Authors: Safdar Samyia , Faiz Shazia , Mubarak Namra 
Published: December 2021

Background: The study investigates the impact of paternalistic leadership on the performance of nurses. Furthermore, it looks into the role of self-efficacy as a mediator in the relationship between paternalistic leadership and performance. It also looks into the role of power distance as a moderator.Methods: The study used a quantitative survey-based research approach, with questionnaire responses collected over time. Initially, 315 Chinese nurses were surveyed about their views on paternalistic leadership, self-efficacy, and power distance. While their supervisors were called after 6 weeks for a dyadic answer, they were asked to offer their thoughts on their performance. The AMOS 22 software was used for confirmatory factor analysis (CFA), while the SPSS 22 software was employed for descriptive statistics, such as the correlation and regression analysis.Results: The findings demonstrated that paternalistic leadership had a beneficial impact on performance. Furthermore, the role of self-efficacy as a mediator and power distance as a moderating mediator in this relationship has been evidenced.Conclusion: The results suggest that paternalistic leadership has a good impact on nurse performance. Furthermore, self-efficacy as a mediator explains the association between paternalistic leadership and nursing performance adequately. Furthermore, power distance appeared to be a powerful moderator, as the moderated mediation results revealed that in high-power-distant societies, such as China, self-efficacy enhances the link between paternalistic leadership and nursing performance. Limitations and future directions were also discussed.

Published: December 2021

Background: The mandibular sagittal split ramus osteotomy (SSRO) is a routine operation performed to correct mandibular deformity including mandibular retrusion, protrusion, deficiency, and asymmetry. The SSRO remains a challenging procedure for junior surgeons due to a lack of adequate morphological knowledge necessary for success in clinical practice. Virtual reality (VR) and three-dimensional printed (3DP) models have been widely applied in anatomy education. The present randomized, controlled study was performed to evaluate the effect of traditional educational instruments, VR models, and 3DP models on junior surgeons learning the morphological information required to perform SSRO.Methods: Eighty-one participants were randomly assigned to three learning groups: Control, VR, and 3DP. Objective and subjective tests were used to evaluate the learning effectiveness of each learning instrument. In the objective test, participants were asked to identify 10 anatomical landmarks on normal and deformed models, draw the osteotomy line, and determine the description of SSRO. In the subjective test, participants were asked to provide feedback regarding their subjective feelings about the learning instrument used in their group.Results: The objective test results showed that the VR and 3DP groups achieved better accuracy in drawing the osteotomy line (p = 0.027) and determining the description of SSRO (p = 0.023) than the Control group. However, there was no significant difference among the three groups regarding the identification of anatomical landmarks. The VR and 3DP groups gave satisfactory subjective feedback about the usefulness in learning, good presentation, and enjoyment. The Control and 3DP groups reported positive feelings about ease of use.Conclusion: The current findings suggest that VR and 3DP models were effective instruments that assisted in the morphological understanding of SSRO-related anatomical structures. Furthermore, 3DP models may be a promising supplementary instrument to bridge the gap between conventional learning and clinical practice.

Published: December 2021

The purpose of this study is to introduce the new class of Hermite–Hadamard inequality for LR-convex interval-valued functions known as LR-interval Hermite–Hadamard inequality, by means of pseudo-order relation ( ≤p ). This order relation is defined on interval space. We have proved that if the interval-valued function is LR-convex then the inclusion relation “ ⊆ ” coincident to pseudo-order relation “ ≤p ” under some suitable conditions. Moreover, the interval Hermite–Hadamard–Fejér inequality is also derived for LR-convex interval-valued functions. These inequalities also generalize some new and known results. Useful examples that verify the applicability of the theory developed in this study are presented. The concepts and techniques of this paper may be a starting point for further research in this area.
From Utopia to Dystopia: The Demise of the Revolutionary Dream in Futuristic Cuban Cinema
Authors: Juan-Navarro Santiago 
Published: December 2021

