Peu de travaux explorent les liens grands-parents/petits-enfants en contexte homoparental. Ces travaux montrent une attitude différenciée des grands-parents selon l’acceptation ou non de l’homosexualité de leur enfant devenu parent et un engagement spécifique selon la lignée et/ou le statut légal de parent. La recherche sur laquelle s’appuie cet article porte sur une vingtaine de couples lesboparentaux français (questionnaires et entretiens) avec des enfants nés en 2011 ou 2012, mariés ou non depuis, qui se différencient selon le type de maternité mis (...) en œuvre et le statut du donneur. Les résultats mettent en évidence que plus le couple lesbien se rapproche du modèle bioconjugal, ou plus exactement du modèle conjugo-parental, plus les relations entre petits-enfants et grands-parents sont facilitées des deux côtés des branches maternelles et ceci selon les enjeux intergénérationnels et relationnels de la transmission.

Models as Mediators discusses the ways in which models function in modern science, particularly in the fields of physics and economics. Models play a variety of roles in the sciences: they are used in the development, exploration and application of theories and in measurement methods. They also provide instruments for using scientific concepts and principles to intervene in the world. The editors provide a framework which covers the construction and function of scientific models, and explore the ways in which they (...) enable us to learn about both theories and the world. The contributors to the volume offer their own individual theoretical perspectives to cover a wide range of examples of modelling, from physics, economics and chemistry. These papers provide ideal case-study material for understanding both the concepts and typical elements of modelling, using analytical approaches from the philosophy and history of science. (shrink)

During the last two centuries, the way economic science is done has changed radically: it has become a social science based on mathematical models in place of words. This book describes and analyses that change - both historically and philosophically - using a series of case studies to illuminate the nature and the implications of these changes. It is not a technical book; it is written for the intelligent person who wants to understand how economics works from the inside out. (...) This book will be of interest to economists and science studies scholars. But it also aims at a wider readership in the public intellectual sphere, building on the current interest in all things economic and on the recent failure of the so-called economic model, which has shaped our beliefs and the world we live in.

The inner ache: an experiential perspective on IonelinessThis paper examines the various theoretical approaches that have informed both the conceptualizations and the research approaches to investigations of loneliness. A focus on phenomenological and existential perspectives of loneliness can assist in an understanding of what is essentially a subjective distressing experience. The elderly, particularly those residing in nursing homes, are vulnerable to feelings of existential loneliness because following busy lives, often they are left without meaningful roles. Concomitant to this sense of (...) loss of meaning is an alteration in the perception of lived time. It is the purpose of this paper to stimulate research into what is a common but profoundly distressing experience. (shrink)

This article explores the characteristics of research sites that scientists have called “natural experiments” to understand and develop usable distinctions for the social sciences between “Nature’s or Society’s experiments” and “natural experiments.” In this analysis, natural experiments emerge as the retro-fitting by social scientists of events that have happened in the social world into the traditional forms of field or randomized trial experiments. By contrast, “Society’s experiments” figure as events in the world that happen in circumstances that are already sufficiently (...) “controlled” to be open for direct analysis without reconstruction work.

This paper addresses the problem of how scientific knowledge, which is always locally generated, becomes accepted in other sites. The analysis suggests that there are a small number of strategies that enable scientists to resituate knowledge and that these strategies are generic: they are not restricted to specific disciplines or modes of doing science but rather are found in a variety of different forms across the sciences.

Critiques of case studies as an epistemic genre usually focus on the domain of justification and hinge on comparisons with statistics and laboratory experiments. In this domain, case studies can be defended by the notion of “infirming”: they use many different bits of evidence, each of which may independently “infirm” the account. Yet their efficacy may be more powerful in the domain of discovery, in which these same different bits of evi- dence must be fully integrated to create an explanatory (...) account with internal validity.

