Fox School of Business MIS professor examines how the introduction of dynamic security warnings could lead to safer online behavior, ultimately eliminating hackers.
PHILADELPHIA, Jan. 13, 2020—Surf the net or play with your phone for any decent amount of time, and it’s inevitable that you’ve seen this familiar message before.
“Important update available. Install now.”
Yet, how often have you actually dropped what you’re doing to install the update? If you’re like the average technology user, you probably just ignore the message or ask to be reminded at a later date. However, a researcher at Temple University’s Fox School of Business says that could be a mistake.
“Our brains are wired to tune things out over time,” says Anthony Vance, an associate professor of management information systems in the Fox School. “The thing is, software updates fix security vulnerabilities that hackers know about and can take advantage of. As soon as Apple or Microsoft publishes these security updates, the whole world knows what needs fixing. Hackers start writing attacks to take advantage of these holes.”
Past research has outlined how it’s important to be proactive when it comes to updating software, but that’s easier said than done. Old habits die hard, and a person cannot be expected to immediately start paying close attention to software updates.
Vance’s new research could offer a solution. Recently published in MIS Quarterly, “Tuning Out Security Warnings: A Longitudinal Examination of Habituation through fMRI, Eye Tracking, and Field Experiments” investigates how changing the design of security warnings might help stop users from ignoring them. The research was presented last year in Santa Clara, Calif., during the Fifteenth Symposium on Usable Privacy and Security.
As part of the research, Vance and his research colleagues altered the design of typical security warnings and then tracked user reactions to the new designs over the course of five days through fMRIs and eye-tracking. These were not your run-of-the-mill security warnings. One featured a yellow, triangle-shaped warning sign. Another had a jiggle animation with it. One even quickly zoomed in and out.
The new designs seemed to have a positive effect.
“Those treatments sustained attention across the whole week,” Vance says.
Vance and his colleagues further tested these new security warnings during a field experiment. More than 100 participants were recruited to evaluate apps on, unbeknownst to them, a fake Android store. Out of a list of ten apps, participants were asked to download and evaluate three of them over a three-week period.
The permission warnings and visual displays varied, depending on the app. For some apps, the warnings were in line with a typical generic security warning. Others were more elaborate, similar to what users saw during the first part of the experiment.
“The people who saw the variations in warning designs had more secure behavior over time,” Vance says. “These designs are more resistant to us just doing the natural thing where we tune them out. By the end of the three-week period, nearly 80% of the folks who saw the dynamic security messages were still adhering to safe behavior compared to just 55% of those who saw the static warnings.”
Does this mean that we can expect our next security warning to come in the form of a flashing, luminous red light? Not necessarily.
“In this research, we were careful to design warnings that do not annoy people, like a blinking warning. We wanted to show that we could reduce habituation without making people’s computing experience worse. We found that even our comparatively restrained designs made a big improvement and that this improvement held over time,” Vance says. “Together, these findings provide the most complete view yet of how people habituate to security warnings over time, and the significant impact this can have on the effectiveness of warnings, the last line of defense in cybersecurity.”

Companies are feeling the pressure to use telework opportunities to satisfy employees. But how does working from home affect our productivity, creativity and stress levels?
“Flexible work arrangements are popular, but can often lead to higher stress,” warns Ryan Vogel, assistant professor in the Fox School’s Department of Human Resources Management. Vogel conducted a survey of over 500 U.S.-based employees of a multinational software corporation. He asked each employee to respond to a short questionnaire four times a day for three weeks, seeking to understand how their creativity, engagement and stress varies throughout the day and in different working environments.
There were no differences in either the employees’ investment in their work and degree of creativity when working from home, at the office or in a combination of the two settings. However, Vogel says, “We found significantly higher levels of stress and lower levels of positive emotion when employees worked at home.”
Why would employees feel more stress when working at home? “There could be several factors,” says Vogel. “But our research suggested the strongest factor was the fact that people are more psychologically attached to home when they are at home.” For example, many employees who are teleworking may find themselves distracted from their work to-do lists by their personal tasks. Imagine trying to work next to a giant pile of laundry—for some, that is hard to ignore.
Unsurprisingly, the same was true for those who brought their work with them, mentally or physically, after leaving the office. Employees who emphasized time in the evening to recover from work and engage with their families reported lower stress levels than those who did not.
“With flexible working environments, it’s important that employees can create mental distance between home and work,” says Vogel. “With the increased flexibility in how and where we work, we need to be conscious of creating some form of mental separation between the personal and the professional, so that employees can focus on each one when it’s appropriate.”
Vogel also advocates for an occasional change of scenery. “When employees switched work locations from one day to the next between their home or the office, we saw significant boosts in their level of engagement and lower levels of stress,” he says.
This study supports the notion that working at home versus in the office does not impact an employee’s ability to be creative and engaged in their work, but it does suggest that employers and companies should exercise telework options mindfully.
“Flexibility to work remotely is an important benefit that fulfills employees’ need for autonomy,” says Vogel. “However, these findings bring a level of nuance to the conversation.”
Reducing Stress at Work
Whether employees have flexible hours or are “always on,” how can companies help reduce stress levels? Vogel suggests ways that leaders can encourage employees to put aside stress-inducing distractions, regardless of their work environment:
- Make lists at the end of a day to let go of stressors overnight.
- Model “protected time” so employees do not feel pressured during non-work hours.
- Start meetings by setting an intention to be fully present and encouraging mindfulness

Almost everyone who works has a boss. It’s no secret that the quality of this relationship can have a big impact on the lives of supervisors and employees alike. The best bosses provide mentorship, training and support for their direct reports, facilitating professional growth and success for their team. But is it possible for employees, through their actions on the job, to impact their bosses as well?
Soojung Han, a PhD candidate in the Fox Department of Human Resource Management, thought so. During her five years as the first woman engineer at a South Korean petrochemical company, she had an outstanding relationship with her boss, who gave her an unusual amount of autonomy, respect and trust.
“I knew it was out of the ordinary from talking with my friends about their jobs, and I also knew it was important,” says Han. Every time her supervisor acknowledged her work or granted her additional responsibilities, she wanted to do an even better job. The experience had such a profound impact on her that when Han decided to pursue her PhD, she chose to focus her research on just this style of empowering leadership. Her personal connection to the subject is perhaps one reason her scholarship had been so exceptional.
Han and her colleagues’ recent paper, “Examining why employee proactive personality influences empowering leadership: The roles of cognition- and affect-based trust,” explores this territory. The research was published in May in the prestigious Journal of Occupational and Organizational Psychology. A publication of that caliber is a rare achievement for someone who is still a student. This fall, Han assumed a faculty position at Cal State Los Angeles.
