MENTAL HEALTH

New framework developed by Northumbria University will help prevent suicide among military veterans and serving personnel



Reports and Proceedings

NORTHUMBRIA UNIVERSITY



Researchers at Northumbria University are calling for better measures to be put in place, across the National Health Service (NHS) and military mental health specific charities, to prevent serving military personnel and veterans from taking their own lives.

A new report, led by academics from The Northern Hub for Veterans and Military Families Research at Northumbria, identifies that suicide among serving military personnel and military veterans – many of whom were known to services and recipients of care - could be reduced if those that were known to be vulnerable had access to the right help and assistance, at the right time, with the right intervention, and the right level of care and support.

The findings come from the report ‘One is too Many: A Conceptual Framework for Safety Planning within Service Delivery for Veterans and their Families’, a project funded with a grant from the Armed Forces Covenant Fund Trust’s "One Is Too Many" programme, which awarded grants to projects that aim to reduce suicide risks within vulnerable veterans in a coordinated and targeted way.

As well as in-depth interviews with serving military and veteran’s families bereaved by suicide, contributors to the new research included representatives from the health and social care sector, statutory agencies, third sector organisations, politicians, retired military personnel, funding agencies, and other critical stakeholders. This method of co-production identified three main aspects that would improve care provision for serving military personnel and veterans. These were a person-centred care approach, the need for a designated individual within the service provider to act as a single point of contact for the veteran and their family, and a centralised care service that would provide holistic support for the veteran and their family.

As part of their findings, the research team has produced an integrated toolkit for government, the NHS and military charities. The aim of this toolkit is to assist them in identifying gaps in care delivery and helping them build safer environments in which veterans and their families can be cared for. Researchers carried out in-depth interviews with military families across the UK who had been bereaved by suicide, capturing the detailed stories of families who have tragically lost their loved ones.

Multiple families repeated similar stories of being excluded and disconnected from support systems. This leads to further re-traumatisation and a compound effect in grief and mourning the loss of loved ones. According to the report’s lead author and Director of The Northern Hub for Veterans and Military Families Research, Professor Matthew Kiernan, this needs to change.

“These interviews identified critical problems with care delivery in the families’ stories,” he said. “Families strongly felt that they were not being heard, understood, valued, cared for, nor sufficiently empowered to be any part of care provision in terms preventing the loss of their loved one”.

“Many of them witnessed first-hand the slow decline of their loved one’s wellbeing – and felt helpless, and powerless in preventing what they saw as an inevitable outcome. Families’ experiences were that of passive care, often disjointed, uncoordinated, with frequent deficits in understanding and expected levels of compassion and active engagement”.

“As we move forward it is imperative that vital lessons are learnt here, and it is essential that families play a key role in their loved ones’ care provision.”

Researchers acknowledged the pressurised conditions that health service workers are under, with the study identifying significant evidence of compassion fatigue; – a complex consequence of the impact of helping others who have experienced stress or trauma. This is why the team at Northumbria have produced a toolkit as a self-assessment tool that will support the NHS, military charities and wider government departments in creating a safe environment which is focussed on training and education, improving services, strengthening resources, enhancing protective factors, and challenging stigma with both the serving military/ veterans and their families at the centre of care and intervention.

Dr Paul Watson, Assistant Director of the Northern Hub for Veterans and Military Families Research, said: “Clearly, there is insufficient understanding within the existing care provision around the journey towards suicide, and what systems and procedures need to be in place to identify, understand, and prevent death by suicide in this important population and beyond”.

“Promoting better levels of education and training is essential moving forwards.”

The stigma of negative attitudes, beliefs, and stereotypes is also harmful within the military and veterans’ population, often creating barriers to seeking help and resulting in potentially devastating effects. Enhancing better military/veteran-focussed mental health awareness which directly challenges the stigma of death by suicide is essential and the dual focus of client-centredness and family inclusivity is imperative, according to the report.

An Office for Veterans' Affairs spokesperson said: “Every veteran suicide is a tragedy. We welcome this research by Northumbria University, and will review it as part of our continued work to ensure veterans across the UK can access the right support.

"As part of our commitment to support veterans, Op COURAGE, our bespoke mental health pathway for veterans in England, is backed by over £21 million a year investment, which has seen over 35,000 referrals since it started."

