    BioCloud Search EnGene: Surfing Biological Data on the Cloud

    Get PDF
    The massive production and spread of biomedical data around the web introduces new challenges related to identify computational approaches for providing quality search and browsing of web resources. This papers presents BioCloud Search EnGene (BSE), a cloud application that facilitates searching and integration of the many layers of biological information offered by public large-scale genomic repositories. Grounding on the concept of dataspace, BSE is built on top of a cloud platform that severely curtails issues associated with scalability and performance. Like popular online gene portals, BSE adopts a gene-centric approach: researchers can find their information of interest by means of a simple “Google-like” query interface that accepts standard gene identification as keywords. We present BSE architecture and functionality and discuss how our strategies contribute to successfully tackle big data problems in querying gene-based web resources. BSE is publically available at: http://biocloud-unica.appspot.com/

    Towards a Novel Cooperative Logistics Information System Framework

    Get PDF
    Supply Chains and Logistics have a growing importance in global economy. Supply Chain Information Systems over the world are heterogeneous and each one can both produce and receive massive amounts of structured and unstructured data in real-time, which are usually generated by information systems, connected objects or manually by humans. This heterogeneity is due to Logistics Information Systems components and processes that are developed by different modelling methods and running on many platforms; hence, decision making process is difficult in such multi-actor environment. In this paper we identify some current challenges and integration issues between separately designed Logistics Information Systems (LIS), and we propose a Distributed Cooperative Logistics Platform (DCLP) framework based on NoSQL, which facilitates real-time cooperation between stakeholders and improves decision making process in a multi-actor environment. We included also a case study of Hospital Supply Chain (HSC), and a brief discussion on perspectives and future scope of work

    From planning the port/city to planning the port-city : exploring the economic interface in European port cities

    Get PDF
    In last three decades, planning agencies of most ports have institutionally evolved into a (semi-) independent port authority. The rationale behind this process is that port authorities are able to react more quickly to changing logistical and spatial preferences of maritime firms, hence increasing the competitiveness of ports. Although these dedicated port authorities have proven to be largely successful, new economic, social, and environmental challenges are quickly catching up on these port governance models, and particularly leads to (spatial) policy ‘conflicts’ between port and city. This chapter starts by assessing this conflict and argue that the conflict is partly a result of dominant—often also academic—spatial representations of the port city as two separate entities. To escape this divisive conception of contemporary port cities, this chapter presents a relational visualisation method that is able to analyse the economic interface between port and city. Based on our results, we reflect back on our proposition and argue that the core challenge today for researchers and policy makers is acknowledging the bias of port/city, being arguably a self-fulfilling prophecy. Hence, we turn the idea of (planning the) port/city conflicts into planning the port-city’s strengths and weaknesses

    The professionalization of festival organizations : A relational approach to knowledge management

    Get PDF
    In this article we examine the emergence of knowledge management (KM) within the professionalisation of festivals and events. The growing complexity of festival management places pressure on organisations to effectively manage ‘knowledge’ in order to succeed. Knowledge is commonly conceptualised as information that can be stored or itemised through checklists. We offer an alternative conceptualisation of KM as a relational construction shaped by the organisational culture and structure. We develop this relational approach through a case study of the Queensland Music Festival (QMF) to examine the construction of KM roles and responsibilities. Our ethnographic research and qualitative analysis identifies how QMF implicitly utilises chief knowledge officer, knowledge broker, and knowledge worker roles. These roles were successfully performed over a short duration and yet they were not defined or explicitly stated. We discuss how the culture and spatial organisation of work teams contributed to a collective understanding of the value of sharing and creating knowledge. With growing professionalisation we argue that festival organisations will increasingly develop a more self-conscious awareness of the significance of KM language and practice. The findings will enable festival managers to better understand how KM processes are embedded within an organisational culture and contribute to organisational learning.Peer reviewedFinal Accepted Versio

    Architecture for Provenance Systems

    No full text
    This document covers the logical and process architectures of provenance systems. The logical architecture identifies key roles and their interactions, whereas the process architecture discusses distribution and security. A fundamental aspect of our presentation is its technology-independent nature, which makes it reusable: the principles that are exposed in this document may be applied to different technologies
