- Description:
- The 2023 DREAM Street Fair was a free, family-friendly festival celebrating our neighborhood’s spirit of community, entrepreneurship, arts and culture, and healthy living. Hosted by Jermaine “Big Fresh” Carey and rising comedian Nadirah Pierre, and headlined by multi-platinum recording artist Freeway, the event featured performances by Khalil Ismail, Ain’t Afraid, Journalist 103, Tariq Toure, and Hardcore Detroit. It was an afternoon of empowering poetry, soulful vocals, classic hip-hop, world-class break dancing, and fun interactions with the crowd. Nearly 40 vendors, including some of the area’s best food trucks, set up shop to interact with 3,000 attendees over the course of the day. And children were treated to bounce houses, button-making, book readings, and outdoor video gaming., Primarily hosted by Dream of Detroit, a local organization combining community organizing and development to revitalize a Westside neighborhood, the Street Fair was a true community partnership. The Detroit Repertory Theatre, the city’s longest-running neighborhood theatre, opened up their lot to sell treasured props from 60 years worth of performances. The HUDA Clinic, our local free health care center, offered dental screenings, health assessments and referral services. And, at the HUDA Urban Garden, attendees picked fruits and vegetables, and learned creative ways to make tasty and healthy meals and snacks. Putting on a free neighborhood festival of this scale would have been impossible without the support of Egalitarian Metropolis and sponsors like Mercy-USA. Plainly put: these types of events don’t usually happen in neighborhoods like ours. That’s why, for nearly a decade, Dream of Detroit has been working toward a truly inclusive Detroit recovery where the idea that “every neighborhood has a future” is more than just a political slogan., and Our goal with this event was to host an excellent celebration for our community members, and to shine a spotlight on the community-led placemaking and development happening in our neighborhood. The DREAM Street Fair stands alongside other initiatives like the DREAM Community Land Trust, our partnership with ProsperUs Detroit Entrepreneurship Workshop, and our membership in the Coalition for Property Tax Justice, as just some of the programs we are involved in to do our small part in creating an Egalitarian Metropolis.

- Description:
- Launched in response to the growing crisis of narrative infrastructure, the Detroit River Story Lab is a collaborative, public-facing initiative that leverages the sociocultural, economic, and ecological centrality of the Detroit River corridor to reimagine it as an urban case study in narrative placemaking and civic renewal. Beginning with the premise that place-based storymaking is vital to sustaining democratic values and community capacity for self-determination, the Lab partners on projects designed to support the narrative capacities of local urban communities through the story-telling channels of community journalism, place-based education, and public history., There are many stories from across a variety of periods and contexts that foreground the prevalence of aquatic racialization in our region. These include the legal restrictions placed on Black residents’ access to the Detroit River in the aftermath of the successful escape of Thornton and Lucie Blackburn from Kentucky slave catchers in 1833, repeated episodes of the often violent expulsion of Black workers and residents from Wyandotte and other sundown towns along the Detroit River between the 1870s and 1940s – and the repeated erasure of these stories from official published histories of these towns, the Bob-Lo Excursion Company’s policy, in the 1930’s and 40’s, of barring Blacks from the ferry boats that provided access for Detroiters to the Boblo Island amusement park, a policy famously up-ended by the US Supreme Court in 1948 after being challenged by a 24-year-old Detroit, Sarah Elizabeth Ray, after being ordered to leave the boat, the demolition of the predominantly Black, riverside neighborhood of Black Bottom in Detroit in the 1950s in the name of urban renewal, the UN’s 2014 appeal, on the grounds of basic human rights, for the city of Detroit to restore access to water sourced from their own Detroit River to residents who can’t afford monthly water bills, and consumption restrictions on Detroit River fish important to local populations owing to long histories of environmental degradation., and Considered together, these cases would seem to point to an undertheorized dimension of racialized systems of hierarchy and exclusion in the Great Lakes region and possibly the US more generally. The origins and long-term effects of zones of racial exclusion in the economically decisive domains of work, education, and housing are by now well known. The role of waterways as similarly delineated spaces of privilege and oppression is less commonly noted; in a state whose history has been so thoroughly defined by its lakes and rivers and so regularly scarred by racial conflict, the phenomenon of aquatic racialization calls out for integrative examination and public reckoning.

