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.

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.

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.

This study will estimate environmental benefits and both methodology and monitoring techniques can be extended to other cities in Italy and Europe.

This paper aims to explore a theoretical relationship among perceptions of consumer social class, the perceived legitimacy of customer requests for service and the delivery of intangible services. It focuses the discussion on service firm encounters with non-traditional consumers seeking to purchase from luxury brands.

The paper reviews the literature for current trends in strategies of luxury brands and characteristics of evolving global and Asian consumer markets for luxury and neo-luxury goods and draws a theoretic model with propositions.

Evidence suggests that service providers can improve efforts to expand services to the newly rich and trading-up neo-luxury consumer markets by focusing on the intangible elements of the service delivery system. Particular emphasis is placed on enhancing employee treatment of neo-luxury customers during service encounters by understanding the influence of employee perceptions of consumer social class and evaluations of the perceived legitimacy of customer requests for service.

The paper contributes to the theoretical discussion in luxury brand management by suggesting that employees are influenced by impressions of customer worth and other attributes when determining responses to customers during service encounters. Implications for practitioners and future research directions for academics based on the framework are presented.

Disaster risk reduction is of prime importance in informal settlements in the Global South, where several forms of vulnerability coexist. Policy and official programmes, however, rarely respond to the needs and expectations of citizens and local leaders living in these settlements. Even though these agents constantly attempt to reduce risks in their own way, we know very little about their activities, motivations and effective impact on risk reduction. Here we seek to conceptualize bottom-up initiatives to better grasp their origins, limitations and success.

Through a four-year action-research project in Colombia, Cuba and Chile, we theorize about the production of change by local agents. Through detailed case studies we explored the activism of 17 local leaders. Through narrative analysis we studied their motivations and explanations. Finally, by documenting 22 initiatives, we revealed effective changes in space.

In the face of risk and disasters, residents and leaders in informal settings engaged in symbolic, physical and social spaces of interaction. Their actions were guided by trust, emotions, time cycles and activism. Local agency was justified by narratives about risk and climate change that differ from those of authorities and scholars.

There is still limited understanding of bottom-up initiatives in informal settings. It is crucial to conceptualize their origins, limitations and success. The focus on three specific countries necessitates further research for broader applicability and understanding.

A better comprehension of bottom-up actions is crucial for informing policies and programmes aimed at reducing risk in informal settings. Stakeholders must recognize the political, social and cultural roles of these actions for more impactful climate action.

We borrow Simon’s concept of “artefact” to introduce the notion of “Artefacts of Disaster Risk Reduction”, providing insights into the multifaceted nature of bottom-up initiatives. We also emphasize the simultaneous political and phenomenological character of these actions, contributing to a deeper understanding of their origins and impact.
