Modelo de mudança organizacional: estudo de caso no setor de compras

O presente trabalho apresenta um modelo de mudança organizacional para melhorar o processo empresarial de compra de uma construtora, proveniente do sistema de comunicação entre o escritório central e suas obras, a fim de identificar as oportunidades e deficiências existentes no sistema, seja de ordem tecnológica e/ou gerencial. O mapeamento das informações permite detectar os percursos desnecessários que impossibilitam o sistema de comunicação funcionar de forma ágil e otimizada, bem como perceber as oportunidades de melhorias contínuas ao processo. O método de pesquisa se baseou no aperfeiçoamento de processos empresariais, que consiste na modelagem do processo citado, por meio da coleta de dados, análise de documentos, desenho de fluxos de informações existentes no modelo e discussão dos resultados. Para validação da aplicação do método, fez-se o estudo de caso único em uma construtora do subsetor edificações, o qual gerou fluxogramas do processo de compras atual e proposto como modelo de mudança organizacional.

Drawing and surface: freehand architectural drawing mediated by digital

This paper discusses the redefinition of the function of freehand drawing in the design process in view of intuitive digital media. It sets forth an interpretive analysis of an experiment with drawing on opaque tablets, carried out with a group of students of the Instituto de Arquitetura e Urbanismo da Universidade de São Paulo. After a brief review of the current debate on freehand drawing and the advent of digital media, we examine the experiment as a possible way to elicit facts that may contribute to the discussion. To this end, our research has concentrated on the intuitive use enabled by existing digital media. It is our intention that this empirical approximation becomes a pilot experiment for the use of digital tablets in the process of construction the gaze of the student in Architecture and Urbanism as a reflection on the different cognitive dimensions that constitute the practice of drawing and its reinterpretation to develop new ideas.

O uso de modelos nos processos projetuais contemporâneos

Durante o processo de projeto, o arquiteto transpõe suas ideias para o campo real, do concreto. Os diversos modos de expressão e representação têm como função mediar essa interação, diminuindo a distância entre esses dois campos. Vive-se hoje, um momento de intensa transformação das estratégias projetuais, propiciada pelos novos meios digitais. Assim, esta pesquisa, centra-se na comparação entre diversos momentos do uso de modelos nos processos projetivos contemporâneos, através de uma investigação em escritórios de arquitetura paulistanos que utilizam o modelo físico como parte de seus processos de projeto. Busca-se entender qual o papel dessa ferramenta de representação e suas potencialidades nos dias atuais. Como estudo de caso, faz-se uma análise comparativa entre o uso das maquetes digital e física, destacando dois estudos: a maquete do Conjunto Ponte dos Remédios, do arquiteto Marcos Acayaba e as maquetes de estudos elaboradas pelo escritório Andrade Morettin Arquitetos, para o concurso para o Instituto Moreira Salles/SP. Entre os objetivos desse trabalho também se encontra uma análise da contribuição dos modelos físicos no Ensino de Arquitetura.

Model-Driven Methodology for Rapid Deployment of Smart Spaces based on Resource-Oriented Architectures

Advances in electronics nowadays facilitate the design of smart spaces based on physical mash-ups of sensor and actuator devices. At the same time, software paradigms such as Internet of Things (IoT) and Web of Things (WoT) are motivating the creation of technology to support the development and deployment of web-enabled embedded sensor and actuator devices with two major objectives: (i) to integrate sensing and actuating functionalities into everyday objects, and (ii) to easily allow a diversity of devices to plug into the Internet. Currently, developers who are applying this Internet-oriented approach need to have solid understanding about specific platforms and web technologies. In order to alleviate this development process, this research proposes a Resource-Oriented and Ontology-Driven Development (ROOD) methodology based on the Model Driven Architecture (MDA). This methodology aims at enabling the development of smart spaces through a set of modeling tools and semantic technologies that support the definition of the smart space and the automatic generation of code at hardware level. ROOD feasibility is demonstrated by building an adaptive health monitoring service for a Smart Gym.

