Social Work is Advancing Addiction Science Research
Tens of thousands of Americans die from drug use and addiction every year, with overdoses killing over 63,000 people in America in 2016, according to the National Institute on Drug Abuse. Add in deaths linked to alcohol overuse and tobacco, and the number climbs above half a million Americans. The collective work of several researchers at the USC Suzanne Dworak-Peck School of Social Work, in collaboration with other USC faculty and outside organizations, is advancing knowledge of substance use disorders. Social work has become a hub where researchers and practitioners drive understanding and improve treatment for this disease that impacts millions of families each year. “Either as a cause or consequence, addiction relates to every problem we deal with in social work,” said John Clapp, professor and associate dean for research and faculty development at the USC Suzanne Dworak-Peck School of Social Work. Addiction’s complexity The social work field is uniquely poised to help effect change because of its holistic approach to individual well-being and the public good. According to Clapp, substance use disorder problems are inherently ecological, impacting and being impacted by individuals, families, peers, neighborhoods, communities and public policy in complex and dynamic ways. Untangling those causes and effects and interdependencies is one part of the solution. The other part is understanding that simple solutions may stay out of reach. “We will not find a one-size-fits-all answer,” said Clapp. Looking at addiction as a genetic, psychological or sociological issue only shows one piece of the overall cause. A comprehensive approach is essential, he said, especially when statistics from the National Institute on Alcohol Abuse and Alcoholism (NIAAA) show alcohol use disorders alone as the third leading cause of preventable death in the world. A hub for addiction science The need for a transdisciplinary response to this worldwide crisis was behind the 2018 creation of the USC Institute on Addiction Science (IAS), a joint venture between social work and the Keck School of Medicine of USC, with membership from 10 different schools, colleges and hospitals. Its vision is to strengthen the discipline of addiction science and improve the lives of those touched by the disease. Clapp is co-director of the institute and one of its founding architects. IAS is quickly becoming the foremost place for a broad effort focused on addiction that brings together researchers from the fields of public health, social work, law, public policy, mathematicians, computer engineers and others in recognition of the promise of new approaches to longstanding problems. The USC Suzanne Dworak-Peck School of Social Work has eight faculty making substantial contributions to the prevention of addiction-related disorders as members of the IAS: Professor Avalardo Valdez, associate professors Julie Cederbaum and Alice Cepeda, and assistant professors Jordan Davis, Shannon Dunn, Jungeun Olivia Lee, Danielle Madden, and Hans Oh. “Social work brings one of the broadest perspectives on the underpinnings and solutions to the addiction crisis,” said Adam Leventhal, director of IAS and professor of preventive medicine and psychology at Keck. “By approaching addiction as a health condition and a social justice issue, social work brings to the table the opportunity for high-impact, multi-modal intervention and social policy approaches, which are needed to address the addiction epidemic.” A holistic approach Social work faculty are raising the bar in addiction science research, developing new and novel approaches to improving outcomes for those affected by addiction. In a study recently published in Addiction, a multidisciplinary team lead by Davis and Clapp found gender differences in the risk factors for relapse following treatment for opioid use disorder. The study was the first in this field to use machine learning techniques to process large data sets and identify risk factors for relapse, said Davis, who also serves as associate director of the USC Center for Artificial Intelligence in Society (CAIS). The findings may result in more personalized treatment for opioid use disorder with lasting results. This dovetails with additional research Davis is conducting with computer science engineers at CAIS to collect and input neighborhood and census data into their models in an effort to better understand how these macro variables affect relapse. “We are finding that data points such as crime statistics, population density and concentrated poverty tend to be some of the most important predictors of relapse, over and above individual-level predictors such as impulsivity, motivation or gender,” Davis said. These findings echo Clapp’s description of addiction as ecological and point to the need for holistic solutions. “These machine learning techniques are helping us gain an apparent picture of what the most important factors are surrounding someone’s recovery,” Davis said. “Environment