Published: July 2023

AbstractAtmospheric aerosol deposition into the low latitude oligotrophic ocean is an important source of new nutrients for primary production. However, the resultant phytoplankton responses to aerosol deposition events, both in magnitude and changes in community composition, are poorly constrained. Here, we investigated this with 19 d of field and satellite observations for a site in the subtropical North Atlantic. During the observation period, surface dissolved aluminum concentrations alongside satellite‐derived aerosol and precipitation data demonstrated the occurrence of both a dry deposition event associated with a dust storm and a wet deposition event associated with strong rainfall. The dry deposition event did not lead to any observable phytoplankton response, whereas the wet deposition event led to an approximate doubling of chlorophyll a, with Prochlorococcus becoming more dominant at the expense of Synechococcus. Bioassay experiments showed that phytoplankton were nitrogen limited, suggesting that the wet deposition event likely provided substantial aerosol‐derived nitrogen, thereby alleviating the prevalent nutrient limitation and leading to the rapid observed phytoplankton response. These findings highlight the important role of wet deposition in driving rapid responses in both ocean productivity and phytoplankton community composition.
MY LAST VISIT WITH FRANCES HESSELBEIN
Authors: Goldsmith Marshall 
Published: July 2023

AbstractThe author, a pioneer in the field of business education and leadership coaching, was one of the closest confidantes and colleagues of Frances Hesselbein. He recounts details of their relationship, including how Frances introduced him to Peter Drucker in 1981, when Frances was CEO of the Girl Scouts of the USA, and Drucker was consulting for the organization on a pro bono basis. He also recounts deathbed visits with both Drucker, in 2005, and Frances, in 2022. “My last visit with Frances,” he writes, “illustrated to me why she was such a great human being. Her entire life was based in service to others; she devoted herself to being a professional. She never complained. She never whined, and it was always about us and not about her.”
FRANCES HESSELBEIN: METICULOUS PREPARATION FOR A PUBLIC ROLE
Authors: Helgesen Sally 
Published: July 2023

AbstractThe author, who has been cited in Forbes as the world’s premier expert on women’s leadership, writes about her longstanding friendship and history with Frances Hesselbein, beginning in 1989, toward the end of Frances’ 13 years as CEO of the Girl Scouts of the USA. “She had upended the hierarchy that the Girl Scouts had adopted from the military upon its founding,” the author writes, “putting herself in the center rather than at the top, and drawing concentric circles around an inner core.” Nearly 30 years later, the author interviewed her for a profile in Strategy + Business magazine, in which Frances noted: “When you’re a leader, people watch your every move and listen to every word you say. They can over‐interpret because they feel dependent upon your opinion. So you need to honor that, and weigh your words.”

AbstractBackgroundAlpha‐synuclein (SNCA) copy number variations (CNV) have been certified as a causative mutation in patients with familial and sporadic Parkinson's disease (PD).CaseWe report three SNCA duplication cases diagnosed as PD. Through whole‐exome sequencing, we identified a de novo 4.56 Mb repeated region in one patient and a 2.50 Mb repeated region in familial PD with two patients.Literature reviewIn review of previous cases, we suggest that aggressive behavior is more remarkable in CNV4 patients. Meanwhile, frequency of cognition decline and dementia were slightly increased in CNV4 patients. We also illustrate a younger onset age in offspring than parent in familial SNCA multiplication PD cases. No difference was observed in disease duration between parent and offspring generation.ConclusionsOur findings demonstrated the clinical and genetic characteristics in PD with SNCA multiplication and provided strong evidence for genetic anticipation. These results may be instructive for future disease diagnosis and genetic counseling.
Mobile parcel lockers with individual customer service

