Este é um trabalho teórico-empírico que visa principalmente verificar o estado da literatura científica no que diz respeito à consideração dos custos de financiamento da necessidade de capital de giro (NCG) aplicado em mercadorias (NCGp), especialmente em relação aos aprimoramentos do modelo do lote econômico de compras/produção (LEC/LEP). A revisão de literatura mostra diversos modelos aprimorados do LEC/LEP que usam as técnicas de valor presente líquido e fluxos de caixa descontados para considerar o custo do capital no tempo, mas, segundo diversos autores, a diferença entre o LEC original e o uso de tais técnicas é desprezível. Além do mais, o uso destas técnicas não significa que tais modelos tenham incorporado o custo do financiamento da NCGp. Alguns trabalhos, mais recentes, já trazem simulações que levam em consideração o NCGp, outros até já exibem a fórmula NCGp = Estoquesp+Clientesp+Fornecedoresp. Neste trabalho foram feitas 128.000 simulações estocásticas de um modelo dinâmico, de onde se extraíram as variáveis da DRE de cada membro de uma cadeia de suprimentos (CS) hipotética. Foi testada a hipótese de ser este modelo aprimorado, porque incorpora o custo do capital de giro empregado nas mercadorias, mais correto que o modelo que não o incorpora. Para fazer este teste, foi feita uma modelagem (em Excel R) de uma CS contendo dois fornecedores industriais, uma fábrica, um atacadista e um varejista. O modelo recebe como inputs as demandas agregadas do varejista nos dias de cada simulação, que são 360 dias. Os dados foram importados no software estatístico R e as variáveis de saída foram então analisadas nos diversos cenários, regimes e tipos de demanda. Os resultados da análise dos diferentes cenários mostram que é importante considerar os custos financeiros da NCGp. / This is a theoretical and empirical work that primarily aims to check the status of scientific literature with regard to the consideration of the costs of financing the working capital needs (WCN ) applied to goods (WCNp), especially in relation to improvements of economic order/- production quantity (EOQ/EPQ) models. The literature review shows several EOQ/EPQ enhanced models that use net present value and discounted cash flows techniques to consider the cost of capital over time; but according to several authors, the difference between the original EOQ model and with the use of such techniques is negligible. Moreover, the use of these techniques does not mean that such models have incorporated the cost of financing the WCNp. Some latest papers make simulations that consider the WCNp, others have even used the formula WCNp = Inventoriesp +Receivablesp +Payablesp. In this study we made 128,000 stochastic simulations of a dynamic model, from where the were obtained the result\'s variables for each member of a hypothetical supply chain(SC).We tested the hypothesis that this enhanced model, because it incorporates the cost of working capital employed in goods, is more correct than the model that does not. For this test, we made a model (in Excel R) of a CS containing two industrial suppliers, a factory, a wholesaler and a retailer. The model takes as inputs the aggregated demands of the retailer in the days of each simulation, which is 360 days. Data were imported into R statistical software and the output variables were then analyzed in different scenarios, regimes and types of demand. The results of the analysis of different scenarios showed that it is important to consider the financial costs of WCNp, maybe incorporating them into an enhanced EOQ/EPQ model.

The purpose of this qualitative case study is to explore the literacy practices of marginalized adolescent youth in India and the relationship of these practices to imagination and identity construction. More than just tools for communication, language and literacy practices allow individuals to express their selves and identities as they voice their thoughts, negotiate meaning (Dyson & Genishi, 2005; Gee, 2003), and enact themselves within society (Janks, 2010; New London Group, 1996). This qualitative case study took place in Lucknow, India; the subjects were a group of adolescent girls at a nonprofit all-girls school in a seventh-grade classroom. Using discourse analysis, the data revealed the ways in which the girls used literacy to agentively position themselves as actual selves in their societies, as imagined social selves and others, in relationship to social others, and in imagined events.