matters greatly.” Davis is also collaborating closely with Eric Pedersen, associate professor at Keck School of Medicine at USC, on several research efforts examining substance use among veterans. Most recently, they have assembled a survey group of approximately 1,200 veterans whom they survey quarterly about their well-being. A recently conducted survey of the group found that veterans with PTSD prior to the COVID-19 pandemic were now managing their symptoms with more frequent alcohol and cannabis use. Another joint research endeavor between the two is examining the use of mindfulness smart phone apps to help reduce substance use in Operation Enduring Freedom/Operation Iraqi Freedom veterans with PTSD and alcohol use disorder. Where well-being and inequalities intersect Jungeun Olivia Lee also seeks to decode the network of relationships between socioeconomic status, adverse childhood experiences and drug use. Her experience as a social work practitioner working directly with clients drives her motivation to demonstrate to policymakers what she sees as a linkage between unemployment, economic stress and substance use disorders. She is lead author on a paper published in Nicotine & Tobacco Research that found unemployment may advance nicotine addiction among young adults, rather than the idea that nicotine addiction may lead to unemployment. Lee’s research interests lie at the intersection of substance use and co-occurring mental health, social inequalities (such as poverty and low socioeconomic status), and adverse childhood experiences. She is interested in combining these three areas of inquiry to explore their influence on addictive behavior that can persist over generations of at-risk families, such as adolescent mothers and their children. Her memories of working directly with clients struggling with the impact of addiction remain clear in her mind. When Lee hears policymakers and others suggest that individual willpower will solve substance use disorder problems, she has a straightforward response: “People are not born with addiction.” In her view, many factors contribute to the triggered distress, including socioeconomic status and adverse childhood experiences. Lee is exploring an idea with other IAS researchers to investigate the relationship between financial strain and employment uncertainty and addiction. “Individual circumstances, such as losing a job, certainly influence substance use, but policy-level decisions, such as the generosity of unemployment insurance, can mitigate the impact,” she said. Transdisciplinary collaboration with social scientists, psychologists and medical researchers at IAS and across the USC campus enriches and amplifies her work. “We are breaking down discipline-specific silos and bringing new and valuable perspectives to this work,” she said. “The synergy is both useful and inspiring.” Looking ahead Researchers also hope to spark interest in the field among the next generation. A new minor for undergraduate students in addiction science was introduced at USC in Fall 2020. The minor is an interdisciplinary collaboration of the Keck School of Medicine, the USC Suzanne Dworak-Peck School of Social Work, the USC School of Pharmacy and the USC Dornsife College of Letters, Arts, and Sciences. It is designed to provide students with a transdisciplinary approach to understanding and treatment of the broad spectrum of addiction-related problems. The goal of addiction science research and education is to improve the long-term effect of addiction treatment and save lives. As society’s understanding of the cause of addiction grows, researchers like those in the school of social work and the IAS strive to bridge the gap between science, practice and policy to positively impact outcomes for those affected by addiction.
The Food and Drug Administration and the Centers for Disease Control and Prevention recently lifted the pause on the Johnson & Johnson COVID-19 vaccine. The agencies had shelved the vaccine after it was linked to cases of an extremely rare blood clotting disorder. Public health officials are now concerned that as news gets out about the potential side effects of the Johnson & Johnson vaccine, some members of the Black and Hispanic communities may opt out of what could be a life-saving act. “To the Black and Hispanic communities, there has been a long history of untrustworthy behavior by health care systems, and the current issue with Johnson & Johnson may have worsened some hesitancy,” said Dr. Justin X. Moore, an epidemiologist in the Department of Population Health Sciences at the Medical College of Georgia. “To overcome this barrier, companies must continue being open about side effects of the vaccine, and health care workers must be empathetic and listen to their patients’ concerns.” Vaccine safety and the importance of everyone being vaccinated is crucial as America looks to get to the light at the end of this pandemic. If you are a journalist covering COVID-19 and the issues surrounding vaccine hesitancy, then let our experts help.

