  • Some mosquitoes like it hot

    Some mosquitoes like it hot

    [ad_1]

    Newswise — Certain populations of mosquitoes are more heat tolerant and better equipped to survive heat waves than others, according to new research from Washington University in St. Louis.

    This is bad news in a world where vector-borne diseases are an increasingly global health concern. Most models that scientists use to estimate vector-borne disease risk currently assume that mosquito heat tolerances do not vary. As a result, these models may underestimate mosquitoes’ ability to spread diseases in a warming world.

    Researchers led by Katie M. Westby, a senior scientist at Tyson Research Center, Washington University’s environmental field station, conducted a new study that measured the critical thermal maximum (CTmax), an organism’s upper thermal tolerance limit, of eight populations of the globally invasive tiger mosquito, Aedes albopictus. The tiger mosquito is a known vector for many viruses including West Nile, chikungunya and dengue.

    “We found significant differences across populations for both adults and larvae, and these differences were more pronounced for adults,” Westby said. The new study is published Jan. 8 in Frontiers in Ecology and Evolution.

    Westby’s team sampled mosquitoes from eight different populations spanning four climate zones across the eastern United States, including mosquitoes from locations in New Orleans; St. Augustine, Fla.; Huntsville, Ala.; Stillwater, Okla.; St. Louis; Urbana, Ill.; College Park, Md.; and Allegheny County, Pa.

    The scientists collected eggs in the wild and raised larvae from the different geographic locations to adult stages in the lab, tending the mosquito populations separately as they continued to breed and grow. The scientists then used adults and larvae from subsequent generations of these captive-raised mosquitoes in trials to determine CTmax values, ramping up air and water temperatures at a rate of 1 degree Celsius per minute using established research protocols.

    The team then tested the relationship between climatic variables measured near each population source and the CTmax of adults and larvae. The scientists found significant differences among the mosquito populations.

    The differences did not appear to follow a simple latitudinal or temperature-dependent pattern, but there were some important trends. Mosquito populations from locations with higher precipitation had higher CTmax values. Overall, the results reveal that mean and maximum seasonal temperatures, relative humidity and annual precipitation may all be important climatic factors in determining CTmax.

    “Larvae had significantly higher thermal limits than adults, and this likely results from different selection pressures for terrestrial adults and aquatic larvae,” said Benjamin Orlinick, first author of the paper and a former undergraduate research fellow at Tyson Research Center. “It appears that adult Ae. albopictus are experiencing temperatures closer to their CTmax than larvae, possibly explaining why there are more differences among adult populations.”

    “The overall trend is for increased heat tolerance with increasing precipitation,” Westby said. “It could be that wetter climates allow mosquitoes to endure hotter temperatures due to decreases in desiccation, as humidity and temperature are known to interact and influence mosquito survival.”

    Little is known about how different vector populations, like those of this kind of mosquito, are adapted to their local climate, nor the potential for vectors to adapt to a rapidly changing climate. This study is one of the few to consider the upper limits of survivability in high temperatures — akin to heat waves — as opposed to the limits imposed by cold winters.

    “Standing genetic variation in heat tolerance is necessary for organisms to adapt to higher temperatures,” Westby said. “That’s why it was important for us to experimentally determine if this mosquito exhibits variation before we can begin to test how, or if, it will adapt to a warmer world.”

    Future research in the lab aims to determine the upper limits that mosquitoes will seek out hosts for blood meals in the field, where they spend the hottest parts of the day when temperatures get above those thresholds, and if they are already adapting to higher temperatures. “Determining this is key to understanding how climate change will impact disease transmission in the real world,” Westby said. “Mosquitoes in the wild experience fluctuating daily temperatures and humidity that we cannot fully replicate in the lab.”

  • Psychological science can help counter spread of misinformation, says APA report

    Psychological science can help counter spread of misinformation, says APA report

    [ad_1]

    Newswise — WASHINGTON – Debunking, “prebunking,” nudging and teaching digital literacy are several of the more effective ways to counter misinformation, according to a new report from the American Psychological Association.

    Written by a panel of U.S. and international experts on the psychology of misinformation, the report outlines the processes that make people susceptible to misinformation and offers solutions to combat it.

    People are more likely to believe misinformation if it comes from groups they belong to or if they judge the source as credible, according to the report “Using Psychological Science to Understand and Fight Health Misinformation: An APA Consensus Statement.” It defines misinformation as “any information that is demonstrably false or otherwise misleading, regardless of its source or intention.”

    The report outlines the key features of misinformation that fool people into believing and spreading it. For instance, it found that people are more likely to believe false statements that appeal to emotions such as fear and outrage. They are also more likely to believe misinformation that paints groups that they view as “others” in a negative light. And people are more likely to believe information the more it is repeated, even when it contradicts their prior knowledge. These findings suggest that it is important to stop misinformation early, the report says.

    The report also describes features of social media that help misinformation spread very quickly. “Rapid publication and peer-to-peer sharing allow ordinary users to distribute information quickly to large audiences, so misinformation can be policed only after the fact (if at all),” the report says. “’Echo chambers’ bind and isolate online communities with similar views, which aids the spread of falsehoods and impedes the spread of factual corrections.” 

    As a result, “most online misinformation originates from a small minority of ‘superspreaders,’ but social media amplifies their reach and influence.”

    There are two levels on which misinformation can be stopped, according to the report: systemic approaches, such as legislation and technology standards, and individual approaches focused on changing individual behaviors. The latter include: 

    • fact-checking, or debunking; 
    • prebunking, or pre-emptive debunking to prevent people from falling for misinformation in the first place; 
    • nudges, such as asking people to consider the accuracy of information before sharing it, or rewarding people to be as accurate as possible; 
    • and formal education or community outreach to raise people’s awareness about healthy online behavior and media use.

