Echokammer extrem? Symbolische Grenzziehungen in der Telegramgruppe von Attila Hildmann
Authors: Becker Annika , Ljajic Amina , Schwarz Simon
Published: July 2021

Basierend auf einer internetethnografischen Untersuchung werden in diesem Beitrag symbolische Grenzziehungen in der Telegramgruppe DEMOKRATENCHAT beziehungsweise FREIHEITS-CHAT dargestellt. Neben unauffälligen Beiträgen ließen sich darin zum Beobachtungszeitpunkt auch extremistische sowie antisemitische Inhalte beobachten und Trollnachrichten ausmachen. Ziel ist es, mithilfe des Konzepts symbolischer Grenzziehungen von Michèle Lamont herauszuarbeiten, wie in der Chatgruppe Grenzziehungen vollzogen werden. Auf dieser Grundlage soll untersucht werden, ob es sich bei derartigen Telegramgruppen um Echokammern handelt: digitale Räume, in denen im Innern vorhandene Meinungen verstärkt werden. Die kommunikativen Praktiken in der Chatgruppe sind chaotisch und jede Nachricht konkurriert mit anderen Beiträgen um Sichtbarkeit. Symbolische Grenzziehungen finden unter anderem als Reaktion auf verschwörungstheoretisch besetzte Buzzwords statt. Der Gründer der Chatgruppe, Attila Hildmann, steht als autoritärer „Agitator“ im Mittelpunkt der kommunikativen Praktiken und ist sowohl Objekt der Ablehnung als auch Identifizierung. Die Studie stellt heraus, dass die Chatgruppe deshalb keine Echokammer ist.
Wundmale der Postdemokratie. Zur gesellschaftlichen Bedingtheit von Verschwörungstheorien in der Pandemie
Authors: Forstenhäusler Robin
Published: July 2021

In der Forschung zu Verschwörungstheorien zeigt sich, dass diese oftmals als ahistorisches Phänomen behandelt werden. Mit Rückgriff auf die Theorie des autoritären Charakters wird dagegen argumentiert, dass Verschwörungsmentalität eine charakterliche Disposition ist, die auf gesellschaftliche Ursachen zurückzuführen ist. Das Individuum muss die Kränkungen und Ohnmachtsgefühle, die es im kapitalistischen Konkurrenzkampf erfährt, durch eine gesteigerte narzisstische Besetzung des eigenen Charakters kompensieren, was vermehrt mithilfe identitätsstiftender Konsumpraktiken und der öffentlichen Performanz von Authentizität geschieht. Aktuell fallen aufgrund der Einschränkungen im Zuge der Covid-19-Pandemie die Möglichkeiten dazu weg. Verschwörungstheorien stellen ein Mittel dar, diesen triebökonomischen Mangel auszugleichen.

Authors: Iosifescu Oana , Licht Christian
Published: July 2021

By using a nonlinear version of Trotter’s theory of approximation of semi-groups acting on variable Hilbert spaces, we propose an asymptotic modeling for the behavior of a linearly elastic plate in bilateral contact with a rigid body along part of its lateral boundary with Norton or Tresca friction.
Linear theory for a mixed operator with Neumann conditions
Authors: Dipierro Serena , Proietti Lippi Edoardo , Valdinoci Enrico
Published: July 2021

We consider here a new type of mixed local and nonlocal equation under suitable Neumann conditions. We discuss the spectral properties associated to a weighted eigenvalue problem and present a global bound for subsolutions.

The Neumann condition that we take into account comprises, as a particular case, the one that has been recently introduced in ( Rev. Mat. Iberoam. 33(2) (2017), 377–416).

Also, the results that we present here find a natural application to a logistic equation motivated by biological problems that has been recently considered in (Dipierro, Proietti Lippi and Valdinoci (2021)).

