This thesis addresses the question of how business schoolsestablished as public privatepartnerships (PPPs) within a regional university in the English-speaking Caribbean survived for over twenty-one years and achieved legitimacy in their environment. The aim of the study was to examine how public and private sector actors contributed to the evolution of the PPPs. A social network perspective provided a broad relational focus from which to explore the phenomenon and engage disciplinary and middle-rangetheories to develop explanations. Legitimacy theory provided an appropriate performance dimension from which to assess PPP success. An embedded multiple-case research design, with three case sites analysed at three levels including the country and university environment, the PPP as a firm and the subgroup level constituted the methodological framing of the research process. The analysis techniques included four methods but relied primarily on discourse and social network analysis of interview data from 40 respondents across the three sites. A staged analysis of the evolution of the firm provided the ‘time and effects’ antecedents which formed the basis for sense-making to arrive at explanations of the public-private relationship-influenced change. A conceptual model guided the study and explanations from the cross-case analysis were used to refine the process model and develop a dynamic framework and set of theoretical propositions that would underpin explanations of PPP success and legitimacy in matched contexts through analytical generalisation. The study found that PPP success was based on different models of collaboration and partner resource contribution that arose from a confluence of variables including the development of shared purpose, private voluntary control in corporate governance mechanisms and boundary spanning leadership. The study contributes a contextual theory that explains how PPPs work and a research agenda of ‘corporate governance as inspiration’ from a sociological perspective of ‘liquid modernity’. Recommendations for policy and management practice were developed.

This research explored how a more student-directed learning design can support the creation of togetherness and belonging in a community of distance learners in formal higher education. Postgraduate students in a New Zealand School of Education experienced two different learning tasks as part of their online distance learning studies. The tasks centered around two online asynchronous discussions each for the same period of time and with the same group of students, but following two different learning design principles. All messages were analyzed using a twostep analysis process, content analysis and social network analysis. Although the findings showed a balance of power between the tutor and the students in the first high e-moderated activity, a better pattern of group interaction and community feeling was found in the low e-moderated activity. The paper will discuss the findings in terms of the implications for learning design and the role of the tutor.

This paper examines the extent to which both network structure and spatial factors impact on the organizational performance of universities as measured by the generation of industrial research income. Drawing on data concerning the interactions of universities in the UK with large research and development (R&D)-intensive firms, the paper employs both social network analysis and regression analysis. It is found that the structural position of a university within networks with large R&D-intensive firms is significantly associated with the level of research income gained from industry. Spatial factors, on the other hand, are not found to be clearly associated with performance, suggesting that universities operate on a level playing field across regional environments once other factors are controlled for.

Purpose: This paper aims to explore the role of internal and external knowledgebased linkages across the supply chain in achieving better operational performance. It investigates how knowledge is accumulated, shared, and applied to create organization-specific knowledge resources that increase and sustain the organization's competitive advantage. Design/methodology/approach: This paper uses a single case study with multiple, embedded units of analysis, and the social network analysis (SNA) to demonstrate the impact of internal and external knowledge-based linkages across multiple tiers in the supply chain on the organizational operational performance. The focal company of the case study is an Italian manufacturer supplying rubber components to European automotive enterprises. Findings: With the aid of the SNA, the internal knowledge-based linkages can be mapped and visualized. We found that the most central nodes having the most connections with other nodes in the linkages are the most crucial members in terms of knowledge exploration and exploitation within the organization. We also revealed that the effective management of external knowledge-based linkages, such as buyer company, competitors, university, suppliers, and subcontractors, can help improve the operational performance. Research limitations/implications: First, our hypothesis was tested on a single case. The analysis of multiple case studies using SNA would provide a deeper understanding of the relationship between the knowledge-based linkages at all levels of the supply chain and the integration of knowledge. Second, the static nature of knowledge flows was studied in this research. Future research could also consider ongoing monitoring of dynamic linkages and the dynamic characteristic of knowledge flows. Originality/value: To the best of our knowledge, the phrase 'knowledge-based linkages' has not been used in the literature and there is lack of investigation on the relationship between the management of internal and external knowledge-based linkages and the operational performance. To bridge the knowledge gap, this paper will show the importance of understanding the composition and characteristics of knowledge-based linkages and their knowledge nodes. In addition, this paper will show that effective management of knowledge-based linkages leads to the creation of new knowledge and improves organizations' operational performance.

