An Evaluation of the Flipped-Learning Pedagogical Approach
Authors: Chendri Devender 
Published: October 2021

In recent years the emerging possibilities in the education system are flexibility (Nuhoğlu et al., 2020) and self-paced learning (Priscila, 2020). The flexibility of studying anywhere and anytime can provide opportunities for learners to achieve their educational goals. A self-paced and customized learning environment could enhance the learning experience of the students. This research evaluates flipped-learning pedagogical approaches for year 13 Maths students. Quantitative and qualitative data collection methods track and monitor students’ academic outcomes. The findings suggest that flipped-learning improved students’ academic achievement and progress. Additionally, students who missed the lessons could understand the concept and complete learning activities before coming to the next lesson. A flipped-learning approach has encouraged the students to make them responsible for their learning, bringing questions to the classroom to extend their conceptual understanding, and develop mathematical reasoning and thinking skills.
Corps à l’épreuve
Authors: Robinaud Marion 
Published: October 2021

Cet article a pour but de mettre en question les corps dans les situations de rencontre entre missionnaires et Nord-Amérindiens. Ce contexte de rencontre sera considéré, non pas comme étant limité à la période coloniale historique, mais plutôt comme se poursuivant jusqu’au xxe siècle. À partir d’archives et de discours de religieuses missionnaires recueillis lors d’enquêtes de terrain, l’auteure examine la fabrication des corps dans ce contexte et analyse les moyens par lesquels les rapports à l’altérité se construisent à travers les corps, de part et d’autre, entre situations de confrontation, de mise en conformité et de persistance.
L’expérience scolaire des enfants rwandais élevés par des femmes cheffes de ménage
Authors: Narame Ernestine 
Published: October 2021

Au Rwanda, plusieurs rapports gouvernementaux montrent que 32 % des familles sont dirigées par des femmes cheffes de ménage. La situation de cette « nouvelle catégorie sociale particulière » est difficile en raison des charges parentales qui incombent à ces femmes, des responsabilités familiales qu’elles cumulent et qui sont considérées comme tabou, et de la pauvreté (43,8 % de ces ménages sont pauvres). Du fait des conditions matérielles peu propices à la réussite scolaire, la scolarisation des enfants de FCM comporte d’énormes défis.
Partant de notre recherche doctorale sur l’expérience scolaire de 1 838 élèves en 6e année du primaire des écoles publiques de Kigali, cet article porte sur l’expérience scolaire des 314 élèves de cet échantillon éduqués par des femmes cheffes de ménage. Utilisant les données quantitatives issues d’un questionnaire, les données qualitatives tirées d’entretiens individuels et collectifs et les commentaires des questionnaires, l’analyse menée documente l’impact du fait d’être élevé par une femme chef de ménage sur la scolarisation de ces enfants, principalement en raison du manque de ressources financières nécessaires à une scolarité réussie. Cependant, notre analyse montre aussi que ces conditions difficiles n’empêchent pas certains jeunes de s’investir dans leur scolarité et de surmonter les difficultés.
Distribution and fractionation of rare earth elements in suspended particulate matter in a coastal river, Southeast China
Authors: Liu Man , Han Guilin 
Published: October 2021

Background
In the river system, the geochemistry of rare earth elements (REEs, a series of elements from La to Lu) in suspended particulate matter (SPM) is generally controlled by rock weathering processes and hydrochemical characteristics, as well as being affected by anthropogenic activities. However, the variations of geochemical characteristics and behaviors of REEs in SPM with a salinity gradient from the inland river to the estuary have been short of a systematic understanding.

Methods
The REE concentrations, Post Archean Australia Shale (PAAS)-normalized REE, La/Yb, La/Sm, and Sm/Yb ratios of SPM were investigated in the Jiulongjiang River, which is a coastal river mainly flowing through granite rocks in Southeast China. The correlation relationships between physicochemical parameters (including water pH, total dissolved solids (TDS), HCO3– concentrations, and the concentrations of major elements of SPM) and PAAS-normalized REE ratios of SPM were analyzed to determine the factors that affect the REE concentration and fractionation of SPM in the different regions of Jiulongjiang River, including the main stream and tributary of Beixi River, Xixi River, Nanxi River, and estuary. Additionally, the Ce, Eu, and Gd anomalies of SPM were estimated.

Results
The average ∑REE concentration of SPM (352 mg/kg) in the granite rock basin was twice higher than the mean value (175 mg/kg) of the world’s rivers. The PAAS-normalized REE ratios of SPM in the main rivers including Beixi River (main stream), Xixi River, and Nanxi River were near due to the same lithologic distribution. In the tributary of Beixi River, the input of low-weathered carbonate minerals which contain very few REE caused the lower REE concentrations of SPM. The PAAS-normalized REE ratios of SPM in the estuary were significantly lower than those in the main rivers, which was mainly attributed to the significant REE removal with the increment of salinity. The enrichment of LREE relative to HREE in SPM increased with decreasing water pH in the main rivers. In the estuary, the preferential removal of dissolved LREE occurred compared to HREE with the increment of salinity. The negative Ce and Eu anomalies of SPM occurred in both the main rivers and estuary region and rare Gd pollution was present in the basin. Additionally, human activities caused the increment of REE concentrations and more negative Ce anomaly at some specific sites, such as dam effect and agricultural pollution.

