Parent peer advocacy, mentoring, and support programs, delivered by parents with lived child protection (CP) experience to parents receiving CP intervention, are increasingly recognized internationally as inclusive practices that promote positive outcomes, but little is known about what shared characteristics exist across these types of programs and what variations may exist in service delivery or impact. This scoping review examines 25 years (1996-2021) of empirical literature on these programs to develop a systematic mapping of existing models and practices as context for program benefits and outcome achievement. Studies were selected using a systematic search process.

First Direct Detection Constraints on Planck-Scale Mass Dark Matter with Multiple-Scatter Signatures Using the DEAP-3600 Detector.

Phys Rev Lett

January 2022

Instituto de Física, Universidad Nacional Autónoma de México, A.P. 20-364, México D.F. 01000, México.

Dark matter with Planck-scale mass (≃10^{19}  GeV/c^{2}) arises in well-motivated theories and could be produced by several cosmological mechanisms. A search for multiscatter signals from supermassive dark matter was performed with a blind analysis of data collected over a 813 d live time with DEAP-3600, a 3.3 t single-phase liquid argon-based detector at SNOLAB.

Cognitive Impairment Impacts Exercise Effects on Cognition in Multiple Sclerosis.

Front Neurol

January 2021

Department of "Performance and Health (Sports Medicine)", Institute of Sport and Sport Science, Technical University Dortmund, Dortmund, Germany.

Exercise training reveals high potential to beneficially impact cognitive performance in persons with multiple sclerosis (pwMS). Research indicates that high-intensity interval training (HIIT) has potentially higher effects on physical fitness and cognition compared to moderate continuous exercise. This study (i) compares the effects of a 3-week HIIT and moderate continuous exercise training on cognitive performance and cardiorespiratory fitness of pwMS in an overall analysis and (ii) investigates potential effects based on baseline cognitive status in a subgroup analysis.

The somatotopy of observed emotions.

Cortex

August 2020

Cognitive Neuroscience Research Unit, Department of Psychology, City, University of London, Northampton Square, EC1V 0HB, London, UK.

The ability to experience others' emotional states is a key component in social interactions. Uniquely among sensorimotor regions, the somatosensory cortex (SCx) plays an especially important role in human emotion understanding. While distinct emotions are experienced in specific parts of the body, it remains unknown whether the SCx exhibits somatotopic activations to different emotional expressions.

Unprecedented herbivory threatens rear-edge populations of Betula in southwestern Eurasia.

Ecology

November 2019

Departamento de Sistemas y Recursos Naturales, ETSI de Montes, Forestal y del Medio Natural, Universidad Politécnica de Madrid, Madrid, 28040, Spain.

Mediterranean rear-edge populations of Betula, located at the southwestern Eurasian margin of the distribution range, represent unique reservoirs of genetic diversity. However, increasing densities of wild ungulates, enhanced dryness, and wildfires threaten their future persistence. A historical perspective on the past responses of these relict populations to changing herbivory, fire occurrence and climatic conditions may contribute to assessing their future responses under comparable scenarios.

First Results from the DEAP-3600 Dark Matter Search with Argon at SNOLAB.

Phys Rev Lett

August 2018

TRIUMF, Vancouver, British Columbia V6T 2A3, Canada.

This Letter reports the first results of a direct dark matter search with the DEAP-3600 single-phase liquid argon (LAr) detector. The experiment was performed 2 km underground at SNOLAB (Sudbury, Canada) utilizing a large target mass, with the LAr target contained in a spherical acrylic vessel of 3600 kg capacity. The LAr is viewed by an array of PMTs, which would register scintillation light produced by rare nuclear recoil signals induced by dark matter particle scattering.

Land-use history as a guide for forest conservation and management.

Conserv Biol

February 2018

Institute of Plant Sciences, University of Bern, Altenbergrain 21, 3013, Bern, Switzerland.

Conservation efforts to protect forested landscapes are challenged by climate projections that suggest substantial restructuring of vegetation and disturbance regimes in the future. In this regard, paleoecological records that describe ecosystem responses to past variations in climate, fire, and human activity offer critical information for assessing present landscape conditions and future landscape vulnerability. We illustrate this point drawing on 8 sites in the northwestern United States, New Zealand, Patagonia, and central and southern Europe that have undergone different levels of climate and land-use change.

The sense of body-ownership relies on the representation of both interoceptive and exteroceptive signals coming from one's body. However, it remains unknown how the integration of bodily signals coming from "outside" and "inside" the body is instantiated in the brain. Here, we used a modified version of the Enfacement Illusion to investigate whether the integration of visual and cardiac information can alter self-face recognition (Experiment 1) and neural responses to heartbeats (Experiment 2).

The kinematics of upper limb movements and the coordination of eye and hand movements are affected by ageing. These age differences are exacerbated when task difficulty is increased, but the exact nature of these differences remains to be established. We examined the performance of 12 older adults (mean age = 74) and 11 younger adults (mean age = 20) on a multi-phase prehension task.

Electrophysiological correlates of self-specific prediction errors in the human brain.

Neuroimage

January 2016

Lab of Action & Body, Department of Psychology, Royal Holloway University London, Egham Surrey, TW20 0EX London, UK.

Recognising one's self, vs. others, is a key component of self-awareness, crucial for social interactions. Here we investigated whether processing self-face and self-body images can be explained by the brain's prediction of sensory events, based on regularities in the given context.

Regulation of the activity of N-methyl-d-aspartate receptors (NMDARs) at glutamatergic synapses is essential for certain forms of synaptic plasticity underlying learning and memory and is also associated with neurotoxicity and neurodegenerative diseases. In this report, we investigate the role of Src-like adaptor protein (Slap) in NMDA receptor signaling. We present data showing that in dissociated neuronal cultures, activation of ephrin (Eph) receptors by chimeric preclustered eph-Fc ligands leads to recruitment of Slap and NMDA receptors at the sites of Eph receptor activation.

Background: It is becoming increasingly evident that deficits in the cortex and hippocampus at early stages of dementia in Alzheimer's disease (AD) are associated with synaptic damage caused by oligomers of the toxic amyloid-β peptide (Aβ42). However, the underlying molecular and cellular mechanisms behind these deficits are not fully understood. Here we provide evidence of a mechanism by which Aβ42 affects synaptic transmission regulating neurotransmitter release.

Self-organized criticality in human epidemiology.

AIP Conf Proc

July 2005

Mathematics Department, Porto University, Portugal NIC, Research Center Jülich, Germany.

As opposed to most sociological fields, data are available in good quality for human epidemiology, describing the interaction between individuals being susceptible to or infected by a disease. Mathematically, the modelling of such systems is done on the level of stochastic master equations, giving likelihood functions for real live data. We show in a case study of meningococcal disease, that the observed large fluctuations of outbreaks of disease among the human population can be explained by the , leading the system towards a critical state, characterized by power laws in outbreak distributions.
