TL;DR: Investigation of the developmental dynamics of maths-related motivation and mathematical performance during children's transition to primary school in Finland showed that children's mathematical performance and related task motivation formed a cumulative developmental cycle.
Abstract: Background. It has been suggested that children's learning motivation and interest in a particular subject play an important role in their school performance, particularly in mathematics. However, few cross-lagged longitudinal studies have been carried out to investigate the prospective relationships between academic achievement and task motivation. Moreover, the role that the classroom context plays in this development is largely unknown.
Aims. The aim of the study was to investigate the developmental dynamics of maths-related motivation and mathematical performance during children's transition to primary school. The role of teachers' pedagogical goals and classroom characteristics on this development was also investigated.
Sample. A total of 196 Finnish children were examined four times: (0) in October during their preschool year; (1) in October and (2) April during their first grade of primary school; and (3) in October during their second grade.
Method. Children's mathematical performance was tested at each measurement point. Task motivation was examined at measurement points 2, 3, and 4 using the Task-value scale for children. First-grade teachers were interviewed in November about their pedagogical goals and classroom characteristics.
Results and conclusions. The results showed that children's mathematical performance and related task motivation formed a cumulative developmental cycle: a high level of maths performance at the beginning of the first grade increased subsequent task motivation towards mathematics, which further predicted a high level of maths performance at the beginning of the second grade. The level of maths-related task motivation increased in those classrooms where the teachers emphasized motivation or self-concept development as their most important pedagogical goal.

TL;DR: In this paper, a mediational model appropriate for explaining the effects of psychosocial job stressors, i.e., job insecurity, job autonomy, time pressures at work, leadership relations and work-family conflict, on marital satisfaction via job exhaustion and psychosomatic health, was tested among 215 married or cohabiting dual-earner couples.
Abstract: The focus on the present study was to test a mediational model appropriate for explaining the effects of psychosocial job stressors, i.e., job insecurity, job autonomy, time pressures at work, leadership relations and work–family conflict, on marital satisfaction via job exhaustion and psychosomatic health. The study was carried out among 215 married or cohabiting dual-earner couples. The proposed model was tested through structural equation analysis (LISREL). The results indicated that the job stressors, except for job autonomy, spilled over into marital satisfaction via job exhaustion and psychosomatic health for both men and women. However, no empirical support was found for the crossover of job stressors between partners, signifying that job stressors experienced by one partner did not influence the marital well-being of the other.

TL;DR: In this paper, the mean-field $s$-wave superconducting state of a bilayer graphene twisted around a certain magic angle was investigated and shown to evolve as the twist angle is tuned, and as a function of the doping level.
Abstract: Recent experiments show how a bilayer graphene twisted around a certain magic angle becomes superconducting as it is doped into a region with approximate flat bands. We investigate the mean-field $s$-wave superconducting state in such a system and show how the state evolves as the twist angle is tuned, and as a function of the doping level. We argue that part of the experimental findings could well be understood to result from an attractive electron-electron interaction mediated by electron-phonon coupling, but the flat-band nature of the excitation spectrum also makes the superconductivity quite unusual. For example, as the flat-band states are highly localized around certain spots in the structure, also the superconducting order parameter becomes strongly inhomogeneous.

TL;DR: Direct mass measurements of trans-uranium nuclides, located at the farthest tip of the actinide species on the proton number–neutron number diagram, represent the gateway to the predicted island of stability and advance direct mass measurements by ten atomic numbers with no loss in accuracy.
Abstract: The mass of an atom incorporates all its constituents and their interactions. The difference between the mass of an atom and the sum of its building blocks (the binding energy) is a manifestation of Einstein's famous relation E = mc(2). The binding energy determines the energy available for nuclear reactions and decays (and thus the creation of elements by stellar nucleosynthesis), and holds the key to the fundamental question of how heavy the elements can be. Superheavy elements have been observed in challenging production experiments, but our present knowledge of the binding energy of these nuclides is based only on the detection of their decay products. The reconstruction from extended decay chains introduces uncertainties that render the interpretation difficult. Here we report direct mass measurements of trans-uranium nuclides. Located at the farthest tip of the actinide species on the proton number-neutron number diagram, these nuclides represent the gateway to the predicted island of stability. In particular, we have determined the mass values of (252-254)No (atomic number 102) with the Penning trap mass spectrometer SHIPTRAP. The uncertainties are of the order of 10 keV/c(2) (representing a relative precision of 0.05 p.p.m.), despite minute production rates of less than one atom per second. Our experiments advance direct mass measurements by ten atomic numbers with no loss in accuracy, and provide reliable anchor points en route to the island of stability.
