Driving the wrong way on freeways has been a nagging traffic safety problem since the interstate highway system was founded in the 1950s. Despite four decades of highway striping and sign improvements at freeway interchanges, the problem persists. This paper is to determine the contributing factors to wrong-way driving on freeways and to develop promising, cost-conscious countermeasures to reduce this driving errors and related crashes. Wrong-way crash data from Illinois Department of Transportation (IDOT) crash database were collected with 632 possible wrong-way crashes. The real wrong-way crashes were further identified by reviewing the wrong-way crash reports hardcopies and information from other resources. Characteristics of wrong-way driving behaviors were analyzed and statistical analyses were conducted to identify the contributing factors of wrong-way crashes on freeway. The state-of-the-art roadway safety management process recommended by the Highway Safety Manual (HSM) was adopted to diagnose the wrong-way driving behavior on Illinois freeway and develop the specific wrong-way crashes management procedures. The first three steps, network screening, diagnosis and countermeasure selection was developed in details. The whole procedure developed could be used to guide the management of freeway wrong-way crashes in the future. The specific procedure of transportation network review, candidate location identification and site ranking for freeway wrong-way crashes was established firstly. Based on the collected wrong-way crash data, the safety performance function (SPF) for wrong-way crashes on freeway was developed with the annual average daily traffic (AADT) and segment length being the independent variables. The procedures for candidate wrong-way crash sites diagnoses with crash data, historic site data, field condition and other information were described step by step. The methods for contributing factors identification were proposed and the Haddon matrix for wrong-way crashes on freeway was constructed finally. Methods for selecting wrong-way crash countermeasures from the perspective of "four E's" based on crash analysis finding, site-specific contributing factors and geographical characteristics were discussed, and research needs on wrong-way crash management in the future were recommended finally.

The global over-the-counter derivatives market reached a staggering 14.5 trillion US dollars in gross market value at the end of December 2007. Although OTC derivatives are extremely useful and versatile in transferring risks, it appears to be a double-edged sword. For every derivative transaction concluded in the OTC market, there are two parties involved – each of which is exposed to the other defaulting on the agreed terms and conditions of the contract. Counterparty credit risk is defined as the loss that will be incurred in the event that a counterparty fails to honour its financial obligations. This dissertation provides an overview of counterparty credit risk measurement from a theoretical point of view and puts an emphasis on the demonstration of the current solutions used in practice to address this problem. The author applies a bottom up approach to the problem by defining counterparty credit risk exposure on a contract (single-trade) level and expands this definition on a step-by-step basis to incorporate portfolio effects, such as correlation among underlying market variables as well as credit risk mitigation techniques, such as netting and collateral agreements, in measuring counterparty credit risk exposure on a counterparty level. The author also discusses related concepts which impact counterparty credit risk such as wrong-way risk and proposes an enhancement to the framework introduced by Finger (2000) for incorporating wrong-way risk into existing measures of counterparty credit risk exposure. Finger‟s framework is enhanced by the introduction of a structural model approach which can be used in establishing a functional and intuitive relationship between the probability of default of the counterparty and the underlying market variable to the derivative contract under consideration. This approach is also applied to a typical South African situation through the use of Monte Carlo simulation. The topic of counterparty credit risk modelling is a very relevant topic in modern finance, especially since the advent of Basel 2 which this dissertation also touches on in terms of the applications of counterparty credit risk modelling and how this relates to the minimum regulatory capital requirements set by bank regulators.

How did the wrong-body discourse (WBD) become the dominant medicalised discourse in Canada and the United States? What ideological effects did this dominance have? To address these questions, I conducted a critical discourse analysis informed by Foucauldian genealogy. I analysed texts written in, or translated into, English for a medical-expert audience from the earliest mentions of wrong bodies in 1864 to the institutionalisation of the WBD in the DSM-III diagnosis of transsexualism in 1980. I argue that through the medicalisation of gender variance, the three tenets of the WBD—wrongness of the body; disjuncture between sex and gender; surgical and hormonal solution—developed individually and were brought together by medical experts into a coherent discourse in the mid-1960s. Two main factors likely contributed to the dominance of the WBD: the lack of dependence on any particular etiology that made the WBD compatible with a wide variety of explanations, and the very small number of medical experts responsible for the majority of publications on gender variance all using the WBD. I further argue that medical experts, faced with challenges to their treatment of gender-variant people, turned to the idea of true transsexualism to stabilise the newly-formed WBD and legitimate their treatment of gender variance. In addition to the three tenets of the WBD, true transsexualism also included characteristics and assumptions that medical experts expected gender-variant people to embody if they wanted access to treatment. Through these expectations, medical experts produced a set of norms against which all gender-variant people were judged as legitimate or not, namely, one of the first iterations of transnormativity. / Graduate