Published: July 2023

AbstractThe ongoing growth of e‐commerce deliveries has led to a significant increase in last‐mile delivery volumes. New technologies are being investigated to provide these deliveries efficiently and in a customer‐friendly manner. A common practice is to use fixed parcel lockers (FPLs) to make deliveries independent from the presence of the customer as is the case in attended home deliveries (AHDs). FPLs are usually installed at key locations in cities, and customers can collect their package at any time once it has been delivered to this particular location. Mobile parcel lockers (MPLs) represent a new idea: they can be parked for temporary collection of items at different locations, keeping the pickup distance to the customer short and avoiding high infrastructure costs. However, customers need to collect their parcels within a restricted time window. This service is supposed to become especially efficient through autonomously operating vehicles that can move MPLs at low costs. In this article, we introduce the heterogeneous locker location problem to study the effects of fleets combining two of the services—FPLs, MPLs, AHDs—within one framework. In our comparison, we consider that customers may have different expectations regarding their maximum pickup distance as well as their temporal flexibility in accepting deliveries. A fixed fleet is applied to maximize the number of customers served, respecting individual customer preferences in terms of pickup distances and time windows. We evaluate the different delivery services regarding managerial insights on service quality and efficiency. In the experiments, we analyze the impact of structural demand differences and different fleet sizes, as well as the operational fleet utilization and the individual customer experience. Results show the potential to increase the number of customers served by about 14%–19% through the use of MPLs while considering individual customer preferences.

Published: July 2023

AbstractAims(1) To review and synthesize research on the contributions of nurses to rehabilitation in inpatient geriatric rehabilitation units (GRUs), and (2) to compare these reported contributions to the domains of international rehabilitation nursing competency models. The roles and contributions of nurses (e.g. Registered Practical Nurses, Registered Nurses and Licensed Practical Nurses) in GRUs are non‐specific, undervalued, undocumented and unrecognized as part of the formal Canadian rehabilitation process.DesignArksey and O'Malley's methodological framework for scoping reviews and the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses Extension for Scoping Reviews guidelines were used.MethodsSix databases were searched for relevant literature: MEDLINE, PsychINFO, CINAHL, EMBASE, SCOPUS and Nursing and Allied Health. English articles were included if they examined nursing roles or contributions to inpatient geriatric rehabilitation. Integrated synthesis was used to combine the qualitative and quantitative data, and thematic analysis was used for coding. Three sets of international competency models were amalgamated to explore how different nurse roles in geriatric rehabilitation were portrayed in the included literature.ResultsEight studies published between 1991 and 2020 were included in the review. Five main geriatric rehabilitation nursing roles were generated from synthesis of the domains of international rehabilitation nursing competency models: conserver, supporter, interpreter, coach and advocate.ConclusionsNurses working in inpatient geriatric rehabilitation are recognized more for their role in conserving the body than their roles in supporting, interpreting, coaching and advocacy. Interprofessional team members appear to be less sure of the nurses' role in the rehabilitation unit. Nurses themselves do not acknowledge the unique rehabilitation aspects of care for older adults. Enhancing formal education, or adding continuing education courses, to facilitate role clarity for nurses in geriatric rehabilitation could improve nurses' and interprofessional healthcare team members' understandings of the possible contributions of nurses working in rehabilitation settings.

AbstractAimTo assess the social cognitive elements of the stigma of mental illness (knowledge, attitudes and behaviours) among healthcare professionals (HCPs) in Jordan.DesignA cross‐sectional descriptive design.MethodsA total of 206 HCPs were conveniently recruited from general hospitals in Jordan. The mental attitude, knowledge and intended behaviours scales were used to measure stigma elements.ResultsParticipants reported a moderate level of knowledge, a moderate negative attitude and a moderate or not greater interest to deal with people with mental health illnesses. The bivariate correlation revealed a negative significant correlation between HCPs' knowledge and attitude, indicating that HCPs with more knowledge significantly have more positive attitude (lower average score) towards those suffering from the illness. A more significant correlation was found between HCPs' knowledge and behaviour. The HCPs who had more knowledge were holding more interest and willingness towards dealing with persons with mental illness.Patient or Public ContributionNegative attitudes among HCPs demand awareness programmes pertaining to the stigma of mental illness to afford higher standards of practice for patients with mental problems.

AbstractSpray up is a method intensively applied for short fiber reinforced plastic (FRP) products manufacturing. The current study investigated the application of spray up for impregnation and manufacturing of long fiber FRP products, which can bring major advantages of minimized impregnation time and fewer product defects. Computational fluid dynamics (CFD) modeling was applied to investigate the spray and deposition characteristics of the viscous general‐purpose unsaturated polyester resin on a glass fiber preform. Validation of CFD results was done using phase Doppler anemometer and camera imaging techniques, and errors were calculated. Droplet velocity distributions 30 cm from the nozzle tip showed an average absolute percentage error of 4.3% and root mean square error value of 0.68 m/s, which are minimal. CFD and experimental values of sprayed resin area coverage (main area) after 4 s of spray were 17 and 16.3 cm in diameter, respectively; this is a relatively small error. Resin pool thickness on the target surface was variable, values predicted numerically. Non‐uniformity of pool thickness can be compensated by using appropriate compaction mechanisms. It is also possible to impregnate large size and complex shape products using multiple nozzles of proper arrangement.

