Employee–customer identification: Effect on Chinese online shopping experience, trust, and loyalty

Abstract This study investigates Chinese consumers’ interaction with retail employees and the effects on shopping experience, trust, and loyalty. Survey data help articulate brand comparison, digital interactions, and shopping experience as customer-identification change agents. A structural equation model highlights how consumers’ perception of employee identification enhances shopping experience, builds consumer trust, and improves loyalty. The study displays how customer trust mediates the effect of employee identification and retailer adaptability on customer loyalty while digital interaction mediates the effect of brand comparison on customer trust. The theoretical implications of these findings emphasise the importance of consumer-employee interaction in the identification process where the relationships between brand comparison, digital interaction, and shopping experience are highlighted in a retail setting. These results denote that (a) store loyalty is predominantly driven by consumer self-consistence and social conformance and (b) retailer online and offline interaction and coordination influence brand experiences and consumer retention.
A New Upper-Level Circulation Index for the East Asian Summer Monsoon Variability

The East Asian summer monsoon (EASM) andits variability involvecirculationsystems in both the tropicsand midlatitudes as well as in both the lower and upper troposphere. Considering this fact, a new EASM index (NEWI) is proposed based on 200-hPa zonal wind, which takes into account wind anomalies in the southern (about 58N), middle (about 208N), and northern areas (about 358N) of East Asia. The NEWI can capture the interannual EASM-related climate anomalies and the interdecadal variability well. Compared to previous indices, theNEWIshowsabetterperformanceindescribingprecipitationandairtemperaturevariationsoverEastAsia.It can also show distinct climate anomalous features in early and late summer. The NEWI is tightly associated with the East Asian‐Pacific or the Pacific‐Japan teleconnection, suggesting a possible role of internal dynamics in the EASM variability. Meanwhile, the NEWI is significantly linked to El Nino‐Southern Oscillation and tropical Indian Ocean sea surface temperature anomalies. Furthermore, the NEWI is highly predictable in the ENSEMBLES models, indicating its advantage for operational prediction of the EASM. The physical mechanism of the EASM variability as represented by the NEWI is also explicit. Both warm advection anomalies of temperaturebyanomalouswesterlywindsandtheadvectionofanomalouspositiverelativevorticitybynortherly basic winds cause anomalous ascending motion over the mei-yu‐changma‐baiu rainfall area, and vice versa over the South China Sea area. Hence, this NEWI would be a good choice to study, monitor, and predict the EASM.
Self-esteem and general self-efficacy in an outdoor training program in university students

This study aimed to evaluate a program in which an outdoor training methodology was applied to develop self-efficacy and self-esteem. Specifically, the study aimed to determine the change in psychological variables, such as general self-efficacy and self-esteem, in a large sample of university students undertaking social sciences and participating in this program. A multivariate analysis was conducted on a group of 123 individuals to determine the composition of each variable and examine the moderating effect of the outdoor training program. Changes in the scores of these variables measured before and after implementing the program, in which different outdoor activities were carried out, are presented. The experiential training program positively affected general self-efficacy and self-esteem. Finally, the importance of this program, wherein an innovative outdoor training methodology has been applied to improve motivation, academic success, well-being, health, and adjustment of students in the university environment, is discussed.
Functional physical training improves fitness and cognitive development in 4~5 years old children

Background Development of physical and cognitive function is very critical in 4~5 years children. It has been addressed in this research if the 18 weeks of specific functional training with or without cognitive training can be effective on improving fitness and cognitive development in 4~5 years preschool children. Methods A total of 126 preschool children in the 4~5 age range were selected as participants and randomly assigned to one of four groups: the control group (C), the functional physical training group (P), the cognitive training group (CT), and the functional physical training combined with cognitive training group (PCT). Results The results revealed significant pre/post differences in body height and weight among all four groups of children. Furthermore, there was no significant difference in physical fitness between the C group and the CT group after the intervention. However, the children in the P group and the PCT group showed significant improvements in three indicators including standing long jump, continuous jump, and 10-meter shuttle running. Additionally, the children in P group, CT group, and the PCT group demonstrated significant improvement in simple reaction time, attention, and spatial memory. No significant cognitive improvement was found in C group. Conclusion Functional physical training with or without cognitive intervention can promote both physical fitness and cognitive development in children aged 4~5 years. Cognitive training alone can significantly improve cognitive function but not physical. Therefore, functional physical training can be used alone to improve the physical and cognitive abilities for aged 4~5 years old children.
A new 3D phase unwrapping method by region partitioning and local polynomial modeling in abdominal quantitative susceptibility mapping