The First Amendment gives U.S. citizens a Hohfeldian legal immunity that disables Congress from removing citizens’ legal liberty to criticize the government. Any attempt by Congress to remove this liberty would fail, but such an attempt would still wrong citizens. The familiar concept of claim-violation does not fully account for this wrong. Claims name actions that ought not be performed and are violated when those actions are performed. Immunities names actions that cannot be performed. Congress would wrong citizens not by doing something it ought not do but by attempting and failing to do something it cannot do. Using elements of Jean Hampton’s expressive theory of punishment, I analyze Congress’ attempt (and other similar acts) as an expressive act that denies the existence of immunities. Congress’ immunity-“contradiction” would wrong U.S. citizens by denying the value that generates the immunity, by causing damage to the acknowledgement of the citizens’ value, and by threatening the existence of the immunity.

A Study on Students¡¦ Wrong Chinese Characters in Elementary Schools Educational Priority Area of Kaohsiung City Pao-Kuei Wu Chao-Kai Yuan Abstract This research mainly discusses the topic of miswritten or wrong Chinese characters in elementary schools within educational priority area (EPA), and collected sample based upon the gradual competence indicators set by the Educational Administration ministry for national language(Chinese) courses of the National Nine-Year Curriculum for elementary and junior high schools. Specifically, 3rd and 6th graders¡¦ Chinese writing tests were examined, and the wrong characters were categorized into three parts according to character structure, character strokes, and stroke-order. In the material analysis, the data are being processed according to descriptive statistics, product-moment correlation , and the t-test statistical methodology. The results are the following: 1. EPA¡¦s quantity of vocabulary knowledge and wrong character type has a negative correlation. 2. For EPA¡¦s quantity of vocabulary knowledge and orthographic classification, the Character-structure component, and three is a negative correlation between qubntity of vocabulary knowledge and non-structures components. 3. For EPA¡¦s orthographic classification and wrong character category , there is a negative correlation between the root of the character and characters that lacked strokes.there is a positive correlation between the the non-structures component and characters that had additional strokes.Similar character parts and characters that either had additional or less strokes have a negative correlation. 4. According to the competence indicators of the Nine-Year Curriculum, recogniction of the classification of the root of the character at the first stage is not apparent. Recognition at the second stage of the classification of the character root is more apparent, while there is a limited recognition of change in character structures. 5. Within the EPAs as the accumulation of vocabulary knowledge increases with age, it is possible to perceive gradually the characteristics of orthographic structures, but recognition development is still slow. The following is suggested based upon the research result: 1. The students¡¦ habit of using a dictionary should be nurtured, and the method of looking up a character by its character root should be encouraged. 2. In teaching new vocabulary, the character radical classification and structure principle should be used to help recognize the character. 3. It is suitable to use the ¡§ distribution practice¡¨. 4. ¡§Part teaching¡¨and the editing of character-source teaching material should be motivated. 5. Calligraphy education and using the blackboard to teach should be advocated and utilized.

Master of Science / Department of Civil Engineering / Eric J. Fitzsimmons / Transportation officials continuously seek to prevent and reduce wrong-way crashes on interstate highways in the United States. These crashes typically have a high probability of head-on vehicle crashes, resulting in fatalities or serious injuries due to excessive vehicle speeds, and decreased room to maneuver because of fixed barriers or rough shoulders. This research project studied wrong-way crashes on interstate highways in Kansas in order to determine what, if any, statistically significant variables contribute to wrong-way driving crashes. Although these crashes represented only 0.05 percent of all vehicle crashes in Kansas in 2015, wrong-way crashes were found to have a higher rate of fatalities and injuries. In Kansas, 22.6 percent of all crashes and 56 percent of all wrong-way crashes resulted in fatalities and injuries, even though typical vehicle crashes in Kansas occur at non-intersection locations in daylight or in the presence of streetlights without negative factors of adverse weather conditions or drivers influenced by alcohol or drugs. Using crash data provided by the Kansas Department of Transportation from the years 2005 to 2015, the research team examined 372 wrong-way crashes. A cumulative logit statistical model was developed to identify significant characteristics of variables associated with each wrong-way crash. Results showed that driver not under the influence of alcohol or drugs was a significant characteristic in fatal and injury wrong-way crashes. Additionally, certain days of the week were associated with decreased vehicle crash rates when compared to the reference category.

Counterparty credit risk is an important type of financial risk. The importance of proper counterparty risk management became most apparent in the wake of the 2008 series of failures of several large banks. Correlation of market factors is an important issue in the calculation of CVA. A notable case of correlation is wrong-way risk which occurs whenever the probability of default of the counterparty is positively correlated with exposure. The basic formulas for CVA and basic counterparty credit risk models do not account for wrong-way risk because its modeling is nontrivial. This thesis aims to answer how well can the impact of wrong-way risk on CVA be approximated with an add-on which only depends on correlation between the price of the underlying asset and the credit spread of the counterparty. The thesis is supplemented by a fully documented implementation of the model in the Mathematica software.

