Relative Width and Height of Handwritten Letter

This is an exploratory study that analyzes the width and the height of letters in two texts written by each of the 21 writers analyzed. After detrending the linear, text, and allograph trends, we proceeded to comparing the sizes obtained in different texts. The different detrended series were compared by means of correlation and t‐test. According to the results regarding the width of letters, the texts of 19 of 21 writers correlated strongly, whereas the texts of two writers did not correlate with the limits of the threshold. With regard to the height of letters, texts written by between 18 and 21 writers of 21 writers correlated strongly, whereas texts that did not correlate were within the threshold value. Regarding both the width and the height of letters, of 21 writers, texts written by between 19 and 21 individuals were found to correlate strongly.

论文字检验中非本质性差异点

在文字鉴定工作中，非本质性差异点不同程度地存在着。这种差异点形成的原因是多方面的，其中包括：客观书写条件影响；故意伪装；书写习惯在自身的发展演变等，在文字鉴定中正确认识这些差异点并认真分析其产生的原因，才能作出正确的结论。     

谈鉴定工作中笔迹特征的全面运用

当前,笔迹鉴定工作出现了字数少、案情复杂,案件数量多、摹仿伪造篡改居多、检验难度增大等特点。在笔迹鉴定工作中分析运用笔迹特征时应充分把握摹仿笔迹的特点,详细了解嫌疑人和笔迹样本的情况,全面运用笔迹特征,防止以偏概全,以提高鉴定质量。     

对微弱痕迹计算机优化处理的讨论

物证检验中的痕迹物证图像 ,由于成像系统、记录介质和传输设备的不完善 ,常会造成图像劣质化 ,微弱痕迹图像是劣质化图像的一种。应用计算机图像处理技术 ,通过像素或色级的调整 ,能有效地增强微弱痕迹的反差 ,在物证检验中 ,具有一定的实用价值     

论自我摹写笔迹及其鉴定

自我摹写近20年出现于我国,不同于一般的摹写,属伪装笔迹而非伪造笔迹,不符合摹写笔迹的一般规律,形式比较特殊,其笔迹是摹写笔迹中最难识别的。但通过仔细研究、总结经验,掌握其特点、内在规律及鉴定方法,对此也并非毫无办法。     

Prevalence and Processing of Child Sexual Abuse: A Multi-Data-Set Analysis of Urban and Rural Counties

This study investigated how contextual factors affect the processing of child sexual abuse cases, from reporting to sentencing. We analyzed three types of data: (a) data compiled by the Pennsylvania Coalition Against Rape from monthly reports by all rape crisis centers in the state; (b) data from the Pennsylvania Office of Children, Youth, and Families; and (c) sentencing data from the Pennsylvania Commission on Sentencing. Results indicated that aggregate rates of reporting, substantiation, and sentencing were affected by county levels of expenditure. In addition, reporting and substantiation were affected by county-level factors, such that rural counties, counties with a higher percentage of individuals living below the poverty level, counties with higher expenditures, and counties with a higher percentage of stranger assaults had higher rates of child sexual abuse reporting.

Memory for Positive and Negative Political TV Ads: The Role of Partisanship and Gamma Power

Despite generating widespread contempt, political TV ads play an important informational role in the lives of citizens. This study examines effects of Ad Type (Positive, Negative, and Comparison) on recognition memory for candidate issue positions. Potential moderators (Ad Sponsor Partisanship X Viewer Partisanship, Ad Type X Viewer Ideology, Ad Type X Viewer Partisanship) of political ad memory are explored, and electroencephalography (EEG) recordings are used to examine whether semantic processing (indexed as brain activity in the gamma band frequency range) mediates main or moderated effects of Ad Type on Memory. Results reveal a significant interaction between Ad Type and Partisanship, with Republicans remembering more from positive relative to negative ads (significant), and Democrats remembering more from negative ads (marginally significant). A direct effect of Gamma on Memory highlights the considerable potential that EEG (in general) and the gamma frequency band (in particular) may hold for the study of message processing.     

“Victim Refuses to Cooperate”: A Focal Concerns Analysis of Victim Cooperation in Sexual Assault Cases

Research suggests that victim cooperation is a strong predictor of arrest and prosecution in sexual assault cases. Relatively little research has focused on identifying the factors that shape the decision to cooperate and the research that does exist is largely atheoretical. We address these gaps by examining victim cooperation using a revised version of the focal concerns perspective. We use data on cases reported to law enforcement agencies in Los Angeles to estimate models using factors situated within three victim focal concerns—crime seriousness, costs of cooperation, and likelihood of conviction—for three stages of the case process. We supplement these results with qualitative data from police reports regarding the reasons why victims refused to cooperate. The findings of this study provide initial support for the theoretical development of victim cooperation using the focal concerns perspective and provide potential guidance to criminal justice practitioners on how to increase victim cooperation.
