What do we do when we analyse the temporal aspects of computer-supported collaborative learning? A systematic literature review
2021
To better understand the premises for successful computer-supported collaborative learning (CSCL), several studies over the last 10 years have analysed the temporal aspects of CSCL. We broadly define the temporal aspects of CSCL as focusing on the characteristics of or interrelations between events over time. The analysis of these aspects, however, has been loosely defined, creating challenges regarding the comparability and commensurability of studies. To address these challenges, we conducted a systematic literature review to define the temporal analysis procedure for CSCL using 78 journal papers published from 2003 to 2019. After identifying the key operations to be included in the proce…
Nomadtown, Manifesting the Global Village Hypothesis: A Case Study of a Rural Resilience Hub Within an Educational Milieu in North Karelia, Finland
2022
Artikkelissa esitellään NomadTown, joka on hätätilojen ennakointiin, torjuntaan ja sopeutumiseen sekä myönteisten vaikutusten tuottamiseen toimintansa perustava “resilienssihubi”. Artikkelissa hahmotellaan NomadTowniin kehittyneen alakulttuurin koulutuksellista taustaa ja tehdään syvällinen kuvaus NomadTownia ympäröivästä yhteiskunnasta oppimisen paikkana. Tämä kontekstuaalisointi nojaa tietoisuuteen dispositiivista Foucault'n tarkoittamassa mielessä. Tekstissä arvioidaan yhdistysten yhteiskuntaekologian, jonka puitteisiin tämä resilienssikeskus on asettumassa, soveltuvuutta ilmastonmuutoksen torjunnan edellyttämään suureen yhteiskunnalliseen transitioon. Lisäksi arvioidaan kuinka verkostom…
Organizational Learning from Cybersecurity Performance: Effects on Cybersecurity Investment Decisions
2023
AbstractIS literature has identified various economic, performance, and environmental factors affecting cybersecurity investment decisions. However, economic modeling approaches dominate, and research on cybersecurity performance as an antecedent to investments has taken a backseat. Neglecting the role of performance indicators ignores real-world concerns driving actual cybersecurity investment decision-making. We investigate two critical aspects of cybersecurity performance: breach costs and breach identification source, as antecedents to cybersecurity investment decisions. We use organizational learning to theorize how performance feedback from these two aspects of cybersecurity breaches …
Critical issues and future prospects of the secondary substation in smart grid context
2014
This paper is focused on the new role of the secondary substation in the smart grids context. This innovative view has been proposed and developed in the framework of two Research Projects: NewCabELARC Project and Reipersei Project. The latter provides a concrete and comprehensive low cost solutions for the smart grid monitoring and control, allowing the real diffusion and integration of Distributed Generation and the full exploitation of Renewable Energy Sources. In this field, this paper shows how the secondary substation (SS) takes the role of smart transducer node where innovative devices can be located, collecting the measurement data coming from the field devices (power and energy met…
The relevance of point defects in studying silica-based materials from bulk to nanosystems
2019
The macroscopic properties of silica can be modified by the presence of local microscopic modifications at the scale of the basic molecular units (point defects). Such defects can be generated during the production of glass, devices, or by the environments where the latter have to operate, impacting on the devices’ performance. For these reasons, the identification of defects, their generation processes, and the knowledge of their electrical and optical features are relevant for microelectronics and optoelectronics. The aim of this manuscript is to report some examples of how defects can be generated, how they can impact device performance, and how a defect species or a physical phenomenon …
Water distribution network robust design based on energy surplus index maximization
2015
The aim of this paper is to show that energy surplus indices, such as resilience index, besides providing a very good indirect measure of water distribution network reliability to be adopted during the design phase, represent also a valuable and effective indicator of the robustness of the network in alternative network scenarios, and can thus be profitably used in condition of future demands uncertainty. The methodology adopted consisted of (I) multi-objective design optimization performed in order to minimize construction costs while maximizing the resilience index; (II) retrospective performance assessment of the alternative solutions of the Pareto front obtained, under demand conditions…
Expectations and Experiences of Implementing a Mobile Secure Communication Application
2020
The privacy and security of communication in corporations and governmental organizations has increased enormously over the years. At the same time, a growing amount of technological solutions to support this have emerged. This study examines user expectations before and use experiences during the implementation phase of a mobile secure communication application. These are investigated from the expectation–confirmation perspective and its influence on continued adoption. The study has an exploratory approach for this investigation. To guide the investigation, the study draws from the expectation–confirmation theory (ECT) and the unified theory of acceptance and use of technology (UTAUT). Emp…
Setting the agenda for research on issue arenas
2014
Purpose– This paper seeks to contribute to the field of corporate communication by clarifying the theoretical basis of communication in issue arenas and proposing an agenda for research on issue arenas.Design/methodology/approach– Drawing on insights from stakeholder thinking, network theory, issues management, and agenda-setting theory, the authors identify different levels of analysis that could explain the behaviour of organisations in the public debate on current issues.Findings– The organisation-centred approach is replaced by a strong emphasis on interaction in networks of organisations, groups and individuals. Decision-making on communication strategies can be further developed by an…
Resilience Planning, a Facilitated Modelling Approach
2018
Resilience has emerged as a buzzword among researchers and practitioners. However, despite its popularity, there has been little progress in moving it from an elaborate metaphor describing an idyllic state of the system to a tool for planning and managing adaptation. While case study research is rich with examples of systems that have proven to be resilient or are striving to develop resilience, there is no defined approach that operationalises concepts described in the literature into the planning process. This paper helps close this gap by illustrating how facilitated modelling can be used for resilience planning in socio-ecological systems. The paper summarizes our experience using facil…
Franczyzobiorca: między konsumentem a przedsiębiorcą. Mity o regulacji franczyzy
2022
Niniejsze opracowanie odnosi się do zagadnienia dyskusji nad uregulowaniem franczyzy w Polsce. W skazano w nim na potencjalne obszary regulacji, jak również, że kluczowe znaczenie ma uregulowanie obowiązków przedkontraktowych organizatora sieci franczyzowej. Obecnie kandydat na franczyzobiorcę - jako konsument - powinien korzystać z minimum ochrony konsumenckiej. Dalej odniesiono się do praw i obowiązków stron umowy, uregulowania deliktów nieuczciwej konkurencji. Osobno został przedstawiony pomysł wprowadzenia reżimu zakazu praktyk naruszających zbiorowe interesy franczyzobiorców
