Holiday shopping season set to begin with questions about Black Friday, consumer behavior

Is Black Friday still a thing? Online sales have been outpacing brick-and-mortar sales for years, resulting in shorter lines and less of a frenzy at stores on the day after Thanksgiving. Many stores have also gone online with deals to compliment in-person shopping. University of Delaware experts can comment on this and other topics related to the holiday shopping season and gift-buying behavior. Andong Cheng: Can provide tips on what to prepare for during this unique holiday shopping season. Her research focuses on defining and identifying the picky consumer segment, and explores how pickiness impacts other judgments and decisions. She advises consumers to consider the phenomenon of double mental discounting, where shoppers experience a “mental accounting phenomenon” when offered promotional credit. Jackie Silverman: Research examines several facets of judgment and decision making and consumer psychology. According to Silverman, there are many potential benefits of online shopping for consumers, including some unconventional approaches to gift giving this season. Philip Gable: Can talk about the science behind the art of gift-giving that goes beyond the material exchange — emotional nuances that also can be applied to charitable work and philanthropy. He says that significance contributes to the happiness we experience in gift-giving. Matthew McGranaghan: Studies the economics of consumer attention and the indirect effects of marketing interventions. He explains that there is a difference in how businesses are innovating and utilizing online retail methods to connect with consumers this holiday season. Bintong Chen: Can discuss the systematic nature of supply chain issues. He recommends shoppers use major retailers like Amazon and Walmart, whose companies use their own shipping fleets to minimize disruptions. Caroline Swift: Examines supply chain transparency and the interactions between regulation and business performance.

MEDIA RELEASE: Avoid the Winter Wallop: CAA, Toronto Police Service and OPP team up with winter weather readiness tips.

Almost one month before the official start of winter and CAA South Central Ontario (CAA SCO), Toronto Police Service (TPS) and Ontario Provincial Police (OPP) are joining forces to keep drivers safe before winter weather blows in with full force. The three organizations are teaming up to help inform Ontario drivers that now is the time to install winter tires, check their car batteries, and stock their cars with emergency car kits that include essentials for the winter months. “Ontario winters can be unpredictable, and snowstorms can hit suddenly. It’s always best to prepare ahead of time in case driving conditions become hazardous,” says Nadia Matos, manager of external communications, CAA SCO. “There’s no time like the present to ensure your safety before getting on the road.” Driving behaviour is the most important factor in ensuring safe driving operations in winter weather. "Road safety is everyone’s responsibility,” says Sergeant Murray Campbell, Toronto Police Service. “With fewer daylight hours and reduced visibility, we are urging everyone to remain vigilant, be aware of other road users, drive according to the weather conditions, ensure vehicle lights are on, and plan ahead to allow for extra travel time.” The organizations continue to reinforce last year’s amendments to the Highway Traffic Act, including the illegal passing of snowplows working in echelon on Ontario highways. “Not only is passing these plows illegal, but it is also incredibly dangerous,” says Sergeant Ted Dongelmans, Ontario Provincial Police. “Offenders may face a fine ranging from $150 to $1,000 if found passing a snowplow while they are clearing the roads.” Before heading out on the road this winter, motorists can download and use the 511 app to check the weather and road conditions before they leave home. The 511 app can be found at 511on.ca or in the app store on their mobile devices. For a safer trip this Winter, CAA, TPS and OPP are sharing the following motorist tips: • Test your car battery. If necessary, replace it before it fails. CAA SCO will test Members’ batteries free of cost during a service call. • Pack a fully stocked emergency car kit. The kit should include a flashlight, extra batteries, warning devices (e.g., flares, reflective vests/strips), a first aid kit, blankets, jumper cables, non-perishable food and water, and a phone charger. Be sure to always keep an ice scraper, small shovel, and snow brush handy in your car. • Service your vehicle. Have your brakes checked, oil changed and top up your windshield washer fluid and any other fluids that are getting low. • Keep your gas tank at least half full at all times. Cold weather causes condensation in the system, which can lead to fuel-line freeze-up and prevent a car from starting. • Check your lighting system. Ensuring you have full lighting is very important in the winter months. Check your headlights and signal lights to ensure they work correctly.

