Portrayals and Perspectives: The Representation of Gulf States in American Political Cartoons from Early Relations to 2020
No full textThis dissertation explores the evolving portrayal of Gulf States in American political cartoons from the early twentieth century through 2020. Drawing on a dataset of 724 cartoons by 220 American cartoonists, the study analyzes how visual satire has shaped and reflected public understanding of the Arabian Gulf region. Grounded in stereotyping theory, the research identifies recurring themes such as oil wealth, violence, terrorism, backwardness, betrayal, and cultural otherness. Through decade-by-decade analysis, it traces how global events—from the Cold War and oil embargoes to the Gulf War, 9/11, and the Arab Spring—intensified or shifted visual narratives surrounding Gulf States. Cartoons were sourced from newspapers, magazines, anthologies, and digital archives, then categorized by theme and analyzed for symbolism, caricature, and political context. The study shows how American cartoonists often used exaggerated features and symbolic elements to reinforce Orientalist stereotypes and to comment on U.S. foreign policy, media narratives, and Western anxieties. Unlike broader studies that conflate the Gulf with the wider Arab or Muslim world, this dissertation focuses specifically on Gulf States to uncover targeted portrayals and region-specific messages. The findings reveal a persistent pattern of dehumanization, ridicule, and cultural reductionism across eight decades of American media. By documenting these visual patterns, the dissertation highlights the long-standing role of political cartoons in shaping collective perspectives and urges greater media literacy and responsible visual storytelling that challenges reductive representations and fosters intercultural understanding
Oxide ion conductivity, Resistive-switching and Ferroelectricity of Doped-HfO2
Full text linkYttria-stabilised hafnia, Hf1-xYxO2-x/2 (x=0.15, 0.30 and 0.45), ceramics were prepared by solid
state synthesis and characterised by ac impedance spectroscopy. Electrical conductivity of
x=0.15 is one order of magnitude higher than x=0.30 and 0.45. All compositions are foremost
oxide ion conductors but they contain a small p-type electronic conduction via increasing Y3+
concentration and pO2. YSH materials therefore are mixed conductors. P-type conductivity
is attributed to created holes that is believed to be located on under-bonded oxide ions.
A study on the effect of a small dc bias on YSH ceramics shows enhancement of their
conductivity, transforming into a resistive switching behaviour. This behaviour is novel for
any bulk ceramics other than Ca-doped BiFeO3. Switching of YSH depends on both oxygen
partial pressure, pO2, and temperature. At low applied voltage, the increase in the
conductivity is associated with p-type behaviour commenced at the positive
electrode/ceramic interface, but with further applied voltage, YSH underwent a transition
from p-type to n-type behaviour which is commenced at the negative electrode/ceramics
interface. With increasing applied voltage, the total conductivity enhanced sharply by 1.5-
2.5 orders of magnitude that is reversible with hysteresis under removal of the applied
voltage.
The ac impedance results of Hf1-xZrxO2 thin films demonstrate a single homogeneous
component attributed to the bulk layer. Resistance of all compositions decreased with
increasing pO2 (N2-Air-O2). This decrease in resistance is associated with p-type electronic
conduction. In p-type materials, a decrease in resistance is related to the increase in number
of holes that can probably be located on under-bonded oxygen or created during the
preparation of the thin films. The equivalent circuit of a resistor in parallel with a seriesconnected CPE-C element gave best fitting to HZO thin film samples. Results of fixed
frequency variable temperature sweeps of permittivity, er, of HZO show a sharp peak at 464-
474 °C with a maximum permittivity of ~ 11100. This result is the first report of a peak in the
permittivity of HZO thin films that is attributed to a transition from ferroelectric into
paraelectric behaviour at Tc
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
