The results of a project on news segmentation at Radio Nacional de España (RNE) carried out by the RTVE Technological Innovation and Media Management areas is presented. The aim of this project is to apply artificial intelligence to automatically transcribe and cut the news items that make up a radio news program. The main goals of this project are to increase the accessibility of the content and to allow its reusability on various platforms and social media. The project was planned in two phases, covering system configuration and service delivery. The minimum quality criteria required were defined in advance, both for automatic voice transcription and for news segmentation. For the speech-to-text process, the highest word error rate (WER) allowed was 10%, while the precision rate for the news segmentation was 85%. System performance in both transcription and segmentation was considered to be sufficient, although a higher degree of accuracy in news cutting is expected in the coming months. The results show that, despite using these quite mature technologies, adjustment and learning processes and human intervention are still necessary. Resumen Se presentan los resultados del proyecto para la segmentación en noticias de los informativos de Radio Nacional de España (RNE) llevado a cabo por el Área de Innovación Tecnológica de Radio Televisión Española (RTVE) en colaboración con la Dirección de Medios de RNE. El objetivo de este proyecto es aplicar la inteligencia artificial para el cortado automático de las noticias que componen un informativo radiofónico, para su posterior difusión en la web de RTVE y en medios de comunicación social. El proyecto se planificó en dos fases: una primera de configuración y ajuste del sistema, y una segunda de prestación del servicio propiamente dicho. Los criterios de calidad mínimos exigibles se definieron previamente, tanto para la transcripción automática del habla a texto, para la que se estableció una tasa de error por palabra máxima (WER) del 10%, como para la segmentación de noticias, para la que se definió una tasa de precisión superior al 85%. El rendimiento del sistema tanto en la transcripción como en la segmentación se considera suficiente, si bien se espera alcanzar un mayor grado de precisión en el cortado de noticias en los próximos meses. Los resultados ponen de manifiesto que, a pesar de ser tecnologías bastante maduras, son necesarios procesos de ajuste y aprendizaje con la intervención humana.

To examine the relationship between bullying and other forms of peer victimization in adolescence and alcohol use or misuse, all the pertinent studies were reviewed. Fourteen databases were searched. Blind assessments of study eligibility and quality were performed by two independent researchers. Seventy-four studies including 2,066,131 participants across 56 countries all over the world and meeting minimum quality criteria that were enough to ensure objectivity and to not invalidate results were analyzed. Across studies, evidence for a significant association between peer victimization and alcohol use or misuse was conflicting. Results were affected by sample size, definition of victim status, specific forms of peer victimization, and specific types of alcohol consumption. There was some evidence for a number of mediating or moderating variables, such as depression, coping, drinking motives, attachment to school, social support, and gender. Findings are discussed according to stress-coping and self-medication hypotheses. Alternative etiological mechanisms are also considered.

The stages of developing the PBL-AfL-S model consist of preliminary research, development or prototyping, and evaluation. The quality criteria of PBL-AfL-S refer to Nieveen (1999), i.e. valid, practical, and effective. The PBL-AfL-S model was piloted in SMA Negeri 3 Klaten in two phases. Tryout 1 was conducted in class XI-IPA 6 and tryout 2 was in class XI-IPA 7. The research instruments consist of: 1) The validity instrument of the model and its learning support tools, 2) the practicality of the teacher’s and students’ activity, and 3) The effectiveness instruments including self-assessment questionnaires, project appraisal sheets, achievement tests, and student response sheets. The results show that the PBL-AfL-S model and learning tools have met the valid, practical and effective criteria. Keywords: Problem based Learning, Assessment; Smartphone

The article presents the results from a systematic observation of and interviews with journalists who produce local radio news program, BandNews FM, in Rio de Janeiro. The objective is to analyze how the gatewatching process is applied to selecting sources from WhatsApp, and to explore the specific nature of work carried out in radio journalism newsrooms. One of the main features of this broadcaster is the large number of public voices selected from the WhatsApp instant messaging application. The data shows popular voices selected for this paper which fit into a particular theme, it shows the collaborative curation with listeners, and it shows the organizational constraints of investigation, highlighted by journalists sitting behind a desk, absent from the stage of the events. Unlike other media vehicles, radio demands continuous updating and decentralization when selecting material to be broadcast. This study points out characteristics that are demanded of journalists who work in radio and the new, newsroom strategies of involving the public via social networking platforms.O artigo apresenta resultados de uma observação sistemática e entrevistas com jornalistas que produzem o radiojornal local da BandNews FM no Rio de Janeiro.

Abstract Adequate fertilizing management is crucial to reach high mango yields that demand a well-defined fertilizer management, including micronutrient such as boron which management is more difficult due to the narrow range between deficiency and toxicity. This way, an experiment was carried out to evaluate the fruit production and quality of mango cv. Palmer as a function of boron fertilizing management in Brazilian semiarid. The experimental design was in randomized blocks with six treatments (strategies for boron fertilizing), as follows: T1 = five sprays with H3BO3 (two first at 0.3% and three at 0.2%); T2 = five sprays with H3BO3 (two first at 0.3% and three at 0.4%); T3 = five sprays with H3BO3 (two first at 0.3% and three at 0.6%); T4 = two sprays with H3BO3 at 0.3% + three fertigations with 10 g of H3BO3 plant-1; T5 = two sprays with H3BO3 at 0.3% + three fertigations with 20 g of H3BO3 plant-1; and T6 = two sprays with H3BO3 at 0.3% + three fertigations with 40 g of H3BO3 plant-1. Boron fertilizing management (foliar spray and fertigation) affects fruit production and quality of mango cv. ‘Palmer’ grown in semiarid. According to the minimum quality criteria required for mango fruit commercialization and the fruit production per plant in semiarid, five sprays with H3BO3 [two first at 0.3% and three at 0.2%] could be recommended.
