Bullying and cyberbullying: Variables that influence university dropout
Authors: Bernardo Ana B. , Tuero Ellián , Cervero Antonio , Dobarro Alejandra , Galve-González Celia
Published: April 2020

The increase in dropout rates in higher education is a phenomenon that has generated a lot of interest because of the need to deal with its economic, personal, and social consequences, and because of its prevalence, estimated around 30% in Spain. There is a similar interest in violent behavior in university classrooms, which has also been seen to have increased in recent years. Given that, and the fact that research has shown personal variables to be more influential in dropout from higher education, the aim of this study is to explore whether those students who are the victims of bullying (both traditional and cyberbullying) are closer to dropping out from their degree courses. To that end, 1,653 first-year students doing various degree courses in the north of Spain were asked to complete a questionnaire. The results of a Bayesian analysis showed that students who were victims of bullying were more likely to consider dropping out than students who were not victims of bullying. In addition, variables related to social integration (support from friends and teachers) exhibited a moderating effect. These findings raise the urgent need to include intervention strategies in relation to bullying in university plans to prevent dropout.

El aumento del abandono en los estudios superiores es un fenómeno que suscita un gran interés por la necesidad de paliar los efectos económicos, personales y sociales que genera; y por su nivel de prevalencia, que informes recientes cifran en España en torno a un 30%. Algo semejante ocurre con los comportamientos violentos en las aulas universitarias, cuyo incremento se ha constatado en los últimos tiempos. Teniendo esto en cuenta, y dado que tal y como pone de manifiesto la investigación científica son las variables personales las que parecen ejercer un mayor peso en el abandono de los estudios superiores, el objetivo que este trabajo persigue es investigar si aquellos universitarios que están siendo víctimas de acoso (acoso tradicional y ciberacoso) pueden tener un mayor planteamiento de abandono de la titulación. Para ello, se implementó un cuestionario a 1.653 estudiantes de primer curso de varias titulaciones de una universidad del norte de España. Los resultados del análisis bayesiano realizado muestran que aquellos estudiantes que son víctimas de acoso, en comparación con aquellos que no lo son, se plantean abandonar sus estudios en mayor medida, teniendo además las variables relacionadas con la integración social (apoyo de amigos y profesores) un efecto moderador. Estos hallazgos plantean la urgente necesidad de incluir estrategias de intervención sobre el acoso en los planes de prevención del abandono universitario.
eHealth literacy of late adolescents: Credibility and quality of health information through smartphones in India

Published: April 2020

The introduction of smartphones has revolutionized how late adolescents (aged 18-21 years) access and use the internet. Vast troves of health information are today just a tap or swipe away, with smartphones and internet connectivity becoming increasingly accessible. The need for eHealth literacy among late adolescents is now gaining importance as it ensures an effective use of health information. This study conducted a survey among 427 late adolescents in order to evaluate their eHealth literacy levels; their perceptions of the quality of online health information; their level of trust and credibility in online health and checked if acquiring health information through the online medium led to a change in their behavior intention. The results showed that most of the late adolescents preferred viewing multiple websites for their health information needs. Health information in the form of text and images were preferred over video content; and most preferred accessing online health information in their native language. Cancer and obesity are the common health issues of interest to both genders. Mobile applications (apps) were the least preferred mode of accessing heath information despite the high usage of smartphones. eHealth literacy and credibility positively predicted behavior intention while quality of health information did not predict behavior intention.

La introducción de los smartphones (teléfonos inteligentes) ha revolucionado la forma en que los adolescentes tardíos (de entre 18 y 21 años) acceden y usan Internet. Hay una gran cantidad de información a solo un toque de distancia y los teléfonos móviles y la conectividad a Internet son cada vez más accesibles. La necesidad de aprender acerca de eSalud entre los adolescentes tardíos ahora está cobrando importancia, ya que garantiza un uso eficaz de la información de la salud. En este estudio se realiza una encuesta a 427 adolescentes tardíos para evaluar sus conocimientos en eSalud; sus percepciones de la calidad de la información de la eSalud; su nivel de confianza y credibilidad en eSalud y verificar si la adquisición de información de salud a través de este medio conduce a un cambio en su intención de comportamiento. Los resultados mostraron que la mayoría de los adolescentes tardíos preferían ver múltiples páginas web para sus necesidades de información de salud y la mayoría preferían acceder a información de eSalud en su idioma nativo. Las aplicaciones móviles (apps) eran el método menos usado para acceder a la información de salud a pesar del alto uso de smartphones. La alfabetización y la credibilidad de eSalud predijeron positivamente la intención de comportamiento, mientras que la calidad de la información de salud no predice la intención de comportamiento.
Monde et monde humain
Authors: Löwith Karl , Fagniez Guillaume
Published: April 2020

