Using Interactive 3D Software to Create Manipulatable Human Figures for Body Perception Research

The poster presents the use of the DAZ3D program as a measurement tool for body size perception. When studying body schema, researchers often rely on human figure comparisons to examine body size perceptions. Often these figures are two-dimensional drawings or photos of human bodies. However, human bodies are three-dimensional. Previous research has shown the advantage of using three-dimensional changeable figures in assessing body size perception (Crossley, Cornelissen, & Tovee, 2012). We chose the DAZ3D program over other options (e.g., Body Visualizer) because it allows the user to rotate the figure in space (both depth and plane), convert manipulated figure measures to real life metrics (e.g., inches or centimeters), input real life metrics to create figures, and manipulate over 50 parameters of measurement consisting of both length and circumference. The downside to DAZ3D is that it can be confusing to set up and use. We explain how to use DAZ3D software effectively for use in body size perception research. We had participants use the DAZ3D software to represent their own body, allowing them to manipulate 17 body measurements. Our data suggests that participants can easily use the program and accurately represent their body size (their figure was compared to real life body measurements). Additionally, because DAZ3D has the ability to manipulate almost all aspects of the human figure (including parameters such as muscle mass), researchers will be able to make a more fine-grained analysis of distortions in body perception in both men and women

THE ACME BUILDING FIRE HAZARDS ANALYSIS

This Fire Hazards Analysis (FHA) was written using modern fire protection engineering principles to characterize the Applied Chemistry Management and Enrichment (ACME) Building at the Pacific Northwest National Research Area (PNNRA) using both a prescriptive-based and performance-based analysis to ensure the building and occupants can be safe in fire conditions. Recommendations are made as part of this analysis to improve the survivability of this structure if a fire were to occur. This building was found to be compliant with the prescriptive code requirements from the 2018 International Building Code except for a few minor issues that are currently being repaired. The requirements from the international building code that were reviewed include but are not limited to the following: 1) Area and height specifications from Chapter five; 2) Fire rated construction from Chapter seven; 3) Interior finish requirements as found in Chapter eight; 4) Sprinkler and fire alarm stipulations as discussed in Chapter nine- review from the 2019 NFPA 13 for sprinkler systems and review from the 2019 NFPA 72 for fire alarms; 5) Means of egress designations as found in Chapter 10 that include but are not limited to: travel distance limitations, exit placement, emergency signage and lighting, corridor, door, and stairway sizing, and exit discharge; 6) Retroactive applicability from Chapter eleven of the 2018 International Fire Code was also reviewed. The performance analysis portion of this report involved several design basis fires. These involved gasoline and diesel pool fires, vehicle fires, and workstation fires used to estimate the time for sprinkler activation, determine the time requirements for safe egress, and the capability of the building contents to resist fire spread. The main finding was that the west high bay location used for loading shipping trailers has the potential for serious consequences for fire spread if a truck fire were to occur and combustible storage was not adequately controlled. The sixty foot high ceilings require a significant fire to trigger sprinklers and the suppression will likely not control fire growth. The results from the remainder of the design basis fires show acceptable performance for the structure and occupants in fire conditions. The ACME Building is acceptable for continued operations. With minor exceptions, it meets current code requirements. Personnel can safely egress if a worst-case fire scenario occurs. Recommendations include changes in the storage configuration in certain areas, minimization of the use of wood pallets and caution regarding the use of trucks that are parked within the facility during offloading

Social Capital in Senegal: Bane or Boom?

In Senegal, at first glance, it appears that one’s social capital allows the individual to be able to survive, but not thrive. Social capital in Senegal appears to hinder local economic development. For my Capstone, I would like to focus more on what social capital means in Senegal, looking at both the benefits and drawbacks of its’ affect on local economic development. I will be focusing my research within my site, Dahra, population 40,000, and drawing upon case studies as I begin work. I will also be looking at the role of non-governmental organizations (specifically Peace Corps) in generating social capital or acting as intermediaries (bridging social capital) between marginalized groups and local economic development

AN INTER-WATERSHED COMPARISON STUDY OF BEDROCK CONTROLS ON SHALLOW SUBSURFACE FLOW AND STREAMFLOW RESPONSE

Bedrock controls on watershed response have been actively studied in recent years, however, most conclusions are based on surface water analysis leaving unresolved questions about the nature of bedrock flow paths and ultimately their control on watershed response. In this study, we investigated bedrock controls on watershed response by simultaneously monitoring the hydrology of two adjacent watersheds underlain by dissimilar geologic formations (monzonite vs. meta-sandstone) and by characterizing subsurface conditions through bedrock drilling and fracture mapping. We hypothesized, when soils saturate, the underlying bedrock geology may influence the partitioning of shallow subsurface flow (SSF) between soil and bedrock flow paths, resulting in a divergence in hillslope runoff response between each watershed. We found SSF occurred for longer periods and at greater magnitudes in the monzonite watershed relative to the meta-sandstone watershed. Furthermore, hillslopes underlain by monzonite bedrock drained more rapidly compared to the hillslopes underlain by meta-sandstone bedrock. Paired hydrometric observations of soil and bedrock flow systems linked hillslope discharge to bedrock exfiltration at the slope base. The bedrock driven control on hillslope discharge promoted a stark divergence in the streamflow response between each watershed. These findings provide strong evidence supporting a bottom up view of watershed function, where bedrock flows systems are a fundamental control on the hydrologic response of hillslopes and stream networks. Conclusions from this study bolster the need to further investigate how differences in bedrock properties across mountainous watersheds will influence the resilience of headwater basins in the face of climate change
