¿El museo como forma de "conocer la Historia"? El público interpreta la inmigración

El trabajo analiza cómo la exposición presentada en el Museo Nacional de la Inmigración fue aprehendida e interpretada por su público visitante. Dependiente de la Dirección Nacional de Migraciones, el Museo funcionó entre los años 2001 y 2009 en el edificio del antiguo Hotel de Inmigrantes (en Retiro). Para este estudio utilizamos más de 700 mensajes registrados en el Libro de Visitas del Museo, que fueron clasificados en nueve categorías, de acuerdo a los aspectos comunes que expresaban. A lo largo del análisis, el concepto de memoria se volvió fundamental para comprender los sentimientos y deseos expresados por el público que visitó la institución. Dentro de los temas que aparecieron en los mensajes, pudimos verificar la importancia que le atribuían los visitantes al Estado argentino por la construcción del Hotel, la recepción de los inmigrantes y, actualmente, por la preservación de su memoria y patrimonio; también se evidenció un agradecimiento a los inmigrantes, cuya "fuerza" y "esperanza" contribuyeron al desarrollo del país

Investigação da atividade apoptótica na abertura luminal dos ductos das glândulas salivares: análise comparativa entre modelo animal e humano

As glândulas salivares são estruturas essenciais para a manutenção da homeostase da cavidade oral pela síntese e secreção do fluido salivar. A disfunção ou perda permanente das glândulas salivares causadas por radioterapia, doenças inflamatórias ou desordens congênitas elevam principalmente o risco de infecções da mucosa oral e de estruturas dentárias, além de potencialmente prejudicar funções fisiológicas como fala, mastigação e paladar, diretamente interferindo na qualidade de vida dos indivíduos afetados. Os tratamentos atualmente disponíveis são apenas paliativos, ressaltando a necessidade de se compreender melhor os processos embriogênicos a fim de desenvolver novas estratégias terapêuticas capazes de regenerar as glândulas salivares. O princípio da formação das glândulas salivares baseia-se na coordenação de diversos processos morfogenéticos, e este trabalho foca particularmente em investigar a formação do espaço luminal do sistema de ductos, uma vez que a adequada abertura dos lumens é um processo essencial para a secreção salivar. Relata-se que a remoção das células centrais dos cordões sólidos epiteliais por morte celular apoptótica é o principal mecanismo de abertura do espaço luminal dos futuros ductos glandulares em camundongos. Porém, pouco se sabe sobre o controle temporal da apoptose durante o desenvolvimento glandular e sobre seu comportamento em glândulas salivares humanas. Neste trabalho, o perfil de expressão de diversas proteínas envolvidas na cascata apoptótica em glândulas salivares fetais humanas foi analisado de acordo com cada estágio morfogenético por imunoistoquímica (Bax, Bak, Bad, Bid, Bcl-2, Bcl-x, Bcl-xL, caspase-3 clivada, caspases-6, -7 e -9, apaf-1, survivina e citocromo c). As análises semi-qualitativas resultaram em negatividade apenas para as proteínas Bcl-2, Bad, Bid e caspase-3 clivada em todas as fases de desenvolvimento. A expressão nuclear de Bax e Bak foi identificada em presumidos espaços luminais em estágios precoces, enquanto Bcl-xL foi o fator antiapoptótico da família Bcl-2 que exibiu expressão nuclear mais importante. Caspases-6, -7 e -9 foram positivas em todas as fases, e a ausência de caspase-3 clivada sugere caspase-7 como principal caspase efetora da apoptose em desenvolvimento de glândulas salivares humanas. Ambos os componentes do complexo apoptossomo foram positivos durante o desenvolvimento glandular, e o inibidor survivina demonstrou mais positividade nuclear em estágios mais avançados. Ao observar a expressão de reguladores apoptóticos durante o desenvolvimento glandular humano, foram realizados experimentos funcionais com culturas de tecido glandular de camundongos para avaliar o papel das caspases durante a formação desta estrutura. Inicialmente detectou-se a atividade apoptótica em glândulas salivares de camundongos albinos no centro dos cordões epiteliais primários a partir de estágios precoces de desenvolvimento através de TUNEL e caspase-3 clivada. A partir disso, foi realizada a inibição apoptótica funcional in vitro durante o mesmo período, que resultou em ductos significativamente mais amplos e em defeitos morfológicos importantes nas estruturas luminal e acinar. Este trabalho evidenciou portanto atividade apoptótica durante a formação de glândulas salivares humanas e de camundongo, expressando-se em fases mais precoces do que reportadas anteriormente. Além disso, a ausência de Bad e Bid indica que a via intrínseca está mais ativa que a extrínseca, e distintos perfis de expressão da maioria das moléculas sugere adicionais funções não-apoptóticas durante a morfogênese glandular.

