How might computer scientists work with communities in facilitating meaningful social change? In this project, we make a case for an approach that builds upon what the individuals and community already have---their assets---rather than emphasizing "user's needs" as typically postulated by human-centered design. We present details of our four-year-long assets-based engagement with an anti-trafficking organization in Nepal and the sex trafficking survivors supported by the organization. We explored the potential role that socio-technical systems and technology designers can play in assisting the survivors to build on their existing assets towards their vision of "dignified reintegration". The research involves three fieldwork and a remote study, each one leveraging carefully tailored socio-technical systems to investigate a design proposition. We present an operationalizable definition of assets and a framework of action to leverage assets in realizing change at an individual and institutional level. We describe the conditions that influenced the possibilities for our interventions and the factors that guided the design of the socio-technical systems. We further highlight how we adapted our methods to the local resources and practices in order to foster a space that promoted comfort and control to the study participants. The detailed account of our approach aims to provide a justification for undertaking slow, incremental steps with the community. / Doctor of Philosophy / Human trafficking survivors face a myriad of challenges in their reintegration journey. Working with an anti-trafficking organization in Nepal, I explored the potential role that technology and technology designers can play in assisting the survivors in their reintegration journey. The research involved three forays into fieldwork and a remote study, each one leveraging carefully tailored activities to investigate the possibilities for the survivors to be in a position of power once they leave the shelter home. The activities included technology such as a specifically tailored web application contextualized around the survivors' existing strengths but also involved non-digital components such as collectively envisioning broader possibilities and alternative futures and discussing ways in which the survivors could engage with local actors to mitigate societal problems they had seen near their homes. In all these activities, I adapted local practices and materials to promote a safe space for the survivors to participate from within their realm of comfort. This dissertation illuminates a potential pathway to engage in long-term community-based research with vulnerable populations. In particular, it makes a case for an approach that builds upon what the individuals and community already have, that is, their assets. The work illuminates ways to identify and build upon assets to support the survivors. Using the work, we make a case for undertaking slow, incremental steps as part of assets-based engagement with communities. The work emphasizes the need for technology developers to understand their responsibilities and carefully contemplate what elements of a situation or design allow ethical intervention. Finally, the work emphasizes the need for developers to be cognizant of how design of technology is tied up with the larger, multi-level system in which technology use is embedded.

One of the historically marginalized populations in the United States (US) is the Black population. This marginalization extends into higher education, where Black students are underrepresented and continue to experience challenges, especially at Predominantly White Institutions (PWI) and in science, technology, engineering, and mathematics (STEM) programs. However, the current constitution of the Black population, including Black students in the US, is inherently culturally and ethnically diverse. The Black student population includes domestic US students and various groups of foreign-born students such as Black Sub-Saharan African (BSSA) students whose educational trajectories, outcomes, and experiences are unique based on their cultural orientations. Given the within-group differences in this population, prior research has demonstrated the need to disaggregate the experiences in research among different groups for precise research outcomes. This dissertation contributes to that effort by explicitly focusing on the lived experiences of BSSA graduate students pursuing STEM degrees at a PWI through two studies from an assets-based approach: 1) the meaning BSSA graduate students in STEM make of their lived experience with the campus climate at a PWI, using community cultural wealth as a conceptual framework; and 2) the role of family and other funds of knowledge in the educational trajectories and persistence of BSSA doctoral students pursuing STEM degrees at a PWI. I used different qualitative methodologies across both studies, including a blended case study with tenets of participatory action research in the first study in the first study and narrative analysis in the second. The results of these studies revealed that BSSA graduate students in STEM and at PWIs possessed a variety of assets that enable them to resist challenges and persist in their education. Second, the educational environments were not holistically supportive of students. Finally, there was a lack of cultural awareness and validation of students' assets and ways of knowing. The results offered implications for the BSSA graduate students in STEM in the US, scholars, practitioners at PWIs and in STEM departments who work with them, especially in creating inclusive and supportive academic environments. / Doctor of