“When I was a college student, I was struggling in an intimate relationship I was forming, and it got to the point where I had to do something about it. So I went into the counseling center, and that’s what really turned me on—noticing the change within myself and the impact of counseling on the way we view our lives.”

That is the way Dr. Glenn Albright explains how he became interested in psychology in general and in counseling in particular. A native of Albany, New York, Albright received his bachelor’s in biology from Parson College in Iowa, his MS …

Latino And Non-Latino White Parents’ Experiences Raising Their Child With Asd: An Exploratory Study, Nicole Casillas, Debra Vigil, Hui-Ting Wang

The Qualitative Report

There is a dearth of research about the experiences of the Latino population in raising a child with autism spectrum disorder (ASD). This includes a lack of cross-cultural perspectives and perspectives from fathers. Although there are similar experiences in raising a child with ASD among parents, we hypothesize that there will be different experiences due to culture. The current study is an exploratory qualitative research design, where we sought to understand the experiences of Latino and non-Latino White parents who are raising a child with ASD. Results indicated similarities across all families that include: self-efficacy beliefs, challenges, stress and coping, …

Critical Keys To Successful Offender Reentry: Getting A Handle On Substance Abuse And Mental Health Problems, Elaine Gunnison, Jacqueline B. Helfgott

The Qualitative Report

Over the past several decades, all facets of institutional and community corrections have been growing. This growth has resulted in increased numbers of ex-offenders reentering society. While research has emerged on reentry, much of the research has focused on examining reentry failure as opposed to reentry success. Interviews of 40 ex-offenders and community corrections officers were conducted in Washington State to pinpoint what is needed to assist ex-offenders as they reenter society—particularly as it relates to substance abuse and mental health treatment. Results from interviews revealed that ex-offenders need assistance to address substance abuse and mental health issues while incarcerated …

An Examination Of The Relationship Between Ethnic Identity Development, Cognitive Complexity, Differentiation Of Self, And Reports Of Racial And Ethnic Microaggressions, Deshae C. Gatti

Electronic Theses and Dissertations

Although individuals may not engage in racism consciously due to social undesirability, they may have biases that manifest in more subtle and unconscious ways. Research has found that people of color experiencing different racial and ethnic microaggressions in their everyday lives are subject to pervasive and negative impacts on their mental health, though little is known about the influence of one’s ethnic identity formation, affective processes, and cognitive processes. A multiple regression analysis was conducted to examine the degree to which ethnic identity development, cognitive complexity, and differentiation of self were associated reported experiences of microaggressions. The analysis indicated that …

Searching For Color In Black & White: Epistemic Closure, The Rit Archives, And The Colonial Roots Of White Invisibility, Andrew James

Theses

When examining an image, a viewer often focuses on what they see and less often on what they are able to see. Nowhere is this as true, and as problematic, as it is with the visual representation of persons of African descent. This study describes how problematic photographic representation was used as a powerful semiotic tool in the Victorian age conquest of the other, was exported to early Hollywood (creating a lucrative hate-based industry), and was then pushed back into the cultural recesses, settling finally into systemic forms of modern oppression, empowered by the invisibility of whiteness. Images from the …

Towards Bio-Inspired Cementitious Materials: The Effect Of Organic Polymeric Materials On The Nanostructure And Nanomechanical Properties Of Calcium-Silicate-Hydrate, Mahsa Kamali

Open Access Dissertations

This study aims to obtain a fundamental understanding of the effect of polymeric materials with distinct functional groups on the nanostructure and nanomechanical response of calcium-silicate-hydrate (C-S-H). Nature has created biological materials with hierarchical microstructure and superior mechanical and functional properties. This is achieved in nature through certain biopolymers with specific structures and functionalities directing growth, microstructure and macroscopic performance of biological materials. C-S-H comprises the primary component of the cement hydration product and plays a fundamental role in determining the mechanical and long-term characteristics of cement-based materials. The different size and molecular structure of polymers, and the complex structure …

