Expanding responsibilities and shifting demands : an analysis of the effects of migration and employment on immigrant women's negotiating power in the household

Greer, Kerry 01 January 2006 (has links)
This study's objective was to examine the affect that migration and employment have on immigrant women's negotiating position within the household. Depth interviews were conducted with nine women who migrated to Portland, Oregon from Ethiopia or Eritrea. Women were encouraged to share a narrative history of their migration and employment experience. These interviews were analyzed to answer three primary questions: Who are immigrant women supporting through their participation in the paid labor market? How do women utilize gain access to employment opportunities and what strategies do women use once employed to meet competing demands on them at work and in the household? And finally, to what extent do women maintain control over their income and influence household decisions? This study found that women, particularly women who migrate prior to marriage, support natal households more than women who migrate after marriage. Women use social networks to find information about jobs, and once employed use an array of strategies to meet domestic demands. These strategies include joining households with other women to share household labor, finding employment opportunities that allow them to care for children while working, and having their mothers come to care for small children. Women who have recently married and have lived in the United States a short amount of time are most likely to express desire to maintain control over their income, while women who have lived in the United States for a longer time are more likely to pool their income with their husbands. Many women felt that they had an equal influence in household decisions as their husbands, but little evidence was provided that this was the case. Instead this study concludes that working outside of the home increases the perceived contribution that women make to the household leads to their empowerment and improves their negotiating position.

Street Level Food Networks: Understanding Ethnic Food Cart Supply Chains in Eastern Portland, OR

Novie, Alexander G. 25 November 2014 (has links)
Portland, OR, is the site of a unique urban food cart phenomenon that provides opportunities for small business ownership and access points for culturally specific food for the city's foreign-born and minority populations. Known as a "foodie haven," Portland also has an active sustainable food movement with engaged citizens and support from city and regional policies aimed at significantly increasing the consumption of local food. To date, there have been no in-depth studies on the sourcing habits of Portland food cart owners and whether or not these street-level actors are involved in the area's local alternative food movements (AFNs). The current understanding of the Portland food cart phenomenon is based on studies that have focused on carts and pods located in the central business district and "inner-ring" areas of the city. Areas beyond these locations (defined as Eastern Portland) are currently home to the majority of the city's growing foreign-born and minority populations. This thesis uses a situational analysis framework to explore the food supply practices of ethnic food cart owners operating in Eastern Portland cart pods. I investigate the feasibility of purchasing locally grown ingredients for use in ethnic cuisines and the degree to which cart owners incorporate the region's prevailing locavore ethics into their everyday culinary practices. Findings from this inquiry suggest that ethnic cart owners in Eastern Portland have a range of habitus, or personal dispositions and embodied knowledge, that is reflected in how they perceive the benefits of and barriers to "buying local" and the extent (if any) that they engage with AFNs in the Portland area. I assert that ethnic food cart owners in Eastern Portland are performing multiple community roles by providing access points for culturally specific cuisines for their particular ethnic groups, while also offering exotic experiences to other residents and tourists alike. I discuss variations within the food cart phenomenon itself by highlighting the differences in design, amenities, types of access, and neighborhood customer bases of cart pods located in Eastern Portland. Finally, I discuss future research directions for understanding the dynamics of food supply chains in small-scale, direct-to-vendor relationships and the implications for local and regional food sustainability policy goals.

Map-based Probabilistic Infinite Slope Analysis of the Stephens Creek Watershed, Portland, Oregon

Cole, Ryan Andrew 13 March 2013 (has links)
The Stephens Creek Watershed in southwest Portland, Oregon was chosen by the city as a pilot project for urban stream restoration efforts, and the infiltration of stormwater was identified as a potential restoration strategy. The Stephens Creek Watershed has historically been known to be unstable during high precipitation events (Burns, 1996), and the need to address the response of slope stability to anthropogenically-driven changing groundwater conditions is the focus of this study. Airborne light detection and ranging (LiDAR) and geotechnical data from the City of Portland were employed to create a high resolution (0.84 m2) physics-based probabilistic slope stability model for this watershed, using the map-based probabilistic infinite slope analysis program PISA-m (Haneberg, 2007). Best and worst case models were run using fully dry and fully saturated soil conditions, respectively. Model results indicate that 96.3% of the watershed area had a probability [less than or equal to] 0.25 that the slope factor of safety (FOS) was [less than or equal to] 1 for fully dry conditions, compared to 76.4% for fully saturated conditions. Areas that had a probability [greater than or equal to] 0.25 that the slope factor of safety (FOS) was [less than or equal to] 1 were found to occur mainly along cut/fill slopes as well as within the deeply incised canyons of Stephens Creek and its tributaries. An infiltration avoidance map was derived to define areas that appear to be unsuitable for infiltration. Based on these results, it is recommended that stormwater continues to be directed to existing sewer infrastructure and that the "storm water disconnect" restoration approach not be used by the city.

