The impact of extralegal factors on perceived credibility of child victims of sexual assault

ABSTRACT

The study examined the impact of victim age, victim gender, and perpetrator gender, across five domains of witness credibility: accuracy, believability, competency, reliability and truthfulness. The study also investigated which of these sub-constructs is the best predictor of guilt. 231 adult lay-people completed a survey measuring perceived credibility. Victim age emerged as having the most consistent effect, with the 5- and 10-year-old victims rated as more credible than the 15-year-old victim. Despite their legal incapacity to consent to sex, 15-year-old victims appear to be viewed as ‘quasi-adults’. Victims were rated as more accurate and truthful when the defendant was male compared to when the defendant was female. This may be due to the availability heuristic, as cases involving female defendants are less common. A significant main effect for victim gender was found for the competency sub-construct, such that males were rated as more competent than females. This result suggests that gendered attitudes and stereotypes may begin in childhood and extend to complainants of sexual assault. Main effects for accuracy and truthfulness, were qualified by three-way interaction effects. The five-factor model of perceived credibility accounted for 42% of variance in guilt perceptions, with truthfulness emerging as the strongest predictor of guilt.     

The detection of sedatives in hair and nail samples using tandem LC-MS-MS

Drug screening methods were developed to detect alprazolam, clobazam, clonazepam, diazepam, midazolam, oxazepam, temazepam, triazolam, zopiclone, and selected metabolites in human hair and nail samples employing liquid-liquid extraction and tandem liquid chromatography-mass spectrometry (LC-MS-MS). Hair and nail samples were obtained from patients who had recently discontinued or were currently prescribed one or more of the targeted drugs. Prazepam was used as the internal standard for all compounds. Some components in the hair matrix gave the same transitions as some of the analytes but did not compromise the analyses because their retention times differed from those for the target compounds. The analytical run time was 8-10min. Results of the hair analysis of a DFSA victim are also presented.     

The Darkest Figure of Crime: Perceptions of Reasons for Male Inmates to Not Report Sexual Assault

Although sexual assault behind bars is recognized as problematic, very few of the sexual assaults that occur behind bars are officially reported. Many researchers have examined the individual and institutional variables which can help predict an inmate’s probability of being victimized by his fellow inmates. With a sample obtained from a sample of eight Texas prisons, the current survey will disentangle the individual, institutional, and individual–institutional level variables which contribute to the rationales behind inmates choosing to report or not report sexually assaultive behavior. The findings somewhat mirror the findings of sexual assaults in the free community, with inmates indicating that the primary reasons to not report include embarrassment, fear of harassment, and retaliation from the perpetrator.     

The Rebirth of Water as a Weapon: IS in Syria and Iraq

The so-called Islamic State (IS) has increasingly used water as a weapon in order to further its political and military aims in Syria and Iraq. In this water-scarce region, IS has retained water and cut off crucial supplies, flooded large areas as well as contaminated resources. The capture of large dams in the Euphrates and Tigris basin has made it possible to deploy the water weapon even more effectively and in a frequent, systematic, consistent and flexible manner. Measures to counter this weaponisation effectively have been limited to military means. However, several internal constraints create a dilemma for IS as its state-building ambitions conflict with the consequences of the weaponisation of water. The rebirth of using the water weapon in Syria and Iraq raises questions about protecting water infrastructures in conflict and post-conflict settings.     

走私武器弹药犯罪的侦查与预防对策

走私武器弹药是一类严重的犯罪行为，其犯罪主体、作案渠道、行为手段、社会危害、侦查难点均存在着特殊性，必须予以高度关注。为有效打击走私武器弹药的犯罪行为，需要综合运用控制下交付、技术侦查、网络侦查、侦查协作等多种侦查手段。对此类犯罪的预防，需要从加强海关监管、市场监管、网络监管、深入开展法制教育、完善情报信息交流等方面入手。     

Penetration Depth of Projectiles Fired from a Replica of Colt Navy of 1851 in 20% Gelatin Blocks Correlated with Fatal Injuries Assessed in an Autopsy of a 78‐Year‐Old Man

