Digital marketing actions that achieve a better attraction and loyalty of users: an analytical study

Currently, the digital economy contributes decisively to an increase in competitiveness, especially as a digital transformation involves migrating to new technological models where digital marketing is a key part of growth and user loyalty strategies. Internet and Digital Marketing have become important factors in campaigns, which attract and retain Internet users. This study aims to identify the main ways in which users can be gained and retained by using Digital Marketing. The Delphi method with in-depth interviews was the methodology used in this study. The results of the research show the most important actions for achieving user recruitment and loyalty with Digital Marketing from the opinions of consulted experts. The limitations of this study are those related to the number of experts included in the study, and the number of research papers consulted in the literature review. The literature review and the results of this research are used to propose new solid research with a consolidated critical methodology. This research deals with a new approach that will optimize web technologies for the evolution of user trends, and therefore, will be of academic and professional use for marketing managers and web solution developers. The conclusions of the investigation show the key factors, discarding others that do not affect the optimization of conversions in B2C businesses such as the duration of the session and the rebound percentage. Likewise, the results of the research identify the specific actions that must be carried out to attract and retain users in B2C companies that use the Digital Marketing ecosystem on the Internet. The requirements for companies that wish to implement a model to optimize conversions using the current digital economy are also shown.info:eu-repo/semantics/publishedVersio

The freedom of movement of asylum-seekers within the host State under international and European human rights law

Asylum-seekers in several European States often have to endure policies that make them feel trapped in a specific part of the country or that constrain their movements to such an extent that their situation resembles detention. How can human rights law respond to these practices? This PhD thesis comprehensively examines the right to free movement within the country under international and European human rights law, as well as under the Spanish and German domestic legal systems. With a specific focus on asylum-seekers, the study analyses this issue from four different angles: (1) the travaux préparatoires of the various instruments that enshrine this freedom; (2) the personal scope of the right according to legal doctrine and case law; (3) the material scope of the right, i.e. the distinction between a restriction on movement and a deprivation of liberty; and (4) the safeguards offered by this right. By comparing the protection afforded to asylum-seekers with that extended to nationals and individuals in general, the thesis contributes to the growing literature on migration exceptionalism. Additionally, the exploration of the legal status of asylum-seekers under various treaties and the detailed assessment of the definition of ‘detention’ hold the potential to inform research in other areas of human rights law, including refugee law

Ibero-American Research on Local Development. An Analysis of Its Evolution and New Trends

Local development is a subject that arouses significant interest in the international scientific community in general, and in the Ibero-American one, in particular. The process of globalization has transformed the management of local development, altering the role that is played by local and regional entities, and it is the object of an important follow-up and analysis by academia. This research uses a bibliometric methodology and a fractional counting method, reviewing the 738 articles from the Scopus database in order to understand the state of Ibero-American research on local development, and analyze the scientific literature on the topic. The results show a significant increase in the number of publications in the 21st century, with Spain and Brazil leading the way. In addition, this research provides interesting results regarding the most influential authors on this topic, the most relevant journals, and the most important institutions and funding organizations. There are several areas of knowledge involved since local development is a transversal field, such as Social Science, environment, business, economics, and agriculture. A deep analysis of authors’ keywords identified new trends, linking local development with tourism, education, geotourism, climate change, local sustainable development, social innovation, and creativity, which provides academia with potential new lines of research

Reduced heart rate variability predicts fatigue severity in individuals with chronic fatigue syndrome/myalgic encephalomyelitis

Heart rate variability (HRV) is an objective, non-invasive tool to assessing autonomic dysfunction in chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME). People with CFS/ME tend to have lower HRV; however, in the literature there are only a few previous studies (most of them inconclusive) on their association with illness-related complaints. To address this issue, we assessed the value of different diurnal HRV parameters as potential biomarker in CFS/ME and also investigated the relationship between these HRV indices and self-reported symptoms in individuals with CFS/ME.Peer ReviewedPostprint (published version

Actores regionales de soporte en el fortalecimiento de la cadena de la guadua del eje cafetero

