Abstract: The proper identification of illicit plants such as Papaver somniferum L (opium poppy) is important for law enforcement agencies. The identification of opium poppy was presently tested using 10 genetic markers that are universal for all plants or specific to a few poppy plants. The genetic distances of universal markers such as nuclear internal transcribed spacer (ITS), 18S rRNA, plastid rbcL, and trnL‐trnF intergenic spacer (IGS) of 14 species included in the Papaveraceae and Fumariaceae family were acquired by sequence comparisons. Both the ITS region and trnL‐trnF IGS showed high levels of interspecific divergence. Six Papaver genera‐specific markers were developed from coding regions involved in morphine biosynthesis. Three markers (TYDC, NCS, and BBE) produced amplicons only in opium poppy, providing a presence/absence test for opium poppy, while three additional markers (CYP80B1, SAT, and COR) were genus specific. These 10 markers might be useful for the forensic DNA analysis of opium poppy. 相似文献

A growing number of studies in criminal victimization had integrated the individual model and the context model to examine the dynamics of influences from the predictors at different levels. Only a few studies, however, had explored the impact of multilevel factors upon criminal victimization outside the U.S. context. Using the survey data gathered in Seoul, South Korea, the current study tested the applicability of the multilevel approach in criminal victimization to the Korean context. The results were mixed. At the macro level, poverty and community cohesion were positively associated with victimization by street crime and residential crime, respectively. Inconsistent with the findings in the U.S. studies, however, community cohesion increased the chance of residential crime victimization, and residential mobility was not significantly associated with criminal victimization. At the micro level, avoidance behaviors and target hardening efforts were associated with more criminal victimization, contrary to the proposition by opportunity theory. These unexpected findings could be explained by the unique social and cultural characteristics of Korean society. The unique contexts of modern Korean society as well as the limitation of the current study are discussed. 相似文献

The professional boundaries of practice for nurses and midwives are specifically addressed in professional codes of ethics and conduct, employer policies and guidelines and more frequently in the professional literature. There are many forms in which boundary violations and boundary crossings may present or circumstances in which they may occur. This column considers a recent case (involving a bequest to a registered nurse under a will) which came before the Queensland Nursing Tribunal. The decisions of the tribunal, the District Court and the Court of Appeal provide practical guidance to nurses and midwives on the importance of establishing and maintaining the professional boundaries essential to the therapeutic relationship with their patients and clients. 相似文献

This article identifies ways that judges, lawyers, researchers, and policy makers may attend to the role of gender and gender dynamics facing same‐sex couples upon divorce or other relationship dissolution. When same‐sex couples marry, the legal system and society at large may project conceptions of gender onto same‐sex couples, often in a manner that conflicts with couples' intentions and practices. Gender and gender dynamics may affect the bases for dissolution, the financial aspects of dissolution, and the determination of child custody. The article also suggests directions for future research on the impact of gender on the dissolution of same‐sex relationships. 相似文献

In the early days of the Korean War, the U.S. Air Force (USAF) had a policy of precision bombing military targets only. Policy-makers in Washington, D.C., formulated this policy to ensure the protection of Korean civilians and to increase the effectiveness of their air operations. Senior USAF officers in Korea, however, were unhappy about the limitations placed on them by Washington. In their strategic air operations against targets in North Korea USAF officers followed Washington's precision bombing policy, but they insisted that USAF bombers be permitted to use incendiary bombs against population centers in North Korea. China's entry into the war in November 1950 led to a drastic change in the precision bombing policy. On 5 November 1950, when the UN forces began suffering defeat after defeat in battles with the new enemy, General Douglas MacArthur designated cities and villages in North Korea as “main bombing targets” and permitted the use of incendiary bombs, which had been used in attacks against Japanese cities during World War II. From that point until the end of the war, the USAF regarded North Korean cities and villages as their crucial targets as political and military occasion demanded. 相似文献

Abstract A number of accounts of shame and guilt emphasise an association between shame and anger difficulties, and it has been suggested that shame and rage may promote one another. The shame–anger relationship may be particularly relevant to the study of forensic populations, as the fact of having committed a criminal offence has the potential to be a highly shame-provoking experience. The current study investigates the prediction that shame and guilt reactions to an offence are differentially related to the propensity to experience and ability to control anger. A measure of offence-related shame and guilt and a measure of anger experience and control was completed by 60 men detained in forensic psychiatric units. The results supported the prediction that offence-related shame is associated with elevated levels of anger difficulties, whilst offence-related guilt is associated with ability to control anger. The findings of the current study are consistent with those of previous investigations of shame, guilt and anger. Specific implications for the understanding and prevention of violent offending are discussed. 相似文献

Using a unique data source of genealogies of upper-status families, called Bulcheonwye families, we assess how the extent of family succession through adoption changed over five centuries from 1450 to 1949 in Korea. Our analysis shows the continued increase in the share of adopted sons among total family successors up to the end of the 19th century when three out of ten family successors were adopted. The trend of the increasing role of adoption is closely related to the declining number of sons per family, suggesting that not only the rising influence of Confucian culture but also demographic changes increased the demand for adoption. Finally, our comparison provides evidence that the likelihood of achieving high social status was significantly higher among adopted sons than biological ones, suggesting that the socioeconomic potential of adopted sons could be an important factor for adoption decision. 相似文献

While the urban area was increasingly filled with middle- and low-status residents, the rural area was dominated by high-status settlers whose number increased because of migration from the city and natural growth. Remarkable differences existed between urban and rural marriage features such as marriage age and rate of remarriage. The more sincere adoption of the high-status marriage culture in the rural area may be attributed to its occupational homogeneity. In the rural agrarian settings, landlords, self-cultivators and tenants shared a similar living pattern and value system based on the agricultural cycle. The urban area, however, exhibited a variety of work patterns of local functionaries, artisans and merchants. Many middle- and low-status people might well have found the high-status culture of the rural area incompatible with their own. 相似文献

This paper is based on the premise that corrupt uses of public, civic networks ostensibly built and legitimated for their altruistic purposes can be a source of network subversion and corruption. Open, public, civic networks of South Korea seem to be systemic and organizational facilitators of criminality instead of assumptions of criminality being related only to closed, criminal cultures or anomie. We test whether increasing participation in the major social networks of Korean civic life – networks based on geography (common ancestral hometown), family (extended kinship), and education (alumni) – are associated with increasing penchants for self-admitted criminal collusion, in this case, bribery. We argue that due to relational association or within-network favoritism the increase in multiple networks per individual generates increasing social capital of access, information, and trust which may be subverted toward some form of private criminal collusion. 相似文献