    The report acknowledges that there is much more to learn and recommends more research funding and industry cooperation to understand behaviors related to misinformation and create tools to correct it. The panel members who wrote the report spent more than a year reviewing the scientific literature to develop their recommendations. The report was commissioned by the Centers for Disease Control and Prevention and funded as part of a $2 million grant to develop effective solutions to COVID-19 vaccine hesitancy. 

    While the panel’s recommendations focus on health misinformation, they can also be used for broader topics such as politics and climate change. For instance, these findings offer direct input to one of the main issues highlighted in APA’s Health Advisory on Social Media by addressing tactics that can be used to combat misinformation.  

    The report recommends eight steps for policymakers, scientists, media and the public to help curb the spread of misinformation and the risks it poses to health, well-being and civic life: 

    1. Avoid repeating misinformation without including a correction.
    2. Collaborate with social media companies to understand and reduce the spread of harmful misinformation.
    3. Use misinformation correction strategies with tools already proven to promote healthy behaviors.
    4. Leverage trusted sources to counter misinformation and provide accurate health information.
    5. Debunk misinformation often and repeatedly using evidence-based methods.
    6. Prebunk misinformation to inoculate susceptible audiences by building skills and resilience from an early age.
    7. Demand data access and transparency from social media companies for scientific research on misinformation.
    8. Fund basic and translational research into the psychology of health misinformation, including ways to counter it.

    “These psychological science findings help to explain how misinformation enters our thought processes,” the report states. “It is effortful and difficult for our brains to apply existing knowledge when encountering new information; when new claims are false but sufficiently reasonable, we can learn them as facts. Thus, everyone is susceptible to misinformation to some degree: we acquire it even when we know better.”

     

    The American Psychological Association, in Washington, D.C., is the largest scientific and professional organization representing psychology in the United States. APA’s membership includes over 146,000 researchers, educators, clinicians, consultants and students. Through its divisions in 54 subfields of psychology and affiliations with 60 state, territorial and Canadian provincial associations, APA works to advance the creation, communication and application of psychological knowledge to benefit society and improve people’s lives.

  • Music plagiarism detection: algorithms vs. human judgment

    Music plagiarism detection: algorithms vs. human judgment

    [ad_1]

    Newswise — Ed Sheeran convinced a jury this year that he didn’t rip off Marvin Gaye’s `Let’s Get It On.’ By way of contrast, Pharrell Williams and Robin Thicke earlier failed to establish that `Blurred Lines’ wasn’t a copy of Gaye’s `Got to Give It Up.’

    Could automated algorithms bring a new objectivity to music copyright infringement decisions, limiting the number, scale and expense of court cases?

    Musicologist Dr Patrick Savage of the University of Auckland researched the topic in collaboration with Yuchen Yuan of Keio University, Japan, and experts in music psychology and copyright law from Goldsmiths, University of London, and George Washington University in the US.

    “It’s the largest study so far of how the best algorithms compare with humans in judging when music crosses the line into plagiarism,” says Savage, a senior research fellow in the University’s School of Psychology. “It’s fair to say that algorithms won’t be taking over any time soon.”

    Savage’s involvement in the area has included contributing to an amicus curiae brief – that’s expert evidence for a court – that helped overturn a decision in a Katy Perry case.

    In the study, 51 people were asked to judge 40 examples of alleged plagiarism from 1915 to 2018, including a New Zealand National Party Eminem-style campaign advertisement from 2014 and ex-Beatle George Harrison’s ‘My Sweet Lord’ from the 1970s.

    Algorithms PMI and Musly, two of the best publicly available tools for discovering music plagiarism, assessed the same songs.

    Study participants’ assessments matched the court decisions in as much as 83 percent of the cases (33 out of 40 ) versus 75 percent for the algorithms (30 out of 40).

    One limitation of the study is the underlying assumption that the court cases were decided correctly.

    “The `Blurred Lines’ case caused considerable controversy – and neither our study participants nor the algorithms strongly supported the legal decision – nor did many musicians, musicologists, lawyers, or judges, for that matter,” says Savage.

    One permanent limitation on using algorithms to decide copyright cases is that non-musical factors can play a role.

    “For example, regardless of how similar two songs are, there won’t be a breach of copyright if the allegedly plagiarising composer can show that it would have been impossible for them to have heard the earlier song,” he says.

    Ultimately, trial by algorithm won’t replace trial by jury, but algorithms’ objective assessments may be a factor to take into consideration.

    “For example, Spotify is already experimenting with a Plagiarism Risk Detector that might help artists automatically catch unintended similarities with existing works before they release new songs,” says Savage. “Future court cases might also be able to include graphs of how similar two songs are in relation to past cases to give judges and juries more objective data and context to aid their decisions.”

    As litigation becomes more frequent, “unjustified music copyright lawsuits not only inhibit music creativity but also waste millions of taxpayer dollars annually to cover the adjudication of these disputes,” Savage and his co-authors wrote in the paper, published in the journal Transactions of the International Society for Music Information Retrieval.

    The algorithm Percent Melodic Identity was invented by Savage and fellow School of Psychology academic Professor Quentin Atkinson to study the evolution of folk song melodies.

    Musly, invented by Dr Dominik Schnitzer from the Austrian Research Institute for Artificial Intelligence, includes features like rhythm and timbre in addition to melody.

  • FSU Agatha Christie expert available to speak on author’s important and lasting impact on the world and in modern media

    FSU Agatha Christie expert available to speak on author’s important and lasting impact on the world and in modern media

    [ad_1]

    By: Jenny Ralph | Published: | 3:55 pm 

    Even half a century after penning her final novel, Agatha Christie and her Golden Age crime stories still endure in contemporary media.

    In fact, the newly released film, “A Haunting in Venice,” is based on Christie’s 1969 novel “Hallowe’en Party.” With more than 66 detective novels and 14 short story collections published, the Queen of Crime has proven that her murder mysteries continue to have people asking more than “Who done it?”

