No full textDomestic Homicide Reviews / Domestic Abuse Related Death Reviews Coding Framework
This coding framework (codebook) provides the full set variables, operationalised definitions, categories, coding rules and decision rules used to code Domestic Homicide Reviews / Domestic Abuse‑Related Death Reviews. The code book was created for the quantitative content analysis conducted as part of the doctoral thesis project titled Domestic Homicide Reviews: An exploration into Perpetrator MH in Intimate Partner Homicide in England and Wales (March 2026).
The codebook is made openly accessible to support transparency, replicability, and consistency across the dataset
Lorentzian Regime I of Timeline-Relative Quantum Collapse (TRQC)
No full textLorentzian Regime I of Timeline-Relative Quantum Collapse develops the continuum realization of TRQC on an effective Lorentzian manifold. The discrete collapse field becomes a real scalar field, structural time becomes a dynamical scalar field, and observers are represented by a unit timelike vector field. A collapse-active domain is defined where structural time is physically valid and collapse roughness and shear satisfy fixed thresholds.
The paper introduces a structural time sector Lagrangian, corresponding field equations for structural time evolution, and a covariant collapse equation including observer coupling. The projection domain is expressed in invariant geometric form, and structural aging along observer worldlines reproduces relativistic differential aging as an emergent effect.
Regime I bridges the metric-free foundations and relativistic field theory, showing how classical spacetime behavior and observer dynamics arise within collapse-active regions of TRQC. Official project website: https://trqctheory.or
Odios juveniles. La alfabetización digital de los adolescentes ante la incidencia de la gordofobia en redes sociales.
No full textLos mensajes de odio son cada vez más frecuentes en Internet. Allí alcanzan una rápida y amplia difusión, sin que sea posible su supervisión (Nave and Lane, 2023). Constituyen un grave problema social porque humillan, denigran e incluso amenazan físicamente a una persona por formar parte de un grupo vulnerabilizado por su género, raza, ideología, diversidad corporal, entre otros rasgos específicos compartidos (Gómez, Paz, Cabeza, 2021). Preocupan especialmente los jóvenes porque constituyen una audiencia vulnerable y en proceso de formación y, además, con presencia asidua en las redes sociales. Son sin embargo muy escasas las investigaciones que abordan, en los entornos digitales, la relación de los menores con este tipo de expresiones (Calvert, 1997; Jubany y Roiha, 2018; Richardson-Self, 2018; Wachs y Wright, 2018).
Aquí se presenta un proyecto exploratorio que analizará qué capacidad tienen los menores (entre 12 y 17 años) para enfrentarse, de forma crítica y responsable, a mensajes de odio, diseminados en sus redes sociales y dirigidos a personas con obesidad (gordofobia). Este proyecto se centra en el menor como agente prosumidor que crea, comparte y consume el estigma de la gordura en redes sociales. Este estigma está tan generalizado como el racismo y el sexismo (Andreyeva et al., 2008).
Se aplicará un método mixto deductivo que se implementará en dos fases. En la primera se realizará una encuesta a 1070 menores (12 a 17 años) sobre su capacidad para mediar con este tipo de mensajes de odio y su predisposición a desafiar estas narrativas. Se analizará su aptitud a tres niveles: cognitivo, crítico y ético. En la segunda fase se propone un análisis de discurso en redes sociales. Pretende localizar, definir y categorizar la tipología de mensajes de odio y las narrativas dominantes de la gordofobia, presentes en los canales y cuentas de creadores de contenido que habitualmente consultan los menores.
Lo relevante de este proyecto es poder transferir a padres, tutores y educadores qué aspectos son fundamentales en la atención y supervisión del menor referidos a la supervisión de contenidos en las redes sociales y a la mediación parental y/o social en los mismos. Además, ofrecerá unos primeros resultados que permitirán plantear unas estrategias de intervención para fomentar la alfabetización digital crítica y ética de los menores. Es importante igualmente para la sociedad en general, porque facilitará una convivencia más inclusiva

Scientific Content Analysis and Deception Detection: A Systematic Review of the Empirical Literature
No full textBackground: Scientific Content Analysis (SCAN) is a verbal credibility assessment method used by law enforcement agencies worldwide to identify deception in written statements. Despite its widespread practitioner adoption, the empirical validation of SCAN remains contested. This systematic review synthesizes the peer-reviewed literature on SCAN and related content-based deception detection methods identified through a PRISMA-guided search of Scopus, Web of Science, and Google Scholar.
