Poor project requirements definition and management (RDM) is one of the major causes of project failure. However, many organizations do not adequately manage a project's requirements leading to a poor design basis. Thus, quality of requirements is critical to the success of any construction project. The primary purpose of this research was to investigate the mediating effect of requirements quality on the relationship between RDM practice and project performance. The second objective was to determine whether the impact of RDM practice on project performance was moderated by project characteristics. A three-phase approach was employed to investigate construction projects in the Taiwanese building industry. The testing supports a role for requirements quality as a partial mediator in the relationship between RDM practice and project performance. The findings also indicate that project characteristics have a moderating effect on the relationship between requirements quality and overall project performance. Santrauka Prastai apibrėžti ir valdomi projekto reikalavimai – viena iš pagrindinių projekto nesėkmės priežasčių. Tačiau daug organizacijų neskiria pakankamai dėmesio projekto reikalavimų valdymui, todėl sukuriamas prastas projektavimo pagrindas. Taigi kokybės reikalavimai yra esminis sėkmės garantas bet kuriame statybų projekte. Pagrindinis šio tyrimo tikslas – išnagrinėti, kaip reikalavimų kokybė veikia jų apibrėžimo ir valdymo ryšį su projekto efektyvumu. Antrasis tikslas – nustatyti, ar projekto savybės mažina reikalavimų apibrėžimo ir valdymo poveikį projekto efektyvumui. Pritaikius trijų etapų metodą, išnagrinėti statybų projektai Taivano statybų sektoriuje. Bandymai patvirtino, kad reikalavimų kokybė iš dalies keičia jų apibrėžimo ir valdymo ryšį su projekto efektyvumu. Išvados taip pat rodo, kad projekto savybės riboja reikalavimų kokybės bendram projekto efektyvumui poveikį.

Change orders are ubiquitous in construction projects, and effective and efficient control of changes is critical to project success. There have been many empirical suggestions as to how to manage changes for best project outcomes, but this research is specifically aimed at exploring the relationship between project characteristics and the implementation of project change management best practices (PCMBP). Construction project data for this research are derived from the Construction Industry Institute (CII) benchmarking and metrics (BM&M) database. Binary logistic regressions and factorial analysis of variance (ANOVA) are performed to find out the differences among diverse types of projects in terms of the extents to which the PCMBP elements have been implemented. The findings can assist construction industry practitioners with using PCMBP more purposefully in accordance with specific project characteristics so that they will be better able to develop and administer their project execution plans.

The concept of Design and Build quickly becomes the preferred form of project completion. With this concept, it is possible for a project to be completed more quickly, with quality and costs according to plan. However, based on the results of research on construction projects in Jakarta, there are many that do not meet expectations.This study aims to determine the relationship of project owner factors, planner-builder factors, and project characteristics on airport design projects. Based on PLS SEM analysis of 65 respondents, it was found that the factor of the project owner has a positive but not significant effect on the performance of the Airport project, the builder planner has a negative but not significant effect on the performance of the Airport project, while the project characteristics factor has a positive and significant effect on project performance Airport.The results of this study provide confirmation and direction in the work of design projects in the future, especially for design projects at the airport.

Little is known about the relationship between social comparison orientation and mental health, especially in the psychological capital context. We proposed a theoretical model to examine the impact of ability- and opinion-based social comparison orientation on mental health using data from 304 undergraduates. We also examined the mediating effect of the four psychological capital components of hope, self-efficacy, resilience, and optimism in the relationship between social comparison orientation and mental health. Results show that an ability (vs. opinion) social comparison orientation was negatively (vs. positively) related to the psychological capital components. Further, the resilience and optimism components of psychological capital fully mediated the social comparison orientation–mental health relationship. Our findings indicate that psychological capital should be considered in the promotion of mental health, and that the two social comparison orientation types have opposite effects on psychological capital.

Abstract Background Breastfeeding is associated with healthier weight and nutrient status in early life. However, the impact of breastfeeding on carotenoid status beyond infancy, and the influence of adiposity, is unknown. Objective The aim of the study was to retrospectively investigate the relationship between breastfeeding and carotenoid status, and the mediating effect of weight status and adiposity on this relationship among school-aged children. Methods This was a secondary analysis of baseline data collected from a randomized-controlled clinical trial. (ClinicalTrials.gov Identifier: NCT03521349). 7–12-year-old (n = 81) children were recruited from East-Central Illinois. Dual-energy x-ray absorptiometry (DXA) was used to assess visceral adipose tissue (VAT) and whole-body adiposity (%Fat). Weight was obtained to calculated body mass index percentile (BMI %ile). Skin carotenoids were assessed via reflection spectroscopy. Macular carotenoids were assessed as macular pigment optical density (MPOD). Dietary, birth, and breastfeeding information was self-reported by parents. Results Skin carotenoids were inversely related to %Fat (P < 0.01), VAT (P < 0.01) and BMI %ile (P < 0.01). VAT and BMI %ile significantly mediated this relationship between exclusive breastfeeding duration and skin carotenoids, following adjustment for dietary carotenoids, energy intake, and mother education. Conclusions Weight status and adipose tissue distribution mediate the positive correlation between exclusive breastfeeding duration and skin carotenoids among children aged 7–12 years. The results indicate the need to support breastfeeding and healthy physical growth in childhood for optimal carotenoid status.

