    • Subject positions of British South Asian women with inflammatory bowel disease: a Foucauldian discourse analysis

      Purewal, Satvinder; Stavroulaki, Angeliki; School of Psychology, Faculty of Education, Health and Wellbeing (University of Wolverhampton, 2024)
      The prevalence of inflammatory bowel disease (IBD) among British South Asians (BSA) is increasing. Evidence suggests that people of BSA background are more likely to develop IBD than white Europeans. Research on women with IBD is primarily focused on reproduction, which limits our understanding of their IBD experience and its consequences. This study aimed to investigate how BSA women discursively construct their experience of IBD, how this links to overarching sociocultural and medical discourses, and what the disciplines of counselling psychology (CP) and health can do to improve it. The data were collected through semi-structured interviews with eight BSA women with IBD and analysed using Foucauldian Discourse Analysis (FDA). The analysis revealed subject positions sourced in sociocultural and medical discourses. These were the Seeker Woman, the Private Woman, the Flawed Woman, and the Empowered Woman. These subject positions illustrate how sociocultural factors and medical practices influence BSA women’s subjectivity and actions. The study indicated that BSA gender stereotypes and attitudes towards women impact their experience and highlighted the societal dynamics that medical professionals, mental health providers, and politicians must address to deliver care customised to the specific needs of BSA women with IBD. Suggestions and recommendations for future research and policy are made.
    • Deep learning for DDoS attack detection in mobile edge computing

      Pillai, Prashant; Adeniyi, Olusola; School of Engineering, Computing and Mathematical Sciences, Faculty of Science and Engineering (University of Wolverhampton, 2024)
      Mobile edge computing (MEC) has become a disruptive technology that brings computation closer to end users, reducing latency and allowing faster response times. However, MEC like other networks is facing cyber security issues, particularly the Distributed Denial of Service attack (DDoS) which has become common in recent years. Compared to cloud environments, MEC networks have their own constraints, including limited resources and computational power. These constraints necessitate a careful consideration of how available ML solutions against DDoS attacks can be adapted to suit MEC environment. To achieve a robust and resilient MEC network, there is a need for a proactive self-healing approach towards DDoS attacks. Therefore, this study aims to provide an innovative approach for MEC networks to predict and remediate attacks. This study proposes three categories of solutions that could help provide a resilient MEC network taking into consideration its key constraints. In the first category, this study proposes Feedforward Neural Network (FNN) as a lightweight algorithm that can be deployed on the MEC platform. A simple FNN architecture is computationally efficient and relatively easy to train, which is useful in a resource-constrained environment such as MEC. Also, in this category this study proposes TinyML based DDoS detection model which can be used in an embedded device with low energy and bandwidth consumption. Secondly, the study proposes a hybrid deep learning algorithm (AE-MLP) and a cloud edge collaboration where training is done in the cloud environment and the algorithm is deployed at the edge for faster and more accurate prediction. Finally, a global orchestration mitigation strategy against DDoS attacks is proposed using a new nonlinear Lévy Brownian Generalized Normal Distribution Optimization (NLBGNDO) algorithm. Experimental results using NF-UQ-NIDS-V2 datasets, a recent dataset with new attacks, show that the FNN algorithm achieved an accuracy of 87.63% while the TinyML achieved 91.89%. In the second category of solutions, the hybrid AE-MLP achieved a higher accuracy of 99.98%. The NLBGNDO optimisation algorithm gave superior performance when compared with other optimisation algorithms. By developing a proactive self-healing approach, this research contributes to enhancing the security posture of MEC environments. It offers the potential to improve the resilience of these systems against DDoS attacks and reduce their destructive impact.
    • The impact of technology orientation, strategic firm resources and resource orchestration on small high-tech firms innovation: evidence from the UK

