    No full text
    Publication outputs and world shares of scientific publication are presented for 1981-2004 for China, Europe, India, Japan and the USA. Our results are compared with those available in the literature. The current situation whereby the main producers of scientific output statistics use different counting methods – thus, producing major differences in scientific output values – is unsatisfactory. The share in the total number of publications has been stagnating or gradually decreasing in recent years for Europe, the USA, India and Japan although there is no absolute decline in publication activities. The most dramatic trend has been the fast growth in China. The USA is still maintaining a lead in publication impact. The impact from EU, Japan, China and India increases but is still far behind that of USA

    “Art, Ritual, and Reform” is the first comprehensive study of the social history, devotional practices, and art patronage of the Arciconfraternita del SS. Crocifisso di San Marcello a Roma, one of the most prominent lay religious associations in sixteenth-century Italy. Divided into four main chapters, the dissertation first develops the innovative theory of conspicuous devotion through a documented examination of the company’s religious rituals and urban processions during the Catholic Reformation. The following chapters apply the theory to analyses of the confraternity’s commissions in the Cappella del Crocifisso in San Marcello and the nearby Oratorio del Crocifisso, in which Perino del Vaga (1501–47), Daniele da Volterra (1509–66), Giovanni de’ Vecchi (ca. 1536–1615), Cesare Nebbia (ca. 1536–1614), and Niccolò Circignani (ca. 1517/24–after 1596) painted. Challenging traditional interpretations of Central Italian painting from 1520 to 1590, the object-focused project argues that conspicuous meaning and form served conspicuous devotion to both instruct and inspire, in accordance with the reforms of the Catholic Church. A final chapter explores the archaism of paintings produced by Jacopino del Conte (1510–98) and Marcello Venusti (ca. 1512–79) for Santa Chiara a Monte Cavallo, a Capuchin convent founded by the confraternity on the Quirinal Hill. Reinforcing the assertions of the preceding chapters, the discussion demonstrates the company’s keen art historical, or stylistic, understanding, which enabled it to choose between different artistic modes to suit different subjects and contexts, as required by the Council of Trent (1545–63). Recovering both the variety and the devotional significance of lay festive performance and art patronage in sixteenth-century Rome, this crucial research offers a much needed critical reassessment of art, ritual, and reform in the Catholic Reformation.Ph.D.Includes bibliographical referencesby Kira Maye Albinsk

The certified thesis is available in the Institute Archives and Special Collections.Cataloged student-submitted from PDF version of thesis. "Submitted to the Department of Brian and Cognitive Sciences in supplement to the requirements for the degree of Bachelor of Science in Chemistry-Biology."Includes bibliographical references (pages 52-54).X-linked dystonia parkinsonism (XDP), also known as torsion dystonia type 3 (DYT3), afflicts hundreds of individuals. Under an X-linked mode of inheritance, the DYT3 haplotype occurs in Filipino populations and is of the highest frequency in the Panay Islands of the Philippines. Recently, convincing evidence has shown the causative mutation to be an insertion of the repetitive sequence SINE-VNTR-Alus (SVA). This insertion is associated with misregulation of 3' end exons in the gene TBP-associated factor 1 (TAF1). TAF1, the largest of fourteen TAF proteins, incorporates into a TATA binding complex that promotes transcription by RNA polymerase II. In a collaborative effort, singleplex BaseScope" probes as well as antibodies have been produced to target two TAF1 isoforms, canonical TAF1, C-TAF1, and neuronal TAF1, N-TAF1, separately. N-TAF1 differs from C-TAF1 by the inclusion of a two amino acid microexon, 3' to the SVA insertion, known as 34'. Here, I show that N-TAF1 expression is confined to neurons and interneurons whereas C-TAF1 is widely expressed, particularly by astrocytes, interneurons, neurons, and cells present in other organs including the heart and liver in mouse. Additionally, the antibodies produced show promise for use in human tissue. These results support the hypothesis that C-TAF1 and N-TAF1 have canonical and neuron-specific functions, respectively, and misregulation of N-TAF1 is capable of causing neuronal degeneration. Ultimately these results set the foundation for the study of C-TAF1 and N-TAF1 functions and isoform misregulation in XDP diseased tissue. Furthermore, these probes and antibodies may serve as tools for the validation of XDP models, under development, in which forthcoming XDP therapies may be tested.by Mercedes Maye Ondik.S.B. in Chemistry-Biolog

    Lotka' s Law, Co-authorship and Interdisciplinary Publishing

    No full text
    The robustness or breakdown of Lotka's law about the frequency distribution of scientific productivity depends on scientific cooperation, counting methods, interdisciplinary publishing and selection methods for sample collections. We have chosen to analyse the relationship using Mandelbrot's equivalent distribution model because this model is sensitive and uses the original data (scores). Five sets of authors and publications, the two sets used by Lotka, a set from High Energy Physics, a set from Microbiology and a set based on applicants to a research programme promoting young researchers have been used. It is shown that even for a sample of authors in High-Energy Physics with extremely strong co-authorship, Mandelbrot's distribution law is robust when complete-normalized (fractional) counting is used whereas complete counting results in a breakdown. In the field of Microbiology with much weaker cooperation, both counting methods result in a breakdown of Mandelbrot's law. Today a field like Microbiology with the corresponding set of journals, probably has a large content of interdisciplinary publishing and therefore no more fulfills the precondition of Lotka's law, that the total production of the authors (sources) is considered. For a set of applicants for the Emmy Noether Programme of the German Research Foundation. Mandelbrot's law breaks down despite the fact that all publications co-authored by the applicants are taken into account. In agreement with Bayes' theorem of conditional probabilities these results lead to the conjecture that any selection process of authors and/or publications causes a breakdown of Mandelbrot's law and, as a consequence Lotka's law

