Children tend to produce words earlier when they are connected to a variety of other words along the phonological and semantic dimensions. Though these semantic and phonological connectivity effects have been extensively documented, little is known about their underlying developmental mechanism. One possibility is that learning is driven by lexical network growth where highly connected words in the child's early lexicon enable learning of similar words. Another possibility is that learning is driven by highly connected words in the (...) external learning environment, instead of highly connected words in the early internal lexicon. The present study tests both scenarios systematically in both the phonological and semantic domains across 10 languages. We show that phonological and semantic connectivity in the learning environment drives growth in both production‐ and comprehension‐based vocabularies, even controlling for word frequency and length. This pattern of findings suggests a word learning process where children harness their statistical learning abilities to detect and learn highly connected words in the learning environment. (shrink)

Previous research studies of traffic networks are mainly based on planar networks and less considered the influence of multilayer networks, which illustrate and represent different appropriate urban traffic modes. Development of rail and road networks is inseparable from the development of a prosperous urban area; thus, research on multilayer networks has scientific potential and fulfils a real need. In this paper, a framework of complex network based integrated multilayer urban growth and optimisation model is proposed, to analyse the (...) complex relationships between the traffic network structure, the population growth, and the urban land-use. The innovation of this paper is the combination of the traffic complex multilayer networks and the “Four Step Model”. With the multiobjective, multilayer network coevolution and optimisation model, a more efficient traffic network layout was generated based on different land-use, population density, and travel speed scenarios. Then, this paper has proved that the proposed CNIMUGOM can save the traffic network construction investment, reduce the travel cost, make the urban traffic network more efficient, and decrease the total traffic flow amount. This research has connected the recent complex multilayer network related study and traditional urban economic model based study. The findings of the study afford to improve the current land-use and traffic integrated models and can provide traffic network planning suggestions for urban agglomeration development. (shrink)

We present statistical analyses of the large‐scale structure of 3 types of semantic networks: word associations, WordNet, and Roget's Thesaurus. We show that they have a small‐world structure, characterized by sparse connectivity, short average path lengths between words, and strong local clustering. In addition, the distributions of the number of connections follow power laws that indicate a scale‐free pattern of connectivity, with most nodes having relatively few connections joined together through a small number of hubs with many connections. These regularities (...) have also been found in certain other complex natural networks, such as the World Wide Web, but they are not consistent with many conventional models of semantic organization, based on inheritance hierarchies, arbitrarily structured networks, or high‐dimensional vector spaces. We propose that these structures reflect the mechanisms by which semantic networks grow. We describe a simple model for semantic growth, in which each new word or concept is connected to an existing network by differentiating the connectivity pattern of an existing node. This model generates appropriate small‐world statistics and power‐law connectivity distributions, and it also suggests one possible mechanistic basis for the effects of learning history variables (age of acquisition, usage frequency) on behavioral performance in semantic processing tasks.

The fate of new ventures incubated by the same corporate ecosystem is different. Can entrepreneurs’ ideas affect the way out of incubating companies? Based on self-verification theory and symbiosis theory, we took millennial entrepreneurs as the research object, combined with entrepreneurial enterprises’ data in the makerspace. We analyzed the impact of millennials’ entrepreneurial values on new ventures growth and explored the mediating role of entrepreneurial symbiosis networks. The following conclusions are obtained by analyzing the questionnaire of 191 millennial entrepreneurs: (...) Millennials’ entrepreneurial values significantly promote new ventures growth. The strength and scale of the entrepreneurial symbiosis network have a positive impact on new ventures growth. The entrepreneur symbiosis network acts as an intermediary between the millennials’ entrepreneurial values and new ventures growth. (shrink)

