Authors: Grau-Alberola Ester , Figueiredo-Ferraz Hugo , López-Vílchez Jorge Jesús , Gil-Monte Pedro R.
Published: January 2022

Psychosocial risks arising from work, like workload, have a negative impact on the quality of work life, especially in terms of the deterioration in working conditions and negative consequences for employees’ health. The style of leadership exercised is key in coping with perceived psychosocial risks. The purpose of this study was to analyse the influence of transformational leadership and workload on psychosomatic disorders, and the moderating role of transformational leadership in the relationship between workload and psychosomatic disorders. The sample consisted of 408 Spanish employees working with people with intellectual disabilities. Workload and Psychosomatic disorders were measured by the UNIPSICO subscales, Transformational leadership was measured by a subscale adapted from the Multifactor Leadership Questionnaire (Bass & Avolio, 1989). Carrying out moderation analysis in PROCESS 3.4 results showed that both Workload and Transformational leadership had a significant influence on Psychosomatic disorders. In addition, Transformational leadership moderated the relationship between Workload and Psychosomatic disorders. Transformational leadership buffers the impact of workload on employees’ health and therefore in the need to carry out training programs for managers in organizations in order to exercise a healthy management.

Los riesgos psicosociales derivados del trabajo, como la sobrecarga laboral, tienen un impacto negativo en la calidad de vida laboral, especialmente en el deterioro de las condiciones laborales y en la salud de los empleados. El estilo de liderazgo ejercido es clave en el afrontamiento de los riesgos psicosociales percibidos. El propósito de este estudio fue analizar la influencia del liderazgo transformacional y la sobrecarga laboral sobre los problemas psicosomáticos, y el papel moderador del liderazgo transformacional en la relación entre sobrecarga laboral y problemas psicosomáticos. La muestra consistió en 408 empleados españoles que trabajan con personas con discapacidad intelectual. Sobrecarga laboral y Problemas psicosomáticos se midieron con las subescalas UNIPSICO y Liderazgo transformacional se midió con una subescala adaptada del Cuestionario Multifactorial de Liderazgo (Bass & Avolio, 1989). El análisis de moderación mediante PROCESS 3.4 mostró que tanto Sobrecarga laboral como Liderazgo transformacional tuvieron una influencia significativa sobre Problemas psicosomáticos. Además, Liderazgo transformacional moderó la relación entre Sobrecarga laboral y Problemas psicosomáticos. El liderazgo transformacional amortigua el impacto de la sobrecarga laboral en la salud de los empleados y, por lo tanto, se destaca la necesidad de implementar programas de capacitación para directivos en las organizaciones con el fin de ejercer una gestión saludable.

La salud mental positiva es un constructo complejo que está relacionado con el funcionamiento óptimo de la persona. Comprende un conjunto de cualidades orientadas al desarrollo del potencial del individuo. La Escala de Salud Mental Positiva es uno de los instrumentos más utilizados para evaluarlo, sin embargo, los antecedentes señalan inconsistencias respecto a su estructura interna. El objetivo del presente estudio fue analizar las propiedades psicométricas de la Escala de Salud Mental Positiva en Arequipa-Perú. Participaron 3933 personas, 50.3% fueron mujeres y 49.7% fueron varones, incluyendo desde adolescentes hasta adultos mayores. La evaluación mediante AFC de la estructura original evidenció índices de ajuste pobres, por lo que se tuvo que evaluar la dimensionalidad y proponer una nueva estructura. Para lo cual, se dividió a la muestra (n1 = 1966 y n2 = 1967). En la primera, se aplicó un AFE y en la segunda se valida mediante un AFC. Se hallaron tres factores y se concluye que tiene un buen ajuste (χ2(431) = 2473.378; CFI = .959; TLI = .956, RMSEA = .049; SRMR = .051). La consistencia interna mostró valores mayores a .81. Finalmente, se evaluó la equivalencia de la medición según el sexo, hallando que el instrumento presenta invarianza de la medición.

