Core capabilities are under the above mission areas as outlined in the National Preparedness Goal. Planning, Public Information and Warning, and Operational Coordination cut across all five mission areas. Without these three cross-cutting capabilities, the other capabilities might not be achieved or could be weakened. Other core capabilities are aligned under a specific mission area, based on where it had the most relevance. Core capabilities alignment: Prevention capabilities focus on things related to preventing an imminent terrorist attack; by imminent, we mean an attack that is about to happen ; Protection capabilities focus on security— making sure things, systems, and people are protected ; Mitigation capabilities focus on risk, resilience and building a culture of preparedness; Response capabilities focus on meeting a community’s immediate needs when disaster strikes and finally, recovery capabilities focus on getting communities back on their feet.

Contexto: La idea principal es la creación de una empresa para la fabricación y comercialización de productos cosméticos de alta gama. A pesar del contexto de crisis económica en el que estamos envueltos estos últimos años y del que no parece que acabamos de salir, el sector de la cosmética está resistiendo la situación de forma envidiable. De la crisis, como dicen los economistas, “se saldrá y se volverá, todo es cíclico” y viendo la fortaleza que éste sector está mostrando unido a la necesidad de que nuestra economía abandone sectores muy deteriorados y sin una previsión positiva de futuro, la cosmética se postula con un futuro prometedor dentro del contexto económico español y europeo. “Vinci Cosmetics” es el nombre inicialmente pensado para que la nueva compañía inicie su andadura. Nombre con tintes latinos de la lejana época del imperio romano como homenaje a la rica herencia histórica de la ciudad del autor del proyecto - Tarragona. La cultura por cuidarse y sentirse bien, muy arraigada en la mentalidad latina y mediterránea, es un factor cultural clave para el desarrollo y futura evolución de esta industria. El slogan de la empresa, “Dieta Mediterránea para tu piel”, clarifica en buena medida la idea a desarrollar y los objetivos pretendidos por la estrategia empresarial. Objetivos: El objetivo esencial del TFC es elaborar un estudio detallado para la creación de una empresa de fabricación y comercialización de productos cosméticos de alta gama que abarque el management y la gestión por procesos de la empresa, la función de marketing, el tipo de operaciones y procesos a realizar, la gestión del factor humano y el presupuesto necesario para cubrir este ambicioso proyecto. En detalle, un completo plan de empresa que marque las directrices de la organización industrial que se pretende crear compuesto a su vez por cinco planes: plan de gerencia, plan de marketing, plan de operaciones, plan de recursos humanos y plan económico – financiero. Procedimientos: El proyecto tiene un alto componente de estudio de mercados y de marketing pero pretende también abarcar el management, los procesos de operación, el factor humano y el aspecto económico y financiero de las inversiones y presupuesto necesario. El estudio inicial centrará su esfuerzo en un análisis del mercado de la península ibérica, y, en función del avance y del progreso esperado por la empresa, la compañía podría extender su campo de acción a Europa aunque no antes de un medio plazo. “Vinci Cosmetics” ha adoptado referenciales de sistemas de gestión integrados en toda la organización. Así tenemos principalmente, por un lado, la norma internacional ISO 9001:2008 y, por otro, el Modelo EFQM de Excelencia en la gestión; ambos plasmados a partir de un enfoque basado en procesos que nos garantiza el control continuo y la gestión excelente. Conclusiones: Tras evaluar la situación actual del mercado de la cosmética, las previsiones futuras de éste y las necesidades que una organización industrial necesita, se puede crear - con plenas garantías de éxito como organización empresarial y desde el punto de vista económico - una empresa de cosméticos de alta gama para cubrir las necesidades de una parte de mercado que lo requiere.

