Cognitive and affective processes associated with moral reasoning, and their relationship with behaviour in typical development

Objective: Moral reasoning (MR) reflects rationalisation in the moral domain, which matures across development and is underpinned by cognitive and affective processes. Although MR is associated with offending behaviours the mechanisms for this association are unknown. Examining the role of cognitive and affective processes in MR, and their influence on behaviour, may enhance existing psychological interventions that aim to reduce offending behaviours, and facilitate the development of novel targeted interventions. The current study investigated the hypothesis that MR would mediate the relationship between executive functions (EFs) and behaviour, and between empathy and behaviour. Method: In a cross-sectional design, typically developing adolescents (n = 72) individually completed an assessment battery, including the sociomoral reflection measure-short form, neuropsychological measures of working memory and cognitive flexibility/inhibition, and self-report questionnaires of empathy and behaviour. The battery also contained an assessment of intellectual functioning, and obtained data on socioeconomic status and age as confounding variables. Results: MR was not associated with self-report behaviour and, therefore, did not mediate the relationship between EFs/empathy and self-reported behaviour. A novel relationship was demonstrated between working memory and MR, and cognitive flexibility/inhibition was associated with MR. Self-report empathy was not associated with MR. Exploratory analyses suggested that intelligence and EFs were significant unique predictors of MR, and that truth and law moral values were associated with self-reported behavioural difficulties. Conclusions: Findings suggest that global MR is not associated with self-reported behaviour in typically developing adolescents, however, there may be an association between some moral values and self-reported behaviour. Findings also suggested that empathy is not associated with MR in this population, which warrants further investigation. These findings have implications for theoretical models of MR, and psychological intervention programmes. Recommendations for future research are presented

JSoLangs: ephemeral esolangs in a collaborative live coding environment

This paper documents the initial stages of an experiment in creating ephemeral live coding languages - “JSoLangs” - for diverse artistic, educational, and critical purposes. The experiment takes place in the context of the larger Estuary project: a browser-based, collaborative platform that allows multiple, distinct live coding notations/languages to interoperate. An emerging feature of the Estuary platform is the ability to create ephemeral esolangs (esoteric programming languages) on the fly, within a collaborative Estuary ensemble. These “JSoLangs” take the form of small (or not so small) JavaScript programs that transpile live coded text into one or more of Estuary’s underlying languages

Orbital scale variability and evolution of the Indian Monsoon during the Pliocene: new data from the Andaman Sea

The Indian summer monsoon (ISM) is a critical component of the overarching Asian monsoon system, which dominates seasonal rainfall patterns over the region. The underlying mechanisms controlling monsoon variability include internal forcings (e.g., ice volume, ocean circulation) and external forcings (e.g., solar insolation), operating over a range of time scales from tectonic to decadal. While there is now considerable data from regions dominated by the SE Asian monsoon, there remains a significant data gap for the regions affected by the Indian monsoon, particularly prior to the late Pleistocene. Many unknowns remain regarding the response of ISM to past changes in global climate, such as during the intensification of Northern Hemisphere glaciation in the late Pliocene (~2.5–3.5 Ma). Key questions centre on the role of external vs. internal forcing at controlling both long-term and orbital-scale monsoon variability, and whether wind and rainfall responses were coupled during these transitions. Here, we present a high resolution (~4 kyr), benthic oxygen isotope age model spanning from ~2.4 to 4.0 Ma for IODP Site U1448 in the Andaman Sea. This record allows us to interrogate (X-ray fluorescence) bulk elemental data from the same core to reconstruct past ISM behaviour across this enigmatic interval. Trends in elemental ratios representing terrestrial runoff and marine productivity (linked to ISM strength) show both long-term evolution in response to changing boundary conditions, and the influence of orbital forcing. Additionally, high resolution benthic carbon isotope data allows us to track changes in both water mass and marine productivity associated with orbital-scale variability in this region. Comparison of this data with comparable data from IODP Site U1445 in the NW Bay of Bengal allow us to examine spatial and temporal trends in ISM strength during the Pliocene, and identify changing loci of dominant precipitation across this region with time

A new high-resolution chronology for the late Maastrichtian warming event: establishing robust temporal links with the onset of Deccan volcanism

The late Maastrichtian warming event was defined by a global temperature increase of ∼2.5–5 °C that occurred ∼150–300 k.y. before the Cretaceous-Paleogene (K-Pg) mass extinction. This transient warming event has traditionally been associated with a major pulse of Deccan Traps (west-central India) volcanism; however, large uncertainties associated with radiogenic dating methods have long hampered a definitive correlation. Here we present a new high-resolution, single species, benthic stable isotope record from the South Atlantic, calibrated to an updated orbitally tuned age model, to provide a revised chronology of the event, which we then correlate to the latest radiogenic dates of the main Deccan Traps eruption phases. Our data reveal that the initiation of deep-sea warming coincides, within uncertainty, with the onset of the main phase of Deccan volcanism, strongly suggesting a causal link. The onset of deep-sea warming is synchronous with a 405 k.y. eccentricity minimum, excluding a control by orbital forcing alone, although amplified carbon cycle sensitivity to orbital precession is evident during the greenhouse warming. A more precise understanding of Deccan-induced climate change paves the way for future work focusing on the fundamental role of these precursor climate shifts in the K-Pg mass extinction