    Michelle Kazmer, dean of Florida State University’s College of Communication and Information and professor in the School of Information, discovered Christie’s work in her public library when she was just 12 years old.

    “Most of the things we think of as typical tropes in detective fiction, Agatha either did it first or did it best,” Kazmer said. “She is eminently readable and re-readable, and her work has been translated into more than 100 languages and adapted into every communication and entertainment medium from stage plays to video games. New audiences are continually discovering and loving her work.”

    Now, Kazmer is a leading expert on how Christie uses information theories in her stories.

    “Detection is an information behavior,” she said. “You are seeking information, figuring out what to keep and what to get rid of, organizing what you keep, and then drawing a conclusion. In the case of these stories, the detectives use information to determine who committed the crime and why.”

    But she also explores other aspects of Christie and crime fiction’s lasting impact on society.

    “People’s views of crime, policing, justice, morality and ethics are all deeply shaped by their consumption of crime fiction — whether it’s books, TV, movies or even podcasts,” Kazmer said. “Crime fiction has a real material effect on the world as we experience it.”

    Crime fiction publishing overall has a large economic impact as a multibillion-dollar industry, and Christie’s books continue to sell in the multi-millions annually.

    Kazmer is available to provide insight into how and why Christie and her stories have such a lasting impact on society.

    Michelle Kazmer is a leading American researcher in applying theories on information to Golden Age crime fiction and aligns with the community of Agathologists who study the work of Agatha Christie. She has contributed the chapter “Christie’s Clues as Information” to “The Bloomsbury Handbook to Agatha Christie,” been interviewed by the BBC on the topic twice and co-hosted an episode of the All About Agatha Podcast. Most recently, she was the first American to give the keynote speech at the Agatha Christie and Golden Age of Crime international conference.

  • The truth is out there. This astrophysicist is helping to find it using science

    The truth is out there. This astrophysicist is helping to find it using science

    [ad_1]

    Newswise — Capture good, useful data and University of Delaware astrophysicist Federica Bianco will dig deep to help analyze it. It’s what she does with great expertise as a scientist and associate professor of physics and astronomy and it’s a big reason why she was among the 16 people selected to serve on a NASA-appointed panel studying Unidentified Anomalous Phenomena (UAP).

    UAP is the official term now applied to what many used to call Unidentified Flying Objects (UFOs), things spotted in the sky that could not be correlated with an airplane, satellite or some other known aerial phenomenon. The new term includes all manner of anomalous phenomena — whether detected in the air, in space, even under the ocean.

    NASA says UAP are of interest for reasons including national security and air safety. Access to extensive data sets are required to verify or explain observations and the panel has focused on what data could be collected to scientifically discern the nature of UAP.  

    But there has been precious little useful data to go on, as the panel reported in its four-hour publicly accessible meeting on May 31. Now the panel has released its final report.

    During a media briefing on Thursday, Sept. 14, astrophysicist David Spergel, who chaired the independent study panel, was clear.

    “It is essential to clarify that we find no evidence that UAP are extraterrestrial in origin,” he said. “Most events are explainable as planes, balloons, drones or weather phenomena.”

    A small fraction of reports are anomalous, however. So far, for lack of adequate data, scientists cannot explain them.

    “If you see something, collect high-quality data on it,” Spergel said. “Then we can learn.”

    Theories and conspiracy theories often swirl after reported sightings of such anomalies. Images captured on smart phones or other video devices can be impressive and even seem persuasive at a glance.

    Scientists, though, rely on data and bring careful, rigorous processes to the questions they consider.

    “There’s a lot of folklore out there,” said NASA Administrator Bill Nelson. “We want to shift from sensationalism to science.”

    To that end, NASA now has appointed a director of UAP Research, said Nicola Fox, the head of NASA’s Science Mission Directorate.

    Bianco brought high-level data analysis skills and expertise in astrophysics to the interdisciplinary panel, which also included other experts in the scientific, aeronautics and data analytics communities.

    “The reports we have cannot be studied scientifically,” Bianco said. “That’s not a dismissal of people’s experiences. It just doesn’t rise to the level of evidence of extraordinary phenomena. If people see things in the sky that they can’t explain, that doesn’t mean there was a phenomenon in the sky. But with the capabilities they have for observation, it is not explainable by anything they know.”

    This is exactly what astrophysicists investigate, she said. If someone says they saw something in the sky that was brightening up and then dimming and they think it must be a new kind of star, she will have a lot of questions.

    “If they come to me and tell me what they saw, first I want to go and measure it quantitatively,” Bianco said. “Where is it? How much does it brighten? What is the color that tells me about the physics? Are these characteristics something I’ve never seen? Is it something the person has perceived correctly?”

    The questions examined by the panel certainly fall within NASA’s wheelhouse. Exploring space and the atmosphere is central to all NASA does. And while NASA is always looking for signs of life elsewhere in the universe, it does not actively search for UAPs. NASA has said it has found no credible evidence of extraterrestrial life and there is no evidence that UAPs are extraterrestrial.

    The UAP study panel was led by Spergel, president of the Simons Foundation in New York City and previously the chair of the astrophysics department at Princeton University in Princeton, New Jersey. Daniel Evans, assistant deputy associate administrator for research at NASA’s Science Mission Directorate, served as the NASA official responsible for orchestrating the study.

    Bianco has known Spergel for several years and was glad to join the study.

    “I like interdisciplinary groups and the composition of the panel was so intriguing,” she said. “And aliens, right? That’s an interesting thing to think about and to work on. So yeah, I didn’t hesitate much before agreeing to that.”

    Public interest has been high, too. And recent Congressional hearings have drawn more attention to the issue of UAPs. Some interest has carried sharp political barbs, with accusations that NASA and several U.S. government agencies are hiding important evidence of extraterrestrial life, including recovered parts of alien spacecraft and even live aliens themselves.