The Anxiety of Election Season

After the results of the U.S. presidential election were announced, many Americans celebrated. But many voters instead found only stress and anxiety. After an election of rhetoric that foretold the end of democracy if the opposing candidate won, there seems to be a unique amount of post-election stress. How did election rhetoric affect this outcome, and can we expect future elections to cause this same stress? Political expert, Dr. Mark Caleb Smith, discussed the anxiety that many Americans felt even before the election and how it can be dealt with moving forward. Here are some key takeaways from his recent interview: This election cycle caused so many Americans to lose sleep that the term "electsomnia" was coined. Has the anxiety of election season always been present, or has the presence of social media paved a way for this problem? Constant access to information about the election is a probable reason for many voters' anxiety. How can Americans keep themselves informed without causing unnecessary damage to their mental health? This is not the first complicated or difficult election that the United States has faced. Now that this election season is over, how can Americans—both those who are satisfied and those who are frustrated by the results—move forward while recognizing that politics does not define them? If you are a journalist covering the election results and voters' responses, our experts are here to help with all of your questions and stories. Dr. Mark Caleb Smith is the Director of the Center for Political Studies at Cedarville University. Mark is available to speak with the media regarding election emotions and the election results.

Is America Not Ready for a Woman President?

Newsday interviewed Dr. Meena Bose for the article, “After Kamala Harris loses, is America just not ready for a woman to be president? Experts say it’s not that simple.” Dr. Bose said that while gender may have played a role in Harris’ defeat, it’s the “not the dominant explanation” for Trump’s victory. “I don’t think that 2024 is a referendum on whether a woman can be president,” she said. “That’s not the dominant message here. The dominant message really is the economy and immigration. And for multiple reasons, the Democratic agenda was less persuasive to voters than the Republican agenda.” Dr. Bose is a Hofstra University professor of political science, executive dean of the Public Policy and Public Service program, and executive director of the Kalikow Center for the Study of the American Presidency.

