Deliberative democracy can be defined as a political system based on citizens' free discussion of public issues. While most scholars have discussed deliberative democracy normatively, this study attempts to test the validity of a model of deliberative democracy through examining the interrelationships among its four components: newsmedia use, political conversation, opinion formation, and political participation. Sufficient empirical evidence was found to support the hypotheses that (a) news-media use is closely associated with the frequency of political conversation in daily life both at general and issue-specific levels; (b) willingness to argue with those who have different opinions is influenced by majority perceptions and by news-media use and political talk; (c) news-media use and political conversation have positive effects on certain measures of the quality of opinions (argument quality, consideredness, and opinionation) and perhaps on opinion consistency; and (d) news-media use and political conversation are closely associated also with participatory activities, but more so with "campaigning" than "complaining."  相似文献

Abstract: Often carrion decomposition studies are conducted using a single carcass or a few carcasses sampled repeatedly through time to reveal trends in succession community composition. Measurements of biomass and other abiotic parameters (e.g., temperature) are often collected on the same carcasses but are rarely a focal point of the studies. This study investigated the effects that repeated sampling during experiments have on the decomposition of carrion, measured as both gross biomass (carcass plus fauna) and net biomass (carcass only), on carcasses disturbed on every visit (with weighing only or also with the collection of fauna) and on carcasses disturbed only once. Each trial lasted at least 21 days, with samples taken in triplicate. Rat carcasses used in this study were placed in the field on the same day and either weighed on every visit or ignored until a given day. Internal and ambient air temperatures were recorded on each carcass at the time of sampling and on undisturbed carcasses using temperature loggers. The presence of succession fauna did not result in significant biomass loss on most days; however, there were individual days early in decomposition (days 3 through 6) when the succession fauna comprised a large portion of the gross biomass. With the exception of biomass loss by the emigration of maggots on days 4 and 5, neither repeated weighing of the carcasses nor repeated weighing and faunal sampling of the carcasses statistically affected the rate of biomass loss. Internal temperatures of carcasses sampled repeatedly were frequently 2–5°C lower than those that had not been disturbed, and ambient temperatures differed significantly depending on the location of measurement device. Results indicate that methods used historically for biomass loss determination in experimental forensic entomology studies are adequate, but further refinements to experimental methodology are desirable.  相似文献

Assault using a knife is a common problem in the United Kingdom. Between February 1992 and December 1996, 120 individuals died or received hospital treatment in Edinburgh after being assaulted with a knife. Twenty individuals (17%) died as a result of their injuries. Comparison of the survivors with non-survivors revealed both groups to have similar age and sex distributions, but those who died had significantly more severe injuries when scored according to the Abbreviated Injury Scale. Eight individuals died of unsurvivable chest injuries at the scene of the attack and of the remainder, only five reached hospital with signs of life. Analysis of hospital treatment using TRISS methodology revealed there to be two unexpected survivors and no unexpected deaths. The risk of death appears to depend mostly upon injuries sustained and also to a lesser extent upon other factors such as alcohol consumption and the presence of a bystander capable and willing to request emergency medical assistance. There does not appear to be much potential to save lives by improving hospital treatment for those assaulted with a knife in Edinburgh. Instead, greater focus needs to be placed upon rapid transfer to hospital and upon restricting the possession and use of knives.  相似文献

The concentrations of lead (Pb), barium (Ba), and antimony (Sb), characteristic of GSR, were determined in soil sediments and immature (larvae) of cadaveric flies of the family Calliphoridae, by inductively coupled plasma mass spectrometry (ICP-MS). This research refers to a case study from two real crime scenes in which the corpses were in an advanced state of decomposition. In case 1, the victim had holes similar to gunshot wounds, and in case 2, there was no evidence of perforations in the corpse. Soil sediment collection was performed at three different points of the terrain, at a minimum distance of 10 m from the corpse, for cases 1 and 2. In relation to the collection of immatures, larvae were collected in regions of the mouth, nose, and orifices similar to the entry of firearms projectile into the body, for case 1, and collection of larvae and pupae, located on the body and underneath it, for case 2. It was possible to detect and quantify the three elements of interest (Pb, Ba, and Sb) by ICP-MS in both sediment and cadaveric larvae. Concentrations of 4.44, 8.74, and 0.08 μg/g were obtained for Pb, Ba, and Sb, respectively, in the soil for case 1. For the case 2, the concentrations in Pb, Ba, and Sb were from 16.34 to 26.02 μg/g; from 32.64 to 57.97 μg/g and from 0.042 to 0.30 μg/g, respectively. In the larvae, Pb, Ba, and Sb were quantified in cases 1 and 2 with a concentration of 6.28 and 1.78 μg/g for Pb, 1.49 and 2.94 μg/g for Ba, 0.50 μg/g and <LD for Sb, respectively. These new results present the detection of characteristic elements of GSR in cadaveric larvae in humans in a real crime scene, besides highlighting the importance of the study of immature flies, using the ICP-MS technique in forensic analysis.  相似文献

In the imaginations of many, war in British India had its focus on the North-West Frontier and was fought against the tribes of that region. However, British thinking about Indian defence involving Afghanistan underwent tremendous change over the period under consideration. British plans to meet a Russian invasion on the Kabul-Kandahar Line in 1904 resembled those of any other Nineteenth Century Imperial campaign, with numbers of infantry and cavalry still being thought of and referred to as bayonets and sabres. Twenty years later, heavily influenced by the experiences of the Great War in the region and the Third Afghan War and associated operations, the calculus was different with logistics changed by motor vehicles and the introduction of what today are referred to as force multipliers, such as aeroplanes and machine guns. It was over this period that warfare as fought and conceptualised by men like Napoleon gave way to modern practices familiar to us today.  相似文献

Wildlife trafficking, along with other green crimes, receives little attention from the criminological community. This study provides further knowledge of this black market, and exposes the structural harms that are associated with it, by examining the illegal trade in falcons in Russian Far East. The structural harms proposed here are that wildlife trafficking, and the illegal raptor trade in particular endangers the environment, is cruel to animals, and threatens national and human security because of its connection to other dangerous illicit activities. Through semi‐structured interviews, trade statistics, and online news sources, a framework is developed as to who is involved, how it is occurring, and where it is taking place as well as possible ways in which to curb this activity.  相似文献
