      Internet of Things (IoT) is a fast-growing technological trend, which is expected to revolutionize the world by changing the way we do things. IoT is a concept that encourages all the electronic devices to connect to the internet and interact with each other. By connecting all these devices to the internet, new markets can be created, productivity can be improved, operating costs can be reduced and many other benefits can be obtained. In IoT architecture, often sensors and aggregators collect data and send to a cloud server for analyzing via the traditional cloud-server model. This client-server architecture is not adequate to fulfill the growing requirements of IoT applications because this model is subjected to cloud latency. This research proposed a distributed computing model called Distributed Shared Optimization (DSO) to eliminate the delay caused by cloud latency. DSO is based on swarm intelligence where algorithms are built by modeling the behaviors of biological agents such as bees, ants, and birds. Mobile Ad-hoc Network (MANET) is used as the platform to build distributed computing. The infrastructure-less and leader-less features of MANET make it the ideal candidate to build IoT with swarm intelligence. To test the theory, this research also built a simulation program and conducted multiple simulations on both DSO and client-server models. The simulation data was analyzed by descriptive statistics and One-Way ANOVA. This research found that there is a significant difference in computing time between DSO and client-server models. Further, Multiple-Regression technique was conducted on DSO simulation data to identify the effect sensors and data had towards DSO computing time.
    • Diversity and Inclusion in The Information Technology Industry: Relating Perceptions and Expectations to Demographic Dimensions

      Wikina, Suanu Bliss
      The American society, especially the workplace, is becoming increasingly diverse in terms of race/ethnicity, culture, national origin, sexual orientation, familial status, age, religion, disability, and educational attainment (where there are people from different backgrounds and cultures the potential for suspicion and prejudices occur). This study examines diversity and inclusion in the information technology sector and assesses whether differences in group members perceptions and expectations are influenced by gender, race/ethnicity, position, and educational status. This study adopts a descriptive, quantitative approach utilizing a survey in the form of a questionnaire constructed using the Web-based survey software SurveyMonkey. This researcher designed a 12-item instrument administered to information technology (IT) professionals who are members of a national IT association. Statistical analyses, including descriptive statistics, correlation analysis, and t-tests were used to answer the research questions. It was found that perceptions and expectations of diversity and inclusion initiatives within the IT industry do not differ significantly by race/ethnicity, gender, education, and position. Details of the results, limitations, recommendations for future research, and applications for practice in organizations by human resources development professionals and technology managers are discussed.

      Robertson, Randolph B. (Cunningham Memorial library, Terre Haute,Indiana State University, 2017-12)
      This study investigates the impact of concurrent design on the cost growth and schedule growth of US Department of Defense Major Defense Acquisition Systems (MDAPs). It is motivated by the question of whether employment of concurrent design in the development of a major weapon system will produce better results in terms of cost and schedule than traditional serial development methods. Selected Acquisition Reports were used to determine the cost and schedule growth of MDAPs as well as the degree of concurrency employed. Two simple linear regression analyses were used to determine the degree to which cost growth and schedule growth vary with concurrency. The results were somewhat surprising in that for major weapon systems the utilization of concurrency as it was implemented in the programs under study was shown to have no effect on cost performance, and that performance to development schedule, one of the purported benefits of concurrency, was actually shown to deteriorate with increases in concurrency. These results, while not an indictment of the concept of concurrency, indicate that better practices and methods are needed in the implementation of concurrency in major weapon systems. The findings are instructive to stakeholders in the weapons acquisition process in their consideration of whether and how to employ concurrent design strategies in their planning of new weapons acquisition programs.
    • Effectiveness of Information Technology Infrastructure Library Process Implementations by Information Technology Departments within United States Organizations

      Persinger, Jon F.
      This research study examined whether the overall effectiveness of the Information Technology Infrastructure Library (ITIL) could be predicted by measuring multiple independent variables. The primary variables studied included the number of ITIL process modules adopted and the overall ITIL ―maturity level. An online survey was used to collect data from participating volunteers within the United States, and then analyzed to reveal any significant findings. The research showed a statistically significant positive relationship between overall maturity level and effectiveness, however the ability to predict effectiveness based upon the number of process modules adopted was inconclusive. Additionally, differences in module adoption from either the Service Support or Service Delivery process blocks were considered. The results suggested that process module adoption from the Service Support block has a somewhat stronger relationship to overall effectiveness than adoption from the Service Delivery block, though this finding should be viewed cautiously. Sample size and survey instrument limitations restricted the interpretation of the results.

