Cross-partner effects in coalition loyalty programs: the interaction of point redemptions with program sales
Authors: Li Chen , Swaminathan Srinivasan , Kim Junhee 
Published: January 2025

Purpose
Many firms engage customers using coalition loyalty programs. One unique characteristic of these programs is that one partner’s performance can affect the performance of other partners (cross-partner effect). While previous research discusses cross-partner effects from the program sales perspective, the role of point redemptions in cross-partner effects is unknown to marketers. This study aims to investigate this role and discusses its variations among stores of the same chain and those of different chains.

Design/methodology/approach
Using the data of a popular coalition loyalty program, this paper estimates an empirical model that accounts for the dynamics of program sales and point redemptions and the heterogeneity among different partners in the program.

Findings
Cross-partner effects are different between point redemption and program sales. In particular, program sales (point redemptions) in other stores of different chains positively (negatively) affect the focal store’s point redemptions. However, point redemptions in other stores of the same chain as the focal store positively affect the focal store’s program sales.

Research limitations/implications
Coalition loyalty programs are becoming popular around the globe. This research investigates the cross-partner effects of coalition loyalty programs. This is of immense value to practitioners and researchers alike.

Practical implications
This research gives marketing managers insights into the workings of coalition loyalty programs.

Originality/value
This research contributes to loyalty program literature in three ways. First, it complements the literature by investigating the role of point redemption in cross-partner effects. Second, it discusses cross-partner effects in the competing stores from the same chain of the focal store and those from different chains. Third, it explores the dynamic effects of program sales and point redemptions at other stores on program sales at the focal store.

Published: January 2025

PurposeIn this study, the effect of the column’s cross-section shape as a design parameter on resisting blast loads in reinforced concrete (RC) buildings was numerically investigated. To try to give a guideline to the design engineer about the best columns’ cross-section shape when designing an RC building that is more vulnerable to blast loads.Design/methodology/approachThe finite element (FE) analysis was conducted for three RC buildings with different cross-section shapes of columns but with the same area and axial load capacity. The FE analysis was carried out using the Coupled Eulerian-Lagrangian (CEL) in Abaqus/CAE software. The effect of the blast loads resulting from the explosion of 50, 150, and 500 kg TNT bombs with a standoff distance of 3 m on all buildings was investigated.FindingsThe Findings showed that large TNT charges of more than 500 kg with a standoff distance of less than 3 m cause catastrophic damage to RC columns of any cross-section-shaped. Also, RC columns with circular cross-section shapes have the best resistance to blast loads, while RC columns with rectangular sections have the worst resistance.Originality/valueThe CEL technique was used to investigate the effect of columns’ cross-section shape on resisting blast loads on full-scale RC buildings. Also, this research gives a guideline to the design engineer about the best columns’ cross-section shape when designing an RC building that is more vulnerable to blast loads.

PurposeAddressing users’ migration is a prerequisite for the sustainable development of the sharing economy. Ethical concerns that may lead to users’ migration are frequent in sharing economy platforms. Therefore, this study explores whether the long-term governance of sharing economy platforms can effectively mitigate users’ migration caused by ethical concerns.Design/methodology/approachUsing a questionnaire survey of 549 participants, this study investigated the mechanism of users’ migration and governance strategies in the platform ecosystem based on trust theory.FindingsThe results indicate that users’ ethical concerns regarding the platform ecosystem significantly and positively influence their migration. Furthermore, users’ continued trust played a significant mediating role in the relationship between ethical concerns and users’ migration. The results also showed that future orientation and resilience significantly moderated the impact of users’ ethical concerns on their continued trust, thereby weakening this effect.Practical implicationsThe author clarified the relationship between ethical concerns and users’ migration, identified the underlying mechanisms and provided guidance on how to mitigate migration behavior. However, users’ migration is influenced by various factors beyond ethical concerns. In addition to some factors that lead to migration, other factors make users stay on the platform. Future research should integrate multiple factors.Originality/valueThis study reveals the mechanism of action between users’ migration and ethical concerns in the platform ecosystem and sheds light on the output of long-term orientation practices of the platform.

