Simulating multilevel dynamics of antimicrobial resistance in a membrane computing model

2019

Membrane computing is a bio-inspired computing paradigm whose devices are the so-called membrane systems or P systems. The P system designed in this work reproduces complex biological landscapes in the computer world. It uses nested “membrane-surrounded entities” able to divide, propagate, and die; to be transferred into other membranes; to exchange informative material according to flexible rules; and to mutate and be selected by external agents. This allows the exploration of hierarchical interactive dynamics resulting from the probabilistic interaction of genes (phenotypes), clones, species, hosts, environments, and antibiotic challenges. Our model facilitates analysis of several aspects…

Anticipated future of Latvia and Russia during a global economic crisis: A mixed methods perspective

2014

This cross-cultural study explored subjective predictors of more positive evaluation of the future of the country during a global socioeconomic crisis. A sequential mixed-method design was chosen for an exploration of students? expectations in Russia and Latvia as countries contrasting in macro-contextual conditions. In 2009, Study 1 was designed as a thematic analysis of essays on topic ?The Future of Latvia/Russia?. The results demonstrated that the future of a country is anticipated by taking into account external influences, the present of the country, and its perceived power and stability. In 2011, Study 2 involved these themes as independent variables in a multiple regression model. T…

Plasticity in the trophic niche of an invasive ant explains establishment success and long‐term coexistence

2021

Invasive species are one of the main threats to biodiversity worldwide and the processes enabling their establishment and persistence remain poorly understood. In generalist consumers, plasticity in diet and trophic niche may play a crucial role in invasion success. There is growing evidence that invasive ants, in particular, occupy lower trophic levels in their introduced range compared to the native one, but evidences remain fragmented. We conducted stable isotope analysis at five locations distributed on two continents to infer the trophic position of the invasive ant Formica paralugubris in the native and introduced part of the range. This species forms large colonies and can be a vorac…

Neurobiology of performance anxiety:A new approach

2016

The aim of this study is to investigate the neurobiology of stress/emotionality, creating a multidisciplinary assessment model, which can help to provide psychological and physiological responses depending on the genetic background related to sport performances, social closeness and performance anxiety management in team sports. We enrolled 20 female volleyball players aged 13 ± 1 years old played in two different teams during a regional championship final. Saliva collection was carried out before and after the match. In order to evaluate the neuroendocrine effectors involved in stress and performance, we analyzed cortisol and progesterone levels through Elisa standard kit as well as HSP70 …

De la performance musicale dans la Guyane traditionnelle : expression cognitive singulière d?une musique-verbe

2021

Guianese culture and traditional music, here evoked, are various. It is more a transcultural process that, along centuries, gave an original result born in the Americas, in Guiana in this case. It is a form of refoundation, of recreation of cultures and new human beings generally called Creoles. The musical performance, that I study here, is the echo of social and cultural space of this reformulation of thought, life, and conception of the world. It is, as well, a mean of transposition and transformation of the values issued of diverse sources and categories. It is in no way a second-rate cultural practice, as it is the place where were born philosophies and actions for common life as well …

Towards Automatic Testing of Reference Point Based Interactive Methods

2016

In order to understand strengths and weaknesses of optimization algorithms, it is important to have access to different types of test problems, well defined performance indicators and analysis tools. Such tools are widely available for testing evolutionary multiobjective optimization algorithms. To our knowledge, there do not exist tools for analyzing the performance of interactive multiobjective optimization methods based on the reference point approach to communicating preference information. The main barrier to such tools is the involvement of human decision makers into interactive solution processes, which makes the performance of interactive methods dependent on the performance of huma…

An Artificial Decision Maker for Comparing Reference Point Based Interactive Evolutionary Multiobjective Optimization Methods

2021

Comparing interactive evolutionary multiobjective optimization methods is controversial. The main difficulties come from features inherent to interactive solution processes involving real decision makers. The human can be replaced by an artificial decision maker (ADM) to evaluate methods quantitatively. We propose a new ADM to compare reference point based interactive evolutionary methods, where reference points are generated in different ways for the different phases of the solution process. In the learning phase, the ADM explores different parts of the objective space to gain insight about the problem and to identify a region of interest, which is studied more closely in the decision phas…

Attitudes toward and motivation for PE: who collects the benefits of the subject?

2014

Background and purpose: Due to attitudinal and motivational aims in the national curriculum, and to lack of research on adolescents' experiences with physical education (PE) in Norway, the purposes of this study were to (1) attain data on attitudes toward PE and self-determined motivation for PE among a representative sample of adolescents (N = 2010) in middle school (grade 8–10/age 13–15) and high school (grade 11–13/age 16–19) in Norway, and (2) to explore the relationship between involvement in movement activities outside school and self-determined motivation in PE. Findings: The results showed that 43% of the adolescents were not happy with how PE is taught in Norwegian schools, and tha…
