1. 1. Space in Proof Complexity

   Författare :Marc Vinyals; Jakob Nordström; Yehudayoff Amir; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; proof complexity; resolution; polynomial calculus; cutting planes; space complexity; computational complexity; pebble games; communication complexity; CDCL; Computer Science; Datalogi;

   Sammanfattning : ropositional proof complexity is the study of the resources that are needed to prove formulas in propositional logic. In this thesis we are concerned with the size and space of proofs, and in particular with the latter.Different approaches to reasoning are captured by corresponding proof systems. LÄS MER

3. 2. Meaning and Action in Sustainability Science : Interpretive approaches for social-ecological systems research

   Författare :Simon West; Lisen Schultz; Lorrae van Kerkhoff; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Meaning; interpretive; social-ecological system; complexity; science-policy interface; transformation; sustainability science methodology; Sustainability Science; vetenskap om hållbar utveckling;

   Sammanfattning : Social-ecological systems research is interventionist by nature. As a subset of sustainability science, social-ecological systems research aims to generate knowledge and introduce concepts that will bring about transformation. Yet scientific concepts diverge in innumerable ways when they are put to work in the world. LÄS MER

4. 3. Text Representations and Explainability for Political Science Applications

   Författare :Denitsa Saynova; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Political Science; Explainability; NLP; Representation;

   Sammanfattning : This work explores the utility of natural language processing approaches for the study of political behavior by examining two main aspects - representation and explainability. We investigate how current representation approaches capture politically relevant signals in a proportional representation system. LÄS MER

5. 4. Reconstruction planning in post-conflict zones : Bosnia and Herzegovina and the international community

   Författare :Tigran Hasic; Göran Cars; Wakter Leal Filho; KTH; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Political science; reconstruction planning; post-conflict zones; bosnia and herzegovina; international community; complexity and systems thinking; grounded theory; Statsvetenskap; Political science; Statsvetenskap;

   Sammanfattning : The history of mankind has been plagued by an almost continuous chain of various armed conflicts - local, regional, national and global - that have caused horrendous damage to the social and physical fabric of cities. The tragedy of millions deprived by war still continues. LÄS MER

7. 5. Cell adhesion proteins in different invasive patterns of colon carcinomas : a morphometric and molecular genetic study

   Författare :Victoria Hahn-Strömberg; Lennart Franzén; Richard Palmqvist; Örebro universitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; colon carcinoma; growth pattern; tight junction; Complexity Index; cell adhesion; E-cadherin; Beta-catenin; Occludin; Claudin.; Medicine; Medicin; Biomedicin; Biomedicine;

   Sammanfattning : Colorectal carcinoma is the second most common type of cancer in both men and women in Sweden. Cancer of the colon and rectum are often considered together and their ten year survival rate is approximately 50 – 60 % depending on sex and location. LÄS MER