    “Really, none of the eyewitness testimony — even those by the military that we have seen — has associated data that is of good enough quality,” Bianco said. “If the videos were shot by people’s phones, what were the lighting conditions? How sensitive is the instrument? If you cannot say these things, you cannot know quantitatively. When we were able to do that — in a couple of observations with multiple sensors — in fact, the characteristics were not unique.”

    The data available now are mostly of limited value.

    “The current status of data is inconsistent, largely incomplete and not systematically retrievable,” she said during the panel broadcast on May 31. “That causes problems in the automation of analysis. Machine learning and artificial intelligence cannot be applied until the data meets that standard. Organized repositories are needed.”

    In addition, the data must be collected by calibrated sensors, with information about the brands, characteristics, instrument sensitivity, circumstances, locations and the condition of the sensors. At the time of data collection, she said.

    Bianco finds the quest for useful data essential, but recognizes that not everyone agrees with the need for facts. Some will never accept that their beliefs, based on something other than sound data, may be incorrect.

    “I could spend my life trying to convince some people — and they are clearly not my target audience,” she said.

    Those who think the scientists on the panel are there simply to give plausibility to a greater government cover-up may not really understand the scientist’s quest for knowledge and disseminating that knowledge.

    “As a scientist, if I find evidence of extraterrestrial life, I have not only an obligation to publish the findings but — while there is no board that requires it — spiritually, I have taken an oath to adhere to the truth and propagate the truth that I find. That’s my job,” she said.

    “I don’t work for the government. I understand the government may have security issues that I don’t understand. But I’m a scientist. If this panel showed me evidence of extraterrestrial life, I’d be writing about it.”

    Among Bianco’s suggestions is a crowd-sourcing application that allows people to submit data about things they have seen and allows others to examine and assess that data. It could include camera information, audio, pixels, resolutions, sensitivity of the instrument and the wavelengths it captures.

    “Part of the problem is that if you really want to look at this data in context, you need all of this information,” she said. “One gets a blurry picture, another gets a sound recording and another gets a photo but doesn’t know why the colors look the way they look.”

    Crowd-sourcing projects have their own set of challenges, but she sees potential value for those who want to understand and participate in the quest in some way.

    “You have three types of audiences — people who care, people who don’t care enough to do the work or be active, but can listen to you, and people who are adversarial,” she said. “It might be more satisfying to fight a battle with the adversarial, but it’s not most productive. There are people who have completely bought into the idea that NASA is hiding aliens and is part of some dark forces that sell a lie for reasons I don’t know. That’s not my audience, but they are kind of dominating the discussion.”

    She likes the idea of an app that gives people information about things that exist in the sky and allows them to submit data from their own devices.

    “It could help people become part of this conversation,” she said. “It would help us communicate the understanding we have and what the process looks like.”

    Panelists talked with many agencies to explore the way they collect data, curate data and retain data.

    The Federal Aviation Administration, for example, can tell you that about 880,000 small drones are registered in the United States and thousands are operated on a daily basis. Almost 100 weather stations release balloons on a daily basis, with requirements on how they report timing and tracking data.

    While some may be convinced that what they saw must have been extraterrestrial, scientists don’t start there.

    “I can’t just take your word,” she said. “That’s not how we make decisions. We make decisions based — traditionally and aspirationally — on evidence and fact, not the hunches and feelings of individuals.

    “We have to start from the skeptical point of view. We take the scientific approach, where I first falsify the most unusual explanation and try to explain things in ways that are usual. We have hypotheses and we rule them out. What is left is what we currently believe. Our current understanding of the physical world comes from ruling things out until the things we have found no longer fit the better data that we now have.”

    Any alternate route should be considered with great skepticism.

    “If you’re trying to actively collect exceptional and specific pieces of evidence that support your ideas but don’t look at the larger context, you are trying to make a name for yourself,” she said. “That is not the correct scientific approach…. I would not have been on that panel.”

    Among Bianco’s research interests are technosignatures, which are defined as any detectable sign of extant or extinct life. They are part of UAP studies because they are a sign of technology that can be used to infer the existence of civilizations elsewhere in the universe —including large orbiting structures, atmospheric pollution, narrow-band radio signals or pulsed lasers.

    The panelists started their work on Oct. 24, 2022. All panelists had to submit financial disclosures and have a comprehensive government ethics briefing. Each was appointed in accordance with the Federal Advisory Committee Act, ensuring independent and objective advice.

    With its final report, the panel now has mapped out how data gathered by civilian government entities, commercial data and data from other sources can potentially be analyzed to shed light on UAPs. The study focused solely on unclassified data. 

    About the researcher

    Public Companies Info Boosted by Local News

    [ad_1]

    Newswise — Accounting researchers at the University of Arkansas are deepening their understanding of the effect of shrinking newsrooms on the financial information of public companies.

    A new study, to be published in Review of Accounting Studies, shows that local newspaper coverage significantly improved the general information about public companies, as measured by lower stock volatility and more accurate forecasts by financial analysts. Conversely, when local newspaper coverage declined, stock volatility, information asymmetry and illiquidity increased, the researchers found.

    A sign of stock stability, information asymmetry refers to the difference or gap between two parties in their knowledge of relevant factors and details about companies’ value. Illiquidity simply means a security or asset that cannot be exchanged for cash or sold easily.   

    “Employment at newspapers has declined more than 75% since 2000,” said Caleb Rawson, assistant professor of accounting in the Sam M. Walton College of Business. “Researchers in other fields have already shown how this has a negative impact on local government, in terms of transparency and accountability of elected officials. We’re finding the same is true for businesses and public companies. These changes – that is, the decrease in local newsroom employment – have had a detrimental effect on the information environment of local firms.”

