Editorial - "RFID for fashion: Advancements in research, technology and implementation" for International Journal of RF Technologies: research and applications
No full textThe fashion industry is an increasingly complex and dynamic field, characterised by the advent of own brands and the globalization of sourcing and supply chain decisions. This context has recently attracted the attention of several researchers in the area of operations and supply chain management. Accordingly, the main criticalities of the fashion industry include short product life cycle, high volatility, and low predictability of demand and high purchasing impulse. Moreover, as in any other manufacturing business, balancing production and demand is a further challenge faced by fashion retailers, exacerbated by the fact that demand is highly variable and influenced by trends, the short selling season, as well as the need to produce and provide various, complex and fashionable textile products.
Radio frequency identification (RFID) technology offers attractiveways to improve supply chain efficiency through greater coordination between marketing and manufacturing. RFID enables real-time tracking of items, safety monitoring and automation of warehouse operations, which leads to increase in sales volumes and improved profitability for suppliers and retailers. Moreover, RFID implementation in a business organization has a significant impact on the entire supply chain efficiency, from suppliers to retailers. RFID also has the potential to help retailers solve several key issues of the fashion industry. Because of the short product life cycle of fashion items, it is
vital to ensure that the product is delivered to the store as quickly as possible. Since RFID provides the capability to track and trace items, it could streamline many activities along the supply chain. Fashion retailers often need space to display products of different styles, sizes and colours; consequently, efficiently managing items at retail stores becomes a relevant task. An RFID-based stock management system can help employees identify the needed items for the customer more quickly and accurately, at the same time enabling frequent inventory counts of high value merchandise. Moreover, RFID gives each clothing item a special identifier, so that counterfeiting and the practice of selling products illegally can be prevented or at least reduced. Finally, RFID is a promising technology for EAS in the apparel industry, where thefts are one of the main causes of shrinkage. On the basis of the premise above, our aim with this special issue is to provide state of-the-art findings about the use of RFID in the fashion field, in terms, for instance, of the design of new RFID solutions for fashion or technological developments in that field, of business models for RFID in fashion, and of RFID implementations in that industry. This special issue consists of 4 papers, with different topics addressed. In the first paper, Hinkka et al. propose a typology of RFID-based tracking solutions designed to fit differing supply chains. The typology developed is based on a case study, involving a logistics service provider interested in designing a tracking solution for different customers in fashion logistics, and four fashion retailers. The proposed typology enables fashion companies to consider which configuration of RFID tracking best fits the requirements and constraints imposed by their supply
chain. Moreover, the typology is expected to enable incremental implementation of supply chain-wide tracking. The second paper, by Bevilacqua et al., proposes the implementation of the RFID technology in an Italian company leader in the furniture industry and involved in the fashion field. The analysis grounds on the business process reengineering approach and highlights the benefits of implementing the RFID technology across the company’s various business processes. A cost analysis of the reengineered scenarios is also proposed. Rinaldi and Bandinelli, in the third paper, present a practical tool to support practitioners, consultants and researchers in achieving improvements in the effectiveness of logistics processes in the fashion supply chain, by determining the expected profitability of the RFID technology investments. The aim of their approach is to support practitioners and managers in evaluating a priori the profitability of an RFID investment in the fashion supply chain, estimating the related pay-back period; indirectly, this approach is also expected to increase the success of RFID-based project implementations while reducing the uncertainty in terms of economical results. In the fourth paper, Piramuthu et al. develop a protocol to test the performances of RFID devices adopted in the fashion field. The protocol matches the operational conditions of many supply chain processes, but is expressively tailored to the apparel industry. The authors use the protocol to assess the performance of different RFID devices (e.g., inlays, fixed and handheld RFID readers and printers), thus providing a benchmark for their deployment in the apparel logistics. Thanks to the variety of topics addressed, we believe that this special issue provides the scientific community with valuable information and knowledge related to RFID deployment in the fashion industry. Obviously, the value-added of a special issue is only as good as the contributions of the manuscripts received, and the quality of the
feedback provided by the reviewers. Therefore, we are very grateful to all the authors, who supported this special issue through their contributions, and to the reviewers, who helped us in managing the papers received in a timely manner and provided useful and professional reports about their quality. Finally, we would like to express our gratitude to the Editor-in-Chief of International Journal of RF Technologies: Research and Applications, which gave us the possibility of organizing the special issue and helped us in its successful completion
Dynamics of Network Formation Processes in the Co-Author Model
Full text linkThis article studies the dynamics in the formation processes of a mutual consent network in game theory setting: the Co-Author Model. In this article, a limited observation is applied and analytical results are derived. Then, 2 parameters are varied: the number of individuals in the network and the initial probability of the links in the network in its initial state. A simulation result shows a finding that is consistent with an analytical result for a state of equilibrium while it also shows different possible equilibria.Dynamics, Network, Game Theory, Model,Simulation, Equilibrium, Complexity
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
An MDP model for optimal handover decisions in mmWave cellular networks
No full textThe new frontier in cellular networks is harnessing the enormous spectrum available at millimeter wave (mmWave) frequencies above 28 GHz. The challenging radio propagation characteristics at these frequencies, and the use of highly directional beamforming, lead to intermittent links between the base station (BS) and the user equipment (UE). In this paper, we revisit the problem of cell selection to maintain an acceptable level of service, despite the underlying intermittent link connectivity typical of mmWave links. We propose a Markov Decision Process (MDP) framework to study the properties and performance of our proposed cell selection strategy, which jointly considers several factors such as dynamic channel load and link quality. We use the Value Iteration Algorithm (VIA) to solve the MDP, and obtain the optimal set of associations. We address the multi user problem through a distributed iterative approach, in which each UE characterizes the evolution of the system based on stationary channel distribution and cell selection statistics of other UEs. Through simulation results, we show that our proposed technique makes judicious handoff choices, thereby providing a significant improvement in the overall network capacity. Further, our technique reduces the total number of handoffs, thus lowering the signaling overhead, while providing a higher quality of service to the UEs
