This study examined effects of type of and cumulative burden of childhood adversities on bullying and cruelty to animals in the United States. Data were derived from Waves I and II of the National Epidemiologic Survey on Alcohol and Related Conditions, a nationally representative sample of U.S. adults. Structured psychiatric interviews were completed by trained lay interviewers between 2001-2002 and 2003-2004. Although the effects of childhood adversity diminished with the inclusion of confounding variables, several adversities remained significant. For bullying, these included being made to do chores that were too difficult or dangerous, threatening to hit or throw something, pushing, shoving, slapping, or hitting, and hitting that left bruises, marks, or injuries. With respect to cruelty to animals, swearing and saying hurtful things, having a parent or other adult living within the home that went to jail or prison, and adult/other person fondling/touching in a sexual way were significant. The final models indicated that the cumulative burden of childhood adversities had strong effects on the increased likelihood of bullying behavior but not cruelty to animals. 相似文献

In the last few years, a lot of attention has been paid to what is usually called ‘ICT Crime’. In this contribution, the term ICT Crime is analysed from both a practical and theoretical legal perspective. It will be argued that it is very difficult if not impossible to define ICT Crime unequivocally. Furthermore, there seems to be insufficient grounds to see ICT criminality as an autonomous legal discipline, as an independent functional discipline or as a specialisation. An important reason for dealing with ICT Crime as if it is a problem area seems to be fear in governmental organisations that new technology could lead to forms of criminality that are outside their reach of control. Furthermore, the application of ICT has led to a reorientation of legal powers with respect to investigation and prosecution. However, these subjects should be dealt with at an international level. 相似文献

A number of dyed polyamide, wool and silk samples were examined with plane polarized light on their dichroic behavior by optical light microscopy (OLM) and microspectrophotometry with plane polarized light (MSP-PPL). It was found that most of these acid dyed peptidic fibres possess dichroism, but these are weaker than the effects previously described for polyester fibres. The small effects may be not observed, especially for wool, but these can be measured using MSP-PPL.In the three peptidic fibre classes, for the first time, a so called “inverse dichroism” is observed which appears in the absorption spectra as a hyperchromic effect. 相似文献

Age estimation in forensics is essential in cases involving both living and dead subjects. For living subjects, age estimation may be used to establish an individual's status as a minor in cases involving adoption, criminal responsibility, child pornography, and those seeking asylum. Criteria for age estimation in the living have recently been put forth by The Study Group on Forensic Age Diagnostics. The group has proposed guidelines with a three-step procedure: a physical examination and anthropometrical analysis; dental analysis by orthopantomogram (OPG); and X-ray study of the left hand and wrist. The board of FASE highlighted advantages and limits of each method, and suggested practical solutions concerning the age estimation process for adults and subadults. The aim of this study was to verify the applicability of the Greulich and Pyle, and Demirjian techniques on a sample group of Italians, whose ages were known, in determining the skeletal and dental age, in addition to evaluating the reliability of these techniques. 535 subjects between the ages of 7 and 15years were examined, each one undergoing both an orthopantomography (OPG) and radiography of the left wrist and hand. The data obtained underwent statistical analysis. The analyses have shown that a correlation exists between skeletal and dental age, and real age. Age estimation carried out using the Greulich and Pyle method has shown itself to be especially accurate on the Italian sample, particularly in the age ranges of 7-9years and 10.4-11.5years. The Greulich and Pyle method has shown itself to be reliable for the sample analyzed notwithstanding the ethnic differences between the original sample of reference and those analyzed in this study. Application of the Demirjian technique resulted in an overestimation of dental age. This difference is shown to be more highly significant in the higher age ranges. The combination of the Greulich and Pyle, and Demirjian methods have revealed a difference regarding real age, which turns out to be more modest in the younger age ranges and more significant in older subjects. 相似文献

