La estructura de la ftalimida es considerada un bloque de construcción para el desarrollo de nuevos agentes anticancerígenos. En este trabajo, se evaluó la actividad antiproliferativa de cuarenta y tres derivados de ftalimida contra las líneas celulares cancerígenas de cérvix (HeLa), hígado (HepG2), mama (4T1), y la línea celular normal de fibroblastos murinos (3T3). Por último, se realizó un análisis de acoplamiento molecular de los derivados de la ftalimida en el sitio activo de la enzima metiltransferasa 1 de DNA (DNMT1, por sus siglas en inglés) y el receptor del factor de crecimiento endotelial vascular 2 (VEGR2, por sus siglas en inglés) como posibles blancos farmacológicos. Los compuestos C16, E11 y E16 mostraron la mejor actividad antiproliferativa contra las líneas celulares HeLa y 4T1. Solamente, el compuesto H16 disminuyó 32% la proliferación celular de la línea HepG2. Los compuestos H5, H16, E2, E16 y C1 no afectaron la proliferación celular de la línea 3T3. El análisis de acoplamiento molecular demostró que los derivados de la ftalimida tienen una mayor afinidad que la S-adenosil-l-homocisteína, un potente inhibidor de la metiltransferasa 1 de DNA. Sin embargo, los resultados del acoplamiento molecular no se correlacionan con los efectos antiproliferativos; lo cual sugiere que los compuestos activos tienen otro mecanismo de acción.
Tectonica penecontemporánea a lo largo de la costa mexicana del Océano Pacífico

Published: June 2021

A mediados del siglo pasado, Alejandro Von Humboldt (1867) expresó la idea de que la gran concentración de volcanes a lo largo del paralelo 19° lat N, a través de México, se debía a una fractura mayor de la corteza terrestre. Unos cien años más tarde, las investigaciones hechas en el Océano Pacífico por geólogos de la Institución Scripps de Oceanografía probaron concluyentemente la existencia de tal fractura que continúa fuera del continente en el Océano Pacífico por la Zona de Fracturamiento Clarión. A la luz de esos resultados, las Islas Revillagigedo representan los picos salientes de enormes complejos volcánicos que Se elevan abruptamente desde profundidades de 4,000 metros dentro de la zona mencionada y que son comparables a los gigantescos volcanes Popocatépetl e Iztaccíhuatl en el territorio mexicano.
Parámetros microfísicos en relación con la distribución y precipitación de nubes tropicales y su modificación
Authors: Kessler III. Edwin
Published: June 2021

Se han considerado los parámetros microfísicos y el perfil de viento vertical respecto a formas de distribuciones espacial y temporal de Ia precipitación tropical. Para un campo de velocidad vertical particular, se ha concentrado Ia precipitación bajo un centro de corriente ascendente respecto a Ia alejada del centro por números relativos de pequeñas gotas en incremento en la distribución de partículas de lluvias. El aumento de eficiencia en recolección de lluvia por nube y un más rápido índice de crecimiento de partículas de nubes reduce el total de condensado que se lleva a niveles altos y se pierde por efectos de divergencia horizontal a la precipitación inmediata en tierra, relacionándose el tiempo de iniciación de Ia precipitación en ese Iugar a Ia velocidad de la corriente de ascenso, los parámetros de distribución de gotas, Ia eficiencia de recolección y los índices de conversión de nubes. Para alterar apreciablemente Ia distribución de lluvia en tierra se requieren cambios relativamente grandes en los parámetros microfìsicos, ya que las respuestas de distribuciones del agua en el sistema del modelo usualmente tienden a desviar los efectos de cambios microfísicos. Se discuten las posibles respuestas de la nubosidad y precipitación a modificaciones de parámetros microfísicos a la luz del modelo, suponiéndose que la distribución de corrientes de ascenso no es afectada por variaciones de perfiles verticales de nubes y precipitación y anotándose también Ia posible significación de procesos microfísicos para el albedo y clima de Ia Tierra.
Un estudio sismológico propuesto para el Golfo de California
Authors: Nopoff L. K. , Pilant W. L.
Published: June 2021

El Golfo de California parece ser la extensión lineal de la Falla de San Andrés. Hamilton (1961) ha sugerido que la Península de Baja California fue separada lateralmente de la tierra mexicana en tiempo posterior al Mesozoico Superior, por un movimiento de tipo transversal con inundación del espacio resultante. El movimiento primario, según Hamilton, tuvo desplazamiento lateral derecho paralelo al eje del Golfo, combinado con movimientos sísmicos a lo largo de la Falla de San Andrés hacia el norte y postuló que el Cabo San Lucas y la Bahía de Banderas fueron estructuras en contacto en un tiempo. El desplazamiento de ambos puntos geográficos concuerda con el deslizamiento a lo largo de la Falla de San Andrés (Crowell, 1962) en la región del norte. Allison (1964) ha expresado también algunas conjeturas diferentes sobre el origen del Golfo de California.

