• Predicting schools' performance in the state examinations : a model for Shaba province in Zaire

      Maloba, Ngoba (2009-08-26)
      The purpose of the study were (1) to ascertain for Literature major, Mathematics-Physics major, and General Pedagogy major, the significance of the relationship between the school's performance in each required course and their overall performance in the State Examinations; (2) to investigate for each major the significance of the relationship between the school's performance in all the required courses and their overall performance in the State Examinitations; (3) to develop for each major, a prediction equation to be used to predict school's performance in the State Examinitations; and (4) to analyze the degree of concordance, across teh three majors, in the ways courses common to them correlated with the State Examinations. A total of 58 rural and urban schools from Shaba Province were used in this study. Twelve offered Literature major and presented 275 candidates, sixteen offered Mathematics-Physics major and had 300 candidates, and twenty-eight offeredd General-Pedagogy major with 935 candidates. All these schools participated in the State Examinations in June 1976. A correlation matrix was developed for each major, using the Statistical Package for the Social Science (S.P.S.S). In this matrix each variable was compared singly with the other variables. Stepwise multiple regression analyses were completed for each major, in order to identify courses contributing significantly to the school's performance in the State Examinations. The results of these analyses were used to develop, for each major, an equation to be used to predit school's performance in the State Examinations. A multiple correlation coefficient was computed for each major, to test for the signigicance of the relationship between the school's performance in all the required coursed and their overall performance in the State Examinations. A kendall's coefficient of concordance was computed and its significance tested. The following findings were established from the analyses: 1. In each major, certain required courses contributed significantly to school's performance in the State Examinations. 2. The overall correlation in each major, between the school's performance in all the required courses and their performance in the State Examinations was significant. 3. A prediction equation was developed for each major. 4. The courses common to the three majors did not contribut to the school's performance, in the same way, across the three majors.
    • The Impact of Cooperative Video Games on Team Cohesion

      Anderson, Greg (2010-07-20)
      In today’s economy, productivity and efficiency require collaboration between employees. In order to improve collaboration the factors affecting teamwork must be examined to identify where changes can be made in order to increase performance. One factor contributing to teamwork is team cohesion and represents a process whereby members are joined by a common bond in the pursuit of a common objective. A popular social bonding activity sweeping the world is playing cooperative video games. The purpose of this study was to determine the effect of playing cooperative video games on team cohesion. Subjects (N=56) were randomly placed into 15 teams of three to four members. A modified Group Environment Questionnaire (GEQ) pretest was administered to determine the initial degree of cohesiveness between team members and to examine a wide cross-section of correlates and cohesiveness. Each team was randomly assigned to a specific intervention length of either one or three weeks with the one week groups playing for one hour and the three week groups playing for six hours. After the randomly assigned length of game play was completed, team members completed the modified GEQ posttest. The results of the posttest were compared with the pretest to determine the effect on the team’s cohesion. The data were analyzed using descriptive statistics (means and standard deviations) and a 2 x 2 MANCOVA was used to determine if playing collaborative video games affected the level of cohesion. A mixed design was used as post hoc analyses for each GEQ cohesive factor and indicated that levels of cohesion increased due to the intervention but was not dependent upon the length of the intervention. The results of this analysis indicated that video games can be used as a team building experience to improve cohesion regardless of how long the video game is played.
    • Application of Strategic Institutional-Information Technology Alignment Model in Four-Year Institutions of Higher Education

      Lach-Smith, Barbara (2010-09-22)
      This study examined an existing corporate model of business-information technology alignment for application in higher education and tested the findings by surveying executive and technology leaders in higher education. The purpose of this study was to gain a better understanding of the factors that impact alignment between institutional strategic planning and information technology strategy in higher education. The existing alignment model was examined in the context of mid-size four-year colleges and universities. This study used a combination of Delphi technique and a survey process. The sequence followed was to examine an existing theoretical model for its applicability to higher education by a Delphi expert panel, to pilot test the results of the Delphi in a survey of mid-size four-year institutions of higher education and to analyze the results. In the first phase, the Delphi method was used in two rounds to examine the Strategic Alignment Model (SAM) for application in higher education. An assembled panel of experts examined SAM, its components and questionnaire instrument, and reached a consensus after two rounds about the model’s applicability to higher education. The second phase of the study tested the Delphi panel’s findings by asking Chief Information Officers and Chief Executive Officers from four-year U.S. institutions of higher education to complete SAM’s instrument that was modified by the Delphi. The Delphi panel findings supported the use of the Strategic Alignment Model in higher education with some revisions of its terms to reflect the higher education environment more accurately. Several factors affecting institutional-IT alignment in higher education were identified. Factors associated with domain components of the SAM model as well as factors relating to bivariate linkages between the components of the model were revealed.
    • The Current Situation of Supply Chain Management and Technology Structure at Al-Hassan Industrial Estate in Jordan

