Segmenting Human Trajectory Data By Movement States While Addressing Signal Loss And Signal Noise, Sungsoon Hwang, Cynthia Vandemark, Navdeep Dhatt, Sai Yalla, Ryan Crews Dec 2017

Segmenting Human Trajectory Data By Movement States While Addressing Signal Loss And Signal Noise, Sungsoon Hwang, Cynthia Vandemark, Navdeep Dhatt, Sai Yalla, Ryan Crews

Sungsoon Hwang

This paper considers the problem of partitioning an individual GPS
trajectory data into homogeneous, meaningful segments such as
stops and trips. Signal loss and signal noise are highly prevalent in
human trajectory data, and it is challenging to deal with uncertainties
in segmentation algorithms. We propose a new trajectory
segmentation algorithm that detects stop segments in a noiserobust
manner from GPS data with time gaps. The algorithm consists
of three steps that impute time gaps, split data into base
segments and estimate states over a base segment. The statedependent
path interpolation was proposed as a framework for
gap imputation to …

Food Justice Youth Development: Using Photovoice To Study Urban School Food Systems, Krista Harper, Catherine Sands, Diego Angarita, Molly Totman, Monica Maitin, Jonell Sostre Rosado, Jazmin Colon, Nick Alger

Catherine Sands

How do youth learn through participation in efforts to study and change the school food system? Through our participatory youth action research (YPAR) project, we move beyond the "youth as consumer" frame to a food justice youth development approach. We track how a group of youth learned about food and the public policy process through their efforts to transform their own school food systems by conducting a participatory evaluation of farm-to-school efforts in collaboration with university and community partners. We used the Photovoice research method, placing cameras in the hands of young people so that they themselves could document and …

Creating Healthy Community In The Postindustrial City, Brian A. Hoey Dec 2014

Creating Healthy Community In The Postindustrial City, Brian A. Hoey

Brian A. Hoey, Ph.D.

This chapter explores how community might be reimagined for the benefit of public health as well as to promote incipient social or economic agendas born of progressive citizen action aimed at what is commonly characterized as development or, perhaps, even more broadly as “growth.” Can a city like Huntington, West Virginia, emerge as a positive example of what we might term postindustrial urban regeneration and perhaps even community healing? Can this happen specifically through a grassroots movement now finding local governmental support in a collective attempt to transform this place from one defined primarily by the productive capacity of factories …


Capitalizing On Distinctiveness: Creating Wv For A New Economy, Brian A. Hoey Dec 2014

Capitalizing On Distinctiveness: Creating Wv For A New Economy, Brian A. Hoey

Brian A. Hoey, Ph.D.

This article explores use of images and ideas of place to promote particular social and economic agendas within the regional context of Appalachia. Despite prevailing imageries of backwardness and isolation that adhere to the region, as well as recent history of often-bleak economic conditions, communities such as Huntington, West Virginia, are ideal places to observe inventive forms of community-building, place-making, and place-marketing that borrow from emerging cultural and economic models and stand in sharp contrast to a once dominant paradigm that encouraged capital investment by relying simply on tax breaks and the provision of cheap land and labor to attract …

Community-Level Characteristics Associated With Variations In Rates Of Homelessness Among Families And Single Adults, Jamison D. Fargo, Ellen A. Munley, Thomas H. Byrne, Ann Elizabeth Montgomery, Dennis P. Culhane

Dennis P. Culhane

Objectives. We modeled rates of family and single-adult homelessness in the United States in metropolitan and nonmetropolitan regions and as a function of community-level demographic, behavioral, health, economic, and safety net characteristics.
Methods. We entered community-level characteristics and US Department of Housing and Urban Development point-in-time counts for a single night in January 2009 into separate mixed-effects statistical analyses that modeled homelessness rates for 4 subpopulations: families and single adults inmetropolitan and nonmetropolitan regions.
Results. Community-level factors accounted for 25% to 50% of the variance in homelessness rates across models. In metropolitan regions, alcohol consumption, social support, and several economic …


Why Are There Delays In Seeking Treatment For Childhood Diarrhoea In India?, Nisha Malhotra May 2013

Why Are There Delays In Seeking Treatment For Childhood Diarrhoea In India?, Nisha Malhotra

Nisha Malhotra

Abstract Aim To examine the barriers and facilitating factors for seeking treatment for childhood diarrhoea and to determine the main causes for delay in seeking treatment.

Methods Data from Indian Demographic and Health survey 2005–06 (NFHS-III) was used. Mothers were asked if their children (<5-years) had suffered from diarrhoea during the two weeks preceding the survey. Data were collected on the time of seeking treatment after start of the illness, and days waited to seek treatment after the diarrhoea started. Multivariate logistic regression analysis was performed to find the determinants of seeking treatment at the health facility and the factors responsible for the “delay” in seeking advice/treatment.

