Determination of molecular spectroscopic parameters and energy-transfer rates by double-resonance spectroscopy

The spectroscopy of small to medium-size polyatomic molecules can be extremely complex, especially in higher-lying overtone and combination vibrational levels. The high density of levels also complicates the understanding of inelastic collision processes, which is required to model energy transfer and collision broadening of spectral lines. Both of these problems can be addressed by double-resonance spectroscopy, i.e., time-resolved pump-probe measurements using microwave, infrared, near-infrared, and visible-wavelength sources. Information on excited-state spectroscopy, transition moments, inelastic energy transfer rates and propensity rules, and pressure-broadening parameters may be obtained from such experiments. Examples are given for several species of importance in planetary atmospheres, including ozone, silane, ethane, and ammonia

Diabetic retinopathy and socioeconomic deprivation in Gloucestershire

Objectives To investigate socioeconomic variations in diabetes prevalence, uptake of screening for diabetic retinopathy, and prevalence of diabetic retinopathy. Methods The County of Gloucestershire formed the setting of the study. A cross-sectional study of people with diabetes was done on a countywide retinopathy-screening database. Diabetes prevalence with odds ratios, uptake of screening, prevalence of any retinopathy and prevalence of sight-threatening retinopathy at screening were compared for different area deprivation quintiles. Logistic regression was used to adjust for confounding. Results With each increasing quintile of deprivation, diabetes prevalence increased (odds ratio 0.84), the probability of having been screened for diabetic retinopathy decreased (odds ratio 1.11), and the prevalence of sight-threatening diabetic retinopathy among screened patients increased (odds ratio of 0.98), while the prevalence of non-sight-threatening diabetic retinopathy remained unchanged with each increasing quintile of deprivation. Conclusion Sight-threatening diabetic retinopathy was associated with socioeconomic deprivation, but non-sight-threatening diabetic retinopathy was not. Uptake of screening was inversely related to socioeconomic deprivation

The case for intervention bias in the practice of medicine.

Bias is an inclination to present or hold a partial perspective at the expense of possibly equal or more valid alternatives. In this paper, we present a series of conditional arguments to prove that intervention bias exists in the practice of medicine. We then explore its potential causes, consequences, and criticisms. We use the term to describe the bias on the part of physicians and the medical community to intervene, whether it is with drugs, diagnostic tests, non-invasive procedures, or surgeries, when not intervening would be a reasonable alternative. The recognition of intervention bias in medicine is critically important given today\u27s emphasis on providing high-value care and reducing unnecessary and potentially harmful interventions

