Models of electoral competition between two opportunistic, office-motivated parties typically predict that both parties become indistinguishable in equilibrium. I show that this strong connection between the office motivation of parties and their equilibrium choice of identical platforms depends on two possibly false assumptions: 1. Issue spaces are uni-dimensional and 2. Parties are unitary ac...

The state-of-the-art in the area of modelling of organisations is based on fixed metamodels. Due to rapid changing business requirements the complexity in developing applications which deliver business solutions is continually growing. To manage this complexity, environments providing flexible metamodelling capabilities instead of fixed metamodels has shown to be helpful. The main characteristi...

marine industry requires continued development of new technologies in order to produce oil. an essential requirement in design is to be able to compare experimental data from prototype structures with predicted information from a corresponding analytical finite element model. in this study, structural model updating may be defined as the fit of an existing analytical model in the light of measu...

Social platforms are currently encountering a set of burning issues: low ad conversion rates, cross-channel free-riding phenomena, lack monetary incentives to retain premium content creators, etc. Direct purchase behaviors between social platform users (e.g., making direct through seller's promotional post) can largely resolve these problems. Therefore, it is imperative study the factors that i...

We consider the pricing problem of a platform that matches heterogeneous agents using match‐contingent fees. Absent prices, on short side such markets capture relatively greater surplus than those long (Ashlagi et al. 2017). Nevertheless we show need not bias its price allocation toward either side. With independently drawn preferences, optimal decisions are independent market size or imbalance...

because of fluctuation in leg tension, pitch motion is very effective fatigue and life safety of leg elements in tension leg structures (tlss). in this paper an exact solution for pitch vibration of a tls interacting with ocean wave is presented. the legs of tlp are considered as elastic springs. the flow is assumed to be irrotational and single-valued velocity potentials are defined. the effec...
