A Mathematical Remodeling For Crop Portfolio Selection Under Limited Irrigation Resource, Li Zhang
A Mathematical Remodeling For Crop Portfolio Selection Under Limited Irrigation Resource, Li Zhang
S.C. Water Resources Conference
A mathematical model and optimization framework to aid farmers in selecting crop portfolios were proposed and discussed in (Bokhira et al. 2014; Chrispell et al. 2012). In this paper, we propose a refined mathematical model which reduces the number of constraints by nearly half while the number of decision variables is about the same. Also, the proposed model is easier to implement and maintain due to its generalized structure, and it provides more flexibility for us to expand the problem. Some key sensitive analysis is also provided.
Disability Status, Disability Type, And Training As Predictors Of Job Placement, Jessica Stahl
Disability Status, Disability Type, And Training As Predictors Of Job Placement, Jessica Stahl
All Dissertations
Human Capital Theory was used as a means to formulate predictions regarding the placement rates for disabled and non-disabled individuals who participated in job training programs at a non-profit agency in the Southeast. Research suggesting that disabilities are viewed as an economic liability by employers was reviewed, along with empirically based rejoinders to this stereotype. The first goal of this study was to address flaws in the existing categorization systems of disabilities, and to justify a categorization system that was more detailed than the typical psychological/physical disability distinction in the I/O and vocational rehabilitation literature (e.g., Ren, Paetzold, and Colella, …
The Influence Of Mindfulness During The Travel Anticipation Phase On Search And Choice Behaviors, Search And Choice Outcomes, And Trip Evaluations, Lorraine Taylor
The Influence Of Mindfulness During The Travel Anticipation Phase On Search And Choice Behaviors, Search And Choice Outcomes, And Trip Evaluations, Lorraine Taylor
All Dissertations
Anticipation is the first travel phase (Clawson & Knetsch, 1966) and consists of the vacation planning process. Tourists may exhibit varying levels of mindfulness during this phase. Mindfulness is associated with analytic decision making through a heightened sensitivity to one's environment and openness to new information (Langer & Moldoveanu, 2000). This study considered the influence that mindfulness during the travel anticipation phase has on: search and choice behaviors, search and choice outcomes, and trip evaluations. Analysis was also conducted to determine if there was a significant influence on the relationships based on the mediating effect of the amount of the …
Unifying Specific Climate Research With A Molar Climate Measure: A Situational Affordances Approach, Alice Brawley
Unifying Specific Climate Research With A Molar Climate Measure: A Situational Affordances Approach, Alice Brawley
All Theses
Organizational climate - briefly, the shared perceptions of a workplace - was originally studied as a molar concept, but this approach generally lacked focus and thus resulted in unmanageable measures. Organizational climate research has been subdivided into many areas of specific climate research focusing on particular organizational factors or outcomes, such as safety or customer service (Schneider, Ehrhart, & Macey, 2013). While the study of specific climates has been and remains worthwhile, recent literature in the area has called for a return to the molar or global conceptualization of organizational climate (Kuenzi & Schminke, 2009; Schneider et al., 2013). In …
Understanding The Antecedent Competencies Of Organizational Risk Management Capabilities, Jason Riley
Understanding The Antecedent Competencies Of Organizational Risk Management Capabilities, Jason Riley
All Dissertations
Hurricanes, tsunamis, and terrorism, are visible catastrophes that disrupt continuity for many organizations. Yet behind the curtain, there are multitudes of smaller events that cause supply chain disruptions. For example, quality issues, shipping delays, information system malfunction, demand spikes, and inventory mismanagement can quickly ripple from one supply chain to another. Practitioners work feverishly to contain small interruptions, while large disruptions can upset the supply chain for multiple organizations and depress an organization's financial valuation by up to 40%.
