Association between TV and/or video time and nocturia in adults: An analysis of the National Health and Nutrition Examination Survey.

This study aimed to examine the correlation between television (TV) and/or video viewing time and the occurrence of nocturia in adults. An analysis of data from the National Health and Nutrition Examination Survey for 2011-2016 was conducted, involving 13 294 adults aged 20 and older. The main outcome was specified as nocturia, which refers to the requirement of urinating two or more times during the night. Initially, baseline characteristics were contrasted between individuals with and without nocturia. The effects of TV and/or video viewing time on nocturia were further explored using multivariable logistic regression models. To acknowledge the variation in baseline data regarding the prevalence of nocturia, subgroup analyses were performed. Adjusted multivariate analysis revealed that individuals in the group with the longest TV and/or video viewing time had a significantly 48% higher risk of experiencing nocturia compared to those with the shortest TV and/or video viewing time. The results of subgroup analyses revealed no significant differences in the interaction tests between TV and/or video viewing time and nocturia. Our research showed that individuals who spent 5 or more hours a day watching TV and/or videos were significantly more likely to develop nocturia.

A meta-analysis of antecedents and consequences of trust in the sharing economy

PurposeTrust plays a crucial role in overcoming uncertainty and reducing risks. Uncovering the trust mechanism in the sharing economy may enable sharing platforms to design more effective marketing strategies. However, existing studies have inconsistent conclusions on the trust mechanism in the sharing economy. Therefore, this study aims to investigate the antecedents and consequences of different dimensions of trust (trust in platform and trust in peers) in the sharing economy.Design/methodology/approachFirst, we conducted a meta-analysis of 57 related articles. We tested 13 antecedents of trust in platform (e.g. economic benefits, enjoyment, and information quality) and eight antecedents of trust in peers (e.g. offline service quality and providers’ reputation), as well as their consequences. Then, we conducted subgroup analyses to test the moderating effects of economic development level (Developed vs Developing), gender (Female-dominant vs Male-dominant), platform type (Accommodation vs Transportation), role type (Obtainers vs Providers), and uncertainty avoidance (Strong vs Weak).FindingsThe results confirm that all antecedents and consequences significantly affect trust in platform or peers to varying degrees. Moreover, trust in platform greatly enhances trust in peers. Besides, the results of the moderating effect analyses demonstrate the variability of antecedents and consequences of trust under different subgroups.Originality/valueThis paper provides a clear and holistic view of the trust mechanism in the sharing economy from an object-based trust perspective. The findings may offer insights into trust-building in the sharing economy.

A new hybrid steel–timber rocking seismic force resisting system equipped with U-shaped fuse connections

This paper introduces a new low-damage hybrid steel–timber rocking braced frame with self-centring capability and proposes a design methodology in the framework of Canadian design standards. This system consists of a gravity load-resisting timber frame and a steel concentrically braced frame acting as the lateral load-resisting system that is connected using U-shaped steel fuses. The self-centring capability is achieved by post-tensioning strands and rocking bases within the lateral load-resisting system. The system, along with its components, is first introduced. The proposed design method and system performance objectives are then presented. The seismic performance of the system and the proposed design procedure are validated through numerical analyses considering the interaction between the lateral and gravity load-resisting systems. The results of dynamic analyses confirm the enhanced seismic performance of the proposed hybrid system with almost no residual deformations after the earthquake. Moreover, the proposed design guidelines can accurately predict the system’s seismic response and demands imposed on the members.

A Study on the Results of Risk Analyses Applying the Concept of Rock Mass Stand-Up Time for Underground Mining Sites

Throughout all the countries in the world, including Vietnam, nations with well-established mining industries have undertaken extensive research on the stability of rock masses when constructing underground tunnels in varied geological conditions. The present study aims to provide a comprehensive overview of the risk assessment related to rock masses during the construction of pit lines in mining operations. Consequently, the standing time of unsupported tunnels is assessed based on different values of the strength index and deformation characteristics of the rock mass. The objective was to perform both experimental and theoretical investigations to analyse how the stand-up time of rock masses surrounding a tunnel affects the unsupported span. The analyses were based on considering the rock parameters, including strain modulus; geological strength index; and allowable displacement values, and consideration of hereditary creep properties. By examining tunnels excavated in rock strata, it was concluded that varying geological strength index values resulted in distinct creep behaviour in the surrounding rock masses. Thus, it was reasonable to compute the unsupported span and stand-up time of tunnels. The research revealed that permissible displacements are significantly influenced by the types of rock materials surrounding the tunnel structure. Recognising the significance of time, the authors introduce a more practical interpretation and evaluation of the stability of rock masses, thus enhancing the precision of commonly available models.

