Purpose This paper aims to examine the relationships between locus of attribution, recovery justice perceptions, recovery satisfaction and repurchase intention after a B2B service failure. Design/methodology/approach Structural equation modeling was used to analyze 300 customer surveys from hospitality businesses. The connections between the selected variables were explored through path analysis using AMOS 24. Findings Based on the results, the more that business customers blame their wholesalers after a service failure, the less they perceive the procedures in the recovery process as fair. Findings also indicate that in the recovery process, interactional connections through fair treatment and inclusion of customer opinions are important to achieve high recovery satisfaction levels. Moreover, if business customers perceive the monetary compensation provided as fair, their recovery satisfaction increases, and recovery satisfaction then helps to retain these business customers after a service failure. Research limitations/implications Starting from the locus of blame, this study highlights the after-failure calculation that business customers make in considering their recovery justice perceptions and the resulting satisfaction level. Practical implications The findings have relevance for B2B relationships. This study provides practical processes for failure and recovery management in B2B settings, especially for wholesale providers who function as resellers rather than as manufacturers. Originality/value The contributions from this study are largely due to examining B2B service failure and recovery as a process that starts at the pre-recovery stage with the locus of attribution followed by recovery justice perceptions. Whereas other studies have focused more on justice perceptions, the authors go back a step in the recovery process to better understand the antecedents of repurchase intention in B2B transactions.

Objectives:The biochemical effects of thiamine pyrophosphate on ischemia-reperfusion (IR) induced oxidative damage and DNA mutation in rat kidney tissue were investigated, and compared to thiamine.Materials and Methods:Rats were divided into four groups: Renal ischemia-reperfusion (RIR); thiamine pyrophosphate + RIR (TPRIR); thiamine + RIR (TRIR); and sham group (SG).Results:The results of biochemical experiments have shown that malondialdehyde (MDA) levels in rat kidney tissue after TRIR and TPRIR treatment were 7.2 ± 0.5 (P > 0.05) and 3.3 ± 0.3 (P < 0.0001) μmol/g protein, respectively. The MDA levels in the SG rat kidney tissue and in RIR group were 3.6 ± 0.2 (P < 0.0001) and 7.6 ± 0.6 μmol/g protein, respectively. Total glutathione (tGSH) levels in TRIR, TPRIR, SG, and RIR animal groups were 2.2 ± 0.3 (P > 0.05), 5.8 ± 0.4 (P < 0.0001), 6.2 ± 0.2 (P < 0.0001), and 1.7 ± 0.2 nmol/g protein, respectively. In the TRIR, TPRIR, SG, and RIR animal groups; 8-hydroxyguanine (8-OHGua)/Gua levels, which indicate mutagenic DNA, were 1.75 ± 0.12 (P > 0.05), 0.93 ± 0.1 (P < 0.0001), 0.85 ± 0.08 (P < 0.0001), and 1.93 ± 0.24 pmol/L, respectively.Conclusions:It has been shown that thiamine pyrophosphate prevents increase in mutagenic DNA in IR induced oxidative damage, whereas thiamine does not have this effect.

Turistik ürün çeşitlendirmesi kapsamında birçok turizm türü bulunmaktadır. Kültür turizmi bu çeşitlilik kapsamında ilk sıralarda yer alan ve ikamesi olmayan bir turizm türüdür. Kültür turizmine katılan turistlerin temel motivasyon kaynağı ise kültürel değerler ve kültürel mirastır. Bu nedenle kültür turizminin temel çekiciliği olan kültürel değerlerin korunması ve sürdürülebilirliği büyük öneme sahiptir. Kültürel değerlere bu katkıyı yapacak olan kişilerden birisi de profesyonel turist rehberleridir. Turist rehberleri ülkelerinin kültür elçisi olmasının yanı sıra, turistlere aktardıkları kültürel değerlere karşı da sorumluluk taşımaktadır. Buradan hareketle gerçekleştirilen bu çalışmada profesyonel turist rehberinin kültürel değerlere ne şekilde katkısının olduğu belirlenmeye çalışılmıştır. Bu doğrultuda Kapadokya Bölgesi'ni ziyaret eden yerli ve yabancı 408 turiste anket uygulanmıştır. Araştırma kapsamında elde edilen veriler istatistiki yöntemlerle analiz edilmiştir. Yapılan bu analizler yardımıyla turist rehberinin kültürel değerlere nasıl katkı yaptığı ölçülmeye çalışılmıştır. Araştırma sonucunda bir kültür elçisi olarak profesyonel turist rehberinin kültürel değerlerin korunmasına, tanıtımına ve kültürler arası etkileşime katkı yaptığı bulgusuna ulaşılmıştır.
