Advances in technologies including development of smartphone features have contributed to the growth of mobile applications, including dating apps. However, online dating services can be misused. To support law enforcement investigations, a forensic taxonomy that provides a systematic classification of forensic artifacts from Windows Phone 8 (WP8) dating apps is presented in this study. The taxonomy has three categories, namely: Apps Categories, Artifacts Categories, and Data Partition Categories. This taxonomy is built based on the findings from a case study of 28 mobile dating apps, using mobile forensic tools. The dating app taxonomy can be used to inform future studies of dating and related apps, such as those from Android and iOS platforms.  相似文献

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.  相似文献

Power in the world??s preeminent international financial institutions??the World Bank and the International Monetary Fund??resides in their Executive Boards. How do governments get elected to these international committees? This study quantitatively explores whether wealthy governments provide more foreign aid to poor governments that offer them political support. The focus is on Switzerland, which is elected to the Executive Board of the Bretton Woods Institutions by a group of countries from Central and Western Asia, and Eastern and Southern Europe. Results confirm the hypothesis. Implications for governance in a multipolar world are discussed.  相似文献

This article uses data from the 2008 Cooperative Congressional Election Study to explain weak support for public financing of congressional campaigns. Previous studies lack theory to explain variation in support and use a flawed measure of the dependent variable. We argue that low support reflects a failure resulting from a collective action dilemma. Citizens desire a campaign finance system that weans politicians from private donors, but are unwilling to pay a small amount in taxes to support public financing. In contrast to conventional wisdom, we show that support for public financing is highest among those perceived to benefit the most from the current system. Our results suggest that most Americans would rather not pay for politics, and that reform proposals must avoid incurring transparent costs on individual citizens to pay for reform.  相似文献

Commission of nonsexual crimes generally antedates officially recorded sexual offenses. In particular, burglary has been hypothesized to be a potential ‘stepping stone’ in the development of one's sexual criminal career in the same way that marijuana has often been considered a ‘gateway drug’ to more serious drug-related offenses. The present study examined the officially recorded criminal histories of 828 male sex offenders to determine the relevance of burglary in their criminal histories. One third of the men in the sample (n=281, 34%) had been charged at least once for burglary. These 281 men committed a total of 762 separate incidents of burglary. Offenders with at least one officially recorded charge for burglary (BSOs) were compared with those with no such charges (SOs). Next, the characteristics of each burglary were examined and four distinct types of burglary were identified: nonsexual, covertly sexual, overtly sexual, and combination burglary/rape. BSOs accrued twice as many charges as the SOs and were significantly more likely to have an earlier age of onset, a longer criminal career, more employment problems, elementary school problems, antisocial behavior, and substance abuse.  相似文献