Published: January 2025

PurposeThis study investigates the influence of paradoxical leadership on employee transformative learning in higher education institutions (HEIs). Based on paradox theory, this research examines how a paradoxical mindset mediates this relationship and explores the moderating role of employees’ moral values in developing a paradoxical mindset and fostering transformative learning.Design/methodology/approachThe research adopted a quantitative approach. In three phases, data were collected from 411 randomly selected faculty members of HEIs in Pakistan to assess their perceptions of paradoxical leadership, followers’ paradoxical mindset, moral values and transformative learning outcomes. Structural equation modeling was employed for analysis in AMOS26.FindingsThe findings reveal paradoxical leadership’s positive and significant impact on transformative learning, mediated by developing a paradoxical mindset. Moral values positively moderate the relationship between paradoxical leadership and developing a paradoxical mindset. However, the moderating effect of moral values on the link between a paradoxical mindset and transformative learning was insignificant.Practical implicationsThe study suggests that organizations, particularly HEIs, should cultivate paradoxical leadership to navigate inherent tensions and contradictions, fostering an environment conducive to transformative learning. Developing a paradoxical mindset among employees is crucial for enhancing adaptability and learning, with moral values playing a pivotal role in amplifying the effectiveness of paradoxical leadership.Originality/valueThis study contributes to the literature by providing empirical evidence on the mechanism through which paradoxical leadership influences transformative learning. It extends paradox theory to the context of transformative learning, highlighting the importance of cognitive and ethical dimensions in leadership and learning processes within HEIs.

Published: January 2025

BackgroundA common approach to assessing students' integrated understanding of multiple documents is to analyse their post‐reading written reports. This study investigated to what extent writing self‐efficacy directly and indirectly (via integrative processing) contributed to multiple‐document comprehension as assessed with an integrative writing task.MethodsA sample of Norwegian university students (n = 67) read four documents on a controversial socio‐scientific issue and afterwards wrote reports on the issue without access to the documents. Multiple‐document comprehension was assessed in terms of how well the reports reflected an elaborated and integrated understanding of the four documents' content. A mediation analysis was conducted with students' working memory as a covariate, their confidence in their ability to write a text that integrated content from multiple source documents as a predictor, self‐reports of their integrative processing during reading as a mediator and multiple‐document comprehension as an outcome variable.ResultsThere was an indirect relationship between multiple‐document‐based writing self‐efficacy and multiple‐document comprehension via integrative processing. However, no direct relationship between writing self‐efficacy and multiple‐document comprehension was found. The covariate of working memory uniquely adjusted students' multiple‐document comprehension.ConclusionsIn the context of written assessment of multiple‐document comprehension, multiple‐document‐based writing self‐efficacy and multiple‐document comprehension were indirectly related via integrative processing during reading. The results indicate that not only reading‐related but also writing‐related individual differences may come into play when multiple‐document comprehension is assessed with an integrative writing task.
An Unpublished Inscription From the ʾAwām Sanctuary of ʾAlmaqah: New Evidence for a Royal mqtwy and Sabaean Campaigns in the ‘Land of the Abyssinians’
Authors: Potts Justine 
Published: January 2025

ABSTRACTThis article presents an unpublished Sabaic inscription from the ʾAwām sanctuary of ʾAlmaqah, near Maʾrib. The inscription sheds new light on the mid‐third century ad adventures of a mqtwy (‘officer’) of the Sabaean kings already known from epigraphic evidence: Whbʾwm Yʾḏf. It attests to him waging previously unknown campaigns in ‘the land of the Abyssinians’ (ʾrḍ Ḥbs2t) alongside his own mqtwy, who subsequently dedicated the inscription, with a bronze statue, in thanksgiving to the deity. This is the only military, rather than diplomatic, Sabaean mission abroad to the land (ʾrḍ) of the Abyssinians so far attested. Wider evidence invites us to reconstruct Whbʾwm's extraordinary career and identify an overlooked religious dimension to the mqtwy's function. The inscription shows that divine thanksgiving from mqtwy for monarch took identical form lower down the social hierarchy, adumbrating not only the reciprocity and ritual that underpinned Sabaean elite society, but also the impact of Abyssinian hostilities at a pivotal moment in the twilight of Sabaean history.

