The decolonial theory understands that Western Modernity keeps imposing itself through a triple mutually reinforcing and shaping imprisonment: coloniality of power, coloniality of knowledge, and coloniality of being. Technical design has an essential role in either maintaining or overcoming coloniality. In this article, two main approaches to decolonizing the technical design are presented. First is Yuk Hui’s and Ahmed Ansari’s proposals that, revisiting or recovering the different histories and philosophies of technology produced by humankind, intend to decolonize the minds of (...) philosophers and engineers/architects/designers as a pre-condition for such decolonial designs to take place. I call them top-down approaches. Second is some technical design initiatives that, being developed alongside marginalized/subalternate people, intend to co-construct decolonial sociotechnical solutions through a committed, decolonizing, and careful dialog of knowledge. I call them bottom-up approaches. Once that is done, the article’s second half derives ontological, epistemological, and political consequences from the conjugation of top-down and bottom-up approaches. Such consequences challenge some established or not yet entirely overcome understandings in the philosophy of technology and, in so doing, are meant to represent some steps in PT’s decolonization. Even though both top-down and bottom-up approaches are considered, the article’s main contributions are associated with decolonial technical design practices, whose methodologies and outcomes are important study cases for PT and whose practitioners can be taken as inspiring examples for philosophers who want to decolonize/enlarge PT or make it decolonial.

“Technological determinism” is predominantly employed as a critic’s term, used to dismiss certain classes of theoretical and empirical claims. Understood more productively as referring to claims that place a greater emphasis on the autonomous and social-shaping tendencies of technology, technological determinism is a valuable and prominent perspective. This article will advance our understanding of technological determinism through four contributions. First, I clarify some debates about technological determinism through an examination of the meaning of technology. Second, I parse the family of (...) claims related to technological determinism. Third, I note that constructivist and determinist insights may each be valid given particular scope conditions, the most prominent of which is the scale of analysis. Finally, I propose a theoretical microfoundation for technological determinism—military–economic adaptationism—in which economic and military competition constrain sociotechnical evolution to deterministic paths. This theory is a special case of a general theory—sociotechnical selectionism—which can be regarded as also including constructivist theories as special cases. Greater understanding of, respect for, and engagement with technological determinism will enhance the study of technology and our ability to shape our sociotechnical systems. (shrink)

Gothic cathedrals like Chartres were built in a discontinuous process by groups of masons using their own local knowledge, measures, and techniques. They had neither plans nor knowledge of structural mechanics. The success of the masons in building such large complex innovative structures lies in the use of templates, string, constructive geometry, and social organization to assemble a coherent whole from the messy heterogeneous practices of diverse groups of workers. Chartres resulted from the ad hoc accumulation of the work of (...) many men. (shrink)

A response to a recent critique by Cem Bozşahin of the theory of syntactic semantics as it applies to Helen Keller, and some applications of the theory to the philosophy of computer science.

How engineers know, and act on that knowledge, has a profound impact on society. Consequently, the analysis of engineering knowledge is one of the central challenges for the philosophy of engineering. In this article, we present a thematic multidisciplinary conceptual survey of engineering epistemology and identify key areas of research that are still to be comprehensively investigated. Themes are organized based on a survey of engineering epistemology including research from history, sociology, philosophy, design theory, and engineering itself. Five major interrelated (...) themes are identified: the relationship between scientific and engineering knowledge, engineering knowledge as a distinct field of study, the social epistemology of engineering, the relationship between engineering knowledge and its products, and the cognitive aspects of engineering knowledge. We discuss areas of potential future research that are underdeveloped or “undone.”. (shrink)

My dissertation explores the ways in which Rudolf Carnap sought to make philosophy scientific by further developing recent interpretive efforts to explain Carnap’s mature philosophical work as a form of engineering. It does this by looking in detail at his philosophical practice in his most sustained mature project, his work on pure and applied inductive logic. I, first, specify the sort of engineering Carnap is engaged in as involving an engineering design problem and then draw out the complications of design (...) problems from current work in history of engineering and technology studies. I then model Carnap’s practice based on those lessons and uncover ways in which Carnap’s technical work in inductive logic takes some of these lessons on board. This shows ways in which Carnap’s philosophical project subtly changes right through his late work on induction, providing an important corrective to interpretations that ignore the work on inductive logic. Specifically, I show that paying attention to the historical details of Carnap’s attempt to apply his work in inductive logic to decision theory and theoretical statistics in the 1950s and 1960s helps us understand how Carnap develops and rearticulates the philosophical point of the practical/theoretical distinction in his late work, offering thus a new interpretation of Carnap’s technical work within the broader context of philosophy of science and analytical philosophy in general.

