ISBN: 978 88 6493 027 5; The proposal methodology tends to close the “product fashion cycle”, defending the existence of a good waste management policy, so that the clothing are thrown away can be reused or recycled to come back again as material to produce yarn, fabric or knit. Subsequently these materials should be include in the production of sustainable apparel, whose design methodologies should be concerned in providing more durable garments and being possible to transform according to the occasion and the user. With that manner, the Fashion Design Process will be different in all stages of working and according with all stages of the fashion product lifespan. We will present a model with many methodologies to solve different types of problems that will be considered across the Lifecycle in Fashion Clothing.

Objectives: To investigate the safety and efficacy of durable polymer drug eluting stents (DES) and biodegradable polymer biolimus eluting stents (biolimus-ES). Design: Network meta-analysis of randomised controlled trials. Data sources and study selection Medline, Google Scholar, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL) database search for randomised controlled trials comparing at least two of durable polymer sirolimus eluting stents (sirolimus-ES) and paclitaxel eluting stents (paclitaxel-ES), newer durable polymer everolimus eluting stents (everolimus-ES), Endeavor and Resolute zotarolimus eluting stents (zotarolimus-ES), and biodegradable polymer biolimus-ES. Primary outcomes Safety (death, myocardial infarction, definite or probable stent thrombosis) and efficacy (target lesion and target vessel revascularisation) assessed at up to one year and beyond. Results: 60 randomised controlled trials were compared involving 63 242 patients with stable coronary artery disease or acute coronary syndrome treated with a DES. At one year, there were no differences in mortality among devices. Resolute and Endeavor zotarolimus-ES, everolimus-ES, and sirolimus-ES, but not biodegradable polymer biolimus-ES, were associated with significantly reduced odds of myocardial infarction (by 29-34%) compared with paclitaxel-ES. Compared with everolimus-ES...

Aujourd’hui, nous savons qu’environ 75 à 80% des impacts environnementaux des produits sont déterminés lors de la conception. Le rôle du designer industriel est donc crucial pour arriver à une forme de développement plus viable. Cette recherche tente de cibler les champs de connaissances qui devraient faire partie de la formation des professionnels du développement de produits pour y intégrer les aspects environnementaux. Après une recension de la littérature en design industriel, en pédagogie et en environnement, l’étude de terrain a été conduite en deux temps. Selon des critères prédéfinis, des programmes universitaires « spécialisés » en environnement/développement durable, au Québec, ainsi que des formations en éco-conception, offerts en France, ont été analysés. L’étude de terrain a été complétée par un entretien en profondeur semi-dirigé avec un consultant, qui aide des entreprises québécoises à intégrer l’environnement en développement de produits. L’analyse des informations recueillies met en évidence la nécessité de transformer rapidement les formations universitaires en conception de produits. Le nouveau cursus de design industriel devrait; 1. Intégrer les connaissances relatives aux impacts environnementaux; 2. Encourager le travail en équipes multidisciplinaires pour enrichir la collecte d’informations relative aux projets de développement; 3. Établir une collaboration étroite entre les établissements d’enseignement et les industries...

Dans les sphères du développement durable, des modèles d’affaires et du design de produit, certains leviers rendent le croisement de ces trois sphères de plus en plus pertinent. Au croisement de ces trois sphères se trouve une opportunité de comprendre les relations existantes entre le design de produit et les modèles d’affaires afin d’aider les décideurs à développer des solutions davantage durables. L’approche méthodologique de cette recherche utilise un système complexe et est basée sur un paradigme pragmatique. En vue de répondre à la question « Dans quelle mesure des modèles d’affaires et le design de produit sont liés dans un contexte de développement durable? », cette recherche a soigneusement analysé trois cas: Better Place, une compagnie californienne ayant développé une infrastructure permettant le chargement des voitures électriques; Interface Inc., un manufacturier mondial de tuiles de tapis commerciales établi à Atlanta; et Métacycle, un concept d’entreprise développé par une équipe de chercheurs en design à Montréal. Chaque cas a été analysé en corrélant des aspects du design de produit à des éléments de leur modèle d’affaires. Les résultats montrent que dans le contexte du développement durable...

