Understanding the sense of community and continuance intention in virtual communities: The role of commitment and type of community

2019

Virtual communities (VCs) have become essential in current organizations and society, and so their sustainability is a topic of interest for researchers and practitioners. We focus on the sense of virtual community (SoVC) and commitment as relevant antecedents in achieving the success and maintenance of different types of VCs (communities of interest, virtual learning communities, and virtual communities of practice). Specifically, this study examines a moderated mediation model in which the type of virtual community moderates the indirect effect of a SoVC on the intention to continue through the perceived commitment of the users of the VC. The sample consists of 299 members of Virtual comm…

Identity and Online Groups

2017

Questions related to identity have been central to discussions on online communication since the dawn of the Internet. One of the positions advocated by early Internet pioneers and scholars on computer-mediated communication was that online communication would differ from face-to-face communication in the way traditional markers of identity (such as gender, age, etc.) would be visible for interlocutors. It was theorized that these differences would manifest both as reduced social cues as well as greater control in the way we present ourselves to others. This position was linked to ideas about fluid identities and identity play inherent to post-modern thinking. Lately, the technological and …

Learning 2.0 : the online community for apprenticeship

2012

International audience; Training courses are a strategic challenge for any organizations. E-learning solutions appears as a relevant alternative for the company training expense (fewer raised prices for the customer, fewer traveling for the learners and trainers, mentored learning, timetable flexible…). Recently, the emerging of Web 2.0 eras has shown that the online user behavior has changed. Now, the online users are likely to share their knowledge and gain acknowledgement How the construction of e-learning communities, in mobile or non-mobile using spaces, appears as efficient for distant apprenticeship? Our paper deal with a communicational approach of the e-learning for professional tr…

Global urban environmental change drives adaptation in white clover

2022

Made available in DSpace on 2022-04-28T19:52:06Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-03-18 Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations in 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense that also affects tolerance to abiotic stressors. Urban-rural gradients were associated with the evolution of clines in defense in 47% of cities throughout the world. Variation in the strength of clines was explained by environmental changes in drought stress and vegetation cover that varied am…

Creating ‘Communities of Practice’ to Enhance Ecosocial Work : A Comparison between Finland and Australia

2022

Abstract This article reports on findings from a small qualitative study in two industrialised countries—Finland and Australia, which aimed to engage social work practitioners in ‘communities of practice’ to collaboratively explore ecosocial work practice. Using a Participatory Action Research approach, a series of workshops were established to plan, implement and evaluate ecosocial work interventions. Data were gathered using qualitative pre- and post-surveys to examine changes to practice, including similarities and differences between Finnish and Australian practitioners. Overall, results indicated that practitioner engagement in the workshops increased their capacity to implement ecosoc…

Weed vegetation of cereal crops in Tajikistan (Pamir Alai Mts., Middle Asia)

2013

The paper presents results of investigations of weed vegetation conducted in crop fields, in Tajikistan (Middle Asia) - one of the world cradles of the weed flora. The study has been based on 299 phytosociological relevés obtained in various geobotanical regions of the country in 2009-2012. In the examined vegetation patches 469 vascular plant species were noted. Many of the recorded species are widespread weeds. However, there were also some rare and endemics taxa (e.g. Prangos pabularia, P. saraw-schanica and Thlaspidium thlaspi) observed in the sample plots. The collected material presents probably, the majority of the variability among the weed communities of crop cultivations in the Mi…

Un balance de la modernización autonómica y las relaciones intergubernamentales

2015

International audience; This article contains an overview of the modernization of the regional administrations since its inception until present. We distinguish roughly four modernizing cycles: the first is mainly identified with the search for legitimacy and survival of the regional administrations. The second is inspired by the New Public Management (NPM) and the emergence of a post-burocratic paradigm that enables the development of new methodologies. The third is characterized by the primacy of e-administration and quality policies applied to public services. Finally, the last cycle poses antagonistic tendencies, according to the outbreak of the current economic crisis.; En este artícul…

Contributions of mean and shape of blood pressure distribution to worldwide trends and variations in raised blood pressure: A pooled analysis of 1018…

2018

Background: Change in the prevalence of raised blood pressure could be due to both shifts in the entire distribution of blood pressure (representing the combined effects of public health interventions and secular trends) and changes in its high-blood-pressure tail (representing successful clinical interventions to control blood pressure in the hypertensive population). Our aim was to quantify the contributions of these two phenomena to the worldwide trends in the prevalence of raised blood pressure. Methods: We pooled 1018 population-based studies with blood pressure measurements on 88.6 million participants from 1985 to 2016. We first calculated mean systolic blood pressure (SBP), mean dia…
