Knowledge Commons Past, Present, And Future, Michael J. Madison

Lewis & Clark Law Review

The project now known as Governing Knowledge Commons, or GKC, was launched more than 15 years ago on the intuition that skepticism of intellectual property law and information exclusivity was grounded in anecdote and ideology rather than in empiricism. Structured, systematic, empirical research on mechanisms of knowledge sharing was needed. GKC aimed to help scholars produce it. Over multiple books, case studies, and other work, the scope of GKC has expanded considerably, from innovation to governance; from invention and creativity to data, privacy, and markets; and from social dilemmas focused on things to governance strategies directed to communities and collectives. …

Governor Kate Brown Of Oregon’S Historic Use Of Clemency: Using Clemency Exactly As It Was Intended, Mark Cebert, Aliza B. Kaplan

Lewis & Clark Law Review

In Oregon, executive clemency is among the most expansive, yet historically underused, power a governor possesses. Yet, across her two terms as Oregon’s 38th governor, Governor Kate Brown exercised her power of executive clemency a record 61,777 times, dwarfing the clemency use of her predecessors and her contemporaries in other states. Governor Brown’s proactive approach to clemency presents a model for executive involvement in criminal justice reform and aligns with her beliefs of a redemptive and rehabilitative criminal legal system.

In this Article, we examine Governor Brown’s use of clemency, analyzing what her stated and implied rationales reveal about her …

Cognitive Content Moderation: Freedom Of Thought And The First Amendment Right To Receive Subconscious Information, Mason Marks

Scholarly Publications

In the television series Severance, employees of Lumon Industries receive brain implants that divide their memories of work and home life. When employees arrive at work, implants block access to memories of the outside world and unlock memories formed on the job. By manipulating the flow of information in employees' brains, Lumon engages in what this Article calls cognitive content moderation. Though Severance is science fiction, emerging technologies, including drugs and electronic devices, promote cognitive content moderation by influencing thought, memory, and perception. Constitutional law is unprepared. To clarify freedom of thought and make it more useful, this Article presents …

Stress Biology: Complexity And Multifariousness In Health And Disease, Emily M. Sontag

Biological Sciences Faculty Research and Publications

Preserving and regulating cellular homeostasis in the light of changing environmental conditions or developmental processes is of pivotal importance for single cellular and multicellular organisms alike. To counteract an imbalance in cellular homeostasis transcriptional programs evolved, called the heat shock response, unfolded protein response, and integrated stress response, that act cell-autonomously in most cells but in multicellular organisms are subjected to cell-nonautonomous regulation. These transcriptional programs downregulate the expression of most genes but increase the expression of heat shock genes, including genes encoding molecular chaperones and proteases, proteins involved in the repair of stress-induced damage to macromolecules and cellular structures. …

Synthesis And Evaluation Of 1,3-Disubstituted Imidazolidine-2,4,5-Triones As Inhibitors Of Pyruvate Carboxylase, Nicholas O. Schneider, Keandra Gilreath, Niel M. Henriksen, William A. Donaldson, Subhabrata Chaudhury, Martin St. Maurice

Biological Sciences Faculty Research and Publications

Substituted imidazolidinetriones (IZTs) have been identified as potent inhibitors of pyruvate carboxylase (PC) through an in silico screening approach. Alkyl 2-(2,4,5-trioxo-3-substituted imidazolidin-1-yl)acetates (6i–6r) are the most potent of the series, with IC50 values between 3 and 12 μM, and several IZTs demonstrate high passive permeability across an artificial membrane. IZTs are mixed-type inhibitors with respect to pyruvate and noncompetitive with respect to ATP. This class of inhibitors appears to be selective for PC. Inhibitors in the IZT series do not inhibit the metalloenzymes human carbonic anhydrase II and matrix metalloprotease-12, and they do not inhibit the related biotin-dependent enzyme, guanidine …

Ableist Microaggressions, Disability Characteristics, And Nondominant Identities, Melissa Deroche, Lee Za Ong, Jennifer M. Cook

College of Education Faculty Research and Publications

Microaggressions are commonplace overt and covert forms of discrimination that convey disparaging messages to individuals who hold marginalized identities, including people with disabilities (PWD). Although PWD are a prevalent nondominant identity group in the United States, little is known about the occurrence of ableist microaggressions in this culturally diverse community, including how ableist microaggressions are experienced based on disability characteristics and other nondominant identities. A sample consisting of 201 PWD completed an electronic survey that examined the occurrence of ableist microaggressions based on visibility of disability, type of disability, and nondominant sociocultural identities. We found that PWD have a moderate …

