"Ermutige mich Deutsch zu sprechen" : Portfolio als Evaluationsform von mündlichen Leistungen

2007

Hannele Kara selvitti tutkimuksessaan kielisalkun soveltamismahdollisuuksia saksan kielen puhekulttuurin opettamisessa ja arvioinnissa perusopetuksen luokilla 8-­9 ja lukiossa. Kielisalkkutyöskentely pohjautuu yhteiseen eurooppalaiseen viitekehykseen, joka on suomalaisen kielikasvatuksen, opetussuunnitelmien, oppimateriaalien, kielikokeiden ja tutkintojen perusta. Karan väitöstutkimus liittyy valtakunnalliseen kielisalkkutyöskentelyn ohjaajakoulutukseen. – Suomalaiseen kielipedagogiikkaan tarvitaan uudenlaista arviointikulttuuria perinteisen numeroarvioinnin rinnalle, jotta kielten arvosanat ja todistukset olisivat kansainvälisesti vertailukelpoiset. Kielisalkkutyöskentely tukee erittäin hy…

Extensional deformations during Neogene chain building in Sicily

2010

ABSTRACT In the Madonie-Nebrodi Mts (Northern Sicily belt) both Mesozoic carbonate platform/basin-derived deformed successions and Neogene foredeep deposits outcrop. Thrust sheets piled-up southwards in thin-skin piggy-back sequence. The chain building process began during the Oligo-Miocene. The syntectonic deposits involved in the compressional tectonics give evidence that syn-sedimentary extensional faults developed during fold nucleation and amplification. Syn-sedimentary extensional faults affect the foredeep strata at different stratigraphic levels, which are bounded by unconformities. Normal faults and bedding show constant cut-off relationships and are progressively tilted youngwards…

Crowdsourcing as a mode of open innovation: Exploring drivers of success of a multisided platform through system dynamics modelling

2020

This article aims to explore drivers of success of a crowdsourcing platform. The study conceptualizes crowdsourcing as a mode of open innovation and places such a concept within the context of the sharing economy. Upon this framework, the paper analyses the case of InnoCentive, a successful crowdsourcing platform where innovation-driven organizations search for solutions to their R&D tasks. The system dynamics model frames main InnoCentive business processes and offers a causal perspective on the relationships between platform performance—in terms of users base—and resources structure. The discussion on simulation outputs is carried out through a dynamic performance management view of p…

Design principles for collaboration platforms for open education

2015

Increasing the current low uptake of Open Education Resources (OER) is a key challenge for researchers and practitioners in the field. User studies have shown that collaboration is a main success factor for successful open educational activities. However, effective collaboration in open educational contexts requires well planned processes and platforms supporting collaboration, in particular in physically distributed settings. We have been investigating the value of such platforms, their main features and user requirements to enable collaboration from immature ideas to completed resources. We used quantitative and qualitative research methods to collect insights from potential users of such…

Value Creation and Evolution of a Value Network: A Longitudinal Case Study on a Platform-as-a-Service Provider

2014

Current research on cloud computing emphasizes the important role of Platform-as-a-Service (PaaS) providers. However, little is known about how PaaS providers can offer value to the content providers and firms operating the platform. The findings demonstrate how a small PaaS provider in the cloud gaming market was able to develop a strong position in the value network by offering direct and indirect value to its partners. The findings also reveal how the firm developed its value network over fourteen years, from a complex network with several actors to a very simple value network which included only partners of prime importance. peerReviewed

Transformation of the Forest-based Bioeconomy by Embracing Digital Solutions

2017

This paper attempts to explore a new insight to both industrialized and growing economies by demonstrating a digital-driven creative disruption in the forest-based bioeconomy which is beginning to replace its conventional and narrow concept of a forest-blinded economy. Notwithstanding the potential broad cross-sectoral benefits to both industrialized and growing economies, natural environments and locality constraints and the incessant challenge of distance have impeded balanced development of this economy. However, driven by digital solutions the economy has taken big steps forward in recent years. Digitalization has enabled real-time end-to-end supply chain visibility, improved delivery a…

Towards enabling privacy preserving smart city apps

2016

Smart city applications are increasingly relying on personally identifiable data. A disclosure of such a data to a platform provider and possible 3rd parties represents a risk to the privacy of the application users. To mitigate the privacy risk, two-layer privacy-preserving platform architecture is introduced, wherein the personally identifiable information is dealt with at the inner layer (executed in a trusted environment), whereas only generic and personally unidentifiable information is made available to the apps at the outer layer of the architecture — e.g., in a form of app-specific events. The essential requirements for the platform are described, and the architectural implications …

Anticipation as Platform Power : The Temporal Structuring of Digital Everyday Life

2023

This article explores anticipation as a temporal structure in digital platforms. It contributes to the growing research of platformisation of everyday life by focusing on temporality as a central dimension of platform power, a key mechanism tying participants by structuring intimacies, socialities, and relations that platforms enable and engender. The article shows how the temporality of foreboding, prospecting and speculating about one’s own and other’s social media presence and actions permeates the user experience. Studying media diaries and interviews with participants from different social and occupational groups (politicians, actors, the unemployed, undocumented migrants), the article…

Survey of Research for Performance Measurement of Mobile Manipulators

2016

International audience; This survey provides the basis for developing research in the area of mobile manipulator performance measurement, an area that has relatively few research articles when compared to other mobile manipulator research areas. The survey provides a literature review of mobile manipulator research with examples of experimental applications. The survey also provides an extensive list of planning and control references as this has been the major research focus for mobile manipulators which factors into performance measurement of the system. The survey then reviews performance metrics considered for mobile robots, robot arms, and mobile manipulators and the systems that measu…