Mental Health Issues in Seafarers

Mental health issues in seafarers have always been a concern, but the impact of COVID-19 heightened these issues even more and brought the issue into the open. Crew members faced a multitude of additional stressors while at sea during COVID, including concerns about family at home (especially if they were from high COVID prevalence countries), prolonged length of contracts (up to 400,000 seafarers beyond 8 months at one point), multiple extended contracts, travel restrictions getting home, inability to be present to mourn deceased relatives, forbidden or greatly limited shore leave and financial stressors. These were added to the everyday stressors potentially experienced by all crew such as strained interpersonal relationships in closed quarters with long contracts, threats of violence, sleep disturbances, boredom, low job satisfaction. performance of same job for prolonged periods – especially if high risk positions, and lack of communication with friends and family back home.

Isolation is a key factor in driving mental health issues, as crew members often feel cut off from their support systems.  Certain crew may be hindered by cultural and language barriers in seeking help. Additionally, certain cultures have a very high threshold for help-seeking behaviors and this may serve as a barrier to early identification, thereby increasing suicide risk. Studies have shown up to 20% of crew have contemplated suicide.

The issues of high stress, isolation and cultural variations in response to mental health problems must be managed pro-actively at the ship and corporate levels with pro-active program development and interventions.  Officers may be as severely affected as crew, limiting their potential for assistance and necessitating shared onboard and shoreside solutions. 

In addition to suicide and the direct manifestations of mental health issues, crew may become more prone to mistakes and accidents putting the ship, themselves, and fellow crew at risk.

A very important consideration is that underlying mental health issues such as depression, anxiety, and substance abuse are exacerbated by the conditions at sea.   The motivation for going to see must be examined and considered.  If it is to escape issues at home, it is rarely, if ever, effective. Isolation from normal social support systems can unmask underlying mental illness.  It is not uncommon to see the first manifestations of schizophrenia in a newly hired crew member during the first few months of their first contract and first time away from home.  Understanding and managing culturally specific mental health issues is crucial in providing effective support to seafarers.

Mental health screening must be a part of all PEME and REME programs.

AP Companies offers comprehensive PEME services, and we strongly advocate for the inclusion of mental health assessments in the required PEME/REME package. Prioritizing mental health evaluations not only promotes the wellbeing of the crew onboard but also mitigates potential financial and security risks, ultimately leading to cost savings.

The impact of other medical conditions must be considered. The effect of medications used to treat underlying medical problems, the inability to access appropriate medical care and lack of access to chronic medications may all have mental health implications.

The experiencing and communication of psychological stress as somatic symptoms, known as somatization, is a common occurrence among crew members, often leading to physical symptoms that prompt them to seek medical care - psychiatric conditions generating physical symptoms. Complaints of chest pains, headaches, back pain, insomnia, weakness, and tremors are leading cause of returning home crew members seeking medical care and are often due to somatization resulting in complex case management challenges.  The somatic complaint must be fully evaluated medically before concluding it is secondary to psychological issues and then addressing those issues.

Utilization of medical resources is a secondary measure that can be employed and can produce a justifiable ROI for mental health services.

COVID-19 also introduced new emotional and behavioral concerns for seafarers, with feelings of isolation, loneliness, and stigma becoming more prevalent. Recovery from the virus may also leave individuals at a greater risk of depression, anxiety, PTSD, cognitive issues and substance abuse, along with other conditions collectively known as “Long COVID”. These post infectious complaints must be taken seriously.

To address these mental health challenges, assistance must be offered to seafarers both on board and through various support programs. Designated mental health liaisons, additional training for captains and crew members, and culturally sensitive support programs need to be implemented to provide the necessary help. Videos, telephonic or online direct interventions and required YouTube videos are all strategies that can be deployed. Organizations such as ISWAN (International Seafarers’ Welfare and Assistance Network) also offer specific training programs and resources directed towards increased social interaction, connectivity, and mental health assistance.  Mitigating mental health issues for all crew by increasing positive social interaction and connectivity amongst crew, enhancing the ability to communicate with friends and family at home and developing robust crew wellness programs addressing sleep hygiene, exercise, hydration, and diet, as well as assuring the availability of medications must be part of corporate strategies.

AP Companies' Telemedical services include the availability of psychologists and psychiatrists for both crew members and officers. This provision ensures that the crew has continual access to essential support in their native language while also enabling captains to receive guidance on identifying mental health issues within the crew and effectively managing them onboard.

Accessing mental health assistance through medical case management assistance companies such as AP Companies is a valuable and much needed resource.

In conclusion, the mental health issues faced by seafarers are complex and pervasive, requiring proactive intervention and support from ship and corporate leaders. By addressing stressors, isolation, underlying mental health issues, somatization, and emotional concerns related to COVID-19, the well-being of seafarers can be better safeguarded. It is crucial to prioritize mental health awareness and assistance to ensure the safety and mental well-being of seafarers during these challenging times.

