Perceived Vs. Actual Distance To Transit In Santiago, Chile, Diego Hernández, Regina Witter

Journal of Public Transportation

To plan public transport supply and to increase transit patronage, it is indispensable to be aware of people’s perception of the actual supply, that is, how extensive and accurate people’s knowledge is regarding the concrete features of transport supply, such as the locations of transit stops, timetables, and fare structures. This paper addresses the gap between the perceived and real distances to transit stops. The comparison between the real and perceived supply shows a considerably accurate perception. Nevertheless, a pattern is apparent. Metro supply has a higher overestimation rate than buses, i.e., walking distances are perceived as significantly shorter than …

Analyzing And Assessing The Experience Of Traveling By Public Transport, Martin Schiefelbusch

Journal of Public Transportation

The experience of traveling (as an aggregate of sensory impressions in relation to social and psychological needs) has so far rarely been considered as a factor influencing travel and modal choice. This paper proposes a practical way to disaggregate the “travel experience” into its separate components and suggests a procedure to assess the “experiential qualities” of (mainly public) transport services. This assessment allows planners to compare different user groups’ expectations as well as the provider’s strategic objectives. The procedure then is discussed in relation to several recent strands of transport/mobility research that are approaching the travel experience from different points …

Perceptions Of Crime Prevention Through Environmental Design (Cpted) At Australian Railway Stations, Paul Cozens, Tiffany Van Der Linde

Journal of Public Transportation

Personal safety and security are essential criteria for measuring the quality of public transport, and research has consistently demonstrated that crime and fear of crime affect levels of patronage. Although authorities throughout the world are implementing Crime Prevention Through Environmental Design (CPTED), research and practice commonly focus on the elements of surveillance, territoriality, and controlling access. Few studies have investigated the CPTED concepts of “image management” or “geographical juxtaposition” (the surrounding environment). This research compares and contrasts the perceptions of rail users and security experts in relation to two railway stations in Perth, Western Australia. One station was designed in …

Fire And Flood Expand The Floodplain Shifting Habitat Mosaic Concept, W. J. Kleindl, Mark C. Rains, L. A. Marshall, F. R. Hauer

School of Geosciences Faculty and Staff Publications

The floodplain shifting habitat mosaic concept suggests that habitat patch dynamics are influenced by hydrologic disturbances driven by flood pulses of sufficient power to initiate incipient motion of the substratum and maintain cut-and-fill alluviation of the channel and banks. However, floodplain habitat mosaics are subject to other important landscape-scale disturbance regimes. In the Rocky Mountains of the USA and Canada, fire also affects floodplain habitat patch composition. The floodplain exists at the intersection of disturbance regimes that shape the riverscape and those that shape the landscape. We extended the shifting habitat mosaic concept by examining the effects of multiple disturbance …

Nuovi Dati Sulla Produzione Ceramica Tipo Thapsos Di Area Etnea: Il Caso Di Grotte Di Marineo (Licodia Eubea, Catania), Davide Tanasi

History Faculty Publications

The general lack of data about the technological features of the production represents the main problem of the archaeological research on Sicilian prehistoric. In particular, about the Middle Bronze Age, a period corresponding to the Thapsos culture and its three chronological phases (15th-13th century BC), the only studies available are those about Aeolian islands and still nothing exists for Sicily. The present paper aims to bridge this gap discussing the ceramic materials found at Grotte di Marineo, a prehistoric cave site explored in 1988-1989. Middle Bronze Age contexts at Grotte di Marineo were represented by the test pit 2 (layers …

Bit By Bit: Using Design-Based Research To Improve The Health Literacy Of Adolescents, Mega Subramaniam, Beth St. Jean, Natalie Greene Taylor, Christie Kodama, Rebecca Follman, Dana Casciotti

School of Information Faculty Publications

Background: Although a low health literacy level has been found to be among the most powerful predictors of poor health outcomes, there is very little research focused on assessing and improving the health literacy skills of adolescents, particularly those from socioeconomically disadvantaged backgrounds. The vast majority of existing research focuses solely on reading comprehension, despite the fact that health literacy is actually a multifaceted concept, which entails many different types of skills.

