Cholesterol-Cholate-Butterfat Diet Offers Multi-Organ Dysfunction In Rats, Humaira Jamshed, Jamshed Arslan, Anwar-Ul-Hassan Gilani Jan 2014

Cholesterol-Cholate-Butterfat Diet Offers Multi-Organ Dysfunction In Rats, Humaira Jamshed, Jamshed Arslan, Anwar-Ul-Hassan Gilani

Department of Biological & Biomedical Sciences

Background: Comparable to commercial expensive high-fat diets, cholesterol-cholate-butterfat (CCB) diet has also been used to induce hyperlipidemia in rats. Our objective was to explore its influence on multiple organs. Consequence of fasting was also analysed.
Methods: Rats in groups 1 and 2 received normal diet (ND) whereas groups 3 and 4 received CCB-diet. Food was withdrawn daily for two hours from groups 2 (ND-F) and 4 (CCB-F). Blood was collected at fourth and sixth week for biochemical estimation; Morris water maze was done in the sixth week for learning ability and memory; after which aortae were isolated for vascular reactivity. …


Remembering Vietnam: Offical History, Soldier's Memories And The Participant Interviewer, Ernest Benjamin Morris Jan 2014

Remembering Vietnam: Offical History, Soldier's Memories And The Participant Interviewer, Ernest Benjamin Morris

University of Wollongong Thesis Collection 1954-2016

This is a thesis that relies upon oral history to investigate the experiences of Australian soldiers serving in Vietnam in 1967. The thesis is unusual because the historian is the former platoon commander of these soldiers who recorded the narrations of former platoon members. The first half of the thesis examines the strengths and weaknesses of oral history and why the Vietnam War has produced so many controversial 'narrations' from veterans of the war. The second half of the thesis examines a controversy that affected this platoon and involved the killing of civilians in an ambush on 23 October 1967. …


Further Evidence Of The Comparative Memorability Of Alliterative Expressions In Second Language Learning, Frank Boers, Seth Lindstromberg, Stuart Webb Jan 2014

Further Evidence Of The Comparative Memorability Of Alliterative Expressions In Second Language Learning, Frank Boers, Seth Lindstromberg, Stuart Webb

Education Publications

Previous research has furnished evidence that alliterative expressions (e.g. a slippery slope) are comparatively memorable for second language learners, at least when these expressions are attended to as decontextualized items (Lindstromberg and Boers, 2008a; Boers et al., 2012). The present study investigates whether alliteration renders lexical phrases comparatively memorable also when these phrases are encountered in texts read primarily with a focus on content. Fifty-four EFL students read a text adapted so as to include five instances of 12 idiomatic expressions. The results of surprise post-tests suggest that the alliterative phrases among these target expressions left significantly stronger memory …


The Imagined After: Re-Positioning Social Memory Through Twentieth-Century Post-Apocalyptic Literature And Film, Amanda Ashleigh Wicks Jan 2014

The Imagined After: Re-Positioning Social Memory Through Twentieth-Century Post-Apocalyptic Literature And Film, Amanda Ashleigh Wicks

LSU Doctoral Dissertations

Maurice Halbwachs first proposed a collective approach to memory in the early twentieth century, but the vast majority of subsequent scholarship investigates memory’s social properties from a theoretical point of view. This project instead proposes that memory functions as a social phenomenon in significant and real ways, primarily understood through the social relations that arise within social frameworks, which provide a structure against which people’s memories come together to form important memory-narratives that configure individual and social consciousness. Once people transform memory from individual thought-image into socially structured language, memory takes on social properties. Memory relies upon social frameworks to …


"The Southern Heart Still Throbs": Caroline E. Janney And Partisan Memory‘S Grip On The Post-Civil War Nation, Heather L. Clancy '15 Jan 2014

"The Southern Heart Still Throbs": Caroline E. Janney And Partisan Memory‘S Grip On The Post-Civil War Nation, Heather L. Clancy '15

