This project focuses on the fringe of Garfield Park – the belt where neighborhood transitions to park – and reimagines how these spaces can benefit both the private and public realms as they form stronger partnerships in the future. It endeavors to establish desired future design characteristics, aesthetic characteristics, spatial patterns and dimensions for a re-designed community/park interface as well as preferred activities and program elements that can mutually benefit and synergistically enhance the performance and purposes of the adjacent community and the park facility.
Garfield Park has enormous potential for becoming an alternative recreation/leisure destination on par with the Canal Walk, White River State Park, and the Indianapolis Cultural Trail in downtown Indianapolis. In particular, the fringe area can serve to give cu...

Family presence during resuscitation (FPDR) has been a controversial issue worldwide over the past two decades. Health care institutions have differing practices regarding FPDR. Health care team members are often not in consensus about FPDR. Research has not yet clarified the perceptions of nurses from diverse geographic areas regarding FPDR. This study proposed to expand what was known about nurses’ perceptions of risks and benefits regarding families being present during resuscitation efforts. This study took place in one large health care system in one Midwestern state. It was a partial replication of Twibell et al.’s (2008) study. The framework for the study was the Resiliency Model of Family, Stress, Adjustment, and Adaptation (McCubbin & McCubbin, 1996). The convenience sample for this correlational study was 300 registered nurse...
In a 28-day dietary study, Lumbricus terrestris were placed in one quart containers with soil and offered either corn (Zea mays L.), soybean (Glycine max L. Merr.) or alfalfa (Medicago sativa) leaves, corn leaves treated with a 1:1 solution of 28% N fertilizer and deionized water, corn or soybean stalks, or no addition. The worms were weighed initially and after 28 days to determine biomass production, which was used for determining food quality. Worms exhibited large weight gains when fed alfalfa or soybean leaves, intermediate weight gains when fed corn leaves treated with N, and little or no gains for the remainder of treatments. N content of the tissues was positively correlated to biomass production. These results support the hypothesis that earthworm growth is determined by food quality, particularly N content.
Biological soil inoculants are products that contain beneficial microorganisms with the ability to increase plant-available nutrients. Soil inoculants are claimed to serve as a supplement for fertilizer N, improve germination and tilth, improve root systems, and increase crop quality and yield. The inoculant evaluated in this study was Effective Microorganisms (EM) produced by Nature Farm Foundation of Lompoc, California. A field trial with corn (Zea mays, L.) was conducted at Oakwood Organic Farm in East Central Indiana in 1992. Two soil types were used in the study, a Genesee silt loam (Fluventic Eutorchrept) and a Sloan silt loam (Fluventic Haplaquoll). Soil nitrate level measured through the growing season was not significantly affected by the addition of EM. Neither foliar nutrient content nor grain dry matter yield were significa...
Rivers and streams around the world are increasingly polluted by pharmaceuticals and
personal care products (PPCPs). In order to understand what the effects on freshwater systems
are, it is necessary to combine laboratory testing of water samples in conjunction with
biomonitoring. The Asiatic clam, Corbicula fluminea, is an ideal species for biomonitoring since
they accumulate toxins within their tissues. In 2011 and 2012, C. fluminea were systematically
sampled across nine sites in 2011 and nineteen sites in 2012; water samples were collected and
subsequently analyzed for pharmaceuticals. Principal component analysis, Canonical
Correspondence Analysis, and univariate linear regressions were used to analyze the results from
both sampling years. Results from the Principal Component Analysis showed Corbicula
fluminea density and...
Depth to water table in soils influences soil properties such as color and horizon thickness and, in some cases, determines soil classification under Soil Taxonomy. The objective of this study was to determine the depth to water table in three Indiana soil series and to evaluate the effect of soil series and landscape on water table levels. The three soils studied were moderately well drained Glynwood, somewhat poorly drained Blount, and poorly drained Pewamo soil series. The effect of soil horizon on water table levels was also examined.Data were collected from 3/21/94 to 6/6/94 at the Hults Environmental Learning Center in Albany, Indiana. The effect of soil type on water table levels was observed as measurable differences in drainage characteristics in the three soil series. Soil horizon had limited effect on water table fluctuation...
