People vary in the occurrence and perceived severity of stressors experienced in their daily lives. In the current study, the authors examined the extent to which individual differences in these relatively minor occurrences are determined by genetic endowment as well as environmental influences and how these effects vary by age. Identical (n-sub(pairs) = 111) and fraternal (n-sub(pairs) = 99) t...

We explore a minimal paradigm for thermalization, consisting of two weakly coupled, low dimensional, nonintegrable subsystems. As demonstrated for Bose-Hubbard trimers, chaotic ergodicity results in a diffusive response of each subsystem, insensitive to the details of the drive exerted on it by the other. This supports the hypothesis that thermalization can be described by a Fokker-Planck equat...

Over the past years, architectural aspects have been often defined as widely-scoped properties that naturally crosscut the boundaries of system components. This definition, however, neglects the concept of architectural style. Architectural styles prescribe different kinds of system decomposition and modularization by adopting distinct component and connector types. This position paper analyzes...

The human hand is a very useful multipurpose tool in all environments. However, performance capabilities are compromised considerably when gloves are donned. This is especially true for extra-vehicular activity (EVA) gloves used in a space environment. The primary aim of this study was to establish exertion and endurance limits for specific tasks. The objective of this study was to develop grip...

We present a novel theoretical mechanism that explains the capacity for non-enforceable communication about future actions to improve efficiency. We explore a two-player partnership game where, before choosing a level of effort to exert on a joint project, each player makes a cheap talk promise to their partner about their own future effort. We allow agents to incur a psychological cost of rene...

Walking on uneven surfaces or while undergoing perturbations has been associated with increased gait variability in both modeling and human studies. Previous gait research involving continuous perturbations has focused on sinusoidal oscillations, which can result in individuals predicting the perturbation and/or entraining to it. Therefore, we examined the effects of continuous, pseudo-random s...

The cosmological dynamics of minimally coupled scalar field that couples to the background matter with thermal interactions is investigated by using statefinder diagnostics. The time evolution of the statefinder pairs {r, s} and {r, q} are obtained under the circumstance that different values of model parameters are chosen. We show that the thermal coupling term does not affect the location of ...

Sabotage in Tournaments: Evidence from a Natural Experiment Many tournaments are plagued by sabotage among competitors. Typically, sabotage is welfare-reducing, but from an individual’s perspective an attractive alternative to exerting positive effort. Yet, given its illegal and often immoral nature, sabotage is typically hidden, making it difficult to assess its extent and its victims. Therefo...