Methods: A three-database search retrieved 591 Google Scholar results, 12 Scopus records, and 13 Web of Science records. After removing duplicates, non-peer-reviewed sources, books, theses, reviews, and irrelevant items, 37 empirical and applied studies were retained for analysis. Literature reviews and meta-analyses were used exclusively for theoretical framing.
Results: The empirical record consistently shows that SCAN in its classical form performs at or near chance level for distinguishing truthful from deceptive statements. Inter-rater reliability is low except for pronoun use. Practitioners nonetheless report high confidence in SCAN. Adjacent methods, including Criteria-Based Content Analysis (CBCA), Reality Monitoring (RM), the Verifiability Approach (VA), and automated Natural Language Processing (NLP) tools, show more robust validity, though effect sizes remain modest. Cross-linguistic and cross-cultural applications reveal that several core verbal deception indicators are partially transferable across languages, with necessary contextual adaptation.
Conclusions: SCAN should not be used as a standalone veracity assessment tool in criminal proceedings. However, specific criteria, notably pronoun use, denial structure, and missing information, retain investigative utility when used as interview preparation tools rather than as lie detectors. Future research should prioritise standardised rubrics, cross-validation procedures, and real-crime corpora
NetPsy: An Open-Source Interactive R/ShinyWeb Application for Undirected Psychological Network Analysis
No full textPsychological network analysis has gained considerable attention in the last years, yet the requirement of R programming still excludes many potential users. We present NetPsy, a free and open-source R/Shiny web application that wraps the full pipeline of undirected network analysis behind a graphical interface, from data import through automated reporting. Users can upload CSV or Excel files, run Goldbricker redundancy checks (which flag item pairs that may be too similar to distinguish empirically), and estimate networks for continuous data (Gaussian Graphical Models with EBICglasso or ggmModSelect), binary data (Ising models), or mixed data (mgm). The application computes standard centrality indices such as strength and expected influence, together with bridge centrality measures relevant to comorbidity research. Bootstrap routines provide case-dropping CS coefficients and nonparametric confidence intervals for edge weights. Group comparisons rely on the Network Comparison Test, reporting invariance statistics for network structure (M), global strength (S), and individual edges (E) with Holm correction. Visualization uses Fruchterman–Reingold layouts with adjustable parameters, and an optional module generates DOCX reports assisted by large language models. We illustrate these capabilities with simulated data and compare NetPsy against JASP Network and direct R scripting in terms of coverage, accessibility, and reproducibility
Elevated suicidal thoughts and behaviors among adults reporting symptoms of Cannabinoid Hyperemesis Syndrome: Results from a national survey of US adults
No full textABSTRACT
Objective: As cannabis use has increased in the United States, so has cannabinoid hyperemesis syndrome (CHS), a disorder characterized by severe nausea, vomiting, and abdominal pain among heavy cannabis users. We previously showed that CHS symptoms are associated with several behavioral and psychological characteristics linked to psychosocial impairment. We examined links between CHS symptoms and suicidal thoughts, behaviors, and proximal suicide risk factors.
Methods: We used data from the National Firearms, Alcohol, Cannabis, and Suicide survey, a nationally representative survey of 7,034 US adults. Items assessed symptoms of CHS and suicidal thoughts and behaviors. Comparisons focused on: those with daily cannabis use and CHS symptoms (n = 191), those with daily cannabis use without CHS symptoms (n = 882), those with past year cannabis use but not daily use (n = 1288), and those without past year cannabis use (n = 4673).
Results: Those with CHS symptoms reported the highest prevalence of suicidal thoughts and behaviors with most lifetime rates being significantly higher than those with daily cannabis use without CHS symptoms. Those with CHS symptoms also reported higher mean-levels of thoughts and feelings associated with suicide (i.e., perceived burdensomeness, thwarted belongingness, defeat, entrapment) than all the other groups.
Conclusions: Those with CHS symptoms reported especially high rates of suicidal thoughts, behaviors, and attempts even when compared to others with daily cannabis use. People with CHS symptoms appear to be at high risk of suicide, possibly related to distress from their gastrointestinal symptoms and psychiatric, substance use, and medical comorbidities
