Evaluation of Physicochemical and Phytochemical Profile of Kombucha Based on Goji Berry (Lycium barbarum)
No full textKombucha is traditionally produced using tea; however, it can also be
formulated from a variety of alternative substrates, including fruits, herbs, vegetables,
and spices. This study investigated the use of goji berries (Lycium barbarum) at
varying concentration (1%, 3%, and 5% w/v) as a substrate for kombucha
fermentation. The objective was to evaluate the physicochemical parameters (pH, total
alcohol content, sucrose concentration, total titratable acidity, color intensity, and
total soluble solids) and the levels of key phtochemical compounds (total phenolics,
quercetin, and tannins), across three fermentation time points: day 1, day 7, and day
14. The fermentation process was found to result in a decline in pH, total alcohol,
sucrose, and total soluble solids, alongside an increase in titratable acidity, total
phenolic content, quercetin, and tannin levels. These findings suggest that goji berries
are a suitable for kombucha fermentation, as the observed physicochemical and
phytochemical transformation reflect active metabolic processes by the SCOBY
(Symbiotic Culture of Bacteria and Yeast).112 PagesSkripsi Sarjan

No full text111 HalamanPenelitian ini menggunakan kuantitatif korelasional bertujuan untuk mengetahui hubungan antara kecanduan game online dengan perilaku agresif pada remaja di Mabar Hilir kota Medan. Agresi adalah perilaku menyakiti seseorang, baik secara fisik maupun psikologis. Salah satu faktor perilaku agresif adalah kecanduan game online. Kecanduan game online adalah ketidakmampuan mengontrol perilaku bermain game online yang menyebabkan masalah sosial dan masalah emosional bagi pelaku. Sampel dalam penelitian ini sebanyak 70 orang dengan menggunakan teknik sampling kuota berdasarkan kriteria: remaja yang bermain game online pertarungan, bermain selama minimal satu tahun, bermain game online minimal 3 jam perhari atau 20-25 jam seminggu. Pengambilan data menggunakan skala kecanduan game online dan perilaku agresif yang diuji menggunakan product moment. Berdasarkan hasil analisis diketahui bahwa Ada hubungan positif kecanduan game online dengan perilaku agresif, dimana rxy = 0,600 dengan signifikan p = 0,000 < 0,05. Artinya hipotesis ada hubungan positif kecanduan game online dengan perilaku agresif. Dengan asumsi semakin tinggi kecanduan game online maka perilaku agresif semakin tinggi, dan sebaliknya. Hipotesis diterima. Koefisien determinan (r2) dari hubungan antara variabel X dengan variabel Y sebesar r2 = 0,360, ini menunjukkan bahwa kecanduan game online berkontribusi terhadap perilaku agresif sebesar 36%. Masih terdapat 64% faktor lain yang mempengaruhi perilaku agresif. This study used quantitative correlational aimed to find out the relationship between online gaming addiction and aggressive behavior in adolescents in the lower reaches of medan cities. Aggression is the behavior of hurting a person, both physically and psychologically. One of the factors of aggressive behavior is addiction to online games. Online gaming addiction is the inability to control the behavior of playing online games that causes social problems and emotional problems for the perpetrator. The sample in this study was 70 people using quota sampling techniques based on criteria: adolescents who played fighting online games, played for at least one year, played online games at least 3 hours per day or 20-25 hours a week. Data capture uses a scale of online gaming addiction and aggressive behavior tested using product moments. Based on the results of the analysis it is known that there is a positive association of online gaming addiction with aggressive behavior, where rxy = 0.600 with a significant p = 0.000 < 0.05. This means that the hypothesis is that there is a positive relationship of online gaming addiction with aggressive behavior. Assuming the higher the addiction to online gaming then the aggressive behavior is higher, and vice versa. Hypothesis accepted. The determinant coefficient (r2) of the relationship between variable X and variable Y of r2 = 0.360, this indicates that online gaming addiction contributes to aggressive behavior by 36%. There are still 64% of other factors that influence aggressive behavior
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

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
