SUMMARY:Nathaniel Osgood\, University of Saskatchewan
DESCRIPTION:The UCLA Department of Community Health Sciences and the Center for Social Statistics presents:\nDynamic Modeling for Health in the Age of Big Data\nTraditional approaches to public health concerns have conferred great advances in the duration and quality of life. Public health interventions – from improved sanitation efforts\, to vaccination campaigns\, to contact tracing and environmental regulations – have helped reduce common risks to health throughout many areas of the world. Unfortunately\, while traditional methods from the health sciences have proven admirably suited for addressing traditional challenges\, a troubling crop of complex health challenges confront the nation and the world\, and threaten to stop – and even reverse the – rise in length and quality of life that many have taken for granted. Examples include multi-factorial problems such as obesity and obesity-related chronic disease\, the spread of drug-resistant and rapidly mutating pathogens that evade control efforts\, and “syndemics” of mutually reinforcing health conditions (such as Diabetes and TB; substance abuse\, violence and HIV/AIDS; obesity & stress). Such challenges have proven troublingly policy resistant\, with interventions being thwarted by “blowback” from the complex feedbacks involved\, and attendant costs threaten to overwhelm health care systems. In the face of such challenges public health decision makers are increasingly supplementing their toolbox using “system science” techniques. Such methods – also widely known as “complex systems approaches” – provide a way to understand a system’s behavior as a whole and as more than the sum of its parts\, and a means of anticipating and managing the behavior of a system in more judicious and proactive fashion. However\, such approaches offer substantially greater insight and power when combined with rich data sources. Within this talk\, we will highlight the great promise afforded by combining of Systems Science techniques and rich data sources\, particularly emphasizing the role of cross-linking models with “big data” offering high volume\, velocity\, variety and veracity. Examples of such data include fine-grained temporal and spatial information collected by smartphone-based and wearable as well as building and municipal sensors\, data from social media posts and search behavior\, helpline calls\, website accesses and rich cross-linked databases. Decision-oriented models grounded by such novel data sources can allow for articulated theory building regarding difficult-to-observe aspects of human behavior. Such models can also aid in informing evaluation of and judicious selection between sophisticated interventions to lessen the health burden of a wide variety of health conditions. Such models are particularly powerful when complemented by machine learning and computational statistics techniques that permit recurrent model regrounding in the newest evidence\, and which allow a model to knit together holistic portrait of the system as a whole\, and which support grounded investigation of between intervention strategies tradeoffs. \nSponsored by The Department of Community Health Sciences along with the Center for Social Statistics and the California Center for Population Research \nSpeaker:\nNathaniel Osgood\, Professor\, Department of Computer Science\, Associate Faculty at Department of Community Health & Epidemiology and Bioengineering Division at the University of Saskatchewan

SUMMARY:Shahryar Minhas\, Duke University
DESCRIPTION:The Center for Social Statistics Presents:\nPredicting the Evolution of Intrastate Conflict: Evidence from Nigeria\nThe endogenous nature of civil conflict has limited scholars’ abilities to draw clear inferences about the drivers of conflict evolution. We argue that three primary features characterize the complexity of intrastate conflict: (1) the interdependent relationships of conflict between actors; (2) the impact of armed groups on violence as they enter or exit the conflict network; and (3) the ability of civilians to influence the strategic interactions of armed groups. Using ACLED event data on Nigeria\, we apply a novel network-based approach to predict the evolution of intrastate conflict dynamics. Our network approach yields insights about the effects of civilian victimization and key actors entering the conflict. Attacks against civilians lead groups to both be more violent\, and to become the targets of attacks in subsequent periods. Boko Haram’s entrance into the civil war leads to an increase in violence even in unrelated dyads. Further\, our approach significantly outperforms more traditional dyad-group approaches at predicting the incidence of conflict.\n  \nSpeaker: \nShahryar Minha\, Postdoctoral Fellow\, Duke University\nAssistant Professor\, Michigan State University\nDepartment of Political Science and the Social Science Data Analytics Program (SSDA) \nhttp://s7minhas.com/

SUMMARY:Ilan H. Meyer & Mark S. Handcock\, UCLA
DESCRIPTION:The Center for Social Statistics Presents:\n\n\nInnovative Sampling Approaches for Hard to Reach Populations: Design of a National Probability Study of Lesbians\, Gay Men\, Bisexuals\, and Transgender Peoples and  Network Sampling of Hard to Reach Populations\nSpeakers: \nIlan H. Meyer\, Williams Distinguished Senior Scholar for Public Policy at the Williams Institute \nMark S. Handcock\, Professor of Statistics at UCLA and Director of the Center for Social Statistics \nDescription: \nCome for the exciting seminar then stay for the free lunch and discussion. A seminar led by Ilan H. Meyer followed immediately by a Brown Bag Lunch led by Mark S. Handcock. \nDr. Meyer is Principal Investigator of the Generations and TransPop Surveys. Generations is a survey of a nationally representative sample of 3 generations of lesbians\, gay men\, and bisexuals. TransPop is the first national probability sample survey of transgender individuals in the United States. Both studies attempt to obtain large nationally representative samples of hard to reach populations. Dr. Meyer will review sampling issues with LGBT populations and speak on the importance of measuring population health of LGBTs and the underlying aspects in designing a national probability survey. \nFrom a contrasting perspective\, the field of Survey Methodology is facing many challenges. The general trend of declining response rates is making it harder for survey researchers to reach their intended population of interest using classical survey sampling methods. \nIn the followup Brown Bag Lunch\, led by Mark S. Handcock\, participants will discuss statistical challenges and approaches to sampling hard to reach populations. Transgenders\, for example\, are a rare and stigmatized population. If the transgender community exhibits networked social behavior\, then network sampling methods may be useful approaches that compliment classical survey methods.\nParticipants are encouraged to speak on ideas of statistical methods for surveys.

