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…

L'anfiteatro romano di Termini Imerese : ricostruzioni virtuali e vicende storico/architettoniche del sito urbano

2018

The work we present is inspired by the results of an architectural survey that was carried out on the architectural remains of the Roman Amphitheater of Termini Imerese, in order to its possible conjectural reconfiguration and three-dimensional remodeling in a VRML or augmented-reality context. All this has been thought to benefit the development of cultural and archaeological tourism in the site itself. The approach to the site and to the ancient building has, however, focused on urban and territorial analysis since the first inspections, considering mainly the peculiarities that distinguish the historical / architectural vicissitudes of the site. In the Medieval Age the Jewish Quarter was…

Anemia management in end stage renal disease patients undergoing dialysis: a comprehensive approach through machine learning techniques and mathemati…

2016

Kidney impairment has global consequences in the organism homeostasis and a disorder like Chronic Kidney Disease (CKD) might eventually exacerbates into End Stage Renal Disease (ESRD) where a complete renal replacement therapy like dialysis is necessary. Dialysis partially reintegrates the blood ltration process; however, even when it is associated to a pharmacological therapy, this is not su fficient to completely replace the renal endocrine role and causes the development of common complications, like CKD secondary anemia (CKD-anemia) The availability of exogenous Erythropoiesis Stimulating Agents (ESA, synthetic molecules with similar structure and same mechanism of action as human eryth…

Simulating Secularities: Challenges and Opportunities in the Computational Science of (Non)Religion

2021

This article provides scholars of nonreligion and secularism with an introduction to some of the major opportunities and challenges associated with the growing application of computational methods to the phenomena they study. It also illustrates these opportunities and challenges by describing several overlapping research projects and some of the models of (non)religion they have produced. Finally, the article addresses some of the significant philosophical issues surrounding the use of computer modeling and simulation, focusing on the ethical and epistemological concerns that these tools often raise. I invite scholars of nonreligion to consider adding these techniques to their methodologic…

Computer Modeling in Philosophy of Religion

2019

AbstractHow might philosophy of religion be impacted by developments in computational modeling and social simulation? After briefly describing some of the content and context biases that have shaped traditional philosophy of religion, this article provides examples of computational models that illustrate the explanatory power of conceptually clear and empirically validated causal architectures informed by the bio-cultural sciences. It also outlines some of the material implications of these developments for broader metaphysical and metaethical discussions in philosophy. Computer modeling and simulation can contribute to the reformation of the philosophy of religion in at least three ways: b…

Attitudes toward sad music are related to both preferential and contextual strategies.

2015

Music-related sadness and its paradoxical pleasurable aspects have puzzled researchers for decades. Previous studies have highlighted the positive effects of listening to sad music and the listening strategies that focus on mood-regulation. The present study explored people’s attitudes toward sad music by focusing on a representative sample of the Finnish population. Three hundred and fifty-eight participants rated their agreement with 30 statements concerning attitudes toward sad music. The ratings were subjected to factor analysis, resulting in 6 factors explaining 51% of the variance (RMSEA = 0.049). The factors were labeled Avoidance, Autobiographical, Revival, Appreciation, Intersubjec…

Are Facebook brand community members truly loyal to the brand?

2015

Investigates two Facebook brand communities and their relationship with loyalty.Community commitment is associated with community promotion behavior and loyalty.Community promotion behavior is associated with different types of loyalty.User activity in Facebook has little or no effect on brand loyalty. This study examines members of Facebook brand communities and tests the relationships between their commitment to the community and brand loyalty. A conceptual model on the linkages between brand community commitment, community promotion behavior and brand loyalty including attitudinal loyalty, repurchase intention and positive word-of-mouth (WOM) is developed and tested with two samples. Dat…

Sexism and Aggression in Adolescence.¿How Do They Relate to Perceived Academic Achievement?

2018

Sexist attitudes are rooted in patriarchal structures, which uphold traditional gender stereotypes, and which are still found in society today. Scholars have found gender differences in perceived academic achievement, with girls performing better than boys, and negative relationships between sexism and perceived academic achievement. Moreover, perceived academic achievement and sexist attitudes have been associated with aggression and different kinds of violence. This study examined the associations between sexist attitudes and perceived academic achievement (using self-report data). The study also assessed the mediating role of physical and verbal aggression in the relationship between sex…