Combating Vaccine Hesitancy Through Messaging
As vaccine hesitancy becomes a threat to Americans' decision to get the COVID vaccine, persuasive messaging is at the forefront of changing people's minds. Allyson Levin, PhD, a visiting assistant professor of communication, believes social media messaging plays a key role—and that post-vaccination selfies can actually help convince people to get the vaccine. "When we don't know what to do, we look to others to guide our behavior," stated Dr. Levin. "It is really important when we see people who share online that they were vaccinated—who are close to us, our friends or family and people we look up to like influencers and celebrities." Further, online communities create a world where it appears that people are getting vaccinated actively. "If we look around and see an environment where people are getting vaccinated, we will want to get vaccinated as well. That will encourage vaccination. At least if we trust those people around us," said Dr. Levin. Dr. Levin also contends that the social media platform TikTok can be extremely useful when information is "scientifically valid, evidence-based and coming from people who understand science like medical professionals." "A unique opportunity we have with TikTok is that users are receiving health information when they aren't looking for it," said Dr. Levin. In addition, she notes the incredible impact company advertisements endorsing COVID vaccinations have had on their wider acceptance. "At the end of the day, it is wonderful that brands are amplifying these messages, like Budweiser donating their airtime during the Super Bowl. There is an element of public relations, too: The brands look good for promoting these messages. But the more people that see these messages, the better." However, Dr. Levin pointed out that, while messaging is extremely important, vaccine availability is crucial. "Access is equally important. Unless people can actually have access to the vaccinations, the message is just one part of it," stated Dr. Levin.
Kelley expert available to discuss Bernard Madoff's legacy, long-term effect of his scheme
Bernard “Bernie” Madoff, convicted architect of an infamous and epic securities Ponzi scheme with thousands of investors, died behind bars on April 14 at the age of 82. Noah Stoffman, an associate professor of finance and Weimer Faculty Fellow at the Indiana Kelley School of Business, has researched the effect of such fraud beyond the direct investments that were lost by victims. His 2018 paper, “Trust Busting: The Effect of Fraud on Investor Behavior,” co-authored with professors at Cornell University and the University of Texas-Dallas, showed that the collapse of the Madoff Ponzi scheme had an effect not only on his many direct victims, but also on the general level of trust in financial services. “People who live in the same areas as victims of the fraud withdrew assets from investment advisers and increased their deposits in banks. Financial advisers in these areas were also more likely to close. Our analysis shows that advisers who provided services that can build trust—such as financial planning advice—saw lower levels of withdrawals. Our evidence suggests that this decline in trust shock was transmitted through social networks,” Stoffman said. Stoffman’s research focuses on the investment decisions of professional money managers and individual investors, and on the effect of technological innovation on asset prices. Much of his work highlights the importance of social interaction in the spread of information in financial markets. Stoffman teaches courses on analysis of financial data to undergraduates, MBAs, and doctoral students at the Kelley School. He can be reached at 812-955-1758 (m) or nstoffma@indiana.edu.
Learning online honestly. Is cheating becoming part of the ‘new normal’ in education?