Published: July 2021

Background: The amyloid-β oligomers, consisting of 10–20 monomers (AβO10–20), have strong neurotoxicity and are associated with cognitive impairment in Alzheimer’s disease (AD). However, their role in patients with idiopathic normal pressure hydrocephalus (iNPH) is poorly understood. Objective: We hypothesized that cerebrospinal fluid (CSF) AβO10–20 accumulates in patients with iNPH, and its clearance after CSF shunting contributes to neurological improvement. We measured CSF AβO10–20 levels before and after CSF shunting in iNPH patients evaluating their diagnostic and prognostic role. Methods: We evaluated two iNPH cohorts: “evaluation” (cohort-1) with 32 patients and “validation” (cohort-2) with 13 patients. Comparison cohorts included: 27 neurologically healthy controls (HCs), and 16 AD, 15 Parkinson’s disease (PD), and 14 progressive supranuclear palsy (PSP) patients. We assessed for all cohorts CSF AβO10–20 levels and their comprehensive clinical data. iNPH cohort-1 pre-shunting data were compared with those of comparison cohorts, using cohort-2 for validation. Next, we compared cohort-1’s clinical and CSF data: 1) before and after CSF shunting, and 2) increased versus decreased AβO10–20 levels at baseline, 1 and 3 years after shunting. Results: Cohort-1 had higher CSF AβO10–20 levels than the HCs, PD, and PSP cohorts. This result was validated with data from cohort-2. CSF AβO10–20 levels differentiated cohort-1 from the PD and PSP groups, with an area under receiver operating characteristic curve of 0.94. AβO10–20 levels in cohort-1 decreased after CSF shunting. Patients with AβO10–20 decrease showed better cognitive outcome than those without. Conclusion: AβO10–20 accumulates in patients with iNPH and is eliminated by CSF shunting. AβO10–20 can be an applicable diagnostic and prognostic biomarker.

Authors: Palermo Giovanni , Giannoni Sara , Giuntini Martina , Belli Elisabetta , Frosini Daniela , Siciliano Gabriele , Ceravolo Roberto
Published: July 2021

Background: It has been speculated that stains are neuroprotective and are associated with a reduced risk of Parkinson’s disease (PD), but only a few studies have investigated the influence of statins on the progression of PD. Objective: To evaluate whether long-term statin use may affect motor progression in a large cohort of de novo patients with PD. Methods: We conducted a 4-year retrospective observational cohort study to assess patients with PD. The patients were consecutively recruited from a single tertiary center between January 2015 and January 2017. Information on motor function was obtained using the MDS-Unified Parkinson Disease Rating Scale (UPDRS)-III and all subjects were extensively characterized, including information about lifestyle habits, cardiovascular risk factors and cholesterol blood levels. Results: Of the 181 participants included in the study, 104 patients were evaluated for eligibility (42 patients were exposed to statin therapies and 62 were not treated with statins). They presented similar scores in UPDRS III at baseline but the statin users had a lower motor impairment at 4 years compared to non-user PD patients. Additionally, statin treatment resulted in slower progression of the rigidity score of UPDRS over 4 years. No other significant differences were observed between PD patients with and without statins. Conclusion: Early PD patients with long-term statin usage showed lower motor deterioration after 4 years of disease duration compared with patients not taking statins at diagnosis, suggesting a possible influence of statins on disease progression in PD. Further investigation is warranted to understand the potential beneficial effects of statin treatment on clinical symptoms in PD.

PURPOSE: The purpose of this study was to examine the psychometric properties of the Pediatric Evaluation of Disability Inventory-Computer Adaptive Test (PEDI-CAT) in children and youth with Spinal Muscular Atrophy (SMA). METHODS: In this prospective cross-sectional study, caregivers of children and youth with SMA completed the PEDI-CAT Daily Activities and Mobility domains. A subset of caregivers completed a questionnaire about the measure. RESULTS: Mean ranks of scaled scores for Daily Activities (n = 96) and Mobility (n = 95) domains were significantly different across the three SMA types and across the three motor classifications. Normative scores indicated that 85 participants (89.5%) had limitations in Mobility and 51 in Daily Activities (53.1%). Floor effects were observed in≤10.4% of the sample for Daily Activities and Mobility. On average, caregivers completed the Mobility domain in 5.4 minutes and the Daily Activities domain in 3.3 minutes. Most caregivers reported that they provided meaningful information (92.1%), were willing to use the PEDI-CAT format again (79%), and suggested adding content including power wheelchair mobility items. CONCLUSION: Convergent validity was demonstrated for the Daily Activities and Mobility domains. Normative scores detected limitations in Mobility and Daily Activity performance for most participants with SMA. The PEDI-CATwas feasible to administer and caregivers expressed willingness to complete the PEDI-CAT in the future.
Review of auto-ID technology use in warehouse management
Authors: Hassan Mayadah , Piramuthu Selwyn
Published: July 2021

