BACKGROUND In the last few decades, the literature related to Internet of Medical Things (IoMT) has grown rapidly. Obviously, widespread application of IoMT is helpful for considerably improving the efficiency of medical services. In addition, IoMT enables economies and societies to develop in a sustainable way to some extent. However, little is known about the panorama of IoMT-related research based on a visualization approach and bibliometrics. OBJECTIVE The purpose of this study was to deeply detect the knowledge structure, including literature distribution, clustering of keywords and topic evolution of IoMT-related research, by analyzing the current publication outputs related to IoMT. METHODS We conducted various bibliometric analyses on IoMT-related literature, including publication growth analysis, and the distribution of core countries and journals. Then, keyword co-occurrence analysis, as well as temporal visualization bar, was performed based on the bibliographic records during the period from 1997 to 2018. RESULTS A total of 6415 bibliographic records related to IoMT were identified. The United States and China take the lead in the publication output related to IoMT, followed by Korea, United Kingdom, and India. Furthermore, the collaboration between continents as well as countries is uneven; North America and Asia have the greatest frequent cooperation with other continents, mainly owing to the great contribution of the United States and China. There are 6 important research directions identified, with an imbalanced state. Moreover, these 6 topics can be further categorized into 3 areas: (1) Technologies and devices of IoMT, (2) Healthcare applications, and (3) Security and privacy. Finally, the evolution of topic were identified, namely from “basic research” through “hardware and software updates” to “application of new technologies”. CONCLUSIONS This study provides important insights into the knowledge structure of IoMT. Cooperation among countries is not balanced, and the main research content of IoMT is the application of new technologies in recent years. Moreover, user security and privacy issues are also hotspots in the future. All of these are helpful for scholars and institutions worldwide to obtain the basis for comprehensive understanding and potential guidance in future research in this field, which can further enhance the sustainable development of countries.

Background: Retinoblastoma is the most common primary intraocular malignancy of childhood. Despite high survival and eye salvage as the result of various types of therapies, retinoblastoma remains a disease that places a considerable burden on developing countries. Our study attempted to analyse the research trends in retinoblastoma research and compare contributions from different countries, institutions, journals, and authors.Methods: We extracted all publications concerning retinoblastoma from 2001 to 2021 from the Web of Science database. Microsoft Excel and VOSviewer were employed to collect publication data, analyse publication trends, and visualize relevant results.Results: A total of 1,675 publications with 30,148 citations were identified. The United States contributed the most publications (643) and citations (16,931 times) with the highest H-index value (67) as of February 4, 2021. China ranked second in the number of publications (259), while ranking fourth in both citations (2,632 times) and the H-index (26) ranked fourth. The British Journal of Ophthalmology was the most productive journal concerning retinoblastoma, and Abramson DH had published the most papers in the field. Keywords were categorized into three clusters; tumor-related research, clinical research, and management-related research. The keywords “intravitreal,” “intraarterial,” and “intravenous” appeared the most frequently, with the average appearing year being 2018.1, 2017.7, and 2017.1, respectively. Management-related research has been recognized as a heavily researched topic in the field.Conclusion: We conclude that the United States, China, and India made the most exceptional contributions in the field of retinoblastoma research, while China still has a disparity between the quantity and quality of publications. Management-related research, including intravitreal, intraarterial, and intravenous chemotherapy was considered as a potential focus for future research.

As the demand and production for renewable energies increases there is a growing need to research new technologies to increase the efficiency, productivity and profitability of production. This study aimed to investigate the priorities of bioenergy stakeholders on Geographic Information Systems based research in a variety of countries including a number throughout Europe, the United States and Australia. A voluntary questionnaire was distributed internationally to bioenergy stakeholders to discern perceived usefulness ratings for various analytics. Participants rated Economic analytics as the most useful followed by Environmental, Product quality and Social assessments. Therefore, future research within the bioenergy sector should be aimed at increasing the economic viability of bioenergy and decreasing its environmental impact. There was a difference between analytic preference and the thirteen countries surveyed and the stakeholder type however, this relationship was not significant.

