Beyond a Front Desk: The Residential Hotel as Home

This report is based on a comprehensive analysis of Winnipeg’s single room occupancy hotels. In developing and writing the report, an emphasis was placed on ensuring that the voices of SRO residents were heard and that they would identify and characterize their own realties. This was accomplished in a number of ways. First, a case study of Winnipeg hotels was undertaken, with field research including not only surveys, but also building trust among local residents. During the course of this fieldwork, researchers were able to become comfortable with the area and its people, while also developing a sense of the issues affecting hotel residents, owners and the surrounding community. Observations were drawn from a diverse set of downtown hotels that encompassed a region stretching from Broadway Boulevard on the south to Selkirk Avenue on the north. In total, eighty-one surveys were completed in nearly fifteen hotels, offering broad and contrasting perspectives on life in an SRO. The research was approached from three perspectives - the people who live in their rooms, the physical characteristics of the hotels (the bars, restaurants and common spaces), and the surrounding community. The goal was to determine whether SROs are an important form of affordable shelter. It was also our intent to determine whether practical solutions exist that could contribute to creating the best possible accommodation in an affordable and healthful manner

Fuel Loads, Fire Severity, and Tree Mortality in Florida Keys Pine Forests

In fire dependent forested ecosystems, fire managers are greatly interested in predicting the consequences of their management-oriented prescribed burnings on post-fire tree mortality. While fire intensity is believed to be a strong predictor of tree mortality, fire behavior itself largely depends on fuel characteristics, including both their structure and spatial distribution. We examined the type and distribution of fuels, their effects on fire behavior, and the effects of fire on tree mortality in slash pine forests in the Florida Keys. We conducted a burning experiment in six blocks, and burned eleven plots, three in winter and eight in summer, over a four-year period from 1998 to 2001. Post-fire slash pine mortality was investigated annually for one, two or three years in seven burn plots, three winter burn and four summer burn plots. We used linear regression to model the effects of fuel types on fire severity, and logistic regression to model the effects of burn season, fire severity and tree dimensions on tree mortality. Fire severity increased with surface fuel loads, but was negatively related to the quantity of hardwood shrub fuels. Tree mortality was significantly higher in summer burn than in winter burn plots, and was strongly related to tree size and crown scorch percent. This study suggests that pine tree mortality can be minimized by burning in winter. However, in pine forests where the burning objective is to suppress the growth of hardwoods, winter burning involves a trade-off, in that hardwood shrub fuel consumption is reduced

Test-Retest Reliability of the Repetitive Step Test in Community Dwelling Older Adults

Each year one in every three adults over the age of 65 experience a fall resulting in serious injury and in some instances death. In this population, falling injuries are the leading cause of death and are associated with the greatest number of nonfatal injuries and trauma hospital admissions. Since balance and muscle performance decreases as one ages, it is vitally important to assess these factors as part of a comprehensive strategy to monitor and predict fall risk. Previous data analysis of the Repetitive Step Test (RST) has shown that there is a significant performance difference between non-fallers and recurrent fallers in particular stepping conditions, and that significant inter-limb differences exist in non-fallers.https://ecommons.udayton.edu/dpt_symposium/1033/thumbnail.jp

Experimental Investigation on the Wave Rotor Constant Volume Combustor

A wave rotor constant volume combustor was designed and built as a collaborative work of Rolls-Royce, Indiana University-Purdue University Indianapolis (IUPUI), and Purdue University. The experiment was designed to operate at rotational speeds of up to 4,200 rpm with air mass flow rates of approximately 18 lbm per second. Initial tests were conducted at 2,100 rpm with ethylene as fuel. The rig was operated with different fuel injection schemes to investigate operational characteristics of the combustor. Successful combustion and pressure gain were achieved over a range of operating conditions

Substrate specificity analysis of protein kinase complex Dbf2-Mob1 by peptide library and proteome array screening

BACKGROUND: The mitotic exit network (MEN) is a group of proteins that form a signaling cascade that is essential for cells to exit mitosis in Saccharomyces cerevisiae. The MEN has also been implicated in playing a role in cytokinesis. Two components of this signaling pathway are the protein kinase Dbf2 and its binding partner essential for its kinase activity, Mob1. The components of MEN that act upstream of Dbf2-Mob1 have been characterized, but physiological substrates for Dbf2-Mob1 have yet to be identified. RESULTS: Using a combination of peptide library selection, phosphorylation of opitmal peptide variants, and screening of a phosphosite array, we found that Dbf2-Mob1 preferentially phosphorylated serine over threonine and required an arginine three residues upstream of the phosphorylated serine in its substrate. This requirement for arginine in peptide substrates could not be substituted with the similarly charged lysine. This specificity determined for peptide substrates was also evident in many of the proteins phosphorylated by Dbf2-Mob1 in a proteome chip analysis. CONCLUSION: We have determined by peptide library selection and phosphosite array screening that the protein kinase Dbf2-Mob1 preferentially phosphorylated substrates that contain an RXXS motif. A subsequent proteome microarray screen revealed proteins that can be phosphorylated by Dbf2-Mob1 in vitro. These proteins are enriched for RXXS motifs, and may include substrates that mediate the function of Dbf2-Mob1 in mitotic exit and cytokinesis. The relatively low degree of sequence restriction at the site of phosphorylation suggests that Dbf2 achieves specificity by docking its substrates at a site that is distinct from the phosphorylation sit

Effect of Hydrologic Restoration on the Habitat of the Cape Sable Seaside Sparrow, 2008 – Final Report

This document summarizes the activities that were accomplished in 2008, the sixth year of the research project “Effect of hydrologic restoration on the habitat of the Cape Sable seaside sparrow”, a collaborative effort among the US Army Corps of Engineers, Everglades National Park, Florida International University, and the US Geological Survey (Florida Integrated Science Center). The major activities in 2008 included field work, data analysis, and presentations. Jay Sah presented the results of 6th year field work at the Cape Sable seaside sparrow (CSSS) Fire Meeting 2008, held on December 2-3 at the Krome Center, Homestead, Florida. In the same meeting, Mike Ross presented results from a related USFWS-funded project on encroachment pattern of woody plants in Cape Sable seaside sparrow habitat
