The teacher-student relationship is multidimensional and fluid. This is especially true for students who come from disadvantaged backgrounds. Educational leaders in the public school setting cannot control which students enroll at their school sites. The only thing teachers, as educational leaders in K-12 public education, have complete control over is the environment they create in their classrooms. Among those student groups most reflecting few gains on state and federal reports of proficiency data are students who typically come from backgrounds besieged with challenges or from historically underserved and marginalized communities. In this transcendental phenomenological study, the phenomenon investigated was how secondary teachers described their experiences in building relationships with students identified as at promise. A secondary public school setting was the focus of this study. The intent of this study was to understand the essence of the lived experiences of teachers as they described their experiences in building relationships with at-promise youth. Teachers must leverage themselves in the quest to form positive and strong relationships with their students. In shifting the adverse narrative about the political identity used to categorize these students, the antipathetic mindset related to these students in public schools too shall shift. Research has demonstrated that at-promise students respond best in school settings that provide a culture where teachers intentionally construct a caring interaction laden with respect and recognition. It is important to foster agency in at-promise students through the understanding of the social, political, and economic structures that served to impact their generational past, inform their present, and prepare their future. This research study focused on the complex dynamic of the teacher-student relationship. This research investigation connected the important role teachers play in the lives of their students, teacher mindset about at-promise student success, and how strong and positive teacher-student relationships have the potential to encourage agency in at-promise students through meaningful recognition of their promise for academic success over their presupposed risks. This study’s findings highlight the critical need for teachers to create intentional opportunities to foster strong teacher-student relationships with at-promise students.

This research provides information about Economic Development Zones (EDZ) to help the reader understand these programs. For a business owner they are able to make informed decisions about the merits of these programs and decide whether it makes sense for them to relocate their businesses to Florida’s Economic Development Zones. What most readers do not know is that these programs and the operating condition of an Economic Development Zone can offer benefits to a business owner, allowing them to reduce their operating expenses and the cost of doing business. Over the past several years, the researcher discussed foreign trade opportunities with different individuals. One of these conversations was with the sale director of a company located at Sebring Airfield and Intermodal Facility in Sebring, Florida. In this discussion, the benefits of locating a business in an Economic Development Zone, within an economically depressed rural area of Florida, was introduced. This conversation led to researching what it takes to relocate or operate a business in Economic Development Zones located in rural areas. The basic purpose in creating an EDZ through local, state, and federal government agencies is to reduce unemployment in depressed areas of the United States. This goal is accomplished by incentivizing businesses to create jobs and make capital investments in those areas. Different levels of government offer incentives to companies for relocating or expanding their businesses by creating Economic Zones. The incentives for relocating, expanding, or starting a business in an EDZ can be very lucrative. Businesses look for every opportunity to reduce their operating expenses by reducing the cost of doing business. Through incentives and tax breaks, a business could reduce its yearly operating costs making them more competitive. The goal of companies is to reduce their overhead and the government goal is to create jobs which should be mutually supportive, yet it is not the case. This lack of awareness is a major contributing factor for why these programs are not successful. From prior research conducted during a literature review, there is very little information about these programs beyond government webpages. With the rapid turnover of programs due to the political election cycle, there is little current information on the most recent EDZ except what is offered at the Federal level. One of the challenges in starting operations in an EDZ is the identification of the different stakeholders for federal, state and local programs. The lines of communication and the delineation of responsibilities between the federal government, state, and local development councils can be very confusing. In order to navigate between the different programs a business owner needs to understand how support flows down to the local agencies. An interest trend from this research, is a clear lack of awareness about these programs. Most business leaders are not aware of their local economic development office and only a few businesses had received any benefits from this organization. There is a need for better awareness about these opportunities. After reading these articles, a business leader is able to make informed decisions about the merits of these programs and decide whether it makes sense for them to relocate or expand their businesses to Florida’s Economic Development Zones.

