ABO: Interactive Journal for Women in the Arts, 1640–1830
Four colleagues--a faculty member, a digital services librarian, a research librarian, and a curator of Special Collections--take turns describing their role in creating an undergraduate student project around an eighteenth-century almanac that belonged to Marie-Antoinette. In recounting the steps taken, the collaborative process, the student research, and the analysis of the contents of the Trésor des Grâces almanac, we share the lessons learned for completing a digital exhibit over the course of one semester.
Expanding Capacity To Serve Multilingual Learners: A University-School District Partnership, Beth Clark-Gareca, Kim Fontana
Expanding Capacity To Serve Multilingual Learners: A University-School District Partnership, Beth Clark-Gareca, Kim Fontana
Excelsior: Leadership in Teaching and Learning
In a time of new teacher certification requirements in New York, school districts are grappling with how to meet the regulatory expectations imposed by Commissioner’s Regulations Part 154. One way that schools are solving staffing challenges is by forging new collaborations with university partners to expand their collective capacities to serve Multilingual learners (MLLs). In this article, we document a partnership between SUNY New Paltz’s Teaching English to Speakers of Other Languages (TESOL) program and the Pawling Central School District during the 2017-18 academic year. We describe the partners’ distinct roles in the university-district collaboration, and discuss the logistical considerations …
Media Literacy And Climate Change In A Post-Truth Society, James S. Damico, Mark Baildon, Alexandra Panos
Media Literacy And Climate Change In A Post-Truth Society, James S. Damico, Mark Baildon, Alexandra Panos
Journal of Media Literacy Education
In this article we draw from ecolingusitics (Stibbe, 2015) and a civic media literacy framework (Author, in press; Masyada & Washington, 2016) to consider what happened when three pairs of preservice teachers with different academic backgrounds and climate change beliefs jointly evaluated the reliability of two media sources that make opposing arguments about climate change. An ecolinguistics perspective attends to the environmental impact of the “stories-we-live-by” (Stibbe, 2015) and a civic media literacy lens highlights the centrality of dialogue and deliberation along with critical reading when evaluating the reliability of information sources about complex socioscientific topics like climate change. Our …

A Scholar–Practitioner Stance: Practices Of Social Justice And Democracy, Patrick M. Jenlink
School Leadership Review
Crossing the threshold into a new millennium has been hallmarked by a series of defining events, which have shaped, irrevocably, society and its educational system. These events include the standards and accountability movement, the federal mandate of No Child Left Behind of 2001, the fifty-year anniversary of Brown v. Board of Education and the realization of how far we are from obtaining its promise, and the demographic shifts in population density and racial makeup nationally and particularly in urban centers, to mention a select few of the more profound historical events. Issues of diversity, both inter and intragroup, further illuminate …

Disproportionate School Disciplinary Responses: An Exploration Of Prisonization And Minority Threat Hypothesis Among Black, Hispanic, And Native American Students, Meghan M. Mitchell, Gaylene Armstrong, Todd A. Armstrong
Disproportionate School Disciplinary Responses: An Exploration Of Prisonization And Minority Threat Hypothesis Among Black, Hispanic, And Native American Students, Meghan M. Mitchell, Gaylene Armstrong, Todd A. Armstrong
Criminology and Criminal Justice Faculty Publications
This research tests two potential explanations of school disciplinary responses: minority threat hypothesis and prisonization of schools. Data from the Arizona Safe and Drug-Free Schools (SDFS) survey and Arizona Youth Survey (AYS) are analyzed using ordinary least squares (OLS) regressions. Findings demonstrate that the percentage of Black, Hispanic, and Native American students was not associated with exclusionary responses to school misconduct, but was linked to decreases in mild and restorative disciplinary practices. Findings support the hypothesis that minority threat reduces access to mild and restorative disciplinary responses. Although, further research is needed on the roles of mental health professionals and …

