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.

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.

The Geography of Forest Hydraulic Trait Compositions: Observed Patterns, underlying Mechanisms, and Future Implications

 

 

Anna Trugman

University of California Santa Barbara

12:00 p.m. Tuesday, March 17, 2020 | 3512 Phelps Hall (map)

 

ABSTRACT:

Tree hydraulic traits determine plant water use and tree vulnerability to drought stress, thereby affecting forest productivity and the movement of water between the land surface and the atmosphere. Here, I leverage an extensive trait database and a long-term continental forest plot network to map changes in community trait distributions and quantify “trait velocities” (the rate of change in community-weighted traits) for different regions and different forest types across the U.S. from 2000 to the present. I find evidence for shifts towards communities with more drought tolerant traits driven by tree mortality. I then review my ongoing work looking at the extent to which community trait compositional changes may buffer forest productivity and water fluxes in the near term from the effects of climate change.

Bridging Space and Place in Geographic Information Systems

Emmanuel Papadakis

University of California Santa Barbara

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

Abstract:

People refer, describe and interact with places; geographic information systems (GIS), however, are designed to visualize, process and analyze spaces. Both place and space are used to describe the geographic world, but each provides a different perspective. Place is an informal view framed by symbols, concepts and experience, whereas space is confined to the rigid digital world that adheres to mathematical formulas, data models and processes. Since digital systems have become a vital part of our lives, it is crucial to enable them to visualize, analyze and process the world as humans do. In this presentation, I will tackle a long-lasting question on whether spatial representation standards infused with semantics can create an adequate reflection of the geographical world as it is projected in the human mind. Using the concept of functions, I show how important aspects of place can be formalized and be integrated into GIS. Through examples on place-based search, I depict how a system can combine the processing and visualizing capabilities of machines with the sophisticated concept of place, contributing to the overall idea of a place-based GIS. Finally, I give some insights on further research that aims to incorporate emotions and similar concepts in the aforementioned formalization. Also, I propose the idea of an Algebra of Patterns, which focuses on innovative ways of conducting place synthesis, search, and discovery.

Multi-Scale Modeling and Analysis of Movement

Somayeh Dodge

University of California Santa Barbara

12:00 p.m. Tuesday, January 14, 2020 | 3512 Phelps Hall (map)

Abstract:

Movement is a complex multidimensional process that operates in a space-time-context continuum across multiple scales. Regardless of the context or entity type, movement happens through a series of embedded patterns at different granularities. Hence, the study of movement requires careful consideration and integration of all three forms of granularity (as in Kuhn (2012)): spatial (micro-steps to macro flows), temporal (high-frequency short-term events to low-frequency long-term processes), and thematic (individual movement to collective dynamics). This presentation reviews my ongoing work on synthesizing a multiscale model of movement through mining and integration of movement patterns at different granularities. Using movement ecology as an application, I show how multiscale analysis of trajectories are applied to identify patterns of movement at different frequencies and how these patterns can be combined in a multiscale model of movement to reconstruct trajectories.

Limes – Who? What? When? Where? Why? A ThinkSpatial Recap

The Spatial Center was glad to invite Grant McKenzie, one of Geography’s own graduates, back from the chill of Montreal for a visit and talk on March 5. Formerly from the STKO lab, Grant is interested in how geographic information has a role to play in the study of the the intersection of information technology and society and what we can understand about human behavior.

At the Center, he presented some early exploration he and his group were doing on scooters as a form of public transportation. Here, he asked the audience if anyone frequently used Lime to get around (just one?!):

Engaging participants across disciplines -- Public Scooters
Engaging participants across disciplines — Public Scooters

This analysis led to a discussion about Lime’s function for users as a replacement for or adjacent to bike sharing and other form of shared economy transport means.

Introducing the Subject - Grant McKenzie
Introducing the Subject – Grant McKenzie

One of the takeaways? It looks like (in DC) bikes are used for commute (such as to and from work), whereas scooters are used for quick, short trips (average duration of just 5 minutes!).

Spatial Thinking as a Heuristic:

Shaping Learning about Teaching

Linda Adler-Kassner

University of California Santa Barbara

Director, Center for Innovative Teaching, Research, and Learning
Associate Dean, Undergraduate Education
University of California, Santa Barbara

12:00 p.m. Tuesday, March 12, 2019 | 3512 Phelps Hall (map)

Abstract:

Teaching is a complex activity, especially for faculty members who are experts in their disciplines. Faculty members need to take into account a number of complex concepts associated with contexts for teaching and learning, disciplinary identities, representational practices, and students and their identities in order to make learning accessible. At the same time, the ways in which these ideas need to be considered are themselves areas of learning. Adler-Kassner will discuss how spatial thinking can serve as a visual metaphor for facilitating faculty members’ thinking about learning. As a faculty member whose research is bound up with contributing to a research-based teaching culture in our research university, she will describe the evolution of a spatial model intended to facilitate others’ thinking about epistemologically inclusive teaching. Since attendees are “also” teaching, feedback and discussion about the idea of spatial thinking as a heuristic will also be encouraged.

Bio: Linda Adler-Kassner is Professor of Writing Studies; Director of the Center for Innovative Teaching, Research, and Learning; and Associate Dean of Undergraduate Education in the College of Letters and Science. Her research focuses broadly on how literacy is defined, taught, and assessed in disciplinary contexts, and on implications of those definitions for students, for teaching, and for public policy. Adler-Kassner is author, co-author, or co-editor of 11 books and more than 50 articles and book chapters and worked with faculty across the country on issues associated with teaching and learning. She has served as President of the Council of Writing Program Administrators, Chair of the Conference on College Composition and Communication, and board member of the National Council of Teachers of English. The objectives of the ThinkSpatial brown-bag presentations are to exchange ideas about spatial perspectives in research and teaching, to broaden communication and cooperation across disciplines among faculty and graduate students, and to encourage the sharing of tools and concepts.