      Wang, Yong; Aguda, Akinbowale; University of Wolverhampton Business School, Faculty of Arts, Business and Social Sciences (University of Wolverhampton, 2024-12)
      Innovation is the driving force of a high-tech small business and plays a vital role in developing the firm's competitiveness and achieving sustainable growth. High-tech firms are a significant force for innovation as they are primarily private firms and the main foundation of the UK private sector. This thesis endeavours to unravel the innovation dilemma of high-tech firms by examining how strategic firm resources and the use of these strategic firm resources are exploited in their innovation process to achieve innovation performance. Firstly, this study draws upon the resource-based view and resource orchestration theory to examine how technology orientation influences innovation performance. Secondly, this study examines the impact of strategic firm resources (availability of technological resources, availability of financial resources, networking capability, and degree of openness) on the relationship between technology orientation and innovation performance. Thirdly, this study examines the role of resource orchestration (structuring, bundling, and leveraging) between the availability of strategic firm resources and innovation performance. Based on a quantitative study, this thesis examines the mechanism of the innovation process using quantitative survey data from 141 high-tech small and medium-sized enterprises (SMEs). The key findings of this thesis revealed that technology orientation positively impacts innovation performance. Furthermore, the results show that the availability of technological resources, networking capability, and the degree of openness positively affect the nexus of technology orientation and innovation performance. In contrast, the availability of financial resources does not positively impact the relationship between technology orientation and innovation performance. Furthermore, other key findings show that resource orchestration (structuring, bundling and leveraging) impacts the relationship between the availability of strategic firm resources and innovation performance. Specifically, structuring, bundling and leveraging positively and partially mediate the relationship between strategic firm resources (availability of technological resources, networking capability, and degree of openness) and innovation performance. However, regarding the availability of financial resources, structuring has a negative impact on the relationship between the availability of financial resources and innovation performance, whilst bundling and leveraging have a full mediating effect on the relationship between the availability of financial resources and innovation performance. This research extends the understanding of the innovation process in high-tech small firms by exploring the role and orchestration of resources. It tackles the problem of how high-tech firms can achieve innovation performance with scarce resources. Moreover, it enhances the literature on UK high-tech firm's innovation, which provides new knowledge about high-tech business in a developed country, contributing to a more holistic picture of high-tech business innovation worldwide. Finally, the study makes a methodological contribution to the study of the innovation performance of high-tech firms by providing a comprehensive understanding of the innovation performance in UK high-tech small firms as it examines two levels of the mediating effect of availability of strategic firm resources and orchestration of strategic firm resources and integrating both resource-based view and resource orchestration theory.
    • Gathering Press: towards environmentally resonant pedagogies

      Onions, Laura (Birmingham Centre for Media and Cultural Research, Birmingham City University, 2024-11-04)
      This practice-led paper considers the ongoing cartography and emerging pedagogies of Gathering Press, a roving screen-printing project moving within the Black Country, West Midlands, UK. The text considers the inter-relations between people, place and making, drawing upon feminist geographers and educators to explore how a resource that is unhinged from a single location can develop opportunities for community learning that are attentive to the specificities of place. From the local market and library to the canal-side, the layered and incremental moments of doing and making are embodied through a pedagogy of place and placemaking in which one scenario takes the process to somewhere else. This example mentioned initiates a discussion on the nature of the press as an object that becomes more fully itself afterwards.
    • A needs analysis and recommendations for physical assessments and training adaptations for judo athletes with visual impairments: a brief review

      Kons, Rafael Lima; Weldon, Anthony; Bishop, Chris; Cloak, Ross; Detanico, Daniele (Lippincott, Williams & Wilkins, 2025-12-31)
      This paper reviews the unique needs, performance aspects, and assessment recommendations for judo athletes with visual impairments. A needs analysis reveals the importance of custom training strategies and environmental adaptations to facilitate training and competition. Performance aspects, including time-motion analysis and match-related performance, are discussed to elucidate the specific demands and movement patterns in judo athletes with visual impairment. Additionally, recommendations are proposed to develop standardized protocols for physical assessment and skill evaluation, ensuring the optimization of training strategies. Collaborative research initiatives are recommended to further explore integrating multisensory stimuli and enhance athletic development in this population. By addressing the unique challenges judo athletes with visual impairment face and providing evidence-based recommendations for performance assessment and training optimization, this review contributes to advancing adapted sports science and promoting inclusivity and excellence in judo.
    • A systematic review of the existing evidence on early year interventions for trauma and violence prevention

