Georgia Southern Examines Kernel Density Estimation

Kernel density estimation is probably the most widely used non parametric statistical method for estimating probability densities. In this paper, we investigate the performance of kernel density estimator based on stratified simple and ranked set sampling. Some asymptotic properties of kernel estimator are established under both sampling schemes. Simulation studies are designed to examine the performance of the proposed estimators under varying distributional assumptions. These findings are also illustrated with the help of a dataset on bilirubin levels in babies in a neonatal intensive care unit.

On kernel density estimation based on different stratified sampling with optimal allocation,” was recently published in Communications in Statistics – Theory and Methods.

Dr. Hani Samawi, Professor of Biostatistics at the Jiann-Ping Hsu College of Public Health Georgia Southern University (JPHCOPH) was the lead author, Drs. Jingjing Yin and Haresch Rochani, Assistant Professors of Biostatistics were two of the co-authors.


Georgia Southern Faculty Named APHA Social Worker of the Year

Dr. Joseph Telfair, Chair and Professor of Community Health at the Jiann-Ping Hsu College of Public Health and President Elect of the American Public Health Association, has recently been named as this year’s recipient of the Insley-Evans Public Health Social Worker of the Year by the Award’s Committee of the Public Health Social Work Section of the American Public Health Association for his many years of service to the field of public health social work, his research contributions to the fields of adolescent health, and his record as an academic administrator. A reception will be held in his honor during the Association’s annual meeting.

This award is named for two leaders in the field, Virginia Insley and Juanita Evans, who both played significant roles in the founding of public health social work education, research, and services. Virginia Insley was the first Chief Social Work Officer for the Maternal and Child Health Bureau. She served from 1955 to 1980 and Juanita Evans succeeded her, holding the position from 1980 to 2000.


Georgia Southern Assesses Individuals’ Perceptions of their Income Sufficiency

Assessing individuals’ perceptions of their income sufficiency (i.e., subjective income) is important for theoretical and practical reasons. Despite the well-documented association between health status and income, we know little about the relationship between health status and self-perceived income sufficiency. An improved understanding of the relationship between how people think about their income and their objective income addresses fundamental behavioral economics issues, including questioning the assumed association between low income and perceived income insufficiency. On the practical side, for individuals reluctant to reveal their income level, self-perceived income sufficiency may serve as a palatable proxy for objective income. This study presents a dynamic approach to collecting income information. We conducted a cross-sectional survey of 2,022 residents of historically underserved Appalachian Kentucky, an ideal location due to pervasive low income and our ability to control for potential confounders such as race/ethnicity and residential heterogeneity. In unadjusted analyses, nearly half of the sample indicated they struggled to meet their needs; 43% said they made just enough to get by; and 10% indicated they had more than they needed to live well. Adjusting for socio-demographic characteristics, proportionately more of those with lower self-rated health and a higher number of morbidities reported struggling to make ends meet. Less than 1% refused to respond to the question on self-perceived income sufficiency, compared with 20% who refused to report income levels. We conclude that self-perceived income sufficiency is a useful question to assess resources, both theoretically and practically, in an underserved population.

Self-perceived Income Sufficiency and Self-reported Income Level among a Health Inequity Population,” was recently published in the Journal of Health Care for the Poor and Underserved.

Dr. Yelena Tarasenko, assistant professor of epidemiology at the Jiann-Ping Hsu College of Public Health Georgia Southern University was the lead author. Dr. Nancy E. Schoenberg, associate dean for research at the college of public health at the University of Kentucky was the co-author.


Georgia Southern Faculty Assess Disease Intervention Specialist Education for the Future

Georgia Southern assesses alignment of two accredited public health curricula with Disease Intervention Specialist (DIS) tasks and knowledge. The articulation of standardized competencies targeting DIS is of utmost importance.  DIS standardized credentialing is more important now than ever before given focused attention on intervention, disease surveillance due to emerging disease threats such as Zika and H1N1, and the successful continuous quality improvement movement for standardization through the work of the Public Health Accreditation Board (PHAB).

The DIS workforce, largely employed within local and state public health departments, serves as a vital component in assuring the health of the public.  There are an estimated 1,661 DIS (1,404 filled positions) within the nation’s current workforce and 400 DIS supervisors.  A comprehensive job task analysis was recently completed by PSI Services, LLC, through a collaborative agreement between the Public Health Accreditation Board (PHAB), the National Association of County and City Health Officials (NACCHO), the National Coalition of STD Directors (NCSD), and the Centers for Disease Control and Prevention (CDC).  This job task analysis served as the foundation for the mapping of public health course content with DIS tasks and knowledge criteria completed in this analysis.

Four research faculty conducted a gap analysis utilizing eleven core BSPH courses and six core MPH courses, and identified gaps with DIS task and knowledge statements. Recommendations were based upon these identified gaps and future strategies to address these gaps.

Dr. Bill Mase, assistant professor of health policy and management, Dr. Andrew Hansen, assistant professor of community health, Dr. Stacy Smallwood, assistant professor of community health, Dr. Gulzar Shah, department chair of health policy and management, and Ms. Angie Peden, assistant director of the center for public health practice and research at the Jiann-Ping Hsu College of Public Health Georgia Southern University worked closely with Dr. Kaye Bender, president and CEO of the Public Health Accreditation Board on the commissioned paper.


Henderson Library presents ‘A Chinese Art Preview’

The Zach S. Henderson Library will honor the life and art of Jiann-Ping Hsu, Ph.D., and explore the history of Chinese art and calligraphy at ‘A Chinese Art Preview’ on Wednesday, July 12, from 2 – 3 p.m. in Library Room 1300.

The event will be hosted by the Library’s Special Collections, and will feature some of the beautiful works of Hsu and the many works of art she collected. In addition to being the namesake of the Jiann-Ping Hsu College of Public Health, Hsu was a scholar, scientist and artist who devoted her career to public health before losing a long battle with cancer in 2004. She served with the Food and Drug Administration, served in the leadership of several pharmaceutical companies, and was a research consultant with Biopharmaceutical Research Consultants, Inc., a research consulting organization founded by her husband, Karl E. Peace, Ph.D. Peace endowed the College of Public Health in her name as a celebration of her life.

Light refreshments will be provided at the event.