Dans ce texte de 1960, Karl Löwith s’interroge sur l’origine de la « perte de monde » qui caractérise selon lui la situation de l’homme moderne. Il met au jour les sources judéo-chrétiennes de l’occultation du monde naturel par le monde humain et historique, et montre comment le subjectivisme de la philosophie moderne a encore renforcé cet acosmisme. Löwith indique ainsi la nécessité et la possibilité de repenser le monde naturel comme tel, au sein duquel l’homme pourrait trouver sa juste place.
Déconstruction philosophique et déconstructivisme architectural
Authors: Bonicco-Donato Céline
Published: April 2020

Parmi les nombreux dialogues noués entre courants architecturaux et théories philosophiques, celui qu’engage le déconstructivisme spatial avec la déconstruction derridéenne apparaît profondément original. Dépassant le stade de la simple interprétation où des architectes empruntent à des philosophes leurs concepts, il a, en effet, pris la forme d’une véritable collaboration qui n’a pas laissé la pensée de Derrida indemne : à l’épreuve du parc de la Villette, le philosophe a été conduit à modifier sa perspective sur la déconstruction, tant dans son contenu que dans ses frontières disciplinaires.
Du travail social à l’intervention sociale : quand le sens fondamental de la prise en charge du corps vulnérable affirme les complémentarités professionnelles et éloigne du corporatisme
Authors: Dambuyant Gisèle
Published: April 2020

Parmi les personnes les plus violentées dans la société française contemporaine, on peut citer les femmes sans-abri. Ces conditions d’existences génèrent une exposition permanente aux risques et à la violence sous toutes ses formes : climatique, physique, symbolique, sexuelle. Dès lors, on peut élaborer, dans ces contextes, une violence holistique. Rapidement et inexorablement, la personne est atteinte et violentée dans son intégrité globale donnant lieu à des interventions professionnelles. Si la prise en charge médicale reste possible et rapide, notamment en cas d’urgence vitale, la prise en charge sociale apparaît difficile, voire impossible, particulièrement tant que ces femmes résideront dans l’espace public. Comment imaginer des interventions sociales plus adaptées évitant le découragement professionnel ? Imaginer, dès la première rencontre, un parcours d’espaces différenciés et des pratiques complémentaires permet d’envisager une prise en charge globale de ces corps de femmes violentées. Ainsi, on peut conceptualiser un parcours de « soins sociaux » pour aller vers… la reconstruction identitaire.
La violence de la peine de placement sous surveillance électronique : une violence reconfigurée pour les porteurs condamnés
Authors: Dambuyant Mathias
Published: April 2020

Cet article examine le rapport à la violence de la peine de placement sous surveillance électronique sur le quotidien de ses porteurs. Il s’agit d’une mesure technologique qui renouvelle la finalité de la peine. La violence de la peine du bracelet électronique est proprement reconfigurée car elle concerne les supports de l’identité des porteurs. Durant la peine, le corps, l’espace privé et l’emploi du temps (des porteurs condamnés) deviennent des supports de contrainte et de peine. Ces différents supports engendrent ce que nous définirons comme la « peine de soi ».
Toy stories : poupées, culture matérielle et imaginaire de classe dans la France du XIX e siècle
Authors: Maza Sarah
Published: April 2020

Dans les familles de classe moyenne et supérieure en France au xix e  siècle la poupée est un objet important aux niveaux matériel, culturel, et psychique, comme en témoigne la place qu’elle tient dans les souvenirs de femmes et la prolifération frappante de fictions centrées sur cet objet. Les décennies du milieu et de la fin du siècle voient aussi des révolutions importantes en France dans l’aspect et la production des poupées qui sont fortement différenciées selon les classes sociales. En nous inspirant des travaux de Robin Bernstein sur la culture matérielle de l’enfance, nous avançons l’argument que la poupée a joué un rôle central dans l’apprentissage des cultures et des conduites de classe pour les petites filles chez les élites françaises au cours du siècle. Un éventail d’autobiographies de femmes anonymes, peu connues, ou célèbres comme George Sand témoignent de l’importance de ce jouet dans la vie psychique des petites filles. L’abondant corpus de fictions centrées sur les poupées révèle, d’une part, leur fonction taxonomique : les différences entre elles permettent de repérer les distinctions de classe et d’en faire jouer les dynamiques. D’autre part, la poupée joue un rôle disciplinaire, invitant à des jeux de scène qui inculquent les valeurs de classe. L’article propose donc une approche dynamique de la culture matérielle et des différences sociales faisant une large part aux notions de script et de performance.
Le principe de subsidiarité en entreprise : un leurre ?
Authors: Guéry Bernard
Published: April 2020

