Com que conteúdo eu vou ao currículo que você me convidou? Geografia e história no ensino fundamental

This paper intends to reflect on the search, in the process of teaching formation, of pre-defined contents for the teaching of Geography and History in the series of primary school. This desire for clarity about the appropriated contents for the various series often overshadows the real need to clarify what is the goal of teaching this or that content. It is necessary, in the teacher training, resume and historically contextualize this search for curriculum contents. The risk of prioritizing the discussion about contents is transforming the contents itself into the content goals of education. Reifying the contents contributes to the common process of disconnect teaching from learning. In this case, the educational process becomes a contest of teaching contents, not bothering if these contents were or not learned by the students, which makes education extremely conservative. This phenomenon has it origins in the 1970s, during the curriculum discussions of the various areas of school knowledge. Since then, the concept of didactic transposition has been questioned progressively, in which the curricula were designed as adapted teaching to lower levels of scientific knowledge produced in universities – the place for higher education. The school knowledge, since the 1970s, is considered as autonomous. In other words, knowledge in dialogue with university science, but with typical characteristics of education in school systems. If the curriculum of primary and secondary educations is not the result of the didactic transposition, what content it should be made of? The current paper touches this issue, but subordinates it to most relevant questions about the purposes of learning in inseparable connection with teaching.

Sobre a identidade do Centro de Educação Matemática (CEM): acidentes de uma leitura cartesiana

In this paper we present results of research conducted on the constitution of the identity of CEM (Centre for Mathematics Education), a group of mathematics teacher educators from the city of São Paulo, Brazil (1984-1997). We emphasize the processes of constitution of CEM’s identities, on the perspective of Oral History in Mathematics Education, of the Model of Semantic Fields and of theories of identities. As part of the broader endeavor of examining possibilities for constituting identities for the group, from several theoretical standpoints, here we report an exercise on constituting the identity of CEM from a Cartesian standpoint; the overall assumption is that we are not properly interested in what CEM is or was, but on the possibilities themselves. We argue that such analysis leads to an understanding of the group as being an accident involving the individual identities of its members but not to an understanding of CEM’s group identity as such.

Desigualdade social no Brasil: as principais mudanças nos governos Lula

This monograph will focus on the social policies implemented by the Federal Government during the government of Luis Inácio Lula da Silva. The aim of this study is to analyze the main changes in social inequality indicators in the period 2003 - 2010. In the first chapter, we present some ideas of poverty meaning and its history in Brazil. The second chapter is dedicated to the most important cash transfer program in the history of the country, the Bolsa Familia program, and finally, in Chapter 3, is highlighted as stocks in the labor market also contributed to improve social indicators in Brazil and lift millions out of poverty and extreme poverty, such as increasing the level of formal job creation and the real increase in the minimum wage

South Carolina Home Economics Association Records - Accession 22

This collection is a valuable source on home economics history in South Carolina during the twentieth century. While there is information on the SCHEA from its beginning in 1914 to 1980, the actual records do not start until 1920. An outline of what the South Carolina Home Economics Association was doing from 1914 to 1920, is provided in the “historical file” (see Box 1, folders 1 to 4). The inclusive dates for a particular series may vary and, for most series, the records are incomplete. The collection contains all the records normally created by an organization, including constitutions, correspondence, minutes, reports, handbooks, etc. A wide variety of research topics could be developed from the records, including the SCHEA’s impact on the legislative process in South Carolina (e.g. the passage of the bill for the enrichment of cornmeal and grits in 1943), its cooperation and relationship with relief agencies in the state and its role in improving child health during the 1930s.

Elderly Individuals with Diabetes: Adding Cognitive Training to Psychoeducational Intervention

The present research examined the effects of a cognitive training program combined with psychoeducational intervention for diabetic elderly patients. Specifically, it aimed at assessing the effects of an eight-session cognitive training and educational program in diabetic elderly individuals and investigating changes in their awareness about specific aspects of diabetes. The final sample consisted of 34 individuals-19 in the experimental group (EG) and 15 in the control group (CG), all residing in the eastern region of the city of Sao Paulo. The protocol included clinical and sociodemographic questions; the Diabetes Attitudes Questionnaire (ATT-19); Diabetes Knowledge Scale (DKN-A); Mini Mental State Examination (MMSE); Verbal Fluency-animal category (VF); Geriatric Depression Scale (GDS); Short Cognitive Performance Test (SKT); and the Rivermead Behavioral Memory Test (RBMT). Results pointed to a significant difference between the two groups for the ATT-19, DKN, and SKT-memory and SKT-total, and a marginally significant difference for the RBMT history in the posttest. As for the remaining cognitive variables, no changes were observed. Retest effects were not observed in the CG. We concluded that cognitive training combined with psychoeducational intervention in diabetic elderly individuals may be effective in producing cognitive gains as well as attitude and knowledge improvement concerning diabetes mellitus (DM).

