K-theory for Cuntz-Krieger algebras arising from real quadratic maps

We compute the $K$-groups for the Cuntz-Krieger algebras $\mathcal{O}_{A_{\mathcal{K}(f_{\mu})}}$, where $A_{\mathcal{K}(f_{\mu})}$ is the Markov transition matrix arising from the \textit{kneading sequence }$\mathcal{K} (f_{\mu})$ of the one-parameter family of real quadratic maps $f_{\mu}$.Comment: 8 page

Bowen–Franks groups of reducible bimodal subshifts of finite type

AbstractWe study the Bowen–Franks groups of subshifts of finite type associated with reducible bimodal periodic kneading sequences pairs

Assessing obstetrics perceived service quality at a public hospital

Assessing service quality has become a major issue in the healthcare sector. Although direct evaluation has already taken place, literature is scarce in terms of the impact the distance covered by the user has on perceived service quality. The aim of this study was to assess the influence distance has on perceived service quality when no similar service alternatives are available. The Servperf instrument was used to collect data. All women who delivered babies in autumn 2011 were respondents to the questionnaire. Exploratory analysis was used to test research hypotheses. Cronbach’s alphas were computed to assess internal consistency. Findings show that Assurance is the quality dimension that contributes the most to patients’ perceived service quality and Tangibles is the one that contributes the least. It was also possible to conclude that the distance the patient has to cover to be served and its educational level influence patients’ perception of the service providedinfo:eu-repo/semantics/publishedVersio

Classroom teachers’ perception about physical education and physical activity: A typology

Introduction: According to the socioecological model teachers may act as facilitators or barriers in a school physical activity (PA) program. Objectives: The purpose of this study was to characterize classroom teachers’ perceptions about Physical Education (PE). Methods: 297 teachers answered a questionnaire about PE past experience, status, aims, and academic benefits of PA. The Multiple Correspondence Analysis was used aiming to identify teachers’ profiles. Results: Dimension 1 combines the view that the PA affects academic achievement (AA) with the idea that PE must be optional or compulsory, but non-examinable. In dimension 2 the biggest difference is between a standard that refers to a relatively neutral position in relation to PA (PE as important for promotion of healthy lifestyles associated with the idea that PA does not affect AA, and PE should be compulsory but non-examinable), as opposed to positions, either in favour (PA benefits AA and PE should be compulsory and examinable) or against PA (PE should be optional). The joint analysis of the two dimensions allowed to identify three distinct patterns of teacher’s perceptions which made possible to build a typology, regardless the cluster they belong to. Considering their personal experience teachers make a misjudgment of PE in schools they attended specially in cluster 3. As for the relation between PA and AA, most teachers say that the PA benefits AA (65% in cluster 1; 96% in cluster 2). In cluster 3, 70% of the teachers say that PA impairs AA. Conclusions: These results support the importance of the earliest good experiences in PE, in generating positive attitudes towards PE. PE teachers should explain to other teachers that PA does not affect academic performance, and that PA prevents deviant behaviours.info:eu-repo/semantics/publishedVersio

Níveis de atividade física de adolescentes portugueses no primeiro período de confinamento devido à pandemia de COVID-19 e as primeiras atividades de professores e treinadores: Um estudo transversal

Due to the COVID-19 pandemic, social confinement was declared in Portugal on 19th March 2020. Schools and sports clubs were closed, access to all sports and leisure facilities was limited, and young people have experienced restrictions regarding the practice of physical activities and sports. The purpose of this study was to identify the physical activity (PA) levels and sports participation of adolescents before and during confinement, with whom they practice during restrictions and to identify the activities adopted by their physical education (PE) teachers and sports coaches to keep them physically active. An online survey was conducted between March 27th and April 14th 2020. A total of 3,012 Portuguese adolescents (57% females) aged between 10 and 19 years old (14.3±2.4 years old) took part in this study. Wilcoxon test and paired-sample t-test and chi-square test of independence were used in the data analysis. The results show that the number of students engaged in PA increased during the lockdown (72.7% to 88.2%). For those who practiced PA before lockdown, the frequency of PA decreased from 4.7 sessions/week to 4.4 sessions/week (during confinement). For those who did not practice PA before confinement, they started by doing 4.1 sessions/week. The vast majority of PE teachers (77.3%) proposed some pedagogical activities such as video conference classes (53.6%). Regarding the coaches, 53.4% proposed some activity, mainly time circuit training, walking and cycling (around 18% each), or specific training exercises and video conference classes (about 12% each). The number of students who increased their regular PA practice can be justified by the immediate intervention of PE teachers, who implemented several online activities, or because students were able to choose different options to stay active.info:eu-repo/semantics/publishedVersio