L’expression « subsidiarité » apparaît ces dernières années dans la littérature managériale pour conseiller des voies organisationnelles innovantes. La reprise d’un concept élaboré pour rendre compte initialement de communautés politiques, pose problème. Ce travail vise à mettre en lumière la difficulté principale du passage du champ politique au champ managérial. En effet, la subsidiarité rend au niveau inférieur un pouvoir qui lui revient de droit. Or, l’approche économique de théorie des organisations, notamment à travers la théorie de l’agence, présuppose une constitution descendante de l’entreprise : ce n’est donc pas l’échelon inférieur qui attribue un pouvoir au supérieur, mais l’inverse. À moins de remettre en cause les présupposés de l’approche économique de la théorie des organisations, le principe de subsidiarité ne semble donc pas être applicable à l’entreprise. Dès lors, le principe de subsidiarité pourrait être agité comme un leurre pour faire croire au salarié qu’il est le détenteur légitime d’un pouvoir, afin d’arraisonner ce qu’il a de plus intérieur pour domestiquer sa liberté à des fins managériales.

The 5Ts for Teach Back: An Operational Definition for Teach-Back Training
Authors: Anderson Kathryn M. , Leister Sarah , De Rego Ruth
Published: April 2020

Background:

Teach Back is a health communication strategy used to confirm patient understanding in a non-shaming way. Although Teach Back is widely recommended as a best practice strategy for improving patient outcomes and organizational health literacy, there is lack of consensus in the literature on the definition of Teach Back and the best methods for training health care workers (HCWs). Our experience suggests that if you teach specific, observable skills, these can be identified in practice and potentially measured in research.

Brief description of activity:

We created a training program, the 5Ts for Teach Back, based on a standardized operational definition of Teach Back and five specific, observable components. Participants use a Teach-Back Observation Tool to identify the 5Ts in practice and during peer evaluation. The program incorporates lecture, observation, practice, and videos with good and bad examples of Teach Back.

Implementation:

The training was offered to HCWs in a large academic health care system. Flexible training options ranged from a single 4-hour training to a more comprehensive program that included clinic-specific scenarios, peer coaching, and refresher activities over a 6-month period.

Results:

The 5Ts for Teach Back operationalizes the definition of Teach Back and provides a model for training HCWs in the use of Teach Back. The 5Ts for Teach Back can be used to train any HCW. A single training session does not guarantee proficiency in practice. Through coaching and refresher activities, competence in Teach Back increases.

Lessons learned:

Teaching entire clinical units may increase effectiveness, because Teach Back becomes embedded in the unit culture. The Observation Tool can be used for training, coaching, and evaluation. The standardized method and Observation Tool are potentially useful when evaluating Teach Back during outcomes and patient satisfaction research.

. 2020;4(2):94–103.]

Plain Language Summary:

Health care workers may be clearer when giving information to patients if they use Teach Back. Studies do not show what methods are best for training health care workers how to do Teach Back. The 5Ts method breaks Teach Back into five skills that help health care workers do it well. The 5Ts can also confirm use and may be helpful for research.
La antropología al servicio del Estado: El Instituto «Bernardino de Sahagún» del CSIC (1941-1970)
Authors: Sánchez Gómez Luis Ángel
Published: April 2020

El Instituto «Bernardino de Sahagún», perteneciente al Consejo Superior de Investigaciones Científicas (CSIC), fue el principal centro oficial de investigación en antropología y etnología durante buena parte de la etapa franquista. En el presente artículo se estudian las líneas de investigación potenciadas por su director, J. Pérez de Barradas, y los condicionantes políticos e ideológicos que limitaron su actividad y condujeron a un estancamiento de la antropología cultural en el seno del CSIC.
Corpus Christi Simplicioribus: alegorías y representación de la autoridad en Valencia
Authors: Martin Vincent T.
Published: April 2020

En este trabajo estudio el misterio valenciano «El misteri del Rey Herodes>> en su contexto social y textual. Analizo la noción de la representación y la alegoría, y cómo estos conceptos llevan a un despoblamiento textual ad infinitum, borrando así toda frontera entre actor y espectador. Intento poner en evidencia no solo la concepción común de que los misteris sean un género menor, sino que sirven también como una suerte de red social para el centro urbano, tanto como la ley. Pongo a prueba la validez de las teorías de Walter Benjamín sobre la violencia divina y mítica a través de la confrontación entre Cristo y Herodes. Y examino también el proceso de crear la festa: la participación activa. Esto es la clave de la festa, ya que el misteri es sólo una parte del espectáculo.
La tradición moderna y la edición del Romancero hispánico. Encuestas promovidas por Ramón Menéndez Pidal en Asturias (1911-1920)
Authors: Cid Jesus Antonio
Published: April 2020

