Hacer comunicación en el sur del sur: El ejercicio periodístico alejado de la capital
Authors: Benítez Luzuriaga Karina
Published: August 2021

El quehacer periodístico implica una serie de rutinas que el hacedor de noticias debe realizar para reconstruir un hecho y -en forma de mensaje- ponerlo a disposición del público lector. Ese contador de historias, además de su preparación académica debe reunir una serie de cualidades, características y habilidades que le permitan ejercer su labor de la mejor manera. Las salas de redacción se constituyen en escenarios donde con el uso de la tecnología se "repiensan" los hechos. El correcto uso del lenguaje e imágenes, la redacción de la nota cumpliendo el manual de estilo o código de ética establecido por el medio son condicionantes. Esa rutinización ha sido analizada en grandes medios. Puede afirmarse que existen patrones comunes; las teorías de los procesos productivos sirven para estudiar las noticias y los actores que las producen. Esa realidad toma otro matiz en diarios de las provincias, esos alejados de las grandes ciudades. Diarios locales con tiraje limitado, con presupuesto económico también limitado. El artículo reflexiona sobre ese proceso de producción de las noticias, a partir de una serie de entrevistas a periodistas de diarios de Machala, una pequeña ciudad, ubicada al sur del Ecuador, donde la realidad no es la misma de la que se vive en la capital.

Authors: Suasnabas Pacheco Lenin Stalin , Rubira Carvache Alexandra Katiuska , Casilla Salazar Ivonne Nathaly , Schreiber Parra María José
Published: August 2021

El objetivo de la investigación es describir el impacto generado en la educación universitaria ecuatoriana por el surgimiento de las Tecnologías de Información y Comunicación (TIC) en la década de los ochentas del siglo XX. Se analizan los retos principales que las TIC plantean a las universidades en la formación de profesionales para nuevos puestos de trabajo y la formación continua. La introducción de las TIC plantea un nuevo paradigma educativo ventajoso dado que, como propuesta inteligente, identifica el flujo de información, incluidos los equipos de red, el almacenamiento de datos, la gestión de datos, entre otros aspectos. Sin embargo, las claves para el cambio de metodología de la enseñanza radicarán en cómo se utilicen estas herramientas. El trabajo de investigación es de tipo documental, desde el nivel descriptivo. Se utilizó la técnica del fichaje para sistematizar los referentes teóricos. Los autores concluyen que, pese a los cambios generados por la introducción de las TIC en la universidad ecuatoriana, esta permanece rezagada en la alfabetización digital. Además, las afectaciones que traen consigo las TIC influyen directamente a la sociedad, bien sea de forma negativa o favorable, repercute en el medio universitario.

Published: August 2021

En el Ecuador, el acceso a las tecnologías de la información y comunicación es un derecho fundamental de todas y todos, no así para ciertos sectores económicos como el caso de las PYME's (Pequeñas y Medianas Empresas). Estas, ven limitadas sus posibilidades de contratar servicios de Cloud Computing, por adolecer el país de una normativa jurídica específica que lo regule. Es necesario acordar un marco contractual debidamente consensuado entre las partes. En la investigación, se enfatiza en temas de contratación del servicio de Cloud Computing, tales como seguridad, confidencialidad de la información, acuerdos de nivel de servicio (SLA) y objetivos de niveles de servicio (SLO) para la prestación de servicio de calidad. Asimismo, se establecen recomendaciones legales al momento de elaborar dicho contrato. Todo ello permite definir las deficiencias existentes en las leyes ecuatorianas con respecto al servicio de Cloud Computing.

Expert Practice for Classrooms
Authors: Ericsson K. Anders
Published: August 2021

How do I do it?
Expert Practice helps you improve
your skills—no matter what it is you're trying to master. There are
three steps you follow in order, and then repeat, repeat, repeat: First,
identify a specific sub-skill that incrementally challenges you.
Second, practice that skill with full effort. Third, seek feedback on
what you could do better.

