Upper lower Eocene calcareous nannoplankton from the Las Pocitas core (Tepetate formation), Baja California Sur, Mexico
García-Cordero, Erandi;Carreo, Ana Luisa;
Revista mexicana de ciencias geológicas , 2009,
Abstract: sixty species of calcareous nannoplankton from the tepetate formation were recovered from a drill hole near las pocitas, baja california sur. in spite of its low abundance and erratic distribution throughout the sedimentary column, the great amount of reworked species, as well as the absence of traditional index fossils representing the standard tropical biozonation, the co-occurrence of reticulofenestra dyctioda, rhabdosphaera crebra, r. pinguis, micrantholithus flos, pontosphaera pectinata and lanternithus minutus situates the studied stratigraphic column at the discoasteroides kuepperi cp12a subzone of okada and bukry, dated between 49.5 and 49 ma at the top of the upper lower eocene. the population structure as well as the lithological features of the sedimentary package, suggest a temperate open-sea deposit, which confirms interpretations based on other marine fossils at arroyo datilar, el conejo, salada, colorado y las pocitas, where rocks of the lower middle eocene tepetate formation crop out.
Posgrados sobre desarrollo en América Latina: origen y evolución
Carreo,Claudia Inés;
Educación y Educadores , 2011,
Abstract: the focus of this study is on postgraduate education in development in the latin american context. the objective is to show how postgraduate courses of this type emerge in latin america and their contents, as well as what they teach and how. a qualitative approach was used to develop the study, particularly a content analysis of written documents coupled with in-depth interviews of experts and professors. the principal findings show a strong emphasis on the teaching of development understood as economic growth, with special emphasis on the models necessary to encourage it. however, there also is evidence that the human development perspective has begun to gain importance. it is a view in which economic development is an aspect, but not the only one. generally speaking, postgraduate courses in development place a priority on local-scale studies. however, it is essential to go beyond these analyses to other scales and in the direction of more multidimensional studies.
Más allá de la tarea: pistas para una redefinición del concepto de Motivación Escolar
Valenzuela Carreo, Jorge;
Educa??o e Pesquisa , 2007, DOI: 10.1590/S1517-97022007000300002
Abstract: the work investigates the various approaches to the issue of motivation, and in this context observes and questions the idea of school motivation that emphasizes the role of tasks, turning the completion of the latter into the motivation to carry out the activities required by the school, instead of stressing the motivation to learn. the author indicates some aspects or variables that should be considered when building up school motivation. these pointers are specifically related to the incorporation inside this construct of the reasons pupils have to attend school, and which give meaning to their school learning, thereby complementing the variables associated to the tasks. thus, without forgetting that the students must put effort into the completion of the tasks designed for their learning, we should recall the essentials of school motivation, namely, that which drives, conducts and sustains the students' efforts, and triggers cognitive resources to learn. a learning which, as it is consensual among educators, must not limit itself to the mere acquisition of information, but should be processed. the knowledge constructed (pozo, 2003) is thus made meaningful (ausubel, 1978) and deep (beas, 1994; beas et al., 2001).
Exigencia académica y atribución causal: ?qué pasa con la atribución al esfuerzo cuando hay una baja significativa en la exigencia académica?
Valenzuela Carreo,Jorge;
Educere , 2007,
Abstract: the empirical evidence which would support the thought that a significative low academic demand in schools would have negative efects over effort attribution from students, as explicative feature of academic achievement, is reported in this communication. the data was collected from a doctoral thesis and is treated as a fortune finding, since the significative low academic demand circumstances found were not intentional. the context from which this data was found is reported, the results are shown and the evidences are discussed

Método: Este artículo revisa la estructuración necesaria que se debe considerar durante el consenso para formular recomendaciones en las guías de práctica clínica. Conclusión: La técnica Delfos ayuda a obtener opiniones de una pregunta de investigación particular. Está basado en la premisa de que la inteligencia colectiva, desde el juicio individual, captura la opinión colectiva de un grupo de expertos sin necesidad de estar físicamente conectados. Introduction: Clinical practice guidelines should be based on the best available evidence.

Method: This paper reviews the structuring necessary for obtaining consensus in the process of formulating recommendations for clinical guidelines. Conclusion: The Delphi technique is a method for collecting opinions on a particular research question. It is based on the premise that pooled intelligence enhances individual judgment and captures the collective opinion of a group of experts without them being physically present.
