Interactions Of Brown Marmorated Stink Bug, Colletotrichum Acutatum And Trap Crops In Organic Tomato Production, Robert James Voshell

Graduate Theses, Dissertations, and Problem Reports (ETD)

Colletotrichum spp. (Ascomycota) cause anthracnose of tomato fruits (Solanum lycopersicum). Halyomorpha halys, the Brown Marmorated Stink Bug (Hemiptera: Pentatomidae) is an invasive insect that injures tomato fruits with a piercing/sucking mouthpart.;To determine if H. halys feeding increases incidence of anthracnose on tomato fruit, five experiments were conducted. A 21-day transmission study was performed using detached fruits inside plastic containers in an incubator at 22°C. Tomato fruits receiving stink bugs with Colletotrichum inoculum had significantly higher anthracnose incidence than fruit receiving Colletotrichum inoculum only. A treatment using infested stink bugs (H. halys was placed in a petri dish of sporulating C. …


Tides And Air, Kristine R. Synowka Aug 2014

Tides And Air, Kristine R. Synowka

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis discusses the intermedia and sculptural artwork for Kristine R. Synowka's exhibition, Tides and Air. Through a wide variety of different media, both traditional and electronic, a hypothetical world split between terrestrial plants and weeds and ocean environments is explored within the space of the gallery. Echoing the movement of the viewer through the gallery space, the imagery switches focus from the familiar backyard plants to an oceanic realm based off the kinds of environments that we mostly know from theory. A possible new mythology relating to animals is subtly hinted at through encounters with artwork portraying animals from …


Developing An Intergroup Anxiety Toward Muslims Scale, Patricia Hopkins Aug 2014

Developing An Intergroup Anxiety Toward Muslims Scale, Patricia Hopkins

Graduate Theses, Dissertations, and Problem Reports (ETD)

Understanding intergroup relations and the anxiety that can result has become increasingly relevant to interactions between Muslim and non-Muslim individuals due to current tensions between Islamic groups and many Western nations (e.g., acts of terrorism in Madrid and London, the U.S. War on Terror). Furthermore, the anticipated increase in migration from the Middle East and North Africa to Western countries will undoubtedly lead to increased contact between Muslim and non-Muslim groups. In order to improve intergroup relations and reduce potential conflict between groups, it is important to understand factors that influence intergroup contact. One such factor is intergroup anxiety, or …


Modeling Errors In Biometric Surveillance And De-Duplication Systems, Brian Matthew Decann Aug 2014

Modeling Errors In Biometric Surveillance And De-Duplication Systems, Brian Matthew Decann

Graduate Theses, Dissertations, and Problem Reports (ETD)

In biometrics-based surveillance and de-duplication applications, the system commonly determines if a given individual has been encountered before. In this dissertation, these applications are viewed as specific instances of a broader class of problems known as Anonymous Identification. Here, the system does not necessarily determine the identity of a person; rather, it merely establishes if the given input biometric data was encountered previously. This dissertation demonstrates that traditional biometric evaluation measures cannot adequately estimate the error rate of an anonymous identification system in general and a de-duplication system in particular. In this regard, the first contribution is the design of …


Why And How Organizational Members Encourage Their Peer Coworkers To Voluntarily Exit The Organization: An Investigation Of Peer-Influence Exit Tactics, Michael Sollitto Aug 2014

Why And How Organizational Members Encourage Their Peer Coworkers To Voluntarily Exit The Organization: An Investigation Of Peer-Influence Exit Tactics, Michael Sollitto

Graduate Theses, Dissertations, and Problem Reports (ETD)

Previous scholars have found that organizational members use various tactics to encourage their peer coworkers to voluntarily exit their organizations. These tactics are known as peer-influence exit tactics. What has been missing from the literature is clarity about the factors that influence organizational members' use of peer-influence exit tactics. This dissertation explored the construct of peer-influenced exit to develop greater clarity about the motives for encouraging peer coworkers to leave, the characteristics of the peer-influence exit tactic source and receiver, and the organizational influences on peer-influenced exit. Study 1 used an open-ended survey design to explore the motives, process, and …


Psychosocial Predictors Of Breast Awareness Behaviors, Carol Goulet Aug 2014

Psychosocial Predictors Of Breast Awareness Behaviors, Carol Goulet

Graduate Theses, Dissertations, and Problem Reports (ETD)

