Sustainability informs the framework for a seminar that we teach for junior and senior undergraduates entitled "The Ethics and Economics of Sustainable Societies." One of the class requirements has each student research and write a life-cycle case study, an exercise in which they trace the full, or partial, life-cycle of some product with which they are familiar. Students are expected to examine the economic, ethical, and ecological implications along each step in the life-cycle of (...) the product. We believe that life-cyclecases in general are very helpful in revealing the full economic, ethical, and ecological consequences of product development, marketing, use, and disposal. We also believe that asking students to research the product themselves provides additional pedagogical benefits. After a brief review of the philosophical case for our alternative view of corporate social responsibility, we will describe the life-cycle case method, offer several examples from our own classes, and make the case for the pedagogical benefits of this approach.

Failure is a central notion both in ethics of engineering and in engineering practice. Engineers devote considerable resources to assure their products will not fail and considerable progress has been made in the development of tools and methods for understanding and avoiding failure. Engineering ethics, on the other hand, is concerned with the moral and social aspects related to the causes and consequences of technological failures. But what is meant by failure, and what does it mean that a failure has (...) occurred? The subject of this paper is how engineers use and define this notion. Although a traditional definition of failure can be identified that is shared by a large part of the engineering community, the literature shows that engineers are willing to consider as failures also events and circumstance that are at odds with this traditional definition. These cases violate one or more of three assumptions made by the traditional approach to failure. An alternative approach, inspired by the notion of product lifecycle, is proposed which dispenses with these assumptions. Besides being able to address the traditional cases of failure, it can deal successfully with the problematic cases. The adoption of a lifecycle perspective allows the introduction of a clearer notion of failure and allows a classification of failure phenomena that takes into account the roles of stakeholders involved in the various stages of a product lifecycle.

We investigate the context of discovery of two significant achievements of twentieth century biochemistry: the chemiosmotic mechanism of oxidative phosphorylation and the dark reaction of photosynthesis. The pursuit of these problems involved discovery strategies such as the transfer, recombination and reversal of previous causal and mechanistic knowledge in biochemistry. We study the operation and scope of these strategies by careful historical analysis, reaching a number of systematic conclusions: even basic strategies can illuminate “hard cases” of scientific discovery that go (...) far beyond simple extrapolation or analogy; the causal–mechanistic approach to discovery permits a middle course between the extremes of a completely substrate-neutral and a completely domain-specific view of scientific discovery; the existing literature on mechanism discovery underemphasizes the role of combinatorial approaches in defining and exploring search spaces of possible problem solutions; there is a subtle interplay between a fine-grained mechanistic and a more coarse-grained causal level of analysis, and both are needed to make discovery processes intelligible.

