Authors: Kimura Takuma , Shinmura Ken 
Published: July 2023

AimGeriatricians and primary care physicians in Japan are expected to provide care to older patients with multimorbidity.MethodsA questionnaire survey was carried out to understand the current approaches to older patients with multimorbidity. A total of 3300 participants, including 1650 geriatric specialists (G) and 1650 primary care specialists (PC) were enrolled. A 4‐point Likert scale was used to score the following items: diseases that cause difficulty in treatment (diseases), patient backgrounds that cause difficulty in treatment (backgrounds), important clinical factors and important clinical strategies. Statistical comparisons were made between the groups. In the Likert scale, higher scores show a greater degree of difficulty.ResultsWe obtained responses from 439 and 397 specialists in the G and PC, respectively (response rates 26.6 and 24.1%). The overall scores for “diseases” and “backgrounds” were significantly higher in the G than those in the PC (P < 0.001 and P = 0.018). The top 10 items in the “backgrounds” and in the “important clinical strategies” were all matched between the groups. The overall score of the “important clinical factors” was not statistically different between the groups; however, “low nutrition,” “bedridden activities of daily living,” “living alone” and “frailty” were found only in the top 10 items of the G, and “financial problems” was found in those of the PC.ConclusionsGeriatricians and primary care physicians have many similarities and differences in their approaches to multimorbidity management. Therefore, there is an urgent need to establish a system in which they can share a common understanding to manage older patients with multimorbidity. Geriatr Gerontol Int 2023; 23: 628–638.

Published: July 2023

AbstractSustainability‐oriented collaboration, a heterogeneous set of formal interorganizational arrangements that vary considerably in size, membership, focus and functioning, but share the same interest in addressing sustainability challenges of public concern, is becoming a mainstay of corporate agenda setting. Yet, the more firms interact on social and environmental issues, the more the burdens and tensions of collaborating for sustainability become apparent. Research and practice increasingly question whether an alliance management capability (AMC) perspective can be adopted to explain variability in collaboration effectiveness. With the aim to investigate whether, and to what extent, existing sustainability‐oriented collaboration research integrates or challenges mainstream theory on AMC, we adopt a problematization method to unpack the root assumptions underlying the AMC construct. We find that self‐interest in economic value creation and capture, the need for homogeneity to favour knowledge accumulation and learning on alliance management, and predictable patterns of AMC deployment are consistently assumed by scholars to predict success in alliance management. Accordingly, we analyse AMC assumptions’ current integration in the study of sustainability‐oriented collaboration, conducting a systematic literature review on collaborative capabilities developed for, during and in response to sustainability challenges. In so doing, we identify what distinguishes sustainability‐oriented collaboration from mainstream strategic alliances and the related implications on the collaborative capabilities firms should develop and deploy when dealing with sustainability challenges. We elaborate on these and their implications for AMC constructs to provide a future research agenda, which integrates further theoretical perspectives and broadens the scope of existing ones.
cAMP responsive element modulator α promotes effector T cells in systemic autoimmune diseases
Authors: Carlsson Emil , Cowell‐McGlory Taylor , Hedrich Christian M. 
Published: July 2023

AbstractT lymphocytes play a crucial role in adaptive immunity. Dysregulation of T cell‐derived inflammatory cytokine expression and loss of self‐tolerance promote inflammation and tissue damage in several autoimmune/inflammatory diseases, including systemic lupus erythematosus (SLE) and psoriasis. The transcription factor cAMP responsive element modulator α (CREMα) plays a key role in the regulation of T cell homeostasis. Increased expression of CREMα is a hallmark of the T cell‐mediated inflammatory diseases SLE and psoriasis. Notably, CREMα regulates the expression of effector molecules through trans‐regulation and/or the co‐recruitment of epigenetic modifiers, including DNA methyltransferases (DNMT3a), histone‐methyltransferases (G9a) and histone acetyltransferases (p300). Thus, CREMα may be used as a biomarker for disease activity and/or target for future targeted therapeutic interventions.

AbstractPure and Eu2+‐activated fluoroborate BaGaBO3F2 was prepared using high‐temperature solid‐state reaction. BaGaBO3F2 is a wide band semiconductor with the indirect transition characteristic. The excitation and luminescence spectra of the phosphor were measured, and it was found that Eu2+‐activated BaGaBO3F2 exhibits a bright blue color under ultraviolet (UV) light. The narrow emission band peaked at 425 nm is attributed to the transitions of 4f65d→4f7(8S7/2), and the Stokes shift estimated for this phosphor sample is 3140 cm−1. The lifetime of the luminescence is also reported. The absolute quantum efficiency (QE) of the phosphor was evaluated, and it was found that the absolute QE decreases with increasing Eu2+ concentration. The phosphor shows an excellent quantum efficiency of 72.5% and a high thermal activation energy of 0.342 eV. The study concludes that Eu2+‐doped BaGaBO3F2 phosphor has promising luminescence application abilities and can be used as a blue‐emitting phosphor in a variety of applications.

