▼ The world-wide earthquake locator is an online mapping application that maps the location and severity of earthquakes which have occurred since 1970`s. The current mapping system the site is using is beginning to look dated and there is an opportunity to update the display using a Google maps mash-up. This would display the data from The U.S geological survey in a modern manner that is consistent with current online mapping trends.
A new visual representation of the USGS information would hopefully allow trends and patterns within the data to be identified. Modernising the map using open source tools such as the Google Ajax API, KML, Perl scripts and Oracle RDBMS should improve the experience for the user and allow them to learn more about the
distribution of larger earthquakes.
Analysis of databases and the data infrastructure will be required in order to ascertain why certain aspects of the site currently do not function.

▼ The Janzen-Connell hypothesis proposes that species-specific enemies promote species coexistence through distance- and density-dependent survival of offspring near conspecific adults. I tested this hypothesis experimentally by transplanting juvenile-sized fragments of two species of brooding corals varying distances from conspecific adults, and observationally by assessing the
spatial distribution of those two species in the field. Small fragments (as proxies for ?6 month old juveniles) of Pocillopora damicornis and Seriatopora hystrix were transplanted 3, 12, 24 and 182 cm upstream and downstream (relative to the prevailing current) of conspecific adults and their survivorship and condition (bitten off, overgrown by algae, or bleached) checked every 1-2 d. I also characterized the
spatial distribution of P. damicornis and S. hystrix within replicated plots on three Fijian reef flats and measured densities of small colonies within 2 m of larger colonies of each species.
Contrary to the Janzen-Connell hypothesis, juvenile-sized transplants exhibited no differences in survivorship as a function of distance from adult P. damicornis or S. hystrix and P. damicornis and S. hystrix were aggregated rather than overdispersed on natural reefs. Survival unaffected by distance from focal colonies as well as certain recruitment processes could generate the observed aggregation. I did observe predation of P. damicornis that was spatially patchy and temporally persistent due to feeding by the territorial triggerfish Balistapus undulatus. This patchy predation did not occur for S. hystrix. Thus, I found no support for the Janzen-Connell hypothesis, but did document hot-spots of species-specific corallivory that could create variable selective regimes on an otherwise more uniform environment, and help maintain the high diversity of corals typical of Indo-Pacific reefs.

▼ Dissertation submitted in partial fulfillment of the requirements for the Degree of Master of Science in Geospatial Technologies
Malaria is a serious health threat in the World, mostly in Africa, where it has been
estimated that 90% of the world's cases occur (WHO, 2008). In Tanzania, close to
93% of the 34.4 million inhabitants are at risk of contracting the disease (PMI, 2005).
According to (Tanzania-Ministry of Health, 2008) the number of morbidity and
mortality among outpatient and inpatient admissions accounts for up to 40 percent.
The aim of this work is to generate useful spatial information to support decision
making concerning malaria control and monitoring in Tanzania.
Several multi-scale maps and graphics showing the most affected areas and
associated indicators which are favorable to mosquito densities through analyzed
data are shown, and suggestions focused on that analysis are given.
The results have shown that the households with bed nets for sleeping, those who are
spraying against malaria and those who are using insecticide mosquito bed nets are at
low risk of contracting malaria disease.

▼ Tuberculosis (TB) is the major cause of health problems in Ethiopia, accounting for more than
thousands of cases and deaths occurring annually. The risks of morbidity and mortality
associated with TB are characterized by
spatial variations across the country. For instance,
Oromia is a region with the largest number of TB cases in Ethiopia (36.80%) and the share of
North Shoa Zone is really quite big (FMOH, 2008).
This study examines the
spatial patterns of TB in North Shoa Zone and identifies those variables
that determine TB clustering. We examine the global and local patterns of TB
distribution by
using individual morbidity data collected from North Shoa Health Bureau in 2008. Global
Moran’s I, Geary’s C and Moran scatter plot are used in determining
distribution of TB. These
were used in identifying areas of hot spot for giving strong care in monitoring and to reduce TB
distribution.
The values for Global Moran’s I shows that the presence of significant TB clustering in North
Shoa Zone. And in six woredas significant TB clustering of similar values were observed by
using cluster map while only in one woreda a significant TB clustering of dissimilar values was
observed. Furthermore, Poisson and negative binomial regression analysis are used in this study.
The findings of these models have shown that all explanatory variables (population density,
number of health centers and prevalence of HIV cases) are significantly associated with TB case
loading.
There is evidence of significant TB clustering in North Shoa Zone. Significant hot spots and cold
spots of TB clusters were identified in six woredas. Poisson and negative binomial regression
analysis show a decrease in TB case loading with increasing number of health centers.
Additionally, it is population density that is highly associated with TB case loading.

▼ In this thesis welfare is examined in a spatial context. A broader definition of welfare is taken so that it includes more than just income. In-kind benefits, indirect costs, life-satisfaction, locational effects are all examined in a spatial context. The impact of these welfare drivers on the spatial distribution is examined with each chapter focusing on a different welfare driver. Differences between areas may be psychical (e.g. climate) or structural (e.g. high education attainment) using a spatial approach can account for some of this variation. An interaction exists between space and the economy which results in agglomeration economies and clustering based on social class. However, there are market failures (e.g. congestion) which can reduce welfare. A broader measure of welfare which includes additional components and not just monetary income acknowledges the spatial heterogeneity that exists across space. A small area examination allows for pockets of deprivation and poverty to be identified. Some of the reasons behind the inequality that exist between and within areas is explored and described. Taking each component in isolation has the power to show the effects of that driver on welfare.
International studies are often limited by a lack of income data at a small area level. This thesis uses the output from a spatial microsimulation model to overcome the lack of income data at a spatial scale. This income data is enhanced through a data fusion process to create and include additional spatially rich welfare data. Spatial methods such as interpolation and network analysis tools are utilised to calculate and create new small area datasets. Mapping tools such as GIS provide the added benefit of displaying results in an effective way. This newly created data can be used to calculate how welfare varies spatially depending upon the definition of welfare used.
The broader definition of welfare adopted is based on conceptual underpinnings that any benefits/costs which increase/decrease individual potential to consume should be included in a measure of welfare. Drivers of welfare examined include intertemporal effects, housing, commuting, labour markets, spatial attributes and exposure to flooding. The sensitivity and impact of each component on individual welfare is examined. By using a spatial approach differences in the impact of each driver across space can be measured. Due to the heterogeneous nature of welfare, some drivers can have positive benefits in some areas but negative in others. By adopting a spatial approach these differences can be identified.
Measuring welfare at a disaggregated spatial scale is required before we attempt to understand why the spatial distribution of welfare looks the way it does. Research such as this is crucial to evaluate and recommend policies that improve welfare and reduce spatial inequalities. Due to their limited nature, identifying areas with greater “need” allows resources to be targeted more efficiently. This thesis makes a number of recommendations in this regard as to why…

Spatial distribution and scaling of avulsions on the King and Ovens River, Victoria, Australia.