The aim of the article. The aim of the article is to identify the components of social and economic systems lifecycle. To achieve this aim, the article describes the traits and characteristics of the system, determines the features of social and economic systems functioning and is applied a systematic approach in the study of their lifecycle. The results of the analysis. It is determined that the development of social and economic systems has signs of (...) cyclicity and is explained methodologically by the axiomatics, rules and laws. Understanding of circular patterns has been formed long ago and now is recorded by scientists monitoring the properties of natural and artificial environment of human activity. During the study, it was found out that in scientific literature there is no unified description of the lifecycle elements of social and economic systems at personal, micro, meso, macro and global levels. The paper investigates the cyclical patterns in multilevel social and economic systems for a human, employee, family, product, company, city, industry, elite, macroeconomic indicators, humanity, global processes, global economic system and the Universe. It is noted that at grass-roots administrative levels of the global environment of a human life activity system, a thesis about the cyclicity of development and the stages of the lifecycle is considered by a wide circle of scientists and is doubtless. On hierarchically higher management levels of the global environment of human activity system, the scientists noticed the similar patterns of the cyclical nature. Problematic and discussion questions about cyclic development of social and economic systems are identified: the uncertainty of the driving force source of repeated changes; the vague distinction between systemic (internal) and off-system (external) influence on development; the lack of a unified description of development nature at different managerial levels; the use of different descriptive terms for the same constituent elements of repeated changes (period, stage, phase, wave, cycle); the uncertainty of the number of repeated changes constituent elements; the absence of an identification mechanism of the exact time of changes in the constituent elements of repeated changes; the surface description of out-of-system period of the subjects activity («before-system» period of creation and «after-system» period of liquidation); attaching more importance to primary and less importance to ultimate component elements of the repeated changes; the lack of reliable mechanism for predicting and forecasting the dynamics of constituent components of repeated changes. It is noted that all social and economic systems are developed within repeated changes and they have the same attributes of cyclicity: the fluctuation of indicators is marked that characterize the condition of the subject; the presence of system (from creation to liquidation) and out-of-system (creation – «design» and liquidation – «disposal») periods are noted; the subjects are created by the actions of other subjects (that is, subjects do not arise «out of nowhere», but are the result of actions of other subjects – «constructors»); after cessation of subjects functioning, their resources are used by other subjects (that is, the subjects do not disappear «nowhere», and they are transformed into the resources of other subjects – «recovery»); a unidirectional lifecycle from «birth» to «death» is observed in the subjects; the subjects do not have to undergo the whole lifecycle (each time might be the last); the subjects display similar changes of the indicators during their activity; ascending, peak and descending fluctuations of indicators are observed in the subjects; minor fluctuations occur in the constituent elements; the subjects have individual nature of indicator fluctuations and duration of activity. Conclusions and directions of further researches. The scientific novelty of the study is identification structure of lifecycle of social and economic system with definitions of: common («before-system state», «growth», «stabilization», «reduction», «after-system state») and specific («creation», «slow growth», «rapid growth», «growth stabilization», «short stabilization», «rapid reduction», «slow reduction», «liquidation») constituent elements of repeated changes; marginal borders of indicators; dynamics of constituent elements of lifecycle; key points of changing nature of the indicators dynamics. Identification of the lifecycle of social and economic systems characterizes potentially possible limits of their activity in time and provides the possibility of further research of aspects of the cyclical development for methodological basis formation and the development of applied measures of systemic development in the areas of marketing and management innovations.

In multi-stakeholder networks, actors from civil society, business and governmental institutions come together in order to find a common solution to a problem that affects all of them. Problems approached by such networks often affect people across national boundaries, tend to be very complex and are not sufficiently understood. In multi-stakeholder networks, information concerning a problem is gathered from different sources, learning takes place, conflicts between participants are addressed and cooperation is sought. Corporations are key actors in many networks, because (...) the problems addressed are frequently related to business activities. The aim of this article is to conceptualise multi-stakeholder networks by proposing a problem-centred stakeholder definition. From an analysis of several case studies, a lifecycle model is deduced that distinguishes seven phases: initiation, acquaintance, first and second agreement, implementation, consolidation and institutionalisation.

Product safety has always been one of the main problems in engineering ethics. At times it has been discussed as primarily a problem of engineering ethics. However the right to safety is one of the four fundamental consumer rights and so it is an important theme also in business ethics. At the same time the problem of product safety is inseparably connected with business effectiveness: how much can we spend on product safety without making our production unprofitable?Below we will present (...) a possible treatment of the safety problem in teaching business ethics to post-graduate industrial engineering students – as we deal with the problem in Tallinn Technical University.

The manufacturing industry is evolving rapidly, becoming more complex, more interconnected, and more geographically distributed. Competitive pressure and diversity of consumer demand are driving manufacturing companies to rely more and more on improved knowledge management practices. As a result, multiple software systems are being created to support the integration of data across the product lifecycle. Unfortunately, these systems manifest a low degree of interoperability, and this creates problems, for instance when different enterprises or different branches of an (...) enterprise interact. Common ontologies (consensus-based controlled vocabularies) have proved themselves in various domains as a valuable tool for solving such problems. In this paper, we present a consensus-based Additive Manufacturing Ontology (AMO) and illustrate its application in promoting re-usability in the field of dentistry product manufacturing. (shrink)
The ability to access and share data is key to optimizing and streamlining any industrial production process. Unfortunately, the manufacturing industry is stymied by a lack of interoperability among the systems by which data are produced and managed, and this is true both within and across organizations. In this paper, we describe our work to address this problem through the creation of a suite of modular ontologies representing the product lifecycle and its successive phases, from design to (...) end of life. We call this suite the Product LifeCycle (PLC) Ontologies. The suite extends proximately from The Common Core Ontologies (CCO) used widely in defense and intelligence circles, and ultimately from the Basic Formal Ontology (BFO), which serves as top level ontology for the CCO and for some 300 further ontologies. The PLC Ontologies were developed together, but they have been factored to cover particular domains such as design, manufacturing processes, and tools. We argue that these ontologies, when used together with standard public domain alignment and browsing tools created within the context of the Semantic Web, may offer a low-cost approach to solving increasingly costly problems of data management in the manufacturing industry.