Late-onset social anxiety disorder following traumatic brain injury

Background: Neuropsychiatric sequelae are the predominant long-term disability after traumatic brain injury (TBI). This study reports a case of late-onset social anxiety disorder (SAD) following TBI. Case report: A patient that was spontaneous and extroverted up to 18-years-old started to exhibit significant social anxiety symptoms. These symptoms became progressively worse and he sought treatment at age 21. He had a previous history of traumatic brain injury (TBI) at age 17. Neuroimaging investigations (CT, SPECT and MRI) showed a bony protuberance on the left frontal bone, with mass effect on the left frontal lobe. He had no neurological signs or symptoms. The patient underwent neurosurgery with gross total resection of the lesion and the pathological examination was compatible with intradiploic haematoma. Conclusions: Psychiatric symptoms may be the only findings in the initial manifestation of slowly growing extra-axial space-occupying lesions that compress the frontal lobe from the outside. Focal neurological symptoms may occur only when the lesion becomes large. This case report underscores the need for careful exclusion of general medical conditions and TBI history in cases of late-onset SAD and may also contribute to the elucidation of the neurobiology of this disorder.

An Extreme Case of Plant-Insect Codiversification: Figs and Fig-Pollinating Wasps

It is thought that speciation in phytophagous insects is often due to colonization of novel host plants, because radiations of plant and insect lineages are typically asynchronous. Recent phylogenetic comparisons have supported this model of diversification for both insect herbivores and specialized pollinators. An exceptional case where contemporaneous plant-insect diversification might be expected is the obligate mutualism between fig trees (Ficus species, Moraceae) and their pollinating wasps (Agaonidae, Hymenoptera). The ubiquity and ecological significance of this mutualism in tropical and subtropical ecosystems has long intrigued biologists, but the systematic challenge posed by >750 interacting species pairs has hindered progress toward understanding its evolutionary history. In particular, taxon sampling and analytical tools have been insufficient for large-scale cophylogenetic analyses. Here, we sampled nearly 200 interacting pairs of fig and wasp species from across the globe. Two supermatrices were assembled: on an average, wasps had sequences from 77% of 6 genes (5.6 kb), figs had sequences from 60% of 5 genes (5.5 kb), and overall 850 new DNA sequences were generated for this study. We also developed a new analytical tool, Jane 2, for event-based phylogenetic reconciliation analysis of very large data sets. Separate Bayesian phylogenetic analyses for figs and fig wasps under relaxed molecular clock assumptions indicate Cretaceous diversification of crown groups and contemporaneous divergence for nearly half of all fig and pollinator lineages. Event-based cophylogenetic analyses further support the codiversification hypothesis. Biogeographic analyses indicate that the present-day distribution of fig and pollinator lineages is consistent with a Eurasian origin and subsequent dispersal, rather than with Gondwanan vicariance. Overall, our findings indicate that the fig-pollinator mutualism represents an extreme case among plant-insect interactions of coordinated dispersal and long-term codiversification.

Innovación educativa en la docencia universitaria de la Historia: balance de una década en la ULPGC (2002-2012)

[ES] El presente trabajo analiza las acciones de innovación educativa realizadas en el seno de la Facultad de Geografía e Historia de la Universidad de Las Palmas de Gran Canaria en la década que transcurre entre los años 2002 y 2012. En una primera fase (2002-2009), previa a la constitución formal de los Grupos de Innovación Educativa (GIE) en la ULPGC, las actividades de innovación educativa se realizaron de manera coordinada por un grupo de trabajo formado por varios profesores de los departamentos de Geografía y Ciencias Históricas. A partir de la constitución de los GIE y, en particular, con la creación del GIE Clío 2.0, se inició una nueva fase (2009-2012) que, al igual que la anterior, ha contado con el apoyo del Decanato de la Facultad de Geografía e Historia.