SUMMARY:Rick Dale\, University of California\, Merced
DESCRIPTION:The Center for Social Statistics Presents:\nQuantifying the dynamics of multimodal communication with multimodal data\nAbstract: Human communication is built upon an array of signals\, from body movement to word selection. The sciences of language and communication tend to study these signals individually. However\, natural human communication uses all these signals together simultaneously\, and in complex social systems of various sizes. It is an open puzzle to uncover how this multimodal communication is structured in time and organized at different scales. Such a puzzle includes analysis of two-person interactions. It also involves an understanding of much larger systems\, such as communication over social media at an unprecedentedly massive scale. \nCollaborators and I have explored communication across both of these scales\, and I will describe examples in the domain of conflict. For example\, we’ve studied conflict communication in two-person interactions using video analysis of body and voice dynamics. At the broader scale\, we have also used large-scale social media behavior (Twitter) during a massively shared experience of conflict\, the 2012 Presidential Debates. These projects reveal the importance of dynamics. In two-person conflict\, for example\, signal dynamics (e.g.\, body\, voice) during interaction can reveal the quality of that interaction. In addition\, collective behavior on Twitter can be predicted even by simple linear models using debate dynamics between Obama and Romney (e.g.\, one interrupting the other). \nThe collection\, quantification\, and modeling of multitemporal and multivariate datasets hold much promise for new kinds of interdisciplinary collaborations. I will end by discussing how they may guide new theoretical directions for pursuing the organization and temporal structure of multimodality in communication. \nUrl: http://statistics.ucla.edu/seminars/2016-03-31/2:30pm/314-royce-hall

SUMMARY:Betsy Sinclair\, Washington University in St Louis
DESCRIPTION:The Center for Social Statistics Presents:\n\n\nElectronic Homestyle: Tweeting Ideology\nAbstract: Ideal points are central to the study of political partisanship and an essential component to our understanding of legislative and electoral behavior. We employ automated text analysis on tweets from Members of Congress to estimate their ideal points using Naive Bayes classification and Support Vector Machine classification. We extend these tools to estimate the proportion of partisan speech used in each legislator’s tweets. We demonstrate an association between these measurements\, existing ideal point measurements\, and district ideology. \n

SUMMARY:Reproducibility of Statistical Results
DESCRIPTION:The Center for Social Statistics Presents:\n\n\nMark S. Handcock \n(Professor\, Statistics) \nJeffrey B. Lewis \n(Professor\, Political Science) \nMarc A. Suchard \n(Professor\, Biomathematics\, Biostatistics and Human Genetics) \nAbstract: \nReproducibility is one of the main principles of the scientific method. This panel of scholars will discuss issues in the importance of replication of statistical results. Increasing attention is being paid to improve reporting and hence reproducibility in the social and medical sciences. This panel will discuss some key concerns in study replication\, initiatives for increasing replication\, and then open the floor to discussion of how we move forward as a scientific community.

SUMMARY:Aude Hofleitner\, Facebook
DESCRIPTION:The Center for Social Statistics Presents:\nInferring and understanding travel and migration movements at a global scale\nAbstract: Despite extensive work on the dynamics and outcomes of large-scale migrations\, timely and accurate estimates of population movements do not exist. While censuses\, surveys\, and observational data have been used to measure migration\, estimates based on these data sources are constrained in their inability to detect unfolding migrations\, and lack temporal and demographic detail. In this study\, we present a novel approach for generating estimates of migration that can measure movements of particular demographic groups across country lines. \nSpecifically\, we model migration as a function of long-term moves across countries using aggregated Facebook data. We demonstrate that this methodological approach can be used to produce accurate measures of past and ongoing migrations – both short-term patterns and long-term changes in residence. Several case studies confirm the validity of our approach\, and highlight the tremendous potential of information obtained from online platforms to enable novel research on human migration events. \nIf you are interested in meeting with or joining the speaker for lunch\, please send email to Seminars@ccpr.ucla.edu

SUMMARY:Bayesian Statistical Modeling Using Stan
DESCRIPTION:The Center for Social Statistics Presents:\n\nInstructor: Daniel Lee\, Columbia University\n\nAbstract:\nStan is an open-source\, Bayesian inference tool with interfaces in R\, Python\, Matlab\, Julia\, Stata\, and the command line. Users write statistical models in a high-level statistical language. The default Bayesian inference algorithm is the no-U-turn sampler (NUTS)\, an auto-tuned version of Hamiltonian Monte Carlo. Stan was developed to address the speed and scalability issues of existing Bayesian inference tools. The goal of the workshop is the practical application of Stan to different models starting with ordinary linear regression and ending with more complex models such as generalized linear mixed and hierarchical models. Experience in Bayesian statistical modeling is recommended\, but not required. Workshop participants should bring their own laptop installed with RStan (or some other Stan interface). See http://mc-stan.org/ for instructions on how to install it.\n\nThe workshop is open\, but UCLA community members are especially welcomed.  To enroll for the workshop\, please go to: http://goo.gl/forms/CYHSj8Vkcw\n\nThe workshop is co-sponsored by the UCLA Department of Statistics\, the UCLA Department of Political Science\, and the Department of Biostatistics at UCLA.
