This paper combines the use of gift theory and the metatheory of the Morphogenetic Approach as a framework for the proposal that the relationship between unpaid interns and ‘employers’ may be conceptualized as a form of transactional, but asymmetrical, gift-exchange. The article begins by applying insights from gift theory to the findings of a range of studies into unpaid internships. It is argued that, while interns are the initial gift-givers in delivering unpaid labour, ‘employers’ often demonstrate weak reciprocation in (...) terms of offering paid work. Following that, the article combines gift analysis with the Morphogenetic Approach. This framework offers ontological depth to the substantive propositions of gift theory, and provides conceptual tools to study the interplay between structure/culture and agency that form the intern-‘employer’ relationship. The contribution of this article lies in the combined use of two key theoretical perspectives to a problematic not previously examined through such concepts. (shrink)

Resumen: Margaret Archer elabora una propuesta para el análisis de la cultura, conocida como enfoque morfogenético, cuyo eje corre paralelo al debate clásico dentro de la teoría social sobre la relación estructura-agencia. La perspectiva de Archer se configura a partir de lo que llama dualismo analítico, el cual se presenta como una alternativa a las posturas reduccionistas que enfatizan una sola dimensión, pero también se diferencia de la postura integracionista subyacente en la teoría de la estructuración. Para elucidar el enfoque (...) morfogenético se explicitan los postulados del realismo crítico, con cuyos fundamentos ontológicos y epistemológicos se vincula. La contribución realizada por Archer resulta ser un referente obligado para el abordaje y explicación de la dinámica cultural en tanto que, permite identificar elementos a partir de los cuales explicar por qué algunas contradicciones producen cambios y otras no lo hacen.: Margaret Archer has elaborated a proposal for the analysis of culture, known as morphogenetic approach, whose axis runs parallel to the classical debate within the social theory on the structure-agency relation. Archer's perspective is shaped by what she calls analytic dualism, which is presented as an alternative to the reductionist stances that emphasize a single dimension, but her perspective also differs from the underlying integrationist stance in the theory of structuring. To elucidate the morphogenetic approach, the postulates of critical realism are explained, with the ontological and epistemological foundations of which it is linked. The contribution made by Archer proves to be a necessary reference for the approach and explanation of the cultural dynamics because it allows to identify elements to explain why some contradictions produce changes and others do not.

With its emphasis on analytical dualism and its detailed account of the concepts and methods necessary for its application, Margaret Archer's morphogenetic approach seems to provide significant potential for empirical research. Over a decade after its publication, however, the potential of the approach remains largely unrealised. This paper seeks to begin to address this situation by reporting on and assessing the application of the morphogenetic approach to a longitudinal case study of information systems development and organisational change in (...) British local government. This assessment confirms Archer's claims for the approach's value as an instrument for the production of non-conflationary practical social theory. In addition, certain features of the methodology moved the analysis of IS and organisational change beyond that of more mainstream approaches used for this type of research. However, a range of issues are identified which demonstrate that the complexity and resulting resource intensity of the approach may well work against its more widespread adoption for empirical research.

The concept of self-organizing potential proposed by Atlan, conceived within the framework of information theory', attempts to explain the emergence of the structures and functions of the organism, as well as the concept of morphogenetic potential, conceived in the embryological laboratories. Are the two theses diverging or converging and/or complementary to each other?The paper indicates, first, the context of Atlan's thesis and the meaning of his concepts of self-organization and self-organizing potential in evolutionary systems as well as in individual (...) systems. It then develops an in-depth analysis of these individual systems and attempts to discern, in Atlan's thesis, the respective roles of the genetic factors and of the epigenetic factors in the formation of the individual, particularly during morphogenesis. This analysis reveals some difficulties inherent in the theory and induces the author to propose a few additional distinctions.Finally, the paper underlines the analogies and divergences between the concepts of self-organizing potential and morphogenetic potential.La notion de potentiel auto-organisateur proposée par H. Atlan et née dans le cadre de la théorie de l'information, veut, tout autant que la notion de potentiel morphogénétique, née dans les laboratories des embryologistes, expliquer l'émergence des structures et des functions de l'organisme. Les deux thèses sont-elles divergentes ou convergentes et/ou complémentaires?L'article précise d'abord le contexte de la thèse d'Atlan et la signification de ses notions d'auto-organisation et de potentiel auto-organisateur relatives aussi bien aux systèmes évolutifs qu'aux systèmes individuels. Il s'attarde par la suite à l'analyse de ces systèmes individuels et veut cerner quels sont, d'après la thèse d'Atlan, les rôles respectivs du génétique et de l'épigénétique dans la formation de l'individu, tout particulièrement pendant la morphogenèse. Cette analyse révèle certaines difficultés de la théorie et conduit l'auteur à suggérer quelques distinctions additionnelles.L'article souligne ensuite les analogies et les divergences entre les notions de potential auto-organisateur et de potential morphogénétique.