Warehouses play a significant role in the seamless distribution, integration, and storage of items as well as in supply chain operations. Automated identification (auto-ID) technologies that include barcode and RFID provide class- or item-level visibility to facilitate effective and efficient decisions in their respective environments. A warehouse environment benefits from auto-ID through improved cost savings, operational efficiency, and opportunities for higher revenues. It is therefore not surprising that both researchers and practitioners have considered the use of auto-ID in warehouses. We take stock of related literature to determine the state-of-the-art on auto-ID use in warehouse management, with specific focus on RFID, and identify potential directions of further research. Based on our review, we develop a conceptual framework that incorporates the primary factors that guide the decision to adopt auto-ID in warehouse management.

Some aspects of consideration of initial imperfections in the calculations of stability of thin-walled elements of open profile
Authors: Okhten Ivan , Lukianchenko Olha
Published: July 2021

Performed analysis of the initial geometric imperfections influence on the stability of the open C-shaped bars. Test tasks were solved in MSC Nastran, which is based on the finite element method. Imperfections are given in different formulations: the general stability loss of an ideal bar, of wavy bulging of walls and shelves, of deplanation of a bar. To model imperfections, has been developed a program which for the formation of new coordinates of the nodes of the "deformed" model, the components of a vector similar to the form of stability loss are added to the corresponding coordinates of the middle surface of the bar. In this way, you can set initial imperfections in the forms of stability loss of the bar with different amplitude. Researches made with different values of the imperfection amplitude and eccentricity of applied efforts. All tasks are performed in linear and nonlinear staging. The conclusion is made regarding the influence of initial imperfections form and imperfection amplitude on the critical force in nonlinear calculations. It was found that the most affected are imperfections, which are given in the form of total loss of stability. It was revealed the influence of the imperfection amplitude on the magnitude of the critical force for such imperfections. The influence of imperfections amplitude given in the form of wavy bulging walls and in the form of deplanations is not affected on the value of the critical force.

Published: July 2021

Se encontró que la precisión de la estimación del volumen de órganos internos realizada con ultrasonido (EE. UU.) Es multifactorial. Por lo tanto, nuestro objetivo fue describir y validar la evaluación de volumen de la ecografía y las fórmulas estándar de estimación de volumen para órganos intraabdominales de diferentes formas utilizando bazos y riñones.
Se escanearon riñones cadavéricos disecados (n = 25) y bazos (n = 29) para obtener medidas lineales y volúmenes autogenerados por ultrasonido (USV). Se utilizaron medidas lineales para calcular los volúmenes manualmente con fórmulas de estimación de volumen elipsoide, prolate y Lambert. Los volúmenes reales (AV) de los órganos se obtuvieron mediante el método de desplazamiento de agua. Se comparó la precisión de la evaluación del volumen de USV y diferentes fórmulas comparando el sesgo, la precisión y el análisis de la gráfica de Bland-Altman. El procedimiento de medición de volumen y lineal de EE. UU. Fue confiable con acuerdos altos entre observadores e intraobservadores (lineal: α de Chronbach = 0,983 a 0,934; volúmenes: α de Chronbach = 0,989). Las estimaciones de USV fueron precisas con una alta correlación con AV y un bajo sesgo de estimación (-5,9%). Además, las fórmulas prolate (sesgo = -0,75%) y elipsoide (sesgo = -3. 75%) fueron confiables con un sesgo insignificante en los volúmenes estimados. Por el contrario, la fórmula de Lambert no fue confiable debido a un alto sesgo (41,6%). Para todos los métodos evaluados, el error de estimación se encontró relacionado con el tamaño del órgano (T = 3.483; p = 0.001), principalmente cuando el órgano evaluado es mayor de 50 ml. Además, se encontró que el error de estimación de forma está relacionado con la fórmula de estimación de volumen usado. la fórmula de Lambert no fue confiable debido a un alto sesgo (41,6%). Para todos los métodos evaluados, el error de estimación se encontró relacionado con el tamaño del órgano (T = 3.483; p = 0.001), principalmente cuando el órgano evaluado es mayor de 50 ml.

