Aproximación cuantitativa a la discriminación contra gays y lesbianas
Authors: Ortega Julian 
Published: July 2022

En este artículo se exponen parte de los hallazgos de la investigación doctoral del autor, cuyo objetivo principal consistió en describir y analizar los procesos de discriminación, violencia y desigualdad contra trabajadores y trabajadoras gays y lesbianas en el sector de la salud del Área Metropolitana de Buenos Aires.
La investigación adoptó un enfoque metodológico mixto. Se desarrollan parte de los hallazgos cuantitativos, más específicamente los resultados de la Escala de Discriminación Percibida y Escala de Victimización Percibida, para someterlos a discusión con otras investigaciones previas en las cuales fueron administradas. Se concluye que los hechos de discriminación y desigualdad hacia gays y lesbianas aún persisten en los espacios de trabajo de la salud, mientras que las manifestaciones más explicitas de violencia se habrían desplazado hacia la población travesti/trans.
Comunicación e historia reciente

Published: July 2022

Esta ponencia constituye un avance de investigación sobre los medios de comunicación de San Luis y las dictaduras militares de 1930 a 1966. Hemos analizado la configuración de las identidades políticas y sus disputas en el discurso mediático local. Respecto a la última dictadura cívico-militar (1976-1983) hemos relevado los medios existentes y recuperado los relatos de ciudadanos/as de San Luis y Villa Mercedes.
Advertimos que el golpe de Estado cambió la vida cotidiana de aquellas personas que se encontraban en áreas claves de la vida social y política. En cambio, quienes estaban en actividades alejadas de la vida pública, percibían a San Luis como un lugar tranquilo, a diferencia de las grandes ciudades. Sin embargo, los testimonios coincidieron en que la última dictadura cívico-militar fue el momento más oscuro de nuestra historia.
Según Mirta Varela (2002), este período tiene dos etapas, una abarca hasta 1980 y la otra desde 1980 hasta 1983. En esta, el gobierno militar enfrentó dificultades que debilitaron su mandato, tales como los cambios de figuras presidenciales, crisis económica y creciente protesta ciudadana. En este contexto, el 2 de abril las Fuerzas Armadas ocuparon las islas Malvinas, iniciando una guerra cuya derrota provocó una profunda crisis en el régimen militar. La movilización social obligó a establecer un cronograma electoral.
En este trabajo abordamos la segunda etapa, indagando las memorias de los/as ciudadanos/as de San Luis y Villa Mercedes, a través de sus relatos de vivencias y percepciones sobre la Guerra de Malvinas y la vuelta a la democracia. En ese sentido, propone un ejercicio intencional de la memoria orientado por el deseo de la comprensión de lo ocurrido, siguiendo a Pilar Calveiro (2006). Para la autora:
“La memoria, parte de la experiencia, de lo vivido, de la marca inscripta de manera directa sobre el cuerpo individual o colectivo. Sin embargo, en lugar de quedar fijada en la marca, la cualidad de la memoria reside en que es capaz de trascenderla, de asignarle uno o varios sentidos para hacer así de una experiencia única e intransferible algo transmisible, comunicable, que se puede compartir y pasar” (Calveiro, 2006, p. 377- 378).
Para conocer estos sentidos producidos recurrimos a la técnica de entrevistas semiestructuradas correspondiente a la metodología cualitativa.
Es relevante a los fines de construir memoria desde la comunicación, conocer la relación entre la experiencia de la ciudadanía, los medios y el poder.

Published: July 2022

Pentalonia nigronervosa Coquerel (Hemiptera; Aphididae) is the main vector of banana bunchy top disease caused by Banana Bunchy Top Virus (BBTV). The disease is an important and most damaging disease to the crop because infected bananas fail to produce fruits. As the vector of BBTV, P. nigronervosa is able to lives not only on banana plants but also on others plants, especially those belong to Family Zingiberaceae. The objective of this research was to reveal the biology of P. nigronervosa on banana and other plant species belong to Family Zingiberaceae commonly found around banana cultivation areas. The research was conducted in the Laboratory of Entomology, Department of Plant Protection, Faculty of Agriculture, Sriwijaya University from June to December 2021. The research was an experimental research arranged in a Completely Randomized Design using plant species as treatment and was replicated 10 times of replications. Young suckers of banana and zingiberaceous plants were used to rear the banana aphid where all biological aspects of the aphid were observed. P. nigronervosa and the young suckers were placed in a transparent pot covered with transparent plastic with a window made from cheese cloth to facilitate air movement. Room temperature was set to approximately 25oC since the aphid grow and reproduce well under such temperature. The results showed that P. nigronervosa are able to live and reproduce not only on banana but also on seven species of Zingiberaceous plants with little variation of some morphological and biological parameters. The significant different was found between biological characteristics of the aphid lived on torch ginger and cardamom which had longer life cycle but smaller fecundity compared to other experimental hosts used in the research.

