Transformación de la Doctrina de Seguridad de la OTAN, en la Post- Guerra Fría, y sus efectos en la intervención en Macedonia (2001-2003)

El objetivo de esta monografía es examinar la transformación de la doctrina de seguridad de la OTAN en la Post-Guerra Fría y sus efectos en la intervención en la República de Macedonia. La desintegración del bloque soviético implicó la variación en la definición de las amenazas que atentan contra la supervivencia de los países miembro de la Alianza Atlántica. A partir de la década de los noventa, los conflictos de naturaleza interétnica pasaron a formar parte de los riesgos que transgreden la seguridad de los Aliados y la estabilidad del área Euro-Atlántica. Por lo anterior, la OTAN intervino en aquellos Estados en los que prevalecían las confrontaciones armadas interétnicas, como por ejemplo: en Macedonia. Allí, la Alianza Atlántica ejecutó operaciones de gestión de crisis para contrarrestar la amenaza. El fenómeno a estudiar en esta investigación será analizado a partir del Realismo Subalterno y de la Teoría de la Seguridad Colectiva.

Hallazgos radiológicos de la enfermedad pulmonar en pacientes Colombianos con esclerodermia

La esclerosis sistémica (ES) es una enfermedad autoinmune multisistémica que afecta principalmente la piel, los pulmones, el tracto gastrointestinal, el corazón y los riñones. La enfermedad pulmonar, presente en casi el 100% de los casos, es el factor con mayor influencia en la mortalidad. El propósito de este estudio es realizar un análisis detallado de la enfermedad pulmonar por tomografía computarizada de alta resolución(TCAR) en pacientes Colombianos con ES, para lo cual se realizó un estudio de prevalencia analítica en 44 pacientes con ES valorados en el Hospital Universitario Mayor Méderi en los últimos 7 años. Los resultados mostraron características demográficas y clínicas similares a las previamente descritas. La prevalencia de enfermedad pulmonar intersticial fue alta, y los hallazgos de fibrosis pulmonar como vidrio esmerilado y panal de abejas se asociaron con la presencia del autoanticuerpo antiSCL70. La medida del diámetro esofágico por TCAR fue mayor en los pacientes con disfagia, antiSCL 70 y linfopenia, los cuales son marcadores de mal pronóstico.

A influência da psicologia no discurso do sentenciador: severidade "punitiva"e psicologização na justiça de menores

RESUMO: A presente dissertação, integrada no Mestrado de Psicologia Forense e da Exclusão Social, da Universidade Lusófona de Humanidades e Tecnologias, tem dois objectivos fundamentais: a análise da severidade das medidas tutelar educativas, na Justiça de Menores em Portugal e, avaliar o contributo do saber da Psicologia, no momento da decisão e escolha dessas mesmas medidas, pelo aplicador da lei. Para isso, foram analisados 58 Processos Tutelares Educativos, presentes no Tribunal de Família e Menores de Lisboa, e 11 arquivados na Direcção Geral de Reinserção Social, incidindo a análise, sobretudo, no tipo de medidas aplicadas, o género de crimes cometidos, e a referência a avaliações psicológicas ou perícias sobre a personalidade, como fundamento da decisão. Estes processos são analisados à luz de um instrumento de medida da aplicação de medidas tutelares em jovens, com idades compreendidas entre os 12 e os 16 anos: o Índice de Severidade Penalizadora e Psicologização no âmbito da transgressionalidade e delinquência juvenil (Criminalização Secundária – IPSS-CS-TDJ), de 2011. Os resultados evidenciam índices médios de severidade punitiva e de psicologização. Este estudo, dado o seu carácter pioneiro, representa, uma tentativa de abordagem empírica do problema. Para futuras investigações propõe-se a aplicação do instrumento a processos judiciais de outras regiões do país. ABSTRACT: The present thesis, integrated into Forensic Psychology and Social Exclusion Masters Degree, of Lusophone University of Humanities and Technologies, has two fundamental objectives: an analysis of the tutelary educative measures severity, in juvenile justice system, in Portugal, and evaluate the contribution of the knowledge of psychology, at the moment of decision and choice of those measures, by judge. For this, were analyse 58 tutelary educative processes, belonging to the Family and Juvenile Court of Lisbon, and 11 archived in General Direction of Social Reintegration, focusing, mainly, on the type of measures applied, kind of crimes, and reference to psychological evaluations or personality investigation, as foundation of judicial decision. These processes are analysed based on an instrument to measure the application of punitive measure to young people: Punishment Severity Index and Psychologisation in the framework of Infringement and Juvenile Delinquency (ISPP-CSTDJ), 2011. The results show an average level of punishment severity and psychologisation. This study, represents a pioneer empirically approach to the problem. In order to future investigations is proposed apply the instrument to processes from other regions of the country.

