This Article examines the idea of betraying or being disloyal to one’s own country as a matter of criminal law. First, the
Article defines crimes of disloyalty as involving failures to prioritize one’s own country’s interests through participating
in efforts to directly undermine core institutional resources the country requires to protect itself or otherwise advance
its interests by force. Second, this Article canvasses various potential arguments for the existence of a duty not to be disloyal
to one’s own country and argues that they fail. Finally, this Article argues that we should interpret the wrong of disloyalty
crimes as involving not betrayal or infidelity, but transgression of political boundaries. That is, the relevant wrong here
is rooted in the ideas of separation of powers and assignments of roles between citizens and the state, and we should thus
conceive crimes of disloyalty as crimes of usurpation and evaluate the moral rights and wrongs of such crimes accordingly. 相似文献

Impurities in 48 methamphetamine (MA) samples were analyzed by liquid-liquid extraction (LLE) and headspace solid-phase microextraction (HS-SPME) methods. MPS-2 autosampler was used to improve reproducibility of SPME method, and nonadecane (C(19)) diluted with potassium bromide (KBr) powder was used as an internal standard for standardizing retention time. Impurities identified by SPME method showed different patterns compared with LLE method. Non-volatile impurities like methamphetamine dimer were not identified by SPME method, but some volatile impurities like diphenylketone, caprolactam and lots of unknowns were identified only by SPME method. 1-Phenyl-2-propanone (P2P), 1-phenyl-2-propanol and benzylcyanide peaks could be discriminated clearly by SPME method without interference of amphetamine, an artifact originates from MA degradation. Differences in the impurity patterns resulted in different clustering results. When 48 MA samples were classified into 5 LLE and 5 SPME clusters, cross-matching of the clusters resulted in 8 sub-clusters. It shows that combination of the different extraction methods can distinguish the differences which cannot be distinguished by LLE or SPME method alone, and can improve reliability of the profiling results. 相似文献

This study uses an ecological systems theory to understand bullying behavior. Emphasis is given to overcome limitations found in the literature, such as very little empirical research on functions of parental involvement and the impacts of school climate on bullying as an outcome variable. Two functions of parental involvement investigated are (a) bridging the negative experiences within the family with bullying behaviors at schools, and (b) influencing school climate. Bullying behaviors were measured by a modified Korean version of Olweus' bully/victim questionnaire (reliability range: .78-.84) from 1,238 randomly selected Korean middle school students in 2007. Findings from structural equation modeling (SEM) analyses showed that (a) individual traits are one of the most important influence on bullying, (b) negative experiences in the family do not have direct influence on bullying behaviors at school, (c) parental involvement influences school climate, and (d) positive school climate was negatively related to bullying behaviors. 相似文献

The article is a summary of the development of the District of Columbia Superior Court's Fathering Court Initiative. The Fathering Court Initiative is a problem‐solving court that has developed an innovative approach to child support cases that involves noncustodial parents returning from a period of incarceration. The program is designed to operate as a court based partnership between government and private sector organizations that match resources with family needs to promote responsible co‐parenting. 相似文献

The ability to properly collect, analyze and preserve biological stains is important to preserving the integrity of forensic evidence. Stabilization of intact biological evidence in cells and the DNA extracts from them is particularly important since testing is generally not performed immediately following collection. Furthermore, retesting of stored DNA samples may be needed in casework for replicate testing, confirmation of results, and to accommodate future testing with new technologies.A novel room temperature DNA storage medium, SampleMatrix™ (SM; Biomatrica, Inc., San Diego, CA), was evaluated for stabilizing and protecting samples. Human genomic DNA samples at varying amounts (0.0625-200 ng) were stored dry in SM for 1 day to 1 year under varying conditions that included a typical ambient laboratory environment and also through successive freeze-thaw cycles (3 cycles). In addition, spiking of 1-4× SM into samples prior to analysis was performed to determine any inhibitory effects of SM. Quantification of recovered DNA following storage was determined by quantitative PCR or by agarose gel electrophoresis, and evaluation of quantitative peak height results from multiplex short tandem repeat (STR) analyses were performed to assess the efficacy of SM for preserving DNA.Results indicate no substantial differences between the quality of samples stored frozen in liquid and those samples maintained dry at ambient temperatures protected in SM. For long-term storage and the storage of low concentration samples, SM provided a significant advantage over freezer storage through higher DNA recovery. No detectable inhibition of amplification was observed at the recommended SM concentration and complete profiles were obtained from genomic DNA samples even in the presence of higher than recommended concentrations of the SM storage medium. The ability to stabilize and protect DNA from degradation at ambient temperatures for extended time periods could have tremendous impact in simplifying and improving sample storage conditions and requirements. The current work focuses on forensics analysis; however this technology is applicable to all endeavors requiring storage of DNA. 相似文献