Depuis quelques temps, on note que les objets d’apparence artisanale symbolisent souvent des qualités écologiques telles que des matériaux naturels et une fabrication éthique. Les visées de l’étude ont été d’explorer les perceptions à l’égard des objets à caractère artisanal et cela, en vue de reconnaître quelles qualités écologiques sont attribuées à ces derniers, tout en tentant de comprendre les raisons qui se cachent derrière ces associations. Une étude auprès d’usagers a permis d’explorer l’ensemble des qualités pouvant être liées à ce type d’objet, en considérant plus précisément le rapport entre les qualités écologiques leur étant accordées et leur durée de vie projetée. Pour ce faire, au cours d’entretiens individuels, des thèmes comme l’appréciation à long terme, la signification et la considération de la diversité culturelle ont été examinés. Les résultats montrent entre autres que les objets à caractère artisanal sont caractérisés comme étant composés de matériaux naturels et sains pour la santé des usagers. Leur usure est reconnue comme éveillant les représentations quant à leur « histoire », alors que leur originalité leur confère une « âme ». Enfin...

Why do many households remain exposed to large exogenous sources of non-systematic income risk? This paper uses a series of randomized field experiments in rural India to test the importance of price and non-price factors in the adoption of an innovative rainfall insurance product. The analysis finds that demand is significantly price-elastic, but that even if insurance were offered with payout ratios similar to US, widespread coverage would not be achieved. The paper identifies key non-price frictions that limit demand: liquidity constraints, particularly among poor households, lack of trust, and limited salience. The authors suggest potential improvements in contract design to mitigate these frictions.

Measuring poverty and tracking it over time is an important prerequisite to national economic planning. Absence of official data on household expenditure or poverty line hampered the ability of Iraqi policymakers to understand the extent of the problem, analyze their causes, and devise appropriate policies. Iraq household socioeconomic survey (IHSES) 2006-07 was the first survey of its kind since 1988 to cover all 18 governorates. The survey collected rich information on income, expenditure, employment, housing, education, health, and other socioeconomic indicators. Building on the experience of the first IHSES survey and using international best practice on sampling and questionnaire design and survey implementation, the second round of IHSES was fielded in 201-/13. To fill the data gap, a larger survey was designed to collect information on correlates of household welfare like demographic characteristics, education, occupation, housing, and assets and estimate small-area poverty rates using projection methods. This report presents results from the exercise...

Importance of consideration of chloride induced corrosion in service life design of reinforced concrete (RC) structures situated in marine environment is well known. This paper attempts to provide, within the framework of Monte Carlo Simulation, methodologies for durability based service life design of RC members. A methodology using fragility curves is proposed to assist in the service life design of freely degrading RC flexural beams. For maintained RC beams, a methodology is developed, that incorporates the concepts of virtual aging, failure rate approach and time-variant reliability analysis. By addressing maintenance at the design stage itself, the methodology developed would help in sustainability based service life design. The use of both the methodologies is demonstrated by considering an example of T-beam. From the results of the example problem considered, it has been found that corrosion initiation time would govern the service life. 30% replacement of cement with pulverized fuel ash is considered as a sustainable alternative for construction of durable structures satisfying the service life performance targets with lesser number of repairs.

