Title: Peer Network Processes in Adolescents' Health Lifestyles

Abstract: Identity-based lifestyles offer individuals a lens by which to make behavioral decisions, thereby serving to reproduce social inequalities. But how do such lifestyles come about and change over time? We argue that friendship networks have a role in lifestyle development, while also being a product of lifestyles themselves. In particular, we examine the relationships between friendship networks and health lifestyles— interrelated health behaviors arising from group-based identities. We suggest that modeling influence and selection processes for lifestyles rather than for specific health behaviors resolves theoretical and empirical limitations in studies of network and behavior change. Using Add Health data, we analyze two high schools with repeated friendship network data. Latent class analyses characterize each school’s predominant health lifestyles based on several health behavior domains. School-specific stochastic actor based models (SABM) evaluate the bidirectional relationship between friendship networks and health lifestyles. We find that predominant lifestyles differ across schools, but remain stable within schools over time, even as individuals transition between lifestyles. The findings also demonstrate that the similarity of health lifestyles among friends results primarily from selection, but also from influence processes.

Title: Rocky Mountain Dreaming: Undocumented Young Adults in Colorado​

Abstract: About 2 million undocumented immigrants are members of the 1.5-generation, meaning they came to the United States as children and remain here without a pathway to citizenship. Legal status shapes nearly every facet of their lives, from their educational participation to their sense of belonging. Drawing from survey and in-depth interview data from the ongoing CO Deferred Action for Childhood Arrivals (DACA) study, this talk examines how the lives of undocumented young adults in Colorado, a re-emergent immigrant destination, varies by where one lives and grows up, or place. More specifically how are undocumented young adults in rural and urban contexts navigating different opportunities, resources, and challenges.

Jean-Frédéric Morin, Associate professor, Université Laval, Québec, Canada

Abstract: Trade agreements increasingly include ambitious environmental provisions. Despite the encompassing nature of these provisions, studies on their drivers and consequences remain scarce. Until recently, the main factor hindering research in this area was the lack of reliable data. This presentation will discuss a new dataset, the Trade & Environmental Database (TREND). This dataset documents 280 types of environmental provisions in 680 trade agreements signed between 1947 and 2016. The database is of particular relevance for research on institutional design, legal innovation, regime complexity, policy diffusion, and treaty effectiveness

Bio:  Jean-Frédéric Morin is a senior fellow with CIGI’s International Law Research Program (ILRP), effective May 2016. He is also associate professor at Laval University, where he holds the Canada Research Chair in International Political Economy.

At CIGI, Jean-Frédéric is contributing to the ILRP’s research themes on international intellectual property, and environmental and economic laws by building a large database, sponsored by the Canadian Foundation for Innovation, CIGI and Laval University. This database will document institutional interactions among trade, investment and environmental institutions. It will enable Jean-Frédéric and other CIGI researchers to study the emergence, variation, diffusion, implementation and effectiveness of hundreds of different provisions found in thousands of multilateral, regional and bilateral agreements.

Before being invited to hold the Canada Research Chair in International Political Economy, Jean-Frédéric was a professor at Université libre de Bruxelles from 2008 to 2014, and a post-doctoral researcher at McGill University from 2006 to 2008.

Jean-Frédéric has an interdisciplinary training in law and political science, and has taught in law programs as well as in political science programs. He is currently conducting research in the fields of trade policy, investment law, global environmental politics, and international intellectual property law, with a particular interest in studying how transnational networks shape the interactions of international institutions.

Title: The Labor Market Effects of Immigration Enforcement.

Abstract: We examine the effects of a large, federal immigration enforcement policy–Secure Communities (SC)–on the labor market outcomes of both citizen and non-citizen workers. 450,000 individuals were deported under SC, 96% of whom were male. We use the county-by-county rollout of SC to estimate a difference-in-difference model. We find that SC decreased the employment of low-skilled male non-citizen workers and negatively impacted the employment of male citizens in middle to high-skill occupations. The evidence suggests this spillover effect onto citizens is due to complementarities in production across skill groups. This is the first quasi-experimental evidence on the labor market effects of immigration enforcement policies on citizens, which is of paramount importance given ongoing immigration policy debates.

Bio: Hani Mansour is an Associate Professor in the Department of Economics at the University of Colorado Denver. He received his Ph.D. from the University of California at Santa Barbara in 2009.

Title: Children's Technology Use, Health Lifestyles, and the Reproduction of Inequality.