Ordinary Women/Extraordinary Lives: Oregon Women and Their Stories of Persistence, Grit and Grace

Leonetti, Shannon Moon 18 May 2015 (has links)
This thesis tells the stories of five Oregon women who transcended the customary roles of their era. Active during the waning years of the nineteenth century and the beginning of the twentieth century, each woman made a difference in the world around them. Their stories have either not been told or just given a passing glance. These tales are important because they inform us about our society on the cusp of the twentieth century. Hattie Crawford Redmond was the daughter of a freed slave who devoted herself to the fight for women's suffrage. Minnie Mossman Hill was the first woman steamboat pilot west of the Mississippi. Mary Francis Isom was a local librarian who went to France to deliver books to American soldiers. Ann and May Shogren were sisters who brought high fashion to Portland and defied the gender and social rules in both their business and personal lives. These women were not the only ones who accomplished extraordinary things during their lives. They are a tiny sample of Oregon women who pushed beyond discrimination, hardship and gender limits to earn their place in Oregon's history.

The Relationship Between School Integration and Student Attitude Toward Residential Racial Integration

Johnson, David Allen 01 January 1990 (has links)
This study examined factors related to the teaching effectiveness of adjunct faculty in higher education. Specifically, it explored the relationship between personality, as defined by the Five-Factor Model, occupation, and student ratings of teaching effectiveness. Results indicate that personality is correlated to an instructor's classroom behavior and education goals, which in turn are related to teaching effectiveness. In addition, instructors with occupations in social services and education had significantly higher mean teaching effectiveness scores than those from other occupations. Finally, there was an inverse relationship between age and teaching effectiveness in this study, and a positive relationship between teaching experience and teaching effectiveness. Although instructors may not be able to change their personality, they can modify their behavior and teaching practices to increase their effectiveness as educators.

Visions and Voices: An Arts-Based Qualitative Study Using Photovoice to Understand the Needs and Aspirations of Diverse Women Working in the Sex Industry

Capous Desyllas, Moshoula 01 January 2010 (has links)
The ways in which sex workers have been studied and represented historically, socio-politically and academically do not take into account their voices, subjective experiences and participation in the process. Women working in the sex industry are seldom heard and their needs are consistently defined and represented by others. This contributes to the stereotyping and stigmatization of sex workers, while academic research is consistently being done on sex workers instead of with them. This study uses the arts-based research method of photovoice with individuals working in the sex industry in Portland, Oregon to understand their needs and aspirations through their own artistic self-representation. Understanding sex workers’ needs from their own point of view provides the opportunity for collaborative knowledge creation of important issues in order to enhance social service design and delivery, and advocate for social change. Valuing sex workers’ aspirations supports the acknowledgement of individual strengths, skills, and visions. Drawing from techniques of interpretive phenomenological analysis methods, the themes that emerge to illustrate the participants’ needs and aspirations include: sustainability of the body; nourishment of the heart; fostering of the mind and soul; social justice and activism; dreams and desires; and self-empowerment and identity. The participants create meaning from their photographs through the use of self, performance, bodies, emotions, imagination, intellect, humor and story-telling. The role of intersectionality informs the sex workers’ diverse experiences and their unique ways of self-expression. The researcher uses collage as reflexivity to illustrate, contextualize and reflect her physical, emotional, and mental experiences throughout the study. The multiple art exhibits that ensue from this study allow for the artists’ visions and voices to travel to a broad audience beyond academia, in order to reach influential community advocates and challenge stigma and stereotypes. This arts-based study presents the richness and complexity of alternative forms of data, invites new levels of engagement that are both cognitive and emotional, and provides creative ways through which to explore and understand the experiences of sex workers.