As atitudes dos professores face à inclusão de alunos com deficiência : o contacto com a deficiência

RESUMO: Actualmente as práticas de exclusão evoluíram para uma perspectiva de inclusão, assim como para a consciencialização dos direitos e deveres de cada um, como forma de dar resposta à sociedade heterogénea existente. A visão baseada nos sistemas de identificação e classificação dos sujeitos em várias categorias de deficiências era algo muito usual, mas que foi abolida, dando assim lugar ao conceito de Necessidades Educativas Especiais, com uma óptica mais abrangente, tendo em conta o contexto em que o sujeito está envolvido (Nunes, 2000). As atitudes dos professores face aos alunos com deficiência têm melhorado significativamente (Ribeiro, 1999), no entanto o processo de inclusão destas crianças no ensino regular não está isento de problemas. Neste sentido, e para que este desafio seja ultrapassado com sucesso, torna-se essencial que os professores modifiquem as suas atitudes e passem a desempenhar um papel mais activo nas suas funções, devendo para isso, começar por adaptar o currículo, e posteriormente repensar as suas estratégias e métodos de trabalho, como forma a responder às necessidades de todos os alunos (Ainscow, 1997). O objectivo principal deste estudo é verificar se o contacto com a deficiência (a nível da experiência no ensino, formação inicial e contacto na infância/juventude), por parte dos professores, influencia as suas atitudes em relação à formação necessária para a inclusão de alunos com deficiência, bem como às vantagens que esta representa para esses mesmos alunos. A amostra foi constituída por 672 professores do ensino regular, todos estão actualmente no activo e leccionam níveis de ensino do Pré-Escolar ao Ensino Secundário, de Norte a Sul do país. (N = 482 do género feminino e N =190 do género masculino). O instrumento de avaliação aplicado foi o questionário APIAD – Atitude dos Professores face à Inclusão de Alunos com Deficiência (Leitão, 2011). Concluiu-se que a experiência no ensino de alunos com deficiência influencia significativamente a atitude dos professores face à formação necessária (deficiência motora: p<0,001; deficiência auditiva: p<0,001; deficiência visual: p<0,001; deficiência mental: p=0,004) e face às vantagens da inclusão para os alunos com deficiência (deficiência motora: p=0,005; deficiência auditiva: p<0,001; deficiência visual: p<0,001; deficiência mental: p=0,022). No que se refere ao contacto com pessoas com deficiência durante a formação inicial, concluiu-se que existem diferenças significativas na atitude dos professores face às vantagens da inclusão para os alunos com deficiência (deficiência motora: p<0,001; deficiência auditiva: p<0,001; deficiência visual: p<0,001; deficiência mental: p<0,001). No entanto, no que respeita à formação, a atitude dos professores não difere, independentemente de terem tido esse contacto (deficiência motora: p=0,393; deficiência auditiva: p=0,456; deficiência visual: p=0,055; deficiência mental: p=0,342). Relativamente ao contacto com pessoas com deficiência durante a infância/juventude conclui-se que não existem diferenças na atitude dos professores em relação à formação necessária (deficiência motora: p=0,893; deficiência auditiva: p=0,667; deficiência visual: p=0,459; deficiência mental: p=0,918). Por sua vez, no que respeita às vantagens da inclusão para os alunos com deficiência, esta variável só influencia significativamente a atitude dos professores no caso da deficiência visual (deficiência motora: p=0,154; deficiência auditiva: p=0,100; deficiência visual: p=0,045; deficiência mental: p=0,149). ABSTRACT: Currently the exclusionary practices evolved to an inclusion perspective, as well as the awareness of rights and duties of each one as a way to reply to the existing heterogeneous society. The vision-based systems for identification and classification of subjects into various categories of disabilities was very unusual, but it was abolished, giving way to the concept of Special Educational Needs, with a broader perspective, considering the context in which the subject is involved (Nunes, 2000). The teachers attitude face to the students with disabilities have improved significantly (Ribeiro, 1999), however the process of inclusion of these children in