Herbage Characteristics As Affected By The Canopies Of Dominant Trees In A Savanna Of Southern Mozambique, James P. Muir, A. Alage, Inacio C. Maposse

IGC Proceedings (1977-2023)

This study surveyed the species composition, forage yield and forage nitrogen concentration of the herbaceous layer 50, 100 and 200% of the canopy radius from the trunks of many-stemmed false thorn, knob thorn, scented thorn and marula trees in a southern Mozambican savanna. Tree species did not affect herbaceous DM yield or species diversity. Neither direction nor distance from the tree trunk affected DM or specific diversity. Crude protein percentages were 15% higher for legumes and 9% higher for grasses at 50% canopy than at 200% canopy. Grasses under the marulas, the only non-legume tree in the study, had 18% …

Selecting New Brachiaria For Brazilian Pastures, Cacilda B. Do Valle, Valéria P. B. Euclides, Manuel C. M. Macedo, José R. Valério, S. Calixto

IGC Proceedings (1977-2023)

Brazilian beef production relies heavily on cultivated pastures, of which about 80% are planted mainly to two Brachiaria cultivars. The narrowness of diversity associated with reproduction by apomixis of most plants in this genus prompted an intense search for new cultivars amongst recently collected and introduced ecotypes from Africa. This paper reports results for a three-year evaluation of 21 pre-selected ecotypes in two typical Cerrado ecosystems. Plots, replicated four times, were seeded in rows and cut every 6 weeks during the rainy season followed by a cut in the middle and one at the end of the dry season. Significant …

Lesbian Single Parents: Reviewing Philippine Covid-19 Policies, Hazel T. Biana, Rosallia Domingo

Journal of International Women's Studies

The novel coronavirus pandemic magnifies existing inequalities experienced by single lesbian parents in the Philippines. While single parents already face huge challenges with having to combine work and care for children, dealing with inadequate income and social security, lack of childcare facilities, and debt, the unrecognized subgroup of lesbian single parents also have to deal with the detriments of a heterosexist and homophobic society. Reflecting on the countries’ existing Sexual Orientation or Gender Identity or Expression (SOGIE)-related single parent policies and possible inclusive strategies that may address such vulnerabilities, an analysis is done on the concerns faced by Filipino lesbian …

Diminishing Inequalities? A Study On Reconstituted Gender Relations In Bangladeshi Households During The Covid-19 Crisis, Soma Dey, Sanzida Akhter, Tasnim Nowshin Fariha

Journal of International Women's Studies

This article explores the gendered impact of the COVID-19 crisis in Bangladesh by analysing everyday practices within the household. Conceptually, we have followed R.W. Connell’s model of the structures of gender and Naila Kabeer’s perspective on women’s power to examine how a normative gender order involving heterosexual marital partners tends to be sustained during ‘normal’ times but can often be destabilised in the context of an unprecedented crisis. Based on an analysis of data collected through an online survey and in-depth interviews, our findings show that the COVID-19 crisis has generated an opportunity for challenging gender inequalities by diminishing the …

Feasibility Discussion Of Potential Carbon Offsetting Options For Nebraska, Andrew Mwape

School of Natural Resources: Faculty Publications

Conclusion

Highlighting the advantages and disadvantages of carbon offsetting options in the context of the state of Nebraska, this discussion shows that the choice and decisions about which option is better than the other depends on the interests at play and expected outcomes of the participation in carbon markets. However, irrespective of the motive to engage in emission reduction projects for carbon marketing, factors such as cost, and project efficiency can never be overlooked. Given the options discussed in this report, Nebraska has a lot of potential for carbon offsetting or emission reduction projects that would not only reduce and …

Relationship Of Cultivated Grain Amaranth Species And Wild Relative Accessions, Ranjita Thapa, Matthew Edwards, Matthew W. Blair

Agricultural and Environmental Sciences Faculty Research

Amaranthus is a genus of C4 dicotyledonous herbaceous plants, and three New World species have been domesticated to produce grain crops with light colored seed which are classified as pseudo-cereals rich in protein and minerals. A core collection of grain amaranths and immediate precursor species has been established, representing the closest related species. The goal of this study was to evaluate the genetic diversity in that collection of cultivated and wild species, using competitive allele single nucleotide polymorphism markers. A secondary objective was to determine the relationships among the three cultivated species and non-domesticated Amaranthus, while a third objective was …

Randomized And Non-Randomized Designs For Causal Inference With Longitudinal Data In Rare Disorders., Rima Izem, Robert Mccarter

Pediatrics Faculty Publications

In the United States, approximately 7000 rare diseases affect 30 million patients, and only 10% of these diseases have existing therapies. Sound study design and causal inference methods are essential to demonstrate the therapeutic efficacy, safety, and effectiveness of new therapies. In the rare diseases setting, several factors challenge the use of typical parallel control designs: the small patient population size, genotypic and phenotypic diversity, and the complexity and incomplete understanding of the disorder's progression. Repeated measures, when spaced appropriately relative to disease progression and exploited in design and analysis, can increase study power and reduce variability in treatment effect …

A Critical Discourse Analysis To Explain The Failure Of Bop Strategies, Nancy E. Landrum

School of Environmental Sustainability: Faculty Publications and Other Works

Purpose – This paper aims to highlight differences between business and non-business literature regarding base of the pyramid (BoP) and subsistence contexts and reveal discourse’s powerful role in influencing goals, solutions and outcomes.