▼ Anabranching is a multi-channel river system identified by in-stream vegetated islands or stable alluvial sediment. Avulsions require the abandonment of a river course in favour of a new, more efficient path, generally on the lowest point on the flood plain. Two styles of avulsions exist, progradational and incisional with the former requiring significant flood plain deposition (usually crevasse splays). The Ovens and King River of Northeast Victoria display characteristics of incisional avulsions which need overbank flooding to scour a new channel through surrounding flood plain. The study area of this paper provides a region, unaltered by human interference, to measure all avulsions and their relative distance downstream, an angle which previous literature has not taken up as yet. Results of longitudinal slope, stream discharge, relative flood plain height and sinuosity were based on analysing LiDAR data. Avulsion lengths and distance downstream showed very little correlation (R=2%) and although maximum lengths of avulsions showed greater correlation (R=54%) it still was not strong. Longitudinal slope decreased rapidly from -1.50 m/km to -0.29 m/km after approximately 70 km which correlated to the plateauing for maximum length avulsions. Although shear stress was not measured in this study, its ability to induce knickpoint migration is greater in lower slope regions, providing potential for longer avulsions. Valley-lengths of avulsions also exhibited similar patterns between the Ovens and the King with maximum in lengths at approximately 55 km, which correlated to a plateau in valley-length longitudinal slope. In conclusion, longitudinal slope was the main factor affecting avulsion length. Sinuosity of the Ovens River increased (1.34 to 1.65) whilst avulsion sinuosity decreased suggesting the current channel may avulse to new courses, or existing paleo-channels. The presence of paleo-channels on the wide expanse of flood plain of the lower regions, have a high tendency to attract flow into old conduits instead of scouring new channels for avulsions. Therefore, likelihood is high of reoccupation for avulsions along the Ovens River approximately from Wangaratta preventing the creation of long, whole-system avulsions. Finally, scale invariance of this study can be applied to expectations of avulsion lengths in other anabranching systems which must be considered for town-planning and risk-management. Therefore, providing the tools for predicting avulsions are necessary for future systems.

▼ Latest fisheries directives propose adopting an ecosystem approach to manage fisheries \citep{FAO-EAFM}. Such an approach aims to protect important ecosystems based on the principle that healthy ecosystems produce more and thus enhance sustainability. Unfortunately, quantifying the importance of an ecosystem is a difficult task to do due the immense number of interactions involved in marine systems.
This PhD dissertation relies on the fact that good fisheries
distribution maps could play a very important role as they allow a visual and intuitive assessment of different marine areas. Unfortunately, the limited amount of data available and the inherent difficulties of modelling fishery data has resulted in relatively low quality maps in the near past (see \citep{atlas} and \url{http://www.ices.dk/marine-data/maps/Pages/ICES-FishMap.aspx)}. As a result, the
spatial fisheries management framework requires competent statistical approaches to quantify the importance of different marine areas with an appropriate measure of uncertainty associated to the estimates.
The aim of this PhD is to provide competent
spatial and spatio-temporal modelling approaches that allow us characterise different fishery processes that are relevant for their sustainable management.

▼ With Canada's increasing population, natural disasters such as flooding events will have
an increasing impact on human populations. The severity of these events requires that decision
makers have a clear understanding of the flood risks that communities face in order to plan for
and mitigate flood risks. One key component to understanding flood risk is flood exposure, an
element of which is the presence of structures (e.g., residences, businesses, and other buildings)
in an area that could be damaged by flooding. Presently, several resources exist at both the
national and global level that can be used to estimate the spatial distribution of structures. These
resources are typically generated at global scales and do not account for regional or local data or
processes that could enhance the accuracy and precision of exposure estimation in sparsely
populated areas. The present study investigates the feasibility of creating a region-specific
dwelling distribution model that helps improve estimation of residential structures in rural areas.
Herein, we describe a rural dwelling distribution model for the province of Alberta that can be
used to assist in the estimation of structural exposure to flood risk. The model is based on a
random forest classification algorithm and several publicly available datasets associated with
dwelling and population density. The model was validated using visually referenced data
collected from earth imagery. The resulting dwelling layer was then evaluated in its ability to
spatially disaggregate census dwelling counts, as well as predict dwelling exposure in several
scenarios. This method appears to be a useful alternative to globally scaled models, or using the
census alone, particularly for rural areas of Canada.

▼ Vultures and other animal scavengers have the ability to feed on human remains, which can lead to rapid tissue loss as well as movement of body parts over time. This can lead to misinterpretations of the scene and incomplete recovery of evidence. What is not known, however, is how clothing may affect how vultures feed on human remains and in turn how that may affect the
spatial distribution of the remains. This thesis seeks to explore the effects of clothing on vulture scavenging and
spatial distribution of human remains in Central Texas. Five donated human subjects were dressed in a white t-shirt, blue jeans, socks, and tennis shoes prior to placement at the Forensic Anthropology Research Facility (FARF) at Texas State University. Upon placement, traditional baseline measurements were made to document the placement area and compare to final positions. A drone flew over to capture aerial photographs. During the data collection period for each individual, visual observations, notes, digital photography, and game cameras were used to monitor the subjects. Once the observation period was over for each individual, baseline measurements were taken again in order to document where the scavenged remains were dispersed. The study period refers to the observation time from placement until final data collection. All data for clothed individuals was compared to subjects from past vulture studies using unclothed human subjects. Statistical differences in average feeding times were analyzed using a Welch’s t-test. All baseline measurements were plotted on scatter plots with different colored polygons drawn around each scatter (placement and final) for each clothed individual. GPS data from the unclothed subjects were exported into Google Earth Pro, where polygons were also drawn around each scatter for each unclothed individual. Area was calculated for these polygons within Google Earth. In order to assess postmortem interval (PMI) estimations, weather data was collected and known accumulated degree days (ADD) was calculated for each individual. Total Body Score (TBS) was then assessed for each individual using the Megyesi et al. (2005) method. Estimated ADD was also calculated for each individual using this method. Inaccuracy and bias were then determined for each individual in order to compare known and estimated ADD. Spearman’s rank test and t-test further provided information regarding the utility of this method. Results of this study were presented in terms of feeding pattern/duration,
spatial distribution, and ADD/PMI estimations. The differences in feeding pattern and duration between clothed and unclothed remains were determined to be statistically non- significant. Further, the differences in
spatial distribution between clothed and unclothed remains were also determined to be non-significant. Though there were no statistically significant differences in these areas of the study, some useful information could be extracted from the results. Comparisons of known ADD to estimated ADD calculated via the Megyesi et al. (2005)…