Background Accurate phase unwrapping is a critical prerequisite for successful applications in phase-related MRI, including quantitative susceptibility mapping (QSM) and susceptibility weighted imaging. However, many existing 3D phase unwrapping algorithms face challenges in the presence of severe noise, rapidly changing phase, and open-end cutline. Methods In this study, we introduce a novel 3D phase unwrapping approach utilizing region partitioning and a local polynomial model. Initially, the method leverages phase partitioning to create initial regions. Noisy voxels connecting areas within these regions are excluded and grouped into residual voxels. The connected regions within the region of interest are then reidentified and categorized into blocks and residual voxels based on voxel count thresholds. Subsequently, the method sequentially performs inter-block and residual voxel phase unwrapping using the local polynomial model. The proposed method was evaluated on simulation and in vivo abdominal QSM data, and was compared with the classical Region-growing, Laplacian_based, Graph-cut, and PRELUDE methods. Results Simulation experiments, conducted under different signal-to-noise ratios and phase change levels, consistently demonstrate that the proposed method achieves accurate unwrapping results, with mean error ratios not exceeding 0.01%. In contrast, the error ratios of Region-growing (N/A, 84.47%), Laplacian_based (20.65%, N/A), Graph-cut (2.26%, 20.71%), and PRELUDE (4.28%, 10.33%) methods are all substantially higher than those of the proposed method. In vivo abdominal QSM experiments further confirm the effectiveness of the proposed method in unwrapping phase data and successfully reconstructing susceptibility maps, even in scenarios with significant noise, rapidly changing phase, and open-end cutline in a large field of view. Conclusion The proposed method demonstrates robust and accurate phase unwrapping capabilities, positioning it as a promising option for abdominal QSM applications.
Genetic Variability and Its Influence on the Fermentative Parameters of Kluyveromyces marxianus

ABSTRACT This research aimed to compare the genetic profile by karyotypes of strains of K. marxianus from different regions in México. K. marxianus karyotypes were analyzed by pulsed-field gel electrophoresis (PFGE-CHEF). The Cluster analysis was calculated by clustering the Pearson´s correlations matrix using the UPGMA algorithm, and mathematical models were used to describe some parameters that could not be determined analytically. K. marxianus strains showed 17 different chromosomal patterns divided into two Clusters. Cluster I only include the reference strain K. marxianus (CBS397). However, obtaining some karyotypes showed similar fermentative behaviours, while others had different fermentative behaviours. Therefore, it has been possible to differentiate a strain from different fermentation environments. The strains isolated from mezcal do not show significant differences except the strain with karyotype XII therefore obtaining information on the relationship between genetic and fermentative behaviour is a tool for strain selection for different technological applications.
Conformational Stability of the N-Terminal Region of MDM2

MDM2 is an E3 ubiquitin ligase which is crucial for the degradation and inhibition of the key tumor-suppressor protein p53. In this work, we explored the stability and the conformational features of the N-terminal region of MDM2 (N-MDM2), through which it binds to the p53 protein as well as other protein partners. The isolated domain possessed a native-like conformational stability in a narrow pH range (7.0 to 10.0), as shown by intrinsic and 8-anilinonapthalene-1-sulfonic acid (ANS) fluorescence, far-UV circular dichroism (CD), and size exclusion chromatography (SEC). Guanidinium chloride (GdmCl) denaturation followed by intrinsic and ANS fluorescence, far-UV CD and SEC at physiological pH, and differential scanning calorimetry (DSC) and thermo-fluorescence experiments showed that (i) the conformational stability of isolated N-MDM2 was very low; and (ii) unfolding occurred through the presence of several intermediates. The presence of a hierarchy in the unfolding intermediates was also evidenced through DSC and by simulating the unfolding process with the help of computational techniques based on constraint network analysis (CNA). We propose that the low stability of this protein is related to its inherent flexibility and its ability to interact with several molecular partners through different routes.
Hand Selection in Dribbling Phases: An Analysis of Non-Dominant Hand Usage and Dribble Change in Basketball