Reconocimientos y observaciones recientes en distintas partes del mundo indican que Ia discontinuidad de Mohorovicic se desvía fuertemente de Ia condición de horizontalidad. Se conoce desde hace mucho tiempo que el espesor de Ia corteza es distinto bajo los continentes que· bajo los océanos. Esto implica alguna inclinación de Ia discontinuidad a lo largo del límite océano-continente. El mismo cambia de grosor parece estar presente debajo de las cadenas montañosas. Aun debajo del interior de los continentes en donde no hay montañas presentes, como bajo el Lago Superior en los EE.UU.

Monocyte Chemiluminescence Traits in Gastric Cancer
Authors: Smirnova O. V. , Sinyakov A. A. , Tsukanov V. V.
Published: June 2021

Aim. A study of monocyte chemiluminescent activity at variant stages of gastric cancer.

Materials and methods. The study enrolled 90 gastric cancer patients and 70 healthy donors. Spontaneous and induced chemiluminescence in monocytes was assessed for 90 min with a “BLM 3607” 36-channel chemiluminescence analyser (Russia). Opsonized zymosan-induced chemiluminescence enhancement was measured as a ratio of the areas under the induced vs. spontaneous chemiluminescence curves, the activation index. Statistical significance was estimated with the Mann—Whitney criterion (p < 0.05).

Results. The maximal spontaneous monocyte chemiluminescence intensity significantly decreased in stage IV gastric cancer patients compared to the control cohort (p = 0.035). Time to maximum in spontaneous chemiluminescence increased in all gastric cancer patients vs. control (p = 0.001), and in stage IV gastric cancer vs. stage I patients (p = 0.043). The areas under a curve in spontaneous and induced monocyte chemiluminescence increased in all gastric cancer patients vs. control (p = 0.001), and in stage IV gastric cancer vs. stage I patients (p = 0.037). The activation index was higher in all gastric cancer cases compared to control (p = 0.001).

Conclusion. All patients with gastric adenocarcinoma, irrespective of the stage, revealed changes in the monocyte chemiluminescence activity, i.e. a longer time to maximum in spontaneous chemiluminescence and larger area under the curve of spontaneous and induced chemiluminescence, the activation index. Maximal monocyte spontaneous chemiluminescence intensity diminished in stage IV gastric cancer compared to the control cohort. Immune activity reflected in monocyte chemiluminescence correlates with the stage of gastric adenocarcinoma.
Using a Delphi Technique to Define a Feedback Culture in Graduate Medical Education
Authors: Page Cristen P. , Baker Hannah M. , Myerholtz Linda
Published: June 2021

Background and Objectives: Experts in medical education hypothesize that programs with a robust culture of feedback foster learning and growth for learners and educators, yet the literature shows no consensus for what defines a feedback culture in graduate medical education.
Methods: Using a two-round, modified Delphi technique in summer and fall of 2019, the authors asked a panel of experts to identify essential elements to a feedback culture. The research team compiled a list of experts and a list of 29 descriptors of a highly functioning feedback culture. Experts rated the items as an essential, compatible, or not important aspect of a highly functioning culture of feedback. Researchers set a minimum threshold of 80% agreement and used comments from panelists to revise elements that did not meet agreement during round one. Experts then rerated the elements using information on their initial ratings, aggregate panelist ratings, and comments from all panelists.
Results: The response rates from our panel of experts were 68% (17/25) for round one and 88% (15/17) for round two. Seventeen elements were rated as essential to a feedback culture.
Conclusions: An expert panel endorsed essential elements that can be used to assess feedback culture in graduate medical education programs.

