The parallel programming of landing position in saccadic eye movement sequences

Saccadic eye movements occur in sequences, gathering new information about the visual environment to support successful task completion. Here we examine the control of these saccadic sequences and specifically the extent to which the spatial aspects of the saccadic responses are programmed in parallel. We asked participants to saccade to a series of visual targets and, while they shifted their gaze around the display, we displaced select targets. We found that saccade landing position was deviated towards the previous location of the target suggesting that partial parallel programming of target location information was occurring. The saccade landing position was also affected by the new target location which demonstrates that the saccade landing position was also partially updated following the shift. This pattern was present even for targets that were the subject of the next fixation. Having a greater preview about the sequence path influenced saccade accuracy with saccades being less affected by relocations when there is less preview information. The results demonstrate that landing positions from a saccade sequence are programmed in parallel and combined with more immediate visual signals

Alfred D. Gilchrist Architectural Drawings - Accession 1103

The collection consists of architectural drawings and other related items of Alfred D. Gilchrist (1873-1944). Gilchrist predominately operated in South Carolina and North Carolina from 1913 to 1940. He started working in Rock Hill, SC as the manager of the Rock Hill office of Hook and Rogers, Architects in 1913 and by 1920, he opened his own office in Rock Hill which he maintained through 1940. The drawings consist of homes, public buildings (i.e. schools, city government buildings, etc.), and private businesses that were mainly located in York County (SC) and Chester County (SC). Some of Mr. Gilchrist’s architectural drawings were done in other cities/locations including: Blackstock, (SC), Darlington (SC), Dillon (SC), Gaffney (SC), Kershaw (SC), Lancaster (SC), Liberty Hill (SC), Mullins (SC), Morganton (NC), Shelby (NC), Winnsboro (SC), Winston-Salem (NC).https://digitalcommons.winthrop.edu/manuscriptcollection_findingaids/2277/thumbnail.jp

The unsteady flow of a weakly compressible fluid in a thin porous layer. I: Two-dimensional theory

We consider the problem of determining the pressure and velocity fields for a weakly compressible fluid flowing in a two-dimensional reservoir in an inhomogeneous, anisotropic porous medium, with vertical side walls and variable upper and lower boundaries, in the presence of vertical wells injecting or extracting fluid. Numerical solution of this problem may be expensive, particularly in the case that the depth scale of the layer h is small compared to the horizontal length scale l. This is a situation which occurs frequently in the application to oil reservoir recovery. Under the assumption that epsilon=h/l<<1, we show that the pressure field varies only in the horizontal direction away from the wells (the outer region). We construct two-term asymptotic expansions in epsilon in both the inner (near the wells) and outer regions and use the asymptotic matching principle to derive analytical expressions for all significant process quantities. This approach, via the method of matched asymptotic expansions, takes advantage of the small aspect ratio of the reservoir, epsilon, at precisely the stage where full numerical computations become stiff, and also reveals the detailed structure of the dynamics of the flow, both in the neighborhood of wells and away from wells

Tobacco Use During and After Pregnancy: The Smoking Behaviors of African American Women and Their Attempts to Quit

Minorities suffer disproportionately from tobacco smoke-related morbidity and mortality nationwide. Tobacco-related illnesses are responsible for approximately 47,000 deaths of African Americans annually. Furthermore, greater tobacco- related health disparities exist among African American women in the state of Pennsylvania and the city of Pittsburgh; as the local and state maternal smoke rates exceed the national average. Additionally, low birth weight and infant mortality rates linked to maternal smoking has been disproportionately elevated among African American women in this geographical area. African American mothers who quit smoking generally have higher relapse rates than their Caucasian counterparts. Research limitations in understanding the smoking cessation, self- quitting and relapse prevention among African American women particularly in Pittsburgh, PA; serves as a foundation for this study. Thus, two focus groups were conducted with a sample of 13 African American maternal smokers in the Pittsburgh area to assess their smoking and quitting experiences as well as their unmet needs for cessation treatment. A brief survey was administered to ascertain the participants' socio demographic characteristics. The data collected mirror previous research as nicotine addiction, stress and poor social surroundings act as barriers to successful quitting. The women identified willpower as the key to permanent smoking cessation but lack the self-efficacy to quit. Recommendations for advanced investigations and cessation programs for this population are provided. The findings from this exploratory study are significant to public health research as they provide a guide for future research and offer valuable insight for modifying and creating effective smoking cessation interventions for African American women; which can produce long term effects by decreasing the maternal smoking rate disparity in Pittsburgh, Pennsylvania