Brief of Amici Curiae Scholars of the Constitutional Rights of Children in Support of Petitioners in Obergefell v. Hodges

Supreme Court precedent establishes that the government may not punish children for matters beyond their control. Same-sex marriage bans and non-recognition laws (“marriage bans”) do precisely this. The states argue that marriage is good for children, yet marriage bans categorically exclude an entire class of children – children of same-sex couples – from the legal, economic and social benefits of marriage. This amicus brief recounts a powerful body of equal protection jurisprudence that prohibits punishing children to reflect moral disapproval of parental conduct or to incentivize adult behavior. We then explain that marriage bans punish children of same-sex couples because they: 1) foreclose their central legal route to family formation; 2) categorically void their existing legal parent-child relationships incident to out-of-state marriages; 3) deny them economic rights and benefits; and 4) inflict psychological and stigmatic harm. States cannot justify marriage bans as good for children and then exclude children of same-sex couples based on moral disapproval of their same-sex parents’ relationships or to incentivize opposite-sex couples to “procreate” within the bounds of marriage. To do so, severs the connection between legal burdens and individual responsibility and creates a permanent class or caste distinction.

The making and unmaking of heritage

Heritage is defined by history which is by nature multi layered. The passage of time and the perspectives it affords, enables and even necessitates constant reexamination and reinterpretation of history. What effect do changes in historical perspective then have upon the definition of heritage which relies on an understanding of its history? The present paper attempts to engage with the notion of heritage, criteria of its definition, and the mutable nature of such designations with specific reference to architectural constructions and historical cities that enjoy or have enjoyed in the past the status of a ‘World Heritage Site’. Examples such as the Louvre museum in Paris or the King’s Cross station in London make an interesting study as they not only allow insight into the past but reflect the changes and adaptation over a period of time. Multiple alterations, some very recently, have modified them extensively since the time they were accorded the ‘World Heritage Site’ status. The above examples are contrasted by sites ridden with conflict such as the Bamiyan Valley. This site has been placed under the ‘World Heritage In Danger’ list by UNESCO taking into account the destruction of the Buddha statues in the region. The act of vandalism itself has had dual implications. While causing an irreparable loss to mankind of its heritage, it also serves as an effective symbol of religious fanaticism that is a pressing concern of our times. The paper then moves on to explore the case of Dresden which lost its ‘World Heritage’ status with the construction of the Waldschlösschen Bridge. This is a particularly interesting case because with the absolute destruction of the city during the Second World War, it was necessary to reconstruct the historical city while simultaneously acknowledging and addressing the modern day requirements. During the reconstruction, with the readaptation of the spaces, it was almost impossible to replicate the original architectural program or to undertake such a large reconstruction project employing only the traditional techniques and materials. This essentially made it a new city constructed in the image of the old. The recent necessity of a growing city was met by the construction of a bridge that has caused it to lose its ‘World Heritage’ status. Finally, this paper endeavours to foster discussion of questions central to the definition of heritage such as what happens when we have to adapt a living space to avoid its deterioration and descent into dereliction by overuse. Does it necessarily lose its historical value? What exactly is Historical value?.

La museología en la encrucijada de los caminos

Durante los últimos años han aparecido un gran número de publicaciones sobre las perspectivas de evolución del mundo de los museos. La reflexión sobre el futuro de estas instituciones no es reciente: la prospectiva, método dirigido a elaborar posibles escenarios en el futuro, no es estrictamente hablando museológica, pero necesariamente interesa al museólogo interrogarse sobre el campo museal. A decir verdad, en su mayoría son profesionales del museo quienes han escrito sobre el tema (en el contexto museal) para adaptar la institución a los nuevos retos. Algunos museólogos, se han arriesgado a este ejercicio, de manera más o menos afortunada. El artículo pretende, después de presentar la literatura prospectiva sobre el museo durante los últimos cincuenta años, y de analizar los recientes resultados de los informes de prospectiva, interrogarse sobre la contribución específica de una reflexión museológica acerca del futuro de los museos más allá de los ejes clásicos (demografía, economía, nuevas tecnologías) que se utilizan con más frecuencia.

