Against the backdrop of calls for a more just form of capitalism, this paper specifically focuses on the notion of equality within capitalist societies and utilizes findings from a computer simulation to explore which of one two fundamental principles, namely: (1) equality of opportunity; or (2) equality of outcome might better inform and guide reform efforts to create more uniform distribution of wealth among members of society. In this study, Agent Based Modeling (ABM), as a form of computer simulation was used to explore how the fundamental principles of equality of opportunity or equality of outcome might impact wealth …


Considering Positive Psychology Constructs Of Life Satisfaction And School Connectedness When Assessing Symptoms Related To Attention-Deficit/Hyperactivity Disorder, Emily B. Mancil, Jason M. Bird, Mike Lyons, Kathryn Van Eck, Bradley H. Smith Jun 2013

Considering Positive Psychology Constructs Of Life Satisfaction And School Connectedness When Assessing Symptoms Related To Attention-Deficit/Hyperactivity Disorder, Emily B. Mancil, Jason M. Bird, Mike Lyons, Kathryn Van Eck, Bradley H. Smith

Journal of Human Sciences and Extension

Children and adolescents diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD) demonstrate significant difficulty with academic and behavioral functioning. This, in turn, can lead to lower educational attainment and vocational achievement, which has serious long-term consequences and costs to individuals and society (Barkley, 2002, 2006; Mannuzza, Klein, Bessler, Malloy, & LaPadula, 1993). Researchers from a positive psychology framework suggest that ADHD symptoms (i.e., inattention, hyperactivity/impulsivity) alone may not fully explain academic impairment (Diener, Scollon, & Lucas, 2004). From the standpoint of positive psychology, life satisfaction and school connectedness are important constructs that examine positive life functioning; however, they have been understudied, particularly in …

Pharmaceutical Sciences Faculty Publications

Gene transfer of a human cocaine hydrolase (hCocH) derived from butyrylcholinesterase (BChE) by 5 mutations (A199S/F227A/S287G/A328W/Y332G) has shown promise in animal studies for treatment of cocaine addiction. To predict the physiological fate and immunogenicity of this enzyme in humans, a comparable enzyme was created and tested in a conspecific host. Thus, similar mutations (A199S/S227A/S287G/A328W/Y332G) were introduced into mouse BChE to obtain a mouse CocH (mCocH). The cDNA was incorporated into viral vectors based on: a) serotype-5 helper-dependent adenovirus (hdAD) with ApoE promoter, and b) serotype-8 adeno-associated virus with CMV promoter (AAV-CMV) or multiple promoter and enhancer elements (AAV-VIP). Experiments on …

Smoking Mediates The Relationship Between Adverse Childhood Experiences And Chronic Obstructive Pulmonary Disease In The Brfss Data, Andrew Messersmith Jun 2013

Smoking Mediates The Relationship Between Adverse Childhood Experiences And Chronic Obstructive Pulmonary Disease In The Brfss Data, Andrew Messersmith

Master of Public Health Capstone Presentations

Associations between adverse childhood experiences (ACEs) and adult health outcomes are well grounded in the empirical literature; such studies generally find both direct and indirect effects of ACE on health outcomes such as liver disease, cancer, and heart disease. In this study, the association between ACEs and chronic obstructive pulmonary disease (COPD) was examined, and smoking was assessed as a partial mediator in the ACE-COPD relationship. Data were collected from five states in which an eight category ACE module was included in the 2011 Behavioral Risk Factor Surveillance System (BRFSS). Logistic regression models were developed to test the mediational hypothesis-that …

Dartmouth Scholarship

Background: Aberrant DNA methylation is a prominent feature of many cancers, and may be especially relevant in germ cell tumors (GCTs) due to the extensive epigenetic reprogramming that occurs in the germ line during normal development. Methods: We used the Illumina GoldenGate Cancer Methylation Panel to compare DNA methylation in the three main histologic subtypes of pediatric GCTs (germinoma, teratoma and yolk sac tumor (YST); N = 51) and used recursively partitioned mixture models (RPMM) to test associations between methylation pattern and tumor and demographic characteristics. We identified genes and pathways that were differentially methylated using generalized linear models and …

Astrocyte-Specific Overexpression Of Insulin-Like Growth Factor-1 Protects Hippocampal Neurons And Reduces Behavioral Deficits Following Traumatic Brain Injury In Mice, Sindhu K. Madathil, Shaun W. Carlson, Jennifer M. Brelsfoard, Ping Ye, A Joseph D'Ercole, Kathryn E. Saatman

Spinal Cord and Brain Injury Research Center Faculty Publications

Traumatic brain injury (TBI) survivors often suffer from long-lasting cognitive impairment that stems from hippocampal injury. Systemic administration of insulin-like growth factor-1 (IGF-1), a polypeptide growth factor known to play vital roles in neuronal survival, has been shown to attenuate posttraumatic cognitive and motor dysfunction. However, its neuroprotective effects in TBI have not been examined. To this end, moderate or severe contusion brain injury was induced in mice with conditional (postnatal) overexpression of IGF-1 using the controlled cortical impact (CCI) injury model. CCI brain injury produces robust reactive astrocytosis in regions of neuronal damage such as the hippocampus. We exploited …

