Ontologías materialistas y ontologías formalistas, alcances de la distinción
Román García Fernández
Revista Observaciones Filosóficas , 2012,
Abstract: We present the distinction between ontology and metaphysics and materialism-idealism opposition. It is considered that a process metaphysics substantialization opposite the ontology addresses constructs that limit. Also, it is considered that the term idealism is not correct to oppose materialism to the extent that seems to deny the use of the concept of idea by materialist philosophies, no matter who is right, especially since it involves renewed materialism philosophical materialism.
Expectativas del profesor sobre el rendimiento de sus alumnos a lo largo del curso: invariabilidad o adaptabilidad?
José María Román Sánchez,José Antonio Fernández García
Revista de Psicología y Educación , 2009,
Abstract: Se analiza la invariabilidad o adaptabilidad de las expectativas del profesor sobre el rendimiento de sus alumnos a lo largo del curso. Se contrastan con la evolución del rendimiento escolar de los alumnos y, en particular, con la de aquellos cuyo rendimiento se aparta notoriamente o incluso contradice las expectativas de rendimiento de sus profesores. Se ha utilizado un dise o longitudinal de panel con varias mediciones de las variables a los mismos sujetos: una muestra de 290 alumnos de secundaria. Los resultados muestran que las expectativas del profesor se mantienen relativamente estables a lo largo del curso a pesar de que el rendimiento de los alumnos mejora progresiva y significativamente. Cuando hay discrepancias entre “expectativas de rendimiento del profesor” y “calificaciones del alumno”, se resuelven “adaptando” el rendimiento del alumno a las expectativas que tienen sus profesores.

Abstract: Introduction: At least four techniques or approaches to minimize the risk of injury have been introduced. The correlation between techniques and the complication rate is controversial. The objective of the study is to report the incidence of laparoscopic entry associated injury, in relation to the used technique. Material and Methods: A retrospective study was conducted at the Hospital Espa? ol, in a 12-month period (2013). The medical records of all patients who underwent laparoscopic surgery were reviewed. Demographic and surgical variables were analyzed, comparing the results statistically through an analysis of variance (ANOVA). Results: A total of 792 cases were analyzed. The surgeries performed were: cholecystectomies (42%), appendectomies (26%), diagnostic laparoscopies (20%), ventral or inguinal hernioplasty (9%) and fundoplications (3%). The preferred approach was Hasson’s (79%) and Veres’s needle technique (14%), followed by classic closed (14%) and Palmer technique (2%). We documented six cases of laparoscopic entry associated injury (0.76%), four associated with the Hasson technique, one with Veress’s needle technique and one with direct approach technique were reported. The statistical analysis was performed considering the different techniques and their relation with the injuries. Analysis of variance did not reach statistical significance (p = 0.31). Conclusions: Among our data, the number of laparoscopic entry associated injuries, was less than 1%, and has a similar frequency to the reported literature. We did not find significant differences between the four laparoscopic entry techniques. There remains no clear evidence as to the optimal form of laparoscopic entry in the low-risk patient.

Abstract: Se evaluó la toxicidad aguda oral y la actividad antimicrobiana de una mezcla de aceites de hígado de tiburón, de las especies Rhincodon typu (tiburón ballena) y Galeocerdo cuvier (tiburón tigre), que habitan en zonas aleda as a las costas del litoral norte occidental de Cuba, para su posterior uso farmacéutico, debido a que presenta un alto contenido de vitaminas y de ácidos grasos, que le confieren actividad antioxidante y antiinflamatoria. El estudio de la toxicidad aguda oral demostró que la mezcla de aceites de hígado de tiburones, no provocó alteraciones macroscópicas en los órganos extraídos, ni síntomas tóxicos severos, ni mortalidad de ninguno de los animales empleados en el estudio a la dosis de 20 mL/kg. Los resultados del estudio de la actividad antimicrobiana demostraron una ligera actividad bacteriostática frente a K. pneumoniae; además una actividad antifúngica frente a Microsporum canis; y resistencia frente a C. albicans y T. mentagrophytes a las concentraciones evaluadas. The total acute toxicity and the antimicrobial activity of an oil mixtures from shark liver of Rhicodon typu (whale-shark) and Galeocerdo cuvier (tigger-shark) was assessed in species leaving in the adjacent costs of Cuban northern coastal for its subsequent pharmaceutical use due to its high content of vitamins and fatty acids and its antioxidant and anti-inflammatory activity. Study of oral acute toxicity demonstrated that oil mixture of shark liver hasn't macroscopic alterations in removed organs, severe toxic symptoms and on mortality of any animals used in study at 20 mL/kg dose. Study results of antimicrobial activity showed a slight bacteriostatic activity against K. pneumoniae and an antifungal activity against Microsporum canis, and a resistance against C. albicans and T. mentagrophytes at assessed concentrations.

Abstract: objectives: to estimate the prevalence of depressive symptoms in people older than 64 and to analyze their association with sociodemographic factors, frailty markers, and disabling diseases. methods: a survey-based, cross-sectional descriptive study was carried out. the sample was composed of 417 elderly people living in guadalajara (spain), selected on the basis of health cards. depressive symptoms were assessed using yesavage's test (cut-off: 6 or more items). the questionnaire contained sociodemographic and clinical items and evaluation scales for cognitive impairment, disability, and social risk. the frailty markers studied were age over 80 years old, female sex, cognitive impairment, disability, polypharmacy, comorbidity, and social risk. results: the prevalence of depressive symptoms was 19.7% (95% ci, 15.9-23.4) and clinical depression was diagnosed in 5% (95% ci, 2.3-7.7). depressive symptoms were more frequent in elderly individuals living in rural environments than in those living in urban areas (p < 0.05). these symptoms increased with age (p linear trend < 0.001) and were associated with social risk (p < 0.001), comorbidity (p < 0.001), cognitive impairment (p < 0.01), and disability (p < 0.05). when a multivariate statistical analysis was applied using logistic regression models, only comorbidity (odds ratio &(or&) = 2.38; 95% ci, 1.35-4.20) and social risk (or = 2.69; 95% ci, 1.50-4.83) were significantly associated. conclusions: the prevalence of depressive symptoms is very high in the elderly, four times higher than a diagnosis of clinical depression. social risk and comorbidity are strongly associated with depressive symptoms.
