The intellectual structure of customer experience research in service scholarship: a bibliometric analysis

ABSTRACT This study presents a framework and viewpoint on the intellectual structure and evolution of customer experience research in the service literature. Using the Scopus database, journal articles on customer experience have been extracted and examined to unearth the source knowledge and main themes via a two-step approach of bibliometric (citation and co-citation) and content analyses. The bibliometric analysis has revealed five main clusters of the knowledge domain: (1) methodology and information technology, (2) customer co-creation of value, (3) service quality and customer satisfaction, (4) tourist experience, (5) customer perception in service environments. Based on the literature review, content analysis was subsequently performed to reveal recent articles from each cluster. Overall, this article comprehensively examines customer experience literature in the service industries. Results present a holistic comprehension of the knowledge domain, reveal scientific progress, and provide main directions and questions for further academic efforts.

Auditing the Representation of Female Versus Male Athletes in Sports Science and Sports Medicine Research: Evidence-Based Performance Supplements

Although sports nutrition guidelines promote evidence-based practice, it is unclear whether women have been adequately included in the underpinning research. In view of the high usage rates of performance supplements by female athletes, we conducted a standardised audit of the literature supporting evidence-based products: β-alanine, caffeine, creatine, glycerol, nitrate/beetroot juice and sodium bicarbonate. Within 1826 studies totalling 34,889 participants, just 23% of participants were women, although 34% of studies included at least one woman. Across different supplements, 0–8% of studies investigated women exclusively, while fewer (0–2%) were specifically designed to compare sex-based responses. The annual publication of female-specific studies was ~8 times fewer than those investigating exclusively male cohorts. Interestingly, 15% of the female participants were classified as international/world-class athletes, compared with 7% of men. Most studies investigated performance outcomes but displayed poorer representation of women (16% of participants), whereas health-focussed studies had the greatest proportion of female participants (35%). Only 14% of studies including women attempted to define menstrual status, with only three studies (~0.5%) implementing best practice methodologies to assess menstrual status. New research should target the efficacy of performance supplements in female athletes, and future sports nutrition recommendations should specifically consider how well female athletes have contributed to the evidence-base.
A Model for Assessment of Organizational Culture Based on a Mixed Approach (Case Study: Kurdistan Provincial government)

The study aim is suggesting an appropriate model for identification and measurement of organizational culture in Kurdistan Provincial government. The research method is a combination of an exploratory sequential design which is at the first level qualitative and then at the second level goes quantitative. The final model at the first level was comprised of 5 dimensions, 14 components and 54 indicators. For modeling, the semi-structured interviews were conducted with experts in the organization where using Fuzzy Delphi Technique the qualitative validation performed. In gathering the data a researcher-made questionnaire at the second level (quantitative) was applied. For quantitative model validation, the first and second order Confirmatory Factor Analysis and Structural Equation Modeling were used. The results indicate that all organizational culture model coefficients in Kurdistan state-government office were significant and acceptable with a confidence level more than 99%.
Mental Health‐Related Emergency Department Visits Among Children During The Early COVID‐19 Pandemic

Objective To measure univariate and covariate‐adjusted trends in children's mental health‐related emergency department (MH‐ED) use across geographically diverse areas of the U.S. during the first wave of the Coronavirus‐2019 (COVID‐19) pandemic. Method This is a retrospective, cross‐sectional cohort study using electronic health records from four academic health systems, comparing percent volume change and adjusted risk of child MH‐ED visits among children aged 3–17 years, matched on 36‐week (3/18/19–11/25/19 vs. 3/16/20–11/22/20) and 12‐week seasonal time intervals. Adjusted incidence rate ratios (IRR) were calculated using multivariate Poisson regression. Results Visits declined during spring‐fall 2020 (n = 3892 vs. n = 5228, −25.5%) and during spring (n = 1051 vs. n = 1839, −42.8%), summer (n = 1430 vs. n = 1469, −2.6%), and fall (n = 1411 vs. n = 1920, −26.5%), compared with 2019. There were greater declines among males (28.2% vs. females −22.9%), children 6–12‐year (−28.6% vs. −25.9% for 3–5 years and −22.9% for 13–17 years), and Black children (−34.8% vs. −17.7% to −24.9%). Visits also declined for developmental disorders (−17.0%) and childhood‐onset disorders (e.g., attention deficit and hyperactivity disorders; −18.0%). During summer‐fall 2020, suicide‐related visits rose (summer +29.8%, fall +20.4%), but were not significantly elevated from 2019 when controlling for demographic shifts. In contrast, MH‐ED use during spring‐fall 2020 was significantly reduced for intellectual disabilities (IRR 0.62 [95% CI 0.47–0.86]), developmental disorders (IRR 0.71 [0.54–0.92]), and childhood‐onset disorders (IRR 0.74 [0.56–0.97]). Conclusions The early pandemic brought overall declines in child MH‐ED use alongside co‐occurring demographic and diagnostic shifts. Children vulnerable to missed detection during instructional disruptions experienced disproportionate declines, suggesting need for future longitudinal research in this population.
Increasing Farmers’ Access to Aquaculture Extension Services: Lessons from Central and Northern Uganda

