Palladium-NHC (NHC = N-heterocyclic Carbene)-Catalyzed Suzuki–Miyaura Cross-Coupling of Alkyl Amides
2022
We report the Pd-catalyzed Suzuki–Miyaura cross-coupling of aliphatic amides. Although tremendous advances have been made in the cross-coupling of aromatic amides, C–C bond formation from aliphatic amides by selective N–C(O) cleavage has remained a major challenge. This longstanding problem in Pd catalysis has been addressed herein by a combination of (1) the discovery of N,N-pym/Boc amides as a class of readily accessible amide-based reagents for cross-coupling and (2) steric tuning of well-defined Pd(II)-NHC catalysts for cross-coupling. The methodology is effective for the cross-coupling of an array of 3°, 2°, and 1° aliphatic amide derivatives. The catalyst system is user-friendly, sinc…

Smadzeņu aktivitātes EEG novērtējums krustotās un nekrustotās disparitātes gadījumā
2022
Diplomdarbs ir uzrakstīts angļu valodā uz 25 lapaspusēm. Tas satur 14 attēlus, 1 tabulu un 67 literatūras avotus. Binokulārā disparitāte ir būtiska mūsu trīsdimensiju uztverei. Lielākajā daļā pētījumu tik izmeklēta smadzeņu darbības disparitāte apstrādes laikā, savukārt garozas aktivitātei katra veida atšķirības laikā tika pievērsta ļoti maza uzmanība. Pētījuma mērķis ir novērtēt smadzeņu aktivitāti krustotās un nekrustotās disparitātes anaglifēšanas vizualizācijas laikā uz plakanpaneļa displeja. Smadzeņu aktivitāte tika reģistrēta ar elektroencefalogrāfu, iegūtie potenciāli (ERP) un neirālās svārstības. Ievērojama aktivitāte tika izraisīta tikai P2 komponentē(ERP) attiecībā uz nesakrustotu…
Krustotās un nekrustotās stereoredzes izmaiņas pēc LASIK operācijas
2021
Maģistra darbs uzrakstīts angļu valodā uz 37 lappusēm. Tas satur 10 attēlus, 9 tabulas un darbam ir 49 atsauces uz literatūras avotiem. Pētījuma mērķis bija novērtēt krustotās un nekrustotās disparitātes stereoredzes asumu pirms redzes refraktīvās operācijas, divus, četrus un sešus mēnešus pēc operācijas. Pētījumā piedalījās 102 acu klīnikas pacienti – 65 sievietes un 37 vīrieši vecumā no 19 līdz 45 gadiem. Visiem bija miopija vai miopija ar astigmatismu. Jaunais izveidotais izkliedēto punktu globālais stereoredzes datorizētais tests dod iespēju novērtēt abus disparitātes veidus. Rezultātu analīzē tika secināts, ka nav novērojamas statistiski būtiskas izmaiņas stereoredzes asumā pirms un pē…
"Lempeä Lydia" - "voimakas Björgen" : naishiihtäjien representoinnin muutokset Urheilulehden teksteissä vuosina 1905-2010
2017
The purpose of my study is to examine how female skiers are represented in the texts of a Finnish sports magazine, Urheilulehti, and how these representations have changed during the examination period from 1905 to 2010. Relying on Judith Butler’s ideology of gender performativity, I analyse the representations of female skiers from the perspective of promoting the traditional female norm and simultaneously from the perspective of breaking and reforming it. The methodological framework of my study consists of Fairclough’s three- dimensional framework, which is based on the tradition of critical discourse analysis (CDA). In compliance with this framework, I began the analysis from the textua…
The effects on riding performance using active vs passive recovery during a simulated motocross race
2017
Aleix Ollé Casanovas. 2017. The effects on riding performance using active vs passive recovery during a simulated motocross race. University of Jyväskylä. 53p. The aim of the present study was to examine the effect of active and passive recovery methods in order to improve physical performance between motocross races. Exercise induced muscle damage post motocross racing was assessed as well. Participants performed 2 races of 30 minutes with one hour break in between. During the break they performed either active or passive recovery protocols. Specific motocross performance outcomes and athlete’s physical conditions were measured during, and before and after every motocross race. Lap times (…

Taking a Break from News : A Five-nation Study of News Avoidance in the Digital Era
2021
This article comparatively examines news avoidance in a rapidly changing media environment. We utilize findings from a large dataset of 488 in-depth interviews with media consumers, conducted in Argentina, Finland, Israel, Japan, and the US. We aim to make a contribution to the study of news avoidance by providing a comprehensive and nuanced understanding of the drivers, practices, and patterns of news avoidance as they occur in and are shaped by a variety of national contexts. We argue that news avoidance is shaped not only by individual characteristics, but is also manifested and performed as part of specific time frames and socio-cultural factors. We distinguish two drivers of intentiona…
An Updated Guideline for Assessing Discriminant Validity
2022
Discriminant validity was originally presented as a set of empirical criteria that can be assessed from multitrait-multimethod (MTMM) matrices. Because datasets used by applied researchers rarely lend themselves to MTMM analysis, the need to assess discriminant validity in empirical research has led to the introduction of numerous techniques, some of which have been introduced in an ad hoc manner and without rigorous methodological support. We review various definitions of and techniques for assessing discriminant validity and provide a generalized definition of discriminant validity based on the correlation between two measures after measurement error has been considered. We then review te…
Cross-cultural adaptation and validation of the Kerlan-Jobe Orthopaedic Clinic shoulder and elbow score in Finnish-speaking overhead athletes
2022
Background The Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow score (KJOC) is developed to evaluate the shoulder and elbow function in overhead athletes. To date, the score has not been adapted into Finnish language. The aim of this study was to perform a cross-cultural adaptation of the Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow score (KJOC) into Finnish language and evaluate its validity, reliability, and responsiveness in overhead athletes. Methods Forward–backward translation method was followed in the cross-cultural adaptation process. Subsequently, 114 overhead athletes (52 males, 62 females, mean age 18.1 ± 2.8 years) completed the Finnish version of KJOC score, Disabilitie…
