Measuring Children’s Actual Exposure to Unhealthy Food Marketing in (and With) Digital Media: A Narrative Scoping Review
No full textThis review aimed to identify and evaluate methods to measure children’s actual exposure (marketing that actually reaches children) to food marketing in digital media. Monitoring actual marketing exposure in digital media is challenging. It is delivered via complex, data-driven, personalized systems to children’s personal devices—so viewing this presents privacy and methodological challenges. Digital marketing monitoring therefore often instead assesses potential exposure (marketing that children are likely to encounter in their usual digital places). Yet, measuring actual exposure is essential for policy development, enforcement, and research. We searched for eligible articles published during 2000–2024 using free-text searches combined with database thesauruses in Academic Search Complete (EBSCOhost), Ovid Medline, CINAHL (EBSCOhost), PsycInfo (EBSCOhost), and Scopus. A horizon scan, gray literature search, and consultation with experts were also performed. Data extracted were (1) type of method and tools, (2) how the method captures data, (3) challenges and limitations, (4) researcher burden, (5) recruitment and retention, (6) privacy, and (7) food marketing definitions and nutrient profiling system applied. We identified 25 sources (reporting on 16 studies) and grouped these into 4 methods clusters, each with different attributes and limitations: screen capture, where participants’ device screen is recorded while they use it; wearable cameras, which capture participants’ exposure to all marketing across a day; screenshots of self-identified marketing captured by participants themselves; and automated extraction of paid advertising metadata using software installed on participants’ devices. Screen capture is currently the optimal method. No identified method is straightforward: all carry a heavy data management and analysis load and involve trade-offs of validity, ease of use, privacy, and overall cost. Capturing children’s screens with currently available tools is challenging, but the benefits are clear, as identifying children’s actual exposure to harmful marketing in digital media is essential
Navigating Organisational Contexts as Women Leaders
No full textThis chapter explores the complex realities of women leaders, with particular attention to Global Majority (GM) women navigating Eurocentric organisational structures and alternative feminist spaces. Drawing on two distinct yet interconnected case studies—an empirical study involving 22 GM women leaders across sectors and an oral history project with Bristol Crisis Service for Women—the chapter interrogates how racialised and gendered dynamics shape leadership identities, opportunities, and resistance. Using critical feminist and Critical Race Theory (CRT) lenses, the authors identify four historical tropes—Sapphire, Jezebel, Black Mammy, and Queen of Sheba—that continue to influence the perceptions and treatment of GM women leaders in mainstream settings. These tropes, often internalised and institutionally embedded, contribute to organisationally induced trauma and stress (OiTS), silencing, and hyper-surveillance.
The chapter further examines how women challenge these dominant narratives through relational leadership and peer support, offering counter-narratives of resistance, care, and community. The Bristol Crisis Service for Women exemplifies how grassroots, women-only peer support structures can disrupt the re-traumatising tendencies of mainstream mental health services and promote relational safety. Throughout, the authors highlight the critical role of insider/outsider identities and advocate for leadership models rooted in reciprocity, solidarity, and psychological safety. Implications for social work practice are outlined, with a call for anti-racist, feminist-informed, trauma-aware leadership that values women’s agency and lived experience
Upper limits of CH<sub>4</sub> and OCS in the Martian atmosphere from NOMAD/TGO solar occultation: A study of vertical averaging and systematic uncertainties
No full textHere we update the search for two trace species of high interest in the Martian atmosphere, methane (CH4) and carbonyl sulfide (OCS), using solar occultation (SO) measurements from the NOMAD spectrometer on board the Trace Gas Orbiter (TGO). Neither species has been detected in previous analyses of TGO’s dedicated SO instruments, ACS and NOMAD. Our approach focused on NOMAD-SO data, assessing in detail the calibration uncertainties to quantify systematic error components, and investigating if vertical averaging of spectra to reduce random noise would enhance the signal-to-noise ratio (SNR). The latter step required careful data cleaning with precise radiative transfer modeling and should improve upon earlier searches that analyzed spectra individually.
We examined 19,330 NOMAD SO spectra targeting CH4 and OCS, from diffraction orders 134 and 129, corresponding to 76 and 142 vertical scans, respectively. These scans span a wide range of latitudes and seasons over three Martian years (April 2018 to November 2022, MY34-MY36). No CH4 or OCS absorption features were detected and our composite vertical profiles (5–50 km tangent altitude) yielded stringent upper limits. For methane, the 1-σ upper limits typically lie around 0.5 ppbv, reaching 0.2 ppbv at some altitudes and locations. Our methane limits were primarily constrained by systematic uncertainties, particularly the residual baseline shape, and are therefore relatively higher than those previously reported in Knutsen et al. (2021), who processed the spectra differently to remove this effect. For OCS, our composite profiles indicate concentrations below 5 ppbv at low altitudes and below 2 ppbv in some cases, also at the 1-σ significance level.
