Factors disrupting supply chain management in manufacturing industries
Get PDFThis paper aims to explore the causes of supply chain management disruptions in the manufacturing sector. Supply chain disruptions have become a major concern for companies globally, posing significant risks to business operations, costs, earnings, and customer satisfaction. This review examines various factors contributing to these disruptions, including natural disasters, raw material unavailability, regulatory changes, technology breakdowns, labor shortages, transportation issues, and political instability. The review encompasses studies and research papers shedding light on the causes of disruptions in manufacturing supply chains. The findings highlight the importance of proactive measures in building resilient supply chains capable of effectively handling disruptions. These measures involve implementing robust risk management plans, strategic investments in technology, and developing collaborative relationships with customers and suppliers. Through these actions, manufacturing companies can enhance their supply chain\u27s ability to withstand disruptions and ensure uninterrupted operations. In conclusion, this review emphasizes the critical importance of addressing supply chain disruptions in the manufacturing sector and advocates for a proactive and comprehensive approach to mitigating their impact. Effective risk management strategies, technology investments, and strong partnerships are key to enhancing the resilience of supply chains and minimizing the negative consequences of disruptions
Medical tourism supply chain under scrutiny: a hybrid grounded theory and DEMATEL method
Get PDFThis study sought to provide a comprehensive analysis of the medical tourism supply chain (MTSC) in Shiraz, Iran, to improve the city’s potential tourism market share in the post-COVID-19 future. The study relied on a mixed research methodology. Primarily, semi-structured interviews were conducted with 12 stakeholders involved in Shiraz MTSC. The data from the interviews were then analyzed using grounded theory (GT). To detect any interrelationships among the elements, the model was further analyzed quantitatively through the rough DEMATEL (decision-making trial and evaluation laboratory) method. Rough set theory was used to aggregate group information to overcome the vagueness of the group decision-making process. The results of the qualitative phase helped to configure a model which included 6 main dimensions, 17 sub-dimensions, and 48 elements. Also, according to the quantitative findings, “poor service delivery” was the most significant threat and challenge facing medical tourism in the studied city. The study provides practical insights that could help to improve the states of different stakeholders in the MTSC of developing countries
Decarbonization through modal shift using a synchromodal platform: A case study in the Great Lakes
Get PDFThis paper offers an empirical study to explore the relationship between transportation modalities and environmental concerns, promoting the adoption of synchromodality as a strategic pathway to achieving sustainable freight transport. The study uses a synchromodal freight transportation platform to analyze the impact of carbon tax policy on modal shift and environmental sustainability. The synchromodal platform is based on an optimization model using Mixed Integer Linear Programming (MILP), incorporating carbon tax as a surrogate measure for environmental costs. A sensitivity analysis is conducted across four distinct scenarios in a case study in the Great Lakes region, focusing on the Canada-US transborder trade. The results of this study illustrate the considerable potential for increasing the utilization of more environmentally sustainable transportation modes in this region. While the addition of carbon tax entails increased total transportation costs for each unit of cargo, the synchromodal-enabled modal shift promises to mitigate transportation’s negative externalities, including congestion, environmental impacts, and noise pollution. The results also highlight the role of synchromodality as a catalyst for sustainable freight transport decisions in the context of a carbon-conscious world
Project Diary as a Strategy of Urban Apprehension: The Case Study of Thessaloniki
Get PDFThis article is part of the strategy of understanding the urban fabric of Thessaloniki through a project diary composed of sketches, photographs, and local research of the urban evolution of the city. It was produced along a whole month with the objective of supporting urban planning proposals for the S.O.S. – Sustainable Open Solutions for European urban waterfronts programme, in January/February of 2022. The working method (in action investigation) produced important results de-rationalizing the planning process and stimulating new ways of thinking about contemporary urban problems. In a time when authors talk about the death of humanism, because there are no more ties that can keep society united, the article propose here an exercise in which progressive and rational thinking for urban planning methodologies are not the protagonist
Skopje: Skopje Brutalism Trail: Rebuilding Social Fabric through Architecture and Performance
No full textThe article reflects the city of Skopje from the perspective of the workshop Skopje Brutalist Trail held in late September 2022 as a part of the activities focused on fieldwork within the COST Action Writing Urban Places. The workshop departs from the general topics of brutalist architecture and solidarity, both highly relevant and related to the city and its culture. The idea of the workshop is to offer a new viewpoint by means of civic participation and activism in order to reassess forms of solidarity in the process of community building. The workshop engages creative writing and performing arts to develop urban narratives that link architectural legacy, in-situ findings and memories of people and places, juxtaposing past, present and future narratives. 
