title: A latent profile analysis of the Big Five personality and mindfulness traits in the general population

authors: Strohmaier, Sarah

abstract: Understanding how personality and mindfulness traits influence responses to health and wellbeing interventions is important for improving their effectiveness, in particular since there is likely not a one-size-fits-all approach for mindfulness. While various interventions show overall benefits, individual differences likely determine optimal intervention types and doses. A multinational sample of 636 general population adults (57.2 % female) completed self-report measures of personality and mindfulness traits, and state positive and negative affect scales before being randomly assigned to a single mindfulness practice of 5-min, 20-min, or an active control, after which state scales were completed again. The personality and mindfulness data were subjected to latent profile analysis, revealing three profiles, labelled 1) Mindful-adaptive, 2) Reserved-disengaged, and 3) Ruminative-preoccupied. Secondary analyses showed significant medium to large effects for profile 3 (Ruminative-preoccupied) across all groups. For profile 2 (Reserved-disengaged), shorter mindfulness practice had a significant medium to large effect. No significant interactions were found for profile 1 (Mindful-adaptive). Findings suggest that personality-mindfulness profiles predict differential responses to brief interventions. This has practical implications for personalizing health and wellbeing interventions based on individual personality characteristics. Our study provides a novel person-centered approach to understanding intervention effectiveness through personality profiling.

title: Zircon response to high-grade metamorphism as revealed by U–Pb and cathodoluminescence studies

authors: Siebel, Wolfgang

subjects: Bohemian Massif

abstract: The Acigöl rhyolite field erupted the most recent high-silica rhyolites within the Cappadocian Volcanic Province of central Anatolia, Turkey. It comprises two sequences of domes and pyroclastic rocks with eruption ages of ∼150–200 ka (eastern group) and ∼20–25 ka (western group). Compositionally, the eastern rhyolite group lavas are less evolved (SiO₂ = 74–76 wt%), whereas the western group has higher silica abundance (SiO₂ = ∼77 wt%) with extremely depleted feldspar-compatible trace elements. Within each group, compositional variability is small and ¹⁴³Nd/¹⁴⁴Nd (0.51257–0.51265) and Pb isotope compositions (²⁰⁶Pb/²⁰⁴Pb = 18.87–18.88, ²⁰⁷Pb/²⁰⁴Pb = 15.65–15.67 and ²⁰⁸Pb/²⁰⁴Pb = 38.94–38.98) are homogeneous. The western group rhyolites have δ¹⁸O(zircon) overlapping mantle values (5.7 ± 0.2%), whereas eastern group rhyolites are enriched in d18O by ∼ 0.5%, consistent with a tendency to lower εNd values. By contrast, western group rhyolites have markedly more radiogenic ⁸⁷Sr/⁸⁶Sr ratios (0.7065–0.7091) compared to those of the eastern group (0.7059–0.7065). The presence of angular granitic xenoliths and a correlation between hydration (based on loss on ignition data) and ⁸⁷Sr/⁸⁶Sr in the western lavas, however, indicates that Sr was added during the eruption or posteruption alteration. Isotope constraints preclude the possibility that the rhyolite magmas formed by partial melting of any known regional crystalline basement rocks. Basalts and andesites erupted in the periphery of the Acigöl field are characterised by ⁸⁷Sr/⁸⁶Sr ratios between 0.7040 and 0.7053, ¹⁴³Nd/¹⁴⁴Nd = 0.51259–0.51300, ²⁰⁶Pb/²⁰⁴Pb = 18.85– 18.87, ²⁰⁷Pb/²⁰⁴Pb = 15.646–15.655, ²⁰⁸Pb/²⁰⁴Pb =38.90–38.97. The isotopic and trace element data favour an origin of the rhyolites by mixing of basaltic/andesitic magmas with minor amounts of crustal melts and followed by extensive fractional crystallization.

title: Using the stars to indigenize the public sphere: Matariki over New Zealand

authors: Hardy, Anna

subjects: Arts & Humanities

abstract: As the rate of affiliation to Christian identity continues to decline in Aotearoa New Zealand (only 49 percent of the population said they were Christian in the last census), public space has become more receptive to other forms of religiosity. In particular, community rituals around the winter movements of the Matariki (Pleiades) constellation have gained support since the year 2000. For instance, the capital city, Wellington, has replaced a centuries’ old British fireworks festival, Guy Fawkes, with an enlarged version of its Matariki celebrations: an action seen as a tipping point in the incorporation of Māori spiritual values into public life. Interactions between European colonisers and Māori have been characterised for more than 250 years by tensions between the relational thinking of Māori who see human beings as both participating in and constrained by an environment resonant with divine energies, and the quantitative, hierarchical, ‘Great Chain of Being’ model that had long been dominant among Europeans. Now, when the natural environment worldwide is under strain from population and economic pressures, it seems to some both appropriate and vital to look to epistemological and spiritual models that are intimately responsive to the specificities of location.
