Authors: De Los Reyes Mera Verónica , Jaureguizar Joana , Bernaras Elena , Redondo Iratxe
Published: May 2021

El objetivo de esta investigación fue investigar la prevalencia de la violencia de control a través de las redes sociales y el móvil en parejas jóvenes, y analizar su relación con el apego inseguro, la dependencia emocional, el sexo y la edad. Se seleccionó una muestra de conveniencia compuesta por 188 alumnos y alumnas universitarios. Las personas participantes completaron la Escala de Violencia de Pareja en las Redes Sociales en Adolescentes (e-VPA), el cuestionario Parental Bonding Instrument (PBI) y el cuestionario de Dependencia Emocional en el Noviazgo de Jóvenes y Adolescentes (DEN). El 42% del total de la muestra estudiada afirmó haber sufrido violencia por parte de sus parejas al menos en alguna ocasión y el 41.5%, que habían ejercido violencia hacia su pareja en alguna ocasión. En el caso de la cibervictimización, los chicos fueron los que más alto puntuaron. En el caso de la ciberviolencia, las variables que predecían la violencia perpetrada a través de las redes sociales fueron la necesidad de exclusividad, la relación asimétrica, el afecto de la madre y el padre, el control de la madre, el sexo y la cibervictimización. Las variables predictoras de la cibervictimización, por su parte, fueron el sexo y la ciberperpetración. Se discuten las implicaciones prácticas de los resultados del presente estudio.

Dibujo virtual como intervención previa educativa en el trastorno del espectro autista: un estudio de caso
Authors: FERNANDEZ-HERRERO JORGE , Lorenzo-Lledo Gonzalo
Published: May 2021

Abstract. En este trabajo analizamos, mediante un estudio de caso, las posibilidades que ofrece el uso del dibujo virtual inmersivo en niños con trastorno del espectro autista (TEA) como herramienta de ayuda previa a la ejecución de tareas educativas para controlar los comportamientos repetitivos y disruptivos durante las mismas. Realizamos una intervención con un niño de cuatro años con TEA y comparamos los resultados obtenidos en un contexto sin intervención previa con otros en los que, como preludio a las tareas de aprendizaje programadas, se realiza, en un caso, dibujo convencional y, en otro, dibujo tridimensional mediante realidad virtual inmersiva. Aplicamos un diseño de inversión simple y un método testado para cuantificar los efectos de las intervenciones. El experimento añade elementos novedosos y resultados interesantes a la literatura previa, que sugieren que el uso del dibujo tridimensional virtual puede ser una herramienta más efectiva en la intervención previa que las tareas artísticas convencionales para controlar el comportamiento repetitivo y disruptivo de los niños con TEA y ayudar a su concentración y atención.

Efectos del uso de dispositivos de realidad virtual sobre el control postural y el cybersickness en jóvenes universitarios
Authors: Marco-Ahulló Adrià , Monfort-Torres Gonzalo , Madera Joaquin
Published: May 2021

Abstract. El objetivo principal de este estudio fue analizar los efectos de jugar con sistemas de realidad virtual sobre el control postural y el cybersickness. La muestra del estudio estaba compuesta por 21 sujetos de 18 a 30 años de edad. Todos los sujetos jugaron con un dispositivo de realidad virtual durante 30 minutos. Además, todos los sujetos realizaron dos pretest (30 minutos e inmediatamente antes de la prueba) y dos postest (inmediatamente y 30 minutos después de la prueba). El control postural estático con ojos abiertos y cerrados y el cybersickness fueron evaluados en todas las pruebas. Los resultados mostraron diferencias significativas entre el pretest 2 y el postest 1 en tres de las cuatro variables de control postural calculadas solo para ojos abiertos (no se encontraron diferencias en la condición de ojos cerrados). Se encontraron diferencias estadísticamente significativas entre todos los momentos de medición, excepto entre el pretest 1 y el pretest 2. Estos resultados muestran evidencia de los posibles efectos negativos de la práctica recreativa con material de realidad virtual y sugiere que es necesario realizar una revisión de las recomendaciones de seguridad para este tipo de juegos.

Authors: Riera Batalla Verònica , Moragas Marta
Published: May 2021

Activity and participation in sport have garnered a great deal of attention over the past few decades, due in part to growing awareness of the benefits they offer that lead to a better quality of life. This situation has opened up new lines of investigation in the sport sciences field, including the study of physical activity and sport participation according to the perspective of Lifespan Developmental Psychology, the approach that underlies this study. The aim of this research is (1) to design an instrument to collect information on individuals’ lifelong relationships with sport and physical activity (2) to implement the instrument through a pilot test to create profiles that can be compared with other variables, all in order to study the role that physical activity and sport participation play in a range of aspects throughout the lifespan. The results indicate the questionnaire was effective and capable of collecting data on the physical and sport activities of the members of the sample at different moments in the lifespan. It was also able to generate profiles that can be used to analyze the variables of participation in sport and/or physical activity in conjunction with other variable, thus offering a way  to measure the impact of physical activity on human development.

