How Leader Role Identity Influences the Process of Leader Emergence: A Social Network Analysis

Contemporary literature on leadership emphasizes the importance of having a leader identity in building leadership skills and functioning effectively as leaders. We build on this approach by examining and unpacking the role of leader identity in leadership emergence. Taking the perspective that leadership is a dynamic social process between group members, we propose a social network-based process model whereby leader role identity predicts network centrality, which leads to leader emergence. We test our model using a sample of 88 cadets participating in a training course on leadership development. In support of our model, cadets who possess a stronger leader identity were more likely to emerge as leaders, as rated by peers and course trainers, and these relationships were mediated by two indicators of network centrality reflecting one’s ability to broker information (i.e., betweenness centrality) and one’s popularity (i.e., indegree centrality) within one’s group. Implications for research and practice are discussed

Study of the electronic structure of electron accepting cyano-films: TCNQ: Versus TCNE

In this article, we perform systematic research on the electronic structure of two closely related organic electron acceptor molecules (TCNQ and TCNE), which are of technological interest due to their outstanding electronic properties. These studies have been performed from the experimental point of view by the use electron spectroscopies (XPS and UPS) and supported theoretically by the use of ab-initio DFT calculations. The cross-check between both molecules allows us to identify the characteristic electronic features of each part of the molecules and their contribution to the final electronic structure. We can describe the nature of the band gap of these materials, and we relate this with the appearance of the shake-up features in the core level spectra. A band bending and energy gap reduction of the aforementioned electronic structure in contact with a metal surface are seen in the experimental results as well in the theoretical calculations. This behavior implies that the TCNQ thin film accepts electrons from the metal substrate becoming a Schottky n-junctionThis work was supported by the Spanish MICyT under grants No. FIS2016-74893-P and MAT2013-47869-C4-3-

A Longitudinal Investigation of Leader Development and Leadership Emergence

Although it requires time to develop and emerge as leaders, there is a shortage of longitudinal research on these topics. Across two essays, this dissertation aims to address this gap in the literature. Essay 1 examines the nature and degree of leader self-view development during formal leadership training. Drawing upon theories of leader development, it is suggested that as individuals acquire new leadership skills and knowledge, their leader efficacy and identity will develop. Testing competing predictions between developmental readiness (i.e., openness to change) and developmental necessity (i.e., room to change) perspectives, Essay 1 further examines whether learning goal orientation and motivation to lead predict how much and in what ways trainees developed in their leader self-views. Cadets (N = 240) participating in a leadership development course self-reported their leader self-views throughout the program. Using latent growth models, results provide evidence that individuals’ leader efficacy and identity developed–although differently–during leadership training. Moreover, results highlight the need to consider the developmental necessity perspective when allocating leadership development opportunities. Essay 2 examines the dynamic co-occurrence of leadership and trust over time. Drawing upon social exchange theory and models of social entrainment, it is suggested that trust can facilitate the emergence of informal leadership and informal leadership can facilitate the development of trust over time. Cadets (N = 123) participating in a leadership development course provided peer ratings of trust and leadership over time. Using stochastic actor-oriented models, results provide support that, over time, individuals initially perceived as trustworthy emerge as leaders and individuals initially perceived as leaders are trusted. Moreover, being trusting of others can facilitate one’s own leadership emergence over time. Overall, results across these two essays shed light on the longitudinal processes that affect how leaders develop and emerge

Language As Key Factor Of Long-Term Value Creation In Mergers And Acquisitions In The Telecommunications Sector

This article analyzes long-term value creation or destruction in mergers and acquisitions in the telecommunications sector. After characterizing the market targeted by the analysis (telecommunications) and discussing and selecting the most suitable long-term methodology, we will make an econometric analysis of telecommunications M&A in the period from 1995 to 2010. The research will focus on telephone companies or operators as leading players in the sector. Based on this econometric analysis, we clearly found evidence of value destruction (2000-2010) using different methodologies, and value creation in the M&A using same language in the involved companies. According with the type of operations, some political recommendations can be established. This is the first econometric study devoted to long-term value creation in telecommunications after the liberalization of the telecom market

Governance and economics of smart cities: opportunities and challenges

YesThis editorial introduction to this special issue provides an overview and a conceptual framework of governance and economics of smart cities. We begin with a discussion of the background to smart cities and then it focuses on the key challenges for consideration in smart city economics. Here it is argued that there are four dimensions to smart city economics: the first is regarding the scale of global market for smart cities; the second issue concerns data to be used for smart city projects; the third concerns market competition and structure and the fourth concerns the impact on local economy. Likewise, smart city governance framework has to be considered a layered and multi-level concept focusing on issues of transparency and accountability to the citizens