Employee proactivity is often the catalyst for supervisors to grant workers greater autonomy and more responsibility, which increases employee engagement, productivity and job performance. Given the importance of these self-starters in the workplace, the proactive personality type is of great interest to researchers. However, to date, most of the research has focused on employee-centered outcomes, such as the relationship between proactive personality and career success. But the complex ways that an employee’s proactive style may affect his or her supervisor has been largely overlooked by scholars. That’s why Han decided to turn her attention to how these proactive employees affect their bosses.
“The proactive personality type is defined as someone who makes changes in their environment, so we suspected that these employees might change their supervisors as well,” she says. She gathered more than 100 pairs of supervisors and employees and surveyed them to assess the qualities in question: proactive personality, empowering leadership and supervisor trust. Via questionnaires, employees rated their own proactive personality traits and their boss’s leadership style, while leaders scored their direct report’s level of trust in an employee.
Han’s research examines two types of trust typical of work relationships: Cognition-based trust, which is based on logic and facts regarding an employee’s work responsibilities, and affect-based trust, which boils downs to whether or not a supervisor personally likes his or her direct report.
To test their hypotheses, Han and her coauthors used statistical models, including hierarchical multiple regressions, to analyze the data. The team found that supervisors were more trusting of employees with proactive personalities and thus were more likely to empower them.
“It’s risky for leaders to let employees make decisions,” says Han. “What if they lack skills or, worse, what if they take advantage of less supervision and more autonomy?”
Her work shows that, in spite of the risks, the payoff can be significant for an organization. Empowering leadership pays tangible dividends. “Previous research has supported that empowering leadership is associated with a host of positive outcomes, including increased psychological empowerment, task performance and citizenship behaviors for both individuals and teams,” says Han. She recommends that companies work on building both cognitive-based trust, through formal skill-building training, and affect-based trust, by taking the time to plan and invest in social events and team building.
This specific research paper gives the edge to affect-based trust—likability. But Han cautions that the two types of trust are more interrelated than they may first appear. “Though it seems like affect-based trust shows a stronger effect, its impact on empowering leadership is less likely to occur when cognition-based trust is low,” says Han. “Therefore, both cognition- and affect- trust are important to induce leaders’ empowering behaviors.
Her research also speaks to the importance of improved screening of prospective employees. It pays to be able to identify new hires who will consistently demonstrate proactive behaviors at work, not just say they will during a job interview. Han believes tools like personality tests and questionnaires that assess proactive traits specifically would be helpful as companies seek to fill their ranks with these go-getters.
“As we can see, their proactive style benefits not only the employees themselves, but their supervisors, too,” says Han.

Big data is a buzzword everywhere in the business world, but there are a few specific sectors where this revolution is making an especially big impact: information systems, operations management and healthcare.
That’s why Subodha Kumar, the Paul R. Anderson Distinguished Professor of Marketing and Supply Chain Management at the Fox School, turned his attention to these areas. While big data experts across the board have breakthroughs in their individual fields, Kumar’s research focuses on the importance of sharing these advancements, as well as the data and systems that made them possible. Cross-pollination of ideas will be the key to future progress, according to Kumar.
The insights Kumar gleaned from his analysis of the existing academic research in these specific sectors informed his predictions and recommendations for how businesses might harness big data s in the future. “The whole idea is that there have been a lot of discussions and a lot of research about how big data is impacting the industry, but less attention has been paid to how all the different work in big data fits together, how it is connected,” says Kumar.
For this research, Kumar picked three areas where some of the most interesting and innovative developments in big data are happening. These are areas where massive amounts of data aren’t simply being collected, but that data is also being analyzed and put to use. Take healthcare as an example: As entities across the healthcare space, such as hospital systems, begin to combine their data sets, you can create more intelligence and make better inferences.
“But whenever you have data from many sources, you need smarter systems to read all this data and make sense of it. How can we create algorithms to help doctors make better diagnoses? That requires new and different thinking,” says Kumar.
As researchers learn how doctors use an enormous database of cancer patients worldwide to settle on effective treatment more quickly, experts in the information systems space are racing to find effective ways to work with the massive flood of data like text, photos and video generated by social media use. Meanwhile, operations management experts perfect the algorithms needed to detect fake online product reviews.
“In different industries, people are very siloed. Healthcare people are only worried about healthcare,” says Kumar. Competition has made firms secretive, reluctant to share and combine their data and methods, but this fear often does more harm than good, according to Kumar. “We really need to learn from each other. What would happen if Amazon were more open to learning from how hospital systems use big data and vice versa?”
To that end, his research synthesizes what is already known from research in these three key areas to create a framework for thinking about big data going forward and how these disparate learnings and datasets can be put together for the greater good. “Our research shows that even direct competitors can benefit from sharing data,” says Kumar.
He points out that as data collection devices (including smartphones, smart speakers like Alexa and wearable devices like Fitbit) proliferate and more data-producing machines infiltrate everyday life, business opportunities and challenges will grow. It’s only a matter of time before people live with smart refrigerators that track your calories and driverless cars that know your daily routine and pinpoint your real-time location.
Unless everyone interested in big data learns to share and solve problems together, missed opportunities will continue, costing firms time and money. “Right now a lot of the data being generated from social media and other sources is not being collected or analyzed in a way that makes it meaningful or useful,” says Kumar. His research could change that.
Kumar outlines a proposed framework for mapping big data applications and insights across industries in his recent research paper, “Emergence of Big Data Research in Operations Management, Information Systems, and Healthcare: Past Contributions and Future Roadmap,” published in the journal Production and Operations Management. “The framework essentially provides a breakdown of different topics that have been investigated and what could emerge because of new advancements,” explains Kumar.
Looking to the future, Kumar sees some specific sub-areas of the domains he studied where big data will make an even more significant impact and improvements in business. His proposed future roadmap points to cloud computing, the internet of things and smart cities, predictive manufacturing and 3D printing, and smart healthcare as the likely places big data will flourish most dramatically in the years to come. The possible developments have the potential to change the quality of life for people around the world.
As boundaries between these once discrete domains continue to fade, big data emerges as a powerful common denominator. Up until now, the focus has been on how to get more and more data. But, according to Kumar, the focus must shift into how this data can be combined and analyzed to make sense of it. Without context, the data is little more than ones and zeroes.
“This research is about how can we generate value for the whole society from this data by collecting, analyzing and sharing data,” says Kumar.
