Kausalitas Ekspor Indonesia ke Tiongkok dengan Inflasi Indonesia, Suku Bunga Dasar Tiongkok, dan Nilai Tukar Indonesia
Authors: Leonard Teddy Aldwin
Published: March 2018

Tujuan penelitian ini adalah mengetahui hubungan kausalitas antara total nilai ekspor Indonesia ke Tiongkok dengan tingkat suku bunga Tiongkok, tingkat inflasi Indonesia, dan nilai tukar Rupiah Indonesia terhadap Yuan China. Penelitian ini menggunakan uji kausalitas granger dengan variabel total nilai ekspor Indonesia ke Tiongkok, tingkat inflasi Indonesia, tingkat suku bunga dasar Tiongkok, dan nilai tukar Rupiah Indonesia terhadap Yuan China untuk melihat hubungan kausalitas antar variabel. Hasil uji kausalitas granger menunjukkan hasil bahwa total nilai ekspor Indonesia ke Tiongkok memiliki hubungan satu arah dengan variabel tingkat suku bunga Tiongkok dan variabel nilai tukar Rupiah Indonesia terhadap Yuan China, namun tidak terdapat hubungan kausalitas dengan variabel tingkat inflasi Indonesia. Hubungan satu arah antara total nilai ekspor Indonesia ke Tiongkok dengan tingkat suku bunga Tiongkok adalah total nilai ekspor Indonesia ke Tiongkok menyebabkan perubahan tingkat suku bunga Tiongkok, sedangkan hubungan satu arah antara total nilai ekspor Indonesia ke Tiongkok dengan nilai tukar Rupiah Indonesia terhadap Yuan China adalah nilai tukar Rupiah Indonesia terhadap Yuan China menyebabkan perubahan total nilai ekspor Indonesia ke Tiongkok.

The purpose of this study is to know the causality relationship between the total value of Indonesia's exports to Tiongkok with Tiongkok's interest rate, the inflation rate of Indonesia, and the exchange rate of Indonesian Rupiah against the Yuan China. This study uses granger causality test with total variable of Indonesian export value to Tiongkok, Indonesia inflation rate, interest rate of Tiongkok, and Indonesian Rupiah exchange rate to Yuan China to see the relation of causality among variables. Granger causality test results show that the total value of Indonesia's export to Tiongkok has unidirectional relationship with variable of Tiongkok interest rate and variable of Indonesian Rupiah exchange rate to Yuan China, but there is no causality relationship with Indonesian inflation rate variable. The unidirectional relationship between the total value of Indonesia's exports to Tiongkok and the Tiongkok interest rate is the total value of Indonesia's exports to Tiongkok causing a change in the Tiongkok interest rate, while the unidirectional relationship between the total value of Indonesia's exports to Tiongkok and the Indonesian rupiah against the Yuan China is the value The Indonesian rupiah exchange rate against the Yuan China led to a change in the total value of Indonesia's exports to Tiongkok
Party Identification, Voter Attitudes, and Voter Behavior in New Jersey and Pennsylvania, 1980–2012: Real Difference or Election Law Mirage?
Authors: Vike James E.
Published: March 2018

This study examines the extent to which pronounced differences in voter registration statistics between Pennsylvania and New Jersey are truly indicative of significant differences in political attitudes and voter behavior across citizens of these neighboring states. The analysis is based upon an examination of cumulative 1980–2012 American National Election Study (ANES) survey data. Although there is evidence that minor differences in partisan attachments exist, there is no evidence that these differences are manifest in diminished interest, efficacy, polarization levels, participation rates, or straight-ticket voting behavior. The central conclusion of this study is that the elevated tendency of New Jersey voters to register as unaffiliated is less of a marker of greater independent orientations and more of an election law mirage that furthers a myth of mounting citizen independence from partisan affiliations. Furthermore, these findings support the conclusion that a follow-up methodology for determining true partisan attachments among ANES respondents is a more accurate predictor of partisan attitudes and behavior than methods relying upon an initial probe of self-identified partisanship or statewide voter registration statistics.

