Leitura Literária Infantil e o Papel do Bibliotecário Mediador
Authors: Pinheiro Mariza Inês da Silva , Jacinto Vera Lúcia Gaparin
Published: September 2021

Tendo por objeto de estudo as histórias infantis do acervo da Biblioteca da “Escola Estadual Professora Renilda Silva Moraes” da cidade de Rondonópolis – MT a pesquisa buscou identificar a moral e a narrativa das histórias e verificar se as literaturas são lidas pela bibliotecária antes de sua disponibilização. Foram analisadas 100 obras escolhidas aleatoriamente no acervo no período de abril a junho de 2015 e teve dois indicadores para análise: o nível de compreensão e a moral da história. Os resultados mostram que que o nível de compreensão das histórias foi de fácil entendimento, que todas as obras apresentam uma moral explícita ou implícita, demonstrando algumas mensagens de amor, amizade e respeito à natureza e que a bibliotecária lê as obras no momento do tombamento das literaturas. Considera-se que dar às crianças a oportunidade de conhecer uma obra literária pode contribuir para a construção do seu gosto pela leitura. Conclui-se que tão importante quanto, saber se uma obra infantil apresenta, ou não, uma “moral da história” é reafirmação da ideia de que os livros são um bom caminho para ampliar o universo cultural dos futuros leitores, oportunizando entrar em contato com situações desconhecidas e/ou diferentes.

Motivators for learners of languages other than English in college elective courses in a monolingual social setting
Authors: Huang Shu-Chen
Published: September 2021

Guided by the Second Language Motivational Self System (L2MSS) framework, this study examined to what extent the three L2MSS components of ideal self, ought-to self, and learning experience described the motivation of learners who chose to enroll in college elective courses of modern languages other than English (LOTEs) in the monolingual social setting of Taiwan. Questionnaire surveys were conducted at the end of two consecutive semesters and learners were interviewed. Triangulation of survey and interview data suggested that a positive learning experience was the strongest factor in motivating effort. Although some classroom factors were known, others worth further exploration in instructional settings were pointed out. The ought-to L2 self was found to be an insignificant predictor with questionable validity. Instead, academic responsibility and instrumentality proved more relevant factors in LOTE. Results on ideal self were less straightforward, suggesting that the ideal self for LOTEs may be qualitatively different from the English ideal self. Comparisons of data sets across time and learner groups indicated motivation did not change over time. By considering major L2MSS components and related constructs together, this study uncovered their relative adequacy in explaining LOTE motivation and suggested possible new perspectives for studying motivation in instructed LOTE acquisition.
Health Literacy, The Second Wave of Covid-19, and Our Enigmatic Intuition!
Authors: Bhattacharya Sudip , Saleem Sheikh Mohd
Published: September 2021

Health literacy refers, broadly, to the ability of individuals to “gain access to, understand, and use information in ways which promote and maintain good health”. Health literacy enhances the self-efficacy of people to adapt recommended
preventive behaviors, such as vaccination against vaccine-preventable diseases or the use of a helmet while driving a motorcycle. Health literacy is a part of health promotion under preventive medicine, which is mostly a neglected
area, especially in the context of India. When we follow the business model (U.S.) of health care in India, instead of the welfare model, it is quite natural that when a disaster-like situation arises, the health system collapses
like a fragile object.

A Survey in West Java shows that Mindi (Melia azederach Linn.) is frequently found on the community forest lands as part of a mixed cropping system. These community forest lands have a potential to support food security. Soybean is an important food crop as source of protein in Indonesian. This study aimed to observe the growth of Mindi and soybean in an agroforestry system. This study used a split plot design which consists of two factors. The main factors was Mindi which planted using shade and without shade and the second factors are soybean variety (Argomulyo, Anjasmoro, Grobogan, and Wilis) using four replication. The results showed that differences of Mindi cropping method did not significantly affect the Mindi growth (height and diameter) which has been observed for three months. Wilis had the highest survival rate than others varieties. Both factor shade and varieties giving a very significant effect on the kedelai height at the 3-7 MST age. In addition, it's also very significantly affected the number of leaves trifoleat at the age of 3, 4, and 5 MST. Soybean production in Mindi agroforestry system gaves the higher yield than monoculture system at three months age.Key words: Agroforestry, mindi, soybeans, shade, variety.

Forest land conversion into oil palm plantation causes drastic ecological changes which influence various species in the ecosystem. Arthropoda, as one of the components of biodiversity, has important roles as herbivore, predator and parasitoid, and detritivore. This research was conducted in village of Runtu, Subdistrict of Arut Selatan, District of Kotawaringin Barat, the province of Central Kalimantan. Techniques of Arthropoda sample collection were pitfall trap, malaise trap, and sweep net conducted in two ecosystems. The two ecosystems were ecotone (transition between forest and oil palm plantation) and oil palm plantation. Research results showed that forest existence could increase the abundance of arthropoda. Abundance of Arthropoda in ecotone ecosystem was higher as compared to that in oil palm plantation. Populations of predator and parasitoid Arthropoda were higher in ecotone ecosystem.Key words: Arthropoda, detritivore, herbivore, oil palm plantation, predator, parasitoid