In his book The Value of Science Poincaré criticizes a certain view on the growth of mathematical knowledge: “The advance of science is not comparable to the changes of a city, where old edifices are pitilessly torn down to give place to new ones, but to the continuous evolution of zoological types which develop ceaselessly and end by becoming unrecognizable to the common sight, but where an expert eye finds always traces of the prior work of the centuries past” (...) (Poincaré 1958, p. 14). The view criticized by Poincaré corresponds to Frege’s idea that the development of mathematics can be described as an activity of system building, where each system is supposed to provide a complete representation for a certain mathematical field and must be pitilessly torn down whenever it fails to achieve such an aim. All facts concerning any mathematical field must be fully organized in a given system because “in mathematics we must always strive after a system that is complete in itself” (Frege 1979, p. 279). Frege is aware that systems introduce rigidity and are in conflict with the actual development of mathematics because “in history we have development; a system is static”, but he sticks to the view that “science only comes to fruition in a system” because “only through a system can we achieve complete clarity and order” (Frege 1979, p. 242). He even goes so far as saying that “no science can be so enveloped in obscurity as mathematics, if it fails to construct a system” (Frege 1979, p. 242). By ‘system’ Frege means ‘axiomatic system’. In his view, in mathematics we cannot rest content with the fact that “we are convinced of something, but we must strive to obtain a clear insight into the network of inferences that support our conviction”, that is, to find “what the primitive truths are”, because “only in this way can a system be constructed” (Frege 1979, p. 205). The primitive truths are the principles of the axiomatic system. Frege’s stress on the role of systems also determines his views on the growth of mathematical knowledge.. (shrink)

Because the kidney (metanephros) starts to function before completing development, its patterning and morphogenesis need to be closely integrated with its growth. This is achieved by blast cells at the kidney periphery generating new nephrons that link up to the extending collecting‐duct arborisation, while earlier‐formed and more internal nephrons are maturing and beginning to filter serum. This pattern of development requires that cell division and apoptosis be co‐ordinated in the various kidney compartments (collecting‐ducts, blast cells, metanephric mesenchyme, nephrons and (...) vascular system). The underlying regulatory networks for cell proliferation are beginning to be unravelled, mainly through expression studies, mutation analysis and experimentation in vitro. This article summarises current knowledge of kidney growth and apoptosis, and analyses some of the 80 or so ligand–receptor pairings that seem to sustain development and growth. It also points to some unanswered questions, the most intriguing being what role does apoptosis play during normal kidney development? BioEssays 24:72–82, 2002. © 2002 John Wiley & Sons, Inc.

The problem this article focuses on is not the isolated individual act of corruption, but the systematic, pervasive sub-system of corruption that can and has existed across historical periods, geographic areas, and political-economic systems. It is important to first understand how corrupt and unethical subsystems operate, particularly their network nature, in order to reform and change them while not becoming what we are trying to change. Twelve key system elements are considered that include case examples from Asia, Latin America, (...) the Mediterranean, and North America. A key operating feature of corruption sub-systems is that they are relatively stable networks rather than exceptional, independent, individual events. Drawing on social network, social movement, and action-learning theories, six theory building propositions concerning ethical corruption reform are developed. (shrink)

A protein kinase cascade is involved in the action of some mitogens. The cascade begins with receptor tyrosine kinase activation by growth factors. The resulting signal is transmitted into cells via phospholipid metabolism which produces a variety of second messengers and by intracellular protein kinase activation. The signal is then propagated and disseminated via a network of other proteln kinases and protein phosphatases. Recent research suggests that ribosomal protein S6 kinase and casein kinase II are two important elements (...) in the kinase cascade that leads to the initiation of growth. The nature and some properties of these hitherto lesser known enzymes is considered. (shrink)

In this paper I explore consciousness and intelligence in the setting of conventional neuroscience and cognitive science. To be conscious is to be aware but awareness is not always intelligence. Intelligence is task driven, and comes at a later stage in development than consciousness. Consciousness and intelligence are sometimes interdependent on each other, but have always been known as separate entities; an attempt to associate them, results in a lot of debate. This paper hypothesises the growth of consciousness to (...) be horizontal, while the growth of intelligence to be vertical during the progression of development. The horizontal growth of consciousness is completely dependent on cell division and cell differentiation, while the vertical growth of intelligence depends on the horizontal growth of consciousness and enhancement of neural systems. Consciousness is computed within the microtubular network of a single cell, which amplifies with multicellularity, while intelligence is related to the nervous system which matures with complexity.

