Forensic investigation of OOXML format documents

MS Office documents could be illegally copied by offenders, and forensic investigators still face great difficulty in investigating and tracking the source of these illegal copies. This paper mainly proposes a forensic method based on the unique value of the revision identifier (RI) to determine the source of suspicious electronic documents. This method applies to electronic documents which use Office Open XML (OOXML) format, such as MS Office 2007, Mac Office 2008 and MS Office 2010. According to the uniqueness of the RI extracted from documents, forensic investigators can determine whether the suspicious document and another document are from the same source. Experiments demonstrate that, for a copy of an electronic document, even if all the original characters are deleted or formatted by attackers, forensic examiners can determine that the copy and the original document are from the same source through detecting the RI values. Additionally, the same holds true if attackers just copy some characters from the original document to a newly created document. As long as there is one character left whose original format has not been cleared, forensic examiners can determine that the two documents are from the same source using the same method. This paper also presents methods for OOXML format files to detect the time information and creator information, which can be used to determine who the real copyright holder is when a copyright dispute occurs.     

UNTIL DEATH DO US PART? WHY COURTS SHOULD EXPAND PRENUPTIAL AGREEMENTS TO INCLUDE TEN‐YEAR MARRIAGES

It has become apparent that marriage, while still strongly valued by society and government, has become less appealing to Americans as a whole. The changes taking place in society, whether economic or moral, have resulted in married couples becoming the minority in the United States. This decrease demonstrates that there is a need for reform, and that couples need to be provided with new options that will incentivize them to choose this union over cohabitation. This Note will discuss how expanding prenuptial agreements to allow couples to contract to the length of their marriage may help to accomplish that goal. This expansion will give couples the ability to tailor their relationship to fit their individual expectations and quell the reservations commonly associated with formalized relationships. Furthermore, such an expansion would be consistent with current law regulating premarital agreements and would still allow state governments to remain involved in regulation, making it less drastic of a reform than privatization.     

Daring to Be Heard: Advertorials by Organized Interests on the Op-Ed Page of The New York Times , 1985-1998

Advertorials are a form of outside lobbying that organized interests use to influence policymakers and attentive publics. It is apparent from their popularity that organized interests consider them to be an effective form of political communication. This article analyzes 2,805 organized interest advertorials that appeared on the lower right quadrant of The New York Times op-ed page from 1985 to 1998. Advertorials take two broad forms: (a) image advertorials, which are paid messages by organized interests designed to create a favorable climate of opinion, and (b) advocacy advertorials, which are sponsored messages intended to win support for an interest's viewpoints on controversial issues. Typologies of advertorials (11 categories), organized interests (21 categories), corporate and noncorporate economic interests (29 categories), and policy content (28 categories) are used to document annually and over time who is sponsoring advertorials, what types of advertorials are being used, what interests avail themselves of advertorial campaigns, which issue areas are receiving attention, what images and policy messages are being communicated, which organizations sponsor the most advertorials, and the timing of such political advertising campaigns. We find over time an increasing number of advertorials, an increasing number and diversity of sponsoring interest organizations, an increasing trend toward advocacy advertorials, a continuing but declining sponsorship dominance by corporate interests, a shifting policy issue emphasis that corresponds to events in the political environment, and evidence that organized interests employ a variety of sponsorship strategies.     

Understanding the media/terrorism relationship: An analysis of ideology and the news in time magazine

Conservative terrorism scholars have made the claim that the media have become a propaganda tool for terrorists and sympathetically portray terrorist activities. This article provides quantitative and qualitative data from Time magazine in 1986 suggesting that this view is mistaken. News production is treated as a social process that both informs and obscures, rather than as a neutral process that simply provides ‘objective’ facts. The results of the investigation reveal seven ways in which ideology is manifested in the terrorism news: semantics, language, headlines, social and historical context, treatment of objectives, trivialization, and amplification of violence. The ideological uniformity and lack of diversity apparent in terrorism news suggests that this kind of treatment results in a lack of understanding of the media/terrorism relationship and serves to support conservative views about the nature of terrorism and appropriate responses to it.     

