    In the last three plus decades, considerable attention has been given to certain common phases in the life cycle of gatherings, demonstrations, and riots in the United States. Much of the study focuses on theoretical origin and social psychology associated with each type of event. There is considerably less empirical work regarding police reaction to these events, particularly concerning celebratory behavior following a sporting event. Celebratory incidents are less organized than their protests counterpart. A variety of fans with collective zeal gather in a common location without leadership or mission. Celebratory behavior has become commonplace amongst fans in cities with sports teams competing for prestigious victories in nearly all types of sporting contests. Post-game celebration may have a ritualized aspect and be institutionalized, in the sense that participants and controllers expect them to happen. For public order maintenance, the strategic orientation used by police for celebratory crowds following these events has predominantly been paramilitary in nature both from an appearance and behavior aspect. Some research and social theory argue that a systemic culture of militarization in American police makes these incidents worse. To aid in this research a micro level case study from Lexington, Kentucky will examine post-games from two Final Four tournament years of celebratory behavior and the evolving strategies of police. Brief comparisons of police response from other agencies are discussed and analyzed with Lexington police response. Evolving police tactics and social theory combine to suggest that a relationship oriented response may be favored over a tactical approach to reduce crowd agitation or aggressive behavior during post-game celebration. Finally, considerations of police tactics toward a more relationship-oriented response are discussed

    Expanding Pharmacotherapy Data Collection, Analysis, and Implementation in ERAS\u3csup\u3eĀ®\u3c/sup\u3e Programsā€”The Methodology of an Exploratory Feasibility Study

    Get PDF
    Surgical organizations dedicated to the improvement of patient outcomes have led to a worldwide paradigm shift in perioperative patient care. Since 2012, the Enhanced Recovery After Surgery (ERASĀ®) Society has published guidelines pertaining to perioperative care in numerous disciplines including elective colorectal and gynecologic/oncology surgery patients. The ERASĀ® and ERAS-USAĀ® Societies use standardized methodology for collecting and assessing various surgical parameters in real-time during the operative process. These multi-disciplinary groups have constructed a bundled framework of perioperative care that entails 22 specific components of clinical interventions, which are logged in a central database, allowing a system of audit and feedback. Of these 22 recommendations, nine of them specifically involve the use of medications or pharmacotherapy. This retrospective comparative pharmacotherapy project will address the potential need to (1) collect more specific pharmacotherapy data within the existing ERAS Interactive Audit SystemĀ® (EIAS) program, (2) understand the relationship between medication regimen and patient outcomes, and (3) minimize variability in pharmacotherapy use in the elective colorectal and gynecologic/oncology surgical cohort. Primary outcomes measures include data related to surgical site infections, venous thromboembolism, and post-operative nausea and vomiting as well as patient satisfaction, the frequency and severity of post-operative complications, length of stay, and hospital re-admission at 7 and 30 days, respectively. The methodology of this collaborative research project is described

    Stratigraphy, Radiocarbon Dating and Culture History of Charlie Lake Cave, British Columbia

