Water bathing alters threat perception in starlings.

The majority of bird taxa perform water bathing, but little is known about the adaptive value of this behaviour. If bathing is important for feather maintenance then birds that have not bathed should have poorer feather condition, compromised escape ability and therefore increased responsiveness to cues of predation. We conducted two experiments examining the behaviour of captive starlings responding to conspecific alarm calls. Birds that had no access to bathing water showed a decreased willingness to feed and increased their vigilance behaviour following an alarm call. We argue that birds denied access to bathing water interpreted an ambiguous cue of threat as requiring more caution than birds that had access, consistent with higher levels of anxiety. Our results support the provision of bathing water for captive birds as an important welfare measure

Understanding the use, and misuse, of Adverse Childhood Experiences (ACEs) in trauma-informed policing

An increased awareness about how trauma impacts upon children and adults is vital for the identification of vulnerability, development of trauma-informed policing and strengthening the case for the prevention. ACEs provide an easily understandable framework which could help to develop trauma-informed practice and responses. However, there are potential misuses of ACEs in policing, for example using ACE scores or specific single ACEs as the basis for decisions or as intervention thresholds. In this article we review the current evidence with a focus on the strengths, current issues and risks in the use of ACEs across policin

Source-Relaxed Domain Adaptation for Image Segmentation

Domain adaptation (DA) has drawn high interests for its capacity to adapt a model trained on labeled source data to perform well on unlabeled or weakly labeled target data from a different domain. Most common DA techniques require the concurrent access to the input images of both the source and target domains. However, in practice, it is common that the source images are not available in the adaptation phase. This is a very frequent DA scenario in medical imaging, for instance, when the source and target images come from different clinical sites. We propose a novel formulation for adapting segmentation networks, which relaxes such a constraint. Our formulation is based on minimizing a label-free entropy loss defined over target-domain data, which we further guide with a domain invariant prior on the segmentation regions. Many priors can be used, derived from anatomical information. Here, a class-ratio prior is learned via an auxiliary network and integrated in the form of a Kullback-Leibler (KL) divergence in our overall loss function. We show the effectiveness of our prior-aware entropy minimization in adapting spine segmentation across different MRI modalities. Our method yields comparable results to several state-of-the-art adaptation techniques, even though is has access to less information, the source images being absent in the adaptation phase. Our straight-forward adaptation strategy only uses one network, contrary to popular adversarial techniques, which cannot perform without the presence of the source images. Our framework can be readily used with various priors and segmentation problems

Twitter and non-elites. Interpreting power dynamics in the life story of the (#)BRCA Twitter stream

In May 2013 and March 2015, actress Angelina Jolie wrote in the New York Times about her choice to undergo preventive surgery. In her two op-eds she explained that - as a carrier of the BRCA1 gene mutation - preventive surgery was the best way to lower her heightened risk of developing breast and ovarian cancer. By applying a digital methods approach to BRCA-related tweets from 2013 and 2015, before, during and after the exposure of Jolie’s story, this study maps and interprets Twitter discursive dynamics at two time points of the BRCA Twitter stream. Findings show an evolution in curation and framing dynamics occurring between 2013 and 2015, with individual patient advocates replacing advocacy organisations as top curators of BRCA content and coming to prominence as providers of specialist illness narratives. These results suggest that between 2013 and 2015, Twitter went from functioning primarily as an organisation-centred news reporting mechanism, to working as a crowdsourced specialist awareness system. This paper advances a twofold contribution. First, it points at Twitter’s fluid functionality for an issue public and suggests that by looking at the life story – rather than at a single time point – of an issue-based Twitter stream we can track the evolution of power roles underlying discursive practices and better interpret the emergence of non-elite actors in the public arena. Second, the study provides evidence of the rise of activist cultures that rely on fluid, non-elite, collective and individual social media engagement

Neuroethology of reward and decision making

Ethology, the evolutionary science of behaviour, assumes that natural selection shapes behaviour and its neural substrates in humans and other animals. In this view, the nervous system of any animal comprises a suite of morphological and behavioural adaptations for solving specific information processing problems posed by the physical or social environment. Since the allocation of behaviour often reflects economic optimization of evolutionary fitness subject to physical and cognitive constraints, neurobiological studies of reward, punishment, motivation and decision making will profit from an appreciation of the information processing problems confronted by animals in their natural physical and social environments

