Yritysvastuuraportoinnin vertailukelpoisuus ja raportoinnin kehittäminen : case KONE Oyj
2013
Tämän tutkimuksen tarkoitus oli selvittää vastuuraportoinnin vertailtavuutta parantavia tekijöitä ja miten vertailukelpoisuutta voidaan kehittää yrityksissä. Tutkimuksen kohdeyrityksenä on KONE Oyj, jonka vastuuraportoinnin parantamiseksi annettiin kehitysehdotuksia. Tutkimuksen metodologinen lähestymistapa on kvalitatiivinen case-tutkimus. Tutkimus toteutettiin kahdella metodilla: Ensimmäinen osa sisältää vastuuraporttien vertailututkimuksen, jossa vertailtiin KONEen, ThyssenKruppin, Metson ja Ahlstromin vastuuraportteja raportoinnin selittävien teorioiden, GRI:n sisältö- ja laatutekijöiden, sertifiointien ja standardien, sisällön jatkuvuuden ja lukujen esittämisen sekä ulkoisen varmennuks…
Robust Light Field Watermarking by 4D Wavelet Transform
2020
Unlike common 2D images, the light field representation of a scene delivers spatial and angular description which is of paramount importance for 3D reconstruction. Despite the numerous methods proposed for 2D image watermarking, such methods do not address the angular information of the light field. Hence the exploitation of such methods may cause severe destruction of the angular information. In this paper, we propose a novel method for light field watermarking with extensive consideration of the spatial and angular information. Considering the 4D innate of the light field, the proposed method incorporates 4D wavelet for the purpose of watermarking and converts the heavily-correlated chann…
HyperLabelMe : A Web Platform for Benchmarking Remote-Sensing Image Classifiers
2017
HyperLabelMe is a web platform that allows the automatic benchmarking of remote-sensing image classifiers. To demonstrate this platform's attributes, we collected and harmonized a large data set of labeled multispectral and hyperspectral images with different numbers of classes, dimensionality, noise sources, and levels. The registered user can download training data pairs (spectra and land cover/use labels) and submit the predictions for unseen testing spectra. The system then evaluates the accuracy and robustness of the classifier, and it reports different scores as well as a ranked list of the best methods and users. The system is modular, scalable, and ever-growing in data sets and clas…
Towards the integration and development of a cross-European research network and infrastructure: the DEterminants of DIet and Physical ACtivity (DEDI…
2014
To address major societal challenges and enhance cooperation in research across Europe, the European Commission has initiated and facilitated ‘joint programming’. Joint programming is a process by which Member States engage in defining, developing and implementing a common strategic research agenda, based on a shared vision of how to address major societal challenges that no Member State is capable of resolving independently. Setting up a Joint Programming Initiative (JPI) should also contribute to avoiding unnecessary overlap and repetition of research, and enable and enhance the development and use of standardised research methods, procedures and data management. The Determinants of Diet …
Searching the Web for conflicting topics: Page and user factors
2013
Web users tend to search only the pages displayed at the top of the search engine results page (the 'top link' heuristic). Although it might be reasonable to use this heuristic to navigate simple and unambiguous facts, it might be risky when searching for conflicting socio-scientific topics, such as potential measures to reduce greenhouse gas emissions. In the present study, we explored the extent to which students consider other Web page characteristics, such as topic relevance and trustworthiness, when searching and bookmarking pages concerning a conflicting topic. We also examined the extent to which prior background knowledge moderates students' behavior. The results revealed that while…
Benchmarking open data efforts through indices and rankings: Assessing development and contexts of use
2022
Abstract This paper aims to provide a broad perspective on the development of benchmarking open data efforts through indices and rankings over the years, both at the level of countries and allowing for a cross-country comparison. The methodology follows a systematic search for the relevant resources, their classification and identification of six open data benchmarks to be further analyzed, the identification of their key components through decomposition, their description, and identifying the similarities and differences. Three major groups of indices and four periods that characterize the efforts to benchmark and measure the development of open data are identified, where the first measure…
Benchmarking Wilms’ tumor in multisequence MRI data: why does current clinical practice fail? Which popular segmentation algorithms perform well?
2019
Wilms' tumor is one of the most frequent malignant solid tumors in childhood. Accurate segmentation of tumor tissue is a key step during therapy and treatment planning. Since it is difficult to obtain a comprehensive set of tumor data of children, there is no benchmark so far allowing evaluation of the quality of human or computer-based segmentations. The contributions in our paper are threefold: (i) we present the first heterogeneous Wilms' tumor benchmark data set. It contains multisequence MRI data sets before and after chemotherapy, along with ground truth annotation, approximated based on the consensus of five human experts. (ii) We analyze human expert annotations and interrater varia…
The impact of privatization approaches on the productivity growth of the water industry: A case study of Chile
2015
Abstract The water industry faces the challenge of implementing privatization reforms. This process mainly adopts the following two approaches: the privatization of public water and sewerage services (WSS) and the privatization of water companies’ ownership. This paper investigates the impact of both privatization approaches on changes in productivity in the water industry. In doing so, the Luenberger productivity indicator (LPI) was computed for a sample of Chilean water and sewerage companies (WaSCs) for the period 1997–2013. Unlike the most commonly applied index (Malmquist productivity index), the LPI simultaneously takes into account output expansion and input contraction. The results …
Barriers in organizing the Romanian firms in responsibility centers
2017
In the current turbulent business environment, the big and medium enterprises must organize their activity in order to face new challenges. One of the organizational forms that can stimulate the performances of the firms is the one in responsibility centers. This paper addresses the issue of the responsibility centers starting from the possibility of using benchmarking before and after the implementation of this organizational form. After highlighting the advantages of the responsibility centers, we presented a study made in Romanian big and medium organizations, regarding the barriers in the design and implementation of this organizational form. The main causes that determine Romanian mana…
Physical environment as a source for innovation: investigating the attributes of innovative space
2013
Purpose – The purpose of this paper is to investigate how physical spaces intersect with innovation and innovativeness, and what the most relevant attributes of physical space are for innovation. Design/methodology/approach – The paper reflects the changing nature of innovation, from technological advancements to services and meaning changes, and argues that the development of innovative spaces similarly embodies a diverse set of values such as collaboration, openness, and sustainability. Using a literature review, interviews, and benchmarking data, the paper examines the relationship between physical environment and innovation. Findings – The findings from both the literature review and t…
