    Description

    This paper analyzes current practices in psychology in the use of research methods and data analysis procedures (DAP) and aims to determine whether researchers are now using more sophisticated and advanced DAP than were employed previously. We reviewed empirical research published recently in prominent journals from the USA and Europe corresponding to the main psychological categories of Journal Citation Reports and examined research methods, number of studies, number and type of DAP, and statistical package. The 288 papers reviewed used 663 different DAP. Experimental and correlational studies were the most prevalent, depending on the specific field of psychology. Two-thirds of the papers reported a single study, although those in journals with an experimental focus typically described more. The papers mainly used parametric tests for comparison and statistical techniques for analyzing relationships among variables. Regarding the former, the most frequently used procedure was ANOVA, with mixed factorial ANOVA being the most prevalent. A decline in the use of non-parametric analysis was observed in relation to previous research. Relationships among variables were most commonly examined using regression models, with hierarchical regression and mediation analysis being the most prevalent procedures. There was also a decline in the use of stepwise regression and an increase in the use of structural equation modeling, confirmatory factor analysis, and hierarchical linear modeling. Overall, the results show that recent empirical studies published in journals belonging to the main areas of psychology are employing more varied and advanced statistical techniques of greater computational complexity.

    Description

    ABSTRACT: The mode of production of scientific knowledge has become complex, leading to the use of research methodological elements that also investigate subjective issues. This study aims to analyze characteristics of PhD theses that adopted the qualitative approach, defended at a Postgraduate Program in Education (PPGE) of a University of the Northeast Region of Brazil, 2013-2016 quadrennium. The theoretical basis of the work is based on contributions from Evandro Ghedin, Marcos Zanette, Marli André and Maria Amélia Franco. To achieve the proposed objective, a quali-quantitative documentary research was developed, based on the identification and analysis of the categories: theme, method, data collection procedure and data analysis technique, synthesized by grouping data extracted from theses abstracts. It was found that, of the amount of 57 theses defended in the period considered, 87.7% (n=50) used a qualitative approach, although only 32.0% (n=16) of these explain this approach in their summary. Public policy and teacher education are the most present among themes. 42.0% (n=21) of the theses clearly indicate the research method, with emphasis on documentary research. There are multiple data collection procedures in them, especially interview and document collection. In 46.0% (n=23) of the theses, the data analysis technique is specified, mainly content analysis. However, it is considered important that researchers in the field of Education clearly inform all the methodological elements of their theses in their abstracts.

    SPATIALLY ADAPTIVE SEMI-SUPERVISED LEARNING WITH GAUSSIAN PROCESSES FOR HYPERSPECTRAL DATA ANALYSIS GOO JUN * AND JOYDEEP GHOSH* Abstract. A semi-supervised learning algorithm for the classification of hyperspectral data, Gaussian process expectation maximization (GP-EM), is proposed. Model parameters for each land cover class is first estimated by a supervised algorithm using Gaussian process regressions to find spatially adaptive parameters, and the estimated parameters are then used to initialize a spatially adaptive mixture-of-Gaussians model. The mixture model is updated by expectationmaximization iterations using the unlabeled data, and the spatially adaptive parameters for unlabeled instances are obtained by Gaussian process regressions with soft assignments. Two sets of hyperspectral data taken from the Botswana area by the NASA EO-1 satellite are used for experiments. Empirical evaluations show that the proposed framework performs significantly better than baseline algorithms that do not use spatial information, and the results are also better than any previously reported results by other algorithms on the same data.

    Description

    Electronic health records (EHRs) have been widely adopted in recent years, but often include a high proportion of missing data, which can create difficulties in implementing machine learning and other tools of personalized medicine. Completed datasets are preferred for a number of analysis methods, and successful imputation of missing EHR data can improve interpretation and increase our power to predict health outcomes. However, use of the most popular imputation methods mainly require scripting skills, and are implemented using various packages and syntax. Thus, the implementation of a full suite of methods is generally out of reach to all except experienced data scientists. Moreover, imputation is often considered as a separate exercise from exploratory data analysis, but should be considered as art of the data exploration process. We have created a new graphical tool, ImputEHR, that is based on a Python base and allows implementation of a range of simple and sophisticated (e.g., gradient-boosted tree-based and neural network) data imputation approaches. In addition to imputation, the tool enables data exploration for informed decision-making, as well as implementing machine learning prediction tools for response data selected by the user. Although the approach works for any missing data problem, the tool is primarily motivated by problems encountered for EHR and other biomedical data. We illustrate the tool using multiple real datasets, providing performance measures of imputation and downstream predictive analysis.

