<div class="WordSection1"><p>O Nordeste Brasileiro é uma das regiões mais problemáticas no que se refere à disponibilidade de água, portanto, se tem necessidade de atentar a práticas e métodos para desenvolvimento dessa região, visto que as condições climáticas, a hidrologia e sua vegetação são de extrema importância para compreender como esse ambiente se forma. O objetivo principal deste trabalho é verificar e avaliar a variabilidade climática da microrregião de Sousa, através da análise espaço-temporal mensal e anual da sua precipitação, identificando-se, assim, os períodos secos e chuvosos da área estudada com o auxílio do Índice de Anomalia de Chuva (IAC). Os dados pluviométricos utilizados na pesquisa correspondem às séries mensais de precipitação no período de 1994 a 2017 fornecidos pela AESA, para a avaliação temporal, espacial e para o cálculo do Índice de Anomalia de Chuva (IAC). A microrregião de Sousa apresenta dois períodos distintos, um período de cinco meses chuvosos e outro com sete meses secos. A distribuição espacial da precipitação da microrregião possui áreas bem distintas, onde a maior concentração de precipitação se localiza na parte sudoeste, em contrapartida, a região noroeste e em um ponto na parte central apresentaram valores baixos de precipitação.</p><p><strong>Palavras-chave:</strong> Períodos Secos, Períodos Chuvosos e Índice de Anomalia de Chuva.</p><p> </p><p align="center">STUDY OF SPACE-TIME PLUVIOMETRIC VARIABILITY IN THE SOUSA MICROREGION, PARAÍBA</p><p><strong>Abstract</strong></p><p>The Brazilian Northeast is one of the most problematic regions in terms of water availability. Therefore, it is necessary to consider the practices and methods for the development of this region, since climatic conditions, hydrology and vegetation are of extreme importance to understand how this environment is formed. The main objective of this work is to verify and evaluate the climatic variability of the Sousa microregion, through the monthly and annual space-time analysis of its precipitation, thus identifying the dry and rainy periods of the studied area with the aid of the Anomaly Index Rainfall (IAC). The rainfall data used in the research correspond to the monthly rainfall series from 1994 to 2017 provided by the EFSA for the temporal and spatial evaluation and for the calculation of the Rainfall Anomaly Index (IAC). The Sousa microregion has two distinct periods, one period of five rainy months and the other with seven dry months. This work has a relevance in the area of ecology, which through the results help to collaborate with the development of the microregion, which through its managers dominate the knowledge of the stations pointed to abundance and water scarcity for the anthropic activities.</p><p><strong>Key-words: </strong>Dry Periods, Rainy Periods, and Rain Anomaly Index.</p></div>

Given the great variability of the precipitation in the Brazilian Northeast, it is necessary to use climate indexes for its monitoring. In this sense, this work aims to present a study of the space-time variation in the rainfall precipitation at the Salgado Basin, located in the state of Ceará, using the Rainfall Anomaly Index (RAI) as a tool. In order to do so, daily precipitation data from seven meteorological stations were used for the period between 1974 and 2015. From the data obtained, the RAI was calculated and plotted in spatial distribution maps. It was possible to observe that the rainy season at the basin lasts from January to April, and the driest period of the year lasts from July to October. The historical series presented drier years than rainy ones. A variation in the RAI within the basin was evidenced, and the region corresponding to Chapada do Araripe was more humid. The years with the most extreme anomalies were related to SSTA events, which favored its occurrence.

The article examines a 30-year experience of collective ethnography in the sugarcane plantations of Brazil's Northeast. Over this period, the research group has worked in different temporal and spatial contexts, continually exchanging its findings. The author draws on her experience as part of the research group in order to focus on the conditions of entering the field, the seasonal variations and geographic displacements, the research group's morphology and the overall implications for anthropological knowledge. Debates over ethnography have neglected the relationship between the social conditions in which anthropologists carry out their work and what they are able to write about the social world. This article sets out to fill this gap.

<p>El objetivo de este estudio fue establecer el patrón espacio-temporal de la malaria en Matina y relacionarlo con factores ambientales. Se utilizaron tecnologías espaciales para capturar, almacenar, analizar y visualizar información relacionada con localidades y viviendas. Los atributos no espaciales fueron analizados usando pruebas paramétricas y no paramétricas. Los datos fueron obtenidos de las bases de datos de casos clínicos del Área Rectora del Ministerio de Salud en Matina. Se presentan los descriptores puntuales de las localidades positivas para los años 2005 y 2006 y en los grupos de viviendas positivo y negativo en la localidad piloto. Se propone una clasificación de áreas macroambientales en el cantón y se relaciona con la distribución de la Incidencia Parasitaria Anual (IPA). Se identificaron factores de riesgo a nivel de vivienda en la localidad piloto. Se describe la ocurrencia temporal de la actividad malárica en el cantón. El patrón espacio-temporal que se presenta en este informe puede servir de línea base para estudiar cambios que podrían ocurrir en el futuro.</p><p> </p><p>SPACE-TIME ANALYSIS OF MALARIA IN MATINA, LIMÓN, COSTA RICA</p><p><strong>ABSTRACT</strong><br /> The purpose of this study was to describe the space-time pattern of the disease, and relate it to environmental factors. Spatial technologies were used to collect, store, analyze and display information regarding locations and household locations. Non-spatial attributes were analyzed using parametric and non parametric tests. The information was obtained from databases of clinical cases form the Governing Area of the Health Ministry in Matina. Centrographic parameters were calculated for localities within Matina and for households within the pilot location. Parasitic Incidence (IPA) was associated with a proposed environmental classifiation for Matina. At the household level, risk factors were determined. The temporal pattern of the disease in Matina is described. A similar temporal trend is shown for households within the pilot location. This is the fist time that the information collected in the Matina Governing Area is used to describe the spatial patterns of malaria.<br /> This pattern will be useful as a comparative baseline for future studies.</p><p> </p><p><span><br /></span></p>

This paper deals with the cartographical presentation of cultural succession in Greek space-time associated with core concepts of geographic and historical education. The pedagogic value of this study is to develop five distinct skills: sense of time-scale, historical and geographic comprehension, spatial analysis and interpretation, ability to perform geo-historical research, and procedure of geohistorical decision-making. The methodology is based on the calibration of a set of criteria for each cultural site that covers the topics of economy, geomorphology, society, religion, art and science. Further analysis of these data forms a geodatabase. In addition, palaeogeographic and historical maps of the cultural sites derived by the geodatabase provide information about temporal and spatial changes. As result, students will be able to develop a multidimensional and interdisciplinary approach, in order to reconstruct the evolution of the site
