We consider the inventory decision of a retailer facing strategic customers. We develop a behavioral theory that accounts for reference dependence, which makes predictions on how the presence of strategic customers leverages retailer behavior. Specifically, the reference-dependent retailer shall decrease her order quantity when there are more strategic customers in the population. As such, the conventional pull-to-center bias for newsvendor is generalized, since the presence of strategic consumers may induce the retailer to pull her order further below the center even when the production cost is low. Furthermore, increasing proportion of strategic customers reduces the retailer's ordering bias under low cost, yet amplifies it when the cost is high. Our subsequent experiments find pull-below-center effect, validate the theoretical predictions, and establish the asymmetry of reference dependence with the estimated behavioral parameters. We also study extensions to our model and carry out robustness checks of our experimental results. [less ▲]

This Inventory of institutional sources consulted is an output of the major research project dedicated to the European vocation and achievements of Pierre Werner, a former Prime Minister, Finance Minister and Foreign Minister of Luxembourg, unanimously recognised as one of the architects of Economic and Monetary Union. The first stage of the research was particularly focused on the plan for the establishment by stages of an economic and monetary union (more widely known as the Werner Report or the Werner Plan), drawn up by a group of experts chaired by Pierre Werner and officially presented on 8 October 1970 in Luxembourg.

In this chapter we develop an indirect approach for assessing criteria significance weights from the robustness of the significance that a decision maker acknowledges for his pairwise outranking statements in a Multiple Criteria Decision Aiding process. The main result consists in showing that with the help of a mixed integer linear programming model this kind of a priori knowledge is sufficient for estimating adequate numerical significance weights.

BACKGROUND: Coagulation and prothrombotic potential have genuinely been associated with increased cardiovascular risk. However, not all studies in this regard are conclusive. Some clinical trials have shown an increased frequency of cardiovascular complications in patients receiving direct thrombin inhibitors. Previous data from human subjects after acute cardiovascular events showed an inverse association between the thrombin generation marker F1+2 and cardiovascular endpoints indicating that not the lowest, but a slightly elevated propensity for thrombin generation is associated with a lower risk of cardiovascular events. This observation has been supported by findings in animal models of atherosclerosis. Hence, we evaluated the association between the endogenous thrombin potential (ETP) and cardiovascular death (CVD) and markers of vascular dysfunction in a large prospective study with long-term follow up. METHOD: After excluding patients receiving anticoagulants we tested ETP in 2196 participants (median follow-up 10 years) for its ability to predict vascular death (CVD). In addition, the association between ETP and sVCAM-1, sICAM-1, LpPLA2, hsCRP and SAA was determined. RESULTS: We observed an inverse association between ETP and CVD with the lowest hazard ratio in the 4th ETP quartile. The nadirs of sICAM-1 or sVCAM-1 were observed in the 3rd, for LpPLA2 in the 4th ETP quartile. Conversely, hsCRP and SAA were highest in the 4th quartile. CONCLUSIONS: These results demonstrate that not the lowest ETP possible, but slightly higher levels are associated with a reduced risk of CVD and lower markers of endothelial dysfunction, suggesting a more complex role of thrombin in cardiovascular disease.

This note addresses identification of the A-matrix in continuous time linear dynamical systems on state-space form. If this matrix is partially known or known to have a sparse structure, such knowledge can be used to simplify the identification. We begin by introducing some general conditions for solvability of the inverse problems for matrix exponential. Next, we introduce “system aliasing” as an issue in the identification of slow sampled systems. Such aliasing give rise to nonunique matrix logarithms. As we show, by imposing additional conditions on and prior knowledge about the A-matrix, the issue of system aliasing can, at least partially, be overcome. Under conditions on the sparsity and the norm of the A-matrix, it is identifiable up to a finite equivalence class. [less ▲]

In a single case study, we show how a conversation analysis (CA) approach can shed light onto the sequential unfolding of human-robot interaction. Relying on video data, we are able to show that CA allows us to investigate the respective turn-taking systems of humans and a NAO robot in their dialogical dynamics, thus pointing out relevant differences. Our fine grained video analysis points out occurring breakdowns and their overcoming when humans and a NAO-robot engage in a multimodally uttered multi-party communication during a sports guessing game. Our findings suggest that interdisciplinary work opens up the opportunity to gain new insights into the challenging issues of human robot communication in order to provide resources for developing mechanisms that enable complex HRI.

The existence of multiphase flows through packed bed of solid particles in broad spectrum of engineering disciplines such as chemical industries, petroleum engineering, wastewater treatment is undeniable. One frequently used reactor of this type is a trickle bed reactor that usually contains particulate phase of which the interstitial space is filled with gas and liquid phases. Based on the direction of the fluid flow they can be classified as cocurrent downflow trickle bed reactors, counter-current trickle bed reactors and cocurrent upflow packed bubble reactors. In these kind of problems numerical simulations can help to gain a better process understanding. In the current distribution, a numerical method so called Extended Discrete Element Method (XDEM) was applied to model multiphase flow through packed bed of solid particles which has the ability to be coupled to Computational Fluid Dynamics (CFD) through interphase momentum transfer. In this coupled solver the fluid phases are treated by CFD while the position and orientation of the particles in each CFD cell and the porosity distribution through packed bed are provided by XDEM. In order to validate the code, two important hydrodynamic parameters such as pressure drop and liquid hold up were investigated and satisfactory agreement between predicted and experimental data was achieved. The model results demonstrate enormous effect of solid particles on the deviation of fluid phases while passing through packed bed by investigating parameters such as velocity and drag force.
