Viestinnän strateginen rooli organisaatiossa : näkemyksiä viestinnän strategisesta luonteesta ja siihen vaikuttavista tekijöistä
2016
Viestinnän merkitys organisaatiossa korostuu dynaamisessa toimintaympäristössä, sillä viestintäammattilaisen ydinosaamiseen kuuluvat hyvät konfliktin hallintakyvyt sekä sidosryhmätaidot. Silti viestintäammattilaiset joutuvat edelleen paikoittain varjoon organisaation strategisista toimijoista puhuttaessa ja tämä saattaa johtaa esimerkiksi heikompaan budjetointiin sekä vähäisiin vaikuttamismahdollisuuksiin. Tutkimuksen tavoitteena oli lisätä ymmärrystä strategisen viestinnän käsitteestä ja tuoda tuoreita näkökulmia viestintäammattilaisten asemaan organisaatiossa. Tutkimuskysymyksissä pohdittiin viestintäammattilaisen strategista roolia, strategisen viestinnän määritelmää sekä viestintäammatt…
Inconsistencies in the pozzolanic strength activity index (SAI) for silica fume according to EN and ASTM
2014
Published version of an article in the journal: Materials and Structures. Also available from the publisher at: http://dx.doi.org/10.1617/s11527-014-0457-6 Open Access New supplementary cementitious materials claimed to possess pozzolan properties emerge frequently. This development is driven both by economic and environmental pressures. Properties of new materials are compared with those of materials already well known, such as silica fume. Several test methods are standardized for making such comparisons, regulated by both European (EN) and American (ASTM) standards. Standardization indicates that procedures are secured to make comparisons valid and informative. In this article the sensit…
Experimental Investigation on Stiffness and Strength of Single-Lap Z-Pinned Joints in a Laminated CFRP Stress-Ribbon Strip
2016
Carbon fiber-reinforced polymer (carbon-polymer) is an advanced lightweight composite material with high strength and excellent resistance to corrosion and fatigue. Over the past decades, application of fiber-reinforced polymers has been spread from the aerospace to other branches of industry such as automobile and civil engineering. Unidirectional carbon-polymers have a high potential for replacing steel in tensile members. Recently, the first carbonpolymer stress-ribbon bridge has been constructed in Germany. The non-laminated strip-loop carbon-polymer thin strips were used as the load bearing components in this bridge. In comparison with the laminated components, the applied cables are c…
Past, present, and future of green product innovation
2021
Firms are under constant pressure from various governmental and nongovernmental agencies to switch from conventional environmentally polluting products to green product innovations (GPIs). However, the relevant research pertaining to GPI has been published in a diverse set of journals that vary in their scope and readership and, therefore, the scholarly contribution to the topic remains largely fragmented. This study has utilised a systematic literature review approach to examine the literary corpus on GPI to paint a holistic picture of its different aspects. The content and thematic analysis of 85 studies resulted in the extraction of seven key research themes: organisational capabilities,…
Regional headquarters and foreign direct investment
2022
Headquarters (HQs) provide a wide range of services, playing a fundamental role in Foreign Direct Investment (FDI). We use the structural gravity equation to investigate the effect of regional HQs on three dimensions of FDI (number of foreign projects, capital investment, and jobs) at the country-pair-sector level. Furthermore, we explore two underlying mechanisms that help explain this relationship: financial constraints and informational costs and uncertainty. We find a positive effect of regional HQs on FDI, as well as intercountry and intersector spillovers. Our results are robust, accounting for HQ intensity, domestic investment, and endogeneity tests.
Primitives extraction based on structured-light images
2013
International audience; Geometric attributes such as curvature or surface orientation are additional information of the 3D points obtained after the scanning of an object. In the classic 3D chain, characterized by a sequential structure, these information are determined from the dense point cloud (from a 3D scanner). Then, they are used to reduce the amount of information and allows to obtain a simplified model. In this paper, we investigate the possibility to extract some geometric attributes, directly from 2D images obtained by the camera of a structured-light system.
Towards a Guidance System to Aid in the Dosimetry Calculation of Intraoperative Electron Radiation Therapy
2015
In Intraoperative Electron Radiation Therapy (IOERT), the lack of specific planning tools limits its applicability, the need for accurate dosimetry estimation and application during the therapy being the most critical. Recently, some works have been presented that try to overcome some of the limitations for establishing planning tools, though still an accurate guidance system that tracks, in real-time, the applicator and the patient is needed. In these surgical environments, the acquisition of an accurate 3D shape of the patient’s tumor bed in real-time is of high interest, as current systems make use of a 3D model acquired before the treatment. In this paper, an optical-based system is pre…
Who am I? : the teacher identity construction of student teachers
2015
Opettajaidentiteetti on tutkimusaiheena varsin ajankohtainen ja viime vuosina huomiota on aiempaa enemmän alettu kiinnittää myös opettajaopiskelijoiden ammatti-identiteettiin, sillä tämän rakennusprosessin osatekijät vaikuttavat varsin eri tavoin lopulliseen identiteettiin. Aiempien tutkimusten pohjalta voidaan huomata, että opettajaidentiteetin muodostumisprosessissa on useita eri osatekijöitä, jotka tässä tutkielmassa on jaettu kahteen faktoriryhmään: henkilökohtaisiin ja opettajankoulutuksellisiin faktoreihin. Kirjallisuuskatsauksen perusteella kävi myös ilmi, että useat opettajaopiskelijat kokevat ristiriitaa henkilökohtaisten näkemystensä ja opettajankoulutuksen painotuksen välillä. Tä…
Enabling and constraining family: young women building their educational paths in Tanzania
2015
For an increasing number of African girls and women, upgrading the level of education has become a strategy for life improvement. This paper analyses the role that family plays in enabling women's education and contributes to understanding on the interconnectivity of education, work and family in women's lives in collective societies. The analysis focuses on how young Tanzanian women perceive the role of family and education in their ‘youth task’, of becoming adult. The analysis is based on interviews with seven young Tanzanian women enrolled in non-formal secondary education and nine professional women enrolled in higher education. The results show that the women were determined to pursue …
Developing inclusive education policy and practice in Zanzibar : collaborative action research
2018
This doctoral dissertation, which consists of three interrelated sub-studies and an overarching summary, explores the inclusive education development process in Zanzibar, Tanzania. The purpose of the research is to contribute to the development of inclusive policies and practices in order to increase the presence, participation and achievement of all learners. The overarching research question investigated in this research was as follows: How is inclusive education developed in Zanzibar, and how can it be better integrated into the education system? This question was divided into six sub-questions. Each of the three interrelated sub-studies in this dissertation focused on specific sub-quest…
