Performance investigation of an OAM-SK optical communication system based on a PCNN-LDPC under atmospheric turbulence
Authors: Chen Wei , Hou Zhengwei , Yang Lixia , Bo Yong , Guo Lixin
Published: January 2025

This paper proposes a probabilistic convolutional neural network-low density parity check (PCNN-LDPC) demodulation scheme for orbital angular momentum shift keying free-space optical (OAM-SK-FSO) communication systems, with a focus on its bit error rate (BER) performance. Initially, the original information sequences were encoded by a low-density parity check (LDPC) and transformed into superposition state Laguerre Gaussian (LG) beams using a 16-Ary mapping scheme. The transmission of LG beams through atmospheric turbulence was then simulated using the power spectral inversion method, and the dataset was constructed and trained using a convolutional neural network (CNN). During demodulation, the CNN adaptive demodulator was integrated with the LDPC decoding algorithm. Classification probabilities from the CNN adaptive demodulator were used in the LDPC decoding process to enhance the channel estimation credibility. The computational results demonstrate that the BER of the PCNN-LDPC significantly outperforms both the CNN adaptive demodulator and CNN-LDPC demodulation strategy. Additionally, the performances of three LDPC decoding algorithms—min-sum (MS), normalized min-sum (NMS), and offset min-sum (OMS)—are compared, revealing that the probabilistic convolutional neural network-normalized min-sum (PCNN-NMS) achieves the best BER performance, highest convergence efficiency, and greatest decoding stability. These findings provide theoretical references and technical support for studying the BER performance of OAM-SK-FSO communication systems.
Reconfigurable intelligent surface-aided positioning-centered multi-LED integrated visible light communication and positioning system
Authors: Wu Qi , Zhang Jian , Zhang Yan-yu , Xin Gang , Li Dun
Published: January 2025

This paper investigates a reconfigurable intelligent surface (RIS)-aided integrated visible light communication and positioning (VLCP) system, which aims to reduce sensitivity to line-of-sight (LoS) blockage in visible light and simultaneously achieve capabilities for both visible light communication (VLC) and visible light positioning (VLP). The framework of this system is divided into three parts: positioning, channel state information (CSI) estimation, and data transmission. When the LoS links are present, due to the potential adverse positioning effects RIS caused in this scenario, the RIS only plays a role in assisting the communication. Meanwhile, the positioning process is based on the received signal strength (RSS) information from the LoS transmission. If the LoS links are blocked, the RIS provides added non-line-of-sight (NLoS) positioning signals and achieves subsidiary communications accordingly. The Cramer-Rao lower bound (CRLB) on the positioning result is derived and the CSI estimation is conducted based on the results provided by the positioning schemes to reduce the pilot overhead. The achievable rate is evaluated based on the estimated CSI. The configurations of RIS parameters and the power allocated to positioning and communication are jointly optimized to minimize the CRLB while satisfying constraints on the maximum tolerable outage probability, RIS parameter acquisition, and total transmit power. To address this non-convex optimization problem, we proposed an alternative optimization (AO) algorithm to optimize the RIS assignment matrix and the power coefficient alternatively. We employ the worst-case distribution of the Conditional Value-at-Risk (CVaR) along with successive convex approximation (SCA) techniques to derive feasible solutions of the power coefficient optimization subproblem. Meanwhile, we optimize the RIS assignment matrix based on the principle of maximum received power chosen (MRPC). Simulation results demonstrate the influence of RIS in the positioning process in our proposed VLCP system with or without the presence of LoS links, and meanwhile, the relationship between communication performance and positioning performance is validated through the simulations. From the simulation results, the RIS-aided VLCP system can be verified as a viable option for the upcoming era of sixth-generation (6G) technology.
Electroluminescence in n-type GaAs unipolar nanoLEDs
Authors: Jacob Bejoys , Azevedo João , Nieder Jana B. , Romeira Bruno
Published: January 2025

In this Letter, we report the observation of electroluminescence (EL) at ∼866 nm from n-i-n unipolar (electron-transporting) III-V GaAs nanoLEDs. The devices consist of nanopillars with a top diameter of 166 nm, arranged in a 10 × 10 pillar array. Hole generation through impact ionization and Zener tunneling is achieved by incorporating an AlAs/GaAs/AlAs double-barrier quantum well within the epilayer structure of the n-i-n diode. Time-resolved EL measurements reveal decay lifetimes >300 ps, allowing us to estimate an internal quantum efficiency (IQE) higher than 2% at sub-mA current injection. These results demonstrate the potential for a new, to the best of our knowledge, class of n-type nanoscale light-emitting devices.
Refined Kerr-effect-based high-dimensional quantum gate
Authors: Du Fang-Fang , Ren Xue-Mei , Fan Gang , Guo Jing
Published: January 2025

