In France between 1780 and 1815, doctors opened a broad correspondence with medical faculties and public officials about foetal anomalies . Institutional and legal reforms forced doctors to encounter monstrous births with greater frequency, and they responded by developing new ideas about heredity and embryology to explain malformations to public officials. Though doctors achieved consensus on pathogenesis, they struggled to apply these ideas in forensic cases, especially with doubtful sex. Medical networks simultaneously allowed doctors to explore obstetrical techniques, (...) as licensing regulations forced practitioners into emotional encounters with child anomalies. Doctors thus developed a new ethics for treating monstrosities, viewing them as pathological specimens, forensic objects, and obstetrical tragedies. (shrink)

Scientometrics has found many applications in describing, explaining and predicting the scientific status of researchers, educational and research groups, universities, organizations and countries in various national and international arenas. By studying the scientific products of different countries, their status in the production of science can be evaluated. Present study was conducted using a scientometrics approach and using co-word analysis and social network analysis (SNA) to investigate relationships in the field of know­ledge organization. In this regard, research indexed in (...) web of science on the topic of “know­ledge organization” has been analyzed using software including VOSviewer, Gephi, Publish or Perish. The findings of the study show that the most frequently used topics and words are know­ledge organization and classification. Also, the most valuable subject areas were identified based on the maps drawn using the closeness and centrality of indexes, taxonomy, ontology and know­ledge organization systems. Co-authorship analysis revealed that the co-authorship network is discrete and has low-density, with a total of 12,491 citations in all articles. Also, the most prolific author is Hjorland, followed by Smiraglia and Dahlberg. using the co-word map of know­ledge organization, policymakers can plan appropriately through the know­ledge of the research and thematic status of know­ledge organization.

Purpose of the article One of the approaches how to create a concept of a brand is a form of identifying association network in the mind of the consumer and creating semantic maps composed of all associations that are largely shaped by cultural values of consumers. Methodology/methods In the first phase, the author of the study was detecting the associations connected with the Mexican brand alcoholic beer Corona Extra using focus group with a sample of 15 respondents. In the second (...) phase, she analysed the data found in the context of Slovak cultural values and compared them with the results of the secondary research. Scientific objective The article highlights the importance of understanding cultural values of the target market for the management and brand communication across cultures. The main objective of the survey was to determine how the Slovak respondents perceive selected sample of global brand, to compare the findings of a secondary survey conducted at German and Spanish students, and in the final phase of the research to analyse the data found in the context of the cultural dimensions of respondents. Findings On one hand, the associations formed by consumers about Corona Extra mutually differ depending on the countries surveyed. On the other hand, they correspond to the cultural values of the nation, and thus confirm the strong influence of the cultural aspects of the brand perception. Conclusions The presented article confirms, that there will always be an open space for the extensive research in global marketing and cross-cultural differences in consumer behaviour. Exploring cultural aspects of communication of global brands will benefit not only in terms of increasing the efficiency of advertising campaigns, but also for the mutual knowledge and understanding between cultures.

We introduce the notion of complexity, first at an intuitive level and then in relatively more concrete terms, explaining the various characteristic features of complex systems with examples. There exists a vast literature on complexity, and our exposition is intended to be an elementary introduction, meant for a broad audience. -/- Briefly, a complex system is one whose description involves a hierarchy of levels, where each level is made of a large number of components interacting among themselves. The time evolution (...) of such a system is of a complex nature, depending on the interactions among subsystems in the next level below the one under consideration and, at the same time, conditioned by the level above, where the latter sets the context for the evolution. Generally speaking, the interactions among the constituents of the various levels lead to a dynamics characterized by numerous characteristic scales, each level having its own set of scales. What is more, a level commonly exhibits ‘emergent properties’ that cannot be derived from considerations relating to its component systems taken in isolation or to those in a different contextual setting. In the dynamic evolution of some particular level, there occurs a self-organized emergence of a higher level and the process is repeated at still higher levels. -/- The interaction and self-organization of the components of a complex system follow the principle commonly expressed by saying that the ‘whole is different from the sum of the parts’. In the case of systems whose behavior can be expressed mathematically in terms of differential equations this means that the interactions are nonlinear in nature. -/- While all of the above features are not universally exhibited by complex systems, these are nevertheless indicative of a broad commonness relative to which individual systems can be described and analyzed. There exist measures of complexity which, once again, are not of universal applicability, being more heuristic than exact. The present state of knowledge and understanding of complex systems is itself an emerging one. Still, a large number of results on various systems can be related to their complex character, making complexity an immensely fertile concept in the study of natural, biological, and social phenomena. -/- All this puts a very definite limitation on the complete description of a complex system as a whole since such a system can be precisely described only contextually, relative to some particular level, where emergent properties rule out an exact description of more than one levels within a common framework. -/- We discuss the implications of these observations in the context of our conception of the so-called noumenal reality that has a mind-independent existence and is perceived by us in the form of the phenomenal reality. The latter is derived from the former by means of our perceptions and interpretations, and our efforts at sorting out and making sense of the bewildering complexity of reality takes the form of incessant processes of inference that lead to theories. Strictly speaking, theories apply to models that are constructed as idealized versions of parts of reality, within which inferences and abstractions can be carried out meaningfully, enabling us to construct the theories. -/- There exists a correspondence between the phenomenal and the noumenal realities in terms of events and their correlations, where these are experienced as the complex behavior of systems or entities of various descriptions. The infinite diversity of behavior of systems in the phenomenal world are explained within specified contexts by theories. The latter are constructs generated in our ceaseless attempts at interpreting the world, and the question arises as to whether these are reflections of `laws of nature' residing in the noumenal world. This is a fundamental concern of scientific realism, within the fold of which there exists a trend towards the assumption that theories express truths about the noumenal reality. We examine this assumption (referred to as a ‘point of view’ in the present essay) closely and indicate that an alternative point of view is also consistent within the broad framework of scientific realism. This is the view that theories are domain-specific and contextual, and that these are arrived at by independent processes of inference and abstractions in the various domains of experience. Theories in contiguous domains of experience dovetail and interpenetrate with one another, and bear the responsibility of correctly explaining our observations within these domains. -/- With accumulating experience, theories get revised and the network of our theories of the world acquires a complex structure, exhibiting a complex evolution. There exists a tendency within the fold of scientific realism of interpreting this complex evolution in rather simple terms, where one assumes (this, again, is a point of view) that theories tend more and more closely to truths about Nature and, what is more, progress towards an all-embracing ‘ultimate theory’ -- a foundational one in respect of all our inquiries into nature. We examine this point of view closely and outline the alternative view -- one broadly consistent with scientific realism -- that there is no ‘ultimate’ law of nature, that theories do not correspond to truths inherent in reality, and that successive revisions in theory do not lead monotonically to some ultimate truth. Instead, the theories generated in succession are incommensurate with each other, testifying to the fact that a theory gives us a perspective view of some part of reality, arrived at contextually. Instead of resembling a monotonically converging series successive theories are analogous to asymptotic series. -/- Before we summarize all the above considerations, we briefly address the issue of the complexity of the {\it human mind} -- one as pervasive as the complexity of Nature at large. The complexity of the mind is related to the complexity of the underlying neuronal organization in the brain, which operates within a larger biological context, its activities being modulated by other physiological systems, notably the one involving a host of chemical messengers. The mind, with no materiality of its own, is nevertheless emergent from the activity of interacting neuronal assemblies in the brain. As in the case of reality at large, there can be no ultimate theory of the mind, from which one can explain and predict the entire spectrum of human behavior, which is an infinitely rich and diverse one.