Evolutionary change is opportunistic, but its course is strongly constrained in several fundamental ways. These constraints (historical/phylogenetic, functional/adaptive, constructional/morphogenetic) and their dynamic relationships are discussed here and shown to constitute the conceptual framework of Constructional Morphology. Notwithstanding recent published opinions which claim that the discovery of constraints renders Neodarwinian selection theory obsolete, we regard the insights of Constructional Morphology as being entirely consistent with this theory. As is shown here in the case of the Hyracoidea, formal analysis of (...) the constraints which have framed the evolution of various characters extends our understanding of the evolution of a taxon.

Morphological EvoDevo is a field of biological inquiry in which explicit relations between evolutionary patterns and growth or morphogenetic processes are made. Historically, morphological EvoDevo results from the coming together of several traditions, notably Naturphilosophie, embryology, the study of heterochrony, and developmental constraints. A special feature binding different approaches to morphological EvoDevo is the use of formalisms and mathematical models. Here we will introduce anatomical network analysis, a new approach centered on connectivity patterns formed by anatomical parts, with (...) its own concepts and tools specifically designed for the study of morphological EvoDevo questions. Riedl’s concept of burden is tightly related to the use of anatomical networks, providing a nexus between the evolutionary patterns and the structural constraints that shape them. (shrink)

Genetic analysis of Drosophila has shown that a morphogenetic gradient of the Transforming Growth Factor‐β family member dpp patterns the embryonic dorsalventral axis. Molecular and embryological evidence from Xenopus has strongly suggested a similar role for Bmp‐4, the dpp homolog, in patterning the dorsalventral axis of chordates. A recent report has now identified mutations in two genes, dino and swirl, that disrupt dorsal‐ventral patterning in the zebrafish Danio rerio(1). Characterization of these mutations parallels findings from Drosophila, thus establishing (...) a genetic framework for the analysis of dorsalventral patterning in a vertebrate. (shrink)

Working within an Archerian morphogenetic framework, I suggest that we need to pay more attention to practices. Instead of the mainstream focus on practice as action, I argue that we should pay attention to practices as a key structural and cultural element of analysis. Practices cannot be simply read-off from beliefs, that is, they are not an inevitable practical counterpart to belief. Although belief is relevant, it does not provide the full explanation for the presence of practices. Therefore, (...) the same or similar beliefs can result in significantly different practices depending on factors such as advances in technology and changes in modes of dissemination of theological doctrine. To illustrate my argument, I consider historical work on comparative religious practices, specifically the distinction between rituals and routines. A focus on the latter, as the conditions of possibility for the former, leads to some implications for the thesis of the morphogenesis of contemporary society. An analysis of the relationship between religious rituals and routines stresses the importance of placing both in their wider cultural and structural context. (shrink)

The genetic analysis of development has revealed the importance of small sets of interacting genes in most morphogenetic processes. The results of gene interactions have so far been examined intuitively. This approach is largely sufficient when one deals with simple interactions, a feedback circuit for example. As more components become involved, however, it is difficult to make sure that the intuitive approach gives a comprehensive view of the behaviour of the system. In this paper, we illustrate the use (...) of a logical approach to describe the genetic circuit that underlies the singling out of sense organ precursor cells in Drosophila. We show how to apply logical modelling to a realistic problem, and how this approach allows an easy assessment of the dynamic properties of the system, i.e., of its possible evolutions and of its reactions to fluctuations and perturbations.

Platelet‐derived growth factor (PDGF) was originally identified in platelets and in serum as a mitogen for fibroblasts, smooth muscle cells (SMC) and glia cells in culture. PDGF has since expanded to a family of dimers of at least four gene products, whose biological actions are mediated through two receptor tyrosine kinases, PDGFRs. The present review summarizes and discusses the biological functions of PDGFs and PDGFRs in developmental processes, mainly as revealed through genetic analysis in mice. Such studies have demonstrated (...) multiple critical roles of PDGFs and PDGFRs in embryonic and postnatal development. PDGFs seem to act upon specific populations of progenitor cells that give rise to several different cell types with distinct functions in a variety of developmental processes. Analogies are seen between the cell functions and the developmental processes controlled by PDGFs. This suggests that ancestral PDGF and PDGFR expression patterns and functions may have been iterated in related sets of morphogenetic processes in the course of evolution.

Data from experiments on Erica × darleyensis and from related observations (Viémont and Beaujard, 1983) are taken for a critical analysis of the proposed model of morphogenetic phenomena. The criteria for judging the coherence of the constructions proposed in plant morphology are based on mathematical constructions deduced from Petri nets, especially elementary nets.

