Family structure,maternal employment,and change in children's externalizing problem behaviour: Differences by age and self-regulation

This study used a latent difference score growth model to investigate how changes in family structure (biological father and stepfather residence) and maternal employment are associated with American children's externalizing problem behaviours (EPB) from ages 4–10 and whether these associations vary by children's level of self-regulation. For all 4-year-old children, living with a biological father at age 4 was associated with reductions in EPB at ages 4–6 and later years, with no variation by child self-regulation. Living with a stepfather at age 4 was associated with higher levels of EPB at age 4; however, for less-regulated children, stepfather residence at ages 4 and 8 was associated with reductions in EPB between ages 4–6 and 8–10, respectively. Greater employment hours were associated with increased EPB in the next 2 years for less-regulated children of all ages; however, except for the age 4–6 transition, there was a lagged association that reduced behaviour problems after 2 years and outweighed short-term increases.     

The role of learning and career guidance for managing mid-career transitions – comparing Germany and Denmark

In Germany and Denmark, the systems of further education and career guidance are well developed, offering a wide range of services and learning opportunities for targeted, specific and also general skills development. Based on an empirical study with mid-career individuals in both countries, the article investigates how the different systems support individuals to manage a career transition and develop their individual pathways. Mid-career transitions can be considered particularly challenging as they often reflect a more profound crisis and major concerns about future career opportunities. Constraints that prevent individuals in mid-career to fully benefit from the learning and guidance offers available can be identified in both countries. These range from the availability of programmes and accessing funding to getting the ‘right’ information. These constraints partly derive from adult education and guidance systems presupposing linear careers rather than disruptive trajectories and horizontal mobility.     

Regulation of exercise behaviour and motives for physical activities: The Italian validation of BREQ and MPAM-R questionnaires

Based on self-determination theory, the purpose of the present study was to provide the first Italian validation of two different instrument to assess the exercise behaviour: the Mullan et al.’s (1997) BREQ, which measures external, introjected, identified and intrinsic forms of regulation and Ryan et al.’s (1997) MPAM-R, which assesses five distinct motives for physical activity (appearance, health and fitness, social, competence, and enjoyment). Confirmatory factor analysis conducted on data collected from 1995 students attending three different secondary schools empirically supported respectively the four-factor structure of behavioural regulation and the five-factor structure of motives for physical activity, supporting convergent and discriminant validity of both scales. Furthermore, multi-group confirmatory factor analysis showed the invariance of the factor structures, structural parameters and correlations of the two scales across gender. Criterion-related validity of the scales also received partial empirical support. Finally, the factor structure of behavioural regulation and motives for physical activity was empirically supported when both constructs were included in a single measurement model.     

Enhanced encoding of the co-actor's target stimuli during a shared non-motor task

Task co-representation has been proposed to rely on the motor brain areas’ capacity to represent others’ action plans similarly to one's own. The joint memory (JM) effect suggests that working in parallel with others influences the depth of incidental encoding: Other-relevant items are better encoded than non-task-relevant items. Using this paradigm, we investigated whether task co-representation could also emerge for non-motor tasks. In Experiment 1, we found enhanced recall performance to stimuli relevant to the co-actor also when the participants’ task required non-motor responses (counting the target words) instead of key-presses. This suggests that the JM effect did not depend on simulating the co-actor's motor responses. In Experiment 2, direct visual access to the co-actor and his actions was found to be unnecessary to evoke the JM effect in case of the non-motor, but not in case of the motor task. Prior knowledge of the co-actor's target category is sufficient to evoke deeper incidental encoding. Overall, these findings indicate that the capacity of task co-representation extends beyond the realm of motor tasks: Simulating the other's motor actions is not necessary in this process.     

Repeated usage of a motorway automated driving function: Automation level and behavioural adaption

The user’s perspective on highly automated driving systems is mostly studied during first contact/single usage. However, with repeated usage, acceptance and usage of automated driving systems might change. For advanced driving assistance systems, change with growing system usage is studied as behavioural adaptation. This concept of behavioural adaptation is applied to highly automated driving systems. In a driving simulator study, N = 61 drivers used an automated driving system for motorways during six experimental sessions. The drivers were free to activate / deactivate the function as they liked and to spend driving time on self-chosen side tasks. Automation level was varied as a between-subject factor (L3 vs. L4). Results show a more positive evaluation of the L4 system and behavioural adaptation for both levels over the course of the six sessions. For most aspects, behavioural adaptation is independent of system level (e.g., for system evaluation, distribution of attention). Only for drivers’ reaction to requests to intervene, a strong impact of system level on the occurrence behavioural adaption can be found. The results are discussed with regard to the theory of behavioural adaptation.     

共产主义信念对道德认知的影响及认知机制

Behavioural intention to use fully autonomous vehicles: Instrumental,symbolic, and affective motives

Autonomous Vehicles (AVs) have the potential to transform the transportation industry with significant economic, social and environmental benefits. However, the mass deployment of AVs depends on public desire to use them. This study aims to examine the effect of instrumental, symbolic, and affective motives on the behavioural intention to use fully AVs. Based on a survey of 240 U.S. residents, a structural equation modeling analysis was performed. Our results suggest the behavioural intention to use fully AVs depends on fulfilling instrumental (i.e., performance expectancy and hedonic motivation), symbolic (i.e., personal innovativeness and social influence) and affective motives (i.e., trust and performance risk). These results have implication for designing policy interventions to increase the deployment of AVs.

A new orthorhombic approximant of the icosahedral Al–Cu–Fe quasicrystal

We report on the formation of a new crystalline approximant phase of the icosahedral (i-)Al–Cu–Fe quasicrystal. This phase is formed during sintering of Al-based composites reinforced with i-AlCuFeB quasicrystalline particles. The structure of this phase has been characterized by transmission electron microscopy (TEM) and high-resolution electron microscopy (HREM). TEM revealed that it is a B-centred orthorhombic phase with lattice parameters a = 1.166 nm, b = 1.195 nm and c = 3.44 nm. Its chemical composition, as determined by electron energy loss spectroscopy (EELS), is close to Al_76.9Cu_2.7Fe_20.4, with an average number of valence electrons per atom e/a of 1.92, similar to the value in all other approximants of the i-phase discovered thus far. Initial results on local atomic arrangements along one of its pseudo-5-fold axes are also presented.     

Effect of lithium-ion irradiation on the crystallization kinetics of glassy Se98In2

Differential scanning calorimetry (DSC) has been used to study the crystallization kinetics of glassy Se₉₈In₂ both before and after irradiation of the alloy with high-energy (50 MeV) lithium ions. After the ion-irradiation, significant changes in the kinetic parameters of crystallization of the glass were observed. The results are explained in terms of a model involving irradiation-induced defects.
