The Distant neighbors — EU, Middle East, North Africa and the Euro-Mediterranean Partnership

The Barcelona Euro-Mediterranean Conference (1995) was intended to be a launching pad" for creating a new, innovative relationship between the EU-Fifteen and a selected set of non-member Middle Eastern and North African countries. The Barcelona Process was to become the European Union´s first attempt, of several, to create postmodern inclusive policy spheres as a way to deal with the post-enlargement problems of ´ins´ and outs´ in its immediate periphery. Nevertheless, in spite of geographical proximity, common problems and stated interest in creating amorphous EU borders in different sectors, the Euro-Mediterranean Partnership is today all but abandoned. This paper will examine some of the factors behind the current degeneration of the EU´s post-bipolar foreign policy strategy in the Mediterranean, by exploring the dialectic between the Union´s desire to expand its geopolitical, economic and cultural boundaries and the need to secure its territorial area (from migration, proliferation, social instability etc.). In the final part of the paper some suggestions for how to revive the relationship across the Mare Nostrum will be forwarded.

La Pacificación en el mundo actual. Estrategias europeas para la resolución de conflictos

¿Cómo se podría comprometer la Comunidad Internacional, en un mundo globalizado, para la resolución de conflictos?. En el siglo XXI, pasa necesariamente por un cuestionamiento de los métodos tradicionalmente empleados para la resolución de conflictos y la seguridad (frente a nuevos escenarios nuevas estrategias). Éstas toman forma en las doctrinas de la prevención, transformación, resolución de conflictos, gestión de crisis, y seguridad multidimensional/colectiva. Trasladándolo a Europa, la implantación de políticas comunes en las zonas en conflicto, urge cada día más. No existe una acción exterior colectiva ante el estallido de una crisis, porque al final siempre acaban prevaleciendo las decisiones de los Estados más poderosos. Es este mismo proceso decisional, anclado en las posturas realistas, el que bloquea o retarda todo intento de reacción común. Mientras, la violencia se sucede y asistimos impotentes a escenarios bélicos o escaladas, bajo la mirada atrapada de Occidente. La UE se enfrenta a un desafío cada vez más presente, por conseguir una acción globalizadora en materia de derechos humanos, porque frente a la globalización económica surge la necesidad de contrarestar sus efectos, globalizando también los derechos humanos. Cabría revisar las respuestas y capacidades europeas ante el estallido de una crisis.

L'adaptació de la norma als centres de menors. Estudi del Centre Educatiu L'Alzina

Aquesta investigació és una aproximació al procés d’adaptació a la Llei 5/2000, reguladora de la responsabilitat penal dels menors, al Centre Educatiu L’Alzina. La recerca constitueix un intent d’anar més enllà d’allò merament descriptiu, en un esforç per fer palesa la racionalitat subjacent a la pràctica quotidiana i a la lògica implícita a l’intervenció educativa amagada sota nocions centrals en el seu desenvolupament, com ara progrés, retrocés, càstig, recompensa, activitat esportiva o pauta mèdica. Els autors proposen una interpretació que implica la consolidació d’una lògica de la simulació netament allunyada de la lògica dels fets que, formalment, plana sobre la dinàmica de l’aplicació de la norma al Centre.

Giant extra-hepatic thrombosed portal vein aneurysm: a case report and review of the literature.

BACKGROUND: Extrahepatic Portal vein aneurysm (EPVA) is a rare finding that may be associated with different complications, e.g. thrombosis, rupture, portal hypertension and compression of adjacent structures. It is being diagnosed more frequently with the advent of modern cross-sectional imaging. Our review of the English literature disclosed 13 cases of thrombosed EPVA. CASE PRESENTATION: A 50-years-old woman presented with acute abdominal pain but no other symptom. She had no relevant medical history. Palpation of the right upper quadrant showed tenderness. Laboratory tests were unremarkable. A computed tomography showed portal vein aneurysm measuring 88 × 65 mm with thrombosis extending to the superior mesenteric and splenic vein. The patient was treated conservatively with anticoagulation therapy. She was released after two weeks and followed on an outpatient basis. At two months, she reported decreased abdominal pain and her physical examination was normal. A computed tomography was performed showing a decreased thrombosis size and extent, measuring 80 × 55 mm. CONCLUSIONS: Although rare, surgeons should be made aware of this entity. Complications are various. Conservative therapy should be chosen in first intent in most cases. We reported the case of the second largest thrombosed extra-hepatic PVA described in the literature, treated by anticoagulation therapy with a good clinical and radiological response.