The Impacts of Abattoir Wastes on Soil Quality at Ukwunwangwu, Uturu, Abia State, Nigeria

This study investigated the impact of abattoir waste on the soil quality in Ukwunwangwu, Uturu, Abia State. The aim of this study was to assess the impact of abattoir wastes on soil quality at Ukwunwangwu, Uturu, Abia State. Experimental research design was used and it was carried out at Uturu, Abia State, Nigeria. Three sampling locations were chosen, the bone, dung and slurry sections respectively and two control points labeled A and B respectively. The first set of samples were collected in the morning to ensure freshness and the second set of samples were collected after two weeks making it a total of eight samples used for this study. These samples were collected at different sections so as to know the variations in concentrations of the following important physico-chemical parameters: pH, Temperature, Moisture Content, Soil Organic Carbon, Cation Exchangeable Capacity and Soil Exchangeable Acidity. The temperature was taken in-situ using a mercury-in-glass thermometer. Results of analyses revealed that UK3A had the highest temperature of 35.00C in the first week and also 35.20C after two weeks, control A had the highest pH value of 8.2mg/l in the first week while UK2B had the highest pH of 8.5mg/l after two weeks. Control A had the higher moisture content value of 58.08% in the first week while UK3B had the highest value of 54.81% after two weeks. UK1A had the highest soil organic carbon 30.5 in the first week and also after two weeks. UK3A had the highest soil exchangeable capacity of 0.6 in the first week while UK3B had the highest value of 0.5 after two weeks. UK3A had the highest cation exchangeable capacity of 5.0 in the first week while UK2B had the highest value of 4.8 after two weeks. The correlation between the results was done using the Pearsons Correlation Moment. The experiment will help reduce the impact of abattoir waste on the environment by reducing the effect of global Climate Change and other environmental hazards. The study therefore recommended that strict environmental laws that can help curb the effects of abattoir wastes on the environment be enforced.

Variation in body size and weight status among Hindu and Muslim Indian males born in the 1890s through the 1950s

Hindus and Muslims represent the two largest religions in India, and also differ in nutritional status, health-related habits and standard of living associated with economic disparities. In this context, the present study considered estimated secular changes in body size, proportions, and weight status among Hindu and Muslim Indian men. The data are from anthropological surveys in the 1970s which included measurements of height, weight and sitting height of 43,950 males 18–84 years (birth years 1891–1957). Leg length was estimated; the BMI and sitting height/height ratio were calculated. Heights of men 35 + years were adjusted for estimated height loss with age. Weight status was also classified relative to WHO criteria for the BMI. Anthropometric characteristics of the two groups were compared with MANCOVA with age and geographic region as covariates. Linear regression of height on year of birth was also used to estimate secular change in each group. Heights, weights, and BMIs tended to be, on average, greater among Muslim than Hindu men at most ages, while distributions by weight status between groups were negligible. Sitting height was greater among Muslim men but estimated leg length did not differ between groups; the sitting height/height ratio thus suggested proportionally shorter legs among Muslim men. Results of the regression analyses indicated negligible differences in secular change between groups across the total span of birth years but indicated a decline in adjusted heights of men in both groups born between 1891 through 1930s and little secular change among those born in the 1930s through 1957. The variation in heights, weights and BMIs between Muslim and Hindu men at most ages suggested variation in socio-economic status and dietary habits between the groups, whereas the negligible estimated secular changes in height between groups likely reflected economic, social, and nutritional conditions during the interval of British rule and the transition to independence.

