Universality of the reversal transition in growth phenomena of molecular crystals

ABSTRACT

The fundamental origin of the reversal transition during crystal growth has been investigated by Monte Carlo simulations. Evidence is provided supporting the geometrical nature of the transition, arising from the broken translational invariance at the growth front and the interactions of multipoles of opposed parity. The range of interactions, the details of the force field and model are irrelevant to the occurrence and only determine the functional behaviour of the relevant physical quantities like the localisation of the critical point and the morphology of the phase diagram.     

Mystery,Values, and Meaning: Religious Options that Respect Science

Abstract

Human nature is a contested concept and notions of it vary across disciplines. Despite this diversity, three basic notions of human nature emerge. One identifies human nature with properties that are innate, hardwired or products of some kind of necessary essence. Another understands it as consisting of properties that make human unique or distinct from non-human animals. Finally, some seek human nature by attempting to identify universal or near-universal properties of humans. While the sciences might not give us a robust form of innate or hardwired human nature, “human nature” as a concept might still serve other, non-scientific, goals.     

Increases in Tolerance Within Naturalistic, Intentional Communities: A Randomized, Longitudinal Examination

The authors examine differential changes in values of tolerance among 150 participants discharged from inpatient treatment centers, and randomly assigned to either a self-help-based, communal living setting (i.e., Oxford House), or usual aftercare. Participants were interviewed every 6 months for a 24-month period. Hierarchical linear modeling (HLM) was used to examine the effect of condition (therapeutic communal living versus usual aftercare) on wave trajectories of tolerance (i.e., universality/diversity scores). Over time, residents of the communal living model demonstrated significantly greater values of tolerance than usual aftercare participants. Communal living participants who resided in the house for over 6 months showed the most substantial increases in tolerance. Results support the notion that communal living residents may develop more tolerant attitudes by striving toward superordinate community goals (objectives held by (a) the whole group and (b) which individual members could not achieve alone).
