Recover From Failure: Examining the Impact of Service Recovery Stages on Relationship Marketing Strategies
Purpose: Given the digital transformation of service businesses by providing online food services and the influence of online reviews on consumers’ purchasing decisions, this study examines how service recovery attributes in different stages influence relationship marketing strategies, i.e., relationship quality and customer loyalty after service failure. This study is built upon a revised service recovery cycle model by accounting for three stages and their corresponding attributes; whereon a conceptual stage model of service recovery is proposed. This conceptual stage model incorporates stages of service recovery, their respective attributes, and how they influence relationship marketing strategies. Design/methodology/approach: An online marketing company was employed for data collection in 2019, which resulted in 301 valid responses. A Structural Equation Model (SEM) was conducted with all the data to test the relationships between the constructs. The individual measurement model was tested using the Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA). A structural model was estimated using AMOS to test all the hypotheses. Findings: The findings demonstrate that the attributes (i.e., response speed, compensation) paired with the first two stages of service recovery can significantly influence consumer loyalty in a positive state. The findings also manifest the intermediary role that relationship quality has played in the association of service recovery and consumer loyalty, which implies that the food delivery businesses could attain a more comprehended relationship quality with consumers through active and timely compensatory service recovery consumer loyalty to the food businesses. Originality/value: This study examines how these different stages of the service recovery cycle influence the decision-making of relationship marketing strategies (i.e., relationship quality, customer loyalty) on the prerequisite of service failure. This study aspires to expand the service recovery research by objectifying a conceptual stage model of service recovery, incorporating stages’ recovery attributes and how these recovery attributes reciprocally influence relationship quality and customer loyalty
Exact Results for the Residual Entropy of Ice Hexagonal Monolayer
Since the problem of the residual entropy of square ice was exactly solved,
exact solutions for two-dimensional realistic ice models have been of interest.
In this paper, we study the exact residual entropy of ice hexagonal monolayer
in two cases. In the case that the external electric field along the z-axis
exists, we map the hydrogen configurations into the spin configurations of the
Ising model on the Kagom\'e lattice. By taking the low temperature limit of the
Ising model, we derive the exact residual entropy, which agrees with the result
determined previously from the dimer model on the honeycomb lattice. In another
case that the ice hexagonal monolayer is under the periodic boundary conditions
in the cubic ice lattice, we employ the six-vertex model on the square lattice
to represent the hydrogen configurations obeying the ice rules. The exact
residual entropy in this case is obtained from the solution of the equivalent
six-vertex model. Our work provides more examples of the exactly soluble
two-dimensional models.Comment: 26 pages, 5 figure
Dimethyl 1-(2-cyanobenzyl)-1H-pyrazole-3,5-dicarboxylate
In the molecule of the title compound, C15H13N3O4, the dihedral angle between the pyrazole and benzene rings is 79.89 (6)°. An intramolecular C—H⋯O hydrogen bond is present. The crystal structure is stabilized by π–π stacking interactions between centrosymmetrically related pyrazole rings with a centroid–centroid distance of 3.500 (3) Å
Mental imagery and acute exercise on episodic memory function
© 2019 by the authors. Licensee MDPI, Basel, Switzerland. Mental imagery is used extensively in the sporting domain. It is used for performance-enhancement purposes, arousal regulation, affective and cognitive modification, and rehabilitation purposes. The purpose of this experiment was to evaluate whether acute exercise and mental imagery of acute exercise have similar effects on cognitive performance, specifically memory function. A within-subject randomized controlled experiment was employed. Participants (N = 24; Mage = 21.5 years) completed two exercise-related visits (i.e., actual exercise and mental imagery of exercise), in a counterbalanced order. The acute-exercise session involved 10 min of intermittent sprints. The mental-imagery session involved a time-matched period of mental imagery. After each manipulation (i.e., acute exercise or mental imagery of acute exercise), memory was evaluated from a paired-associative learning task and a comprehensive evaluation of memory, involving spatial–temporal integration (i.e., what, where, and when aspects of memory). Bayesian analyses were computed to evaluate the effects of actual exercise and mental imagery of exercise on memory function. For the paired-associative learning task, there was moderate evidence in favor of the null hypothesis for a main effect for condition (BF01 = 2.85) and time by condition interaction (BF01 = 3.30). Similarly, there was moderate evidence in favor of the null hypothesis for overall (what-where-when) memory integration (BF01 = 3.37), what-loop (BF01 = 2.34), where-loop (BF01 = 3.45), and when-loop (BF01 = 3.46). This experiment provides moderate evidence in support of the null hypothesis. That is, there was moderate evidence to support a non-differential effect of acute exercise and mental imagery of acute exercise on memory function
LncRNA-p21 alters the antiandrogen enzalutamide-induced prostate cancer neuroendocrine differentiation via modulating the EZH2/STAT3 signaling
While the antiandrogen enzalutamide (Enz) extends the castration resistant prostate cancer (CRPC) patients' survival an extra 4.8 months, it might also result in some adverse effects via inducing the neuroendocrine differentiation (NED). Here we found that lncRNA-p21 is highly expressed in the NEPC patients derived xenograft tissues (NEPC-PDX). Results from cell lines and human clinical sample surveys also revealed that lncRNA-p21 expression is up-regulated in NEPC and Enz treatment could increase the lncRNA-p21 to induce the NED. Mechanism dissection revealed that Enz could promote the lncRNA-p21 transcription via altering the androgen receptor (AR) binding to different androgen-response-elements, which switch the EZH2 function from histone-methyltransferase to non-histone methyltransferase, consequently methylating the STAT3 to promote the NED. Preclinical studies using the PDX mouse model proved that EZH2 inhibitor could block the Enz-induced NED. Together, these results suggest targeting the Enz/AR/lncRNA-p21/EZH2/STAT3 signaling may help urologists to develop a treatment for better suppression of the human CRPC progression
Large intrinsic anomalous Hall effect in both NbFeB and TaFeB with collinear antiferromagnetism
It is rarely reported that collinear antiferromagnetic (AFM) metals can have
anomalous Hall effect (AHE). In this letter, based on symmetry analysis and the
first-principles electronic structure calculations, we predict that two
existing collinear antiferromagnets NbFeB and TaFeB,
whose N\'eel temperatures are above room temperature, have very large AHE with
anomalous Hall conductance (AHC) -100 cm and
cm, respectively. We further complete the symmetry
resquirements for realizing the AHE in collinear antiferromagnetism
Geometry-Experiment Algorithm for Steiner Minimal Tree Problem
It is well known that the Steiner minimal tree problem is one of the classical nonlinear combinatorial optimization problems. A visualization experiment approach succeeds in generating Steiner points automatically and showing the system shortest path, named Steiner minimum tree, physically and intuitively. However, it is difficult to form stabilized system shortest path when the number of given points is increased and irregularly distributed. Two algorithms, geometry algorithm and geometry-experiment algorithm (GEA), are constructed to solve system shortest path using the property of Delaunay diagram and basic philosophy of Geo-Steiner algorithm and matching up with the visualization experiment approach (VEA) when the given points increase. The approximate optimizing results are received by GEA and VEA for two examples. The validity of GEA was proved by solving practical problems in engineering, experiment, and comparative analysis. And the global shortest path can be obtained by GEA successfully with several actual calculations
