Sustainability initiatives and the stakeholders involved : a case study of the GOLDEN Project and the electric utility industry
2017
This piece of research focuses primarily on which are the main types of sustainability initiatives within the electric utility sector with direct attention on five companies being Eletrobras, Rheinisch-Westfälisches Elektrizitätswerk AG, Fortum, Copel and Edison. Additionally this research looks at the primary stakeholders who are both the drivers and recipients of these specific set of sustainability initiatives. In order to obtain results to these questions, I examined the sustainability reports of the five aforementioned companies for years 2008 and 2014 from the GOLDEN Project database. I used qualitative content analysis as my method to establish which initiatives and stakeholders were…
Human Rights in Tourism: Conceptualization and Stakeholder Perspectives
2007
The present paper is an attempt to integrate the concept of human rights into the mainstream tourism discourse. In the name of development, human rights are often neglected while there are definite long-term advantages to be gained by actively promoting it. The paper examines the human rights perspectives of the major stakeholder groups in tourism to finally arrive at a comprehensive picture. Implications of some of the general principles and proclaimed guidelines of human rights for tourism are discussed. It is concluded that sustainable development of tourism is not possible until human rights as a relevant category is recognized by all the stakeholders. In addition, a case study is provi…
Computer mediated organizational memory for process control : moving CSCW research from an idea to a product
2002
This study provides a rare examination of the development process of collaborative applications from a research idea into a commercially introduced software. The research challenge here is to investigate how to enhance the communication and information sharing in process control environments with computerized tools. Such environments can be characterized by time-criticality, complexity and turbulence. The study deploys the technological, human, and business approaches into a research driven system design. It draws upon experiences of a more than six-year longitudinal and constructive research project focusing on the design, adoption and tailoring of computer support (organizational memory) …
Cognitive Mimetics and Human Digital Twins : Towards Holistic AI Design
2023
AI is replacing and supporting people in many intelligence-requiring tasks. Therefore, it is essential to consider the conceptual grounds of designing future technical artefacts and technologies for practical use. We are developing two new practical design tools: cognitive mimetics and human digital twins for AI designers. Cognitive mimetics analyses human information processing to be mimicked by intelligent technologies. Human digital twins provide a tool for modelling what people do based on the results of cognitive mimetics. Together they provide a new way of designing intelligent technology in individual tasks and industrial contexts. nonPeerReviewed
Characteristics of Finnish medical and engineering research group work
2004
Tutkimusryhmätyöskentelyä lääketieteissä ja teknisissä tieteissä tutkinut Jani Ursin toteaa väitöskirjansa olevan puheenvuoro tutkimusryhmien puolesta. Ursin kuvailee tutkimilleen tutkimusryhmille tyypillisiksi piirteiksi sisäisen harmonisuuden, mutta akateemisten piirteiden vähäisyyden sekä tieteenalaan sidoksissa olevien käytänteiden ja normien näkymättömyyden ryhmätyöskentelyssä. The study examined research group work characteristics from the perspective of the work design approach. The purpose was, first, to describe research group work characteristics and, second, to explore the relationships between different work characteristics and form a model with which to analyse research group w…
Dog-Owner Relationship, Owner Interpretations and Dog Personality Are Connected with the Emotional Reactivity of Dogs
2022
Simple Summary The relationship between owner and the dog affects the dog's attachment behaviors and stress coping. In turn, the quality of the relationship may affect owner's interpretations about their dog's behavior. Here, we assessed dogs' emotional responses from heart rate variability and behavioral changes during five different situations. Dog owners evaluated the emotion (valence and arousal) of their dog after each situation. We found that both negative and positive incidents provoked signs of emotional arousal in dogs. Owners detected the dog's arousal especially during fear- and stress-evoking situations. The dog-owner relationship did not affect owners' interpretation of dogs' e…
Physiological and autonomic stress responses after prolonged sleep restriction and subsequent recovery sleep in healthy young men
2018
Purpose Sleep restriction is increasingly common and associated with the development of health problems. We investigated how the neuroendocrine stress systems respond to prolonged sleep restriction and subsequent recovery sleep in healthy young men. Methods After two baseline (BL) nights of 8 h time in bed (TIB), TIB was restricted to 4 h per night for five nights (sleep restriction, SR, n = 15), followed by three recovery nights (REC) of 8 h TIB, representing a busy workweek and a recovery weekend. The control group (n = 8) had 8 h TIB throughout the experiment. A variety of autonomic cardiovascular parameters, together with salivary neuropeptide Y (NPY) and cortisol levels, were assessed.…
Phase retrieval of vitreous floaters: simulation experiment
2020
Knowledge of the structure of vitreous floaters is crucial to evaluate the need for surgical removal of these floaters. We simulated the phase retrieval of microstructures simulating vitreous floaters by an algorithm PhaseLift and investigate the effects of various parameters on the retrieved phase. The object under test was modulated and the coded diffraction patterns were calculated. Next, PhaseLift was used to retrieve the phase. In the current study, we simulate the effect of Gaussian and Poison noise on the phase retrieval of pure phase objects. We apply an iterative algorithm PhaseLift for phase retrieval as this algorithm requires a very few modulating masks and is able to retrieve t…
A Domain Imbedding Method with Distributed Lagrange Multipliers for Acoustic Scattering Problems
2003
The numerical computation of acoustic scattering by bounded twodimensional obstacles is considered. A domain imbedding method with Lagrange multipliers is introduced for the solution of the Helmholtz equation with a second-order absorbing boundary condition. Distributed Lagrange multipliers are used to enforce the Dirichlet boundary condition on the scatterer. The saddle-point problem arising from the conforming finite element discretization is iteratively solved by the GMRES method with a block triangular preconditioner. Numerical experiments are performed with a disc and a semi-open cavity as scatterers.
Optimisation algorithms in the case of mineral detection using Raman Analysis
2013
Abstract Raman analysis can be used to analyse the existence of minerals in an ore sample. Especially the interest here is to analyse given ore sample rapidly, to find out what minerals it contains. Rapid analysis would enable more rapid exploration of minerals as analysis could be carried out on-site. For this study, ore samples were collected from two mines in Northern Finland, Kittila and Kevitsa. An optimisation algorithm was constructed to form a linear combination of reference spectra which best represent the measured spectrum from an ore sample. The reference spectra were collected from a public source. It was found that solving for an optimal summation of reference spectra can be a …
