O depoimento da criança no processo civil e sua valoração probatória

O presente trabalho tem por objetivo examinar um dos meios de prova oral do processo civil, que é o depoimento da criança. Diante da existência de uma certa resistência quanto à utilização e validade deste meio de prova, foram destacados argumentos de direito probatório favoráveis à tomada do depoimento infantil, como o direito à prova no sistema da prova livre e na vertente do direito de ação e defesa, além da necessária comparação com o processo penal e o destaque aos princípios da proteção integral e do superior interesse da criança, os quais foram reforçados por outros de natureza médico-psicológica, que visaram a destacar a capacidade cognitiva da criança em recordar fatos e relatá-los. Após a desconstrução do modelo de exclusão prévia do depoimento infantil, a dissertação abordou os modelos de proteção para a audição judicial da criança, para se evitar a vitimização secundária da criança e exposição desnecessária às partes, advogados e juízes. Neste particular, foram revisados os modelos inglês do closed-circuit television - CCTV e argentino da Câmara de Gesell como paradigmas para vários outros países, inclusive o Brasil que tem incentivado o depoimento sem dano. Em derradeiro, foi examinada a valoração desse depoimento da criança, tomando-se por base a justificação lógico-racional da prova consubstanciada nos módulos de constatação, ocasião em que foi possível sublinhar que a utilização dos modelos e métodos de inquirição protetivos culminam em maior credibilidade ao depoimento da criança no processo civil e proporcionam a descoberta de falsidade voluntária ou não. Também no tópico da valoração da prova, o conteúdo do depoimento infantil vai trazer maior confiança quando conjugado com elementos intrínsecos, como a coerência do discurso e a ausência de contradições, e extrínsecos, realizado na modalidade protetiva.

Societal metabolism of societies: the bifurcation between Spain and Ecuador

This paper presents an application of the Multiple-Scale Integrated Assessment of Societal Metabolism to the recent economic history of Ecuador and Spain. Understanding the relationship between the Gross Domestic Product (GDP) and the throughput of matter and energy over time in modern societies is crucial for understanding the sustainability predicament as it is linked to economic growth. When considering the dynamics of economic development, Spain was able to take a different path than Ecuador thanks to the different characteristics of its energy budget and other key variables. This and other changes are described using economic and biophysical variables (both extensive and intensive referring to different hierarchical levels). The representation of these parallel changes (on different levels and describable only using different variables) can be kept in coherence by adopting the frame provided by MSIASM.

Characterisation of neutron spectra in mixed high energy fields in lineal accelerators: response functions validation

Actualment, la resposta de la majoria d’instrumentació operacional i dels dosímetres personals utilitzats en radioprotecció per a la dosimetria neutrònica és altament dependent de l’energia dels espectres neutrònics a analitzar, especialment amb camps neutrònics amb una important component intermitja. En conseqüència, la interpretació de les lectures d’aquests aparells es complicada si no es té un coneixement previ de la distribució espectral de la fluència neutrònica en els punts d’interès. El Grup de Física de les Radiacions de la Universitat Autònoma de Barcelona (GFR-UAB) ha desenvolupat en els últims anys un espectròmetre de neutrons basat en un Sistema d’Esferes Bonner (BSS) amb un contador proporcional d’3He com a detector actiu. Els principals avantatges dels espectròmetres de neutrons per BSS són: la seva resposta isotròpica, la possibilitat de discriminar la component neutrònica de la gamma en camps mixtos, i la seva alta sensibilitat neutrònica als nivells de dosi analitzats. Amb aquestes característiques, els espectròmetres neutrònics per BSS compleixen amb els estándards de les últimes recomanacions de la ICRP i poden ser utilitzats també en el camp de la dosimetria neutrònica per a la mesura de dosis en el rang d’energia que va dels tèrmics fins als 20 MeV, en nou ordres de magnitud. En el marc de la col•laboració entre el GFR - UAB i el Laboratorio Nazionale di Frascati – Istituto Nazionale di Fisica Nucleare (LNF-INFN), ha tingut lloc una experiència comparativa d’espectrometria per BSS amb els feixos quasi monoenergètics de 2.5 MeV i 14 MeV del Fast Neutron Generator de l’ENEA. En l’exercici s’ha determinat l’espectre neutrònic a diferents distàncies del blanc de l’accelerador, aprofitant el codi FRUIT recentment desenvolupat pel grup LNF. Els resultats obtinguts mostren una bona coherència entre els dos espectròmetres i les dades mesurades i simulades.

