The Influence of Family on Gambling Behaviours : A Rapid Review of Emergent Literature
(2026-06) Smith, Jessica; Wright, Simon; Dighton, Glen; Dymond, Simon; Torrance, Jamie; Department of Psychology
The influence of the family on gambling behaviours has been widely explored. However, findings remain inconsistent, and with family structures evolving, updated evidence is needed to guide prevention strategies. A rapid review of empirical studies (2018–2024) explored the influence of the family on gambling in childhood and adulthood. Thirty-six studies, predominantly from the USA, revealed that families significantly impact gambling behaviours through two perspectives: Family Environment in Childhood and in Adulthood, respectively. Gambling may become normalised within families, and increase risk for gambling-related harm, compounded by factors such as parental relationships, income, violence, and maltreatment. Conversely, families can mitigate gambling-related harm through family-oriented interventions. Recent research on the interplay between families and gambling remains limited. Addressing this gap is crucial for developing effective harm-reduction strategies and family-based therapies. Future research should prioritise understanding the complexities of family influence on gambling behaviours.
The relationship between mental toughness, rumination, and depressive symptoms in athletes : A preliminary cross-sectional study
(2026-07) Tahtinen, Richard E.; Jónsdóttir, Sara Björk; Kristjánsdóttir, Hafrún; Department of Sport Science
AbstractResearch has shown that mental toughness (MT) may be a protective factor for depressive symptoms, however, we know little about how this relationship may emerge. The aim of this preliminary cross-sectional study was to explore potential indirect relationships between MT and depressive symptoms via brooding and reflective rumination. A total of 113 Icelandic national team athletes participated in the study, of which 80 were women (70.8%) and 33 were men (29.2%). Prevalence of clinically significant depressive symptoms was 4.5% (5.13% females and 3.03% males), with non-significant mean differences between genders in total symptom scores. The indirect association between MT and depressive symptoms via brooding was negative, with the confidence interval excluding zero, b = -0.03, 95% CI [-0.07, 0.01]. The confidence interval (95% CI [-0.16, -0.01]), and the standardized coefficient (β_indirect = -0.08) was consistent with a small indirect association. In contrast, the indirect association between MT and depressive symptoms via reflective rumination was not supported, as the confidence interval included zero. These findings suggest that MT may be associated with depressive symptoms in part through its negative relationship with brooding rumination. These findings should, however, be considered preliminary and limited due to the relatively small sample size and cross-sectional design. We also discuss how MT may overlap with other cognitive-affective constructs and how this conceptual breadth may introduce challenges to its current applied utility. Addressing these conceptual aspects with longitudinal and experimental research would benefit future applied efforts aimed at supporting athlete mental health.
Source-separation infrastructure and the reduction of residual household waste : Evidence from Iceland's 2023 waste reform
(2026-10-30) Óskarsson, Guðmundur Kristján; Agnarsson, Sveinn; Davíðsdóttir, Brynhildur; Ingason, Helgi Thor; Department of Engineering
This study evaluates whether Iceland's 2023 waste-management reform, which combined Extended Producer Responsibility (EPR) financing with mandatory four-bin kerbside collection, reduced targeted household waste remaining in the general bin. Using a decade-long dataset (2014–2025) derived from systematic waste characterisation studies, the analysis employs a panel Interrupted Time Series (ITS) design comprising 55 observations across five analytical areas in the Capital Region to quantify changes in residual biodegradable waste, paper, plastic, and non-targeted fractions. The results indicate a statistically significant structural break in household disposal behaviour, with total waste in the general bin declining by an average of 37 % following the reform. This shift is primarily driven by a pronounced “organic transition,” as biodegradable waste remaining in the residual stream decreased by 54 %. By 2024, total apparent capture rates for paper and plastic reached peaks of 83 % and 44 %, respectively, before showing slight stabilisation in 2025. These findings suggest that the EPR framework provided an important financial and regulatory foundation, but the decisive behavioural mechanism was the rollout of accessible household-level source-separation infrastructure, especially for biodegradable kitchen waste. For paper and plastic, observed changes are more consistent with the continuation and reinforcement of pre-existing downward trends alongside improved post-reform apparent capture rates. However, the slight stabilisation in performance by 2025 is consistent with a tendency for initial participation gains to diminish over time, highlighting the importance of sustained behavioural engagement, contamination control, and complementary collection pathways for residual materials not targeted by the four-bin system.
