High Frequency Data Acquisition System for Modelling the Impact of Visitors on the Thermo-Hygrometric Conditions of Archaeological Sites: A Casa di D…

2018

[EN] The characterization of the microclimatic conditions is fundamental for the preventive conservation of archaeological sites. In this context, the identification of the factors that influence the thermo-hygrometric equilibrium is key to determine the causes of cultural heritage deterioration. In this work, a characterization of the thermo-hygrometric conditions of Casa di Diana (Ostia Antica, Italy) is carried out analyzing the data of temperature and relative humidity recorded by a system of sensors with high monitoring frequency. Sensors are installed in parallel, calibrated and synchronized with a microcontroller. A data set of 793,620 data, arranged in a matrix with 66,135 rows and …

Thermal and thermo-oxidative stability and kinetics of decomposition of PHBV/sisal composites

2017

The decomposition behaviours of composites made of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and sisal were assessed in terms of thermal stability and decomposition kinetics, under inert and oxidative conditions, by means of multi-rate linear non-isothermal thermogravimetric experiments. A statistical design of experiments was applied to study the influence of the addition of sisal (0-10-20-30%wt), the presence coupling agent (Yes/No) and the applied conditions of work (inert or oxidative). An improvement of the thermal and thermo-oxidative stability of PHBV with the addition of sisal was observed for all cases. An accurate methodology based on iso-conversional methods was applied…

Students’ evaluation of information during online inquiry: Working individually or in pairs

2019

Varying information quality and an increase of misinformation on the Internet accentuates the importance of supporting students’ competencies to critically evaluate information. This study compared how individuals and pairs of secondary students worked to evaluate the quality of online information across two inquiry topics. Two similar studies were conducted with 140 Finnish (Study I) and 52 US (Study II) students. Students were asked to conduct an online inquiry and then write an essay about one of two topics: allowing the genetic modification of organisms (GMO) or the effects of social media on people’s quality of life (SM). Students worked either individually or in pairs. Their work was …

Translation and dealing with “the other” in scholarly research and publishing:

2022

Although languages other than English, along with various forms of translation, are intrinsic to multilingual researchers’ scholarly activities, they generally remain less visible in English-medium publications. In this discussion paper, I explore this topic from a broader sociopolitical perspective by looking at the use and function of translation in various stages of research and writing for publication. Drawing on recent studies on multilingualism in academia and my own experience as a teacher of research communication, I argue that in the academic context, translation cannot be seen as a mere linguistic act or a communication tool as it is inextricably tied to complex and multilayered c…

Applying video games in language learning and teaching : the learner perspective: a case study

2012

Tutkielman tarkoituksena on selvittää oppijoiden näkemyksiä videopelien nykyisistä ja mahdollisista käyttötavoista kieltenopetuksessa ottaen huomioon koehenkilöiden koulutus- ja pelaajataustan. Pelitutkimusta ei ole vielä tehty kauaa, joten ala on hajanainen, mutta tämä tutkimus pohjautuu tietokoneavusteisen oppimisen (CALL) ja videopeleihin perustuvan oppimisen (DGBL) tutkimukseen. CALL ei keskity erikseen pelien käyttöön tai käsittelee enemmän kieltenoppimiseen tehtyjä ohjelmia, kun taas peleihin perustuvassa opetuksessa kielet eivät ole erityisasemassa. Oppimistuloksia ja oppijakokemuksia pelien käytöstä on kerätty lähinnä esikoulu- ja peruskouluikäisiltä, joten lukiolaiskokeilu täydentä…

A Study on the Assessment of Introductory Computational Thinking via Scratch Programming in Primary Schools

2018

Computational thinking (CT), a transversal intellectual foundation integral to computer science, is making its way into compulsory comprehensive education worldwide. Students are expected to attain skills and knowledge in such interdisciplinary CT principles as Algorithmic thinking, Data representation, and Debugging. Problem-solving by designing and manipulating interactive media with Scratch, a graphical programming tool, is popular especially at the primary school level. However, there has been confusion regarding how introductory CT can be operationalized for educational practice. Teachers and students need research-based knowledge for setting appropriate learning goals in addition to i…

Arithmetic, Logic, Syntax and MathCheck

2019

MathCheck is a web-based tool for checking all steps of solutions to mathematics, logic and theoretical computer science problems, instead of checking just the final answers. It can currently deal with seven problem types related to arithmetic, logic, and syntax. Although MathCheck does have some ability to perform symbolic computation, checking is mostly based on testing with many combinations of the values of the variables in question. This introduces a small risk of failure of detection of errors, but also significantly widens the scope of problems that can be dealt with and facilitates providing a concrete counter-example when the student’s solution is incorrect. So MathCheck is primari…

Time-like Proton Form Factors with Initial State Radiation Technique

2022

Electromagnetic form factors are fundamental quantities describing the internal structure of hadrons. They can be measured with scattering processes in the space-like region and annihilation processes in the time-like region. The two regions are connected by crossing symmetry. The measurements of the proton electromagnetic form factors in the time-like region using the initial state radiation technique are reviewed. Recent experimental studies have shown that initial state radiation processes at high luminosity electron-positron colliders can be effectively used to probe the electromagnetic structure of hadrons. The BABAR experiment at the B-factory PEP-II in Stanford and the BESIII experim…
