Decadal Changes In Ground-Layer Plant Communities Reflect Maple Dieback And Earthworm Invasion In National Forests In The Lake Superior Region, Usa, Tara Bal, Manuel Eduardo Anderson, Mattison E. Brady, Julia I. Burton, Christopher R. Webster

Michigan Tech Publications

Northern hardwood forests of the Lake Superior region face a series of novel disturbance pressures including canopy dieback. Previous studies have linked regional sugar-maple (Acer saccharum) canopy dieback to introduced earthworms, which may have coinciding impacts on the ground-layer plant community. Dieback–earthworm interactions may lead to important longer-term changes in forest structure and function, but these relationships but have not been characterized. We sampled ground-layer plant communities in five national forest units in Michigan, Wisconsin, and Minnesota in 2010, and again just over a decade later in 2021. Non-metric multidimensional scaling ordination and indicator species analysis were used to assess …

Exploring The World Of Medical Exoskeleton Robots: A Classification Guide, Javlonbek Rakhmatillaev, Vytautas Bučinskas

Technical science and innovation

This article describes the classification of exoskeletons. This classification is based on the use of exoskeletons in the medical field, shape, power source, generation, parts related to the human body, structural material, and control forms based on sensor and actuator devices. In addition, examples of each category are given. The main goal is to comprehensively evaluate medical exoskeletons, pay special attention to their functions and goals, conduct scientific research, and further develop these devices. As a result, a completely new type of classification of medical exoskeletons was developed. The developed new type of classification serves as an important guide in …

Topology Across Scales On Heterogeneous Cell Data, M. Torras-Pérez, Iris Yoon , '13, P. Weeratunga, L.-P. Ho, H. M. Byrne, U. Tillmann, H. A. Harrington

Mathematics & Statistics Faculty Works

Multiplexed imaging allows multiple cell types to be simultaneously visualised in a single tissue sample, generating unprecedented amounts of spatially-resolved, biological data. In topological data analysis, persistent homology provides multiscale descriptors of “shape" suitable for the analysis of such spatial data. Here we propose a novel visualisation of persistent homology (PH) and fine-tune vectorisations thereof (exploring the effect of different weightings for persistence images, a prominent vectorisation of PH). These approaches offer new biological interpretations and promising avenues for improving the analysis of complex spatial biological data especially in multiple cell type data. To illustrate our methods, we apply them …

Technical science and innovation

This study looks at the serious problem of plastic waste causing pollution around the world. It focuses on how little polystyrene foam gets recycled. As a better option, the study checks out making and describing composite stuff made from wood waste, like poplar and paulownia sawdust. These natural fillings have cellulose, hemicellulose, and lignin, which let them stick well to plastic polymers like polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC).

The composite materials were made using hot pressing. They were tested to see how dense, hard, strong, and impact-resistant they were, using GOST standards. The tests showed that adding …

China’S Turn To Domestic-Led Growth: Replacing Consumption Taxes With Land Taxes?, Yilin Hou, Michael Kumhof, Lei Shao

Center for Policy Research

As part of its turn towards domestic-led growth China plans to stimulate consumption, including through a reduction in consumption taxes. We compare two model-based scenarios in which the revenue losses from lower consumption taxes are replaced by higher income taxes or higher land taxes. The model is carefully calibrated to recent Chinese data, including detailed fiscal data. We find that higher income taxes lead to significant losses in output and incomes, while higher land taxes lead to significant gains. These gains are increasing in the share of land in net wealth, a statistic for which better data would be invaluable.

Finessing A Medical Expert’S Qualifications: From Professional Communities’ Boundaries To Personal Character, Patrick Garon-Sayegh

Osgoode Hall Law Journal

This article examines the kinds of arguments that can be made in debates regarding whether or not an expert is properly qualified to critique the work or opinions of another expert. Since these debates routinely occur in both legal and political arenas, a more fine-tuned sense of their argumentative dynamics can be fruitful for reasoning through them. This article is built around the analysis of a decision which concerned the admissibility of a physician’s testimony on the medical standard of care in a malpractice case. A detailed parsing of the arguments in that decision lays the groundwork for a theoretical …

Against Settlement In Transnational Business And Human Rights Litigation, Hassan M. Ahmad

