There are many opportunities to use engineering skills to improve the conditions for mar-ginalized communities, but our current engineering education praxis does not instruct on how engineering can be a force for human development. In a time of great inequality and exploitation, the desire to work with the impoverished is prevalent, and it has been proposed to adjust the engineering curriculum to include a larger focus on human needs. This proposed curriculum philosophy is called humanitarian engineering. Professional engineers have played an important role in the modern history of power, wealth, economic development, war, and industrialization; they have also contributed to infrastructure, sanitation, and energy sources necessary to meet human need. Engineers are currently at an important point in time when they must look back on their history in order to be more clear about how to move forward. The changing role of the engineer in history puts into context the call for a more balanced, community-centred engineering curriculum. Qualitative, phenomenographic research was conducted in order to understand the need, opportunity, benefits, and limitations of a proposed humanitarian engineering curriculum. The potential role of the engineer in marginalized communities and details regarding what a humanitarian engineering program could look like were also investigated. Thirty-two semi-structured research interviews were conducted in Canada and Ghana in order to collect a pool of understanding before a phenomenographic analysis resulted in five distinct outcome spaces. The data suggests that an effective curriculum design will include teaching technical skills in conjunction with instructing about issues of social justice, social location, cultural awareness, root causes of marginalization, a broader understanding of technology, and unlearning many elements about the role of the engineer and the dominant economic/political ideology. Cross-cultural engineering development placements are a valuable pedagogical experience but risk benefiting the student disproportionately more than the receiving community. Local development placements offer different rewards and liabilities. To conclude, a major adjustment in engineering curriculum to address human development is appropriate and this new curriculum should include both local and international placements. However, the great force of altruism must be directed towards creating meaningful and lasting change. / Thesis (Ph.D, Civil Engineering) -- Queen's University, 2008-08-25 09:04:54.722

Product development is continually becoming more challenging as global competition requires more efficient design methods. The reuse of company knowledge, specifically the design rationale that occurs during projects is essential to success. This thesis presents a method for integrating engineering and communication tools for purposes of automating the capture of communication-based design rationale. The method is based on four basic principles: to integrate, to make data retrievable, to minimize user interaction, and to store as much DR as possible. The core method consists of two primary operations, the first being to capture the design rationale, and the second being to provide for effective retrieval. An implementation of this method that uses NX as the engineering tool and Skype VoIP software as the communication tool was created for the purpose of testing integration as a means of DR capture. The implementation was evaluated using four separate tests, which focus on efficiency of capture and retrieval, cost analysis, and user satisfaction. These results show that the tool provides improvement in each of the tested categories. From this testing I conclude that integrating communication and engineering tools is an excellent way to capture communication-based design rationale. The tool presented is more efficient than traditional methods in the test cases and provides a user-friendly solution to DR capture. This tool also has various other important applications, such as global collaboration and expectation management. It also provides an excellent framework for upcoming multi-user CAx tools.

Universities across the United States have integrated international experiences into their engineering students' education. International engineering programs provide learning and professional opportunities for participating faculty and students while aiding international partners in their own efforts. These programs are unique from traditional engineering courses and projects and generate outcomes desired for engineers entering the workforce including professional skills, critical thinking skills, and a strong understanding of their target audiences. While individual programs have explored the impacts of their programs on their students and their resulting project outcomes, there are significant gaps when considering the following: 1) how are programs structured, 2) what are the intended learning outcomes, 3) why do faculty participate in these programs, 4) how are relationships formed and maintained with international partners, and 5) what barriers exist that limit international engineering programs? To address these gaps, I interviewed 25 program faculty and 40 students. Through qualitative analysis of these interviews, I found that programs shared a common consideration for the program's focus on student learning or achieving international partner goals. Programs approached both structure and learning outcomes with either more emphasis on one or the other; balancing these two goals was a challenge for most programs. Faculty were motivated to participate in international engineering programs by their own intrinsic values, however, many felt limited when in traditional tenure track positions. Students tended to reflect more deeply and from a systems perspective the more exposure and time in a program. Students who engaged in either multiple programs or longer participation within a program tended to reflect their experiences contributed more to their current and future career plans. Partners were typically developed initially through personal relationships of the faculty members or through third-party organizations that specialize in international work. Maintaining relationships was highly varied between programs, but a common deficit among programs was the ability to evaluate project outcomes with partners in a numerical way. The examination of these questions about international engineering programs provides a foundation of knowledge for future programs to build on and for existing programs to compare their approaches. This is a critical step to implementing these types of programs in a more widespread and intentional way. / Doctor of Philosophy / Universities across the United States have added international experiences into their engineering students' education. International engineering programs provide learning and professional opportunities for participating faculty and students while aiding international partners in their own efforts. These programs are unique from traditional engineering courses and projects and help students learn professional skills, critical thinking skills, and a strong understanding of their target audiences to prepare them for jobs. While individual programs have explored the impacts of their programs on their students and their resulting project outcomes, we don't know the following: 1) how are programs structured, 2) what are the intended learning outcomes, 3) why do faculty participate in these programs, 4) how are relationships formed and maintained with international partners, and 5) what barriers exist that limit international engineering programs? To answer these questions, I interviewed 25 program faculty and 40 students. I transcribed and used qualitative coding to analyze the data from faculty and students. Through these interviews, I found that programs shared a common consideration for the program's focus on student learning or achieving international partner goals. Each primary focus leverages different aspects of program design, learning, and participation outcomes to achieve those goals. Faculty were motivated to participate in international engineering programs by their own personal and moral values, however many felt limited when they held traditional tenure track positions. Students tended to reflect more deeply and from a systems perspective the more exposure that they had to a program in terms of length. While participation one time led to valuable learning and reflected learning, those that engaged in either multiple programs or longer programs tended to consider more components of their experiences as it affected their current and future plans. Partners were typically developed initially through personal relationships of the faculty members or through third party organizations who specialize in international work. Maintaining relationships was highly varied between programs, but a common deficit among programs was the ability to evaluate project outcomes with partners in a numerical way. These answers help future programs to strategically build programs and helps existing programs compare their program to others.