Kernel-based methods for change detection in remote sensing images

Nowadays, the joint exploitation of images acquired daily by remote sensing instruments and of images available from archives allows a detailed monitoring of the transitions occurring at the surface of the Earth. These modifications of the land cover generate spectral discrepancies that can be detected via the analysis of remote sensing images. Independently from the origin of the images and of type of surface change, a correct processing of such data implies the adoption of flexible, robust and possibly nonlinear method, to correctly account for the complex statistical relationships characterizing the pixels of the images. This Thesis deals with the development and the application of advanced statistical methods for multi-temporal optical remote sensing image processing tasks. Three different families of machine learning models have been explored and fundamental solutions for change detection problems are provided. In the first part, change detection with user supervision has been considered. In a first application, a nonlinear classifier has been applied with the intent of precisely delineating flooded regions from a pair of images. In a second case study, the spatial context of each pixel has been injected into another nonlinear classifier to obtain a precise mapping of new urban structures. In both cases, the user provides the classifier with examples of what he believes has changed or not. In the second part, a completely automatic and unsupervised method for precise binary detection of changes has been proposed. The technique allows a very accurate mapping without any user intervention, resulting particularly useful when readiness and reaction times of the system are a crucial constraint. In the third, the problem of statistical distributions shifting between acquisitions is studied. Two approaches to transform the couple of bi-temporal images and reduce their differences unrelated to changes in land cover are studied. The methods align the distributions of the images, so that the pixel-wise comparison could be carried out with higher accuracy. Furthermore, the second method can deal with images from different sensors, no matter the dimensionality of the data nor the spectral information content. This opens the doors to possible solutions for a crucial problem in the field: detecting changes when the images have been acquired by two different sensors.

Treatment of advanced ovarian cancer with surgery, chemotherapy, and consolidation of response by whole-abdominal radiotherapy.

Between April 1981 and June 1985, 195 patients with ovarian cancer, International Federation of Gynecology and Obstetrics (FIGO) Stages IIB, IIC, III, and IV, entered a trial that consisted of surgery and chemotherapy with cisplatin (P) and melphalan (PAM) with or without hexamethylmelamine (HexaPAMP or PAMP regimens) every 4 weeks for 6 cycles. Because the intent was to study the outcome by treatment after evaluation of first-line chemotherapy, patients were evaluable only if the response was assessed by a second-look operation or if measurable disease progression was documented. One hundred fifty-eight patients (81%) were evaluable for response. Forty-five (28%) achieved pathologically confirmed complete remissions (pCR), and 24 of these patients received whole-abdominal radiation (WAR) for consolidation of response. Five patients with complete remission after WAR relapsed, as did nine of the 21 with complete remission who had not undergone WAR. The 3-year time to progression percentage (TTP +/- SE) from second-look operation was 70% +/- 7% for all patients who achieved pCR, 83% +/- 8% for those who received WAR, and 49% +/- 15% for those who did not receive WAR (this was not a randomized comparison). The 3-year TTP percentage for the 49 partial responders was 21% +/- 6%, identical for the 19 who had WAR and the 30 who had no radiation therapy. Additional or alternative methods for consolidation of pCR are needed since patients continue to relapse despite optimal initial response to therapy.

Colorectal cancer and thoracic surgeons: close encounters of the third kind.

Resection of lung metastases from colorectal cancer (CRC) is increasingly performed with a curative intent. This strategy was made possible in the 1990s by the development of new chemotherapeutic approaches, improved surgical techniques and better imaging modalities. However, evidence-based data showing clinical benefits of lung metastasectomy in this setting are nonexistent, and there are no prospective randomized trials to support the routine performance of these procedures for stage IV CRC. Current evidence suggests that resection of pulmonary metastases in combination with new cytotoxic agents, such as oxaliplatin, irinotecan and bevacizumab, may result in prolonged survival for many, and cure for a small minority of CRC patients who experienced tumor spread beyond the limits of the abdomen. This review focuses on the results of surgical management of CRC patients with lung metastases: we report the outcome of published series according to the presence or the absence of liver metastasis (and hepatic resection) prior to lung resection.

