An Examination Of Followers’ Motivation To Serve As An Antecedent Of Servant-Leadership In Uk Organisations, Ijeoma G. Ukeni

International Journal of Servant-Leadership

Motivation to serve is conceptualised as an antecedent of servant-leadership but is mostly studied from the leaders’ perspective. Yet, as in any dyadic relationship, exploring the followers’ perspective is crucial, particularly as servant-leadership is an acclaimed follower-centric leadership theory. Hence, this quantitative study is a departure from the norm with a focus on the followers’ motivation to serve (MTS). Premised on the social learning theory, data was collected from 208 respondents in UK private and public organisations using existing and adapted questionnaire surveys that were statistically analysed. The results show a correlation between motivation to serve and servant-leadership but suggest …

Beyond Average Effects In Education Research Syntheses: Explaining Heterogeneity Of Concept Mapping Research In Science Education Through Meta-Regression Modeling, Aaron Wenger

Dissertations

Contemporary education research seeks causal inferences in order to guide policy and practice. Often well-controlled quasi-experimental and experimental designs are used as they are very useful for supporting and contextualizing causal inferences. Nevertheless, individual studies, even high-quality, resource-intensive randomized controlled trials, are not able to establish generalized claims. Because primary studies vary over dozens of variables (e.g., grade, subject, duration) simply conducting additional primary studies cannot change this. Furthermore, the informal assessments of primary studies common in literature reviews are unable to resolve certain challenges (e.g., publication bias) that are described in the emerging field of meta-research. These challenges require …

Persuasion Vs. Coercion Or Persuasion And Coercion, Jiying Song

International Journal of Servant-Leadership
