Análise das relações entre estratégia de produção, práticas e desempenho operacional

Este trabalho teve o objetivo de verificar quais são as melhores práticas de produção para o setor moveleiro no Brasil, mediante a análise das relações entre as práticas de produção implantadas e prioridades competitivas e, também, entre indicadores de desempenho. A revisão teórica centrou em definir o pressuposto para o estudo das melhores práticas e realizar uma sistematização da literatura. Posteriormente, foi desenvolvida a pesquisa prática mediante uma survey em 99 empresas. Para a análise dos dados, foi empregada a técnica de modelagem de equações estruturais com o método de estimação dos mínimos quadrados ponderados. Os resultados revelaram que as práticas nas áreas de desenvolvimento de novos produtos, recursos humanos e planejamento e controle de produção estavam alinhadas à estratégia de produção e contribuíram para a melhoria de indicadores de desempenho operacional, sendo assim consideradas melhores práticas para o contexto estudado. Foram feitas discussões e sugestões para pesquisas futuras.

Riconversione degli impianti saccariferi per la valorizzazione della filiera agro-energetica: analisi di impatto sul comprensorio agricolo

Il presente lavoro trae origine dagli obiettivi e dalle relative misure applicative della riforma dell’OCM zucchero del 2006 e nello specifico dal Piano nazionale per la razionalizzazione e riconversione della produzione bieticolo-saccarifera approvato dal MIPAF nel 2007. Lo studio riguarda la riconversione dello zuccherificio di Finale Emilia (MO), di appartenenza del Gruppo bieticolo-saccarifero Co.Pro.B, in un impianto di generazione di energia elettrica e termica che utilizza biomassa di origine agricola per la combustione diretta. L'alimentazione avviene principalmente dalla coltivazione dedicata del sorgo da fibra (Sorghum bicolor), integrata con risorse agro-forestali. Lo studio mostra la necessità di coltivazione di 4.400 ettari di sorgo da fibra con una produzione annua di circa 97.000 t di prodotto al 75% di sostanza secca necessari per l’alimentazione della centrale a biomassa. L’obiettivo é quello di valutare l’impatto della nuova coltura energetica sul comprensorio agricolo e sulla economia dell’impresa agricola. La metodologia adottata si basa sulla simulazione di modelli aziendali di programmazione lineare che prevedono l’inserimento del sorgo da fibra come coltura energetica nel piano ottimo delle aziende considerate. I modelli predisposti sono stati calibrati su aziende RICA al fine di riprodurre riparti medi reali su tre tipologie dimensionali rappresentative: azienda piccola entro i 20 ha, media da 20 a 50 ha e grande oltre i 50 ha. La superficie di entrata a livello aziendale, se rapportata alla rappresentatività delle aziende dell’area di studio, risulta insufficiente per soddisfare la richiesta di approvvigionamento dell’impianto a biomassa. Infatti con tale incremento la superficie di coltivazione nel comprensorio si attesta sui 2.500 ettari circa contro i 4.400 necessari alla centrale. Lo studio mostra pertanto che occorre un incentivo superiore, di circa 80-90 €/ha, per soddisfare la richiesta della superficie colturale a livello di territorio. A questi livelli, la disponibilità della coltura energetica sul comprensorio risulta circa 9.500 ettari.

Arte e design in Italia dalla metà degli anni Sessanta alle ultime tendenze

Il lavoro di ricerca è rivolto ad indagare l’emersione di schemi di variazione comuni all’arte e al design, limitatamente al contesto italiano e in un arco di tempo che va dalla metà degli anni Sessanta del secolo scorso a oggi. L’analisi vuole rintracciare, mediante l’applicazione della metodologia fenomenologica, un sentire condiviso tra le due discipline e, nel pieno rispetto dei relativi linguaggi e con nessuna volontà di sudditanza degli uni rispetto agli altri, individuare i rapporti di corrispondenza omologica capaci di mettere in luce lo spirito del tempo che le ha generate. La ricerca si pone l’obiettivo di estendere gli studi sul contemporaneo attraverso un’impostazione che intende applicare gli strumenti metodologici della critica d’arte all’evoluzione stilistica delle tendenze del design italiano. Non si è voluto redigere una “storia” del design italiano ma, considerata anche l’ampiezza dell’argomento, si è necessariamente proceduto a delimitare il territorio di applicazione scegliendo di prendere in considerazione il solo settore del design dell’arredo. Si è dunque optato per una visione globale delle vicende del design del prodotto, tesa ad indagare gli snodi principali, concentrando pertanto l’analisi su alcuni protagonisti della cultura del progetto, ossia su quelle figure risultate dominanti nel proprio tempo perché capaci con il loro lavoro di dare un contribuito determinante alla comprensione delle fasi evolutive del design italiano. Gli strumenti utili a condurre l’analisi provengono principalmente dalla metodologia binaria individuata dallo storico dell’arte Heinrich Wölfflin e dagli studi di Renato Barilli, il cui impianto culturologico ha fornito un indispensabile contributo al processo di sistematizzazione dei meccanismi di variazione interni alle arti; sia quelli di tipo orizzontale, di convergenza reciproca con gli altri saperi, che di tipo verticale, in rapporto cioè con le scoperte scientifiche e tecnologiche della coeva cultura materiale.