La edición científica del Romancero General Hispánico ha sido un proyecto varias veces abordado, desde mediados del s. XIX, por distintos estudiosos y con criterios muy distintos. Sin embargo, hasta hoy tal proyecto no ha sido llevado a término satisfactoriamente. En la primera parte de este artículo se intenta explicar la razón del fracaso de uno los intentos más sólidos de edición del Romancero, el planeado por el hispanista R. Foulché-Delbosch en colaboración con R. Menéndez Pidal a principios de siglo. Por razones análogas, el Romancero que emprende Menéndez Pidal en solitario hacia 1904 no llegaría a iniciarse hasta varias décadas después. Este último hecho guarda relación -según aquí se sostiene- con el cese de la actividad personal directa de Menéndez Pidal en las encuestas de campo a partir de 1910. Se concluye que la propia riqueza y vitalidad de la tradición moderna de la balada hispánica, insospechadas hasta entonces, obligó a reformular el alcance, organización y dimensiones de la edición global del Romancero, y diferirla hasta obtener un conocimiento suficiente de la tradición oral del Romancero en todas sus ramas geográficas y lingüísticas. Tal conocimiento sólo podía ser resultado de encuestas realizadas por distintos estudiosos o etnógrafos a lo largo de un dilatado plazo de tiempo. En una segunda parte del trabajo se estudian dos de las encuestas más productivas, entre las fomentadas por Menéndez Pidal a partir de 1910: las que llevan a cabo en Asturias Josefina Sela (1914-1920) y el musicólogo Eduardo Martínez Torner (1914-c. 1930).
QUANTIFICATION OF MENTAL STRESS USING COMPLEXITY ANALYSIS OF EEG SIGNALS
Authors: Ahammed Kawser , Ahmed Mosabber Uddin
Published: April 2020

Detection of mental stress has been receiving great attention from the researchers for many years. Many studies have analyzed electroencephalogram signals in order to estimate mental stress using linear methods. In this paper, a novel nonlinear stress assessment method based on multivariate multiscale entropy has been introduced. Since the multivariate multiscale entropy method characterizes the complexity of nonlinear time series, this research determines the mental stress of human during cognitive workload using complexity of electroencephalogram (EEG) signals. To perform this work, 36 subjects including 9 men and 27 women were participated in the cognitive workload experiment. Multivariate multiscale entropy method has been applied to electroencephalogram data collected from those subjects for estimating mental stress in terms of complexity. The complexity feature of brain electroencephalogram signals collected during resting and cognitive workload has shown statistically significant ([Formula: see text]) differences across brain regions and mental tasks which can be implemented practically for building stress detection system. In addition, the complexity profile of electroencephalogram signals has shown that higher stress is reflected in good counting compared to bad counting. Moreover, the support vector machine (SVM) has shown promising classification between resting and mental counting states by providing 80% sensitivity, 100% specificity and 90% classification accuracy.
IDENTIFYING THE CORRELATION BETWEEN ENCEPHALOGRAPHIC SIGNAL IRREGULARITY AND HEART RATE VARIABILITY TO DIFFERENTIATE INTERNALLY AND EXTERNALLY OPERATIVE ATTENTION
Authors: Kumar M. , Singh D. , Deepak K. K.
Published: April 2020

This study identifies a correlation between low-frequency heart rate variability (LF-HRV) and encephalographic (EEG) complexity to differentiate internally operative attention (INT) and externally operative attention (EXT). Electrophysiological fluctuations in response to Posner’s spatial orienting paradigm were explored in 14 healthy volunteers who participated in 6 alternating sessions of attention tasks. HRV analysis was used to measure heart rate fluctuations, and approximate entropy (ApEn) was used to measure changes in the irregularity of EEG and HRV. Power spectral analysis of HRV revealed that there was found to be a significant difference between INT and EXT for HRV-low frequency (HRV-LF) and LH/HF ratio. ApEn for RR-interval time series increased for both attention tasks as compared to baseline and recovery session. The relationship between HRV-LF and EEG spectral power measured at F4 revealed significant negative correlation during ([Formula: see text], with [Formula: see text]) EXT than ([Formula: see text], with [Formula: see text]) INT. Furthermore, a significant positive correlation, yet of moderate strength was noted between HRV-LF and ApEn of EEG signal measured at POz ([Formula: see text], with [Formula: see text]) during EXT as compared to INT ([Formula: see text], with [Formula: see text]) and, a significant negative correlation was observed between ApEn of RR-interval and ApEn of EEG signal measured at POz ([Formula: see text], with [Formula: see text]) during EXT as compared to INT ([Formula: see text], with [Formula: see text]). Thus, it is evident that EXT leads to more irregularity in parietal regions of the brain than the INT. During EXT, the irregularity over the parietal region linked to increased sympathetic activity as compared to INT and corresponds to decreased heart rate. These results may benefit in designing robust human-computer interfaces and accelerated training paradigm to raise an athlete’s performance.
The Effect of Blood Glucose on Quiet Standing Balance in Young Healthy Individuals
Authors: Breloff Scott P. , Bachman Jessica L. , Lugade Vipul A. , Stuka Andrew D.
Published: April 2020

