Abstract
Purpose
The purpose of this paper is to study the transformation of some macropollutants including hydrocarbons, surfactants and metals in Milan west sewer basin. The study is part of a wider research (named SWARMNET and proposed by Politecnico di Milano and Metropolitana Milanese S.p.A and has been classified as fundable by the Ministry of Education, University and Research of Italy), aiming at installing a monitoring system for measurement of accidental discharge of pollutants from industrial activities and real-time protection of the wastewater treatment plant (WWTP) by avoiding dangerous discharges entering the sewers. Good effluent and waste sludge quality allow safe agricultural reuse of both streams. Other objectives include food safety, lower treatment costs and reduction of pollution of soil, surface and groundwater.
Design/methodology/approach
The west basin of Milan sewer network, discharging to San Rocco WWTP was considered. Among 700 industries, 16 have been selected for their specific characteristics and/or high industrial pollution load. A quality model was coupled with a hydraulic model to evaluate the effect of pollutants transport in the network.
Findings
Heavy metals, surfactants and hydrocarbons have different behavior from biodegradable domestic sewage and can be modeled as conservative matter conveyed by advection only. Results show that the concentration values of these macropollutants at the inlet of the WWTP are below the Italian standard values with the exception of Cadmium and Mercury. These heavy metals should be considered in the planned sampling campaign.
Originality/value
This study will estimate environmental benefits and both methodology and monitoring techniques can be extended to other cities in Italy and Europe.

Abstract
Purpose
The purpose of this paper is to analyze the emergence and development of public relations in Italy between 1945 and 1960. Its aim is to examine the main actors (corporate and political) involved in the process, how they were influenced by the USA and the emergence of professional associations devoted to expanding the field
Design/methodology/approach
The paper is based on research conducted in US and Italian archives and libraries. It analyzes primary sources concerning corporations, government agencies and professional associations involved in promoting public relations in post‐war Italy, such as the United States Information Service, Standard Oil (NJ), Fiat, Piaggio, Olivetti, Pirelli, Intersind.
Findings
This paper argues that the introduction of public relations in postwar Italy was strongly influenced by US companies and government agencies, which had a considerable impact on the emergence of professional associations. It also looks at the specific Italian definitions of public relations and points out that in Italy the field of public relations emphasized the importance of “style” and culture over that of marketing, and was often carried out by an array of “humanists” (poets, graphic designers, and writers).
Originality/value
This paper is one of the first studies about the history of public relations in Italy. It points out the peculiarity of the Italian case, by showing the intersection between the terms “propaganda” and “public relations” in a country that had experienced 20 years of Fascist rule.

Abstract
Purpose
This paper aims to focus on the design of algorithms and techniques for an effective set expansion. A tool that finds and extracts candidate sets of tuples from the World Wide Web was designed and implemented. For instance, when a given user provides <Indonesia, Jakarta, Indonesian Rupiah>, <China, Beijing, Yuan Renminbi>, <Canada, Ottawa, Canadian Dollar> as seeds, our system returns tuples composed of countries with their corresponding capital cities and currency names constructed from content extracted from Web pages retrieved.
Design/methodology/approach
The seeds are used to query a search engine and to retrieve relevant Web pages. The seeds are also used to infer wrappers from the retrieved pages. The wrappers, in turn, are used to extract candidates. The Web pages, wrappers, seeds and candidates, as well as their relationships, are vertices and edges of a heterogeneous graph. Several options for ranking candidates from PageRank to truth finding algorithms were evaluated and compared. Remarkably, all vertices are ranked, thus providing an integrated approach to not only answer direct set expansion questions but also find the most relevant pages to expand a given set of seeds.
Findings
The experimental results show that leveraging the truth finding algorithm can indeed improve the level of confidence in the extracted candidates and the sources.
Originality/value
Current approaches on set expansion mostly support sets of atomic data expansion. This idea can be extended to the sets of tuples and extract relation instances from the Web given a handful set of tuple seeds. A truth finding algorithm is also incorporated into the approach and it is shown that it can improve the confidence level in the ranking of both candidates and sources in set of tuples expansion.

Abstract
Purpose
The purpose of this research is to provide a systematic insight into corporate social responsibility (CSR) and corporate citizenship (CC) in supply chain development, by analyzing the current literature, contemporary concepts, data and gaps for future discipline research.
Design/methodology/approach
This research identifies information from existing academic journals and investigates research designs and methods, data analysis techniques, industry involvement and geographic locations. Information regarding university affiliation, publishers, authors, year of publication is also documented. A collection of online databases from 2001 to 2018 were explored, using the keywords “corporate social responsibility”, “corporate citizenship” and “supply chain” in their title and abstract, to deliver an inclusive listing of journal articles in this discipline area. Based on this approach, a total of 164 articles were found, and information on a chain of variables was collected.
Findings
There has been visible growth in published articles over the last 18 years regarding supply chain sustainability, CSR and CC. Analysis of the data collected shows that only five literature reviews have been published in this area. Further, key findings include 41% of publications were narrowly focused on four sectors of industry, leaving gaps in the research. 85% centered on the survey and conceptual model, leaving an additional gap for future research. Finally, developing and developed nation status should be delineated, researched and analyzed based on further segmentation of the industry by region.
Research limitations/implications
This research is limited to reviewing only academic and professional articles available from Emerald, Elsevier, Wiley, Sage, Taylor and Francis, Springer, Scopus, JSTOR and EBSCO containing the words “corporate social responsibility”, “corporate citizenship” and “supply chain” in the title and abstract.
Originality/value
This assessment provides an enhanced appreciation of the current practices of current research and offers further directions within the CSR and CC in supply chain sustainable development.
