Os programas de transferência condicionada de renda (TCR) entram na agenda pública por sua potencialidade em interferir no ciclo intergeracional de pobreza. Este artigo tem como objetivo analisar o processo de formulação das condicionalidades de saúde do Programa Bolsa Família e, secundariamente, avaliar sua interface com a trajetória das políticas de alimentação e nutrição no Brasil. Para isso, o estudo adotou como referencial analítico o modelo de análise de múltiplos fluxos, proposto por Kingdon, para quem a mudança na agenda pública acontece com a convergência entre o fluxo dos problemas, o fluxo das soluções e alternativas e o fluxo político. A trajetória desses fluxos foi recomposta por meio da análise de documentos governamentais e de relatos orais obtidos por meio de entrevistas. No momento da formulação das condicionalidades de saúde, no fluxo de problemas, havia a necessidade de mudar a estratégia de combate à desnutrição, devido às críticas ao Incentivo ao Combate às Carências Nutricionais (ICCN) e à extinção do Programa de Distribuição de Estoques de Alimentos (PRODEA). No que diz respeito ao fluxo das soluções, diversas propostas de TCR estavam em curso. No fluxo político, havia a decisão de criação de uma rede de proteção social. Nesse processo, a Coordenação Geral da Política de Alimentação e Nutrição assumiu o papel de empreendedora de políticas. A reflexão sobre esse processo ajuda a compreender o papel dos serviços de saúde em um programa de caráter intersetorial.

The aim of my project is to find operational strategies for increasing the commercial exploitation of fish in Apulia region and to acquire a thorough knowledge of several important aspects of this system order to propose concrete, suitable and appropriate development tools. The plan is to analyze the impact that the socio-economic context has on blue fish systems of fishing and marketing in the various maritime regions. The sector of fishery is typified by a settled downward trend due to both communitarian policies driving towards a reduction of the fishery effort and to reduction of fishing resources. In the same time in Italy a increasing of costs (expecially fuel) and a reduction of market prices, because of the increasing of imports, are observed. Although a big part of Italian fishing fleet is to be referred to Apulia region, this dynamics are worsen, here, also because of market inefficiency and lack of integration and cooperation among fishermen. In this first part of my work I have investigated two areas that are relevant for regional fishery. On a first step I have evaluated fish amount for each kind of dealer working in each one of the two areas than, according to Porter's value chain analysis theory. Than i have applied the approach of value system to evaluate the value chains of the firm's supplier, the firm of fishery itself, and the firms distribution channels. Distribution of value has been resulted different but very unfavorable to fisherman in both investigated areas. The second step of my study has been the evaluation of the social capital value in both areas, defining the networks of fishery consistence and number of their mutual relationship. Results lay stress on a relation to an higher social capital value and a distribution of value system more profitable for fishermen.

The purpose of the PhD research was the identification of new strategies of farming and processing, with the aim to improve the nutritional and technological characteristics of poultry meat. Part of the PhD research was focused on evaluation of alternative farming systems, with the aim to increase animal welfare and to improve the meat quality and sensorial characteristics in broiler chickens. It was also assessed the use of innovative ingredients for marination of poultry meat (sodium bicarbonate and natural antioxidants) The research was developed by studying the following aspects: - Meat quality characteristics, oxidative stability and sensorial traits of chicken meat obtained from two different farming systems: free range vs conventional; - Meat quality traits of frozen chicken breast pre-salted using increasing concentrations of sodium chloride; - Use of sodium bicarbonate in comparison with sodium trypolyphosphate for marination of broiler breast meat and phase; - Marination with thyme and orange essential oils mixture to improve chicken meat quality traits, susceptibility to lipid oxidation and sensory traits. The following meat quality traits analyseswere performed: Colour, pH, water holding capacity by conventional (gravimetric methods, pressure application, centrifugation and cooking) and innovative methods (low-field NMR and DSC analysis) ability to absorb marinade soloutions, texture (shear force using different probes and texture profile analysis), proximate analysis (moisture, proteins, lipids, ash content, collagen, fatty acid), susceptibility to lipid oxidation (determinations of reactive substances with thiobarbituric acid and peroxide value), sensorial analysis (triangle test and consumer test).

