Note about the concept of ‘Net Multipliers'
2002
International audience; Net multipliers, as introduced by Oosterhaven and Stelder (2002) accept outputs as entries instead of final demand. They are found by multiplying ordinary multipliers by the final demand ratio over the sector's output. This pragmatic solution suffers from ratio instability over time. The alternative net multipliers proposed here are based on the interpretation of the Leontief inverse matrix for the effects generated at each round. The new solution is not sensitive to the size of impacts. Now net multiplier is equal to the corresponding ordinary multiplier minus one, and the ordering of multipliers is unchanged.
A Task Execution Scheme for Dew Computing with State-of-the-Art Smartphones
2021
The computing resources of today’s smartphones are underutilized most of the time. Using these resources could be highly beneficial in edge computing and fog computing contexts, for example, to support urban services for citizens. However, new challenges, especially regarding job scheduling, arise. Smartphones may form ad hoc networks, but individual devices highly differ in computational capabilities and (tolerable) energy usage. We take into account these particularities to validate a task execution scheme that relies on the computing power that clusters of mobile devices could provide. In this paper, we expand the study of several practical heuristics for job scheduling including executi…
Progress towards innovative and energy efficient logic circuits
2020
Abstract The integration of superconductive nanowire logic memories and energy efficient computing Josephson logic is explored. Nanowire memories are based on the integration of switchable superconducting nanowires with a suitable magnetic material. These memories exploit the electro-thermal operation of the nanowires to efficiently store and read a magnetic state. In order to achieve proper memory operation a careful design of the nanowire assembly is necessary, as well as a proper choice of the magnetic material to be employed. At present several new superconducting logic families have been proposed, all tending to minimize the effect of losses in the digital Josephson circuits replacing …
The effects of mobile banking application user satisfaction and system usage on bank-customer relationships
2016
This study examines mobile banking (m-banking) application usage in Finland by linking it with customer-bank relationship development. Specifically, we examine how usage is related to relationship commitment, overall satisfaction, intention to recommend the bank and future intentions to remain with the bank. A survey was used to collect data from experienced mbanking application users. In total, 273 valid responses were received. The results support the hypotheses and reveal that user satisfaction with m-banking application usage has a strong positive association with usage of m-banking applications. Usage, in turn, was positively related to all examined bank-customer relationship related v…
Enabling a culture for IT services; the role of the IT infrastructure library
2016
Building on process management and service climate theories, this paper investigates the pertinent issues of whether firms that implement ITIL best practices for IT service management will also experience growth in their process management activities and IT service climate. First, ITIL practices imply that processes in the IT department should be managed on a daily basis; without process management, ITIL will fail beyond its initial implementation. Second, two of the main reasons for adopting ITIL are to become a service-oriented organisation and to deliver IT services that meet business needs. Thus, we hypothesise that as the implementation status of ITIL increases, process management and …
Human capital evaluation in knowledge-based organizations based on big data analytics
2020
Abstract Starting from a Human Capital Analysis Model, this work introduces an original methodology for evaluating the performance of employees. The proposed architecture, particularly well suited to the special needs of knowledge-based organizations, is articulated into a framework able to manage cases where data is missing and an adaptive scoring algorithm takes into account seniority, performance, and performance evolution trends, allowing employee evaluation over longer periods. We developed a flexible software tool that gathers data from organizations in an automatic way – through adapted connectors – and generates abundant results on the measurement and distribution of employees’ perf…
Model independent assertions for integration of heterogeneous schemas
1992
Due to the proliferation of database applications, the integration of existing databases into a distributed or federated system is one of the major challenges in responding to enterprises' information requirements. Some proposed integration techniques aim at providing database administrators (DBAs) with a view definition language they can use to build the desired integrated schema. These techniques leave to the DBA the responsibility of appropriately restructuring schema elements from existing local schemas and of solving inter-schema conflicts. This paper investigates the assertion-based approach, in which the DBA's action is limited to pointing out corresponding elements in the schemas an…
Bridging the Gap between Advanced Distributed Teaching and the Use of Learning Management Systems in the University Context
2007
The selection of appropriate learning management system (LMS) is critical for supporting advanced distributed teaching. A survey was targeted for understanding the features that the LMS offer for university teachers and to find if the advanced features of the LMS were utilized, The findings imply that there is a gap between the LMS tools for advanced distributed teaching and their use in the university context. The teachers using LMS were also found to be heterogeneous by their computer skills and LMS uses.
Improving situation awareness in crisis response teams
2016
In responding to an emergency, the actions of emergency response teams critically depend upon the situation awareness the team members have acquired. Situation awareness, and the design of systems to support it, has been a focus in recent emergency management research. In this paper, we introduce two interventions to the core processes of information processing and information sharing in emergency response teams to analyze their effect on the teams' situation awareness: (1) we enrich raw incoming information by adding a summary of the information received, and (2) we channel all incoming information to a central coordinator who then decides upon further distribution within the team. The eff…
Understanding cloud computing adoption issues: A Delphi study approach
2016
An exploratory ranking-type Delphi study and follow-up interviews were conducted.Important cloud computing adoption issues are identified, categorized and ranked.Three subpanels top-ranked issues from security, strategy and legal categories.A framework of inhibitors and drivers for cloud computing adoption is proposed.Recommendations to assist decision-makers in cloud computing adoption are proposed. This research paper reports on a Delphi study focusing on the most important issues enterprises are confronted with when making cloud computing (CC) adoption decisions. We had 34 experts from different domain backgrounds participated in a Delphi panel. The panelists were IT and CC specialists r…