Community level impacts associated with the invasion of English ivy (Hedera spp.) in Forest Park: a look at the impacts of ivy on community composition and soil moisture

Copp, Sara Rose 11 June 2014 (has links)
Invasive species degrade ecosystems by altering natural processes and decreasing the abundance and diversity of native flora. Communities with major fluctuations in resource supply allow invasive species to exploit limiting resources making the community prone to invasion. In the Pacific Northwest, urban forests characterized with limited light and seasonally limited soil moisture are being dominated by nonnative English ivy (Hedera spp). Three observational studies were conducted in the Southern end of Forest Park within the Balch Creek Subwatershed in Portland, Oregon in order to understand 1) how English ivy changes over three growing seasons, 2) how the native understory composition responds to English ivy, 3) if the dominance of English ivy reduces soil moisture to neighboring plants, 4) how English ivy and two co-occurring native herbs (Hydrophyllum tenuipes and Vancouveria hexandra) physiologically respond to seasonal changes in soil moisture. Percent cover of the understory community was collected in both 2010 and 2013 growing seasons in 54 plots in order to understand the change in cover over time. Community response and the relationship with soil moisture was analyzed using percent cover of the understory community and associated environmental variables including soil moisture collected in 128 plots during the 2013 field season. Finally, 15 plots with co-occurring Hedera spp, H. tenuipes and V. hexandra were sampled for stomatal conductance, leaf water potential, and associated environmental variables. Results show ivy cover increases on average 14% between 2010 and 2013 while native understory cover increased on average < 1%. Once ivy forms dense cover over 44% there is a reduction of native richness, diversity and herb cover while also an increase in available soil moisture and deciduous canopy cover. There were disparate impacts to different functional groups and between species. As functional group, the herbaceous community was the most impacted by ivy invasion. The shrubs and fern community had a variable response to ivy invasion. Many of the fern and shrub species least impacted by ivy also had associations with high soil moisture and deciduous canopy cover. Finally, data suggests that ivy does not take advantage of seasonally limiting soil moisture to invade the understory community. This study indicates that English ivy is both efficient at water use and may have the ability to obtain water from distant locations throughout the forest. Once established, ivy has the ability to alter the community composition. Ivy removal and habitat restoration are essential in order to maintain and enhance biodiversity in Forest Park.

Food Access Narratives in Southeast Portland, Oregon

Manser, Gwyneth Genevieve McKee 21 March 2017 (has links)
Since the late 1990's, "food deserts" have dominated the academic and policy literature on food access and food security. Food deserts are defined as areas that lack easy access to fresh, healthy, and affordable food, and are typically measured using Geographic Information Systems and spatial data sets. However, while food deserts may provide a useful measure for identifying food insecurity at a broad scale, they fail to account for individual definitions and perceptions of food access (Barnes et al. 2015; McEntee 2009). Furthermore, the food desert model assumes a lack of agency on the part of low-income populations (Alkon et al. 2013), and ignores other factors of food access, such as walkability, grocery store safety, customer service, and personal preference. In this research, I examine the food access perceptions of residents, non-profit employees, and business owners in the Lents neighborhood of Portland, Oregon. Although Lents is classified as a food desert, there is also an abundance of ethnic grocers and specialty markets within the neighborhood. These grocers reflect the neighborhood's racial and cultural diversity, and are often overlooked by the spatial datasets typically used to measure food access. The research that I conducted in Lents revealed a disconnect between how the residents I interviewed perceive their food environment, and how government, non-profits employees, and business owners within the neighborhood view local food access. The findings underscore the importance of factors other than physical proximity when measuring food access, and also show the importance of ethnic and specialty markets in the landscape. These findings support the assertion that binary measures of food access often fail to capture the complexities of individual perceptions of food access (Alkon et al. 2013).

Fuel model development and fire simulation analysis in the wildland-urban interface : the case of Forest Park, Portland, Oregon

Kuhn, David Malcolm 01 January 2005 (has links)
Forest Park, a 5,000 acre heavily-forested park within the city limits of Portland, Oregon was selected as the study area for performing a fire simulation analysis. A well-documented fire swept over a large area of the park in 1951, and provides both direct inputs, including the ignition point, and context for the present day fire simulations. The goal of the research was two fold. First, determine the difference between small area simulations using standard and custom surface fuel models. Second, determine if fire simulation can be an effective tool in assessing fire danger and behavior in a wildland-urban interface environment like Forest Park.
