A New Metric for Robustness with Respect to Virus Spread (Work in Progress)
No full textThe robustness of a network is depending on the type of attack we are considering. In this paper we focus on the spread of viruses on networks. It is common practice to use the epidemic threshold as a measure for robustness. Because the epidemic threshold is inversely proportional to the largest eigenvalue of the adjacency matrix, it seems easy to compare the robustness of two networks. We will show in this paper that the comparison of the robustness with respect to virus spread for two networks actually depends on the value of the effective spreading rate ?. For this reason we propose a new metric, the viral conductance, which takes into account the complete range of values ? can obtain. In this paper we determine the viral conductance of regular graphs, complete bipartite graphs and a number of realistic networks.Network Architectures and ServicesElectrical Engineering, Mathematics and Computer Scienc
A Statistical Comparison of the Apparent Importance of Various Prophets within Early Islamic and Christian Historical Documents
No full text Counts were made for the number of times prophets were mentioned in both the Qur'an and in the New Testament. Within the New Testament, the name Jesus (Isa) is cited far more than any other notable figure. Within the Qur'an, Moses is cited most often, followed by Abraham and Noah. Statistical analysis indicates that Jesus is cited between 4th and 11th most often among the prophets of Islam, which seemed surprising to the author, given that Jesus is considered to be the ultimate prophet by many Muslims. </jats:p
Arte de vanguardia, cine y modernidad: El siglo XX y un nuevo lenguaje
No full textEl presente ensayo considera que el cine fue el arte del siglo XX porque manifestó los principios básicos de la modernidad. Para llegar a ser una manifestación artística, el cine debió evolucionar como un lenguaje y realizar una ruptura con los principios tradicionales del arte, un diálogo y un desarrollo a partir del arte de vanguardia. El autor de este trabajo explora los orígenes del cine y la manera como se fue constituyendo en un lenguaje artístico.This essay considers that cinema was the art of the twentieth century because it manifested the basic principles of modernity. To become art, cinema had to evolve as a language and break with the traditional principles of art, a dialogue and a development based on avant-garde art. The author explores the origins of cinema and the way it was constituted as an artistic language

A content analysis of reading in textbooks for preservice teachers
No full textA content analysis of textbooks used in NCATE approved Florida teacher education programs for introductory courses in general reading (GR), reading remediation (RR), special education (SPED) and Teaching English to Speakers of Other Languages (TESOL) was conducted to determine the depth and breadth of reading theories, instructional components and assessments for word recognition presented to preservice teachers and whether the information presented is aligned with current research. To add depth to this study, a case study of the introductory textbooks used in one teacher education program was also conducted. A coding sheet was developed through a compilation of the research on word recognition and a pilot test. Individuals with advanced degrees in reading, special education, or TESOL coded the texts with each coder examining the textbooks in their area of expertise. Frequencies of the depth of presentation and author support were calculated. Results indicate that there is a discrepancy in the depth and support of word recognition theories, instructional components and assessments across disciplines. Case study results indicate that there is cohesiveness in the presentation of word recognition within a combination of textbooks used in one teacher education program and the program meets the International Reading Association competencies for preservice professional development in reading. It is suggested that if preservice teachers are going to learn how to best adapt instruction for exceptional students and English Language Learners, specific suggestions and research-based instructional practices need to be included in their textbooks or supplemental course materials. Further research of preservice texts' total word recognition content, including supplementary materials, is recommended.</p