SCAR : Mining and Structuring Smart Contract Security Audit Reports
(Association for Computing Machinery, Inc, 2026-07-17) Qasse, Ilham; Tseng, Po Yu; Hamdaqa, Mohammad; Hjálmtýsson, Gísli; Tan, Shin Hwei; Khomh, Foutse; Department of Computer Science
Smart contract security audit reports contain rich information about vulnerabilities and code quality issues in Web3 projects. However, these reports are scattered across different sources and formats, making large-scale analysis difficult. We present SCAR (Smart Contract Audit Repository), an open-source dataset and tool that automatically aggregates these audit reports. SCAR crawls reports from leading security firms (e.g., OpenZeppelin) and community contests (e.g., Code4rena), parses them into a structured JSON schema, and offers a queryable API for accessing the data. Its pipeline includes a crawler, a text-mining module to standardize findings (e.g., vulnerability types, severity, code references), and a web API for retrieving insights. With hundreds of audits covering thousands of issues, SCAR enables empirical studies of smart contract vulnerabilities at scale. The SCAR project repository is available on GitHub, and the screencast demo is available at this link.
Recruitment Strategies, Response Rates, and Non-Response Patterns in a Nationwide Registry-Based PRO Survey of Cancer Survivors and the General Population : The SURV-ICE Cohort
(2026-05) Sigurðardóttir, Kristjana; Friðriksdóttir, Nanna; Kristinsdóttir, Nanna Margrét; Kristjánsdóttir, Lára; Skúlason, Hjalti Gunnlaugur; Haraldsdóttir, Álfheiður; Alfonsdóttir, Sigríður Ása; Jóhannesdóttir, Anna Kristín B.; Birgisson, Helgi; Tryggvadóttir, Helga; Birgisdóttir, Freyja; Valdimarsdóttir, Heiðdís; Aspelund, Thor; van de Poll-Franse, Lonneke; Gunnarsdóttir, Sigríður; Department of Psychology
Background: Population-based studies using patient-reported outcomes provide important insights into health-related quality of life (HRQoL) and the long-term impact of cancer and its treatment. Declining response rates and potential non-response bias have presented methodological challenges, particularly in registry-based surveys including both cancer survivors and population controls. The SURV-ICE study was established to assess HRQoL and health literacy among cancer survivors in Iceland while evaluating recruitment processes and participation patterns in a nationwide mixed-mode survey. Methods: SURV-ICE is a nationwide, population-based cross-sectional survey conducted in Iceland in 2025. Adults diagnosed with invasive cancer between 2014 and 2024 were identified through the Icelandic Cancer Registry and invited alongside an age- and gender-matched control group sampled from national registers. Participants completed validated EORTC instruments. Recruitment used a mixed-mode strategy including postal invitations, web-based and paper questionnaires, electronic reminders via the national health portal, and targeted telephone follow-up. Results: Among 10,005 cancer survivors 5489 (54.9%) responded to the questionnaires and among 5663 controls 2297 (40.6%) responded to the questionnaires. In both groups participation peaked among individuals aged 60–79 years and was lowest among the youngest and oldest groups. Cancer survivors had higher odds of participation than controls (OR 1.84; 95% CI 1.72–1.97). Most responses followed the initial postal invitation and first electronic reminder. Data completeness was high (≥80% item completion in 95.7% of instruments). Conclusions: Nationwide registry-based recruitment for large-scale PRO research is feasible in Iceland and can achieve competitive response rates without incentives. SURV-ICE provides an infrastructure for future research on cancer survivorship, HRQoL, and health literacy.
