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…

Possibilities for Intervention in Domestic Violence: Frame Analysis of Health Care Professionals’ Attitudes

2014

ABSTRACT. Violence is a serious problem, and social and health care providers are in a key position for implementing successful interventions. This qualitative study of 6 focus groups with professionals (n = 30) examines the health care professionals’ ways of framing a domestic violence intervention. Of special interest here is how professionals see their own roles in the process of recognizing and helping victims of domestic violence. By using Erving Goffman's frame analysis, this study identifies several frames that either: a) emphasize the obstacles to intervention and justify nonintervention, or on the contrary, b) question these obstacles and find justifications for intervention. The p…

Populārās Latvijas personas Instagram vietnē kā viedokļa līderi kosmētikas un modes preču segmentā Latvijas patērētāju starpā 2016.-2017. gadā

2018

Maģistra darba mērķis ir izpētīt sociālajā tīklā Instagram populāro Latvijas iedzīvotāju auditorijas izcelsmi un aktivitāti; noteikt, vai sociālajā tīklā Instagram Latvijas ietekmētāji ir bijuši viedokļu līderi Latvijas iedzīvotājiem vecumā no 18 līdz 35 gadiem modes preču segmentā 2016.-2017.gadā; noteikt faktorus, kas ļauj identificēt un izvērtēt sociālo tīklu ietekmētājus kosmētikas līdzekļu un apģērbu jautājumos. Darbā aplūkotās tādas tēmas kā patēriņa kultūra, demonstratīvs patēriņš, etalongrupas, viedokļu līderi, komunikācija no mutes mutē, sociālo tīklu ietekmētāji un to atlases un novērtēšanas paņēmieni. Tika izmantotas trīs pētījuma metodes – kontentanalīze, daļēji strukturētās int…

Open Dialogues in social networks: professional identity and transdisciplinary collaboration

2010

Aim: The aim of this article is to explore the challenges connected to the transformation and emergence of professional identity in transdisciplinary multi-agency network meetings and the use of Open Dialogue.Introduction: The empirical findings have been taken from a clinical project in southern Norway concerning multi-agency network meetings with persons between 14 and 25 years of age. The project explores how these meetings are perceived by professionals working in various sectors.Methodology: Data was collected through three interviews conducted with two focus groups, the first comprising health care professionals and the second professionals from the social and educational sectors.

Espace culturel, territoire et terroir : approches spatiales des groupes campaniformes récents dans le sud-est de la France

2000

In south-eastern France, the récent Bell-Beaker culture is marked by the presence of a regional Rhône-Provence group having complex relationships with other régional Bell-Beaker and regional final Neolithic groups. The analysis from a spatial point of view and at different levels (cultural space, territory, land) leads to a better knowledge of prehistoric geography and also to raises other questions, such as chronology, history of populations and socio-economic models.
