      Piszcz, Alan; Ishaq, Naseem; Advisor; Novillo, Jorge E; Reviewer; Sengupta, Saumendra; Reviewer (1993)
      Objected oriented languages and artificial neural networks are new areas of research and development. This thesis investigates the application of artificial neural networks using an object oriented C++ backpropagation simulator. The application domain investigated is hand printed text and engineering symbol recognition. An object oriented approach to the simulator allows other simulator paradigms to reuse a large body of the object classes developed for this particular application. The review and implementation of image feature extraction methodologies is another area researched in this paper. Four feature techniques are researched, developed, applied and tested, using digits, upper case alphabet characters and engineering symbol images. Final implementation and testing of the feature extraction methods with a baseline technique is analyzed for applicability in the domain of hand printed text and engineering symbols
    • Objective Assessment of Retinal Ganglion Cell Function in Glaucoma

      Joshi, Nabin (2017-09-25)
      Glaucoma refers to a group of diseases causing progressive degeneration of the retinal ganglion cells. It is a clinical diagnosis based on the evidence of structural damage of the optic nerve head with corresponding visual field loss. Structural damage is assessed by visualization of the optic nerve head (ONH) through various imaging and observational techniques, while the behavioral loss of sensitivity is assessed with an automated perimeter. However, given the subjective nature of visual field assessment in patients, visual function examination suffers from high variability as well as patient and operator- related biases. To overcome these drawbacks, past research has focused on the use of objective methods of quantifying retinal function in patients with glaucoma such as electroretinograms, visually evoked potentials, pupillometry etc. Electroretinograms are objective, non-invasive method of assessing retinal function, and careful manipulation of the visual input or stimulus can result in extraction of signals particular to select classes of the retinal cells, and photopic negative response (PhNR) is a component of ERG that reflects primarily the retinal ganglion cell function. On the other hand, pupillary response to light, measured objectively with a pupillometer, also indicates the functional state of the retina and the pupillary pathway. Hence, the study of both ERGs and pupillary response to light provide an objective avenue of research towards understanding the mechanisms of neurodegeneration in glaucoma, possibly affecting the clinical care of the patients in the long run.
    • Objective assessment of visual dysfunction in the acquired brain injury (ABI) population using the visual-evoked potential (VEP)

      Yadav, Naveen K. (2014-07-09)
      Purpose: To assess quantitatively and objectively selected visual dysfunctions in patients with mild traumatic brain injury (mTBI) (i.e., increased abnormal visual motion sensitivity (VMS), attentional deficits) and stroke (i.e., hemianopic visual field defects) by using empirically-derived, optimized pattern visual evoked potential (VEP) parameters derived from our laboratory. Furthermore, the goal was to develop simple and reliable clinical VEP protocols to assess the aforementioned visual dysfunctions in acquired brain injury. Methods: Four experiments were performed binocularly with full refractive correction using an objective, pattern VEP technique. Experiments #1-3 included both visually-normal (VN) adults and adults with mTBI, all ages 18-70 years. Experiment #4 included adult patients with stroke and hemianopic visual field defects, all ages 18-70 years. The following tests and stimulus conditions were used in Experiments #1-4: Experiment #1 – central field VEP with 10, 20, and 40 min arc check sizes at low (20%) and high (85%) contrast levels; Experiment #2 – central field VEP (baseline), binasal occlusion only (BNO), base-in prism (BI) only (4 pd total), and BNO with 4 pd BI; Experiment #3 – central field VEP (eyes open (EO), baseline), eyes-closed (EC, “relaxed”), and eyes-closed number counting (ECNC, “increased attentional state”); Experiment #4 – central field VEP, intact hemi-field only, and hemianopic field only. Results: The followings results were found: Experiment #1 – The 20 min arc check size provided the largest VEP amplitude and normative latency values at both contrast levels in both the VN and mTBI groups. These optimal parameters were then used to measure VEP responses in Experiments #2-4. Experiment #2 – With BNO alone, the VEP amplitude was larger in individuals with mTBI (90%) and smaller in the VN (100%) groups, as compared to other two test conditions and baseline. In addition, with BNO only, those with mTBI demonstrated improvement in their visual impressions and in performing specific sensorimotor tasks. Experiment #3 – Objectively-based alpha attenuation ratio (AR = EC ÷ EO, ECNC ÷ EC) was able to detect, assess, and differentiate between mTBI with versus without an attentional deficits, as well as between VNs. These objective AR findings were correlated with the subjective Adult ADHD Self-Report Scale (ASRS) questionnaire scores. Experiment #4 – The group and individual VEP findings showed that the central field and the intact hemi-field VEP amplitudes were larger than found in the hemianopic field. Moreover, these objective findings were correlated with the subjective clinical perimetric results. Conclusions: The optimized VEP parameters provided quantitative, rapid, reliable, and repeatable responsivity in all experiments. These findings demonstrated that the conventional pattern VEP could be beneficial for researchers in general, as well as clinicians to differentiate between mTBI versus the VN group with a high probability, and also between mTBI with versus without an attentional deficit. In addition, the VEP could be used clinically to detect and assess hemianopic visual field defects in patients with stroke. Based on these findings, the VEP has the potential to be used as an objective visual system biomarker for the diagnosis of mTBI/concussion, and also as an objective adjunct clinical tool to detect visual field defects in patients with stroke.
    • Oculomotor rehabilitation for reading dysfunction in mild traumatic brain injury