Coherence and correspondence are classical contenders as theories of truth. In this paper we examine them instead as interacting factors in the dynamics of belief across epistemic networks. We construct an agent-based model of network contact in which agents are characterized not in terms of single beliefs but in terms of internal belief suites. Individuals update elements of their belief suites on input from other agents in order both to maximize internal belief coherence and to incorporate ‘trickled in’ (...) elements of truth as correspondence. Results, though often intuitive, prove more complex than in simpler models (Hegselmann & Krause 2002, 2006; Grim, Singer, Reade & Fisher 2015). The optimistic finding is that pressures toward internal coherence can exploit and expand on small elements of truth as correspondence is introduced into epistemic networks. Less optimistic results show that pressures for coherence can also work directly against the incorporation of truth, particularly when coherence is established first and new data is introduced later.

Deep Neural Networks (DNNs) are becoming increasingly important as scientific tools, as they excel in various scientific applications beyond what was considered possible. Yet from a certain vantage point, they are nothing but parametrized functions fθ(x)\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\varvec{f}_{\varvec{\theta }}(\varvec{x})$$\end{document} of some data vector x\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\varvec{x}$$\end{document}, and their ‘learning’ is nothing but an iterative, algorithmic fitting of the parameters to data. Hence, what could (...) be special about them as a scientific tool or model? I will here suggest an integrated perspective that mediates between extremes, by arguing that what makes DNNs in science special is their ability to develop functional concept proxies (FCPs): Substructures that occasionally provide them with abilities that correspond to those facilitated by concepts in human reasoning. Furthermore, I will argue that this introduces a problem that has so far barely been recognized by practitioners and philosophers alike: That DNNs may succeed on some vast and unwieldy data sets because they develop FCPs for features that are not transparent to human researchers. The resulting breach between scientific success and human understanding I call the ‘Actually Smart Hans Problem’. (shrink)

ArgumentUp until the French Revolution, European mathematics was an “aristocratic” activity, the intellectual pastime of a small circle of men who were convinced they were collaborating on a universal undertaking free of all space-time constraints, as they believed they were ideally in dialogue with the Greek founders and with mathematicians of all languages and eras. The nineteenth century saw its transformation into a “democratic” but also “patriotic” activity: the dominant tendency, as shown by recent research to analyze this transformation, seems (...) to be the national one, albeit accompanied by numerous analogies from the point of view of the processes of national evolution, possibly staggered in time. Nevertheless, the very homogeneity of the individual national processes leads us to view mathematics in the context of the national-universal tension that the spread of liberal democracy was subjected to over the past two centuries. In order to analyze national-universal tension in mathematics, viewed as an intellectual undertaking and a profession of the new bourgeois society, it is necessary to investigate whether the network of international communication survived the political, social, and cultural upheavals of the French Revolution and the European wars waged in the early nineteenth century, whether national passions have transformed this network, and if so, in what way. Luigi Cremona's international correspondence indicates that relationships among individuals have been restructured by the force of national membership, but that the universal nature of mathematics has actually been boosted by a vision shared by mathematicians from all countries concerning the role of their discipline in democratic and liberal society as the basis of scientific culture and technological innovation, as well as a basic component of public education.

Summary This article focuses on the relevance of Alexander von Humboldt's correspondence in the formation of transatlantic scientific networks at the beginning of the nineteenth century. Apart from connecting Humboldt with scientists and scholars worldwide, his correspondence turned out to be a fundamental tool for assuring the material conditions and the social and scientific connections he needed to carry out his research on the Spanish colonies and to simultaneously diffuse his achievements on the European side (...) of the Atlantic. His contact with Hispanic American scientists and with the local elites enabled him to build a broad social network, gaining access to key material, human and intellectual resources. The letters sent to scientists, scientific institutions and noblemen in Europe, for their part, kept Humboldt's European correspondents informed about his activities in Hispanic America, contributing to the validation of his work before the scientific community and the fulfilment of the duties resulting from the political and institutional support he received both before and during his travels. This stresses the importance of strategic social groups and their cooperation in the framework of exploratory travels as a means to gaining access to resources in the peripheries. It also reveals the scientist's dependence on all those who supported his research: kings, barons, botanical gardens, universities, and academies. (shrink)

In biological terms, human consciousness appears as a feature associated with the func- tioning of the human brain. The corresponding activities of the neural network occur strictly in accord with physical laws; however, this fact does not necessarily imply that there can be a comprehensive scientific theory of conscious- ness, despite all the progress in neurobiology, neuropsychology and neurocomputation. Pre- dictions of the extent to which such a theory may become possible vary widely in the scien- tific community. There (...) are basic reasons - not only practical but also epistemological - why the brain-mind relation may never be fully “decod- able” by general finite procedures. In partic- ular self-referential features of consciousness, such as self-representations involved in strate- gic thought and dispositions, may not be resolv- able in all their essential aspects by brain analy- sis. Assuming that such limitations exist, objec- tive analysis by the methods of natural science cannot, in principle, fully encompass subjective, mental experience. (shrink)

This article uses the methods of citation and network analysis to map the global structure of the intellectual field and its development over time. Through the case study of Mersenne's, Oldenburg's and Darwin's correspondences, we show how looking at letters as a corpus of data can provide a global representation of the evolving conversation going on in the Republic of Letters and in intellectual and scientific fields. Aggregating general correspondences in electronic format offers a global portrait of the evolving (...) composition of the intellectual and scientific scene, its changing foci of interests and the fortune of the intellectual discussions as expressed in cited persons in the letters. Such tools help replace a purely metaphoric use of the term “network” by a visible map of the intellectual relations between people on which well defined calculations of the centrality of the positions of different actors can be made as well as their evolution over time. These techniques provide welcome additions to the tool kit of scholars in an age where the computer and the web offer new ways of mapping and mining the rich store of information contained in intellectual correspondences. ☆ I would like to thank Alain Couillard for the production of the figures and Vincent Larivière and the anonymous referees of the journal for useful comments and suggestions on an earlier version of this paper. Thanks also to the many comments received over the last 10 years as I presented preliminary results of this research at the REHSEIS research center of Université of Paris VII in 1999, the Dibner Institute for the History of Science and Technology at MIT in 2000, at Pietro Corsi's seminar at Oxford University in 2007 and at the History Department of Ottawa University in 2010.