This article reviews the public health and environmental regulations applicable to nanotechnology using a lifecycle model from basic research through end-of-life for products. Given nanotechnology's immense promise and public investment, regulations are important, balancing risk with the public good. Trading zones and earth systems engineering management assist in explaining potential solutions to gaps in an otherwise complex, overlapping regulatory system.
This papers attempts to bridge business ethics to corporate social responsibility including the social and environmental dimensions. The objective of the paper is to suggest an improvement of the most commonly used corporate environmental management tool, the LifeCycle Assessment (LCA). The method includes two stages. First, more phases are added to the life-cycle of a product. Second, social criteria that measure the social performance of a product are introduced. An application of this “extended” LCA tool (...) is given. (shrink)
In The Symbolic Species Terrence Deacon identifies human verbal language acquisition as the first and foremost evolutionary threshold where symbol use happens, with all the concomitant adaptive advantages it affords, but along with these advantages in this book and elsewhere he alludes to certain disadvantages that result from symbols. To describe these disadvantages he uses words like maladaptation, parasitism, cognitive penumbra, and other hyperbolic terms. He does so offhandedly, either in connection with the results of some laboratory experiments, or simply (...) in disconnected ominous generalizations, but never justifies these sign effects within the dominantly Peircean model of language acquisition that gives the book its title. In later works Deacon attempts to contextualize these generalizations within Richard Dawkins’ theory of the meme. Deacon is sometimes disparaged for his supposedly imprecise or incorrect use of the sign theory of Charles Peirce to defend his claims about memes and symbols. The problem is not that Peirce should not be used in this way. In fact Deacon’s book is a singular achievement in the application of Peirce. The problem is that Deacon’s Peircean model is too simple. In fact Deacon’s claim about the possible disadvantages of symbol use can be reinforced with a closer look at the mature, turn-of-the-century Peircean sign model. This preserves the theoretical integrity of The Symbolic Species and clarifies the relation between memes and signs. (shrink)
Productive work on societal implications needs to be engaged with the research from the start. Ethicists need to go into the lab to understand what's possible. Scientists and engineers need to engage with humanists to start thinking about this aspect of their work. Only thus, working together in dialog, will we make genuine progress on the societal and ethical issues that nanotechnology poses.Davis Baird, in testimony before the Senate Committee on Commerce, Science and Transportation, May 1, 2003Federal funding of the (...) National Nanotechnology Initiative has averaged roughly $1 billion annually for the last three years, from 2004 to 2006. Society is poised to see more realistic nano-scale devices enter the marketplace, along with futuristic depictions of nanotechnology.

It has become a standard for researchers carrying out biotechnology projects to do a lifecycle assessment. This is a process for assessing the environmental impact of a technology, product or policy. Doing so is no simple matter, and in the last decades, a rich set of methodologies has developed around LCA. However, the proper methods and meanings of the process remain contested. Preceding the development of the international standard that now governs LCA, there was a lively debate (...) in the academic community about the inclusion of ‘values’ within the process. We revisit this debate and reconsider the way forward for LCA. We set out ways in which those outside of science can provide input into LCAs by informing the value assumptions at stake. At the same time, we will emphasize that the role of those within the scientific community need not involve value-free inquiry. We carry out this exploration through a case study of a particular technology project that sought ways to produce industrial and consumer products from algal oils. (shrink)
Different stages of the product and industry lifecycle has been argued to be an important factor in shaping firms’ strategic actions, as the lifecycle influence the firms’ sales, profit, product innovation, marketing mix and differentiation strategies. Drawing on the theory of industry lifecycle , this article examines how the ILC influences firms’ corporate social responsibility performance in the context of global procurement transactions. The findings suggest that mature industries have much greater (...) levels of responsible procurement processes, compared to rapid growing and declining industries. The authors conclude that CSR in procurement transactions is a trait of changes in the strategic behaviour of firms, as they progress from the ILC stage of growth to maturity and decline, rather than being a by-product of supply chain sophistication, which also develops along the ILC.

