An evolutionary model of voting
2001
Collective allocation of resources that takes place in po- litical markets is characterized by the complex exchange that emerges among the individuals involved. Traditional Public Choice models de- part from individual rational choice in a setup in which many of its strict requirements need not hold. This paper introduces a model of social interaction among agents in a simple political market which de- parts from bounded rationality and evolutionary dynamics as the key mechanisms that drive individual behavior. Learning plays a signicant role as it allows to establish an individual link between decisions and collective outcomes. The model is that of a representative democracy with two parti…
Realizing dynamic capabilities and organizational knowledge in effective innovations: the capabilities typological map
2022
Purpose This paper aims to shed light on the mechanisms that connect dynamic capabilities and organizational knowledge in the innovative process to offer a new theoretical and practical solution considering the microfoundations of knowledge management strategies. Design/methodology/approach This research has emerged from an in-depth case study of an effective innovation (from just ethanol and sugar-production to an effective biomass plant). The study represents an “inductive inquiry,” useful to understand specific “organizational mechanisms” of innovation, where the main data came from in-depth interviews with 18 key actors. It proved to help search the development of a specific biomass pl…
Revisiting the role of top-down and bottom-up controls in stabilisation of nutrient-rich plankton communities
2019
Understanding the conditions for successful control of phytoplankton by zooplankton in eutrophic ecosystems is a highly important research area with a wide implementation of mathematical modelling. Theoretical models generally predict destabilisation of food webs in eutrophic environments with large-amplitude oscillations of population densities which would eventually result in species extinction. On the other hand, these theoretical predic- tions are often at odds with ecological observations demonstrating stable dynamics even for a high nutrient load. This apparent discrepancy is known in the literature as Rosen- zweig’s “paradox of enrichment”. Recent theoretical works emphasize a crucia…
Argentina’s Economic Development and Life Satisfaction Revisited – 1984–2012
2014
At the end of 1983, Argentina returned to democracy. Between 1983 and 2012, Argentina brought better economic and development results as wells as an improvement in the levels of happiness and life satisfaction. Although the macroeconomic cycle was characterized by high volatility, the country GDP per capita was 74 % higher in 2012 compared to 1983, implying an average annual growth rate of 1.9 %, much higher than the average Latin American country. Poverty and income distribution as well as health and education ones notably improved after time intervals of decadence.
New paradigm of ICT productivity – Increasing role of un-captured GDP and growing anger of consumers
2015
Abstract The dramatic advancement of the Internet has led all nations to an information communication technology (ICT) driven development trajectory. This trajectory has resulted in bi-polarization between ICT growing economies and ICT advanced economies. While the former enjoys a virtuous cycle between ICT advancement and productivity increase, the later has fallen into a trap of a vicious cycle between ICT advancement and productivity decrease. This paper identifies that this trap can be attributed to the two-faced nature of ICT in which advancement of ICT contributes to price increases due to functionality development while dramatic advancement of the Internet has resulted in price decre…
The Simpson paradox of school grading in Italy
2009
Abstract Data from the 2003 OECD-PISA Survey for Italy reveal a striking difference in the relationship between students’ competence (as measured by PISA score in Mathematics) and school grades across regions: a competence level granting bare sufficiency in the North yields excellence grades in the South. This has spurred a lively debate on education policy in the country, based on the inference drawn from this evidence that grading practices are excessively different in the two areas. We show in this note that this inference overlooks a Simpson paradox hidden in the data. After a more careful analysis, the above inference is seen to be wrong. The crucial omitted variable is the school-leve…
The Influence of All-Night Exposure to Pulsed Radiofrequency Electromagnetic Fields on Human Sleep. Der Einfluss kontinuierlicher nachtlicher Exposit…
2005
Question of the study The widespread use of mobile telephones has led to public discussion about the putative health hazards as well as scientific interest in the interactions of pulsed, high-frequency electromagnetic fields with physiological systems. This article presents a survey of three consecutive studies carried out by a research group at the University of Mainz.
Income, Sex, Pills and Relationships: An Empirical Study for Argentina
2016
We use 28 years of Argentina’s life satisfaction (LS) and happiness (HA) data to test the Easterlin Paradox and find out the actual determinants of happiness. Argentineans are happier now than in 1984, and the City of Buenos Aires leads in present rankings of happiness in Argentina. In the cross-section analysis, LS correlates with the satisfaction about the economic situation of households, but the satisfaction with family and time spent with loved ones have a higher explanatory power. When it comes to HA, high social class members do not always buy a ticket, but low class makes people sadder. Nontraditional variables – pills for mental stress and sex – were also studied.
Paradoxical social representations of linky smart meters and privacy paradox
2021
Consumer participation to electricity consumption reduction (ECR) has become a major challenge in a context of Energy Transition. The Linky french Smart Meter, which use contributes to ECR, is confronted to many controversies reflecting the social legitimation at stake which underlies its evaluation. This article proposes to study privacy paradox regarding Linky Smart Meter use, mobilizing the conceptual background of consumer psychological empowerment. In that aim, a social representation analysis was conducted involving 271 respondents. Results highlight, on one hand, a privacy paradox involving 3 out of the 4 dimensions of psychological empowerment, and on another hand, the presence of m…
Co-evolution between trust in teachers and higher education toward digitally-rich learning environments
2017
Based on a powerful notion that the quality of higher education is crucial for innovation in digital economy and that such quality is subject to a conception of trust in teachers to deliver good education and advancement of information and communication technology (ICT), the dynamism of co-evolution between them was analyzed. Using a unique dataset representing the above system consisting of the rate of trust in teachers providing good education in the context of quality of education and their social status, of the level of higher education and the state of ICT advancement toward digitally-rich learning environments, an empirical numerical analysis of 20 countries was attempted. These count…