Artefacts do not always do what they are supposed to, due to a variety of reasons, including manufacturing problems, poor maintenance, and normal wear-and-tear. Since software is an artefact, it should be subject to malfunctioning in the same sense in which other artefacts can malfunction. Yet, whether software is on a par with other artefacts when it comes to malfunctioning crucially depends on the abstraction used in the analysis. We distinguish between “negative” and “positive” notions of malfunction. A negative malfunction, (...) or dysfunction, occurs when an artefact token either does not or cannot do what it is supposed to. A positive malfunction, or misfunction, occurs when an artefact token may do what is supposed to but, at least occasionally, it also yields some unintended and undesirable effects. We argue that software, understood as type, may misfunction in some limited sense, but cannot dysfunction. Accordingly, one should distinguish software from other technical artefacts, in view of their design that makes dysfunction impossible for the former, while possible for the latter. (shrink)

The concept of tacit knowledge is widely used in social sciences to refer to all those knowledge that cannot be codified and have to be transferred by personal contacts. All this literature has been affected by two kind of biases : (1) the interest has been focused more on the result (tacit knowledge) than on the process (implicit learning); (2) tacit knowledge has been somehow reduced to physical skills or know-how; other possible forms of tacit knowledge have been neglected. These (...) two biases seem interconnected one with each other. A greater consideration of the role and relevance of implicit learning allows us to consider tacit knowledge as something more than pure physical skills or know how. This is the first step in order to develop more detailed categorisation of the different forms that tacit knowledge can assume. (shrink)

We argue that considering only a few ‘big’ ethical decisions in any engineering design process — both in education and practice — only reinforces the mistaken idea of engineering design as a series of independent sub-problems. Using data collected in engineering design organisations over a seven year period, we show how an ethical component to engineering decisions is much more pervasive. We distinguish three types of ethical justification for engineering decisions: (1) consequential, (2) deontological or non-consequential, and (3) virtue-based. We (...) find that although there is some evidence for engineering designers as ‘classic’ consequentialists, a more egocentric consequentialism would appear more fitting. We also explain how the idea of a ‘folk ethics’ — a justification in the second category that consciously weighs one thing with another — fits with the idea of the engineering design process as social negotiation rather than as technological progress.

Science and technology are so intertwined that technoscience has been argued to more accurately reflect the progress of science and its impact on society, and most socioscientific issues require technoscientific reasoning. Education policy documents have long noted that the general public lacks sufficient understanding of science and technology necessary for informed decision-making regarding socioscientific/technological issues. The science–technology–society movement and scholarship addressing socioscientific issues in science education reflect efforts in the science education community to promote more informed decision-making regarding such issues. (...) Now Science, Technology, Engineering, Mathematics education has emerged as a major reform movement impacting science education. STEM education efforts emphasize literacy across the disciplines of science, technology, engineering, and mathematics, but with rare exceptions, treat issues of technology superficially and uncritically. Informed decision-making regarding many personal and societal issues requires technological literacy beyond merely becoming an enthusiastic designer or skilled user of technology, but the science education community has given little attention to what such literacy entails. Here, we present results of an extensive review of the literature regarding the nature of technology in order to identify key issues among scholars who study technology. We then provide predominant perspectives among those scholars and suggest which identified NOT issues are most essential to address as part of STEM education efforts that seek to promote informed personal and societal decision-making.

In this paper we consider the emerging position in metaphysics that artifact functions characterize real kinds of artifacts. We analyze how it can circumvent an objection by David Wiggins (Sameness and substance renewed, 2001, 87) and then argue that this position, in comparison to expert judgments, amounts to an interesting fine-grained metaphysics: taking artifact functions as (part of the) essences of artifacts leads to distinctions between principles of activity of artifacts that experts in technology have not yet made. We show, (...) moreover, that our argument holds not only in the artifactual realm but also in biology: taking biological functions as (part of the) essences of organs leads to distinctions between principles of activity of organs that biological experts have not yet made. We run our argument on the basis of analyses of artifact and biological functions as developed in philosophy of technology and of biology, thus importing results obtained outside of metaphysics into the debate on ontological realism. In return, our argument shows that a position in metaphysics provides experts reason for trying to detect differences between principles of activities of artifacts and organs that have not been detected so far.

