Parásitos gastrointestinales como indicadores en vizcacha

Los parásitos son importantes indicadores de distintos aspectos bioecológicos de sus poblaciones hospedadores. Los helmintos son uno de los marcadores biológicos más reconocidos. Se caracterizaron las comunidades de helmintos gastrointestinales en poblaciones continentales e insulares de vizcacha. El objetivo de este trabajo es analizar las comunidades de parásitos gastrointestinales asociadas a poblaciones continentales e insulares de vizcacha en el sudoeste bonaerense y utilizar esta información como indicador del estado de las poblaciones y de su de su posible conexión a través de la migración de individuos.Área: Ciencias Biológicas, Ambiente y Salu

Developing and evaluating a five minute phishing awareness video

Confidence tricksters have always defrauded the unwary. The computer era has merely extended their range and made it possible for them to target anyone in the world who has an email address. Nowadays, they send phishing messages that are specially crafted to deceive. Improving user awareness has the potential to reduce their effectiveness. We have previously developed and empirically-validated phishing awareness programmes. Our programmes are specifically designed to neutralize common phish-related misconceptions and teach people how to detect phishes. Many companies and individuals are already using our programmes, but a persistent niggle has been the amount of time required to complete the awareness programme. This paper reports on how we responded by developing and evaluating a condensed phishing awareness video that delivered phishing awareness more efficiently. Having watched our video, participants in our evaluation were able to detect phishing messages significantly more reliably right after watching the video (compared to before watching the video). This ability was also demonstrated after a retention period of eight weeks after first watching the video

OpenCoesione and Monithon - a Transparency Effort

Context OpenCoesione is the first portal about the fulfilment of investments and projects planned by the Italian central government and by the Italian Regions using the 2007­2013 European Cohesion funds. Together with Monithon, it is a “transparency tool” whose aim is to foster participation of the citizens and efficiency of the public sector bodies in order to improve the implementation of development policies. By now it is one of the best Open Data portal in Italy quality­wise. Objective Our goal is to show the utility of these portals, how this open information is supposed to help the civil society and how data quality might affect reuse. Method We engage in the empirical observation on how data are exposed and used, discussing specific examples, and applying some data quality metrics. Results We present some evidences on how open data can positively affect the public sector bodies and the spending of funds. Conclusions Under­spending of EU Cohesion funds is a serious problem in Italy. OpenCoesione and Monithon can contribute solving this inefficiency, e.g., by presenting data in such a (standardised) way to enable their elaboration by third partie

The comparison of latero-medial versus dorso-palmar/plantar drilling for cartilage removal in the proximal interphalangeal joint

The aims of the present study were to compare the percentages of articular cartilage removed using a lateral drilling approach of the proximal interphalangeal joint (PIPJ) and a dorsal drilling approach, and to assess the usefulness of digital fluoroscopy when performing a lateral drilling approach. Sixty cadaveric PIPJs were drilled using a surgical drill bit to remove the articular cartilage. The limbs were divided into three groups containing 10 forelimbs and 10 hindlimbs each. One group received the dorsal drilling approach, the second one received the lateral drilling approach and the last one received the lateral drilling approach under digital fluoroscopy guidance. The percentage of articular cartilage removed from each articular surface was assessed using Adobe Photoshop® software. The percentages of removed cartilage turned out to be significantly higher with lateral approach, especially under fluoroscopic guidance, both in the forelimbs (p = 0.00712) and hindlimbs (p = 0.00962). In conclusion, the lateral drilling approach seems to be a minimally invasive technique with which to perform PIPJ arthrodesis, even more efficient than the previously reported dorsal approach

Efficient aberrations pre-compensation and wavefront correction with a deformable mirror in the middle of a petawatt-class CPA laser system

AbstractIn this paper, we describe the experimental validation of the technique of correction of wavefront aberration in the middle of the laser amplifying chain. This technique allows the correction of the aberrations from the first part of the laser system, and the pre-compensation of the aberrations built in the second part. This approach will allow an effective aberration management in the laser chain, to protect the optical surfaces and optimize performances, and is the only possible approach for multi-petawatt laser system from the technical and economical point of view. This approach is now possible after the introduction of new deformable mirrors with lower static aberrations and higher dynamic than the standard devices

Evaluation of a DSGE Model of Energy in the United Kingdom Using Stationary Data

I examine the impact of energy price shock (oil prices shock and gas prices shock) on the economic activities in the United Kingdom using a dynamic stochastic general equilibrium model with a New Keynesian Philips Curve. I decomposed the changes in output caused by all of the stationary structural shocks. I found that the fall in output during the financial crisis period is driven by domestic demand shock, energy prices shock and world demand shock. I found the energy prices shock’s contribution to fall in output is temporary. Such that, the UK can borrow against such a temporary fall. This estimated model can create additional input to the policymaker’s choice of models