      Badger, Sophie; Wilkinson, Dean; Chopra, Isha (SAGE, 2024-12-27)
      Exposure to violence in early childhood is considered a public health issue and is a significant predictor of becoming a victim or perpetrator of violence later in life. There has been a significant increase in violence intervention and prevention programs that are available for children and young people; however, there are few evidence-based interventions for younger children. This review systematically explores the existing impact evidence for available intervention and prevention programs targeted at young children (ages 3-8) across the United States and United Kingdom. It also explores the feasibility and methodological issues faced with school-based prevention work. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, six electronic databases were systematically searched. Of the initial 766 articles, 13 met the final inclusion criteria. The findings showed that early intervention programs for vulnerable children can promote prosocial behaviors and protective factors. Outcomes included improved academic achievement, implementation of Social Emotional Learning-based learning, decrease in violence and criminal justice-related outcomes, and increased resiliency and emotional development among children. Evidence also showed that trauma-informed training for staff and teachers can increase teacher awareness of trauma and the importance of trauma-informed practices. Most programs showed a positive change in children as a result of early intervention programs. We discuss important issues for policy and practice in early years teaching, particularly for high-risk populations, and the importance of trauma-informed practices in the long-term, public health approach to violence prevention and reduction. We also highlight important areas for future research on violence prevention programs.
    • Corporate egoism: an investigation of business ethics in the South-Western Nigerian banking industry

      Adisa, Toyin; Babalola, Mayowa T.; Mordi, Chima; Sani, Kareem Folohunso; Adekoya, Olatunji; Harrison, Michael (Elsevier, 2025-01-08)
      The normative theory of ethical egoism has been widely applied in management studies, and there is an increasing number of organisations subscribing to its core tenet of best interest and self-interest. Using ethical egoism and ethical impact theory, this article examines the reality of business ethics and ethical professionalism in the Nigerian banking sector by focusing on the different targets set by banks for their employees and the impacts thereof on their work and non-work lives. We present the findings of interviews with 47 present and past bankers in Nigeria, and these findings suggest that banks use egoism to set and ethicise unreasonable loan and deposit targets for their workers. Our findings further indicate that the pressure and consequences of not meeting these targets have forced many bankers to engage in various forms of unethical behaviour, such as bribery and ‘corporate prostitution’. We explain how bankers’ work-life balance and health are negatively affected in the contemporary banking workplace, in which organisational wellbeing is valued above employees’ wellbeing. This article makes a unique and original contribution to the study of corporate egoism and its associated implications in the global South.
    • A novel reflective material coated polyurethane resin-based porous composite paving material for mitigating urban heat island effect

      Wanniarachchi, Chameekara; Singh, Manpreet; Bari, Klaudio; Bock, Marina; Harvey, Stuart; Arjunan, Arun (Taylor & Francis, 2025-01-03)
      Increasing urban temperatures due to the urban heat island effect and global warming have become a significant concern around the world. As urban areas grow, they often replace naturally permeable materials with impermeable ones, contributing to the urban heat island effect, and raising temperatures by 1 to 3°C annually. This study proposes a solution in the form of a novel resin-based composite paving material that is permeable, reflects sunlight, and maintains flexural strength. The composite consists of natural stone aggregate, recycled plastic, recycled rubber, and polyurethane resin. Testing revealed a flexure strength range of 2.46–2.8 MPa suitable for moderate loads. Optimal proportions featured equal volume percentages of stone aggregate, plastic, and rubber at 0.07 g cm−3 of polyurethane resin offering a 27% porosity aiding water drainage. The porosity analysis conducted on the resin-based composite paving sample using X-ray tomography data found a total porosity of 27.14%, indicating the volume of voids present within the material composed of 26.43%, connected porosity and 0.71% isolated porosity. Anti-skid tests confirmed excellent pedestrian safety with pendulum test values above 35 PTV. Coatings such as glass beads, epoxy white paste, and aluminium powder were explored to enhance reflectivity. Aluminium powder-coated pavement achieved the highest Albedo index of 0.096353, 101.7% more reflective than the reference, surpassing glass bead and epoxy white paste coatings. This innovative paving material addresses urban heat island concerns while offering safety and enhanced reflectivity for public walkways.
    • Formalization: optimizing its principles for improving small-scale gold-mining