BACKGROUND In the last few decades, mobile technologies have been widely adopted in the field of health care services to improve the accessibility to and the quality of health services received. Mobile health (mHealth) has emerged as a field of research with increasing attention being paid to it by scientific researchers and a rapid increase in related literature being reported. OBJECTIVE The purpose of this study was to analyze the current state of research, including publication outputs, in the field of mHealth to uncover in-depth collaboration characteristics and topic burst of international mHealth research. METHODS The authors collected literature that has been published in the last 20 years and indexed by Thomson Reuters Web of Science Core Collection (WoSCC). Various statistical techniques and bibliometric measures were employed, including publication growth analysis; journal distribution; and collaboration network analysis at the author, institution, and country collaboration level. The temporal visualization map of burst terms was drawn, and the co-occurrence matrix of these burst terms was analyzed by hierarchical cluster analysis and social network analysis. RESULTS A total of 2704 bibliographic records on mHealth were collected. The earliest paper centered on mHealth was published in 1997, with the number of papers rising continuously since then. A total of 21.28% (2318/10,895) of authors publishing mHealth research were first author, whereas only 1.29% (141/10,895) of authors had published one paper. The total degree of author collaboration was 4.42 (11,958/2704) and there are 266 core authors who have collectively published 53.07% (1435/2704) of the total number of publications, which means that the core group of authors has fundamentally been formed based on the Law of Price. The University of Michigan published the highest number of mHealth-related publications, but less collaboration among institutions exits. The United States is the most productive country in the field and plays a leading role in collaborative research on mHealth. There are 5543 different identified keywords in the cleaned records. The temporal bar graph clearly presents overall topic evolutionary process over time. There are 12 important research directions identified, which are in the imbalanced development. Moreover, the density of the network was 0.007, a relatively low level. These 12 topics can be categorized into 4 areas: (1) patient engagement and patient intervention, (2) health monitoring and self-care, (3) mobile device and mobile computing, and (4) security and privacy. CONCLUSIONS The collaboration of core authors on mHealth research is not tight and stable. Furthermore, collaboration between institutions mainly occurs in the United States, although country collaboration is seen as relatively scarce. The focus of research topics on mHealth is decentralized. Our study might provide a potential guide for future research in mHealth.

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.

We have investigated the differences in support for the U.S. Supreme Court among black, Hispanic, and white Americans, catalogued the variation in African Americans’ group attachments and experiences with legal authorities, and examined how those latter two factors shape individuals’ support for the U.S. Supreme Court, that Court’s decisions, and for their local legal system. We take this opportunity to weave our findings together, taking stock of what we have learned from our analyses and what seem like fruitful paths for future research. In the process, we revisit Positivity Theory. We present a modified version of the theory that we hope will guide future inquiry on public support for courts, both in the United States and abroad.

Advancements in technologies and their mass-scale adoption throughout the United States create rapid changes in how people interact with the environment and each other and how they live and work. As technologies become commonplace in society through increased availability and affordability, several problems may emerge, including disparate use among groups, which creates divides in attainment of the beneficial aspects of a technology’s use and coinciding mental health issues. This chapter briefly overviews new technologies and associated emerging applications in information communication technologies, social media networks, video games and massively multiplayer online role-playing games, and online gambling, then examines the prevalence of use among the general population and its subgroups and further discusses potential links between mental health issues associated with each technology and implications of overuse.

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.

Despite widespread suspicion to the contrary, secular living can and does serve as an adequate, or even excellent, context for moral development. In this chapter, the authors present the contours of contemporary anti-atheist prejudice, with an emphasis on the United States. Next, they explore the empirical data showing that individual atheists and highly secularized societies, such as Sweden and Denmark, are often quite moral, which serves to counter and debunk anti-atheist prejudice. Then, the authors move to a philosophical discussion centering around secular morality itself, outlining general merits of atheistic morality specifically while simultaneously pointing out various problematic assumptions of theistic morality. Finally, the authors conclude and make recommendations for future research.

Do demographic shifts in the racial composition of the United States promote positive changes in the nation’s racial dynamics? Change in response to the nation’s growing diversity is likely, but its direction and scope are less clear. This review integrates emerging social-scientific research that examines how Americans are responding to the projected changes in the racial/ethnic demographics of the United States. Specifically, we review recent empirical research that examines how exposure to information that the United States is becoming a “majority-minority” nation affects racial attitudes and several political outcomes (e.g., ideology, policy preferences), and the psychological mechanisms that give rise to those attitudes. We focus primarily on the reactions of members of the current dominant racial group (i.e., white Americans). We then consider important implications of these findings and propose essential questions for future research.
