Dynamic Functional Connectivity in the Musical Brain
2019
Musical training causes structural and functional changes in the brain due to its sensory-motor demands. This leads to differences in how musicians perceive and process music as compared to non-musicians, thereby providing insights into brain adaptations and plasticity. Correlational studies and network analysis investigations have indicated the presence of large-scale brain networks involved in the processing of music and have highlighted differences between musicians and non-musicians. However, studies on functional connectivity in the brain during music listening tasks have thus far focused solely on static network analysis. Dynamic Functional Connectivity (DFC) studies have lately been …
Women fighters as agents of change: A Brazilian jiu jitsu case study from Finland
2015
Brazilian jiu jitsu (BJJ), a grappling system of combat, evolved from the teachings of a Japanese judoka who moved to Brazil in the 1920s. Focusing on ground fighting, BJJ is rapidly evolving into a combat sport with competitions taking place worldwide (Hogeveen and Hardes, 2014; Spencer, 2014). Unique to the BJJ culture is the way that the ‘secrets’ of the sport are transferred from expert to novice and from one club to the other. Clubs are organised into international ‘teams’, shaping global communities of practitioners that share techniques and philosophies. Unlike many other martial arts that insist on the traditional way of passing knowledge from one teacher to many students behind the…
Accessibility and participation in Tanzanian higher education from the perspectives of women with disabilities
2016
This study investigated how women with disabilities participate in higher education and what enables them to succeed in their studies. The Social Model of Disability (SMD) guided the study because it emphasises the removal of barriers which continue to exclude and marginalize women with disabilities from social, cultural and economic opportunities, including education. To support the model, this study was conducted at the University of Dar es Salaam (UDSM) in Tanzania to establish the challenges and opportunities that facilitated the women with disabilities to enrol at the university. The study involved 22 women with disabilities who managed to enrol at the UDSM, regardless of their types o…

Sisters of the Brotherhood: Alienation and Inclusion in Learning Philosophy
2023
This open access book explores the gendered reality of learning philosophy at the university level, investigating the ways in which women and minority students become alienated from the social practices of a male-dominated field, and examining pedagogical solutions to this problem. It covers the roles and the interactions of the professor and student in the following ways: (1) the historical situation, (2) the affective, social and bodily situation, and (3) the moral situation. This text analyzes women’s passion for philosophy as a quest for truth, as well as their partial alienation from the social practices of philosophy. It demonstrates that recognition, generosity, and care are central …
From Symmetry Breaking to Unraveling the Origin of the Chirality of Ligated Au13Cu2 Nanoclusters
2018
A general method, using mixed ligands (here diphosphines and thiolates) is devised to turn an achiral metal cluster, Au13Cu2, into an enantiomeric pair by breaking (lowering) the overall molecular symmetry with the ligands. Using an achiral diphosphine, a racemic [Au13Cu2(DPPP)3(SPy)6]+ was prepared which crystallizes in centrosymmetric space groups. Using chiral diphosphines, enantioselective synthesis of an optically pure, enantiomeric pair of [Au13Cu2((2r,4r)/(2s,4s)‐BDPP)3(SPy)6]+ was achieved in one pot. Their circular dichroism (CD) spectra give perfect mirror images in the range of 250–500 nm with maximum anisotropy factors of 1.2×10−3. DFT calculations provided good correlations wit…
The Role of Donor and Acceptor Substituents on the Nonlinear Optical Properties of Gold Nanoclusters
2018
In recent years, a large number of monolayer-protected clusters (MPCs) have been studied by means of single crystal structure characterization. A central aspect of research on MPCs is the correlation of their interesting optical properties with structural features and the formulation of a theoretical framework that allows interpretation of their unique properties. For this, superatom and jellium models have been proven successful. Little attention, however, has been paid to the influence of the protecting ligands. Here, we investigate the effect of changes in [Au25(SR)18-x(SR′)x]−, where SR′ represents a para-substituted thiophenolate derivative (SPh-4-X). We computed the first hyperpolariz…
Robust, Highly Luminescent Au13 Superatoms Protected by N-Heterocyclic Carbenes
2019
Gold superatom nanoclusters stabilized entirely by N-heterocyclic carbenes (NHCs) are reported. The reduction of well-defined NHC–Au–Cl complexes produces clusters com-prised of an icosahedral Au13 core surrounded by a symmetrical arrangement of 9 NHCs and 3 chlorides. X-ray crystallography shows that the clusters are characterized by multiple CH–π and π–π interactions, which rigidify the ligand and likely con-tribute to the exceptionally high photoluminescent quantum yields observed, up to 16.0 %, which is significantly greater than the most luminescent ligand-protected Au13 superatom cluster. Density functional theory analysis suggests that clus-ters are 8-electron superatoms with a wide …
Cd12Ag32(SePh)36 : Non-Noble Metal Doped Silver Nanoclusters
2019
While there are numerous recent reports on doping of a ligand-protected noble metal nanocluster (e.g., Au and Ag) with another noble metal, non-noble metal (e.g., Cd) doping remains challenging. Here, we design a phosphine-assisted synthetic strategy and synthesize a Cd doped Ag nanocluster, Cd12Ag32(SePh)36 (SePh: selenophenolate), which exhibits characteristic UV–vis absorption features and rare near-infrared (NIR) photoluminescence at ∼1020 nm. The X-ray single crystal structure reveals an asymmetric two-shell Ag4@Ag24 metal kernel protected by four nonplanar Cd3Ag(SePh)9 metal–ligand frameworks. Furthermore, the electronic structure analysis shows that the cluster is a 20-electron “supe…
Narratives of children with high-functioning autism spectrum disorder: A meta-analysis
2016
Abstract Background The aim of this meta-analysis was to analyze the narrative performance of children and adolescents with high-functioning Autism Spectrum Disorders (ASD) in terms of microstructure, macrostructure and internal state language. Method A systematic literature search yielded 24 studies that met the predetermined inclusion criteria. Effect sizes for each study were calculated for eight variables and analyzed using a random effects model. Intellectual ability, age and type of narrative were considered as potential moderators. Results Results revealed that the children with ASD performed significantly worse than their peers on all the variables considered. Conclusions Findings a…
