Managers are responsible for disciplining those employees whose performance or conduct is sub-standard or inappropriate.

Show moreConflict between managers and employees is inevitable in any organization, whether public or private. Often, the source of the conflict is employee non-compliance. Managers are responsible for disciplining those employees whose performance or conduct is sub-standard or inappropriate. Therefore, the ability to effectively address employee non-compliance is an essential skill for all managers. Most employee discipline systems fall into one of three categories: traditional, progressive, and affirmative. Traditional systems were prevalent in the late-nineteenth and early twentieth centuries. An autocratic, demanding manager would mete out punishment to non-compliant employees both as an action against the employee and as a warning to other employees. Employees were often terminated for their first offense. With the advent of labor unionism and fair labor practices in the first half of the twentieth century, organizational leaders were required to develop more progressive employee discipline systems which protected employee "due process" and which allowed time and opportunity for improvement by the non-compliant employee. Progressive employee discipline systems are the most prevalent discipline systems in America's workforce today. These systems entail three or four steps, with each successive step usually resulting in more severe penalties for the same offense or more severe offenses. Progressive employee discipline allows the employee an opportunity to respond to non-compliance issues and to try to improve it to the extent required to maintain their position. A new employee discipline system, affirmative discipline, has gained adherents in the private sector primarily. Affirmative employee discipline systems do not use punishment to correct employee non-compliance but instead, ask managers to "coach" and "counsel" the non-compliant employee to better behavior and performance. Rehabilitating the employee's non-compliance is the primary goal of affirmative systems. The emphasis is not only upon the non-compliant employee, but on rehabilitating the "marriage" of non-compliant employee and direct supervisor. Little evidence exists to determine the extent to which progressive and affirmative employee discipline systems are being utilized in the modern organization. No evidence exists that indicates the prevalence of these systems in Florida's healthcare institutions. A survey-based analysis of the use of progressive and affirmative employee discipline systems in Florida's hospitals resulted in respondents indicating frequent utilization of formal progressive employee discipline systems. Designed in three or four steps, these progressive systems allow the employee to improve his/her behavior. Two common tools in progressive systems, the verbal warning and the performance counseling statement, are utilized frequently based upon those respondents surveyed. The use of affirmative employee discipline systems, on the other hand, is relatively rare. The use of written behavior contracts to elicit improved employee compliance is also quite rare. The vast majority of respondents appear to be unfamiliar with the use of written behavior contracts to elicit improved employee compliance.

Show moreThe present study investigated the impact of a multicultural self-awareness personal growth group on counselor education students (n = 94) and group leaders (n = 10) and their ethnic identity development scores, social-cognitive maturity levels, and presence of group therapeutic factors. Findings from the study identified no statistically significant differences in ethnic identity development and social-cognitive maturity scores between treatment group and comparison group participants, or as a result of multiple measurements throughout the semester. However, a statistically significant effect was identified for time (pre-test, M = 91.94, SD = 5.33; mid-semester, M = 90.32, SD = 6.43; post-test, M = 91.18, SD = 6.36) on social-cognitive maturity TPR scores for treatment group participants, Wilk's Lambda = .90, F (2, 63) = 3.39, p = .04, ?(&)#178; = .10. In addition, positive correlations were identified between ethnic identity development scores and group therapeutic factors in students participating in the multicultural personal growth groups: (a) Instillation of Hope, n = 63, r = .43, p = .00 (18.5% of the variance explained); (b) Secure Emotional Expression, n = 63, r = .39, p = .00 (15.2% of the variance explained); (c) Awareness of Relational Impact, n = 63, r = .47, p = .00 (22.1% of the variance explained); and (d) Social Learning, n = 63, r = .46, p = .00 (21.2% of the variance explained. Furthermore, a discussion of implications for counselor education and the scholarship of teaching and learning (SoTL) with graduate students are included.

Show moreA significant body of writing and rhetoric research focuses on the literate practices that reflect or construct the professional self, particularly in disciplines that rely heavily on the use of forms to categorize or identify customers, clients, or patients. Many of these studies examine the influence of discipline-specific genres on the creation of a professional self for healthcare practitioners. Occupational therapy, a nearly 100-year-old yet little understood profession, is significantly different from many other healthcare disciplines, in part, because the genres used by occupational therapists reflect the profession's careful attention to the whole life of a patient. These genres are built around an understanding of a patient's occupation as the object of the profession's activity system. (")Occupation(") (commonly defined too narrowly by those outside of the profession as (")work(")), is, quite simply, anything that meaningfully and purposefully occupies a person's time. This broadly defined object invites an expansive professional vision that includes the patient's life and history outside of a diagnosis. This study presents the narratives of four occupational therapists and the literate activities that inform their practice. Their voices, as excerpted in this case study, join a strong, ongoing conversation in writing and rhetoric studies about the relationship between genre and identity. Using the lens of activity theory, this is one account of a healthcare profession that pays unusual attention to patients' whole lives through genres that mediate shared agency between the caregiver and patient. It is also, however, the story of the ways in which this identity, as a uniquely occupation-based discipline, becomes obscured as therapists translate their work to genres created and controlled by other, more powerful activity systems.

