Get PDFKualitas tidur dan aktivitas fisik yang baik dapat meningkatkan daya konsentrasi dan memori belajar pada seseorang, sehingga berkontribusi pada hasil belajar kognitif yang diperoleh siswa. Tujuan penelitian ini adalah mengukur hubungan kualitas tidur dan aktivitas fisik dengan hasil belajar kognitif materi Sistem Koordinasi Manusia. Penelitian ini dilakukan di SMAN 21 Jakarta pada bulan Maret 2018. Metode penelitian yang digunakan adalah metode deskriptif kuantitatif dengan pendekatan cross sectional. Sampel diambil menggunakan simple random sampling sebanyak 125 siswa kelas XI IPA. Instrumen penelitian yang digunakan adalah instrumen tes hasil belajar Sistem Koordinasi Manusia, instrumen Pittsburgh Sleep Quality Index (PSQI) dan instrumen Physical Activity Qustionnaire Adolescents (PAQ-A). Hasil analisis uji prasyarat menunjukkan data terdistribusi normal dan homogen. Hasil perhitungan koefisien korelasi antara kualitas tidur dan hasil belajar kognitif menunjukkan hubungan positif yang signifikan, sedangkan korelasi antara aktivitas fisik dan hasil belajar kognitif menunjukkan hubungan negatif yang signifikan. Dalam penelitian ini, kontribusi kualitas tidur dan aktivitas fisik sebesar 18,6% dalam menentukan hasil belajar kognitif siswa. A good sleep quality and physical activity can increase the concentration and memory of learning in someone, thus contribute to cognitive learning outcomes obtained by students. The purpose of this study was to measure the relationship between sleep quality–physical activity and cognitive learning outcome on Human Coordination System subject. This study was conducted at SMAN 21 Jakarta in March 2018. The study method used the descriptive quantitative method with cross sectional approach. The samples were taken by simple random sampling as many as 125 students of 11th grade students of Science Class. The used instruments were the cognitive learning outcomes test, Pittsburgh Sleep Quality Index (PSQI) and Physical Activity Qustionnaire Adolescents (PAQ-A). The results of correlation coefficient calculation between sleep quality and cognitive learning outcomes showed a significant positive relationship. While the correlation between physical activity and cognitive learning outcomes showed a significant negative relationship. In this study, the contribution of sleep quality and physical activity was 18.6% in determining students' cognitive learning outcomes
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Variations on the Author
Get PDF“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
Development ICARE based digital module integrated with sets approach to digestive system concept in Senior High School
Get PDFThe limitations of learning resources can be felt in several aspects of the quality and quantity, form and types of learning resources available. Meanwhile, learning resources must be available quickly to realize effective learning, allowing students to push themselves to meet independent learning needs. Digital modules continue to be developed by researchers to support the independent learning process. This study aimed to establish teaching products in ICARE-based digital modules integrated with the SETS approach to the digestive system concept in senior high schools. The type of research used is research and development with the 4D model design by Thiagarajan, which consists of 4 stages: define, design, development, and disseminate. The result of the expert assessment ICARE-based digital module received the very feasible category, as the user responses test, the module got a very conceivable category. The Teacher response test got the highest score, with the grammar aspect getting the highest among other elements. This is because the language used in the module is an interactive language. Based on the result, ICARE-based digital modules can be used in the biology learning process, especially in the digestive system
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
Environmental Sensitivity Peserta Didik Terhadap Citizenship Behavior Yang Dimediasi Oleh Intention To Act Peserta Didik
Get PDFThe environment and humans have a reciprocal and interdependent relationship. There is a reciprocal relationship between the environment and humans resulting in environmental problems that will affect the environment and other living things. The main cause of environmental problems is the waning of one's concern and wise behavior towards the environment. This study aims to determine the effect of students environmental sensitivity on citizenship behavior mediated by students intention to act related to the environment. The research method used is a survey method through a causal study which is analyzed by path analysis. The research was conducted at SMAN 14 Jakarta in the odd semester of the 2021/2022 academic year. The result of the calculation of the reliability coefficient of the citizenship behavior instrument is 0.896, environmental sensitivity is 0.909, and the intention to act is 0.916. The results of this study indicate that environmental sensitivity has a direct effect on intention to act significantly, intention to act has a significant direct effect on citizenship behavior, environmental sensitivity has a direct effect on citizenship behavior significantly, and environmental sensitivity has an indirect effect on citizenship behavior through intention to act. act. So that intention to act can mediate between environmental sensitivity and citizenship behavior of students
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