In order to achieve this objective, Design Science was used as a research method, in which a static simulation model is proposed and several scenarios are analyzed and evaluated in relation to important Production Management theories. The model proposed to represent a flow shop uses the Factory Physics equations (HOPP; SPEARMAN, 2008) e considers the following shop-floor variables: i) the average setup time; ii) average defect rate; iii) mean time between failures; iv) mean time to repair the machine; v) variability in processing time; vi) variability of the time between arrivals of orders and vii) transfer batch size. The results demonstrate that for both balanced and unbalanced environment, transfer batch size has little effect on lead time, when operating with a process batch size away from optimal batch size (minimum point of the lead time - lot size curve proposed by Karmarkar et al. (1985)). To get a good lead time performance, it is first necessary to reduce process batch size before making efforts to reduce transfer batch. For an unbalanced environment, reducing process batch size only at the bottleneck, coupled to transfer batch size reduction across the flow shop, provided a lead time reduction on the order of 30%, while the remainder flow shop operated with large process batches. In such configuration, the contribution from setup time reduction at the bottleneck machine has generated a small effect on the lead time performance considering the parameters used in this work. / Esta tese se propõe a avaliar o efeito do tamanho do lote de transferência na redução do lead time em ambientes flow shop (balanceado e não balanceado, com a presença de um recurso gargalo). Para atingir tal objetivo, foi utilizado como método de pesquisa o Design Science, no qual um modelo de simulação estático é proposto e diversos cenários são analisados e avaliados em relação a grandes teorias da Gestão da Produção. O modelo aqui proposto para representar um flow shop utiliza as equações do Factory Physics (HOPP; SPEARMAN, 2008) e considera as seguintes variáveis de chão-de-fábrica: i) tempo médio de setup; ii) taxa média de defeitos; iii) tempo médio entre falhas; iv) tempo médio de reparo da máquina; v) variabilidade do tempo de processamento; vi) variabilidade do tempo entre as chegadas de ordens e vii) tamanho do lote de transferência. Os resultados demonstram que tanto para um ambiente balanceado quanto para um ambiente desbalanceado, o tamanho do lote de transferência tem pouco efeito no lead time, quando se opera com um tamanho de lote de produção longe do tamanho de lote ótimo (ponto mínimo da curva lead time – tamanho de lote de produção, proposta por Karmarkar et al. (1985)). Para se obter um bom desempenho em relação ao lead time, é preciso primeiramente reduzir o tamanho do lote de produção, antes de se empreender esforços para a redução do lote de transferência. Em relação a um ambiente desbalanceado, a redução do tamanho do lote de produção apenas no recurso gargalo, aliada à redução do tamanho do lote de transferência em toda a linha, proporcionou uma redução no lead time da ordem de 30%, quando o restante da linha operava com grandes lotes de produção. Nessa configuração, a contribuição da redução do tempo de setup da máquina gargalo gerou um efeito pequeno na redução do lead time, para os parâmetros utilizados nesse trabalho.

