Periodisme : el redescobriment de la paraula

L'article planteja un debat sobre el possible canvi de paradigma dels estudis de periodisme a partir d'alguns trets comuns en les recerques publicades en l'última dècada. La hipòtesi seria que s'ha passat d'un marc conceptual i analític forjat a partir de la psicologia conductista i la semiòtica estructuralista a un de nou amb arrels en el constructivisme i la sociologia del coneixement. D'aquí naixeria l'anàlisi del periodisme com una activitat institucional on lectors, professionals, líders socials i poders polítics o econòmics negocien un seguit de convencions expressives, lingüístiques i simbòliques, per emparaular la realitat social i satisfer les necessitats informatives de les societats avançades.The article proposes a debate on possible changes in the paradigm of journalism studies based on the common trends indicated in research published over the last decade. The hypothesis would be that it has changed from a conceptual and analytical framework based on behavioural psychology and structuralist semiotics into a new study with roots in constructivism and the sociology of knowledge. It is from here that the analysis of journalism appears as an institutional activity in which readers, professionals, social leaders and political or economic powers negotiate a series of expressive, linguistic and symbolic conventions, to put social reality into words and satisfy an advanced society's needs for information

Anàlisi de l'efecte de la viscositat en el disseny de rotors moleculars fluorescents

Treballs Finals de Grau de Química, Facultat de Química, Universitat de Barcelona, Any: 2024, Tutors: Jaume García Amorós, María Dolores Velasco CastrilloFluorescent molecular rotors have gained popularity over the last 15 years. They are compounds with unique properties based on two moieties linked by a π-conjugated bridge. One moiety is called the stator and has a larger moment of inertia, while the other moiety is called the rotor or rotator, a fluorophore that can form a twisted internal charge transfer state (TICT) after photoexcitation, as it exhibits two different competitive pathways of energy loss towards the ground state: fluorescence emission and non-radiative deexcitation.FMRs are widely used as viscosity probes due to their viscosity-sensitive fluorescence behaviour. In a low viscosity medium, the rotation of the rotor is not hindered and induces the non-radiative relaxation of the excitation energy, resulting in the quenching of the fluorescence intensity. In a higher viscosity medium, the rotation is more hindered and fluorescence intensity is enhanced. The sensitivity to solvent viscosity can be quantified using the established relationship between the viscosity (ƞ) of the medium and the fluorescence intensity contrast (I/I0) or fluorescence quantum yield (ϕFL), known as the Förster-Hoffmann equation where x is the slope of the plot and is related to the viscosity sensitivity of the FMR, and C is an experimental constant related to the dyeThe structure of a fluorescent molecular rotor directly influences its ability to sense local viscosity. A classification of the main families of fluorescent molecular rotors that are going to be studied has been made: julolidine-based, BODIPY-based, cyanine-based and rhodamine-based FMRs. Their structural design and sensitivity to viscosity will be reviewed to determine the best sensors of each dye family, and a comparison will be made to find out the best options as viscosity sensors

Re-dissemination of news and public debate on social networks

The results of a qualitative research study based on 12 focus groups with a total of 106 people about the role of social networks in the consumption of current information are presented. We inquired about the motivation of citizens to interact with the news on social networks, and if they consider them appropriate spaces for public debate. Some findings of this study suggest that social networks are seen as an adequate space to share news and information on matters of public interest; to extend the agenda of topics that focus on the interests of users by allowing them access to topics often silenced in their usual media; and finally, social networks are viewed as more suitable for opinions, rather than public debate

Innovation systems in motion: an early music case

Emerald does not grant permission for this article to be further copied/distributed or hosted elsewhere without the express permission from Emerald Group Publishing LimitedPurpose This study aims to provide an in-depth understanding of the innovation system and the learning processes involved in a very specific cultural field: the production of early music. Design/methodology/approach A single case study of the generic value chain in the music production industry describes and analyses the process and the actors involved in editing a new early music collection resulting from the collaboration between a record company and a public research organization. Findings There is a need for new knowledge in the various stages of performance and publication of a new recording. The early music sector is a knowledge-intensive, science-driven sector that can be characterized as a system because the interactions among actors substantially influence final products. Research limitations/implications The single case study represents a specific sector within the music industry. However, its conclusions can be applied to other fields in the cultural heritage sector. Originality/value The literature on innovation in the cultural field primarily focuses on the relationship between art and information and communication technology (ICT). This paper is novel in analysing a case where scientific knowledge is key to new product development, and suggesting that we need to take account of the interactions among cultural heritage entities, universities and other knowledge production organizations. It concludes that these organizations should be involved institutionally in other aspects of the innovation process.Castro-Martínez, E.; Recasens, A.; Jiménez-Sáez, F. (2013).

Presentación

[ES] El espíritu de la Convergencia Europea que tan bien se encarna en el Espacio Europeo de Educación Superior (EEES) sigue dando lugar a una vasta producción teórica, exclusivamente discursiva y en menor medida apoyada en experiencias y en casos concretos, relacionada con los más diferentes aspectos convocados en diversos medios de expresión: documentos, conferencias, ponencias, reuniones, cursos, encuentros, jornadas y oros espacios de reflexión sobre esta urgente cuestión. Lo que se dice es mucho, mucho más de lo que se hace, por supuesto, pero no siempre lo dicho constituye una aportación al desarrollo de este Espacio de Educación Superior, normalmente instalado en la institución universitaria. Como suele ser frecuente, los discursos preceden a la práctica y, en tanto que ésta suele ser con frecuencia resultado y reflejo de normativas y preceptos, no puede extrañar que lo dicho hasta ahora-discursos, reflexiones, argumentos y teorías- vaya muy por delante de lo hecho, de experiencias, proyectos y prácticas.Esteban Albert, M.; Sáez, J.
