Shopper Search in Response to Conditional Promotions: A Function of Basket Sizes and Incentive Types
Authors: Kulkarni Atul A. , Yuan Hong 
Published: February 2025

ABSTRACTConditional promotions are designed to entice consumers to increase their basket sizes to meet a preset promotional threshold. In this research, we examine consumers' basket sizes, promotional thresholds, incentive framing and seemingly irrelevant cues in shopping environment as the factors that may jointly influence the effectiveness of a conditional promotion in inducing shoppers to increase their basket sizes. Our findings from five studies demonstrate that (i) the difference between basket sizes and promotional thresholds or seemingly irrelevant cues in shopping environment may induce an experience of psychological distance, (ii) the experience of psychological distance may interact with incentive framing to influence consumers' search likelihood in response to a conditional promotion such that psychological proximity (remoteness) leads to higher search likelihood in response to negatively (positively) framed incentives. We found that this effect is consistent across studies with different values of basket sizes and promotional thresholds and across behavioral and self‐reported measures representing search likelihood.

Authors: Kirane Mokhtar , Aounallah Radhouane , Jlali Lotfi 
Published: February 2025

ABSTRACTThis paper shows that long‐term stability and blowing‐up solutions for a nonlinear wave equation with a nonlocal damping of Choi and MacCamy type and a nonlocal dispersion can occur. The method of proof of general decay relies on a suitable Lyapunov functional. The method of proof of blow up in finite time of some solutions relies on the concavity method.
Exact Controllability for the Quasilinear Perturbations of the Kawahara Equation
Authors: Jin Yanpeng , Fu Ying , Wu Xiaoping 
Published: February 2025

ABSTRACTThis paper is devoted to studying the exact controllability for the Kawahara equation under the influence of quasilinear perturbations for sufficiently small data on the circle with localized control, the nonlinearities containing up to five space derivatives and having a Hamiltonian structure at the space derivatives of the highest order. Firstly, we conjugate the associated linearized operator to a time‐dependent variable coefficient operator up to a bounded remainder. The major difficulties come from five space derivatives and the coupling of the coefficient of the highest order term with the coefficients of other terms. The strategy adopted is to look for appropriate transformations, which are reversible and satisfy the sharp bounds for the reducibility. Then, from the observability and controllability of the corresponding linear control problem, the existence of the right inverse for the linearized operator is verified. Finally, the application of the Nash–Moser–Hörmander theorem implies the exact controllability for the Kawahara equation with the quasilinear perturbations.

ABSTRACTIntroductionEarly diagnosis of rheumatoid arthritis (RA) is crucial to prevent joint damage and improve treatment outcomes. RA cases that are not polyarticular at onset, and/or are not beginning in the hand joints may face diagnostic delays, because of more convincing alternate diagnoses. This study examines the prevalence of onset pattern and location and its impact on diagnostic timing and disease progression in RA.MethodsThis prospective cross‐sectional study was conducted at Sandeman Provincial Hospital Quetta, Pakistan (January–December 2022). Adults aged 17 years & above with RA meeting ACR criteria 2010 were included using a consecutive sampling technique. The associations were measured by Chi‐squared and Cramer's V test. Bivariate and multinominal Regression models were used to analyse the duration and pattern of disease, delay in diagnosis and location of onset.ResultsTwelve hundred RA patients (966, 82.8% female) with a median age of 42 (IQR: 33–55), and a median disease duration of 5 years (IQR: 2–8), both positively skewed, were included in the study. At‐least 408 (34%) patients had non‐polyarticular onset at initial presentation, and around 458 (38%) patients had the onset on illness not beginning in the small joints of hands. Non‐hand onset was significantly associated with age of onset, being 2.5 times higher in juvenile onset than in adult onset (OR = 2.515, p = 0.035). A diagnostic delay of 17.8 ± 27.9 months was found in the cohort, correlating significantly with total duration of disease (p < 0.01), pattern of disease (polyarticular vs. non polyarticular, p < 0.050) and with female gender (p = 0.014) but not with area of onset.ConclusionsRA onset outside the hands with non‐polyarticular patterns accounts for nearly one‐third of cases, emphasising the need for a more easily accessible rheumatology care to reduce delays and mitigate prolonged disease impact.
When Grand Societal Challenges Stimulate the Creation of Public Value: A Study of Nurses in a Non‐Western Public Healthcare Sector
Authors: Mousa Mohamed , Althalathini Doaa , Puhakka Vesa 
Published: February 2025