This thesis reports on an exploratory study of the relationship between the Internet and women’s empowerment in China. The theoretical framework of the study combines feminist theorisations of power – the core concept of empowerment – with insights from sociological perspectives on power and gender, as well as collective action theory. This allows for the conceptualisation of women’s empowerment as a dynamic process that is shaped by a set of communicative practices. Focusing on female Chinese bloggers and women’s groups of different organisational types, this study aims to explore the respective ways in which these two types of women actors use the Internet with a view to examining whether, and the extent to which it enables them to generate a sense of empowerment. The empirical data mainly derives from interviews with female bloggers and with staff members from different women’s groups, as well as from a features analysis and social network analysis of the sampled blogs and official websites of studied groups. Overall, the findings suggest that the opportunities offered by the Internet for women’s empowerment through awareness-raising, social interactions, and the organising of collective action, are limited. For female bloggers, their activities do not translate the new communicative practices afforded by the Internet into concrete action to bring about changes in their everyday life. On the contrary, blogs become an alternative platform to discipline their behaviours and to reinforce patriarchal gendered norms. Moreover, the research finds that the promise of empowerment is further undermined by the pervasive commercialisation of the Internet and state control. For women’s groups, contextual factors prevent them from fully realising the potential of the Internet for increasing their organisational visibility, promoting public awareness about gender issues, building a sense of the collective, campaigning, or networking. The major barriers in these processes are state control, a lack of resources, online censorship, and at times, competition from commercial sites. In this respect, the Internet does not play a significant role in forming a collective to challenge existing unjust power relations.

This article presents a methodological proposition to map the diversity of the audiovisual industry in the digital scenario by portraying the most important interactions between those who create, produce, distribute and disseminate audiovisual productions on line, paying special attention to powerful intermediaries and to small and medium independent agents. Taking as a point of departure a flexible understanding of social network analysis, the aim is to understand the structure of the audiovisual industry on the internet so that, taking into consideration a given sector, agents, their relations and the networks they give place to – as well as the structural conditions under which they operate – are studied. The aim is to answer questions such as: what is mapping, what is of interesting to map, how can it be done and what advantages and disadvantages the results will present.

Las relaciones públicas se configuran como una actividad esencial en la gestión de la comunicación con los públicos de los clubes de fútbol ya que son muy activos y su grado de reactividad es alto. Con este texto se analiza el papel que desempeñan las redes sociales en los clubes de fútbol que poseen mayor número de ingresos. Para ello, se desarrolla una metodología que estudia qué presencia tienen en las redes sociales, el número de seguidores, qué grado de interacción se produce entre clubes y públicos y los contenidos y las temáticas de los textos de las redes sociales. Los resultados muestran un público activo pero con intervenciones relacionadas con los resultados futbolísticos y una gestión comunicativa unidireccional por parte de los clubes.

Este artículo presenta una investigación en la que se analizan las dificultades del profesorado para planificar, coordinar y evaluar competencias claves en una muestra de 23 centros educativos. El tema tiene hondas repercusiones ya que una mala praxis educativa de las competencias claves puede conculcar uno de los derechos fundamentales del alumnado a ser evaluado de forma objetiva (LODE: Art.6b y RD 732/1995: Art. 13.1) y poder superar las pruebas de evaluación consideradas necesarias para la obtención del título académico mínimo que otorga el estado español. La investigación se ha desarrollado desde una doble perspectiva metodológica; en primer lugar, es una investigación descriptiva en la que presentamos las características fundamentales de las competencias claves y la normativa básica para su desarrollo y evaluación. En segundo lugar,  aplicamos un procedimiento de análisis con una doble vertiente cualitativa mediante el empleo del programa Atlas-Ti y del enfoque reticular-categorial del análisis de redes sociales con la aplicación de UCINET y el visor yED Graph Editor para abordar el análisis de las principales dificultades y obstáculos detectados. Los resultados muestran que existen serias dificultades en las tres dimensiones analizadas: "planificación", "coordinación" y "evaluación" de competencias clave; especialmente en la necesidad de formación del profesorado, en la evaluación de las competencias, en la metodología para su desarrollo y en los procesos de coordinación interna para su consecución en los centros educativos.

Text cohesion is an important element of discourse processing. This paper presents a new approach to modeling, quantifying, and visualizing text cohesion using automated cohesion flow indices that capture semantic links among paragraphs. Cohesion flow is calculated by applying Cohesion Network Analysis, a combination of semantic distances, Latent Semantic Analysis, and Latent Dirichlet Allocation, as well as Social Network Analysis. Experiments performed on 315 timed essays indicated that cohesion flow indices are significantly correlated with human ratings of text coherence and essay quality. Visualizations of the global cohesion indices are also included to support a more facile understanding of how cohesion flow impacts coherence in terms of semantic dependencies between paragraphs.