Whether women should practice breast self-examination (BSE) has been debated for decades. Current guidelines promote understanding how one's breasts normally look and feel through the practice of BSE or informal self-examination practices (referred to as breast awareness). This study investigated how modern women practice breast awareness behaviors, and how personal, theoretical, and psychosocial constructs influence engagement in these behaviors. Data from 626 women without a history of breast cancer were used to investigate associations between psychosocial variables (e.g., anxiety, body dissatisfaction, cancer fatalism; religious beliefs and participation) and breast awareness behaviors (BSE frequency and proficiency, frequency of checking for lumps, …

Watershed - A Transdisciplinary Social Design Process Applied To An Environmental Issue, Forrest Thomas Conroy Aug 2014

Watershed - A Transdisciplinary Social Design Process Applied To An Environmental Issue, Forrest Thomas Conroy

Graduate Theses, Dissertations, and Problem Reports (ETD)

Wicked problems are often vast, complex, and difficult to navigate. Often used in dealing with social design issues, the term "wicked" is intended to connote a problem that is difficult to define and solve rather than its moral implications.1 These problems, like watershed maintenance and pollution mitigation, involve an entwined community of diverse players, intricate systems, and ever-changing terrain. Because of their pluralistic nature, these problems can seem impossible to solve and even impossible to understand. This requires a collective approach and new ways of thinking to create better understanding and solutions. Important changes occur when citizens are knowledgeable, see …


Evolutionary Search Techniques With Strong Heuristics For Multi-Objective Feature Selection In Software Product Lines, Abdel Salam Sayyad Aug 2014

Evolutionary Search Techniques With Strong Heuristics For Multi-Objective Feature Selection In Software Product Lines, Abdel Salam Sayyad

Graduate Theses, Dissertations, and Problem Reports (ETD)

Software design is a process of trading off competing objectives. If the user objective space is rich, then we should use optimizers that can fully exploit that richness. For example, this study configures software product lines (expressed as feature models) using various search-based software engineering methods. Our main result is that as we increase the number of optimization objectives, the methods in widespread use (e.g. NSGA-II, SPEA2) perform much worse than IBEA (Indicator-Based Evolutionary Algorithm). IBEA works best since it makes most use of user preference knowledge. Hence it does better on the standard measures (hypervolume and spread) but it …


Effects Of Dietary Immunomodulation On Parasite Load In Commercial Crossbred Lambs, Rebecca Christine Price Aug 2014

Effects Of Dietary Immunomodulation On Parasite Load In Commercial Crossbred Lambs, Rebecca Christine Price

Graduate Theses, Dissertations, and Problem Reports (ETD)

Multidrug resistant gastrointestinal nematodes have left sheep producers with little options to control the detrimental effects of parasitism on their flocks. Immunomodulation has been used in many autoimmune diseases in an effort to downregulate the immune system and alleviate pathology. However, upregulation of immune responses by use of dietary immunosaccharides may allow parasite susceptible sheep to clear a Haemonchus contortus infection. To test this hypothesis, Dorset-Texel lambs were fed a ration including CelmanaxRTM at 1g/hd/day for one week prior to receiving an experimental infection of 10,000 L3 stage H. contortus larvae; which continued until the completion of the study. Increases …

A Supervised Low-Rank Matrix Decomposition For Matching, Sajid Sharlemin Aug 2014

A Supervised Low-Rank Matrix Decomposition For Matching, Sajid Sharlemin

Graduate Theses, Dissertations, and Problem Reports (ETD)

Human identification from images captured in unconstrained scenarios is still an unsolved problem, which finds applications in several areas, ranging from all the settings typical of video surveillance, to robotics, metadata enrichment of social media content, and mobile applications. The most recent approaches rely on techniques such as sparse coding and low-rank matrix decomposition. Those build a generative representation of the data that on the one hand, attempts capturing all the information descriptive of an identity; on the other hand, training and testing are complex to allow those algorithms to be robust against grossly corrupted data, which are typical of …


Belarus's National Narratives And Representation Of The Grand Duchy Of Lithuania, Jevgenijs Rjascenko Aug 2014

Belarus's National Narratives And Representation Of The Grand Duchy Of Lithuania, Jevgenijs Rjascenko

Graduate Theses, Dissertations, and Problem Reports (ETD)

