Knowledge Sharing Among Tourists via Social Media: A Comparison Between Facebook and TripAdvisor
2016
This paper examines tourists' knowledge sharing behavior in social media. Based on social capital theory, we aim to examine the effects of three dimensions of social capital—structural (social interaction ties), cognitive (shared vision) and relational (trust)—for two different types of social media: Facebook and TripAdvisor. We propose a structural model that connects an antecedent (homophily) and a consequence (knowledge sharing through posting) of these main dimensions of social capital. An online survey is conducted with 1200 Spanish consumers. Based on the full sample, our structural equation modeling supports most of the hypothesized paths, while trust does not affect either social in…
Quantification and classification in education: What is at stake?
2021
Histories of statistics and quantification have demonstrated that systems of statistical knowledge participate in the construction of the objects that are measured. However, the pace, purpose, and scope of quantification in state bureaucracy have expanded greatly over the past decades, fuelled by (neoliberal) societal trends that have given the social phenomenon of quantification a central place in political discussions and in the public sphere. This is particularly the case in the field of education. In this article, we ask what is at stake in state bureaucracy, professional practice, and individual pupils as quantification increasingly permeates the education field. We call for a theoret…
Online Personal Narratives
2021
The aim of this chapter is to explore personal narratives and conversational stories of self-declared victims of abuse in the comments section of a knowledge-sharing platform, such as YouTube. The aim is to analyze the resemblance between the interaction and exchange of narratives in comments sections, on the one hand, and narrative group psychotherapy and self-help support groups, on the other. While previous research on storytelling mostly addresses professionally guided or produced narratives, this approach extends the production of these narratives to online communicative contexts. Firstly, the chapter looks at the theoretical tenets of storytelling. Secondly, a sociolinguistic, narrato…
Validity and fairness of a new entry diagnostics test in higher education economics
2020
Abstract Research has been focusing increasingly on measuring students’ prior economic knowledge in higher education. However, in German-speaking countries, valid instruments are rare. A diagnostic study investigated the validity and fairness of an internationally established economic knowledge test (adapted German version of TUCE IV and TEL IV) with a representative sample of 7664 students from 46 universities across Germany. Previous findings with the dataset ( Zlatkin-Troitschanskaia et al., 2019a ) suggest that native language significantly predicts missing answers in the knowledge test. Similar effects can be found for gender. After coding missing answers as incorrect, students with a …
Reviving the lost spaces under urban highways and bridges: an empirical study
2019
Purpose The fast development of urban movement infrastructures has created neglected urban places in cities. This study aims to provide users’ preferences for designing lost spaces that are a by-product of elevated urban highways (UHs) and bridges to develop a conceptual model for better environmental design. Design/methodology/approach This research is conducted by a combination of both qualitative and quantitative methods. In the first phase, to explore the citizen’s environmental preferences based on the Q-sort technique and in-depth interviews, the ideas of 50 users were considered up to data saturation. The preferences of people for designs under urban bridges were extracted by conten…
Developing an Analytical Framework for Analyzing and Comparing National E-Government Strategies
2020
Part 1: E-Government Foundations; International audience; Across the world, e-government strategies are developed for the effective digitalization of the public sector. They offer governments a framework for dealing with challenges such as technical and legal interoperability and collaboration between public and private sector stakeholders, and for promoting a future vision for a digital public sector. Since e-government strategies are policy document and, thus, likely to convey biased perspectives, analyses of these strategies can yield insights into these biases and different perspectives on public sector digitalization. Until now, there has been no widely recognized framework for systema…
Mitigation and reinforcement in general knowledge expressions
2020
Abstract Speakers often mitigate by downgrading their own role in their utterances, depersonalizing the origin of their utterances and de-focalizing the deictic-personal point of reference (Briz, 1998; Caffi, 2007). Linguistically, this can be accomplished by means of impersonalization, generalization and referencing general knowledge. Interestingly, using expressions that suggest the objective, general or shared status of information can, in some cases, lead to argumentative reinforcement or boosting 1 (Cornillie, 2007a, b; Caffi, 1999; Briz, 2016). Our goal is to examine the relationship between the functions of mitigation and reinforcement in indirect evidential expressions of common kno…
Using discourse markers to negotiate epistemic stance: A view from situated language use
2021
Abstract In this paper, I analyse the usage of a discourse marker =mari, belonging to the epistemic paradigm attested in Upper Napo Kichwa (Quechuan, Ecuador). I show that the use of =mari indicates that the information is known well to the speaker, but also to some extent familiar to the addressee. In situated language use, the marker contributes to creating a knowing epistemic stance of the speaker. The analysis presented here is based on a 13-h documentary corpus of interactive Upper Napo Kichwa discourse, recorded on audio and video. For the purpose of the paper, the relevant utterances are analysed in their broad interactional context, including not only the surrounding text, but also …
Drawing conclusions about what co-participants know: Knowledge-probing question–answer sequences in new employee orientation lectures
2019
This study aims to uncover the processes of interaction through which knowledge acquisition in new employee orientation is monitored and controlled. Using video-recordings of orientation lectures as data, the study focuses on question–answer sequences in which the lecturer’s question probes into the state of the employees’ knowledge; in particular, it looks at the third turn of the sequence, in which the lecturer comes to a conclusion concerning the participants’ knowledge. This is shown to be an unavoidably practical accomplishment, which is contingent on both the often ambivalent responses of the participants and the design of the knowledge-probing question. Also, the lecturer orients to…
A Smart Contract Based Recommender System
2019
Nowadays information available on the World Wide Web has reached unprecedented growth and it makes difficult for users to find the most relevant for them. In order to alleviate such issue, Recommender Systems (RSs) have been proposed to collect opinions and preferences about a set of items, process such preferences and build a personalized information access. While the most part of current RSs exploit centralized architecture to provide the service, in this manuscript we propose an alternative approach for building a general purpose RSs that provides to users with more transparent and decentralized rating strategy. Indeed, the proposed framework is built on top of a Distributed Ledger techn…
