Nitrate and Nitrite Determination in Gunshot Residue Samples by Capillary Electrophoresis in Acidic Run Buffer, 下载免费PDF全文
Özge Ö. Erol B.Sc. Behice Y. Erdoğan Ph.D. Atiye N. Onar Ph.D. 《Journal of forensic sciences》2017,62(2):423-427
Simultaneous determination of nitrate and nitrite in gunshot residue has been conducted by capillary electrophoresis using an acidic run buffer (pH 3.5). In previously developed capillary electrophoretic methods, alkaline pH separation buffers were used where nitrite and nitrate possess similar electrophoretic mobility. In this study, the electroosmotic flow has been reversed by using low pH running buffer without any additives. As a result of reversing the electroosmotic flow, very fast analysis has been actualized, well‐defined and separated ion peaks emerge in less than 4 min. Besides, the limit of detection was improved by employing large volume sample stacking. Limit of detection values were 6.7 and 4.3 μM for nitrate and nitrite, respectively. In traditional procedure, mechanical agitation is employed for extraction, while in this work the extraction efficiency of ultrasound mixing for 30 min was found sufficient. The proposed method was successfully applied to authentic gunshot residue samples. 相似文献

Trichobezoar in Vagina: Assessment for Child Sexual Abuse and Diagnostic Result of Forensic Science 下载免费PDF全文
Özlem Bağ M.D. Buğra Han Acar M.D. Şenol Öztürk M.D. Sevay Alşen M.D. Çiğdem Ecevit M.D. 《Journal of forensic sciences》2017,62(2):525-527
Vaginal discharge and bleeding in children require a through and thoughtful evaluation to diagnose the underlying problem including infections, sexual abuse, and vaginal foreign bodies. We report a 6‐year‐old girl presenting with bloody vaginal discharge, carefully evaluated for sexual abuse, and finally diagnosed as a vaginal foreign body after vaginoscopy. A rolling hair ball was extracted from the vagina and was diagnosed as trichobezoar pathologically without any endo–ecto‐mesodermal residual tissue. The hair ball was genetically detected and diagnosed to belong herself by containing no foreign structure. Child sexual abuse was ruled out by forensic interview at CAC and report of forensic science that reported genetic structure belonging to the child. Medicolegal assessment helped in final diagnosis to exclude child sexual abuse. 相似文献

Gül Berna Özcan 《Central Asian Survey》2015,34(4):409-417
This special issue illuminates diverse realities of post-Soviet development in Central Asia through a multidisciplinary prism. The contributing articles are grounded in a range of social science disciplines including architecture, anthropology and geography, as well as drawing from mainstream social sciences. The analyses demonstrate how a synthesis of specialist knowledge from area studies and individual disciplinary methodologies can provide well-grounded critical positions on development. 相似文献

Focusing on the Gezi protests, this study addresses two questions: How did a particular struggle against the demolition of a park spontaneously turn into nationwide mass protests? And why was this mobilisation unable to transform itself into a popular counter-hegemonic movement? Drawing on the Laclauian concept of populism, I demonstrate that Gezi mobilised various groups by turning into a symbol of the repressive responses of the hegemonic power to various social demands. This popular mobilisation could not go beyond a conjunctural experience due to its inability to unify heterogeneous protesters and to respond effectively to the counter-strategies of the hegemonic power. 相似文献

Özlem Gürses 《The Modern law review》2015,78(6):1004-1027
The Insurance Act 2015 is the first piece of legislation since the eighteenth century to seek to lay down new principles governing the formation and operation of insurance contracts. Exactly 250 years after Lord Mansfield articulated the routinely‐cited principle of utmost good faith in insurance law in Carter v Boehm (1766) 2 Burr 1905, that principle has been recast, with important implications for both the pre‐ and post‐contractual duties of the parties. The Insurance Act has also imposed important restrictions on the enforcement of policy terms by insurers, and clarifies the law affecting fraudulent claims. The Marine Insurance Act 1906, a codifying measure, looks increasingly outmoded. 相似文献

Using data from a study on police officers’ encounters with domestic violence victims and a study on children experiencing domestic violence, this article examines how officers decide whether and how to communicate with children in emergency situations, and how children experience these encounters. Officers’ views on such communication diverge; usually, communication is motivated by the need to determine next actions. Children recall little communication and describe officers as faceless, nameless and genderless. The authors argue for recognizing the preventive role of officers on emergency calls. Official policies and guidelines should formally acknowledge and clarify the importance of communication with children. 相似文献

MARKETIZED MENTALITY,COMPETITIVE/EGOISTIC SCHOOL CULTURE,AND DELINQUENT ATTITUDES AND BEHAVIOR: AN APPLICATION OF INSTITUTIONAL ANOMIE THEORY* 下载免费PDF全文
We analyze the individual‐level and school‐level determinants of delinquency through the lens of a macro‐sociological theory of crime—institutional anomie theory (IAT). The concept of a “marketized mentality” is introduced as a predictor of students’ delinquency, along with an egoistic/competitive school culture—a feature of the school community. Five hypotheses pertaining to the readiness to use violence and self‐reported delinquency were assessed using multilevel modeling with data from a survey in Germany for 4,150 students clustered in 69 schools. The results largely meet theoretical expectations. The measure of marketized mentality exhibits robust relationships with both forms of delinquency at the individual level, and an egoistic/competitive school culture helps explain variation in levels of these forms of delinquency across schools. Also consistent with expectations, the anti‐social effects of marketized mentality are accentuated for both the readiness to use violence and committing instrumentally motivated property offenses as a competitive/egoistic school climate increases. The results of our analyses reveal that bringing in concepts of IAT can appreciably enhance understanding of the characteristics of students and features of communal school organization that are conducive to youthful offending. 相似文献

Being bullied at school is strongly related to psychological health complaints at the same time point. Studies have also found long-term associations, but few have combined a prospective design with children’s own reports on bullying, and conducted gender-specific analyses. The present study assesses health consequences in young adulthood of self-reported victimization in adolescence using data from Child-LNU in 2000 and the follow-up in 2010 (including 63% of the original sample, n = 813). At ages 10–18 a clear cross-sectional association was found for both girls and boys. Among girls, exposure to bullying also predicted psychological complaints 10 years later, at ages 20–28 (OR = 2.86). This association was not explained by socioeconomic circumstances, neither in adolescence nor in young adulthood. Instead, it can partly be understood as victimization, among adolescent girls, being associated with negative self-image and psychological health as well as with deficits in social resources more generally. 相似文献