regular education isn't exempt of problems. In this direction and so this challenge is exceeded successfully, it is essential that teachers change their attitudes and start to perform a more active role in their functions, and to do so, start by adapting the curriculum and then rethink their strategies and working methods, in order to meet the needs of all students (Ainscow, 1997). The main purpose of this study is to verify that the contact with the disability (educational level of experience, initial formation and contact in childhood/youth), among teachers, influences their attitudes towards the needed formation for the inclusion of students with disabilities as well as the benefits that this represents for them. The sample consisted by 672 regular educational teachers, all currently in employment and teaching from Preschool to High school, from North to South. (N = 482 females and N = 190 males). The evaluation instrument used was the survey APIAD - Teachers attitude towards the inclusion of students with disabilities (Leitão, 2011). It was concluded that the experience in teaching students with disabilities influences significantly the teachers attitude faced to the necessary formation (motor disability: p<0,001; hearing impairment: p<0,001; visual impairment: p<0,001; mental disability: p=0,004) and faced to the inclusion benefits for students with disabilities (motor disability: p=0,005; hearing impairment: p<0,001; visual impairment: p<0,001; mental disability: p=0,022).Concerning to the contact with people with disabilities during the initial formation, it was concluded that there are significant differences in the teachers attitude face to the inclusion benefits for students with disabilities (motor disability: p<0,001; hearing impairment: p<0,001; visual impairment: p<0,001; mental disability: p<0,001). In relation to the formation, the teachers attitude is the same, regardless of whether or not they have had such contact (motor disability: p=0,393; hearing impairment: p=0,456; visual impairment: p=0,055; mental disability: p=0,342). Regarding to the contact with people with disabilities during childhood/youth, it was concluded that there is no difference in the teachers attitude in relation to the formation needed (motor disability: p=0,893; hearing impairment: p=0,667; visual impairment: p=0,459; mental disability: p=0,918). On the other way, regarding to the inclusion benefits for students with disabilities, this influences significantly the teachers attitude just in the visual impairment. (motor disability: p=0,154; hearing impairment: p=0,100; visual impairment: p=0,045; mental disability: p=0,149).

Reabilitação de edifícios habitacionais com valor patrimonial : o caso do centro histórico de Guimarães

A presente dissertação centra-se no tema “reabilitação de edifícios habitacionais com valor patrimonial – o caso do centro histórico de Guimarães“ Com o passar dos anos tem-se feito, cada vez mais, um esforço para tentar combater as áreas degradadas das cidades e colmatar lacunas referentes às ações tomadas nesse sentido. É necessária a intervenção dos Arquitetos que, através dos seus conhecimentos e poderes, têm a obrigação de manter a história da Arquitetura intacta no tempo. Esta dissertação centra-se em analisar algumas questões inerentes ligadas á reabilitação de edifícios habitacionais, declarando possíveis respostas. As questões vão desde perceber como é que um espaço reabilitado pode ser tão adequado como um espaço pensado de raiz até à questão da utilização de materiais, passando pelo tipo de relacionamento entre o arquiteto e o proprietário, e como os dois protagonistas podem fazer valer as suas ideias em simultâneo. Este trabalho pretende, então, transmitir a importância da reabilitação e preservação dos centros históricos, mostrando que com a reabilitação é possível a sua conservação. Para uma melhor compreensão do tema selecionado, Guimarães apresenta-se como uma cidade que vai ao encontro de todos os pontos referidos até este momento, sendo o seu centro histórico um exemplo de requalificação e conseguindo, com uma metodologia bem determinada, manter todas as origens da cidade, no qual são utilizadas técnicas e materiais tradicionais de construção. A dissertação termina com a análise de cada projeto escolhido para estudo.