The Impact of Partner Phubbing on Marital Quality among Married Couples in Malaysia: Moderating Effect of Gender and Age
Authors: Khodabakhsh Sonia , Ong Yong Le
Published: May 2021

Abstract. Smartphones and the internet have indeed revolutionized our lives in innumerable ways, among them the emergence of a social phenomenon called ‘phubbing.’ Phubbing is a portmanteau combining the words “phone” and “snubbing”. A person engaging in “phubbing” interacts obsessively with his/her phone rather than communicating with nearby people. Partner phubbing (Pphubbing) is defined as phubbing behaviour when in the presence of one’s spouse or significant other. The aim of this study is to explore the relationship between Pphubbing and marital quality, and to investigate the moderating role of gender and age in this relationship. The participants in the survey were 390 married adults living in Kuala Lumpur. The respondents were selected randomly and volunteered to answer a series of questionnaires made up of the Partner Phubbing Scale, the Dyadic Adjustment Scale and a section on demographic data. Results showed that Pphubbing behaviour has a significant negative relationship with marital quality. Moreover, gender and age were found to have significant moderating effects on the relationship between Pphubbing and marital quality. The reported impact of Pphubbing on marital quality was stronger among females than males, and the effects were also stronger among younger adults. These findings may have implications for family and couple counselling and for the coaching profession. Future research should be done to address this phenomenon more thoroughly.

Research on food losses and waste in North Africa
Authors: El Bilali Hamid
Published: May 2021

Background: Food losses and food waste represent an emerging problem with enormous economic, environmental, and social implications. Therefore, the reduction of food wastage is considered a promising strategy, not only to achieve food security but also to improve the food system sustainability. Food wastage is a serious issue also in North Africa region. Aims: This paper provides an overview on research dealing with food losses and waste (FLW) in North Africa (Algeria, Egypt, Libya, Mauritania, Morocco and Tunisia). Methods and Material: A systematic review was carried out in January 2018 using Scopus database. Issues addressed in the systematic review include geography of research on FLW in North Africa (i.e. countries considered or underserved), bibliometric parameters (e.g. journals, institutions) as well as thematic focus (agricultural loss, food waste). Selected records were also interrogated to see if they address the extent of FLW, the relation between food wastage and food security, economic implications of FLW, and environmental footprints of FLW. Results: The results show that research on FLW is still marginal in North Africa in general and in Libya and Mauritania in particular. Moreover, while there are some interesting pieces of research on the amount of FLW, environmental and economic impacts of FLW as well as their implications in terms of food security are largely overlooked. Conclusions: Therefore, North African researchers should pay more attention to food wastage issue. Such an endeavor should be supported by research policy in North Africa.

Keywords: Agricultural losses, Environment, Food losses, Food security, Food wastage, Food waste, North Africa.

A AUDIÊNCIA DE CONCILIAÇÃO E MEDIAÇÃO DO CÓDIGO DE PROCESSO CIVIL À LUZ DO ACESSO À JUSTIÇA E DO SISTEMA MULTIPORTAS
Authors: Muniz Fuzetto Murilo , Marques de Medeiros Neto Elias
Published: May 2021

O presente trabalho tem o escopo precípuo de discorrer, por meio do método dedutivo, sobre a possibilidade de designação de audiência de mediação e conciliação, prevista no artigo 334 do atual Código de Processo Civil, como efetivação do Sistema Multiportas e da ampliação do conceito de Acesso à Justiça. Desde que o homem passa a viver em sociedade, necessitou-se criar técnicas capazes de dirimir as disputas de interesses colidentes existentes, sendo que, após a formação do Estado, um mecanismo oficial foi criado. Provocadas pela morosidade e pela ineficiência das tutelas prestadas, o Poder Judiciário passa por verdadeira crise e não cumpre o principal papel de promover pacificação social. Por este modo, as teorias das Ondas Renovatórias e do Sistema Multiportas se apresentam como formas de propiciar ampliação do conceito de acesso à justiça, abarcando também a efetivação dos direitos ditos nas tutelas prestadas, e de fornecer um sistema com diversas técnicas previstas em que os conflitantes deverão escolher qual a que será melhor empregada no caso concreto.
O processo civil brasileiro como lugar anticientífico: entre o técnico e o político
Authors: Alves de Luna Rafael , Wanderley Gomes Neto José Mário , Latache Ribeiro de Vasconcellos Maria Paula
Published: May 2021

A presente pesquisa tem como objetivo debater se o processo civil brasileiro, diante de todo o cenário social fomentado a decisões científicas, seria um espaço aberto ao anticientificismo. A fim de sanar essa inquietação, esta pesquisa se fundamenta metodologicamente em revisão de literatura especializada sobre o tema, com discussões concretas a partir de breves análises de casos concretos. Num primeiro momento, se fará uma análise histórico-epistemológica sobre a correta leitura das conclusões científicas nos tempos atuais. Num segundo ponto, já adentrando à análise concreta de anticientificismo no processo, analisar-se-á se há a presença de anticiência por anacronismo no processo civil brasileiro, enquanto que num terceiro ponto, a análise se pauta na presença ou ausência de anticiência em um aspecto político-valorativo. Entre essas discussões, serão propostas possíveis soluções aos problemas encontrados, para ao final comprovar ou não a hipótese de existência de manifestação anticientífica no processo civil brasileiro.
Decisões estruturantes numa concepção democrática de processo: a formação participada do mérito
Authors: Maciel Júnior Vicente , Gláucia Teixeira Ank Jaíne , Gonçalves Dahas Eduardo Augusto
Published: May 2021

