Orthodox Core-Heterodox Periphery? Contrasting Citation Networks of Economics Departments in Vienna

Glötzl, Florentin, Aigner, Ernest January 2018 (has links) (PDF)
The notion of an "orthodox core-heterodox periphery" structure and the extent of interdisciplinary links have been widely discussed, and partially investigated bibliometrically, within economic discourse. We extend this research by applying tools from social network analysis to citation data of three economics departments located in Vienna, two mainstream and one non-mainstream, to assess their relative citation patterns. We show that both mainstream economics departments follow the asserted core-periphery pattern and have a mono-disciplinary research focus, while the citation network of the non-mainstream department has a polycentric structure and is both more heterodox and interdisciplinary. These findings suggest that discussions about the future of heterodox economics should pay more attention to the organizational level and seek allies from other disciplines.

Análise de redes sociais para configuração do layout de trabalho visando a transferência de conhecimento

Bertoni, Vanessa Becker January 2016 (has links)
Os contextos em que as organizações operam e agem mudaram drasticamente nos últimos anos. Neste sentido, o espaço físico e a organização encontram-se conectados. As famosas palavras de Winston Churchill em 19431: “Nós moldamos nossos prédios e nossas construções nos moldam”, indiretamente já se referia à importância do espaço físico em relação a interação entre indivíduos. O design dos espaços de trabalho é normalmente guiado por topologias (formas de configurar layouts: aberto, fechado, celular) que descrevem e determinam a qualidade das interações. Mas a questão do layout do espaço como fator de influência da troca de conhecimentos entre colaboradores é uma dimensão pouco considerada os pesquisadores da gestão organizacional, ficando restrito a arquitetos e designers a preocupação com a elaboração e configuração de um layout físico favorável. Considerando este contexto, o presente trabalho propõe, como objetivo geral, desenvolver uma sistemática que permita analisar a disposição do ambiente de trabalho com base na análise de redes sociais (SNA) com o intuito de promover a interação social e a transferência de conhecimentos entre os membros de uma equipe. A proposta desta dissertação é baseada em uma abordagem combinada de métodos quantitativos e estudo de caso. Nesses termos, os dados desta pesquisa buscam analisar a interação do layout físico com a transferência do conhecimento no ambiente de uma equipe médica. Essa interação foi analisada através da teoria das redes sociais. Como principais resultados obtiveram-se: (i) a sistematização da literatura sobre o tema da transferência do conhecimento e análise de redes sociais; (ii) análise e aplicação da prática das análises das redes sociais e estudo do layout e (iii) proposta de uma versão inicial de um artefato para auxiliar profissionais da gestão organizacional que se interessem em analisar a rede social de um ambiente antes de alterar ou elaborar um novo layout para que os colaboradores possam ter mais interação e com isso melhorar a transferência do conhecimento e, consequentemente, a inovação organizacional. / The contexts in which organizations operate and act have changed dramatically in recent years. In this sense, the physical space and the organization are connected. The famous words said by Winson Churchill in 1943: “We shape our buildings and afterwards our building shape us”, indirectly already noted the importance of the physical space and interaction between individuals. The design of office spaces is often guided by general typologies (cellular, open and closed office) to describe and determine the quality of interactions in office structures. However, the layout of spaces, as an influence factor for knowledge sharing between people, is a dimension little considered by researchers from the organizational management field. Architects and designers are the only concerned about the design and configuration of a physical layout to strengthen such interaction. Based in this context, this work proposes, as main objective, to develop a systematic that allows analyzing the work environment disposition based on both a network analysis and on a knowledge transfer perspective. This proposal is based on a combined quantitative and a case study approach. In these terms, the collected data was used to analyze the interaction of a medical team when considered the physical layout of their work environment. The interaction was analyzed through the theory of social networks. As main results, we highlight the following: (i) the systematization of the literature on the subject of knowledge transfer and social network analysis; (ii) a practical application of social networks in the studies of office layouts; and, (iii) the proposal of an artifact to help management professionals to analyze the social network of an environment before changing or developing a new layout focused on the improvement of people interaction and, consequently, improving the organizational innovation.