This second companion volume on engineering studies considers engineering practice including contextual analyses of engineering identity, epistemologies and values. Key overlapping questions examine such issues as an engineering identity, engineering self-understandings enacted in the professional world, distinctive characters of engineering knowledge and how engineering science and engineering design interact in practice. -/- Authors bring with them perspectives from their institutional homes in Europe, North America, Australia\ and Asia. The volume includes 24 contributions by more than 30 authors from engineering, the (...) social sciences and the humanities. Additional issues the chapters scrutinize include prominent norms of engineering, how they interact with the values of efficiency or environmental sustainability. A concluding set of articles considers the meaning of context more generally by asking if engineers create their own contexts or are they created by contexts. -/- Taken as a whole, this collection of original scholarly work is unique in its broad, multidisciplinary consideration of the changing character of engineering practice.

Experimentation represents today a ‘hot’ topic in computing. If experiments made with the support of computers, such as computer simulations, have received increasing attention from philosophers of science and technology, questions such as “what does it mean to do experiments in computer science and engineering and what are their benefits?” emerged only recently as central in the debate over the disciplinary status of the discipline. In this work we aim at showing, also by means of paradigmatic examples, how the traditional (...) notion of controlled experiment should be revised to take into account a part of the experimental practice in computing along the lines of experimentation as exploration. Taking inspiration from the discussion on exploratory experimentation in the philosophy of science—experimentation that is not theory-driven—we advance the idea of explorative experiments that, although not new, can contribute to enlarge the debate about the nature and role of experimental methods in computing. In order to further refine this concept we recast explorative experiments as socio-technical experiments, that test new technologies in their socio-technical contexts. We suggest that, when experiments are explorative, control should be intended in a posteriori form, in opposition to the a priori form that usually takes place in traditional experimental contexts.

A wide variety of skills, abilities and knowledge are used in technological activities such as engineering design. Together, they enable problem solving and artefact creation. Gilbert Ryle’s division of knowledge into knowing how and knowing that is often referred to when discussing this technological knowledge. Ryle’s view has been questioned and criticised by those who claim that there is only one type, for instance, Jason Stanley and Timothy Williamson who claim that knowing how is really a form of knowing that (...) and Stephen Hetherington who claims that knowing that is knowing how. Neither Ryle himself nor any of his critics have discussed technological knowledge. Exposing both Ryle’s and his critics’ ideas to technological knowledge show that there are strong reasons to keep the knowing how–knowing that dichotomy in technological contexts. The main reasons are that they are justified in different ways, that Stanley’s and Williamson’s ideas have great difficulties to account for learning of technological knowing how through training, and that knowing that is susceptible to Gettier problems, which technological knowing how is not.

Tacit knowledge is widely acknowledged to be an important component of innovation, but such recognition is rarely accompanied by more detailed explanations about the nature of tacit knowledge, why such knowledge is significant, how it becomes codified or whether there may be limits to codification. This paper attempts to fill some of the gaps, drawing on a recent study of university/industry links in three emerging technologies. It concludes that tacit knowledge, which can only be transmitted through personal interaction, will continue (...) to play an important role in innovation. This derives from a variety of reasons, but most significant are the complexity of systems and the emergence of new technologies. (shrink)

As the principle of timing or opportunity,kairos serves both as a powerful theme within technological discourse and as an analytical concept that explains some of the suasory force by which such discourse maintains itself and its position in our culture. This essay makes a case for a rhetoric of technology that is distinct from the rhetoric of science and illustrates the value of the classical vocabulary for understanding contemporary rhetoric. This case is made by examining images and models of technological (...) change that underlie and justify the thematizations ofkairos that appear in so much technological discourse and by exploring the phenomenon of “technological forecasting,” in which the characterization and construction of moments in the present are crucial to the projection of the future. One example of forecasting is examined in detail: the Japanese “Fifth Generation” computer project, which illustrates the twin themes of opportunity and threat. (shrink)

The following article treats the 'applicational turn' of modern fluid dynamics as it set in at the beginning of the 20th century with Ludwig Prandtl's concept of the boundary layer. It seeks to show that there is much more to applying a theory in a highly mathematical field like fluid dynamics than deriving a special case from a general explanatory theory under particular antecedent conditions. In Prandtl's case, the decisive move was to introduce a model that provided a physical/causal conception (...) of viscous flow at high Reynolds numbers. It facilitated an approximate solution to the Navier-Stokes equations, which in turn gave rise to many special applications. After a detailed account of Prandtl's achievement, the article discusses the role of the physical model and its experimental and mathematical significance. It is shown that the mathematical simplification provided by the physical model greatly expanded the explanatory capacity of the theory which the Navier-Stokes equations alone could not provide.