Essay 1: (with Henrik Jordahl and Panu Poutvaara) We present and test a theory of prospective and retrospective pocketbook voting. Focusing on two large reforms in Sweden, we establish a causal chain from policies to sizeable individual gains and losses and then to voting. The Social Democrats proposed budget cuts affecting parents with young children before the 1994 election, but made generous promises to the same group before the 1998 election. Since parents with older children were largely unaffected we use a difference-in-differences strategy for identification. We find clear evidence of prospective pocketbook voting. Voters respond to campaign promises but not to the later implementation of the reforms. / Essay 2: This essay presents a detailed analysis of voters' response to municipality and regional level unemployment and economic growth, in Swedish general elections from 1985 to 2002, using data on 284 municipalities and 9 regions. The preferred specification suggests that an increase in regional growth or a reduction in regional unemployment by one percentage point is associated with an increase in the support for the national government by about 0.6 and 1.0 percentage points. Changes in unemployment and growth at the municipality level seem to have muchsmaller effects on government support. / Essay 3: One prediction from cognitive dissonance theory is that the act of voting makes people more positive toward the party or candidate they have voted for. Following Mullainathan and Washington (2008), I test this prediction by using exogenous variation in turnout provided by the voting age restriction. I improve on previous studies by investigating political attitudes, measured just before elections, when they are highly predictive of voting. In contrast to earlier studies I find no effect of voting on political attitudes. This result holds for a variety of political attitudes and data from both Sweden and the United States. / Essay4: (with Niclas Berggren and Henrik Jordahl) We conduct an extensive robustness analysis of the relationship between trust and growth by investigating a later time period and a bigger sample than in previous studies. In addition to robustness tests that focus on model uncertainty, we systematize the investigation of outlier influence on the results by using the robust estimation technique Least Trimmed Squares. We find that when outliers (especially China) are removed, the trust-growth relationship is no longer robust. On average, the trust coefficient is half as large as in previous findings.

The role of best practice in delivering Company Strategy-Brand Promise delivering "Escape through Glamour," has become an issue for the management of Ster-Kinekor as the competitive set in the entertainment arena, increases and becomes aggressive. This has compounded by the digital explosion which has made home entertainment sexy and raised the benchmark of picture and sound quality. Prices are extremely competitive and this practice is supported by the criminal element, i.e. Piracy. The increase in live and televised sports entertainment, television entertainment in general and outdoor activities has contributed to the pressure in growing revenue. Ster-Kinekor has identified the new middle income segment as an opportunity for growth and has identified perceived value of the entertainment format as a key barrier. This is true for the Living Standard Measures (hereafter, LSM) 8, 9 and 10 segment of the market as well. The need to increase the perceived value of the brand and the entertainment it offers has been identified as a key issue by senior management. This study will highlight the concepts of branding and best practice within a review of Ster-Kinekor operational (best practice) interventions. This will be followed by a detailed analysis and interpretation of 800 intercept interviews which will inform the study concerning the market impact of the interventions. In addition, informal interviews were held with various members of management. Ster-Kinekor has introduced a number of initiatives, including a number of best practice interventions under a project entitled "Good to Great." This interventions are aimed at installing best practice within the business with the overall intention of improving customer experience and thereby driving the bottom line. The study therefore will analyse the impact of this these initiatives as intended by Ster-Kinekor management. In conclusion, the study will provide recommendations for consideration in order to enhance the perceived value. / Thesis (MBA)-University of KwaZulu-Natal, Westville, 2006.

