Teacher Education and the Targeting of Disadvantage  [PDF]
Bruce Burnett, Jo Lampert
Creative Education (CE) , 2011, DOI: 10.4236/ce.2011.25064
Abstract: This paper outlines the Exceptional Teachers for Disadvantaged Schools (ETDS) project which began in June 2010 with the aim of developing and documenting an Australian university-based teacher education program specifically focusing on the preparation of high quality teachers for the disadvantaged school sector. ETDS constitutes a novel model of teacher education targeting disadvantaged schooling in that the selection of participating pre-service teachers has been based on their proven academic performance over the first 2 years of their 4-year Bachelor of Education degree. ETDS has established a modified curriculum that better supports the on-campus training of this cohort while also targeting the role of field experience within partner disadvantaged school settings. This paper offers a rationale for the model, unpacks its various phases and provides a justification of the model’s selection criteria based on high academic achievement.
Vasculariza??o temporária de membros isquêmicos por meio de shunt arteriomedular: trabalho experimental
Poerschke, Ronaldo André;Silveira, Daniela Augustin;Lodi, Peterson;Titton, Wagner;Marx, Guilherme;Lampert, Alexandre Soares;
Jornal Vascular Brasileiro , 2012, DOI: 10.1590/S1677-54492012000100006
Abstract: background: the authors idealized a temporary shunt between the femoral artery and the medullar canal on long bones to keep the viability of acutely ischemic limbs, while waiting for a definitive treatment. objective: to assess the flow on temporary shunts between the femoral artery and the marrow canal of the tibia during two hours in experimental dogs, which had the femoral artery interrupted. methods: two groups with three dogs on the control group and six on the intervention group were allocated at random. the controls had the right femoral common artery interrupted. the intervention group received a shunt between the iliac external artery and the medullar canal of the right tibia in addition. after two hours, the measure of the ph, blood coloration, blood flow in sonar doppler on the ischemic limbs were performed. the lungs were withdrawn in thoracic block for anatomic-pathologic analyses. results: the capillary blood ph average of the limb extremities in the control group was 6.97 (±0.39) and in the intervention group was 7.25 (±0.46), with p<0.001, and the blood coloration in the intervention group kept the bright aspect in all animals. the shunts needed in average three irrigations with saline heparin solution to be kept unobstructed. the macroscopic and microscopic evaluation of the pulmonary tissue did not evidence fat emboli. conclusion: the artery osseous or artery medullar (marrow) shunt showed to be feasible on the technical point of view in the laboratory.
Influences of Plant Traits on Immune Responses of Specialist and Generalist Herbivores
Evan Lampert
Insects , 2012, DOI: 10.3390/insects3020573
Abstract: Specialist and generalist insect herbivore species often differ in how they respond to host plant traits, particularly defensive traits, and these responses can include weakened or strengthened immune responses to pathogens and parasites. Accurate methods to measure immune response in the presence and absence of pathogens and parasites are necessary to determine whether susceptibility to these natural enemies is reduced or increased by host plant traits. Plant chemical traits are particularly important in that host plant metabolites may function as antioxidants beneficial to the immune response, or interfere with the immune response of both specialist and generalist herbivores. Specialist herbivores that are adapted to process and sometimes accumulate specific plant compounds may experience high metabolic demands that may decrease immune response, whereas the metabolic demands of generalist species differ due to more broad-substrate enzyme systems. However, the direct deleterious effects of plant compounds on generalist herbivores may weaken their immune responses. Further research in this area is important given that the ecological relevance of plant traits to herbivore immune responses is equally important in natural systems and agroecosystems, due to potential incompatibility of some host plant species and cultivars with biological control agents of herbivorous pests.