Unlike basic sciences, scientific research in advanced technologies aims to explain, predict, and (mathematically) describe not phenomena in nature, but phenomena in technological artefacts, thereby producing knowledge that is utilized in technological design. This article first explains why the covering-law view of applying science is inadequate for characterizing this research practice. Instead, the covering-law approach and causal explanation are integrated in this practice. Ludwig Prandtl's approach to concrete fluid flows is used as an example of scientific research in the engineering (...) sciences. A methodology of distinguishing between regions in space and/or phases in time that show distinct physical behaviours is specific to this research practice. Accordingly, two types of models specific to the engineering sciences are introduced. The diagrammatic model represents the causal explanation of physical behaviour in distinct spatial regions or time phases; the nomo-mathematical model represents the phenomenon in terms of a set of mathematically formulated laws.

This article aims to answer what I call the “constitution question of engineering modeling”: in virtue of what does an engineering model model its target system? To do so, I will offer a category-theoretic, structuralist account of design, using the olog framework. Drawing on this account, I will conclude that engineering and scientific models are not only cognitively but also representationally indistinguishable. I will finally propose an axiological criterion for distinguishing scientific from engineering modeling.

Some philosophers argue that we should eschew cross-explanatory integrations of mechanistic, dynamicist, and psychological explanations in cognitive science, because, unlike integrations of mechanistic explanations, they do not deliver genuine, cognitive scientific explanations. Here I challenge this claim by comparing the theoretical virtues of both kinds of explanatory integrations. I first identify two theoretical virtues of integrations of mechanistic explanations—unification and greater qualitative parsimony—and argue that no cross-explanatory integration could have such virtues. However, I go on to argue that this is (...) only a problem for those who think that cognitive science aims to specify one fundamental structure responsible for cognition. For those who do not, cross-explanatory integration will have at least two theoretical virtues to a greater extent than integrations of mechanistic explanations: explanatory depth and applicability. I conclude that one’s views about explanatory integration in cognitive science cannot be segregated from one’s views about the explanatory task of cognitive science. (shrink)

As early as 1784, sharp-eyed engineers and scientists noted striking similarities between the dynamics of seagoing vessels and aerial vehicles. By the early twentieth century, naval engineers and scientists were developing and designing airplanes and dirigibles using empirical principles derived from naval architecture. Several key researchers in aerodynamics began their career as naval architects (David A. Taylor, William F. Durand and Jerome C. Hunsaker) and carried out their experiments in ship testing facilities. By the 1930s, however, the transfer of knowledge (...) was irrevocably reversed as empiricism gave way to more fundamental, physics-based research. The rapid evolution of complex aircraft systems and flight envelopes led to new theoretical developments in aerodynamics and maneuvering, which quickly found their way into naval ship design. The theoretical and experimental results for airfoils, rigid airships and fixed-wing aircraft developed by Ludwig Prandtl, Theodore von Kármán, Max M. Munk and Hilda M. Lyon were employed in the hydrodynamic development of surface ships and submarines. This paper examines how the ideas, concepts and data from one discipline influenced the other and explores the processes by which that knowledge was transferred between disciplines. (shrink)

Engineering is often said to be ‘scientific’, but the nature of knowledge in engineering is different to science. Engineering has a different ontological basis—its theories address different entities and are judged by different criteria. In this paper I use Popper’s three worlds ontological framework to propose a model of engineering theories, and provide an abstract logical view of engineering theories analogous to the deductive-nomological view of scientific theories. These models frame three key elements from definitions of engineering: requirements, designs of (...) artefacts, and theories for reasoning about how artefacts will meet requirements. In a subsequent paper I use this ontological basis to explore methodological issues in the growth of engineering knowledge from the perspective of critical rationalism. (shrink)