Esta dissertação tem por objetivo analisar o contrato preliminar, a partir das diversas funções que ele cumpre no processo de formação do negócio jurídico. Em especial, examina-se a figura do contrato preliminar que é menos completo do que o contrato definitivo, estabelecendo apenas os aspectos essenciais do negócio prometido e deixando em aberto outros pontos que devem ser preenchidos no intervalo entre os dois negócios. O contrato preliminar incompleto, como se lhe designa aqui, constitui uma etapa no processo de formação progressiva do contrato, atendendo a interesses dignos de tutela conforme o ordenamento jurídico. Para tanto, o trabalho está dividido em quatro capítulos, além da introdução e da conclusão. Na primeira parte, apresentam-se os principais interesses práticos que estão por trás da cisão do negócio em duas etapas (no contrato preliminar e no contrato definitivo). Vê-se que o contrato preliminar não é uma figura inútil, um desdobramento desnecessário do processo de formação do negócio. Na segunda parte, são delineados os contornos do contrato preliminar, mediante o exame de sua causa e de seu objeto, além das figuras que se lhe assemelham. Demonstra-se que, embora não se confunda com o negócio definitivo, o contrato preliminar já deve definir a causa do negócio prometido, que serve para identificá-lo. Na terceira parte, atenta-se para o chamado princípio da equiparação, que determina que, em regra, o contrato preliminar siga a mesma disciplina prevista para o negócio definitivo. Tal princípio deve ser, todavia, excepcionado, quando a própria cisão do processo de formação do negócio no preliminar e no definitivo serve para afastar alguma regra que valerá apenas para o segundo negócio. Nesse ponto, demonstra-se que o princípio da equiparação não se aplica integralmente no que se refere ao objeto do contrato definitivo, que não precisa estar previsto, exaustivamente, no contrato preliminar. Revela-se, aí, a admissibilidade da figura do contrato preliminar incompleto. Por fim, na última parte, examina-se a execução específica do preliminar, destacando-se, em particular, o cabimento desse remédio também para o chamado contrato preliminar incompleto, quando, então, caberá ao juiz integrá-lo mediante as regras de integração previstas no ordenamento jurídico. / The objective of this dissertation is to analyze preliminary contracts in the light of the various functions they perform in the formation of a legal transaction. In particular, the paper examines preliminary contracts which are less complete than the definitive contracts they precede and which set out merely the essential aspects of the promised transaction, leaving other points to be decided upon in the interval between the two contracts. Such contracts, referred to in this paper as incomplete preliminary contracts, constitute a distinct stage in the process of progressive formation of the legal transaction and address interests which are capable, in our legal system, of giving rise to a claim for judicial relief. This study is divided into four chapters (in addition to the introduction and conclusion). The first part sets out the principal practical interests behind the splitting of a legal transaction into two distinct parts (the preliminary contract and the definitive contract) and demonstrates that the preliminary contract is by no means an unnecessary and useless offshoot of the formation of a legal transaction. The second part sets out an overview of preliminary contracts in terms of their raison dêtre and their objects and draws a parallel with other similar legal instruments. This part seeks to show that despite being distinct from the definitive contract, the preliminary contract defines the raison dêtre of the promised transaction (i.e. the reason for contracting) and thus serves to define (classify) the contract. In the third part, attention is drawn to the so-called principle of equivalence (principio de equiparação) according to which a preliminary contract must, as a general rule, comply with the same legal rules applicable to the definitive agreement. An exception needs to be made, however, when the actual separation of the process of formation of the legal transaction into preliminary and definitive stages leads to a given rule being applicable solely to the definitive contract. The author demonstrates that, in such cases, the principle of equivalence does not apply in full to the objects of the definitive contract and said objects do not therefore need to be the subject of exhaustive provision in the preliminary contract. This therefore reveals that an incomplete preliminary contract is legally permissible. Finally, in the closing part of the paper, the issue of specific performance of the preliminary contract is examined. Particular emphasis is given to the applicability of this legal remedy to incomplete preliminary agreements and to the powers vested in the judge to complete (i.e. fill in the gaps) in the preliminary contract, in accordance with the applicable rules as to integration of contracts

