    Youth from immigrant communities may experience barriers to connecting with schools and teachers, potentially undermining academic achievement and healthy youth development. This qualitative study aimed to understand how educators serving Somali, Latino, and Hmong (SLH) youth can best promote educator-student connectedness and positive youth development, by exploring the perspectives of teachers, youth workers, and SLH youth, using a community based participatory research approach. We conducted four focus groups with teachers, 18 key informant interviews with adults working with SLH youth, and nine focus groups with SLH middle and high school students. Four themes emerged regarding facilitators to educators promoting positive youth development in schools: (1) an authoritative teaching approach where teachers hold high expectations for student behavior and achievement, (2) building trusting educator-student relationships, (3) conveying respect for students as individuals, and (4) a school infrastructure characterized by a supportive and inclusive environment. Findings suggest a set of skills and educator-student interactions that may promote positive youth development and increase student-educator connectedness for SLH youth in public schools.

    Full Text Available Over the past several years, Hmong in the United States have gained prominence for their increasing involvement in politics. Most of the attention has understandably focused on Fresno, California and St. Paul, Minnesota, home to the two largest Hmong populations in this country. While the Hmong communities in both cities are similar in size and have made significant political progress as evidenced by the election of Hmong candidates, the Hmong community in St. Paul has made greater inroads in the political realm. In addition to the elections of two Hmong candidates to the Minnesota State Legislature and two to the St. Paul School Board, the Hmong community in St. Paul has been able to engage local and state governments in Minnesotato address issues that affect the Hmong community. Through interviews, census data, and newspaper coverage of political campaigns, I show that Hmong in St. Paul have achieved greaterrepresentation in local and state governments and received greater support from government officials than Hmong in Fresno because Minnesota offers a social, economic, and politicalcontext that is favorable to fostering Hmong political involvement. Compared to Hmong in Fresno, Hmong in St. Paul have higher levels of socioeconomic resources and are more visible given their large size relative to other minority groups. They live in a region with consistently high levels of political participation and have political candidates who devote resources to mobilizing the Hmong community. Moreover, the Hmong vote has been critical to the success of Hmong candidates in St. Paul, an indication of the increasing political clout of the Hmong community there and a major reason why politicians in Minnesota are more willing to respond toissues that affect the Hmong community. Overall, this study highlights the importance of local and regional context in understanding the political incorporation of immigrants.

    Nearly 13% of the U.S. population is comprised of foreign-born individuals, with Somalis constituting one of the largest resettled groups. Research suggests that, among Somali refugees, rates of mental illness are high. Yet research shows Somalis underutilize mental health services. Understanding their perceptions of mental illness and its cures may help practitioners to design more effective treatments for this population. Thus, this pilot study investigated Somali refugees' perceptions of mental illness and its treatments. Using purposive sampling, this qualitative study interviewed 20 Somali refugees using a semi-structured interview guide. Qualitative analysis yielded participants' perceptions of mental illness through their descriptions of physical symptoms accompanying mental illness, the stigma of mental illness, causes of mental illness, medical and non-medical treatments for mental illness, spirit possession causing mental illness, and the Qur'an as treatment for mental illness. Such information may help practitioners in the United States approach Somali clients in the most culturally coherent manner.

    Since the onset of the Somali civil war in 1991, more than 1 million Somalis have been displaced from Somalia. Minnesota has the largest Somali population in the U.S. Informal tobacco prevalence estimates among Somali populations in the U.S. and the United Kingdom range from 13% to 37%, respectively. Little research has been conducted to determine the extent of Somali tobacco use. This paper reports the results from a knowledge, attitudes, and practices (KAP) survey conducted and analyzed in 2009 that explores tobacco use and estimates prevalence among Somali adults aged ≥ 18 years in Minnesota. Modeled after validated state and national tobacco use surveys, the survey was adapted for Somalis and administered to ethnically Somali adults (N=392) from 25 neighborhood clusters in Minnesota. Participants were chosen through probability proportional to size and multistage random sampling methods. Estimated prevalence for cigarette use among Somalis was 24% (44% among men, 4% among women). Ever users were significantly more likely to be men, have attended college, and have friends who used cigarettes (pIslamic prohibition of tobacco was protective and affected current use and future intention to use tobacco (peducation levels. Positive peer pressure and religion are protective factors from tobacco use and should be integrated into prevention and cessation programs. Copyright © 2012 American Journal of Preventive Medicine.

    1995-10-01

    This study of the Hmong in Laos is based on ethnographic research conducted during a three week stay in the Nong Het district of Xieng Khouang province. Information was collected on the household agricultural economy, village and household movement, family composition and change, cropping and animal husbandry, and environmental resources. The study area east of the Mekong River and near the Vietnamese border is an infrequently studied area. Findings differ from the ethnographic literature that portrays the Hmong as migrating frequently as swidden fields are exhausted, as living in large extended families, and as polygynous. The Hmong are the second largest minority in Laos (231,000), but are only 0.1% of Thailand's total population (90,000). There are 558,000 Hmong in Vietnam, but 5 million in China. Most rural Hmong in Laos produce opium as a necessary crop for sustaining their household farming economy. Although areas near the study area were involved in major military action during 1960-73, the study area received minimal disruption. Four studies of the Hmong in Laos and Thailand indicated that the Hmong stayed at one residence about 7 years, that residence varied from 6-16 years, and that settlements were short-lived. Household size ranged from 4 to 47 households. The Hmong in this study were more sedentary. In 1990, the villages averaged about 45 households. The population ranged in age from 19 years to 87 years. The Hmong had a high birth rate and a high mortality rate due to poor diet and lack of adequate medical care. 45% of the Nong Het population were aged under 14 years, which suggests a baby boom after the war. The dependency ratio was very high. Polygyny was uncommon. Of the 154 households, the average size was small at 7.40 persons. 71% were nuclear families. Patrilocal residence after marriage was still practiced, but the time spent in the father's home was reduced. The findings suggest that the Hmong are likely to become sedentary due to limits on

    Full Text Available The Hmong are a transnational ethnic people, because of their dispersal from China into Southeast Asia in the early 19th century and from Southeast Asia to Western countries from 1975 onward. However, even within the context of Southeast Asia and southern China, the Hmong are a transnational ethnic group, due to state boundaries and the enforcement of international laws.Scholars speak as though the Hmong population has crossed political and legal borders by their movement across state boundaries and international borders. However, I argue that it is the political, social, and legal borders that have cut across the Hmong people and subjected them to be citizens of different modern nation-states. Even in the present time, these borders still, and continuously, play important roles that cross and divide the Hmong people into distinctive subgroups and fragments. In this article, I will start by describing the generally understood situation of Hmong being across national borders, and then will explain my argument that borders are across the Hmong.

    Full Text Available In this paper, we describe a participatory workshop we facilitated on the diversity of Hmong sexualities and sexual norms – including our preparation leading up to the workshop and a summary of what we learned – at the 2015 Hmong National Development conference, which marked the 40th year that Hmong have been in the U.S. We also describe our positionalities and stakes in the matter as they helped to frame discussion. Topics discussed during the workshop included the “repressive” construction of “Hmong culture,” gender inequalities, desirability, sexual mores, LGBTQ identities and homoeroticism, virginity, sex acts and pornography. Participants engaged in lively conversation about issues of marriage, reproduction, hookups, sexual play, age and generation, sex education, and exclusion versus tolerance, amply underscoring the multiplicity of viewpoints that are represented among Hmong Americans. Finally, we raise the need for more community dialogues and more in-depth academic inquiry into Hmong sexualities.

    Løvlie, Astrid Louise; Madar, Ahmed Ali

    2017-06-01

    Postpartum depression (PPD) has been described as the most common complication experienced postpartum, affecting about 10-15 % of all new mothers. Factors like a history of mental illness, and experienced recent adverse life events has been associated with an increased risk for developing PPD. Immigrant women in Western countries have been found to have a marked higher prevalence of PPD compared to the general population. In Norway the prevalence of PPD in the general population has been found to be around 8-10 %, and among Pakistani immigrants a rate of 7.6 % was found. Somali people in Norway are the second largest immigrant group in Norway with a non-Western background. No study on PPD and associated factors among Somali women has been found in the literature. The aim of the study was to assess PPD and associated factors among Somali women in greater Oslo region, Norway. A cross-sectional survey was conducted; recruiting new mothers through all maternity wards in the Oslo region. Data was collected with interview-administrated questionnaires. PPD was assessed using Edinburgh Postnatal Depression Scale (EPDS), defining those scoring ≥10 to have a possible PPD. Of the 80 eligible women identified, 39 (49 %) consented to participate, and completed the study. Of the 39 respondents 3 (7.7 %) were assessed to have a possible PPD. Most important associated factors found were history of mental illness, having experienced technical assistance during delivery, self-rated health and experienced economical problems last 12 months. A low prevalence of PPD was found, and both the prevalence and its associated factors should be interpreted with caution. The associated factors do not have enough power to give any strength to the associations. However, some of the results can be used in develop new hypotheses with regard to PPD among Somali women as immigrants in a Western society.

  13. Hmong transnational identity: the gendering of contested discourses

    Directory of Open Access Journals (Sweden)

    2005-01-01

    Full Text Available Hmong women throughout the diaspora are increasingly expressing ‘what it means to be Hmong’ and ‘what it means to be a Hmong woman’ in a variety of media that constitute western popular culture. At the same time, Hmong women residing in different nation-states live Hmong femininity differently. This paper explores the contested nature of Hmong identity through an exploration of discourses and practices at global and local levels, with a particular emphasis on their gendered dimensions. The paper argues that global narratives of Hmong identity are analytically distinct from, but empirically intertwined with, the constructions of Hmong identities across transnational social spaces. Through a focus on Hmong in Australia and the United States, the paper highlights the significance of place, generation, gender, religion, class and status as axes of contestation and debate in the construction of Hmong identities.

    Full Text Available This author attended the first day of the 2005-06 Hmong New Year in Fresno,1 which was held during the week of December 26 to 31, 2005; and found it to be strongly influenced by commercial, political and informational/educational activities. This was the 30th annual Hmong New Year event celebrated in the United States and it appears to have developed itself into a unique Hmong American festival. It included many elements and traditions from the pre-1975 New Year of the Hmong of Laos. This includes the youth displaying their Hmong traditional costumes, the ball tossing, and the singing of traditional Hmong songs. On the other hand, this New Year event was also dominated by commercial, entertainment, political and informational/educational activities that appeared to be influenced by the American and Western concepts of the market economy, technology and freedom of expression. The Hmong New Yyear in the United States has become a festival that embraces two cultures, nurtured by the Hmong Diaspora and the long-time Hmong strengths of adaptability and flexibility.

    2012-01-01

    Due to its negative impact on public health, female circumcision (FC) has gained increased attention from international communities and the Norwegian public in recent decades. In 1995, the Norwegian government outlawed the practice and simultaneously developed a package of measures aimed at preventing and ultimately eradicating FC in Norway. Like many other Western countries, immigrants of Somali descent constitute the largest immigrant group in Norway from countries with FC traditions. Although this immigrant group is often perceived as a cultural society that supports FC generally as a practice, there appears to be a lack of studies that explore the impact of acculturation and the Western social context on Somali immigrants' attitudes toward the practice. Against this background, this paper explores the attitudes of Somalis living in Oslo, Norway to the practice of FC. Findings from this qualitative study indicate that Somalis in Oslo have, to a large extent, changed their attitude toward the practice. This was proven by the presence in Oslo of a large number of Somali parents who left their daughters uncut as well as Somali girls, boys, men, and women who attribute being uncircumcised a high status. This study adds to the knowledge of the process of abandonment of FC among immigrants in the Western countries. The study highlights the success that has been achieved in improving attitudes toward the practice of the Somali community in Oslo, Norway, as well as emerging challenges that need to be addressed further.

  3. The Mediated Figure of Hmong Farmer, Hmong Studies, and Asian American Critique

    Hui Niu Wilcox

    2012-01-01

    Full Text Available The objective of this article is two-fold: First, it argues for critical engagement between Hmong Studies and Asian American Studies. Second, to illustrate the productivity of such engagement,this article analyzes the media coverage of an incident involving Hmong American farmers and their white neighbors in Eagan, Minnesota, June 2010. The focal question is how media discourses around farming and immigration serve to racialize Hmong American identities. Thisanalysis shows that Hmong Americans experience “Asiatic racialization” in that they are either discursively cast outside of the imagined American nation, or included contingent uponassimilation and conformity. Critiquing both the exclusionary and assimilative narratives, this article explicates the inherent contradictions of the U.S. nationalism, referencing both existingHmong Studies literature and Asian Americanist discourses on race and nation. Both bodies of work foreground the historical and social construction of identities, as well as the simultaneous,intertwined workings of race, class, gender/sexuality and nation. Critical dialogues could generate new ideas and possibilities for both Asian American Studies and Hmong Studies.

    Full Text Available This study examines acculturation processes among Hmong who live in Eastern Wisconsin by using the East Asian Acculturation Measure (EAAM, which was developed by Barry (2001. The results indicated that in terms of Acculturation, Hmong ranked highest in integration, then separation, assimilation, and lastly marginalization. Questions on each dimension of integration, separation, assimilation, and marginalization were analyzed and positive correlations were found between the youngest of the generations, the length of residency in the United States, and the ability to speak, read, and write in English. In contrast, the older the age of the participant when they came to the United States had a positive correlation with separation. The ability to speak, read, and write in English had a positive correlation with assimilation, and the older the age of coming to the United States had a positive correlation with marginalization. Assimilation and separation had a positive correlation with marginalization, while integration had a negative correlation with marginalization and a positive correlation with assimilation, and separation had no correlation with marginalization. Results are discussed in regards to previous Hmong acculturation studies.

    Full Text Available In traditional Hmong life, women produced complex textiles as markers of clan identity and cultural values. Paj ntaub (flower cloth, created by embroidery, appliqué, reverse appliqué, and indigo batik (among the Blue or Green Hmong, were primary transmitters of Hmong culture from one generation to the next over centuries. Clothing, funeral and courtship cloths, baby carriers and hats were designed with traditionally geometric, abstract patterns Hmong could understand as a shared visual language within an oral culture.This photo essay introduces the author’s twenty-five year fascination with paj ntaub and documents a trip to Laos and northern Thailand in November/December 2009 to discover whether story cloths were being produced in Hmong villages in Laos or if story cloths remain a product of refugees only. The researcher also hoped tolearn whether traditional Hmong clothing is still produced and worn in the Laos, to observe how Hmong textiles are made and consumed for a tourist market, and to discover possible sources for the dramatic shift in paj ntaub visual language from symbolic abstraction to pictorial representation.

