Abstract
Purpose
To examine the prevalence of female sexual dysfunction (FSD), male erectile dysfunction (ED), and the prevalence and correlates of sexual health discussions between early-onset CRC survivors and their health care providers.

Methods
An online, cross-sectional survey was administered in partnership with a national CRC advocacy organization. Respondents (n = 234; diagnosed < 50 years, 6–36 months from diagnosis/relapse) were colon (36.8%) and rectal (63.3%) cancer survivors (62.5% male). The Female Sexual Function Index (FSFI-6) was used to measure FSD, and the International Index of Erectile Function (IIEF-5) was used to measure ED. Survivors reported whether a doctor communicated with them about sexual issues during/after treatment.

Results
Among females (n = 87), 81.6% had FSD (mean FSFI-6 score = 14.3 [SD±6.1]). Among males (n = 145), 94.5% had ED (mean IIEF-5 score = 13.6 [SD±3.4]). Overall, 59.4% of males and 45.4% of females reported a sexual health discussion. Among the total sample, older age of diagnosis and relapse were significantly associated with reporting a discussion, while female sex was negatively associated with reporting a sexual health discussion. Among males, older age at diagnosis and relapse, and among females, older age of diagnosis, were significantly associated with reporting a sexual health discussion.

Conclusion
The prevalence of FSD and ED were high (8 in 10 females reporting FSD, almost all males reporting ED), while reported rates of sexual health discussion were suboptimal (half reported discussion). Interventions to increase CRC provider awareness of patients at risk for not being counseled are needed to optimize long-term health outcomes.
Skew differential Goppa codes and their application to Mceliece cryptosystem
Authors: Gómez-Torrecillas José , Lobillo F. J. , Navarro Gabriel 
Published: August 2023

AbstractA class of linear codes that extends classical Goppa codes to a non-commutative context is defined. An efficient decoding algorithm, based on the solution of a non-commutative key equation, is designed. We show how the parameters of these codes, when the alphabet is a finite field, may be adjusted to propose a McEliece-type cryptosystem.

AbstractThis study examines the factors that affect pre-service and in-service teachers’ intention to use Mobile Augmented Reality (MAR) in their teaching through the proposed Mobile Augmented Reality Acceptance Model (MARAM). The MARAM builds on the existing Technology Acceptance Model (TAM) to incorporate four other components namely perceived relative advantage, perceived enjoyment, facilitating conditions, and mobile self-efficacy. In addition, this study investigates the validity of the MARAM. Data were collected from 137 pre-service and 169 in-service teachers who completed a questionnaire after having developed their own MAR applications during an undergraduate university course and a training seminar, respectively. Structural Equation Model (SEM) analysis was conducted separately for each group, as well as for both samples together. We also conducted a multi-group analysis to examine differences across the two samples. The results for both samples together (N = 306), showed that intention was affected by attitude, perceived usefulness and facilitating conditions. In turn, attitude was affected by perceived enjoyment and perceived usefulness. Perceived usefulness was affected by perceived enjoyment and perceived relative advantage. Perceived ease of use was affected by mobile self-efficacy and facilitating conditions. However, perceived ease of use did not affect perceived usefulness or attitude. A multi-group analysis conducted on the sample of pre-service and in-service teachers produced similar results, with minor differentiations. These results have implications for the use of MAR in research and schools, as well as technology acceptance models in education.

Published: August 2023

AbstractAvocado orchards (Persea americana) in Mexico are constantly being expanded to meet the increasing demand for the fruit in the national and international markets. The land-use change (LUC) caused by this expansion has numerous negative impacts, including greenhouse gas (GHG) emissions due to the loss of forest cover and the burning of pruning residues. To generate a comprehensive evaluation of this complex environmental issue, we calculate emissions from LUC and from residue burning between 1974 and 2017 at a local scale (1:20,000), and the energy potential of pruning residues was estimated as an alternative to revalue a waste product and mitigate the negative impacts of avocado cultivation. Our results show that land-use conversions emitted 390.5 GgCO2, of which 91% came from conversions to avocado orchards. Emissions of GHG from biomass burning amounted to an additional 20.68 GgCO2e released per year. Given that around 12,600 tons of dry avocado pruning residues are generated annually in the study region, their use for energy generation could replace 240 TJ/year of fossil fuels in rural industries and could mitigate around 31 GgCO2e per year. This study provides decision-makers with a concrete example of how to establish multiple-impact strategies at local scales.

