This paper aims to systematically analyze the reasons for the differences in the relationship between transformational leadership (TL) and project success and apply meta-analysis to summarize which dimensions of TL are the main driving forces for project success. Adopting the meta-analysis approach, we investigated 31 independent studies (N = 6475) and studied the theoretical moderators of this relationship from the perspectives of mediating variables, cultural background, and document type to test whether the moderating effects can explain the inconsistent research results. The results reveal that TL positively affects project success and leadership charm is the primary driver of TL. Also, the existence of a mediating mechanism has a more significant impact on the success of the leading project. Meanwhile, compared with project construction under the Western cultural background, countries with Eastern culture are more inclined to use a people-oriented philosophy for project management to promote project success. This research provides an empirical perspective to help project leaders select management talents, regulate leaders’ words and deeds, and cultivate technical and soft leadership skills. Besides, this paper proposes a unique and nuanced view of the relationship between TL and project success, enhancing people’s understanding of the TL’s role in influencing project success.

Objective To explore the impact of appendectomy history on emergence of Parkinson’s disease (PD). Background Although there are several studies to investigate the relationship between appendectomy history and emergence of PD, the results are still controversial. Methods We performed a comprehensive electronic search of the literature (the Cochrane Library, PubMed, and the Web of Science) up to April 2020 to identify studies that had employed databases allowing comparison of emergence of PD between patients with and those without appendectomy history. To integrate the impact of appendectomy history on emergence of PD, a meta-analysis was performed using random-effects models to calculate the risk ratio (RR) and 95% confidence interval (CI) for the selected studies, and heterogeneity was analyzed using I2 statistics. Results Four studies involving a total of 6 080 710 patients were included in this meta-analysis. Among 1 470 613 patients with appendectomy history, 1845 (.13%) had emergences of PD during the observation period, whereas among 4 610 097 patients without appendectomy history, 6743 (.15%) had emergences of PD during the observation period. These results revealed that patients with appendectomy history and without appendectomy had almost the same emergence of PD (RR, 1.02; 95% CI, .87-1.20; P = .83; I2 = 87%). Conclusion This meta-analysis has demonstrated that there was no significant difference in emergence of PD between patients with and those without appendectomy history.

Purpose – The purpose of this paper is to qualitatively validate the constructs of a theoretically derived research model while gaining insights to steer the direction of a greater study on methodologies, their elements, and their impact on project success. In doing so, to investigate whether different project environments, notably project governance, impacts the relationship between methodologies and project success. Design/methodology/approach – A deductive approach was applied to validate a theoretically derived research model. In total, 19 interviews across 11 industrial sectors and four countries were used to collect data. Pattern-matching techniques were utilized in the analysis to deductively validate the research model. Findings – There is a positive relationship between project methodology elements and the characteristics of project success; however, environmental factors, notably project governance, influence the use and effectiveness of a project methodology and its elements with a resulting impact on the characteristics of project success. Research limitations/implications – Project governance plays a major role in the moderating effect of a project methodology’s effectiveness. Contingency theory is applicable to a project’s methodology’s selection and its customization according to the project environment. Practical implications – Understand the impact of project methodologies and their elements on the characteristics of project success while being moderated by the project environment, for example, the risk of suboptimal project performance due to the effectiveness of methodology elements being negatively impacted by the project environment. Originality/value – The impact of a project methodology (collection of heterogeneous-related elements) on the characteristics of project success is identified while being moderated by the project environment, notably project governance.

Purpose The purpose of this study is to determine the effect of conscientiousness and extraversion personality traits on project success. The relationship is mediated by affective professional commitment, whilst the relationship between personality traits and project success is moderated by organizational project management maturity. Design/methodology/approach The deductive approach is used to achieve the objectives of this study. Data were collected through a purposive sampling technique from 250 respondents with the help of questionnaires from information technology sectors. The structural equation modelling (SEM) in partial least squares-SEM and SPSS is used to analyse the data and to examine the hypothesis. Findings The outcomes demonstrate the partial mediating impact of affective professional commitment between the relationship of conscientiousness and extraversion personalities with project success. Additionally, it proves the moderating effects of project management maturity between the relationship of conscientiousness and extraversion personalities with project success. Practical implications This study reflects that employee personality appears to be a reliable indicator of how an employee is faithful to his profession. This faithfulness or duty decides the employee’s execution in terms of offering a successful project. Thus, achieving employee commitment needs to be done by completing the project successfully by the organizations in the presence of project management maturity systems. Originality/value It is the first study of its kind to provide experimental proof of the impact of a manager’s personality traits on project success in the presence of affective professional commitment (mediator) and organizational project management maturity (moderator).