This essay pushes the history of a scientific discipline, morphology, toward a broader philosophically informed and cross-disciplinarily engaged history of knowledge. It shows that by looking at how knowledge and practices circulated between scientific disciplines (such as biology) and technoscientific ones (like architecture and design) we can better understand how (morphological) knowledge was produced. By doing so, the analysis contributes to the study of the mechanisms of knowledge exchange between the organic and the technical worlds and, more broadly, to (...) the study of the dynamics of knowledge circulation. First, the essay analyzes the engineering studies of organic form conducted by the Austro-Hungarian botanist Raoul Heinrich Francé (1874–1943) and the Scottish polymath D’Arcy Wentworth Thompson (1860–1948). Subsequently, the essay moves to twenty-first-century morphogenesis. It examines the transfer of the notion of morphospace, a paleontological practice of data visualization, into biology-inspired architectural design. The conclusion deals with the broader features of knowledge transfer and circulation. Twentieth- and twenty-first-century morphologists successfully translate and transfer morphogenetic processes from nature into technical artifacts to achieve technical solutions to given problems. In the translation of organic morphogenesis into a technical process, evolution’s intrinsic historical contingency was deliberately left behind. (shrink)

This edited collection of papers seeks to celebrate the scope and accomplishment of Margaret Archer’s work, distilling her theoretical and empirical contributions into four sections, capturing the essence and trajectory of her work over almost four decades. Long fascinated with the problem of structure and agency, Archer’s work has constituted a decades long engagement with this perennial issue of social thought. Through an initial empirical study and two expansive trilogies, Archer has developed an explanatory framework that comes to grips with (...) the complexity of social processes at different levels of analysis over time. _The Morphogenetic Approach_ and, later, her work on the _Internal Conversation_, together, provide a detailed account of the interrelated processes by which structure, agency and culture come to take the forms they do. However in spite of the deep interconnections which unify her body of work, it is rarely treated as a coherent whole. Though its range and depth has been widely acknowledged, it nonetheless has an unclear place within the cannon of sociological theory. The proposed collection seeks to address this relative neglect through collating a selection of papers, spanning Archer’s career, which collectively elucidate both the development of her thought and the value which can be found in it as a systematic whole. It seeks to illustrate the empirical origins of her later ideas in her early work on the sociology of education, as well as foregrounding the diverse range of influences which have conditioned her intellectual trajectory: the systems theory of Walter Buckley, the functionalist Marxism of David Lockwood, the critical realist philosophy of Roy Bhaskar and, more recently, her engagement with American pragmatism and the Italian school of relational sociology.

Experimental evidence strongly supports the view that the subdivision of organ anlagen into smaller structural units is an autonomous process. Dalcq &Pasteels' hypothesis which says that the boundaries between the different areas into which a morphogenetic field differentiates are determined by “Threshold values” in the “potential” of the field in question, is inconsistent with our present knowledge of biochemical reaction systems. Threshold values may only be used indescribing the spatial differentiation of a morphogenetic field. It is suggested that (...) the latter concept be replaced by the concept of “optimal values” in the intensity of a morphogenetic field-specific for the various chemo-differentiations characterizing the different regions into which a morphogenetic field will split up-and that each optimal value isdeterminative for the appearance of one particular differentiation within the morphogenetic field, each differentiation being formed within a certain range of intensity of the field. On the basis of the hypothesis formulated above a “virginal” morphogenetic field will necessarily differentiate into a number of smaller fields of second order, which in their turn will split up into fields of third order, etc. ” Pattern formation” may be defined as the differentiation of a morphogenetic field into an increasing number of smaller fields of higher order of qualitative different chemical and structural composition. Since differentiation of a morphogenetic field proceeds autonomously, the capacity for pattern formation is an intrinsic property of a morphogenetic field. In the light of these considerations it is suggested that a morphogenetic field action is responsible for the first differentiation of the developing embryo into regions with predominantly ectodermal, mesodermal or endodermal differentiation tendencies. The present knowledge about the characteristic pattern formation taking place in the axial mesoderm as well as in the overlying neural plate seems to be in good agreement with the implications of the present morphogenetic field concept. It is emphasized, however, that if the present morphogenetic field concept cannot be characterized further biochemically and biophysically, it will have to be replaced by another concept which can be defined more sharply and is more easily accessible to experimental analysis. Les preuves expérimentales confirment que la subdivision des ébauches des organes en unités structurelles plus petites est un processus autonome. L'hypothèse deDalcq &Pasteels disant que les bornes entre les différents domaines formées par la différenciation d'un champ morphogénétique sont déterminées par des „valeurs seuil” dans le „potentiel” du champ en question, n'est pas en harmonie avec notre connaissance actuelle des systèmes biochimiques.