- Description:
- Michigan-Mellon’s renewed Egalitarian Metropolis cycle of funding focuses on the city of Detroit and ways that creative practice and the urban humanities can equitably address urban recovery. In tangible ways, The University of Michigan Architecture Preparatory Program (ArcPrep) is already doing just that: creating a sense of optimism and agency for Detroit public high school juniors interested in design and its affiliated fields. , Through an intensive, semester-long studio taught by our Mellon Fellows in Architecture, young designers learn to critically discern Detroit’s complex spatial histories as they explore ways to shape the city’s possible futures. The program takes the students’ talents, creativity, and expertise very seriously, nurturing an inclusionary pedagogical model based broadly on egalitarian educational ideals. In the process, we bring together a network of Taubman College faculty and students, Detroit institutions, community and government organizations, and professional enterprises into conversation and collaboration with students. In the past, ArcPrep has partnered with the Detroit Public Library, the Detroit Institute of Arts, the Detroit Cultivator Community Land Trust, and the Sidewalk Festival, to name a few. With each partnership, we situated culturally contingent, place-based design exercises for students to directly engage with the city and its leaders., and More information about the Michigan Architecture Preparatory Program (ArcPrep) can be found at https://taubmancollege.umich.edu/academics/pre-college-programs/michigan-architecture-prep/

- Description:
- The study that produced this corpus was conducted by a joint Task Force on Career Progression charged by the Association of University Presses and Society for Scholarly Publishing in January 2022, and strengthened by the addition of the Association of Learned Professional and Scholarly Publishers in 2023. The goal of the Career Progression Task Force’s job classification project was to develop a dataset of job descriptions that identify typical skills and responsibilities associated with various roles in publishing, analysing these descriptions to elucidate the skills and qualifications needed for the jobs and career advancement and disseminate the results in a way that is useful to employers and employees alike. The work of the Task Force was made possible by the doctoral internship program at the University of Michigan's Rackham Graduate School, which supported the involvement of Michelle Lam and Lauretta Cheng. The project also involved master’s degree students at George Washington University and the University of Michigan. and In total, the corpus contained 1089 unique job description texts. A wide range/variety of positions (n=666) across functional areas were represented in the corpus. The majority of the texts came from publicly available job postings. This form of text is created to advertise positions and is typically neither as detailed nor as objective as internal position descriptions, which were contributed either individually or as a group from a particular publisher.

