Abstract

Objective
To analyze the temporal trends in the global and regional burden of male infertility from 1990 to 2021, explore influencing factors, assess the relationship with socio-demographic development, analyze health inequalities, and forecast future trends.
Methods
Using epidemiological data on male infertility from the Global Burden of Disease (GBD) Study database for 1990–2021, we calculated prevalence, disability-adjusted life years (DALYs), and other indicators. Joinpoint regression, age-period-cohort analysis, and decomposition analysis were used to examine temporal trends and influencing factors. Data envelopment analysis was used to assess the relationship between male infertility and the Socio-Demographic Index (SDI). The Slope Index of Inequality (SII) and Concentration Index (CI) were used to analyze health inequalities. ARIMA and Bayesian APC models were used to forecast prevalence from 2022 to 2036.
Results
The global crude prevalence rate of male infertility was 1389.1 per 100,000 in 2021, and the age-standardized prevalence rate was 1354.8 per 100,000. Eastern Europe had the highest prevalence, while Australasia had the lowest. South Asia had the highest DALYs. Overall, prevalence showed a decreasing-then-increasing trend from 1990 to 2021, with the fastest growth occurring from 2010 to 2014. The trend of DALY changes is basically consistent with the incidence rate, with a rapid increase after 2010. Infertility risk increased with age until 37.5 years and then decreased, beginning to decline after 1994. Population growth was the main driver of increasing prevalence. The increase in DALY rates is also mainly driven by population growth, contributing up to 68.06% globally, and the impact of population aging in high SDI regions on DALY rates initially shows a significant negative effect. As SDI increased, the DALY rate generally decreased, but there was room for improvement in some countries. Inequality between high and low SDI regions increased. Prevalence was predicted to rise in the future.
Conclusions
The global burden of male infertility is increasing overall, with lower prevalence in high SDI regions and higher DALYs in low SDI regions. Attention should be paid to rapidly growing populations, improving reproductive health services and equitable access. Screening and interventions for high-risk populations should be strengthened to curb the rising prevalence trend.
The Role Of Fomo In The Impact Of Religious Attitude And Hedonic Consumption Among Turkish Muslim Consumers
Authors: ATA SERHAT , KARACA ŞÜKRAN , BARAN ZÜLEYHAN 
Published: February 2025

Abstract

This study explores the intricate dynamics between religious attitudes and hedonic consumption behaviors, with Fear of Missing Out (FoMO) as a pivotal mediator, focusing on Turkish Muslim consumers. By examining data from 562 participants across Türkiye, this research unveils how religious principles, while traditionally curbing materialism, paradoxically foster specific hedonic consumption motivations when mediated by FoMO. Utilizing advanced structural equation modeling, the findings underscore FoMO's transformative role in linking religious attitudes to adventure and gratification-based, role-based, value-based, and social-based shopping behaviors. The strongest effects are observed in socialized and adventure-oriented consumption, reflecting a tension between spiritual adherence and contemporary consumerist pressures. This study not only expands the theoretical discourse on religious consumer behavior but also offers a groundbreaking perspective on how psychological constructs like FoMO reshape traditional paradigms. These learnings offer implementable strategies for culturally sensitive marketing practices for Muslim consumers, which maintains the tension between the spirit of authenticity and contemporary consumerism.

Published: February 2025

ABSTRACT

The discharge of untreated wastewater into water bodies impacts water quality, ecosystems, treatment costs, and water security. Existing investment strategies in water supply and wastewater treatment often lack coordination, particularly among different utilities. This study evaluated the trade-offs between investment costs and economic benefits of sanitation investments in the Jundiaí River Basin, São Paulo State, Brazil. We analyzed economic trade-offs using various investment timelines to achieve different levels of wastewater contaminant removal. Results indicated that delaying investments lowers costs but also postpones and diminishes benefits, such as reduced water treatment costs, energy savings and potential revenue generated by selling water reuse. Postponed sanitation investments show a decreasing benefit/investment ratio, while wastewater treatment and reuse provide significant revenue. These findings underscore the importance of integrating water resources management with sanitation planning to enhance water security and align with circular economy principles. Policymakers should prioritize collaborative frameworks to distribute costs and benefits equitably, ensuring sustainable sanitation practices and contributing to the achievement of Sustainable Development Goals 6.2 and 6.3.