En la presente tesis se tiene como objetivo determinar cómo solucionar el problema de desabastecimiento de materiales críticos de la empresa Consorcio Cam Lima. Para ello, se tuvo que realizar una descripción general de la empresa, enfocándonos en los procesos logísticos ya existentes donde se pudo identificar las necesidades diarias de las líneas operativas de la empresa, los materiales que se encuentran en dichas necesidades y la frecuencia y cantidad que requieren los usuarios para poder realizar sus actividades eficientemente y en el periodo establecido. Se pudo analizar los procesos y procedimientos que los usuarios y las áreas de apoyo toman en cuenta para que se pueda realizar el abastecimiento de materiales críticos, además de los necesarios para una correcta reposición de materiales por parte del área logística, que involucra el área de almacén y compras, y mantener una completa exactitud de inventarios físicos y del sistema. Con dicho análisis, se pudo comprobar que los usuarios no se planifican y generan los requerimientos de materiales a última generando una incorrecta reposición del inventario, además se pudo comprobar que los errores y demoras en la digitación de entradas y salidas de materiales en el sistema no era una causa de la inexactitud de inventarios, obteniendo hallazgos como omisión de algunas actividades en el proceso de recepción de materiales físicos. En el planteamiento de la mejora se determinó que materiales críticos se comportan como una demanda estacional, por lo que para poder obtener el pronóstico de la demanda se utilizó el modelo de suavización exponencial. Finalmente, se propone implementar un plan de abastecimiento a partir del análisis del modelo de lote económico y un kardex físico por cada material registrando cada ingreso y salida del almacén. In the present investigation is intended to determine how to solve the problem of shortage of materials critical of the company Consortium Cam Lima. For this, had to carry out a general description of the company, focusing on existing logistics processes which were unable to identify the daily needs of the operation guidelines of the company, what are those needs and frequency and amount that require users to be able to carry out its activities efficiently and in the set period of time. I could analyze the processes and procedures that users and support areas taken into account so that the supply of critical materials, in addition to those necessary for a correct replacement of materials by the logistics area, can be that it involves the warehouse and shopping area, and maintain a complete physical inventory and system accuracy. With this analysis, it was proven that users not planned is and generate the requirements of latest materials generating an incorrect replacement of the inventory, also failed to check the errors and delays in the fingering of inputs and outputs of material in the system was not a cause of the inaccuracy of inventories, obtaining findings as omission of certain activities in the process of receiving physical materials. On the approach of improving was determined that critical materials behave as a seasonal demand, so for demand forecasting model of exponential smoothing was used. Finally, intends to implement a plan of supply from the analysis of the model of the economic lot and a physical kardex by each material registering every entrance and exit the warehouse.

El proyecto de rediseño del sistema se ha realizado para mantener la operación activa y el flujo de medicamentos en la empresa. Si bien la farmacia o el almacén principal representa el 10% de los ingresos netos de la organización, es la principal área de apoyo para los principales servicios ofrecidos por la clínica a los clientes, ya que es responsable del suministro médico al consumidor interno y externo donde se interactúa con las actividades de la empresa. La implementación del proyecto consistió en calcular los lotes óptimos para cada línea de productos que se agruparon para un mejor tratamiento de los medicamentos: 700 artículos a 50 familias. Las líneas de productos para aquellos con características similares se definieron y se pudieron comprar a un proveedor en particular. Además, se establecieron descuentos para reducir los niveles de precios en la farmacia. En relación con el control de stock, se estableció el Plan Cíclico basado en el análisis Multicriterio ABC. Como parte del alcance del proyecto, se tomó una muestra con un nivel de confianza del 90% de la implementación del tipo de producto "A" total para aplicar durante 3 meses. En efecto, los pedidos de productos elegidos en el Plan Piloto cayeron del 80% al 12.5% de las ventas no atendidas por la falta de disponibilidad de existencias y los altos precios. Los resultados se lograron con la implementación de nuevos procedimientos de POES que involucran a los responsables de las áreas de la Clínica. / The System redesign project has been done in order to maintain active operation and flow of medicines in the company. Although Pharmacy - or main warehouse - accounts for 10% of net