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…
Improved polyhedral descriptions and exact procedures for a broad class of uncapacitated p-hub median problems
2019
Abstract This work focuses on a broad class of uncapacitated p-hub median problems that includes non-stop services and setup costs for the network structures. In order to capture both the single and the multiple allocation patterns as well as any intermediate case of interest, we consider the so-called r-allocation pattern with r denoting the maximum number of hubs a terminal can be allocated to. We start by revisiting an optimization model recently proposed for the problem. For that model, we introduce several families of valid inequalities as well as optimality cuts. Moreover, we consider a relaxation of the model that contains several sets of set packing constraints. This motivates a pol…
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...
Validation of a questionnaire of attributions to the detection of coincidences in academic work
2019
El plagio como tema de investigación en el contexto universitario no ha cesado de ser una preocupación constante debido a sus múltiples repercusiones. El presente estudio describe el proceso seguido en la validación del Cuestionario de atribuciones para la detección de coincidencias en trabajos académicos (CUDECO), cuya finalidad es evaluar la relevancia que tiene citar correctamente y detectar las causas que llevan a cometer plagio. A partir de una muestra de 2,331 estudiantes, se realiza un anális is de la fiabilidad como consistencia interna y un análisis factorial exploratorio (AFE) del instrumento. El análisis de la fiabilidad lleva a proponer un reajuste en el cuestionario inicialment…
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…
Representations of Ethnicity in Journalism
2005
Abstract This article examines ethnic representations in the Finnish news discourse. Adopting a critical discourse analytical framework, the article examines textual manifestations of ethnic representations, the journalistic practices impinging on them and, finally, the significance of ethnic representations in the news. The study suggests that the marginalized position of ethnic minorities, journalistic practices and the insensitivity of the representational power of the news discourse together result in ethnic representations that contribute to the fragmentation of community, rather than to a sense of belonging.
Word classes and the scope of lexical flexibility in Tongan
2017
Abstract Tongan is an Oceanic language belonging to the Polynesian subgroup. Based on previous work (Churchward 1953, Tchekhoff 1981, Broschart 1997), Tongan has been classified as a 'flexible' language by various typological approaches on word classes (Hengeveld 1992, Rijkhoff 1998, Croft 2001). This means that lexical items are per se not categorised in terms of major word classes, but they can function as noun, verb, adjective and manner adverb without morphosyntactic derivation. However, not all lexemes are entirely flexible occurring within all these constructions. So the crucial issue of how flexible Tongan really is remains. This question will be addressed by a survey based on a comb…
Creación de un modelo estadístico predictivo para la determinación de las funciones de atenuación en español hablado
2018
Recientemente, algunos autores han definido distintas variables para caracterizar la atenuación lingüística en el marco de una base de datos multidimensional (Briz/Albelda; Albelda/otros). En este estudio se han seleccionado 982 elementos de atenuación de dieciocho entrevistas de español hablado; todos ellos han sido supervisados por hasta cuatro entrevistadores del proyecto Es.VaG.Atenuación. Finalmente, los datos se han evaluado mediante tres pruebas estadísticas para la clasificación y la reducción de variables: el análisis múltiple de correspondencias, el árbol de clasificaciones y el Random Forest. Las variables más determinantes en la discriminación de las funciones de atenuación han …
Teachers’ perspectives on telecollaboration in secondary school foreign language education
2018
In recent years, telecollaboration has proved to be a useful tool in the acquisition of foreign languages and intercultural communicative skills (Belz 2003b; Clavel-Arroitia, Pennock-Speck 2015a, 2015b; Hewitt, Brett 2007; O’Dowd 2007; Su et al., 2005). This paper focuses on how prepared secondary-school teachers believe they are in order to successfully implement telecollaboration in the classroom. To gather information on their views we carried out an online survey of 179 secondary school foreign language teachers and a series of focus group interviews in the context of a European project, TeCoLa. The advantage of the double- pronged approach to data collection, quantitative and qualitati…
