Effect of Blood Pressure on the Retinal Vasculature in a Multi-Ethnic Asian Population Hypertension Research (2009) 32, 975–982 & 2009 The Japanese Society of Hypertension All rights reserved 0916-9636/09 $32.00 www.nature.com/hr ORIGINAL ARTICLE Effect of blood pressure on the retinal vasculature in a multi-ethnic Asian population V Swetha E Jeganathan1,2, Charumathi Sabanayagam2,3, E Shyong Tai4, Jeannette Lee3, Cong Sun1, Ryo Kawasaki1, Sangeetha Nagarajan2, Maisie Ho Huey-Shi2, Mya Sandar2 and Tien Yin Wong1,2 Blood pressure has a significant effect on retinal arterioles. There are few data on whether this effect varies by race/ethnicity. We examined the relationship of blood pressure and retinal vascular caliber in a multi-ethnic Asian population. The study is population-based and cross sectional in design. A total of 3749 Chinese, Malay and Indian participants aged X24 years residing in Singapore were included in the study. Retinal vascular caliber was measured using a computer program from digital retinal photographs. The associations of retinal vascular caliber with blood pressure and hypertension in each racial/ethnic group were analyzed. The main outcome measures are retinal arteriolar caliber and venular caliber. The results show that retinal arterioles were narrower in persons with uncontrolled/untreated hypertension (140.0 lm) as compared with persons with controlled hypertension (142.1 lm, P¼0.0001) and those with no hypertension (146.0 lm, Po0.0001). On controlling for age, gender, body mass index, lipids and smoking, each 10 mm Hg increase in mean arterial blood pressure was associated with a 3.1 lm decrease in arteriolar caliber (Po0.0001), with a similar magnitude seen in all three racial/ethnic groups: 3.1 lmin Chinese, 2.8 lm in Malays and 3.2 lm in Indians (Po0.0001 for all). Each 10 mm Hg increase in mean arterial blood pressure was associated with a 1.8 lm increase in venular caliber (Po0.0001); furthermore, the magnitude of this effect was similar across the three racial/ethnic groups. The effect of blood pressure on the retinal vasculature was similar across three major racial/ethnic groups in Asia.

Breen* School of Social and Political Science, University of Melbourne, Australia *Corresponding author. Email: [email protected] (Received 7 May 2020; revised 15 September 2020; accepted 22 September 2020) Abstract How do ethnically divided countries create inclusive and stable democratic institutions? Why do some kinds of federalism fail while others evolve? Scholars looking for answers to these kinds of questions have tended to focus on the West. Yet there are important les- sons arising from the substantial democratic and federal reforms that have taken place in Asia over the last few decades. These reforms signal a new model of federal democracy in Asia, comprising multilevel ethnoterritorial federalism, mixed-majoritarianism and a party system that includes both ethnic and multi-ethnic parties. This model has emerged , subject to the Cambridge Core terms of use, available at as a response to ethnic conflict and secession risks and reflects the high diversity of clus- tered communities and cross-cutting cleavages. Despite its overarching majoritarianism, the federal model has led to highly fragmented party systems and coalition governments, with positive implications for democratic stability. Together, these features go some way towards blending otherwise conflicting consociational and centripetal paradigms. 14 Mar 2021 at 01:37:17 , on Keywords: federalism; political parties; electoral systems; Asia; ethnic politics; consociationalism How do ethnically divided countries balance demands for autonomy with objec- 194.193.48.186 tives of stability and national unity?

    Disfranchised under the name of Zhonghua Minzu Wenjun Zeng Innovative Research in Conflict Analysis NYU IR MA Program Fall 2015 Disfranchised under the name of Zhonghua Minzu 2 Wenjun Zeng New York University Introduction: The origin and development of Zhonghua Minzu (Chinese Nation) China is a country with fifty-six ethnicities with Han being the vast majority. In China, many minorities own their own distinctive history and culture.1 Yet, these 56 ethnicities are usually simplified under the title of Zhonghua Minzu (Chinese national) by the government and Han people under political, social, and cultural realm. Under such identity, all Chinese nationals share the same ethnic origin of being the decedents of Yan, and Huang Emperor, two mythical figures from the ancient Chinese folklore.2 Zhonghua Minzu was created by a Chinese philosopher and revolutionary for articulating the anti-Manchurian identity during the late Qing Dynasty.3 It then remained until the establishment of the People’s Republic of China (PRC), by the Chinese Communist Party (CCP), as a political rhetoric to represent a unified Chinese identity. Minorities in China today assimilated their culture into Han Chinese on different degrees, including their languages, daily attires, social values, and religions. Chinese nation and Han ethnicity are interchangeable under many circumstances. However, even decades after CCP’s governing, Uyghurs, one of the Turkic Sunni Muslim minorities, remains distinct from the mainstream Chinese identity. The province they concentrated in, Xinjiang Uyghur Autonomous Region (XUAR), located in the western periphery of the country as showed in the Map 1. As its Chinese name “Xinjiang”—the “new territory”–implies, Xinjiang only became part of the Chinese administration in Qing Dynasty in 1 Over 90% of the Chinese population is Han.