Authors: JATIN CHAUHAN  , RAJESH KUMAR THAKUR  , BIPIN KUMAR YADAV  , DIKSHA GUPTA  
Published: February 2025

The buccal fat represents a specialized and organized adipose tissue that maintains its volume and stability over long periods of time and serves as a well-vascularized, easily accessible local flap for reconstructive procedures such as the enhancement of root coverage in severe recession defects, thereby augmenting the dimensions of keratinized mucosa. Areas with Miller's Class III and IV gingival recessions are not considered amenable to intervention utilizing surgical root coverage methodologies because of the poor prognosis with existing techniques. In this case report, a pedicled buccal fat pad (PBFP) was used as a subepithelial grafting technique for root coverage in a maxillary posterior tooth exhibiting a Class III gingival recession defect coupled with a deficiency of keratinized gingiva. At a 3-month follow-up, this approach demonstrated effective root coverage, increased keratinized tissue, and improved patient comfort, as documented, with no notable complications.
Collabographies: Tracing shared processes between performer and composer
Authors: Petra Valtellina  
Published: February 2025

This research aims to address the question of how performer-composer collaborations can effectively generate a jointly composed flute piece. By examining two collaborative processes undertaken over the past year with different composers, this research seeks to identify factors that facilitated successful collaborations and those that posed challenges. Through comparative analysis, the goal is to identify strategies and approaches that could inform and improve future collaborations of this nature. This study ponders the contrast in the background of the two composers involved and the different experiments in role balance. As the performer, I serve as the common thread between these collaborations; variations in the outcomes result from interpersonal dynamics and the composers' differing levels of familiarity with the flute. The methodology employed aligns with the principles of Action Research, with iterative cycles of feedback, reflection, and adjustments during the collaborations, prioritising the process over the final product.
Outcomes of this investigation include that complementary skills, clear expectations, transparent and unfiltered communication, external deadlines, defined final goals, and narrower guidelines might enhance collaborative engagement, improving satisfaction and musical products.
Following the introduction, which addresses the motivations underlying this study, Chapters 1 and 2 will contextualise the topic of collaboration through a literature review and present the chosen methodology. Chapter 3 will delve into a comprehensive overview of the two collaborations, while Chapter 4 will propose a comparative analysis of these processes and report the limitations of this study. Conclusions will follow.

Priority moral and ethical qualities in Russia and China: a comparative analysis based on empirical research
Authors: Wan Guangfu , Glebova Polina Alexandrovna 
Published: February 2025

The subject of the study is the peculiarities of perception and prioritization of moral and ethical values among Russians and Chinese based on an associative experiment, the object of the study is moral and ethical values in Russia and China. The authors consider in detail such aspects as the key differences in the moral and ethical values of the two cultures, the influence of historical and philosophical traditions on the formation of ethical norms. Special attention is paid to such phenomena as globalization, technological progress, the spread of individualistic values, as well as subsequent changes in moral and ethical guidelines in both China and Russia. The authors note the importance of preserving traditional values and passing them on to the next generations. The directed associative experiment conducted by the authors helps to fully consider the object and subject of the study, which helps to identify the most significant moral and ethical categories in the minds of Russians and Chinese. The research methodology is determined by the set goal and is complex in nature: general scientific methods of analysis and synthesis, a descriptive method with methods of observation and generalization, a comparative method and a method of socio-cultural analysis were used, and a linguistic associative experiment was conducted. The scientific novelty of the study lies in the cross-cultural comparison of associative ideas about morality, which makes it possible to identify social and historical factors influencing the formation of morality and ethics in the two countries. The conducted associative testing revealed key differences and similarities in the perception of the main moral and ethical categories by Chinese and Russian societies. Using the results and statistics of the experiment, the authors came to the conclusion about the profound influence of Confucianism and collectivist culture on the worldview of the Chinese, as well as on the connection of Christianity, Russian art and the hierarchy in society established in the earlier period of Russian history with modern value orientations of Russians. At the moment, the number of scientific papers examining the difference between Chinese and Russian mentalities using an integrated and multifaceted approach using practical methods seems to be very limited. The results obtained can be useful for further research in the field of intercultural communication and international relations.
Allocating Limited Resources and Learning Flight Energy Consumption for Advanced Air Mobility
Authors: Samiei Arezoo , Selje Robert , Sun Liang 
Published: February 2025

