Quality of students life and its role in strengthening the social responsibility with the students of Adrar University
No full textThe current study aims at determining the quality of student life in the University of Adrar and its role in strengthening the social responsibility. The study is based on the descriptive analytical method and applied on a sample composed of 90 students randomly chosen, however for the processing, the R program, pack SEMinR were applied.
On this basis, the results have showed that the level of quality of student life and social responsibility among the students of Adrar University was at a high degree, and there was a positive statistically significant relationship between the quality of family and social life, the quality of mental health, the quality of time management and social responsibility among university students, and the absence of a statistically significant relationship between the quality of public health, the quality of education and study, alongside the social responsibility of university students
Testing the effect of a day of the week in the Emirates Stock Exchange an econometric study: اختبار اثر يوم من الأسبوع في سوق الإمارات للأوراق المالية - دراسة قياسية
No full text يعد تأثير يوم من الاسبوع من أحد تشوهات التقويم الملاحظة في الأسواق المالية وهو من حالات شذوذ الصيغة الضعيفة لفرضية سوق فعالة، ومن الناحية التاريخية كانت العوائد السلبية لأول يوم تداول من الأسبوع هي النتيجة الأكثر شيوعا تماشيا مع تحسين كفاءة السوق وظهور المالية السلوكية. تهدف هذه الورقة إلى اختبار وجود أثر يوم من الاسبوع في سوق الامارات للأوراق المالية خلال الفترة الممتدة من 02/02/2020 إلى 30/06/2022، باستخدام الاحصاء الوصفي ونماذج ARCH، واعتمدت الدراسة على البيانات اليومية لكل من مؤشر FTFADGI ومؤشرDFMGI، وأظهرت النتائج وجود أثر يوم من الأسبوع في سوق الأمارات للأوراق المالية، مما يوفر دليلا على عدم كفاءة هذا السوق على المستوى الضعيف.Abstract: The effect of the day in the week is one of the calendar anomalies observed in the financial markets, and it is one of the irregularities of the weak formula of an efficient market hypothesis. Historically, the negative returns of the first trading day of the week have been the most common outcome in line with the improvement in market efficiency and the emergence of behavioral finance. This paper aims to test the impact of a day of the week in the Emirates stock market, during the period from 02/02/2020 to 30/06/2022, using descriptive statistics and ARCH models. The study was based on daily data from FTFADGI and DFMGI indexes. The results demonstrate the presence of an effect for a day of the week in the Emirates stock market, which provide evidence of the inefficiency of this market at the weak level
The Impact of Investor Sentiment on Stock Returns in the Indonesian Stock Market During the Period (2001-2022): An Econometric Study
No full textThe study aims to test the impact of financial investors\u27 sentiment on the returns of IDX Index (JKSE) stocks in the Indonesia Stock Exchange during the period from 2001-2022 using the autoregressive model conditional on the generalized inhomogeneity of variance (GARCH). The study was based on the monthly data of each of the consumer confidence index, which expresses investor sentiment, and the returns of the (JKSE) index.
The results showed that there was a statistically significant positive effect of the changes in investor sentiment on the returns of the (JKSE) index during the study period
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
