3. 12. 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. 13. The effects of stage-specific differences in energetics on community structure

   Sammanfattning : When intraspecific individuals differ in resource intake, scramble competition occurs among inferior individuals growing food-dependently. Scramble can be released through predation mortality. As a consequence of this release, production rates in inferior individuals increase and biomass overcompensation in the subsequent life-stages may occur. LÄS MER