  • Toward a Political Conception of Minority Rights: Reconciling Sovereignty, Human Rights and Minority Claims
    TOWARD A POLITICAL CONCEPTION OF MINORITY RIGHTS: RECONCILING SOVEREIGNTY, HUMAN RIGHTS AND MINORITY CLAIMS by Omid Mousavi Hejazi A thesis submitted to the Department of Philosophy In conformity with the requirements for the degree of Doctor of Philosophy Queen’s University Kingston, Ontario, Canada (November, 2016) Copyright ©Omid Mousavi Hejazi, 2016 Abstract The question that I will explore in this research dissertation is whether one can defend the rights of homeland minorities as a progressive extension of the existing norms of human rights. This question calls for several deeper inquiries about the nature, the function and the underlying justifications for both human rights and minority rights. In particular, this research project will examine the following issues: on what normative grounds the available norms of human rights and minority rights are justified; if there is any methodic way to use the normative logic of human rights to support substantial forms of minority claims, such as the right to self- determination; whether human rights can take the form of group rights; and finally, whether there is any non-sectarian basis for justifying the minority norms, which can be acceptable from both liberal and non-liberal perspectives. This research project has some implications for both theories of minority rights and human rights. On the one hand, the research employs the topic of minority rights to shed light on deficiencies of the existing political theories of human rights. On the other hand, it uses the political theory to shed light on how existing theories of minority rights could be improved and amended. The inquiry will ultimately clarify how to judge the merit of the claim that minority rights are or should be a part of human rights norms.

  • Status Change Model of Interethnic Riots
    societies Article Status Change Model of Interethnic Riots Sandra Marker School of Behavioral Sciences, Black Hills State University, Spearfish, SD 57783, USA; [email protected]; Tel.: +1-605-642-6239 Received: 12 September 2018; Accepted: 5 November 2018; Published: 8 November 2018 Abstract: The status change riot model opens up a new avenue of riot explanation. One that takes into consideration ethnic group relations and factors of group status and honor—i.e., dignity. The riot model asserts that the potential for a riot arises when new and old concepts about group statuses, and as such, ideas about appropriate intergroup behaviors, give rise to disputative intergroup interactions. The model affirms that a trigger event either by itself or in accumulation with other events drives actors to a dignity threshold that prompts them to riot. The model further relates that, once started, a riot will follow a general riot pattern that ends in either a status resolution or an increased strain in ethnic group relations. Keywords: interethnic riot; status; honor; social structure; intergroup relations 1. Introduction A global examination of ethnic group relations makes it clear that violence in the form of interethnic riots punctuates, and, at times, engulfs countries from around the world [1–3]. Notwithstanding the global prevalence of these events, no causal factor has been found that is more than moderately significant and no general process has been established that expresses observed riot behaviors [1,4]. The empirical inadequacy of riot theory may reside in the restricted narrative that is used to explain ethnic riots. Social scientist Steve Reicher [5] (p.

    APRIL 2019 260 THE SINIFICATION OF CHINA HOW THE MINORITIES ARE BEING MERGED INTO ONE NATION Jyrki Kallio APRIL 2019 260 THE SINIFICATION OF CHINA HOW THE MINORITIES ARE BEING MERGED INTO ONE NATION • The long-term aim of the Communist Party is to make China unified, and the most recent tool for this is the creation a Chinese nation. This term was included in the Constitution last year, which contradicts the definition of China as a multi-national state. • Unifying China includes promoting a Chinese identity through history and culture. The current borders and ethnic composition of China are presented as the results of natural processes. History is written from the viewpoint of the Han Chinese and their relations with the border regions. Culture is discussed in a similar Han-centric manner. • The Party has set “Chinese values” against “universal values” and religions. It demands religions to be Sinified in order to alleviate any risks they might pose to national unity. • Most concretely, the creation of a Chinese nation is affecting the people in Xinjiang. This has given rise to concerns in other countries. The Sinification of minority nationalities may potentially become a new stumbling block in China’s relations with Western states.