This study investigates the influence of different dribbling phases on hand selection among basketball players across various categories. A total of 33 guard players, including 11 from high school, college, and NBA teams each, were observed. Video data analysis was utilized to determine the frequency of players using their dominant hands (DHs) and non-dominant hands (NDHs) during in-game dribbling phases. The dribbling phases were classified into three categories: First (the initiation of the dribble), Middle (during the dribble but not in First and Last), and Last (the completion of the dribble). Percentage, means, and standard deviations were computed for each category within the First, Middle, and Last measurements. A two-factor analysis of variance (ANOVA) was conducted, considering player category and dribbling phase as factors. The ANOVA revealed significant main effects of player category (p < 0.01) and dribbling phase (p < 0.01). Post hoc multiple comparisons using Holm’s method indicated that, in the First phase, players exhibited a 6.5% higher preference for using their NDHs (43.4 ± 11.9%) compared to the Middle phase (36.9 ± 13.9%) (p < 0.05). Similarly, in the Last phase, players displayed a 5.3% greater inclination towards using their NDHs (42.2 ± 11.7%) compared to the Middle phase (p < 0.05). These findings provide quantitative evidence that the specific dribbling phase influences hand selection during gameplay. The implications of these results are significant for basketball coaches, as they can design targeted training programs and drills that simulate game scenarios and encourage NDH usage. By understanding the factors influencing hand choice, players can enhance their versatility and adaptability on the court. Furthermore, these findings contribute to player performance, skill development, and strategic decision making in dribbling phases.
Long-period, long-duration seismic events during hydraulic fracture stimulation of a shale gas reservoir

We report here a series of long-period and long-duration (LPLD) seismic events observed during hydraulic fracturing in a shale gas reservoir. These unusual events, 10–100 s in duration, are observed most clearly in the frequency band of 10–80 Hz and are remarkably similar in appearance to tectonic tremor sequences first observed in subduction zones. These complex but coherent wave trains have finite moveouts obtained from cross-correlation. The moveout direction of the events confirms that they originate in the reservoir from the area where the fracturing is going on. Clear P- and S-wave arrivals cannot be resolved within the LPLD episodes but, in some cases, small micro-earthquakes occur in the sequences. Whether these micro-earthquakes are causal or coincidental is not known. It has also been observed that in three contiguous frac-stages, all LPLD events appear to come from two distinct places along one of two hypothetical fracture planes. Interestingly, the stages which have the largest number of LPLD .
Floras from red beds of the Permian Basin of Lodève (Southern France)

Las plantas fosiles de las capas rojas de la cuenca de Lodeve son generalmente escasas y su estado de conservacion es relativamente pobre comparada a la flora del “Autuniense gris”. De acuerdo con los trabajos previos de Doubinger y tras una reevaluacion de las colecciones disponibles gracias a nuevos datos, son propuestas unas listas de las floras de las “capas rojas” de la “zona de transicion” de la Formacion de Rabejac y, por primera vez, de la Formacion de Salagou. Callipteris cf. uralensis y Supaia representan dos taxones significativos; el primero aparece en las capas rojas mientras que Supaia solamente es conocido en la Formacion de Rabejac. Este genero, previamente considerado endemico de Arizona, ha sido citado como presente en Rusia, Espana y China, ademas de la cuenca de Lodeve, en la que su presencia podria indicar una edad Artinskiana tardia a Kunguriana para esta seccion basal de lo que se conocia como “grupo Saxoniano”. Tambien es interesante el hecho de que algunas coniferas de Rabejac y de la Formacion de Salagou, mas reciente, muestran conos y/o hojas suculentas, similares a los de algunas coniferas Triasicas, lo que con toda certeza representa un cambio importante en la flora como respuesta a un clima progresivamente mas seco. Debido a las condiciones desfavorables de fosilizacion y teniendo en cuenta la importancia de la actividad animal en los ecosistemas de playa de la Formacion de Salagou, estas plantas poco frecuentes son interpretadas como los restos de una vegetacion originalmente mucho mas diversificada, posiblemente dominada por coniferas arborescentes.
A Novel Beam Channel Model for AIRS-Assisted Mobile-to-Mobile Communication Systems