      Arias, Scott (Indiana State University, 2014-12)
      Under the guidance of the United States Army Corps of Engineering Manual 385 (EM 385), the federal government has taken a stringent stance on construction safety. Using the mandated Occupational Safety and Health regulations and the 29 Code of Federal Regulation as a safety foundation, the EM 385 requires project-specific planning, continuous oversight and direct control of all safety activities. These mandates, required of every Department of Defense entity, focus on safety management not found within other federal agencies, in an attempt to reduce the number and severity of mishaps. This study looks for causation between the use of the EM 385 and the number and the severity of mishaps using three multiple regression analysis. The research population studied included construction contractors who performed work within various federal government agencies. The data was compiled using 2008 data that was merged using the federal construction spending data with mishap rates obtained from the OSHA Data Initiative (ODI). The explanatory variables considered in this research were EM 385 use, contractor size, project size, construction sector, pricing structure, solicitation procedure, OSHA region, disadvantaged business status and type of federal set-aside. The three dependent variables included the total case rate (TCR), the days away, restricted, and transferred (DART) rate, and the days away from work (DAFWII) rate. Analysis of this data revealed that there were no conclusive results showing a causal relationship between the EM 385 and a reduction in the number and severity of mishaps.
    • An Environmental Value Engineering (EVE) Analysis of the Environmental Impacts of Component Production for Traditional Wood-Framed and Structural-Insulated Panel Wall Systems

      Miller, Richard F. (Indiana State University, 2013-12)
      The building industry is a continually changing process, and for many years the traditional wall-framing approach has been used for residential and small commercial projects. In recent years, the introduction of new processes, procedures, and manufactured components have made an impact on the construction process and project. With the advent of these new technologies, come problems concerning the accounting for and determination of their environmental impact through analysis. In order to mitigate these problems and substantiate the environmental impact of manufactured components, it is necessary to implement a strategy, through analysis, that accounts for manufactured components and their impact to the life cycle of a built environment alternative. The purpose of this study was to investigate the material and component production phase using a traditional analysis methodology to determine the environmental impact and assess the influence these inputs and phases have on an Environmental value engineering (EVE) analysis. The study utilized the EVE analysis methodology to compare a traditional wood-framed system and those of a manufactured product, structural insulated panel systems (SIPs), in order to elucidate the component production phase, compare input impacts, identify the least environmental intrusive alternative wall system, and quantify a gap that existed in the EVE methodology. The statistical techniques used for this study were; comparative analysis, descriptive statistics, input source frequencies and impact data analysis of known and assumed values. The research findings indicate that the accounting of the component production phase for structural insulated panels increased the accuracy of the EVE analysis by 4.1% and that the separation of the manufacturing phases; material production, design, and component production incur a 11.2% more accurate accounting when compared with assumed or combined phases. The impact analysis results indicated that the material production phase imposed the highest influence for both alternative wall systems with inputs of 80% for traditional wood-framed systems and 84% for structural insulated panels. Input source results revealed that equipment, facilities, and materials have the highest impact for each wall system while the land and services (labor) were the lowest based on each wall alternative requirements. The results revealed that the manufactured system, structural insulated panel system, has the least environmental impact on the built environment. The study reinforced the need for developing strategies to incorporate the component production phase to more accurately portray the environmental impact in analysis.
    • Feasibility Study of Residential Grid-Connected Solar Photovoltaic Systems in the State of Indiana