“Nano-marketing” is more than just a buzzword—it’s a way for companies to capitalize on the current trend of personalized and authentic marketing.
As the millennial generation has grown—both in size and purchasing power—to be the largest demographic segment in the country, companies are trying hard to gain their attention. “As a whole, this group of 80 million prefers photos and mini-videos that are visually appealing and can be processed quickly,” says Jay I. Sinha, associate professor of Marketing and Supply Chain Management at the Fox School. “That is part of the reason why we’ve seen a tremendous surge in the popularity of visual platforms such as Instagram, Snapchat, Pinterest and YouTube, among others.”
Together with Thomas Fung, assistant professor of instruction, Sinha advises the “Right Way to Market to Millennials.”
Who are Micro-Influencers?
It may seem like everyone is “Insta-famous” these days. Micro-influencers are social media personalities who have cultivated their defined brand and fan base, typically between 1,000 and 100,000 people, with very specific areas of focus.
For example, Melissa Alam, BBA ’10, a brand strategist, shares her recommendations for food and drink locations around Philadelphia. She has cultivated relationships with companies like Starr Restaurants and Drink Nation to arrange giveaways of gift cards and event tickets for her 11,000 followers on Instagram. “I’ve been hired as an influencer and worked with many large brands,” says Alam. “I share all sides of my life so that people can relate to me both online and offline if they meet me in person.”
“Micro-influencers bring credibility and authenticity,” says Fung, “typically due to their extroverted nature, relatability, and genuine passion in some niche field.” In Alam’s case, her followers may see her as a real person with insider knowledge and honest advice. “The internet is full of people showing off lavish lifestyles or reaching unattainable goals for the average person,” says Alam. “It’s so important to stay genuine, authentic and true to yourself and your personal brand if you’re trying to attract an honest following.” The grassroots feeling of this kind of marketing allows companies to address the unique needs of individuals through their relationships with micro-influencers.
Advice to Companies
So what do companies need to know to take advantage of this new kind of marketing?
1. Micro-influencers have their own brands and followers with very specific interests.
“They provide opportunities for companies, big and small, to reach out to narrow and often difficult-to-access sub-populations,” says Sinha. For example, he shares that GE used micro-influencers to help find and recruit female technology specialists for the company.
2. Micro-influencers are accomplished and personable storytellers.
Millennials relate well to storytelling. “The best micro-influencers bring in their own personal narratives that mesh well with the brands they endorse,” says Fung. Micro-influencers have been able to build up their own personal brand by leveraging this skill, so companies should encourage sponsored influencers to incorporate their products or services into their own authentic narrative.
3. Micro-influencers are not direct marketers.
Traditional marketers may feel that the sponsored content is not coming across in an obvious way. But with micro-influencers, their endorsements should never feel forced. “Micro-influencers have finessed the subtle ‘nudge’ into an art form,” says Sinha. He notes that many influencers will refuse to accept relationships with brands or companies that are contrary to their own beliefs or interests, which would damage their credibility with their followers.
Beware of Inauthenticity
The biggest pitfall companies should avoid is appearing inauthentic. Millennials are discerning and skeptical consumers who will turn away quickly from a brand or company that they feel are trying too hard or selling out. “Young, creative micro-influencers know their audience well,” says Sinha. “Let them guide the positioning of the product.”
By diligently finding the right micro-influencer to sponsor, companies of all sizes can cultivate marketing relationships that are interactive, personalized and authentic with the millennial generation.

Sabrina Volpone, PhD ’13, is an organizational diversity expert, researching topics of diversity and identity within the context of race, gender, disability, sexual orientation and immigrant status. Since graduating from the Fox PhD program, her work has been published in peer-reviewed journals such as the Journal of Applied Psychology, Personnel Psychology, and Organizational Behavior and Human Decision Processes.
The On The Verge editorial team had the opportunity to chat with Volpone about how she got started researching the experiences of traditionally under-represented employees, how a more diverse workforce requires organizations to adapt and how they can do better.
How did you become interested in diversity and inclusion?
When I was growing up in Texas, I was not exposed to much diversity. The Dallas/Fort Worth area was very different 30+ years ago then it is now; the only people I knew were white and Christian.
My mom, who had a business degree in accounting and worked for a huge company in Texas, told me a story about how she got fired because she was getting sick at her desk too often when she was pregnant. Her company shrugged it off, saying that they assumed that once she became a mother she would be leaving her job anyway. Hearing these things opened my eyes to small-town values—taking care of your neighbors, for example—being pushed aside when stigmatizing factors were introduced.
Then, when I was working toward my degrees, both my bachelor’s from the University of North Texas and PhD in Human Resource Management from the Fox School, I wanted to do something meaningful that could speak to people’s experiences at work. The research I was seeing did not capture what was going on for women, people of color and other disenfranchised groups.
What are the differences between diversity and inclusion? How does your research incorporate both?
Diversity is more than just checking a demographic box or filling a quota. To really leverage the benefits of diversity we have to talk about inclusion, a separate, but related, topic. The difference has often been illustrated in the following quote from Verna Myers, the vice president of inclusion strategy for Netflix: “Diversity is being invited to the party, and inclusion is being asked to dance.”
In a recent research project, my team went back to basics to investigate how organizations actually define diversity. There are a host of organizations that would like to improve how they are managing diversity because they are facing lawsuits, or simply because they want to be more strategic about managing human resources. There is an increasing need for organizations to collectively rebuild and expand the way we think about these topics.
For example, we looked at the way a few Fortune 500 firms were defining diversity and found that only 38 percent had established definitions on their websites. A large number of those who did listed standard descriptors typically found on HR hiring paperwork that are based on Equal Employment Opportunity (EEO) laws, stating that the company does not discriminate based on age, sex, race, etc. Other companies take a different approach, however, and use language that extends beyond “legal” terminology.
In my work, I am trying to illustrate that diversity and inclusion must work hand-in-hand. The diversity element establishes the organizational environment and the legal mandates required by law. Inclusion facilitates a climate where employees feel valued and included as a result of their unique characteristics. This is important because, as some of my other research shows, leveraging diversity in this way can result in financial gains. We found that one small change in a diversity definition can relate to more than $2 billion in current profits and more than $1 billion in profit growth. Thus, being inclusive when defining diversity results in increased financial outcomes for companies.
How does inclusion impact companies?
