Abstract:

The geography of Latinx areas of residence in the U.S. has shifted dramatically in the last three decades, with the Latinx population  increasingly living in urban, suburban, and rural areas outside of established immigrant gateways such as California and Texas. This project addresses the consequences of the geographic diversification of Latinx settlement in the U.S. for patterns of health and well-being among the Latinx population. Amidst the changing geography of Latinx settlement, one question of interest is whether emerging areas of Latinx settlement, including “new” and “other” areas of settlement, have more positive or negative contextual resources and intergroup relations related to health and well-being than established gateways. In this ThinkSpatial talk, I present initial exploratory results from an assessment of variation in health care resources and immigration enforcement policies across three types of Latinx counties: 1) Established Destinations; 2) New Destinations, and; 3) Other Destinations. I draw from an array of publicly-available data sources, including the U.S. decennial censuses, the Health Resources and Services Administration (Area Health Resource Files, Health Professional Shortage Areas data, and Medically Underserved Areas data), the Robert Wood Johnson Foundation (County Health Rankings and Roadmaps), and the Migration Policy Institute and Immigrant Legal Resource Center (287g program participation information). This work has important implications
for the current COVID19 pandemic, as it reveals the types of communities where Latinx populations may be lacking health care resources and where they may face contextual barriers to accessing health care.

Liz Ackert is an Assistant Professor in the Department of Geography at the University of California, Santa Barbara. Her research interests include racial/ethnic inequality, immigration, education, health disparities, urban geography, and quantitative methods. Her work examines
explanations for why racial/ethnic and immigrant-origin groups are unequally distributed across contexts– including schools, neighborhoods, and immigrant destinations– and evaluates the consequences of this contextual inequality for disparities in outcomes in domains such as education, residential mobility, and health. Dr. Ackert is particularly interested in understanding how the attributes of immigrant-receiving contexts, including states, communities, neighborhoods, and schools, influence the health and well-being of Latinx  children and youth.

11:30 a.m. (PST) Tuesday, May 5, 2020

Zoom* : https://ucsb.zoom.us/j/98445704485

Abstract:
The occurrence of crime depends on a multitude of factors, namely crime attractors or generators, and it shows high spatiotemporal complexity. This presentation is targeting two opposite crime perspectives: (1) objective crime, and (2) subjective crime – perceived crime safety – fear of crime. This work contributes to the research on environmental crime analysis and prediction by pursuing two objectives. The  first one is to uncover spatial relationships between crime occurrences and nearby social media activity, whereas the second one to estimate the possible influence of social media posts on crime prediction models. The focus of this part of the presentation is on sporting events, suggesting that spatial crime patterns and people’s social posts are similar on event days and more dissimilar on non-event days. The subjectivity in crime is captured through the lenses of fear of crime. This project is an approach to amalgamate the knowledge about safety features already studied in the urban environment. The primary goal of this work is in using a fusion methodology for integrating a systematic video data acquisition, geographical storytelling, and human physiological measurements to build upon the analysis of the urban environment through a GIS-based platform. The three main objectives of this project are: (1) to test the compatibility of data acquisition through mixed technologies; (2) to extract safety information from the data acquired using mixed methods and to implement it in a GIS-based model; (3) to compare official crime data reported to the police, urban blight indicators and people’s perceived safety, extracted from the mixed-method approach.

Life Cycle Stages, Daily Contacts, and Activity-Travel Time Allocation for the Benefit of Self and Others

 

Konstadinos G. Goulias

Department of Geography
University of California, Santa Barbara

11:30 a.m. (PST) Tuesday, April 28, 2020

Zoom : https://ucsb.zoom.us/j/96140245863

Abstract:

In this research, we study the correlation between life cycle stages and time allocation for the benefit of self and others. Life cycle stages are defined based on age, employment, family status, and disabilities. Time allocation is classified based on the people with whom each respondent came in contact and for whom he or she performed activities and travel. Based on a two-day time use diary, daily time allocation is classified in social fields that we define as family, friends, schoolmates, co-workers, clubmates, and others. We also include time for sleeping and activities and travel for one’s self. The data analysis creates a taxonomy using cluster analysis of time-of-day activity sequences, complexity of time schedules, and uncovers its correlation with life cycle stages.