Published: March 2018

Introduction: Vitamin D deficiency has become quite prevalent and is known to cause a great many diseases. Numerous studies have investigated the association between vitamin D deficiency and gestational diabetes, and the results are somewhat contradictory. The present study deals with the relationship between the vitamin D deficiency and gestational diabetes.
Methods: Two researchers made use of MeSH, Scopus, PubMed database, Science Direct, the Cochrane Library, the Web of Science, CINAHL, and Google Scholar search engines to identify qualified studies and articles carried out and published before August 2017 and reported the risk of gestational diabetes developing as a result of vitamin D deficiency. The association between the two conditions was measured using odds ratios (ORs) with 95% confidence intervals (CIs). Funnel plots, Egger’s, and Begg’s tests were also used to assess publication bias. All analysis was done by STATA (version 11.2).
Results: Twenty-nine eligible studies with a total of 14,497 participants were included in the final analysis. Overall, maternal vitamin D insufficiency was significantly associated with a greater risk of gestational diabetes (OR = 1.15; 95% CI, 1.00-1.30; p<0.001). Serum 25OHD was significantly lower in participants with gestational diabetes mellitus than in those with natural glucose tolerance (−29.7 nmol/L, 95% CI, −36.6 to −22.8; p=0.000).
Conclusion: According to the current meta-analysis results, vitamin D deficiency is correlated with the risk of gestational diabetes development.
LA CONSTRUCCIÓN DEL ESTADO LOCAL EN COLOMBIA
Authors: García Villegas Mauricio , Revelo Rebolledo Javier
Published: March 2018

La violencia ocurrida después de que las FARC entregaran las armas en varias regiones del país es una prueba de que la construcción de paz no solo depende de la implementación de los acuerdos de paz, sino también del fortalecimiento del Estado local, lo cual, a su turno, debe reconocer las particularidades de las regiones que han sido gravemente afectadas por el conflicto armado. De esto no se sigue necesariamente que cada municipio o vereda deba tener una estrategia diferente y única. El objetivo de este artículo es, con base en el estudio detallado de cinco municipios, proponer herramientas de tipo teórico que faciliten encontrar un balance entre una ley universal que desestima las singularidades del contexto local y una normatividad local poco atenta a las exigencias de coherencia general del Estado.
REDES DE CORRUPCIÓN POLÍTICA: UNA REVISIÓN PARA EL CASO COLOMBIANO
Authors: Gómez Calderón Diego Javier
Published: March 2018

La corrupción es un fenómeno característico de las sociedades humanas, que se presenta tanto en países en desarrollo como en países desarrollados. En Colombia, el fenómeno de la corrupción política no solo se genera y reproduce por la debilidad institucional del país, sino también por condiciones sociopolíticas y culturales, como el clientelismo y el narcotráfico. Este artículo indaga, desde la economía, el fenómeno de la corrupción política, partiendo del análisis pionero del Public Choice e incorporando un análisis de redes para caracterizar la complejidad estructural que definen los procesos de corrupción política, clientelismo y favorecimientos judiciales en Colombia.
Problemas en la adopción de modelos de gestión de servicios de tecnologías de información. Una revisión sistemática de la literatura
Authors: Melendez-Llave Karin Ana , Dávila-Ramón Abraham Eliseo
Published: March 2018

Ante el creciente uso de las tecnologías de información se han desarrollado modelos de gestión de servicios de tecnología de información (GSTI) con la finalidad que las organizaciones puedan ofrecer servicios de manera eficaz y con mayor nivel de calidad. Sin embargo, el cumplimiento de estos modelos no ha representado un trabajo fácil y las organizaciones han encontrado diversos problemas logrando adopciones parciales. El objetivo del estudio es analizar los problemas que las organizaciones han tenido en la adopción de un modelo de GSTI y para ello se ha realizado una revisión sistemática de la literatura. En la revisión se encontró que sólo algunos procesos fueron adoptados como parte de la implementación de los modelos y del análisis realizado podemos mencionar que las dificultades más recurrentes son: la falta de compromiso de la alta dirección y la falta de conocimiento sobre los modelos de GSTI y sus beneficios.
Ensamblado de fragmentos de ADN utilizando un novedoso algoritmo de luciérnaga en GPU
Authors: Vidal Pablo Javier , Olivera Ana Carolina
Published: March 2018

