A Comparative Analysis of Hazard Analysis Methods for Sustainable Energy Development
No full textThis paper discusses the potential risks and dangers associated with the oil and gas industry. This industry is essential for meeting energy needs and generating foreign exchange income, but it also poses significant risks, such as accidents, fires, explosions, and environmental contamination. Neglected work and safety procedures can result in catastrophic economic losses and have far-reaching effects on society and the environment. The study describes three significant accidents in the industry that were caused by internal and external factors. In order to comprehend the causes of these incidents, this study suggests three risk analysis techniques: Failure Mode and Effect Analysis, Fault Tree Analysis, and Hazard and Operability Study. The paper asserts that by employing these methods, incident data can be obtained to enhance security and reduce the likelihood of future accidents. Overall, this study emphasizes the significance of safety measures, environmental management, and total quality management in the oil and gas industry in order to avoid fatal outcomes and environmental impacts
THE ANALYSIS OF WORK SHIFT PATTERNS AND RISK OF FATIGUE IN AIRCRAFT MAINTENANCE PERSONNEL: A CASE STUDY
Full text linkIn response to the COVID-19 pandemic in 2020, PT. XYZ, the biggest aircraft maintenance, repair, and overhaul (MRO) company in Indonesia, implemented a new shift pattern for line-maintenance personnel. The new shift pattern allows maintenance personnel to have fewer working hours per day (7-hour shifts) in more shift varieties for 5 consecutive days. Maintenance personnel will have 2-morning shifts, 1-noon shift, and 2-night shifts followed by 3 rest days. This study aims to explore the risk of fatigue caused by the newly implemented shift pattern. Data were collected through electronic questionnaires from a total of 303 respondents. This study found that at the time of the survey, many respondents (78 of 303, 26%) felt tired and had difficulty concentrating, regardless of the shift they were in. Based on the duty time, the highest scores of level 6 (tired, difficult to concentrate) were discovered on night shift day 5. This result shows that although the organization had provided the maintenance personnel with the opportunity to obtain sleep during rest days, tiredness and fatigue were still experienced by the aircraft maintenance personnel. This study recommends necessary actions to be taken to prevent fatigue, especially from the noon shift afterwards, where fatigue level is increasing, and alertness level is decreasing
Reducing Environmental and Health Risks in Construction Projects Through Hazard Identification and Risk Assessment
No full textThis study looks into the implementation of the HIRARC approach in five Indonesian construction companies in order to reduce risks to workers' health and the environment. Companies face increased pressure to maintain productivity as technology and manufacturing advance, which often results in a higher likelihood of worker injuries if they are not in compliance with OSHA regulations. To assess the effectiveness of the HIRARC technique, the study examines the companies' occupational health and safety, hazard identification, risk assessment, and risk control practices. Accidents continue to occur despite the companies' implementation of the approach, indicating the need for further development. As a result, the study recommends that OSHA management and construction workers receive HIRARC training and certification to reduce accidents and protect worker health and the environment. Implementing hazard identification and risk assessment methodologies can also assist construction firms in reducing environmental and public health risks, thereby promoting sustainable development. Overall, these findings emphasize the significance of implementing effective occupational health and safety practices in order to create a safer and healthier workplace
Minimizing Work Risks in Indonesia: A Case Study Analysis of Hazard Identification, Risk Assessment, and Risk Control Implementation
Full text linkWorkplace safety must be a primary priority in order to prevent work-related accidents that might result in disability or death. Promoting workplace safety is a crucial component of labor protection since it can lead to improved employee relations and management. Construction and industrial industries, which rely on heavy machinery or outside labor, are especially vulnerable to safety and health concerns that can lead to accidents. This case study and literature review investigates the Hazard Identification, Risk Assessment, and Risk Control (HIRARC) theory as a systematic method for promoting workplace safety. HIRARC seeks to identify potential hazards within an organization and control associated risks in order to prevent accidents. The study reveals numerous factors that contribute to occupational accidents and the potential harm they can inflict. The study specifically addresses worker attitudes toward the usage of personal protective equipment (PPE) and high-temperature production environments as accident risk factors. The study recommends that organizations prioritize instilling work discipline in their employees, with an emphasis on the correct use of PPE to prevent accidents and promote workplace safety
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