Recent research shows that a faulty or sub‐optimally operating metabolic network can often be rescued by the targeted removal of enzyme‐coding genes – the exact opposite of what traditional gene therapy would suggest. Predictions go as far as to assert that certain gene knockouts can restore the growth of otherwise nonviable gene‐deficient cells. Many questions follow from this discovery: What are the underlying mechanisms? How generalizable is this effect? What are the potential applications? Here, I approach these questions (...) from the perspective of compensatory perturbations on networks. Relations are drawn between such synthetic rescues and naturally occurring cascades of reaction inactivation, as well as their analogs in physical and other biological networks. I specially discuss how rescue interactions can lead to the rational design of antagonistic drug combinations that select against resistance and how they can illuminate medical research on cancer, antibiotics, and metabolic diseases.

Cluster growth models are utilized for a wide range of scientific and engineering applications, including modeling epidemics and the dynamics of liquid propagation in porous media. Invasion percolation is a stochastic branching process in which a network of sites is getting occupied that leads to the formation of clusters. The occupation of sites is governed by their resistance distribution; the invasion annexes the sites with the least resistance. An iterative cluster growth model is considered for computing the (...) expected size and perimeter of the growing cluster. A necessary ingredient of the model is the description of the mean perimeter as the function of the cluster size. We propose such a relationship for the site square lattice. The proposed model exhibits the expected phase transition of percolation models, i.e., it diverges at the percolation threshold p c. We describe an application for the porosimetry percolation model. The calculations of the cluster growth model compare well with simulation results. (shrink)

This paper proposes a new financial market model based on the analysis of the minority game model. The agent in this model forms a network through information sharing, and the agent uses the minority game model to realize the evolution of the system. To better describe the financial market, we also adopt a prior connection strategy for the model. The network formed by the agent has the characteristics of a scale-free network, and as the initial network (...) connection probability increases, the growth rate of the corresponding agent’s average connection degree increases and then decreases after reaching the peak.

Embryonic development and adult tissue homeostasis are controlled through activation of intracellular signal transduction pathways by extracellular growth factors. In the past, signal transduction has largely been regarded as a linear process. However, more recent data from large‐scale and high‐throughput experiments indicate that there is extensive cross‐talk between individual signaling cascades leading to the notion of a signaling network. The behavior of such complex networks cannot be predicted by simple intuitive approaches but requires sophisticated models and computational simulations. (...) The purpose of such models is to generate experimentally testable hypotheses and to find explanations for unexpected experimental results. Here, we discuss the need for, and the future impact of, mathematical models for exploring signal transduction in different biological contexts such as for example development.

Although the rapid growth of digital data and computationally advanced methods in the social sciences has in many ways exacerbated tensions between the so-called ‘quantitative’ and ‘qualitative’ approaches, it has also been provocatively argued that the ubiquity of digital data, particularly online data, finally allows for the reconciliation of these two opposing research traditions. Indeed, a growing number of ‘qualitatively’ inclined researchers are beginning to use computational techniques in more critical, reflexive and hermeneutic ways. However, many of these claims (...) for ‘quali-quantitative’ methods hinge on a single technique: the network graph. Networks are relational, allow for the questioning of rigid categories and zooming from individual cases to patterns at the aggregate. While not refuting the use of networks in these studies, this paper argues that there must be other ways of doing quali-quantitative methods. We first consider a phenomenon which falls between quantitative and qualitative traditions but remains elusive to network graphs: the spread of information on Twitter. Through a case study of debates about nuclear power on Twitter, we develop a novel data visualisation called the modulation sequencer which depicts the spread of URLs over time and retains many of the key features of networks identified above. Finally, we reflect on the role of such tools for the project of quali-quantitative methods. (shrink)

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)

