The study follows a non-experimental, cross-sectional design using data collected from a survey. Results of linear regression analyses reveal role conflict and …

Employees Support As A Determinant Of Merger Success: Exploring The Organizational Context And Its Interventions During Post-Merger Integration, Abdulla Humaid Saif Aljarwan Alshamsi

Dissertations

Mergers is an extreme form of organizational change, which usually has an adverse impact on the merging organizations employees’ wellbeing. In literature it was argued that organizational integration after merger, which is referred to as Post-Merger Integration (PMI) is usually resisted by employees, which is considered as a major contributor to the high failure rates of mergers. It was further argued that employees’ resistance toward integration is attributed to stress, uncertainty, ambiguity and lack of clarity on the changes that merger and integration initiate. Therefore, PMI activities were assumed to psychologically traumatize employees and jeopardize their sense of belonging, attachment, …

An Examination Of Optimal Level Of Ceo Narcissism: Why, How, And When Narcissism Impacts Firm Performance, Scott Boswell

Dissertations

Chief Executive Officers (CEOs) may have narcissistic tendencies that impact the firm and its performance. We explore the definition of narcissism, how it is measured, and when it might be optimal or harmful to the firm’s performance. Leaders exhibiting higher scores on one or more Dark Triad traits often are viewed negatively both inside and outside the firm. Should such negative perceptions disqualify a leader who displays a measure of a Dark Triad trait? This research answers the primary question, is there an optimal level of CEO narcissistic traits and if so, are there moderating factors that impact the level? …

Institutional Logics And The Double Bottom Line: A Study Of Chikum Microfinance Bank Limited, Daniel Anyanwu

Dissertations

Microfinance institutions (MFIs) serve a social mission, while also having to focus on financial sustainability. Microfinance emerged as an alternative to traditional aid to the poor and aims to help alleviate poverty through providing them with financial services. MFIs can be self-sustainable and even profitable through income generating activities. This twin goal of commercial viability and social mission has generated much scholarly interest in the competition between two seemingly incompatible logics of action. Assumptions about the incompatibility of profit and mission motives have dominated the literature and led to a neglect of how some MFIs may be successful in integrating …

Servant Leadership Behaviors That Positively Influence On-Time Delivery Of Committed Work By Agile Teams In A Scaled Agile Framework, Rob Barclay

Dissertations

This research found strong evidence that leaders who use Servant Leadership Behaviors (SLBs) positively influence on-time delivery of committed work by scrum teams in a Scaled Agile Framework (SAFe). In organizations using a Scaled Agile Framework to manage large programs, Agile teams plan work called “stories” within an iteration, which can range from one to four weeks. The stories are ultimately intended to deliver functionality to the end-user and have enough information within them for business and technical people to understand the intent, develop, test, and demonstrate a vertical slice of system functionality.

Our research used Servant Leadership theory to …

The Masks We Wear In The Workplace Masquerade: An Examination Of Antecedents Of Facades Of Conformity And The Impact Of Abusive Supervision, Kevin Sansberry Ii

Dissertations

Years of research conducted into abusive supervision (Tepper, 2000) have provided a greater understanding of how abusive supervision impacts workers including various negative outcomes as well as employee coping mechanisms. One of the possible ways that an employee may respond to abusive supervision is feigning their agreement with organizational values. The literature is somewhat deficient, however, in examining the manifestation of these facades of conformity (Hewlin, 2003). In this study, the relationship between abusive supervision and facades of conformity was examined, as well as several moderators of this relationship. The results indicated that abusive supervision was positively and significantly related …