The armed insurrection that brought Fidel Castro to power in 1959 was one of the most influential events of the 20th century. Like the Russian and Mexican revolutions before it, the Cuban revolution set out to bring social justice and prosperity to a country that had suffered the evils of corrupt regimes. A small country thus became the center of world debates about equality, culture, and class struggle, attracting the attention of political leaders not only from Latin America but also from Africa, Asia, and Europe. Its intent to forge a model society has often been described in utopian terms. Writers, artists, and filmmakers turned to utopia as a metaphor to trace the evolution of the arts in the island from the enthusiasm and optimism of the first moments to the dystopian hopelessness and despair of the last decades. Indeed, the Cuban revolution, like so many other social revolutions of the 20th century, became the victim of a whole series of internal and external forces that ended up turning the promised dream into a nightmare tainted by autocratic leadership, repression, and political and economic isolation. Although Cuban literature has extensively addressed these issues since the collapse of the Soviet Union in 1991, it is only recently that we can find similar trends in a cinematic output that portrays Cuba as a utopia gone sour. This article examines recent films such as Alejandro Brugués’ Juan de los Muertos (2011), Tomás Piard’s Los desastres de la Guerra (2012), Eduardo del Llano’s Omega 3 (2014), Rafael Ramírez’s Diario de la niebla (2016), Yimit Ramírez’s Gloria eterna (2017), Alejandro Alonso’s El Proyecto (2017), and Miguel Coyula’s Corazón Azul (2021). These films use futuristic imageries to offer a poignant (and often apocalyptic) depiction of the harsh paradoxes of contemporary life in Cuba while reflecting upon the downfall of utopia.

The objective of this pilot malacological survey was to identify the snail intermediate hosts for Schistosoma haematobium in endemic rural and semi-urban areas of Gabon. Snails were collected, morphologically identified, and tested for infection by cercarial shedding. Released cercariae were morphologically identified using low-power light microscopy. A total of six species of snails were collected throughout the study area, with Bulinus truncatus, B. forskalii, and Potadoma spp. being the most predominant species collected. Only the Bulinus species were tested for infection by cercarial shedding, of which only B. truncatus shed cercariae. Some B. truncatus shed mammalian schistosome cercariae, while others shed Gymnocephalus cercariae. Our results indicate that B. truncatus appears to be a potential intermediate host of schistosomiasis in Gabon, where cases of S. haematobium, S. guineensis, and S. intercalatum infection are reported. However, it will be important to further understand the species diversity and transmission dynamics of schistosomes.
La gestión de las competencias informacionales en la formación del conocimiento: fundamentos para un proceso de aprendizaje competente.
Authors: Anchundia Delgado Freddy Eduardo 
Published: December 2021

Las competencias informacionales consisten en poner en práctica, de forma combinada o integrada, en un contexto y con un contenido determinado, todos los recursos disponibles para solucionar con éxito problemas y aprender a aprender, a partir de la interacción efectiva con la información. Estos recursos pueden ser habilidades, conocimientos y actitudes, sin delimitación de tipo, formato y soporte. Las competencias a las que nos referimos en el presente estudio son necesarias en cualquier ámbito e incluyen otras competencias como las tecnológicas, las bibliotecarias, las bibliográficas y el pensamiento crítico. La identificación y normalización de competencias informacionales se ha llevado a cabo a través de diferentes modelos y normas. En este trabajo nos centramos en la aplicación y evaluación de varias de estas habilidades en la Unidad Educativa Fiscal “Veintitrés” de Octubre de la ciudad de Montecristi, Ecuador. Para lograr este propósito se ha tomado en consideración que la formación de competencias en la perspectiva informacional consiste en el proceso de enseñanza-aprendizaje que facilita la adquisición de tales competencias al nivel requerido. Las maneras de adquirir las competencias se enmarcan en el sistema formal, fuera del currículo o dentro del currículo como asignatura propia o parte de una asignatura. De tal manera que se deja en evidencia en este documento que la gestión de estas habilidades está comprendida principalmente por la gestión del conocimiento.

Published: December 2021

Em 2020, um Fórum de universidades públicas, em parceria com atores sociais, colocou como questão central: como inserir na agenda dos decisores políticos o tema da mobilidade sustentável, de modo que suas propostas possam ser implantadas? Este artigo busca na ciência política conceitos que permitam a construção de uma narrativa suficientemente robusta para ser assumida politicamente como agenda. Para isso, propõe-se a hipótese que define o espaço público das cidades como Commons ou Comum, aí incluídos os serviços públicos e a mobilidade urbana. Através da análise da importância das instituições e organizações da Sociedade, da identificação dos grupos de interesse e de suas lideranças e do conceito dos Commons, foram identificadas evidências que comprovam a hipótese. Conclui-se pela necessidade de repensar o papel do Estado, que passaria a ter funções de definição de diretrizes, de construção de um quadro jurídico sob o conceito do Comum, além do financiamento dos serviços e infraestruturas de transportes. A gestão da mobilidade urbana passaria a ser gerenciada por atores sociais, através de processos participativos. Para isso, é essencial que as lideranças políticas conduzam o processo político de viabilizar a agenda proposta com efetiva inclusão da sociedade na gestão dos serviços de mobilidade urbana.

