Jóvenes en la sociedad del miedo: miradas sobre medios, miedos y jóvenes en el Ecuador

ResumenSe plantea un análisis de la mirada de miedo e inseguridad que los medios de comunicación construyen en relación a los y las jóvenes y a las culturas juveniles en el Ecuador. A partir dela referencia al tratamiento del incendio de la discoteca Factory en el transcurso de un concierto de rock en abril del 2008, en la ciudad de Quito. La mirada de los medios contribuye a la construcción del miedo social hacia las personas jóvenes. Finalmente, se plantea que la mirada de los estudios culturales en relación con temas de juventud permite superar formas tradicionales de tratar este tema, precisamente por su naturaleza interdisciplinar.Palabras clave: culturas juveniles, jóvenes, medios de comunicación, miedo social, Ecuador.AbstractAn analysis on the view of fear and insecurity that mass media builds in relation with young people and juvenile cultures from the analysis of the treatment of the fire at the “Factory” discotheque duringa rock concert in Quito on April 2008, is proposed. It is proposed that the mass media’s outlook contributes to the social construction of the social fear towards young people. Finally, it is stated thatthe perspective of cultural studies on youth topics break off traditional forms of dealing with the topic due to tis interdisciplinary nature.Keywords: juvenile cultures, youth, mass media, social fear, Ecuador.

El grito de Calibán. Del cinematógrafo al proyecto teleSur: la construcción de lo latinoamericano en la comunicación audiovisual regional

This essay analyzes on the importance of TeleSur TV Station (founded in 2005), in the historical context of the development of audio-visual means of communication in Latin America, as well as the debates about the influence of mass media in the process of cultural identity raising-up. It proposes the thesis that the project of Tele- Sur plays a key role in the shaping of a new international order on communication that allows the protection of the cultural diversity of Latin American nations and democratizes the world’s information flows in the neoliberal globalization stage.

Cause celebri, giustizia penale e informazione. La giustizia penale nello specchio dell'informazione giornalistica

La tesi approfondisce gli aspetti problematici del rapporto tra processo penale e informazione giornalistica. Si è così ritenuto opportuno suddividere la ricerca in due sezioni, una casistica, l’altra prettamente teorica. Nella sezione teorica si è posta l’attenzione sulle questioni più dibattute: tutela della verginità cognitiva del giudice, dei segreti processuali, della libertà di cronaca, della riservatezza di quanti siano anche solo occasionalmente accostati ad un’indagine penale, dell’autodeterminazione delle persone che partecipano al processo e del sereno svolgimento di quest’ultimo. Il fine ultimo è stato quello di porre sotto esame gli attuali equilibri delineati dal codice. Laddove si è potuta osservare una inadeguatezza legislativa si è tentato di avanzare una proposta di riforma. Sul punto, da un lato si sono potute osservare alcune incongruenze oggi riscontrabili nell’art. 114 c.p.p. Il tutto nella ritrovata consapevolezza che il dilemmatico rapporto tra processo e mass media può rischiare finanche di impattare sulle dinamiche probatorie, col serio rischio di inquinamento di alcune prove dichiarative. Il futuribile testimone esposto all’influenza dell’opinione pubblica può restarne scosso o turbato, al punto da potere soffrire di un’alterazione mnemonica del suo ricordo. Non per ultimo, di ausilio si è mostrata la prospettiva comparata, dalla quale si sono potuti trarre validi spunti per una ideale soluzione dei problemi passati in rassegna. Su questo versante, si è osservato il sistema spagnolo, interessati a cogliere gli equilibri costituzionali sui quali si erge il rapporto tra libertà di cronaca e processo penale e le regole codicistiche in tema di propalazione di atti giudiziari all’opinione pubblica iberica. All’esito, si sono potute trarre le conclusioni ripercorse nel testo.

