Aerial line transect survey to estimate abundance of marsh deer (Blastocerus dichotomus) (Illiger, 1815)

A população de cervo-do-pantanal (Blastocerus dichotomus) está drasticamente reduzida no Brasil. O nosso objetivo foi o de estimar a abundância do cervo-do-pantanal na bacia do Rio Paraná e discutir a metodologia aplicada. Os resultados darão suporte para uma análise do impacto do enchimento da represa de Porto Primavera sobre essa população. Sessenta e nove animais foram registrados através de sobrevôo utilizando-se a metodologia de transecção linear com amostragem das distâncias. Os dados não corrigidos resultaram em uma densidade estimada de 0,0035ind/ha e uma população de 636 indivíduos. A correção de g para os animais que não foram vistos apresentou uma densidade de 0,0049 ind/ha e uma abundância de 896 (CV=0,27) indivíduos. A metodologia foi aplicada com sucesso na estimativa de cervo-do-pantanal. Esse resultado é importante para avaliarmos a população do cervo-do-pantanal na área e para futuramente analisarmos o impacto do enchimento da represa.

Eugenio de Ochoa (1815-1872). El hombre de letras en la España de Isabel II

El nombre de Eugenio de Ochoa siempre aparece en los libros sobre la cultura española del siglo XIX, aunque pocas veces con un papel protagonista. Su lugar en la historia de la literatura se halla asociado a otros personajes o a empresas periodísticas de importancia que son recordadas por los nombres de esos otros: El Artista, Federico Madrazo, Pedro Madrazo, Juan Eugenio Hartzenbusch, Victor Hugo, Balzac… Y así Ochoa es siempre el co-creador de una revista, el cuñado de, el amigo de, el traductor de, el editor de… Esta posición secundaria ha restado atractivo al estudio de un hombre que desempeñó un papel fundamental en la conexión de la cultura española con Europa, tanto por ser el vehículo por el que llegaron a España muchos autores contemporáneos como por llevar a cabo el recorrido contrario, mostrando al continente el patrimonio cultural nacional. Sin embargo, esa faceta de intermediario, y no la de literato, contemplada desde una perspectiva más centrada en el contexto y menos en el canon literario tradicional, ofrece unas posibilidades de análisis extremadamente interesantes. Además, la gran pluralidad de sus actividades le convirtió en su tiempo en un observador privilegiado de la realidad cultural y política del país. Ahí se halla el objetivo que ha guiado la realización de este trabajo. Por medio del estudio de su figura se ha pretendido llevar a cabo un análisis de la cultura española del siglo XIX, partiendo de un enfoque sociológico de la misma y prestando más atención a las prácticas en el campo literario que al contenido de la creación. Esa es la razón que explica que, metodológicamente, el trabajo se apoye en dos pilares, cada uno de los cuales sirve de soporte a las dos partes centrales del mismo: la reflexión acerca del “hombre de letras” en el reinado de Isabel II y el papel desempeñado por el mediador cultural en el proceso de transferencia de conocimientos e imágenes nacionales en la Europa del siglo XIX. Al comienzo de cada uno de estos bloques se realiza una reflexión más detallada sobre ambas líneas de análisis que, por supuesto, no son las únicas y no agotan el tema...

Found lost and alive cities in virtual exhibitions. Arab World and Europe (1815-1918) a bridge to a cultural and architectural dialogue

Our proposal is to go around the thematic virtual exhibitions that we have prepares to Museums With No Frontiers - Cities and Urban Spaces 1815–1918, visibly embodied in alterations to the urban plans, views and architecture. – see: http://www.sharinghistory.org/

Comentario del libro de Arturo Taracena Arriola, Invención criolla, sueño ladino, pesadilla indígena. Los Altos de Guatemala: de la región al Estado, 1740-1850

IntroducciónDetrás del bello título y de las referencias explícitamente froidianas de este libro, el lector descubre en él un importante libro de historia regional. De golpe osamos a plantear una afirmación a manera de previsión, ejercicio que por cierto repugna tanto al historiador, pero que en este caso no deja de ser un tanto riesgoso. El trabajo de A. Taracena probablemente será por muchos años como una de esas referencias trascendentales para todos aquellos que decidan en el futuro plantear un estudio de historia regional.

Generalising unitary time evolution

In this third Quantum Interaction (QI) meeting it is time to examine our failures. One of the weakest elements of QI as a field, arises in its continuing lack of models displaying proper evolutionary dynamics. This paper presents an overview of the modern generalised approach to the derivation of time evolution equations in physics, showing how the notion of symmetry is essential to the extraction of operators in quantum theory. The form that symmetry might take in non-physical models is explored, with a number of viable avenues identified.

Augmenting web service discovery by cognitive semantics and abduction

We argue that web service discovery technology should help the user navigate a complex problem space by providing suggestions for services which they may not be able to formulate themselves as (s)he lacks the epistemic resources to do so. Free text documents in service environments provide an untapped source of information for augmenting the epistemic state of the user and hence their ability to search effectively for services. A quantitative approach to semantic knowledge representation is adopted in the form of semantic space models computed from these free text documents. Knowledge of the user’s agenda is promoted by associational inferences computed from the semantic space. The inferences are suggestive and aim to promote human abductive reasoning to guide the user from fuzzy search goals into a better understanding of the problem space surrounding the given agenda. Experimental results are discussed based on a complex and realistic planning activity.

The economics of credence goods: An experimental investigation of the role of verifiability, liability, competition and reputation in credence goods markets

Credence goods markets are characterized by asymmetric information between sellers and consumers that may give rise to inefficiencies, such as under- and overtreatment or market break-down. We study in a large experiment with 936 participants the determinants for efficiency in credence goods markets. While theory predicts that either liability or verifiability yields efficiency, we find that liability has a crucial, but verifiability only a minor effect. Allowing sellers to build up reputation has little influence, as predicted. Seller competition drives down prices and yields maximal trade, but does not lead to higher efficiency as long as liability is violated.

The impact of distributional preferences on (experimental) markets for expert services

Theory predicts that efficiency prevails on credence goods markets if customers are able to verify which quality they receive from an expert seller. In a series of experiments with endogenous prices we observe that verifiability fails to result in efficient provision behaviour and leads to very similar results as a setting without verifiability. Some sellers always provide appropriate treatment even if own money maximization calls for over- or undertreatment. Overall our endogenous-price-results suggests that both inequality aversion and a taste for efficiency play an important role for experts’ provision behaviour. We contrast the implications of those two motivations theoretically and discriminate between them empirically using a fixed-price design. We then classify experimental experts according to their provision behaviour.

Learning to win process-control games watching game-masters

The present paper focuses on some interesting classes of process-control games, where winning essentially means successfully controlling the process. A master for one of these games is an agent who plays a winning strategy. In this paper we investigate situations in which even a complete model (given by a program) of a particular game does not provide enough information to synthesize—even incrementally—a winning strategy. However, if in addition to getting a program, a machine may also watch masters play winning strategies, then the machine is able to incrementally learn a winning strategy for the given game. Studied are successful learning from arbitrary masters and from pedagogically useful selected masters. It is shown that selected masters are strictly more helpful for learning than are arbitrary masters. Both for learning from arbitrary masters and for learning from selected masters, though, there are cases where one can learn programs for winning strategies from masters but not if one is required to learn a program for the master's strategy itself. Both for learning from arbitrary masters and for learning from selected masters, one can learn strictly more by watching m+1 masters than one can learn by watching only m. Last, a simulation result is presented where the presence of a selected master reduces the complexity from infinitely many semantic mind changes to finitely many syntactic ones.
