Instantiated Recoupling In Principals' Enactment Of Teacher Evaluations: Emotion Work And New Forms Of Ceremonial Conformity In Educational Institutions, Christopher P. Duncan, Judson G. Everitt
Instantiated Recoupling In Principals' Enactment Of Teacher Evaluations: Emotion Work And New Forms Of Ceremonial Conformity In Educational Institutions, Christopher P. Duncan, Judson G. Everitt
Sociology: Faculty Publications and Other Works
As accountability policies have proliferated and evolved in a number of organizational fields, recent scholarship in organizational sociology has paid close attention to the ways that accountability has forced tight coupling in a variety of organizations. Fewer recent studies examine efforts at ceremonial conformity that organizations may use to buffer internal practices from institutional pressures, or how organizations and their actors might attempt to engage in ceremonial conformity under newer accountability regimes. In this article, we examine how school principals enact state-mandated teacher evaluation policies with their teachers. To manage teachers' stress caused by the evaluations, we find that principals …
The Stories We Tell: Colorblind Racism, Classblindness, And Narrative Framing In The Rural Midwest, Teresa Irene Gonzales Phd, Elizabeth M. Thissell, Soumitira Thorat
The Stories We Tell: Colorblind Racism, Classblindness, And Narrative Framing In The Rural Midwest, Teresa Irene Gonzales Phd, Elizabeth M. Thissell, Soumitira Thorat
Sociology: Faculty Publications and Other Works
The stories we tell about ourselves and our communities have the power to impact perceptions of marginalized communities, both positively and negatively. Narratives affect how people view themselves, their town, and other members of their community and thus shape personal interactions, local culture, social situations, and even decisions about allocation of resources. When those stories are rooted in discursive frames—what we can understand as the links between ideology and narrative—they can also perpetuate and reify power inequities. Within rural America, local elites and residents alike use narratives and discursive framing to erase or exclude communities of color and, at times, …

Although many studies have focused on the importance of littering and (or) illegal dumping as a source of plastic pollution to freshwater, other relevant pathways should be considered, including wastewater, stormwater runoff, industrial effluent/runoff, and agricultural runoff. Here, we conducted a meta-analysis focused on these four pathways. We quantified the number of studies, amount and characteristics of microplastics reported, and the methods used to sample and measure microplastics from each pathway. Overall, we found 121 studies relevant to our criteria, published from 2014 to 2020. Of these, 54 (45%) quantified and characterized microplastics in discharge pathways. Although most focused on …

Bias Mitigation For Toxicity Detection Via Sequential Decisions, Lu Cheng, Ahmadreza Mosallanezhad, Yasin N. Silva, Deborah Hall, Huan Liu
Bias Mitigation For Toxicity Detection Via Sequential Decisions, Lu Cheng, Ahmadreza Mosallanezhad, Yasin N. Silva, Deborah Hall, Huan Liu
Computer Science: Faculty Publications and Other Works
Increased social media use has contributed to the greater prevalence of abusive, rude, and offensive textual comments. Machine learning models have been developed to detect toxic comments online, yet these models tend to show biases against users with marginalized or minority identities (e.g., females and African Americans). Established research in debiasing toxicity classifiers often (1) takes a static or batch approach, assuming that all information is available and then making a one-time decision; and (2) uses a generic strategy to mitigate different biases (e.g., gender and racial biases) that assumes the biases are independent of one another. However, in real …

