Variants in ZFHX3 are associated with atrial fibrillation in individuals of European ancestry

2009

We conducted meta-analyses of genome-wide association studies (GWAS) for atrial fibrillation (AF) in participants from five community-based cohorts. Meta-analyses of 896 prevalent (15,768 referents) and 2,517 incident (21,337 referents) AF cases identified a novel locus for AF (ZFHX3, rs2106261, risk ratio [RR]=1.19; P=2.3×10−7), an association that was replicated in the German AF Network (odds ratio=1.44; P=1.6×10−11). Combining the discovery and replication results, rs2106261 was significantly associated with AF (RR=1.25; P=1.8×10−15).

Evaluation of labor skills in Latvia

2019

Skills are a decisive factor for the country's economic development and social-well-being. The OECD emphasizes that strips can help countries integrate into global markets and specialize in technological advanced industries, and countries need to invest in fields not only to help people enter the labour market and protect from the risk of job losses and low quality of work, but also to increase international competitiveness and economic progress in an interlinked world. The aim of the research is to evaluate the most demanded labour skills in Latvia within the framework of certain groups of professions, as well as trends in the demand changes according to the skills of employees in order to…

Cognitive behavioural therapy interventions for insomnia among shift workers: RCT in an occupational health setting

2019

Abstract Introduction The aim of the study was to compare the effectiveness of cognitive behavioural therapy interventions for insomnia (CBT-I) to that of a sleep hygiene intervention in a randomized controlled design among shift workers. We also studied whether the features of shift work disorder (SWD) affected the results. Methods A total of 83 shift workers with insomnia disorder were partially randomized into a group-based CBT-I, self-help CBT-I, or sleep hygiene control intervention. The outcomes were assessed before and after the interventions and at 6-month follow-up using questionnaires, a sleep diary, and actigraphy. Results Perceived severity of insomnia, sleep-related dysfunction…

Variation of student engagement between different algebra tasks

2018

In this study, we analyse how 7th grade students’ engagement during small group work differed in two consecutive algebra lessons: in the first lesson students solved equa-tions and in the second lesson they created equations for other small groups to solve. Data was collected by videorecording the work of two groups in both lessons. Through directed content analysis, categories indicating student engagement were formed based on previous research and refined during analysis. The analysis revealed a change from individual engagement to collaborative engagement between lessons and an increase in many passive students’ engagement. Task characteristics which may affect the type and amount of eng…

Key challenges of new and small virtual team

2007

The purpose of this thesis is to study the factors must be noticed when building a new and small virtual team. These virtual teams are groups of people who work together without the boundaries of time or space using technology (Lipnack & Stamps 2000, 18). The main goal is to study in detail some of the common challenges faced when working with the small virtual teams, especially in the early stages of team development. With this study and the results of it, the reader is aware of the challenges of virtual teams and the differences and similarities between traditional and virtual teams. In addition the reader knows also some factors that must be noticed when a new small virtual team is suppo…

Facilitating leadership team communication

2015

The purpose of this study is to understand and describe how to facilitate competent communication in leadership teamwork. Grounded in the premises of social constructionism and informed by such theoretical frameworks as coordinated management of meaning theory (CMM), dialogic organization development (OD), systemic-constructionist leadership, communication competence, and reflexivity, this study seeks to produce further insights into understanding leadership team communication, communication competence, and team facilitation as applied communication research. This study consists of five articles. The first focuses on the theoretical framing of the relationality of communication competence i…

Addition of Ethylene or Hydrogen to a Main-Group Metal Cluster under Mild Conditions

2015

Reaction of the tin cluster Sn8(Arinline image)4 (Arinline image=C6H2-2,6-(C6H3-2,4,6-Me3)2) with excess ethylene or dihydrogen at 25 °C/1 atmosphere yielded two new clusters that incorporated ethylene or hydrogen. The reaction with ethylene yielded Sn4(Arinline image)4(C2H2)5 that contained five ethylene moieties bridging four aryl substituted tin atoms and one tin–tin bond. Reaction with H2 produced a cyclic tin species of formula (Sn(H)Arinline image)4, which could also be synthesized by the reaction of {(Arinline image)Sn(μ-Cl)}2 with DIBAL-H. These reactions represent the first instances of direct reactions of isolable main-group clusters with ethylene or hydrogen under mild conditions…

Low‐Valent Germanylidene Anions: Efficient Single‐Site Nucleophiles for Activation of Small Molecules

2021

Abstract Rare mononuclear and helical chain low‐valent germanylidene anions supported by cyclic (alkyl)(amino)carbene and hypermetallyl ligands were synthesised by stepwise reduction from corresponding germylene precursors via stable and isolable germanium radicals. The electronic structures of the anions can be described with ylidene and ylidone resonance forms with the Ge−C π‐electrons capable of binding even weak electrophiles. The germanylidene anions reacted with CO2 to give μ‐CO2‐κC:κO complexes, a rare coordination mode for low‐valent germanium and inaccessible for the related neutral germylones. These results implicate low‐valent germanylidene anions as efficient single‐site nucleop…
