University Of Michigan-Dearborn Research Articles

Editorial Note

The first three articles in this issue of Polish American Studies were initially presented as part of a panel organized by Anna Müller at the annual conference of the Polish American Historical Association in New York in January 2019. The fourth article, authored by Anna Müller, the Frank and Mary Padzieski Endowed Professor in Polish/Polish American/Eastern European Studies in the Department of Social Sciences at the University of Michigan-Dearborn, is based on research conducted by her in Hamtramck for the exhibit “The People in Hamtramck,” sponsored by the Museum of Emigration in Gdynia, Poland, the Ministry of Foreign Affairs, Poland, and the University of Michigan-Dearborn. Together, the four articles, which appear in the year when the City of Hamtramck celebrates its centennial, ponder the history and the present of one of the largest Polonia communities in the United States, now in the process of economic, political, social, and cultural change.In the first article Karen Majewski, an eminent historian of Polonia as well as a former long-time mayor of Hamtramck, reflects on the city's political history, charting the trajectory of a local political scene dominated by Poles from the 1920s to more recent political competition from members of new ethnic groups who settled in the city in more recent decades.Sally Howell explores Hamtramck's present as the first Muslim majority city in the United States by focusing on the connection between the economic entrepreneurial activity of immigrants from Yemen and Bangladesh and the influence of religious cultural centers in downtown Hamtramck. Sunanda Samaddar Corrado continues this theme by examining the increased cultural presence and visibility of the Bangladeshi community in Hamtramck, ranging from the call to prayer controversy, which reverberated in national media, to another controversial decision to approve marijuana businesses in the city.In the final article, Anna Müller reflects on what it means to be Polish American to different representatives of the Polish ethnic community in the city. Using the concept of “tangible belonging,” Müller argues that each generation and wave of immigrants understood differently their Polish and Polish American identity within the unique social and cultural context of the city. Her article is illustrated by evocative portraits of Hamtramck's Polish personalities by photographer Tomek Zerek.In the Reviews section of this issue, our readers will find reviews of books by George W. Bush, Anthony Bukoski, Aleksandra Ziółkowska-Boehm, Anna Mazurkiewicz, and Lenny A. Ureña Valerio.

Virtual Tabadul: Creating Language-Learning Community Through Virtual Reality

This article presents on a multi-institution project that explains the development of Virtual Tabadul, which is an exchange program in virtual reality for English and Arabic foreign language and culture learning and community building amongst 1,200 US and the Middle East, and North Africa (MENA) college-aged youth. The program involves faculty, staff, and students at four institutions: Florida International University (U.S.), University of Michigan-Dearborn (U.S.), Oum El-Bouaghi University (Algeria), and Ibn Tofail University (Morocco). The project has been developed with generous funding from the Stevens Initiative and is the very first virtual exchange program for Arabic and English foreign language learning in virtual reality.

Driving maneuver early detection via sequence learning from vehicle signals and video images

Driving Maneuver Early Detection (DMED) is particularly useful for many applications of intelligent vehicle systems, including driver warning and collision avoidance systems. In this paper, we introduce a robust DMED model, denoted as University of Michigan Dearborn (UMD)-DMED, developed using innovative features and deep learning techniques. The UMD-DMED model contains three major computational components, distance based representation of driving context, combined vehicle trajectory features and visual features, and a Long Short-Term Memory (LSTM)-based neural network that captures temporal dependencies of driving maneuvers. To properly evaluate the performances of UMD-DMED, we developed two DMED systems based on the UMD-DMED model, one system is based on partially observed evidence of maneuver events, and another on features observed ahead of the time that driving maneuvers take place. We conducted the extensive experiments using a data set containing 1078 maneuver events extracted from 37 hours of real world driving trips. The results demonstrate that the UMD-DMED model is capable of learning the latent features of five different classes of driving maneuvers, i.e. left turn, right turn, left lane change, right lane change, driving straight. Comparing to four different state-of-the-art DMED systems, the UMD-DMED achieved better detection performances in both, the detection based on partial observations of driver maneuvering, and based on driving context observed ahead-of-time.

The Impact of Emotional Regulation Strategies on Pain Catastrophizing in the Context of Interpersonal Relationships.

