Estimating The Sediment Flux And Budget For A Data Limited Rift Valley Lake In Ethiopia, Alemu O. Aga, Assefa M. Melesse

Department of Earth and Environment

Information on sediment concentration in rivers is important for the design and management of reservoirs. In this paper, river sediment flux and siltation rate of a rift valley lake basin (Lake Ziway, Ethiopia) was modeled using suspended sediment concentration (SSC) samples from four rivers and lake outlet stations. Both linear and non-linear least squares log–log regression methods were used to develop the model. The best-fit model was tested and evaluated qualitatively by time-series plots, quantitatively by using watershed model evaluation statistics, and validated by calculating the prediction error. Sediment yield (SY) of ungauged rivers were assessed by developing and using …

American Labour’S Cold War Abroad: From Deep Freeze To Détente, 1945-1970 By Anthony Carew: A Review Essay, Kim Scipes

Class, Race and Corporate Power

With Anthony Carew’s new book, we are much closer to having a definitive empirical history of US Labor’s foreign policy operations across this 25-year period, including the AFL’s, the CIO’s, and the AFL-CIO’s foreign operations between 1945 and 1970. Based on extensive archival research and personal interviews by a careful and extremely meticulous scholar, we now have more details than all-but-a-few specialists may want to know. While not the first book to cover this subject, nor particular aspects of this subject, Carew’s intervention adds greatly to what we know and, in a number of ways, re-establishes the groundwork from which …

Sex Differences In Gains Among Hispanic Pre-Kindergartners’ Mental Rotation Skills, Carla Abad, Rosalie Odean, Shannon M. Pruden

Department of Psychology

The current study explores change in mental rotation skills throughout the pre-kindergarten year in a Hispanic population to better understand the development of early sex differences in mental rotation. Ninety-six Hispanic children (M = 4 years 8 months) completed a mental rotation task at the beginning and end of pre-kindergarten. Results suggest Hispanic boys and girls differed in gains on mental rotation ability, with boys improving significantly more than girls during pre-kindergarten on a mental rotation task. This study highlights the significance of studying mental rotation abilities in a Hispanic population of pre-kindergarten aged children and suggests the importance …

Florida's Pillar Coral (Dendrogyra Cylindrus): The Roles Of The Holobiont Partners In Bleaching, Recovery, And Disease Processes, Cynthia Fairbank Lewis

FIU Electronic Theses and Dissertations

The iconic pillar coral, Dendrogyra cylindrus, is one of five Caribbean species listed in 2014 under the US Federal Endangered Species Act because of its extreme low abundance and continued decline in US waters. Until recently, little was known about the demographics or genetic diversity of Florida’s D. cylindrus population. This study represents the first time two holobiont partners (coral animal and associated photosynthetic algal endosymbionts) have been closely examined, spatially and temporally, in this little-studied species. The aim was to explore the influences of coral animal genotypes, mutualistic photosynthetic algal strains, and hyperthermal stress on bleaching and …

Genocide In The Modern Age: State-Society Relations In The Making Of Mass Political Violence, 1900-2015, Zachary Karazsia

FIU Electronic Theses and Dissertations

This dissertation presents a new conceptual framework for understanding genocide and mass political violence. I build upon existing theories of mass violence that take into account motivations for committing mass atrocities, combine these with the task of counting civilian casualties, and propose a new framework based on the perpetrators’ socio-political standing in society. This model develops a four-part typology of perpetrators by examining the level of government participation and societal participation in the process of violence. Four patterns of perpetrators emerge from this deductive assessment of large-scale violence. These mass political violence perpetrator categories are: a) state perpetrators; b) state-society …

The Effects Of Copper Exposure On Fish Locomotion And Predator-Prey Interactions, Tiffany N. Yanez

FIU Electronic Theses and Dissertations

This study determined the effects of the copper water quality criterion (WQC) by the EPA on [1] swimming performance and [2] predator-prey interactions of the Sailfin Molly, across a salinity gradient. Fish acclimated to FW (0 ppt) and 8-ppt saltwater were exposed to 11.3 and 8.44 µg/L Cu for 96 h, respectively. At the end of the exposures, fish swimming performance was determined by using the critical swimming speed, U_crit, the speed at which a fish cannot longer maintain position in the water column. U_critwas then measured again after a 4-week depuration period to determine if …

Direct Observation Of Topoisomerase Ia Gate Dynamics, Maria Mills, Yuk-Ching Tse-Dinh, Keir C. Neuman