The provocative paper by John Forrester ‘If p, Then What? Thinking in Cases’ opened up the question of case thinking as a separate mode of reasoning in the sciences. Case-based reasoning is certainly endemic across a number of sciences, but it has looked different according to where it has been found. This article investigates this mode of science – namely thinking in cases – by questioning the different interpretations of ‘If p?’ and exploring the different interpretative responses of what follows (...) in ‘Then What?’. The aim is to characterize how ‘reasoning in, within, with, and from cases’ forms a mode of scientific investigation for single cases, for runs of cases, and for comparative cases, drawing on materials from a range of different fields in which case-based reasoning appears.

It has long been thought that observing distinctive traces of quantum gravity in a laboratory setting is effectively impossible, since gravity is so much weaker than all the other familiar forces in particle physics. But the quantum gravity phenomenology community today seeks to do the (effectively) impossible, using a challenging novel class of `tabletop' Gravitationally Induced Entanglement (GIE) experiments, surveyed here. The hypothesized outcomes of the GIE experiments are claimed by some (but disputed by others) to provide a `witness' of (...) the underlying quantum nature of gravity in the non-relativistic limit, using superpositions of Planck-mass bodies. We inspect what sort of achievement it would possibly be to perform GIE experiments, as proposed, ultimately arguing that the positive claim of witness is equivocal. Despite various sweeping arguments to the contrary in the vicinity of quantum information theory or given low-energy quantum gravity, whether or not one can claim to witness the quantum nature of the gravitational field in these experiments decisively depends on which out of two legitimate modelling paradigms one finds oneself in. However, by situating GIE experiments in a tradition of existing experiments aimed at making gravity interestingly quantum in the laboratory, we argue that, independently of witnessing or paradigms, there are powerful reasons to perform the experiments, and that their successful undertaking would indeed be a major advance in physics.

A long-standing tradition presents economic activity in terms of the flow of fluids. This metaphor lies behind a small but influential practice of hydraulic modelling in economics. Yet turning the metaphor into a three-dimensional hydraulic model of the economic system entails making numerous and detailed commitments about the analogy between hydraulics and the economy. The most famous 3-D model in economics is probably the Phillips machine, the central object of this paper.

Philosophers of science studying scientific practice often consider it a methodological requirement that their conceptualization of "model" closely connects with the understanding and use of models by practicing scientists. Occasionally, this connection has been explicitly made (Hutten 1954, Suppes 1961, Morgan and Morrison 1999, Bailer-Jones 2002, Lehtinen and Kuorikoski 2007, Kuorikoski 2007, Morgan 2012a). These studies have been dominated by a focus on the—relatively similar forms of—mathematical models in physics and economics. Yet it has become increasingly evident that the way (...) models are conceptualized is very different in some other sciences, where philosophers' accounts of models' characteristics and .. (shrink)

Modelling became one of the primary tools of mathematical economic research in the twentieth century, but when we look at examples of how nonanalogical models were first built in economics, both the process of making representations and aspects of the representing relation remain opaque. Like early astronomers, economists have to imagine how the hidden parts of their world are arranged and to make images, that is, create models, to represent how they work. The case of the Edgeworth Box, a model (...) widely used for theoretical work in twentieth-century economics, provides a good example to explore the process of making mathematical representations of the economy. It shows how, in making these new representations, conceptual elements were developed which could not have been represented in the older verbal forms of economics. (shrink)

The traditional Christian teaching is that engaging in sexual activity, whether heterosexual or homosexual, outside the marriage of one man and one woman is sinful. In direct contrast, there are those in the Church who quite recently have begun to insist that the traditional teachings concerning sexual sin need to be changed. In particular, the effort is being made to have the Church accept homosexual behavior as not sinful or problematic in any way—at least not for committed homosexuals, as comparable (...) to committed heterosexuals in a marriage. As we all know, this relatively recent view has been promoted heavily in the media and popular culture, and even by our national government. As we make our observations, we will particularly focus on traditional Orthodox Christianity as the fullness of the truth and, thus, the source of the true alternative to this “new” outlook that is gripping much of popular Western culture today.

Mary Hesse's well-known work on models and analogies gives models a creative role to play in science, which rests on developing certain analogical properties considered neutral between the two fields. Case study material from Irving Fisher's work (The Purchasing Power of Money, 1911), in which he used analogies to construct models of monetary relations and the monetary system, highlights certain omissions in Hesse's account. The analysis points to the importance of taking account of the negative properties in the analogies (...) and to certain differences between "ready-made" analogies (models of systems based on existing analogical structures) and "designed" analogies (models built up from separate analogical features).