Assim, constatou-se que suas tendências atuais vão em direção de buscar a vinculação prática entre o que ocorre na sala de aula e fora dela.

The counter-propagating Rossby-wave perspective on baroclinic instability. Part IV: Nonlinear life cycles

Pairs of counter-propagating Rossby waves (CRWs) can be used to describe baroclinic instability in linearized primitive-equation dynamics, employing simple propagation and interaction mechanisms at only two locations in the meridional plane—the CRW ‘home-bases’. Here, it is shown how some CRW properties are remarkably robust as a growing baroclinic wave develops nonlinearly. For example, the phase difference between upper-level and lower-level waves in potential-vorticity contours, defined initially at the home-bases of the CRWs, remains almost constant throughout baroclinic wave life cycles, despite the occurrence of frontogenesis and Rossby-wave breaking. As the lower wave saturates nonlinearly the whole baroclinic wave changes phase speed from that of the normal mode to that of the self-induced phase speed of the upper CRW. On zonal jets without surface meridional shear, this must always act to slow the baroclinic wave. The direction of wave breaking when a basic state has surface meridional shear can be anticipated because the displacement structures of CRWs tend to be coherent along surfaces of constant basic-state angular velocity, U. This results in up-gradient horizontal momentum fluxes for baroclinically growing disturbances. The momentum flux acts to shift the jet meridionally in the direction of the increasing surface U, so that the upper CRW breaks in the same direction as occurred at low levels

Using TerraSAR-X data for improved urban flood model validation.

Urban flood inundation models require considerable data for their parameterisation, calibration and validation. TerraSAR-X should be suitable for urban flood detection because of its high resolution in stripmap/spotlight modes. The paper describes ongoing work on a project to assess how well TerraSAR-X can detect flooded regions in urban areas, and how well these can constrain the parameters of an urban flood model. The study uses a TerraSAR-X image of a 1-in-150 year flood near Tewkesbury, UK , in 2007, for which contemporaneous aerial photography exists for validation. The DLR SETES SAR simulator was used in conjunction with LiDAR data to estimate regions of the image in which water would not be visible due to shadow or layover caused by buildings and vegetation. An algorithm for the delineation of flood water in urban areas is described, together with its validation using the aerial photographs.

The PML for rough surface scattering

In this paper we investigate the use of the perfectly matched layer (PML) to truncate a time harmonic rough surface scattering problem in the direction away from the scatterer. We prove existence and uniqueness of the solution of the truncated problem as well as an error estimate depending on the thickness and composition of the layer. This global error estimate predicts a linear rate of convergence (under some conditions on the relative size of the real and imaginary parts of the PML function) rather than the usual exponential rate. We then consider scattering by a half-space and show that the solution of the PML truncated problem converges globally at most quadratically (up to logarithmic factors), providing support for our general theory. However we also prove exponential convergence on compact subsets. We continue by proposing an iterative correction method for the PML truncated problem and, using our estimate for the PML approximation, prove convergence of this method. Finally we provide some numerical results in 2D.(C) 2008 IMACS. Published by Elsevier B.V. All rights reserved.

