Literatūras žanra/formas priekšmetu veidošana: salīdzinošais aspekts
2018
Maģistra darbs "Literatūras žanra/formas priekšmetu veidošana: salīdzinošais aspekts" izstrādāts ar mērķi, lai noskaidrotu literatūras žanra/formas priekšmetu lietderību un nepieciešamību tos ieviest LNB. Pētījuma gaitā tiek analizētas tās bibliotēkas, kas jau sekmīgi izstrādā un ievieš literatūras žanra/formas priekšmetus. Pragmatisma un žanra teorijas atziņas tiek piemērotas bibliotekārā darba kataloģizēšanas procesu izstrādei. Rezultātu iegūšanai tiek izmantotas kvalitatīvas un kvantitatīvas metodes. Pētījumā tiek iegūti apstiprinoši rezultāti, literatūras žanra/formas priekšmetu lietderībai un nepieciešamībai.
History Matters: Colonial‑Based Connectivity and Foreign Headquarter Location Choice
2022
AbstractIn this study, we argue that European countries’ extensive relationships with former colonies represent a location factor that attracts foreign headquarter investments. The strategic role of foreign headquarters as coordinators, opportunity detectors, and global bridgeheads makes the location choice of headquarter activities sensitive to historical-based institutional connections. Drawing on a sample of 2230 foreign headquarter investments in Europe, we find that the stronger the combined effect of historical connections and current economic relationships with former colonies, the higher the probability of attracting headquarter investment projects. We refer to this combined charact…
Antipredatory function of head shape for vipers and their mimics.
2011
Most research into the adaptive significance of warning signals has focused on the colouration and patterns of prey animals. However, behaviour, odour and body shape can also have signal functions and thereby reduce predators' willingness to attack defended prey. European vipers all have a distinctive triangular head shape; and they are all venomous. Several non-venomous snakes, including the subfamily Natricinae, commonly flatten their heads (also known as head triangulation) when disturbed. The adaptive significance of this potential behavioural mimicry has never been investigated. We experimentally tested if the triangular head shape typical of vipers offers protection against predation.…
Pain neuroscience education and physical exercise for patients with chronic spinal pain in primary healthcare: a randomised trial protocol.
2019
AbstractBackgroundChronic musculoskeletal pain affects more than 20% of the population, and the prevalence is increasing, causing suffering, loss of quality of life, disability, and an enormous expenditure on healthcare resources. The most common location for chronic pain is the spine. Many of the treatments used are mainly passive (pharmacological and invasive) and poor outcomes. The treatments currently applied in the public health system do not comply with the recommendations of the main clinical practice guidelines, which suggest the use of educational measures and physical exercise as the first-line treatment. A protocol based on active coping strategies is described, which will be eva…
Modulation of the Endocannabinoids N-Arachidonoylethanolamine (AEA) and 2-Arachidonoylglycerol (2-AG) on Executive Functions in Human.
2013
Animal studies point to an implication of the endocannabinoid system on executive functions. In humans, several studies have suggested an association between acute or chronic use of exogenous cannabinoids (Δ9-tetrahydrocannabinol) and executive impairments. However, to date, no published reports establish the relationship between endocannabinoids, as biomarkers of the cannabinoid neurotransmission system, and executive functioning in humans. The aim of the present study was to explore the association between circulating levels of plasma endocannabinoids N-arachidonoylethanolamine (AEA) and 2-Arachidonoylglycerol (2-AG) and executive functions (decision making, response inhibition and cognit…
Galvassāpju izplatība Latvijas Universitātes medicīnas studentu vidū
2022
Ievads: Galvassāpju traucējumi, galvenokārt primārie, tiek uzskatīti par nopietnām globālām veselības problēmām, kas izraisa ievērojamu invaliditātes slogu slimniekiem, lai arī paradoksālā kārtā, bieži tiek ignorēti un nenovērtēti. Cilvēki savos produktīvajos gados irvisvairāk skartā grupa, un to vidū ir arī studenti. Mērķis: Pētījuma mērķis bija apkopot Latvijas Universitātes medicīnas studentu galvassāpju epidemioloģiskos un klīniskos raksturojumus, lainoteiktu cefalģijas izplatību, novērtētu riska faktorus, provocējošos faktorus, galvassāpju ietekmi un to mazināšanu ar medikamentiem, kā arī noskaidrot iespējamos iemeslus, kādēļ pētāmā populācija izvairās no specializētas galvassāpju trau…
Lethal rupture of post-traumatic aneurysm of the vertebral artery case report.
2009
Abstract Traumatic aneurysms or dissections of the vertebral artery have been reported in patients who have suffered minor craniofacial injuries in traffic accidents. A case is reported of ruptured traumatic vertebral artery aneurysm due to closed head injury without without penetrating injuries or skull fractures. The macroscopic and histological findings relevant to the vertebral wall were compatible with post-traumatic aneurysm; the rupture of the wall was assumed to be caused by sepsis and local infiltration of inflammatory cells.
Head-to-head comparison of contemporary heart failure risk scores.
2021
Altres ajuts: acords transformatius de la UAB Aims: Several heart failure (HF) web-based risk scores are currently used in clinical practice. Currently, we lack head-to-head comparison of the accuracy of risk scores. This study aimed to assess correlation and mortality prediction performance of Meta-Analysis Global Group in Chronic Heart Failure (MAGGIC-HF) risk score, which includes clinical variables + medications; Seattle Heart Failure Model (SHFM), which includes clinical variables + treatments + analytes; PARADIGM Risk of Events and Death in the Contemporary Treatment of Heart Failure (PREDICT-HF) and Barcelona Bio-Heart Failure (BCN-Bio-HF) risk calculator, which also include biomarke…
Laser Doppler Scanning: How Many Measurements are Required to Assess Regional Cerebral Blood Flow?
2000
This study was initiated to determine the optimal number of measuring sites necessary to estimate regional cerebral blood flow (CBF) under pathophysiological conditions.
Head–Neck Cancer Delineation
2021
Head–Neck Cancer (HNC) has a relevant impact on the oncology patient population and for this reason, the present review is dedicated to this type of neoplastic disease. In particular, a collection of methods aimed at tumor delineation is presented, because this is a fundamental task to perform efficient radiotherapy. Such a segmentation task is often performed on uni-modal data (usually Positron Emission Tomography (PET)) even though multi-modal images are preferred (PET-Computerized Tomography (CT)/PET-Magnetic Resonance (MR)). Datasets can be private or freely provided by online repositories on the web. The adopted techniques can belong to the well-known image processing/computer-vision a…
