Abstract:

To summarize ophthalmological signs of monoclonal gammopathy of undetermined significance (MGUS) and to present a case report. Summary of the literature data and presentation of the history of a 46-year-old female patient. In MGUS, pathological, but non-malignant plasma cells produce abnormal monoclonal immunoglobulin. Its prevalence is 0.15%, but it increases with age. As yearly 1–2% of MGUS patients develop multiple myeloma, frequent hematological follow-up is necessary. Corneal opacifications in MGUS have been described in a few dozens of patients in the literature. These may be nummular or crystal-like, or even present with white or grey line-forming depositions in the stroma. They may be centrally or peripherally localized. In our patient, bilateral, branching, geographical corneal opacifications were detected predescemetally, that were progressing and reaching the optical centre during follow-up. With 0.15 best corrected visual acuity, penetrating keratoplasty was performed (postoperative best spectacle-corrected visual acuity 0.6). Masson trichrom staining of the explanted cornea verified protein deposition, immunhistochemistry identified kappa light chain immunglobulin deposition in the posterior stroma, surrounded with inflammatory cells. Serum electrophoresis and bone marrow biopsy of our patient proved MGUS, therefore, hematological follow-up is going on. In the case of progressive, atypical corneal opacification, the hematological diagnosis of monoclonal gammopathy must be excluded – monoclonal gammopathy of ocular significance –, as delay in proper diagnosis and treatment of the systemic disease may have devastating consequences.

ABSTRACT Introduction: The prevalence of excess weight/obesity in adolescence has increased, and physical training may be effective in combating this scenario. Objective: To analyze the effect of different intensities of aerobic training on the body composition of obese adolescents undergoing multidisciplinary intervention. Methods: In this study, 107 pubertal (Tanner 3 and 4), obese (BMI=34.72±4.10 kg/m²) adolescents (14.85±1.44 years) were randomly assigned to three groups: high intensity training (HITG – ventilatory threshold I (VTI)); low intensity training (LITG – 20% below the VTI) and control group (CG), without intervention. The adolescents in the HITG and LITG underwent nutritional and psychological (1x/week) and clinical (1 x/month) follow-up and physical training (3x/week) for 12 weeks. Results: Reductions in fat mass (FM) and body fat percentage (BFP) (p< 0.001) and an increase in fat-free mass (FFM) (p<0.001) were observed in all groups. There was a reduction in BMI only in the experimental groups (p<0.001). Conclusion: The effects of multidisciplinary treatment on the body composition of obese adolescents occur independently of the intensity of aerobic physical training.

TREATMENT OF SPORT INJURIES WITH ACUPUNCTURE: A LITERATURE REVIEW
Authors: Gentil Luiza Borges
Published: October 2018

ABSTRACT As acupuncture is growing in popularity in Brazil and worldwide, it is necessary to study the benefits and possibilities of this type of treatment more in depth, especially as it is believed to produce fast results with few side effects and does not involve substances banned in sports. Thus, it seems like a good option to be considered as main or adjuvant therapy in sports-related injuries. In order to gain more knowledge about this subject, this article is an integrative review analyzing the publications of the period between January 2012 and January 2017 on the Cochrane and Pubmed platforms that analyzed acupuncture in the treatment of sports injuries. We found 49 articles, 11 of which fulfilled the inclusion criteria: two case reports, three clinical trials and six literature reviews. Although all the articles analyzed produced favorable results with the use of the therapeutic technique in question, flaws in the designs of the studies and the difficulty of creating a placebo control group in acupuncture hinder the qualification of the articles on evidence rating scales. Therefore, it is suggested to the researchers that further studies be published with experimental animal models and observational studies, and that STRICTA recommendations be followed to improve the level of evidence of acupuncture research.