Homer Simpson Marches on Washington: Dissent through American Popular Culture

The Simpsons consistently questions what is culturally acceptable, going against the grain of popular culture by showcasing controversial issues like homosexuality, animal rights, the war on terror, and religion. This subtle form of political analysis is entertaining and great for television ratings, but it also can be an effective means of changing opinions and attitudes on a large scale. To consider another example, what does Star Trek teach viewers about feminist politics? Do comedy programs like The Daily Show and Saturday Night Live advance democracy in ways the mainstream news media cannot? Can horror films contribute to a contemporary understanding of environmentalism? Homer Simpson Marches on Washington: Dissent through American Popular Culture explores how popular culture influences political agendas, frames audience perceptions, and changes values and ideals on both the individual and collective level. Editors Timothy M. Dale and Joseph J. Foy have assembled a top-notch team of scholars from the fields of political science, history, women’s and minority studies, film and media studies, communication, music, and philosophy to investigate the full spectrum of popular culture in a democratic society. Homer Simpson Marches on Washington examines television shows such as Star Trek: The Next Generation, The X-Files, All in the Family, The View, and The Colbert Report, as well as movies and popular music, demonstrating how covert political and social messages affect the cultural conversation in America. The contributing authors investigate a wide range of controversial topics, including gender, race, religion, class, the environment, and sexual orientation. Kate Mulgrew, who played Captain Janeway in Star Trek: Voyager, offers her own story in the book’s foreword, describing the societal pressures of being the first female captain in the Star Trek franchise. In today’s fragmented society, audiences are met daily with thousands of messages competing for their attention. Homer Simpson Marches on Washington offers an entertaining and insightful look at how popular culture can break through the clutter and bring about profound changes. Timothy M. Dale, assistant professor of political science at the University of Wisconsin–Green Bay, is coauthor of Political Thinking, Political Theory, and Civil Society. Joseph J. Foy, assistant professor of political science at the University of Wisconsin–Waukesha, is the editor of Homer Simpson Goes to Washington: American Politics through Popular Culture. Popular culture is a growing area of interest, especially given its status as a major U.S. export in this rapidly globalizing world. Homer Simpson Marches on Washington is a useful and interesting work. --Margaret Ferguson, Indiana University–Purdue University Indianapolis Homer Simpson Marches on Washington is essential reading for anyone who believes that mass media can be effective in exposing the oppressive powers the be and inspiring people to resist them. --catapult magazine Both Homer Simpson Goes to Washington and Homer Simpson Marches on Washington look at popular culture as not simply entertainment of the masses. Instead, pop culture can emphasize contemporary societal norms, or introduce new ideas and social constructs....Pop culture reaches a national audience, and as such, is inspiring nationwide conversations about politics, race, marriage, religion, etc. If you want to learn more about the basis for these conversations, these two books are excellent resources. --Annette Aguayo, Voices From the Earthhttps://uknowledge.uky.edu/upk_american_popular_culture/1009/thumbnail.jp

Estimation of mercury emissions from forest fires, lakes, regional and local sources using measurements in Milwaukee and an inverse method

Gaseous elemental mercury is a global pollutant that can lead to serious health concerns via deposition to the biosphere and bio-accumulation in the food chain. Hourly measurements between June 2004 and May 2005 in an urban site (Milwaukee, WI) show elevated levels of mercury in the atmosphere with numerous short-lived peaks as well as longer-lived episodes. The measurements are analyzed with an inverse model to obtain information about mercury emissions. The model is based on high resolution meteorological simulations (WRF), hourly back-trajectories (WRF-FLEXPART) and a chemical transport model (CAMx). The hybrid formulation combining back-trajectories and Eulerian simulations is used to identify potential source regions as well as the impacts of forest fires and lake surface emissions. Uncertainty bounds are estimated using a bootstrap method on the inversions. Comparison with the US Environmental Protection Agency's National Emission Inventory (NEI) and Toxic Release Inventory (TRI) shows that emissions from coal-fired power plants are properly characterized, but emissions from local urban sources, waste incineration and metal processing could be significantly under-estimated. Emissions from the lake surface and from forest fires were found to have significant impacts on mercury levels in Milwaukee, and to be underestimated by a factor of two or more