      Ogan, Deinsam Dan; Moses, Tochukwu; Yenneti, Komali (University of Wolverhampton, 2024-07-13)
      For years, the worldwide gold mining sector has grappled with environmental and social issues, particularly evident in the small-scale operations which are predominant in developing nations. This research examines the incorporation of “Mining Formalization” into a framework for small-scale gold mining, with the goal of suggesting methods that could bolster environmental conservation and social accountability. Concentrating on developing countries where small-scale mining significantly influences local economies, this study investigates the customization of formalization principles to diminish human and environmental harm, by advocating for ethical regulatory frameworks and standards, fostering community development, and achieving the advancement of enforcement and oversight. Employing a multidisciplinary approach, this study adopts a single source systematic search (4S) strategy for its methodology. It then reviewed and integrated geological, environmental, social, and economic viewpoints to frame a holistic set of recommendations that can create significant positive changes when applied as an optimized set of Formalization Standards. Thus, by tackling specific challenges encountered by small-scale gold ventures, this investigation now offers practical insights and advice for policymakers, mining communities, and industry players that can be adopted to cultivate a more sustainable and socially accountable path for small-scale gold mining in developing nations. Envisaging a future where small-scale gold mining can contribute as a positive force for both environmental and local community welfare, this research also endeavoured to optimize its advantages, aligning them with global happenings that are tending toward responsible resource extraction.
    • Achieving sustainability in civil engineering projects in Nigeria: a case for climate change

      Daudu, Bankole; Zakharova, Julia; Daniel, Emmanuel Itodo (CITC, 2025-12-31)
      This paper investigates the nexus between infrastructure and climate change in Nigeria, particularly amidst rapid urbanization. Employing a qualitative methodology, the study delves into industry perspectives, prevailing sustainable practices, and recommendations through in-depth interviews with ten seasoned professionals spanning Nigeria's six geopolitical zones. Study findings underscore a growing awareness of climate change, manifested through tangible impacts like flooding, heatwaves, loss of livelihood, biodiversity loss, desertification, and health repercussions. However, a noticeable knowledge gap persists, particularly concerning the implications for the built environment. Encouragingly, participants are already incorporating certain sustainable practices such as green land conservation, renewable energy, and low-carbon materials, albeit predominantly in highway and building projects. The study highlights an urgent imperative to expedite the construction industry's shift toward climate-conscious practices. This necessitates robust interventions encompassing awareness campaigns, legislative measures, incentives, and fostering public-private collaboration. The study underscores that as Nigeria progresses towards its infrastructure development ambitions, overlooking the sector's environmental implications risks exacerbating emissions.
    • The use of gamification in safety training for construction workers: evidence from Lagos State, Nigeria

      Akinborode, Azeez; Daniel, Emmanuel Itodo; Akaiku, Lucy Achobe (CITC, 2025-12-31)
      Gamification has a long-term effect on safety training for workers based on the lasting impact on memory and retention through simulation and inclusiveness in training activities to check of safety measures on-site. While the knowledge and application of gamification continually expands as a training measure in the construction industry, its application in Nigeria is still largely understudied. Therefore, this study investigates its use in safety training measure amongst construction experts within the context in Lagos State Nigeria. The study revealed that the application of gamification in the construction industry is beneficial for employees in the construction field as it enhances efficiency in operations and task delivery. The design method of research adopted is the quantitative methodology which considers the positivist method to ensure that the numerical data in research in general is scientific and analyzed with scientific tools and approaches. 0.839 Cronbach's Alpha score reliability test was applied to data and 0.839 score was achieved which shows high level of data reliability. The study found that the knowledge on gamification in the construction industry is Nigeria is higher among the high-ranking experts involved in training activities who are responsible for encouraging firms to adopt this approach as an effective training tool. Although the lower ranking experts who are more exposed to accident hazards are knowledgeable in theoretical safety training, hence, the call for gamification to be included as training tool for all employees due to its associated benefits in enhancing efficiency since gamification is seen to be an effective addition to safety training in construction. The implication of this study is the revealed opportunities to tailor gamified training to specific roles and associated hazard on project sites which could further influence safety regulations and training requirement in the construction industry.
    • Offsite manufacturing for housing in emerging economies: An evaluation of current implementation levels

