Deterrence lies at the heart of the criminal justice system and policy. There is a lack of information on citizen??s perceptions regarding a critical element of the deterrence process as it manifests through the communication of sanction threats. This study uses data from over 400 adults to examine their knowledge regarding the probability of detection and the average punishments for DUI, and also assesses the contribution of demographic and theoretical variables in predicting perceptions of detection probabilities and punishment estimates. Results show that persons over-estimate the likelihood of detection and provide higher estimates for average sentence lengths, but very few variables predict deterrence perceptions. An investigation of the resetting effect shows that persons tend to lower the estimated likelihood of punishment after experiencing a punishment. Deterrence may work better if researchers and policy officials understand what influences these perceptions and how they may be modified. 相似文献

For street samples suspected of containing the phosphodiesterase-5 inhibitors sildenafil (Viagra(?)) and/or vardenafil (Levitra(?)), including powders or adulterated herbal supplements, a chemical analysis is needed to provide confirmatory identification of these illegally procured substances. Sildenafil and vardenafil are structurally similar and it is difficult to differentiate between them, as previous mass spectrometric studies have shown the two drugs to produce similar fragmentation patterns. The use of tandem mass spectrometry can produce confirmatory data, but the technique requires a high level of technical expertise. We have developed an electrospray ionization-liquid chromatography-mass spectrometry (ESI-LC-MS) method that allows differentiation between these two structurally similar molecules via in-source fragmentation in combination with an ion trap mass spectrometer. A very stable gas phase ion is formed during in-source fragmentation of vardenafil; the combination of the stability of this ion and the longer residence time for the ion in the ion trap results in a very strong signal. This feature results in a method that can provide clear differentiation between sildenafil and vardenafil while at the same time requiring less expertise from the routine analyst to confirm the presence or absence of the two compounds. 相似文献

Animal-scavenging alterations on human remains can be mistaken as human criminal activity. A 32-day study, documenting animal scavenging on a human cadaver, was conducted at the Southeast Texas Applied Forensic Science facility, Sam Houston State University, Huntsville, Texas. A Stealth Cam Rogue IR was positioned near the cadaver to capture scavenging activity. An atypical scavenger, the bobcat, Lynx rufus, was recorded feeding on the cadaver. Scavenging by bobcats on human remains is not a predominant behavior and has minimal documentation. Scavenging behaviors and destruction of body tissues were analyzed. Results show that the bobcat did not feed on areas of the body that it does for other large animal carcasses. Results also show the bobcat feeds similarly during peak and nonpeak hours. Understanding the destruction of human tissue and covering of the body with leaf debris may aid forensic anthropologists and pathologists in differentiating between nefarious human activity and animal scavenging. 相似文献

The recent cycle of social struggles against precarity in Italy has been characterized by an extensive use of images representing precarious workers. This contribution explores this in the case of the Euro Mayday Parade (EMP) protest campaign. The subversion of existing popular culture traditions was the main objective of the activists' newly created icons such as San Precario, Serpica Naro and other visual tools. The visual work on gender in the EMP seemed to fill a gap between theoretical work on the feminization of affective and immaterial labour and the less predominant presence of gender. Visual icons seem to have been at least as successful as text messages in publicizing the precarity discourse and their production deserves further attention. 相似文献

The capability of Fourier transform infrared (FTIR) spectroscopic imaging to provide detailed images of unprocessed latent fingerprints while also preserving important trace evidence is demonstrated. Unprocessed fingerprints were developed on various porous and nonporous substrates. Data-processing methods used to extract the latent fingerprint ridge pattern from the background material included basic infrared spectroscopic band intensities, addition and subtraction of band intensity measurements, principal components analysis (PCA) and calculation of second derivative band intensities, as well as combinations of these various techniques. Additionally, trace evidence within the fingerprints was recovered and identified. 相似文献

Crime dramas provide entertainment to millions of Americans. The impact of viewing these programs on perceptions and expectations of police is a concern for practitioners, researchers and policy makers. While a growing body of research is identifying factors associated with the probability of clearance in offenses reported to police, a dearth of research looks at the portrayal of police efficiency in apprehending offenders in popular crime dramas. This study examines the depictions of police investigations across four fictional crime dramas. The authors find offenses are cleared at much higher rates than national averages and that several case characteristics typically associated with clearance in actual cases do not share the same relationship in these fictional programs. Results indicate substantial variation between programs in the depiction of the collection and utility of DNA evidence in assisting investigators to identify suspects. Findings are discussed in relation to data collected from actual police departments. 相似文献

While negative attributions are often made toward female victims of domestic violence, studies have not explored whether attributions shift contingent upon whether women stay with or leave abusive husbands. Further, no studies investigated whether negative attributions decrease if the participants receive information about the prevalence of domestic violence or the risks inherent in leaving an abuser. Therefore, two studies were designed that investigated attributions made by young adults when women either stay with or leave an abusive husband and whether educating the participants about prevalence of domestic violence and risks of leaving mitigate negative judgments. In both studies, young adults responded to surveys assessing attributions toward a female heterosexual victim of domestic violence. Results indicated that participants made more positive attributions about her personality characteristics and parenting ability if a woman left the relationship. Informing students beforehand about potential risks of leaving and personal experience with domestic violence did not erase this effect, but interactions mitigated some of the effects. Results suggest that educating young adults about risks of violence while useful, is not sufficient to change blaming attitudes. Educators may instead need to challenge the attribution process. Further research involving attributions toward gay and lesbian victims of domestic violence is suggested. 相似文献

In the mid-2000s, Beijing made a series of unilateral trade concessions with respect to agricultural trade with Taiwan. This move distressed the then incumbent party of the Republic of China, the Democratic Progressive Party (DPP), because Beijing’s offers might weaken the DPP’s rural support. This article offers the first empirical assessment of Beijing’s trade concessions. Using an original and highly disaggregate dataset at the township-product level, it examines what types of regions were more likely to be the beneficiary of the trade concessions, whether the concessions caused any production change, and the extent to which these changes undermined the DPP’s electoral support. It is found that while the benefit of tariff concession was not confined to pro-DPP regions, the townships that grew tariff-reduced products were no less likely to vote for the DPP. The result suggests a limit of Beijing’s economic enticement. 相似文献