This study extends risk management thinking by exploring behavioral-based practices, rather than buffer inventory, redundant capacity, or financial countermeasures, as these …

Essays On Sourcing Decisions: A Behavioral Perspective, David Hall
Essays On Sourcing Decisions: A Behavioral Perspective, David Hall
All Dissertations
This dissertation examines how managers make and perceive supply chain governance decisions. A plethora of supply chain management literature suggests that managers will a priori choose a governance form that will manage risks while pursuing benefits. A number of theories have been used to inform this view: agency, resource-based view and transaction cost economics. Agency theory, the resource-based view and transaction cost economics all share the common assumption that a manager is considering both the risks and benefits of their decisions. In addition each of these perspectives assumes managers are boundedly rational. Taken together these two assumptions suggest managers have …
Essays On Service Improvisation Competence: Empirical Evidence From The Hospitality Industry, Enrico Secchi
Essays On Service Improvisation Competence: Empirical Evidence From The Hospitality Industry, Enrico Secchi
All Dissertations
This dissertation explores the service design antecedents and the performance outcomes of Service Improvisation Competence (Serv-IC) the ability of service employees to deviate from established processes and routines in order to timely respond to unexpected events, using available resources. Service operations and strategy research have strongly highlighted the importance of possessing flexibility in order to face the uncertainty derived from the interaction with the external environment (Tansik and Chase 1988, Eisenhardt and Tabrizi 1995, Brown and Eisenhardt 1998, Frei et al. 1999, Menor et al. 2001, Frei 2006). An important component of the ability of service rms to adapt to …

Essays On Product Recall Strategies And Effectiveness In The Fda-Regulated Food Sector, Tracy Johnson-Hall
All Dissertations
This dissertation consists of two complementary essays that investigate current product recall strategies in the Food and Drug Administration (FDA) regulated food sector. These studies address operations and supply chain factors that influence recall effectiveness with two theoretically-based, empirical approaches.
The first essay examines recall effectiveness as measured by time to recall, a proxy for potential consumer exposure to hazardous products (Hora, Bapuji and Roth, 2011) using duration analysis techniques. The unit of analysis is a recall event as documented by the product recall press release. Essay 1 addresses the following question: how do supply chain competencies related to integration …
Factors Influencing Nonprofit Leaders' Intention To Build Capacity, Kimberley Brown
Factors Influencing Nonprofit Leaders' Intention To Build Capacity, Kimberley Brown
All Dissertations
ABSTRACT
Examining attitudes, norms and behavioral control perceptions can aid in predicting the strength of a person's intentions to engage in any kind of major effort, including nonprofit capacity building, according to Aizen's Theory of Planned Behavior (Aizen, 1991, 2002a, 2006). The purpose of this research was to determine whether the attitudes, norms, and perceived behavioral control beliefs of 470 nonprofit leaders' past and future organizational capacity building had significance in explaining their stated intentions to build capacity. It also sought to determine what respondent and organization characteristics, the presence or absence of trust relationships, board governance practices, and organizational …
Information Technology (It) Identity: A Conceptualization, Proposed Measures, And Research Agenda, Michelle Carter
Information Technology (It) Identity: A Conceptualization, Proposed Measures, And Research Agenda, Michelle Carter
All Dissertations
With increasing embeddedness of information technologies (IT) in organizational processes, and services, individuals' long-term IT use has become instrumental to business success. At the same time, IS research has illustrated that under-utilization by end-users often prevents organizations from realizing expected benefits from their technology investments. Because individual use is the critical link between technology investments and enhanced organizational performance through IT, in recent years, information systems researchers have begun to focus attention on the post-adoption phases of technology assimilation. The overarching goal of this relatively new research stream is to understand factors that influence individuals' attempts to use IT to …

It-Business Strategic Alignment: Essays Examining Types Of Alignment And Their Relationship With Firm Performance, Jennifer Gerow
It-Business Strategic Alignment: Essays Examining Types Of Alignment And Their Relationship With Firm Performance, Jennifer Gerow
All Dissertations
While Information-Technology (IT)-Business Strategic Alignment (hereafter referred to as alignment) continues to be a topic of great concern to both researchers and practitioners alike, it is often misunderstood and, as such, many organizations find alignment difficult to achieve. In particular, alignment is often defined in many different ways, its operational measures are used inconsistently, and it is unclear how it can be attained. In this dissertation, we assert that researchers should include explicit references to the type of alignment under study, that adequate and consistent operational measures of each alignment type are necessary, and that we need a better understanding …
Understanding The Role Of Embeddedness In Shaping It Professional Behavior, Michael Dinger
Understanding The Role Of Embeddedness In Shaping It Professional Behavior, Michael Dinger
All Dissertations
This dissertation studies how information technology (IT) professionals become embedded and, in turn, how embeddedness influences organizational behaviors. Embeddedness refers to the extent to which an individual is attached to an organizational or professional setting. Traditionally, embeddedness is defined as having three components: social links, fit and sacrifice. We analyze the traditional conceptualization of embeddedness and identify weaknesses. As a result, we refine these three components to belongingness, fit and utility.
