International Assessment Surveys of Educational Achievement in Developing Countries : Why Education Economists Should Care
2015
International audience; This paper reviews the most known international assessment studies that are conducted in the context of poor countries and highlights the lack of empirical evidence on the degree to which the contents of the tests really match countries' curricula. To illustrate, the paper evaluates the sensitivity of an international testing instrument by comparing the responses of students in two consecutive grades on the same battery of tests. Using propensity score matching to control for student and teacher characteristics, the results show that the tests are not grade sensitive, which raises the question of the validity of many empirical works that are based on similar instrume…
Methodological Guidelines Designed to Improve the Quality of Research on Cross-Country Skiing
2021
AbstractCross-country (XC) ski races involve a variety of formats, two different techniques and tracks with highly variable topography and environmental conditions. In addition, XC skiing is a major component of both Nordic combined and biathlon competitions. Research in this area, both in the laboratory and field, encounters certain difficulties that may reduce the reliability and validity of the data obtained, as well as complicate comparisons between studies. Here, 13 international experts propose specific guidelines designed to enhance the quality of research and publications on XC skiing, as well as on the biathlon and Nordic combined skiing. We consider biomechanical (kinematic, kinet…
Choosing to listen : how personality is connected to the listening and use of self-chosen music in everyday life
2013
Tämän tutkimuksen tavoitteena oli selvittää, voiko persoonallisuudella olla jonkinlainen yhteys arkipäivässä valitsemamme musiikin kuunteluun ja käyttötarkoituksiin. Tutkimusmateriaali koostui aiemmin toteutetusta, struksturoidulla online-kyselyllä kerätystä materiaalista, jossa itse data-analyysiin kelpuutettuja vastaajia oli 340. Vastanneet koostuivat Jyväskylän yliopiston Humanistisen tiedekunnan opiskelijoista. Online-kysely koostui useasta osasta: Persoonallisuustestistä (BFI; John & Srivastava, 1999), sekä osioista, joissa käsiteltiin musiikin kuunteluun liittyviä funktioita ja tilanteita. Lisäksi selvitettiin vastanneiden musiikillista kokemusta ja musiikin viikkokuuntelumääriä. Kerä…
Multimodal Aposematic Defenses Through the Predation Sequence
2021
Aposematic organisms warn predators of their unprofitability using a combination of defenses, including visual warning signals, startling sounds, noxious odors, or aversive tastes. Using multiple lines of defense can help prey avoid predators by stimulating multiple senses and/or by acting at different stages of predation. We tested the efficacy of three lines of defense (color, smell, taste) during the predation sequence of aposematic wood tiger moths (Arctia plantaginis) using blue tit (Cyanistes caeruleus) predators. Moths with two hindwing phenotypes (genotypes: WW/Wy = white, yy = yellow) were manipulated to have defense fluid with aversive smell (methoxypyrazines), body tissues with a…
Infographics as a Reflective Assignment Method in Requirements Engineering e-Course?
2019
Our Work in Progress Paper in Innovative Practice Category focuses on how learners’ experience use of infographics in advanced level e-course on requirements engineering (RE). Infographics are visual representations of information in such a way that information can be easily understood at a glance. Most of the previous infographics studies have been conducted in the context of inquiry learning. To complement this research, we studied how learners experience use of infographics as a method for reflective assignment and hence if the usage of infographics supported conceptualization about RE. We adopted a qualitative content analysis approach, applying thematic network analysis to the data rec…
Evaluation of Student Teachers’ Perceived Quantitative Workload and Usefulness of an On-line Elementary Science Education Course Unit
2022
We have designed a 1 ECTS on-line science pedagogy unit as a part of a 6 ECTS science education course for elementary school student teachers. To improve the unit, we asked 169 participants to estimate their use of time and the usefulness of the themes and contents in it. We analysed the responses in the framework of students’ perceived workload. The Basics of School Science was perceived as the most useful section, followed by Science Teaching and Learning Methods and Basics of Science and Scientific Knowledge in Schools, respectively. This in mind, we discuss the rescaling of the workload and the respective weights student perception and teacher expertise should have in the process. peerR…
Digital Activism in Russia: The Evolution and Forms of Online Participation in an Authoritarian State
2020
AbstractThis chapter describes how digitalization has affected activism in Russia by tracing the evolution, particularity, and the most visible forms of online activism in the context of the increasingly authoritarian Russian state. It discusses online activism in relation to “connective action” and illustrates it with two examples of contentious political activism: the anti-corruption campaign led by Alexei Navalny and the struggle to protect online communication from state surveillance by the Telegram messenger service. In addition, the chapter presents examples of Russian activism, which do not directly challenge the Kremlin.
Medical masks and Respirators for the Protection of Healthcare Workers from SARS-CoV-2 and other viruses
2020
The use of medical masks and respirators as personal protective equipment is pivotal to reducing the level of biological hazard to which healthcare workers are exposed during the outbreak of highly diffusible pathogens, such as the recent novel coronavirus SARS-CoV-2. Unfortunately, during this pandemic, supplies are rapidly running out worldwide, with potential consequences for the rate of occupational infections. Also, knowledge about specific characteristics of respirators is of utmost importance to select the proper type according to the clinical setting. A wide variety of literature is available on the topic, but mostly based on Influenza viruses infection models. Clinical evidence on …
Understanding Estonian phraseological units on the basis of Finnish : contributing and misleading factors
2020
Vironkielistä tekstiä lukevien suomalaisten on havaittu hyödyntävän monenlaisia strategioita selvittääkseen sukukielen sanojen merkityksiä. Yksi niistä on pohjustaminen (priming). Kun kyseessä on fraseologinen yksikkö, yksi osa (prime) pohjustaa toisen osan eli kohdesanan (targetin) esiintymistä, mikäli prime on tunnistettavissa äidinkielen perusteella. Tässä artikkelissa kuvaamme muutamia erityistilanteita. Miten pohjustimen ja kohdesanan välinen etäisyys tai teemanvaihdos vaikuttavat ’petollisen ystävän’ ymmärtämiseen? Lisäksi tutkimme sitä, miten ahdasrajainen semanttinen kategoria ohjaa siitä puuttuvan jäsenen merkityksen löytämistä ja millaisia perusteita käännösratkaisuille on löydett…
Impacts of Touch Screen Size, User Interface Design, and Subtask Boundaries on In-Car Task's Visual Demand and Driver Distraction
2020
Visual distraction by secondary in-car tasks is a major contributing factor in traffic incidents. In-car user interface design may mitigate these negative effects but to accomplish this, design factors’ visual distraction potential should be better understood. The effects of touch screen size, user interface design, and subtask boundaries on in-car task's visual demand and visual distraction potential were studied in two driving simulator experiments with 48 participants. Multilevel modeling was utilized to control the visual demands of driving and individual differences on in-car glance durations. The 2.5” larger touch screen slightly decreased the in-car glance durations and had a diminis…