Ocular parameters associated with visual performance of enhanced monofocal intraocular lens

BackgroundAn enhanced monofocal intraocular lenses (IOLs) (Tecnis Eyhance ICB00 and Tecnis Eyhance Toric DIU) has been developed to enhance intermediate vision while avoiding the disadvantages of multifocal IOLs. Although many studies have demonstrated the improvement of intermediate visual acuity with enhanced monofocal IOLs, it is not known specifically for which patients these IOLs should be recommended or avoided. In this study, we aim to find out which ocular parameters affect vision performance and photic phenomenon of ICB00 or DIU at different distances.MethodsPatients who underwent cataract surgery with ICB00 or DIU, performed by a single surgeon, were included. Before surgery, the patients’ age, gender, axial length, anterior chamber depth, spherical aberration Z (4,0), vertical coma, horizontal coma, angle kappa (κ), angle alpha (α), and other ocular parameters were investigated. One month after surgery, uncorrected near visual acuity (UNVA at 40 cm), uncorrected intermediate visual acuity (UIVA at 66 cm), uncorrected distance logMAR visual acuity (UDVA), IOL decentration, and quality of vision (QoV) questionnaires were conducted.ResultsA total of 43 patients (58 eyes) were included. The results of the univariate linear regression analyses showed a negative correlation between spherical aberration and logMAR UNVA and UIVA (p = 0.003, β=-0.51 and p = 0.018, β=-0.23, respectively) and a positive correlation between angle α and logMAR UIVA (p = 0.036, β = 0.19). Deeper anterior chamber depth (ACD) was associated with poorer total QoV (p = 0.018, β = 14.43), particularly in glare, halo, blur, and fluctuation perception. A higher degree of IOL decentration tended to decrease UNVA and UIVA (Pearson correlation coefficient, r = 0.336 and r = 0.221, respectively); however, no significant effect was observed on UDVA (Pearson correlation coefficient, r = 0.042).ConclusionsIn enhanced monofocal IOLs, a higher level of spherical aberration is associated with better performance in UNVA and UIVA, whereas a larger angle α has a negative impact. A deeper ACD negatively affects the QoV.

Closed‐loop of Catalyzed Lactate Oxidization Synergistically Sensitizes Apoptosis and Ferroptosis for Cancer Therapy

AbstractLactate accumulated in Tumor is a key oncometabolite and associated with various oncogenic processes, including proliferation, invasion, angiogenesis, metastasis, immunosuppression and therapeutic resistance. Particularly, lactate contributes to the apoptosis and ferroptosis resistance in cancer cells. Consequently, blockade of lactate provides a promising opportunity for cancer therapy. However, due to abnormal tumor microenvironment (TME) and intracellular glutathione (GSH) mediated ferroptosis resistance, the current approaches for regulating lactate to sensitize cells to apoptosis and ferroptosis are still challenging. Herein, we developed a catalytic lactate oxidizing liposomes (Lip‐LM) incorporated with lactate oxidase (LOX)‐loaded MnO2 nanoparticles. O2 regenerated from H2O2 constitute closed‐loop of lactate oxidation catalyzed by LOX, enhancing the lactate‐consuming efficacy in TME. Besides, glutathione is consumed by MnO2 to amplify the ferroptosis susceptibility of cancer cells. The results showed that Lip‐LM achieved synergistical apoptosis and ferroptosis to enhance the anti‐tumor efficacy of amplified oxidative stress in cancer cells through the strategy of self‐sufficient O2 supplying and GSH consumption. The results of transcriptomics and proteomics analyses also support the synergistical anti‐tumor mechanisms of Lip‐LM. Hence, it is a promising catalytic nanoplatform combined lactate regulation and oxidative stress amplification and have great potential to further enhance therapeutic outcomes based on synergistical apoptosis and ferroptosis.

Validity of automated essay scores for elementary-age English language learners: Evidence of bias?

Given increased prevalence of automated writing evaluation (AWE) systems in classroom settings, more research is needed to explore the potential for bias in automated scores with respect to English language learners (ELLs). Thus, this research study investigated and compared the predictive validity of automated and human scoring methods for elementary-age English ELLs on a writing test designed for ELLs and a state writing test designed for the general population. This study focused on the MI Write AWE system and sampled 2829 students comprising ELLs and non-ELLs in Grades 3–5. Results of multilevel regression analyses and simple slopes estimation indicated that, for ELLs, the automated MI Write score had similar predictive validity to the human score for both writing tests. However, automated and human scores for ELLs were less closely related to the state writing test score than scores for non-ELL students. Findings suggest that MI Write’s automated scoring was not uniquely biased relative to human scoring but does reproduce the same biases evident with human scoring. Implications and directions for future research are discussed.