The author of the Fourth Gospel delivers the true divine identity and significance of Jesus throughout the entire narrative. He aims at guiding his readers through the narrative of the Gospel with the purpose that they will “see” (meet) Jesus, confess him as Christ, and receive eternal life. John actually planned that the text of the Gospel should actively change people. Furthermore, the Gospel of John has wide spectrum of the reader. This means that John opens his message to the all the generations who are no longer in a position to see Jesus physically. Nobody reading this text should or could stay the same, since he or she will be confronted with the protagonist of the text, namely Jesus. By accepting this message, that person will receive life; by rejecting the message, a person will perish. This truth is rehearsed over and again in the narrative for every reader to see. The text of the Gospel thus becomes the “presence of Jesus” among the readers. This functional purpose of the Gospel accounts for the first farewell discourse in John 13:31-14:31. In response to previous scholarship that understands the Johannine farewell discourses solely as a testament, the present study convinces that the discourses interface with classical literature, specifically the following literary styles: Greek tragedy, consolation literature, and the literary symposium tradition. The multiplicity of the generic associations of the discourses sheds new light on the nature of Jesus’ departure as well as his continuing presence in spite of that departure. No longer designed to evoke only the themes of departure and absence, the testament of Jesus in John emphasises instead Jesus’ abiding presence. While the material from Greek tragedy will only further emphasise the theme of departure, the material from classical consolation literature and the literary symposium tradition will accentuate the theme of continuing presence. John has thereby transcended the usual expectations of the testament. Thus the physically absent Jesus becomes present through his first farewell discourse: the reader is confronted with a dynamic portrait of Jesus and this confrontation results in an acceptance of Jesus as Christ, as well as the receiving of eternal life. According to the first farewell discourse, eschatological promise, knowing and seeing the Father, glory, love, pastoral ministry, deeds, prayer, Paraclete, remembering, faith, peace and joy, and the words of Jesus all serve as the replacement of the physical Jesus. Therefore, the first farewell discourse does not indicate the separation of Jesus from his disciples but rather the permanent presence of the risen Jesus in and among them. This is their basis for perseverance, in other words, the foundation of their spreading the gospel messages to non-believers, even though they were in a difficult place. the gospel of John, John 13:31-14-31, the purpose of John’s gospel, the presence of Jesus, the recipient of the Fourth Gospel, the farewell discourse(s), Biblical hermeneutics, glory, eschatological promise, the Paraclete, mutual love, peace and joy / Thesis (PhD (New Testament Studies))--University of Pretoria, 2007. / New Testament Studies / unrestricted

Bien que la science n’ait pas encore percé les secrets de la conscience humaine, les avancées dans le domaine de l’intelligence artificielle ont provoqué une résurgence du mythe de la créature artificielle dans le domaine de l’imaginaire. Ce mémoire vise à comprendre l’actualisation de ce mythe antique par la promesse scientifique contemporaine et son incarnation dans l’imaginaire cinématographique de science-fiction. Après un retour historique sur l’évolution du domaine de l’IA, j’insisterai sur le rôle joué par le cinéma de science-fiction dans sa capacité à construire un imaginaire scientifique crédible. Je me concentre sur le mythe antique de la créature artificielle pour ensuite mettre en évidence le point où il rencontre la science par l’usage du medium cinématographique, capable de transmettre cet « ailleurs » contenu dans la promesse scientifique et matérialisé par la science-fiction. Afin de rendre compte de cette actualisation, je forme un corpus de films en prenant soin de retracer la généalogie conjointe de l’évolution scientifique de l’IA et de sa projection dans l’imaginaire par la mise en parallèle dans l’analyse de l’actualité de la recherche technoscientifique au moment de la parution de chaque film du corpus. Par cette méthode j’arrive à liste suivante : Frankenstein (1931) ; 2001, A Space Odyssey (1968) ; Blade Runner (1982) ; Terminator 2 (1991) ; A.I : Artificial Intelligence (2001) ; Her (2013) ; Ex Machina (2015) ; Blade Runner 2049 (2017). Cette disposition me permet de constater l’évolution de la promesse de l’IA forte en prise avec la discussion que le réel entretient avec l’imaginaire du mythe de la créature artificielle. Par l’analyse des technologies qui sous-tendent la création de chacune de ces créatures, j’analyse la manière par laquelle la science-fiction matérialise la promesse scientifique d’une IA forte, et cela avant même l’érection de son domaine consacré (i.e. Frankenstein). Deux films ont cependant résisté à mon cadre d’analyse, Blade Runner et Blade Runner 2049, en offrant une histoire alternative de l’IA à partir d’une créature artificielle non pas entièrement technique mais cyborg, à