Almada: The Other Margin
Get PDFAlmada, which is both a city and a county located on the south bank of the Tagus River and part of the Lisbon metropolitan area, has a unique identity that is influenced by both its proximity to and separation from Lisbon. This so-called ‘other margin’ was built on the productive base of the agricultural and fishing industries, the military and quarantine infrastructure, the burgeoning tourist industry on the Atlantic waterfront, the significant naval shipyard presence on the riverfront, the communal associations and cooperatives in the towns, and the expanding suburban condition throughout the entire territory. Almada is depicted here from various angles using various ways of representing its people, places, events and narratives that were taken from literary, artistic, architectural and documentary sources like books, illustrations, models, photos and movies. The urban narratives of Almada are replayed, alternating back and forth between past and present, memories and reality, the written and the visual. 
Exponentially Reduced Reflection (ERR) versus Linear Wave Theory (Airy-Laplace)
Get PDFThe linear wave theory according to Airy/Laplace (1842) is widely used by engineers however violates the law of conservation of mass and considers local ground inclination α = 0⁰ only.Both shortcomings can be avoided(a) by extending Schulejkin\u27s mirror method to represent orbital kinematics over flat ground to inclinations 0⁰ ≤ α ≤ 90⁰ and(b) by referring to the phase shift Δϕ between incident and reflected waves according to the author´s definition of the complex reflection coefficient CRC.This contribution includes Exponentially Reduced Reflection (ERR) for the first time as a wave theory applicable to complex boundary conditions, considering a priori an important cause of wave deformation over inclined seafloor.For instance, the change of the total orbital kinematics (orbital paths, velocities and accelerations) related to the water surface is shown for decreasing water depths on a slope 1 : n = 1 : 2.In contrast to the Airy/Laplace theory, lower orbital velocities are obtained above the still water level, which is important with respect to the design of offshore structures

eBird, Expertise, & the Technological Mediation Of Citizen Science
No full textTechnological advances in application development and open science continue to revolutionize and create new forms of citizen science. However, as of today, the role of technology in citizen science has remained relatively unexplored. In this essay, we pose the question of how citizen science apps shape the practice of citizen science, looking specifically towards the popular birding app eBird as a case study. Through the citizen science practices co-shaped by eBird, this essay will dive into the functions of the application, how it can be regarded as shaping human-technology relations and the impacts this has on the relationship between citizen (scientist) and expert. After building the case for eBird’s influential role in citizen science with regard to birding, the discussion pivots towards the future of citizen science as a democratic process shaped by the technologies used to gather and share scientific data. This essay concludes by asking how a more democratic understanding of citizen science can be developed through both empowering citizens to not just participate in data gathering, but also to help interpret it in new and informed ways with the citizens’ own interests in mind. 
Sketching theory: Introducing the pictorial format
Get PDFThe Journal of Human-Technology Relations is committed to investigating human-technology relations from a wide range of academic disciplines and subdisciplines in the humanities and social sciences, from design to philosophy and everything in between. To provide a space for productive correspondence with these practices the journal offers authors the possibility to submit pictorials. Pictorials take seriously the mutually constitutive relation between material process and product. They are papers in which visual components (e.g. diagrams, sketches, illustrations, renderings, photographs, annotated photographs, gifs) play an important role. At a minimum, these visuals do more than support the text. At their best, they work together with the text in a way that makes meaning irreducible to either medium alone. In this pictorial we demonstrate this scope by example, making a philosophical argument with more than textual means
