Following the terrorist attacks of September 11, 2001, U.S. president George W. Bush articulated a new national security strategy based on striking terrorist organizations and the states that harbor them before they could endanger the United States. Though expressed in the language of preemption, the Bush strategy embodied a far more problematic doctrine of preventive warfare. Whereas the grounds for preemption lie in evidence of a credible, imminent threat, the basis for prevention rests on the suspicion of an incipient, contingent threat. We argue that an American national security strategy that embraces preventive war will set an inauspicious precedent, undermining normative restraints on when and how states may use military force.  相似文献

Abstract:  It is generally accepted that nuclei degrade in developing hair shafts but the point at which such occurs has not been investigated. The fate of mitochondria in the keratinizing hair shaft has been less clear. This study uses transmission electron microscopy to investigate when nuclei and mitochondria are no longer visible in the developing hair shaft. Serial sections were obtained from anagen head hairs absent follicles in order to determine the sequence of degradation of nuclei and mitochondria in the hair shaft by starting at the root bulb and proceeding toward the hair tip. It was demonstrated that nuclei and mitochondria become invisible in the keratinizing hair shaft at about the same time. This was found to occur fairly early in the process at the level of the hair shaft where the hair cuticle becomes permanent.  相似文献

Data Safety and Monitoring Boards (DSMBs) have been referred to as a "growth industry," and this trend continues to be fueled by recent FDA guidance and the NIH's requirement that DSMBs be employed in virtually all phase III clinical trials. The widening role of DSMBs has been sporadically questioned on ethical grounds, but growth has continued, despite the fact that many of the questions endure, unanswered, save for repeated references to safeguarding the scientific integrity of trials. This may be about to change. The recently appointed director of the Office for Human Research Protections (OHRP), Jerry Menikoff, is on record as regarding current practices — where consent forms often promise what the DSMB has been assembled to specifically not provide — as constituting fraudulent behavior. That is, a subject may inherently rely on, to their detriment, information that has been misrepresented in the consent document. In this paper, we assemble some of the enduring questions and top them off with Menikoff's tour de force to present what we hope will be a compelling argument to require that consent forms fairly represent what the DSMB will do — and not do — with trial data as they accumulate. We argue that DSMBs should be used only in rare circumstances, and question the practice of precluding principal investigators from DSMB membership, but our main thrust is to ensure that DSMBs, when used at all, are properly described in trial consent forms.  相似文献

Purpose. There were three objectives of this study: (1) To assess the possibility of using pupil diameter as an index of deception in the context of a comparison question polygraph test. (2) To determine if pupil diameter would make a significant contribution to an optimal multivariate classification equation in combination with the traditional predictor variables used in field polygraph practice. (3) We explored the possibility of replacing one or more of the traditional predictor variables with pupil diameter. Methods. We used a laboratory mock crime experiment with 24 participants, half of whom stole $20 (US) from a secretary's purse. Participants were tested with a comparison question test modelled after standard field practice. Physiological measures were taken with laboratory quality instrumentation. Features were extracted from the physiological measures. Those features were subjected to a number of different statistical analyses. Results. Innocent participants showed larger increases in pupil diameter in response to probable‐lie questions than to relevant questions. Guilty participants did not show differential responding to the question types. The additional of pupil diameter to a multivariate classification model approached, but did not reach significance. Subsequent analyses suggest that pupil diameter might be used to replace the traditional relative blood pressure measure. Conclusions. Pupil diameter was found to be a significant predictor variable for deception. Pupil diameter may be a possible replacement for the traditional relative blood pressure measure. Additional research to explore that possibility would seem to be warranted.  相似文献

This article explains, first, why Australia’s government under John Howard, together with the United States Bush administration initiated the Asia Pacific Partnership on Clean Development and Climate (APP) and, second, why the succeeding Rudd government continued to support this initiative. Climate policy under the conservative Howard government (1995–2007) in Australia was largely dictated by fossil fuel and mineral sector interests, and reflected a close alliance with the Bush administration. The Howard government shunned the Kyoto Protocol, refused to set national binding greenhouse gas reduction targets and preferred voluntary cooperative measures with industry. The APP was part of the Howard government’s strategy to demonstrate some policy movement on climate change while postponing serious action. Climate change was a key issue in the election of the Rudd Labor government in Australia in December 2007. The Rudd government quickly ratified Kyoto, adopted emission reduction targets, and moved to introduce emissions trading. The Rudd government’s decision to continue involvement with the APP, albeit with diminished funding, was a pragmatic one. The APP was supported by industry and provided bridges to China and India—both key countries in the post-2012 UNFCCC negotiations. Finally, in order to assess the long-term outlook of the APP, the article provides a preliminary assessment as to whether the APP advances technology transfer.