Modelling monsoons: understanding and predicting current and future behaviour

The global monsoon system is so varied and complex that understanding and predicting its diverse behaviour remains a challenge that will occupy modellers for many years to come. Despite the difficult task ahead, an improved monsoon modelling capability has been realized through the inclusion of more detailed physics of the climate system and higher resolution in our numerical models. Perhaps the most crucial improvement to date has been the development of coupled ocean-atmosphere models. From subseasonal to interdecadal time scales, only through the inclusion of air-sea interaction can the proper phasing and teleconnections of convection be attained with respect to sea surface temperature variations. Even then, the response to slow variations in remote forcings (e.g., El Niño—Southern Oscillation) does not result in a robust solution, as there are a host of competing modes of variability that must be represented, including those that appear to be chaotic. Understanding the links between monsoons and land surface processes is not as mature as that explored regarding air-sea interactions. A land surface forcing signal appears to dominate the onset of wet season rainfall over the North American monsoon region, though the relative role of ocean versus land forcing remains a topic of investigation in all the monsoon systems. Also, improved forecasts have been made during periods in which additional sounding observations are available for data assimilation. Thus, there is untapped predictability that can only be attained through the development of a more comprehensive observing system for all monsoon regions. Additionally, improved parameterizations - for example, of convection, cloud, radiation, and boundary layer schemes as well as land surface processes - are essential to realize the full potential of monsoon predictability. A more comprehensive assessment is needed of the impact of black carbon aerosols, which may modulate that of other anthropogenic greenhouse gases. Dynamical considerations require ever increased horizontal resolution (probably to 0.5 degree or higher) in order to resolve many monsoon features including, but not limited to, the Mei-Yu/Baiu sudden onset and withdrawal, low-level jet orientation and variability, and orographic forced rainfall. Under anthropogenic climate change many competing factors complicate making robust projections of monsoon changes. Absent aerosol effects, increased land-sea temperature contrast suggests strengthened monsoon circulation due to climate change. However, increased aerosol emissions will reflect more solar radiation back to space, which may temper or even reduce the strength of monsoon circulations compared to the present day. Precipitation may behave independently from the circulation under warming conditions in which an increased atmospheric moisture loading, based purely on thermodynamic considerations, could result in increased monsoon rainfall under climate change. The challenge to improve model parameterizations and include more complex processes and feedbacks pushes computing resources to their limit, thus requiring continuous upgrades of computational infrastructure to ensure progress in understanding and predicting current and future behaviour of monsoons.

Cross-modal preference acquisition: evaluative conditioning of pictures by affective olfactory and auditory cues

In this research, a cross-model paradigm was chosen to test the hypothesis that affective olfactory and auditory cues paired with neutral visual stimuli bearing no resemblance or logical connection to the affective cues can evoke preference shifts in those stimuli. Neutral visual stimuli of abstract paintings were presented simultaneously with liked and disliked odours and sounds, with neutral-neutral pairings serving as controls. The results confirm previous findings that the affective evaluation of previously neutral visual stimuli shifts in the direction of contingently presented affective auditory stimuli. In addition, this research shows the presence of conditioning with affective odours having no logical connection with the pictures.

The simulation of peak and delayed ENSO teleconnections

There is much evidence that El Niño and La Niña lead to significant atmospheric seasonal predictability across much of the globe. However, despite successful predictions of tropical Pacific SSTs, atmospheric seasonal forecasts have had limited success. This study investigates model errors in the Hadley Centre Atmospheric Model version 3 (HadAM3) by analyzing composites of similar El Niño and La Niña events at their peak in December–January–February (DJF) and through their decay in March–April–May (MAM). The large-scale, tropical ENSO teleconnections are modeled accurately by HadAM3 during DJF but the strongest extratropical teleconnection, that in the North Pacific during winter, is modeled inaccurately. The Aleutian low is frequently observed to shift eastward during El Niño but the modeled response always consists of a deepening of the low without a shift. This is traced to small errors in the sensitivity of precipitation to SST in the tropical Pacific, which does not display enough variability so that the precipitation is always too high over the warmest SSTs. This error is reduced when vertical resolution is increased from 19 to 30 levels but enhanced horizontal resolution does not improve the simulation further. In MAM, following the peak of an El Niño or La Niña, atmospheric anomalies are observed to decay rapidly. The modeled ENSO response in DJF persists into MAM, making the extratropical anomalies in MAM too strong. This inaccuracy is again likely to be due to the high modeled sensitivity of tropical Pacific precipitation to SST, which is not significantly improved with enhanced vertical or horizontal resolution in MAM.