l’interstice de notre monde biologique et celui de la machine. / Although science has yet to unlock the secrets of human consciousness, recent advances in Artificial Intelligence research have caused the myth of the artificial creature to resurface in the realm of the imaginary. This dissertation aims to understand the actualization of this ancient myth through the contemporary scientific promise of AI and its incarnation in the cinematic science fiction imagination. After a historical review of the evolution of the field of research in AI, I insist on the role played by science fiction cinema in its ability to build a credible scientific imagination. I then come back to the imaginary of the myth of the artificial creature to highlight the point where it meets science through the use of the medium of cinema, capable of transmitting this "elsewhere" contained in the scientific promise and materialize it through science fiction. I form a corpus of seven films retracing the joint genealogy of the scientific evolution of AI and its projection into the imagination by comparing it in the analysis of current events of technoscientific research at the time of the release of each film in the corpus. By this method I arrive at the following list: Frankenstein (1931); 2001, A Space Odyssey (1968); Blade Runner (1982); Terminator 2 (1991); A.I: Artificial Intelligence (2001); Her (2013); Ex Machina (2015); Blade Runner 2049 (2017). This allows me to describe the evolution of the promise of strong AI in the discussion that the real entertains with the imaginary of the myth of the artificial creature. By focusing on the technologies which underlie the creation of each of these creatures, I am able to analyze how science fiction materializes the scientific promise of a strong AI, and this even before the erection of its consecrated domain (i.e. Frankenstein). However, two films withstood our analytical framework, Blade Runner and Blade Runner 2049, by offering an alternate story of AI from an artificial creature not entirely technical but cyborg, at the interstice of our biological world and that of the machine.

Tesis por compendio / The Lack of Homogeneity in the Product (LHP) appears in productive processes with raw materials, which directly stem from nature and/or production processes with operations that confer heterogeneity to the characteristics of the outputs obtained, even when the inputs used are homogeneous. LHP appears in different sectors such as ceramic tile, horticulture, marble, snacks, among others. LHP becomes a managerial problem when customers require to be served with homogeneous product. Supply chains responsible to provide homogeneous product face the need to include classification activities in their productive processes to obtain sub-lots of homogeneous product. Due to the inherent LHP uncertainty, these homogeneous sub-lots will not be known until the product have been produced and classified. An improper management of the LHP can have a very negative impact on the customers' satisfaction due to inconsistencies in the answer to their requirements and also on the Supply Chain's efficiency. The Order Promising Process (OPP) appears as a key element for properly managing the LHP in order to ensure the matching of uncertain homogeneous supply with customer order proposals. The OPP refers to the set of business activities that are triggered to provide a response to the orders from customers. These activities are related to the acceptance/rejection decision, and to set delivery dates. For supply chains affected by the LHP, the OPP must consider the homogeneity as another requirement in the answer to the orders. Besides, due to the LHP inherent uncertainty, discrepancies between the real and planned homogeneous quantities might provoke that previously committed orders cannot be served. The Shortage Planning (SP) process intends to find alternatives in order to minimise the negative impact on customers and the supply chain. Considering LHP in the OPP brings a set of new challenging features to be addressed. The conventional approach of assuming homogeneity in the product for the master production schedule (MPS) and the quantities Available-To-Promise (ATP) derived from it is no longer adequate. Instead, both the MPS and ATP should be handled in terms of homogeneous sub-lots. Since the exact quantity of homogeneous product from the planned lots in the MPS is not exactly known until the classification activities have been performed, the ATP also inherits this uncertainty, bringing a new level of complexity. Non-homogeneous product cannot be accumulated in order to fulfil future incoming orders. Even more, if the product handled is perishable, the homogeneity management becomes considerably more complex. This is because the state of the product is dynamic with time and related variables to it, like quality, price, etc., could change with time. This situation could bring unexpected wasting costs apart from the shortages already mentioned. The perishability factor is itself another source of uncertainty associated to the LHP. This dissertation proposes a conceptual framework and different mathematical programming models and tools, in both deterministic