      Al-Odeh, Mahmoud
      This study aims to measure the financial viability of installing and using a residential grid-connected PV system in the State of Indiana while predicting its performance in eighteen geographical locations within the state over the system’s expected lifetime. The null hypothesis of the study is that installing a PV system for a single family residence in the State of Indiana will not pay for itself within 25 years. Using a systematic approach consisting of six steps, data regarding the use of renewable energy in the State of Indiana was collected from the website of the US Department of Energy to perform feasibility analysis of the installation and use of a standard-sized residential PV system. The researcher was not able to reject the null hypothesis that installing a PV system for a single family residence in the State of Indiana will not pay for itself within 25 years. This study found that the standard PV system does not produce a positive project balance and does not pay for itself within 25 years (the life time of the system) assuming the average cost of a system. The government incentive programs are not enough to offset the cost of installing the system against the cost of the electricity that would not be purchased from the utility company. It can be concluded that the cost of solar PV is higher than the market valuation of the power it produces; thus, solar PV did not compete on the cost basis with the traditional competitive energy sources. Reducing the capital cost will make the standard PV system economically viable in Indiana. The study found that the capital cost for the system should be reduced by 15% - 56%.

      Bell, Christopher (Indiana State University, 2015-05)
      This study sought to determine if and to what extent strategy integration was related to the financial indicators profit margin ratio and inventory turnover for publically traded manufacturing organizations in Oklahoma. Current strategy theory states that the more thoroughly an organization adopts a given strategy the greater the effect will be on these financial indicators. Hence the need to more fully understand the extent and rates at which strategy integration effects these indicators. This study looked at perceived strategy integration scores for publically traded Oklahoma manufacturing organizations taken from June to August 2014 and financial indicators from 2012 and 2013. The perceived strategy integration scores were obtained via survey while the financial indicators were calculated using Section 10-K filings from the United States Securities and Exchange Commission (US SEC or SEC). Reliable financial information is not publically available for many private organizations, so, they were excluded from the study. Summary analysis of the data indicated that strategies were not in use in equal proportions with Niche Differentiation being most popular by far. Market focus appeared to be an indicator of inventory turnover standard deviation with Broad focus and Combination strategy groups having lower standard deviation. While the product focus appeared to indicate profit margin ratio range with Low Cost strategies having lower profit margins. After performing additional analysis it was found that performance enhancing technologies and other complicating factors may have had a larger impact than previously believed. A correlation was unable to be established for most strategies. For the Niche Low Cost Strategy a relationship was found where profit margins decreased 1.634% for each 1 point increase in perceived strategy integration score. It was also found that the Broad Differentiation Strategy it was found that inventory turns increased 0.7006 turns for every 1 point increase in perceived strategy integration score. No other strategies were found to have correlation coefficients that were statistically different from the null hypothesis. However, anecdotal evidence was found in support of several other of Porter’s theories.
    • Identifying Innovative Work Behaviors: An Inquiry Using Critical Incident Technique

      Peffers, Samuel N.
      Innovation is a driving force in economic activity and often considered essential for organizational health and growth; therefore, a better understanding of the employee behaviors that supervisors most frequently associate with employee innovativeness, innovative work behaviors, has the potential to be very beneficial. Although much has been written about it, most previous work has focused on behavior categories or dimensions without seeking to observe or understand how innovative work behavior is manifested in the workplace. Critical incident technique is a well-established and extensively applied method of inquiry for determining effective work role behaviors, but it has not previously been applied well to the study of innovative work behavior. This study applied critical incident technique to collect first hand behavior observations in the places where innovative work behavior occurs. A better understanding of the discrete behaviors associated with workplace innovation can assist Human Resources Development practitioners and educators in administering innovation focused training and development initiatives. The research presented in this dissertation indicates that what supervisors within organizations with a stated innovation orientation perceive as effective innovative work behavior can be summarized as four primary behaviors: generating ideas, recognizing problems or opportunities, acquiring ideas from sources external to the employee’s immediate work organization, and promoting ideas to others within the work organization.

