This paper focuses on the analysis of two types of identity construction in a corpus of professional speeches, namely institutional identity of the company and professional identity of the speaker. Since the corpus under study is rather large, three interesting speeches are selected on the basis...

Chinese employers practice extensive personal screening of job applicants. This study identifies four manifestations of this practice by motive – statistical, customer taste-based, employer taste-based, and regulatory – and evaluates their prevalence, economic determinants and implications...

Real-life utility networks such as smart grids, pipelines and water networks can be exposed to safety and security related risk. Preventative measures can be applied to mitigate such risks that may result in service interruptions for the users of these networks. An index of (dis)connectivity,...

In this paper, the multiple travelling salesperson problem with hotel selection (m-TSPHS) is presented. This combinatorial optimisation problem is a generalisation of both the travelling salesperson problem with hotel selection (TSPHS) and the multiple travelling salesperson problem (m-TSP). As...

In this paper we present a heuristic framework that is based on mathematical programming to solve network design problems. Our techniques combine local branching with locally exact refinements. In an iterative strategy an existing solution is refined by solving restricted mixed integer programs...

Stated choice experiments are conducted to identify the attributes that drive people's preferences when choosing between competing options of products or services. They are widely used in transportation in order to support the decision making of companies and governmental authorities. A large...

Intermittent power sources enable firms to reduce costs by horizontally subcontracting generation. Dispatchable units serve as a strategic device, even when never used, since their availability credibly limits the price paid for subcontracting. Security of supply measures motivated by too low...

We present an effective scheduling heuristic for realistic production planning in a petrochemical blending plant? The considered model takes into account orders spanning a multi-product portfolio with multiple bills of materials per product, that need to be scheduled on shared production...

Many real-world large datasets correspond to bipartite graph data settings; think for example of users rating movies or people visiting locations. Although some work exists over such bigraphs, no general network-oriented methodology has been proposed yet to perform node classification. In this...

In this paper, a metaheuristic approach is presented to solve the Clustered Vehicle Routing Problem (CluVRP). The CluVRP, in which customers are grouped into predefi?ned clusters, can be seen as a generalisation of the classical Capacitated Vehicle Routing Problem (CVRP). When serving all these...