O objetivo central desta pesquisa foi identificar se os indivíduos que recebem maior indicação de afinidade pelos membros da rede social em que estão inseridos na empresa são aqueles considerados possuidores de maior participação colaborativa pelos gestores. O estudo foi realizado com 17 funcionários do setor produtivo de uma pequena empresa metalúrgica localizada em São Caetano do Sul - SP. Inicialmente, utilizou-se a técnica de Análise de Redes Sociais (SNA-Social Network Analysis) através do software UCINET 6.0, considerando-se o critério de afinidade. Cada funcionário indicou um nível de afinidade que possui com cada um dos demais participantes da rede. A SNA permite diversas análises das relações entre os componentes da rede úteis para os gestores, e algumas delas são mostradas neste artigo. Porém, o foco principal do trabalho foi primeiramente identificar quais indivíduos (nós da rede) recebem maior número de manifestações de afinidade (variável afinidade). Numa segunda etapa, coletou-se a percepção dos gestores do setor com relação à disposição em colaborar de cada funcionário (variável disposição em colaborar). Finalmente, utilizando o software SPSS 15, realizou-se teste estatístico onde foi verificada a existência de forte correlação entre as duas varáveis. Assim, o estudo indicou que os funcionários que recebem maior número de manifestações de afinidade dos colegas são os que têm maior disposição em colaborar, segundo os gestores da empresa. Esta constatação indica que, se os gestores buscarem formas de estimular a inserção social dos funcionários, provavelmente haverá aumento nos níveis de participação colaborativa.

Objetivos: O presente estudo tem como objetivo analisar as redes sociais pessoais de idosos portugueses com filhos segundo o sexo da descendência e o sexo do/a idoso/a, relativamente às características estruturais, funcionais e relacionais-contextuais. Metodologia: Para a avaliação das variáveis em estudo foram utilizados o Instrumento de Análise da Rede Social Pessoal, versão para idosos (IARSP – Idosos) (Guadalupe, 2010; Guadalupe & Vicente, 2012) para avaliar as dimensões da rede social pessoal e um inquérito por questionário para caracterização da amostra a nível sociodemográfico e sociofamiliar. Participantes: A amostra é constituída por 498 idosos com filhos, com uma média de idades de 75 anos (DP=7,487), entre os 65 anos e os 98 anos, maioritariamente do sexo feminino (60,8%), casados ou em união facto (58,4%) e com escolaridade (70,7%). A maioria dos idosos inquiridos reside em aglomerado populacional (90,8%) e não usufrui de apoio de respostas sociais (78,1%). Resultados: Na análise separámos 3 subamostras: idosos com filhos de ambos os sexos (n=218; 43,7%), idosos com filhos do sexo masculino (n=125; 25,2%) e idosos com filhos do sexo feminino (n=155; 31,2%). Os idosos com filhas apresentam valores mais elevados no apoio material e instrumental (p = 0,046), apoio informativo (p = 0,018), companhia social (p = 0,018) e reciprocidade de apoio (p < 0,001). O tamanho da rede é menor no caso dos idosos com filhas comparativamente aos que têm filhos de ambos os sexos (p = 0,012). Analisando separadamente as redes das idosas e dos idosos da amostra, assinalamos que nas redes de idosos do sexo masculino apenas houve diferença na reciprocidade (p = 0,016), sendo menos recíprocas as redes da subamostra com filhos apenas do sexo masculino; por sua vez, nas redes das idosas houve diferenças no tamanho da rede (p = 0,015) e na frequência de contactos (p = 0,019) sendo maior nas idosas com filhos de ambos sexos; na proporção de relações de vizinhança na rede (p = 0,005), sendo menor nas idosas que têm filhos de ambos os sexos; no apoio informativo (p = 0,022) e na reciprocidade (p = 0,005) sendo menores nas idosas com filhos do sexo masculino. Conclusões: O nosso estudo revela que o sexo dos filhos influencia as redes sociais pessoais dos pais e mães idosos/as a nível funcional, estrutural e relacional-contextual, sobretudo no caso das mulheres idosas, uma vez que as redes das idosas apresentam diferenças nas três dimensões, o que não se verifica nos pais idosos, verificando-se também que os idosos com filhas do sexo feminino têm redes mais centradas nas relações familiares. / Goals: This study aims to analyze the personal social networks structural, functional and relational-contextual characteristics of Portuguese seniors with offspring, according to their sex. Methodology: To the variables evaluation, we have used the Personal Social Network Analysis Instrument, Elderly Version (IARSP – Elderly) (Guadalupe, 2010; Guadalupe & Vicente, 2012) in order to evaluate the dimensions of the personal social network, and a questionnaire for demographic description. Participants: Our sample has 498 seniors with offspring, with an average of 75 years of age (DP = 7,487), between 65 and 98 years old, mostly females (60,8%), married (58,4%) with education (70,7%).The majority live on agglomeration (90,8%) and does not have the support of social services (78,1%). Results: In this analysis we've 3 groups: seniors with sons and daughters (n = 218; 43,7%), seniors with male offspring (n = 125; 25,2%) and seniors with female offspring ( n = 155; 31,2%). Seniors with daughters only shows higher values on material and instrumental support (p = 0,046), informative support (p = 0,018), social company (p = 0,018) and reciprocity support (p < 0,001). The network size is smaller on senior's with offspring, comparing the ones with sons and daughters (p = 0,012). On a separate analysis of the male and female seniors sample, it should be noticed that on the male seniors network there's been a difference on reciprocity only (p = 0,016) being less reciprocal the networks from the group exclusively with male sons; on the other end, on the female seniors network with sons and daughters there's been a difference on the network size (p = 0,015) and on the contact frequency (p = 0,019) being smaller on the seniors with offspring from both sex; on the proportion relation of network neighborhood (p = 0,005), smaller on the female seniors with sons and daughters; on informative support (p = 0,022) and on the reciprocity (p = 0,005), being smaller on the female seniors with male offspring. Conclusions: Our study reveals that the male and female offspring influences the personal social networks of senior mothers and fathers on a functional, structural and context-relational level, mostly on women, once that their network presents differences in the three dimension, something that does not happen with senior fathers, with the verification that the seniors with daughters do have social networks that are more centered in family relations.