Ce seraient les valeurs spécifiques aux différenciations chimiques diverses qui caractérisent les différents domaines dans lesquels un champ morphogénétique se différencie. En outre, chaque valeur optimale serait déterminative à la formation d'une différenciation spéciale dans le champ morphogénétique, chaque différentiation se formant dans un certain trajet de l'intensité du champ. Par suite de l'hypothèse formulée ci-dessus un champ morphogénétique “virginal” va nécessairement se différencier en un nombre de champs plus petits de deuxième ordre, qui à leur tour se divisent en champs d'ordre troisième, etc. ... La régionalisation peut être définie comme la différenciation d'un champ morphogénétique dans un nombre de plus en plus élevé de champs plus petits d'ordre supérieur de composition chimique et structurelle qualitativement différente. Parce que la différenciation d'un champ morphogénétique se produit de façon autonome, le pouvoir de régionalisation est une propriété intrinsique d'un champ morphogénétique. Ces considérations nous mènent à proposer que l'action d'un champ morphogénétique est responsable de la première différenciation de l'embryon en régions qui possèdent des tendences de différenciation principalement ectodermiques, mésodermiques, ou bien endodermiques. La connaissance actuelle concernant la régionalisation caractéristique qui se produit dans le mésoderme axial ainsi que dans la plaque neurale superposée paraît se conformer aux conséquences du concept de champ morphogénétique. Cependant on souligne le fait que dans le cas òu le concept actuel du champ morphogénétique ne pourra pas être plus amplement caractérisé de façon biochimique et biophysique, il faudra le remplacer par un autre concept qui puit être défini plus nettement et qui est mieux accessible à l'analyse expérimentale. Die Auffassung, dass die Aufteilung von Organanlagen in kleineren Struktureinheiten ein selbständiger Prozess ist, findet Bestätigung in den experimentellen Ergebnissen. Die Hypothese vonDalcq &Pasteels , dass die Grenzen zwischen den unterschiedenen Gebieten, in denen ein morphogenetisches Feld sich differenziert, durch “Schwellenwerte” im “Potential” des genannten Feldes bestimmt werden, ist unvereinbar mit unserem heutigen Wissen über biochemischen Reaktionssystemen.

Statt dieses Begriffs wird der Begriff “Optimaler Wert” vorgeschlagen; Werte also in der Intensität eines morphogenetischen Feldes, optimal und spezifisch für die verschiedene Chemodifferenzierungen, welche die Gebiete kennzeichnen, in denen ein morphogenetisches Feld sich differenzieren wird. Jeder optimaler Wert soll dann das Erscheinen einer bestimmten Differenzierung innerhalb des morphogenetischen Feldes veranlassen, welche Differenzierung sich bildet innerhalb eines bestimmten Bereichs der Feldintensität. Auf Grund der obigen Hypothese wird ein “virginelles” morphogenetisches Feld zwangsläufig sich differenzieren in eine Anzahl kleinerer Feldern zweiten Grades; diese in Felder dritten Grades, usw. Musterbildung könnte definiert werden als die Differenzierung eines morphogenetischen Feldes in eine zunehmende Anzahl kleinerer Felder höheren Grades von qualitativ verschiedener chemischen und strukturellen Zusammensetzung, Weil diese Differenzierung autonom vor sich geht, ist das Vermögen zur Musterbildung eine innewohnende Eigenschaft eines morphogenetischen Feldes. Im Lichte dieser Betrachtungen ist es naheliegend anzunehmen dass eine morphogenetische Feldwirkung verantwortlich ist für die erste Differenzierung des sich entwickelnden Embryos in Gebiete überwiegend ektodermalen, mesodermalen oder entodermalen Differenzierungstendenzen.

This article firstly criticizes Margaret Archer’s Morphogenetic Approach for being indecisive about the realist notion of emergence it proposes as well as for her inadequate account of structural conditioning. It is argued that critical realists’ conceptualizations of emergence cannot but lead to inconsistencies about the adequate placement of agents as parts of emergent entities. The inconsistencies to which these conceptualizations lead necessitate an anti-realist model of the constitution of societies which takes into account that social structures are existentially dependent (...) upon ideational elaboration. This alternative anti-realist theoretical perspective is provided by Ontogenesis, within the framework of which the realists’ idea of the ‘necessary and internal relations’ give their place to the ontological pervasiveness of the culturally shared imaginary schemata. Archer’s denial of a collective synchronic impact to social forms is implied in her analysis of morphogenetic cycles, according to which, structural elaboration post-dates social interaction; and this denial is also expressed in this very idea of emergent structures. Instead, for Ontogenesis, social forms are synchronically dependent on the collective impact of the differently socially placed agents, who have different interests and material resources, and whose interaction only becomes meaningful when drawing on these culturally shared imaginary schemata.

This article argues against the view put forward by Margaret Archer that there is an irreconcilable divide between realist social theory and structuration theory. Instead, it argues for the systematic articulation of the two theories at both the ontological and the methodological levels. Each has developed a range of insightful and commensurable conceptualizations either missing or underdeveloped in the other. Archer's contention that structuration theory rejects the notion of `analytical dualism' central to the realist approach is shown to be mistaken; (...) Giddens's rejection of `dualism' refers to a different conceptualization of the term. Similarly, Archer's critique of structuration's notion of a `duality' involving structure and agency is rejected by showing that Archer's own morphogenetic approach itself relies upon such a notion. A final section distinguishes between six key problematics of social analysis. It is clear that, for a large number of possible questions within the majority of these problematics, it is a combination of both ontologies that would facilitate the most adequate substantive account.