    Full Text Available This study was designed to investigate one of the newest refugee groups to the Midwestern United States, the Hmong refugees from Laos, China, Vietnam and Thailand. This study broadly examines how multigenerational Hmong families are adjusting and adapting to life in Rochester, Minnesota. The following questions guided this study: (1 What effect does non-voluntary migration have on the acculturation levels as measured by cultural awareness and ethnic loyalty of the Hmong in Rochester, Minnesota? (2 How do the Hmong perceive their host Anglo culture? (3 How do the Hmong adjust to their host social system in the United States? (4 How much do Hmong learn about their new environment? (5 How do the Hmong retain traditions within in the United States?Qualitative interviewing through in-depth individual interviews and participant observation was the method of data collection. Participants were recruited through purposive sampling, volunteering, and snowball sampling techniques. Criteria for inclusion in this study were: 1 Being Hmong; 2 Residing in Rochester, Minnesota, and; 3 Being at least 13 years of age or older. Grounded theory methodology was the primary tool of data analysis.The findings clearly demonstrated that the Hmong subjects interviewed for this study showed a high degree of discrepancy between the acculturation levels based on age and country of origin from point of migration. This discrepancy has created an acculturation gap, which is related to the younger Hmong’s increased identification with the American culture and their decreased identification with their family’s culture of origin. This shift has created family difficulties and communication gaps between the generations.

    Full Text Available Many Hmong continue to believe in the efficacy, and commission the practice by shamans of, some of the more important traditional rituals, such as marriage rites (kab tshoob kev kos, "soul calling" (hu plig, healing rites (ua neeb or khaw koob, worshipping the "house spirit" (teev xwm kab, and funeral rites (kev ploj tuag. Certainly, however, there are those Hmong, especially among younger generations, who either choose not to participate in such rituals, or who participate in them without any clear comprehension of the deeper meaning or details; indeed, without any strongly held beliefs regarding the cosmological system which is the ritual's foundation, underpinning and supporting the call for the many actions, gestures, offerings and recitations which, in the final analysis, constitute the bulk of any such performance. This philosophical ambivalence on the part of modern celebrants renders the position of ritual in Hmong society somewhat problematic. In addition, the various Hmong clans have, in the past, of necessity resided in divergent geographical locales, and, as a result of this and other factors, have often espoused divergent, philosophically and culturally heterogeneous, beliefs. This, taken together with the fact that Hmong customs have been orally transmitted down the generations, has had the result that there may be several versions of the meaning, and method of performance, of any given ritual.The presentation that follows will discuss the "Dab Pog Couple" story as it bears upon the origins of Hmong cultural tradition and embedded social values. Such a consideration will, at the same time, serve to introduce and elucidate many of the meanings behind, and values attached to, Hmong rituals in general and will thus provide a contribution to the understanding of these rituals and their relation to Dab Neeg (Folk Legends within the Hmong cultural studies scholarly literature.Briefly stated, the Hmong believe that the "Dab Pog" couple

    Full Text Available This study examined family financial management in the Hmong community through the analysis of 11 in-depth interviews with Hmong professionals who worked in the area of finance. The findings revealed that as the Hmong made the transition from an agricultural economy in Laos to the complex economic system in the United States, they have learned to adapt to their environment. First generation immigrants continue to live fairly simple lifestyles and havemaintained their strong value of saving money. The 1.5 generation integrates the Hmong value of saving with their knowledge about the U.S. financial system, resulting in savvy financial investments. The 2nd generation, born and raised in the U.S., has been primarily influenced by the U.S. consumer culture, resulting in perceiving wants as needs. Thus spending is a higher priority than saving.

  16. Searching for the Hmong People’s Ethnic Homeland and Multiple Dimensions of Transnational Longing: From the Viewpoint of the Hmong in Laos

    2010-01-01

    Full Text Available This paper examines how Hmong people in the diaspora imagine each other and develop diverse and multidimensional types of longing in the absence of a “true” ethnic homeland. Even before the Hmong dispersed around the world after the Vietnam War, they never identified or agreed upon a “true” ethnic homeland. As a result, Hmong people have inevitably developed various other types of longing. The objects of these longings have been conceptually expanded to include a Hmong culture, a powerful leader, and a future time when Hmong will again be reunited. In this sense, I will examine the way Hmong people express their perspectives on their objects of longing in the absence of a “true” ethnic homeland by focusing on the viewpoints of some Hmong people residing in Laos. Based on my observations and analysis, I also propose to rethink the limitations of the dominant view about how Hmong imagine their ethnic homeland.Although current theoretical perspectives of transnationalism and “imagined community” have contributed to an understanding of the Hmong people’s imagination and their diasporic ethnic identity, those views cannot fully explain how Hmong people’s longing is not just associated with the lost homeland but can have multiple directions and meanings. These different types of longing expressed by the Hmong people suggest that diasporic communities can be maintainedwithout a territorial ethnic homeland.

  17. Political Transmigrants: Rethinking Hmong Political Activism in America

    Directory of Open Access Journals (Sweden)

    Nengher N. Vang, Ph.D

    2011-12-01

    Full Text Available Since the initial resettlement of the Hmong in the United States in the mid-1970s, they have maintained strong political and military relationships with the Lao People‘s Democratic Republic (LPDR. Yet, there is little research on that relationship and the involvement of the Hmong in the United States in political developments in Laos. Most works on Hmong political activism have focused on the electoral participation and representation of Hmong Americans in relation to American domestic politics. In this article, using archival, ethnographic, and interview data that I have collected between 2006 and 2009 in Laos, Thailand, and the United States, I describe and analyze the non-domestic or transnational form of Hmong American political expression and participation. I argue that Hmong political activism in America not only was transnational from the outset, but that their transnational involvement in political developments in Laos and their relations with the Lao PDR government also had a significant impact on their ethnic politics. Many Hmong political activists made their entry into ethnic politics through the door of transnational politics, and many were motivated by transnational political issues to participate in domestic American politics. By exploring their transnational involvement in political developments in Laos and their relations with the Lao PDR government, we get a more complete and dynamic understanding of Hmong political activism in the United States than is possible by focusing exclusively on domestic and electoral participation. Examining their transnational politics also allows us to see the transnationality of not only their culture, identity, and community but also that of their political activities and aspirations.

    Conclusion: Many Hmong people in the United States believe that both traditional and Western health care practices are effective, but when health professionals do not address differences in language, communication, and beliefs about health, trust between the provider and client may erode. The findings of this study provide new insight into the importance of cultural accommodation to improve early cancer detection in the Hmong community.

    2008-01-01

    Full Text Available This study utilizes a qualitative method to explore the critical reflections of Hmong parents helping their children maintain their native language. Specifically, it examines parents’ thoughts, feelings and experiences related to Hmong language maintenance. Findings reveal that Hmong parents worry about their children losing their ability to speak their native language. They believe that maintaining the Hmong language provides advantages in achieving academic success, attaining careers, and continuing to serve as role models in the community. Parents stressed the need to use Hmong at home in order to help their children develop and maintain the language. They reported some successes in doing so, while acknowledging several challenges.

  1. Commentary: The Hmong and their Perceptions about Physical Disabilities: An Overview and Review of Selected Literature

    2010-01-01

    Full Text Available The Hmong are one of the fastest growing populations in Central California. Hmong refugee families arrived in Fresno in the late 1970s facing a variety of challenges regarding their traditional health beliefs and the customs of mainstream Western biomedicine. Differing and sometimes conflicting perceptions about physical disabilities have resulted in painful misunderstandings between Hmong families and Western health care providers. The aim of this paper is to present a review of some of the Hmong health belief literature concerning physical disabilities in children. It also includes commentaries from those who work with the Hmong families of physically disabled children.

    2006-01-01

    Full Text Available In 1992, Ms. Dia Cha – then a graduate student in anthropology at Northern Arizona University – traveled to Chieng Kham Refugee and Napho Repatriation Camps in Thailand, and the village of Ban KM 52, inVientiane Province, Laos, to research issues concerning the repatriation to Laos of Lao Lum and Hmong women refugees. This article, originally written upon the return from these travels and in partial fulfillment of the requirements for her Master of Arts degree in Applied Anthropology, considers the findings made and the insights achieved on this journey of discovery. In particular, the work discusses changes and continuity in the lives of Lao Lum and Hmong refugee women in the camps. Also addressed in considerable detail is the impact of the author’s status as an educated Hmong-American woman and former refugee on her interactions with female and male informants residing in the two refugee camps. Ms. Cha, who spent much of her early life in such refugee camps as are herein described, has, in the intervening period, become Dr. Dia Cha, Associate Professor of Anthropology and Ethnic Studies at St. Cloud State University, St. Cloud, Minnesota, USA. The research project she describes was funded by the United Nations Development Fund for Women and executed by the American Friends Service Committee (The Quaker Services. Ms. Jacquelyn Chagnon joined Ms. Cha during the second phrase ofthe research, in Napho Repatriation Center, and later in Laos; however, the following article, produced originally in 1992, was written solely by Ms. Cha.

    Full Text Available Early studies of Hmong refugees in the U.S. indicated high rates of mental distress related to post-migration stressors such as grief and loss, poverty, and social adversity. This study explores the mental health status of two generations of Hmong Americans 38 years after their first migration. The relationship between acculturation and mental health of 191 1st and 2nd generation Hmong are reported. Results indicated relatively low reports of depressive symptoms and medium to high rates of acculturation to American society. The results are unrelated to demographic factors indicating resilience and adaptation to Western society despite age and generational status and maintenance of culture of origin

    Full Text Available Prepared for the Seminar on Cultural Factors in the Prevention and Promotion of Gender-Based Violence held at UNESCO Bangkok on 17-18 May 2012, this article presents the current state of the subject in the patrilineal, patrilocal and patriarchal (Hmong society.After delineating carefully (Hmong GBV through rape, marriage customs, domestic verbal and physical abuses and, in some cases, murder, the author investigates the roots of GBV in different directions: gender asymmetry and inequality; tribal culture and the clan system; the function of the bride price; women’s social mobility in the U.S. and values clashes with American values. After a thorough anthropological analysis, the author concludes that GBV has nothing to do with the clan system, the backbone of the tribal society, but rather involves a long-lasting borrowing of Chinese patterns from the (Hmong past in Imperial China, which could be amended. Gender inequality will hopefully regress if shame, a powerful means ofsocial control among the (Hmong, is used to deter GBV.

    Victoria Udalova

    2006-01-01

    Full Text Available This paper explores the boundaries of the Hmong community as measured by different categories in 2000 U.S. census data. Following careful assessment of detailed Census data, the authors conclude that theusual criterion used to identify a person in the data as Hmong is too narrow, and that a broader, more inclusive definition more accurately delineates the Hmong ethnic group. The authors propose that anyonewho reported in the Census that his or her race, ancestry, or language was Hmong should be included in the Hmong community. This more inclusive method provides evidence that the Hmong populationenumerated by the 2000 U.S. census was about 18% larger than the figure that is usually reported.

  10. Caught Between Cultures: Hmong Parents in America’s Sibling Society

    Directory of Open Access Journals (Sweden)

    Tamara L. Kaiser

    2005-01-01

    Full Text Available Based on a qualitative study of the Hmong Community in the Twin Cities of Minneapolis and St. Paul, this paper addresses the conflict between the traditionally hierarchical and patriarchal Hmong culture and those aspects of American culture that elevate freedom and equality over, not only patriarchy, but over hierarchy in general. Although this conflict has forced the Hmong community to change in some positive ways, it also creates great challenges for parents and their children. Distorted values of “freedom” and “equality,” promoted by much of American culture, compromise the ability of many Hmong to be effective parents. A comparison of traditional Hmong parenting with what author Robert Bly calls America’s “sibling society” demonstrates that both Hmong and mainstream families and society are hurt by a general rejection of authority and would greatly benefit from recognizing the value of hierarchy based on experience, genuine accomplishment and wisdom.

  11. Diaspora and the Predicament of Origins: Interrogating Hmong Postcolonial History and Identity

    Directory of Open Access Journals (Sweden)

    Gary Yia Lee

    2008-01-01

    Full Text Available This paper examines two basic issues that have been of major concern to the Hmong in the diaspora: (1. What is their historical and geographic origin; and (2 are the Hmong part of the Miao nationality in China, and should they accept being known under this generic name?There have been many theories about where the Hmong originally came from, ranging from Mesopotamia in the Middle East during Biblical times, the North Pole, Siberia, to Mongolia and China. This paper consolidates these many propositions with their supporting evidence, and draws its own surprising conclusion as to the real location of the original homeland of the Hmong. Depending on what they regard as their origin and which history they wish to be aligned with, the Hmong may have to reconsider being known as Miao or Meo, a name which most have vehemently rejected because of its derogatory connotation, especially among the more politically conscious Hmong now living in Western countries.

  12. Using Mammography Screening: Hmong Women’s Perceptions and Beliefs

    2010-01-01

    Full Text Available Breast cancer is the second leading cause of cancer deaths among all women in the United States. Although mammography screening has been shown to be effective in detecting breast cancer, Hmong women, one of the Asian American/Pacific Islander subgroups, have a very low screening rate. The purpose of this study was to explore factors that influence Hmong women‘s willingness to be screened for breast cancer. Grounded Theory methodology guided the analysis of fifteen qualitative interviews with Midwestern Hmong women between the ages of40-64. Regardless of age, length of US residency, and language spoken, the results showed one core theme and three interrelated themes regarding the women‘s decision to seek mammographyscreening. The three interrelated themes of Breast Health Messages, Screening Barriers, and Screening Facilitators can have negative and/or positive influences on the core theme of mammography-screening decision-making processes. The first related theme of Breast HealthMessages included professional and lay breast health messages. The second related theme, Screening Facilitators, included breast health messages from professionals, abnormal findings, social support, risk for getting breast cancer, doctor‘s recommendations, and insurance. The third related theme, Screening Barriers, identified symptomatic health seeking behavior, instrumental barriers, fear, social influence (which included lay breast health messages, use of traditional Hmong healing practices, embarrassment, and perception of breast cancer risk. This study suggested that the healthcare professionals need to use a culturally sensitive and multidisciplinaryapproach to provide breast health education as well as to assess and provide instrumental support, while encouraging social support to influence Hmong women to attain mammography screening.

  13. Chao Fa Movies: The Transnational Production of Hmong American History and Identity by Ian G. Baird

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available Films made by and for particular social and ethnic peoples can reveal a great deal about identity issues. Here, I examine the cultural production, the content, and the socio-cultural and political significance of three Chao Fa-inspired Hmong films produced at Khek Noi, Thailand by Hmong American producers working with largely Hmong Thai actors. The first two, Chao Fa 1 and 2, were directed in 2009 by Kou Thao. The third, Vaj Tuam Thawj – The Legend of Chao Fa, was put together by Jimmy Vang, in 2010. Even though these Chao Fa films are fictional, they attempt to depict events and circumstances that are familiar to many first generation Hmong Americans, and they can muster strong emotions from people who see them as depicting factual history. In addition, just like many other American youth, many 1.5 generation Hmong are tied together by shared media experiences, including Hmong movies. Thus, the Chao Fa movies are important for producing and reproducing, reinforcing and dispersing ideas related to Hmong American identity and culture. They tell stories of the Hmong being oppressed by many different groups, and this history suggests why many Hmong—not only the Chao Fa—have long desired the type of independence and freedom from prejudice and discrimination that they imagine would come if the Hmong only had their own nation state.

