Rearrangement of the urban space in the sector of Saint Victorino and Saint Ines (Bogota) in relation with the dynamics of informality and marginality (1948-2010)

The present article analyze the urban transformations happened in the sector of Saint Victorino and Saint Ines in the city of Bogota D.C. between 1948 and 2010, making use of the "Genealogical Methodology" during the process of inquiry that allow to contrast the visions that are usually accepted of "progress" and "urban renovation" in the urban market context by the existence of a informal economic and a population in conditions of marginality that configures a good part of the "popular urban culture" of the Bogota in the 20th and 21st century. This vision permit to observe from various perspectives the changes that happened in this sector of the city, the impacts of the history facts occurred en this time period and, in special, the real effects of a rearrangement urban process that began in 1998 and has been prolonged to date, which has left a significant mark about the urban and social physiognomy of the place.

A new efficient approach to the direct restricted active space self-consistent field method

An implicitly parallel method for integral-block driven restricted active space self-consistent field (RASSCF) algorithms is presented. The approach is based on a model space representation of the RAS active orbitals with an efficient expansion of the model subspaces. The applicability of the method is demonstrated with a RASSCF investigation of the first two excited states of indole

Automatic generation of active coordinates for quantum dynamics calculations: application to the dynamics of benzene photochemistry

A new practical method to generate a subspace of active coordinates for quantum dynamics calculations is presented. These reduced coordinates are obtained as the normal modes of an analytical quadratic representation of the energy difference between excited and ground states within the complete active space self-consistent field method. At the Franck-Condon point, the largest negative eigenvalues of this Hessian correspond to the photoactive modes: those that reduce the energy difference and lead to the conical intersection; eigenvalues close to 0 correspond to bath modes, while modes with large positive eigenvalues are photoinactive vibrations, which increase the energy difference. The efficacy of quantum dynamics run in the subspace of the photoactive modes is illustrated with the photochemistry of benzene, where theoretical simulations are designed to assist optimal control experiments

The undergraduate level (1st study cycle) as a fundamental platform/ standard for the development of Urban and Regional Planning in higher education programs

The ongoing reforms, which were introduced under the Bologna Process and have already been extended outside of Europe , are a unique opportunity for reinforcing and structuring a common platform of understanding among members, based on the full time undergraduate courses in ( Urbanismo) Urban and Regional Planning. The training programs at this 1st cycle level, will obviously continue with the 2nd and 3rd cycles (Bachelor's Degree, Master's Degree and PhD Degree or 3+2+3 years). The training programs at this full time 1st cycle level, can also becomes the framework of understanding for the development of research in the urban fields at national and international levels.

Os sentimentos de competência dos docentes de Educação Física e a sua percepção sobre a organização da aprendizagem na sala de aula

Os Professores assumem um papel determinante nas aprendizagens dos alunos, que está fortemente ligada ao sentimento de competência que os mesmos têm. O objectivo deste estudo é investigar se o sentimento de competência dos Professores de Educação Física se relaciona ou não com: a aprendizagem cooperativa, as relações entre o professor e o aluno, a negociação e o ensino cooperativo. A amostra foi constituída por cento e quinze Professores de Educação Física do ensino regular (N=46 Género Feminino e N=69 Género Masculino), dos quais setenta e oito leccionam o 2º e 3ºciclo e trinta e sete o ensino Secundário. Quanto aos instrumentos de recolha de informação foram utilizados dois inquéritos por questionário denominados por: A PERCEPÇÃO DOS PROFESSORES SOBRE A APRENDIZAGEM NA SALA DE AULA (A.S.A. – E.P.A., Leitão, 2012) e a ESCALA DE AUTO-ESTIMA PROFISSIONAL (E.A.P., Leitão, 2012). Neste estudo é possível verificar que os Docentes de Educação Física sentem-se mais competentes e capazes quando percepcionam na sala de aula um ambiente mais cooperativo. A relação professor-aluno é significativa visto que o Professor sente-se mais capaz e competente quando tem uma melhor ligação com os alunos, tal como nos refere Jesus (1996) que considera que um Docente motivado e realizado tende a ter alunos também motivados e activos. No que se refere à Negociação, esta não é sentida pelos Docentes como um factor que influencie o seu sentimento e a capacidade de competência. Por último, no que diz respeito ao ensino cooperativo, os professores sentem-se mais competentes e capazes quando partilham com os colegas várias estratégias de ensino ou feedbacks, mostrando ser importante, na aquisição de competências e capacidade, a ligação com outros profissionais de ensino.