Published: October 2018

ABSTRACT Introduction: The region between the ventilatory threshold (VT) and respiratory compensation point (RCP) is defined as the isocapnic buffering (ICB) phase and represents a phase of compensation for exercise-induced metabolic acidosis. There is sparse literature examining the effects of physical training on ICB phase in athletes. Objectives: The purpose of this study was to examine the effects of a repeated sprint training program on the ICB phase of college volleyball players. Methods: Eighteen male volleyball players were randomly assigned to either an experimental group (n=9) or a control group (n=9) and followed a traditional volleyball training program three times per week for six weeks. The experimental group additionally performed a repeated sprint training protocol immediately before each volleyball training session. Before and after the 6-week training period, all participants performed an incremental treadmill test to determine VT, RCP, and maximal oxygen uptake (VO2max). The ICB phases were calculated as VO2 (ml/kg/min) and sprint speed (km/h). Results: The experimental group showed significant improvements in ICB phase, RCP, VO2max and maximal sprint speed after training (p<0.01). There were no significant changes in VT after training in the experimental group (p>0.05). None of these variables changed significantly in the control group (p>0.05). Conclusions: These findings indicate that repeated sprint training can enhance the ICB phase of volleyball players, which may be attributable to an improvement in buffering capacity leading to a shift in RCP towards higher intensities without any change in VT. The increase in the ICB phase may an important factor in terms of improvement in the high-intensity exercise tolerance of athletes.

Authors: Alvaro Mateos-Angulo , Alejandro Galán-Mercant , Ignacio Cuesta-Vargas Antonio
Published: October 2018

ABSTRACT Introduction: Vertical jump tests can be used as estimators of muscular power, physical capacity, motor development and functional capacity. The ability to jump can be analyzed with different methods, including the use of inertial sensors. Objective: To describe and analyze kinematic characteristics using the inertial sensor integrated into the iPhone 4S® and jump contact mat variables in the squat jump (SJ) and countermovement jump (CMJ) tests, and to determine the interaction between kinetic and kinematic variables. Methods: A cross-sectional study was conducted with 27 healthy young adults. The primary outcome measures were linear acceleration, flight time, contact time, jump height and dynamometry of the knee extensors. Spearman's rho was used to investigate the correlation between variables. The Mann–Whitney U rank-sum test was used for the analysis of intergender variance. Results: The greatest difference between groups (gender) was in the dynamometry variables (p<0.001) and contact mat variables (p<0.001). Between the jump tests, the greatest difference between groups (gender) was in the CMJ test (p<0.001). Conclusion: The inertial sensor embedded in the smartphone demonstrated a correlation with the jump mat and the dynamometry. Finally, the higher kinetic and kinematic scores observed in the jumps performed by male participants than in those performed by female participants suggest that they can be used to better characterize their jumping profile.

Published: October 2018

A study of the effects of citric acid on the mechanical properties of calcium sulfoaluminate (C4A3S̄) cements in hydraulic pastes and mortars was performed. Clinker made up of C4A3S̄ was obtained from the calcination of a mixture of fly ash, aluminium dross and fluorogypsum at 1100°C. The C4A3S̄ cement was prepared by mixing the clinker with certain percentages of commercial hemihydrate. Hydraulic pastes and mortars were prepared with 0·05% citric acid relative to the total weight of the cement in order to slow down the reactions and also to act as a structural modifier. The initial and final setting times of the pastes were up to 189 and 336 min, respectively. The compressive strength was evaluated in specimens cured at room temperature, reaching, in some mortar formulations, more than 80 MPa at 360 d with high initial development. Hydration reactions were significantly affected by both the citric acid and the increase in temperature, as confirmed by isothermal conduction calorimetry. The main hydration product was ettringite, which promoted the formation of dense and compact microstructures.
Hydration of geosynthetic clay liners (GCLs) on compacted zeolite
Authors: Özdamar Kul T. , Ören A. H.
Published: October 2018

