La Segunda Guerra Mundial y las atrocidades cometidas en investigaciones con los prisioneros en los campos de concentración nazis y japoneses, despertaron la conciencia por el desarrollo de los derechos humanos que se habían conquistado paulatinamente a lo largo de la historia. Por ello se conforman una serie de leyes, normas y declaraciones donde se tratan los aspectos bioéticos en los ensayos clínicos. Se debe prestar vital atención a la relación médico-paciente en el curso de las investigaciones y considerar la (...) relación beneficio/riesgo cuando se va a experimentar en seres humanos. La retinopatía diabética proliferativa es una de las afecciones oftalmológicas que más ensayos ha suscitado. El objetivo de este trabajo consiste en analizar algunos aspectos éticos en la experimentación en pacientes con esta afección. The Second World War and the atrocities committed in research with prisoners in Japanese and Nazi concentration camps, awakened consciousness for the development of human rights that had gradually been conquered throughout history. That´s why a series of laws, rules and statements that deal with bioethical aspects in clinical trials, were passed. Special attention must be given to the doctor-patient relationship during the research and consider the benefit/risk ratio when conducting experiments on human beings. Proliferative Diabetic Retinopathy is one of the ophthalmological disorders that has given rise to more trials. The research goal is to analyze some ethical aspects when experimenting on patients with this condition. (shrink)

Se realiza una revisión bibliográfica con el objetivo de analizar los diferentes códigos éticos y deontológicos internacionales, regionales y nacionales de los que se nutre la especialidad de psiquiatría. Se concluye que el comportamiento ético se basa en el sentido de la responsabilidad individual de cada psiquiatra hacia cada paciente y en la capacidad de ambos para determinar cuál es la conducta correcta y más apropiada. Las normas externas y las directrices, tales como los códigos de conducta profesional, las aportaciones (...) de la ética y de las normas legales, no garantizan por sí solas la práctica ética de la medicina, pero constituyen un importante marco referencial. A literature review was performed with the objective of analyzing the various international, regional and national ethical and deontological codes that the psychiatry specialty feeds on. It is concluded that ethical behavior is based on the sense of individual responsibility of each psychiatrist to each patient and the ability of both to determine what the correct and appropriate behavior is. External standards and guidelines, such as professional codes of conduct, the study of ethics and legal standards alone do not guarantee the ethical practice of medicine but are an important framework.

Photography is clearly not a mirror of daily life: that images are constructions is especially obvious in 19th-century studio portrait photography. This book explores how indigenous Iranian photographers constructed their own realities in contrast to howforeign photographers constructed Iranians' realities. Through an in-depth comparative visual analysis of 19th-century Iranian portrait photography and Persian painting, the author arrives at the insight that aesthetic preferences correlate with socio-cultural habits and practices in writing, reading and looking. Subsequently, she advocates for a place in (...) a global history of photography for those unknown, local photo histories and for the indigenous photographers who produced them. (shrink)

El presente monográfico recoge trabajos en torno al tema que da título al mismo: “Teorías de la justicia y tribunales internacionales de derechos humanos”. Dos son las consideraciones que, de entrada, deben hacerse sobre el mismo.

Introducción: El embarazo, aborto, las infecciones de transmisión sexual incluido el Virus de Inmuno Deficiencia Humana, se han convertido en problemas sanitarios de mayor vulnerabilidad en jóvenes. Objetivo: Describir las conductas de riesgo y prevalencia de problemas sexuales y reproductivos de estudiantes universitarios. Método: Investigación descriptiva, el universo estuvo constituido por alumnos de dos grupos de segundo semestre; el grupo de estudio conformado por la totalidad de estudiantes de la Facultad de Salud Pública ; y el control seleccionado mediante una (...) muestra aleatoria de estudiantes del resto de las facultades, se realizó esta selección con el propósito de valorar la homogeneidad de las variables entre los grupos. Resultados: Existe homogeneidad en la mayoría de conductas de riesgo y problemas sexuales en los grupos, en consecuencia estas variables no están influenciadas por la pertenencia a la Facultad de Salud Pública. Se evidencian conductas de riesgo como: inicio temprano de relaciones sexuales, múltiples parejas, infidelidad, relaciones sexuales ligadas al consumo de sustancias, dificultades con el uso de métodos anticonceptivos o de protección; se encontró prevalencia de problemas como: experiencia de embarazos, la mayoría no planeados, abortos inducidos y presencia de infecciones de transmisión sexual. Conclusiones: Existe vulnerabilidad en la salud sexual y reproductiva de los jóvenes universitarios independientemente de la formación que reciben, por tanto, emerge la necesidad de buscar alternativas integrales de promoción, prevención y educación sexual integral. Introduction: Pregnancy, abortion, sexually transmitted infections including Human Immunodeficiency Virus, have become a health problem of more vulnerable in young people. Objective: To describe risk behaviors and prevalence of sexual and reproductive problems of university. Method: Descriptive study, the universe consisted of students from two groups of second semester; the study group is conformed by students of the Public Health Faculty ; and control selected by a random sample of students from other faculties, in order to assess the homogeneity of the variables between groups. Results: Homogeneity exists in most risk behaviors and sexual problems in groups, therefore these variables are not influenced by membership in the Public Health Faculty. Risk behaviors as evidence: early initiation of sexual activity, multiple partners, infidelity, sexual relationship linked to substance consumption, which prevails alcohol, together with the non-use or inappropriate use of contraception or protection; experience of pregnancy, most unplanned, induced abortions and the presence of sexually transmitted infections: prevalence of problems as found. Conclusions: There is vulnerability in sexual and reproductive health of young students regardless of their training, thus emerges the need to find alternatives comprehensive promotion, prevention and comprehensive sex education.

