TENDENCIAS DE LIDERAZGO EN EL DOCENTE VENEZOLANO DE LA I ETAPA DE EDUCACIóN BáSICA: ESTUDIO DE CASOS
Carrera,Beatriz;
Investigación y Postgrado , 2002,
Abstract: this research aimed at determining the most striking leadership characteristics of teachers in the first stage of basic education. it employed the bass and avolio (1991 b) instrument, which makes it possible to distinguish among three constructs: the transformational leader, the transactional leader, and the laisser faire leader. the instrument is an adaptation consisting of 87 items in two formats: one for self-evaluation, to be filled out by the teacher, and another to be filled by the student who will appraise his/her teacher. the present study is oriented by its objectives toward a case study method. a study was carried out among the "a" and "b" section third grade teachers at maría inmaculada school, and their students. this institution actively participates in the pedagogical projects stipulated in the national basic curriculum (education ministry, 1998). the highest frequency of behaviors was found to be related to the presence of transformational leader-type teachers, and teachers of this kind were found to inspire trust and respect, according to the children's opinion, and to induce commitment in the teachers' judgment. both of these features are consistent with what is to be expected of an effective transformational leader.

Todo sobre el neobarroco

Cuadernos LIRICO : Revista de la Red Interuniversitaria de Estudios sobre las Literaturas Rioplatenses Contemporáneas en Francia , 2007,
Abstract: Lo que hemos escuchado y atendido hasta aquí, hoy, ayer, sobre todo en la propuesta poética esbozada por Sergio Raimondi en su ensayo sobre Aldo Oliva, demuestra que las singularidades, su pasión, anulan subrepticiamente las nominaciones.Anoche en la televisión una orquesta sinfónica y un coro numeroso. Súbitamente, me hubiera gustado ser uno de esos intérpretes solitarios para sí, a pesar de la armonía, anónimos, a pesar del brillo sonoro… un violín, un triángulo… apenas… tres grillos… como ...
Peter Carravetta, Del postmoderno.
Alessandro Carrera
European Journal of American Studies , 2010, DOI: 10.4000/ejas.8516
Abstract: Peter Carravetta, professor of “Italian and Italian American Studies” at SUNY Stony Brook, with an Italian and American education, has put together in his massive Del postmoderno possibly the most complete critical review so far of American academic production from the 1970s to the present. “Postmodern” is the key word of the cultural turn that took place between the 1950s and the 1970s only to meet its death, in Carravetta’s opinion, on September 11, 2001, when the shortlived illusion that h...
Gerenciamento de Impress es, Música e Sites de Redes Sociais: o self a partir do compartilhamento de letras e vídeos
CARRERA, Fernanda
Contemporanea : Revista de Comunica??o e Cultura , 2012,
Abstract: This article discusses how to share lyrics and music videos on social networking sites - specifically Facebook - is used in the process of impression management. From the establishment of analytical categories, try to understand how music can be a strategic resource for the maintenance of the social face and the social representation of self in the digital environment.
Physics with Single Photons plus Missing Energy Final States at D0
Edgar Carrera
Physics , 2009,
Abstract: Final state signatures of a single photon and missing transverse energy offer unique and powerful advantages in the search for new physics. This document presents the first observation of the Zgamma to nunu_bargamma process at the Tevatron Collider at 5.1 standard deviations significance, as well as some of the strongest limits on anomalous trilinear ZZgamma and Zgammagamma couplings to date. Additionally, we present the latest D0 results on a search for direct production of Kaluza Klein gravitons in association with single photons.
Searching for the elusive graviton
Edgar Carrera
Physics , 2008,
Abstract: We present a search for large extra dimensions in the single photon plus missing transverse energy channel (Kaluza-Klein graviton production) performed using 2.7 fb-1 of data collected by the D0 experiment at the Fermilab Tevatron collider. At 95% C.L., we set limits on the fundamental Planck scale M_{D} from 970 GeV to 816 GeV for two to eight extra dimensions.
Analysis of the CN and CH molecular band strengths in stars of the open cluster NGC 6791
R. Carrera
Physics , 2012, DOI: 10.1088/0004-637X/758/2/110
Abstract: Low resolution SDSS/SEGUE spectra have been used to study the behavior of the strengths of the CN and CH molecular bands in stars at different evolutionary stages of the open cluster NGC 6791. We find a significant spread in the strengths of the CN bands, more than twice that expected from the uncertainties, although the bimodalities observed in globular clusters are not clearly observed here. This behavior, is observed not only among red clump objects but also in unevolved stars such as those in the main sequence and lower red giant branch. In contrast, not all the stars studied show significant scatter in their CH strengths.
Radial velocities and metallicities from infrared Ca II triplet spectroscopy of open clusters: Berkeley 26, Berkeley 70, NGC 1798, and NGC 2266
R. Carrera
Physics , 2012, DOI: 10.1051/0004-6361/201219625
Abstract: Context: Open clusters are ideal test particles for studying the formation and evolution of the Galactic disk. However, the number of clusters with information about their radial velocities and chemical compositions remains largely insufficient. Aims: We attempt to increase the number of open clusters with determinations of radial velocities and metallicities from spectroscopy. Methods: We acquired medium-resolution spectra (R~8000) in the region of the infrared Ca II triplet lines (~8500\AA) for several stars in four open clusters with the long-slit spectrograph IDS at the 2.5m Isaac Newton Telescope, Roque de los Muchachos Observatory, Spain. Radial velocities were obtained by cross-correlating the observed spectra with those of two template stars. We used the relationships available in the literature between the strength of infrared Ca II lines and metallicities to derive the metal content of each cluster. Results: We provide the first spectroscopic determinations of radial velocities and metallicities for the open clusters Berkeley 26, Berkeley 70, NGC 1798, and NGC 2266. We obtain =68$\pm$12, -15$\pm$7, 2$\pm$10, and -16$\pm$15 km s$^{-1}$ for Berkeley 26, Berkeley 70, NGC 1798, and NGC 2266, respectively. For Berkeley 26 we derive a metallicity of [Fe/H]=-0.35$\pm$0.17 dex. Berkeley 70 has a solar metallicity of [Fe/H]=-0.01$\pm$0.14 dex, while NGC 1798 has a slightly lower metal content of [Fe/H]=-0.12$\pm$0.07 dex. Finally, we derive a metallicity of [Fe/H]=-0.38$\pm$0.06 dex for NGC 2266.
Pulperos rurales: entre la vida privada y la pública
Carrera,Julián;
Mundo agrario , 2004,
Abstract: this article studies the private life of rural pulpero in the countryside of buenos aires and the activities developed when he is out of his store. through the analysis of testaments and inventorys of rural pulperos of buenos aires of late xviii century and early xix century the study attempt to penetrate in the privacy and alternatives activities. the work proves the existence of a space protected from the public intrusion. if is true that the frontier between private and public spaces often is widespread, the privacy has been conquered more an less for many rural pulperos. in this way the article place in doubt the image of general rusticity which involved rural life and place the pulperos inside the meddle classis of countryside population.