Financial crises have become an all-too-common occurrence over the past twenty years, largely as a result of changes in finance brought about by increasing internationalization and integration. As domestic financial systems and economies become more interlinked, weaknesses can significantly impact not only individual economies but also markets, financial intermediaries and economies around the world. This volume addresses the twin objectives of financial development in the context of financial stability and the role of law in supporting both. Financial stability (frequently seen (...) as the avoidance of financial crisis) has become an objective of the international financial architecture as well as individual economies and central banks. At the same time, financial development is now seen to play an important role in economic growth. In both financial stability and financial development, law and related institutions have a central role. (shrink)

This essay deals with technologies, techniques, business models and legal structures governing telecommunications infrastructures. Megacities are especially vulnerable to shifting agencies in telecoms provision. This paper addresses the relation of the economics of growth, built-in obsolescence and product life cycles with the complex determinations of telecommunications governance in relation to the physical environment of megacities. It argues that an ‘environmentalism of the poor’ must be integrated into considerations of both ecological critique and analyses of telecommunications infrastructure and business practice.

Functional near-infrared spectroscopy is a neuroimaging technique that has undergone tremendous growth over the last decade due to methodological advantages over other measures of brain activation. The action-observation network, a system of brain structures proposed to have “mirroring” abilities, has been studied in humans through neural measures such as fMRI and electroencephalogram ; however, limitations of these methods are problematic for AON paradigms. For this reason, fNIRS is proposed as a solution to investigating the AON in humans. The (...) present review article briefly summarizes previous neural findings in the AON and examines the state of AON research using fNIRS in adults. A total of 14 fNIRS articles are discussed, paying particular attention to methodological choices and considerations while summarizing the general findings to aid in developing better protocols to study the AON through fNIRS. Additionally, future directions of this work are discussed, specifically in relation to researching AON development and potential multimodal imaging applications. (shrink)

Digital companies exhibit discontinuous growth in the process of shifting from their existing core business to a newer and less familiar business. This pattern of growth often ends in failure mainly because companies invest most of their resources in maintaining the value network of their existing core business, which ultimately results in a “lock-in” effect. The fractal theory assumes that there are similarities among fractals within companies. These similarities may reduce the threats posed by the value (...) class='Hi'>network lock-in effect and increase the chances of successful discontinuous growth. In this study, we applied fractal theory to consider the following questions: in what aspects does the successful discontinuous growth of digital companies exhibit fractal characteristics? What strategy does digital companies use to ensure these fractal characteristics? We adopted an exploratory single-case study method and chose ByteDance as the case company to analyze its successful shift from Toutiao to Douyin. Our results show that a necessary condition for the successful discontinuous growth of digital companies is that similarities exist between the existing core business and the new business and entrepreneurial bricolage is a strategy used by digital companies to ensure the existence of fractal characteristics of similarities. We discuss the theoretical contributions and practical implications of this finding. (shrink)

All the conserved detailed results of evolution stored in DNA must be read, transcribed, and translated via an RNAmediated process. This is required for the development and growth of each individual cell. Thus, all known living organisms fundamentally depend on these RNA-mediated processes. In most cases, they are interconnected with other RNAs and their associated protein complexes and function in a strictly coordinated hierarchy of temporal and spatial steps (i.e., an RNA network). Clearly, all cellular life as we (...) know it could not function without these key agents of DNA replication, namely rRNA, tRNA, and mRNA. Thus, any definition of life that lacks RNA functions and their networks misses an essential requirement for RNA agents that inherently regulate and coordinate (communicate to) cells, tissues, organs, and organisms. The precellular evolution of RNAs occurred at the core of the emergence of cellular life and the question remained of how both precellular and cellular levels are interconnected historically and functionally. RNA-networks andRNA-communication can interconnect these levels.With the reemergence of virology in evolution, it became clear that communicating viruses and subviral infectious genetic parasites are bridging these two levels by invading, integrating, coadapting, exapting, and recombining constituent parts in host genomes for cellular requirements in gene regulation and coordination aims. Therefore, a 21st century understanding of life is of an inherently social process based on communicating RNA networks, in which viruses and cells continuously interact. (shrink)

