A compilation of papers presented at the 2003 European Summer Meeting of the Association for Symbolic Logic, Logic Colloquium '03 includes tutorials and research articles from some of the world's preeminent logicians. One article is a tutorial on finite model theory and query languages that lie between first order and second order logic. The other articles cover current research topics in all areas of mathematical logic, including Proof Theory, Set Theory, Model Theory, and Computability Theory, and Philosophy.

In this volume, different aspects of logics for dependence and independence are discussed, including both the  logical and computational aspects of dependence logic, and also applications  in a number of areas, such as statistics, social choice theory, databases, and computer security.  The contributing authors represent leading experts in this relatively new field, each of whom was invited to write a chapter based on talks given at seminars held at the Schloss Dagstuhl Leibniz Center for Informatics in Wadern, Germany (in February 2013 and June 2015) and an Academy Colloquium at the Royal Netherlands Academy of Arts and Sciences (March 2014).  Altogether, these chapters provide the most up-to-date look at this developing and highly interdisciplinary field and will be of interest to a broad group of logicians, mathematicians, statisticians, philosophers, and scientists. Topics covered includea comprehensive survey of many propositional, modal, and first-order variants of dependence logic;new results concerning expressive power of several variants of dependence logic with different sets of logical connectives and generalized dependence atoms;connections between inclusion logic and the least-fixed point logic;an overview of dependencies in databases by addressing the relationships between implication problems for fragments of statistical conditional independencies, embedded multivalued dependencies, and propositional logic;various Markovian models used to characterize dependencies and causality among variables in multivariate systems;applications of dependence logic in social choice theory; andan introduction to the theory of secret sharing, pointing out connections to dependence and independence logic.

This book comprises revised full versions of lectures given during the 9th European Summer School in Logic, Languages, and Information, ESSLLI'97, held in Aix-en-Provence, France, in August 1997. The six lectures presented introduce the reader to the state of the art in the area of generalized quantifiers and computation. Besides an introductory survey by the volume editor various aspects of generalized quantifiers are studied in depth.

Edited in collaboration with FoLLI, the Association of Logic, Language and Information this book constitutes the refereed proceedings of the 23rd Workshop on Logic, Language, Information and Communication, WoLLIC 2016, held in Puebla, Mexico, in August 2016.The 23 contributed papers, presented together with 9 invited lectures and tutorials, were carefully reviewed and selected from 33 submissions. The focus of the workshop is to provide a forum on inter-disciplinary research involving formal logic, computing and programming theory, and natural language and reasoning.

Pasifismia 2 500 vuotta! Väkivalta ja terrorismi herättävät vaikeita kysymyksiä. Pasifisti ei kuitenkaan alistu, vaan toimii. Kirja opettaa ymmärtämään, kuinka rauhanomaisesti kohdata väkivaltainen ihminen. Kirjoittamassa muun muassa Mahatma Gandhi, Henry Thoreau, Leo Tolstoi ja Kurt Vonnegut.Suurin sielua uhkaava vaara on lähtöisin siitä itsestään ja tämän vaaran voittaminen antaa meille voimaa voittaa koko maailma.– Mahatma Gandhi

Mitkä ovat yleisesti hyväksytyt loogisen päättelyn periaatteet? Mitkä ovat menetelmät, joilla oikea päättely voidaan erottaa väärästä? Miksi jokin väite seuraa hyväksytyistä oletuksista, kun taas jokin toinen väite ei seuraa? Johdatus logiikkaan vastaa näihin kysymyksiin. Kirja antaa lukijalle peruskäsitteet ja työvälineet loogisesti oikean päättelyn ymmärtämiseen. Lukuisten esimerkkien ja tehtävien avulla lukija harjaantuu loogisen päättelyn suorittamiseen. Kirjassa käsitellään myös yleistettyjä kvanttoreita, äärettömiä kieliä, konstruktiivista ja moniarvologiikkaa. Johdatus logiikkaan on tarkoitettu lähinnä matematiikan ja tietojenkäsitteluopin opiskelijoille. Sen lukeminen ei kuitenkaan edellytä kummaltakaan alalta esitietoja. Siksi kirja soveltuu myös muille logiikasta kiinnostuneille.
