3. 2. On Aligning Returns Management with the E-commerce Strategy to Increase Effectiveness

   Författare :Klas Hjort; Högskolan i Borås; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Returns management; supply chain management; alignment; case study; experimental research; gatekeeping; avoidance; reverse logistics; strategy; e-commerce; Logistik; Handel och IT; Bussiness and IT;

   Sammanfattning : The returns management (RM) process has traditionally been seen as a value recovery process, which has resulted in an efficiency focus in the returns flow. This thesis present, the effects on a fashion e-commerce organisation, which is underprioritising or neglecting RM in general and consumer returns specifically. LÄS MER

4. 3. Returns Avoidance and Gatekeeping to Enhance E-commerce Performance

   Författare :Klas Hjort; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; returns management; customer service; demand chain management; e-commerce;

   Sammanfattning : The mail order business was once a traditional method of selling and distributing clothes, and other commodities, to customers. Now, the e-commerce trend, with more sophisticated techniques of marketing, selling, and distributing goods, has not only challenged the traditional mail order system, it seems also that the traditional retail chain and even fashion chains are being challenged.

5. 4. Microactuators for Powerful Pumps

   Författare :Roger Bodén; Klas Hjort; Jan-Åke Schweitz; Johan Nilsson; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; µTAS; chromatography; high pressure; lab-on-a-chip; microactuator; microdispenser; micropump; on-chip; paraffin; PCM; point-of-care; Engineering physics; Teknisk fysik;

   Sammanfattning : When paraffin wax melts it exhibits a large, relatively incompressible volume expansion. This can be used in microactuators for strong and large displacements, a rare combination among actuators. Furthermore, paraffin is inexpensive, inert and environmentally friendly, as well as easily processed and actuated. LÄS MER