    Using data from the Bureau of Labor Statistics, Rawson and co-authors Kris Allee, professor of accounting at the U of A,, and Ryan Cating, assistant professor of accounting at the University of Central Arkansas and a U of A doctoral alumnus in accounting, measured the level of local news intensity in each city (technically, each metropolitan statistical area, or MSA) as the percent of local jobs in the newspaper publishing industry. They compared this data to key indicators of firms’ financial information.

    The researchers found that the above effect – reduced news intensity leading to less or poorer quality of information – was exacerbated when a given firm was more important to the local economy. For these firms, less local newspaper intensity was associated with significantly lower analyst accuracy and fewer, or more dispersed, forecasts.

    Rawson and his colleagues also investigated how stakeholders respond to declines in local news coverage of firms. Firm managers increased the number of forward-looking financial disclosures and analysts increased their own coverage. Following decreases in newspaper employment, investors increased their own data-gathering activities as well.

    “We think these results provide insights into the methods by which stakeholders attempt to improve firms’ information environments when local news coverage fades and highlight the important role that local newspapers play in the economy,” Rawson said.

    Allee is the Doyle Z. Williams Chair of the Walton College’s Department of Accounting.

    Immigration experts on Title 42, analysis of immigration policies, and other migrant news in the Immigration Channel

    [ad_1]

    Title 42, the United States pandemic rule that had been used to immediately deport hundreds of thousands of migrants who crossed the border illegally over the last three years, has expired. Those migrants will have the opportunity to apply for asylum. President Biden’s new rules to replace Title 42 are facing legal challenges. The US Homeland Security Department announced a rule to make it extremely difficult for anyone who travels through another country, like Mexico, to qualify for asylum. Border crossings have already risen sharply, as many migrants attempted to cross before the measure expired on Thursday night. Some have said they worry about tighter controls and uncertainty ahead. Immigration is once again a major focus of the media as we examine the humanitarian, political, and public health issues migrants must face.

  • Hollywood writers strike: AI concerns, industry consequences

    Hollywood writers strike: AI concerns, industry consequences

    [ad_1]

    Hollywood screenwriters have gone on strike. The Writers Guild of America (WGA) seeks higher pay, upfront fees from streaming services, better working conditions and reassurance that studios won’t use artificial intelligence programs to generate scripts. The last WGA strike, 15 years ago, led to permanent changes in the entertainment landscape, such as the rise of reality television. Effects from the newest work stoppage have already begun, and the longer the strike continues, the more consequences it will have.

    Virginia Tech communications law expert Cayce Myers offers his perspective on the writers’ concerns about use of AI in screenwriting, and  Virginia Tech media technology expert James Ivory discusses the strike’s potential ramifications for the television and film industries.

    Cayce Myers on the use of AI to write scripts

    “The members of the WGA are essentially afraid of being replaced with AI,” Myers said. “Because of the rapid development of the technology, screenwriters fear that without regulations on AI they as an industry could cease to exist with few, if any, consequences for entertainment companies. Generative AI has the ability to mimic the writing of famous writers, dead and alive, so it is possible to have new scripts sounding like they were written by famed screenwriters.”  

    “The underlying conflict of automation vs. workers is nothing new. The difference here is that creative work has never been threatened so much by new technology. There’s also the legal issues of copyright and appropriation, which is complicated by the fact that generative AI content fails the originality requirement for copyright,” Myers said. “It’s important to see how this turns out in negotiation. As more people figure out the power of this new technology, there will be a greater public demand for its regulation. The parameters on generative AI use that result from WGA negotiations may serve as a guidepost for other regulations of the technology.”

    James Ivory on strike consequences for entertainment industry

    “Your favorite talk show host is already going without jokes on current events as of today, and you will notice the difference. Many on-camera hosts and actors will likely acknowledge the strike, partly to explain the absence of writing but also in support of the writers,” Ivory said. “Films and television programs with longer production cycles are also immediately affected, but audiences won’t see the impact on these programs for some time as most television series and movies airing now were written long ago.”

    “We will likely see impacts on other programming decisions if the strike is a long one, which will affect not only what audiences see, but also the employment of others in the television and film industry,” Ivory said. “Planned and ongoing projects may be canceled, postponed, and revived due to the writers’ strike. In the past, strikes have led to more reality television programming being kept and introduced as a substitute for more writing-intensive programming.”

    “The biggest impact of the strike, of course, is on the writers,” Ivory said. “The conditions of the strike heavily limit the work they can do. It is a scary time for a lot of people in an industry that has already been hit very hard by the COVID-19 pandemic. The last writers’ strike in 2007-2008 lasted 100 days. That’s a long time to wait for a paycheck.”

  • ISPOR Marks 25th Anniversary of Flagship Journal Value in Health

    ISPOR Marks 25th Anniversary of Flagship Journal Value in Health

    [ad_1]

    Newswise — Lawrenceville, NJ, USA—May 2, 2022—Value in Health, the official journal of ISPOR—The Professional Society for Health Economics and Outcomes Research (HEOR), published an editorial celebrating its 25th anniversary as the Society’s flagship HEOR journal. The article, “25 Years of Health Economics and Outcomes Research: An Exploration of Value in Health,” appears in the May 2023 issue of Value in Health.

    In 1998, the inaugural Editor-in-Chief laid out a vision for Value in Health to serve as a forum where consensus can be built around development of guidelines for conducting and reporting research in the field. In their editorial, the current Editors-in-Chief, Michael F. Drummond, MCom, DPhil, University of York, York, England, UK, and C. Daniel Mullins, PhD, University of Maryland Baltimore, Baltimore, MD, USA, examine to what extent the content published in Value in Health has contributed to achieving this goal.

