AbstractBy shaping where individuals move, habitat configuration can fundamentally structure animal populations. Yet, we currently lack a framework for generating quantitative predictions about the role of habitat configuration in modulating population outcomes. For example, it is well known that the social structure of animal populations can shape spreading dynamics, but it remains underexplored to what extent such dynamics are determined by the underlying habitat configuration. To address this gap, we propose a framework and model inspired by studies using networks to characterize habitat connectivity. We first define animal habitat networks, explain how they can integrate information about the different configurational features of animals’ habitats, and highlight the need for a bottom-up generative model that can depict realistic variations in habitat structural connectivity. Second, we describe a model for simulating animal habitat networks (available in the R package AnimalHabitatNetwork), and demonstrate its ability to generate alternative habitat configurations based on empirical data, which forms the basis for exploring the consequences of alternative habitat structures. Finally, we use our framework to demonstrate how transmission properties, such as the spread of a pathogen, can be impacted by both local connectivity and landscape-level characteristics of the habitat. Our study highlights the importance of considering the underlying habitat configuration in studies linking social structure with population-level outcomes.

Yet, we currently lack a framework for generating quantitative predictions about the role of habitat configuration in modulating population outcomes. To address this gap, we propose a modelling framework inspired by studies using networks to characterize habitat connectivity. We first define animal habitat networks, explain how they can integrate information about the different configurational features of animal habitats, and highlight the need for a bottom–up generative model that can depict realistic variations in habitat potential connectivity. Second, we describe a model for simulating animal habitat networks (available in the R package AnimalHabitatNetwork), and demonstrate its ability to generate alternative habitat configurations based on empirical data, which forms the basis for exploring the consequences of alternative habitat structures. Finally, we lay out three key research questions and demonstrate how our framework can address them. By simulating the spread of a pathogen within a population, we show how transmission properties can be impacted by both local potential connectivity and landscape-level characteristics of habitats. Our study highlights the importance of considering the underlying habitat configuration in studies linking social structure with population-level outcomes.

ABSTRACTSocial structure can have profound evolutionary and ecological implications for animal populations. Structure can arise and be maintained via social preferences or be indirectly shaped by habitat structure. Understanding how social structure emerges is important for understanding the potential links between social structure and evolutionary and ecological processes. Here, we study a large community of wild birds fitted with uniquely-coded passive integrated transponder (PIT) tags and recorded on a grid of automated feeders fitted with radio frequency identification (RFID) antennae. We show that both large-scale and fine-scale network communities are consistent across years in this population, despite high generational turn-over. Studying the process that generates community structure, here the movement of individual birds across the woodland, suggests an important role of habitat geometry in shaping population-level social community structure. Our study highlights how relatively simple factors can produce apparent emergent social structure at the population scale, which has widespread implications for understanding eco-evolutionary dynamics.

Research Questions

One of the profound questions that troubled many philosophers is– “Who am I?” where do I come from? ‘Why am I, where I am? Or “How I see myself?” and maybe more technically -What is my subjectivity? How my subjectivity is formed and transformed? My attempt, in this paper, is to look at “I”, and see how it got shaped. To understand self, this paper tries to show, how subjectivity got transformed or persisted over five generations with changing social structure and institutions. In other words, I am trying to explore self-identity. I have analyzed changing subjectivity patterns of family, and its connection with globalization. Moreover, the research tries to show the role of the Meta field in search of subjectivity based on the following research questions; how my ancestor’s subjectivity changed with social fields? Which power forced them to change their citizenship? And how my identity is shaped within the metafield? The methodology of my study is qualitative. Faced to face interview is taken with the oldest member of family and relatives. The finding of my research is the subjectivity of Namita Poudel (Me) is shaped by the meta field, my position, and practices in the social field.

We analyze the governance structure of online stolen data markets. As cybercriminal underground economies, stolen data markets are beyond the reach of state intervention, and yet they need form and regulation in order to function. While the illicit nature of the business brings risks to its participants, the online characteristics of these markets enable the participants to communicate easily, which is a crucial means of generating trust. We first identify stolen data markets in terms of their economic organization as two-sided markets, economic platforms with two distinct user groups that provide each other with network synergies. This characterization enables us to understand the role of the forum administrator as that of an intermediary, market creator, and market regulator. Then we clarify the role of communication networks and social structure in creating trust among buyers and sellers.