In this paper, a series of experimental methods are presented explaining a new approach towards active foveated Computer Vision (CV). This is a collaborative effort between researchers at CONICET Mendoza Technological Scientific Center from Argentina, Argonne National Laboratory (ANL), and Loyola University Chicago from the US. The aim is to advance new CV approaches more in line with those found in biological agents in order to bring novel solutions to the main problems faced by current CV applications. Basically this work enhance Self-supervised (SS) learning, incorporating foveated vision plus saccadic behavior in order to improve training and computational efficiency without …
Unveiling Bacterial Hitchhikers In The Urobiome, Genevieve Baddoo
Unveiling Bacterial Hitchhikers In The Urobiome, Genevieve Baddoo
Master's Theses
Microbial communities of bacteria, viruses, and fungi form complex interactions in nature. However, our understanding of these communities is limited to those that can be cultured in the lab. Enhanced culture methods have enabled the isolation of numerous fastidious species from urinary tract, definitively proving that the urinary tract of asymptomatic individuals is not sterile. In working with these isolates, our group has observed several instances in which a “purified” isolate actually harbors more than one species. We refer to these additional members as bacterial hitchhikers, a term previously used to describe similar occurrences in soil communities. I hypothesized that …
“An Umbrella For All Things”: Black Daughter's Sexual Decisions And Paternal Engagement, Marquitta S. Dorsey
“An Umbrella For All Things”: Black Daughter's Sexual Decisions And Paternal Engagement, Marquitta S. Dorsey
Social Work: School of Social Work Faculty Publications and Other Works
Objective: The purpose of this article is to highlight the value of Black fathers to the sexual decision-making processes among Black adolescent and young adult daughters. Background: Various contextual factors, such as fewer sexual health resources in poorer communities and federal funding cuts to family planning service agencies, ultimately contribute to the sexual health decision-making of adolescent young women and may be linked to sexual health disparities among Black adolescent women. Recent studies have reported the protective nature of a Black father’s engagement to be beneficial to the behavioral outcomes of adolescent daughters. Method: Findings from 17 semistructured interviews conducted …

This paper explores the strategies that staff at two refugee-serving organizations found helpful in mitigating their increased distress from negative political rhetoric aimed at their clients. Results point to the importance of organizational acknowledgement of the distress. Additionally, staff perceived that intentionally focused organizational interventions can mitigate the emotional impacts of negative rhetoric. Finally, strategies employees used to lessen their distress and regain a sense of efficacy included recommitment to the mission, advocacy for refugees among family and friends, strong reliance on religious faith in coping, and an avoidance of the rhetoric by decreasing engagement with news and social media.
Dbsnap 2: New Features To Construct Database Queries By Snapping Blocks, Yasin N. Silva, Alexis Loza, Humberto Razente
Dbsnap 2: New Features To Construct Database Queries By Snapping Blocks, Yasin N. Silva, Alexis Loza, Humberto Razente
Computer Science: Faculty Publications and Other Works
Block-based environments for creating computer programs have become very useful learning tools in computer science as they enable focusing on the logic of a program rather than on its syntactical details. While most block-based environments support conventional (imperative) instructions, a few tools have been proposed to create database queries. One of these tools is DBSnap, a highly dynamic and open-source tool to create database query trees by dragging and connecting visual blocks representing datasets and database operators. In this paper, we introduce DBSnap 2, an extension of DBSnap that provides a set of improvements to facilitate the creation of simple …

Dbsnap-Eval: Identifying Database Query Construction Patterns, Yasin N. Silva, Alexis Loza, Humberto Razente
Computer Science: Faculty Publications and Other Works
Learning to construct database queries can be a challenging task because students need to learn the specific query language syntax as well as properly understand the effect of each query operator and how multiple operators interact in a query. While some previous studies have looked into the types of database query errors students make and how the availability of expected query results can help to increase the success rate, there is very little that is known regarding the patterns that emerge while students are constructing a query. To be able to look into the process of constructing a query, in …

A Labeled Dataset For Investigating Cyberbullying Content Patterns In Instagram, Mara Hamlett, Grace Powell, Yasin N. Silva, Deborah Hall
Computer Science: Faculty Publications and Other Works
As online communication continues to become more prevalent, instances of cyberbullying have also become more common, particularly on social media sites. Previous research in this area has studied cyberbullying outcomes, predictors of cyberbullying victimization/perpetration, and computational detection models that rely on labeled datasets to identify the underlying patterns. However, there is a dearth of work examining the content of what is said when cyberbullying occurs and most of the available datasets include only basic labels (cyberbullying or not). This paper presents an annotated Instagram dataset with detailed labels about key cyberbullying properties, such as the content type, purpose, directionality, and …