Enhancing pectin extraction from orange peel through citric acid-assisted optimization based on a dual response

Pectin is widely used in several products in the industry. Conventionally, strong and harmful acids are used for its extraction. This study optimized the extraction of orange peel's pectin using citric acid, considering yield and degree of esterification (DE) as response variables. Proximal analyses were performed, and the samples were subjected to a Box-Behnken design on three central points, considering as variables the temperature, time, and pH. The results of proximate analyses of the orange peels revealed 11.76 % moisture content, 87.26 % volatiles, 0.09 % ash, 50.45 % soluble carbohydrates, 70.60 % total carbohydrates, 0.89 % fixed carbon, 5.35 % lipids, and 36.75 mg GAE/g of phenolic compounds. The resulting second-order polynomial model described the relation of the input and output variables related to each other. The best performance to obtain a higher yield (18.18 %) of high methoxyl pectin (DE 50 %) was set at 100 °C/30 min/pH 2.48. Pectin showed antioxidant properties by ABTS and DPPH assays and similar thermal properties to the commercial polymer. Its equivalent weight was 1219.51 mol/g, and the methoxyl and anhydrouronic acid were 2.23 and 67.10 %, respectively. Hence, pectin extraction with citric acid results in a high-quality polymer and could be used as a gelling agent, stabilizer, or texturizer in food products.

A strain-hardening macro-element model for pile groups under vertical–horizontal-moment loading

AbstractPile foundations supporting wind turbines, silos, elevated water tanks or bridge piers are frequently subjected to multi-component loads, which may lead to significant rotations and settlements compromising the safe operation of the structure. The prediction of these displacements is of major concern and can be easily carried out using force-resultants plasticity models, also referred to as ‘macro-elements’, stemming from the idea of describing the foundation behaviour by a single upscaled constitutive relationship between generalized forces and displacements. When properly formulated, they can reproduce key aspects of the mechanical response of the foundation at low computational cost as compared to numerical analysis. To this end, a new macro-element for pile groups formulated in the classical framework of strain-hardening elasto-plasticity is presented and discussed. The required model parameters can be calibrated by closed-form equations and additional few data of numerical and/or experimental nature. The proposed mathematical framework is finally validated against the results of centrifuge tests and 3D finite element analyses.

Metagenomic analysis reveals the presence of prunus virus I in diseased Clematis vitalba: first record of this virus in Italy

Prunus virus I (PrVI) was detected for the first time in Clematis vitalba in Italy using high-throughput sequencing and the complete genome of this isolate, named Clv-1, was assembled and characterized. The results of the bioinformatic analyses were further validated with RT-PCR assays using PrVI-specific primers and Sanger dideoxy sequencing. The Clv-1 genome included three RNA segments of nucleotide lengths of 3468 (RNA1), 2892 (RNA2) and 2225 (RNA3), with five predicted open reading frames. Phylogenetic analyses showed close relationships with other PrVI isolates from different geographical origins, including European and non-European countries. This new pathogen record extends the information on the geographical distribution of PrVI, and possibly reflects the international movement of infected clematis germplasm due to global trade. Further surveys on the presence and distribution of PrVI in weeds and crops, such as the two PrVI hosts sweet cherry and peach, are required in the countries where PrVI has been detected.

Oxolane Ammonium Salts (Muscarine-Like)-Synthesis and Microbiological Activity.

Commercially available 2-deoxy-D-ribose was used to synthesize the appropriate oxolane derivative-(2R,3S)-2-(hydroxymethyl)oxolan-3-ol-by reduction and dehydration/cyclization in an acidic aqueous solution. Its monotosyl derivative, as a result of the quaternization reaction, allowed us to obtain eight new muscarine-type derivatives containing a quaternary nitrogen atom and a hydroxyl group linked to the oxolane ring. Their structure was fully confirmed by the results of NMR, MS and IR analyses. The crystal structure of the pyridinium derivative showed a high similarity of the conformation of the oxolane ring to previously published crystal structures of muscarine. Two reference strains of Gram-negative bacteria (Escherichia coli ATCC 25922 and Pseudomonas aeruginosa ATCC 27853), two reference strains of Gram-positive staphylococci (Staphylococcus aureus ATCC 25923 and Staphylococcus aureus ATCC 29213) and four reference strains of pathogenic yeasts of the genus Candida spp. (Candida albicans SC5314, Candida glabrata DSM 11226, Candida krusei DSM 6128 and Candida parapsilosis DSM 5784) were selected for the evaluation of the antimicrobial potential of the synthesized compounds. The derivative containing the longest (decyl) chain attached to the quaternary nitrogen atom turned out to be the most active.