In stakeholder theory, most research on cooperation has been focused on inter-organizational collaboration field centered at the dyadic level, excluding the relational or network data. Relational or network data are important as the firms do not simply respond to each stakeholder individually but to an interaction of influences from the entire stakeholder set. The purpose of this article is to analyze the cooperation process among the firm and its stakeholders by considering the relational data and to describe the (...) role of the firm in such cooperation processes. The empirical evidence is provided by an inductive in-depth case study on the company 'Gas-Nat' and its stakeholders cooperating on the 'natural gas pipeline program' in Argentina. To do so, I combined both quantitative sociometric data and qualitative data from grounded theory and ethnographic observations. This research suggests a stakeholder cooperation model based on structural and relational factors. The results indicate that stakeholder cooperation is not just determined by stakeholder position, but they can vary depending on the political opportunity structure in the network and on the framing process. It was found that network structure may create a context for selective cooperation but doesn't explicitly determine it which is different from the previous research in stakeholder network literature. The role of the firm in the cooperation process was found as a tertius iungens role which implies to join, unite, or connect, and it is different from the existing prominent network literature of tertius gaudens.

This paper proposes two interrelated arguments: first, it is argued that agro-commodity traders are uniquely placed at the crossroads of agricultural trade to benefit from agricultural commodity speculation; and second, that the networks constituting their operations are central to their hedging activities. The case of Cargill—the largest privately owned company in the United States and one of the largest agricultural traders in the world—is used to support this argument by unpacking its operations, structure, and hedging strategies. In order to connect (...) the operations of Cargill to its speculating strategies, this paper first traces how agriculture and finance have become increasingly intertwined leading to heightened agricultural commodity speculation. Second, Cargill will be positioned within this process by analyzing how it has financialized its own strategies and its Corporate Platform. Third, Black River Asset Management, Cargill’s private equity arm, will be analyzed to show how it uses the information moving through Cargill’s Platform to engage in hedging and/or speculation.

IntroductionDrug-related deaths are a major public health challenge. Losing a child to a DRD can be a very stressful life event, which places parents at risk of mental and physical health problems. However, traumatic experiences like losing a child to DRD can paradoxically also lead to positive psychological changes. A mixed-method approach was used to understand the complexity of the phenomenon of post-traumatic growth experienced by parents following a DRD.MethodBy combining data from a survey and interviews, we explored positive (...) growth experiences among Norwegian parents. We conducted descriptive analyses of the sample’s demographic characteristics and mean scores for Post-traumatic Growth Inventory items. Hierarchical multiple regression was used to examine the influence of the ability to perform daily activities, self-efficacy, social support, and symptoms of prolonged grief on the outcome variable of post-traumatic growth. Reflexive thematic analysis was applied to analyze the qualitative data. Finally, we integrated the results of the survey and the interviews.ResultsFor items measuring post-traumatic growth, parents scored highest on the item “I discovered that I’m stronger than I thought I was” and lowest on the item “I am able to do better things with my life.” Self-efficacy and social support had a statistically significant relation with post-traumatic growth. Two themes were generated from the interviews: new perspectives on life and new paths in life. Even though the “New Possibilities” subscale had the lowest mean score for the PTGI-SF, new paths in life were important for many of the interviewed parents.DiscussionParents described traumatic stressors associated with having a child who uses narcotics and hence experienced positive changes even before losing their child. We argue that on an individual level, the consequences of spillover stigma, low self-efficacy, and intrusive rumination can hinder potential post-traumatic growth. On a group level, enhancing network support may increase post-traumatic growth experiences. Hence, parents who have experienced a DRD can benefit from help to activate their social networks and strengthen their self-efficacy. (shrink)

Roland Allen emerged as an independent missionary and theologian within the Anglican Mission to North China from 1895 to 1903. For the rest of his life, he continued as a freelance missiological writer, debater and priest for some time connected to the interdenominational World Dominion Press. As a theologian and churchman, with a genuine incarnational ecclesiology as his foundation, he combined a Catholic view of Anglicanism with a deliberate concern for local Christian initiatives and the spontaneous expansion of local Christian (...) communities within their own environment. Basic in his ecclesiology was his view of the Church as a sacramental body, a network of local fellowships celebrating the Sacraments. Therefore, these nurtured local Christian ‘Churches’ are to be regarded and treated as the proper agents of Evangelization. In order to implement this understanding of mission he encouraged experiments with ordination of local voluntary clergy to open up the access to a sacramental life, and, thereby, promoting growth and expansion in mission.