High-dimensional quantum gates not only extend the existing quantum computing framework but also serve as a vital component in a range of quantum technologies. In the study, a 4 × 4-dimensional controlled-NOT (CNOT) gate is presented based on the assistance of a weak cross-Kerr medium, utilizing only two degrees of freedom (DoFs) with two photons. Specifically, the control qudits are encoded in the photonic polarization DoF, while the target qudits are encoded in the path DoF of the two photons. Notably, the circuit is constructed using only two times of the Kerr medium, outperforming a previous design that required six times, which simplifies the entire circuits. Furthermore, the fidelity and success probability of the proposed protocol are near 1 when the influence factors take the appropriate value.
Inhibiting ion migration in strontium–lead halide perovskite for pure-blue emission: a first-principle and experimental study
Authors: Qi Yaqi , Han Shulin , Cao Ying , Qiu Shuai , Song Yuzhi , Wang Chuankui , Cai Lei
Published: January 2025

Bromide–chloride mixed perovskites have garnered significant attention as a direct and efficient material for achieving pure-blue emission. However, the complex problem of halide migration in mixed halide perovskites presents a significant obstacle to achieving stable electroluminescence (EL) spectra. Here, we investigate the mechanism of partially replacing the B-site Pb2+ with the non-toxic Sr2+ to achieve pure-blue emission based on first principles. The ion mobility activation energy of Sr2+ is 1.23 eV, which is an order of magnitude greater than that of halogens. Meanwhile, the incorporation of Sr2+ triples the activation energy for halogen migration. Furthermore, the halide defect formation energy increases from 4.75 eV to 5.62 eV, thereby reducing ion migration channels. Transient absorption spectroscopy demonstrates that suppressing the ion mobility pathway and enhancing ion mobility activation energy promotes the perovskite film to exhibit excellent spectral stability under laser pumping. Our work provides insights for the development of highly stable and eco-friendly perovskite devices.

Identifying the driver nodes of a network has crucial implications in biological systems from unveiling causal interactions to informing effective intervention strategies. Despite recent advances in network control theory, results remain inaccurate as the number of drivers becomes too small compared to the network size, thus limiting the concrete usability in many real-life applications. To overcome this issue, we introduced a framework that integrates principles from spectral graph theory and output controllability to project the network state into a smaller topological space formed by the Laplacian network structure. Through extensive simulations on synthetic and real networks, we showed that a relatively low number of projected components can significantly improve the control accuracy. By introducing a new low-dimensional controllability metric we experimentally validated our method on N = 6134 human connectomes obtained from the UK-biobank cohort. Results revealed previously unappreciated influential brain regions, enabled to draw directed maps between differently specialized cerebral systems, and yielded new insights into hemispheric lateralization. Taken together, our results offered a theoretically grounded solution to deal with network controllability and provided insights into the causal interactions of the human brain.

Anxiety is highly prevalent among college communities, with significant numbers of students, faculty, and staff experiencing severe anxiety symptoms. Digital mental health interventions (DMHIs), including Cognitive Bias Modification for Interpretation (CBM-I), offer promising solutions to enhance access to mental health care, yet there is a critical need to evaluate user experience and acceptability of DMHIs. CBM-I training targets cognitive biases in threat perception, aiming to increase cognitive flexibility by reducing rigid negative thought patterns and encouraging more benign interpretations of ambiguous situations. This study used questionnaire and interview data to gather feedback from users of a mobile application called "Hoos Think Calmly" (HTC), which offers brief CBM-I training doses in response to stressors commonly experienced by students, faculty, and staff at a large public university. Mixed methods were used for triangulation to enhance the validity of the findings. Qualitative data was collected through semi-structured interviews from a subset of participants (n = 22) and analyzed thematically using an inductive framework, revealing five main themes: Effectiveness of the Training Program; Feedback on Training Sessions; Barriers to Using the App; Use Patterns; and Suggestions for Improvement. Additionally, biweekly user experience questionnaires sent to all participants in the active treatment condition (n = 134) during the parent trial showed the most commonly endorsed response (by 43.30% of participants) was that the program was somewhat helpful in reducing or managing their anxiety or stress. There was overall agreement between the quantitative and qualitative findings, indicating that graduate students found it the most effective and relatable, with results being moderately positive but somewhat more mixed for undergraduate students and staff, and least positive for faculty. Findings point to clear avenues to enhance the relatability and acceptability of DMHIs across diverse demographics through increased customization and personalization, which may help guide development of future DMHIs.
The ambiguous role of partially protected marine protected areas in Australia: Results from a systematic literature review
Authors: Phillips Genevieve A. C. , Ogier Emily , Dutton Ian , Barrett Neville , Krueck Nils C. , Hartmann Klaas
Published: January 2025