AbstractWith the rapid evolution of integrated circuits and electronic devices, considerable research efforts are dedicated to thermally conductive but electrically insulative composites that may successfully allay “hot spot” concerns during device operation. In this study, a green, cheaply and effective method was proposed to improve thermal conductivity coefficient (λ) of boron nitride/epoxy composites by modifying boron nitride sheet (BN) surface with TACu nanoparticles that synthesized from tannic acid (TA) and copper sulphate. As a result, the TACu nanoparticles and BN work in concert to improve the thermal conductivity of the BN/epoxy composite. The ideal thermal conductivity coefficient, 1.61 W/mK, was present when the mass fraction of the created filler, BN@TACu, is 30 wt%. This value is 7.3 times higher than that of pure epoxy resin (0.22 W/mK) and significantly higher than the reported BN/epoxy composites containing 30 wt% fillers. Moreover, the interface compatibility between BN and epoxy resin is also significantly improved by the TACu nanoparticles on BN surfaces, giving the composites improved thermal and mechanical characteristics. This technology for BN surface modification has a lot of practical potential in the present electronic sector since it is relatively straightforward and easy to scale up.

Published: July 2023

AbstractEthylene vinyl acetate copolymer (EVA) was modified by expandable graphite (EG) and polyphosphoric acid (PPA) in melt state and the obtained EVA/EG/PPA composite was studied regarding its fire behavior, thermal endurance, water resistivity, processability, and mechanical property. The outcomes evince that the combination of EG and PPA in proper mass ratio can improve fire retardancy, thermal stability, processability, and reduce smoke and toxic gas releases of EVA upon combustion significantly. The EG/PPA combination exhibits very high flame retardant efficiency to EVA in that only 10 wt% loading is enough to make EVA obtain V‐0 rating in UL‐94 test. Moreover, the flame‐retarded EVA/EG/PPA composite displays excellent water resistance and acceptable mechanical property. The EVA/EG/PPA (90/7.5/2.5) composite can produce coherent intumescent char on composite surface, which has good heat endurance and hinders heat transmission from fire to interior of composite. The flame retardation occurs in condensed phase and the intumescent char plays a pivotal role. The presence of PPA endows EVA composite with good melt flowability, which has presented a striking contrast to other flame retardants.Highlights
The combination of EG and PPA has very high flame retardant efficiency to EVA.
The EVA/EG/PPA composite has better fire safety and processability than EVA.
The EVA/EG/PPA composite still maintains acceptable mechanical property.
The expanded char from EVA/EG/PPA composite hinders heat transfer effectively.

Published: July 2023

AbstractInjection molding is a widely used method for production of plastic components, offering both simplicity and high strength. In this study, secondary injection molding was utilized to weld polyamide 6 (PA6). The welded samples were evaluated for the welding strength via a shear tensile test. Three process parameters of mold temperature, injection temperature, and injection speed were varied to determine the optimal conditions for welding. A polarizing microscope analysis of the welding interface revealed formation of a shish kebab layer (SKL) structure, which significantly contributed to the welding strength. A differential scanning calorimetry analysis of the welded samples showed that changes in the crystallinity at the interface were closely related to the welding strength under different injection molding conditions. To analyze the crystal phase of the interface after welding, we propose the use of Fourier‐transform infrared spectroscopy area scanning to obtain the relationship between the phase transformation and welding strength. Additionally, microhardness testing is proposed as a means of evaluation of the welding effect. Overall, this study highlights the importance of optimization of process parameters in secondary injection molding to achieve strong welds in PA6, where the SKL structure and crystallinity changes at the interface have crucial roles.Highlights
The high welding shear strength reaches 80% of the base material.
The interfacial crystalline structure has a significant impact on the strength.
The crystalline changes were analyzed using FTIR region scanning.
The relationship between microhardness and welding strength was obtained.
The wide‐ranging conditions have reference value for industrial production.
Role‐overload and self‐esteem affecting teachers career satisfaction: Serial mediation through work engagement and job satisfaction