Correlation of Breakfast Consumption Frequency and Grade Point Average in Preclinical Medical Students
Authors: Thuma Tobin , Lawandy Marco , Lomiguen Christine
Published: July 2021

Background:

Due to its nutritious, metabolic, and overall energy-providing benefits, studies have emphasized the value of breakfast, resulting in support of breakfast as “the most important meal of the day,” and subsequently, essential for academic success. However, limited research exists on the impact of habitual breakfast consumption on medical students. How does eating breakfast contribute to the academic success and well-being of medical students?

Methods:

A voluntary survey was distributed to preclinical medical students to gather information on their breakfast-eating habits as well as other indicators of well-being, including mental health, physical health, and stress. Participants indicated the average number of times per week they consumed breakfast. They also recorded the likelihood of eating breakfast on the day of an exam and various components of well-being on a five-point Likert scale. Subjects also provided student identification (ID) numbers. To measure academic success, grade point averages (GPAs) were then extracted using each student's ID number. A correlation analysis was performed between the breakfast-eating habits of medical students and their GPA.

Results:

121 surveys met the inclusion criteria. A correlation analysis showed that frequency of eating breakfast was positively correlated with GPA (r=0.35, p<0.001). Eating breakfast on the day of an exam was also positively correlated with GPA (r=0.32, p<0.001). Eating breakfast had no significant correlation with indices of well-being.

Conclusion:

Consistently eating breakfast may contribute to greater academic performance among medical students. However, eating breakfast appears to have no impact on well-being. Based on this research, eating breakfast regularly may help preclinical medical students boost their academic performance.
Root cause analysis of cationic polymer additive efficiency decline in virgin and recycle containerboard mills
Authors: SHAROYAN DAVIT E. , ROSS CORY W.
Published: July 2021

It is well known that retention, drainage and strength polymers struggle to perform (if at all) in virgin containerboard mills. In-depth studies have been undertaken in this area for more than seven years, investigating the issue from all directions.
A key finding of this work is that soluble lignin is detrimental to chemical efficiency. A strong correlation exists between decreased chemical efficiency and high soluble lignin. Both recycled systems and virgin systems have been studied, and this correlation holds true regardless of furnish. The primary area of concern is virgin container-board, because these mills tend to have the highest lignin levels. Some highly closed recycled mills can also build elevated lignin levels that can negatively affect chemical efficiency.
Wheat straw as an alternative pulp fiber
Authors: HART PETER W.
Published: July 2021

The desire to market sustainable packaging materials has led to an interest in the use of various fiber types as a raw material. It has been suggested that the use of annual crops for partial replacement of wood fiber would result in more sustainable products. Several life cycle analyses (LCA) have been performed to evaluate these claims. These LCAs provided conflicting and contradictory results because of the local conditions and the spe-cific pulping processes investigated. Selected LCAs are reviewed and the underlying reasons for these conflicting results are analyzed. Of all the agriculturally sourced annual fibers available, other than wood, only straw pulp is currently available in commercial quantities. A careful review of the available data suggests that neither an annual crop nor wood are more sustainable in general. Countries that allow burning of straw after harvest present a unique situation. Each situation needs specific and direct comparisons that are not generally available. The use of straw fiber in place of wood fiber does not appear to present any advantages to either the environmental impact of production or to the final product quality. The impact of substitution of straw fiber for hardwood pulp in bleached board applications and for high yield pine in linerboard applications has been examined in handsheet studies. In general, the partial substitution of straw pulp for wood pulp does not improve the handsheet physical properties. These studies suggest that straw pulp should be used in low fiber strength requirement applications, such as tissue and molded fiber products. Commercial progress of straw pulping by Kimberly-Clark and Essity in low fiber strength requirement applications is a sign that the nonwood fiber opportunity has growth potential.
Alternative “green” lime kiln fuels: Part II—Woody biomass, bio-oils, gasification, and hydrogen
Authors: HART PETER W.
Published: July 2021