      Dimka, Nenpin; Gyoh, Louis; Daniel, Emmanuel Itodo; Momoh, Job (University of New Brunswick, 2024-04-26)
      Housing supply is at critical limits globally despite being enshrined as a fundamental human right. The implication of this remains nearly oblivious to fostering adequate supply. Compounding that is the added quality requirement for housing to be climate resilient. Offsite manufacturing has been identified as a viable solution to increase the supply of climate-resilient housing; however, there is a contextual gap as implementation in Emerging Economies (EE) where population growth and urbanization are rapidly occurring is less represented in literature. Additionally, while offsite manufacturing is rooted in prefabrication, an evolution of its use in EE is less documented. This study employs a quantitative methodology through a survey questionnaire of 68 construction professionals operating as Small and Medium Enterprises (SMEs) in the housing sector in a typified EE. Participants were selected using stratified random sampling across demographic variables. The study provides insights into technology adoption and design for manufacturing, which show limited adoption of contextual offsite-enhancing technologies. However, other vital aspects crucial to the increased adoption of offsite processes, such as supply chain relations between stakeholders, are established, albeit with room for improvement to attain strategic partnerships. This study's findings suggest a pragmatic approach - leveraging current practices as a starting point and formulating a roadmap for gradually integrating more sophisticated OMPs over time. Further, it contributes to a deeper understanding of how offsite manufacturing can be harnessed to enhance the efficiency and sustainability of housing construction in EE, thereby advancing climate-responsive housing development in these regions.
    • Closing the housing gap in the UK: A preliminary study of using the offsite construction approach on Brownfield site

      Akaiku, Lucy Achobe; Daniel, Emmanuel Itodo; Pathirage, Chaminda; Heesom, David; Chinyio, Ezekiel (CITC, 2025-12-31)
      The housing shortage in the UK has remained a prevalent and pressing issue, prompting a need for innovative and sustainable solutions. One contributing factor to this is limited availability of land, including brownfields sites. The offsite construction (OSC) approach has been recognized as a viable and eco-friendly solution to addressing the issue, yet its potential on brownfield site (BFS) remains largely unexplored. Prior research of literature suggested that integrating OSC on brownfield site has the capacity to support housing supply , while addressing some of the challenges of developing on BFS. A focus group discussion was conducted to establish industry opinion on the factors militating against the wide adoption of OSC approach on BFS for housing development despite the promises both concepts hold to support sustainable housing delivery. The study found that the UK government actively promotes BFS redevelopments and OSC approach to achieve sustainability goals, protect the greenbelt, and mitigate the housing crisis through policy and financial instruments. The study further grouped the findings of adopting OSC approach on BFS under process, human impact and sustainability. The result contributes to the literature by promoting the integration of OSC approach and BFS development and offer valuable insights for policymakers on the efficiency and effectiveness of government support instruments in relation to OSC and BFS for sustainable housing solutions.
    • Novel scent enrichment enhances socio-sexual and olfactory behaviors in zoo-housed gentle lemurs