El problema de ensamblado de fragmentos de cadenas de ácido desoxirribonucleico (Deoxyribonucleic Acid Fragment Assembly Problem, DNA-FAP) consiste en la reconstrucción de cadenas de ADN desde un conjunto de fragmentos tomados aleatoriamente. El DNA-FAP ha sido resuelto por diferentes autores utilizando distintos enfoques. Aunque se obtienen buenos resultados, el tiempo computacional asociado es alto. El algoritmo de luciérnaga (Firefly Algorithm, FA) es un modelo bioinspirado basado en el comportamiento de las luciérnagas. Al ser un algoritmo bioinspirado poblacional es posible generar un modelo paralelo del mismo sobre Unidades de Procesamiento Gráfico (Graphics Processing Units, GPU). En este trabajo un algoritmo de luciérnaga es diseñado especialmente para ser ejecutado sobre una arquitectura GPU de manera tal de acelerar el proceso computacional buscando resolver el DNA-FAP. A través de diferentes experimentos se demuestra la eficiencia computacional y la calidad de los resultados obtenidos.
Atenuación de efectos pendulares en grúas-torre usando control por rechazo activo de perturbaciones en tiempo discreto con observador resonante
Authors: Coral-Enriquez Horacio , Pulido-Guerrero Santiago
Published: March 2018

En este artículo, se propone un esquema de control en tiempo discreto basado en el enfoque del rechazo activo de perturbaciones (ADR) para abordar el problema de control de oscilaciones en la carga de grúas-torre sujetas a incertidumbres paramétricas y perturbaciones externas. El esquema de control propuesto usa un observador extendido que incorpora un modelo interno resonante diseñado para mejorar la estimación de variables de estado y perturbaciones, en especial las provenientes de la oscilación de la carga. La ley de control se diseña para rechazar las perturbaciones en línea y acomodar la dinámica de lazo cerrado. La propuesta de control se valida experimentalmente en una grúa-torre a escala, y es comparado con un PI-vectorial y otro control basado en el enfoque ADR. Los resultados experimentales muestran que el esquema propuesto presenta mejor desempeño para reducir las oscilaciones en la carga y exhibe mejoras sustanciales en el rechazo de perturbaciones.

Published: March 2018

Los sistemas para compartir bicicletas (BSS) y programas para compartir bicicletas (BSP) han sido implementados alrededor del mundo en la última década por sus beneficios y con el fin de cambiar el paradigma que el carro no debería ser el principal modo de transporte de las áreas urbanas. Por esta razón, uno de los elementos más importantes que necesita ser bien planeada es la localización de las estaciones de bicicletas. Esta investigación evalúa la localización de las estaciones de bicicleta de un BSS en una ciudad pequeña de Colombia, basado en la localización de los usuarios del sistema. Adicionalmente, se presentan dos propuestas para obtener un mejor entendimiento de cómo el BSP podría ser bien planeado y consolidado. Los resultados fueron obtenidos con un modelo de localización-asignación que asigna cada usuario que está dentro de un valor de impedancia para cada estación.