Results Out of a sample of 41,287 children, 3890 (9.4%) reportedly had diarrhoea. Sixty percent of children with diarrhoea were taken to a health facility. Mother's education till higher secondary and above (OR 1.65; 95% CI, 1.08 – 2.54), richest (OR 1.76; 95% CI, 1.24 – 2.48) wealth index, mother's lack of knowledge of oral …

Spatial Analysis Of Preterm Birth Demonstrates Opportunities For Targeted Intervention, A. South, D. Jones, E. Hall, S. Hyo, J. Meinzen-Derr, L. Liu, James Greenberg

David E. Jones

To develop a specific, targeted intervention strategy for reducing preterm birth through use of geo- graphic analysis. We utilized Hamilton County, Ohio vital records and Census data from 2003 to 2006. Spatial scan- ning statistics allowed determination of the prevalence of preterm birth for any geographical point. Attributable risk calculations demonstrated heterogeneity of risk factors within areas of high or low preterm birth prevalence. Three geographically separate areas with high preterm birth proportions ([16%) had differing primary risk factors for preterm birth, including short interpregnancy interval, previous preterm birth, and low prepregnancy weight, despite similarities in demographics and …

Confluence Journal of Environmental Studies (CJES), Kogi State University, Nigeria

The spatial distribution of banks in any geographic entity determines the level of accessibility to its services by the public. This study examined the pattern of banks distribution in Ilorin metropolis. Field survey was employed in determining the number of available commercial banks and their respective distances between each other. The spatial analysis technique such as the nearest neighbour analysis as used ascertain the degree of clustering, density and the average distance taken to access these services. The study revealed that about 96% of the total number of banks are situated in the Central Business District which exhibited a very …


Gay And Lesbian Elders: History, Law, And Identity Politics In The United States, Nancy J. Knauer Dec 2009

Gay And Lesbian Elders: History, Law, And Identity Politics In The United States, Nancy J. Knauer

Nancy J. Knauer

The approximately two million gay and lesbian elders in the United States are an underserved and understudied population. At a time when gay men and lesbians enjoy an unprecedented degree of social acceptance and legal protection, many elders face the daily challenges of aging isolated from family, detached from the larger gay and lesbian community, and ignored by mainstream aging initiatives. Drawing on materials from law, history, and social theory, this book integrates practical proposals for reform with larger issues of sexuality and identity. Beginning with a summary of existing demographic data and offering a historical overview of pre-Stonewall views …


A Photovoice Participatory Evaluation Of A School Gardening Program Through The Eyes Of Fifth Graders, Catherine Sands, Krista Harper, Lee Ellen Reed, Maggie Shar Dec 2008

A Photovoice Participatory Evaluation Of A School Gardening Program Through The Eyes Of Fifth Graders, Catherine Sands, Krista Harper, Lee Ellen Reed, Maggie Shar

Catherine Sands

In the springtime, fifth grade students at the Williamsburg Elementary School in rural Western Massachusetts ask to snack on sorrel and chives from the school garden, between planting potatoes and building a shade structure for their outdoor classroom. They are members of the first cohort of the curriculum-integrated program initiated by Fertile Ground, a grassroots organization in western Massachusetts. The children’s delight in the fresh greens they have grown marks a national phenomenon: the farm-to-school movement. With limited resources, parents, teachers, students, administrators, and community activists are developing inroads to better school food and food education, by constructing school teaching …


Mapping As A Knowledge Translation Tool For Ontario Early Years Centres: Views From Data Analysts And Managers, Anita Kothari, S. Michelle Driedger, Julia Bickford, Jason Morrison, Michael Sawada, Ian D. Graham, Eric Crighton Jan 2008

Mapping As A Knowledge Translation Tool For Ontario Early Years Centres: Views From Data Analysts And Managers, Anita Kothari, S. Michelle Driedger, Julia Bickford, Jason Morrison, Michael Sawada, Ian D. Graham, Eric Crighton

Anita Kothari

Background: Local Ontario Early Years Centres (OEYCs) collect timely and relevant local data, but knowledge translation is needed for the data to be useful. Maps represent an ideal tool to interpret local data. While geographic information system (GIS) technology is available, it is less clear what users require from this technology for evidence-informed program planning. We highlight initial challenges and opportunities encountered in implementing a mapping innovation (software and managerial decision-support) as a knowledge translation strategy.

Methods: Using focus groups, individual interviews and interactive software development events, we taped and transcribed verbatim our interactions with nine OEYCs in Ontario, Canada. …


Correction: Using Participatory Design To Develop (Public) Health Decision Support Systems Through Gis, S. Michelle Driedger, Anita Kothari, Jason Morrison, Michael Sawada, Eric J. Crighton, Ian D. Graham Nov 2007

Correction: Using Participatory Design To Develop (Public) Health Decision Support Systems Through Gis, S. Michelle Driedger, Anita Kothari, Jason Morrison, Michael Sawada, Eric J. Crighton, Ian D. Graham

Anita Kothari

Background: Organizations that collect substantial data for decision-making purposes are often characterized as being 'data rich' but 'information poor'. Maps and mapping tools can be very useful for research transfer in converting locally collected data into information. Challenges involved in incorporating GIS applications into the decision-making process within the non-profit (public) health sector include a lack of financial resources for software acquisition and training for nonspecialists to use such tools. This on-going project has two primary phases. This paper critically reflects on Phase 1: the participatory design (PD) process of developing a collaborative web-based GIS tool.

Methods: A case study …