Programa vellesa, activitat física i dependència (Vafid): justificació i bases per a la sistematització

El present estudi es centra en els programes d’activitat física adreçats a persones grans en situació de dependència, que es esenvolupen en grup i que utilitzen el moviment actiu com a principal eina de treball. Es tracta d’una recerca que, per una banda, estudia i analitza les bases teòriques que avalen la importància i la necessitat de l’aplicació d’aquest tipus de programes. Per l’altra, justifica i defineix, amb detall, les línies directrius que han de guiar el seu desenvolupament i la seva aplicació en l’àmbit d’institucions d’atenció a les persones grans (residències, centres de dia i centres sòciosanitaris). El marc conceptual (capítol II) es construeix a partir d’una àmplia recerca bibliogràfica sobre les quatre dimensions d’anàlisi clau (l’envelliment, la dependència, l’atenció a les persones grans i l’activitat física) que fonamenta i justifica la proposta de programa que es fa en la segona part (capítol III). En aquesta es defineixen els referents, les finalitats, els objectius, els recursos que es poden utilitzar, les indicacions bàsiques per a organitzar el treball, els aspectes metodològics essencials per a l’aplicació del programa i les condicions necessàries per a poder-lo implementar. El resultat de tot el procés de recerca i estudi permet dir que, a nivell teòric, l’activitat física és una eina útil, eficaç i amb moltes possibilitats cara a l’atenció a les persones grans en situació de dependència. Que els esmentats programes han de ser fruit d’un procés de planificació, han de considerar les diferents dimensions de l’ésser en interacció constant, han de ser aplicats donant més importància al procés que al producte i que els recursos disponibles s’han d’utilitzar d’acord amb aquests plantejaments. En les línies de futur per a aquesta recerca, es planteja la seva continuació a partir de l’aplicació del programa VAFiD en diferents grups i la seva avaluació (seguint el model d’avaluació responent de Robert Stake) per determinar-ne la coherència i la qualitat.

Retinal pigment epithelium tears after intravitreal injection of ranibizumab for predominantly classic neovascular membranes secondary to age-related macular degeneration.

PURPOSE: Retinal pigment epithelium (RPE) tear is an extremely rare complication in patients with classic neovascular membranes without RPE detachment. We evaluate their incidence and functional outcome following treatment with intravitreal ranibizumab. METHODS: Observational study of 72 consecutive patients (74 eyes) treated at Jules Gonin University Eye Hospital, Lausanne, with intravitreal ranibizumab 0.5 mg for classic choroidal neovascularization (CNV) between March 2006 and February 2008. Best-corrected visual acuity (BCVA), fundus examination and optical coherence tomography were recorded monthly; fluorescein angiography was performed at baseline and repeated at least every 3 months. RESULTS: RPE tears occurred in four (5.4%) eyes temporal to the fovea, after a mean of four injections (range 3-6). Mean baseline BCVA was 0.25 decimal equivalent (logMAR 0.67) and improved despite the RPE tear to 0.6 decimal equivalent (logMAR 0.22). CONCLUSION: RPE tears following intravitreal ranibizumab injections for classic CNV can occur in about 5% of patients, even in the absence of baseline RPE detachment. Nevertheless, vision may improve provided the fovea is not involved.