Published: March 2018

La selección de parámetros óptimos de corte es un aspecto esencial en la planificación de cualquier proceso de maquinado, principalmente cuando la sostenibilidad es un objetivo primordial. En este trabajo se presenta una optimización multiobjetivo dirigida a producciones sostenibles, con el fin de seleccionar los parámetros de corte óptimos (velocidad, avance y la profundidad de corte) en operaciones de cilindrado multipasada. Como funciones objetivos del proceso fueron considerados: el aspecto económico y el medioambiental, los cuales son pilares representativos de la sostenibilidad. Requerimientos técnicos, tales como: la potencia de corte, las fuerzas y la rugosidad superficial fueron considerados como restricciones. La optimización se llevó a cabo mediante un enfoque a posteriori; donde se obtuvo un conjunto de soluciones no dominadas (también conocidas como frontera de Pareto) que permitió la selección de la combinación más viable de objetivos para las condiciones específicas del taller. Para la optimización se emplearon dos técnicas de gradiente libre: algoritmo genético sin ordenamiento y enjambre de partículas. Se desarrolló un estudio de caso para evaluar el ajuste y la eficiencia de las técnicas propuestas. Los resultados obtenidos mostraron un mejor rendimiento del algoritmo genético usado, en cuanto a: costo computacional y calidad de la frontera de Pareto obtenida. El método propuesto demostró ser muy conveniente para la optimización sostenible del proceso de torneado, a través de una evaluación simultánea de aspectos económicos y ambientales.
Uso de la entonación para identificar cuándo usar la tilde diacrítica en el reconocimiento automático del habla
Authors: Bolaños Araya Constantino , Camacho Lozano Arturo , Del Río Urrutia Ximena
Published: March 2018

Los métodos y técnicas computacionales de reconocimiento automático del habla son herramientas que poco a poco se incorporan en la vida cotidiana. Una de sus principales ventajas es que permiten a las personas registrar texto rápidamente usando uno de los medios que mejor saben usar: su voz. Desafortunadamente, esta tecnología aún no es perfecta y los errores de transcripción son comunes. En el idioma español, uno de los errores más comunes de esta tecnología, es la omisión de la tilde diacrítica. Esto se debe en gran medida a que las técnicas utilizadas en el reconocimiento automático del habla ignoran el acento, es decir, la sílaba acentuada de una palabra, que en el idioma español no tiene un patrón fijo, como en otras lenguas. Esto se debe a que estas técnicas fueron desarrolladas inicialmente para el idioma inglés, en el cual no hay tildes y el acento juega un papel menor en la diferenciación de las palabras. Nuestra propuesta es incorporar el análisis del tono en el reconocimiento automático del habla para mejorar la marcación de tildes diacríticas en un texto. Ensayos previos han mostrado que la creencia extendida de que la sílaba acentuada es siempre la más fuerte (la más intensa) es falsa. Por tanto, la intensidad, por sí sola, no es un buen indicador de la ubicación o presencia de la sílaba acentuada que debe ser tildada, sino que el tono también ha de ser considerado. En esta investigación se muestra que el tono puede ayudar a determinar la sílaba que debe ser tildada según nuestra convención gráfica.
Measuring the impact of collocational knowledge on sentence parsing
Authors: Wehrli Eric
Published: March 2018

In this paper we focus on collocations, which have been studied in computational linguistics since they constitute a key factor when processing natural languages. For instance, they usually represent a challenge in automatic translation because the association of two terms is not easily computed. We proposed that the parser should be provided with a lexical database in order to make more effective the identification of collocations during the parsing process. We assessed this claim by using a corpus of 6’000 sentences retrieved from the British magazine The Economist Espresso. The corpus was parsed twice, first with the collocation detection component turned on and then with it turned off, and to make the comparison the Fips tagger was used. The results showed an improvement of the quality when the parser has access to collocation knowledge.

Note à un passage d’Achille Tatios
Authors: Szepessy Tibor
Published: March 2018

The paper deals with the expression πρὸ τοῦ πολέμ0υ to be found at the locus indicated in the title, which is either amended or regarded with incomprehension by the editors of Achilles Tatius. However, the expression cannot originate from him, as otherwise one would have to suppose that the author of the novel directly opposes the plot he had created. It is more likely that the expression may originally have been a marginal remark that only entered the text in the course of its transmission. In view of this, the expression needs to be deleted, not amended; in which case the problematic nature of the locus immediately disappears.
“Pannonia terra creat, tumulat italia tellus” •
Authors: Székely Melinda
Published: March 2018

The role of Pannonian soldiers in the guards is traceable from the 2nd century while their number and significance had grown considerably both in the units of praetoriani and equites singulares from the rule of Septimius Severus. Inscriptional sources mention that from time to time their families, wives and kin moved to Rome with the guardsmen. On their gravestone reliefs, one can find themes both from their homelands, traditions and from new Roman erudition. The decades spent serving the Emperor in Rome could mean social advancement, gaining fortune and recognition while the best ones could become military officers. After retiring from service, they could play an important role in the life of the province and in the Romanization of Pannonia as well.
The nature of astrology in Janus Pannonius’ works composed in Hungary
Authors: Orbán Áron
Published: March 2018

