How Children Quantify Area, James Wilder

All ETDs from UAB

The Common Core State Standards (2010) requires the quantification of area with the formula for a rectangle, length multiplied by width. More specifically, according to the Standards, third graders are to find the area of a rectangle by tiling it and showing that the area is the same as it would be from multiplying the side lengths. Is this a realistic expectation for third graders? The present study focuses on how children quantify area after receiving instruction on length x width, when asked to compare two rectangles having different dimensions. Fourth, sixth, and eighth graders were interviewed to find out …

A Mixed Methods Study Of Health Literacy And Its Role In Hpv Vaccine Uptake Among College Students, Michelle Sharonda Williams

All ETDs from UAB

Health literacy includes the ability to understand and process written and spoken health information, and numbers and calculations related to health information. Low health literacy is associated with negative health outcomes, and poor patient-provider communication. In order to advance health literacy research, there is a need to assess health literacy comprehensively and to develop an understanding of how health literacy impacts people at various stages of their lives. A sequential explanatory mixed methods study was conducted to assess college students' health literacy. During the quantitative phase, the Short Test of Functional Health Literacy in Adults (S-TOFHLA), the Newest Vital Sign …

Combined Effects Of Corexit Ec 9500a With Secondary Abiotic And Biotic Stressors In The Rotifer Brachionus Plicatilis, Michael Britt Williams

All ETDs from UAB

Following the Deepwater Horizon oil spill the dispersant Corexit EC 9500A (C-9500) was applied to facilitate rapid oil degradation. C-9500 toxicity has been evaluated on a number of marine species; however, many of these studies do not account for environmental conditions that may increase negative outcomes related to dispersant exposure in the wild. We examined lethality and behavioral effects of C-9500 exposure on the model marine zooplankton Brachionus plicatilis. We also evaluated interactions of abiotic and biotic stressors that may alter outcomes of exposure. C-9500 exposure at standard husbandry conditions (17.5ppt, 24°C, 200 rotifer*ml-1 density) produced a 24 hr median …

Lost And Found - David Hoffman And The History Of American Legal Ethics, Michael S. Ariens

Faculty CLE

David Hoffman was a successful Baltimore lawyer who wrote the first study of American law in 1817 and authored the first maxims of American legal ethics. Yet for more than a century after his death, Hoffman was a forgotten figure to American lawyers. Beginning in the late 1970s, Hoffman was re-discovered, and his writings on legal ethics have been favorably cited.

How and why was Hoffman “lost” to American law for over a century, and why he was “found”? Hoffman was lost to history because his view of ethics was premised on republican virtue, specifically the concept of honor. A …

Fernandes, Kerstin Hund-Rinke, Diana Boraschi, Karin Aschberger, Stefania Gottardo, Frank Von Der Kammer, Dana Kühnel, Danail Hristozov, Antonio Marcomini, Lucia Migliore

Articles

Bringing together topic-related European Union-(EU)-funded projects, the so-called “NanoSafety Cluster” aims at identifying key areas for further research on risk assessment procedures for nanomaterials (NM). The outcome of NanoSafety Cluster Working Group 10, this commentary presents a vision for concern-driven integrated approaches for the (eco-)toxicological testing and assessment (IATA) of NM. Such approaches should start out by determining concerns, i.e. specific information needs for a given NM based on realistic exposure scenarios. Recognized concerns can be addressed in a set of tiers using standardized protocols for NM preparation and testing. Tier 1 includes determining physico-chemical properties, non-testing (e.g. structure …

Effect Of Substrate Choice And Tissue Type On Tissue Preparation For Spectral Histopathology By Raman Microspectroscopy, Hugh Byrne, Leanne M. Fullwood, Dave Griffiths, Katherine Ashton, Timothy Dawson, Robert W. Lea, Charles Davis, Franck Bonnier, Matthew J. Baker

