Acre Plan outreach and education project

Lowell, MA is currently implementing an urban renewal project in the Acre neighborhood of the city. Commonly known as the Acre Plan, this 20-year project was created with input from residents and others in the city, as required by the terms of the Urban Renewal laws that also give the City broad power to implement change, including the power of eminent domain. This residential input will continue. Due to the transient nature of the Acre community, there is a constant risk of losing continuous representation as well as having representation that is undereducated about the intentions and problems of the Plan. The purpose of this project is to create a structure to continually educate groups of residents, and enable them to meaningfully negotiate with city officials during the full implementation period of the Plan. Since the beginning of this project, a group of residents has met regularly, familiarized themselves with the Plan, received training in areas they felt were necessary, and engaged in successful negotiation with city officials on issues important to area residents.

The Significance of Error Type in Text-Based Person Perception

Previous research has suggested that errors of spelling can somewhat negatively impact reader perceptions of an author\u27s writing and cognitive abilities (e.g., Kreiner, Schnakenberg, Green, Costello, & McClin 2002; Harden, Johnson, West, & Lancaster 2009). Past research, however, has not take into account the differences inherent in certain error types. The current research sought to extend upon previous findings with the inclusion of a new error type. The new error type is referred to as an error of orthography, and is operationally defined as an error of spelling that might impact the context of the sentence to which it belongs (e.g., “which” versus “witch”)

Direct and Semidirect Products of Semigroups

The purpose of this thesis is to exhibit the direct products and the semidirect products of semigroups of orders two, three, and four. Section I consists of the definitions necessary for the proofs and computations which appear in the first five sections. In Section 2 theorems on direct products of semigroups of any order are proved. A method of writing by inspection the multiplication table of the direct product of two finite semigroups is presented in Section 3. Section 4 consists of tables listing the direct products of semigroups of order two with semigroups of orders two, three and four and a table listing the direct products of semigroups of order three with semigroups of order three. In Section 5 is considered the problem of describing the multiplication table of the direct product of two semigroups S and T by adjoining rows and columns to the multiplication table of the direct products of subsemigroups contained in S and T respectively. The direct products of those third and fourth order semigroups which are not so described are listed in Section 5. In Section 6, semidirect products of semigroups are defined, some theorems concerning them are proved, and examples are cited to show that some of the theorems on direct products are not necessarily true for semidirect products. A method of writing by inspection the multiplication table of the semidirect product of a finite semigroup and the semigroup of its endomorphisms is exhibited in Section 7. The endomorphisms of the semigroups of orders two and three, the automorphisms of the semigroups of order four, and the semidirect products of orders two, three, and four are listed in Section 8

Elucidation Of Key Interactions Between In Situ Chemical Oxidation Reagents And Soil Systems

Many soil and aquifer systems in the United States have been subjected to chemical contamination from past industrial and military activities. While many remediation technologies are currently being applied, in situ chemical oxidation (ISCO) is one option that is often favored because of its potential for fast remediation times and high user control. This technology involves the direct injection of chemical oxidizers (e.g. hydrogen peroxide, ozone, or permanganate) into targeted contaminant zones within the subsurface, and it has been proven to be amenable to both BTEX compounds and other volatile organic compounds such as chlorinated solvents. This study had several key objectives. Firstly, multiple soil samples, each containing an elevated level of a targeted chemical constituent, were successfully collected in order to provide a wide range of soil types in order to make important comparisons and correlations related to ISCO?s impacts. Secondly, the impact of common soil constituents on process reagent transport was studied in order to determine which soil constituents would act as primary hindrances for the transport of hydrogen peroxide and ozone into the subsurface. Thirdly, experiments were performed to pinpoint certain personnel safety threats such as excess oxygen and heat generation that might arise during process application. Fourthly, the impact of ISCO process application on soil fabric properties was examined. Soil aerobic microbial populations, soil hydraulic conductivity, soil natural organic matter constituents, and soil adsorptive properties were all shown to be impacted following the application of chemical oxidizers

Flight Deck Interval Management Avionics: Eye-Tracking Analysis

Interval Management (IM) is one NexGen method for achieving airspace efficiencies. In order to initiate IM procedures, Air Traffic Control provides an IM clearance to the IM aircraft's pilots that indicates an intended spacing from another aircraft (the target to follow - or TTF) and the point at which this should be achieved. Pilots enter the clearance in the flight deck IM (FIM) system; and once the TTF's Automatic Dependent Surveillance-Broadcast signal is available, the FIM algorithm generates target speeds to meet that IM goal. This study examined four Avionics Conditions (defined by the instrumentation and location presenting FIM information) and three Notification Methods (defined by the visual and aural alerts that notified pilots to IM-related events). Current commercial pilots flew descents into Dallas/Fort-Worth in a high-fidelity commercial flight deck simulation environment with realistic traffic and communications. All 12 crews experienced each Avionics Condition, where order was counterbalanced over crews. Each crew used only one of the three Notification Methods. This paper presents results from eye tracking data collected from both pilots, including: normalized number of samples falling within FIM displays, normalized heads-up time, noticing time, dwell time on first FIM display look after a new speed, a workload-related metric, and a measure comparing the scan paths of pilot flying and pilot monitoring; and discusses these in the context of other objective (vertical and speed profile deviations, response time to dial in commanded speeds, out-of-speed-conformance and reminder indications) and subjective measures (workload, situation awareness, usability, and operational acceptability)

Piezoelectric fiber mats containing polar rod-shaped pigment particles

We demonstrate converse piezoelectric behavior of electrospun polylactic acid (PLA) fiber mats containing anisometric pigment nanoparticles (Novoperm Carmine HF3C). The effective piezoelectric constant of the fiber mats was estimated to be 2 nm V-1. These findings suggest polarity of the pigment particles obtained by a milling process. Transient electric current measurements were conducted to test the residual polarization of the particles. Piezoelectric fiber mats may be utilized to make colorful electro-active fiber mats and wearable smart clothing

Three-Phase Intersection Points in Monolayers

Some phospholipid/dihydrocholesterol Langmuir monolayers form coexisting liquid phases. Gas domains form at the interface between the phospholipid-rich and dihydrocholesterol-rich liquid phases when these monolayers undergo expansion to low surface pressure. Analysis of the domain shapes thus formed yields the relative line tensions of the gas/phospholipid, gas/dihydrocholesterol, and phospholipid/dihydrocholesterol phase interfaces

The Business Value of Knowledge Management

Knowledge has been recognized as a critical competitive asset and research about knowledge management (KM) has received increasing attention. However, knowledge has also been viewed not only as an asset, but as a process that includes acquiring, organizing, and communicating the knowledge of organizational members. Additionally, organizational culture has been shown to influence the behaviors central to knowledge creation and transfer, and therefore it is proposed that these two contextual factors will have a positive relationship to business value. Using a survey of IT executives, this study empirically tests these relationships and shows a significant relationship exists between KM process implementation and business value as well as between organizational culture and business value. Practical and research implications are discussed

Beyond Evaluation: Using the RE-AIM Framework for Program Planning in Extension

Extension professionals need to apply sound frameworks to program planning and evaluation in order to demonstrate strong population health impact and value. Pragmatic application of the RE-AIM (reach, effectiveness, adoption, implementation, maintenance) framework addresses the who, what, when, where, how, and why of a program\u27s implementation. This article suggests pragmatic questions and example applications for each of the RE-AIM dimensions specifically for Extension professionals. This adapted RE-AIM tool can help Extension practitioners in all disciplines better plan and evaluate their programs and demonstrate the public value of Extension