To explore the importance of inclusive policies and procedures in the workplace, I was part of a research team that examined the experiences of breastfeeding women in the workforce. We interviewed women in the morning, afternoon and night to see how the quality of their breastfeeding space throughout the day improved work outcomes. The data and quotes from the women illustrated a powerful point: the legal definition of what must be provided (a space to pump that is not a bathroom and is shielded from view) will not make a satisfied, productive employee. When companies provided more than the bare minimum for breastfeeding mothers, we noticed an increase in their work goal progress and their breastfeeding goal progress while also seeing improvements in their work-family balance satisfaction.
How does a more diverse workforce and consumer base require organizations to adapt? How are businesses innovating around majority-minorities, women, people with disabilities, millennials, and other demographics?
Some companies are not, and their workplace cultures and even financials are seeing the impact of that. Many organizations that are not evolving along with their workforce may cease to exist in 10 to 20 years because of their inability to strategically manage their human resources in a way that captures the diversity of their employees.
For example, in a paper that my coauthors and I recently published, we looked at the hiring process for people with concealable stigmas. Specifically, we examined the relationship between applicants disclosing their hearing disability during the interview process and whether or not they received a job offer. Changing our policies and procedures throughout each human resource function to be inclusive of employees with non-visible disabilities is an example of adapting from systems that, historically, have been focused on accommodating employees with visible physical disabilities.
But those who are thinking about the lived experiences of employees, they create policies and procedures that capture that. They are also being strategic through all of their human resources functions—processes like hiring, training and promotions—and are threading the importance of diversity and inclusion practices through all the ways they do business. Executives are making sure that employees are being heard and taken care of. In order for companies to survive, these considerations will become a requirement.

2019 has been an extraordinary year for Sudipta Basu.
In July, Basu was appointed the Fox School’s new associate dean of research and doctoral programs. He was also honored to be named the American Accounting Association’s inaugural Yuji Ijiri Lecturer on Foundations of Accounting. The prestigious lectureship, sponsored by five global accounting associations, recognizes thought leadership from around the world. Basu presented his Ijiri Lecture, “How Robust are the Foundations of the Conceptual Frameworks?” at the annual American Accounting Association meeting in August.
Throughout his career, Dean Basu has established himself as a thought leader and now he will help chart the direction of academic research at the Fox School moving forward. To understand his vision, he discussed the past, present and future of research at Fox.
Can you share a bit about your background? Why were you originally interested in accounting?
I grew up in big cities all over India (Bombay, Madras, Calcutta and Delhi in that order), earning a BA (Honours) in Economics at St. Stephen’s College, Delhi University and an MBA in economics, finance and accounting at the Indian Institute of Management Calcutta. My family members have many PhDs including a grandfather (mathematics), uncles (statistics, history and English) and first cousin (astrophysics), so an academic life was always considered a respectable—and even praiseworthy—choice.
I first studied accounting in grades 9 and 10 and found it quite hard to follow initially. But once I realized how double-entry bookkeeping worked, and that simple algebra revealed the intangible value created by transactions, I was hooked.
What are some of your major goals as dean of research and doctoral programs?
Fox produces lots of high-quality research and one of my main goals is to make our research more visible locally and internationally.
I would also like to collaborate with the Digital Scholarship Center at the Temple library to introduce our students and faculty to new cutting-edge digital tools that could help them stand out in the research world. Most importantly, I want to change our research culture so that we can talk about how our new ideas improve people’s lives and not merely about where they were published. I want to focus on explaining the who, what, when, where, why and how of a particular research project’s impact.
What role has research played in shaping your career?
For me, research is a vocation rather than a career, meaning that I enjoy and value its creativity and life-long learning aspects so much that I largely ignore the future monetary and status rewards. As my wife puts it, I often go to sleep thinking about research and wake up in the morning still thinking about research. I pursue big questions that excite me, such as why accounting exists or what our world would be like if double-entry bookkeeping had not emerged, even if this research cannot be published in our top journals. I am constantly scanning blogs, conferences and journals for questions and tools that I can use in my research, so I am a big consumer of research, not just a producer.
How would you like to see Fox School research evolve in the future?
As its former research director, I strongly support the Translational Research Center’s efforts to make Fox School research more relevant to all our stakeholders—other academics, practitioners, students, policymakers and our local communities. I would like more of our faculty, students, alumni and staff to engage in research and to describe their findings in top academic journals AND in less traditional venues such as op-eds, letters to the editor, blogs, TED talks, undergraduate and practitioner journals, etc. Ultimately, I want Fox School faculty, staff, alumni and students to be more widely regarded as thought leaders in business research.
What role does research play in business schools?
Most business schools promote faculty and student research to increase our shared knowledge. Business schools’ missions usually shape the type of research they support. At research-intensive schools like Fox, rigorous empirical and theoretical research takes pride of place. At teaching-oriented schools, pedagogical and practice-oriented research is valued more than theoretical research.
Where is the largest intersection of research and industry in the future of work?
Researchers dream up the technologies, products, business models and organizational forms of the future. Every technological advance frees people from doing some kinds of routine work, which are delegated to animals, machines, and now computers. The freed-up workers can better use their minds to make higher quality and unique products and services that were too earlier too costly to market.
How can companies work with Fox School researchers?
Companies can learn from the new ideas developed by Fox School researchers and conversely inform them about changing realities in the marketplace. Ideally, we would develop a virtuous cycle wherein firms identify emerging problems, researchers propose alternative solutions, firms try these out in practice and observe how well they work and provide feedback, which in turn lets researchers refine their prescriptions.

As the way we do business evolves faster than ever, leaders need to be prepared. Employees look to their senior executives for confidence, guidance and direction—especially in times of change. But being a leader means nothing unless people choose to follow, and people generally choose to follow those in whom they believe. “It all hinges on the leader’s credibility,” says Lynne Andersson, associate professor of human resource management at the Fox School.
The Power of Perception
Andersson’s previous research started by identifying behaviors that make employees cynical towards their leaders. She identified two key factors in credibility: perceived competence and perceived trustworthiness. Both elements are dependent upon outsiders’ viewpoints—whether or not they believe in the leader’s skills, knowledge, values and dependability.
“These perceptions are extremely important in the digital age,” explains Andersson. With so much information available to be collected and scrutinized, from social networks to artificial intelligence, people may have concerns about who is in control. “Employees want to know that those who are managing them and assessing their performance are competent and trustworthy.”
After having started the research around the question of cynicism, Andersson reversed the point of view. She and her colleagues conducted research studies, gathering feedback from blue- and white-collar workers located all over the country over the course of three years, to identify specific actions that leaders can take to improve credibility with their employees.
