A relevance feedback CBIR algorithm based on fuzzy sets
2008
CBIR (content-based image retrieval) systems attempt to allow users to perform searches in large picture repositories. In most existing CBIR systems, images are represented by vectors of low level features. Searches in these systems are usually based on distance measurements defined in terms of weighted combinations of the low level features. This paper presents a novel approach to combining features when using multi-image queries consisting of positive and negative selections. A fuzzy set is defined so that the degree of membership of each image in the repository to this fuzzy set is related to the user's interest in that image. Positive and negative selections are then used to determine t…
Conclusion: A Conversation
2017
In the concluding chapter the editors of the volume take a conversational look into the producing process of Nordic Girlhoods: New Perspectives and Outlooks. The authors discuss key contemporary issues and future perspectives in Nordic girlhood studies and foreground the political relevance of the research field in the contemporary societal situation. They call for reflexive and critical theorizations on what counts as the Nordic, especially when the girl is to be found in the middle of several nationalistic desires and conservative political discourses.
Conceptualizing Online Discussion Value: A Multidimensional Framework for Analyzing User Comments on Mass-Media Websites
2013
This chapter provides a micro-framework for analyzing the quantity and quality of online user comments on mass-media websites. On one dimension, news factors of news items and discussion factors of existing user comments are assumed to indicate the relevance of participating in online discussions. On a second dimension, specific motivational, social, and design factors are influential when reconstructing users’ decisions to participate in online discussions and when analyzing the content of online user comments. The two dimensions in combination describe the discussion value of news items. Potential applications of this framework on other forms of interpersonal communication are discussed.
Zarządcze aspekty logistyki jako determinanty rozwoju potencjałów strategicznych przedsiębiorstwa
2019
Przedsiębiorstwa stale poszukują sposobów tworzenia przewagi konkurencyjnej. W procesie budowania tej przewagi istotne znaczenie mają potencjały strategiczne przedsiębiorstwa, obejmujące przede wszystkim zasoby, zdolności oraz kompetencje. W rozwoju tych potencjałów ważną rolę odgrywa logistyka. Celem artykułu jest identyfikacja zarządczych aspektów logistyki oraz przesłanek ich oddziaływania na rozwój potencjałów strategicznych przedsiębiorstwa.
 Artykuł ma charakter koncepcyjny. Na początku przedstawiono pokrótce istotę logistyki jako koncepcji zarządzania przepływami towarów i informacji oraz najważniejsze fazy w jej rozwoju. Następnie zaprezentowano istotę i znaczenie potencjał…
Global Functional Analyses of Cellular Responses to Pore-Forming Toxins
2011
Here we present the first global functional analysis of cellular responses to pore-forming toxins (PFTs). PFTs are uniquely important bacterial virulence factors, comprising the single largest class of bacterial protein toxins and being important for the pathogenesis in humans of many Gram positive and Gram negative bacteria. Their mode of action is deceptively simple, poking holes in the plasma membrane of cells. The scattered studies to date of PFT-host cell interactions indicate a handful of genes are involved in cellular defenses to PFTs. How many genes are involved in cellular defenses against PFTs and how cellular defenses are coordinated are unknown. To address these questions, we pe…
Emerging and Traditional Donors in the ‘Post-Busan’ Context: Assessing Brazil’s and Finland’s Cooperation Practices in Mozambique
2015
At the same time as the ‘emerging donors’ have gained relevance in the development cooperation system, they have also challenged established principles of aid. This article compares Brazil's and Finland's development cooperation practices in the light of recent global tendencies in the aid architecture. Based on empirical research carried out in Mozambique, Brazil, and Finland, the article gives a detailed review of the institutional and historical settings of each bilateral cooperation. The authors then analyse how two central concepts reinforced during the Busan High Level Forum have been put into practice by a ‘new emerging’ and a ‘traditional Nordic’ donor. For ‘development effectivenes…
Effectively and efficiently supporting crowd-enabled databases via NoSQL paradigms
2013
In this paper we provide an overview of the Hints From the Crowd (HFC) project, whose main goal is to build a NoSQL database system for large collections of product reviews; the database is queried by expressing a natural language sentence; the result is a list of products ranked based on the relevance of reviews w.r.t. the natural language sentence. The best ranked products in the result list can be seen as the best hints for the user based on crowd opinions (the reviews). The HFC prototype has been developed as a web application, independent of the particular application domain of the collected product reviews. Queries are performed by evaluating a text-based ranking metric for sets of re…
Gudommelig gymnastikk – kroppslighetens plass i Rudolf Steiners pedagogiske tenkning
2019
ABSTRACT English title: Divine Gymnastics - The Significance of the Body in Rudolf Steiner's Pedagogy This article discusses how Rudolf Steiner’s belief in the importance of the body and movement inschool comes across in his book Oppdragelse og tidens andliv (1986) a collection of public lecturesheld in 1923 in Ilkley, England. I will juxtapose Steiner’s descriptions of the body’s significance forchildren’s processes of bildung with other ideas of reform pedagogy. My intention is to see whetherSteiner’s appreciation of the body and movement in school can be of relevance to today’s debate oneducational policy. Steiner views bodily processes as a foundation for mental processes and arguesthat…
The Inside Information Regime of the MAR and the Rise of the ESG Era
2020
The rise in ESG investing has been characterized as an “investor revolution” and a manifestation of “social change”. The current coronavirus pandemic will arguably intensify the impact of such social change, with the “S” and “G” components of ESG, in particular, having been brought into sharper focus during the crisis. The issue of the extent to which ESG factors are (currently) of considerable importance – and, in particular, are likely to become even more so in the future – for the performance of share prices remains a highly controversial one in financial economics. However, where an empirically substantiated effect of ESG-related information on the prices of financial instruments can be…
Why and how to use enterprise social media platforms: The employee’s perspective
2021
Abstract Literature supports the relevance of knowledge sharing in a company. Considering that social media plays an important role in this process, this paper analyzes the antecedents and consequences of the use of enterprise social media platforms according to the employee's perception. Based on the Motivation-Opportunity-Ability framework and using two different methodologies (Partial Least Squares Structural Equation Modeling and fuzzy-set Qualitative Comparative Analysis), we find that three different combinations of motivation, opportunity and ability factors, combined in pairs, promote the use of enterprise social media platforms, leading to knowledge creation and task performance. T…