      Fontani, Sara; Glendewar, Gale; Cowen, Rachel L.; Callagan, Georgia; Costantini, Anna Beatrice; Elwell, Emily Jayne; Dubreuil, Colin; Palframan, Matthew; Vaglio, Stefano (Wiley, 2024-12-18)
      The Alaotran gentle lemur (Hapalemur Alaotrensis) is one of the most endangered primates in the world and shows a low success rate in captive breeding programmes. We tested a novel scent enrichment, made up of a synthesized mixture likely conveying information about female fertility, on four unsuccessful breeding pairs (n = 8 subjects) living at the Jersey, Birmingham, London (United Kingdom) and Mulhouse (France) zoos. We evaluated the effects of the scent enrichment on behavior (515 h of observation) and fecal endocrinology (cortisol and testosterone measurements) (n = 180 samples) comparing pre- enrichment, enrichment and post- enrichment phases. We found a small effect by sex on olfactory behaviors related to the enrichment. We also found that both male and female sexual behaviors significantly increased during the enrichment. Conversely, we did not find any significant change related to enrichment in cortisol and testosterone levels, whilst some effect by the zoo environment. Our results show little effectiveness by the scent enrichment as the lemur hormone levels did not change significantly and the lemurs continued to fail to reproduce following the enrichment. Nevertheless, our findings highlight that biologically relevant scent may trigger natural species-specific behaviors, with potential implications for enhancing behavioral health and management of zoo-based endangered lemur species.
    • Wave goodbye to the future: Haunting, music, and cultural stasis in the regional novels of Catherine O’Flynn and Joel Lane

      Francis, Robert; McDonald, Paul (Taylor & Francis, 2024-12-02)
      Using Mark Fisher’s reconfigurations of Derrida’s Hauntology, this article explores the interactions between these narrative features in the works of Catherine O’Flynn and Joel Lane. Fisher reworks hauntology in relation to the distinct features of ‘futuristic’ music and ‘retro’ perceptions of what lay ahead. He links this psychic and cultural trap with ideas of the weird and the eerie. Both O’Flynn and Lane have produced eerie texts set in the off-kilter and marginal West Midlands regions, placing their characters in literal and symbolic haunted sites. Their respective spectres – people, places and cultures – are caught in a perpetual liminality and psychic looping: a hauntological position. These play out through the motifs of melancholic landscapes, personalities and cultural currents, most notably in music. This article interrogates these strange conjugations and interfaces that play out in the fiction of O’Flynn and Lane.
    • Gambling harms, stigmatisation and discrimination: A qualitative naturalistic forum analysis

      Penfold, Katy; Nicklin, Laura Louise; Chadwick, Darren; Lloyd, Joanne; Perales, José C (Public Library of Science (PLoS), 2024-12-10)
      People who experience gambling harms commonly experience stigmatisation, which is detrimental to psychological wellbeing, and a significant barrier to help-seeking. While there have been efforts to challenge stigmatisation, there is little empirical evidence available to inform such initiatives. To address this gap in knowledge, we conducted a thematic analysis of naturalistic data in the form of posts made on online support forums by people with experience of gambling-related harm, in order to understand how they are stigmatised, and to identify barriers to help-seeking. Five main themes were identified: (a) beliefs about the nature and origin of gambling addiction, which related to participants’ beliefs about causes of gambling harm and cognitions about the nature of addiction; (b) self-stigma, which encompassed the frequent and substantial incidences of self-stigma; (c) anticipated stigma, which described the stigma and discrimination people expected to face because of their gambling harm; (d) stigmatising other people who experience gambling harm, which describes the ways in which some people who experienced gambling harms stigmatised other people who experienced gambling harms; and (e) experienced stigma and discrimination, which encompassed the experienced stigmatisation people encountered. Experiences discussed/described within the forums were developed into a timeline of gambling harms which was cyclical in nature and involved six stages: onset, concealment of problems, crisis point, disclosure of problems, recurrence of harms (sometimes termed ‘relapse’) and recovery. The study highlights the impact of societal stigma on individuals’ self-perception and interactions, particularly emphasising the challenges experienced during relapse periods, which heighten stigma and distress. The study also identifies potential avenues for stigma reduction, including targeted campaigns addressing societal, anticipated, and self-stigma.
    • Attitude and knowledge about electroconvulsive therapy among trainee doctors and psychiatrists: A survey before and after a training session