Further improvements will require additional calibration refinements, ideally through better characterization of instrument behavior under thermal variations. As a practical step, narrowing the analyzed spectral intervals can reduce continuum uncertainties, provided contaminating features are absent. For methane features in diffraction order 134, such narrowing lowers uncertainties by a factor of three, getting closer to the most stringent limits previously reported (Knutsen et al., 2021)
Exploring the prevalence, forms, risk factors, and interventions associated with violence against children in alternative care settings: A scoping review
No full textViolence against children (VAC) in alternative care settings, including foster care, residential care, and kinship care, is a significant global concern. This scoping review synthesises evidence from 77 studies published between 2014 and 2024 across high, middle, and low-income contexts, examining the forms, risk factors, consequences, protective features, and interventions associated with violence in care. In line with PRISMA-ScR guidance, the review maps patterns in the evidence base but does not estimate pooled prevalence across settings.
Neglect was the most frequently reported form of maltreatment, often linked to poverty and limited external support, including in some informal kinship care contexts. Residential settings were commonly associated with reports of physical abuse and peer violence, while findings on sexual abuse varied across contexts. Emotional abuse was reported in all care settings.
Identified risk factors included placement instability, inadequate caregiver support, poverty, and prior exposure to violence. Reported consequences ranged from poor mental health and disrupted relationships to heightened risks of revictimisation. Evidence on effective interventions was sparse, although supportive caregiver-child relationships and trauma-informed models were noted as protective.
Important gaps remain in longitudinal and disaggregated evidence, particularly in low and middle-income contexts and with respect to peer violence, children with disabilities, and LGBTQI+youth. While this review focuses on violence, it is essential to caution that many children experience alternative care as protective and nurturing, and our findings should not be interpreted as suggesting that all care arrangements are harmful. Strengthening family-based care, ensuring robust oversight, embedding protective, child-centred practices, and prioritising reintegration where possible are critical to reducing risks and promoting children’s well-being
Investigatng the Role of Calcium Signalling Genes in the Progression of Neuroendocrine Prostate Cancer
No full textProstate cancer (PCa) can manifest as a multi-stage, incurable, progressive malignancy called NEPC (Neuroendocrine PCa) that may not respond to established therapeutic interventions. This project aims to understand the role of cell-signalling genes in the progression of NEPC. Using the OMIM database, we identified 3708 cell-signalling genes. Of these genes, 200 were significantly upregulated in a clinical dataset comprising gene expression data from 15 NEPC and 34 prostate adenocarcinoma patient samples. A pathway analysis on differentially expressed genes indicated calcium ion transport was the most highly upregulated signalling modality in NEPC versus prostate adenocarcinoma. Calcium imaging experiments reported a significant alteration in intracellular calcium signalling in response to ATP-stimulation in prostate adenocarcinoma versus NEPC cell lines. Expression of the 12 upregulated calcium ion transport genes was analysed using RT-qPCR and western blotting in a panel of human and murine PCa cell lines. Our data showed an upregulation of ANO6, a calcium-activated chloride channel, in human and murine NEPC cell lines, aligning with our bioinformatics result. ANO6 was also overexpressed in hypoxia-induced transdifferentiated LNCaP cells. Although it has not been previously studied in NEPC, ANO6 drives proliferation and migration in other cancers. We used benzbromarone, a pharmacological inhibitor of ANO6, to study the functional role of ANO6 in NEPC cells. High concentrations inhibited NEPC cell proliferation, while clinically relevant doses significantly reduced cell migration in a wound healing assay. Ano6 knockdown using siRNAs confirmed that ANO6 mainly affects NEPC cell migration and not proliferation. Single-cell RNA sequencing in patient samples revealed higher ANO6 expression in the endothelial cells of NEPC patients than those with adenocarcinoma, suggesting a role related to the tumour microenvironment and angiogenesis for ANO6. Therefore, further exploration of the ANO6 gene offers new opportunities for targeting NEPC therapeuticall
Exploring the Determinants of Quality of Life for LGBTQ + People: Findings from UK Participants in the Global Pride Survey
No full textIntroduction: Despite recent initiatives to understand and respond better to LGBTQ+ lives in the UK, there remains a lack of detailed knowledge about the needs and experiences of the LGBTQ+ population at an everyday level, including drivers of quality of life, and its association with mental health.
Methods: This paper draws on findings from the UK dataset in the Global Pride survey collected in 2022. Data from 172 individuals aged 19-77 from diverse sexual and gender identities were used to identify and explore the determinants of quality of life at the intersection of both sexual orientation and gender identity.
Results: The study identified differences in quality of life and mental health across sexual identity groups. Bisexual women reported higher quality of life than other groups, while sexual diverse individuals and bisexual men experienced greater depressive symptoms. Income, general health, and social support were also important factors associated with quality of life.
Conclusions: As a preliminary study, we illustrate the potential future use of intersectionality in gaining a more nuanced approach to understanding the different drivers and differences in the LGBTQ+ population and the value in promoting mixed methods research to understand better the quality of life amongst LGBTQ+ communities. We highlight theories of liveability to expand our understanding beyond individual and structural factors that cause minority stress.