Due to the existence of wind and pressure variation, the unmanned aerial vehicle (UAV) will undergo pitch and roll wobbles in 3-D space, which will further induce the position offset of the aerial intelligent reflector surface (AIRS) deployed on the UAV platform. In this article, we consider the impact of the UAV pitch and roll wobbles and the effective AIRS structure, which is the projected structure of AIRS reflection unit in the signal propagation direction, on the channel statistical characteristics, and propose a novel AIRS-assisted beam channel model for mobile-to-mobile (M-to-M) multiple-input–multiple-output (MIMO) communication systems. In the proposed model, the relationship between the scattering gain of the AIRS unit and its size is also considered. Based the proposed model, the power scaling law of the AIRS-assisted link is derived, and it is demonstrated that the average received signal power is proportional to the square of the total geometric area of the AIRS in the far-field region. The simulation results show that the UAV wobbles with small angles significantly affects the spatial correlation function and the average received signal power, and the Doppler spread can be significantly reduced by increasing the number of AIRS reflection units. The simulation results also show that the effective AIRS structure in the signal propagation direction is essential in AIRS-assisted channel modeling and the proposed AIRS-assisted M-to-M MIMO communication system can obtain higher performance gain than traditional M-to-M MIMO communication system.
Improved meteorology from an updated WRF/CMAQ modeling system with MODIS vegetation and albedo

Realistic vegetation characteristics and phenology from the Moderate Resolution Imaging Spectroradiometer (MODIS) products improve the simulation for the meteorology and air quality modeling system WRF/CMAQ (Weather Research and Forecasting model and Community Multiscale Air Quality model) that employs the Pleim‐Xiu land surface model (PX LSM). Recently, PX LSM WRF/CMAQ has been updated in vegetation, soil, and boundary layer processes resulting in improved 2 m temperature (T) and mixing ratio (Q), 10 m wind speed, and surface ozone simulations across the domain compared to the previous version for a period around August 2006. Yearlong meteorology simulations with the updated system demonstrate that MODIS input helps reduce bias of the 2 m Q estimation during the growing season from April to September. Improvements follow the green‐up in the southeast from April and move toward the west and north through August. From October to March, MODIS input does not have much influence on the system because vegetation is not as active. The greatest effects of MODIS input include more accurate phenology, better representation of leaf area index (LAI) for various forest ecosystems and agricultural areas, and realistically sparse vegetation coverage in the western drylands. Despite the improved meteorology, MODIS input causes higher bias for the surface O3 simulation in April, August, and October in areas where MODIS LAI is much less than the base LAI. Thus, improvements may be needed in the CMAQ dry deposition model for low LAI areas where deposition on the soil surface becomes important.
Middle Devonian volcanism in eastern Heilongjiang Province and its tectonic implications: constraints from petro-geochemistry,zircon U-Pb chronology and Sr-Nd-Hf isotopes

