Determinants Of Farm And Non-Farm Family-Controlled Child Labor, Kofi Acheampong

International Journal of African Development

Ninety five percent of the child labor in Africa takes place in private households where children are controlled by their relatives. While this is a major problem, the literature provides little discussion on the determinants of this form of child labor. To fill this gap, I examine the determinants of farm and non-farm family-controlled child labor using data from the 2009 Ghana Time Use Survey. The findings indicate that school networks, the education level of the head of household, and religion play important roles in determining children’s activities in both farm and non-farm work.

Evaluation Of A New Automated Pulmonary Gas Analysis System, Tove Hallenstål, Ida Sundqvist, Michael Svensson, Ji-Guo Yu Dr.

International Journal of Exercise Science

International Journal of Exercise Science 8(3): 287-296, 2015. The study aimed to evaluate the validity and reliability of a new automated pulmonary gas analysis system - Exercise Physiology System (EPS). The Oxycon Pro, a well-established automated pulmonary gas analysis system was used as a reference system. Six well-trained cyclists were recruited and performed two identical submaximal exercises on a cycle ergometer over one week interval. During the exercises, pulmonary gas exchange: ventilation (VE), oxygen consumption (VO₂), elimination of carbon dioxide (VCO₂), and ratio between carbon dioxide and oxygen (RER) was measured using both systems in randomized …

Effect Of Beetroot Juice On Self-Regulated, Moderate-Intensity Exercise, Jordyn N. Rienks, Andrea A. Vanderwoude, Elizabeth Maas, Zachary M. Blea, Andrew W. Subudhi

International Journal of Exercise Science

International Journal of Exercise Science 8(3): 277-286, 2015. Dietary nitrate supplementation has been shown to reduce oxygen consumption at a fixed work rate. We questioned whether a similar effect would be observed during variable work rate exercise at a specific rating of perceived exertion (RPE), as is commonly prescribed for aerobic training sessions. Using a double-blind, placebo controlled, crossover design, ten females (25 ± 3 years; VO₂peak 37.1 ± 5.3 ml/kg/min) performed two 20-min cycle ergometer trials at a constant RPE of 13 (somewhat hard) 2.5 hours following ingestion of 140 ml of concentrated beetroot juice (12.9 mmol …

Parts Of The Whole: Quantitative Literacy On A Desert Island, Dorothy Wallace

Numeracy

Some of the specific institutional problems faced by quantitative reasoning courses, programs and requirements arise from the fragile intellectual position of “quantitative reasoning” as an idea, or meme. The process of isolation and reintroduction explains both the proliferation of living species and the way in which some difficult ideas take their place in a culture. Using evolutionary explanations as metaphor and the Copernican revolution as an example of a difficult idea, we draw lessons that can be applied to the “quantitative reasoning” meme, including the function of the National Numeracy Network as an island of protected discourse favoring the growth …

Adapting To A New Core Curriculum At Hood College: From Computation To Quantitative Literacy, Betty Mayfield, Jill B. Dunham

Numeracy

Our institution, a small, private liberal arts college, recently revised its core curriculum. In the Department of Mathematics, we took this opportunity to formally introduce Quantitative Literacy into the language and the reality of the academic requirements for all students. We developed a list of characteristics that we thought all QL courses should exhibit, no matter in which department they are taught. We agreed on a short list of learning outcomes for students who complete those courses. Then we conducted a preliminary assessment of those two attributes: the fidelity of QL-labeled courses to our list of desired characteristics, and our …

Numeracy Infusion Course For Higher Education (Niche), 1: Teaching Faculty How To Improve Students' Quantitative Reasoning Skills Through Cognitive Illusions, Frank Wang, Esther I. Wilder

Numeracy

We describe one of the eight units of a professional development program, the Numeracy Infusion Course for Higher Education (NICHE), which introduces research on cognition, including dual-processing theories, to university faculty. Under the dual-processing framework, System 1 (intuition) quickly proposes intuitive answers to judgment problems as they arise, while System 2 (deliberation) monitors the quality of these proposals, which it may endorse, correct, or override. We present several classic questions that demonstrate the pitfalls of overreliance on intuition without analytical thinking, then describe faculty participants’ responses to these questions and their ideas on how to apply cognitive illusion research to …

The Math You Need, When You Need It (Tmyn): Leveling The Playing Field, Jennifer M. Wenner, Eric M. D. Baer

Numeracy

The Math You Need, When You Need It (TMYN) is a set of online tutorials designed to help students develop and review mathematical skills that are applied in undergraduate geoscience courses. We present results of a three-year study of more than 4000 students in 106 geoscience courses at a variety of post-secondary schools who were assigned TMYN tutorials as supplemental mathematics instruction. Changes in student scores from pre- to post-test suggest that the support provided by programs such as TMYN can begin to reduce the gap between mathematically well-prepared and underprepared students; in essence, TMYN levels the quantitative playing field …

