New Trends in Urban Drainage Modelling

2019

This book addresses the latest research advances, innovations, and applications in the field of urban drainage and water management as presented by leading researchers, scientists and practitioners from around the world at the 11th International Conference on Urban Drainage Modelling (UDM), held in Palermo, Italy from 23 to 26 September, 2018. The conference was promoted and organized by the University of Palermo, Italy and the International Working Group on Data and Models, with the support of four of the world’s leading organizations in the water sector: the International Water Association (IWA), International Association for Hydro-Environment Engineering and Research (IAHR), Environmenta…

Urban runoff modelling uncertainty: Comparison among Bayesian and pseudo-Bayesian methods

2009

Urban stormwater quality modelling plays a central role in evaluation of the quality of the receiving water body. However, the complexity of the physical processes that must be simulated and the limited amount of data available for calibration may lead to high uncertainty in the model results. This study was conducted to assess modelling uncertainty associated with catchment surface pollution evaluation. Eight models were compared based on the results of a case study in which there was limited data available for calibration. Uncertainty analysis was then conducted using three different methods: the Bayesian Monte Carlo method, the GLUE pseudo-Bayesian method and the GLUE method revised by m…

Understanding the purchasing behavior of consumers in response to sustainable marketing practices: An empirical analysis in the food domain

2021

Sustainability has become an important driver in defining business strategies, affecting most critical corporate functions and changing the way in which value is created, communicated, and distributed. This is increasingly impacting marketing practices, in particular, through promoting the development of sustainable marketing in the food sector. In line with this, our study aimed to investigate if and how sustainable marketing practices affect consumer loyalty to a specific brand. To answer our research questions, we relied on the results of a survey submitted to a sample of 907 Italian consumers of biscuits. Results showed that the consumers’ attention to sustainable issues (in the absence…

Reward-based crowdfunding campaigns: Informational value and access to venture capital

2018

We consider an entrepreneur who designs a reward-based crowdfunding campaign when the campaign provides a signal about the future demand for the product and subsequent venture capital is needed. We find that both the informativeness of the campaign and considerations related to gaining access to venture capital funding affect the entrepreneur’s choice of campaign instruments, as well as her decision of whether to run a campaign. In particular, entrepreneurs should launch the campaign either when it is highly informative or when it is not informative at all. For relatively low levels of informativeness, but not so low that the venture capitalist (VC) completely ignores the campaign outcome …

The relationship between Value Co-creation and Defensive Medicine

The purpose of this study is to analyse the patient-physician relationship from the perspective of its consequences in terms of risk of defensive medicine behaviour and of likelihood of value co-creation occurrence. We develop, first, a theoretically informed model which explains the patient-physician relationship in terms of the two phenomena above mentioned; we then collect qualitative empirical data, elaborate on the theory, and develop an empirically informed model. The main result of this research is the definition of four archetypes of the patient-physician relationship, whose discussion leads to theoretical contributions and managerial implications.

Networking strategy as a strategic management tool

2011

Many research studies in operations and strategic management have investigated how different kinds of decisions regarding business relationships can positively affect firm’s operations performance, resources endowment, and competitive position. Very few studies exist trying to illuminate the actual behavior of managers when making strategic decisions concerning their company relationships with other companies as opposed to normative theory. By collecting data from 13 business agreements from 3 firms, the purpose of this paper is explore linkages between the “set” of strategic objectives that managers are willing to pursue and the “set” of networking decisions that they actually consider whe…

What to show on the wine labels: a hedonic analysis of price drivers of Sicilian wines

2013

Unlike previous literature, we construct a hedonic model of wine price that incorporates all the main categories of variables simultaneously to enable a better evaluation of their importance on wine price formation. A comprehensive model has the advantage of providing more reliable estimates of the attributes' implicit prices thereby facilitating firms' pricing and improving effectiveness of wine production and marketing decisions. We utilize two different datasets of Sicilian wines collecting data from influential wine guides. Our results suggest that wine price strongly depends on objective features such as vintage, alcoholic content, geographical origin, grape variety, producer size and …

Aerobic granular sludge reactor treating anaerobically pretreated brewery wastewater at different loading rates

2018

Small and medium breweries discharging to municipal sewers without treatment generate significant loads with typical concentrations reported by Valta et al. (2014) as 2-6 g COD L-1, 25-80 mg TN L-1, 10-50 mg TP L-1, with pH between 4.5 and 12. Treatment of the high-strength wastewater requires specialized low footprint processes, such as aerobic granular sludge (AGS), capable of high-rate degradation, as well as simultaneous nitrogen and phosphorous removal (Wang et al., 2007). The objective of this study was to evaluate the start-up period of AGS receiving brewery wastewater after initial anaerobic pretreatment.

Interpreting and modelling field data for wastewater dispersion into sea through dimensional analysis

Role of modeling uncertainty in the estimation of climate and socioeconomic impact on river water quality. J. of Water Resources Planning and Managem…

2012

Climate is one of the most important factors leading to changes in the hydrologic and environmental characteristics of river basins. When considering water quality, the natural factors should be weighed against anthropogenic factors (such as urbanization, increased population, and higher water demand) that may increase or decrease the effect of climatic modifications. Any prediction of future climatic and anthropogenic scenarios is affected by uncertainty and the modelling tools that are used for evaluating their impact on receiving water bodies. The present paper is aimed at investigating the complexity of such analyses and the uncertainty related to future impact predictions based on limi…
