It is well known that young organisms do not maintain memories as long as adults, but the mechanisms for this ontogenetic difference are undetermined. Previous work has revealed that the α-amino-3-hydroxy-5-methyl-4isoxazolepropionic acidreceptor (AMPAr)subunits aretraffickedinto the synaptic membranefollowing memory retrieval in adults. Additionally, phosphorylated PSD-95-pS295 promotes AMPAr stabilization at the synapse. We investigated these plasticity related proteins as potential mediators in the differential contextual stress memory retrieval capabilities observed between adult and juvenile rats. Rats were assigned to either pedestal stress (1h) or no stress control (home cage). Each animal was placed alone in an open field for 5minat the base …
The Inter-Subject Correlation Of Eeg In Response To Naturalistic Stimuli, Samantha S. Cohen
The Inter-Subject Correlation Of Eeg In Response To Naturalistic Stimuli, Samantha S. Cohen
Dissertations, Theses, and Capstone Projects
Inter-subject correlation is a measure of the similarity of the brain activity of a group of people as they respond to the same naturalistic stimulus, typically a story or video, meant to simulate a real world experience. This thesis tests the hypothesis that the correlation of the brain responses of a group of people is indicative of stimulus engagement. The rationale is that the content of the stimulus drives brain activity in a consistent manner, while internal thoughts are divergent and result in uncorrelated activity. The inter-subject correlation (ISC) of neural responses have previously been assessed with fMRI, EEG, and …
Global Pretrial Detention Use: A Cross-National Analysis, Martin Schönteich
Global Pretrial Detention Use: A Cross-National Analysis, Martin Schönteich
Dissertations, Theses, and Capstone Projects
To better understand global pretrial detention patterns, this study explores economic, political, and social factors associated with two measures of pretrial detention: the number of pretrial detainees as a rate of the general population, and the number of pretrial detainees as a proportion of the overall prison population. Through simple correlation analysis, stepwise regression, and moderation analyses, the study identifies factors which are most strongly associated with the two pretrial detention measures. The literature does not report any large-scale cross-national studies on pretrial detention. This study addresses this gap, focusing exclusively on pretrial detention using a large cross-national sample of …
Perspectives On Natural Philosophy, Stanley N. Salthe
Perspectives On Natural Philosophy, Stanley N. Salthe
Publications and Research
This paper presents a viewpoint on natural philosophy focusing on the organization of substance, as well as its changes as invited by the Second Law of thermodynamics. Modes of change are pointed to as definitive of levels of organization; these include physical, chemical, and biological modes of change. Conceptual uses of the subsumptive hierarchy format are employed throughout this paper. Developmental change in dissipative structures is examined in some detail, generating an argument for the use of final causality in studies of natural systems. Considerations of ‘internalism’ in science are presented along the way.
Rates Of Developmental And Behavioral Screening Of Young Children: Implications For Health Care Policy And Practice, Shirley Berger
Rates Of Developmental And Behavioral Screening Of Young Children: Implications For Health Care Policy And Practice, Shirley Berger
Dissertations and Theses
Background: The skills and capacities developed during early childhood are the foundation for a child’s future academic functioning, economic productivity, and lifelong health and mental health. When young children have developmental delays or disabilities, early identification and intervention lead to better outcomes; however, only a minority are identified before school entry. Primary care is an important setting for identification of developmental and behavioral conditions as most young children attend well-child visits regularly and parents expect developmental guidance from pediatricians. Two key pediatric preventive services are recommended: developmental monitoring/surveillance at every well-child visit and developmental screening at 9 months, 18 months, …

Neural development is generally marked by an increase in the efficiency and diversity of neural processes. In a large sample (n=114) of human children and adults with ages ranging from 5 to 44 yr, we investigated the neural responses to naturalistic video stimuli. Videos from both real-life classroom settings and Hollywood feature films were used to probe different aspects of attention and engagement. For all stimuli, older ages were marked by more variable neural responses. Variability was assessed by the intersubject correlation of evoked electroencephalographic responses. Young males also had less-variable responses than young females. These results were replicated in …
