Open Source Foundations For Spatial Decision Support Systems, Jochen Albrecht

Publications and Research

Spatial Decision Support Systems (SDSS) were a hot topic in the 1990s, when researchers tried to imbue GIS with additional decision support features. Successful practical developments such as HAZUS or CommunityViz have since been built, based on commercial desktop software and without much heed for theory other than what underlies their process models. Others, like UrbanSim, have been completely overhauled twice but without much external scrutiny. Both the practical and the theoretical foundations of decision support systems have developed considerably over the past 20 years. This article presents an overview of these developments and then looks at what corresponding tools …

Identification Of Experimental And Control Areas For Cctv Effectiveness Assessment—The Issue Of Spatially Aggregated Data, Adam Dabrowski, Piotr Matczak, Andrzej Wójtowicz, Michael Leitner

Faculty Publications

Progress in surveillance technology has led to the development of Closed-Circuit Television (CCTV) systems in cities around the world. Cameras are considered instrumental in crime reduction, yet existing research does not unambiguously answer the question whether installing them affects the number of crimes committed. The quasi-experimental method usually applied to evaluate CCTV systems’ effectiveness faces difficulties with data quantity and quality. Data quantity has a bearing on the number of crimes that can be conclusively inferred using the experimental procedure. Data quality affects the level of crime data aggregation. The lack of the exact location of a crime incident in …

Coupling Between Land–Ocean–Atmosphere And Pronounced Changes In Atmospheric/Meteorological Parameters Associated With The Hudhud Cyclone Of October 2014, Akshansa Chauhan, Rajesh Kumar, Ramesh P. Singh

Mathematics, Physics, and Computer Science Faculty Articles and Research

India is vulnerable to all kinds of natural hazards associated with land, ocean, biosphere, atmosphere, and snow/glaciers. These natural hazards impact large areas and the population living in the affected regions. India is surrounded by ocean on three sides and is vulnerable to cyclonic activities. Every year cyclones hit the east and west coasts of India, affecting the population living along the coasts and infrastructure and inland areas. The extent of the affected inland areas depends on the intensity of the cyclone. On 12 October 2014, a strong cyclone “Hudhud” hit the east coast of India that caused a high …

Land Use And Land Cover Changes, And Environment And Risk Evaluation Of Dujiangyan City (Sw China) Using Remote Sensing And Gis Techniques, Biswajit Nath, Zheng Niu, Ramesh P. Singh

Mathematics, Physics, and Computer Science Faculty Articles and Research

Understanding of the Land Use and Land Cover (LULC) change, its transitions and Landscape risk (LR) evaluation in earthquake-affected areas is important for planning and urban sustainability. In the present study, we have considered Dujiangyan City and its Environs (DCEN), a seismic-prone area close to the 2008 Wenchuan earthquake (8.0 Mw) during 2007–2018. Five different multi-temporal data sets for the years 2007, 2008, 2010, 2015, and 2018 were considered for LULC mapping, followed by the maximum likelihood supervised classification technique. The individual LULC maps were further used in four time periods, i.e., 2007–2018, 2008–2018, 2010–2018, and 2015–2018, to evaluate the …

Analysis Of Land Surface Temperature Over Urban Landcover Types Using Satellite Remote Sensing And Ground-Based Applications, Makini Valentine, Justine Ginchereau

Publications and Research

Urban areas have discrete differences in their land surface temperatures (LST) compared to rural areas. These regions are covered with impermeable materials with less vegetation and moisture. Consequently, this phenomenon causes major thermal intensities of different land surfaces, negatively impact people and environment. The objective of this project is to examine and to compare land surface temperature obtained from in-situ data and satellite-based observations in order to understand the diurnal variation and heat transfer at each surface type. The study utilizes series of hand held thermal infrared cameras and one Unmanned Aerial Vehicle (UAV) infrared camera to find land surface …

Discovery From Failure: Understanding Developing Countries' Battles With Poverty And Culturally Appropriate Answers To Them, Daniel Tennant