▼ Since the initialization of economic reforms in 1978, China has undergone significant
urbanization and modernization at an increasingly rapid pace, with the national urbanization rate increasing from 17.9% in 1978 to 57.4% in 2016. An increasingly significant portion of China’s population is integrating itself into thriving urbanized areas. Though amounting to only 8.5% of the nation’s total population (1.5 billion), China’s ethnic minority population remains considerable in number. In the future, by adopting the National New-Type Urbanization Plan in 2014, China’s urbanization is expected to evolve into a more human-oriented process, as the plan ambitiously
aims to increase the urban population by another 200 million, most of which will consist of Chinese ethnic minorities. It is hoped that this increase will boost the urbanization rate among Chinese ethnic minorities. The gaps within existing literature and the practicality of improving the inclusivity of the urban minority population in the urbanization process legitimize the development of a comprehensive and retrospective study of the evolution of spatial-temporal dynamics of the distribution of Chinese ethnic groups with a Chinese urbanization perspective on a national scale. Based on national census data from 1990, 2000, and 2010, this study adopts the Standard Deviational Ellipse as a distributional trend measurement of minorities in urban China and determines four major new features of the distribution of the Chinese ethnic minorities over the last twenty-years in China’s urbanization context. First, a three-stage peripheral-to-core transition pattern was observed. Second, it is observed that there is an escalating decline of the urban minority population in the central region of China, particularly since 2000. Third, national-level city agglomerations located in the eastern region of China have begun to play leading roles in minority urbanization, particularly those located in the Yangtze and Pearl River Delta. Fourth, in both China’s west region and its autonomous areas, as continuous beneficiaries of supportive policies, metropolises, such as provincial capitals, have been shaped into important regional minority population concentrations. This study also allows for a better insight of Chinese urbanization processes and their inter/intra-relating mechanisms in ethnic minority areas. Finally, this study’s findings provide insightful and detailed information for scholars, policy and, ultimately, decisionmakers, to improve the process for sustainable and inclusive urbanization in China.

▼ The objectives of our study were to investigate the
spatial ecology of Ae. albopictus, to evaluate some potential management methods, and to characterize its host feeding patterns in a suburban landscape. We monitored Ae. albopictus oviposition activity with oviposition traps at fixed stations, conducted container surveys for larvae and pupae, and collected adults from vegetation at residences in eight suburban neighborhoods in Raleigh, NC during the 2002 and 2003 mosquito seasons. Host sources of blood fed mosquitoes were determined by an indirect Enzyme Linked Immunosorbent Assay, using antisera made in New Zealand white rabbits to the blood serum proteins of humans and, domestic and wild animals.
An area-wide management strategy involving a lethal oviposition trap (LOT) placed in the landscape around homes in suburban neighborhoods was evaluated. The trap consisted of a black plastic cup filled with water and containing an oviposition substrate impregnated with an insecticide. Source reduction (SR) of water-filled containers was also evaluated as a management strategy for Ae. albopictus in combination with the LOT and as a stand-alone area-wide approach to control. Analysis of variance did not reveal any significant mosquito suppression (P > 0.05) resulting from the LOT, SR, or the combination of LOT and SR during the 2002 and 2003 mosquito seasons. We determined that the mosquito production potential of a container was a function of its pupal standing crop, density, and
spatial distribution in the landscape.
Spatial statistical methods were used to evaluate impacts of SR of man-made, water-holding containers on the
spatial structure of the population of Aedes albopictus immatures.
Spatial analyses considering the presence or absence of pupae revealed that residences with at least one pupa-positive container tended to be dispersed throughout SR areas and clustered throughout control areas, indicating that SR affected the
spatial distribution of pupae. We used kriging to show the
spatial distribution of oviposition activity within neighborhoods. Areas of high and low egg production existed in most neighborhoods; however,
spatial patterns of oviposition changed between seasons. Oviposition activity peaked in late summer in both the 2002 and 2003 mosquito seasons. Aedes albopictus primarily fed on mammals, but took blood meals from 12 different hosts or host classes, including birds, frogs, and turtles. The largest proportion of blood meals was taken from humans, followed by cats and dogs. Host feeding indices were calculated for human and domestic animal hosts based on the proportion of host specific blood-fed mosquitoes per collection in relation to the number of corresponding specific hosts per residence established from a door-to-door host survey. When host abundance was considered solely, host-feeding indices indicated that Ae. albopictus was more likely to feed on domestic animals. When feeding indices included host abundance that was time-weighted based on potential exposure to mosquitoes, Ae.…

Tracking fishermen : using GIS to characterise spatial distribution of fishing effort in the Tasmanian abalone fishery.

▼ Major collapses of abalone fisheries around the world have been preceded by a spatial serial depletion of abalone populations. As in other fisheries, this serial depletion has been difficult to anticipate and to understand without fine scale monitoring and analysis of spatial effort distribution. In recent years a field of fisheries science has started to evolve which looks at the spatial distribution of fishing effort in commercial fisheries and spatial fleet dynamics, and novel applications of some GIS tools are being developed. Despite the relative health of the Tasmanian abalone fishery (a $A100 million fishery) compared to other abalone fisheries around the world, many aspects of the reporting and assessment process require improvement to ensure sustainability of the fishery. History has shown that reliance on catch and temporal effort data reported at large spatial scales (current Tasmanian practice) is inadequate for assessment of abalone stocks, or for detecting spatial depletion. Traditional fishery independent methods used to estimate population abundance (both relative and absolute) are also inadequate, and prohibitively expensive for monitoring fishery stability.
In this study, GPS data loggers were deployed on abalone fishing boats and set to record latitude and longitude of boat position every ten seconds. Divers wore depth loggers to record information about when divers were actively fishing. A novel aspect of this study is the combination of GPS fishing data and GIS tools, generally applied in animal behaviour analyses, to quantify the spatial distribution of fishing effort as captured by the loggers. The ability of these methods to describe complexity of diver behaviour, concentration of diver effort and contraction of the fishery were assessed.
The use of GPS loggers provided high spatial resolution data on fishing activity, and improved the quality of fishing effort data available. Describing spatial distribution of fishing effort at fine scales captures information about changes in that spatial distribution. Performance measures of Catch Per Unit of Area fished were developed and demonstrated in the context of fishery assessment. Kernel density estimates of fishing activity during single fishing events are proposed as measures of fishing behaviour. Adoption of simple behavioural indices (dive duration as an indicator of fishing success) was proposed to enhance traditional Catch Per Unit Effort based stock-assessment methods. Subject to field validation, the performance measures developed in this study can be used to forewarn fishers and advise managers of depleting fish stocks.