Abstract This non-experimental correlational study extends previous research investigating the relationship between project management methodology and reported project success, as well as the moderating variables of industry and project manager experience. The sample included North American project managers with five years’ experience, 25 years of age or older, and experience with multiple project management methodologies. The survey instrument consisted of 58 questions, utilizing a 5-point Likert scale to record responses. The survey contained three sections, including demographic information, questions related to a successful project, and questions related to a less-than successful (failed / challenged) project. 367 usable responses were received. The examination of the constructs included Pearson’s correlation coefficient as well as linear regression to determine the impact of moderating variables. Results indicated that project management methodology has a weak correlation with reported project success, and this correlation is not moderated by industry nor project manager experience. The results did not align with previously conducted studies, illustrating a need to continue the study of methods impacting success including investigating additional moderating variables.

Purpose – There are few studies that have studied the relationship between Transformational leadership (TL) and organisation commitment (OC), but there are very few studies on the service sector especially in the Indian context. This study aims to fill the gap in literature by empirically examining the impact of four dimensions of TL using Multifactor Leadership Questionnaire (MLQ) on the Affective Commitment (AC) of the employees, within the context of the service sector in Bengaluru. Design/methodology/approach – A total of two hypotheses were proposed for testing transformational leadership using Multifactor Leadership Questionnaire (MLQ) questionnaire, (Bass and Avolio, 1997) and five items of affective organization commitment developed by Allen and Meyer (1996) was used for affective commitment. The questionnaire was administered to 210 employees working in various industries in the service sector in Bengaluru to measure the impact of TL on the AC of the respondents. Findings – The analysis of the data collected shows that TL has a positive impact on the affective commitment of the employees. In particular, the results of an empirical investigation revealed that individualized influence and individual consideration by the transformational leader had a significant impact on the affective commitment level of the employees. The employees in the hospitality industry had a difference in opinion compared to IT, Banking & education sector employees on the intellectual stimulation by the leader and their affective commitment towards the organization. Originality/value – This paper contributes to the existing literature of leadership and OC by providing practical evidence leading to the improvement of information and the understanding of the relationship between TL and AC.

Estimating of cost for building construction projects with minimum error at the conceptual stage of project development is quite  essential for planning. This study seeks to evaluate factors responsible for cost escalation of building construction projects.  Questionnaires were administered to examine and assess these factors. Subsequently, the mean score value of each factor was determined. In addition, Correlation and Linear regression analyses were used to establish the relationship between these factors. Factors responsible for cost escalation in projects were examined as well as the impact of those factors, and occurrence of those factors on project cost. The result of the analysis showed that, the most agreed factors responsible for project cost escalation were; inadequate supervision, irregular payment, and design error, having high mean values of 4.25, 4.20, and 4.15, respectively. Also, correlation analysis result established that the factors responsible for cost escalation and the impact of cost escalation had significant R and R2 of 0.81 and 0.70 respectively. Addressing these factors would go a long way in reducing the escalation of building project cost. Never the less, an effective cost management strategy is absolutely necessary to safeguard and sustain the construction  industry.

Persuasion knowledge development leads to better coping with marketplace persuasion, better consumer decision-making, and adds to consumer well-being. While significant knowledge exists on the impact that individual factors (e.g., age) and cues (e.g., sponsorship disclosure messages) have on consumers’ persuasion knowledge development, little is known about the influence of marketer actions, such as advertising spending. This is surprising, as marketer activities provide a major source of information for consumers’ persuasion knowledge learning and practice and can theoretically either support or hinder persuasion knowledge development. We develop several explanations for various types of relationships between advertising spending and persuasion knowledge and test these relationships by means of a meta-analysis of the persuasion knowledge literature based on 140 papers with 162 distinctive datasets that address persuasion knowledge measurements. We find that increasing advertising spending also increases consumers’ persuasion knowledge. The relationship follows an inverted-U curve, and, at a certain level of advertising spending, persuasion knowledge begins to decrease. The findings have theoretical and societal implications and, depending on the level of advertising investment, policy implications with the ultimate aim of ensuring consumer well-being and protecting consumer groups with low levels of persuasion knowledge.