Network analysis views complex systems as networks with well-defined structural properties that account for their complexity. These characteristics, which include scale-free behavior, small worlds and communities, are not to be found in networks such as random graphs and lattices that do not correspond to complex systems. They provide therefore a robust ground for claiming the existence of “complex networks” as a non-trivial subset of networks. The theory of complex networks has thus been successful in making (...) systematically explicit relevant marks of complexity in the form of structural properties, and this success is at the root of its current popularity. Much less systematic has been, on the other hand, the definition of the properties of the building components of complex networks. The obvious assumption is that these components must be nodes and links. Generally, however, the internal structure of nodes is not taken into account, and links are serendipitously identified by the perspective with which one looks at the network to be analyzed. For instance, if the nodes are Web pages that contain information about scientific papers, one point of view will match the relevant links with hyperlinks to similar Web pages, and another with citations of other articles. We intend to contribute here a systematic approach to the identification of the components of a complex network that is based on information theory. The approach hinges on some recent results arising from the convergence between the theory of complex networks and probabilistic techniques for content mining. At its core there is the idea that nodes in a complex network correspond to basic information units from which links are extracted via methods of machine learning. Hence the links themselves are viewed as emergent properties, similarly to the broader structural properties mentioned above. Indeed, beside rounding up the theory, this approach based on learning has clear practical benefits, in that it makes networks emerge from arbitrary information domains. We provide examples and applications in a variety of contexts, starting from an information-theoretic reconstruction of the well-known distinction between “strong links” and “weak links” and then delving into specific applications such as business process management and analysis of policy making.

This paper examines the correspondence and contacts between Galileo and a number of French intellectuals. It demonstrates that exchanges between Galileo and those Frenchmen did much to stimulate an interest in new scientific ideas in France, especially in astronomy; for example, Galileo provided a number of good telescopic lenses that did much to establish observational astronomy in France. The Frenchmen for their part provided Galileo with considerable useful information. Several were very active in his support after the condemnation (...) of 1633 and in publishing his later works. The paper further demonstrates the extent of the network of intellectuals who corresponded with Galileo and each other across Europe in the early seventeenth century. (shrink)

Pierre des Noyers, secretary of Queen of Poland Louise-Marie Gonzaga, is known for his role as a messenger, envoy, court journalist and sometimes propagandist. His work as an unofficial diplomat for the Queen and ambassador for France is less famous though no less interesting. Even though he was already quite involved in these time-consuming tasks, Pierre des Noyers also acted as a scientific intermediary for the quite curious Queen Louise-Marie of Poland. He maintained contacts with many scholars from France (...) and Italy. He could nurture this network thanks to his position as an informal diplomat at the court of the Queen and his dedication to science in general. Even by discarding his most official and political letters, his known correspondence amounts to several hundred letters written in a period of around 50 years to various friends and scholars. Roberval, Gassendi, Boulliau, Hevelius or Pascal are among these contacts and he plays for most of them the role of a scientific intermediary sharing with them observations, books and anecdotes. His letters are filled with astronomical observations, prodigies and prophecies. Des Noyers was also a practitioner of science. Having possessed a rather large collection of scientific instruments he always sought the improved ones and his daily life was marked by scientific studies. He wrote meteorological bulletins for Academia del Cimento in Florence, studied the measurement of time, observed the sun and showed interest in the inner workings of the human body. This article will delve further into more scientific aspects of Pierre des Noyers’s life, both at the court of Louise-Marie and outside. The first part presents a rough overview of the secretary’s contacts in the scientific environment of 17th Century France and how they were used to connect scholars from Poland with this environment. The second part of this work presents Pierre des Noyers’s practice of science as a tool to understand the world and for which utmost diligence in measurement and practice is required. The last part focuses on des Noyers’s application of this scientific method in two, now pseudo-scientific fields: astrology and divination. (shrink)

In this study, we sorted out the research hotspots in sports science by bibliometric method and also used social network analysis to explore the relationship between knowledge networks and their scientific performance. We found 38 high-frequency keywords with obvious curricular nature or classical direction of sports science research and 4 high-frequency research groups. The topics of hotspots covered the secondary disciplines of sports science: physical education and training, national traditional sports, sports human science, and sports humanities and sociology. (...) However, sports human science research is less; therefore, accelerating the research of sports human science is the focus of future research. Meanwhile, we use social network structure analysis to study the relationship between knowledge elements in knowledge networks and their scientific performance. In addition to betweenness centrality, the closeness centrality, clustering coefficient, and structural holes of knowledge elements are significantly and positively related to their influence. In the relationship between knowledge elements and productivity, betweenness centrality and closeness centrality show significant positive correlations, and clustering coefficient and structural hole show significant negative correlations. Therefore, knowledge networks can be used to predict the scientific performance of knowledge elements. (shrink)

Traditional eliminativism is the view that a term should be eliminated from everyday speech due to failures of reference. Following Edouard Machery, we may distinguish this traditional eliminativism about a kind and its term from a scientific eliminativism according to which a term should be eliminated from scientific discourse due to a lack of referential utility. The distinction matters if any terms are rightly retained for daily life despite being rightly eliminated from scientific inquiry. In this article, (...) I argue that while scientific eliminativism for pain may be plausible, traditional eliminativism for pain is not. I discuss the pain eliminativisms offered by Daniel Dennett and Valerie Hardcastle and argue that both theorists, at best, provide support for scientific eliminativism for pain, but leave the folk-psychological notion of pain unscathed. One might, however, think that scientific eliminativism itself entails traditional eliminativism—for pain and any other kind and corresponding term. I argue that this is not the case. Scientific eliminativism for pain does not entail traditional eliminativism about anything. (shrink)