Authors: Kokun Oleg , Pischko Iryna , Lozinska Natalia
Published: January 2022

Examining military personnel’s psychological states is an effective way to prevent negative mental health consequences during their deployment in a war zone. The present study identifies changes in the psychological states of military personnel (n = 192) during a 6-month deployment in a war zone in eastern Ukraine. The results confirmed both of our proposed hypotheses. First, with regard to time limits on military personnel’s deployment on the front lines in eastern Ukraine on the basis of examined psychological states, the estimated recommended deployment duration was three months. Second, we found significant differences in the dynamics of the psychological states of service members with versus without previous deployment experience. The results also substantiate that military personnel’s psychological states should be monitored during deployment in order to prevent negative mental health consequences and to ensure that military units successfully accomplish their tasks.

Una de las formas más eficaces para prevenir las consecuencias negativas del despliegue en la zona militar para la salud mental de los militares es diagnosticar su estado psicológico. En el presente estudio se determinan las particularidades de los cambios en el estado psicológico de los militares (n = 192) durante el despliegue de seis meses en la zona militar en el este de Ucrania. Los resultados obtenidos confirmaron ambas hipótesis formuladas: en cuanto a la posibilidad de determinar, sobre la base del diagnóstico del estado psicológico, el plazo recomendado para el despliegue de los militares en la línea de demarcación en el este de Ucrania, que es de tres meses. Así como también sobre las posibles diferencias significativas en la dinámica del estado psicológico de los militares que tienen y no tienen experiencia en el despliegue. Asimismo, se argumenta la necesidad de monitorear el estado psicológico de los militares durante el despliegue con el propósito de prevenir oportunamente las consecuencias negativas para su salud mental y para la ejecución exitosa de las tareas de la subunidad militar.
Refugee Policies and Narratives in the Globalised Era
Authors: Herrero Dolores
Published: January 2022

One of the effects of globalisation has been population mobility as a result of famine, climate warming and war conflicts, among other things. This flow of refugees, however, is often seen as a menace to the rule of law and human rights concomitant with the Western lifestyle. Refugees are no longer regarded as human beings and victims, but rather as danger, even as potential terrorists, which has led many governments, including the Australian, to detain them indefinitely in detention centres where they are confined in inhuman conditions. The main aim of this paper will be to describe Australian immigration policies and how contemporary Australian narratives on and by refugees are reflecting this situation, mainly by analysing a selection of texts from three recently published collections, namely, A Country Too Far (2013), They Cannot Take the Sky (2017) and Seabirds Crying in the Harbour Dark (2017), and Behrouz Boochani’s No Friend but the Mountains (2018).
Are EFL Writers Motivated or Demotivated by Model Texts and Task Repetition? Evidence from Young Collaborative Writers
Authors: Lázaro-Ibarrola Amparo , Villarreal Izaskun
Published: January 2022

Studies on multi-stage writing tasks with adults and children have shown that model texts and task repetition aid language acquisition, especially when learners work in collaboration. However, these studies have not included measures of task motivation, which is vital in young learners (YLs) and could help develop a more comprehensive understanding of task effectiveness. The present study analyses task motivation in 24 EFL YLs writing in pairs during three sessions divided into a model group (MG) and a task repetition group (TRG). Results show that students’ task motivation is high in general but declines in the MG while it is maintained in the TRG. As for the motives, working together is the main reason students give to justify their positive scores. These results complete previous knowledge about models and TR, reinforce the value of collaborative writing and encourage the inclusion of motivation measures in task-based research.
Materializing
Authors: Andelsman Victoria
Published: January 2022

The present article explores how cycles are brought into being through the practices and affordances involved in period-tracking with apps. Based on thirteen in-depth semi-structured interviews with period-tracking app users living in the Netherlands, it expands on literature discussing the relationship between embodiment, apps, and quantification. The contributions of this article are two-fold. Theoretically, it argues for the use of Karen Barad’s notion of apparatus to understand how bodies are (re)configured in relation to self-tracking technologies (1998). Empirically, it exposes how bodies emerge in localized period-tracking practices, within material-semiotic arrangements that both resist and reproduce cultural ideals about menstruating bodies. Period-tracking with apps, this study finds, brings the body’s interior processes into being in a “systematic” way, (re)configuring the cycle as either a series of phases or an interval with a certain (normative) duration. In all cases, periodtracking with apps becomes a means for users to access their internal body and to materialize the invisible processes of the cycle in ways that can be acted upon.
Collective, unruly, and becoming
Authors: Stenström Kristina , Winter Katarina
Published: January 2022

