Twin studies on the association of physical activity with cognitive and cerebral outcomes
2020
Regular physical activity (PA) offers positive effects on the human body. However, the effects of PA on cognition and in the brain are less clear. In this paper, we narratively review the relationship of PA with cognition and dementia, first from general perspective and then through genetically informed studies on the topic. Then we move on to imaging studies on exercise and brain anatomy first by presenting an overall picture of the topic and then discussing brain imaging studies addressing PA and brain structure in twins in more detailed way. Regarding PA and cognition or dementia, genetically informed studies are uncommon, even though the relationship between PA and cognitive ageing has …
Responsible cognitive digital clones as decision-makers: A design science research study
2022
This study uses a design science research methodology to develop and evaluate the Pi-Mind agent, an information technology artefact that acts as a responsible, resilient, ubiquitous cognitive clone – or a digital copy – and an autonomous representative of a human decision-maker. Pi-Mind agents can learn the decision-making capabilities of their “donors” in a specific training environment based on generative adversarial networks. A trained clone can be used by a decision-maker as an additional resource for one’s own cognitive enhancement, as an autonomous representative, or even as a replacement when appropriate. The assumption regarding this approach is as follows: when someone was forced t…
Concordant Intestinal Atresia in Two Pairs of Monozygotic Twins
2011
Intestinal atresia in both twins from the same pregnancy is very rare. Only seven pairs of twins have been described. The authors report on two cases of monozygotic twins with different types of intestinal atresia and clinical evolution. Both pairs of observed twins turned out to be concordant for the presence of intestinal malformations and for the absence of other linked malformations; nevertheless, the atresic lesions were anatomically discordant in each pair of monozygotic twins. Therefore, the diagnostic and therapeutic procedures have shown some differences in phenotypic expression between the twins of both pairs. Possible etiologic factors and pathogenetic pathways are discussed, and…
Diethyl [(2,5-diiodo-4-methylphenyl)methyl]phosphonate
2021
The title compound, C12H17I2O3P, was prepared in three steps from p-xylene. Heterodimers between nearly identical molecules are connected via three hydrogen bonds from benzylic and ester methylene groups to phosphonate. The dimers form chains along the a-axis direction, stabilized by C—H...O bridges.
Experiences of qualified teachers of the future in the scope of an international eTwinning project.
2022
The aim of robust social learning networks such as eTwinning, which is a part of Erasmus internationality programs, is to foster and promote the creation and development of awareness for respect, tolerance,and understanding by ensuring the integration of young people from different countries and cultures through dialogue. Phenomenological research design, one of the qualitative research methods, was used in this research in which the experiences of teacher candidates regarding the eTwinning project were analyzed. The focus of the transnational collaboration was that student teachers from different cultures use eTwinning’s secure and safe digital platform, Twinspace, to contribute to their c…
Innovating Initial Teacher Education: faculty members’ engagement in eTwinning
2023
The personal characteristics of teachers can be catalysts for their own and others’ learning, as much as their knowledge and competences. It explains why «the first and foremost resources teachers use are themselves» (Caena, 2014, p. 2). The selection, preparation and guidance of teachers throughout initial teacher education and the following stages of their careers are therefore crucial. This study involved faculty members teaching in Primary Education Degree Course at University of Palermo during the academic year 2021- 2022 and it aims at introducing and promoting eTwinning networking platform in higher education. It also aims at increasing the involvement of university teachers, PhD stu…
Empowering future teachers’ intercultural awareness with eTwinning
2022
This paper aims at examining the impact of eTwinning experience on empowering future teachers’ intercultural awareness within two different international eTwinning projects. The first project “What kind of World do we want?” has been given start in October 2021 and apart from University of Palermo it involves two different universities from Turkey. The second project “Qualified teacher of the future” has had its start in November with German, French and Turkish partner universities. The very first results underlines the importance of equipping students with twenty-first century skills and the important role eTwinning plays in this, as well as indicating main challenges which need to be addr…
Enhancing innovative pedagogical practices in Initial Teacher Education: eTwinning
2021
Non c'è dubbio che gli insegnanti di domani abbiano bisogno di una serie di competenze e caratteristiche per essere in grado di svolgere la loro professione in modo accurato. Gli ambienti di apprendimento online che si basano sull’uso delle tecnologie dell'informazione e della comunicazione (TIC) sono essenziali per promuovere l’acquisizione delle abilità del 21° secolo nei futuri insegnanti. All’interno degli ambienti di apprendimento on line, eTwinning, la piattaforma di networking per le scuole in Europa finanziata dalla Commissione europea può rappresentare un buon esempio di uso integrato delle TIC in campo educativo. Il contributo si propone di esaminare l'impatto dell'esperienza eTwi…
Aetiology for the covariation between combined type ADHD and reading difficulties in a family study: the role of IQ
2012
Background: Twin studies using both clinical and population-based samples suggest that the frequent co-occurrence of attention deficit hyperactivity disorder (ADHD) and reading ability/disability (RD) is largely driven by shared genetic influences. While both disorders are associated with lower IQ, recent twin data suggest that the shared genetic variability between reading difficulties and ADHD inattention symptoms is largely independent from genetic influences contributing to general cognitive ability. The current study aimed to extend the previous findings that were based on rating scale measures in a population sample by examining the generalisability of the findings to a clinical popul…
Genetic and environmental influences on non-specific neck pain in early adolescence: A classical twin study
2012
Background Prevalence of neck pain has increased among adolescents. The origins of adult chronic neck pain may lie in late childhood, but for early prevention, more information is needed about its aetiology. We investigated the relative roles of genetic and environmental factors in early adolescent neck pain with a classic twin study. Methods Frequency of neck pain was assessed with a validated pain questionnaire in a population-based sample of nearly 1800 pairs of 11–12-year-old Finnish twins. Twin pair similarity for neck pain was quantified by polychoric correlations, and variance components were estimated with biometric structural equation modelling. Results Prevalence of neck pain repo…