    To determine the frequency and perceptions of herbal medicine use among Hmong Americans. Cross-sectional telephone survey. Sacramento, California Hmong community. Out of 118 subjects reached, 77 (65.3 %) reported lifetime use of herbal medicines. A majority of respondents agreed that herbal medicines were able to treat the body as a whole. Respondents felt that a leaflet of information indicating uses/side effects would be important to include for herbal medicines. Herbal medicine use was commonly reported among Hmong Americans. Thus, health care providers should be encouraged to discuss these alternative medicines with their Hmong American patients.

    2009-01-01

    Full Text Available We review Timothy Vang’s dissertation on the growth and decline of the Hmong Christian church. We argue that Vang’s arguments are methodologically and theoretically flawed. Furthermore, we try to show that his dissertation is not so much an objective analysis of Hmong religious adaptation, but rather an attempt to define and subjugate certain Hmong cultural and religious beliefs and practices as backward and inferior to Christianity. We suggest that it is these kinds of problematic arguments, often couched in academic language, that further perpetuate misinterpretations and misrepresentations about “culture” and “religion” in Hmong American communities.

    Full Text Available Student awareness, usage, and perception of academic support programs were examined among 55 Hmong college students at a large, public western university. Twenty-eight students had participated in one or more ASPs while 27 students had not participated in any ASPs. Those who had participated found the programs to be supportive with an average rating of 7.39 out of 10 (10 being most supportive. The majority of students who did not participate in ASPs reported that they were not aware of ASPs and their services. Results also show that the majority of Hmong college students perceived a lack of time to study, poor study habits, lack of money, lack of motivation, lack of direction on career goals, and poor time management to be obstacles for them in higher education. Based on the findings, it seems ASPs were not able to reach some Hmong students with their outreach efforts. However, those that they were able to reach found academic support services helpful, especially with financial concerns and direction on career goals.

    2013-05-01

    This qualitative study explored the barriers and facilitators of cancer screening among women of Hmong origin. Using a community-based participatory research approach, we conducted focus groups (n=44) with Hmong women who represented four distinct demographic groups among the Hmong community. The participants described sociocultural barriers to screening, which included a lack of accurate knowledge about the causes of cervical cancer, language barriers, stigma, fear, lack of time, and embarrassment. Structural barriers included attitudes and practices of health care providers, lack of insurance, and negative perceptions of services at clinics for the uninsured. Health care providers may require additional training and increased time per visit to provide culturally sensitive care for refugee groups such as the Hmong. Health-related social marketing efforts aimed at improving health literacy may also help to reduce health inequities related to cancer screening among the Hmong.

    2007-01-01

    Full Text Available This paper explores the contested nature of Hmong women’s traditional roles and the recent emergence of Hmong American women leaders by discussing Senator Mee Moua, who was elected to the Minnesota State Legislature in January 2002. She became the first HmongAmerican state legislator in the United States. The family and kinship system are the backbone of the Hmong community, around which Hmong culture is organized. The Hmong recognize kinship through the male line, and the household is the basic economic unit in the patriarchal Hmong social system. This study was intended to find out how Mee Moua perceives her identity in working with her constituents and the Hmong people in her community, why the patriarchal Hmong community in St. Paul supported Mee Moua’s campaign, and how sheearned the broad support of a diverse constituency in defeating a candidate that had been handpicked by St. Paul’s mayor. I argue that ethnic identity and the presentation of individuality as “Mee Moua” combined to make this Hmong American woman a successful bridge between two distinctive cultures.

A review of economic indicators across states and in relation to the U.S. population reveals that on an aggregate level, the Hmong American population’s socioeconomic status has improved significantly. The increases in income and earnings have, however, been shortchanged by external factors brought about partially by the financial crisis and its aftermath. Consequently, this begs us to question the extent to which such developments contribute to the overall economic well-being of Hmong Americans.

    To identify barriers to outdoor physical activity in winter among Somali youth in Maine. Despite the many proven health benefits of physical activity among children, such as cardiovascular fitness and health status as an adult, there has been a decrease in physical activity among children in recent years. Specifically, children who are of low socio-economic status or are from communities where many immigrants are at increased risk for developing obesity. Immigrants are also less likely to be physically active. There are many potential barriers to wintertime physical activity among Somali youth in Maine, such as lack of financial resources, transportation, proper winter clothing, and appropriate knowledge of winter safety, and language and cultural barriers. For females, different attire required for outdoor activity may be a barrier. Somali parents and children were recruited from Portland, Maine to participate in focus groups led by a trained facilitator with a Somali translator and cultural broker. Transcripts were coded using NVIVO software to identify barriers to physical activity among Somali youth outside in winter. Eight focus groups were conducted. Sixty-one Somali community members were recruited. Participants felt outdoor physical activity is important, but note that it is decreased in winter. Barriers to outdoor activity in winter cited by focus group participants were lack of resources, health concerns, gender barriers for females, and knowledge barriers. Concern over lack of supervision while children play outside was also cited. This study revealed many of the underlying beliefs, barriers and cultural issues that impact Somali families' intention to be active and ability to be active outdoors in winter. These findings can be used to generate research hypotheses and public health interventions regarding outdoor physical activity among Somali youth.

About 50 percent of the world container ships pass through the Gulf of Aden each year, 80 percent of those cargos coming from Europe. For this reason, the piracy issue affecting Somalia is a problem affecting EU member states’ security and economy. This paper is focused on the comprehensive approach acted by the European Union, with a special attention on proposing the implementation of programs against illegal fishing and waste dumping in order to fight Somali piracy. The evaluation of the military mission offers an overview on a solution for the near future, while the training missions and the development funds sustain the build-up of national tools and focus on the solving of the roots of the issue.

    Full Text Available This paper describes the development and implementation of a Hmong Cervical Cancer Intervention Program utilizing a patient navigation model to raise cervical cancer awareness for Hmong women through educational workshops and to assist Hmong women in obtaining a Pap test. Out of 402 women who participated in a baseline survey, the Patient Navigation Program was able to enroll 109 participants who had not had a Pap test in the past 3 years and had never had a Pap test. Through utilization of outreach, an awareness campaign and patient navigation support, at least 38 percent of 109 participants obtained a Pap test. Overall, 21 workshops and 43 outreach activities were conducted by the Hmong Women’s Heritage Association, leading to 63 percent of those enrolled in the Patient Navigation Program who could be contacted to obtain a Pap test.

    2013-12-01

    Full Text Available This study examines the ways that Hmong adolescents describe ethnic pride and how their descriptions are informed by perceptions of collective and social identities. Data from semi-structured interviews with 25 Hmong adolescents age 12-18 were thematically analyzed with attention to affective versus behavioral aspects of ethnic pride and the role of collective or social group identities in adolescent pride perceptions or expressions. Results indicate that Hmong adolescents view affective and behavioral components of ethnic pride as distinct and evaluated self and peer pride along these two dimensions. Moreover, pride was found to be defined as both an individual characteristic and a social construct, and the perception and expression of the term was informed by Hmong adolescent peer groups and collective identities.

    Full Text Available Background: A chart review at a urological office revealed that Hmong patients present with higher rates of kidney stones, uric acid stones, and complications from kidney stones than non-Hmong patients. In order to ultimately redress this health disparity, a conferenceof Hmong and non-Hmong health care providers decided that we needed to first understand the pertinent social, cultural, economic, and biological factors contributing to the disparity. This research project sought to elicit Hmong patients and family members’explanatory models, decision-making processes, and experiences with the health care system.Methods: We conducted in–depth interviews with 10 Hmong kidney stone patients, 11 family members of 9 patients, and 4 traditional healers. All 10 patients had received urological interventions, including ureteroscopy (8, percutaneous lithotomy (5 and nephrectomy (2. Some patients had postponed medical assistance (6 and had refusedprocedures (4. We qualitatively analyzed the transcribed and translated interviews with an Excel spread sheet and N6 computer software. Results were discussed with patients and a community advisory council.Results: Hmong concepts of kidney function and explanatory models of kidney stones are a blend of traditional and biomedical concepts. Kidney stones are understood as acute health problems caused by hard substances in water and food that stick to the kidney, which weak kidneys cannot excrete. Kidney stone sufferers do not know they have stones until they pass a stone or they see stones on X-rays, as pain or hematuria are non-specific symptoms. They prefer medications, including herbal medicines, to invasive urologicalprocedures. In making decisions about urological interventions, Hmong patients balance fear of disease (pain and renal failure with fear of doctors (complications from interventions and anesthesia. While patients have variable balance points to accept interventions, the basic philosophy of

    Corbett, Cheryl A; Callister, Lynn Clark; Gettys, Jamie Peterson; Hickman, Jacob R

    Increasing knowledge about the sociocultural context of birth is essential to promote culturally sensitive nursing care. This qualitative study provides an ethnographic view of the perspectives on birthing of Hmong mothers living in the highlands of Vietnam. Unique cultural beliefs exist in Hmong culture about the spiritual and physical world as well as ritual practices associated with childbearing. This includes variations of ancestor worship, reincarnation, and healing practices by shamans. Traditionally, Hmong families take an active role in childbirth with birth frequently occurring in the home. Situated within a large collaborative anthropology project, a convenience sample of 8 Hmong women, who had recently given birth, were interviewed regarding the perinatal experience. In addition, ethnic traditional birth attendants (midwives) and other village women contributed perspectives providing richly descriptive data. This ethnographic study was conducted during 6 weeks of immersed participant observation with primary data collection carried out through fieldwork. Data were analyzed to derive cultural themes from interviews and observations. Significant themes included (1) valuing motherhood, (2) laboring and giving birth silently, (3) giving birth within the comfort of home and family, (4) feeling capable of birthing well, (5) feeling anxiety to provide for another child, and (6) embracing cultural traditions. Listening to the voices of Hmong women enhances understanding of the meaning of childbirth. Gaining greater understanding of Hmong cultural beliefs and practices can ensure childbearing women receive respectful, safe, and quality care.

    Full Text Available Background. This pilot study explored health care providers’ perceptions of barriers to providing health care services to Somali refugee women. The specific aim was to obtain information about providers’ experiences, training, practices and attitudes surrounding the prenatal care, delivery, and management of women with Female Genital Cutting (FGC. Methods. Individual semi-structured interviews were conducted with 14 obstetricians/gynecologists and nurse midwives in Columbus, Ohio. Results. While providers did not perceive FGC as a significant barrier in itself, they noted considerable challenges in communicating with their Somali patients and the lack of formal training or protocols guiding the management of circumcised women. Providers expressed frustration with what they perceived as Somali patients' resistance to obstetrical interventions and disappointment with a perception of mistrust from patients and their families. Conclusion. Improving the clinical encounter for both patients and providers entails establishing effective dialogue, enhancing clinical and cultural training of providers, improving health literacy, and developing trust through community engagement.

    Full Text Available The state of Wisconsin, and in the broader context, the middle states of the United States experienced a large influx of Hmong families starting in the early 1980’s and into the 1990’s. With this influx a large number of young, Southeast Asian children entered the PK-12 classrooms, often with the support of bilingual aides. While many of the children flourished within this newer context, they were mostly guided in their classrooms by white, Anglo educators. Although theseeducators work to meet the needs of all children, there were few to no Hmong educators working with these same children in the PK-12 setting. At the same time, a number of Hmong young adults were serving as bilingual aides in these classrooms. Project Forward, a federally funded Title VII grant, has worked to create a shift in these roles, preparing Hmong college students to become educators in the PK-12 settings. In 1999, Central Wisconsin enrolled approximately3,200 Hmong children in the PK-12 schools; at the same time, Central Wisconsin employed merely seven Hmong teachers in the classrooms. The goal of the grant program described in this paper is to prepare teachers of Southeast Asian background for early childhood, elementary, secondary and K-12 classrooms. The Central Wisconsin grant has supported a total of 35 Southeast Asian students in their pursuit of teaching careers. Fulfilling the goal of preparingteachers who can serve as role models for Southeast Asian children in our schools has met with successes and struggles. This article presents consideration of the central factors affectingrecruitment, retention and preparation of Hmong pre-service teachers in Central Wisconsin. The article includes a brief historical examination of the immigration of the Hmong population intothe United States, a consideration of the Hmong culture as it affects recruitment and retention of pre-service teachers and evidence related to successes and struggles experienced by Project

Les chefs de guerre se disputent des portions du territoire en autant de repaires pour y organiser leurs trafics criminels. Expulsés de Mogadiscio par les milices des tribunaux islamiques, ils y sont revenus avec le gouvernement provisoire, réinstallé par l’Éthiopie. Toutefois, au Somaliland, au Nord, les autorités séparatistes ont rétabli la paix sur tout leur territoire, reconstruit les infrastructures et organisé des élections que personne n’a contestées, mais l’ONU, sous la pression conjuguée de la Ligue Arabe et de l’Union africaine, refuse de reconnaître l’indépendance de l’ex-colonie britannique. Après vingt ans d’indifférence à ce lointain conflit, l’État somalien est menacé de disparition.Since 1988 Somalia has sunk into an endless civil war. Warlords have been fighting over parts of the national territory in order to expand their criminal traffics. They were expelled from the capital by the Islamic court militias but they have returned to it when the Provisionnal Government of Somalia was restored by Ethiopia in Mogadisico. Under the pressures of the Arab League and of the African Union the United Nations have constantly refused to recognize the independence of Somaliland, a former British colony, despite its separatist government has brought peace on all their territory, rebuilt equipments and held fair elections. Twenty years of indifference to this remote conflict have threatened the Somalian state to death.

    2014-12-01

    Full Text Available Cancer is a growing concern for women in the Hmong community. Hmong women experience poor health outcomes for both cervical and breast cancer, largely due to low rates of screening and resultant late-stage at diagnosis. Both breast and cervical cancer screening are complicated by a multitude of social, cultural and environmental factors which influence health care decision-making and can otherwise serve to restrict access. We argue that community-engaged research, an orientation which prioritizes collaborative, equitable partnerships and community voice in identifying both problems and solutions, can be a valuable approach to helping address cancer health disparities for Hmong women. Using the Milwaukee-based “Healthy Hmong Women” project as a case example, we detail how the community-engaged approach implemented by the project partners was critical in identifying factors contributing to Hmong cancer disparities and appropriate interventions, as well as the overall acceptance and success of the project. Specifically, we discuss how this approach: (1 promoted community investment and ownership in the project; (2 facilitated the integration of local perspectives and experiences; (3 built capacity to address cancer screening disparities; (4 facilitated the creation of interventions targeting multiple ecological levels; and (5 framed the community as the foundation and driver of positive change.

    2007-01-01

    Full Text Available In December 2003, the U.S. State Department officially announced the acceptance of roughly 15,000 Hmong refugees from Wat Tham Krabok, Thailand, into the United States of America. The Hmong refugees were scheduled to be resettled for family reunification in established Hmong communities. As social science research on migration indicates, the existence of ethnic communities is crucial for a successful adaptation to a host society for newcomers. Ethnic communities thereby serve as a buffer zone and provide initial assistance,which is especially important when governmental integration measures are not sufficient. In the case of the Hmong refugee resettlement, the U.S. economic and social incorporation efforts were inefficient, due to cutbacks in U.S. Federal funding and welfare reforms, causinga greater reliance on the receiving Hmong communities. This raises a number of questions about how much an ethnic community can absorb and is able to bear in order to fulfill the newcomers’ needs. What are the limits and how does this affect the initial integration of thenewcomers?