This paper proposes an intermediate account of personhood, based on the capacity to participate in intersubjective interactions. We articulate our proposal as a reply to liberal and restrictive accounts, taking Mark Rowlands’ and Stephen Darwall’s proposals as contemporary representatives of each view, respectively. We argue that both accounts fall short of dealing with borderline cases and defend our intermediate view: The criteria of personhood based on the second-person perspective of mental state attribution. According to it, a person should be able (...) to participate in intersubjective interactions. We apply our proposal to the borderline cases of non-human primates and human infants. (shrink)

Fundamental motor skills of children can be affected by different variables, such as executive functions, gender and relative age. However, the effects of these variables on FMS have been scarce studied, especially in early childhood, and show inconsistent results. To clarify these relationships, this study was carried out. Its aim was to analyze whether EF, gender and relative age influenced FMS in 43 Spanish kindergarteners. A multimethod and mixed methods approach was used. Kindergarteners’ teachers completed the Childhood Executive Functioning Inventory (...) to know the children level of EF. Kindergarteners’ parents complimented ad hoc questionnaire reporting the children gender and birth data. A Nomothetic/Punctual/Multidimensional observational design was used to observe children FMS in their habitual motor sessions at school. Two-way ANOVAs were performed to know the independent and interactive effects of working memory level, inhibition control level, gender and relative age on FMS. Results showed these variables have independent and interactive effects on some FMS, but not on others. FMS influenced by these variables vary depending what independent variable is/are considered. Therefore, it can be concluded that the influences of teacher-rated EF, gender and relative age on observed FMS in kindergarteners are complex and specific. Results obtained must be taken into to design and implement instructional and intervention strategies, as well as educational and sport policy changes, especially in early childhood, when FMS are more malleable.

Se analiza el papel del pathos como condición de emergencia del logos y de la episteme, lo cual nos lleva a reconocer que a la par de una concepción "intelectualista" de la teoría platónica del conocimiento, en la que es necesaria la supresión de todos los elementos irracionales que nublan el juicio, existe otra perspectiva, sobre todo sustentada en el Fedro, en la cual el pathos, expresado sea como asombro, como sufrimiento o como manía amorosa, no es solamente una etapa (...) que se debe superar para acceder a la intuición de las Formas, sino que ella misma se convierte en una experiencia cognitiva que devuelve al conocimiento su carácter humano. We analyze the role of pathos as emergency condition for both, logos and episteme, which leads us to recognize that along with an intellectual conception of the Platonic theory of knowledge, that demands to abolish all irrational elements which cloud the judgment, there is another perspective, especially supported by the Phaedrus, in which pathos, understood as astonishment, suffering or love madness, is not just a stage to overcome in order to arrive to the intuition of Forms, but it becomes itself a cognitive experience that gives back to knowledge its human nature.

In eukaryotic cells the nucleus and its contents are separated from the cytoplasm by the nuclear envelope. Macromolecules, as well as smaller molecules and ions, can cross the nuclear envelope through the nuclear pore complex. Molecules greater than approx. 60 kDa and containing a nuclear localization signal are actively transported across the nuclear membranes, but there has been little evidence for regulatory mechanisms for smaller molecules and ions. Recently, diffusion across the nuclear envelope has been observed to be regulated by (...) nuclear cisternal Ca2+ concentrations. Following depletion of Ca2+ from the nuclear store by inositol 1,4,5‐trisphosphate or Ca2+ chelators, a fluorescent 10 kDa marker molecule was no longer able to enter the nucleus. Distinct conformational states of the nuclear pore complexes depended on the Ca2+ filling state of the nuclear envelope, supporting the assumption that a switch in the conformation of the nuclear pore complex may control the transport of intermediate‐sized molecules across the nuclear envelope. Thus nuclear Ca2+ stores may regulate the conformational state of the nuclear pore complex, and thereby passive diffusion of molecules between the cytosol and the nucleoplasm. The physiological significance of this finding is currently unknown. (shrink)

Business Ethics: A European Review, EarlyView.

