Poczucie jakości życia a rozbieżność w systemie „ja”– różnice między studentami kierunków społecznych i technicznych

2020

Głównym celem badań jest ustalenie predyktorów osobowościowych odnoszących się do nowego modelu poczucia jakości życia w zróżnicowanej grupie studentów. Badania oparto na teorii rozbieżności w systemie „ja” E. T. Higginsa oraz Modelu Osobowościowo-Aksjologicznym B. Mróz. Metoda. Przebadano 64 studentów pedagogiki i 62 studentów elektrotechniki. W badaniach zastosowano Test Przymiotnikowy ACL, Zmodyfikowany Kwestionariusz Poczucia Jakości Życia oraz wywiad i obserwację. Wyniki. Osoby z niską rozbieżnością w systemie „ja” osiągały znacząco wyższe wyniki w Kompetencjach, Relacjach i Autonomii, będącej elementami Modelu Osobowościowo-Aksjologicznego. Analiza regresji krokowej wskazała, że najsi…

On overall sampling plan for small area estimation

2017

The time and budget restrictions in survey sampling can impose limits on the area sample sizes. This may reduce the possibility to obtain area-specific and population parameters estimates with adequate precision. Market research companies and institutes for producing official statistics face frequently this problem. Various models and methods for small area estimation (SAE) have been developed to solve this problem. The sample allocation must support the selected model and method to ensure efficient estimation and must be implemented in the design phase of the survey. The proposed allocation is developed by incorporating auxiliary information, a model, and an estimation method. The estimate…

Testing refined shell-model interactions in the sd shell: Coulomb excitation of 26Na

2015

Background: Shell-model calculations crucially depend on the residual interaction used to approximate the nucleon-nucleon interaction. Recent improvements to the empirical universal sd interaction (USD) describing nuclei within the sd shell yielded two new interactions—USDA and USDB—causing changes in the theoretical description of these nuclei. Purpose: Transitionmatrix elements between excited states provide an excellent probe to examine the underlying shell structure. These observables provide a stringent test for the newly derived interactions. The nucleus 26Na with 7 valence neutrons and 3 valence protons outside the doubly-magic 16O core is used as a test case. Method: A radioactive b…

Testing and implementing a new approach to estimating interregional output multipliers using input-output data for South Korean regions

2020

Flegg's location quotient (FLQ) is a useful tool for estimating intraregional output multipliers. This paper uses it as one component when estimating interregional multipliers. Using statistical information criteria and official data for 16 South Korean regions, it is found that the best approach is to combine the FLQ with a simple trade model. The paper explains how the proposed procedure can be implemented for both multiple and individual regions, and also how a region-specific value for the unknown parameter δ in the FLQ formula can be determined. Finally, an illustrative case study of one of the regions is carried out.

Comparison of Machine Learning Methods in Stochastic Skin Optical Model Inversion

2020

In this study, we compare six different machine learning methods in the inversion of a stochastic model for light propagation in layered media, and use the inverse models to estimate four parameters of the skin from the simulated data: melanin concentration, hemoglobin volume fraction, and thicknesses of epidermis and dermis. The aim of this study is to determine the best methods for stochastic model inversion in order to improve current methods in skin related cancer diagnostics and in the future develop a non-invasive way to measure the physical parameters of the skin based partially on the results of the study. Of the compared methods, which are convolutional neural network, multi-layer …

Predicting sugar consumption : Application of an integrated dual-process, dual-phase model

2017

Excess consumption of added dietary sugars is related to multiple metabolic problems and adverse health conditions. Identifying the modifiable social cognitive and motivational constructs that predict sugar consumption is important to inform behavioral interventions aimed at reducing sugar intake. We tested the efficacy of an integrated dual-process, dual-phase model derived from multiple theories to predict sugar consumption. Using a prospective design, university students (N = 90) completed initial measures of the reflective (autonomous and controlled motivation, intentions, attitudes, subjective norm, perceived behavioral control), impulsive (implicit attitudes), volitional (action and c…

Shell-model study on event rates of lightest supersymmetric particles scattering off 83Kr and 125Te

2016

We investigate the elastic and inelastic scattering of lightest supersymmetric particle (LSP) dark matter off two possible target nuclei, 83Kr and 125Te. For the nuclear-structure calculations, we employ the nuclear shell model using recently generated realistic interactions. We have condensed the nuclear-physics contribution to a set of nuclear-structure factors that are independent of the adopted supersymmetric (SUSY) model. Total event rates are then easily calculated by combining the nuclear-structure factors with SUSY parameters of choice. In particular, 125Te shows promise as a detector material with both the elastic and inelastic channels yielding an appreciable nuclear response. pee…