income in the organization, it is the main area of support for the main services offered by the clinic to the customers, because it is responsible for the medical supply to consumer internal and external interacting with the activities of the company. The implementation of the project was to calculate the optimal batch order for each product line, which were grouped for better treatment of medicines - 700 items to 50 families. Product lines for those with similar characteristics were defined and could be purchased from a particular vendor. Also, discounts were established to reduce the levels of prices in the pharmacy. In relation to stock control, counting Cyclical Plan based on analysis Multicriteria ABC was established. As part of the project scope, a sample at 90% confidence level of total product type “A” implementation to apply for 3 months was taken. In effect, orders for products chosen in the Pilot Plan fell from 80% to 12.5% of sales not served by non-availability of stock and high prices. The results were achieved with the implementation of new POES procedures involving those responsible for the areas in the Clinic. / Tesis

<p dir="ltr"><a href="" target="_blank">ABSTRACT</a></p><p dir="ltr">This dissertation delves into postmodern wordless picture books, employing a multimodal content analysis across twenty-eight titles. It stands on a theoretical framework amalgamating concepts from multimodality grounded in social semiotics, critical literacy, and postmodernism. Among the corpus, three titles— <i>Alien Nation</i> (Bassi, 2021), and <i>The Rabbits</i> (Tan, 1998) and <i>The Other Side</i><i> </i>(Bányai, 2005)— emerge as principal subjects of analysis, with the remaining twenty-five titles providing contextual support. Guiding this journey is Barthes' (1977) tripartite model of visual textual meaning at the literal, symbolic, and personal levels, illuminating the intricate layers of the analyzed picture books.</p><p dir="ltr">The analysis unveils distinguishing features of these books: 1) Disruption of boundaries of story worlds and reality; 2) Disruption of space and/or time; 3) Multiple levels of intertextuality; 4) Visual incongruity, visual metaphor and 5) Personal Narratives. Such characteristics are found to challenge narrative conventions, blur reality-fiction distinctions, and implore readers to cultivate personal narratives and critical interpretations.</p><p dir="ltr">However, the research's significance extends beyond feature identification. It births a postmodern literacy pedagogy that encompasses visual, critical, and postmodern dimensions. This pedagogy advocates for embedding postmodern wordless picture books in pre-service teacher curricula. The aim surpasses genre acquaintance, aspiring for a profound grasp of the books' visual nuances and ideological layers. As these visual dynamics play a pivotal role in shaping a reader's experience, they bolster critical reading and foster personal and emotive connections to narratives. By engaging with such books, pre-service teachers gain multifaceted insights into intricate social and historical issues. They're empowered to question prevailing narratives, embrace diverse perspectives, and champion social justice and educational equity. Viewed through this prism, postmodern wordless picture books serve as powerful tools, guiding future educators to see the world from diverse perspectives, navigate uncertainties, foster empathy, and empower varied voices, ultimately becoming advocates for change and inclusion.</p>

<p>In order to comfortably and effectively function in U.S. classrooms, both international students and domestic students benefit from the development of interactive and intercultural communication skills. At Purdue University, a large, public, R1 institution with a substantial international population, the internationalization of the student body is a priority. To examine the relationship between academic and social integration of international and domestic students on campus, international (ESL) undergraduate students (L2 English, n=253) from the Purdue Language and Cultural Exchange Program (PLaCE), and domestic undergraduate students (L1 English n=50) from the first-year composition program (ICaP), participated in a voluntary survey. The framework for investigating students’ interaction with peers and teachers was derived from Severiens and Wolff (2008). Four aspects of new, incoming students’ adaptation (Global Perspective, Intercultural Competence, Acculturation Mode, and Willingness to Communicate) were addressed by the survey. Although there were similarities between international and domestic students, the results revealed international students had more opportunities to interact with peers from diverse language backgrounds in formal academic contexts, including classroom activities, peer-group work in first-year programs and language programs. However, in informal, social contexts, neither international nor domestic students took advantage of opportunities to interact with each other. The tendency to prefer social interactions with co-nationals may contribute to social isolation and limited integration of international and domestic students within broader social contexts outside of classrooms. Yet, rather than resisting this trend, instructors and administrators might enhance opportunities for interaction in academic contexts where both groups are most willing to participate. Findings from this study can contribute to the development of first-year programs that provide realistic solutions for the enhanced internationalization of both domestic and international students on campus. </p>