Critical realism is a philosophy of science, which has made significant contributions to epistemic debates within sociology. And yet, its contributions to ethnographic explanation have yet to be fully elaborated. Drawing on ethnographic data on the health-seeking behavior of HIV-infected South Africans, the paper compares and contrasts critical realism with grounded theory, extended case method and the pragmatist method of abduction. In so doing, it argues that critical realism makes a significant contribution to causal explanation in ethnographic research in three (...) ways: 1) by linking structure to agency; 2) by accounting for the contingent, conjunctural nature of causality; and 3) by using surprising empirical findings to generate new theory. The paper develops the AART research schema and illustrates its strengths by employing a Bourdieusian field analysis as a model for morphogenetic explanation. (shrink)

The change in shape of the C. elegans embryo from an ovoid ball of cells into a worm-shaped larva is driven by three events within the cells of the hypodermis (epidermis): (1) intercalation of two rows of dorsal cells, (2) enclosure of the ventral surface by hypodermis, and (3) elongation of the embryo. While the behavior of the hypodermal cells involved in each of these processes differs dramatically, it is clear that F-actin and microtubules have essential functions in each of (...) these processes, whereas contraction of actomyosin structures appears to be involved specifically in elongation. Molecular analysis of these processes is revealing components specific to C. elegans as well as components found in other systems. Since C. elegans hypodermal cells demonstrate dramatically different behaviors during intercalation, enclosure and elongation, the study of cytoskeletal dynamics in these processes may reveal both unique and conserved activities during distinct epithelial morphogenetic movements.

A theoretical model is presented for pattern formation in an epithelium. The epithelial model consists of a thin, incompressible, viscoelastic membrane on an elastic foundation (substrate), with the component cells assumed to have active contractile properties similar to those of smooth muscle. The analysis includes the effects of large strains and material nonlinearity, and the governing equations were solved using finite differences. Deformation patterns form when the cells activate while lying on the descending limb of their total (active + (...) passive) stress-stretch curve. Various one-dimensional and two-dimensional simulations illustrate the effects of spatial and temporal variations in passive stiffness, as well as the effects of foundation stiffness and stretch activation. The model can be used to examine the mechanical aspects of pattern formation in morphogenetic processes such as angiogenesis and myocardial trabeculation. (shrink)

ABSTRACTFaced with the marketization of Higher Education in England, pedagogy is under pressure in ways that often undermine lecturers’ deeply held values. For instance, this pressure results in the reduction of significant aspects of teaching to narrow metrics and requires universities to operate within intrusive structures that subordinate their pedagogical aims to profit-orientated objectives. In this paper, I analyse the way that people can preserve their agency in this pedagogical context. I guide my analysis with a framework that combines (...) critical realism with Aristotelian virtue ethics and MacIntyre’s ideas of qualities within human practices. I suggest the kinds of qualities that might assist faculty to preserve and advance rich pedagogical projects in the current circumstances. Finally, I use a critical realist morphogenetic approach to argue that people may be able to resist losing their way when faced with ubiquitous performativity regimes. (shrink)

This study was developed around concerns about how indigenous knowledges have been represented and applied in environment and development education. The first phase of the study is a genealogical analysis after Michel Foucault. This probes representations and applications of plant-based indigenous knowledge in selected anthropological, botanical and environmental education texts in southern Africa. The emerging insights were deepened using a Social Realism vantage point after Margaret Archer to shed light on agential issues in environmental education and development contexts. Here (...) her morphogenetic/morphostatic analysis of social transformation or reproduction is used to trace changes in indigenous knowledge representations and applications over time . The second phase uses the same perspectives and tools to extend the analysis of power/knowledge relationships into the interface of indigenous communities and modern institutions in two case study settings in the Eastern Cape of South Africa. This study reveals colonially-derived hegemonic processes of modern/Western scientific institutional representations/interpretations of the knowledges of indigenous communities. It also tracks a continuing trajectory of their dominating and prescriptive mediating control over local knowledges from the pre-colonial context through into the post-colonial period in southern Africa. The analysis reveals how this hegemony is sustained through the deployment of institutional strategies of representation that transform local knowledges into the disciplinary knowledge discourses of modern scientific institutions. These representational strategies therefore generate/reproduce and validate disciplinary discourses about the other, constructing disciplinary 'regimes of truth'. In this way modern institutions appropriate and displace indigenous/local knowledges, silence the voices of local communities and regulate individual and community agency within a continuing subjugation of indigenous knowledges. This study reveals how working within modern institutions and disciplinary knowledges in participative education and development interactions can serve to implicate indigenous researchers in these institutional hegemonic processes. The study also notes evidence of a continued resistance to hegemonic Western knowledge discourses as indigenous communities have sustained many knowledge practices alongside Western knowledge discourses. There is also evidence of a recent emergence of counter-hegemonic indigenous knowledge discourses in environmental education and development practices in southern Africa. It is noted that these have been contingent upon the changing political terrain in southern Africa as this has opened the way for alternative discourses to the dominant conventional Western knowledges in formal education and development contexts. The counterhegemonic discourses invert power/knowledge relations, decentre hegemonic discourses and reposition indigenous knowledges in formal education and development contexts. This study suggests the need to foreground indigenous knowledges as a process of knowledge decolonisation that gives contextual and epistemic relevance to environmental education and development processes. This calls for a need for new strategies to transform existing institutions by creating enabling spaces for the representational inclusion of indigenous knowledges in formal/conventional knowledge discourses and their application in social contexts. This opens up possibilities for plural knowledge representations and for their integrative and reciprocal co-engagement in situated contexts of environmental education and development in southern Africa.