The Cybersyn project has lately received increased attention. In this article, we study the local technical antecedents of Stafford Beer's Cybersyn project in Chile, particularly regarding Cybernetics and Systems ideas and local computing and networking developments. We show that the Cybersyn project in Chile was hosted by a rich intellectual environment that understood Cybernetics and Systems ideas; that it found a mature computer community and infrastructure whose high point was the State Computing Enterprise EMCO/ECOM, and an advanced networking experience whose (...) flagship was the automation of the State Bank that involved a pioneering network of teleprocess. In summary, this paper attempts to unveil the deep historical background over which the globally unique cybernetic experiment called Cybersyn flourished. (shrink)

Pushing through a logical continuum of closed-to open-system views of organizations necessarily changes the conceptualization of a firm from a strongly bounded entity to a configuration of networks and sub-networks, which exists and operates in a larger systemic network configuration. We unfold a classification of management processes corresponding to views of the firm along the closed/open-systems continuum. We examine ethical issues that are likely to devolve from these classes of management processes, and we suggest typical means by which (...) managers will attempt to control their firms' exposure to such issues. The final class of management processes examined focuses on the achievement of out-comes that are mutually satisfactory in the set of networks and sub-networks that constitute the focal firm, and that support the sustainability of the whole system. The article contributes to organizational theory, business ethics, and computer and information ethics by providing a comprehensive analysis of the impact of managerial views of the firm and of networks - virtual, social, informational - on managerial processes and on our understanding of how business ethics issues are linked to perceptions of what a firm is, does, and can do.

Neural substrates of fatigue in traumatic brain injury are not well understood despite the considerable burden of fatigue on return to productivity. Fatigue is associated with diminishing performance under conditions of high cognitive demand, sense of effort, or need for motivation, all of which are associated with cognitive control brain network integrity. We hypothesize that the pathophysiology of TBI results in damage to diffuse cognitive control networks, disrupting coordination of moment-to-moment monitoring, prediction, and regulation of behavior. We investigate the (...) cingulo-opercular and frontoparietal networks, which are engaged to sustain attention for task and maintain performance. A total of 61 individuals with mild TBI and 42 orthopedic control subjects participated in functional MRI during performance of a constant effort task requiring altering the amount of effort utilized to manually squeeze a pneumostatic bulb across six 30-s trials. Network-based statistics assessed within-network organization and fluctuation with task manipulations by group. Results demonstrate small group differences in network organization, but considerable group differences in the evolution of task-related modulation of connectivity. The mild TBI group demonstrated elevated CO connectivity throughout the task with little variation in effort level or time on task, while CO connectivity diminished over time in controls. Several interregional CO connections were predictive of fatigue in the TBI group. In contrast, FP connectivity fluctuated with task manipulations and predicted fatigue in the controls, but connectivity fluctuations were delayed in the mild traumatic brain injury group and did not relate to fatigue. Thus, the mTBI group’s hyper-connectivity of the CO irrespective of task demands, along with hypo-connectivity and delayed peak connectivity of the FP, may allow for attainment of task goals, but also contributes to fatigue. Findings are discussed in relation to performance monitoring of prediction error that relies on internal cues from sensorimotor feedback during task performance. Delay or inability to detect and respond to prediction errors in TBI, particularly evident in bilateral insula-temporal CO connectivity, corresponds to day-to-day fatigue and fatigue during task performance.

A scientific community can be modeled as a collection of epistemic agents attempting to answer questions, in part by communicating about their hypotheses and results. We can treat the pathways of scientific communication as a network. When we do, it becomes clear that the interaction between the structure of the network and the nature of the question under investigation affects epistemic desiderata, including accuracy and speed to community consensus. Here we build on previous work, both our own and (...) others’, in order to get a firmer grasp on precisely which features of scientific communities interact with which features of scientific questions in order to influence epistemic outcomes.

SUMMARYEighteenth-century scientific translation was not just a linguistic or intellectual affair. It included numerous material aspects requiring a social organization to marshal the indispensable human and non-human actors. Paratexts and actors' correspondences provide a good observatory to get information about aspects such as shipments and routes, processes of translation and language acquisition, texts acquisition and dissemination.The nature of scientific translation changed in France during the second half of the eighteenth century. Beside solitary translators, it also happened to become (...) a collective enterprise, dedicated to providing abridgements or enriching the learned journals with full translations of the most recent foreign texts. That new trend clearly had a decisive influence on the nature of the scientific press itself. A way to set up science as a social activity in the provincial capital of Dijon, translation required a local and international network for acquiring the linguistic and scientific expertise, along with the original texts, as quickly as possible. Laboratory results and mineralogical observations were used to compare material facts with those described in the original text. By providing a double kind of validation – with both the experiments and the translations – the laboratory thus happened to play a major role in translation. (shrink)

There is a gap between two different modes of computation: the symbolic mode and the subsymbolic (neuron-like) mode. The aim of this paper is to overcome this gap by viewing symbolism as a high-level description of the properties of (a class of) neural networks. Combining methods of algebraic semantics and non-monotonic logic, the possibility of integrating both modes of viewing cognition is demonstrated. The main results are (a) that certain activities of connectionist networks can be interpreted as non-monotonic (...) inferences, and (b) that there is a strict correspondence between the coding of knowledge in Hopfield networks and the knowledge representation in weight-annotated Poole systems. These results show the usefulness of non-monotonic logic as a descriptive and analytic tool for analyzing emerging properties of connectionist networks. Assuming an exponential development of the weight function, the present account relates to optimality theory – a general framework that aims to integrate insights from symbolism and connectionism. The paper concludes with some speculations about extending the present ideas. (shrink)

The pandemic seems to have reversed the relationship between Knowledge and Communication: communication prevails and determines the significance and meaning of events, just as it happened in premodern times. Public knowledge is being eroded. Post-modern scientific knowledge, already unfathomably complex and technical, is both evolving and becoming obsolete at such great speed that it unveils, paradoxically, the vulnerability and relativity of the truth it claims to grasp. Alongside truth-correspondence and truth-coherence, the older truth-significance also makes itself known. Amplified (...) by the resonance chamber of new media and social networks, the latter can emerge as the “post-truth” and “fake-news” that transform Public Communication into Public Relations.

In recent years, historians of science have increasingly turned their attention to the “print culture” of early modern science. These studies have revealed that printing, as both a technology and a social and economic system, structured the forms and meanings of natural knowledge. Yet in early modern Europe, naturalists, including John Aubrey, John Evelyn, and John Ray, whose work is discussed in this paper, often shared and read scientific texts in manuscript either before or in lieu of printing. Scribal (...) exchange, exemplified in the circulation of writings like commonplace books, marginalia, manuscript treatises, and correspondence, was the primary means by which communities of naturalists constructed scientific knowledge. Print and manuscript were necessary partners. Manuscript fostered close collaboration, and could be circulated relatively cheaply; but, unlike print, it could not reliably secure priority or survival for posterity. Naturalists approached scribal and print communication strategically, choosing the medium that best suited their goals at any given moment. As a result, print and scribal modes of disseminating information, constructing natural knowledge, and organizing communities developed in tandem. Practices typically associated with print culture manifested themselves in scribal texts and exchanges, and vice versa. “Print culture” cannot be hived off from “scribal culture.” Rather, in their daily jottings and exchanges, naturalists inhabited, and produced, one common culture of communication.

