The use of three analytical techniques for forensic investigation of synthetic polymers is described. These techniques are: pyrolysis infrared spectrometry (PyIR), pyrolysis gas chromatography (PyGC) and energy dispersive X-ray micro probe analysis (EPMA). Whereas the first two methods have been described previously, the microanalytical procedure is new. It may be used in combination with one of the other two techniques for the discrimination between polymer samples.  相似文献

Although juvenile drug courts (JDCs) have now been in operation for 17 years, there is still no definitive appraisal as to this model's cost effectiveness and in particular, no detailed cost analysis of a JDC program following the 16 strategies until this one. The cost data presented in this paper build on the process and outcome evaluations performed on the Clackamas County Juvenile Drug Court (CCJDC). The criminal justice costs incurred by participants in drug court are compared with the costs incurred by eligible non‐participants. CCJDC participants had far more positive outcomes than those who did not participate in the program. In the two years after drug court entry, CCJDC participants cost the taxpayers $961 less per participant than similar individuals who did not attend the drug court program.  相似文献

Although studies on drug dealing have examined techniques sellers use to ensure against undercover infiltrations, none has explored the use of such techniques at the interactional level. The objective here is to address this void by exploring the perceptual shorthand dealers use to determine whether buyers in question are undercover. This perceptual shorthand processes one of two types of deception clues in making this judgment: trend discontinuity and interpersonal illegitimacy. Trend discontinuity is associated with police in formants and results from situations in which (I) familiar customers suddenly introduce unfamiliar others who wish to buy drugs and (2) familiar customers suddenly and signifcantly increase quantities they themselves desire to purchase. Interpersonal illegitimacy is associated with undercover agents and results from situations in which unfamiliar buyers emit certain physical and verbal “vibes” believed to be indicative of covert law en forcement personnel. Discussion focuses on the data's presuppositional and microstructural implications for restrictive deterrence (Gibbs, 1975). Data were drawn from semi-structured interviews with 32 semi-institutionalized heroin user-dealers located in a very large western US. city.  相似文献

The Kyoto Protocol envisages the use of various instruments to achieve emission reduction targets, one of which is the European Union Emission Trading Scheme (EU ETS), the most important market worldwide for CO2 emission allowances. The volume of European Union Allowances traded represents over 45% of all the carbon dioxide generated by human activity within the continent. In its first two phases (2005–2012), the behaviour of the EU ETS was erratic, as a result of discretionary policies, an oversupply of allowances and reduced economic activity due to the global crisis. These factors caused excessively low prices that distorted the initial goals of achieving low-carbon solutions. From 2013, changes were made to the market regulation mechanisms in order to correct these structural deficiencies. Empirical analysis of daily prices in the two central phases of the market, following the pattern of ARCH and GARCH models, shows that the measures taken within the EU generated greater confidence and stability in the market and thus reduced volatility. Subsequent price behaviour, following a bullish path, has confirmed the success of the measures taken and their contribution to fulfilling emission reduction targets.  相似文献

This paper describes a repeatability test, comparing conventional X-ray diffraction (XRD) analyses with the technique of quantitative X-ray diffraction (QXRD) as a determinant of mineral abundance. The conjunctive use of both methods allows specific mineral abundances to be matched between scene of crime (SOC) and suspects where soil or substrate mineralogy is similar. In our test, samples from potential SOC locations were taken from car tyre tracks. A car was driven to one location by an independent person and the car submitted for sampling. The tyre-tread sample showed potential correlation to two locations: one correct and the other incorrect. QXRD showed the mineral proportions of the tyre-tread sample matched only the correct location. However, QXRD did fail to discriminate two locations that XRD did show to be different. Both methods utilise the same sample and X-ray diffractogram, suggesting that their conjunctive use, preceded by standard Earth material forensic study, is recommended.  相似文献