▼ In tissue engineering, cells must be uniformly distributed within 3D scaffolds in order to receive adequate nutrition and oxygen. The objective of this project is to test a novel method to seed cells within a three-dimensional porous chitosan-collagen scaffold to achieve a uniform cell distribution in the Z direction and XY plane. Cells mixed in a collagen solution are seeded to the top of the scaffold and centrifuged to distribute the cells throughout the void spaces of the scaffold. The scaffolds are placed in a CO 2 incubator at 37 °C to allow the collagen-cell solution to gel, thus trapping the cells throughout the scaffold. The cells trapped in a collagen gel are observed for viability, proliferation, and distribution. Fluorescent microscopy is used to view the distribution of CellTracker red and DAPI-labeled cells within the scaffolds. Cell viability and proliferation in the scaffolds are compared to a two-dimensional monolayer cell culture and to cells distributed within three-dimensional collagen gels. The mean major pore size of the optimum dry scaffold is approximately 130 μm with a thickness of 800 μm. Preliminary observations show that the cells attach to the scaffold and are viable. Cell seeding efficiency of a scaffold or collagen gel is increased when seeded within a collagen solution. Due to the viscous nature of the collagen solution, a majority of cells are retained on the top surface of the scaffold. An increase in centrifugation increases cell penetration; however, with a decrease in cell viability. A balance in the viscous nature of the collagen and the centrifugal force has led to a uniform distribution of cells throughout the scaffold. A collagen solution of 2 mg/ml results in the best cell distribution in the XY plane among the samples, but cell growth decreases. The optimum seeding method of those tested was with a collagen solution of 1 mg/ml and a centrifugal force of 840 x g (2200 rpm). This method provided a uniform distribution of cells in the Z direction.

▼ This research seeks to identify the political determinants that account for the uneven geographical
distribution of foreign direct investment (FDI) across Chinese counties. I compare the political determinants of Taiwanese FDI (TDI) and non-Taiwanese FDI site selection across counties in China. I focus on the central-local politics in China, especially the effect of county government autonomy on FDI and TDI site selection. I investigate whether the effect of county government autonomy and its interaction with TDI agglomeration varies across the three economic regions of China (i.e. eastern, central, and western regions). I argue that county government autonomy is critical to attracting inflows of FDI, and its impact is conditional on the existing level of FDI in a given county. Counties with higher autonomy are able to make greater commitments to and involvement in the market economy, have more flexibility to give preferential treatment to FDI and to improve the local investment environment. With the political burden that Taiwanese investors face from the special military and political relationship across the Strait, I argue that TDI is more sensitive to county government autonomy not only for the economic gains like other foreign investors but also for pursuing local protection against the political uncertainties from Beijing and the social instabilities of the local population. I also argue that county government autonomy’s impact on TDI inflow is strongest in the central region due to the less dominating role of the geographic and cultural advantages enjoyed by the eastern region and its better economic, cultural, political and geographic conditions that are lacking in the western region. Using the System General Method of Moment model to analyze the county level FDI/TDI panel data sets, I find autonomy’s impact on future FDI inflows fades with the increases in the existing level of FDI but gets stronger with the increases in the existing level of TDI inflows. I also find county government autonomy’s impact is strongest for the central region when the existing TDI inflows are zero or at the national average level.

▼ This work investigates the effects of mineral
spatial distribution in porous media on dissolution rates. We measured the calcite dissolution rates by using column experiments, which are packed with the same amount of calcite mass but different mineral distributed patterns in quartz-sand column (the mixed, 2-cylinder, 1-cylinmder column). The scale of each column is 2.65 cm in diameter and 10 cm in length. The mixed column has a homogeneously distributed calcite in the quartz column , and the 1-cylinder/2-cylinder column confines all the calcite particles within the middle cylindrical zone(s) that is parallel to the flow injection. We flushed the columns with acidic water at various flow velocities. Experimental data show the dissolution rate of calcite is approximately 1.6 to 2 times slower in the 1-cylinder column than in the mixed column, and the rates are about 1.6-2 orders of magnitude lower under the slowest flow velocity (0.31 m/day) compared to the fast flow velocity (m/day). Ratio (α) demonstrates the mineral
spatial distributed effect playing an important role in column-scale rates. This is, the mineral
spatial distributed effect is more significant under the conditions with fastest flow velocity and less homogeneously distributed reactive minerals (1-cylinder column). In the 1-cylinder column, the 2-D
spatial profile modeling shows that the dissolution rates are larger by orders of magnitude at the calcite-quartz interface than the central region within the middle calcite-packed zone. Also, the range of dissolving calcite area at the calcite-quartz interface becomes wider with the increasing transverse dispersivity and under fast flow velocities. In contrast, transverse dispersivity does not affect local dissolution rates in the mixed column and all the calcite are dissolving. From those observations, we infer that transverse dispersivity caused by different mineral
spatial distribution controls the mass transport in transverse direction. Two calculations in effective surface area are introduced to understand the above observations:(1) total surface area (AT), representing the total calcite surface area by assuming that all the calcite particles are dissolving; (2) effective surface area (Ae), which is the surface area of effectively dissolving calcite at the calcite-quartz interface and inlet. Column-scale bulk rates (mol/s) increase with the increasing Ae values while remain irrelevant to AT values. Also, the Ae values increases with the increasing flow velocities. This suggests that the different measures in the surface area and flow velocities can be the possibilities causing the discrepancies between field and laboratorial measure rates. This work provides the way to minimize the discrepancies in order to approach the calcite dissolution rate under natural subsurface conditions. The surface area of dissolving calcite at the interface of calcite and other non-reactive minerals needs be measured first, and then the rate constant (mol/m2/s) obtained in laboratory work can be used to infer the real rates.…