Online contexts offer an important source of information and emotional support for those facing involuntary childlessness. This article reports the results from an ethnographic exploration of TTC (trying-to-conceive) communication on Instagram. Through a new materialist approach that pays attention to the web of intraacting agencies in online communication, this article explores the question of what material-discursive bodies (constructs of embodiment and medical information) emerge in TTC communication as the result of shared images and narratives of bodies, symptoms, fertility treatments, and reproductive technologies. Drawing on a lengthy ethnographic immersion, observations of 394 Instagram accounts, and the close analysis of 100 posts, the study found that TTC communication produces collective, unruly, and becoming bodies. Collective bodies reflect collectively acquired, solidified, and contested medical knowledge and bodies produced in TTC communication. Unruly bodies are bodies that do not conform to standard medical narratives. Becoming bodies are marked by their shifting agency, such as pregnant or fetal bodies.
The mediatization of self-tracking
Authors: Raun Tobias , Nebeling Petersen Michael
Published: January 2022

This article investigates a community of men who use the pharmaceuticals Minoxidil and Finasteride to enable and restore beard and hair growth, and who track and trace the effects on YouTube. It argues that the traditional positions of expert and patient are deterritorialized by the digitalization of health discourses and practices, and that the camera in these YouTube videos acts as a mediating/performative factor. The article seeks to answer the question of community formation among the male self-trackers. It offers a generic, analytical model where knowledge production is outlined as either expert or practitioner and community formation as either community member or community leader, both of which figure as intersecting axes on a continuum. Although derived from the case material, the article suggests that the generic, analytical model works across different audiovisually mediated selftracking communities and practices.
Regarding the Mains of Others.
Authors: Nielsen Louise Yung , Bork Petersen Franziska
Published: January 2022

The platformed logics of social media favor unique and spectacular content and thus encourage the production and display of unique and spectacular bodies. In the realm of social media, attractive and unattainable bodies have emerged as the norm rather than the exception. This article, however, sets out to investigate how a specific type of spectacular body comes into being by turning to the phenomenon of mukbangs. We explore how excessive food consumption, audiovisual aesthetics, media technologies, and platform logics all become constituents of the spectacular body’s performance. Our analysis will focus on two tendencies: First, the platformed body is distributed and comes into being through its entanglement with nonhuman agents, such as the microphone enhancing eating sounds, the camera and image composition displaying the food’s excessive quantity, and the food’s entanglement with the body through a spectacle of excess. Second, mukbang videos cater to a spectating body ready to be affected by the exceptional body capable of extreme eating and how this bodily performance transcends the medium, and the videos produce disgust or cravings.

Authors:   University of Warsaw, Niewińska Katarzyna
Published: January 2022

Purpose: The main aim of the paper is to examine the impact of external determinants on the banking stock return volatility to evaluate it in terms of the stock market capitalization. Design/methodology/approach: The research was conducted on 182 banks from 26 countries. The sample selected for the study includes all European banks listed on the stock exchange. Quarterly data from the period between 2004 and 2016 was used; it was collected and compiled over a period of 2 years. The research method applied was the panel data model with fixed effects (with or without a robust estimator) and random effects. Findings: Determinants that have a major and statistically significant impact on the analyzed dependent variables are: the unemployment rate, the real interest rate, the beta in Sharpe’s Single-Index Model and the implied volatility of the S&P 500 index and the EURO STOXX50 index. Research limitations/implications: Insights about the strength and direction of influence of these variables on stock return volatility are a valuable addition to the existing body of knowledge that investors resort to when making decisions relating to the capital market. Limitations: The main limitation of this study lies in the fact that the results of the analysis apply solely to the banking sector. Originality/value: Insights about the strength and direction of influence of these variables on stock return volatility are a valuable addition to the existing body of knowledge that investors resort to when making decisions relating to the capital market.

