Does weight mediate the effect of smoking on coronary heart disease? Parametric mediational g-formula analysis

Background In settings in which there are time-varying confounders affected by previous exposure and a time-varying mediator, natural direct and indirect effects cannot generally be estimated unbiasedly. In the present study, we estimate interventional direct effect and interventional indirect effect of cigarette smoking as a time-varying exposure on coronary heart disease while considering body weight as a time-varying mediator. Methods To address this problem, the parametric mediational g-formula was proposed to estimate interventional direct effect and interventional indirect effect. We used data from the Multi-Ethnic Study of Atherosclerosis to estimate effect of cigarette smoking on coronary heart disease, considering body weight as time-varying mediator. Results Over a 11-years period, smoking 20 cigarettes per day compared to no smoking directly (not through weight) increased risk of coronary heart disease by an absolute difference of 1.91% (95% CI: 0.49%, 4.14%), and indirectly decreased coronary heart disease risk by -0.02% (95% CI: -0.05%, 0.04%) via change in weight. The total effect was estimated as an absolute 1.89% increase (95% CI: 0.49%, 4.13%). Conclusion The overall absolute impact of smoking to incident coronary heart disease is modest, and we did not discern any important contribution to this effect relayed through changes to bodyweight. In fact, changes in weight because of smoking have no meaningful mediating effect on CHD risk.

The Mediating Effect of Dispositional Gratitude on the Relationship between Religious Struggles and Self-Esteem: Preliminary Results

In comforting or distressing circumstances, individuals tend to have various perceptions of themselves. It seems that religious comfort and religious distress correlate differently with people’s self-esteem. Since the relationship between religiosity and self-esteem is not only direct but can be mediated by other factors that are recognized as buffers against adverse situations, our main goal was to verify whether dispositional gratitude may have an indirect effect on the association between both variables. The research involved data from 254 participants aged 18 to 25 (M = 21.24; SD = 2.09) and included 192 women (76%) and 62 men (24%). To measure the title variables, we used: the Religious Comfort and Strain Scale (RCSS), the Rosenberg Self-Esteem Scale (RSES), and the Gratitude Questionnaire (GQ-6). The results showed that people who consider religion as a source of comfort express positive attitudes toward the self and recognize others’ kindness, as well. In contrast, people who consider religiosity as a cause of fear, stress, and internal strain tend to display a lower subjective sense of personal worth and lower appreciation of the positivity around them. Moreover, gratitude had a mediatory effect on the relationships between religious comfort/negative emotions toward God and self-esteem.

Understanding Girls' Motivation to Participate in Sport: The Effects of Social Identity and Physical Self-Concept

Introduction: Girls are often less motivated to participate in community sport compared to boys. Having a strong social identity with a sports team is positively associated with motivation to continue participation in sport, yet the mechanisms explaining this association are not well-known. In the current study, physical self-concept is tested as a mediator of the association between social identity and motivation.Method: Girl badminton athletes were recruited to examine how the team environment shapes physical self-concept, and whether this association relates to motivation to participate in sport. Ninety-two girls completed a self-report survey to measure social identity, physical self-perceptions, and motivation. Two mediation models were conducted to examine whether physical self-concept mediated the relationship between social identity and autonomous motivation and controlled motivation.Results: Physical self-concept partially mediated the relationship between social identity and autonomous motivation. The bootstrapped unstandardized indirect effect was, b = 0.05, 95% CI = 0.002 to.14. Physical self-concept fully mediated the relationship between social identity and controlled motivation. The bootstrapped unstandardized indirect effect was, b = −0.13, 95% CI = −0.30 to −0.01, p = 0.04.Discussion: These results highlight the importance of the group context in relation to individual physical self-concept and motivation. Overall, targeting aspects of the team environment in community-level sport may be an important strategy to improve girls' physical self-concept, and autonomous motivation to continue sport participation.

Determination of Company's Value: A Study with Investment Opportunity as a Moderator Variable

This research focuses on the state of a company's valuation, which is always changing. The utilized variables to estimate firm value include free cash flow and interest rates, both of which have a positive relationship with company's value. The second purpose is to investigate the current situation of investment opportunities in industrial companies that are similarly highly volatile. The availability of free cash flow indicates the interest rate has a positive relationship with the investment opportunity set. An explanatory research design is used in this study, which aims to examine the correlation between variables. The manufacturing companies that were listed on the Indonesia Stock Exchange between 2013 and 2018 are the focus of this study. Thus, data were collected from 612 units using a purposive sampling technique. The findings reveal that whereas free cash flow has a strong positive indirect effect on company value via mediating the investment opportunity set, interest rates have a negative and minor indirect effect on firm value via mediating the investment opportunity set.