El presente trabajo pretende dar respuesta a la identificación de las problemáticas que se presentan al observar el comportamiento y el apoyo por parte de los actores regionales que están involucrados en el proceso productivo de la guadua a nivel regional, (Eje Cafetero), teniendo en cuenta algunos factores que sobresalen como son la falta de conocimiento respecto al manejo y manipulación de este producto forestal, la falta de rigurosidad en los controles legales respecto a todo el proceso de comercialización y finalmente la falta de interés por un buen aprovechamiento de éste, que se puede denominar como un diamante en bruto, porque ofrece gran cantidad de beneficios y flexibilidad en cuanto al manejo, es allí donde se han identificado las necesidades que constantemente surgen y que deben ser resueltas por medio de entes o actores regionales a través de un apoyo adecuado, para disminuir en lo posible los factores negativos que fueron previamente nombrados. El trabajo fue realizado con la intención de establecer el apoyo brindado por los actores regionales para el fortalecimiento de la cadena de la guadua en el Eje Cafetero, buscando para ello, primero reconocer los actores regionales de soporte en la guadua, luego hacer el análisis del apoyo y soporte brindado por los actores regionales de involucrados en la cadena de la guadua y por ultimo proponer un esquema de relacionamiento entre los actores regionales que dan soporte en la cadena de la guadua del Eje Cafetero y los entes que reciben dicho soporte. El estudio investigó sobre los eslabones a los que apoyan y/o reciben apoyo de la cadena que se han identificado para la guadua y que son: producción (silvicultura), transformación (industrialización) y comercialización la cual se da desde dos variantes la venta de guadua como materia prima y la venta de productos elaborados en guadua

Tensor products of ideal codes over Hopf algebras

We study indecomposable codes over the well-known family of Radford Hopf algebras. We use properties of Hopf algebras to show that tensors of ideal codes are ideal codes, extending the corresponding result given in a previous paper where we study codes as ideals over the family of Taft Hopf Algebras and showing that in this new case, semisimplicity is lost

Heuristic usability evaluation on games: a modular approach

Heuristic evaluation is the preferred method to assess usability in games when experts conduct this evaluation. Many heuristics guidelines have been proposed attending to specificities of games but they only focus on specific subsets of games or platforms. In fact, to date the most used guideline to evaluate games usability is still Nielsen’s proposal, which is focused on generic software. As a result, most evaluations do not cover important aspects in games such as mobility, multiplayer interactions, enjoyability and playability, etc. To promote the usage of new heuristics adapted to different game and platform aspects we propose a modular approach based on the classification of existing game heuristics using metadata and a tool, MUSE (Meta-heUristics uSability Evaluation tool) for games, which allows a rebuild of heuristic guidelines based on metadata selection in order to obtain a customized list for every real evaluation case. The usage of these new rebuilt heuristic guidelines allows an explicit attendance to a wide range of usability aspects in games and a better detection of usability issues. We preliminarily evaluate MUSE with an analysis of two different games, using both the Nielsen’s heuristics and the customized heuristic lists generated by our tool.Unión Europea PI055-15/E0

Video pulse rate variability analysis in stationary and motion conditions

Background: In the last few years, some studies have measured heart rate (HR) or heart rate variability (HRV) parameters using a video camera. This technique focuses on the measurement of the small changes in skin colour caused by blood perfusion. To date, most of these works have obtained HRV parameters in stationary conditions, and there are practically no studies that obtain these parameters in motion scenarios and by conducting an in-depth statistical analysis. Methods: In this study, a video pulse rate variability (PRV) analysis is conducted by measuring the pulse-to-pulse (PP) intervals in stationary and motion conditions. Firstly, given the importance of the sampling rate in a PRV analysis and the low frame rate of commercial cameras, we carried out an analysis of two models to evaluate their performance in the measurements. We propose a selective tracking method using the Viola–Jones and KLT algorithms, with the aim of carrying out a robust video PRV analysis in stationary and motion conditions. Data and results of the proposed method are contrasted with those reported in the state of the art. Results: The webcam achieved better results in the performance analysis of video cameras. In stationary conditions, high correlation values were obtained in PRV parameters with results above 0.9. The PP time series achieved an RMSE (mean ± standard deviation) of 19.45 ± 5.52 ms (1.70 ± 0.75 bpm). In the motion analysis, most of the PRV parameters also achieved good correlation results, but with lower values as regards stationary conditions. The PP time series presented an RMSE of 21.56 ± 6.41 ms (1.79 ± 0.63 bpm). Conclusions: The statistical analysis showed good agreement between the reference system and the proposed method. In stationary conditions, the results of PRV parameters were improved by our method in comparison with data reported in related works. An overall comparative analysis of PRV parameters in motion conditions was more limited due to the lack of studies or studies containing insufficient data analysis. Based on the results, the proposed method could provide a low-cost, contactless and reliable alternative for measuring HR or PRV parameters in non-clinical environments.Peer ReviewedPostprint (published version