The Communal Coping Model suggests that pain catastrophizing may serve to elicit support from others. What is not known is how emotional regulation, namely emotional inhibition, impacts pain catastrophizing within the context of an interpersonal relationship. Individuals who have a greater tendency to emotionally inhibit may have a greater likelihood to use catastrophizing as a means for seeking support, particularly in relationships characterized by satisfaction and emotional validation. Data were collected from 50 undergraduate couples at the University of Michigan-Dearborn. Participants were videotaped during the completion of an acute pain cold pressor task and completed measures involving pain catastrophizing, emotional inhibition, and relationship dynamics (ie, Ambivalence Over Emotional Expressiveness Questionnaire, White Bear Suppression Inventory, Dyadic Adjustment Scale). In addition, the videotaped interactions were coded for both invalidation/validation and overt expressions of pain catastrophizing. Emotional inhibition, and both validation and invalidation were associated with pain catastrophizing. Observed validation and invalidation were not, however, directly associated with relationship satisfaction. Hierarchical linear regression showed a significant interaction between thought suppression and relationship satisfaction to predict pain catastrophizing. Results show relationship satisfaction moderates the association between pain catastrophizing and thought suppression in a manner in which couples with high levels of relationship satisfaction who also engage in thought suppression are more likely to use pain catastrophizing as a cognitive strategy to elicit support. This study offers direction into treatment and suggests that couples based cognitive-behavioral treatments that aim to utilize adaptive cognitive and behavioral coping strategies, as well as emotional exploration and validation, may be beneficial.

TEACHING COURSES ONLINE: HOW MUCH TIME DOES IT TAKE?

Studies show that temporal factors like workload and lack of release time inhibit faculty participation in developing and teaching online courses; however, few studies exist to gauge the time commitment. This longitudinal case study, presented at the Seventh Annual Sloan-C International Conference on ALN, examined the amount of time needed to teach three asynchronous online courses at The University of Michigan-Dearborn from Winter 1999 through Winter 2000. Twenty-five students were enrolled in each course. Self-monitoring was used to measure the amount of time required to complete the following activities: 1) reading and responding to emails; 2) reading, participating in, and grading 10 online discussions; and 3) grading 15 assignments. Using a stopwatch, the investigator timed and recorded the number of minutes needed for each activity. Also, all messages and assignments were archived and frequency counts were recorded. The weekly, mean number of minutes and assignments was entered on line graphs for analysis. The data showed that teaching each online course required 3 to 7 hours per week, with the greatest number of emails and amount of time required during the first and last 2-weeks of the semesters. Participation in and grading of the discussions took the greatest amount of time and remained steady across the semester. However unlike many live courses, the students participated more in thediscussions than the instructor did. The number of assignments that were submitted each week steadily increased over each semester. This case study indicates that the time needed to teach online courses falls within the range of reasonable expectations for teaching either live or online courses and represents the beginning of this area of inquiry. Consequently, additional studies are needed with a variety of instructors across a variety of courses and disciplines to further pinpoint faculty time commitment.

Paul William Zitzewitz

Paul William Zitzewitz, a dedicated educator, noted textbook author, atomic physicist, and leader in the American Association of Physics Teachers (AAPT), passed away on 30 April 2013 in Northville, Michigan, at age 70 after a long battle with cancer. Paul William Zitzewitz PPT|High resolutionPaul was born in Chicago on 5 June 1942. While in high school, he developed a strong interest in science and had an early internship with IBM in downtown Chicago. After earning his BA in physics from Carleton College in Minnesota in 1964, Paul went to Harvard University and received his AM and PhD in physics in 1965 and 1970, respectively.Under the guidance of Nobel laureate Norman Ramsey, Paul did his thesis work on the atomic hydrogen maser. He focused on measuring the frequency shifts arising from collisions of the hydrogen atoms with the maser walls. That work led to a significant improvement in the accuracy of our knowledge of the maser transition frequency and to the maser’s use as a fundamental time standard. Paul’s wide-ranging curiosity led him, even as a graduate student, to think about the recently discovered millisecond-period pulsars as possible time standards.Between 1970 and 1972, Paul was a postdoc at the University of Western Ontario in Canada. He then spent a year at Corning Glass Works as a senior research scientist before being hired in 1973 as an assistant professor of physics at the University of Michigan-Dearborn. In 1978 he became an associate professor of physics, and in 1984, a professor.In his research at Dearborn, Paul concentrated on positrons and positronium. With colleagues at the University of Michigan in Ann Arbor, he made precision measurements of the decay rate of ortho-positronium.A dedicated teacher, Paul had several noteworthy achievements during his long career, including his reforms of upper-division laboratory, electronics, and advanced laboratory courses. For both in-service and pre-service elementary school teachers, he developed and taught three courses on science education. In recognition of his accomplishments in education, he was appointed a professor of science education in 2005. Paul served as chair of the department of natural sciences from 1999 to 2005 and associate dean of the College of Arts, Sciences, and Letters from 1988 to 1993. In 2009 he retired from his faculty positions.Paul’s Physics: Principles and Problems (McGraw-Hill/Glencoe, 2005) is a widely used high school textbook that has gone through nine editions and has been translated into several foreign languages. He also authored the second edition of The Handy Physics Answer Book (Visible Ink Press, 2011), which presents physics phenomena in easy-to-understand conceptual language for the general public.Paul was active in many physics and physics teachers’ organizations, including AAPT and the Detroit Metropolitan Area Physics Teachers. He served as president of AAPT’s Michigan section in 1996–97 and as treasurer and executive board member of the national AAPT from 2008 until his death. With the American Physical Society, Paul served on the Committee on Education and the Committee on Informing the Public, and he was chair of the Forum on Education in 1998–99. He received the distinguished service award from AAPT’s Michigan section in 2001. Among Paul’s many recognitions from the University of Michigan-Dearborn were the Distinguished Faculty Research Award in 1985 and the Distinguished Teaching Award in 2007.Being dedicated to K–12 education, in 2010 Paul and his wife, Barbara, generously endowed AAPT’s Excellence in Pre-College Teaching Award, now the Paul W. Zitzewitz Award for Excellence in Pre-College Physics Teaching.Throughout his life, Paul enthusiastically shared with his colleagues, students, children, and grandchildren his curiosity about the natural world; his love of scientific research, teaching, and learning; and his engaging sense of humor.© 2013 American Institute of Physics.

