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
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
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
CALORIES CALCULATOR AND ANDROID SUGGESTER APP
Get PDFcalorie calculator is a tool used to estimate the number of calories a person needs based on factors such as their age, gender, height, weight, level of physical activity, and health or fitness goals. Calorie calculators are often used in weight loss programs, food management, or daily caloric intake exercises.
While calorie calculations can provide a rough estimate of a person's caloric needs, it is important to remember that these are estimates only and the figures provided may not be accurate for every individual. There are some individual factors that the calorie calculator cannot take into account, such as individual metabolism, body composition, and genetic factors.
In addition, calorie calories also do not take into account other nutritional factors such as the type of food consumed, nutritional quality, and individual needs for certain macronutrients and micronutrients. Therefore, it is important to consider food quality and balanced nutrition when planning a healthy diet and eating pattern.
It is also important to remember that successful weight loss or food management does not only depend on calorie counting, but also involves factors such as program adherence, physical activity, good sleep patterns, stress management, and social support.
In terms of caloric use, it is advisable to take the results as a preliminary guide and talk to a health professional, such as a nutritionist or doctor, for more accurate and specific recommendations according to your needs and health conditio
Pengaruh budaya organisasi dan employee enggagement terhadap kinerja karyawan pada pt wika bitumen
Get PDFIn the face of intense competition in the era of globalization as it is today, the company must maintain the assets it owns in order to be able to face the competition. One of the assets that did not escape the concern is the human resources within a company. PT Wijaya Karya Bitumen (WIKA Bitumen) is part of the company?s expansion specializing in asphalt industry on the island of Buton known as bitumen buton (asbuton). In business competition WIKA Bitumen considers each employee as human capital. This human capital concept applies the quality of employees can be improved through the provision of competence, knowledge, attributes, and abilities, which is manifested in the ability to work properly resulting economic value in development. Therefore, in the management of one of their assets, so as special treatment is needed to maintain loyalty and good performance to the company. Changes Organizational culture that occurred at PT. Wika Bitumen relates to Employee performance and success of the organization, by looking the employee engagement of PT. Wika Bitumen. By using the calculation of Structural Equation Modeling (SEM) through simple perposive sampling method, Organizational Culture and Employee Engangement have a significant positive effect, with value 17.58 from t-statistical test which means a significant positive effect, then organizational culture has a significant positive effect on performance of PT. Wika Bitumen, with a score of 2.18 of the statistical t-test, which means a significant positive effect. And Employee Engangement have a significant positive effect on the employee performance of PT. Wika Bitumen, that is 2.31 through statistical t-test which means a significant. Managerial implications to improve employee performance PT. Wika Bitumen is to re-develop the company's programs and policies, then evaluate the program regularly, the application of organizational culture can be carried out by provide the appropriate rights and obligations to the portion, then informed appropriately to employees by using a comprehensive system to be routinely monitored