El papel de los museos en la sociedad actual: discurso institucional o museo participativo

Desde hace ya varias décadas se ha extendido un lema convertido en habitual año tras año: que los museos necesitan cambios y que, éstos, deben seguir produciéndose en el futuro para que estas instituciones sigan siendo significativas en la sociedad, es decir, para los ciudadanos a quienes representan y sirven. La cuestión de cómo afrontan los cambios es lo que verdaderamente ha dado lugar a reflexiones interesantes en el campo de la museología. No existe un enfoque único para una cuestión tan compleja, ya que está compuesta de múltiples capas que, en muchas ocasiones, son difícilmente acoplables. Sin embargo, en términos generales, podemos apuntar que va a ser en la exposición donde los nuevos planteamientos tendrán su desarrollo.

Intimate Ecologies: An exploration of the languages of contemporary exhibitions and making in museums and related cultural spaces in the UK

Intimate Ecologies considers the practice of exhibition-making over the past decade in formal museum and gallery spaces and its relationship to creating a concept of craft in contemporary Britain. Different forms of expression found in traditions of still life painting, film and moving image, poetic text and performance are examined to highlight the complex layers of language at play in exhibitions and within a concept of craft. The thesis presents arguments for understanding the value of embodied material knowledge to aesthetic experience in exhibitions, across a spectrum of human expression. These are supported by reference to exhibition case studies, critical and theoretical works from fields including social anthropology, architecture, art and design history and literary criticism and a range of individual, original works of art. Intimate Ecologies concludes that the museum exhibition, as a creative medium for understanding objects, becomes enriched by close study of material practice, and embodied knowledge that draws on a concept of craft. In turn a concept of craft is refreshed by the makers’ participation in shifting patterns of exhibition-making in cultural spaces that allow the layers of language embedded in complex objects to be experienced from different perspectives. Both art-making and the experience of objects are intimate, and infinitely varied: a vibrant ecology of exhibition-making gives space to this diversity.

Development and/or change of the notion of permanent object and operative causality: empirical evidence in the first year of life

This study examines the notion of permanent object during the first year of life, taking into account the controversy of two approaches about the nature of change: developmental change and cognitive change. Using a longitudinal/cross-sectional design, tasks adapted of the subscale of permanent object and operative causality of the Uzgiris-Hunt Scale (Uzgiris and Hunt, 1975) (Uzgiris & Hunt, 1975) were presented to 110 infants of 0, 3, 6 and 9 months-old, which reside in three cities of Colombia. The results showed three types of strategies: (a) Not resolution; (b) Exploratory and (c) Resolution, which follow different trajectories in children’s performance. This allows affirming that adaptive conquests of the cognitive development stay together with the variety of strategies. Using strategies reveals adjustments and transformations of action programs that consolidate the notion of permanent object not necessarily with age, but with self-regulatory processes. Empirical evidence contributes to the understanding of the relations between the emergence of novelty in the development and performance variability

Give or take: thoughts on museum collections as working tools and their connection with human beings

This paper proposes a look at museums from the perspective of sociomuseology, an area of research and practice under development in countries such as Portugal, Brazil and Spain. Sociomuseology was born from the Latin new museology tradition and is closely connected with the International Movement for a New Museology (MINOM/ICOM). The Lusofona University in Lisbon offers MA and PhD programmes in Sociomuseology. The University supports a research centre in Sociomuseology and publishes the journals Cadernos de Sociomuseologia, in Portuguese, and Sociomuseology, in English (for more information see http://tercud.ulusofona.pt.). Sociomuseology concerns the study of the social role of museums and of the continuous changes in society that frame their trajectories. The practice of sociomuseologists is based on their work with the different dimensions of social and community development from ecomuseums to networking and other ways of organizing social action in the 21st century in which heritage plays a strategic role.

