On presentations for mapping class groups of orientable surfaces via Poincaré's Polyhedron theorem and graphs of groups

2021

The mapping class group of an orientable surface with one boundary component, S, is isomorphic to a subgroup of the automorphism group of the fundamental group of S. We call these subgroups algebraic mapping class groups. An algebraic mapping class group acts on a space called ordered Auter space. We apply Poincaré's Polyhedron theorem to this action. We describe a decomposition of ordered Auter space. From these results, we deduce that the algebraic mapping class group of S is a quotient of the fundamental group of a graph of groups with, at most, two vertices and, at most, six edges. Vertex and edge groups of our graph of groups are mapping class groups of orientable surfaces with one, tw…

Automorphisms of 2–dimensional right-angled Artin groups

2007

We study the outer automorphism group of a right-angled Artin group AA in the case where the defining graph A is connected and triangle-free. We give an algebraic description of Out.AA/ in terms of maximal join subgraphs in A and prove that the Tits’ alternative holds for Out.AA/. We construct an analogue of outer space for Out.AA/ and prove that it is finite dimensional, contractible, and has a proper action of Out.AA/. We show that Out.AA/ has finite virtual cohomological dimension, give upper and lower bounds on this dimension and construct a spine for outer space realizing the most general upper bound. 20F36; 20F65, 20F28

The influence of serotonin- and other genes on impulsive behavioral aggression and cognitive impulsivity in children with attention-deficit/hyperacti…

2008

Contains fulltext : 70708.pdf (Publisher’s version ) (Open Access) ABSTRACT: BACKGROUND: Low serotonergic (5-HT) activity correlates with increased impulsive-aggressive behavior, while the opposite association may apply to cognitive impulsiveness. Both types of impulsivity are associated with attention-deficit/hyperactivity disorder (ADHD), and genes of functional significance for the 5-HT system are implicated in this disorder. Here we demonstrate the separation of aggressive and cognitive components of impulsivity from symptom ratings and test their association with 5-HT and functionally related genes using a family-based association test (FBAT-PC). METHODS: Our sample consisted of 1180 o…

Teacher Training for Children with Autism Spectrum Disorders in Finland

2019

This chapter first provides a short description of the historical background and development of special education teacher training in Finland. The relationship between special education and teaching pupils with autism spectrum disorder (ASD) is covered by chronologically presenting the main events, turning points, publications, and people that have had a significant effect on the education of pupils with ASD in Finland. This is followed by a description of the organization of teacher training, in general, and the particular characteristics of teaching pupils with ASD. In the context of ASD, it is essential to examine questions concerning the link between learning as social practice and the …

Thermomineral waters of Greece: geochemical characterization

Regarding TDS concentrations collected waters can be subdivided into low salinity (up to 1.5 g/L) brackish (up to 20 g/L) and saline (up to 43 g/L). The medium high salinities can be justified by mixing with sea water and/or strong waterrock interaction processes. Isotope composition of O and H ranges from 12.7 to +2.7 ‰ SMOW and from 91 to +12 ‰ SMOW respectively and is generally comprised between the Global Meteoric Water Line and the East Mediterranean Meteoric Water Line. Only few water samples show a positive shift for δ18O possibly related to high temperature waterrock interaction processes.

Moreover the majority of them is found along the coast as well as in islands of the Aegean Sea and thus thermal water is often brackish to saline due to marine intrusion into costal aquifer. In the present study almost 300 thermal and cold mineral water samples were collected along the Hellenic territory with their physicochemical parameters (temperature pH electrical conductivity and Eh) and the amount of bicarbonates (titration with 0.1N HCl) being determined in situ. Additionally gases found either in free or dissolved phase were sampled. Both water and gas samples were analysed at the INGVPa laboratories for major ions (Ion Chromatography) silica (Inductively Coupled Plasma Optical Emission Spectrometry) chemical composition of free and dissolved gases (Gas Chromatography) water isotopes (O and H) and carbon and helium isotopes of free and dissolved gases (Mass Spectrometry). The temperature of the investigated waters ranges from 6.5 to 98°C pH from 1.96 to 11.98 whilst Total Dissolved Solids (TDS) from 0.06 to 43 g/L. Based on the temperature parameter waters can be divided into four groups: i) cold (&lt0.5 913000 μmol/mol) are the prevailing gas species found in the studied sites.

¿El Estado de Derecho en peligro? El juez constitucional contra la Constitución y a favor de la reelección presidencial indefinida : caso Bolivia

2021

In Bolivia, the third term and the habilitation of former President Evo Morales to the 2019 presidential elections was allowed with the acquiescence of the Plurinational Constitutional Court. Despite the fact that the Constitution prohibited it and there was a referendum that rejected indefinite presidential re-election. This occurred through the judicialization of politics that produced a non-formal reform of the Constitution producing a case of abusive constitutionalism and the destabilization of the rule of law.

Mindful Tourism Services for People with Mental Impairment. Situation Scan: Latvia, 2021

2021

The report is part of the EU Erasmus + funded project “Mindful tourism services for mentally disordered people” (MindTour). The project aims to promote and support tourism entrepreneurs to value mentally disordered clients and their families as persons and customers and help them design mindful tourism services accessible for mentally disordered people. The project is implemented in cooperation with Estonian, Belgian and Latvian higher education institutions – University of Tartu, Pärnu College (Estonia), Thomas More Mechelen-Antwerpen (Belgium), University of Latvia (Latvia), as well as leisure and tourism service providers - Pärnu Museum (Estonia), Museum Dr Guislain (Belgium) and SIA Zei…

The role of customer online reviews in the discourse-dialogic construction of hotel websites

2015

Esta comunicación da cuenta de una investigación que intenta desvelar si las webs hoteleras incluyen una comunicación hotel-cliente (autor-lector), partiendo de las reseñas de los viajeros y transformando estas críticas en estrategias discursivas para implicar al cliente. Para ello, se han analizado las reseñas de cuatro hoteles, de forma cuantitativa y cualitativa. Los resultados muestran así un mejor conocimiento del rol de las reseñas en línea en la construcción discursiva de las webs hoteleras. This research attempts to assess whether hotel websites include writer-reader interplay using stance markers from customer reviews and transforming them into engagement strategies, which are nece…

Subgroups of Children with Autism Spectrum Disorder without Intellectual Disability: A Longitudinal Examination of Executive and Socio-Adaptive Behav…

2021

Within the autistic spectrum, there is remarkable variability in the etiology, presentation, and treatment response. This prospective study was designed to identify, through cluster analysis, subgroups of individuals with ASD without intellectual disability (ID) based on the severity of the core symptoms in childhood. The secondary aim was to explore whether these subgroups and a group with typical development (TD) differ in cognitive, adaptive, and social aspects measured in adolescence. The sample at baseline was comprised of 52 children with ASD without ID and 37 children with TD, aged 7–11. Among the ASD group, three clusters were identified. Cluster 1 (40%), ‘high severity’, presented …
