Impact Of Positive Psychological Capital On Employee Well-Being Over Time, James B. Avey, Fred Luthans, Ronda M. Smith, Noel F. Palmer

Department of Management: Faculty Publications

The recently recognized core construct of psychological capital or PsyCap (consisting of the positive psychological resources of efficacy, hope, optimism, and resilience) has been demonstrated to be related to various employee attitudinal, behavioral, and performance outcomes. However, to date, the impact of this positive core construct over time and on important employee well-being outcomes has not been tested. This study meets this need by analyzing the relationship between a broad cross-section of employees’ (N = 280) level of PsyCap and two measures of psychological well-being over time. The results indicated that employees’ PsyCap was related to both measures of well-being …

Everyday Sensegiving: A Closer Look At Successful Plant Managers, Anne D. Smith, Donde Ashmos Plowman, Dennis Duchon

Department of Management: Faculty Publications

The authors conducted in-depth interviews and on-site visits with successful plant managers to understand similarities in their management approaches. Across 11 different plants, representing nine different industries, the authors found each plant manager actively engaged in shaping how employees viewed the organization and its values through what the authors call “everyday sensegiving.” From themes inductively identified from the interviews and on-site visits, four central values—”Here, we value people, we value openness, we value being positive, and we value being part of a larger community”— were identified. In this article, the authors link everyday sensegiving of these middle managers and extend …

Perceiver Effects As Projective Tests: What Your Perceptions Of Others Say About You, Dustin Wood, Peter D. Harms, Simine Vazire

Department of Management: Faculty Publications

In three studies, we document various properties of perceiver effects—or how an individual generally tends to describe other people in a population. First, we document that perceiver effects have consistent relationships with dispositional characteristics of the perceiver, ranging from self-reported personality traits and academic performance to well-being and measures of personality disorders, to how liked the person is by peers. Second, we document that the covariation in perceiver effects among trait dimensions can be adequately captured by a single factor consisting of how positively others are seen across a wide range of traits (e.g., how nice, interesting, trustworthy, happy, …

What Do Conscientious People Do? Development And Validation Of The Behavioral Indicators Of Conscientiousness (Bic), Joshua J. Jackson, Dustin Wood, Tim Bogg, Kate E. Walton, Peter D. Harms, Brent W. Roberts

Department of Management: Faculty Publications

Typical assessments of personality traits collapse behaviors, thoughts, and feelings into a single measure without distinguishing between these different manifestations. To address this lack of specification, the current study develops and validates a measure that assesses a number of broad behaviors associated with the personality trait of conscientiousness (the Behavioral Indicators of Conscientiousness; BIC). Findings suggest that the lower-order structure of conscientious behaviors is mostly similar to the lower-order structure in extant trait measures. Furthermore, a daily diary method was used to validate the BIC against frequency counts of conscientious behavior. Overall, the results identify specific behaviors that conscientious individuals …

Relationship Between Positive Psychological Capital And Creative Performance, David S. Sweetman, Fred Luthans, James B. Avey, Brett C. Luthans

Department of Management: Faculty Publications

Despite considerable attention to the creative process and its relationship with personal characteristics, there is no published study focused directly on the relationship between the recently recognized core construct of psychological capital (PsyCap) and creative performance. Drawing from a large (N = 899) and heterogeneous sample of working adults, this study investigates PsyCap and its components (i.e., efficacy, hope, optimism, and resilience) as predictors of creative performance. Overall PsyCap predicted creative performance over and above each of the four PsyCap components. Theoretical and practical implications of these findings are considered.

How Emerging Market Firms Compete In Global Markets, Rajaram Veliyath, Lance Brouthers

Faculty and Research Publications

We posit that contexts in emerging markets are different from developed country contexts. These contextual differences necessitate the development and deployment of unique capabilities and strategies on the parts of companies operating there. While all emerging market countries are not uniform across all of the characteristics described below, there is a great deal of commonality on these conditions within the group of emerging market countries, by virtue of their similar stages of development. Thus, companies that develop their skill sets and products/services in one emerging market are likely to more easily be able to extend them to others. Conversely, there …

The Development And Resulting Performance Impact Of Positive Psychological Capital, Fred Luthans, James B. Avey, Bruce J. Avolio, Suzanne Peterson

Department of Management: Faculty Publications

Recently, theory and research have supported psychological capital (PsyCap) as an emerging core construct linked to positive outcomes at the individual and organizational level. However, to date, little attention has been given to PsyCap development through training interventions; nor have there been attempts to determine empirically if such PsyCap development has a causal impact on participants’ performance. To fill these gaps we first conducted a pilot test of the PsyCap intervention (PCI) model with a randomized control group design. Next, we conducted a follow-up study with a cross section of practicing managers to determine if following the training guidelines of …

An Analysis Of Factors That Influence The Success Of Women Engineering Leaders In Corporate America, Letha Joye Jepson

Antioch University Full-Text Dissertations & Theses

"One in 4 women entering the engineering profession leaves after age 30, while only 1 in 10 of their male counterparts does" (Perusek, 2008, p. 20). I was interested in analyzing the factors supporting women engineers’ leadership development and success. My particular focus was on women engineers in corporate environments—the personal characteristics needed for a successful career and the impacts of social support, career development, and the corporate culture on their career progression. The aspects of social support included the factors of family, friends, and significant others and the levels of supports during the woman’s career. The features of corporation …

Strategic Asymmetric Multicultural Alliances In Business, Anthony James Scriffignano