Astrology plays a significant role in the Neo-Latin poetry of Janus Pannonius (1434–1472), the most renowned humanist of Hungary. The article investigates the various forms of astrological ideas in that part of his oeuvre where a specific interest in astrological topics can be witnessed: the works concerned are letters, elegies and epigrams composed in Hungary. Previous research into this topic has neglected to face the problem of the heterogeneity of astrology and to explore in detail the biographicalhistorical context, and some scholars have argued that Janus deeply believed in astrology. Instead, I will conclude that the appearance of astrological ideas can simply be explained by biographical, literary historical, intellectual historical factors. The argument concerns not only one particular person but also the intellectual life of mid-fifteenth century Hungary, and the habits of the Renaissance mind in general.
István Szántó (Arator) e la fondazione del Collegium Hungaricum della Compagnia di Gesù a Roma
Authors: Lázár István Dávid
Published: March 2018

The Jesuit, István Szántó (Arator), who was a Hungarian father-confessor in Rome in the jubilee year of 1575, was engaged in establishing an independent Collegium Hungaricum to improve clerical training in the Eternal City in the second half of the 16th century. First, he succeeded since he managed to make the pope establish the Collegium despite the strong resistance from everywhere around. However, after a few months the pope unified the Collegium Hungaricum with the Collegium Germanicum because there was not a sufficient number of students from Hungary in Rome. Although the efforts of Szántó ended in failure, they had important effects on Hungarian Catholicism. For example, places were to provide for twelve Hungarian students in the united Collegium in the following centuries. In this paper, a brief review can be found about the writings of Szántó for the sake of the foundation of the Collegium Hungaricum.
Genres of literary representation: Occasional poems to Archbishop József Batthyány
Authors: Báthory Orsolya
Published: March 2018

The Neo-Latin occasional poetry is a rarely explored field of Hungarian literary history. József Batthyány was addressed with almost 160 — mostly printed, but some in manuscript — works of art, poems and speeches during his 40-year service as high priest. The main idea of these was the overwhelmingly excessive appraisal of his pastoral and personal merits. The apropos of the works were the Archbishop-Cardinal’s birth and name days, his investiture into ecclesiastic positions and his diocese visits. In this study I examine the poems from the point of view of their genre, including the theoretical background of some 18th-century poetics, among which the Palaestra by Jacob Masen undoubtedly had the biggest influence on the contemporaneous poetic approach.

PEMANFAATAN DATA SATELIT OSEANOGRAFI UNTUK MEMPREDIKSI DAERAH PENANGKAPAN IKAN LEMURU BERBASIS RANTAI MAKANAN DAN PENDEKATAN STATISTIK GAM
Authors: Susilo Eko , Arief Wibawa Teja
Published: March 2018