Die Problematik des sogenannten Bettpaneels von Ugarit

Gegenstand meiner Arbeit ist das Bettpaneel von Ugarit und seine komplexe Ikonographie, die Motive unterschiedlicher künstlerischer Traditionen des Alten Orients vereint. Das Bettpaneel bietet die einmalige Gelegenheit, das gesamte Bildprogramm eines Möbels zu untersuchen und die Entwicklung des levantinischen Kunsthandwerks der Späten Bronzezeit (2. Hälfte des 2. Jt.s v. Chr.) besser zu verstehen, besonders in Bezug auf Prestigegüter. Bereits 1952 ist das Bettpaneel im Königspalast von Ugarit entdeckt, jedoch bisher noch nicht monographisch abhandelt worden.rnEs wird gezeigt, dass das Bettpaneel von Ugarit ein hervorragendes Erzeugnis des lokalen Kunsthandwerks ist, gleichzeitig aber die kontinuierliche Übernahme fremder Motive bezeugt.rnWelche Vorbilder haben diese Rezeption begünstigt? Handelte es sich dabei um bewusste Anpassung an heimische Vorstellungen oder vielmehr um getreue Wiedergabe? Warum ließen sich die ugaritischen Handwerker von fremden Kunsttraditionen inspirieren? rnDank der detaillierten Untersuchung des Bettpaneels von Ugarit lassen sich diese wesentlichen Fragen über die Mechanismen der sozialen und kulturellen Interaktionen zwischen den Zivilisationen des Ostmittelmeergebiets im 2 Jt.s v. Chr. endgültig antworten.

[House dust mite allergy]

House dust mites can be found all over the world where human beings live independent from the climate. Proteins from the gastrointestinal tract- almost all known as enzymes - are the allergens which induce chronic allergic diseases. The inhalation of small amounts of allergens on a regular base all night leads to a slow beginning of the disease with chronically stuffed nose and an exercise induced asthma which later on persists. House dust mites grow well in a humid climate - this can be in well isolated dwellings or in the tropical climate - and nourish from human skin dander. Scales are found in mattresses, upholstered furniture and carpets. The clinical picture with slowly aggravating complaints leads quite often to a delayed diagnosis, which is accidently done on the occasion of a wider spectrum of allergy skin testing. The beginning of a medical therapy with topical steroids as nasal spray or inhalation leads to a fast relief of the complaints. Although discussed in extensive controversies in the literature - at least in Switzerland with the cold winter and dry climate - the recommendation of house dust mite avoidance measures is given to patients with good clinical results. The frequent ventilation of the dwelling with cold air in winter time cause a lower indoor humidity. Covering encasings on mattresses, pillow, and duvets reduces the possibility of chronic contact with mite allergens as well as the weekly changing the bed linen. Another option of therapy is the specific immunotherapy with extracts of house dust mites showing good results in children and adults. Using recombinant allergens will show a better quality in diagnostic as well as in therapeutic specific immunotherapy.