ABSTRACTThis study aims to explore the extent to which grand societal challenges motivate street‐level bureaucrats to actively create public value and why. The empirical sample comprises semi‐structured interviews with 36 nurses working in four public hospitals in Egypt. Thematic analysis was subsequently applied to the transcripts from the semi‐structured interviews to highlight the main themes linked to this topic. The findings show that the respondents (nurses in this case) have accepted the idea of creating public value through working extra unpaid hours, engaging actively in night shifts, and treating incoming refugees. This is a result of the following three categories of motives: Humanitarian (religious considerations, appreciation and praise from refugees, desire to emigrate), Job‐related (greater sense of discretionary power, implementing the orientation or directions of the hospital administration, exploiting recent developments in medical instruments) and Patriotic motives (understanding that refugees are a source of foreign currency, creating a culturally diverse climate which Egypt lacks, ensuring partnership between hospitals and the private sector). This study contributes to emerging literature on grand societal challenges and the creation of public value by street‐level bureaucrats on which empirical studies are rare, particularly in the context of developing nations.

ABSTRACTA better understanding of positron emission tomography (PET) response in nodular lymphocyte‐predominant Hodgkin lymphoma (nLPHL) is critical for incorporating PET into prospective trials. PET scans from Children's Oncology Group study AHOD03P1 for patients less than 22 years with low‐risk nLPHL, treated with three cycles of doxorubicin, vincristine, prednisone, and cyclophosphamide chemotherapy, were retrospectively reviewed and assigned Deauville 5‐point scale (5PS) scores. Five‐year post‐PET event‐free survival was 90.1% (80% CI: 85.2%–93.4%) for PET‐negative (5PS 1–3) and 66.7% (80% CI: 36.4%–85.0%) for PET‐positive (5PS 4–5) patients. PET response after three cycles of low‐dose chemotherapy is predictive of relapse risk for low‐risk nLPHL.
Optimization of EMI shielding performance of MXene‐epoxy nanocomposite coatings: MXene Loading and thickness study
Authors: Roohani Yasamin , Yahyaei Hossein 
Published: February 2025

AbstractThe burgeoning prevalence of electronic devices necessitates effective control of electromagnetic interference (EMI) to prevent device malfunctions and safeguard environmental and human health. MXene, with its unique combination of high electrical conductivity and large surface area, emerges as a promising candidate for EMI shielding applications. This study investigates the influence of MXene nanoparticle concentration and coating thickness on the EMI shielding effectiveness (EMI SE) of epoxy‐MXene nanocomposite coatings. Ti3C2 MXene was synthesized and incorporated into epoxy matrices at varying loadings (3–30 wt.%) to fabricate coatings with thicknesses of 100 μm and 1 mm. Results demonstrate a significant enhancement in EMI SE, ranging from 5 to 39 dB in the X‐band (7.5–13 GHz), with increasing MXene content. Moreover, the mechanical properties of the epoxy matrix were observed to improve with the addition of MXene, particularly at higher concentrations. Notably, while low MXene loadings initially resulted in a slight reduction in Young's modulus, subsequent increases in MXene content led to substantial enhancements in both modulus and strength. Dynamic mechanical analysis revealed a trend towards increased elastic behavior and reduced energy dissipation with higher MXene content. This study highlights the potential of MXene‐based epoxy composites as high‐performance EMI shielding materials with tailored mechanical properties.Highlights

Reinforcement of jute fiber and aluminum trihydrate in a novel biopolymer synthesized through citric acid and glycerol (polyglycerol citrate)
Authors: Malik Rizwan Ahmed 
Published: February 2025

AbstractA novel thermoset biopolymer was developed from citric acid and glycerol (referred to as Polyglycerol citrate (PGC)) through polycondensation. PGC is a completely biodegradable and water‐soluble polymer, but it has poor thermal stability, fire retardant and mechanical properties. To enhance the usability of this material in food packaging, insulations, and other domestic products, its strength was enhanced by reinforcement through jute fiber (JF) which is also biodegradable and environmentally friendly. The thermal stability and fire‐retardant properties of the jute/PGC composite were improved by incorporating aluminum trihydride (ATH) particles in it. The concentration of ATH was varied between 0% and 12% to evaluate the optimum composition for improved thermal, mechanical and flammability properties. The strength and modulus of the material were evaluated using a tensile test while the fire retardant and thermal properties were determined using burning tests, cone calorimetry and thermogravimetric analysis. The surface morphology was studied through a scanning electron microscope. The maximum tensile strength was obtained by incorporating 9% ATH in the jute/PGC composite, which is 236% higher than the strength of neat PGC resin. Similarly, the heat release rate of jute/PGC composite was reduced by 17% with the incorporation of ATH particles. Also, the burning rate of jute/PGC was reduced by 72%. Thermal stability was also observed to improve. Possible chemical interaction between the constituents of the composite was confirmed through Fourier transform infrared spectroscopy (FTIR). The biodegradation of the composite specimens was validated through a soil burial test.Highlights