Ikan lemuru di Selat Bali umumnya ditangkap menggunakan pukat cincin (purse seine) atau dalam istilah lokal dikenal dengan ‘slerek’ yang dipimpin oleh Juru Panggung. Penentuan daerah penangkapan yang masih mengandalkan intuisi juru panggung berdampak pada penggunaan bahan bakar yang tidak efesien. Perlu adanya inovasi teknologi guna meningkatkan efesiensi operasi penangkapan ikan di Selat Bali. Salah satunya melalui pemberian informasi dugaan daerah penangkapan ikan berbasis teknologi inderaja dan pendekatan rantai makanan. Penelitian ini bertujuan memprediksi kelimpahan zooplankton, sebagai makanan utama ikan lemuru, melalui pendekatan statistik Generalized Additive Model (GAM) berdasarkan data-sata satelit oseanografi. Variabel respon berupa data kelimpahan zooplankton di perairan Selat Bali yang diukur selama periode bulan Maret – Agustus (2011-2013). Sedangkan variabel prediksi berupa data harian variabel oseanografi yang diukur oleh satelit Aqua MODIS pada hari yang sama dengan pengambilan sampel plankton. Sebanyak 7 model kelimpahan zooplankton telah dihasilkan melalui pendekatan statistik GAM berdasarkan parameter oseanografi utama yang mempengaruhi ketersediaan makanan lemuru. Hasil penelitian menunjukkan persamaan GAM yang terbaik merupakan kombinasi antara variabel suhu permukaan laut (SST), konsentrasi klorofil-a (SSC) dan Photosynthetically Available Radiation (PAR) dengan nilai deviasi terbesar (75,3%) dan Akaike’s Information Criterion terkecil (160,197). Variabel SST dan PAR memiliki tingkat signifikansi yang lebih tinggi dari pada SSC. Kelimpahan zooplankton yang tinggi ditemui pada kisaran SST antara 25-26oC, SSC antara 0,5–0,6 mg/m3, dan PAR antara 40-45 einsten/m2/day. Nilai korelasi antara hasil prediksi kelimpahan zooplankton dan hasil tangkapan ikan lemuru sebesar 59,57%.

Authors: Nguyen Van-Trang , Nguyen Danh-Truong , Le Minh-Quy
Published: March 2018

In the present work, the uniaxial tensile tests of 3 pairs black phosphorene nanotubes are simulated by molecular dynamics finite element method with Stillinger-Weber potential. Each pair contains an armchair black phosphorene nanotube and a zigzag one, which have approximately equal diameters. Three armchair black phosphorene nanotubes, namely (0, 15), (0, 19) and (0, 21); and three zigzag black phosphorene nanotubes, namely (20, 0), (26, 0) and (28, 0), are considered. We found that the Young's modulus of these tubes increases when their diameter increases. Their fracture stress and fracture strain are also investigated.

Published: March 2018

Polymer nanocomposites are relatively new class of materials. Incorporation of inorganic nanoparticles into a polymer matrix can significantly influence the properties of the matrix. The obtained composite might exhibit improved thermal, mechanical and optical properties. In this study, the CeO2–TiO2 nanoparticles have been applied to modify properties of polyurethane matrix in order to improve the ultra‐violet (UV) absorption property of polyurethane thin films. The interdependence of mechanical properties, UV absorption property and the dispersed concentration of CeO2‐TiO2 nanoparticles were investigated. Results showed that, the mechanical properties of polyurethane thin films coating CeO2‐TiO2 nanoparticles in testing conditions such as film‐forming ability, bonded coating and hardness, modulus, adhesion, impact resistance almost unaffected when the containing CeO2‐TiO2 nanoparticles ≤2 %. The survey sample was qualified; the scratches do not change the composition CeO2‐TiO2 ≤ 1 %. Samples containing 0.2 % CeO2‐TiO2 nanoparticles showed the best resistance to discoloration and most influential causes less of gloss paint. The aim of the present work is to investigate the mechanical properties and UV absorption property of CeO2‐TiO2 nanoparticles/urethane thin films. It is expected that the CeO2‐TiO2 nanoparticles would enhance the UV absorption properties of resulting CeO2‐TiO2 nanoparticles/urethane thin films.

WIRED FOR SOCIAL INTERACTION: WHAT AN INTERDISCIPLINARY APPROACH FROM NEUROBIOLOGY, EVOLUTIONARY BIOLOGY, AND SOCIAL EDUCATION WORK CAN TEACH US ABOUT PSYCHOLOGICAL TRAUMA
Authors: Sarto-Jackson Isabella
Published: March 2018

The human brain is equipped with physiological, neural, and cognitive capacities that enable it to respond flexibly to ever-changing natural and social conditions. This capacity of the brain to reorganize itself, called neuroplasticity, is particularly marked in childhood. The high malleability of the brain at this stage provides the basis for wide-ranging learning, but leaves it vulnerable to negative environmental and social factors. Neuroplastic events that occur in response to abusive or neglecting environments can strongly interfere with the adaptive shaping of neural pathways between the prefrontal cortex and the limbic system, compromising judgment and self-control. Traumatic experiences during development can also have other effects on brain plasticity that are mediated by epigenetic mechanisms, and these effects can impair the developing oxytocin system, adversely affecting attachment and bonding. Mature individuals seek out niches that match the internal mental structures shaped during their early years, and will even alter the environment to make it match the internal structures. In the case of those who suffered childhood abuse, this can lead to maltreatment of the next generation. Addressing the societal challenge of child abuse and maltreatment requires broad interdisciplinary endeavors, uniting neuroscientists and social education workers to break the vicious circle.