Objective: The aim of this paper is to first mine existing literature to identify the many different skills that have been posited to constitute health literacy, and then, …

Genetic Analyses Determine Connectivity Among Cave And Surface Populations Of The Jamaican Endemic Freshwater Crab Sesarma Fossarum In The Cockpit Country, Manuel Stemmer, Christoph D. Schubart

International Journal of Speleology

The Jamaican freshwater crab Sesarma fossarum (Decapoda: Brachyura: Sesarmidae) is endemic to western central Jamaica where it occurs in cave and surface streams of karst regions. In the present study, we examine the population genetic structure of the species, providing evidence for intraspecific differentiation and genetic substructure among twelve sampled populations. Interestingly, crabs from caves appear genetically undistinguishable from representatives of nearby surface waters, despite previously observed and described morphometric differentiation. In contrast, genetic isolation takes place among populations from rivers and caves belonging to different watersheds. In one case, even populations from different tributaries of the same river were …

Lighting Conditions And Optical Filters Effects On Visual Performance Of Speleologists Exposed To Cave Environments, Carla Costa Lança, Nádia Fernandes, Ana Monteiro, Ana Almeida

International Journal of Speleology

The aim of this study is to evaluate lighting conditions and speleologists’ visual performance using optical filters when exposed to the lighting conditions of cave environments. A cross-sectional study was conducted. Twenty-three speleologists were submitted to an evaluation of visual function in a clinical lab. An examination of visual acuity, contrast sensitivity, stereoacuity and flashlight illuminance levels was also performed in 16 of the 23 speleologists at two caves deprived of natural lightning. Two organic filters (450nm and 550nm) were used to compare visual function with and without filters. The mean age of the speleologists was 40.65 (± 10.93) years. …

Resource Recovery Through Halophyte Production In Marine Aquaponics: An Evaluation Of The Nutrient Cycling And The Environmental Sustainability Of Aquaponics, Suzanne Boxman

USF Tampa Graduate Theses and Dissertations

Aquaculture, the farming of aquatic animals and plants, is an important component of global food production, which supplies a nutritious protein source for millions of people. Interest in improving the sustainability of aquaculture has led to the development of aquaponics in which fish production is combined with plant production to create zero-discharge systems. A need for more fundamental science and engineering research on marine aquaculture and growing interest in production of halophytes motivated this novel research on marine aquaponics. One objective was to evaluate the growth and nutrient removal capacity of halophytes in marine aquaponics. Bench-scale studies were conducted to …

Synthesis Of Agents For The Treatment And Analysis Of Tropical Diseases, Jeanine Yacoub

USF Tampa Graduate Theses and Dissertations

Toxoplasmosis is an opportunistic disease caused by the protozoan parasite Toxoplasma gondii. The parasite is usually staved off by a healthy immune system and remains dormant in the body. In immunocompromised patients, the parasite can become active and spread throughout the body causing symptoms such as encephalitis, cognitive disorders, seizures, and death. Combination drug therapy is the usual treatment for toxoplasmosis; however, patients suffer from problems of intolerance, allergic reactions, and cytotoxicity. In an effort to identify new drug targets for toxoplasmosis, a series of compounds have been synthesized that can be used as tools to probe the unique …

Developing Differentiated Reading Instruction Online For Gifted Third Graders: A Design Experiment, Beth E. Jordan

USF Tampa Graduate Theses and Dissertations

The high stakes on standardized testing in the United States of America’s education system pressures teachers to ensure every child meets minimum standards. Teachers report this pressure motivates them to focus the majority of their time on struggling students. Combined with lack of training and resources, intellectually gifted students may remain under-challenged in a regular elementary classroom. To address the problem, the researcher continued the development of an online instructional environment, which teachers may use to extend and enrich the regular language arts curriculum for intellectually gifted students. The researcher conducted a formative design experiment “to create a viable theory-driven …

