Evaluation of the US Forest Service - Forest Stewardship Program and Spatial Analysis Project in Illinois

Martinek, Michael Anthony 01 December 2010 (has links)
In 1978, the Federal government passed the Forestry Assistance Act which provides guidelines for states to support management on non-industrial private lands through the Forest Stewardship Program (FSP). In 1983, Illinois passed the Illinois Forestry Development Act which outlines the specific requirements for non-industrial private landowners residing in Illinois to take advantage of the FSP. Since the inception of the program, there has been little analysis to determine the quality of land enrolled in the FSP. Launched in 2004, the Spatial Analysis Project is a program sponsored by the US Forest Service to determine the type of land enrolled within FSP. Within each state, the SAP used an aggregate analysis based upon multiple criteria to divide all land available for the FSP into three categories - low, medium, and high stewardship potential. The objective of this project was twofold, first to determine if Illinois is effectively enrolling lands in the high stewardship potential category. Secondly, because timber production must be the primary goal of a FSP plan in Illinois, this study analyzed whether lands classified as high stewardship potential were also high in forest productivity. Results indicate that while Illinois is effectively enrolling high stewardship potential lands, these lands are not necessarily highly productive. This information could be used to give preference for cost-share assistance to those lands that are classified as highly productive, particularly in times when funding is limited, rather than on a first come, first served basis.

A preocupação com o meio ambiente é uma das maneiras mais eficazes de conter a reprodução do mosquito Aedes aegypti que, segundo Organização Mundial da Saúde, infecta cerca de 100 milhões de pessoas por ano. Esta pesquisa teve como objetivo principal analisar a distribuição espacial dos casos de dengue confirmados autóctones e importados, bem como dos recipientes de larvas do mosquito no município de Itu, São Paulo no período de 2005 a 2014. Para o desenvolvimento do trabalho foi realizada uma pesquisa junto à Vigilância Epidemiológico da área de estudo para obtenção dos dados, acompanhada de pesquisa bibliográfica e trabalho de campo. Os dados foram tratados por meio de técnicas de geoprocessamento e análise estatística exploratória. Os resultados obtidos demonstraram uma crescente alta de casos e de incidência ao longo dos anos estudados da faixa de 10 anos, sendo que os casos autóctones se sobrepõe em termos de ocorrência aos importados em 88 %. Além disso, foi possível verificar uma distribuição espacial com maiores ocorrências nas regiões centrais da área urbana do município estudado, apresentando as maiores concentrações nos anos de 2007, 2009, 20011 e 2013 do total analisado, com distribuição tendendo para a direção sudeste-noroeste da área de estudo. Diante destas constatações é possível afirmar que a alta urbanização afeta diretamente o ambiente propiciando o aumento ponderal de casos confirmados de dengue na área de estudo, sendo que a elaboração de informações relacionadas a distribuição da população e locais de ocorrência de larvas e consequentemente dos mosquitos poderão contribuir de forma mais efetiva com o entendimento da epidemiologia da dengue na área de estudo. / The control of the vectors of the mosquito Aedes aegypti presents as one of the main problems of public health in the world acted by two important slopes as the care with the environment and for the investment in science. The concern with the environment is one in the most effective ways of containing the reproduction of the mosquito Aedes aegypti that, second World Organization of the Health, infects about 100 million people a year. This research had as main objective to analyze the space distribution of the cases of primness confirmed autochthonous and mattered, as well as of the containers of larvas of the mosquito in the municipal district of Itu, São Paulo in the period of 2005 the 2014. For the development of the work a research was accomplished the Surveillance Epidemic of the study area close to for obtaining of the data, accompanied of bibliographical research and field work. The data were treated through geoprocessamento techniques and exploratory statistical analysis. The obtained results demonstrated a crescent high of cases and of incidence along the studied years of the 10 year-old strip, and the autochthonous cases are put upon in occurrence terms to the mattered in 88%. Besides, it was possible to verify a space distribution with larger occurrences in the central areas of the urban area of the studied municipal district, presenting the largest concentrations in the years of 2007, 2009, 20011 and 2013 of the analyzed total, with distribution tending for the southeast-northwest direction of the study area. Due to these verifications it is possible to affirm that the high urbanization affects the atmosphere directly propitiating the increase ponderal of confirmed cases of primness in the study area, and the elaboration of related information the distribution of the population and places of occurrence of larvas and consequently of the mosquitos they can contribute in a more effective way with the understanding of the epidemiology of the primness in the study area.