Marine protected areas (MPAs) are an important tool in helping to protect biodiversity in the oceans. Recent ratification of the Kunming-Montreal Global Biodiversity Framework (GBF) has ensured that globally we are committed to effectively protecting 30% of the world’s oceans by 2030, in MPAs. In Australia there is considerable interest in the potential benefits that partially protected areas (PPAs) may provide. However, a consistent definition of a PPA is currently lacking, and urgently needed to conduct quantitative analyses of PPAs. We conducted a systematic literature review to understand the current knowledge surrounding PPAs and their potential benefits. We define a PPA, characterise PPA implementation in Australia, and present results for the outcomes of PPAs in terms of ecological, economic, and social indicators. Our review suggests that although 45% of Australia’s marine environment is within MPAs, 61% of MPAs provide only partial protection. The Northern Territory (100%), New South Wales (81%), and Queensland (79.8%) have the highest percentage of MPAs that are partially protected, compared to Tasmania which has the smallest percentage of partially protected MPAs (13.12%). Tasmania also has the smallest percentage cover of MPAs (6.49% state waters). Most PPA management plans did not contain quantifiable Key Performance Indicators (KPIs) to be able to effectively monitor the progress of these PPAs against the stated outcomes. We find the benefits of PPAs to be ambiguous: PPAs generally provide benefits when compared to ‘open’ ocean, however this is not a consistent result. There are no PPAs that provide greater overall benefits when compared to fully protected MPAs. Only one state (South Australia) and the Commonwealth (Australian Marine Parks) are collecting publicly available baseline data to facilitate quantitative monitoring of PPAs. Contrary to fisheries management, there were no plans of action if the declared MPAs and PPAs failed to meet their declared objectives and goals. Some PPAs within Australia appear to be incompatible with conservation priorities according to the recent “MPA Guide” classification framework. This study highlights the need for clearer management rationale and plans for PPAs in Australia, as these comprise the majority of MPAs in Australia’s Exclusive Economic Zone.

Published: January 2025

Background and objectives

Aim of the current study was to assess the perception, preference, and practice of endodontists and restorative dentists at different locations around the world about dental magnification instruments.

Materials and methods

A multicenter, cross-sectional study was ethically approved from the local committee of bioethics. After thorough literature search, a questionnaire was designed and validated. Later, the questionnaire was distributed to 10% (53 participants) of the total planned participants to conduct a pilot study. Based on the feedback from these participants, any ambiguities or discrepancies observed in the items and content of the questionnaire was modified. The questionnaire was assessed for its internal consistency as part of validating the items with Cronbach’s alpha of 0.80. The completed questionnaire with an informed consent form for the participant was administered to the endodontists and restorative dentists in three different geographical regions namely MENA (Middle East and Northern Africa), British-Isles, and Indian Sub-continent using WhatsApp through the snowball convenience sampling technique.

Results

Majority of the participants were male (56.5%) and in the age group of 25–35 years (30.3%). About 68.9% were from Indian sub-continent, followed by the British-Isles (16.5%) and the least (14.6%) were from the MENA region. By large, the participants of the present study, strongly agreed that dental magnification devices improved ergonomics, quality of work, and should be considered as standard of care in modern endodontic. Flip-up magnifiers (51.1%) and medium (8x-16x) magnification were preferred by majority of the participants. About 46.3% of specialist reported that they always used devices for all operative and endodontic procedures, especially while locating hidden and canals and negotiating calcified canals. Participants practicing in British-Isles have 2.42 times (P<0.05) higher adequate perception with reference participants in Indian sub-continent. Additionally, participants with fellowship have 2.77 times more (P<0.01) adequate perception with reference to their counterparts with a master’s degree.

