This paper uses a tailor-made newly available data set for enterprises from manufacturing industries in Germany to investigate for the first time the links between export diversification over destination countries and goods on the one hand and the profitability of the exporting firms on the other hand. We find that profits tend to be larger in firms with less diversified export sales over goods...

In this study, we analyzed an intra-cluster based cooperative energy detection between source (S) and destination (D), the network model consisting of one source, one destination and M number of clusters between the source and destination and each cluster consisting of N number of cognitive relays. We analyzed the performance of inter-cluster and intra-cluster cooperative energy detection. We d...

BACKGROUND International recruitment is a common strategy used by high-income countries to meet their medical workforce needs. Ireland, despite training sufficient doctors to meet its internal demand, continues to be heavily dependent on foreign-trained doctors, many of whom may migrate onwards to new destination countries. A cross-sectional study was conducted to measure and analyse the factor...

The Role of Income and Immigration Policies in Attracting International Migrants This paper makes two contributions to the literature on the determinants of international migration flows. First, we compile a new dataset on annual bilateral migration flows covering 15 OECD destination countries and 120 sending countries for the period 1980-2006. We also collect data on time-varying immigration p...

This paper examines the role of migration-specific and migration-relevant policies in migrant decisionmaking factors for onwards migration or stay in Greece and Turkey. In this paper we distinguish migration-specific policies from migration-relevant policies in transit and destination countries, and in each case distinguish favourable policies from adverse policies. We test this categorisation ...

This thesis deals with the design of efficient transmission schemes for wireless interference networks, when certain channel state information (CSI) is available at the terminals. In wireless interference networks multiple source-destination pairs share the same transmission medium for the communications. The signal reception at each destination is affected by the interference from unintended s...

--Performance degradation is an major problem in a relay based Decode-and-Forward (DF) receiving cooperative system. In the DF protocol , existing decoder performances have high decoding complexity, because destination require exact knowledge of the sourcerelay link along with the channel coefficient of source-destination and relay –destination links. In the proposed method, degradation can be ...

Graph-based techniques and analysis have been used for IP network traffic analysis. The objective of this paper is to study the hosts' interaction behavior and use graph clustering algorithm, the Markov clustering algorithm, to group (cluster) hosts which have interaction using the HTTP protocol. Using real network traces, the clustering results show that MCL algorithm successfully group t...

BACKGROUND There is growing concern globally at the current flows of nurse migration, particularly from low-income to middle and high-income countries. Recruitment practices of many countries such as Ireland are thought to be fuelling this rate of migration. This paper aims to establish the perceptions and opinions of those involved in the recruitment process on their role in recruitment and th...