Human neoplasms develop following the progressive accumulation of genetic and epigenetic alterations to oncogenes and tumor suppressor genes. These alterations confer a growth advantage to the cancer cell, leading to its clonal proliferation, invasion into surrounding tissues, and spread to distant organs. Genes that are altered in neoplasia affect three major biologic pathways that normally regulate cell growth and tissue homeostasis: the cell cycle, apoptosis, and differentiation. While each of these pathways can be defined by a unique set (...) of molecular events, they are not biologically separate. Rather, they function more as an integrated molecular network, and perturbations in one pathway can have profound consequences on another. Insights into what distinguishes the regulation of growth and differentiation in a normal cell versus a cancer cell have led to the development of novel anticancer therapies.

The article discusses approaches to welfare under no-growth conditions and against the background of the growing significance of climate change as a socio-ecological issue. While most governments and scholars favor “green deal” solutions for tackling the climate crisis, a growing number of discussants are casting doubt on economic growth as the answer to it and have provided empirical evidence that the prospects for globally decoupling economic growth and carbon emissions are very low indeed. These doubts are supported (...) by recent contributions on happiness, well-being and alternative measures of measuring prosperity, which indicate that individual and social welfare is by no means equivalent to GDP growth. If the requirements of prosperity and welfare go well beyond material sustenance, then approaches that aim to conceptualize welfare under the circumstances of a “stable state economy” become more relevant. A qualitatively different environmental and welfare policy governance network would need to integrate the redistribution of carbon emissions, work, time, income and wealth. Since social policies will be necessary to address the emerging inequalities and conflicts, this article considers the roles that the various “no-growth” approaches dedicate to social policy and welfare instruments.

Global production networks connect multiple producers involved in fragmented manufacturing processes. Major brands and retailers, considered as lead firms, are under increasing pressure to ensure products made through GPNs are produced sustainably. Theories of governance developed to understand dynamics in outsourced production can provide insight into this issue. However, these theories and related empirical research have often focused on relationships between lead firms and upper-tier suppliers. When manufacturing involves multiple fragmented stages, understanding the role of lead firms becomes more difficult. (...) This article considers new governance roles that lead firms, as buyers, are playing when attempting to promote sustainable practices across all stages of production for buyer-driven industries. The focus is exploring the nature of new governance approaches which lead firms have developed in order to address diverse sustainability challenges found within GPNs, particularly related to lower-tier suppliers. These approaches can involve lead firms working through vertical buyer–seller links or developing new horizontal relationships, which link lead firms with lower-tier suppliers and governance processes in these suppliers’ local productive systems. The findings draw from field research examining how top UK garment retailers provide governance to producers involved in creating cotton garments in India and a review of publicised policies and practices of these retailers related to promoting sustainable production. Five types of governance mechanisms that can involve vertical or horizontal links are identified. Considering the growth of new governance relationships expands previous conceptions of the roles of lead firm governance. (shrink)

Working women in the Caribbean and Latin America are more active in the labor market than their counterparts in most other regions of the world. Yet, they remain much less economically mobile than working men. Using research from a long-term study in Martinique, this article offers a new view of the cross-class construction of women's economic immobility. Research results suggest that irrespective of a woman's socioeconomic status, household structure, education, skills, or freedom from domestic chores, the organization of her work (...) is patterned in ways that preclude economic growth. When women try to “get ahead,” they invest more of their own time; men, by contrast, put others to work. I argue that these and other gender-based patterns of work organization and network management express a hidden but enduring legacy of a patriarchal value system. (shrink)