▼ A epilepsia afeta milhares de pessoas mundialmente, se tornando um problema de saúde pública. Tem-se como objetivo deste estudo avaliar a distribuição espacial dos domicílios de pessoas com epilepsia no municipio de São José do Rio Preto, situado no Estado de São Paulo, Brasil, como também verificar sua distribuição de acordo com sexo, tipo de epilepsia, frequência das crises epilépticas e fatores socioeconômicos. Trata-se de um estudo epidemiológico transversal da epilepsia baseado em arquivos de atendimento primário e de registros computadorizados de ambulatório de hospital terceário, sendo a coleta de dados realizada a partir de 1/1/2003 até 31/12/2012. Foram rastreados um total de 136.512 receitas de fármacos antiepiléticos, com 2377 casos confirmados de pessoas com epilepsia. Foi constatado gênero feminino de maior predominância, em maioria adultos, com tipo de crise focal e esporádicas, referente as classes econômicas, as classes C e D concentram-se maior população acometida pela patologia. Foi verificado estatisticamente que a distribuição dos jovens não teve evidência de associação entre as regiões sociodemográficas estudadas, assim como o sexo, tipos, duração e frequência da crise; a evidência de associação foi encontrada entre as faixas etárias e as regiões sociodemográficas, com idosos predominando nas regiões Sul e Central, crianças e adultos na região Norte. Concluiu-se que este estudo foi capaz de evidenciar com clareza de imagens, a distribuição espacial de pessoas com epilepsia, corroborando com outras pesquisas. Os dados encontrados podem auxiliar em ações preventivas e de melhor assistência a população.
Epilepsy affects several thousand people worldwide, becoming a public health problem. This study aims to evaluate the spatial distribution of dwelling for people with epilepsy in São José do Rio Preto, São Paulo, Brazil, as well as verify their distribution according to sex, type of epilepsy, frequency of epileptic seizures and socioeconomic factors. This is an epidemiological study on epilepsy based on primary care and computerized records of a medical outpatient clinic of a tertiary referral hospital. The data collection was performed from January 1, 2003 to December 31, 2012. A total of 136,512 prescriptions of antiepileptic drugs were screened, with 2377 confirmed cases of people with epilepsy. The female gender was found to be the most prominent in most adults with focal and sporadic seizures concerning the economic classes, in which the classes C and D are responsible for the largest population affected by this condition. It was statistically found that the distribution of young people had no evidence of association between the sociodemographic regions studied, as well as sex, types, duration and frequency of the seizures; evidence of association was found between age groups and socio-demographic areas with the elderly predominating in the South and Central regions, children and adults in the North. It was concluded that this study was able to clearly show the spatial distribution of people…

▼ The theme of this study is
spatial mismatch, a concept that gave rise to an ever-expanding body of research concerned with how and why residential and employment distributions have shifted within cities and across metropolitan areas. The concept grew out of John F. Kain's research on how racial discrimination and segregation affects the
spatial patterns of people/subgroups and jobs in the postwar American urban environment. Specifically, "Housing Segregation" posits that housing-market discrimination is at the root of increased unemployment among inner-city, nonwhite workers; concurrently, the pace and volume of decentralization (of residents and employment) from central-cities reinforces low-income, overwhelmingly African-American isolation and immobility. This study contributes to the New Orleans literature by providing a pre- and post-Katrina snapshot of
spatial mismatch. The analysis addresses research questions aimed at gauging the extent to which mismatch and job-isolation have changed for poor workers in the New Orleans metro area since Hurricane Katrina.

Gorilla nest site data from the Kagwene sanctuary, Cameroon were analyzed to foster an understanding of the nesting behavior of Cross River Gorillas. The main objective of the study was to verify the pattern of nest site distribution in the sanctuary, the influence of environmental covariates and possible interaction between nest sites and between nest sites of two gorilla groups – the Major and Minor groups. Spatial point pattern analysis methods were implemented in the R software environment for this purpose. Overall, we sought to fit models that could best estimate an intensity function for nest site distribution in the sanctuary. Resulting models revealed that nest site distribution does not conform to a Poisson process, and that the data can be better described by a combination of environmental factors and interaction between nest sites. Univariate models fitted to different nest site categories proved to be more useful than bivariate models in defining intensity functions for nest site distribution. The final model category chosen for the data therefore constituted a combination of the effect of covariates and higher-order interaction between nest sites. This set of models, chosen through their AIC values, showed that nest site distribution in the sanctuary exhibits characteristics of attraction so that clustered patterns are observed. Gorillas tend to create hotspots for nest site location, with southern parts of the sanctuary proving to be very much avoided. Intensity tends to increase with increasing distance to the centre of the sanctuary. Coefficients obtained from the models also showed that gorillas prefer constructing nests close to transition vegetation, on steep slopes and generally on east-facing slopes. In the dry season however, colonizing forests exert a greater attraction on nest sites, which can be attributed to the fact that transition zones experience such edge effects as bushfires, and plants that provide food (such as Zingiberaceae) do not bear fruit in this season. These can be assumed to be specific habitat requirements of this subspecies of gorillas. Also, intensity drops with increasing elevation. Interaction parameters obtained from the bivariate models also suggested that there is attraction between nest sites of the Major (sites with more than 6 nests) and the Minor groups. This analysis is the first of its kind for this subspecies, and we recommend that further models can be fitted to include a wider range of covariates (both anthropogenic and natural) as they may be available to expand the scope of the models.

▼ O estudo aborda aspectos da riqueza, atividade reprodutiva, distribuição temporal e espacial dos anfíbios anuros da Floresta Estadual do Uaimií, município de Ouro Preto, Minas Gerais, Brasil. Pela primeira vez é apresentada uma listagem das espécies de anfíbios da área. Para o estudo de inventário foram realizadas campanhas mensais em quatro ambientes amostrais: dois riachos permanentes (Riacho do alojamento -RA e Riacho São Bartolomeu - RSB), um brejo permanente (Brejo da Estrada - BE) e um brejo temporário (Brejo do Campo Rupestre - BCR), entre o período de setembro de 2009 a agosto de 2010. Além das observações nestas áreas amostrais, foram utilizados dados coletados em outras campanhas e em outros ambientes, realizadas na área de estudo. Foram registradas 35 espécies pertencentes às famílias Brachycephalidae (2) Bufonidae (2), Centrolenidae (1), Craugastoridae (1), Cycloramphidae (2), Hylidae (18), Hylodidae (1), Leiuperidae (2), Leptodactylidae (5) e Microhylidae (1). O registro da espécie Hylodes babax, da família Hylodidae, representou o primeiro fora da sua localidade tipo. O conhecimento de informações sobre sua história natural, vocalização e descrição do girino podem ajudar na conservação da espécie. Entre os ambientes amostrados, o BE foi o ambiente mais rico, abrigando 14 espécies, seguido pelo ambiente RSB com oito e RA e BCR com sete espécies. Foram definidos cinco padrões de vocalização ao longo do ano: (1) contínuo: para espécies que vocalizaram durante todos, ou quase todos os meses (N= 2 espécies); (2) prolongado: para espécies com atividade de vocalização associada aos meses chuvosos (N= 11 espécies); (3) sazonal: para espécies com vocalização associada a estação seca (N= 1 espécie); (4) oportunista: para espécies que vocalizaram somente após chuvas (N= 1 espécie) e (5) não definido: para espécies em que não foi possível registrar um padrão definido de vocalização ((N= 7 espécies). Quanto à ocupação ambiental, nove espécies (37,5%) foram encontradas utilizando apenas um único microambiente como sítio de vocalização, enquanto 12 (50%) delas utilizaram dois e apenas três espécies (12,5%) utilizaram três ou mais microambientes. Quanto aos fatores abióticos, houve relação positiva entre a pluviosidade e a riqueza total de espécies (r = 0.6071; p = 0.04) e a riqueza de espécies em atividade de vocalização (r = 0.6255; p = 0.03; Figura 3B), considerando-se os quatro sítios amostrados conjuntamente. A temperatura média do ar não teve influência significativa sobre nenhuma das variáveis. A distribuição espacial e temporal das espécies de anuros varia de acordo com o ambiente que ocupam, parecendo se adequar aos fatores bióticos e abióticos de cada um deles. Cada espécie também parece adequar seus padrões de atividade e ocupação ambiental aos fatores bióticos a que está submetida. Estudos como este contribuem para elucidar aspectos biológicos da anurofauna, confirmando quais são os padrões mais rígidos e quais aqueles menos definidos, sujeitos a alterações segundo as peculiaridades de cada região; além de…

