From A Bag Lunch To A Buffet: A Case Study Of A Low-Income African American Academy’S Vision Of Promoting College And Career Readiness In The United States, Edward C. Fletcher Jr., Erik M. Hines, Donna Y. Ford, James L. Moore Iii

Journal of College Access

The purpose of this research study was to examine the ways in which stakeholders at a low-income, predominantly African American STEAM academy implement initiatives that support the college and career readiness of their students. We found that a shift in leadership efforts to ensure that academy students were prepared to be both college and career ready provided equity and access to a quality and individualized curriculum through the implementation of career academies. As a result, stakeholders believed that students were more included, valued, and engaged in the school.

Automating Fda Regulation, Mason Marks

Duke Law Journal

In the twentieth century, the Food and Drug Administration (“FDA”) rose to prominence as a respected scientific agency. By the middle of the century, it transformed the U.S. medical marketplace from an unregulated haven for dangerous products and false claims to a respected exemplar of public health. More recently, the FDA’s objectivity has increasingly been questioned. Critics argue the agency has become overly political and too accommodating to industry while lowering its standards for safety and efficacy. The FDA’s accelerated pathways for product testing and approval are partly to blame. They require lower-quality evidence, such as surrogate endpoints, and shift …

Algorithm V. Algorithm, Cary Coglianese, Alicia Lai

Duke Law Journal

Critics raise alarm bells about governmental use of digital algorithms, charging that they are too complex, inscrutable, and prone to bias. A realistic assessment of digital algorithms, though, must acknowledge that government is already driven by algorithms of arguably greater complexity and potential for abuse: the algorithms implicit in human decision-making. The human brain operates algorithmically through complex neural networks. And when humans make collective decisions, they operate via algorithms too—those reflected in legislative, judicial, and administrative processes. Yet these human algorithms undeniably fail and are far from transparent. On an individual level, human decision-making suffers from memory limitations, fatigue, …

Modeling Through, Ryan Calo

Duke Law Journal

Theorists of justice have long imagined a decision-maker capable of acting wisely in every circumstance. Policymakers seldom live up to this ideal. They face well-understood limits, including an inability to anticipate the societal impacts of state intervention along a range of dimensions and values. Policymakers see around corners or address societal problems at their roots. When it comes to regulation and policy-setting, policymakers are often forced, in the memorable words of political economist Charles Lindblom, to “muddle through” as best they can.

Powerful new affordances, from supercomputing to artificial intelligence, have arisen in the decades since Lindblom’s 1959 article that …

The Translation Of Personal Pronouns In French Discourses Into Indonesian, Sajarwa Sajarwa

Bahasa dan Seni: Jurnal Bahasa, Sastra, Seni, dan Pengajarannya

Translation is the transfer of a message from a source-language text into an equivalent target-language text. Cultural differences between a source language and a target language always leave marks on a translation process. Language as part of culture influences the minds of its speakers, especially translators. French literary texts (as source texts) and their Indonesian translations (target texts) can provide examples of the differences between the reasoning process of French literary writers and that of Indonesian translators, particularly in the translation of pronouns with this topic being the focus of this present study. By carefully investigating how pronouns are translated …

Journal of Extension

Traditional delivery of Extension programming changed overnight in March 2020, when the COVID-19 outbreak forced switching traditional methods to virtual delivery. Extension professionals across South Carolina quickly adapted to online delivery. Concerns over instructor preparedness to use online tools, including functions to assure accessibility, did arise. Findings from this non-experimental, descriptive research study suggested Extension professionals used online tools (primarily Zoom). The majority were not comfortable using many of the features that would enhance instruction, including polling, file transfer, and live-streaming media platforms. Additionally, Microsoft Word and PowerPoint skills to assure accessibility for clientele were lacking.

Introduction: The clinical translation of biofluid markers for dementia requires validation in diverse cohorts. The study goal was to evaluate if blood biomarkers reflecting diverse pathophysiological processes predict disease progression in Mexican American adults.

Methods: Mexican American adults (n = 745), 50 years of age and older, completed annual assessments over a mean of 4 years. Serum collected at baseline was assayed for total tau, neurofilament light (NFL), ubiquitin carboxyl‐terminal hydrolase LI, glial fibrillary acidic protein (GFAP), soluble cluster of differentiation 14 (sCD14), and chitinase‐3‐like protein 1 (YKL‐40).