An Evaluation of”Middle Ages Dead or Live?”The first interactive exhibition at the National Museum of History

This is a study conducted at, and for, the National Museum of History in Stockholm. The aim of the study was to confirm or disconfirm the hypothesis that visitors in a traditional museum environment might not take part in interactivity in an interactive exhibition. And if they do the visitors might skip the texts and objects on display. To answer this and other questions a multiple method was used. Both non participant observations and exit interviews were conducted. After a description of the interactive exhibits, theory of knowledge and learning is presented before the gathered data is presented. All together 443 visitors were observed. In the observations the visitors were timed on how much time they spent in the room, the time spent on the interactivity, texts and objects. In the 40 interviews information about visitors’ participation in the interactivity was gathered. What interactivity the visitor found easiest, hardest, funniest and most boring.The result did not confirm the hypothesis. All kinds of visitors, children and adults, participated in the interactivities. The visitors took part in the texts and objects and the interactive exhibits.

Absence or weak correlation between chewing side preference and lateralities in primary, mixed and permanent dentition

Objectives: To determine whether chewing side preference (CSP) is correlated to lateralities (handedness, footedness, eyedness and earedness) in primary, mixed and permanent dentitions.Design: Three-hundred subjects were divided into 3 groups: Group 1-100 children 3-5 years old, primary dentition; Group 2-100 children 6-12 years old, mixed dentition; Group 3 - 100 subjects 18-47 years old, permanent dentition. CSP was determined using a method developed by Mc Donnell et al.(9) Subjects were given a piece of gum and the position of the chewing gum was recorded 7 times as right or left. Subjects were classified as 'observed preferred chewing side' (OPCS) when they performed 5/7, 6/7 or 7/7 strokes on the same side. OPCS corresponded to the CSP. Laterality tests were performed for handedness, footedness, eyedness and earedness tasks. The Chi-square (chi(2)) and phi correlation (r) tests were used to investigate significant correlations between CSP and sidedness.Results: There was a significant correlation between chewing and earedness (p = 0.00), although there was weak positive correlation (r = 0.30) for primary dentition. There were significant correlations between chewing and handedness (p = 0.02; r = 0.25) and chewing and footedness (p = 0.02; r = 0.26), however, there were weak positive correlations for mixed dentition; there were significant correlations between chewing and handedness (p = 0.02; r = 0.26); chewing and footedness (p = 0.00; r = 0.33) and chewing and earedness (p = 0.01; r = 0.29); however, there were weak positive correlations for permanent dentition.Conclusion: It may be concluded that CSP can be significantly correlated with: earedness for primary dentition; handedness and footedness for mixed dentition; handedness, footedness and earedness for permanent dentition, but these are weak positive relationships. Future work on larger samples of left- and right-sided individuals is required to validate the findings. (C) 2012 Elsevier Ltd. All rights reserved.

Multifocal pattern electroretinography for the detection of neural loss in eyes with permanent temporal hemianopia or quadrantanopia from chiasmal compression

Aims To evaluate the ability of multifocal transient pattern electroretinography (mfPERG) to detect neural loss and assess the relationship between mfPERG and visual-field (VF) loss in eyes with chiasmal compression. Methods 23 eyes from 23 patients with temporal VF defects and band atrophy of the optic nerve and 21 controls underwent standard automated perimetry and mfPERG using a stimulus pattern of 19 rectangles, each consisting of 12 squares. The response was determined for the central rectangle, for the nasal and temporal hemifields (eight rectangles each) and for each quadrant (three rectangles) in both patients and controls. Comparisons were made using variance analysis. Correlations between VF and mfPERG measurements were verified by linear regression analysis. Results Mean +/- SD mfPERG amplitudes from the temporal hemifield (0.50 +/- 0.17 and 0.62 +/- 0.32) and temporal quadrants (superior 0.42 +/- 0.21 and 0.52 +/- 0.35, inferior 0.51 +/- 0.23 and 0.74 +/- 0.40) were significantly lower in eyes with band atrophy than in controls (0.78 +/- 0.24, 0.89 +/- 0.28, 0.73 +/- 60.26, 0.96 +/- 0.36, 0.79 +/- 0.26 and 0.91 +/- 0.31, respectively). No significant difference was observed in nasal hemifield measurements. Significant correlations (0.36-0.73) were found between VF relative sensitivity and mfPERG amplitude in different VF sectors. Conclusions mfPERG amplitude measurements clearly differentiate eyes with temporal VF defect from controls. The good correlation between mfPERG amplitudes and the severity of VF defect suggests that mfPERG may be used as an indicator of ganglion cell dysfunction.
