Grade one teachers methods of teaching pre-reading skills to second language learners in an inner-city school

Morgan, Leanne January 2017 (has links)
Education is a fundamental precondition for progress and growth in South Africa (Spaull, 2011, p. 1). Literacy opens the doors to better livelihoods, improved health and expanded opportunity (UNESCO, 2011). Illiteracy is a serious constraint to improving education standards in South Africa. Prominent research studies stress the low levels of reading ability across the country. At the onset of Grade One, pre-reading skills are taught. Pre-reading skills are foundational skills and essential for later reading success. Teachers in English Second Language environments face the daunting challenge of teaching learners to read in a foreign language. This qualitative research study, which was conducted at a low-fee private school in Pretoria Central Business district, aimed to explore the methods that educators were using to teach second language English Learners (ESL) pre-reading skills. Data collected from semi-structured interviews, lesson observations and document analysis revealed that educators had a limited theoretical knowledge of pre-reading skills due to a lack of tertiary education and curriculum training. Numerous methods of teaching pre-reading skills were identified during pre-reading lesson observations. The synthetic phonics approach, multisensory teaching, using dramatization and subtractive bilingualism were methods of instruction used to develop phonemic awareness and English oral language competency. The study highlighted the numerous challenges faced by ESL teaching working in a low-socioeconomic environment and the ways in which the teachers overcame these challenges. Based on this study’s results, recommendations are provided to enhance the teaching of pre-reading skills to ESL learners. / Dissertation (MEd)--University of Pretoria, 2017. / Educational Psychology / MEd / Unrestricted

Ap4A-RNA v IgE aktivovaných žírných buňkách / Ap4A-RNA in IgE activated mast cells

Potužník, Jiří František January 2021 (has links)
Mast cells are tissue resident members of the immune system. They have a wide range of functions and receptors including the FcεRI receptor, which gets activated by binding to IgE bound to an antigen. When the cells are activated in this manner, a process termed the LysRS- Ap4A-MITF signalling pathway occurs, resulting in the translocation of the Lys tRNA synthetase into the nucleus and an activation of its moonlighting activity - the production of diadenosine tetraphosphate (Ap4A). Ap4A is a dinucleoside polyphosphate, a type of ubiquitous molecule present in all domains of life. They are made up of two nucleosides joined together by a 5' to 5' phosphodiester bridge of variable lengths. Recently, these molecules have been shown to serve as non-canonical initiating nucleotides during bacterial transcription, where they function as 5' RNA caps, similar to the well-known 7- methylguanosine eukaryotic mRNA cap. In this thesis, I present proof of existence of Ap 4A capped RNA in mast cells, a previously unknown 5' RNA structure in eukaryotic cells, and I attempt to pinpoint its role in the activation of these cells and in the wider context of mast cell mediated immune response. Keywords: mast cells, RNA caps, Dinucleoside polyphosphates, Ap 4A, RNA modification, IgE, FcεRI receptor, Lysine tRNA synthetase

Helping in the Workplace: A Social Cognitive Perspective

Kalanick, Julie Lynn 13 May 2008 (has links)
This study employed an experimental design intended to be an analog to the workplace to examine a person by situation interactive effect on OCBs, which were evaluated as prosocial behaviors. This study also sought to provide initial empirical support for the two-stage social cognitive model of OCBs proposed by Hauenstein and Kalanick (2008). Participants were 194 undergraduates. The study was a 2 (Helpfulness) by 2 (Fairness) design. After completing distracter tasks 1 and 2, participants received either a helpfulness prime or a control prime (task 3). Participants then either experienced either a fair manipulation or an unfair manipulation. Results indicated a distinction between the decision to help and helping effort, which has not been thoroughly examined in literature on OCBs. Results revealed main effects for the helpfulness prime and fairness manipulation on the decision to engage in helping. The nature of these effects was that participants helped more when they were primed with helpfulness and when they experienced fairness. However, once helping commenced, there was an interactive effect between helpfulness and fairness such that the helpfulness prime had a stronger effect on participants treated unfairly. Implications for future research on OCBs are discussed. / Ph. D.