Distribuição espacial do número de internações por infarto agudo do miocárdio e doença isquêmica do coração no Vale do Paraíba paulista, 1999-2000 / 2004-2005 /

Soares, Paula Adriana. January 2008 (has links)
Orientador: Luiz Fernando da Costa Nascimento / Banca: Walnei Fernandes Barbosa / Banca: Getúlio Teixeira Batista / Resumo: A análise espacial é uma importante ferramenta para estudo das doenças em grupos populacionais. O objetivo deste estudo é analisar a distribuição espacial do número de internações por infarto agudo do miocárdio e doença isquêmica do coração no Vale do Paraíba Paulista, Brasil. Foram utilizadas as estatísticas de internação do Sistema Único de Saúde, no portal DATASUS, segundo sexo e faixa etária acima de 30 anos, em dois períodos distintos: 1999-2000 e 2004-2005. As estatísticas e a distribuição espacial foram realizadas por meio do programa TERRAVIEW. Para minimizar as flutuações aleatórias das taxas, empregou-se o método Bayesano empírico. A unidade de análise do padrão espacial foi constituída pelos 35 municípios que compõem o Vale do Paraíba Paulista. Para análise da autocorrelação espacial foram utilizados: Moran global, Moran local, diagrama de espalhamento de Moran. As distribuições espaciais para infarto agudo do miocárdio e doença isquêmica do coração no Vale do Paraíba Paulista evidenciaram autocorrelação espacial, estatisticamente significativa, para os dois períodos. Os resultados para os dois períodos apontam a existência de um aglomerado central, em que se concentram as maiores taxas, constituídos pelos municípios: Guaratinguetá, Campos do Jordão, São Bento do Sapucaí e Santo Antônio do Pinhal. Os dos fatores individuais e contextuais possivelmente são indicativos da necessidade de incorporação de novos parâmetros, proporcionando novos meios para identificação de áreas problemáticas. / Abstract: Spatial analysis is an important tool for the study of diseases in population groups. The objective of this study is to analyze the spatial distribution of the number of hospitalizations for acute heart attack of myocardium and ischemic disease of the heart in the Vale do Paraiba Paulista, Brazil. Were used statistics for hospitalization of the Unified Health System, the portal DATASUS, according to sex and age above 30 years, in two distinct periods: 1999-2000 and 2004-2005. The statistics and spatial distribution were performed through the program TERRAVIEW. To minimize the random fluctuations of the rates is the method employed Bayesano empirical. The unit of analysis of the spatial pattern was formed by 35 municipalities that make up the Vale do Paraiba Paulista. For analysis of the spatial autocorrelation were used: Moran global, local Moran, of Moran diagram of scattering. The spatial distributions for acute heart attack of myocardium and ischemic disease of the heart in the Vale do Paraiba Paulista showed spatial autocorrelation, statistically significant for the two periods. The results for both periods indicate the existence of a central cluster, which concentrated the higher rates, made by municipalities: Guaratinguetá, Campos do Jordao, São Bento do Sapucaí, Santo Antonio do Pinhal. The factors of the individual and contextual possibly are indicative of the need to incorporate new parameters, providing new means for identifying problem areas. / Mestre

Comparing statistical inference and spatial analysis in geomorphology : a case study of Rietvlei Nature Reserve, Gauteng

Van der Merwe, Barend Jacobus January 2013 (has links)
This dissertation presents the findings of a study that was undertaken in order to investigate the differences in conclusions drawn based on the method of analysis. Specifically, the conclusions drawn using inferential statistics was compared to the conclusions drawn using spatial analysis. The peatlands of Rietvlei Nature Reserve was selected as the landscape unit for this study and two soil attributes, namely soil pH and soil carbon, was investigated. Prior to data analysis outliers were identified and removed using the interquartile method. The findings suggest that there are indeed large differences between the conclusions drawn using the various approaches with the spatial analysis revealing larger differences between the two study sites. It is argued that the limitations imposed by the nature of geographic data need to be taken into consideration when any statistical or spatial analysis is carried out. / Dissertation (MSc)--University of Pretoria, 2013. / gm2014 / Geography, Geoinformatics and Meteorology / unrestricted

A Geospatial Analysis: Impacts of Hurricane Matthew, St. Catherines Island, Georgia

Dobson, Steven 08 August 2017 (has links)
The purposes of this study were to evaluate the shoreline dynamics and environmental change of St. Catherines Island shoreline through the application of an updated shoreline model (1859-2017). Efforts were completed to document and quantify the impacts to the nearshore environments of the island from Hurricane Matthew (07-08 October 2016). This was accomplished through the measurement of Net Shoreline Movement (NSM) that was performed along the shoreface at 200-meter spacings by using aerial imagery and ground-collected GPS data. The Hurricane Matthew NSM data along with the short-term shoreline rates were used to calculate the years of change along the shoreline in response to the storm, indicating that the storm represented an average of 3.7 years of average erosion. A spatial analysis of impacts conducted along the shoreline revealed major habitat losses within the study area of 66.5 acres and the limited accretion of 3.7 acres.