    Full Text Available This study examines factors affecting the academic performance of Hmong students at Chippewa Valley Technical College in Eau Claire, WI. Factors specifically analyzed for their impact upon student success are socioeconomic status, family support, the use of academic support programs, and the influence of agents of socialization. Through the use of archival institutional data, Hmong students were compared to white students at CVTC in terms of their relative grade point averages, course completion rates, and retention rates. Data revealed significant disparities in grade point average performance between Hmong and white students. The data also showed that eligibility for financial aid was significantly higher among Hmong students, and that this difference was commensurate with educational performance gaps between the two groups. Additionally, online surveys were used to assess family support while attending CVTC, the role of academic support programs, and influential agents of socialization. Gender differences in grade point average performance and socialization also were analyzed. Implications of the study’s findings are discussed and recommendations for improving the performance of Hmong students are provided.

    2012-02-01

    Chronic hepatitis B virus (HBV) infection may result in cirrhosis and/or hepatocellular carcinoma and is one of the leading causes of mortality in Asian Americans including Hmong Americans. The Central California Valley is home to a huge Hmong population. To date, the true prevalence of HBV among Hmong is largely unknown. The aim of this study was to contribute to the limited data on HBV prevalence and its trends in Hmong population in the Central California Valley. Between fiscal years 2006 and 2010, a total of 219, 450 voluntary donors were identified at Central California Blood Center in Fresno. Of these, 821 (399 males and 422 females) were Hmong donors. A cross-sectional review of the HBV (hepatitis B surface antigen) positivity among all donors was carried out. Prevalence estimates with 95% confidence intervals (CI) were calculated. Ninety-two percent of Hmong donors were between age groups 16 and 35 years, and only 8% were ≥36 years. The overall prevalence in Hmong was noted at 3.41% (95%CI 2.3-4.9) compared to 0.06% (95%CI 0.05-0.07) in donors of all ethnicities. The calculated prevalence could be an underestimate of the true HBV prevalence in Hmong as the study enrolled only healthy blood donors with predominant younger age (≤35 years) population. These results underscore the persistent burden of HBV infection and potentially increased risk of premature death even in the second generation Hmong community of the Central California Valley. This study reemphasizes the unequivocal need to develop robust preventive and treatment strategies for HBV in Hmong community.

The sample included 209 Hmong adolescents living in Minnesota. There were 123 males and 86 females, ages 12 to 25 years. A survey was administered in several community agencies to adolescents that included their perspectives on the frequency and intensity of parent-adolescent disagreements on 28 issues and the problem behaviors of delinquent peer affiliation, gang involvement, truancy, and school performance. Results of hierarchical multiple regression analyses indicated the set of problem-behavior independent variables explained 26% of the variance in the frequency-intensity of father-adolescent conflicts and 21% of the variance in the frequency-intensity of mother-adolescent conflicts. Ideas for parent education in the Hmong community are discussed.

    Full Text Available Over the last thirty years since relocation, individual Hmong refugee communities in America have evolved with varying needs and outcomes adding to their complexity and diversity in the United States. There is a noted lack of research that examines these factors calling for further study to help understand the role of locality in the adjustment and diversity of refugees. This research begins a discussion on the unique Hmong adaptation in Texas. Unique and sometimes contradictory local factors deriving from thesocio-political environment of Texas have helped to shape a relatively small, but distinctively cosmopolitan community. This paper argues that Texan economic, environmental, and political differences have forged uncharacteristic understandings andchallenge conventional conceptions of what it means to be Hmong.

In this article I examine the impact of the exclusionary characteristic of cultural capital on refugee Hmong parents from Wat Tham Krabok. I highlight themes of uncertainty, powerlessness, gratitude and faith that parents repeatedly raised when speaking about their children's education. I suggest that paying attention to the affective emotional consequences of cultural capital is critical for understanding the outlook of refugee Hmong parents on their children's education.

    Full Text Available In education research, the analysis of the role of cultural capital has focused primarily on its role in parent involvement. Little attention has been paid to how cultural capital affects the attitudes or feelings of parents about their worth and roles as parents. In this article I examine the impact of the exclusionary characteristic of cultural capital on refugee Hmong parents from Wat Tham Krabok. I highlight themes of uncertainty, powerlessness, gratitude and faith that parents repeatedly raised when speaking about their children’s education.

    Stereotypical portrayals of the Hmong in Vietnam emphasize their apparently exotic customs related to sexual relationships and marriage and their alleged backwardness and resistance to change. Yet their history shows their ability to respond to changing socioeconomic contexts. This study details practices and aspirations concerning love, marriage and education among different generations of White Hmong women in the northern mountains of Vietnam, with particular attention to the perspectives of young women. We found a diversity of ideas and identified certain rapidly changing practices regarding marriage. Forced marriage through 'wife-snatching' was reported to have always been rare and its meaning and prevalence has seemingly been misunderstood by outsiders. Bride price payment was reported to be an important element of most Hmong marriages. Hmong girls studying at high school and secondary level were found to have particular aspirations pertaining to their marriage, education and career, but lacked confidence in their abilities to create their desired future. Findings also reveal how patrilocal residence following marriage places young women under the strict control of their husbands and parents-in-law, which is likely to contribute to their lack of self-esteem and sense of autonomy.

    Determine how dietary acculturation, anthropometric measures (height, weight, circumferences, and skinfolds), body mass index (BMI), and waist hip ratios (WHRs) are associated with blood pressure (BP) measures in Hmong children living in Minnesota. Acculturation was measured using responses to questions regarding language usage, social connections, and diet. Dietary assessment was completed using the multiple-pass 24-h dietary recall method on two different days. Anthropometric and BP measurement were taken using standard procedures, and BMI and WHR were calculated. Data analyses included descriptive statistics, ANOVA, and stepwise regression analyses. Using stepwise regression analysis, hip circumference (HC) predicted boys' systolic (S)BP (R(2) = 0.55). For girls' SBP, mid-upper arm circumference, WHR, low calcium consumption, and height percentile jointly explained 41% of the total variation. Mid upper arm circumference (MAC) and carbohydrate consumption predicted 35% of the variance for boys' diastolic (D)BP, and HC, dairy consumption, and calcium intake predicted 31% of the total variance for girls' DBP. Responses to dietary acculturation questions revealed between group differences for breakfast with half of the younger Born-Thailand/Laos (Born-T/L) consuming mostly Hmong food, while at dinner Born-US consumed a mixed diet and Born-T/L were more likely to consume Hmong food. Dietary acculturation and body composition predict Hmong children's BP. Copyright © 2012 Wiley Periodicals, Inc.

  8. Constructing a Governing Rationale: Developing Lao Hmong Refugees at Wat Tham Krabok

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available In this paper I argue that Thai discourses of modernization and development have been taken up by the leaders and other prominent monks at Wat Tham Krabok Buddhist Temple (WTK in central Thailand’s Saraburi Province and directed at governing a settlement of mostly Lao Hmong refugees that made their home on temple controlled land from the 1990s to 2000s. Though decoding the motivations on the part of WTK’s leaders and other senior monks for allowing thousands of Hmong to settle on WTK controlled land is a complex process, viewing the story through the lens of development teaches new things about their overarching motivations for such an intervention. Furthermore, it allows several aspects of their governing rationale—including attention to legibility, territoriality, infrastructural development—to stand out and reveals that WTK’s leaders enacted specific projects that appear to be directed at governing, reforming, and possibly modernizing the Hmong population at WTK. The styles of this intervention varied between the temples second and third abbots, Chamroon and Charoen, in their respective use of discursive versus material means of intervention. Considering these goals in concert with the history of material construction at the temple highlights how the material and discursive aspects of life at WTK are recursively connected to reinforce regimes of Hmong development toward an ideal of modernity that pays homage to symbols of Thai modernity and legitimizes WTK as a worthy Buddhist institution.

    2014-12-01

    Full Text Available Background: Over the past several decades in Northern Thailand, there has been a contest of authoritative knowledge between the Hmong traditional birth system and the Thai biomedical maternity system. In this paper, we explore the contest in one Hmong village by describing the traditional and biomedical practices; families’ birth location choices; and elements of authoritative knowledge. Methods: We built on a village survey and conducted an ethnographic qualitative case study of 16 families who made different pregnancy care choices. Results: The contest is being won by the Thai biomedical system, as most families deliver at the hospital. These families choose hospital births when they evaluate problems or potential problems; they have more confidence in the superior Thai biomedical system with its technology and medicines than in the inadequate Hmong traditional system. But the contest is ongoing, as some families prefer to birth at home. These families choose home births when they want a supportive home environment; they embrace traditional Hmong birth knowledge and practices as superior and reject hospital birth practices as unnecessary, harmful, abusive, and inadequate. Despite their choice for any given pregnancy, the case study families feel the pull of the other choice: hospital birth families lament loss of the home environment and express their dislike of hospital practices; and home birth families feel the anxiety of potentially needing quick obstetrical assistance that is far away. Conclusion: While most families choose to participate in the Thai biomedical system, they also use Hmong pregnancy and postpartum practices, and some families choose home births. In this village, the contest for the supremacy of authoritative birth knowledge is ongoing.

    2014-06-01

    The purpose of the study was to elicit the definitions of successful aging according to Chinese and Hmong elders living in Milwaukee, WI. In-depth semi-structured interviews were conducted with 44 elders (Hmong n = 21 and Chinese n = 23). Findings show some similarities in the Chinese and Hmong elders' definitions though specific cultural differences exist. Chinese elders emphasized physical health and mobility, mental health, positive attitudes, shedding responsibilities, positive family relationships, financial stability, social engagement, religious faith, and accomplishments and volunteer work. Hmong elders emphasized physical health and mobility, mental health, harmonious relationships, positive family relationships, tangible family support, financial stability, social engagement, and religious faith. Cross-cultural comparisons of the findings highlight the cultural heterogeneity between these two subgroups. Implications for practice are discussed.

    Full Text Available Although the Hmong have resided in the United States since the 1970s, there has been limited research exploring the effect of acculturation and stigma on the Hmong community and their perspective of mental health services. This study investigated the relationship between Hmong women’s level of acculturation, perception of stigma, and the expression of attitudes toward professional psychological help and willingness to see a counselor. The 222 Hmong women completed a Demographic Questionnaire Form (DQF, the Suinn-Lew Asian Self-Identity Acculturation Scale (SL-ASIA, then the Stigma for Receiving Psychological Help (SSRPH, the Attitudes Toward Seeking Professional Psychological Help-Short Form (SSRPH-SF, and finally, the Willingness to See a Counselor questionnaire (WSC. Almost 86% of the Hmong women were between 18 and 35 years old, and 96.4% lived in the United States for 20 or more years and almost 53% practice Shamanism. Data analysis of the research hypotheses found that there was a weak positive significant correlation between acculturation and willingness to seek services. Additionally, the relationship between acculturation and attitudes toward counseling services, expression of attitudes and perception of stigma was statistically significant. However, the relationships between the other study variables: perception of stigma and acculturation, expression of attitudes and acculturation, and acculturation and willingness were not statistically significant. The findings of this study will enhance our understanding of Hmong women and their views of counseling.

    Directory of Open Access Journals (Sweden)

    Kao-Ly Yang

    2007-01-01

    Full Text Available The purpose of this case study is to shed light on the identity of the spirit of fertility called Lady Kaying –Niam Nkauj Kab Yeeb—, its religious origin and the general processes of borrowing her fromother cultures within the Hmong culture. Hmong popular beliefs pertaining to Kaying reveal that Kaying is in fact the Chinese Goddess of Mercy Guanyin. She was imported from MahayanaBuddhism by the Hmong people of China who had retained her roles of the “Bestower of Children", the “Guardian Angel” or the "Conductor of the Dead Children". An analysis of the process of borrowing of the Chinese deity into the Hmong pantheon shows that Lady Kaying overlaps with an ancient spirit, the “Ancestor Spirit of Fertility” or Niam Poj Dab Pog. This case study demonstrates that the processes of borrowing are selective, integrative and comprehensive: some traits or fragments were taken from Buddhism and incorporated into the Hmong beliefs through a superimposing of a Hmong pre-existing system of beliefs.

  18. Views of Science Teaching and Learning by Immigrant Somali Elders: Perceptions of Conflict and Acceptance

    Science.gov (United States)

    Albrecht, Nancy Jean

    The gap between a student's home culture and that of classroom science may create challenges for students and families, especially those from recent immigrant cultures, including refugees. As a result, science learning in schools may require a form of cultural border crossing between home cultures and the culture of classroom science. Given this, as educators, how do we make these borders more porous for better science learning experiences? Using the frameworks of funds of knowledge, culturally relevant pedagogy, and socio-constructivism, this study focuses on the perspectives of Somali-American elders and parents about school science. Designed as an in-depth interview study, five purposefully selected participants were interviewed over a period of two years. The guiding questions for the study included: 1) What are the perceptions of Somali elders about school science? and 2) How do Somali elders believe science teaching and learning can facilitate Somali students' engagement in science?. Analysis of the interview data revealed that Somali-American adults have complicated perceptions of school science that include both conflicts and acceptance with current pedagogy and content. For example, science education was highly valued by both individuals and the Somali community, both as a way for individuals to attain economic prosperity and respect, but also as a way to lift up the Somali diaspora, both here and in their native homeland. On the other hand, science was also viewed as an abstract discipline with little connection to students' and families' everyday home lives. Moreover, due to the intrinsic role that Islam plays in traditional and contemporary Somali culture, several areas of science education, including geology, evolution and sex education, were viewed as problematic and unresolvable. Various potential areas of funds of knowledge and culturally relevant pedagogy were discussed including nutrition, food preparation and storage, health education, and

    Full Text Available Bee Vang, of Minneapolis, played the Hmong lead Thao Vang Lor in Clint Eastwood's 2008 Gran Torino. He was sixteen when he shot the film and had no acting training. For 27 days on location in urban Detroit he played before a Hollywood crew opposite an icon of the filmindustry doing multiple takes of each scene and camera angle. The shoot was full of unexpected twists and turns some of which he recounts in these interchanges with Hmong media expert Louisa Schein of the Departments of Anthropology and Women's and Gender Studies at Rutgers University. Over several conversations, condensed here, Vang and Schein talk about Gran Torino, about acting and film critique, about immigrants and stereotypes, about masculinity and sexuality, and about Vang's vision for what needs to change to address problems of race and inequality in and beyond media worlds.