      Alodeh, Mahmoud (2011-03-17)
      Introduction: countries all over the world have competed to develop their economies through different methods. One of the ways is enhancing Logistics and Supply Chain Management (LSCM). The Jordanian government is one of the governments that found out that if it needs to improve the Jordanian economy it has to improve the supply chain management (SCM) in almost every aspect of life. Problem: The current status of the use of information systems for LSCM at Al-Hassan Industrial Estate (AIE), and the current enterprises’ policies for LSCM were not known. Purpose: The study aimed to answer the following questions: What are the major challenges and developments with the use of information systems for LSCM? What is the actual level of satisfaction of current AIE enterprises’ policies regarding LSCM? Finally, what is the actual need of enterprises at AIE for the effective use of information systems for LSCM? Method: The questionnaire helped in gathering data from enterprises on issues related to challenges, benefits, and development on the use of information systems for LSCM in AIE. The researcher used all the 49 companies as the study population at Al-Hassan Industrial Estate in Jordan. The SPSS program helped in the analysis of the collected data. The descriptive analysis was used to represent the results. Conclusions: This study provides a first overview of the Jordanian companies regarding the LSCM. This study aimed to explore the state of logistics and supply chain management and the use of information systems to support LSCM at AIE. Current companies’ policies are focusing on suppliers more than customers. Also, the companies have to spend more effort to develop their LSCM planning by using techniques such as employee training. In addition, they are using the standard package systems more than customized systems. Also, most of the companies benefit more than average by using LSCM systems. Finally, the majority of these companies are not satisfied with the current policies.
    • Effects of Joint Preparation Angle of Single-vee Butt Welds on the Tensile Strength of ASTM A36 Carbon Steel

      McClure, Matthew (2011-07-20)
      Welding is a multi-faceted procedure of manufacturing and can occur at any point during the creation of a product. Quality issues in welding can have disastrous, or even deadly, consequences. The issue of weld preparation angle is one of several different elements that have a direct correlation on the quality of a welded joint. The purpose of this research centers on resultant tensile strength of a single-vee butt joint in carbon steel with various preparation angles. Preparation angles were machined on twenty-six pieces of ASTM A36 carbon steel in 5° increments in order to produce thirteen samples with included preparation angles ranging from 0° to 120°. Test samples were developed using an automated welding process that remained consistent for all of the welds. Each sample was plasma cut into ten coupons, which were machined to have a uniform cross section of the welded joint and surrounding parent material using a computer numerically controlled machining center. This yielded a total population of 130 coupons, which were tested to failure using a United Testing Systems stress/strain tensile tester. The empirical data were analyzed via the use of SPSS 18 statistical software. Initially, the level of population variance was assessed within groups and between groups by use of a one-way ANOVA test at the .05 alpha level. The result showed a statistically significant difference of the sample population. Secondly, a comparison of the data at various preparation angles to that of the industry standard angle of 60° was assessed using a Bonferroni multiple comparisons at the .05 alpha level, which resulted in one angle being statistically significant compared to the industry standard.
    • Effects of Globalization on the Gas Engine Manufacturing and Parts Industry in Indiana As Experienced By Those Working In This Sector

      Polastri, Patricia (2012-01-19)
      Globalization has often been perceived as the culprit in the decline of employment in several manufacturing industries in the United States. The purpose of this research was to investigate how globalization affected the gas engine manufacturing and parts industry in Indiana during the period of 1998 – 2008, in order to assess the perception of industry professionals as to the characteristics that could, or have, led to globalization through offshoring and outsourcing. Additionally factors for the employment decline experienced in this industry were identified and assessed. For this study an anonymous online survey was conducted targeting individuals directly associated with this industry and holding positions in the areas of engineering and management. The survey addressed the areas of technology, education, globalization/competition and employment. The survey results identified factors such as the influx of foreign goods, quality, workforce skill sets, and automation as competitive deficiencies present in this industry. These results are in contrast to the common perception that offshoring is the main factor for the dislocation of workers related to this sector. Further research in these areas could be conducted to ascertain the interrelated connections, as well as the level of their impact on these manufacturers.
    • Sustainable construction practices:contractor's perceptions of awareness and participation.