      Thiagarajan, Preethi (2013-06-04)
      Abstract: Aim Considering the extensive neural network of the oculomotor subsystems, global damage as a result of traumatic brain injury could compromise precise oculomotor control, thus causing reading dysfunction. The aim of the present thesis was to evaluate comprehensively the effect of oculomotor-based vision rehabilitation in symptomatic individuals with respect to nearwork and reading and having a mild traumatic brain injury (mTBI). A wide range of laboratory and clinical parameters related to reading involving vergence, accommodation, and version were tested. Methods Twelve subjects with documented mTBI and nearvision-related symptoms participated in the study. A cross-over, interventional experimental design was used involving true “oculomotor” training and “SHAM” training. Each training protocol was performed for 6 weeks, 2 sessions a week, 45 minutes of actual training per session. During each training session, all three oculomotor subsystems (vergence/accommodation/version) were trained for 15 minutes each in a randomized order. All laboratory and clinical parameters were measured before (baseline) and after true oculomotor (post-OMT) and SHAM (post-SHAM) training. In addition, nearvision-related symptoms were assessed using the Convergence Insufficiency Symptom Survey (CISS) scale. Lastly, subjective attention was measured using the Visual Search and Attention Test (VSAT). iv Results Following true oculomotor training, there was a marked improvement in various laboratory and clinical parameters assessed. Over 80% of the abnormal parameters found at baseline testing were found to significantly improve with training. Dynamics of vergence and accommodation, along with clinically assessed maximum amplitudes, improved markedly. Versional saccadic eye movements demonstrated improved rhythmicity and accuracy. These results together had a significant positive impact on overall reading ability. The improved reading-related oculomotor behavior was reflected in reduction of symptoms. In addition, subjective attention was found to also improve with true oculomotor training. In contrast, none of the aforementioned parameters changed with SHAM training. Conclusions Oculomotor-based vision rehabilitation had a strong positive effect on reading-related oculomotor control. This oculomotor learning effect is suggestive of intact neuroplasticity mechanisms in a compromised brain following TBI.
    • The p53-Zn2+ Energy Landscape and Metallochaperone Hypothesis