▼ The dwarf succulent genus Lithops (Aizoaceae) is endemic to southern Africa, with 16 species in Namibia. Lithops are vulnerable to a variety of threats and assignment of accurate conservation status is difficult due to insufficient information about population parameters and influence of habitat variables. In addition, taxa are defined according to leaf characters that may be adapted to plant habitat, resulting in over-classification. Plant density, spatial arrangement of plants and habitat profile was investigated in a 1 ha study area in a population of L. pseudotruncatella. Five out of seven plant density estimation methods vastly over- or under-estimated plant number as determined in a census. Plant number in 100 10×10 m test plots was positively associated with a higher percentage cover of gravel and pebbles as opposed to sand or stones, and with a gentle rise as opposed to slopes and depressions. Plant abundance and habitat variables were also evaluated in 9 populations of L. ruschiorum. Evaluation of the 51 and 43 sites of the meticulously studied RUL population, and the remaining 8 populations, respectively, showed that plant density and/or plant number was associated with aspect, slope, soil texture, substrate and geographic distance from the coast. Results are concordant with a strong impact of fog-based precipitation on plant density in the coastal populations, whereas rain is probably more important at RUL, situated further inland. Plant number dropped by 50% in 21 10×10 m plots monitored at RUL over nine years, most likely due to a prolonged drought in 2012–2016. Plant number declined also in some of the 15 plots in the other populations. AFLP markers were employed to study 52 individuals from 7 populations of L. ruschiorum, and 223 individuals from 44 populations representing 15 Lithops species and 23 taxa in total. An AMOVA demonstrated low levels of genetic differentiation between populations of L. ruschiorum, and a significant but rather weak isolation-by-distance pattern. Analyses of genetic structuring and phylogenetic relationships identified several groups of closely related species, while subspecific taxa often overlapped considerably. Main reason for the overall low variability in Lithops is probably a rapid and recent diversification of succulents after the global expansion of arid environments in the late Miocene. Three nomenclatural changes were made, affecting: (1) L. optica and L. herrei, (2) L. amicorum and L. karasmontana, and (3) subspecies bella and eberlanzii of L. karasmontana.

▼ Les bactéries ont colonisé toutes les niches écologiques de la planète. Plus précisément, les sols sont l’hôte de la plus grande biodiversité terrestre, la faune microbienne. Cette grande diversité de bactéries et leur relative ubiquité rendent difficile l’identification des variables contrôlant la distribution spatiale des bactéries vivant dans le sol. Comme les bactéries du sol jouent un rôle important dans les grands cycles biogéochimiques globaux, il est important de mieux comprendre les variables qui peuvent influencer la composition bactérienne des sols. Dans cette thèse, nous émettons l'hypothèse que l'hétérogénéité de la composition de la communauté bactérienne apparaît à la même échelle spatiale que l'hétérogénéité des propriétés physico-chimiques du sol. Afin de comprendre la relation entre la composition bactérienne des sols (à l’échelle d’une carotte de sol jusqu’à l’échelle d’une région entière du nord de la France) et les paramètres physico-chimiques du sol à différentes échelles spatiales, nous allons utiliser une approche intégrant des données issues d’analyses SIG (Système d’Information Géographique), d’analyses physico-chimiques du sol et d’analyses des communautés bactériennes du sol. A travers une suite de trois expérimentations, nous allons répondre à trois questions: Est-ce qu’une pression environnementale uniforme à une plus grande échelle (cm) peut atténuer l’hétérogénéité microbienne à micro-échelle? Est-ce que les variables ayant une distribution spatiale suivant un gradient géographique sont des variables structurant fortement la distribution spatiale des bactéries à l’échelle de ce même gradient? Est-ce que certains bio-indicateurs à grandes échelles peuvent intégrer des groupes de variables pour modéliser la distribution des bactéries pour une région entière ?
The bacteria have colonized all the niches of the planet. Specifically, soils are home of the largest terrestrial biodiversity, microbial fauna. This great diversity of bacteria and their relative ubiquity make it difficult to idendified variables driving the spatial distribution of bacteria living in the soil. As soil bacteria play a significant role in the main global biogeochemical cycles, it is important to better understand the variables that can influence bacterial composition of soils. In this thesis, we hypothesize that heterogeneity of the bacterial community composition appears at the same scale level as the heterogeneity of soil physicochemical properties. In order to understand the relationship of bacterial composition of soils (from core experiment to field study in large region in the northern France) and soil factors at different spatial scales, we will use an approach coupling GIS tools, soil physico-chemical analysis and 16S rRNA gene NGS. With Three set of experiment we will answer three questions: Can a uniform environmental pressure at a larger scale (cm) overcome microbial micro-scale heterogeneity? Are geographical gradients strong drivers of the microbial community structure at the scale of the gradient? Do…

Despite recent methodological improvements and higher data availability, the
Climate Change (CC) and Armed Conflict (AC) studies are suffering from poor data
and inappropriate research designs (e.g., Incompatibilities of scale). This study fills
the gaps by taking the climate conflict analyses into a different scale (e.g., 55 km x
55 km sub-national cell/year) and uses high resolution Geo-referenced data sets. This
study presents the results from 10 years (1991-2000) of observations and a rigorous
modelling methodology to understand the effects of climate change on the conflict
occurrence in the Eastern Africa. The main objective of the study is to identify and
understand the conflict dynamics, verify the pattern of conflict distribution, possible
interaction between the conflict sites and the influence of climatic covariates of
conflict outbreak. We have found that if the climate related anomaly increases, the
probability of armed conflict outbreak also increases significantly. To identify the
effect of climate change on armed conflict we have modeled the relationship between
them, using different kinds of point process models and Spatial Autoregressive
(SAR) Lag models for both spatial and spatio-temporal cases. In modelling, we have
introduced one new climate indicator, termed as Weighted Anomaly Soil Water
Index (WASWI), which is a dimensionless measure of the relative severity of soil
water containment indicating in the form of surplus or deficit. In all the models the
coefficients of WASWI were found negative and to be significant, predicting armed
conflict at 0.05 level of significance for the whole period. The conflicts were found
to be clustered up to 200 kilometers and the local level negative relationship between
conflict and climate suggests that change in WASWI impacts changes in AC by -
0.1981 or -0.1657. We have also found that the conflict in the own cell associated to
a ( app. 0.7) increase in the probability of conflict occurances in the neighbouring
cell and also to a (app. 0.6) increase of the following years (spatio-temporal). So,
climate change indicators are a vital predictor of armed conflict and provides a
proper predictive framework for conflict expectation. This study also provides a
sound methodological framework for climate conflict research which encompasses
two big approaches, point process modelling and lattice approach with careful
modelling of spatial dependence, spatial and sptio-temporal autocorrelation, etc.