This paper presents a sociological theoretical framework for the study of self-representation in social networks. Theoretically, the paper draws on the sociological classics of E. Goffman and M. Castells and work from other academic fields in which self-presentation and social networks have been explored as social phenomena. The first part of the paper provides a contextual framework for the development of information technology and the growth of social network users, and offers some terminological clarifications. Then, the sociological approaches (...) to the phenomena of social networks and self-representation are analysed within the framework of the dramaturgical approach. The spatiotemporal framework created by the emergence of the Internet is questioned, and self-representation is examined in this context. The notion of the exhibition site that defines the new form of appearance on social network platforms, the temporal status of the contemporary form of self-representation on social networks and the asynchronous character of communication implied by this self-representation are also analysed.

Despite the recent progress in the description of the molecular mechanisms of proliferation and differentiation controls in vitro, the regulation of the homeostasis of normal stratified epithelia remains unclear in vivo. Computer simulation represents a powerful tool to investigate the complex field of cell proliferation regulation networks. It provides huge computation capabilities to test, in a dynamic in silico context, hypotheses about the many pathways and feedback loops involved in cell growth and proliferation controls.Our approach combines a model of (...) cell proliferation and a spatial representation of cells in 2D using the Voronoi graph. The cell proliferation model includes intracellular (cyclins, Cyclin Dependent Kinases - CDKs, Retinoblastoma protein - Rb, CDK inhibitors) and extracellular controls (growth and differentiation factors, integrins). The Voronoi graph associates a polygon with every cell and the set of these polygons defines the tissue architecture. Thus, the model provides a quantitative model of extracellular signals and cell motility as a function of the neighborhood during time dependent simulations. (shrink)

SummaryIn 1684, during the Edo period (1603–1868), the imperial court of Japan passed a reform act that resulted in a new almanac called the Jôkyô almanac. This was the first reform in more than eight hundred years, and marked a departure from the past practice of adopting almanacs from China. Yet, the reform was complicated, and it was achieved after decades through the efforts of Shibukawa Harumi (1639–1715). How was the reform accomplished, and why was it significant? In this study, (...) I will focus on Harumi's role in the reform. I propose to examine the reform as the culmination of a process deeply linked to Harumi's political connections and his intellectual growth especially in the field of calendrical sciences. I will show that this approach of looking at the reform by analyzing different aspects of Harumi's life has implications for understanding trends in society in seventeenth-century Japan. First, despite the ban on Christianity, intellectuals like Harumi assimilated European sciences in unique ways. Second, Harumi's activities exemplified how intellectual ties were increasingly embedded within political networks. Overall, I will argue that the reform of the almanac, viewed as a process surrounding the core figure of Harumi, was driven by scientific goals and personal ambitions. (shrink)

Local food systems are growing, and little is known about how the constellation of farms and markets change over time. We trace the evolution of two local food systems over six years, including a dataset of over 2690 market connections between 1520 locations. Longitudinal social network analysis reveals how the architecture, actor network centrality, magnitude, and spatiality of these supply chains shifted during the 2012–2018 time period. Our findings demonstrate that, despite growth in the number of farmers’ (...) markets, grocery stores, farms and restaurants in both counties, each local food system also experienced high turnover rates. Over 80% of the market connections changed during the study period. Farms, farmers’ markets, and grocery stores showed a 40–50% ‘survival’ rate, indicating their role in sustaining local food systems over longer time periods. Other actors, such as restaurants, had a much higher turnover rate within the network. Both food systems became more close-knit and consolidated as the center of gravity for both local food systems pulled away from urban areas toward rural farmland. Evidence of both growth and decay within local food systems provides a new understanding of the social networks behind local food markets. (shrink)

As a criterion of a good firm, a lucrative and growing business has been said to be important. Recently, however, high profitability and high growth potential are insufficient for the criteria, because social influences exerted by recent firms have been extremely significant. In this paper, high social relationship is added to the list of the criteria. Empirical corporate social performance versus corporate financial performance (CSP–CFP) relationship studies that consider social relationship are very limited in Japan, and there are no (...) definite conclusions for the studies in the world, because of scant data and the inappropriate methods, especially for supporting linear hypothesis which these studies are based on. In this paper, the CSP–CFP relationship is analyzed by an artificial neural networks model, which can deal with a non-linear relationship, using 10-year follow-up survey data. (shrink)