Published: July 2023

AbstractThis study examines the effects of role‐overload (RO) and self‐esteem (SE) on career satisfaction (CS) through work engagement (WE) and job satisfaction (JS). It follows the social cognitive career theory (SCCT) and job demands‐resources (JD‐R) model. A quantitative survey was conducted on Indian school teachers (n = 630). A serial mediation model was developed to examine the proposed relationship. Hypotheses were tested by SEM and bootstrapping to verify the direct/indirect effects. The results reveal that SE, directly and indirectly, influence CS. The serial mediation was found between RO on CS through SE, WE, and JS. WE and JS also serially mediated between SE and CS. However, RO does not affect CS directly but through serial mediation. Study proposes a structural model with organizational and individual factors influencing CS. Unlike previous researchers, this study combines personal resources and organizational demands predicting CS. The study helps to understand the connecting link between SCCT and JD‐R theory. Organizations can make use of this model for developing CS by managing RO through interventions.
Don't go it alone: Locating the sexual health curricula available to families of students with intellectual disability

Published: July 2023

AbstractStudents with intellectual disabilities (ID) have reduced access to sexuality education at school, tasking families with filling the gap. This limited access contributes to persistent health inequities, psychosocial risk, and reduced self‐determination for individuals with ID. To understand the resources that families may encounter when filling this service gap, a naturalistic scoping review and content analysis of ID‐specific sexual health curricula (SHC) was conducted. This analysis found a limited number of SHC available to family members who may seek them out online, and even fewer SHC designed for the specific needs of family‐led delivery. While curricula identified in this study generally include the minimum recommended content areas for comprehensive sexuality education, they less frequently provide actionable guidelines for caregivers tasked with adapting teaching practices and outcomes assessment to the diverse profiles of students with ID. By understanding the SHC available to families of students with ID, school psychologists can improve their partnerships with families, disseminate needed resources, implement collaborative intervention practices, and advocate for inclusive sexuality education practices.
Osteogenic activity of bone: Novel approach of polyvinylidene fluoride films, marrow blood supply, and ultrasound stimulation
Authors: Zuchuat Jésica , Halter Christian , Zalazar Martín 
Published: July 2023

AbstractElectric fields used in bone stimulation are based on the application of direct current, but some drawbacks exist, such as the need for an external power source. Piezoelectric poly(vinylidene fluoride) (PVDF) has attracted interest for biomedical applications due to its flexibility, low toxicity, and the piezoelectric response to mechanical stimuli. This study aimed to investigate the effects of PVDF films on bone regeneration in rabbit tibias to assess the potential improvement in osteogenesis. An initial exploratory experiment was performed to determine optimal parameters for regulating the marrow blood supply. The second experiment focused on examining the effects of ultrasound stimulation on the implant's osteogenic capacity. The results showed that PVDF films have a notable impact on the extraskeletal bone formation and bone density in a secluded microenvironment with and without microperforations. At 60 days after surgery, tibias with marrow blood supply reached higher bone volumes and density and they were consistent with the cellular activity. Our results suggest that piezoelectric PVDF films have osteogenic characteristics and can be used to enhance new bone formation in a secluded space, thus reinforcing their biocompatibility nature. Additional studies are required to analyze the benefits of ultrasound stimulation.

AbstractIn recent decades, flexible and wearable strain sensor has shown promising application prospects in human motion detection, medical rehabilitation, human‐computer interface, etc. Conductive polymer composites (CPCs) composed of conductive fillers and elastic polymers demonstrate the merits of excellent flexibility, high stretchability, and good tensile recovery. They are usually used as flexible strain sensors with large working range and high sensitivity. This review introduces in detail the preparation, morphologies and strain sensing performance of different CPC sensors including one‐dimensional fibers, two‐dimensional films, three‐dimensional foams and hydrogels. CPCs with different structures show their unique advantages in reducing the percolation threshold and/or improving the sensing performance. The multi‐functionalities of CPC strain sensors with extended applications are also reviewed. Finally, we summarize the current challenges and outlook the future development of the CPC strain sensors.