Human development causes degradation of stream ecosystems due to impacts on channel morphology, hydrology, and water quality. Urbanization, the second leading cause of stream impairment, increases the amount of impervious surface cover, thus reducing infiltration and increasing surface runoff of precipitation, which ultimately affects stream hydrologic process and aquatic biodiversity. The main objective of this study was to assess the overall health of Miller Run, a small tributary of the Bull Run and Susquehanna River watersheds, through an integrative hydrologic and water quality approach in order to determine the degree of Bucknell University’s impact on the stream. Hydrologic conditions, including stage and discharge, and water quality conditions, including total suspended solids, ion, nutrient, and dissolved metal concentrations, specific conductivity, pH, and temperature, were measured and evaluated at two sampling sites (upstream and downstream of Bucknell’s main campus) during various rain events from September 2007 to March 2008. The primary focus of the stream analysis was based on one main rain event on 26 February 2008. The results provided evidence that Miller Run is impacted by Bucknell’s campus. From a hydrologic perspective, the stream’s hydrograph showed the exact opposite pattern of what would be expected from a ‘normal’ stream. Miller run had a flashier downstream hydrograph and a broader upstream hydrograph, which was more than likely due to the increased amount of impervious surface cover throughout the downstream half of the watershed. From a water quality perspective, sediment loads increased at a faster rate and were significantly higher downstream compared to upstream. These elevated sediment concentrations were probably the combined result of sediment runoff from upstream and downstream construction sites that were being developed over the course of the study. Sodium, chloride, and potassium concentrations, in addition to specific conductivity, also significantly increased downstream of Bucknell’s campus due to the runoff of road salts. Calcium and magnesium concentrations did not appear to be impacted by urbanization, although they did demonstrate a significant dilution effect downstream. The downstream site was not directly affected by elevated nitrate concentrations; however, soluble reactive phosphorus concentrations tended to increase downstream and ammonium concentrations significantly peaked partway through the rain event downstream. These patterns suggest that Miller Run may be impacted by nutrient runoff from the golf course, athletic fields, and/or fertilizers applications on the main campus. Dissolved manganese and iron concentrations also appeared to slightly increase downstream, demonstrating the affect of urban runoff from roads and parking lots. pH and temperature both decreased farther downstream, but neither showed a significant impact of urbanization. More studies are necessary to determine how Miller Run responds to changes in season, climate, precipitation intensity, and land-use. This study represents the base-line analysis of Miller Run’s current hydrologic and water quality conditions; based on these initial findings, Bucknell should strongly consider modifications to improve storm water management practices and to reduce the campus’s overall impact on the stream in order to enhance and preserve the integrity of its natural water resources.

Purpose – A growing body of literature points to the importance of public service motivation (PSM) for the performance of public organizations. The purpose of this paper is to assess the method predominantly used for studying this linkage by comparing the findings it yields without and with a correction suggested by Brewer (2006), which removes the common-method bias arising from employee-specific response tendencies. Design/methodology/approach – First, the authors conduct a systematic review of published empirical research on the effects of PSM on performance and show that all studies found have been conducted at the individual level. Performance indicators in all but three studies were obtained by surveying the same employees who were also asked about their PSM. Second, the authors conduct an empirical analysis. Using survey data from 240 organizational units within the Swiss federal government, the paper compares results from an individual-level analysis (comparable to existing research) to two analyses where the data are aggregated to the organizational level, one without and one with the correction for common-method bias suggested by Brewer (2006). Findings – Looking at the Attraction to Policy-Making dimension of PSM, there is an interesting contrast: While this variable is positively correlated with performance in both the individual-level analysis and the aggregated data analysis without the correction for common-method bias, it is not statistically associated with performance in the aggregated data analysis with the correction. Originality/value – The analysis is the first to assess the robustness of the performance-PSM linkage to a correction for common-method bias. The findings place the validity of at least one part of the individual-level linkage between PSM and performance into question.

We propose that the observed short-term stable isotope fluctuations reflect changes in high- and low-latitude intermediate to deep water sources, based on a high-resolution stable isotope record of planktic and benthic foraminifera from the Early Maastrichtian (~71.3 to ~ 69.6 Ma) of Blake Nose (DSDP Site 390A, North Atlantic). Sources of these waters may have been the low-latitude eastern Tethys and high-latitude North Atlantic. Changes in intermediate to deep water sources were probably steered by eccentricity-controlled insolation fluctuations. Lower insolation favored the formation of high-latitude deep waters due to positive feedback mechanisms resulting in high-latitude cooling. This led to a displacement of low-latitude deep waters at Blake Nose. Higher insolation reduced intermediate to deep-water formation in high latitudes, yielding a more northern flow of low-latitude deep waters.