and uncertainty environments, in order to support the OPP and SP under LHP's effect. The aim is to provide a reliable commitment with customer orders looking for a high service level not just in the due date and quantity but also in the homogeneity requirements. The modelling of the characteristics inherent to LHP under deterministic context constitutes itself one of the main contribution of this dissertation. Another novelty consists in the inclusion of uncertainty in the definition of homogeneous sub-lots, their quantities and their dynamic state and value. The uncertainty modelling approach proposed is mainly based on the application of fuzzy set theory and possibility theory. The proposed mathematical models and tools have been validated in real cases of SC, specifically in the ceramic tile sector for non perishables, and in the fruit sector for perishables. The results show a ... / La Falta de Homogeneidad en el Producto (LHP, por sus siglas del inglés ``Lack of Homogeneity in the Product'') aparece en procesos productivos con materias primas que derivan directamente de la naturaleza y/o procesos de producción con operaciones que confieren heterogeneidad a las características de los productos obtenidos, incluso cuando los insumos utilizados son homogéneos. La LHP aparece en diferentes sectores como la cerámica, horticultura, mármol, snacks, entre otros. Se convierte en un problema gerencial cuando los clientes requieren homogeneidad en el producto y las cadenas de suministro enfrentan la necesidad de incluir actividades de clasificación en sus procesos productivos para obtener sub-lotes de producto homogéneo. Debido a la incertidumbre inherente a la LHP, los sub-lotes homogéneos y su cantidad no serán conocidos hasta que el producto haya sido producido y clasificado. Una gestión inadecuada de la LHP puede tener un impacto muy negativo en la satisfacción de los clientes debido a inconsistencias en la respuesta a sus requerimientos y también en la eficacia de la Cadena de Suministro. El Proceso de Comprometer de Pedido (OPP, por sus siglas del inglés ``Order Promising Process'') aparece como un elemento clave para gestionar adecuadamente la LHP, con el fin de asegurar la coincidencia entre el suministro incierto de producto homogéneo y las propuestas de pedido del cliente. El OPP se refiere al conjunto de actividades empresariales realizadas para proporcionar una respuesta a las órdenes de los clientes. Estas actividades están relacionadas con las decisiones de aceptación/rechazo, y establecimiento de fechas de entrega para las órdenes del cliente. En las cadenas de suministro afectadas por la LHP, el OPP debe considerar la homogeneidad como otro requisito adicional en la respuesta a los pedidos. Además, debido a la incertidumbre intrínseca de la LHP, las discrepancias entre las cantidades homogéneas reales y planificadas podrían provocar que las órdenes comprometidas anteriormente no puedan ser completadas debido a la escasez de producto. El proceso de planificación de la escasez (SP, por sus siglas del inglés "Shortage Planning") se encarga de encontrar alternativas para minimizar este impacto negativo en los clientes y la cadena de suministro. Considerar la LHP dentro del OPP implica un conjunto nuevo de características desafiantes que deben ser abordadas. El enfoque convencional de asumir la homogeneidad en el producto para el programa maestro de producción (MPS, por sus siglas del inglés "Master Production Schedule") y las cantidades disponibles a comprometer (ATP, por sus siglas del inglés "Available-To-Promise") derivadas de él, no es adecuado. En cambio, tanto el MPS como el ATP deben manejarse en términos de sub-lotes homogéneos. Dado que la cantidad exacta de producto homogéneo de los lotes previstos en el MPS no se sabe exactamente hasta que se han realizado las actividades de clasificación, el ATP también hereda esta incertidumbre, trayendo un nuevo nivel de complejidad. El producto no homogéneo no se puede acumular para satisfacer futuras órdenes entrantes. Más aún, si el producto manipulado es perecedero, el manejo de la homogeneidad se vuelve mucho más complejo. Esto se debe a que el estado del producto es dinámico en el tiempo, y variables relacionadas como calidad, precio, etc., podrían también cambiar con el tiempo. Esta situación puede provocar costos inesperados de desperdicio aparte de la escasez ya mencionada. El factor de perecedero es en sí mismo otra fuente de incertidumbre asociada a la LHP. Esta disertación propone un marco conceptual y diferentes modelos y herramientas de programación matemática, tanto en entornos deterministas como de incertidumbre, para apoyar al OPP y SP considerando el efecto de LHP. El objetivo es proporcionar un compromiso fiable con los pedidos de los clientes en busca de un alto nivel de servicio no s / La Falta d'Homogeneïtat en el Producte (LHP, per les seues sigles de l'anglés ''Lack of Homogeneity in the Product'') apareix en processos productius amb matèries primes que deriven directament de la natura i/o processos de producció amb operacions que conferixen heterogeneïtat a les característiques dels productes obtinguts, fins i tot quan les entrades utilitzades són homogènies .

