Ethnography goes online: towards a user-centred methodology to research interpersonal communication on the internet:

Abstract: Ethnographic research is increasingly concerned with how the internet operates within our everyday life. This article attempts to offer a methodological contribution of online communication and an exploration of initial empirical data generated with this methodology. The article calls for a specification of how ethnography can be applied appropriately to the study of relationships online. It departs from the real versus virtual dichotomy, offering a user-centred methodology to study interpersonal communications on the internet. It suggests the use of three main strategies to pay tribute to the characteristics of uses online: multi-situated, online and offline, and flexible and multimedia data collection methods. This approach facilitates a holistic analysis of the way in which social information and communication technologies operate within society in everyday life. It deals with the problem of defining the setting of research online and proposes an expanded ethnography. The article specifies details of this methodology for research into interpersonal communications and emotions online. It does so by drawing on empirical data generated in a study on everyday life and emotions on the internet. Epistemic questions related to this methodological approach will also be discussed. Overall, the exemplification suggests that the methodological approach proposed here is able to capture the uses and understandings of the internet.

ChaLearn Looking at People 2015: Apparent Age and Cultural Event Recognition Datasets and Results

Abstract: Following previous series on Looking at People (LAP) competitions [14] [13] [11] [12] [2], in 2015 ChaLearn ran two new competitions within the field of Looking at People: age and cultural event recognition in still images. We proposed a crowd-sourcing application to collect and label data about the age people looks like instead of the real age. In terms of cultural event recognition, one hundred categories had to be recognized. This involved scene understanding and human body analysis. This paper summarizes both challenges and data, as well as the results achieved by the participants of the competition. Details of the ChaLearn LAP competitions can be found at http://gesture.chalearn.org/.

Frontal eye field, where art thou? Anatomy, function, and non-invasive manipulation of frontal regions involved in eye movements and associated cognitive operations.

Abstract: The planning, control and execution of eye movements in 3D space relies on a distributed system of cortical and subcortical brain regions. Within this network, the Eye Fields have been described in animals as cortical regions in which electrical stimulation is able to trigger eye movements and influence their latency or accuracy. This review will focus on the Frontal Eye Field (FEF) a “hub” region located in Humans in the vicinity of the pre-central sulcus and the dorsal-most portion of the superior frontal sulcus. The straightforward localization of the FEF through electrical stimulation in animals is difficult to translate to the healthy human brain, particularly with non-invasive neuroimaging techniques. Hence, in the first part of this review, we will describe attempts made to characterize the anatomical localization of this area in the human brain. The outcome of functional Magnetic Resonance Imaging (fMRI), Magneto-encephalography (MEG) and particularly, non-invasive mapping methods such a Transcranial Magnetic Stimulation (TMS) will be described and the variability of FEF localization across individuals and mapping techniques will be discussed. In the second part of this review, we will address the role of the FEF. We will explore its involvement both in the physiology of fixation, saccade, pursuit and vergence movements and in associated cognitive processes such as attentional orienting, visual awareness and perceptual modulation. Finally in the third part, we will review recent evidence suggesting the high level of malleability and plasticity of these regions and associated networks to non-invasive stimulation. The exploratory, diagnostic and therapeutic interest of such interventions for the modulation and improvement of perception in 3D space will be discussed.

Scoping the Sharing Economy: Origins, Definitions, Impact and Regulatory Issues

Abstract: This report selectively draws on the systematic review of a large set of data sources, which is presented elsewhere, and comprises 430 secondary sources (Codagnone, 2016). The report also provides a critical overview of key analytical, empirical, and normative dimensions of the ‘sharing economy’. It reviews both the rhetorical and controversial debates currently surrounding the topics and the available empirical evidence in order to sharpen our understanding of relevant policy and regulatory issues. The broad umbrella term 'sharing economy' is critically assessed and a typology developed that identifies the commercial 'peer to peer' sharing economy as the main focus of both controversies and policy-relevant issues. Empirical evidence of the benefits and costs of the sharing economy and its implications for sustainability and employment is very limited and inconclusive, particularly as regards the European landscape. This critical review, hence, shows that, as yet, there are no unambiguous answers to some of the fundamental questions about the ‘sharing economy’. The available research is too limited and patchy to give us a comprehensive and coherent picture. This report’s main contribution is to clear some of the conceptual and empirical fog around the ‘sharing economy’ and to identify where possible answers might be found in the future. It is suggested that the definition of sharing platforms should focus on P2P activities, as most of the policy concerns are found there. These include regulatory and consumer protection issues resulting from the informal production of services, potentially unfair competition with formal B2C service providers, and questions related to dominance and market power of P2P platform operators as commercial businesses.

Learning online: massive open online courses (MOOCs), connectivism, and cultural psychology

Abstract: In this reflection, we discuss the connectivist conception of learning in Web 2.0 environments, which underpins the pedagogy of what are known as cMOOCs (connectivist massive open online courses). We argue that this conception of learning is inadequate and problematic, and we propose that cultural psychology is best suited to address the explanatory challenges that Web 2.0 poses on learning, and therefore, it is also best suited to provide massive open online courses with more adequate and less problematic pedagogy. We suggest two initial and general pedagogical principles based on cultural psychology upon which to begin building this new pedagogy for massive open online courses.