How does it work?
The opposite of Expert Practice
is mindless practice—just going through the motions without a real goal
in mind, without concentration, and without meaningful feedback on how
you can improve. When you practice like an expert, you make the most of
your practice time. The same three-step process applies whether you want
to become a better trumpet player, a better writer, or a better
student.

WOOP for Classrooms
Authors: Oettingen Gabriele ,   University of Hamburg
Published: August 2021

How do I do it?
In this step-by step writing
activity, you begin by identifying a wish or goal you want to achieve.
Next, you mentally imagine one positive outcome of achieving this goal
and one obstacle that stands in the way. This reflection sets you up for
the final step: making a plan for how you can get around that obstacle.

How does it work?
A common mistake when setting a
goal is to indulge in fantasies about how great life will be after
accomplishing it—without considering what's currently holding us back.
Mentally contrasting your hoped for outcome with an obstacle that stands
in your path is energizing. This prepares you to make a plan for when
and how you'll take action!
Self-Control
Authors: Duckworth Angela ,   CharacterLab
Published: August 2021

Why does self-control matter?

Sometimes, what makes you happy right now isn't good for you in the
long run. For instance, junk food tastes great but isn't healthy.
Self-control powerfully predicts academic and professional achievement,
physical and emotional well-being, positive social relationships, and
financial security.
Social Intelligence
Authors: Prinstein Mitch ,   University of North Carolina at Chapel Hill
Published: August 2021

Why does social intelligence matter?

Social intelligence is as important as IQ when it comes to happiness,
health, and success. Empathetic people are less likely to experience
anxiety, depression, and addictions later in life. They are also more
likely to be hired, promoted, earn more money, and have happier
marriages and better-adjusted children.
A Lesson in Active Learning
Authors: Duckworth Angela ,   CharacterLab
Published: August 2021

Recently, a group of physics professors at Harvard University ran an experiment you should know about.

There were no balls rolling down planks. No springs or pulleys, no magnets, and no electricity. 

What these professors wanted to know was, how can we get students to
learn more? More generally, how do people learn anything—and what gets
in the way?

Years of experience suggested that students learn best when assigned
hands-on laboratory activities, weekly problem sets, in-class
opportunities to discuss material with fellow students, and frequent
short quizzes. This active approach seemed far superior to the more
traditional—and more passive—approach of sage-on-a-stage lectures.

Bragging Backfires
Authors: Duckworth Angela ,   CharacterLab
Published: August 2021

Does everyone in the universe really need to know where your kid is
headed for college this fall?

Even if your child is marching through the front door of a highly
selective university, there isn't much to be gained by announcing this
news publicly.

In fact, there's a lot to be lost.

I say this as a daughter who remembers cringing, literally, when my
dad—upon meeting old friends, new acquaintances, or just innocent
bystanders at the local hardware store—would somehow work into
the conversation an update on one or another of his children's
accomplishments.

In the same column of “nobody needs to know who hasn't asked,”
I'd put your child's SAT scores, their awards, the personal record you
set in your last marathon, and anything else that, by making you or
your progeny look good, makes the person forced to listen to you feel bad.

Since we all know what it's like to be on the receiving end of bragging,
it's always been somewhat of a mystery to me why bragging persists.
Can I or Can’t I?
Authors: Duckworth Angela ,   CharacterLab
Published: August 2021

Sometimes, we quit things because we really don't want to do them
anymore.

For instance, I quit piano when I was still in elementary school because
I didn't enjoy it. I knew I could keep getting better if I tried, but I felt
only joy on the day I knew I would never have to play another note,
and I've had no remorse since.

But very often, we quit things because we don't think we can do them
even if we try.

I quit taking math in college, because some part of me doubted my
ability to succeed beyond multivariable calculus. I loved derivatives
and integrals and everything I was learning at that point—and I
especially loved my math professor, Robin Gottlieb. Yet the idea of
progressing to upper-level courses was terrifying.