    “We mark the 25th anniversary of the journal by examining the changes in the growth and composition of the literature and highlighting some of the key articles from the 25 top-cited items that the journal has published to date,” said Drummond and Mullins. The number of articles published has increased from 58 per year in the period from 1998-2010, to 196 per year in the period 2019-2022. In recent years, the most rapidly growing groups of papers have been those featuring methodological issues, health policy analyses, and systematic literature reviews. Another important change has been the publication of collections of papers in themed sections.

    In addition, since 2011 the journal has published more than 60 ISPOR Reports. These are papers written by official ISPOR member groups and are predominantly Good Practices Reports discussing methodological issues in HEOR. Good Practices Reports have been published in all the major topic areas in the journal’s scope, and many of them are among the top 25 most cited items.

    “When considering the top-cited items as a group, it does seem that a major focus of Value in Health has been on improving the conduct and reporting of HEOR studies and on developing good practice guidelines, consistent with the goal set by the founding editors of the journal,” said Drummond and Mullins. Based on its rich 25-year history, it may come as no surprise that Value in Health has emerged as one of the top-ranked journals in the HEOR field. Value in Health has been indexed in MEDLINE since 2001 when the original impact factor was 2.342. The journal’s most recent impact factor is 5.156, demonstrating the major impact Value in Health has had on the field of health economics and outcomes research.

    “As the journal’s current Editors-in-Chief, we are committed to continuing to advance HEOR science and methods,” said Drummond and Mullins. “At the same time, we hope that the advancement in scientific rigor will also motivate even greater acceptance by payers, prescribers, and policy makers of those HEOR articles that apply best practices of HEOR methods to address real-world decision making by payers, prescribers, and policy makers. In turn, this will influence which evidence-based drugs and health technologies are accessed by patients and the public. As that occurs, both Value in Health and the field of HEOR will achieve the potential of improving global public health, extending life, and improving health-related quality of life.”

  • Study warns of underestimated uncertainty in published research

    Study warns of underestimated uncertainty in published research

    [ad_1]

    Newswise — New research involving the University of Sydney Business School has found researchers underestimate the degree of uncertainty in their findings.

    In empirical science, researchers analyse samples to test hypotheses, and this creates a within-researcher variation due to sampling error. Re-sampling yields different values of the estimator, and the standard deviation of this distribution is referred to as standard error.

    Researchers are less aware, however, that there is an additional level of uncertainty due to there not being a standard analysis path.

    Researchers vary in what they deem to be the most reasonable path, and estimates may vary across researchers as they might pick different paths. This is referred to a non-standard error.

    The study, led by Professor Albert Menkveld at the Vrije University of Amsterdam and nine other academics, involved 164 teams testing the same hypotheses on the same data to measure the impact of non-standard errors.

    A separate team of highly experienced researchers was engaged to peer review the work of each of the 164 teams.

    The research, to be published in the Journal of Finance, found that such non-standard errors were substantial and similar in magnitude to standard errors.

    A relatively straightforward hypotheses about market share produced a non-standard error rate of 1.2 percent. For a more complex hypothesis about market efficiency, the non-standard error rate was up at 6.7 percent.

    Non-standard errors were smaller for better reproducible or higher-rated research, and slashed in half by adding peer-review stage.

    Study participant Professor Joakim Westerholm from the University of Sydney Business School said the research highlights the importance of researchers taking into account the potential dispersion in estimates when testing hypotheses due to the researchers’ choice of analysis path.

    “If researchers are not aligned on key decisions, such as selecting a statistical model or treating outliers, their estimates are likely to differ – adding uncertainty to the estimate reported by a single team,” Professor Westerholm said.

    “This type of uncertainty is often underestimated by researchers, which is why we need to be aware of our own bias and the steps we can take to minimise its impact.

    “While we cannot expect every question to be investigated by a team of 160 seasoned research teams, we can design approaches that take non-standard errors into account – for example, each member of a team could perform independent tests that are then compared and evaluated.”

    Professor Westerholm said the next stage in the research may be to replicate the study using artificial intelligence and machine learning to see whether this has any impact on the rate of non-standard errors.

  • Fox News settlement will do little to change perceived credibility of coverage, expert says

    Fox News settlement will do little to change perceived credibility of coverage, expert says

    [ad_1]

    The most anticipated media trial in recent years ended with a $787.5 million settlement, and while it had the opportunity to set the tone for future defamation litigation, Virginia Tech media expert Megan Duncan says the outcome will have little impact on the perceived credibility of Fox News.  

    “Few people are willing to reassess their perceptions of the credibility of Fox News — whether they side with the news organization or believe it was in the wrong — because politically active people associate partisan news brands with their political identity,” Duncan says. She explains that most partisans in the U.S. had long ago made up their minds about whether Fox News was a credible news source.  

    Dominion had been seeking $1.6 billion in damages. The company argued that its business had been hurt by 2020 election conspiracy theories advanced on Fox shows even though hosts, producers, and executives at the network knew they were false.

    “The size of this settlement and rulings by the judge before jury selection that Fox News had published falsehoods about Dominion Voting Systems will remain in the headlines ,” Duncan says. “That scrutiny, coupled with the public pre-trial evidence has the potential to move the needle of perceived credibility for the small portion of people who were ambivalent and hadn’t made up their minds about the claims.”

    Duncan points out that Fox News is the most-watched cable news network. Even still, it reaches only about 18 percent of the U.S. in the average month, according to Pew Research Center. Far more people — about half — are watching their local television news, which enjoys high levels of news trust. “Tuning into credible, ethical news increases local engagement and participation in democracy and audiences should hold the news they watch to high standards of verification and accuracy,” Duncan explains.

    To people who already thought Fox News  was acting unethically, Duncan says this settlement is more in evidence. To loyal Fox News audiences, she says they might reason this was just a quicker resolution to bogus claims. “Past research finds that corrections and fact-checks on incorrect information only moves opinions a little and that the false information can “echo” across time.” That means while an audience member knows the original information was found to be false, that person still takes into account the false information in future decision making. “To the extent that this settlement can be seen as a correction, I imagine the original claims made by Fox News will linger in the audience’s memory for years to come,” Duncan says.