Protest in Europe where analyzed to foster an understanding of the distribution and
the behaviour of those during from 2000 to 2010 time frame.
The main object of this study is to discover if there is a relation between economic,
social and other variables available in Eurostat in order to discover a pattern in the
protests in Europe. For this purpose, least squared method and spatial point pattern
analysis method were applied in the R Software environment. The final output
indicates that variables can’t explain a cause-effect relation of protests due to tis
behaviour is complex and Europe is an inhomogeneous area. In the other hand, we
saw that protest tend to increase mostly when other protest have happened in the
past.
Protest location are scattered within the European megalopolis, and reveals attraction
to some capitals some hot spots patterns are observed. They are mostly located in
urban areas, close to the borders with other European countries. The resulting models
discovered that protest/events distributions do not imitate an inhomogeneous Poisson
process and thus we tried to model the behaviour describing special interaction
between locations of protests.
The best interaction model was chosen by computing different distances. We
analyzed the whole Europe area and due a strong influence of United Kingdom we
computed the same model to Germany, France, United Kingdom and Spain. Finally,
a step further spatial-temporal analysis was taken only for Spain.
This analysis is one of the first analyses set by the recently launched Global Database
of Events, Language, and Tone (GDELT), a big free online data base of over 250m
events and 300 categories including riots and protests codified from world news
sources.
After this analysis we recommend, further analysis should contain models that apply
border contagion including time.

▼ Background: The global
distribution of tuberculosis is skewed heavily toward low-and-middle
income countries, which accounted for about 87% of all estimated incident cases. Ethiopia is a
low-income country in east Africa that remains highly afflicted by tuberculosis, with varying
degrees of magnitudes across settings. However, there is a dearth of studies clarifying about the
spatial epidemiology of the disease in Ethiopia. Lack of such information may contribute to the
partial effectiveness of tuberculosis control programs.
Objectives: The specific objectives of this study were: 1) to detect
spatial and space-time
clustering of tuberculosis, 2) to estimate
spatial risk of tuberculosis
distribution using limited
spatial datasets, and 3) to identify ecological factors affecting
spatial distribution of tuberculosis
in Gurage Zone, Southern Ethiopia.
Methods: The study data were obtained from different sources. Specific objectives 1 and 3
included a total of 15,805 tuberculosis patients diagnosed at health facilities in Gurage Zone
during 2007 to 2016, whereas specific objective 2 included 1,601 patients diagnosed in 2016.
The geo-location and population data were obtained from the Central Statistical Agency of
Ethiopia (specific objectives 1-3). The altitude data were extracted from global digital elevation
model v2 (specific objective 2). The normalized difference vegetation index data were derived
from the moderate resolution imaging spectroradiometer imagery, and the temperature and
rainfall data were obtained from the Meteorological Agency of Ethiopia (specific objective 3).
The global Moran’s I, Kulldorff’s scan and Getis-Ord
statistics were used to analyze purely
spatial and space-time clustering of tuberculosis (specific objective 1). The geostatistical kriging
approach was applied to estimate the
spatial risk of tuberculosis
distribution (specific objective
2). The
spatial panel data analysis was used to estimate the effects of ecological factors on
spatial
distribution of tuberculosis prevalence rate (specific objective 3).
Results: The prevalence of tuberculosis varied from 70.4 to 155.3 cases per 100,000 population
in the Gurage Zone during 2007 to 2016. Eleven purely
spatial clusters (relative risk: 1.36–14.52,
P-value < 0.001) and three space-time clusters (relative risk: 1.46–2.01, P-value < 0.001) for
high occurrence of tuberculosis were detected. The clusters were mainly concentrated in border
areas of the zone. The predictive accuracies of ordinary cokriging models have improved with
the inclusion of anisotropy, altitude and latitude covariates, the change in detrending pattern
from local to global, and the increase in size of
spatial dataset (mean-standardized error = 0, rootxi
mean-square-standardized error = 1, and average-standard error ≈ root-mean-square error). The
spatial risk of tuberculosis was estimated to be higher (i.e., tuberculosis prevalence rate > 100
cases per 100,000 population) at western, northwest, southwest and southeast parts of the study
area,…

▼ An efficient forest management requires accurate and cost-effective measurements of forest inventory parameters. The cost of LiDAR surveys are directly dependent on the number and size of validation plots as well as the sampling density of points needed to adequately estimate forest inventory parameters. In this study we investigate (i) the
spatial variability of the forest stand, i.e., the effect of the area chosen on the prediction of forest parameters and (ii) the relation between prediction accuracy and sampling point density for the estimation of top height, basal area and volume at plot level. Assessment of the stand’s
spatial variability was carried out by comparing the accuracy of the top height estimations, using the 99th percentile of a normalised
distribution of points, over areas of different size. Original sampling density was synthetically reduced to 10, 5, 4, 3, 2, 1, 0.50, 0.33, 0.25 and 0.20 returns per m2. Forest parameters were subsequently estimated for each point density by means of 99th percentile (top height) and linear regression models (basal area and volume). Predictions were validated using 11 stands, each containing one 50 50 m plot. Results show that the optimum area for forest parameters prediction is 1600 m2 with an average top height accuracy of 95.05% and a standard deviation of 3.41%. Larger sizes will merely increase the cost of field data collection without improving the accuracy. Interestingly, top height predictions were slightly more accurate for lower point densities. Linear equations yielded RMSEs of 3.28-5.28 m2/ha and 29.41-36.04 m3/ha for basal area and volume respectively. There were therefore small differences in terms of accuracy of predicted parameters for different point densities, which indicates that once a good DTM is created, future LiDAR surveys can be accomplished over the same area at lower sampling densities, and thus reducing the costs but without disregarding estimation accuracy.

