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.
How does brand-related user-generated content differ across social media? Evidence reloaded
2019
Abstract In light of the relevant changes in the social media environment in recent years, this paper extends the theoretical framework of user-generated content (UGC) dimensions and updates evidence on how brand-related UGC characteristics vary across social media. Using content analysis and statistical analysis of frequencies, we compare how different social media (Facebook, Twitter, and YouTube) shape twelve important UGC dimensions. Our findings suggest that, by flattening the differences on visual and richer content, the recent trends have made Facebook and Twitter more similar to YouTube on certain brand-related UGC dimensions (e.g., self-presentation, brand centrality, brand recommen…
A Characterization of Quintic Helices

Quantum chemical meta-workflows in MoSGrid
2014
Quantum chemical workflows can be built up within the science gateway Molecular Simulation Grid. Complex workflows required by the end users are dissected into smaller workflows that can be combined freely to larger meta-workflows. General quantum chemical workflows are described here as well as the real use case of a spectroscopic analysis resulting in an end-user desired meta-workflow. All workflow features are implemented via Web Services Parallel Grid Runtime and Developer Environment and submitted to UNICORE. The workflows are stored in the Molecular Simulation Grid repository and ported to the SHIWA repository. © 2014 John Wiley & Sons, Ltd.
Software-as-a-Service in the Telecommunication Industry: Problems and Opportunities
2010
This paper examines the telecommunication software market and the adoption of topical Software-as-a-Service (SaaS) model in this vertical market. The aim of this paper is to estimate which telecommunication software products are likely to be provided as a Service, and to examine the potential factors disallowing SaaS adoption. The set aim is pursued by studying both the supplying software vendors and the communication service providers (CSP) as customers. A set of thematic interviews, software industry statistics and information disclosed by the software vendors are used in the analysis. The results of the analysis reveal challenges in adopting SaaS for telecommunication software as well as…
Current Software-as-a-Service Business Models: Evidence from Finland
2012
This paper characterizes the business models of Software-as-a-Service (SaaS) firms based on their value proposition, customer segments, revenue streams, and customer relationship, and analyzes interconnections of these business model elements. The target set of 163 Finnish SaaS and ASP firms was first compared to other software firms and then clustered into four clusters based on indicator data of their business model elements. The comparison reveals that the SaaS and ASP firms have smaller customer and transaction sizes than software firms in general. The resulting classification reveals two different configurations, a pure-play SaaS model and an enterprise SaaS model, and the typical fact…
Adoption of Open Source Software and Software-as-a- Service Models in the Telecommunication Industry
2011
A case research is carried out on adoption of open source software (OSS) and software-as-a-service (SaaS) in the telecommunication industry. The study was conducted to examine the types of software deployed as OSS and SaaS and the conditions of adopting OSS and SaaS. Findings of the case study indicate that industry-specific software is not developed as OSS or deployed in SaaS mode. Based on the findings, we also arrive at conclusion: Adoption is hindered by specificity of processes and technology interfaces.
Examining Business Models of Software-as-a-Service Firms
2013
The paper focuses the attention to different business models and intended strategic aims of the firms providing Software-as-a-Service (SaaS). SaaS vendors have been said to challenge the business practices of the existing vendors providing proprietary or customer-specific solutions. The current studies on the topic have shown that SaaS is different from preceding software business models, but consider and emphasize SaaS business model as an invariable configuration. This case study compares two SaaS firms with different backgrounds and reveals characteristics of two very different SaaS business models. The findings indicate that along with SaaS vendors providing only standard software appli…
Comparison of different revenue models in SaaS
2012
Cloud computing brings new possibilities for software firms to sell their products within a Software-as-a-Service (SaaS) model. However, although SaaS provides new revenue models, it may not easily achieve a profitable revenue stream. For customers, SaaS promises cost savings related to IT expenses. However, it may be difficult to estimate which revenue model will be best for a given situation. In this paper I present the common revenue models used in SaaS, examining their advantages and disadvantages from the point of view of the software provider and the customer.

Robustness in railway transportation scheduling
2008
Railway scheduling has been a significant issue in the railway industry. Over the last few years, numerous approaches and tools have been developed to compute railway scheduling. However, robust solutions are necessary to absorb short disruptions. In this paper, we present the robustness problem from the point of view of railway operators and we give some guidelines to measure robustness in timetabling. We have developed some formulae to compare robustness between two timetables based on the study of railway infrastructure topology and buffer times. Thus, each buffer time is pondered by some factors such as tightest tracks, number of subsequent trains, remaining stations, etc. This method i…
