Examining The Effects Of Fatigue On Decision-Making In Nursing: A Policy-Capturing Approach, Laura Mcclelland

All Dissertations

Some previous research has focused on better understanding factors that influence nurses' decision-making; however, previous research has not used policy-capturing as a methodology to examine the impact of fatigue on registered nurses' decision-making. The purpose of the current study was to examine whether the fatigue of working a 12-hour day shift influenced a sample of registered nurses' decision-making. Participants consisted of 69 registered nurses working a 12-hour day shift from 7 AM to 7 PM at a large southeastern hospital. The participants completed a general questionnaire and a policy-capturing questionnaire at the beginning and at the end of a 12-hour …

Personality Predictors Of Motivation To Lead, Tracey Tafero

All Dissertations

In recent years, there has been a renewed interest in understanding the relationship between personality traits and leadership. Recent research suggests that some personality variables are related to leadership. However, research has rarely examined the process by which personality may impact leadership. This study explores the relationship between personality and motivation to lead, a proposed intervening variable between personality and leadership. In addition, this study looks at both broad and narrow measures of personality as predictors of motivation to lead. The current study both replicates and extends the findings of Chan & Drasgow (2001). Results reveal that facet-level personality scales …

Organizational Recruitment Web Sites: The Influence Of Web Site Aesthetics On Initial Affective Reactions To The Site And Subsequent Attraction To The Organization, Rebekkah Wills

All Theses

The present study examined the potential relationship between specific characteristics of organizational recruitment web sites and applicant attraction to the organization. Cober, Brown, Keeping, and Levy (2004) proposed a conceptual model that suggests web site aesthetics influence the applicant's attitude toward the web site which in turn influences applicant attraction. The current study provides a partial test of this model by examining web site aesthetics, prior attitudes toward the organization, initial affective reactions to the web site, perceptions of web site usability and post-viewing attitudes toward the site and the organization. Participants (N = 159) included undergraduate students using the …

An Evaluation Of The Impact Of Computerized Physician Order Entry On Medical Errors, Shannon Loewy

Masters Theses

The purpose of the present study was to examine the effects of a computerized physician order entry (CPOE) system on medication error. The study took place in a 343-bed hospital in the pediatrics inpatient unit. During baseline, participants placed medication orders in the same manner that they always had, handwriting them on a specific form and handing the form to the unit clerk who then faxed the order to the pharmacy. In the CPOE phase, participants used the computerized system to place orders, which were electronically sent to the pharmacy. The primary dependent variable was errors made during physician medication …

The Validity Of Assessment Centres For The Prediction Of Supervisory Performance Ratings: A Meta-Analysis, Eran Hermelin, Filip Lievens, Ivan T. Robertson

Research Collection Lee Kong Chian School Of Business

The current meta-analysis of the selection validity of assessment centres aims to update an earlier meta-analysis of assessment centre validity. To this end, we retrieved 26 studies and 27 validity coefficients (N=5850) relating the Overall Assessment Rating (OAR) to supervisory performance ratings. The current study obtained a corrected correlation of .28 between the OAR and supervisory job performance ratings (95% confidence interval .24 < =rho < =.32). It is further suggested that this validity estimate is likely to be conservative given that assessment centre validities tend to be affected by indirect range restriction.

Creating Alternate In-Basket Forms Through Cloning: Some Preliminary Results, Filip Lievens, Frederik Anseel

Research Collection Lee Kong Chian School Of Business

Research on constructing alternate forms of assessment center exercises is very scarce. This study examines the effectiveness of a cloning procedure (incident isomorphic approach) for developing alternate forms of a computerized in-basket. In this approach, original and alternate items are essentially similar (they are based on the same critical incident), while being superficially different (they are situated in a different context). Results showed there was no significant difference between the overall in-basket score across the alternate forms. In addition, these overall scores correlated .66, with projected estimates for the full in-basket approaching .80. Implications and limitations of the use of …

The Effects Of Feedback On The Accuracy Of Completing Flight Checklists, William G. Rantz

Masters Theses

This study examined whether pilots completed airplane checklists more accurately when they received post-flight graphic and verbal feedback. Participants were 8 college student pilots with instrument rating. The task consisted of flying flight patterns using a Personal Computer Aviation Training Device. The main dependent variable was the number of checklist items completed correctly per flight. A multiple baseline design across pairs with reversal was used. During baseline, the average number of correctly completed items per flight varied considerably across participants, ranging from 21 to 39 out of 40. It increased to near perfect levels for all participants after they were …

