Language and Letters of the Bluestocking Network : Sociolinguistic Issues in Eighteenth Century Epistolary English

This study deals with language change and variation in the correspondence of the eighteenth-century Bluestocking circle, a social network which provided learned men and women with an informal environment for the pursuit of scholarly entertainment. Elizabeth Montagu (1718 1800), a notable social hostess and a Shakespearean scholar, was one of their key figures. The study presents the reconstruction of Elizabeth Montagu s social networks from her youth to her later years with a special focus on the Bluestocking circle, and linguistic research on private correspondence between Montagu and her Bluestocking friends and family members between the years 1738 1778. The epistolary language use is investigated using the methods and frameworks of corpus linguistics, historical sociolinguistics, and social network analysis. The approach is diachronic and concerns real-time language change. The research is based on a selection of manuscript letters which I have edited and compiled into an electronic corpus (Bluestocking Corpus). I have also devised a network strength scale in order to quantify the strength of network ties and to compare the results of the linguistic research with the network analysis. The studies range from the reconstruction and analysis of Elizabeth Montagu s most prominent social networks to the analysis of changing morphosyntactic features and spelling variation in Montagu s and her network members correspondence. The linguistic studies look at the use of the progressive construction, preposition stranding and pied piping, and spelling variation in terms of preterite and past participle endings in the regular paradigm (-ed, - d, -d, - t, -t) and full / contracted spellings of auxiliary verbs. The results are analysed in terms of social network membership, sociolinguistic variables of the correspondents, and, when relevant, aspects of eighteenth-century linguistic prescriptivism. The studies showed a slight diachronic increase in the use of the progressive, a significant decrease of the stigmatised preposition stranding and increase of pied piping, and relatively informal but socially controlled epistolary spelling. Certain significant changes in Elizabeth Montagu s language use over the years could be attributed to her increasingly prominent social standing and the changes in her social networks, and the strength of ties correlated strongly with the use of the progressive in the Bluestocking Corpus. Gender, social rank, and register in terms of kinship/friendship had a significant influence in language use, and an effect of prescriptivism could also be detected. Elizabeth Montagu s network ties resulted in language variation in terms of network membership, her own position in a given network, and the social factors that controlled eighteenth-century interaction. When all the network ties are strong, linguistic variation seems to be essentially linked to the social variables of the informants.

Collaboration on social network sites: Amateurs, professionals and celebrities

Amateurs are found in arts, sports, or entertainment, where they are linked with professional counterparts and inspired by celebrities. Despite the growing number of CSCW studies in amateur and professional domains, little is known about how technologies facilitate collaboration between these groups. Drawing from a 1.5-year field study in the domain of bodybuilding, this paper describes the collaboration between and within amateurs, professionals, and celebrities on social network sites. Social network sites help individuals to improve their performance in competitions, extend their support network, and gain recognition for their achievements. The findings show that amateurs benefit the most from online collaboration, whereas collaboration shifts from social network sites to offline settings as individuals develop further in their professional careers. This shift from online to offline settings constitutes a novel finding, which extends previous work on social network sites that has looked at groups of amateurs and professionals in isolation. As a contribution to practice, we highlight design factors that address this shift to offline settings and foster collaboration between and within groups.

The social marketing theory-based (SMT) approach for designing interventions

- Purpose Despite the importance of theory as a driving framework, many social marketers either fail to explicitly use theory as the basis of designing social marketing interventions or default to familiar theories which may not accurately reflect the nature of the behavioural issue. The purpose of this paper is therefore to propose and demonstrate the social marketing theory (SMT)-based approach for designing social marketing interventions, campaigns or tools. - Design/methodology/approach This conceptual paper proposes a four-step process and illustrates this process by applying the SMT-based approach to the digital component of a social marketing intervention for preventing domestic violence. - Findings For effective social marketing interventions, the underpinning theory must reflect consumer insights and key behavioural drivers and be used explicitly in the design process. - Practical implications Social marketing practitioners do not always understand how to use theory in the design of interventions, campaigns or tools, and scholars do not always understand how to translate theories into practice. This paper outlines a process and illustrates how theory can be selected and applied. - Originality/value This paper proposes a process for theory selection and use in a social marketing context.

Uplink Power Control and Base Station Association in Multichannel Cellular Networks

A combined base station association and power control problem is studied for the uplink of multichannel multicell cellular networks, in which each channel is used by exactly one cell (i.e., base station). A distributed association and power update algorithm is proposed and shown to converge to a Nash equilibrium of a noncooperative game. We consider network models with discrete mobiles (yielding an atomic congestion game), as well as a continuum of mobiles (yielding a population game). We find that the equilibria need not be Pareto efficient, nor need they be system optimal. To address the lack of system optimality, we propose pricing mechanisms. It is shown that these mechanisms can be implemented in a distributed fashion.