- Program Description DoT was founded in 2012 with a mission to increase diversity amongst medical professionals by preparing students from underrepresented communities in Detroit to successfully pursue careers in healthcare. Our program builds on a partnership between Cass Technical High School (CTHS) and the University of Michigan Medical School (UMMS). The CTHS student body is reflective of the Detroit population with more than 80% of students identifying with racial and ethnic minority backgrounds. Students with an interest in healthcare apply for the program as ninth graders. In recent years, the program has received over 60 applications for approximately 30 positions in each grade. DoT’s unique strength lies in its longitudinal structure. There are three branches of the program – Foundations (ninth and tenth grade), Rising (eleventh and twelfth grade) and Succeed (undergraduate). Ninth graders start out in DoT Foundations. Each student is paired with a first-year medical student mentor at UMMS for the entire academic year. DoT students travel to UMMS every month for a visit day, with activities designed to give students hands-on experiences in healthcare, such as suturing and ultrasound skills in the simulation center, and clinical shadowing. Students then meet with their medical student mentor over lunch. The latter part of the day is dedicated to working on their capstone projects. For the capstone projects, students work in small teams led by medical student leaders to identify a community health issue, partner with a local organization, and present their proposed solutions at a formal symposium at the end of the year. , Transition to Virtual Programming In light of the recent COVID-19 pandemic, a growing number of universities cancelled all campus events including those of pipeline programs. We felt that our programming offered an important service to our students that would be greatly missed, so our team worked to quickly create and implement a virtual program. We ensured that each of our students had access to technology at home and those who did not were offered scholarships. During our introductory student session and new parent meeting, our leadership team discussed how to set up a Gmail email address for weekly communications and taught the students how to use Zoom, Google Drive, Google Docs and Google Sheets for online learning collaboration. For the virtual Foundations program, we offered 1-hour seminars each month, where a physician was invited to give a 30-minute presentation about different organ systems, followed by a 30-minute case-based session where students worked with medical student mentors to apply their new knowledge. We also created novel sessions such as “The Path to College and Medical School” and collaborated with members of the Black Medical Association (BMA) and Latin American and Native American Medical Association (LANAMA) to host a panel session where students could learn from medical students who identified as URiM. For the mentorship aspect, we created “pods” of Foundations, Rising, and Succeed students along with medical student and physician mentors. The Foundations students and mentors met every month for an hour on Zoom, a virtual communication platform, to work on their Capstone project. Rising and Succeed students joined the group for three full-pod meetings. The goal was to increase near-peer mentorship and connections between DoT students at all levels. , and Study Population Due to the virtual nature of the 2020-2021 program, we accepted 100% of 9th grade applicants from CTHS. We also expanded our reach to a new school, The School at Marygrove (TSM), which is also located in Detroit, Michigan. TSM is involved in the Detroit-20 Partnership with the University of Michigan College of Education and includes a novel three-year residency program for novice teachers. During the 2020-2021 school year, 108 students participated in the Foundations programming with 72 of them being 9th graders and 36 being 10th graders. The students were mostly from CTHS with 12 students out of the 108 total being from TSM. Students were predominantly from an African American/Black racial background (68.4% from N=98 respondents). The students were representative of their respective schools. The majority of students at CTHS identify as black, come from low-income homes, and have variable levels of parental education.

- Description:
- What does/can/should an egalitarian metropolis look like? And how does a focus on Detroit allow us to ask and answer these conceptual—and practical—questions in ways that draw on a variety of disciplines including architecture, history, urban planning, and the urban humanities?, This course offers an interdisciplinary perspective on urban studies, urban design, and the ways that concerns around social justice and equity can influence how we think about cities in the past, present, and future. Drawing on a range of faculty expertise in the College of Literature, Science, and the Arts and Taubman College of Architecture and Urban Planning, this team-taught course also incorporates the voices of practitioners and community members involved in current attempts to revitalize Detroit and “Detroit-like” cities in the United States and elsewhere. By “Detroit-like cities” we mean urban areas that have experienced negative population growth, deindustrialization, economic disinvestment, racial stratification, environmental injustices, and concomitant crises in housing, health care, policing, criminalization, and education. At the same time, Detroit and Detroit-like cities offer opportunities to conjoin critical humanistic inquiry, urban design, and policy solutions for building more equitable and sustainable cities., and This course is co-designed and co-taught as part of the Egalitarian Metropolis Project, which is a partnership between the Taubman College of Architecture and Urban Planning and the College of Literature, Science, and the Arts. It combines traditional course materials with a team-based orientation to teaching and learning.

