Victim Participation At The International Criminal Court And The Extraordinary Chambers In The Courts Of Cambodia: A Feminist Project?, Susana Sacouto Jan 2012

Victim Participation At The International Criminal Court And The Extraordinary Chambers In The Courts Of Cambodia: A Feminist Project?, Susana Sacouto

Scholarly Articles in Law Reviews & Journals

INTRODUCTION: Over the last couple of decades, and particularly since 1998, incredible advances have been made in the effort to end impunity for sexual and gender-based violence committed in the context of war, mass violence, or repression. Before this, crimes committed exclusively or disproportionately against women and girls during conflict or periods of mass violence were either largely ignored, or at most, treated as secondary to other crimes. However, evidence of the large-scale and systematic use of rape in conflicts over the last two decades helped create unprecedented levels of awareness of sexual violence as a method of war and …

This phenomenological study is an investigation of the phenomenon of African American grandparents raising their grandchildren in Southeastern rural Georgia and the resources available to them. It looked at what it will take to start a faith-based or community-based support group for these Africa American grandparents raising their grandchildren in a rural setting. The concept of phenomenology served as the theoretical foundation for the study with social ecological model and social support …


Minority Stress And Physical Health In Lesbians, Gays, And Bisexuals: The Mediating Role Of Coping Self-Efficacy, Fowler Nicholas Denton Jan 2012

Minority Stress And Physical Health In Lesbians, Gays, And Bisexuals: The Mediating Role Of Coping Self-Efficacy, Fowler Nicholas Denton

Theses and Dissertations--Educational, School, and Counseling Psychology

Mental health issues have been the primary focus of much of the health research concerning lesbian, gay, and bisexual (LGB) individuals over the previous decade. Studies have demonstrated that LGB individuals experience psychological distress due to prejudice and discrimination (Lewis, Derlega, Berndt, Morris, & Rose, 2002; Meyer, Schwartz, & Frost, 2008; Rostosky, Riggle, Horne, & Miller, 2009). Health researchers have not given the physical health of LGB individuals the same level of attention (Dibble, Eliason, & Christiansen, 2007). The Gay and Lesbian Medical Association (GLMA; 2001) asserted that little was known about LGB physical health disparities and called for more …

Factors Influencing Women’S Psychological Well-Being Within A Positive Functioning Framework, Krista Moe

Theses and Dissertations--Educational, School, and Counseling Psychology

Women suffer a high prevalence rate of several mental disorders. National U.S. data (N = 9,282) shows that 23.4% of women meet the criteria for an anxiety disorder, 8.6% for depression, and 11.6% for a mood disorder (Kessler et al., 2005). Compared to men, women are two times more likely to be depressed (Lewinsohn, Rhode, Seeley, & Baldwin, 2001) and two to three times more likely to suffer from anxiety disorders such as panic disorders, phobias, obsessive compulsive disorders, and Posttraumatic Stress (Kessler et al., 2005). Due to experiencing a high number of mental disorders, women’s psychological well-being (PWB) …

Training Parent Volunteers As Effective Allies In Youth Empowerment Programs, Ria Shroff Jan 2012

Training Parent Volunteers As Effective Allies In Youth Empowerment Programs, Ria Shroff

Capstone Collection

Empowering adolescent girls is an effective and sustainable way to break the cycle of poverty and initiate a process of worldwide change. It is also extremely challenging, given the traditional perceptions of adolescents as reckless, carefree, incapable of assuming responsibility and unaware of their own needs for success and positive development. While organizations can provide many of the resources that adolescent girls need, the lack of parental support can be detrimental to both the overall development of the adolescent girl, her access to services, her mobility in society and the choices she will have in her future.

In order to …

Where Do Adaptive Shifts Occur During Invasion? A Multidisciplinary Approach To Unravelling Cold Adaptation In A Tropical Ant Species Invading The Mediterranean Area, Olivier Rey, Arnaud Estoup, Merav Vonshak, Anne Loiseau, Simon Blanchet, Luis Calcaterra, Lucila Chifflet, Jean-Pierre Rossi, Gael J. Kergoat, Julien Foucaud, Jérôme Orivel, Maurice Leponce, Ted Schultz, Benoit Facon

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Evolution may improve the invasiveness of populations, but it often remains unclear whether key adaptation events occur after introduction into the recipient habitat (i.e. post-introduction adaptation scenario), or before introduction within the native range (i.e. prior-adaptation scenario) or at a primary site of invasion (i.e. bridgehead scenario). We used a multidisciplinary approach to determine which of these three scenarios underlies the invasion of the tropical ant Wasmannia auropunctata in a Mediterranean region (i.e. Israel). Species distribution models (SDM), phylogeographical analyses at a broad geographical scale and laboratory experiments on appropriate native and invasive populations indicated that Israeli populations followed an …

Application Of Default Rules To Address Financial Conflicts Of Interest In Academic Medical Centers, Joanna K. Sax Jan 2012

Application Of Default Rules To Address Financial Conflicts Of Interest In Academic Medical Centers, Joanna K. Sax

Faculty Scholarship

A recent report issued from the Institute of Medicine contains an extensive analysis of financial conflicts of interest (FCOIs) in biomedical science. In brief, an FCOI exists when a profit-seeking motive either unduly influences or appears to influence an academic scientist’s primary obligations. The cornerstone of current policy to address FCOIs at academic medical centers (AMCs) is disclosure; however, disclosure does not appear to appropriately regulate, manage, or eliminate FCOIs.