Las empresas en situación económica negativa, recurren en España a los Expedientes de Regulación de Empleo que es la figura legal que permite ajustar sus plantillas y cuya utilización se acrecienta en épocas de crisis. El objetivo de esta investigación se focaliza en la integración de la Teoría de Opciones Reales en los proyectos organizativos de recursos humanos, en particular en el estudio y aplicación de la opción de contracción y de la opción de aplazamiento a los proyectos de desarrollo de los Expedientes de Regulación de Empleo. Las opciones reales son una herramienta de gestión, novedosa y contrastada, que posibilita realizar la valoración de los Expedientes de Regulación de Empleo tomando en consideración las incertidumbres futuras, lo que permite cuantificar mejor el resultado de la decisión y supone un avance sobre la valoración realizada de forma estática. Dos aspectos clave ha sido necesario resolver. En primer lugar determinar la fuente de incertidumbre que ponga en valor las opciones reales para este tipo de proyectos y como consecuencia desarrollar los procedimientos para obtener el valor de la opción. La puesta en valor de la opción de contracción permite, a partir de la consideración de la demanda como factor de incertidumbre, desarrollar un modelo que proporciona el valor óptimo del número de contratos de trabajo a extinguir, de modo que sitúa a la organización en la mejor posición para la toma de decisiones. La resolución del modelo se logra con la ayuda de la herramienta “The Newsvendor Model”, que facilita la obtención el valor óptimo. En la aplicación de la opción de aplazamiento se ha concluido asimismo, que la volatilidad de la demanda es la fuente de incertidumbre que hace viable la opción y a partir de dicha incertidumbre se ha desarrollado un procedimiento basado en el árbol binomial que permite obtener su valor. Una vez desarrollados los dos modelos para las opciones de contracción y aplazamiento, se ha elaborado un modelo conjunto con ambas opciones, integrando los resultados obtenidos en cada caso. Para validar los modelos obtenidos se presenta su aplicación al caso real de una empresa en situación económica negativa que requiere la necesidad de llevar a cabo un Expediente de Regulación de Empleo, lo que ha permitido comprobar la utilidad de dichos desarrollos, al obtener resultados que facilitan la toma de decisiones y que presentan soluciones que pueden ser más equilibradas para los trabajadores de la empresa, aspecto clave a tener en cuenta, dado el coste personal, familiar y social de este tipo de proyectos. La integración de las opciones reales en la gestión de recursos humanos tiene un amplio campo de aplicación, dadas las diferentes inversiones que se pueden llevar a cabo sobre el capital humano. Aunque esta investigación se ha focalizado en la opcionalidad de las inversiones para el ajuste de plantilla, existen otro tipo de inversiones en recursos humanos, como son las dedicadas a formación, motivación, adecuación o incorporación de personal, que también estarán sujetas a opcionalidad si existen incertidumbres a futuro. Con el objetivo de avanzar en el estudio y aplicación de las opciones reales a estas inversiones, se presenta un marco conceptual que identifica las bases de partida en lo referente a los retornos de las inversiones y las incertidumbres futuras. Con los resultados obtenidos en esta investigación se entiende que se ha conseguido el objetivo de aplicar la Teoría de Opciones Reales a los Expedientes de Regulación de Empleo y con ello establecer la posibilidad de mejorar las implicaciones sociales de estos proyectos dentro de la empresa y en la sociedad. ABSTRACT During crisis times, like the one Spain has been going through on the last years, the Collective Dismissal Procedure is an important issue to be considered within companies that are having a negative economic situation. This research focuses on the integration of the Real Options Theory for organizational projects in the management of human resources, and particularly the study and inclusion of the option to contract and the deferral option in Collective Dismissal Procedures. The Real Options Theory, an innovative management tool that has been proven as correct, help to improve the assessment of the Collective Dismissal Procedures using the dynamic demand instead of the static demand, giving a better quantification of the decision that is going to be taken. Two main issues which are hoped to be resolve are examined: the search for a source of uncertainty to make the real options viable for this type of projects, and consequently the development of a procedure to obtain the value of the option. The option to contract allows, from the consideration of the demand as a factor of uncertainty, to develop a model obtaining the optimal value in the reduction of the workforce, therefore allowing the organization to place itself in the best position for the decision making. The resolution of this model is achieved with the help of "The Newsvendor Model" tool, which facilitates obtaining the optimal value. The analysis performed in the deferral option