Published: February 2025

AbstractThis study investigated the possibility of integrating natural rubber (NR) with various forms of cellulose (Cell) to develop new composites that enhance physical properties. For the first time, the innovative composites were fabricated from blending the modified deproteinized natural rubber (DPNR) by a graft copolymerization process using styrene as the continuous phase and cellulose as the reinforcing phase. Cellulose interacts with rubber segments, leading to improvements in heat resistance and tensile strength in comparison with NR. Herein, microcrystalline cellulose (MCC) and cellulose nanofiber (CNF) are the two cellulose forms utilized. The particle size and the amount of the cellulose have an impact on the thermomechanical properties of the composites. Both MCC/DPNR‐g‐PS 1% and CNF/DPNR‐g‐PS 1% demonstrated an improvement in mechanical properties over conventional DPNR and DPNR‐g‐PS. Notably, tensile strength increased threefold for MCC/DPNR‐g‐PS 1% (6.52 ± 0.31 MPa) and fivefold for CNF/DPNR‐g‐PS 1% (11.97 ± 0.34 MPa) compared to DPNR (2.09 ± 0.12 MPa). Furthermore, the glass transition temperature increased by 1.31°C for MCC/DPNR‐g‐PS 1% and by 1.34°C for CNF/DPNR‐g‐PS 1% compared to DPNR, indicating improved thermal stability. The decomposition temperature also increased for both composites. These findings showed that the novel structural formation of Cell/DPNR‐g‐PS composites offers promising alternatives to conventional vulcanized NR reinforced with sulfur, carbon black, or silica. The improved thermomechanical properties of these composite materials make them potential candidates for various applications.Highlights

V‐shaped truss‐like cores for improving mechanical properties of woven lattice sandwich composites
Authors: Wang Ben , Yan Qu , Fan Hualin 
Published: February 2025

AbstractWoven lattice sandwich composites with 1‐shaped truss‐like cores have the disadvantage of weak core shear performance. In this paper, double‐layered woven lattice sandwich (DWLS) composite panels with V‐shaped truss‐like cores were designed and manufactured to solve the weak core shear performance of 1‐shaped truss‐like cores. Flatwise compressive and three‐point bending experiments were performed on these DWLS panels. Results indicate that V‐shaped truss‐like cores improve the flatwise compressive strength and stiffness, and the core shear stiffness and strength of panels compared to 1‐shaped truss‐like cores. The V‐shaped core piles fracture at the end, while the 1‐shaped core piles fracture at the middle. The improved core shear stiffness makes the V‐shaped panel exhibit more excellent mechanical performance. In three‐point bending experiments, the obvious inflection feature and its induced large deformation appear in the supported end but are suppressed as the span increases. The theoretical approach was used to calculate core shear stiffness, and the analytical results are in good agreement with the experimental patterns.Highlights

Published: February 2025

ABSTRACTObjectiveTo investigate the current genetic counseling practices involving a cfDNA result indicating mosaic monosomy X of likely maternal origin, and to better understand the perspectives of patients who have received this result.MethodA total of 60 prenatal genetic counselors completed surveys about their experiences with this result, cfDNA consenting practices, and management practices. In addition, qualitative interviews were conducted with 5 patients to gain insight into their experiences with result disclosure and follow‐up care.Results95% of genetic counselors reported feeling prepared to counsel on these results. However, responses to current practices varied. Of the genetic counselors surveyed, 62% state that their approach to management does not differ if the patient is symptomatic. Responses indicated 95% of genetic counselors ordered a karyotype for maternal diagnostic testing, and 30% ordered a chromosomal microarray. Interviews of patients found that 100% were not aware of the possibility of receiving an incidental finding from cfDNA. Patients reported feeling surprised, confused, and worried when they received their results.ConclusionThe majority of genetic counselors report feeling confident in counseling these results, but their current practices vary. Patients who receive these results are found to have a difficult time adapting due to feeling surprised and confused. Based on these findings, we believe professional practice guidelines are needed to establish clear management recommendations, which in turn would hopefully decrease patient and provider stress.

