2022
Kvalifikācijas darba tēma- Mūzika, kā palīgrīks bērnu snieguma uzlabošanai futbolā. Darba mērķis- noskaidrot, kā mūzika ietekmē bērnu sniegumu un cik ļoti mūzika, kā palīgrīks var būt noderīgs trenerim, lai uzlabotu bērnu sniegumu futbolā. Darbs sastāv no ievada, teorētiskās daļas, praktiski pētnieciskās daļas, rezultātu analīzes un secinājumiem. Teorētiskajā daļā tiek aprakstīta mūzikas vēsture un tās pamatprincipi, mūzikas ietekme uz cilvēku, audiālā sistēma, sniegums, vecuma īpatnības. Praktiski pētnieciskajā daļā iesaistītas 2 grupas- 10 gadus jauni futbolisti un 9 gadus jauna, vispārējās fiziskās attīstības grupa. Ar anketēšanas palīdzību tika noteikts treniņu stāžs futbolā/sportā, mūz…
A scalable school‐based intervention to increase early adolescents' motor competence and health‐related fitness
2023
Schools are key settings for the promotion of students' physical activity, fitness, and motor competence. The purpose of our study was to investigate the efficacy of a 5-month-long intervention program that aimed to increase students' motor competence and health-related fitness during school days. We conducted a quasi-experimental study with 325 Finnish Grade 5 (Mage = 11.26, SD = 0.33) students from five schools. Two schools were allocated to the intervention group and three schools to the control group. The intervention consisted of three components: (a) weekly 20 min session during regular PE lessons, (b) weekly 20 min session during recess, and (c) daily 5-minute-long classroom activity…
Iedzīvotāju gatavība un prasmes sniegt pirmo palīdzību veselībai kritiskās situācijā
2021
Bakalaura darba tēma: „Iedzīvotāju gatavība un prasmes sniegt pirmo palīdzību veselībai kritiskās situācijās.” Tēmas aktualitāti pamato/nosaka: Neraugoties uz to, ka prasmei sniegt pirmo palīdzību vajadzētu būt katra cilvēka interesēs, prakse rāda, ka iedzīvotāju gatavība sniegt palīdzību un zināšanas šajā jomā, ir vērtējamas kā nepietiekamas. Tomēr tiek uzskatīts, ka daļu traumu izraisītu nāves gadījumu varētu novērst, veicot pamata pirmās palīdzības pasākumus notikuma vietā. Pētījuma mērķis: noskaidrot iedzīvotāju viedokli par viņu prasmi un gatavību sniegt pirmo palīdzību veselībai kritiskās situācijās. Pētījuma hipotēze – iedzīvotāji ir gatavi sniegt pirmo palīdzību veselībai kritiskās …
Self in NARS, an AGI System
2018
This article describes and discusses the self-related mechanisms of a general-purpose intelligent system, NARS. This system is designed to be adaptive and to work with insufficient knowledge and resources. The system’s various cognitive functions are uniformly carried out by a central reasoning-learning process following a “non-axiomatic” logic. This logic captures the regularities of human empirical reasoning, where all beliefs are revisable according to evidence, and the meaning of concepts are grounded in the system’s experience. NARS perceives its internal environment basically in the same way as how it perceives its external environment although the sensors involved are completely diff…
Le repérage des patients en situation de précarité par les médecins généralistes
2019
Cette étude se propose d’étudier la concordance entre un repérage de la précarité effectué spontanément par les médecins généralistes et un repérage effectué par le score EPICES (évaluation de la précarité et des inégalités de santé dans les centres d’examens de santé), développé et validé dans les centres d’examens de santé.Les 32 médecins généralistes ont permis d’inclure 207 patients dans l’étude. Le coefficient de concordance Kappa de Cohen était de 0,404, soit une corrélation faible à modérée.L’étude des variables associées à la concordance de ce repérage n’a permis de dégager aucune variable significativement associée à la concordance après une analyse multivariée.Pour conclure, le re…
Stepping up to genome scan allows stock differentiation in the worldwide distributed blue shark Prionace glauca
2023
The blue shark Prionace glauca is a top predator with one of the widest geographic distributions of any shark species, yet classified as critically endangered in the Mediterranean Sea, and Near Threatened globally. Previous genetic studies did not reject the null hypothesis of a single global population across the worldwide species range. Blue shark situation was proposed as a possible archetype of the ‘grey zone of population differentiation’, coined to designate cases where population structure may be too recent or too faint to be detected using a limited set of markers. Here, blue shark samples collected throughout its global range were sequenced using a specific ddRAD method (DArTseq; G…
Exploring land snails’ response to habitat characteristics and their potential as bioindicators of riparian forest quality
2021
Abstract Riparian ecosystems are crucial for landscape-level biodiversity, especially in highly anthropic and agricultural areas. Although the low mobility of snails reduces their dispersal capacity and makes them vulnerable to habitat degradation, they are less commonly used as indicators. We evaluated the potential of land snails as bioindicators of riparian forest quality in central European riparian forests by surveying snail communities in relation to habitat characteristics that characterize its quality. Habitat characteristics were found to affect both snail abundance and species richness. The abundance of snail species increased with the forest continuity, forest width and abundance…
Recent Change—River Run-off and Ice Cover
2015
This chapter compiles and assesses information on run-off and discharge from rivers within the Baltic Sea drainage basin. Some information is also available on ice duration on inland waterways. Although decadal and regional variability is large, no significant long-term change has been detected in total river run-off to the Baltic Sea over the past 500 years. A change in the timing of the spring flood has been observed due to changes in the timing of snowmelt . Change in temperature seems to explain change in run-off better than does precipitation. Later start dates for ice formation on waterways, and earlier ice break-up dates have resulted in shorter periods of ice cover.
Wintertime Airborne Measurements of Ice Nucleating Particles in the High Arctic: A Hint to a Marine, Biogenic Source for Ice Nucleating Particles
2020
Ice nucleating particles (INPs) affect the radiative properties of cold clouds. Knowledge concerning their concentration above ground level and their potential sources is scarce. Here we present the first highly temperature resolved ice nucleation spectra of airborne samples from an aircraft campaign during late winter in 2018. Most INP spectra featured low concentration levels (<3 · 10−4 L−1 at −15°C). −2 −1 However, we also found INP concentrations of up to 1.8·10 L at −15°C and freezing onsets as high as −7.5°C for samples mainly from the marine boundary layer. Shape and onset temperature of the ice nucleation spectra of those samples as well as heat sensitivity hint at biogenic INP. Col…
A mechanism for brief glacial episodes in the Mesozoic greenhouse
2011
[1] The Mesozoic, perhaps the longest period of warmth during the Phanerozoic Earth history, has been repeatedly affected by short-lived cold interludes lasting about one million years. While the origin of these cold snaps has been classically attributed to a temporary atmospheric CO2 drawdown, quantified mechanisms explaining these instabilities of the carbon cycle are still lacking. Based on a climate carbon cycle model, we show that the general demise of carbonate platforms accompanying these short-lived cold interludes is a powerful mechanism capable of generating a fast atmospheric CO2 decrease and a moderate sea level drop associated with ice sheet buildup. The temporary nature of the…
