Enhancing Efficiency in Railway Freight Logistics Using a Two-Stage Decision Support Technique with q-Rung Orthopair Fuzzy Sets
No full textEnhancing railway freight logistics efficiency is crucial for strengthening global supply chain performance, yet persistent challenges such as infrastructure limitations, operational inefficiencies, and fragmented intermodal integration hinder optimal performance. Despite its critical role in economic and environmental sustainability, limited research offers comprehensive, universally applicable solutions for addressing these issues. This study bridges this gap by introducing a novel multi-criteria decision-making (MCDM) framework that integrates inter-criteria correlation (CRITIC) and multi-objective optimization based on ratio analysis (MULTIMOORA) with Q-rung orthopair fuzzy sets (q-ROFSs) to handle complex and conflicting decision-making scenarios. These methods were selected for their complementary strengths. CRITIC effectively quantifies the importance of criteria by considering their interdependencies, MULTIMOORA offers robust multi-objective optimization capabilities, and q-ROFSs manage the inherent uncertainty and ambiguity of real-world logistics problems. Their integration provides a comprehensive framework capable of addressing both the complexity and uncertainty in railway freight logistics decision-making while offering actionable solutions to policymakers and industry leaders.The presentation of the authors' names and (or) special characters in the title of the pdf file of the accepted manuscript may differ slightly from what is displayed on the item page.

Modeling the effects of real time traffic information on travel behavior: A case study of Istanbul Technical University
No full textThis article adds to the literature on the investigation of choice behavior of travelers under the real-time traffic information acquired through some traffic applications such as GPS navigation devices for car, mobile traffic applications and radio traffic reports on traveler behavior on highways. Self-deviced survey of travelers was conducted for the civil engineering undergraduate – graduate students, academicians and supporting staff at Istanbul Technical University, Turkey in 2016. Multinomial logit mode choice model of the decision making for travel and commuter responses to traffic information were estimated separately in two different commute modes, including private cars and public transit. The attributes that influence travelers’ decision-making patterns were broadly categorized into three groups, which were socioeconomics, travel and technological characteristics. The analysis of the results indicated that travelers who obtained traffic information from some traffic applications were more likely to switch their route with respect to their different characteristics. Moreover, the travel pattern of the commuters regarding whether to change their choice of route or not varied with respect to their aforementioned characteristics as well as their selection of commute modes. The results of this research could also help to develop vehicular communication systems such as vehicle-to-infrastructure V2I communications
Evaluating the Influencing Factors on Adoption of Self-driving Vehicles by Using Interval-Valued Pythagorean Fuzzy AHP
No full textWill Conventional Public Transport Users Adopt Autonomous Public Transport? A Model Integrating UTAUT Model and Satisfaction–Loyalty Model
No full textAs an emerging technology for sustainable, safe, energy-efficient, and smooth traffic flow, autonomous public transport (APT) has been widely studied in recent years. However, the influence of conventional public transport (CPT) on behavioural intentions toward APT is largely overlooked. While APT is in its nascent phase, users’ choices may be shaped by their perceptions and attitudes toward CPT. Therefore, identifying these perceptions and examining their effect on behavioural intention is crucial. In this study, the Unified Theory of Acceptance and Use of Technology (UTAUT) is integrated with the satisfaction-loyalty model to analyze the key factors influencing behavioural intentions toward APT. To obtain more precise findings, this study examined public transport by type, including rubber-tired systems, urban rail, and bus rapid transit, rather than as a single mode, unlike many previous studies. A survey (n = 1271) was employed to validate the theoretical model among CPT users in Istanbul. The results indicate that loyalty to CPT significantly influences behavioural intention toward APT. Moreover, users of different CPT types have distinct priorities influencing their intention to use APT. While users of rubber-tired systems prioritize effort expectancy, social influence and facilitating conditions, users of urban rail systems consider social influence, trust and loyalty to CPT to be decisive factors. Furthermore, users of bus rapid transit systems consider performance expectancy, effort expectancy, trust, and loyalty to CPT as key factors influencing their behavioural intention. The findings are expected to enrich theoretical research on behavioural intention toward APT and guide future integration and transition between CPT and APT
The Anti-Social Web
No full textThis panel uses a range of sites and populations to investigate anti-social practices around and within the community spaces of the Web. We focus on how the cultural common sense of an open Web built on sharing is framed against the danger of specific anti-social practices and how practices of openness and sharing rely on anti-social acts for their maintenance. Thus the dominant imaginary of the web as both frictionless free market and anti-hierarchical public sphere has always been positioned against the trolls, bots, and freaks resisting this vision, while practices of censorship, surveillance, and social engineering have been adopted in defense of this vision.