AbstractUltrahigh‐temperature ceramics (UHTCs) exhibit remarkable hardness and resistance to oxidative ablation, making them suitable for use in hypersonic environments, such as hypersonic aircraft and space shuttles. However, their low fracture toughness limits their applications as engineering materials. In this study, zirconium diboride, an extremely hard and oxidation‐resistant UHTC, was sintered with high aspect ratio boron nitride nanotubes (BNNTs) to improve the fracture toughness of UHTC. Although the high aspect ratio BNNTs tend to become entangled and are inefficient in improving the fracture toughness of the composite, the use of plasma functionalization can effectively disperse the BNNTs in UHTC, resulting in the increase in the fracture toughness of the UHTC composite.
An examination of learning ecologies associated with the Holocaust: The role of social media
Authors: Manca Stefania , Raffaghelli Juliana Elisa 
Published: July 2023

AbstractBackgroundHolocaust memory and learning processes have become increasingly mediatised as a result of rapid technological advances. There is, however, little information available regarding how people learn about this topic informally through social media.ObjectivesThis paper explores how adult learners develop their learning ecologies by using social media to learn about the Holocaust informally.MethodsThe study uses a learning ecology perspective to analyse the interests, expectations and learning process of a group of adult learners (N = 276). An online survey tool was developed to collect information on the interests, expectations, and benefits of learning about Holocaust‐related topics among online users of four Italian Holocaust museums' social media profiles (Facebook, Twitter, Instagram and YouTube). Descriptive and inferential statistics were used to summarise the characteristics of the sample and to answer the research questions.Results and ConclusionsThe results show that most of the respondents are mostly women, with an average age of 50 and a higher level of education. In terms of interest and expectations, they are particularly interested in issues related to the intertwining of transnational and national memory. They also express a sense of civic responsibility with regard to the legacy of the Holocaust. Finally, components of the learning process show proactive behaviour and a preference for individual learning, while interaction with peers is considered less important.TakeawaysThere is an urgent need to understand how learners' preferences influence the development of learning ecologies and the types of content they are most likely to be exposed to as a result. It is also important for social media content providers to understand that learners are looking for quality resources and trustworthy content to further their education.
The influence of social media literacy on student engagement in online learning

AbstractBackgroundRecent years have seen the proliferation of online courses that have been initiated either in accordance with the natural rhythms of educational technology growths or in force majeure situations. This adds complexity to understanding the influence of potential factors on online student engagement.ObjectivesThe present study conducted an essential inspection to explore the relationship between student social media literacy and their engagement in online learning settings.MethodologyA sample of 1015 undergraduate students participated in this study and the partial least squares structural equation modelling (PLS‐SEM) was chosen for evaluating the research model. In addition, to provide more information on the prioritization of strategic actions, the importance‐performance map analysis (IPMA) was also performed.ResultsIn a two‐factor construct, social media literacy was found to have a significantly positive relationship with aspects of student engagement in the online learning environment. The influence of technical competence is still undeniable, but the effect of cognitive competence on online student engagement is more significant. In addition, appearing in the fourth quadrant (low performance ‐ high importance) in all IPMA presentations, the anticipatory reflection is the construct that should be prioritized for improvement to augment student engagement in online learning.
CEO prior uncertainty and pay–performance sensitivity
Authors: Lee Jiyoon 
Published: July 2023

AbstractA CEO's pay–performance sensitivity (PPS) is higher in the first year of their tenure than in the following years. I explain this finding with reference to chief executive officer (CEO) prior uncertainty: Because of information asymmetry and/or uncertainty about the quality of the match between a CEO and a firm, first‐year compensation is often arranged to depend largely on performance. Consistent with this explanation, CEOs with higher prior uncertainty exhibit higher first‐year PPS. Also, PPS is higher for outsider CEOs than insider CEOs. Among outsider CEOs, first‐year PPS is lower for former executives of large public firms. An insider CEO's service time in a firm before becoming the CEO reduces first‐year PPS.

