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…
Ruolo del rumore ambientale in sistemi complessi di natura biologica
2010
La Fisica dei Sistemi Complessi ha recentemente assunto un ruolo sempre più importante nella descrizione dei sistemi biologici a causa delle interazioni, sia deterministiche sia rumorose o “randomiche”, di tali sistemi con l’ambiente. La presenza del rumore diviene particolarmente rilevante nella trattazione dei sistemi biologici in ambito medico. In questo lavoro vengono presentati due diversi sistemi: i) un modello di dinamica di popolazioni che descrive lo sviluppo delle cellule tumorali responsabili della Leucemia Mieloide Cronica (CML); ii) un modello stocastico che riproduce la crescita di batteri in alimenti di origine animale. Nel primo sistema viene utilizzato un approccio Monte Ca…
Relationship between inbreeding and milk production traits in two Italian dairy sheep breeds.
2022
The effects of inbreeding in livestock species breeds have been well documented and they have a negative impact on profitability. The objective of this study was to evaluate the levels of inbreeding in Sarda (SAR, n = 785) and Valle del Belice (VdB, n = 473) dairy sheep breeds and their impact on milk production traits. Two inbreeding coefficients (F) were estimated: using pedigree (FPED), or runs of homozygosity (ROH; FROH) at different minimum ROH lengths and different ROH classes. After the quality control, 38,779 single nucleotide polymorphisms remained for further analyses. A mixed-linear model was used to evaluate the impact of inbreeding coefficients on production traits within each …
Cardiorespiratory Fitness and the Risk of Serious Ventricular Arrhythmias: A Prospective Cohort Study.
2019
Cardiorespiratory fitness (CRF) is an established risk factor for cardiovascular disease outcomes. However, the relationship of CRF with risk of ventricular arrhythmias (VAs) is unknown. We aimed to assess the prospective association of CRF with the risk of serious VAs. Cardiorespiratory fitness, as measured by maximal oxygen uptake, was assessed using a respiratory gas exchange analyzer in 2299 middle-aged men in the Kuopio Ischemic Heart Disease prospective cohort. We corrected for within-person variability in CRF levels using data from repeated measurements 11 years apart. During median follow-up of 25.3 years (interquartile range, 18.7-27.2 years), 73 serious VAs were recorded. The age-…
Beta-decay studies for applied and basic nuclear physics
2020
In this review we will present the results of recent beta-decay studies using the total absorption technique that cover topics of interest for applications, nuclear structure and astrophysics. The decays studied were selected primarily because they have a large impact on the prediction of a) the decay heat in reactors, important for the safety of present and future reactors and b) the reactor electron antineutrino spectrum, of interest for particle/nuclear physics and reactor monitoring. For these studies the total absorption technique was chosen, since it is the only method that allows one to obtain beta decay probabilities free from a systematic error called the Pandemonium effect. The me…

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…
Dead wood profile of a semi-natural boreal forest – implications for sampling
2019
Dead wood profile of a forest is a useful tool for describing forest characteristics and assessing forest disturbance history. Nevertheless, there are few studies on dead wood profiles, including both coarse and fine dead wood, and on the effect of sampling intensity on the dead wood estimates. In a semi-natural boreal forest, we measured every dead wood item over 2 cm in diameter from 80 study plots. From eight plots, we further recorded dead wood items below 2 cm in diameter. Based on these data we constructed the full dead wood profile, i.e. the overall number of dead wood items and their distribution among different tree species, volumes of different size and decay stage categories. We …
Māsu komunikācijas prasmes un to efektivitātes vērtējums neatliekamās medicīnas nodaļā
2015
Bakalaura darba tēma – Māsu komunikācijas prasmes un to efektivitātes vērtējums neatliekamās medicīnas nodaļā. Tēmas aktualitāti nosaka randomizēti pētīju saistībā ar māsu komunikācijas prasmju apmācību un to efektivitātes pierādījumu turpmākā medicīnas aprūpes sniegšanā un iznākumu novērtēšanā. Māsu komunikācijas prasmes apmācība pierādīja, ka māsu prasmes komunicēt bija efektīvākas psihosociālā atbalsta sniegšanā, palielināja prasmes konfliktu risināšanā. Darba mērķis ir noskaidrot māsu komunikācijas prasmes efektivitāti neatliekamās medicīnas nodaļās.

Satisfação Profissional no Docente Dominicano: Antecedentes Profissionais
2019
Resumen La satisfacción laboral del colectivo docente ha sido estudiada desde diversas perspectivas, debido a los importantes efectos que esta puede tener tanto a nivel económico como a nivel organizacional. La muestra empleada en este trabajo se compone de 978 docentes dominicanos, y fue obtenida mediante un muestreo estratificado, y, por tanto, representativo de la población. En este estudio se examina un modelo de ecuaciones estructurales en el cual el contexto de trabajo y las condiciones laborales afectan el burnout y el engagement de los profesores. A su vez, se plantea que burnout y engagement afectan la satisfacción laboral docente. El modelo ajustó a los datos: x2(223)= 1089.9, p<.…