Innovations in collaboration in the design of a low mass vehicle

The Institute for Advanced Vehicle Systems at the University of Michigan-Dearborn conducts research on advanced vehicle systems. Its driving project was the design a low mass vehicle (LMV) 30% lighter than the Toyota Echo. Over 35 individual projects were conducted. Technical results and break-through technologies are summarised. The LMV project involved innovative collaboration among faculty researchers, students from three institutions and industry partners. One innovation was researchers working on a common driving project, assuring that individual projects complement each other. Another was utilising the experience and expertise of industry partners. A third was the automotive design studio, teaming engineering and design students with industry professionals to gain hands-on experience in automotive design. One outcome of LMV research was students gaining what the Accreditation Board for Engineering and Technology calls 'professional skills' – abilities to communicate effectively and be effective team players. Partner companies say they value graduates with these skills.

All Plants are "Exotic Invasives"

www.ethnobotanyjournal.org/vol6/i1547-3465-06-117.pdf Ethnobotany Research & Applications 6:117-119 (2008) Daniel E. Moerman, University of Michigan-Dearborn, 6515 Cherry Hill Rd., Ypsilalanti, MI 48198, U.S.A. dmoerman@umd.umich.edu Why? First, the Hawaiian islands are the remains of massive volcanoes which arose atop a hot spot in the Pacific plate. They were formed of sterile molten rock. My understanding is that the endemic higher plant flora of Hawai`i, preceding human occupation, is descended from approximately 40 original plants, seeds, roots, or whatever, deposited after storms, or from lost birds, or the like. The first of those 40 landed on one of the islands which existed at the time (they come and go in what is apparently something like a 15 million year cycle) and somehow “took root,” so to speak. An omniscient observer would have to consider this first plant on a totally sterile island as mighty exotic, and surely invasive. This first species spread as far as it could, and, as did the following 39, diversified into different niches (or something like that). Each species moved forward, and probably backward, with newly evolved species probably invading the landscapes of their ancestors (one count shows some 1500 species evolved from the 40 originals). Some of them managed somehow to float or be carried to other islands. While there are “island endemics,” others seem to have moved throughout the island chain. The youngest islands are to the east, the oldest to the west (a number of them totally submerged by now). But the point here is that each and every one of those species moved somewhere from somewhere else. A particular individual new species of the adaptive radiation may have emerged in one of those All Plants are “Exotic Invasives”

Suspension design and dynamic analysis of a lightweight vehicle

This paper discusses the development of suspension systems for a lightweight vehicle being developed at the University of Michigan-Dearborn, called the Low Mass Vehicle (LMV). A performance target vehicle (reference) model was first developed using a multi-body vehicle dynamics program (ADAMS/Car) and its responses of kinematics, compliance and dynamic step steer tests were validated with the test data. The suspension design parameters of the LMV were then tuned to meet the handling characteristics of the reference vehicle and the effects on vehicle responses of loading condition changes were investigated. The roll stability of the LMV was also assessed by performing fixed timing fishhook manoeuvre. The vehicle responses of the LMV with the developed suspension systems correlate well with those of the reference vehicle and provide good roll stability in the fishhook manoeuvre.