Authors: Johnson Jerica , Stromberg David , Willims Byrch , Greenberg Nina , Myers Orrin
Published: June 2021

Background and Objectives: Point-of-care ultrasound (POCUS) is increasingly being incorporated into family medicine residency training. Attitudes towards POCUS among family medicine residents (FMRs) are largely unknown, and confidence levels with performing and interpreting POCUS exams are also unknown among this group of learners. Our aim was to evaluate FMRs’ attitudes and confidence levels before and after the implementation of a new POCUS curriculum.
Methods: Study participants included FMRs in all postgraduate years (ie, PGY1-PGY3) at the University of New Mexico (UNM) Family Medicine Residency Program. Our intervention was a yearlong implementation of a new POCUS curriculum based on the American Academy of Family Physicians POCUS curriculum guidelines. Our interventions included hands-on training sessions for both FMRs and faculty along with a resource website. We assessed attitudes and confidence levels with various POCUS exams using a pre- and postintervention survey.
Results: Overall, FMRs felt significantly more confident in their ability to perform and interpret a point-of-care ultrasound after the implementation of POCUS curriculum. There was no significant difference in participants’ expectations of their use of POCUS during or after residency.
Conclusions: Overall, this study provides evidence that the implementation of a POCUS curriculum that includes hands-on and didactic training is associated with increased confidence in utilizing POCUS among FMRs.
Simone de Beauvoir e a dimensão metafísica da existência: uma análise de 'A convidada' | Simone de Beauvoir and the metaphysical dimension of existence: an analysis of 'She came to stay'
Authors: Andrade Josiana Barbosa
Published: June 2021

A convidada [1943], longe de ser uma aplicação de ideias abstratas, foi um dos romances que inaugurou o que Merleau-Ponty nomeou de “romance metafísico”. Não há nele uma perspectiva, mas perspectivas; uma consciência ubíqua que conduz o drama, mas consciências situadas no espaço, no tempo e na história. À vista disso, buscaremos mostrar, ao longo deste estudo, o que caracteriza a dimensão metafísica da existência que constitui o romance de Simone de Beauvoir, por meio da hipótese de que essa dimensão é o que o define, essencialmente. Para isso, utilizaremos tanto as observações da filósofa, elaboradas em sua autobiografia e alguns de seus ensaios, quanto a análise de Merleau-Ponty a respeito do tema.

Meninas Desamparadas? A Pastoral da Mulher Marginalizada e o nascimento do movimento brasileiro de prostitutas | Helpless Girls? The Pastoral da Mulher Marginalizada and the birth of the Brazilian prostitutes’ movement
Authors: Weeks Meg
Published: June 2021

ResumoEste artigo aborda o nascimento do movimento de prostitutas no Brasil partindo de uma análise da Pastoral da Mulher Marginalizada, uma iniciativa da Igreja Católica que realizou um trabalho assistencialista e de conscientização política com mulheres prostitutas no Brasil a partir da década de 1970. Minha pesquisa examina as tensões entre as participantes e os agentes da Pastoral que deram origem a um movimento autônomo de profissionais do sexo em meados da década de 1980. Eu argumento que a Rede Brasileira de Prostitutas (RBP) foi influenciada não só pelo clima político da democratização, mas também pelo discurso de autoestima e do valor intrínseco do indivíduo pregado pela Pastoral. Finalmente, eu considero o Primeiro Encontro Nacional de Prostitutas, realizado em 1987, destacando como a RBP acabou rejeitando o tropo da prostituta-como-vítima e as crenças abolicionistas do ramo progressista da Igreja.Palavras-chave: Prostituição. Igreja Católica. Movimentos sociais. Abertura política. AbstractThis article examines the birth of the Brazilian sex-worker movement by foregrounding an analysis of the Pastoral da Mulher Marginalizada, a ministry of the Catholic Church that conducted outreach and political consciousness-raising among prostitutes in Brazil starting in the 1970s. My research explores the tensions between ministry participants and agents that eventually led to the founding of an autonomous movement of sex workers in the mid-1980s. I argue that the Rede Brasileira de Prostitutas (RBP) was influenced not only by the political climate of Brazil’s democratization process, but also by the discourse of self-esteem and the intrinsic value of the individual espoused by the Pastoral. Finally, I consider the Primeiro Encontro Nacional de Prostitutas, held in 1987, highlighting how the RBP came to the trope of the prostitute-as-victim and the abolitionist beliefs of the progressive branch of the Catholic Church.Keywords: Prostitution.