Objetivos: A investigação tem como objetivo geral analisar a associação entre a satisfação com a vida nos idosos e as características estruturais, funcionais e relacionais-contextuais das suas redes sociais pessoais. Metodologia: A recolha dos dados foi feita através de um questionário sociodemográfico, da Satisfaction With Life Scale – SWLS (Diener, 1985) que permite avaliar o grau de satisfação com a vida e também do Instrumento de Avaliação da Rede Social Pessoal – IARSP – Idosos (Guadalupe, 2009; Guadalupe & Vicente, 2012) que possibilita a análise das características das redes sociais pessoais dos idosos. Participantes: A amostra é constituída por 416 idosos com idades compreendidas entre os 65 anos e os 98 anos (M = 76,15; DP = 7,584). Os participantes são de ambos os sexos, mas na sua maioria do sexo feminino (63,7%; n = 265). A maioria dos sujeitos da amostra é casada (51,2%; n = 213) e tem escolaridade (64,2%; n = 267). Resultados: Verifica-se que são as mulheres idosas, os casados e com escolaridade que percebem uma maior satisfação com a vida. Constata-se que existe uma maior proporção de idosos satisfeitos com a vida (53,8%; n = 83) em comparação com os medianamente satisfeitos (26,2%; n = 109) e com os insatisfeitos (20%; n = 83). Os idosos que apresentam uma maior satisfação percebida têm uma média mais elevada na proporção das relações familiares nas redes (M = 80,67), no apoio emocional, material e instrumental, informativo, companhia social, e no acesso a novos vínculos, e consideram estar muito satisfeitos tanto com a rede (M = 2,92) como com o apoio que esta disponibiliza (M = 2,77). Conclusão: Verificaram-se associações estatisticamente significativas nas características estruturais da rede, no entanto são as características funcionais que atestam os principais resultados que nos permitem afirmar uma associação entre satisfação com a vida nos idosos e as relações interpessoais, pelo conteúdo das relações e pelo apoio que percecionam. Concluímos que os idosos que se consideram satisfeitos com a vida apresentavam, na generalidade, características de rede social mais positivas quando comparados com os que percebiam menor satisfação com a vida. / Objectives: The research has as main objective to analyze the association between life satisfaction in the elderly and the structural, functional and relational-contextual characteristics of their personal social networks. Methodology: The data collection was done through a sociodemographic questionnaire, the Satisfaction With Life Scale – SWLS (Diener, 1985) that evaluates the degree of satisfaction with life and also the Personal Social Network Analysis Tool – IARSP – Elderly (Guadalupe, 2009; Guadalupe & Vicente, 2012) for the analysis of personal social networks’ characteristics. Participants: The sample consisted of 416 elderly aged between 65 and 98 years (M = 76,15; SD = 7,584). Participants are both genders, but mostly female (63,7%; n =265). Most of the participants are married (51,2%; n = 213) and have education (64,2%; n = 267). Results: It is found that are the older women, married and with education that perceive a greater satisfaction with life. There is a greater proportion of elderly satisfied with the lives (53,8%; n = 83) compared to the moderately satisfied (26,2%; n = 109) and the unsatisfied (20%; n = 83). Seniors who have a higher satisfaction have a higher average in the proportion of family relationships in their networks (M = 80,67), emotional support, material and instrumental, informational, social companionship, and access to new bonds, and consider to be very satisfied with their social network (M = 2,92) and with the social support that it provides (M = 2,77). Conclusion: There were statistically significant associations in the structural characteristics of the network, however are the functional characteristics that allow us to state an association between life satisfaction in the elderly through interpersonal relationships, the content of relations and the support they perceive. We conclude that elderly people who consider themselves satisfied with life showed, in general, have more positive characteristics of social personal network when compared to those who perceive less satisfaction with life.