Show moreReconfigurable logic or Field-Programmable Gate Array (FPGA) devices have the ability to dynamically adapt the computational circuit based on user-specified or operating-condition requirements. Such hardware platforms are utilized in this dissertation to develop adaptive techniques for achieving reliable and sustainable operation while autonomously meeting these requirements. In particular, the properties of resource uniformity and in-field reconfiguration via on-chip processors are exploited to implement Evolvable Hardware (EHW). EHW utilize genetic algorithms to realize logic circuits at runtime, as directed by the objective function. However, the size of problems solved using EHW as compared with traditional approaches has been limited to relatively compact circuits. This is due to the increase in complexity of the genetic algorithm with increase in circuit size. To address this research challenge of scalability, the Netlist-Driven Evolutionary Refurbishment (NDER) technique was designed and implemented herein to enable on-the-fly permanent fault mitigation in FPGA circuits. NDER has been shown to achieve refurbishment of relatively large sized benchmark circuits as compared to related works. Additionally, Design Diversity (DD) techniques which are used to aid such evolutionary refurbishment techniques are also proposed and the efficacy of various DD techniques is quantified and evaluated.Similarly, there exists a growing need for adaptable logic datapaths in custom-designed nanometer-scale ICs, for ensuring operational reliability in the presence of Process, Voltage, and Temperature (PVT) and, transistor-aging variations owing to decreased feature sizes for electronic devices. Without such adaptability, excessive design guardbands are required to maintain the desired integration and performance levels. To address these challenges, the circuit-level technique of Self-Recovery Enabled Logic (SREL) was designed herein. At design-time, vulnerable portions of the circuit identified using conventional Electronic Design Automation tools are replicated to provide post-fabrication adaptability via intelligent techniques. In-situ timing sensors are utilized in a feedback loop to activate suitable datapaths based on current conditions that optimize performance and energy consumption. Primarily, SREL is able to mitigate the timing degradations caused due to transistor aging effects in sub-micron devices by reducing the stress induced on active elements by utilizing power-gating. As a result, fewer guardbands need to be included to achieve comparable performance levels which leads to considerable energy savings over the operational lifetime.The need for energy-efficient operation in current computing systems has given rise to Near-Threshold Computing as opposed to the conventional approach of operating devices at nominal voltage. In particular, the goal of exascale computing initiative in High Performance Computing (HPC) is to achieve 1 EFLOPS under the power budget of 20MW. However, it comes at the cost of increased reliability concerns, such as the increase in performance variations and soft errors. This has given rise to increased resiliency requirements for HPC applications in terms of ensuring functionality within given error thresholds while operating at lower voltages. My dissertation research devised techniques and tools to quantify the effects of radiation-induced transient faults in distributed applications on large-scale systems. A combination of compiler-level code transformation and instrumentation are employed for runtime monitoring to assess the speed and depth of application state corruption as a result of fault injection. Finally, fault propagation models are derived for each HPC application that can be used to estimate the number of corrupted memory locations at runtime. Additionally, the tradeoffs between performance and vulnerability and the causal relations between compiler optimization and application vulnerability are investigated.

Show moreThe determination of semantic equivalence is an undecidable problem; however, this dissertation shows that a reasonable approximation can be obtained using a combination of static and dynamic analysis. This study investigates the detection of functional duplicates, referred to as semantic method clones (SMCs), in Java code. My algorithm extends the input-output notion of observable behavior, used in related work [1, 2], to include the effects of the method. The latter property refers to the persistent changes to the heap, brought about by the execution of the method. To differentiate this from the typical input-output behavior used by other researchers, I have coined the term method IOE-Behavior; which means its input-output and effects behavior [3]. Two methods are defined as semantic method clones, if they have identical IOE-Behavior; that is, for the same inputs (actual parameters and initial heap state), they produce the same output (that is result- for non-void methods, and final heap state).The detection process consists of two static pre-filters used to identify candidate clone sets. This is followed by dynamic tests that actually run the candidate methods, to determine semantic equivalence. The first filter groups the methods by type. The second filter refines the output of the first, grouping methods by their effects. This algorithm is implemented in my tool JSCTracker, used to automate the SMC detection process. The algorithm and tool are validated using a case study comprising of 12 open source Java projects, from different application domains and ranging in size from 2 KLOC (thousand lines of code) to 300 KLOC. The objectives of the case study are posed as 4 research questions:1. Can method IOE-Behavior be used in SMC detection?2. What is the impact of the use of the pre-filters on the efficiency of the algorithm?3. How does the performance of method IOE-Behavior compare to using only input-output for identifying SMCs?4. How reliable are the results obtained when method IOE-Behavior is used in SMC detection? Responses to these questions are obtained by checking each software sample with JSCTracker and analyzing the results.The number of SMCs detected range from 0 45 with an average execution time of 8.5 seconds. The use of the two pre-filters reduces the number of methods that reach the dynamic test phase, by an average of 34%. The IOE-Behavior approach takes an average of 0.010 seconds per method while the input-output approach takes an average of 0.015 seconds. The former also identifies an average of 32% false positives, while the SMCs identified using input-output, have an average of 92% false positives. In terms of reliability, the IOE-Behavior method produces results with precision values of an average of 68% and recall value of 76% on average.These reliability values represent an improvement of over 37% (for precision) of the values in related work [4]. Thus, it is my conclusion that IOE-Behavior can be used to detect SMCs in Java code with reasonable reliability.

