Positivismo Liberal y Liberalismo Positivista. A propósito de un libro de Orlando Salazar Mora

IntroducciónPara empezar, no está de más una sincera felicitación al Centro de Investigaciones Histórica de la Universidad de Costa Rica, ya que se hacía urgente en nuestro medio. La obra del Profesor Orlando Salazar Mora, que pretendemos comentar, forma parte de ese encomiable esfuerzo y es importante aclarar que, ninguno de los argumentos aquí desarrollados, quiere abarcar a la colección (16 volúmenes) como un todo. Esto es convendiente señalarlo puesto que, con frecuencia, ciertas susceptibilidades de salón pudieran sentirse aludidas, cuando se trata de estudiar un libro que forma parte de un proyecto más vasto...

EL CIUDADANO TERRITORIAL, PROPÓSITO DE LA EDUCACIÓN GEOGRÁFICA

El planteamiento sobre el ciudadano territorial: propósito de la educación geográfica, emerge del interés temático en la ciudadanía vigente en la línea de investigación en Planeación, ciudadanía y territorio del grupo de investigación Medio Ambiente y Sociedad-MASO de la Universidad de Antioquia-Colombia y se concreta, entre otras, en la investigación de tesis doctoral en Educación denominada: Formación ciudadana en perspectiva de los estudios del territorio como estrategia pedagógica. Caso: PUI-NOR Medellín, Colombia, la cual tiene como propósito eje, fundamentar la formación ciudadana en la educación básica y media del sector oficial colombiano, a partir de la inclusión del potencial pedagógico proveniente de los estudios del territorio. El aspecto teórico del que nos ocupamos, es la constitución del ciudadano territorial como base de la ciudadanía orientada a contribuir con el fortalecimiento del proyecto político democrático. Al efecto, se parte de aceptar que no se cuenta con el ciudadano requerido para afianzar la democracia; que como éste no nace, sino que se hace, es necesario formarlo en contexto, de manera consciente e intencionada para que, ligado al territorio que habita, construye y semantiza, pueda desplegar junto a otros, una ciudadanía renovada orientada al respeto por la diferencia, al reconocimiento de la pluralidad, a la construcción de convivencia y, consecuentemente, a aportar en la consolidación de la democracia. La finalidad es contribuir a la educación geográfica en América Latina haciendo visibles y argumentando las posibilidades que otorga la formación ciudadana basada en la teoría de los procesos conscientes, en perspectiva de los estudios del territorio soportados en el enfoque de la geografía crítica, para constituir el ciudadano territorial que ha de potenciar la democracia, desde el ejercicio de su ciudadanía. La relación teórica entre estudios del territorio y formación ciudadana, desde los procesos conscientes y la geografía crítica para constituir el ciudadano territorial anhelado, es el aporte que se hace a la enseñanza de la geografía y de las ciencias sociales, motivación del eje temático sobre enseñanza y aprendizaje de la geografía, en el XIII EGAL, Costa Rica, 2011.

Desafíos contemporáneos para el socialismo en Cuba (A propósito de las reformas políticoeconómicas en la fase actual de la revolución)

This essay analyzes on the origin and impact of the amendment process currently undertaken by the Cuban government authorities considering it as the result of --what I call-- super structural imbalance. Such imbalance is caused by the application of the System for Management and Planning of the Economy. To our judgment, the process of amendment both structurally and super structurally conforms the new phase in the construction of the Socialism in the island from a coherent point of view to what it has been until now as a political constant of the revolution: the vindication of the human being as the promoter of its historical reality.

Sistematização do dimensionamento técnico e econômico de sistemas fotovoltaicos isolados por meio de programa computacional

One of the main referring subjects to the solar energy is how to compare it economically with other sources of energy, as much alternatives as with conventionals (like the electric grid). The purpose of this work was to develop a software which congregates the technical and economic main data to identify, through methods of microeconomic analysis, the commercial viability in the sizing of photovoltaic systems, besides considering the benefits proceeding from the proper energy generation. Considering the period of useful life of the components of the generation system of photovoltaic electricity, the costs of the energy proceeding from the conventional grid had been identified. For the comparison of the conventional sources, electric grid and diesel generation, three scenes of costs of photovoltaic panels and two for the factor of availability of diesel generation had been used. The results have shown that if the cost of the panels is low and the place of installation is more distant of the electric grid, the photovoltaic system becomes the best option.

Seed dispersal of Solanum thomasiifolium Sendtner (Solanaceae) in the Linhares Forest, Espírito Santo state, Brazil

The aim of this study was to analyse seed dispersal and establishment of Solanum thomasiifolium in an area of nativo vegetation in Espirito Santo state on the southeastern Brazilian coast. Ten species of birds, the crab-eating fox (Cerdocyon thous), and one species of lizard (Tropidurus torquatus) fed on S. thomasiifolium fruits and dispersed viable seeds in their faeces. The proportional contribution of each of these groups to seed dispersal was 77% (birds), 19% (crab-eating fox) and 4% (lizards). Ants also contributed to seed dispersal. More seeds were deposited in vegetation islands than in the surrounding open areas. Germination rates of seeds collected directly from fruit (control), bird droppings, the faeces of crab-eating foxes and lizards were, respectively, 64, 64, 53, and 80 %. Differences among these rates were all significant, except between birds and control. Lizards were important as seed carriers between nearby islands and they expelled a higher proportion of viable seeds. Birds and the crab-eating foxes did not enhance seed germination, but promoted seed dispersal over a wider area. Plant architecture, fruit productivity, fruit characteristics and the diversity of frugivores are important for the success of S. thomasiifolium in habitat colonization.

