Influência governamental e estratégias institucionais na difus?o de inova??es em economias emergentes
Rodriguez, Carlos L.;Diniz, Eduardo H.;Ferrer, Florencia;
Revista de Administra??o de Empresas , 2007, DOI: 10.1590/S0034-75902007000100002
Abstract: in emerging economies, various public programs have been created to stimulate local ?rms to adopt innovations, with the ultimate goal of increasing rates of economic development. this paper provides a preliminary attempt to identify factors associated with institutional influences in the processes of innovation diffusion in those areas, and proposes some basic associations: between the governmental interventions and the phases of the process of innovation diffusion; between the actions of governments and the forces that stimulate the process; and between the public policies and the characteristics of the institutional environment generally found in emerging economies. the analysis integrates concepts from various ?elds in the social sciences to offer ?ve propositions, at different levels of analysis, describing various aspects of the potentially strong influence that national governments exert on the process through which innovations are diffused in the institutional environments of the areas known as emerging economies.

Revista de Biologia e Ciências da Terra , 2001,
Abstract: The Elanus leucurus is a rural species that happening from Argentina and Chile to North America that frequently benefits with the agricultural progresses. Studies about the reproductive behavior of the Elanus leucurus still has little knowledge in the scientific comunity and the present study aims at to know the habits and behavior of this species at this reproductive time. The work totaled about 460 hours of observations among the beginning of May untill October. The nestling behavior was observed by 60 hours in two diferrent nests in the area of Sete Lagoas and for 48 hours in the area of Divinópolis. The study of the biology and the alimentary ecology of the Elanus leucurus it's very important because little know on the strategies of conservation of the species and your biota, presenting an immense value for the control of diseases in the fields and neotropical savannahs.

Abstract: during the last few years, many models have been proposed to link microevolutionary processes to macroevolutionary patterns, defined by comparative data analysis. among these, brownian motion and ornstein-uhlenbeck (o-u) processes have been used to model, respectively, genetic drift or directional selection and stabilizing selection. these models produce different curves of pairwise variance between species against time since divergence, in such a way that different profiles appear in phylogenetic correlograms. we analyzed variation in body length among 19 species of south american owls, by means of phylogenetic correlograms constructed using moran's i coefficient in four distance classes. phylogeny among species was based on dna hybridization. the observed correlogram was then compared with 500 correlograms obtained by simulations of brownian motion and o-u over the same phylogeny, using discriminant analysis. the observed correlogram indicates a phylogenetic gradient up to 45 mya, when coefficients tend to stabilize, and it is similar to the correlograms produced by the o-u process. this is expected when we consider that body size of organisms is correlated with many ecological and life-history traits and subjected to many constraints that can be modeled by the o-u process, which has been used to describe evolution under stabilizing selection.
Single-pass measurement of the optical quality of the opossum eye
Oswaldo-Cruz, Eduardo;Pican?o-Diniz, Cristovam W.;Silveira, Luiz Carlos L.;
Psychology & Neuroscience , 2011, DOI: 10.3922/j.psns.2011.1.002
Abstract: this paper reports the results that are part of a series of experiments designed to evaluate aspects of the spatial resolution of the visual system of the opossum, didelphis marsupialis aurita. this nocturnal marsupial presents a well-developed eye, displaying features that reflect specialization for operation at low levels of luminosity. the species was shown to be slightly myopic, a feature that may prove to be valuable because of the increased depth of field. opossum visual acuity has been previously evaluated by means of determining the contrast sensitivity function (csf). the results indicate rather poor visual acuity compared with other nocturnal animals. in this paper, we describe the results obtained for the optical quality of the opossum's eye using a single-pass method. the results suggest that the opossum's optical system is capable of forming images that can be resolved when separated by an angular distance on the order of 6 minutes of arc.

Abstract: this descriptive, exploratory study was performed using a quantitative approach to address the profile of victims attended by the pernambuco prehospital air service. the events were evaluated from august 2007 to july 2008, corresponding to the first year of the hangar working in recife. in the studied period, 283 event forms were studied, with an average 23 events per month. regarding the flights, 66% were rescue flights with an answer-time of 11 minutes. as for the causes, 79% were external, mainly traffic accidents. most victims were male, with a median age range of 34 years. the rescue of severe cases should be fast and effective, thus this study analyzed the association between the severity of a victim and the answer-time.

Phylogeny among species was based on DNA hybridization. The observed correlogram was then compared with 500 correlograms obtained by simulations of Brownian motion and O-U over the same phylogeny, using discriminant analysis. The observed correlogram indicates a phylogenetic gradient up to 45 mya, when coefficients tend to stabilize, and it is similar to the correlograms produced by the O-U process. This is expected when we consider that body size of organisms is correlated with many ecological and life-history traits and subjected to many constraints that can be modeled by the O-U process, which has been used to describe evolution under stabilizing selection.

Abstract: This study aimed at knowing the psychometric parameters of the Antisocial and Delictive Behaviors Questionnaire (ADQ). Specifically, it tried to join evidences of its factor validity and reliability in the milieu of Paraíba-Brazil, as well as to know the adequacy of a briefed version of this measure. Two studies were accomplished. In Study 1, the participants were 480 students from high school, with a mean age of 16.2 years old (SD = 1.60), most of them were women (55.1%). In Study 2, 1,463 students of elementary school, high school, and university; with ages ranging from 10 to 36 years old (m = 16; SD = 4.41) participated in research, 59.9% were female. They answered the Antisocial and Delictive Behaviors Questionnaire and to demographic questions. Results supported the psychometric adequacy of this measure, which showed the theorized bi-factor structure. Moreover, the purpose of the ADQ briefed version revealed itself adequate, jointing evidences of factor validity and reliability similar to those of the original version. These findings were discussed based on literature and future researches are suggested as well.
