Association of parental communication deviance with offspring's psychiatric and thought disorders. A systematic review and meta-analysis.
2013
AbstractElevated number of parental Communication Deviance (CD) has been connected with psychiatric and thought disorders in their offspring. However, no earlier systematic efforts have been made to review this issue. The aim of this study was to survey the existing literature systematically and perform a meta-analysis of this association. A literature search for published and unpublished observational studies on the association of parental Communication Deviance with psychopathology in the offspring was conducted. Multiple electronic databases were searched (from 1960 to 2012) and the reference lists of the resulting publications were scanned. The findings were pooled using random effect m…
Autonomous vehicle with communicative driving for pedestrian crossing: Trajectory optimization
2020
Connected and autonomous vehicles (CAV) is a key technology for this century. One of the main challenges is to define a smart interaction behavior of CAV with the other road users. The challenge is mainly raised at conflicting points where path of CAV intersects with the other users. Recent studies show interaction with humans is a big challenge. It not only requires a collision avoidance system but also more communicative behaviors of the CAV. More precisely, pedestrian needs to understand the intention of the incoming CAV whether it will cross first or not according to its speed profile. One way to overcome this issue is to design optimal trajectory control of the CAV that matches with th…
Effectiveness and user acceptance of infotainment-lockouts: A driving simulator study
2019
Abstract Lockout is a system-initiated distraction mitigation strategy that renders certain features of in-vehicle information systems (IVISs) non operable while the vehicle is in motion. The aim of this driving simulator study was to examine the influence of lockouts on driving performance and user acceptance. Overall, 52 participants performed six tasks with fully unlocked, partially locked, and completely locked IVIS. Within a repeated-measures design, we assessed user acceptance. As participants were free to decide where to conduct a secondary task, we could only analyse driving performance of 26 drivers. After each driving section, the participants rated the respective system with resp…
On the Objective Evaluation of Motion Cueing in Vehicle Simulations
2021
Motion-based simulators are used for a variety of applications, such as research, education, entertainment and training. In fact, motion cues are required to achieve the highest regulatory certifications in training vehicle simulators. Nonetheless, the reproduction of self-motion cues presents technological and economic limitations that are not present in the generation of audiovisual cues. For this reason, the generated motion does not generally match the expected one. Therefore, it is necessary to define means to assess the suitability/fidelity of the generated motion cues. After more than 50 years of motion-based vehicle simulation, no mechanism has been universally accepted as the stand…
Sharing cultural knowledge at work: a study of chat interactions of an internationally dispersed team
2015
Tässä artikkelissa tarkastellaan etnometodologisen jäsenkategorisoinnin analyysin avulla, kuinka kansainvälisesti hajautetun tiimin jäsenet jakavat kulttuurista tietoa Skype™ -keskusteluissaan. Tarkemmin katsotaan sitä, miten osallistujat luokittelevat itsensä ja muut tiimin jäsenet ’kulttuurisiksi tietäjiksi’ ja ’ei tietäjiksi’. Analyysissa havaittiin neljä tapaa, joilla tiimin jäsenet jakoivat tietoa samalla kun he hallinnoivat tehtävien jakelua ja suorittamista sekä rakensivat yhteisymmärrystä vuorovaikutuksessa. Tutkimuksen tulokset osoittavat, että kulttuurinen tieto on dynaamisesti muuttuvaa, kontekstisidonnaista ja vuorovaikutuksessa rakentuvaa. Sen sijaan että kulttuurisuus haittais…
(Im)Politeness and interactions in Dialogic Literary Gatherings
2016
Abstract This article examines the interactions that occur in Dialogic Literary Gatherings (DLG), a cultural activity in which low literate adults read and debate classic literature. To respect the principle of egalitarian dialogue, participants agree on how to communicate and reflect on their communicative patterns. We analyse the actual interactional behaviour of participants and the pragmatic traits that evidence how this principle is implemented by identifying dialogic and power interactions in connection to (Im)politeness. This study shows the influence of the situated genre (DLG) over status in the prevalence of politeness and how the participants use polite mitigation strategies that…
Affordances and constraints: Second language learning in cleaning work
2016
This paper examines opportunities for language learning in a cleaning job, which is a typical entry-level job for immigrants. An ethnographic case study approach is taken to investigate examples of the conditions that allow or prevent language learning for the focal participant, a sub-Saharan man who works as a cleaner in Finland. This case illustrates on a micro-scale the impact of the new economy on a worker in a company that has outsourced its cleaning services. Theoretically and methodologically, the study applies van Lier’s (2004) ecological approach to language learning and Scollon and Scollon’s (2004) nexus analysis. The analysis of interaction order shows that within outsourced clea…
‘What’s the Moment Thingy?’– On the Emergence of Subject-Specific Knowledge in CLIL Classroom Interaction
2017
Situated in the European CLIL context where mainstream schools may opt for teaching content subjects through the medium of a foreign or second language, this paper explores secondary school physics classrooms, taught through English in Finland. The focus is on the role of classroom interaction in the emergence of subject-specific knowledge during six consecutive lessons, with particular attention to how one key concept in physics, ‘moment’, is handled. This micro-longitudinal approach shows that while the students are struggling between the everyday and the academic meanings of the word ‘moment’ throughout, there are also clear signs of progression. These signs show, for example, in student…
$^{78}$Ni revealed as a doubly magic stronghold against nuclear deformation
2019
Nuclear magic numbers, which emerge from the strong nuclear force based on quantum chromodynamics, correspond to fully occupied energy shells of protons, or neutrons inside atomic nuclei. Doubly magic nuclei, with magic numbers for both protons and neutrons, are spherical and extremely rare across the nuclear landscape. While the sequence of magic numbers is well established for stable nuclei, evidence reveals modifications for nuclei with a large proton-to-neutron asymmetry. Here, we provide the first spectroscopic study of the doubly magic nucleus $^{78}$Ni, fourteen neutrons beyond the last stable nickel isotope. We provide direct evidence for its doubly magic nature, which is also predi…
Plant guttation provides nutrient-rich food for insects
2020
Plant guttation is a fluid from xylem and phloem sap secreted at the margins of leaves from many plant species. All previous studies have considered guttation as a water source for insects. Here, we hypothesized that plant guttation serves as a reliable and nutrient-rich food source for insects with effects on their communities. Using highbush blueberries as a study system, we demonstrate that guttation droplets contain carbohydrates and proteins. Insects from three feeding lifestyles, a herbivore, a parasitic wasp and a predator, increased their longevity and fecundity when fed on these guttation droplets compared to those fed on control water. Our results also show that guttation droplets…
