A simple proof of the polylog counting ability of first-order logic

2007

The counting ability of weak formalisms (e.g., determining the number of 1's in a string of length N ) is of interest as a measure of their expressive power, and also resorts to complexity-theoretic motivations: the more we can count the closer we get to real computing power. The question was investigated in several papers in complexity theory and in weak arithmetic around 1985. In each case, the considered formalism (AC 0 -circuits, first-order logic, Δ 0 ) was shown to be able to count up to a polylogarithmic number. An essential part of the proofs is the construction of a 1-1 mapping from a small subset of {0, ..., N - 1} into a small initial segment. In each case the expressibility of …

Asymptotics for Graded Capelli Polynomials

2014

The finite dimensional simple superalgebras play an important role in the theory of PI-algebras in characteristic zero. The main goal of this paper is to characterize the T 2-ideal of graded identities of any such algebra by considering the growth of the corresponding supervariety. We consider the T 2-ideal Γ M+1,L+1 generated by the graded Capelli polynomials C a p M+1[Y,X] and C a p L+1[Z,X] alternanting on M+1 even variables and L+1 odd variables, respectively. We prove that the graded codimensions of a simple finite dimensional superalgebra are asymptotically equal to the graded codimensions of the T 2-ideal Γ M+1,L+1, for some fixed natural numbers M and L. In particular csupn(Γk2+l2+1…

A Test of the Relationship Between Argumentativeness and Individualism/Collectivism in the United States and Finland

2016

This study explored relationships between argumentativeness and collectivism/individualism in Finland and the United States. Data were gathered in the United States (n = 412) and Finland (n = 261). The analysis suggested: (a) collectivism was negatively correlated with argumentativeness, (b) individualism was positively correlated with argumentativeness, and (c) Finnish participants reported lower levels of argumentativeness than Americans. Cultural differences between the United States and Finland are discussed as reasons for the differences between the nations on argumentativeness.

Smart city. Four approaches to the concept of understanding

2020

The paper analyzes the rhetoric of the smart city (SC) concept in order to recognize, categorize, and describe different perspectives of understanding the notion. Four approaches to the SC concept were isolated: three affirmative, and one rejecting. The approaches present a different understanding of the SC and indicate different elements creating urban ‘smartness.’ Despite differences, there is one common goal in every affirmative approach: to improve the quality of urban life. It is achieved through activities covering five dimensions distinguished within affirmative approaches. Together they can serve, i.e.,as a framework for SC case study analyses.

The Playing Brain. The Impact of Video Games on Cognition and Behavior in Pediatric Age at the Time of Lockdown: A Systematic Review

2021

A growing number of children and adolescents play video games (VGs) for long amounts of time. The current outbreak of the Coronavirus pandemic has significantly reduced outdoor activities and direct interpersonal relationships. Therefore, a higher use of VGs can become the response to stress and fear of illness. VGs and their practical, academic, vocational and educational implications have become an issue of increasing interest for scholars, parents, teachers, pediatricians and youth public policy makers. The current systematic review aims to identify, in recent literature, the most relevant problems of the complex issue of playing VGs in children and adolescents in order to provide sugges…

The implications of the local context in global virtual education

2012

<input id="gwProxy" type="hidden" /><input id="jsProxy" onclick="if(typeof(jsCall)=='function'){jsCall();}else{setTimeout('jsCall()',500);}" type="hidden" /><p>This paper investigates how features in students’ everyday life influence their participation in online global collaboration, and it suggests that students’ local context should be recognised as a significant part of their educational space. In this exploratory case study of students engaged in a global online master’s programme, the discussion is organised under three main headings: the social, material, and cultural dimensions of students’ daily life. The paper shows how the influence of the students’ local contex…

From putative genes to temperament and culture: Cultural characteristics of the distribution of dominant affective temperaments in national studies

2010

Abstract Background Affective temperaments may carry distinct evolutionary advantages both on the individual or a group level, so we can expect that in different cultural and national samples the frequency of dominant affective temperaments will show characteristic differences. The aim of the present study was to investigate the characteristics of distribution of dominant affective temperaments in different national studies of general non-clinical population. Method In our study we included six studies published in different countries around the world (Argentina, Germany, Hungary, Korea, Portugal, and Lebanon) which investigated a large sample of non-clinical population using TEMPS-A, and r…

Empathy, emotional intelligence, and communication in Nursing: The moderating effect of the organizational factors

2020

Objective: to evaluate the relation and the moderating effect of the organizational factors on the attitudes towards communication, empathy, and emotional intelligence in the nurses. Method: a cross-sectional study was conducted with a convenience sample of 268 nurses from Valencia, Spain. The attitudes towards communication were evaluated by means of the specifically designed instrument, those towards empathy with the Jefferson’s Scale of Empathy for Nursing Students, and those towards emotional intelligence by means of the Trait Meta-Mood Scale, consisting of 24 items. The effect of the studied variables was assessed by means of ANOVA, multiple linear regression models were applied, and t…

Cross-national cultural values and nascent entrepreneurship

2016

This article, differentiating between factual and normative values, investigates the links between national culture and entrepreneurial activity in 24 countries based on 154 observations. We test hypotheses on the relationship between national culture—measured by Global Leadership and Organizational Behavior Effectiveness (GLOBE)—and nascent entrepreneurship as represented by Global Entrepreneurship Monitor (GEM). Both the GEM and the GLOBE databases are robust in terms of forming empirical connections between factual and normative culture and entrepreneurship at the country level. Using these two separate databases to examine our hypotheses enables us to avoid the methodological biases th…