The theme of the crisis of Russian society continues to occupy a leading place in our publications. However, the economic woes clearly felt by all have meant that discussions have been predominantly, if not exclusively, concerned with the economic component of the crisis. The reasons for the failures in this sphere are often sought in subjective weaknesses, in our habitual revealing of the "sources of evil," whether these be specific persons (Yeltsin and Gaidar, Chernomyrdin and Zaveriukha, Khasbulatov and Rutskoi), entire groups (the "nomenklatura" the "red—browns," the "agrarians," the "democrats," the "monetarists"), or external forces ("imperialists," "freemasons"), and so on. Accordingly, the solutions to the crisis are also quite simple: one need only replace an "incorrect" program with a "correct" one, remove the "sources of evil" and "agents of influence" from power, then all the problems will resolve themselves (by spring or fall, in a year or two, depending directly on the temperament of the particular healer of society and inversely on the degree to which he is informed).  相似文献

This article examined how to elicit cues to deception when a suspect is asked both about his/her intentions and his/her corresponding past planning, and when the investigator holds evidence on the suspect’s planning activities. In a new experimental set-up accommodating the main characteristics of intent, participants (N = 120) either planned a criminal or a non-criminal act. They were intercepted before completing the planned act. Each participant was interviewed in accordance with one of three interview techniques: Early Evidence disclosure or one of two versions of the Strategic Use of Evidence (SUE) technique. All the interviews were transcribed and scored for consistency. As predicted, the liars were perceived as having a higher degree of inconsistency for two of the three relevant comparisons (Statement on Planning–Evidence on Planning; Statement on Intent–Evidence on Planning). Furthermore, using the evidence strategically resulted in differences between liars and truth tellers being magnified, as predicted. This article advances previous findings in showing that by interviewing strategically with respect to the evidence, it is possible to elicit reliable cues to deception when a suspect is asked about intentions and corresponding planning activities.  相似文献

The prison crowding problem in the United States has been described by the Department of Justice as one of the most critical problems facing the criminal justice system (Gettinger, 1984). During the past several years numerous state and federal, public and private task forces and advisory groups have proposed solutions to the crisis but, as of yet, the proposals advanced by criminal justice policy analysts have done little to ease the crowding crisis. In light of the failure of various planning groups to deal with the problem of crowding, this paper examines how the correctional systems have coped with prison crowding through the use of shortterm ad hoc solutions during the 1980s.  相似文献

Crisis simulation is by definition an exercise in cognitive structuring. It is argued that this automatically entails a search for heuristics and organizational decisions which might render complex, highly interactive social and technological situations comprehensible, hopefully amenable to being programmed and, ultimately, controlled. In this paper, a cognitive analysis is presented of alternative paths available to an organization that is in a crisis state to move away from crisis back to more routine modes of operation. Cognitive mapping of plausible post-crisis decision-paths results in a multi-path scheme that enables one to comprehend, even assess, the erratic development of political and socio-technological events in a post-crisis period. The specific example that is used to illustrate the applicability of such a multi-path scheme concerns the revival of NASA following the Space Shuttle disaster. In contrasting the cognitive opportunities in post-crisis situations with the cognitive failures implicit in pre-crisis settings, the multi-path simulation technique enables a more sophisticated understanding of the dynamics of crisis development.  相似文献

Recent work on incidental findings, concentrating on the difficult problems posed by the ambiguous results often generated by high-tech medicine, has proceeded largely independently from recent work on medical researchers' ancillary-care obligations, the obligations that researchers have to deal with diseases or conditions besides the one(s) under study. This paper contends that the two topics are morally linked, and specifically that a sound understanding of ancillary-care obligations will center them on incidental findings. The paper sets out and defends an understanding of ancillary-care obligations, which is based on the idea that when participants signed up for a study they may -- independently of their beliefs and expectations and of those of the researchers -- be taken to have partially entrusted certain aspects of their health into the researchers' hands. This partial entrustment model of ancillary-care obligations, in turn, has substantive implications for how to deal ethically with incidental findings; for instance, it suggests that researchers have no moral obligation to hunt for incidental findings.  相似文献

