Master of Science / Civil Engineering / Hayder Rasheed / Reverse diagonal shear cracking at the supports of many reinforced concrete girders is a phenomenon affecting a number of KDOT’s low-volume bridges built in the early-to-mid 1900’s. This phenomenon is not addressed in the AASHTO Bridge Design Manual (2002) or ACI specifications. This study investigates the causes of this cracking and creates BRIDGE (Bridge Rating of Inclined Damage at Girder Ends), an Excel-based software to determine the load rating of a user specified bridge exhibiting reverse diagonal shear cracking at the girder supports. A user-interface is created which allows a user to create a grillage model of an existing bridge and to place various rating trucks on the bridge. Equivalent flexibility analysis is used to distribute the truck live loads from within the deck panels to the surrounding girders and diaphragms. Stiffness matrices are utilized to find the nodal displacements then the reactions at the girder supports caused by the truck live loads and bridge dead load. These reactions are checked against RISA software models to test the accuracy of the stiffness matrix application. ABAQUS FE models and Mohr’s circle stress distribution is used to find the driving and clamping forces on the crack. These forces are caused by resolving the dead and live load reactions and the friction force generated between the concrete girder and the rusty steel bearing pad along the shear crack orientation. These clamping and driving forces are used, along with the simplified modified compression field theory to determine the shear capacity of each girder at the reverse cracks. A modified version of Equation 6B.4.1 from the Manual for Bridge Evaluation (2011) is used to find the operating and inventory rating factors for the bridge.

Older adults with dementia are at increased risk of becoming incapable of making their own decisions and may therefore benefit from planning for care at the end-of-life. Advance care planning (ACP) is a complex, multifaceted process by which people can express their wishes about care at the end-of-life in case they become incompetent to make decisions for themselves. However, we have little understanding of the ACP process among people with dementia and their families. This study addressed three questions: 1) when and how to cognitively impaired older adults and their families receive information about ACP; 2) in which aspects of the ACP process do families of cognitively impaired older adults engage, and why (and does this fit within the framework of the transtheoretical model of behaviour change [TTM]); and 3) how ACP relates to the way in which family members perceive the quality of death of their loved one. 22 family members of deceased older adults with dementia were interviewed and data was analyzed using interpretive description qualitative methods. Participants reported that information about ACP is provided in a haphazard and often incomplete manner, leading to difficulty engaging in the ACP process. Older adults were in various stages of readiness to engage in ACP behaviours, with most only engaging in a subset of ACP behaviours. Although ACP was viewed as beneficial by participants, several barriers were identified that prevented people with dementia from dying in a way that was aligned with previously-expressed wishes. Implications for the practice of clinical neuropsychology and implications for policy on ACP are discussed. / Graduate