Nasz problem z budynkami to dokładne przeciwieństwo problemu, z którym zmagał się Etienne Jules Marey, przeprowadzając swoje słynne badanie fizjologii ruchu. Przy pomocy wynalezionego przez siebie „fotorewolweru” chciał on uchwycić lot mewy w taki sposób, żeby móc zobaczyć każdą stopklatkę płynnego ruchu, którego mechanizm wymykał się obserwatorom aż do momentu pojawienia się tego właśnie wynalazku. My potrzebujemy czegoś przeciwnego, problem z budynkami polega bowiem na tym, że wydają się one dramatycznie statyczne. Uchwycenie ich jako ruchu, lotu czy serii przemian wydaje (...) się prawie niemożliwe. Wszyscy – zwłaszcza architekci – wiedzą, że budynek nie jest statycznym obiektem, ale raczej dynamicznym projektem. Nawet kiedy zostanie już wybudowany, każdy budynek zaczyna się starzeć, jest przekształcany przez użytkowników, a także modyfikowany przez wszystko, co wydarza się na zewnątrz i wewnątrz. Przeminie on lub zostanie odnowiony przy użyciu nowych materiałów, często zmieniony nie do poznania. Wiemy to wszystko, lecz problemem pozostaje to, że nie dysponujemy odpowiednikiem fotorewolweru Marey’a: kiedy myślimy o budynku, jest on zawsze nieruchomą, obojętną strukturą, przedstawianą w barwach procesowych2 na błyszczących stronach czasopism, przerzucanych przez klientów siedzących w poczekalniach biur projektowych. Skoro niemożność sfotografowania lotu mewy jako serii następujących po sobie stopklatek tak bardzo frustrowała Marey’a, jakże irytująca musi być dla nas niemożność zobrazowania płynności i ciągłego ruchu konstytuującego każdy budynek. W oparciu o dostępne mu dane wzrokowe Marey mógł ustalić fizjologię lotu dopiero po wynalezieniu sztucznego urządzenia. My również potrzebujemy narzędzia, abyśmy mogli przemienić statyczny obraz budynku w serię następujących po sobie stopklatek, które ostatecznie pokażą, że każdy budynek to tak naprawdę dynamiczny projekt.

Understanding nature of science is widely considered an important educational objective and views of NOS are closely linked to science teaching and learning. Thus there is a lively discussion about what understanding NOS means and how it is reached. As a result of analyses in educational, philosophical, sociological and historical research, a worldwide consensus about the content of NOS teaching is said to be reached. This consensus content is listed as a general statement of science, which students are supposed to (...) understand during their education. Unfortunately, decades of research has demonstrated that teachers and students alike do not possess an appropriate understanding of NOS, at least as far as it is defined at the general level. One reason for such failure might be that formal statements about the NOS and scientific knowledge can really be understood after having been contextualized in the actual cases. Typically NOS is studied as contextualized in the reconstructed historical case stories. When the objective is to educate scientifically and technologically literate citizens, as well as scientists of the near future, studying NOS in the contexts of contemporary science is encouraged. Such contextualizations call for revision of the characterization of NOS and the goals of teaching about NOS. As a consequence, this article gives two examples for studying NOS in the contexts of scientific practices with practicing scientists: an interview study with nanomodellers considering NOS in the context of their actual practices and a course on nature of scientific modelling for science teachers employing the same interview method as a studying method. Such scrutinization opens rarely discussed areas and viewpoints to NOS as well as aspects that practising scientists consider as important. (shrink)

The authors explore whether the need for ethical reflection on the part of designing engineers is dependent on the type of design process. They use Vincenti's distinction between normal and radical design and different levels of design hierarchy. These two dimensions are coupled with the concept of ill-structured problems, which are problems in which possible solutions cannot be ordered on a scale from better to worse. Design problems are better structured at lower hierarchical levels and in cases of normal design. (...) Better structured design problems require less ethical reflection on the part of designing engineers if such situations are characterized by the existence of generally accepted normative frameworks. Engineers could then deal with moral problems within the bounds of such frameworks and without the need for further reflection. On the basis of a number of empirical cases, the authors explore whether these ideas hold water. They discuss four cases ranging from a high-level radical design process to a low-level normal design process. (shrink)

Engineering deals with different problem situations than science, and theories in engineering are different to theories in science. So, the growth of knowledge in engineering is also different to that in science. Nonetheless, methodological issues in engineering epistemology can be explored by adapting frameworks already established in the philosophy of science. In this paper I use critical rationalism and Popper’s three worlds framework to investigate error elimination and the growth of knowledge in engineering. I discuss engineering failure arising from the (...) falsification of engineering theories, and present taxonomies of the sources of falsification and responses to falsification in engineering. From this I discuss contexts of research and design in engineering, ad hoc rescue of engineering theories, and engineering assurance. (shrink)