Dangers of the Metaverse and VR for U.S. Youth Revealed in New Study

The metaverse, a space where the lines between physical and digital realities blur, is rising among younger populations. As of March, 33% of teens own a virtual reality (VR) device and 13% use it weekly. With the metaverse offering richer emotional experiences, youth may be particularly vulnerable to significant harm in these immersive spaces, underscoring the need to explore potential risks. Unfortunately, research of online victimization in the metaverse is sorely lacking. A new study by Florida Atlantic University , in collaboration with the University of Wisconsin-Eau Claire, is one of the first to examine the experiences of harm in the metaverse among youth in the United States. Using a nationally-representative sample of 5,005 13 to 17 year olds in the U.S., researchers focused on their experiences with VR devices, including 12 specific types of harm experienced, protective strategies employed, and differences in experiences between boys and girls. Results of the study, published in the journal New Media & Society, found a significant percentage of youth reported experiencing various forms of harm in these spaces, including hate speech, bullying, harassment, sexual harassment, grooming behaviors (predators building trust with minors), and unwanted exposure to violent or sexual content. The study also revealed notable gender differences in experiences. Among the study findings: 32.6% of youth own a VR headset (41% of boys vs. 25.1% of girls) More than 44% received hate speech/slurs (8.9% many times); 37.6% experienced bullying; and 35% faced harassment Almost 19% experienced sexual harassment; 43.3% dealt with trolling; 31.6% were maliciously obstructed; and 29.5% experienced threats More than 18% were doxed (publicly revealing someone’s personal information without their consent); and 22.8% were catfished (creating a false identity online to deceive someone, typically for romantic purposes) Nearly 21% faced unwanted violent or sexual content; 18.1% experienced grooming or predatory behavior; and 30% were targeted for factors like weight, sexual preference, sexual orientation or political affiliation Boys and girls experienced similar patterns of mistreatment, but girls experienced sexual harassment and grooming/ predatory behavior more frequently than boys. Boys and girls were equally as likely to be targeted because of their voice, avatar, race, religion or disability. “Certain populations of youth are disproportionately susceptible to harm such grooming, especially those who suffer from emotional distress or mental health problems, low self-esteem, poor parental relationships and weak family cohesion,” said Sameer Hinduja, Ph.D., first author, a professor in the School of Criminology and Criminal Justice within FAU’s College of Social Work and Criminal Justice, co-director of the Cyberbullying Research Center, and a faculty associate at the Berkman Klein Center at Harvard University. “Due to the unique characteristics of metaverse environments, young people may need extra attention and support. The immersive nature of these spaces can amplify experiences and emotions, highlighting the importance of tailored resources to ensure their safety and well-being.” Findings also reveal that girls employed in-platform safety measures significantly more so than boys such as “Space Bubble,” “Personal Boundary” and “Safe Zone.” “We found that girls are more likely to select avatars designed to reduce the risk of harassment and to use in-platform tools to maintain a safe distance from others. Additionally, both boys and girls feel comfortable leaving metaverse rooms or channels like switching servers in response to potential or actual victimization, although overall, youth tend to use these safety features infrequently,” said Hinduja. Among the recommendations offered to youth by the researchers include: Using platform-provided safety features to restrict unwanted interactions and infringements upon their personal space. It is also essential that youth understand and take advantage of the safety features available within metaverse experiences, including blocking, muting, and reporting functionalities. Continued research and development in these areas to determine how to meet the needs of users in potential or actual victimization contexts Streamlining platform reporting mechanisms to ensure swift action is taken against perpetrators Age-gating mechanisms for metaverse environments where mature content and interactions proliferate Encouraging parents and guardians to take the time to familiarize themselves with available parental control features on VR devices and metaverse platforms to set boundaries, monitor activities, and restrict certain features as needed. An active mediation approach is ideal, where they engage in open and supportive dialogue with children about their metaverse experiences. The integration of updated, relevant, and accessible digital citizenship and media literacy modules into school curricula to provide youth with the necessary knowledge and skills to navigate VR and other emerging technologies safely and responsibly Consideration by content creators of the ethical implications of their metaverse creations, ensuring that they promote inclusivity, respect, and discourage any form of harassment. They should strive to make their virtual experiences accessible to users from diverse backgrounds, languages, cultures and abilities. “VR concerns of parents and guardians generally reflect and align with their historical anxieties about video games, excessive device use, its sedentary nature, cognitive development, and stranger danger,” said Hinduja. “There remains so much promise with these new technologies, but vigilance is required when it comes to the unique challenges they present as well as the unique vulnerabilities that certain youth users may have. As such, it’s ‘all hands on deck’ to build a safer and more inclusive metaverse as it continues to evolve.” If you're looking to know more - let us help. Sameer Hinduja, Ph.D., is a professor in the School of Criminology and Criminal Justice at Florida Atlantic University and co-director of the Cyberbullying Research Center. He is recognized internationally for his groundbreaking work on the subjects of cyberbullying and safe social media use, concerns that have paralleled the exponential growth in online communication by young people. He has written seven books, and his interdisciplinary research is widely published and has been cited more than 18,000 times. Simply click on Sameer's icon now to set up an interview today.

News Outlets Take Measures to Explain Election Reporting

Mark Lukasiewicz, dean of The Lawrence Herbert School of Communication, talked to the Associated Press about efforts by the news media to show transparency when reporting election results. “It’s absolutely important for an organization to be as transparent as they can be, especially because there’s been an effort to challenge the credibility of calls,” said Dean Lukasiewicz. At the same time, it’s hard to do in a way that makes sense to people who are not statisticians or systems operation experts, he said.