Quitting is sometimes the right decision, but in the moment, when we
declare, “I'm done! No more for me!” it can be very difficult to know
whether we're quitting for the right reasons.
Heat Transfer Enhancement of Forced Convection in Horizontal Channel with Heated Block due to Oscillation of Incoming Flow
Authors: Bouttout Abdelouahab
Published: August 2021

The study in question consists to amplify the hydrodynamic and thermal instabilities by imposed pulsation during forced convection of air cooling of nine identical heated blocks simulate electronic components mounted on horizontal channel. The finite volume method has been used to solve the governing equations of unsteady forced convection. This approach uses control volume for velocities that are staggered with respect to those for temperature and pressure. The numerical procedure called SIMPLER is used to handle the pressure-velocity coupling. The results show that the time averaged Nusselt number for each heated block depends on the pulsation frequencies and is always larger than in the steady-state case. The new feature in this work is that we obtained a short band of frequencies which the enhancement of heat transfer of all electronic components is greater than 20 % compared with steady non pulsation flow. In addition, the gain in heat transfer Emax attainted the maximum value for the central blocks. Our numerical results were compared with other investigations and found to agree well with experimental data.

Authors: Heng Pamela Hendra
Published: August 2021

Children with special needs (ABK) are very different from normal children in terms of needs, health, education, teaching, how to give advice and attention. Children with special needs require special treatment because they have developmental disorders and others disorders from children in general (Desiningrum, 2016). In 2015, Indonesia had approximately 4.2 million ABK. Baska and Stambaugh (in Juwono and Kumara, 2011) state that education services in Indonesia are still experiencing difficulties due to the lack of knowledge of teachers about ABK. Sunardi, Yusuf, Gunarhadi, Priyono, and Yeager (2011) state that in Indonesia, almost no changes have been made to accommodate the education program for children with special needs in inclusive schools; there is no difference in teaching strategies for children with special needs (Kurniawati, De Boer, Minnaert, and Mangunsong, 2017; Mangungsong 2014). The Holland Interests Test, the written Learning Style test and the Multiple Intelligence seminar were attended by 42 adolescents, analyzed by psychologists to determine their interests and talents. A psychoeducation approach through the smart parenting seminar "Mengasuh kidz jaman now" attended by 101 parents, teachers and church practitioners, aimed to give an understanding of the characteristics of children with special needs at church X in East Java.

Published: August 2021

Optimization is an effort to ensure patient radiation safety and is the main action in overcoming concerns about CT-Scan radiation exposure. This led to the emergence of various measures to reduce the dose. This study aims to obtain a minimal dose with a high-quality image. Optimization efforts were carried out by the radiology team at Adam Malik Hospital Medan using a 16 slice GE CT-Scan and a water phantom with a diameter of 16 and 32 cm and an image quality questionnaire form. Collected data by observing the head, chest, and abdomen CT-Scan in adult patients (≥15 years). The data taken is the value of CTDI vol and DLP for a year. Then a water phantom scan was carried out with the head protocol using pitch parameters 0.562 and 0.938. The chest and abdomen use pitches of 1.375 and 1.75. The results obtained were evaluated and applied to patients, then filled in the image quality questionnaire scores. The results of CTDI_vol and DLP values with 16 and 32 cm water phantom scans showed a decrease in the dose value; for pitch 0.938, it was 1.6% lower than pitch 0.562, and pitch 1.75 was 1.2% lower, compared to pitch 1.375. For CT head examination using a pitch of 0.963, the CTDI_vol value was 1.5%, and DLP was 2%. For chest using a pitch of 1.75, CTDI_vol values were 1.3% and DLP 2%, while abdominal examination with a pitch of 1.75 obtained CTDI_vol values 1.8% and DLP 1.4%. From these three results, the CTDI_vol and DLP values were higher than the national DRL values. The value obtained is higher than the national DRL due to differences in the phantom test protocol with clinical implementation and the lack of accuracy in using other parameters. Changes in scan parameters are not comprehensive. Obtained a score of 3 in the questionnaire form stating that the radiology doctor can still interpret the image. This study concluded that it could make optimization efforts by changing the pitch parameter by paying attention to other parameters without reducing the quality of the image interpreted by the radiologist.