Purpose. Supporting Offenders through Restoration Inside (SORI) is a programme that aims to: increase victim empathy in offenders; motivate offenders to change their offending behaviour; and to take personal responsibility for the harm that he has caused. A 5‐day course based on the SORI principles has been piloted across seven prison sites in the UK. The aim of the study reported here was to evaluate the effectiveness of the programme across these sites. Methods. Three psychometric questionnaires [Victim Concerns, Locus of Control, and Stages of Change (SoC) scales] were administered to the participants immediately before and after the programme had taken place (data were available for 131 participants for the Victim Concern Scale, 82 participants for the Locus of Control measure, and 96 participants for the SoC questionnaire). These psychometric measures were the primary research outcome. Statistical analyses were employed to assess whether any changes had been effected by the programme. Results. The results of this study found that: participants had an enhanced victim concern for all types of victims, were more motivated to change their offending behaviours, and were more willing to take responsibility for their actions, after completion of the course. No change was found in terms of participants seeing themselves as being more in control of their actions/environment. Conclusions. The results lend support for the notion that the 5‐day SORI course is effective in increasing participants’ levels of victim concern and motivation to change, while not really impacting upon levels of ownership for one's ownership for one's actions. Suggestions for future research and limitations of the study are discussed in the paper.  相似文献

The objective of this study was to determine the prevalence of physical and emotional abuse in Portuguese juvenile dating relationships and to investigate attitudes about these forms of violence. A sample of 4,667 participants, aged 13 to 29 years, completed two questionnaires, one behavioral and one attitudinal. At least one act of abuse perpetrated by a dating partner during the previous year was reported by 25.4% of participants (13.4% reported to have been victims of physical abuse and 19.5% of emotional abuse). Abuse of a partner was reported by 30.6% of participants; at least one act of physical abuse was reported by 18.1% and of emotional abuse by 22.4%. The attitudinal data revealed, however, a general disapproval of violence use. Violence support was higher among males, participants with lower educational and social status and those who had never been involved in a dating relationship. Women reported more acts of partner abuse than males; no gender differences were found regarding self-reported victimization. Both perpetration and victimization were reported more by older students. Although university students tend to report more acts of general and emotional abuse against their partners, students from professional schools are more represented among both perpetrators and victims of physical and severe violence. The best predictors of violence were educational status and attitudes toward partner.  相似文献

This paper explores the implications of the expansion of judicial and therapeutic roles in a drug treatment court (DTC) in Canada. Issues that are raised are: how the courtroom is framed as a therapeutic space where public appearances by participants are part of the therapeutic process; how judges have taken on therapeutic practices, effectively compromising their traditional role as neutral arbiter; how certain women resisted therapeutic interventions by judges and felt they received harsher punishments than men; and how treatment counselors in DTCs are given powers of enforcement over their clients. The collision of judicial and therapeutic roles in the DTC results in negative consequences for individuals in the specialized courts. Specifically, DTC participants are expected to engage in a therapeutic relationship with their treatment counselors and the court; however, their right to confidentiality is withheld, and their treatment counselors act as agents for the court.  相似文献

Two experiments explore the effect of law enforcement officers’ communication errors and their response strategies on a suspect’s trust in the officer; established rapport and hostility; and, the amount and quality of information shared. Students were questioned online by an exam board member about exam fraud (Nstudy1 ?=?188) or by a police negotiator after they had stolen money and barricaded themselves (Nstudy2 ?=?184). Unknown to participants, the online utterances of the law enforcement officer were pre-programmed to randomly assign them to a condition in a 2(Error: factual, judgment)?×?3(Response: contradict, apologize, accept) factorial design, or to control where no error was made. Our findings show that making (judgment) errors seem more detrimental for affective trust and rapport in a suspect interview, while no such effects appeared in a crisis negotiation. Notably, we found a positive effect of errors, as more information was being shared. The ultimate effect of the error was dependent on the response: accept was effective in re-establishing rapport and decreasing hostility, while contradict threatens it. Accept seems more effective for the willingness to provide information in a suspect interview, while apologize seems more effective for affective trust and rapport in a crisis negotiation.  相似文献

The general inadequacy of the sources of data in criminal justice for evaluation and planning has been apparent for some time. Among those factors which contribute to the inadequacy of much crime data are the following: (1) generally it is limited to one particular stage of criminal processing; (2) measurements are in the form of summary statistics; (3) it is specific to one agency in that each collects and reports its own summary tabulations; (4) the unit of count changes with different organizational structures. In sum, existing sources of data frequently measure only one temporal point and this fails to reflect the dynamic aspects of criminal processing. Similarly, many of the analytic techniques used for evaluation are static and do not reflect the dynamic aspect of the system.

