However, fires in these wooden houses, which have a high fire load, pose a significant public health issue, leading to substantial loss of life and property. This study aimed to evaluate deaths caused by wooden house fires over a 10-year-period from a forensic medicine perspective, with the goal of raising social awareness and providing recommendations for prevention and protection. 87.1% of the victims died at the scene. 68.2% of the bodies exhibited fourth-degree (carbonized) burns. 78.8% showed macroscopic soot contamination in the lower respiratory tract. 69.4% had elevated blood carboxyhemoglobin levels, with a mean value of 41.2%. Identification was achieved through DNA comparison analysis in 36.5% of cases. The study determined that 83.6% of the deaths resulted from direct carbon monoxide intoxication, direct burns, or a combination of burns and carbon monoxide intoxication. To accurately determine both the identity of the deceased and the true cause of death in fire victims, a comprehensive investigation is essential. This includes detailed crime scene examination and extended toxicological, pathological, radiological, and molecular genetic analyses alongside autopsy procedures. Strong correlations were identified between blood carboxyhemoglobin levels, soot contamination in the lower respiratory tract (macroscopic and microscopic), and fire-related causes of death. Furthermore, DNA comparison analysis enables 100% accurate identification, even in highly carbonized bodies.</p>","PeriodicalId":18484,"journal":{"name":"Medicine, Science and the Law","volume":" ","pages":"258024261435764"},"PeriodicalIF":1.7,"publicationDate":"2026-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147513324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main objective of the present research was to customize a deep learning-based convolutional neural network (CNN) model trained on a primary dataset for signature authentication. The model was trained, validated, and tested on the dataset of the 1400 signature images (700 genuine and 700 forged) primarily obtained from the study participants. The signature samples were equally divided into a train (1000 samples comprising 500 forged and 500 genuine signatures) and a test dataset (400 samples comprising 200 forged and 200 genuine signatures) as per the requirements of the model's training and testing procedure. The model's architecture was optimized with different hyperparameters to achieve a higher accuracy rate. The results show that the proposed model attains the training, validation and testing accuracy of 97.32%, 97.92%, and 84.5% respectively. Furthermore, other evaluation matrices were also computed, including precision, recall (sensitivity), F1-score, and specificity with the values of 85%, 84%, 84%, and 90%, respectively. The accuracy matrices provide better performance over the other existing methods. This customized CNN architecture can be trained on larger datasets and directly deployed in the field of forensic science for signature examination.

The primary objective of this study is to conduct a comparative analysis between compensation claims initially advanced by patients (or their legal representatives) in the pre-trial phase and the final outcomes of legal proceedings brought before the court. This article provides an important opportunity for a critical and in-depth analysis of litigation in the fields of cardiology and cardiac surgery, with the aim of improving the efficiency of case management.In the period 2013-2023, San Martino Polyclinic Hospital received a total of 1704 compensation claims, of which 39 (2.29%) were related to alleged cardiological and cardiosurgical professional liabilities. About 64.10% of the compensation claims (25 out of 39) were deemed illegitimate due to the absence of professional responsibility, and were therefore rejected by the Claims Management Committee (CMC). In 38.5% of cases, legal action was pursued, and in four cases, the hospital was ordered to compensate the patient for medical negligence. Conversely, in three cases, the Judge's ruling was in favour of the Hospital. Currently, eight legal actions remain ongoing, and their outcomes are pending.Overall, over the 11-year study period, litigation cases in the cardiology and cardiac surgery fields were relatively infrequent.</p>","PeriodicalId":18484,"journal":{"name":"Medicine, Science and the Law","volume":" ","pages":"258024261419614"},"PeriodicalIF":1.7,"publicationDate":"2026-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146119540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The adapted tool was piloted at a secure forensic unit in England; this consisted of a two-phase approach to data collection comparing the results from an initial assessment (time 1, n = 50), with those of a follow-up assessment conducted three years later (time 2, n = 100). The aim was to assess the practicability of using the tool to measure perceptions of cultural competence among 150 staff members, as part of a wider quality assurance and improvement process. The results indicate that the tool has utility in measuring perceptions of cultural competence and that the information gathered can be used to plan service improvements.

Nevertheless, when and how mental disorder affects moral responsibility is unclear. The insanity defence exculpates a defendant and effectively extinguishes their moral responsibility, although the criteria for insanity varies between different jurisdictions. Most successful cases of insanity are due to delusions, although the nature of delusions itself varies considerably. The recent case of <i>Keal</i> in England and Wales demonstrates some of the problems with the insanity defence, and a coherent philosophical basis for the defence is lacking. I argue that a volitional element should be added to the insanity defence in England and Wales such that a person may be exculpated on the basis of a mental disorder which sufficiently causes any of (1) defects of reason; (2) deficits in knowledge; (3) a lack of control; and (4) their ability to form intentions in crimes of intent, although the threshold should remain high. Reasons-responsive accounts of moral responsibility underpin many of these abilities. The extent to which mental disorder, particularly delusions, are considered a type of manipulation, rather than part of the self, is likely to be contributing to intuitions about exculpation although not all delusions will cause impairments or manipulation to the same extent. Amending the insanity defence in this way would be more just, more philosophically coherent and allow a more consistent approach for those with mental disorders who are charged with criminal offences.</p>","PeriodicalId":18484,"journal":{"name":"Medicine, Science and the Law","volume":" ","pages":"25-34"},"PeriodicalIF":1.7,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143780460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
