P-Value, Confidence Intervals, and Statistical Inference: A New Dataset of Misinterpretation
2017
Statistical inference is essential for science since the twentieth century (Salsburg, 2001). Since it's introduction into science, the null hypothesis significance testing (NHST), in which the P-value serves as the index of “statistically significant,” is the most widely used statistical method in psychology (Sterling et al., 1995; Cumming et al., 2007), as well as other fields (Wasserstein and Lazar, 2016). However, surveys consistently showed that researchers in psychology may not able to interpret P-value and related statistical procedures correctly (Oakes, 1986; Haller and Krauss, 2002; Hoekstra et al., 2014; Badenes-Ribera et al., 2016). Even worse, these misinterpretations of P-value …

Regional differences in returns to education for entrepreneurs versus wage earners
2010
Many studies suggest that rates of return to schooling are lower for entrepreneurs than for employees, although the opposite has also been reported. This paper analyses the returns to education for entrepreneurs in urban and rural regions in Finland and compares these to the returns for wage earners. These areas show different rates of self-employment, higher rates being found in rural areas and lower rates in urban areas. The analysis is based on a rich, register-based dataset that includes a 7% random sample of all Finns. To avoid potential sources of bias, Mincer-type income equations are estimated using different estimation procedures. The results show regional variation in returns to e…
Development of Household Income Towards Modern Welfare Economics in Latvia
2020
Latvia in international comparisons is among the countries with rather low average income for households but rather high differences in income in households, especially in highest income households (richest quintile) characterised with significant indicators of variability in euro zone countries by Household and Consumption Survey conducted buy Bank of Latvia by methodology of European Central Bank in all eurozone countries and according EU- SILC (European Union Statistics on Income and Living Conditions) data. This current research is devoted to analysis of development of income and variability of income of households in Latvia in comparison with other OECD countries and eurozone countries…
Role of Education and Training on Income in Different Regions of Latvia
2019
Latvia is often critisised by international institutions on rising gap for income differences in several social groups. This current research is devoted to analyse of role of education and training on income level. Research methods used: scientific publications and previous conducted research analysis, analysis of EU-SILC data on differences in income depending from education level, from regions and from territory (urban/rural), interviews of regional authorities on life-long training arrangements and applications in regions with lower income level. Data analysis methods: descriptive statistics (indicators of central tendency or location, indicators of variability), cross-tabulations of hou…
Tuition fees and student effort at university
2018
Abstract This paper presents theoretical and empirical evidence that an increase in tuition fees may boost university students’ academic effort. We examine the tuition fee rise introduced in 2012 by Spanish universities, where students register and pay for their chosen modules and fees increase each time students retake a module until they pass it. Data refer to students of economics, business and medicine at the University of Valencia during 2010–2014. The fact that some students pay fees in full while others are exempt from payment provides an identifying source of variation that we exploit using a flexible difference-in-differences methodology.
Revista electrónica de investigación y evaluación educativa
2016
Este estudio evalúa un procedimiento nuevo para el análisis “micro-sociométrico” de los patrones relacionales de género en el alumnado adolescente, lo que se analiza aplicando Análisis de Correspondencias Múltiples (ACM). El propósito del estudio es desarrollar y validar la Escala de Preferencias Relacionales de Género (EPRG), con el fin de obtener datos válidos y fiables que permitan reconocer la predisposición de las chicas y los chicos adolescentes a relacionarse con sus iguales; y, si las relaciones que establecen están condicionadas por la socialización diferencial de género que propone el patriarcado (Bosch, Ferrer & Alzamora, 2006; Lagarde, 1996; Lomas, 2007; Lorente, 2007; Rodríguez…
3He-MRI-based measurements of intrapulmonarypO2 and its time course during apnea in healthy volunteers: first results, reproducibility, and technical…
2000
We applied a recently developed method of following the time course of the intrapulmonary oxygen partial pressure p(O2)(t) during apnea by (3)He MRI to healthy volunteers. Using two imaging series with different interscan times during two breathholds (double acquisition technique), relaxation of (3)He due to paramagnetic oxygen and depolarization by RF pulses were discriminated. In all four subjects, the temporal evolution of p(O2) was found to be linear, and was described by an initial partial pressure p(0) and a decrease rate R. Also, regional differences of both p(0) and R were observed. A correlation between p(0) and R was apparent. Finally, we discuss limitations of the double acquisit…
Diagnosing Occupational Stress in Romanian Organisations
2014
Abstract The study investigates the complex topic of occupational stress, based on a comprehensive model of stress diagnosis and management for romanian employees (N=1026 participants), at individual and organizational level. The following multidimensional components of the dynamic stress process are measured with the romanian adapted version of Pressure Management Indicator (PMI, Williams & Cooper, 1998 ; PMI-RO, Brate, 2004 , Brate, 2006 , Brate, 2008 ): stressors, effects, individual differences and coping strategies. Specific significant influences and associations between stressors, individual differences, coping strategies and perceived effects of occupational stress are presented. Fu…
Method Effects and Gender Invariance of the Rosenberg Self-esteem Scale: A Study on Adolescents
2015
AbstractRosenberg's self-esteem scale has been extensively used in all areas of psychology to assess global self-esteem (Rosenberg, 1965, 1979). Its construct validity, and specifically its factor structure, has almost from the beginning been under debate. More than four decades after its creation the cumulated evidence points that the scale measures a single trait (self-esteem) but confounded by a method factor associated to negatively worded items. The aim of the study is to examine the measurement invariance of the RSES by gender and test potential gender differences at the latent (trait and method) variable level, while controlling for method effects, in a sample of Spanish students.