Modelos organizadores do pensamento: uma perspectiva de pesquisa sobre o raciocínio moral com adolescentes autores de infração

This article has the aim to expand the perspective of research in the field of morality. We present a proposal of morality study of outlaw teenagers according to Thinking Organizer Models Theory. Through the idea of complexity we search to understand the cognitive process in the elaboration of moral reasoning inside situations of conflict. With this perspective, we developed a research that aimed to identify which organizer models were applied by 20 outlaw male teenagers who abide by social punishment to solve the hypothetical moral conflicts. Through interviews we told them a situation of moral conflict that involved friendship relation, physical aggression and steal. We could identified several models which were joined in three categories. Such models reflected the diversity and regularity that are present inside the elaborated reasoning to solve the conflicts shown by us. We conclude that the diversity of organizer models identified shows the importance of the contents in the construction of moral reasoning.

As dimensões da linguagem em livros didáticos de inglês para o Ensino Fundamental I

This article aims at discussing and articulating views of language under sociocultural, dialogic and discourse perspectives, in order to present a theoretical framework as far as the analysis of textbooks of English as a foreign language for the Brazilian Ensino Fundamental I is concerned. Due to the limited number of studies in this field, to the still considerably structural approach of the English language teaching and learning in our country nowadays and to the important mediation role textbooks play in language education, we believe our work can contribute positively to the construction of critical and multiple literacies, which, in turn, can support an active and transformative educacional process in the present times.

A moradia estudantil universitária como tema na produção científica nacional

This study analyses the national scientific production about college students' residence halls. The country's main data bases and electronic sites of several Brazilian higher education institutions were checked and 23 studies, published between 2000 and 2009, were found. The results of our analysis point to different focuses, which can be grouped into three categories: students who live in residence halls, residence halls themselves and actions for student assistance. Although there is large foreign scientific production about college student housing, the national production on this theme is still scarce, and the idea of student residence halls as educational spaces is still very incipient. The study points out to the need for investigating the living conditions in these places, and the impacts of this kind of habitation on students. Considering that student housing is an institutional responsibility, these studies potentially subsidize measures for proper educational conditions for college students.

The use of fluorescence in situ hybridization in the diagnosis of hidden mosaicism: apropos of three cases of sex chromosome anomalies

FISH has been used as a complement to classical cytogenetics in the detection of mosaicism in sex chromosome anomalies. The aim of this study is to describe three cases in which the final diagnosis could only be achieved by FISH. Case 1 was an 8-year-old 46,XY girl with normal female genitalia referred to our service because of short stature. FISH analysis of lymphocytes with probes for the X and Y centromeres identified a 45,X/46,X,idic(Y) constitution, and established the diagnosis of Turner syndrome. Case 2 was a 21-month-old 46,XY boy with genital ambiguity (penile hypospadias, right testis, and left streak gonad). FISH analysis of lymphocytes and buccal smear identified a 45,X/46,XY karyotype, leading to diagnosis of mixed gonadal dysgenesis. Case 3 was a 47,XYY 19-year-old boy with delayed neuromotor development, learning disabilities, psychological problems, tall stature, small testes, elevated gonadotropins, and azoospermia. FISH analysis of lymphocytes and buccal smear identified a 47,XYY/48,XXYY constitution. Cases 1 and 2 illustrate the phenotypic variability of the 45,X/46,XY mosaicism, and the importance of detection of the 45,X cell line for proper management and follow-up. In case 3, abnormal gonadal function could be explained by the 48,XXYY cell line. The use of FISH in clinical practice is particularly relevant when classical cytogenetic analysis yields normal or uncertain results in patients with features of sex chromosome aneuploidy.

Aspectos da tomografia computadorizada craniana na neurocisticercose na infância

The authors present the analysis of 27 computed tomography scans (CT) of 18 children which were divided in three groups according to clinical and tomographic criteria. Group 1 was characterized mainly by epilepsy and calcifications. Group 2 was characterized by intracranial hypertension and several tomographic aspects: edema, cysts and nodules were seen in three patients; hydrocephaly and calcifications were seen in two patients and CT was normal in one patient. Group 3 had patients with epilepsy or headache and variable tomographic patterns. The results are discussed based on the available literature.

Função vísuo-espacial em paralisia cerebral e proposta de novo teste com a ajuda de computador

The first idea of this study is trat there may be a disturbance of the visuo-spatial function in cerebral palsy. This idea is based upon the theories of Luria and Piaget. The second idea of this study is that the computer can help the investigation of visuo-spatial function. With the intention of evaluating the spatial function in cerebral palsy, the literature related to these themes was revised. We justify the proposal of a new test to study visuo-spatial function. This test uses straight lines in four different orientations and the subject has to recognize and arrange them individually or sets of them. This was done through the use of pencil and papel, and computer. The results confirm that there is a spatial disturbance and that a better understanding of the subject's difficulties was made possible through the use of the computer and the Logo computer language.