      Blake, Petulia (Indiana State University, 2014-12)
      Sustainability is increasingly becoming an integral part of how organizations communicate their business operation to stakeholders. As it is common knowledge that organizations are more inclined to invest in programs that contribute to their bottom-line, this study presents an analysis of the relationship between corporate sustainability behaviors and their impact on financial performance. The sample size was 40 United States (U.S.) aerospace companies, selected from the “Top 100 Aerospace Companies” world-wide in a report produced by Candesic consulting firm in 2012. Of the 40 U.S. companies, 21 were found to provide some form of sustainability report. Quantitative and qualitative instruments were constructed to identify and measure the following sustainability behaviors: 1) Report versus Non-Reporting Status, 2) sustainability initiative integration (SII), 3) sustainability strategic integration (SSI), 4) trends in sustainability reporting, and 5) Global Reporting Initiative (GRI) versus Non-GRI status. Archival data such as sustainability reports and financial reports were used to compare the relationship between the five independent variables and the 5-year profit-margin ratio mean of the companies in the study. All financial information was obtained from Reuters, a financial and business news source. After retrieving and analyzing all the reports, it was found that there is no significant relationship between the sustainability behaviors identified and financial performance. Although, the sustainability reporting trends indicate a slight relationship between reporting start date and the 5-year average profit margin mean, this researcher understands that there may be other factors involved. Further, there appears to be some relationship among the independent variables Sustainability Initiative Integration (SII), Sustainability Strategic iv Integration (SSI) and GRI status. For instance, organizations that use the GRI metrics tend to provide a strong message indicating that sustainability is aligned with the business goals, which influence how they market and innovate products and services. The strength of this study is the qualitative components that will contribute to further understanding and development of corporate sustainability within a multidisciplinary context. The study created instruments primarily for the purpose of determining the impact corporate sustainability behavior has on financial performance while simultaneously providing new insight on new and changing organizational values and leadership communication. A corporate sustainability report is a comprehensive document that gives external and internal stakeholders’ information on how organizations are responding to social, economic, and environmental issues. This study illustrates how a sustainability report reflects an organization’s level of involvement in environmental, social, and economic issues which are relevant to any academic environment that seek to gain more understanding of how businesses pay attention to societal demands while striving to have competitive advantage in the global market.
    • Impact of ISO 9001 Certification on United States Firms’ Financial Performance

      Aba, Eli Kofi
      One of the greatest demands in our global economy that have compelled firms to invest increasingly in resources for the enhancement of their management practices is organizational competitiveness. Standards have played an increasingly important role in economic and market globalization. Studies on the financial impact of ISO 9001 on firms are still inadequate to make definitive conclusions on the financial impact of ISO 9001 on firms. Furthermore, there is no clear position on the financial benefits of ISO 9001 standard in literature. Therefore, the researcher investigated the impact of ISO 9001 certification on United States firms’ financial performance for a period of five years including one-year prior to certification, year of certification, and three fiscal years after certification. A sample of 397 firms that had received ISO 9001 certification from 1991 to 2002 was examined. Certified-firm and non-certified-firm operating performances were examined over the same period based on the ratio of pre-tax operating income to total assets (EBITA/TA). Wilcoxon signed-rank test was used to test for significant differences in operating performance between the firms. There was significant improvement performance from prior year to year of certification. The certified firms performed better in the five-year period than the non-certified and the matched-control firms.
    • Incorporating Lean Non-Value Added Variants into a Method of Determining Stakeholder Salience for First-Line Manager Decision Making

      Bader, Bruce H. (Cunningham Memorial library, Terre Haute,Indiana State University, 2017-12)
      This research brings together two streams of thought for first-line manager decisionmaking. The first is the quality system model, in particular, Lean operations. The second is Stakeholder Theory. Both streams have been identified as ways to improve value of the organization. Previous studies disagree regarding whether Lean and Stakeholder theory can work together. The potential problem of having a poor balance of Stakeholders and Lean waste is that exclusive focus on one may result in less awareness of the other, in which case value can be lost by the organization. This research investigates if both Lean waste and Stakeholder salience share a common language in the literature using data mining. This research surveys organizations that perceive themselves as Lean and have multiple diverse Stakeholders to determine whether Lean wastes and Stakeholder salience (priority) are considered the decision-making process. A Z-test compares proportions of Lean waste considered to proportions of Stakeholder salience. An ANOVA is done to see if organization type, position of a person within the organization, organization size, geographic location, or lean management maturity has an effect on the priority assigned to Stakeholder salience or Lean waste variants when making decisions. The final phase of this research is a proposed decision-making instrument that will weigh Stakeholder salience and Lean waste variants on an equitable level for First-line Managers’ decision-making. The major findings of this research are that Lean waste variants and Stakeholder salience are considered in decision-making but that Stakeholder salience is more important. This is iv independent of various factors. Stakeholder mapping using salience values adjusted for Lean waste provides a visually enhanced balanced approach allowing the decision-makers to know the impact of both, facilitating more precise input to their decision-making process. More precision in the decision-making process can lead to results that create improved value for the organization.

