Kundklubbar och lojalitetsprogram i ett relationsmarknadsföringsperspektiv

Kundklubbar och lojalitetsprogram, marknadsföringsåtgärder som snabbt anammats inom de flesta branscher, utgör strategiska och taktiska åtaganden som direkt stöder en relationsmarknadsföringsansats i företag. Turistbranschen är inget undantag och idag ser vi hur även researrangörer utvecklat egna kundklubbar. Den frekvens med vilken finländska turister köper paketresor till "södern" per år ligger långt från den frekvens med vilken affärsresenärerna utnyttjar flygbolagens lojalitetsprogram. Trots det finns det ingen diskussion som belyser frågan hur väl relationsmarknadsföringsteorier utvecklade för marknader med hög köpfrekvens (flygbolagens lojalitetsprogram) är användbara på marknader där köpfrekvensen är lägre (t.ex. researrangörsbranschen). I denna artikel sammankopplas relationsmarknadsföringsteorier med teorier om lojalitetsprogram och kundklubbar. Artikeln syftar till att fördjupa förståelsen för lojalitetsprogrammens och kundklubbarnas relevans i en relationsmarknadsföringsansats. Ur diskussionen härleds forskningsfrågor som kan användas för att identifiera nya centrala forskningsområden. Artikeln fokuserar på den forskning som finner sin empiriska förankring i turistbranschen.

Enhancement of workability in AZ31 alloy-processing maps: Part I,castmaterial

Processing maps developed on the basis of the Dynamic Materials Model provide valuable information that might help the metal working industry in solving problems related to workability and microstructural control in commercial alloys. In this research, the processing maps for an as-cast AZ31 magnesium alloy are presented. The results are validated via microstructural observations, clearly delineating safe and unsafe regimes for further process design of this alloy.

Characterization of human symptomatic rotavirus isolates MP409 and MP480 having ‘long’ RNA electropherotype and subgroup I specificity, highly related to the P6[1],G8 type bovine rotavirus A5, from Mysore, India

In an epidemiological study of symptomatic human rotaviruses in Mysore, India during 1993 and 1994, isolates MP409 and MP480 were isolated from two children suffering from severe, acute dehydrating diarrhea. Both isolates exhibited 'long' RNA pattern and subgroup I specificity suggesting the likelihood of their animal origin. Both isolates did not react with monoclonal antibodies (MAbs) specific for serotypes G1 to G6 as well as CIO. To determine the genetic origin of these isolates, complete nucleotide sequences of genes encoding the outer capsid proteins VP4 and VP7, nonstructural proteins NSP1 and NSP3 and viral enterotoxin protein NSP4 from MP409 and partial sequences of genes from MP480 were determined. Comparison of the 5' and 3' terminal sequences of 250 nucleotides revealed complete identity of the gene sequences in both strains suggesting that MP409 and MP480 are two different isolates of a single strain. Comparison of the nucleotide and deduced amino acid sequences of VP4, VP7, NSP1 and NSP3 of MP409 with published sequences of strains belonging to different serotypes revealed that both outer capsid proteins VP4 and VP7 and NSP1 are highly related to the respective proteins from the P6[1], G8 type bovine rotavirus A5 isolated from a calf with diarrhoea in Thailand and that the NSP3 is highly homologous to that of bovine rotaviruses. The NSP 1 protein showed greatest sequence identity with NSP4s belonging to the KUN genetic group to which NSP4s from human G2 type strains and bovine rotaviruses belong. MP409 and MP480 likely signify interspecies transmission of P6[1], G8 type strains from cattle to humans and represent the first P6[1] type rotaviruses isolated in humans. These and our previous studies on the asymptomatic neonatal strain I321 are of evolutionary and epidemiological significance in the context of close association of majority of the Indian population with cattle.

Peptide hairpin nucleation with the obligatory Type I' beta-turn Aib-(D)Pro segment

The alpha-aminoisobutyric acid-D-proline (Aib-(D)Pro) dipeptide is an obligatory Type I' beta-turn forming segment that nucleates hairpin formation.
