  1. 1. Specifying and Operationalizing an Organizational Theory of Crowdsourcing

    Detta är en avhandling från Luleå : Luleå University of Technology

    Författare :John Prpic; Luleå tekniska universitet.; [2017]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; crowdsourcing; organizations; theory specification; theory operationalization; theory validation; Industrial Marketing; Industriell marknadsföring;

    Sammanfattning : Introduction: Despite rapid developments across multiple areas of research and practice, an organizational-level theory of Crowdsourcing has yet to emerge.Objectives: Therefore, this thesis has two major objectives; 1) specify the boundaries, constructs, and relationships of an organizational-level theory of Crowdsourcing, and 2) begin the theoretical validation process by operationalizing the theory for new exploratory, explanatory, and conceptual research.

  2. 2. Network models with applications to genomic data: generalization, validation and uncertainty assessment

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :José Sánchez; Göteborgs universitet.; Gothenburg University.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inverse covariance matrix; precision matrix; graphical models; high-dimension; low-sample; networks; sparsity; fused lasso; elastic net; cancer; TCGA pan cancer analysis; online resource; discriminant analysis; classification;

    Sammanfattning : The aim of this thesis is to provide a framework for the estimation and analysis of transcription networks in human cancer. The methods we develop are applied to data collected by The Cancer Genome Atlas (TCGA) and supporting simulations are based on derived models in order to reflect real data structure. LÄS MER

  3. 3. On Safety Validation of Automated Driving Systems using Extreme Value Theory

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Daniel Åsljung; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Verification; Autonomous Vehicles; Performance Evaluation; Automotive;

    Sammanfattning : Autonomous vehicles are expected to bring safer and more convenient transports in the future. When the system in the vehicle takes care of the driving, the driver is free to spend time on other things. LÄS MER

    Detta är en avhandling från Umeå : Institutionen för beteendevetskapliga mätningar, Umeå universitet

    Författare :Hanna Eklöf; Umeå universitet.; [2006]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; test-taking motivation; TIMSS 2003; validity; construct validation; measurement; expectancy-value theory; self-concept; task value; factor analysis; eighth-grade students; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Sammanfattning : The main objective of this thesis was to explore issues related to student achievement motivation in the Swedish TIMSS 2003 (Trend in International Mathematics and Science Study) context. The thesis comprises of five empirical papers and a summary. LÄS MER

  5. 5. Estimation and Model Validation of Diffusion Processes

    Detta är en avhandling från Umeå : Institutionen för beteendevetskapliga mätningar, Umeå universitet

    Författare :Erik Lindström; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Estimation and Model Validation of Diffusion Processes Abstract The main motivation for this thesis is the need for estimation and model validation of diffusion processes, i.e. stochastic processes satisfying a stochastic differential equation driven by Brownian motion. LÄS MER