Philosophy / One of the underrepresented populations in the United States (US) is the Black population. The underrepresentation of the Black population extends into universities and colleges. Black students are underrepresented and continue to experience challenges, especially at White populated institutions (PWIs) and in science, technology, engineering, and mathematics (STEM) programs. However, the current body of the Black population, including Black students in the US, is made of many internal groups with different cultures and ethnicities. The Black student population includes domestic students from the US and other groups with international backgrounds who migrate to the US, such as Black students from Sub-Saharan Africa (BSSA), whose educational paths, performances, and experiences are different based on their cultural background. Given the internal group differences in this population, prior research has advanced the need to separately engage with the experiences among the different groups for specific research results and services for each group. This dissertation contributes to that effort by only focusing on the lived experiences of BSSA graduate students pursuing STEM degrees at a PWI through two studies on BSSA students' assets: 1) the meaning BSSA graduate students in STEM make of their lived experience with the campus climate at a PWI, using community cultural wealth as a conceptual approach; and 2) the role of family and other wealth of knowledge in the educational journeys and success of BSSA doctoral students pursuing STEM degrees at a PWI. I used different qualitative methodologies across both studies, including a blended case study with tenets of participatory action research in the first study and narrative analysis in the second. The results of these studies showed that BSSA graduate students in STEM and at PWIs possessed a variety of assets that enable them to resist challenges and persist in their education. Second, the educational environments were not entirely supportive of students. Finally, there was a lack of cultural awareness and support of students' assets and ways of learning. The results offered implications for the BSSA graduate students in STEM in the US, educators, administrators, and researchers at PWIs and in STEM departments who work with them, especially in creating inclusive and supportive academic environments.

The work described herein is situated in a larger study investigating regional food systems as a method for improving food access for vulnerable communities. This research is part of the United States Department of Agriculture's Agriculture and Food Research Initiative project titled Enhancing Food Security in the Northeast for Underserved Populations (EFSNE). This work is ongoing and currently in year five of five. One of the primary objectives in year five is to facilitate the development of Learning Communities in each of the eight communities participating in the study. To do so, the research team planned to develop tools and strategies for facilitation. The team identified a need to match strategies to the specific situation of each community. Thus, a tool was identified that might be useful in assessing the needs and readiness of the communities with respect to their access to healthy food sources. This research simultaneously evaluated the usefulness of the tool while assessing community readiness in six of the eight project communities. The tool used in this study, was a community level behavioral change model, the Community Readiness Model (CRM). The model was originally developed by the Tri-Ethnic Center in Colorado. We followed the CRM protocol for identifying participants. Twenty-four individuals from six locations involved in the EFSNE study participated in the interview process. The interviews were conducted using the semi-structured interview guide provided in the CRM protocol. We amended the guide by tailoring questions to address food access and ensuring questions were asked at the five levels of influence found in the Socio-Ecological Model. The final guide contained 40 questions; 18 were required by the protocol to score each community. Interviews were conducted by telephone by one researcher, transcribed, and then scored by two researchers according to the CRM protocol. The mean overall readiness score for the six communities assessed was 4.9 (SD 1.0). This score is firmly rooted in the pre-planning stage of readiness. Scores ranged from 3.7 to 6.2 on the 9-point scale. The CRM scoring protocol coupled with the overall readiness scores indicated that the three urban communities scored higher (mean 5.7, SD 0.6) than the three rural communities (mean 4.1, SD 0.7). While we found a utility to having scores on a continuum to quickly assess the communities of study, we found the qualitative data obtained from the interview process imperative to understanding the scores and the communities. We concluded that with a few amendments, the Community Readiness Model is a useful methodology to understand food access at the community level. Revealing the stages of readiness for food access change in the study communities contributed to our understanding of what types of programs exist for food access, what the communities' attitudes and feelings are around food access and guided strategy development for moving readiness for change forward. This lens also revealed that there is a need for education on existing and development of new food access policies. Furthermore, this work contributes to the practice of assessing community food security while simultaneously contributing to the development of parameters for community food security theory in food systems scholarship.