In the modern scientific literature, there are many reports about the successful application of neural network technologies for solving complex applied problems, in particular, for modeling the urban real estate market. There are neural network models that can perform mass assessment of real estate objects taking into account their construction and operational characteristics. However, these models are static because they do not take into account the changing economic situation over time. Therefore, they quickly become outdated and need frequent (...) updates. In addition, if they are designed for a specific city, they are not suitable for other cities. On the other hand, there are several dynamic models taking into account the overall state of the economy and designed to predict and study the overall price situation in real estate markets. Such dynamic models are not intended for mass real estate appraisals. The aim of this article is to develop a methodology and create a complex model that has the properties of both static and dynamic models. Moreover, our comprehensive model should be suitable for evaluating real estate in many cities at once. This aim is achieved since our model is based on a neural network trained on examples considering both construction and operational characteristics, as well as geographical and environmental characteristics, along with time-changing macroeconomic parameters that describe the economic state of a specific region, country, and the world. A set of examples for training and testing the neural network were formed on the basis of statistical data of real estate markets in a number of Russian cities for the period from 2006 to 2020. Thus, many examples included the data relating to the periods of the economic calm for Russia, along with the periods of crisis, recovery, and growth of the Russian and global economy. Due to this, the model remains relevant with the changes of the international economic situation and it takes into account the specifics of regions. The model proved to be suitable for solving the following tasks: industrial economic analysis, company strategic and operational management, analytical and consulting support of investment, and construction activities of professional market participants. The model can also be used by government agencies authorized to conduct public cadastral assessment for calculating property taxes. (shrink)

The objective of our study is to capture the roles of product quality and network effects in the success and efficiency of network markets under strategic settings that defined in terms of market share as a strategic factor and profit as a financial indicator. The research paper shows that the efficiency of network markets depends heavily on the phase adjustment of competition models and the balance of network effects and product quality among enterprises. the network (...) market is always efficient in price competition, but not true in quantity competition when the network effect difference is sufficiently large or/and the quality difference is relatively small, then network effects may play a perverse role in market efficiency. The main findings reveal that network effects do not always enhance the role of quality in market efficiency and market growth. The research outcomes point to high quality enterprises’ attitude toward compatibility with enterprises with large network effects. This research paper also offers insights on government intervention to correct the distorted impacts of sufficiently large network effects on the efficiency of network markets. (shrink)

The majority of analyses investigating the professionalisation of scientific domains tend to assume the linear and general features of this transformation. These studies focus on the shift from a non-professionalised state to a professionalised state. This dual approach, however, crucially lacks some other aspects of the process of professionalisation. This issue is discussed within the context of the growth of prehistoric archaeology in France from the 1940s, by observing scientific societies, national research organisations and their social networks. Looking at (...) the scale of Georges Laplace’s career and that of his research group, which studied the typologie analytique method, this article demonstrates the benefits of a ternary model which also encompasses the modes of refusal of professionalisation.

The H19 gene produces a non‐coding RNA, which is abundantly expressed during embryonic development and down‐regulated after birth. Although this gene was discovered over 20 years ago, its function has remained unclear. Only recently a role was identified for the non‐coding RNA and/or its microRNA partner, first as a tumour suppressor gene in mice, then as a trans‐regulator of a group of co‐expressed genes belonging to the imprinted gene network that is likely to control foetal and early postnatal (...) class='Hi'>growth in mice. The mechanisms underlying this transcriptional or post‐transcriptional regulation remain to be discovered, perhaps by identifying the protein partners of the full‐length H19 RNA or the targets of the microRNA. This first in vivo evidence of a functional role for the H19 locus provides new insights into how genomic imprinting helps to control embryonic growth. (shrink)
