The Semiotics of Test Design: Conceptual Framework on Optimal Item Features in Educational Assessment Across Cultural Groups, Countries, and Languages
2021
This paper offers a conceptual framework on test design from the perspective of social semiotics. Items are defined as arrangements of features intended to represent information, convey meaning, and capture information on the examinees’ knowledge or skills on a given content. The conceptual framework offers a typology of semiotic resources used to create items and discusses item representational complexity—the multiple ways in which the semiotic resources of an item are related to each other—and item semiotic alignment—the extent to which examinees share cultural experience encoded by items. Since the ability to make sense of items is shaped by the examinees’ level of familiarity with the s…
Obsessional and Eating Disorder-related Intrusive Thoughts: Differences and Similarities Within and Between Individuals Vulnerable to OCD or to EDs
2016
Unwanted intrusive cognitions constitute the normal variant of clinically significant intrusive cognitions found in disorders such as obsessive-compulsive disorder (OCD) and eating disorders (EDs). This study investigates whether individuals who are vulnerable to OCD or EDs experience more intrusions than people with no vulnerability to these disorders, and it examines the consequences of obsessional (OITs) and eating disorder (EDITs) intrusions in the same individuals, taking into account their susceptibility to OCD, EDs or neither of the two. From a sample of 922 participants, three groups were formed: risk of OCD (n = 92), risk of EDs (n = 41) and a no-risk group (n = 100). EDITs were mo…
Online Supportive Group as social intervention to face COVID lockdown. A qualitative study on psychotherapists, psychology trainees and students, and…
2021
Several psychological interventions have been activated to help people during the Coronavirus pandemic, and research highlights the crucial role of group interventions as a space for sharing and processing the psychological experiences linked to this emergency and the consequent changes in people’s lifestyles. In this context, psychologists are mostly providers of this kind of service more than users. This study aimed at investigating and comparing post-hoc the subjective experience of psychotherapists, psychology trainees & students, and individuals of the general population who participated in a psychodynamically-oriented supportive group intervention. Fifty-two subjects were enrolled…
Driver ageing does not cause higher accident rates per km
2002
Abstract Based on Finnish survey data, older (65+, n =1559) and younger (26–40, n =310) drivers’ accident rates were compared. In accordance with earlier studies, the rates were similar per driver (0.1) but there was a non-significant trend towards older drivers having more accidents per distance driven (10.8 vs. 8.3 per 1 million km). However, when the accidents-per-km comparison was made in groups matched for yearly exposure, there is no evidence for higher risk with increasing age. In both age groups, risk per km decreased with increasing yearly driving distance. We suggest that the previous perception of an age-related risk increase of accidents per distance driven arises from a failure…
The Impact of Negative Parasocial and Vicarious Contact with Refugees in the Media on Attitudes toward Refugees
2019
Contact with members of outgroups is an important factor for ingroup members’ attitudes toward these groups. Ingroup members can also come into contact with outgroups in the media. This media conta...
Social interaction in management group meetings: a case study of Finnish hospital.
2016
Purpose – The purpose of this paper is to understand the role of management group meetings (MGMs) in hospital organization by examining the social interaction in these meetings. Design/methodology/approach – This case study approaches social interaction from a structuration point of view. Social network analysis and qualitative content analysis are applied. Findings – The findings show that MGMs are mainly forums for information sharing. Meetings are not held for problem solving or decision making, and operational coordinating is limited. Meeting interaction is very much focused on the chair, and most of the discussion takes place between the chair and one other member, not between members…
1-(v,3,r) designs and the equation x+y+z=0 in finite abelian groups
2009
Let (G, +) be a finite abelian group with more than three elements and let B_3 be the family of all the unordered triples {x,y,z} of distinct elements of G such that x+y+z=0. We show that (G, B_3) is a 1-(v,3,r) design if and only if G is either an elementary abelian 3-group or the direct sum of Z/2Z with an elementary abelian 3-group. We also characterize the groups containing at least an element that does not belong to any triple in B_3
Magic informationally complete POVMs with permutations
2017
Eigenstates of permutation gates are either stabilizer states (for gates in the Pauli group) or magic states, thus allowing universal quantum computation [M. Planat and Rukhsan-Ul-Haq, Preprint 1701.06443]. We show in this paper that a subset of such magic states, when acting on the generalized Pauli group, define (asymmetric) informationally complete POVMs. Such IC-POVMs, investigated in dimensions $2$ to $12$, exhibit simple finite geometries in their projector products and, for dimensions $4$ and $8$ and $9$, relate to two-qubit, three-qubit and two-qutrit contextuality.

Differences in Participation and Performance Trends in Age Group Half and Full Marathoners
2014
International audience; Recent studies investigated participation and performance trends in age group half marathoners and full marathoners for a single event. The present study investigated participation and performance trends in age group athletes in all half marathons and full marathons held in a single country during a given period of time. Changes in running performance and age of 226,754 half marathoners and 86,419 full marathoners competing in Switzerland between 2000 and 2010 were analyzed using linear regression analyses. The number of half marathoners increased (P < 0.01) from 2000 to 2010 for both men (+231%) and women (+299%). In contrast, the number of male and female full mara…
