Cilvēkfaktors noliktavu darbā un preventīvie pasākumi
2021
“Cilvēkfaktors noliktavu darbā un preventīvie pasākumi”. Darba autors: Artūrs Poštars. Darba zinātniskais vadītājs: Dr. sc. admin., prof. Henrijs Kaļķis. Darbs izklāstīts uz 69 lpp., ietver 21 attēlu, 6 tabulas, 8 pielikumus un 62 informatīvos avotus. Maģistra darbs sastāv no četrām daļām. Pirmajā daļā ir apkopota un analizēta literatūra par cilvēkfaktora ietekmi un radītajām kļūdām darba procesos, kā arī būtiskākajiem darba vides riskiem noliktavu darbā. Literatūras analīze uzrāda, ka cilvēkfaktora ietekme ir ļoti cieši saistīta ar pastāvošajiem ergonomiskajiem darba vides riskiem. Otrajā daļā ir aprakstītas pētījumā izmantotās metodes: anketēšana, Somijas 5 baļļu metode, slodzes galveno r…
El frente popular: ¿Qué clase de acontecimiento? Historiografía y actualidad de las investigaciones sobre el Frente Popular
2016
The development of the historiography on the Popular Front has focused on three main fields, political history, social history and cultural history. However, the fragmentation of the object of study has hindered a more global reflection on the Popular Front, as one major event which constituted both a political and cultural project and an unprecedented social and political alliance with a broad popular movement. A fundamental event, embedded in the long life of French history, with significant consequences for the social area of the working class, the start of a new culture of social democracy French-style and as a reference which nourished the fights of the French Resistance as well as its…
Climate Change Mitigation Potentials of Carbon Labels in the Aviation Industry
2018
This chapter discusses the climate change mitigation potentials of carbon labels in the aviation industry. As this study shows, there are significant differences in the environmental performance of individual flights, even when operated on the same route or by the same airline. Selecting one flight over another can significantly reduce the carbon dioxide emissions of a single air passenger. Nevertheless, the currently available measures, such as carbon calculators, are not capable of presenting these differences, leaving air passengers with no means of comparing individual flights. Therefore, the use of carbon labels could be highly beneficial because it would give air passengers the opport…
Investigating the Reliability of Stationary Design Rainfall in a Mediterranean Region under a Changing Climate
2023
Extreme rainfall events have been more frequent in recent decades, potentially as a climate change effect. This has been leading to a higher risk of the failure of existing hydraulic infrastructures, and to a higher awareness regarding the unreliability of design rainfall calculated with reference to historical data recorded in the last century. With this in mind, the present study questions the stationary assumption of the rainfall Depth–Duration–Frequency curves commonly used in Sicily, the biggest island of the Mediterranean Sea. Quantiles derived from the most up-to-date regional method, regarding Sicily, based on observations in the period 1928–2010, have been compared with those extra…
Basal ice formation in snow cover in Northern Finland between 1948 and 2016
2018
Abstract Basal ice formation in the terrestrial snow cover is a common phenomenon in northern circumpolar areas, one having significant impacts on ecosystems, vegetation, animals and human activities. There is limited knowledge on the spatial and temporal occurrence of basal ice formation because of the sparse observation network and challenges involved in detecting formation events. We present a unique dataset on the annual extent of ice formation events in northern Finland between 1948 and 2016 based on reindeer herders’ descriptions of the cold season in their management reports. In extreme years, basal ice can form over wide geographical extents. In approximately half of the herding dis…
Mediterranean coccolith ecobiostratigraphy since the penultimate Glacial (the last 145,000years) and ecobioevent traceability
2015
The Mediterranean Sea is a miniature ocean ideal to test the response of marine ecosystems to amplified orbital and suborbital climate changes. Here we present coccolith data from a Sardinia Channel gravity core (Arcose C_33) analysed over the last 145,000 years, with a mean resolution of about 900 years. The study highlights that regional phytoplankton assemblages underwent significant modifications between the penultimate glacial and the last interglacial, as well as between the last glacial and the Holocene. The N ratio palaeoproductivity index suggests reduced productivity levels and the development of a deep nutricline during the last interglacial and the Holocene. Within the last glac…
Cognitive Deficits and Associated ERP N400 Abnormalities in FXTAS With Parkinsonism
2018
Objective: To examine cognitive deficits and associated brain activity in fragile X-associated tremor/ataxia syndrome (FXTAS) patients with parkinsonism (FXTp+), in relation to FXTAS patients without parkinsonism (FXTp-), and normal elderly controls (NC). Methods: Retrospective reviews were performed in 65 FXTAS patients who participated in the event-related brain potential (ERP) study and also had either a videotaped neurological examination or a neurological examination for extrapyramidal signs. Parkinsonism was defined as having bradykinesia with at least one of the following: rest tremor, postural instability, hypermyotonia, or rigidity. Eleven FXTp+ patients were identified and compare…
Polygenic association between attention-deficit/hyperactivity disorder liability and cognitive impairments.
2022
AbstractBackgroundA recent genome-wide association study (GWAS) identified 12 independent loci significantly associated with attention-deficit/hyperactivity disorder (ADHD). Polygenic risk scores (PRS), derived from the GWAS, can be used to assess genetic overlap between ADHD and other traits. Using ADHD samples from several international sites, we derived PRS for ADHD from the recent GWAS to test whether genetic variants that contribute to ADHD also influence two cognitive functions that show strong association with ADHD: attention regulation and response inhibition, captured by reaction time variability (RTV) and commission errors (CE).MethodsThe discovery GWAS included 19 099 ADHD cases …
The Contribution of Event-Related Potentials to the Understanding of Sign Language Processing and Production in the Brain : Experimental Evidence and…
2022
Functional neuroimaging allows investigation of the timing properties of the brain mechanisms underlying covert language processing. This paper presents a review of the use of the neuroimaging technique called Event-Related Potentials (ERPs) in sign language (SL) research. In the field of neurolinguistics, ERPs have been widely used in the study of spoken language, but their use in SL is still rare. Studying the neurocognitive aspects of SL could lead to a better understanding of the specific processing of SL in the brain. This review outlines the basic theoretical and methodological principles of ERPs. We focus on three groups of ERPs that are particularly relevant to SL processing and pro…