The Man-Made Environment in Post-Stalinist Europe 1953-1968

This project looked at the various responses, both political and aesthetic, to the end of socialist realism and the return of pre-war modernism as a desirable ideal. It considered both the built environment and objects of daily use (furniture, radios, TV sets, etc.) in several countries of the region, including Estonia, Hungary, Poland, Russia and Romania, also comparing developments there with corresponding ones in the west. Among particular aspects considered were the effects of Kruschev's speech in December 1954 to workers in construction, machine-building and design industries, in which he argued against monumentalism and criticised both "classical architecture" and socialist realism. The team see the real issue in interpreting Eastern European architecture as its lack of a critical edge, since official discourses took the place of any form of criticism and architects sought to implement the "official line". Megastructures became increasingly popular from the 1960s onwards and in Romania, for instance, came to dominate the city in the late 1980s. Such structures proved an efficient way to control the environment in countries plagued by prefabrication and social housing, and the group see the exhibition of inflated concrete grids as perhaps the most important feature of Eastern European architecture in the 1960s and 1970s. They also point out the rarity of glass and steel architecture in the east, where the preferred material was concrete, a material seen as "revolutionary" as it was the product of heavy industry and was grey, i.e. the workers' colour. Tactile elements were more important here than the visual elements favoured in the west, and a solidity more in line with the dominant ideology than the ephemeral qualities of glass.

Colour Symbolism, Colour Preference in Hungarian Folklore and Folk Architecture"

The Hungarian way of decoration has certain characteristics which are rooted in the deep symbolism of ancient Hungarian mythical thinking. The ancient heritage of the Hungarians' former homeland somewhere in the Urals included eastern elements. During their migrations, the Hungarian tribes met other eastern peoples and their culture of decoration became mixed with elements drawn from these new contacts. These diverse influences mean that the Hungarian way of thinking, building and ornamentation show a certain dualism of Puritanism and rationalism in the creation of space and manufacturing, and rich fantasy in decoration and ornamentation. The Hungarians use coloured ornamentation to emphasise the symbolic importance of details. The colouring system of the built environment shows the same dualism: the main colour of the facades and inner walls is white, while the furniture, textiles, gates and windows, and sometimes the gable and fireplace are richly decorated. In Hungarian symbolism, the house and settlement are a model of the universe, so their different parts also have a transcendent meaning. The traditional meanings of the different colours reflect this transcendence. Each colour has ambivalent meanings: RED - the colour of blood - means violence and love. YELLOW - means sickness, death and ripeness (golden yellow). BLUE - means innocence, eternity (light blue) and old age, death (dark blue). BLACK - can be both ceremonial and mourning. WHILE - can have sacred meaning (bright white), while yellowish white fabric is the most common garb of both men and women in village society. GREEN - the only colour without a dual meaning, symbolises the beginning of life. Until the late 18th and early 19th centuries Hungarian folk art used one or two-coloured decoration (red, black, blue, red-blue or red-black), and from the early 19th century it moved to multi-coloured decoration. Colours are characteristically used in complementary contrast, with bright colours on a plain ground and an avoidance of subtle shadings.

Interactive Augmentation of Live Images using a HDR Stereo Camera

Adding virtual objects to real environments plays an important role in todays computer graphics: Typical examples are virtual furniture in a real room and virtual characters in real movies. For a believable appearance, consistent lighting of the virtual objects is required. We present an augmented reality system that displays virtual objects with consistent illumination and shadows in the image of a simple webcam. We use two high dynamic range video cameras with fisheye lenses permanently recording the environment illumination. A sampling algorithm selects a few bright parts in one of the wide angle images and the corresponding points in the second camera image. The 3D position can then be calculated using epipolar geometry. Finally, the selected point lights are used in a multi pass algorithm to draw the virtual object with shadows. To validate our approach, we compare the appearance and shadows of the synthetic objects with real objects.

Not for Designers: On the Inadequacies of EU Design Law and How to Fix It

Design rights represent an interesting example of how the EU legislature has successfully regulated an otherwise heterogeneous field of law. Yet this type of protection is not for all. The tools created by EU intervention have been drafted paying much more attention to the industry sector rather than to designers themselves. In particular, modern, digitally based, individual or small-sized, 3D printing, open designers and their needs are largely neglected by such legislation. There is obviously nothing wrong in drafting legal tools around the needs of an industrial sector with an important role in the EU economy, on the contrary, this is a legitimate and good decision of industrial policy. However, good legislation should be fair, balanced, and (technologically) neutral in order to offer suitable solutions to all the players in the market, and all the citizens in the society, without discriminating the smallest or the newest: the cost would be to stifle innovation. The use of printing machinery to manufacture physical objects created digitally thanks to computer programs such as Computer-Aided Design (CAD) software has been in place for quite a few years, and it is actually the standard in many industrial fields, from aeronautics to home furniture. The change in recent years that has the potential to be a paradigm-shifting factor is a combination between the opularization of such technologies (price, size, usability, quality) and the diffusion of a culture based on access to and reuse of knowledge. We will call this blend Open Design. It is probably still too early, however, to say whether 3D printing will be used in the future to refer to a major event in human history, or instead will be relegated to a lonely Wikipedia entry similarly to ³Betamax² (copyright scholars are familiar with it for other reasons). It is not too early, however, to develop a legal analysis that will hopefully contribute to clarifying the major issues found in current EU design law structure, why many modern open designers will probably find better protection in copyright, and whether they can successfully rely on open licenses to achieve their goals. With regard to the latter point, we will use Creative Commons (CC) licenses to test our hypothesis due to their unique characteristic to be modular, i.e. to have different license elements (clauses) that licensors can choose in order to adapt the license to their own needs.”