La Epigrafía, de ciencia auxiliar a ciencia histórica

[ES]La Epigrafía es una ciencia historiográfica indispensable en la formación de los historiadores que, desde hace siglos, forma parte de las mal denominadas “ciencias auxiliares” de la Historia. En este trabajo se analiza el concepto de Epigrafía, el método epigráfico y el recorrido historiográfico que esta ciencia ha desarrollado a lo largo de la Historia, con el fin de aproximar al lector a los rudimentos de esta ciencia historiográfica, con especial referencia a la labor investigadora que se ha desarrollado en España. El estudio finaliza con un acercamiento a la situación actual de la Epigrafía, no solo en la formación universitaria de las futuras generaciones de historiadores, sino en el análisis de las líneas de investigación y proyectos más importantes que están en curso en la actualidad.

Clinicopathological and molecular characterization of gastroesophageal junction (GEJ) adenocarcinoma before age of 40 years

Gastroesophageal junction (GEJ) adenocarcinoma are uncommon before age of 40 years. While certain clinical, pathological and molecular features of GEJ adenocarcinoma in older patients have been extensively studied, these characteristics in the younger population remain to be determined. In the recent literature, a high sensitivity and specificity for the detection of dysplasia and esophageal adenocarcinoma was demonstrated by using multicolor fluorescence in situ hybridization (FISH) DNA probe set specific for the locus specific regions 9p21 (p16), 20q13.2 and Y chromosome. We evaluated 663 patients with GEJ adenocarcinoma and further divided them into 2 age-groups of or= 50 years, rispectively. FISH with selected DNA probe for Y chromosome, locus 9p21 (p16), and locus 20q13.2 was investigated with formalin fixed and parassin embedded tissue from surgical resections of 17 younger and 11 older patients. Signals were counted in > 100 cells with each given histopathological category. The chromosomal aberrations were then compared in the 2 age-groups with the focus on uninvolved squamous and columnar epithelium, intestinal metaplasia (Barrett's mucosa), glandular dysplasia, and adenocarcinoma. Comparisons were performed by the X2 test, Fisher's exact test, Student's t-test and Mann-Whitney U-test as appropriate. Survival was estimated by the Kaplan-Meier method with univariate analysis by the log-rank. Significance was taken at the 5% level. There was no difference in the surgical technique applied in both age groups and most patients underwent Ivor Lewis esophagectomy. Among clinical variables there was a higher incidence of smocking history in older patient group. We identified a progressive loss of Y chromosome from benign squamos epithelium to Barrett's mucosa and glandular dysplasia, and, ultimately, to a near complete loss in adenocarcinoma in both age groups. The young group revealed significantly more losses of 9p21 in both benign and neoplastic cells when compared to the older patients group. In addition, we demonstrated an increase in the percentage of cells showing gain of locus 20q13.2 with progression from benign epithelium through dysplasia to adenocarcinoma with almost the same trend in both the young and the older patients. When compared with the older age-group, younger patients with GEJ adenocarcinoma possess similar known demographics, environmental factors, clinical, and pathologic characteristics. The most commonly detected genetic aberrations of progressive Y chromosomal loss, 9p21 locus loss, and 20q13 gains were similar in the younger and older patients. However the rate of loss of 9p21 is significantly higher in young patients, in both the benign and the neoplastic cells. The loss of 9p21, and possibly, the subsequent inactivation of p16 gene may be one of the molecular mechanisms responsible for the accelerated neoplastic process in young patients.

Application of numerical methods to earthquake stability assessment of slopes

Questo documento descrive gran parte del lavoro svolto durante un periodo di studio di sei mesi all’International Centre for Geohazards (ICG) di Oslo. Seguendo la linea guida dettata nel titolo, sono stati affrontati diversi aspetti riguardanti la modellazione numerica dei pendii quali l’influenza delle condizioni al contorno e delle proporzioni del modello, la back-analysis di eventi di scivolamento e l’applicazione delle analisi di stabilità monodimensionali. La realizzazione di semplici modelli con il programma agli elementi finiti PLAXIS (Brinkgreve et al., 2008) ha consentito di analizzare le prestazioni dei modelli numerici riguardo all’influenza delle condizioni al contorno confrontandoli con un calcolo teorico del fattore di amplificazione. Questa serie di test ha consentito di stabilire alcune linee guida per la realizzazione di test con un buon livello di affidabilità. Alcuni case-history, in particolare quello di Las Colinas (El Salvador), sono stati modellati allo scopo di applicare e verificare i risultati ottenuti con i semplici modelli sopracitati. Inoltre sono state svolte analisi di sensitività alla dimensione della mesh e ai parametri di smorzamento e di elasticità. I risultati hanno evidenziato una forte dipendenza dei risultati dai parametri di smorzamento, rilevando l’importanza di una corretta valutazione di questa grandezza. In ultima battuta ci si è occupati dell’accuratezza e dell’applicabilità dei modelli monodimensionali. I risultati di alcuni modelli monodimensionali realizzati con il software Quiver (Kaynia, 2009) sono stati confrontati con quelli ottenuti da modelli bidimensionali. Dal confronto è risultato un buon grado di approssimazione accompagnato da un margine di sicurezza costante. Le analisi monodimensionali sono poi state utilizzate per la verifica di sensitività. I risultati di questo lavoro sono qui presentati e accompagnati da suggerimenti qualitativi e quantitativi per la realizzazione di modelli bidimensionali affidabili. Inoltre si descrive la possibilità di utilizzare modelli monodimensionali in caso d’incertezze sui parametri. Dai risultati osservati emerge la possibilità di ottenere un risparmio di tempo nella realizzazione di importanti indagini di sensitività.

