Government eco-innovation incentives in a recycling system: A Stackelberg-type model
No full textAs past economic progress has come at the expense of diminishing natural resources, increasing pollution and widespread damage to ecosystems around the world, an imperative we must respond to is to seek ways in which to achieve economic, social, and environmental sustainability, including actions aimed at a circular economy and eco-innovation. Recycling has numerous implications for the environment, economic and production performance, employment, and production of wealth. The environmental regulator must therefore consider all the aspects of the waste cycle when deciding the right policies to maximize social welfare. We consider three types of agents involved in a Stackelberg game: manufacturers, importers and sellers (MIS), recyclers, and the government acting as an Environmental Protection Agency (EPA). In our model, we introduce the cost to adopt new technology for eco-innovation per unit produced by the MIS, resulting in the possibility to reduce the weight of the advanced recycling fees if they invest more in the aptitude to be recycled of their products. The results give interesting prompts to investigate the relationship between environmental taxation and ecological incentives
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
Accessibility analysis in spatial planning: A case of special economic zones (SEZs) in Campania, Southern Italy
Full text linkThe strategic role of Special Economic Zones (SEZ) at the Italian level has also been underlined by the Italian National Recovery and Resilience Plan, which has provided an important economic endowment to relaunch the national economy, in general, and the Campania region territorial economy, in particular. Literature and best practices clearly show that many factors determine the success of a SEZ, with transport accessibility being one of the key factors. This study performs a transport accessibility analysis both at national and first/last-leg levels, by comparing the accessibility of the Campania SEZ areas, the other SEZ areas in Italy and all the other Italian local labour systems. The study focuses on the Campania region, as it represents the first Italian pilot project of spatial planning through the establishment of SEZs. The Campania region exhibits, on average, good transport accessibility both at a national level (considering the multi-modal freight Italian transport network) and at a first/last-leg level (considering relevant nodes of the network, such as tollbooths, freight stations, ports, interports and airports). Also, the impact of SEZ implementation on land use planning has been discussed, to provide a useful tool for stakeholders that are interested in revitalizing the area, at different levels: i) land use policymakers, to plan interventions/planning concerning infrastructures and spatial planning; ii) national policymakers, to establish SEZs in other geographical areas; iii) investors, to assess the convenience of investments in this geographical area
The role of logistics in promoting Italian agribusiness: The Belt and Road Initiative case study
No full textThe increasing policy interest in the Belt and Road Initiative (BRI) has stimulated an interesting debate in the research community. Although there are numerous studies focusing on this issue, in literature little attention has been devoted to the impact of the initiative on the performances of Italian firms involved in agribusiness. In order to bridge this gap, this paper focuses on wine as a high-quality commodity exported all over the world and considered an epitome of Made in Italy. Furthermore, ports of Venice and Trieste was selected for the analyses as being part of BRI agreements. This study highlights that the BRI project may modify land use planning as a consequence of the policymakers’ choosing a specific port to serve as the Italian connection to the BRI. The heterogeneity that might influence regional data needs the usage of specific approaches (the order-α and order-m) to evaluate the firms’ efficiency as a consequence of two different links to the ports of Trieste and Venice. The authors attempt to perform this investigation considering the predicted effects of the BRI, and several different databases are used to examine these potential effects. The evaluation of accessibility in terms of distance and transport time could provide helpful details to policymakers when looking at different BRI alternatives. To achieve the analysis, the authors also consider dimensions connected to specific financial statements and labour, environmental and business innovation indicators. The results reveal that, when the scenario involves a specific port, some differences appear in the ranking of firms. The findings also show that the spatial effect connected to the choice of a specific port decreases for small firms. Since the Italian agribusiness sector – specifically the wine sector – is characterized by a prevalence of small and/or family firms, it is recommended that policymakers deal with the conclusions of present research to compare different BRI options from a land use point of view
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
