Humour in EFL classrooms : a comparative case study between elementary and secondary school lessons
2014
Tämä laadullinen tapaustutkimus pyrkii selvittämään sekä opettaja- että oppilasaloitteisen huumorin roolia opetuksessa. Ilmiötä tarkastellaan eri huumorilajien kautta: ironia, kiusoittelu, leikinlasku, kielellä leikittely ja pilailu. Tutkimus on vertaileva, sillä tavoitteena on kuvailla oppilaiden luokka-asteen yhteyttä käytetyn huumorin määrään, huumorilajiin ja siihen onko huumori opettaja- vai oppilasaloitteista. Tämän lisäksi pohditaan huumorin positiivisia ja negatiivisia vaikutuksia luokan ilmapiiriin. Tarkoituksena ei ole yleistää vaan tutkia yksittäistä tapausta: miten kaksi luokkaa, yksi alakoulun ja yksi yläkoulun luokka, ja heidän yhteinen opettajansa käyttävät huumoria oppitunne…
Density Functional Theory Investigation on the Nucleation and Growth of Small Palladium Clusters on a Hyper-Cross-Linked Polystyrene Matrix
2014
Density functional theory calculations were employed to investigate the nucleation and growth of small palladium clusters, up to Pd9, into a microcavity of the porous hyper-cross-linked polystyrene (HPS). The geometries and the electronic structures of the palladium clusters inside the HPS cavity, following the one-by-one atom addition, are affected by a counterbalance between the Pd–phenyl (Pd−Φ) and Pd–Pd interactions. The analysis performed on energetics, cavity distortions, and cluster geometries indeed suggest that the cluster growth is dominated by the Pd−Φ interactions up to the formation of Pd4 aggregates, whereas the metal–metal interactions actually rule the growth of the larger c…

Information Decomposition in Bivariate Systems: Theory and Application to Cardiorespiratory Dynamics
2015
In the framework of information dynamics, the temporal evolution of coupled systems can be studied by decomposing the predictive information about an assigned target system into amounts quantifying the information stored inside the system and the information transferred to it. While information storage and transfer are computed through the known self-entropy (SE) and transfer entropy (TE), an alternative decomposition evidences the so-called cross entropy (CE) and conditional SE (cSE), quantifying the cross information and internal information of the target system, respectively. This study presents a thorough evaluation of SE, TE, CE and cSE as quantities related to the causal statistical s…
Transportan 10 Induces Perturbation and Pores Formation in Giant Plasma Membrane Vesicles Derived from Cancer Liver Cells
2023
Continuous progress has been made in the development of new molecules for therapeutic purposes. This is driven by the need to address several challenges such as molecular instability and biocompatibility, difficulties in crossing the plasma membrane, and the development of host resistance. In this context, cell-penetrating peptides (CPPs) constitute a promising tool for the development of new therapies due to their intrinsic ability to deliver therapeutic molecules to cells and tissues. These short peptides have gained increasing attention for applications in drug delivery as well as for their antimicrobial and anticancer activity but the general rules regulating the events involved in cell…
Computer Vision Interaction for People with Severe Movement Restrictions
2006
In this paper we present the starting point of research in applying humancomputer interaction (HCI) techniques to help people with cerebral palsy to use computers via vision-based interaction. Our work includes the development and improvement of visionbased assistive technology, which was tested in experiments with cerebral palsy users. A brief review of current assistive technologies for severely physically impaired people and an explanation of the developed applications of such technologies are also presented. The final part of the paper describes the experimentation goals, process, and preliminary results. Future work directions are also indicated.
Repression of Human Papillomavirus Oncogene Expression under Hypoxia Is Mediated by PI3K/mTORC2/AKT Signaling
2019
Oncogenic HPV types are major human carcinogens. Under hypoxia, HPV-positive cancer cells can repress the viral E6/E7 oncogenes and induce a reversible growth arrest. This response could contribute to therapy resistance, immune evasion, and tumor recurrence upon reoxygenation. Here, we uncover evidence that HPV oncogene repression is mediated by hypoxia-induced activation of canonical PI3K/mTORC2/AKT signaling. AKT-dependent downregulation of E6/E7 is only observed under hypoxia and occurs, at least in part, at the transcriptional level. Quantitative proteome analyses identify additional factors as candidates to be involved in AKT-dependent E6/E7 repression and/or hypoxic PI3K/mTORC2/AKT ac…
Definition of the chalcogen bond (IUPAC Recommendations 2019)
2019
Abstract This recommendation proposes a definition for the term “chalcogen bond”; it is recommended the term is used to designate the specific subset of inter- and intramolecular interactions formed by chalcogen atoms wherein the Group 16 element is the electrophilic site.
Tropical Temperate Toughs over southern Africa: mechanisms and evolution in response to climate change
2015
In the Southern Hemisphere, Southern Africa and the south-west Indian Ocean are one of the three preferred regions where interactions between the tropics and midlatitudes develop. This is the South Indian Convergence Zone (SICZ), where northwest-southeast oriented cloud bands form at the synoptic scale (between 3 and 5 days). These bands are mainly found during the austral summer and are commonly referred to as tropical temperate troughs (TTTs). This research aims at improving our knowledge related to TTTs, with a study on the dynamics associated with these systems, and an analysis of their possible evolution during the 21st century.The first part of this thesis aims at identifying favorab…
Dealing with interruptions in text-based chat sessions
2010
Running a teaching session that achieves its aims and objectives requires organised and structured dialogue between teacher and students that leaves room for a clear line of instructions. However, participants can disrupt the flow and prevent the achievement of these objectives through constant interruption (via questions or comments). The interruptions mentioned here include any discursive interaction that halts the flow of the argument and causes distraction for teacher and students.