AI ethics are ignoring children, say Oxford researchers



UNIVERSITY OF OXFORD





Researchers from the Oxford Martin Programme on Ethical Web and Data Architectures (EWADA), University of Oxford, have called for a more considered approach when embedding ethical principles in the development and governance of AI for children.

In a perspective paper published today in Nature Machine Intelligence, the authors highlight that although there is a growing consensus around what high-level AI ethical principles should look like, too little is known about how to effectively apply them in principle for children. The study mapped the global landscape of existing ethics guidelines for AI and identified four main challenges in adapting such principles for children’s benefit:

  • A lack of consideration for the developmental side of childhood, especially the complex and individual needs of children, age ranges, development stages, backgrounds, and characters.
  • Minimal consideration for the role of guardians (e.g. parents) in childhood. For example, parents are often portrayed as having superior experience to children, when the digital world may need to reflect on this traditional role of parents.
  • Too few child-centred evaluations that consider children’s best interests and rights. Quantitative assessments are the norm when assessing issues like safety and safeguarding in AI systems, but these tend to fall short when considering factors like the developmental needs and long-term wellbeing of children.
  • Absence of a coordinated, cross-sectoral, and cross-disciplinary approach to formulating ethical AI principles for children that are necessary to effect impactful practice changes.

The researchers also drew on real-life examples and experiences when identifying these challenges. They found that although AI is being used to keep children safe, typically by identifying inappropriate content online, there has been a lack of initiative to incorporate safeguarding principles into AI innovations including those supported by Large Language Models (LLMs). Such integration is crucial to prevent children from being exposed to biased content based on factors such as ethnicity, or to harmful content, especially for vulnerable groups, and the evaluation of such methods should go beyond mere quantitative metrics such as accuracy or precision. Through their partnership with the University of Bristol, the researchers are also designing tools to help children with ADHD, carefully considering their needs and designing interfaces to support their sharing of data with AI-related algorithms, in ways that are aligned with their daily routes, digital literacy skills, and need for simple yet effective interfaces.

In response to these challenges, the researchers recommended:

  • increasing the involvement of key stakeholders, including parents and guardians, AI developers, and children themselves;
  • providing more direct support for industry designers and developers of AI systems, especially by involving them more in the implementation of ethical AI principles;
  • establishing legal and professional accountability mechanisms that are child-centred; and
  • increasing multidisciplinary collaboration around a child-centred approach involving stakeholders in areas such as human-computer interaction, design, algorithms, policy guidance, data protection law, and education.

Dr Jun Zhao, Oxford Martin Fellow, Senior Researcher at the University’s Department of Computer Science, and lead author of the paper, said:

‘The incorporation of AI in children’s lives and our society is inevitable. While there are increased debates about who should ensure technologies are responsible and ethical, a substantial proportion of such burdens falls on parents and children to navigate this complex landscape.’

‘This perspective article examined existing global AI ethics principles and identified crucial gaps and future development directions. These insights are critical for guiding our industries and policymakers. We hope this research will serve as a significant starting point for cross-sectoral collaborations in creating ethical AI technologies for children and global policy development in this space.’

The authors outlined several ethical AI principles that would especially need to be considered for children. They include ensuring fair, equal, and inclusive digital access, delivering transparency and accountability when developing AI systems, safeguarding privacy and preventing manipulation and exploitation, guaranteeing the safety of children, and creating age-appropriate systems while actively involving children in their development.

Professor Sir Nigel Shadbolt, co-author, Director of the EWADA Programme, Principal of Jesus College Oxford and a Professor of Computing Science at the Department of Computer Science, said:

‘In an era of AI powered algorithms children deserve systems that meet their social, emotional, and cognitive needs. Our AI systems must be ethical and respectful at all stages of development, but this is especially critical during childhood.’

Roots play a vital role in plant health, adapting to environmental changes and indicating crop growth. However, studying root senescence is challenging due to difficulties in obtaining clear in situ root images. Traditional methods are limited, and while in situ cultivation and advanced imaging techniques offer some solutions, they face issues such as high costs and low image quality. Recent advances in deep learning, particularly semantic segmentation models like SegNet and UNet, have improved root identification but still require further optimization.

In March 2024, Plant Phenomics published a research article entitled by “Improved Transformer for Time Series Senescence Root Recognition”. This study focuses on utilizing the RhizoPot system and exploring root segmentation models to enhance root senescence recognition, aiming to fill the gap in efficient, accurate root analysis for better plant health monitoring.