A Investigação Sobre o Discurso de Ódio no Campo da Comunicação: Uma Revisão Sistemática da Literatura

As revisões sistemáticas de literatura, embora tenham surgido no campo da saúde, constituem um grande apoio a investigadores de outras áreas, uma vez que o seu grande objetivo passa por entender o trabalho feito em torno de um determinado tema e conhecer os principais autores e as diferentes perspetivas adotadas. Para este trabalho, a técnica foi aplicada à base de dados Communication Abstracts, de forma a mapear a investigação relativa ao discurso de ódio: qual o foco dos trabalhos, quais os grupos mais estudados e quais as perspetivas e metodologias mais recorrentes. Após a análise a um universo de 85 artigos, foi possível concluir que, desde os anos 90, existe um grande interesse pela vertente legislativa e de regulação, que tem sido complementado, nos últimos anos, com um alargar ao campo do tipo de conteúdo presente no discurso de ódio

Educação e formação de adultos : um estudo quantitativo sobre destrezas tecnológicas

Nesta comunicação apresentamos os resultados de um estudo, sobre a utilização/construção de e-portefólios no contexto dos Cursos de Educação e Formação de Adultos – Nível Secundário (CEFA-NS). Para a elaboração de conteúdos com vista ao desenvolvimento de uma acção de formação contínua sobre a temática, avaliámos as destrezas tecnológicas de um grupo de formandos (n=170) e formadores (n=12) dos CEFA-NS que participaram na divulgação de uma plataforma de e-portefólios (Elgg) na Escola Secundária Padre Benjamim Salgado (ESPBS). Para a recolha de dados utilizou-se o inquérito por questionário e os dados foram tratados com recurso ao PASW (Predictive Analytics Software). Os resultados demonstram que as elevadas percentagens de utilização do computador, da Internet e do email permitem perceber que, os inquiridos, ao manterem um contacto constante com estas tecnologias, estão a interiorizar competências fundamentais no âmbito das Tecnologias de Informação e Comunicação. Contudo, a sua utilização varia em função da idade.The paper presents the results of a research concerning the use / construction of eportfolios in the context of Adult Education and Training - Secondary Level (CEFA-NS). In order to design the syllabus to develop a continuous session training, we analyze the technological skills from a group of trainees (n=170) and trainers (n=12) of CEFA-NS that participated in the dissemination of an e-portfolios platform (Elgg) on the Secondary School Padre Benjamim Salgado (ESPBS). Data were collected by a questionnaire and analyzed using the PASW (Predictive Analytics Software). The results show that the high percentages using computers, Internet and email evidence that the participants when they keep contact with these technologies, they are getting essential skills concerning the Technologies of Information and Communication. However, their use depends on how old each one is

Reconhecimento, validação e certificação de competências (RVCC): experiências de construção de portefólios reflexivos

Na sequência de um trabalho de investigação (Dias, 2007), procedemos à instalação e disponibilização da plataforma de eportefólio Elgg (open source) e a sessões para sua divulgação, na Escola Secundária Padre Benjamim Salgado (ESPBS). Neste momento, integrado num projecto de doutoramento, desenhámos um estudo para a dinamização da plataforma, em contexto de Educação e Formação de Adultos, cujos objectivos são: compreender e descrever de que modo a utilização do eportefólio pode contribuir, enquanto tecnologia e estratégia de ensino-aprendizagem e de avaliação para a construção dos portefólios reflexivos usados para a avaliação de competências, nos Cursos de Educação e Formação de Adultos e desenvolver o nível de literacia informática, quer dos formadores, quer dos formandos, promovendo uma cultura tecnológica crítica. Utilizando uma metodologia qualitativa, realizámos, nesta 1ª fase do trabalho, entrevistas semiestruturadas para um levantamento prévio das experiências desenvolvidas pelos formadores e Profissionais de RVC com os formandos, na construção do portefólio reflexivo de aprendizagens (PRA). A amostra é constituída por 6 formadores e 12 formandos e os dados foram analisados por recurso à análise de conteúdo (Bardin, 1994). Nesta comunicação, analisamos o significado do PRA para os entrevistados, assim como o processo de negociação estabelecido entre formador e formando na sua organização.CIE