Conclusions
The REE concentrations and fractionations of SPM in river water mainly depend on lithologic distribution and riverine pH, while they are affected by salinity in the estuary.
Dystocia in a wild Western Tiger Snake (Notechis scutatus occidentalis)
Authors: Cornelis Jari , Lettoof Damian , Lam Lucinda , Loughridge Sam , Aubret Fabien 
Published: October 2021

ABSTRACT
Dystocia in reptiles is the retention of ova or foetuses within the female due to the failure of the female to complete parturition or oviposition. This disorder is commonly observed in captive reptiles, but has rarely been reported in wild reptiles. We observed a large internal obstruction in an adult female Tiger Snake captured as part of an ongoing population study. We failed to palpate out the object in the field, so we took the snake to a veterinary practice for professional assistance. All non-lethal methods of extracting the object were unsuccessful so we euthanised the specimen and post-mortem dissection revealed five mummified stillborn young lodged in a sealed reproductive tract. Reproductive abnormalities are frequent in Tiger Snakes and large proportions of litters can be comprised of unfertilised eggs, fertilised aborted eggs and stillborn young, yet none of these observations ever resulted in dystocia. It is interesting that this observation occurred in a snake from Herdsman Lake, Western Australia, where the Tiger Snake population is subjected to many anthropogenic stressors. We cannot determine what caused this case of dystocia but suspect it may have been caused by some sort of negative effect onset by the quality of the environment.

The study aims to provide knowledge of self-care for patients with COVID 19 and with heart failures. In the United States, between 2011 and 2014, an estimated 6.5 million Americans over the age of 20 had chronic heart failure The estimated prevalence of heart failure in Asia ranges from 1.26% to 6.7%, in Southeast Asian countries from 4.5% to 6.7%. This study used Health education intervention that was carried out for 90 patients with chronic heart failure inpatient treatment at Cardiology Department - Nam Dinh General Hospital. The rate of heart failure in Korea was estimated at 1.53% in 2013. The frequency of heart failure in Korea is expected to double, from 1.60% in 2015 to 3.35% in 2040. By 2040, more than 1.7 million Koreans are expected to have heart failure .In Japan, an estimated 1.0 million patients have heart failure and the number of outpatients with left ventricular dysfunction is expected to gradually increase to 1.3 million by 2030 In China, 4.2 million people suffer from heart failure and 500,000 new cases are diagnosed each year). We perform method of one-group intervention study with before-after comparison. Health education intervention was carried out in 90 patients with chronic heart failure inpatient treatment at Cardiology Department - Nam Dinh General Hospital. Our results show that patients with cardiovascular disease need to be aware that they are a very high risk group for infection as well as serious complications that may occur if they are unfortunately infected with COVID-19. This research finding and recommended healthy foods to support for better health of patients with chronic heart failure in many developing countries. Last but not least, vital roles of nurses in Nam Dinh and Vietnam hospitals have been increasing in recent years in helping patients and help them to gain knowledge for self-care with COVID 19 and with heart failures and practice “Maintenance of care” of patients with chronic heart failure.
Stereotyping and Othering of Non-White Characters in “Harry Potter” Movies
Authors: Adelia Nadia 
Published: October 2021

This thesis focuses on the way the non-white characters, such as Black and Asian, are portrayed in Harry Potter movies. The non-white people are put in the group of unimportant characters. Their characters seem to be portrayed differently compared to the white characters in term of their characterizations. Using film language theory, such as body language and dialogue, I find there are Stereotyping and Othering towards the non-white characters. I analyze the Stereotyping toward non-white characters such as Cho Chang and Kingsley Shacklebolt as the Asian and Black character using the gestures, facial expression, costumes, and dialogues. I also analyze the Othering towards non-white characters such as Centaurs and Dre Head as the non-human characters using the appearance, accents, and costume. Also, the Yule Ball costume for Cho Chang and Patil twins also shows exoticism because of the races of the characters. Keywords: Racism, Stereotyping, Othering, Representation, Fantasy Fiction
Providing Visual Aids (Posters) for English Lesson Grade One in ABC Elementary School
Authors: Limarsono Johanna 
Published: October 2021

This final project is based on the writer’s internship in ABC Elementary School from March 12th to June 8th, 2018. The writer thought that it was a good solution to make and provide posters as the final project because of the problem she found during her internship in ABC Elementary School, that is, students’ lack of English vocabulary. The students seemed they did not want to participate in the English learning because the English book used in class was quite difficult for grade one students. The writer created posters to provide the students learning tools so that the students can follow and participate the teaching-learning process actively. By having interesting posters with their uniqueness (3D poster, removable poster, and etcetera), the students are expected to feel more interested in knowing and learning English vocabulary. These posters can help to support the teaching-learning process. Keywords: Posters, 3D Poster, English Vocabulary, Project

#nofilter: Online Personas and The Negative Impacts of Social Media on Young Adults’ Self-esteem
Authors: Godwin Jessica 
Published: October 2021

My novel #nofilter follows Mia, a photo model who is pretty famous on the social media platform Instagram, as she meets Kyle, her online boyfriend for the first time. In an effort to earn other people’s acceptance, Mia has been building a perfect online persona. However, after meeting Kyle, it is revealed that she is not who she portrays herself to be. As my work revolves on how social media affects someone’s self-esteem, hopefully it can help the readers learn to love themselves and do not depend their self-esteem on others. Specifically, I focus on how Mia maintains an idealized online persona in order to cope with her low self-esteem and earn other people’s acceptance, how the contrast between Mia’s online and real life personas causes her relationship with Kyle to crumble, and how Mia learns to love herself by accepting her weaknesses and acknowledging her positive qualities. For that reason, I use Contingencies of Self-esteem theory by Jennifer Crocker and Connie T. Wole, the Social Comparison theory, and the Presentation of Self in Everyday Life by Erving Goffman. Set in the early years after college, I use New Adult genre and the sub-genre Contemporary Romance to explore Kyle and Mia’s romantic relationship.