Autofluorescence Findings Of A Novel Maculopathy In Patient With Spinocerebellar Ataxia Type 1 And Of A Cone - Rod Type Retinal Dysfunction In Three Generation Family With Spinocerebellar Ataxia Type 7

Purpose: To report a novel maculopathy in a patient with SCA1. To describe autofluorescence findings in family with SCA7 and associated cone-rod retinal dysfunction.Methods: 4 affected patients from two families were assessed to investigate a progressive loss of visual acuity (VA). Examinations included fundus photography, autofluorescence (AF) fundus fluorescein angiogragraphy (FFA) and optical coherence tomography. Electroretinogram (full-field) was performed in 2 affected patients. All patients had color vision testing using Ishihara pseudoisochromatic plates. Molecular analysis was performed in family 2.Results: The patient with known diagnosis of SCA1 had a visual acuity of 20/200 bilaterally and dyschromatopsia. He had saccadic pursuit. Fundus examination showed mild retinal pigment epithelium (RPE) changes at the macula. OCT showed bilateral macular serous detachment, which was not obvious at the FFA and explained his VA. AF imaging showed a central hyperfluorescence. The 45 year old proband from family 2 had a visual acuity of 200/20 and dyschromatopsia. ERG testing showed cone type dysfunction of photoreceptors. Her daughter affected at a younger age had the same ERGs findings. Fundus examination showed mild RPE changes in proband, normal findings in her daughter. AF imaging of both patients showed a ring of high density AF around the fovea. The ring was also obvious on near infrared AF. Later onset of gait imbalance led to the diagnosis of SCA7Conclusions: Within the group of spinocerebellar ataxias, only the type 7 is associated with retinal dysfunction. We present the first report of maculopathy associated with SCA1 causing severe vision loss. The ring of high density AF in SCA7 confirmed an early retinal photoreceptor dysfunction in patient with normal fundus.

Consuming sports: distinction, univorism and omnivorism

The question of the social usages of culture and its links with social groups continues to be a topic of discussion today. The aim of this article is to contribute to the debate by examining coherence in the choice of physical activities and sports. The study focuses on the upper social groups, questioning, from a macro-sociological standpoint, their possible omnivority and their dissonance of choice with regard to these activities. Based on a quantitative survey of the sports participated in by the French, the study shows that omnivority and massification of activities are major phenomena. However, the upper social groups in France remain distinguishable both in terms of their "high level of omnivority" and their choice of distinctive activities. Dissonance is another of their characteristics but to a lesser extent.

International Capital Flows to Emerging and Developing Countries: National and Global Determinants

This paper examines international capital flows to emerging and developing countries. We assess whether commonalities exist, the permanence of shocks to commonalities and their determinants. Also, we consider individual country coherence with global capital flows and we measure the extent of co-movements in the volatility of capital flows. Our results suggest there are commonalities in capital inflows, although aggregate or disaggregate capital flows respond differently to shocks. We find that the US long run real interest rate is an important determinant of global capital flows, and real commodity prices are relevant but to a lesser extent. We also find a role for human capital in explaining why some countries can successfully ride the wave of financial globalisation.

Treatment of central retinal vein occlusion-related macular edema with intravitreal bevacizumab (Avastin): preliminary results.

PURPOSE: To assess the safety and efficacy of treatment of macular edema secondary to central retinal vein occlusion (CRVO) with intravitreal bevacizumab. PATIENTS AND METHOD: The ongoing prospective study included 8 consecutive patients (8 eyes) with macular edema secondary to CRVO (6 non ischemic and 2 ischemic), treated with intravitreal injection of 1.25 mg (0.05 mL) of bevacizumab. Main outcome was best corrected visual acuity (BCVA) and central foveal thickness (CFT) measured by optical coherence tomography monthly during one year. Retreatment criteria include decrease of BCVA, persistence of macular edema on angiograms and increase of CFT. RESULTS: Mean age of the eight patients was 68 years (range: 50-82 years). Mean duration of symptoms before injection was 98 days (range: 3-289). Mean follow-up was 3.25 months. At baseline, mean BCVA was 0.84 logMar and mean baseline CFT was 771 microm. Mean BCVA was 0.36 and mean CFT thickness was 275 microm (n = 8) at month 1, 0.41 and 411 microm at month 2 (n = 7), 0.3 and 344 microm at month 3 (n = 6), 0.3 and 397 microm at month 4 (n = 5), respectively. In 75 % of patients, a single injection was not sufficient, and retreatment needed. No serious adverse events were observed. CONCLUSIONS: Treatment of macular edema secondary to CRVO with intravitreal bevacizumab injection of 1.25 mg was well tolerated and associated with marked macular thickness reduction and BCVA improvement in all patients. A trend towards reduction of foveal thickness and improvement of visual acuity was observed in both acute and chronic CRVO.