Authors:   University of Economics in Katowice, Maciejewski Grzegorz , Krowicki Piotr ,   WSB University
Published: January 2022

Purpose: The aim of the article is to identify online customer engagement in shopping centers (SC). Design/methodology/approach: The research was based on secondary and primary sources. The secondary sources are the subject literature, while the primary sources were obtained through netnographic research carried out on the basis of the analysis of affiliate pages of the Facebook social platform and the Google review platform of the 25 largest Polish shopping centers. Findings: The frequency of publishing posts by shopping malls and areas of customer engagement were identified. The research results show large differences between shopping centers in terms of customer engagement in a virtual environment and identify areas of customer engagement in shopping centers on the internet. Research limitations/implications: The authors of the article are aware of the limitations of their research: the analysis of statements in social media does not have to overlap with oral statements in an offline real environment. Moreover, the research results presented should only be referred to the environment of Facebook and Google. However, the variety of social media is very large, and according to the literature on the subject, the type of medium can have a large impact on the CE phenomenon. The research could be expanded by making the analysis of the type of content published by shopping centers (e.g. news, entertainment posts, shopping posts, etc.), by dividing them into categories and drawing attention to the relationships between the type of content published and the level of engagement. It could also be interesting to identify the relationship between the level and areas of customer engagement and the generation of the shopping center. Originality/value: The analysis presented in the article is of great cognitive importance. As far as the authors of the article know, this is the first publication on the engagement of a shopping center customer. The obtained results may be helpful for managers of shopping centers: they draw attention to the scale and particular areas of this phenomenon
Factors Impacting Consumer Choices From the Perspective of Owners and Managers of Beauty Parlors Located in Kraków and the Neighborhood
Authors:   University of Physical Education in Cracow, Kryczka Małgorzata
Published: January 2022

Purpose: The studies on consumer behavior on the market should take into account not only the criteria of product choices, but also the factors determining the choice of the place of purchase. The purpose of the paper is to assess the knowledge about the factors influencing the consumer choices with respect to a beauty parlor on the part of owners and managers offering cosmetic services in parlors located in Kraków and in other cities of the Małopolska Province. The significance of individual factors was assessed. Methodology: A diagnostic survey method was used for the study. An interview questionnaire comprising 51 questions was used as the research tool. The research was carried out with the use of PAPI (Paper and Pen Interview). 298 correctly completed questionnaire were qualified for statistical analyses. The choice of companies was non-random, purposeful and depended on their location in the area of Kraków and the Małopolska Province. Findings: The received results show which factors – according to the owners and managers – guide consumers in their choices of a beauty parlor. Research limitations: When analyzing the generalizing conclusions, caution should be exercised as to uncertainty with respect to the validity of the population list in the address database purchased for the study purposes from an external company. However, attempts were made to make the study representative, yet certain caution should be exercised during the generalization of the findings with respect to the entire population. Implications: Identification of factors determining the choice of a place of purchase of services is valid especially from the point of view of companies operating at a competitive market. Skillful use of knowledge on the consumer behavior often determines the efficiency of actions and the success of an enterprise. Originality: The paper presents a fragment of analysis of data procured as part of broad research of the market of beauty services in the area of Kraków and the neighborhood. At the present moment, a limited number of scientific publications about the market of beauty services is available, both in the national and regional approach.
Commitment in the German Banking and Consulting Industry: Influence of Different Leadership Styles on Employee Commitment
Authors: Zerner Vinzent , Marten Eckhard , Brandt Jens
Published: January 2022

Purpose: The success of a firm often largely depends on its employees. Therefore, we propose and test the possibility of influencing affective and normative commitment by transactional, transformational, and passive leadership styles. Implications: Demographic change is progressing slowly but steadily; here lies the crucial point. Our results show that only transformational leadership influences the commitment dimensions positively. That can help make the best use of scarce human resources to remain competitive in the long term. Originality/Value: The article provides new information concerning the relationship between transformational and transactional leadership style and their influence on commitment within the banking and consulting sector of the German service industry. It highlights the need for further research into this topic across industries and demographics. For cross-cultural (USA-Germany) comparisons, the article might help to understand differences and trends within globalization. Methodology: To address this question, we conducted interviews with 197 employees of the financial service sector in Germany to confirm the relationship between leadership styles and employee commitment. In order to verify and extend previous research, we planned an explanatory study. We used the multiple regression analysis to examine this relationship. Findings: The results provide new evidence for German participants, which show (1) that transformational leadership is the “optimum” to facilitate commitment and is completely decoupled from the other leadership styles. (2) Preliminary studies revealed a preference toward transactional leadership, which correlated positively with affective and normative commitment. The present study cannot confirm this correlation. (3) Passive leadership correlates negatively with commitment, which indicates that the avoidance of passive leadership is essential. In sum, the correlation for different leadership styles (except transactional leadership style) is higher than in the preliminary studies. This indicates that the relationship between leadership styles and affective and normative commitment is exceeding the assumptions.
Platform Economy and Product Liability: Old Rules for New Markets
Authors: García-Micó Tomás
Published: January 2022