This paper focuses on examining the modalities of extension service provision, and determining feasible approaches for increasing accessibility among fish farmers in Uganda. The paper draws on a cross-sectional study involving fish farming households and extension workers to determine access to extension services for improved farming practices. Quantitative data were collected from 246 households using a semi-structured questionnaire. Qualitative data were generated from Key Informant interviews with selected extension workers, officials in charge of extension planning District Fisheries Officers and Fish Farmer Group leaders. Focus Group Discussions were also conducted with fish farmers. The results indicated a significant association between socio-economic characteristics of fish farmers and access to extension services. Size of land owned, income from pond fish and membership to fish-farmer groups were the significant factors (P<0.05). All the respondents reported pressing needs which required extension intervention. The respondents expressed the need to form effective farmer groups for the purpose of sharing knowledge, arriving at mutual agreement on scheduling extension activities and providing feedback to the extension workers. Specifically for the northern region, there is a need for the Fisheries Extension Officer to identify and respond to the extension needs of fish farmers through various means including ICTs. Identifying solutions to social, technical and institutional constraints in extension can increase access to services through constructive social interactions between farmers and extension agents. The article provides important lessons for practice and policy, and proposes a farmer-centred model, capable of facilitating increased access to aquaculture extension services in Uganda.
Crystal structures of lanthanide terephthalate tetrahydrate, R2(C8H4O4)3(H2O)4, R = La–Er

The crystal structures of 11 lanthanide terephthalate tetrahydrates have been refined using laboratory X-ray powder diffraction data and optimized using density functional techniques. The lattice parameters and R–O bonds exhibit expected trends based on the cation size. The R–O bond distances in the Rietveld-refined structures are similar. However, in the density functional theory (DFT)-optimized structures, the bond distances break into two distinct groups, longer and shorter R–O bonds. This indicates that the bond distance restraints imposed upon the refined structures may have a greater impact than is expected from their weights. The aromatic carboxyl groups were not completely planar, but it is known that the carboxyl groups can rotate to accommodate hydrogen bonding and coordination to the metal. Both water molecules coordinated to the lanthanides act as hydrogen bond donors, but only one of the three unique carboxyl groups acts as an acceptor.
Radiation Hard 3D Diamond Sensors for Vertex Detectors at HL-LHC

Diamond is a good candidate to replace silicon as sensor material in the innermost layer of a tracking detector at HL-LHC, due to its high radiation tolerance. After particle fluences of $10^{16}\,{\rm protons/cm^2}$, diamond sensors are expected to achieve a higher signal to noise ratio than silicon. In order to use low grade polycrystalline diamonds as sensors, electrodes inside the diamond bulk, so called 3D electrodes, are produced. Typically, this kind of diamond material has a lower charge collection distance (CCD) than higher grade diamond, which results in a decreased signal amplitude. With 3D electrodes it is possible to achieve full charge collection even in samples with low CCDs by decoupling the spacing of the electrodes from the thickness of the diamond bulk. The electrodes are produced using a femtosecond laser, which changes the phase of the diamond material. The phase changed material is conductive and identified as nanocrystalline graphite using Raman spectroscopy. Due to a crater like structure of the channels on one side of the diamond, contacting of the channels is difficult. With the femtosecond laser setup conductive channels are produced at a laser power of $150\,{\rm mW}$ and a velocity of the diamond sample of $2$ - $10\,{\rm mm/s}$.
Privacy Notifications for Transparency in Fitness Apps

mHealth applications including fitness apps are an important trend. To monitor fitness activities a broad range of personal data is processed typically including location data and vital signs. For some of these applications it is not transparent which data is processed. To foster transparency and intervenability in mobile applications the concept of privacy notifications is an opportunity to provide users with information about processed data during the use of the application. In the context of a fitness app a concept for privacy notifications is proposed and evaluated in a user study.
Presidential policy narratives and the (mis)use of scientific expertise: Covid-19 policy responses in Brazil, Colombia, and Mexico