A social network analysis of interschool collaboration : staff relationships in a shared education partnership

Robinson, Gareth January 2016 (has links)
This thesis reports on the social structures underpinning interschool collaboration in the context of Shared Education and the networks of staff relations that have been developed for the purpose of overcoming systemic separation. Drawing upon social network theory, it is argued that in order to further the model of Shared Education the corresponding research and academic enterprise must move beyond the analogous use of the term ‘network’ and consider the concept in a more analytical manner. In this sequential mixed methods case study, an exploratory network analysis of the staff members (n=97) from five collaborating primary schools in a Shared Education partnership was performed using a socio-metric instrument to examine four collaborative interactions—exchanging resources, seeking professional knowledge, discussing personal matters, and meeting socially. This was then followed by semi-structured interviews with the staff members (n=16) observed as most central within the partnership's network. The findings of this study suggest that Shared Education can facilitate network structures that overcome systemic separation; that partner preference is based upon desirable structural characteristics; that partnership sustainability may be an extension of social network adaptability; that Shared Education offered an alternative model for collegial engagement; that the model can facilitate learning relationships and knowledge creation; and that relational embeddedness is also observed to be a critical aspect of the partnership's leadership. Therefore, it is advocated that those researching Shared Education must develop a more nuanced approach to thinking about the structure of partnerships and the relationships that constitute them.

Epizoological tools for acute hepatopancreatic necrosis disease (AHPND) in Thai shrimp farming

Saleetid, Nattakan January 2017 (has links)
Acute hepatopancreatic necrosis disease (AHPND) is an emerging bacterial infection in shrimp that has been widespread across the major world shrimp producing countries since 2009. AHPND epizootics have resulted in a huge loss of global shrimp production, similar to that caused by white spot disease in the 1990’s. The epizootiological understanding of the spread of AHPND is still in its early stages, however, and most of the currently published research findings are based on experimental studies that may struggle to capture the potential for disease transmission at the country scale. The main aim of this research, therefore, is to develop epizootiological tools to study AHPND transmission between shrimp farming sites. Some tools used in this research have already been applied to shrimp epizoology, but others are used here for the first time to evaluate the spread of shrimp diseases. According to an epizootiological survey of AHPND in Thailand (Chapter 3), the first case of AHPND in the country was in eastern shrimp farms in January 2012. The disease was then transmitted to the south in December 2012. The results obtained from interviews, undertaken with 143 sample farms were stratified by three farm-scales (large, medium and small) and two locations (east and south). Both the southern location and large-scale farming were associated with a delay in AHPND onset compared with the eastern location and small- and medium-scale farming. The 24 risk factors (mostly related to farming management practices) for AHPND were investigated in a cross-sectional study (Chapter 3). This allowed the development of an AHPND decision tree for defining cases (diseased farms) and controls (non-diseased farms) because at the time of the study AHPND was a disease of unknown etiology. Results of univariate and unconditional logistic regression models indicated that two farming management practices related to the onset of AHPND. First, the absence of pond harrowing before shrimp stocking increased the risk of AHPND occurrence with an odds ratio () of 3.9 (95 % CI 1.3–12.6; P‑value = 0.01), whereas earthen ponds decreased the risk of AHPND with an of 0.25 (95 % CI 0.06–0.8; P‑value = 0.02). These findings imply that good farming management practices, such as pond-bottom harrowing, which are a common practice of shrimp farming in earthen ponds, may contribute to overcoming AHPND infection at farm level. For the purposes of disease surveillance and control, the structure of the live shrimp movement network within Thailand (LSMN) was modelled, which demonstrated the high potential for site-to-site disease spread (Chapter 4). Real network data was recorded over a 13-month period from March 2013 to March 2014 by the Thailand Department of Fisheries. After data validation, c. 74 400 repeated connections between 13 801 shrimp farming sites were retained. 77 % of the total connections were inter-province movements; the remaining connections were intra-province movements (23 %). The results demonstrated that the LSMN had properties that both aided and hindered disease spread (Chapter 4). For hindering transmission, the correlation between and degrees was weakly positive, i.e. it suggests that sites with a high risk of catching disease posed a low risk for transmitting the disease (assuming solely network spread), and the LSMN showed disassortative mixing, i.e. a low preference for connections joining sites with high degree linked to connections with high degree. However, there were low values for mean shortest path length and clustering. The latter characteristics tend to be associated with the potential for disease epidemics. Moreover, the LSMN displayed the power-law in both and degree distributions with the exponents 2.87 and 2.17, respectively. The presence of power-law distributions indicates that most sites in the LSMN have a small number of connections, while a few sites have large numbers of connections. These findings not only contribute to a better understanding of disease spread between sites, therefore, but also reveal the importance of targeted disease surveillance and control, due to the detection of scale-free properties in the LSMN. Chapter 5, therefore, examined the effectiveness of targeted disease surveillance and control in respect to reducing the potential size of epizootics in the LSMN. The study untilised network approaches to identify high-risk connections, whose removal from the network could reduce epizootics. Five disease-control algorithms were developed for the comparison: four of these algorithms were based on centrality measures to represent targeted approaches, with a non-targeted approach as a control. With the targeted approaches, technically admissible centrality measures were considered: the betweenness (the number of shortest paths that go through connections in a network), connection weight (the frequency of repeated connections between a site pair), eigenvector (considering the degree centralities of all neighbouring sites connected to a specified site), and subnet-crossing (prioritising connections that links two different subnetworks). The results showed that the estimated epizootic sizes were smaller when an optimal targeted approach was applied, compared with the random targeting of high-risk connections. This optimal targeted approach can be used to prioritise targets in the context of establishing disease surveillance and control programmes. With complex modes of disease transmission (i.e. long-distance transmission like via live shrimp movement, and local transmission), an compartmental, individual-based epizootic model was constructed for AHPND (Chapter 6). The modelling uncovered the seasonality of AHPND epizootics in Thailand, which were found likely to occur between April and August (during the hot and rainy seasons of Thailand). Based on two movement types, intra-province movements were a small proportion of connections, and they alone could cause a small AHPND epizootic. The main pathway for AHPND spread is therefore long-distance transmission and regulators need to increase the efficacy of testing for diseases in farmed shrimp before movements and improve the conduct of routine monitoring for diseases. The implementation of these biosecurity practices was modelled by changing the values of the long-distance transmission rate. The model demonstrated that high levels of biosecurity on live shrimp movements (1) led to a decrease in the potential size of epizootics in Thai shrimp farming. Moreover, the potential size of epizootics was also decreased when AHPND spread was modelled with a decreased value for the local transmission rate. Hence, not only did the model predict AHPND epizootic dynamics stochastically, but it also assessed biosecurity enhancement, allowing the design of effective prevention programmes. In brief, this thesis develops tools for the systematic epizootiological study of AHPND transmission in Thai shrimp farming and demonstrates that: (1) at farm level, current Thai shrimp farming should enhance biosecurity systems even in larger businesses, (2) at country level, targeted disease control strategies are required to establish disease surveillance and control measures. Although the epizootiological tools used here mainly evaluate the spread of AHPND in shrimp farming sites, they could be adapted to other infectious diseases or other farming sectors, such as the current spread of tilapia lake virus in Nile tilapia farms.