This paper addresses the problem of efficiently managing clean-energy aerial vehicles for advanced air mobility (AAM) in a distributed manner. A concept of operation for AAM vehicles is considered to deliver packages for a number of customers at different locations. The objective of the problem is to minimize the overall energy consumption of all AAM vehicles. A feed-forward neural network (FFNN) is proposed to predict the fight energy consumption of a delivery drone, whose flight data were used to train the neural network. To optimize the allocation of AAM vehicles to service stations (e.g., for charging and maintenance) with limited service bays, a distributed limited resource allocation algorithm (DLRAA) is proposed based on the Hungarian method. DLRAA was compared with a mixed integer linear programming (MILP) solver based on the average run time and average cost in 1000 simulation runs. The results show that the proposed FFNN produced an accurate prediction given noisy flight data, the proposed DLRAA generates allocation that satisfies the given constraints efficiently, and DLRAA outperforms MILP based on average cost in all testing cases. DLRAA outperforms MILP based on the average run time when the number of charging stations is less than 30 and the number of drones is less than 160.
Parametric Model Order Reduction for Structural Optimization of Fiber Composite Structures
Authors: Sanmugadas Varakini , Agarwal Mayank , Borwankar Pranav , Kapania Rakesh K. 
Published: February 2025

This research addresses the inherent computational demand of metaheuristic optimization techniques by developing a novel optimization framework that uses parametric model order reduction (PMOR). The improvement in efficiency is demonstrated using the buckling optimization of variable-angle tow (VAT) composite panels, as navigating the complex design space of VAT composite structures with global optimization techniques requires a substantial number of function evaluations. A new affine summation relationship conducive to PMOR was derived for its finite element stiffness matrix using the concept of lamination parameters and material invariant matrices, and principal component analysis (PCA) was used to extract the reduced basis vectors. Particle swarm optimization was conducted using a full-order model (FOM) and a reduced-order model. PMOR-based optimization exhibited a 0.55% relative error in the optimal objective value compared to the FOM analysis and exhibited a similar convergence history. It was observed that the optimization time was reduced by 93% by the novel affine decomposition alone, but PMOR achieved a significant reduction of 99.8% in memory requirements compared to the FOM. As the affine-decomposition-based assembly of the FOM is not feasible for large problems, PMOR functions as an enabling tool for leveraging the improvement offered by it.
Aero-Optical Distortions of a Turbulent Boundary Layer at Back-Looking Viewing Angles
Authors: Gordeyev Stanislav , Butler Luke 
Published: February 2025

This paper presents the results of wavefront measurements of aero-optical effects due to a subsonic turbulent boundary layer at various laser beam viewing angles relative to the tunnel wall. Data were taken at Mach numbers of 0.3, 0.4, and 0.5 at back-looking angles ranging from 90 to 170 deg. A multipoint spectral cross-correlation technique was used to minimize the corrupting effects of the mechanical vibrations on the aero-optical spectra. A scaling of the aero-optical spectra as a function of the viewing angle was developed and discussed. Both the apparent optical convective speeds and the overall values of aero-optical distortions were extracted from data. Angular dependence of the aero-optical distortions was computed and found to agree with the isotropic model within a few percent. Two new models, accounting for the presence of the large-scale structures and for the spatial growth of the boundary layer, were proposed and discussed.