Antioch University Full-Text Dissertations & Theses

Global economics and other factors make it increasingly difficult for organizations to operate within the boundaries of one country in a rational way (e.g., leveraging best practices, profitable, achieving goals). In this study, I looked at strategic business alliances, transcending simple quid pro quo relationships to deliver ongoing partner value. I refined my study to multicultural relationships, having differing cultural identities (i.e., ideas, heritage, language, or demographics from differing geographies). Finally, I considered asymmetry (i.e., inequity in working relationship). Using a mixed-methodology design, I surveyed alliance participants and interviewed participants from selected alliances. A multi-case study addresses emergent themes of …

Expanding Leader Capability: An Exploratory Study Of The Effect Of Daily Practices For Leader Development, Simon Rakoff

Antioch University Full-Text Dissertations & Theses

Leadership is, at its essence, an influence relationship between people. Leaders are often thought of as those who are able to influence people to take actions oriented toward achieving specific goals and objectives. While many books have been written, and myriad scholarly research studies conducted enumerating countless personal characteristics, qualities, and skills of the exemplary leader, little has been done to understand and convey the ways in which an individual might go about cultivating these virtues; which are often said to include charisma, empathy, communication skills, and others. Through a multiple single-subject design, this research examines the individual-level effect of …

Linking Uses Of Management Control Systems With Strategic Capabilities And Business Level Strategies For Organizational Performance Evidence From The Sri Lankan Textile And Apparel Industry, Nirosha D. Kapu Arachchilage

Theses: Doctorates and Masters

This research investigates how the uses of Management Control Systems (MCS), namely, diagnostic use and interactive use, as moderating variables, influence the relationship between business (competitive) strategies (which are determined by strategic capabilities) and organizational performance. Simons’ levers of control model, Porter’s theory of generic competitive strategy and the Resource Based View (RBV) of strategy have been considered as the underpinning theories and models of the study in developing the theoretical framework and hypotheses. The theoretical framework consists of two strategic capabilities (low cost competency and uniqueness competency), two generic business strategies (cost leadership and differentiation), two uses of MCS …

Ontology-Based Information Extraction For Analyzing It Services, Amit Deokar, Sagnika Sen

Amit Deokar

Service Level Agreements (SLA) for multi-service Information Technology (IT) outsourcing contracts contain vast amounts of textual information. The SLAs provide details about a specific service, Key Performance Indicators (KPI) to measure its performance; as well as process elements, such as activities, events, and resources that are integral in achieving performance goals. However, KPIs and the process elements may be interrelated. The knowledge of such interrelationships is often tacitly present in the SLAs. The aim of our research is to extract this hidden information from IT service contracts and analyze them to empower customers of IT services to make better performance …

Hospital Capacity Planning For Efficient Disaster Mitigation During An Earthquake, Pengfei Yi, Santosh George, Jomon Aliyas Paul, Li Lin

Jomon Aliyas Paul

Hospitals are an integral part of a society’s critical functions designed to respond to man-made and natural disasters. Effective hospital capacity planning can significantly enhance the capability and effectiveness of treatment for emergency patients with injuries resulting from a disaster. Such information can be used for patient/ambulance routing, resource planning, and emergency operations management. In the current paper, we develop a generic simulation model that is capable of representing the operations of a wide range of hospitals given an earthquake disaster situation. Using results from our simulations, generalized regression equations are fitted to obtain steady-state hospital capacities. A parametric metamodel …

Models For Solving Emergency Room Crisis., Jomon Aliyas Paul, Kedar Sambhoos

Jomon Aliyas Paul

Emergency Departments (ED) across United States are distraught with issues like overcrowding, ambulance diversion, medical errors, patient left without being seen etc. The primary cause for all these interrelated problems is artificial variability that results mainly because of inaccurate severity estimation leading to inappropriate bed allocation and final disposition. To this effect, we propose Bayesian decision support tools that accurately classify new incoming patients into different severity types based on their chief complaints and at the same time assist doctors in subsequent diagnosis and disposition of patients. These tools are developed based on the decision making principles of attending physicians …

Business Failure Prediction Using Decision Trees, Adrian Gepp, Kumar Kuldeep, Sukanto Bhattacharya

Adrian Gepp

Accurate business failure prediction models would be extremely valuable to many industry sectors, particularly financial investment and lending. The potential value of such models is emphasised by the extremely costly failure of high-profile companies in the recent past. Consequently, a significant interest has been generated in business failure prediction within academia as well as in the finance industry. Statistical business failure prediction models attempt to predict the failure or success of a business. Discriminant and logit analyses have traditionally been the most popular approaches, but there are also a range of promising non-parametric techniques that can alternatively be applied. In …

Roads Or Radar: The Tradeoff Between Investments In Infrastructure And Forecasting When Facing Hurricane Risk, Eric Bickel, Seong Dae Kim

Eric Bickel

When faced with a significant risk, society must decide howmuch to invest in prediction and response. For example, in the face of hurricane risk how much should we invest in better forecasting versus increased evacuation speed? To address this need, we develop a Markov decision processes model to analyze the interaction between the emergency response system and the emergency forecasting system. The model shows the tradeoff between the two investments given a budget limit. In addition, the research indicates that the superiority of the investment changes sharply by the lead time.

Bayesian Inference For A Periodic Stochastic Volatility Model Of Intraday Electricity Prices, Michael S. Smith

Michael Stanley Smith

The Gaussian stochastic volatility model is extended to allow for periodic autoregressions (PAR) in both the level and log-volatility process. Each PAR is represented as a first order vector autoregression for a longitudinal vector of length equal to the period. The periodic stochastic volatility model is therefore expressed as a multivariate stochastic volatility model. Bayesian posterior inference is computed using a Markov chain Monte Carlo scheme for the multivariate representation. A circular prior that exploits the periodicity is suggested for the log-variance of the log-volatilities. The approach is applied to estimate a periodic stochastic volatility model for half-hourly electricity prices …