This paper is the second of a two-part series on “green” lime kiln fuels. The first part of this work reviews the use of pulp mill and recovery byproducts as either full or partial replacement of oil or natural gas in the kiln. The second part reviews the use of various forms of woody biomass, bio-oils, gasification and hydrogen as potential carbon neutral or carbon-free lime kiln fuels. Several of these options require specialized burners to supply the fuel to the kiln and high-quality metallurgy to withstand the acidic conditions of the fuel.
Cationic emulsions of maleic anhydride derivatives of oleic acid and abietic acid for hydrophobic sizing of paper
Authors: HUBBE MARTIN A. , PAL LOKENDRA , BILDIK DAL AHSEN EZEL
Published: July 2021

Ordinary rosin sizing agents are mixtures of resin acids that include abietic acid and related com-pounds obtained from softwoods such as pine. Fatty acids, which are another byproduct of the kraft pulping of soft-wood species, also may have hydrophobic effects, but their use as sizing agents has seldom been considered.
In the current study, abietic acid and oleic acid, in the absence of other components, were first modified by reaction with maleic acid anhydride. Then, the maleated derivatives (maleated oleic acid [MOA] and maleated abietic acid [MAA]), which were emulsified with cationic starch at the 1:1 and 3:2 ratio, respectively, were added to fiber furnish containing aluminum sulfate (papermaker’s alum). The prepared sheets were dried with a rotating drum on one side at 100°C at low pressure to cure the sizing agents. The chemical, optical strength, and absorption properties were measured. The presence of the sizing material was confirmed using time of flight secondary ion mass spectrometry (ToF-SIMS), and the retention of the sizing agent on fibers was supported by evidence of hydrocarbons on the paper surface.
In addition to achieving sufficient water resistance features with MAA, a lesser hydrophobic character was obtained when using MOA. Compared to commercial applications, relatively large amounts of sizing agent were used to obtain a sufficient sizing degree. The MOA required 5% addition to achieve a similar sizing degree as MAA at the 2% level. The sizing treatments also resulted in substantial increases in tensile index value. Since cationic starch was used in the formulation of the sizing agents, the increase in tensile index may have been due to the influence of cationic starch. Contributions to paper strength from a combination of ionic complexation and mutual association of hydrophobic groups is also proposed. Depending on the amount of sizing agent, the yellowness increased, especial-ly when sizing with MOA.
EFFECT OF MALARIA INFECTION ON HEPATIC AND RENAL FUNCTIONS IN PREGNANT WOMEN ATTENDING ANTENATAL CLINIC AT GENERAL HOSPITAL DUTSE, JIGAWA-NIGERIA
Authors: Balogun J. B. , Muhammad Shamsiyya Sani , Dogara Musa Mustapha
Published: July 2021

The effect of malaria infection on hepatic and renal functions in pregnancywas investigated. Three malarious and non-malarious pregnant women  of age ranges 15 to 40 years with a mean (SD) of 23.5 (6.6) years and a median (IQR) of 20.5 (18.3 to 27) years were enrolled. Liver enzymes (AST, ALT and ALP) and Kidney (UCE) functions were determined using Randox standard assay kits. The levels of alkaline phosphatase (ALP) and albumin were significant as malaria infected pregnant women had significantly lowered levels of ALP and albumin compared to controls (21.3 vs 26.1 IU/L, P = 0.03 and 4.8 vs 6.0 g/dl P = 0.02). There was no significant difference between malaria infected pregnant women and their non-malarious counterparts (P > 0.05) in their renal functions. There was no significant difference in mean concentrations of urea, creatinine, sodium, potassium and chloride  regardless of the severity of malaria. Usually in pregnancy markers of liver function decrease due to expansion of extracellular fluid except alkaline phosphatase which is elevated due to its placental origin. Results of this study showed decreased level of ALP  which could possibly be an indication that the parasite has not reached its hepatic stage. The severity of gestational malaria depends on the initial immunity of the pregnant woman. The impact of malaria on pregnancy and conversely, the impact of pregnancy on malaria, are two factors which must be put into consideration during gestational malaria