The Impact of the 1994 Federal Assault Weapon Ban on Gun Violence Outcomes: An Assessment of Multiple Outcome Measures and Some Lessons for Policy Evaluation

The Federal Violent Crime Control and Law Enforcement Act of 1994 bans a group of military-style semiautomatic firearms (i.e., assault weapons) and ammunition magazines capable of holding more than 10 rounds. Ban advocates argue that these weapons are particularly dangerous because they facilitate the rapid firing of high numbers of shots. Though the banned guns and magazines were used in only a modest fraction of gun crimes before the law, it was hypothesized that a decrease in their use might reduce gunshot victimizations, particularly those involving multiple wounds and/or victims. In response to a Congressional mandate for an impact assessment of the law, this study utilized national and local data sources and a variety of analytical techniques to examine the ban's short-term impact on gun violence. The ban may have contributed to a reduction in gun homicides, but a statistical power analysis of our model indicated that any likely impact from the ban will be very difficult to detect statistically for several more years. We found no evidence of reductions in multiple-victim gun homicides or multiple-gunshot wound victimizations. The findings should be treated cautiously due to the methodological difficulties of making a short-term assessment of the ban and because the ban's long-term effects could differ from the short-term impacts revealed by this study.

用RT-PCR法区别生前与死后伤

12只SD大鼠随机分为生前伤、死后伤、麻醉伤和正常对照四组，损伤时间为15min，取创缘皮肤为检材；IL－6引物为寡聚核着酸引物（27hP），内对照引物为Tx基因（20hP），用TRIZOLTMTotalRNA提取试剂盒抽据总RNA，AMV逆转录酶使mRNA逆转录成cDNA，PCR扩增得出：在生前伤、麻醉伤以及正常皮肤中均能扩增出IL－6cDNA片段（590hp）和内对照Tx基因片段（188b），在死后伤组只能扩增出Tx基因片段；图像分析凝胶灰度扫描；生前损伤组与麻醉组无显著性差异，而二者与正常皮肤组有统计学差异。藉此，运用RT－PCR法可以准确区别大鼠实验性损伤的生前伤与死后伤。

基于非营利组织在我国经济与社会发展中的功能与面临的挑战,该文采用定性与定量分析相结合的研究方法,对非营利组织专职人员的专业化现状进行大量的问卷调查与个案访谈,将专业水平操作化为基础知能、专业知能和专业精神三个变量进行测量,发现专职人员普遍存在着低学历,专业技能缺乏和专业精神错位,即整体的专业水平较低的问题.采用SPSS分析软件对影响专业水平和专业身份认同程度的各因素进行频数和相关性分析.通过探讨当前非营利组织专职者专业水平较低的原因和专业化发展需要解决的问题,提出建议:一是完善高校非营利组织工作专业人才的培养机制;二是强化非营利组织专职人员的技能培训;三是树立科学的非营利组织工作专业理念;四是提高非营利组织专职人员的待遇.     

The “timeline” method of studying electoral dynamics

To study the evolution of electoral preferences, Erikson and Wlezien (2012) propose assessing the correspondence between pre-election polls and the vote in a set of elections. That is, they treat poll data not as a set of time series but as a series of cross-sections—across elections—for each day of the election cycle. This “timeline” method does not provide complete information, but does reveal general patterns of electoral dynamics, and has been applied to elections in numerous countries. The application of the method involves a number of decisions that have not been explicitly addressed in previous research, however. There are three primary issues: (1) how best to assess the evolution of preferences; (2) how to deal with missing data; and (3) the consequences of sampling error. This paper considers each of these issues and provides answers. In the end, the analyses suggest that simpler approaches are better. It also may be that a more general strategy is possible, in which scholars could explicitly model the variation in poll-vote error across countries, elections, parties and time. We consider that direction for future research in the concluding section.