Thesis (Ph.D.) - Indiana University, Folklore and Ethnomusicology, 2013; Limited Pre-Modern calculating skills favored geometry for design and layout. Technical limitations precluding durable, detailed measured drawings favored sequentially proportional steps transmitting information from design to construction. The Ancient Egyptian phrase "Casting the plan-net on the ground" implies a rectilinear network of geometrical lines serving to locate plan elements on the ground. Reconstruction of Polykleitos' Kanon demonstrates design parameters based on sequential proportionality that extracts a "correctly" proportioned human figure from an original square base figure. Fifteenth century booklets describe extraction of a completed architectural form from the base figure. Iconographic sources trace these Ancient World methods from their use in practical implementation to symbolization as eighteenth century remembrances in Free Mason paraphernalia. To associate floor plan elements with a rectilinear network, plan-net geometry manipulates proportional relationships of squares and rectangles in sequentially proportional steps. Geometrical design steps by divider and straightedge are identical to ground-lines steps by cord and peg...

This summary report is the culmination of a comprehensive, more than a year-long, collaboration between the World Bank, Fiji Department of Social Welfare (DSW), Fiji Islands Bureau of Statistics (FIBOS) and AusAID. It reflects various activities undertaken under the work program that was agreed upon with the Government of Fiji (GOF), with financial support provided by AusAID under the Externally Funded Output (EFO) agreement with the World Bank. The objective of this report is to present the key findings and issues that emerged from the analysis, as well as potential options for policy changes. The recommendations are made with a view of being very concrete, and also with understanding that while some of them could be implemented quickly, others should be considered for medium to long term. This summary report intentionally omits some technical details, since those are available in the accompanying background papers on various issues. The remainder of the report is structured as follows. Section two presents the profile of poverty and vulnerability in Fiji. It is intended to provide a context for the discussion of the social protection system. Section three presents a brief overview of the current social protection system in Fiji. Section four presents the key design features of Family Assistance Program (FAP) and discusses the program's strengths and challenges by looking at the range of the performance indicators. The discussion in this section reflects the findings emerging from the quantitative and qualitative analysis of the FAP. Section five considers some of the policy options for the design of the SP system moving forward. In a way...

Scientifiques, gouvernements, entreprises et consommateurs s’entendent aujourd’hui pour dire que le système naturel est déréglé, que l’activité industrielle en est la cause principale. L’éco-conception est une manière de concevoir des biens ou des services en diminuant leurs impacts sur l’environnement et la société. De plus en plus présente dans les grandes entreprises où, associée à une gestion intégrée de l’environnement, elle procure des bénéfices non négligeables et une image de marque, l’éco-conception a beaucoup de difficultés à s’implanter dans les petites et moyennes entreprises. Dans ce travail, nous avons cherché à comprendre les raisons de ces difficultés. Deux approches ont été utilisées, l’une basée sur une analyse documentaire des rapports de RSE de dix entreprises, grandes et petites, de différents secteurs d’activité, qui nous a permis de fixer le cadre et le formalisme de la démarche de recherche, l’autre sur le principe d’entretiens semi-dirigés à partir de questions ciblées. Après une présentation générale de ce qu’est l’éco-conception et quelle en est la problématique appliquée aux PME (chapitre 2), nous précisons le cadre méthodologique de la recherche (chapitre 3) et exposons ses résultats (chapitre 4). Nous montrons que les freins à l’adoption de l’éco-conception dans les PME sont multiples et complexes...

Ce document s’inscrit dans la foulée des préoccupations mondiales sur le devenir des villes au XXIe siècle. Il questionne les façons de faire qui contribuent à un développement de qualité des cadres de vie des citoyens. Les processus d’idéation de type atelier et charrette sont retenus en regard de leurs valeurs mobilisatrices et consensuelles qui répondent aux principes du développement durable. La problématique posée concerne l’adaptation de leur structure de fonctionnement au contexte local dans lequel il s’applique et de leur performance à induire les résultats escomptés. Une analyse comparative de trois études de cas révèle que le processus d’idéation se singularise en fonction des modalités de communication nécessaires pour progresser dans la démarche de planification des projets et conjointement à ceci, confirme que leur performance réside en leur capacité de rassembler l’ensemble des acteurs du projet en un même lieu. À l’issue de notre étude, nous fournissons un procédurier préliminaire pour diriger la mise en œuvre de processus d’idéation localement.; This paper rejoins worldwide concerns for the future of cities in the XXlth century. It questions the practices, which contribute to the development of environmental qualities in the living environment. The collective creative efforts deployed in charrettes and workshops are considered to be relevant to the mobilization and reconciliation of values; principles necessary for sustainable development. The specific problematic concerns the adaptation of different operating structures of charrettes from one local context to another in order to insure desired outcomes. A comparative analysis of three case studies reveals that the creative processes of charrettes are adapted to the modes of communication required to advance the project planning process and confirms that their performance relies on their capacity to gather consensus in the actors concerned. Finally we supply a preliminary toolkit to help the future implementation of the charrette’s creative processes locally.