Prototipos experimentales modernos: la colonia de Schorlemerallee y las villas Am Rupenhorn de los Luckhardt y Anker. Berlín 1924-1930

La colonia experimental de Schorlemerallee y las villas Am Rupenhorn son dos proyectos concluidos en 1930 por los hermanos Wassili y Hans Luckhardt con Alfons Anker en Berlín. Ambos proyectos forman parte del mismo proceso, que comienza en la Colonia -una exploración sobre el lenguaje moderno en una serie de fases sucesivas- y culmina con las Villas. Éstas últimas, realizadas inmediatamente después de la Colonia, son la síntesis de esa experiencia, aunque finalmente acabaron trascendiéndola, ya que se convirtieron en un modelo sobre la casa en la naturaleza, sobre la idea de la villa clásica y sobre los nuevos modos de habitar, alcanzando con el tiempo la condición de canon moderno. A pesar de ello, no es esta condición lo más importante. Lo singular en este caso, es el propio proceso de proyecto –Colonia versus Villas- un verdadero experimento en su concepción, método y resultados, a través del cual sus autores investigan nuevas tecnologías aplicadas a nuevas formas de habitar y desarrollan un nuevo lenguaje, cuyo resultado son unos prototipos tecnológicos, con los que pretenden, como diría Mies van der Rohe: “Me he esforzado por construir una arquitectura para una sociedad tecnológica. He intentado que todo resultara razonable y claro.....para que cualquiera pueda hacer arquitectura.” El momento y lugar no pueden ser más propicios: Berlín entre 1924 y 1930, en el mismo origen del Movimiento Moderno. El experimento se plantea con auténtico rigor científico. Los arquitectos diseñan, construyen y financian su proyecto, controlando todas sus variables. Especialmente, por lo insólito, es el control de la variable económica. Porque este factor, la economía, es para ellos una clave fundamental del proceso. Se trataba de demostrar que la Nueva Arquitectura (o Neues Bauen, como les gustaba denominarla) era capaz de construir mejor y más rápido la vivienda para una nueva sociedad. La revolución y la vanguardia van de la mano: son el Zeitgeist o espíritu de la época, un contexto que es parte sustancial del proceso, y como lo calificarían los Smithson, un contexto heroico. El concepto se centra en la tríada Bauhaus: diseño + tecnología x economía. En cuanto al método, se fijan una serie de parámetros –las variables del experimento- que se agrupan en tres categorías distintas: topología, tipología y tecnología. La combinación de las variables de cada categoría dará lugar a un sistema con unas características determinadas: una definición del espacio, una forma, un lenguaje y una tecnología, características que permiten establecer las reglas para su desarrollo. Los sistemas resultantes son tres, denominados según su doble condición tipológica/ tecnológica: 1. Sistema de muro de carga: Viviendas adosadas en zig-zag o Mauerwerksbauten. 2. Sistema de esqueleto de acero: Viviendas aisladas o Stahlskelettbauten 3. Sistema de hormigón armado: Viviendas en hilera recta o Betonbauten Las villas Am Rupenhorn se plantean a continuación como verificación de este proceso: la síntesis de las categorías desarrolladas en la Colonia. Pero llegan en un momento de gracia, justo cuando los Luckhardt y Anker se encuentran profundamente implicados en el proceso de desarrollo de un nuevo lenguaje y con la reciente experiencia de la Colonia, que ha sido un éxito en casi todos los aspectos posibles. “En 1930, están en la cumbre”, como diría su mejor crítico y antiguo colaborador: Achim Wendschuh. En las Villas, los arquitectos integran su lenguaje, ya plenamente moderno, con sus experiencias previas: las que los relacionan con su reciente expresionismo (que se podría calificar como Kunstwollen) y con la tradición clásica de la cultura arquitectónica alemana: el sentido del material que deben a Semper y la sensibilidad hacia el paisaje, que toman de Schinkel. El extraordinario interés de las Villas se debe a factores como el tratamiento de la relación dual, poco habitual en la arquitectura moderna, la síntesis de lenguajes y las circunstancias de su momento histórico, factores que las