The international harmonization of technology‐related regulations seeks certain norms across diverse contexts. Harmonization efforts are based primarily on the promulgation of state‐centered command and control forms of regulation, though they may also be accompanied by the diffusion of more plural approaches that are decentered from the state. We contrast the ways in which the “proper” use of transgenic cotton seed technologies is understood in harmonizing regulations with the way this technology is used in practice in regions of Argentina and China. We find divergence that poses challenges for both state‐centered and decentered approaches to harmonization. While state‐centered approaches are blind to some critical processes on the ground, decentered strategies are found wanting in situations where norms remain deeply contested amongst actors situated in very uneven power relations. In both cases, we find that establishing and securing norms that are socially just and environmentally sustainable means attending much more explicitly to the political economies in which technological practices actually take root.  相似文献

The stability of drugs in biological specimens is a major concern during the evaluation of the toxicological results. The stability of morphine, codeine, and 6‐acetyl‐morphine in blood was studied after different sampling conditions: (i) in glass, polypropylene or polystyrene tubes, (ii) with addition of dipotassium ethylene diamine tetraacetic acid (K2EDTA) or sodium oxalate (Na2C2O4), and (iii) with or without the addition of sodium fluoride (NaF). Spiked blood samples were stored at two different temperatures (4 and ?20°C), analyzed after different storage times and after three freeze–thaw cycles. Opiate concentrations were decreased in all conditions, but the most unstable was 6‐acetyl‐morphine. The addition of NaF as preservative improved the stability of opiates at all conditions studied, whereas the type of anticoagulant did not affect the stability of opiates. It was concluded that blood samples should be stored at ?20°C in glass tubes containing oxalate and NaF for maximum stability.  相似文献

This paper examines gang joining among juveniles in socially disadvantaged residential neighbourhoods with gang presence. The analysis is based on a school-based survey among students (n = 1,886) in Copenhagen, the capital of Denmark. The theoretical framework is inspired by the Eurogang Program of Research—that is, their definition of street gangs was utilized in the study. The results indicate that 13% of the youths aged 13–17 are members of street gangs. The street gang members are more likely to be characterized by poor parental monitoring, weak pro-social values, and high-risk lifestyles compared with other crime involvement groups, including serious offenders; and they commit a disproportionately large number of offences. The results also indicate that proximity to criminal gangs on a higher organizational level than street gangs increases willingness to join such criminal gangs, especially for street gang members, as they are more likely to be in contact with older and more powerful gang members already—for example, they have helped them by being a look-out or passing messages.  相似文献

Abstract: Here, we present a case of an unidentified male whose remains, except for the right arm, were recovered from the Gulf of Mexico 10 years prior to osteological analysis by forensic anthropologists. After the poorly preserved soft tissue was removed and the bones cleaned, forensic analysis revealed an unusual series of hard tissue trauma later attributed by a shark expert as shark scavenging and/or predation. Identified were five unique hard tissue trauma patterns that are bite mark artifacts produced by sharks: punctures without fractures, punctures with associated fractures, striations with bone shaving, overlapping striations, and incised bone gouges. The cooperation among experts provided a comprehensive death case analysis and a better understanding of shark‐inflicted trauma on human skeletal remains.  相似文献

Around 1900, various crimes were still caused by criminal superstition. Criminologists like Hans Gross, Albert Hellwig and August L?wenstimm were engaged in the exploration of this topic aiming at the complete explanation of criminal behaviour linked to superstition. Crimes against pregnant women and infants are particularly good examples to illustrate the problems arising from crimes motivated by superstition. When assessing superstition under scientific and legal aspects, the criminologists applied different approaches, although positivistic rationalization was the most common tendency. In the forensic and legal evaluation of crimes related to superstition the problematical questions were whether the perpetrator was criminally responsible and how the offence was to be legally qualified. In many cases, criminals motivated by superstition were treated with more lenience.  相似文献

This article describes the autopsy findings of a victim of a shark attack that took place off the coast of Pernambuco, Brazil. The victim was rescued and immediately taken to a nearby hospital but did not survive, even though the lapse of time between the attack and verification of death did not exceed 15 minutes. The presence of a single, large, contused and incised, semiarched wound with a serrated aspect was decisive in elucidating the event. Thus, this study discusses aspects related to the aggressor species, to the autopsy, to the type of wound, and to the causes that have led to a significant increase in this type of event in the area. It was concluded that the lesion was produced while the victim was still alive and that it was the cause of death.  相似文献

Teeth are recently drawing attention for their potential as biological modeling investigation samples due to their ability to be collected and their slow substance metabolism. There is no active metabolism of elements after the completion of dentin. Dentin is surrounded by enamel and cementum, and is not affected by the oral environment. Therefore, the amount of trace elements in dentin may change with age, and this is considered to be a reliable biological load index. The objectives in this study are to demonstrate concentrations of elements in the dentin of healthy Japanese subjects by sex and age, and to reveal the relationship between element levels and age. 121 healthy teeth samples were extracted due to periodontal disease or orthodontic treatment. Each tooth was sliced from the crown to the root apex into 0.5-1mm thickness, then enamel, cementum, and the pulp were removed; the dentins were used as samples. The concentration of 10 trace elements (B, Mn, Co, Cu, Zn, Rb, Sr, Mo, Cd, and Pb) in the dentin was measured using inductively coupled plasma mass spectrometer (ICP-MS). The differences Co and Pb in the dentin between men and women were significant (p<0.01). Significant positive correlation was observed between B, Co, Cu, Zn, Sr and Pb concentrations in the dentin and age (p<0.001). The results of the present study suggest that human dentin is an appropriate substance for relativity with sex and age at further future research.  相似文献

Although there has been an increase in research on sex offenders' modus operandi, geographic decision making, and hunting behavior, most studies still tend to emphasize criminal motivation while overlooking the role of situational and environmental factors. Studies of mixed samples of rapists and child molesters typically neglect to conduct comparative analyses. Consequently, the full nature of their distinction is not clear. This is particularly problematic for the understanding of crossover or polymorphous sex offenders, who target victims from various age groups. Using a sample of 216 incarcerated sexual offenders, hunting behavior patterns were identified and tested to establish which hunting behavior patterns were associated with each type of offender. Relationships between modus operandi, geographic decision making, and hunting behavior were also examined. Three types of offender were identified: (a) manipulative; (b) opportunist; and (c) coercive. The manipulative offender is typically a child molester. The coercive offender is typically a rapist. The opportunist offender includes both rapists and child molesters. These findings emphasize the relevance of polymorphous, crossover, or versatile sex offenders and suggest new ways of conceptualizing sex offenders and their study.  相似文献

Whistleblowers, employees of conscience who report on wrongdoing, integrate into their socially useful role one of exposing institutional torpor and bureaucratic incompetence in those official structures responsible for the investigation and correction of wrongdoing. This paper reports on the finding from Australia's largest study into whistleblowers. It shows a crisis of competence in the official capacity of government structures to respond effectively to disclosures made in the public interest.  相似文献