A model is proposed which implicates molecular recognition systems as the major controlling factors in lifecycle expression. It is envisaged that such systems are important in immune functioning and catabolic, metabolic molecule recognition at both inter- and intea-cellular level. These recognition systems have the following characteristics: Specific recognition molecules , e.g. vertebrate antibodies, invertebrate agglutinins and plant agglutinins may recognise specific substances, e.g. antigens, catabolic and metabolic molecules. The range of possible recognisable substances is very wide and (...) variable. The recognisers may themselves be recognised by other recognisers. Recognisers are usually produced in large amounts only on presentation of the appropriate recognisable molecule. The progressive introduction of new recognisable molecules increases the recogniser interaction, this interaction causing depression of some recogniser types and facilitation of other types among which may be recognisers specific for self components . Low juvenile viability is associated with a restricted range of available recognisers, high adult viability with increasing recogniser range and some auto-immunity/immune depression, senescence with a wide range of available recognisers and extensive auto-immunity/immune depression.Lifecycle patterns and their control are discussed. It is suggested control mechanisms may include: Dietary restriction and in some periods complete nutritional abstinence. Specific recogniser depression, genes implicated here are the various antigens found on cell surfaces, in the serum and in various body fluids of vertebrates, e.g. ABO, MNSs, P, Rh, Le and other blood groups, the ABO and Le secretor antigens and the HL-A antigens. In addition the immune response and mixed lymphocyte culture loci are implicated. Finally lifecycle control is discussed with relation to sexual selection. (shrink)
Interdisciplinary research is frequently viewed as an important component of the research landscape through its innovative ability to integrate knowledge from different areas. However, support for interdisciplinary research is often strategic rhetoric, with policy-makers and universities frequently adopting practices that favour disciplinary performance. We argue that disciplinary and interdisciplinary research are complementary, and we develop a simple framework that demonstrates this for a semi-permanent interdisciplinary research field. We argue that the presence of communicating infrastructures fosters communication and integration between disciplines (...) and the interdisciplinary research field to generate innovative knowledge. We apply this to the experience of economic history in Australia in the second half of the twentieth century to demonstrate the lifecycle of a semi-permanent interdisciplinary research field.

We suggest that morbid jealousy falls on the extreme end of a jealousy continuum. Thus, many features associated with normal jealousy will be present in individuals diagnosed with morbid jealousy. We apply Boyer & Lienard's (B&L's) prediction one (P1; target article, sect. 7.1) to morbid jealousy, suggesting that fitness-related life-cycle dimensions predict sensitivity to cues, and frequency, intensity, and content of intrusive thoughts of partner infidelity.

It is a commonplace in the history of science that reputations of scientists play important roles in the stories of scientific knowledge. I argue that to fully understand these roles we should see reputations as produced by communicative acts, consider how reputations become known about, and study the factors influencing such processes. I reapply James Secord's ‘knowledge-in-transit’ approach; in addition to scientific knowledge, I also examine how ‘biographical knowledge’ of individuals is constructed through communications and shaped by communicative contexts. My (...) case study is Carl Sagan, widely discussed – amongst scientists, media professionals and publics – for his skill as a charismatic popularizer, his perceived arrogance, his political activism, and his debated merit as a researcher. By examining how aspects of Sagan's reputation circulated alongside his scientific work – rather than existing as a static context for his scientific work – I show how different forms of knowledge influence each other as they circulate.

