Purpose -Drawing on consumer behavior and service marketing literature, the aim of this paper is to empirically examine how customers' justice judgment and consumption emotions affect customer relationships and their post consumption behaviors in a service recovery context. Design/methodology/approach -Structural equation modeling (SEM) was adopted to test the conceptual model, using a sample of nearly 600 delayed airline passengers. Findings -Perceived justice and consumption emotions are important elements affecting customers' evaluation of service recovery. The three dimensions of service recovery justice and customers' positive and negative emotions have direct or indirect influence on customers' satisfaction with service recovery (SSR), customer trust, and their repurchase intentions and word-of-mouth recommendations. Theoretical and managerial implications were drawn based on the findings. Originality/value -The current study sought to extend the existing literature by not only analyzing the effects of perceived justice and consumption emotions on satisfaction with service recovery (SSR), but also investigating how customer SSR would influence their sense of trust for the company and their behavioral intentions. In addition, many prior studies adopted experimental methods and post survey methods. Those methods have various validity problems. This study attempted to overcome those problems by using on-the-spot investigation methods to study customers' evaluation of service recovery in real service failure situations.

Currently, several single extraction methods are used for the evaluation of the phytoavailability of metals using pot experiments. A systematic comparison, however, is lacking. It is especially true for the field studies. This study was to investigate the phytoavailability of trace elements to vegetables grown on metal-contaminated soils under the field conditions. All soils collected were typical calcareous soils in northern China. Four frequently used methods using CaCl 2 , diethylenetriaminepentaacetic acid (DTPA), CH 3 COOH, and water as extractants were compared for phytoavailability. The concentrations of metals extracted by these four extraction methods ranged from 3.42 to 815, 1.51-6965, 0.732-24 473, 0.688-7863, 0.246-685, 1.99-5337 0.203-4649 ng/g for Cr, Ni, Zn, Cu, Cd, Pb and REEs, respectively. Simple correlation analysis indicated that a significant correlation (Cr: r ¼ 0:5411 ÃÃ ; Zn: r ¼ 0:6352 ÃÃ ; Cd: r ¼ 0:6979 ÃÃ ; Pb: r ¼ 0:5537 ÃÃ and REEs: r ¼ 0:5185 ÃÃ -0:6684 ÃÃ ) was observed between the CaCl 2 -extractable metals in soil solution and that in Chinese cabbage. In addition, soil pH, organic matter (OM), and cation exchange capacity (CEC) also affect the phytoavailability. An empirical model was developed to express the combined effect of soil properties on the phytoavailability. The stepwise multiple regression analysis demonstrated that the phytoavailability of trace elements strongly correlated with the extractable fraction by CaCl 2 , total metal concentration in soils, and soil pH, OM, CEC. This model can describe approximately 75-95% of the variability of metal uptake and the r 2 values ranged from 0.741 ÃÃ to 0.954 ÃÃ , which were much better than the single correlation analysis. For celery and cole, a strong correlation was obtained for Cr, Ni, Zn, Cu, Cd, La, Ce, Pr and Nd. For spinach and Chinese cabbage, however, a positive correlation was only observed for 1 and 3 metals, respectively. Generally, the developed empirical model can integrate the combined effects of soil properties, extractable metal fractions in soil solutions and plant species on the phytoavailability of metals to vegetables in the field conditions.

Rex rabbit is an important small herbivore for fur and meat production. However, little is known about the gut microbiota in rex rabbit, especially regarding their relationship with different fecal types and growth of the hosts. We characterized the microbiota of both hard and soft feces from rex rabbits with high and low body weight by using the Illumina MiSeq platform targeting the V4 region of the 16S rDNA. High weight rex rabbits possess distinctive microbiota in hard feces, but not in soft feces, from the low weight group. We detected the overrepresentation of several genera such as YS2/Cyanobacteria, and Bacteroidales and underrepresentation of genera such as Anaeroplasma spp. and Clostridiaceae in high weight hard feces. Between fecal types, several bacterial taxa such as Ruminococcaceae, and Akkermansia spp. were enriched in soft feces. PICRUSt analysis revealed that metabolic pathways such as “stilbenoid, diarylheptanoid, gingerol biosynthesis” were enriched in high weight rabbits, and pathways related to “xenobiotics biodegradation” and “various types of N-glycan biosynthesis” were overrepresented in rabbit soft feces. Our study provides foundation to generate hypothesis aiming to test the roles that different bacterial taxa play in the growth and caecotrophy of rex rabbits.

Background and aims Perfluorinated compounds (PFCs) are of particular environmental concern. The migration of PFCs from soil to plants is a likely pathway for PFCs to enter the human food chain. This study aimed to investigate the uptake mechanisms of perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) by maize (Zea mays L. cv. TY2).Methods Hydroponic greenhouse experiments were performed. Results The kinetics of PFOS and PFOA uptake fitted Mechaelis-Menten equation well, suggesting their carrier-mediated influx processes. Uptake of PFOS was insensitive to metabolic inhibitors (NaN 3 and Na 3 VO 4 ). In contrast, treated with NaN 3 and Na 3 VO 4 reduced the uptake of PFOA by 83 and 43 % respectively. PFOS uptake was decreased by 31 % and 25 % when plants were treated with aquaporin inhibitors, AgNO 3 and glycerol, respectively, while aquaporin inhibitors had no effect on PFOA uptake. Anion channel blockers, 4, 4′-diisothiocyanostibene-2,2′-disolfonate (DID) and 5-nitro 2-(3-phenylpropylamine) benzoic acid (NPPB) inhibited the uptake of PFOS by 33 % and 30 %, respectively. Anion channel blocker anthracene-9-carboxylic acid (9-AC) decreased the uptake of PFOA by 28 %. No competitive uptake was found between PFOS and PFOA. Conclusions Uptake of PFOS and PFOA by maize may have different mechanisms.
