An Approach to the Assessment of Resilience in Indonesian Fertiliser Industry Supply Networks
Full text linkThe fertiliser industry is a significant contributor to the Indonesian economy. Given the need to distribute its products to customers on the 17,000 islands making up the Indonesian archipelago, capacity and availability of ports is a major factor in managing fertiliser product lifecycles and the supply networks. Fluctuations in the availability of infrastructure influence levels of risk in the supply networks. Supply network resilience is important to maintain the performance of the Indonesian fertiliser industry. Currently, decision makers in the Indonesian fertiliser industry use risk assessment reports to assess resilience. Discussions with Indonesian fertiliser industry managers highlighted a second, port management, report that is used to evaluate the availability of infrastructure. An opportunity was identified to use both reports in assessing resilience.
This thesis is based on the premise that the risk assessment report can be used as an information resource for resilience assessment. A theoretical framework, based on a synthesis of literature and interviews with industry practitioners, is proposed. Results from interviews concluded that the supply network is a system consisting of social and technical factors. Thus, the approach needed to include both factors. Secondary data collected from risk assessment reports and primary data from brainstorming with key people in the industry were used to validate the approach. The theoretical framework was used to inform the construction of a conceptual model that was populated with data from a real-world case study. A simulation model was then built to translate the conceptual model into a practical application. The simulation model was used to investigate the results of the resilience assessment in different scenarios and predict levels of risk. Early feedback from Indonesian fertiliser industry practitioners indicated that the model could be valuable in the assessment of resilience.
This research provides a new approach for managers to predict the level of risk in supply networks. Since the Indonesian fertiliser industry is owned and governed by the Indonesian state, the approach could be used by policy makers as a prototype to assess the current condition of the supply network in Indonesian industries and the output could be used to underpin the planning of supply networks in the future. For academia, the approach provides a new theoretical framework for research on supply network resilience and presents a real example of how agent-based modelling might be used as a tool to support the assessment of resilience

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
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
MANAJEMEN RANTAI PASOK PADA INDUSTRI KECIL MENENGAH GARAM MADURA DENGAN PENDEKATAN HOUSE OF RISK
Full text linkMadura Island is recognized as a primary salt supplier in Indonesia, contributing significantly to national production. Despite this, its Small and Medium Enterprises (SMEs) face persistent challenges that create a precarious supply chain, characterized by noncompetitive pricing and extended, inefficient distribution networks. These vulnerabilities necessitate a structured approach to risk management. Therefore, this study aims to identify dominant supply chain risks, analyze their root causes, and formulate effective mitigation strategies for Madura salt SMEs. The methodology employs a two-stage approach. First, the Supply Chain Operation Reference (SCOR) model is used to map processes and identify potential risk events. Second, the House of Risk (HOR) model is applied. HOR Phase 1 prioritizes the risk agents based on their severity and occurrence, and HOR Phase 2 develops proactive mitigation actions. The research identified 9 distinct risk events and 23 corresponding risk agents across the SCOR processes. The HOR 1 analysis revealed that the most critical risk agents are insufficient solar heat intensity (A9), high precipitation (A10), price manipulation by intermediaries (A4), and inadequate salt processing competence (A11). From these priorities, seven strategic mitigation actions were formulated in HOR 2. The most crucial recommendations include implementing solar heat monitoring technology, developing contractual partnerships to stabilize prices, and providing technical training for farmers on salt processing standards. This research provides actionable strategies to enhance the overall resilience and sustainability of the salt SME supply chain.Madura, yang dikenal sebagai pulau garam, memberikan kontribusi sebesar 28% terhadap Indonesia. Namun, beberapa masalah terjadi dalam bisnis ini. Harga yang tidak kompetitif dan rantai distribusi yang panjang menciptakan proses rantai pasokan yang berisiko. Diperlukan identifikasi dan analisis risiko serta penyebab risiko tersebut. Selain itu, tindakan mitigasi diperlukan agar hambatan dan kerugian dapat diantisipasi.