Published: August 2023

AbstractUrban waterfronts have evolved into vibrant centres of recreation, tourism, and economic activities, becoming focal points for social, cultural, and religious gatherings in modern cities. The historical development of riverfronts sought to elevate the economic status and image of neighbouring cities during the industrial era. However, with the growing emphasis on riverfront revitalization projects in recent times, it has become imperative to prioritize environmental sustainability and ecological considerations in the planning and execution of these initiatives. This paper delves into the revitalization plans of the Sabarmati and Patna riverfronts in India, undertaking a comparative assessment of their development strategies and challenges encountered in ecological preservation. The study seeks to explore the interplay between the river and environmental concerns and analyse the positive impacts of ecological improvements on the social and economic dimensions of these urban waterfronts. Additionally, the research scrutinizes the alignment of these various aspects with the United Nations' Sustainable Development Goals, presenting an integrated approach towards fostering holistic and sustainable urban riverfront development. The study on riverfront development projects revealed that successful projects prioritize social inclusivity, economic vitality, and environmental sustainability, contributing to the long-term success and well-being of both communities and ecosystems. The research demonstrates the potential for holistic and sustainable urban development through riverfront revitalization, offering valuable insights and case studies for future urban redevelopment projects.
Toward fixing a framework for conformal cyclic cosmology
Authors: Markwell Oliver , Stevens Chris 
Published: August 2023

AbstractConformal Cyclic Cosmology (CCC) is a cyclic model of the universe put forward by Sir Roger Penrose (Cycles of Time: An Extraordinary New View of the Universe, Random House, Manhattan, 2010). A conformal invariance assumption in the neighbourhood of the crossover region between cycles (which Penrose calls aeons) allows successive space-times to be related by a conformal rescaling. A major open problem is how to choose the conformal factor in a unique way, and is a fundamental hurdle to further study. Proposals have been put forward by Newman (Gen Relativ Gravit 46(5):1–13, 2014), Tod (Gen Relativ Gravit 47(3):1–13, 2015) and Nurowski (Class Quantum Gravity 38(14):145004, 2021), but they disagree in one way or another with Penrose’s original assumptions as well as each other. In this paper we compare these different models in detail and rule out certain choices for the conformal factor that have been put forward by Penrose. We extend the results of Newman and fix inconsistencies that arose in his calculations. A new class of solutions are put forward which agree with Penrose’s assumptions exactly so long as a certain additional relation is satisfied.

AbstractKnowledge of thermodynamic properties of aqueous solutions of CO2 is crucial for various applications including climate science, carbon capture, utilisation and storage (CCUS), and seawater desalination. However, there is a lack of reliable experimental data, and the equation of state (EOS) predictions are not reliable, particularly for sound speeds in low CO2 concentrations typical of water resources. For this reason, we have measured speeds of sound in three different aqueous solutions containing CO2. We report speeds of sound in the single-phase liquid region for binary mixtures of water and CO2 for mole fractions of CO2 of 0.0118, 0.0066 and 0.0015 at temperatures from 273.15 K to 313.15 K and at pressures up to 50 MPa, measured using a dual-path pulse-echo apparatus. The relative standard uncertainties of the sound speeds are 0.05 %, 0.03 % and 0.01 % at 0.0118, 0.0066 and 0.0015 CO2 mole fractions, respectively. The change in sound speeds as functions of composition, pressure and temperature are analysed in this study. We find that dissolution of CO2 in water increases its sound speeds at all conditions, with the greatest increase occurring at the highest mole fractions of CO2. Our sound speed data agree well with the limited available experimental data in the literature but deviate from the EOS-CG of Gernert and Span by up to 7 % at the lowest temperatures, highest pressures, and highest CO2 mole fraction. The new low-uncertainty sound speed data presented in this work could provide a basis for development of an improved EOS and in establishing reliable predictions of the change in thermodynamic properties of seawater-like mixtures due to absorption of CO2 gas.
The citrus flavonoid “Nobiletin” impedes STZ-induced Alzheimer’s disease in a mouse model through regulating autophagy mastered by SIRT1/FoxO3a mechanism