Abstract: Relatively little is known about children’s technology use in the mobile technology era or about how current patterns of technology use relate to other aspects of health lifestyles, such as physical activity or sleep, in early life. Technology use is a rapidly evolving and highly prevalent health behavior. Information about its long-term effects is sparse and mixed, and parenting norms around it are in flux. Stefanie Mollborn will present results in progress from a mixed-methods, NSF-funded project that combines nationally representative survey and time diary data on health lifestyles and technology use across the early life course with multimethod qualitative data following families with elementary-aged children as the children transition into middle school.

Bio: Stefanie Mollborn is a Professor in the IBS Health & Society Program and the Department of Sociology, and is training director at IBS. She studies norms and social inequalities in the early life course. Her work focuses on the U.S. context and combines statistical analyses of longitudinal population surveys with qualitative analyses of in-depth interviews. She received a Ph.D. in Sociology from Stanford University in 2006. Her 2017 book, Mixed Messages: Norms and Social Control Around Teen Sex and Pregnancy, is available from Oxford University Press. Mollborn’s most recent mixed-methods research continues a focus on social norms in the case of health lifestyles among children and teens, with a particular emphasis on their use of technology in the mobile internet era.

Title: Finding Jobs, Forming Families, and Stressing Out? Work, Family, and Stress among Young Adult Women in the US

Abstract: The transition to adulthood is increasingly characterized by complex paths into work and family, especially for women. How work and family combine to influence stress among young adult women is not well-understood. In this presentation, I describe how new extensions to latent class analysis (LCA) can help identify common combinations of work and family circumstances among young adult women and investigate implications for stress. Two stress measures are examined – perceived stress and a biomarker for stress-related immunity dysfunction, Epstein-Barr Viral (EBV) antibody titers. LCA models identify seven common combinations of work-family circumstances, ranging from well-compensated professional work in the absence of children to mothers without paid employment. Results from the BCH Step-3 extension to LCA show that perceived stress is higher among mothers and childfree women in unskilled work with low wages and decision-making freedom than their counterparts in skilled “white-collar” work with higher wages and decision-making freedom. These differences are attenuated after adjustments for several measures of poverty-related stress. EBV antibody titer values did not vary across the work-family typology. These findings suggest that the benefits of combining work and family may be limited to women of higher socioeconomic status, as prior research suggests.

Bio: Adam Lippert is a sociologist and demographer whose work focuses on three themes: (1) how work and family circumstances are associated with stress-related pathologies in young- and mid-adulthood; (2) how neighborhood and school contexts influence health; and (3) how economically-vulnerable families manage risks and protect their children’s health and development. He is Assistant Professor of Sociology at the University of Colorado Denver.

Title: "Immigration Attitudes and Government Compensation"

Abstract: Do compensation programs increase support for immigration among less educated citizens, who are some of the most vulnerable to economic openness within the developed democracies? This paper considers several arguments about how compensation might influence immigration attitudes, including the unfortunate proposition that compensation efforts may even induce less educated citizens to feel more negatively about their class identity, pushing them towards a social identity based more on the nation with greater hostility towards immigrants as national outsiders. Using cross-national survey data, it reports that greater national-level compensation can indeed be associated with less supportive immigration attitudes for the least educated citizens. This negative effect diminishes for more educated citizens, but it never becomes positive. Using a population-based sample of voting-age Americans, randomly presented with an informational vignette about U.S. compensation programs describing them as extensive, targeted towards the poor and racially inclusive, it also reports a conditional negative impact on immigration attitudes among those who were treated. The compensation treatment has a significant negative effect on immigration support for those with the least education, which weakens for those with more education.

Title: Agglomeration and Human Networks in History

Abstract: Recent work in complex systems suggests aggregate properties of human settlements are network effects; specifically, they are outcomes of an equilibrium that develops as people arrange themselves in space so as to balance the benefits of interaction with the costs of movement. This balancing act leads to open-ended and predictable allometries between settlement population and a variety of aggregate quantities, from settled areas to infrastructure needs to socioeconomic rates to the division of labor. Importantly, these allometries are observable in societies organized at all scales, across the world, and throughout history. In this talk, I introduce the ideas and models of settlement scaling theory, review its supporting evidence from urban geography, archaeology and history, and highlight its potential for building a predictive theory of human society.

