Model of Flexible Periodic Vehicle Routing Problem-Service Choice Considering Inventory Status
No full textVehicle routing problems and inventory problems need to be integrated in order to improve performance. This research discusses the determination of vehicle routes for product delivery with periodic delivery times that are released at any time depending on the inventory status. A mixed-integer linear programming model in determining periodic flexible visiting vehicles\u27 route considering inventory is proposed to solve this problem. This model also accommodates time window constraints, retailer warehouse capacity. The search for solutions was carried out using the branch-and-bound method with the help of Lingo 18.0. The mathematical model testing result saves shipping costs and inventory costs. In addition, the developing mathematical model offers the flexibility of visiting depending on the inventory status of the consumer. The sensitivity analysis of the model results in the vehicle capacity influence the total cost and routes formed
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
KEUNGGULAN MEKANISME KELAS KERJA SAMA PERGURUAN TINGGI DAN MITRAS DUDI (STUDI KASUS: POLITEKNIK NEGERI JAKARTA)
Full text linkUniversities are required to produce quality graduates according to the constant developments. To get quality graduates, universities must adjust the curriculum according to what is needed so that workforce absorption is in line with market demand. Collaboration mechanism becomes a way to collaborate with other parties to develop and increase the competitiveness of higher education, strengthen the image and quality of higher education. One way for Politeknik Negeri Jakarta (PNJ) to keep up with the change in of business and industry sector is to collaborate with industry, and in this case is with Mitras DUDI. The research used qualitative methods with a descriptive approach. This research aimed to present the phenomenon of the superiority of the cooperative class mechanism from the perspective of students, universities, and users (industry), as well as to see the absorption of cooperative class graduates by using data triangulation to ensure the quality and completeness of the data. Based on the results of data processing obtained from interview methods, participant observation, and document record analysis, an explanation regarding the phenomenon of the superiority of the cooperative class mechanism was obtained from the perspective of students, universities, and users (industry) through the cooperative class program. One of the advantages is that there is a greater opportunity for the cooperative class graduates to compete and work in the industrial and business sectors.Perguruan tinggi dituntut untuk menghasilkan lulusan yang berkualitas sesuai perkembangan zaman. Untuk mendapatkan lulusan yang berkualitas, perguruan tinggi harus menyesuaikan kurikulum sesuai dengan kebutuhan agar penyerapan tenaga kerja sesuai dengan market demand. Kerja sama merupakan cara untuk berkolaborasi dengan pihak lain untuk mengembangkan dan meningkatkan daya saing perguruan tinggi, menguatkan citra, dan mutu perguruan tinggi. Salah satu cara Politeknik Negeri Jakarta untuk mengikuti perkembangan dunia usaha dan industri adalah melakukan kolaborasi dengan industri, dan dalam konteks ini bersama dengan Mitras DUDI (Kemitraan dan Penyelarasan Dunia Usaha dan Dunia Industri). Penelitian menggunakan metode kualitatif dengan pendekatan deskriptif. Penelitian ini berusaha mengungkapkan fenomena keunggulan mekanisme kelas kerja sama dari sudut pandang mahasiswa, perguruan tinggi, dan pengguna (pihak industri), serta melihat keterserapan lulusan kelas kerja sama dengan menggunakan triangulasi data untuk menjamin kualitas dan kelengkapan data. Berdasarkan hasil pengolahan data yang didapatkan dari metode wawancara, participant observation, dan analisis dokumen (document record) didapatkan penjelasan terhadap fenomena keunggulan mekanisme kelas kerja sama dari sudut pandang mahasiswa, perguruan tinggi, dan pengguna (pihak industri) melalui program kelas kerja sama. Salah satu keunggulannya yaitu terdapat peluang yang lebih besar bagi lulusan kelas kerja sama untuk bersaing dan bekerja di dunia industri dan usaha
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
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
