As usage of the Internet has grown to approximately 657 million users worldwide, criminality online has become more prevalent. Termed “cybercrime,” this form of criminal behavior can occur in several different. While cybercrime in general is fairly new comparably to crimes in the physical realm, one of the most recently recognized forms of cybercrime is cyberbullying. The present study will examine the victimoffender relationship. Results indicate that both males and females with lower levels of self-control were more likely to participate in cyberbullying by posting hurtful messages or pictures to Facebook. Second, both sexes were more likely to cyerbullying via Facebook if they had been cyberbullied as well. 相似文献

Police witness intelligence stated a murdered adult male “Fred” had been vertically buried in wooded hilly terrain 30 years ago in the Midlands, U.K. Conventional search methods were unsuccessful; therefore, the police requested a geophysical investigation to be undertaken to determine whether “Fred” could be detected. A multiphased geophysical approach was conducted, using bulk ground conductivity and metal detectors, then follow‐up magnetics and ground penetrating radar (GPR) survey profiles on electromagnetic (EM) anomalous areas. A tight grid pattern was used to account for the reduced target size. Relatively high‐resolution EM and GPR techniques were determined optimal for this terrain and sandy soil. Geophysical anomalies were identified and the most promising intrusively investigated, and this was found to be a large boulder and tree roots. Study implications suggest careful multiphase geophysical surveys are best practice and give confidence in cold case searches. This study yielded a no‐body result, effectively saving police time and costs from further investigations. 相似文献

ABSTRACT Police agencies have adopted social media quite widely, but researchers have paid relatively little attention to the phenomenon. To date few studies have explored public reaction to police use of social media. The current study uses a purposive sample with 7,116 police Facebook posts collected from 14 different police agencies during a one-year period to answer two principal research questions: (1) with respect to the number of likes, number of shares, or number of comments regarding different themes present in police Facebook posts, are there differences among police agencies corresponding to differences in the thematic content in their postings? and (2) What factors are related to the public reaction (i.e., likes, shares, comments) to a police Facebook post? The findings from ANOVA and negative binomial regression models clearly indicate that citizens do have definite preferences on police Facebook posts – they are more likely to like and make comments on posts of police personnel and police-public relations, but less likely to share posts of Social Networking Sites. Also, they are more prone to like posts with narratives and pictures, but less likely to favor posts containing hyperlinks. Policy implications and practice guidelines, study limitations, and future research are also discussed. 相似文献

This article challenges traditional accounts of the 1946 Cold War Crisis in Iran by moving beyond Soviet–American confrontation to focus on British policy. In contrast to the United States, Britain was a major stake-holding power in Iran due to the valuable holdings of the Anglo–Iranian Oil Company (AIOC). By comparing the reactions of the AIOC and Foreign Office, continuity between the events of the 1946 Crisis and later developments in the Mosaddegh premiership becomes apparent. Soviet interference in Azerbaijan prompted great concern from representatives in Iran, but the central Foreign Office pursued a more cautious policy. Only concerns relating to the growth of domestic Iranian communism in the form of the Tudeh Party and the threat this entailed to the British concession prompted the Foreign Office and AIOC to take measures rendering them partially complicit in the internationalization of Iranian politics, setting an important precedent for future action. This article evaluates the policy-making process and its impact on Anglo–Iranian relations by utilizing records from the UK National Archives, British Petroleum Archive and diplomatic personal papers. 相似文献

In forensic science, biological material is typically collected from evidence via wet/dry double swabbing with cotton swabs, which is effective but can visibly damage an item's surface. When an item's appearance must be maintained, dry swabbing and tape‐lifting may be employed as collection techniques that are visually nondestructive to substrates' surfaces. This study examined the efficacy of alternative swab matrices and adhesive lifters when collecting blood and fingerprints from glass, painted drywall, 100% cotton, and copy paper. Data were evaluated by determining the percent profile and quality score for each STR profile generated. Hydraflock® swabs, BVDA Gellifters®, and Scenesafe FAST? tape performed as well as or better than cotton swabs when collecting fingerprints from painted drywall and 100% cotton. Collection success was also dependent on the type of biological material sampled and the substrate on which it was deposited. These results demonstrated that alternative swabs and adhesive lifters can be effective for nondestructive DNA collection from various substrates. 相似文献

An Analysis of the Characteristics of Thoracic and Abdominal Injuries Due to Gunshot Homicides in Israel 下载免费PDF全文

De‐identified wound data from 197 homicidal gunshot postmortems were obtained between 2000 and 2008. Forensic ballistics data were only available for cases between 2004 and 2008. Males represent 91% of gunshot victims and were struck in the thorax/abdomen with an average of 2.3 bullets. The type of firearms involved were semi‐automatic pistols in the predominant caliber 9‐mm Luger and assault rifles in caliber 5.56 × 45 mm and caliber 7.62 × 39 mm Soviet, using full metal jacket bullets. The majority of shootings occurred at ranges of 1 m or greater. The most common bullet path was front to back in 66% of cases. Entry wounds occurred more often on the left side of the thorax, abdomen, and back. The most common critical organs/tissues to sustain bullet trauma in descending order were as follows: heart, lungs, liver, aorta, spleen, kidneys, and vena cava. Ribs were struck by most bullets that entered the thorax. 相似文献
