Identifying the causes of excessive weight gain in early childhood
Full text linkThe growing health hazards associated with obesity and excess weight, particularly in young children, have made efforts to avoid these issues a top priority. By employing a cross-sectional research design, this study seeks to determine the reasons for weight growth in young children. Fifty children served as research subjects. Multivariate analysis was the method of analysis employed. The study's findings indicated a substantial (p <0.05) correlation between early childhood weight gain and variation factors. According to the study's findings, early childhood weight growth was associated with nutrition, parental genetics, and a lack of physical exercise. The growing health hazards associated with obesity and excess weight, particularly in young children, have made efforts to avoid these issues a top priority. This research was conducted in early childhood education and kindergartens in Kediri, East Java. Purposive sampling was used, meaning the sample was selected based on specific considerations, namely those who were overweight or obese. By employing a cross-sectional research design, this study seeks to determine the reasons for weight growth in young children. Fifty children served as research subjects. Multivariate analysis was the method of analysis employed. The results of the study were that the hereditary factor variable obtained a percentage of 56% with a p value of 0.045 which indicates p < 0.05 proving that there is a significant relationship between hereditary factors and weight gain. The dietary pattern variable accounted for the highest percentage, at 62%, with a p-value of 0.023, indicating a p < 0.05, demonstrating a significant relationship between dietary patterns and weight gain in early childhood. The final variable was physical activity, accounting for 54%. The p-value was 0.027, indicating a p < 0.05, indicating a significant relationship between physical activity and weight gain. The conclusion of this study is that the variables of poor dietary management and lack of daily physical activity are factors that have a higher risk of weight gain

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
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
Шеститижнева програма пліометричних тренувань покращує вибухову силу та спритність у професійних спортсменів Східної Яви
No full textThe study purpose was to prove the effectiveness of a plyometric training program in increasing explosive power and agility in professional athletes of East Java.
Materials and methods. This study is a pre-experiment with a research design of One Group Pretest-Posttest. A total of 15 male athletes from athletics and swimming at the Pusat Pendidikan dan Pelatihan Olahraga Pelajar (PPLP) East Java, Indonesia, aged 15–17 years, body mass index (BMI) 18.5–24.0 kg/m², normal blood pressure, normal resting heart rate, voluntarily participated in the study. The plyometric training program (hurdle-box jumps) was carried out for 30 minutes/training session with an intensity of 80-90% HRmax with a frequency of 3x/week for six weeks. Measuring the explosive power of the horizontal leg muscles used the Standing Broad Jump Test, while measurement of the explosive power of the vertical leg muscles used the Digital Jump Meter Test. Measurement of agility used Shuttle Run Test, and explosive power and agility were measured during pre-training and six weeks post-training. Data analysis used the Paired Sample T-Test with a significance level of 5% using the Statistical Package for Social Science (SPSS) version 21 software.
Results. The results of the study showed that there was a significant difference in the average increase in explosive power horizontally, vertically, and agility between pre-training vs. post-training (p ≤ 0.001).
Conclusions. In general, it can be concluded that the plyometric training program (hurdle-box jumps) carried out 3x/week for six weeks effectively increases the explosive power of the horizontal leg muscles, the explosive power of the vertical leg muscles, and increases agility.Мета дослідження полягала в тому, щоб довести ефективність програми пліометричних тренувань у підвищенні вибухової сили та спритності у професійних спортсменів Східної Яви.
Матеріали та методи. Це дослідження є попереднім експериментом з планом попереднього та підсумкового тестування на одній групі. У дослідженні добровільно взяли участь загалом 15 спортсменів чоловічої статі з легкої атлетики та плавання в Pusat Pendidikan dan Pelatihan Olahraga Pelajar (PPLP), Східна Ява, Індонезія, віком 15–17 років, індекс маси тіла (ІМТ) 18,5–24,0 кг/м², нормальний артеріальний тиск, нормальна ЧСС у стані спокою. Програму пліометричних тренувань (стрибки з перешкодами) проводили по 30 хвилин на тренування з інтенсивністю 80–90% максимальної ЧСС (HRmax) з частотою 3 рази на тиждень протягом шести тижнів. Для вимірювання вибухової сили горизонтальних м’язів ніг використовували тест «Стрибок у довжину з місця», тоді як для вимірювання вибухової сили вертикальних м’язів ніг використовували тест «Цифровий вимірювач висоти вертикального стрибка». Для вимірювання спритності використовували тест «Човниковий біг», а вибухову силу та спритність вимірювали в період до початку тренувань та через шість тижнів після тренувань. Для аналізу даних використовували t-критерій Стьюдента для парних вибірок за рівня значущості 5% із застосуванням програмного забезпечення Statistical Package for Social Science (SPSS) версії 21.
Результати. Результати дослідження показали, що існує статистично значуща різниця в середньому збільшенні вибухової сили по горизонталі, вертикалі та спритності між періодами до та після тренувань (p ≤ 0,001).
Висновки. Загалом можна дійти висновку, що програма пліометричних тренувань (стрибки з перешкодами), яку проводять 3 рази на тиждень протягом шести тижнів, ефективно збільшує вибухову силу горизонтальних м’язів ніг, вибухову силу вертикальних м’язів ніг і підвищує спритність
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