In lieu of an abstract, here is a brief excerpt of the content: Classics and Complexity in Walden’s “Spring” M. D. USHER In 1843, two years before Henry Thoreau built his cabin at Walden Pond, the Fitchburg Railroad laid down tracks through the woods near the Pond for its line connecting Boston to Fitchburg. The original Fitchburg Line, at 54 miles long, was, until 2010, the longest run in the present -day MBTA Commuter Rail system. And it is one of (...) the oldest railways in New England. By 1900, fortunes swelled and the Fitchburg’s Hoosac Tunnel Line took passengers and goods westward toward Chicago. The Lake Champlain Route connected Boston to points north like Burlington, Vermont. (See Figure 1.) arion 27.1 spring/summer 2019 Figure 1 (left): Advertisement for the Hoosac Tunnel Route in The New England Magazine (Vol. 21, Issue 6, February, 1900). Figure 2 (right): Herbert Wendell Gleason. The Fitchburg Railroad and Walden Pond in winter, Concord, Mass., March 24, 1920. Courtesy Concord Free Public Library. The Railroad was literally a fixture in Thoreau’s landscape. Its tracks pass remarkably close to Walden Pond (Figure 2), and the Fitchburg Line—both its reality and the specter of it—is practically a character in his writing: “I usually go to the village along its causeway, and am, as it were, related to society by this link,” Thoreau writes in “Sounds,” a chapter of Walden that contains what must be one of the most picturesque odes (or laments) to rail travel and commerce in all of American literature: The engine’s whistle, Thoreau complains, pierces the still silence of his idyllic retreat like a screaming hawk circling a farmer’s field, its billows of steam an ominous harbinger of “this travelling demi-god, this cloud-compeller.”1 Thoreau’s frequent, customary walks into Concord along the railroad tracks took him through a heavily excavated stretch of the line known as the Deep Cut, to which he returned again and again each year in early spring, even after leaving the cabin, to observe and to record his observations. The leaf-shaped sand flows and trickling surface erosion caused by melting frost in the banks of the Deep Cut are elaborately described in Thoreau’s chapter in Walden entitled “Spring,” what Laurence Buell calls the “high point of Thoreau’s epic.”2 And yet, in spite of the universal acclaim of this passage as a literary tour de force, it has not received the full attention it deserves. What warrants fresh consideration first and foremost is “Spring”’s deep-rootedness in classical sources. Many classical influences, allusions, and a good deal of etymological word play have gone so far unnoticed. The chapter is also important because it describes, by intimation, what contemporary scientists now call emergence. Emergent phenomena are properties or behaviors that arise in systems as a result of complex, dynamic interactions amongst constituent parts, including changes to a system brought about by human interventions3—not only, e.g., climate change and wildfires, but also traffic patterns and terrorist networks; kidney function in the body; the rings of Saturn. As he tries to capture the essence of the 114 classics and complexity in WALDEN’s “spring” Deep Cut and interpret its significance, Thoreau adumbrates this concept, but also grapples ingeniously with broader issues of perennial concern—the relationship of Nature to Culture, for example, of Wilderness to Civilization, of Science to the Humanities—making “Spring” not only a probing work of eco-criticism and environmental philosophy, but of scientific reflection and poetic experiment as well. In short, Thoreau’s “Spring” is that rare work of classical reception that transmits both literary and scientific insight. Perhaps at this point, in lieu of accolades, it is best to let Thoreau start speaking for himself. What I offer in the following pages is a commentary on the Deep Cut passage from “Spring.” Classical references and aspects of systems theory will be explained and contextualized as they emerge, as it were, from Thoreau’s text. The whole chapter corresponds to pages 289–308 in Cramer’s edition of Walden—26 paragraphs all told, of which only the relevant ones are printed and annotated here.

Decades of psychological research have been aimed at modeling how people learn features and categories. The empirical validation of these theories is often based on artificial stimuli with simple representations. Recently, deep neural networks have reached or surpassed human accuracy on tasks such as identifying objects in natural images. These networks learn representations of real‐world stimuli that can potentially be leveraged to capture psychological representations. We find that state‐of‐the‐art object classification networks provide surprisingly accurate predictions of human (...) similarity judgments for natural images, but they fail to capture some of the structure represented by people. We show that a simple transformation that corrects these discrepancies can be obtained through convex optimization. We use the resulting representations to predict the difficulty of learning novel categories of natural images. Our results extend the scope of psychological experiments and computational modeling by enabling tractable use of large natural stimulus sets. (shrink)

Prediction is one of the major challenges in complex systems. The prediction methods have shown to be effective predictors of the evolution of networks. These methods can help policy makers to solve practical problems successfully and make better strategy for the future. In this work, we focus on exporting countries’ data of the International Trade Network. A recommendation system is then used to identify the products that correspond to the production capacity of each individual country but are somehow overlooked (...) by the country. Then, we simulate the evolution of the country’s fitness if it would have followed the recommendations. The result of this work is the combination of these two methods to provide insights to countries on how to enhance the diversification of their exported products in a scientific way and improve national competitiveness significantly, especially for developing countries.