The hydration performance of two geosynthetic clay liners (GCLs) over compacted zeolite is investigated in this paper. Zeolite was chosen as the subsoil because of its greater optimum water content with respect to other natural soils (41%). The water content changes of GCL-1 and GCL-2, which each had distinct properties, were the same until 30 days of hydration. The water content of GCL-1 increased from 120% to 147% after 62 days of hydration and then decreased to 117% after 90 days of hydration. However, the water content of GCL-2 was greater than that of GCL-1 (149% vs. 117%) after 90 days of hydration. The reduction in the water content of GCL-1 after 90 days was due to cation replacement. The exchangeable mole fractions of sodium cations (XNa) decreased whereas exchangeable mole fractions of divalent cations (XCa and XMg) increased with the duration of hydration. Cation replacement was more pronounced for GCL-1 than for GCL-2. Although swell indices decreased markedly with the durations of hydration, the final hydraulic conductivities of GCL-1 and GCL-2 were almost the same, around 2.0 × 10−11 m/s. This means higher water content masked the negative influence of cation replacement, resulting in comparable and low hydraulic conductivities for both GCLs.

Published: October 2018

A partir de uma intervenção sobre sofrimento psíquico na universidade, buscamos compreender a experiência de vida na graduação em psicologia na contemporaneidade por meio de uma pesquisa qualitativa. Em outubro de 2017 foram produzidas narrativas com seis estudantes do 3º ano do curso de Psicologia da UNICENTRO, Irati, Paraná, Brasil, com média de 21 anos de idade, advindos de outras cidades do país. Eles revelaram significativa diferença entre as expectativas no ingresso na graduação e seu cotidiano e em como percebem e se posicionam perante a vida e o mundo atualmente. Narram sentir uma sobrecarga provocada por cinco fatores: a) curso público e integral com grade curricular extensa; b) diversidade de teorias, disciplinas e práticas ministradas ao mesmo tempo; c) quantidade de leituras, reflexões e/ou tarefas para além das aulas; d) conteúdo denso e inquietante; e) uma exigência ética da Psicologia. Relatam sofrimento na forma de distanciamento de familiares, amigos e atividades prazerosas; cansaço geral e mental, disfunções no sono, nervosismo, preocupação, ansiedade, angústia, culpa, tristeza e pressão e  solicitam a criação de múltiplos espaços de assistência estudantil. O estudo apontou para a multiplicidade de modos de ser estudante e experenciar a graduação, e para a complexidade dessa vivência constituída em um mundo em constante mutação e produção de demandas. Indica a urgência da Universidade e seus diferentes atores refletirem sobre seu papel diante de novas questões oriundas da maior diversidade de estudantes e suas necessidades. São essenciais pesquisas com maior número de acadêmicos, de distintos cursos e instituições.

Published: October 2018

В настоящей работе рассматривается малая капля жидкости, которая лежит на горизонтальной гладкой поверхности в поле силы тяжести и пребывает в термодинамическом равновесии с собственным паром. С учетом размерной зависимости поверхностного натяжения получено уравнение, которое выступает в роли основного условия механического равновесия капли. Данное уравнение является аналогом уравнения Башфорта – Адамса, хорошо известного из математической теории равновесных капиллярных поверхностей. Исходя из аналога уравнения Башфорта – Адамса получены системы нелинейных дифференциальных уравнений первого порядка, описывающие профиль капли. Найдена связь между координатами произвольной точки на поверхности капли и объемом заключенной жидкости. На вычислительном эксперименте смоделировано изменение линейных размеров капли с увеличением объема жидкости. Все указанные уравнения и формулы переходят в ранее известные, если в них параметр, отвечающий за размерный эффект поверхностного натяжения, приравнять к нулю.
CLASHES OF CONSCIENCE:EXPLAINING COUNTERDEMONSTRATION AT PROTESTS*
Authors: Reynolds-Stenson Heidi , Earl Jennifer
Published: October 2018