Researchers race to detect Alzheimer's sooner using $3.9M grant

Too often, people learn they have Alzheimer’s disease when it’s too late. The changes in the brain that lead to the disease manifesting with symptoms have already been occurring for decades. Researchers at the University of Delaware will attempt to detect the disease sooner through a new study that examines changes in the arteries and brain tissue in midlife adults in their 50s and 60s. The findings of this work, funded by a nearly $4 million grant from the National Institute on Aging (NIA), could identify the earliest mechanisms linking vascular aging to the loss of brain tissue integrity, leading to new targets for interventions aimed at preventing age-related cognitive impairment. “People who develop high blood pressure or stiffening of the aorta and carotid arteries in midlife are at a much higher risk for developing cognitive impairment or dementia in late life,” said Christopher Martens, the principal investigator of the study. Martens, an associate professor of kinesiology and applied physiology in UD's College of Health Sciences and director of the Delaware Center for Cognitive Aging (DECCAR), is working closely with Curtis Johnson, an associate professor of biomedical engineering in the College of Engineering and leader of the neuroimaging biomarker core within DECCAR, on research funded by a nearly $4 million grant from the National Institute on Aging (NIA), a division of the National Institutes of Health (NIH). “A lot happens as we age, so we’re aiming to pinpoint the timing and exact mechanisms that cause these changes in midlife adults,” Martens said. This latest grant extends DECCAR’s ongoing Delaware Longitudinal Study for Alzheimer’s Prevention (DeLSAP), which seeks to study how risk and protective factors for dementia are related and change over time. Those eligible for DeLSAP could also meet the criteria for participating in the new study. In his Neurovascular Aging Laboratory, Martens studies mechanisms leading to the stiffening of arteries, while Johnson is specifically interested in measuring the stiffness of the brain. “As a person ages, the brain gets softer and breaks down, and we’re looking to see whether changes in arterial stiffness and patterns of blood flow in the brain cause this decline,” Johnson said. Changes in blood flow to the brain come from controllable factors. Smoking, cardiovascular health, diet and exercise all impact blood flow positively and negatively. “A lot of aging research is done at the end of life,” Johnson said. “We want to look at midlife and try to predict what happens later in life so we can prevent it.” While the brain gets softer with age, arteries get stiffer. “We hypothesize that midlife increases in stiffness in blood vessels cause damaging pulsatile pressure to enter the brain,” Martens said. “We believe this is one of the reasons we start to develop cognitive issues at an older age because the brain is exposed to increased pressure; that pressure is likely inflicting damage on surrounding brain tissue.” In Johnson’s Mechanical Neuroimaging Lab, researchers will use high-resolution magnetic resonance elastography (MRE) to determine where brain damage occurs and what specific brain structures may be affected. “From an MRI perspective, most researchers look at AD and other neurodegenerative diseases like multiple sclerosis with an emphasis on detection in a hospital setting,” Johnson said. “Using highly specialized techniques we’ve developed, we focus on the earlier side and how these changes progress into disease from the neuroscience side, emphasizing prevention.” Together, they’ll seek to learn whether arterial stiffness causes the kind of cognitive impairment seen in AD or whether the decline is associated with a loss in the integrity of brain tissue. “If we can prove arterial stiffness is playing a causal role in cognitive aging, that would provide further support for focusing on blood vessel health as an intervention for delaying AD or other forms of dementia versus solely focusing on the brain,” Martens said.

The 47th President

Former President Donald Trump was re-elected as the 47th president of the United States. He will be only the second president to serve two nonconsecutive terms—the first being Grover Cleveland in the 1800s. Much of the country shifted right this election cycle, resulting in Trump earning the electoral vote and the popular vote. This is the first time the Republican candidate has the earned the popular vote since 2004, during George W. Bush's reelection campaign. Political expert, Dr. Mark Caleb Smith focused in on how the Christian vote may have affected this outcome.In a recent Christianity Today article, Dr. Mark Caleb Smith provides some insight into how Christians voted in the most recent election. Here are some key points from the recent article: President Joe Biden is a lifelong Catholic, but since he dropped out of the presidential race, many Catholics voted for Trump rather than Vice President Kamala Harris. How did the Catholic vote for Trump shift from the last election? Trump's victory seems to indicate the importance of economics for American voters. Did Trump's economic policies sway the votes of evangelicals, rather than his stances on social issues like abortion? Although Trump had the majority of the evangelical vote, there is still a minority that rejects Trump on account of his character and tone. Did these voters lean towards the Democratic candidate, Kamala Harris, or did their votes go to third-party candidates?