      Loh, Stewart; Blanden, Adam (2017)
      p53 is a tumor suppressor protein found mutated in essentially half of human cancers, and dysfunctional in nearly all human cancers. Each DNA-binding domain of the protein contains a critical tetrahedrally coordinated Zn2+. In this work, we present a quantitative thermodynamic model describing the energetics of the p53-Zn2+ interaction, as well as the mechanism of action of a new class of therapeutic compounds we call synthetic zinc metallochaperones (ZMC) that restore proper structure and function to many mutant p53s by delivering Zn2+ to the protein in the cell. We combine recombinant protein expression and in vitrobiophysical characterization with cell biology, molecular biology, medicinal chemistry, and live cell imaging to address these issues. Our model for both the mechanism of action of ZMCs and the p53-Zn2+interaction are broadly based on the Metallochaperone Hypothesis originally proposed by our group in 2010. We find that the core tenants of the Metallochaperone Hypothesis are accurate, and have expanded that model to quantitatively describe the link between p53-Zn2+ binding and protein stability noted for decades in the field. We find that at physiological temperature and Zn2+ concentrations, wild-type p53 has a folding energy of ~0 kcal mol-1, and as such is exquisitely sensitive to inactivation by mutation, and rapidly changes the fraction folded in response to changes in Zn2+ concentration. We demonstrate that ZMCs are ionophores, transport Zn2+ from the extracellular space into cells, and rescue mutant p53 by increasing the intracellular free Zn2+ concentration. This increase in Zn2+ stabilizes the mutant proteins via the same mechanism previously described for substrate stabilization of enzymes, and is only seen in a "Goldilocks Zone" of Zn2+ concentrations and ZMC Kds. This presents a fundamentally new way to interact with and reactivate mutant p53s, and raises questions about the potential for biological exploitation of this interaction for signaling or other functions.
    • A Parent's Interactive guide to the Social Network

      Wasecka, Joseph James (2013-05-01)
      This project hopes to determine what characteristics of an eBook will afford learning and be an effective tool for educating parents and their children on the responsible use of social networking sites. Two separate literature reviews of related studies are conducted. The first begins by examining findings from previous research on the use of social media by young children. The purpose of this review is to determine the focus and content of the eBook. Literature was collected in an electronic database by using the following key words: Cyber bullying, Web 2.0 tools, Internet Safety. The second review looks at the characteristics of an Ebook that affords learning. Literature was collected in an electronic database by using the following key words: Multimedia, Hypertext, Online Learning, Interactivity, E-books and education. E-book prototypes of an eBook were created using Flip Book Creator Professional. The Prototypes were designed using information from previous studies, Information Interactive Design and applying some of the Universal Principles of Design that afford learning. The hope is that the eBook will bridge the gap between what schools are doing and what parents need to do. The idea is that parents are going to stay connected with their children while they are online. The E-book will help educate and prepare parents to guide their children while using the “Social Network”.
    • Participant Interaction and Social Exchange-Centered Design in Massively Multiplayer Online Role-Playing Games: A Qualitative Study of Furcadia

      Scialdone, Michael J (2007-08-01)
      The purpose of this ethnography is to understand participant interaction in a Massively Multiplayer Online Role-Playing Game (MMORPGs). As participation and action of users are the glue of any community, it is imperative to examine how and why people congregate in graphical virtual environments. This relatively new phenomenon is studied within both existing and emerging schools of social thought. In this paper, the question is asked: how do participants interact within the context of an MMORPG, and are they encouraged to do so? This question is answered through an ethnographic study of one such MMORPG entitled Furcadia. This study applies both Human-Centered Design (to answer the how), and Social Exchange Theory (to answer the why). It is asserted that MMORPGs can be explained through a marrying of theories into a new one entitled Social Exchange-Centered Design.
    • Password Habits of Security Literate Individuals

      Mahesh, Namrata; Hash, Larry; Advisor; Marsh, John; Reviewer; White, Joshua; Reviewer (2018-05)
      In the age of the Internet, the common user has accounts on multiple websites. Basic account authentication has a username and a password. While username may be common knowledge, passwords are secret, and it is important to use good password habits. Security literate internet users, i.e, students, faculty, professionals in the IT industry are expected to know better than to use bad password habits. But that may not always be the case. This thesis aims to test the hypothesis that security literate internet users use bad password habits despite knowing better, and then proceeds to understand the underlying factors behind these habits through a survey. The survey consisted of questions about basic password habits. The responses were analyzed for better insights
    • Patterns of Psychopathology and Dysfunction in High-Risk Children of Parents With Panic Disorder and Major Depression