The Front End of Innovation (FEI) is the early phase of the Product Development Process, responsible for the concept generation and an important driver of innovation success. The FEI is characterized by roles\' dynamism, ambiguity, and uncertainty. Several authors divide the FEI into other sub-phases in order to organize its activities, roles, and understand the function of each role. Despite the growing research about the FEI in recent years, there is a need for further research on the theme to better understand the dynamics and help to reduce the uncertainty in the critical concept phase. The formal processes designed for the front end are insufficient, the rules and roles are not fully described, and it is necessary to balance the interactions between the activities in the FEI to get a better-structured New Product Development - NPD - later. The main FEI models developed at the literature have discussed some key roles such marketing, engineering, customers, but they do not discussed the role of design, which is critical in creative activities which, in turn, are the nature of the new product development process. The literature also has not discussed the external integration in the FEI, that is, how the Brand Owners integrate the partners, especially the suppliers and design agencies, in this critical and uncertain phase. To tackle this issue, this research aims to examine the FEI in a dynamic industry, examining the integration of roles in an iterative process. The objective of this research is to identify the roles that play in the Front End of Innovation and the mechanisms of integration, whether internal through cross-functional teams; or external through interfirms integration. The main question that guided this research is \"What roles are involved in each FEI activity and what are the mechanism that integrate these roles in the FEI?\". This is qualitative and exploratory research, based on multiple-cases-studies. For this study, the packaging industry was selected because of its value chain in the concept phase, which has a complex set of relationships among its parties, Brand Owner, Design Agencies and Packaging Producers. The consumers buy the product by the performance of the same and also by the packaging. Packaging is considered a second product at the point of sale and a vital buying decision factor. Brand Owners understand that they need to integrate suppliers into the FEI to assist them in identifying opportunities, ideation, and conceptualization. Five brand owners were interviewed, and the FEI has been divided into five activities: Opportunity Identifications and Analysis, Idea Generation, Idea Enrichment, Idea Selection, and Concept Development. / O Front End de Inovação (FEI) é a fase inicial do processo de desenvolvimento de produtos, responsável pela geração de conceitos e um importante motor de sucesso na inovação. O FEI caracteriza-se pelo dinamismo, a ambiguidade e a incerteza dos papéis. Vários autores dividem o FEI em outras subfases, a fim de organizar suas atividades, papéis e compreender a função de cada função. Apesar da crescente pesquisa sobre o FEI nos últimos anos, há necessidade de novas pesquisas sobre o assunto para entender melhor a dinâmica e ajudar a reduzir a incerteza na fase conceitual crítica. Os processos formais projetados para o front-end são insuficientes, os papéis e as regras e não são totalmente descritos e é necessário equilibrar as interações entre as atividades no FEI para obter um melhor estruturado Desenvolvimento de Novos Produtos - NPD - depois. Os principais modelos de FEI desenvolvidos na literatura discutem alguns papéis fundamentais como marketing, engenharia, consumidores, mas não discutem o papel do design, crítico nas atividades criativas, que, por sua vez, são a natureza do processo de desenvolvimento de novos produtos. A literatura também não tem discutido a integração externa no FEI, ou seja, como os clientes integram os parceiros, especialmente os fornecedores e agências de design, nesta fase crítica e incerta. Para abordar esta questão, esta pesquisa visa examinar o FEI em uma indústria dinâmica, examinando a integração de papéis em um processo iterativo. O objetivo desta pesquisa é identificar os papéis que desempenham no Front End de Inovação e os mecanismos de integração, sejam eles internos através de equipes multifuncionais; ou externos através da integração entre firmas. A principal questão que guiou esta pesquisa é \"Quais papéis estão envolvidas em cada atividade do FEI e quais são os mecanismos que integram estes papéis no FEI?\" Trata-se de uma pesquisa qualitativa e exploratória, baseada em estudos de casos múltiplos. Para este estudo, o setor de embalagens foi selecionado por sua cadeia de valor na fase conceitual, que possui um conjunto complexo de relacionamentos entre suas partes, as Indústrias de Bens de Consumo, as Agências de Design e os Produtores de Embalagens. Os consumidores compram o produto pela performance do mesmo e também pela embalagem. A embalagem é considerada um segundo produto no ponto de venda e um fator de decisão de compra vital. As Indústrias de Bens de Consumo entendem que precisam integrar fornecedores no FEI para ajudá-las a identificar oportunidades, ideação e conceituação. Foram entrevistados cinco Indústrias de Bens de Consumo e o FEI foi dividido em cinco atividades: Identificações e Análises de Oportunidades, Geração de Ideias, Enriquecimento de Ideias, Seleção de Ideias e Desenvolvimento de Conceitos.

This research investigated the library end-users' perceptions of their training needs in relation to using the electronic information resources in selected public universities in Malaysia. It also investigated the training methods preferred by end-users in learning how to use electronic information resources. The subjects of the study were university students and academic staff from three selected public universities in Malaysia. They comprised 433 students and 223 academic staff. This study employed both quantitative and qualitative methods. The main data was gathered through self-administered questionnaires, while the supplementary data was gathered through face-to-face semi-structured interviews. Opinions from the librarians responsible for end-user training at the three university libraries were also sought through face-to-face semi-structured interviews. Comparisons were made between the two groups of end-users, namely, students and academic staff in areas related to the problems of the study. Appropriate non-parametric statistical techniques such as cross-tabulation, chisquare test, Mann-Whitney U test and Spearman correlation test were applied in analysing the data measured at both nominal and ordinal scales. Among the major findings were: (1) a statistically significant differences were found between students and academic staff in terms of knowledge and ability in using electronic information resources. Many academic staff were more knowledgable and able to use electronic information resources than students. However, concerning knowledge in using certain IT facilities, many more students than academic staff knew how to use them; and (2) both students and academic staff preferred one-to-one training methods as their first choice. With regard to the second choice of training method, students preferred computerassisted instruction (CAI), while academic staff preferred library workshops with hands-on training. Recommendations based on the research findings were made.

