Creativity in the Brazilian Culture
Research has pointed out creativity as a sociocultural and contextually embedded phenomenon. As a consequence, the effect of cultural factors on the manifestation of creativity has been discussed worldwide. The purpose of this chapter is, therefore, to analyze the development of creativity in the Brazilian culture. A brief description of the Brazilian culture is provided. Models of creativity developed by Brazilian researchers, as well as a review of creativity studies conducted in the educational environment, are presented. Guidelines for future cross-cultural studies on creativity are also suggested

Listening comprehension and strategy use: a longitudinal exploration
This paper examines the development of strategy use over 6 months in two lower-intermediate learners of L2 French in secondary schools in England. These learners were selected from a larger sample on the basis of their scores on a recall protocol completed after listening to short passages at two time points: one was consistently a high scorer; the other one, a low scorer. Qualitative data on these two learners’ strategic behaviour were gathered at the two time points from verbal reports made by learners while they were completing a multiple-choice listening task. Our results show a high degree of stability of strategy use over the time period, with pre-existing differences between the high and low scorer persisting. The theoretical and pedagogical implications of these findings are discussed

Artificial neural network implementation of a near-ideal error prediction controller
A theory has been developed at the University of Virginia which explains the effects of including an ideal predictor in the forward loop of a linear error-sampled system. It has been shown that the presence of this ideal predictor tends to stabilize the class of systems considered. A prediction controller is merely a system which anticipates a signal or part of a signal before it actually occurs. It is understood that an exact prediction controller is physically unrealizable. However, in systems where the input tends to be repetitive or limited, (i.e., not random) near ideal prediction is possible. In order for the controller to act as a stability compensator, the predictor must be designed in a way that allows it to learn the expected error response of the system. In this way, an unstable system will become stable by including the predicted error in the system transfer function. Previous and current prediction controller include pattern recognition developments and fast-time simulation which are applicable to the analysis of linear sampled data type systems. The use of pattern recognition techniques, along with a template matching scheme, has been proposed as one realizable type of near-ideal prediction. Since many, if not most, systems are repeatedly subjected to similar inputs, it was proposed that an adaptive mechanism be used to 'learn' the correct predicted error response. Once the system has learned the response of all the expected inputs, it is necessary only to recognize the type of input with a template matching mechanism and then to use the correct predicted error to drive the system. Suggested here is an alternate approach to the realization of a near-ideal error prediction controller, one designed using Neural Networks. Neural Networks are good at recognizing patterns such as system responses, and the back-propagation architecture makes use of a template matching scheme. In using this type of error prediction, it is assumed that the system error responses be known for a particular input and modeled plant. These responses are used in the error prediction controller. An analysis was done on the general dynamic behavior that results from including a digital error predictor in a control loop and these were compared to those including the near-ideal Neural Network error predictor. This analysis was done for a second and third order system
An assessment of technology alternatives for telecommunications and information management for the space exploration initiative
On the 20th anniversary of the Apollo 11 lunar landing, President Bush set forth ambitious goals for expanding human presence in the solar system. The Space Exploration Initiative (SEI) addresses these goals beginning with Space Station Freedom, followed by a permanent return to the Moon, and a manned mission to Mars. A well designed, adaptive Telecommunications, Navigation, and Information Management (TNIM) infrastructure is vital to the success of these missions. Utilizing initial projections of user requirements, a team under the direction of NASA's Office of Space Operations developed overall architectures and point designs to implement the TNIM functions for the Lunar and Mars mission scenarios. Based on these designs, an assessment of technology alternatives for the telecommunications and information management functions was performed. This technology assessment identifies technology developments necessary to meet the telecommunications and information management system requirements for SEI. Technology requirements, technology needs and alternatives, the present level of technology readiness in each area, and a schedule for development are presented
Photovoice and House Meetings Within Participatory Action Research
Participatory action research (PAR) is an epistemology where community members and researchers collaborate to (a) determine the problem to be researched, (b) collect data, (c) analyze data, (d) come to a conclusion, (e) determine an intervention, (f) implement the intervention, and (g) evaluate the intervention (Fals Borda, 1987). We refer to PAR as an epistemology rather than as a method because most PAR theorists view it as a way for those typically situated outside of science to insert their lived experiences and perspectives into the process of knowledge construction (Fals Borda, 1987). Specifically, PAR allows for the democratization of knowledge production by engaging multiple constituents. Through this PAR process, problem definitions shift, thus posing meaningful implications for community-based interventions and social action that focuses on addressing community members’ needs. Indeed, some argue that PAR is an epistemology that is intimately connected to empowerment and social change (Fals Borda, 1987).
We begin our chapter by discussing the two methods within the PAR process, specifically, how photovoice and house meetings work as tools toward social action and empowerment. We highlight some of the relevant literature where these tools have been used. For each method we discuss the steps involved in the process, as well as the benefits and challenges of each. Next, we provide reflections from two of our participant-researchers, who are also coauthors. We end the chapter with implications for community-based PAR and consider how photovoice and house meetings work as tools toward critical consciousness, empowerment, and social action
NASA gateway requirements analysis
NASA devotes approximately 40 percent of its budget to R&D. Twelve NASA Research Centers and their contractors conduct this R&D, which ranges across many disciplines and is fueled by information about previous endeavors. Locating the right information is crucial. While NASA researchers use peer contacts as their primary source of scientific and technical information (STI), on-line bibliographic data bases - both Government-owned and commercial - are also frequently consulted. Once identified, the STI must be delivered in a usable format. This report assesses the appropriateness of developing an intelligent gateway interface for the NASA R&D community as a means of obtaining improved access to relevant STI resources outside of NASA's Remote Console (RECON) on-line bibliographic database. A study was conducted to determine (1) the information requirements of the R&D community, (2) the information sources to meet those requirements, and (3) ways of facilitating access to those information sources. Findings indicate that NASA researchers need more comprehensive STI coverage of disciplines not now represented in the RECON database. This augmented subject coverage should preferably be provided by both domestic and foreign STI sources. It was also found that NASA researchers frequently request rapid delivery of STI, in its original format. Finally, it was found that researchers need a better system for alerting them to recent developments in their areas of interest. A gateway that provides access to domestic and international information sources can also solve several shortcomings in the present STI delivery system. NASA should further test the practicality of a gateway as a mechanism for improved STI access
