Challenging The “Man” In Mangroves: The Missing Role Of Women In Mangrove Conservation, Alyssa L. Bosold Jan 2012

Challenging The “Man” In Mangroves: The Missing Role Of Women In Mangrove Conservation, Alyssa L. Bosold

Student Publications

Mangroves provide valuable ecosystem services including carbon sequestration, pollution filtration, and protection from tsunamis, tropical storms, and coastal erosion. They also supply coastal communities with important natural resources like firewood, medicine, timber, honey, and fodder for livestock. Unfortunately, the world’s mangroves are rapidly degrading due to rising coastal population, climate change, and destruction for coastal development, agriculture, and aquaculture. Considering their value for the environment and coastal communities, mangrove conservation should become a priority and effort must be invested to find new and successful methods for conserving mangrove ecosystems. As it has proven effective in other conservation contexts, a gendered …

Surviving Stem: Mentoring, Self-Effiacay And Career Intentions Of Female Graduate Students In Science, Technology, Engineering, And Math, Elizabeth Allyne Yost

All ETDs from UAB

The state of women in STEM (Science, Technology, Engineering, and Math) is not equitable to that of their male counterparts. While great strides have been taken in the last few years, many areas of STEM are still unable to draw equitable numbers of women into the academy. One way to encourage women to enter in and remain in the academy is through mentoring. Through mentoring, women are able to see that a career path is possible for them and better learn how to navigate the structure of the academy. Mentoring has also been shown to increase self-efficacy, which the Social …

Simulation Of Bridge Weigh-In-Motion System Integrated With Bridge Safety, Zhisong Zhao Jan 2012

Simulation Of Bridge Weigh-In-Motion System Integrated With Bridge Safety, Zhisong Zhao

All ETDs from UAB

Bridge weigh-in-motion system (B-WIM) testing is a popular technology in bridge applications. The B-WIM system can track extensive information about loading conditions to which bridges are subjected, and engineers can evaluate the responses of bridges and assess their performance relative to the safety index and serviceability. Currently, the USA, significant numbers of bridges are considered defective and are eligible for retrofits and replacement. Optimized safety evaluation of old and defective bridges is urgent in response to reduced government funding for infrastructure improvements. To conduct safety evaluations of existing bridges without interrupting traffic, the B-WIM system is the first choice for …

Beyond The Excuses: The Effect Of Culturally Responsive Pedagogy On African American Male Students, Kelly Cousette Jan 2012

Beyond The Excuses: The Effect Of Culturally Responsive Pedagogy On African American Male Students, Kelly Cousette

All ETDs from UAB

ABSTRACT Nearly 30 years have elapsed since the National Assessment of Educational Progress reported that America's public education system is failing African American male students. These widely used statistics state that compared to their White and African American female counterparts, African American male students underperform in nearly all educational measures (i.e. GPA, standardized test scores, graduation and dropout rates, etc.). The majority of the research on this academic achievement gap has focused on deepening our understanding of the barriers to educating African American males. While understanding the problem is a logical first step to resolving any dilemma, research on this …

Executive Functioning And Behavior Among Very Low Birth Weight Children At School-Age, Desiree Maria De Jong Jan 2012

Executive Functioning And Behavior Among Very Low Birth Weight Children At School-Age, Desiree Maria De Jong

All ETDs from UAB

Children born prematurely and/or with low birth weight (LBW) are at significantly higher risk than their full-term peers for developing cognitive, behavioral, attention, and executive functioning (EF) difficulties by school-age. The difficulties experienced by this population typically persist well into adolescence and vary as a function of birth weight, with infants weighing less at significantly higher risk for long-term problems. However, there is little consensus with regard to the specific factors that place preterm and LBW children at greatest risk for EF and behavioral impairments. A primary purpose of the current study was to examine the degree to which neonatal/ …

An Information Theory Based Representation Of Software Systems And Design, Zekai Demirezen Jan 2012

An Information Theory Based Representation Of Software Systems And Design, Zekai Demirezen

All ETDs from UAB

Software designers can benefit from the experience of engineering designers and information theory formalism. Every design starts with uncertainty and the art of software design involves uncertainty reduction. Information theory enables software designers to adopt a systems view that facilitates intellectual control over a given software design. Since design imposes organization through successive transformations in reaching the final product, it is possible to formalize design with information theory. We investigated software design as a hierarchical decomposition of design spaces. We realized that before initiating the software design process there is minimal organization, representing higher entropy. The design decisions carrying out …

Screen-Printing Of Ferrite Magnetic Nanoparticles Produced By Carbon Combustion Synthesis Of Oxides, Karen S. Martirosyan, Gamage Dannangoda, Eduard Galstyan, Dmitri Litvinov

