Structural Violence In The New Hampshire Family Court System: An Autoethnographic Exploration, Ann Marie Moynihan Jan 2018

Structural Violence In The New Hampshire Family Court System: An Autoethnographic Exploration, Ann Marie Moynihan

Department of Conflict Resolution Studies Theses and Dissertations

The family law system effectuates case outcomes affecting the lives of parents, children, and society through court orders imposing important life decisions upon divorcing or unmarried parents, children, and post divorce families. While some cases are resolved in alternative dispute resolution forums, others enter the courtroom and judicial decisions cause unintended consequences for millions of adults and children each year. This research details a parent’s suboptimal family law system experience caused by judicial decision-making, highlighting the need to examine the causes of unintended systemic outcomes. The purpose of this research is to raise awareness and provide justification for systemic reform …

A Few Good Men: Narratives Of Racial Discrimination Impacting Male African American/Black Officers In The United States Marine Corps, Peter D. Freeburn

Department of Conflict Resolution Studies Theses and Dissertations

In the United States of America (U.S.), institutional marginalization and racial discrimination remains an arguably difficult subject to understand, both conceptually and pragmatically. Regarding governmental sectors, U.S. Armed Forces are institutions where discrimination must be critically explored in an attempt to provide an understanding of the reality faced by those who actually serve. This study involved the examination into racism within a specific elite governmental sector that emphasizes a philosophy of a unified oneness of all its members. Using a phenomenological approach, the study delved into the actual impact of racism within the Marine Corps, on the lives of individual …


Pulmonary Alveolar Proteinosis- A Case Report, Renee M. Horner, Douglas S. Gardenhire, Ralph D. Zimmerman Jan 2018

Pulmonary Alveolar Proteinosis- A Case Report, Renee M. Horner, Douglas S. Gardenhire, Ralph D. Zimmerman

Internet Journal of Allied Health Sciences and Practice

ABSTRACT

Background: Pulmonary Alveolar Proteinosis (PAP) is a rare pulmonary disorder caused by a congregation of excessive lipoproteinaceous material in the alveolar spaces due to impaired surfactant metabolism. The congregation of the protein in the alveolar space leads to difficulty in breathing, impaired pulmonary immunity, and susceptibility to both opportunistic and acquired pulmonary infections. Although Pulmonary Alveolar Proteinosis is rare, there are potential treatments. Whole-lung lavage is the most widely accepted therapy and course of treatment. An additional form of therapy, GM-CSF stimulating therapy, uses recombinant deoxyribonucleic acid (DNA) technology to increase white cell production.

Purpose: The purpose …

Digressions: Literary & Art Journal

Nature is a funny thing. It surrounds us, comforts us, even terrifies us. It can simultaneously calm us, humble us, and easily overwhelm us. In appreciating and understanding nature, we inadvertently appreciate and understand ourselves. As the natural world around us varies so we are varied; our diversity as a species is reflected in our surroundings and when we take a moment to understand those, we soon understand each other. Mother Nature’s ability to grow, transform, revolt, rebuild and birth new life from decay reflects our own ability to do the same. In this 15th volume of Digressions you’ll find …


Oneself As Another: Hermeneutics And Personality Assessment, Marvin W. Acklin Jan 2018

Oneself As Another: Hermeneutics And Personality Assessment, Marvin W. Acklin

Archives of Assessment Psychology

The scientific and philosophical background of personality assessment is examined, including review of hermeneutic methods in the human sciences. Following a keyword search and psychological test usage survey, it was concluded that the nomothetic scientific orientation predominates in forensic psychology. A topic debated since the middle 19th century, the triumph of the nomothetic has implications for personality assessment models, interpretive methods, and description of human lives. This paper contextualizes personality assessment in 19th and 20th century hermeneutical philosophy, including the status of the nomothetic/idiographic divide. Hermeneutic philosophy--represented in the work of Schleiermacher, Dilthey, Heidegger, Bultmann, Gadamer, and Ricoeur--offers rich and …


Problematic Autoethnographic Research: Researcher’S Failure In Positioning, Ji Young Shim Jan 2018

Problematic Autoethnographic Research: Researcher’S Failure In Positioning, Ji Young Shim

The Qualitative Report

This article problematizes and discusses the “auto”ethnographical approach, which has recently become pervasive in research-oriented writings, to “tell the story of self and subject” in order to analyze wider cultural and social conditions. This method can be found in the remarkable array of a variety of disciplines in which scholars have explicitly and implicitly highlighted identity-related issues. One problem with this approach is its failure to recognize the ideological generalization in identifying the researcher’s position, with the risk of eventually becoming a neutral “truth through the researcher’s reality.” This paper focuses on the crisis between history and memory in contextualizing …

Complete Mitogenome Sequences Of Smooth Hammerhead Sharks, Sphyrna Zygaena, From The Eastern And Western Atlantic, Derek S. Guy, Cassandra L. Ruck, Jose V. Lopez, Mahmood S. Shivji

Biology Faculty Articles

We report the first mitogenome sequences of the circumglobally distributed, highly mobile, smooth hammerhead shark, Sphyrna zygaena, from the eastern and western Atlantic. Both genomes were 16,729 bp long with 13 protein-coding genes, two rRNAs, 22 tRNAs and a non-coding control region. The two Atlantic shark sequences differ from each other by 13 SNPs, and by 43 and 44 SNPs from the published mitogenome of an S. zygaena specimen from the eastern Pacific Ocean. The cross-Atlantic mitogenome sequences reported here provide a resource to assist with population genetics studies of this widely exploited species of conservation concern.


