Eczema atópico na crian?a e no adulto
Claro,Cristina;
Revista Portuguesa de Clínica Geral , 2011,
Abstract: a topic dermatitis is a chronic relapsing inflammatory skin condition, of increasing incidence. strict collaboration between the specialities that deal with this illness is essential. the epidemiology, aetiology and pathogenesis of atopic dermatitis will be briefly approached; the clinical features of the disease and some practical aspects of its treatment will be addressed.
La ciencia y el fin de los tiempos
Claro,Francisco;
Teología y vida , 2000, DOI: 10.4067/S0049-34492000000100007
Abstract: when science is asked to refer to the end of time the question of its real capability for predicting the future is brought about. here we question such capability and present the concept of a credibility horizon in scientific prediction, which makes explicit the existence of a limited scope to any statement about the future. in particular, the propositions of cosmology about the evolution of the material substrate that makes life posible, or about the end of time, must be read as statements of bounded validity and not as final truth.
La ciencia y el fin de los tiempos
Francisco Claro
Teología y vida , 2000,
Abstract: Cuando se pide a la ciencia que se refiera al fin del mundo se apela a su capacidad para predecir el futuro. Aquí cuestionamos dicha capacidad y presentamos el concepto de horizonte de credibilidad de la predicción científica, el que acota el alcance de toda afirmación acerca del futuro. En particular, las proposiciones de la cosmología acerca del devenir del entorno material que sustenta la vida humana o del fin del mundo, deben leerse como afirmaciones de alcance limitado, y no como verdades finales. When science is asked to refer to the end of time the question of its real capability for predicting the future is brought about. Here we question such capability and present the concept of a credibility horizon in scientific prediction, which makes explicit the existence of a limited scope to any statement about the future. In particular, the propositions of cosmology about the evolution of the material substrate that makes life posible, or about the end of time, must be read as statements of bounded validity and not as final truth.
Genetically Modified Organisms
Claro Llaguno
Science Diliman , 2001,
Abstract: Recent reports have brought to public attention concerns about Bt corn and genetically modified organisms (GMO) in general. The timing, it seems, is most appropriate considering two related developments early this year: the final approval of the Cartagena Protocol on Biosafety in Montreal on January 29, 2001, and the OECD Edinburgh Conference on GM food safety last February 28- March 1, 2001. The protocol makes clear that GMOs include all living modified organisms (LMO) defined as "any living organism that possesses a novel combination of genetic material obtained through the use of modern biotechnology". This includes seeds, live fish, and other organisms intentionally obtained for release to the environment. It would seem that the common understanding about GMOs as referring to farm-to-table products is perforce expanded to embrace genetically modified farm animals and aquatic resources. Being a trade agreement, the Montreal accord primarily deals with the safety issues related to the transboundary movement of LMOs around the globe. The OECD conference on the other hand, called for an international body "to address all sides of the GM debate" in response to the public outcry, particularly in Western Europe, regarding the risks the new products pose to human health and the environment. Some points of contention, which remain unresolved, include issues such as whether countries should be allowed to develop their own GM food based on their needs, and whether a global moratorium on GMOs and mandatory labeling should be enforced worldwide.
Graphene-like massless Dirac fermions in Harper systems
F. Claro
Physics , 2007,
Abstract: It is shown that systems described by Harper's equation exhibit a Dirac point at the center of the spectrum whenever the field parameter is a fraction of even denominator. The Dirac point is formed by the touching of two subbands, and the physics around such point is characterized by the relative field only, as if the latter were null at the reference value. Such behavior is consistent with the nesting property conjectured by Hofstadter, and its experimental verification would give support to such hypothesis as well as the Peierls-Onsager ansatz used to arrive at Harper's equation when crystalline electrons move in a uniform external magnetic field
Managing trust relationships: calculative, affective, belief and performance
Claro, Danny Pimentel;Claro, Priscila B. Oliveira;
BAR. Brazilian Administration Review , 2008, DOI: 10.1590/S1807-76922008000400004
Abstract: there is an ongoing concern among managers and scholars: how can firms develop trust and achieve performance? our paper aims to review the emerging perspective of trust and propose mechanisms to build trust in channel relationships. in the literature, we identified six mechanisms: calculative, affective, belief, embeddedness, continuity and capability. a central hypothesis focuses on the direct impact of these mechanisms on firm performance. we conducted a survey (n=132) in the brazilian distribution market of agrochemical products. ols regression estimation was employed to test the hypothesis. results show the impact of the mechanisms of calculative, affective, belief on performance. the findings highlight that, even though environment leads to suspicion and doubts, managers seek trust relationships and try to develop them using a combination of few mechanisms to overcome difficulties and perform well.
Managing Trust Relationships: Calculative, Affective, Belief and Performance

Multitrophic relationships, conditional mutualisms, and the study of interaction biodiversity in tropical savannas
Del-Claro, Kleber;
Neotropical Entomology , 2004, DOI: 10.1590/S1519-566X2004000600002
Abstract: biodiversity as a focus for conservation efforts has received increased attention since the second half of the last century. until recently a more landscape-level view of biodiversity has prevailed. this essay proposes to discuss natural diversity in ways that embrace the extreme richness inherent in plant animal interactions, including not only trophic relationships, but also aspects of life history, biology, and behavior of related species. the ant-plant-herbivore systems in cerrado vegetation are pointed out as good model for gaining a better understanding of "interaction biodiversity".
A CROSS-COUNTRY ESTIMATION OF THE ELASTICITY OF SUBSTITUTION BETWEEN LABOR AND CAPITAL IN MANUFACTURING INDUSTRIES
CLARO,SEBASTIáN;
Cuadernos de economía , 2003, DOI: 10.4067/S0717-68212003012000003
Abstract: this paper presents a simple methodology to estimate the elasticity of substitution between labor and capital for firms operating in perfectly competitive factor markets with constant-elasticity-of-substitution technologies. it is applied to a cross-country sample of 28 3-digit isic manufacturing industries. the econometric procedure relies on measures of sectorial capital stock, that are estimated for 34 countries in 1990. unlike previous studies, the estimates are compatible with international technology differences. the results reveal that in most industries the elasticity of substitution is close to one. however, the null hypothesis of cobb-douglas production functions is in general rejected
Los servicios de suministros de los establecimientos sanitarios: la medición de la performance
Dacosta Claro,Iván;
Revista Espa?ola de Salud Pública , 2001, DOI: 10.1590/S1135-57272001000400006
Abstract: performance measurement, in their different meanings -either balance scorecard or outputs measurement- have become an essential tool in today?s organizations (world-class organizations) to improve service quality and reduce costs. this paper presents a performance measurement system for the hospital supply chain. the system is organized in different levels and groups of indicators in order to show a hierarchical, coherent and integrated vision of the processes. thus, supply services performance is measured according to (1) financial aspects, (2) customers satisfaction aspects and (3) internal aspects of the processes performed. since the informational needs of the managers vary within the administrative structure, the performance measurement system is defined in three hierarchical levels. firstly, the whole supply chain, with the different interrelation of activities. secondly, the three main processes of the chain -physical management of products, purchasing and negotiation processes and the local storage units. and finally, the performance measurement of each activity involved. the system and the indicators have been evaluated with the participation of 17 health services of quebec (canada), however, and due to the similarities of the operation, could be equally implemented in spanish hospitals.