Building Credibility, Projecting Competence
Leaders who emphasize the future were seen as the most competent by their employees. “Creating clear plans for future success is different than simply stating a strategic vision or setting performance targets,” Andersson notes. “It involves mapping out, in detail, how the organization will achieve its goals.” Keeping on top of industry trends, predicting upcoming changes and having clear ideas of how to respond to both are other ways for leaders to demonstrate their visions for the future.
Employees value leaders who demonstrate a focus on organizational outcomes but who also attach those outcomes to an individual’s job. “It’s important to convey that an employee’s work affects the whole organization,” Andersson advises. “Employees attribute competence to leaders who can make those connections.”
Competent leaders also look for ways to improve their organization’s operations. “You can consider eliminating unnecessary reporting structures, reducing spending waste, establishing new roles or investing in technology that improves business effectiveness,” Andersson says.
She also advised against putting too much emphasis on credentials. “In our meritocratic world, we love credentials—but people in our study did not equate credentials with competence. Leaders had to prove it through their actions or behaviors, not their resume.”
Proving Trustworthiness
The most important step to take when trying to project trustworthiness is speaking and acting consistently. “To begin, it means making decisions that aren’t contradictory,” says Andersson. “But it also means behaving in a way that aligns with promises, explicit or unspoken.” Leaders should deeply understand all of their stakeholders’ needs in order to prevent potential conflicts.
Leaders that embody the organization’s vision and values are also regarded as highly trustworthy, according to the research. “Employees want to see consistency between the walk and talk.” Andersson encourages senior executives to be mindful of both their professional and personal values, as employees are watching closely to verify authenticity.
According to the research, employees were more trusting of leaders who valued them. “While you may prioritize your employees in your words, make sure that employees are recognized,” says Andersson. “Show how important your employees through things like rewards and plum assignments.”
Insights for Better Leaders
How can senior executives apply this research on the job? Andersson notes that leaders should be cognizant to two main points. First, the good outweighs the bad—sometimes. “When regarding competence,” says Andersson, “people tend to weigh positive information more heavily than negative information.” This means that one competent action may be a good signal of reliability to a leader’s employees. However, the opposite is true for trustworthiness; one dishonest statement or unethical action can make employees lose faith.
Second, restoring credibility is difficult, but not impossible. “To regain lost credibility, leaders must reestablish positive expectations,” Andersson advises. “This means they must repeatedly engage in trustworthy acts since a single act won’t mean much.” By focusing on the actions outlined by Andersson and her colleagues, leaders can slowly build back that relationship.
Credibility in Action
Actions speak louder than words, and according to Andersson, these are the most important things leaders should do to increase their credibility amongst employees.
What Do Competent Leaders Do?
- Emphasize the future
- Prioritize employees
- Take action and initiative
- Communicate effectively
- Gain knowledge and experience
What Do Trustworthy Leaders Do?
- Communicate and act in a consistent manner
- Protect the organization and employees
- Embody the organization’s vision and values
- Consult with and listen to key stakeholders

“If you see something, say something.” As intuitive as it may seem, speaking your mind is hard—especially within the boundaries of an office environment. Most employees face the fear of retaliation and the social costs that come with speaking up to management in difficult situations.
Leora Eisenstadt, assistant professor of Legal Studies, and Deanna Geddes, professor of Human Resource Management at the Fox School, delve deeper into these emotional situations in their interdisciplinary studies. The researchers discuss the implications of expressing anger at the workplace and highlight two problematic legal doctrines that disincentivize employees from making any complaints—thus costing companies.
A Cycle of Discontentment
When employees suppress anger at work, it not only affects their mental well-being but also their attitudes—often resulting in lowered productivity. “When employees fear the consequences of retaliation by management,” says Geddes, “they tend to either suppress it by keeping silent, or express their frustration to their peers, who usually have no power to respond or effect change.” These negative discussions often spiral into increasing discontentment among employees that impact the overall health of the workplace.
Reactions vs. Retaliation
In the face of perceived discrimination, employees may turn to the courts for help in resolving disputes. However, Eisenstadt argues that current legal frameworks may negatively affect employees’ willingness to speak up in the judicial system. Currently, judges use the following two legal doctrines in an effort to promote consistency across similar cases but frequently end up disenfranchising employees.
- The “Objectively Reasonable Belief” doctrine protects only those employees who complain about behavior that the courts would regard as unlawful. Given that employees do not typically understand the nuances of court decisions, this may make employees hesitant to come forward because they are unsure if their complaint will be protected by the law.
- The “Manner of the Complaint” doctrine supports employers who claim the reason for firing an employee was the ‘inappropriate’ way in which the complaint was raised, without serious consideration to the details of the complaint itself.
Eisenstadt argues that the consequences of these court-created approaches are clear. “Employees, upon seeing how these doctrines play out for their co-workers, choose to keep silent,” she says. This not only hinders the goals of the law, which is meant to protect employees from workplace discrimination but the culture and worker productivity at the workplace also suffer.
A Call For Change
Not all emotions at work lead to discord, says Geddes. “Psychological research demonstrates that expressions of anger to management in any form—whether it be in respectful complaints or in emotional outbursts—is healthier and more productive for both the worker and the workplace overall.”
So what happens next? The researchers advise that companies build a culture of open dialogue within their organizations to promote expression up and down management lines. Nonhierarchical, team-based structures, leadership’s encouragement of meaningful debate and clear channels for expressing opinions all help employers address emotions while the employee is still in the workplace.
Eisenstadt and Geddes also suggest that the court system rethink its implementation of the existing retaliation doctrines. They propose that the judiciary take an approach that considers the circumstances that led to retaliation and view the scenario from all relevant perspectives, not just the employers. “This more global approach would undoubtedly create a greater sense of security in employees,” says Eisenstadt.

Will robots replace humans at work?
As technology evolves, this question has been on the minds of many. For repetitive jobs, some are already automated. But managers and supervisors, whose jobs require higher levels of cognitive ability, should be safe—right?
Xue Guo and Zhi Cheng, two doctoral students in the Fox School’s Department of Management Information Systems, studied how the new technologies like TaskRabbit, a leading online platform to find immediate help for everyday tasks, have affected managerial-level jobs.
In analyzing data from the housekeeping industry, Guo and Cheng found a 2.9 percent decrease in the total number of offline full-time workers after the platform’s introduction—a drop mainly driven by a decrease in the number of frontline supervisors and managers.
Effects of Digital Management
The evolution of the gig economy—and the subsequent digital platforms—has created new opportunities for those searching for work. ‘Gigs’ allow people to be more selective about the employers they want to work for, receive relatively higher pay and choose from a field of work options. Even employers enjoy the flexibility of recruiting extra help as needed, reducing fixed labor costs and presenting them with options for specialized skills.
