Ethnic Differences in Iron Absorption and Its Relevance to Personalized Nutrition
Kimberly O’Brien 한국식품영양과학회 2021 한국식품영양과학회 학술대회발표집 Vol.2021 No.10
An individual’s genetic background may influence their biological responses to nutrients and their risk of subsequent adverse health outcomes that are linked to nutritional status. Identifying genes that are associated with nutrient utilization has great potential to improve human health and personalize nutritional intakes. Personalized nutrition approaches are highly relevant to iron homeostasis as both iron deficiency and excess impact risk of chronic disease and adverse health outcomes. Large screening studies have evaluated risk of elevated body iron stores as a function of ancestry and have found that individuals of Asian, particularly East Asian ancestry have the highest risk of elevated body iron stores. This finding is surprising given that the most common genetic mutations associated with iron overload (C282Y and H63D) are nearly absent among Asian individuals. Individuals of East Asian ancestry may also develop iron overload-related diseases such as diabetes at a lower body mass index than typically observed among other ancestry groups. Iron balance is controlled at the level of the enterocyte as humans have no regulatable means of excreting excess iron once absorbed into the body. We recently determined that Asian females absorb significantly more non-heme iron than White females even when controlling for body iron stores. Characterizing ethnic differences in iron absorption and identifying variations in genes that are associated with iron absorption may help target iron supplementation to individuals that will benefit most from these practices and optimize dietary iron intake recommendations. This is particularly important for iron given that prophylactic iron supplementation is often recommended to large subsets of the population during vulnerable life stages. One such example is universal prenatal iron supplementation. While this practice is beneficial in preventing maternal anemia in iron deficient women it may place those with certain genotypes at increased risk of excess body iron stores at maturity.

Stormwater runoff contains pollutants such as total suspended solids (TSS), nutrients and heavy metals that can cause harmful effects to the environment. Infiltration trenches (IT) are low impact development (LID) facilities that treat and reduce the volume of stormwater runoff through filtration, sorption processes and soil microbial activities. This study assessed the performance of an IT in treating nitrogen and phosphorus in stormwater runoff and to determine the characteristics and patterns of nutrient transport in an urban catchment area. Water samples from 46 monitored events from May 2009 to September 2019 were analyzed using standard methods for the examination of water and wastewater treatment. Primary hydrologic data were obtained from the Korea Meteorological Administration. The concentrations of total nitrogen (TN) and total phosphorus (TP) on stormwater runoff ranged from 1.7 to 21.2 mg/L and 0.16 to 6.6 mg/L, respectively. Organic forms of nutrients were dominant in urban stormwater runoff and constituted to 61% and 90% of the TN and TP forms, respectively. Greater rainfall intensities resulted to a decreased TN and TP removal efficiency. For a rainfall intensity of 11mm/hr, the recorded removal efficiency for TN and TP only amounted to 34% and 55%, respectively. Low rainfall intensities (<1mm/hr) resulted to 100% removal efficiency. Increasing rainfall depth and intensity resulted to a lower pollutant removal due to the increase in hydraulic loading rate. Filtration, adsorption and sedimentation mechanisms incorporated in the design of IT were found to be the main factors that affected the removal of nutrients within IT. Generally, the IT was capable of reducing nutrient concentrations in urban stormwater runoff. Moreover, hydraulic and hydrologic can greatly influence the performance of IT.

My paper performs a deconstructive reading of Canadian writer Isabella Valancy Crawford`s major work - her long poem, Malcolm`s Katie: A Love Story (1884). My reading, informed both by and against much of the critical reception of the work to date, understands Malcolm`s Katie as a hermeneutic exercise not simply in nineteenth-century gender-inscribed power relations but in the in/communicability of these using the love story as a dissident narrative strategy. Through a sustained reading against the grain, I argue that Malcolm`s Katie ``doubles its doubled discourse`` by at once participating in and against both patriarchal and feminist ideologies about women`s place in Crawford`s time. I read the text as Katie`s bildungsroman both through and as a metacritical engagement with the im/possibilities of inscribing women`s agency, choice, subjectivity in text, indeed, as story about women`s representation per se: to manipulate a figure from the poem itself, as speech [run] thus two different ways.
Strategic Responses to Chinese Election Interference in Taiwan’s Presidential Elections
Kimberly L. Wilson 경남대학교 극동문제연구소 2022 ASIAN PERSPECTIVE Vol.46 No.2
Scholars have found that election interference by a foreign power can increase political partisanship in a targeted state and can be an effective tool for throwing weight behind a candidate. We know less about how domestic political actors respond to election interference and how this affects the intervener’s strategies over time. Since Taiwan held its first direct presidential election in 1996, China has used numerous tactics to influence Taiwan’s elections. Taiwan’s political parties have adapted to China’s interference, with targeted candidates campaigning on election interference, and non-targeted candidates seeking to play a mediating role with Beijing. In response, China’s tactics have shifted: the broad threats of earlier elections have been replaced with narrowly targeted efforts to mobilize Beijing-friendly segments of Taiwan’s population.

Recent fashion trends using African prints are combined with a desire to provide outreach to artisans in Ghana, West Africa, leading to an investigation of mainstream consumer groups in the United States. The purpose of this research was to identify US consumer segments based on aesthetic preferences, purchase intentions and socially responsible behavior (willingness to support artisans) with regard to products made from Ghanaian fabrics. This research identifi ed ethnic apparel consumer segments based on consumer characteristics. First, Cultural Creatives, a psychographic scale, compared consumers regarding aesthetics/benefi ts of ethnic apparel and consumers’ willingness to support Ghanaian artisans. Next, clusters were compared according to demographics: age, ethnicity and education. Lastly, clusters were compared by purchase intention (of apparel and accessories), aesthetic preferences for fabrics (ie print size, as garment trim, as home furnishings) and social comfort (ie comfort wearing among others). By using multi-step cluster analysis, this study categorized respondents (N = 577) into three distinct segments: Artisan Shoppers, Holistic Shoppers and Ethnic Stylists. Based on the results, limitations and further research are discussed.
