ABSTRACTThe local business elites of El Salvador were generally in favour of the peace agreement and supported its negotiation and implementation in 1992, while in Guatemala the private sector reluctantly supported the peace process and, after the peace agreements were signed in 1996, the private sector sought to obstruct parts of its implementation. In the aftermath of the peace accords, business elites united around an ideology espousing a minimal state and a focus on market solutions to social problems. Although welcoming the security-related measures in the peace accords, business elites have often obstructed transformations towards more inclusive and democratic societies. However, in recent years there has been a change in discourse among influential business associations towards recognition of the need for strong state institutions and the need for institutionalised mechanisms for dialogue to find solutions to social problems. In this article, we seek to shed light on the significance of this discursive turn for continued peace-building. 相似文献

This study is one of the very few, and the most extensive to date, which has examined deceptive behavior in a real-life, high-stakes setting. The behavior of 16 suspects in their police interviews has been analyzed. Clips of video footage have been selected where other sources (reliable witness statements and forensic evidence) provide evidence that the suspect lied or told the truth. Truthful and deceptive behaviors were compared. The suspects blinked less frequently and made longer pauses during deceptive clips than during truthful clips. Eye contact was maintained equally for deceptive and truthful clips. These findings negate the popular belief amongst both laypersons and professional lie detectors (such as the police) that liars behave nervously by fidgeting and avoiding eye contact. However, large individual differences were present. 相似文献

In the current climate of increasing violence against the police, the use of force by police officers has been the focus of
much dabate, ranging from the use of non lethal incapacitant sprays to the use of lethal forceI. We review literature concerning the use of lethal force by police officers, evaluate its utility for operational contexts,
consider its implications for training and propose that new technological devices can revolutionise the identification of
crucial variables. 相似文献

This study examines whether or not using a person as a standard/comparison improves the ability of a child witness to provide
more accurate detail about a previously observed person. Study participants included 135 children who observed a male stranger
and were then later asked to describe and answer various questions about that person using a third-person standard/comparison.
Despite the fact that one-half of participants were exposed to a standard/comparison, neither participants’ gender or exposure
to the standard/comparison improved recollection outcomes. However, the gender of the standard/comparisons - especially where
female - did have a significant effect on the recall ability of male participants. 相似文献

A series of experiments were conducted using various types of pollen grain, powder and metal particulates to determine their persistence on a range of different types of materials. The decay curves generated in the repeated experiments all broadly conform to those obtained and already presented in the literature for fibres and glass particulates. The experiments presented in this paper were conducted for up to 647 hours for individual runs and it was found that a general rule existed that it was the material type rather than the particulate type that was the major controlling factor in the persistence of particles. For the pollen grain experiments the overall theory is sustained; there is a significant loss initially followed by a slower decay although this is not precise given the varied nature of palynomorph types. The manner by which the particulates were introduced onto the material had an initial immediate effect, however, the persistence of these particulates over longer periods of time was generally unaffected. 相似文献

The routine production of a cast of a shoe-print taken in soil provides information other than shoe size and gait. Material adhering to the surface of the cast represents the preservation of the moment of footprint impression. The analysis of the interface between the cast and soil is therefore a potentially lucrative source of information for forensic reconstruction. These principles are demonstrated with reference to a murder case which took place in the English Midlands. The cast of a footprint provided evidence of a two-way transfer of material between the sole of a boot and the soil of a recently ploughed field. Lumps of soil, which had dried on a boot, were deposited on the field as the footprints were made. Pollen analysis of these lumps of soil indicated that the perpetrator of the imprint had been standing recently in a nearby stream. Fibre analysis together with physical and chemical characteristics of the soil suggested a provenance for contamination of this mud prior to deposition of the footprint. Carbon/nitrogen ratios of the water taken from the cast showed that distilled water had been used thus excluding the possibility of contamination of the boot-soil interface. It was possible to reconstruct three phases of previous activity of the wearer of the boot prior to leaving the footprint in the field after the murder had taken place. This analysis shows the power of integrating different independent techniques in the analysis of hitherto unrecognised forensic materials. 相似文献

Quartz sand surface texture analysis has been automated for the first time for forensic application. The derived Basic Image Features (BIFs) provide computer-generated texture recognition from preexisting data sets. The technique was applied to two distinct classification problems; first, the ability of the system to discriminate between (quartz) sand grains with upturned plate features (indicative of eolian, global sand sea environments) and grains that do not exhibit these features. A success rate of grain classification of 98.8% was achieved. Second, to test the ability of the computer recognition system to identify specific energy levels of formation of the upturned plate surface texture features. Such recognition ability has to date been beyond manual geological interpretation. The discrimination performance was enhanced to an exact classification success rate of 81%. The enhanced potential for routine forensic investigation of the provenance of common quartz sand is indicated. 相似文献
