    An integrated approach for analysing and assessing the performance of virtual learning groups

    Get PDF
    Collaborative distance learning involves a variety of elements and factors that have to be considered and measured in order to analyse and assess group and individual performance more effectively and objectively. This paper presents an approach that integrates qualitative, social network analysis (SNA) and quantitative techniques for evaluating online collaborative learning interactions. Integration of various different data sources, tools and techniques provides a more complete and robust framework for group modelling and guarantees a more efficient evaluation of group effectiveness and individual competence. Our research relies on the analysis of a real, long-term, complex collaborative experience, which is initially evaluated in terms of principled criteria and a basic qualitative process. At the end of the experience, the coded student interactions are further analysed through the SNA technique to assess participatory aspects, identify the most effective groups and the most prominent actors. Finally, the approach is contrasted and completed through a statistical technique which sheds more light on the results obtained that far. The proposal draws a well-founded line toward the development of a principled framework for the monitoring and analysis of group interaction and group scaffolding which can be considered a major issue towards the actual application of the CSCL proposals to real classrooms.Peer ReviewedPostprint (author's final draft

    Ethics in tax practice: A study of the effect of practitioner firm size

    Get PDF
    While much of the empirical accounting literature suggests that, if differences do exist, Big Four employees are more ethical than non-Big Four employees, this trend has not been evident in the recent media coverage of Big Four tax practitioners acting for multinationals accused of aggressive tax avoidance behaviour. However, there has been little exploration in the literature to date specifically of the relationship between firm size and ethics in tax practice. We aim here to address this gap, initially exploring tax practitioners’ perceptions of the impact of firm size on ethics in tax practice using interview data in order to identify the salient issues involved. We then proceed to assess quantitatively whether employer firm size has an impact on the ethical reasoning of tax practitioners, using a tax context-specific adaptation of a well-known and validated psychometric instrument, the Defining Issues Test

    Ontologies on the semantic web

    As an informational technology, the World Wide Web has enjoyed spectacular success. In just ten years it has transformed the way information is produced, stored, and shared in arenas as diverse as shopping, family photo albums, and high-level academic research. The “Semantic Web” was touted by its developers as equally revolutionary but has not yet achieved anything like the Web’s exponential uptake. This 17 000 word survey article explores why this might be so, from a perspective that bridges both philosophy and IT

    Sensemaking on the Pragmatic Web: A Hypermedia Discourse Perspective

    Get PDF
    The complexity of the dilemmas we face on an organizational, societal and global scale forces us into sensemaking activity. We need tools for expressing and contesting perspectives flexible enough for real time use in meetings, structured enough to help manage longer term memory, and powerful enough to filter the complexity of extended deliberation and debate on an organizational or global scale. This has been the motivation for a programme of basic and applied action research into Hypermedia Discourse, which draws on research in hypertext, information visualization, argumentation, modelling, and meeting facilitation. This paper proposes that this strand of work shares a key principle behind the Pragmatic Web concept, namely, the need to take seriously diverse perspectives and the processes of meaning negotiation. Moreover, it is argued that the hypermedia discourse tools described instantiate this principle in practical tools which permit end-user control over modelling approaches in the absence of consensus

    Aligning anti-money laundering, combating of financing of terror and financial inclusion : Questions to consider when FATF standards are clarified

    Full text link
    Purpose &ndash; The purpose of this paper is to identify key questions that should be addressed to enable the Financial Action Task Force (FATF) to provide guidance regarding the alignment of anti-money laundering, combating of financing of terror and financial inclusion objectives.Design/methodology/approach &ndash; The paper draws on relevant research and documents of the FATF to identify questions that are relevant to consider when it formulates guidance regarding the alignment between financial integrity and financial inclusion objectives.Findings &ndash; The FATF advises that its risk-based approach enables countries and institutions to further financial inclusion. It is, however, not clear what the FATF means when its uses the terms &ldquo;risk&rdquo; and &ldquo;low risk&rdquo;. It is also unclear whether current proposals for financial inclusion regulatory models will necessarily limit money laundering (ML) aswell as terror financing risks to levels that can be described as &ldquo;low&rdquo;. The FATF will need to clarify its own thinking regarding low money laundering and low terror financing risk before it will be able to provide clear guidance to national regulators and financial institutions.Originality/value &ndash; This paper was drafted to inform current FATF discussions regarding guidance on financial inclusion. The questions are relevant to all stakeholders in financial regulation.<br /

    Race, Crime, and Institutional Design

    Minorities are gravely overrepresented in every stage of the criminal process--from pedestrian and automobile stops, to searches and seizures, to arrests and convictions, to incarceration and capital punishment. While racial data can provide a snapshot of the current state of affairs, such information rarely satisfies questions of causation, and usually only sets the scene for normative theory

    Principled Approaches in Online Teacher Education: Migrating SIT’s Masters in Teaching Program

    Get PDF
    Delivery methods for teacher education at the post-graduate level are changing to accommodate in-service professionals and take advantage of technology. To shift the SIT Graduate Institute’s Masters in Teaching program to a low-residency format, an evaluation of underlying principles in teacher education, online education and the MAT program itself is necessary in order to preserve the integrity of the program and ensure success in this new format. Within the context of these principles and an analysis of a sampling of program areas, recommendations are provided