      Online learning has caused a seismic shift in higher education since its rise beginning at the turn of the century. A portion of that impact has been on the ascent of the part-time employee teaching online. Adjunct instructors account for the overwhelming majority of the faculty providing education to these online learners. Because an instructor’s performance impacts students’ learning and their resulting end of course evaluation has such a bearing upon that person’s employment, it is imperative to identify key performance indicators (KPIs) of employees teaching online. The problem addressed by this study was to determine the factors that affected a part-time online employee’s performance rating by their students within a higher education setting. More specifically, this study sought to identify key performance indicators for those teaching online part-time. Correlations and regression were conducted on institutional data covering 1295 fully online courses that occurred in 2016 at a regionally-accredited, private university. Potential key performance indicators studied were faculty threads posted per week, faculty employment longevity, faculty load, average course GPA, and class size. Three of those variables were statistically significant (p < 0.001) in individual correlations to an adjunct’s End of Course Survey score. Four of those factors were statistically significant (p < 0.001) in predicting students’ satisfaction of a part-time employee teaching online. The key performance indicators of part-time employees teaching online include faculty threads posted per week, faculty load, average course GPA, and class size. Implications and ideas for future research were discussed. iv ACKNOWLEDGEMENTS An undertaking such as this has one person as its author but many people that contribute to such a culminating project. Thank you to my Advisor and Chair, Dr. Cindy Crowder, for her encouragement, guidance, and status check-ins.

      Cardiovascular diseases are the leading cause of death in the United States. Advances in wireless technology have made possible the remote monitoring of a patient’s heart sensors as part of a body area network. Previous studies have suggested that stray wireless transmissions in the industrial, scientific, and medical (ISM) band cause interference resulting in packet loss in Bluetooth piconets. This study investigates the impact that wireless transmissions from residential microwave ovens have on the Bluetooth Low Energy (BLE) component of the body area network. Using a systematic data collection approach, two variables were manipulated. The distance between the microwave oven and the BLE piconet was varied from 0.5 meter to 5.0 meters at one-half meter increments. At each distance, the power level of the microwave oven was varied from the lowest power setting to the highest power setting. The two variables that were collected were the microwave interference generated by channel and the packet loss by channel. The results suggest more packet loss is due to the microwave oven’s power level than by the distance, the interference caused by the microwave oven affects all BLE channels equally, and the packet loss by channel is a good predictor of microwave oven interference. The significance of this study lies in providing beneficial information to the medical and digital communication industries concerning the causes and solutions to disruptions in the Bluetooth-enabled body area network devices in a very common situation. The results of this study may lend support for improvements and widespread use of body area network medical systems, which may have the benefit of better monitoring, more data, and reduced fatalities due to misdiagnosed heart conditions.

