Foreign Aid Linked to Infrastructure and/or Pollution Abatement

This paper studies the macroeconomic effects of a permanent increase in foreign aid in a model that takes into account environmental quality. We develop a dynamic equilibrium model in which both public investment in infrastructure and environmental protection can be financed using domestic resources and international aid programs. The framework considers four scenarios for international aid: untied aid,aid fully tied to infrastructure, aid fully tied to abatement, and aid equally tied to both types of expenditures. We find that the effects of the transfers may depend on (i) the structural characteristics of the recipient country (the elasticity of substitution in production and its dependence on environment and natural resources) and on (ii) how recipient countries distribute their public expenditure. These results underscore the importance of these factors when deciding how and to what extent to tie aid to infrastructure and/or pollution abatement.

Análisis de la interferencia inducida en el electrocardiograma y señal de impedancia por compresiones torácicas sobre un maniquí.

[EN]This paper presents a project within that research field. The project consists on the development of an experimental environment comprised by a sensorized practice manikin and a management software system. Manikin model allows the simulation of cardiac arrest episodes on laboratory settings. The management software system adds the capacity to compute and analyze the characteristics of the artifact induced on the electrocardiogram and the thoracic impedance signals by chest compressions during cardiopulmonary resuscitation due to variations of the electrode-skin interface. The main reason for choosing this kind of model is the impossibility to use real people because of the risk of thoracic injuries during chest compression. Moreover, this platform could be used for training in reanimation techniques for real situations. Even laypeople with minimal training can perform cardiopulmonary resuscitation. This can reduce the response time to an emergency while the healthcare personnel arrives, which is key to improve outcomes, since with every minute the chances of survival decrease approximately 10%. It is not necessary to have medical knowledge to perform cardiopulmonary resuscitation, which could increase chances of survival for a patient with an early reanimation since In this context, this paper details the technique solution for the manikin sensorisation to acquire the electrocardiogram, the impedance signal measured between the defibrillation pads placed on the patient’s chest, the compression depth, the compression force and the acceleration experienced by the chest in the three orthogonal axes. Moreover, it is possible to inject a previously recorded electrocardiogram signal.

MW, Medical Watches

My project is a business plan about the set up of a company and the development of a new and innovative product aimed for the elders. I decide do this project when I discover that one of the more important needs that have the elders is to remember the medicines that they have to take. I thought that a good way could be through a smart watch. My watch have an only function, is a cheap device, easy to use, easy to understand and easy to set up, because the elders usually do not know to use complex electronics devices. There are other similar smart watches and other devices but do not have the necessary characteristics to be a good reminder for elders. My watch is centred to improve the life of the elders, but my product could also be useful for ill people who have to take many medicines during the day. After realizing this business plan, I have proved that my company is viable in the environment and profitable in the market.

Towards Application of One-Class Classification Methods to Medical Data

In the problem of one-class classification (OCC) one of the classes, the target class, has to be distinguished from all other possible objects, considered as nontargets. In many biomedical problems this situation arises, for example, in diagnosis, image based tumor recognition or analysis of electrocardiogram data. In this paper an approach to OCC based on a typicality test is experimentally compared with reference state-of-the-art OCC techniques-Gaussian, mixture of Gaussians, naive Parzen, Parzen, and support vector data description-using biomedical data sets. We evaluate the ability of the procedures using twelve experimental data sets with not necessarily continuous data. As there are few benchmark data sets for one-class classification, all data sets considered in the evaluation have multiple classes. Each class in turn is considered as the target class and the units in the other classes are considered as new units to be classified. The results of the comparison show the good performance of the typicality approach, which is available for high dimensional data; it is worth mentioning that it can be used for any kind of data (continuous, discrete, or nominal), whereas state-of-the-art approaches application is not straightforward when nominal variables are present.