Magagula, Sihle Wendy. January 2016 (has links)
A research report submitted to the Faculty of Management, University of the Witwatersrand, in 25% fulfilment of the requirements for the degree of Master of Management (in the field of Public and Development Management) 2015. / The purpose of the study was to explore the township schools foundation phase teachers' experiences in the implementation of CAPS with regard to curriculum implementation and how their knowledge and experiences influence the implementation of the curriculum. The literature review provides insights into the current practices regarding CAPS in the foundation phase in South African primary schools comparatively throughout the world. A qualitative case study research was adopted for this study and semistructured interviews. The findings highlight that although teachers experienced challenges in implementing CAPS, they acknowledge the benefits of previous workshops. The article recommends that curriculum designers and the Department of Education need to urgently review CAPS. It has been emphasised that teachers need to be actively involved during the review process. Amongst all the requirements for curriculum implementation, teachers need to be constantly monitored and supported to ensure the quality of teaching and learning. / AC2016

Análise de blocos de concreto armado sobre duas estacas com cálice totalmente embutido mediante presença de viga de travamento / Analysis of two pile caps reinforced concrete with embedded socket by presence of locking beam

Barros, Rodrigo 22 May 2009 (has links)
Esta pesquisa estuda o comportamento de blocos de concreto armado sobre duas estacas com cálice totalmente embutido, utilizado na ligação pilar-fundação de estruturas de concreto pré-moldado. Particularmente, foi avaliado o efeito que a viga de travamento provoca no bloco quando apoiada nas paredes laterais do cálice. Foi desenvolvida análise numérica tridimensional utilizando programa baseado no método dos elementos finitos (MEF), na qual foi considerada a não-linearidade física dos materiais. Para avaliação do programa adotado, realizou-se análise comparativa de resultados experimentais e numéricos obtidos por meio de outro programa. Nos blocos estudados variou-se a espessura e o tipo de conformação das paredes do cálice, o ângulo de inclinação da biela e a intensidade das ações na viga de travamento. Os resultados indicam que a presença da viga de travamento não altera de modo significativo o comportamento do bloco, e que a parede do cálice é capaz de transferir a força proveniente da viga em direção às estacas de modo eficaz. Por meio das tensões nas barras da armadura principal, foi possível obter a força no tirante e o ângulo de inclinação da biela antes da ruína dos modelos. Constatou-se que os ângulos apresentaram maior inclinação do que as utilizadas no dimensionamento, que por sua vez foi feito baseado nos modelos de bielas e tirantes. / The present research studies the behavior of two pile caps reinforced concrete with embedded socked used in connections of pre-cast concrete structures. It was particularly evaluated the effect provoked by the locking beam on the pile-caps when supported by the socket lateral walls. Three-dimensional numerical analyses using software based on finite element method (FEM) were developed considering the nonlinear physical behavior of the material. To evaluate the adopted software, a comparative analysis was made using numerical and experimental results obtained from other software. In the pile caps studied, it was noticed a variation in the wall thickness, socket interface, strut angle inclination and action on beam. The results show that the presence of beam does not change significantly the pile caps behavior and that the socket wall is able to transfer effectively the force from the beam to the pile caps. By the tensions on the bars of longitudinal reinforcement, it was possible to obtain the force on the tie and the strut angle inclination before the collapse of models. It was found that the angles present more inclinations than those used in the design, which was made based on strut and tie model.

Análise do comportamento de blocos sobre quatro estacas com cálice embutido / Analysis of the behavior of four-pile caps with embedded socket

