A comparison of penetration and damage caused by different types of arrowheads on loose and tight fit clothing

Bows and arrows are used more for recreation, sport and hunting in the Western world and tend not to be as popular a weapon as firearms or knives. Yet there are still injuries and fatalities caused by these low-velocity weapons due to their availability to the public and that a licence is not required to own them. This study aimed to highlight the penetration capabilities of aluminium arrows into soft tissue and bones in the presence of clothing. Further from that, how the type and fit of clothing as well as arrowhead type contribute to penetration capacity. In this study ballistic gelatine blocks (non-clothed and loose fit or tight fit clothed) were shot using a 24 lb weight draw recurve bow and aluminium arrows accompanied by four different arrowheads (bullet, judo, blunt and broadhead).The penetration capability of aluminium arrows was examined, and the depth of penetration was found to be dependent on the type of arrowhead used as well as by the type and fit or lack thereof of the clothing covering the block. Loose fit clothing reduced penetration with half of the samples, reducing penetration capacity by percentages between 0% and 98.33%, at a range of 10 m. While the remaining half of the samples covered with tight clothing led to reductions in penetration of between 14.06% and 94.12%.The damage to the clothing and the gelatine (puncturing, cutting and tearing) was affected by the shape of the arrowhead, with the least damaged caused by the blunt arrowheads and the most by the broadhead arrows. Clothing fibres were also at times found within the projectile tract within the gelatine showing potential for subsequent infection of an individual with an arrow wound.Ribs, femur bones and spinal columns encased in some of the gelatine blocks all showed varying levels of damage, with the most and obvious damage being exhibited by the ribs and spinal column.The information gleaned from the damage to clothing, gelatine blocks and bones could potentially be useful for forensic investigators, for example, when a body has been discovered with no weapons or gunshot residue present.     

Peace and Conflict: Alternative Strategies of Governance and Conflict Resolution

This article examines the present discourse of conflict resolution and offers an alternative framework for analyzing the generic sources of conflict at the community, state, and interstate levels. In particular, we argue that although peace is a universal value, there are no universally best strategies to achieve it. This, however, does not mean that the path to peace is fundamentally different in every context. We claim that stable democratic political structures in general lead to peace both in the international and the domestic realms. As such, democratization does lead to peace, but the paths to stable democracy are context sensitive. Therefore, the success of efforts aimed at creating long-term peace, both among and within nations, depends on the extent to which, democratization incorporates the norms and values of the societies in question. The article begins with a brief overview of some of the problems associated with defining peace. We suggest that peace should be looked at as a universal value, as democracy has been in the recent past. We provide a more detailed theoretical assessment of the linkage between democracy and peace. Our general argument is illustrated in the South Asian, specifically the Indian, context.     

“Racial Threat”, Partisan Climate, and Direct Democracy: Contextual Effects in Three California Initiatives

Does context—racial, economic, fiscal, and political—affect whites’ votes on racially-related ballot propositions? We examine non-Hispanic whites’ voting behavior on three California ballot initiatives: Propositions 187, 209, and 227. Unlike previous analyses that lacked individual-level data and were therefore limited to ecological inference, we combine individual-level data from exit polls with county-level contextual variables in a hierarchical linear model. Racial/ethnic context affected whites’ votes only on Proposition 187, economic context had no influence on vote choice, and the effect of fiscal context was limited to Proposition 227. However, across the propositions, whites’ decisions were shaped by their political context. Thus, we do not find support for the “racial threat” hypothesis across all racially-charged issues.     

Occupational identity status development,gender comparisons,and internal-external control in first-year air force cadets

This study of cadets at the United States Air Force Academy during their first six months assessed the pattern of developmental changes in occupational identity status for males and females, examined the relationship of internal-external control to identity statuses, and discussed the data in terms of Erikson's proposals and factors involved in gender differences in identity development. More than half of the cadets entering the academy were in uncommitted occupational identity statuses. Over the time period, half the cadets remained in their identity statuses, with the Foreclosed cadets the most stable and Achieved the least stable. The expected changes in the Achieved identity status, and other changes, established a pattern of identity development congruent with Erikson's theory of developmental progress or regression in identity formation. Only male cadets demonstrated significant changes into or out of a status, and significant associations between their identity statuses and internal-external control, with more internally controlled males being Achieved and more externally controlled males being Diffused-diffused.The views expresed in this article are the author's and do not necessarily reflect those of the United States Air Force or the United States Air Force Academy, Colorado Springs, Colorado.Received Ph.D. from State University of New York at Buffalo.