Falling is one of the leading causes of accidental injury and death among elderly adults and construction workers, with costs exceeding US$31 billion each year. Having good balance reduces the likelihood of falling — therefore it is important to determine which possible factors might influence balance. The purpose of this study was to determine if consuming three different types of breakfast altered blood glucose levels in such a way that young healthy individual’s balance control was compromised. Balance was then measured while the subjects completed single- and dual-task standing trials with eyes open and closed. Although changing blood glucose did alter quiet standing balance — as measured by the separation distance between the COG and COP, the velocity of the COM, and the total distance traveled by the COG and COP along the anterior–posterior (AP) and medial–lateral (ML) axes — the results were contradictory to what was hypothesized. Subjects with lower blood glucose swayed less than those with higher blood glucose. This could potentially be due to the habitual skipping of breakfast in young adults. Though the changing of blood glucose did influence quiet standing balance of young healthy adults, it was not in a way which increased the risk of falling.
Exploring the Scope of User Resistance
Authors: Aseidu Sylvester Tetey , Boateng Richard
Published: April 2020

Although innovation adoption has been given much attention in information systems (IS) literature, it has less to account for in user resistance. This chapter contributes to this ongoing debate through a bibliometric review of the user resistance research for the period 1978 to the first quarter of 2019 to provide a coherent overview of the recent research trends and theoretical cornerstones. The authors merged two approaches—co-citation analysis and bibliographic coupling—to (1) create a visualized network of articles that focus on ‘user resistance' and (2) to create distinct yet related clusters of articles related thematically. In the findings, they illustrate via the co-citation analysis that user resistance research builds on four main theoretical cornerstones: status quo bias and equity implementation theories, organizational change, social influence and perceived usefulness, power and politics. In conclusion, more research is needed on this theme from a developing economy perspective as IS adoption and usage gains maturity.
Electricity Infrastructure Technical Security
Authors: Hromada Martin , Rehak David , Walker Neil
Published: April 2020

In general, energy infrastructure is a basic but very complex system of elements, interconnections, functional inputs and outputs, which creates the need to break down subsystems, systems, and infrastructure areas. The aim of this chapter is therefore to discuss the possible implementation of approaches to risk assessment and risk management in relation to the application of technical security measures. This chapter of the book will therefore discuss risk analysis methods where the transition from general approaches to risk analysis, through risk identification methods and procedures and the assessment of major industrial and technological risks, to specific risk analysis methodologies for electricity infrastructures, will be presented. An important part of the chapter is also the introduction of practical approaches and methodologies that are accepted as “best practices” in connection with ensuring the technical security of electricity infrastructures.

Published: April 2020

The new industrial revolution will encompass massive change. Manufacturing Companies are pursuing digitalization and trying to figure out how to implement collaborative robots, all the while trying to manage data safety and security. It is a big challenge to deal with all the needed infrastructures to handle the big data digitalization provides whilst having to account for the shielding of it. Even more so when one has to succeed at it while taking care of the workers, the sustainability of their jobs, the implementation of safe practices at work, based on the contributions of the whole, through efficient vertical communication, imbued with Safety Culture and aiming the sustainability of the Company itself. This chapter proposes to address the role of standardization in managing industry 4.0, where culture, Risk Management and Human Factors are key, and how the tools provided by these norms may contribute to nimbly balance each Company's needs.
The Aesthetic of New Media and Communication Devices in Film and Television Language
Authors: Hermida Alberto
Published: April 2020

The establishment of mobile media and the development of Web 2.0, in parallel to the current omnipresence of user interfaces and the multiscreen landscapes, have led to the consolidation of changes in all spheres of life. Subsequently, and due to the hybridization and remediation processes inherent to the digital environment, the more conventional media have been considerably affected by these transformations in the media ecosystem. Accordingly, this chapter examines the influences and formal loans in film and television language by analyzing the aesthetic transfers occurring in fiction and non-fiction.
Audience Engagement and Transmedia Adaptation
Authors: Heredia-Torres María
Published: April 2020

This chapter analyses the transmedia strategy followed by the creators of The Lizzie Bennet Diaries (2012-13). This web series uses different platforms to recreate the plot of Jane Austen's Pride and Prejudice. Moreover, the usage of these platforms encourages fan participation and engages the audience. In order to explore the employment of transmedia, different approaches are applied to understand the construction of the series and the role of the audience. Furthermore, different transmedia strategies to plan the story are also considered. This analysis is particularly relevant because it shows how transmedia can be employed to adapt a classic novel for a digital generation, and how the audience becomes part of the story itself.
Augmented Reality and Franchising
Authors: Pérez-Gómez Miguel Ángel
Published: April 2020

