Synchrotron x-ray transmission measurements and modeling of filters investigated for Athena
2020
International audience; Advanced Telescope for High-Energy Astrophysics is a large-class astrophysics space mission selected by the European Space Agency to study the theme "Hot and Energetic Universe." The mission essentially consists of a large effective area x-ray telescope and two detectors: the X-ray Integral Field Unit (X-IFU) and the Wide Field Imager (WFI). Both instruments require filters to shield from out-of-band radiation while providing high transparency to x-rays. The mission is presently in phase B; thus, to consolidate the preliminary design, investigated filter materials need to be properly characterized by experimental test campaigns. We report results from high-resolution…
Business model scaling and growth hacking in digital entrepreneurship
2023
Creating an innovative product and validating an innovative business model may not be enough for digital startups to be competitive. To grow fast and expand globally, digital startups need to innovate their business model during the scaling phase. A pragmatic approach has recently been proposed to support digital entrepreneurs engaging in business-model innovation during the scaling phase (i.e., business-model scaling), a strategy known as growth hacking. However, we know little about its theoretical grounding and how effective growth hacking is, as businesses lack methodologies to assess its effectiveness before committing resources and investments. To fill this gap, we developed a method …
Information Integration, Coordination Failures, and Quality of Prescribing
2020
Poor information flows hamper coordination, potentially leading to suboptimal decisions in health care. We examine the effects of a nationwide policy of information integration on the quality of prescribing. We use the rollout of an electronic prescribing system in Finland and prescription-level administrative data. We find no effect on the probability of co-prescribing harmful drug combinations in urban regions. In rural regions, this probability reduces substantially, by 35 percent. The effect is driven by prescriptions from unspecialized physicians and from multiple physicians. Improving the local information environment thus enhances coordination and narrows differences in the quality o…
Sākumskolas skolotāju mediju pratības un tās pilnveides izpēte izglītības digitalizācijas kontekstā
2018
Izglītības digitalizācijas kontekstā skolotāju mediju pratība kļūst arvien nozīmīgāka. Izglītība mūsdienu lietpratībai paredz, ka skolēniem būs pietiekami augsti attīstīta digitālā caurviju prasme. Lai palīdzētu skolēniem attīstīt un pilnveidot digitālās kompetences, skolotājiem pašiem jābūt ar augstu mediju pratības un digitālās kompetences līmeni. Sākumizglītības posmā skolēniem tiek veidotas pamata prasmes, tāpēc maģistra darba mērķis ir noskaidrot sākumskolas skolotāju mediju kompetenci un tās pilnveides iespējas. Analizējot normatīvos dokumentus, tika noskaidrots, ka šobrīd Latvija un Eiropas Savienība iegulda daudz līdzekļu izglītības digitalizācijā. Izpētot teorētisko literatūru un v…
Towards a scenario of virtual mental health environments for school-aged children
2017
This study explores student teachers’ future design scenarios focusing on promoting children’s mental health literacy through virtual reality (VR) environments. VR use is on the verge of many breakthroughs in several areas of lived experience. One such area pertains to educational contexts. Student teachers were chosen as the subjects of this study due to the likelihood that they will be the primary users and disseminators of these emerging technologies in educational contexts. The students created five types of future scenarios that contained different environments and activity modes, including those that are still not yet feasible to realize with current technological capabilities. The ai…
Role of Acquisition Intervals in Private and Public Cloud Storage Costs
2014
The volume of worldwide digital content has increased nine-fold within the last five years, and this immense growth is predicted to continue in the foreseeable future to reach 8 ZB by 2015. Traditionally, organizations proactively have built and managed their private storage facilities to cope with the growing demand for storage capacity. Recently, many organizations have instead welcomed the alternative of outsourcing their storage needs to the providers of public cloud storage services due to the proliferation of public cloud infrastructure offerings. The comparative cost-efficiency of these two alternatives depends on a number of factors, such as the prices of the public and private stor…
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…
Online activity traces around a "Boston bomber"
2013
This paper describes traces of user activity around a alleged online social network profile of a Boston Marathon bombing suspect, after the tragedy occurred. The analyzed data, collected with the help of an automatic social media monitoring software, includes the perpetrator's page saved at the time the bombing suspects' names were made public, and the subsequently appearing comments left on that page by other users. The analyses suggest that a timely protection of online media records of a criminal could help prevent a large-scale public spread of communication exchange pertaining to the suspects/criminals' ideas, messages, and connections.
Elementary Math to Close the Digital Skills Gap
2018
All-encompassing digitalization and the digital skills gap pressure the current school system to change. Accordingly, to ’digi-jump’, the Finnish National Curriculum 2014 (FNC-2014) adds programming to K-12 math. However, we claim that the anticipated addition remains too vague and subtle. Instead, we should take into account education recommendations set by computer science organizations, such as ACM, and define clear learning targets for programming. Correspondingly, the whole math syllabus should be critically viewed in the light of these changes and the feedback collected from SW professionals and educators. These findings reveal an imbalance between supply and demand, i.e., what is ove…
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…