Every manufactured product has an environmental impact, a social impact, and an economic impact. As engineers, we should do our best to understand how our design decisions influence these impacts (the three pillars of sustainability), and at the same time make decisions that collectively lead to maximum positive impacts, or minimum negative impacts on the economy, environment, and society. Many times, engineers show interest and want to design for all three pillars of sustainability but are often constrained to focus on the environmental and economic aspects, leaving out social sustainability due to lack of understanding and resources. In practice, this leaves the social dimension of sustainability out of sight and reach for many engineers. So to assist engineers to consider and improve the social impacts of their products, we have created two methods. The first method is focused on meeting customers' unmet needs through the use of collaborative products (a product created by temporarily combining physical components from two or more products to perform new tasks) and the second method is to be used throughout the product development process in order to increase the potential social impacts of the product being designed. It will assist engineers to become aware of social impact categories sometimes overlooked, especially when designing for global engineering. If engineers are able to focus on all three pillars of sustainability early in the design process, including social sustainability, they can add social impact indicators along with technical performance measurements during the product development process and design a product that better meets the requirements for environment, economic, and social sustainability. This is why it is important for engineers to know how to handle the complexity and uncertainty associated with design parameters when creating products for social impacts aimed at global development. In this dissertation, the two methods are outlined and explained. The demonstration of the first method showed that by using the method of collaborative product design to create a brick press, the task-per-cost ratio was improved by 30%. The demonstration of the second method showed that a redesign of the cup seal in the India Mark II/III hand pump system (a product used by approximately 10% of the world's population) could extend the service interval with 12% by replacing the cup seals. Lastly, conclusions related to improving social impacts when engineering for global development and suggestions for future research are outlined.

As engineering work becomes more globalized, it is important to prepare students to succeed in a global engineering workforce. Prior research has explored different factors important to the design of global programs generally, but less is known about the experiences and learning outcomes of engineering students while abroad. Because this population has historically been underrepresented in global programs, few research-based practices have been identified to support the intentional design of global experiences for engineering students. This dissertation seeks to provide such insights through three studies that address the following components of global engineering program design: 1) the assessment of Global Engineering Competency (GEC) through use of a series of scenarios based in the Chinese context; 2) the relationship between program destination and students’ experiences and reported learning outcomes; and 3) the experiences that engineering students identify as most significant during their time abroad. I used a combination of quantitative, qualitative, and mixed research methods to explore students’ learning and experiences in global engineering programs. The results of these studies revealed that engineering students have a wide variety of learning outcomes and experiences as a result of global programs, that great care should be exercised in choosing and interpreting assessment methods for global programs, and that the design of global engineering programs should be informed by characteristics of both the student participants and the program destination. Overall, the results of this dissertation highlight the importance of intentionality when designing global engineering programs to better prepare students for success in a global work environment. / Doctor of Philosophy / As engineering work becomes more globalized, it is important to prepare students to succeed in a global engineering workforce.

The 'flattening of the world', using Thomas Friedman's phraseology, is driving corporations to increasingly use collaborative engineering processes and global teams to operate on a global scale. Globalization of the traditional university engineering curriculum is necessary to help students prepare to work in a global environment. More scalable and economically sustainable program types are needed to enable the majority of students to obtain a globalized education. The purpose of this research was to determine how effectively a global team- and project-based computer aided engineering course provided learning opportunities that enabled students to develop elements of global competence in comparison to existing engineering study abroad programs. To accomplish this, research was necessary to identify, aggregate, and validate a comprehensive set of global competencies for engineering students. From a review of the literature and subsequent analysis, a set of twenty-three global competencies with an associated conceptual model was developed to group the competencies by contextual topics. Two surveys were then developed and distributed separately to academic and industry professionals, each of which groups largely confirmed that it was important for engineering students to develop these global competencies. Next, the traditional ME 471 class was restructured into a Global ME 471 course. A pilot program was conducted from which lessons learned were incorporated into the global course. Selected global competencies were included as new learning outcomes. Course learning materials, labs, and lectures were also updated to reflect the new course emphasis. A survey was developed to be sent to BYU engineering study abroad students and the Global ME 471 course during 2010. A statistical analysis of responses was used to identify significant differences between the response groups. In addition to the global competencies which were identified and validated, global collaborative project-based courses such as Global ME 471 were shown to be effective in enabling students to learn and develop selected global competencies. Study abroad programs and the Global ME 471 course were seen both to be complementary in their emphasis and supportive of global engineering. In addition, global collaborative project-based courses were shown to play an important part of a globalized engineering curriculum.
