Several studies have compared the prediction accuracy of different types of techniques with emphasis placed on linear and stepwise regressions, and Case-based Reasoning (CBR). We believe the use of only one type of CBR technique may bias the results, as there are others that may also be used for effort prediction. This paper has two objectives. The first is to compare the prediction accuracy of...
Introduction: One of the objectives of educational systems is to raise the level of students' ability to improve their academic performance. The aim of present study was to determine the relationship between emotional self-control, alexithymia, and academic excitement with academic burnout in students with learning disabilities.

This study is a cross-sectional descriptive correlational and its statistical population was all high school students in Ardabil, which 197 students (102 boys and 95 girls) from four high schools selected using m...
among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
This study aimed to investigate the role of early maladaptive schemas in the marital satisfaction of Kermanshah Police Officers. This descriptive study was the correlational type. Two hundred married women working in Kermanshah Police Department were selected as the sample. Young schema questionnaire first measurement tools, Enrich marital satisfaction scale was realistic and wife. The Pearson...
Many variable selection methods for linear regression depend critically on tuning parameters that control the performance of the method, e.g., “entry” and“stay” significance levels in forward and backward selection. However, most methods do not adapt the tuning parameters to particular data sets. We propose a general strategy for adapting variable selection tuning parameters that effectively es...
The study aimed to investigate students’ self-efficacy, self-esteem, and attitude as determinants of their writing performance. The participants for the study were 373 South Gonder Zone Preparatory School students who were chosen using multistage sampling technique. Questionnaire and writing test were employed to gather data. Pearson’s Correlation technique was used to analyze the associations ...
This exploratory study is an empirical test of a model based on a hacking framework. Variables were measured using nonreactive, secondary data obtained from sixty months of official statistical data, instead of relying on self-reports and surveys. Using stepwise regression, we found support for several of the model predictions. Reconnaissance was positively related to the vulnerability represen...
