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…
Cross-Cultural Validity of the Emotion Matching Task
2019
Objectives We aimed to provide evidence of the cross-cultural validity of the Emotion Matching Task (EMT), as a measure of emotion knowledge in preschool children in different cultures, namely, the United States, Italy, and Spain. In particular, we analyzed: (1) the psychometric properties of the scale in each of the three subsamples; (2) the relations between sex, age, verbal ability, and EK, in the overall sample and in the three different cultures; (3) the pattern of acquisition of the various dimensions of emotion knowledge in the overall sample and in the three different countries. Methods Participants were 500 children from Spain (N = 180), the United States (N = 158), and Italy (N = …
An analysis of recent research on venture capital networks
2019
Purpose – this paper examines recent trends in venture capital network research. Network analysis is a useful approach for analyzing inter-organizational networks, especially for venture capitalists, which are characterized by plenty of connections. Although important steps ahead have been made, several research questions are still unanswered. Research methodology – this brief review analyses deeply three papers which are representative of the novel scientific literature in this field. Scrutinizing these works, I identify their points of strength and weaknesses, in order to understand how to pave the way for further research. Findings – this paper shows that the study of network weak ties a…
Governing Complex Strategic Networks: Emergence Versus Enabling Effects
2017
In today’s knowledge-based economy, the sources of competitive advantage increasingly lie in webs of relationships between a variety of firms and organizations that, over time, lead to the emergence of strategic networks. As the performances of both the network actors and the whole network are strictly linked with the coordination and governance of network actors and their activities, this study aims to shed light on the ways in which the processes of network coordination and governance take place. Strategic networks are here viewed as complex adaptive systems, and the twin nature of the processes of strategic network coordination and governance is examined. On one hand, I underscore the em…
Corporate Governance Theories: From Micro Theories to National Systems Theories
2004
The objective of this article is to conduct a survey of the different corporate governance theories. In the first part, we present the micro theories by opposing the disciplinary view to the knowledge-based view. The second part deals with the macro or national systems theories. We separate the theories based on appropriation of the organizational rent from those attributing a dominant role to production. This survey highlights that the financial view of corporate governance is a very particular case and presents many limits.
‘Drawing’ conclusions : Irish primary school children’s understanding of physical education and physical activity opportunities outside of school
2017
This study explores the relationship between primary school physical education and physical activity as sites for the practice of physical activity of Irish primary school children. Understanding how children make connections between physical activity sites is important in shaping physical education experiences that promote lifelong participation. Children’s (aged 8–11) awareness, knowledge, and understanding of physical activity and physical education were examined using participatory methods of ‘draw and write’ ( n = 135) and focus group interviews ( n = 34). In Phase 1, data collection focused on physical activity, while Phase 2 focused on physical education and connections between phys…
Environmental problems and Geographic education. A case study: Learning about the climate and landscape in Ontinyent (Spain)
2021
AbstractCultural perceptions of the environment bring us back to elements and factors guided by “natural” cause-effect principles. It seems that academic education has had little effect on the manner and results of learning about changes in the local landscape, especially as regards rational explanations. There is considerable difficulty relating academic concepts about the climate to transformations in the environmental landscape. Teaching tasks are mediatized due to the use of rigorous and precise concepts which facilitate functional and satisfactory learning. This is the objective of the research this article aims to undertake, for which we have chosen the case of Ontinyent (Spain). This…
Quine’s Fluted Fragment is Non-elementary
2016
We study the fluted fragment, a decidable fragment of first-order logic with an unbounded number of variables, originally identified by W.V. Quine. We show that the satisfiability problem for this fragment has non-elementary complexity, thus refuting an earlier published claim by W.C. Purdy that it is in NExpTime. More precisely, we consider, for all m greater than 1, the intersectionof the fluted fragment and the m-variable fragment of first-order logic. We show that this subfragment forces (m/2)-tuply exponentially large models, and that its satisfiability problem is (m/2)-NExpTime-hard. We round off by using a corrected version of Purdy’s construction to show that the m-variable fluted f…
Sharing cultural knowledge at work: a study of chat interactions of an internationally dispersed team
2015
Tässä artikkelissa tarkastellaan etnometodologisen jäsenkategorisoinnin analyysin avulla, kuinka kansainvälisesti hajautetun tiimin jäsenet jakavat kulttuurista tietoa Skype™ -keskusteluissaan. Tarkemmin katsotaan sitä, miten osallistujat luokittelevat itsensä ja muut tiimin jäsenet ’kulttuurisiksi tietäjiksi’ ja ’ei tietäjiksi’. Analyysissa havaittiin neljä tapaa, joilla tiimin jäsenet jakoivat tietoa samalla kun he hallinnoivat tehtävien jakelua ja suorittamista sekä rakensivat yhteisymmärrystä vuorovaikutuksessa. Tutkimuksen tulokset osoittavat, että kulttuurinen tieto on dynaamisesti muuttuvaa, kontekstisidonnaista ja vuorovaikutuksessa rakentuvaa. Sen sijaan että kulttuurisuus haittais…
