How to get storm-ready for active phase of Atlantic hurricane season

Despite a relatively quiet summer for hurricanes, experts warn that late August and early September is traditionally the most active time for storms in the Atlantic — and forecasters are still predicting an above-0 season. Budget for higher evacuation costs Costs for gasoline, meals and lodging are all up significantly this year, says Tulane University business professor Peter Ricchiuti who advises residents in vulnerable areas to budget for increases if they need to evacuate due to a major hurricane. He can speak about how airfares are up about 25%, hotels and motels have on average raised their room rates by a third and gasoline prices are about 40% higher than they were last year at this time. In Louisiana, the average cost of gasoline has risen from $2.75 to $3.85 in the last year, says Ricchiuti, professor of senior practice at the A. B. Freeman School of Business at Tulane University.  How to pack an emergency bag Tulane emergency response expert Mike Wallace can speak about how to be storm-ready for August and September. Here is his video guide for how to prepare an emergency ‘go bag’ now. Wallace is director of the Emergency & Security Studies Program at the Tulane University School of Professional Advancement. To speak with either Ricchiuti or Wallace, please contact Tulane University media relations at or Roger Dunaway at

Expert available to comment on Senate vote on U.S. climate and tax bill

Tulane University climate change policy and politics expert Joshua Basseches is available to discuss the historic vote on the Inflation Reduction Act and how it will impact efforts to combat climate change. Basseches is the David and Jane Flowerree Professor in Environmental Studies and Public Policy at Tulane University School of Liberal Arts. “The United States Senate has passed its first significant climate bill ever,” Basseches said. “While many U.S. states have been slowly chipping away at the problem of climate change for decades through regulatory policy, nothing on this scale (in terms of dollars) has ever been achieved in U.S. history. All the credible modeling suggests the passage of this bill will move us significantly toward our greenhouse gas reduction goals, as put forward by the Biden Administration.” “Modeling, of course, requires assumptions and only time will tell whether those assumptions will be met, but no matter what happens, this is a huge accomplishment politically. Getting to this point was difficult. Savvy advocates, frustrated by decades of inaction in Washington, D.C., decided to try something brand new: a demand-side policy strategy relying on big dollars (‘carrots’ rather than ‘sticks’) to accelerate the clean energy economy with only 50 Senate votes – all that is required for a budget reconciliation bill. This strategy appears to have worked, though Senators Joe Manchin and Kyrsten Sinema kept us in suspense until the last possible minute, on the eve of the August recess. States will continue to play the most significant role when it comes to policy ‘sticks,’ as well as ensuring all these federal dollars are spent as intended. There could not be a more exciting time to be researching the political economy of climate change mitigation in the U.S.” For interviews, contact Roger Dunaway at or 504-452-2906.

Expert Insight: President Biden’s COVID-19 ‘Rebound Positive’

UConn Health’s Dr. David Banach explains how a fully vaccinated and boosted person could test positive, negative, and positive again for COVID-19 within a 10-day span If anything, I would say this situation actually reinforces the importance of vaccination. — Dr. David Banach President Biden is back in isolation, testing positive again for COVID-19 despite testing negative a week after his initial positive test July 21. It may be a puzzling sequence, but there is an explanation. “It’s unlikely this is anything other than the original infection resurfacing,” says Dr. David Banach, infectious diseases physician and hospital epidemiologist at UConn Health. Biden’s physician says the president had been taking the antiviral drug Paxlovid, which is a standard treatment for those with COVID-19 who are considered “high-risk,” including older patients. Biden is 79. “It’s not unheard of for people to take Paxlovid, clinically improve, be antigen-negative, then ‘rebound’ a few days later as antigen-positive,” Banach says. Antigens are substances that cause an immune response. Antigen tests are commonly used in at-home testing and can yield results in 15 minutes by detecting antigens specific to COVID-19. Antigen tests differ from PCR (polymerase chain reaction) tests, which look for genetic material that indicates a COVID-19 infection. Due to the nature of his position, the president tests routinely. PCR testing generally is not recommended within 90 days of infection because if frequently remains positive positive for a prolonged period of time, even after patients recover and are no longer contagious, so Biden was given antigen testing instead. All signs point to the Paxlovid suppressing the antigens to undetectable levels, resulting in temporary negative results, followed by the “rebound.” As of Tuesday Biden’s only symptoms were a “loose cough,” according to a memo from his physician, Dr. Kevin O’Connor, who reported, “He remains fever-free and in good spirits.” The White House says the president is fully vaccinated and up-to-date on all his recommended boosters. “While this is another example of someone getting infected despite being is fully vaccinated and boosted, it’s important to understand the vaccines protected the president from serious illness from infection,” Banach says. “If anything, I would say this situation actually reinforces the importance of vaccination, especially for older people, those who are immunocompromised, or those with other health problems that could make them more vulnerable to serious illness.” Looking to know more about this topic - then let us help with your stories and coverage. Dr. David Banach is an expert on infectious diseases and epidemiology and is a leading expert on COVID-19 in America. To book an interview with Dr. Banach, click on his icon today.