Counterparty Credit Risk and Interest Rate Derivatives Pricing Jakub Černý Abstract: This thesis deals with the pricing of OTC financial derivatives including the coun- terparty credit risk (CCR). It focuses on the interest rate derivatives for which the interest rate must be modeled as random. This is where they differ from the pricing of other derivatives. The credit valuation adjustment (CVA) concept is used to calculate CCR which is in line with current banking regulation Basel III. When we assume the independence of the underlying asset and the credit quality of the counterparty, we obtain an analytical expression of CVA. However, if the independence is violated, the CVA calculation becomes quite complicated. Specifically, the CVA of the inter- est rate swap (IRS) is calculated mainly using the simulation approach which is time and computationally consuming. Therefore, we bring two new methods for IRS CVA calculation where the CVA is expressed in a semi-analytical form. These methods use copula functions, particularly the Gaussian copula and the upper Fréchet bound, and we compare them numerically with a complex simulation study. Furthermore, we pro- pose a method of calibration of the correlation coefficient and we determine the impact of changes in the intensity of default on the final CVA with four...

AIM: To conduct a systematic literature review on the existing literature on the prevalence of medication errors across the medicines management system in primary care; To explore the systems of error management in primary care; to investigate the prevalence and nature of medication errors in children, 0-12 years, and in older patients, ≥65 years, in primary care; and to explore community pharmacists' interventions on medicines-related problems. METHODS: 1) Systematic literature review; 2) Questionnaire survey of Primary Care Trusts (PCTs), Clinical Commissioning Groups (CCGs) and NHS Area Teams; 3) Retrospective review of the electronic medical records of a random sample of older patients, ≥65 years old, and children 0-12 years old, from 2 general practices in Luton and Bedford CCGs, England; 4) Prospective observation of community pharmacists' interventions on medicines-related problems and prescribing errors from 3 community pharmacies in Luton and Bedford CCGs in England. DATA ANALYSIS: Quantitative data from records review were analysed using Microsoft Excel on data extracted from an Access database. Statistical tests of significance were performed as necessary. Descriptive statistics were conducted on quantitative data from the studies and inductive qualitative analyses were conducted on aspects of the questionnaire survey. RESULTS: • The systematic literature review demonstrated that medication errors are common, and occur at every stage of the medication management system in primary care, with error rates between ≤1% and ≥90%, depending on the part of the system studied and the definitions and methods used. There is some evidence that the prescribing stage is the most susceptible, and that the elderly (over 65 years) and children (under 18 years) are more likely to experience significant errors, although very little research has focussed on these age groups. • The questionnaire survey of PCTS, CCGs and NHSE demonstrated that national and local systems for managing medication errors appeared chaotic, and need to be better integrated to improve error learning and prevention in general practice. • The retrospective review of patients' medical records in general practices demonstrated that prescribing and monitoring errors are common in older patients and in children. 2739 unique prescription items for 364 older patients ≥65 years old were reviewed, with prescribing and monitoring errors detected for 1 in 3 patients involving about 1 in 12 prescriptions. The factors associated with increased risk of errors were: number of unique medications prescribed, being ≥75 years old, being prescribed medications requiring monitoring, and medications from these therapeutic areas: corticosteroid, NSAID, diuretic, thyroid and antithyroid hormones, statins and ACE-I/ARB. 755 unique prescription items for 524 younger patients 0-12 years old were examined, with approximately 1 in 10 prescriptions and 1 in 5 patients being exposed to a prescribing error. Factors associated with increased risk of prescribing errors in younger patients were: being aged ≤10 years old, being prescribed three or more medications, and from similar therapeutic areas as above. Majority of the errors were of mild to moderate severity. • Community pharmacists performed critical interventions as the last healthcare professional defense within the medicines management system in primary care. However, this role is challenged by other dispensary duties including the physical aspects of dispensing and other administrative roles. CONCLUSION Prescribing and monitoring errors in general practice, and older patients and children may be more at risk compared to the rest of the population, though most errors detected were less severe. Factors associated with increased risk for errors in these age groups were multifaceted. The systems for periodic laboratory monitoring for routinely prescribed drugs, particularly in older patients, need to be reviewed and strengthened to reduce preventable hospital admissions. Antibiotic dosing in children in general practice needs to be regularly reviewed through continued professional developments and other avenues. As guidance on local arrangements for error reporting and learning systems are less standardised across primary care organisations, pertinent data from adverse prescribing events and near misses may be lost. Interventions for reducing errors should therefore explore how to strengthen local arrangements for error learning and clinical governance. Community pharmacists and/or primary care pharmacists provide an important defence within the medicines management system in primary care. Policy discussions and review around the role of the pharmacist in primary care are necessary to strengthen this defence, and harness the potential thereof.