Mansoura Journal of Dentistry

Objective: To assess the root canal anatomy and root morphology of mandibular third molars (MTMs) in the Egyptians using cone beam computed tomography (CBCT). Methods: A total of 338 CBCT scans of mandibular third molars (MTMs) were collected and evaluated regarding the related root(s) number and root canal configuration. Statistical analysis highlighted differences between different categories and their prevalence among genders and sides (significance level was set at p < 0.05). Data were presented as frequency and percentage values and were analyzed using a chisquare test followed by pairwise comparisons utilizing multiple Fisher’s exact tests with Bonferroni correction. The significance level was set at p < 0.05 within all tests. Results: A total of 338 MTMs [186 (55%) from male patients, 152 (45%) from female patients] from 279 patients (151 male and 128 female) were evaluated. The majority (82.84%) of the studied MTMs had two roots. single-, triple-, and quadruple-rooted MTMs were less common than double-rooted MTMs, accounting for 10.1%, 5.33%, and 1.18% of the sample, respectively. Regarding root canal anatomy, Vertucci type I was the most seen morphology (61% of all MTMs roots mostly in distal roots (42.41%), followed by Vertucci type III (13.08%). The chi-square test showed no significant difference between males and females (p=0.36) or between the right side and left sides (p=0.691) regarding the number of roots. Conclusion: Within the limitations of the present study, the findings conclude significant variability in the root and root canal anatomy of mandibular third molars (MTMs) within the Egyptian sub-population.

Tsetse flies and trypanosomosis significantly impact bovine production and human health in sub-Saharan Africa, exacerbating underdevelopment, malnutrition, and poverty. Despite various control strategies, long-term success has been limited. This study evaluates the combined use of entomopathogenic fungi (EPF) and the sterile insect technique (SIT) to combat tsetse flies. Eleven EPF isolates were tested against teneral males of Glossina pallidipes, focusing on mortality rates, radial growth, and impacts on fly fitness. Temperature effects on conidial growth, sporulation, and spore yield of SIT-compatible/tolerant strains were also assessed. The fungal isolates significantly influenced mortality rates in both unirradiated and irradiated (SIT-treated) males (p <  0.0001). Metarhizium anisopliae strains ICIPE 20, ICIPE 32, ICIPE 41, ICIPE 62, ICIPE 78, and Beauveria bassiana ICIPE 603 showed higher SIT compatibility/tolerance with LT50 values of 11–30 days, compared to other more virulent isolates with LT50 values of 4–9 days. Temperature significantly affected the radial growth of SIT-compatible EPF strains (p <  0.0001), with M. anisopliae ICIPE 78 exhibiting the fastest conidia growth at 25°C. Spore yield varied significantly across temperatures (15–40°C), and the thermal range for conidia germination of SIT-compatible strains was 8.1–45.4°C, with an optimal range of 26.7–31.1°C. Moreover, infected unirradiated females and irradiated males (donors) successfully transmitted conidia to untreated flies (receivers) without significant differences in survival rates (p = 0.6438) and no observed sex dimorphism. Our findings highlight the potential of combining EPF and SIT as a novel dual approach that could effectively and synergistically suppress tsetse fly populations.

All Peer-Reviewed Publications

Potato production in East Africa is seriously impacted by the potato cyst nematode (PCN), Globodera rostochiensis, where it has been recorded in at least three countries. In Kenya, it is widespread in all major potato-growing regions, often at very high densities. Consecutive cropping of potato on the same land and a sub-tropical climate have influenced PCN biology. For example, unusually large cysts have been regularly recovered. We have analysed the biological properties of these ‘giant cysts’. The giant cysts contained more eggs than those recovered from UK fields. Egg size did not differ from UK populations and there was no …

Investor-State Climate Litigation: Could International Investment Law Help To Protect The Climate?, Dr. Andreas Buser

Indian Journal of International Economic Law

Climate Protection and International Investment Law have an ambiguous relationship. Whereas some scholars highlight that investment Law could help in protecting green investments many commentators depict investment protection as an obstacle to States’ climate mitigation policies. This article seeks to go beyond that limited dichotomy in assessing whether investment law could be a tool for investors to argue for more, rather than less climate protection. In particular, full protection and security clauses may well be interpreted to contain due diligence obligations to protect climate sensitive investments against effects of climate change. Moreover, if States postpone climate protection to a time, …

Wto Law And Environmental Processes And Production Methods (Ppms): A Deconstruction, Irene Musselli

Indian Journal of International Economic Law

In principle, WTO members can adopt PPM measures to protect the environment, provided certain conditions are met to prevent the misuse of these measures for protectionist purposes. In practice, the judicial review of such measures in the WTO context is punctuated by practical difficulties, and is fraught with intractable uncertainty: most PPM regulations that were challenged passed on principle but failed on specific details related to the dispute at hand. This article aims to contribute to the PPM discussion by providing critical and deconstructive perspectives on trade law. It argues that the challenges in assessing WTO compliance of PPMs stem …
