Instructional Decision Making In A Gateway Quantitative Reasoning Course, Deependra Budhathoki, Gregory D. Foley, Stephen Shadik

Numeracy

Many educators and professional organizations recommend Quantitative Reasoning as the best entry-level postsecondary mathematics course for non-STEM majors. However, novice and veteran instructors who have no prior experience in teaching a QR course often express their ignorance of the content to choose for this course, the instruction to offer students, and the assessments to measure student learning. We conducted a case study to investigate the initial implementation of an entry-level university quantitative reasoning course during fall semester, 2018. The participants were the course instructor and students. We examined the instructor’s motives and actions and the students’ responses to the course. …

Methods For Achieving A Target Joint Preload, Daniel P. Hess

USF Patents

A method for achieving a target joint preload includes identifying a thread pitch of a first fastener element used to secure two components together. The first fastener element is passed through the two components and a second fastener element is threaded onto the first fastener element. A tightening torque is applied to the second fastener element, which is measured as the trial tightening torque. A loosening torque is applied to the second fastener element, which is measured as the trial removal torque. A required tightening torque that is required to be applied to the second fastener element to achieve the …

Assessing Compliance To Water Resources And Reconstruction Framework During Post-Conflict Reconstruction Borno State, Muritala Olaniyi Oke Dr

Journal of African Conflicts and Peace Studies

Northeast and northwest of Nigeria have, as a result of activities of Boko Haram, bandit and kidnappers, had their public and private properties destroyed. Governments and other stakeholders, upon some successes of the military, have started post-conflict reconstruction to rebuild the war-torn urban and rural communities with the provision of water taking the center stage. This paper looks at the utilisation of Water Resources and a Reconstruction framework for integrating water projects into reconstruction processes. This paper rests on the argument that water projects during reconstruction should not be handled as “normal” water projects and that a more culturally and …

Dynamic Prediction Of Shared Micromobility Usage With Multi-Task Learning, Yujie Guo, Ying Chen, Yu Zhang

Research Reports

Taxis and Transportation Network Companies (TNCs) are important components of the urban transportation system. An accurate short-term forecast of passenger demand can help operators better allocate taxi or TNC services to achieve supply–demand balance in real time. As a result, drivers can improve the efficiency of passenger pick-ups, thereby reducing traffic congestion and contributing to the overall sustainability of the program. Previous research has proposed sophisticated machine learning and neural-network-based models to predict the short-term demand for taxi or TNC services. However, few of them jointly consider both modes, even though the short-term demand for taxis and TNCs is closely …

A Study On The Correlation Between A Star's Rayleigh-Taylor Characteristic Timescale And Stellar Wind Activity, Fiona Klett

Undergraduate Journal of Mathematical Modeling: One + Two

In this paper, we investigate the correlations between a star's internal dynamics due to the Rayleigh-Taylor instability and episodes of stellar wind activity, using both a theoretical model and observational data from the NOAA.% \cite{NOAA}. Besides its relevance as an astrophysics problem, this study is also informative for models of climate change which include secular perturbations in the Sun's internal dynamics, as a potential source of solar activity variability.

Quantifying Non-Primary Dna Formations Through Mechanical And Geometric Models, Sonia E. Teodorescu

Undergraduate Journal of Mathematical Modeling: One + Two

In this article, mechanical and geometric models for DNA strains (regarded as a helical structure in 3 dimensions, embedded into surfaces of various shapes (straight or curved cylinders, spheres, or projected into planes), are analyzed in order to obtain parameter estimates for DNA characteristics which can be used to detect the formation of secondary and tertiary formations in the presence of disorder. The models allow for the explicit representation of the DNA shape on constrained geometries and can therefore be implemented directly into {\it{ab initio}} or synthetic simulation studies.