Published: December 2021

La movilidad urbana es un elemento fundamental de los municipios y para poder intervenir sobre ella es necesario conocer los motivos personales para elegir un método de transporte. La pandemia provocada por el COVID-19 ha supuesto grandes cambios en la vida de las personas. El presente estudio pretende conocer si estos afectaran a la forma de desplazarse habitualmente. Para ello se contó con una muestra de 290 personas que contestaron un cuestionario sobre su situación durante la pandemia y sus preferencias de movilidad urbana. Los resultados mostraron que se producirán cambios significativos hacia la movilidad activa (caminar y bicicleta) y hacia el uso del vehículo particular y un descenso en el uso del transporte público (autobús y tren). Antes estos cambios los municipios deberán implementar medidas para potenciar el desplazamiento activo y evitar que el auge del coche cause nuevos problemas de contaminación o saturación del espacio público.

Published: December 2021

Исследуются возможности использования искусственных нейронных сетей сложной архитектуры (в частности, на основе Long Short-Term Memory, LSTM) для обнаружения сетевых аномалий, вызванных кибератаками, нацеленными на обход уязвимостей межсетевых экранов веб-приложений (Web Application Firewall, WAF), которые выявить другими средствами весьма затруднительно. Предлагается задействовать возможности LSTM одновременно c автоэнкодером. Рассмотрены вопросы программной реализации данного подхода. Экспериментальные результаты, основанные на сгенерированном наборе данных, подтвердили высокую эффективность разработки: методика позволяет обнаруживать кибератаки в реальном (или близком к реальному) масштабе времени.
The possibilities of using artificial neural networks of complex architecture (in particular, based on Long Short-Term Memory (LSTM)) are i nvestigated to detect network anomalies caused by cyber attacks aimed at bypassing vulnerabilities of web application firewalls (Web Application Firewall, WAF), which are very difficult to detect by other means. It is proposed to use the LSTM capabilities simultaneously with the autoencoder. The issues of software implementation of this approach are considered. Experimental results based on the generated dataset confirmed the high efficiency of the development: the technique allows detecting cyberattacks in real or near real time.

Authors: Li Yanan , Zhang Tianhao 
Published: December 2021

Abstract
The influence of laser fluences and scanning speeds on the morphologies of laser-induced periodic surface structures (LIPSS) on heated LiNbO3:Fe (1000 °C) was investigated under femtosecond (fs) laser scanning irradiation. Laser fluence of 8.5 kJ m−2 and scanning speed of 1 mm s−1 were found to be optimum process parameters, and large-area fs-LIPSS on LiNbO3:Fe with an area of 8 mm × 8 mm were fabricated with these parameters. The wettability of laser-textured LiNbO3:Fe changed to be hydrophilic, and the absorptance was improved substantially in the spectral range of 400–2000 nm. This technique is efficient, and environmentally friendly, which will attract tremendous interest in nano-photoelectron and nano-mechanics.
Basic investigation on identification of tissue composition based on propagation speeds of longitudinal and shear waves
Authors: Nitta Naotaka , Washio Toshikatsu , Numano Tomokazu 
Published: December 2021

Abstract
The elastic modulus of tissue as a useful biomarker of disease detection can be quantitatively evaluated based on shear wave speed (SWS) measurements in shear wave elastography. Although the longitudinal wave speed (LWS) is also expected to be a promising biomarker for disease detection, the elasticity is not always dominant because the LWS is affected by the bulk modulus. In other words, LWS and SWS may reflect different tissue properties. Therefore, in this study, based on the improvement in LWS measurement, the relationship between the composition of a phantom mixed with agar and glycerol and ultrasonically measured LWS and SWS was investigated. The LWS had a good sensitivity in detecting glycerol, while the SWS had a good sensitivity in detecting agar. The calculated Poisson’s ratio had a better sensitivity in detecting agar. In conclusion, a simultaneous measurement of LWS and SWS may help identify the tissue composition.
