Morphologic patterns of lip prints in a portuguese population: a preliminary analysis

Lip prints are thought to have the ability to distinguish individuals and, hence, have a potential use in human identification purposes. However, questions remain regarding their utility for sex determination. This study aimed to classify lip prints for different individuals in a Portuguese population and to determine whether sex differences exist. Lip prints of 25 females and 25 males were obtained using dark-colored lipstick and cellophane tape. Lip prints were analyzed using a magnifying lens and classified according to the Suzuki and Tsuchihashi classification. A Type II pattern was found to be most common. A comparison of lip-print patterns between males and females showed results with a statistically significant difference: Type III pattern was most common in males, and a Type II pattern in females. This study corroborates the hypothesis that lip prints are able to distinguish individuals and may be useful in sex determination.     

LET'S GO TO THE VIDEOTAPE: WHY THE FORENSIC INTERVIEWS OF CHILDREN IN CHILD PROTECTIVE CASES SHOULD BE VIDEO RECORDED*

Child sexual abuse is often difficult to prove due to a lack of physical evidence. In many instances, the only evidence is a child's statement given during a forensic interview. Forensic interviews are conducted to assess whether the child has been abused, to develop a plan to protect a child's safety pending trial, and to provide further investigative leads. Note taking by the interviewer is currently the primary method for documenting what takes place in a forensic interview. Research shows that this form of documentation is problematic because interviewers tend to omit abuse‐related details in their notes. This Note suggests that federal law should require that forensic interviews of children in child sexual abuse cases be video recorded. State law can provide for a policy of video recording even in the absence of a federal law mandate. Video recording would better preserve the child's statements thereby improving the reliability of the information that is obtained during forensic interviews. The child's demeanor would also be fully captured on video as opposed to getting lost in an interviewer's notes.     

Palatal rugae pattern in a Portuguese population: a preliminary analysis

Palatal rugae have been related with specific racial groups and are said to be useful in sex discrimination. This work aimed to characterize the palatal rugae patterns in a Portuguese population. Fifty plaster casts were examined for first and third rugae shape evaluation; shape, frequency, and association with sex were studied. In females, the most prevalent first rugae were the straight type on the right and the curve type on the left; in males, the straight type was the most prevalent on both sides. The most frequent third rugae type was sinuous on both sides, in both sexes. No significant sexual dimorphism in rugae shape was found (p > 0.05). When comparing these results with those from other investigations, it was clear that a particular rugae pattern could be established for different ethnic groups. However, the small sample size justifies further work in larger samples to validate these findings.     

Drug-facilitated sexual assault using tetrahydrozoline

Drug-facilitated sexual assault (DFSA) has been defined as the use of a chemical agent to facilitate a sexual assault. We report two cases of the use of tetrahydrozoline for DFSA. We believe this is the first report with urinary quantification of tetrahydrozoline levels postassault. Blood and urine were obtained c. 20 h postexposure in two cases of reported DFSA. Tetrahydrozoline was not detected in blood but was identified in urine in both victims. After initial identification in the urine using the 2010 update to the AAFS mass spectrometry database library, tetrahydrozoline was quantified at 114 and 150 ng/mL, respectively, using GC/MS. Two unique clinical features reported in these cases were intermittent periods of consciousness and postexposure vomiting. Use of GC/MS was successful in identifying tetrahydrozoline in the 100 ng/mL range up to 20 h postexposure. For victims with late presentation, urine may be a better sample for evaluation for tetrahydrozoline.     

Understanding Elder Sexual Abuse and the Criminal Justice System's Response: Comparisons to Elder Physical Abuse

A great deal of research has considered the dynamics of sexual assault and the way that sexual assault cases are processed and handled in the criminal justice system. Most of this research has focused on sexual assault cases involving younger victims. Very little criminological research has considered the dynamics of elder sexual abuse. To fill this void, the current study uses a sample of 127 elder sexual abuse cases and 314 elder physical abuse cases to shed some light on the dynamics of elder sexual abuse and the way the justice system processes these cases. Attention is also given to the way that the processing of elder sexual abuse cases can be distinguished from the processing of elder physical abuse cases. Results show that a wide range of elder sexual abuse cases are committed and these cases are processed differently than elder physical abuse cases. Implications are provided.     

Collecting and Analyzing DNA Evidence from Fingernails: A Comparative Study,,

Forensic practitioners and crime laboratories regularly collect and analyze fingernail evidence; however, the best techniques for processing such evidence have not been established. In this study, numerous aspects of fingernail evidence processing—collection of exogenous cells, transportation, purification of DNA, and STR analysis—were analyzed using fingernails harboring applied blood or epithelial cells from scratchings. Autosomal STR mixtures resulted when fingernails were soaked or swabbed, while scrapings rarely generated mixtures but exhibited allelic dropout. Y‐STRs yielded single source profiles, with scrapings again showing dropout. A silica‐based kit extraction recovered significantly more exogenous DNA than did organic extraction, neither of which was affected by nail polish. Swabbing nails in succession resulted in some cross‐contamination from exogenous material, while transporting nails together did not, although there was loss of exogenous cells. Optimized nail processing produced complete Y‐STR profiles of male volunteers from female fingernails following scratchings.     

Sexual Dimorphism in Finger Ridge Breadth Measurements: A Tool for Sex Estimation from Fingerprints

Previous research has demonstrated significant sexual dimorphism in friction ridge skin characteristics. This study uses a novel method for measuring sexual dimorphism in finger ridge breadths to evaluate its utility as a sex estimation method from an unknown fingerprint. Beginning and ending in a valley, the width of ten parallel ridges with no obstructions or minutia was measured in a sample of 250 males and females (N = 500). The results demonstrate statistically significant differences in ridge breadth between males and females (p < 0.001), with classification accuracy for each digit varying from 83.2% to 89.3%. Classification accuracy for the pooled finger samples was 83.9% for the right hand and 86.2% for the left hand, which is applicable for cases where the digit number cannot be determined. Weight, stature, and to a lesser degree body mass index also significantly correlate with ridge breadth and account for the degree of overlap between males and females.     

Accommodating Religious Beliefs: Harm,Clothing or Symbols,and Refusals to Serve Others

Is there a middle path between the existing case law of the European Court of Human Rights, which rarely requires accommodation of a religious individual's beliefs, and a ‘general right to conscientious objection’, which would exempt religious individuals from all anti‐discrimination and other rules interfering with manifestations of their beliefs? The author argues that failure to accommodate is better analysed as prima facie indirect discrimination, to highlight the exclusionary effects of non‐accommodation on religious minorities, and that the presence or absence of direct or indirect harm to others (or cost, disruption or inconvenience to the accommodating party) could guide case‐by‐case assessments of whether the prima facie indirect discrimination is justified. The author then applies a harm analysis to the examples of religious clothing or symbols and religiously motivated refusals to serve others, recently considered by the European Court of Human Rights in Eweida and Others v United Kingdom.     

职场性骚扰与女性劳动者权益的法律保障

近年来,职场性骚扰日益成为一个严重的社会问题,不仅直接损害了女性的身心健康,而且从根本上威胁到了女性劳动者的人权.职场性骚扰是两性不平等的产物,它的存在反过来又强化了这种不平等.我国目前在处理职场性骚扰案件方面还存在诸多不足,应该以明确性骚扰概念为起点,建立完善的性骚扰处理机制,以有效应对职场性骚扰的不良影响,确实保护女性劳动者权益.