Understanding Social Media Users via Attributes and Links

January 2014 (has links)
abstract: With the rise of social media, hundreds of millions of people spend countless hours all over the globe on social media to connect, interact, share, and create user-generated data. This rich environment provides tremendous opportunities for many different players to easily and effectively reach out to people, interact with them, influence them, or get their opinions. There are two pieces of information that attract most attention on social media sites, including user preferences and interactions. Businesses and organizations use this information to better understand and therefore provide customized services to social media users. This data can be used for different purposes such as, targeted advertisement, product recommendation, or even opinion mining. Social media sites use this information to better serve their users. Despite the importance of personal information, in many cases people do not reveal this information to the public. Predicting the hidden or missing information is a common response to this challenge. In this thesis, we address the problem of predicting user attributes and future or missing links using an egocentric approach. The current research proposes novel concepts and approaches to better understand social media users in twofold including, a) their attributes, preferences, and interests, and b) their future or missing connections and interactions. More specifically, the contributions of this dissertation are (1) proposing a framework to study social media users through their attributes and link information, (2) proposing a scalable algorithm to predict user preferences; and (3) proposing a novel approach to predict attributes and links with limited information. The proposed algorithms use an egocentric approach to improve the state of the art algorithms in two directions. First by improving the prediction accuracy, and second, by increasing the scalability of the algorithms. / Dissertation/Thesis / Doctoral Dissertation Computer Science 2014

Motivational and Social Network Dynamics of Ensemble Music Making: A Longitudinal Investigation of a Collegiate Marching Band

January 2015 (has links)
abstract: People are motivated to participate in musical activities for many reasons. Whereas musicians may be driven by an intrinsic desire for musical growth, self-determination theory suggests that this drive must also be sustained and supported by the social environment. Social network analysis is an interdisciplinary theoretical framework and collection of analytical methods that allows us to describe the social context of a musical ensemble. These frameworks are utilized to investigate the relationship of participatory motivation and social networks in a large Division I collegiate marching band. This study concludes that marching band members are predominantly self-determined to participate in marching band and are particularly motivated for social reasons, regardless of their experience over the course of the band season. The members who are highly motived are also more integrated into the band's friendship and advice networks. These highly integrated members also tend to be motivated by the value and importance others display for the marching band activity suggesting these members have begun to internalized those values and seek out others with similar viewpoints. These findings highlight the central nature of the social experience of marching band and have possible implications for other musical leisure ensembles. After a brief review of social music making and the theoretical frameworks, I will provide illustrations of the relationship between motivation and social networks in a musical ensemble, consider the implications of these findings for promoting self-determined motivation and the wellbeing of musical ensembles, and identify directions for future research. / Dissertation/Thesis / Doctoral Dissertation Music 2015