also concluded that the volatility of demand is the source of the uncertainty that makes the option viable and the procedure developed by the binomial tree is the tool that enables the value of the option to be found. Once developed two models for contraction and deferment options, a joint model has been developed including both options by integrating the results obtained in each case. To validate the models, the real case of a company in negative economic situation requiring the need to carry out a procedure for collective redundancies is applied. This has demonstrated the usefulness of this kind of development that can deliver results to improve the decision making and provide more balanced solutions for company employees, key consideration given the impact on personal, family life and social environment of these Collective Dismissal Procedures. The integration of real options in the management of human resources has broad scope, given the different investments that can be performed on the human capital. Although this research has focused on the optionality of investments for downsizing, there are other investments in human resources for training, motivation, arrangement or incorporation of staff that are also subject to optionality if there are future uncertainties. With the aim of advancing the study and application of real options to these investments, a conceptual framework is presented that identifies the basis of research in terms of the investment returns and future uncertainties. With the results obtained on this research it is clearly defined the objectives for which this work was started for, the application of the Real Options Theory to the Collective Dismissal Procedure. And thereby achieve the final goal of improving the social impact of these projects within a company and society.

La Vega de Aranjuez ha sido desde hace siglos conocida por la notoriedad de sus jardines y huertas históricas y también, en épocas más recientes, por ser la despensa de Madrid. A mediados del siglo XX, sin embargo, con las transformaciones que el sector agrario ha experimentado no sólo a nivel local, sino a escala global, empezó un proceso de declive que se ha acentuado en los últimos años. Paralelamente, en el año 2001, la Unesco declara el Paisaje Cultural de Aranjuez, como Patrimonio de la Humanidad con un valor universal excepcional. Parte de lo que sustenta este reconocimiento a nivel internacional radica en las peculiaridades del paisaje que conforma la actividad agraria. El cambio de orientación, eminentemente hortofrutícola hacia cultivos extensivos y superficies en barbecho, y la pérdida de importancia del sector, no han pasado desapercibidos para la administración local y han sido varios los intentos de recuperación y dinamización del sector en los últimos años. La investigación de la que es objeto esta Tesis Doctoral surgió por iniciativa del Ayuntamiento de Aranjuez, que en al año 2010 deseó conocer la situación del sector hortícola en el municipio, para lo cual, encargó un estudio a la UPM-ETSIA. Para conocer la realidad desde una perspectiva integral, se planteó abordar el análisis desde la perspectiva de Cadena de Valor. Las implicaciones de este concepto, su evolución y su papel como instrumento de análisis de la cadena alimentaria, han sido revisadas y presentadas en el epígrafe del Marco Conceptual. Por cadena de valor se entiende el conjunto de procesos desde el consumidor, a través de los proveedores que proporcionan productos, servicios e información que añaden valor hacia los clientes (Lambert & Cooper, 2000; Chen, 2004). Para el análisis de la situación del sector hortícola en Aranjuez, se procedió en varios pasos, los cuales constituyeron la primera fase de la investigación y contemplaron lo siguiente: 1. La identificación de los problemas y de las demandas de los actores de la cadena, realizando cortes transversales en el mercado a distintos niveles para conocer los puntos de vista de los operadores de la cadena (Gunasekaran & Patel ,2004; Rojas, 2009; Schiefer, 2007). Para ello se diseñaron cuestionarios y se dirigieron a representantes de cinco eslabones de la cadena presentes en el caso de estudio: Agricultores (15), Mayoristas (11), Detallistas (55), Consumidores (85) y Restaurantes (36), tanto en Aranjuez como en Madrid (un total de 202). 2. Análisis D.A.F.O de cada uno de los eslabones y de la cadena completa, como herramienta para identificar y sintetizar la problemática y las potencialidades del sector. 3. Análisis global de la Cadena de Valor mediante el Método de Organización Sectorial, según Briz, de Felipe y Briz (2010), el cual permite estudiar aspectos de la estructura, la conducta y el funcionamiento de la cadena. 