      Barrett, Scott T. (Cunningham Memorial library, Terre Haute,Indiana State University, 2017-12)
      This research study explored how college student leaders operationalize humility in their actions and what leads individuals to act with situational humility. There is a rise in narcissistic tendencies in college students (Twenge, Konrath, Campbell, & Bushman, 2008a, 2008b) and a decline in overall character traits (Burns, 2012; Hunter, 2000; Liddell & Cooper, 2012). Opposite the vice of narcissism sits the virtue of humility (Emmons, 2000; Exline & Geyer, 2004; Peterson & Seligman, 2004; Tangney, 2000). Using a grounded theory approach, the researcher looked to discover the process of humility development. Twenty six in depth interviews were conducted at three institutions. Each institution was a member of the Council of Christian Colleges and Universities and each participant identified as having a Christian belief system. Interviews were digitally recorded and transcribed. Transcriptions were coded using grounded theory method of open, axial, and selective coding. Based on the data collected three main themes emerged. Faith and humility go hand in hand, sense of self impacts humbling experiences, and the effect of relationships on humility. Through this research, the model of situational humility emerged grounded in the data. The model of situational humility describes what leads an individual to act with humility within a specific humbling experience. For these students, humbling experiences occurred when their sense of self (“I am an athlete,” “I get things done on time,” “I am a not racist”) did not line of up with their experience of the world (physical injury, failing to send necessary emails, making comments that were received as racial insensitive by a peer). Individuals then move to iv the point of change where they must decide how whether they will reorient their sense of self or actions or if they will not reorient and act with pride. In this point of change individuals were positively impacted towards humility by their Christian belief system, empathy, being in relationship, and interacting with others who were different from them. The implications of this research for institutional leaders who desire to grow humility in students include valuing how humility is seen as a virtue, growing empathy in students, and providing opportunities for students to be in relationship with others, specifically those who are different from them.
    • Organizations as Consumers of Human Capital Via Technology: A Policy Study of Information And Communication Technologies

      Zuppo, Colrain M.
      Organizations are consumers of human capital through technological means. Flexibility in work hours and locations can assist employee productivity; however, it can also foster a blurred distinction between work time and personal time (Robbins & Judge, 2007). Employees are given the tools to stay connected outside of a straightforward 40 hour work week in the name of enhanced productivity and/or flexibility with regard to their work arrangements. Organizational policies regarding ICTs have been limited to proscriptive measures (e.g. prohibiting installation of specific applications or downloads) as opposed to providing managerial parameters in the form of formal or informal policies.The purpose of this research was to provide a view of the multifaceted problem of managing technology (specifically ICTs) while balancing the needs of the humans within organizations who utilize those technologies. This dissertation investigated whether or not organizations have policies concerning employees’ constant connectivity to work during non-working hours through ICTs. This research also examined whether HR professionals, who would typically be involved in the formation of organizational policy, anticipated the formation and adoption of policies regarding employees’ usage of organizationally-provided/subsidized ICTs during non-working hours. Based upon data collected, a framework for a best-practices policy model was developed.
    • Post-Arrival Performance Interventions That Assist Expatriates’ Adjustment and Performance

      Wood, Evan D.
      This research examined the relationship between post-arrival performance interventions and the adjustment and performance of North American expatriates working and living in Hong Kong. The focus was on an integrated view of multiple post-arrival performance interventions in order to examine their combined impact. This research provides information to organizations regarding strategies to improve the adjustment and performance of expatriates. A multivariate design was used to describe the dynamics underlying the dimensions of adjustment and performance by indicating which interventions in combination might be more strongly associated with adjustment and performance. A questionnaire comprised of several existing constructs derived from the extant literature was developed and administered to those listed in the 2009/2010 American Chamber of Commerce Hong Kong membership directory. The interventions examined were integrated cross-cultural training, mentoring, role ambiguity, spouse and family support, and compensation. Four different multiple regression models were developed. The final general adjustment regression model showed a relationship with spouse and family support and role ambiguity. The final interaction adjustment regression model showed a relationship with role ambiguity, spouse and family support, compensation, and the control variable language fluency. The final work adjustment regression model showed a relationship with integrated cross-cultural training, mentoring, role ambiguity, spouse and family support, and compensation. Lastly, the final performance regression model showed a relationship with integrated cross-cultural training, mentoring, role ambiguity, spouse and family support, compensation, and language fluency. The results suggest the importance of multi-national corporations to consider post-arrival performance interventions in addition to pre-departure interventions. Specifically, two primary areas emerged with high significance. First, reducing role ambiguity has a significant relationship with all three adjustment constructs and performance. Second, the findings lend support to the concept of organizations providing additional support to the spouse and family as a means of increasing adjustment and performance of expatriates.
    • Processing Research snd Development of ‘Green’ Polymer Nanoclay Composites Containing a Polyhydroxybutyrate, Vinyl Acetates, and Modified Montmorillonite Clay