Qualitative Spatial Reasoning Using Answer Set Programming

 

George Baryannis

Department of Computer Science
University of Huddersfield, UK

11:30 a.m. Tuesday, April 21, 2020 | Zoom meeting room:

https://ucsb.zoom.us/j/96140245863

Abstract:

Spatial (and temporal) information is often expressed using qualitative terms such as natural language expressions instead of coordinates; reasoning over such terms has several practical applications, such as naval traffic monitoring, warehouse process optimization and robot manipulation. Well over 40 qualitative calculi have been proposed so far, including Allen’s interval algebra and the Region Connection Calculus. Reasoning with such calculi has been the focus of extensive research within the wider AI community, with a number of specialized reasoning tools developed. One barrier to the wide adoption of these tools is that only qualitative reasoning is supported natively, when real-world problems most often require a combination of qualitative and other forms of reasoning.

I will discuss research to overcome this barrier (conducted at the University of Huddersfield, UK and the University of Calabria, Italy),  focusing on using Answer Set Programming (ASP) as a unified formalism to tackle problems that require qualitative reasoning in addition to non-qualitative reasoning. ASP is a logic-based knowledge representation and reasoning approach that includes a rich but simple modeling language and is capable of handling search problems of high complexity. Research is motivated by two case studies: reasoning about the  relations among large numbers of trajectories and determining optimal coverage of telecommunication antennas.

Spread of a virulent amphibian pathogen across the Sierra Nevada

Dr. Roland Knapp

 

Abstract: The global emergence of the amphibian chytrid fungus (Batrachochytrium
dendrobatidis: “Bd”) has caused the extinction of at least 90 frog species and the decline of
hundreds more. This impact has been called the most spectacular loss of vertebrate
biodiversity due to disease in recorded history. Bd is believed to have originated in Asia, but is
now distributed worldwide due to global commerce. In California’s Sierra Nevada mountains,
Bd emerged in the 1960s and subsequently spread across the range, causing precipitous
declines of the once-common mountain yellow-legged frog and its eventual listing under the
U.S. Endangered Species Act. Describing this spread, including identifying factors associated
with its arrival in frog populations, would allow better prediction of future spread and aid in the
identification of possible vectors. In this presentation, I will provide details on the patterns of
Bd spread in the Sierra Nevada and solicit input on how these data could best be analyzed.

Bio:
Roland Knapp is a research biologist at the University of California Sierra Nevada
Aquatic Research Laboratory. His research interests include the population and conservation
biology of endangered mountain yellow-legged frogs in California’s Sierra Nevada mountains,
and the community ecology of montane lake ecosystems. The landscape-scale surveys of
aquatic habitats in the southern Sierra Nevada (7,000+ lakes and ponds) that he led form the
basis for ongoing amphibian and lake recovery efforts in Sequoia, Kings Canyon, and
Yosemite National Parks, and beyond. His current research focuses on the recovery of
mountain yellow-legged frogs in the presence of the recently-emerged amphibian chytrid
fungus (Batrachochytrium dendrobatidis).

Inferring Network Structure and Flows using Partial Observations

Ambuj Singh

University of California Santa Barbara

12:00 p.m. Tuesday, January 21, 2020 | 3512 Phelps Hall (map)

Network

Abstract:

Predicting network structure and flows on edges is a precondition to effective planning and disaster response in critical infrastructure networks. I will summarize some ideas inspired by network science, physical modeling, and machine learning to determine this information from incomplete observations. Using both physical domain-specific and data-driven approaches, these algorithms address diverse problems including: the reconstruction of network topology and parameters, the estimation of network flows, the optimal selection and scheduling of multiple types of sensors, and the modeling of interdependencies in multilayer networks. The overall goal is to develop a rigorous theory for solving the inverse problem of edge and flow determination from observations of critical infrastructure networks.