han convertido en una propuesta única e irrepetible de una de las vías experimentales más interesantes y desconocidas de la Modernidad. ABSTRACT The experimental Housing Estate of Schorlemerallee and the Am Rupenhorn Villas are two projects completed by the brothers Wassili and Hans Luckhardt with Alfons Anker in Berlin in 1930. Both projects are part of the same process, starting with the Housing Estate --an exploration of the modern language in a series of phases- which culminates with the Villas project. The Villas Am Ruperhorn, designed immediately after the Housing development, are the synthesis and crowning point of this experience, even finally over passing it, since they have become a model of the house in nature, related with both the ideal of the classical villa and the new ways of life, reaching the condition of a modern canon. However, this is not its most important issue. The most remarkable condition is the project process itself -Housing versus Villas- a true experiment in concept, method and results, in which the authors research new technologies for new ways of living, developing an innovative language, with results in new prototypes, in the way Mies van der Rohe was looking for: “I have tried to make an architecture for a technological society. I have wanted to keep everything reasonable and clear… to have an architecture that anybody can do." The time and place could not be more favourable: Berlin from 1924 to 1930, in the very origin of Modern Movement. The experiment takes place with genuine scientific accuracy. Architects design, build and finance their own project, controlling all variables. Especially, and quite unusual, the control of the economic variable. Precisely the economic factor is for them a fundamental key to the process. It was shown to prove that the new architecture (or Neues Bauen, as they liked to call it) was able to build not only faster, better and more efficient dwellings for a new society, but also at lower cost. Revolution and Avant-garde use to move forward together, because they share the Zeitgeist --or time's spirit--, a context which is a substantial part of the process, and as the Alison & Peter Smithsons would describe, an heroic context. The concept focuses on the Bauhaus triad: Design + Technology x Economy. For the method, a number of variables are fixed --the experimental parameters-- that are later grouped into three distinct categories: Topology, Typology and Technology. The combination of these variables within each category gives way to several systems, with specific characteristics: a definition of space, a form, a language and a technology, thus allowing to establish the rules for its development: The resulting systems are three, called by double typological / technological issue: 1. Terraced Housing in zig-zag or Mauerwerksbauten (bearing wall system) 2. Detached Housing or Stahlskelettbauten (steel skeleton system) 3. Terraced Housing in one row or Betonbauten (reinforced concrete system) The Am Rupenhorn Villas are planned as the check of this process: the synthesis of the categories developed all through the Housing Estate research. The Am Ruperhorn project is developed in a crucial moment, just as the Luckhardts and Anker are deeply involved in the definition process of a new language after the recent experience of Schorlemerallee, which has been a success in almost all possible aspects. "In 1930, they are on the top” has said his best critic and long-time collaborator, Achim Wendschuh. In the Villas, the authors make up their fully modern language with their own background, related with their recent Expressionist trend (Kunstwollen) and with the classical tradition of the German architectural culture: the notion of material related with Semper and the sensible approach to the landscape, linked with Schinkel. Its extraordinary interest lay on diverse factors, such as dual relationships, unusual in modern architecture, synthesis of languages and circumstances of their historical moment, all factors that have become a unique and unrepeatable proposal in one of the most extraordinary experimental ways of Modernity.