A causa de la incertesa inherent a la LHP, els sublots homogenis i la seua quantitat no seran coneguts fins que el producte haja sigut produït i classificat. Una gestió inadequada de la LHP pot tindre un impacte molt negatiu en la satisfacció dels clients degut a inconsistències en la resposta als seus requeriments i també en l'eficàcia de la Cadena de Subministrament. El Procés de Comprometre Comandes (OPP, per les seues sigles de l'anglés ''Order Promising Process'') apareix com un element clau per a gestionar adequadament la LHP, a fi d'assegurar la coincidència entre el subministrament incert de producte homogeni i les propostes de comanda del client. L'OPP es refereix al conjunt d'activitats empresarials realitzades per a proporcionar una resposta a les ordres dels clients. Aquestes activitats estan relacionades amb les decisions d'acceptació/rebuig, i establiment de dates de lliurament per a les ordres del client. En les cadenes de subministrament afectades per la LHP, l'OPP ha de considerar l'homogeneïtat com un altre requisit addicional en la resposta a les comandes. A més, a causa de la incertesa intrínseca de la LHP, les discrepàncies entre les quantitats homogènies reals i planificades podrien provocar que les ordres compromeses anteriorment no puguen ser completades a causa de l'escassetat de producte. El procés de planificació de l'escassetat (SP, per les seues sigles de l'anglés "Shortage Planning") s'encarrega de trobar alternatives per a minimitzar aquest impacte negatiu en els clients i en la cadena de subministrament. Considerar la LHP dins de l'OPP implica un conjunt nou de característiques desafiants que han de ser abordades. L'enfocament convencional d'assumir l'homogeneïtat en el producte per al programa mestre de producció (MPS, per les seues sigles de l'anglés "Master Production Schedule") i les quantitats disponibles a comprometre (ATP, per les seues sigles de l'anglés "Available-To-Promise") derivades d'ell, no és adequat. En canvi, tant el MPS com l'ATP han de manejar-se en termes de sublots homogenis. Atés que la quantitat exacta de producte homogeni dels lots previstos en el MPS no se sap exactament fins que s'han realitzat les activitats de classificació, l'ATP també hereta aquesta incertesa, portant un nou nivell de complexitat. El producte no homogeni no es pot acumular per a satisfer futures ordees entrants. Més encara, si el producte manipulat és perible, el maneig de l'homogeneïtat es torna molt més complex. Açò es deu al fet que l'estat del producte és dinàmic en el temps, i variables relacionades com qualitat, preu, etc., podrien també canviar amb el temps. Aquesta situació pot provocar costos inesperats de rebuig a banda de l'escassetat ja esmentada. El factor de perible és en si mateix un altra font d'incertesa associada a la LHP. Aquesta dissertació proposa un marc conceptual i diferents models i eines de programació matemàtica, tant en entorns deterministes com d'incertesa, per a recolzar a l'OPP i SP considerant l'efecte de LHP. L'objectiu és proporcionar un compromís fiable amb les comandes dels clients a la recerca d'un alt nivell de servei no sols en la data i la quantitat esperades, s / Grillo Espinoza, H. (2017).