Out-of-hospital emergency care is in an early stage of development in Armenia. While efforts are underway by the Ministry of Health (MOH) and other organizations to reform the emergency medical services (EMS) system, little data exists on the status of pediatric emergency care (PEC). To evaluate the knowledge and attitudes of out-of-hospital emergency physicians (EPs) in pediatric rapid assessment and resuscitation, and to identify areas of improvement to the pediatric EMS system and PEC education in the capital, Yerevan, a cross-sectional, anonymous, self-administered Knowledge and Attitudes survey regarding pediatric rapid assessment and resuscitation was distributed to all out-of-hospital EPs in …


The Relationship Between Romantic Relationship Initiation Processes Of Single Lds Emerging Adults And Change In Attachment Working Models With Implications For Practice, Matthew Lloyd Call Jun 2013

The Relationship Between Romantic Relationship Initiation Processes Of Single Lds Emerging Adults And Change In Attachment Working Models With Implications For Practice, Matthew Lloyd Call

Theses and Dissertations

Relationship initiation is an integral part of romantic relationship development and a key developmental task of emerging adulthood (Arnett, 2004). In addition, relationship initiation practices (such as dating) have the capacity to impact the fluctuating levels of attachment insecurity (whether anxiety or avoidance) that an individual experiences over the course of emerging adulthood (Mikulincer & Shaver, 2007). In the present study, I utilized latent growth curve modeling to examine whether certain dating variables (first dates, second or more dates, relationship breakups, dateless weeks) compiled over a 32 week dating history, as well as age and gender could predict change in …

Sanders-Brown Center on Aging Faculty Publications

Serine-threonine protein kinases are critical to CNS function, yet there is a dearth of highly selective, CNS-active kinase inhibitors for in vivo investigations. Further, prevailing assumptions raise concerns about whether single kinase inhibitors can show in vivo efficacy for CNS pathologies, and debates over viable approaches to the development of safe and efficacious kinase inhibitors are unsettled. It is critical, therefore, that these scientific challenges be addressed in order to test hypotheses about protein kinases in neuropathology progression and the potential for in vivo modulation of their catalytic activity. Identification of molecular targets whose in vivo modulation can attenuate synaptic …

The Emergency Department (ED) is a place where disaster preparedness, public health surveillance, and in many cases, ambulatory primary care is provided. The increase in ED visits, combined with expanded services, has led to overcrowding and significant strains on resources. The purpose of this study was to conduct a retrospective data analysis of emergency department utilization in the Thomas Jefferson University Hospital (TJUH) community benefit areas in North Philadelphia and to determine if patients were utilizing the ED for conditions which could have been treated in the outpatient setting. A comprehensive literature review was conducted. The review focused on studies …


Prefrontal Activity Links Nonoverlapping Events In Memory, Marieke R. Gilmartin, Hiroyuki Miyawaki, Fred J. Helmstetter, Kamran Diba Jun 2013

Prefrontal Activity Links Nonoverlapping Events In Memory, Marieke R. Gilmartin, Hiroyuki Miyawaki, Fred J. Helmstetter, Kamran Diba

Biomedical Sciences Faculty Research and Publications

The medial prefrontal cortex (mPFC) plays an important role in memory. By maintaining a working memory buffer, neurons in prelimbic (PL) mPFC may selectively contribute to learning associations between stimuli that are separated in time, as in trace fear conditioning (TFC). Until now, evidence for this bridging role was largely descriptive. Here we used optogenetics to silence neurons in the PL mPFC of rats during learning in TFC. Memory formation was prevented when mPFC was silenced specifically during the interval separating the cue and shock. Our results provide support for a working memory function for these cells and indicate that …

Novel Space Alters Theta And Gamma Synchrony Across The Longitudinal Axis Of The Hippocampus., Stephanie C. Penley, James R. Hinman, Lauren L. Long, Etan J. Markus, Monty A. Escabí, James J. Chrobak

Open Access Author Fund Awardees' Articles

Hippocampal theta (6–10 Hz) and gamma (25–50 Hz and 65–100 Hz) local field potentials (LFPs) reflect the dynamic synchronization evoked by inputs impinging upon hippocampal neurons. Novel experience is known to engage hippocampal physiology and promote successful encoding. Does novelty synchronize or desynchronize theta and/or gamma frequency inputs across the septotemporal (long) axis of the hippocampus (HPC)? The present study tested the hypothesis that a novel spatial environment would alter theta power and coherence across the long axis. We compared theta and gamma LFP signals at individual (power) and millimeter distant electrode pairs (coherence) within the dentate gyrus (DG) and …