Abstract
Mammalian hormones are shown to affect not only regulation of mammalian homeostasis but also play roles in cross-talk between microorganisms and their hosts. In our study, the roles of norepinephrine (NE) at two different concentrations on growth alterations, adhesion - invasion of Pseudomonas aeruginosa were investigated.
The effects of NE on the growth, adhesion - invasion of P. aeruginosa ATTC 27853 were examined in human lung carcinoma (A549) cell culture. We analysed two concentrations (HNE: 0.04μg/mL and LNE: 0.0017 μg/mL) of NE considering NE’s psychological levels in a healthy individual to imitate in vivo conditions of the host. Bacterial counts of growth and adhesion-invasion were examined by the colony counting method. Growth of bacterium was significantly reduced in the presence of NE at 90’ incubation (p: 0.0004 for high concentration and p: 0.0003 for low concentration); on the other hand, at 180’ minutes incubation, only low concentration reduced the growth (p˂0.0001). While adhesion was increased in the presence of low NE concentration (p: 0.013), there was no alteration in invasion of P. aeruginosa in the presence of NE (p˃0.05). Our results suggested that NE has different effects on the growth and adhesion of P. aeruginosa and these effects depend on concentration and incubation period.

Abstract
The essential oil obtained by hydrodistillation from the aerial parts of Salvia verbenaca (L.) Briq. ssp. clandestina (L.) Pugsl. (Lamiaceae) growing wild in Bou Saâda, pre-Saharan region of Algeria, was analyzed by GC-MS. Sixty-four compounds were detected, representing 95.6% of the whole oil, among them forty five compounds are identified in this sample for the first time. The essential oil of S. verbenaca ssp. clandestena showed the predominance of sesquiterpenes (56.4%) followed by monoterpene derivatives (35.5%). The main constituents were β-pinene (10.2%), spathulenol (8.7%), caryophylene oxide (6.1%), α-pinene (5.2%), germacrene D (5%) and α-gurjunene (4.9%). Chemical composition of the essential oil from our sample may be categorized as sesquiterpene and monoterpene chemotype among the four chemotypes identified for Salvia species.
Potential Role of LYN, CCL2, ITGB3 and IL6 Genes in the Immune Response of Porcine Buccal Mucosa Cells

Published: July 2022

Abstract
The genes considered in this study, namely, LYN, CCL2, ITGB3 and IL6 can be related to immune response in porcine buccal mucosa cells primary cultured in vitro. These genes are also responsible for, inter alia, cell migration, differentiation, proliferation and apoptosis, intracellular signal transduction, extracellular matrix binding and wound healing. A total of 20 pubertal crossbred Landrace gilts bred on commercial farms were used to obtain buccal mucosa cell cultures, which were harvested on the 7th, 15th and 30th day after initiation of the culture. Expression levels of LYN, CCL2, ITGB3 and IL6 were evaluated employing Real-Time Quantitative Polymerase Chain Reaction. All studied genes showed expression. The expression of CCL2 on day 15 was the highest of all factors measured. The greatest difference between the measurements occurred in gene IL6, between 7th and 15th day, while the least difference between the measurements occurred in gene LYN, between 7th and 15th day. Moreover, on the 7th day, LYN presented the lowest expression among all studied genes. Although in vitro conditions are much more controlled than in vivo conditions, all the factors that may positively or negatively affect cultured cells still cannot be fully predicted. Nevertheless, LYN, CCL2, ITGB3 and IL6 are a valuable starting point for studying further immunological processes in oral mucosal epithelial cells. Given their high regenerative potential, research into them is a highly valuable source of information for future wound healing therapies, where immunological processes should be carefully considered.