The Quantitative Reasoning For College Science (Quarcs) Assessment, 1: Development And Validation, Katherine B. Follette, Donald W. Mccarthy, Erin Dokter, Sanlyn Buxner, Edward Prather

Numeracy

Science is an inherently quantitative endeavor, and general education science courses are taken by a majority of college students. As such, they are a powerful venue for advancing students’ skills and attitudes toward mathematics. This article reports on the development and validation of the Quantitative Reasoning for College Science (QuaRCS) Assessment, a numeracy assessment instrument designed for college-level general education science students. It has been administered to more than four thousand students over eight semesters of refinement. We show that the QuaRCS is able to distinguish varying levels of quantitative literacy and present performance statistics for both individual items and …

Comparisons Between Survival Models In Predicting Cardiovascular Disease Events: Application In The Attica Study (2002-2012)., Ekavi N Geogrousopoulou, Christos Pitsavos, Mary Yannakoulia, Demosthenes B Panagiotakos

Journal of Statistics Applications & Probability

In order to assess individual’s risk of a disease, semi-parametric proportional hazards Cox models are mostly used, while fewer studies have used parametric models. The aim of the present work was to compare semi-parametric and parametric statistical methods regarding their goodness of fit. To investigate the research hypothesis, characteristics of the 3042 participants of the ATTICA epidemiological study, were used; 2583 of them were found in the 10-year follow-up (2011-2012) and 317 (15.7%) developed a cardiovascular disease event. Three multivariable models, adjusted for the same set of risk factors were compared regarding their performance, using the Bayesian Information Criterion (BIC). …

Some Discussion On Behaviors Of Markov Q-Process, Azam Abdurakhimovich Imomov

Journal of Statistics Applications & Probability

Consider the limiting probability function of continuous-time Markov Branching Processes conditioned to be never extinct. Hereupon we receive a new stochastic population process as a continuous-time Markov chain called the Markov Q-Process. We study main properties of Markov Q-Process. The principal aim is to investigate asymptotic properties of Markov Q-Process. We investigate transition functions of this process and their convergence to stationary measures.

Transdisciplinarity: A Review Of Its Origins, Development, And Current Issues, Jay H. Bernstein

Publications and Research

Transdisciplinarity originated in a critique of the standard configuration of knowledge in disciplines in the curriculum, including moral and ethical concerns. Pronouncements about it were first voiced between the climax of government-supported science and higher education and the long retrenchment that began in the 1970s. Early work focused on questions of epistemology and the planning of future universities and educational programs. After a lull, transdisciplinarity re-emerged in the 1990s as an urgent issue relating to the solution of new, highly complex, global concerns, beginning with climate change and sustainability and extending into many areas concerning science, technology, social problems and …

Osmotic Stress Induces Phosphorylation Of Histone H3 At Threonine 3 In Pericentromeric Regions Of Arabidopsis Thaliana, Zhen Wang, Juan Armando Casas-Mollano, Jianping Xu, Jean-Jack M. Riethoven, Chi Zhang, Heriberto Cerutti

Center for Plant Science Innovation: Faculty Publications

Histone phosphorylation plays key roles in stress-induced transcriptional reprogramming in metazoans but its function(s) in land plants has remained relatively unexplored. Here we report that an Arabidopsis mutant defective in At3g03940 and At5g18190, encoding closely related Ser/Thr protein kinases, shows pleiotropic phenotypes including dwarfism and hypersensitivity to osmotic/salt stress. The double mutant has reduced global levels of phosphorylated histone H3 threonine 3 (H3T3ph), which are not enhanced, unlike the response in the wild type, by drought-like treatments. Genome-wide analyses revealed increased H3T3ph, slight enhancement in trimethylated histone H3 lysine 4 (H3K4me3), and a modest decrease in histone H3 occupancy …

Mechanical Properties Of A Primary Cilium As Measured By Resonant Oscillation, Andrew Resnick

Physics Faculty Publications

Primary cilia are ubiquitous mammalian cellular substructures implicated in an ever-increasing number of regulatory pathways. The well-established ciliary hypothesis states that physical bending of the cilium (for example, due to fluid flow) initiates signaling cascades, yet the mechanical properties of the cilium remain incompletely measured, resulting in confusion regarding the biological significance of flow-induced ciliary mechanotransduction. In this work we measure the mechanical properties of a primary cilium by using an optical trap to induce resonant oscillation of the structure. Our data indicate 1) the primary cilium is not a simple cantilevered beam; 2) the base of the cilium may …

Structural And Functional Connectivity As A Driver Of Hillslope Erosion Following Disturbance, Christopher Jason Williams, Frederick B. Pierson, Peter R. Robichaud, Osama Z. Al-Hamdan, Jan Boll, Eva K. Strand