Actualment a Catalunya existeixen zones amb importants limitacions per l’aplicació de purins al sòl, pel que és imprescindible trobar alternatives de gestió i tractament que permetin l’aprofitament adequat dels recursos continguts a les dejeccions ramaderes sense afectar el medi. La digestió anaeròbia és una de les tècniques utilitzades en el tractament de les dejeccions ramaderes. L’efluent líquid que s’obté d’aquest tractament no modifica el contingut de nitrogen i fòsfor i per tant ha de ser gestionat correctament. L’objectiu general d’aquest projecte és avaluar la precipitació d’estruvita (sal de magnesi, amoni i fosfat) com una alternativa de gestió de l’efluent líquid d’una planta de digestió anaeròbia i compostatge que tracta dejeccions ramaderes conjuntament amb altres residus orgànics. S’han avaluat els efectes dels diferents paràmetres operacionals en la formació d’estruvita (pH, temperatura, velocitat d’agitació, alcalinitat), mitjançant assaigs en discontinu amb solució sintètica. A continuació s’ha procedit a obtenir estruvita a partir de la fracció líquida digerida de purí (FLD), en assaigs en discontinu per estudiar l’efecte del contingut de matèria orgànica i sòlids Totals (ST), així com el contingut en fosfats i el pH de reacció. Finalment, s’han optimitzat els paràmetres de procés en continu, mitjançant la posada en marxa d’un reactor a escala de laboratori i estudi de l’efecte de la velocitat d’agitació i de la introducció del stripping de CO2, tant amb solució sintètica com amb la fracció líquida digerida del purí. Dels resultats obtinguts es pot concloure que els factors que tenen una major influència en el procés d’obtenció d’estruvita són el pH (el pH òptim es situa al voltant de 9), i la presència de matèria orgànica i sòlids ens suspensió, que interfereix de forma quantitativa i qualitativa en la formació de l’estruvita. En el procés en continu s’ha aconseguit reduccions d’un 84% i 98% d’amoni i fòsfor respectivament, obtenintse estruvita que pot ser utilitzada com a fertilitzant d’alliberació lenta. Es pot concloure que la precipitació d’estruvita és una bona alternativa per millorar la gestió de les dejeccions ramaderes alhora que permet recuperar nutrients i tancar cicles. La combinació amb un tractament previ que elimini la matèria orgànica, com podria ser la digestió anaeròbia, i una separació de fases, per eliminar els sòlids en suspensió, es presenta com una configuració amb molts avantatges.

La empresa moderna, se encuentra en una situación actual de incertidumbre en la que además está más expuesta a factores externos con el aumento de la competencia y el impacto de la globalización. Se enfrenta a un panorama que debe ser gestionado adecuadamente para asegurar su supervivencia y el éxito de su existencia. En este TFC, se presenta una de las herramientas ‘buque insignia’ del Management moderno, aquella que está destinada a ser la base de la Gestión de la empresa y que cada vez más se hace imprescindible para la construcción de un futuro cada vez más incierto, la Planificación Estratégica. El Plan Estratégico 2012-2015 de AESL se desarrolla en varios apartados que intentarán dar con las claves de la dirección que la empresa debe seguir y propone los objetivos que encontrará a través de la puesta en marcha de las acciones y estrategias determinadas. La primera etapa, y la más extensa, realiza un Análisis de la situación externa e interna de la empresa además de un Diagnóstico de la misma. Se analizan diversos factores que pueden contribuir o hacer peligrar el futuro de la empresa, y constituye el punto de partida de la planificación. En la segunda etapa, y con la información de la anterior fase, comienza la fijación de los Objetivos Corporativos y la definición de las Decisiones Estratégicas que han de transformar nuestro rumbo actual en el logro de esos objetivos. Las estrategias no sólo comportarán un ámbito corporativo, también se centrarán en estrategias funcionales con un carácter más definitorio en el interior de la empresa. Por último, la tercera y última etapa, aglutinará todas estas Decisiones estratégicas para transformarlas en las Decisiones Operativas, aquellas que se encargarán de gestionar el día a día de la empresa a través de los Planes de Acción, que suponen la etapa de mayor concreción del Plan. Este Plan a 3 años deberá erigirse como la herramienta de planificación más importante de la empresa, debiendo guiar las principales decisiones tomadas y convirtiéndose en un instrumento de consulta no sólo para decidir hoy lo que se hará en el futuro sino también para mantener unos niveles altos de competitividad en el tremendo esfuerzo que supone la gestión de una PYME.