Policy implications: Evaluation of how effective UK equalities laws and policies are in protecting LGBTQ+ people from discrimination and the areas of policy needed to develop and improve their lives requires improved data collection and their use in monitoring and application through an intersectional approach. Nuanced and focused policymaking could allocate resources that addresses health and wellbeing within its wider context and engage the LGBTQ+ community to look beyond known factors of exclusion towards identifying what helps people to survive and thrive
Alerting and orienting attention in anti-predator vigilance: neurocognitive modelling and behavioural evidence
No full textField manipulations of perceived predation risk are frequently used to interpret changes in gaze shift patterns between foraging and anti-predator vigilance. Gaze shifts relate to spatial attention mechanisms studied in psychophysical and neuroimaging laboratory studies. However, connecting laboratory-based insights to naturalistic contexts involving predation risk remains challenging. To bridge this gap, we developed a study of Florida scrub-jay sentinels (Aphelocoma coerulescens). Sentinel bouts exclude foraging, providing a simplified focus for studying attention in the wild. We first defined a neurocognitive agent-based model. For initial model validation, we manipulated background predation risk in simulations, which produced head rotation behaviour consistent with empirical literature. We then conducted an experiment both in the field and in computational simulations based on the model. In the field experiment and its simulation, we manipulated perceived acute predation risk and measured a decrease in head rotation frequency. The model suggests that greater background risk requires more frequent head rotations to enhance predator detection, whereas greater acute risk requires more observations of fine-grained (possible) predator locations per head position. This shift from detection to localization is consistent with a shift from alerting to orienting attention. Our approach demonstrates a promising path for integrating ecological field experiments with laboratory-based comparative (neuro)cognition research
Figures of Liminality and Transgressors of Limits and Borders: the <i>Trickster</i>, the <i>Uncanny</i>, and the <i>Spiritus Mercurius</i>. A Dialogue between Anthropology, Cultural Psychology and Psychoanalysis
No full textThe article explores the Trickster as a symbol of liminality, transgression, and creativity, analyzing its characteristics through mythology, folklore, and literature. The Trickster (a prankster and a “boundary-crosser”) embodies ambiguity, deception, and hidden wisdom, operating at the intersection of order and disorder, of sacred and profane. Through myths such as that of Hermes, as well as the tales of fools, jesters, and clowns, the Trickster is portrayed as an agent of transformation, subversion, and innovation. It subverts social and cultural categories through play, irony, hyper-sexualization, and the absence of shame. Turner’s theory of liminality and Freud’s notion of the uncanny are compared to highlight how the Trickster traverses both psychosocial thresholds and the boundaries between consciousness and the repressed—generating ambiguity, anxiety, and estrangement. The Trickster’s archetypal function, as elaborated by Jung, is expressed as both a collective and personal shadow—a symbol of productive chaos and unconscious creativity. This figure proves essential for understanding processes of cultural and psychic change, acting as a catalyst for innovation and symbolic renewal. This article emphasizes the importance of the Trickster as a symbol of psychic and collective processes of innovative adaptation, creativity, and transformation. But at the same time, the Trickster points to the associated risks of disorientation, unease, subversion and suffering. Through this ambivalence, the Trickster provides insights for interdisciplinary inquiry across cultural psychology, anthropology, and psychoanalysis
Book Launch : Examining Stereotypes and Parenting Behaviours of South Asian Heritage Parents: Discourse and Case Studies
No full textThe Book Launch was organised by the the Centre for Global Challenges and Social Justice (GCSJ) inviting global audience for the discussion and showcasing of the book content and related conversations.
Examining Stereotypes and Parenting Behaviors of Asian Heritage Parents: Discourse and Case Studies offers a pioneering solution to this problem. It represents a ground breaking initiative to break free from the constraints of traditional research methodologies and provide an unfiltered, in-depth look at the real narratives of South Asian parents in the UK. By weaving together the psychological, emotional, social, and cultural dimensions of parenting, this book uncovers a holistic view of this complex journey, one that transcends the limitations of sociology, psychology, or cultural studies. It does not aim to solve problems but rather seeks to capture authentic "family stories" and parenting experiences directly from the voices of the parents themselves
Categorisation and Assimilation-Contrast Theory Explaining Loss of Trust after an Alleged Corporate Misconduct
No full textThere is a limited understanding of how information about a negative event is used by customers when deciding whether to continue to trust a company (a key aspect of reputation management) and how the same information can result in different choices by individuals. To meet this gap, the aim here is to test the predictions from categorisation theory and assimilation contrast theory and to add to our theoretical understanding of trust loss. A moderation model of survey data (n=410), a cluster analysis and a content analysis of explanations given are used to test hypotheses.
The work demonstrates that a reaction to a potential trust violation involves two stages: a decision on responsibility, followed by an evaluation of the significance of the misconduct. If a trusted supplier is not held responsible, the typical customer will not re-categorise the supplier as not trusted. If they are held responsible, the typical customer may re-categorise the supplier as not trusted depending on how significant they believe the misconduct to be