Spatial Analysis and Determinants of Asthma Health and Health Services Use Outcomes in Ontario

Ouedraogo, Alexandra January 2016 (has links)
This thesis explores the spatial patterns and determinants of asthma prevalence and health services use (ICD-10 codes J45, J46) for the total population (all ages and both sexes combined) of the province of Ontario, Canada, between 2003 and 2013. Asthma is characterized by high health services use and reduced quality of life for asthma sufferers, representing a considerable burden on individuals, society and the health care system. While recent evidence suggests increasing asthma prevalence in Ontario, little research has been done to understand the identified spatial variability of this disease. Using population-based, ecological-level data and refined spatial analysis techniques, this research aims to explore the spatial patterns of asthma prevalence and health services use in Ontario, and examine the contribution of potential risk factors including air pollution, pollen, deprivation, physician supply and rurality. Results indicated considerable spatial variability in asthma outcomes across Ontario. Similar patterns were found between asthma prevalence and physician visits; clusters of high rates were generally found in southern urban/suburban areas, and clusters of low rates were mainly identified in most northern and southern rural areas. Conversely, clusters of high rates of ED visits and hospitalizations were found in most northern and southern rural areas, whereas clusters of low rates were found in south urban/suburban areas near Toronto. Findings from the spatial regression analysis indicated that while rurality was negatively associated with asthma prevalence and physician visits, it was positively associated with ED visits. Moreover, positive associations were also found between material deprivation and asthma prevalence and ED visits, and between NO2 and asthma physician visits. This research contributes to a better understanding of area characteristics that influence asthma disparities, which can help develop better, locally relevant public health strategies aimed at reducing the burden of asthma in Ontario. Further, it demonstrates the importance of using a population-based framework and spatial analysis approaches, which take into account the spatial nature of asthma morbidity and their determinants.

Spatial Analysis of Hiv/aids Survival in Dallas and Harris Counties, Texas

Heald, Stephanie 05 1900 (has links)
More Texans are living with HIV infection than ever before. in fact, there has been a 6% increase annually, since 2002. This trend is not a result of increased HIV/AIDS incidence, but rather improving life expectancy of those living with HIV. Due to significant advances in HIV/AIDS testing, prevention, and treatment, individuals with HIV are living longer than ever before. However, throughout the state, the life expectancy of a person infected with HIV/AIDS varies spatially. This study investigates and attempts to explain the spatial distribution of HIV/AIDS survival rates by examining neighborhood socioeconomic characteristics. the results suggest that, contrary to expectation, the lowest survival rates occur, not in extreme poverty areas, but rather in moderate SES areas. Too rich to qualify for free treatments, but not rich enough to afford purchasing such treatments, the middle income living with HIV infection are caught between the cracks. the results provide important input for targeting public health interventions to improve HIV/AIDS survival.

Usefulness of GIS in Mass Transit: An Analysis of the ridership characteristics of Greater London and D.C. Metropolitan Region

Chatterjee, Arpita Shankar 29 July 2004 (has links)
The Geographic Information Systems (GIS) programs offered a multitude of useful analysis tools for a variety of purposes in the transit industry. One of the significant contributions that GIS offers is the ability to manage and spatially display transit data and then overlay these layers to perform analyses. This paper focuses on how GIS can be used in mass transit planning to understand and analyze basic ridership characteristics. Mass transit is gaining a lot importance in recent years because of the growing concern over the impact of automobiles on our environment and specifically on the quality of life in the urban areas. This paper attempted to use GIS to investigate the ridership characteristics of the transit system in Greater London and the D.C. Metropolitan region.<p> In this paper, ridership characteristics essentially refer to the mode of transportation of the working population and their socio-economic characteristics. The ridership characteristics help us understand generalized travel patterns and the preferred mode of transportation; whether the people prefer public transportation to private transportation. My analysis supported the concept that there is often a nexus between the choice in the mode of transportation, and the socioeconomic conditions of the working population. / Master of Urban and Regional Planning