ABSTRACT Political leaders rely on narratives to make sense of crises, but the extent to which such narratives are used to (de)mobilize scientific evidence in policy responses has not been fully explored. Based on the analysis of public messages and communications of the presidents of Brazil, Colombia, and Mexico, we discuss how they have narratively approached the Covid-19 crisis, particularly with respect to the degree of their reliance on scientific expertise. Building on debates on policy narratives, crisis management, and evidence-based policymaking, we argue that the narratives presidents devised had significant (and mostly negative) effects on the design of policy responses. Their narratives sidelined (Bolsonaro), leveraged (Duque), or limited (López-Obrador) the role of scientific expertise in policy responses. Thus, in contrast to previous literature, these narratives aligned more with the president’s agendas and personal biases, than with the need to explain the crisis for their societies or to design appropriate policies.
Fixed-Bed Adsorption of Lead from Aqueous Solution Using Chitosan-Coated Bentonite

In this study, fixed-bed adsorption of Pb(II) from an aqueous solution using chitosan-coated bentonite (CCB) was investigated. Characterization of CCB was performed using Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). The effects of varying bed height (1.3 to 4.3 cm), flow rate (0.20 to 0.60 mL/min), and initial concentration (500 to 1500 mg/L) on the length of mass transfer zone (Zm) and adsorption capacity at breakthrough (qb) and exhaustion (qe) were examined. Low flow rate and high bed height were determined to cause a longer time to reach breakthrough and exhaustion. Meanwhile, the fixed-bed system was observed to quickly attain breakthrough and exhaustion under high initial concentrations. Kinetic column models such as the Thomas, Yoon–Nelson, and Clark models were used to predict the breakthrough curves. High R2 values (0.9758 ≤ R2 ≤ 0.8087) were attained for the Thomas model, which indicates that there is good agreement between experimental data and linear plots generated by the Thomas model. Moreover, the Thomas model is best in describing the breakthrough curves of Pb(II) removal under a fixed-bed system.
Postexercise hypotension and heart rate variability response after water- and land-based high-intensity interval exercise in prehypertensive obese men

A randomized crossover trial was carried out in prehypertensive obese men to compare postexercise hypotension and heart rate variability (HRV) following water-based and land-based high-intensity interval exercises (HIIEs). Nine prehypertensive obese participants, aged 23.6± 2.4 years, were randomly assigned to one of three interventions: no-exercise control, HIIE with immersion up to the chest, or HIIE on dry land. In the evenings of three separate days, participants performed either of the interventions. Matched with exercise volume, both HIIEs composed of 5 repetitions of 30-sec sprints at maximum effort followed by a 4-min rest. Ambulatory blood pressure and HRV were measured before the interventions and over the 24-hr following period. Both HIIEs resulted in significant reductions of average 24-hr mean arterial pressure (−6.7 mmHg). Notably, the water-based HIIE resulted in a significantly higher reduction of 24-hr systolic blood pressure (SBP) (−9 mmHg) than the land-based HIIE, particularly at night, in addition to a significantly longer duration of postexercise hypotension. Finally, the water-based HIIE was more effective at restoring HRV during recovery. Our findings demonstrated postexercise hypotension following the HIIEs, particularly the water-based HIIE. During recovery, the water-based HIIE was remarkably effective at restoring HRV. These findings indicate that water-based HIIE is more effective at reducing SBP and requires less recovery time than land-based HIIE in prehypertensive obese men.
Targeting Apoptosis Pathways With BCL2 and MDM2 Inhibitors in Adult B-cell Acute Lymphoblastic Leukemia

In adult patients, the treatment outcome of acute lymphoblastic leukemia (ALL) remains suboptimal. Here, we used an ex vivo drug testing platform and comprehensive molecular profiling to discover new drug candidates for B-ALL. We analyzed sensitivity of 18 primary B-ALL adult patient samples to 64 drugs in a physiological concentration range. Whole-transcriptome sequencing and publicly available expression data were used to examine gene expression biomarkers for observed drug responses. Apoptotic modulators targeting BCL2 and MDM2 were highly effective. Philadelphia chromosome–negative (Ph–) samples were sensitive to both BCL2/BCL-W/BCL-XL-targeting agent navitoclax and BCL2-selective venetoclax, whereas Ph-positive (Ph+) samples were more sensitive to navitoclax. Expression of BCL2 was downregulated and BCL-W and BCL-XL upregulated in Ph+ ALL compared with Ph– samples, providing elucidation for the observed difference in drug responses. A majority of the samples were sensitive to MDM2 inhibitor idasanutlin. The regulatory protein MDM2 suppresses the function of tumor suppressor p53, leading to impaired apoptosis. In B-ALL, the expression of MDM2 was increased compared with other hematological malignancies. In B-ALL cell lines, a combination of BCL2 and MDM2 inhibitor was synergistic. In summary, antiapoptotic proteins including BCL2 and MDM2 comprise promising targets for future drug studies in B-ALL.
Structural and Kinetic Views of Molecular Chaperones in Multidomain Protein Folding

