Distributed leadership in Finnish and Shanghai schools
2016
The present research employed mixed-methods approach to further theorise distributed leadership and to investigate its manifestations in Finnish and Shanghai schools. The whole research comprised two phases. The first phase contained a meta-analysis (Sub-study I), which systematically reviewed 85 key distributed leadership articles published between 2002 and 2013. The meta-analysis identified two main research paradigms: the descriptive-analytical paradigm and the prescriptive-normative paradigm. It also yielded a resource–agency duality model of distributed leadership. In this model, distributed leadership is seen as a process with both organisational and individual perspectives. From the …
Hybrid chaotic firefly decision making model for Parkinson’s disease diagnosis
2020
Parkinson’s disease is found as a progressive neurodegenerative condition which affects motor circuit by the loss of up to 70% of dopaminergic neurons. Thus, diagnosing the early stages of incidence is of great importance. In this article, a novel chaos-based stochastic model is proposed by combining the characteristics of chaotic firefly algorithm with Kernel-based Naïve Bayes (KNB) algorithm for diagnosis of Parkinson’s disease at an early stage. The efficiency of the model is tested on a voice measurement dataset that is collected from “UC Irvine Machine Learning Repository.” The dynamics of chaos optimization algorithm will enhance the firefly algorithm by introducing six types of chao…
Hydraulic vs. Electric: A Review of Actuation Systems in Offshore Drilling Equipment
2016
This article presents a survey on actuation systems encountered in offshore drilling applications. Specifically, it focuses on giving a comparison of hydraulic and electric drivetrains along with detailed explanations of their advantages and drawbacks. A significant number of industrial case studies is examined in addition to the collection of academic publications, in order to accurately describe the current market situation. Some key directions of research and development required to satisfy increasing demands on powertrains operating offshore are identified. The impact of the literature and application surveys is further strengthened by benchmarking two designs of a full-scale pipe handl…
A Feature Rich Distance-Based Many-Objective Visualisable Test Problem Generator
2019
In optimiser analysis and design it is informative to visualise how a search point/population moves through the design space over time. Visualisable distance-based many-objective optimisation problems have been developed whose design space is in two-dimensions with arbitrarily many objective dimensions. Previous work has shown how disconnected Pareto sets may be formed, how problems can be projected to and from arbitrarily many design dimensions, and how dominance resistant regions of design space may be defined. Most recently, a test suite has been proposed using distances to lines rather than points. However, active use of visualisable problems has been limited. This may be because the ty…
Redesigning Computer-Supported Work Processes with Dual Information Systems: The Work Process Benchmarking Service
1999
The conceptual design of most computer-based information systems reflects a dualism of technology. During the development phase, part of the work-domain-related knowledge is formalized and encoded in the software, making it difficult for users to reflect on and use this knowledge. This design/use dualism contributes to the deterioration of the interpretive flexibility of information systems. We propose an information systems architecture called Dual Information Systems (DIS) that helps bridge the design/use dualism by providing organizations with a set of services that enable and reinforce both effective, institutionalized working and the questioning and (re)construction of computer-support…

Fundusz Medyczny - organizacja i zasady gospodarki finansowej
2021
Celem artykułu jest analiza przepisów normujących organizację i zasady gospodarki finansowej Funduszu Medycznego w kontekście funkcji, jakie w doktrynie prawa finansowego przypisuje się funduszom celowym. W pierwszej części opracowania poddano ocenie regulacje dotyczące organizacji i zadań tej jednostki. Drugą poświęcono przedstawieniu źródeł finansowania oraz zasad gospodarki finansowej Funduszu, zwracając szczególną uwagę na problem zasilania tej jednostki tzw. wpłatą z budżetu państwa. Z uwagi na ograniczone ramy artykułu do odrębnego opracowania pozostawiono problematykę programów inwestycyjnych oraz kwestię trybu i zasad przekazywania środków z Funduszu. Stosując metody właściwe współc…
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…
THE ENTERIC NERVOUS SYSTEM: NEW DEVELOPMENTS AND EMERGING CONCEPTS
2011
The enteric nervous system (ENS) is an integrative neuronal network, organized in two ganglionated plexuses, myenteric and submucosal, composed of neurons and enteric glial cells, controlling the activity of the smooth muscle of the gut, mucosal secretion and blood flow. The ENS contains as many neurons as the spinal cord, and the functional and chemical diversity of enteric neurons closely resembles that of the central nervous system. This highly integrated neural system is also referred to as the ‘brain-in-the-gut’, because of its capability to function in the absence of nerve inputs from the central nervous system.
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…
