A fog-assisted system to defend against Sybils in vehicular crowdsourcing
2022
Technological advancements in vehicular transportation systems have led to the growth of novel paradigms, in which vehicles and infrastructures collaborate to infer high-level knowledge about phenomena of interest. Vehicular Social Network (VSN) is one such paradigm in which vehicular network entities are considered as part of an Online Social Network (OSN), paving the way for new services derived from social context. Although vehicular crowdsourcing has tremendous benefits, its deployment in real systems requires to solve important challenges including defense against Sybil attacks. This paper proposes a novel fog-assisted system that uses SybilDriver to minimize the presence of Sybil enti…
Transcribing the "Estoria de Espanna" using crowdsourcing: Strategies and aspirations
2015
This paper examines the specific strategies for recruitment and retention of volunteer transcribers in use in two collaborative transcription projects: Transcribe Bentham (University College, London) and the Estoria de Espanna Digital Project (University of Birmingham). The aim of the paper is to review the strategies used by Transcribe Bentham, a more mature crowdsourced electronic transcription project, with a view to informing the strategies put into place in the Estoria project, which has started transcribing using crowdsourcing more recently. The paper discusses the difficulties faced by crowdsourced electronic transcription projects and how these have been and are being resolved in th…
Intellectual property management between buyer-supplier in the crowdsourcing context
2017
In this paper we investigate the antecedents of buyers’ decisions related to the management of the IPR generated by the suppliers in crowdsourcing contests. Leveraging on Property Rights Theory and interview data, we examine how contest’ attributes affect two buyers’ decisions about (1) whether to define an IPR arrangement ex-ante or negotiating it ex-post with the winning supplier; (2) the choice between strong or weak ownership levels of the IPR arrangement. To test the developed hypotheses, we build a dataset of 819 contests broadcasted on InnoCentive (from 2010 to 2016). Our findings contribute to both the operations management and the crowdsourcing literatures.
Supplier switching decisions
2007
Abstract In order to maximize profit, a buying firm should continuously search for and access sources which offer more favorable prices. While the literature is replete with works on the formation and development of buyer–supplier relationships, there is surprisingly only scarce research on the termination of such relationships and supplier switching. Using the concept of switching costs in a principal-agent framework, we at first analyze whether a firm switches the entire or a partial quantity to an alternative supplier when there is either symmetric or asymmetric information about the alternative supplier’s cost structure. Information asymmetry results in inert supplier switching decision…
Operations & Maintenance Business Model Transformation—Multiple Case Studies
2014
Capital goods companies’ service offering has been mainly to provide spare parts and maintenance work. In search of growth, these companies have expanded to new areas, such as Operations & Maintenance. Instead of operating and maintaining e.g. production processes itself, a customer can outsource a wide variety of managed services based on agreed service levels. There has been a special focus on global information management know-how, governance, process know-how, physical assets, and spare and wear parts. In order to get a good coverage of case studies, we selected five large global suppliers and two customer companies in telecommunication, energy, mining, and pulp and paper business. By i…
Cloud Sourcing and Paradigm Shift in IT Governance: Evidence from the Financial Sector
2020
In the digital age, organizations are increasingly shifting their applications, services and infrastructures to the cloud to enhance business agility and reduce IT-related costs. However, in moving applications and data to cloud resources organizations face new risks of privacy violations. To manage this risk, organizations need to be fully aware of threats and vulnerabilities affecting their digital re-sources in cloud. Although some previous studies have focused on the emerging challenges of cloud adoption to governance and control, we know little regarding the paradigm shifts in IT governance processes and practices. To address this gap, we conducted an exploratory case study in two larg…
A Model for Digital Archival of Municipal Documents
2006
While outsourcing IT infrastructure and various IT functions is common, outsourcing the digital archival of municipal documents has not been realized. The reasons for this include the complexity of operations, the lack of models complying with governmental regulation on archival as well as conflicting requirements on the security of sensitive information and public access. This paper presents a case where a municipality aims at outsourcing in a pilot project supported by researchers in project Kunda. Project Kunda applies a model utilizing a combination of contemporary standards, technologies and research results to achieve a replicable way to outsource the digital archival of municipal doc…
Crowdboard: Augmenting in-person idea generation with real-time crowds
2017
Online crowds can help infuse creativity into the design process, but traditional strategies for leveraging them, such as large-scale ideation platforms, require time and organizational effort in order to obtain results. We propose a new method for crowd-based ideation that simplifies the process by having smaller crowds join in-person ideators during synchronous creative sessions. Our system Crowdboard allows online crowds to provide real-time creative input during early-stage design activities, such as brainstorming or concept mapping. The system enables in-person ideators to develop ideas on a physical or digital whiteboard which is augmented with real-time creative input from online par…
The role of IPR arrangements in the crowdsourcing for innovation contest: an empirical investigation of the Innocentive challenges
2017
In this study, we identify three different Intellectual Property Right arrangements- strong IPR (acquiring an IP), weak IPR (licensing agreement) and flexible IPR. Integrating Property Rights Theory and the open innovation literature, we propose that specific challenge attributes affect the seekers organizations’ choice between alternative IPR arrangements and how this choice, in turn, affects the self-selection of external solvers into solving the problem. We collected multi-source, interview data with open innovation directors and a unique data set of 819 closed and awarded challenges broadcasted on InnoCentive platform from 2010 to 2016. Our findings contribute to the emerging literature…
eWOM in reward-based crowdfunding platforms: a behavioral approach
2020
[EN] Electronic word of mouth (eWOM) plays a crucial role in influencing purchasing decisions of consumers in situations governed by asymmetric information. In this context, investors in reward-based crowdfunding platforms might modify their purchasing intentions according to recommendations of peers and/or experts. The goal of this paper is to analyze the power of eWOM to shape consumers’ purchasing decisions. We do so by conducting an experiment through Amazon Mechanical Turk (AMT). This online experimental tool allows for an instant access to a large and culturally diverse subject pool, facilitating behavioral research requiring large amounts of subjects. By recreating a reward-based cro…