Authors: Krasińska Aleksandra , Mamczur Joanna , Pajdowska Manuela , Brązert Agata 
Published: July 2022

Abstract
The iridocorneal endothelial syndrome manifests in three clinical types: Chandler syndrome, progressive iris atrophy, and Cogan-Reese syndrome. It is caused by the presence of abnormal corneal endothelium on the iris stroma and anterior chamber angle leading to usually unilateral, progressive iris atrophy, glaucoma, and/or corneal edema. The etiology is yet unclear. It affects mostly young adults, mostly females. Management of iridocorneal endothelial syndrome is complex: conservative and surgical, depending on the stage of the disease and intensity of present symptoms. A 30-year-old female with a medical history of the iridocorneal endothelial syndrome was reported to the Ophthalmology Department for consultation. Slit-lamp examination revealed iris atrophy and superior-nasal corectopia in the left eye. On gonioscopy, the angle was wide open in the right eye, but there were iridocorneal adhesions and incomplete angle-closure in the left eye. The patient was provided with maximum local therapy consisting of three anti-glaucoma medications. On later check-ups, the patient presented corneal edema and increased intraocular pressure. She was qualified to ExPress mini shunt trabeculectomy with mitomycin C. Two years later, a patient came to the clinic because of increased values of intraocular pressure (up to 59 mmHg), slit-lamp examination showed that the ExPress implant was congested with fragments of the corneal endothelial cells. Thanks to YAG iridotomy the implant was recanalized.

Published: July 2022

Abstract
This article aims to present up-to-date information on ocular symptoms of pediatric multi-system inflammatory syndrome. The reviewers obtained the results based on a search of an electronic database. The pediatric multi-system inflammatory syndrome appears a few weeks after COVID-19 in children. The exact etiology remains unclear. It is diagnosed based on clinical and laboratory criteria. The most prevalent manifestation of the syndrome is non-purulent conjunctivitis (observed in around 50% of cases). The other ocular findings in the pediatric multi-system inflammatory syndrome can be; eyelid swelling, bilateral uveitis or vitreous hyperreflective dots in the posterior vitreous. The treatment of the ophthalmic symptoms is systemic and topical, targeting the enhanced inflammatory response of the organism and the presence of the given ocular findings.

Abstract
This paper aims to report clinical features, differential diagnosis and successful surgical outcome of a patient with myopic strabismus fixus, also known as Heavy Eye syndrome (HES). We present a case of a 47-year-old man who presented to the Ophthalmology Department with diplopia and poor vision. In the past, he had been diagnosed with Graves’ disease, high myopia, and secondary open-angle glaucoma. He had undergone orbital decompression and cataract surgery of both eyes. On examination, the patient had esotropia and hypotropia with limited abduction and elevation. The patient was ultimately diagnosed with HES. Yokoyama’s surgery combined with a medial rectus muscle recession in the right eye, were performed. The procedure reduced esotropia, hypotropia and improved ductions.

Published: July 2022

Abstract
The city administrative law-enforcing personnel (shorted to ‘chengguan’ in China) burnout is serious. How to timely detect, accurately measure and alleviate the burnout is an important issue for the new urban development areas in China. To construct the job demands-resources (JD-R) model, surveys in new urban areas of China were carried out. Results showed that burnout of chengguan was significantly different in terms of demographic characteristics. Job burnout of chengguan can be predicted by job demands and job resources. These findings can provide implications and guidance for the government sectors to reduce the intangible loss of human resources and to improve their health.
The Teaching Dimension of Digital Education due to COVID-19 in the Light of a Survey in Hungary
Authors: Homoki Erika , Nyitrai Laura Tímea 
Published: July 2022

Abstract

Introduction:
In the information society, the stimulus threshold for learners has changed, which requires a novel education strategy. Today, it is no longer what attracts students’ attention that it was 20 years ago. In addition to the rapid development of ICT, public education cannot go either. We believe that advanced teacher digital competence can be one of the keys of finding common ground with students and doing effective teaching work.

Methods:
In our research we examine the level of digital competence of public education teachers before the pandemic and during the 2nd wave in Hungary (2020 autumn). We examine the development of digital competence, student performance, and the effectiveness of education outside the classroom in the spring period based on teacher experience. Data from the completed forms were evaluated by using basic statistical indicators.

Results:
According to the data received, the pandemic revealed serious shortcomings in the level of development of the digital competence of both teachers and students. However, it also opened the way for catching up on both sides. Teachers were already better prepared during the second wave, so they were able to solve education more efficiently. Regional development differences and a lack of digital tools have widened the gap between students.

