Identification of international media events by spatial and temporal aggregation of RSS flows of newspapers
2013
The GEOMEDIA research project (ANR Corpus, 2013-2015) aims to elaborate an international observatory of media events, based on the collection of RSS flows sent by 100 newspapers of French and English languages. This contribution (1) describes the complexity of the information contained in RSS flows according to space, time and media dimensions; (2) derives basic solutions for the identification of international events on the basis of procedures of time aggregation; (3) analyzes the spatial interaction between countries through an analysis of co-quotations in RSS flows; (4) checks the existence of possible interactions between the two previous dimensions.
A distributed leadership perspective on the Finnish curriculum reform 2014
2018
Bridging curriculum research with educational leadership, we examined the 2014 Finnish curriculum reform compilation and enactment process through the lens of distributed leadership.As a tool for t...
Distributed leadership and teacher’ self-efficacy : the case studies of three Chinese schools in Shanghai
2011
This study looks into the distributed leadership and its influence on teachers’ self-efficacy in three Chinese schools in Shanghai. Against the background of the eighth national curriculum reform launched in 2002, the Chinese schools are seeking for the new way to enhance the school-based curriculum. On top of that, the trend of decentralization also encourages the school principals to involve the teachers in the school leadership practice. The relationship between distributed leadership and teachers’ self-efficacy in this study is examined from the angle of principals’ empowerment strategies. A mixed methods approach is applied to collect both qualitative and quantitative data from the thr…
Elements of Sustainability for Public Sector Software : Mosaic Enterprise Architecture, Macroservices, and Low-Code
2021
Public sector is a large consumer for software. In countries such as Finland, many of the systems are made to order by consultancy companies that participate in public tenders. These tenders initiated by the state, cities, and other public sector organizations. Furthermore, as public sector tasks are often decomposed to various actors, each and every one of them makes their purchase based on their own needs. In this paper, we argue that to maintain software sustainability in this context, there is a need for three key elements. Firstly, there is a need for an enterprise architecture where independent services from various vendors are can be easily deployed and integrated. Secondly, these se…
Success factors in distributed agile development : case study
2018
This thesis aimed to figure out success factors in distributed software development conducting literature review and empirical research. The motivation for this research rose from practical work experience and the notion that usage of agile development has increased same time as global distributed software development has become more common. The research question formed to investigate the topic was: “What are success factors in distributed agile development and what experiences about this combination already exists?” To answer research question, there were conducted literature review of existing literature and empirical case study research executed using theme interviews. In literature revi…
Accounting for soil parameter uncertainty in a physically based and distributed approach for rainfall-triggered landslides
2016
In this study we propose a probabilistic approach for coupled distributed hydrological-hillslope stability models that accounts for soil parameters uncertainty at basin scale. The geotechnical and soil retention curve parameters are treated as random variables across the basin and theoretical probability distributions of the Factor of Safety (FS) are estimated. The derived distributions are used to obtain the spatio-temporal dynamics of probability of failure, in terms of parameters uncertainty, conditioned to soil moisture dynamics. The framework has been implemented in the tRIBS-VEGGIE (Triangulated Irregular Network (TIN)-based Real-time Integrated Basin Simulator-VEGetation Generator fo…
Groupware architecture for requirements processes in new product development
1999
An organization's ability to create successful products depends on how extensively it collects, analyzes and utilizes requirements information in its product development. Recent advances in groupware technologies allow such information to be shared more effectively in distributed organizations; thus, these technologies hold considerable potential as means of shortening the cycle time and improving the quality of requirements processes. This paper addresses issues in the design and implementation of groupware-supported requirements processes by drawing on experiences from large-scale industrial development projects within Nokia. The primary contribution of the paper is the conceptual design …
Estimation of synthetic flood design hydrographs using a distributed rainfall–runoff model coupled with a copula-based single storm rainfall generator
2014
Abstract. In this paper a procedure to derive synthetic flood design hydrographs (SFDH) using a bivariate representation of rainfall forcing (rainfall duration and intensity) via copulas, which describes and models the correlation between two variables independently of the marginal laws involved, coupled with a distributed rainfall–runoff model, is presented. Rainfall–runoff modelling (R–R modelling) for estimating the hydrological response at the outlet of a catchment was performed by using a conceptual fully distributed procedure based on the Soil Conservation Service – Curve Number method as an excess rainfall model and on a distributed unit hydrograph with climatic dependencies for the …
Distributed Leadership and the Visibility/Invisibility Paradox in On-line Communities
2011
This paper analyzes the role of distributed leadership in three on-line communities, reflecting on an observed visibility/invisibility paradox in leadership within these communities. Leaders who downplay their seniority and assume a degree of invisibility, allocating discretionary powers to subordinate levels in an organizational hierarchy, may facilitate the emergence of distributed leadership. Yet, simultaneously, leader-led relations are enabled by high leadership visibility. This paradox—that leaders need to be both highly visible and also invisible, or hands-off, when the occasion requires it—was derived from prior research into e-learning communities and tested in the analysis of disc…
Distributing leadership in a day care setting
2016
The latest leadership theories require leadership to be distributed, but there is little evidence of how the distribution is made in practice, particularly in the context of early childhood education. This article describes leadership in two day care organizations in which the organizational structure was different than the traditional one. One organization comprised four day care units and the other had five units. According to the findings, leadership was implemented in the spirit of distributed leadership. The staff and the day care centre director in co-operation took responsibility for their organization. The relationship between the director and the staff was interactive and there was…