  • An Analysis of South Asian American Gendered Ethnicity Formation in Visual Media Portrayals
    Pardes vs. Swades: an Analysis of South Asian American Gendered Ethnicity Formation in Visual Media Portrayals Honors Research Thesis Presented in Partial Fulfillment of the Requirements for graduation with Honors Research Distinction in Comparative Ethnic and American Studies in the Undergraduate Colleges of The Ohio State University By Andrew Philip and Tanya Srivastava The Ohio State University May 2014 Project Advisor: Professor Binaya Subedi, Department of Teaching & Learning 2 ABSTRACT: As the number of South Asian Americans in the United States grows, so does their presence in mainstream American media, their production of alternative sources of Asian American film, and their cachet to develop Indian film industry (Bollywood) abroad. All three sources of media employ and depict South Asian Americans in various portrayals; some have been noted to perpetuate patterns of representation around ethnic identification, gender roles, citizenship, and socio-cultural ties. The consumption trends and effects these South Asian American portrayals have on South Asian American second-generation youth is largely unknown. The purpose of this study is to collect data concerning the media consumption patterns of our defined population of South Asian American youth, and how they negotiate gendered portrayals of their ethnic compatriots in their formation of ethnic identity. Using socialization theories and other data from previous ethnographies of South Asian Americans, we employ online surveys and personal interviews geared towards monitoring the consumption of South Asian American media portrayals and their effects on how South Asian American youth view themselves and their community. Findings of this study are among the first in the field of South Asian American Studies to indicate how South Asian American media portrayals affect the growing number of South Asian American youth, and how the pervasive growth of South Asian American media portrayals may be affecting the gendered ethnic identity formation of youth who consume these types of media.

  • Blood Purity and Scientific Independence: Blood Science and Postcolonial Struggles in Korea, 1926-1975
    Science in Context (2019), 32, 239–260 doi:10.1017/S0269889719000231 RESEARCH ARTICLE Blood purity and scientific independence: blood science and postcolonial struggles in Korea, 1926–1975 Jaehwan Hyun Max Planck Institute for the History of Science, Berlin, Germany Email: [email protected] Argument After World War II, blood groups became a symbol of anti-racial science. This paper aims to shed new light on the post-WWII history of blood groups and race, illuminating the postcolonial revitalization of racial serology in South Korea. In the prewar period, Japanese serologists developed a serological anthro- pology of Koreans in tandem with Japanese colonialism. The pioneering Korean hematologist Yi Samyŏl (1926–2015), inspired by decolonization movements during the 1960s, excavated and appropriated colo- nial serological anthropology to prove Koreans as biologically independent from the Japanese. However, his racial serology of Koreans shared colonial racism with Japanese anthropology, despite his anti-colonial nationalism. Keywords: race; blood groups; racial serology; decolonization movements; scientific nationalism; South Korea Introduction In 1969, prominent South Korean hematologist Yi Samyŏl(李三悅, 1926–2015) published an article on blood-group research to prove Koreans’“blood purity” (純血) and to contend “scientific independence” (科學的自主性) (Yi 1969, 57).1 In this paper, he surveyed the blood-group dis- tribution of Koreans, including state-of-the-art blood-group systems like the Diego antigen system.2 Based on his intensive research, Yi proudly claimed, “Koreans are a racially homogeneous nation (單一民族) and have not been mixed with the blood of neighboring ethnic groups,” while the Chinese and the Japanese were “a mongrel race (雜種) whose blood is mixed” or “a racially mixed nation” (混合民族) (ibid., 64).3 At the same time, Yi contended that Korean scientists would have to achieve scientific independence from Japan and the United States in order to estab- lish Koreans as biologically independent from the Japanese.

  • Ancestor Veneration and Its Possibility.Pdf
    ANCESTRAL VENERATION AND THE POSSIBLITY OF ITS INCORPORATION INTO THE JUDEO-CHRISTIAN FAITH Abstract: In Nostra Aetate – one of the 16 documents of the Second Vatican Council – the Catholic Church firmly declares: “The Catholic Church rejects nothing of what is true and holy in other religions. ….. The Church, therefore, urges all her sons and daughters to enter with prudence and charity into discussions and collaboration with members of other religious faith traditions… (cf. NA. 2). The so- called ‘other religions’ as stated by Nostra Aetate includes traditional religion in the form of ancestral veneration. It is still widely and popularly practiced by Christians of various ethnic groups in Asia and Africa as well as in other parts of the world – Latin America, Melanesia and Australia (the Aborigines). Despite the suppression and expulsion done in the past, this religious tradition is still able to survive and continue to demonstrate its vital force in the lives of many Asians and Africans, including those who have embraced the Christian faith. In this article we argue that ancestral veneration does not contradict the Christian faith. It has a place in the Christian faith and should be incorporated into, at least, in Catholic Christian devotion. Note: artikel ini dimuat dalam EXCHANGE: Journal of Missiological and Ecumencial Research, Vol. 36 No.3 2007, Utrech, Nederland, pp. 246-280. Alexander Jebadu 1. INTRODUCTION Religious practice1 that centres in venerating ancestors or the living dead in general still to this modern day continues to play a significant role in the life of many Christians around the world especially in Asia and Africa as well as in Latin America, Melanesia, Australia (Aborigines) despite the maltreatments and prejudices launched both by a number of scholars and by some pastoral agents of the church.