Design/methodology/approach – This paper uses critical discourse analysis to review a convenience sample of business versus non-business literature on the BoP and subsistence contexts.

Findings – Discourse used in business literature on the BoP is oriented toward hegemonic Western capitalist approaches that result in the depletion of resources, resource inequalities, poverty and increased consumption, dependence and environmental degradation and, therefore, cannot alleviate poverty.

Research limitations/implications – There …

Microrna Analysis Of Human Stroke Brain Tissue Resected During Decompressive Craniectomy/Stroke-Ectomy Surgery, Andrew P. Carlson, William Mckay, Jeremy S. Edwards, Radha Swaminathan, Karen S. Santacruz, Ron L. Mims, Howard Yonas, Tamara Roitbak

Pathology Research and Scholarship

BACKGROUND: Signaling pathways mediated by microRNAs (miRNAs) have been identified as one of the mechanisms that regulate stroke progression and recovery. Recent investigations using stroke patient blood and cerebrospinal fluid (CSF) demonstrated disease-specific alterations in miRNA expression. In this study, for the first time, we investigated miRNA expression signatures in freshly removed human stroke brain tissue.

METHODS: Human brain samples were obtained during craniectomy and brain tissue resection in severe stroke patients with life-threatening brain swelling. The tissue samples were subjected to histopathological and immunofluorescence microscopy evaluation, next generation miRNA sequencing (NGS), and bioinformatic analysis.

RESULTS: miRNA NGS analysis detected …

Fever In A Returning Traveler: A Case And Literature Review Of Melioidosis, Akanksha Arya, Hamadullah Shaikh, Devin Weber, Matthew Pettengill, Sean Moss

Division of Infectious Diseases and Environmental Medicine Faculty Papers

Burkholderia pseudomallei is an aerobic, motile, non-spore-forming gram-negative bacillus found in tropical endemic environments that causes the disease melioidosis. Melioidosis displays a diversity of clinical presentations ranging from septic shock to chronic latent infection, often with characteristic abscesses in multiple organs. Melioidosis is an opportunistic infection, with risk factors, including diabetes, alcohol use, chronic lung disease, and chronic renal disease, and these risk factors increase the severity of disease (Wiersinga et al., 2006) [1]. In this case report, we illustrate a case of a 32 year old man with several risk factors and recent travel to an endemic region presenting …

“Safe Spaces” And “Brave Spaces”: The Case For Creating Law School Classrooms That Are Both, Laura P. Graham

University of Miami Law Review

Over the past decade, the subject of “safe spaces” on college and university campuses has received much press. As originally conceived, the term “safe space” refers to an environment—often a physical space—in which “everyone feels comfortable expressing themselves and participating fully, without fear of attack, ridicule, or denial of experience.” And while this original conception may not seem controversial, the meaning of “safe spaces” as applied to higher education classrooms is a subject of ongoing vigorous debate. On one side of the debate are those who believe that safe spaces foster learning by making it possible for students to be …

Basic Behavioral Processes Involved In Procrastination, Thomas R. Zentall

Psychology Faculty Publications

Procrastination involves an irrational putting off of engaging in a course of action, in spite of expecting to be worse off for the delay. I suggest that to understand the processes underlying procrastination one should examine its relation to several behavioral procedures that have been studied in humans and other animals. For example, in delay discounting, smaller rewards that come sooner are often preferred over larger rewards that come later. In the context of delay discounting, procrastination can be viewed as the preference for an immediate competing activity over the delay to work on a required task. Another process similar …

Competition And Geography Underlie Speciation And Morphological Evolution In Indo-Australasian Monitor Lizards, Carlos J. Pavón-Vázquez, Ian G. Brennan, Alexander Skeels, J. Scott Keogh

Publications and Research

How biotic and abiotic factors act together to shape biological diversity is a major question in evolutionary biology. The recent availability of large datasets and development of new methodological approaches provide new tools to evaluate the predicted effects of ecological interactions and geography on lineage diversification and phenotypic evolution. Here, we use a near complete phylogenomic-scale phylogeny and a comprehensive morphological dataset comprising more than a thousand specimens to assess the role of biotic and abiotic processes in the diversification of monitor lizards (Varanidae). This charismatic group of lizards shows striking variation in species richness among its clades and multiple …