The reasons for discrepancies in target volume delineation : a SASRO study on head-and-neck and prostate cancers.

PURPOSE: To understand the reasons for differences in the delineation of target volumes between physicians. MATERIAL AND METHODS: 18 Swiss radiooncology centers were invited to delineate volumes for one prostate and one head-and-neck case. In addition, a questionnaire was sent to evaluate the differences in the volume definition (GTV [gross tumor volume], CTV [clinical target volume], PTV [planning target volume]), the various estimated margins, and the nodes at risk. Coherence between drawn and stated margins by centers was calculated. The questionnaire also included a nonspecific series of questions regarding planning methods in each institution. RESULTS: Fairly large differences in the drawn volumes were seen between the centers in both cases and also in the definition of volumes. Correlation between drawn and stated margins was fair in the prostate case and poor in the head-and-neck case. The questionnaire revealed important differences in the planning methods between centers. CONCLUSION: These large differences could be explained by (1) a variable knowledge/interpretation of ICRU definitions, (2) variable interpretations of the potential microscopic extent, (3) difficulties in GTV identification, (4) differences in the concept, and (5) incoherence between theory (i.e., stated margins) and practice (i.e., drawn margins).

High magnification cystoscopy in the primary diagnosis of bladder tumors.

Purpose of reviewIn bladder cancer, discrimination between benign and malignant tissue may remain tricky with current endoscopic tools. On the basis of our recent experience with high-magnification cystoscopy, compared with other tools such as optical coherence tomography or confocal laser endomicroscopy, it is suggested here that this discrimination may well be feasible endoscopically. The clinical potential of these systems that are being developed as complementary tools to the current endoscopic equipment is reviewed.Recent findingsAt present, white-light cystoscopy, either assisted by fluorescence cystoscopy or narrow-band imaging, is proposed for the global cystoscopic examination of bladder cancer patients. Both techniques compete to help to reduce the recurrence rate by improving exophytic tumor detection, and the extent of carcinoma in situ and high-grade dysplasia. All of which are important prognosis factors for disease progression. In addition, recent findings on neoangiogenesis that accompanies early stage bladder cancer show that this may also be an important observable switch in bladder cancerogenesis, as it is found very early in tumor development. The high magnification cystoscopy as a complementary tool to fluorescence cystoscopy allows classification of the vessel patterns on fluorescence positive sites, and thus facilitates the discrimination between cancerous and noncancerous lesions. This information may be useful to reduce the false positive rate of fluorescence cystoscopy.SummaryEmerging technologies aiming at a real-time in-situ discrimination between benign and malignant tissue during endoscopic bladder exploration is a promising development for the monitoring of bladder cancer patients.

The Enigma of the Silent Closing of Acts (28,16-31)

(Résumé de l'ouvrage) In the first volume of this long-anticipated collection by Moessner and Tiede, seventeen leading scholars of antiquity present an amazing "sea change" of opinion that Luke is indeed the interpreter of Israel. The book represents an unprecedented international consensus that the Hellenistic author Luke composed a carefully crafted narrative in two parts to claim Jesus of Nazareth as Israel's true heritage and enduring legacy to the world. Part One explores the nature of Luke's prologues and his intention to write a narrative of "events brought to fruition," using the narrative conventions and audience expectations of the Greco-Roman milieu. Part Two illuminates the relation of Luke's second "volume" to the first by inquiring about the consistency and coherence of his narrative-thematic strategies in retelling the story of Israel's legacy of "the Christ." Whether Luke completed Acts, the larger role of Paul and, most significantly, the meaning of Israel by the end of Acts are approached from new perspectives and charged with provocative insights. In addition to the volume editors, the contributors include L. Alexander, D. Schmidt, V. Robbins, C. Thornton, R. Pervo, W. Kurz, C. Holladay, G. Sterling, D. Balch, E. Plmacher, Charles H. Talbert, J.H. Hayes, D. Marguerat, M. Wolter, R. Tannehill, and I. H. Marshall.
