Ethnomathematics: Exploration Of Jubata Dayak Kanayatn Dance Sanggar Padagi Raya
Full text linkThis study aims to describe the mathematical elements contained in the Jubata Dayak Kanayatn Dance at the Padagi Raya Studio. This study will not only contribute to cultural preservation, but also provide new insights into ethnomathematics studies and increase public awareness of mathematics in the context of local culture. This study is expected to be a reference for further research, as well as offer alternative solutions in mathematics learning that are more contextual and relevant to the culture of the community. The method used is qualitative research with an ethnographic approach, involving observation, semi-structured interviews, and documentation to collect data from three informants. The results of the study indicate that the Jubata Dance contains various fundamental mathematical activities, such as calculating, measuring, designing, determining locations, playing, and explaining. The mathematical elements identified in this dance include angles, geometric transformations, flat shapes, and spatial shapes. Each dance movement has a mathematical meaning that can be analyzed, such as the angular patterns formed in the movement, as well as the use of geometric formations that show the relationship between dance and mathematics. This study fills the gap in previous studies on ethnomathematics in Jubata Dance and provides new insights into understanding the relationship between culture and mathematics. The conclusion of this study is that Jubata Dance is not only a cultural expression, but also contains mathematical elements that can improve the understanding of the community, especially students, about mathematical elements in the context of local culture. This study is expected to be a reference for further studies and provide alternative solutions in learning mathematics that are more contextual and relevant to everyday life. By integrating cultural elements into education, it is hoped that students can more easily understand mathematical elements and see their relevance in their daily lives, as well as increase their interest in learning the subjectEtnomatematika: Eksplorasi Tari Jubata Dayak Kanayatn Sanggar Padagi RayaABSTRAKPenelitian ini bertujuan untuk mendeskripsikan unsur-unsur matematika yang terdapat dalam Tari Jubata Dayak Kanayatn pada Sanggar Padagi Raya.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Kajian Analisis Geometri pada Rumah Adat “Dori Mpulor” Sebagai Dasar Pengembangan Pembelajaran Matematika Berbasis Etnomatematika
Full text linkThis research aims to examine the geometric concepts present in the traditional house "Dori Mpulor" as a basis for developing ethnomathematics-based mathematics learning to support the Merdeka Curriculum. The study employed a qualitative descriptive method with an ethnographic approach. Data collection techniques included observation, interviews, and documentation. The analysis of the data was performed using qualitative techniques, including data reduction, data display, and conclusion drawing. The findings revealed that there are geometric concepts in the structure of the Dori Mpulor Traditional House, which include the positioning of two lines on a plane (parallel lines, intersecting lines), angles (opposite angles, supplementary angles, right angles, and acute angles), gradients, congruency (line segments, angles, polygons), polygon similarity, triangles (equilateral and right triangles), circles, cylinders, parallelograms, and trapezoids. In conclusion, the study of geometric concepts in the Dori Mpulor Traditional House can be implemented as learning material, giving educators the freedom to create quality learning experiences tailored to students\u27 needs within a real context, so that students gain enjoyable and meaningful learning experiences.

The Influence of Self-efficacy and Learning Motivation on the Numeracy Literacy Ability of Junior High School Students
Full text linkThis numeracy literacy ability is important in mathematics learning. Self-efficacy and motivation to learn play an important role in improving students' numeracy literacy skills. The purpose of the study was to determine the influence between self-efficacy and learning motivation on numeracy literacy skills in SMP Negeri 2 Ngabang. This study uses a quantitative research method. This research was carried out at SMP Negeri 2 Ngabang with 9 classes totaling 247 students who were the subjects of the research.

Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