The Role Of Cochlin In The Trabecular Meshwork, Teresia Angelica Carreon

Open Access Dissertations

Glaucoma affects over 70 million people worldwide and can result in irreversible progressive vision loss if left untreated. Primary open angle glaucoma is the most common form of the disease. This disease is characterized by an uncontrolled increase in intraocular pressure (IOP) and this characteristic remains the only modifiable risk factor. The trabecular meshwork (TM) is a filter-like structure responsible for aqueous humor filtration into Schlemm’s canal (SC) and into the episcleral veins (EV). It is believed that obstruction in the TM leads to impeded aqueous humor outflow resulting in an increase in IOP. It has previously been demonstrated that …

Variation In Latin American Lgbt Rights, Jordan A. Strickler

Open Access Theses

This thesis explores the current cross-national variation in Latin American LGBT rights since the beginning of the pink tide. I create the Latin American LGBT Rights Index that empirically measures each nation’s LGBT rights policies and use the index to quantitatively examine several economic, cultural, and political variables’ effects on LGBT policy outcomes. This work includes a multivariate panel analysis and qualitative case studies of Argentina, Brazil, and Nicaragua to examine how the left shift has had divergent outcomes on LGBT right in Latin America. I conclude this work with recommendations for further research.

Description Of A New Genus Of Primitive Ants From Canadian Amber, With The Study Of Relationships Between Stem- And Crown-Group Ants (Hymenoptera: Formicidae), Leonid H. Borysenko

Insecta Mundi

A detailed study of the holotype of Sphecomyrma canadensis Wilson, 1985 (Hymenoptera: Formicidae) from Canadian amber has led to the conclusion that the specimen belongs to a new genus, here named Boltonimecia gen.n. Since the taxonomy of stem-group ants is not well understood, in order to find the taxonomic position of this genus, it is necessary to review the classification of stem-group ants in a study of their relation to crown-group ants. In the absence of data for traditional taxonomic approaches, a statistical study was done based on a morphometric analysis of antennae. Scape elongation is believed to play an …

Review Of Carelli, A., And M.L. Monné, 2015. Taxonomic Revision Of Phygopoda Thomson, 1864 And Pseudophygopoda Tavakilian & Peñaherrera-Leiva, 2007 (Insecta: Coleoptera: Cerambycidae: Cerambycinae), Robin O. S. Clarke

Insecta Mundi

The taxonomic history of the rhinotragine genera Phygopoda Thomson, 1864 and Pseudophygopoda Tavakilian and Peñaherrera-Leiva, 2007 (Coleoptera: Cerambycidae: Cerambycinae) are discussed, and evidence is presented to suggest that some recent taxonomic changes made by Carelli and Monné (2015) were unjustified. Consequently, Phygopoda nigritarsis Gounelle, 1911 is moved to the genus Neophygopoda Melzer, 1933, creating the new combination Neophygopoda nigritarsis, the genera Panamapoda Clarke, 2014 and Paraphygopoda Clarke, 2014 are revalidated, and the species Paraphygopoda viridimicans (Fisher, 1952) and Paraphygopoda nappae Clarke, 2014 are also revalidated.

The Role Of Interactions Of Long Non-Coding Rnas And Heterogeneous Nuclear Ribonucleoproteins In Regulating Cellular Functions, Xinghui Sun, Mohamed Sham Shihabudeen Haider Ali, Matthew Moran

Department of Biochemistry: Faculty Publications

Long non-coding RNAs (lncRNAs) are emerging as critical regulators of various biological processes and human diseases. The mechanisms of action involve their interactions with proteins, RNA and genomic DNA. Most lncRNAs display strong nuclear localization. Heterogeneous nuclear ribonucleoproteins (hnRNPs) are a large family of RNA-binding proteins that are important for multiple aspects of nucleic acid metabolism. hnRNPs are also predominantly expressed in the nucleus. This review discusses the interactions of lncRNAs and hnRNPs in regulating gene expression at transcriptional and post-transcriptional levels or by changing genomic structure, highlighting their involvements in glucose and lipid metabolism, immune response, DNA damage response, …