These tensions between open sociality, its disruption, and its regulation have been present since the opening of the commercial web in the early- to mid-1990s. US politicians and telecommunications corporations in that period promised that ‘cyberspace’ would be cleared of pornography and theft in order to ensure that it was safe and open for business. The threat of marketing cyberporn to potentially susceptible publics would be met with legislation such as Children’s Internet Protection Act (CIPA), requiring all public access points receiving federal funding to install filtering software on their internet-connected PC’s (Jaeger & Zan, 2009). Simultaneously, MCI advertised cyberspace as an open zone of social and economic relations where bodily markers signifying past social divisions would disappear (e.g., the “Anthem” commercial advertising how online “there is no race”, “there is no gender”). This supported an emergent neoliberal political hegemony where any public insistence on the material effects of racism or sexism were themselves taken to be racist or sexist attacks on the ‘color-blind’ public sphere (Chun, 2006). These discourses circulating on and about the web are thus indicative of a new norm of sociality that takes old ideals of the open, democratic public sphere and repurposes them to support an economic infrastructure based on free flowing but data-mined information (Dean, 2003). Trolls, bots, spammers, porn freaks, and griefers use this open, free-flowing sociality transgressively to serve their own respective agendas and are thus a threat to the dominant political-economic order.
The rise of web 2.0 and social networking sites built on user-generated content re-centers the economic imperative of social openness and the political norms of social publicity. Here the profits of websites such as Facebook are always produced through uneven economic relations where users’ free labor becomes profitable data profiles through ubiquitous surveillance--the scope of which is hidden from most users (Anderjevic, 2012). Politically, we see reactions against the anti-social Web overlapping with offline liberal politics; including the way white, middle- and upper-class teenagers, many encouraged by parents, fled from MySpace to Facebook because the former encouraged media experimentation, heavily featured hip-hop culture, and, allegedly was overrun with sexual predators (boyd, 2012). In other words, mid-2000s MySpace was social, but not the right kind of social. The anti-social Web is thus both a set of infrastructural practices shaping a profitable, normative version of Web sociality, and a discourse against which those norms are constructed. The papers in the panel will argue that the anti-social web is not a bug in the system of the social web, but a constitutive feature of that system. To understand LambdaMOO, we must understand Mr. Bungle (Dibbell, 1998, p. 11-33). To understand ‘cyberspace’, we must understand cyberporn. To understand Facebook, we must understand the white flight from MySpace. And to understand Reddit, we must understand Violentacrez (Chen, 2012).
This panel explores how the anti-social web exists alongside the social web, as both a set of anti-social practices shaping a normative social space and a set of anti-social figures against which the liberal discourse of the web is defined. [Author’s 1] ethnography of urban public libraries explores how librarians regulate the links between internet access and social mobility, and how library patrons, many of them homeless, refuse those links when they watch porn, sleep, drink, or have sex in the library. [Author 2] explores how griefers' play has developed hacktivistic undertones and transformed into a strategy for negotiating privacy, transparency, and governance in virtual worlds. [Author 3] examines the phenomenon of ‘cloaked websites’ which hide their white supremacist or pro-life political agendas in order to influence naive Web users. And [Author 4] discusses the anti-democratic potential of ‘big data’ electoral campaigns, which use the data points generated in the putative public sphere of the web to engineer turnout rather than foster broader citizen engagement. With each of these papers, we see the anti-social web shaping the cultural common sense of the open, public social web--whether as a figure to be regulated in the name of norms of democratic publicity, or as a set of anti-democratic practices existing within those same norms.