4. Jornada de análisis por parte de un Panel de Expertos en la sede de la Fundación Foro Agrario, en la cual se presentaron las conclusiones del análisis de la cadena de valor y se plantearon estrategias para la dinamización del sector. Con los resultados del análisis en esta primera fase de la investigación, se obtuvo una panorámica de la cadena de valor. Algunos de los aspectos más destacados son los siguientes: • El eslabón productivo en Aranjuez está muy atomizado y trabaja por lo general de forma independiente. Cultiva hasta veinte productos hortícolas diferentes, entre los cuales los frutales están casi en desaparición y hay poca presencia de producto ecológico. Le preocupan los precios poco estables y bajos y por lo general no trabaja con contratos. •El eslabón mayorista prácticamente carece de presencia en Aranjuez y está representado en su mayoría por operadores de Mercamadrid, los cuales demandan mayores volúmenes y mejor normalización de los productos hortícolas procedentes de Aranjuez. • El eslabón detallista consultado es diverso (con representación de comercios minoristas, supermercados e hipermercados) y también demanda mayores volúmenes de producción y mejoras en la normalización. Un 80% conoce los productos de Aranjuez, especialmente el espárrago y la fresa-fresón citados en un 74% y 63% de los casos respectivamente. • En el eslabón de consumidores, el 79% de los encuestados da importancia a la procedencia de los productos hortícolas y un 82% conoce los productos de la Huerta de Aranjuez, siendo los más consumidos el espárrago y el fresón. Un 42% de los encuestados compra producto ecológico por razones de salud, sabor y buscando la ausencia de químicos. • El eslabón de restaurantes es un gran consumidor de hortalizas, la gran mayoría de los productos incluidos en el análisis se oferta en más del 75% de los casos. Las más presentes son tomate y espárrago. La fresa y el fresón (en un 83% de los casos), y el espárrago (72%) seguido de la alcachofa (44%) son los productos de Aranjuez que más se conocen en el conjunto de los restaurantes entrevistados. El 75% de los restaurantes prefiere el producto fresco frente al procesado o congelado. La mayoría de los restaurantes locales (92%) estaría dispuesto a incluir en su carta una diferenciación para los productos de Aranjuez. Sin embargo, en el resto de restaurantes el porcentaje es mucho menor (21%). Entre las conclusiones del análisis se evidenció que un 52% de las ventas de los agricultores se realizaba sin intermediarios y un 69% de los consumidores se manifestaba interesado en adquirir productos de Aranjuez directamente del campo a su casa. Se identificó de esta manera que el acortamiento de la cadena se está utilizando como una forma de crear valor. Para profundizar en este aspecto, se planteó una segunda fase en la investigación. Además de estudiar diversos aspectos de los canales cortos de comercialización, se planteó estudiar el enfoque multifuncional de la horticultura, como estrategia para poner en valor la Huerta ribereña. Para dar una coherencia con la fase anterior, el planteamiento se realizó también desde la perspectiva de la cadena de valor, orientando la consulta hacia el eslabón consumidor. De esta manera, se realizó una consulta mediante cuestionario a 221 consumidores sobre diferentes aspectos relativos a los Canales Cortos de Comercialización (CCC) y la Horticultura Multifuncional (HM)1, lo cual permitió realizar un análisis cuantitativo de diferentes variables. Para completar la visión integral de la cadena corta, se seleccionaron 6 proyectos significativos que son ejemplos de diversas tipologías de canales cortos de comercialización en Aranjuez y Madrid, como representantes del denominado eslabón de “Promotores de CCC” y se consultó también a la Asociación de Productores de la Huerta de Aranjuez, constituida formalmente en el año 2014, como representante del eslabón Productor. Para la obtención de información, la cual tiene un carácter cualitativo en el caso de estos dos eslabones de la cadena, se realizaron cuestionarios y Estudios de Caso de cada proyecto. Los cuestionarios de esta segunda fase de consulta a los eslabones de la cadena corta contuvieron cuestiones relativas a los canales cortos de comercialización, tanto a nivel general (concepto de canal corto, puntos fuertes y ventajas que aportan, dificultades para su desarrollo, factores clave para su éxito) como para el caso concreto de la Huerta de Aranjuez (perfil del consumidor, factores implicados en la compra de verduras, utilización de diversas modalidades de canal corto, relación con las tecnologías de la información y comunicación (TICs) y la producción ecológica o la importancia del factor confianza). También aspectos relacionados con la Horticultura Multifuncional, como son, la valoración de diferentes actividades o proyectos de carácter agro-turístico, educativo, social o terapéutico, o la percepción del consumidor de las actividades de huerta como fuente de bienestar y como agente satisfactor de diversas necesidades humanas. Para completar la visión sobre estos dos temas, CCC y HM, se realizó una consulta mediante cuestionario a Expertos en el campo de los canales cortos de comercialización, procedentes del ámbito académico, y a Profesionales en activo trabajando en proyectos de horticultura social y terapéutica. La información aportada, aunque tiene carácter cualitativo, complementa el estudio ofreciendo la perspectiva académica en el caso de los canales cortos y amplía la información sobre la horticultura