An Information system design product theory for the abstract class of integrated requirements and delivery management systems
2014
Information and Communications Technology-enabled international sourcing of software-intensive systems and services (eSourcing) is increasingly used as a means of adding value, reducing costs, sharing risks, and achieving strategic aims. To maximally reap the benefits from eSourcing and to mitigate the risks, providers and clients have to be aware of and build capabilities for the eSourcing life-cycle. China is in a position to become a superpower for eSourcing service provisioning, but most Chinese eSourcing service providers are small or medium-sized and typically work for larger intermediaries instead of end-clients, limiting their business and capabilities development. The extant litera…
A Cooperative Coevolution Framework for Parallel Learning to Rank
2015
We propose CCRank, the first parallel framework for learning to rank based on evolutionary algorithms (EA), aiming to significantly improve learning efficiency while maintaining accuracy. CCRank is based on cooperative coevolution (CC), a divide-and-conquer framework that has demonstrated high promise in function optimization for problems with large search space and complex structures. Moreover, CC naturally allows parallelization of sub-solutions to the decomposed sub-problems, which can substantially boost learning efficiency. With CCRank, we investigate parallel CC in the context of learning to rank. We implement CCRank with three EA-based learning to rank algorithms for demonstration. E…
Guidelines for improving the contextual relevance of field surveys: the case of information security policy violations
2014
The information systems (IS) field continues to debate the relative importance of rigor and relevance in its research. While the pursuit of rigor in research is important, we argue that further effort is needed to improve practical relevance, not only in terms of topics, but also by ensuring contextual relevance. While content validity is often performed rigorously, validated survey instruments may still lack contextual relevance and be out of touch with practice. We argue that IS behavioral research can improve its practical relevance without loss of rigor by carefully addressing a number of contextual issues in instrumentation design. In this opinion article, we outline five guidelines – …
Customer Feedback System : Evolution Towards Semantically-enchanced Systems
2015
The digital economy requires services be created in nearly real time – while continuously listening to the customer. Managing and analysing the data collected about products and customers become very critical. Successful companies must collect data regarding customer behaviour in a sensible manner, understand their customers and engage in constant interaction with them. Nowadays, having a huge data storage capacity, everyone collects data and hopes that it will be useful someday. But, it is frustrating when you do not know whether something useful will come out of it. It is not a problem to collect data, but it is very difficult to analyse it. To utilize the data they collect and analyse cu…
On optimal relay placement for improved performance in non-coverage limited scenarios
2014
Low power nodes have been a hot topic in research, standardization, and industry communities, which is typically considered under an umbrella term called heterogeneous networking. In this paper we look at the problem of deploying optimally low power nodes in the context of relay networking, when an operator connects low power nodes (or small cells) via the wireless backhaul that uses the same spectrum and the same wireless access technology. We present an analytical model that can calculate optimal coordinates for low power nodes based on the input parameters, such as preferred number of nodes, their transmission power, parameters of the environment etc. The analytical calculations are comp…
Industrial Citizenship, Cosmopolitanism and European Integration
2014
Abstract. There has been an explosion of interest in the idea of European Union citizenship in recent years, as a defining example of postnational cosmopolitan citizenship potentially replacing, or at least layered on top of national citizenships. We argue this form of EU citizenship undermines industrial citizenship, which is a crucial support for the egalitarianism and social solidarity on which other types of citizenship are based. Because industrial citizenship arises from collectivities based in class identities and national institutions, it depends on the nation state erritorial order and the social closure inherent in this. EU citizenship in its current ‘postnational’ form is realize…
Quality of educational dialogue and association with students’ academic performance
2018
The study used a mixed-methods approach to examine the associations between the quality of educational dialogue and students' academic performance and to analyse what kinds of dialogic teaching patterns of different levels of quality can be identified in classroom lessons. A total of 158 Grade 6 lessons were video-recorded, and the quality of the educational dialogue was assessed using the Classroom Assessment Scoring System-Secondary (CLASS-S) observational instrument. Multilevel modelling indicated that the quality of educational dialogue was positively associated with students’ academic performance (grades) in language arts and physics/chemistry. Qualitative analysis was subsequently use…
Educación XX1 : revista de la Facultad de Educación
2019
Los avances tecnológicos han provocado que el ámbito de la educación se vea influenciado por la aparición de nuevos modelos de enseñanza y aprendizaje mediados por la gran cantidad de recursos digitales y dispositivos electrónicos que cuenta hoy el profesorado. Uno de los enfoques metodológicos que está emergiendo como consecuencia de la innovación educativa es el flipped learning. Este modelo de enseñanza y aprendizaje se sustenta en la idea de que los discentes puedan visualizar y trabajar los contenidos de las próximas sesiones presenciales en el aula fuera del entorno académico, con la finalidad de dedicar el mayor tiempo posible en clase a la resolución de problemas y al despliegue de …
Are Virtues Shaped by National Cultures or Religions?
2012
The present paper examines the relative influence of religion and nation on conceptions of virtues. In a first study, conducted in the Netherlands, 926 respondents of different profession, age, sex, and religious background rank ordered a list of 15 virtues. A comparison of Dutch Muslims and non-Muslims showed a remarkably high resemblance in their ratings of virtues. Only faith was rated as being much more important by Muslims than by non-Muslims. In the second study, the influence of national cultures was examined. Adults (N = 795) from two culturally relatively similar countries, Germany and the Netherlands, and from Spain rated the same list of virtues. Crossnational differences between…
Dynamics in Interaction in Bilingual Team Teaching: Examples from a Finnish Preschool Classroom
2018
The current study aims to explore team teaching as it is manifested in bilingual interactional patterns in a preschool classroom in Finland. The data was collected in a preschool classroom where a bilingual pedagogy in Finnish (majority language) and Swedish (minority language) was implemented with monolingual Finnishspeaking children. Video recordings were made while two teachers with different predefined language roles were team teaching a class of 20 children during two circle times. A two-level analytic model was developed: on the macro level activity types, participant roles (type of leadership) and language allocation (the teachers’ relative use of Finnish and Swedish) were identified…