In 1996, with the advent of video game franchises like Pokemon (Game Freak, 1996-), the concept of media mix (originally a Japanese concept that refers to the communicative strategies in which media content is spread across multiple platforms) began to take off. However, media mix is not exclusively limited to Japanese productions. In 2009, Novarama, in collaboration with Sony Computer Entertainment Europe, launched the Spanish Augmented Reality video game Invizimals. A decade later, this universe has notably expanded across different platforms, evolving considerably from its original format: but falling short of integrating the entire universe. In this chapter, we examine hybridation between transmedia strategies and media mix through the Invizimals universe to demonstrate how the franchise has expanded a decade later to the point where it has consolidated its own strategic model for developing content.
An Analysis of Netflix España Campaigns
Authors: Bravo Irene Raya , Rubio-Hernández María del Mar
Published: April 2020

Since entering the Spanish market in October 2015, Netflix has engaged in several advertising campaigns, deployed online, which are designed to appeal to some aspects of Spanish culture. The obvious aim has been to promote Netflix programming and to establish a connection to the Spanish audience. The strategy, which alludes to recognisable elements from the culture of the target audience, has been developed to promote both international productions as well as national ones, in which cultural references are reflected in the context in which they emerge. This chapter analyses the trajectory of Netflix Spain's marketing campaigns over the last three years, focusing on Paquita Salas as a case study, and determining to what extent the advertising exploits current local social and cultural situations in order to gain more engagement on the part of the spectator.
Acceptance of Virtual Reality Games
Authors: Kosa Mehmet , Uysal Ahmet , Eren P. Erhan
Published: April 2020

As virtual reality (VR) games are getting more widespread, the need to understand the interaction between players and the VR games is gaining prominence. The present study examines player endorsement of virtual reality games from an amalgamation of technology acceptance, self-determination, and flow theory perspectives. A survey was carried out with participants (N = 396) who had played a VR game at least once and at most five times. Structural equation modeling analyses showed that perceived ease of use was the primary predictor for satisfaction of self-determination constructs (autonomy and competence) and flow constructs (immersion and concentration), which in turn predicted player enjoyment. Accordingly, the results suggest the importance of including self-determination constructs in addition to the flow perspective within the context of technology acceptance model, for explaining the acceptance of VR gaming. Findings also showed that enjoyment resulted in positive attitudes towards VR gaming, and these attitudes predicted intention to play VR games.
Localization of Autonomous Robot in an Urban Area Based on SURF Feature Extraction of Images

Published: April 2020

An autonomous robot is now an internationally discussed topic to ease the life of humans. Localization and movement are two rudimentary necessities of the autonomous robots before accomplishing any job. So, many researchers have proposed methods of localization using external tools like network connectivity, global positioning system (GPS), etc. However, if these tools are lost, either the movement will be paused, or the robot will be derailed from the actual mission. In these circumstances, the authors propose an approach to localize an autonomous robot in a specific area using the given set of images without external help. The image database has been prepared and kept in the internal memory of robot so that image matching can be done quickly. The localization method has been accomplished using three algorithms: (1) SURF, (2) ICP-BP, and (3) EMD. In the evaluation, SURF has been found better than ICP-BP and EMD in terms of accuracy and elapsed time. The authors believe that the proposed method will add value to other methods using some external tools even when those tools are unavailable.
Embeddings or disembeddings? A discussion about Physical education and proposals for high school
Authors: Machado Roseli Belmonte , Da Fonseca Denise Grosso , Tavares Natacha da Silva
Published: April 2020

In addition to discussing Physical Education and its curricula from the advent of recent educational policies, this article also proposes to move an important debate on the last stage of Basic Education, High School. This article presents analyses developed from the research that aimed to reflect on the inclusion of Physical Education in the Languages Area, discussing the relationship between the curricular proposals for Basic Education and the pedagogical practice of Physical Education teachers in High School. The methodology was based on Foucault’s studies. We intend to show that projects for training and formatting individuals have been placed in society and the current Brazilian reality, especially in the case of secondary education. We understand that these training projects are transposed with other discourses in order to gain the empathy and compliance of the population, which had long been questioning the organization and the teaching model. However, this is in fact a setback because, instead of reformulating methodologies and allowing knowledge to make sense for students, it causes them to remove from their formation that which does not seem interesting or useful to them, and, if in the future these individuals identify those gaps, they will be solely responsible for solving them.
Strategies of resistance and empowerment of portuguese women coaches in sports
Authors: Mourão Ludmila , Silva Paula , Goellner Silvana Vilodre , Gomes Paula Botelho
Published: April 2020