Published: August 2023

AbstractThe prominence of autophagy in the modulation of neurodegenerative disorders has sparked interest to investigate its stimulation in Alzheimer's disease (AD). Nobiletin possesses several bioactivities such as anti-inflammation, antioxidation, and neuroprotection. Consequently, the study's aim was to inspect the possible neurotherapeutic impact of Nobiletin in damping AD through autophagy regulation. Mice were randomly assigned into: Group I which received DMSO, Groups II, III, and IV obtained STZ (3 mg/kg) intracerebroventricularly once with Nobiletin (50 mg/kg/day; i.p.) in Group III and Nobiletin with EX-527 (2 mg/kg, i.p.) in Group IV. Interestingly, Nobiletin ameliorated STZ-induced AD through enhancing the motor performance and repressing memory defects. Moreover, Nobiletin de-escalated hippocampal acetylcholinesterase (AChE) activity and enhanced acetylcholine level while halting BACE1 and amyloid-β levels. Meanwhile, Nobiletin stimulated the autophagy process through activating the SIRT1/FoxO3a, LC3B-II, and ATG7 pathway. Additionally, Nobiletin inhibited Akt pathway and controlled the level of NF-κB and TNF-α. Nobiletin amended the oxidative stress through enhancing GSH and cutting down MDA levels. However, EX527, SIRT1 inhibitor, counteracted the neurotherapeutic effects of Nobiletin. Therefore, the present study provides a strong verification for the therapeutic influence of Nobiletin in AD. This outcome may be assigned to autophagy stimulation through SIRT1/FoxO3a, inhibiting AChE activity, reducing neuroinflammation and oxidative stress.

The Role of Mobile Money Innovations in the Effect of Inequality on Poverty and Severity of Poverty in Sub-Saharan Africa
Authors: Asongu Simplice A. , le Roux Sara 
Published: August 2023

AbstractThis study investigates the role of mobile money innovations in the incidence of income inequality on poverty and severity of poverty in 42 sub-Saharan African countries over the period 1980 to 2019. Mobile money innovations are understood as the mobile used to send money and the mobile used to pay bills online while income inequality is measured with the Gini index. Poverty is measured as the poverty headcount ratio while the severity of poverty is generated as the squared of the poverty gap index. The empirical evidence is based on interactive Quantile regressions. The following main findings are established. (i) Income inequality unconditionally reduces poverty and the severity of poverty though the significance is not throughout the conditional distributions of poverty and the severity of poverty. (ii) Mobile money innovations significantly moderate the positive incidence of income inequality on poverty and the severity of poverty in some quantiles. (iii) Positive net effects are apparent exclusively in the poverty regressions. (iv) Given the negative conditional effects, policy thresholds or minimum mobile money innovation levels needed to completely nullify the positive incidence of income inequality on poverty are provided: 27.666 (% age 15 +) and 24.000 (% age 15 +) of the mobile used to send money in the 50th and 75th quantiles, respectively and 16.272 (% age 15 +) and 13.666 (% age 15 +) of the mobile used to pay bills online in the 10th and 50th quantiles, respectively. Policy implications are discussed with respect of SDG1 on poverty reduction and SDG10 on inequality mitigation.

Published: August 2023

AbstractIn this paper, the electrical response of a carbon black polylactic acid 3D printed polymer is characterised in detail by a combination of advanced experimental techniques at different scale lengths. The electrical properties as a function of the temperature become repeatable after the second heating cycle, exhibiting different trends as a function of the printing parameters. Joule heating and oven-heating techniques have been compared, showing the advantages of the Joule heating method to maintain electrical conductivity due to the lower thermal inertia. Small-Angle X-Ray Scattering has been employed to discern the underlying physics, showing the crucial role of crystallinity, filler dispersion and carbon black aggregates to form an effective segregated conductive network. This investigation provides guidelines to produce 3D-printed devices with a reliable electrical response and the governing equations to operate them with sufficient accuracy for engineering applications.

Published: August 2023

AbstractThe adequate preparation of future teachers of mathematics is critical, requiring sufficient opportunities to develop both pedagogical skill and content knowledge. Yet, despite new recommendations for mathematics teacher preparation, we know little about the landscape of course-based learning opportunities in US elementary teacher education programs. To what extent do US elementary teacher education programs meet the Standards for Preparing Teachers of Mathematics outlined by the Association of Mathematics Teacher Educators (AMTE) for mathematics content and methods courses? Based on an a priori power analysis, we gathered a random sample of 291 higher education institutions. Within these institutions, we analyzed 736 programs, including Bachelor’s, Master’s, and Credential programs. We found that overwhelmingly US elementary teacher education programs do not meet the aspirations outlined in the AMTE standards, with Master’s and Credential programs and those covering all elementary grades particularly falling short. Potential explanations for these challenges and implications for teacher education program design are discussed.
Relationships Between Meaning in Life and Positive and Negative Spirituality in a Field Setting in Japan
Authors: Takano Ryota , Taoka Daiki 
Published: August 2023

AbstractThis study examined the relationships between positive/negative spirituality and meaning in life at two religious sites in Japan. Participants reported greater sadness and less meaning in life at Koyasan Okunoin, a temple with graves surrounded by nature, than at Nachi Kumano Taisha, a shrine with a waterfall. However, greater feelings of happiness protected meaning in life in the presence of sadness at Koyasan. Additionally, participants who felt a sense of awe reported greater meaning in life through self-liberation, regardless of the sites. The results provide new insights into meaning in life from the two sides of spirituality.
Properties of cobalt-doped SrTiO3 derived from two methods: the modified Pechini method and the citrate combustion method
Authors: Mizera Adrian , Drożdż Ewa 
Published: August 2023

