2. 21. United in Diversity : A Physiological and Molecular Characterization of Subpopulations in the Basal Ganglia Circuitry

   Author : Thomas Viereckel; Åsa Wallén-Mackenzie; Åsa Konradsson-Geuken; Erika Comasco; Per Svenningsson; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Glutamate; Optogenetics; Amperometry; Histology; Midbrain; Subthalamic Nucleus; Parkinson s disease; Ventral Tegmental Area; Substantia Nigra; Co-release;

   Abstract : The Basal Ganglia consist of a number of different nuclei that form a diverse circuitry of GABAergic, dopaminergic and glutamatergic neurons. This complex network is further organized in subcircuits that govern limbic and motor functions in humans and other vertebrates. READ MORE

4. 22. Aspects on Interference and Diversity in Wireless Networks

   Author : Fredrik Florén; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikationsteknik; Telecommunication engineering; Elektronik och elektroteknik; Electronics and Electrical technology; feedback; multiuser communication; diversity; throughput; packet radio networks; Interference; frequency hop communication;

   Abstract : This thesis deals with two topics in wireless communications: interference between frequency-hopping (FH) networks, and multiuser diversity. The work on FH treats a system where FH is used to provide simultaneous access to the channel for multiple uncoordinated wireless networks. READ MORE

5. 23. Utilizing Diversity and Performance Measures for Ensemble Creation

   Author : Tuve Löfström; Högskolan i Skövde; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ensemble Learning; Machine Learning; Diversity; Artificial Neural Networks; Data Mining; Information Fusion; Computer science; Datavetenskap; Teknik; Technology;

   Abstract : An ensemble is a composite model, aggregating multiple base models into one predictive model. An ensemble prediction, consequently, is a function of all included base models. Both theory and a wealth of empirical studies have established that ensembles are generally more accurate than single predictive models. READ MORE

6. 24. Optimization beyond a single submodular function : Submodular optimization for ranking, decision trees and diversity

   Author : Guangyi Zhang; Aristides Gionis; Danupon Na Nongkai; Parinya Chalermsook; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Submodular optimization; Approximation algorithms; Ranking; Decision trees; Diversity; Datalogi; Computer Science;

   Abstract : Submodular functions characterize mathematically the ubiquitous ``diminishing-returns'’ property. They are widely used to describe core subjects in numerous applications, including economic utility, redundancy in information, spread of influence in social networks, and more. READ MORE

7. 25. Immigration, Social Cohesion, and the Welfare State : Studies on Ethnic Diversity in Germany and Sweden

   Author : Tina Goldschmidt; Jens Rydgren; Martin Hällsten; Peer Scheepers; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; welfare state; attitudes; intergroup relations; prejudice; deservingness; diversity; immigration; integration; unemployment; Sweden; Germany; Sociology; sociologi;

   Abstract : Can social cohesion and solidarity persist in the face of large-scale migration? One particularly contentious hypothesis states that native majorities will be unwilling to support the provision of government-funded welfare to those whom they do not consider to be part of their own sociocultural ingroup, especially when sociocultural or ethnic otherness and socioeconomic disadvantage overlap. Consequently, majorities’ willingness to accept disadvantaged immigrant groups as legitimate and trusted members of the welfare community is central to the social cohesion of societies diversifying through migration.