AbstractAloe vera (Aloe barbadensis Miller) is employed as a food supplement containing mucopolysaccharides which contribute to a healthy diet. Aloe vera mucilage is usually obtained through an evaporation process. An alternative process to preserve polysaccharide properties is ultrafiltration (UF), which impedes degradation of the compound by temperature. This work analyses the effect of the UF process on the mechanical and rheological properties of Aloe vera considering the following variables: temperature (T), input feeding rate (V), and transmembrane pressure (ΔPTM). The permeate flux varies according to the operating conditions exhibiting non‐Newtonian effects. The determination of the mass transfer coefficient is based on the analogy of transport phenomena (heat transfer to mass transfer) in non‐Newtonian fluids to obtain the permeate flux. The results show that when the mucilage is fed as a diluted shear‐thinning fluid, the UF efficiency is positively affected. To describe the rheological behavior of the concentrated mucilage, the power law and the Bautista‐Manero‐Puig (BMP) models are used and compared. Results suggest that the BMP model represents better the experimental data of permeate flux as a function of filtrate concentration with respect to the experimentally measured permeate flux.Practical ApplicationsCurrently, the use of Aloe vera mucilage as encapsulating agents, thickeners, emulsifiers, and wall materials is highly appreciated by the food and pharmaceutical industry. This research shows that the concentrate obtained from Aloe vera mucilage by ultrafiltration (UF) preserves its rheological properties, unlike other thermal processes. Results represent an interesting and promising alternative to estimate the properties of Aloe vera using more realistic rheological models with promising applications in the food and pharmaceutical industry. The Aloe vera mucilage increases the health benefits using the mucilage in different concentrations in different industrial processes.

Published: July 2023

AbstractAimObstetrical guidelines were established in Japan in 2008, and obstetrical diagnoses and treatments were subsequently standardized nationally. We examined changes in the preterm birth rate (PTBR) and extremely preterm birth rate (EPTBR) following the introduction of such guidelines.MethodsInformation on 50 706 432 live births in Japan between 1979 and 2021, including Japanese reproductive medicine, the childbearing age of pregnant women, and the employment status of reproductive‐age women between 2007 and 2020, were obtained from the Japanese government and academic societies. Regression analysis was used to compare chronological changes nationally and those of eight Japanese regions. Regional and national average PTBRs and EPTBRs from 2007 to 2020 were compared by using a repeated measures analysis of variance.ResultsFrom 1979 to 2007, PTBRs and EPTBRs in Japan increased significantly. However, from 2008, the national PTBR and EPTBR decreased until 2020 (p < 0.001) and 2019 (p = 0.02), respectively. From 2007 to 2020, overall PTBR and EPTBR were 5.68% and 0.255%, respectively. A significant difference in the PTBR and EPTBR existed between the eight Japanese regions. During this period, the number of pregnancies using assisted reproductive technology increased from 19 595 to 60 381, pregnant women became older, the employment rate of those of reproductive age increased, and nonregular employment was 54%, which was 2.5 times higher than for men.ConclusionsIn Japan, after obstetrical guidelines were enacted in 2008, PTRBs decreased significantly even under the pressure of increasing preterm births. Countermeasures may be necessary for regions showing high PTBRs.

AbstractBackgroundThe relationship between the maximum lip‐closing force (LCF) and malocclusion has long been studied. Recently, a method to measure the ability to control directional LCF from eight directions (upper, lower, right, left and the four directions in between) during lip pursing was established.ObjectiveIt is considered important to evaluate the ability to control directional LCF. The aim of this study was to investigate the ability of skeletal class III patients to control directional LCF.MethodsFifteen skeletal class III patients (mandibular prognathism group) and 15 people with normal occlusion (normal occlusion group) were recruited. The maximum LCF and the accuracy rate (the ratio of the matched time in which the participant was able to keep the LCF in the target range over a total time of 6 s) were measured.ResultsThe maximum LCF was not significantly different between the mandibular prognathism group and the normal occlusion group. The accuracy rate in the mandibular prognathism group was significantly lower in all six directions than that in the individual normal occlusion group.ConclusionAs the accuracy rate in all six directions was significantly lower in the mandibular prognathism group than that in the normal occlusion group, occlusion and craniofacial morphology might influence lip function.