Vertical distribution of zooplankton: density dependence and evidence for an ideal free distribution with costs
Winfried Lampert
BMC Biology , 2005, DOI: 10.1186/1741-7007-3-10
Abstract: Experiments were performed in large, indoor mesocosms (Plankton Towers) with a temperature gradient of 10°C and a deep-water algal maximum established below the thermocline. As expected, Daphnia aggregated at the interface between the two different habitats when their density was low. The distribution spread asymmetrically towards the algal maximum when the density increased until 80 % of the population dwelled in the cool, food-rich layers at high densities. Small individuals stayed higher in the water column than large ones, which conformed with the model for unequal competitors.The Daphnia distribution mimics the predictions of an IFD with costs model. This concept is useful for the analysis of zooplankton distributions under a large suite of environmental conditions shaping habitat suitability. Fish predation causing diel vertical migrations can be incorporated as additional costs. This is important as the vertical location of grazing zooplankton in a lake affects phytoplankton production and species composition, i.e. ecosystem function.The water column in a stratified lake provides vertical gradients of habitat qualities for zooplankton. Surface layers (epilimnion) and deep layers (hypolimnion) separated by a strong temperature gradient (thermocline) differ very much with respect to temperature, light, food availability and predation risk. Although zooplankton are defined as "floating" in the water column, their populations show distinct horizontal and vertical distribution patterns [1]. At least the vertical distribution is the result of active habitat choice. Diel vertical migration is a striking example of habitat shift in response to changing suitability. Large zooplankton leave the warm, lighted and often food-rich epilimnion during the day to dwell in the cold, dark hypolimnion where food may be of low quantity and poor quality, in order to avoid predation by visually hunting predators (fish). They return to the surface layers at night when the predation
(Re)crear la universidad: una premisa urgente
Lampert, Ernani;
Perfiles educativos , 2009,
Abstract: this bibliographical study has as purpose to stress the urgent necessity of (re)creating the university within the current political, economic, social, technological and cultural context of latin america. taking into account the current context of neoliberal ideology and the globalization process that consider education as a merchandise, the author proposes a new way to conceive some of the most problematical matters that have been accompanying university throughout its whole history: mission, autonomy, government, financing, curriculum approach, research, update of the human resources and institutional assessment. this aspects are analyzed in a synoptic way and the author shows, within the current university structure, possible alternative paths in order to reach that university rethinks its own convictions and practices in order to achieve a better quality of teaching and to become more helpful to the sustainable development and to the improvement of the life conditions of the society as a whole. finally the author presents, as a possible reflection, some matters that could be retaken for future researches.

Perfiles educativos , 2005,
Abstract: this article analyzes the decline of brazilian university system due to the neoliberal policies. it consists of two parts, which are tightly connected. the first part gives us a contextualization and a theoretical approach of the problem, based on a short historical introduction in which the author emphasizes some of the factors which influenced the development of higher education during the colonial, imperial and republican period. according to the vision of several authors, it analyzes polemic aspects and chronicles about the brazilian university. the second part contains a description of the methodology that have been used for this research, for which the object of study were the teachers, students and civil servants at the federal universities within the state of rio grande do sul. it also gives an overview of the proceedings and and some of the inferences that are made possible by this study as a basis for analysis and reflexion.
Posmodernidad y universidad: ?una reflexión necesaria?
Lampert, Ernani;
Perfiles educativos , 2008,
Abstract: this study approaches a complex, up-to-date and polemic set of problems which has a direct reflection on the pedagogical dimensión of the university. consequently, it affects the quality of the university teaching. firstly the author analyzes in a deep manner and according to several authors, the word post-modernity which is comprehensive and contradictory. based on the literature and on different areas of human knowledge he characterizes the post-modern mega paradigm. in the second part, he analyzes the university as the main manager of science and due to the changes which happened in the last decades, this university is without a paradigm which anchors it. as it is very questioned, yet recognizing that there are exceptions, it cannot attend the need of a each time more competitive society. in the end, as an example of reflection, he brings some considerations consequential to the study.

(Re)crear la universidad: una premisa urgente
Ernani Lampert
Perfiles educativos , 2009,
Abstract: Este estudio, de cu o bibliográfico, se propone mostrar la necesidad urgente de (re)crear la universidad dentro del actual contexto político, económico, social, tecnológico y cultural de América Latina. Teniendo presente el contexto de la ideología neoliberal y del proceso de globalización que consideran a la educación como una mercancía, se plantea una nueva manera de ver algunas cuestiones problemáticas que acompa an a la universidad a lo largo de su historia: misión, autonomía, gestión, financiación, abordaje curricular, investigación, actualización de recursos humanos y evaluación institucional. Se analizan esos aspectos de manera sinóptica y se apuntan, dentro de la actual estructura universitaria, caminos alternativos para que la universidad repiense sus convicciones y prácticas en busca de una mejor calidad de la ense anza, y contribuya desde el desarrollo sostenible a mejorar las condiciones de vida de la sociedad como un todo. Finalmente se presentan, a título de reflexión, algunas cuestiones que se espera sirvan para futuras investigaciones.