Conclusions

Most of the participants believe that dental magnification devices enhance the prognosis and quality of treatment of possibly all operative and endodontics procedures. Thus, emphasized on the inclusion of devices in the postgraduate curriculum and signifies the role of continuing dental education for specialist and dental assistant handling devices. However, multicenter studies with larger sample is required for generalizing the results.
On escape criterion of an orbit with s−convexity and illustrations of the behavior shifts in Mandelbrot and Julia set fractals

Published: January 2025

Our study presents a novel orbit with s−convexity, for illustration of the behavior shift in the fractals. We provide a theorem to demonstrate the escape criterion for transcendental cosine functions of the type Tα,β(u) = cos(um)+αu + β, for u , α , β ∈ C and m ≥ 2. We also demonstrate the impact of the parameters on the formatted fractals with numerical examples and graphical illustrations using the MATHEMATICA software, algorithm, and colormap. Moreover, we observe that the Julia set appears when we widen the Mandelbrot set at its petal edges, suggesting that each Mandelbrot set point contains a sizable quantity of Julia set picture data. It is commonly known that fractal geometry may capture the complexity of many intricate structures that exist in our surroundings.
Multivariate description of gait changes in a mouse model of peripheral nerve injury and trauma

Published: January 2025

Objective

Animal models of nerve injury are important for studying nerve injury and repair, particularly for interventions that cannot be studied in humans. However, the vast majority of gait analysis in animals has been limited to univariate analysis even though gait data is highly multi-dimensional. As a result, little is known about how various spatiotemporal components of the gait relate to each other in the context of peripheral nerve injury and trauma. We hypothesize that a multivariate characterization of gait will reveal relationships among spatiotemporal components of gait with biological relevance to peripheral nerve injury and trauma. We further hypothesize that legitimate relationships among said components will allow for more accurate classification among distinct gait phenotypes than if attempted with univariate analysis alone.

Methods

DigiGait data was collected of mice across groups representing increasing degrees of damage to the neuromusculoskeletal sequence of gait; that is (a) healthy controls, (b) nerve damage only via total nerve transection + reconnection of the femoral and sciatic nerves, and (c) nerve, muscle, and bone damage via total hind-limb transplantation. Multivariate relationships among the 30+ spatiotemporal measures were evaluated using exploratory factor analysis and forward feature selection to identify the features and latent factors that best described gait phenotypes. The identified features were then used to train classifier models and compared to a model trained with features identified using only univariate analysis.

Results

10–15 features relevant to describing gait in the context of increasing degrees of traumatic peripheral nerve injury were identified. Factor analysis uncovered relationships among the identified features and enabled the extrapolation of a set of latent factors that further described the distinct gait phenotypes. The latent factors tied to biological differences among the groups (e.g. alterations to the anatomical configuration of the limb due to transplantation or aberrant fine motor function due to peripheral nerve injury). Models trained using the identified features generated values that could be used to distinguish among pathophysiological states with high statistical significance (p < .001) and accuracy (>80%) as compared to univariate analysis alone.

Conclusion

This is the first performance evaluation of a multivariate approach to gait analysis and the first demonstration of superior performance as compared to univariate gait analysis in animals. It is also the first study to use multivariate statistics to characterize and distinguish among different gradations of gait deficit in animals. This study contributes a comprehensive, multivariate characterization pipeline for application in the study of any pathologies in which gait is a quantitative translational outcome metric.
Vaccine hesitancy among health paraprofessionals: A mixed methods study
Authors: Hergott Madeline , Andreski Michael , Rovers John
Published: January 2025

Background

The World Health Organization (WHO) defines vaccine hesitancy as “a delay in acceptance or refusal of vaccines despite availability of vaccination services”. Vaccine hesitancy has also been declared a top threat to global health. Some employers imposed vaccine mandates during the Covid-19 pandemic resulting in health care employees resigning or being fired rather than receive a vaccine. Healthcare paraprofessionals such as certified nursing assistants, dietary and home health aides are among the most patient facing of all health care providers. Their beliefs and attitudes about vaccines are critical to how they communicate about vaccines with their patients.

Objective

The objective of this project was to survey health care paraprofessionals to explore their thoughts and opinions about vaccines in general, and Covid-19 vaccines specifically.

Methods

This was a 25 question, mixed methods, cross sectional email survey. Subjects were recruited from the mailing list of a non-profit organization in the Midwest. This organization is dedicated to bringing a face and a voice to healthcare paraprofessionals engaged in direct patient care.

Results

Most respondents were reasonably well informed about vaccines; had received one or more doses of indicated vaccines; used credible resources to learn about vaccines and believed physicians and pharmacists were the most trusted information sources. Qualitative results indicated that respondents expressed support for vaccines but that the support was often qualified in that a respondent may have had both pro and anti-vaccine opinions in the same response. They also expressed that communications about vaccines were often problematic. Additional vaccine-related continuing professional development for healthcare paraprofessionals appears to be indicated.

Conclusions

Although attitudes towards vaccines were generally positive, respondents had concerns about the quality of vaccine information. Additional vaccine-related continuing professional development for healthcare paraprofessionals appears to be indicated.