Marek Filho, Carlos Antônio 19 August 2010 (has links)
A racionalização e a industrialização da construção civil têm promovido o sistema construtivo baseado em elementos de concretos pré-moldados. O comportamento das ligações entre os elementos pré-moldados constitui uma das principais preocupações dos projetistas, sendo as ligações entre a superestrutura e as fundações determinantes na estabilidade e na distribuição de esforços solicitantes da estrutura. O comportamento de blocos sobre estacas com ligações para pilares pré-moldados possui particularidades em razão do diferente mecanismo de transferência de forças do pilar para o bloco mediante a ligação. Neste trabalho é estudado o comportamento de blocos de fundação apoiados sobre quatro estacas com cálice totalmente embutido para ligação com pilar pré-moldado. O estudo baseou-se em análise numérica não-linear de modelos tridimensionais considerando a fissuração do concreto, a presença de armadura e a interface de ligação. O comportamento de blocos com pilares submetidos à força vertical centrada e excêntrica foi descrito em termos de força última, panorama de fissuração, fluxo de tensões principais e tensões nas armaduras do bloco. Os resultados indicam a ocorrência de transferência de esforços do pilar para a fundação a partir das paredes do cálice de interface lisa, entretanto com intensidade insuficiente para a formação de bielas de compressão, e o risco da ocorrência de punção em blocos onde os pilares são ligados por cálices de paredes lisas. / The rationalization and the industrialization of the civil constructions have stimulated the construction process based on precast elements. One of the main designer\'s worries is about the behavior of the joints between precast elements, and the joints between superstructure and the foundations which are determinant in the construction stability and behavior of elements. In reason of the mechanism of transference of the forces from column to pile-cap by socket connections, the behavior of pile-caps with joints for precast columns has some specificity. The behavior of four-pile caps with embedded socket for precast columns joints is studied in this research. The study is based in nonlinear numerical analysis of three dimensional models considering the cracking in concrete, the reinforcement and the joint interface. The behavior of pile caps under centered and eccentric vertical force is described by ultimate force, cracking patterns, principal stresses flow and reinforcements strains. The results suggests that occurs the transfer of forces from column to the pile cap in the socket walls with smooth interface, however the intensity is not enough to form the struts, and the risk of development of punching shear in pile caps which columns are connected by smooth interface socket walls.

Diagnóstico situacional e propostas de intervenções baseadas em evidências para um CAPS AD III do Distrito Federal

Botelho, Isabela Borges January 2017 (has links)
As demandas em saúde mental, incluindo o uso de drogas, exigem constantes atualizações dos Centros de Atenção Psicossocial Álcool e outras Drogas (CAPS AD). Desta forma, o objetivo deste estudo foi conhecer as estratégias utilizadas na assistência prestada aos usuários de álcool e outras drogas de um CAPS AD III no Distrito Federal e as possibilidades de aplicação do enfoque da saúde baseada em evidências. Foi realizado em duas etapas. A primeira etapa tratou-se de uma pesquisa qualitativa, do tipo Estudo de Caso, no qual foi realizado um diagnóstico situacional. A coleta dos dados deu-se através de três fontes de informação: entrevista semi-estruturada com os profissionais, com questões abertas sobre os atendimentos individuais, acolhimentos e grupos terapêuticos; observação participante e análise documental. Foram entrevistados 21 servidores da equipe técnica. A média do tempo de experiência na área em questão foi de 4,4 anos. O CAPS localiza-se em uma região de uso significativo de drogas. Dispõem de 22 grupos/oficina. Das atividades desenvolvidas, seis apresentam um público significativo, porém são coordenadas apenas por um profissional. Portanto, em períodos de férias e licenças do servidor, as atividades são interrompidas. Observado que algumas atividades não seguem uma estrutura ou manual, sendo realizadas de acordo com a formação profissional do servidor. Foi relatado também que a falta de recursos materiais para realização dos grupos e oficinas, telefone, internet, prontuário eletrônico inviabiliza e/ou dificulta o andamento dos atendimentos e articulações em rede. Além da rede de abrangência do CAPS ser extensa, o número de abrigos (rede social) ainda é escasso o que, em conjunto com a dificuldade econômica dos pacientes, os impede de terem um maior acesso ao serviço. Outro problema relatado é a desmotivação dos servidores e falta de supervisão adequada. Na segunda etapa, foi realizado uma pesquisa bibliográfica baseado em evidência identificando as técnicas de intervenção mais efetivas e eficazes para o tratamento de pacientes em uso de SPA, que ainda não são disponibilizados no CAPS e são passíveis de serem implementadas no serviço. Aquelas que já são utilizadas foi realizado uma comparação com os estudos baseados em evidência a fim de verificar o que poderia ser melhorado. As técnicas foram descritas conforme público (adultos, adolescentes, família). Conclui-se que na estrutura de um CAPS AD pode-se vislumbrar mudanças nas práticas assistenciais realizadas e novas práticas a serem inseridas através dos avanços obtidos nas técnicas de tratamento baseadas em evidências. / Demands on mental health, including drug use, require constant updates from the Centers for Psychosocial Care Alcohol and Other Drugs (CAPS AD). This way, the objective of this study was to know the strategies used in the assistance provided to users of alcohol and other drugs of a CAPS AD III in the Federal District and the possibilities of applying the evidence-based approach to health. It was carried out in two stages: the first stage was a qualitative research of the Case Study type, in which a situational diagnosis was made. The data were collected through three sources of information: semi-structured interviews with professionals with open-ended questions about individual care, nursing and therapeutic groups; participant observation and documentary analysis. Twenty one technical staff were interviewed. The average experience time in the area in question was 4.4 years. CAPS is located in a region of significant drug use. They have 22 groups / workshop. From the activities developed, six have a significant audience, but are conducted only by one professional. Therefore, during vacation periods and server licenses, activities are stopped. Note that some activities do not follow a structure or manual, being carried out according to the professional training of the server. It was also reported that the lack of material resources to carry out the groups and workshops, telephone, internet, electronic medical records makes it difficult and / or makes difficult the progress of the consultations and networking. In addition to the extensive CAPS network, the number of shelters (social network) is still scarce summing up the economic difficulty of the patients prevent them from having greater access to the service. Another problem reported is server demotivation and lack of proper supervision. In the second stage, an evidence-based bibliographic research was carried out, identifying the most effective intervention techniques for the treatment of patients using SPA, which are not yet available in CAPS and are likely to be implemented in the service. Those ones which are already used have been compared with evidence-based studies in order to verify what could be improved. The techniques were described as public (adults, adolescents, family). It is concluded that in the structure of a CAPS AD, it can be glimpsed changes in the care practices performed and also new practices to be inserted through the advances obtained in the treatment techniques using evidence based health as a guideline.