The emergence of COVID-19 has seen almost every segment of society and traditional institution in America have to pivot drastically to sustain and carry on, especially the educational system. And as students across America had to log on and learn remotely in the last year, occurrences of cheating are trending upwards. It’s a phenomenon that is getting a lot of attention and University of Mary Washington Psychology Professor David Rettinger, an expert on academic integrity, is getting a lot of calls from media about it. Roughly a year after college campuses were evacuated due to the COVID-19 pandemic, academic integrity remains an issue for students and professors alike. With professors struggling to curb rampant cheating during online exams and students wrestling with the often confusing and stressful realities of online learning, the college classroom has never been more tense… Teen Vogue has spoken with academics and students to learn more about what kind of cheating is happening during remote learning, and what they think should be done about it. University battles with help sites have peaked during the COVID-19 crisis, but the root of the problem has been years in the making. “I call it a game of whack-a-mole,” says David Rettinger, president emeritus of the International Center for Academic Integrity (ICAI) and director of academic integrity at the University of Mary Washington. New sites are constantly rising in popularity, he explains, making it harder for professors to prevent students from seeking answers online, especially now. March 04 – Teen Vogue And how even the most respected of institutions like West Point are handling these cases have also seen Rettinger’s expert perspective sought out to explain. “Expulsion flies in the face of everything we understand about the psychology of ethical and moral behavior,” Rettinger said. That’s partly because the section of the brain that makes you feel “icky” when you do something wrong isn’t fully developed until around age 23 to 26 — after college is over. Rettinger said rehabilitation seems in line with West Point’s mission — to instill the values of duty, honor and country. “That doesn't necessarily mean weeding people out who are imperfect, because we're all imperfect,” Rettinger said. “That means taking the best cadets we can and turning them into the best officers they can be, which means teaching them. And if there's no opportunity for redemption, what are we really teaching?” March 08 – NPR The concept of cheating and how schools are handling it is an emerging issue in America.

Why online recommendations make it easier to hit “buy”
When it is time to buy something online, perhaps a coffee maker, you might head to Amazon and browse items for sale. One particular model might spark interest. The product page may contain recommendations for other goods: complementary products such as coffee filters; or recommendations for different, competitor coffee maker brands offering unique features and prices. E-commerce websites commonly use product recommendations — called co-purchase and co-view recommendations — to keep users locked into the sales funnel and increase customer retention. But what impact do these types of recommendations actually have on consumers? How do they influence one’s willingness to pay for the original product searched? In fact, the level of influence depends on how close a consumer is to making that purchase, says Jesse Bockstedt, associate professor of information systems & operations management at Emory’s Goizueta Business School. In addition, what type of recommendation the consumer sees plays a role in purchasing as well. To shed empirical light on this, Bockstedt teamed with Mingyue Zhang from the Shanghai International Studies University. “We were curious. We knew that recommendation systems are integral to how consumers discover products online – a good 35 percent of Amazon sales can be attributed to recommendations, for instance,” Bockstedt says. “But we knew a lot less about how recommendations change consumer behavior in relation to a focal product.” Specifically, the researchers were interested in looking at the effect of complementary versus substitutable products, and what impact the price of these types of products had on consumer behavior. They also wanted to know whether these effects were more or less amplified depending on whether consumers were at the exploratory phase in the buying process or ready to go ahead and make the purchase. To unpack the dynamics at play, Bockstedt and Zhang ran two experiments that simulated the online purchasing experience. The researchers had volunteers go through the process of evaluating different products and then report back on how much they were willing to pay for each. “We asked volunteers to look at a product page for a computer mouse, and we randomly assigned different recommendations to that page – some that were for other mice, and others that were for goods and products that would complement the original mouse. Going through the experiment, we also manipulated the price that volunteers saw on different pages, both for the recommended substitute and complementary products,” he says. “Finally, we looked at the effect of timing and the sales funnel. In one case we had volunteers look for a highly specific mouse and recommended a particular product page to them. To simulate the more exploratory phase, we gave them many pages and asked them to click on the one they found most interesting.” In total, Bockstedt and Zhang put 200+ volunteers through the replica virtual purchasing experience and recorded their willingness to pay the advertised price for the focal product on scale of 0 to 100, depending on what they had seen and the point in the sales funnel they had seen the recommendations.

