Study On Crash Characteristics And Injury Severity At Roadway Work Zones

Wang, Qing 26 March 2009 (has links)
In USA, despite recent efforts to improve work zone safety, the number of crashes and fatalities at work zones has increased continuously over several past years. For addressing the existing safety problems, a clear understanding of the characteristics of work zone crashes is necessary. This thesis summarized a research study focusing on work zone traffic crash analysis to investigate the characteristics of work zone crashes and to identify the factors contributing to injury severity at work zones. These factors included roadway design, environmental conditions, traffic conditions and vehicle/driver features. Especially, special population groups, which divided into older, middle Age, and young, were inspected. This study was based on history crash data from the Florida State, which were extracted from the Florida CAR (Crash Analysis Reporting) system. Descriptive statistics method was used to find the characteristics of crashes at work zones. After then, an injury severity predict model, using the ordered probit regression technology, was developed to investigate the impacts of various factors on different the injury severity at work zones. From the model, it can be concluded that some factors, including the road section with curve, alcohol/drugs involved, a high speed, angle crash and too young or old drivers are more likely to increase the probability of angle crashes. Based on the magnitudes of the variable coefficients, the factor of maximum posted speed have a great impact to injury severity, which shows restriction to driving speed is principle countermeasure for improving work zone safety.

Outcome of Stroke Prevention : Analyses Based on Data from Riks-Stroke and Other Swedish National Registers

Åsberg, Signild January 2012 (has links)
The aim of this thesis was to explore variations in stroke prevention and the effect of prevention on outcome. The studies were based on patients registered in the Swedish Stroke Register between 2001 and 2009 and although used to different extents in each paper, additional information was retrieved through linkage to The National Patient Register, the Cause of Death Register, the Prescribed Drug Register and the Total Population Register. Cardiovascular risk factors were prevalent among ischemic stroke (IS) patients; however, they were not always prescribed the drugs recommended, and increasing age was an important negative predictor (Paper I). After IS, the rate of hemorrhage in patients prescribed antiplatelet agents (2.4 per 100 person-years) was double to results from randomized controlled trails, but was similar for patients prescribed warfarin (2.5 per 100 person-years).  Age ≥75 years and previous hemorrhage were associated with a moderately increased risk of future hemorrhage (Paper II). Among IS patients with atrial fibrillation, one-third was prescribed warfarin and two-thirds were prescribed antiplatelets. After adjustment for a propensity score (used to adjust for the non-randomized design), warfarin was associated with a reduced risk of death (0.67; 95% CI, 0.63-0.71) (Paper III). The rate of subsequent hemorrhagic stroke was 0.4 per 100 person-years and the risk did not change (HR 1.04; 95% CI, 0.73-1.48) when later years of the 2000s (inclusion period 2005-8: follow-up until 2009) was compared with earlier years (inclusion period 2001-4: follow-up until 2005) (Paper IV, cohort). Although the risk of first-ever hemorrhagic stroke more than doubled with warfarin than without, the risk did not change between 2006 and 2009 (Paper IV, case-control). In summary, the prescription of secondary preventive drugs varies with age, even though cardiovascular risk factors are prevalent in all ages. The risk of death and hemorrhage are affected by the type of antithrombotic prescribed. Therefore, it is important individual’s stroke and bleeding risks in stroke prevention are assessed.

”Nätdejting för olika åldrar” : En studie om Internet och dejting / Netdating for different ages

Nekmouche, Henri January 2009 (has links)
Title: Nätdejting för olika åldrar (Netdating for different ages)Author: Henri NekmouchePurpose: The purpose of this study is to investigate what influence the medium Internethas had on building up relationships between people who have dated online, and tocompare two different age groups.Method/Material: In this study the author has conducted personal interviews with sixpeople who all have experienced Internet dating, and had their first contact with agirlfriend/boyfriend online. The questions asked were designed to help answering thepurpose of the study.Main results: This study shows that in general there is a positive view of Internet datingamong both groups. They appreciate the opportunities it provides, as they get to knowthe other persons personality first. Even so, it should be noted that they still tend to be abit ashamed to talk about Internet dating, and some don’t want to be associated with it.The communication pattern tend to be pretty much the same among both groups. Thereare differences between the two age groups in terms of the way of dating online – theuse of pictures, sites and programs differs, and the reasons for this are many. Two of thebiggest reasons can be related to the question whether the person grew up with theInternet or not; and also to the fact that older people tend to be more serious when theyuse online dating because their time is runing out.Number of pages: 44Course: Media and Communication studies CUniversity: Division of Media and Communication, Department of Information Science,Uppsala UniversityPeriod: Fall 2009Tutor: Amelie HössjerKeywords: Internet dating, communication, chat, communities, different age group