Ethnicity, Family, and Social Networks: A Multiscalar Bioarchaeological Investigation of Tiwanaku Colonial Organization in the Moquegua Valley, Peru

January 2016 (has links)
abstract: Many models of colonial interaction are build from cases of European colonialism among Native American and African peoples, and, as a result, they are often ill-suited to account for state expansion and decline in non-Western contexts. This dissertation investigates social organization and intraregional interaction in a non-western colonial context to broaden understanding of colonial interaction in diverse sociocultural settings. Drawing on social identity theory, population genetics, and social network analysis, patterns of social organization at the margins of the expansive pre-Hispanic Tiwanaku state (ca. AD 500-1100) are examined. According to the dual diaspora model of Tiwanaku colonial organization in the Moquegua Valley of southern Peru, Chen Chen-style and Omo-style ethnic communities who colonized the valley maintained distinct ethnic identities in part through endogamous marriage practices. Biodistance analysis of cranial shape data is used to evaluate regional gene flow among Tiwanaku-affiliated communities in Moquegua. Overall, results of biodistance analysis are consistent with the dual diaspora model. Omo- and Chen Chen-style communities are distinct in mean cranial shape, and it appears that ethnic identity structured gene flow between ethnic groups. However, there are notable exceptions to the overall pattern, and it appears that marriage practices were structured by multiple factors, including ethnic affiliation, geographic proximity, and smaller scales of social organization, such as corporate kin groups. Social network analysis of cranial shape data is used to implement a multi- and mesoscalar approach to social organization to assess family-based organization at a regional level. Results indicate the study sample constituted a social network comprised of a dense main component and a number of isolated actors. Formal approaches for identifying potential family groups (i.e., subgroup analysis) proved more effective than informal approaches. While there is no clear partition of the network into distinct subgroups that could represent extended kin networks or biological lineages, there is a cluster of closely related individuals at the core of the network who integrate a web of less-closely related actors. Subgroup analysis yielded similar results as agglomerative hierarchical cluster analysis, which suggests there is potential for social network analysis to contribute to bioarchaeological studies of social organization and bioarchaeological research in general. / Dissertation/Thesis / Doctoral Dissertation Anthropology 2016

Re-Seeing Composition: Object Oriented Reflective Teaching Practice

January 2017 (has links)
abstract: This dissertation presents reflective teaching practices that draw from an object-oriented rhetorical framework. In it, practices are offered that prompt teachers and students to account for the interdependent relationships between objects and writers. These practices aid in re-envisioning writing as materially situated and leads to more thoughtful collaborations between writers and objects. Through these practices, students gain a more sophisticated understanding of their own writing processes, teachers gain a more nuanced understanding of the outcomes of their pedagogical choices, and administrators gain a clearer vision of how the classroom itself affects curriculum design and implementation. This argument is pursued in several chapters, each presenting a different method for inciting reflection through the consideration of human/object interaction. The first chapter reviews the literature of object oriented rhetorical theory and reflective teaching practice. The second chapter adapts a methodology from the field of Organizational Science called Narrative Network Analysis (NNA) and leads students through a process of identifying and describing human/object interaction within narratives and asks students to represent these relationships visually. As students undertake this task they can more objectively examine their own writing processes. In the third chapter, video ethnographic methodologies are used to observe object oriented rhetoric theory in practice through the interactions of humans and objects in the writing classroom. Through three video essays, clips of footage taken of a writing classroom and its writing objects are selected and juxtaposed to highlight the agency and influence of objects. In chapter four, a tool developed using freely available cloud-based web applications is presented which is termed the “Fitness Tracker for Teaching.” This tool is used to regularly collect, store, and analyze data that students self-report through a daily class survey about their work efforts, their work environment, and their feelings of confidence, productivity, and self-efficacy. The data gathered through this tool provides a more complete understanding of student effort and affect than could be provided by the teacher’s and students’ own memories or perceptions. Together these chapters provide a set of reflective practices that reinforce teaching writing as a process that is affective and embodied and acknowledges and accounts for the rhetorical agency of objects. / Dissertation/Thesis / Chapter 3 Video Presentation / Doctoral Dissertation English 2017