Published: July 2021

We report herein an economically cheap and functionally stable surfaceenhanced Raman scattering (SERS) protocol of two photoactive pigments Rhodamine 6G (R6G) and Kiton Red (KR), implemented in thin films of silver (Ag) and gold (Au) nanoparticles (AgNPs and AuNPs). Both commercially available and chemically synthesized nanoparticles were used. The suitability of the nanoparticles toward SERS activity was tested through UV-visible absorption spectroscopy and scanning electron microscopy (SEM). The AgNPs and AuNPs based SERS substrates in the form of films were fabricated onto square-sized aluminum(Al) plates by simple drop deposition of colloidal nanoparticles solution onto their polished surfaces. The prepared nanoparticle films were sufficiently dried and coated further with the probe (R6G and KR) molecules by employing the identical deposition technique. The enhanced Raman signals of R6G and KR in such composite film structures were then recorded through a custom-built dispersive Raman spectrometer with He-Ne laser excitation at 632.8 nm. Our AgNPsfilm-based SERS protocol could yield the magnitude of the Raman signal enhancement up to 104 times for both R6G and KR. Moreover, AuNPs-based film was found to be less efficient toward the Raman enhancement of both compounds. Our SERS substrates can be easily fabricated, and SERS spectra are reproducible and stable, allowing one to consistently get a reproducible result even after 6 months.

Published: July 2021

Background: Volunteering among nursing students has become a valuable resource during an outbreak to help alleviate the strain in nursing staff shortages. However, evidence of willingness to volunteer is scarce, particularly in Asian countries.Objective: To study Bruneian university nursing students’ willingness to volunteer during a pandemic in Brunei. Methods: An online cross-sectional study was conducted at Universiti Brunei Darussalam from January to February 2021. A self-administered questionnaire was used to measure willingness factors, including motivational factors, barriers, enablers, and level of agreement to volunteer during the COVID-19 pandemic. Sub-group inferential analysis was applied. Results: 72 participants were included in this study. 75.0% of whom were willing to volunteer during the COVID-19 pandemic. Factors that influenced the willingness of nursing students to volunteer were marital status (p <0.001), year of study (p <0.001), altruism (p <0.001), personal safety (p <0.001), and knowledge level (p <0.001). Conclusion: Nursing students are an invaluable resource, and they are highly willing to be part of disaster management. Training and planning should prepare the nursing students for disaster or pandemic readiness and integrated them into the undergraduate nursing curriculum. Align with this, safety aspects of nursing students during volunteering should also be considered, including the provision of childcare assistance, sufficient personal protective equipment, vaccination, and prophylaxis to the volunteers.

Authors: Tanioka Tetsuya , Betriana Feni , Yokotani Tomoya , Osaka Kyoko , Locsin Rozzano C. , King Beth , Schoenhofer Savina
Published: July 2021

Background: Caring expressions between humans and nonhuman intelligent machines are futuristic prototypes with healthcare robots as major advocates. 
Objective: To examine the experience of older persons with mental health conditions, particularly patients with schizophrenia and with dementia in the interaction with healthcare robots and intermediaries in a transactive relational engagement.
Methods: Two qualitative case studies were conducted using sophisticated audio-video technologies to record the conversation and activities that were carefully documented. Following the procedure for qualitative descriptive analysis, a framework based on the Transactive Relationship Theory of Nursing was employed to analyze and interpret the data. 
Results: Three themes were revealed, including feelings for the other, inspiring meaningful responses, and demonstrating expressions of joy. The description of the experience of older persons involved in the conversation with humanoid robots was feeling for the other while inspiring meaningful responses in demonstrating expressions of joy. 
Conclusion: This study provided initial evidence that the transactive engagements of robots with older persons with schizophrenia and dementia and nurse intermediaries in psychiatric and mental health settings can result in occasions of ‘joy’ for the patients. These findings suggest that transactive engagements with robots facilitate expressions of joy among older persons with schizophrenia and dementia. However, these findings are not intended to prescribe nursing care actions but to describe the experience of older persons who are in transactive engagements with intelligent machines, indicating the importance and value of healthcare robots in nursing older persons with schizophrenia and with dementia.

