In recent years the demands of users and the social problems have been diverse. In design, the diverse demands of users and problems of the society have created increasingly complex design problems. Therefore, it is important to understand values and images of the design objects and analyze the relation among design objects, human beings and its environment to respond to the complicated design problems. A number of design modeling methods that realize above points have been proposed. Consequently, it is necessary for designers and engineers to derivate the exact design solution that responds to the complicated design problems. However, the framework of design modeling methods in design has not been established. Moreover, most of the current studies on the methods only respond to the problems in each aspect of design [1]. Therefore, designers and engineers apply the design modeling methods in each design process based on their knowledge and experiences. The guideline of selection for the application of design modeling methods has not been shown. Consequently, the guideline for selecting the design modeling methods is needed for designers and engineers to apply the methods appropriately in design.

Nowadays safety is a hot topic, damage inflicted to human beings is intolerable. Fire safety is a big concernin industrial areas, but in residential areas a lot less precautions are in place. Therefore a new type of fireextinguisher should be developed that should encourage the installation of fire extinguishers in commercialenvironments and at home. The design of this fire extinguisher has to answer to a lot of demands. From alegal point of view, the extinguisher has to comply with the PED regulations and the EN 3 standard. Extrademands are, given the purpose, superb performance, great ergonomics and an attractive visual design.One of the steps in the design process is to make a material selection based on needed and desiredproperties of materials. Also the possible processes for manufacturing are an important parameter.

Value Model

This paper is dealing with the problem of steering the conceptual design by value. Indeed, the preliminary phase of the design process, which generates the innovative concepts that will be developed in detail, already defines broadly the created value of an innovation project. Contrarily to the detailed design that consists in design solutions refinement for well defined performances increase, the conceptual design is characterized by the fact that the design objects, like the design problems, the design concepts and knowledge, are not frozen, known or precised, and have to be defined progressively in a value creation way for customers and stakeholders. Since there are few works on this issue, we try then to suggest a conceptual design process based on the capture and evaluation of the generated intermediate objects for the maximization of the created value of this phase, and so of an innovative project. A descriptive model, a value model and a prescriptive production model of the intermediate objects are thus built and explained.

AbstractDesigners faced with complex design problems use decomposition strategies to tackle manageable sub-problems. Recomposition strategies aims at synthesizing sub-solutions into a unique design proposal. Design theory describes the design process as a combination of decomposition and recomposition strategies. In this paper, we explore dynamic patterns of decomposition and recomposition strategies of design teams. Data were collected from 9 teams of professional engineers. Using protocol analysis, we examined the dominance of decomposition and recomposition strategies over time and the correlations between each strategy and design processes such as analysis, synthesis, evaluation. We expected decomposition strategies to peak early in the design process and decay overtime. Instead, teams maintain decomposition and recomposition strategies consistently during the design process. We observed fast iteration of both strategies over a one hour-long design session. The research presented provides an empirical foundation to model the behaviour of professional engineering teams, and first insights to refine theoretical understanding of the use decomposition and recomposition strategies in design practice.

Measure Of Uncertainty

Early stages of engineering design processes are characterized by high levels of uncertainty due to incomplete knowledge. As the design progresses, additional information is externally added or internally generated within the design process. As a result, the design solution becomes increasingly well-defined and the uncertainty of the problem reduces, diminishing to zero at the end of the process when the design is fully defined. In this research a measure of uncertainty is proposed for a class of engineering design problems called discrete design problems. Previously, three components of complexity in engineering design, namely, size, coupling and solvability, were identified. In this research uncertainty is measured in terms of the number of design variables (size) and the dependency between the variables (coupling). The solvability of each variable is assumed to be uniform for the sake of simplicity. The dependency between two variables is measured as the effect of a decision made on one variable on the solution options available to the other variable. A measure of uncertainty is developed based on this premise, and applied to an example problem to monitor uncertainty reduction through the design process. Results are used to identify and compare three task-sequencing strategies in engineering design.

Complex design problems are typically decomposed into smaller design problems that are solved by domain-specific experts who must then coordinate their solutions into a satisfactory system-wide solution. In set-based collaborative design, collaborating engineers coordinate themselves by communicating multiple design alternatives at each step of the design process. The goal in set-based collaborative design is to spend additional resources exploring multiple options in the early stages of the design process, in exchange for less iteration in the latter stages, when iterative rework tends to be most expensive. Several methods have been proposed for representing sets of designs, including intervals, surrogate models, fuzzy membership functions, and probability distributions. In this paper, we introduce the use of Bayesian networks for capturing sets of promising designs, thereby classifying the design space into satisfactory and unsatisfactory regions. The method is compared to intervals in terms of its capacity to accurately classify satisfactory design regions as a function of the number of available data points. A simplified, multilevel design problem for an unmanned aerial vehicle is presented as the motivating example.