The Gettysburg College Journal of the Civil War Era

"Memory is not a passive act," writes Caroline E. Janney in the prologue of her 2013 book Remembering the Civil War: Reunion and the Limits of Reconciliation. Rather, it is a deliberate process. Our nation‘s history has been shaped by countless hands in innumerable ways, and the story of our civil war is no exception. In Remembering the Civil War, Janney seeks to turn our eyes once again onto the players, large and small, who shaped what came to be the accepted narrative of the conflict, from its inception through the 1930s and even bleeding through the Civil …


Fare Thee Well, Georgia L. Godwin Jan 2014

Fare Thee Well, Georgia L. Godwin

LSU Master's Theses

The common thread in all my work is time—its passage, effects, and remembrance. I have created a series of works that are meditations on time, the ephemeral quality of memory and the effects of aging, profession, and life decisions on our bodies, especially faces. The physical materials and my treatment of them reinforce these themes, showing the erosive qualities of earth, and drawing inspiration from natural features that signify the passage of time such as desert hoodoos, desert varnish, old wood, erosion and chemical oxidation, and from man-­‐made features such as old documents that have been written, erased, and rewritten. …


The Paradigm Of The Holocaust Will Not Last Forever, Richard A. Primus Jan 2014

The Paradigm Of The Holocaust Will Not Last Forever, Richard A. Primus

Book Chapters

In college I studied political theory. In class after class, I noticed that instructors and students alike regularly used the Holocaust as a way to test ideas. Any successful principle of political morality must show that the Nazis were wrong; any successful theory of political institutions must be structured to prevent Nazis from rising to power again. These were the implicit rules of the discipline. I preferred to argue in other ways. The Holocaust was personal, and too big to be put to use. Surely I could ground my ideas in something else, some problem or event other than the …


Stability And Accuracy Of Long-Term Memory For Musical Pitch [Journal Article], Alyce K. Hay, Craig P. Speelman Jan 2014

Stability And Accuracy Of Long-Term Memory For Musical Pitch [Journal Article], Alyce K. Hay, Craig P. Speelman

Research outputs 2014 to 2021

Existing research gives an inconsistent picture of the nature of the cognitive processes underlying memory for musical information. A study was conducted to investigate the stability and accuracy of long-term memory for pitch amongst individuals who have not had musical training. Excerpts from well-known pop songs were used as stimuli. Participants heard one long sequence of excerpts, each of which had been raised or lowered in pitch by one semitone, or left unaltered. After hearing each excerpt, participants were asked to detect whether it was different from the original version of the song they remembered. Participants were significantly worse at …


Simvastatin Reverses The Downregulation Of M1/4 Receptor Binding In 6-Hydroxydopamine-Induced Parkinsonian Rats: The Association With Improvements In Long-Term Memory, Qing Wang, Xiaobo Wei, H Gao, Jin Li, Jinchi Liao, X Liu, Bing Qin, Yinghua Yu, Chao Deng, B Tang, Xu-Feng Huang Jan 2014

Simvastatin Reverses The Downregulation Of M1/4 Receptor Binding In 6-Hydroxydopamine-Induced Parkinsonian Rats: The Association With Improvements In Long-Term Memory, Qing Wang, Xiaobo Wei, H Gao, Jin Li, Jinchi Liao, X Liu, Bing Qin, Yinghua Yu, Chao Deng, B Tang, Xu-Feng Huang

Faculty of Science, Medicine and Health - Papers: part A

Background It is believed that muscarinic M1/4 receptors are closely correlated to the dopaminergic system and are strongly involved in the pathogenesis of Parkinson's disease (PD). In addition to regulating lipid metabolism and protection from stroke, statins have been used to regulate the declined cognition. We aimed to explore the regional changes in M1/4 receptors in the 6-hydroxydopamine (6-OHDA)-lesioned rat brain. Methods PD rat model was set up by injecting 6-OHDA into the unilateral medial forebrain bundle; while simvastatin (10 mg/kg/day) or saline was orally administrated for 3 weeks, respectively. Long-term memory was measured using the Morris water maze. [3H]pirenzepine …