The participation of women in sports is the subject of analysis of several studies that continuously evidence inequality and asymmetry in relation to men in the different spheres of activity within this field. The objective of this study is to comprehend male hegemony as coaches and how it is accepted and/or contested in the sports environment by identifying attitudes that incorporate this male dominance or that contradict and resist it. The sample of this study is composed of interviews with 37 Portuguese female coaches in both individual and team sports. The results indicate that the presence of women in leadership positions in sports, such as of head coach, does not ensure in itself an objection to male hegemony. It becomes necessary that women incorporate the concept of “agency” in order to identify and implement strategies that resist and consequently change the patriarchal structures that perpetuate the underrepresentation of women in coaching sports.
Investigating the Properties and Structure of Polyurethane Elastomers with Monoethylene Glycol Chain Extender
Authors: Somdee Patcharapon , Lassu-Kuknyo Timea , Konya Csaba , Szabó Tamás , Marossy Kálmán
Published: April 2020

The effect of monoethylene glycol (mEG) acting as chain extender in polypropylene glycol (PPG-4000) and 4,4ʹ-diphenylmethane diisocyanate (MDI) reaction was investigated. Polyurethane elastomers (PUR) were changed from flexible to rigid materials by varying the mEG content. Results show that Shore A and D hardness values trend to increase with increasing mEG content. It appears that increasing the chain extender content increases the hard segment content in the polyurethane structure. Moreover, increasing the mEG content increases Young’s modulus and the tensile strength of PUR, while elongation at break decreases. The chemical structure of the hard segment of PUR was characterized by Infrared (IR) spectroscopy. IR spectra exhibited the bands typical for PUR consisting of –NH, CH2– and C=O groups. The spectra reveal a few interactions between the polymeric chains that appear to be responsible for the shift of transmittance peak and decrease of some peak intensity. This may be due to the hard segment aggregating more to form domains in the PUR when mEG content was increased.
Hydrogen-Induced Microstructure Optimization of the Ti-6Al-4V Alloy
Authors: Mohsun Mohammed Kasim
Published: April 2020

To obtain advanced materials through the development of traditional materials without the addition of another alloying element, advanced heat treatment can be used. One such innovative process is a thermo-hydrogen treatment (THT); it facilitates a purposeful adjustment of an improved microstructure using hydrogen as a temporary alloying element within heat treatment. In this paper, the five-step process of homogenization, hydrogenation, solution treatment, dehydrogenation, and aging was used in THT. Scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), backscattered electron (BSE), electron backscatter diffraction (EBSD), and X-ray diffraction (XRD) were utilized to analyze the phases and phase transformations in Ti-6Al-4V. Three different homogeneous microstructures were established for the investigation using different homogenization parameters values. The hydrogenation was carried out for these microstructures via hydrogen gas charging leading to hydrogen concentrations for the formation of hydride (δ TiH2). After the solution treatment at a temperature above β transus temperature (Tβ), the metastable phases of a martensitic structure consisting of a mixture of α ́ (hcp) and α ́ ́ (orthorhombic) was found. Steps 4 and 5 of THT were a vacuum annealing (hydrogen degassing) followed by aging treatment. The aging treatment was applied to complete the martensite phase decomposition and the precipitation of two phases. By means of this THT cycle, very fine equiaxed microstructures could be established. These microstructures consist of the αs phase (secondary α) in the β phase matrix and the α2 phase (Ti3Al) in the αp phase. The precipitation of these phases increases the strength of the Ti-6Al-4V alloy and, consequently, enhances the mechanical properties. No evidence of the δ phase was found.

For a unique microstructure creation, thermo-hydrogen treatment (THT), using hydrogen as a temporary alloying element within the heat treatment, is applied. This advanced heat treatment requires reliable data about the hydrogen diffusion coefficient (DH) for understanding diffusion kinetics and its effect on the mechanical behavior of the resulted phases. In this research, three different homogeneous microstructures were established for the investigation using different homogenization parameters. After that, the concentration of hydrogen, charged in the half-length of thin titanium rods via electrochemical hydrogenation, is specified. Then, a diffusion annealing heat treatment was carried out at different temperatures, leading to hydrogen diffusion in the hydrogenated specimens. Furthermore, DH was systematically determined using two methods including the explicit finite difference method (EFDM) and Matano technique (MT). For this purpose, Abaqus software was employed for modeling the hydrogen gradient established in the specimens. Additionally, scanning electron microscopy (SEM) was used for the microstructure examination in order to specify the influence of different hydrogen concentrations on the hydrogenated specimens. The experimental outcomes reveal a substantial effect of the β phase stability and grains sizes of the β and α phases on the hydrogen diffusion. Correspondingly, the results confirm that DH was independent of the hydrogen concentration, and obeys an Arrhenius-type temperature dependence. Furthermore, hydrogen diffusion in the α+β titanium alloys Ti-6Al-4V was slower in comparison to the hydrogen diffusion in the metastable β titanium alloys Ti-10V-2Fe-3Al. In conclusion, it was observed that DH is influenced by the previously performed heat treatments that determine the resulted microstructure types, and a slight influence of the volume fraction of the α phase on DH was observed as well.