Infância perdida : o retrato do trabalho infantil no Paraná e os reflexos na Educação no final do século XX (década de 1990)

Este estudo pretende refletir acerca do trabalho infantil à luz das condições propostas de erradicação dessa modalidade no Estado do Paraná. Utilizando como fonte de pesquisa a imprensa diária e documentos oficiais da década de 1990 do século XX, buscou-se analisar as matérias estampadas nos jornais do referido Estado que faziam parte do acervo da Casa da Memória e Biblioteca Pública do Paraná, aproximando-os com os dados oficiais apresentados nos mapas de indicativos do trabalho infanto-juvenil, a fim de apontar a realidade em que estes pequenos trabalhadores estavam envolvidos. A referente investigação ressalta a importância do trabalho infantil na construção da história social e da educação, procurando demonstrar os motivos pelos quais crianças faziam parte da população economicamente ativa da época, bem como as consequências que esse tipo de trabalho traz à infância e seus reflexos no sistema educacional e social paranaense.

СЛІДИ КОНФЛІКТУ – ПОЛІТИЧНІ В’ЯЗНІ У ПРОЗІ ЗОФІЇ НАЛКОВСЬКОЇ

The main aim of the article is highlighting subplots present in the prose works of Nałkowska which are devoted to Ukrainian and Belarusian political prisoners. The author maintains that the Polish colonizing activity along the so-called ‘Eastern Borderland’ requires a detailed and comprehensive study. The results of this analys is should then be compared against contemporary Ukrainian literature as well as the history of the national liberation and nationalist movements at the beginning of 20th century. The article explores three prose texts by Nałkowska, that is, “Węzły życia” (The Bonds of Life), “Niedobra miłość” (Bad Love) and “Ściany świata” (The Walls of the World). The subplots present in all three works can be analyzed in terms of inevident, yet indelible traces pertaining to ethnic conflicts between Poles, Ukrainians and Belarusians, as well as the Jewish pogroms. The themes that span the above- mentioned text can be outlined as follows: first of all, the radical metamorphosis of political attitudes on the part of the protagonists representing former Legionists; secondly, the heroines’ active work for the benefit of the prisoners, also the political ones. In spite of censorship and visibly more and more extreme politics of the authoritarian state towards ethnic minorities, Nałkowska remained one of the few writers who managed to deliver the arrested history of persecutions. Keywords: politics of colonization, national minority, traces of conflict, political prisoners

An Integrated Assessment of changes in the thermohaline circulation

This paper discusses the risks of a shutdown of the thermohaline circulation (THC) for the climate system, for ecosystems in and around the North Atlantic as well as for fisheries and agriculture by way of an Integrated Assessment. The climate model simulations are based on greenhouse gas scenarios for the 21st century and beyond. A shutdown of the THC, complete by 2150, is triggered if increased freshwater input from inland ice melt or enhanced runoff is assumed. The shutdown retards the greenhouse gas-induced atmospheric warming trend in the Northern Hemisphere, but does not lead to a persistent net cooling. Due to the simulated THC shutdown the sea level at the North Atlantic shores rises by up to 80 cm by 2150, in addition to the global sea level rise. This could potentially be a serious impact that requires expensive coastal protection measures. A reduction of marine net primary productivity is associated with the impacts of warming rather than a THC shutdown. Regional shifts in the currents in the Nordic Seas could strongly deteriorate survival chances for cod larvae and juveniles. This could lead to cod fisheries becoming unprofitable by the end of the 21st century. While regional socioeconomic impacts might be large, damages would be probably small in relation to the respective gross national products. Terrestrial ecosystem productivity is affected much more by the fertilization from the increasing CO2 concentration than by a THC shutdown. In addition, the level of warming in the 22nd to 24th century favours crop production in northern Europe a lot, no matter whether the THC shuts down or not. CO2 emissions corridors aimed at limiting the risk of a THC breakdown to 10% or less are narrow, requiring departure from business-as-usual in the next few decades. The uncertainty about THC risks is still high. This is seen in model analyses as well as in the experts’ views that were elicited. The overview of results presented here is the outcome of the Integrated Assessment project INTEGRATION.

