Assortative mating by size without a size-based preference: the female-sooner norm as a mate-guarding criterion.
2013
7 pages; International audience; The study of size-assortative mating, or homogamy, is of great importance in speciation and sexual selection. However, the proximate mechanisms that lead to such patterns are poorly understood. Homogamy is often thought to come from a directional preference for larger mates. However, many constraints affect mating preferences and understanding the causes of size assortment requires a precise evaluation of the pair formation mechanism. Mate-guarding crustaceans are a model group for the study of homogamy. Males guard females until moult and reproduction. They are also unable to hold a female during their own moult and tend to pair with females closer to moult…
The language of recovery
2020
Abstract The present study attempts to make a comparative analysis of two Spanish and American political speeches, which belong to two different debate traditions, in terms of the metaphors used. For that purpose, we analyze the Economy sections of the 2015 State of the Union Address in the US and in the 2015 State of the Nation Debate in Spain. The present study aims at answering the following research questions: What metaphors do President Obama and Prime Minister Rajoy use in the American and Spanish political speeches to convince their audiences of America’s and Spain’s economic victory? What are the similarities and differences between the representations depicted by metaphor use in th…
The Relationship Between Safety Attitudes and Occupational Accidents
2011
This research provides empirical evidence on the relationships between employee attitudes to safety issues and accident indicators in a Spanish context. The research attempts to review to what degree those attitudes reflect a collective, or shared, climate for safety within a number of organizations. Data were gathered from workers in a number of industries in Valencia (Spain) by questionnaire. A total of 1,234 valid questionnaires were completed and formed the basis for subsequent analysis. Analysis of the attitude dimensions found a similar structure to that found in previous research in other countries, as well as identifying those dimensions shared within groups, more likely to represe…
Rol del perito psicólogo en el ámbito judicial
2008
In the field of Justice, a psychologist acts as a Psychology Expert and assists the Judge by supplying psychological techniques within a frame which is different from the clinic one. In this environment, the role of the psychologist is to diagnose and evaluate the psychological harm a person could have suffered as a consequence of a harmful event for example an accident, so that the victim may receive the corresponding money compensation. A psychology expert also acts in case of minor guardianship, divorce, mala praxis etc. Our proposal is to continue investigating in order to re-define the concept of psychological harm and to design new tables for determining the harm percentage.
Kasiski's Test: Couldn't the Repetitions be by Accident?
2006
Abstract In searching for repetitions in a periodic polyalphabetic ciphertext, we usually find several true (causal) repetitions that give information about the period. But we also find some accidental repetitions at distances unrelated to the period which may mislead the cryptanalyst. A simple formula shows that these accidents are rather unlikely.
How to formulate an accident prediction model for urban intersections.
2009
Several safety prediction models and methods have been developed to eliminate the relationship between the expected accident frequency and various urban intersection geometry and operational attributes. It is generally accepted that accident rates tend to be higher at intersections than on through sections of a road. This is particularly frequent in urban area where roads are characterized by intersections in close succession; moreover, the safe and effective operations of the urban road system can be significantly affected by safety conditions at intersections. In this paper models and methods designed to understand and to predict the accident process at urban intersections are reviewed. I…
Warren Buffett versus Zvi Bodie: Should You Buy Or Sell Put Options?
2021
Academics and investment professionals often disagree when it comes to investment advice. Legendary investor Warren Buffett is a proponent of time diversification and firmly believes that stocks are less risky in the long run. Therefore, he often sells long-term put options instead of buying them for portfolio protection. By contrast, the famous finance professor Zvi Bodie argues that time diversification is a fallacy and, therefore, his advice to fund managers is to buy long-term portfolio insurance. In this article, we consider the optimal portfolio choice problem for a loss-averse investor. First, we demonstrate that our loss-averse investor subscribes to the principle of time diversific…
Anti-Speciesist Rhetoric
2017
The various laws protecting animals that were established in Nazi Germany (but for the most part were never put into effect) had, among others, the aim of marking the taxonomic and ontological distance between pure animals and impure sub-humans (Jews, homosexuals, the Roma). The attention to and respect for the alpha predator and noble animals was a vertiginous ignoratio elenchi of the concentration camps. With analogous fallacy, today’s anti-human and anti-speciesist eco-fascism, which regularly makes use of the reductio ad Hitlerum (“meat-eaters = Nazis”), avails itself in an irrational and populist way of the rudimentary argumentum ad personam typical of xenophobic and racist propaganda.…
Convergence analysis for hierarchical longitudinal data
2018
Abstract Convergence analysis is typically envisaged either from a macro or a micro perspective. However, empirical tests tend to ignore that the two levels are often “nested” in a hierarchy. Building on hierarchical growth curve modelling, we propose an approach to convergence analysis that allows contemporaneous inference on macro and micro-convergence. Compared to the classic linear convergence analysis, the suggested methodology provides a more flexible alternative to model heterogeneity and validate the results for possible Galton's fallacy. We illustrate the approach in two empirical examples, one considering convergence across European regions and countries and the other across Itali…
Falacias sobre el valor p compartidas por profesores y estudiantes universitarios
2017
Resumen La “Práctica Basada en la Evidencia” exige que los profesionales valoren de forma crítica los resultados de las investigaciones psicológicas. Sin embargo, las interpretaciones incorrectas de los valores p de probabilidad son abundantes y repetitivas. Estas interpretaciones incorrectas afectan a las decisiones profesionales y ponen en riesgo la calidad de las intervenciones y la acumulación de un conocimiento científico válido. Identificar el tipo de falacia que subyace a las decisiones estadísticas es fundamental para abordar y planificar estrategias de educación estadística dirigidas a intervenir sobre las interpretaciones incorrectas. En consecuencia, el objetivo de este estudio e…
