inter-rater reliability

Coding motives reproducibly in mass murder datasets requires a structured, rule-based protocol with predefined categories, multiple coders for inter-rater reliability, and clear decision hierarchies to minimize subjectivity.[pmc.ncbi.nlm.nih] Define Categories Establish exhaustive, mutually exclusive motive classes upfront, such as psychosis (delusions/hallucinations), ideology (political/religious extremism), personal grievance (romantic rejection, grudges), rage (disputes), or despair (life events), mirroring analyses of 1,725 cases from 1900-2019. Prioritize primary motive via hierarchy: clinical evidence trumps manifestos; use subcategories for granularity (e.g., romantic vs. non-romantic grudge).[pmc.ncbi.nlm.nih] Coding Protocol Extract data from sources like manifestos, psych records, witness accounts, and media using standardized templates: note verbatim quotes, timestamps, and context. Assign codes blindly by independent raters (aim for Cohen’s kappa >0.8); resolve discrepancies via adjudication rounds with documented rationale. Automate initial passes with NLP keyword matching (e.g., “Allah” flags ideology), followed by manual verification.[arxiv +1]

Just leaving this here These children display reactive aggression and delusional thinking early on, with physical abuse amplifying risks through disrupted attachment and impulse control. Such profiles enable partial prediction of extreme violence, though ethical intervention dilemmas arise.[pmc.ncbi.nlm.nih +1]

Pittsburgh stands out as America’s steepest walkable city due to its extreme hills and extensive pedestrian infrastructure. The city features Canton Avenue, recognized as the steepest public street in the continental U.S. with a 37% grade.[youtube +2] Key Features Pittsburgh boasts over 800 public staircases totaling about 25,000 feet of elevation change, earning it the nickname “City of Steps.” These stairs make steep terrain navigable on foot, supporting walkability despite dramatic inclines like Dornbush Street at 32%.[islands +1]

The things I saw beggar description. The visual evidence and the verbal testimony of starvation, cruelty and bestiality were so overpowering as to leave me a bit sick." Gen. Dwight D. Eisenhower to Gen. George C. Marshall April 15, 1945 describing visit to a German concentration camp

It works Immediate brain effects Short cold-water immersions trigger a surge in key neurotransmitters involved in attention, mood, and stress regulation.[pmc.ncbi.nlm.nih] • Whole‑body cold immersion increases serotonin, dopamine, norepinephrine, cortisol, and β‑endorphin, which are central to emotion regulation, stress response, and reward processing.[pmc.ncbi.nlm.nih] • After a single cold‑water bath, participants report feeling more active, alert, attentive, proud, and inspired, and less distressed and nervous.[pmc.ncbi.nlm.nih] Cold exposure also changes large‑scale brain network connectivity in ways that may relate to antidepressant effects.[pmc.ncbi.nlm.nih] • fMRI work shows increased coupling between medial prefrontal cortex and anterior insula/dorsolateral prefrontal cortex, and decreased coupling between medial prefrontal cortex and anterior cingulate cortex after cold immersion, patterns linked to better emotion regulation and reduced depressive rumination.[psychiatrypodcast +1] • These connectivity shifts track with increased positive affect rather than just reduced negative affect, suggesting enhanced cognitive flexibility and self‑regulation.[pmc.ncbi.nlm.nih]

This is cute Mercedes, Fernand’s wife and Edmond Dantès’ former fiancée, gets caught in the crossfire as Fernand (played by Guy Pearce) fires wildly at the Count (Edmond, played by Jim Caviezel) in a desperate bid for revenge. She is wounded but survives the gunshot, which occurs amid the chaos of their final showdown at the Count’s estate. This moment underscores Fernand’s unraveling desperation after his betrayals are exposed.[moviemistakes]