      Fee, Scott T (2012-05-16)
      The U.S Green Building Council's(USGBC)Leadership in Energy and Environmental Design(LEED)rating system is the current industry standard for sustainable building practices.This study employed an online survey instrument to collect data from contractor members of the Associated General Contractors of America(AGC).The instrument asked respondents to score their firm's awareness of LEED green building practices and the firm's participation in projects using these practices.According to the AGC,its leadership intends to work with USGBC to build the construction industry's awareness of and participation in LEED specifically and sustainable construction in general.By conducting a survey of 4232 contractor members of the AGC,this study has established current levels of contractor's awareness of LEED practices and their participation in projects that employ LEED methods.Correlation analysis was employed to calculate the degree of correlation between scores in the response categories of "Awareness" and "Participation".Means analysis addressed research questions regarding differences in the means of LEED awareness and LEED participation responses within selected demographic categories.Spearman's rho analysis produced results indicating correlation between awareness and participation scores.ANOVA and Tukey post-hoc analyses indicated significant differences in the mean responses for the demographic categories of:(a)type of firm,(b)annual dollar volume and (c)company size.

    • A STUDY OF THE MATERIAL INSPECTION RECORD AND QUALITY SYSTEMS: A CASE IN THE UNITED STATES DEPARTMENT OF THE NAVY

      Brown, Larry W. Jr. (Cunningham Memorial Library, Terre Haute, Indiana State University., 2017-12)
      Defective products and services are a part of every industry, sector, and organization. Minimization of those defects is essential for business success. The later those defects are found, the more they cost the business and consumer. This study investigated the impact having an accredited Quality Management System (QMS) had on the acceptance of delivered product. The study focused on the products delivered to the Naval Sea Systems Command (NAVSEA) and Naval Supply Systems Command (NAVSUP) organizations. This study investigated the statistical significance between the means of the groups within size and number of accreditation. The dependent variables were Material Inspection Record (MIR), units received, and units rejected, or products delivered to the NAVSEA and NAVSUP organizations. The study used the PDREP Metric Dashboard data for fiscal year 2012, quarter 1 through fiscal year 2016, quarter 2, resulting in more than 8,000 records analyzed and interpreted using a one-way ANOVA and General Linear Model. The results of the analysis indicated there were no significant differences between size or accreditation of organizations, when compared to the number of rejected units and Material Inspection Report (MIR) acceptance or rejection. The analysis did suggest there is statistical significance when size and accreditation are compared to MIR acceptance or rejection (F-Value 3.01, P-Value 0.006). Additional analysis was conducted for within group comparisons and small organizations were identified as having a statistically disproportionate percentage of units rejected (76.61 percent), when compared to the percentage of units received (55.24 percent). iv Within small organizations, organizations with one accreditation had the highest ratio of units rejected compared to units received (2.00 to 1) as a percentage of units received within small organizations. Further research was recommended to explore other factors that would improve risk assessment and mitigation within the Department of Defense (DoD).
    • DEVELOPMENT OF A QUALITY MANAGEMENT ASSESSMENT TOOL TO EVALUATE SOFTWARE USING SOFTWARE QUALITY MANAGEMENT BEST PRACTICES

      Erukulapati, Kishore (Cunningham Memorial library, Terre Haute,Indiana State University, 2017-12)
      Organizations are constantly in search of competitive advantages in today’s complex global marketplace through improvement of quality, better affordability, and quicker delivery of products and services. This is significantly true for software as a product and service. With other things being equal, the quality of software will impact consumers, organizations, and nations. The quality and efficiency of the process utilized to create and deploy software can result in cost and schedule overruns, cancelled projects, loss of revenue, loss of market share, and loss of consumer confidence. Hence, it behooves us to constantly explore quality management strategies to deliver high quality software quickly at an affordable price. This research identifies software quality management best practices derived from scholarly literature using bibliometric techniques in conjunction with literature review, synthesizes these best practices into an assessment tool for industrial practitioners, refines the assessment tool based on academic expert review, further refines the assessment tool based on a pilot test with industry experts, and undertakes industry expert validation. Key elements of this software quality assessment tool include issues dealing with people, organizational environment, process, and technology best practices. Additionally, weights were assigned to issues of people, organizational environment, process, and technology best practices based on their relative importance, to calculate an overall weighted score for organizations to evaluate where they stand with respect to their peers in pursuing the business of producing quality software. This research study indicates that people best practices carry 40% of overall weight, organizational best v practices carry 30% of overall weight, process best practices carry 15% of overall weight, and technology best practices carry 15% of overall weight. The assessment tool that is developed will be valuable to organizations that seek to take advantage of rapid innovations in pursuing higher software quality. These organizations can use the assessment tool for implementing best practices based on the latest cutting edge management strategies that can lead to improved software quality and other competitive advantages in the global marketplace. This research contributed to the current academic literature in software quality by presenting a quality assessment tool based on software quality management best practices, contributed to the body of knowledge on software quality management, and expanded the knowledgebase on quality management practices. This research also contributed to current professional practice by incorporating software quality management best practices into a quality management assessment tool to evaluate software.
    • KEY PERFORMANCE INDICATORS OF PART-TIME EMPLOYEES TEACHING ONLINE

      Alexander, Mark L. (Cunningham Memorial library, Terre Haute,Indiana State University, 2017-12)
      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.