According to statistics, Amazon is one of the most-used online marketplaces worldwide. The COVID-19 pandemic and the ensuing lockdowns to reduce the spread of the virus have shown how critical online marketplaces are to enable e-commerce and keep commercial transactions alive, especially in such times when regular commerce is disrupted. However, when we buy online, we have no chance of examining whether the product works or whether it is defective. If something goes wrong when we buy a product from a third-party seller through Amazon, as consumers, we then face the challenge of trying to file a claim for the damages that might have arisen due to the defectiveness of the product. This article explores Amazon’s position in this scenario, with reference to the case law from both US and EU courts and regulations, not solely from the point of view of Product Liability Law, but also according to the E-Commerce Directive liability.
The relations between France and the Middle East states during the presidency of Emmanuel Macron in the context of settlement of regional crises

Published: January 2022

This article analyzes the relations between France and the Middle East states through the prism of foreign policy course of Emmanuel Macron, who was elected as the president of France on May 14, 2017. The Middle East vector of foreign policy is traditional for the Republic, and therefore is one of the foreign policy priorities for the current leader. The author aim to determine the essence and key peculiarities of the Middle East course of E. Macron. For achieving the set goal it is necessary to outline the priority foreign policy vectors of the president and range of countries in the region that are subject to the measures of his chosen course; analyze in which states and to what extent the leader of the Republic continues the policy of his predecessors who were in power since the early XXI century; and changes in the relations between France and certain Middle East states. The conclusion is made on the presence of particular factors that hinder the conduct of smart policy in the region, which would meet the interests of all Middle Eastern actors. Disaccord of the French leader with his international partners regarding the Middle East regulation significantly complicates the implementation of smart foreign relative to the Arab world. E. Macron is currently paying scrupulous attention to the policy of European integration, which raises a number of unresolved issues regarding the Middle East. This alongside the domestic political issues undermines the authority of the current French leader.

Published: January 2022

This article investigates the role of positive and negative group emotions of Chileans in the territorial conflict between Chile and Bolivia, in which the latter claims access to the sea. Two studies were conducted: one following the October 2018 ruling of the International Court of Justice in The Hague (n = 463), and the other one year later (n = 457). The data were studied by statistical analysis and the results showed the relevant predictive role of positive emotions. It was established that the participants present low levels of negative emotions, but they are not willing to cede territory to Bolivia and positively value the ruling in favor of Chile. These are important issues for the future relationship between the two countries.
Electron transport properties of carbon nanotubes with radial compression deformation