In spite of these efforts in the 1920s and 1930s to initiate ongoing research on contraception, the subject of birth control remained a problem of concern primarily to the social activist rather than to the research scientist or practicing physician.80 In the 1930s, as has been shown, American scientists turned to the study of other aspects of reproductive physiology, while American physicians, anxious to eliminate the moral and medical dangers of contraception, only reluctantly accepted birth control as falling within their (...) professional domain.As a result, the problem of cheap, effective, and safe contraception was not solved by these earliest attempts. Consideration of the subject was initiated afresh by private philanthropy after World War II, sparked by a new wave of interest in population studies.81 Summarizing such efforts to support research in the reproductive sciences, a recent Ford Foundation study has noted: “To initiate and sustain serious research in the reproductive sciences has required for more than half a century concerted effort by interested individuals and private organizations, mainly from outside the mainstreams of the biomedical research community.”82The early laboratory research on chemical contraception described in this paper was but one important outcome of the concerted effort made by reformers in the 1920s to eliminate a variety of social problems thought to derive from excessive fertility. Scientific arguments and expertise were employed to advocate reform as well as to define the appropriate solution to such social problems. Scientists were recruited as advocates for the movement, but they were also employed as researchers in laboratory investigations sponsored by these same reformers.Sponsors of these early laboratory studies noted the difficulty of obtaining first-class investigators.83 The routine analyses necessary for such research, as well as the traditional scientific aversion to applied problems, provide only a partial explanation for this response. The real difficulty lay in recruiting investigators to a field that had previously been taboo. Once opened up — first as socially relevant, and finally as scientifically sound — there was much interest in this area, and the appeal to researchers of the scientific issues surrounding fertility and reproduction soon surpassed that of the reforming value of birth control.A survey of the kinds of experimental investigations sponsored by birth control advocates indicates the range of physiological problems explored by contraceptive research. The most definitive work was done on the efficacy and safety of spermicides, but the potential of other contraceptive methods was also examined. Investigators attempted to develop spermatoxins that would effectively immunize women against sperm, and they also tried to elucidate the mechanism of hormonal control of reproduction. In fact, speculations about the possible hormonal manipulation of fertility were expressed at the Seventh International Birth Control Conference held in Zurich in 1930.84In the 1920s, clinical studies were undertaken to assess the effectiveness of the various birth control methods. Laboratory investigators complemented this work by screening spermicides for safety and testing for their ability to kill sperm. There were a variety of birth control preparations on the market, but no one really knew whether these were effective or even safe.85 Although the physiology of other major organ systems was well advanced, the scientific study of reproductive physiology and contraceptive technology was clearly in its infancy in this period. Routine analyses simply could not be conducted, because the fundamental research establishing baselines had not yet been done. Scientists used this fact to redirect attention to basic research on reproduction.Laboratory research on contraception indicated important unexplored areas for physiological investigation. Social activists, who had encouraged prominent scientists to become interested in both the social value and the genetic implications of birth control, found these investigators revising the goals of their research. The biologists had formed their own network and had begun to seek out funding, reformulating the justification for sponsorship of further investigations. The eugenic motivations underlying these studies, which had initially made them theoretically attractive to biologists, were gradually eroded. Concern with “human evolution” ceded its place to interest in physiological mechanisms. Crew and others began to note that the use of biological theory to justify essentially political decisions had serious limitations. Biologists had become uncomfortable with those very arguments which had originally captured their interest. Recognition of the potential political abuse wrought by applying scientific principles to society was expressed by Crew just one year after the Zurich meeting. Referring to previous assessments of the role of sex in reproduction, he generalized: “In the past the biologist has justified feudalism, Manchester Liberalism, socialism and every other type of social organization and political programme by reference to selected biological phenomena.”86 By 1932 Crew had also begun to question the biological logic of regulated breeding, and had made it clear to his American sponsor that there was no simple correspondence between the practice of birth control and the genetic improvement of the human race.87Biologists further began to recognize, however, that although the hopeful genetic solution to human problems was probably an illusion, contraception still remained one tangible means to alleviate, human misery. Some laboratory scientists, like Crew, acknowledged the applicability of their own particular skills to this problem. For a few brief years, social needs and scientific goals were mutually supportive and closely intertwined. But as laboratory researchers gained interest in the study of reproduction and established their own priorities in this field, they temporarily withdrew from the arena of debate over birth control as an important mechanism for social reform.With the rise of Hitler, the genetic arguments for birth control rapidly lost their appeal. But by that time the scientific problem of how to achieve effective contraception had entered the professional consciousness. Both physicians and scientists began to be aware of birth control as a subject within their domain of expertise, although outside the principal focus of their research. Scientific discussion of birth control permanently altered from a question of justification to a problem of method: How could one achieve reliable and safe contraception? This had been Sanger's and Dickinson's goal from the beginning. Laboratory scientists had indeed been persuaded to undertake this work; this research had in turn affected biologists' perceptions of the whole field of reproductive physiology, encouraging further study of reproductive mechanisms. The promise of new knowledge provided for continued funding of this research, despite the caution by scientists that the social benefits would not be as immediate or as far-reaching as advocates and they themselves had first argued.The activities of birth control activists and their supporting agencies, and the financial backing of private contributors and foundations, notably the Rockefeller philanthropies, provided an important new stimulus to the development of research on the biology of reproduction in the late 1920s and early 1930s. Biologists were able to claim an enlarged realm of issues for scientific study through their activities as advocates and as investigators for the birth control movement. At the same time, they promised as-yet-undiscovered possibilities for regulating human reproduction once its physiology was understood. The knowledge and control that they promised lay in understanding the whole reproductive cycle — not merely in evaluating the toxic effects of presumptive spermicides.Chemical spermicides never summoned the interest of scientists as the contraceptive pill was to do, yet that research did reinforce the widespread perceptions of scientific research as essential to social reform. Spermicide investigations focused research efforts in reproductive biology by challenging traditional taboos, defining problems for further study, and providing laboratory investigators the opportunity to assert the social and scientific value of their own skills. Crew echoed this attitude as he observed in 1934:Man has turned from the adventurous conquest of his environment to the conquest of himself. To-day is the day of biological invention, eagerly used for the control of the undesirable and the unwanted. Sex and reproduction are no longer hedged around by myth and taboo; they are no longer accepted as mysteries that defy understanding. They are matters inviting examination and explanation; they are regarded as expressions of physico-chemical forces, the nature of which is to be displayed. It is accepted that when knowledge is sufficient, control will be absolute, and, though knowledge is not yet sufficient, readers... must be persuaded to the view that this will not always be so.88The synergism between reproductive biology and social needs has been temporary and sporadic, but recurring, since the 1920s. Scientific research programs have clearly been influenced by issues raised by public debate. Nevertheless, reproductive biologists have continued to assert their own professional goals. For the most part, they have rejected problems without inherent scientific interest and have spurned applied research except as it has had a direct bearing on current research themes. This attitude, apparent among American and British investigators in the 1930s, created the intellectual context for the invention and acceptance of the technically sophisticated oral contraceptive pill. It did not foster the production and improvement of the simple, safe, effective, and cheap vaginal contraceptive desired by early birth control advocates. (shrink)

This article explores the networking activities of Count Nikolai Rumiantsev and Adam von Krusenstern, his close collaborator. The visionary Russian statesman and the celebrated navigator were deeply involved in northern exploration. They funded and organized a circumnavigating voyage by the brigRurikin 1815–18, with the explicit goals of searching for a northern passage between Eurasia and North America and conducting a series of scientific investigations in the Bering Strait region. This private exploratory enterprise profoundly influenced the exchange of information and (...) reconfigured both local and global networks of knowledge. Based on an analysis of private correspondence, printed accounts and journal articles related to theRurik's expedition, this study sheds light on how this transnational network of actors emerged and functioned, and how it promoted a lively circulation of information about exploration in the Bering Strait region in the 1810s–1820s. I argue that a complex interplay of geopolitical and intellectual competition, with exchanges, collaborations and coordination among various actors (e.g. patrons, navigators, scholars, entrepreneurs and publishers), stimulated further research on the global ocean's northern spaces and laid the foundations of marine science.

