The aim of this study was to analyze the differences between the handwritings of schizophrenia patients and healthy subjects in addition to the changes that occurred in schizophrenia patients' handwriting in response to the treatment. The test subjects were 29 schizophrenia patients and 29 healthy individuals with the same age, gender, and dominant hand. The changes in the handwritings were examined according to 14 different parameters. On the day of admittance, the percentage of extra letters was 16.7%, and after 7–10 days of hospitalization, it rose to 33.3%. The percentage of skipped words decreased from 29.2% to 16.7% after 7–10 days of hospitalization, and to 10% after 3 weeks. The letters written by schizophrenia patients are significantly larger in height and width compared to the control group. The schizophrenia patients showed a higher incidence of crossed-out letters, adding extra words, missing punctuation as well as missing words.  相似文献

Two hundred seventy-five United States coins were discovered in the stomach of a mentally disturbed individual at autopsy. Many coins containing copper were corroded by prolonged contact with gastric juice, with subsequent absorption and deposition of copper in the liver and kidneys. The patient died from complications related to the acute toxic phase of chronic copper poisoning. A discussion of the case, foreign-body ingestion, gastric bezoars and the mechanism of copper toxicity is presented. To our knowledge, this is the first death due to copper intoxication following a massive ingestion of coins.  相似文献

The media disproportionately focus on conventional crime while neglecting the impact of corporate misbehavior. The present research examines U.S. newspaper coverage of a deadly fire at a dance hall in Goteborg, Sweden. This particular incident facilitates an examination of how newspapers treat issues involving culpability of conventional offenders (arsonists) and white collar offenders (the owners of the nightclub and the promoters of the dance). It was found that newspapers disproportionately focused on the direct harm associated with the fire, and generally neglected the role played by the organizers/promoters. Suggestions are offered regarding the need for more complete media coverage of crime, particularly white collar crime. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

An examination of self-report scales of 160 men and 76 of their partners or former partners found significant correlations between jealousy and abusiveness (for coupled dyads) or intrusiveness (for separated dyads). Jealousy was related to borderline personality and to MCMI-II measures of Post Traumatic Stress Disorder. Rejection sensitivity leading to pathological acts, such as abusiveness and intrusiveness, is seen as originating in early insecure attachment and exposure to shaming experiences.  相似文献

The primary aim of any DNA Database is to link individuals to unsolved offenses and unsolved offenses to each other via DNA profiling. This aim has been successfully realised during the operation of the New Zealand (NZ) DNA Databank over the past five years. The DNA Intelligence Project (DIP), a collaborative project involving NZ forensic and law enforcement agencies, interrogated the forensic case data held on the NZ DNA databank and collated it into a functional intelligence database. This database has been used to identify significant trends which direct Police and forensic personnel towards the most appropriate use of DNA technology. Intelligence is being provided in areas such as the level of usage of DNA techniques in criminal investigation, the relative success of crime scene samples and the geographical distribution of crimes. The DIP has broadened the dimensions of the information offered through the NZ DNA Databank and has furthered the understanding and investigative capability of both Police and forensic scientists. The outcomes of this research fit soundly with the current policies of 'intelligence led policing', which are being adopted by Police jurisdictions locally and overseas.  相似文献
