New insights in Bayesian Survival Analysis in Ecology
2020
La fauna silvestre está asediada. Y ésta no es solo una frase impactante con la que empezar una tesis, tristemente, es una realidad. En el último siglo, muchas especies han disminuido drásticamente, mientras que otras afrontan su extinción debido, principalmente, a los rápidos cambios (y a gran escala) ocurridos tanto en hábitats como en ecosistemas. El cambio climático, las especies invasoras, la caza ilegal y la sobrepesca son sólo algunas de las principales amenazas que afectan a las poblaciones de animales silvestres en la actualidad. Para abordar este problema, se requiere de un compromiso a todos los niveles, desde las comunidades locales hasta los gobiernos, pasando por los expertos,…
EXPRESSIONS OF DISCOMFORT IN ADOLESCENTS. CLINICAL REFLECTIONS RESULTING FROM AN EXPLORATORY STUDY OF A GROUP OF STUDENTS
2006
Obiettivo. Considerati la diffusione e l’incremento dei comportamenti aggressivi e violenti, specie quelli che trovano come radicale comune la mancanza di un’effettiva motivazione e l’efferatezza, la nostra ricerca si è posta l’obiettivo di rintracciare gli indicatori e i segni predittivi di tali comportamenti. La letteratura, inoltre, dimostra che gli indicatori e i segni predittivi di maggiore affidabilità sono quelli legati alle invarianti strutturali (per esempio le strategie difensive, la capacità di controllo degli impulsi). Metodi. È stato realizzato, con un piano di ricerca trasversale, uno studio clinico di confronto reclutando un gruppo di adolescenti (26 soggetti di sesso maschil…
Depth of alveolar bone dehiscences in relation to gingival recessions.
1984
Dehiscence depths were measured in vivo during surgical treatment of 113 teeth with gingival recession in 27 subjects. The average dehiscence depth determined was 5.43 mm with an average recession depth of 2.67 mm. Statistical evidence of a correlation between recession depth and dehiscence depth (average distance between lowest point of recession and dehiscence = 2.8 mm) leaves 16 affected teeth (n = 113) with a distance of 4 mm or more (up to a maximum of 7.5 mm) between the gingival margin and the alveolar crest (facial) unaccounted for. The significance of these deviations from mean values in the etiology and prognosis of recessions is discussed.
Finite-size scaling in a microcanonical ensemble
1988
The finite-size scaling technique is extended to a microcanonical ensemble. As an application, equilibrium magnetic properties of anL×L square lattice Ising model are computed using the microcanonical ensemble simulation technique of Creutz, and the results are analyzed using the microcanonical ensemble finite-size scaling. The computations were done on the multitransputer system of the Condensed Matter Theory Group at the University of Mainz.
Classical and Quantum Two-Dimensional Fluids in the Gibbs Ensemble
1994
We study the properties of model fluids in two spatial dimensions with Gibbs ensemble Monte Carlo (GEMC) techniques. In particular in the first part of the paper we study the entropy driven phase separation in case of a nonadditive symmetric hard disc fluid and locate by a combination of GEMC with finite size scaling techniques the critical line of nonadditivities as a function of the system density, which separates the mixing/demixing regions, we compare with a simple approximation. In the second part we successfully combine path integral Monte Carlo (PIMC) and GEMC techniques in order to locate the gas-liquid coexistence densities for a fluid with classical degrees of freedom and internal…
Relational priming is to analogy-making as one-ball juggling is to seven-ball juggling
2008
Relational priming is argued to be a deeply inadequate model of analogy-making because of its intrinsic inability to do analogies where the base and target domains share no common attributes and the mapped relations are different. The authors rely on carefully handcrafted representations to allow their model to make a complex analogy, seemingly unaware of the debate on this issue 15 years ago. Finally, they incorrectly assume the existence of fixed, context-independent relations between objects. Although relational priming may indeed play some role in analogy-making, it is an enormous – and unjustified – stretch to say that it is “centrally implicated in analogical reasoning” (sect. 2, para…
“The Limits” of Economic Growth in Romania
2014
Abstract A sustainable economic growth of GDP of 3-4% annually in Romania for the reduction of gaps in development was considered impossible by most institutions of various skill and opinion leaders, as well as of international financial bodies. The reasons cited were delayed public reforms, low growth potential as a result of the crisis, the overview status of the states in the Eurozone dependent on inside community trade and also the prospects for a lasting economic stagnation, the balance sheet effect, as a result of over indebtedness of firms and individuals that substantially reduced inclination towards investment and consumption. Contradicting these forecasts, in 2013, Romania's econo…
Third Sector, Social Enterprises and Local Authorities in a EU Candidate Country. The Case of Albania
2013
The paper is based on evidence offered by survey data collected through a structured questionnaire in a long range survey launched in July 2012 by the Steering Group of ASE Forum. The aim of the study was to reveal the trend, status, profile, features and the role of potentials enterprises in Albania in supporting welfare and wellbeing in synergy with the local authorities.After an appropriate methodological introduction, the paper reports main statistical evidence concerning the Third sector in Albania and the direct survey outcomes about the features and the activity of the organizations interviewed.Conclusions will be driven by data analysis and will be focused on the needs, limits and o…
Modeling the Dynamics of a Financial Index after a Crash
2004
Supply and demand are perhaps the most fundamental concepts in economics. In a financial market they reflects the orders of the agents to buy or sell a given asset. In turn the fluctuations of supply and demand influence the dynamics of the price of an asset, as, for example, a stock or a financial index. Therefore the dynamics of the price of an asset is affected by the actions and of the beliefs of the agents. It is known that the dynamics of the price of an asset is far from simple, Several stylized facts has been empirically discovered such as, for example, the fat tails in the return distribution and the clustered volatility. These stylized facts has been detected by considering long t…
