A Meta-Analysis Of Fmri Studies On Emotion Processing In Major Depressive Disorder, Madison Morocco
A Meta-Analysis Of Fmri Studies On Emotion Processing In Major Depressive Disorder, Madison Morocco
Master's Theses
The processing of an emotional stimulus involves a multi-step process that includes appraising and identifying a stimulus as well as producing an affective state in response. Many individuals with depressive disorders such as major depressive disorder (MDD) experience impairments related to emotion processing, likely caused by changes in the structure and function of brain regions important for emotion processing. However, the precise neural differences underlying emotion processing impairments in MDD remain unclear given conflicting findings in the neuroimaging literature. This lack of clarity has hindered the development of novel neurostimulation treatments for MDD, which require targeting of specific brain areas. …
The Impact Of Compensation On Engagement And Organizational Tenure: The Moderating Role Of Perceived Organizational Support, Alexis Johnson
The Impact Of Compensation On Engagement And Organizational Tenure: The Moderating Role Of Perceived Organizational Support, Alexis Johnson
Master's Theses
Compensation is a crucial tool utilized by companies to help attract, retain, and motivate employees. However, previous research has overlooked the ways in which compensation might add value to important employee outcomes such as engagement and organizational tenure. Therefore, this present study aimed to close this gap by examining the relationship between pay level and engagement, as well as pay level and organizational tenure. It was hypothesized that higher pay levels would increase the engagement dimensions of dedication, vigor, and absorption in an employee, and that higher pay levels would increase organizational tenure in an individual. It also sought to …
Influence Of Night Work On Performance During Lunar Telerobotic Operations, Zachary Luke Glaros
Influence Of Night Work On Performance During Lunar Telerobotic Operations, Zachary Luke Glaros
Master's Theses
Real-time, reactive telerobotic mission control operations require personnel to actively operate remotely controlled vehicles or robots in real time. Due to the physical separation of the vehicle from the operator, such operations present additional factors that can influence fatigue (degraded mental performance) and workload (mental and physical cost of task requirements), making it difficult to assess how long an individual can conduct operations safely. The upcoming Volatiles Investigating Polar Exploration Rover will involve remotely controlling a lunar vehicle from an Earth-based mission control station. In order to determine how long personnel could successfully maintain alertness and performance while operating a …
Inclusive Leadership, Psychological Empowerment, And Affective Organizational Commitment: A Mediated Model, Mariah Lyn Van Buskirk
Inclusive Leadership, Psychological Empowerment, And Affective Organizational Commitment: A Mediated Model, Mariah Lyn Van Buskirk
Master's Theses
Inclusive leadership has become an important contextual factor to study in organizations given its impact on positive workplace outcomes. However, little is known about the ability of inclusive leadership to affect a wider range of outcomes and the various mediating mechanisms between inclusive leadership and outcomes. Therefore, the present study explored the mediating role of psychological empowerment on the relationship between inclusive leadership and affective organizational commitment. It was hypothesized that inclusive leadership would be positively related to affective organizational commitment both directly and indirectly through psychological empowerment. Results of an online survey from 189 employed individuals showed that inclusive …
The Relationship Between Company, Manager, Group, And Individual-Level Variables And Affective Commitment, Varavit Chinnapong
The Relationship Between Company, Manager, Group, And Individual-Level Variables And Affective Commitment, Varavit Chinnapong
Master's Theses
Predicting employees' affective commitment to their organization continues to be of strong interest to researchers. Previous studies have examined the relationship between specific organizational levels (company, manager, group, individual) and affective commitment. However, there is a lack of research that has analyzed all four levels in one study. Therefore, the current study sought to evaluate the relationships between the four organizational levels and affective commitment. More specifically, the current study analyzed human resources practices as the company-level variables, transformational and transactional leadership as the manager-level variables, group cohesion as the group-level variable, and psychological safety at the individual level. The …
The Moderating Effect Of Leadership Adaptability On The Relationship Between Employee Adaptability And Job Performance, Justine Davis
The Moderating Effect Of Leadership Adaptability On The Relationship Between Employee Adaptability And Job Performance, Justine Davis
Master's Theses
The purpose of this study was to investigate the potential moderating effect of leadership adaptability on the relationship between employee adaptability and employee job performance. Previous research explored leadership adaptability as a mediator; however, there was a significant gap exploring leadership adaptability as a moderator. Participants were recruited via online social and personal networks. 125 participants completed a self-report survey consisting of items measuring employee adaptability, perceived manager adaptability and job performance. Results did not show perceived manager adaptability as a moderator of the relationship between employee adaptability and job performance. The results indicated that there were significant relationships between …
The Relationship Between Diversity Climate Perceptions And Organizational Citizenship Behavior And Work Engagement: The Mediating Role Of Overall Organizational Justice, Arika Nakajima Higgins
The Relationship Between Diversity Climate Perceptions And Organizational Citizenship Behavior And Work Engagement: The Mediating Role Of Overall Organizational Justice, Arika Nakajima Higgins