Telecommuting Expert Predicts Permanent Changes to Work After the Pandemic
With the sudden shift to remote work brought about by the COVID-19 pandemic, many corporations have had to quickly assemble a patchwork of policies, procedures, and technologies. Timothy Golden, a professor in the Lally School of Management at Rensselaer Polytechnic Institute, foresees that many companies will adopt remote work on a permanent basis, and need to devote considerable attention and focus to systematically assessing the lessons they have learned. Golden is a leading expert in the field of telecommuting, telework, and the relationship between technology and managerial behavior. With more than 20 years of experience studying the impact of remote work on corporations and individuals, Golden’s insights about the future are rooted in a deep understanding of the history of remote work. In the wake of the pandemic, Golden envisions companies adding a Chief Remote Work Officer, who is responsible for maintaining the effectiveness of the company’s remote work program, to their C-Suite. This person will likely be a boundary spanner who garners resources and support from across silos in the company to ensure remote work remains effective in its long-term implementation. With the continuing importance of remote work, the Chief Remote Work Officer will need a seat at the executive table to ensure it receives the attention it needs. With remote work becoming even more firmly engrained in corporate cultures, Golden expects changes in the ways employees interact. With large numbers of employees continuing to work remotely, employees will expect support for this work mode in many forms — from promotion opportunities and performance metrics, to mentoring and technology support. Another implication of remote work going forward is that the demand for real estate will change, and companies will see real estate as platforms for collaborative work, rather than simply for work. With a significant permanent portion of the workforce likely to remain as remote workers, companies will be able to scale back their real estate yet also reallocate existing spaces to ones that are used for more collaborative interactions, rather than simply offices for individualized working. Golden is available to speak about these and other aspects of the future of remote work, as well as specific lessons he has learned through decades of studying this topic.
Online ratings systems shouldn’t just be a numbers game
When you’re browsing the internet for something to buy, watch, listen, or rent, chances are that you will scan online recommendations before you make your purchase. It makes sense. With an overabundance of options in front of you, it can be difficult to know exactly which movie or garment or holiday gift is the best fit. Personalized recommendation systems help users navigate the often-confusing labyrinth of online content. They take a lot of the legwork out of decision-making. And they are an increasingly commonplace function of our online behavior. All of which is in your best interest as a consumer, right? Yes and no, says Jesse Bockstedt, associate professor of information systems and operations management at Emory’s Goizueta Business School. Bockstedt has produced a body of research in recent years that reveals a number of issues with recommendation systems that should be on the radar of organizations and users alike. While user ratings, often shown as stars on a five- or ten-point scale, can help you decide whether or not to go ahead and make a selection, online recommendations can also create a bias towards a product or experience that might have little or nothing to do with your actual preferences, Bockstedt says. Simply put, you’re more likely to watch, listen to, or buy something because it’s been recommended. And, when it comes to recommending the thing you’ve just watched, listened to, or bought yourself, your own rating might also be heavily influenced by the way it was recommended to you in the first place. “Our research has shown that when a consumer is presented with a product recommendation that has a predicted preference rating—for example, we think you’ll like this movie or it has four and a half out of five stars—this information creates a bias in their preferences,” Bockstedt says. “The user will report liking the item more after they consume it if the system’s initial recommendation was high, and they say they like it less post-consumption, if the system’s recommendation was low. This holds even if the system recommendations are completely made up and random. So the information presented to the user in the recommendation creates a bias in how they perceive the item even after they’ve actually consumed or used it.” This in turn creates a feedback loop which can reflect authentic preference, but this preference is very likely to be contaminated by bias. And that’s a problem, Bockstedt says. “Once you have error baked into your recommendation system via this biased feedback loop, it’s going to reproduce and reproduce so that as an organization you’re pushing your customers towards certain types of products or content and not others—albeit unintentionally,” Bockstedt explains. “And for users or consumers, it’s also problematic in the sense that you’re taking the recommendations at face value, trusting them to be accurate while in fact they may not be. So there’s a trust issue right there.” Online recommendation systems can also potentially open the door to less than scrupulous behaviors, Bockstedt adds. Because ratings can anchor user preferences and choices to one product over another, who’s to say organizations might not actually leverage the effect to promote more expensive options to their users? In other words, systems have the potential to be manipulated such that customers pay more—and pay more for something that they may not in fact have chosen in the first place. Addressing recommendation system-induced bias is imperative, Bockstedt says, because these systems are essentially here to stay. So how do you go about attenuating the effect? His latest paper sheds new and critical light on this. Together with Gediminas Adomavicius and Shawn P. Curley of the University of Minnesota and Indiana University’s Jingjing Zhang, Bockstedt ran a series of lab experiments to determine whether user bias could be eliminated or mitigated by showing users different types of recommendations or rating systems. Specifically they wanted to see if different formats or interface displays could diminish the bias effect on users. And what they found is highly significant.

