CSDE Workshops

Join CSDE Workshops: “Introduction to Survey Data Sources” and “Agent Based Modeling in R”

CSDE is offering two workshops on “Introduction to Survey Data Sources” (02/24) and “Agent Based Modeling in R” (03/05). Students, faculty, and staff are all welcome to register for our workshops and we welcome registrants from outside the University of Washington as well. If you miss a workshop, recordings will be available on our website for 3 months after the workshop. To register, click here.

CSDE Training Director  and Research Scientist Dr. Christine Leibbrand will lead the workshop on February 24th on accessing some major American demographic survey data sources. Participants will learn about a variety of longitudinal survey data sources that are (for the most part) publicly-available and easily accessible. These data sources will include: The National Longitudinal Survey of Youth 1979 (NLSY79) and its Child Supplement (CNLSY); The National Longitudinal Survey of Youth 1997 (NLSY97); Fragile Families and Child Wellbeing Study (FFCWS) and The Panel Study of Income Dynamics (PSID). Topics covered include their sampling strategies, the characteristics of their survey populations, the years they surveyed populations, an overview of the data included in these surveys, and an introduction into how to access and download the publicly available data and access restricted data. By the end of this workshop, participants will have a better understanding of longitudinal survey data sources that you might consider using for your future research projects. Dr. Leibbrand is uniquely qualified to offer this workshop, as she has analyzed and published analyses using all of these data sources.

CSDE Research Scientist Dr. Deven Hamilton will lead the workshop on March 5th on agent-based modeling in R. The workshop will  provide a basic introduction to Agent-Based Modeling (ABM) and will be divided into three sections. The first section will review and discuss the basic elements of ABMs and their application in a variety of fields including demography, sociology, anthropology, political science and public health. The second section of the course will work through examples of an ABM and reproduce the models in R. Finally, the workshop will discuss an example of a complex ABM using the statnet and EpiModel R packages. By the end of the workshop, participants will be able to describe the unique features of ABM that make them distinct from other modeling approaches, write R functions to produce a simple ABM, and be familiar with additional R packages that provide functionality for ABM.

Godwin and Wakefield Publish Research on Space-Time Modeling of Child Mortality in LMICs

CSDE Fellow Jessica Godwin and CSDE Affiliate Jon Wakefield just published their research on “Space-Time Modeling of Child Mortality at the Admin-2 Level in Low and Middle Income Countries Context” in Statistics in Medicine.  Their work demonstrates innovative approaches in statistical methods for estimating child mortality when data are sparse or variably observed at different levels of aggregation and collected through different methodologies. They extend earlier work to provide estimates at the Admin-2 Level so as to improve information for targeted interventions to reduce child mortality. In the paper they describe four extensions to previous work: (i) combining summary birth history (SBH) data with first birth history (FBH) data, (ii) modeling on a yearly scale, to combine data on a yearly scale with data at coarser time scales, (iii) adjusting direct estimates in Admin‐2 areas where we do not observe any deaths due to small sample sizes, (iv) acknowledge differences in data sources by modeling potential bias arising from the various data sources. The methods are illustrated using household survey and census data from Kenya and Malawi, to produce mortality estimates from 1980 to the time of the most recent survey, and predictions to 2020.

Marquez and Wakefield Publish New Research on Innovative Methods for Harmonizing Child Mortality Data Across Disparate Geographic Levels

CSDE Fellow Neal Marquez and CSDE Affiliate Jon Wakefield recently published “Harmonizing Child Mortality Data at Disparate Geographic Levels” in Statistical Methods in Medical Research. The authors present a new method for analyzing masked survey data, using an approach that is consistent with the data-generating process. In addition, they critique two previously proposed approaches to analyzing masked data and illustrate that they are fundamentally flawed methodologically. To validate their method, they compare their approach with previously formulated solutions in several realistic simulation environments in which the underlying structure of the risk field is known. They simulate samples from spatiotemporal fields in a way that mimics the sampling frame implemented in the most common health surveys in low- and middle-income countries, the Demographic and Health Surveys and Multiple Indicator Cluster Surveys. In simulations, the newly proposed approach outperforms previously proposed approaches in terms of minimizing error while increasing the precision of estimates. The approaches are subsequently compared using child mortality data from the Dominican Republic where their findings are reinforced. The ability to accurately increase precision of child mortality estimates, and health outcomes in general, by leveraging various types of data, improves our ability to implement precision public health initiatives and better understand the landscape of geographic health inequalities.

