Providing decision support for the condition-based maintenance of circuit breakers through data mining of trip coil current signatures
The focus of this paper centers on the condition assessment of 11kV-33kV distribution circuit breakers from the analysis of their trip coil current signatures captured using an innovative condition monitoring technology developed by others. Using available expert knowledge in conjunction with a structured process of data mining, thresholds associated with features representing each stage of a circuit breaker's operation may be defined and used to characterize varying states of circuit breaker condition. Knowledge and understanding of satisfactory and unsatisfactory breaker condition can be gained and made explicit from the analysis of captured trip signature data and subsequently used to form the basis of condition assessment and diagnostic rules implemented in a decision support system, used to inform condition-based decisions affecting circuit breaker maintenance. This paper proposes a data mining method for the analysis of condition monitoring data, and demonstrates this method in its discovery of useful knowledge from trip coil data captured from a population of SP Power System's in-service circuit breakers. This knowledge then forms the basis of a decision support system for the condition assessment of these circuit breakers during routine trip testing
An Investigation of the Mentor-Protege Component of an Effective Teacher Induction Program
The purpose of this study was to identify common elements in the mentor-protege component of Illinois\u27 downstate school districts which have an enrollment between 2,000 and 6,000 students. One hundred individual schools were selected for the study. Individual schools were selected in order to assure a valid representation of grade levels and geographic locations. This study also identified those segments that, according to administrators, mentors, and beginning teachers, were the most effective in addressing their needs. The information the study gathered consisted of an examination of current literature and research, and contacts with first year teachers, mentors, and building administrators who were involved with the induction program. Information collected led to a descriptive statistical summary of findings. Recommendations were made toward the improvement of current induction programs as well as the creation of a mentor-protege program in districts where one does not exist
Rethinking the Classroom: One Department’s Attempt to Connect Student Learning and National Events
Communication programs have a rich anecdotal history of connecting student learning to real-world experience. Yet, the same programs, including ours, often privilege classroom-based instruction and instructor-led experiential learning over other types of experiences. When community organizers announced a national mega-event for our city, faculty in our communication department knew that we wanted to use it as a learning experience. We brainstormed ideas, most of which were classroom- and semester-based concepts typical of traditional topics courses. But, one of our faculty members suggested that we think outside of the concept of classroom. What resulted was a unique experience unlike any we had offered before: a valuable and compelling learning event that emerged from a successful faculty-staff-student-community partnership

Instructional Logistics and Chunque-Based Learning Systems
Existing instructional design and curriculum design strategy components were synthesized to provide a comprehensive set of design models for the development of learning systems. The term instructional logistics was coined to define the management of student progress through a series of customized learning experiences. Strategies were developed for the design of student-centered learning systems by partitioning a curriculum into meaningful and manageable pieces (called chunques) and by manipulating those pieces to create personalized and individualized paths through a series of self-contained learning experiences. Strategies were developed to organize a collection of chunques into a path based on initial simplified mental models designed specifically to make the subject matter more appropriate for novice learners. Two types of paths were proposed: paths created prior to instruction based on the best guess at what is optimal for the particular circumstances (anticipatory paths) and paths modified on the fly based on diagnostic information gathered during the learning process (adaptive paths).
Curriculum design decisions were based on two propositions: that curriculum decisions can be categorized as value-laden decisions, based on some conception of worth, or as technical decisions, based on instructional needs. The three souls proposition was developed, which proposes that educational goals can be categorized as education-to-be, sagacity-to-know, or training-to-do

Beyond Your Perception: An Exploratory Study of Black Parent-Daughter Relationships and Hip Hop Influences on Adolescent Girls
ABSTRACT
BEYOND YOUR PERCEPTION: AN EXPLORATORY STUDY OF BLACK PARENT-DAUGHTER RELATIONSHIPS AND HIP HOP INFLUENCES ON ADOLESCENT GIRLS
by
Sherell A. McArthur
This study is situated at the nexus of three bodies of literature and research and sought to contribute to all three: the socialization of Black girls, hip hop as a pedagogical tool and critical media literacy. My research explored how might the Black parent-daughter relationship serve as a vehicle by which the girls come to understand, submit to, and/or resist the stereotypical images prevalent in the hip-hop culture? I co-created a critical media literacy collective with high school, African American girls where we explored personal identity development in relationship to representations of African-American women in the media. It was through my interactions with the girls in this collective, named Beyond Your Perception (BYP). Through this collective, the primary data sources were qualitative interviews, focus groups, and documents. A thematic analysis revealed Black girls represent the dominant narratives within the cultural movement of hip hop by ascribing to cultural mores like fashion trends, hairstyles and language. They also consciously choose to resist the stereotypical imagery (e.g., loud, angry, sexually loose, etc.) and are able to compose powerful counter-narratives to the monolithic depictions of Black women in the media. By examining the data it was evident that parents engage with hip hop media by listening to the music and watching television shows and music videos, however the ways in which they engage their daughters in dialogue pertaining to the messages within hip hop media is sporadic and suggests the need for parents to become media literate. The implications of this study suggest the need for the creation of collaborative and emancipatory spaces for Black girls, media literacy education for parents, and culturally relevant pedagogy
