3. 27. DFT calculations of initial localized corrosion of aluminum : Influence of aqueous ad-layer, chloride ions, and intermetallic particles

   Författare :Min Liu; Jinshan Pan; Ying Chen; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aluminum alloys; alumina; chloride; surface adsorption; aqueous ad-layer; localized corrosion; corrosion initiation; work function; micro-galvanic effect; density-functional theory; Volta potential; scanning kelvin probe force microscopy; Kemi; Chemistry;

   Sammanfattning : Localized corrosion of aluminum (Al, here including Al alloys) involves a series of physico-chemical processes at the interface between the metal and the aqueous ad-layer or the aqueous solution. The mechanisms that govern localized corrosion are quite complex and have been the subject of many experimental studies. LÄS MER

4. 28. Vacua in String Theory : de Sitter Space and Stability in Flux Compactifications

   Författare :Sergio C. Vargas; Ulf Danielsson; Alessandro Tomasiello; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; String theory; Cosmology; Flux Compactifications; Landscape; Swampland;

   Sammanfattning : Our understanding of cosmology has evolved radically in the last decades. Current models demand the presence of dark energy in our universe and the most favored candidate behind this component is a small positive cosmological constant that characterizes a de Sitter (dS) spacetime.

5. 29. Enabling Perceptions of Management Controls : Evidence from International Development Programs

   Författare :Raymond Ndikumana; Tobias Johansson-Berg; Lili-Anne Kihn; Örebro universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Enabling control; perceptions; development programs; PLS-structural equation modeling; empowerment; performance;

   Sammanfattning : A key challenge for management accounting and control is the extent to which the control’s intentions correlate with how it is received and perceived by those who are subject to it. Building on Adler & Borys’ (1996) enabling and coercive bureaucracy, this thesis explores the role of perception; that is, local actors consider controls as enabling their work instead of privileging only those at the top.

7. 30. Costs and Benefits of Delegation : Managerial Discretion as a Bridge between Strategic Management and Corporate Governance

   Författare :Yuliya Ponomareva; Sven-Olof Yrjö Collin; Ruth Aguilera; Linnéuniversitetet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Managerial discretion; board of directors; agency theory; delegation; control; transition economy; Sweden; Ekonomistyrning; Ekonomistyrning;

   Sammanfattning : This dissertation addresses the question of effective delegation, exploring it through the concept of managerial discretion (i.e., a latitude of managerial actions, which lie in the zone of shareholders’ acceptance). LÄS MER