Articles

Raman spectroscopy is a non-destructive, non-invasive, rapid and economical technique which has the potential to be an excellent method for the diagnosis of cancer and understanding disease progression through retrospective studies of archived tissue samples. Historically, biobanks are generally comprised of formalin fixed paraffin preserved tissue and as a result these specimens are often used in spectroscopic research. Tissue in this state has to be dewaxed prior to Raman analysis to reduce paraffin contributions in the spectra. However, although the procedures are derived from histopathological clinical practice, the efficacy of the dewaxing procedures that are currently employed is questionable. Ineffective …

Weight-Loss Interventions Performed To Reduce The Risk Of Obesity-Related Complications, Victoria Stephanie Stewart

Walden Dissertations and Doctoral Studies

The management of obesity before a woman conceives is one of the most effective efforts a woman can take in decreasing her risk of obesity-related complications during pregnancy. Evidence supports the idea that maternal obesity influences maternal and fetal outcomes, leading to maternal and fetal morbidities. Physicians acknowledge the importance of screening women for obesity, but many do not refer patients for weight-loss therapy. In this study, the health belief model was used to explore the associations between participants' obesity risk of complications during pregnancy, the number of weight-loss interventions they attempted to implement prior to pregnancy, and how they …

Implicit Category Priming Capacity, Edward Paulus Hahn

Walden Dissertations and Doctoral Studies

Past research has shown that accessing a memory allows faster subsequent access to the memory activated as well as to related information (priming). There has been much research devoted to implicit category priming (unintentional priming of a category of information), but this research has not determined the number of categories that can be implicitly primed simultaneously. The goal of the present quantitative study was to address that gap. Twenty participants (ages 27-54 years, M=44 years), who volunteered through an online participant pool, were presented with 2 tasks over the Internet. A scrambled phrase task implicitly primed 5 unrelated categories and …

23andme, The Food And Drug Administration, And The Future Of Genetic Testing, Patricia Zettler, Jacob S. Sherkow, Henry Greely

Other Publications

On November 22, 2013, the US Food and Drug Administration (FDA) effectively halted health-related direct-to-consumer genetic testing in the United States by sending a warning letter to 23andMe, the leading company in the field, directing it to stop providing such testing. The FDA acted as the era of widespread, clinical use of DNA sequencing rapidly approaches. The agency’s action will contribute to changes in which genetic tests are offered to patients and how testing is provided.

Fatigue Testing Of Straight And Angled Abutments In A High Torque Dental Implant System, Rana M. Atieh

All ETDs from UAB

Root form dental implants are a common solution used today to replace missing teeth. However current designs still suffer from a number of limitations. Angled abutments are used for incisors, where maximum human bite forces are normally < 200N, while straight abutments are used for molars subjected to higher forces > 200 N. The aim of this study was to evaluate the mechanical performance of a novel dental implant system by fatigue testing straight and 15-degree angled abutments. It was hypothesized that the novel thread design will dissipate the load evenly throughout the implant allowing the system to withstand normal chewing forces. Implants with 4.2mm diameter were tested according to ISO 14801 in specimen …

A Process-Oriented Measure Of Habit Strength For Moderate-To-Vigorous Physical Activity, J. Robert Grove, Irja Zillic, Nikola Medic

Research outputs 2014 to 2021

Habitual action is an important aspect of health behaviour, but the relevance of various habit strength indicators continues to be debated. This study focused specifically on moderate-to-vigorous physical activity (MVPA) and evaluated the construct validity of a framework emphasizing patterned action, stimulus-response bonding, automaticity, and negative consequences for nonperformance as indicators of habit strength for this form of exercise. Methods: Upper-level undergraduates (N = 124) provided demographic information and responded to questionnaire items assessing historical MVPA involvement, current MVPA involvement, and the four proposed habit strength dimensions. Factor analyses were used to examine the latent structure of the habit strength …

Teachers And Teacher Aides Initiating Five-Year-Olds Into Science, Anne M. Thwaite

Apprenticing children into discourses necessary for success at school begins at a very early age. In this paper I look at five-years-olds being introduced to Science and Technology while at the same time being involved in talk around literacy. The various adults who surround the children engage differentially in talk and action while merging the discourses of literacy and science. Data for this study were obtained during the course of the project ‘Early literacy through science in Indigenous and culturally diverse communities’, funded by Edith Cowan University in Australia from 2009–2010, in which the author was involved as a researcher. …