      Kar, Nilamadhab (Wolters Kluwer – Medknow, 2024-10-28)
      BACKGROUND: Electroconvulsive therapy (ECT) is a safe and effective treatment in psychiatry, but its use is decreasing. AIM: It was intended to evaluate the attitude and knowledge among psychiatric trainees and psychiatrists and any change following a training session on ECT. MATERIALS AND METHODS: A survey was conducted in a teaching psychiatric hospital before and after a training session on ECT using questionnaires on attitude, knowledge, and clinical scenarios for prescribing ECT. RESULTS: This study suggested that the majority of trainees and psychiatrists had positive attitudes and appreciable knowledge base regarding ECT. There were uncertainties in a few areas, such as ECT for treatment-resistant depression without risk of self or others, treatment-resistant schizophrenia, patients with no mental capacity, and those who refuse to consent. The change following the training session was more prominent in prescribing scenarios. In other areas, the change was marginal, probably because of the ceiling effect. CONCLUSIONS: While psychiatrists and trainees maintain positive attitude and appreciable knowledge about ECT, it is essential to remain aware of recent advances and guidelines about ECT through training to continue prescribing it appropriately.

Hence, they are favorable for many human health applications, such as, tissue engineering, tissue healing, soft biomedical implants, drug delivery, etc., Recently, bioprinting was used for alginate-based biomaterials to enable the precise fabrication of constructs with customized shapes and enhanced functionality. This chapter reviews the recent developments in 3D-printed alginate-based hydrogels, focusing on rheological characteristics, mechanical properties, and biological performance and highlighting their prominent role in addressing healthcare challenges.
    • Personality dimension, suicidal intent, and lethality: a cross-sectional study of suicide attempters with or without personality disorders

      Sahoo, Amruti; Swain, Sarada Prasanna; Kar, Nilamadhab (SAGE, 2024-11-15)
      Background: Although personality disorders (PD) are known risk factors for suicide attempts, studies on personality dimension are scarce, which may provide further insights for interventions. Methods: The relationship between personality dimension, lethality, intent, and quality of life (QOL) was studied in suicide attempters with or without PD. We used the international personality disorder examination (IPDE) dimensional score, the scale for assessment of lethality of suicide attempt (SALSA), suicide intent scale (SIS), and WHOQOL-BREF QOL scale, to assess a sample of suicide attempters admitted to a general hospital. Results: PD was present in 43.2% and 57.9% of them had more than one PD. Comparison of attempters with or without PD suggested that the lethality of attempts and QOL were comparable, whereas self-reported suicide intent was significantly low in patients with PD. A higher proportion of PD patients reported relational problems as the reason for the attempt. The personality dimensional score was significantly higher for female attempters from urban backgrounds than for those with previous attempt histories. It was negatively correlated with the lethality of attempts and suicide intent. Conclusion: It is important to explore the personality dimension of the suicide attempters, along with PD, that may highlight additional risks and suggest the need for specific support.
    • Coping strategies used by children and adolescents following disaster trauma: A review of associated factors and intervention options

      Kar, Nilamadhab (Wolters Kluwer – Medknow, 2024-10-28)
      Children and adolescents are more vulnerable to disaster-related trauma. The specific aim of this paper was to review the coping strategies used by children and adolescents in the aftermath of disasters. The relationship of coping methods with psychological consequences were also explored, along with the effectiveness of specific strategies in dealing with traumatic experiences of disasters. A literature search of electronic databases, involving the keywords “coping,” “children” and “adolescents,” and “disaster” was done along with secondary searches of the cross references. It was evident that children and adolescents use a range of coping strategies, and a large proportion of them are helpful, while others could be detrimental to their mental health. Many children and adolescents cope with disaster trauma and are resilient. Facilitation of positive coping methods can be used as an intervention along with other supportive activities and as a part of other psychological interventions. Coping can be supported by family, nonprofessional caregivers, community, and clinicians. There is a research need to develop consensus about the terminologies and culture-specific coping assessments and to explore the short- and long-term effectiveness of interventions focused on coping.