multifuncional, tratando cuestiones relativas al desempeño profesional o a la formación existente en España en el campo de la horticultura social y terapéutica. Los resultados de esta segunda fase de la investigación, entre otras cuestiones, evidenciaron que: • Los canales cortos de comercialización implican mucho más que la simple reducción de intermediarios y comprenden una gran diversidad de tipologías. • Los casos estudiados, están enfocados en su mayoría al producto ecológico y su funcionamiento está muy fundamentado en el uso de TICs y en el factor confianza. • En relación a la compra de verduras en el ámbito de los canales cortos, son aspectos muy valorados por el consumidor la calidad del producto, la rapidez y frescura con la que llega del campo a la mesa y que el Producto sea recogido en su punto óptimo de maduración. • Las actividades en el ámbito de la horticultura multifuncional son valoradas positivamente por los consumidores, siendo las más puntuadas las de huerto educativo, huerto terapéutico, seguidas de visitas guiadas y degustaciones de productos de huerta en restaurantes. • Por lo general existe una valoración muy alta de la huerta como fuente de bienestar y de satisfacción de necesidades humanas básicas, especialmente las de una alimentación saludable y de conexión con la naturaleza. Para terminar esta síntesis de la investigación realizada, se presentan las principales conclusiones a nivel global de la Tesis, que son las siguientes: 1. La metodología de cadena de valor ha resultado adecuada para conocer la complejidad y el funcionamiento del sector hortícola arancetano desde una perspectiva integral. 2. La Huerta de Aranjuez cuenta con importantes fortalezas, sustentadas en la calidad de sus suelos y en la fama que mantienen sus productos, pero también debilidades. Esto supone poco volumen de producción, que dificulta la relación con mayoristas y grandes detallistas. 3. El acortamiento de la cadena, mediante canales cortos de comercialización se ha identificado como una forma de creación de valor en la cadena. Existen oportunidades de abastecimiento a consumidores de Madrid mediante canales cortos, sin embargo, las modalidades que requieren mayor organización o requisitos de producción ecológica todavía no están desarrolladas. 4. La producción ecológica podría ser una estrategia para crear valor pero todavía es un método de cultivo muy minoritario en la cadena productiva arancetana. 5. Las peculiaridades de la Huerta de Aranjuez propician la puesta en práctica del enfoque multifuncional de la horticultura como vía de desarrollo económico. Los resultados apuntan a una posible demanda de servicios que contemplen actividades de horticultura de carácter educativo, terapéutico y agro-turístico, conducidas por profesionales. Existe una percepción positiva sobre el potencial de la huerta como fuente de bienestar y de satisfacción de necesidades humanas básicas. 6. La puesta en marcha de proyectos empresariales en el ámbito de la horticultura social es una apuesta interesante para crear valor en la huerta que ha sido valorada positivamente por los eslabones de la cadena corta consultados. 7. El campo de la Horticultura Multifuncional que contempla aspectos educativos, sociales y terapéuticos conforma una disciplina con posibilidades de desarrollo que en la investigación se perciben como limitadas por la falta de profesionales y su acceso a una formación adecuada en España. El estudio de los Canales Cortos de Comercialización y de la Horticultura Multifuncional como vías de puesta en valor en el caso de la Huerta de Aranjuez ha tenido un carácter exploratorio y en gran parte cualitativo en esta Tesis Doctoral. Ambos conceptos han desvelado cierta complejidad y requieren de un mayor conocimiento en diversos aspectos para su puesta en práctica con éxito. Se abre, por tanto, un campo para futuras investigaciones que profundicen en estos ámbitos. ABSTRACT La Vega de Aranjuez has been known for centuries for the reputation of its orchards and historic gardens and, more recently, as the pantry of Madrid. However, in the mid-twentieth century, with the transformations in agriculture, not only locally, but globally, began a process of decline that has been accentuated in recent years. Meanwhile, in 2001, Unesco declared Aranjuez Cultural Landscape, as a World Heritage Site with outstanding universal value. Part of what underpins this international recognition lies in the peculiarities of the landscape created by farming. The shift, from an eminently horticultural vocation to extensive field crops and fallow surfaces, and the loss of importance of the sector, have not gone unnoticed for local authorities and have been several attempts at recovery and revitalization of the sector in recent years. The beginning of this research came at the initiative of the municipality of Aranjuez, which in 2010 wanted to know the situation of the horticultural sector, for which he commissioned a study by the UPM-ETSIA. To know reality from an integral perspective, it was proposed to approach the analysis from the perspective of value chain. The implications of