    About Duncan

    Megan Duncan is an assistant professor in the School of Communication at Virginia Tech. Her research focuses on how partisans judge the credibility of and engage with the news. Using survey-embedded experiments, surveys, and other quantitative methods, she’s interested in knowing more about audiences, their perceptions of the news, how they form opinions, and how to use this knowledge to make democracy stronger.

  • Social media expert gives bird’s-eye view on Twitter spat with NPR, PBS

    Social media expert gives bird’s-eye view on Twitter spat with NPR, PBS

    [ad_1]

    The decision of social media platform Twitter under ownership of tech mogul Elon Musk to label National Public Radio and the Public Broadcasting Service as “U.S. state-affiliated media” caused the prominent news outlets to respond by ending use of Twitter. This conflict is the latest in an escalating series of conflicts between Musk and media outlets of multiple stripes.

    Mike Horning, an associate professor of multimedia journalism at Virginia Tech’s School of Communication, provides perspective on Twitter’s increasingly volatile relationship with news organizations and the advantages and disadvantages of Musk’s approach.

    Q: Twitter has for years been journalists’ social media platform of choice. Why would Elon Musk push back against this?

    “Since purchasing Twitter, Musk has tried to position himself as the antidote for a tech industry that he believes has been oppressive to both certain forms of speech and certain political views. He sees the media as complicit in supporting those dominant ideologies that are favored by social media companies, so it is not surprising to see him antagonize those forms of media that he feels have not objectively reported news.”

    Q: How might this affect Twitter as a business?

    “So far, it seems that this approach is only further alienating some media companies and some audiences on Twitter. However, research shows that almost half of the audience on Twitter goes there to get news. Musk no doubt knows this and may feel that news organizations will eventually need to come back to Twitter if they want to distribute their content to their audience.”

    Q: What alternatives do news organizations have when it comes to social media platforms?

    “News organizations must grapple with the fact that, given changes to Facebook’s algorithms, their content has less emphasis there. News organizations could perhaps look to TikTok as another place to distribute their content, but with that app currently under congressional scrutiny, that may not be an ideal option. Thus, Twitter still remains an important resource for news organizations that want to get their content into social streams.”

    Q: Is there any way these conflicts work in Elon Musk’s favor?

    “Musk gains a few things by this behavior. General trust in the news media has been on a decline for decades. These trust levels are particularly low among Republicans and independents. By taking on ‘big media,’ Musk is able to position his version of Twitter among those two demographics as a place that may be more open to an exchange of ideas. That may attract new users to Twitter in the future, but so far things haven’t worked out that way.”

  • The claim that U.S. temperatures are not trending upward is false

    The claim that U.S. temperatures are not trending upward is false

    [ad_1]

    Fact Check By:
    Newswise

    Truthfulness: False

    Claim:

    Zero US warming in 18 years, per US Climate Reference Network temp stations. That’s no US warming despite 30% of total manmade CO2. Emissions-driven warming is a hoax.

    Claim Publisher and Date: Steve Milloy on 2023-02-26

    A tweet shared by thousands by Steve Milloy, founder of Junk Science and former member of the EPA transition team under the Trump Administration, says, “Zero US warming in 18 years, per US Climate Reference Network temp stations. That’s no US warming despite 30% of total manmade CO2.” This claim is similar to ones in the past where skeptics of human-caused climate change cherry-pick data (using a fraction of the data to prop up claims that are false globally) to suit their ideology. It is simply false to claim that data from the Climate Reference Network show no warming over the last 18 years. There is a warming trend. Even if it was true, the US represents only 1.9 % of the Earth’s surface. It’s hard to extrapolate much about global temperature change from an 18-year period in 2% of the globe.

    According to data from the National Oceanic and Atmospheric Administration (NOAA), nine of the top 10 warmest years on record for the contiguous 48 states have occurred since 1998, and 2012 and 2016 were the two warmest years on record. Some parts of the United States have experienced more warming than others. According to NOAA, the North, the West, and Alaska have seen temperatures increase the most, while some parts of the Southeast have experienced little change. This warming trend is consistent with the long-term trend of global warming, primarily driven by human activities, particularly the burning of fossil fuels that release greenhouse gases into the atmosphere. 

    Chris Cappa, chair of the Department of Civil and Environmental Engineering, University of California, Davis has this to say…

    As usual, Steve Milloy is contributing to a disinformation campaign about the reality and seriousness of climate change through selective cherry picking of information. He conveniently ignores the undeniable global trend in surface temperatures to mention only the continental US, which is only 2% of the total Earth surface area. He misleads the public here by spinning a tale that is the equivalent of someone living in Chicago and saying they don’t believe that hurricanes are real because they’ve never seen one. Milloy peddles this same nonsense year after year and refuses to engage with the actual science.

  • We cannot predict earthquakes with accuracy, despite claim

    We cannot predict earthquakes with accuracy, despite claim

    [ad_1]

    Following the devastating earthquakes that struck Turkey and Syria in early February 2023, claims on social media went viral concerning how a Dutch scientist predicted the disaster days before the first quake that read 7.8 on the Richter scale. See here and here for examples. The claim stems from a tweet by Frank Hoogerbeets, a Dutch researcher from the ‘Solar System Geography Survey (SSGEOS).” On February 3rd, 2023, Hoogerbeets tweeted, “Sooner or later there will be a ~M 7.5 #earthquake in this region (South-Central Turkey, Jordan, Syria, Lebanon).” He included a map, showing a red circle on roughly the same area where the quake hit. In the past, Hoogerbeets has been described as a “quake mystic” who believes the movement of planets in our solar system can help us predict earthquakes. However, the USGS, one of the world’s most leading scientific organizations on earthquakes, unequivocally says that no scientists have ever predicted a major earthquake. “USGS scientists can only calculate the probability that a significant earthquake will occur (shown on our hazard mapping) in a specific area within a certain number of years.” Therefore, this claim that Hoogerbeets predicted the earthquake using scientific methods is false.