L'industria del podcast: produzione e contenuti del genere d'inchiesta

L’obiettivo della ricerca è quello di analizzare la forma e i meccanismi del podcasting d’inchiesta, partendo dalla definizione del medium e da alcuni cenni storici. Si cerca quindi di fotografare, il più esaustivamente possibile, il quadro attuale dei generi e delle tipologie di podcast esistenti, tenendo in considerazione la fragilità dei confini tra le categorie. Proprio grazie all’estrema libertà che la produzione di un podcast conferisce al suo creatore, è possibile individuare almeno due modalità principali di distinzione dei generi: per forma o per contenuto. Analizzando più a fondo i vari elementi costitutivi di un podcast, è possibile individuare un terzo criterio di suddivisione: quello per intenzione. In questo modo è possibile identificare almeno altri due generi: il Branded Podcast e il Podcast d’inchiesta. Questo ultimo scaturisce dalla forma e dai contenuti del true crime, incorporando al racconto elementi inediti e trasformando la voce del podcast in azione. Alcuni esempi di podcast d’inchiesta italiani possono essere Polvere, il caso Marta Russo, La bomba e, ovviamente, Veleno. L’analisi del podcast d’inchiesta si focalizza poi sugli aspetti formali e costitutivi del genere, individuando gli elementi che ne compongono la comunicazione. I modi di produzione dei diversi players sono un altro aspetto rilevante dell’indagine: si individuano le podcast companies cosiddette native audio (come per esempio Chora Media o Vois), e chi invece ha aggiunto il podcast ad un’offerta preesistente. Esistono differenze nella produzione tra i due casi? Per quanto riguarda il panorama italiano, è significativo il caso del podcast Veleno prodotto per La Repubblica, in cui Pablo Trincia, assieme ad Alessia Rafanelli, analizza uno dei casi di cronaca nera più discussi e controversi.

Effects of geological inhomogeneity on high Rayleigh number steady state heat and mass transfer in fluid-saturated porous media heated from below

A parametric study is carried out to investigate how geological inhomogeneity affects the pore-fluid convective flow field, the temperature distribution, and the mass concentration distribution in a fluid-saturated porous medium. The related numerical results have demonstrated that (1) the effects of both medium permeability inhomogeneity and medium thermal conductivity inhomogeneity are significant on the pore-fluid convective flow and the species concentration distribution in the porous medium; (2) the effect of medium thermal conductivity inhomogeneity is dramatic on the temperature distribution in the porous medium, but the effect of medium permeability inhomogeneity on the temperature distribution may be considerable, depending on the Rayleigh number involved in the analysis; (3) if the coupling effect between pore-fluid flow and mass transport is weak, the effect of the Lewis number is negligible on the pore-fluid convective flow and temperature distribution, hut it is significant on the species concentration distribution in the medium.

Finite element modelling of reactive mass transport problems in fluid-saturated porous media

We use the finite element method to solve reactive mass transport problems in fluid-saturated porous media. In particular, we discuss the mathematical expression of the chemical reaction terms involved in the mass transport equations for an isothermal, non-equilibrium chemical reaction. It has turned out that the Arrhenius law in chemistry is a good mathematical expression for such non-equilibrium chemical reactions especially from the computational point of view. Using the finite element method and the Arrhenius law, we investigate the distributions of PH (i.e. the concentration of H+) and the relevant reactive species in a groundwater system. Although the main focus of this study is on the contaminant transport problems in groundwater systems, the related numerical techniques and principles are equally applicable to the orebody formation problems in the geosciences.

How new online communication tools and the availability of content influence the audiences and the creative process

We live in a changing world. At an impressive speed, every day new technological resources appear. We increasingly use the Internet to obtain and share information, and new online communication tools are emerging. Each of them encompasses new potential and creates new audiences. In recent years, we witnessed the emergence of Facebook, Twitter, YouTube and other media platforms. They have provided us with an even greater interactivity between sender and receiver, as well as generated a new sense of community. At the same time we also see the availability of content like it never happened before. We are increasingly sharing texts, videos, photos, etc. This poster intends to explore the potential of using these new online communication tools in the cultural sphere to create new audiences, to develop of a new kind of community, to provide information as well as different ways of building organizations’ memory. The transience of performing arts is accompanied by the need to counter that transience by means of documentation. This desire to ‘save’ events reaches its expression with the information archive of the different production moments as well as the opportunity to record the event and present it through, for instance, digital platforms. In this poster we intend to answer the following questions: which online communication tools are being used to engage audiences in the cultural sphere (specifically between theater companies in Lisbon)? Is there a new relationship with the public? Are online communication tools creating a new kind of community? What changes are these tools introducing in the creative process? In what way the availability of content and its archive contribute to the organization memory? Among several references, we will approach the two-way communication model that James E. Grunig & Todd T. Hunt (1984) already presented and the concept of mass self-communication of Manuel Castells (2010). Castells also tells us that we have moved from traditional media to a system of communication networks. For Scott Kirsner (2010), we have entered an era of digital creativity, where artists have the tools to do what they imagined and the public no longer wants to just consume cultural goods, but instead to have a voice and participate. The creativity process is now depending on the public choice as they wander through the screen. It is the receiver who owns an object which can be exchanged. Virtual reality has encouraged the receiver to abandon its position of passive observer and to become a participant agent, which implies a challenge to organizations: inventing new forms of interfaces. Therefore, we intend to find new and effective online tools that can be used by cultural organizations; the best way to manage them; to show how organizations can create a community with the public and how the availability of online content and its archive can contribute to the organizations’ memory.