    To investigate influences on shopping and eating behavior of Hmong adults living in St. Paul/Minneapolis, Minnesota. Conducted a mapping project, food surveys, food frequency questionnaire (FFQ), and focus groups (n = 11). Subjects were assigned to three groups. The B-TL(1) group was made up of subjects who were born in Thailand/Laos and had lived in the US 5 years (n = 20). The B-US group was made up of subjects who were born and/or raised in the US (n = 30). Using Geographical Informational Systems software, 15 grocery stores were mapped and surveyed. Food prices were compared with the consumer price index (CPI). The FFQ assessed food consumption patterns. Focus group transcripts were evaluated for themes and coded. Degree of acculturation was assessed by adapting a previously developed instrument. The population is concentrated in St. Paul, coinciding with store density. Limited foods had CPIs and some CPIs were outdated. B-US had significantly higher levels of dietary acculturation than B-TL(2) and B-TL(1), with B-TL(2) also having a higher dietary acculturation level compared with B-TL(1). Acculturation of the Hmong into the American food system, determinants of store type, and Hmong food's having a mainstream factor were identified themes. B-US and B-TL(2) shopped at American stores more than did B-TL(1) because of convenience, one-stop shopping, and increased English fluency. Hmong foods have entered the American food system and are sold at Asian and American stores.

    Full Text Available The need to decrease health disparities has been widely documented in the professional literature, therefore, it is not surprising that one of the two goals listed in Healthy People 2010 is the reduction of health disparities in ethnic and racial communities in the United States. The research literature, however, shows that the majority of efforts to decrease health disparities have focused on the major racial and ethnic groups in the United State and few if any efforts have focused on the healthcare needs, practices, beliefs, barriers, and other health aspects of the Hmong community. The purpose of this study is to record barriers to addressing diabetes in the Hmong community. Data were collected using Photovoice, a qualitative data collection method which enables participants to record in photo format the issues they experience. Findings from the study identified several barriers to diabetes prevention in the Hmong community. Participants indicate 1 the environment as a major key barrier, 2 personal choices, habits, and life style and, 3 lack of a safe environment to access physical activity as factors contributing to the potential for developing diabetes.

    The Hmong Diaspora is one of the widest modern human migrations. Mainly localised in South-East Asia, the United States of America, and metropolitan France, a small community has also settled the Amazonian forest of French Guiana. We have biologically analysed 62 individuals of this unique Guianese population through three complementary genetic markers: mitochondrial DNA (HVS-I/II and coding region SNPs), Y-chromosome (SNPs and STRs), and the Gm allotypic system. All genetic systems showed a high conservation of the Asian gene pool (Asian ancestry: mtDNA=100.0%; NRY=99.1%; Gm=96.6%), without a trace of founder effect. When compared across various Asian populations, the highest correlations were observed with Hmong-Mien groups still living in South-East Asia (Fst<0.05; P-value<0.05). Despite a long history punctuated by exodus, the French Guianese Hmong have maintained their original genetic diversity. Copyright © 2012 Académie des sciences. Published by Elsevier SAS.

    Refugees who resettle in a new country face numerous struggles, including overcoming past traumas and coping with post-migration stressors, such as lack of meaningful social roles, poverty, discrimination, lack of environmental mastery, and social isolation. Thus, in addition to needing to learn concrete language skills and gain access to resources and employment, it is important for refugees to become a part of settings where their experiences, knowledge, and identity are valued and validated. The Refugee Well-Being Project (RWBP) was developed to promote the well-being of Hmong refugees by creating settings for mutual learning to occur between Hmong adults and undergraduate students. The RWBP had two major components: (1) Learning Circles, which involved cultural exchange and one-on-one learning opportunities, and (2) an advocacy component, which involved undergraduates advocating for and transferring advocacy skills to Hmong families to increase their access to resources in their communities. The project was evaluated using a mixed quantitative and qualitative approach. This article discusses data from qualitative interviews with participants, during which the importance of reciprocal helping relationships and mutual learning emerged as significant themes.

    Full Text Available Mothers are viewed as the people who are raising future citizens of Canada; therefore, their parenting practices are being targeted for intervention by civic organizations funded by the state. In this article, I argue that modernity narratives and neoliberalism approaches to mothering inform parenting education classes for Somali refugee women to Canada. Thus, Somali women are often seen as victims. Stereotyped identities conceal their social and historical agency. This research draws on 15 individual interviews with Somali mothers and participant- observation in two parenting education classes in Canada.

    2015-12-01

    Full Text Available Following an overview of the Franco-Hmong relationship that developed during the first half of the twentieth century and laid the groundwork for future alignments, the main body of this paper focuses on the formative years of the multi-faceted Hmong-American alliance that evolved between 1949 and 1962. Chronologically summarized, this period encompasses wide-ranging and often tumultuous events that ultimately put Laos in what has been described as the cockpit of the Cold War and placed the Hmong on the front lines. When the colonial French withdrew from Laos following the First Indochina War, the United States stepped in to fill the vacuum left behind in the politically unstable country, Washington’s objective being to neutralize Laos and block Communist infiltration from North Vietnam through northeastern Laos—the homeland of the Hmong—and into the Mekong valley, the heartland of the politically dominant Lao, and neighboring Thailand. Trapped in the middle were the Hmong, a multi-clan ethnic minority originally from China that was held in contempt by the governing Lao. The Hmong resettled mainly in Xieng Khouang, a province bordering Tonkin in Vietnam, a country whose hegemony the Hmong historically resisted. The pro-West paramount leaders of the Hmong, Touby Lyfoung and his successor Vang Pao, served as mediators between clan leaders and were mindful of the expectations of their people and their aspiration for freedom. Recognizing that the threat posed by the Vietnamese placed their homeland and livelihoods in jeopardy, they negotiated the support of powerful foreign patrons—the French and later the Americans—and served as intermediaries between the Hmong clan leaders, their foreign patrons, and successive Lao governments. As the showdown leading to the so-called “Secret War” edged forward, the political agendas of the key players were frequently readjusted in the volatile environment. This paper describes the resulting

    To the authors' knowledge, there are few studies to date regarding colorectal cancer (CRC) beliefs, knowledge, and screening among multiple Asian American populations, who are reported to have lower CRC screening rates compared with white individuals. The current study was performed to assess knowledge and beliefs regarding the causes of CRC, its prevention, and factors associated with CRC screening among 3 Asian American groups. The authors conducted an in-language survey with Filipino (Honolulu, Hawaii), Hmong (Sacramento, California), and Korean (Los Angeles, California) Americans aged 50 to 75 years who were sampled through social networks. Bivariate and multivariable analyses were conducted to assess factors associated with CRC screening. The sample of 981 participants was 78.3% female and 73.8% reported limited proficiency in English. Few of the participants were aware that age (17.7%) or family history (36.3%) were risk factors for CRC; 6.2% believed fate caused CRC. Only 46.4% of participants knew that screening prevented CRC (74.3% of Filipino, 10.6% of Hmong, and 55.8% of Korean participants; PFilipino, 72.0% of Hmong, and 51.4% of Korean participants; PFilipino, 43.8% of Hmong, and 41.4% of Korean participants; PFilipino), having a family history of CRC, having health insurance or a regular source of health care, and knowing that a fatty diet caused CRC. Believing that fate caused CRC and that praying prevented it were found to be negatively associated with ever screening. Factors associated with being up to date for CRC screening included being born in the United States, having a family history of CRC, and having access to health care. Knowledge regarding the causes of CRC and its prevention among Filipino, Hmong, and Korean individuals is low. However, health care access, not knowledge or beliefs, was found to be a key determinant of CRC screening. Cancer 2018;124:1552-9. © 2018 American Cancer Society. © 2018 American Cancer Society.

    Knowledge of Somali immigrants' mental health care beliefs and practices is needed so that nurses can promote culturally congruent care. The purpose of this study was to explore, discover, and understand mental health meanings, beliefs, and practices from the perspective of immigrant Somalis. Leininger's qualitative ethnonursing research method was used. Thirty informants (9 key and 21 general) were interviewed in community settings. Leininger's ethnonursing enablers and four phases of analysis for qualitative data were used. Analysis of the interviews revealed 21 categories and nine patterns from which two main themes emerged. The themes are the following: (a) Our religion significantly influences our mental health and (b) Our tribe connectedness, cultural history, and khat usage are significant in mental health. Somali cultural and religious beliefs and practices influence their health care choices. The findings will improve care by promoting culturally congruent care for the Somali immigrant population. © The Author(s) 2014.

    This study examines the role of social identity (acculturation and gender) in moderating the association between discrimination and Somali adolescent refugees' mental health. Participants were English-speaking Somali adolescent refugees between the ages of 11 and 20 (N = 135). Perceived discrimination, trauma history, posttraumatic stress disorder (PTSD), depressive symptoms, and behavioral acculturation were assessed in structured interviews. Fourteen in-depth qualitative interviews and 3 focus groups were also conducted. Results indicated that discrimination was common and associated with worse mental health. For girls, greater Somali acculturation was associated with better mental health. Also, the association between discrimination and PTSD was less strong for girls who showed higher levels of Somali acculturation. For boys, greater American acculturation was associated with better mental health, and the association between discrimination and depression was less strong for boys with higher levels of American acculturation. © 2010 American Orthopsychiatric Association.

    Hmong Americans face high cancer mortality rates even in comparison to their Asian American counterparts, and report low utilization of cancer screenings. To date, no study has been conducted on the cultural barriers this population faces in undergoing cancer screenings. A systematic review of the literature was conducted to examine the existing knowledge regarding the barriers to cancer screening for Hmong Americans. Potential barriers were identified from this examination to include: health access factors (type of health insurance, ethnicity of provider, low English proficiency, and years spent in the U.S.); cultural factors (belief in the spiritual etiology of diseases, patriarchal values, modesty, and mistrust of the western medical system); and cancer literacy factors (cancer and prevention illiteracy). Based on this review, potential cultural and ethnic group-specific prevention strategies and cancer health policies are discussed to address these barriers and enhance screening behavior among the Hmong.

    Giving birth in a foreign country implies going through a life event with little or no access to your own traditions and social support. The aim of this study was to study the childbirth experiences of Somali women and men in Sweden. Qualitative. Nine women and seven men were interviewed. Data collection was characterised by an openness to new ideas during the interview and the interviews were analysed according to the grounded theory technique. The meeting of Somalis with Swedish antenatal and delivery care was a multicultural event. It revealed social, medical, cultural and gender factors advocating space in the arena of childbirth. The Somalis constituted a homogeneous group with regard to their cultural belonging and motives for exile. The subjects were heterogeneous in that they represented a great variety in social and demographic background as well as in experiences, feelings and modes of expression. One striking finding was the Somali man's dramatic entrance into childbirth, which seemed to have a strong impact on the Somali woman's well-being during delivery. The study showed difficulties in getting used to the Swedish model of parenthood and in finding new role divisions in the couple relationship. Some of the subjects had experienced a strengthening of their marriage and an increased understanding of each other. Others commented that various aspects of traditional womanhood and manhood were lost as a result of the unfamiliar gender structures in Sweden. The Somalis' experiences of childbirth in Sweden can be understood by using the theoretical concept of gender, rather than culture. Our own and other studies show that women and men may have different frames of reference in childbirth, where the women mainly focus on biological circumstances and the men on the social and cultural aspects of birth. The Somali couple were found to be vulnerably positioned, with the professionals having the important role of supporting and empowering Somali parents.

    The purpose of this study was to describe diabetes literacy among Somali immigrants with diabetes and its association with diabetes outcomes. Among Somali immigrants in North America, the prevalence of diabetes exceeds that of the general population, and their measures of diabetes control are suboptimal when compared with non-Somali patients. Diabetes literacy is an important mediator of diabetes outcomes in general populations that has not been previously described among Somali immigrants and refugees. Diabetes literacy was measured using a translated version of the spoken knowledge in low literacy in diabetes (SKILLD) scale among Somali immigrants and refugees with type 2 diabetes. Diabetes outcome measures, including hemoglobin A1C, low-density lipoprotein (LDL) cholesterol, and blood pressure, were obtained for each patient. Multivariate logistic regression was used to assess associations between diabetes literacy and diabetes outcomes. Among 50 Somali patients with diabetes who completed the survey, the mean SKILLD score was low (42.2 %). The diabetes outcome measures showed a mean hemoglobin A1C of 8 %, LDL cholesterol of 99.17 mg/dL (2.57 mmol/L), systolic blood pressure of 130.9 mmHg, and diastolic blood pressure of 70.2 mmHg. There was no association between diabetes literacy scores and diabetes outcome measures. Somali patients with diabetes mellitus had low diabetes literacy and suboptimal measures of diabetes disease control. However, we found no association between diabetes literacy and diabetes outcomes. Future work aimed at reduction of diabetes-related health disparities among Somali immigrants and refugees to high-income countries should go beyond traditional means of patient education for low-literacy populations.

    Full Text Available Abstract Background Screening rates for breast and cervical cancer for Muslim women in the United States are low, particularly for first-generation immigrants. Interpretations of the Muslim faith represent some of the barriers for breast and cervical cancer screening. Working to understand how faith influences breast and cervical screening for Somali women, and working with the community to identify and utilize faith-based assets for promoting screening, may lead to life-saving changes in screening behaviors. Methods We partnered with an Imam to develop faith-based messages addressing the concerns of modesty and predetermination and promoting cancer testing and screening. A total of five focus groups were convened, with 34 Somali women (three groups and 20 Somali men (two groups. Each focus group first discussed participant views of breast and cervical cancer screening in general and then viewed and discussed video clips of the Imam delivering the faith-based messages. Results Both Somali women and men had an overwhelmingly positive response to the faith-based messages promoting breast and cervical cancer screening. The faith-based messages appeared to reinforce the views of those who were already inclined to see screening positively, with participants describing increased confidence to engage in screening. For those who had reservations about screening, there was feedback that the faith-based messages had meaningfully influenced their views. Conclusions Somali immigrant women and men found faith-based messages addressing topics of predestination and modesty and encouraging the use of screening and treatment to be both acceptable and influential. Faith can play an important role as an asset to promote breast and cervical cancer screening, and there may be substantial benefits to adding faith-based messaging to other interventions that focus on improving screening uptake. This may help to address health disparities for Somali women in this area.

    Full Text Available The aim of this study was to determine the energy requirements for maintenance (NEm and growth of 48 Brazilian Somali ram lambs with an average initial body weight of 13.47±1.76 kg. Eight animals were slaughtered at the trials beginning as a reference group to estimate the initial empty body weight (EBW and body composition. The remaining animals were assigned to a randomised block design with eight replications per block and five diets with increasing metabolisable energy content (4.93, 8.65, 9.41, 10.12 and 11.24 MJ/kg dry matter. The logarithm of heat production was regressed against metabolisable energy intake (MEI, and the NEm (kJ/kg0.75 EBW/day were estimated by extrapolation, when MEI was set at zero. The NEm was 239.77 kJ/kg0.75 EBW/day. The animal’s energy and EBW fat contents increased from 11.20 MJ/kg and 208.54 g/kg to 13.54 MJ/kg and 274.95 g/kg of EBW, respectively, as the BW increased from 13 to 28.70 kg. The net energy requirements for EBW gain increased from 13.79 to 16.72 MJ/kg EBW gain for body weights of 13 and 28.70 kg. Our study indicated the net energy requirements for maintenance in Brazilian Somali lambs were similar to the values commonly recommended by the United States’ nutritional system, but lower than the values recommended by Agricultural Research Council and Commonwealth Scientific and Industrial Research Organization. Net requirements for weight gain were less compared to the values commonly recommended by nutritional system of the United States.