Boundary layer structure and decoupling from synoptic scale flow during NAMBLEX

This paper presents an overview of the meteorology and planetary boundary layer structure observed during the NAMBLEX field campaign to aid interpretation of the chemical and aerosol measurements. The campaign has been separated into five periods corresponding to the prevailing synoptic condition. Comparisons between meteorological measurements ( UHF wind profiler, Doppler sodar, sonic aneometers mounted on a tower at varying heights and a standard anemometer) and the ECMWF analysis at 10 m and 1100 m identified days when the internal boundary layer was decoupled from the synoptic flow aloft. Generally the agreement was remarkably good apart from during period one and on a few days during period four when the diurnal swing in wind direction implies a sea/land breeze circulation near the surface. During these periods the origin of air sampled at Mace Head would not be accurately represented by back trajectories following the winds resolved in ECMWF analyses. The wind profiler observations give a detailed record of boundary layer structure including an indication of its depth, average wind speed and direction. Turbulence statistics have been used to assess the height to which the developing internal boundary layer, caused by the increased surface drag at the coast, reaches the sampling location under a wide range of marine conditions. Sampling conducted below 10 m will be impacted by emission sources at the shoreline in all wind directions and tidal conditions, whereas sampling above 15 m is unlikely to be affected in any of the wind directions and tidal heights sampled during the experiment.

Extraction of tidal channel networks from airborne scanning laser altimetry and aerial photography

The study of the morphodynamics of tidal channel networks is important because of their role in tidal propagation and the evolution of salt-marshes and tidal flats. Channel dimensions range from tens of metres wide and metres deep near the low water mark to only 20-30cm wide and 20cm deep for the smallest channels on the marshes. The conventional method of measuring the networks is cumbersome, involving manual digitising of aerial photographs. This paper describes a semi-automatic knowledge-based network extraction method that is being implemented to work using airborne scanning laser altimetry (and later aerial photography). The channels exhibit a width variation of several orders of magnitude, making an approach based on multi-scale line detection difficult. The processing therefore uses multi-scale edge detection to detect channel edges, then associates adjacent anti-parallel edges together to form channels using a distance-with-destination transform. Breaks in the networks are repaired by extending channel ends in the direction of their ends to join with nearby channels, using domain knowledge that flow paths should proceed downhill and that any network fragment should be joined to a nearby fragment so as to connect eventually to the open sea.

Top-down solar modulation of climate: evidence for centennial-scale change

During the descent into the recent ‘exceptionally’ low solar minimum, observations have revealed a larger change in solar UV emissions than seen at the same phase of previous solar cycles. This is particularly true at wavelengths responsible for stratospheric ozone production and heating. This implies that ‘top-down’ solar modulation could be a larger factor in long-term tropospheric change than previously believed, many climate models allowing only for the ‘bottom-up’ effect of the less-variable visible and infrared solar emissions. We present evidence for long-term drift in solar UV irradiance, which is not found in its commonly used proxies. In addition, we find that both stratospheric and tropospheric winds and temperatures show stronger regional variations with those solar indices that do show long-term trends. A top-down climate effect that shows long-term drift (and may also be out of phase with the bottom-up solar forcing) would change the spatial response patterns and would mean that climate-chemistry models that have sufficient resolution in the stratosphere would become very important for making accurate regional/seasonal climate predictions. Our results also provide a potential explanation of persistent palaeoclimate results showing solar influence on regional or local climate indicators.
