Degradation of human DNA extracted from forensic stains is, in most cases, the result of a natural process due to the exposure of the stain samples to the environment. Experiences with degraded DNA from casework samples show that every sample may exhibit different properties in this respect, and that it is difficult to systematically assess the performance of routinely used typing systems for the analysis of degraded DNA samples. Using a batch of artificially degraded DNA with an average fragment size of approx. 200 bp a collaborative exercise was carried out among 38 forensic laboratories from 17 European countries. The results were assessed according to correct allele detection, peak height and balance as well as the occurrence of artefacts. A number of common problems were identified based on these results such as strong peak imbalance in heterozygous genotypes for the larger short tandem repeat (STR) fragments after increased PCR cycle numbers, artefact signals and allelic drop-out. Based on the observations, strategies are discussed to overcome these problems. The strategies include careful balancing of the amount of template DNA and the PCR cycle numbers, the reaction volume and the amount of Taq polymerase. Furthermore, a careful evaluation of the results of the fragment analysis and of automated allele calling is necessary to identify the correct alleles and avoid artefacts.  相似文献

The co-occurrence of domestic violence and child abuse is well documented (Appel, A. E., & Holden, G. W. (1998). J. Fam. Psychol. 12: 578–599; Edleson, J. L. (1999). Violence Against Women 5: 134–154). However, little is known about the correlates of co-occurring wife and child abuse. Analyzing data from the 1985 National Family Violence Survey (subsample N = 2733), this study identified risk factors associated with the co-occurrence of wife and child abuse. One-way ANOVA and chi-square analyses were conducted to compare characteristics of parents, children, and households among subgroups of families reporting some form of abuse. Key differences emerged between the three types of homes compared (i.e., those with child abuse alone, wife abuse alone, or wife and child abuse), indicating possibly distinct etiologies and processes. In particular, the co-occurrence of wife and child abuse was marked by less education, worse health, increased reports of depression, and increased husband drug use. Findings may be useful to practitioners and researchers interested in risk factors for different forms of family violence.The total does not equal 100% because certain states report more than one form of maltreatment per child.  相似文献

In keeping with many countries the UK has moved the problem of sexual offending up the political agenda. On the criminal justice side sentences have been increased and supervision periods extended. On the civil side a raft of new measures have been put in place to regulate the behaviour of sex offenders in the interest of community safety and child protection; this paper examines these measures and, in particular takes the sex offender ‘register’ as a case study to show how political imperatives have been brought to bear with little reference to the research or professional views of practitioners in this area. It is contended that under these political pressures, what starts life as a preventive, regulatory measure can easily become a more punitive measure in its own right; as such it may be liable to challenge by those subject to it for failing to fulfil its primary purpose and for straying across a line between the civil and criminal aspects of intervention.  相似文献

Spamming is a major threat to the formation of public trust in the Internet and discourages broader civil participation in the emerging information society. To the individual, spams are usually little more than a nuisance, but collectively they expose Internet users to a panoply of new risks while threatening the communications and commercial infrastructure. Spamming also raises important questions of criminological interest. On the one hand it is an example of a pure cybercrime – a harmful behaviour mediated by the Internet that is the subject of criminal law, while on the other hand, it is a behaviour that has in practice been most effectively contained technologically by the manipulation of ‘code’ – but at what cost? Because there is not an agreed meaning as to what constitutes ‘online order’ that renders it simply and uncritically reducible to a set of formulae and algorithms that can be subsequently imposed (surreptitiously) by technological processes. The imposition of order online, as it is offline, needs to be subject to critical discussion and also checks and balances that have their origins in the authority of law. This article deconstructs and analyses spamming behaviour, before exploring the boundaries between law and code (technology) as governance in order to inform and stimulate the debate over the embedding of cybercrime prevention policy within the code itself.  相似文献

A curious ownership structure is found in Northern Europe—foundations that own and operate business companies. The foundations are non-profit entities, they have no members and no owners, and they cannot be dissolved. In many cases, these entities control more than 50% of the votes in successful international companies. Obviously, this structure completely blocks the market for corporate control, but it also violates other basic principles of agency theory and corporate finance. Nevertheless, we present evidence that a sample of foundation-owned companies listed on the Copenhagen Stock Exchange are at least as efficient as other listed companies in terms of risk adjusted stock returns, accounting returns and Tobins Q. Thus, they question whether profit-seeking ownership is a necessary condition for competitive enterprise.JEL Classification: D23, G34, L31  相似文献

The author explores materialities as pre-established and co-producing features of criminal proceedings. This is done by discussing courtrooms, files and stories in relation to English Crown Court hearings. The three materialities gain significance in the course of the court hearing, but do not derive from it. They exceed the course of talk-in-court. Once the hearing started, the pre-established materialities can be referred to but not simply modified. Materialities, in this line, provide stability and guidance for the hearing. They facilitate, purify and condense it. However, their temporal separation causes problems for those who run the show. Materialities can be employed but not fully integrated. Unwelcome parts do, at times, disturb, disrupt and complicate the current dealings.  相似文献

The criminal justice system is supposed to protect and serve all members of the community equally; therefore, any prejudicial attitudes harbored by criminal justice students may negatively impact their job performance as future justice professionals. Four hundred and eighty-four students at a large Midwestern university were surveyed on their views toward gay and lesbian persons and issues. The responses of criminal justice majors were compared to the responses of students majoring in other fields. Criminal justice majors tended to have more negative views of gays and lesbians than students in other majors. However, there was not a significant difference between the two groups of students in their willingness to extend rights to and socialize with gay and lesbian individuals.  相似文献

This study examines the importance of victims’ expectations of the police, the decision to arrest, and voluntary contact on satisfaction ratings of the police in domestic violence cases. Based on results from past research and modern police policy, several hypotheses are tested including: fulfilled expectations, offender arrests, and voluntary contacts resulting in positive satisfaction ratings of the police. To investigate these predictions further, the present study utilizes data from a national study on violence against women in the United States. Logistic regression analyses indicate that fulfilled expectations and the arrest decision are important to positive satisfaction ratings. Findings also indicate that involuntary, not voluntary, contact with the police leads to higher satisfaction ratings.  相似文献