Can Lis : la huella de la arquitectura de Jørn Utzon a través de esta obra

La tesis “CAN LIS, La huella de la arquitectura de Jørn Utzon a través de su obra Can Lis” analiza en profundidad la vivienda que Jørn Utzon realizó para sí mismo en la entonces calle de la Media Luna, Porto Petro, Mallorca, entre los años 1970-74. La investigación plantea el análisis de esta obra maestra de la arquitectura, sus causas e intenciones, su proceso proyectual, su proceso constructivo, sus relaciones e influencias y sus significados últimos. Este estudio es fruto de una labor de investigación que comenzó hace más de 10 años. Enfrentarse a una obra cuya imagen es tan conocida es una tarea menos sencilla de lo que pudiera parecer. La descripción del proceso de trabajo de Jørn Utzon en Can Lis, y de su método en general, contiene un considerable número de mitificaciones que han sido comúnmente sostenidas por diversos estudiosos de prestigio, que han abordado esta obra sin un estudio razonable de la documentación existente, ni una investigación de los archivos, ni una comprobación de los hechos o una consulta de los testigos intervinientes. Por ello, cuestiones fundamentales habían quedado en el terreno de la conjetura y permanecía deformada la visión general de los procesos de Jørn Utzon en Mallorca. La tesis se ha estructurado en dos grandes apartados que permitan la comprensión de los elementos fundamentales para su gestación: por un lado, el proceso proyectual y constructivo con sus circunstancias y condicionantes y, por otro, el conjunto de hechos y conceptos que han influido de manera directa y significativa en su concreción. Esta investigación contiene una cantidad considerable de materiales y hechos inéditos, fruto de su desarrollo, así como documentación y dibujos nunca publicados anteriormente. Es por tanto, el estudio más completo realizado sobre Can Lis hasta la fecha. En la primera parte de la tesis “CAN LIS” se aborda todo el proceso proyectual de Can Lis desde los primeros croquis, con las condiciones y motivaciones iniciales, los proyectos sucesivos, el proyecto básico y el proyecto de ejecución, hasta el proceso de construcción, su desarrollo y circunstancias, así como las modificaciones posteriores introducidas. Estos elementos se estructuran en tres apartados 1) Las condiciones y condicionantes iniciales. 2) El proceso proyectual. 3) El proceso constructivo. En la segunda parte de la tesis “La huella de la arquitectura de Jørn Utzon a través de su obra Can Lis” se han analizado de manera particular algunos hechos arquitectónicos y vitales previos que fueron especialmente determinantes en la concepción de Can Lis y la serie de influencias directas que son imprescindibles para la comprensión de las condiciones en que se desarrolló y de las ideas que alumbra. Estudios previos de toda la trayectoria de Utzon y todo el corpus de influencias ayudaron a determinar cuáles de ellos son fundamentales para la comprensión del proceso. Estos elementos se pueden considerar directamente precursores de ideas desarrolladas específicamente en Can Lis: 4) La experimentación en Australia: la naturaleza, la dimensión humana y la técnica. La casa de Bayview. 5) Utzon y el descubrimiento de lo islámico: la secuencia espacial, la materia y la luz de la arquitectura islámica como experiencia de aprendizaje. 6) Paisaje sacro, hombre y arquitectura: la búsqueda de Utzon en Grecia. Las conclusiones de este estudio determinan una serie de certezas sobre los procesos de Jørn Utzon en Can Lis, y en su obra global, durante las diversas fases creativas que desmitifican muchos acercamientos precedentes: la visión universal de la arquitectura en su acercamiento al proyecto, el entretejido método proyectual de Utzon, la precisa búsqueda del desarrollo constructivo junto a la ejemplaridad en el rigor, la vitalidad y la espiritualidad con que Utzon aborda la arquitectura, la trascendencia de la forma de habitar de las personas y el valor que para Utzon tiene la arquitectura como medio para revelar el orden universal que nos rodea. ABSTRACT “CAN LIS. The footprint of Jørn Utzon´s architecture through his work Can Lis” carries out a thorough analysis of the house Jørn built for himself between 1970 and 1974 on the street formerly called Calle de la Media Luna, in Porto Petro on the island of Mallorca. The research focuses on the causes that brought about this masterpiece, its purposes, design and building processes, its relations with and influences on other buildings and its ultimate meanings. This study is the result of a research that started over 10 years ago. Approaching a piece of work whose image is so well-known is harder than one might think. Many aspects of Jørn Utzon´s working method in Can Lis particularly but also generally have been described inaccurately and mythicized by several renowned scholars, who hadn´t really studied the existing documents or archives nor confirmed their hypotheses or consulted witnesses of the creation of Can Lis. This is why many key issues have been uncertain all this time and the general idea about Utzon´s working process in Mallorca has been distorted. This dissertation has been structured into two main sections with the aim of helping understand all the facts that led to the creation of the building: the first part describes the design and building processes, as well as the circumstances and constraints under which they were carried out. The second part presents the events and ideas that directly and indirectly influenced the final work. This thesis contains a large amount of unpublished material and information, documents and drawings from the creation process as the inevitable result of a long lasting tenacious research. It probably is the most comprehensive study on Can Lis so far. The first section, “CAN LIS”, addresses the design process of Can Lis from the very first sketches all the way through the subsequent plans, including basic and execution plans and the building process up to the changes that were later carried out on the building. The project´s initial conditions and Utzon´s first motivations and the evolution and circumstances of the building process are also described in this section, which has been divided into three parts: 1. The initial conditions and constraints. 2. The design process. 3. The building process. The second section, “The footprint of Jørn Utzon´s architecture through his work Can Lis”, focuses on some events in Utzon´s life and some of his architectural experiences prior to the creation of Can Lis that were decisive to it. Also the direct influences on the process which are key to understanding the conditions under which the creation was carried out as well as the ideas Can Lis sheds a light on are illustrated in this section. A thorough study of the whole process Utzon went through and of all the influences he was subjected to helped determine what is crucial to comprehending Can Lis. These events or experiences can be considered as the direct precursors to the ideas that crystallised in this master piece: 4. Experiments carried out in Australia: nature, human and technical dimensions. The Bayview house. 5. Utzon´s discovery of Islamic architecture: spatial sequences, matter and light as a learning experience. 6. Sacred landscape, man and architecture: Utzon´s quest in Greece. The findings of this research determine some aspects of Utzon´s working methods at every stage of the creation process both in Can Lis and in general, thus shedding light on previous mistaken ideas about Utzon´s way of working. A universal understanding of architecture, an intertwined design method, a tenacious search for the exact construction solutions, an exemplary rigour, vitality and spirituality in the design approach, the transcendence of our way of living and architecture´s potential to reveal the Universal order that surrounds are all aspects that do define Utzon as an architect.