Stellar Relics of the hierarchical assembly of the Galaxy

This PhD Thesis is part of a long-term wide research project, carried out by the "Osservatorio Astronomico di Bologna (INAF-OABO)", that has as primary goal the comprehension and reconstruction of formation mechanism of galaxies and their evolution history. There is now substantial evidence, both from theoretical and observational point of view, in favor of the hypothesis that the halo of our Galaxy has been at least partially, built up by the progressive accretion of small fragments, similar in nature to the present day dwarf galaxies of the Local Group. In this context, the photometric and spectroscopic study of systems which populate the halo of our Galaxy (i.e. dwarf spheroidal galaxy, tidal streams, massive globular cluster, etc) permits to discover, not only the origin and behaviour of these systems, but also the structure of our Galactic halo, combined with its formation history. In fact, the study of the population of these objects and also of their chemical compositions, age, metallicities and velocity dispersion, permit us not only an improvement in the understanding of the mechanisms that govern the Galactic formation, but also a valid indirect test for cosmological model itself. Specifically, in this Thesis we provided a complete characterization of the tidal Stream of the Sagittarius dwarf spheroidal galaxy, that is the most striking example of the process of tidal disruption and accretion of a dwarf satellite in to our Galaxy. Using Red Clump stars, extracted from the catalogue of the Sloan Digital Sky Survey (SDSS) we obtained an estimate of the distance, the depth along the line of sight and of the number density for each detected portion of the Stream (and more in general for each detected structure along our line of sight). Moreover comparing the relative number (i.e. the ratio) of Blue Horizontal Branch stars and Red Clump stars (the two features are tracers of different age/different metallicity populations) in the main body of the galaxy and in the Stream, in order to verify the presence of an age-metallicity gradient along the Stream. We also report the detection of a population of Red Clump stars probably associated with the recently discovered Bootes III stellar system. Finally, we also present the results of a survey of radial velocities over a wide region, extending from r ~ 10' out to r ~ 80' within the massive star cluster Omega Centauri. The survey was performed with FLAMES@VLT, to study the velocity dispersion profile in the outer regions of this stellar system. All the results presented in this Thesis, have already been published in refeered journals.

I progetti di Oswald Mathias Ungers per la città di Treviri. Questioni di composizione architettonica

Abstract This PhD thesis focuses on two projects carried out by Oswald Mathias Ungers in the city of Trier. More specifi cally, this study focuses on the relationship between composition principles, architectural forms, historical context and the nature of the city where these buildings have been built. The works carried out by Ungers in Trier are unique experiences - if taken in this master’s works context - and each one of them refl ects - in its specifi c project and architectural composition theme - the results - in terms of design - of a complex research on the fundamentals of architecture carried out by Ungers in more than fi ve decades of his activity. The theoretical and compositional experiment aspect is one of the main subjects to defi ne these buildings in terms of architecture. This aspect is so crucial that it is possible to consider them as an example of radical and specifi c experiences, referred to a specifi c place and based on a specifi c theoretical corpus. More specifi cally, this study focuses on the design activity carried out by Ungers in this city, mainly between the 80s and 90s and in the fi rst decade of the 21st century. It puts forward an interpretation that does not only defi ne the essential features, elements and questions lying behind these two architectures, but fi rst and foremost analyzes the theoretical, methodological and compositional relationship between Ungers and Trier, his adopted city. An increasingly closer relationship between the architect and his city highlights the wider relationship network established between the place and the projects carried out by Ungers in this city and makes it possible to understand the importance of Trier in the work of this architect, in his education and in his way to see, think and make architecture. The projects analyzed - the Thermen am Forum Museum (1988-1996) and the Kaiserthermen entrance hall (2003-2007) - were analyzed in terms of their architectural composition in an attempt to highlight the poetry of these architectures and to fi nd out their progressive, rational - and therefore transmissible - character. This study is an attempt to assess and unveil the compositional themes characterizing these projects while detecting the compositional principles lying behind the works and verifying the design process through which such principles were translated into architecture. Looking at these works as architectural composition examples makes it possible to clarify Ungers’ hermeneutic relationship established with the city’s history and structure. More specifi cally, the main subject of this thesis is the relationship between the architect, his city and history in the architectural solutions offered by two exemplary case studies, which were both built and placed in the historical city center of Trier and both connected with the ancient core of the city. The Thermen am Forum Museum and the Kaiserthermen entrance hall projects are - though being developed at different times of Ungers’ architectural life and though being extremely different in terms of approach to their context, due to their architectural image - two works that can be compared with the historical heritage of the city and this makes them ideal examples of the relationship between architectural forms, history and environment.

