Hysteresis and labour market institutions. Evidence from the UK and the Netherlands

This paper uses data for the UK and the Netherlands (1983q4–2011q4) to test if hysteresis occurs in these economies, and through what mechanisms. The novelty of the paper resides in the use of a VAR-IRF that encompasses previous hysteresis studies, using long-term unemployment, productivity, capital stock and real long-term interest rates, and in the use of specific Labour Market Institutions shocks, such as benefits, taxation or unions’ power. This allows us to disentangle what specific demand and supply-variables affect unemployment in the long-run, i.e. the NAIRU. Our findings suggest that there is hysteresis in both countries, and that it happens through several channels. Further, we find that the influence of Labour Market Institutions on unemployment depend on their impact on the real wages-productivity gap. These results have implications for structural and macroeconomic policies that we also discuss. Finally, we investigate the impact of different supply and demand-shock on long-term unemployment and discuss the relevant policy implications

Trend in statistical research productivity by journal publications over the period 1985-1997

This work presents a descriptive analysis of the dynamic evolution of statistical research productivity over the period 1985-1997. Research productivity is measured by using the volume of articles published in a set of journals with high impact index. We analyze the productivity trends in the thirty most productive countries and in the twenty top institutions of United States, Europe and the rest of the world

Water-ice driven activity on Main-Belt Comet P/2010 A2 (LINEAR) ?

The dust ejecta of Main-Belt Comet P/2010 A2 (LINEAR) have been observed with several telescopes at the at the Observatorio del Roque de los Muchachos on La Palma, Spain. Application of an inverse dust tail Monte Carlo method to the images of the dust ejecta from the object indicates that a sustained, likely water-ice driven, activity over some eight months is the mechanism responsible for the formation of the observed tail. The total amount of dust released is estimated to be 5E7 kg, which represents about 0.3% of the nucleus mass. While the event could have been triggered by a collision, this cannot be decided from the currently available data.Comment: Accepted for ApJ Letter

Unconventional OFF–ON Response of a Mono(calix[4]arene)-Substituted BODIPY Sensor for Hg2+ through Dimerization Reversion

A new selective fluorogenic chemosensor for Hg2+, which combines a calixarene derivative with a BODIPY core as a fluorescent reporter, is described. The remarkable change in its fluorogenic properties in DMSO and CHCl3 has been analyzed. A study of its spectral properties on dilution, along with molecular modeling studies, allowed us to explain that this behavior involves the formation of a J-dimer, as well as how the sensing mechanism of Hg2+ proceeds

Gestión turística y eventos meteorológicos extremos en destinos litorales

El trabajo que se presenta a continuación aborda el impacto de fenómenos meteorológicos extremos (olas de frío, tormentas eléctricas, vientos fuertes, etcétera) en los destinos turísticos de la costa bonaerense para el período comprendido entre 2005-2015. Se realiza la identificación e inventario de los eventos meteorológicos de tipo extremo que tuvieron lugar en invierno, otoño y primavera. De esta manera se continua con el análisis realizado por Gil et al. (2015). Los resultados servirán para mejorar la gestión pública de los destinos turísticos en términos de la prevención y mitigación de eventos extremos.The work presented below addresses the impact of extreme weather (cold waves, thunderstorms, high winds, etc.) in tourist destinations in the Buenos Aires coast for the period 2005-2015. Identification and inventory of extreme weather events type that took place in winter, autumn and spring is performed. Thus we continue with the analysis by Gil et al. (2015). The results will serve to improve public management of tourist destinations, in terms of prevention and mitigation of extreme events

Seminal plasma AnnexinA2 protein is a relevant biomarker for stallions which require removal of seminal plasma for sperm survival upon refrigeration

Some stallions yield ejaculates that do not tolerate conservation by refrigeration prior to artificial insemination (AI), showing improvement after removal of most of the seminal plasma (SP) by centrifugation. In this study, the SP-proteome of 10 different stallions was defined through high-performance liquid chromatography with tandem mass spectrometry and bioinformatic analysis in relation to the ability of the ejaculates to maintain semen quality when cooled and stored at 5°C. Stallions were classified into three groups, depending on this ability: those maintaining good quality after direct extension in a commercial extender (good), stallions requiring removal of seminal plasma (RSP) to maintain seminal quality (good-RSP), and stallions, unable to maintain good semen quality even after RSP (poor). Pathway enrichment analysis of the proteins identified in whole equine SP using human orthologs was performed using g: profiler showing enriched Reactome and the Kyoto Encyclopedia of Genes and Genomes pathways related to hexose metabolism, vesicle mediated transport, post translational modification of proteins and immune response. Specific proteins overrepresented in stallions tolerating conservation by refrigeration included a peroxiredoxin-6 like protein, and transcobalamin-2, a primary vitamin B12-binding, and transport protein. Also, the protein involved in protein glycosylation, ST3 beta-galactoside alpha-2,3-sialyltransferase 1 was present in good stallions. These proteins were nearly absent in poor stallions. Particularly, annexinA2 appeared as to be the most powerful discriminant variable for identification of stallions needing RSP prior to refrigeration, with a P = 0.002 and a q value = 0.005. Overall this is the first detailed study of the equine SP-proteome, showing the potential value of specific proteins as discriminant bio-markers for clinical classification of stallions for AI

Surgical clavicle reconstruction after aneurysmal bone cyst resection in a child: A simple method

The clavicle is an infrequent location for primary tumors in general, and aneurysmal bone cyst (ABC) of the clavicle is particularly rare. The challenge of the functional and esthetic result in the treatment of these lesions in the pediatric population is high when considering the reconstruction of critical bone defects. In this article, we present the case of a seven -year -old boy with an ABC in the middle third of the clavicle, treated by resection and reconstruction with free autograft of the fibula stabilized by using an intramedullary titanium nail. We offer a description of the used technique, considerations about treatment options in children, and a follow-up of more than two -and -a -half years