  15. Air-Sea Interaction in the Somali Current Region

    The western Indian Ocean is an area of high eddy-kinetic energy generated by local wind-stress curl, instability of boundary currents as well as Rossby waves from the west coast of India and the equatorial wave guide as they reflect off the African coast. The presence of meso-scale eddies and coastal upwelling during the Southwest Monsoon affects the air-sea interaction on those scales. The U.S. Navy's Coupled Ocean-Atmosphere Mesoscale Prediction System (COAMPS) is used to understand and quantify the surface flux, effects on surface waves and the role of Sea Surface Temperature anomalies on ocean-atmosphere coupling in that area. The COAMPS atmosphere model component with 9 km resolution is fully coupled to the Navy Coastal Ocean Model (NCOM) with 3.5 km resolution and the Simulating WAves Nearshore (SWAN) wave model with 10 km resolution. Data assimilation using a 3D-variational approach is included in hindcast runs performed daily since June 1, 2015. An interesting result is that a westward jet associated with downwelling equatorial Rossy waves initiated the reversal from the southward Somali Current found during the northeast monsoon to a northward flow in March 2016 more than a month before the beginning of the southwest monsoon. It is also found that warm SST anomalies in the Somali Current eddies, locally increase surface wind speed due to an increase in the atmospheric boundary layer height. This results in an increase in significant wave height and also an increase in heat flux to the atmosphere. Cold SST anomalies over upwelling filaments have the opposite impacts on air-sea fluxes.

    Full Text Available Protest is one political strategy by which marginalized groups can try to effect social change in society. As an ethnic group with a unique historical relationship with the United States government, Hmong former refugees have regularly engaged in protests in response to perceived political threats, political opportunities, or both. Using cataloged English-language newspapers, this study examines the characteristics, forms and collective action frames of 84 Hmong American-led protest events in the United States between 1980 and 2010. The evidence indicates that Hmong American protests emerged in the 1990s, coinciding with their formation of socioeconomically mobile ethnic communities, and continued to increase in frequency throughout the 2000s particularly in places with substantial concentrations of Hmong. Although most Hmong protest events involved demonstrations, these events varied greatly in terms of their targets and issues. During the past 30-35 years, Hmong American cycles of protest have produced three master frames: the refugee protection frame, the military service frame, and the civil rights frame. I argue that the military service frame represents one of the most enduring and, to date, most potent collective action frames in Hmong Americans’ modern repertoire of contention. Immigrant groups’ increasingly developed communities and their strategic use of collective action frames could have significant implications for their political incorporation in the United States.

    Full Text Available This paper comes from a three month period of fieldwork that I conducted in a green Hmong village in northern Thailand during the summer of 1998. During that time a crisis erupted between a local Thai government organization and the families of “Muban”1 in which one of my main informants, Ga, a 20 year old Hmong kindergarten teacher, played a major role. Although the conflict remained unresolved at the time I left Thailand, I believe that an analysis of the events, along with an analysis of Ga's role in the crisis, will illustrate the way in which education contributes to the production of new identities which social actors draw on to interpret ambiguous and contradictory social situations. I am not suggesting that Ga's project can ultimately be considered successful in effectively accomplishing such a transformation, but what I do believe her experience shows is the ways in which education, history and politics may impact the production and distribution of cultural meanings, which make such transformations possible. Moreover, the shifting identities members of a culture may craft out of different social discourses position them in and around such cultural meanings thus making it possible for them to pursue contradictory social aims within a cultural formation, and to possibly alter the way in which cultural resources are reproduced. After a brief introduction to the Hmong in northern Thailand and a discussion of some of the social reproduction theory as it has been considered within anthropology and more particularly educational anthropology, the paper will proceed to the crisis and its analysis.

    Participation in Human Papillomavirus (HPV) vaccination and Papanicolaou Screening (Pap smears) is low among ethnic minorities in the Netherlands and hardly any information is available about the cervical cancer prevention methods of Somali women living in the diaspora. This qualitative study, based on the Health Belief Model (HBM) and an intersectionality-based framework, explores the perceptions of Somali women living in the Netherlands regarding measures to prevent cervical cancer. Semi-structured interviews have been conducted with young Somali women aged 17-21 years (n = 14) and Somali mothers aged 30-46 years (n = 6). Two natural group discussions have been conducted with 12 and 14 Somali mothers aged 23-66 years. The collected data has been analyzed thematically for content. In this study, we have identified perceived barriers to the use of preventive measures across three major themes: (1) Somali women and preventive healthcare; (2) Language, knowledge, and negotiating decisions; and (3) Sexual standards, culture, and religion. Many issues have been identified across these themes, e.g., distrust of the Dutch health care system or being embarrassed to get Pap smears due to Female Genital Mutilation (FGM) and having a Dutch, male practitioner; or a perceived low susceptibility to HPV and cancer because of the religious norms that prohibit sex before marriage. Current measures in the Netherlands to prevent women from developing cervical cancer hardly reach Somali women because these women perceive these kinds of preventative measures as not personally relevant. Dutch education strategies about cervical cancer deviate from ways of exchanging information within the Somali community. Teachers can provide culturally sensitive information to young Somali women in schools. For Somali mothers, oral education (e.g., poetry or theater) about the Dutch health care system and men's roles in HPV transmission may be useful. An intersectional approach, grounded in

    Nonadherence to colorectal cancer (CRC) screening among Asian Americans is high but not well understood. This study examined correlates of screening intention among Filipino, Hmong, and Korean Americans who were nonadherent to CRC screening. Using cross-sectional, preintervention survey data from 504 Asian Americans (115 Filipinos, 185 Hmong, and 204 Koreans) aged 50-75 years who were enrolled in a multisite cluster randomized controlled trial of lay health educator intervention, we analyzed correlates of self-reported CRC screening nonadherence, which was defined as not being up-to-date for fecal occult blood test, sigmoidoscopy, or colonoscopy. Only 26.8% of participants indicated intention to obtain screening within 6 months (Hmong: 12.4%; Korean: 30.8%; and Filipino: 42.6%; P Filipinos, which was unexplained by socio-demographics, health care factors, perceived needs for CRC screening, or knowledge of screening guidelines. CRC screening intention among nonadherent Filipino, Hmong, and Korean Americans was low. Targeting knowledge of CRC screening guidelines may be effective strategies for increasing CRC screening intention among nonadherent Asian Americans.

    Physical inactivity presents a major public health challenge and is estimated to cause six to ten percent of the major non-communicable diseases. Studies show that immigrants, especially women, have an increased risk of non-communicable diseases compared to ethnic Swedes. Somali immigrant women have increased rates of overweight and obesity, low fitness levels and low levels of cardiorespiratory fitness compared to non-immigrant women. These findings suggest that Somali women are at increased risk of developing lifestyle-related diseases. Few studies explore determinants of physical activity among Somali women. The aim of this study was to explore Somali women's views and experiences of physical activity after migration to Sweden. A qualitative focused ethnographic approach was used in this study. Four focus groups were conducted with twenty-six Somali women ranging from 17 to 67 years of age. Focus group discussions were recorded, transcribed verbatim and analysed using qualitative content analysis. The analysis resulted in four main themes and ten categories: Life in Somalia and Life in Sweden, Understanding and enhancing health and Facilitators and barriers to physical activity. Great differences were seen between living in Somalia and in Sweden but also similarities such as finding time to manage housework, the family and the health of the woman. The extended family is non-existent in Sweden, making life more difficult. Health was considered a gift from God but living a healthy life was perceived as the responsibility of the individual. Misconceptions about enhancing health occurred depending on the woman's previous life experience and traditions. There was an awareness of the importance of physical activity among the participants but lack of knowledge of how to enhance activity on an individual basis. Enhancing factors to an active lifestyle were identified as being a safe and comfortable environment. Some barriers, such as climate, lack of motivation and time

    Full Text Available The Hmong are some of the newest refugees who have settled in the United States with population estimates around 300,000. Unfortunately research has shown many Hmong children are not as successful in their education as their peers. Parental involvement in education has consistently been shown to impact academic success and attendance in higher education programs. Little is known about Hmong parental involvement in their children’s education process. Therefore, this study was done to compare and contrast the general family characteristics, parenting methods, parental involvement philosophies, parental involvement experiences, and parental education expectations in Hmong families of high school seniors classified as either high academic achievers or low achievers. Students were classified into either higher or lower academic achievement groups based on their high school cumulative GPA. Five students were randomly selected for each group and a qualitative research interview method was used to interview the students and both of their parents (n=30. The findings showed the parents of the higher academic achieving students were younger, had higher levels of education, and had better relationships and trust with the students. Parents from both groups did not have any written rules for their children to follow at home, they mainly became involved in their children’s education during the elementary and middle school years, and they did not have any specific preference of an educational level, career, or school for their children after high school. Recommendations for ways Hmong families can be encouraged to participate more in education are made.

    To examine perceived social and cultural capitals associated with family eating practices among Hmong, Latino, and white mothers and fathers. Six focus groups composed of 52 Hmong, Latino, and white mothers and fathers of young children were conducted to examine parental perceptions of social and cultural capitals associated with eating practices. Whereas Hmong participants unanimously emphasized the healthfulness of their traditional food, Latino groups had divergent views on their traditional foods' healthfulness. Hmong parents highly valued their traditional foods whereas white and Latino mothers were more accepting of new foods from other cultures. Participants noted divergent views on gender roles in family eating practices and food culture preservation efforts. Identifying and promoting bonding and bridging of cultural assets for healthy dietary practices among different cultural groups may be important for developing successful nutrition education programs across ethnicities in the community.

    Westernized approaches to mental health care often place limited emphasis on refugees' own experiences and cultural explanations of symptoms and distress. In order to effectively assess community mental health needs and develop interventions grounded in local needs, mental health programs need to be informed by an understanding of cultural features of mental health, including cultural idioms of distress (CIDs). The current study aims to explore CIDs among Somali refugees displaced in Kenya to understand mental health needs in cultural context and serve the community in a culturally responsive and sensitive manner. This research was conducted as a two-phase qualitative study. First, key informant interviews with Somali mental health stakeholders generated a list of 7 common Somali CIDs: buufis, buqsanaan, welwel, murug, qaracan, jinn, and waali. Typologies of each CID were further explored through four focus group interviews with Somali community members. The findings from a template analysis revealed Somali lay beliefs on how trauma and daily stressors are experienced and discussed in the form of CIDs and how each term is utilized and understood in attributing symptoms to associated causes. This study highlights the need to incorporate colloquial terms in mental health assessment and to adopt a culturally relevant framework to encourage wider utilization of services and religious/spiritual support systems.

    Violence against women is associated with serious health problems, including adverse maternal and child health. Antenatal care (ANC) midwives are increasingly expected to implement the routine of identifying exposure to violence. An increase of Somali born refugee women in Sweden, their reported adverse childbearing health and possible links to violence pose a challenge to the Swedish maternity health care system. Thus, the aim was to explore ways ANC midwives in Sweden work with Somali born women and the questions of exposure to violence. Qualitative individual interviews with 17 midwives working with Somali-born women in nine ANC clinics in Sweden were analyzed using thematic analysis. The midwives strived to focus on the individual woman beyond ethnicity and cultural differences. In relation to the Somali born women, they navigated between different definitions of violence, ways of handling adversities in life and social contexts, guided by experience based knowledge and collegial support. Seldom was ongoing violence encountered. The Somali-born women's' strengths and contentment were highlighted, however, language skills were considered central for a Somali-born woman's access to rights and support in the Swedish society. Shared language, trustful relationships, patience, and networking were important aspects in the work with violence among Somali-born women. Focus on the individual woman and skills in inter-cultural communication increases possibilities of overcoming social distances. This enhances midwives' ability to identify Somali born woman's resources and needs regarding violence disclosure and support. Although routine use of professional interpretation is implemented, it might not fully provide nuances and social safety needed for violence disclosure. Thus, patience and trusting relationships are fundamental in work with violence among Somali born women. In collaboration with social networks and other health care and social work professions, the

    Little is known about the impacts of health literacy and English proficiency on the health status of Somali refugees. Data came from interviews in 2009-2011 of 411 adult Somali refugees recently resettled in Massachusetts. English proficiency, health literacy, and physical and mental health were measured using the Basic English Skills Test Plus, the Short Test of Health Literacy in Adults, and the Physical and Mental Component Summaries of the Short Form-12. Associations were analyzed using multiple linear regression. In adjusted analyses, higher English proficiency was associated with worse mental health in males. English proficiency was not associated with physical health. Health literacy was associated with neither physical nor mental health. Language proficiency may adversely affect the mental health of male Somali refugees, contrary to findings in other immigrant groups. Research on underlying mechanisms and opportunities to understand this relationship are needed.

    Somali refugees are resettling in large numbers in the US, but little is known about the Somali Bantu, an ethnic minority within this population. Refugee youth mental health is linked to the functioning of the larger family unit. Understanding how the process of culturally adjusting to life after resettlement relates to family functioning can help identify what kind of interventions might strengthen families and lead to better mental health outcomes for youth. This paper seeks to address the following research questions: (1) How do different groups of Somali Bantu refugees describe their experiences of culturally adapting to life in the US?; and (2) How, if at all, do processes of cultural adaptation in a new country affect Somali Bantu family functioning? We conducted 14 focus groups with a total of 81 Somali Bantu refugees in New England. Authors analyzed focus groups using principles of thematic analysis to develop codes and an overarching theoretical model about the relationship between cultural adaptation, parent-child relationships, and family functioning. Views and expectations of parent-child relationships were compared between Somali Bantu youth and adults. Cultural negotiation was dependent upon broader sociocultural contexts in the United States that were most salient to the experience of the individual. Adult and youth participants had conflicting views around negotiating Somali Bantu culture, which often led to strained parent-child relationships. In contrast, youth sibling relationships were strengthened, as they turned to each other for support in navigating the process of cultural adaptation.

    Despite the high prevalence of type 2 diabetes in some immigrant and refugee communities in Norway, there is very little information available on their utilization of diabetes prevention interventions, particularly for women from Somali immigrant communities. A qualitative study of 30 Somali immigrant women aged 25 years and over was carried out in the Oslo area. Unstructured interviews were used to explore women's knowledge of diabetes, their access to preventive health facilities, and factors impeding their reception of preventive health programs targeted for the prevention of type 2 diabetes. The study participants were found to have a good knowledge of diabetes. They knew that a sedentary lifestyle and unhealthy diet are among the risk factors for diabetes. Regardless of their knowledge, participants reported a sedentary lifestyle accompanied with the consumption of an unhealthy diet. This was attributed to a lack of access to tailored physical activity services and poor access to health information. Considering gender-exclusive training facilities for Somali immigrant women and others with similar needs, in addition to access to tailored health information on diet, may encourage Somali women to adopt a healthy lifestyle, and it will definitely contribute to a national strategy for the prevention of diabetes.