Living Among The Ruins Of An Unknown Past: Economic Realities, Sociocultural Perceptions, And Archaeological Practice In The Naco Valley, Honduras, Jose Enrique Moreno-Cortes

USF Tampa Graduate Theses and Dissertations

This study addresses the relationship between perceptions of cultural patrimony, socioeconomic realities, and interactions with archaeological sites in two rural communities in the Naco Valley, Honduras. Palmarejo and Palos Blancos are communities situated around the Naco Valley, that share their space with two major archaeological sites.The residents of these communities interact with the archaeological sites by using their area for farming, cattle grazing, and social/recreational activities. On several occasions, the mounds in the archaeological sites have been used as a source of raw materials for construction. Thus far, the damage to the ruins by these activities has been minimal. However, …

Ammonium Removal From High Strength Wastewater Using A Hybrid Ion Exchange Biological Process, Veronica Ester Aponte-Morales

USF Tampa Graduate Theses and Dissertations

Anaerobic digestion (AD) has been shown to be an effective technique for energy recovery and stabilization of livestock wastes, municipal sludges and industrial wastewaters. However, further treatment is required to remove nitrogen from AD effluents to avoid detriments to surface and ground waters. The high free ammonia (FA) concentrations present in AD effluents can inhibit nitrification processes in conventional biological nitrogen removal (BNR) systems. The overall goal of this research was to develop a process for removal of nitrogen from AD swine waste (ADSW) effluent. The proposed solution was to incorporate particulate chabazite, which has a high cation exchange capacity, …

Optofluidic Spectroscopy Platform For Detection Of Hemolysis, Edikan Archibong

USF Tampa Graduate Theses and Dissertations

In the United States alone, hundreds of millions of blood tests are performed annually, and a significant number of those tests are compromised due to hemolysis: e.g., 31% compromised in emergency rooms (inpatient) and 10% at blood banks, clinics, and other outpatient venues. Currently there is no way to reliably detect hemolysis without plasma separation. As a result, significant delays ensue, potentially negatively affecting patient diagnosis and treatment. In addition to in vitro hemolysis, which compromises the quality of blood tests, hemolysis can also occur in vivo. The in vivo occurrence of hemolysis is an indication of life-threatening complications. …

Multiple Scales Of Beach Morphodynamic Processes: Measurements And Modelling, Jun Cheng

USF Tampa Graduate Theses and Dissertations

Multiple scales of beach morphodynamic processes ranging from those of wave-breaking induced turbulence, individual wave, storm, seasonal, to inter-annual are examined in this dissertation based on both laboratory and field data. These processes were simulated using process-based numerical models and data-driven models.

At a microscale, separating turbulence from orbital motion under breaking waves in the surf zone is essential to understanding wave-energy dissipation. Velocity data under monochromatic and random waves in the large-scale sediment transport facility (LSTF) were analyzed. Moving averaging provides a simple method for extracting turbulence from velocity measurements under random breaking waves collected at a reasonably high …

The Relationship Of Childhood Stress To Adult Health And Mortality Among Individuals From Two U.S. Documented Skeletal Collections, Late 19Th To Early 20Th Centuries, Rhonda Coolidge

USF Tampa Graduate Theses and Dissertations

Although the association between social inequality and poor adult health is well established, the mechanisms by which inequality is translated into poor adult health are less clear. Increasingly, evidence suggests that many adult health problems and health disparities have their origins in early life; the developmental origins of health and disease (DOHaD) hypothesis provides an explanatory mechanism linking adverse early life conditions with permanent structural or functional changes that increase the risk for disease. This hypothesis is consistent with bioarchaeological research noting reduced lifespan among individuals exhibiting signs of childhood stress.

The principal aim of this dissertation is to contribute …