O crânio-celebridade: Antônio Conselheiro e o fracasso da degeneração racial | The infamous skull: Antônio Conselheiro and the failure of racial degeneration
Authors: Fraga Isabela
Published: June 2021

ResumoEste ensaio examina a sobrevida textual de uma cabeça — a de Antônio Vicente Mendes Maciel, o Antônio Conselheiro (1830-1897), a partir de sua morte na Guerra de Canudos (1896-1897). Traçam-se as figurações do crânio de Conselheiro na imprensa brasileira do fim do século XIX e nos trabalhos do médico legista Raimundo Nina Rodrigues e do engenheiro e escritor Euclides da Cunha. Embora ambos esperassem que o crânio de Conselheiro apresentasse evidências físicas de degeneração racial, as observações craniométricas de Nina Rodrigues revelaram um crânio normal. Argumenta-se que esse fracasso da aproximação materialista à psique humana deu proeminência a explicações sociológicas para o fenômeno de Canudos, além de levantar questões sobre visibilidade, raça e racismo científico na virada do século XX e no mundo contemporâneo.Palavras-chave: Raça. Psiquiatria. Guerra de Canudos. Antropologia criminal. AbstractThis essay examines the textual afterlife of a head—that of Antônio Vicente Mendes Maciel (Antônio Conselheiro [1830-1897]), after his death in the Canudos War (1896-1897). It traces figurations of Conselheiro’s skull in the late nineteenth-century Brazilian press and in the works of Raimundo Nina Rodrigues and Euclides da Cunha. Although these two social scientists expected Conselheiro’s skull to display physical evidence of racial degeneration, Nina Rodrigues’s craniometric measurements and observations revealed a perfectly normal skull. It is argued that this failure of a materialist approach to the human psyche allowed a stronger reliance on sociological explanations for the Canudos phenomenon that opens up questions on scientific racism and the visibility of race in the turn of the twentieth century and in contemporary times.Keywords: Race.

Teoria Mimética e vulnerabilidade do sujeito – Ou: René Girard, Sigmund Freud e Oswald de Andrade | Mimetic Theory and the vulnerability of the subject – Or: René Girard, Sigmund Freud and Oswald de Andrade
Authors: Rocha João Cezar De Castro
Published: June 2021

ResumoEsse artigo propõe um contraponto entre a teoria mimética de René Girard, as considerações freudianas sobre sujeito e a obra de Oswald de Andrade. O sujeito mimético coincide com o sujeito antropofágico oswaldiano, pois idêntica divisa poderia defini-los, transformando o alheio em próprio, e transformá-lo a tal ponto que as fronteiras entre o eu e o outro se confundem. Cada um a seu modo, Oswald de Andrade e René Girard assimilaram criativamente a lição freudiana, especialmente a leitura de Totem e Tabu (1913). O pensador e poeta brasileiro inverteu os termos da equação, descobrindo “a transformação permanente do Tabu em totem”.Palavras-chave: Teoria Mimética Girardiana. Sujeito Mimético. Antropofagia em Oswald de Andrade. Totem e Tabu. AbstractThis article proposes a comparison among René Girard’s mimetic theory, Freudian assumptions on the self and Oswald de Andrade’s work. The mimetic self coincides with the Oswaldian anthropophagic subject, since the identical division could define them, transforming the other in the self, and transform it in such a way that the limits between the self and the other can be confused. Each one in his own way, Oswald de Andrade and René Girard assimilated creatively Freud’s lesson, especially the reading of Totem and Taboo (1913). The thinker and Brazilian poet inverted the terms in the formula, descovering ‘the permanent transformation of the Taboo in totem.’Keywords: Girardian Mimetic Theory. Mimetic Self.

We at SEA believe that the pandemic has a granularity of meta, non-linear narratives that become useful in making sense of the relational complexities of the pandemic and society. Thus, we set out to collect stories of fears, joys, agilities, fragilities, friendships, networks, collectives, home, work, infrastructures, entrepreneurship, privileges, marginalizations, migrations, desperation, gender, equity, etc. The glossary as a method became useful to reflect on this granularity of experiences and account for slippages during these times. These spatio-temporal stories, when read together or as individual instances produce a new sense of the emergent contemporary. This framework also allows us to speculate on the kind of world we will inhabit once the storm has passed.

We draw on multiple readings to bring out the nuances and patterns of social life produced in a pandemic. This we hope would allow us to collectively reflect on the restructured ideas of the self, the collective, society, space, and time.