Abstract: The 2018 Kīlauea eruption, which began on May 3 and paused on August 5, is the longest and largest recent eruption in the lower Puna district of Hawaii. Over 700 homes were destroyed and frequent seismicity and deformation at the summit caused damage to the USGS Hawaiian Volcanoes Observatory as well as to critical infrastructure within the Hawaii Volcanoes National Park. To support the Department of the Interior (DOI) and state and county authorities in response to the eruption, the USGS activated the DOI Strategic Sciences Group (SSG). Established in 2012, the SSG is designed to complement ongoing response efforts by providing strategic science to identify potential social, environmental, and economic consequences and potential interventions of a crisis event affecting Departmental resources. This was the first official activation of the SSG since it supported Hurricane Sandy recovery in 2013. From July 17-19, 2018 the SSG convened a multidisciplinary team of 13 experts to examine the short- and long-term social, economic, and environmental cascading consequences of the eruption to DOI resources, employees, and facilities as well as to the surrounding communities. The SSG Kīlauea team developed three scenarios focused on the impacts of 1) continued seismicity and deformation at the summit; 2) vog; and 3) the eruption in the Lower East Rift Zone. This presentation will provide an overview of the SSG methods, initial results of the Kīlauea scenario-building process, identified knowledge gaps, and potential actions that were identified to mitigate cascading consequences.

Title: It’s About Time: Evidence on Time Use in Full-Versus Half-Day Preschool Contexts

Abstract: High quality early childhood education (ECE) programs can alter children’s life trajectories and yield substantial social returns. One promising approach to realizing social benefits from ECE investments is through improvements to their quality and intensity. The current research project adds to the small existing literature by providing new experimental evidence about the impacts of full-day preschool, on a host of immediate- and medium-term outcomes in a small, predominantly low-income, non-White, and ELL district near Denver. Prior to 2016, this district provided only half-day preschool. In 2016-2017, the district created nine new full-day classrooms as part of a Full-Day Pre-K Pilot Program, and since then we have randomized two cohorts of applicants to these full-day slots or the business-as-usual half-day slots. Cohort 1 exhibited large effects on academic and socio-emotional outcomes by the end of the preschool year. Assuming that we continue to find evidence of positive effects of full-day preschool offers, the next policy-relevant question is about how the additional time in school is used, relative to how it would have been used in the absence of the full-day option.

Bio: Allison Atteberry is an assistant professor in the Research and Evaluation Methodology (REM) program, within the CU-Boulder School of Education. She received her Ph.D. in 2011 from the Stanford School of Education in educational policy analysis, with a minor in statistics. Dr. Atteberry conducts research on teacher- and school-level interventions designed to improve the quality of instruction experienced by historically underserved students. As a field, we are increasingly aware of how difficult it is to determine whether policies, practices, and interventions have the intended impacts, and so Dr. Atteberry approaches her work with a strong interest in what constitutes compelling evidence of causal effects in quantitative research. In terms of methods, Dr. Atteberry teaches and uses both econometric and statistical approaches to education policy analysis. Dr. Atteberry’s academic interests center on policies and interventions that are intended to help provide effective teachers to the students who need them most. This has led her to focus on the identification, selection, development, and retention of teachers who have measurable impacts on student achievement.

Title: Understanding Absenteeism in Elementary School: Results from an RCT embedded qualitative study

Abstract: Chronic truancy – missing 5% or more of the days of a school year – has been on the rise in Chicago’s Public Schools (CPS). In this talk I will briefly share results from a large-scale randomized controlled trial of Check & Connect, a structured monitoring and mentoring program focused on student engagement with school, that was implemented in CPS in 2011-2013. The focus of the talk will be on understanding why elementary school students in an urban context miss school. I will explore what students and their families report in terms of reasons for missing school and the home, school, neighborhood, and contextual factors that likely influence school attendance among this population.

Bio: Mimi Engel is an associate professor in the Research and Evaluation Methodology (REM) program in the CU-Boulder School of Education. Through her research, Dr. Engel aims to contribute to our understanding of how policies and programs affect children’s developmental outcomes and opportunities to learn. Her interest in studying how schools and other contexts influence students is informed by her training in human development and social policy and social work. Spanning several areas including teacher labor markets (focus on teacher hiring), early skill formation (focus on mathematics teaching and learning for young children), and contextual influences on children, the central aim of her research is to provide new information about policies, programs, and administrative factors that have the potential to improve students’ school-related outcomes, particularly among students from traditionally under-served populations.