Larix decidua and other larches in Europe: distribution, habitat, usage and threats

The European larch (Larix decidua Mill.) is a pioneer, very long-lived, fast-growing coniferous tree, which occurs in the central and eastern mountains of Europe, forming open forests or pasture woods at the upper tree limits. Larch is the only deciduous conifer in Europe as an adaptation to continental alpine climates. In fact, it is able to tolerate very cold temperatures during winter and, by losing its needles, avoids foliage desiccation. It is a transitional species, colonising open terrain after natural disturbances. It forms pure stands but more often it is found with other alpine tree species, which tend to replace it if no other disturbances occur. Thanks to its adaptability and the durability of its wood, the European larch represents an important silvicultural tree species in the alpine regions, planted even outside its natural ranges. Its wood is largely used for carpentry, furniture and pulp for paper. In lower altitudes or with high precipitation rates, larch is more susceptible to fungal diseases. Outbreaks of insect defoliators, principally caused by the larch bud moth (Zeiraphera diniana), can limit tree development, with economic losses in plantations, but they rarely lead to the death of the trees.

Picea abies in Europe: distribution, habitat, usage and threats

Among the coniferous species, Norway spruce (Picea abies (L.) Karst.) is one of the most important trees in Europe both for economic and ecological aspects, with a long tradition of cultivation. It can be a big tree, reaching 50-60 m in height with a straight and regular trunk, particularly used for timber constructions, pulpwood for paper and furniture. This widespread species dominates the Boreal forests in Northern Europe and the subalpine areas of the Alps and Carpathian Mountains. Thanks to its high performances in different site conditions, it can also be found outside its natural distribution on lower elevations in more temperate forests. Norway spruce has been massively planted up to its niche limits, where it is particularly susceptible to heat and drought, due to its shallow root system. For this reason it is expected to be severely affected under global warming conditions. Disturbed and weakened plants can be easily attacked by rot fungi such as Heterobasidion annosum and Armillaria, or by the bark beetles Ips typographus, one of the most destructive spruce forest pests.

Diseño e innovación : una visión sobre la industria del mueble mendocino

Se analizaron los procesos de cambio tecnológico en la industria del mueble en Mendoza, considerando el rol del diseño industrial. Ésta partió del supuesto que el diseño, la innovación y la tecnología se vinculan en este proceso. Sin embargo, el diseño ocupa un papel de escasa relevancia. El objetivo fue analizar el proceso de cambio tecnológico, teniendo en cuenta la incidencia de la innovación y en particular del diseño; analizar las políticas públicas provinciales dirigidas hacia este subsector. Metodológicamente se combinaron los paradigmas cuantitativo y cualitativo. Se pudo caracterizar el subsector y los empresarios de las empresas. Se espera que con los resultados puedan verse beneficiados organismos públicos y privados e instituciones académicas (UNCuyo), especialmente los dedicados a la vinculación con el medio productivo.

Las confiscaciones y embargos de Rosas en Chascomús, 1840-1852

En este trabajo, a partir de la identificación de los propietarios afectados, se analiza el impacto local de las confiscaciones y embargos de Rosas. Se estimará la importancia de los muebles y útiles rematados y se considerará la magnitud del ganado bovino, ovino y equino extraído por los alcaldes locales para destinarlo a los ejércitos de frontera y de Santos Lugares. Además se indagará acerca de la época de los desembargos para comprobar si luego de los mismos los estancieros de Chascomús retomaron sus actividades y siguieron con la propiedad de sus estancias, tema éste directamente relacionado con un proyecto de más largo aliento que estudia la transmisión de la propiedad rural al noreste del río Salado y la constitución de un mercado de tierras entre fines del siglo XVIII y fines del XIX