In the field of observational methodology the observer is obviously a central figure, and close attention should be paid to the process through which he or she acquires, applies, and maintains the skills required. Basic training in how to apply the operational definitions of categories and the rules for coding, coupled with the opportunity to use the observation instrument in real-life situations, can have a positive effect in terms of the degree of agreement achieved when one evaluates intra- and inter-observer reliability. Several authors, including Arias, Argudo, & Alonso (2009) and Medina and Delgado (1999), have put forward proposals for the process of basic and applied training in this context. Reid y De Master (1982) focuses on the observer's performance and how to maintain the acquired skills, it being argued that periodic checks are needed after initial training because an observer may, over time, become less reliable due to the inherent complexity of category systems. The purpose of this subsequent training is to maintain acceptable levels of observer reliability. Various strategies can be used to this end, including providing feedback about those categories associated with a good reliability index, or offering re-training in how to apply those that yield lower indices. The aim of this study is to develop a performance-based index that is capable of assessing an observer's ability to produce reliable observations in conjunction with other observers.

The present thesis investigated the importance of semantics in generating inferences during discourse processing. Three aspects of semantics, gender stereotypes, implicit causality information and proto-role properties, were used to investigate whether semantics is activated elaboratively during discourse comprehension and what its relative importance is in backward inferencing compared to discourse/structural cues. Visual world eye-tracking studies revealed that semantics plays an important role in both backward and forward inferencing: Gender stereotypes and implicit causality information is activated elaboratively during online discourse comprehension. Moreover, gender stereotypes, implicit causality and proto-role properties of verbs are all used in backward inferencing. Importantly, the studies demonstrated that semantic cues are weighed against discourse/structural cues. When the structural cues consist of a combination of cues that have been independently shown to be important in backward inferencing, semantic effects may be masked, whereas when the structural cues consist of a combination of fewer prominent cues, semantics can have an earlier effect than structural factors in pronoun resolution. In addition, the type of inference matters, too: During anaphoric inferencing semantics has a prominent role, while discourse/structural salience attains more prominence during non-anaphoric inferencing. Finally, semantics exhibits a strong role in inviting new inferences to revise earlier made inferences even in the case the additional inference is not needed to establish coherence in discourse. The findings are generally in line with the Mental Model approaches. Two extended model versions are presented that incorporate the current findings into the earlier literature. These models allow both forward and backward inferencing to occur at any given moment during the course of processing; they also allow semantic and discourse/structural cues to contribute to both of these processes. However, while the Mental Model 1 does not assume interactions between semantic and discourse/structural factors in forward inferencing, the Mental Model 2 does assume such a link.

In the paper Busaniche and Cignoli (2009) we presented a quasivariety of commutative residuated lattices, called NPc-lattices, that serves as an algebraic semantics for paraconsistent Nelson's logic. In the present paper we show that NPc-lattices form a subvariety of the variety of commutative residuated lattices, we study congruences of NPc-lattices and some subvarieties of NPc-lattices.

Contemporary logic is confined to a few paradigmatic attitudes such as belief, knowledge, desire and intention. My purpose is to present a general model-theoretical semantics of propositional attitudes of any cognitive or volitive mode. In my view, one can recursively define the set of all psychological modes of attitudes. As Descartes anticipated, the two primitive modes are those of belief and desire. Complex modes are obtained by adding to primitive modes special cognitive and volitive ways or special propositional content or preparatory conditions. According to standard logic of attitudes (Hintikka), human agents are either perfectly rational or totally irrational. I will proceed to a finer analysis of propositional attitudes that accounts for our imperfect but minimal rationality. For that purpose I will use a non standard predicative logic according to which propositions with the same truth conditions can have different cognitive values and I will explicate subjective in addition to objective possibilities. Next I will enumerate valid laws of my general logic of propositional attitudes. At the end I will state principles according to which minimally rational agents dynamically revise attitudes of any mode.

The use of fertilizers and solid amendments in agriculture generates special interest for their effect on crop productivity, as well as for their environmental impact. The efficient use of these products demands knowing their physical and mechanical properties, the storing conditions effect and the operational characteristics of the metering systems used in the fertilizing equipment. In this context, the present study was developed with the purpose of evaluating the operational characteristics of different fertilizing metering systems and to determine the adequate metering system-product operational parameters, using powder lime, powder gypsum, granular 10-30-10 (N-P-K), and granular urea. Operational differences were established among four types of commercial fertilizer metering systems, including wire auger, star-shaped feed wheel, feed screw and ridged traction wheel. The study found that the unloading rate depends directly on the fertilizer metering system's rotating speed and is affected by particle size, repose angle, bulk density and moisture content of the applied product. The wire auger and star-shaped feed wheel metering systems were adequate for the distribution of powder products and the feed screw for granulated fertilizers. Furthermore, theoretical and experimental characteristic equations were established, defining curves for calibration and handling of the products plus the rotating speed range in which a better distributing behavior was achieved.