This paper evaluates eight segmentation models, including PSPNet, SegNet, UNet, DeeplabV3plus, TransUNet, SwinUNet, SETR, and a novel approach which is named SegFormer-UN trained uniformly for 100 epochs. The SegFormer-UN model, particularly its "Small" version, demonstrates superior performance with higher mIoU and mRecall rates of 81.06% and 86.29%, respectively, while maintaining lower computational demands (FLOPs and Params). Further, a "Large" version of SegFormer-UN even outperforms this with the highest recorded mIoU, mRecall, and mF1 scores. This indicates a clear advancement over traditional methods and other TransFormer neural networks, despite the deeper model requiring more computational resources.

In-depth analysis through ablation studies reveals that altering the upsampling method alone diminishes performance metrics compared to the base model, highlighting the complexity of optimizing segmentation accuracy. However, modifications in the decoder structure, specifically adopting the UNet and DeeplabV3plus decoders, show varied results. SegFormer-UN stands out by significantly enhancing the accuracy and reducing computational load, proving the effectiveness of integrating advanced decoders with the model's architecture.

Furthermore, the paper explores root senescence extraction, demonstrating the SegFormer-UN model's ability ,which can accurately classify and extract senescent roots rapidly, leveraging GPU acceleration. This method significantly outperforms traditional image processing techniques, reducing processing time from 31 minutes to about 4 minutes per image, and provides more precise root system identification despite challenges with occlusion by soil particles. Additionally, time-series analysis of root senescence, utilizing dimensionality reduction and clustering, indicates an increase in senescence proportion over time, validated by high R-Squared values from polynomial fitting.

In conclusion, the SegFormer-UN model, particularly its application to root segmentation and senescence extraction, exhibits a significant advancement in accuracy, efficiency, and computational economy. This study not only sets a new benchmark for root segmentation models but also emphasizes the potential for deep learning techniques in agricultural research, particularly in understanding root systems and their senescence patterns.

Successive and overlapping crises can lead to a lack of information, a flood of information that overwhelms essential information, or even distorted information. Society needs to be information resilient, that is resistant to crises, including disruptions related to information. According to a new study from the University of Vaasa, Finland, we need a culture that accepts uncertainty and imperfection of knowledge.

Aino Rantamäki' s doctoral dissertation at the University of Vaasa highlights the prerequisites for societal crisis resilience, particularly in relation to the informational dimension of crises.

Recent years have been marked by various crises and exceptional circumstances, such as the Covid 19 pandemic, the war in Ukraine, and the mobilisation of refugees on the Russian border. These crises are not all the same, but regardless of their type, they are all associated with uncertainty. Uncertainty is linked to a lack of information, particularly in the early stages of a crisis, and to the contradictory, unclear and even untruthful nature of information as the crisis progresses.

The lack of information is often responded to by massive information production, which can lead to the loss of information that is essential for action.

– Both incomplete and excessive information have consequences that undermine the capacity of individuals and society to act. It is not appropriate, let alone possible, to strive for perfect information, so instead of producing too much information, it is important to invest in building a common understanding of the situation and improving the usability of information, says Rantamäki, who will defend her dissertation at the University of Vaasa on 22 March 2024.

Crises are not only inevitable, but also necessary. They force us to remain vigilant, maintain preparedness, and develop skills and lessons learned.

Rantamäki stresses that although information resilience is realised during crises, it is built and strengthened in normal circumstances.

– Maintaining trust in society, building skills that are essential for information resilience and enabling foresight that leaves room for application are ways to strengthen the structures that support information resilience, says Rantamäki.

In addition, a common will is needed. Information resilience is built through interaction and cannot be the responsibility of a single actor or agency. This means that we need ways, space, and opportunities for dialogue between different groups of actors. According to Rantamäki, interaction in support of information resilience requires dialogue across sectors, levels, and disciplines, so that a common understanding of the situation can be built and rebuilt.

New results from multi-method research to support information resilience

Rantamäki's doctoral research takes a multi-method approach to information resilience. The study uses not only qualitative conceptual analysis and content analysis, but also network analysis linked to a more quantitative research tradition. The data consists of previous research literature, newspaper articles from the time of the Covid 19 pandemic, networks of stakeholders in the consultations behind the legislation, expert interviews, panels, and workshops.

The dissertation provides new scientific knowledge on information resilience in a governance context and a practical understanding of the means to support information resilience in society. The understanding built up in the dissertation can therefore be used both in future scientific research and in the development of, for example, social preparedness or organisational knowledge management.