Whether in contemporary protests or in key movements in United States history, protesters must often contend with police and sometimes also with counterprotesters. Clashes with counterprotesters are often tense, ripe with the possibility of violence, and increase the chance of a police response. Although there is research on countermovements, there is little on counterprotesting. We conduct a systematic, cross-movement analysis to forward a strategic threatbased explanation of counterprotesting. We examine the frequency of counterdemonstration, the relative merits of threat versus weakness explanations of counterdemonstrator mobilization, and the relationship between counterdemonstrating and protest policing. We find that counterprotesting is relatively uncommon, is more common at conservative protests, and is explained by the threat posed by, and strength of, the initial movement. Furthermore, policing and counterdemonstrating appear positively and reciprocally related: we find that recent police repression increases counterdemonstration, and existing research shows that counterdemonstrators, in turn, increase police response.
ACTIVISM WITHOUT ACTIVISTS: NEWS MEDIA COVERAGE OF YOUTH AS ILLEGITIMATE POLITICAL AGENTS IN THE VIRGINITY-PLEDGE MOVEMENT AND GAY-STRAIGHT ALLIANCES*
Authors: Kettrey Heather Hensman
Published: October 2018

How do news media portray collective action involving activists who are deemed illegitimate political actors? The news media has a well-documented tendency to disparage adult activists by excluding their voices from coverage, attacking their political identities, and minimizing their collective action outcomes. However, the perceived illegitimacy of youth activists suggests they have no voices to be excluded, no political identities to be attacked, and no outcomes to minimize. This study analyzes coverage of the virginity pledge movement and gay-straight alliances in nationally circulated newspapers across two decades. Findings indicate youth activists' illegitimacy actually guaranteed youth a voice in the news media, but this came with unintended consequences. The news media used this perceived illegitimacy to undermine youth activists in three ways: (1) restricting youth voices to personal (apolitical) testimonies, (2) engaging in displaced disparagement by attacking adults and other legitimate targets, and (3) holding adults accountable for collective action outcomes.

Interculturalizar a formação de professores: leituras pela abertura epistemológica nos currículos de licenciaturas
Authors: Sant'Ana Jonathas Vilas Boas de , Suanno João Henrique , Silva Yara Fonseca de Oliveira e
Published: October 2018

A questão das diferenças culturais tem sido foco de muitos estudos educacionais contemporâneos. Busca-se, construir uma educação aberta às diferenças pautada no respeito e, na valorização da diversidade, o que exige repensar a formação inicial e continuada de professores. Assim, o objetivo deste estudo, de caráter teórico, (VILAÇA, 2010) é discutir a possibilidade de interculturalizar criticamente a formação de professores. Problematizamos as relações assimétricas produzidas pela colonialidade do poder (QUIJANO, 1992), entendendo as diferenças culturais como, criações discursivas (SILVA, 2014) historicamente hierarquizadas em uma educação monocultural (VEIGA-NETO, 2003) que vem sendo fortemente questionada por outros sujeitos e outras pedagogias (ARROYO, 2012). A perspectiva de educação intercultural (CANDAU, 2016) emerge neste contexto propondo uma abertura radical às diferenças (WALSH, 2010), inclusive em estudos sobre a formação de professores (CANEN; XAVIER, 2005; MELO 2014). Diante desta conjuntura, a proposição feita neste trabalho é que os cursos de licenciatura incluam em seus currículos epistemologias não-ocidentais a fim de interculturalizar radicalmente a formação de professores. Por fim, consideramos que esta proposta é um desafio que impulsiona a criação de outros modos de educar.
Dicionário Raciocinado das Licenciaturas: ornitorricando discursos no campo da formação de professores