Methods A time-stratified case-crossover approach was used to examine this relationship in two adult national populations, between 1984 and 2007. Daily mortality risk was examined in association with exposure to daily maximum temperatures on the same day and up to 6 weeks preceding death, during the winter (December-February) and cold period (October-March), using distributed lag models. Model stratification by age and gender assessed for modification of the cold weather-mortality relationship. Results In the ROI, the impact of cold weather in winter persisted up to 35 days, with a cumulative mortality increase for all-causes of 6.4% (95%CI=4.8%-7.9%) in relation to every 1oC drop in daily maximum temperature, similar increases for cardiovascular disease (CVD) and stroke, and twice as much for respiratory causes. In NI, these associations were less pronounced for CVD causes, and overall extended up to 28 days. Effects of cold weather on mortality increased with age in both jurisdictions, and some suggestive gender differences were observed. Conclusions The study findings indicated strong cold weather-mortality associations in the island of Ireland; these effects were less persistent, and for CVD mortality, smaller in NI than in the ROI. Together with suggestive differences in associations by age and gender between the two Irish jurisdictions, the findings suggest potential contribution of underlying societal differences, and require further exploration. The evidence provided here will hope to contribute to the current efforts to modify fuel policy and reduce winter mortality in Ireland

Perinatal mental health and risk of child maltreatment: A systematic review and meta-analysis

BACKGROUND: Mental health problems in parents have been identified as a risk factor for child maltreatment. The perinatal period (from conception to 1 year) is a critical period but it is unclear whether perinatal mental health problems are also associated with increased risk. OBJECTIVE: To review evidence on perinatal mental health and risk of child maltreatment. METHODS: Searches were conducted on six databases and 24 studies reported in 30 papers identified. Studies were conducted in seven countries, mainly the USA (n = 14). Sample sizes ranged from 48-14,893 and most examined mothers (n = 17). Studies were conducted in community (n = 17) or high-risk (n = 7) samples. RESULTS: The majority of studies found a relationship between parental perinatal mental health problems and risk of child maltreatment, but inconsistent findings were observed between and within studies. The few studies that examined fathers (n = 6) all found a relationship between fathers' mental health and risk of child maltreatment. Meta-analysis of 17 studies (n = 22,042) showed perinatal mental health problems increased risk of child maltreatment by OR 3.04 (95% CI 2.29-4.03). This relationship was moderated by type of sample, with larger effects for risk of child maltreatment in high-risk samples. The relationship was not moderated by type of mental illness, child maltreatment; methodological or measurement factors. CONCLUSION: The association between perinatal mental health and risk of child maltreatment is similar to that observed at other times during childhood. Methodological heterogeneity and inconsistent findings mean conclusions are tentative and need to be considered alongside other individual, family and social/cultural risk factors

Exploring interprofessional collaboration during the implementation of a parent-infant mental health service: A qualitative study

We examined interprofessional working in a newly implemented parent-infant mental health service team supporting families experiencing bonding and attachment difficulties. The aim was to identify forms of interprofessional work undertaken, barriers and facilitators of this work, and families' and healthcare professionals' perceptions of it. Semi-structured interviews were carried out with 21 stakeholders (5 parents, 4 team clinicians, 9 service referrers, 3 service commissioners) and were analyzed thematically. Interprofessional activities identified included building the service team's cohesion and shared practice, building partner networks, interagency communication, coordination of roles, and raising awareness of infant mental health and parent-infant relationship needs. Enablers and barriers to interprofessional working were broadly consistent with findings from previous studies of related services, but with additional emphasis on consultative work as an enabler. Healthcare professionals reported benefiting from the case consultations and training on infant mental health provided by the service team. Parents reported that good interprofessional working enhanced satisfaction and engagement with the service. Findings indicate the centrality of interprofessional working for parent-infant mental health teams, with implications for future service implementation, service development, and understanding of mechanisms by which such services may influence family outcomes
