The Effects Of Wheatgrass Length On Antioxidant Activity And Total Phenolic Content Inwheatgrass (Triticum Spp.), Yusuf Şavşatli Jan 2020

The Effects Of Wheatgrass Length On Antioxidant Activity And Total Phenolic Content Inwheatgrass (Triticum Spp.), Yusuf Şavşatli

Turkish Journal of Agriculture and Forestry

This study was carried out with the aim of determining the effects of wheatgrass lengths on antioxidant activity and total phenolic content of wheatgrass belonging to different cultivars (Triticum spp.) in laboratory conditions in 2017. When the wheat seedlings grown in plastic containers under soilless conditions reached three levels of wheatgrass length (5-6, 8-9, and 11-12 cm), the seedlings were cut from the root collar and dried in an oven. As a result of analysis of the dried material, it was found that the cut lengths of wheatgrass significantly (P < 0.01) affected antioxidant activity and total phenolic content of wheatgrass. Ten wheat cultivars belonging to Triticum monococcum L., T. durum L., and T. aestivum L. were used. Wheatgrass was cut at three lengths (5-6, 8-9, and 11-12 cm). It was found that the wheatgrass lengths had a significant (P < 0.01) effect on antioxidant and total phenolic content of wheatgrass. In addition, in terms of these traits, the most suitable wheatgrass length for cutting changed depending on the wheat species and also cultivars. The highest (P < 0.01) antioxidant activity and total phenolic content (TPC) were also determined at three wheatgrass lengths in cultivar Sarıbaşak. The average values obtained from Sarıbaşak wheatgrass were 31.0% for DPPH-free radical scavenging activity and 51.6 mg GAE-1 dry weight for TPC. The results of the analysis suggested that Sarıbaşak is the most promising cultivar in terms of both antioxidant activity and TPC in wheatgrass.

Inequality In The Social Mind: Social Comparison And Support For Redistribution, Meghan Condon, Amber Wichowsky Jan 2020

Inequality In The Social Mind: Social Comparison And Support For Redistribution, Meghan Condon, Amber Wichowsky

Political Science Faculty Research and Publications

Income inequality is fundamentally relational in nature, but research on the American public’s response to it tends to examine individuals in isolation, concluding that support for redistribution is unresponsive to inequality. We focus instead on perceptions of relative socioeconomic position, which we manipulate experimentally through imagined social interactions with high- or low-status others. We find that subjects who make social comparisons between themselves and someone who is socioeconomically advantaged perceive their own status as lower, assess their own socioeconomic status more accurately, and become more supportive of social welfare spending, even though we provide no factual information about the income …

In recent years, improving the quantitative methods used to assess the effect of college, and particular college experiences, on student outcomes has received increased attention (e.g., Mayhew et al., 2016). In How College Affects Students, Mayhew et al. (2016) highlighted the importance of issues of practical vs. statistical significance, self-selection into college (and by extension, self-selection into particular experiences), and direct and indirect effects, among other methodological challenges in identifying the relationships between college experiences and student learning and success. One particularly difficult challenge is identifying the conditional effects of experiences on student outcomes. Who benefits, or who does not, …


Exploring Cultural Logic In Becoming Teacher: A Collaborative Autoethnography On Transnational Teaching And Learning, Taeyeon Kim, Heather L. Reichmuth Jan 2020

Exploring Cultural Logic In Becoming Teacher: A Collaborative Autoethnography On Transnational Teaching And Learning, Taeyeon Kim, Heather L. Reichmuth

Department of Educational Administration: Faculty Publications

Departing from the view that learning is a linear progression, we argue that through the lens of cultural historical activity theory (CHAT) and cultural logic, teacher learning research can be advanced. Applying these two constructs to a collaborative autoethnography of two emerging scholars’ transnational teaching and learning experiences in the US and South Korea we argue that implicit and explicit norms in a culture influence the process of becoming teacher in the Korean context. Findings suggest that socio-cultural elements of implicit beliefs and norms outside of schools are linked to teacher learning inside schools, thereby suggesting that teacher learning at …
