Online newspapers business models in Spanish scientific journals. A review and suggestions for future research

Using a hierarchical cluster analysis and a deep literature review of Spanish scientific journals in communication sciences, we identify three themes for understanding online newspapers business models, and three areas that are particularly interesting for future research. First, the need for a better understanding of the concept of business model and an agreed classification on online newspapers. Second, more rigorous and sophisticated statistical methods to study business models on online newspapers and all its levels of analysis, and third, the combination of theoretical frameworks that link management and journalism disciplines.A través de un análisis clúster jerárquico y una profunda revisión literaria de las principales revistas científicas españolas en materia de ciencias de la comunicación, identificamos tres temas principales para la comprensión de los modelos de negocio de la prensa digital, y tres áreas que son particularmente interesantes para investigaciones futuras. Primeramente, la necesidad de una mejor comprensión del concepto de modelo de negocio y una clasificación consensuada en la prensa digital. Segundo, la utilización de técnicas estadísticas más sofisticadas y rigurosas con el objetivo estudiar los modelos de negocio de la prensa digital y todos sus niveles de análisis, y tercero, la combinación de marcos teóricos que unan los estudios sobre gestión y periodismo

Self-assembly of physically crosslinked micelles of poly(2-acrylamido-2-methyl-1-propane sulphonic acid-co-isodecyl methacrylate)-copper(II) complexes

Metal complexes were prepared by the reaction of Cu(II) chloride with sodium salt of random copolymers of 2-acrylamido-2-methylpropane sulphonic acid, AMPS, and isodecyl methacrylate, i-DMA. Composition was varied in the feed to obtain copolymers and their corresponding metal chelates with different content of i-DMA hydrophobic monomer. The copolymers and their metal chelates were characterized by Fourier transformed IR spectroscopy (FTIR) and scanning electron microscopy (SEM) as well as energy-dispersive X-ray spectroscopy (EDS). The X-ray diffraction studies revealed that the polymers and their chelates were amorphous. Also, the stabilities of the copolymers and their metal chelates were investigated using thermal methods such as TGA and DSC analysis. Lower thermal stability was found for the polymer–metal complexes compared to that of the copolymers. Fluorescence spectroscopy was used to further confirm the copolymers and their Cu(II) metal complexes self-aggregate in water. Critical micellar concentrations become lower by metal complexation. A synergistic effect in self-assembly behaviour in water solutions of Cu(II) polycomplexes is attributed to the interplay between hydrophilic–hydrophobic interactions and electrostatic forces with Cu²⁺ ions. Physical crosslinking of polymeric micelles obtained by metal complexation led to more stable micelles. Sodium salt copolymers led to secondary aggregation while ionic crosslinking provided lonely micelles distributed through the substrate as seen by SEM. These results point to a mechanism in which cation-assisted-polymer-modified water structure plays a central role in the phase separation behaviour.The authors would like to thank the Plan Nacional I+D+I (Ministerio de Educación y Ciencia) for financial support (MAT2006-05979) as well as the Comunidad Autónoma de Madrid for the funding through I+D Program (S0505/MAT-0227)

La dimensión comercial de la difusión en las empresas informativas de televisión de ámbito nacional en España (1989-1992)

Este estudio de investigación se fundamenta en la aplicación que las empresas informativas de televisión, de ámbito nacional, han desarrollado durante el periodo 1989-1992, respecto a la comercialización del índice de penetración del mensaje en la audiencia, entendida esta como el producto real de la empresa informativa. La dimensión comercial del índice de penetración del mensaje televisivo en la audiencia sirve de referencia para los canales de televisión, y para sus empresas explotadoras, tve, antena 3 tv, telecinco y canal plus, en estos momentos en españa, a la hora de establecer una estrategia programatica, una línea de financiación, una política de actuación socio-política, y, principalmente, para valorar los resultados producidos que les permita una mayor y mejor competitividad en el mercado, para asegurar óptimos beneficios, ideológicos, sociales, económicos, etc. Todo ello producirá una mayor rentabilidad en la inversión lo que potenciara el sector