Perfil dos usuários de substâncias psicoativas em um centro de atenção psicossocial de um município de pequeno porte no Estado do Rio Grande do Sul

Lauermann, Graciela Seibt Licks January 2017 (has links)
Esta pesquisa teve como objetivo conhecer o perfil dos usuários de substâncias psicoativas do CAPS de Três Passos e refletir se as atividades ofertadas aos pacientes estavam compatíveis com as necessidades levantadas. Trata-se de um estudo transversal de natureza quantitativa, em que os dados foram coletados através de entrevistas individuais ao longo de 2 meses, cujos instrumentos de coleta de dados foram ficha sociodemográfica, ASSIST, ASI6 Light e Entrevista Diagnóstica do DSM-V. Verificou-se que dos 97 pacientes atendidos no CAPS, 24 eram usuários de substâncias psicoativas. A maioria era homens (79,2%), raça branca (95,8%), natural da própria cidade do estudo (62,5%), não-casados (37,5% solteiros e 25% separados/divorciados) e concentrados na faixa etária dos 41 a 50 anos (33%; Média= 44; Mediana = 41,75; Mínimo = 22; Máximo = 62). Uma minoria estava trabalhando (16,7%) e a metade recebia Auxílio Doença. A principal substância de abuso foi o álcool (66,66%), seguido por cocaína (29,2%). Houve relato de uso de drogas injetáveis (n = 2), mas não nos últimos 3 meses. Com base nos escores médios gerados pela ASI6 Light, as áreas de maior gravidade foram de problemas psiquiátricos (0,11; DP = 0,48), problemas médicos (0,04; DP = 0,48) e problemas relacionados ao álcool (-0,66; DP = 0,48). As áreas que menos pontuaram foram as de problemas com drogas (-1,81; DP = 1,68), problemas sociofamiliares ( -2,34; DP = 1,31) e problemas legais (-2,55, DP = 1,91). Na área de emprego/sustento um pouco mais da metade dos usuários (n=13, 54,17%) considera que não possuem renda suficiente para pagar as necessidades básicas. Em relação às atividades ofertadas no CAPS, a área da Psicologia concentra o maior número de consulta no período (40 consultas), o que vem de encontro as necessidades dos usuários que apresentaram escores altos na área de problemas psiquiátricos. Entretanto, os escores elevados de problemas médicos demonstraram a necessidade da ampliação da atuação de profissionais da área médica (25 consultas) e de enfermagem (6 consultas). Da mesma forma, o elevado número de Benefício/Auxílio Doença e a opinião dos sujeitos de pesquisa de que sua renda é insuficiente para o sustento indicam mais atenção ao aspecto social no planejamento do plano terapêutico. Em suma, a padronização de um instrumento que avalia múltiplas esferas da vida do paciente, como ASI6 Light, favorece uma avaliação mais complexa dos pacientes e o levantamento mais detalhado das suas necessidades, podendo contribuir para planos de tratamento mais concordantes com a situação atual dos pacientes. / This research´s objective was to know the profile of the people who use psychoactive substances at CAPS in Três Passos, RS and analize if the activities offered to the patients were in accordance to the necessities raised. It was a cross-sectional study with a quantitative nature, in which the data were collected through individual interviews during 2 months, whose instruments of data collection were socio-demographic record, ASSIST, ASI6 Light and DSM-V Diagnostic Interview. It was verified that of the 97 patients attended at CAPS, 24 were users of psychoactive substances. The majority were men (79.2%), caucasian (95.8%), born in Três Passos (62.5%), unmarried, (37.5% single and 25% separated /divorced) and concentrated in the age group of 41 to 50 years old (33%, median = 44, mean = 41,75 minimum = 22, maximum = 62). A few people were working (16.7%) and half received Sickness Aid. The main substance of abuse was alcohol (66.66%), followed by cocaine (29.2%). There were reports of injecting drugs use (n = 2), but not in the last 3 months. Based on the scores generated by ASI6 Light, the most serious areas were of psychiatric problems (0.11, SD = 0.48), medical problems (0.04, SD = 0.48) and problems related to alcohol ( -0.66, DP = 0.48). The areas that scored the least were those with drug problems (-1.81, SD = 1.68), socio-family problems (-2.34, SD = 1.31) and legal problems (-2.55, SD = 1.91). In the area of employment / support a little more than half of the users (n = 13, 54.17%) consider that they don´t have enough income to pay for the basic necessities. In relation to the activities offered at CAPS, the Psychology area concentrates the highest number of appointments in the period (40 visits), which meets the needs of users who presented high scores in the area of psychiatric problems. However, the high scores of medical problems showed the need of expanding the performance of medical professionals (25 appointments) and nursing (6 appointments). Likewise, the high number of Benefit / Sickness Aid and the opinion of the interviwed people that their income is not enough, indicate more attention needed to the social aspect in the planning of the therapeutic plan. In short, the standardization of an instrument that evaluates multiple spheres of the patient's life, such as ASI6 Light, enables a more complex evaluation of the patients and a more detailed survey of their needs, being able to contribute to better treatment plans according to the current situation of the patients.