This study contributes to our understanding of the innovation process by bringing attention to and investigating the process by which innovators outside of firms obtain innovation-related resources and assistance. This study is the first to explicitly examine how user-innovators gather the information and assistance they need to develop their ideas and how they share and diffuse the resulting innovations. Specifically, this exploratory study analyzes the context within which individuals who belong to voluntary special-interest communities develop sports-related consumer product innovations. We find that these individuals often prototype novel sports-related products and that they receive assistance in developing their innovations from fellow community members. We find that innovation-related information and assistance, as well as the innovations themselves, are freely shared within these communities. The nature of these voluntary communities, and the "institutional" structure supporting innovation and free sharing of innovations is likely to be of interest to innovation researchers and managers both within and beyond this product arena.(author's abstract)

Class of 2014 Abstract / Specific Aims: The main objectives of the study are to compare the number of antihypertensive medications upon admission versus discharge, determine the fluctuation index ((SBPmax – SBPmin)/Avg)x100) between inpatient HD sessions, determine the minimum SBP during each inpatient HD session and compare pre-HD weight to post-HD weight for each inpatient HD session to determine inter-dialytic weight gain. The findings of this study are expected to have a positive impact on the management of blood pressure and fluid overload in HD patients by identifying the adverse effects associated with an increased anti-hypertensive medication burden. Methods: The Institutional Review Board approved this retrospective chart review. The electronic medical record system identified patients that received HD between January 1, 2010 and January 1, 2013. The following data was collected: the admission diagnosis and patient comorbidities; time on dialysis prior to admission and time since last HD session; the number and class of anti-hypertensive medications documented on admission, while inpatient, and upon discharge; the use of midodrine, receipt of erythropoietin stimulating agents, total time on dialysis while admitted, intra-dialytic hypotensive events, blood pressure readings pre- and post-HD, and inter-dialytic weight gain. Descriptive and demographic variables were also collected from the electronic medical record systems. The investigators will use this information to compare the number of anti-hypertensive medications upon admission versus discharge, determine the fluctuation of systolic blood pressure (SBP) between each inpatient HD session, determine the minimum SBP during each inpatient HD session and compare pre-HD weight to post-HD weight to determine inter-dialytic weight gain and total volume removed per each HD session. Descriptive statistics will be used to analyze our demographic data. Multiple linear regression analyses will be completed to evaluate independent predictors of inter-dialytic weight gain and intra-dialytic hypotension. Main Results: Pending Conclusion: Pending

Biological pre- and postharvest disease control strategies depend on successful colonisation and survival of the introduced antagonists on the infection court. Effective and economical applications involve targeting the antagonists where they are critically needed i.e. the infection court. Honeybee dispersal is one method of antagonist application to such specific sites. In view of this, an in vitro experiment was conducted to investigate attachment, colonisation and survival of Bacillus subtilis on avocado flowers. Scanning electron microscopy studies showed that the bacterium could attach and colonise avocado flower surfaces. It can also survive on the flowers for longer periods of time. In vivo mode of action of the antagonist against stem-end rot (SER) pathogens was also studied where results showed lysis and degradation of hyphae and conidia. However, no viable colonies were retrieved from bee antagonist dispersal under field conditions. Bee antagonist dissemination was compared with antagonist and fungicide spray applications in terms of SER control and the added effect on other diseases such as Cercospora spot and anthracnose. Spray applications of the antagonist were more effective in reducing the incidence of SER than bee dissemination. Integrated sprays of the antagonist and fungicides significantly reduced the incidence of both pre- and postharvest diseases. The identity of Dothiorella aromatica, one of the most important SER pathogens, was investigated at a molecular level. RAPD techniques using the discriminatory OPC02 primer successfully separated isolates into three groups based on banding profiles. A further study using RFLP identified the pathogen as a Botryosphaeria spp. The most dominant specie was B. parva followed by B. rhodina. Further studies should focus on assessing the distribution of these pathogens within avocado-growing regions of South Africa. / Dissertation (MSc (Plant Pathology))--University of Pretoria, 2006. / Microbiology and Plant Pathology / unrestricted