Published: February 2025

AbstractAmong commercial polymer materials, polypropylene (PP) is the most preferred in the world. Low‐density materials such as polymers and polymer composites are increasingly used to produce lighter structures. In the automotive industry, these parts are used for painting. Due to the non‐polar surface chemistry of PP, PP surfaces have low surface energy, which causes weak bonds in coating, painting, and bonding processes. Therefore, various physical and chemical processes are used to increase the surface energy of PP first, and then the surface is prepared with a primer before painting. However, the primer material and surface treatments used have disadvantages such as extra cost, being harmful to the environment, and the use of fossil fuels. Atmospheric pressure plasma (APP) surface treatment has recently become an alternative to traditional methods. In this study, the chemical and physical changes caused by APP surface treatment on PP surfaces were examined, the effects of process parameters were investigated, and the paintability of surfaces with and without primer was investigated.Highlights
Primerless painting feasibility per standards is under investigation.
Eco‐friendly alternatives to traditional pre‐paint treatments are under study.
Polypropylene surface properties' effects on painting are under study.
Optimal atmospheric pressure plasma parameters for painting are determined.

AbstractThis study investigates the effect of incorporating recycled polymethyl methacrylate (r‐PMMA) into polylactic acid (PLA) and further modifications with a bio‐based compatibilizer (epoxidized soybean oil [ESO]). Various PLA:r‐PMMA ratios were evaluated, with and without ESO. Blending r‐PMMA into PLA significantly influenced mechanical properties. The 10PLA90r‐PMMA blend showed enhanced elongation at break (6.10%) and tensile toughness (1686 kJ/m3) compared to pure PLA (3.34% and 737 kJ/m3, respectively), addressing PLA's inherent brittleness. The 30PLA70r‐PMMA composition exhibited a tensile strength (TS) of 51.44 MPa and significant tensile toughness (1237 kJ/m3). Thermal analysis revealed an increase in the glass transition temperature (Tg) with higher r‐PMMA content, reaching 124°C for 100r‐PMMA, and a decrease in crystallinity percentage from 68.17% (pure PLA) to 30.43% (50PLA50r‐PMMA). Incorporating ESO into a 50 PLA50r‐PMMA blend modified its properties. Adding 3 parts per hundred resins (phr) ESO improved elongation at break (5.68%) and tensile toughness (1302 kJ/m3) while reducing TS (35.03 MPa). At 6 phr ESO, flexibility was maximized with an elongation of 6.37%, but TS decreased to 26.89 MPa. These findings highlight the synergy between r‐PMMA and ESO in enhancing PLA's performance for sustainable applications and balancing mechanical and thermal properties while addressing environmental challenges.Highlights

ABSTRACTObjectivesFear of cancer recurrence (FCR) is a prevalent unmet need for people affected by cancer, in the context of limited healthcare resources. Stratified‐care models have potential to meet this need, while reducing resource demands. This study aimed to evaluate the feasibility and acceptability of screening procedures and interventions within the Fear‐Less stratified‐care model among those impacted by early‐stage cancer.MethodsPeople affected by breast, head and neck, or gynaecological cancer, who had completed curative treatment, were screened for FCR. Individuals experiencing moderate FCR (scored 13–21 on the Fear of Cancer Recurrence Inventory‐Short Form; FCRI‐SF) were offered a purpose‐developed clinician‐guided self‐management intervention, while those experiencing severe FCR (FCRI‐SF score ≥ 22) were offered individual therapy (ConquerFear). Re‐screening and evaluation measures were completed post‐intervention.ResultsSeventy‐six (70%) of 109 eligible people completed screening, with 53/76 participating in the Fear‐Less model evaluation. Thirty‐nine of 53 participants reported FCR and were referred to an intervention; 30/39 (77%) accepted the referral. Fifteen (83%) of 18 participants completing the self‐management intervention reported reading ≥ 75% of the resource at 5 weeks, with 10/18 (56%) reporting clinically meaningful (≥ 10%) reductions on the FCRI‐SF post‐intervention. Qualitative feedback indicated screening and the stratified‐care received were acceptable.ConclusionsScreening procedures and interventions forming the Fear‐Less model appear feasible and acceptable for identifying and treating FCR among people affected by early‐stage cancer. Although further research is required to evaluate its efficacy, this model has the potential to meet a major unmet need, where psychosocial services are limited amid increased demand.Trial RegistrationThis study was retrospectively registered on the Australian New Zealand Clinical Trials Registry (ACTRN12622000818730) on 10/6/2022.