NATO’s presence in the Baltic states – reassurance of allies or deterrence for Russia? OSW COMMENTARY Number 169, 29.04.2015 2015-04-29

In late March and early April, the US Air Forces in Europe (USAFE) held an exercise in Estonia, during which US F-16s destroyed ground targets in an Estonian firing range. Around the same time the Americans held a drill with the Swedish and Finnish Air Forces over the Baltic Sea. The United States has been playing a leading role in the process of strengthening NATO’s presence in the Baltic states. As far as the Western European allies are concerned, Germany will follow in the footsteps of Denmark and the United Kingdom, both of which made significant military contributions to the strengthening of the allied presence in 2014, and will deploy the largest number of troops in 2015. Non-aligned Sweden and Finland, key for the performance of NATO operations in the Baltic states, have been emphasising their military and political readiness to co-operate with NATO in the event of potential crises or conflicts. Comparing NATO ‘s military presence in the Baltic states before and after the outbreak of the Russian intervention in Ukraine, it is clear that NATO has stepped up its engagement considerably. However, its scope is still relatively small, given the much larger military potential and mobilisation capacity of Russia. Moreover, the message sent by NATO’s actions may be diminished by the political, military and financial constraints faced by the allies and Sweden and Finland. It seems that the greatest risk to the military security of the Baltic states currently appears to be the possibility that Russia could wrongly assess the reliability of NATO’s security guarantees.

Relating Innovative 2D Ideas into 3D Garments in Terms of Structure, Using ‘Sculptural Form Giving’ as an Intermediate Step in Creation.

This research focuses on finding a fashion design methodology to reliably translate innovative two-dimensional ideas on paper, via a structural design sculpture, into an intermediate model. The author, both as a fashion designer and a researcher, has witnessed the issues which arise, regarding the loss of some of the initial ideas and distortion during the two-dimensional creative sketch to three-dimensional garment transfer process. Therefore, this research is concerned with fashion designers engaged in transferring a two-dimensional sketch through the method ‘sculptural form giving’. This research method applies the ideal model of conceptual sculpture, in the fashion design process, akin to those used in the disciplines of architecture. These parallel design disciplines share similar processes for realizing design ideas. Moreover, this research investigates and formalizes the processes that utilize the measurable space between the garment and the body, to help transfer garment variation and scale. In summation, this research proposition focuses on helping fashion designers to produce a creative method that helps the designer transfer their imaginative concept through intermediate modeling.

Architecture for IoT Node and Platform

Only recently, during the past five years, consumer electronics has been evolving rapidly. Many products have started to include “smart home” capabilities, enabling communication and interoperability of various smart devices. Even more devices and sensors can be remote controlled and monitored through cloud services. While the smart home systems have become very affordable to average consumer compared to the early solutions decades ago, there are still many issues and things that need to be fixed or improved upon: energy efficiency, connectivity with other devices and applications, security and privacy concerns, reliability, and response time. This paper focuses on designing Internet of Things (IoT) node and platform architectures that take these issues into account, notes other currently used solutions, and selects technologies in order to provide better solution. The node architecture aims for energy efficiency and modularity, while the platform architecture goals are in scalability, portability, maintainability, performance, and modularity. Moreover, the platform architecture attempts to improve user experience by providing higher reliability and lower response time compared to the alternative platforms. The architectures were developed iteratively using a development process involving research, planning, design, implementation, testing, and analysis. Additionally, they were documented using Kruchten’s 4+1 view model, which is used to describe the use cases and different views of the architectures. The node architecture consisted of energy efficient hardware, FC3180 microprocessor and CC2520 RF transceiver, modular operating system, Contiki, and a communication protocol, AllJoyn, used for providing better interoperability with other IoT devices and applications. The platform architecture provided reliable low response time control, monitoring, and initial setup capabilities by utilizing web technologies on various devices such as smart phones, tablets, and computers. Furthermore, an optional cloud service was provided in order to control devices and monitor sensors remotely by utilizing scalable high performance technologies in the backend enabling low response time and high reliability.