Triumph and tribulation for shallow water fauna during the Paleocene–Eocene transition; insights from the United Arab Emirates

This is the final version. Available on open access from Borntraeger Science Publishers via the DOI in this recordThe Paleocene–Eocene transition was a time of short-term rapid climatic and biotic change, superimposed on a long-term warming trend. The response of shallow tropical carbonate systems to past rapid warming is important to understand in the context of ongoing and future anthropogenic global warming. Larger benthic foraminifera (LBF) were abundant and important components of shallow water ecosystems throughout the early Paleogene and are sensitive to environmental change, making them ideal organisms to track shallow marine biodiversity. Furthermore, through the use of integrated bio- and chemostratigraphy it is possible to correlate the shallow (<100 m) and deep water realms to create a regional stratigraphic framework for the time period. Here we present a new LBF biostratigraphic and high-resolution carbonate carbon isotopic record spanning the Paleocene– Eocene transition from the onshore sub-surface of the United Arab Emirates (UAE). Results show a turnover event in the LBF assemblage during the early Eocene, wherein there are a number of first and last occurrences of species. However, assemblages remain generally stable coincident with the large negative carbon isotope excursion interpreted to be the onset of the Paleocene–Eocene thermal maximum (PETM). Turnover in the LBF assemblage in the early Eocene likely occurred due to the crossing of a long-term climatic and oceanographic threshold. The impacts of this long-term climatic change on the overall biotic assemblage at this site are significant, with LBF outcompeting a previously diverse community of corals, gastropods, and bivalves to become the dominant carbonate producers through the Paleocene–Eocene transition. Despite this, modern studies suggest that LBF are not immune to impacts of anthropogenic climate change, perhaps due to the significantly higher rates of change in the modern compared to the Paleocene–Eocene transition.Natural Environment Research Council (NERC)European Research Council (ERC

Coupled evolution of temperature and carbonate chemistry during the Paleocene–Eocene; new trace element records from the low latitude Indian Ocean

This is the final version. Available on open access from Elsevier via the DOI in this recordThe early Paleogene represents the most recent interval in Earth’s history characterized by global greenhouse warmth on multi-million year timescales, yet our understanding of long-term climate and carbon cycle evolution in the low latitudes, and in particular the Indian Ocean, remains very poorly constrained. Here we present the first long-term sub-eccentricity-resolution stable isotope (δ13 30 C and δ 18 O) and trace element (Mg/Ca and B/Ca) records spanning the late Paleocene–early Eocene (~58– 53 Ma) across a surface–deep hydrographic reconstruction of the northern Indian Ocean, resolving late Paleocene 405-kyr paced cyclicity and a portion of the PETM recovery. Our new records reveal a long-term warming of ~4–5°C at all depths in the water column, with absolute surface ocean temperatures and magnitudes of warming comparable to the low latitude Pacific. As a result of warming, we observe a long-term increase in δ 18 Osw of the mixed layer, implying an increase in net evaporation. We also observe a collapse in the temperature gradient between mixed layer- and thermocline-dwelling species from ~57–54 Ma, potentially due to either the development of a more homogeneous water column with a thicker mixed layer, or depth migration of the Morozovella in response to warming. Synchronous warming at both low and high latitudes, along with decreasing B/Ca ratios in planktic foraminifera indicating a decrease in ocean pH and/or increasing dissolved inorganic carbon, suggest that global climate was forced by rising atmospheric CO2 concentrations during this time.European Consortium for Ocean Research Drilling (ECORD)International Association of Sedimentologists (IAS)NSFNatural Environment Research Council (NERC

An astronomically dated record of Earth's climate and its predictability over the last 66 million years.

Much of our understanding of Earth's past climate comes from the measurement of oxygen and carbon isotope variations in deep-sea benthic foraminifera. Yet, long intervals in existing records lack the temporal resolution and age control needed to thoroughly categorize climate states of the Cenozoic era and to study their dynamics. Here, we present a new, highly resolved, astronomically dated, continuous composite of benthic foraminifer isotope records developed in our laboratories. Four climate states-Hothouse, Warmhouse, Coolhouse, Icehouse-are identified on the basis of their distinctive response to astronomical forcing depending on greenhouse gas concentrations and polar ice sheet volume. Statistical analysis of the nonlinear behavior encoded in our record reveals the key role that polar ice volume plays in the predictability of Cenozoic climate dynamics