Biomolecular Sciences Institute: Faculty Publications

Type IA topoisomerases cleave single-stranded DNA and relieve negative supercoils in discrete steps corresponding to the passage of the intact DNA strand through the cleaved strand. Although type IA topoisomerases are assumed to accomplish this strand passage via a protein-mediated DNA gate, opening of this gate has never been observed. We developed a single-molecule assay to directly measure gate opening of the Escherichia coli type IA topoisomerases I and III. We found that after cleavage of single-stranded DNA, the protein gate opens by as much as 6.6 nm and can close against forces in excess of 16 pN. Key differences …

Geodetic Evidence For Interconnectivity Between Aira And Kirishima Magmatic Systems, Japan, E. Brothelande, F. Amelung, Z. Yunjun, S. Wdowinski

Department of Earth and Environment

It is not known whether clustered or aligned volcanic edifices at the Earth surface have connected magmatic systems at depth. Previously suggested by geological records of paired eruptions, volcano interconnectivity still lacks proper geodetic evidence. Here we use GPS time-series and deformation modeling to show how Aira caldera and Kirishima, two adjacent volcanic centers in Kagoshima graben (southern Japan), interacted during Kirishima unrest in 2011. Whereas Aira caldera had been inflating steadily for two decades, it deflated during the eruption of Kirishima which started with a large-volume lava extrusion. This deflation, which cannot be explained by stress changes, is interpreted …

Modeling The Impact Of The Vehicle-To-Grid Services On The Hourly Operation Of The Power Distribution Grid, Tawfiq Aljohani, Osama Mohammed

Electrical and Computer Engineering Faculty Publications

Electric Vehicles (EVs) impact on the grid could be very high. Unless we monitor and control the integration of EVs, the distribution network might experience unexpected high or low load that might exceed the system voltage limits, leading to severe stability issues. On the other hand, the available energy stored in the EVs can be utilized to free the distribution system from some of the congested load at certain times or to allow the grid to charge more EVs at any time of the day, including peak hours. This article presents dynamic simulations of the hour-to-hour operation of the distribution …

Editorial: Parent, Grandparent, And Sibling Responses To The Death Of An Infant Or Child In Intensive Care, Joanne M. Youngblut, Juanjuan Li

Nicole Wertheim College of Nursing and Health Sciences

The death of a child is a devastating event for most parents and other family members1. However, responses to a child’s death vary by culture, generation, and often the age of the deceased child. For the Chinese, child death is a “bad death” and brings shame to the family2. Filipino parents of a deceased child feel severe guilt after their loss3. In some Caribbean cultures young mothers are prevented from attending the child’s funeral or going to the cemetery by women in the previous generation in the belief that if you “take one to …

Further, a big chunk of time and energy is spent on analyzing these graphs on large compute clusters and/or data-centers. Filtering and refining of data using graph sampling techniques are one of the most effective ways to speed …

Phonological Interaction In Spanish-English Bilinguals: Effects Of Cognate Usage On Voice Onset Time Of Voiced Stops, Sophia Andrea Younes

MA in Linguistics Final Projects

This study compared Spanish-English bilinguals’ and English monolinguals’ VOT values for voiced stops /b, d, g/ in cognates and non-cognates. The data support cross-linguistic interaction in bilinguals' phonologies, and indicate that cognates can interfere with bilinguals’ phonemic distinctions, realized in their phonetic productions.

For voiced stops, English VOT norms generally average 0 to +35 ms, while Spanish VOT norms average -235 to -45 ms. Twenty-six participants (twelve English monolinguals and fourteen early Spanish-English bilinguals) were administered a picture-naming task, balanced for cognate and non-cognate forms. The VOT values of 30 target words per participant and per language were measured.

Ordered Anarchy: The Origins And Evolution Of A Society Of States In South America, 1864-1939, Nicolas Terradas

FIU Electronic Theses and Dissertations

The present dissertation studies why South American states have fought so few wars among one another since their independence in the early 1800s, and why those wars in which they did enter were limited in intensity, casualty rates, number of battles, and overall duration. It offers an extensive review of the literature on South America’s “long peace” and advances two critiques. First, that the existing studies have usually followed either a narrow quantitative definition of war, or a broad qualitative definition of peace. And second, that the literature tends to neglect the relevance of the 19th century in the historical …

The "New" Black In The New South: Negotiating Race And Space In North Carolina's Immigrant Communities, Masonya Joy Bennett

FIU Electronic Theses and Dissertations

This dissertation explores identity and subject formation among black immigrant populations in Charlotte, N.C, a non-traditional gateway city. It interrogates claims made by regional scholars and policy-makers that, due to recent demographic shifts and economic development, Charlotte embodies the “New South”, a designation signifying the transition from an agricultural to a corporation-based economy and from a racially polarized to a multicultural society. Based upon 18 months of ethnographic research utilizing a mixed method approach among immigrants of African descent in the trans-ethnic enclave of East Charlotte, the dissertation focuses on the role of space, place, material culture and affect in …