Visions And Revisions: Performance, Memory, Trauma, Sarah B. Miller Jan 2014

Visions And Revisions: Performance, Memory, Trauma, Sarah B. Miller

Faculty of Law, Humanities and the Arts - Papers (Archive)

Visions and Revisions is a collection of essays edited by Bryoni Trezise and Caroline Wake. Read individually, they are impressive and as a collection, quite compelling, but the subtext of all, and certainly the preoccupation of several, is human beings' ongoing cruelty to others. In seeking to explore the various ways in which we might enact, embody, perform, commemorate, intervene or take responsibility for terrible histories and current cruelties the effects and affects of which extend into our everyday, this collection also-to paraphrase Bryoni Trezise-reminds us of the potential for falling into a repertoire of behaviours, in order only to …


A New Perspective On Thinking, Memory And Learning In Gifted Adults With Asperger Syndrome: Five Phenomenological Case Studies, Nola Grace Norris Jan 2014

A New Perspective On Thinking, Memory And Learning In Gifted Adults With Asperger Syndrome: Five Phenomenological Case Studies, Nola Grace Norris

University of Wollongong Thesis Collection 1954-2016

In response to the call for first-hand accounts of individuals experiencing autism, this study addresses the need for qualitative investigation of the thinking and learning of gifted adults with Asperger syndrome (AS). The findings represent a broad phenomenological ‘map of the landscape’ of the experience of the participants and take the form of: (a) five case study reports; and, (b) a conceptual framework for understanding thinking and learning in autism, which was developed from the research literature. The need for such a framework is particularly relevant for professional development of teachers of students with AS in mainstream schools, however, the …


Temporal Determinants And Underlying Mechanisms Of The P300 Event-Related Potential Component, Genevieve Zara Steiner Jan 2014

Temporal Determinants And Underlying Mechanisms Of The P300 Event-Related Potential Component, Genevieve Zara Steiner

University of Wollongong Thesis Collection 1954-2016

A large portion of the event-related potential (ERP) oddball task literature, and associated theoretical development, has focused on context-related manipulations, and somewhat overlooked the temporal determinants of ERP components. The overarching aim of this doctoral thesis was to explore the mechanism underlying the systematic increases in amplitude, and decreases in latency, of the P300 ERP component that are observable when the interval separating presentations of matching stimuli is increased (target-to-target interval, TTI; nontarget-to-nontarget interval, NNI). This body of work suggests that the mechanism is operational on both target and (sometimes) nontarget events at specific processing stages. Support was evidenced for …


Living Memory And The Long Dead: The Ethics Of Laughing At The Middle Ages, Louise D'Arcens Jan 2014

Living Memory And The Long Dead: The Ethics Of Laughing At The Middle Ages, Louise D'Arcens

Faculty of Law, Humanities and the Arts - Papers (Archive)

Is there an ethics particular to laughing at the Middle Ages? What are the stakes of making the medieval past an object of postmedieval humour, and can the long dead of the Middle Ages laugh back at modernity?


A Little Goes A Long Way: Pressure For College Students To Succeed, Jennifer R. Davis Jan 2014

A Little Goes A Long Way: Pressure For College Students To Succeed, Jennifer R. Davis

The Journal of Undergraduate Research

When college students begin college they experience pressure from multiple sources. For example, they experience pressure from their parents to succeed, from their professors, and pressure from themselves to do well in classes. This pressure could lead to high anxiety and possibly even poor performance in classes. Prior research that has examined the impact of anxiety on performance includes the Yerkes-Dodson law and the Processing Efficiency Theory. Both argue that anxiety increases the performance to a point, but then performance decreases again with too much pressure. The Processing Efficiency Theory also includes motivation. This motivation increases the drive to succeed …


The Use Of Apps To Prime Learning For A Verbal Task, Christina Frederick, Devin Liskey, Daniel Brown Jan 2014

The Use Of Apps To Prime Learning For A Verbal Task, Christina Frederick, Devin Liskey, Daniel Brown

Publications

This study tested whether or not children’s memory performance would be affected by stimulating brain activity by completing a verbal puzzle task or a non-verbal puzzle task prior to a verbal learning task.