Analysis Of The Economic Development Of Statesboro, Georgia’S Blue Mile: A Structural Approach For Diversification, Cadence Dwyer
Honors College Theses
The Blue Mile has become a center for Statesboro’s Economic Development plan of business diversification and downtown revitalization. Downtown revitalization is important not only to existing businesses but also to expanding the property tax base. The gauging of revitalization and diversification in the field of community development has been overlooked in favor of qualitative generalizations. Burayidi’s Scorecard is used as a basis to establish a standard for the structural analysis tests conducted to measure business diversification.
Teacher Action Research In Elementary Social Studies: Use Of Ipads In 6th Grade Geography Instruction, Heather Leaman, Robert Corcoran
Teacher Action Research In Elementary Social Studies: Use Of Ipads In 6th Grade Geography Instruction, Heather Leaman, Robert Corcoran
i.e.: inquiry in education
A university instructor and master teacher describe the limited examples of practitioner research in elementary social studies found in traditional publications. They present a social studies practitioner research project that investigated the use of various technologies in 6th grade geography to improve student engagement, collaboration and academic success. The authors suggest that practitioner research provides a structure for elementary teachers to investigate questions related to student learning of key social studies content, the social studies curriculum, and related skills. They suggest that practitioner research, as professional development or alternative to traditional teacher evaluation requirements, creates opportunities for elementary school …

First Nations Gaming In Canada: Gauging Past And Ongoing Development, Yale Belanger
First Nations Gaming In Canada: Gauging Past And Ongoing Development, Yale Belanger
Journal of Law and Social Policy
Canada's First Nations gaming industry, now entering its third decade of operations, includes sixteen for-profit casinos operating in British Columbia, Alberta, Manitoba, and Ontario (two charity casinos also operate in Ontario) and eleven Nova Scotia First Nations operating just under six hundred Video Lottery Terminals (VLTs) annually generating approximately one billion dollars gross revenues. Each of these sites was constructed with the goal of generating revenue for economically struggling communities, but in most cases, they quickly became the lightning rod of a complex sovereignty discourse underlined by First Nations claims that they possessed the inherent right to control on-reserve economic …
A Tale Of Two Casinos: Unequal Spaces Of Local Governance, Alexandra Flynn
A Tale Of Two Casinos: Unequal Spaces Of Local Governance, Alexandra Flynn
Journal of Law and Social Policy
Local actors, including resident and business associations, do not simply influence decision-makers, but can also reshape the purportedly neutral governance model within which decision-making takes place. In big cities like Toronto, this reshaping exacerbates the existing geographic and socio-economic unevenness. The work of James Scott, Mariana Valverde, and Cheryl Teelucksingh helps to explain how local actors interface with seemingly neutral governance bodies to have their interests heard, particularly in relation to locally undesirable land uses. The paper considers two case studies detailing the governance practices at work in differing decisions about casinos in the City of Toronto. A 2012-2013 debate …
Regulation And Resistance In Canadian Bingo Halls: A Socio-Legal Account, Kate Bedford
Regulation And Resistance In Canadian Bingo Halls: A Socio-Legal Account, Kate Bedford
Journal of Law and Social Policy
Bingo is a key lens through which to explore how regulation shapes (or fails to shape) different meanings of gambling, and by extension the different meanings attached to speculation in everyday life. In Canada, bingo is played in a highly distinctive gambling environment that is now being subjected to more standardised rules, often drawn from casinos. In this article, I consider how workers and players in Canadian bingo halls are affected by shifting landscapes of provincial bingo regulation. By exploring smoking bans and new rules on touching cash, I ask: what is happening to bingo and its distinctive player demographic …

Keeping Chance In Its Place: The Socio-Legal Regulation Of Gambling, Kate Bedford, Donal Casey, Alexandra Flynn
Journal of Law and Social Policy
In the winter of 2010, driving through a blizzard to a research interview outside of Ottawa, one of the co-editors of this special issue—Kate Bedford—slid and spun off the road in her rental car. The interviewee—an 80-year-old man who organized a small weekly bingo game—helped dig her out. Sitting in the community centre with him afterwards, thawing, there was ample opportunity for Bedford to reflect on the diverse meanings attached to gambling and the complex ways in which it is regulated. The interviewee talked about ‘use of proceeds’ forms and validating expenses payments for volunteers, describing a gambling landscape that …