Evaluation Of Information Visualization In Digital Intelligence Product, Dejan Ulcej, Anja Podlesek

Journal of Strategic Security

Digital technology has impacted how strategic intelligence products are designed and distributed to political security decisionmakers. Information visualization helps improve the processing of intelligence information. This experimental study investigated whether a prototype digital intelligence report that uses visuals is processed more efficiently and results in a better user experience than a printed intelligence product that contains primarily text. A sample of 72 participants working as decisionmakers in a private company was divided into two equal groups. One group received the digital version of the report, and the other received the printed version. The time it took to read the report, …

Threshold Concepts In Quantitative Reasoning, Judith Canner, Jennifer E. Clinkenbeard

Numeracy

The idea of “threshold concepts” has been used to identify discipline-based concepts that are critical to that academic area. Threshold concepts are often difficult for students to assimilate in a meaningful way but, once done, can be powerful for the learner. In general, threshold concepts are 1) transformative to learner thinking; 2) bounded by the discipline; 3) integrative with other concepts; and 4) irreversible once understood (Meyer and Land 2003). This paper presents five threshold concepts in quantitative reasoning (QR) developed by transdisciplinary faculty workgroups that may be applicable for non-mathematics disciplines as well. They are as follows: 1) QR …

Tuberculosis Treatment Loss To Follow-Up In Children Exposed At Home: A Prospective Cohort Study, Meredith B. Brooks, Brittney J. Van De Water, Leonid Lecca, Chuan-Chin Huang, Letizia Trevisi, Carmen Contreras, Jerome T. Galea, Roger Calderon, Rosa Yataco, Megan Murray, Mercedes C. Becerra

Social Work Faculty Publications

Background: Loss to follow-up (LTFU) from tuberculosis (TB) treatment and care is a significant public health problem. It is important to understand what drives LTFU in children – a population whose treatment and management depend on an adult caregiver – to better provide support services to families affected by TB.

Methods: We conducted a prospective cohort study of household contacts in Lima, Peru (2009–12). Using multilevel logistic regression analysis, we explored individual-level characteristics of children and their adult household members with TB disease to identify risk factors for LTFU among children initiated on treatment for TB.

Results: A total of …

Agriculture Against The Wall: Barriers And Opportunities For Agroecological Transitions In California’S Industrial Agricultural Landscapes, Estelí Jiménez-Soto, Madeleine Fairbairn, Joji Muramoto, Carol Shennan

School of Geosciences Faculty and Staff Publications

Agroecology emphasizes a shift from low diversity, high chemical input farming to more biodiverse agroecosystems cultivated in conjunction with natural ecosystem processes and embedded in socially just relationships. Yet achieving such agroecological transitions presents enormous challenges in industrial agricultural landscapes dominated by consolidation and overproduction. We examine both the challenges and the opportunities for agroecological transition in one particular industrial agricultural context: the fumigant-dependent strawberry production of California’s Central Coast. We do so by exploring adoption of Anaerobic Soil Disinfestation (ASD), an agroecological alternative to fumigation which has shown considerable promise but has been historically underutilized. Building on previously identified …

Marine Science Faculty Publications

The presented pilot for the Synthesis Product for Ocean Time Series (SPOTS) includes data from 12 fixed ship-based time-series programs. The related stations represent unique open-ocean and coastal marine environments within the Atlantic Ocean, Pacific Ocean, Mediterranean Sea, Nordic Seas, and Caribbean Sea. The focus of the pilot has been placed on biogeochemical essential ocean variables: dissolved oxygen, dissolved inorganic nutrients, inorganic carbon (pH, total alkalinity, dissolved inorganic carbon, and partial pressure of CO2), particulate matter, and dissolved organic carbon. The time series used include a variety of temporal resolutions (monthly, seasonal, or irregular), time ranges (10–36 years), and bottom …

Evidence That Ericoid Mycorrhizal Shrubs Can Outcompete Ectomycorrhizal Trees For Nitrogen In Tannin-Rich Litter, Kai C. Rains, Caroline Bledsoe, Tamara E. Kraus, Nina Wurzburger