The Role of Emotional Security,Narrative, and Resilience for Youth and Families in Contexts of Armed Conflict 下载免费PDF全文
The far‐reaching devastation created by contemporary armed conflict puts children and families at risk. The goal of this article is to describe current research on the effects of armed conflict and political violence on families and youth with a focus on the roles of emotional insecurity and narratives of conflict that can persist long after the end of conflict. We describe how identity processes that are at the heart of many intergroup conflicts of the 20th and 21st centuries are linked with emotional insecurity and the historical and personal narratives of youth in these contexts. We conclude with general considerations for legal, medical, and mental health practitioners working with families who have experienced armed conflict. 相似文献

Although there is considerable research on Caucasian sexual offenders, there has been much less research on sex offenders of Asian heritage. The current study compared East Asian (e.g., Chinese, Japanese, and Korean) sex offenders in British Columbia (B.C.), Canada, and other B.C. sex offenders on items and total score of Static-99R. This study included all provincially sentenced adult male sexual offenders (n = 4580) supervised in the community by B. C. Corrections (including 122 East Asian sex offenders). Sexual, violent, any crime, and any recidivism (including technical violations) data were collected with an average follow-up 4.3 years. The total scores of Static-99R were similar between East Asian sex offenders and other ethnic groups (M = 2.0 vs. M = 2.4). East Asian offenders scored significantly lower than other ethnic offenders on several items measuring general criminality (e.g., prior non-sexual violence, prior sentencing dates, and any prior sex offenses). In contrast, Asian offenders appeared to be more paraphilic (e.g., any convictions for non-contact sex offenses). Lastly, Static-99R significantly predicts sexual, violent, and criminal among sex offenders of East Asian heritage. 相似文献

The current study focuses on predominant predictors associated with men’s and women’s engagement in driving under the influence (DUI) in an attempt to determine whether gender-specific interventions would be more affective at reducing impaired vehicle operation. A male-only subsample (n?=?863) and a female-only subsample (n?=?975) from a survey administered at a large Southeastern university containing self-reported measures of DUI were used to evaluate gender differences in motivations and correlates of DUI behavior. A series of logistic regressions containing indicators drawn from theories of deviant behavior (e.g., Akers’ social learning theory (SLT) and Gottfredson and Hirshi’s low self-control (LSC) theory) yield results indicating that differential association and imitation, both factors associated with SLT, are significant predictors for both gender cohorts’ DUI behavior. Low self- control was a significant predictor within female-only models, but not the final male-only models. This suggests that peer associations and modeling may be targets of intervention generally, but that, as it relates to DUIs, women may particularly benefit from programs focused at limiting impulsivity and risk-taking behavior as these are components of Gottfredson and Hirschi’s LSC construct. 相似文献

Postmortem fingerprint collection is a routine part of many forensic death investigations. Although the production of postmortem prints is usually straight forward, several obstacles and scenarios can make the collection difficult. A common challenge occurs when finger pads are mummified. Several current techniques allow for softening and rehydration of mummified finger pads; however, despite the employment of such techniques, the production of adequate postmortem fingerprints can remain elusive. The authors present two techniques that can improve the chances of obtaining suitable fingerprints from mummified remains. The “baby powder method” involves applying a cornstarch‐based powder, such as baby powder, onto the darkened and mummified finger pads, to allow better visualization of the fingerprint detail. The “transillumination method” involves carefully dissecting away the tissues underlying the finger pad, followed by placement of a bright light source underneath the finger pad, such that the finger ridge pattern is illuminated. 相似文献

Racial disproportionality has been a longstanding issue within child welfare. The continued overrepresentation of black children in the foster care system is troubling. The authors of this article conducted a case study of two counties in New York State that have steadily decreased the number of black children in foster care in an effort to identify what aspects of their child welfare practice impacted the decline. The case study employed document analysis, in-depth interviews, and focus groups with child removal decision makers. Utilizing a grounded theory approach to content organization and analysis, several themes emerged as noticeable factors. Some of the most salient themes included preventive services and resources, community collaborations, case practice development, family meetings, workforce diversity, the court system, and, the most unique, blind removal meetings. The themes found in this study present promising practices to assist in decreasing the racial disparity in child welfare removal decisions. 相似文献