In order to foster interactive discussions with other countries, this paper offers an overview of residential care for children in Japan and its ongoing development. Japan still relies especially heavily on the residential care system; this is due to the past process of development more than to traditional Japanese culture. The period from the post World War II era to the present is briefly described, including the rapid growth in the number of institutions before 1960, the rather stable period before 1990, the revision of the Child Welfare Act in 1997 permitting the privatization of institutions, and the movement towards problematizing child abuse in the mid 1990s, after which residential institutions were designated as the last resort for maltreated young people. In the present situation, smaller institutions and a foster care system are strongly promoted in accordance with international guidelines for alternative care and the recent governmental guideline based on the Child Rearing Vision of 2010 and the Child Welfare Act of 2016. The task of present Japanese residential care institutions is to realize a family-like environment and a better placement strategy, collaborate more with specialists to improve the standard of care, function in the community as centers for the care of children in need, and expand their care work for young adults and care leavers. The paper concludes by stressing the need for more international exchange among individuals and groups working in Japanese residential care.

Objetivo: analisar as estratégias adotadas por mulheres frente à baixa resolutividade em área de cobertura da Estratégia Saúde da Família. Método: estudo de abordagem qualitativa, tendo a integralidade como categoria analí- tica. Foram entrevistadas doze mulheres em idade reprodutiva e cadastradas em duas Unidades de Saúde da Família. O material empírico foi analisado pela técnica de análise de discurso. Resultados: a busca por serviços de maior complexidade constitui a principal estratégia adotada por mulheres para atendimento de suas demandas na ausência de respostas da Atenção Básica. Incorporam essa rede como referência diante da falta de infraestrutura da rede básica para efetivar o seu papel e a Estratégia Saúde da Família passa a ser lugar de procura eventual. Conclusões: diante da inoperância da Estratégia Saúde da Família, a rede especializada passa a ser primeira escolha das mulheres, numa inversão de papéis, que fortalece o modelo médico assistencial curativo, contraria as diretrizes do Sistema Único de Saúde e nega a integralidade.

Being a largepart of naturally occurring language, collocations and other types of multiwordunits (e.g., idioms, phrasal verbs, lexical bundles) have been identified as importantaspects of L2 proficiency that need to be promoted through language instruction.However, while in recent years the field of applied linguistics has witnessedan impressive rise in the number of studies exploring the process of learning andusing L2 collocations, there is still little consensus as to the most effective waysof enhancing this kind of knowledge. The aim of this article is to review the literaturein this area, highlight the main findings pertaining to teaching English as asecond (ESL) and foreign (EFL) learners, and point to future research directions.L’objectif de cet article est de présenter et résumer les résultats principaux derecherche dans le domaine de l’apprentissage et l’enseignement des expressions figéesen L2. Constituant une partie importante d’une langue naturelle, les expressionsfigées et d’autres types d’unités composées (p. ex. expressions idiomatiques,verbes à particule) sont des aspects importants de la compétence en L2 que l’enseignementde la langue doit promouvoir. Toutefois, si le nombre d’études portantsur l’apprentissage et l’emploi des expressions figées en L2 a augmenté de façonimportante dans le domaine de la linguistique appliquée récemment, un faibleconsensus existe quant aux moyens qui sont les plus efficaces pour favoriser cesconnaissances. L’objectif de cet article est d’examiner la littérature de ce domaine,souligner les résultats principaux relatifs à l’enseignement de l’anglais langueseconde et l’anglais langue étrangère, et indiquer des pistes de recherches futures.