Although the relationships between intramural scientists and industry and extramural scientists and industry may be structurally different, they both can lead to FCOIs that threaten scientific integrity. Overall, the NIH …

Find The Cost Of Freedom: The State Of Wrongful Conviction Compensation Statutes Across The Country And The Strange Legal Odyssey Of Timothy Atkins, Justin Brooks, Alexander Simpson Jan 2012

Find The Cost Of Freedom: The State Of Wrongful Conviction Compensation Statutes Across The Country And The Strange Legal Odyssey Of Timothy Atkins, Justin Brooks, Alexander Simpson

Faculty Scholarship

Tim Atkins was wrongfully convicted of a crime he did not commit and spent 23 years in prison. Although compensation statutes like California's have admirable goals, Tim Atkins's case fell through some substantial cracks that prompted the Authors to write this Article. As two of the many lawyers who have worked on Tim's case over the years, it has been an incredibly frustrating journey to see him denied compensation after all that has been done to prove his innocence. California's statute is flawed and is being misinterpreted, just as other compensation statutes are flawed and misinterpreted around the country. This …


The Role Of Ubiquitin Ligases In The Control Of Organ Specific Autoimmunity, Gerard F. Hoyne Jan 2012

The Role Of Ubiquitin Ligases In The Control Of Organ Specific Autoimmunity, Gerard F. Hoyne

Health Sciences Papers and Journal Articles

Diabetes mellitus is characterized by chronic hyperglycemia caused by a deficiency in insulin action, insulin secretion or both. Type 1 diabetes is classified as the destruction of beta cells leading to a deficiency in insulin production. Type1 diabetes accounts for 5-10% of patients with diabetes and most commonly is caused by the autoimmune destruction of the beta cells in the pancreas. The adaptive immune system is composed of antigen specific T and B lymphocytes which play a central role in protecting the human body from infectious pathogens but occasionally autoreactive T and B cells can escape immune tolerance, become activated …

Digital Microscopic Imaging Of Important Taxonomic Characters Of Philippine Hydraena (Hydraenopsis) Species, Hendrik Freitag

Biology Faculty Publications

Biodiversity surveys have revealed several new aquatic beetle species of minute size (0.9 mm to 1.8 mm body length). Following modern standards of morphological taxonomy, internal and external microstructures such as aedeagus, ovipositor, spermatheca, gonocoxite as well as the distribution pattern and shape of certain hair structures were used to illustrate the distinguishing characters of new species. As even the smallest diaphragm opening of light microscopes fails to retrieve images of sufficient depth of the field, light microscope images under ZEISS Primo Vert inverted microscope, equipped with ZEISS LD Plan-ACHROMAT 20X objective lens, and an OLYMPUS SZ 61 stereomicroscope, were …


Molecular Mechanisms Involved In Inflammatory Angiogenesis Induced By Monocyte Chemotactic Protein Induced Protein-1 (Mcpip1), Arpita Roy Jan 2012

Molecular Mechanisms Involved In Inflammatory Angiogenesis Induced By Monocyte Chemotactic Protein Induced Protein-1 (Mcpip1), Arpita Roy

Electronic Theses and Dissertations

Major diseases such as cardiovascular diseases, diabetes, obesity and tumor growth are known to involve inflammatory angiogenesis. MCP-induced protein 1 (MCPIP1) encoded by ZC3H12A gene, was reported to promote angiogenesis and is addressed in my dissertation as MCPIP. The mechanism/s involved in the angiogenic differentiation induced by MCPIP was however unknown. The aim of this study was to bridge this gap in our knowledge and delineate the molecular mechanisms and sequential processes involved in angiogenesis mediated via MCPIP. To determine if angiogenesis induced by inflammatory cytokines, TNF-, IL-1 and IL-8 is mediated via induction of MCPIP, knockdown of MCPIP by …

Infraded Surface Plasmon Polaritons On Semiconductor, Semimetal And Conducting Polymer, Monas Shahzad

Electronic Theses and Dissertations

Conductors with IR (infrared) plasma frequencies are potentially useful hosts of surface plasmon polaritons (SPPs) with subwavelength mode confinement for sensing applications. The underlying aim of this work is to identify such conductors that also have sharp SPP excitation resonances for biosensor applications at infrared (3-11 m) wavelengths, where biological analytes are strongly differentiated by their IR absorption spectra. In this work, various materials were investigated such as a heavily doped semiconductor, a semimetal, a conducting polymer and its composite. Heavily doped silicon was investigated by tuning its plasma frequency to the infrared region by heavily doping. The measured complex …


The Behavior Of Cerium Oxide Nanoparticles In Polymer Electrolyte Membranes In Ex-Situ And In-Situ Fuel Cell Durability Tests, Benjamin Pearman Jan 2012

The Behavior Of Cerium Oxide Nanoparticles In Polymer Electrolyte Membranes In Ex-Situ And In-Situ Fuel Cell Durability Tests, Benjamin Pearman

Electronic Theses and Dissertations

Fuel cells are known for their high efficiency and have the potential to become a major technology for producing clean energy, especially when the fuel, e.g. hydrogen, is produced from renewable energy sources such as wind or solar. Currently, the two main obstacles to wide-spread commercialization are their high cost and the short operational lifetime of certain components. Polymer electrolyte membrane (PEM) fuel cells have been a focus of attention in recent years, due to their use of hydrogen as a fuel, their comparatively low operating temperature and flexibility for use in both stationary and portable (automotive) applications. Perfluorosulfonic acid …