Results: Higher GFAP and NFL were associated with global …

Hot-Headed Peckers: Thermographic Changes During Aggression Among Juvenile Pheasants ( Phasianus Colchicus ), Sophia Knoch, Mark A. Whiteside, Joah R. Madden, Paul E. Rose, Tim W. Fawcett

School of Biological and Marine Sciences

In group-living vertebrates, dominance status often covaries with physiological measurements (e.g. glucocorticoid levels), but it is unclear how dominance is linked to dynamic changes in physiological state over a shorter, behavioural timescale. In this observational study, we recorded spontaneous aggression among captive juvenile pheasants ( Phasianus colchicus ) alongside infrared thermographic measurements of their external temperature, a non-invasive technique previously used to examine stress responses in non-social contexts, where peripheral blood is redirected towards the body core. We found low but highly significant repeatability in maximum head temperature, suggesting individually consistent thermal profiles, and some indication of lower head temperatures …

IntroductionNitrate supplementation in the form of beetroot juice (BRJ) ingestion has been shown to improve exercise tolerance during acute hypoxia, but its effect on exercise physiology remains unstudied during sustained terrestrial high altitude exposure. We hypothesized that performing exercise at high altitude would lower circulating nitrate and nitrite levels and that BRJ ingestion would reverse this phenomenon while concomitantly improving key determinants of aerobic exercise performance.MethodsTwenty seven healthy volunteers (21 male) underwent a series of exercise tests at sea level (SL, London, 75 m) and again after 5–8 days at high altitude (HA, Capanna Regina Margherita or “Margherita Hut,” 4,559 …

What And Who Has Determined Adoption? A Study On Improved Forage Technologies In Colombia From An Agricultural Innovation System (Ais) Perspective, K. Enciso, N. Triana, M. Díaz, S. Burkart

IGC Proceedings (1977-2023)

The complex process behind the adoption of improved forages in Colombia remains largely unexplored. Despite governmental and scientific efforts to promote and disseminate the implementation of improved forages for the sake of sustainable livestock production, local livestock producers continue to extensively use native species and adoption rates of more efficient forages remain low. This study explores the dynamics behind the development and diffusion of improved forage technologies in Colombia, from the 1960's to the present through an Agricultural Innovation Systems (AIS) perspective. Here we map the agents involved, classify the roles they exerted over time and reconstruct the historical context …

Smallholder Dairy Farmers In The Peruvian Andes Fulfilling The Role Of Extension Agents, C. S. Pinares-Patino, J. Manhire, R. Garcia Ticllacuri, J. L. Bernal Madrid, V. M. Velez Marroquin

IGC Proceedings (1977-2023)

Dairy farming in the Peruvian Andes is mostly undertaken by smallholder farmers (4-6 cows/family) and of relatively recent development. In fact, over the last 2 decades dairy farming at high altitudes (3,500‒4200 masl) has grown rapidly, replacing the camelids and sheep farming that once predominated. Dairying growth has been catalysed by subsides from state and private organizations. It promotes high input systems based on feedlot technology. Compared to sheep and camelids farming, dairying at the Andes does not have yet an inherent local/indigenous knowledge associated to it. High altitude Andean ecosystems pose many constraints for dairy farming (hypoxia and high …

Alcoholism is one of the most common diseases that can lead to the development of several chronic diseases including steatosis, and cognitive dysfunction. Statins are lipid-lowering drugs that are commonly prescribed for patients with fatty liver diseases; however, the exact effect of statins on cognitive function is still not fully understood. In the present study, we have investigated the molecular and microscopic basis of cognitive impairment induced by alcohol and/or Atorvastatin (ATOR) administration to male Wistar albino rats and explored the possible protective effect of acetylsalicylic acid (ASA). The biochemical analysis indicated that either alcohol or ATOR or together in …

Challenges In Gluten Analysis: A Comparison Of Four Commercial Sandwich Elisa Kits, Plaimein Amnuaycheewa, Lynn Niemann, Richard E. Goodman, Joseph L. Baumert, Steve L. Taylor

Department of Food Science and Technology: Faculty Publications

Gluten is composed of prolamin and glutelin proteins from several related grains. Because these proteins are not present in identical ratios in the various grains and because they have some differences in sequence, the ability to accurately quantify the overall amount of gluten in various food matrices to support gluten-free labeling is difficult. Four sandwich ELISAs (the R-Biopharm AG R5 RIDASCREEN®, the Neogen Veratox® R5, the Romer Labs AgraQuant® G12, and the Morinaga Wheat kits) were evaluated for their performance to quantify gluten concentrations in various foods and ingredients. The Morinaga and AgraQuant® G12 tests yielded results comparable to the …

Decellularized Articular Cartilage Microgels As Microcarriers For Expansion Of Mesenchymal Stem Cells, Esmaiel Jabbari, Azadeh Sepahvandi