Sistema de realidade aumentada no procedimento cirúrgico de remoção de pedras nos rins

A inovação tecnológica e as facilidades que gera tem tido um impacto crescente em diversas área, inclusivamente na medicina. A rápida evolução por parte de algumas tecnologias, como é o caso da Realidade Aumentada (RA), criam excelentes oportunidades, nomeadamente para intervenções cirúrgicas laparoscópicas, que apresentam especialmente problemas ao nível da exposição do doente a radiação. O presente documento detalha todo o processo de investigação e desenvolvimento realizado com a pretensão de criar um sistema de navegação por RA que auxilie o procedimento cirúrgico laparoscópico de remoção de pedras nos rins. Com este objetivo em perspetiva, e numa parceria com a empresa ECmedica LTD, foram desenvolvidos quatro protótipo funcionais. Com o intuito de compreender as melhores práticas de sistemas de input, interface e sistema de registo a aplicar, estes integraram aspetos inovadores tais como a utilização de uma sonda ultra-som, como substituta do raioX, e um registo feito através de sensores magnéticos. Apoiados numa metodologia de design centrado no utilizador e em instrumentos de análise como entrevistas e observação natural, os protótipos foram testados, obtendo respostas esclarecedoras relativamente ao objetivos dos protótipos. Foi observado que a RA é vista pelos médicos como uma solução com potencial, com as soluções apresentadas ao nível de inputs, interface e registo a serem bem recebidas. A projeção bidimensional oferecida pela imagem ultra-som foi encarada como insuficientes, sendo sugerida a sua substituição por um aumento tridimensional capaz de facilitar a correta inserção da agulha.

Constraints to the efficacy of risk management process in entrepreneurial companies

This paper highlights potential factors that affect the degree of efficacy of a formal risk management framework in entrepreneurial organisations. The understanding of entrepreneur’s self-schemas, entrepreneurial organisational culture and working environment is crucial to evaluate the efficacy of a risk management process. This research pointed out two main issues: i) the entrepreneurial decision making process with presence of biases and heuristics in judgement under uncertainty; and ii) the entrepreneurial organisational context that might create constraints to the implementation of a risk management framework.

Drivers of technology substitution : successive generations of high tech products