Soil geochemical analyses as an indication of metal working at the excavation of a house in the Roman City at Silchester (UK)

Silchester is the site of a major late Iron Age and Roman town (Calleva Atrebatum), situated in northern Hampshire (England (UK)) and occupied between the late first century BC and the fifth or sixth century AD. Extensive evidence of the nature of the buildings and the plan of the town was obtained from excavations undertaken between 1890 and 1909. The purpose of this study was to use soil geochemical analyses to reinforce the archaeological evidence particularly with reference to potential metal working at the site. Soil analysis has been used previously to distinguish different functions or land use activity over a site and to aid identification and interpretation of settlement features (Entwistle et al., 2000). Samples were taken from two areas of the excavation on a 1-metre grid. Firstly from an area of some 500 square metres from contexts of late first/early second century AD date throughout the entirety of a large 'town house' (House 1) from which there was prima facie evidence of metalworking.

The sea-level conundrum: case studies from palaeo-archives

Uncertainties in sea-level projections for the 21st century have focused ice sheet modelling efforts to include the processes that are thought to be contributing to the recently observed rapid changes at ice sheet margins. This effort is still in its infancy, however, leaving us unable to make reliable predictions of ice sheet responses to a warming climate if such glacier accelerations were to increase in size and frequency. The geological record, however, has long identified examples of nonlinear ice sheet response to climate forcing (Shackleton NJ, Opdyke ND. 1973. Oxygen isotope and paleomagnetic stratigraphy of equatorial Pacific core V28–239, late Pliocene to latest Pleistocene. Geological Society of America Memoirs145: 449–464; Fairbanks RG. 1989. A 17,000 year glacio-eustatic sea level record: influence of glacial melting rates on the Younger Dryas event and deep ocean circulation. Nature342: 637–642; Bard E, Hamelin B, Arnold M, Montaggioni L, Cabioch G, Faure G, Rougerie F. 1996. Sea level record from Tahiti corals and the timing of deglacial meltwater discharge. Nature382: 241–244), thus suggesting an alternative strategy for constraining the rate and magnitude of sea-level change that we might expect by the end of this century.

Proceedings of the Rank Forum on Vitamin D

The Rank Forum on Vitamin D was held on 2nd and 3rd July 2009 at the University of Surrey, Guildford, UK. The workshop consisted of a series of scene-setting presentations to address the current issues and challenges concerning vitamin D and health, and included an open discussion focusing on the identification of the concentrations of serum 25-hydroxyvitamin D (25(OH)D) (a marker of vitamin D status) that may be regarded as optimal, and the implications this process may have in the setting of future dietary reference values for vitamin D in the UK. The Forum was in agreement with the fact that it is desirable for all of the population to have a serum 25(OH)D concentration above 25 nmol/l, but it discussed some uncertainty about the strength of evidence for the need to aim for substantially higher concentrations (25(OH)D concentrations . 75 nmol/l). Any discussion of ‘optimal’ concentration of serum 25(OH)D needs to define ‘optimal’ with care since it is important to consider the normal distribution of requirements and the vitamin D needs for a wide range of outcomes. Current UK reference values concentrate on the requirements of particular subgroups of the population; this differs from the approaches used in other European countries where a wider range of age groups tend to be covered. With the re-emergence of rickets and the public health burden of low vitamin D status being already apparent, there is a need for urgent action from policy makers and risk managers. The Forum highlighted concerns regarding the failure of implementation of existing strategies in the UK for achieving current vitamin D recommendations.