A recurrent theme in the characterization of synthetic biology is the role of engineering. This theme is widespread in the accounts of scholars studying this field and the biologists working in it, in those of the biologists themselves, as well as in policy documents. The aim of this article is to open this black-box of engineering that is supposed to influence and change contemporary life sciences. Too often, both synthetic biologists and their critics assume a very narrow understanding of what (...) engineering is about, resulting in an unfruitful debate about whether synthetic biology possesses genuine engineering methodologies or not. By looking in more detail to the diversity of engineering conceptions in debates concerning synthetic biology, a richer perspective can be developed. In this article, I will examine five influential ways in which engineering is understood in these debates, namely engineering as applied science, as rational methodology, context-sensitive practice, cunning activity or design. The claim is first of all thus to argue that engineering must not be seen as something stable or characterized by a fixed essence. It rather has multiple meanings and interpretations. Secondly, the claim is that most of the debates on synthetic biology cannot be indifferent towards the question which conception of engineering is at play, since the specific questions and concerns that pop up depend to a great extent on the precise conception of engineering one has in account. Many of the existing debates around synthetic biology can thus be reinterpreted and readdressed once one is aware of which conception of engineering is at play. (shrink)

While the issue of standards has received attention from analysts in science and technology studies, this attention has tended to focus on either units of measurement or compatibility standards. Much less attention has been devoted to equally important standards of practice. These are the procedural or process standards which govern how technologists go about designing and constructing artifacts. Such standards have a substantial documented history in the form of engineering codes of practice. As the embodiment of judgments rendered by a (...) particular community of technological practi tioners, these standards both reflect and shape the exercise of practitioner judgment. This article explores both these functions through examples drawn from structural and software engineering. These examples yield insights regarding both the role of formal procedural standards in technological practice and the unusual nature of software technology. (shrink)

Synthetic biology, an emerging field of science and technology, intends to make of the natural world a substrate for engineering practice. Drawing inspiration from conventional engineering disciplines, practitioners of synthetic biology hope to make biological systems standardized, calculable, modular, and predictably functional. This essay develops a Heideggerian reading of synthetic biology as a useful perspective with which to identify and explore key facets of this field, its knowledge, its practices, and its products. After overviews of synthetic biology and Heidegger’s account (...) of technology, I discuss calculability, utility, function, setting-upon, and ordering, with the aim of discussing the manner in which synthetic biology works to render the biological world intelligible as something to be used, rather than something that is in and of itself. Having developed this Heideggerian reading, I proffer a number of corrections to his account that enable a more accurate, nuanced understanding of synthetic biology. Specifically, I discuss the notion of Ge-stell and submit that multiple systems of “enframing” may help to make Heidegger’s argument more robust. I suggest that synthetic biology may work to reveal the natural world as a standing-reserve of function. (shrink)

Technologies have always been bearers of profound changes in science, society, and any other aspect of life. The latest technological revolution—the digital revolution—is no exception in this respect. This paper presents the revolution brought about by digital technologies through the lenses of a specific approach: the philosophy of information. It is argued that the adoption of an informational approach helps avoiding utopian or dystopian approaches to technology, both expressions of technological determinism. Such an approach provides a conceptual framework able to (...) address the ethical challenges that digital technologies pose, without getting stuck in the dichotomous thinking of technological determinism, and to bring together ethics, ontology, and epistemology into a coherent account.

The English language has adopted the word Tardis for something that looks simple from the outside but is much more complicated when inspected from the inside. The word comes from a BBC science fiction series, in which the Tardis is a machine for traveling in time and space, that looks like a phone booth from the outside. This paper claims that simulation models are a Tardis in a way that calls into question their transferability. The argument is developed taking Molecular (...) Modeling and Simulation as an example. There, simulation models are force fields that describe the molecular interactions and that look like simple and highly modular mathematical expressions. To make them work, they contain parameters that are adjusted to match certain data. The role of these parameters and the way they are obtained is seriously under-appreciated. It is constitutive for the model and central for its applicability and performance. Hence, the model is more than it seems so that working with adjustable parameters deeply affects the ontology of simulation models. This is particularly crucial for the transferability of the models: the information on how a model was trained is like luggage the model must carry on its voyage. (shrink)

This article reviews empirical and conceptual material from two distinct research traditions: on the science-technology relation and on industrial innovation. It aims both to shed new light on an old debate—the distinction between scientific and technological knowledge—and to refine our conceptualizations of the knowledge used by companies in the course of research and development leading to innovation. On the basis of three empirical studies, a composite categorization of different types of knowledge used in innovation is proposed, as part of a (...) broader framework encompassing two further taxonomic dimensions. It is hoped that this typology and framework might provide useful research tools in furthering our understanding of the knowledge transfers and transformations that occur in the course of innovation. It could also prove useful for organizations and groups facing difficult strategic choices about technology. (shrink)