Networks, Organisations and Men: Concepts and Interrelations

Research on men’s networks and homosociality in and around organisations can produce knowledge on organisational power relations, and contribute to the efforts to promote equality in working life. The search for a conceptual framework to study these issues arises in this paper from my ongoing work on men's social networks and gendered power in and around organisations. Men give each other social support through networks in which formal and informal relationships intermingle, but networks are also contexts of competition and oppression, and of construction of masculinities that are in hierarchical relations with each other and with femininities. For studying the networks men have with each other in work organisations I suggest a broader starting point that contextualises these homosocial networks with men’s other personal relations, and integrates different perspectives deriving from social network analysis, critical studies on men and organisational studies.

Probing the Allosteric Mechanism in Pyrrolysyl-tRNA Synthetase Using Energy-Weighted Network Formalism

Pyrrolysyl-tRNA synthetase (PyIRS) is an atypical enzyme responsible for charging tRNA(Pyl) with pyrrolysine, despite lacking precise tRNA anticodon recognition. This dimeric protein exhibits allosteric regulation of function, like any other tRNA synthetases. In this study we examine the paths of allosteric communication at the atomic level, through energy-weighted networks of Desulfitobacterium hafniense PyIRS (DhPyIRS) and its complexes with tRNA(Pyl) and activated pyrrolysine. We performed molecular dynamics simulations of the structures of these complexes to obtain an ensemble conformation-population perspective. Weighted graph parameters relevant to identifying key players and ties in the context of social networks such as edge/node betweenness, closeness index, and the concept of funneling are explored in identifying key residues and interactions leading to shortest paths of communication in the structure networks of DhPylRS. Further, the changes in the status of important residues and connections and the costs of communication due to ligand induced perturbations are evaluated. The optimal, suboptimal, and preexisting paths are also investigated. Many of these parameters have exhibited an enhanced asymmetry between the two subunits of the dimeric protein, especially in the pretransfer complex, leading us to conclude that encoding of function goes beyond the sequence/structure of proteins. The local and global perturbations mediated by appropriate ligands and their influence on the equilibrium ensemble of conformations also have a significant role to play in the functioning of proteins. Taking a comprehensive view of these observations, we propose that the origin of many functional aspects (allostery rand half-sites reactivity in the case of DhPyIRS) lies in subtle rearrangements of interactions and dynamics at a global level.

Forming Networks of Strategic Agents with Desired Topologies

Many networks such as social networks and organizational networks in global companies consist of self-interested agents. The topology of these networks often plays a crucial role in important tasks such as information diffusion and information extraction. Consequently, growing a stable network having a certain topology is of interest. Motivated by this, we study the following important problem: given a certain desired network topology, under what conditions would best response (link addition/deletion) strategies played by self-interested agents lead to formation of a stable network having that topology. We study this interesting reverse engineering problem by proposing a natural model of recursive network formation and a utility model that captures many key features. Based on this model, we analyze relevant network topologies and derive a set of sufficient conditions under which these topologies emerge as pairwise stable networks, wherein no node wants to delete any of its links and no two nodes would want to create a link between them.

Threats and trade-fffs in resource critical crowdsourcing tasks over networks

In recent times, crowdsourcing over social networks has emerged as an active tool for complex task execution. In this paper, we address the problem faced by a planner to incen-tivize agents in the network to execute a task and also help in recruiting other agents for this purpose. We study this mecha-nism design problem under two natural resource optimization settings: (1) cost critical tasks, where the planner’s goal is to minimize the total cost, and (2) time critical tasks, where the goal is to minimize the total time elapsed before the task is executed. We define a set of fairness properties that should beideally satisfied by a crowdsourcing mechanism. We prove that no mechanism can satisfy all these properties simultane-ously. We relax some of these properties and define their ap-proximate counterparts. Under appropriate approximate fair-ness criteria, we obtain a non-trivial family of payment mech-anisms. Moreover, we provide precise characterizations of cost critical and time critical mechanisms.

Protein Structure and Function: Looking through the Network of Side-Chain Interactions

Network theory has become an excellent method of choice through which biological data are smoothly integrated to gain insights into complex biological problems. Understanding protein structure, folding, and function has been an important problem, which is being extensively investigated by the network approach. Since the sequence uniquely determines the structure, this review focuses on the networks of non-covalently connected amino acid side chains in proteins. Questions in structural biology are addressed within the framework of such a formalism. While general applications are mentioned in this review, challenging problems which have demanded the attention of scientific community for a long time, such as allostery and protein folding, are considered in greater detail. Our aim has been to explore these important problems through the eyes of networks. Various methods of constructing protein structure networks (PSN) are consolidated. They include the methods based on geometry, edges weighted by different schemes, and also bipartite network of protein-nucleic acid complexes. A number of network metrics that elegantly capture the general features as well as specific features related to phenomena, such as allostery and protein model validation, are described. Additionally, an integration of network theory with ensembles of equilibrium structures of a single protein or that of a large number of structures from the data bank has been presented to perceive complex phenomena from network perspective. Finally, we discuss briefly the capabilities, limitations, and the scope for further explorations of protein structure networks.