Published: October 2018

Este artigo analisa uma pesquisa que tem investido em incentivar os licenciandos a expressarem aquilo que excede nos discursos da formação de professores. Tendo Roland Barthes, Michel Foucault e Gilles Deleuze como intercessores, detém-se em pensar a escrita enquanto provocação, ferramenta que põe em movimento e movimenta o excurso dos discursos mais sedimentados acerca da educação, que dizem da figura do professor nos dias atuais. Traz percepções que resultam de um exercício de estranhar o que se diz a respeito do “ser professor”. Desenvolvida junto a estudantes de licenciaturas da Universidade Federal do Rio Grande do Sul, tem feito da escrita e do escrever, reunidos pelo conceito de fantasia, um dispositivo de intervenção. Dando forma a esse exercício de estranhamento, nomeado ornitorrincar, uma vez que se utiliza da figura do ornitorrinco, cria o Dicionário Raciocinado das Licenciaturas, que se inspira em alguns procedimentos operados pela Encyclopédie ou Dictionaire Raisonné des Sciences, des Arts et des Métiers, de Denis Diderot e Jean d’Alembert. Composto por quatro Tomos e com um total de noventa e três licenciandos participantes, agencia uma produção coletiva de textos na forma de verbetes, resultado de provocações filosóficas e literárias. O ornitorrinco surge no projeto como imagem-guia, espécie de imagem-conceito que sintetiza a força de estranhamento e o trabalho do desconhecido, qualidades vitais à docência e, por conseguinte, à formação de professores. Tal desafio tem convocado os estudantes a se perceberem e a escreverem sobre essa experiência de tornar-se professor. Ao invés da simples denúncia, os verbetes que compõem o dicionário são um convite ao estranhamento dos lugares comuns que compõem a formação de professores, uma solicitação a ornitorrincarem concepções e experiências docentes.

Este artigo visa comunicar parte dos resultados de uma pesquisa que teve como objetivo desvelar as memórias de professores do Ensino Fundamental em fase final de carreira da Rede Municipal de Ensino de Blumenau (SC) sobre a formação continuada em serviço, vivenciada em suas carreiras docentes. Realizou-se uma pesquisa socio-histórica, de abordagem qualitativa, sustentada em Gatti e Barretto (2009), Davis, Nunes e Almeida (2011), Nóvoa (2009; 2013) e Imbernón (2010; 2011). Os dados foram gerados por meio de cartas pessoais e técnica de complemento. O método de análise empregado foi a Análise Textual Discursiva. A pesquisa envolveu 14 professores em fase final de carreira da Rede Municipal de Ensino de Blumenau (SC). Os resultados indicaram as seguintes marcas positivas: diferentes modalidades formativas; relevância do curso do Magistério em nível de Ensino Médio; cursos do governo federal; formadores da própria rede de ensino e de profissionais externos; formação durante o horário de trabalho; formações por áreas específicas do conhecimento e grupos menores; encontros formativos mensais ou quinzenais; espaço de formação comum; troca de experiências; parceria entre professor experiente e iniciante; protagonismo do professor; equilíbrio entre teoria e prática; formação na escola; e análise de situações problemáticas. Em relação às marcas negativas, os dados revelaram: problemas em relação à eficiência e à qualidade da formação ofertada pelos formadores da SEMED; ausência de formações inovadoras e atraentes; práticas ocasionais, ausência ou descontinuidade na formação; pouco tempo disponível para a realização da formação; falta de acolhimento no período de inserção profissional; ausência do trabalho colaborativo; comodismo, desinteresse do professor na formação; descontinuidade de políticas educacionais eficazes; opiniões dos professores não são ouvidas; e excesso de teoria distante da prática. Recomenda-se ouvir os professores em fase final de carreira e realizar diagnóstico das suas necessidades formativas para elaborar uma política de formação continuada.

Fibromyalgia in the mothers of the children with cerebral palsy, and determination of the related depression and anxiety situations
Authors: TOY Şeyma , BEYKUMÜL Ayşegül , AVCI Zeynep Tuğçe , BÜYÜKAVCI Raikan
Published: October 2018

Objectives: In this study, it was aimed to evaluate maternal functional status, quality of life, depression and anxiety measurements according to the child's functional level in the mothers, who were diagnosed with fibromyalgia syndrome (FMS), of children with cerebral palsy (CP). Methods: Ninety-seven mothers diagnosed with FMS, whose children had CP, were included in the study. Children with CP were divided into two functional levels with the Gross Motor Function Classification System (GMFCS) as mild-moderate (level 1, 2 and 3) and severe (level 4 and 5). On mothers, The Fibromyalgia Impact Questionnaire (FIQ) was used to assess the functional levels and quality of life, Beck Depression Inventory (BDI) was used to evaluate the depression level, and Beck Anxiety Inventory (BAI) was used to determine the anxiety level. Results: The mean age of the 97 female patients participating in the study was 35.93 ± 8.72 years. According to GMFCS, 67% of children with CP were mild to moderate while 33% were severe. There was a significant positive correlation between GMFCS levels of children with CP and their mother's FIQ, BDI, and BAI scores (p < 0.05). Conclusions: Maintaining the daily life of a child with CP is a parenting-focused situation. Especially it affects the mother physically and mentally. Our study suggests that the severe physical condition of the child with CP increases the mother's FIQ, depression, and anxiety. It has been determined that studies on CP should not ignore the parental factor as well as research on the disease itself.