Physics & Astronomy Faculty Publications

The feasibility of screen-printing process of hard ferrite magnetic nanoparticles produced by carbon combustion synthesis of oxides (CCSO) is investigated. In CCSO, the exothermic oxidation of carbon generates a smolder thermal reaction wave that propagates through the solid reactant mixture converting it to the desired oxides. The complete conversion of hexaferrites occurs using reactant mixtures containing 11 wt. % of carbon. The BaFe12O19 and SrFe12O19 hexaferrites had hard magnetic properties with coercivity of 3 and 4.5 kOe, respectively. It was shown that the synthesized nanoparticles could be used to fabricate permanent magnet structures by consolidating them using screen-printing techniques.

On The Synthesis And Physical Properties Of Iron Doped Sno2 Nanoparticles, X. Wei, R. Georgescu, N. Ali, I. Morjan, T. A. George, F. Dumitrache, R. Birjega, Mircea Chipara

Physics & Astronomy Faculty Publications

The synthesis of iron doped tin oxide by pulsed laser pyrolysis is reported. The as obtained nanoparticles have a dominant SnO2 phase (as revealed by Wide Angle X-ray Scattering), with particles of the order of 10 nm. The doping with iron or iron oxide triggers magnetic properties as confirmed by SQUID experiments. EDX measurements supported the presence of Fe while Wide Angle X-ray Scattering failed to sense any iron or iron-oxide phase. It is concluded that Fe is well dispersed within the tin-oxide nanoparticles. The coercitive field has a complex dependence on the Fe/Sn content suggesting that the magnetization is …

The Characterization Of Virgo Data And Its Impact On Gravitational-Wave Searches, J. Aasi, J. Abadie, Matthew Benacquista, G. Cagnoli, Teviet Creighton, Mario C. Diaz, Soma Mukherjee, Volker Quetschke, Malik Rakhmanov, Joseph D. Romano, Cristina V. Torres

Physics & Astronomy Faculty Publications

Between 2007 and 2010 Virgo collected data in coincidence with the LIGO and GEO gravitational-wave (GW) detectors. These data have been searched for GWs emitted by cataclysmic phenomena in the universe, by non-axisymmetric rotating neutron stars or from a stochastic background in the frequency band of the detectors. The sensitivity of GW searches is limited by noise produced by the detector or its environment. It is therefore crucial to characterize the various noise sources in a GW detector. This paper reviews the Virgo detector noise sources, noise propagation, and conversion mechanisms which were identified in the three first Virgo observing …

The Biodiversity Of Thermoduric Bacteria Isolated From Whey, Joseph Meade, Seamus Fanning, Kevinia Mcgill, Ciara Walsh Jan 2012

The Biodiversity Of Thermoduric Bacteria Isolated From Whey, Joseph Meade, Seamus Fanning, Kevinia Mcgill, Ciara Walsh

Articles

Thermoduric gram-positive bacteria are indigenous in milk, cheese, whey and other dairy products. They are capable of surviving heat processes and can result in quality defects and a shortened product shelf life. In Ireland, premium products such as whey protein concentrate (WPC) are often adversely affected by these microorganisms, particularly during the winter months.A high bacterial count in the WPC can result in the product being sold at a lower grade, with an overall loss of revenue for the manufacturer. This study recovered thermoduric bacterial isolates (n = 140) from an Irish WPC process during the months of November–February.Using molecular …

Effect Of Different Rehydration Temperatures On The Moisture And Phytochemical Constituents Of Dried Edible Irish Brown Seaweed., Sabrina Cox, Shilpi Gupta, Nissreen Abu-Ghannam

Articles

The effect of temperature (20, 40, 60, 80 and 100 °C) on the rehydration kinetics and phytochemical constituents of dried edible Irish brown seaweed, Himanthalia elongata, were studied. The moisture content of fresh and dried seaweed was 4.07 and 0.07 g water/g dry basis, representing a 98.1% reduction in water content. All rehydration moisture curves had a clear exponential tendency, and it was observed that the rehydration time decreased when temperature was increased. Although restoration of the product to its original moisture content was achieved, rehydration resulted in losses in phytochemical content. Moisture equilibrium was achieved fastest at 100 °C …

Climate Change Adaptation In Mauritius: Considering The Role Of Institutions, Matthew Gray, Bhanooduth Lalljee Jan 2012

Climate Change Adaptation In Mauritius: Considering The Role Of Institutions, Matthew Gray, Bhanooduth Lalljee