Social Influences On Organizational Attractiveness: Investigating If And When Word Of Mouth Matters, Greet Van Hoye, Filip Lievens

Research Collection Lee Kong Chian School Of Business

Previous recruitment studies have treated potential applicants as individual decision makers, neglecting informational social influences on organizational attractiveness. The present study investigated if and under what conditions word-of-mouth communication matters as a recruitment source. Results (N = 171) indicated that word of mouth had a strong impact on organizational attractiveness, and negative word of mouth interfered with recruitment advertising effects. Word of mouth from a strong tie was perceived as more credible and had a more positive effect on organizational attractiveness. For potential applicants high in self-monitoring, word of mouth had a stronger effect when presented after recruitment advertising. Finally, …

Workplace Cognitive Failure As A Mediator Between Work-Family Conflict And Safety Performance, Rachel Jane Daniels

Dissertations and Theses

The main goal of this thesis was to examine the effects of family-to-work conflict on safety performance. Data were collected from a sample of 134 employees, consisting primarily of construction workers. Results found that levels of conflict from the family role to the work role negatively affected participants' workplace cognitive failure, or cognitively based errors that occur during the performance of a task that the person is normally successful in executing. Workplace cognitive failure, in turn, was a significant predictor of levels ofsafety performance, both employees' compliance with safety procedures and the extent to which they participated in discretionary safety-related …

Detecting Malingering On The Mmpi-2: An Examination Of The Utility Of Combining The Validity Scales In A Non-Compensatory Model, Thomas James Burke

Masters Theses & Specialist Projects

The MMPI-2 is the most commonly used self-report measure for the assessment of psychopathology in forensic and psychiatric disability assessments (Bacchiochi & Bagby, 2006; Bagby, Marshall, & Bacchiochi, 2005). The MMPI-2 includes a variety of validity scales designed to detect content responsive faking (e.g., faking good or faking bad) as well as content nonresponsivity (randomly responding). The present study was conducted to determine whether a combination of validity scales to detect malingering of a psychotic disorder in a non-compensatory model would be more or less effective than using only a select few of the validity scales in a compensatory model. …

Creating Conflict: Antecedents Of Workplace Incivility, Megan Preston

Masters Theses & Specialist Projects

Incivility is defined as rude and discourteous behavior or displaying a lack of regard for others. As indicated by prior research (e.g., Pearson, Andersson, & Porath. 2000), the frequency and conscquences of uncivil behavior may result in a decline in psychological well-being, reduced job satisfaction, decreased organizational commitment, and increased turnover. However, much of the research to date has examined the relationship between personally experienced incivility and an assortment of job outcomes (Andersson & Pearson, 1999; Cortina et al., 2001; Pearson et al., 2000). The current study is distinct in that it addressed some of the potential factors that are …

Dishonorable Treatment: Workplace Incivility, Cultures Of Honor, And Work Outcomes, Scott Kelley

Masters Theses & Specialist Projects

Workplace incivility is defined as rude and discourteous behavior that takes place in a work setting. Research shows that this type of behavior can negatively affect the well-being of employees who are the targets. However, the impact of workplace incivility may differ from person to person. One variable that may play a role in how workplace incivility affects an individual is U.S. region and whether or not they are located in a culture of honor. In cultures of honor, such as the Southern U.S. region, individuals are theorized to be especially sensitive to insults or challenges to their reputation. Using …

Multilevel Methods: Emergent Issues And Future Directions In Measurement, Longitudinal Analyses And Non-Normal Outcomes, Paul D. Bliese, David Chan, Robert E. Ployhart

Research Collection School of Social Sciences

The study of multilevel phenomena in organizations involves a complex interplay between methods and statistics on one hand and theory development on the other. In this introduction, the authors provide a short summary of the five articles in this feature topic and use them as a platform to discuss the broad need for work in the two areas of (a) multilevel construct validation and measurement and (b) statistical advances in variance decomposition. Within these two broad frameworks, the authors specifically discuss, first, the need to continue moving beyond notions of isomorphism in developing and testing aggregate-level constructs. Second, they discuss …

Motivation And Performance In Computer Science: Test Of An Integrative Theory, Katherine A. Selgrade

Psychology Theses & Dissertations

The purpose of this study was to design and empirically test a parsimonious integrative motivation theory. The theory integrates aspects of expectancy theory, social cognitive theory, goal-setting theory, and commitment theory. The theory was tested with 170 undergraduate, students in an introductory computer science (CS) course.

