While canines are most commonly trained to detect traditional explosives, such as nitroaromatics and smokeless powders, homemade explosives (HMEs), such as fuel–oxidizer mixtures, are arguably a greater threat. As such, it is imperative that canines are sufficiently trained in the detection of such HMEs. The training aid delivery device (TADD) is a primary containment device that has been used to house HMEs and HME components for canine detection training purposes. This research assesses the odor release from HME components, ammonium nitrate (AN), urea nitrate (UN), and potassium chlorate (PC), housed in TADDs. Canine odor recognition tests (ORTs) were used with analytical data to determine the detectability of TADDs containing AN, UN, or PC. Headspace analysis by gas chromatography/mass spectrometry (GC/MS) with solid-phase microextraction (SPME) or online cryotrapping were used to measure ammonia or chlorine, as well as other unwanted odorants, emanating from bulk AN, UN, and PC in TADDs over 28 weeks. The analytical data showed variation in the amount of ammonia and chlorine over time, with ammonia from AN and UN decreasing slowly over time and the abundance of chlorine from PC TADDs dependent on the frequency of exposure to ambient air. Even with these variations in odor abundance, canines previously trained to detect bulk explosive HME components were able to detect all three targets in glass and plastic TADDs for at least 18 months after loading. Detection proficiency ranged from 64% to 100% and was not found to be dependent on either age of material.  相似文献

The Strategic Use of Evidence (SUE) approach is a framework for planning and executing suspect interviews with the aim of facilitating judgments of truth and deception. US law enforcement officers (N = 59) either received training in the SUE approach or did not. Each officer interviewed a mock suspect (N = 59) who had either committed a simulated security breach or had completed a benign task. The officers who received SUE training interviewed in line with the training: They questioned the suspect systematically, withheld the evidence and critical case information until after questioning, and relied on statement-evidence inconsistency to detect deceit. Consequently, SUE-trained interviewers achieved a higher deception detection accuracy rate (65%) compared to untrained interviewers (43%).  相似文献

Social rights are essential to our ability to fully participate in society. In Latin America, these rights are increasingly marginalized as neoliberal policies take hold. At the same time, the related concepts of civil society and social capital are often incorporated into strategies aimed at alleviating the problems of the Latin American poor. It is expected that by strengthening people's civic capacity, their sense of mutual responsibility and ability to self-provide certain services will be enhanced. In the context of the current policy environment, however, such strategies are unlikely to be entirely successful. Lack of economic resources may preclude the Latin American poor from effective civic participation. More importantly, the promotion of civil society and social capital on the part of aid agencies and governments may represent an implicit threat to social rights, in as much as the organizations advocated are not likely to actively struggle for expansion of rights. Nevertheless, human rights documents such as the Universal Declaration of Human Rights and the Convention on the Rights of the Child provide a base upon which rights-based movements can be constructed.  相似文献

Procedural Justice,Outcome Favorability and Emotion   总被引:3,自引:0,他引:3  
This study investigated the effects of procedural justice on discrete emotional responses. Based upon the cognitive appraisal model of emotion, it was argued that the experience of procedural justice (or injustice) allows individuals to derive meaning from favorable and unfavorable allocation decisions. Thus, procedural justice works with outcome favorability to produce a variety of emotional states. These ideas were tested in a laboratory experiment. As predicted, two happiness-related emotions (happiness and joy) and a sadness-related emotion (disappointment) showed only a main effect for outcome favorability. Two anger-related emotions (anger and frustration) were highest when an unfavorable outcome occurred because of an unfair procedure. Higher levels of guilt and anxiety were reported when an unfair procedure resulted in a favorable outcome. Contrary to predictions, a third happiness-related emotion (pride) showed only a main effect for outcome favorability.  相似文献

Grounded in literature review and an ethnographic study, this article examines contemporary Brazilian domestic life. Relations among women (employers and maids) and between women and men are analyzed with a focus on the home as a space in which gender, race, and class inequalities are constantly reproduced. The article argues that what happens in domestic life is constitutive of wider social divisions and that the domestic is a universe integral to the national social context. A case in point is the connection between the widespread use of paid domestic labor and the naturalization of black women as subservient, complementing the pairing of whiteness and class entitlement. Another case is the buffering role of maids in the development of gender conflicts in well-off homes, thus blurring gender hierarchies at a broader scale. Locating the domestic within the recent discussion on global domestic labor, the article compares particularities of Brazilian domestic life to those elsewhere.  相似文献

To date few reports have provided direct comparison of psychosocial vulnerability and resources among youth with victimization and perpetration histories. Within a racially diverse, high-risk adolescent sample (n = 849), this study undertakes MANCOVA tests on a multidimensional set of risk and protective factors contrasting youth with histories of 1) neither violent victimization nor perpetration, 2) victimization only , 3) both perpetration only, and 4) both victimization and perpetration. All three violence-affected groups reported elevated risk and diminished protection, with perpetrating victims demonstrating the greatest psychosocial impairment. Detailed contrasts among the youth group profiles provide insights regarding overlapping and distinct developmental etiologies and implications for preventive and remedial intervention.  相似文献
