This article sketches a historical‐structural picture of Franco‐American relations from a French point of view. The historical approach is chosen because it allows understanding of how mutual visions and images develop. Franco‐American mutual images are traced from the time of French involvement in the birth of the US, through the period when France and the US were the first two grand republics with universalist claims. The difficult relationship between these two states with remarkably similar universalist self‐images is seen against a background of a rising US and declining France, with the fall of France in 1940 seen as a turning point. The Gaullist project of removing this humiliation marks the Franco‐American relationship, as compared with that of Britain (declined but undefeated), and a Germany reborn within the Euro‐Atlantic institutions after the cataclysm of 1945. 相似文献

Following a CBRN incident, first responders use decontamination procedures to reduce the risk of exposure. The effect of decontamination on forensic trace material has, however, not been fully examined. This study sought to evaluate the effect of five different physical or chemical decontamination materials on the recovery of latent fingerprints. Fingerprints were deposited on glass slides, decontaminated, and assessed on the presence of ridge detail. The results demonstrate that decontamination affects the quality of latent fingerprints substantially. On at least 61% of the fingerprints, a reduced amount of ridge detail was observed upon decontamination. Furthermore, development with cyanoacrylate appeared not to succeed anymore. Instead, the ability of vacuum metal deposition to successfully develop decontaminated fingerprints is demonstrated. The results from this study may contribute to an increased forensic awareness regarding decontamination and emphasize the necessity for further research into new item decontamination procedures or new forensic initiatives prior to decontamination. 相似文献

Objectives
Test the hypothesis that dispositional self-control and morality relate to criminal decision making via different mental processing modes, a ‘hot’ affective mode and a ‘cool’ cognitive one.Methods
Structural equation modeling in two studies under separate samples of undergraduate students using scenarios describing two different types of crime, illegal downloading and insurance fraud. Both self-control and morality are operationalized through the HEXACO model of personality (Lee and Ashton in Multivariate Behav Res 39(2):329–358, 2004).Results
In Study 1, negative state affect, i.e., feelings of fear and worry evoked by a criminal prospect, and perceived risk of sanction were found to mediate the relations between both dispositions and criminal choice. In Study 2, processing mode was manipulated by having participants rely on either their thinking or on their feelings prior to deciding on whether or not to make a criminal choice. Activating a cognitive mode strengthened the relation between perceived risk and criminal choice, whereas activating an affective mode strengthened the relation between negative affect and criminal choice.Conclusion
In conjunction, these results extend research that links stable individual dispositions to proximal states that operate in the moment of decision making. The results also add to dispositional perspectives of crime by using a structure of personality that incorporates both self-control and morality. Contributions to the proximal, state, perspectives reside in the use of a new hot/cool perspective of criminal decision making that extends rational choice frameworks. 相似文献885.
Testing for Individual Factors for the Fear of Crime Using a Multiple Indicator-Multiple Cause Model 总被引:1,自引:0,他引:1

In the extant literature, very few studies have simultaneously examined the impact of individual attributes, neighbourhood disorder and social cohesion on an individual’s fear of crime. This article addresses the use of multiple-indicator, multiple-cause (MIMIC) analysis for testing different variables related to the fear of crime based on a number of theories. Face-to-face interviews with residents of a high-crime council estate were conducted to examine the crime rate, disorder, cohesion and the fear of crime in the participants’ residential area. The results support the incivilities thesis and the vulnerability hypothesis, while the social disorganisation theory was partially supported. It was concluded that women and the elderly demonstrate higher levels of fear than men and the nonelderly and that crime, disorder and social cohesion have a direct effect on one’s level of fear, as the decreases in neighbourhood cohesion increase the individuals’ levels of fear. In addition, people who have been victimised and those who perceive higher levels of incivility were found to be more fearful of crime. By incorporating the three theories, the final model is able to account for 50 % of the variance in the fear of crime. 相似文献

Neither absolute THC content nor morphology allows the unequivocal discrimination of fiber cultivars and drug strains of Cannabis sativa L. unequivocally. However, the CBD/THC ratio remains constant throughout the plant's life cycle, is independent of environmental factors, and considered to be controlled by a single locus (B) with two codominant alleles (BT and BD). The homozygous BT/BT genotype underlies the THC‐predominant phenotype, BD/BD is CBD predominant, and an intermediate phenotype is induced by the heterozygous state (BT/BD). Using PCR‐based markers in two segregating populations, we proved that the THCA synthase gene represents the postulated B locus and that specific sequence polymorphisms are absolutely linked either to the THC‐predominant or the THC‐intermediate chemotype. The absolute linkage provides an excellent reliability of the marker signal in forensic casework. For validation, the species‐specific marker system was applied to a large number of casework samples and fiber hemp cultivars. 相似文献

Being at the frontline of climate change, small island developing states (SIDS) hold a serious stake in climate negotiations. However, these countries usually are marginalized in the international political arena, due to their lack of structural power. This paper explores the strategic influence of SIDS and its representative organization, the Alliance of Small Island States, in the negotiations leading to the Copenhagen summit of December 2009. Using the concepts of leadership and discourses, the position, strategies, and impact of SIDS are analyzed on negotiation processes and their final outcome, focusing on three core demands of small island countries at Copenhagen: a temperature rise limit of 1.5 °C above preindustrial levels, funding for adaptation, and a legally binding outcome. Results reveal that SIDS practiced entrepreneurial, intellectual, and environmental leadership strategies and especially made use of moral claims in the debate. Given their near absence of structural power, they managed to secure a surprisingly large part of “their” agenda and interests in the final Copenhagen Accord, especially through (discourse) coalitions with various other state and non-state stakeholders. 相似文献

While the popularity of using the item count technique (ICT) or list experiment to obtain estimates of attitudes and behaviors subject to social desirability bias has increased in recent years among political scientists, many of the empirical properties of the technique remain untested. In this paper, we explore whether estimates are biased due to the different list lengths provided to control and treatment groups rather than due to the substance of the treatment items. By using face-to-face survey data from national probability samples of households in Uruguay and Honduras, we assess how effective the ICT is in the context of face-to-face surveys—where social desirability bias should be strongest—and in developing contexts—where literacy rates raise questions about the capability of respondents to engage in cognitively taxing process required by ICT. We find little evidence that the ICT overestimates the incidence of behaviors and instead find that the ICT provides extremely conservative estimates of high incidence behaviors. Thus, the ICT may be more useful for detecting low prevalence attitudes and behaviors and may overstate social desirability bias when the technique is used for higher frequency socially desirable attitudes and behaviors. However, we do not find strong evidence of variance in deflationary effects across common demographic subgroups, suggesting that multivariate estimates using the ICT may not be biased. 相似文献

In contemporary times, a fundamental aspect for organization has been to achieve innovation through culture and approach to encourage the search and development of new ideas, new products, and new services; this is a key point to fulfill the competitive advantages which a company needs to be successful in the global market. The Sinaloa horticultural company has more than 100 years' history in the United States export market, and is presenting new challenges and demands from the market in order for it to achieve its permanence. The objective of this research is to identify and propose different strategies to implement management innovation, which in its essence is the one that coordinates, directs, and controls the human resource considering culture as an integral part, with a capacity to generate the spark and function as a motivating source which drives companies to consolidate and integrate supply chains. 相似文献