Why customers hold the key to a company’s true valuation
When determining a fair valuation for a company—especially in anticipation of an initial public offering (IPO)—investors often rely heavily on “top down” approaches focusing primarily on traditional financial measures to do so. But what if this approach doesn’t paint the full picture? Daniel McCarthy, assistant professor of marketing at Emory’s Goizueta Business School, is building the case that augmenting traditional data sources with customer behavior data gives investors a more accurate company valuation. For the past several years, McCarthy and Peter Fader, professor of marketing at the Wharton School of the University of Pennsylvania, have worked to refine a customer-driven investment methodology they created. “Customer-based corporate valuation (CBCV) simply brings more focus to how individual customer behavior drives the top line,” they explained in “How to Value a Company by Analyzing Its Customers,” an article published in the Harvard Business Review (HBR) earlier this year. “This approach is driving a meaningful shift away from the common but dangerous mindset of ‘growth at all costs,’ towards revenue durability and unit economics—and bringing a much higher degree of precision, accountability, and diagnostic value to the new loyalty economy.” Fader, McCarthy’s PhD advisor while he was at Wharton, had done some of the seminal work on forecasting customer shopping/purchasing behaviors. This helped build baseline expertise for how one could go about the customer-level modeling. McCarthy recognized that this behavioral modeling could be put to good use in a financial setting, if done the right way. “There was this untapped source of intellectual property that’s been accumulating within marketing over the last 30 years,” McCarthy said. While other academics have done some conceptual work in the area, none, McCarthy noted, had done so in a way that was consistent with how financial professionals go about performing corporate valuation. McCarthy and Fader merged these well-validated customer-level models with standard corporate valuation methods, then put their resulting valuation tool head-to-head with alternative approaches. They found that their CBCV model subsequently outperformed. A full article on this subject is attached, within it, you will find key CBCV highlights such as: Using unit economics to more accurately predict revenue forecasts Gaining access to the right data The CBCV model is also good for managers and for customers Working to have publicly traded companies adopt CBCV McCarthy’s work on the CBCV methodology has earned him a number of awards, including the MSI Alden G. Clayton, American Statistical Association, INFORMS, and the Shankar-Spiegel dissertation awards.

Alternative Data Can Offer Insight into GameStop Action on Wall Street
Thomas Shohfi, an assistant professor in the Lally School of Management at Rensselaer, says that looking at alternative data can offer important insights into the turbocharged trading of GameStop. “Volatility in options on GameStop, Nokia, and AMC is exploding,” says Shohfi. “Short sellers are taking massive losses, covering their positions and pushing the stocks even higher. WallStreetBetters keep looking for soft spots in the hedge fund short portfolios to ‘blow up’ their value again and again. It’s a mob-fund mentality.” Working with a former student, Shohfi has analyzed trends from the WallStreetBets subreddit and other social media platforms. He can provide an astute understanding as to how investors have reached this moment, why this has happened, and what the impact that this event will have in the future. “Practitioners, investors, and analysts are always looking for an advantage,” according to Shohfi. “The biggest advantage that we see today is through alternative data. It’s just a rich environment to observe human behavior, incentives, and gender and disclosure effects that affect capital markets like we have seen with GameStop.”