    Get PDF
    Three seasons of fieldwork at Charlie Lake Cave, British Columbia, have revealed a sequence of stratified deposits that spans the Late Pleistocene and entire Holocene. Analyses of sediments, radiocarbon dates, faunal remains, and artifacts show that the site was first occupied by people at about 10 500 B.P., when local environments were more open than today. By 9500 B.P., boreal forest had moved into the area, and human use of the site was minimal until about 7000 B.P., when a brief occupation of the site probably included a human burial. Use of the site intensified after about 4500 B.P., possibly because the cave became more accessible. The site was used both as a residential base camp and as a more temporary hunting station or lookout.   Article Summary by Jonathan C. Driver, May 2015   After we had completed our excavations in 1991 we decided that we should focus on writing up what we had excavated, and not undertake further excavations at the site. This paper was written to summarize our state of knowledge about the archaeological remains at the site, and focused on describing the stone tools, the overall stratigraphy, and the dating. The stratigraphic summary replaced earlier work based on the 1983 excavations, and we were able to refine our dating of the site as a result of more radiocarbon dates. The different cultural periods were based mainly on the work done by Martin Handly for his M.A. thesis at Trent University. The long list of authors reflects the need for a team approach to archaeological work, and include the project directors (Knut Fladmark and Jon Driver), stone tool analysis and development of the cultural sequence (Martin Handly), animal bone analysis (Randall Preston and Jon Driver), sediment analysis (Greg Sullivan and Knut Fladmark), and radiocarbon dating (Erle Nelson). The most important aspect of the site is that it preserves a very rare record of humanly made artifacts dating from the end of the last ice age (at least 10,500 BC) to very recent times. The many layers at the site allow us to separate the different cultural periods. Good preservation of bone allowed us to submit radiocarbon dates that provide approximate ages for the various cultures that used the site. The artifacts that exhibit the most change through time are projectile points ā€“ the sharp stone tips for spears, darts and arrows. In much of western Canada it is difficult to date archaeological sites, because many of them are found in shallow soils where radiocarbon dating is difficult for two reasons. First, animal bone is often not preserved due to the acidic nature of the soils. Second, although charcoal is often found, it cannot be reliably associated with human activity, because natural forest fires also produce charcoal. As a result, archaeologists look at the style of the projectile points to assign approximate ages. Tseā€™Kā€™wa provides an opportunity to link artifacts of different styles to radiocarbon dates in a site with many distinct layers. So Tseā€™Kā€™wa is a foundation for understanding the sequence of different cultures in the region. The article also discusses the possible early presence of microblade technology. Microblades are the most efficient way of producing a cutting edge when the base technology is chipped stone. A small piece of high-quality raw material (known as the core) is shaped in such a way that numerous parallel-sided slivers of stone can be removed. These ā€œmicrobladesā€ can then be hafted in wood or antler to form knives or arrow barbs. The concept is rather like our utility knives that have replaceable blades. This technology allows people to carry small quantities of high quality stone with them, ensuring that they always have a sharp blade available. Not all archaeologists agree that the early microblade core from Tseā€™Kā€™wa is part of this technology, because it doesnā€™t conform to the classic methods of core manufacture. However, we argue that evidence for the removal of microblades is very obvious, and the lack of classic core preparation is because of the tabular nature of the raw material. The paper also introduces some information about animal bones, including the raven burials, evidence for environmental change, and the presence of collared lemming. These topics were subsequently explored in more detail in other papers

    Assessing Smoking Behaviour and Tobacco Smoke Exposure: Definitions and Methods

    Get PDF
    AbstractIn recent years, the increased availability of tobacco products other than conventional cigarettes, the use of puffing topography devices for smoking behaviour studies and the use of biomarkers to study smoke constituents exposure have generated the need for a more comprehensive set of definitions concerning smoking behaviour and exposure to smoke. The definitions offered in this paper are based on many years of practical experience and on consensus within a broad group of scientists working in these areas. It is intended that, with wider and more consistent usage, these definitions should reduce any misunderstandings and facilitate interpretation of future studies

    Wikipedia as an encyclopaedia of life

    Get PDF
    In his 2003 essay E O Wilson outlined his vision for an “encyclopaedia of life” comprising “an electronic page for each species of organism on Earth”, each page containing “the scientific name of the species, a pictorial or genomic presentation of the primary type specimen on which its name is based, and a summary of its diagnostic traits.” Although the “quiet revolution” in biodiversity informatics has generated numerous online resources, including some directly inspired by Wilson's essay (e.g., "http://ispecies.org":http://ispecies.org, "http://www.eol.org":http://www.eol.org), we are still some way from the goal of having available online all relevant information about a species, such as its taxonomy, evolutionary history, genomics, morphology, ecology, and behaviour. While the biodiversity community has been developing a plethora of databases, some with overlapping goals and duplicated content, Wikipedia has been slowly growing to the point where it now has over 100,000 pages on biological taxa. My goal in this essay is to explore the idea that, largely independent of the efforts of biodiversity informatics and well-funded international efforts, Wikipedia ("http://en.wikipedia.org/wiki/Main_Page":http://en.wikipedia.org/wiki/Main_Page) has emerged as potentially the best platform for fulfilling E O Wilson’s vision