A organização da rede a partir de um centro de atenção psicossocial para o cuidado ao usuário de drogas

Siniak, Débora Schlotefeldt January 2018 (has links)
Trata-se de um estudo quantitativo, descritivo, tipo estudo de caso. O objetivo foi analisar a organização da rede para o atendimento de usuários de drogas a partir de um Centro de Atenção Psicossocial – Álcool e Drogas. A pesquisa foi realizada em um município da Fronteira Oeste do Rio Grande do Sul, Brasil. A coleta de dados ocorreu no período de Agosto à Dezembro de 2017 e dividiu-se em dois estágios seguindo as orientações de Blanchet e James (2011). A análise dos dados foi organizada a partir da utilização de um programa chamado Ucinet que realiza a mensuração dos dados obtidos e permite uma análise visual através da representação gráfica da rede. O estudo norteia-se pelo referencial metodológico de Análise de Redes Sociais (ARS). Os resultados apontaram a existência de 37 atores envolvidos de forma direta ou indireta no cuidado aos usuários de drogas dentro do município. Verificou-se que grande parte das métricas apresentou valores mais elevados com relação ao encaminhamento e recebimento de usuários dentro do sistema, caracterizando a maior parte dos vínculos realizados entre os atores. Por outro lado, as métricas que se referem à coordenação de casos, programas conjuntos e consultorias, que representam o grau de interação entre os dispositivos, tiveram métricas bastante inferiores. Estes resultados demonstram a dificuldade por parte da rede em atuar de forma integrada e construir possibilidades de cuidado conjuntas. O Centro de Atenção Psicossocial – Álcool e Drogas e a Estratégia Saúde da Família são alguns dos principais serviços que encaminham e também recebem demandas relacionadas aos usuários de drogas. Frente a isso, defende-se a ideia de que o trabalho em rede deve ser pautado na horizontalidade, reservando-se o papel específico de cada um deles e da importância estratégica na condução ou participação nas ações de cuidado em saúde mental. Portanto, precisamos vislumbrar a rede com a ideia de descentralização e conectividade entre os atores. Neste escopo, é preciso pensar em formas de atuação conjunta que propiciem a construção de um sistema verdadeiramente integrado e de cooperação. / It is a quantitative study, descriptive case study. The objective was to analyze the organization of the network for the care of drug users from a Psychosocial Care Center - alcohol and drugs. The survey was in a municipality in the western border of Rio Grande do Sul, Brazil. Data collection took two stages following the guidelines of blanchet and James (2011) and occurred in the period from August to December 2017. The data analysis was organized from the use of a program called ucinet that performs the measurement of the data obtained and allows a visual analysis through the graphical representation of the network. The study was guided by the methodological framework of social network analysis (SNA). The results indicated the existence of 37 actors involved directly or indirectly in the care of drug users within the municipality. It was found that great part of the metrics presented higher values with respect to the forwarding and receipt of users within the system, characterizing the majority of bonds made between the actors. On the other hand, the metrics that relate to the coordination of cases, joint programs and consultancies, which represent the degree of interaction between devices, had much lower metrics. These results demonstrate the difficulty on the part of the network to act in an integrated manner and build opportunities for joint care. The Psychosocial Care Center - Drug and Alcohol and the Family Health Strategy are some of the main services that route and also receive demands related to drug users. Face it, defends the idea that within the network there should be no hierarchy or degree of importance among the services, because each of them has its role and has different characteristics, which are fundamental to the establishment and maintenance of networking. Therefore, we need to discern the network with the idea of decentralization and connectivity between the actors. In this scope, it is necessary to think in forms of joint action that is conducive to the construction of a truly integrated system and cooperation.