We examine recent work in cognitive neuroscience that investigates brain networks. Brain networks are characterized by the ways in which brain regions are functionally and anatomically connected to one another. Cognitive neuroscientists use various noninvasive techniques (e.g., fMRI) to investigate these networks. They represent them formally as graphs. And they use various graph theoretic techniques to analyze them further. We distinguish between knowledge of the graph theoretic structure of such networks (structural knowledge) and knowledge of what (...) instantiates that structure (nonstructural knowledge). And we argue that this work provides structural knowledge of brain networks. We explore the significance of this conclusion for the scientific realism debate. We argue that our conclusion should not be understood as an instance of a global structural realist claim regarding the structure of the unobservable part of the world, but instead, as a local structural realist attitude towards brain networks in particular. And we argue that various local approaches to the realism debate, i.e., approaches that restrict realist commitments to particular theories and/or entities, are problematic insofar as they don't allow for the possibility of such a local structural realist attitude.

I argue that one good reason for Scientific Realists to be interested in correspondence theories is the hope they offer us of being able to state and defend realistic theses in the face of well-known difficulties about modern physics: such theses as, that our theories are approximately true, or that they will tend to approach the truth. I go on to claim that this hope is unlikely to be fulfilled. I suggest that Realism can still survive in the (...) face of these difficulties, as a claim about the kind of theories we want to aim for. I relate this conception of Realism to various contemporary discussions, both by realists and antirealists. (shrink)

Aiming to improve the commercialization efficiency of scientific innovative achievements, this paper utilizes the time series visualization method to construct the time series network of each subsystem. After that, the network similarity is calculated by the cosine similarity theorem. On this basis, a new multilayer network adjacency matrix is obtained. With the adoption of k-core technology, the critical nodes can be identified to study the transformation efficiency of the innovation value in the network. Finally, according to the provincial innovation (...) value transformation data of China from 1998 to 2016, an empirical study was carried out to calculate and analyze the transformation efficiency of innovation achievements in 30 provinces. The results indicate that the transformation efficiency of innovation value can be expressed by the structure of the time series network constructed by the input-output vectors; the mapping relationship of the value transformation vectors could be reflected by the cosine similarity of the time series network, while the transformation efficiency of innovation value could be identified using the k-core; and the transformation efficiency of innovation value in three coastal provinces is relatively higher, while that of the rest of the provinces is roughly the same among the 30 provinces.

Summary Since at least the time of Helmholtz, the process of visual perception has been regarded as a two-stage affair consisting of an initial sensory stage corresponding to the proximal stimulus and a subsequent cognitive stage corresponding to the distal object. This construction amounts to an awkward mind body dualism wherein part of perception is done by the body and the other part is done by the mind. Gestalt theory rejected both raw sensations and their cognitive interpretation, offering a single (...) unified perceptual process that responds to an extended pattern of stimulation. They proposed organizational rules that describe how objects arise from the indifferent retinal mosaic. The same grouping principles by which objects are segmented also function to segregate regions of uniform illumination. Lightness values can then be computed by comparing luminance values within each such framework of illumination, with no need for the mystical concept of taking the illumination into account.

Research programs regularly compete to achieve the same goal, such as the discovery of the structure of DNA or the construction of a TEA laser. The more the competing programs share information, the faster the goal is likely to be reached, to society’s benefit. But the “priority rule”-the scientific norm according to which the first program to reach the goal in question must receive all the credit for the achievement-provides a powerful disincentive for programs to share information. How, then, (...) is the clash between social and individual interest resolved in scientific practice? This chapter investigates what Robert Merton called science’s “communist” norm, which mandates universal sharing of knowledge, and uses mathematical models of discovery to argue that a communist regime may be on the whole advantageous and fair to all parties, and so might be implemented by a social contract that all scientists would be willing to sign.

En este artículo se presenta el guión de una conferencia que Roberto Lehmann-Nitsche, pocos años después de radicarse en la Argentina, desarrolló en 1901 acerca del folklore mapuche. La intervención se realizó a solicitud de la Deutschen Frauen Verein, una asociación de mujeres alemanas con sede en la ciudad de Buenos Aires, y abordó aspectos teóricos sobre esta disciplina, entonces en expansión, desde la perspectiva germana. Además, realizó una catalogación de los materiales empíricos documentados por este antropólogo durante los primeros (...) años de su residencia en el país. El texto original, hasta el momento inédito, se entrega en su versión en alemán y en traducción al español. En la presentación se proporciona un análisis que permite reconocer cómo en esta intervención se integran apreciaciones que Lehmann-Nitsche también sostuvo en posteriores publicaciones científicas y de divulgación por él realizadas. Como se sabe, su producción en el campo del folklore comprendió dos vertientes: por un lado, el folklore criollo y por otro, el devenido de arte verbal y tradiciones de los pueblos indígenas preexistentes, en especial textos correspondientes a géneros narrativos y adivinanzas en las lenguas propias y en castellano. En relación con este último aspecto, se retoman aportes de autores filiados en la tradición germana a fin de indicar afinidades y vínculos, con algunos americanistas que eran sus contemporáneos.

The interactive correspondence of art, science, and preservation supports the composition of a four-volume anonymous herbarium originally belonging first to the Venetian library of Ambassador Hurtado de Mendoza, and later endowed to the Royal Library of the Monastery-Palace of El Escorial. This planted knowledge consist­ed of artistic and scientific practices to preserve not only the plants dried and glued to recycled paper, but the association of those plants, with names, stories, and contexts in ways that attest to the (...) development of natural history and philosophy in sixteenth-century Italy and Spain. This article describes and analyzes the composition of the Hurtado herbarium, its provenance, and its place in the context of early modern European naturalism and botany. Finally, it considers problems of reading this collection, and possible solutions to better understand the herbarium in El Escorial as another piece of this network of dissemination of ethnobotanical knowledge in early modern Europe.

