Forensic Analysis of Digital Dynamic Signatures: New Methods for Data Treatment and Feature Evaluation

This study explored digital dynamic signatures containing quantifiable dynamic data. The change in data content and nature necessitates the development of new data treatment approaches. A SignPad Omega digitizing tablet was used to assess measurement reproducibility, as well as within‐writer variation and the occurrence of correctly simulated features. Measurement reproducibility was found to be high except for pressure information. Within‐writer variation was found to be higher between days than on a same day. Occurrence of correct simulation was low for features such as signature size, trajectory length, and total signature time. Feature discrimination factors combining within‐writer variability and the occurrence of correctly simulated features were computed and show that signature size, trajectory length, and signature time are the features that perform the best for discriminating genuine from simulated signatures. A final experiment indicates that dynamic information can be used to create connections between simulation cases.

The experience of pregnancy and childbirth for unmarried mothers in London, 1760-1866

This article explores the experience of pregnancy and childbirth for unmarried mothers in the metropolis in the eighteenth and nineteenth centuries. It draws upon, in particular, the infanticide cases heard at the Old Bailey between 1760 and 1866. Many of the women in these records found themselves alone and afraid as they coped with the pregnancy and birth of their first child. A great deal is revealed about the birthing body: the ambiguity surrounding the identification of and signs of pregnancy, labour and delivery, the place of birth and the degree of privacy, and the nature of, and dangers associated with, solitary childbirth.     

On the Trail of the ‘Lions of Islam’: Foreign Fighters in Afghanistan and Pakistan, 1980-2010

This article provides a review of the history of jihadi foreign fighters in Afghanistan over the last 30 years. It details the post-9/11 period and the invasion of Afghanistan by U.S. forces, focusing on the ethnic origin of the foreign fighters and how different groups engaged in different aspects of the conflict. Additionally, the piece explains that while the foreign fighters who came to fight alongside the Taliban in Afghanistan included, among others, Uzbekistanis (not Afghan Uzbeks), Turks, and Arabs, there was also a significant force of Pakistanis—of both Pashtun and Punjabi origins—that joined, bolstering the Taliban army.     

Case series of completed suicides by burning over a 13-year period

Suicide by burning is an extreme act that is uncommon in the United States and throughout the Western world. The characteristics of people who complete such acts are not well understood. To address this issue, we examined the death records of the King County Medical Examiner's Office in Washington State over the 13 years from 1996 to 2009. Twenty-five cases of suicide by burning were identified and used to characterize decedent demographics, circumstances of death, and motivating factors. Compared to other methods of suicide, burning demonstrated a significant overrepresentation of decedents who were women, 40-59 years of age, and Asian/Pacific Islander. They also tended to have previous psychiatric illness and/or substance abuse issues. Self-burning predominantly occurred at the decedent's residence with the intent of suicide given. There was no unifying theme in motivating factors. Together, these data represent the characteristics of people whose death is because of suicide by burning in King County, Washington.     

Accidental through and through penetrating injury to the neck

We present the case of a 24-year-old driver who died when a metal pole entered the front windshield, traveled through the victim's neck, and then exited via the back windshield. This case illustrated an unusual penetration injury and the importance of a thorough and complete death scene investigation.     

The cartelization of local governments

Intergovernmental competition can enhance efficiency. Centralization of government expenditures inhibits intergovernmental competition because it makes governments more homogeneous, and so cartelizes local governments. Cartelization reduces Tiebout competition, and limits benchmark competition in which one government??s performance can be compared with neighboring governments. Measuring fiscal centralization as the ratio of local to state and local government expenditures within the state, the evidence shows that more fiscal decentralization is associated with higher levels of state per capita income. Cartelization of local governments negatively impacts income.     

P300测谎的新取向

现在,P300是研究者使用的最多也是研究的最深入的一种脑电指标。根据实验模式的不同,目前的P300研究可以分为两大类：模拟犯罪模式和自传性信息模式。而目前P300研究的取向则集中在三个方面：一个是关于反测谎对P300的影响;一个则探讨撒谎动机或意向对P300的影响;还有一些研究则集中在将P300与其他脑电指标结合测谎上。如今,P300测谎的实验室研究已经颇有成效,但仍有生态效度不足的缺点。今后P300测谎研究应该以实际生活中的真实犯罪案件或普通人的过失行为为主,提高实验的生态效度及应用性。     

信息社会警务公关危机及应对策略

信息社会中,公安机关成为媒体关注的焦点,这给警务公安带来了严峻的挑战。面对这种挑战,公安机关出现与媒体关系处理不当,反应迟缓、警察形象受到挑战等被动反应。公安机关应做到,全面认知、客观分析形势;创新设备应对机制;巧妙表达公安工作;高效运作。