      McKirahan, James N. Jr.
      The purpose of this research was to determine the feasibility of direct melt-blending (intercalation) montmorillonite nanoclay to polyhydroxybutyrate along with vinyl acetate, at different weight percentages, to enhance plasticization using typical plastic processing equipment and typical processing methodology. The purpose was to determine and compare the specific mechanical properties of tensile strength and flexural strength developed as a result from this processing. Single screw and twin screw extrusion, Banbury mixer compounding, and compression molding were used to intercalate montmorillonite, and for sample preparation purposes, to test tensile and flexural strength of the resultant polymer clay nanocomposites (PCN). Results indicate Polyhydroxybutyrate and Ethylene vinyl acetate, and weight percentages of 70%, 65% and 60% PHB, and 15%, 20%, and 25% of EVA, respectively, influenced mechanical properties. The resultant materials remained in a mostly amorphous state. The nanoclay, at specific weight percentage of 10%, acted as an antimicrobial and preservative for the materials produced during the research. The intention of the research was to promote knowledge and understanding concerning these materials and processes so technology transfer regarding the use, mechanical properties, manufacture, and process ability of these bio-friendly materials to academia, industry, and society can occur.
    • Quality System for A Distance Doctoral Consortium: Determination and Analysis of Specific Indicators

      Chandler, Mark R.
      The problem for this research was that there were no identified and confirmed quality system model attributes for a successful online technology management doctoral consortium. The research extended existing research, and utilized a delphi panel to develop the attributes of a quality system model for a successful online doctoral consortium. The attributes of a quality system were developed by a three round delphi procedure and were used to develop a survey to determine perceived quality system differences among faculty, Ph.D. graduates, and current Ph.D. students associated with the Indiana State University (ISU) at Terre Haute Technology Management Ph.D. Consortium program. A proposed graphical quality system model capable of supporting the attributes of an online doctoral consortium was developed and utilized with the study and survey. Hypotheses testing and statistical analysis of the online survey were done to determine perceived quality system differences among faculty, Ph.D. graduates, and current Ph.D. students associated with the ISU Technology Management Ph.D. Consortium program. The research has indicated that there is a significant difference in the level of agreement the faculty expressed with regards to the ISU Technology Management Ph.D. Consortium in comparison to two other major Ph.D. consortium groups, the graduates and the students. While there was statistical evidence of differences in the three groups of faculty, graduates and students in the ISU Technology Management Ph.D. Consortium program, it was relatively minor. Twelve of the 63 quality indicators from the survey show some type of statistically significant difference in paired combination of faculty-student, faculty-graduate, student-graduate.

      Ramage, Michael (Cunningham Memorial Library, Terre Haute, Indiana State University., 2017-12)
      Ever since the first telegraph, a technology management challenge has existed to expand the availability of communication services farther into rural and unserved areas, while maintaining the affordability of those services to residential users. Over the years, that challenge has transformed from telegraph to broadband communications or high-speed Internet access. The challenge of affordable expansion of broadband services is seen all across the United States including the Commonwealth of Kentucky. This study examined the extent to which community and provider-related supply and demand factors among last mile residential fixed broadband service areas impact the nonpromotional advertised price of last mile broadband service throughout the 120 counties in the Commonwealth of Kentucky. The potential factors included population density, unemployment rate, provider count, broadband availability, middle mile, actual broadband speeds, technology deployed, provider type, maximum advertised download speeds, and maximum advertised upload speeds, with a goal to reveal if any have a correlation to the actual price of broadband seen by end users. In addition, this study attempted to create a model based on the significantly correlated factors. Utilizing Pearson correlation and multiple regression analysis, this study found five variables with a significant correlation to the dependent variable, price per megabit, including a slight negative correlation with the count of middle mile providers, slight positive correlation with the technology deployed, slight negative correlation with the provider type, strong negative v correlation with the download speed tier, and strong negative correlation with the upload speed tier. Finally, a model was created to predict the price per megabit of broadband with three variables, technology used, provider type, and a joint variable representing the download and upload speeds tiers.