      Biederman, Joseph; Faraone, Stephen V.; Hirshfeld-Becker, Dina R.; Friedman, Deborah; Robin, Joanna A.; Rosenbaum, Jerrold F. (American Psychiatric Association Publishing, 2001-01)
      Objective: The purpose of the study was to evaluate 1) whether an underlying familial predisposition is shared by all anxiety disorders or whether specific risks are associated with specific disorders, and 2) whether panic disorder and major depression have a familial link. Method: The study compared four groups of children: 1) offspring of parents with panic disorder and comorbid major depression (N=179), 2) offspring of parents with panic disorder without comorbid major depression (N=29), 3) offspring of parents with major depression without comorbid panic disorder (N=59), and 4) offspring of parents with neither panic disorder nor major depression (N=113). Results: Parental panic disorder, regardless of comorbidity with major depression, was associated with an increased risk for panic disorder and agoraphobia in offspring. Parental major depression, regardless of comorbidity with panic disorder, was associated with increased risks for social phobia, major depression, disruptive behavior disorders, and poorer social functioning in offspring. Both parental panic disorder and parental major depression, individually or comorbidly, were associated with increased risk for separation anxiety disorder and multiple (two or more) anxiety disorders in offspring. Conclusions: These findings confirm and extend previous results documenting significant associations between the presence of panic disorder and major depression in parents and patterns of psychopathology and dysfunction in their offspring.
    • Pediatric mania: a developmental subtype of bipolar disorder?

      Biederman, Joseph; Mick, Eric; Faraone, Stephen V.; Spencer, Thomas; Wilens, Timothy E; Wozniak, Janet (Elsevier BV, 2000-09)
      Despite ongoing controversy, the view that pediatric mania is rare or nonexistent has been increasingly challenged not only by case reports, but also by systematic research. This research strongly suggests that pediatric mania may not be rare but that it may be difficult to diagnose. Since children with mania are likely to become adults with bipolar disorder, the recognition and characterization of childhood-onset mania may help identify a meaningful developmental subtype of bipolar disorder worthy of further investigation. The major difficulties that complicate the diagnosis of pediatric mania include: 1) its pattern of comorbidity may be unique by adult standards, especially its overlap with attention-deficit/hyperactivity disorder, aggression, and conduct disorder; 2) its overlap with substance use disorders; 3) its association with trauma and adversity; and 4) its response to treatment is atypical by adult standards.

    • People’s Perception of Smart Home Devices in their Homes & the Factors which Influence this Perception

      Thakur, Versha; Hash, Larry; Adviser; Marsh, John; Reviewer; Tekeoglu, Ali; Reviewer (2016-12-01)
      This thesis is to determine people’s perception of Smart home devices and the factors which influence this perception. Smart Home devices are becoming more common as many companies are launching various such devices. Although many companies are pushing these devices with extensive marketing, do people feel a need for these devices in their home? This thesis tries to find the answer to this question and what factors are affecting these opinions. Focus group methodology is used for this thesis. It is commonly used to perform qualitative researches. Based on the analysis of the Focus Group discussions, it is found that most people (from the targeted population) will be interested in adopting these smart home devices. There are some concerns which will still need to be addressed by the company such as security, Privacy and some health concerns to make the consumers more comfortable in adopting these devices.
    • PEP Tutorials: Using Cognitive Learning Theory in Creating Online Library Instruction

      Covino, Laura (2013-05-01)
      This paper describes the creation of online tutorials that teach about the PEP (Psychoanalytic Electronic Publishing) Archive, a full-text bibliographic database, for two small, graduate-level psychoanalytic institutes. ,QFUHDWLQJWKHWXWRULDOV WKHLQVWLWXWHV¶OLEUDULDQ used Camtasia Studio software and incorporated principles of cognitive learning theory. Research questions are, first, the practicality of creating and maintaining such online tutorials, and second, their effectiveness in providing PEP training. Methodology includes a literature review, pre-project survey, software choice and training, and preparation of recording scripts. The resulting tutorials do display features of cognitive learning theory, including learner control, encoding and individual differences, perception and attention, memory, and active learning. Conclusions are that for future projects, it would be best to create shorter tutorials along with additional, text-based training materials. The second research question is yet to be answered, and finding effective means of evaluation and assessment remains a challenge.