Despite growing strength in recent decades, an archaeology of childhood has often been overlooked by those studying prehistory. This is concerning because communities are enlivened by their children, and conversations with and about children often provide a critical arena for the discussion of aspects of societies which prehistorians are comfortable addressing, such as social structure, identity and personhood. Through an exploration of childhood as expressed in the Earlier Bronze Age burials from Ireland, this article demonstrates that neither written sources, artistic depictions nor toys are necessary to speak of children in the past. Indeed, an approach which tacks between scales reveals subtle trends in the treatment of children which speak to wider shared concerns and allows a reflection on the role of children in prehistory.

The anarchic hand syndrome refers to an inability to control the movements of one’s own hand, which acts as if it has a will of its own. The symptoms may differ depending on whether the brain lesion is anterior, posterior, callosal or subcortical, but the relative classifications are not conclusive. This study investigates the role of white matter disconnections in a patient whose symptoms are inconsistent with the mapping of the lesion site. A repeated neuropsychological investigation was associated with a review of the literature on the topic to identify the frequency of various different symptoms relating to this syndrome. Furthermore, an analysis of the neuroimaging regarding structural connectivity allowed us to investigate the grey matter lesions and white matter disconnections. The results indicated that some of the patient’s symptoms were associated with structures that, although not directly damaged, were dysfunctional due to a disconnection in their networks. This suggests that the anarchic hand may be considered as a disconnection syndrome involving the integration of multiple antero-posterior, insular and interhemispheric networks. In order to comprehend this rare syndrome better, the clinical and neuroimaging data need to be integrated with the clinical reports available in the literature on this topic.

Abstract Background Network-based analysis of gene expression through co-expression networks can be used to investigate modular relationships occurring between genes performing different biological functions. An extended description of each of the network modules is therefore a critical step to understand the underlying processes contributing to a disease or a phenotype. Biological integration, topology study and conditions comparison (e.g. wild vs mutant) are the main methods to do so, but to date no tool combines them all into a single pipeline. Results Here we present GWENA, a new R package that integrates gene co-expression network construction and whole characterization of the detected modules through gene set enrichment, phenotypic association, hub genes detection, topological metric computation, and differential co-expression. To demonstrate its performance, we applied GWENA on two skeletal muscle datasets from young and old patients of GTEx study. Remarkably, we prioritized a gene whose involvement was unknown in the muscle development and growth. Moreover, new insights on the variations in patterns of co-expression were identified. The known phenomena of connectivity loss associated with aging was found coupled to a global reorganization of the relationships leading to expression of known aging related functions. Conclusion GWENA is an R package available through Bioconductor (https://bioconductor.org/packages/release/bioc/html/GWENA.html) that has been developed to perform extended analysis of gene co-expression networks. Thanks to biological and topological information as well as differential co-expression, the package helps to dissect the role of genes relationships in diseases conditions or targeted phenotypes. GWENA goes beyond existing packages that perform co-expression analysis by including new tools to fully characterize modules, such as differential co-expression, additional enrichment databases, and network visualization.

The Banias of eighteenth-century Surat, whom Michelguglielmo Torri earlier treated with indifference if not innocence, have invited his wrath since they were brought into focus by the publication of my essay on the Banias and the Surat riot of 1795. In his ‘rejoinder’ to my article, he seeks to wish away their existence altogether (to him there was no specific Bania community, the term merely signifying traders of all communities engaged in the profession of brokerage), and seeks to provide what he regards as an ‘alternative’ explanation of the Muslim–Bania riot of 1795. the Muslim-Bania riot of 1795. It shall be my purpose in this reply to show that his alternative explanation is neither an alternative nor even an explanation, and is based on a basic confusion in his mind about the Banias as well as the principal sources of tension in the social structure of Surat. I shall treat two main subjects in this reply to his misdirected criticisms. First, I shall present some original indigenous material as well as European documentation to further clarify the identity, position and role of the Banias, whom Irfan Habib in a recent article has identified as the most important trading group in the trading world of seventeenth and eighteenth-century India. It is also my purpose to show how the social order of Surat operated under stress by presenting some archival material, the existence of which Torri seems to be completely unaware of, on the Parsi-Muslim riot of 1788.
