The role of working memory in compulsive checking and OCD:a systematic classification of 58 experimental findings

Despite the large body of research regarding the role of memory in OCD, the results are described as mixed at best (Hermans et al., 2008). For example, inconsistent findings have been reported with respect to basic capacity, intact verbal, and generally affected visuospatial memory. We suggest that this is due to the traditional pursuit of OCD memory impairment as one of the general capacity and/or domain specificity (visuospatial vs. verbal). In contrast, we conclude from our experiments (i.e., Harkin & Kessler, 2009, 2011; Harkin, Rutherford, & Kessler, 2011) and recent literature (e.g., Greisberg & McKay, 2003) that OCD memory impairment is secondary to executive dysfunction, and more specifically we identify three common factors (EBL: Executive-functioning efficiency, Binding complexity, and memory Load) that we generalize to 58 experimental findings from 46 OCD memory studies. As a result we explain otherwise inconsistent research – e.g., intact vs. deficient verbal memory – that are difficult to reconcile within a capacity or domain specific perspective. We conclude by discussing the relationship between our account and others', which in most cases is complementary rather than contradictory.

Short and long memory in stock returns data

Long memory in log-range series:do structural breaks matter?

This paper examines whether the observed long memory behavior of log-range series is to some extent spurious and whether it can be explained by the presence of structural breaks. Utilizing stock market data we show that the characterization of log-range series as long memory processes can be a strong assumption. Moreover, we find that all examined series experience a large number of significant breaks. Once the breaks are accounted for, the volatility persistence is eliminated. Overall, the findings suggest that volatility can be adequately represented, at least in-sample, through a multiple breaks process and a short run component.

Aspects Allogenic Memory in the Gorgonian Coral Swiftia Exserta

Accelerated graft rejection can be used to determine immune memory in the gorgonian coral swiftia exserta. The extent ofthe persistence of immune memory will be determined in this experiment using replicate sets that are time elapsed from 1, 3, and 6 month. Although corals lack circulatory systems which can be a component of adaptive systemic immunity, this study will attempt to determine whether this gorgonian coral is capable of transmitting immune information throughout its colonial body. Results showed that at each of the time points; one, three, and six months the secondary response group and the primary response group were significantly different (at p=0.001) therefore, demonstrating long term immune memory. While the primary response group and the 3rd party specificity response group were similar, both were significantly different (at p=O. 001) from the secondary response group which shows the response to be specific, with memory applicable to the original antigen. Systemic immunity was not determined to be present for 15 em and one week after initial sensitization.

On Record: Soundscapes as Metaphor and Physical Manifestation of Memory in Early Holocaust Novels and Contemporary Criticism

This thesis compares two perspectives on the production of Holocaust memory: a novel that leads up to The Holocaust in Britain and one that reflects the hindsight perspective of a liberator in the Soviet Union. The novels are Virginia Woolf’s BETWEEN THE ACTS and Vasily Grossman’s LIFE AND FATE. The analysis offers a locus of analysis for the diasporic literary energy created by the catastrophe in the 20th and 21st centuries. The project offers a theorized standpoint on the role of literature on official historical archives. Proposing a method through which contemporary readers can engage the diasporic event of The Holocaust, the project adopts both the extended metaphor and literal expression of soundscapes. Soundscapes encompass the immaterial processes of memorialization and the literal sonic textures developed in Holocaust novels. The critical perspective incorporates contemporary notions of narratology, archival practices, and cultural manifestations of language into the notion of literary ethnomusicology.

The Impact of Marijuana Use on Memory in Patients with HIV/AIDS

The most robust neurocognitive effect of marijuana use is memory impairment. Memory deficits are also high among persons living with HIV/AIDS, and marijuana use among this population is disproportionately common. Yet research examining neurocognitive outcomes resulting from co-occurring marijuana and HIV is virtually non-existent. The primary aim of this case-controlled study was to identify patterns of neurocognitive impairment among HIV patients who used marijuana compared to HIV patients who did not use drugs by comparing the groups on domain T-scores. Participants included 32 current marijuana users and 37 non-drug users. A comprehensive battery assessed substance use and neurocognitive functioning. Among the full sample, marijuana users performed significantly worse on verbal memory tasks compared to non-drug users and significantly better on attention/working memory tasks. A secondary aim of this study was to test whether the effect of marijuana use on memory was moderated by HIV disease progression, but these models were not significant. This study also examined whether the effect of marijuana use was differentially affected by marijuana use characteristics, finding that earlier age of initiation was associated with worse memory performance. These findings have important clinical implications, particularly given increased legalization of this drug to manage HIV infection.

On the Threshold of Paradise and Present: Memory in Contemporary Cuban – American Literature

The exile leaving his or her homeland for new and unknown territory travels with much more than just luggage and the clothes on his or her back. He or she carries a weighty collection of memories. Available for the exile in times when the harmony of the past is far removed from the difficult circumstances present during the process of cultural assimilation, these memories present an opportunity for the exile to fashion for him or herself an identity that mimics the realities of life in the home left behind. In this creative endeavor, I seek to examine the powerful potential of memory as it is exercised by a collection of Cubans and Cuban-Americans in different corners of the United States. Analyzing Achy Obejas’ Memory Mambo, Cristina García’s Dreaming in Cuban, Ana Menéndez’s In Cuba I Was a German Shepherd, and Elías Miguel Muñoz’s Brand New Memory, I aim to trace the suggestive potential of memory as it is used by each of the characters in these works in an effort to reconcile their Cuban identities with the ones that are in the process of creation in the U.S. I will borrow from a collection of literature dealing with identity and exile, relevant graduate-level theses on Cuban-American literature, as well as theoretical perspectives on memory formation and nostalgia in order to trace the various ways in which memory is relied on in the process of cultural assimilation and emotional coping. Being presented in Miami, which hosts the largest concentration of Cuban immigrants, this thesis aims to present itself as a reflective tool for Cubans and Cuban-Americans who may find value in seeing their personal sentiments portrayed in literature, thus allowing for a potential reevaluation of identity. If the existing literature on my topic of analysis reveals anything, it is that the scope of my project is one that has not been inspected previously, thus making my analytical contribution a new one that will add a new interpretive set of lens through which readers of contemporary Cuban-American literature can examine the works.