AbstractTwo wet-synthesis methods: citrate-combustion and modified (with PVA addition) Pechini synthesis were used to obtain Co-doped strontium titanate with assumed chemical compositions of SrTi1−xCoxO3 (where x = 0.02; 0.06; 0.10). All samples were calcined at 900 °C and sintered at 1200 °C, with PVA series being also calcined at 700 and 800 °C, since TG measurements indicated for this method materials lower minimal calcination temperature than for the citrate-combustion series materials. In general, the modified Pechini approach lowers calcination temperature of materials (up to 200 °C) and produces more structurally homogeneous materials than in the case of the citrate-combustion methods. However, the HT XRD measurements reveal the presence of extra cobalt oxide phases in pva_STO_xCo materials that were not visible using conventional XRD measurements. The presence of cobalt oxide has been confirmed for both series of materials based on TPR tests. Moreover, these measurements indicate the incorporation of some amount of cobalt into the perovskite structure. The fact of substituting titanium with cobalt in SrTiO3 structure seems to be confirmed by the results of XAS studies. Additionally, XAS results allowed us to state that Co2+/Co3+ ratio fell as cobalt loading increased in the materials. The examination of SrTiO3 lattice parameter changes for sintered samples is consistent with the findings of the XAS tests and indicates that cobalt adopts +2 oxidation state in the case of the material with the lowest Co content, and the share of Co3+ increases with the growth of the Co amount introduced into the system.
Maternal Age at First Birth and Parental Support: Evidence From the UK Millennium Cohort Study
Authors: Goisis Alice 
Published: August 2023

AbstractUsing nationally representative data from the UK Millennium Cohort Study (n = 7396), we investigate whether the mother’s age at first birth is associated with the level of support she receives from her parents around the time of birth. We apply latent class analysis to construct a summary measure of five dimensions of parental support (contact with the mother, contact with the father, childcare, monetary transfers and financial support for buying essentials). The results show that parental support is negatively associated with maternal age at first birth, with older mothers being less likely than younger mothers to receive parental support. Adjustment for maternal socio-demographic characteristics and parental age partially attenuates the association. Given that parental support is positively associated with adult children’s well-being, labour force participation, and fertility the results suggest that integrating parental support into work investigating the causes and consequences of the timing of first births has the potential to enrich and expand our understanding of the costs and benefits of delaying childbearing towards older parental ages.
Developing SEP65: A Census-Derived Index of Socio-Economic Position Specifically for the Older Population in Aotearoa New Zealand
Authors: Exeter Daniel J. , Healey Olivia , Colbert Jessie , Shackleton Nichola 
Published: August 2023

AbstractBackgroundGlobally, societies are ageing as life expectancy increases and fertility rates decline. Many studies exploring associations between socioeconomic position (SEP) and health outcomes among the older population use conventional working-age measures of SEP (education, occupation, and income) or an area-based deprivation index.MethodsMicrodata from the 2013 New Zealand Census was used to create a new measure of socioeconomic position specifically for the population aged ≥65 years (SEP65), using information about housing tenure, wealth, and receiving government benefits. We dichotomised variables representing income, assets, and housing tenure to apportion 489,264 older people in our analytic sample into low, medium and high levels of SEP. A multivariable logistic regression was used to investigate the relationship between smoking and SEP65, controlling for age, sex, ethnicity and area-level deprivation.ResultsWe report inequities between European, Māori and Pacific populations, which increase with age. We found an inverse relationship between the odds of smoking and levels of SEP65. Moreover, we further validated the SEP65 measure against the New Zealand Index of Deprivation (NZDep2013).At the third SPINE20 summit 2022 which took place in Bali, Indonesia, in August 2022, 17 associations endorsed its recommendations.ConclusionUsing an age-specific measure of SEP for the older population will aid policymakers in the appropriate allocation of resources according to need more effectively than working-age indicators.
On simulation of continuous determinantal point processes
Authors: Lavancier Frédéric , Rubak Ege 
Published: August 2023

AbstractWe review how to simulate continuous determinantal point processes (DPPs) and improve the current simulation algorithms in several important special cases as well as detail how certain types of conditional simulation can be carried out. Importantly we show how to speed up the simulation of the widely used Fourier based projection DPPs, which arise as approximations of more general DPPs. The algorithms are implemented and published as open source software.