Potato is an important crop plant throughout the world. Harvesting is a fundamental step in its production system. Maybe, it is the most complex and expensive operation. Thus, the objective of this work was to compare the cost of the mechanized and semi-mechanized harvest, the operational capacity and the production losses during the potato harvest process. The work was accomplished in a commercial farming, cultivated under pivot system, in the municipal district of Perdizes - MG, Brazil. A completely randomized design with two treatments was used: mechanized and semi-mechanized harvest. The mechanized harvest used a self-propelled harvester. In the semi-automated harvest, a digger mounted on tractor was used and the potato was manually harvested. It was concluded that the cost of mechanized harvest was 49.03% lower than the cost of semi-mechanized harvest. On average, the harvester had a work for 23 workers in manual harvest. Mechanized harvest showed losses of 2.35% of potato yield, while the semi-mechanized harvest showed losses of 6.32%.

The use of no tillage system associated with the crop-livestock integration is an alternate managing that promotes the accumulation of dry matter in the soil, an essential fact to make the system sustainable and profitable. The aim of this study was to evaluate the operational performance of a planter-tractor set on maize straws intercropped with Urochloa, in different seeding modes. The soybean crop was seed on the intercropping of two forage species (Urochloa brizantha and Urochloa ruziziensis) in five cropping systems: MBL (Maize with Urochloa in the maize seeding row, mixed with base fertilizer and deposited at 0.10 m), MBE (Maize with Urochloa seeded between rows at the same day of seeding maize), MBC (Urochloa between rows of maize seeded with the covering fertilizer at the V4 stage), MBLA (Maize with Urochloa by broadcast seeding at the V4 stage ) and MS (Single Maize: control). The following variables were evaluated: dry mass of maize straw, dry mass of forages and total dry mass of straw; and for the operational parameters the speed of seeding, wheel slippage, traction force and average power at the drawbar. The results showed that the amount of straw produced by maize intercropping with Urochloa, interferes in the operational performance of the tractor-planter at the operation of soybean seeding, i.e., areas with higher amount of straw promote greater energy demand, as well as higher wheel slippage.

Citrus orchards are very important in Brazil, especially in São Paulo State, where occupy an area of 600,000 ha approximately. To identify sustainability degree of citrus production system, an energy analysis allows evaluating efficiency of direct and indirect applied inputs. Thus, this study aimed to evaluate citrus production system under energetic point of view, in which invested energy is paid back with citrus production; being compared within three scenarios for operational field efficiency. As result, by sensitivity analysis was determined that fuel was the main energy demander, followed by pesticides and fertilizers. In operational work capacity analysis, all combinations between efficiency (minimum, typical and maximum) and yield levels became positive in the seventh year, except for the combination minimum efficiency and 10 % less yield, positive in the eighth year. The best combination (maximum efficiency and 10 % more yield) has promoted investment payoff around the sixth and seventh year. By this study, it is possible to determine the total energy demand to produce citrus and indentify the applied inputs that need more attention by the decision-makers. Labor and seedlings can be ommited for further studies with citrus, since they were irrelevant. Management of agricultural machinery may pose an important role on decreasing environmental impact of citrus production.

This master’s thesis aims to examine the relationship between dynamic capabilities and operational-level innovations. In addition, measures for the concept of dynamic capabilities are developed. The study was executed in the magazine publishing industry which is considered favourable for examining dynamic capabilities, since the sector is characterized by rapid change. As a basis for the study and the measure development, a literary review was conducted. Data for the empirical section was gathered by a survey targeted to chief-editors of Finnish consumer magazines. The relationship between dynamic capabilities and innovation was examined by multiple linear regression. The results indicate that dynamic capabilities have effect on the emergence of radical innovations. Environmental dynamism’s effect on radical innovations was not detected. Also, dynamic capabilities’ effect on innovation was not greater in turbulent operating environment.
