Automašīnas gaismas ietekme uz redzes asumu miopijas gadījumā mezopiskos gaismas apstākļos

2018

Maģistra darbs rakstīts latviešu valodā uz 28 lapām, satur 18 attēlus un 84 atsauces uz literatūras avotiem. Darba mērķis: izpētīt, kā mainās redzes asums fotopiskos apstākļos salīdzinot ar mezopiskiem apstākļiem un apstākļos, kad uz dalībnieku tiek izstarota automašīnas luktura gaisma. Metode: uzdevumā redzes asums tika noteikts FrACT programmā uz datora ekrāna. Tests sastāv no baltiem Landolta gredzena optotipiem uz melna fona. Redzes asums tika salīdzināts fotopiskos, mezopiskos un no automašīnas luktura izstarotā ksenona un halogēnās spuldzes apgaismojuma apstākļos. Secinājumi: Mezopiskos apstākļos redzes asums ir zemāks nekā fotopiskos apstākļos. Halogēnas gaismas ietekme uz redzes asu…

SHORT-TERM VARIABILITY OF 24H SYSTOLIC BLOOD PRESSURE IS ASSOCIATED WITH MICROALBUMINURIA IN PATIENTS WITH PRIMARY HYPERTENSION

2015

Objective: Limited and conflicting data are available about the association between shortterm blood pressure (BP) variability and urinary albumin excretion rate (uAER). The objective of our study was to analyze the relationships between microalbuminuria, defined as an uAER between 20 and 200mg/ min, and shortterm BP variability, assessed as average real variability (ARV), weighted standard deviation (SD) of 24h BP, and as SD of daytime and nighttime BP. Design and method: The study population consisted of 315 untreated essential hypertensives with normal estimated glomerular filtration rate (> 60ml/min/1.73 m2), which underwent 24h ambulatory BP monitoring and 24h uAER determination. Result…

Midlife in the United States (MIDUS 2), 2004-2006

2007

In 1995-1996, the MacArthur Midlife Research Network carried out a national survey of 7,108 Americans aged 25 to 74 (MIDLIFE IN THE UNITED STATES (MIDUS), 1995-1996 [ICPSR 2760]). The purpose of the study was to investigate the role of behavioral, psychological, and social factors in understanding age-related differences in physical and mental health. The study was innovative for its broad scientific scope, its diverse samples (which included twins and the siblings of main sample respondents), and its creative use of in-depth assessments in key areas (e.g., daily stress and cognitive functioning). A description of the study and findings from it are available at http://www.midus.wisc.edu. Wi…

Examining mediators of change in wellbeing, stress, and depression in a blended, Internet-based, ACT intervention for university students

2020

A coach-guided Acceptance and Commitment Therapy (ACT) intervention that uses a blended approach of two face-to-face and five online sessions (iACT; N = 33) has been found to be more effective than a waiting-list control condition (WLC; N = 35) at enhancing the wellbeing of university students while also reducing stress and depression. The present study explored possible mediators of change that may account for the outcomes of the study. Mediation analyses revealed that changes in the non-reactivity subscale of mindfulness mediated changes in wellbeing, depression, and stress in the iACT group. In addition, changes in the sense of coherence subscale of meaningfulness mediated changes in all…

An EEMD Aided Comparison of Time Histories and Its Application in Vehicle Safety

2017

In the context of signal processing, the comparison of time histories is required for different purposes, especially for the model validation of vehicle safety. Most of the existing metrics focus on the mathematical value only. Therefore, they suffer the measuring errors, disturbance, and uncertainties and can hardly achieve a stable result with a clear physical interpretation. This paper proposes a novel scheme of time histories comparison to be used in vehicle safety analysis. More specifically, each signal for comparison is decomposed into a trend signal and several intrinsic mode functions (IMFs) by ensemble empirical mode decomposition. The trend signals reflect the general variation a…

Longitudinal analysis of Spanish doctoral theses in education (1841-2012)

2014

This article analyzes the research output of doctoral theses in the field of Education defended in Spain from 1841-2012. It offers a quantified global and diachronic view of such series. As a landmark to note is the fact that until 1954, obtaining a doctoral degree was centralized at the Complutense University of Madrid. They are used as search engines bibliographic databases: TESEO and institutional repositories, and basic bibliography of the area to carry out the collection of the sample. The contrasting hypothesis is to verify whether the time series partially follows the pattern of growth of the science of Derek J. de Solla Price. The central finding is that the Spanish production of do…

Le cimetière du second âge du Fer de Lailly au-delà de l'eau (Yonne) : découvertes anciennes et fouilles récentes

2023

Die Nekropole von Lailly Au-delà de l’Eau (Departement Yonne) war 1927 entdeckt worden und wurde1934, 1936 und 1937 und zum letzten Mal 2012 teilweise ausgegraben. Die Untersuchung der in den Depots der Museen von Senswiederentdeckten Grabbeigaben und die systematische Aufarbeitung der Grabungsarchive der Société archéologique de Sens habenes ermöglicht, einen Teil der geschlossenen Fundkontexte zu rekonstruieren und eine Belegungschronologie dieser kleinen Nekropolevorzuschlagen, deren großes wissenschaftliches Potenzial noch in situ erforscht werden muss. Die Studie der Grabsitten hat es zudemerlaubt, die Funde in den regionalen und überregionalen soziokulturellen Kontext zu einzuordnen

Parents’ and children’s beliefs about learning Lithuanian language and their relationships to Lithuanian language achievement in Grade 2

2023

Straipsnyje nagrinėjamos 2-os klasės mokinių ir jų tėvų įsitikinimų apie lietuvių kalbos mokymąsi sąsajos su mokinių pasiekimais. Nustatyta, kad mokinių įsitikinimai apie savo gebėjimus, susidomėjimas lietuvių kalba, tėvų lūkesčiai bei 2-os klasės pasiekimai tarpusavyje siejasi teigiamais ryšiais. Kontroliuojant vaiko lytį, tėvų išsilavinimą bei 1-os klasės pasiekimus, geresnius pasiekimus 2-oje klasėje prognozuoja aukštesni tėvų lūkesčiai ir geresni vaikų savų gebėjimų vertinimai. Esminiai žodžiai: įsitikinimai apie gebėjimus, užduoties vertė, tėvų lūkesčiai, lietuvių kalbos pasiekimai. Previous studies have shown that as early as elementary school, children’s language skills are determine…