Over the last 20+ years, multinational corporations have been confronted with accusations of abuse of market power and unfair and unethical business conduct especially as it relates to their overseas operations and supply chain management. These accusations include, among others, worker exploitation in terms of unfairly low wages, excessive work hours, and unsafe work environment; pollution and contamination of air, ground water and land resources; and, undermining the ability of natural government to protect the well-being of their citizens. MNCs have (...) responded to these accusations by creating voluntary codes of conduct which commit them to specific standards for addressing these issues. These codes are created at both the industry-wide and the individual company level. Unfortunately, these codes have generated little credibility and public trust because their compliance claims cannot be independently verified, and they lack transparency and full public disclosure. In this article, we present a case study of the voluntary code of conduct by Mattel, Inc., the world’s largest toy company. The code, called the Global Manufacturing Principles, confronts the general criticism leveled against voluntary codes of conduct by creating detailed standards of compliance, independent external monitoring of the company’s compliance with its code of conduct, and making full, and uncensored public disclosure of the audit findings and company’s response in terms of remedial action. We present a detailed account of how Mattel’s voluntary code of conduct was created, implemented, and ultimately abandoned over 9 years. We provide an evaluative analysis of the company’s GMP compliance throughout its life span, which suggests a bell-shaped curve, where early top management commitments were met with pockets of resistance from operational groups, who were concerned about balancing GMP compliance efforts with traditional performance criteria. The early stage response from Mattel’s top management was quick and supported with the requisite resources. As a result, the compliance process accelerated, becoming increasingly more robust and effective. The success of code compliance and increased transparency in public disclosure energized field managers with a sense of professional satisfaction and publicly recognized accomplishments. The decline in GMP compliance was equally steep. When all the easily attainable targets had been reached at the company-operated plants, addressing vendor plants’ compliance presented a new set of challenges, which taxed corporate resources and management commitment. It would seem that value-based and ethics-oriented considerations, i.e., doing the right thing for the right reason, were no longer the driving force for Mattel’s management. Mattel did not see any economic benefit from its proactive stance, when competitors did not seem to suffer adverse consequences for not following suit. The final contributing factor to the code’s abandonment was a widely publicized series of product recalls which absorbed top management’s attention. (shrink)

The paper reconstructs the read thread that links the information revolution, the information concept and information ethics in Floridi’s philosophy of information. In doing so, it acknowledges the grand attempt but doubts whether this attempt is up to the state of affairs concerning the actual point human history has reached. It contends that the information age is rather conceivable as a critical stage in which human evolution as a whole is at stake. The mastering of this crisis depends on an (...) appropriate shaping of Information and Communication Technologies which requires ethical considerations. In this respect, Floridi’s notion of the fourth revolution, his assumption of the management of the lifecycle of information, and his ontocentric macroethics will be discussed in the light of the term “scientific-technological revolution”, the idea of a noogenesis, a new way of thinking and new weltanschauung, the concept of friction in social and physical aspects, the concept of collective intelligence and its application to the Internet and last, but not least, the vision of a Global Sustainable Information Society.

Definitive diagnosis of malaria requires the demonstration through laboratory tests of the presence within the patient of malaria parasites or their components. Since malaria parasites can be present even in the absence of malaria manifestations, and since symptoms of malaria can be manifested even in the absence of malaria parasites, malaria diagnosis raises important issues for the adequate understanding of disease, etiology and diagnosis. One approach to the resolution of these issues adopts a realist view, according to which the needed (...) clarifications will be derived from a careful representation of the entities on the side of the patient which form the ultimate truthmakers for clinical statements. We here address a challenge to this realist approach relating to the diagnosis of malaria, and show how this challenge can be resolved by appeal to Basic Formal Ontology (BFO) and to the Ontology for General Medical Science (OGMS) constructed in its terms.

The three most common responses to Taurek’s ‘numbers problem’ are saving the greater number, equal chance lotteries and weighted lotteries. Weighted lotteries have perhaps received the least support, having been criticized by Scanlon What We Owe to Each Other ( 1998 ) and Hirose ‘Fairness in Life and Death Cases’ ( 2007 ). This article considers these objections in turn, and argues that they do not succeed in refuting the fairness of a weighted lottery, which remains a potential (...) solution to cases of conflict. Moreover, it shows how these responses actually lead to a new argument for weighted lotteries, appealing to fairness and Pareto-optimality. (shrink)