Cette thèse contribue à une théorie générale de la conception du projet. S’inscrivant dans une demande marquée par les enjeux du développement durable, l’objectif principal de cette recherche est la contribution d’un modèle théorique de la conception permettant de mieux situer l’utilisation des outils et des normes d’évaluation de la durabilité d’un projet. Les principes fondamentaux de ces instruments normatifs sont analysés selon quatre dimensions : ontologique, méthodologique, épistémologique et téléologique. Les indicateurs de certains effets contre-productifs reliés, en particulier, à la mise en compte de ces normes confirment la nécessité d’une théorie du jugement qualitatif. Notre hypothèse principale prend appui sur le cadre conceptuel offert par la notion de « principe de précaution » dont les premières formulations remontent du début des années 1970, et qui avaient précisément pour objectif de remédier aux défaillances des outils et méthodes d’évaluation scientifique traditionnelles. La thèse est divisée en cinq parties. Commençant par une revue historique des modèles classiques des théories de la conception (design thinking) elle se concentre sur l’évolution des modalités de prise en compte de la durabilité. Dans cette perspective...

Sustainable design is fundamentally a subset of good design.The description of good design will eventually include criteria for the creation of a healthy environment and energy efficiency. These goals will be achieved by an emergent paradigm of design practice:integration.At every level design interests will come together to facilitate common goals for the creation of a rewarding present and a healthy future. Interdisciplinary design teams will flourish. Inter-accommodating and fluidly communicating political structures will grow. Coalescing social values and economic forces will propel integrated strategies. Unique and innovative solutions will increasingly become the objective. One eventual outcome of this integrated or sustainable design practice will be the development of buildings that produce more energy than they consume.; Le concept de durabilité dans la conception (design) est une des contraintes conceptuelles fondamentales que l’on trouve dans une bonne conception. La description d’une bonne conception englobera éventuellement des critères de santé environnementale et de rendement énergétique. Ces buts seront atteints par la voie d’un paradigme émergent dans la pratique conceptuelle : l’intégration. À tous les niveaux...

Escopo. Foi feito um trabalho interdisciplinar que utilizou a Teoria de solução de problemas inventivos (TRIZ) e o Análise cognitivo de tarefas (ACT) para orientar o desenho de um cenário de aprendizagem para um museu de ciências naturais. Metodologia. Participaram 23 pessoas: seis engenheiros de sistemas, um engenheiro industrial, um engenheiro eléctrico, dois psicólogas, um biólogo, uma bioquímica, um físico, um técnico museológico, um historiador, um guia de museu, um desenhador gráfico e seis estudantes de engenheira. O processo de análise foi feito em duas fases. Na primeira, foi analisado o componente técnico do problema usando TRIZ, na segunda, foi analisado o componente educativo utilizando o ACT. Resultados. A aplicação de TRIZ permitiu identificar que o cenário de aprendizagem devia ser divertido, durável, de fácil uso e integração do uso de novas tecnologias com fins educativos, e que devia implicar pouca assistência dos guias do museu. O ACT possibilitou entender que a função principal do cenário de aprendizagem era promover a compreensão de conceitos involucrados na relação entre pessoas, pantanais e aves migratórias. Para isto, foi desenhada a estrutura de um videojogo educativo. Conclusão. O desenho de este videojogo prioriza os componentes educativos...