Reaction To Safety Equipment Technology In The Workplace And Implications: A Study Of The Firefighter’S Hood, Brian W. Ward Dec 2017

Reaction To Safety Equipment Technology In The Workplace And Implications: A Study Of The Firefighter’S Hood, Brian W. Ward

The Qualitative Report

In the 1990s the firefighter’s hood became a standard article of safety equipment worn by municipal firefighters, eliciting a negative reaction among many of these firefighters. I used data from interviews with 42 firefighters to explain why this reaction occurred. Data analysis revealed that negative reactions ultimately stemmed from the hood’s disruption of autonomy, repudiation of the complex mental and physical skill needed to perform tasks required of firefighters, and hindrance in negotiating the life-threatening environment created by a fire. These findings indicate that when introducing new safety equipment technology to emergency response workers, their reaction to this equipment, and …


Forecasting The Spread And Invasive Potential Of Apple Snails (Pomacea Spp.) In Florida, Stephanie A. Reilly Dec 2017

Forecasting The Spread And Invasive Potential Of Apple Snails (Pomacea Spp.) In Florida, Stephanie A. Reilly

HCNSO Student Theses and Dissertations

Forecasting the potential range of invasive species is a critical component for risk assessment, monitoring, and management. However, many of these invasive species are not yet at equilibrium which can be problematic for many modelling approaches. Using the climate matching method, MaxEnt, a series of species distribution models (SDMs) and risk analysis maps were created for select apple snail species in Florida: Pomacea canaliculata, P. diffusa, and P. maculata. Apple snails, freshwater gastropods in the family Ampullariidae, are native to South America and were introduced to the United States via the pet trade approximately 40 years ago. …


Nuclear Genome Size Diversity Of Marine Invertebrate Taxa Using Flow Cytometric Analysis, Kyle Roebuck Dec 2017

Nuclear Genome Size Diversity Of Marine Invertebrate Taxa Using Flow Cytometric Analysis, Kyle Roebuck

HCNSO Student Theses and Dissertations

Genomic analysis provides a substantial amount of information on evolutionary history, novel genes, transcriptomic expression and regulation in response to environmental stimuli, how efficiently organisms utilize their genome, and directional genome evolution. Genome size analysis serves as the first step in the sequencing process, because sequencing and annotation costs are directly correlated with genome size. Invertebrates represent the vast majority of faunal diversity on the planet, and, to a greater extent, the marine environment, although they are vastly understudied when compared to vertebrate genomes. Flow cytometry is a widely used, reliable, and accurate means of estimating genome sizes and has …

Analysis Of Diagnostic, Preventive, And Disease-Modifying Therapeutic Measures Of Alzheimer’S Disease, Ghazal Habib Havoutis Dec 2017

Analysis Of Diagnostic, Preventive, And Disease-Modifying Therapeutic Measures Of Alzheimer’S Disease, Ghazal Habib Havoutis

HCNSO Student Capstones

Alzheimer’s disease (AD) is the most common late-onset neurodegenerative disorder and cause of dementia, characterized by the formation of neurofibrillary tangles and senile plaque deposits. The heterogeneous nature of the disease (both genetically and environmentally) makes it difficult to prevent or cure. Without prevention, the prevalence of AD is expected to triple by 2050. However, because the diagnosis of AD is usually preceded by years of cognitive impairment, early detection may aid in reducing prevalence. Thus, there is a need for validated diagnostic measures for early and improved diagnosis and prevention. In this review, current and ongoing classifiers of early …

Is The State Of The Air-Sea Interface A Factor In Rapid Intensification And Rapid Decline Of Tropical Cyclones?, Alexander Soloviev, Roger Lukas, Mark A. Donelan, Brian K. Haus, Isaac Ginis Dec 2017

Is The State Of The Air-Sea Interface A Factor In Rapid Intensification And Rapid Decline Of Tropical Cyclones?, Alexander Soloviev, Roger Lukas, Mark A. Donelan, Brian K. Haus, Isaac Ginis

Marine & Environmental Sciences Faculty Articles

Tropical storm intensity prediction remains a challenge in tropical meteorology. Some tropical storms undergo dramatic rapid intensification and rapid decline. Hurricane researchers have considered particular ambient environmental conditions including the ocean thermal and salinity structure and internal vortex dynamics (e.g., eyewall replacement cycle, hot towers) as factors creating favorable conditions for rapid intensification. At this point, however, it is not exactly known to what extent the state of the sea surface controls tropical cyclone dynamics. Theoretical considerations, laboratory experiments, and numerical simulations suggest that the air-sea interface under tropical cyclones is subject to the Kelvin-Helmholtz type instability. Ejection of large …