The purpose of this study was to examine student perceptions of teaching behavior. Additionally the aim was to examine if teacher characteristics (educational level, gender, and teaching experience) could explain differences in student perceptions of their teachers. Teaching behavior was studied from the research on teaching and teacher effectiveness perspective. Secondary students (N = 7,114), taught by 410 teachers in Spain, participated in the study. Survey data were analyzed using non-parametric tests, Kruskal-Wallis, U Mann-Whitney with Bonferroni correction, and the analysis (...) of effect sizes. Furthermore, a regression model was applied. Results showed that teaching behavior was perceived as sufficient to good, depending on the teaching behavior domain. Results indicated interesting differences between lower secondary education, upper secondary education and vocational education and training teachers. The effect size values (rU statistic) ranged between 0.43 and 0.63, highlighting the significant effect of teachers’ teaching experience on the six teaching skills domains: learning climate, efficient classroom management, clarity of instruction, activating teaching, differentiation, and teaching learning strategies. Those teachers with less teaching experience were the ones who showed higher scores. Findings from the regression model showed that educational level had a significant predictive effect on the six teaching skills domains, mainly for male teachers. However, in several domains female teachers were perceived by students to outperform their male counterparts. (shrink)

How might artificial neural networks (ANNs) inform cognitive science? Often cognitive scientists use ANNs but do not examine their internal structures. In this paper, we use ANNs to explore how cognition might represent musical properties. We train ANNs to classify musical chords, and we interpret network structure to determine what representations ANNs discover and use. We find connection weights between input units and hidden units can be described using Fourier phase spaces, a representation studied in musical set theory. We find (...) the total signal coming through these weighted connection weights is a measure of the similarity between two Fourier structures: the structure of the hidden unit's weights and the structure of the stimulus. This is surprising because neither of these Fourier structures is computed by the hidden unit. We then show how output units use such similarity measures to classify chords. However, we also find different types of units—units that use different activation functions—use this similarity measure very differently. This result, combined with other findings, indicates that while our networks are related to the Fourier analysis of musical sets, they do not perform Fourier analyses of the kind usually described in musical set theory. Our results show Fourier representations of music are not limited to musical set theory. Our results also suggest how cognitive psychologists might explore Fourier representations in musical cognition. Critically, such theoretical and empirical implications require researchers to understand how network structure converts stimuli into responses. (shrink)

Handwriting is a complex activity that involves continuous interaction between lower-level handwriting and motor skills and higher-order cognitive processes. It is important to allocate mental resources to these high-order processes since these processes place a great demand on cognitive capacity. This is possible when lower-level skills such as transcription are effortlessness and fluent. Given that fluency is a value in virtually all areas of academic learning, schools should provide instructional activities to promote writing fluency from the first stages of learning (...) to write. In an effort to determine if teaching handwriting enhances writing fluency, we conducted a systematic and meta-analytic review of the writing fluency intervention literature. We selected 31 studies: 21 true and quasi-experimental studies, 4 single-group design, 3 single-subject design, and 3 non-experimental studies, conducted with K-6 students in a regular school setting. A total of 2,030 students participated in these studies. When compared to no instruction or non-handwriting instructional conditions, teaching different handwriting intervention programs resulted in statistically significant greater writing fluency. Moreover, three specific handwriting interventions yielded statistically significant results in improving writing fluency, when compared to other handwriting interventions or to typical handwriting instruction conditions: handwriting focused on training timed transcription skills, multicomponent handwriting treatments, and performance feedback. There were not enough data to calculate the impact of sensory-motor and self-regulated strategy handwriting interventions on writing fluency. The significance of these findings for implementing and differentiating handwriting fluency instruction and guiding future research will be discussed. (shrink)

El objetivo de este artículo es analizar la asociación entre el desarrollo de una práctica docente reflexiva y el fomento de la innovación educativa. Para ello, se siguió una metodología mixta con alcance exploratorio-descriptivo y una recolección de datos de corte transversal. La vertiente cuantitativa contempló la visión de docentes de aula y docentes directivos (...) (n=123) de cinco centros escolares chilenos, quienes expresaron sus opiniones en un cuestionario ad hoc. En la vertiente cualitativa se realizaron entrevistas semiestructuradas a 18 docentes de aula y docentes directivos de los centros involucrados en esta investigación. Para sus relatos se realizó un análisis de contenido lo que permitió identificar patrones, temas convergentes y divergentes, considerando el contexto escolar como marco de refencia. Los resultados revelan una asociación entre una práctica docente reflexiva, donde el profesorado incorpora en su labor elementos y prácticas asociadas a un nivel de reflexión crítica, y su participación en proyectos de innovación educativa.