Inkjet ink analysis is the best way to discriminate between printed documents, or even though more difficult, to connect an inkjet printed document with a brand or model of printers. Raman spectroscopy and laser desorption mass spectrometry (LDMS) have been demonstrated as powerful tools for dyes and pigments analysis, which are ink components. The aim of this work is to evaluate the aforementioned techniques for inkjet inks analysis in terms of discriminating power, information quality, and nondestructive capability. So, we investigated 10 different inkjet ink cartridges (primary colors and black), 7 from the HP manufacturer and one each from Epson, Canon and Lexmark. This paper demonstrates the capabilities of three methods: Raman spectroscopy, LDMS and MALDI-MS. Raman spectroscopy, as it is preferable to try the nondestructive approach first, is successfully adapted to the analysis of color printed documents in most cases. For analysis of color inkjet inks by LDMS, we show that a MALDI matrix (9-aminoacridine, 9AA) is needed to desorb and to ionize dyes from most inkjet inks (except Epson inks). Therefore, a method was developed to apply the 9AA MALDI matrix directly onto the piece of paper while avoiding analyte spreading. The obtained mass spectra are very discriminating and lead to information about ink additives and paper compositions. Discrimination of black inkjet printed documents is more difficult because of the common use of carbon black as the principal pigment. We show for the first time the possibility to discriminate between two black-printed documents coming from different, as well as from the same, manufacturers. Mass spectra recorded from black inks in positive ion mode LDMS detect polyethylene glycol polymers which have characteristic mass distributions and end groups. Moreover, software has been developed for rapid and objective comparison of the low mass range of these positive mode LDMS spectra which have characteristic unknown peaks. 相似文献

This paper argues that policies, interventions and discourses pertaining to child prostitution have been guided by overarching political agendas that have masked the underlying structural basis of this phenomenon. These political agendas have shifted in accordance with the locus of power, control and resistance in South Africa since the nineteenth century. On the basis of a historical analysis this paper identifies distinct periods in which child prostitution was used to legitimate policies in favour of social control rather than social development. In the colonial period, child prostitution was used to justify stricter controls on adolescent and adult women's sexuality and movement by colonial and traditional patriarchal authorities. In the colonial and Apartheid periods, policies on child prostitution were informed by fears of miscegenation and sexually transmitted diseases, which were used to support the racist and oppressive legislation of sexual behaviour. In the 1980s and early 1990s, the issue of child prostitution was ‘discovered’ in the press both to deflect attention from the incarceration of juveniles during the 1987 State of Emergency and as the basis upon which liberals attacked the Apartheid state. In the latter half of the 1990s and 2000s, it was used by the African National Congress (ANC) government to attack the moral legacy left by the Apartheid state and in turn deflect responsibility for the root causes of this phenomenon. Furthermore, child prostitution was used to support stricter controls on adult sex workers and on the movement of undocumented migrants. This politicised and sensationalist approach has undermined detailed analysis of the root causes of this phenomenon and children's motivation for engaging in prostitution. For many children in South Africa it has been one means by which they can exercise their agency and power in order to ensure their survival in the face of high levels of socio-economic deprivation and rapid socio-cultural change. This paper therefore proposes a shift from policies and interventions centred on social control to social development, based on an in-depth understanding of children's agency, risk and resilience. 相似文献

This article presents data on the development of a child maltreatment actuarial risk inventory, The Cleveland Child Abuse
Potential Scale (C-CAPS). The study consisted of three groups in a juvenile court setting: child custody cases without indication
of maltreatment (N = 34), cases where maltreatment was indicated (N = 37), and a third middle ground group of cases referred to the court’s Diagnostic Clinic (N = 47). This third group of cases had not elevated to court involvement with a filing of child maltreatment. Study results
provide compelling support for overall classification accuracy, with 100% specificity and 95% sensitivity and an overall hit
rate of 98%, when only the maltreatment and non-maltreatment groups were compared. Adding the third group of possible maltreatment
cases dropped the overall hit rate to 71%. The instrument was able to correctly classify 85% of Non-Maltreatment cases and
76% of Maltreatment cases. The overall factor structure of the instrument is also reviewed. 相似文献