Updated survival data of the phase iii clinical trial of novottf-100a versus best standard chemotherapy for recurrent glioblastoma

NovoTTF-100A (TTF) is a portable device delivering low-intensity, intermediate-frequency, alternating electric fields using noninvasive, disposable scalp electrodes. TTF interferes with tumor cell division, and it has been approved by the US Food and Drug Administration (FDA) for the treatment of recurrent glioblastoma (rGBM) based on data from a phase III trial. This presentation describes the updated survival data 2 years after completing recruitment. Adults with rGBM (KPS ≥ 70) were randomized (stratified by surgery and center) to either continuous TTF (20-24 h/day, 7 days/week) or efficacious chemotherapy based on best physician choice (BPC). The primary endpoint was overall survival (OS), and secondary endpoints were PFS6, 1-year survival, and QOL. Patients were randomized (28 US and European centers) to either TTF alone (n ¼ 120) or BPC (n ¼ 117). Patient characteristics were balanced, median age was 54 years (range, 23-80 years), and median KPS was 80 (range, 50-100). One quarter of the patients had debulking surgery, and over half of the patients were at their second or later recurrence. OS in the intent-to-treat (ITT) population was equivalent in TTF versus BPC patients (median OS, 6.6vs. 6.0 months; n ¼ 237; p ¼ 0.26; HR ¼ 0.86). With a median follow-up of 33.6 months, long-term survival in the TTF group was higher than that in the BPC group at 2, 3, and 4 years of follow-up (9.3% vs. 6.6%; 8.4% vs. 1.4%; 8.4% vs. 0.0%, respectively). Analysis of patients who received at least one treatment course demonstrated a survival benefit for TTF patients compared to BPC patients (median OS, 7.8 vs. 6.0 months; n ¼ 93 vs. n ¼ 117; p ¼ 0.012; HR ¼ 0.69). In this group, 1-year survival was 28% vs. 20%, and PFS6 was 26.2% vs. 15.2% (p ¼ 0.034). TTF, a noninvasive, novel cancer treatment modality shows significant therapeutic efficacy with promising long-term survival results. The impact of TTF was more pronounced when comparing only patients who received the minimal treatment course. A large-scale phase III trial in newly diagnosed GBM is ongoing.

On codes, matroids, and secure multiparty computation from linear secret-sharing schemes

Error-correcting codes and matroids have been widely used in the study of ordinary secret sharing schemes. In this paper, the connections between codes, matroids, and a special class of secret sharing schemes, namely, multiplicative linear secret sharing schemes (LSSSs), are studied. Such schemes are known to enable multiparty computation protocols secure against general (nonthreshold) adversaries.Two open problems related to the complexity of multiplicative LSSSs are considered in this paper. The first one deals with strongly multiplicative LSSSs. As opposed to the case of multiplicative LSSSs, it is not known whether there is an efficient method to transform an LSSS into a strongly multiplicative LSSS for the same access structure with a polynomial increase of the complexity. A property of strongly multiplicative LSSSs that could be useful in solving this problem is proved. Namely, using a suitable generalization of the well-known Berlekamp–Welch decoder, it is shown that all strongly multiplicative LSSSs enable efficient reconstruction of a shared secret in the presence of malicious faults. The second one is to characterize the access structures of ideal multiplicative LSSSs. Specifically, the considered open problem is to determine whether all self-dual vector space access structures are in this situation. By the aforementioned connection, this in fact constitutes an open problem about matroid theory, since it can be restated in terms of representability of identically self-dual matroids by self-dual codes. A new concept is introduced, the flat-partition, that provides a useful classification of identically self-dual matroids. Uniform identically self-dual matroids, which are known to be representable by self-dual codes, form one of the classes. It is proved that this property also holds for the family of matroids that, in a natural way, is the next class in the above classification: the identically self-dual bipartite matroids.

Procalcitonin for reduced antibiotic exposure in ventilator-associated pneumonia: a randomised study.

In patients with ventilator-associated pneumonia (VAP), guidelines recommend antibiotic therapy adjustment according to microbiology results after 72 h. Circulating procalcitonin levels may provide evidence that facilitates the reduction of antibiotic therapy. In a multicentre, randomised, controlled trial, 101 patients with VAP were assigned to an antibiotic discontinuation strategy according to guidelines (control group) or to serum procalcitonin concentrations (procalcitonin group) with an antibiotic regimen selected by the treating physician. The primary end-point was antibiotic-free days alive assessed 28 days after VAP onset and analysed on an intent-to-treat basis. Procalcitonin determination significantly increased the number of antibiotic free-days alive 28 days after VAP onset (13 (2-21) days versus 9.5 (1.5-17) days). This translated into a reduction in the overall duration of antibiotic therapy of 27% in the procalcitonin group (p = 0.038). After adjustment for age, microbiology and centre effect, the rate of antibiotic discontinuation on day 28 remained higher in the procalcitonin group compared with patients treated according to guidelines (hazard rate 1.6, 95% CI 1.02-2.71). The number of mechanical ventilation-free days alive, intensive care unit-free days alive, length of hospital stay and mortality rate on day 28 for the two groups were similar. Serum procalcitonin reduces antibiotic therapy exposure in patients with ventilator associated pneumonia.