East Africa

Adaptation to climate change is critical in countries like Mauritius which, despite contributing a minute percentage to the world’s emissions, is disproportionately vulnerable to their impacts. Rising temperatures are exacerbating the problems of coral reef bleaching, soil and beach erosion, a greater risk of drought and flash floods, intensifying tropical storms, sea level rise and biodiversity impacts. Projections of accelerated warming only increase the urgency for a coordinated framework of adaptive governance in Mauritius. The nature of adaptation needed will require a complex, long-term, and interdisciplinary process of widespread engagement, necessitating effective institutions with shared responsibilities. This paper describes how …

Proximate Retribution, Meghan J. Ryan Jan 2012

Proximate Retribution, Meghan J. Ryan

Faculty Journal Articles and Book Chapters

An essential element of the theory of retribution has been missing from courts’ and legal scholars’ analyses. While they have outlined a number of varieties of the theory and fleshed out their nuances, courts and scholars have largely neglected to examine which harms flowing from a criminal offender's conduct should be considered in determining that offender’s desert. The more remote harms caused by an offender’s conduct, such as the effects of his offenses on the families and friends of his victims or the effects of criminal conduct on society in general, are pervasive in communities across the nation.

A Yeast Model For High Throughput Screening Of Gene-Gene Interactions Relevant To Cftrδf508 Protein Biogenesis, Jingyu Guo Jan 2012

A Yeast Model For High Throughput Screening Of Gene-Gene Interactions Relevant To Cftrδf508 Protein Biogenesis, Jingyu Guo

All ETDs from UAB

Much remains unknown about gene interaction in the context of human disease. In cystic fibrosis (CF) a single mutation of the cystic fibrosis transmembrane conductance regulator (CFTR-deltaF508) accounts for most disease. In cell models, CFTR-deltaF508 causes defective protein biogenesis and degradation rather than proper trafficking to the plasma membrane where CFTR normally functions in ion transport. Numerous genes function in the biogenesis of CFTR and influence the fate of CFTR-deltaF508 in cell models. However it is not known whether natural genetic variation in such genes contributes to disease severity in patients. Moreover, there is no easy way to predict how …

Taboo: A Novel, George Sawaya Jan 2012

Taboo: A Novel, George Sawaya

All ETDs from UAB

TABOO is a novel aimed at capturing the hardships of contemporary American society, especially its youth. The ongoing financial crisis of the early 2000s takes its toll on nearly every American. Budding, college educated youths find themselves somewhat disenfranchised in modern America. TABOO, through its hard-luck protagonist Conrad Kemp and his struggle to make a living as a freelance journalist in New York City, considers aspects of freedom in an ailing America. So too, the novel focuses on ephemeral freedoms, or temporary escapes, most of which are not always publicly palatable. Our taboo activities, sexual or innocent, provide a sense …

School of Engineering, Computing and Mathematics

We calculate on GPUs the disconnected diagrams associated with the nucleon form factors and moments of generalized parton distributions using Nf=2+1+1 twisted mass fermions. We employ the truncated solver method (TSM) for estimating the all-to-all propagators. Due to the fact that the TSM involves many low precision stochastic estimators, the usage of GPUs is essential to perform efficiently the contractions and the inversions.

Young Children Consider Merit When Sharing Resources With Others, Patricia Kanngiesser, Felix Warneken Jan 2012

Young Children Consider Merit When Sharing Resources With Others, Patricia Kanngiesser, Felix Warneken

School of Psychology

Merit is a key principle of fairness: rewards should be distributed according to how much someone contributed to a task. Previous research suggests that children have an early ability to take merit into account in third-party situations but that merit-based sharing in first-party contexts does not emerge until school-age. Here we provide evidence that three- and five-year-old children already use merit to share resources with others, even when sharing is costly for the child. In Study 1, a child and a puppet-partner collected coins that were later exchanged for rewards. We varied the work-contribution of both partners by manipulating how …

A Longitudinal Study Of Teaching Practice And Early Career Decisions: A Cautionary Tale, Marilyn Cochran-Smith, Patrick Mcquillan, Kara Mitchell Viesca, Dianna Gahlsdorf Terrell, Joan Barnatt, Lisa D’Souza, Cindy Jong, Karen Shakman, Karen Lam, Ann Marie Gleeson

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Although the turnover rate among beginning teachers has been a major concern for some time, most studies do not link teacher retention with teaching practice. In contrast, this study looks specifically at career decisions coupled with practice. Guided by a view of teaching as social and cultural practice, the study used multiple qualitative data sources, including extensive observations, interviews, and samples of teachers’ and students’ work. Based on within and cross-case analysis of 15 cases at four distinct time points within a 5-year period, the authors identified multiple patterns of teaching practice linked to early career decisions, which reflect considerable …