Multi-layered metal composites have received considerable attention due to their improved mechanical and physical properties. In this study, Al6061/Al2024 composite was processed by accumulative roll bonding (ARB) as a severe plastic deformation technique. Mechanical properties of processed material were evaluated using the uniaxial tensile test and shear punch test method (SPT). The correlation between the results of the tension experiments and shear strengths was calculated. Experimental results demonstrated that the shear strength enhanced with increased number of ARB passes. However, the elongation under shear manifested a reduction when the number of ARB passes increased. Inspection of the results of tensile tests and SPT revealed that they follow a similar trend for both strength and ductility. Therefore, it can be asserted that the shear punch test represents a useful and complementary tool in the mechanical analysis of the ARB sample.

Published: April 2020

A laboratory analysis of concrete samples requires significant experimental time and cost. In addition, advancement in data mining provide valuable tool for researchers to extract information regarding relations among experiment and physical properties in a more elaborate way to improve prediction models performance and guide concrete mix design. A 90 samples data set is developed and used in this research. The experiment is designed to study the effect of natural silica addition at different levels on physical properties of concrete mainly compressive strength. Compressive strength is measured after 3 and 28 days for different levels of milling time. Support vector regression and neural network models are developed for predicting the compressive strength of concrete using five input variables including silica additive fraction. The SVR model metrics are compared with ANN model and showed good correlation coefficient of 0.929 but less than ANN. The advantage of SVR over ANN is shown in the developed regression model which can be interpreted physically. The silica fraction variable ranked third after curing time and cement ratio variable which indicates its importance.

The important portion of machining costs associated with cutting inserts and scraps induces the search for better effectiveness in turning. This paper presents the results of an exploratory study on the influence of tool flank wear on roughness indicators (arithmetic average roughness, root mean square roughness and maximum height of the roughness profile). The objective is to determine which of these indicators is best correlated with the cutting tool flank wear. In order to do this, specimens of AISI 1045 are machined until the end of life of a cutting insert. Significant, strong and positive correlations are found between all three roughness indicators and the tool flank wear. The most significant correlation is found with the arithmetic average roughness and the root mean square roughness of the profile. The choice of the end-of-life criteria for cutting inserts in industrial contexts is also discussed.

The Una River and its basin constitute an important water source for public supply in the municipality of Taubaté (SP, Brazil). The present work aimed to investigate biochemical markers of environmental pollution in the Una river basin using enzymes extracted from the kidneys, gills and brains of Astyanax bimaculatus, a fish commonly found in this basin. Tissue levels of superoxide dismutase (SOD), catalase (CAT), malate dehydrogenase (MDH), lactate dehydrogenase (LDH) and acetylcholinesterase (AChE) were determined in tissues of A. bimaculatus collected in water bodies localized at Fazenda Piloto of the University of Taubaté (P1), the Remédios municipal road (P2) and at a small lake near the neighborhood of Ipiranga (P3), all located in the municipality of Taubaté. The lowest activities of renal and gill SOD were found in fish collected from P2 and P3, respectively. Renal and branchial CAT, renal MDH and LDH, as well as the activity of cerebral LDH were not affected by collection site. The activities of brain MDH and AChE were higher in fish from P3 in comparison with P1. These results along with earlier published findings, indicate that the hepatic SOD and CAT, gill SOD and LDH, muscle MDH and brain MDH and AChE are sensitive to contamination in the environment and hence can be considered as good candidate biomarkers of environmental change in the Una River basin.

Contrary to the traditional assumption of interest rates on government debt exceeding economic
growth, negative interest-growth differentials have become prevalent since the global financial
crisis. As these differentials are a key determinant of public debt dynamics, can we sleep more
soundly, despite high government debts? Our paper undertakes an empirical analysis of interestgrowth
differentials, using the largest historical database on average effective government
borrowing costs for 55 countries over up to 200 years. We document that negative differentials
have occurred more often than not, in both advanced and emerging economies, and have often
persisted for long historical stretches. Moreover, differentials are no higher prior to sovereign
defaults than in normal times. Marginal (rather than average) government borrowing costs often
rise abruptly and sharply, but just prior to default. Based on these results, our answer is: not
really.