Published: January 2022

In this paper, molecular dynamics simulation method is used to investigate the contacting configuration of carbon nanotubes with open ends and metal, thereby obtaining the law of radial compression deformation of carbon nanotubes. The obtained results show that after horizontally contacting the metal surface, the radial compression deformation is affected by the contact length, the diameter of the tube, the type of metal and the number of layers. Based on the first principles combining tight-binding density functional theory and non-equilibrium Green's function, the electron transport properties of carbon nanotubes with different diameters, chiralities, lamellar deformations and radial deformations are systematically studied. The obtained results show that the current of metallic single-walled carbon nanotubes presents linear change in a bias voltage range between –2 V and 2 V, and the current-voltage curve is symmetrical about the origin. The magnitude of the current is only related to the bias voltage, but not to the diameter; when the carbon nanotubes are deformed by radial compression, the current growth trend is downward and even plateau effect may appear under a larger bias voltage. The current flowing in the semiconducting single-walled carbon nanotubes decreases with the increase of radial compression deformation, and the current-voltage curve gradually transforms from semiconductor characteristics into metallic characteristics. The trend of the current-voltage curve of double-walled carbon nanotubes is consistent with that of metallic single-walled carbon nanotubes. However, the non-linear variation amplitude of the current-voltage curve of double-walled carbon nanotubes is less affected by the radial compression deformation. Owing to the increase of walls of nanotubes, the current of double-walled carbon nanotubes is twice as high as that of single-walled carbon nanotubes under the same bias voltage. The electrons can produce transitions through rapid vibration between adjacent tubes, in view of the fact that interlayer coupling characteristics of three-walled carbon nanotubes reduce the degeneracy of the energy level and larger system increases the density of states near the Fermi level, resulting in large oscillations and asymmetry about the origin of the current-voltage curve.

Published: January 2022

Fifteen peanut varieties at the pod filling stage were exposed to waterlogging stress for 7 days, the enzyme activities and fluorescence parameters were measured after 7 days of waterlogging and drainage. The waterlogging tolerance and recovery capability of varieties were identified. After waterlogging, waterlogging tolerance coefficient (WTC) of relative electrolyte linkage (REL), malondialdehyde (MDA) content, superoxide dismutase (SOD) activity, and catalase (CAT) activity, non-photochemical quenching (NPQ) and photochemical quenching (qL) of leaves of most peanut varieties were increased, while the WTC of the soil and plant analysis development (SPAD) value, PS II actual quantum yield (ΦPS II), maximum photochemical efficiency (Fv/Fm) were decreased. After drainage, the WTC of REL, MDA content, SOD and CAT activity of leaves were decreased compared with that of after waterlogging, but these indicators of a few cultivars were increased. ΦPS II, Fv/Fm and qL can be used as important indexes to identify waterlogging recovery capability. There was a significant negative correlation between recovery capability and the proportion of reduction in yield, while no significant correlation was found between waterlogging tolerance and the proportion of reduction in yield. Therefore, it is recommended to select varieties with high recovery capability and less pod number reduction under waterlogging in peanut breeding and cultivation.
Differences in the expression profiles of lncRNAs and mRNAs in partially injured anterior cruciate ligament and medial collateral ligament of rabbits
Authors: Gu Huining , Chen Siyuan , Zhang Mingzheng , Wen Yu , Li Bin
Published: January 2022

Long noncoding RNAs (lncRNAs), as a novel regulatory factor, are considered to play a vital role in various biological processes and diseases. However, the overall expression profile and biological functions of lncRNAs in the partially injured anterior cruciate ligament (ACL) and medial collateral ligament (MCL) have not been clearly explored. Partially injured models of ACL and MCL were established in 3-month-old healthy male New Zealand white rabbits. Expression of lncRNAs and mRNAs in the ligament tissue was detected by high-throughput sequencing technology, and biological functions of differentially expressed RNAs were evaluated by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. Validation of several differentially expressed RNAs was performed using quantitative real-time PCR (qRT-PCR). Protein-protein interaction (PPI) analysis and competitive endogenous RNA (ceRNA) prediction were used to identify interactions among hub genes and the interaction among lncRNAs, miRNAs, and mRNAs. The results showed that compared with the normal group, there were 267 mRNAs and 329 lncRNAs differentially expressed in ACL and 726 mRNAs and 609 lncRNAs in MCL in the injured group. Compared with MCL, 420 mRNAs and 470 lncRNAs were differentially expressed in ACL in the normal group; 162 mRNAs and 205 lncRNAs were differentially expressed in ACL in the injured group. Several important lncRNAs and genes were identified, namely, COL7A1, LIF, FGFR2, EPHA2, CSF1, MMP2, MMP9, SOX5, LOX, MSTRG.1737.1, MSTRG.26038.25, MSTRG.20209.5, MSTRG.22764.1, and MSTRG.18113.1, which are closely related to inflammatory response, tissue damage repair, cell proliferation, differentiation, migration, and apoptosis. Further study of the functions of these genes may help to better understand the specific molecular mechanisms underlying the occurrence of endogenous repair disorders in ACL, which may provide new ideas for further exploration of effective means to promote endogenous repair of ACL injury.

