Offending specialization continues to be a subject of empirical inquiry for scholars interested in criminal careers. Early
research consistently spoke to the generality of offending profiles, but more recent work has revealed somewhat mixed findings.
These results have emerged alongside newly developed and applied methods that detect and describe offending specialization.
To what extent these methods shape divergent conclusions and/or provide overlapping insight remains unclear, however. Therefore,
the degree to which more recent inquiries are actually studying the same operational definition of specialization is unknown.
In order to consider this issue further, this study utilizes four frequently applied approaches with a single data set. The
study indicates when and where findings converge and also describes any unique insights provided by each method. The work
concludes with a discussion surrounding the utility of applying multiple strategies in assessing specialization in criminal
offending. 相似文献

The application of isotopic techniques to investigations requiring the provision of evidence to a Court is limited. The objective of this research was to investigate the application of light stable isotopes and isotope ratio mass spectrometry (IRMS) to solve complex forensic cases by providing a level of discrimination not achievable utilising traditional forensic techniques.Due to the current threat of organic peroxide explosives, such as triacetone triperoxide (TATP), research was undertaken to determine the potential of IRMS to differentiate samples of TATP that had been manufactured utilising different starting materials and/or manufacturing processes. In addition, due to the prevalence of pentaerythritoltetranitrate (PETN) in detonators, detonating cord, and boosters, the potential of the IRMS technique to differentiate PETN samples from different sources was also investigated.Carbon isotope values were measured in fourteen TATP samples, with three definite groups appearing in the initial sample set based on the carbon data alone. Four additional TATP samples (in a second set of samples) were distinguishable utilising the carbon and hydrogen isotopic compositions individually, and also in combination with the oxygen isotope values. The 3D plot of the carbon, oxygen and hydrogen data demonstrated the clear discrimination of the four samples of TATP. The carbon and nitrogen isotope values measured from fifteen PETN samples, allowed samples from different sources to be readily discriminated.This paper demonstrates the successful application of IRMS to the analysis of explosives of forensic interest to assist in discriminating samples from different sources. This research represents a preliminary evaluation of the IRMS technique for the measurement of stable isotope values in TATP and PETN samples, and supports the dedication of resources for a full evaluation of this application in order to achieve Court reportable IRMS results. 相似文献

An evaluation was undertaken to determine if isotope ratio mass spectrometry (IRMS) could assist in the investigation of complex forensic cases by providing a level of discrimination not achievable utilising traditional forensic techniques. The focus of the research was on ammonium nitrate (AN), a common oxidiser used in improvised explosive mixtures.The potential value of IRMS to attribute Australian AN samples to the manufacturing source was demonstrated through the development of a preliminary AN classification scheme based on nitrogen isotopes. Although the discrimination utilising nitrogen isotopes alone was limited and only relevant to samples from the three Australian manufacturers during the evaluated time period, the classification scheme has potential as an investigative aid.Combining oxygen and hydrogen stable isotope values permitted the differentiation of AN prills from three different Australian manufacturers. Samples from five different overseas sources could be differentiated utilising a combination of the nitrogen, oxygen and hydrogen isotope values. Limited differentiation between Australian and overseas prills was achieved for the samples analysed.The comparison of nitrogen isotope values from intact AN prill samples with those from post-blast AN prill residues highlighted that the nitrogen isotopic composition of the prills was not maintained post-blast; hence, limiting the technique to analysis of un-reacted explosive material. 相似文献

Increasing numbers of women have become sex workers, maids, or employees in export production networks—all largely female sectors—to earn incomes in the restructured global economy. Many must migrate domestically and internationally. Women encounter many risks and much insecurity in these sectors: low wages, no benefits, long hours, harassment, health hazards, and lack of rights or legal recourse. By examining work in these three sectors simultaneously, we find that, as a result of globalization, economic restructuring, and crises, 1) women have increasingly been forced into such income-earning activities and 2) many governments have been pushed into strategies that foster these occupations. 相似文献

Testing for drugs in hair raises several difficulties. Among them is the interpretation of the final concentration(s). In a post‐mortem case, analyses revealed the presence of furosemide (12 ng/mL) in femoral blood, although it was not part of the victim's treatment. The prosecutor requested our laboratory to undertake an additional analysis in hair to obtain information about the use of furosemide. A specific method was therefore developed and validated to identify and quantify furosemide in hair by UHPLC‐MS/MS. After decontamination of 30 mg of hair, incubation in acidic condition, extraction with ethyl acetate, the samples were analyzed by UHPLC‐MS/MS. Furosemide was found in the victim's hair at 225 pg/mg. However, it was not possible to interpret this concentration due to the absence of data in the literature. Therefore, the authors performed a controlled study in two parts. In order to establish the basis of interpretation, several volunteers were tested (four after a single 20 mg administration and twenty‐four under daily treatment). The first part indicated that a single dose is not detectable in hair using our method. The second part demonstrated concentrations ranging from 5 to 1110 pg/mg with no correlation between dosage and hair concentrations. The decedent's hair result was interpreted as repeated exposures. In the case of furosemide analysis, hair can provide information about its presence but cannot give information about dosage or frequency of use. 相似文献

This article describes the Danish system, tracing its roots from the days when the crown dealt with all matters involving the family. The role of the amtmen in granting divorce through this administrative process is described. A total of 94% of all divorces in Denmark are handled through this procedure. 相似文献

In their interactions with citizens, police officers are prohibited from (1) using unnecessary Force, (2) Abusing their authority, (3) speaking Discourteously, or (4) using Offensive language, all captured by the acronym FADO. However, acts of police misconduct are complex social phenomena that involve both following legal guidelines and responding to extralegal or mitigating circumstances. Using a factorial survey of police‐civilian interactions that introduce various dimensions of FADO and surrounding circumstances, respondents are asked to rate from zero to ten the seriousness of police misconduct in an encounter. Findings show that respondents' judgments of the seriousness of misconduct consider both legal and extralegal dimensions. On the legal side of the ledger, officers' unnecessary use of force and use of offensive language significantly increase judgments of serious misconduct; on the extralegal side of the ledger, civilians' confrontational demeanor significantly reduces judgments of serious misconduct. The findings suggest that citizens expect officers to behave professionally, or by the book, but with a recognition that “street‐level” discretion has a place in an officer's toolkit. Citizens' expectations that street‐level discretion has its place is also demonstrated by findings for the dimension abuse of authority: Abuse or threatening behavior by officers is not a significant predictor of serious police misconduct. In addition, characteristics of the respondents explain propensities to observe different degrees of police misconduct. Controlling for the social status, political orientation, and prior experience of respondents with the police, we find that (1) blacks rate police misconduct significantly higher than their white counterparts, and (2) liberals rate police misconduct significantly higher than their conservative counterparts. Differences in judgments by blacks and whites and by liberals and conservatives concerning judgments of police misconduct have important implications for the legitimacy of police authority. 相似文献

One of ATP’s legislated mandates is to accelerate industry’s development and commercialization of new technologies. This survey
of 28 projects funded in 1991 found that ATP helped cut technology development cycle time by 50% in most cases. Slightly more
than half of the interviewees provided quantitative estimates of the economic value of reducing cycle time by a single year.
Most interviewees expected the positive impact on cycle time experienced in the applied-research stage to flow through to
later stages in the technology development cycle allowing them to enter the marketplace more quickly. Cycle-time improvements
in other technology development projects were attributed by the companies to their ATP project. Two types of acceleration
were implied: (1) overcoming delays in starting technology development projects, and (2) speeding up performance of research
once it is under way.