- Description:
- The H2O concentration and H2O/Ce ratio in olivine-hosted melt inclusions are high (H2O up to 1410 ppm; H2O/Ce up to 77) in lunar sample 74220 but lower (H2O up to 430 ppm; H2O/Ce up to 9.4) in all other lunar samples studied before this work. This difference is absent for other volatiles (F, S, and Cl) in melt inclusions in 74220 and other lunar samples. Because H2O (or H) is a critical volatile component with significant ramifications on the origin and evolution of the Moon, it is important to understand what causes such a large gap in H2O/Ce ratio between 74220 and other lunar samples. Two explanations have been advanced. One is that volcanic product in sample 74220 has the highest cooling rate and thus best preserved H2O in melt inclusions compared to melt inclusions in other samples. The other explanation is that sample 74220 is a localized heterogeneity enriched in some volatiles. To distinguish the two possibilities, here we present new data from three rapidly cooled lunar samples: olivine-hosted glassy melt inclusions (OHMIs) in 74220 regolith and 79135 regolith breccia, and pyroxene-hosted glassy melt inclusions (PHMIs) in 15597 pigeonite basalts. If the gap is due to the difference in cooling rates, samples with cooling rates between 74220 and other studied lunar samples should have preserved intermediate H2O concentrations and H2O/Ce ratios. Our results show that melt inclusions in 79135 and 15597 contain high H2O concentrations (up to 969 ppm in 79135 and up to 793 ppm in 15597) and high H2O/Ce ratios (up to 21 in 79135 and up to 13 in 15997). Combined with literature data, we confirm that H2O/Ce ratios of different lunar samples are positively correlated to the cooling rates and independent of the type of mare basalts. Our work bridges the big gap in H2O/Ce ratio among 74220 and other lunar samples. We hence reinforce the interpretation that the lunar sample with the highest cooling rate best represents pre-eruptive volatiles in lunar basalts due to the least degassing. H2O, F, P, S and Cl concentrations in the lunar primitive mantle are also estimated in this work. and *** 2024-03-19: In addition to the files in the previous version, this updated deposit contains more data files as the supplementary files of the paper.

- Description:
- Accurate estimation of hydro-meteorological variables is essential for adaptive water management in the North American Laurentian Great Lakes. However, only a limited number of monthly datasets are available nowadays that encompass all components of net basin supply (NBS), such as over-lake precipitation (P), evaporation (E), and total runoff (R). To address this gap, we developed a daily hydro-meteorological dataset covering an extended period from 1979 to 2022 for each of the Great Lakes. The daily P and E were derived from six global gridded reanalysis climate datasets (GGRCD) that include both P and E estimates, and R was calculated from National Water Model (NWM) simulations. Ensemble mean values of the difference between P and E (P – E) and NBS were obtained by analyzing daily P, E, and R. Monthly averaged values derived from our new daily dataset were validated against existing monthly datasets. This daily hydro-meteorological dataset has the potential to serve as a validation resource for current data and analysis of individual NBS components. Additionally, it could offer a comprehensive depiction of weather and hydrological processes in the Great Lakes region, including the ability to record extreme events, facilitate enhanced seasonal analysis, and support hydrologic model development and calibration. The source code and data representation/analysis figures are also made available in the data repository.

- Description:
- This dataset presents stable isotope data (d13C, d18O, D47, D17O) from Holocene lake cores from three lakes in the Peruvian Andes (Lakes Junin, Pumacocha, and Mehcocha). We also present new radiocarbon (14C) data and core age models for Lakes Junin and Mehcocha. We use these data to explore trends in lake water temperatures and evaporative state (i.e., water balance) over the Holocene. Our clumped isotope (D47) results suggest lake water temperatures at all three lakes were stable over the Holocene and similar to present day lake temperatures. Our triple oxygen isotope (D’17O) results illustrate that lake water balance at all three lakes was variable over the Holocene and tracks changes in austral summertime insolation, suggesting a connection between central Andean water balance and the South American summer monsoon (SASM).