Published: January 2022

Las dos elecciones españolas de 2019, celebradas el 28 de abril (28A) y el 10 de noviembre (10N), estuvieron marcadas por la irrupción del partido Vox, populista de extrema derecha, que pasó de 23 a 52 diputados. El objetivo de esta investigación es analizar el impacto de su irrupción en la estructura de las comunidades (Smith et al., 2014) de las redes de debate político durante estas dos elecciones en Twitter. El estudio compara además las estructuras de las dos elecciones de 2019 con las de 2015 y 2016, así como las distancias políticas entre los principales partidos españoles. Las muestras analizadas se componen de más de 1,5 millones de tuits publicados durante las campañas electorales del 28A y el 10N. Aunque las investigaciones anteriores muestran que, en general, los patrones de interacción y las estructuras de las redes tienden a permanecer estables después de la repetición de unas elecciones, esta investigación muestra un cambio sustancial en la estructura de las redes de intersección de comunidades de retuiteadores RON (Guerrero-Solé, 2017) y en las distancias entre partidos. Específicamente, la investigación evidencia un incremento de la distancia entre los dos principales bloques políticos españoles –el formado por la triple derecha (PP, Cs y Vox) y el constituido por partidos de izquierda y nacionalistas– y (2) la ubicación de Vox en el centro del clúster de las opciones de derecha.

Los titulares periodísticos son elementos informativos cortos, pero complejos, fundamentales para captar la atención del público. En el contexto digital y de un periodismo en crisis, el intento de engañar al público para generar clics a partir de títulos falsos, conocido como ciberanzuelo, representa un peligro. En este artículo se analiza cualitativamente 31 titulares con marcas de ciberanzuelo, seleccionados después de una primera evaluación cuantitativa de 214 titulares provenientes de los tres medios de comunicación en línea sobre deportes más populares en Portugal, los periódicos A Bola, Record y O Jogo. En el corpus analizado, el ciberanzuelo juega con la curiosidad del lector a través de referencias solo inteligibles al leer las noticias, lo que reduce la dimensión informativa del título aislado. También se recurre a títulos con citas sin atribución (mediante texto o imagen) a los autores del discurso directo, a la manipulación de las declaraciones y a la ausencia de las citas destacadas en los titulares en el cuerpo de la noticia.

Este artículo se enmarca en la investigación sobre educación-entretenimiento (EE) desde la perspectiva de la persuasión narrativa. Se presentan los resultados de un estudio experimental orientado a contribuir a la mejora del diseño de estrategias de EE para la promoción de la realización de la prueba del VIH en hombres que tienen sexo con hombres (HSH). Específicamente, se analizó el efecto de la modalidad del mensaje (escrito versus audiovisual) y el rol moderador de la capacidad para generar imágenes mentales en el impacto persuasivo de las piezas de EE. En el estudio experimental participaron 109 HSH, distribuidos aleatoriamente a dos condiciones experimentales (mensaje audiovisual versus mensaje escrito). Los resultados mostraron que la capacidad de generar imágenes mentales moderaba el efecto de la modalidad del mensaje EE sobre el transporte narrativo y la identificación con los personajes. Asimismo, se constató que tanto el transporte narrativo como la identificación con los personajes actuaban como mecanismos mediadores relevantes, pero dichos efectos indirectos estaban condicionados por la capacidad para generar imágenes mentales. Estos resultados suponen un avance en el conocimiento de los procesos de persuasión narrativa, el rol de las diferencias individuales y la entrega información relevante para el diseño de intervenciones de EE

This research was conducted to determine the effect of the scallop shell lime (SSL) on the compressive strength of concrete made with Portland cement type Ico and natural aggregates from a quarry, where SSL was added at 3%, 4% and 5%. The physical and mechanical characteristics of the aggregates were determined based on the N.T.P. 400.037/ASTM C22 standard, and the mix design was carried out through the ACI method. The SSL was used due to the high calcium content present in the valve. Standard concrete controls were prepared and cured by adding 3%, 4% and 5% SSL (339.0183/ASTM C192M), which were analyzed at 7, 14 and 28 days of curing. The results showed that the compressive strength at 28 days was 242.63 kg/cm2 when 3% SSL was added, increasing with respect to the standard control by 16%. With the addition of 4% SSL, the maximum strength reached was 245.25 kg/cm2, and with 5%, the compressive strength reached was 261.17 kg/cm2, increasing by 24%. In conclusion, the SSL positively affects the increase of concrete strength, and the percentage with the highest incidence is 5%.