Master's Theses
Employees’ perceptions concerning their organization’s diversity climate have important implications for both the organization and the individual. Diversity climate research has traditionally focused on exploring the moderators of the relationship between diversity climate perceptions and the attitudinal outcomes of employees; however, research has neglected to examine behavioral outcomes and the potential mediators of the relationship. Therefore, the present study explored the indirect effects of overall organizational justice on the relationship between diversity climate perceptions and organizational citizenship behavior and work engagement. It was hypothesized that diversity climate perceptions would be positively related to organizational citizenship behavior and work engagement. It …
Inducing The Overview Effect Using Virtual Reality, Nhat Quang Le
Inducing The Overview Effect Using Virtual Reality, Nhat Quang Le
Master's Theses
Astronauts who return from space missions have reported and demonstrated a significant increase in their feelings of connection to humanity and the planet. This shift towards a more humanistic, global perspective in astronauts was termed the “overview effect” by White (2014). There is a lack of research on the overview effect despite the significant, positive changes in those who have experienced it. This study aims to provide empirical evidence of and a possible induction method for the overview effect. We hypothesized that it might be possible to induce the overview effect using virtual reality (VR). In the current study, 81 …
The Moderating Role Of Agreeableness And Conscientiousness On The Relationships Between Burnout And Withdrawal Behaviors, Nikoo Samee
Master's Theses
It has been shown that employees who experience burnout are more likely to engage in withdrawal behaviors, which are behaviors that harm the morale of employees and the bottom line of an organization. There has been some research on the moderating effect of situational variables (e.g., leadership style) on the relationship between burnout and withdrawal behaviors, but there is a lack of research on how personal characteristics may play a role in such relationships. The purpose of this study was to examine the moderating role of agreeableness and conscientiousness on the relationship between burnout and three withdrawal behaviors: lateness, absenteeism, …
The Moderating Effects Of Gender And Occupation On Age Discrimination In Hiring, Rachel Su Windsor
The Moderating Effects Of Gender And Occupation On Age Discrimination In Hiring, Rachel Su Windsor
Master's Theses
Over the years, ageism in the workplace has become an important topic. However, it remains unclear whether and how gender and occupation relate to age discrimination in hiring decisions. The current study addresses this issue by investigating job suitability ratings and selection decisions by comparing two hypothetical job applicants who differ in age (younger vs. older) and gender (male vs. female) for two occupations (software engineer vs. nurse) in two industries (high-tech and healthcare). This study employed a 2 x 2 x 2 incomplete mixed-factorial design, in which age was a within-subjects factor, and gender and occupation were between-subjects factors. …
The Mediating Role Of Work Engagement On The Relationship Between Perceived Supervisor Support And Turnover Intention, Addison Yeosock
The Mediating Role Of Work Engagement On The Relationship Between Perceived Supervisor Support And Turnover Intention, Addison Yeosock
Master's Theses
The purpose of the current study was to examine the mediating role of work engagement on the relationship between perceived supervisor support and turnover intention using the Jobs Demands-Resources (JD-R) model and the motivational processes of engagement as the theoretical framework. A total of 954 employees of a healthcare organization participated in an online survey. Results showed that work engagement partially mediated the relationship between perceived supervisor support and turnover intention. Perceived supervisor support was negatively related to turnover intention directly and indirectly through work engagement. Based on these findings, organizations should focus on strategies of increasing the job resource …
The Moderating Role Of Emotional Intelligence On The Relationship Between Job Resources And Employee Engagement, Amanda Lipson
The Moderating Role Of Emotional Intelligence On The Relationship Between Job Resources And Employee Engagement, Amanda Lipson
Master's Theses
The purpose of the current study was to examine the moderating role of emotional intelligence on the relationship between job resources (i.e., perceived supervisor support and autonomy) and employee engagement. Previous research has shown that these job resources are related to employee engagement. However, little attention has been paid to the possible moderators of this relationship. Therefore, this study aimed to bridge the gap in current literature by investigating how the relationship between job resources and engagement might change as a function of a personal resource (emotional intelligence). It was hypothesized that the positive relationship between job resources (perceived supervisor …
The Relationship Between Perceived Overqualification And Job Attitudes And Behaviors: The Moderating Role Of Psychological Empowerment, Emily Colleen Meyer
The Relationship Between Perceived Overqualification And Job Attitudes And Behaviors: The Moderating Role Of Psychological Empowerment, Emily Colleen Meyer
Master's Theses
It has been shown that employees who perceive to be overqualified in their roles are more likely to display negative attitudes and behaviors; however, little attention has been paid to the possible moderators of this relationship. Therefore, the present study proposed that psychological empowerment would moderate the relationship between perceived overqualification and job attitudes (affective commitment and careerist attitudes) and behaviors (counterproductive work behaviors). It was hypothesized that the relationship between perceived overqualification and these job attitudes and behaviors would be weaker for employees with higher levels of psychological empowerment than for employees with lower levels of psychological empowerment. Results …