      Stam, Kathryn; Thesis Advisor; Jofre, Ana; Second Reader; Pierre, Marvin (2020-05)
      Approaching the end of my two-year journey through SUNY Poly’s online IDT program, I felt it was necessary for me to create an artifact showcasing my growth and progression as an Information Designer. Since I completed my degree entirely online (via distance learning), I decided to create a web portfolio representing my work in the program. This paper maps, from concept to execution, my process for creating a personal portfolio website. It includes research and analysis of existing portfolios websites, and it investigates how technology and selected design principles influence a website’s creation. The research presented here culminates with the creation and launch of my own personal portfolio website.
    • PHOSPHORYLATION AND UBIQUITINATION REGULATE PROTEIN PHOSPHATASE 5 ACTIVITY AND ITS PROSURVIVAL ROLE IN KIDNEY CANCER

      Mollapour, Mehdi; Dushukyan, Natela (2018)
      Protein Phosphatase 5 (PP5) is a serine/threonine phosphatase known to regulate many essential cellular functions including steroid hormone signaling, stress response, proliferation, apoptosis, and DNA repair. PP5 is a knownco-chaperone of the molecular chaperone heat shock protein 90 (Hsp90), and its regulation of Hsp90aidswiththe proper activation of Hsp90 clients and withsteroid hormone signaling.Hsp90 is also one of the strongest activators of PP5, as it releases the auto-inhibition of PP5 by interacting with the N-terminal tetratricopeptide repeat (TPR) domain of PP5. Our lab has recently shown that PP5 is phosphorylated at T362, and that this phosphorylation acts as an “on switch” resultingin the hyperactivation of PP5. Misregulation of this key phosphatase has been shown to aid in the tumor progression of ER-dependent and independent breast cancer. Elevated PP5 levels have also been linked to colorectalcancer, hepatocellular carcinoma (HCC), lymphoma, and prostate cancer. The work presented here reveals the pro-survival role that PP5 plays in kidney cancer. Clear cell renal cell carcinomas (ccRCC) are most often driven by mutations in the von Hippel-Lindau tumor suppressor (VHL). The data in this thesis shows that VHL binds and multi mono-ubiquitinates PP5 at two lysine residues K185 and K199. This post-translational modification negatively regulates PP5 likean “off switch” and ultimately leads to its degradation bythe proteasome. Mutations in the VHLgene that result in inactive mutants or a lack of VHL protein expression lead to ccRCC tumors. The data in this thesis shows that these VHL-nulltumors become dependent on elevated levels of PP5, and that both PP5 knockdown and inhibition lead to cancer cell death. The data further shows that the decrease in PP5 activity in VHL-null cells results in the induction of the extrinsic apoptotic pathway with a dramatic increase in the cleavage of PARP and caspases 3, 7, and 8.
    • Placebo and nocebo responses in randomised, controlled trials of medications for ADHD: a systematic review and meta-analysis

      Faraone, Stephen V.; Newcorn, Jeffrey H.; Cipriani, Andrea; Brandeis, Daniel; Kaiser, Anna; Hohmann, Sarah; Haege, Alexander; Cortese, Samuele (Springer Science and Business Media LLC, 2021-05-10)
      The nature and magnitude of placebo and nocebo responses to ADHD medications and the extent to which response to active medications and placebo are inter-correlated is unclear. To assess the magnitude of placebo and nocebo responses to ADHD and their association with active treatment response. We searched literature until June 26, 2019, for published/ unpublished double-blind, randomised placebo-controlled trials (RCTs) of ADHD medication. Authors were contacted for additional data. We assessed placebo effects on efficacy and nocebo effects on tolerability using random effects metaanalysis. We assessed the association of study design and patient features with placebo/nocebo response. We analysed 128 RCTs (10,578 children/adolescents and 9175 adults) and found significant and heterogenous placebo effects for all efficacy outcomes, with no publication bias. The placebo effect was greatest for clinician compared with other raters. We found nocebo effects on tolerability outcomes. Efficacy outcomes from most raters showed significant positive correlations between the baseline to endpoint placebo effects and the baseline to endpoint drug effects. Placebo and nocebo effects did not differ among drugs. Baseline severity and type of rating scale influenced the findings. Shared non-specific factors influence response to both placebo and active medication. Although ADHD medications are superior to placebo, and placebo treatment in clinical practice is not feasible, clinicians should attempt to incorporate factors associated with placebo effects into clinical care. Future studies should explore how such effects influence response to medication treatment. Upon publication, data will be available in Mendeley Data: PROSPERO (CRD42019130292).
    • Podcast Creation for In-Home Use: An Overview of Podcast Creation Methodology Using Bloom’s Taxonomy