Contribution of Social Bonds to the Development of Scientific Research Identity in Adolescent Participants of a Science Enrichment Program

An abundance of research on self-determination theory has shown that satisfaction of basic needs for autonomy, competence, and relatedness among adolescents promotes the experience of optimal career-related outcomes such as academic motivation and engagement. However, few studies have explored how satisfaction of these needs promotes identification with particular careers, and less attention has been paid to the role of relatedness satisfaction in these developmental processes compared to autonomy and competence. We addressed these issues in the current study by examining the relationship between relatedness and identification as a research scientist. Five latent classes of scientific research identity development were identified using growth mixture modeling: (a) strong positive growth, (b) moderate positive growth, (c) weak positive growth, (d) no growth, and (e) strong negative growth. Results of logistic regression analyses indicated that need for relatedness was a significant positive predictor of membership in the strong positive growth class relative to the no growth class. Implications for identity development as a research scientist and the social and motivational influences undergirding this process are discussed.

Tuning the Catalytic Selectivity Toward C2+ Oxygenate Products by Manipulating Cu Oxidation States in CO Electroreduction.

Enhancing the reaction selectivity for multicarbon products (C2+) is an important goal for the electrochemical CO(2) reduction (ECO(2)R) process. Cuprous compounds have demonstrated promising C2+ selectivity in the ECO(2)R process, but further investigation is necessary to thoroughly elucidate their catalytic behavior toward C2+ oxygenate production. In this study, copper nitride-based materials with varying reduction rates were employed as precatalysts. Consequently, a relationship between the selectivity toward C2+ oxygenates and the Cu oxidation state during the ECOR process is established. Results of theoretical and experimental analyses reveal that the Cu0/Cu+ interface plays a key role in enhancing *CO adsorption while lowering the formation energy of *CH2CO, thereby promoting acetate production. This work highlights the significance of the Cu0/Cu+ interface in the regulation of C2+ oxygenate production and paves the way for the development of highly selective catalysts in the future.

Animal-Assisted Psychotherapy: A Meta-Analytic Review

Abstract In this meta-analysis, we examine the efficacy of animal-assisted psychotherapy (AAP) on mental disorders. Twenty-eight studies quantitatively assessed the treatment effects of AAP. We used a random effects model to aggregate each study into an overall effect size. We found a large effect for pre- versus post-intervention comparisons and a moderate effect for the treatment versus control comparison for all disorders. Most of the moderator analyses were non-significant. We used the Grade measure (Grading of Recommendations, Assessment, Development and Evaluation) to assess the quality of the studies included in this paper. The results of the Grade analyses indicated a score of very low quality on the assessment. Therefore, only tentative conclusions about the efficacy of AAP can be drawn. The results suggest that AAP is a potentially efficacious treatment for mental disorders; however, significant limitations temper this conclusion.

Contributions of group identification and emotional synchrony in understanding collective gatherings: A meta-analysis of 13 studies

The present research aims to explore the relationship between group identification and emotional synchronization in a series of collective gatherings and evaluate their respective effects on key social-psychological variables. Thirteen studies were conducted in highly varied contexts, studying naturally happening phenomena, and focusing on a wide range of collective gatherings ( N = 2,260 participants). The results of factor analyses and a random-model meta-analysis strongly support the idea that group identification and emotional synchronization constitute two differentiated constructs that are systematically positively associated. At the aggregate level, results of multilevel models show that both group identification and emotional synchronization are significant predictors of key social-psychological variables. These findings suggest that an integrative approach is most needed to capture the experience of collective gatherings.

