Thesis advisor: Jacqueline V. Lerner / Young people identifying as Black, Latino/a/x, Hispanic, Asian, and other races and ethnicities that are minoritized and marginalized have constrained opportunities for positive development in the United States due to oppression grounded in white supremacy (NASEM, 2019). Importantly, youth of color engage in critical consciousness: interrogating and dismantling systems of oppression (Freire, 1970/2016). My aim was to illuminate the variation within youth of color in their development of critical consciousness, and to consider the implications for their overall development as viewed from a positive youth development perspective (Lerner et al., 2015). Associations between patterns of critical consciousness development and two variables measuring youths’ perceptions of their school context were examined. Using latent profile transition analysis, I explored variation among a sample of youth of color (n = 335) in cognitive, socioemotional, and behavioral processes of critical consciousness (Diemer et al., 2016; Watts et al., 2011) over a short longitudinal period. The mean age was fourteen at time 1 (which took place in 2016) and fifteen at time 2. Group-differential patterns in critical consciousness development were related to contribution—supporting the development of self and giving back to community; engagement in risk and problem behaviors; and emotional problems. Associations between patterns of critical consciousness development and (1) classroom discussions about social justice and (2) open classroom climate were estimated. Multiple patterns of engagement with critical consciousness were identified. Some youth shifted in their patterns of critical consciousness over time. Many participants reported a pattern of low engagement in multiple components of critical consciousness across both time points; higher classroom discussions about social justice were associated with a lower likelihood of youth following this pattern. These youth concurrently reported low contribution. Young people who sustained high levels across all dimensions of critical consciousness had high levels of emotional problems and risk and problem behaviors. Findings indicate broad involvement in critical consciousness can be associated with negative outcomes. Nevertheless, young people who were participating less in critical consciousness may struggle to promote positive development within themselves and their contexts through contribution. Implications for supporting the thriving of youth of color are discussed. / Thesis (PhD) — Boston College, 2021. / Submitted to: Boston College.

This study sought to determine whether a recently isolated slow-growing nonstarter lactic acid bacterium, Lactobacillus wasatchii sp. nov., could be implicated in late gassy defect in Cheddar cheese. I demonstrated that Lb. wasatchii grows readily in the laboratory under cheese-like stress conditions of 5% salt and pH 5.2, and has the potential to survive pasteurization. Lactobacillus wasatchii can co-utilize ribose and galactose to maximize its growth. Due to being an obligatory heterofermentative, Lb. wasatchii produces CO2 whenever it ferments a hexose such as galactose. A second investigation extended these findings by examining the growth and gas forming characteristics of Lb. wasatchii in Cheddar cheese. The optimum growth of Lb. wasatchii and highest levels of gas production were observed in cheese supplemented with ribose plus galactose, and stored at 12°C rather than 6°C. Lactobacillus wasatchii also grew readily and produced gas in Cheddar cheese even without added ribose and galactose, which corresponds with the ability of Lb. wasatchii to grow on starter cell lysate. A challenge still remains of how to easily enumerate Lb. wasatchii in cheese with a higher background population of other nonstarter lactic acid bacteria. The third set of experiments explored the consequences on growth and gas production of Lb. wasatchii in Cheddar cheese made with Streptococcus thermophilus. Using St. thermophilus in cheesemaking results in galactose accumulation, which Lb. wasatchii then can utilize for growth, causing release of CO2 with the end result of having blown Cheddar cheese. Results showed Lb. wasatchii or similar nonstarter lactic acid bacteria are likely to be particularly problematic in cheesemaking involving starter or adventitious St. thermophilus. From these observations, it was concluded that Lb. wasatchii is a contributor to late gassy defect in Cheddar cheese and may be widely present as part of the nonstarter lactic bacteria population but has been undetected up until now. The late gassy defect is more pronounced at temperatures used for accelerated ripening of cheese and when there are substantial residual levels of galactose in the cheese. Thus, researchers and cheese manufacturers now must consider slow-growing obligatory heterofermentative nonstarter lactic acid bacteria when dealing with late gassy defect in cheese.

This research provides a comprehensive picture of the economic status of the U.S. catfish industry through investigating several critical economic aspects such as technological progress, functional production relationships in intensive systems, regulatory costs, and economic contribution of the industry. The use of primary data is a unique aspect of this work reflecting the economic realities of catfish farms. Primary data collected through extensive in-person farm surveys covered over two-thirds of the catfish production areas in the U.S. The results of the study provided evidence of intensification in the U.S. catfish industry through increased adoption of two relatively new alternative production systems viz; intensively aerated ponds (6,315 ha) and split ponds (1,176 ha). The use of complementary technologies such as hybrid catfish on 53% of the catfish producing area and increased fixed-paddlewheel aeration rate of over 7.8 kW/ha also provided proof of technological progress on U.S. catfish farms. This study also identified critical factors contributing to productivity in increasingly adopted alternative production systems through two distinct production function models. Feed fed, as well as stocking biomass were found to be significant variables in both production functions. Results indicated further room for improvement in the use of inputs to increase production, especially in feed management. Along with identifying the nuances in the catfish industry, the study quantified regulatory costs on U.S. catfish farms at $45 million. Although faced with several hardships on the production front, the U.S. catfish industry contributes over $1.9 billion to the regional economy, supports more than 9,100 jobs, and generates over $78 million in tax revenues. The findings of the study serve a multitude of stakeholders including aquaculture farmers, researchers, Extension specialists, and policymakers who work towards improving the economic sustainability of the catfish industry as well as the U.S. aquaculture industry.

This dissertation consists of three studies related to accounting disclosure at the interface of the organization and society. The first study investigates the overlapping perspectives of legitimacy theory, institutional theory, resource dependence theory, and stakeholder theory and integrates these theories into a more cohesive meta-theory of the organization-society interface. The second study examines whether a corporation's charitable contributions represent a corporate social performance strategy or a legitimation strategy. More specifically, study two investigates, from two competing perspectives, how corporate executives rationalize their philanthropic actions. The third study analyzes the relationship between the current tax laws and the fulfillment of corporate foundations' social functions. Taken together, these three studies build upon prior theoretical and empirical work to advance social and environmental accounting research.

The growth of the mutual fund industry and the accompanying competition among intermediaries should lead to progressively lower costs to shareholders, based on economic theory. This dissertation is comprised of three studies which examine shareholder costs among mutual funds to test this theory. In each study the expense ratios of mutual funds are examined, while one study also includes an examination of commission structures. In Essay 1, the effect of participation in a supermarket No Transaction Fee program on a fund’s expense ratio is examined. In addition, the change in characteristics of these participants during a difficult market period is studied. Essay 1 finds that NTF participation leads to higher initial expense ratios but that continued participation depends on the program’s ability to pay for itself. In Essay 2, market segmentation within the fund industry is examined for this same time period. Essay 2 finds increased market segmentation over a five year period and finds evidence of competitive pricing only among certain segments. Retail investors who invest in no-load funds appear to benefit from competitive pricing more than those who pay commissions. There is evidence of cost shifting during this time period, as funds lower expense ratios but increase commissions. In Essay 3, expense ratios of common funds within state-sponsored defined contribution plans are examined. Essay 3 finds evidence of market segmentation among the various states. Plan size may have some effect on the setting of expense ratios, but the effect does not appear to be economically significant. Number of participants has no significant effect on the expense ratio. State population displays some significance, such that funds actually charge more for larger states. Wealth of the state, on the other hand, may result in lower expense ratios. Overall, competitive pricing within the mutual fund industry is limited to certain market segments and may be dependent on the channel of distribution.