Aims: To examine the prevalence of skin tone dissatisfaction among Malaysian young adults and to explore the associations between social media addiction, social comparison, and skin tone satisfaction.

Study Design:  Cross-sectional survey design.

Place and Duration of Study: Universiti Pendidikan Sultan Idris, Perak, Malaysia, between December 2019 to January 2020

Methodology: Around 414 university students have partaken in an online survey consisting of a demographic questionnaire, Skin Colour Satisfaction Scale (SCSS), Upwards/Downwards Physical Appearance Comparison Scale (UPACS/DACS) and Bergen Social Media Addiction Scale (BSMAS).

Results: Descriptive analysis shows that the prevalence of skin tone satisfaction among Malaysian young adults is on a moderate level (M = 5.791, SD = 1.630), and there is a significant difference in satisfaction level among those who never tried using skin lightening products versus those who have experience in using those products, t (410.808) = -3.850, p < .001. Multivariate analysis shows that skin tone satisfaction is significantly associated with upwards social comparison (β = -.45), but not with downwards social comparison and social media addiction. Multigroup invariance analysis showed that social media addiction significantly weakens the relationship between upwards social comparison and skin tone satisfaction but has no effect on the relationship between downwards comparison and skin tone satisfaction.

Conclusion: Malaysian young adults are moderately satisfied with their skin tone, and upwards comparison can significantly influence skin tone satisfaction. The implications of this study are discussed in light of recommendations for policymakers to control the marketing of harmful skin lightening products online.
Research on Application of Artificial Neural Network in Fault Diagnosis of Chemical Process
Authors: Wang Haonan , Chen Yijia
Published: January 2022

Chemical processes are usually toxic, corrosive, flammable and explosive. If the process fails, the danger is extremely high. Traditional model-based fault diagnosis methods need to establish an accurate mathematical model of the system, while modern engineering processes are usually large in scale and complex, and it is difficult to establish an accurate mathematical model. Artificial neural network has been widely used in chemical process because of its advantages of parallel processing, self-adaptation, robustness, learnability and fault tolerance. Artificial neural networks based on "deep learning" have been successfully applied to fault diagnosis in various chemical processes. This article summarizes the principle and development process of artificial neural networks, and analyzes the research progress and application status of deep neural networks in chemical process fault diagnosis based on cases. Finally, it is pointed out that deep neural network in the field of chemical process fault diagnosis is of great significance in solving the impact of less fault data and system state changes on the fault detection rate, and promoting the industrial application of fault diagnosis models.
Effect of Vine Length and Leaf Removal on Growth and Yield of Sweet Potato [Ipomoea batatas (L.)] in the Wet Middleveld of Eswatini

Sweet potato (Ipomoea batatas L.) is an economically important food crop in Eswatini. Since its introduction, numerous agronomic research activities were carried out in agricultural research centers, non-governmental organizations, and universities. However, information on the correct vine length for planting to improve sweet potato root yield in Eswatini is scanty. Therefore, this study aimed at helping farmers with the correct vine length to be used for improved growth and yield of sweet potatoes. A field experiment was conducted at the Luyengo campus, crop production farm during the 2019/2020 crops season. It was laid in a Randomized Complete Block Design (RCBD) in a factorial arrangement with three replicates. The treatments were vines planted with or without leaves and different vine lengths; 25 cm, 30 cm, and 35 cm. Kenya white variety was used. Data were collected on growth and yield parameters. Results showed that leaf removal yielded significantly (P<0.05) lower than non-leaf removal. This may be attributed to delayed photosynthetic activity in the former.  The Vine length had no significant effect on yield. It is concluded that vines with leaves be used as planting material, and the length of vines to be used for planting should be 25 to 30 cm.