Detection of metabolite induction in fungal co-cultures on solid media by high-throughput differential ultra-high pressure liquid chromatography-time-of-flight mass spectrometry fingerprinting.

Access to new biological sources is a key element of natural product research. A particularly large number of biologically active molecules have been found to originate from microorganisms. Very recently, the use of fungal co-culture to activate the silent genes involved in metabolite biosynthesis was found to be a successful method for the induction of new compounds. However, the detection and identification of the induced metabolites in the confrontation zone where fungi interact remain very challenging. To tackle this issue, a high-throughput UHPLC-TOF-MS-based metabolomic approach has been developed for the screening of fungal co-cultures in solid media at the petri dish level. The metabolites that were overexpressed because of fungal interactions were highlighted by comparing the LC-MS data obtained from the co-cultures and their corresponding mono-cultures. This comparison was achieved by subjecting automatically generated peak lists to statistical treatments. This strategy has been applied to more than 600 co-culture experiments that mainly involved fungal strains from the Fusarium genera, although experiments were also completed with a selection of several other filamentous fungi. This strategy was found to provide satisfactory repeatability and was used to detect the biomarkers of fungal induction in a large panel of filamentous fungi. This study demonstrates that co-culture results in consistent induction of potentially new metabolites.

On-line mass spectrometry of the electro-oxidation of methanol in acidic media on tungsten carbide

The electro-oxidation of methanol at supported tungsten carbide (WC) nanoparticles in sulfuric acid solution was studied using cyclic voltammetry, potentiostatic measurements, and differential electrochemical mass spectroscopy (DEMS). The catalyst was prepared by a sonochemical method and characterized by X-ray diffraction. Over the WC catalyst, the oxidation of methanol (1 M in a sulfuric acid electrolyte) begins at a potential below 0.5 V/RHE during the anodic sweep. During potentiostatic measurements, a maximum current of 0.8 mA mg(-1) was obtained at 0.4 V. Measurements of DEMS showed that the methanol oxidation reaction over tungsten carbide produces CO2 (m/z=44); no methylformate (m/z=60) was detected. These results are discussed in the context of the continued search for alternative materials for the anode catalyst of direct methanol fuel cells.

Simultaneous analysis of five antidepressant drugs using direct injection of biofluids in a capillary restricted-access media-liquid chromatography-tandem mass spectrometry system

Direct analysis, with minimal sample pretreatment, of antidepressant drugs, fluoxetine, imipramine, desipramine, amitriptyline, and nortriptyline in biofluids was developed with a total run time of 8 min. The setup consists of two HPLC pumps, injection valve, capillary RAM-ADS-C18 pre-column and a capillary analytical C 18 column connected by means of a six-port valve in backflush mode. Detection was performed with ESI-MS/MS and only 1 mu m of sample was injected. Validation was adequately carried out using FLU-d(5) as internal standard. Calibration curves were constructed under a linear range of 1-250 ng mL(-1) in plasma, being the limit of quantification (LOQ), determined as 1 ng mL(-1), for all the analytes. With the described approach it was possible to reach a quantified mass sensitivity of 0.3 pg for each analyte (equivalent to 1.1-1.3 fmol), translating to a lower sample consumption (in the order of 103 less sample than using conventional methods).