The pandemic created a series of new offences and crimes that were not seen before, from sneezing to black marketeering, the idea of crime and society changed with the changing health crisis.

Published: June 2021

Background: Data on influenza incidence during pregnancy in China are
limited. Methods: From October 2015–September 2018, we conducted active
surveillance for acute respiratory illness (ARI) among women during
pregnancy. Nurses conducted twice weekly phone and text message
follow-up upon enrollment until delivery to identify new episodes of
ARI. Nasal and throat swabs were collected ≤10 days from illness onset
to detect influenza. Results: In total, we enrolled 18,724 pregnant
women median aged 28yo, 37% in first trimester, 48% in second
trimester and 15% in third trimester, with 7 self-reported vaccination
during pregnancy. In the 18-week epidemic period during October
2015–September 2016, influenza incidence was 0.7/100 person-months
(95% CI:0.5–0.9). In the 29-week epidemic during October
2016–September 2017, influenza incidence was 1.0/100 person-months
(95% CI:0.8–1.2). In the 11-week epidemic period during October
2017–September 2018, influenza incidence was 2.1/100 person-months
(95% CI:1.9–2.4). Influenza incidence was similar by trimester. More
than half of the total influenza illnesses had no elevated temperature
and cough. Most influenza-associated ARIs were mild, and
<5.1% required hospitalization. Conclusions: Influenza
illness in all trimesters of pregnancy was common. These data may help
inform decisions regarding the use of influenza vaccine to prevent
influenza during pregnancy.
Beta-2 microglobulin removal with postdilution online hemodiafiltration - comparison of three different dialysis membranes
Authors: Nenadovic Marko , Petrovic Dejan , Trbojevic-Stankovic Jasna
Published: June 2021

Introduction. Accumulation of middle molecular weight uremic toxins causes various complications in chronic hemodialysis (HD) patients. Postdilution online hemodiafiltration (OL-HDF) efficiently removes these molecules. This study aimed to assess the effectiveness of three different dialysis membranes in removing ?2- microglobulin (?2m) within a single session of postdilution OL-HDF. Method. A prospective single-center study was carried out in 30 patients (23 males and seven females, average age 54.87 ? 11.66 years, time on dialysis 4.95 ? 5.4 years) on maintenance HD. Each patient was followed for three consecutive weeks on OL-HDF with three different dialyzers: DiacapPro 19H, FX CorDiax 800, and Elisio 21H, randomly switched weekly. The reduction ratios (RR) of ?2m and albumin were compared individually. The results were analyzed with the Kolmogorov?Smirnov test, ANOVA, and the Kruskal?Wallis test. Results. The average convective volume for all patients was 21.38 ? 2.97 L/session. ?2-m RR was 70.86 ? 6.87%, 74.69 ? 6.51%, and 70.04 ? 9.37% with Diacap Pro 19H, FX CorDiax 800 and Elisio 21H membrane, respectively (p = 0.054). Albumin RR was 6.20 ? 2.12% with Diacap Pro 19H membrane, 6.01 ? 2.97% with FX CorDiax 800 membrane, and 6.46 ? 2.91% with Elisio 21H membrane (p = 0.812). Albumin loss was < 4 g/dialysis treatment for all membranes. Conclusion. All investigated membranes effectively remove ?2-m in postdilution OL-HDF with a tolerable albumin loss. The highest ?2-m RR was determined for FX CorDiax 800 membrane, but with no statistically significant difference.
Interpersonal Function of Joe Biden’s Victory Speech (Systemic Functional Linguistics View)
Authors: Darong Hieronimus Canggung
Published: June 2021

Text analysis was mainly concerned with the ideational function and textual function. Besides, macro aspect has been regarded as the most text structure examined in previous studies.  Regardless of those three aspects, this study focused on the interpersonal function analysis of political speech text, by taking an example of Joe Biden’s victory speech. The purposed theory namely Systemic Functional Linguistics theory (SFL) was then applied to analyze the text. The analysis was conducted by modifying the speech text into clauses which were subsequently analyzed in accordance with the goal of the analysis. Data analysis revealed that the speech established an intimate relationship and a close distance with the audience. As such, the speaker enables to gain support and exchange information through the use of linguistics resources namely declarative clause in the mood structure, modality, and pronoun "we". As a conclusion, different use of mood, modality, and personal pronouns might determine the different level of interpersonal function of a text. This study has a great impact on language teaching and learning in terms of maintaining social relationships and exchanging meanings between teachers and students by taking into account the link between linguistic resources and the nature of texts.