The study tested relationships among the following variables: CS self-efficacy, mathematics ability, affective commitment to the CS class, goal orientation, effort, and performance. The study also tested the interactive effects of effort and ability on performance. Structural equation modeling was used to test the measurement model and a series of nested structural models. Findings …

Psychology Theses & Dissertations

The purpose of this research was threefold: (1) Present the a-b SDT model as an alternative framework to overcome the limitations of the underlying SDT model and the traditional measures of sensitivity and criterion setting, (2) Provide empirical support to validate the adequacy of the a-b SDT model, and (3) Conduct a Monte Carlo Study to compare and contrast the strengths and weaknesses of both the traditional and the a-b SDT models across the full spectrum of response values with the goal of providing researchers and practitioners with recommendations regarding the adequacy of each model. The results from this research …

It's Not So Hard To Say Goodbye, M. Thulasidas

Research Collection School Of Computing and Information Systems

Staff retention is a major problem in the job market here. Our economy is doing well; our job market is red hot. As a result, new job offers are becoming more irresistible. At some stage, someone you work closely with — be it your staff, your boss or a fellow team member — is going to hand in that dreaded letter to the human resource (HR) department. Handling resignations with tact and grace is no longer merely a desirable quality, but an essential corporate skill today.

Asymmetric Discounting In Intertemporal Choice: A Query Theory Account, E. U. Weber, E. J. Johnson, K. F. Milch, Hannah H. Chang, J. C. Brodscholl, D. G. Goldstein

Research Collection Lee Kong Chian School Of Business

People are impatient and discount future rewards more when they are asked to delay consumption than when they are offered the chance to accelerate consumption. The three experiments reported here provide a process-level account for this asymmetry, with implications for designing decision environments that promote less impulsivity. In Experiment 1, a thought-listing procedure showed that people decompose discount valuation into two queries. Whether one considers delayed or accelerated receipt of a gift certificate influences the order in which memory is queried to support immediate versus delayed consumption, and the order of queries affects the relative number of patient versus impatient …

More Than A Mean: Broadening The Definition Of Employee Performance, Amanda M. Baugous

Doctoral Dissertations

The detrimental impact of performance variation within the mechanics of an organizational process is well established within the field of Operations Management. Furthermore, determining the causes of and resolutions for variability in the performance of system mechanisms has become a key focus for improving organizational performance (Womack & Jones, 1996). This dissertation extends this research as it examines the prevalence and nature of human performance variability within organizations, its relationship with individual mean work performance, and its impact on individual- and group-level performance within a manufacturing context. Moreover, this study investigates the relationships between individual difference variables (conscientiousness, cognitive ability, …

Shared Leadership: A Social Network Analysis, Erika Engel Small

Doctoral Dissertations

Current leadership theory and research has centered on the attributes, behaviors, and relationships of a single leader. However, researchers now recognize the team as an alternative source of leadership. Theories of shared leadership propose that leadership is a process that can be shared among team members, and that this behavior is beneficial to team performance. The purpose of this study was not only to examine the performance benefits of shared leadership, but also to explore factors that may facilitate its development. Moreover, a social network analysis was used to measure the distribution of leadership among team members and the degree …

Income, Scheduling Flexibility, And Diversity Policies: An Experimental Investigation Of Recruiting Older Workers, Holly Geldhauser

All Theses

A number of surveys have tapped the interests of older employees as a way to understand the factors that encourage extended employment (Bass, 1995; Sterns, 1998). The current research has two purposes. The first is an applied goal; to determine the organizational factors that are most attractive to older workers seeking employment. The second purpose is to investigate the predictive strength of these variables through a controlled experimental design rather than using survey methodology. We chose to examine the importance of pay, work flexibility, and diversity policies as determinants of interest in the return to work among white collar employees. …

Newcomer Adjustment During Organizational Socialization: A Meta-Analytic Review Of Antecedents, Outcomes, And Methods, Talya N. Bauer, Berrin Erdogan, Todd Bodner, Donald M. Truxillo, Jennifer S. Tucker

Business Faculty Publications and Presentations

The authors tested a model of antecedents and outcomes of newcomer adjustment using 70 unique samples of newcomers with meta-analytic and path modeling techniques. Specifically, they proposed and tested a model in which adjustment (role clarity, self-efficacy, and social acceptance) mediated the effects of organizational socialization tactics and information seeking on socialization outcomes (job satisfaction, organizational commitment, job performance, intentions to remain, and turnover). The results generally supported this model. In addition, the authors examined the moderating effects of methodology on these relationships by coding for 3 methodological issues: data collection type (longitudinal vs. cross-sectional), sample characteristics (school-to-work vs. work-to-work …

