Cardioembolic stroke: An update on etiology, diagnosis and management
Leary Megan,Caplan Louis
Annals of Indian Academy of Neurology , 2008,
Abstract: Stroke and ischemic heart diseases are among the most common causes of death and disability throughout the world. Even more worrisome is the suggestion that stroke rates may further increase in certain developing nations. The purpose of this article is to review the particular subtype of stroke known as cardioembolic stroke. A cardioembolic stroke occurs when the heart pumps unwanted materials into the brain circulation, resulting in the occlusion of a brain blood vessel and damage to the brain tissue. The etiology, clinical manifestations, diagnosis and management of cardioembolic stroke are reviewed.
Teaching Feminist Poststructuralism: Founding Scholars Still Relevant Today  [PDF]
Megan Aston
Creative Education (CE) , 2016, DOI: 10.4236/ce.2016.715220
Abstract: This article presents the experiences of one academic educator/researcher learning about and ultimately teaching feminist poststructuralism (FPS) over 20 years. Ideas from foundational postructural and feminist theorists such as Foucault, Butler, Scott and Weedon are presented and brought together into to a particular understanding of FPS. A discussion of how FPS is applied to health education and research will be presented along with clinical examples. After many years of mentoring and teaching students and colleagues about FPS, the author has created a general guide for beginners to help them use FPS in research and practice. This guide has successfully been used with students and colleagues in Canada as well as with colleagues in Tanzania.

Abstract: We characterized soil communities in the Mojave Desert across an elevation gradient. Our goal was to test the hypothesis that as soil quality improved with increasing elevation (due to increased productivity), the diversity of soil prokaryotes and nematodes would also increase. Soil organic matter and soil moisture content increased with elevation as predicted. Soil salinity did not correlate to elevation, but was highest at a mid-gradient, alluvial site. Soil nematode density, community trophic structure, and diversity did not show patterns related to elevation. Similar results were obtained for diversity of bacteria and archaea. Relationships between soil properties, nematode communities, and prokaryotic diversity were site-specific. For example, at the lowest elevation site, nematode communities contained a high proportion of fungal-feeding species and diversity of bacteria was lowest. At a high-salinity site, nematode density was highest, and overall, nematode density showed an unexpected, positive correlation to salinity. At the highest elevation site, nematode density and species richness were attenuated, despite relatively high moisture and organic matter content for the soils. Our results support emerging evidence for the lack of a relationship between productivity and the diversity of soil nematodes and prokaryotes.
Remember the Titans: A Theoretical Analysis
Rameca Leary
Journal of Arts and Humanities , 2013,
Abstract: This paper addresses a pivotal time in American history, when a 1971 Supreme Court mandate required southern school districts to end segregation (Daugherity, 2011). In Alexandria, Virginia, the merger of three rival high schools yielded a racially diverse football team and coaching staff. Beforehand, blacks and whites had their own schools. Many wondered how the new T.C. Williams Titans football team would fare. This paper takes an in-depth look at the film, Remember the Titans, which is based on this story. It analyzes the film using Gordon Allport’s (1954) Intergroup Contact Theory to assess how people from different backgrounds interact within group settings. It explores how communication barriers and the absence of knowledge can lead to ignorance. A 21st century legacy is also discussed, including ideas for further research.
The structure of pleasant ideals
Christopher Leary
Mathematics , 1993,
Abstract: Normal ideals on regular uncountable cardinals are familiar objects. We investigate ideals that are pleasant--while a normal ideal is closed under arbitrary diagonal unions, a pleasant ideal is closed only under diagonal unions indexed by sets that are elements of the ideal. We show any selective ideal extending the nonstationary ideal must be normal.
Evaluating Displayed Depression Symptoms on Social Media Sites  [PDF]
Megan A. Moreno, Erin Kelleher, Megan Pumper
Social Networking (SN) , 2013, DOI: 10.4236/sn.2013.24018

Social networking sites (SNSs) are immensely popular and allow for display of personal information, including references to depression. Evaluating displayed content on a SNS for research purposes requires a systematic approach and a precise data collection instrument. The purpose of this paper is to describe one approach to the development of a research codebook for depression so that others may develop and test their own codebooks for use in SNS research. The depression SNS research codebook was grounded in ethics, theory and clinical criteria.The key elements in the codebook developmental process included an iterative team approach to develop variables of interest and data collection sheet layout. Training protocols involve coding practice and reliability assessments. Interrater reliability remains a critical assessment tool. Codebook successes include consistently high interrater reliability. Challenges include time investment in coder training, SNS server changes, and social or cultural norms regarding public displays of mental health. We provide detailed information about a systematic approach to codebook development so that other researchers may use this structure to develop and test their own codebooks for use in SNS research. Future directions for the codebook include expanding areas of interest such as anxiety or other depression evaluation criteria, and expansion to other SNSs such as Twitter.