Echoes And Artifacts, Molly Elizabeth Miller Jan 2014

Echoes And Artifacts, Molly Elizabeth Miller

LSU Master's Theses

Architecture has many different contexts and meanings, but regardless of time and place, buildings act as a physical container of memory. This body of work explores the use of large facades as residue of a personal memory and uses physical deterioration to parallel the distortion of memory as a result of time and emotion. The work makes use of warping and tearing of materials and is created through the combination of large-scale relief prints, drawing, sewing, and the cutting away of materials. The exhibition includes an installation of fabric-based prints, a series of wall-based altered paper prints, and several artist …


Memory, Memorial, James Kimura-Green Jan 2014

Memory, Memorial, James Kimura-Green

LSU Master's Theses

My thesis exhibition investigates concepts of memory and memorial. These are fueled by feelings of yearning, longing, and nostalgia. We allow memories to linger. I believe we try to strengthen these memories, encase them and tuck them away deep in our minds. These memories create in our psyche psychological memorials. Like physical memorials, our memories too deteriorate and crumble over time. We fill in the gaps to the point where it is unknown just how true these memories are. At times I think that mine are now idealized and idyllic then they really were. The paintings in my exhibit are …


Rule-Based Category Learning In Children: The Role Of Age And Executive Functioning., Rahel Rabi, John Paul Minda Jan 2014

Rule-Based Category Learning In Children: The Role Of Age And Executive Functioning., Rahel Rabi, John Paul Minda

Brain and Mind Institute Researchers' Publications

Rule-based category learning was examined in 4-11 year-olds and adults. Participants were asked to learn a set of novel perceptual categories in a classification learning task. Categorization performance improved with age, with younger children showing the strongest rule-based deficit relative to older children and adults. Model-based analyses provided insight regarding the type of strategy being used to solve the categorization task, demonstrating that the use of the task appropriate strategy increased with age. When children and adults who identified the correct categorization rule were compared, the performance deficit was no longer evident. Executive functions were also measured. While both working …


Mediation Of Recurrent Hypoglycemia's Physiological And Behavioral Effects In The Hippocampus By Glucocorticoids, Danielle Osborne Jan 2014

Mediation Of Recurrent Hypoglycemia's Physiological And Behavioral Effects In The Hippocampus By Glucocorticoids, Danielle Osborne

Legacy Theses & Dissertations (2009 - 2024)

Recurrent hypoglycemia (RH) occurs with the over administration of insulin resulting in severe hypoglycemia on a repetitive basis. This occurs most commonly among Type I Diabetics who rely on exogenous insulin replacement for management of their disease; however it is becoming increasingly common among Type II Diabetics. Although cognitive deficits are reported during hypoglycemia, the period following restoration of euglycemia has been denoted by improved hippocampally-mediated short-term and working memory in humans and rodents, respectively. RH is also associated with an altered glucocorticoid secretion profile in response to hypoglycemia. In vitro and in vivo approaches were utilized with the goal …


The Role Of Relational And Item Specific Processing In The Survival Advantage Across English And Spanish, Crystal J. Robinson Jan 2014

The Role Of Relational And Item Specific Processing In The Survival Advantage Across English And Spanish, Crystal J. Robinson

Legacy Theses & Dissertations (2009 - 2024)

The current paper examines the effects of survival processing relative to item specific and relational processing on recall for both English monolinguals and Spanish-English bilinguals. It has been suggested that both item specific and relational processing play an important role in the survival advantage (Burns, Hart, Griffith, & Burns, 2012; Burns, Hwang, & Burns, 2011). However, to date, the generalizability of this advantage has yet to be examined cross-linguistically. In two studies, participants were asked to make survival relevance ratings, pleasantness ratings, and to categorize a set of words from either common taxonomic or ad hoc categories. Spanish-English bilinguals performed …


What You See Is What You Forget : Alcohol Cue Exposure, Affect, And The Misinformation Effect, Camille Crocken Barnes Jan 2014

What You See Is What You Forget : Alcohol Cue Exposure, Affect, And The Misinformation Effect, Camille Crocken Barnes