Published: January 2025

Polycystic ovary syndrome (PCOS) is a primary endocrine disorder affecting premenopausal women involving metabolic dysregulation. We aimed to screen serum biomarkers in PCOS patients using untargeted lipidomics and ensemble machine learning. Serum from PCOS patients and non-PCOS subjects were collected for untargeted lipidomics analysis. Through analyzing the classification of differential lipid metabolites and the association between differential lipid metabolites and clinical indexes, ensemble machine learning, data preprocessing, statistical test pre-screening, ensemble learning method secondary screening, biomarkers verification and evaluation, and diagnostic panel model construction and verification were performed on the data of untargeted lipidomics. Results indicated that different lipid metabolites not only differ between groups but also have close effects on different corresponding clinical indexes. PI (18:0/20:3)-H and PE (18:1p/22:6)-H were identified as candidate biomarkers. Three machine learning models, logistic regression, random forest, and support vector machine, showed that screened biomarkers had better classification ability and effect. In addition, the correlation of candidate biomarkers was low, indicating that the overlap between the selected biomarkers was low, and the combination of panels was more optimized. When the AUC value of the test set of the constructed diagnostic panel model was 0.815, the model’s accuracy in the test set was 0.74, specificity was 0.88, and sensitivity was 0.7. This study demonstrated the applicability and robustness of machine learning algorithms to analyze lipid metabolism data for efficient and reliable biomarker screening. PI (18:0/20:3)-H and PE (18:1p/22:6)-H showed great potential in diagnosing PCOS.
Link prediction of heterogeneous complex networks based on an improved embedding learning algorithm
Authors: Chai Lang , Huang Rui
Published: January 2025

Link prediction in heterogeneous networks is an active research topic in the field of complex network science. Recognizing the limitations of existing methods, which often overlook the varying contributions of different local structures within these networks, this study introduces a novel algorithm named SW-Metapath2vec. This algorithm enhances the embedding learning process by assigning weights to meta-path traces generated through random walks and translates the potential connections between nodes into the cosine similarity of embedded vectors. The study was conducted using multiple real-world and synthetic datasets to validate the proposed algorithm’s performance. The results indicate that SW-Metapath2vec significantly outperforms benchmark algorithms. Notably, the algorithm maintains high predictive performance even when a substantial proportion of network nodes are removed, demonstrating its resilience and potential for practical application in analyzing large-scale heterogeneous networks. These findings contribute to the advancement of link prediction techniques and offer valuable insights and tools for related research areas.

Autocita y mise en abyme
Authors: Kunz Marco
Published: January 2025

La mise en abyme, definida como relación especular entre la obra entera y un fragmento que refleja características importantes de ésta, se basa en un desdoblamiento (o una multiplicación) interno de una parte del texto, una repetición que puede ser figurada o literal. Mientras que la mise en abyme por sustitución metonímica y metafórica ha sido objeto de numerosos estudios, la autocita en cuanto reiteración de pasajes idénticos en la misma obra no ha atraído mucho la atención crítica y su carácter de mise en abyme resulta dudoso en muchos casos. En este artículo se examinan tres textos en que se repiten, con funciones y significados variados y en contextos diferentes, frases o incluso páginas enteras: 1. las variaciones de una conversación telefónica en la pieza teatral Cartas de amor a Stalin de Juan Mayorga; 2. la recreación de ficciones y recuerdos en la novela Remake de Bruno Galindo; 3. la autocita anticipadora del final en El Maestro y Margarita de Mijaíl Bulgákov. El análisis de estas obras permite afirmar que la repetición textual, y no sólo en su forma de autocita con cambio del nivel de enunciación, puede ser una especie de fractal especular que comparte algunas características y funciones con la mise en abyme.
Una membrana creativa: expansión y apropiacionismo en la literatura última de Jorge Carrión
Authors: Pastor Sheila
Published: January 2025

Este artículo estudia la última literatura de Jorge Carrión – el falso diario Lo viral (2020), las novelas Membrana (2021) y Todos los museos son novelas de ciencia ficción (2022), el ciclo de pódcast Solaris (2020-2021) y un corpus de ensayos y artículos de crítica cultural publicados en The New York Times (2019-2021)– como un proyecto de escritura conceptual que hemos denominado «ciclo del siglo XXI». Para ello, en primer lugar se reconstruye la historia textual que conduce a la escritura y difusión de las diferentes obras entre 2019 y 2022, incidiendo en las redes temáticas que se tejen entre ellas. En un segundo momento se analiza el núcleo conceptual del ciclo, la novela Membrana. Finalmente, se examinan las diferentes vías de expansión y las estrategias de apropiacionismo que operan en este entramado creativo. El propósito último es delinear la poética del siglo XXI que ofrece esta membrana creativa, incidiendo en sus relaciones con el arte conceptual y las prácticas curatoriales, el pensamiento contemporáneo y las escrituras subversivas. Desde la intersección de la creación y el pensamiento, en suma, el «ciclo del siglo XXI» plantea una reflexión sobre el presente y el futuro inmediato que nos invita a cuestionarnos qué nos define como humanidad, cómo se definen nuestras ficciones y qué ventura aguarda a ambas.
Apropiacionismo y reciclaje de la noción de traducción en El fill del corrector / Arre, arre, corrector, de Adrià Pujol Cruells y Rubén Martín Giráldez
Authors: Elvira Navarro Andrea
Published: January 2025

