O estudo orienta-se a partir dos conceitos de vídeo-ativismo, jornalismo cidadão, movimentos sociais em rede, documentário, e suas inter-relações no contexto contemporâneo das mídias sociais e tecnologias móveis. A metodologia adotada é a análise fílmica, com o estudo dos elementos constitutivos do documentário. A partir dos resultados obtidos, espera-se contribuir para a compreensão do poder da participação cidadã neste novo contexto midiático da web 2.0. / Abstract: This dissertation aims to analyze and discuss the role of video activism and their network connections, in a media ecology at the brazilian protests of 2013, and as a research subject the documentary 20 cents, director Tiago Tambelli produced collaboratively, from the creation of a group of people on Facebook. The study is guided from the video-activist concepts, citizen journalism, social movements networking, documentary, and their interrelationships in the contemporary context of social media and mobile technologies. The methodology used is the film analysis, to the study of the elements of the documentary. From the results obtained, it is expected to contribute to the understanding of the power of citizen participation in this new media context of web 2.0. / Mestre

A multiple baseline across behaviors design was used to test the effectiveness of a treatment package involving the use of a videotape recorder to improve the performance of college women volleyball players. The subjects were four highly skilled athletes, as evidenced by thei.r participation in the University of the Pacific volleyball program, ranked second nationally during the 1980-81 season. The treatment package consisted of the following: (a) zooming in with a video camera on particular aspects of the players' performances; (b) attempts to change only one aspect of the performance of a skill rather than the entire skill; (c) cueing and corrective feedback provided by the coach during the players' viewing of the resulting videotapes; (d) the players immediately correcting their errors in performance after viewing the videotapes and (e) multiple viewings by the players of videotapes of their correct performances of the volleyball skills. The results indicated that all of the subjects benefited from the videotape treatment package. Two of the players showed improvement in the two volleyball skills for which the treatment was given. The other two players showed improvement in one of the two volleyball skills for which the treatment was given. For three of the four players their improved practice performances with the videotape treatment also resulted in improved performances during scrimmages for at least one of the two target behaviors.

The purpose of this study was to evaluate the results of trained transport nurses being oriented to a new helicopter by a video presentation and reference guide manual educational program when compared with trained transport nurses being trained by actual hands-on demonstration. Using a posttest-only design and the t test for independent samples, it was found that the two groups of nurses did not differ statistically (t (9) = 0.318, p < .051).

The purpose of this study was to examine the effects of diabetic teaching using methods of videotape instruction in the hospital. The study focused on measuring the amount of knowledge gained between diabetic patients who viewed a videotape program with and without the presence of a health educator. Data collected for each patient consisted of: age, sex, method of regulating their diabetes i.e. (insulin, oral pills and diet), degree of impairment during hospitalization, number of years each patient has known to have diabetes, prior hospitalization because of diabetes, prior diabetic education, and prior viewing of a videotape on avoiding diabetic complications. In a pre-test/post-test design, 32 patients were randomly assigned to one of two groups. Patients in group I received diabetic teaching using a videotape program without a health educator present, while patients in group II received diabetic teaching using a videotape program along with a health educator present. The post-test was administered on the day following the teaching. A significant increase in knowledge scores (p < .05) was demonstrated on the post-tests taken on the day after viewing the videotape program. A comparison was made between the two groups and results showed no significant difference in knowledge gain between them. It was interesting to note that the presence of the educator was apparently needed for significant knowledge gain scores (F = 7. 13, p < .05) in subjects who had reported to have had prior diabetic education compared to the group of subjects who reported that they had received no previous diabetic education. It would seem that the increased knowledge should serve as a first step to improved health. However, this study in no way demonstrated that the knowledge did lead to improved diabetic control. Perhaps the greatest success of the video program was that the patients expressed an interest in viewing the program and learning about the avoidance of diabetic complications. / M.S.

Thesis (MScSportSc)--Stellenbosch University, 2004. / ENGLISH ABSTRACT: Feedback is critical for motor skill learning. Knowledge of performance (KP) In the form of verbal feedback is the most commonly used type of augmented feedback. Advances in technology have made it possible for coaches to utilise video-supported feedback with athletes with the intention of accelerating the learning process. The use of videotape replay has been an effective aid under some circumstances. Recent commercially available products offer digital analysis that may be even more successful than ordinary video replay in this regard. The purpose of this study was to determine the effectiveness of knowledge of results (KR) and verbal KP with video-support in improving the learning of the tennis serve, when compared to KR with verbal KP only. A total of 18 adults (lOwomen and 8 men) were assessed on their serving technique (6 kinematic variables), accuracy (2 variables) and speed (1 variable). Technique analysis was completed using a commercially available analysis programme. For a short intervention period, one group (n = 10) received KR with verbal feedback only, while the other group (n = 8) received KR plus verbal feedback with video support. The subjects were tested after the intervention to see what changes had occurred with regards to the speed, accuracy and technique of their serves. No significant differences were found for any of the variables, leading to the conclusion that the amount oftime spent in the intervention programme must be extended in order to possibly achieve significant effects on performances. / AFRIKAANSE OPSOMMING: By die aanleer van motoriese vaardighede is terugvoer van kritiese belang. Verbale terugvoering is die mees algemene vorm van kennis oordraging aan die uitvoerder. Verbetering in tegnologie het dit nou moontlik gemaak vir afrigters om videoondersteunde terugvoer met atlete te gebruik, met die doelom die leerproses te versnel. Die gebruik hiervan is in sekere situasies 'n effektiewe hulpmiddel. Kommersiële produkte wat tans beskikbaar is bied die moontlikheid van digitale ontledings, wat dalk meer suksesvol kan wees as slegs die terugspeel van 'n video aan die uitvoerder. Die doel van hierdie studie was om die doeltreffendheid van kennis van resultate (knowledge of results) en verbale terugvoering met video-ondersteuning in die verbetering van die tennis afslaan te meet, en dit dan te vergelyk met kennis van resultate waar net verbale terugvoering verskaf is. 'n Totaal van 18 volwassenes (It) vroue en 8 mans) se afslaantegniek (6 kinematiese verandelikes), akkuraatheid van afslaan (2 verandelikes) en die spoed van die afslaan (1 verandelike) is nagegaan. Tegniekontleding is met die gebruik van 'n komersieël beskikbare analise-program gedoen. Een groep (n = l O) het kennis van resultate en verbale terugvoer gekry vir 'n kort intervensie periode. Die ander groep (n = 8) het kennis van resultate en video-ondersteunde verbale terugvoer, ook vir 'n kort intervensie tydperk ontvang. Die deelnemers is na afloop van die intervensie tydperk getoets om te bepaal watter veranderinge met betrekking tot spoed, akkuraatheid en afslaantegniek plaasgevind het. Geen beduidende verskille is in enige van die verandelikes gevind nie. Dit gee aanleiding tot 'n gevolgtrekking dat die duur van die intervensieprogram verleng moet word om 'n beduidende effek op uitvoering te kry.