Prioritizing Suitable Locations For Green Stormwater Infrastructure Based On Social Factors In Philadelphia, Zachary Christman, Mahbubur Meenar, Lynn Mandarano, Kyle Hearing
School of Earth & Environment Departmental Research
Municipalities across the United States are prioritizing green stormwater infrastructure (GSI) projects due to their potential to concurrently optimize the social, economic, and environmental benefits of the “triple bottom line”. While placement of these features is often based on biophysical variables regarding the natural and built environments, highly urbanized areas often exhibit either limited data or minimal variability in these characteristics. Using a case study of Philadelphia and building on previous work to prioritize GSI features in disadvantaged communities, this study addresses the dual concerns of the inequitable benefits of distribution and suitable site placement of GSI using a model …

Constructing A Data-Based Mortality Profile For Avian Tower Kills At Telecommunication Towers In Illinois, Rachel Dipietro
Theses and Dissertations
During spring and fall seasons, Neotropical migratory passerines travel nocturnally across the Western Hemisphere between their wintering and breeding grounds, often encountering man-made threats. One hazard that has gained considerable publicity in recent decades is the communication tower. While there have been many tower kill studies recorded, there has been no attempt at predicting the risk of towers based on their different attributes (e.g., height, type of light, landscape placement) spatially on a regional scale. The objective of this study was to create seasonal mortality profile maps in GIS for Illinois, based on tower attributes combined with key factors such …

Making The Best Out Of The Worst: Utilizing Indonesia’S Existing Laws To Protect Asylum Seekers In Transit, Tanita Dhiyaan Rahmani
Journal of Islamic Law Studies
Being a party in the 1951 Convention on the Status Relating to Refugees and its 1967 Protocol is not an exclusive solution to legal protection of asylum seekers and refugees in Indonesia. Although the Government of Indonesia has not ratified both instruments, it has acknowledge the protection of asylum seekers and refugees under the People Consultative Assembly (MPR) Decree Number XVII Year 1998 and Law Number 37 year 1999 regarding Foreign Relations. A 2016 United Nations High Commissioner for Refugees reported that Indonesia has become a transit destination for more than 13,000 asylum seekers and refugees, including nearly 1,000 Rohing- …

Proglacial streams deliver melt water and chemical weathering products, including nutrients and radiogenic isotopes, from continental ice sheets to the ocean. Weathering products are also delivered to the ocean in non-glacial streams that form following ice sheet retreat and are disconnected from ice sheet meltwater by hydrologic divides. If weathering reactions differ in non-glacial and proglacial stream catchments, the streams could deliver different types and magnitudes of solutes to the ocean, depending on relative discharge volumes. Unlike proglacial streams, however, little is known of non-glacial stream solute compositions or discharge. Here we show specific discharges are similar from a …

Ambergris, which is a coprolith originating from the sperm whale, has been found only rarely, but for centuries, as jetsam on beaches all over the world. There are no reliable data indicating how long such samples may have remained at sea, with unsubstantiated accounts suggesting maybe decades. Here, we obtained over forty jetsam samples, many collected on known dates, from mostly known beach locations across the globe. Such an inventory of verified jetsam ambergris is unprecedented. Each sample was characterised by analytical methods such as gas chromatography-mass spectrometry (GC-MS). We then determined the radiocarbon ages of some of the samples …

With the continued adoption of genome‐scale data in evolutionary biology comes the challenge of adequately harnessing the information to make accurate phylogenetic inferences. Coalescent‐based methods of species tree inference have become common, and concatenation has been shown in simulation to perform well, particularly when levels of incomplete lineage sorting are low. However, simulation conditions are often overly simplistic, leaving empiricists with uncertainty regarding analytical tools. We use a large ultraconserved element data set (>3,000 loci) from rattlesnakes of the Crotalus triseriatus group to delimit lineages and estimate species trees using concatenation and several coalescent‐based methods. Unpartitioned and partitioned maximum …
