Recent developments in remote imaging equipment carried on satellites have given the scientific community a vast amount of new information about the Sun and its atmosphere. Media coverage of the remarkable discoveries accompanied by impressive images of the Sun's atmosphere, and linkage to the loss of a television satellite over the United States, have focused public attention on the existence and effects of the Solar Wind. This paper sets out to illustrate the impact of the Solar Wind on radio aids to navigation, and to look at the possible effects on present and proposed systems.

ABSTRACT Recent media coverage has focused on the supply of physicians in the United States, especially with the impact of a growing physician shortage and the Affordable Care Act. State medical boards and other entities maintain data on physician licensure and discipline, as well as some biographical data describing their physician populations. However, there are gaps of workforce information in these sources. The Federation of State Medical Boards' (FSMB) Census of Licensed Physicians and the AMA Masterfile, for example, offer valuable information, but they provide a limited picture of the physician workforce. Furthermore, they are unable to shed light on some of the nuances in physician availability, such as how much time physicians spend providing direct patient care. In response to these gaps, policymakers and regulators have in recent years discussed the creation of a physician minimum data set (MDS), which would be gathered periodically and would provide key physician workforce information. While proponents of an MDS believe it would provide benefits to a variety of stakeholders, an effort has not been attempted to determine whether state medical boards think it is important to collect physician workforce data and if they currently collect workforce information from licensed physicians. To learn more, the FSMB sent surveys to the executive directors at state medical boards to determine their perceptions of collecting workforce data and current practices regarding their collection of such data. The purpose of this article is to convey results from this effort. Survey findings indicate that the vast majority of boards view physician workforce information as valuable in the determination of health care needs within their state, and that various boards are already collecting some data elements. Analysis of the data confirms the potential benefits of a physician minimum data set (MDS) and why state medical boards are in a unique position to collect MDS information from physicians.

One of the most important demands imposed by the consumer market on the Brazilian Productive Chain of Flowers and Ornamental Plants is the constant launching of innovations in cultivated species and varieties. Such innovations include the constant introduction of flowers and plants not yet grown and commercialized, both native and adapted exotic species, as well as transformations and changes in size, shape, coloring and conduction patterns and presentation of these goods to the market. Brazil does not have a relevant breeding and cultivation industry. In this sense, it is highly dependent on imports of genetic material developed by countries such as the Netherlands, Germany, Japan, the United States of America, Thailand, among others. Recent developments in the sectoral policy to protect the rights of genetic developers, in the development of internationally adequate legislation and in the control of the use and trade of cultivars, has allowed Brazil greater access to new genetic materials of high quality and in line with contemporary international trends in the consumption. This article aims to discuss the state of the art of protection of cultivars in Brazil, pointing to the advances that the legislation and the inspection have allowed in relation to the introduction of genetic innovations, evaluating the impact of these measures on the growth and development of the market of consumption of flowers and ornamental plants in the country.

This chapter examines loneliness and how it affects health and well-being. It discusses how loneliness may lead to ill health but also how ill health may lead to feelings of loneliness. It reviews the evidence suggesting that loneliness is not only linked to overall morbidity and mortality in older adults but also a major predictor of psychological distress. With the global growth of the aging population, considerable research attention focuses on these issues in Europe, the United States, and Australia. The proportion of Australians aged 65 years or older is growing, with prevalence rates of loneliness among older adults as high as 30%. The impact of this is discussed in this chapter, as are recent developments, current conditions, historical trends, transnational feminism and advocacy, and how loneliness impacts the health and well-being of older women in Australia.

Abstract Harmful and sudden events trigger intense media coverage which in turn can elevate public interest in a problem within an instant. A period of heavy air pollution in Beijing in January 2013 may have been such a case. This sudden and intense period of air pollution featured historically high levels of fine particulate concentrations and was assumed by observers to be a trigger for shifting public perception and increased pressure for policy adjustment. This study examines whether this period of severe air pollution indeed triggered increased public scrutiny, following which the influential factors behind this development are outlined. In this context, a focus is given to the interplay of air quality, media reporting and public discussion in shaping sustained public interest. Based on a timeline analysis and survey data, it is argued that the combination of historically high air pollution with intense media reporting did lead to higher public attention to the topic.

This article reflects upon recent developments in sex offender tracking and monitoring. Taking as its focus a suite of mobile applications available for use in the United States, the author explores the impact and consequences of remediating the data held by State offender databases. The article charts the recent history of techno-corrections as it applies to this category of criminal, before then undertaking an analysis of current remediation of this legally obtained data. In doing so, the author identifies how the recontextualizing of data serves to (re)negotiate the relationship between the user, the database and registered sex offenders. The author concludes by arguing that the (mobile) mapping of offender databases serves to obscure the original intentions of these recording mechanisms and might hinder their effectiveness in reducing sex offending.

The top 1 percent income share has more than doubled in the United States over the last 30 years, drawing much public attention in recent years. While other English-speaking countries have also experienced sharp increases in the top 1 percent income share, many high-income countries such as Japan, France, or Germany have seen much less increase in top income shares. Hence, the explanation cannot rely solely on forces common to advanced countries, such as the impact of new technologies and globalization on the supply and demand for skills. Moreover, the explanations have to accommodate the falls in top income shares earlier in the twentieth century experienced in virtually all high-income countries. We highlight four main factors. The first is the impact of tax policy, which has varied over time and differs across countries. Top tax rates have moved in the opposite direction from top income shares. The effects of top rate cuts can operate in conjunction with other mechanisms. The second factor is a richer view of the labor market, where we contrast the standard supply-side model with one where pay is determined by bargaining and the reactions to top rate cuts may lead simply to a redistribution of surplus. Indeed, top rate cuts may lead managerial energies to be diverted to increasing their remuneration at the expense of enterprise growth and employment. The third factor is capital income. Overall, private wealth (relative to income) has followed a U-shaped path over time, particularly in Europe, where inherited wealth is, in Europe if not in the United States, making a return. The fourth, little investigated, element is the correlation between earned income and capital income, which has substantially increased in recent decades in the United States.