Análise numérica e experimental de blocos de concreto armado sobre duas estacas com cálice externo, parcialmente embutido e embutido utilizado na ligação pilar-fundação / Numerical and experimental analysis of two pile caps reinforced concrete with external, partially embedded and embedded socket used in column-foundation connection

Barros, Rodrigo 08 November 2013 (has links)
Esta pesquisa estuda o comportamento de blocos de concreto armado sobre duas estacas utilizado na ligação pilar-fundação de estruturas de concreto pré-moldado, submetida a ação de força centrada. Nessa situação, a ligação pilar-fundação pode ocorrer por meio do cálice de fundação, que por sua vez pode estar embutido, parcialmente embutido com parte do colarinho saliente, ou externo com o colarinho saliente em relação ao bloco de fundação. Apresenta-se nesta pesquisa o estudo experimental e numérico de blocos de fundação sobre duas estacas com cálice externo, parcialmente embutido e embutido, submetidos à ação centrada utilizando modelos em escala reduzida 1:2. Nos modelos analisados, considerou-se a conformação das paredes do cálice e do pilar com e sem rugosidade. Os resultados são comparados a dois blocos de referência, os quais apresentaram ligação monolítica entre o pilar e o bloco. Foi desenvolvida análise numérica tridimensional utilizando programa baseado no método dos elementos finitos (MEF), na qual foi considerada a não-linearidade física dos materiais. Observa-se que os blocos da série com rugosidade apresentaram maior rigidez e maior força última comparados aos blocos da série sem rugosidade. A armadura adicional utilizada nos modelos sem interface rugosa conferiu aumento na resistência dos modelos na ordem de 15%, o que não ocorreu nos modelos com rugosidade. Particularmente, no caso de blocos com cálice embutido e sem rugosidade, observou-se comportamento de bloco flexível, diferente dos demais modelos. / The present research studies the behavior of two pile caps reinforced concrete used in column-foundation connection of precast concrete structures, submitted to centered load. This situation allows that pile-foundation connection can occur by socket, which can be embedded, partially embedded or external, with socket walls over the pile caps. The research presents an experimental and numerical study of two pile caps reinforced concrete with external, partially embedded and embedded socket, submitted to centered load, using 1:2 scaled models. These models present the socket walls with rough and smooth interface. The results are compared with two reference models, which present a monolithic connection between pile caps and column. Three-dimensional numerical analyses using software based on finite element method (FEM) were developed considering the nonlinear physical behavior of the material. It was observed that pile caps with rough interface present stiffness and ultimate load greater than pile caps with smooth interface. Additional reinforcement using on models with smooth interface add a 15% resistance on models, but this effect did was not observed on the model with rough interface. Particularly, models with smooth interface and embedded socket present a flexible pile caps behavior.