- Description:
- In the recent geological past, Earth’s magnetic field reduced to 4% of the modern values and the magnetic poles moved severely apart from the geographic poles causing the Laschamps geomagnetic excursion, which happened about 41 millennia ago. The excursion lasted for about two millennia, with the peak strength reduction and dipole tilting lasting for a shorter period of 300 years. During this period, the geomagnetic field exhibited significant differences from the modern nearly-aligned dipolar field, causing non-dipole variables to mimic a magnetic field akin to the outer planets while displaying a significantly reduced magnetic strength. However, the precise magnetospheric configuration and their electrodynamic coupling with the atmosphere have remained critically understudied. This dataset contains the first space plasma investigation of the exact geomagnetic conditions in the near-Earth space environment during the excursion. The study contains a full 3D reconstruction and analysis of the geospace system including the intrinsic geomagnetic field, magnetospheric system and the upper atmosphere, linked in sequence using feedback channels for distinct temporal epochs. The reconstruction was conducted using the LSMOD.2 model, Block Adaptive Tree Solar wind-Roe-Upwind Scheme (BATS-R-US) Model and the MAGnetosphere-Ionosphere-Thermosphere (MAGNIT) Auroral Precipitation Model, all of which are publicly-available models. The dataset contains the raw data from each of these models, in addition to the images/post-processing results generated using these models. Paleomagnetic data produced by LSMOD.2 can be visualized using a combination of linear plotting and contour plotting tools available commonly in visualization software like Python (e.g. Python/Matplotlib) or MATLAB. Standard tools to read and visualize BATS-R-US and MAGNIT output are already publicly available using IDL and Python (see SpacePy/PyBats - https://spacepy.github.io/pybats.html). For information and details about the post-processed data, visualization and analysis, please contact the authors for details. The anthropological dataset can be visualized using a shape file reader (e.g. Python/GeoPandas) and a linear plotting tool (e.g. Python/Matplotlib).

- Description:
- As part of a project to develop side impact test procedures for evaluating wheelchairs, wheelchair tiedowns and occupant restraint systems (WTORS), and vehicle-based occupant protection systems for wheelchair seating stations, we created validated finite element (FE) models to support procedure development. Models were constructed using LS-DYNA. Dynamic sled tests were performed to validate the FE models of surrogate fixtures and commercial hardware. Validated FE models were developed for the Surrogate wheelchair base (SWCB), Surrogate wheelchair for side impact (SWCSI), a manual wheelchair (Ki Mobility Catalyst 5), and a power wheelchair (Quantum Rehab Edge 2.0). Additional FE models of a heavy-duty anchor meeting the Universal Docking Interface Geometry (UDIG), surrogate four-point strap tiedowns (SWTORS), a traditional docking station, and the surrogate wall fixture were also developed.

- Description:
- Inland lakes play a critical role in ecosystem stability, and robust validation of lake models is essential for understanding their dynamics. While remote sensing data can assist with lake surface temperature validation, in situ data typically provides more accurate, reliable data not limited to only the lake surface. However, in situ temperature data for many individual lakes, particularly in North America, is difficult for researchers to quickly access in a standardized format. This database offers a well-organized collection of in situ near-surface and subsurface temperatures from 134 sites divided among 29 large North American inland lakes collected from a variety of sources. The database includes multiple subsurface temperatures throughout the depth profile of 84 of these sites, providing comprehensive data for lake model evaluation. All lakes selected for this database are large enough (over approximately 30 km^2 to be represented by large-scale operational weather models, supporting robust lake model validation efforts on the lakes that have the greatest impact on climatology.

- We conducted a mixed-methods study to understand how financial incentive programs impact transitions to cover cropping in Michigan. Michigan farms span a wide range of soil types, climate conditions, and cropping systems that create opportunities for cover crop adoption in the state. We tested the relationship between Environmental Quality Incentives Program (EQIP) payments for cover crops and cover crop adoption between 2008-2019, as measured by remote sensing. Panel fixed effects regressions showed that EQIP increased winter cover crop presence. Every EQIP dollar for cover crops was associated with a 0.01 hectare increase in winter cover, while each hectare enrolled in an EQIP contract for cover crops was associated with a 0.86 – 0.93 hectare increase in winter cover.