Nur and Co-Authors Publish Article on Behavior Adoption Approaches During Public Health Emergencies

CSDE Trainee Aasli Nur and co-authors recently published a practice article in BMJ Global Health titled “Behavior Adoption Approaches During Public Health Emergencies: Implications for the COVID 19 Pandemic and Beyond.” The authors  draw from the emerging evidence on behavior adoption during diverse public health emergencies to develop a framework that contextualizes behavior adoption vis-à-vis a combination of top-down, intermediary and bottom-up approaches. Using the COVID-19 pandemic as a case study, they operationalize the contextual framework to demonstrate how these three approaches differ in terms of their implementation, underlying drivers of action, enforcement, reach and uptake. They illustrate how blended strategies that include all three approaches can help accelerate and sustain protective behaviors that will remain important even when safe and effective vaccines become more widely available. They conclude that as the world grapples with the COVID-19 pandemic and prepares to respond to (re)emerging public health threats, a contextual framework can inform the design, implementation, tracking and evaluation of comprehensive public health and social measures during health emergencies.

Rothschild, Drake, and Brown Provide Commentary on Unmet Need Measurement
In a recently published commentary for Studies in Family Planning, CSDE Trainee Claire Rothschild (Epidemiology, PhD), CSDE Regional Affiliate Win Brown (Bill & Melinda Gates Foundation), and CSDE Affiliate Alison Drake (Global Health) make the case for including observations from method discontinuation measures to update current approaches to measuring unmet need for contraception. While unmet need for contraception is commonly used to assess programmatic needs, it inadequately captures the complexity of fertility and contraceptive preferences, including women's satisfaction with their contraceptive method. In their 2019 commentary, Sarah Rominski and Rob Stephenson propose reclassifying dissatisfied current users as having an unmet need for contraception. As revising the current definition based on their proposal would require significant investment to update survey and monitoring systems, understanding the potential impact on current estimates of unmet need is critical. The authors estimate the impact of this approach in a Kenyan cohort of modern contraceptive users. They find the prevalence of method dissatisfaction ranges from 6.6% (95% confidence interval [CI] 5.6–7.8%) to 18.9% (95% CI 17.1–20.9%); if applied nationally, this results in a large (approximately 25–70%) increase in Kenya's current estimate of unmet need for any contraception. The findings suggest a large impact on unmet need estimates for equivalent populations. Overall, the authors advocate for better measurements of method satisfaction and acceptability, with metrics developed that are robust to socioeconomic gradients and validated in low‐ and middle‐income settings to ensure women's contraceptive needs are captured equitably.

*New* James S. McDonnell Foundation – Understanding Human Cognition Awards [Due 04-09-2021]

Applications are open for the James S. McDonnell Foundation’s 2021 grant program ($250k in seed funding over a flexible time period (2-4 years). Proposals are due Friday, April 9, 2021. This program aims to support projects leading to new conceptual and empirical studies of cognition and behavior that recognize the dynamic nature of cognition and behavior, are situated in real world contexts, cross levels of analysis, unite traditionally separate domains of inquiry (e.g. vision and speech), embrace complexity, and consider how behavior is influenced by interactions among individuals. Priority will be given to applicants requesting funds to support collaboration or to obtain training that allows new theories and new tools to alter the conduct of ongoing research, to provide a researcher with supported time while acquiring the new skills and knowledge to alter future research design, to pilot or test novel experimental approaches and to allow laboratories primarily using artificial laboratory constrained tasks to explore behavioral studies with more natural free flowing behaviors, to refine and extend the temporal dimension of data acquisition allowing for more dynamic assessments of how behavior unfolds over time and to diversify and expand study populations. Application instructions can be found at the  Foundation's website. If you’re considering applying please feel free to reach out to CAS Corporate & Foundation Relations for support. CSDE is always happy to help you in the preparation of your applications - whether that is with scientific consultations or pre-award proposal support, which includes budget preparation, all ancillary materials, management of submission, and experienced reviewers for providing feedback on your narrative.