This study aimed to verify the impact of servant leadership on innovative behaviour in non-governmental organisations (NGOs). It particularly investigated the role of a mediator for self-efficacy in the relationship between servant leadership and innovative behaviour. This study defined the organisational psychology-behaviour mechanism in non-profit organisations by verifying the moderated mediating effect of vocational calling in the relationship between servant leadership, self-efficacy, and innovative behaviour. The 174 pilot samples used in this study comprised community service participants in NGOs. The analysis verified the hypothesis set through causal correlations among four variables using regression analysis and the PROCESS macro developed by Hayes. Vocational calling played a moderating role in the relationship between servant leadership and self-efficacy, and vocational calling had a conditional effect on the impact of servant leadership on innovative behaviour through self-efficacy. Meanwhile, self-efficacy fully mediated servant leadership and innovative behaviour. Based on the verification of the mechanism of organisational psychology-action, this study sought ways to develop the organisation of NGOs and improve the working environment.

With the advent of the Internet and other digital technologies, contemporary businesses from all sectors are using social media for communication with consumers to engage them meaningfully with a brand. However, the use of social media for corporate social responsibility (CSR) communication is relatively new to the existing literature. Likewise, the impact of CSR communication through social media (CSR-S) on consumer emotions and behavior is, to date, underexplored. To address this, the present research aims to test the relationship of CSR-S on brand admiration and consumer purchase intention. The study proposes a direct relationship between CSR-S and purchase intention with a mediating effect of brand admiration. The data were collected from the banking consumers of Pakistan through a self-administered questionnaire. The authors distributed 800 questionnaires and received 463 questionnaires useful for data analysis, so the present research study response rate was around 59%. The data were analyzed using the structural equation modeling (SEM) technique in AMOS. The results revealed that CSR-S is positively related to purchase intention (β = 0.233). The results further showed that brand admiration partially mediates this relationship (β = 0.079). The survey respondents confirmed that their bank’s CSR communication helps enhance their purchase likelihood and their feelings of admiration for their bank. These findings will help policymakers at banking institutions better understand the importance of CSR communication on different social media platforms to achieve consumer-related outcomes.

Purpose – Leader-member exchange (LMX) has been proposed as a core mechanism which accounts for the impact of various antecedents on employee outcomes. As such, the purpose of this paper is to examine the mediating effect of LMX regarding the relationship between leader positive humor and employees’ perceptions of organizational cynicism. Design/methodology/approach – Data were collected from 114 public employees. In order to examine the authors’ hypotheses hierarchical regression analysis was conducted. Findings – As hypothesized, results demonstrated that LMX mediates the relationship between leader positive humor and organizational cynicism. Research limitations/implications – Data were drawn from public employees and, therefore, this may constrain the generalizability of the results. Also, the cross-sectional analysis of the data cannot directly assess causality. Originality/value – This is the first empirical study to examine the mediating effect of LMX in the relationship between leader humor and employees’ perceptions of organizational cynicism.

Organizational scholars concurred that positive workplace relationships with others can helps employee to gain from these relationships but, they lack insights into how or why this occurs. Moreover, the relationship dynamics focus on what the relationships provide without considering the how these relationships initiated, builds and maintains. To line of this, the current study aims to find the impact of mentoring functions (career, psychosocial, role modeling) and employee performance (career success, organization citizenship behavior, and job performance) via mediating effect of relational self-efficacy. For this purpose, the data were gathered from 310 branch banking employees of Pakistani conventional banks. PLS-SEM was used for data analysis. The results indicate that there is direct relationship between mentoring functions and employee’s performance. Moreover, the finding also shows that employee relational self-efficacy mediates the relationship between mentoring functions and employee performance. Theoretical and practical implications are discussed along with suggestions for future research.

This study examined the impact of E-CRM on customer loyalty with the mediating effect of customer satisfaction in the banking industry. Customer satisfaction is important for loyalty because when the customers are satisfied with the services offered by their service providers, the relationship gets stronger which further leads to positive word-of-mouth. The data was collected using purposive sampling from 836 banks’ customers who were using E-CRM services and the data was analyzed using structural equation model (SEM) through AMOS. The results revealed that E-CRM and customer satisfaction had a significant positive impact on customer loyalty and also customer satisfaction partially mediated the relationship between E-CRM and customer loyalty. This study would offer useful acumen to both academicians and marketers and would help the bank managers to improve the quality of the services provided to their customers.