Osgoode Hall Law Journal

In “Against Settlement,” Owen Fiss argued that settlement may not always be the optimal result of civil suits, particularly those that involve novel or ambiguous areas of law or ostensible power imbalances. That work spurred a range of scholarship around the merits and demerits of settlement. And although the settlement versus litigation debate is now almost four decades old, its currency persists in common law systems in which courts are, at times, called upon to expand or even re-envision doctrines or procedural rules. This article revisits that debate. It applies “Against Settlement” to transnational business and human rights litigation that …

Crim-Eviction: Eviction And Social Control At A Residential Tenancies Tribunal, Sarah Buhler

Osgoode Hall Law Journal

Because eviction from rental housing can lead to highly negative outcomes, including homelessness, trauma, neighbourhood instability, and deepening inequities, it is important to understand the reasoning processes employed by tribunals when they wield the power of eviction. This article conducts a critical reading of decisions of the Office of Residential Tenancies, Saskatchewan’s residential tenancies tribunal, that deal specifically with urgent landlord applications for immediate eviction based on tenant behaviours that are alleged to be criminal, illegal, frightening, or dangerous. Coining the term “crim-eviction” to help describe this category of decisions, the article identifies that residential tenancies tribunals like the Office …

Reckoning With Queer History: The Canadian “Lgbt Purge” Case And The Limits Of Forgiveness, Daniel Del Gobbo

Osgoode Hall Law Journal

The Canadian government has a long history of regulation, exploitation, and violence against lesbian, gay, bisexual, trans, queer, and two-spirit (LGBTQ2S+) people. One of the most painful chapters in this history is the “LGBT Purge,” a term that refers to the expulsion of LGBTQ2S+ service members and employees from the Canadian Armed Forces, Royal Canadian Mounted Police, and Federal Public Service between 1955 and 1992. The LGBT Purge was the subject of a class action lawsuit filed in 2017 that resulted in a settlement agreement in 2018. On a parallel track to the settlement, Prime Minister Justin Trudeau issued a …

Sex Discrimination, Assimilation, And Austerity: The Untold Story Of Canada’S Indian Act, 1975-1985, Genevieve Renard Painter

Osgoode Hall Law Journal

This article is about the misunderstood history of a Canadian law for determining Indian status, the decades-long struggle to remedy sex discrimination in the law, and the significance of judges writing history. Since before Canada’s confederation until amendments to the Indian Act in 1985, Indian women, unlike Indian men, lost their Indian status if they married non-Indians. Even with the 1985 amendments, the law still disadvantaged people who traced their Indian status along the female line. Facing a challenge to the law based on sex discrimination, the government argued that the enduring disadvantage to women was the only way to …

Doing Away With Racial Profiling In Policing Without Doing Away With The Rule Of Law, François Tanguay-Renaud

Osgoode Hall Law Journal

Since the turn of the millennium, Canadian appellate courts have been investing increasingly systematic efforts in demystifying and curtailing racial profiling in policing. These judicial efforts have so far been focused on the application of the legal criteria for arrest and detention as well as their regulation under section 9 of the Canadian Charter of Rights and Freedoms. In this article, I contend that this unidimensional approach is unsound and outline a corrective path forward. First, I argue that the prevailing judicial understanding of what racial profiling is and how it affects the lawfulness of arrests and detentions has the …

Disambiguating The Wrongs Of Racial Profiling In Policing And Championing Their Structural Remediation: A Reply, François Tanguay-Renaud

Osgoode Hall Law Journal

CANADIAN LAW JOURNALS have never been known for going out of their way to facilitate direct conversations between legal scholars working on cognate issues. However, if there is anything to the old liberal adage that the truth is more likely to emerge from the civil yet robust debating of competing ideas, the lack of opportunities for holders of rival views to respond, in real time, to each other’s arguments is deplorable. Therefore, I wish to commend the Osgoode Hall Law Journal for convening this timely scholarly exchange on the problematic phenomenon of racial profiling in Canadian policing and, more specifically, …

Racial Profiling And The Rule Of Law: A Reply, Terry Skolnik, Jeanne Mayrand-Thibert, Fernando Belton

Osgoode Hall Law Journal

THIS VOLUME OF THE OSGOODE HALL LAW JOURNAL (OHLJ) contains two articles—and two replies—that explore racial profiling and the law. This academic exchange comes at a crucial moment. In Attorney General of Québec v Luamba (“Luamba”), the Court of Appeal of Quebec affirmed that the statutory police power to conduct roving traffic stops is unconstitutional because it results in arbitrary detentions and unconstitutional discrimination, neither of which were justifiable in a free and democratic society.