    • OPERATIONALIZING HUMILITY: A MODEL OF SITUATIONAL HUMILITY FOR CHRISTIAN COLLEGE STUDENT LEADERS

      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.
    • WHAT IS THE INFLUENCE OF FORM-FOCUSED INSTRUCTION OF COPULA AND AUXILIARY (BE) ON ESL LEARNERS?

      Alraddadi, Abdulaziz Ibrahim (Cunningham Memorial library, Terre Haute,Indiana State University, 2017-12)
      This study explored the influence of form-focused instruction (FFI) in teaching English copula and auxiliary (be) to English as a second language (ESL) learners. Following the noticing hypothesis, FFI, and the basic principles of curriculum and instruction theory, this study investigates if ESL learners make omission, misuse, or misjudgment errors while acquiring English as a second language. Also, the study examined whether ESL learners show significant improvement in their knowledge of English copula and auxiliary (be) after receiving FFI. Previous copula and auxiliary (be) research (Jishvithaa, Tabitha, & Kalajahi, 2013; Muftah & Eng, 2011; Unlu & Hatipoglu, 2012) has shown that ESL learners commit omission and misuse errors. It was the aim of this study to investigate that ESL learners commit those errors and to add misjudgment errors to the investigation. Moreover, the study also aimed at examining the influence of FFI on the ESL learners’ knowledge of copula and auxiliary (be). Previous research on FFI influence (Ellis, 1984; Tomita & Spada, 2013; Valeo, 2013) has shown a positive influence of FFI on learning and acquiring grammatical structures. This study adds more findings by focusing on the influence of FFI on the ESL learners’ knowledge of the copula and auxiliary (be) in the present tense. This study was a quantitative quasi-experimental one. It utilized a control group and an experimental group. It followed a pretest-treatment-posttest, control-group design. Participants were 14 ESL learners (10 in experimental group, 4 in control group) who were in two existing groups at two ESL classes in a Midwestern university. The results reflect that participants made v omission, misuse, and misjudgment errors. The participants committed more misjudgment errors and less omission and misuse errors. All participants showed a significant change overtime in regard to making misjudgment errors. The outcomes highlight misjudgment errors as a potential type of errors that ESL learners may commit with copula and auxiliary (be). The experimental group outperformed the control group over time by significantly making less omission errors. When compared over time and between groups, participants’ scores on the grammatical judgment tasks have shown improvement suggesting a positive effect of FFI treatment on the participants’ knowledge of copula and auxiliary (be). Further research is needed to involve a larger participant population and more types of copula and auxiliary (be) errors.
    • 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.
    • A STUDY OF THE FACTORS INFLUENCING LAST MILE RESIDENTIAL FIXED BROADBAND PRICING IN KENTUCKY

      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.
    • DISTRIBUTED COMPUTING IN INTERNET OF THINGS (IoT) USING MOBILE AD HOC NETWORK (MANET): A SWARM INTELLIGENCE BASED APPROACH

      SELVADURAI, JOHN (Cunningham Memorial Library, Terre Haute, Indiana State University., 2017-12)
      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.
    • THE EFFECTIVENESS OF CONCURRENT DESIGN ON THE COST AND SCHEDULE PERFORMANCE OF DEFENSE WEAPONS SYSTEM ACQUISITIONS

      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.
    • 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.
    • 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.
    • An investigation of the early factors which influence women's career choices in physical science and technology

      Payne, Anneliese
      The composition of the workforce has begun to undergo a change. The U.S Department of Labor estimates that women, minorities and immigrants will constitute 80 percent of the additions to the labor force between 1987 and the year 2000 (Oakes, 1990). The National Science Foundation projects that the United States may have a shortfall of 40,000 scientists and over 250,000 engineers by the year 2006 (Argonne, 1990). Since women are among those who are significantly underrepresented among individuals preparing for a career in science, thirty women who are currently pursuing a successful career in physical science and technology were interviewed. This study determined participants perceptions of the factors that first influenced an early interest in physical science and technology. The investigation included perceptions regarding: 1) whether certain identifiable events or experiences influenced the decision to pursue science as a career and what those events and experiences were; 2) at what age these events occurred; 3) whether an adult(s) was influential and which adult(s) it was; and 4) identification of where these events and experiences occurred. The interview technique was selected as the best research method for collecting the qualitative and demographic data needed for this study. The results represent the participant’s recollections of out-of-school and in-school activities, family, friends and teacher support, self-image during the formative years, parents as the most important factor which influenced an interest in physical science, and major obstacles that had to be overcome by the participants in order to pursue successful careers in physical science and technology. Also included is participant’s advice to parents and teachers who want to encourage females to pursue a career in physical sciences and technology.