When the creationism issue rose to the surface in the late 1970s, an organized opposition to the creationist campaign came from an unexpected source. Local groups of rank and file evolution defenders, led by a retired biology teacher, organized a grassroots network of anti-creationism called the Committees of Correspondence. They basically approached the creationism issue as a political rather than a scientific problem and fought the battle on local fronts, where creationists were heavily engaged in legal campaigns to (...) include their ideas in the public schools. Grassroots anti-creationism was, however, eventually replaced by a centralized national operation with an educational emphasis. In this paper, I will document the development of this neglected part of the creation-evolution controversy and discuss related issues, namely the politics of science that became clearly visible in the course of evolutionists' disputes over anti-creation strategies.

In Natural Ethical Facts William Casebeer argues that we can articulate a fully naturalized ethical theory using concepts from evolutionary biology and cognitive science, and that we can study moral cognition just as we study other forms of cognition. His goal is to show that we have "softly fixed" human natures, that these natures are evolved, and that our lives go well or badly depending on how we satisfy the functional demands of these natures. Natural Ethical Facts is a comprehensive (...) examination of what a plausible moral science would look like.Casebeer begins by discussing the nature of ethics and the possible relationship between science and ethics. He then addresses David Hume's naturalistic fallacy and G. E. Moore's open-question argument, drawing on the work of John Dewey and W. V. O. Quine. He then proposes a functional account of ethics, offering corresponding biological and moral descriptions. Discussing in detail the neural correlates of moral cognition, he argues that neural networks can be used to model ethical function. He then discusses the impact his views of moral epistemology and ontology will have on traditional ethical theory and moral education, concluding that there is room for other moral theories as long as they take into consideration the functional aspect of ethics; the pragmatic neo-Aristotelian virtue theory he proposes thus serves as a moral "big tent." Finally, he addresses objections to ethical naturalism that may arise, and calls for a reconciliation of the sciences and the humanities. "Living well," Casebeer writes, "depends upon reweaving our ethical theories into the warp and woof of our scientific heritage, attending to the myriad consequences such a project will have for the way we live our lives and the manner in which we structure our collective moral institutions.".

Al-Mu'jam Al-muḫtaṣ of Murtadā Al-Zabīdī (d. 1205/1791) in which a scholar recorded his teachers, the books that he obtained the right to narrate during his education life and the chain of transmission from his teachers to the author, is one of the important representatives of the mu'jam genres in 12th/18th century. It can be said that the mu'jam that Zabīdī wrote to record the important people in his life, goes beyond the standard mu'jam with its compilation style, sources, diversity of (...) biographers and anecdotes about the writing activity of the period. Based on Zabīdī's teachers, students and contemporaries, their origins, specialization and profession, the dates of their deaths, the dates of his encounters with them, the extent of his friendships, the dated rihle route, the lecture places and the books he taught, a panorama about the mu'jam will be drawn. The mu’jam, which includes 635 biographies, has a wide range of written and oral sources, especially ijazat and samā sources. Zabīdī's correspondence with scholars from different regions, taqrīz/appreciation written for his famous books and poems belonging to scholars of the period are among these sources. Numerous taqrīzs on his Tāj al-ʿArūs and Sharḥ Al-Iḥyā's point to their fame at that time, while Mu’jam, which has the appearance of an independent poetry anthology due to the poems that reach tens of pages, reveals his unknown poetic side. On the other hand, some couplets recorded in Persian and Turkish show his knowledge of these languages. Zabīdī is a versatile personality who lived in different geographies such as India, Yemen and Egypt and met many scholars there. Rihles in different regions of Yemen such as Zabid, Moravıa and Mocha, as well as inside Egypt, including Damietta, Raşıt, Fuwwah and Asyut, show that Zabīdī traveled frequently for the sake of knowledge. Egypt, where he went in 1167 (1753) with the advice of his teacher al-Aydarūs and spent thirty-eight years of his life, has an important place in his scientific adventure. Recording sufis, merchants and janitors as well as famous people from different fields such as poets, jurists and muhaddis in biographies reflects Zabīdī's extensive contact reaching various segments of society through the aforementioned rihles. While Zabīdī was obtaining knowledge through both these journeys and ijazat, he also gave ratification/ijazat to the students who came to him. While he prefers ijazat of al-musalsal bil awwaliyyah and Al-Awail Ṣaḥīḥ/al-Kutub al-Sittah for those who come to him for short periods of time on the occasion of pilgrimage, but on the other hand he gaves ijazat of Ṣaḥīḥ al-Bukhari, Shamail Tirmidhi, Sharḥ Al-Iḥyā and Al-Amali for his long-term students. Lessons, both open to the public in mosques and with more private groups at home, were held in informal rather than systematic/formal style like in the madrasah. The books that Zabīdī received the right to transmit through his rihles are listed below under the "textbooks" heading. When a book is mentioned in whichever biography, it can be implicitly considered the person has the elevated chain of transmission of the book. Similarly, it can be revealed in which region and by whom tranmits the short chain of a book. This reveals the unknown aspects of regional and temporal writing style. On the other hand, it is possible to find other traces of the background of writing and representation/taqrir through the mu'jam. For instance, a book was sometimes typed as a result of the students' compilation of lecture notes of their masters, sometimes when a person obtained a book he needed and he abbreviated important parts and copied a special copy for himself or a student could only get permission for giving lectures after he had written a book. The mu’jam includes besides of Zabīdī's books, the books written by the biographers in the form of "he has many books" or by mentioning the name directly. Even the recording of details such as the reason for writing, date and content information reveals the unknown aspects of the book writing style of the period. Ultimately, the importance of mu’jam, which was written as the result of a life spent with learning, although it is not well known in terms of genre; is to mention the biographical information collected from many different secondary sources, compiled as a result of long effort, such as history and tabaqat-tarajim about the scientific life of the author together with their evidences. Therefore, these kinds of books, that are mostly written by the author himself or his close student, in which the teacher constitutes its main element, is a primary source in the determination of the biographical information of the author, as well as the book and isnad, deserve to be examined separately because of their potential to shed light on the unknown aspects of the hadith history and literature of the later period.

This article examines the communication networks within and between science and technology studies (STS) and the history of science. In particular, journal relatedness data are used to analyze some of the structural features of their disciplinary identities and relationships. The results first show that, although the history of science is more than half a century older than STS, the size of the STS network is more than twice that of the history of science network. Further, while a majority of (...) the journals in the STS network are connected by weak ties, about half of the history of science network consists of strong ties. The history of science network is thus more cohesive than the STS network. The relatively strong cohesion within the history of science network is associated with comparatively high degrees of intra-disciplinary communication, but comparatively weak ties to only a few related disciplines. The analysis also shows that very few members of the history of science cliques are situated on the shortest path between both specialties. Moreover, given the relatively impermeable nature of the history of science network, the latter partially depends on STS to reach some of the neighboring disciplines. (shrink)
