Requirements gathering for tools in support of storyboarding in user experience design

Storytelling is often used support communication in early User Experience (UX) design, and the resulting stories are frequently visualized in the form of storyboards. However, storyboarding, the creation of storyboards, has also been identified as an important obstacle to the adoption of storytelling in UX design. Most UX designers do indeed not possess the drawing skills needed to produce professionally-looking storyboards. A problem that can be potentially overcome (or at least ameliorated) by using alternative (digital) storyboarding tools. A study into the user acceptance of existing tools is introduced in this paper. The results show that while traditional tools like pen and paper are still very much valued, digital tools are getting increasingly popular. We identify important limitations of existing tools and formulate requirements for future storyboarding tools.</p

Selecting stimuli parameters for video quality studies based on perceptual similarity distances

This work presents a methodology to optimize the selection of multiple parameter levels of an image acquisition, degradation, or post-processing process applied to stimuli intended to be used in a subjective image or video quality assessment (QA) study. It is known that processing parameters (e.g. compression bit-rate) or technical quality measures (e.g. peak signal-to-noise ratio, PSNR) are often non-linearly related to human quality judgment, and the model of either relationship may not be known in advance. Using these approaches to select parameter levels may lead to an inaccurate estimate of the relationship between the parameter and subjective quality judgments – the system’s quality model. To overcome this, we propose a method for modeling the relationship between parameter levels and perceived quality distances using a paired comparison parameter selection procedure in which subjects judge the perceived similarity in quality. Our goal is to enable the selection of evenly sampled parameter levels within the considered quality range for use in a subjective QA study. This approach is tested on two applications: (1) selection of compression levels for laparoscopic surgery video QA study, and (2) selection of dose levels for an interventional X-ray QA study. Subjective scores, obtained from the follow-up single stimulus QA experiments conducted with expert subjects who evaluated the selected bit-rates and dose levels, were roughly equidistant in the perceptual quality space - as intended. These results suggest that a similarity judgment task can help select parameter values corresponding to desired subjective quality levels

Strategic approach to psychotherapeutic intervention with male institutionalized white adolescents to control absconding

Bibliography: pages 92-98.Using a systems theoretical orientation the objective of this study was to implement a strategic approach for psychotherapeutic intervention with six male institutionalized white adolescents at a local custodial school. It was hypothesized that a strategic approach would control absconding for the duration of the investigation. Surveys of the literature were undertaken to provide the background to psychotherapeutic intervention with adolescents in custodial institutions, strategic psychotherapy and absconding. Absconding was selected as the condition for evaluating the interventions because it was an unambiguous indicator of school-based recidivism, viz., the adolescent was either on the property or he was not. The study was structured as a design-and-demonstrate investigation. Audiotape recordings were made during the sessions. Transcriptions of characteristic procedures and sequences of the strategic approach to psychotherapeutic intervention were presented, inter alia, paradoxes, reframing, metaphors, rituals, the declaration of therapeutic impotence. Evaluation of the interventions was based on follow-up interviews with the subjects and a qualitative analysis of risk of absconding aver the course of the intervention process. At the end of the investigation there was some evidence which suggested that five out of the six subjects were not as committed to absconding as they had claimed to be at the beginning of the study. The design of the study did not allow for the conclusion that the strategic approach for controlling absconding was of greater merit than any other form of intervention or no intervention at all. It was noted, however, that twelve of the eighteen potential subjects for the study indicated that they would abscond as soon as the opportunity arose. Therefore it was recommended that the issue of absconding be given priority in therapy on the admission of each new pupil. Given a strategic approach to addressing the issue of absconding in therapy, attention was drawn to a major aim of this type of intervention, viz., to generate a sense of personal autonomy. Hence a further recommendation was that once a pupil had made a commitment not to abscond, his sense of autonomy would need to be supported by an expeditious transfer to one of the more open hostels

Aprender a aprender desde la biblioteca: barreras sociales y culturales para una sociedad del conocimiento. Experiencias e impresiones de la biblioteca Max Aub del Instituto Cervantes de Argel.

Of what it forms they influence the social and cultural values in the behavior of the readers of the same community. In I make concrete we analyze to the university users that there comes to the Library Max Aub of the Institute Cervantes of Algiers in his relation with the space, the services and his personnel. A step is a question itself to go beyond the analysis of the digital gap; we face a cognitive gap. In addition deno to be able to use a computer, what elements difcultan a learning for all during the whole life?. The model of company, the university and the family explain many of the behaviors and common attitudes in these users turning them into defenseless and dependent readers