Four hundred seventy-six nuclear power plants are in operation or under construction around the world. Are concepts for designing and operating plants safely sufficient? Conventional approaches are premised on expectations of predictability and control of radiation release and on assumptions that plant operations are closed systems. Field observations in the industry find, however, that the periodic necessity to refuel, test safety equipment, and continuously upgrade plant designs introduces challenges to control not originally calculated. The social and cultural contexts of markets, (...) regulation, and work systems create additional contingencies. In this dynamic environment, reactor operations produce invaluable data about the states of the entire technology and organizational system. Rereading these dynamics as "experiments" suggests an alternative epistemol ogy that synthesizes science's values of doubt, discovery, and documentation with engineering's values of efficiency, optimization, and problem solving. This redefines plant-based risk handlers as ethologists, geologists, and anthropologists of an ecology of visible and invisible hazards. (shrink)

This essay presents a long, detailed, in many ways critical but also appreciative account, of David Bloor’s recent book The Enigma of the Aerofoil. I take that work as the crowning statement of ideas and principles developed over the past four decades by Bloor and other exponents of the ‘strong programme’ in the sociology of scientific knowledge. It therefore offers both a test-case of that approach and a welcome opportunity to review, clarify and extend some of the arguments brought against (...) it by critical realists. This purpose is particularly well served by Bloor’s having here assembled such a wealth of scientific, historical, political and socio-cultural data concerning one specific, very crucial period of research into theories of aerodynamic lift. His book thus provides an exceptionally useful point of engagement for anyone seeking to adjudicate these issues from a critically angled but engaged and constructive standpoint. (shrink)

Background The subject of technology looks different depending on context. There is also an epistemological complexity to technological knowledge in technology education. Purpose To gain a deeper understanding of the epistemological foundations of the subject of technology and technology teaching, the teachers views are needed. The aim of this study is to examine how teachers discuss technology education, with a particular focus on how they talk about technological knowledge. Sample 19 Technology teachers from compulsory school in Sweden participated. Design and (...) methods Through focus groups, teachers views of knowledge in technology education were collected and then analysed. Results The results consist of three parts. Firstly, it was found that the teachers were unfamiliar with discussing epistemology in technology education. Secondly, interpreting their views of knowledge in technology education through a theoretical framework for knowledge in technology education yielded examples of knowledge from the three constituent categories: technical skills, technological scientific knowledge, and socio-ethical technical understanding. Finally, an inductive analysis revealed two categories based on the teachers broader views of knowledge: civic capabilities and engineering capabilities. Conclusion Overall, the results provide an understanding of teachers ways of describing technological knowledge. The teachers perceived the term knowledge in a broader way than traditional epistemology, including capabilities in their descriptions. We propose a new perspective on the character of knowledge and capability in technology education, called technology education competence. The results of this study point to important aspects of the nature of the subject, which might lead to reflection about what knowledge should be considered of value in the future regarding research but especially development of curricula.

This inclusive cross-cultural study rethinks the nexus between engineering education and context. In so doing the book offers a reflection on contextual boundaries with an overall boundary crossing ambition and juxtaposes important cases of critical participation within engineering education with sophisticated scholarly reflection on both opportunities and discontents. -/- Whether and in what way engineering education is or ought to be contextualized or de-contextualized is an object of heated debate among engineering educators. The uniqueness of this study is that this (...) debate is given comprehensive coverage – presenting both instrumentally inclined as well as radical positions on transforming engineering education. -/- In contextualizing engineering education, this book offers diverse commentary from a range of disciplinary, meta- and interdisciplinary perspectives on how cultural, professional, institutional and educational systems contexts shape histories, structural dynamics, ideologies and challenges as well as new pathways in engineering education. Topics addressed include examining engineering education in countries ranging from India to America, to racial and gender equity in engineering education and incorporating social awareness into the area. -/- Using context as “bridge” this book confronts engineering education head on. Contending engineering ideologies and corresponding views on context are juxtaposed with contending discourses of reform. The uniqueness of the book is that it brings together scholars from the humanities, the social sciences and engineering from Europe – both East and West – with the United States, China, Brazil, India and Australia.

The article reevaluates the reception of Mendelism in France, and more generally considers the complex relationship between Mendelism and plant breeding in the first half on the 20th century. It shows on the one side that agricultural research and higher education institutions have played a key role in the development and institutionalization of genetics in France, whereas university biologists remained reluctant to accept this approach on heredity. But on the other side, plant breeders, and agricultural researchers, despite an interest in (...) Mendelism, never came to see it as the breeders' panacea, and regarded it instead as of only limited value for plant breeding. I account for this judgment in showing that the plant breeders and Mendelism designed two contrasting kinds of experimental systems and inhabited distinct experimental cultures. While Mendelian geneticists designed experimental systems that allowed the production of definite ratios of different forms that varied in relation to a few characters, plant breeders' experimental systems produced a wide range of variation, featuring combinations between hundreds of traits. Rather than breaking this multiple variation down into simple elements, breeders designed and monitored a genetic lottery. The gene was a unit in a Mendelian experimental culture, an "epistemic thing" as Rheinberger put it, that could be grasped by means of statistical regularities, but it remained of secondary importance for French plant breeders, for whom the strain or the variety -- not the gene -- was the fundamental unit of analysis and manipulation.

