Nervous Conditions

Dimensions: 30 inches wide, 36 inches tallInkjet on matte paper, printed on both sidesWork displayed here as a diptych Artist\u27s narrative: Letter 174 is addressed to Paul Laurence Dunbar sent from his dear family friend H.A. Tobey. Toward the end of his life, Dunbar struggled to cope with his tuberculosis and turned to alcohol to ease his pain. As his condition worsened, Tobey began to worry about him and wrote him this moving letter of optimism expressing his sympathy regarding Paul living with a painful and deadly disease. The mirroring is showing the side effects of the disease and complications it causes to the spine and nervous system. Having the visual spread outward all throughout the page and enclosing the type further conveys how tuberculosis was taking over his body. Watercolor combined with digital illustrations created an overall feeling of being nervous and desolate — similar to the emotions of Dunbar in 1902 battling tuberculosis. The poster sheds light on the physical and mental struggles Dunbar faced in his medical condition. It shows the undeniable past experiences that have led up to this feeling of distress. The time period in which Dunbar lived and the tone of the letter’s message influenced the type palette choices of an old face and humanistic lineale. Dupincel (oldface) was designed by Rodrigo Saiani; Laca (humanistic lineal) was designed by Joana Correia.https://ecommons.udayton.edu/stu_vad_dunbarletters/1011/thumbnail.jp

Bedding control on landslides: A methodological approach for computer-aided mapping analysis

Litho-structural control on the spatial and temporal evolution of landslides is one of the major typical aspects on slopes constituted of structurally complex sequences. Mainly focused on instabilities of the earth flow type, a semi-quantitative analysis has been developed with the purpose of identifying and characterizing litho-structural control exerted by bedding on slopes and its effects on landsliding. In quantitative terms, a technique for azimuth data interpolation, Non-continuous Azimuth Distribution Methodological Approach (NADIA), is presented by means of a GIS software application. In addition, processed by NADIA, two indexes have been determined: (i) Δ, aimed at defining the relationship between the orientation of geological bedding planes and slope aspect, and (ii) C, which recognizes localized slope sectors in which the stony component of structurally complex formations is abundant and therefore operates an evolutive control of landslide masses. Furthermore, some Litho-Structural Models (LSMs) of slopes are proposed aiming at characterizing recurrent forms of structural control in the source, channel and deposition areas of gravitational movements. In order to elaborate evolutive models controlling landslide scenarios, LSMs were qualitatively related and compared with Δ and C; quantitative indexes. The methodological procedure has been applied to a lithostructurally complex area of Southern Italy where data about azimuth measurements and landslide mapping were known. It was found that the proposed methodology enables the recognition of typical control conditions on landslides in relation to the LSMs. Different control patterns on landslide shape and on style and distribution of the activity resulted for each LSM. This provides the possibility for first-order identification to be made of the spatial evolution of landslide bodies. © Author(s) 2011

Categorization and experimental evaluation of anchorage systems for fiber-reinforced polymer laminates bonded to reinforced concrete structures

While externally-bonded fiber-reinforced polymer (FRP) composites are commonly used for the strengthening of structurally deficient reinforced concrete (RC) members, the topic of anchoring FRP to concrete to achieve higher design strengths has not been addressed. Many innovative systems have been developed to anchor FRP to concrete, but the research involving these anchorage systems is not centralized and is therefore difficult to access. Additionally, systematic testing procedures for evaluating the strength of an anchorage system have not been widely used. To aid in the organization of anchorage system research and facilitate a better understanding of anchorage system behavior, a categorization system was developed based on the understood behavior of the FRP anchorage systems, as well as their potential applications. This new categorization system was used to discuss the applicability of anchorage testing procedures to various types of anchorage. Experimental research involving anchorage systems used for the emergency repair of severely damaged bridge columns was also performed. The anchorage systems included a novel anchorage system that was the focus of the experimental portion of this research. Results from the experimental program show that while the novel anchorage has promise for use in FRP strengthening applications, the assumed behavior of the novel anchorage was inconsistent with the observed behavior. Because detailed design procedures could not be developed using the experimental data, future testing of this anchorage system should be performed in the absence of the large number of variables that affected the anchorage\u27s performance during the column tests --Abstract, page iii

Mothers' conversational patterns: a comparison between typically developing children and young children with autism spectrum disorders

University of Missouri-Columbia 2013.Dissertations, Academic -- University of Missouri--Columbia -- communication science & disorders."May 2013"Autism Spectrum Disorders (ASD) are a group of developmental disabilities that cause mild to severe deficits in language, verbal and nonverbal communication, and social skills (Individuals With Disabilities Education Act, 2004). Given the social nature of conversation and the deficits in social skills seen in ASD, one might expect the development of conversation to be more delayed than other language deficits. Previous research on typically developing children has shown that differences in maternal utterances and conversational structure alter the nature of interactions in ways that appear to affect children's acquisition of language. The present study investigates the maternal pragmatic and conversational input to children with ASD, particularly the types of utterances (i.e., questions and commands) and the conversational structure produced. The children's responses to the mothers' questions and commands were also examined. Mothers of children with ASD produced significantly more commands than mothers of typically developing children matched by age or language level. The structure of mothers' conversational input also varied by group: mothers of children with ASD produced significantly more topic continuations than mothers of age-matched children. The results contribute to our knowledge of maternal language input to children with ASD

Seismic refraction methodology for groundwater level determination: "Water seismic index"

Recently, there has been increased interest in the use of refraction seismic data for the exploration and development of hydrological reservoirs. The aim of this study is to provide a procedure in order to identify groundwater levels by means of seismic refraction profiles. Assuming that the velocity of shear waves increases much less than the velocity of compressional waves in a saturated soil, seismic refraction surveys were performed for the determination of the water table. In order to have a perfect overlay of the tomography 2D grids, P and S wave seismic profiles were obtained with the same geometrical configuration. Based on the propagation of the P and S waves in the unsaturated and saturated media, a "Water Seismic Index" (WSI) was defined. WSI is related to the local variations of the P and S wave velocities and, in theoretical terms, it is correlated to groundwater level. Preliminary results indicate that there is a good agreement between the depth of the ground water and the WSI parameter. © 2009 Elsevier B.V. All rights reserved

Developing Device-Equivalent and Effective Measures of Complex Thinking with an Information Processing Framework and Mobile First Design Principles

Organizations are increasingly offering pre-employment assessments on mobile devices to evaluate candidates. The aim of this study is to investigate whether employing a mobile first responsive web design based on an information processing framework will result in device-equivalent measures of cognitive ability. Tests of numerical and deductive reasoning composed of interactive item types were tested for measurement equivalence across device types. Hypotheses were tested using data collected from paid participants over 3 weeks in 2018. Participants completed the test on both a PC and a mobile device. Paired samples t-tests indicated no mean differences in scores or number of items completed across device type. Additional analyses indicated that these item types demonstrated configural invariance and at least partial metric and scalar invariance across device types. The results of this study provide strong support that mobile first design can yield a valid and reliable test that can be used on any device and for any job level