Discussion:
The COVID-19 pandemic has exposed these shortcomings in education. For here the process of teaching had to be placed in digital space from one moment to the next.

Limitations:
The research shows data valid only for Hungary.

Conclusions:
Expected result is the demonstrable development of competences.
EFL Instructors’ Perceptions of Utilizing Mobile-Assisted Language Learning in Higher Education
Authors: Dağdeler Kübra Okumuş , Demiröz Hakan 
Published: July 2022

AbstractIntroduction:One of the prominent approaches in language education is Mobile-Assisted Language Learning (MALL) due to recent advances in technology. To benefit from MALL effectively and develop it when it is required, it is important to know the perceptions of the ones who use it. Although much research related to students’ and teachers’ perceptions of MALL in primary and secondary education is present in the literature, research related to perceptions of instructors in higher education is limited. Thus, this study aimed at identifying the instructors’ perceptions of utilizing MALL in higher education.Methods:As the perceptions of the participants were aimed to be explored in detail, the qualitative research design was adopted. An open-ended questionnaire was developed by the researchers and administered to 24 instructors working at the English Language Teaching (ELT) departments of different universities in Turkey. The data were analyzed through content analysis.Results:It was found that the instructors defined MALL as using mobile technologies for language learning. Moreover, the participants had positive perceptions about MALL as it had some benefits, such as anytime, anywhere learning, stronger students’ interest, higher motivation and autonomy, individualized and collaborative learning. However, MALL users faced some challenges, such as weak internet connection and battery, time consumption in terms of preparing content for the class, classroom management problems and low digital literacy of both students and instructors.Discussion:The results of the study were parallel to the findings of the previous studies in the literature. This study found that MALL contributed to learning independent of time and place, high motivation and interest, saving time and energy, individualized learning, collaborative learning, autonomous learning, and learning with fun.Limitations:This study is not without limitations. Triangulation of data with in-depth interviews could be implemented to increase detailed information and reliability.Conclusions:The results of the study showed that instructors who had benefitted from technology in their teaching process had positive perceptions despite some challenges. To this end, it is suggested that MALL be utilized in language teaching by minimizing its challenges.
Same Mathematical Structure, Different Design: How Does Task Format Affect Creative Problem-Posing Performance?
Authors: Özdemir Ercan , Kar Tuğrul , Öçal Tuğba 
Published: July 2022

Abstract

Introduction:
The purpose of the study was to investigate the effect of task format on pre-service mathematics teachers’ creative problem-posing performance.

Methods:
In this quantitative study, a figural and a written pattern related to daily life with the same mathematical structure were presented to participants and they were asked to write as many problems as they could. The problems were analyzed based on whether they were viable and then on the components of fluency, flexibility, and originality of creativity.

Results:
The results of the study indicated that, although the flexibility and originality scores in the figural pattern were higher, the only statistical difference was observed in the originality component. Moreover, it has been found that some of the participants wrote similar problems in both tasks; however, the problems in the figural pattern were inclined to be more difficult.

Discussion:
Developing students’ creative-thinking skills is a main purpose of mathematics education research (Mann, 2006). However, the results of the research have indicated that the teachers’ knowledge of how to develop students’ creative-thinking skills is still lacking (Shriki & Lavy, 2012) and, consequently, students are provided with few opportunities to experience creative thinking and learning in class (Silver, 1997; Sriraman, 2005). Problem posing has a close association with creativity as well as with problem solving (Haylock, 1997; Silver, 1997). Therefore, to develop creative-thinking skills, learning environments should be enriched with problem-posing tasks. The results of this research do not assert that only one of the figural or written pattern types must be preferred to stimulate creative-thinking skills in the context of problem posing. Instead, the results emphasize that each of the written and figural patterns has its own strengths.

Limitations:
The fluency, flexibility, and originality scores are affected by the sample size. Conducting similar studies on larger samples may provide more valid conclusions about possible differences. This study has taken two different task formats into account as follow; being in written form related to daily life or including figural patterns. Figural patterns can also be structured based on whether they explicitly provide the pattern rule (Barbosa & Vale, 2016). The effect of these types of problem-posing tasks on creativity components is another case that can be investigated.

Conclusions:
Considering these results together, while including problem-posing tasks for both written and figural patterns to improve the flexibility and originality components of creativity is supported, the use of problem-posing tasks for figural patterns may be further recommended.
