Agile supply chain management: where did it come from and where will it go in the era of digital transformation?
No full textIn today's dynamic business environment, agile supply chain (ASC) has become a key strategic move to cope with market instability, handle competitive pressures and strengthen operational and organizational performance. Meanwhile ASC is a good example of a strategy drawing heavily on digitization since as a demand chain management it was information-centric and technology-centric from its inception. Yet, despite this relationship, a lack of coherence and clarity around the input of technology for ASC has impeded to portray accurately the relative importance of digitization in ASC strategies. This study provides a comprehensive and integrative review of 90 articles on ASC. By so doing, we contribute to the discussion about digitization in the supply chain in several ways. First, the paper reports descriptively and analytically how technology was addressed within the ASC literature. Second, it maps a nomological network of ASC research. Third, it finds that technology appears as a necessary but not-sufficient enabling factor for ASC deployment. Finally, a research agenda is proposed to suggest future research avenues to improve contributions to ASC performance
Shaping the Future of Cold Chain 4.0 Through the Lenses of Digital Transition and Sustainability
No full textThe digitization of supply chain management lies at the crux of modern industry and similar trends are noticeable in the cold chain (CC) under the cold chain 4.0 (CC 4.0) concept. However, the extant research lacks a systematic summary of existing findings on CC 4.0. Therefore, this article provides a bibliometric and network analysis of 618 high-quality CC 4.0 publications extracted from the Web of Science. The article uses performance assessment and science mapping to investigate the impact of digital and sustainable technologies in the CC domain. Four main research streams and 19 research propositions are identified to provide an informative overview of the most recent developments in the emerging and growing domain of CC 4.0 and the interface between information systems and operations management. The article further identifies the critical role and impacts of digital-sustainable transformation and presents an agenda for future research focusing on critical theoretical and managerial areas that remain understudied
Managing supply chain resilience to pursue business and environmental strategies
No full textResilience has become a crucial topic in the field of strategic management as it requires companies to design resilient business models to tackle managerial and environmental disruptions of individual firms and supply chains. However, extant research still lacks deep insights into how companies design and manage supply chains according to the resilience principles. With this premise, this paper aims at conducting a state of the art review on supply chain resilience (SCR) considering 125 relevant papers collected from Scopus and Web of Science academic search engine. Starting from the results of the literature review, this study proposes a systemic framework of SCR assessment and contributes to improve the understanding of the impact of different empirically tested constructs on the development of the resilience concept. Further, the findings are summarized in several areas including barriers in developing resilience, metrics to measure the resilience performance, and effective strategies to foster the SCR. Finally, this study outlines promising future research directions for scholars and practitioners
What we learn is what we earn from sustainable and circular construction
No full textSustainable and circular construction entails emissions and wastes reduction through the reuse and recycling of materials to achieve economic gains and save resources for future generations. This work aims to map the academic research on sustainable and circular construction from different imperative angles on the Web of Science (WoS) database. In this line, we classified and reviewed the existing research using a bibliometric and network analysis approach into the following themes: life cycle assessment (LCA), green assessment tools, technologies and methods, quantification of recycling of waste and energy, building information modeling (BIM), greenhouse gas emissions in construction, and greenhouse gas emissions in the specific case of novel construction types. The study provides a bird-eye-view of existing qualitative and quantitative research findings within the themes above. Subsequently, the study highlights the future research avenues within each theme to develop the domain further. The work will assist practitioners and policy-makers in understanding the current status of sustainable and circular construction and suggest necessary actions to attain environmental sustainability
Moving toward sustainability and circularity in hill road construction: a study of barriers, practices and performance
No full textPurpose: This study explores the relationships among sustainability implementation barriers (resource, managerial and regulatory barriers), sustainability practices (sustainable construction materials, sustainable construction design, modern construction methods and environmental provisions and reporting) and sustainability performance (environmental, economic and social) in hill road construction (HRC). Design/methodology/approach: Primary data were collected from the 313 HRC practitioners with the help of a questionnaire, and research hypotheses were tested employing structural equation modeling. Findings: The findings reveal a mixed effect of sustainability implementation barriers. Resource (managerial) barriers are negatively related to all practices except environmental provisions and reporting (sustainable construction materials), while regulatory barriers only negatively impact modern construction methods. On the other hand, all sustainability practices positively impact environmental performance, whereas economic (social) performance is positively influenced by all practices, except environmental provisions and reporting (modern construction methods), and positively affects economic performance. Originality/value: In order to transform HRC toward sustainability, the barriers to sustainability implementation, sustainability practices and performance need to be understood by practitioners; however, the relationships have not previously been empirically assessed in extant literature. Besides, past research appears to be predominantly focused on the environmental aspect, thereby neglecting economic and social aspects. This study is a modest attempt to bridge these research gaps
Food cold chain management: What we know and what we deserve
No full textPurpose: The purpose of this paper is to present a quantitatively supported explanation of the intellectual
development, the schools of thought and the sub-areas of food cold chain (FCC) research to derive
meaningful avenues for future research.
Methodology: This study builds on bibliometric analysis and network analysis to systematically evaluate
a sample of 1,189 FCC articles published over the last 25 years. The descriptive statistics and science
mapping approaches using co-citation analysis were performed with VOSviewer software.
Findings: The findings reveal a state-of-the-art overview of the top contributing and influential
countries, authors, institutions, and articles in the area of FCC research. A co-citation analysis, coupled
with content analysis of most co-cited articles, uncovered four underlying research streams including: 1)
application of RFID technologies; 2) production and operation planning models; 3) postharvest waste,
causes of postharvest wastage and perishable inventory ordering polices and models; and 4) critical issues
in FCC. Current research streams, clusters and their sub-themes provided meaningful discussions and
insights into key areas for future research in FCC.
Originality: This study might reshape practitioners’, researchers’, and policy-makers’ views on the
multifaceted areas and themes in the FCC research field, to harness the benefits from FCC both at a
tactical and at a strategic level. Finally, the research findings offer a roadmap for additional research to
yield more practical and modeling insights that are much needed to enrich the field
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
