Temperament and migration patterns in Finland

Migration is a central determinant of population dynamics and structure. We examined whether three major temperament traits--sociability, emotionality, and activity--predicted migration propensity, selective urban-rural migration, and migration distance in a 9-year prospective study in Finland. The participants were Finnish women and men (N= 1,733) ages 15 to 30 years at baseline. The home municipality's position on the urban-rural continuum was assessed on the basis of the municipality's population density. We found that high sociability predicted migration to urban areas and longer migration distances. High activity increased general migration propensity (including migration to both urban and rural areas). High emotionality increased the likelihood of leaving the home municipality and decreased migration distances, but was not associated with selective urban-rural migration. These data suggest that temperament predicts the self-selection of environments on a demographic scale and may be relevant in understanding population dynamics.     

Effects of the Interaction Between Reaction Component of Personal Need for Structure and Role Perceptions on Employee Attitudes in Long‐Term Care for Elderly People1

This study examined the interaction of reaction component of personal need for structure (reaction to lack of structure, RLS) and role perceptions in predicting job satisfaction, job involvement, affective commitment, and occupational identity among employees working in long‐term care for elderly people. High‐RLS employees experienced more role conflict, had less job satisfaction, and experienced lower levels of occupational identity than did low‐RLS employees. We found individual differences in how problems in roles affected employees' job attitudes. High‐RLS employees experienced lower levels of job satisfaction, job involvement, and affective commitment, irrespective of role‐conflict levels. Low‐RLS employees experienced detrimental job attitudes only if role‐conflict levels were high. Our results suggest that high‐RLS people benefit less from low levels of experienced role conflicts.     

Adulthood EAS-temperament and carotid artery intima-media thickness: the Cardiovascular Risk in Young Finns study

We examined the association between adulthood emotionality-activity-sociability temperament scale and preclinical atherosclerosis and, whether this association is mediated by cardiovascular risk factors (low-density lipoprotein cholesterol, systolic blood pressure, diastolic blood pressure and body-mass index (BMI)). The participants were a nationally representative sample of 537 men and 811 women from the Cardiovascular Risk in Young Finns study aged 15-30 years at the baseline in 1992 and aged 24-39 years at the follow-up in 2001. Carotid atherosclerosis was assessed by ultrasound scans of the common carotid artery intima-media thickness (IMT) and brachial flow-mediated dilation (FMD). In men, there was an association between the temperament dimension activity and IMT (β = 0.08, p = 0.036) which was partially mediated by BMI (β decreased from 0.08 to 0.05; p-value of Sobel test = 0.002). However, after correction for multiple comparisons the association between IMT and the temperament dimension activity in men was only of borderline significance. In women, there were no associations between temperament and IMT or FMD. These results suggest that a highly active temperament may contribute to early signs of atherosclerosis in men and that body mass may mediate this association.     

Observation and analysis of large-scale human motion

Many team sports include complex human movement, which can be observed at different levels of detail. Some aspects of the athlete's motion can be studied in detail using commercially available high-speed, high-accuracy biomechanical measurement systems. However, due to their limitations, these devices are not appropriate for studying large-scale motion during a game (for example, the motion of a player running across the entire playing field). We describe an alternative approach to studying such large-scale motion, and present a video-based, computer-aided system, developed specifically for the purpose of acquiring large-scale motion data. The baseline of our approach consists of sacrificing much of the spatial accuracy and temporal resolution of widely used biomechanical measurement systems, to obtain data on human movement that span large areas and long intervals of time. Data can be obtained for each of the observed athletes with reasonable amount of operator work. The system was developed using the recordings of a handball match. Several field tests were performed to assess measurement error, including comparison to one of the widely available biomechanical measurement systems. With the help of the system presented, we could obtain position data for all 14 handball players on a 40 x 20 m large court with RMS error better than 0.6 m, covering 1 h of action. Several results, obtained during the handball match study are presented, in order to highlight the importance of large-scale motion acquisition.     

Authorship in a small medical journal: A study of contributorship statements by corresponding authors

The authorship criteria of the International Committee of Medical Journal Editors (ICMJE) are widely accepted in biomedical journals, but many studies in large and prestigious journals show that a considerable proportion of authors do not fulfill these criteria. We investigated authorship contributions in a small medical journal outside the scientific mainstream, to see if poor adherence to authorship criteria is common in biomedical journals. We analyzed statements on research contribution, as checked by the corresponding author, for individual authors of 114 research articles, representing 475 authors, submitted to the Croatian Medical Journal (CMJ) from 1999 to 2000. Only 40% of authors fulfilled the ICMJE authorship criteria. The authors listed first on the by-line were more likely to fulfill the authorship criteria than all other authors on the by-line. The percentage of authors fulfilling the ICMJE criteria of authorship decreased with the increase in the number of authors listed on the by-line. These results indicate that poor adherence to ICMJE authorship criteria is poor across biomedical journals, regardless of the size of the scientific community. Authorship and contributorship in biomedical journals, as well as editorial ethical responsibilities towards authorship criteria need critical redefinition and education of both editors and authors.

Development of allocentric spatial recall from new viewpoints in virtual reality

Using landmarks and other scene features to recall locations from new viewpoints is a critical skill in spatial cognition. In an immersive virtual reality task, we asked children 3.5–4.5 years old to remember the location of a target using various cues. On some trials they could use information from their own self‐motion. On some trials they could use a view match. In the very hardest kind of trial, they were ‘teleported’ to a new viewpoint and could only use an allocentric spatial representation. This approach provides a strict test for allocentric coding (without either a matching viewpoint or self‐motion information) while avoiding additional task demands in previous studies (it does not require them to deal with a small table‐top environment or to manage stronger cue conflicts). Both the younger and older groups were able to point back at the target location better than chance when they could use view matching and/or self‐motion, but allocentric recall was only seen in the older group (4.0–4.5). In addition, we only obtained evidence for a specific kind of allocentric recall in the older group: they tracked one major axis of the space significantly above chance, r(158) = .28, but not the other, r(158) = ?.01. We conclude that there is a major qualitative change in coding for spatial recall around the fourth birthday, potentially followed by further development towards fully flexible recall from new viewpoints.     

Gender differences and the awareness of plagiarism in higher education

Plagiarism is increasingly prevalent in the educational and research culture in higher education. Students are more and more looking for quick solutions when writing research papers and theses. In this paper, students’ awareness of plagiarism and possible gender differences in this awareness are presented. Gender differences in plagiarism awareness were analysed both generally and within several socio-economic contexts (e.g. social life, living with parents/grandparents, living in a student hall of residence, motivation for study and working during studies). Our study was conducted at the University of Maribor in Slovenia. The findings have revealed statistically significant gender differences in students’ plagiarism awareness; specifically, women have a much more negative attitude towards plagiarism than men. Regarding awareness, students could be divided into three groups: (1) students who are aware of plagiarism but do not consider it wrong or unethical, (2) students who are unaware of plagiarism, and (3) students who are aware of plagiarism but continue to plagiarise despite knowing it to be wrong. A very busy social life, strong motivation for study and working during studies also strongly affect plagiarism and reveal gender differences. Based on the findings of the study, this paper puts forward recommendations for plagiarism prevention. Our recommendations encompass the implementation of a plagiarism policy within academic institutions, strict sanctions on plagiarism, teaching students how to avoid plagiarism and, finally, a national programme for the promotion of academic integrity.
