Analysis Of Students’ Misconceptions And Error Patterns In Mathematics: The Case Of Fractions, Zoe A. Morales

South Florida Education Research Conference

This study analyzed three fifth grade students’ misconceptions and error patterns when working with equivalence, addition and subtraction of fractions. The findings revealed that students used both conceptual and procedural knowledge to solve the problems. They used pictures, gave examples, and made connections to other mathematical concepts and to daily life topics. Error patterns found include using addition and subtraction of numerators and denominators, and finding the greatest common factor.

The Experience Of “Bottoming”: Considerations For Identity And Learning, Craig M. Mcgill, Joshua Collins

South Florida Education Research Conference

Bottoms—Gay men who prefer to be penetrated, sexually—are more stigmatized than other gay men, and may develop and experience identities differently than other gay, bisexual, or heterosexual men. This paper explores intrinsic dispositions and extrinsic motivations that may lead bottoms to perform and embody psychosocial and sexual identities in intimate, interpersonal, and social contexts.

The Relationship Between Online And In Person Ged Preparatory Courses, Jocelyn Y. Messerschmidt

South Florida Education Research Conference

Courses are taken in order to prepare for the General Educational Development Test. These courses are offered traditionally and virtually. The actual test must be taken in-person regardless of whether an individual took preparatory courses virtually or traditionally. This paper will explore the benefits and obstacles that each method of delivering instruction has.

Users Acceptance Of Online Enrollment Processes In A Higher Education Institution, Luis F. Rodriguez

South Florida Education Research Conference

Little is known about students’ perceptions of online enrollment processes. Student satisfaction is part of the assessment required for accreditation, but evidence suggests that college administrators are oriented to retention and graduation rates rather than to consumer perception. The purpose of this descriptive quantitative study was to develop and validate a model that enables the measurement of online enrollment processes by the analysis of the students’ perceptions. The theoretical framework used to support this study was the process virtualization theory while the conceptual framework was based on Technology Acceptance Model (TAM). TAM is the most valid framework for studying user …

Understanding Ten-Eleven Translocation-2 In Hematological And Nervous Systems, Feng Pan

FIU Electronic Theses and Dissertations

I proposed the study of two distinct aspects of Ten-Eleven Translocation 2 (TET2) protein for understanding specific functions in different body systems.

In Part I, I characterized the molecular mechanisms of Tet2 in the hematological system. As the second member of Ten-Eleven Translocation protein family, TET2 is frequently mutated in leukemic patients. Previous studies have shown that the TET2 mutations frequently occur in 20% myelodysplastic syndrome/myeloproliferative neoplasm (MDS/MPN), 10% T-cell lymphoma leukemia and 2% B-cell lymphoma leukemia. Genetic mouse models also display distinct phenotypes of various types of hematological malignancies. I performed 5-hydroxymethylcytosine (5hmC) chromatin immunoprecipitation sequencing (ChIP-Seq) and RNA …

Background

Intracranial volume (ICV) is an important normalization measure used in morphometric analyses to correct for head size in studies of Alzheimer Disease (AD). Inaccurate ICV estimation could introduce bias in the outcome. The current study provides a decision aid in defining protocols for ICV estimation in patients with Alzheimer disease in terms of sampling frequencies that can be optimally used on the volumetric MRI data, and the type of software most suitable for use in estimating the ICV measure.

Methods

Two groups of 22 subjects are considered, including adult controls (AC) and patients with Alzheimer Disease (AD). Reference measurements …

A new time varying approach for constructing functional connectivity networks (FCNs) of 18 subjects (7 subjects from pediatric control (PC) group and 11 subjects from pediatric epilepsy (PE) group) is implemented by moving a window with overlap to split the EEG signals into a total of …

Morphological And Physiological Responses Of Seagrasses (Alismatales) To Grazers (Testudines: Cheloniidae) And The Role Of These Responses As Grazing Patch Abandonment Cues, Elizabeth A. Lacey, Ligia Collado-Vides, James W. Fourqurean

Department of Biological Sciences

Green sea turtles, Chelonia mydas, are grazers influencing the distribution of seagrass within shallow coastal ecosystems, yet the drivers behind C. mydas patch use within seagrass beds are largely unknown. Current theories center on food quality (nutrient content) as the plant responds to grazing disturbances; however, no study has monitored these parameters in a natural setting without grazer manipulation. To determine the morphological and physiological responses potentially influencing seagrass recovery from grazing disturbances, seagrasses were monitored for one year under three different gazing scenarios (turtle grazed, fish grazed and ungrazed) in a tropical ecosystem in Alcumal Bay, Quintana Roo, Mexico. …

The Argentine Dilemma: “Vulture Funds” And The Risks Posed To Developing Economies, Mine Doyran

Class, Race and Corporate Power

Post-crisis Argentina is a case study of crisis management through debt restructuring. This article examines how Argentina negotiated the external debt in the wake of the sovereign default in December 2001 and now confronts challenges posed by holdout creditors—the so called “vulture funds”. It argues that debt restructuring has put a straitjacket on the national economy, making it virtually impossible for healthy growth short of a break with the international economic order. While Argentina has successfully restructured a $95 billion debt with an unprecedented “hair cut” (around 70% reduction in “net value of debt”), a sustainable growth appears out of …

Czechs Look Back On 1989, A Revolution Betrayed: A Reflection On The Mythology Of The Velvet Revolution, Lukáš Rychetský, Jaroslav Fiala

Class, Race and Corporate Power

Twenty-five years ago today the Velvet Revolution kicked off in what was then Czechoslovakia to bring an end to the one-party government of the Communist Party. This exclusive translation of a feature from the Czech journal A2 Cultural Bi-Weekly explains that the events of 1989 were about more than just Václav Havel, a playwright and leader in the revolution who was elected president in 1990. A generation of unfulfilled promises later, Czechs are struggling to revive the spirit of not only democracy and humanism, but also socialism.

HWCOM Faculty Publications

Alzheimer's disease (AD) is characterized by progressive dysfunction of memory and higher cognitive functions with abnormal accumulation of extracellular amyloid plaques and intracellular neurofibrillary tangles throughout cortical and limbic brain regions. Withania somnifera (WS) also known as ‘ashwagandha’ (ASH) is used widely in Ayurvedic medicine as a nerve tonic and memory enhancer. However, there is paucity of data on potential neuroprotective effects of ASH against β-Amyloid (1–42) (Aβ) induced neuropathogenesis. In the present study, we have tested the neuroprotective effects of Methanol: Chloroform (3:1) extract of ASH and its constituent Withanolide A (WA) against Aβ induced toxicity, HIV-1_Ba-L (clade …