Published: June 2021

This study aims to analyze the role of job satisfaction in mediating the relationship between emotional intelligence and intellectual intelligence on the performance of the high school teachers. This study uses a research design with an associative quantitative approach. Data was collected through documentation and online questionnaires. This study used a sample of 39 respondents with the determination of the sample size using the saturated sample formula. Partial least square is applied to examine the relationship between teacher performance, job satisfaction, emotional intelligence and intellectual intelligence. The results of this study indicate that of the seven hypotheses developed there are two accepted hypotheses, that is, for the effect of emotional intelligence on job satisfaction, it is obtained that the results of a significant effect and the influence of spiritual intelligence on teacher performance are also obtained significant results. Meanwhile, the other 5 hypotheses developed were not significant. Through the findings of this study, it is hoped that it can provide additional information for various parties, especially the school, to pay attention to the factors that affect teacher performance and job satisfaction, so that teachers gain comfort and confidence to continue to improve their performance in implementing learning in schools.

Published: June 2021

This study aimed to investigate the kinds of 21st century skills (4Cs) in English literacy activities. The design of this research was descriptive qualitative. The subjects of this research were 120 students and 3 teachers in this school. The techniques of data collection were observation, interview, note taking, document analysis and documentation. The finding showed that there were five English literacy activities implemented in this school namely, reading response journal, news reading program, guiding object commentary, travel itinerary writing and cooperative literacy program. In the implementation of those English literacy activities, the teachers taught the 21st century skills (4Cs). In reading response journal, the 21st century skills taught were critical thinking, collaboration and communication skills. In news reading program and cooperative literacy program, all of those 21st century skills (4Cs) were taught.  In, guiding object commentary, there were three 21st century skills were taught namely critical thinking, creativity and communication skills. At last, there were three skills were taught in travel itinerary writing namely critical thinking, collaboration and creativity skills. In teaching the 21st century skills, the teachers still had challenges in teaching critical thinking, collaboration and communication skills. There was no challenge in teaching creativity skill in English literacy activities. This research was expected to be beneficial for the policymaker, schools, and teachers who had big effort in implementing effective literacy program in schools. Those activities and ways of teaching the 21st century skills could be adopted in order to enhance the level of literacy program.

Published: June 2021

Waste cooking oil has high Free Fatty Acid (FFA). It affected on decreasing a biodiesel production. FFA reduction is one of important processes in biodiesel production from waste cooking oil. Thus, this study aimed to examine the optimum condition in FFA reduction. The process is assisted by using ultrasonic irradiation on acid esterification. Variables of the process are acid concentration, molar ratio of methanol and oil, and irradiation time. Meanwhile temperature irradiation on 45oC is a control variable. Process optimization is conducted by Response Surface Methodology (RSM) with Central Composite Design (CCD). The optimum conditions of response were 7.22:1 (methanol to oil molar ratio), 0.92% wt H2SO4, 26.04 minutes (irradiation time), and 45oC (irradiation temperature). Ultrasonic system reduced FFA significantly compared to conventional method.
Motivations among Special Education Students and their Parents for Switching to an Online School: Survey Responses and Emergent Themes
Authors: Tonks DeLaina , Kimmons Royce , Mason Stacie L.
Published: June 2021

Research focusing on the experiences of special education students in online K–12 schools is scant despite growing numbers of enrollments. This study utilized an emailed survey to understand the motivations and experiences of a group of special education students (n = 30) and their parents (n = 29) while enrolled in an online K–12 school in the U.S. Responses indicated that the three most compelling reasons for choosing the school were flexibility, previous poor fit, and teacher availability. Qualitative analysis of open-ended responses produced two major themes—prior experiences and affordances of the learning environment—with sub-themes related to bullying, personnel, academics, disabilities and accommodations, health considerations, lack of support, self-determination, and the where, when, and how of online learning. These findings may help policy makers enact policies and online educators adapt their approach to better meet the needs of K–12 students with special needs.