So how do these platforms change the rules of the workplace, especially for management?
To answer that question, the researchers integrated data from TaskRabbit, the Bureau of Labor Statistics and the Census Bureau, aiming to better understand the impact of the gig economy for routine cognitive workers versus manual workers.
“After the entry of TaskRabbit,” says Guo, “we observed a 5.5 percent decrease in first-line managerial jobs.” Manual workers, such as cleaners and janitors, were not as affected. This suggests that the platform mostly affected middle-skill management, whose primary tasks were to arrange and schedule service in the housekeeping industry.
Managers Moving to TaskRabbit
TaskRabbit reduced the demand for offline managers in the industry by directly connecting some of the tech-savvy cleaners to their clients. According to Guo, the detailed information about clients’ requirements and workers’ qualifications “allows them to connect with each other at lower search costs.”
Not all managers who left the industry were replaced by robots, however. Supervisors who were skilled in using technology could move to these digital platforms, giving them more freedom in an online role. “On TaskRabbit, managers could recruit and supervise regular cleaners more efficiently,” reasons Guo. “The platform also provided more flexibility and autonomy, incentivizing them to move online.”
Laborers Grapple with Technology
The researchers found that TaskRabbit increased the productivity of manual workers by efficiently planning schedules, monitoring their performance and solving disputes, subsequently driving market demand. The platform also attracted workers of different skills and backgrounds while increasing labor supply and accessibility by reducing the barriers of entry to get a job.
Laborers could also take advantage of the options for flexibility and mobility. “We observed that, even though the number of jobs has reduced, we could see an increase in self-employed workers,” says Guo. “Later studies may look at the actual wage differences, but TaskRabbit can support the option of self-employment of both managers and laborers.”
Learning To Keep Up
Thanks to technological changes like these, the dynamics of the traditional workplace are continuing to shift. Generalizing to other industries, Guo mentions that these platforms increase productivity and allow for more efficient business models, but may come at a cost to the less computer literate.
The researchers, however, are positive about this emerging economy in the future of work. “The barrier to entry of TaskRabbit is not very high,” says Guo. While this skills-biased technology change is happening in the workplace, it can create new opportunities—particularly for those entrepreneurial workers willing to learn.

More than 15 million adults struggle with alcohol addiction. In fact, according to the CDC, one in ten deaths of working-age adults in America is linked to alcohol. That’s one reason data on alcohol use has been chosen by researchers for study from the enormous data set from the U.S. Department of Veterans Affairs’ ambitious Million Veteran Program (MVP). The VA intends as the project’s name states, to gather data on an astonishing one million service members.
Kuang-Yao Lee, assistant professor of statistical science at the Fox School, sees a world of potential new knowledge in this vast cache of data. This is particularly true of alcohol use because the data from the MVP is longitudinal, which means the same measurements are tracked over time. Alongside the support from the VA, Lee’s project received funding through from Office for the Vice President of Research at Temple University.
Volunteers in the MVP each submit blood samples as well as health surveys, amassing a dataset that comprises both genetic data and behavioral patterns. Beginning in 2016 when he was a researcher at Yale University, Lee and his colleagues have been using this information-rich resource to search for the specific combination of genes that correspond to alcohol and other substance use.
“Previous studies have suggested [these genes exist], but mostly were only limited to small scales or restricted conditions,” says Lee. “We want to use statistical models to find out if this is really a valid assumption. Our results so far suggest a very strong association.”
While ample electronic health records and genetic data have long been available to researchers, only recently has the efficient computing power become available to slice and dice the information into accurate, usable new insights and discoveries. More sophisticated algorithms combined with larger-than-ever computer storage capacity, as well as parallel computation techniques, allow today’s researchers to make meaning from a huge amount of complex data.
How huge? “Depending on the facility, the whole genome sequencing [for one person] can produce hundreds of millions of variants,” says Lee. Questionnaires allow researchers to gather large amounts of information about each subject every time they are administered. Multiply that by one million veterans. “We’re talking about not just billions, but millions of millions of points of data,” he says.
Data with this level of complexity can lead to findings that are more nuanced and reliable than in the past. Previously statistics sometimes led to oversimplified and other not-quite-right conclusions. We’ve all heard the old axiom, “There are three kinds of lies: lies, damned lies, and statistics.” But as so-called big data increases in scope and complexity and the tools used to analyze this data become more sophisticated, statistics are becoming more honest than ever before. From projects such as the Million Veteran Program and other similarly vast datasets, new genetic truths may ultimately emerge.
There are many possible real-world applications for this research. For one thing, determining which specific genes are linked with alcohol and other substance abuse could lead to new and better medicines and treatments for the very veterans who have volunteered their most sensitive personal information for this work. A dialed-in genetic profile that indicates a vulnerability for substance abuse could be used to screen kids and even adults while there is still time for effective early interventions that can keep them on a healthy path. Given the current public health crisis around opioids, alcohol, and other substance use, a breakthrough of this kind could have far-reaching benefits.
Lee says that the knowledge gleaned from the Million Veteran Program about substance abuse may lead to similar projects that could help solve other vexing behavioral, health, and genetic puzzles. He also notes that the innovative statistical models and tools he’s used in this research could be applied in myriad ways to other complex datasets.
For example, online shopping platforms can easily observe huge amounts of individual consumers and, at the same time, collect data across large numbers of variables. “One of the core problems in business analytics is to use statistical models to study the inter-dependency between observed variables, for example, the dependency between decision making and consumer behavior,” Lee says.
“There are a surprising number of similarities between genomics and online shopping.”

Sometimes ideas for academic research can come from the unlikeliest of places. Like out of your earbuds.
Hilal Atasoy, assistant professor in the Department of Accounting at the Fox School, was hardly expecting to discover a subject that would lead to years of study while listening to a podcast, but that is exactly what happened.
“I was listening to a story about a cancer patient,” says Atasoy. In addition to being physically and emotionally difficult, having cancer can be costly. The patient explained that during her treatment she had moved and had to change hospitals and doctors several times because of her relocation and other reasons.
“She was saying how difficult it was to keep transferring her tests, results, procedures, and other records. She had to go through this ordeal again and again,” recalls Atasoy. Finally, the patient landed at a hospital with a good electronic health records (EHR) system, and she didn’t need to go to any extra trouble or expense anymore.
That got Atasoy thinking. Since the HITECH Act of 2009 made the migration of patient information from paper files to electronic health records mandatory, many studies have investigated whether this shift actually benefits hospitals, as electronic health records systems are costly to implement.