    Full Text Available Somali youth, "the generation in-between", who arrived in Finland in their early teens or as teenagers in the 1990shave faced specific challenges in Somali diaspora in Finland. Their voice is often ambiguous in the processes of cultural construction and ethnic reconstruction. Dissonant acculturation and role reversal within the families and a family culture that emphasizes strong parental authority place these young people in a liminal position. Measures which balance the pace of the acculturation between the generations could alleviate the situation In addition, the diasporic consciousness and transnational activities among Somalis along with the ethos of 'integration' within the mainstream institutions challenge Somali youth. They may find themselves 'betwixt and between' various future orientations. This should be acknowledged in educational planning, for example. While liminal states may open up new opportunities, it is claimed that several simultaneous states of liminality may be confusing for a young person, and may create risks for becoming marginal from societal and cultural classifications, as well as limit a person from finding his/her own group of reference.

    Existing studies report a positive association between inadequate health literacy and immigrant's adverse health outcomes. Despite substantial research on this topic among immigrants, little is known about the level of health literacy among Somali women in Europe, and particularly in Norway. A cross sectional study using respondent driven sampling was conducted in Oslo, Norway. A sample of 302 Somali women, 25 years and older, was interviewed using the short version of the European Health Literacy Questionnaire. Data was analysed using logistic regression. Findings revealed that 71 % of Somali women in Oslo lack the ability to obtain, understand and act upon health information and services, and to make appropriate health decisions. Being unemployed (OR 3.66, CI 1.08-12.3) and socially less integrated (OR 8.17, CI 1.21-54.8) were independent predictors of an inadequate health literacy among Somali women. Enhanced health literacy will most likely increase the chance to better health outcomes for immigrants, thereby moving towards health equity in the Norwegian society. Therefore, policies and programs are required to focus and improve health literacy of immigrant communities.

    2015-01-01

    Full Text Available Despite the high prevalence of type 2 diabetes in some immigrant and refugee communities in Norway, there is very little information available on their utilization of diabetes prevention interventions, particularly for women from Somali immigrant communities. A qualitative study of 30 Somali immigrant women aged 25 years and over was carried out in the Oslo area. Unstructured interviews were used to explore women’s knowledge of diabetes, their access to preventive health facilities, and factors impeding their reception of preventive health programs targeted for the prevention of type 2 diabetes. The study participants were found to have a good knowledge of diabetes. They knew that a sedentary lifestyle and unhealthy diet are among the risk factors for diabetes. Regardless of their knowledge, participants reported a sedentary lifestyle accompanied with the consumption of an unhealthy diet. This was attributed to a lack of access to tailored physical activity services and poor access to health information. Considering gender-exclusive training facilities for Somali immigrant women and others with similar needs, in addition to access to tailored health information on diet, may encourage Somali women to adopt a healthy lifestyle, and it will definitely contribute to a national strategy for the prevention of diabetes.

  6. Adiposity and height of adult Hmong refugees: relationship with war-related early malnutrition and later migration.

    Clarkin, Patrick F

    2008-01-01

    This study investigated whether historical proxies for poor nutrition early in life were associated with differences in body composition and height among adult Hmong refugees. Life history and anthropometric data were collected from a sample of 279 Hmong aged 18-51 years who were born in Laos or Thailand and resettled in French Guiana or the United States following the Second Indochina War. Overall, 30.5% were born in a war zone in Laos, while 38.8% were displaced as infants; these individuals were presumed to have experienced malnutrition in the perinatal and infant periods, respectively. Resettlement in urban areas in the US was utilized as a proxy for greater exposure to excessive energy balance, compared with Hmong who resettled in rural areas in French Guiana. In multiple linear regression models, being displaced in infancy was negatively associated with height after controlling for confounders, while being born in a war zone was associated with higher adiposity and centralized body fat distribution. Resettlement in the US was associated with a higher centralization of subcutaneous fat, but not overall adiposity. These findings may be of interest to the study of the developmental origins of obesity, in a population that has undergone early malnutrition followed by migration and rapid nutritional transition.

    This study aimed to survey the prevalence, patterns of antibiotic resistance, and clinical factors associated with antibiotic resistance in Helicobacter pylori among the Karen and Hmong mountain people of Thailand. We recruited dyspeptic patients in the Maesod district, Tak Province, Thailand. All subjects underwent upper gastrointestinal endoscopy, and three antral gastric biopsies were obtained for rapid urease tests and culture. An epsilometer was used to determine the minimum inhibitory concentrations of amoxicillin (AMX), clarithromycin (CLR), metronidazole (MNZ), levofloxacin (LVX), ciprofloxacin (CIP), and tetracycline (TET). A total of 291 subjects were enrolled; 149 (51.2%) were infected with H. pylori. Helicobacter pylori infection was present in 47.1% of Thai, 51.7% of Karen, and 58.7% of Hmong subjects. Antibiotic resistance was present in 75.8% including AMX (0.8%), TET (0%), CLR (5.6%), MNZ (71.8%), CIP (19.4%), LVX (19.4%), and multidrug resistance in 21.8%. Karen subjects had the highest prevalence of MNZ resistance (84.6%), and Hmong subjects had the highest prevalence of fluoroquinolone (27.3%) and multidrug (34.1%) resistance. MNZ plus fluoroquinolone (14.5%) was the most common multidrug resistance. There was no association between clinical factors and antibiotic resistance. MNZ resistance was prevalent, whereas fluoroquinolone- and multidrug-resistant H. pylori infections are important problems in mountain people of Thailand. © The American Society of Tropical Medicine and Hygiene.

  8. Winter monsoon circulation of the northern Arabian Sea and Somali Current

    2000-03-01

    The winter monsoon circulation in the northern inflow region of the Somali Current is discussed on the basis of an array of moored acoustic Doppler current profiler and current meter stations deployed during 1995-1996 and a ship survey carried out in January 1998. It is found that the westward inflow into the Somali Current regime occurs essentially south of 11°N and that this inflow bifurcates at the Somali coast, with the southward branch supplying the equatorward Somali Current and the northward one returning into the northwestern Arabian Sea. This northward branch partially supplies a shallow outflow through the Socotra Passage between the African continent and the banks of Socotra and partially feeds into eastward recirculation directly along the southern slopes of Socotra. Underneath this shallow surface flow, southwestward undercurrent flows are observed. Undercurrent inflow from the Gulf of Aden through the Socotra Passage occurs between 100 and 1000 m, with its current core at 700-800 m, and is clearly marked by the Red Sea Water (RSW) salinity maximum. The observations suggest that the maximum RSW inflow out of the Gulf of Aden occurs during the winter monsoon season and uses the Socotra Passage as its main route into the Indian Ocean. Westward undercurrent inflow into the Somali Current regime is also observed south of Socotra, but this flow lacks the RSW salinity maximum. Off the Arabian peninsula, eastward boundary flow is observed in the upper 800 m with a compensating westward flow to the south. The observed circulation pattern is qualitatively compared with recent high-resolution numerical model studies and is found to be in basic agreement.

    We evaluated the consumption of healthy foods among Russian, Somali and Kurdish immigrants in Finland, and examined the relationship between socio-demographic factors and food consumption. We used data from the Migrant Health and Wellbeing Study (Maamu), a population-based health interview and examination survey in six different municipalities in Finland between 2010 and 2012. Altogether, 635 men and 737 women, aged 18-64 years, of Russian ( n = 527), Somali ( n = 337) and Kurdish ( n = 508) origin were included. The important socio-demographic determinants of healthy food consumption - sex, age, education, place of residence and household size - were assessed by logistic regression. Based on the consumption frequencies of recommended healthy foods - fruits, berries, vegetables, fish and rye bread - immigrants of Russian origin had higher consumption of healthy foods than their peers of Kurdish and Somali origin. Low consumption of fresh vegetables, fruits and berries was found among Somali immigrants. Sex and age were the most important determinants of healthy food consumption, as women and older age groups had diets closer to the national nutrition recommendations. High educational level was also positively associated with healthy food consumption. We found ethnic differences in the consumption of healthy foods among the immigrant groups of Russian, Somali and Kurdish origin in Finland. Socio-demographic factors, especially age, sex and education, seem to also play an important role in immigrants' food consumption. Further studies examining the consumption of fruits, berries and fresh vegetables among Somali immigrants in Finland are needed.

    We investigated the sexual values, attitudes, and behaviors of 30 Somali female refugees living in a large metropolitan area of Minnesota by collecting exploratory sexual health information based on the components of the sexual health model-components posited to be essential aspects of healthy human sexuality. A Somali-born bilingual interviewer conducted the semistructured interviews in English or Somali; 22 participants chose to be interviewed in Somali. Interviews were translated, transcribed, and analyzed using descriptive statistics and thematic analyses. Our study findings highlighted a sexually conservative culture that values sexual intimacy, female and male sexual pleasure, and privacy in marriage; vaginal sexual intercourse as the only sanctioned sexual behavior; and the importance of Islamic religion in guiding sexual practices. Findings related to human immunodeficiency virus (HIV) revealed HIV testing at immigration, mixed attitudes toward condom use, and moderate knowledge about HIV transmission modes. Female genital cutting (FGC) was a pervasive factor affecting sexual functioning in Somali women, with attitudes about the controversial practice in transition. We recommend that health professionals take the initiative to discuss sexual health care and safer sex, sexual behaviors/functioning, and likely challenges to sexual health with Somali women--as they may be unlikely to broach these subjects without permission and considerable encouragement.

    How do Hmong immigrant adolescent girls’ decide to run away, return home, leave again, or stay home? Video diaries by 11 sexually-exploited runaway Hmong girls, age 13–16, revealed four themes: “Fighting restrictions,” resisting family cultural expectations and desires to be like other American teens; “Not Running Away, Going Out to Play,” which captured impulsive decision-making; “Unrestrained Partying” described runaway experiences but minimized dangers they faced; and “Trying to Change,” returning home because of family bonds and wanting to “be someone good.” Given their limited ability to anticipate risks, interventions should focus on runaway prevention initiatives for Hmong families and teens.

    Thailand has high rates of maternity services; both antenatal care (ANC) and hospital delivery are widely used by its citizens. A recent Northern Thailand survey showed that Hmong women used maternity services at lower rates. Our objectives were to identify Hmong families' socio-cultural reasons for using and not using maternity services, and suggest ways to improve Hmong women's use of maternity services. In one Hmong village, we classified all 98 pregnancies in the previous 5 years into four categories: no ANC/home birth, ANC/home, no ANC/hospital, ANC/hospital. We conducted life-history case studies of 4 women from each category plus their 12 husbands, and 17 elders. We used grounded theory to guide qualitative analysis. Families not using maternity services considered pregnancy a normal process that only needed traditional home support. In addition, they disliked institutional processes that interfered with cultural birth practices, distrusted discriminatory personnel, and detested invasive, involuntary hospital procedures. Families using services perceived physical needs or potential delivery risks that could benefit from obstetrical assistance not available at home. While they disliked aspects of hospital births, they tolerated these conditions for access to obstetrical care they might need. Families also considered cost, travel distance, and time as structural issues. The families ultimately balanced their fear of delivering at home with their fear of delivering at the hospital. Providing health education about pregnancy risks, and changing healthcare practices to accommodate Hmong people's desires for culturally-appropriate family-centered care, which are consistent with evidence-based obstetrics, might improve Hmong women's use of maternity services.

    Full Text Available Abstract Background In Somalia, a large number of active and former combatants are affected by psychological problems such as Posttraumatic Stress Disorder (PTSD. This disorder impairs their ability to re-integrate into civilian life. However, many screening instruments for Posttraumatic Stress Disorder used in post-conflict settings have limited validity. Here we report on development and validation of a screening tool for PTSD in Somali language with a sample of ex-combatants. Methods We adapted the Posttraumatic Diagnostic Scale (PDS to reflect linguistic and cultural differences within the Somali community so that local interviewers could be trained to administer the scale. For validation purposes, a randomly selected group of 135 Somali ex-combatants was screened by trained local interviewers; 64 of them were then re-assessed by trained clinical psychologists using the Composite International Diagnostic Interview (CIDI and the Self-Report Questionnaire (SRQ-20. Results The screening instrument showed good internal consistency (Cronbach's α = .86, convergent validity with the CIDI (sensitivity = .90; specificity = .90 as well as concurrent validity: positive cases showed higher SRQ-20 scores, higher prevalence of psychotic symptoms, and higher levels of intake of the local stimulant drug khat. Compared to a single cut-off score, the multi-criteria scoring, in keeping with the DSM-IV, produced more diagnostic specificity. Conclusion The results provide evidence that our screening instrument is a reliable and valid method to detect PTSD among Somali ex-combatants. A future Disarmament, Demobilization and Reintegration Program in Somalia is recommended to screen for PTSD in order to identify ex-combatants with special psycho-social needs.

    Female circumcision (FC) has lifelong adverse social and health consequences for women, and its abolition will not only enhance the health of children and women, but also promote gender equality. Like many other Western countries, Norway hosts a large proportion of immigrants from FC-practicing countries, though primarily from Somalia, which is the country with the highest prevalence of FC in the world. A behavioral change by the practicing communities has the best chance to successfully and sustainably eliminate this practice. However, FC prevention programs require a behavioral surveillance that monitors the process of change, with this being the first quantitative study since the major migration of the Somali community to Norway began in 1991 to investigate whether or not Somali immigrants' attitudes toward the practice has improved in favor of its abandonment. A cross-sectional study using a respondent-driven sampling (RDS) was conducted in Oslo from April to June of 2011. A sample of 214 persons was interviewed, using structured questionnaires. The results show that 70% of Somalis in Oslo support the discontinuation of all forms of FC compared to 30% who support its continuation, with the latter group more likely to be people who lived in Norway ≤ 4 years. Of the 10 girls who came to Norway at the age of ≤ 7 years, only one was circumcised, though whether the circumcision occurred before or after the girl's arrival in Norway remains unclear. The perception that FC is required by religion was the sole factor to be significantly associated with an ongoing support of FC. The study reveals that Somalis in Oslo demonstrate a trend to abandon this practice over time. Nevertheless, the 30% of the people who still support its continuation, and who are primarily newly arrived immigrants, require a targeted intervention that is implemented in the early phase of the immigrants' arrival.

    To refine and validate an existing home food inventory (HFI) for low-income Somali- and Spanish-speaking families. Formative assessment was conducted using two focus groups, followed by revisions of the HFI, translation of written materials and instrument validation in participants’ homes. Twin Cities Metropolitan Area, Minnesota, USA. Thirty low-income families with children of pre-school age (fifteen Spanish-speaking; fifteen Somali-speaking) completed the HFI simultaneously with, but independently of, a trained staff member. Analysis consisted of calculation of both item-specific and average food group kappa coefficients, specificity, sensitivity and Spearman’s correlation between participants’ and staff scores as a means of assessing criterion validity of individual items, food categories and the obesogenic score. The formative assessment revealed the need for few changes/additions for food items typically found in Spanish-speaking households. Somali-speaking participants requested few additions, but many deletions, including frozen processed food items, non-perishable produce and many sweets as they were not typical food items kept in the home. Generally, all validity indices were within an acceptable range, with the exception of values associated with items such as ‘whole wheat bread’ (k = 0.16). The obesogenic score (presence of high-fat, high-energy foods) had high criterion validity with k = 0.57, sensitivity = 91.8%, specificity = 70.6% and Spearman correlation = 0.78. The revised HFI is a valid assessment tool for use among Spanish and Somali households. This instrument refinement and validation process can be replicated with other population groups.

