Research Interests:
Juvenile Delinquency; Community and Crime; Child Abuse; the Family; Research Methodology; Quantitative Data Analysis MethodsBiography:
Dr. Xiaoli Su has been an assistant professor in the Department of Criminal Justice at Troy University since August, 2012. She joined the Troy University after her graduation from the Department of Sociology at the University of Georgia, Athens, GA. She started her study at U.G.A. in 2005 and was awarded M.A. in sociology in 2007. She was awarded Ph.D. in Sociology in 2012 with specialty in Crime, Law, and Deviance. Before coming to the U.S., she had studied at the Chinese People's Public Security University in Beijing, P. R. China and was awarded LL.M. (Master of Laws) in 2002. During her graduate studies, Dr. Su has developed strong research interests in the etiology and prevention of juvenile delinquency. She has also done research on the relationship between community characteristics and crime in communities.

Currently, Dr. Su is interested in a number of research areas: the etiology and prevention of juvenile delinquency, criminal rehabilitation, fear of crime, and gender and crime. For the prevention of juvenile delinquency, she is working on a hand-on approach to build better family environments for youths. In her research, Dr. Su has found that parents with multiple problems are more likely to have poor parenting behavior. All these problems seem to point to inadequate education of parents in home economics - parents are not prepared to be adequate parents. Dr. Su is working on a project to examine how home economics education is related to parents' efficacy. Through this project, Dr. Su hope to be able to call for more emphasis on home economics education in public education system. Public education should focus on cultivating new generations of adequate family members, parents, and citizens, not just good workers for employers.

In the area of criminal rehabilitation, Dr. Su has questioned the "nothing works" assertion about criminal rehabilitation. Dr. Su argues that the failure of criminal rehabilitation programs does not mean the failure of criminal rehabilitation. The key element of criminal rehabilitation, unconditional love/acceptance to criminals as individuals while punishing their criminal behavior, is missing from criminal rehabilitation programs. Dr. Su is working on a manuscript and hope to call for changes in public policy to build a more tolerant environment facilitating criminal rehabilitation.

In the areas of fear of crime and gender issues, Dr. Su has examined the fear of crime among a special population – single-mothers with underage children. Single-mothers with underage children shoulder the responsibilities as primary caregivers as well as family providers, victimization can be especially costly for them. Testing the vulnerability hypothesis, Dr. Su has examined whether single-mothers with underage children are more likely to report fear of crime, comparing to the general population. The result shows support for the hypothesis. Dr. Su calls for special attention to this population from law enforcement agencies in providing better protection for communities.

Dr. Su has presented her work in criminology and criminal justice conferences at both regional and national levels. Her two articles in the area of juvenile delinquency have been published in a peer-reviewed journal - Journal of Youth and Adolescence.

Robert Mathis is a lecturer at Troy University's global campus site in Albany, Georgia. He has been teaching there full time since 2007. The primary discipline in which he teaches is in Criminal Justice. A main strength of Robert lies in his experience. He has served almost 33 years in the law enforcement field in various positions. From police officer to corrections officer, Robert has first hand in depth knowledge of different positions and functions. One major advantage is that Robert taught 14 years in the Public Safety Training Division for the State of Georgia. This experience greatly enhances his teaching ability with University students.

Robert graduated Capella University from Minneapolis Minnesota, with Distinction for a perfect 4.0 average, with a Ph.D. in Public Safety. He received a Master's of Science degree in Public Administration Justice Field from Columbus State University in Columbus, Georgia. Also, he received his B.S. degree in Criminal Justice from Columbus State University. However, Robert has the honor of graduating from Georgia's Law Enforcement Command College at Columbus State University.

As a faculty member, Robert teaches a wide range of Criminal Justice courses. Currently, he teaches mostly in undergraduate courses. His main course is the Research class for undergraduate students. However, Robert will teach any course from Introductory courses to Senior Capstone courses. His experience, when communicated in class rooms, helps students to understand behind-the-scene principles of law enforcement operations. This enables students to comprehend both sides, academically and operationally, of criminal justice functions.

His research interest lie in polices and processes of law enforcement. Robert's dissertation engaged one of Georgia's sensitive issues of firearms recertification. In a time of budget cuts, information and statistical results showed flaws in thinking for reducing budget money for firearms skills training. This has led several local agencies to rethink their current polices with firearms recertification courses and scheduling. His current research investigates gender differences for some agency functions.
