Personality Traits Are Associated With Cortical Development Across Adolescence: A Longitudinal Structural MRI Study

How personality traits relate to structural brain changes in development is an important but understudied question. In this study, cortical thickness (CT) and surface area (SA), estimated using magnetic resonance imaging (MRI), were investigated in 99 participants aged 8–19 years. Follow‐up MRI data were collected after on average 2.6 years for 74 individuals. The Big Five personality traits were related to longitudinal regional CT or SA development, but limited cross‐sectional relations were observed. Conscientiousness, emotional stability, and imagination were associated with more age‐expected cortical thinning over time. The results suggest that the substantial individual variability observed in personality traits may partly be explained by cortical maturation across adolescence, implying a developmental origin for personality–brain relations observed in adults.     

Student attitudes that predict participation in peer assessment

Peer assessment has been widely applied to actively engage students in learning to write. However, sometimes students resist peer assessment. This study explores reviewers’ attitudes and other underlying factors that influence students’ participation in online peer assessment. Participants were 234 Chinese undergraduates from two different academic backgrounds: engineering majors (n = 168) and English majors (n = 66). Gender, academic background and prior experience with peer assessment were all related to participation levels. Moreover, factor analyses revealed three attitudinal factors: (1) positive attitude (a general endorsement of the benefits of peer assessment), (2) interpersonal negative (concerns about the negative effects on interpersonal relationships), and (3) procedural negative (doubts about the procedural rationality of peer assessment). Among the attitudinal factors, procedural negative was negatively associated with participation, as expected. Interestingly, interpersonal negative was associated with greater participation, and positive attitude was associated with lower participation, in part because students worked hard on each review rather than doing many reviews superficially. Implications for instruction are discussed.     

The climate for entrepreneurship at higher education institutions

While the importance of a supportive context for entrepreneurship is widely acknowledged, its antecedents are rarely investigated. We apply the concept of organizational climate to higher education institutions and examine the drivers of students’ perceptions of the entrepreneurial climate in their university. Combining data from two unique datasets and using multilevel techniques, we analyze the relationship between university characteristics and such climate perceptions of 8009 students at public universities in Germany. We find university entrepreneurship measures to have a positive effect on students’ climate perceptions, which also depend on students’ background and gender. In addition, we find evidence for different peer effects, depending on students’ affinity for entrepreneurship. For the general student population, including entrepreneurship content in their normal studies seems to be required to initiate a social process of sensemaking. However, students’ perception of the entrepreneurial climate only depend to a certain degree on intentional entrepreneurship measures. In our study, general university characteristics have the strongest influence on climate perceptions. Overall, our study adds to our understanding of which parameters are important for establishing a more favorable and inspiring climate for becoming an entrepreneur at higher education institutions.     

Sozialer Status und Spendenverhalten Ehrenamtlicher in Sportvereinen

While much research has been done to analyze whether socioeconomic status influences prosocial behavior in the form of donations, no consensus has yet emerged in the relevant literature. We contribute to this research by studying, based on a dataset from a questionnaire of volunteers of sports clubs in Palatinate (part of Rhineland–Palatinate, Germany) whether social status affects donations. We measured social status of volunteers of sports clubs along the dimensions income, vocation, education and we considered status crystallization. Results showed that social status has a positive effect on the likelihood of donations. We report similarities and differences across different categories of donations (donations to one’s own sports club, to other clubs, to aid projects, and political parties).     

Engines at top speed! Using the adventures of a comic book motorsports hero as an approach to understanding recent French history

Jean Graton created a series of comic books called Michel Vaillant, and its motorsports hero bore the same name. Michel Vaillant made his first appearance in 1957 in the weekly Tintin. Young French boys who loved adventure, sports and car racing greeted this publication with great enthusiasm. We studied the first series of Michel Vaillant, composed of 16 comic books produced in the 1960s. We have departed from traditional approaches and have based our method on the analysis of the sources of Graton’s inspiration. We link these sources to the comics’ text bubbles, visual signs and iconic meanings of the drawings. Our analysis of the comics’ iconography based on the establishment of a mass culture dedicated to the automobile brings to light the existence of an urge to go beyond the limits of tradition. Our research highlights that the success of Michel Vaillant is due, in the main, to the series’ detailed knowledge of the automobile sports industry, and to the myths of speed, youth and progress that it promulgates – myths in which its young male readers could see themselves reflected and which would also prepare them for the future.     

Improving Silent Reading Performance Through Feedback on Eye Movements: A Feasibility Study

This feasibility study investigated if feedback about individual eye movements, reflecting varying word processing stages, can improve reading performance. Twenty-five university students read 90 newspaper articles during 9 eye-tracking sessions. Training group participants (n = 12) were individually briefed before each session, which eye movement parameter(s) (fixation count, first fixation duration, regression, and/or skipping) to address, and informed about changes achieved in preceding sessions. Control group participants (n = 13) were told that self-instruction to read faster would produce training gains. Total fixation times decreased significantly more for training than for control group participants. Important to note, faster reading did not impair comprehension. Results are interpreted as first indications for a possible applicability of the feedback approach to silent reading. In addition to implications for future studies, alternative result interpretations (e.g., motivational effects, reduction of mindless reading) are discussed.     

Actions and Conceptions: Exploring Initial Literacy Teaching Practice for Adults

Given that it is a delicate task to meet the educational needs of adult emergent readers in a second language setting, this study serves to explore the teaching practice of teachers working with learners of initial literacy and second language. Based on a situated learning perspective, data from 16 lesson observations of nine teachers is analysed. The findings show that teachers initiate and negotiate learning activities, strive to get the students to understand words and other symbols, facilitate participation within and outside the classroom and negotiate the acceptable student behaviour. These findings suggest that Literacy Education and Second Language Learning for Adults (LESLLA) teaching and learning is a particular practice, where the teachers’ actions are intertwined with those of the learners and with the teachers’ conceptions of the learners. In that way, the teachers’ actions do not only speak of the learners, but also of their own professional identity.     

Creatine kinase,myosin heavy chains and magnetic resonance imaging after eccentric exercise

The aim of this study was to examine the relationship between myosin heavy chain (MHC) release as a specific marker of slow-twitch muscle fibre breakdown and magnetic resonance imaging (MRI) of skeletal muscle injury after eccentric exercise. The effects of a single series of 70 high-intensity eccentric contractions of the quadriceps femoris muscle group (single leg) on plasma concentrations of creatine kinase and MHC fragments were assessed in 10 young male sport education trainees before and 1 and 4 days after exercise. To visualize muscle injury, MRI of the loaded thigh was performed before and 4 days after the eccentric exercise. All participants recorded an increase ( P ? 0.05) in creatine kinase after exercise. In five participants, T2 signal intensity was unchanged post-exercise compared with pre-exercise and MHC plasma concentration was normal; however, they showed an increase ( P ? 0.05) in creatine kinase after exercise. For the remaining five participants, there was an increase in T2 signal intensity of the loaded vastus intermedius and vastus lateralis. These changes in MRI were accompanied by an increase in MHC plasma concentration ( P ? 0.01) as well as an increase in creatine kinase ( P ? 0.01). We suggest that changes in MRI T2 signal intensity after muscle damage induced by eccentric exercise are closely related to damage to structurally bound contractile filaments of some muscle fibres. Additionally, MHC plasma release indicates that this damage affects not only fast-twitch fibres but also some slow-twitch fibres.