Analysis of Distributed Radiation Exposure in The Covid-19 Isolation Room in Kraton Re¬gional Hospital, Pekalongan Regency. Since Covid-19 was declared a world pandemic by WHO, isolation rooms have become a place that is often used to deal with pandemics. Radiological examinations or X-rays are used as a supporting examination in the diagnosis of Covid-19. So it is necessary to adjust the Covid protocol in the examination so that there is no transmission of the virus and the effects of unnecessary radiation. Isolation rooms used for radiological examinations of Covid-19 patients need to be reviewed for safety to comply with procedures. The purpose of this paper is to analyze the scattering radiation exposure in the Seruni isolation room of RSUD Kraton, Pekalongan Regency. The data in this paper were taken by measuring the amount of scatter radiation exposure in room B of the isolation room Seruni RSUD Kraton Pekalongan Regency, on February 16, 2021. This measurement was carried out with a water phantom as object with the highest exposure factor for thorax examination, namely 70 kV and 16 mAs and carried out at several points around the water phantom object with a distance of 2 meters from the source. The measurement results of scattered radiation exposure are then compared with the Dose Limit Value (NBD) for the general public of 1 mSv in one year. Analysis of the measure¬ment of scatter radiation exposure in the Seruni isolation room at Kraton Hospital, Pekalongan Regency, still experienced leaks and the exposure value exceeded tolerance. The measurement results in the hallway of the Seruni room are 676 Sv/h, in addition to the radiographer (2 meters on the left side of the phantom) it is 627.12 Sv/h, at a distance of 2 meters the right side of the phantom is 287.04 Sv/h, and a distance of 2 meters in front of the hall phantom of 676 Sv/h. The follow-up that needs to be done to optimize radiation protection is to install at least 3 scattering radiation shields.
Studi Paparan Radiasi pada Pekerja Radiasi Cathlab dengan Menggunakan My Dose Mini sebagai Upaya Keselamatan Radiasi di RSUP Adam Malik Medan

Published: August 2021

Cathlab radiation workers, when performing interventional procedures, are at high risk of the effects of radiation exposure. The risk of radiation exposure is deterministic and stochastic biological effects. Therefore, radiation exposure studies of radiation workers at the cath lab were conducted to determine the value of radiation exposure received. This radiation exposure study was conducted by measuring and recording radiation exposure doses received by radiation workers. Measurements are made when the radiation officer performs the intervention procedure. The research was carried out for one month in the cath lab room of the Adam Malik General Hospital, Medan. The modalities used are GE Medical System Interventional Fluoroscopy and Phillips Allura Xper FD20. The dosimeter used is “my dose mini”, which is placed inside a shield or apron worn by radiation workers. The size of the apron shield used is 0.50 mm Pb at the front and 0.25 mm Pb at the rear. Radiation officers whose radiation exposure dose was measured consisted of 10 doctors, 11 nurses, and one radiographer. Each inspection procedure of each radiation worker has a different distance, time, and shield from the radiation source. The measurement of radiation exposure dose is (1-59 μSv) for doctors, (1-58 μSv) for nurses, and 1 μSv for radiographers. To protect against radiation must pay attention to the factors of time, distance, and shielding. Ways that can do are to avoid being close to radiation sources for too long, keep a space at a safe level from radiation, and use shields such as Pb-coated aprons, use Pb gloves, Pb goggles, and thyroid protectors. The amount of radiation exposure dose received by each radiation worker at the time of measurement is still within the tolerance limit. The Nuclear Energy Regulatory Agency (BAPETEN) regulation, which the International Commission recommends on Radiological Protection (ICRP), is 20 mSv/year. The results of this study are expected to be used as input for improving the quality of service for monitoring radiation exposure doses in the Cathlab and as reference material for further research.

