The Purpose of Pilot Studies in Modern Research

Course Objective

  • Describe the cons of estimating effect sizes from pilot studies.
  • Contrast the cons of using pilot studies for power computations with pros of using the clinically meaningful estimate.
  • Describe the purpose of pilot studies in modern research.

Presenter:
Martina Pavlicova, PhD, MS
Associate Professor of Biostatistics
Columbia University Medical Center


In this webinar, participants learn from Dr. Martina Pavlicova about the benefits and limitations of pilot testing in clinical research. First, Dr. Pavlicova uses a case study to provide a comprehensive review on hypothesis testing, random sampling, and data stratification. Since effect size and sample size effect power, participants learn that pilot studies have limited statistical significance. Dr. Pavlicova explains how piloting is still essential to clinical research when determining feasibility, acceptability, safety, and tolerability of a study.

Introduction to Qualitative Analysis with ATLAS.ti
Person Writing on Sticky Notes

Course Objective

  • Critically interpret the meaning of textual data using inductive reasoning
  • Develop a preliminary classification scheme using interpretative reading
  • Categorize inferences with meaningful conceptual labels and/or codes
  • Formulate conclusions based on relationships between established categories and/or codes
  • Perform basic qualitative analysis techniques in ATLAS.ti software, including:
    • Prepare primary documents for importing into ATLAS.ti’s Hermeneutic Unit
    • Generate output of coded textual data
    • Troubleshoot key importing, coding and output operations in ATLAS.ti

New York City-Long Island-Lower Tri-County Public Health Training Center with revisions made by the Region 2 Public Health Training Center


Qualitative research produces rich, narrative data that requires both analysis and interpretation. In this section, learners are guided through the basic steps of the analysis process: Organize, Reduce, and Describe. An interactive practice exercise accompanies each step. Following this discussion, ATLAS.ti is introduced as a computer assisted software package that can supplement and improve pen and paper coding processes. Users follow instructional videos to learn how to use ATLAS.ti to manage large bodies of textual, graphical, audio, and video data. It is recommended that users download a trial version of ATLAS.ti software to follow along with the instructional videos in Part III and to practice at home. Download a trial version of ATLAS.ti.

Public Media Data for Public Health

Course Objective

  • Describe public media data available for disease surveillance
  • Describe public media data available for audience segmentation
  • Describe public media data available for message design and tailoring

Date: July 10, 2018

Presenter:
Dr. Joe Smyser, PhD
CEO
Public Good Projects


This webinar explores new ways to use public media data to solve large, complex public heatlh issues like opioid abuse and mental health. Dr. Joe Smyser explains how the Public Good Projects uses data from Facebook, Google, and designated market areas (DMAs) to create insights about a population’s health knowledge, attitudes, and beliefs in real time to inform public health media campaigns. Participants of this webinar will be exposed to case studies of how this data was used to create tailored messages for specific populations about opioids and mental health using digital marketing principles.

The City Health Dashboard: A New Resource for Population Health Improvement

Course Objective

  • Describe the role of data in improving population health in urban areas
  • Describe how data on health status and health determinants improve cross-sector collaboration and decision making around health
  • Explain how the City Health Dashboard can be improved to be a more effective tool for health improvement

Date: May 1, 2018

Presenter:
Shoshanna Levine, MPH, DrPH
Program Director
City Health Dashboard


Over two-thirds of the U.S. population lives in cities. There is currently a shift for city governments to work with multi-level stakeholders to use a population health approach to target social determinants of health and improve the overall quality and health of the population. Dr. Soshanna Levine discusses the importance of using data as a cross-sectional, collaborative health improvement approach. The Department of Population Health at NYU Langone Medical Center and the Robert F. Wagner School of Public Service at NYU partnered with national networks to create the City Health Dashboard to help cities understand, compare, and take action to improve the health of their municipalities. The tool uses data from federal, state, and local agencies to present 36 measures linked to the health status across five domains (health behaviors, clinical care, social and economic factors, physical environment, health outcomes). The dashboard is a health improvement planning resource for 500 cities across the U.S. and will also provide evidence-based interventions and resources to city leadership, government, and stakeholders. Dr. Levine presents an overview of the dashboard and methods to engage local communities in data-driven health improvement activities.

Using Geographic Information Science to Advance Health Equity and Environmental Justice
Hand of Geography Layout

Course Objective

  • To describe how geographic information science can be used to advance health equity and environmental justice.
  • To describe the environmental factors that lead to health disparities.
  • To list examples of how geographic information science has been used in health equity research.

Date: May 2, 2017

Presenter:
Andrew Maroko, PhD
Associate Director
Lehman College Urban GISc Lab
CUNY Graduate School of Public Health and Health Policy


Environmental factors have an important impact on the health of communities. Public health professionals may use geographic information sciences (GIS) to assess the health of communities by analyzing exposure, or being subjected to negative factors such as pollution, as well as accessibility, or the ability to access positive factors such as green space and healthy food. In this webinar, Dr. Andrew Maroko discusses the process of geovisualization, hypothesis generation, data exploration, and communication and knowledge transfer in conducting environmental justice research. Dr. Maroko also describes various methods and technologies used to estimate exposure and accessibility, and provides examples of GIS in environmental justice/health equity projects in New York City and Glasgow, Scotland.

A Few Thoughts on Spatio-Temporal Epidemiology
Spatio Temporal Epi

Course Objective

  • Discuss why temporal data are becoming increasingly part of spatial analyses
  • Explain why statistical analyses are important as opposed to merely visualizing patterns
  • Discuss benefits and drawbacks of using aggregated vs. point data in spatial analysis
  • Describe a couple examples using mobile population data in epidemiologic analyses

Date: May 29, 2014

Presenter:
Jaymie Meliker, PhD
Associate Professor
Preventive Medicine at Stony Brook Program in Public Health


Employing techniques of spatial statistical analysis can provide important insights in research studies. In this webinar, Dr. Jaymie Meliker provides a historical perspective on GIS, spatial software tools, and spatial data; describes the importance of space-time data and software; argues why spatial statistical analysis is important; and explains examples of cluster analyses of early and late stage breast cancer, cancer clusters in case-control residential histories, and space-time exposure reconstruction over the life-course.
