1. 31. Environmental Impacts of Shared Mobility: Potential, Factors, and Assessments

   Författare :Ana Maria Arbelaez Velez; Internationella miljöinstitutet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shared mobility; Environmental impact; sustainable transportation; input and output analysis; Life Cycle Assessment LCA; demand-side solutions;

   Sammanfattning : Environmental impacts from passenger transportation continue to increase globally due to a rise in kilometers traveled and a shift to emission-intensive transportation modes (from public transportation and active modes such as walking and cycling to motorcycle and car ridership). The electrification of the passenger fleet, coupled with low-carbon energy sources, is expected to decrease some of the environmental impacts associated with passenger transportation, including local air pollution, greenhouse gas emissions and fuel depletion.

3. 32. Purchasing Power and Purchasing Strategies - Insights From the Humanitarian Sector

   Författare :Ala Pazirandeh; Teknisk logistik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Humanitarian logistics; Purchainsg; Resource dependency theory; Buyer-supplier power;

   Sammanfattning : In this dissertation, we discuss how buyers practice purchasing strategies in an asymmetric power situation favoring suppliers, and how their purchasing strategies practiced impact their purchasing power and buyer-supplier relationships. Organizations enter exchange relationships to access required resources not produced internally, and are exposed to uncertainty from not being able to fully control or predict flow of resources.

4. 33. Food in the Future : energy and transport in the food system

   Författare :Christine Wallgren; Lars Orrskog; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food technology; Livsmedelsteknik;

   Sammanfattning : This thesis explores possible future forms of a sustainable food supply system from an energy aspect. Particular attention is devoted to local food supply as a means to reduce energy use for transport. The thesis consists of a covering essay and three studies: one futures study of the entire food supply system and two case studies of local farming. LÄS MER

   Sammanfattning : As from 1686 it was decreed by law that all government regulations, orders, edicts and other information any government official wanted to make public, had to be read out to the people by the clergy from the pulpits of all churches in Sweden and Finland at the end of the sermon. The system of communication remained in full force until the end of the 19th century and was not finally abandoned until 1942. LÄS MER