Peran Citra Destinasi Pada Hubungan E-Wom Dengan Minat Kunjungan Wisatawan Di Pantai Losari, Kota Makassar

This study sees and analyzes the direct effect of e-WOM on visit intention and destination image, the direct effect of destination image on visit intention, and the indirect effect of e-WOM on visit intention through destination image. The methods of this study used a quantitative approach. I collected data through online questionnaires with a total sample of 200 respondents. The sampling technique used is purposive accidental sampling. Data analysis used the SEM-PLS method. The results showed that e-WOM has no direct effect and an insignificant positive relationship on visit intention, e-WOM has a positive and significant direct effect on destination image, destination image has a positive and significant direct effect on visit intention, and e-WOM has a positive and significant indirect effect on visit intention through destination image or destination image became a mediator between e-WOM and visit intention.

Authenticity or Self-Enhancement? Effects of Self-Presentation and Authentic Leadership on Trust and Performance

We theorized and tested an integrated model that examines the simultaneous effects of authentic self-expression and self-enhancement (including authentic and exaggerated self enhancement) on employee outcomes. Using a multisource, two-wave survey design and a sample of 143 working groups from 566 employees, we tested the indirect effects of self-presentation on job performance through (a) trust from coworkers and (b) felt trust from coworkers. We found that through trust from coworkers, authentic self-expression had a positive indirect effect on job performance, whereas authentic and exaggerated self-enhancement had negative indirect effects. Via felt trust from coworkers, authentic self-enhancement had a positive indirect effect on job performance, whereas exaggerated self-enhancement had a negative indirect effect. In addition, we identified a boundary condition of these relationships. The positive relationship between authentic self-expression and trust from coworkers and the negative relationship between exaggerated self-enhancement and trust from coworkers were stronger when working for highly authentic leaders. Contrary to expectations, the relationship between authentic self-enhancement and trust from coworkers was negative and significant when working for less authentic leaders.

FLOW EXPERIENCE AND CONSUMERS’ WILLINGNESS TO PAY IN ONLINE MASS CUSTOMIZATION PROCESSES

This research aims to identify the effects of perceived product value and flow experience during product design on willingness to pay (WTP) and purchase probability in online mass customization. The participants were asked to design shoes to their taste in a custom shoe website. After the design experience, the participants were asked to complete the questionnaire. The analyses suggest that flow experience has a direct effect on consumers’ WTP and an indirect effect on purchase probability through the mediating role of perceived value of mass customized products. Furthermore, perceived value of a mass customized product has a significant effect on purchase probability and no effect on WTP found in the analyses.

Peran Retrun On Assets (ROA) Sebagai Variabel Mediasi Pada Pengaruh Non Performing Loan (NPL) Dan BI Rate Terhadap Harga Saham Bank BUMN Periode 2011 – 2020

The purpose of this study is to provide empirical evidence regarding the direct effect of Non Performing Leon (NPL) and BI Rate on Return On Assets (ROA) and stock prices, indirect effect of Non Performing Leon (NPL) and BI Rate on stock prices through Return On Assets (ROA) as a mediating variable in state-owned banks for the period 2011 – 2020. This type of research is quantitative research. The data analysis technique used is multiple linear regression and mediation test using Eviews 12 program and Sobel Test Online. The results of this study show that simultaneously Non Performing Loans (NPL), BI Rate and Return On Assets (ROA) have a significant effect on stock prices. Partially 1). Non-performing loans (NPL) have a negative and significant impact on Return On Assets (ROA). 2) BI Rate has a positive but not significant impact on Return On Assets (ROA). 3). NPL (Non Performing Loan) has a negative and significant impact on stock prices. 4). BI Rate has a negatif and significant impact on stock prices. 5) Return on Assets (ROA) has a positive and significant impact on stock prices. Return on Assets (ROA) as a mediating variable is able to mediate the effect of non-performing loans (NPL) on stock prices, however, Return On Assets (ROA) does not mediate the effect of the BI Rate on stock prices.

COVID-19 fear and performance of workers: A moderated mediation role of organizational support and mental wellbeing

The paper aimed to examine the influence of employees’ COVID-19 fear on their performance through intervening mechanisms such as mental wellbeing and organizational support. A total of 446 workers from the bank completed a self-report survey. Findings from regression analysis conducted with SPSS PROCESS MACRO (Model 7) revealed that employees’ COVID-19 fear did not have any direct negative influence on their performance but instead had an indirect effect on their performance via mental wellbeing (anxiety and depression). The findings also revealed that organizational support was instrumental in buffering the adverse impact of employees’ COVID-19 fear via mental wellbeing (anxiety and depression). Therefore, organizations should increase employee-supportive measures throughout this era of the COVID-19 to help reduce the adverse impact of employees’ COVID-19 fear.