In its theoretical framework this thesis relies on the discussion of the existing approaches towards the study of nationalism such as the perennialist, the modernist/constructivist and the ethno-symbolist. The ethno-symbolist approach by Anthony D. Smith, however, is chosen as the most appropriate for examining Belarus's nation-building process and therefore, its ability to explain different expressions of Belarus's national narratives is emphasized. The empirical discussion of Belarus's post-independence nation-building process explains the peculiarity of the Belarusian case in which the official national narrative coexists with the alternative national narrative in Belarus's public sphere. The research question, however, is centered on the …


Bubble Size Effects In Coal Flotation And Phosphate Reverse Flotation Using A Pico-Nano Bubble Generator, Yu Xiong Aug 2014

Bubble Size Effects In Coal Flotation And Phosphate Reverse Flotation Using A Pico-Nano Bubble Generator, Yu Xiong

Graduate Theses, Dissertations, and Problem Reports (ETD)

Froth flotation is widely used in minerals industry. However, it is effective in a narrow size range, nominally 45--250 mum for coal and 10--150 mum for minerals. And the flotation performance of coal and minerals beyond this size range is not quite satisfactory. It is now recognized that the low-flotation efficiency of ultrafine particles is mainly due to the low probability of bubble-particle collision while the main reason for poor flotation recovery of coarse particles is the high probability of detachment of particles from the bubble surface.;Pico-nano bubbles refer to tiny bubbles smaller than 0.5 mum, which can be produced …

Graduate Theses, Dissertations, and Problem Reports (ETD)

A new Multi Agent System (MAS) design for fault location, isolation and restoration in power distribution systems is presented. In proposed approach, when there is a fault in the Power Distribution System (PDS), MAS quickly isolates the fault and restores the service to fault-free zones. Hierarchical coordination strategy is introduced to manage the agents which integrate the advantages of both centralized and decentralized coordination strategies. In this framework, Zone Agent (ZA) locate and isolate the fault based on the locally available information and assist the Feeder Agent (FA) for reconfiguration and restoration. FA can solve the restoration problem using the …


Fully Coupled Finite Element Model To Study Multiple Hydraulic Fracturing In Heterogeneous Tight Formations, Ruizhi Zhong Aug 2014

Fully Coupled Finite Element Model To Study Multiple Hydraulic Fracturing In Heterogeneous Tight Formations, Ruizhi Zhong

Graduate Theses, Dissertations, and Problem Reports (ETD)

Hydraulic fracturing is a widely used technique in industry to enhance oil and gas recovery. The process involves the injection of fracking fluid with high pressure into the wellbore to propagate initial fractures generated during well perforation. It is a coupled process of fluid and rock mechanics one controlling the fluid movement and other fracture propagation. There is a lack of reliable and robust simulation technique that can couple these two processes at the same time being practical for large domain size of hydraulic fracturing in the field scale. In hydraulic fracturing, multiple fractures are also created within one cluster …

Nerve Growth Factor Regulates Na+ Transport In Human Airway Epithelial Cells, Michael J. Shimko Aug 2014

Nerve Growth Factor Regulates Na+ Transport In Human Airway Epithelial Cells, Michael J. Shimko

Graduate Theses, Dissertations, and Problem Reports (ETD)

Nerve growth factor (NGF) was discovered for its ability to enhance nerve growth, but recent evidence suggests there is a correlation between elevated NGF levels in the lung and airway diseases, including lung inflammatory diseases and respiratory virus infections. NGF can be produced and act upon both structural and non-structural cells of the airways, and overexpression of NGF causes morphological and physiological changes in the airways, such as an increased innervation resulting in a neuronal remodeling of the lung, airway smooth muscle thickening, increased vascularization, airway hyperreactivity to capsaicin, and subepithelial thickening. Although work has been conducted to investigate NGFs …

Explicit Disclosure In Retail Communication: Impact Of Undetermined Social Network Site Relationships On Branded Identity, Hannah R. Gnegy Aug 2014

Explicit Disclosure In Retail Communication: Impact Of Undetermined Social Network Site Relationships On Branded Identity, Hannah R. Gnegy

Graduate Theses, Dissertations, and Problem Reports (ETD)

One of the most impactful technologies to emerge from Web 2.0 developments has been the social network site. In traditional models of branded identity, it is assumed that there is a distinction made between the retailer and consumer (de Chernatony, 1999; Kapferer, 2008). However, social network sites allow for the formation of undetermined relationships in which the underlying role of a party may be unknown.;As social network sites continue to shape retail practices, a gap in knowledge exists regarding how models of branded identity need to be modified to meet the demands of these undetermined social network site relationships. Through …