Pursuant to the Polish Weapons and Ammunitions Law, muzzle‐loading black powder weapons, manufactured before 1885, or their replicas, as well as suitable projectiles, can be possessed legally without registration and special licenses. The aim of the study was to assess the penetration depth of projectiles fired from a black powder weapon, replica of Colt Navy of 1851, in 20% gelatin blocks and to compare the obtained results with the actual injuries found on autopsy of a 78‐year‐old man who had committed suicide. In the experiments, we used the black powder weapon and ammunitions, as well as gelatin blocks serving as a soft tissue model. We ascertained that solid spherical projectiles fired from black powder weapons cause extensive injuries, especially in the initial segment of the wound canal. Additionally, based on the presence and location of the wad in the wound canal, the distance from which the shot was fired can be determined.     

Background Levels of Salivary-α-amylase Plus Foreign DNA in Cases of Oral Intercourse: a Female Perspective

Saliva plus DNA from a suspect is commonly encountered in sexual assault cases on bodily swabs. However, without background knowledge, the weight of this evidence is unknown. It may indicate the presence of saliva resulting from cunnilingus, or it may represent indirect transfer. In this study, females who refrained from cunnilingus donated 43 items of underwear and 19 vaginal swabs. The samples were subjected to Phadebas^®, RSID^™-Saliva and mRNA profiling and were subsequently DNA-profiled to determine the prevalence of background saliva in the female population. The results report that 15.8% of females who refrained from cunnilingus were positive for saliva and a further 10.5% also had DNA from unknown source(s). These findings of the rate of indirect transfer were evaluated with the Bayesian approach, and it was found that the evidence of saliva plus a high foreign DNA source adds moderately strong support to the allegation of cunnilingus.     

Victims of Sexual Violence in the Canadian Criminal Courts

The literature on victims of sexual violence in the criminal justice system has overwhelmingly pointed to the negative impact of these encounters. This research project sought to explore various aspects that might contribute to harm by conducting in-depth qualitative interviews and collecting limited quantitative data on 31 victims who had encountered various processes in the justice system. Results indicated a wide range of experiences, indicating that no interactions within the system were universally harmful or helpful. Victim experience was shaped by the attitudes and behaviors of specific people within the system demonstrating the importance each individual plays in their official capacity. In the final analysis however, victim satisfaction with the jail term was key to understanding experiences of harm.     

Alcohol concentration and the ability to form intent

The ability to form intent to commit a particular act is often a significant issue in criminal litigation. Often, a complicating factor in the resolution of this issue is the presence of ethanol and drugs in the individual whose motives are to be ascertained. To determine whether an intoxicating blood ethanol concentration (BAC) in the absence of other information is sufficient to establish intent, we reviewed cases investigated by the Office of the Chief Medical Examiner, State of Maryland over a two-year period. Specifically, we identified cases of suicide with a suicide note, the presence of ethanol and the absence of other psychoactive drugs. The BACs ranged from 0.01 to 0.37 g/dL. The average BAC was 0.14 g/dL and the median BAC was 0.13 g/dL. Twenty-five of the 37 cases had a BAC greater than 0.08 g/dL. We conclude that a BAC alone is not sufficient to determine the capability of an individual to form intent to commit a particular act.     

The Impact of Relationship Status, Gender, and Minor Status in the Police Response to Domestic Assaults

Data from police records on 320 domestic violence calls for assistance collected during a four-month period from five jurisdictions operating under a pro-arrest statute in a Northeastern state were examined to determine the distribution of incidents by victim-suspect household relationship. It was hypothesized that, despite the lack of any statutory distinction, police compliance with the requirements of a pro-arrest statute—and mandatory arrest policies—would be higher in incidents involving a parent complainant than in incidents between other household members. Logistic and ordinary least-squares regression indicated that the odds of arrest for cases of child to parent and sibling assault were significantly higher than for other kinds of relationships, especially adult partner cases. Analyses also revealed that police compliance with victim assistance actions was significantly less likely for victims of parent to child and sibling violence relative to other victim-suspect relationships. The police were also more legalistic in the application of the statute to both female victims and female suspects. The implications of the increased role of extra-legal variables in the arrest decision (i.e. age, gender and relationship status) and the police support of parental authority are examined.