Artículo de publicación ISI; The use of a durable good is limited by both its physical life and usable life. For example, an electric-car battery can last for five years (physical life) or 100,000 miles (usable life), whichever comes first. We propose a framework for examining how a profit-maximizing firm might choose the usable life, physical life, and selling price of a durable good. The proposed framework considers differences in usage rates and product valuations by consumers and allows for the effects of technological constraints and product obsolescence on a product's usable and physical lives. Our main result characterizes a relationship between optimal price, cost elasticities, and opportunity costs associated with relaxing upper bounds on usable and physical lives. We describe conditions under which either usable life or physical life, or both, obtains its maximum possible values; examine why a firm might devote effort to relaxing nonbinding constraints on usable life or physical life; consider when price cuts might be accompanied with product improvements; and examine how a firm might be able to cross-subsidize product improvements.

Driven by the demand for the commercialization of fuel cell (FC) technology, we describe the design and fabrication of a highly durable FC electrocatalyst based on double-polymer-coated carbon nanotubes for use in polymer electrolyte membrane fuel cells. The fabricated electrocatalyst is composed of Pt-deposited polybenzimidazole-coated carbon nanotubes, which are further coated with Nafion. By using this electrocatalyst, a high FC performance with a power density of 375 mW/cm2 (at 70 ˚C, 50% relative humidity using air (cathode)/H2(anode)) was obtained, and a remarkable durability of 500,000 accelerated potential cycles was recorded with only a 5% loss of the initial FC potential and 20% loss of the maximum power density, which were far superior properties compared to those of the membrane electrode assembly prepared using carbon black in place of the carbon nanotubes. The present study indicates that the prepared highly durable fuel cell electrocatalyst is a promising material for the next generation of PEMFCs.

This is the author accepted manuscript. The final version is available from INFORMS via http://dx.doi.org/10.1287/msom.2015.0554; An extensive body of literature argues for the benefits of planned obsolescence, the strategy of designing products with low durability to induce repeat purchases from the consumers, and allow the firm to sell a larger volume. Yet, several firms avoid planned obsolescence and instead offer products with high durability. In this paper, we offer a demand-side rationale for a high-durability product design strategy: the exclusivity-seeking consumer behavior associated with conspicuous consumption. In the presence of consumers who value exclusivity, we find that firms benefit from designing products with higher durability in conjunction with a high-price, low-volume introduction strategy. A higher durability in such a context leads to greater resale value, allowing the firm to charge a higher price and lower the sales volume to achieve the product exclusivity valued by the consumers. This contrasts with the planned obsolescence strategy that capitalizes on the high sales volume achieved by setting a low new product price. We also show that offering higher durability and charging a higher price are complementary levers to respond to consumers who value exclusivity. Our analysis unearths insights regarding the effect of exclusivity-seeking behavior on a firm's demand and pricing. We show that firms' durability choice may explain the joint increase in price and demand for conspicuous goods.

Kansei Engineering, a Japanese design method used to translate feelings into product parameters, was used to look at the mobile phone design features of the Motorola Charm, Samsung t249, and HTC HD7 in the United States. Preferences of four design features (shape, material, LCD screen size, and navigation tools) were explored in a sample population of twenty-five university students in a private Northeastern university. Six kanseis/feelings elicited by phones were determined to be important to this group: (1) Attractive, (2) Cool, (3) Durable, (4) Ergonomic, (5) Modern, and (6) User-friendly. A (generic) phone with a rectangular shape, comprised mostly of metal-like and glass material, with a large LCD screen and navigation via a touchpad was determined to be the most ideal and strongly perceived to elicit many of these kanseis. After exploring the cultural sub-groups of this sample, it was determined that there are significant cultural group differences between Chinese participants and both American and Indian participants, mainly when considering the durability (p=.008) and coolness (p=.034) of the phone feature set.