Spectral graph analysis of modularity and assortativity
No full textExpressions and bounds for Newman’s modularity are presented. These results reveal conditions for or properties of the maximum modularity of a network. The influence of the spectrum of the modularity matrix on the maximum modularity is discussed. The second part of the paper investigates how the maximum modularity, the number of clusters, and the hop count of the shortest paths vary when the assortativity of the graph is changed via degree-preserving rewiring. Via simulations, we show that the maximum modularity increases, the number of clusters decreases, and the average hop count and the effective graph resistance increase with increasing assortativity.TelecommunicationsElectrical Engineering, Mathematics and Computer Scienc
The anthropological intrigue : conceptions, descriptions and narrations of Man in Hans Blumenberg’s Work
No full textL’œuvre de Hans Blumenberg, reçue d’abord pour son apport au débat sur la sécularisation et sa proposition d’une « métaphorologie », trouve son centre de gravité dans une anthropologie philosophique originale et complexe. C’est à celle-ci que notre thèse se consacre, en prenant acte du fait qu’« anthropologie » et « homme » sont les noms de deux problèmes avant d’être ceux d’un champ de savoir et de son objet. Si la pensée de Blumenberg s’élabore en premier lieu dans un dialogue critique avec la phénoménologie, ce n’est pas pour lui adjoindre le chapitre anthropologique qu’elle aurait omis, mais pour réformer de fond en comble ses thèses, sa méthode et ses principes implicites. Il ne s’agit pas non plus de retourner simplement aux questions et réponses traditionnelles que la philosophie a formulées à propos de l’homme. S’interrogeant, dans la lignée de l’anthropologie philosophique allemande, sur la possibilité de l’homme, Blumenberg oriente sa réflexion dans une voie « négative », dont notre travail s’attache à rendre raison autant qu’à interroger les limites. Avec l’image d’un homme fondamentalement « démuni », un être lacunaire, que les descriptions et narrations de l’auteur mettent en scène, ne retrouve-t-on pas une conception « prométhéenne », qui reconduit les présupposés qu’elle critiquait pourtant ? Notre interprétation vise, dans une analyse des procédures discursives que l’auteur met en œuvre et une discussion des thèses qu’il propose, à faire valoir leurs ambivalences, tout autant que leur fécondité. Ce qui est à lire, en dernière instance, dans l’œuvre de l’auteur, c’est un ensemble d’approches historiques et philosophiques de la « seconde nature » de l’homme, qui décrit les inquiétudes inhérentes à sa condition culturelle, autant que les intermittences du sujet.First appreciated for the contribution made to the ‘Secularisation’ debate, along with its conception of ‘Metaphorology’, the work of Hans Blumenberg represents a complex and original philosophical anthropology, the core reflections of which form the central focus of this dissertation. We begin from a point of questioning whether “anthropology” and “man” are not simply terms used to describe a field of academic practice and it’s topic of study, but rather two distinct issues to be examined. The dominant motive of Blumenberg’s thought is to be found in a critical dialogue with phenomenology, but he is not interested in simply contributing an anthropological ‘chapter’ to the field, rather he works to criticise and seek a total reform of the theses, methodology and implicit principles therein. He similarly refuses to rerun the familiar philosophical debates regarding man, instead questioning the possibility of man, inspired by the German philosophical tradition. This thesis will assess and critically consider this ‘negative’ turn in Blumenberg’s thought. Do his descriptions and narrative conveying the human as a fundamentally lacking being not tend to invoke a ‘promethean’ conception of man, the very assumptions of which they seek to criticise?Through analysis of Blumenberg’s discursive procedures and consideration of his theses, our interpretation intends to demonstrate their sense of ambivalence as well as their considered abundance. Ultimately, what is to be found in the work of this author is a collection of approaches to the ‘second nature’ of man which together describe the unease inherent in the cultural condition, as well as the intermittencies of the subject

THE LOCUS-OF-CONTROL ORIENTATIONS, ATTRIBUTION PATTERNS, AND ACHIEVEMENT LEVELS OF STUDENTS FROM FOUR COLLEGE BIOLOGY COURSES (GENDER DIFFERENCES)
No full textThis descriptive study examined relationships between student achievement, locus of control (LOC) orientation, and attributions for success and failure in biology. The study was conducted at a large, midwestern university with students from four college biology courses. Two of the courses had a traditional instructional format (\u27A\u27: developmental physiology; \u27B\u27: genetics) and two had a nontraditional format (audio-tutorial: introductory botany; inquiry: general biology). Students completed a demographic questionnaire and LOC and biology attribution scales during the first week of the semester. At the semester\u27s end, final grades and ability/aptitude measures were obtained. Using multiple correlations, analyses of variance, and step-wise regression equations, data were analyzed across and within courses. Locus of control orientation was the first personality factor assessed. In general, the population was skewed toward the internal side of the LOC scale. Specifically, students in the traditional courses were more internally oriented than those in the audio-tutorial and inquiry courses. Internally oriented students in the traditional \u27A\u27 course achieved higher final grades than did their more externally oriented peers. There were no other significant differences concerning LOC orientation. The other personality factor analyzed was causal attribution. Generally, students who attributed failure more to lack of ability achieved lower course grades. There also were significant differences in attributions of failure to lack of ability and effort among courses. The data were also analyzed for possible gender differences. Across courses, females attributed success more to effort than did males. There were no other significant gender differences. In the step-wise regression analysis across all courses, high school mathematics grade was found to be the best predictor of achievement in college biology. When courses were analyzed separately, grade in high school mathematics continued to be the best predictor in the inquiry and traditional \u27A\u27 courses. However, SAT mathematics score was the best predictor in the traditional \u27B\u27 course, while high school science grade was best in the audio-tutorial course. Ability/aptitude measures were the best predictors of achievement in college biology. However, LOC orientation and attribution of success and failure were found to interact with other factors affecting student achievement. (Abstract shortened with permission of author.
