Organizational resources and intrapreneurial activities: a cross-country study

The importance of entrepreneurship for social and economic growth is generally accepted. In addition, intrapreneurship or corporate entrepreneurship is recognized as one of the key elements for organizational development. In this context, corporate culture and, specifically, entrepreneurial competences are considered to be catalysts for intrapreneurship. The main purpose of this paper is to analyse the influence of resources and capabilities on the probability of becoming an intrapreneur. Using data obtained from the Global Entrepreneurship Monitor (GEM) for 39 countries, and a logistic model, the study shows that entrepreneurial resources and capabilities, such as previous entrepreneurial experience, entrepreneurial competences and the ability to detect business opportunities, influence intrapreneurial behaviour. The contributions of this research are both conceptual (advancing corporate entrepreneurship theory) and practical (relating to the design of policies to foster intrapreneurial activities).

Association of NTRK3 and its interaction with NGF suggest an altered cross-regulation of the neurotrophin signaling pathway in eating disorders

Eating disorders (EDs) are complex psychiatric diseases that include anorexia nervosa and bulimia nervosa, and have higher than 50% heritability. Previous studies have found association of BDNF and NTRK2 to ED, while animal models suggest that other neurotrophin genes might also be involved in eating behavior. We have performed a family-based association study with 151 TagSNPs covering 10 neurotrophin signaling genes: NGFB, BDNF, NTRK1, NGFR/p75, NTF4/5, NTRK2, NTF3, NTRK3, CNTF and CNTFR in 371 ED trios of Spanish, French and German origin. Besides several nominal associations, we found a strong significant association after correcting for multiple testing (P = 1.04 × 10−4) between ED and rs7180942, located in the NTRK3 gene, which followed an overdominant model of inheritance. Interestingly, HapMap unrelated individuals carrying the rs7180942 risk genotypes for ED showed higher levels of expression of NTRK3 in lymphoblastoid cell lines. Furthermore, higher expression of the orthologous murine Ntrk3 gene was also detected in the hypothalamus of the anx/anx mouse model of anorexia. Finally, variants in NGFB gene appear to modify the risk conferred by the NTRK3 rs7180942 risk genotypes (P = 4.0 × 10−5) showing a synergistic epistatic interaction. The reported data, in addition to the previous reported findings for BDNF and NTRK2, point neurotrophin signaling genes as key regulators of eating behavior and their altered cross-regulation as susceptibility factors for EDs.

Cross recurrence quantification for cover song identification

There is growing evidence that nonlinear time series analysis techniques can be used to successfully characterize, classify, or process signals derived from realworld dynamics even though these are not necessarily deterministic and stationary. In the present study we proceed in this direction by addressing an important problem our modern society is facing, the automatic classification of digital information. In particular, we address the automatic identification of cover songs, i.e. alternative renditions of a previously recorded musical piece. For this purpose we here propose a recurrence quantification analysis measure that allows tracking potentially curved and disrupted traces in cross recurrence plots. We apply this measure to cross recurrence plots constructed from the state space representation of musical descriptor time series extracted from the raw audio signal. We show that our method identifies cover songs with a higher accuracy as compared to previously published techniques. Beyond the particular application proposed here, we discuss how our approach can be useful for the characterization of a variety of signals from different scientific disciplines. We study coupled Rössler dynamics with stochastically modulated mean frequencies as one concrete example to illustrate this point.

Plaza en red. Características del seguimiento informativo de la@acampadaBCN por parte de los/las jóvenes participantes en Plaza Cataluña.

Los indignados salieron a las calles y ocuparon las plazas físicamente. También la plaza virtual a través de las redes sociales, blogs y otras herramientas en red. Los rasgos de la comunicación digital se han hecho presentes en asambleas y acampadas a través de sus máximos representantes: los jóvenes. Una juventud que ha sabido utilizar la tecnología para hacerse presente en la sociedad y reivindicar (se). Los participantes en la @acampadaBCN han sabido encontrar sus propias formas de participación y de movilización social a través de las redes sociales y las nuevas tecnologías de la información y la comunicación. En este informe se presentan los resultados sobre las características del seguimiento informativo de la @acampadaBCN por parte de los/las jóvenes participantes en Plaza Cataluña. Se describe el perfil de los encuestados, el primer y posteriores canales de seguimiento de información sobre la @acampadaBCN, los canales de información utilizados por los indignados para seguir el desalojo del 27 de mayo de 2011, el tipo de interacción con las distintas herramientas digitales de la acampada y el cambio de referente informativo que ha provocado la perdida de credibilidad de los medios convencionales frente a la red. Sus referentes políticos, mediáticos y sociales ya no están en los partidos políticos, en la televisión, en la prensa o en la radio; ahora se informan a través de la red y, a través de ella y de sus perfiles en las redes sociales, difunden las informaciones que protagonizan, les interesan o obtienen su credibilidad. Los resultados de este informe surgen tras una inmersión participante en el movimiento de indignados. Asimismo, se realizaron 15 entrevistas a diferentes perfiles presentes en la #acampadaBCN y 339 encuestas realizadas a jóvenes que visitaron la plaza.