The potential of the vertebrate limb as a model system to study developmental mechanisms is particularly well illustrated by the analysis of the Hox gene network. These genes are probably involved in the establishment of patterns encoding positional information. Their functional organisation during both limb and trunk development are very similar and seem to involve the progressive activation in time, along the chromosome, of a battery of genes whose products could differentially instruct those cells where they are expressed. This (...) process may be common to all organisms that develop according to an anterior‐posterior morphogenetic progression. The possible linkage of this system to a particular mechanism of segmentation as well as its phylogenetic implications are discussed. (shrink)

The inventiveness of life is at the heart of Merleau-Ponty’s ontology because by separating with behaviorism, philosophy could dialogue with the sciences of development to describe several techniques that we successively study as degrees in the normativity of the living : immanent techniques, ecological techniques, bodily intelligence, and, finally, morphogenetic techniques of development. Through this analysis, we demonstrate the thesis of an activation of the living body from its reflex reactivity to its non-intentional projections in its forms.

Introduction and the aim of the study. The paper analyzes the place and role of morphogenetic theory within a framework of contemporary socialtheoretical discourse. M. Archer’s morphogenetic theory and P. Donati’s relational conception are considered as two examples of this discourse. Methods. The authors use analytical methods (analysis, synthesis, etc.), applied in contemporary philosophy of social sciences. Scientific novelty. The key idea of the paper is analyzing morphogenetic social theory in terms of analytical scholasticism as a (...) deviant way of contemporary social theory development. Results. Morphogenetic theory is rather a sociological theory than interdisciplinary social theory; the sophisticated language of “morphogenists” mat seem difficult for other scholars to understand; morphogenetic theory demonstrates indefinite perspectives concerning interdisciplinary or transdisciplinary discourse in the context of contemporary stage of social-humanitarian knowledge development. Conclusions. The status of “morphogenetic theory” among other directions of social theory is by far “peripheral”. (shrink)

Morphogenetische Untersuchungen ermöglichen eine zuverlässige Ermittlung der homologen Elemente in der Lobenlinie der Ammonoidea. Umgekehrt lehrt eine Analyse hypothetischer Vorstellungen, die man sich über die phylogenetischen Zusammenhänge gewisser Ammoneen-Gruppen gebildet hatte, daß sich daraus die Homologie-Beziehungen nicht herleiten lassen. Es besteht keine Konkordanz zwischen den morphologischen Tatbeständen und den stammesgeschichtlichen Konstruktionen, die sich in diesen Fällen als falsch erweisen. Daraus wird der Schluß gezogen, daß der Homologie-Begriff nur unvoreingenommen morphologisch definiert und interpretiert werden kann. Die auf morphologischer Grundlage ermittelten Homologien (...) entscheiden über die Möglichkeit stammesgeschichtlicher Verknüpfungen, nicht aber umgekehrt phylogenetische Deutungen über die Homologie. Ebenso kann die stets unsichere Phylogenie nicht zur Grundlage der Systematik gemacht werden. Auch da liegen die logisch-methodischen Zusammenhänge umgekehrt: Die im System ausgedrückte Formverwandtschaft ist die Basis der Phylogenie und nicht die Phylogenie die der Morphologie. Die Theorie eines Phylogenetischen Systems der Organismen wird abgelehnt.Morphogenetic investigations provide a firm basis for an exact identification of homologous elements in the suture line of ammonoids. On the other hand an analysis of current phylogenetic connections of certain ammonoid groups demonstrates that they give no clue for tracing homologies. There is no agreement between the morphological facts and the phylogenetic fictions, the latter in these cases being definitely wrong. Therefrom it is concluded that the concept of homology can only be defined and interpreted on a morphological basis. The established homologies are decisive for the admissibility of phylogenetic connections and not phylogenetic inferences for the recognition of homologies. In the same manner systematics cannot be based on the always unsafe phylogeny, but only on the actual facts of morphology. The concept of a phylogenetic classification of organisms is rejected.