Employment status following spinal cord injury (SCI) has important implications for financial and psychosocial well-being. Several age-related variables-in particular chronological age, duration of SCI, and age at SCI onset-have been identified as being associated with employment among individuals with SCI. Cross-sectional investigations of this topic are complicated by methodological and statistical issues associated with aging and disability. The purpose of the current study was to examine the associations between three aging variables and employment status in individuals with SCI through a series of regression analyses. Six hundred twenty individuals with SCI completed a survey that included measures of demographic characteristics, pain, psychological functioning, physical functioning, fatigue, and sleep. The results indicated that chronological age and age at SCI onset were significant predictors of employment status. A significantly greater proportion of individuals aged 45-54 were employed compared to those aged 55-64 even after controlling for biopsychosocial variables. Additionally, there was a negative linear relationship between percent employed and age at SCI onset, and this relationship was not accounted for by the biopsychosocial variables. The analyses used in this study provide one method by which to disentangle the effects of different age-related variables on important SCI outcomes in cross-sectional research. Continued research in this area is needed to better understand age-related effects on employment status, which could be used to help maximize the quality of life in individuals with SCI.  相似文献

It was hypothesized that male perpetrators of domestic violence in the early stages of a 1-year process of cognitive restructuring therapy would manifest on the Rosenzweig Picture-Frustration Study higher levels of extra-aggressiveness than in later stages of the therapy process. A sample of male batterers in the process of treatment took the Rosenzweig instrument. The resulting responses were rated by trained scorers. Chi-square calculations revealed that batterers in the first quarter of treatment manifested Rosenzweig responses indicative of extra-aggressiveness, whereas in the fourth quarter, batterers manifested Rosenzweig responses indicative of im-aggression. The data are discussed relative to implications for domestic violence treatment and the use of the Rosenzweig instrument as an index of treatment progress.  相似文献

Using a classification of homicides based on the victim-offender relationship, this research analyzes individual-level data from a local prosecutor's office in Taiwan with multinomial logistic regression to locate the more precise correlates of three different homicide relationship types. The results of the analyses provide further support for the hypothesis that such partitioning of homicides is fruitful in revealing the relationships otherwise obscured. They indicate that both sociodemographic variables and situational variables are important correlates of three different homicide relationships, but their strengths vary based on the particular homicide relationship type. Age and crime premises correlate with homicide differently based on the victim-offender relationship. Premeditation is related to acquaintance homicide but not to intimate homicide. In contrast, previous conviction is associated with intimate homicide but not with acquaintance homicide. The implication of the findings is discussed within the limitation of the data.  相似文献

Within the framework of the ENFSI Expert Working Group "Firearms" a proficiency test on the detection and identification of GSR by energy-dispersive scanning electron microanalysis (SEM/EDX) is carried out in a 2 years term. The latest test was performed in 2005/2006 and was denoted as GSR2005. Seventy-five laboratories from 28 countries participated in this proficiency test and submitted in total 83 independent data-sets. The participating laboratories were requested to determine the total number of PbSbBa containing particles on a synthetic test sample following their own laboratory specific methods of automated GSR particle search and detection by SEM/EDX. Furthermore size and position of the detected particles had to be reported by the laboratories and were evaluated statistically. The results were compiled by means of z-scores according to the IUPAC and EURACHEM guidelines-assessing individual laboratory achievements (inter-laboratory) as well as intra-laboratory performance-and were compared to the results of the previous proficiency test run GSR2003 (1). The comparison shows that there is a noticeable improvement in the method's detection capability.  相似文献