Literatura boa é que eu gosto; ruim a que eu não gosto: fóruns de discussão literária da rede social ORKUT e a Teoria da Valoração uma análise crítica

Esta dissertação se insere nos estudos de Linguística e é vinculada à Análise Crítica do Discurso (FAIRCLOUGH, 1989, 2003) e à Linguística Sistêmico-Funcional (HALLIDAY, 1970, 1973), investigando o que é a qualidade literária para os internautas que interagem em fóruns de discussão do Orkut, à luz da Teoria da Valoração (MARTIN ; WHITE, 2005). De acordo com as categorias que abrangem o subsistema da Atitude da Teoria da Valoração (MARTIN ; WHITE, 2005), analisa-se como os leitores internautas se posicionam sobre a questão da qualidade literária e a ideologia que perpassa seus discursos. O conceito de ideologia adotado é o proposto por Thompson (2009), para quem o conceito deve ser compreendido a partir da noção de hegemonia e poder, ou seja, a ideologia necessariamente estabelece e sustenta relações de dominação, reproduzindo a ordem social que favorece indivíduos e grupos dominantes.O corpus desta pesquisa é composto de três amostras colhidas entre 15/07/2009 e 05/01/2010 correspondentes a uma discussão iniciada em comunidade relacionada a assuntos literários. A AMOSTRA 1 refere-se ao tópico Leitura difícil é sinal de qualidade?, da comunidade Literatura; a AMOSTRA 2, se refere ao tópico Qualidade do texto literário, da comunidade Discutindo... literatura e, por fim, a AMOSTRA 3 representa o tópico O que é um bom texto literário para você, também da comunidade Literatura. Cada discussão possui congruências e divergências quanto às representações sobre literatura e essas foram também analisadas. Não obstante, o que nos interessa é perceber como as ideologias perpassam seus discursos de acordo com os valores que os internautas atribuem a aspectos do texto literário. Foram escolhidos fóruns de discussão online do Orkut porque as interações em redes sociais constituem elemento novo das práticas sociais e, portanto, relevantes pontos de apoio para a investigação da criação de sentidos sobre o conceito de boa literatura. Investigar como a literatura, objeto de estudo acadêmico, é analisada em tais espaços cibernéticos é instigante, por não ser usual. Os resultados obtidos nessa pesquisa sugerem que o internauta reproduz o discurso acadêmico hegemônico acerca da qualidade literária ao debater a qualidade intrínseca do texto literário com a ressalva de manifestar seu contentamento ou descontentamento acerca de determinados textos literários e escritores, dado novo que revela uma característica deste espaço não institucional de discussão, em que os internautas se sentem à vontade para manifestar sua opinião

Entre duas rodas e uma tela:a sociabilidade na rede social Tornadeiros

A partir do entendimento das novas possibilidades sociais permitidas pela Internet, este trabalho tem por objetivo investigar a sociabilidade em redes sociais virtuais a partir do desenvolvimento do capital social entre os membros integrantes destas redes. Buscamos compreender as motivações que possibilitam que as relações sociais sejam construídas e mantidas no e a partir do espaço virtual determinando os fatores que tornam tais relações materializadas no espaço offline. Para tal, realizamos um estudo de caso de uma rede social constituída por motociclistas, o site Tornadeiros. Logramos apreender, o contexto de interação entre os membros desta rede e de que modo o fortalecimento do capital social é propulsor do deslocamento das relações no ambiente virtual para o espaço urbano, determinando a sedimentação de vínculos afetivos entre os indivíduos, inicialmente previstos como banais e efêmeros, dado a lacuna espaço-temporal existente entre estes atores. Para explorar estas dimensões iniciamos o trabalho etnográfico no ciberespaço e posteriormente no espaço urbano. A etnografia no ciberespaço consistiu na aplicação de um questionário online para determinar o perfil dos membros da rede social e na compilação de todo conteúdo de postagens disponível na memória coletiva do site. Os dados compilados foram tratados posteriormente para determinar a topologia da rede de interações entre os membros. Deste material, selecionamos 17 discursos para estudo, articulando a análise dos discursos com as observações produzidas pelo grafo da rede de interações do site. Finalmente, no segundo momento etnográfico, nós confrontamos os resultados com as entrevistas presenciais, tornando possível perceber o estabelecimento e manutenção das relações sociais a partir do capital social desenvolvido nesta rede.