Articles

Hydrologic response to rainfall on fragmented or burnt hillslopes is strongly influenced by the ensuing connectivity of runoff and erosion processes. Yet cross-scale process connectivity is seldom evaluated in field studies owing to scale limitations in experimental design. This study quantified surface susceptibility and hydrologic response across point to hillslope scales at two degraded unburnt and burnt woodland sites using rainfall simulation and hydrologic modelling. High runoff (31–47 mm) and erosion (154–1893 g m^–2) measured at the patch scale (13 m²) were associated with accumulation of fine-scale (0.5-m²) splash-sheet runoff and sediment and concentrated …

Altered Lysosomal Proteins In Neural-Derived Plasma Exosomes In Preclinical Alzheimer Disease, Edward J. Goetzl, Adam Boxer, Janice B. Schwartz, Erin L. Abner, Ronald C. Petersen, Bruce L. Miller, Dimitrios Kapogiannis

Sanders-Brown Center on Aging Faculty Publications

OBJECTIVE: Diverse autolysosomal proteins were quantified in neurally derived blood exosomes from patients with Alzheimer disease (AD) and controls to investigate disordered neuronal autophagy.

METHODS: Blood exosomes obtained once from patients with AD (n = 26) or frontotemporal dementia (n = 16), other patients with AD (n = 20) both when cognitively normal and 1 to 10 years later when diagnosed, and case controls were enriched for neural sources by anti-human L1CAM antibody immunoabsorption. Extracted exosomal proteins were quantified by ELISAs and normalized with the CD81 exosomal marker.

RESULTS: Mean exosomal levels of cathepsin D, lysosome-associated membrane …

Food Sharing Among Hadza Hunter-Gatherer Children, Alyssa N. Crittenden, David A. Zes

Anthropology Faculty Research

Human prosociality is one of the defining characteristics of our species, yet the ontogeny of altruistic behavior remains poorly understood. The evolution of widespread food sharing in humans helped shape cooperation, family formation, life history, language, and the development of economies of scale. While the behavioral and ecological correlates of food sharing among adults are widely studied, very little is known about food sharing among children. Here, in the first study to analyze the food sharing patterns of hunter-gatherer children, we show that while sharing may be biased towards kin, reciprocity characterizes the majority of all sharing dyads, both related …

Astrocytic Expansion In A Model Of Neurofibromatosis 1 (Nf1) Deficiency, Joel Rosiene

Master's Theses

Neurofibramatosis type 1 is an autosomal dominant disorder characterized by the development of both benign and malignant neoplasms of glial origin, as well as learning deficits and, less frequently, macrocephaly. Essential to the understanding of NF1 is the observation that the peripheral neoplasms (neurofibroma) which develop are composed primarily of NF1 negative glia which have undergone a loss of NF1 heterozygosity. The etiology of this loss of heterozygosity remains unclear, but a better characterization of these mutation events would provide insight into the cellular origins of the NF1 phenotype. CRISPR/Cas9 systems for genome editing have been, since 2013, a significant …

Tissue Characterization Using Optical Coherence Tomography, Mina Mahdian

Master's Theses

Optical coherence tomography (OCT) is a non-invasive imaging modality, which provides real-time near-histology resolution images. In dentistry, OCT has been used for early detection of carious lesions, malignant changes in the oral tissues and other indications. However, to the best of our knowledge there is no information regarding the ability of this imaging modality in differentiating between different types of tissues in the oral cavity. If OCT proves to be able to render information regarding the properties of tissues, it can be used to detect pathological changes at an early stage, which results in better treatment outcomes. In this study, …

A small proportion of 4H (Hypomyelination, Hypodontia and Hypogonadotropic Hypogonadism) or RNA polymerase III (POLR3)-related leukodystrophy cases are negative for mutations in the previously identified causative genes POLR3A and POLR3B. Here we report eight of these cases carrying recessive mutations in POLR1C, a gene encoding a shared POLR1 and POLR3 subunit, also mutated in some Treacher Collins syndrome (TCS) cases. Using shotgun proteomics and ChIP sequencing, we demonstrate that leukodystrophy-causative mutations, but not TCS mutations, in POLR1C impair assembly and nuclear import of POLR3, but not POLR1, leading to decreased binding to POLR3 target genes. This study is the first …

Alterations In Activation, Cytotoxic Capacity And Trafficking Profile Of Peripheral Cd8 T Cells In Young Adult Binge Drinkers, José Luis Zaldivar Fujigaki, América Guadalupe Arroyo Valerio, Juan Carlos Lopez Alvarenga, Esperanza Gabriela Gutiérrez Reyes, David Kershenobich, Joselin Hernández Ruiz

School of Medicine Publications

Background: Excess of alcohol consumption is a public health problem and has documented effects on the immune system of humans and animals. Animal and in vitro studies suggest that alcohol abuse changes CD8 T cell (CD8) characteristics, however it remains unknown if the CD8 profile of binge drinkers is different in terms of activation, trafficking and cytotoxic capacity.

Aim: To analyze the peripheral CD8 cytotoxic capacity, activation and trafficking phenotypic profile of Mexican young adults with regard to alcohol consumption pattern.

Methods: 55 Mexican young adults were stratified as Light (20), Intermediate (18) or Binge drinkers (17) according to their …