Contenidos eficientes en redes sociales: la promoción de series de Netflix
Authors: Navío Navarro Mariché
Published: July 2021

Los canales de redes sociales son frecuentemente utilizados por distintos productos audiovisuales a la hora de promocionar los contenidos y generar conversaciones alrededor de sus marcas. En el caso de las series de ficción emitidas por Netflix, los medios sociales de mayor uso son Instagram, Facebook y Twitter. Esta investigación tiene como objetivo establecer cuáles son las características del contenido que, publicado en los perfiles de estas tres plataformas por parte de las cuentas de estas series de ficción, generan una mayor eficiencia y efecto viral. Para ello, analizamos las ocho publicaciones con mayor número de interacciones totales en una muestra de perfiles de series para determinar qué plataforma, formatos, tipos de contenido, hashtags, emojis o valores apelados, entre otros factores, obtienen mejores resultados en cuanto a los distintos tipos de interacción: «me gustas», comentarios y compartidos. Los principales resultados apuntan a Instagram como la red social más eficiente, donde las imágenes son el contenido con mayor número de interacciones. En Facebook y Twitter, sin embargo, los vídeos consiguen la mayor eficiencia y viralidad. Para el resto de las categorías de análisis, encontraremos diferencias entre las tres plataformas.
El estilo retórico femenino en la entrevista política. Una década de aplicación en Telva
Authors: Quevedo Redondo Raquel
Published: July 2021

Esta investigación pretende comprobar cómo las características del llamado ‘estilo retórico femenino’ condicionan la manera en que líderes y lideresas se dirigen a la ciudadanía. Se parte de la premisa de que los rasgos del feminine style se acentúan cuando la audiencia está conformada por una mayoría de mujeres, por lo que se toman como referencia 25 entrevistas a políticos publicadas en la revista femenina Telva, por tratarse de la cabecera española que más contenidos de este tipo ha albergado en la última década (2011-2020). El análisis de contenido permite comprobar que tanto varones como féminas ponen en práctica estrategias que potencian el mayor y mejor tratamiento de women´s issues y soft politics en su discurso (feminización de la agenda), además de recurrir a la estructura inductiva, las apelaciones al conjunto, el uso de palabras con connotaciones emocionales y el encomio de la ética del cuidado.

Authors: Ballesteros Herencia Carlos Antonio
Published: July 2021

Los clubes de fútbol se han incorporado rápidamente a los sucesivos avances en las tecnologías de la información, entre ellos, las redes sociales, donde ocupan posiciones destacadas de audiencia. La generación de vínculos de compromiso con los seguidores se ha señalado como una vía para alcanzar los objetivos de las organizaciones deportivas. Esta investigación se propuso describir el uso de Facebook, Instagram y Twitter por parte de los clubes españoles de fútbol de la Primera División de la Liga de Fútbol Profesional (LFP) en cuanto a la frecuencia de publicación de mensajes, número de seguidores online e intensidad de la implicación de los usuarios de las redes sociales. Se analizaron estadísticamente 6.000 mensajes, capturados automática y manualmente. Se halló una frecuencia diaria de publicación promedio de 31 mensajes por club entre las tres redes, siendo Twitter la plataforma de mayor frecuencia de publicación. En cambio, la red con más seguidores fue Facebook, mientras Instagram lideró tanto el número de interacciones como la intensidad del índice de engagement. Además, se detectó correlación entre factores online como el número de seguidores o de interacciones y factores offline que describían el tamaño del club.

La presente investigación pretende dilucidar cuál es el peso que ostentan las grandes marcas de ropa deportiva en cuanto a patrocinios dentro del futbol profesional europeo de élite. Se determinará además si Adidas y Nike tienen un protagonismo parejo en cuanto a su capacidad de activación de patrocinios dentro de este sector, clave en su batalla global por ser líderes del mercado en el que compiten. Para obtener información relevante al respecto se pone en marcha una primera etapa destina a construir un marco teórico a través del uso de la revisión bibliográfica y documental. La segunda etapa desarrolla una investigación ‘ad hoc’ que utiliza el análisis de contenido para registrar a los principales agentes del sector del futbol europeo de élite, y cuáles son sus patrocinadores oficiales de ropa deportiva. Los resultados obtenidos indican que Adidas y Nike dominan claramente la activación de este tipo de patrocinios. Nike es la marca hegemónica sobre la activación de patrocinios individuales de futbolistas, mientras que en los patrocinios colectivos de clubes y federaciones destaca discretamente Adidas. Se puede concluir que no existe un peso exactamente equilibrado entre los logros de activación de patrocinios conseguidos por ambas marcas.