This paper has reported zircon U-Pb dating,Hf isotopes,major and trace elements,and Sr-Nd isotope data of the volcanic rocks from the Laotudingzi Formation in the eastern margin of the Jiamusi Massif and the upper segment of the Baoquan Formation in the Xiao Hinggan Mountains,with the aim of constraining the regional tectonic evolution in eastern Heilongjiang Province.The former is composed mainly of rhyolite and subordinately of alkaline basalt,whereas the latter consists chiefly of rhyolite.Zircons from these volcanic rocks display striped absorption or fine-scale oscillatory growth zoning as well as high Th/U ratios(0.28~1.64),implying a magmatic origin.The dating results show that they were probably all formed in middle Devonian(a weighted mean 206Pb/238U age of 386 Ma). The mafic rocks from the Laotudingzi Formation in the eastern margin of the Jiamusi Massif have the data SiO2=50.40%~55.66%,Mg#=0.39~0.50,Na2O/K2O=2.88~4.99,Al2O3=15.66%~18.06%,(87Sr/86Sr)i=0.705 99,eNd(t)=+2.04,and show the enrichment of light rare earth elements(LREEs) and Cr,Co,Ni and Zr,and depletion of Nb,Ta,Ti,with high Zr/Y,Nb/U,Ta/U and Ce/Pb ratios,whereas the felsic rocks have the data SiO2=77.59%~78.75%,Na2O/K2O=0.32~0.36,Al2O3=11.62%~11.76%,(87Sr/86Sr)i=0.703 78~0.707 36,eNd(t)=-2.20~-4.15,eHf(t)=+1.8~+8.6,tDM1= 671~998 Ma,and display enrichment of Rb,Th,U,K and depletion of Nb,Ta,U,P,Ti.These data are typical of bimodal volcanism and indicate that the former might have been derived from the lithosphere mantle,contaminated by crustal material,whereas the latter probably originated from partial melting of the newly accreted crust.The rhyolite from the upper Baoquan Formation in the Xiao Hinggan Mountains is characterized by high SiO2(74.64%~76.09%),enrichment of K2O(Na2O/K2O=0.42~0.81),low Al2O3(12.56%~12.63%),enrichment of high field strength elements(such as Zr and Hf)and large ion lithophile elements(LILEs)such as Th,U and K,and strong depletion of Sr,Eu,P and Ti.These data are similar to features of A-type rhyolites.Besides,these volcanic rocks have eHf(t)=+2.5~+6.4,tDM1= 837~983 Ma,consistent with the data of Phanerozoic granitoids in the CAOB,suggesting that they might have originated from partial melting of the newly accreted crust.Combined with the regional geological data,it is inferred that there might have existed a passive continental-margin setting in the eastern margin of the Jiamusi Massif in middle Devonian,where the bimodal volcanic rocks were probably formed.Furthermore,the coeval A-type rhyolite of the upper Baoquan Formation in the Xiao Hinggan Mountains was probably formed in an intra-continental extensional environment.
Gravity and magnetic modelling of southern Northland Basin, New Zealand

Summary A combined interpretation of gravity, magnetic and seismic data has been used to investigate some key structural elements of the southern part of the Northland Basin which lies off the west coast of North Island, New Zealand. 2-D seismic reflection data reveal a thick sedimentary sequence, a number of significant structural highs and large Miocene volcanic complexes. The basement reflector is generally poorly imaged, especially below locations where volcanics are evident at shallower levels in the seismic sections. Gravity and magnetic maps clearly show the locations of the major volcanic centres which have strong anomalies (up to 50 mGal and 800 nT). In addition, a belt of positive magnetic anomalies (up to ~200 nT) trends N-S in the south and NW-SE in the north. This follows the strike of the main structural trends in the region and suggests the occurrence of a highly magnetic basement terrane. Preliminary 2.75D gravity and magnetic modelling shows that the Miocene volcanic bodies are broader than previously interpreted and extend to basement depths. Modelling also shows that the top of the basement is deeper (up to 9 km) than is evident in the seismic sections. The gravity and magnetic data therefore are invaluable in resolving some of the ambiguities in the seismic interpretation.
Extensional and compressional zones in slumps and slides in the Namurian of County Clare, Ireland

Extensional and compressional zones in slumps and slides have been studied in a well-exposed Namurian (Carboniferous) base-of-slope and delta slope sedimentary succession in County Clare, Ireland. Extensional zones are in slumps dominantly characterized by single, downslope-dipping normal faults, while in slides they are characterized by normal, listric fault families. These faults sometimes show minor growth. Compressional zones in slumps are dominated by a single reverse fault with upslope-dip. They are only rarely characterized by imbricate fault fans. Compressional zones in slides fall into a tri-partite division of thick packages, thin packages and basal zones. Thick packages compare with tectonic imbricate zones, while thin packages are simpler and characterized by very shallow synthetic thrusts. Basal zones compare with blind imbricate fans. Lateral margins of both extensional and compressional zones in slumps and slides show transfer faults with transtensional, transpressional or purely strike-slip motion, depending on the width variability of the slide and slump scars. The similarity in structural style between soft-sediment deformational structures and deformation structures in lithified rocks shows that, on the basis of structural style alone, it is problematical to differentiate between these two groups of structures.
