In geostatistical studies, spatial dependence can generally be described by means of the semivariogram or, in complementary form, with a single index followed its categorization to classify degree such dependence. The objective this study was construct for (SDI) proposed Seidel and Oliveira (2014) order variability terms weak, moderate, strong Theoretical values were constructed from different degrees dependence, which served as basis calculation SDI. view form distribution SDI descriptive...

O semivariograma possibilita uma avaliação visual da dependência espacial, mas sem resultar diretamente em um valor numérico único que expresse a mensuração de tal dependência. Contudo, partir dos parâmetros estimados do modelo teórico ajustado ao experimental, é possível construir medida dessa espacial. Atualmente, há dois índices na literatura, com uso cada vez mais frequente; porém, inadequações nesses existentes. objetivo deste trabalho foi propor novo índice para medir espacial dados...

Were used 231 sample raw from 63 producerscolleted 6 30 September 2004. analyzed flowingvariables: percentage water; fat, acidity degree Dornic;density g/cm3. Both two methods show three for producerswhich 52 stay same both methods.

Urgency is a complaint of sudden, compelling desire to pass urine, which difficult defer, caused by involuntary contraction the detrusor muscle during bladder-filling stage. To enable inhibition, electrotherapy resources such as transcutaneous tibial nerve stimulation (TTNS) and parasacral electrical (PTES) have been used. The objective this study publish protocol that aims investigate whether urgency decreases after treatment with both techniques.This randomized controlled clinical trial...

The assessment of spatial variability environmental variables such as soil properties is important for site-specific management. A geostatistical index that allows quantifying and characterizing the structure fundamental in this context. Thus, study aimed to develop a new dependency index, called Spatial Dependence Measure (SDM) spherical, exponential, Gaussian, cubic, pentaspherical, wave semivariogram models; comparing it with some indexes available literature. SDM also [...]

O objetivo deste estudo foi utilizar a Teoria de Resposta ao Item (TRI) como ferramenta para avaliação da satisfação dos alunos das disciplinas Estatística Básica e Geral Universidade Federal Santa Maria (UFSM). Foi aplicado o Modelo Gradual (MRG), por meio do qual criada uma escala medida satisfação, em que foram posicionados os itens respondentes, numa mesma unidade medida. Os resultados mostraram MRG TRI adequado análise dados, permitindo identificação problemáticos, construção níveis...

The rice stem bug, Tibraca limbativentris Stal (Hem.: Pentatomidae), is one of the main insect pests in Brazilian crops. Knowledge its spatiotemporal distribution can support development an effective sampling system and improve IPM strategies. This study aimed to map bug flooded crop Southern Brazil. Flooded was scouted for two seasons estimate densities. Four occurrence categories were observed: no insect, only adults, nymphs, both phases. relationship between phenological stages...

The aim of this work was to propose a correction for Exponential and Gaussian models due the different percentages explanation contribution. procedure consisted in determining value called k, based on percentage contribution that one wants reach. Correction k calculated 95% 99.99% contribution, showing it is possible obtain mathematical expressions models. In addition, generalized these two were constructed. For better observation behavior values scenario spatial dependence simulated, from...

For psychometric tests, following were used: Confirmatory Factor Analysis; composite reliability, convergent against Engagement work; Occupational self-efficacy; Overall resilience; General Health Questionnaire;...

Abstract: This study aims to propose a spatial dependence index (and its classification), from the concept of correlation areas, for Cubic, Pentaspherical and Wave models. The index, called Spatial Dependence Index (SDI), covers following parameters: range (a), nugget effect (C 0 ) contribution 1 ), beyond considering maximum distance (MD) between sampled points model factor (MF). proposed unlike most used in literature, considers influence parameter describe dependence, highlighting...

A avaliação da significância dependência espacial é importante para que se possa realizar uma inferência formal sobre a hipótese nula de não existência em Geoestatística. Com o presente estudo, objetivou-se construir um teste ausência espacial, melhor decisão ou dados geoestatísticos. Para construção do levou-se consideração as características dos modelos ajustados ao semivariograma e, hipótese, inicialmente, foram definidos e estatística gerada partir conceito área obtida no semivariograma....

While organizations want to develop software products with reduced cost and flexible scope, stories about the applicability of agile practices improve project development performance in industry are scarce focused on specific methodologies such as Scrum XP. Given these facts, this paper aims investigate, through practitioners' perceptions value, which being used two criteria for projects-cost scope. Using a multivariate statistical technique known Exploratory Factor Analysis (EFA), results...

Abstract: The objective of this work was to assess the relationship between depth irrigation water and larval infestation by Oryzophagus oryzae in flooded rice crop. Water were evaluated upper levee, levees, lower levee. data subjected descriptive statistical geostatistical analyses. highest occurs field areas with greater depth, which is typical spatial distribution O. larvae aggregate type depends on depth.

Plant resistance is a key strategy for the management of Oryzophagus oryzae (Costa Lima) (Coleoptera: Curculionidae), an important pest in South American rice paddies.

Abstract: In Geostatistics, the use of measurement to describe spatial dependence attribute is great importance, but only some models (which have second-order stationarity) are considered with such measurement. Thus, this paper aims propose measurements assess degree in power model adjustment phenomena. From a premise that considers equivalent sill as estimated semivariance value matches point where adjusted curves intersect, it possible build two indexes evaluate dependence. The first one,...

Abstract The rice water weevil, Oryzophagus oryzae (Coleoptera: Curculionidae), is an economically important pest of flooded paddies throughout South America, and species with similar life histories are present in many rice-producing regions globally (collectively referred to here as RWWs). Plant resistance a key strategy for management RWWs; however, the mechanisms responsible RWWs poorly understood. We investigated morphoanatomical biochemical plant traits potentially involved O. ....
