The aim of this study is to translate and validate the instrument Requirement for Directed Attention (RDA), developed by Guirardello, into Brazilian culture. The instrument, comprised of 39 items, addresses situations in the work environment of critical care and medical-surgical units that demand the nurse's direct attention. The methodological approach consists of the following steps: (a) tran...

We are engaged in the deve lopment of systems capable of analyzing short narrat ive messages dealing with a limited domain and extract ing the informat ion conta ined in the narrat ive. These systems are initially being applied to messages describing equ ipmen t failure. This work is a joint e f fo r t of New York Universi ty and the System Deve lopmen t Corp . for the Strategic Computing Progr...

Recen t studies on cytoplasmic microtubules have provided evidence for regarding t hem as gel components susceptible to solational weakenings. Micro tubule s tructure in various cell types has been shown to be sensitive to temperature , pH, pressure, and other envi ronmenta l conditions (Masser and Philpott , 1966; Ti lney et al., 1966; Ti lney and Porter, 1967). In the present work, the sciati...

Abs t rac t : Most so f tware systems use simple text f i les to represent the cur rent state of an evolv ing design. We propose that layered ne tworks provide a much bet ter medium to represent the design of a so f tware system and its documenta t ion . PIE is an exper imenta l personal in format ion envi ronment wh ich prov ides users w i th descr ip t ive s t ruc tu res for documents and pro...

Correcting satellite imagery for atmospheric effects is a common procedure today. Indeed there are many techniques and software applications that offer atmospheric correction processes. This study compared several techniques (apparent reflectance, dark-object subtraction, Cos(t), and the full cost model) in both Idrisi and ENVI software to determine the level of similarity between resulting ima...

This research paper focuses on the relationship between flow experience and multimodal learning environments. Flow experience has been defined as the state in which an individual feels completely absorbed and fully engaged in an activity. This concentration and complete engagement can lead to optimal learning. Several scholars in the areas of distance learning [2] and game-based learning [3] hi...

The hybrid visualization and interaction tool EarthScape is presented here. The software is able to display simultaneously LiDAR point clouds, draped videos with moving footprint, volume scientific data (using volume rendering, isosurface and slice plane), raster data such as still satellite images, vector data and 3D models such as buildings or vehicles. The application runs on touch screen de...

Participatory sensing is a promising new low-cost approach for collecting environmental data. However, current large-scale environmental participatory sensing campaigns typically do not coordinate the measurements of participants, which can lead to gaps or redundancy in the collected data. While some work has considered this problem, it has made several unrealistic assumptions. In particular, i...
