  1. 1. Livelihood Implications of Large-Scale Land Concessions in Mozambique : A case of family farmers’ endurance

    Författare :Juliana Porsani; Kari Lehtilä; Rickard Lalander; Lowe Börjeson; Randi Kaarhus; Södertörns högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Large-scale land acquisitions; land concessions; land grabs; livelihoods; family farmers; peasants; gender; community consultations; popular deliberation; cultural ecosystem services; Mozambique; Lower Limpopo Valley; Environmental Studies; Miljövetenskapliga studier;

    Sammanfattning : This thesis examines the process and the implications of large-scale land acquisitions (LSLAs) for local livelihoods, especially the livelihoods of those who make a living from farming. These individuals were historically known as peasants and are now more commonly referred to as smallholders, small-scale farmers or family farmers. LÄS MER

  3. 2. Inducing large-scale diffusion of innovation : An integrated actor- and system-level approach

    Författare :Ingrid Mignon; Anna Bergek; Johanna Nählinder; Volker Hoffmann; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Innovation; large-scale diffusion; adopters; actor; system; drivers; challenges; motives; strategies; policies; renewable electricity; technology; intermediaries;

    Sammanfattning : In order for the innovation process to be successful, not only do innovations need to be developed and reached the market, but, once they are available for users, they have to spread on a large scale. In the innovation literature, a complete explanation is lacking of why some innovations reach a phase of large-scale diffusion faster than others, including both actor- and system-level components.

  4. 3. Making Sense of Large-scale Cyber Incidents : International Cybersecurity Beyond Threat-based Security Perspectives

    Författare :Sarah Backman; Mark Rhinard; Arjen Boin; Tim Stevens; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; International cybersecurity; large-scale cyber incidents; securitization; cybersecurity governance; International Relations; internationella relationer;

    Sammanfattning : Large-scale cyber incidents have figured prominently in securitizing speech acts over the last decade. This thesis demonstrates how conceptualizations of cybersecurity as a public security problem connects to and shapes cybersecurity governance in national and international settings. LÄS MER

  5. 4. Accelerating Convergence of Large-scale Optimization Algorithms

    Författare :Euhanna Ghadimi; Mikael Johansson; Angelia Nedich; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Convex optimization; Large-scale systems; First-order methods; Convergence analysis; ADMM; Optimization algorithms; Electrical Engineering; Elektro- och systemteknik; Matematik; Mathematics;

    Sammanfattning : Several recent engineering applications in multi-agent systems, communication networks, and machine learning deal with decision problems that can be formulated as optimization problems. For many of these problems, new constraints limit the usefulness of traditional optimization algorithms. LÄS MER

  7. 5. Distributed Stochastic Programming with Applications to Large-Scale Hydropower Operations

    Författare :Martin Biel; Mikael Johansson; Lennart Söder; David Woodruff; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stochastic programming; distributed; algorithms; large-scale; optimization; hydropower; software; julia language; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Stochastic programming is a subfield of mathematical programming concerned with optimization problems subjected to uncertainty. Many engineering problems with random elements can be accurately modeled as a stochastic program. In particular, decision problems associated with hydropower operations motivate the application of stochastic programming. LÄS MER