AbstractLookism is a term used to describe discrimination based on the physical appearance of a person. We suppose that the social impact of lookism is a philosophical issue, because, from this perspective, attractive people have an advantage over others. The first line of our argumentation involves the issue of lookism as a global ethical and aesthetical phenomenon. A person’s attractiveness has a significant impact on the social and public status of this individual. The common view in society is that it is good to be more attractive and healthier. This concept generates several ethical questions about human aesthetical identity, health, authenticity, and integrity in society. It seems that this unequal treatment causes discrimination, diminishes self-confidence, and lowers the chance of a job or social enforcement for many human beings. Currently, aesthetic improvements are being made through plastic surgery. There is no place on the human body that we cannot improve with plastic surgery or aesthetic medicine. We should not forget that it may result in the problem of elitism, in dividing people into primary and secondary categories. The second line of our argumentation involves a particular case of lookism: Melanie Gaydos. A woman that is considered to be a model with a unique look.

This paper seeks to understand why there has been an increase in photographic images exposing military violence or displaying bodies killed by military forces and how they can freely circulate in the public without being censored or kept hidden. In other words, it aims to analyze this particular issue as a symptom of the emergence of new wars and a new regime of their visual representation. Within this framework, it attempts to relate two kinds of literature that are namely the history of war and war photography with the bridge of theoretical discussions on the real, its photographic representation, power, and violence.  Rather than systematic empirical analysis, the paper is based on a theoretical attempt which is reflected on some socio-political observations in the Middle East where there has been ongoing wars or new wars. The core discussion of the paper is supported by a brief analysis of some illustrative photographic images that are served through the social media under the circumstances of war for instance in Turkey between Turkish military troops and the Kurdish militants. The paper concludes that in line with the process of dissolution/transformation of the old nation-state formations and globalization, the mechanism and mode of power have also transformed to the extent that it resulted in the emergence of new wars. This is one dynamic that we need to recognize in relation to the above-mentioned question, the other is the impact of social media in not only delivering but also receiving war photographies. Today these changes have led the emergence of new machinery of power in which the old modern visual/photographic techniques of representing wars without human beings, torture, and violence through censorship began to be employed alongside medieval power techniques of a visual exhibition of tortures and violence.

What is property, and why does our species happen to have it? The Property Species explores how Homo sapiens acquires, perceives, and knows the custom of property, and why it might be relevant for understanding how property works in the twenty-first century. Arguing from some hard-to-dispute facts that neither the natural sciences nor the humanities—nor the social sciences squarely in the middle—are synthesizing a full account of property, this book offers a cross-disciplinary compromise that is sure to be controversial: All human beings and only human beings have property in things, and at its core, property rests on custom, not rights. Such an alternative to conventional thinking contends that the origins of property lie not in food, mates, territory, or land, but in the very human act of creating, with symbolic thought, something new that did not previously exist. Integrating cognitive linguistics with the philosophy of property and a fresh look at property disputes in the common law, this book makes the case that symbolic-thinking humans locate the meaning of property within a thing. The provocative implications are that property—not property rights—is an inherent fundamental principle of economics, and that legal realists and the bundle-of-sticks metaphor are wrong about the facts regarding property. Written by an economist who marvels at the natural history of humankind, the book is essential reading for experts and any reader who has wondered why people claim things as “Mine!,” and what that means for our humanity.

Magnanimity is a virtue that has led many lives. Foregrounded early on by Plato as the philosophical virtue par excellence, it became one of the crown jewels in Aristotle’s account of human excellence and was accorded an equally salient place by other ancient thinkers. One of the most distinctive elements of the ancient tradition to filter into the medieval Islamic and Christian worlds, it sparked important intellectual engagements there and went on to carve deep tracks through several later philosophies that inherited from this tradition. Under changing names, under reworked forms, it continued to breathe in the thought of Descartes and Hume, Kant and Nietzsche, and their successors. Its many lives have been joined by important continuities. Yet they have also been fragmented by discontinuities—discontinuities reflecting larger shifts in ethical perspectives and competing answers to questions about the nature of the good life, the moral nature of human beings, and their relationship to the social and natural world they inhabit. They have also been punctuated by moments of controversy in which the greatness of this vision of human greatness has itself been called into doubt. This volume provides a window to the complex trajectory of a virtue whose glitter has at times been as heady as it has been divisive. By exploring the many lives it has lived, we will be in a better position to decide whether and why this is a virtue we might still want to make central to our own ethical lives.

Although much of the social science literature supports the importance of community assets for success in many policy areas, these assets are often overlooked when selecting communities for new infrastructure facilities. Extensive collaboration is crucial for the success of environmental and economic projects, yet it often is not adequately addressed when making siting decisions for new projects. This article develops a social asset framework that includes social, creative, and human capital to inform site-selection decisions. This framework is applied to the Northwest Advanced Renewables Alliance project to assess community suitability for biofuel-related developments. This framework is the first to take all necessary community assets into account, providing insight into successful site selection beyond current models. The framework not only serves as a model for future biorefinery projects but also guides tasks that depend on informed location selection for success.
