Utilized coefficient of friction during walking: static estimates exceed measured values

This study compared utilized coefficient of friction (COF) measured during nonslip pedestrian gait to estimated utilized COF values calculated using anthropometric (i.e., leg length) and stride characteristic data (i.e., impact angle, step length). Twenty healthy adults walked at slow, medium, and fast speeds with kinematic and kinetic data recorded simultaneously. Estimated and measured impact angle varied with walking speed, with greater angles evident with faster speeds (p < 0.001 and p < 0.05, respectively). The estimated impact angle was greater than the measured impact angle (p < 0.05). Estimated and measured peak utilized COF values varied with walking speed, with higher utilized COF values evident with faster speeds (p < 0.001 and p = 0.001, respectively). Estimated utilized COF values were 86, 118, and 131% greater than measured peak utilized COF values for slow, medium, and fast speeds, respectively (p < 0.001). Higher estimated utilized COF values varied moderately with increased measured peak utilized COF values (r = 0.522; p < 0.001). These data suggest that impact angle and step length alone cannot be used to accurately assess the utilized COF on level walking surfaces.     

Community service: its use in criminal justice

Community service has been perceived as a desirable alternative to the use of short-term imprisonment as a response to increasing crime rates. Although heavily used in Western Europe and the Old Commonwealth, its adoption in the United States has been localized and patchy. Use in Asia, South America, and Africa is limited. This article reviews the use of community service in selected countries around the world. It concludes that community service can be used as a pretrial diversion, as a condition of probation or parole, or as an option to work off a fine by an impoverished offender. Very often, it is itself a stand-alone sentence, but it can also be used in addition to other sentences. Some countries give community service a secure place in the sentencing tariff, whether as retributively oriented "hard end" penalties or as rehabilitative and/or restorative endeavors. Others leave usage, within broad qualification criteria, to the discretion of sentencers.     

The evolution of a campaign: tracking press coverage and party press releases through the 2001 UK General Election

• This paper builds upon a content analysis of all news articles that appeared in six national daily newspapers and of all national press releases issued by the three main political parties during the UK General Election 2001 campaign. The results were compared with data from two opinion polls conducted at the start and at the end of the campaign. Here, using the same basic data, we track the coverage of issues in party press releases and daily newspapers on a weekly basis to determine how the parties' priorities and press coverage evolved.
• The results show that the Labour and Liberal Democrat campaign strategies, in terms of relative issue priorities, did not change during the campaign. However, the Conservatives shifted their attention to the public priorities of Health and Education towards the end of the campaign. There is evidence that the Conservative emphasis on Europe and taxation earlier in the campaign may have influenced the volume of press coverage but did not appear to have affected relative party standings. The implications of these results for political marketers are considered.

Organized crime in Ukraine: Challenge and response

Organized crime in Ukraine has helped to derail the transition to a democratic polity and a free market economy, has generated considerable violence and corruption, and has contributed significantly to the development of a climate that does little to encourage foreign direct investment. Consequently this article explains why Ukraine, along with other states of the Former Soviet Union, developed a major organized crime problem during the 1990s. Having done this, it delineates some of the major contours of organized crime in Ukraine, identifying the major participants in organized crime, the variations in the phenomenon in different cities and regions, and the major activities of organized crime. The article also examines the kinds of initiatives that have been taken by the government of Ukraine in its efforts to combat organized crime, before suggesting some areas in which these efforts could be significantly improved.     

Postmortem magnetic resonance images of the injured brain: effective evidence in the courtroom.

Magnetic resonance images (MRI) of the whole, formalin-fixed brain produce details of pathologic changes deep within brain substance not apparent on external examination. Photographs of these radiographic images present pathologic features in a black-and-white, 2-dimensional format which has proven particularly effective in court before judge and jury. This pathologist has noted acceptance of such photographs in explaining to jurors the details of his testimony in selected cases where brain trauma resulted in a wrongful death. Penetrating missile wounds and blunt impact injuries are particularly well documented by this method.