This thesis attempts to establish that Ford Madox Ford's tetralogy Parade's End is in structure and essence a comic novel. The first chapter deals briefly with the fourth novel, The Last Post. The suggestion is made that it provides a comic conclusion to the tetralogy. Its vision is positive and promises a better world for mankind. Chapter Two follows the suggestion that Parade's End is comic with a theoretical analysis of the nature and form of comedy. The theory is taken largely from Northrop Frye's work Anatomy of Criticism. The central point made is that in comic action there is a motion from one type of society to another. In the new society, which is more humane than the old, the romantic hero and heroine are finally able to achieve happiness. There is a freeing of artificial bonds imposed by the old society, which is characterized in the tetralogy by the term "parade". When the old society has finally been defeated, a comic saturnalia breaks out in A Man Could Stand Up. That Parade's End so closely follows a comic pattern suggests that Ford was using the pattern very consciously. Chapter Three deals with Ford's technique of impressionism and discusses the relation of this technique to the mode of irony as defined by Frye. Ford's ironic vision is discussed with reference to his dual view of Tietjens' character as both heroic and "villainous". "Parade" is also to be considered ironically in Ford's work. The old code has produced a system which is apparently very beautiful and very virtuous but all systems are found to be inhibiting and deleterious. Using the concept of the dual vision, the rest of the thesis discusses some of the characters in the comic action. They are seen to be suffering from a bondage to a social code which represses man's instinctual nature. The code of repression leads to comic scenes such as the one in which Duchemin disrupts the elaborate breakfast party with his obscenities. Tietjens is the main concern and he is considered as an inhibitor of festivity who gradually, through the experience of war, is born into the comic hero, breaks with society and sets out to establish a new society in the pastoral world of the fourth novel. The war itself is seen as an extension of the nature and activities of society. A society which has imprisoned intimacy, communication, sexuality, love, explodes into war because it has an inadequate vision of the necessities of human existence. The novel, Parade's End, is, in part, an argument against rigid social institutions. The comic action moves away from rigidity towards a sense of flux. The old order decays, falls, but this fall is not tragic nor epic; it is found to be salubrious and comic. Tietjens sloughs off his old skin, his old principles, and frees his instinctual nature to become more human. What was feared is not to be feared; the passing of generations is one of the things that is. The other thing that is is Tietjens' character. His system goes but he himself does not. In contrast, his brother Mark, totally identified with the system, dies. The romantic hero and heroine, however, are saved, as they always are in a world of comic fiction. / Arts, Faculty of / English, Department of / Graduate

Colorectal cancer is the second leading cause of cancer-related deaths behind lung cancer in the United States. Colonoscopy is the preferred screening method for detection of diseases like Colorectal Cancer. In the year 2006, American Society for Gastrointestinal Endoscopy (ASGE) and American College of Gastroenterology (ACG) issued guidelines for quality colonoscopy. The guidelines suggest that on average the withdrawal phase during a screening colonoscopy should last a minimum of 6 minutes. My aim is to classify the colonoscopy video into insertion and withdrawal phase. The problem is that currently existing shot detection techniques cannot be applied because colonoscopy is a single camera shot from start to end. An algorithm to detect phase boundary has already been developed by the MIGLAB team. Existing method has acceptable levels of accuracy but the main issue is dependency on MPEG (Moving Pictures Expert Group) 1/2. I implemented exhaustive search for motion estimation to reduce the execution time and improve the accuracy. I took advantages of the C/C++ programming languages with multithreading which helped us get even better performances in terms of execution time. I propose a method for improving the current method of colonoscopy video analysis and also an extension for the same to make it usable for real time videos. The real time version we implemented is capable of handling streams coming directly from the camera in the form of uncompressed bitmap frames. Existing implementation could not be applied to real time scenario because of its dependency on MPEG 1/2. Future direction of this research includes improved motion search and GPU parallel computing techniques.

Introduction: In 2010, of the 129 million visits to the emergency department (ED), 240,000 resulted in the patient dying or being pronounced dead on arrival. This number is likely to continue to increase as a significant portion of the American population ages and seeks care in the ED. Though care in the ED is focused on saving lives, death cannot always be prevented. Consequently, nurses face many barriers to providing quality end-of-life (EOL) care in the ED when death occurs. The purpose of this study was to identify suggestions emergency nurses have to improve EOL care specifically in rural ED's. Methods: A 57-item questionnaire was sent to 52 rural hospitals in the Intermountain West and Alaska. One of the 57 questions asked nurses to identify the one aspect of EOL care they would change for dying patients in the ED. Each qualitative response was individually reviewed by a research team and then coded into a theme. Results: Four major themes and three minor themes were identified. The major themes were providing greater privacy during EOL care for patients and family members, increasing availability of support services, additional staffing, and improved staff and community education. Discussion: Providing adequate privacy for patients and family members is a major barrier to providing EOL care in the ED. This is largely due to poor department design, especially in rural ED's where space is limited. Lack of support services such as religious leaders, social workers, and additional staffing are also barriers to providing quality EOL care in rural ED's. Consequently, rural nurses are commonly pulled away from EOL care to perform ancillary duties because additional support personnel are lacking. Conclusion: Providing EOL care in the ED is an extremely challenging and demanding task. It is especially difficult in rural ED's where staffing and resources are limited. Consequently, it is imperative that supportive behaviors are acknowledged and barriers are identified to improve EOL care provided to patients and family members in rural ED's. Due to the current lack of research in rural EOL care, further research is justified regarding this topic.