This study examined recent virality of “Ok Boomer” in the United States. The term of Ok Boomer gained overnight momentum in the public sphere as the symbol of a generational war. While previous research has primarily examined racial and gender tensions, this study introduced a new phenomenon of the generational conflict between “Ok Boomers” and “Baby Boomers,” in which social media originated the term of Ok Boomer and traditional media diffused it with framed meaning. Diffusion of Innovation theory was used to better understand the path of how “Ok Boomer” as a catchphrase, hashtag, noun cluster or trend resulted in attracting a massive amount of media and public attention. Relying on Node XL, Google Trends, and Nexus Nexis for data gathering and analyses, this study categorized four themes for a word, or an idea as an innovation to be publicly acknowledged: collaboration of social media and traditional media, public figures’ involvement for debate; confrontational social issues, and media-framed agenda. In sum, this study argues the term of Ok Boomer symbolizes the advent of a generational war in society in line with the long-standing race and gender wars in the media coverage.

This study aims to identify factors that shape public perception and emotional response to mass shootings in the United States. I suggest that patterns of media coverage inform public consciousness and collective emotion. Newsworthiness and gatekeeping theories assert that school or prejudicial shootings and those with more victims are reported on at higher rates. Literature on racial and immigrant bias in media demonstrates that non-white shooters also generate more discourse. The directed construction of shootings and the affective public responses they generate align well with the concept of a “moral panic.” Using all valid cases from the Mother Jones Mass Shootings:1982-2019 dataset which align temporally with Google Trends data, I analyze the volume and decay rate of search topics “mass shooting,” “gun control,” and “open carry,” following US mass shootings from 2004-2019. Shootings with more victims predict a higher volume of searches for “mass shooting,” and shorter search periods for “gun control” and “open carry.” Shootings with educational and religious targets had no significant effects on search patterns. Workplace shootings result in longer search periods for “mass shooting,” and shorter periods for “gun control.” Non-white shooters generate shorter search decay for “open carry.” The results support theories of media gatekeeping, suggesting events with more casualties generate more intense public attention. The consistent negative correlation between search volume and decay length suggests that sensational responses to shootings are not sustainable over long periods of time and prohibit pragmatically addressing mass shootings.

AbstractIn recent years, many studies have drawn attention to the important role of collective awareness and human behaviour during epidemic outbreaks. A number of modelling efforts have investigated the interaction between the disease transmission dynamics and human behaviour change mediated by news coverage and by information spreading in the population. Yet, given the scarcity of data on public awareness during an epidemic, few studies have relied on empirical data. Here, we use fine-grained, geo-referenced data from three online sources – Wikipedia, the GDELT Project and the Internet Archive – to quantify population-scale information seeking about the 2016 Zika virus epidemic in the U.S., explicitly linking such behavioural signal to epidemiological data. Geolocalized Wikipedia pageview data reveal that visiting patterns of Zika-related pages in Wikipedia were highly synchronized across the United States and largely explained by exposure to national television broadcast. Contrary to the assumption of some theoretical models, news volume and Wikipedia visiting patterns were not significantly correlated with the magnitude or the extent of the epidemic. Attention to Zika, in terms of Zika-related Wikipedia pageviews, was high at the beginning of the outbreak, when public health agencies raised an international alert and triggered media coverage, but subsequently exhibited an activity profile that suggests nonlinear dependencies and memory effects in the relation between information seeking, media pressure, and disease dynamics. This calls for a new and more general modelling framework to describe the interaction between media exposure, public awareness and disease dynamics during epidemic outbreaks.

<p>During the early Cold War, America was gripped by an intense domestic Red Scare. This thesis explores how the United States Supreme Court dealt with the Alien Registration Act (Smith Act) and the issue of freedom of speech in the context of that Red Scare. In particular, this thesis focuses on the change in interpretation which occurred between the 1951 decision in Dennis v. United States, and the 1957 decision in Yates v United States. Dennis upheld the constitutionality of the Smith Act, and upheld the convictions of eleven Communist Party of the United States of America (CPUSA) leaders. Yates overturned the convictions of a group of California CPUSA officials, and placed strict limitations on the use of the Smith Act in a drastic change in interpretation.  This thesis aims to explore that change in interpretation by drawing on three different lines of reasoning: the impact of changes to the wider Cold War context, the impact of changes to the personnel making up the Supreme Court, and changes in legal strategy on behalf of the defendants in the two cases. To achieve this, the thesis draws on a wide range of sources, beginning with a discussion of existing literature, and moving to explore previously untapped sources from both a historic and a legal perspective. This includes looking at the records of law firms acting in both cases, analysing other Supreme Court opinions from the time, and drawing on more traditional historical sources like media coverage of various events.  This thesis argues that, contrary to most existing scholarship, the change in interpretation is best explained by a multi-causal approach. The changes to the court’s makeup and changes to the context amongst which the cases occurred were only part of the reason for the change in interpretation. The impact of a change in legal strategy also played an important role in causing the Supreme Court’s change in interpretation.</p>
