The issue of the paper is how to characterize public e-services mediated through the web. One common kind of characterization is made through stage models (e-ladders). Such models are frequently used for policy-planning, evaluation and bench-marking of public e-services. E-ladder models have been criticized and as an alternative the e-diamond model has been formulated, which consists of twelve ...

This paper examines some standard open-economy New Keynesian models to address the question of how globalisation affects the inflation process. Specifically, it investigates how the Phillips curve for consumer price inflation in a country is affected by openness, and how the optimal choice of monetary policy is influenced by openness. The paper compares models that assume producer currency pric...

The game of football demands new computational approaches to measure individual and collective performance. Understanding the phenomena involved in the game may foster the identification of strengths and weaknesses, not only of each player, but also of the whole team. The development of assertive quantitative methodologies constitutes a key element in sports training. In football, the predictab...

In this paper, we propose a refinement of Chevallard’s algebraic modeling while still fully agreeing with his position that it is a key process in knowing mathematics. In doing so, based on our empirical study, we claim that: 1) there are two other stages in the algebraic modeling process; 2) it is nonlinear; and 3) partial models are constructed as well. Research on Chevallard's modeling persp...

We present a novel and fast algorithm to solve the Perspective-n-Point problem. The PnP problem estimating the pose of a calibrated camera based on measurements and known 3D scene, is recasted as a minimization problem of the Object Space Cost. Instead of limiting the algorithm to perspective cameras, we use a formulation for general camera models. The minimization problem, together with a quat...

Generalizing a result of Furstenberg, we show that for every infinite discrete group $G$, the Bernoulli flow $2^G$ is disjoint from minimal $G$-flow. From this, deduce algebra generated by functions $\mathfrak{A}(G)$ proper subalgebra $\ell^\infty(G)$ and enveloping semigroup universal $M(G)$ quotient $\beta G$. When $G$ countable, also prove any metrizable, $G$-flow, there exists free, it exis...

This paper has been prepared based on secondary data. The China and Bangladesh diplomatic relations were established in 1975. Since then, the relationship between going high. China-Bangladesh reached a new level with China's President Xi Jinping's two-day historic visit to October 2016. Which was widely dubbed "historic state visit," start of "new horizon," or "a historical starting point" rela...

In this paper the architecture and implementation of Cooperative Information Agents (CIA) is described. Taking a language-action perspective to the design of CIAs allows for the specification of obligations and authorizations, and results in the separation of tasks (things the agentmust do) and contracts (mutually agreed commitments to the course of communication). The architecture describes th...

Good communication is the basis for effective cooperation. An area where cooperation is essential is multidisciplinary healthcare. In this paper we will present a research project that aims at promoting effective multidisciplinary communication in a healthcare environment. We will answer the question of whether empirical modelling of the communication and cooperation patterns can be done based ...

When people or organizations provide information, they make choices regarding what they include and how they represent it. These two aspects combined (the content and the stance) represent a perspective. Investigating perspectives can provide useful insights into the reliability of information, changes in viewpoints over time, shared beliefs among social or political groups and contrasts with o...