Para que decisões estruturais, resultado de um contraditório estruturante, sejam uma construção daqueles que arcarão com seus efeitos e não uma imposição de um Estado protetor, as decisões não podem prescindir do pleno exercício do contraditório inerente ao Estado Democrático de Direito. Questões novas a redimensionar o mérito processual devem ser submetidas à publicidade e oportunidade de deliberação dos interessados como temas novos. A proposta utiliza-se de uma metodologia dedutivo-crítica para aglutinar a segurança jurídica e possibilidade de flexibilização do mérito, ao considerar que a fonte de aglutinação de interesses sejam os temas que surjam no processo e não algum dos sujeitos processuais, permitindo um sistema aberto a participação daqueles irão responder pela efetivação das decisões estruturais a eles impostas.

Authors: Rodrigues de Mello Felipe Augusto , Notário Ligero Gilberto
Published: May 2021

O presente trabalho trata de um problema que é vivenciado há muito pelos operadores do direito, que outrora fora objeto de reflexão na literatura jurídica – sobretudo por José Carlos Barbosa Moreira, mas não excluindo outros autores -, e que, nos últimos tempos, tem sido, de certo modo, ignorado. Individualizando o objeto: a pesquisa visa a investigar como a falta de técnica processual no processo de elaboração das decisões judiciais se relaciona com o exercício do direito recursal dos litigantes, cotejando as conclusões tiradas deste primeiro exame com a verificação, através da análise empírica, da persistência deste problema na atualidade, e com as finalidades de concretização do acesso à justiça, e do aperfeiçoamento da administração judiciária.

Scipio’s Rome and Critias’ Athens: Utopian Mythmaking in Cicero’s De Republica and Plato’s Timaeus
Authors:   Culver Academies, Dutmer Evan
Published: May 2021

Scholarly debate on the relationship between Cicero’s De republica (On the Republic) and De Legibus (On the Laws) and the thought of Plato tends to focus on the supposed congruities or incongruities of the De republica and De legibus with Plato’s own Republic and Laws. Still, Plato’s discussion of ideal constitutions is not constrained to the Republic and Laws. In this essay I propose that we look to another of Plato’s dialogues for fruitful comparison: the Timaeus-Critias duology. In this essay I bring these two texts into substantive dialogue to illuminate mysterious features of both. Sketched in these complementary passages, I think, is an outline for a particular kind of approach to political theory, one proposed as novel by Cicero’s Laelius, but, as this essay hopes to show, with an interesting forerunner in Plato. I’ve called this approach ‘retrospective ideal political philosophy’ (RIPP). I end my essay with a few prospective theoretical notes on how this approach binds these two texts together.
Towards a ‘Political’ Tibullus: Ceres and Grain in Elegies Books 1 and 2
Authors:   The Graduate Center, City University of New York, Jansson Victoria
Published: May 2021

This article argues that unfulfilled prayers to Ceres in Tibullus’ elegies are symptomatic of Rome’s grain crises at the end of the Republic and beginning of Empire. My approach includes philological, socioeconomic, and psychoanalytic analysis of the elegies, in which the poet examines the shifting definition of a ‘Roman’ in his day. I seek to demonstrate the ways in which the poet grapples with the political and economic forces at work during the most turbulent period of Roman history: a time when income inequality was roughly equivalent to that of the U.S. and E.U. today.1
“Women Must Weep—Or Unite Against War”: Virginia Woolf’s Feminist Critique of Classical Epic in To the Lighthouse
Authors:   Cornell University, Pyne-Jaeger Kit
Published: May 2021

Previous scholarship on Virginia Woolf’s classicism has acknowledged her debt to Vergil primarily in the context of the Eclogues or Georgics, and her debt to classical epic as a genre rarely and sparsely. Tremper (1992) and Tudeau-Clayton (2006) have both suggested a reading of “The Lighthouse,” the third part of To the Lighthouse, as an example of modernist epic. This paper, conversely, proposes that the novel in its entirety functions as a satirical critique of epic, specifically of Vergil’s Aeneid, with the goal of demonstrating the pitfalls of epic ideology as it impacted English society during the First World War.

Под воздействием излучения N2-лазера в образцах наноразмерных частиц SiO2, спрессованных в форме таблетки, обнаружена люминесценция, спектр которой представляет собой широкую полосу с максимумом при ~460 нм. Интенсивность люминесценции зависит от продолжительности облучения, с течением времени интенсивность люминесценции монотонно уменьшается и устанавливается на определенном уровне. Предполагается, что под воздействием высокоинтенсивного УФ излучения создаются новые центры поглощения на поверхности наночастиц SiO2 и за счет поглощения части УФ излучения в этих центрах происходит уменьшение интенсивности люминесценции.