Principal Topic High technology consumer products such as notebooks, digital cameras and DVD players are not introduced into a vacuum. Consumer experience with related earlier generation technologies, such as PCs, film cameras and VCRs, and the installed base of these products strongly impacts the market diffusion of the new generation products. Yet technology substitution has received only sparse attention in the diffusion of innovation literature. Research for consumer durables has been dominated by studies of (first purchase) adoption (c.f. Bass 1969) which do not explicitly consider the presence of an existing product/technology. More recently, considerable attention has also been given to replacement purchases (c.f. Kamakura and Balasubramanian 1987). Only a handful of papers explicitly deal with the diffusion of technology/product substitutes (e.g. Norton and Bass, 1987: Bass and Bass, 2004). They propose diffusion-type aggregate-level sales models that are used to forecast the overall sales for successive generations. Lacking household data, these aggregate models are unable to give insights into the decisions by individual households - whether to adopt generation II, and if so, when and why. This paper makes two contributions. It is the first large-scale empirical study that collects household data for successive generations of technologies in an effort to understand the drivers of adoption. Second, in comparision to traditional analysis that evaluates technology substitution as an ''adoption of innovation'' type process, we propose that from a consumer's perspective, technology substitution combines elements of both adoption (adopting the new generation technology) and replacement (replacing the generation I product with generation II). Based on this proposition, we develop and test a number of hypotheses. Methodology/Key Propositions In some cases, successive generations are clear ''substitutes'' for the earlier generation, in that they have almost identical functionality. For example, successive generations of PCs Pentium I to II to III or flat screen TV substituting for colour TV. More commonly, however, the new technology (generation II) is a ''partial substitute'' for existing technology (generation I). For example, digital cameras substitute for film-based cameras in the sense that they perform the same core function of taking photographs. They have some additional attributes of easier copying and sharing of images. However, the attribute of image quality is inferior. In cases of partial substitution, some consumers will purchase generation II products as substitutes for their generation I product, while other consumers will purchase generation II products as additional products to be used as well as their generation I product. We propose that substitute generation II purchases combine elements of both adoption and replacement, but additional generation II purchases are solely adoption-driven process. Extensive research on innovation adoption has consistently shown consumer innovativeness is the most important consumer characteristic that drives adoption timing (Goldsmith et al. 1995; Gielens and Steenkamp 2007). Hence, we expect consumer innovativeness also to influence both additional and substitute generation II purchases. Hypothesis 1a) More innovative households will make additional generation II purchases earlier. 1 b) More innovative households will make substitute generation II purchases earlier. 1 c) Consumer innovativeness will have a stronger impact on additional generation II purchases than on substitute generation II purchases. As outlined above, substitute generation II purchases act, in part like a replacement purchase for the generation I product. Prior research (Bayus 1991; Grewal et al 2004) identified product age as the most dominant factor influencing replacements. Hence, we hypothesise that: Hypothesis 2: Households with older generation I products will make substitute generation II purchases earlier. Our survey of 8,077 households investigates their adoption of two new generation products: notebooks as a technology change to PCs, and DVD players as a technology shift from VCRs. We employ Cox hazard modelling to study factors influencing the timing of a household's adoption of generation II products. We determine whether this is an additional or substitute purchase by asking whether the generation I product is still used. A separate hazard model is conducted for additional and substitute purchases. Consumer Innovativeness is measured as domain innovativeness adapted from the scales of Goldsmith and Hofacker (1991) and Flynn et al. (1996). The age of the generation I product is calculated based on the most recent household purchase of that product. Control variables include age, size and income of household, and age and education of primary decision-maker. Results and Implications Our preliminary results confirm both our hypotheses. Consumer innovativeness has a strong influence on both additional purchases (exp = 1.11) and substitute purchases (exp = 1.09). Exp is interpreted as the increased probability of purchase for an increase of 1.0 on a 7-point innovativeness scale. Also consistent with our hypotheses, the age of the generation I product has a dramatic influence for substitute purchases of VCR/DVD (exp = 2.92) and a strong influence for PCs/notebooks (exp = 1.30). Exp is interpreted as the increased probability of purchase for an increase of 10 years in the age of the generation I product. Yet, also as hypothesised, there was no influence on additional purchases. The results lead to two key implications. First, there is a clear distinction between additional and substitute purchases of generation II products, each with different drivers. Treating these as a single process will mask the true drivers of adoption. For substitute purchases, product age is a key driver. Hence, implications for marketers of high technology products can utilise data on generation I product age (e.g. from warranty or loyalty programs) to target customers who are more likely to make a purchase.

Detailed landscape plan for the North section of the Bailang River north of Jiqing Highway, Weifang

International practice-led design research in landscape architecture has identified wetland sites as highly significant and potentially fragile environments in many countries. China has considerable wetland acreage that has been drained and transformed into farmland to address local poverty of farmers. An important gap in knowledge exists as to how to design Chinese public open spaces to reduce water contamination, flood severity and loss of farmland for local villagers as urban development expands. This project responded to the opportunity of introducing a new type of wetland design to Stage 3 of the Bailang River Redevelopment, Weifang City, Shandong Province. The work proposed a range of wetland design innovations for Chinese wetland environments to encourage on-site solutions to contamination and flooding problems.

On location : the imagined private interior in public life

This paper reveals the interior landscapes of selected contemporary Australian films, such as The Caterpillar Wish and Bad Boy Bubby, to develop a number of thematic influences on the manner in which domestic and private lives are constructed through filmic imagination. The research uncovers the conditions that contribute to particular scenographic representations of the humble interiors that act as both backdrop and performer to subtle and often troubled narratives. Such readings are informed by the theoretical works of writer Gertrude Stein, among others, who explore the relationships between the scenographic third dimension and the fourth dimensional performance in the representation of narrative space. A further theoretical thread lies in Giuliana Bruno’s work on the tension between private and public filmic space, which is explored through the public outing of intensely private spaces generated through narratives framed by the specificities of found interiors. Beyond the interrogation of qualities of imagined filmic space is the condition whereby locations, once transformed by the event of movie making are consequently forever revised. These altered conditions subsequently reinvest the lives of those who return to the location with layered narratives of occupation. Situationally, the now reconverted interior performs as contributor to subsequent private inhabitation, even if only as imagined space. The possibility here is that the qualities of the original may be superimposed and recontextualised to invest post-produced interiors with the qualities of the other space as imagined. This reading of film space explores new theoretical design scenarios for imagined and everyday interior landscapes.