During the second half of the twentieth century, several philosophers of technology argued that their predecessors had reflected too abstractly and pessimistically on technology. In the view of these critics, one should study technologies empirically in order to fully understand them. They developed several strategies to empirically inform the philosophy of technology and called their new approach the empirical turn. However, they provide insufficient indications of what exactly is meant by empirical study in their work. This leads to the critical (...) question of what counts as an empirically informed philosophy of technology in the empirical turn. In order to answer this question, we first elaborate on the problems that the empirical turn philosophers tried to address; secondly, we sketch their solutions, and, thirdly, we critically discuss their conceptions of empirical study. Our critical analysis of the empirical turn contributes to new efforts to engage in an empirically informed philosophy of technology. (shrink)

Different notions of analysis have been both theorized and put to use in early analytic philosophy. Two of them stand out: connective analysis and analysis as paraphrase. The latter played a central role in the development of analytic philosophy from Frege to Quine and beyond. With the advent of formal semantics of natural language in the 1970s, paraphrase came to be characterizable as translation into a formal “target language”. While I claim that the method cannot achieve its (...) original philosophical aims, I insist that, in spite of them, it is far from being a theoretically empty operation and that it lives on in some contemporary philosophical enterprises.

One of Russell's most important and interesting books which reconciles the materialistic tendency of psychology with the anti-materialistic tendency of physics.

Born in 1838, Mach was a pioneer in the field of physics, having even made an impression on Einstein in his younger life who credited him with being the "Philosophical forerunner of relativity theory." His name is also associated with the speed of sound (as in traveling at Mach "insert-number-here") as well as the Doppler effect. Throughout his career, he was particularly interested in the biological and sensory relationship to physics and science, and naturally, this interest expanded to that of (...) the world of psychological perception and physiological psychology as well as philosophy. The Analysis of Sensations is about just that, the nature of the relationship of physics and the physical sciences to psychological phenomena of sense and perception. It's a fascinating read for anyone looking to expand their knowledge of how the two sides of the same coin meld harmoniously. (shrink)

[Sally Haslanger] In debates over the existence and nature of social kinds such as 'race' and 'gender', philosophers often rely heavily on our intuitions about the nature of the kind. Following this strategy, philosophers often reject social constructionist analyses, suggesting that they change rather than capture the meaning of the kind terms. However, given that social constructionists are often trying to debunk our ordinary (and ideology-ridden?) understandings of social kinds, it is not surprising that their analyses are counterintuitive. This article (...) argues that externalist insights from the critique of the analytic/synthetic distinction can be extended to justify social constructionist analyses. /// [Jennifer Saul] Sally Haslanger's 'What Good Are Our Intuitions? Philosophical Analysis and Social Kinds' is, among other things, a part of the theoretical underpinning for analyses of race and gender concepts that she discusses far more fully elsewhere. My reply focuses on these analyses of race and gender concepts, exploring the ways in which the theoretical work done in this paper and others can or cannot be used to defend these analyses against certain objections. I argue that the problems faced by Haslanger's analyses are in some ways less serious, and in some ways more serious, than they may at first appear. Along the way, I suggest that ordinary speakers may not in fact have race and gender concepts and I explore the ramifications of this claim. (shrink)

This essay examines the quantitative aspects of Greco-Roman science, represented by a group of established disci¬plines, which since the fourth century BC were called mathēmata or mathē¬ma¬tikai epistē¬mai. In the group of mathēmata that in Antiquity normally comprised mathematics, mathematical astronomy, harmonics, mechanics and optics, we have also included geography. Using a dataset based on The Encyclopaedia of Ancient Natural Scientists, our essay considers a community of mathēmatikoi (as they called themselves), or ancient scientists (as they are defined for the (...) purposes of the present paper) from a sociological point of view, focusing on the size of the scientific population known to us and its disciplinary, temporal and geographical distribution. A diachronic comparison of neighboring and partly overlapping communities, ancient scientists and philosophers, allows the pattern of their interrelationship to be traced. An examination of centers of science throughout ancient history reveals that there were five major centers – Athens, Alexandria, Rhodes, Rome and Byzantium/Constantinople – that appear and replace one another in succession as leaders. These conclusions serve to reopen the issue of the place of mathēmata and mathēmatikoi in ancient society. (shrink)

The focus of this article is the analysis of generative mechanisms, a basic concept and phenomenon within the metatheoretical perspective of critical realism. It is emphasized that research questions and methods, as well as the knowledge it is possible to attain, depend on the basic view – ontologically and epistemologically – regarding the phenomenon under scrutiny. A generative mechanism is described as a trans empirical but real existing entity, explaining why observable events occur. Mechanisms are mostly possible to grasp (...) only indirectly by analytical work, based however on empirical observations. In order to achieve such an explanatory analysis, five methodological steps are suggested and discussed, among them abduction and retroduction. These steps are illustrated throughout by examples drawn from empirical research regarding social work practice. The article is concluded with a discussion of the need for knowledge of generative mechanisms. (shrink)