Metro display: sistema de visualización de información en una red de transporte público

El siguiente proyecto está centrado en el desarrollo de un ambient display para noticias situado en los vagones del Metro de Barcelona y cuya finalidad es establecer una nueva manera de hacer llegar información a la gente que se encuentra en espacios públicos, sin que se requiera de su total atención para ello. El proyecto cubre la concepción de la idea, la extracción de los requerimientos, así como la implementación y evaluación de un prototipo funcional.Los principales retos de este proyecto son comprender las características del entorno de despliegue (en este caso la red de metro), identificar las necesidades e intereses de la gente, y entonces desarrollar un diseño adecuado capaz de integrarse correctamente en ese entorno.Durante este proyecto se ha llevado a cabo un análisis detallado del entorno del Metro de Barcelona y las personas presentes en él, y consecuentemente se han definido los requerimientos del ambient display. El diseño del display se ha desarrollado en base a estos requerimientos y, finalmente, se ha evaluado la integración del display en su entorno. Todo este proceso es explicado en el presente documento.

The HP-filter in cross-country comparisons

Many empirical studies of business cycles have followed the practise ofapplying the Hodrick-Prescott filter for cross-country comparisons. Thestandard procedure is to set the weight \lambda, which determines the'smoothness' of the trend equal to 1600. We show that if this value isused for against common wisdom about business cycles. As an example, weshow that the long recession occurred inSpain between 1975 and 1985 goesunnotoced by the HP filter. We propose a method for adjusting \lambda byreinterpreting the HP-filter as the solution to a constrained minimizationproblem. We argue that the common practice of fixing \lambda across countriesamounts to chankging the constraints on trend variability across countries.Our proposed method is easy to apply, retains all the virtues of thestandard HP-filter and when applied to Spanish data the results are inthe line with economic historian's view. Applying the method to a numberof OECD countries we find that, with the exception of Spain, Italy andJapan, the standard choice of \lambda=1600 is sensible.

Red tape and delayed entry

Does cutting red tape foster entrepreneurship in industries with the potential to expand? We address this question by combining the time needed to comply with government entry procedures in 45 countries with industry-level data on employment growth and growth in the number of establishments during the 1980s. Our main empirical finding is that countries where it takes less time to register new businesses have seen more entry in industries that experienced expansionary global demand and technology shifts. Our estimates take into account that proxying global industry shifts using data from only one country or group of countries with similar entry regulations will in general yield biased results.

The equity premium and the risk free rate: A cross country, cross maturity examination

This paper examines the relationship between the equity premium and the risk free rate at three different maturities using post 1973 data fora panel of 7 OECD countries. We show the existence of subsample instabilities,of some cross country differences and of inconsistencies with the expectations theory of the term structure. We perform simulations using a standard consumptionbased CAPM model and demonstrate that the basic features of Mehra and Prescott's(1985) puzzle remain, regardless of the time period, the investment maturity and the country considered. Modifications of the basic setup are also considered.

Estimating the probability of leaving unemployment using uncompleted spells from repeated cross-section data

We propose a new econometric estimation method for analyzing the probabilityof leaving unemployment using uncompleted spells from repeated cross-sectiondata, which can be especially useful when panel data are not available. Theproposed method-of-moments-based estimator has two important features:(1) it estimates the exit probability at the individual level and(2) it does not rely on the stationarity assumption of the inflowcomposition. We illustrate and gauge the performance of the proposedestimator using the Spanish Labor Force Survey data, and analyze the changesin distribution of unemployment between the 1980s and 1990s during a periodof labor market reform. We find that the relative probability of leavingunemployment of the short-term unemployed versus the long-term unemployedbecomes significantly higher in the 1990s.