Se propone en este artículo el análisis de El fill del corrector / Arre, arre, corrector, de Adrià Pujol Cruells y Rubén Martín Giráldez con el fin de estudiar técnicas apropiacionistas como la reescritura, el ready made o la anotación y su afán por revisar, releer y revalorizar ciertos conceptos desechados por la cultura dominante; esto es, subrayar el afán de reciclaje que entrañan dichos recursos. En concreto, se atenderá a la obra como reflexión acerca del oficio de la traducción en la literatura contemporánea a la que se impone la idea de traducción creativa sostenida hasta el siglo XIX en el circuito editorial. Asimismo, se atenderá a las repercusiones que acarrea el uso del apropiacionismo en el plano paratextual, en la autoría de la obra y en la recepción de la misma para evidenciar el carácter crítico del apropiacionismo en la actualidad.
Reciclando lo propio y lo ajeno. Apropiaciones y desvíos en Las razones de Jo, de Isabel Franc
Authors: Vigna Gaetano Antonio
Published: January 2025

A partir del análisis de las dos ediciones de Las razones de Jo, la primera publicada en el año 2006 y la segunda en 2019, el presente ensayo ofrece una exploración de las operaciones de reciclaje de material narrativo propio y de apropiación de textos ajenos, siendo la novela de Franc la reescritura de Mujercitas. A través de las aludidas prácticas, en el estudio se menciona la superación del axioma romántico de la obra de arte como producto inalterable e irrepetible. De este modo, comenzaremos por apreciar los efectos de la reedición como espacio performativo. Asimismo, poniendo en relación lo social y la estética posmoderna, con su dialéctica de la integración y su tendencia homogeneizadora, comentaremos la labor revisionista de Isabel Franc, quien se sirve de la conocida obra de Louisa May Alcott y crea una historia de amor entre mujeres. El texto, reescrito desde la evidente transformación cultural del mundo contemporáneo y de sus nuevos valores, da voz a la historia silenciada del homoerotismo femenino. El desvío al que se somete el material narrativo deja ver lo relativo de cualquier discurso que se haya tenido por hegemónico.
Kafka apócrifo: fototextualidad y reescritura en Proyecto K. de Paco Gómez
Authors: Venzon Ruben
Published: January 2025

En la última década, el fotógrafo y escritor Paco Gómez (Madrid, 1971) ha destacado en el panorama editorial español por haber publicado varias obras narrativas autoeditadas que, según el paradigma de la fototextualidad literaria, combinan intermedialmente palabra e imagen sobre un mismo soporte libresco. Este artículo se centra en el análisis de Proyecto K. (2016), quizá el libro más singular dentro de su producción, donde el autor no solo reproduce documentos fotográficos auténticos y relata hechos históricos inherentes a la biografía oficial de Franz Kafka, sino que también inserta elementos ficticios tanto icónicos como argumentales. Al mismo tiempo, alrededor de la reconstrucción y la libre reinterpretación de algunas vivencias del escritor checo, Gómez elabora una trama surrealista de investigación fotográfica que lo implica personalmente, otorgando a la narración un marcado carácter metaficcional. En este sentido, el estudio de la presencia de fotografías en diferentes formatos y modalidades, así como de su interacción con el texto, permite determinar la importancia del papel de lo visual en la recepción de esta reescritura apócrifa y cargada de onirismo de la vida de Kafka, reflejo de una obsesión del autor por su existencia y su obra.

