studied subnational development across the United States focusing on state and market forces that contribute to spatial inequality and uneven development. Subnational research is central to development sociology's concern with the present neoliberal stage of capitalism and to numerous theoretical, substantive, and policy issues that revolve around poverty and prosperity within the nation. Yet the body of work faces a number of challenges. Research is fragmented and its potential for building broader development sociology overlooked. We provide a critical analysis of this research tradition focusing on its theoretical development and identifying a wave of shifts in economic structure and the state that require new engagement. Our analysis raises challenges for development sociology as a broader field of study. Profound state and market changes are unfolding within the United States but they remain under-theorized with implications for limiting progress in the field as a whole. We identify a series of questions that offer promising directions for future research.

In 1977, the federal government launched the nation's largest and most significant program to collect data on the registered nurse (RN) workforce of the United States—the National Sample Survey of Registered Nurses (NSSRN). This survey is conducted by the U.S. Health Resources and Services Administration, first in 1977 and then every 4 years since 1980. This article offers the history of the NSSRN and a review of the ways in which the NSSRN data have been used to examine education, demographics, employment, shortages, and other aspects of the RN workforce. The influence this body of research has had on policymaking is explored. Recommendations for future research are offered, in the hope that future waves of the NSSRN will continue to be used to their fullest potential.