Towards Autonomous Reinforcement Learning: Automatic Setting of Hyper-parameters using Bayesian Optimization
Authors: Barsce Juan Cruz , Palombarini Jorge Andrés , Martínez Ernesto Carlos
Published: October 2018

With the increase of machine learning usage by industries and scientific communities in a variety of tasks such as text mining, image recognition and self-driving cars, automatic setting of hyper-parameter in learning algorithms is a key factor for obtaining good performances regardless of user expertise in the inner workings of the techniques and methodologies. In particular, for a reinforcement learning algorithm, the efficiency of an agent learning a control policy in an uncertain environment is heavily dependent on the hyper-parameters used to balance exploration with exploitation. In this work, an autonomous learning framework that integrates Bayesian optimization with Gaussian process regression to optimize the hyper-parameters of a reinforcement learning algorithm, is proposed. Also, a bandits-based approach to achieve a balance between computational costs and decreasing uncertainty about the \textit{Q}-values, is presented. A gridworld example is used to highlight how hyper-parameter configurations of a learning algorithm (SARSA) are iteratively improved based on two performance functions.
Maximum Diversity Problem. A Multi-Objective Approach
Authors: Vera Escobar Katherine Dahiana , Lopez-Pires Fabio , Baran Benjamin , Sandoya Fernando
Published: October 2018

The Maximum Diversity (MD) problem is the process of selecting a subset of elements where the diversity among selected elements is maximized. Several diversity measures were already studied in the literature, optimizing the problem considered in a pure mono-objective approach. This work presents for the first time multi-objective approaches for the MD problem, considering the simultaneous optimization of the following five diversity measures: (i) Max-Sum, (ii) Max-Min, (iii) Max-MinSum, (iv) Min-Diff and (v) Min-P-center. Two different optimization models are proposed: (i) Multi-Objective Maximum Diversity (MMD) model, where the number of elements to be selected is defined a-priori, and (ii) Multi-Objective Maximum Average Diversity (MMAD) model, where the number of elements to be selected is also a decision variable. To solve the formulated problems, a Multi-Objective Evolutionary Algorithm (MOEA) is presented. Experimental results demonstrate that the proposed MOEA found good quality solutions, i.e. between 98.85% and 100% of the optimal Pareto front when considering the hypervolume for comparison purposes.
Systematic evaluation of Business Process Management Systems
Authors: Calegari Daniel , Delgado Andrea
Published: October 2018

Selecting a Business Process Management Systems (BPMS) for an organization requires a thorough evaluation of its capabilities considering the whole support of the business process lifecycle and the organizational environment in which the BPMS will be used. In a previous work, we have proposed a methodology for the systematic evaluation of BPMS, ensuring the quality of the results and the repeatability of the evaluation process. The methodology envisions a quantitative and qualitative evaluation regarding the fulfillment of key features that BPMS must provide in the context of a given organization. However, it was mostly focused on required functional and non-technical aspects. In this paper, we present the extension of our methodology with a detailed definition of non-functional aspects to be evaluated, a set of test cases for their evaluation, and the development of a case study as a complimentary qualitative evaluation. We also performed a fine tuning of the methodology based on a comprehensive comparison with other existent methodologies and the provision of tool support. To illustrate the approach, we present results from the evaluation of open source and proprietary BPMS which constitute both a validation and assessment of our proposal and a contribution to knowledge regarding the capacities of selected BPMS technologies.
Poligamia en Marruecos y pensión de viudedad en España. El Tribunal Supremo y el orden público internacional atenuado = Poligamy in Morocco and pension in Spain. The Spanish Supreme Court and the public policy exception
Authors: Valverde Martínez María José , Carrascosa González Javier
Published: October 2018