Authors: Latheef Zahir Ibrahim , Robinson Robert , Smith Sedef
Published: June 2021

Readiness for online learning has been established as a key component of student success in online classes. In addition, the COVID-19 pandemic has underscored how vital being prepared for online can be. This paper highlights an orientation technique widely used in the business field, namely Realistic Job Preview (RJP), as a method to prepare students for what online learning might be like. Our research proposes an RJP would help students adapt to their new role as online learners. For the purposes of this study, we developed a video providing a realistic preview of online learning following recommendations from RJP research. We then conducted a mixed methods study to examine student perceptions of our realistic preview video and an online readiness self-assessment. Overall, our findings provide strong evidence for the use of RJP as a strategy to improve student readiness for online learning.
Professional Development and ICT: English Language Teachers’ Voices
Authors: Kohnke Lucas
Published: June 2021

While technology use is becoming increasingly common in education, teachers remain reluctant to use it and hesitant on how best to incorporate it into their teaching and practice.  There is a strong demand from institutions for English language teachers to cope with the changing landscape of teaching in the 21st century.  This explorative study investigated Hong Kong tertiary teachers’ beliefs on continuing professional development activities to enhance their teaching.  The study had a two-phase research design, with an initial questionnaire (N = 58) followed by semistructured interviews (N = 12) to unpack the participants’ hidden voices.  The findings illustrated that most teachers are enthusiastic about professional development activities, though there is a misalignment between what universities value and reward and what teachers see as most beneficial for enhancing their teaching practices.  The results suggested that professional development activities should focus on sharing good teaching practice (e.g., informal chats, mentoring) within universities rather than on rewarding attending conferences and on-off, nonintegrated workshops.
The Orthodox Church and the Transhumanist Ideas on Overcoming Death
Authors: Cira Călin Emilian
Published: June 2021

For mankind, death is a great mystery. Throughout history, numerous opinions about death have been issued, in search of its cause, and many ways and means to defeat it have been attempted. Recent scientific developments have not stayed back from the challenge of studying biological life and attempting technological solutions to help people reach an advanced age that is not subject to decrepitude, and perhaps even to achieve immortality. This idea is also present in the transhumanist movement that aims to change human nature through technology and supports the possibility of obtaining a lifespan capable of far exceed the current one. In this text, we attempt to give a possible answer to this transhumanist challenge from an orthodox Christian point of view.

The studies were performed for four consecutive years (2016–2019) at the Fruit Growing Research Station (North-East part of Romania), using eleven sweet cherry genotypes as research material. Five of them are new cherry cultivars – ‘Cătălina’, ‘Andreiaş’, ‘Maria’, ‘George’, and ‘Margonia’ – obtained by means of controlled hybridization or open pollination, and six of them are their progenitors (‘Van’, ‘Boambe de Cotnari’, ‘Stella’, ‘Fromm’, ‘Ciliegia di Ottobre’, and the ‘HC 27/4’ hybrid). The experiment compared the traits of new cultivars with those of their progenitors. The following traits were evaluated: tree vigor, frost damage, the phenological stages, and the physical and chemical traits of the fruit. The highest values concerning the fruit's weight have been recorded for ‘Andreiaş’ (10.0 g) and ‘Maria’ (7.6 g), the content of soluble substance was between 16.6 and 19.5°Brix, the titratable acidity was between 0.413 and 0.675 mg malic acid·100 mL−1 juice, and the total content of polyphenols was recorded with values between 268.00 and 488.75 mg GAE·100 mL−1 of fresh juice. The new cultivars have mostly superior traits, especially frost damages, productivity, fruit quality, and fruit's cracking percentage compared with their parental genotypes.

Published: June 2021

In the territory of the Slovak Republic, the transportation of goods from east to west is carried out in Eastern Slovak Trasnsshipment. The transportation of goods in direct international rail transport between the Slovak Republic, the Russian Federation, and Ukraine is carried out through the border crossing points Čierna nad Tisou – Čop and Maťovce – Užhorod. These border crossing points are places on a broad-gauge and standard-gauge railway, wherer loading, unloading, and reloading of goods from wider gauge wagons to narrower gauge wagons shall be carried out. There is also a shift of transport mode from SMGS to CIM and other services associated with this transport. An important document affecting the functioning of the single railway market is the Customs Code of the European Union and its provisions. It should be noted that the Common Economic Area of the European Union is also the common customs area of all the Member States. In the case of the cross-border international rail transport organisation, there are no control services due to the customs clearance of the goods. For carriers and customers, this means easier process organisation thanks to the provisions of the Customs Code.