Honors Theses

This paper is an examination of a failed research attempt, followed by examination of successful research literature on the subject of the informal economy and poverty. The research is centered on peripheral regions of the world, namely in Sub-Saharan countries such as Senegal. The informal economy continues to grow without thorough understanding or measurement of it creating greater problems in the future. The examination highlights the need for culturally appropriate questions, methodologies, and answers to issues of poverty in developing countries. Western World bias needs to be considered when creating and executing research in developing countries if the results are …

Using Deep Learning To Forecast Spatiotemporal Crime Patterns, Shuzhan Fan

LSU Doctoral Dissertations

The distributional patterns of crime occurrences are closely related to their spatial, temporal, and environmental contexts. It has been a hot topic for researchers and crime analysts to discover such complex relationships in order to forecast crime, both spatially and temporally. Many factors play a role in the occurrences of crimes. Conventional crime forecasting research has primarily relied on historical crime records and socioeconomic data, while ignoring the rich social media and other environmental context data. The large volume of data requires a more appropriate forecasting framework with the ability to take in massive multimodal data and possibly achieve better …

Lone Wolves And Copycats: Assessing Policy And Infrastructure For Flood Hazard And Floodplain Management, Samantha L. Hamlin

Dissertations and Theses

To mitigate flood hazard, which affects millions of people every year, increasing numbers of communities are developing green infrastructure policies to not only mitigate the hazard, but to meet other community policy objectives, as green infrastructure is often cited for the multiple benefits it confers. To support the implementation of policies that help communities meet their policy objectives, however, it is imperative to understand how policy is innovated and adopted. To do so, I applied the internal determinants and regional diffusion models, what I refer to as the lone wolf and copycat models. In policy, a lone wolf innovates a …

Characterizing Temperature Variability States Across Southern South America And Associated Synoptic-Scale Meteorological Patterns, Judah Adam Detzer

Dissertations and Theses

The aim of this thesis is to understand spatiotemporal temperature variability in southern South America by identifying overarching temperature variability states and their associated synoptic-scale meteorological patterns. Further, the temporal frequency of occurrence of those temperature variability states is investigated as is the role of recurrent low-frequency modes of climate variability (El Niño Southern Oscillation and the Southern Annular Mode) on temperature variability. K-means cluster analysis is used to group all months during the period 1980-2015 into four primary categories for summer and winter separately. Monthly maps of temperature anomalies are provided as input to the k-means algorithm and the …

Societal Rebirth: The Importance Of Spirituality, Lauren Rothstein

English Department: Traveling American Modernism (ENG 366, Fall 2018)

This article offers an exploration of what the social consequences are when modernity strips away religious-human relationships to the land. The two texts Black Elk Speaks and Grapes of Wrath both include moments of anonymous forces imposing systematic modernization on society. Particularly, I try to understand the controversial subject of societal rebirths, traditionally defined through employment and steady food source availability. This paper proposes an approach to societal rebirths that emphasizes the importance of spiritual connection to the land through a critical analysis of Bakhtin's theory of Chronotope and Leopold's theory of Land Ethic. On the issue of spiritual connection …

No. 18: Gender Inequality, Poverty And Urban Household Food Security In Cape Town, Mary Caesar, Liam Riley

Hungry Cities Partnership

This discussion paper aims to advance our understanding of the gendered nature of urban household food security and how it is shaped by the relationships between internal household gender dynamics and external social factors of gender- and race-based inequalities. The manifestation of the gender inequalityfood security nexus at the household level is most evident in the different food-related roles and responsibilities adopted by women and men. These differences typically centre on tasks such as growing, purchasing, and preparing food as well as household members who undertake none of these responsibilities. Other gender-based household food security determinants include the gender of …

No. 19: Food Insecurity And Alternative Food Networks In Cities Of The Global South, Gareth Haysom

Hungry Cities Partnership

Using the concept of Alternative Food Networks (AFNs), this discussion paper interrogates these networks and asks how they manifest in the context of food insecurity in cities of the global South. AFNs evident in Northern cities generally present a perspective of the food system that prioritises sustainability and a deep green and often local ethic, embodying aspirations of food system change. In Southern cities, food system engagement is less about engagement for change, but rather to enable food access. Traditional value chain parlance sees a value chain extending from producer to consumer. Drawing on research from food security studies carried …