Synthesis and association properties in water solution of random copolymers of 2-acrylamido-2-methyl-1-propane sulfonic acid and isodecyl methacrylate—potential application as surfactants in micellar-enhanced ultrafiltration processes

Hydrophobically modified water-soluble polymers have been prepared by copolymerization of 2-acrylamido-2-methylpropane sulfonic acid (AMPS) and isodecyl methacrylate (iDMA) in N,N-dimethylformamide under nitrogen atmosphere, varying the composition feed. Fluorescence spectroscopy was used to further confirm the copolymers self-aggregate in water. Critical concentration of the self-aggregate formation (CAC) decreased by increasing the molar fraction of iDMA in the AMPSco copolymers and varied between 1.20 and 0.04 g/L depending on the degree of hydrophobic modification. Hence, copolymer composition and charge density allowed tuning the pseudomicellar characteristics of these new amphiphilic copolymers. The addition of a salt or a low-molecular-weight surfactant was studied. Binding of CTAB to the AMPSco copolymers leads to a high decrease of CAC, i.e., 0.006 g/L. Effect of the composition in the viscosimetric behavior of the hydrophobically modified copolymers AMPSco was investigated. The removal of single metal ions, Cu²⁺, and m-cresol from aqueous solutions by ultrafiltration with the help of the copolymers was investigated. Equilibrium dialysis experiments demonstrate that the formation of hydrophobic microdomains can be used to control the sequestration of foulants, and thus these novel copolymers have potential application as polymeric surfactants in micellar-enhanced ultrafiltration processes for water purification

Structural Analysis of the Xinhua Information Agency in the 21st Century

A media company or mass media is a communication channel dedicated to in- forming its audience about current facts and events. People need to be informed about political, social, economic, local, international, and other events. This in- formation can be used to make business and governmental decisions, to influence the way we see the eyes of the environment we live in, and to allow us to remain cognizant of what is happening in the world. The investigation of the structural and commercial strategies applied by Xinhua during the last 20 years allowed us to reach the main objective of this study, which could reveal a company with a long history of more than 90 years, able to evolve and adapt to its environment, to changes in the media and to new technologies, so as to be able to compete inter- nationally with other institutions in the world. This research has enabled us to find some data of great value to academics in terms of technological breakthroughs generated by media, information agencies and Internet communication technologies

Comparative Analysis of Xinhua News and European News

One major difference in China compared to the media sector in Europe and Spain is that the Chinese media has significant restrictions on the distribution of non-compliant content, and information is processed with the approval of the Chinese government for information presented to media consumers. In each European country, there exists a great variety of media that present a diversity of information, segmented according to the type of interest of the consumer, in terms of information, entertainment, leisure, etc., which in turn can be divided into local media. However, many media do not reach internationally nor have an international reach, while many Chinese media have a large reach and are able to write in several languages

La función de ídolo de Jon Rahm en la repercusión mediática del Open de España de Golf 2018

La celebración del Open de España 2018 supuso la recuperación de un torneo que nació en 1912 y ha vivido 91 ediciones, pero que en 2017 no se celebró por falta de patrocinadores. Este artículo es resultado de una investigación de las tres universidades públicas de Madrid en las que se estudia Periodismo, y consecuencia del interés de estos centros de enseñanza superior por el deporte del golf. Se analiza la importancia de la presencia de un deportista como Jon Rahm, que provocó la asistencia de casi 50.000 personas durante la semana de competición. Un estudio fundamentado en los impactos informativos en medios impresos de consumo y con distribución nacional de este Open de España en los dos últimos años de competición (2016 y 2018), que valora si la participación de un nuevo ídolo deportivo permite que este torneo vuelva al escenario internacional y el golf adopte una nueva mirada social no solo como deporte competitivo sino como herramienta educativa y de ocio