AbstractBackgroundTechnology, such as telehealth, is increasingly used to support home dialysis patients. The challenges patients and carers face when home dialysis nursing visits are provided via telehealth have yet to be explored.ObjectivesTo explore patients' and carers' perspectives as they transition to telehealth‐assisted home visits and identify the factors influencing their engagement in this modality.DesignA mixed‐methods approach, guideed by the behaviour change wheel using the capability, opportunity, motivation‐behaviour model to explore individual's perceptions of telehealth.PartcipantsHome dialysis patients and their carers.MeasuruementsSuveys and qualitative interviews.MethodsA mixed‐methods approach was undertaken, combining surveys and qualitative interviews. It was guided by the Behaviour Change Wheel using the Capability, Opportunity, Motivation‐ Behaviour model to explore individuals' perceptions of telehealth.ResultsThirty‐four surveys and 21 interviews were completed. Of 34 survey participants, 24 (70%) preferred face‐to‐face home visits and 23 (68%) had previously engaged in telehealth. The main perceived barrier identified in the surveys was knowledge of telehealth, but participants believed there were opportunities for them to use telehealth. Interview results revealed that the convenience and flexibility of telehealth were perceived as the main advantages of telehealth. However, challenges such as the ability to conduct virtual assessments and to communicate effectively between clinicians and patients were identified. Patients from non‐English speaking backgrounds and those with disabilities were particularly vulnerable because of the many barriers they faced. These challenges may further entrench the negative view regarding technology, as discussed by interview participants.ConclusionThis study suggested that a blended model combining telehealth and face‐to‐face services would allow patient choice and is important to facilitate equity of care, particularly for those patients who were unwilling or had difficulty adopting technology.
Inferred Social Expectations are Linked to Prosocial Effort in Teamwork in Japan but not in the United States1
Authors: Gherghel Claudia 
Published: July 2023

AbstractUnlike in Western cultures, where meeting others' expectations is considered incompatible with individual agency, social expectations tend to be internalized and congruent with the self in Eastern cultures, where meeting others' expectations has been shown to promote effort and satisfaction. However, considering cross‐cultural differences in mind‐reading, research has yet to clarify whether directly expressing social expectation has the same effects as inferring social expectation from others' messages. With the aim of disentangling the effects of expressed and inferred social expectation on prosocial behavior, two online studies employing teamwork scenarios, in which participants (donors) had the opportunity to help other people (targets) by putting effort into a common task (prosocial effort), were conducted in Japan and the United States. The strength of expressed social expectation was manipulated within subjects in Study 1 (N = 439) and between subjects in Study 2 (N = 560). The effect of expressed social expectation did not differ by culture, but inferred social expectation positively predicted prosocial effort only in Japan. The findings hint at the importance of mind‐reading and subjective perceptions of others' needs in Japan.
Crypto quanto and inverse options

Published: July 2023

AbstractOver 90% of exchange trading on crypto options has always been on the Deribit platform. This centralized crypto exchange only lists inverse products because they do not accept fiat currency. Likewise, other major crypto options platforms only list crypto–stablecoin trading pairs in so‐called direct options, which are similar to the standard crypto options listed by the CME except the US dollar is replaced by a stablecoin version. Until now a clear mathematical exposition of these products has been lacking. We discuss the sources of market incompleteness in direct and inverse options and compare their pricing and hedging characteristics. Then we discuss the useful applications of currency protected “quanto” direct and inverse options for fiat‐based traders and describe their pricing and hedging characteristics, all in the Black–Scholes setting.
Barred olivine chondrules in ordinary chondrites: Constraints on chondrule formation
Authors: Rubin Alan E. , Dunn Tasha L. , Garner Kyla , Cecchi Malena , Hernandez Mitchell 
Published: July 2023

AbstractIn general, barred olivine (BO) chondrules formed from completely melted precursors. Among BO chondrules in unequilibrated ordinary chondrites, there are significant positive correlations among chondrule diameter, bar thickness, and rim thickness. In the nebula, smaller BO precursor droplets cooled faster than larger droplets (due to their higher surface area/volume ratios) and grew thinner bars and rims. There is a bimodal distribution in the olivine FeO content in BO chondrules, with a hiatus between 11 and 19 wt% FeO. The ratio of (FeO rich)/(FeO poor) BO chondrules decreases from 12.0 in H to 1.6 in L to 1.3 in LL. This is the opposite of the case for porphyritic chondrules: the mean (FeO rich)/(FeO poor) modal ratio increases from 0.8 in H to 1.8 in L to 2.8 in LL. During H chondrite agglomeration, most precursor dustballs were small with low bulk FeO/(FeO + MgO) ratios and moderately high melting temperatures. The energy available for chondrule melting from flash heating was relatively low, capable of completely melting many ferroan dusty precursors (to form FeO‐rich BO chondrules), but incapable of completely melting many magnesian dusty precursors (to form FeO‐poor BO chondrules). When L and LL chondrites agglomerated somewhat later, significant proportions of precursor dustballs were relatively large and had moderately high bulk FeO/(FeO + MgO) ratios. The energy available from flash heating was higher, capable of completely melting higher proportions of magnesian dusty precursors to form FeO‐poor BO chondrules. These differences may have resulted from an increase in the amplitude of lightning discharges in the nebula caused by enhanced charge separation.