Abstract
Parasitoid wasps contribute to biological control services. Parasitoid adults are highly dependent on sugar‐rich resources. Adding flowering plants providing nectar in crop fields promotes parasitoid wasps, but not always pest parasitism because addition of flowering plants may attract parasitoid species that are not directly involved in the control of crop pests.
In a factorial experiment conducted for one year in pesticide‐free orchards, we analysed the effects of three common plant species (Capsella bursa‐pastoris Medik., Veronica persica Poir. and Vicia sativa L.) in association with apple trees on parasitoid wasp recruitment and parasitism of one major apple pest, Dysaphis plantaginea (Passerini). We combined morphological and molecular identifications to characterize the parasitoid communities associated with each plant species.
Parasitoid communities were different between plant species. Plant effects on the abundance of the parasitoid wasps did not depend on the amount of floral resources provided by the tested plants. Over the whole season, the parasitoid wasp species Ephedrus persicae (Froggatt) and Aphidius matricariae (Haliday) involved in D. plantaginea parasitism accounted for 6% of the total parasitoid abundance and were mainly associated with V. persica plots. We observed a higher parasitism rate in apple trees associated with V. persica and a lower number of aphid colonies in apple trees associated with V. sativa.
However, plant treatments had no effect on the abundance of D. plantaginea or on generalist predators and ant occurrences in aphid colonies. As a result, the three plants tested had a limited impact on the rosy apple aphid (RAA) regulation overall.

AbstractIntroductionSouthern Africa has been inhabited by hunter‐gatherers for at least 20,000 years and has received diverse immigration flows in the last 2000 years. The original inhabitants have interacted with the pastoralist migrants from Eastern Africa (∼2000 ybp), followed by the southern Bantu migration arriving some 1000 ybp, and more recently with the European and Asian settlers after the 17th century. Many of the original Khoekhoe and San inhabitants have either become extinct or have disappeared through admixture in South Africa (SA), in a sex‐biased manner involving KhoeSan women.MethodsIn this study, we generated mitochondrial DNA (mtDNA) control region (CR) sequences for 247 South African individuals. The sampling effort was concentrated in regions and populations with historical links to the KhoeSan population groups: admixed (Coloured, Griqua), Nama (Khoekhoe) and Bantu in three provinces. Here we evaluate the composition and extent of connectivity between population groups and regions, and to assess the distribution of haplotypes for the practical application of mtDNA CR data in forensic identifications.ResultsThe analysis of the newly generated sequences revealed 142 distinct haplotypes, of which 122 were unique. Haplogroup L0 was predominant (overall 71.7%). A high‐frequency L0d2a haplotype dominated the pool of the admixed groups with 10%–12.5% incidence overall or per region. Comparative analysis with 545 extant mtDNA CR sequences from South African KhoeSan and admixed descendants revealed extensive population structure and high within‐group haplotype sharing.ConclusionThe observed population and regional variations, combined with the prevalence of high‐frequency haplotypes, align with patterns of matrilocality. These findings highlight the limitations of using mtDNA control region analysis for forensic applications in South Africa.

ABSTRACTPalmoplantar pustular psoriasis (PPPP), or palmoplantar pustulosis (PPP), is a type of psoriasis that affects the skin on the palms and soles. It is characterised by dermatosis and small sterile pustules and is considered a significant burden on patients' quality of life, as there is currently no gold standard treatment or cure. This network meta‐analysis (NMA) compares the efficacy and safety of biologic and non‐biologic medications for PPPP and PPP. Medline, Embase and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched. The efficacy and safety of all medications were assessed through a frequentist NMA using a random‐effects model. Treatments were ranked using the net rank function, yielding P scores. Fourteen RCTs with 1056 participants were included. Guselkumab 100 mg was the most effective for improving PPPGA scores (p = 0.72, RR = 1.31, CI: 0.31–5.57). Guselkumab 100 mg was ranked the highest for achieving PPPASI‐75 (RR = 5.4, CI: 1.26–23.2, p = 0.023). Oral cyclosporine 1 mg/kg/day was ranked the highest for PPPASI‐50 (RR = 2.10, CI: 0.65–6.82). Etretinate 1 mg/kg/day had the highest rate of adverse events (RR = 1.78, CI: 0.92–3.44). Secukinumab 300 mg was associated with the highest rate of serious adverse events (RR = 1.58, CI: 0.21–12.02). Based on the P‐scores from our NMA, guselkumab 100 mg was the most effective for PPPGA improvement, guselkumab 100 mg for PPPASI‐75, oral cyclosporine 1 mg/kg/day for PPPASI‐50, etretinate 1 mg/kg/day had the most adverse events, and secukinumab 300 mg was associated with the highest rate of serious adverse events.Trial RegistrationPROSPERO registration number: CRD42023460842