(Anti)canon de la investigación de la comunicación en España. Análisis a partir de la visibilidad de sus autores y autoras (1979-1989)
Authors: García-Jiménez Leonarda , Herrero Esperanza
Published: January 2025

La investigación de la comunicación en España desde el punto de vista de sus obras seminales es una cuestión que ha recibido poca atención. Para responder a esta carencia, el presente artículo investiga las obras publicadas en los años 80 desde una perspectiva de género, dado que las mujeres han tendido a ser excluidas del relato epistémico y la historia intelectual de los campos científicos, también del de la comunicación. Para ello, se ha llevado a cabo un análisis de carácter cualitativo, hermenéutico y documental. Se identifican 141 libros de los que solamente 19 (13,4%) están firmados en primer lugar por una mujer. Los libros más citados y que conforman el canon son: El periódico: actor político, La construcción de la noticia y La producción social de comunicación. De manera complementaria, las obras firmadas por mujeres más referenciadas y que constituyen el “anticanon” son: El arquetipo viril protagonista de la historia, Análisis del discurso y La otra política de Aristóteles. Las obras que conforman el canon analizaron la comunicación de masas desde enfoques culturales y teóricos ambiciosos, donde tuvo una especial preponderancia la semiótica. El “anticanon” tuvo igualmente un marcado carácter crítico e impulsó los estudios de comunicación y género en España. Mirar a la producción bibliográfica de los 80 realizada por hombres y mujeres supone recuperar un valioso acervo teórico y crítico y una perspectiva, la semiótica, que tiene hoy poco espacio en una disciplina abocada al empirismo y el artículo científico.

Published: January 2025

El documental Notes sur l’emigration. Espagne 1960 de Jacinto Esteva y Paolo Brunatto es una obra sobre la situación de pobreza y emigración en España en el momento en el que la dictadura estaba iniciando un aperturismo en la década de los años sesenta. Sobre un estudio de caso, empleamos una metodología de análisis textual centrada en la conjunción de varios tipos de documental, la voz narradora, el montaje, el valor de las imágenes, los parámetros contextuales por la repercusión extracinematográfica que tuvo, y la intertextualidad con la obra literaria de Juan Goytisolo, especialmente con Campos de Níjar, que sirvió de inspiración. Partimos de que el documental es una obra militante contra la dictadura y al mismo tiempo fue el punto de partida de un estilo que Esteva desarrollará en el resto de su obra.

Under the Microscope: Media and Mobile Phone Use among Children and Young People in Portugal
Authors: Pereira Sara , Fillol Joana , Brandão Daniel , Menezes-Neumann Mariana
Published: January 2025

Media consumption is heavily influenced by mobile phones and the Internet, especially among younger audiences. Although many studies have demonstrated this, it is essential to continually examine how children's and young people’s relationships with media evolve and affect their lives amid rapid changes in the media ecosystem. Based on an online questionnaire conducted in 26 schools with 1,131 students aged 11 to 19 across Portugal, this study aims to closely examine media usage, particularly mobile phones. By analyzing variables such as school year (corresponding with age) and gender, the research explores mobile phone usage in relation to other media and examines how participants classify themselves as mobile phone users. Findings reveal that children and youth are highly engaged with media, with the mobile phone as the most important device in their lives. The Internet and social networks also rank among the top three most significant media. Time spent on mobile phones increases with school year, correlating with age, and girls use their mobile phones more than boys. More respondents identify as "intensive" or "dependent" users than "moderate" ones. Interestingly, 6th graders (the youngest group) are the most likely to describe themselves as "dependent users." The level of dependency on mobile phones is highlighted by the fact that more than half of the sample would choose their mobile phone as the one object to bring on a long journey.

Redes sociales y hábitos de consumo informativo de los jóvenes españoles: un análisis diacrónico (2021-2023)
Authors: Ceballos-del-Cid Yaiza , Gómez-Calderón Bernardo , Córdoba-Cabús Alba
Published: January 2025

En los últimos años se han registrado cambios de enorme calado en las rutinas informativas de la juventud, sobre todo en cuanto a los canales que esta emplea para acceder a las noticias. El artículo pretende, por un lado, caracterizar el consumo informativo de las personas jóvenes en España y su evolución durante el periodo 2021-2023; y, por otro, definir perfiles diferenciados de usuarios en relación con los contenidos de actualidad. Para ello, se apoya en tres encuestas de carácter anual realizadas a una muestra de 3.999 personas de entre 15 y 24 años, distribuidas proporcionalmente en función del sexo, la edad, el hábitat y la comunidad autónoma. Los resultados permiten extraer varias conclusiones: 1) el interés por las noticias ha aumentado en el periodo de tiempo analizado; 2) las redes sociales se han consolidado como vía prioritaria e incluso única de acceso a la información; 3) la confianza que inspiran los social media sigue por detrás de la de medios tradicionales como la radio o la prensa escrita; 4) el 70% de la gente joven está expuesta a contenidos de actualidad que le llegan de manera incidental; y 5) es posible diferenciar tres grupos de usuarios de entre 15 y 24 años en función de su relación con la información: los que no la buscan y la consumen solo cuando les llega de modo involuntario, los que la buscan pero únicamente a través de los social media, y los que acceden a ella combinando redes y medios de comunicación tradicionales.
Infancias conectadas: el reto de los móviles y pantallas omnipresentes [Editorial]
Authors: Feijoo Beatriz , Fernández-Gómez Erika , Pavez Isabel , Ponte Cristina
Published: January 2025