Resumen: El presente trabajo expone y analiza los criterios de solución empleados por el Tribunal Supremo para dar respuesta a la cuestión de saber si dos mujeres, viudas de un sujeto legalmente casado con ambas en Marruecos, pueden ser beneficiarias de la pensión de viudedad generada por dicho sujeto. El Tribunal Supremo acoge e implementa la tesis del orden público internacional atenuado. Lo hace al mar­gen de todo convenio internacional y de todo precepto legal porque entiende que el orden público atenuado protege los fundamentos jurídicos de la sociedad española y permite, al mismo tiempo, que un matrimonio legalmente celebrado en Marruecos, surta ciertos efectos legales en España. En particular, admite que ambas esposas puedan ser consideradas beneficiarias, a partes iguales, de la pensión de viudedad española.Palabras clave: orden público internacional, pensión de viudedad, poligamia, Derecho internacio­nal privadoAbstract: This paper deals with the criteria used by the Supreme Court of Spain in order to answer the question of whether two women, widows of the same husband, both legally married in Morocco, can be regarded as beneficiaries of the widow’s pension generated by their husband. The Supreme Court of Spain implements a mitigated public policy effect even though no international convention applies to the case. Once guaranteed that the legal foundations of Spanish society are safe, the Spanish Supreme Court activates an attenuated public policy to allow some legal effects of a marriage legally celebrated in Morocco. Among them, the court admits that both wives can be considered beneficiaries, in equal parts, of the Spanish widow’s pension.Keywords: public policy, widow’s pension, polygamy, private international law.
Una lectura crítica de los vínculos familiares a la luz de la Directiva 2003/86/CE y de las normas españolas de extranjería = A critical view to restoring family legal ties in the Council Drective 2003/86/EC and in the Spanish Immigration Llaw

Published: October 2018

Resumen: La salvaguarda del derecho a la vida en familia, tal y como se recoge en los instru­mentos internacionales de Derechos humanos, inspiran las condiciones de ejercicio de la reagrupación familiar. En la tramitación de las autorizaciones de residencia por reagrupación familiar, los Estados miembros cuentan con dos mecanismos que permitirían limitar el acceso al territorio de los miembros de la familia: (1) mediante el establecimiento de condiciones materiales subjetivas y objetivas para la entrada en el territorio (problema típico de derecho de extranjería o migratorio); (2) mediante el control de la validez de los vínculos familiares preexistentes (problema típico del Derecho internacional pri­vado). El examen crítico de la interacción de ambos mecanismos y su análisis a la luz de la Directiva 2003/86/CE y de las normas españolas sobre reagrupación familiar (LO 4/2000 y RD 557/2011) es el objetivo de este trabajo.Palabras clave: reagrupación familiar, nacionales de terceros países, reconocimiento de los víncu­los familiares, límites materiales de las normas de extranjería, interacción de las normas de Derecho in­ternacional privado, Directiva 2003/86/CE, Derecho español de extranjería (LO 4/2000; RD 557/2011).Abstract: One of the fundamental issues to implement legal measures concerning family reunifica­tion in the European Member States is to protect the family unit and respect family life, safeguarded by many instruments of international law. Administratively, in accordance with the integration policies of Member States, two mechanisms can be applied to restrict the potential access of a family member to the new territory. One, through stand still and status quo clauses (typical matters concerning migration law). Two, in international family law, interactions with the complexities of private international law (PIL) are unavoidable, which can be decisive on entry and exiting decisions concerning family regrouping. This paper provides a critical evaluation of both matters in light of the Council Directive 2003/86/CE and the Spanish regulation for family reunification.Keywords: family reunion of third-country nationals, limits to recognize the existence of family ties, restrictive measures, stand still clause, status quo clause; interaction of private international law rules; Directive 2003/86/CE, Spanish Immigration Law.