No. 20: Cross-Platform Food Shopping And Household Food Access In Nanjing, China, Cameron Mccordic, Zhenzhong Si, Taiyang Zhong

Hungry Cities Partnership

Modern urban food systems have evolved into international, multi-scalar and complex networks. The historical evolution of the food system in Nanjing, China, exemplifies this complexity. Nanjing’s food system has undergone successive waves of modernization, bringing changes in consumer food sourcing behaviour along with it. Using household survey data, this investigation assesses the cross-platform food sourcing behaviour of households in Nanjing to untangle some of the complex relationships linking food retailers to consumers in the city. The findings indicate that the surveyed households largely prefer purchasing fresh food from wet markets over prepared food from fast food retailers, restaurants and online …

No. 21: Urban Informal Food Deserts In Windhoek, Namibia, Ndeyapo Nickanor, Lawrence Kazembe, Jonathan Crush

Hungry Cities Partnership

Informal settlements in rapidly-growing African cities are urban and peri-urban spaces with high rates of formal unemployment, poverty, poor health outcomes, limited service provision and chronic food insecurity. Traditional concepts of food deserts developed to describe North American and European cities do not accurately capture the realities of food inaccessibility in Africa’s urban informal food deserts. This paper focuses on a case study of informal settlements in the Namibian capital, Windhoek, to shed further light on the relationship between informality and food deserts in African cities. The data for the paper was collected in 2016 and involved a survey of …

Timing And Formation Of Linear Dunes South Of The Niobrara River Valley, North-Central Nebraska Sand Hills, Ashley K. Larsen

Department of Geography: Dissertations, Theses, and Student Research

The Nebraska Sand Hills is a vast (7,500 square kilometer) area of grass-stabilized sand dunes. Larger dunes in the Nebraska Sand Hills formed primarily during the Late Pleistocene, but many underwent widespread reactivation during the Holocene. Recent Optically Stimulated Luminescence (OSL) dating indicates that the last major phase of reactivation in the Sand Hills was during the Medieval Warm Period, approximately 800 years ago. Nevertheless, many questions about the evolution of the dunes remain unanswered, particularly regarding the formation of linear dunes in portions of the Sand Hills.

This study seeks to understand more about the formation of linear dunes …

Interdependent Infrastructure As Linked Social, Ecological, And Technological Systems (Setss) To Address Lock-In And Enhance Resilience, Samuel A. Markolf, Mikhail Chester, Daniel A. Eisenberg, David Iwaniec, Cliff I. Davidson, Rae Zimmerman, Thaddeus R. Miller, Benjamin Ruddell, Heejun Chang

Geography Faculty Publications and Presentations

Traditional infrastructure adaptation to extreme weather events (and now climate change) has typically been techno-centric and heavily grounded in robustness—the capacity to prevent or minimize disruptions via a risk-based approach that emphasizes control, armoring, and strengthening (e.g., raising the height of levees). However, climate and nonclimate challenges facing infrastructure are not purely technological. Ecological and social systems also warrant consideration to manage issues of overconfidence, inflexibility, interdependence, and resource utilization—among others. As a result, techno-centric adaptation strategies can result in unwanted tradeoffs, unintended consequences, and underaddressed vulnerabilities. Techno-centric strategies that lock-in today’s infrastructure systems to vulnerable future design, management, and …

India’S Unbalanced Urban Growth: An Appraisal Of Trends And Policies, Purva Sharma

Journal of Global Initiatives: Policy, Pedagogy, Perspective

India is considered as a low-level urbanized country. However, the country has experienced a sharp increase in the number of towns and peri-urban areas during the last decade. Despite India’s efforts in planned development, the urban sector has generally remained unplanned and chaotic. It appears that policy interventions have not been able to achieve the desired goals and needs of the urban sector fully. This paper examines the urban policy measures taken since independence and highlights the inadequacies and dilemmas in the urban context of India. This analysis shows how metropolitan areas are spreading outwards due to shifts in population …