this concept, its evolution and its role as an instrument of analysis of the food chain, have been reviewed and presented in Chapter 3.2. The value chain concept refers to all the processes from the consumer, through suppliers who provide products, services and information that add value to customers (Lambert & Cooper, 2000; Chen, 2004). For the analysis of the situation of the horticultural sector in Aranjuez, which constituted the first phase of research, it proceeded in several steps: 1. Identifying the problems and demands of the actors in the chain, making transverse cuts in the market at different levels to meet the views of the chain operators (Gunasekaran & Patel , 2004; Rojas, 2009; Schiefer, 2007). Questionnaires were designed for it and went to representatives of the five links in the chain: Farmers (15), Wholesalers (11), Retailers (55), Consumers (85) and Restaurants (36), both in Aranjuez and Madrid (a total of 202). 2. SWOT analysis of each chain actor and of the whole supply chain, as a tool to identify and synthesize the problems and potential of the sector. 3. Analysis of the whole supply chain by Industrial Organization Method according to Briz et al. (2010), which allows to study aspects of the structure, conduct and performance of the chain. 4. Analysis by a Panel of Experts at Foro Agrario Foundation headquarters, where the conclusions of the analysis were presented and strategies for the revitalization of the sector were raised. The results of the analysis in this first phase of the research, presented an overview of the value chain. Some of the highlights are: - The productive sector in Aranjuez is very fragmented and usually works independently. With a wide variety of horticultural products (up to 20), fruit crops almost disappearing and little presence of organic product. Is concerned about the unstable and low prices and usually does not work with contracts. - The wholesale sector with virtually no presence in Aranjuez is represented mostly by Mercamadrid operators, who demand higher volumes and better standardization of horticultural products from Aranjuez. - The retailer sector is diversified (with representation from retailers, supermarkets and hypermarkets) and also demand higher production volumes and improved standardization. 80% know the products of Aranjuez, especially asparagus and strawberry-strawberry cited by 74% and 63% of cases respectively. - Among the consumers, 79% give importance to the origin of horticultural products and 82% know the products from Aranjuez, the most consumed asparagus and strawberries. 42% buy organic products for health, taste and absence of chemicals. - Restaurants are big consumers of vegetables, most of the products included in the analysis is offered in over 75% of cases. The most: tomato and asparagus. Strawberry (83% of cases), and asparagus (72%) followed by the artichoke (44%) are the products of Aranjuez more known in all the surveyed restaurants. 75% of the restaurants prefer fresh product against processed or frozen. Most local restaurants (92%) would be willing to include in their menu a differentiation for products of Aranjuez. However, for those restaurants from Madrid the percentage is much lower (21%). Among the conclusions of the analysis it showed that 52% of sales were realized from farmers without intermediaries and 69% of consumers expressed interest in acquiring products directly from field to table. It has been identified that the shortening of the chain is being used as a way to create value. To deepen this aspect, a second phase investigation arose. Besides studying various aspects of the short supply chains, it was also proposed to study the functional approach of horticulture as a strategy to add value. To provide consistency with the previous phase, the focus was also conducted from the perspective of the value chain, directing the query to consumers. Thus, again it was used the questionnaire as a methodological tool, and 221 consumers were asked about different aspects of the Short Suppy Chains (SSC) and Multifunctional Horticulture (MH)2, which allowed a quantitative analysis of several variables. To complete the comprehensive view of the short chain, 6 significant projects were selected as examples of different types of short supply chains in Aranjuez and Madrid, representing "SSC Promoters" and also the “Asociación de Productores de la Huerta de Aranjuez”, formally constituted in 2014, was asked representing the productive sector. The Study Case and again the questionnaire were elected as methodological tools in a qualitative analysis. The questionnaires of this second phase of research contained short supply chain issues, as a general topic (short supply chain concept, strengths and advantages they bring difficulties for its development, key factors success) and also refered to the case of Aranjuez (consumer profile, factors involved in the purchase of vegetables, use of several types of short supply chains, relation with information and communication technologies (ICTs) and organic production or the importance of trust in short supply chains). It also