A hypercubic Mk model framework for capturing reversibility in disease, cancer, and evolutionary accumulation modelling.

Motivation: Accumulation models, where a system progressively acquires binary features over time, are common in the study of cancer progression, evolutionary biology, and other fields. Many approaches have been developed to infer the accumulation pathways by which features (e.g.

On Being Open in Closed Places: Vulnerability and Violence in Inpatient Psychiatric Settings.

High levels of violence and conflict occur in inpatient psychiatric settings, causing a range of psychological and physical harms to both patients and staff. Drawing on critiques of vulnerability from the philosophical literature, this paper contends that staff's understanding of their relationship with patients (including how they should respond to violence and conflict) rests on the dominant, reductive account of vulnerability. This account frames vulnerability as an increased susceptibility to harm and so regards 'invulnerable' staff's responsibility to be protecting and managing vulnerable patients.

HyperTraPS-CT: Inference and prediction for accumulation pathways with flexible data and model structures.

Accumulation processes, where many potentially coupled features are acquired over time, occur throughout the sciences from evolutionary biology to disease progression, and particularly in the study of cancer progression. Existing methods for learning the dynamics of such systems typically assume limited (often pairwise) relationships between feature subsets, cross-sectional or untimed observations, small feature sets, or discrete orderings of events. Here we introduce HyperTraPS-CT (Hypercubic Transition Path Sampling in Continuous Time) to compute posterior distributions on continuous-time dynamics of many, arbitrarily coupled, traits in unrestricted state spaces, accounting for uncertainty in observations and their timings.

De-escalating aggression in acute inpatient mental health settings: a behaviour change theory-informed, secondary qualitative analysis of staff and patient perspectives.

Background: De-escalation is often advocated to reduce harm associated with violence and use of restrictive interventions, but there is insufficient understanding of factors that influence de-escalation behaviour in practice. For the first time, using behaviour change and implementation science methodology, this paper aims to identify the drivers that will enhance de-escalation in acute inpatient and psychiatric intensive care mental health settings.

Methods: Secondary analysis of 46 qualitative interviews with ward staff (n = 20) and patients (n = 26) informed by the Theoretical Domains Framework.

Evolution and maintenance of mtDNA gene content across eukaryotes.

Across eukaryotes, most genes required for mitochondrial function have been transferred to, or otherwise acquired by, the nucleus. Encoding genes in the nucleus has many advantages. So why do mitochondria retain any genes at all? Why does the set of mtDNA genes vary so much across different species? And how do species maintain functionality in the mtDNA genes they do retain? In this review, we will discuss some possible answers to these questions, attempting a broad perspective across eukaryotes.