▼ Introdução: A hipertensão arterial (HA) é uma Doença Crônica Não Transmissível (DCNT) que contabiliza 9,4 milhões das mortes a cada ano. Esta doença é caracterizada por níveis elevados de pressão arterial (PA) e se apresenta no Brasil com uma alta prevalência. O uso de tabaco, dieta não saudável, atividade física insuficiente e o consumo de álcool estão entre os fatores de risco para o acometimento da hipertensão arterial. Objetivo: Verificar a distribuição e a autocorrelação espacial da prevalência de hipertensão arterial e fatores de risco associados em adultos no Brasil, no período de 2008 e 2009. Métodos: Trata-se de um estudo ecológico utilizando dados nacionais, no período de 2008 e 2009, para a faixa etária de 20 a 59 anos. As fontes dos dados são: Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (VIGITEL), Pesquisa de Orçamentos Familiares (POF) e Sistema de Vigilância Alimentar Nutricional (SISVAN). Primeiramente a caracterização e descrição das variáveis foram desenvolvidas. Mapas temáticos foram criados para a visualização da distribuição geográfica da hipertensão arterial e os fatores de risco no Brasil. O teste de adesão a curva de normalidade foi aplicado para as variáveis de interesse. Para o desenvolvimento da análise espacial, foi utilizado o Índice de Moran Global e Local para a identificação da autocorrelação e dos padrões espaciais. O coeficiente de correlação de Spearman foi calculado, a fim de testar a correlação entre as variáveis. Posteriormente, foi construído um modelo de regressão linear múltiplo seguindo o esquema stepwise. Foi realizado a análise de Moran do resíduo para verificar a presença de cluster espacial dos resíduos da análise de regressão. Resultados: As menores prevalências de hipertensão arterial foram encontradas na região Norte, e em alguns estados do Nordeste. O Rio de Janeiro foi o estado que se destaca com a maior prevalência de HA encontrada. A análise do Índice de Moran Global apontou que somente a prevalência de hipertensão arterial não apresentou padrão de cluster. O coeficiente de correlação de Spearman indicou que a prevalência de hipertensão arterial apresentou correlação positiva com todas as variáveis independentes, e que a maior correlação da hipertensão arterial foi com o consumo médio de sódio. Na análise de regressão linear múltipla, a única variável independente que explicou a prevalência de hipertensão arterial foi o consumo médio de sódio. A análise de Moran do resíduo não demonstrou dependência espacial entre a prevalência de hipertensão arterial e o consumo médio de sódio. Conclusões: É possível concluir que o acometimento da HA em adultos brasileiros atinge patamares que demonstram a necessidade de maiores investigações sobre a sua distribuição no país a fim de garantir a melhor abordagem de prevenção e intervenção em cada área geográfica. As técnicas de análise espacial e geoprocessamento se mostram como uma nova ferramenta, que podem ser úteis na gestão e na determinação de programas que contribuem para o…

▼ The Northeast has a record of fighting to reduce disparities. In late 1950, the state intervened through SUDENE, organizing and planning the promotion of development through industrialization. This study aims to identify the characteristics of the industrialization of the Northeast and evolution of formal employment in the metropolitan area of Cariri, located in the southern state of Ceará, in the case of the municipalities of Crato, Juazeiro do Norte and Barbalha (CRAJUBAR) in decades of 1990 and 2000. The assumption permeates the SUDENE with public policies to encourage the industry, causing profound changes in the cities studied. The results indicate that the Cariri since the 1960 has been benefiting the programs implemented by SUDENE. With the implementation of these programs, with in a set of circumstances based on local vocations and state policies, there was a
spatial distribution industry, triggering a growth and development on the provision of formal jobs in the industrial sector

▼ The Northeast has a record of fighting to reduce disparities. In late 1950, the state intervened through SUDENE, organizing and planning the promotion of development through industrialization. This study aims to identify the characteristics of the industrialization of the Northeast and evolution of formal employment in the metropolitan area of Cariri, located in the southern state of Ceará, in the case of the municipalities of Crato, Juazeiro do Norte and Barbalha (CRAJUBAR) in decades of 1990 and 2000. The assumption permeates the SUDENE with public policies to encourage the industry, causing profound changes in the cities studied. The results indicate that the Cariri since the 1960 has been benefiting the programs implemented by SUDENE. With the implementation of these programs, with in a set of circumstances based on local vocations and state policies, there was a
spatial distribution industry, triggering a growth and development on the provision of formal jobs in the industrial sector

▼ Estrutura da vegetação de um cerradão no Nordeste do Maranhão). A estrutura da vegetação de uma área de cerradão, localizado no município de Urbano Santos-MA, foi avaliada através da análise do padrão de distribuição espacial. A amostragem utilizou o método de quadrante, sendo alocados 399 pontos em três transectos paralelos, distribuídos sistematicamente a uma distancia de 200m, com o ponto de inicio do primeiro transecto sorteado. A distância entre os pontos amostrais foi de 10 metros, com critério de inclusão de 3cm de perímetro ao nível do solo. Foram amostrados 1596 indivíduos distribuídos em 70 espécies e 32 famílias. Seis espécies totalizaram 49,86% IVI total, sendo Plathymenia reticulata (candeia) a espécie mais importante. Do total de indivíduos amostrados 75% estão concentrados em 14 espécies (20% das espécies). Dezessete espécies ocorreram com apenas um indivíduo (espécies raras). A diversidade da área e a equabilidade foram altas. A distribuição dos diâmetros em classes de tamanho indicou que a maioria dos indivíduos (70,4%) está concentrada na primeira classe e 61,5% dos indivíduos mortos encontraram-se também na 1 classe de diâmetro. A comparação florística entre sete levantamentos realizados em áreas de cerrado no Estado do Maranhão indicou elevada heterogeneidade e baixa similaridade entre as formações, ocorrendo uma maior similaridade florística entre as localidades com maior proximidade geográfica apenas nas análises que incluíram valores de abundância das espécies.
Vegetation structure of a Cerrado in the northeastern of Maranhão, Brazil). The vegetation structure of a Cerrado area, located at the Urbano Santos municipality, MA, Brazil, was evaluated through the analysis of spatial distribution. The Point-Centered Quarter method was used for sampling, being allocated 399 points in three parallel transects, systematically placed at a 200m distance for each other, with the starting point of the first transect randomized. The distance between sampling points was 10m, with inclusion criteria 3cm perimeter at soil level. The 1596 sampled individuals were distributed in 70 species and 32 families. Six species totalized 49.86% of total IVI, being Plathymenia reticulata (candeia) the most important species. Seventy five percent of the total sampled individuals are concentrated in 14 species (20% of the total of species). Seventeen species occurred with a single individual (rare species). The diversity of the area and the equability were high. The distribution of the diameters in size classes indicated that the most of individuals (70.4%) is concentrated in the first class up to diameter, and 61,5% of dead individuals are also in the 1st diameter class. The floristic comparison among seven surveys carried out in Cerrado areas in Maranhão State indicated a high heterogeneity and low similarity among the studied vegetation, and the nearest areas showed the most floristic similarity only when the analyses with abundance values of species were performed.
