Cross-Talk Correction Method for Knee Kinematics in Gait Analysis Using Principal Component Analysis (PCA): A New Proposal
2014
International audience; Background: In 3D gait analysis, the knee joint is usually described by the Eulerian way. It consists in breaking down the motion between the articulating bones of the knee into three rotations around three axes: flexion/extension, abduction/adduction and internal/external rotation. However, the definition of these axes is prone to error, such as the "cross-talk'' effect, due to difficult positioning of anatomical landmarks. This paper proposes a correction method, principal component analysis (PCA), based on an objective kinematic criterion for standardization, in order to improve knee joint kinematic analysis. Methods: The method was applied to the 3D gait data of …
Food loss and waste in food supply chains. A systematic literature review and framework development approach
2021
Abstract This study examines the state of the art of the literature in the domain of food loss and waste (FLW) in food supply chains (FSC). The authors used a systematic literature review (SLR) approach to examine and synthesise the findings of the existing literature to identify the key research themes, research gaps and avenues of future research on FLW in FSC. To this end, this SLR considered 152 articles relevant for the review. The authors uncovered the extant literature in the domain by presenting the research profile of the selected studies, along with thematic analysis. The authors identified eight key themes from the extant literature. The themes range from factors responsible for …
An analysis of co‐operative agreements from a knowledge‐based perspective: an integrative conceptual framework
2002
The last decade has been witness to an unprecedented growth in the number of alliances between companies. This growing importance of interfirm co‐operation, together with its inherent complexity, have generated a progressive interest in the study of this phenomenon, which has materialised in a vast but fragmented literature concerning it. As a response to the demands which these conditions pose, we have endeavoured to develop a conceptual framework which, from a knowledge‐based and learning perspective, integrates an extensive series of contributions and concepts for the study of the processes of co‐operation between companies. As distinctive features, our conceptual framework proposal sets…
A Framework for Small Group Support in Online Collaborative Learning - Combining Collaboration Scripts and Online Tutoring
2017
Many learners experience difficulties engaging in collaborative learning activities online. Computer-supported collaborative learning (CSCL) scripts have been implemented to support online learners. Collaboration scripts have shown much potential in facilitating students’ general collaboration skills. However, reported effects of collaboration scripts on domain-specific knowledge acquisition have been less positive. In this paper, I suggest an alternative framework for supporting CSCL learners by combining collaboration scripting and online tutoring. While collaboration scripts can facilitate the acquisition of general collaboration skills, the online tutor is capable of monitoring and asse…
Integrating Individual and Intra-organizational Learning for Calibration of Organization’s Performance
2021
The pragmatic literature review explores the significance of individual and intra-organizational learning for organization’s performance. Literature review depicts topic actuality, conceptual contribution, research methods and scientific discussions. The relativity of learning for individuals and organization have been evaluated on behalf of selected scientific papers. The articles reviewed for developing literature review have shown similarities of subject knowledge. The comparative analysis of conceptual framework is based on examination of experiments and modelling documented in previous research. Learning is considered as a process of transferring skills and knowledge from recognized in…
Explorando la divulgación de información integrada por universidades colombianas. Un análisis de páginas web basado en el marco del IIRC
2021
La información integrada se presenta como un fenómeno de reciente auge que permite a diversas organizaciones informar de una manera simplificada pero completa sobre su gestión respecto a diversos tipos de capitales. Aunque predominantemente se ha desarrollado en las empresas privadas, en el ámbito internacional viene reconociéndose que otro tipo de organizaciones como las universidades, divulgan esta información o cuentan con la necesidad y el potencial para ello. Este trabajo tiene como objetivo analizar en qué medida la información solicitada para construir un reporte integrado de acuerdo con los requerimientos del Marco Conceptual del IIRC, ya está revelada en internet por las universida…
Tracing discursive processes of shared knowledge construction in a technology-enhanced higher education setting
2013
This study focused on combining both the group- and individual-level analyses in studying a collaborative activity in technology-enhanced interactions in a higher education setting. The aim was to make visible, with empirical examples, the quality of the students' web-based discussions and trace the route for shared understanding. By quantifying various communicative functions, the analysis provided general knowledge on the quality and purpose of the discussion in the group and highlighted the different functional positions each student had within the group. However, only a detailed interpretative analysis of the relationships between specific thematic contents, communicative functions, and…
Learning outcomes in the field of human resource management in business administration studies in the context of implementation of European Qualifica…
2018
The study carried out in this paper involves the analysis of the content of the competencies in the field of human resource management in order to adquire the key competences of the students that will be alligned with the needs of the labor market according to the European Qualifications Framework (EQF). The method of comparative analysis and case study methodology is used in the paper. This research compares teaching courses that include the acquisition of competences in the field of human resource management in business administration studies, one of the key areas of contemporary management, with examples from the Departament of Economics and Business Economics of the University of Dubrov…
What Can We Learn from Theoretical Considerations and Empirical Evidence on Learning in Higher Education? Implications for an Interdisciplinary Resea…
2019
Since the development of the hypertext markup language (HTML), a myriad of data from different sources has become increasingly cross-linked, resulting in entire information landscapes; more than 21 billion electronic devices (Web 4.0) will be in use by 2020. Access to and processing of multimedia content and unverified and algorithmically preselected information are constitutive elements of learning in the Internet Age. As learning occurs in- and outside of formal higher education institutions and cannot be explained by educational or technological factors alone, it is a crucial cross-disciplinary topic, equally important for all areas of science and education. Yet, research on learning in …
Open Educational Resources’ impact and outcomes: The essence of OpenKnowledge and its social contribution
2018
This article identifies the main social contributions of Open Educational Resources (OERs), their impact and the results of several initiatives related to them. Based on a theoretical and reflexive framework, we analyze the evolution of business models around OERs, their contribution to open knowledge and the common educational policies related to this phenomenon. Finally, we point out the new horizons and models of knowledge based on OERs. Design/methodology/approach: This study utilizes a theoretical and conceptual framework based on references coming from journals with an impact factor, complemented with quotes by important authors and OER representatives. The review offers a conceptual …