    Description

    Analytical Method Development is a crucial process in the field of scientific research and quality control. It involves creating and optimizing techniques to accurately and precisely analyze substances, compounds, or materials of interest. The primary goal is to establish reliable methods that can identify, quantify, and characterize various components within a sample. During the method development phase, scientists carefully choose suitable instruments, such as chromatographs, spectrometers, or titrators, and develop specific procedures to achieve the desired results. The process often requires iterative experimentation and data analysis to fine-tune the parameters and ensure robustness and reproducibility. Accurate analytical methods are essential in various industries, including pharmaceuticals, environmental monitoring, food safety, and more. They play a vital role in ensuring product quality, safety, and compliance with regulatory standards. In summary, analytical method development is an indispensable aspect of scientific investigations, enabling researchers to derive meaningful data and make informed decisions based on the analysis of complex samples. https://www.silverscreenandroll.com/users/sterinlab https://www.ridiculousupside.com/users/sterinlab https://www.sonicsrising.com/users/sterinlab https://www.swishappeal.com/users/sterinlab https://www.bringonthecats.com/users/sterinlab https://www.burntorangenation.com/users/sterinlab https://www.crimsonandcreammachine.com/users/sterinlab https://www.frogsowar.com/users/sterinlab https://www.ourdailybears.com/users/sterinlab https://www.rockchalktalk.com/users/sterinlab https://www.smokingmusket.com/users/sterinlab https://www.vivathematadors.com/users/sterinlab https://www.widerightnattylite.com/users/sterinlab https://www.musiccitymiracles.com/users/sterinlab https://www.stampedeblue.com/users/sterinlab https://www.celticsblog.com/users/sterinlab https://www.libertyballers.com/users/sterinlab https://www.netsdaily.com/users/sterinlab https://www.postingandtoasting.com/users/sterinlab https://www.blazersedge.com/users/sterinlab

    Description

    dataset and Octave/MatLab codes/scripts for data analysis Background: Methods for p-value correction are criticized for either increasing Type II error or improperly reducing Type I error. This problem is worse when dealing with thousands or even hundreds of paired comparisons between waves or images which are performed point-to-point. This text considers patterns in probability vectors resulting from multiple point-to-point comparisons between two event-related potentials (ERP) waves (mass univariate analysis) to correct p-values, where clusters of signiticant p-values may indicate true H0 rejection. New method: We used ERP data from normal subjects and other ones with attention deficit hyperactivity disorder (ADHD) under a cued forced two-choice test to study attention. The decimal logarithm of the p-vector (p') was convolved with a Gaussian window whose length was set as the shortest lag above which autocorrelation of each ERP wave may be assumed to have vanished. To verify the reliability of the present correction method, we realized Monte-Carlo simulations (MC) to (1) evaluate confidence intervals of rejected and non-rejected areas of our data, (2) to evaluate differences between corrected and uncorrected p-vectors or simulated ones in terms of distribution of significant p-values, and (3) to empirically verify rate of type-I error (comparing 10,000 pairs of mixed samples whit control and ADHD subjects). Results: the present method reduced the range of p'-values that did not show covariance with neighbors (type I and also type-II errors). The differences between simulation or raw p-vector and corrected p-vectors were, respectively, minimal and maximal for window length set by autocorrelation in p-vector convolution. Comparison with existing methods: Our method was less conservative while FDR methods rejected basically all significant p-values for Pz and O2 channels. The MC simulations, gold-standard method for error correction, presented 2.78±4.83% of difference (all 20 channels) from p-vector after correction, while difference between raw and corrected p-vector was 5,96±5.00% (p = 0.0003). Conclusion: As a cluster-based correction, the present new method seems to be biological and statistically suitable to correct p-values in mass univariate analysis of ERP waves, which adopts adaptive parameters to set correction.

Description

This paper analyzes current practices in psychology in the use of research methods and data analysis procedures (DAP) and aims to determine whether researchers are now using more sophisticated and advanced DAP than were employed previously. We reviewed empirical research published recently in prominent journals from the USA and Europe corresponding to the main psychological categories of Journal Citation Reports and examined research methods, number of studies, number and type of DAP, and statistical package. The 288 papers reviewed used 663 different DAP. Experimental and correlational studies were the most prevalent, depending on the specific field of psychology. Two-thirds of the papers reported a single study, although those in journals with an experimental focus typically described more. The papers mainly used parametric tests for comparison and statistical techniques for analyzing relationships among variables. Regarding the former, the most frequently used procedure was ANOVA, with mixed factorial ANOVA being the most prevalent. A decline in the use of non-parametric analysis was observed in relation to previous research. Relationships among variables were most commonly examined using regression models, with hierarchical regression and mediation analysis being the most prevalent procedures. There was also a decline in the use of stepwise regression and an increase in the use of structural equation modeling, confirmatory factor analysis, and hierarchical linear modeling. Overall, the results show that recent empirical studies published in journals belonging to the main areas of psychology are employing more varied and advanced statistical techniques of greater computational complexity.