contemplated aspects of multifunctional horticulture, such as the valuation of different activities (agro-tourism, educational, social or therapeutic horticulture) and consumer perception about horticultural activities as a source of welfare and satisfactor of human needs. To complete the vision of these two issues, SSC and MH, experts in the field of short supply chains and professionals working in the field of social and therapeutic horticulture were asked. The qualitative information provided, complements the study offering a new perspective in the value chain analysis, such as those relating to job performance, the difficulties encountered or training existing in our country in the field of social and therapeutic horticulture. The results of this second phase of research showed that: Short supply chains involve much more than simply reducing intermediaries and cover a wide range of types. The cases studied are mostly focused on ecological product and its operation is heavily based on the use of ICTs and the trust factor. In connection with the purchase of vegetables in the field of short supply chains, product quality, speed and freshness with which comes from the field to the table and products picked at its peak maturation, are aspects highly valued by the consumer. Activities in the field of multifunctional horticulture are positively valued by consumers, the most scored: the educational garden, therapeutic garden, followed by guided tours and tastings of vegetables from Aranjuez in restaurants. Horticultural activities were highly valuated as a source of welfare and satisfaction of human needs, especially those of healthy eating and connection with nature. To complete this summary, the main conclusions of the research are presented as follows: 1. The value chain approach has been adequate to meet the complexity and operation of the horticultural sector in Aranjuez from a holistic perspective. 2. La Huerta de Aranjuez has important strengths, underpinned by the quality of its soils and fame that keep their products, but also weaknesses. This implies low volume of production, which makes difficult the link with wholesalers and large retailers. 3. The shortening of the chain by short supply chains has been identified as a way of creating value in the chain. Opportunities exist to supply consumers from Madrid by short supply chains, however, methods that require greater organization or requirements of organic production are not yet developed. 4. Organic production could be a strategy to create value but is not generally being implemented in the production chain. 5. The peculiarity of the Huerta de Aranjuez favours the implementation of the multifunctional approach as a means of economic development. The results point to a possible demand for multifunctional horticulture that include educational, therapeutic and agro-tourism activities. There is a positive perception of the potential of horticultural activities as a source of welfare and satisfaction of basic human needs. 6. The implementation of business projects in the field of social horticulture are an interesting way to create value that has been highly valued in the short supply chain. 7. The field of Multifunctional Horticulture which includes educational, social and therapeutic aspects, forms a discipline with possibilities of development, which in research are seen as limited by the lack of professionals and access to adequate training in our country. The study of Short Supply Chains and Multifunctional Horticulture as strategies to create value in the case of the Huerta de Aranjuez has an exploratory character and largely qualitative in this research. Both concepts have revealed some complexity and require greater knowledge in various aspects for successful implementation. It opens therefore a field for future research to deepen in these areas.
Resumo:
Shopfloor Management (SM) empowerment methodologies have traditionally focused on two aspects: goal achievement following rigid structures, such as SQDCME, or evolutional aspects of empowerment factors away from strategic goal achievement. Furthermore, SM Methodologies have been organized almost solely around the hierarchical structure of the organization, failing systematically to cope with the challenges that Industry 4.0 is facing. The latter include the growing complexity of value-stream networks, sustainable empowerment of the workforce (Learning Factory), an autonomous and intelligent process management (Smart Factory), the need to cope with the increasing complexity of value-stream networks (VSN) and the leadership paradigm shift to strategic alignment. This paper presents a novel Lean SM Method (LSM) called ?HOSHIN KANRI Tree? (HKT), which is based on standardization of the communication patterns among process owners (POs) by PDCA. The standardization of communication patterns by HKT technology should bring enormous benefits in value stream (VS) performance, speed of standardization and learning rates to the Industry 4.0 generation of organizations. These potential advantages of HKT are being tested at present in worldwide research.