    A multidimensional evaluation of the relationship of tracking to student coursetaking opportunities within the English department at one urban high school

    No full text
    This research study investigated an English Department curricular system in an attempt to understand how the district tracking policies and procedures related to student coursetaking opportunities. Variables examined included student English achievement, postsecondary aspiration, and mobility or stratification.Five research questions guided this multidimensional research study. A qualitative methodology was used that combined historical analysis of school and department documents from 1970 to 1990 and interview protocol. This methodology permitted analysis of participants' perceptions of tracking, maintenance and use of tracking policies and procedures, coursetaking opportunities made available to students, and guidelines for course and track placement. A quantitative methodology was used to analyze 60 student transcripts from the classes of 1970 and 1990 samples, respectively, to determine English course achievement. A course hierarchy of grade level and track difficulty was developed to analyze student mobility or stratification by track beginning and end point."Two themes emerged reflecting the negative effect of tracking on regular track level students: district policy on weighted grades and inaccessibility of the honors track to regular track students. These themes were balanced by the school's addition of a regular tracked senior course, English 7-8 ""R,"" in 1990, and the encouragement of regular tracked students to take senior English. Policy-making implications on the use of a curricular tracking system included retaining the fourth year of English as a college preparatory course and reviewing the weighted grade policy for the lack of opportunity for mid-range students."Made available in DSpace on 2011-05-07T12:11:13Z (GMT).

    Beyond Nostalgia: Reinventing Home Within the Ruins of Exile in Arab Women’s Memoirs

    No full text
    This dissertation argues that contemporary exiled Arab American women memoirists—Leila Ahmed, Etel Adnan, and Mona Hajjar Halaby—turn life writing into a decolonial instrument, wielding the memoir as both refuge and rebellion. It contends that exile and nostalgia, often perceived as sites of loss, offer instead a generative vantage point from which to reconstruct selfhood. Moving beyond nostalgia as a paralyzing sentiment, this project critically interrogates nostalgia through a postcolonial and gendered lens—an insurgent practice that repurposes memory to dismantle imperial and patriarchal scripts. Through the close reading of three memoirs, the dissertation traces a trajectory of decolonial strategies. The first chapter examines Etel Adnan’s work as a poetics of metaphysical exile, where she inhabits a realm similar to Lacanian Imaginary to unbind herself from colonial constructs of home and language. The second chapter analyzes Leila Ahmed’s A Border Passage as an enactment of disruptive nostalgia—a method of excavating and reassembling cultural fragments to author a self beyond the colonial script of Arabness. The final chapter turns to Mona Hajjar Halaby, for whom return is not an endpoint but an ongoing intergenerational practice of (re)construction; sustained through the gendered diasporic labor of transforming her mother’s letters into a public counter-archive. Integrating frameworks from Edward Said, Franz Fanon, and other critical scholars, this project reveals the memoir as a critical technology of selfhood. These memoirists appropriate language itself—through catachresis, multilingualism, and archival curation—to refuse colonial interpellation and assert a right to self-narration. In doing so, they expose the memoir as both sanctuary and weapon: a site where exile’s fractures become fertile ground for creative reconstruction. Overall, this dissertation proposes a new taxonomy of resistance, positioning these works not merely as personal testimonies, but as decolonial blueprints that transform displacement into a continuous, generative act of (re)construction

    Improving throughput from ED to ICU/CCU

    No full text
    Background: Handoff report between the Emergency Department (ED) and the Intensive Care Unit/Critical Care Unit (ICU/CCU) is a time where patient information is shared and lost between the reporting and receiving nurses. Up to seventy percent of sentinel events happen as a result of communication errors, so it is imperative that information is reported accurately so that data is not lost in translation. In its 2006 National Patient Safety Goals, the Joint Commission called for a plan to standardize the way that handoff communication is delivered. Methods: This project explored the perception of handoff between the ED and ICU/CCU nurses by use of a Likert-style survey completed by the ICU/CCU nurses before and after an educational intervention for the ED nurses. After the initial surveys were collected from the ICU/CCU, ED nurses were assigned a PowerPoint style instruction on how to use the Illness Severity, Patient Summary, Action List, Situation Awareness, Synthesis (I-PASS) handoff tool. Outcomes: One month after the implementation was started, the nurses in the ICU/CCU were again surveyed to determine if there was a perceived improvement in how handoff communication was delivered. The number of results were limited due to the COVID-19 pandemic, but the data collected did not show a statistically significant difference in the staff perception of handoff. Implications: More data is needed to determine if this tool is effective in improving handoff. If the date proves the tool is ineffective, a modification or different tool should be used to improve handoff.DNPIncludes bibliographical reference
