ICT and environmental sustainability : a case study of a grassroots initiative
Increasingly, local communities develop projects and grassroots
initiatives that address climate change and other environmental sustainability
issues. These projects often commence informally and adopt web-based free
information and communication technologies (ICT) applications to support
their functioning. ICT applications are used to promote the goals of the project,
to recruit more supporters and to facilitate debate among citizens sympathetic to
the cause of environmental stewardship. However, as some of these projects
evolve they become more complex. Struggling with lack of funding, the
solution is to imaginatively combine free web-based ICT applications, to adapt
existing open source applications, and even to develop customized solutions to
address the projectâs needs. We present the results of an exploratory case study
of a grassroots initiative with environmental sustainability goals. The study
shows some evidence of innovative practices in the appropriation of ICTs and
in the communication campaign. Implications of this research for online
communities and society are also discussed.Fundação para a CiĂȘncia e a Tecnologia (FCT

Adding complexity to theories of paradox, tensions, and dualities of innovation and change: introduction to Organization Studies Special Issue on paradox, tensions, and dualities of innovation and change
Approaches to paradox have deep historical roots. Eastern philosophers such as Lao Tzu and Confucius described the world as a mystical interplay of interdependent contradictions (Chen, 2002; Li, 2014). The Tao te Ching, for example, opens with the puzzling and circular first line, âThe Tao that can be told is not the eternal Tao.â Western scholars such as Aristotle and Hegel depicted paradox as irrational and unsolvable puzzles or double binds. The classic example is the liarâs paradox, with the statement âI am lyingâ leading one in strange loops between honesty and falsehood. Both these traditions stress that our greatest insights derive from grappling with intricate, interwoven and often irrational contradiction
Branching patterns in phylogenies cannot distinguish diversity-dependent diversification from time-dependent diversification
One of the primary goals of macroevolutionary biology has been to explain general trends in longâterm diversity patterns, including whether such patterns correspond to an upscaling of processes occurring at lower scales. Reconstructed phylogenies often show decelerated lineage accumulation over time. This pattern has often been interpreted as the result of diversityâdependent (DD) diversification, where the accumulation of species causes diversification to decrease through niche filling. However, other processes can also produce such a slowdown, including time dependence without diversity dependence. To test whether phylogenetic branching patterns can be used to distinguish these two mechanisms, we formulated a timeâdependent, but diversityâindependent model that matches the expected diversity through time of a DD model. We simulated phylogenies under each model and studied how well likelihood methods could recover the true diversification mode. Standard model selection criteria always recovered diversity dependence, even when it was not present. We correct for this bias by using a bootstrap method and find that neither model is decisively supported. This implies that the branching pattern of reconstructed trees contains insufficient information to detect the presence or absence of diversity dependence. We advocate that tests encompassing additional data, for example, traits or range distributions, are needed to evaluate how diversity drives macroevolutionary trends
Scholarly Commentaries on Hirschheimâs âAgainst Theoryâ

Each commentary is written by a renowned IS researcher. Following the individual commentaries is Hirschheimâs response to the commentaries. Each commentary provides an insightful exegesis on theory in its own right and, collectively, the commentaries and response provide thought-provoking reflections for researchers in IS and beyond
Virtual Team Leader Communication:Employee Perception and Organizational Reality
Based on a study of leader communication effectiveness conducted in a large human resource outsourcing firm, this article reports how virtual team membersâ perceptions of their leadersâ effective use of communication tools and techniques affect team performance outcomes. The study also investigates the role that trust plays in moderating the relationship between virtual team membersâ perceptions of their leadersâ effective use of communication and team performance. Analysis of 458 responses from 68 teams found a positive relationship between virtual team membersâ perceptions of leadersâ effective use of communications and team membersâ perception of their teamâs performance. The study also found that trust strengthens the relationship between perceived leader communication effectiveness and team performance results. Last, the study also revealed serious organizational alignment issues between what team members perceived to be effective leader communication, their perception of team performance outcomes, and the organizations performance measured by a balanced scorecard
E-government adoption: A cultural comparison
This is the author's accepted manuscript. The final published article is available from the link below. Copyright @ Springer Science + Business Media, LLC 2008.E-government diffusion is an international phenomenon. This study compares e-government adoption in the U.K. to adoption in the U.S. In particular, this study seeks to determine if the same factors are salient in both countries. Several studies have explored citizen acceptance of e-government services in the U.S. However, few studies have explored this phenomenon in the U.K. To identify the similarities and differences between the U.K. and the U.S. a survey is conducted in the U.K. and the findings are compared to the literature that investigates diffusion in the U.S. This study proposes a model of e-government adoption in the U.K. based on salient factors in the U.S. A survey is administered to 260 citizens in London to assess the importance of relative advantage, trust and the digital divide on intention to use e-government. The results of binary logistic regression indicate that there are cultural differences in e-government adoption in the U.K. and the U.S. The results indicate that of the prevailing adoption constructs, relative advantage and trust are pertinent in both the U.S. and the U.K., while ICT adoption barriers such as access and skill may vary by culture. Implications for research and practice are discussed
The Hugging Team: The Role of Technology in Business Networking Practices
Abstract. Technological devices for social networking are produced in droves and networking through media seems to be the way of getting ahead in business. We examine what role technology plays in the creation, development and maintenance of business relationships among entrepreneurs in Copenhagen. We find that mediated communication is useful in all stages of relational maintenance but only in a supportive role in relational development where co-presence and shared personal experiences take center-stage, generating trust necessary for business relationships to work. These trust-developing experiences take effort and hard work and although they can be successfully supported and even facilitated through the use of communication technologies, they need not be replaced or made simpler. The difficulties of creating these experiences make working business relationships viable in the uncertain and risky world of entrepreneurship
Multidimensional Facets of Perceived Risk in Mobile Travel Booking
Despite the growing prevalence of smartphones in daily life and travel context, travellers still perceive an extent of risk associated with using their smartphone to book travel products. In order to alleviate or reduce perceived risk, it is important to better understand the dimensions of and the factors that contribute to perceived risk. This study analysed 411 responses from an online panel to examine perceived risk in mobile travel booking and identified the following facets: time risk, financial risk, performance risk, privacy/security risk, psychological risk, physical risk, and device risk. Several antecedents of perceived risk were identified. Perceived collection of personal information via smartphones contributes positively, while consumer innovativeness, trust, and visibility contribute negatively to perceived risk. Further, the predictive validity of perceived risk is confirmed as it significantly explains perceived usefulness, attitude, and behavioural intention in mobile travel booking. Implications to manage perceived risk and its antecedents are provided