School of Geosciences Faculty and Staff Publications

Mycorrhizal associations of trees play a key role in ecosystem biogeochemistry, yet we know relatively little about the nutrient acquisition strategies of ericoid mycorrhizal (ErM) shrubs, despite their prevalence in forest understories. ErM shrubs tend to produce litter with high concentrations of polyphenols, which form decay-resistant complexes with organic nitrogen (N). Some ErM fungi appear capable of producing a diverse suite of extracellular enzymes, but it is unclear whether this enables ErM shrubs to acquire the N from their own litter, and whether this ability is greater than that of ectomycorrhizal (EcM) trees, with which they commonly co-occur. Here, we …

Uav-Based Wetland Monitoring: Multispectral And Lidar Fusion With Random Forest Classification, Robert Van Alphen, Kai C. Rains, Mel Rodgers, Rocco Malservisi, Timothy H. Dixon

School of Geosciences Faculty and Staff Publications

As sea levels rise and temperatures increase, vegetation communities in tropical and sub-tropical coastal areas will be stressed; some will migrate northward and inland. The transition from coastal marshes and scrub–shrubs to woody mangroves is a fundamental change to coastal community structure and species composition. However, this transition will likely be episodic, complicating monitoring efforts, as mangrove advances are countered by dieback from increasingly impactful storms. Coastal habitat monitoring has traditionally been conducted through satellite and ground-based surveys. Here we investigate the use of UAV-LiDAR (unoccupied aerial vehicle–light detection and ranging) and multispectral photogrammetry to study a Florida coastal wetland. …

Climate Monitoring In The Caumont Cave And Quarry System (Northern France) Reveal Near Oxygen Isotopic Equilibrium Conditions For Carbonate Deposition, Ingrid Bejarano-Arias, Carole Nehme, Sebastian Breitenbach, Hanno Meyer, Sevasti Modestou, Damase Mouralis

International Journal of Speleology

The study of modern cave deposits forming under near isotopic equilibrium conditions can potentially help disentangle the processes influencing the oxygen isotope system and suitability of stalagmites as archives of past hydrological or thermal changes. We used cave monitoring to evaluate the impact of kinetic isotope fractionation and assess the conditions under which modern cave carbonates form in the Caumont cave and quarry system, located in Normandy, northwest France. Over 20 months, we collected climatological data, dripwater, and modern carbonate samples at 2–4-week intervals at three different stations inside the Caumont cave and quarry system. We find highly stable (10.4 …

Effect Of Influencers On The Intention To Taste Local Food And Beverages, Yeliz Demir, Serkan Bertan

Journal of Mediterranean Tourism Research

The study aims to determine the impact of influencers promoting local food and beverages on individuals’ intention to taste local food. In this study, Instagram accounts were selected as the social media platform. The research data were obtained from Turkish Instagram users over the age of 18 by using an online survey and purposive sampling method, and usable data were obtained from 81 people. Of the participants, 56.8% stated that they follow Instagram accounts related to gastronomy, and 43.2% stated that they do not follow these social media accounts but look at the photos and videos of gastronomy accounts when …

Reverse Pseudo-Gours: A New Sub-Type Of Folia Observed In The Nerja Cave (Se Spain), Cristina Liñán Baena, Concepción Jiménez De Cisneros, Yolanda Del Rosal, Paolo Forti

International Journal of Speleology

A new sub-type of folia named “reverse pseudo-gour” has been observed and described in the Nerja Cave, southern Spain. It consists of fairly vertical, thin barriers (about 5 mm high and 2 mm thick) that develop on the underside of a sub-horizontal surface (shelfstone) and grow in the opposite direction to normal gours (rimstone dams), generating sinuous shapes. Their mineral composition is essentially calcium carbonate, although globular aggregates composed of clay and phosphate minerals have also been identified. The genesis and evolution of these reverse pseudo-gours occur just at the air-water interface and are controlled by (1) the sub-horizontality of …