The results of previous research, particularly around healthcare costs, have been inconclusive. Studies point to the likelihood that costs actually go up—not down—as electronic health records systems are put into practice, at least for the individual hospital in question. But Atasoy’s research looks beyond the adopting hospital to the region surrounding it. “The question we’re asking in the study is whether the impacts of the electronic health records go beyond the adopting hospital.”
It’s common for someone to have a dermatologist at one hospital, get a mammogram at a different hospital, and see a primary care doctor affiliated with a yet a third institution, especially if that person lives in a city. When you factor in the costs at not only the individual hospital that adopted EHRs but also the costs at surrounding hospitals where there are shared patients, Atasoy has found that there is a marked cost-saving benefit after all. Estimates suggest that if one hospital in each area adopts an EHR system, it would add up to a net reduction of $18 billion in healthcare costs nationwide.
To conduct her research, Atasoy relied on several data sets. “We tracked information about the adoption of electronic health records systems at almost all the hospitals in the U.S. from 1998 to 2012,” she says. She also used Medicare data, census data, and HIMSS data (a dataset that comprises information about EHR use across the country). Atasoy and her team used statistical analysis software to interpret the numbers and come to their conclusions about the costs and benefits of EHR beyond the walls of any one hospital. Her research was published last year in the journal Management Science.
Atasoy notes that implications for her research extend beyond the healthcare sector. “It shows the importance of connections across different organizations. Businesses might be connected, for example, through shared customers,” she says. “Obviously, the firms are focused on their customers and their purchases and all the information they have on their customers right within their business, but there are many organizations that share customers or share suppliers. They have these connections.”
Her work on hospital-level data led into her current research, which focuses on patient-level data and seeks to identify the cost and quality of care benefits that could come with the widespread sharing of EHR between health institutions. “We’ve learned that only 20 percent of doctors use electronic health records, and what we’ve seen suggests that there are significant benefits to patients when doctors do use them,” says Atasoy. This seems to be especially true for patients living with chronic conditions such as cancer, diabetes, or heart disease.
Atasoy hopes her research will help spark a discussion about the value of hassle-free information reciprocity at hospitals, something that, on a policy level, she believes needs to be incentivized. Just as she began to look at the bigger picture, viewing hospitals regionally as a group and not individually, viewing a patient’s multi-year health journey and not just a single procedure, she hopes hospital administrators will zoom out, too.
“One big problem with healthcare in the United States is that it’s very fragmented,” says Atasoy. Her work reveals that a hospital isn’t an island and that the free flow of information will ultimately benefit everyone’s bottom line.

Victor H. Gutierrez-Velez never expected his work to lead him to the topic of public health. His expertise lies in remote sensing science, analyzing data such as satellite images. “Every day, numerous satellite images are taken,” says Gutierrez-Velez. And the information drawn from these images has both academic and commercial applications.
For example, satellite images can help prescribe management, fertilization, irrigation, and other activities in precision agriculture, according to Gutierrez-Velez. They can help the insurance industry assess risks related to flooding or other natural disasters, or to verify crop insurance complains. Satellite imagery can allow energy companies to pinpoint the ideal location for solar panels. And this kind of data, it turns out, can even come in handy when it comes to fighting certain diseases.
To that end, partnering with colleagues with expertise in biology and public health, Gutierrez-Velez, assistant professor in the College of Liberal Arts, has recently been drawn to an unlikely research subject: mosquitoes. Specifically, the tiger mosquito (scientific name: aedes albopictus). What’s so interesting about this tiny, blood-sucking bug?
“It’s worrisome. They can spread the Zika virus and other dangerous diseases,” says Gutierrez-Velez.
In 2016 when the Zika pandemic caught his interest, mosquitoes dominated the headlines. Once thought to be limited to tropical and subtropical regions, the tiger mosquito had expanded its territory into most continents. Climate change plays a role, but these mosquitoes are also particularly aggressive. They’re among the 100 most invasive species in the world. In the 1980s, they were first spotted in the U.S. in Texas. Today, they reach as far north as Connecticut. Their presence in Pennsylvania remains an ongoing public health concern.
For his project, a recipient of the Office for the Vice President of Research‘s Targeted Grant Program and supported by the Data Science Institute housed at the Fox School, Gutierrez-Velez decided to look at multiple datasets, including climate data, information gathered from sampling for the presence of the tiger mosquito, land cover data, and census information. Gutierrez-Velez believes that with these and other datasets as inputs, machine learning and advanced algorithms can be used to predict the locations of tiger mosquito populations in advance of the season.
One of the most interesting possible findings of this research is that the tiger mosquito is less of a rural dweller than previously thought. “What we’re finding contradicts conventional wisdom about where these mosquitoes live. They are becoming domesticated animals. They prefer to be where lots of humans are living closely together—in cities. Because they love our blood,” says Gutierrez-Velez.
Scientific curiosity led Gutierrez-Velez to census data, which is not necessarily an obvious source of information to predict the presence or absence of a small flying bug. “If they feed on humans, human behavior should have something to do with it,” he says. And it does seem like including this data makes for a more accurate prediction about where the mosquitoes will go next.
Gutierrez-Velez’s ultimate goal for the project is to perfect a reliable working model that can be used to predict the upcoming mosquito season. Knowing that a particularly bad mosquito season is about to start will give officials the opportunity to plan in advance.
For example, the most affected areas can be targeted for treatment before the problem becomes unmanageable. Residents could be strongly cautioned in advance of the season to deal with housing-related conditions, such as places that collect standing water, which act as mosquito breeding areas. In the event that mosquitoes are spreading Zika or another virus, these protections could even save lives.
“There’s a lot we can do if we have a model that can say, ‘Hey, it’s going to be a bad year for mosquitoes, get ready,’” says Gutierrez-Velez.

A personalized touch can make all the difference.
When you log into Amazon, Netflix, or Facebook, one of the first things you see are recommendations for products, shows, or friends you may know—all based on things you have already bought, watched, or liked.
Recommender systems have eliminated the time-consuming effort of understanding and anticipating what exactly users want, sometimes before they know they want it. Using vast collections of detailed data points, data scientists can create a trail of digital breadcrumbs, which follows Internet users as each sale, search, and interaction becomes part of an algorithm for new suggestions. These platforms can predict and encourage your next shopping sprees, binges, and bucket lists.
In the private sector, companies have long been using technology-enhanced learning in order to proactively suggest and anticipate their consumers’ choices. But how can these mechanisms be most effectively applied to academia?