What is the nature of reality? What does it mean to be human? And how do we account for ethics and morality? Mary Poplin examines naturalism, humanism, pantheism and Judeo-Christian theism and explores the fundamental assumptions and limitations of each perspective.

Over the last 40 years or so, economics has become a modelling science: a science in which models have become one of the main epistemological tools both for theoretical and applied work. But providing an account of how models work and what they do for the economist is not easy. For the philosopher of economics like me, struggling with this question, John Sutton's views on the nature and design of economic models and how they work is indeed thought provoking. Because (...) of my own interests, my review of Sutton's book: Marshall's Tendencies: What Can Economists Know? will focus on three related issues that I found especially intriguing in his treatment of the role of models in modern economics. The first is the way that Sutton's account fits with my own reading of the history of twentieth-century economics, namely that the focus of economic explanation has moved during the last century from and to and . The second is to understand the epistemological connotations of Sutton's view. The third is to explore what Sutton means when he says a model . These three questions roughly coincide with the material presented in Chapters 1, 3 and 2 respectively of the book. As we shall see, Sutton gives us a practitioner account of applied economics which can fit within the standard terms used by philosophers of economics on theory-testing, but which reveals a number of novel elements for philosophical analysis.

While historians of nineteenth‐century German philosophy have traditionally underestimated the influence of Schopenhauer's thought, recent scholarship has demonstrated that Schopenhauer's pessimism changed the trajectory of German philosophy. This chapter summarizes Schopenhauer's philosophical system to underscore that his doctrine of pessimism cannot be confined to his ethics, but rather informs every aspect of his philosophy. The thrust is to summarize Schopenhauer's philosophy while highlighting the pessimistic strains, both implicit and explicit, that run through his thought. The chapter first describes pessimism, drawing (...) both from Schopenhauer scholarship. Then, it provides an outline of Schopenhauer's system, pointing to the pessimistic consequences of various aspects of his system. The chapter highlights the pessimistic features that run through Schopenhauer's system; features which apply to both Migotti's and Deinstag's depictions of what pessimism entails. Schopenhauer has provided a comprehensive account of his philosophical system in his major work, The World as Will and Representation volumes I and II. (shrink)

Deidealization as a topic in its own right has attracted remarkably little philosophical interest despite the extensive literature on idealization. One reason for this is the often implicit assumption that idealization and deidealization are, potentially at least, reversible processes. We question this assumption by analyzing the challenges of deidealization within a menu of four broad categories: deidealizing as recomposing, deidealizing as reformulating, deidealizing as concretizing, and deidealizing as situating. On closer inspection, models turn out much more inflexible than the reversal (...) thesis would have us believe, and deidealization emerges as a creative part of modeling. (shrink)

Graeme Earl's paper on computer graphic modeling in archaeology raises many themes of interest for the philosopher of science, although, as is to be expected of complex social and technical disciplinary practices, these philosophical issues are not to be easily separated or neatly labeled. On the one hand, the modeling practices and concerns of the archaeologists dispute (or even disrupt) the philosophers' traditional notions, while the formers' reective commentaries offer sophisticated analyses that go beyond the latters' traditional reflections on models. (...) On the other hand, the paper raises new questions about how human and social scientists—as humans with social lives—engage with models in their different .. (shrink)

Narrative Science examines the use of narrative in scientific research over the last two centuries. It brings together an international group of scholars who have engaged in intense collaboration to find and develop crucial cases of narrative in science. Motivated and coordinated by the Narrative Science project, funded by the European Research Council, this volume offers integrated and insightful essays examining cases that run the gamut from geology to psychology, chemistry, physics, botany, mathematics, epidemiology, and biological engineering. Taking in shipwrecks, (...) human evolution, military intelligence, and mass extinctions, this landmark study revises our understanding of what science is, and the roles of narrative in scientists' work.