Technology: A Tool for Knowledge Construction in a Reggio Emilia Inspired Teacher Education Program

This article describes the application of technology in Reggio Emilia inspired early childhood and teacher education programs at the University of Michigan-Dearborn. We have found that technology used in a Reggio inspired program can be a valuable tool for the representation and organization of ideas, collaboration among a specific learning community, visualization and reflection on thinking, and communication of learning to the broader community. Our experiences and reflections suggest that the integration of technology in a Reggio inspired curriculum supports knowledge construction of both children and student teachers.

Results were interpreted in terms of the three air-flow geometries described in the literature: chamber flow, channelized flow, and pervasive/bubbly flow. Compared to sparging experiments in monostratigraphic layers, AS of coarsening-upward sequences can increase the extent of the sediment column affected by air because of changes in air-flow geometry and/or sparge angle at strata transition boundaries. AS of fining-upward sequences can also increase the extent of sediment affected in an overlying unit in which channelized flow occurs by generating multiple air-source points. Laboratory simulations of the AS injection interval, representative grain size, and stratified saturated zone of a field site were also performed. These experiments indicated the potential occurrence of chamber flow at the site and revealed the effect of pulsed AS. The effect is to fill in areas of the sedimentary column between air-flow chambers that otherwise would not be affected by air during continuous sparging. This phenomenon, observed in the laboratory, is a likely explanation for remediation performance at the site.

A Report on CUR 2000: The Many Facets of Undergraduate Research

Eighth National Conference of the Council on Undergraduate The Many Facets of Undergraduate Research, was held at College of Wooster in Wooster, Ohio, June 22-24, 2000. There were more than 600 participants. Conference co-chairs Charlotte Otto (University of Michigan-Dearborn) and Patricia DeWinstanley (Oberlin College), with College of Wooster local committee co-chairs Don Jacobs and Lori Bettison-Varga, assembled a variety of plenary sessions, workshops, poster sessions, and symposia to explore a rich array of themes. Institutionalization of undergraduate research, facility design and renovation, faculty development, funding opportunities, collaborative research, assessment of research activities, and interdisciplinary research were among the issues highlighted. More than 100 workshops given by 230 presenters provided opportunities for faculty and administrators to exchange ideas on undergraduate research and science education.

The Detroit Area Pre-College Engineering Program, Inc. (DAPCEP)

In 1976 the Detroit Area Pre-College Engineering Program, Inc. (DAPCEP) began with 245 students. The overall goal of DAPCEP was to increase the number of local middle school and high school minority (Black, Hispanic, and Native American) students who are motivated and prepared academically to choose careers in science, engineering, and other technical fields. To that end DAPCEP provides instructional and motivational activities and intervention throughout the year including the summer as well as throughout the week including Saturdays for minority students in grades 7-12. Its services cover a broad spectrum of activities, one of the characteristics of an effective program. The earliest participating institutions included the University of Michigan, Michigan State, one Detroit high school, and two middle schools. By 1989 the program had expanded to include 8 area universities (University of Detroit, University of Michigan-Ann Arbor, University of Michigan-Dearborn, Michigan State University, Oakland University, Wayne State University, GMI Management Institute, and Lawrence Technological University), 24 high schools, 36 middle schools, and 2,000 students (1,300 middle school and 700 high school students). The program was initiated with a grant from the Alfred P. Sloan Foundation and it has received on-going support and funding from many different sources. The Detroit Public School System (DPSS) supports some of the program's activities and participating universities provide in-kind contributions of facilities, support staff, and other types of aid. Major corporations and businesses supply speakers, corporate financial aid, and summer employment to participants. Recently DAPCEP has received a large grant from the National Science Foundation to revise and upgrade its middle school pre-engineering curriculum and to develop videotapes and supplementary mathematics teaching materials. DAPCEP is governed by an 18-member board of directors representing DPSS, local universities, technical employers, and parents. The board has six representatives from corporations, six university representatives, three school system representatives, and three parent members. An executive director is responsible to the board for the implementation of its policies.

The Donne variorum textual collation program

At its organizational meeting in the fall of 1981, the Advisory Board of The Variorum Edition of the Poetry of John Donne debated the merits of existing editions of Donne's poetry. Aware of approximately eighty-seven manuscript sources and nearly 400 seventeenth-century printings of individual Donne poems unknown to Donne's previous editors, we decided to make a newly edited text a part of the project. Responsibility for developing such a text was accepted by John T. Shawcross (University of Kentucky), Ted-Larry Pebworth (University of Michigan-Dearborn), and ErnestW.
