Integrating sustainability and resilience in the supply chain: A systematic literature review and a research agenda
Full text linkSustainability has emerged as an important industrial strategic outlook expanding beyond organizational boundaries to include the supply chain. Simultaneously, the industry has also been faced with supply chain resilience concerns. Research on the intersection of supply chain sustainability and resilience is nascent and is a consequence of their observed mutual influences. However, confusion about concepts, implementation methods, and measurements of sustainable and resilient supply chains remains. This study completes a systematic literature review that critically examines several major observations and directions. We find the concept of sustainable supply chains is more established, and general agreement on its theoretical foundations exists. Supply chain resilience is relatively less mature. The nexus and relationships between the two topics are often incoherent: there is confusion on sustainable and resilient supply chains establishment; there is no clarity on what practices could jointly advance both areas. A major conflict exists since sustainability generally focuses on efficiency, while resilience seeks effectiveness. We recommend studies to analyze implementation relationships and impact. We also observe that performance measurement systems should be developed to assess supply chain sustainability and resilience performance taking with explicit consideration time horizons considered in these measures

No full textIndustry 4.0 and sustainability: Towards conceptualization and theory
Full text linkBoth Industry 4.0 and sustainability have gained momentum in the academic, managerial and policy debate. Despite the relevance of the topics, the relation between Industry 4.0 and sustainability – revealed by many authors – is still unclear; literature is fragmented. This paper seeks to overcome this limit by developing a systematic literature review of 117 peer-reviewed journal articles. After descriptive and content analyses, the work presents a conceptualization and theoretical framework. The paper contributes to both theory and practice by advancing current understanding of Industry 4.0 and sustainability, especially the impact of Industry 4.0 technologies on sustainability practices and performance
Signal and Backward Raman Pump Power Optimization in Multi-Band Systems Using Reliable and Fast Power Profile Estimation
Full text linkThis paper presents an efficient numerical method for calculating spatial power profiles of both signal and pump with significant Interchannel Stimulated Raman Scattering and backward Raman amplification in multiband systems. This method was tested in the optimization of a C+L+S/C+L+S+E 1000 km link, employing three backward Raman pumps, by means of a closed-form EGN model (CFM6). The results show a 100x computational speed increase, enabling deep optimization which made it possible to obtain very good overall system performance and flat GSNR
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
Emergy Analysis of an Industrial Park: The Case of Dalian, China
No full textWith the rapid development of eco-industrial park projects in China, evaluating their overall eco-efficiency is
becoming an important need and a big challenge academically. Developing ecologically conscious industrial
park management requires analysis of both industrial and ecological systems. Traditional evaluation
methods based on neoclassical economics and embodied energy and exergy analyses have certain limitations
due to their focus with environmental issues considered secondary to the maximization of economic and
technical objectives. Such methods focus primarily on the environmental impact of emissions and their
economic consequences. These approaches ignore the contribution of ecological products and services as
well as the load placed on environmental systems and related problems of carrying capacity of economic and
industrial development. This paper presents a new method, based upon emergy analysis and synthesis. Such
a method links economic and ecological systems together, highlighting the internal relations among the
different subsystems and components. The emergy-based method provides insight into the environmental
performance and sustainability of an industrial park. This paper depicts the methodology of emergy analysis
at the industrial park level and provides a series of emergy-based indices. A case study is investigated and
discussed in order to show the emergy method's practical potential. Results from DEDZ (Dalian Economic
Development Zone) case show us the potential of emergy synthesis method at the industrial park level for
environmental policy making. Its advantages and limitations are also discussed with avenues for future
research identified
