The management of sponsorship in a non-profit organisation

This research project is focused on providing an exploration of a non-profit organisation recognised all over the world. The investigation is focused on understanding the sponsorship management processes used by the organisation. The method chosen for this research was qualitative data. Two interviews were conducted to obtain information from the main source. Interviews were chosen because they allow investigating issues in an in-depth way. Moreover, they allow more detailed questions to be asked and incomplete answers or ambiguities can be clarified and interviewees are not influenced by others in the group. Limitations and findings are discussed, along with recommendations for future research. The results conclude with recommendations

Information Spreading on Almost Torus Networks

Epidemic modeling has been extensively used in the last years in the field of telecommunications and computer networks. We consider the popular Susceptible-Infected-Susceptible spreading model as the metric for information spreading. In this work, we analyze information spreading on a particular class of networks denoted almost torus networks and over the lattice which can be considered as the limit when the torus length goes to infinity. Almost torus networks consist on the torus network topology where some nodes or edges have been removed. We find explicit expressions for the characteristic polynomial of these graphs and tight lower bounds for its computation. These expressions allow us to estimate their spectral radius and thus how the information spreads on these networks

Defensive Resource Allocation in Social Networks

In this work, we are interested on the analysis of competing marketing campaigns between an incumbent who dominates the market and a challenger who wants to enter the market. We are interested in (a) the simultaneous decision of how many resources to allocate to their potential customers to advertise their products for both marketing campaigns, and (b) the optimal allocation on the situation in which the incumbent knows the entrance of the challenger and thus can predict its response. Applying results from game theory, we characterize these optimal strategic resource allocations for the voter model of social networks.Comment: arXiv admin note: text overlap with arXiv:1402.538

Determining plane curve singularities from its polars

This paper addresses a very classical topic that goes back at least to Pl\"ucker: how to understand a plane curve singularity using its polar curves. Here, we explicitly construct the singular points of a plane curve singularity directly from the weighted cluster of base points of its polars. In particular, we determine the equisingularity class (or topological equivalence class) of a germ of plane curve from the equisingularity class of generic polars and combinatorial data about the non-singular points shared by them.Comment: 22 pages.

Strategic Procurement, Openness and Market Structure

We examine strategic procurement behaviour by governments and its effect on market structure in sectors, such as defence, where the government is the dominant consumer. In a world economy with trade between producers, and between producers and non-producers, we use a modified Dixit-Stiglitz utility function with an indepen- dent taste for variety. Governments can, in effect, choose the number of domestic firms and their size by adjusting the procurement price. Unlike the standard model with no independent taste for variety and no external sector of non-producers, there are incentives for subsidies, openness impacts on industrial structure and there are potential gains from procurement coordination between producer countries.procurement, openness, market structure, defence and pharmaceutical sectors

Parallel imports, innovations and national welfare: The role of the sizes of the income classes and national markets for health care.

This paper shows that regardless of any intra-country income differences, parallel imports result in a lower level of health-care innovation but, contrary to popular as well as conventional theoretical wisdom, a lower price in the Third World compared to market-based discrimination. Despite such a lower price, however, parallel imports unambiguously make all buyers in the Third World worse off when intra-country income disparity exists. On the other hand, even discarding the MNC's profit, there will be cases in which the richer country prefers price discrimination as well. That is, in those cases, no countries will have any incentive under the welfare criterion to undo price discrimination, contrary to Richardso

Aiming at reducing cost and grid energy consumption, in the present paper, we study RE exchange (REE) possibilities in late-trend network deployments of energy harvesting (EH) macrocell and small cell base stations (EH-MBSs, EH-SBSs) that use an EH system, an energy storage system, and the smart grid as energy procurement sources. On this basis, we study a two-tier network composed of EH-MBSs that are passively shared among a set of mobile network operators (MNOs), and EH-SBSs that are provided to MNOs by an infrastructure provider (InP). Taking into consideration the infrastructure location and the variety of stakeholders involved in the network deployment, we propose as REE approaches 1) a cooperative RE sharing, based on bankruptcy theory, for the shared EH-MBSs and 2) a non-cooperative, aggregator-assisted RE trading, which uses double auctions to describe the REE acts among the InP provided EH-SBSs managed by different MNOs, after an initial internal REE among the ones managed by a single MNO. Our results display that our proposals outperform baseline approaches, providing a considerable reduction in SG energy utilization and costs, with satisfaction of the participant parties.Peer ReviewedPostprint (author's final draft

Repasivation of steel rebars after and electrochemical chlorides removal treatment by simultaneous application of calcium nitrite

The Electrochemical Removal of Chlorides (CE) can be proposed as methodology for the treatment of reinforced concrete structures affected by corrosion. This methodology is based on the temporary application of an external voltage between an external anode located on the concrete and the rebar connected as cathode. After the treatment, the extraction of chloride from the concrete level and the repassivation of the rebar are expected. The migration of ionic inhibitors to the rebar could be considered during the connection of an electric field to favour the regeneration of the passive film. In present work a novel methodology is proposed to enhance the efficiency of an Electrochemical Chloride Extraction treatment by simultaneous application of calcium nitrite. A fast repassivation of the rebar is reached after the CE treatment when the inhibitor is applied during the electric field connection. The penetration of the inhibitor near the rebar surface has been confirmed by. The new passive conditions of the steel rebar after the treatment were confirmed by electrochemical measurements. The penetration of the inhibitor near the rebar surface was assured by analysing of nitrite dissolved into the aqueous phase. The presence of nitrite promoted a faster regeneration of the passive film that is maintained in time