Homer Simpson Ponders Politics: Popular Culture as Political Theory

It is often said that the poet Homer “educated” ancient Greece. Joseph J. Foy and Timothy M. Dale have assembled a team of notable scholars who argue, quite persuasively, that Homer Simpson and his ilk are educating America and offering insights into the social order and the human condition. Following Homer Simpson Goes to Washington (winner of the John G. Cawelti Award for Best Textbook or Primer on American and Popular Culture) and Homer Simpson Marches on Washington, this exceptional volume reveals how books like J. R. R. Tolkien’s The Hobbit and J. K. Rowling’s Harry Potter, movies like Avatar and Star Wars, and television shows like The Office and Firefly define Americans’ perceptions of society. The authors expand the discussion to explore the ways in which political theories play out in popular culture. Homer Simpson Ponders Politics includes a foreword by fantasy author Margaret Weis (coauthor/creator of the Dragonlance novels and game world) and is divided according to eras and themes in political thought: The first section explores civic virtue, applying the work of Plato and Aristotle to modern media. Part 2 draws on the philosophy of Hobbes, Locke, Rousseau, and Smith as a framework for understanding the role of the state. Part 3 explores the work of theorists such as Kant and Marx, and the final section investigates the ways in which movies and newer forms of electronic media either support or challenge the underlying assumptions of the democratic order. The result is an engaging read for undergraduate students as well as anyone interested in popular culture. Joseph J. Foy, associate campus dean and associate professor of political science at the University of Wisconsin–Waukesha, is the editor of Homer Simpson Goes to Washington: American Politics through Popular Culture and coeditor of Homer Simpson Marches on Washington: Dissent through American Popular Culture. Timothy M. Dale, assistant professor of political science at the University of Wisconsin–La Crosse, is coeditor of Homer Simpson Marches on Washington: Dissent through American Popular Culture. “Today, film, fiction, and television reflect our notions of civic virtue, morality, and the human condition—or at least help us to struggle with understanding and defining these. The ubiquitous nature of popular culture means that it will have an effect upon us, whether one likes that or not. The authors argue that, given this fact, even those who doubt the ‘seriousness’ of popular culture would do well to pay attention to it.”—Margaret Ferguson, Assistant Vice President for Statewide Academic Relations at Indiana University Since ancient times myths and stories have been used to convey our deepest thoughts about how to live together in community. With this book we now have a fun and engaging way to learn and think about political theory through the myths and stories of our time, popular culture. -- William Irwin, author of Black Sabbath and Philosophy: Mastering Reality Foy and Dale have done it again, this time with political theory! Political theory is one of the most difficult subjects that political science undergraduates encounter and Homer Simpson Ponders Politics opens up an avenue for students to engage many of the broad theories through some of the cultural artifacts with which they are most familiar: popular culture. These important theories bubble up through all areas of popular culture from Machiavelli and The Godfather to Plato and Star Wars— there is much to learn from this compendium. This is a useful book for students of political theory of any age or training and for those who are intrigued by the many political concepts popular culture teaches us. --Lilly J. Goren, coeditor of Women and the White House: Gender, Popular Culture, and Presidential Politics Most essays in this collection employ their philosophical guides in ways that can...disabuse undergraduates of the notion that political theory can better address the sterile and obsolete concerns of forgotten eras than fundamental questions about contemporary political life. -- Choicehttps://uknowledge.uky.edu/upk_american_popular_culture/1013/thumbnail.jp

How do hospitals respond to feedback about blood transfusion practice? A multiple case study investigation

National clinical audits play key roles in improving care and driving system-wide change. However, effects of audit and feedback depend upon both reach (e.g. relevant staff receiving the feedback) and response (e.g. staff regulating their behaviour accordingly). This study aimed to investigate which hospital staff initially receive feedback and formulate a response, how feedback is disseminated within hospitals, and how responses are enacted (including barriers and enablers to enactment). Using a multiple case study approach, we purposively sampled four UK hospitals for variation in infrastructure and resources. We conducted semi-structured interviews with staff from transfusion-related roles and observed Hospital Transfusion Committee meetings. Interviews and analysis were based on the Theoretical Domains Framework of behaviour change. We coded interview transcripts into theoretical domains, then inductively identified themes within each domain to identify barriers and enablers. We also analysed data to identify which staff currently receive feedback and how dissemination is managed within the hospital. Members of the hospital’s transfusion team initially received feedback in all cases, and were primarily responsible for disseminating and responding, facilitated through the Hospital Transfusion Committee. At each hospital, key individuals involved in prescribing transfusions reported never having received feedback from a national audit. Whether audits were discussed and actions explicitly agreed in Committee meetings varied between hospitals. Key enablers of action across all cases included clear lines of responsibility and strategies to remind staff about recommendations. Barriers included difficulties disseminating to relevant staff and needing to amend feedback to make it appropriate for local use. Appropriate responses by hospital staff to feedback about blood transfusion practice depend upon supportive infrastructures and role clarity. Hospitals could benefit from support to disseminate feedback systematically, particularly to frontline staff involved in the behaviours being audited, and practical tools to support strategic decision-making (e.g. action-planning around local response to feedback)