To deepen our understanding of embeddedness and its influence on organizational behavior, we develop a theory of embeddedness. We propose that embeddedness grows over time. As embeddedness increases, we …
Social Capital: Measurement, Dimensional Interactions, And Performance Implications, James Turner
Social Capital: Measurement, Dimensional Interactions, And Performance Implications, James Turner
All Dissertations
ABSTRACT
Recent OM literature conceptualizes social capital as being comprised of three inter-related dimensions: the relational dimension, the structural dimension, and the cognitive dimension. Existing research suggests that ocial capital offers firms the potential to leverage their interorganizational relationships to create sustainable advantage and superior performance opportunities for the firm.
However, despite the interest and attention of social capital theory among operations management (OM) and supply chain management (SCM) researchers, there is a surprising shortage of cohesive empirical research on social capital theory. The absence of reliable and valid empirical measures of social capital has limited OM researchers' ability to …
The Role Of Age In Technology-Induced Workplace Stress, Stefan Tams
The Role Of Age In Technology-Induced Workplace Stress, Stefan Tams
All Dissertations
Recent research shows that such Information and Communication Technologies (ICTs) as instant messengers can cause workplace interruptions, which lead to stress for employees and substantial productivity losses for U.S. organizations. Since the introduction of ICTs, workplace interruptions have evolved in both frequency and nature from irregular phone calls to a continuous stream of e-mail notifications and other electronic interruptions, mediated through a large number of technological devices that constantly beep and buzz. This trend of an increasing frequency of workplace interruptions closely relates to another workplace trend: the graying of the workforce, implying that the U.S. workforce is aging at …
Information Seeking Behavior: The Effects Of Relationalism On The Selection Of Information Sources, Chris Zimmer
Information Seeking Behavior: The Effects Of Relationalism On The Selection Of Information Sources, Chris Zimmer
All Dissertations
In a world where 'Google' is a verb, this research asks the question 'what influences an individual's decision to select one information source over another?' Previous works have discussed relational versus nonrelational information sources (Rulke, Zaheer, & Anderson, 2000). Other research focuses on the information quality (O'Reilly, 1982), source accessibility (Culnan, 1984, 1985), or source richness (Daft, Lengel, & Trevino, 1987; Daft & Macintosh, 1981) but all these prior works do not address the social aspects of information sources.
This research defines and develops the construct of relationalism which is reflective of the social aspects of information sources. An important …

Lean Manufacturing - An Integrated Socio-Technical Systems Approach To Work Design, Mohammed Raja
All Dissertations
Over the years, the manufacturing industry has witnessed a number of work design practices, based on different principles, which have significantly shaped the nature of work and have affected employees' behavior and performance. This study compares the socio-technical systems (STS) principles and lean production (LP) principles in to explore the potential for synergistic integration between the two. They are categorized according to the common overarching goals of these principles, and through a process of theoretical rationalization, these categories are operationalized into the work design practices of middle management support, social practices usage, and technical practices usage.
A model of work …