Legacy Theses & Dissertations (2009 - 2024)

Previous research has suggested that both alcohol cues and positive affect increase the tendency to incorporate false information into memory. This series of studies sought to determine if affect mediates the influence of alcohol cues on incorporation of false information into memory. Initially, a pilot study was completed to determine the individual differences that predict which individuals experience a heightening of positive affect following visualization exercises involving alcoholic beverages. Next, a study was conducted to determine if this affect increase from exposure to alcohol cues leads to increased acceptance of misinformation into memory. Participants' memories were tested while they were …


TodavíA Bailamos La Cueca Sola : From Local Protest Practice Against Chile's Dictatorship To (Trans)National Memory Icon, Karolina Sonja Babic Jan 2014

TodavíA Bailamos La Cueca Sola : From Local Protest Practice Against Chile's Dictatorship To (Trans)National Memory Icon, Karolina Sonja Babic

Legacy Theses & Dissertations (2009 - 2024)

This dissertation is a multi-sited cultural-historical ethnography about the cueca sola, a dance that was created to denounce the disappearances of citizens during Chile's dictatorship in the 1970s. Some women with missing relatives, who belonged to the music group Conjunto Folclórico of the Association of the Relatives of the Detained and Disappeared (AFDD), created a variation on the Chilean national dance (the cueca - traditionally a courtship dance between a man and a woman) which did not involve a male partner. Instead, they performed it alone. In so doing, these women, who were among the first to denounce the military's …


The Role Of Igf-Ii In Memory Enhancement : Implications For Autism Spectrum Disorders, Amy S. Kohtz Jan 2014

The Role Of Igf-Ii In Memory Enhancement : Implications For Autism Spectrum Disorders, Amy S. Kohtz

Legacy Theses & Dissertations (2009 - 2024)

Cognitive and memory impairments significantly affect multiple domains in life and play major roles in disease. Identifying critical mechanisms and factors that mediate memory consolidation and enhancement may represent an important approach for increasing cognition in normal adults and preventing or treating cognitive impairments. The expression of the C/EBP- target gene insulin-like growth factor 2, (IGF-II) is required for memory consolidation; furthermore, IGF-II administration during memory consolidation produces memory enhancement, increased memory persistence and prevents forgetting. In this thesis, I investigated the therapeutic potential of IGF-II to promote memory consolidation when administered systemically. In addition, I investigated one particularly interesting …

Effect Of Bdnf Val66met On Memory Decline And Hippocampal Atrophy In Prodromal Alzheimer's Disease: A Preliminary Study, Yen Y. Lim, Victor L. Villemagne, Simon M. Laws, David Ames, Robert H. Pietrzak, Kathryn A. Ellis, Karra Harrington, Pierrick Bourgeat, Ashley I. Bush, Ralph N. Martins, Colin L. Masters, Christopher C. Rowe, Paul Maruff

Research outputs 2014 to 2021

Objective: Cross-sectional genetic association studies have reported equivocal results on the relationship between the brain-derived neurotrophic factor (BDNF) Val66Met and risk of Alzheimer's disease (AD). As AD is a neurodegenerative disease, genetic influences may become clearer from prospective study. We aimed to determine whether BDNF Val66Met polymorphism influences changes in memory performance, hippocampal volume, and Aβ accumulation in adults with amnestic mild cognitive impairment (aMCI) and high Aβ. Methods: Thirty-four adults with aMCI were recruited from the Australian, Imaging, Biomarkers and Lifestyle (AIBL) Study. Participants underwent PiB-PET and structural MRI neuroimaging, neuropsychological assessments and BDNF genotyping at baseline, 18 month, …

President Obama charged the Presidential Commission for the Study of Bioethical Issues to identify a set of core ethical standards in the neuroscience domain, including the appropriate use of neuroscience in the criminal-justice system. The Commission, in turn, called for comments and recommendations. The MacArthur Foundation Research Network on Law and Neuroscience submitted a consensus statement, published here, containing 16 specific recommendations. These are organized within three main themes: 1) what steps should be taken to enhance the capacity of the criminal justice system to make sound decisions regarding the admissibility and weight of neuroscientific evidence?; 2) to what extent …