A utilização de enzimas como aditivos alimentares para poedeiras comerciais pode aumentar a digestibilidade dos nutrientes dos ingredientes da dieta. Assim, o objetivo do trabalho foi avaliar os efeitos da suplementação de enzima xilanase em dietas de poedeiras comerciais à base de milho e soja sobre desempenho, morfologia intestinal e incremento de energia da dieta. Foram utilizadas 400 poedeiras da linhagem Hy-line, variedade W36 com duas semanas de idade submetidas às dietas experimentais até as 80 semanas de idade. As aves foram distribuídas em delineamento inteiramente casualisado em esquema fatorial 2x2 (nível de energia x inclusão de xilanase), totalizando 4 tratamentos com 10 repetições de 10 aves cada. Os tratamentos foram: controle positivo (dieta balanceada para respectiva idade); controle positivo+xilanase; controle negativo (dieta com redução de 100 kcal/kg no nível de EM); controle negativo+xilanase. Nas fases de cria e recria (2 a 6 e 7 a 17 semanas), foram realizadas as avaliações para peso corporal, ganho de peso, consumo de ração, conversão alimentar, viabilidade criatória e uniformidade do lote. As seis e 16 semanas foram colhidos fragmentos de intestino das porções duodeno, jejuno e íleo para mensurações de altura de vilo e profundidade de cripta. Durante a fase de postura (18 a 80 semanas) foram avaliadas características de desempenho (ganho de peso, consumo de ração, produção, peso e massa de ovos, conversão alimentar e viabilidade criatória). Foram realizados ainda, quatro ensaios de digestibilidade (14, 36, 60 e 80 semanas) para determinação da energia metabolizável aparente e energia metabolizável aparente corrigida das dietas e coeficientes de metabolizabilidade dos nutrientes. Conclui-se que a suplementação de xilanase em dietas de poedeiras com redução de 100 kcal/kg de energia metabolizável promove melhor formação da mucosa intestinal e o fornecimento de dietas com níveis de energia adequados associadas à suplementação de xilanase proporciona valores de energia metabolizável (EMA) e energia metabolizável corrigida (EMAn) superiores em relação aos valores obtidos com dietas sem suplementação de enzima para fase de postura. Além disso, a adição de xilanase em dietas de poedeiras comerciais, a base de milho e soja possibilita a redução do nível de energia da dieta sem prejudicar o desempenho das aves. / The use of enzymes as feed additives for laying hens can increase the digestibility of nutrients present in diet. Thus, the objective was to evaluate the effects of xylanase enzyme supplementation in diets of laying hens based corn and soybean on performance, gut morphology and increased energy diet. Were used 400 layers of Hy-line W36 with two weeks of age fed experimental diets until 80 weeks of age. The birds were distributed to a completely randomized design in a 2x2 factorial (including energy level x xylanase), totaling four treatments with 10 replicates of 10 birds each. The treatments were: positive control (balanced diet to the age), positive control + xylanase, negative control (diet with a reduction of 100 kcal/kg ME) and negative control + xylanase. In phase of rearing (2 to 6 and 7 to 17 weeks), evaluations were made for body weight, weight gain, feed intake, feed conversion, livability and uniformity. At six and 16 weeks were collected fragments intestine of portions duodenum, jejunum and ileum for measurement of villus height and crypt depth. During the laying phase (18 to 80 weeks) were evaluated performance characteristics (weight gain, feed intake, production, weight and egg mass, feed conversion and livability). Were also conducted four assays of digestibility (14, 36, 60 and 80 weeks) to determine the apparent metabolizable energy and apparent metabolizable energy corrected, coefficients of metabolization of diet nutrients. It was concluded that supplementation xylanase in diets of laying hens with reduction of 100 kcal/kg of metabolizable energy promotes better formation of the intestinal mucosa and compensates for the reduction of dietary energy, providing metabolizable energy and feeding diets with energy levels associated with adequate supplementation of xylanase provide values metabolizable energy and corrected metabolizable energy above to the values obtained with diets without supplementation enzyme to the production phase. Furthermore, the addition of xylanase in diets for laying hens, based corn and soybeans, allows reduction in the level of dietary energy without damaging the performance of birds.