Contribuição dos factores motivacionais para a satisfação no trabalho

A motivação é vista, desde meados do Século XX, como o principal factor de satisfação no trabalho, de aumento da produtividade e de melhoria da qualidade dos produtos e serviços. Na conclusão de um curso conducente ao Mestrado em Gestão Global, interessou-nos abordar o valor humano da organização, cujo componente importante é o nível de satisfação das pessoas no trabalho, obtido da avaliação a um leque de variáveis independentes, relacionadas com duas coisas – o conteúdo do trabalho e o contexto do trabalho. O objectivo da presente dissertação é identificar em que medida as variáveis do meio envolvente do trabalho contribui para a satisfação no trabalho. Inspirados na Teoria dos dois Factores (Herzberg, 1959 e 1982) e na Teoria da Avaliação Cognitiva (Deci, 1971), pretendemos justapor a satisfação das pessoas à diferentes variáveis particulares que formam dois subsistemas – o intrínseco ou motivador, que inclui a aprendizagem, as emoções, o trabalho em si, a realização e o reconhecimento; e o extrínseco ou higiénico, que inclui o salário, a supervisão e as condições físicas. Além de uma incursão à literatura especializada, realizamos dois inquéritos em empresas cabo-verdianas, um em Outubro de 2003 e outro em Outubro de 2007, que nos permitiram determinar índices específicos e gerais de satisfação no trabalho, fazer correlações e análises comparativas. Concluímos que as pessoas estão razoavelmente satisfeitas no trabalho, dão mais ênfase aos factores do conteúdo que aos factores do contexto do trabalho, mas a fonte de satisfação varia de categoria por categoria. Work motivation is viewed, since middle of the 20th Century, as a main factor of job satisfaction, also for increasing of productivity and quality of goods and services. By the ending of a Master’s Programme in Global Management, we was moved by a great interest to research and report about the organization human values, important component of which is the people’s satisfaction level in work conditions, obtained through an evaluation of a great number of independent variables, related to two items – work content and work context. The main objective of the present dissertation is to identify in which measure the job environmental variables contribute to work satisfaction. Inspired into the Two Factors Theory (Herzberg, 1959, 1982) and into The Cognitive Evaluation Theory (Deci, 1971), we intent to relate people satisfaction to different particular variables, which perform two subsystems – intrinsic or motivator, that includes learning, emotions, work itself, achievement and recognition and; extrinsic or hygienic, that includes salary, supervision and work physical conditions. Besides a specialized literature review, we took up two separated inquiries within capeverdian companies, the first conducted in October, 2003, and the second in October, 2007, which allowed specifics and general job satisfaction indexes, correlations and comparative analysis. We concluded that people are fair satisfied on job, and give more emphasis on work content factors, than on work context factors, but the source of satisfaction is different category by category.

Survival after lung metastasectomy in colorectal cancer patients with previously resected liver metastases.

BACKGROUND: Resection of hepatic metastases is indicated in selected stage IV colorectal cancer (CRC) patients. A minority will eventually develop pulmonary metastases and may undergo lung surgery with curative intent. The aims of the present study were to assess clinical outcome and identify parameters predicting survival after pulmonary metastasectomy in patients who underwent prior resection of hepatic CRC metastases.¦METHODS: We performed a retrospective analysis of 27 consecutive patients (median age 62 years; range: 33-75 years) who underwent resection of pulmonary metastases after previous hepatic metastasectomy from CRC in two institutions from 1996 to 2009. All patients underwent complete resection (R0) for both colorectal and hepatic metastases.¦RESULTS: Median follow-up was 32 months (range: 3-69 months) after resection of lung metastases and 65 months (range: 19-146 months) after resection of primary CRC. Three- and 5-year overall survival rates after lung surgery were 56 and 39%, respectively, and median survival was 46 months (95% CI 35-57). Median disease-free survival after pulmonary metastasectomy was 13 months (95% CI 5-21). At the time of last follow-up, seven patients (26%) had no evidence of recurrent disease and 6 of these 7 patients presented initially with a single lung metastasis.¦CONCLUSIONS: Resection of lung metastases from CRC patients may result in prolonged survival, even after previous hepatic metastasectomy. Yet, prolonged disease-free survival remains the exception, and seems to occur only in patients with a single lung lesion.