The Relationship Between Uncertainty And Desire For Feedback: A Test Of Competing Hypotheses, Filip Anseel, Filip Lievens

Research Collection Lee Kong Chian School Of Business

The relationship between uncertainty and desire for feedback was investigated in 2 studies. Results of Study 1 showed support for a curvilinear relationship. People were interested in feedback at high and low levels of uncertainty, as opposed to moderate levels of uncertainty, indicating the activation of both uncertainty reduction and self-verification motives. In Study 2, the curvilinear relationship with uncertainty was replicated for indirect feedback-seeking behavior. In contrast, we found a negative relationship between direct feedback seeking and uncertainty, moderated by certainty orientation. People seemed more motivated by self-verification vs. uncertainty reduction strivings, depending on their certainty orientation. These findings …

The Effects Of A Still-Photo Computer Module Without Feedback On Ergonomic Behaviors, Rhiannon M. Fante

Masters Theses

The purpose of the present study was to examine the effects of a still-photo computer training module without feedback on safe positioning of individuals performing an assembly task and a lifting task using a multiple baseline design across behaviors and tasks. The study took place in an analogue office setting and participants were 6 college students. The dependent variable was the percentage of observations scored as safe and each session was recorded via a hidden camera. During each session, participants completed a 5 minute assembly task followed by 2 lifts and this task sequence was repeated a minimum of four …

Making Exit Interviews Useful To A Correctional Agency, Marian Layman, Laura Farris, Roni Reiter-Palmon, Erin Gallagher, Shawna Williams

Psychology Faculty Publications

Exit interviews serve as a tool to uncover departmental characteristics and areas in which departmental change should occur,¹ and they are effective in gathering information from departing employees regarding impressions and experiences in their department.² Ultimately, the goal of using exit interview questionnaires is to obtain objective information, increase efficiency of the interview process and evaluate aspects of the department through data analysis.³

The Nebraska Department of Correctional Services (DCS) contracted with the Center for Applied Psychological Services (CAPS) at the University of Nebraska at Omaha to evaluate the reasons for personnel voluntarily leaving their jobs. This …

An Identity Approach To Understanding Diversity, Inclusion And The Work-Family Interface, Rebekah A. Cardenas

Psychology Theses & Dissertations

The salience of one's ethnic identity, the subjective importance of that identity in one's life, was hypothesized to impact the extent to which inclusion predicts work-related outcomes (i.e., strain-based work-family conflict, work-family enrichment, job satisfaction and job stress) among 225 working women. Women who felt included at work (i.e., those who can participate, have influence and can "be themselves") were predicted to experience positive work-related outcomes. Further, belongingness at work was predicted to interact with ethnic identity salience to impact work-related outcomes for working women. Hierarchical linear regression analyses indicated that inclusion was significantly associated with positive work-related outcomes; yet, …

Methods Of Detecting Differential Item Functioning: A Comparison Of Confirmatory Factor Analysis Methods, Jenny Chia Yi Kuang

Psychology Theses & Dissertations

The present Monte Carlo study compared four confirmatory factor analysis (CFA) methods for detecting differential item functioning (DIF). The four methods were the noniterative and iterative mean and covariance structure analysis (MACS) methods, the modification index (MI) method, and the modification index-divided sample (MI-divided) method. Reference and focal groups responded to 12 items with 3 of the 12 items designed to exhibit DIF. Sample sizes of 250 and 500 were examined. In addition, three types of DIF were examined: DIF on loadings, DIF on thresholds, and DIF on both loadings and thresholds. Results indicated that for sample size 250, all …

Performance In Non-Face-To-Face Collaborative Information Environments, Brooke Schaab, J. Douglas Dressel, Mark A. Sabol, Andrea L. Lassiter

Psychology Department Publications

Using technology to obtain and process information requires training not only in human-computer interaction but also in human-human-computer (collaborative) interaction. Warfighters must not only develop their own situational awareness (SA), they must understand each others’ SA (Pew, 1995). This common ground is what each collaboration participant assumes about the others to ensure effective interactions (Ross, 2003; Wellons, 1993). Communication is key. Collaborators must coordinate and share information. Collaboration influences military operations at all levels. Technical interoperability is not enough to produce the synchronization required.