      Stam, Kathryn; Thesis Advisor; Lizardi, Ryan; Second Reader; Holmes, William (2021-05)
      Making an effective podcast is more complex than just using your laptop mic to record your thoughts to post on your favorite social media, there are methods or approaches with which to achieve the best results. My project was to overview the methods for making effective audio podcasts and making them available professionally and accessibly to an audience using a subject matter revolving around 3D printing. The resulting example podcasts and the framework used to create them was examined using Bloom’s Taxonomy to assess the formation and delivery of the content for maximum information retention and engagement of the listener. The final goal of this research was to examine and identify the most important characteristics in meaningful audio development for creating podcasts that will properly deliver subject matter and engage the listener. I did an audio-only podcast using a standard Windows computer to create a short series of 15–20-minute podcasts to exemplify the points I discuss in this research. The hope for this research was to outline and display this discipline in a meaningful overview, I particularly planned to use Bloom’s Taxonomy to review this subject matter in how it can be used as a framework for making effective podcasts.
    • Podcast in a Box: A low cost and effective tool to produce compelling educational videos.

      Ward, James (2018-05)
      The current generation is the media generation, devoting more than a fifty percent or more of each day to media. As media devices become increasingly portable, and as it spreads even further through young our environment, from their schools to their cars, media messages will become an even more ubiquitous presence in an already media-saturated world. Turning our attention as educators to this fact requires harnessing the power of educational video for teaching and learning. Video has become an important part of education. It is integrated as part of traditional courses, serves as a cornerstone of many courses, and is often the main information delivery mechanism in MOOCs. Several meta-analyses have shown that technology can enhance learning , and multiple studies have shown that video, specifically, can be a highly effective educational tool. In order for video to serve as a productive part of a learning experience, however, it is important that the instructor has the correct tools for video design and implementation. This tool must be cost effective, easy to use, and be able to produce interesting, high quality video. My Podcast in a Box fills in this void.
    • Podcasting: The Process of Creating a Digital Narrative

      Cannarelli, Vincent; Schneider, Steven; Advisor; Stam, Kathryn; Reviewer (2016-12-01)
      Podcasts are an emerging and quickly growing form of information design to deliver some sort of message to a listener. The purpose of that message may be to teach, inform, discuss social happenings, narrate their life, talk to guests, tell stories, and so much more. Being able to speak to people in an organic, stream of conscious format, allows for a feeling of comfort and ease of listening. There’s many steps in order to create this digital narrative from starting a blog to host a podcast, recording and editing an episode, uploading to iTunes, and more. This paper is a complete overview of a digital media package including a website, blog, and podcast. You will learn the process of creating the site, recording a podcast, editing, music production, uploading to the site and then iTunes, Apple approval, and experiences had. Also there is an in depth view of motives of creating a podcast, influences, things learned.
    • POLITICAUSE.NET: DEVELOPING A VIRTUAL CROWDSOURCING COMMUNITY TO INCREASE THE ENGAGEMENT OF WOMEN IN POLITICS

      Stam, Kathryn; Thesis Advisor; Lizardi, Ryan; Second Reader; Topping, Veronique (2020-05)
      For the past 40 years, the continued growth and engagement of women in the political process has created opportunities to increase the influence of the female electorate. Through grassroots political activism, community networks, and online advocacy, women voters have been galvanized to come together collectively to take action to address relevant political issues, but this rising political enthusiasm has not translated into an equal focus on women's issues or equal representation in Congress. This thesis examines the factors that have contributed to the growth and influence of women's political advocacy and explores women's political engagement/activism, traditional vs. online activism, the effectiveness of all-women online networks, and female voter demographics. Based on this research, I developed a virtual crowdsourcing community as a shared space for members to propose and discuss important and timely women's issues including domestic violence, reproductive health, and pay equity and to collaborate to suggest relevant legislation to political leaders. The purpose of this social network is provide a platform for women activists and constituents to connect with others who want to advance the political causes that are relevant to women and to increase the engagement of women in politics to achieve gender equality in local and national government.
