Filming the Stage: Reflections on the Historical and the Aesthetic Perspectives of an Essential Archive of the Future

Since the appearance and growth of cinema, a close but sometimes ambiguous relationship has been forged between the “Seventh Art” and the performing arts. Although cinema evolved quickly to become an art form in its own right, the stage and the productions produced for this space remain an object of attention for film directors. The relationship between the audio-visual sector and the presentational arts torments historians, creators and aestheticians alike. Experimented with and made use of by some, with varying degrees of success, fully rejected by others, the filming of the stage always raises many practical questions as well as theoretical reflections. The purpose of this article is to tackle questions and the search for possible answers which illuminate the eternal dialectical tensions between performing arts and recorded performing arts

A Study of Selected Factors to Identify Sixth Grade Students Gifted in Mathematics

The identification of children who are gifted is common in schools of the United States. High I.Q. and achievement scores are traditionally used. This study explored the adequacy of these variables in mathematics education. Based on the Renzulli model for giftedness, the study assessed problem solving ability, and task commitment. Only students identified as having above average general ability were selected as subjects. Eighty-seven sixth graders were selected from three Knox County, Tennessee, middle schools to form six groups. These groups were stratified as high (128 or above), mid upper(116-127), and average (95-115) I.Q. scores coupled with either a mathematics achievement score of at least the 96th percentile or one of the 50th through the 95th percentile. No subject was state certified gifted at the time of testing. Since I.Q. and achievement scores are used in Tennessee to certify gifted students, the study addressed the question of whether the performance of students in Group I (highest I.Q. and achievement range and eligible for gifted certification) was significantly different from that of other groups. No significant differences in student performance, p \u3c .05, were found between Group I and other groups having high achievement scores (III and V) except for task commitment in Group V. These three groups represented an I.Q. range from average to the highest possible scores. Group I differed significantly only from Group VI (average I.Q./average-mid upper achievement) in all measures. The conclusions of the study were: 1. A particular I.Q. range is inadequate as a criterion for identifying gifted students in mathematics. 2. A particular mathematics achievement range could serve as a factor in identification. 3. Students who are certified gifted by I.Q. and achievement scores in some other subject area are not necessarily gifted in mathematics. 4. Because some students who appear gifted in mathematics are being overlooked by traditional measures, tests similar to those of this study should be used in addition to other measures for the identification of students gifted in mathematics

ATTACKING NEURAL NETWORKS WITH HIGH ENTROPY INPUT SAMPLING

Deep learning is becoming a technology central to the safety and accuracy of many types of systems. Unfortunately, attackers can create adversarial examples that manipulate Deep Neural Networks (DNN) into making incorrect predictions by carefully crafting perturbations that, to humans, look indistinguishable from examples the DNN would classify correctly. Research shows that adversarial examples exist near the decision boundary. Decision-based attacks are designed to find adversarial examples by traversing the data manifold toward the decision boundary using iterative sampling without any knowledge of the model parameters or gradients. In this sense, decision-based attacks are very important, as they apply to many real-world attack scenarios. We propose a new decision-based attack, High Entropy Input Sampling (HEIS), that iteratively steps toward the decision boundary by using entropy over class predictions as a heuristic to find adversarial examples without any knowledge of the model gradients. Using HEIS, we were able to produce adversarial examples that reduced the accuracy of a CIFAR-10 DNN from 91% to 11% for epsilon=0.2 and reduced the accuracy of ResNet50, an ImageNet DNN, from 81% to 22% for epsilon=0.4. Furthermore, we discovered that the adversarial examples are highly transferable to other models, causing dramatic drops in accuracy among all models tested. Finally, we use HEIS to break three state-of-the-art neural network defenses.Lieutenant, United States NavyApproved for public release. Distribution is unlimited

Developing Best Practices in Digital Library Assessment: Year One Update

In the face of limited resources and increasing demand for online access to digital library content, we need to strategically focus our efforts and better understand users, impact, and associated costs. However, methods for assessment of digital libraries are not standardized. In an effort to address this crucial gap, the Digital Library Federation Assessment Interest Group has engaged the community over the past year in the development of best practices and guidelines. With this article, the authors provide an update on progress to date and solicit participation in an evolving effort to develop viable solutions.Librarie

Comparison of Monomethylhydrazine/Hydroxypropylcellulose and Hydrocarbon/Silica Gels

Experimental studies have been performed to investigate rheology and droplet burning with different types of gelled propellants. Monomethylhydrazine has been gelled with organic hydroxypropylcellulose. JP-8 and RP-1 hydrocarbon gels have been produced with inorganic fumed silica particles. Rheological characterization showed the differences in terms of viscosity and yield stress behavior due to different types of gelling agents. Herschel-Bulkley and Carreau-Yasuda models have been used to characterize the gels with inorganic and organic gelling agents, respectively. First experiments with the Monomethylhydrazine/hydroxypropylcellulose gels showed a typical swelling process during combustion with a flexible viscous droplet surface. Contrary to that, the hydrocarbon/silica gels burned while a rigid silica structure was built, which remained unburned. Burning drop measurements have been compared to the d^2-squared law

Those seeking power are among us: decentralisation, political transformation and traditional authorities in the Inner Niger Delta (Mali)

This thesis is an empirical study of the changes resulting from decentralisation and democratisation processes that Youwarou, a small rural town in the Inner Niger Delta in Mali, has experienced over the last decade. At the beginning of the nineties, Mali has undertaken the decentralization of the state, a huge administrative reform. Officially, it was presented as an ideal tool which would bring development and democratisation at the local level via the multiparty game and local elections. B..

A practical approach to multi-modeling views composition

The use of several view models to specify a complex system is a common practice to provide the most appropriate abstractions to model its diverse concerns. When several view models are used to specify a system, it is necessary to compose them to generate the application. When the view models are expressed in different Domain Specific Modeling Languages a problem arises because a heterogeneous composition is required. A possible approach to avoid a heterogeneous composition is to transform the diverse models into low-level models using a common low-level modeling language as target. Therefore, when all the view models are transformed in low-level models specified with a common language, it is possible to apply a ho- mogeneous composition to obtain the final application. However, it is necessary to identify the elements to compose in the low-level. In this paper, we present an auto- matic mechanism to identify which elements will be composed. This mechanism is based on defining correspondence relationships between the high-level view mod- els and automatically deriving new correspondence between the generated low-level models