The Law Of Racial Profiling, Terry Skolnik, Jeanne Mayrand-Thibert, Fernando Belton

Osgoode Hall Law Journal

Racial profiling is one of the most enduring problems in policing. Yet it remains largely under-theorized, which generates important theoretical and practical implications. Racial profiling tends to be construed as an arbitrary detention rather than a form of unconstitutional discrimination. For this reason, the section 15 Charter right to equality plays little to no role in most leading cases on racial profiling. The legal framework that governs racial profiling lacks clarity and can be applied inconsistently. And the remedial landscape associated with racial profiling claims has evolved minimally. This article advances a novel approach to racial profiling that addresses these …

Tulp3 Quantitative Alleles Titrate Requirements For Viability, Brain Development, And Kidney Homeostasis But Do Not Suppress Zfp423 Mutations In Mice, Corinne A. Mccoy, Dorothy Concepcion, Mark G. Mezody, Raquel Lara, Ojas Deshpande, Catherine Liang, Renee Long, Bruce A. Hamilton

School of Medicine Publications

Tubby-like protein 3 (TULP3) regulates receptor trafficking in primary cilia and antagonizes SHH signaling. Tulp3 knockout mice are embryonic lethal with developmental abnormalities in multiple organs, while tissue-specific knockouts and viable missense alleles cause polycystic kidney disease. Human patients with TULP3 mutations present with variable, but often multi-organ fibrotic disease. We previously showed that mouse and human Tulp3 expression is negatively regulated by ZNF423, which is required for SHH sensitivity in some progenitor cell models. The level of TULP3 function required to prevent mutant phenotypes has not been known. Here we report a Tulp3 quantitative allelic series, designed …

Reverberations Of 2020: The Role Of The U.S. Racial Reckoning On Multicultural Engagement In Counseling, Dr. Donya D. Wallace, Dr. Teceta Tormala, Dr. Shreya Vaishnav, Wen Guo

Journal of Counselor Preparation and Supervision

The racial reckoning of 2020 and 2021 had profound effects on people. This study uses a retrospective design to examine differences in critical consciousness prior to 2020 and contemporarily among counseling students and professionals and whether critical consciousness predicts multicultural competence. Participants reported their current level of multicultural competence, and pre-2020 (retrospective) and current (contemporary) levels of critical reflection, critical motivation, critical action, and race-based critical consciousness. Participants reported higher levels on the contemporary critical consciousness measures than their retrospective assessments, suggesting that the high-impact events of 2020 raised their critical consciousness. There was no relationship between the critical consciousness …

Understanding Mental Health From A Learning Perspective, Liz Norell

Events

We hear plenty of alarms about students’ mental health challenges, with professors often feeling like they must become therapists and coaches in addition to instructors. In this workshop, we’ll talk about how mental health impacts our students’ abilities to engage in our classes and absorb class material/readings. Without requiring instructors to take on the emotional labor of managing students’ mental health, we’ll discuss things instructors can do to improve student learning by examining and reframing our pedagogical choices. Attendees will leave with ideas on how to craft their class sessions to improve student attention, engagement, and learning.

Learning About Stability Of Risk Preferences, Levon Barseghyan, Francesca Molinari, Joshua C. Teitelbaum

Georgetown Law Faculty Publications and Other Works

Classical theories posit that risk preferences are stable across decision contexts. Two branches of empirical literature assess this claim. Structural approaches examine within-person consistency of model-based estimates of risk aversion, while “model-free” approaches examine within-person correlations of risky choices. We elucidate the latent structure underlying the model-free approach. Using this structure, we develop a new approach to assessing preference stability that has stronger testable implications, and we partially identify features of stability and heterogeneity of risk preferences. Our study illustrates a general principle: partial identification through minimal assumptions grounded in economic theory robustly bridges fully structural and model-free methods.