    While scientists have made significant advances in understanding earthquakes, there is no reliable method for accurately predicting earthquakes with a high degree of certainty. Scientists use various methods to monitor and analyze seismic activity, including seismometers, GPS sensors, and satellite data. They also study the geological characteristics of fault zones and other factors that can influence earthquake activity.

    While these methods can provide valuable insights into earthquake activity, they cannot accurately predict earthquakes. At best, they can provide early warning systems, allowing people to take precautions and minimize the impact of earthquakes. However, even these early warning systems are limited in their ability to provide timely and accurate predictions of earthquakes.

    Prof. Javed N Malik, an earthquake expert at the Indian Institute of Technology, Kanpur, India has this to say…

    The area where the recent Turkey / Syria earthquake occurred is known for its seismic volatility. The deformation caused due to tectonic activities in the Anatolian plate has been noted for some time now.

    A detailed study of any affected area over a period of time can result in informed speculation about the upcoming activities. These are established with extensive scientific data collection based on multiple aspects like planetary movement, GPS tracking, four shocks theory, animal behavior mapping, electronic reactions and many more.

    However, any of the above can simply result in an approximate and calculated prediction, and not an assurance of the same. In the past, we have witnessed these predictions to have been preventive, but also many a times no activity has occurred as denoted on the dates and numbers.

    Many research groups all over the world are working on methods to better the process, but to my knowledge we have yet to reach a stage where it can be predicted with a 100% certainty.

  • We cannot predict earthquakes with accuracy, despite claim

    We cannot predict earthquakes with accuracy, despite claim

    [ad_1]

    Following the devastating earthquakes that struck Turkey and Syria in early February 2023, claims on social media went viral concerning how a Dutch scientist predicted the disaster days before the first quake that read 7.8 on the Richter scale. See here and here for examples. The claim stems from a tweet by Frank Hoogerbeets, a Dutch researcher from the ‘Solar System Geography Survey (SSGEOS).” On February 3rd, 2023, Hoogerbeets tweeted, “Sooner or later there will be a ~M 7.5 #earthquake in this region (South-Central Turkey, Jordan, Syria, Lebanon).” He included a map, showing a red circle on roughly the same area where the quake hit. In the past, Hoogerbeets has been described as a “quake mystic” who believes the movement of planets in our solar system can help us predict earthquakes.

  • Fact-checking the reporting of the explosion in East Palestine, Ohio

    Fact-checking the reporting of the explosion in East Palestine, Ohio

    [ad_1]

    Five days after a Norfolk Southern train carrying vinyl chloride derailed and exploded near the Ohio-Pennsylvania border, crews ignited a controlled burn of toxic chemicals to prevent a much more dangerous explosion. Local residents of East Palestine, Ohio are wondering whether returning to the area is really safe. In a report from television station WXBN in Youngstown, Ohio, it was disclosed that additional toxic chemicals have been discovered in the area. A comment made by Sil Caggiano, a hazardous materials specialist, was included in the WXBN report. Caggiano said that “We basically nuked a town with chemicals so we could get a railroad open.”  The quote has been shared by thousands on social media. Christopher M. Reddy, a Senior Scientist at the Department of Marine Chemistry and Geochemistry at Woods Hole Oceanographic Institution cautions that this statement may be hyperbole.

    “Do not let the ‘doom and gloom’ overwhelm you,” says Reddy. In response to the Caggiano’s “nuked a town” statement, Reddy says it is “totally irresponsible. A very different situation when perceived by the public.”

    Reddy’s comment on the reporting of the incident:

    I would caution that the outcomes and scenarios available on Wikipedia are often overgeneralized and lack nuance.  I don’t wish to downplay this accident at all. Very different situation. It is very hard to predict the short and long-term impacts of any chemical release with great certainty, but I don’t foresee with the knowledge in hand, significant long-term impacts. All of these chemicals are relatively short-lived and unlikely to persist for many months, and they have a low affinity to bioaccumulate in human and animal tissue.”

    Reddy recommends the following for local residents:

    1. Remain cautious
    2. Do not let the “doom and gloom” overwhelm you.
    3. Ask for the sampling plans. Have samples been collected? When? Where? What is the detection limit?
    4. Ask for laboratory results for the chemicals that were released and their breakdown products.  (Key point—the actual chemicals.) I cannot speak for the level of analyses being performed, but these are complex measurements. Certainly not the equivalent of pH paper.
    5. Seek information from reputable sources.

    Mark Jones, a retired industrial chemist has this to say…

    The chemicals, now four, are all dangerous in multiple ways. They can be acutely toxic, chronically toxic and they are all flammable. The controlled burn takes flammable materials to more benign materials. In the case of vinyl chloride, a product of combustion is hydrochloric acid, itself dangerous but not flammable.

    The comment about a “more dangerous explosion” is a bit misleading. There is a risk to those attempting to clean up the site if there is a reservoir of flammable material. Reducing that risk is one of the reasons to do a controlled burn. There are many ways to do a controlled burn and I don’t know exactly what was done here.

    Two of the materials, vinyl chloride and isobutylene, are quite volatile. Isobutylene handles approximately like butane, the stuff in a lighter. It is a liquid under just a little bit of pressure. Release the pressure and it becomes a gas. Vinyl chloride is similar. When released, both become a gas. They should not persist on the site. They should be swept away in the air.

    The other two materials, ethylene glycol monobutyl ether and ethylhexyl acrylate, are higher boiling liquids. Both are flammable. The controlled burn of these materials should destroy them and make only carbon dioxide and water.