“We have to learn something new every day,” says Dr. Konstantin Bauman, assistant professor in the Management Information Systems (MIS) Department at the Fox School of Business. “With the traditional path, we go to university, take some courses, meet with the instructor once a week, and go to lectures. But today, there are many different types of tools and materials available online that are able to educate large groups in a personalized and direct way.”
Educational companies like Coursera, Lynda.com and the Khan Academy already use recommender systems to suggest courses their users may like, based on their history. Bauman, however, wanted to know whether personalized e-learning can help students struggling to comprehend a particular subject.
“Education is one important application of recommender systems for society to target materials for specific learning paths,” says Bauman.
Bauman, along with co-author Alexander Tuzhilin of New York University’s Stern School of Business, examined the personalized e-learning systems approach with the help of a tuition-free online university. By using curricula from 42 classes and test results from 910 students over three semesters, the researchers created a system to pinpoint—and address—specific areas within a student’s comprehension that needed improvement.
The team reported their findings in the paper, “Recommending Remedial Learning Materials to Students by Filling Their Knowledge Gaps,” which was published in MIS Quarterly in 2018.
In this real-life experiment throughout the 2014-2015 academic year, Bauman’s team identified where students’ knowledge waned and provided materials to supplement these gaps. “Instead of revising the entire lesson, we provided catered lessons to fill those gaps,” says Bauman.
The students had diverse backgrounds, from both the United States and developing countries, and studied in a variety of programs, from business to computer science to art history. The researchers split the students into three groups: a control group that received no recommendations, a group that received non-personalized recommendations, and a group that received recommendations tailored to the individual student.
Bauman and his team created taxonomies that mapped all the topics covered within a specific course, built a library of remedial learning materials, and matched test questions with course topics. After analyzing test scores, the researchers identified the students’ weaknesses. The students in the non-personalized group received generic recommendations for the course, while students in the personalized group received remedial materials for specific topics that were identified via testing.
“First, we showed that most of the students who received our recommendations found them relevant and helpful,” says Bauman. Second, the “average” students, who received a test score between 70 and 90 in previously taken courses, were most affected by personalized recommendations. “These students improved their performance on the final exams significantly more, in comparison to their prior performance before they received personalized recommendations than the students from the control group.” For this subset of students, the personalized group received an average grade of 83.22 in their final exams, while the control group scored an average of 79.39.
The study received limited interactions with students who were classified as “falling behind” (those whose previous grade averages were below 70) as only six students who received personalized recommendations actually clicked on the materials. Similarly, students who were “excellent” (with average grades above 90) were less likely to need remedial lessons.
Bauman found that, by determining specific materials needed to supplement their understanding, students saved time and energy in preparation for their exams.
“Learning systems have the capability of picking up patterns and behaviors that can clearly predict necessary methods that are worthwhile and timely,” says Bauman. For students and professors, time that may be used to teach a specific lesson can be accomplished through recommender systems, saving more time for interactions that encourage new ideas and understandings.
One thing is for sure—when it’s time to come back for more, a new suggestion will be waiting.

Meet NAO.
NAO came to Temple University about three years ago, when Li Bai and Carole Tucker, researchers from the Colleges of Engineering and Public Health, and, joined Heidi Grunwald, director of Temple’s Institute for Survey Research, to study robotics and surveys.
The team wanted to explore a big idea: What if NAO, this cute, two-foot tall, human-ish robot, could be programmed to give health surveys to children on the autism spectrum? Could they create a system to collect patient-reported outcomes in this tough-to-survey population?
Potentially, this research could solve a number of difficult problems. Currently, its parents fill out surveys on behalf of their kids. Researchers would prefer patient-reported outcomes. It’s much more accurate than information filtered through a third party, such as a parent. “Kids with autism may be willing to say they are depressed, but not in front of their mother,” says Tucker. When a one-foot-tall robot with a cute robotic voice such as NAO is asking questions instead of a human clinician, researchers might get reliable patient-reported outcomes in a way they have not been able to in the past.
The team’s research would also include another stream of valuable information: para-data. The camera inside the robot would “watch” the subject as NAO asked the survey questions. Additionally, via the sensor the subject wears (a Microsoft wristband), researchers can monitor things like facial expression, heart rate, and body motion. This para-data is a rich vein of knowledge, particularly when combined with the survey questions, response time, and answers.
If the subject pauses an extra long time when a certain question is asked, the NAO can play a game (like rock, paper, scissors), take a break, or give a high five to reduce anxiety. This is one way that the robot uses para-data to adapt to a child’s answers. The para-data also helps the researchers better understand survey responses. “For example, we can tell if a particular question made a subject nervous and then down-weight the answer, or not count it,” explains Grunwald.
“The robot’s face is much less complex than a human face and human facial expressions,” says Tucker. That makes it much less overwhelming for a young person on the autism spectrum who may find it challenging to read people’s faces and maintain eye contact.
Their project received funding through the Office for the Vice President of Research’s Targeted Grant Program at Temple University, with matching funds from all three represented schools.
Planning the research has been an iterative process. On the computer science side, Bai and his engineering students have been exploring the feasibility of using NAO this way. Bai and the students have been answering questions like, “What features would be nice? How can we use sensors to pull in data and incorporate the Microsoft band?” They have iterated and refined the data architecture, a database where the data are meshed together so that the robot can read all of the survey response data–coupled with the para-data (sensor data).
Meanwhile, the questionnaire and para-data collection process have been tested on different groups, starting with older kids not on the autism spectrum. As trial subjects, children aged 10 and up can provide specific, meaningful feedback on interacting with NAO. More recently, a community event brought a group of children on the autism spectrum to campus, and the team had an opportunity to see NAO interact with the intended study subjects. Going forward, they have the kind of pilot data that can win the funding to drive this effort forward.
This work can benefit groups beyond younger people on the autism spectrum. Any time data reported directly from a patient may be skewed or inaccurate—such as dementia patients, for example—the survey methods used in this work could prove enormously helpful to clinicians.
“With future improvement in this type of research, I think we will see more robotic diagnostic platforms that will be developed. One of the functionalities will be surveys of the patients about their health conditions. It could be particularly important for people who can not find a good hospital in their neighborhood,” says Bai.
Practical applications of this work in the future aren’t limited to the realms of research and medicine by any means. “Artificial intelligence and robotics will be the next technology push to drive the economy of our country, There will be countless business world applications—such as personal robotic assistants (such as the iPhone’s Siri) or self-driving cars,” says Bai. He believes that the technology in this project will fuel innovations across all sectors of the economy in the years to come.
