Joining the Debate: Creativity Seen from Eastern and Central Europe
Vlad Petre Glăveanu,Maciej Karwowski 대한사고개발학회 2013 The International Journal of Creativity & Problem Vol.23 No.1
This special issue, as seen from above, covers at least three important themes and showcases research from a series of different Eastern and Central European countries using a variety of methodologies, from surveys to psychobiography. It stands as a testimony for the growing interest in creativity in this part of the world and also for the valuable insights creativity research worldwide can take when focusing on this geo-cultural location. Studies of implicit theories and creativity enhancement programmes are not unique only to this context, however, the ways in which the authors approach them and the widespread concern for social and cultural variables sets these investigations apart at least from more mainstream, ‘Western’ psychology. A focus on culture is not gratuitous as many scholars today realise (Lubart, 1999; Simonton, 2003) and it is perhaps here where Eastern researchers have the greatest contribution to make. This is because Eastern and Central Europe is not only a place with a rich and diverse cultural heritage but also a space in which people understand the importance of living within a society and a culture and trying to preserve and transform them, ‘from within’, in ways that both reflect and support creative expression. Preparation of this special issue was possible thanks to the warm reaction of James C. Kaufman and the whole editorial board. We would like to express our gratitude to all editorial board members who served as peer reviewers during the submission and review process as well as to several ad hoc reviewers who helped us and the authors improve their articles. The full list of reviewers is attached at the end of this issue. Finally we would like to thank the authors who responded to our call and invite readers to engage with these contributions and discover creativity as it is seen from Eastern and Central Europe.

This paper builds on a recent method, chain routing with even energy consumption (CREEC), for designing a wireless sensor network with chain topology and for scheduling the communication to ensure even average energy consumption in the network. In here a new suboptimal design is proposed and compared with the CREEC design. The chain topology in CREEC is reconfigured after each group of n converge-casts with the goal of making the energy consumption along the new paths between the nodes in the chain as even as possible. The new method described in this paper designs a single near-optimal Hamiltonian circuit, used to obtain multiple chains having only the terminal nodes different at different converge-casts. The advantage of the new scheme is that for the whole life of the networkmost of the communication takes place between same pairs of nodes, therefore keeping topology reconfigurations at a minimum. The optimal scheduling of the communication between the network and base station in order to maximize network lifetime, given the chosen minimum length circuit, becomes a simple linear programming problem which needs to be solved only once, at the initialization stage. The maximum lifetime obtained when using any combination of chains is shown to be upper bounded by the solution of a suitable linear programming problem. The upper bounds show that the proposed method provides near-optimal solutions for several wireless sensor network parameter sets.
Is the Lightbulb Still ON? Social Representations of Creativity in a Western Context
Vlad Petre Glaveanu 대한사고개발학회 2011 The International Journal of Creativity & Problem Vol.21 No.1
The present article aims to explore the social representations of creativity in a Western cultural context. In doing so it starts by addressing the theoretical bases for such an investigation and especially the more developed literature on implicit theories of creativity. Contributions of the social representations approach are discussed, in particular the mechanisms of anchoring and objectification and processes of thematisation. The empirical research was based on an on-line survey and the analysis included 106 responses, mainly from participants living in the US and the UK. The questionnaire employed both closed and open-ended questions concerning: a) common creativity symbols; b) existing dichotomies about the nature of creativity, and c) self-evaluations of creativity. Participants were first asked to think of what would be the best creativity symbol for them and to rate and comment on eight symbols emerging out of a pre-study of Google Images. Findings indicate that current representations of creativity are complex and multifaceted and the strongest association present was between creativity and the arts (especially symbols like paintbrush and colour, children’s drawings, etc.). This has several important practical implications for how creativity is understood, recognised and legitimated in everyday contexts.
Scalar Dissipation Rate Characteristics in Steady and Unsteady Turbulent Round Jets
Vlad Aparece-Scutariu,Edward S Richardson,Dong-hyuk Shin(신동혁) 한국연소학회 2019 KOSCOSYMPOSIUM논문집 Vol.2019 No.11
The scalar dissipation rate (SDR) quantifies the mixing-rate between a turbulent jet and ambient fluids and is essential for modeling turbulent non-reacting/reacting flows. This study investigates SDR characteristics using Direct Numerical Simulation (DNS). For the steadystate jet, radial profiles of ensemble-averaged SDRs exhibit self-similar behaviours. The SDR is highest at the centreline, remains plateau at small radii, decreasing gradually at larger radii. The starting jet shows increased SDR values near the leading vortices, while recovering to steady-state jet values afterwards.
Uncertainties impact on the major FOMs for severe accidents in CANDU 6 nuclear power plant
R.M. Nistor-Vlad,D. Dupleac,G.L. Pavel Korean Nuclear Society 2023 Nuclear Engineering and Technology Vol.55 No.7
In the nuclear safety studies, a new trend refers to the evaluation of uncertainties as a mandatory component of best-estimate safety analysis which is a modern and technically consistent approach being known as BEPU (Best Estimate Plus Uncertainty). The major objectives of this study consist in performing a study of uncertainties/sensitivities of the major analysis results for a generic CANDU 6 Nuclear Power Plant during Station Blackout (SBO) progression to understand and characterize the sources of uncertainties and their effects on the key figure-of-merits (FOMs) predictions in severe accidents (SA). The FOMs of interest are hydrogen mass generation and event timings such as the first fuel channel failure time, beginning of the core disassembly time, core collapse time and calandria vessel failure time. The outcomes of the study, will allow an improvement of capabilities and expertise to perform uncertainty and sensitivity analysis with severe accident codes for CANDU 6 Nuclear Power Plant.