In light of such considerations, this paper explores the utility of various dynamic-analytic techniques in conjunction with longitudinal sources of data. The following include some of the more important implications for future evaluation. First, the development of a sophisticated systems model to assist in the selection and verification of outcome measures. Second, a reconceptualization of the outcome measures normally used in evaluation studies in order to conceive of the total system as a critical outcome measure in evaluative studies. Third, the development of a model to assist in the planning process that precedes evaluation. This may be accomplished by providing a mechanism for the simulation of change, thus predicting the future impact of changes in the system.  相似文献

An inkless set of finger and palm impressions has been obtained on thermochromatic paper by incorporating the protic solvent butylene glycol into a base hand cream mixture, which is rubbed into the hands for 30 sec before donation. This requires no washing of the hands before or after donation, removing many of the difficulties associated with inked impressions. In a random trial of 50 male and 50 female participants (mean age 41 years), 96 found the hand cream pleasant and easy to use and all produced identifiable finger and palm impressions. Following donation, participants continued to rub the hand cream into their hands. Impressions were visible immediately after donation and have not exhibited fading 2 years after being taken. 10% of participants produced impressions that captured third‐level detail, the variation between participants being thought to be associated with the amount of pressure applied during donation.  相似文献

The ability to estimate accurately from known parameters is a fundamental aspect of science and is evident as an emerging approach in the area of footprints and stature estimation within the field of forensic identification. There are numerous foot dimensions that have been measured in the literature to predict stature with varying degrees of confidence but few studies have tried to link the strength of estimation to anatomical landmarks. Such an approach is utilised in this study which estimates stature from the right footprints of sixty one adult male and female UK participants. Static and dynamic footprints were taken from each volunteer using the 'inkless paper system'. The prints were digitised and twelve length, width and angle measurements were chosen for the analysis. The highest correlations with stature were shown to be the heel to fourth toe print for the static group of footprints (r=0.786, p<0.01), and the heel to fifth toe print in the dynamic footprints (r=0.858, p<0.01). Collinearity statistics suggest the heel to fifth toe print length measurement is independent and not influenced by any other variables in the estimation of stature for the dynamic prints. Linear regression equations for this measurement presented the smallest standard error of estimate (SEE) and highest shared variance (R(2)) of all included variables (SEE 4.16, R(2) 0.74). Our study discusses a potential anatomical explanation as to why the lateral border of the foot and hence the impression it makes upon a hard surface, is a more stable indicator in the estimation of stature. The investigation recommends the use of Calc_A4 and Calc_A5 length measurements when estimating stature from footprint impressions.  相似文献

Drug screening through urinalysis is a widely accepted tool for rapid detection of potential drug use at a relatively low cost. It is, therefore, a potentially useful method for detecting and monitoring drug use in a variety of contexts such as the criminal justice system, pre-employment screening and a variety of treatment centers. This article explores the efficacy of two commercially available drug-screening assays: Online KIMS assay (Roche) and EMIT II assays. First, we evaluate the sensitivity and specificity of two immunoassays. A total of 738 urine samples were collected among adult arrestee populations from Chicago, New Orleans and Seattle through the Arrestee Drug Abuse Monitoring (ADAM) program. Partial samples were split within one laboratory and analyzed by both enzymes multiplied immunoassay technique (EMIT) II and kinetic interaction of microparticle in solution (KIMS) assays for a 10-drug panel (amphetamine, barbiturates, benzodiazepines, marijuana, cocaine, methadone, methaqualone, opiate, phencyclidine and propoxyphene). Gas chromatography-mass spectrometry (GC-MS) was used as a confirmation method for all positives from either EMIT II or KIMS for all experiments. Second, the paper examines whether using different testing laboratories plays a role in the final results. The same experiments were repeated at two different testing locations: one in California and one in London and England. Third, the paper studies whether drug testing results vary between two laboratories when each of them had used their own routine screening method: the Forensic Science Service (FSS) at Birmingham, United Kingdom with KIMS assay and Medscreen Limited at London, United Kingdom with EMIT II. In summary, both EMIT II and KIMS assays generate fairly consistent results. The concordance rate against each of the 10 drugs tested is relatively high (97.4-100%). The discrepancies, in most cases, occurred at drug concentrations near the cut-off levels. There were more discrepant results between two laboratories compared to when specimens were analyzed at the same laboratory using two different assays.  相似文献