ABSTRACTProblemAlthough it is still uncertain whether Severe Acute Respiratory Coronavirus (SARS‐CoV‐2) placental infection and vertical transmission occur, inflammation during early pregnancy can have devastating consequences for gestation itself and the growing fetus. If and how SARS‐CoV‐2‐specific immune cells negatively affect placenta functionality is still unknown.Method of studyWe stimulated peripheral blood mononuclear cells (PBMCs) from women of reproductive age with SARS‐CoV‐2 peptides and cocultured them with trophoblast spheroids (HTR‐8/SVneo and JEG‐3) to dissect if SARS‐CoV‐2‐activated immune cells can interfere with trophoblast functionality. The activation and cytokine profile of the PBMCs were determined using multicolor flow cytometry. The functionality of trophoblast spheroids was assessed using microscopy, enzyme‐linked immunosorbent assay (ELISA), and RT‐qPCR.ResultsSARS‐CoV‐2 S and M peptides significantly activated PBMCs (monocytes, NK cells, and T cells with memory subsets) and induced the upregulation of proinflammatory cytokines, such as IFNγ. The activated PBMCs did not impact the viability, growth rate, and invasion capabilities of trophoblast spheroids. Furthermore, the hormonal production of hCG by JEG‐3 spheroids was not compromised upon coculture with the activated PBMCs. mRNA transcript levels of genes involved in trophoblast spheroid functional pathways were also not dysregulated after coculture.ConclusionsTogether, the findings of our in vitro coculture model, although not fully representative of in vivo conditions, strongly support the claim that the interaction of SARS‐CoV‐2‐activated peripheral blood immune cells with trophoblast cells at the fetal–maternal interface does not negatively affect trophoblast functionality. This goes in hand with the recommendation of vaccinating pregnant women in their first trimester.

AbstractBackgroundTo investigate the incidence, demographic characteristics, etiologies, surgical interventions, hospital stays, and neurologic outcomes associated with watersport‐related traumatic spinal cord injuries (TSCI) in New Zealand.MethodsRetrospective study collected data from New Zealand's two spinal rehabilitation units, the Auckland Spinal Rehabilitation Unit (ASRU) and the Burwood Spinal Unit (BSU). It included adults aged over 16 years, between January 2007 and December 2021 with new TSCI secondary to traumatic watersport activities. Variables assessed include type of water‐related activity, length of hospital stay, surgical intervention and neurologic outcomes, categorized by the American Spinal Injury Association (ASIA) impairment scale.ResultsData from 80 patients were analysed. The mean annual incidence of water‐related TSCI was 1.141 per 1,000,000 per year, predominantly affecting males (68 males vs. 12 females) with a mean age of 31.1 years. Maori had the highest incidence rate (2.02 per 1,000,000). Diving was the leading cause of TSCI (57 cases), particularly from pool and wharf accidents. Most injuries occurred between December and March. Surgical intervention was performed in 89% of cases. The average hospital stay was 93.65 days, with the cervical region being the most commonly affected (85.1%).ConclusionsWatersport‐related TSCI in New Zealand predominantly affects the young, Maori and males, with cervical spine injuries, particularly from diving accidents being most common. Seasonal trends suggest a need for targeted prevention during warmer months. These findings provide insights for public health initiatives, clinical management and the development of prevention strategies.
