State Failure in Developing Countries and Strategies of Institutional Reform”, paper presented at the ABCDE Conference Europe
, 2002
"... Abstract: The analysis of state failure and the policy debate have been driven by two very different underlying views of what the state does. The first, which we call the “service-delivery ” view says the role of the state is to provide law and order, stable property rights, key public goods and we ..."

and welfarist redistributions. In failing to provide these, state failure contributes to economic under-performance and poverty. State failure of this type is in turn related to an inter-dependent constellation of governance failures including corruption and rent-seeking, distortions in markets and the absence
A Probabilistic Study of Inter-Satellite Links Load in Polar Orbit Satellite Constellations
"... We analyze the load of the inter-satellite links in polar satellite constellations. Starting from simple considerations on the structure of the underlying network topology, we derive the probability of use of different families of links, with various hypotheses on the nature of the traffic. Our anal ..."

"... Abstract—In this paper we consider the use of non-uniform QAM constellations (Quadrature Amplitude Modulation) for broadcast or multicast transmissions within WCDMA-based systems (Wideband Code Division Multiple Access). These constellations are employed so as to increase the transmission efficiency ..."

relevant information will only be extracted by users with good propagation conditions. However, these constellations are very sensitive to inter-symbolic interference introduced by multipath propagation, especially for large constellations. Moreover, large non-uniform constellations are also very sensitive
Exploration of the Local Distribution of Major Ethnic Groups in the USA
"... Knowledge about the local distribution of major ethnic groups in the USA is an important source of information upon which the success of political and economic decisions may depend. Enhancing this information with additional attributes, such as the specific income or spoken languages, reveals intere ..."

interesting aspects on social constellations as well as their interdependencies. The presented visualization facilitates the intuitive exploration of such multidimensional data sets with references to geographical units. Thus, a quick insight into the inherent patterns and characteristic features is provided
Towards a Dynamic Combinatorial Dictionary: A Proposal for Introducing Interactions between Collocations in an Electronic Dictionary of English Word Combinations
"... This paper presents an academic (non-commercial) lexicographic project called Dynamic Combinatorial Dictionary, which is currently being developed by members of the LACELL Research Group at the University of Murcia. The aim of this project is to bring e-Lexicography in closer alignment with lexical ..."

within the same collocational window. We will distinguish two different manifestations of this multiplicity of domains. The first one is the phenomenon of indirect collocation, which has been investigated in previous Lexical Constellation research, and the second one is inter-collocability. This concept

"... objective is to measure the fundamental parameters of ionosphereic density irregularities that effect radio wave propagation including communications, navigation, and the Global Positioning System. This data will also be used in the development and validation of global ionospheric models. Student te ..."

teams, with direction from faculty and professionals, are designing and building these 15kg three axis stabilized satellites. The satellites will fly as a string of beads, with varying inter-satellite separation, over an approximate one-year mission. Two of the satellites incorporate propulsion systems
On the Reliability, Validity, and Cognitive Structure of the Thurstone Word Fluency Test
"... The Thurstone Word Fluency Test (TWFT) is a widely used neuropsychological instrument. However, data regarding its psychometric properties are lacking. The results of the present study suggest that the TWFT possesses excellent test-retest and inter-rater reliability, in addition to good construct va ..."

Single-Block Coded Modulation for MIMO Systems
"... Abstract—This paper introduces a new class of space-time codes that achieve coding gain without a trellis or any form of inter-block dependency. The construction of the new codes starts from an existing (parent) space-time block code (STBC). Then by increasing the constellation size followed by expu ..."