The direct reading emission spectrometer was developed during the1940s. By substituting photo-multiplier tubes and electronics forphotographic film spectrograms, the interpretation of special lineswith a densitometer was avoided. Instead, the instrument providedthe desired information concerning percentage concentration ofelements of interest directly on a dial. Such instruments `de-skill' the job of making such measurements. They do this by encapsulatingin the instrument the skills previously employed by the analyst,by `skilling' the instrument. This paper presents a history of thedevelopment of the Dow Chemical/Baird Associates (...) direct reader. Thishistory is used to argue for a materialist conception of knowledge.The instrument is a material form of knowledge, knowledge of aspectsof spectroscopy, analytical spectrochemistry, electronics, instrumentdesign and construction, and metal production industry economics.

My brand of evolutionary economics recognizes, highlights, that modern economies are always in the process of changing, never fully at rest, with much of the energy coming from innovation. This perspective obviously draws a lot from Schumpeter. Continuing innovation, and the creative destruction that innovation engenders, is driving the system. There are winners and losers in the process, but generally the changes can be regarded as progress. The processes through which economic activity and performance evolve has a lot in common (...) with evolution in biology. In particular, at any time the economy is marked by considerable variety, there are selection forces winnowing on that variety, but also continuing emergence of new ways of doing things and often economic actors. But there also are important differences from biological evolution. In particular, both innovation and selection are to a considerable degree purposive activities, often undertaken on the basis of relatively strong knowledge. (shrink)

Public “upstream engagement” and other approaches to the social control of technology are currently receiving international attention in policy discourses around emerging technologies such as nanotechnology. To the extent that such approaches hold implications for research and development (R&D) activities, the distinct participation of scientists and engineers is required. The capacity of technoscientists to broaden the influences on R&D activities, however, implies that they conduct R&D differently. This article discusses the possibility for more reflexive participation by scientists and engineers in (...) the internal governance of technology development. It reviews various historical attempts to govern technoscience and introduces the concept of midstream modulation, through which scientists and engineers, ideally in concert with others, bring societal considerations to bear on their work.

: Though many are agreed that "technoscience" is a significant phenomenon, little systematic attention has yet been paid to the circumstances under which it has emerged. Technoscience is conceptualized here as the outcome of a process of convergence in which technological knowledge acquires many of the characteristics of scientific knowledge while the latter shifts in the opposite direction. The analytical problem is then a matter of understanding why such "drift" has occurred at particular times and places. The drift of higher (...) technical education toward science has been observed in a variety of domains including engineering and medicine, but in this paper I identify such a trend in late nineteenth and early twentieth century agricultural education, with particular reference to Bavaria. The process is interpreted using a model of institutional dynamics loosely based upon Bourdieu's concept of the academic "field.". (shrink)

La concepción de la tecnología como ciencia aplicada constituyó, desde mediados del siglo XX, la visión hegemónica respecto a la cuestión del conocimiento tecnológico. Si bien, a partir de la década de 1970, han surgido propuestas alternativas a este planteamiento más clásico, aún no se ha estudiado con suficiente profundidad la naturaleza del conocimiento requerido para diseñar y producir bioartefactos. Este artículo trata el problema del conocimiento tecnológico con el objetivo de proponer una caracterización epistemológica general de la biotecnología. Los (...) resultados muestran que el conocimiento biotecnológico está constituido por diferentes tipos de conocimiento que incorporan, por una parte, un contenido prescriptivo y, en alguna medida, tácito y, por otra, un conocimiento representacional que no viene necesariamente proporcionado por la investigación de las ciencias naturales. Se concluye que el análisis del conocimiento prescriptivo de la biotecnología que no se limita a un conjunto de reglas tecnológicas, su carácter tácito fundamental en contextos de innovación en el diseño y el conocimiento representacional que pueda proceder de la investigación de los propios biotecnólogos hace posible una caracterización de la naturaleza del conocimiento biotecnológico que sobrepasa la concepción estándar de la tecnología como ciencia aplicada.