Dalle ambivalenze della Storia alla “cosmopolitical fiction”: la rappresentazione dell'alterità nel romanzo di Anita Desai

Varcare le frontiere della Storia attraverso le storie personali dei suoi personaggi ha sempre affascinato la sensibilità creatrice di Anita Desai, i cui romanzi possono essere considerati un interessante esempio di letteratura di confine, che riesce nel difficile compito di misurarsi, con eleganza e sensibilità, nella rappresentazione delle più feroci forme di marginalizzazione. Proponendo un dialogo tra alterità, che apre alle complessità storico-culturali in maniera del tutto a-ideologica e imparziale, la scrittrice indoinglese procede alla “provincializzazione” dell’India attraverso le numerose ambivalenze prodotte nelle zone frontaliere analizzate. Dalla rappresentazione della frontiera identitaria esterna, ovvero dall’ambivalente rapporto intrattenuto con il colonizzatore/ex-colonizzatore inglese, alla rappresentazione della frontiera identitaria interna, ovvero l’analisi delle contraddittorie relazioni tra le componenti etniche del subcontinente, Desai arriva infine a problematizzare storie di ambivalenti processi di marginalizzazione prodotti da mondi culturali così diversi come la Germania nazista, o gli indiani Huichol del lontano Messico, tracciando geografie culturali inedite della grande ragnatela della Storia. Desai riesce così a recuperare voci liminali spesso trascurate dalla postcolonialità stessa, per riconfigurarle in un’esplorazione profonda del comune destino dell’umanità, voci straniate e stranianti che acquisiscono un vero e proprio status di agency discorsiva, proiettando la sua scrittura verso una dimensione cosmopolitica. L’opera di Desai diventa indubbiamente un’opportunità concreta per scorgere nella differenza l’universalità di una comune umanità, vale a dire un’opportunità per vedere nell’alterità un’identità ribaltata.

La drammatizzazione della storia. Uno studio del secondo Novecento attraverso i racconti del teatro di narrazione.

Sorto alla fine degli anni ottanta del Novecento, il teatro di narrazione ha raggiunto un notevole successo di pubblico a partire dagli anni Novanta. I suoi legami con il giornalismo d'inchiesta hanno condotto questo genere teatrale verso la narrazione di alcuni tra gli eventi pi controversi della storia dell'Italia repubblicana; eventi non ancora risolti sul piano processuale o al centro di una memoria storica fortemente divisa. Marco Baliani, Marco Paolini e Ascanio Celestini sono i tre autori che abbiamo scelto per affrontare un'analisi delle loro narrazioni in merito, rispettivamente, all'omicidio di Aldo Moro, alla strage di Ustica e all'eccidio delle Fosse Ardeatine. Oggetto della ricerca l'analisi dell'utilizzo delle fonti da dichiarate o comunque utilizzate dai narratori per la costruzione delle loro performances la loro selezione, la loro interpretazione e la loro disposizione nel testo e la messa in evidenza del problema della verità e del suo rapporto con il verosimile nelle narrazioni teatrali di eventi storici. Particolare attenzione viene inoltre posta al grande dibattito internazionale tra storia e fiction, alle strategie di coinvolgimento dell'opinione pubblica su temi morali e politici nonché all'analisi dei fattori economici e delle committenze che sono alla base di tali narrazioni.