Carer Experiences With Rehabilitation In The Home: Speech Pathology Services For Stroke Survivors, Katy Stewart, Natalie Ciccone, Elizabeth Armstrong

Research outputs 2014 to 2021

Caring for a stroke survivor can be a complex role with carers at an increased risk of mental health difficulties. Early supported discharge from hospital with rehabilitation in the home (RITH) allows stroke survivors to return home at an earlier stage in the recovery process, potentially placing an extra burden on carers. Being involved in intensive therapy,in the home, in the early days post-stroke may be difficult with the role and experiences of carers in RITH being underresearched. This paper identifies the roles, experiences and preferences of ten carers of stroke survivors with dysarthia and dysphagia. Many carers were involved …

Knowledge, Attitude, Lifestyle Practices, And Quality Of Life In Sporadic Lymphangioleiomyomatosis Patients, Shahpar Vafamand

Walden Dissertations and Doctoral Studies

Lymphangioleiomyomatosis (LAM) is a rare lung disease recognized by abnormal growth of smooth muscle cells proliferating in lungs parenchyma, developing benign tumors, migrating to the other organs, and ultimately leading to respiratory failure and death. Despite existing literature mainly on clinical aspects of LAM, there is a gap of literature in regards to the knowledge, attitude, and lifestyle practices (KAPs) of LAM patients and their effects on their quality of life. The purpose of this quantitative study was to investigate the KAPs of the sporadic LAM patients as measured by the Bristol Chronic Obstructive Pulmonary Disease Knowledge Questionnaire, Beliefs and …

The Dignity Of The Human Person: Catholic Social Teaching And The Practice Of Criminal Punishment, Dora W. Klein

Faculty Articles

The moral foundation that supports the Catholic Church's opposition to the death penalty is wide and deep. This Article proposes that despite the oft-repeated maxim that "death is different," the same foundation that supports efforts to abolish the death penalty can also support those who seek to achieve other reforms in the practice of criminal punishment.

Assessing System Congruence By Analyzing The Relationship Between Employee And Patient Driven Outputs, Timothy J. Harlin

All ETDs from UAB

Patients are at risk for employee driven preventable adverse events during hospital stays. These adverse events are varied and include such things as medication errors, pressure ulcers, hospital acquired infections, and falls. Preventable adverse events continue at alarming frequency despite significant academic, regulatory, and management attention to the topic over the past 14 years since the Institute of Medicine's (IOM) To Err is Human report. In addition to being at risk for preventable adverse events, patients experience aspects of the health care system such as ease of access, employee attitude, skill and efficiency of staff, and perceived value. Although purporting …

An Examination Of The Services That Contribute To Positive Vocational Outcomes In Adults With Developmental Disabilities, Abbey N. Harris

All ETDs from UAB

One of the most pressing issues concerning persons with developmental disabilities is making sure their needs are met once they reach adulthood. As adults, they should have the abilities and skills to be as independent as possible and to be contributing members of society. Without the proper services and help, though, this may not be possible for a large portion of this population. Research suggests that supportive employment services alone may not be enough to meet their unique vocational needs and to improve the likelihood of their achieving personal and financial independence. The purpose of this study was to determine …

Understanding Non-Helical Nuclease Resistant Dnas And Their Roles In Tlr9 Mediated Cellular Invasion, Katherine Leigh Hayden

All ETDs from UAB

Non-helical DNA structures such as hairpins and G-quadruplexes found in the non-coding regions of chromosomes have been implicated in a number of biological processes such as control of genetic expression and in dysregulation causing diseases such as cancer. Recent studies from our laboratory have found that apoptotic DNA released from cancer cells, a synthetic G-quadruplex forming telomeric sequence, and a highly thermal stable DNA hairpin can induce an invasion response from a variety of cancer cell types. This invasion has been demonstrated to be mediated through a toll-like receptor protein found within the endosomes of the cell. We hypothesize that …
