Confidence Intervals for Assessing Sizes of Social Network Centralities  [PDF]
Dawn Iacobucci, Rebecca McBride, Deidre L. Popovich, Maria Rouziou
Social Networking (SN) , 2018, DOI: 10.4236/sn.2018.74017
Abstract:
This research uses random networks as benchmarks for inferential tests of network structures. Specifically, we develop formulas for expected values and confidence intervals for four frequently employed social network centrality indices. The first study begins with analyses of stylized networks, which are then perturbed with increasing levels of random noise. When the indices achieve their values for fully random networks, the indices reveal systematic relationships that generalize across network forms. The second study then delves into the relationships between numbers of actors in a network and the density of a network for each of the centrality indices. In doing so, expected values are easily calculated, which in turn enable chi-square tests of network structure. Furthermore, confidence intervals are developed to facilitate a network analyst’s understanding as to which patterns in the data are merely random, versus which are structurally significantly distinct.
Un nome per il copista del più antico frammento della Divina Commedia: Andrea Lancia
Renzo Iacobucci
Scrineum Rivista , 2010,
Abstract: The ff. 127-128 of the manuscript Conventi Soppressi H. 8. 1012, preserved at the Biblioteca Nazionale Centrale of Firenze, contain a fragment of the Dante’s Inferno. This study aims at attributing this script to Andrea Lancia’s hand, notary, translator of classics, scribe and annotator of the Divine Comedy, through a comparison with the documents and the books written by the same Lancia. In particular, the script of the fragment shows a perceptible similarity with that of the documents produced between 1314 and 1315 and the handwriting of the ms. C. III. 25 of the Biblioteca Comunale degli Intronati of Siena, datable within 1320. Therefore, this datum really opens the way to an hypothesis whereby the fragment could be written while Dante was still alive, as Teresa De Robertis carefully presumed.
Structure Functions and Large Q^2 Cross Sections at HERA
Giuseppe Iacobucci
Physics , 2000,
Abstract: The data collected with the H1 and ZEUS detectors during the running period 1994-99 are used to give an experimental review on the proton structure functions and the neutral current and charged current large Q^2 cross sections in e^\pm p scattering at HERA.
Diffractive phenomena
Giuseppe Iacobucci
Physics , 2001, DOI: 10.1142/S0217751X02012697
Abstract: The most recent theoretical and experimental results in the field of diffractive scattering are reviewed. A parallel between the two current theoretical approaches to diffraction, the DIS picture in the Breit frame and the dipole picture in the target frame, is given, accompanied by a description of the models to which the data are compared. A recent calculation of the rescattering corrections, which hints at the universality of the diffractive parton distribution functions, is presented. The concept of generalized parton distributions is discussed together with the first measurement of the processes which might give access to them. Particular emphasis is given to the HERA data, to motivate why hard diffraction in deep inelastic scattering is viewed as an unrivalled instrument to shed light on the still obscure aspects of hadronic interactions.
Classroom Assessment Techniques: An Assessment and Student Evaluation Method  [PDF]
Dawn-Marie Walker
Creative Education (CE) , 2012, DOI: 10.4236/ce.2012.326136
Abstract: Some of the challenges that face Higher Education are how to ensure that assessment is meaningful and that feedback is prompt in order to promote learning. Another issue is how to provide lecturers with feedback regarding their efficacy, in a timely and non-judgmental manner. This paper proposes that Classroom Assessment Techniques (Angelo and Cross, 1993), maybe a good way of answering both of those issues. They are quick and easy tasks set within the lecture, which tests the student’s knowledge, providing an immediate opportunity for further elaboration if needed by the lecturer, therefore providing immediate feedback to the students. It also ensures that the lecturer has delivered the most salient messages, therefore also providing feedback to the lecturer.

Nutrient Use Efficiency of Three Fast Growing Hardwood Species across a Resource Gradient  [PDF]
Dawn E. Henderson, Shibu Jose
Open Journal of Forestry (OJF) , 2012, DOI: 10.4236/ojf.2012.24023
Abstract: Attitudes regarding traditional energy sources have shifted toward renewable resources. Specifically, short-rotation woody crop supply systems have become more prevalent for biomass and biofuel production. However, a number of factors such as environmental and inherent resource availability can limit tree production. Given the intensified demand for wood biomass production, forest and plantation management practices are focusing on increasing productivity. Fertilizer application, while generally one of the least expensive silvicultural tools, can become costly if application rates exceed nutrient uptake or demand of the trees especially if it does not result in additional biomass production. We investigated the effect of water and varying levels of nitrogen application (56, 112, and 224 kg·N·ha-1·yr-1) on nutrient content, resorption efficiency and proficiency, N:P and the relationship with ANPP, as well as leaf- and canopy-level nutrient use efficiency of nitrogen, phosphorus, and potassium for Populus deltoides, Quercus pagoda, and Platanus occidentalis. P. deltoides and P. occidentalis reached their maximum nitrogen budget with the application of water suggesting old agricultural fields may have sufficient nutrient levels to sustain short-rotation woody crops negating the application of additional nitrogen for these two species. Additionally, for P. deltoides and Q. pagoda application of nitrogen appeared to increase the uptake of phosphorus however, resorption efficiency for these two species were more similar to studies conducted on nutrient poor sites. Nutrient resorption proficiency for all three nutrients and all three species were at levels below the highest rates of nitrogen application. These findings suggest maximum biomass production may not necessarily be tied to maximum nutrient application.
The future of multimodal corpora
Knight, Dawn;
Revista Brasileira de Linguística Aplicada , 2011, DOI: 10.1590/S1984-63982011000200006
Abstract: this paper takes stock of the current state-of-the-art in multimodal corpus linguistics, and proposes some projections of future developments in this field. it provides a critical overview of key multimodal corpora that have been constructed over the past decade and presents a wish-list of future technological and methodological advancements that may help to increase the availability, utility and functionality of such corpora for linguistic research.
Moving to the Rhythm of Africa: a Case Study of a Tertiary Educator’s Understanding of Multicultural Dance in Teacher Education
Dawn Joseph
Journal of Education and Training Studies , 2013, DOI: 10.11114/jets.v1i1.82
Abstract: Australia is proud of its rich and varied array of the Arts depicting a range of cultural diversity formed by ongoing migration. Although the complex issues of dance, culture and identity are interconnected, forming a multicultural society in Australia, dance education is a powerful platform to transmit and promote togetherness where understanding and respect is shared in dance practice. The focus of this article is on dance education as part of multicultural arts education within teacher education courses at Deakin University (Melbourne) Australia. It forms part of my ongoing wider study that started in 2010 regarding Attitudes and perceptions of Arts Education Students: Preparing culturally responsive teachers across two continents (Australia and South Africa). In 2011, I interviewed the dance educator and will report on two themes from her interview data: multicultural dance and the inclusion of African dance within multicultural dance practice. I argue that the inclusion of innovative and immersive practice of dance where authentic teaching and learning can be facilitated is a powerful platform to share multicultural dance practice in tertiary education.
Emerging Open Source Health Information Business Ecosystems in Resource-Poor Environments: the OpenMRS Experience