Despite recent developments in protein structure prediction, the process of the structure formation, folding, remains poorly understood. Notably, folding of multidomain proteins, which involves multiple steps of segmental folding, is one of the biggest questions in protein science. Multidomain protein folding often requires the assistance of molecular chaperones. Molecular chaperones promote or delay the folding of the client protein, but the detailed mechanisms are still unclear. This review summarizes the findings of biophysical and structural studies on the mechanism of multidomain protein folding mediated by molecular chaperones and explains how molecular chaperones recognize the client proteins and alter their folding properties. Furthermore, we introduce several recent studies that describe the concept of kinetics–activity relationships to explain the mechanism of functional diversity of molecular chaperones.
Variscan structures and their control on latest to post-Variscan basin architecture: insights from the westernmost Bohemian Massif and southeastern Germany

Abstract. The Bohemian Massif exposes structures and metamorphic rocks remnant from the Variscan orogeny in central Europe and is bordered by the Franconian Fault System (FFS) to the west. Across the FFS, Variscan units and structures are buried by Permo-Mesozoic sedimentary rocks. We integrate existing DEKORP 2D seismic reflection, well, and surface geological data with the newly acquired FRANKEN 2D seismic survey to investigate the possible westward continuation of Variscan tectonostratigraphic units and structures and their influence on latest to post-Variscan basin development. Subsurface Permo-Mesozoic stratigraphy is obtained from available wells and tied to seismic reflection profiles using a synthetic seismogram calculated from density and velocity logs. Below the sedimentary cover, three main basement units are identified using seismic facies descriptions that are compared with seismic reflection characteristics of exposed Variscan units east of the FFS. Our results show upper Paleozoic low-grade metasedimentary rocks and possible Variscan nappes bounded and transported by Variscan shear zones ca. 65 km west of the FFS. Basement seismic facies in the footwall of the Variscan shear zones are interpreted as Cadomian basement and overlaying Paleozoic sequences. We show that the location of normal fault-bounded latest to post-Variscan late Carboniferous–Permian basins are controlled by the geometry of underlying Variscan shear zones. Some of these late Carboniferous–Permian normal faults reactivated as steep reverse faults during the regional Upper Cretaceous inversion. Our results also highlight that reverse reactivation of normal faults gradually decreases west of the FFS.
The Phosphorus Bond, or the Phosphorus-Centered Pnictogen Bond: The Covalently Bound Phosphorus Atom in Molecular Entities and Crystals as a Pnictogen Bond Donor

The phosphorus bond in chemical systems, which is an inter- or intramolecular noncovalent interaction, occurs when there is evidence of a net attractive interaction between an electrophilic region associated with a covalently or coordinately bonded phosphorus atom in a molecular entity and a nucleophile in another, or the same, molecular entity. It is the second member of the family of pnictogen bonds, formed by the second member of the pnictogen family of the periodic table. In this overview, we provide the reader with a snapshot of the nature, and possible occurrences, of phosphorus-centered pnictogen bonding in illustrative chemical crystal systems drawn from the ICSD (Inorganic Crystal Structure Database) and CSD (Cambridge Structural Database) databases, some of which date back to the latter part of the last century. The illustrative systems discussed are expected to assist as a guide to researchers in rationalizing phosphorus-centered pnictogen bonding in the rational design of molecular complexes, crystals, and materials and their subsequent characterization.
Bacterial Coinfection and Antibiotic Resistance Profiles among Hospitalised COVID-19 Patients

While it is reported that COVID-19 patients are more prone to secondary bacterial infections, which are strongly linked to the severity of complications of the disease, bacterial coinfections associated with COVID-19 are not widely studied. This work aimed to investigate the prevalence of bacterial coinfections and associated antibiotic resistance profiles among hospitalised COVID-19 patients. Age, gender, weight, bacterial identities, and antibiotic sensitivity profiles were collected retrospectively for 108 patients admitted to the intensive care unit (ICU) and non-ICU ward of a single center in Saudi Arabia. ICU patients (60%) showed a significantly higher percentage of bacterial coinfections in sputum (74%) and blood (38%) samples, compared to non-ICU. Acinetobacter baumannii (56%) and Klebsiella pneumoniae (56%) were the most prevalent bacterial species from ICU patients, presenting with full resistance to all tested antibiotics except colistin. By contrast, samples of non-ICU patients exhibited infections with Escherichia coli (31%) and Pseudomonas aeruginosa (15%) predominantly, with elevated resistance of E. coli to piperacillin/tazobactam and trimethoprim/sulfamethoxazole. This alarming correlation between multi-drug resistant bacterial coinfection and admission to the ICU requires more attention and precaution with prescribed antibiotics to limit the spread of resistant bacteria and improve therapeutic management.