Nurse educators’ reflections on factors that contributed to their resignation at a public nursing college in Johannesburg, South Africa
Authors: Matahela Vhothusa Edward
Published: August 2021

Background and objective: There is a shortage of nurses in the country and worldwide, and the problem is compounded by the resignation of nurse educators. When nurse educators resign, they leave with their expertise and skills, thus compromising the provision of quality teaching and learning in the institution. It is imperative that a study to determine the factors contributing to the resignation of nurse educators be conducted.  The aim of the study was to explore and describe the factors that contributed to the resignation of nurse educators at a Johannesburg nursing college in South Africa. Methods: A qualitative, exploratory, descriptive and contextual research design was used to provide an in-depth description of factors that contributed to nurse educators resigning from a Johannesburg nursing college. Individual semi-structured interviews were conducted with 15 purposively selected nurse educators, using audiotapes until data saturation. Data were analysed by the researcher and an independent coder using the Tesch protocols on thematic analysis. Trustworthiness was achieved using Lincoln and Guba’s strategies.Results: Three themes emerged, namely: experience of an unappreciative working environment; negative influences on the ‘self’ of the nurse educator; and the need for career advancement and professional growth.Conclusions: The provision of quality nursing education to produce nurses will be difficult in the face of nurse educators resigning from their posts. There is a need to implement retention strategies to create an appreciative working context for nurse educators in the institution.
Vascular Flora of Adobe Valley and Surrounding Hills, Mono County, California
Authors: Winitsky Sophie
Published: August 2021

Adobe Valley and the Adobe Hills lie east of the Sierra Nevada in Mono County, California, and are within the Great Basin Floristic Province. The flora of Adobe Valley and the surrounding hills is influenced by the Great Basin Desert to the east, the Sierra Nevada to the west and the northern Mojave Desert to the south. Adobe Valley is surrounded by the Adobe Hills, Benton Range and Glass Mountain region, creating a circular closed basin with many small tributaries feeding into it. This topography contributes to the creation of a rare wetland complex, including alkali meadows, marshes, and lakes at the base of the hills, which represent some of the more botanically interesting terrain in the region. Prior to this study, the wetland complex of Adobe Valley had not been systematically investigated with regard to its botanical diversity. The vegetation types associated with the wetland complex are listed as threatened by the California Natural Diversity Database and face a number of conservation concerns including water pumping, overgrazing, and possible wind energy development. A total of 1525 herbarium specimens were collected within the study area over 59 days in the field from 2016 to 2018. The vascular flora of the Adobe Valley and Hills includes 397 minimum-rank vascular plant taxa, representing 194 genera and 61 families. Six taxa are only known from historical collections, 21 taxa are non-native and 27 taxa have conservation status. The results of the inventory are presented here in an annotated checklist, along with descriptions of vegetation alliances.

Teaching Mathematics: Heuristics Can and Ought to Lead the Way
Authors: Gordon Marshall
Published: August 2021

In contrast to problem-solving procedures that are the “bricks and mortar” of demonstrations in mathematics textbooks, heuristics, defined by Polya as “the study of means and methods of problem solving”, are those mental actions that enable the practitioner to make progress when it is not clear how to solve problems directly. Yet, as essential as heuristic tools are, they tend not to be included in presentations in mathematics textbooks. The overarching problem can be understood in terms of students’ not developing productive means for engaging problems. A few mathematics problems are included to argue for the validity, if not the priority, of the need for the incorporation of heuristics along with problem-solving procedures as standard content in mathematics textbooks.
The Mystery of the Dancing Men
Authors: Kaur Manmohan
Published: August 2021

In this paper I describe an activity based on a 1903 Sherlock Holmes murder mystery, in which a substitution cipher is used to encrypt secret messages. The story provides a fun and interesting way to talk about frequency analysis, and can be used as a segue into mathematical constructs such as modular arithmetic and computation. The activity is accessible to ages twelve and above, and has been successfully used in mathematics outreach and popularization efforts as well as in general education and mathematics courses.