Stone Monuments Of Northern Lake Eyasi Basin At Olpiro, Oldogom And Olbili Sites In The Ngorongoro Conservation Area, Tanzania: Revisited Perspectives, Musa S. Mwitondi, Pastory Bushozi, Albert S. Mjandwa

Journal of Humanities and Social Sciences

Despite the outstanding contribution of Lake Eyasi Basin to human origins and cultural development from the middle stone age (MSA) to the historic period, other archaeological occurrences in the area with outstanding cultural values such as burial cairns, stone enclosures, megalithic walls, and dolmens have remained less emphatic among scholars. Although these are widespread across the cultural landscape of the region, yet they have attracted little scientific attention. These stone monuments were first reported in the 1960s and 1970s, and precisely correlated to the agricultural terraces of Engaruka, the astonishing late iron age agricultural scheme of northern Tanzania. This study …

The Effects Of Household Shocks On Child Nutrition Status In Tanzania, Monica Sebastian Kauky, Martin Chegere, Razack Bakari Lokina

Journal of Humanities and Social Sciences

The main objective of this paper is to examine the effects of household shocks on the nutrition status of children between 0–59 months in Tanzania. The study employed the national panel survey data of Tanzania collected in three waves: 2008/09, 2010/11, and 2012/13. The study used the panel random-effects probit model to estimate the effects of household shocks on child nutrition status, measured by binary variables: stunting, wasting, and underweight. Findings indicated that weather shocks increase the probability of a child being stunted and underweight. Moreover, the results revealed that food price rise shocks and the death of a family …

Model Fitting And Analysis Of The Cost-Effectiveness Of Control Strategies In The Threatened Wildebeest-Lion Prey-Predator System In The Serengeti Ecosystem, Thadei D. Sagamiko

Journal of Humanities and Social Sciences

In this paper, a wildebeest-lion prey-predator model for the Serengeti ecosystem was adopted from a previous publication. The threats to the model system were poaching, retaliatory killings, and droughts. The proposed threat control strategies for these threats were anti-poaching patrol to mitigate poaching, construction of strong bomas to reduce retaliatory killings, and construction of dams to mitigate the impact of droughts. Data on the lion population density in the Serengeti ecosystem were used to fit the model by using the maximum likelihood method. The impact of different control strategies for a period of five years was analysed using the incremental …

Discussion Boards In The Online Classroom: Are They Actually Influencing Instructor Mediated Immediacy, Student Motivation, Student Affective Learning, Student Connectedness, And Online Learning Climate?, Samantha Lynn Schultz

Theses and Dissertations

Discussion boards are one of the most popular forms of asynchronous discussion in online classes. Utilized by instructors in asynchronous and synchronous courses to facilitate class discussions, they offer a means for the class to communicate among each other and with the instructor. Few researchers have examined how the use of discussion boards in the online classroom affects instructor mediated immediacy, student motivation, affective learning, connectedness, and the online learning climate. This study sought to examine the influence of discussion boards on these variables. After review of research on discussion boards and related variables, participants completed a questionnaire composed of …

Although there have been many studies of gene variant association with different stages of HIV/AIDS progression in United States and European cohorts, few gene-association studies have assessed genic determinants in sub-Saharan African populations, which have the highest density of HIV infections worldwide. We carried out genome-wide association studies on 766 study participants at risk for HIV-1 subtype C (HIV-1C) infection in Botswana. Three gene associations (AP3B1, PTPRA, and NEO1) were shown to have significant association with HIV-1C acquisition. Each gene association was replicated within Botswana or in the United States–African American or United States–European American AIDS …

Applying The Social Model Of Disability: A Phenomenology Of Initiating Change In Higher Education, Olena M. Marshall

College of Education Theses and Dissertations

In the past decades, disability service professionals in higher education began adopting the social model of disability as a theoretical and practical framework for creating more inclusive campus environments for students with disabilities who attend colleges and universities in growing numbers. Specifically, in the early 2000s, an international organization of disability service professionals, the Association on Higher Education and Disability, took on a strategic effort to shift the paradigm of disability services toward systematically removing barriers to full participation and transforming disabling environments—away from the prevalent modes of service focusing on the medical model, legal and regulatory compliance, and ad …

Interferometric Lithography- An Approach To Large Area And Cost Effective Nanopatterning, Vineeth Sasidharan

Optical Science and Engineering ETDs

In this dissertation interferometric lithography is approached in two different ways to address two important constraints of nanopatterning. One approach solves the problem of scaling up interferometric lithography to wafer scale (4 inch or larger) area. Through the second approach we have developed a nanopatterning technique based on interferometric lithography by using an inexpensive (~$100) diode laser as source, making interferometric lithography a very cost-effective technique.

Wafer-scale large-area nanopatterning was developed using an amplitude grating mask as a grating beam splitter along with spatial averaging of laser intensity by wobbling. The longitudinal and transverse coherence issues both are eased by …
