A Coordinated Community Response to Intimate Partner Violence on the College Campus

Recent statistics indicate that intimate partner violence is magnified on college campuses. In the university setting, victims of intimate partner violence may encounter numerous agencies (e.g., campus police, local courts, victim advocates) following reporting of victimization. The need for a coordinated community response to intimate partner violence of college students has been emphasized in recent years, yet little research has been conducted. This qualitative, exploratory study examines perceptions of 15 service providers in a recently implemented, campus-based, coordinated community response. Narrative data from semistructured interviews indicate that service providers are generally satisfied with the current response, but report a need for increased training and resources. Implications for future research, education, and public policy are discussed.

Use of lycode powders for the examination of documents partially written with erasable ball point pen inks

It was discovered by change that lycode powders adhere to erasable ball point pen ink strokes. A study of this phenomenon was carried out to determine what type of inks reacts physically with lycode powders. A further evaluation was made to learn if this effect continued after the erasable ink became indelible. It was also found that obliterated erasable ball point pen ink can be read by applying lycode powders and that the powders react in a similar way with typewriting from a conventional inked typewriter ribbon. Treatment in this case is completely non-destructive since the lycode powder can be wiped off the paper surface.     

The marriage license as a hitting license: A comparison of assaults in dating,cohabiting, and married couples

There are many studies of marital and dating violence. However, methodological differences between these studies make it difficult to determine differences in the nature and extent of physical assault between marital status groups. This paper helps fill that gap by analyzing data from two surveys: a study of 526 dating couples at a large midwestern university, and a study of a national probability sample of 5005 married and 237 cohabiting couples. The results show that cohabiting couples have a higher rate of assault than dating and married couples. These findings persist after controls for age, education, and occupational status are introduced. Violence is also more severe in cohabiting than dating or married couples. A number of factors may account for the more frequent violence in cohabiting relationships. These include social isolation, the issue of autonomy and control, and the investment in the relationship.

Initial Results on the Composition of Fingerprints and its Evolution as a Functionof Time by GC/MS Analysis

Abstract: Determining the time since deposition of fingermarks may prove necessary to assess their relevance to criminal investigations. The crucial factor is the initial composition of fingermarks, because it represents the starting point of any aging model. This study mainly aimed to characterize the initial composition of fingerprints, which show a high variability between donors (inter‐variability), but also to investigate the variations among fingerprints from the same donor (intra‐variability). Solutions to reduce this initial variability using squalene and cholesterol as target compounds are proposed and should be further investigated. The influence of substrates was also evaluated, and the initial composition was observed to be larger on porous surface than nonporous surfaces. Preliminary aging of fingerprints over 30 days was finally studied on a porous and a nonporous substrate to evaluate the potential for dating of fingermarks. Squalene was observed to decrease in a faster rate on a nonporous substrate.     

激光显微共聚焦拉曼光谱仪对红色墨迹的研究

目的利用激光显微共聚焦拉曼光谱仪对文书中常见的红色墨迹材料进行表征,研究该方法对红色墨迹材料的区分能力。方法在785nm激发波长,50倍物镜条件下,对49种红色印文,以及9种彩色喷墨打印和13种彩色激光打印的红色墨迹材料进行拉曼光谱表征。结果通过对71种墨迹样品的谱图进行分析,可以发现,红色印文墨迹、喷墨打印红色墨迹及激光打印红色墨迹的拉曼光谱间均存在差异,同时,拉曼光谱可将这三种墨迹材料分别进一步区分。结论显微共聚焦激光拉曼光谱可对红色墨迹材料进行有效表征和区分。这一方法可对红色印文墨迹进行识别,并且可实现对伪造印文文件的鉴别。     

Suspect graveyard burial (South Armagh,N. Ireland): Combined search,forensic anthropology and radiocarbon dating

Geophysical investigation of a former convent graveyard for conversion to a community centre identified an unrecorded, unmarked burial below a later burial. Archaeological excavation confirmed the presence of skeletonized human remains, considered by police as a possible clandestine burial. Mortuary examination indicated the remains belonged to a mature adult female. To determine whether the deceased could be a recorded missing person, radiocarbon dating was undertaken on a femur and a rib bone. This is not always straightforward, and results showed two possible ages due to intercepts on either side of the nuclear weapons testing spike in atmospheric ¹⁴C; however, the later dated burial allowed us to constrain the date of a rib to CE 1959. This study demonstrates that dating a second tissue with a longer turnaround time, such as a femur, can help to constrain which side of the bomb spike is most probable. This paper documents in one work the search, scene and sample and then advances this to resolution by anthropological analysis and radiocarbon dating of human remains.