I rely on original and appropriated imagery, as well as memories of loss and humor from my childhood in Alabama. Combining mixed media and sculptural elements has allowed me to investigate the subjects that interest me. I explore and artistically comment on these subjects through a mix of personal and culturally loaded imagery that records what I have either experienced or researched, and which I realize through the ironic use of non-traditional materials, such as sequins and rhinestones.My work examines stereotypes and my own beliefs about Southern good ole boys. I also reflect on elements of Southern hypocrisy, and I question long standing social practices with the help of historical and contemporary media sources.My exhibition is dedicated to my great uncle, who was murdered by his father, a preacher, during the Great Depression.

Show moreOn-road vehicles are a major source of transportation carbon dioxide (CO2) greenhouse gas emissions in all the developed countries, and in many of the developing countries in the world. Similarly, several criteria air pollutants are associated with transportation, e.g., carbon monoxide (CO), nitrogen oxides (NOx), and particulate matter (PM). The need to accurately quantify transportation-related emissions from vehicles is essential. Transportation agencies and researchers in the past have estimated emissions using one average speed and volume on a long stretch of roadway. With MOVES, there is an opportunity for higher precision and accuracy. Integrating a microscopic traffic simulation model (such as VISSIM) with MOVES allows one to obtain precise and accurate emissions estimates. The new United States Environmental Protection Agency (USEPA) mobile source emissions model, MOVES2010a (MOVES) can estimate vehicle emissions on a second-by-second basis creating the opportunity to develop new software (")VIMIS 1.0(") (VISSIM/MOVES Integration Software) to facilitate the integration process. This research presents a microscopic examination of five key transportation parameters (traffic volume, speed, truck percentage, road grade and temperature) on a 10-mile stretch of Interstate 4 (I-4) test bed prototype; an urban limited access highway corridor in Orlando, Florida. The analysis was conducted utilizing VIMIS 1.0 and using an advanced custom design technique; D-Optimality and I-Optimality criteria, to identify active factors and to ensure precision in estimating the regression coefficients as well as the response variable.The analysis of the experiment identified the optimal settings of the key factors and resulted in the development of Micro-TEM (Microscopic Transportation Emissions Meta-Model). The main purpose of Micro-TEM is to serve as a substitute model for predicting transportation emissions on limited access highways to an acceptable degree of accuracy in lieu of running simulations using a traffic model and integrating the results in an emissions model. Furthermore, significant emission rate reductions were observed from the experiment on the modeled corridor especially for speeds between 55 and 60 mph while maintaining up to 80% and 90% of the freeway's capacity. However, vehicle activity characterization in terms of speed was shown to have a significant impact on the emission estimation approach.Four different approaches were further examined to capture the environmental impacts of vehicular operations on the modeled test bed prototype. First, (at the most basic level), emissions were estimated for the entire 10-mile section (")by hand(") using one average traffic volume and average speed. Then, three advanced levels of detail were studied using VISSIM/MOVES to analyze smaller links: average speeds and volumes (AVG), second-by-second link driving schedules (LDS), and second-by-second operating mode distributions (OPMODE). This research analyzed how the various approaches affect predicted emissions of CO, NOx, PM and CO2. The results demonstrated that obtaining accurate and comprehensive operating mode distributions on a second-by-second basis improves emission estimates. Specifically, emission rates were found to be highly sensitive to stop-and-go traffic and the associated driving cycles of acceleration, deceleration, frequent braking/coasting and idling. Using the AVG or LDS approach may overestimate or underestimate emissions, respectively, compared to an operating mode distribution approach.Additionally, model applications and mitigation scenarios were examined on the modeled corridor to evaluate the environmental impacts in terms of vehicular emissions and at the same time validate the developed model (")Micro-TEM("). Mitigation scenarios included the future implementation of managed lanes (ML) along with the general use lanes (GUL) on the I-4 corridor, the currently implemented variable speed limits (VSL) scenario as well as a hypothetical restricted truck lane (RTL) scenario. Results of the mitigation scenarios showed an overall speed improvement on the corridor which resulted in overall reduction in emissions and emission rates when compared to the existing condition (EX) scenario and specifically on link by link basis for the RTL scenario.The proposed emission rate estimation process also can be extended to gridded emissions for ozone modeling, or to localized air quality dispersion modeling, where temporal and spatial resolution of emissions is essential to predict the concentration of pollutants near roadways.