The impact mechanism of carbon emission reduction performance on financial performance based on carbon neutral targets: Evidence from Chinese energy enterprises

Purpose: Low-carbon and green technologies are crucial for achieving industrial structure upgrades and significant leaps forward in the development of energy enterprises. Therefore, this paper examines the correlation between carbon emission reduction and financial performance in energy firms.
 Design/Methodology/Approach: A two-way fixed-effects model is developed using data from 33 Chinese energy-listed companies between 2015 and 2020.
 Findings: The benchmark regression results show that improving a company's carbon emission reduction performance leads to better financial performance. Moreover, assuming corporate responsibility for reducing emissions can boost companies' reputations and foster better relationships with stakeholders. The trustworthiness of the standard regression outcome is validated through alternative independent variables, reducing time frames, and incorporating previously omitted factors. The results of heterogeneity analyses show that reducing carbon emissions has the same effect on financial performance across all regional characteristics and equity subgroups. Furthermore, the internal transmission mechanism analysis reveals that female leadership positively moderates the effect, while financing constraints negatively moderate the relationship between carbon emission reduction performance and financial performance.
 Conclusion: Under the national green development strategy of achieving carbon neutrality and carbon peaking, the carbon information disclosure system should be improved by the government; enterprises should implement innovative methods for low-carbon economic management and operation; and regulators should establish effective green regulations, incentives, and constraints. This paper offers a comprehensive guide for energy companies and their stakeholders to reduce carbon emissions, thereby achieving sustainability.

A user acceptance model for e-HRM system implemented in IT and Non-IT business organizations

BACKGROUND: Nowadays organizations have made their human resource management process more strategic and serve as a strategic tool for achieving competitive advantage for the organization with the development of electronic-Human Resource Management (e-HRM) Systems. To measure e-HRM system acceptance for performing various HR functions of an organization, especially the HR department, a perception model for acceptance of e-HRM systems in IT and Non-IT organizations has been developed in this research paper. OBJECTIVE: The objective of the study is to derive an acceptance model that can predict the acceptability and the factors affecting the acceptance of e-HRM systems in IT and Non-IT organizations. For this purpose, an electronic-survey-based questionnaire with a set of questions with categorical response options has been developed and the responses collected through this questionnaire are eligible to measure the acceptance level with effectiveness and usefulness of the e-HRM systems by IT and Non-IT business organizations. METHODS: Here, the questionnaire has 22 parameters. During data collection, 400 samples are obtained from 20 IT and 20 Non-IT (other services) organizations where ten employees from each organization participated in the survey. For the Data analysis for the acceptance model and also for testing of the hypothesis, several statistical-based data analysis techniques such as Data Reliability, Cross Tabulation, Normality test, Correlation ∖& Regression-based analysis, Factor Analysis, along with Pearson Chi-Square, Mann-Whitney U, Wilcoxon W for hypothetical testings are done. Apart from these criteria, using the data analysis techniques, a well-known technology acceptance model for the e-HRM system has also been employed to test with variables of the proposed questionnaire for the acceptance of e-HRM systems. RESULTS: All the statistical tests and testing of hypotheses are done in a sequential manner for comparison purposes of factors that affect e-HRM systems in IT and Non-IT organizations. The results are reported in detail with explanations and justifications. CONCLUSION: The results of the data analyses can be concluded with finding and discussing that the acceptability of e-HRM systems by the end users in IT firms is much higher than in other service organizations because of the significant difference in presence of external factors, perceived usefulness, perceived ease of use, user attitude, and behavior between the IT and Non-IT groups of organizations.

The relationship between passion and athlete identity in sport: the mediating and moderating role of dedication

BackgroundIn addition to the fact that the concept of passion in sports plays a significant role in the formation of the identity concept of athletes, the dedication of athletes to the sports branches they are interested in also has a significant impact on their passion for the sport they are interested in as well as their identity as an athlete. In this direction, the research aims to investigate the role of dedication as a mediator and moderator in the relationship between athlete identity and passion in sport.MethodsThe research was designed using the quantitative research technique of relational surveying. As data collection instruments for the research, the athlete identity scale, the passion in sport scale, and the sports commitment scale were utilized. 237 amateur and professional athletes, of which 142 were male and 95 were female (Mage = 22.7), participated voluntarily in the study by random sampling. The data were analyzed with the PROCESS and Jamovi programs in order to examine the direct and indirect effects.ResultsSignificant effects of sports passion on commitment and athlete identity were found. Since both dedication and athlete identity had a significant effect on passion for sports, it was determined that passion for sports continues to influence athlete identity through the medium of dedication. The moderator significance of medium, high, and low values of devotion was determined.Ethics approval number226394, date of registration: 03/11/2022.ConclusionOn the basis of the results of the statistical analyses, it was determined that the concept of dedication has a mediating and moderating effect on the relationship between sports passion and athlete identity.
