The new ideal : reshaping Schererville
Schererville, Indiana could be considered a suburb of Chicago due to its proximity to major highways leading there and the number of people who live there and commute to the city. But Schererville still has an identity of its own. Nicknamed "The Crossroads of America" Schererville owns the intersections of Highways 30 and 41, once the Lincoln Highway and the Dixie Highway, the first two highways in the United States. However, the problem with starting a town around two major highways is that they divide the city into quadrants, forbidding pedestrian traffic. Schererville was built for the car. The Lincoln Highway no longer runs through the old downtown of Schererville, which has allowed some historic places to be preserved. But the downtown has no life to it, despite the recent construction of a new police station and city hall.
My architecture studio design project includes the design of a recreation center in downtown Schererville, and suggestions for urban redesign of the rest of the town, with ideas from my experiences at home and from my participation in the Polyark World Tour. Careful planning could make the whole town more pedestrian-friendly. Pride exists in the town because of "The Crossroads of the Nation" claim, but it is one of the worst places to try to travel across. By celebrating the new bike path with the new recreation center and other destinations, Schererville can have a reason to be proud of its transportation again. The historic railroad lines will be celebrated by the location of the new recreation center, and a new gateway into the town will help dissolve the barrier of the massive highways. This project reflects the needs of the community, especially the young and old who are not able to drive far away from home. The new Schererville Recreation Center is a worthwhile destination for all.Honors CollegeThesis (B.?.
Effects of Simple Postural Instructions on Running Form Modification in Recreational Runners – Preliminary Findings
Background and purpose: Running is one of the most popular exercises but it is also an activity with a high incidence of injury. Running form modification involving a forward lean of the trunk and forefoot strike pattern has been shown to be effective in attenuating the impact forces of the lower extremity. However, it is currently unknown how these changes can be most effectively instructed and learned by the runners. Previous studies have shown that practicing a motor task with an external focus can facilitate learning and retention when compared to the more common internal focus instructions. The purpose of this study is to examine the effectiveness of external and internal attentional focus cues on trunk posture and peak vertical ground reaction force (GRF) during the stance phase of running. Subjects and Methods: Ten recreational runners were selected for this study and randomly assigned tone of two groups receiving external or internal instructions designed to modify their running form. Trunk posture and GRF were obtained using a 3D motion capture system and a force plate instrumented treadmill while running at 2.5 m/s and a self-selected speed. Subjects were tested over a 5-week time period consisting of 4 sessions over a 4-week training program, followed by a final session 1 week after the training program to analyze retention of running form modification. Results: Overall there was a significant increase in trunk angle observed over time, following instruction, for both groups at speed 2.5 m/s. Running at speeds 2.5 m/s and a self-selected speed showed no statistically significant difference in increased trunk angle or GRF when comparing an internal versus external attentional focus. Conclusion: Simple postural instructions were shown to be effective for inducing greater trunk lean during running. This study found no difference in trunk angle or GRF when comparing internal and external attentional focus groups. Future studies would benefit from using clear and proper instructions that incorporate internal and external attentional focus cues with feedback to reinforce motor learning
Compositional Reasoning for Explicit Resource Management in Channel-Based Concurrency
We define a pi-calculus variant with a costed semantics where channels are
treated as resources that must explicitly be allocated before they are used and
can be deallocated when no longer required. We use a substructural type system
tracking permission transfer to construct coinductive proof techniques for
comparing behaviour and resource usage efficiency of concurrent processes. We
establish full abstraction results between our coinductive definitions and a
contextual behavioural preorder describing a notion of process efficiency
w.r.t. its management of resources. We also justify these definitions and
respective proof techniques through numerous examples and a case study
comparing two concurrent implementations of an extensible buffer.Comment: 51 pages, 7 figure
Regional Warehouse Trip Production Analysis: Chicago Metro Area
This research report provides primary research data and analysis on heavy truck trip generation and characteristics from regional
distribution centers (RDC) and similar facilities in an effort to facilitate future public policy making regarding roadway transportation needs
as well as land-use and economic development decisions. The report also provides secondary data and information on intermodal freight
transportation - its growth and its economic impacts ??? to provide a regional, national, and international context for the research.
The primary data was obtained from a field survey of 12 distribution centers of various scales (7 of them regional) in Northeast Illinois.
The 12 facilities and their supervisory personnel were visited by the research team and analyzed in depth for their general business
characteristics (e.g. type of goods, number of employees, hours of operation etc.), property characteristics (e.g. location, facility size,
ceiling height) and their truck trip productions (e.g. number of arrivals-departures, geographic distribution of inbound-outbound movement,
volume per quarter etc.).
The findings of this research project in reference to the 12 facilities indicate the uniqueness and significant complexity of the distribution
centers. There is clear evidence of an increase in size (sq. ft & ceiling) and automation (racking systems) of the newer facilities as well as
24-hour operations. The comparison of daily heavy truck movement shows significant arrival concentration between 8am-10am and 8pm-
6am. In contrast the heaviest departure activity is between 4-6pm. The majority of originating freight is from the Midwest with the
outbound distributions also being allocated regionally then nationally and internationally (minimal allocation). Another result was the
increased volume concentration in the third quarter of each year between July and September.
The above results along with the significant expansions of RDC facilities in the last few years indicate the additional need for studying the
locations of the various facilities and the heavy truck traffic volume they generate. The results should also be useful in determining the
economics benefits/costs and impacts of these facilities for purposes of making infrastructure investment, economic incentive, and land
use decisions.Illinois Center for Transportation R27-15published or submitted for publicationis peer reviewe
Hegelian Spirits in Sellarsian Bottles
Though Wilfrid Sellars portrayed himself as a latter-day Kantian, I argue
here that he was at least as much a Hegelian. Several themes Sellars shares with Hegel are investigated: the sociality and normativity of the intentional, categorial change, the rejection of the given, and especially their denial of an unknowable thing-in-itself. They are also united by an emphasis on the unity of things—the belief that things do ‘‘hang together.’’ Hegel’s unity is idealist; Sellars’ is physicalist; the differences are substantial, but so are the resonances
No evidence of bias from fish behavior in the selectivity of size and sex of the protogynous red porgy (Pagrus pagrus, Sparidae) by hook-and-line gear
Most fisheries select the size of fish to be caught (are size selective), and many factors, including gear, market
demands, species distributions, fishery laws, and the behavior of both fishermen and fish, can contribute to that selectivity. Most fishing gear is size-selective and some, such as gill nets, are more so than others. The targeting behavior of fishermen is another key reason commercial
and recreational fisheries tend to be size-selective. The more successful fishermen constantly seek areas and
methods that yield larger or more profitable sizes of fish. Fishery regulations, especially size limits, produce
size-selective harvests. Another factor with the potential to cause selectivity in a hook-and-line fishery is the different behavioral responses of fish to the bait or lure, whether the different responses arise among different fish
sizes or between the sexes