Learning To Pronounce First Words In Three Languages: An Investigation Of Caregiver And Infant Behavior Using A Computational Model Of An Infant., Ian S. Howard, Piers Messum Jan 2014

Learning To Pronounce First Words In Three Languages: An Investigation Of Caregiver And Infant Behavior Using A Computational Model Of An Infant., Ian S. Howard, Piers Messum

School of Engineering, Computing and Mathematics

Words are made up of speech sounds. Almost all accounts of child speech development assume that children learn the pronunciation of first language (L1) speech sounds by imitation, most claiming that the child performs some kind of auditory matching to the elements of ambient speech. However, there is evidence to support an alternative account and we investigate the non-imitative child behavior and well-attested caregiver behavior that this account posits using Elija, a computational model of an infant. Through unsupervised active learning, Elija began by discovering motor patterns, which produced sounds. In separate interaction experiments, native speakers of English, French and …


Changes In Cerebral White Matter, Vascular Risk And Cognition Across The Adult Lifespan, Andrew Robert Bender Jan 2014

Changes In Cerebral White Matter, Vascular Risk And Cognition Across The Adult Lifespan, Andrew Robert Bender

Wayne State University Dissertations

Numerous studies over the past decade have used diffusion tensor imaging (DTI) to examine associations between age, diffusion and anisotropy measures of cerebral white matter (WM), and cognitive performance. However, few have examined relationships between intra-individual change in DTI measures of WM and cognitive function. It is possible that the extant cross-sectional findings are a poor representation of age-related change in WM and cognition. The present study used latent difference-score modeling (LDM) to assess change over two years in DTI indices fractional anisotropy (FA), radial diffusivity (DR), axial diffusivity (DA) and mean diffusivity (MD). In addition, we examined the effects …

Counter-Narrating The Nation: Homi K. Bhabha's Theory Of Hybridity In Five Broken Cameras, Rachel Evers

Honors Projects

This paper examines the theories of Homi K. Bhabha, a major figure in contemporary post-colonial study. His work on hybridity, mimicry, and counter-narrative helps to illuminate the documentary film Five Broken Cameras, which shows five years in the life of Palestinian farmer, Emad Burnat, under Israeli occupation in the West Bank. The film is shown to be a performative counter-narrative representing Palestinian national becoming.


Detecting Knowledge Of Incidentally Acquired, Real-World Memories Using A P300-Based Concealed-Information Test, John B. Meixner Jr., J. Peter Rosenfeld Jan 2014

Detecting Knowledge Of Incidentally Acquired, Real-World Memories Using A P300-Based Concealed-Information Test, John B. Meixner Jr., J. Peter Rosenfeld

Scholarly Works

Autobiographical memory for events experienced during normal daily life has been studied at the group level, but no studies have yet examined the ability to detect recognition of incidentally acquired memories among individual subjects. We present the first such study here, which employed a concealed-information test in which subjects were shown words associated with activities they had experienced the previous day. Subjects wore a video-recording device for 4 hr on Day 1 and then returned to the laboratory on Day 2, where they were shown words relating to events recorded with the camera (probe items) and words of the same …

A Non-Erasable Magnetic Memory Based On The Magnetic Permeability, J R. Petrie, K A. Wieland, R A. Burke, G A. Newburgh, J E. Burnette, G A. Fisher, A S. Edelstein

United States Army: Publications

A non-erasable memory based on using differences in the magnetic permeability is demonstrated. The method can potentially store information indefinitely. Initially the high permeability bits were 10–50 μm wide lines of sputtered permalloy (Ni81Fe19) on a glass substrate. In a second writing technique a continuous film of amorphous, high permeability ferromagnetic Metglas (Fe78Si13Bg) was sputtered onto a similar glass substrate. Low permeability, crystalline 50 Jlm wide lines were then written in the film by laser heating. Both types of written media were read by applying an external probe field that is locally modified by the permeability …
