The dial-a-ride problem with electric vehicles and battery swapping stations

The Dial-a-Ride Problem (DARP) consists of designing vehicle routes and schedules for customers with special needs and/or disabilities. The DARP with Electric Vehicles and battery swapping stations (DARP-EV) concerns scheduling a fleet of EVs to serve a set of pre-specified transport requests during a certain planning horizon. In addition, EVs can be recharged by swapping their…

Combining behavioral approaches with techno-economic energy models ::dealing with the coupling non-linearity issue

Consumer behaviour is often complex and even sometimes not economically rational. Wrongly, the first techno-economic energy planning models assumed the economic rationality hypothesis and, therefore, represented consumers’ behaviour incorrectly. Nevertheless, the current trend is to couple these models with behavioural approaches that were specially developed to describe the real…

Hot markets, underpricing and underperformance: IPO anomalies under the light of modern risk factors

This paper investigates to which extent multifactor asset pricing models can explain the pricing of IPOs in the U.S. market between 1980 and 2015. The paper contributes to the existing literature by demonstrating that the hot market, the underpricing and the underperformance issues can be explained by the general trends and the intensities of various risk factors. We analyse the…

Does leverage impair earnings quality in the hospitality industry?: international evidence

We investigate the determinants of leverage and the impact of leverage on earnings quality using a large sample of public firms incorporated in 24 countries, from five hospitality sub-industries (bars and restaurants, gambling, hotels, recreational services, and travel and tourism), over the 2000-2016 period. First, we show that firm-specific characteristics (size, tangibility, and…

Weighted forensics evidence using blockchain

When digital evidence is presented in front of a court of law, it is seldom associated with a scientific evaluation of its relevance, or significance. When experts are challenged about the validity of the digital evidence, the general answer is “yes, to a reasonable degree of scientific certainty”. Which means all and nothing at the same time, since no scientific metric is…

On the properties of high-order non-monetary measures for risks

This paper investigates how welfare losses for facing high-order risk increases change when the risk environment of the decision maker is altered. To that aim, we define the nth-order utility premium as a measure of pain associated with facing the passage of one risk to a more severe one and we examine some of its properties. Changes in risk are expressed through the concept of…

A semi-Lagrangian splitting method for the numerical simulation of sediment transport with free surface flows

We present a numerical model for the simulation of 3D poly-dispersed sediment transport in a Newtonian flow with free surfaces. The physical model is based on a mixture model for multiphase flows. The Navier–Stokes equations are coupled with the transport and deposition of the particle concentrations, and a volume-of-fluid approach to track the free surface between water and air. The…

A least-squares/relaxation method for the numerical solution of the three-dimensional elliptic Monge–Ampère equation

In this article, we address the numerical solution of the Dirichlet problem for the three-dimensional elliptic Monge–Ampère equation using a least-squares/relaxation approach. The relaxation algorithm allows the decoupling of the differential operators from the nonlinearities. Dedicated numerical solvers are derived for the efficient solution of the local optimization problems with…

A study on the heterogeneous fleet of alternative fuel vehicles ::reducing CO2 emissions by means of biodiesel fuel

In the context of home healthcare services, patients may need to be visited multiple times by different healthcare specialists who may use a fleet of heterogeneous vehicles. In addition, some of these visits may need to be synchronized with each other for performing a treatment at the same time. We call this problem the Heterogeneous Fleet Vehicle Routing Problem with Synchronized…

Accelerators: an assessment of acceleration models

Accelerators assist early-stage ventures by offering networking opportunities, access to funding and training. We map business accelerators in five categories: Independent Accelerators (IA), Corporate Accelerators (CA), Hybrid Accelerators (HA), University Accelerators (UA), and Government Accelerators (GA). We argue that accelerators can be described by two main acceleration models…

The role of angel investor identity in entrepreneurship

Grounded on social identity theory, we explore the identities and actions of 41 angel investors who invest in early-stage companies in the field of ICT. Our study reveals the existence of four pure types of angel investor identities and suggests how these identities shape their investment behavior and consequent exchange of resources with investees. We summarize our results in a…

Digital feedback: : a multimodal approach to feedback for learning

Digital tools provide educators with a platform to deliver feedback in a multi-modal manner, which can be particularly useful for qualitative student work. This paper explores how delivering student feedback with a multimodal digital approach through screen casting is a way to enhance formative assessment for learning. The purpose of this work is to briefly survey the literature on…

Program understanding using ontologies and dynamic analysis

No maintenance activity can be performed without understanding at least the part of the program that needs to b emodified. Therefore, considering its cost, helping developers to understand programs is a must. Consequently, our research aims at building a business related model of the program semantics, which is grounded in Perkinsfi research in psychology. After a short reminder of…

Is taxing waste a waste of time?: evidence from a Supreme Court decision

Environmental taxes are often underexploited. This paper analyses the effectiveness of a garbage tax, assessing its effects on multiple outcomes as well as its acceptability. We study how a Supreme Court decision, mandating the Swiss Canton of Vaud to implement a tax on garbage, affects garbage production and beliefs about the tax. We adopt a difference-in-differences approach…