Conceptual analysis of health and disease is portrayed as consisting in the confrontation of a set of criteria—a “definition”—with a set of cases, called instances of either “health” or “ disease.” Apart from logical counter-arguments, there is no other way to refute an opponent’s definition than by providing counter-cases. As resorting to intensional stipulation is not forbidden, several contenders can therefore be deemed to have succeeded. This implies that conceptual analysis alone is not likely to decide between naturalism (...) and normativism. An alternative to this approach would be to examine whether the concept of disease can be naturalized. (shrink)

One of Russell's most important and interesting books which reconciles the materialistic tendency of psychology with the anti-materialistic tendency of physics.

Stakeholder literature tends to presume that effective stakeholder dialogue, occurring directly or indirectly, among a focal firm, local communities, governments, and nongovernmental organizations is desirable for successful firm–stakeholder relationships. Even if theoretically desirable, effective dialogue does not always occur. There are two key theory-informing lessons in Botnia’s Fray Bentos successful green field pulp mill investment and start-up in Western Uruguay. First, critics could not halt the project politically supported by Uruguay in an expanding multi-party international dispute. Second, the Botnia corporate (...) communications process did not succeed in building consensus relationships, and attention was not paid to discourse creating shared meanings among all stakeholders. Participatory relationships were few, and successful dialogue was at best limited to supporters. This article uses discursive analysis to examine how newspaper and press release texts and language used therein both shaped and reflected the dynamically changing nature of firm–stakeholder relations in the Fray Bentos dispute. Despite the focal firm’s professed good intentions to create participatory relationships with its stakeholders during the building project, various stakeholders opposed the project and Botnia was caught in the crossfire of heated debate between Uruguay and Argentina. Three different frames changing over time are identified: the investment frame, the conflict frame, and the political frame. The analysis shows that the relationships between the focal firm and stakeholders involved many meanings only partly shared, due in part to a lack of corporate appreciation for the role of language in managing firm–stakeholder relationships.

Conceptual analysis is undergoing a revival in philosophy, and much of the credit goes to Frank Jackson. Jackson argues that conceptual analysis is needed as an integral component of so-called serious metaphysics and that it also does explanatory work in accounting for such phenomena as categorization, meaning change, communication, and linguistic understanding. He even goes so far as to argue that opponents of conceptual analysis are implicitly committed to it in practice. We show that he is wrong (...) on all of these points and that his case for conceptual analysis doesn't succeed. At the same time, we argue that the sorts of intuitions that figure in conceptual analysis may still have a significant role to play in philosophy. So naturalists needn't disregard intuitions altogether. (shrink)

With the development of teachers’ psychological cognition, the moral education curriculum develops as per the changes in times. Currently, a resurgence of interest on studying teachers’ perceptions of the moral education curriculum has observed. This is because moral education curriculum of each country plays a unique role in the overall design of the country’s education curriculum. However, studies on teachers’ perceptions of the moral education curriculum are scarce, and no framework has been developed to guide the teaching and learning of (...) teachers for the moral education curriculum for schools. The moral education curriculum serves as one of the main vehicles for value education, with teachers as direct executors. It can influence the overall development of the school system and long-term development of a country. Thus, in this paper, we reviewed current literature related to teachers’ perceptions of the moral education curriculum and developed future trends considering teachers’ perceptions of the moral education curriculum in improving existing moral education programs in a country. We identified a list of keywords related to moral education curriculum and teacher perceptions and relevant to the scope of this study. These keywords were used to search the articles from the Scopus and WoS studies. Overall, 32 papers meeting the search criteria were retrieved. Further, we conducted thematic studies, and four themes were successfully identified: the model of teacher perceptions of moral and national education, the dimensions of the teacher ethics model, teaching strategies, and the role of teachers. The results of this study suggested a new framework for research trends in teachers’ perception models, particularly toward the moral education curriculum. This study contributed to the knowledge regarding teaching and learning approaches of moral education considering teachers’ perceptions of the moral education curriculum. The findings of study would benefit future studies and would improve the implementation of a country’s moral education program. (shrink)

From a corporate governance perspective, one of the most important jobs of a firm's top management team is to create and maintain a positive moral environment. Business ethics has long been considered a cornerstone in the field of strategic management and a number of scholars have called for more research in this area over the years. In this paper 658 articles that appeared in "Strategic Management Journal" over the 10-year period between 1996 and 2005 are reviewed for business ethics focus (...) and content. The results reveal that while business ethics research in "Strategic Management Journal" is on the rise, the overall focus on this research stream has been limited. The most prominent ethics theme during the review period was environmentalism, accounting for 30% of all ethics articles. Author affiliations, future research directions, and implications are also discussed. (shrink)