La presencia de las pantallas en la vida diaria de niños, niñas y adolescentes es un tema recurrente que ha sido abordado desde distintas disciplinas. Es así que las prácticas de acceso y uso a dispositivos móviles han sido estudiadas en tanto su influencia en el desarrollo cognitivo (Putnick et al., 2023; Yang et al., 2024), el rendimiento escolar (Lin et al., 2021; Przepiorka et al., 2021), y dinámicas de mediación parental (Brauchli et al., 2024; Konok, Bunford & Miklósi, 2020) entre otras.  Sin embargo, la movilidad de los dispositivos y constante conectividad (Vorderer & Klimmt, 2020) complejiza este fenómeno invitando a verlo desde múltiples miradas. Es por ello que el presente monográfico es una respuesta a esta necesidad y tiene por objetivo reflexionar, bajo un enfoque multidisciplinar, sobre las tendencias y retos que implica la presencia del teléfono móvil en la vida de los y las menores. Es así que los trabajos que componen este volumen mueven las fronteras al abordar temáticas emergentes como las relaciones de dependencia con los dispositivos, nuevos agentes socializadores como es el caso de los influencers, e incluso aspectos éticos en tanto la protección de derechos de la infancia que a la fecha no han sido abordados. Otra de las riquezas de estos trabajos es la variedad de países en la que se basa la evidencia presentada, dando espacio a trabajos empíricos en distintos contextos sociales y culturales, lo que también avanza el debate.

Lobbies, think tanks y propaganda: ideas y comunicación al servicio del poder [Editorial]
Authors: Pineda-Cachero Antonio , Castillo-Esparcia Antonio
Published: January 2025

Editorial para el monográfico "Lobbies, think tanks y propaganda: ideas y comunicación al servicio del poder".
Las formas para conseguir y/o influir en el poder a través de la comunicación son variadas. La propaganda es uno de los fenómenos comunicativos que, desde la más remota antigüedad (Pizarroso Quintero, 1993), funciona como una herramienta al servicio de los intereses de los poderosos (Pineda Cachero, 2006). Pero la propaganda no es la única forma de comunicación mediante la cual las instancias de poder (político, económico, religioso, etc.) pretenden conseguir sus objetivos estratégicos: instituciones como los lobbies, los think tanks y las organizaciones de advocacy y promoción de valores también lo hacen. Estas instituciones no sólo ejercen su influencia sobre la sociedad y los representantes políticos de forma personalizada, como sucede en el lobbying ejercido directamente sobre los actores políticos por parte de los grupos de interés (Dür y Mateo, 2019). En ocasiones, los objetivos y estrategias de los lobbies pasan por el desarrollo de campañas de movilización de base (Castillo y Almansa, 2020) que pueden contener elementos de comunicación ideológica y política dirigidas a la opinión pública, y con el fin de conseguir, mantener o reforzar una posición de poder. En estos términos, puede hablarse directamente de propaganda, solapándose en ocasiones la comunicación de lobbying con la comunicación política y/o propagandística orientada a la consecución del poder (Doob, 1966). Las campañas ideológicas del poderoso grupo de presión de la Asociación Nacional del Rifle en Estados Unidos serían un ejemplo clásico de ello.
La invasión del algoritmo [Reseña]
Authors: García-Martínez María-Ester
Published: January 2025

La invasión del algoritmo, coordinado por José Antonio Gabelas-Barroso, David García-Marín y Roberto Aparici, es un análisis crítico sobre el impacto y la omnipresencia de los algoritmos en la sociedad actual. A lo largo de seis capítulos, los autores abordan cómo los algoritmos, aunque parecen herramientas neutrales, modifican la conducta humana, afectan las relaciones sociales y establecen nuevas formas de control y manipulación. Nos invitan a reflexionar sobre las intenciones detrás de las plataformas tecnológicas, el monopolio de los datos y los efectos de la personalización de los contenidos. Aunque el libro no es apocalíptico, sí alerta sobre los riesgos de una dependencia tecnológica y la falta de transparencia de los sistemas algorítmicos. La obra propone la necesidad de una alfabetización algorítmica crítica que permita a los individuos comprender y cuestionar el impacto de estos sistemas en nuestras vidas.