Elevated Stream Pathogenic Indicator Bacteria Concentrations in Livestock Grazing Areas across a Single National Forest  [PDF]
Lindsey Myers, Megan Fiske, Megan Layhee
Natural Resources (NR) , 2017, DOI: 10.4236/nr.2017.810042

Livestock presence in proximity to forest streams has been shown to contribute pathogenic bacteria in excess of water quality standards established to protect human health. However, the degree to which livestock fecal contamination in streams on national forest lands is either a limited or a potentially widespread occurrence is still debated. This study provides additional insight into the matter. We analyzed water in small streams near known cattle grazing areas within the Stanislaus National Forest in the Sierra Nevada, California from 2012 to 2016. Fourteen stream sites were sampled before and after cattle were released onto the forest (four of these sites were sampled across multiple years) to compare indicator bacteria concentrations (fecal coliform—FC, Escherichia coli—EC) to standards established for recreational contact for surface waters. One control site was also sampled. There were 194 water quality violations of either state or federal regulatory standards for recreational contact, all of which occurred once cattle were on the forest. Mean (max) FC and EC concentrations were on orders of magnitude higher after cattle were released onto the forest [FC 1307 (30,000) and EC 1033 (17,000) MPN/100 mL] than during the time period before cattle were on the forest [FC 19 (220) and EC 17 (220) MPN/100 mL; FC, F1,210 = 105, p < 0.001; EC, F1,210 = 85.5, p < 0.001]. In addition, the presence of cattle, visual evidence of recent cattle-related disturbances, and sampling week were important predictor variables of FC and EC. These findings support the link between cattle presence and increased levels of stream pathogenic bacteria, and also demonstrate that stream pathogenic bacteria pollution occurs widely across the forest. This research indicates the need to consider alternative range management practices to better protect water quality and human health.

Factors Promoting Positive Adaptation and Resilience during the Transition to College  [PDF]
Kevin A. Leary, Melissa E. DeRosier
Psychology (PSYCH) , 2012, DOI: 10.4236/psych.2012.312A180

The transition to college can be a difficult time as students adjust to new social and academic demands while adapting to new living circumstances in a collegiate environment. The ability of students to cope with the stress of such a transition and display positive outcomes despite challenges has important implications for psychosocial well-being as well as academic success. The present study examined the relative impact of four domains that have been shown to promote resilience in the face of stress in order to determine the extent to which each factor predicted student stress independent of all other factors. First-year college students from four universities completed measures assessing their perceived level of stress as well as their social connectedness, self-care behaviors, cognitive style, and life skills. Results revealed that social support and cognitive styles characterized by optimism significantly and uniquely predicted lower stress among students. Findings are discussed in relation to the development of university-based programs to promote the skills and characteristics that are most likely to result in positive outcomes for students during the transition to college.

Regularities in Sequences of Observations  [PDF]
Mahkame Megan Khoshyaran
Open Journal of Statistics (OJS) , 2012, DOI: 10.4236/ojs.2012.24049
Abstract: The objective of this paper is to propose an adjustment to the three methods of calculating the probability that regularities in a sample data represent a systemic influence in the population data. The method proposed is called data profiling. It consists of calculating vertical and horizontal correlation coefficients in a sample data. The two correlation coefficients indicate the internal dynamic or inter dependency among observation points, and thus add new information. This information is incorporated in the already established methods and the consequence of this integration is that one can conclude with certainty that the probability calculated is indeed a valid indication of systemic influence in the population data.
The Impact of Vehicular Networks on Urban Networks  [PDF]
Mahkame Megan Khoshyaran
Journal of Transportation Technologies (JTTs) , 2014, DOI: 10.4236/jtts.2014.44027
Abstract: The objective of this paper is to study the impact of a vehicular network on a physical (road) network consisting of several intersections controlled by traffic lights. The vehicular network is considered to be a random graph superimposed on a regular Hamiltonian graph. The two graphs are connected by hyperlinks. The evolution of traffic at intersections given the existence of vehicular networks is measured by the method of reflective triangles.