Aston University pharmacy student wins Christopher J Hewitt Prize for exceptional student citizenship

The Christopher J Hewitt Prize for exceptional student citizenship in the College of Life and Health Sciences at Aston University has been awarded to Hanan Tahir a fourth year MPharm student, in recognition of his support in helping colleagues to develop and achieve their goals through mentoring and for his positive and supportive outlook, felt by all those around him. The prize is named after and in tribute of Professor Christopher J Hewitt FREng who was pro-vice chancellor and executive dean of the School of Life and Health Sciences and professor of biological engineering from November 2014 until July 2019. Chris sadly passed away on 25 July 2019 at the age of 50; an eminent scientist and truly devoted family man. To commemorate Chris’s life and to celebrate the values that he held dear, the Christopher J Hewitt Prize was established in 2021 to recognise exemplary citizenship through support of other students, contribution to the Aston University community or achievement in the face of adversity. The judging panel, which consisted of four research fellows and Chris’s widow Sandra Hewitt, felt that Hanan had achieved a lot through his work with Aston University student societies, where he is president of the Aston Pharmacy Society. Hanan also set up a mentoring scheme for first and second year students to help ease them into University life after the Covid-19 pandemic. The judges noted the substantial amount of charity work undertaken by Hanan including hiking up Snowden to raise £9000 for Syrian Refugees. They were also impressed by the nominations outlining the sense of fun and joy Hanan has helped to foster amongst his student peers. On receiving his award, Hanan said: "It's within our human nature to care for and support each other. We've grown to be so successful because we have always chosen to look out for others rather than isolate and try to go it alone. And I have always believed that an integral key to happiness is community. “I am honoured to have received this award. I am even more honoured that my efforts have been noticed and recognised. Aston University has always put inclusivity and community in everything it does and I hope that we all continue to emanate the values of this University as we progress through our lives." Sandra Hewitt, Chris’s widow, added: “It was an honour to once again be able to be part of the judging panel for the Christopher J. Hewitt Memorial Prize. Again, this year the candidates all exhibited the qualities and values of the prize, however we felt Hanan was a worthy winner for all the reasons mentioned above. Chris worked hard but he liked to party harder so the fact that Hanan’s nominations also mentioned his sense of joy and fun was especially relevant." Professor Anthony Hilton, executive dean of the College of Life and Health Sciences, said: “I am delighted Hanan is this year’s recipient of the Christopher J Hewitt Prize. It makes me exceptionally proud to see members of the College demonstrating the culture and values we hold dear and being held in such high regard by their peers.” The panel also highlighted the exceptional achievements of Negin Gholampoor for her work as the Aston Medical School representative to the British Medical Association and for striving to improve the systems around her and effect change for the benefit of her peers. A special mention was made for Erika Pond for her commendable display of citizenship when providing CPR to a stranger in need.

Women in STEM Careers Face Bias

Women are excluded from promotions when firms look at potential, rather than proof, says Dr. Nishtha Langer, an associate professor in the Lally School of Management at Rensselaer Polytechnic Institute. Promotions are an accepted way for firms to attract and retain talent. In an ideal world, promotion for employees would be purely merit-oriented, and thus, performance – or potential for performance – would be a firm’s most important criteria for career advancement. But, according to Dr. Langer, we don’t live in this idyllic world – we live in a world where women are evaluated differently than men, and often endure biases in the work environment that men don’t face. Dr. Langer believes that several factors contribute to such deleterious workplace practices. Promotions rely less on absolute merit and more on relative merit. Thus, prejudiced ideas of potential capabilities, for instance, those relying on gender-role orientation – or the ability of a woman to do what may be perceived to be a masculine task – may prevent senior managers responsible for promotions from realizing the potential of their female colleagues. Women in STEM or technology often suffer from this bias. This prejudice may further bias how women are evaluated. Especially in those jobs where women are a minority, the in-group versus out-group biases would affect the visibility of women vis-à-vis men for promotions. Another factor that may inhibit women from being promoted on the basis of potential – or even indeed with proof – is what researchers term the compensatory stereotype. If men succeed, it is because of their abilities; if women succeed, it is because of factors other than their abilities. Unfortunately, the potential or abilities of women are misattributed to luck or team factors, inhibiting them from the starting line. Finally, promotions are a way for firms to ensure valuable talent does not leave. In that sense, managers may be less sensitive to women’s outside prospects and may thus ignore their potential and choose to not promote them. They do so at their peril and fail to take advantage of the multitude of abilities women bring to the table. Dr. Langer, an authority in the field of business and the societal value of IT and IT human capital, has long focused her research on women in technology careers. She is available to speak to this and other concerns about equality in the workplace.