Faculty Publications

Conventional microcarriers used for expansion of human mesenchymal stem cells (hMSCs) require detachment and separation of the cells from the carrier prior to use in clinical applications for regeneration of articular cartilage, and the carrier can cause undesirable phenotypic changes in the expanded cells. This work describes a novel approach to expand hMSCs on biomimetic carriers based on adult or fetal decellularized bovine articular cartilage that supports tissue regeneration without the need to detach the expanded cells from the carrier. In this approach, the fetal or adult bovine articular cartilage was minced, decellularized, freeze-dried, ground, and sieved to produce articular …

Pastoralists’ Perception Of Poverty: A Case Of The Somali And Turkana Of Northern Kenya, W. P. Watete, Kogi-Makau

IGC Proceedings (1977-2023)

Poverty is a complex phenomenon, without a single definition or standard methods of reducing it. Income based methods of assessing poverty have been shown to have limitations that undermine their application in measuring and attacking poverty among pastoral households. Stages of progress method of poverty assessment was used to assess poverty among pastoral households in Turkana and Mandera Counties of Northern Kenya. Three hundred and three hundred and fifty-four households in Mandera and Turkana Counties respectively were sampled across three different livelihood zones: pastoral, agro-pastoral and off-farm. Accumulation of livestock was regarded as a key indicator of wealth among pastoral …

Pastoralist Conservation: Local Ecological Knowledge And Collective Action For Grassland Conservation In Sierra De Segura (Spain), P. Sanosa-Cols, F. Ravera, F. Dominguez, M. Ventura

IGC Proceedings (1977-2023)

Even if Pastoralism is not practised anymore by a majority of families in the Sierra de Segura (south-eastern Andalusia, Spain), it is still considered a paradigmatic way of life and management of its highlands and a key cultural heritage deeply rooted in local identity. In this article we explore two pastoral communities of this region, Santiago and Pontones, with their body of situated knowledge of the territory and natural resources, which helps pastoralists to organize their livelihoods, while requiring collective organization to manage access to grasslands. Through an ethnographic research based on participant observation and in-depth interviews, we explore the …

Intensification Of Pastoralism As A Driver Of Degradation In The Algerian Steppe, S. Bencherif, P. Manzano

IGC Proceedings (1977-2023)

Land degradation linked to pastoralism use has been a worldwide concern for decades. A biological approach has often been use to understand such phenomena, usually disregarding economic and social factors. Radical transformations of pastoralism at the Algerian steppe constitute a good case study to provide an integrated understanding and to better orient development in other pastoralist areas across the world. Different actions by the public sector since the 1960s, as well as the land legislation adopted and the strong agricultural subventions during 2000-2010, have favored a massive conversion of land and resource management. This translates into conversion of many pastures …

Perceptions Of Rangeland Degradation In The Peruvian Altiplano Dry Puna And Implications, C. Turin, J. Gilles

IGC Proceedings (1977-2023)

The Peruvian altiplano’s dry puna is the main feed source for specialized alpaca pastoralist systems. Experts argue that rangelands are severely degraded and have formulated policies and programs to address this. However, these programs have had little success. This paper presents a qualitative case study of the perceptions of rangeland degradation held in three Aymara communities, by range scientists of academia, personnel of NGOs operating in the region and by government officers. We found that each of these groups had distinct views of the level and causes of degradation in the region. Differences in perceptions undermined cooperation and trust between …

Endangered Sustainable Innovation: Indigenous Milk Hygiene And Preservation Techniques By Maasai Too Valuable To Lose, J. Y. Laffa, C. R. Mcculloch, D. Schoder

IGC Proceedings (1977-2023)

The indigenous Parakuyo Maasai communities of Tanzania are traditional pastoralists who depend on fresh cow’s milk as a staple food. However, the arid climate and a lack of clean water challenge milk production and conventional milk hygiene practices.

By conducting informational interviews in eight Parakuyo Maasai regions and 13 districts of Tanzania we sought to identify the key indigenous plants preferred and establish their traditional manner of use. A semi-structured questionnaire was designed to: (i) determine the plants used, (ii) the parts used, (iii) methods of preparation and utensil smoking, (iv) therapeutic applications and associated health benefits of these plants, …

Gender: A Useful Category Of Analysis For Tanzanian Researchers, Florence Wenzek

Journal of International Women's Studies

This article enriches reflections on the circulation of the concept of gender in the Global South by looking at the transformations of Tanzanian research on gender in education between the 1970s and the early 1990s. A close reading of the texts shows how the concept of gender has been used in this field of study since 1990; it considers variations depending on authors and their positioning. Comparing this with the writings of the 1970s and 1980s, when no one used the concept, reveals how it contributed to epistemological change. The article also reflects on the respective role of local factors …