    The discourse about mental health problems among migrants and refugees tends to focus on adverse pre-migration experiences; there is less investigation of the environmental conditions in which refugee migrants live, and the contrasts between these situations in different countries. This cross-national study of two samples of Somali refugees living in London (UK) and Minneapolis, Minnesota, (USA) helps to fill a gap in the literature, and is unusual in being able to compare information collected in the same way in two cities in different countries. There were two parts to the study, focus groups to gather in-depth qualitative data and a survey of health status and quantifiable demographic and material factors. Three of the focus groups involved nineteen Somali professionals and five groups included twenty-eight lay Somalis who were living in London and Minneapolis. The quantitative survey was done with 189 Somali respondents, also living in London and Minneapolis. We used the MINI International Neuropsychiatric Interview (MINI) to assess ICD-10 and DSM-IV mental disorders. The overall qualitative and quantitative results suggested that challenges to masculinity, thwarted aspirations, devalued refugee identity, unemployment, legal uncertainties and longer duration of stay in the host country account for poor psychological well-being and psychiatric disorders among this group. The use of a mixed-methods approach in this international study was essential since the quantitative and qualitative data provide different layers and depth of meaning and complement each other to provide a fuller picture of complex and multi-faceted life situations of refugees and asylum seekers. The comparison between the UK and US suggests that greater flexibility of access to labour markets for this refugee group might help to promote opportunities for better integration and mental well-being.

    Full Text Available Across-sectional questionnaire survey and focused group discussions were conducted to characterize camel production systems and to evaluate reproductive performances of camels at their natural pastoralist management systems of Somali region. A total of 100 households were included in the study during the period of October 2012 to March 2013. About 98% of Somali pastoralists preferred camels as their first choice over other livestock species and mainly kept in the society for milk and meat production. The camel management dominating in the study areas of Somali region is traditional nomadic. Camel is one of the most important livestock for Somali pastoralists’ livelihood as a source of milk, meat and draught power. Mature female camels were dominant (54.87% in the camel herd. The ratio of male to female camel was 1:13. Mean age at first calving and calving interval were 62.16±10.44 and 23.28±3.36 months respectively. Age at first calving and calving interval can be minimized to 57±5.52 and 21.84±4.8 months by proper husbandry and health care. The mean lactation length was 11.51±1.91 months. Diseases and predators were reported as the main causes of calf mortality. In the herd dynamic simulation calf mortality rate can be reduced at least to 7% only by preventing predators attack. Diseases (66%, lack of pasture (59% and security (47% were the main constraints in camel production of the study areas. For the better productivity of camels, the major constraints such as disease problems, lack of pasture and tribal conflicts should be mitigated. Proper husbandry and health services can play significant roles in the long term improvement of camel production and productivity of the region.

Results The results show that 70% of Somalis in Oslo support the discontinuation of all forms of FC compared to 30% who support its continuation, with the latter group more likely to be people who lived in Norway ≤ 4 years. Of the 10 girls who came to Norway at the age of ≤ 7 years, only one was circumcised, though whether the circumcision occurred before or after the girl’s arrival in Norway remains unclear. The perception that FC is required by religion was the sole factor to be significantly associated with an ongoing support of FC. Conclusion The study reveals that Somalis in Oslo demonstrate a trend to abandon this practice over time. Nevertheless, the 30% of the people who still support its continuation, and who are primarily newly arrived immigrants, require a targeted intervention that is implemented in the early phase of the immigrants’ arrival.

    Full Text Available In East-African and Arab countries, khat leaves are traditionally chewed in social settings. They contain the amphetamine-like alkaloid cathinone. Especially among Somali refugees khat use has been associated with psychiatric symptoms. We assessed khat use patterns and psychiatric symptoms among male Somali refugees living in a disadvantaged urban settlement area in Kenya, a large group that has not yet received scientific attention. We wanted to explore consume patterns and study the associations between khat use, traumatic experiences and psychotic symptoms.Using privileged access sampling we recruited 33 healthy male khat chewers and 15 comparable non-chewers. Based on extensive preparatory work, we assessed khat use, khat dependence according to DSM-IV, traumatic experiences, Posttraumatic Stress Disorder and psychotic symptoms using standardized diagnostic instruments that had been adapted to the Somali language and culture.Hazardous use patterns like chewing for more than 24 hours without interruption were frequently reported. All khat users fulfilled the DSM-IV-criteria for dependence and eighty-five percent reported functional khat-use, i.e. that khat helps them to forget painful experiences. We found that the studied group was heavily burdened by traumatic events and posttraumatic symptoms. Khat users had experienced more traumatic events and had more often PTSD than non-users. Most khat users experience khat-related psychotic symptoms and in a quarter of them we found true psychotic symptoms. In contrast, among control group members no psychotic symptoms could be detected.We found first evidence for the existence and high prevalence of severely hazardous use patterns, comorbid psychiatric symptoms and khat use as a self-medication of trauma-consequences among male Somali refugees in urban Kenyan refugee settlements. There is a high burden by psychopathology and adequate community-based interventions urgently need to be developed.

    Full Text Available After the defeat of the United States in Laos in 1975, the Hmong’s resettlement in Argentina during their diaspora from refugee camps in Thailand is a topic that has yet to be fully studied. At the moment of their arrival, the Argentine political and historical context, that is, the military regime during the Dirty War (1976-1983, which was internationally condemned for thousands of cases of violation of human rights, and the Centenary Celebrations of the Conquest of the Desert (1878-1885, when the indigenous population was destroyed under the Europeanization plan of the government, specifically influenced the situation of the newcomers. One of these Argentinian ethnic peoples was the Rankülche who display surprising similarities with the Hmong. This coincidence has suggested a novel perspective from which to study the presence of refugees from Southeast Asia through a comparative study with the Argentine native group, who once occupied the land allocated for the newcomers a century later. In spite of a huge geographical gulf, both ethnic groups share geopolitical and cultural commonalities. They were also considered by the central governments, in Argentina, Thailand and nearby countries, as the ‘other’ in their ‘marginal’ land and, thus, constituted a ‘problem’ of national security that have resulted in them facing different destinies in the nineteenth and twentieth centuries, respectively.

  7. The role of potential vorticity anomalies in the Somali Jet on Indian Summer Monsoon Intraseasonal Variability

    The climate of the Indian subcontinent is dominated by rainfall arising from the Indian summer monsoon (ISM) during June to September. Intraseasonal variability during the monsoon is characterized by periods of heavy rainfall interspersed by drier periods, known as active and break events respectively. Understanding and predicting such events is of vital importance for forecasting human impacts such as water resources. The Somali Jet is a key regional feature of the monsoon circulation. In the present study, we find that the spatial structure of Somali Jet potential vorticity (PV) anomalies varies considerably during active and break periods. Analysis of these anomalies shows a mechanism whereby sea surface temperature (SST) anomalies propagate north/northwestwards through the Arabian Sea, caused by a positive feedback loop joining anomalies in SST, convection, modification of PV by diabatic heating and mixing in the atmospheric boundary layer, wind-stress curl, and ocean upwelling processes. The feedback mechanism is consistent with observed variability in the coupled ocean-atmosphere system on timescales of approximately 20 days. This research suggests that better understanding and prediction of monsoon intraseasonal variability in the South Asian monsoon may be gained by analysis of the day-to-day dynamical evolution of PV in the Somali Jet.

    Genetic data from extant donkeys (Equus asinus) have revealed two distinct mitochondrial DNA haplogroups, suggestive of two separate domestication events in northeast Africa about 5000 years ago. Without distinct phylogeographic structure in domestic donkey haplogroups and with little information on the genetic makeup of the ancestral African wild ass, however, it has been difficult to identify wild ancestors and geographical origins for the domestic mitochondrial clades. Our analysis of ancient archaeological and historic museum samples provides the first genetic information on the historic Nubian wild ass (Equus africanus africanus), Somali wild ass (Equus africanus somaliensis) and ancient donkey. The results demonstrate that the Nubian wild ass was an ancestor of the first donkey haplogroup. In contrast, the Somali wild ass has considerable mitochondrial divergence from the Nubian wild ass and domestic donkeys. These findings resolve the long-standing issue of the role of the Nubian wild ass in the domestication of the donkey, but raise new questions regarding the second ancestor for the donkey. Our results illustrate the complexity of animal domestication, and have conservation implications for critically endangered Nubian and Somali wild ass.

By using a bold comparative approach and an ambitious tone of enquiry he places the traumatic Dutch Srebrenica experience in the context of two broadly similar processes of finger-pointing and evading responsibility in Canada and Belgium following their respective interventions in Somalia and Rwanda. He thus exposes many fascinating parallels, yet the historian Klep pays little attention to the differences between his case studies. This is regrettable, as this would have strengthened rather than weakened his otherwise compelling argument. The Somali case in particular differs from ‘Srebrenica’ and ‘Rwanda’, since the murders perpetrated by Canadian soldiers – horrific as they may have been – and the subsequent cover-up in no way constituted a defining moment in the collapsing international mission as a whole. Unlike the genocides in Rwanda and Srebrenica the death of the two Somalis was the result of a purely national Canadian failure, which helps explain why the Somalia Inquiry could identify guilty compatriots far more decisively than, for example, the Netherlands Institute for War Documentation (NIOD in its Srebrenica report.

    Full Text Available Approximately 5,000 to 6,000 Somalis arrived in Finland between 1990 and 1995 through Russia. Currently, 8,096 have settled permanently in the country. The data reported here is from a 1998-1999 research survey carried out in the Finish cities of Helsinki and Turku. The survey of 117 married Somalis explored the social-cultural determinants of contraception use. The paper presented here focuses upon one particular aspect of the survey. We selected 21 Somali parents (11 women and 10 men to look in-depth at the experiences of Somali migrants raising children in Finland. All of the respondents selected have more than 5 children in their family and all were asked to describe their experiences of raising children in Finland and, more generally, in establishing and maintaining family structures. Unlike their experiences in Somali, bringing up large families (by Westerns standards is not a collective matter in Finland where biological parents are left to manage the family for themselves. A number of challenges also accompany this shift in family norms: first, and most notably, there is the need to re-establish control over one's life in an alien environment; second, intergenerational conflict between adult migrants and their adolescent children is often heightened. The findings indicate that Somalis' experiences of raising children in Finland raise important parenting challenges associated with changing generational, gender and family relations within the migrant household. Importantly, this case study of large Somali families shows how migrants' lives are intricately linked to the household dynamic between home and host country. URN: urn:nbn:de:0114-fqs060388

    To assess attitudes towards and perceptions about contraceptive use among married refugee women of Somali descent living in Finland. A sample of 100 married refugee women of Somali descent (18-50 years of age) were invited to participate in a study on contraceptive use in Finland (30 women refused). Qualitative and quantitative methods were used to collect the data. Questionnaire of the first data set was written in the Somali language. Interviews were conducted in the Somali language. The attitudes and opinions of these women towards contraceptive use (73% did not use contraceptives, 27% did use them) were connected with religious beliefs and issues involving marital relations. Religious or gender issues did not seem to influence those who used contraception. The findings indicated that the majority of the married refugee women of Somali descent living in Finland did not use contraception. The process of starting the use of contraception was possible because of an access to good reproductive health care and family planning services, changes in life situations, and adaptations to Finnish social and cultural norms.

    Full Text Available Abstract Background The aim of this study was to establish the prevalence of posttraumatic stress disorder (PTSD and depression among Rwandese and Somali refugees resident in a Ugandan refugee settlement, as a measure of the mental health consequences of armed conflict, as well as to inform a subsequent mental health outreach program. The study population comprised a sample from 14400 (n = 519 Somali and n = 906 Rwandese refugees resident in Nakivale refugee settlement in South Western Uganda during the year 2003. Methods The Posttraumatic Diagnostic Scale (PDS and the Hopkins Symptom Checklist 25 were used to screen for posttraumatic stress disorder and depression. Results Thirty two percent of the Rwandese and 48.1% of the Somali refugees were found to suffer from PTSD. The Somalis refugees had a mean of 11.95 (SD = 6.17 separate traumatic event types while the Rwandese had 8.86 (SD = 5.05. The Somalis scored a mean sum score of 21.17 (SD = 16.19 on the PDS while the Rwandese had a mean sum score of 10.05 (SD = 9.7. Conclusion Mental health consequences of conflict remain long after the events are over, and therefore mental health intervention is as urgent for post-conflict migrant populations as physical health and other emergency interventions. A mental health outreach program was initiated based on this study.

    PDAC (also termed Matthew Wood) syndrome is a rare, autosomal recessive disorder characterized by pulmonary hypoplasia/aplasia, diaphragmatic defects, bilateral anophthalmia, and cardiac malformations. The disorder is caused by mutations in STRA6, an important regulator of vitamin A and retinoic acid metabolism. We describe six cases from four families of Hmong ancestry, seen over a 30 years period in California. These include: (i) consanguineous siblings with a combination of bilateral anophthalmia, diaphragmatic abnormalities, truncus arteriosus, and/or pulmonary agenesis/hypoplasia; (ii) a singleton fetus with bilateral anophthalmia, pulmonary agenesis, cardiac malformation, and renal hypoplasia; (iii) a sibling pair with a combination of antenatal contractures, camptodactyly, fused palpebral fissures, pulmonary agenesis, and/or truncus arteriosus; (iv) a fetus with bilateral anophthalmia, bushy eyebrows, pulmonary agenesis, heart malformation, and abnormal hand positioning. The phenotypic spectrum of PDAC syndrome has until now not included contractures or camptodactyly. Sequencing of STRA6 in unrelated members of families three and four identified a novel, shared homozygous splice site alteration (c.113 + 3_4delAA) that is predicted to be pathogenic. We hypothesize this may represent a unique disease allele in the Hmong. We also provide a focused review of all published PDAC syndrome cases with confirmed or inferred STRA6 mutations, illustrating the phenotypic and molecular variability that characterizes this disorder. © 2015 Wiley Periodicals, Inc.

    Mental and somatic health was compared between older Somali refugees and their pair-matched Finnish natives, and the role of pre-migration trauma and post-migration stressors among the refugees. One hundred and twenty-eight Somalis between 50-80 years of age were selected from the Somali older adult population living in the Helsinki area (N = 307). Participants were matched with native Finns by gender, age, education, and civic status. The BDI-21 was used for depressive symptoms, the GHQ-12 for psychological distress, and the HRQoL was used for health-related quality of life. Standard instruments were used for sleeping difficulties, somatic symptoms and somatization, hypochondria, and self-rated health. Clinically significant differences in psychological distress, depressive symptoms, sleeping difficulties, self-rated health status, subjective quality of life, and functional capacity were found between the Somali and Finnish groups. In each case, the Somalis fared worse than the Finns. No significant differences in somatization were found between the two groups. Exposure to traumatic events prior to immigrating to Finland was associated with higher levels of mental distress, as well as poorer health status, health-related quality of life, and subjective quality of life among Somalis. Refugee-related traumatic experiences may constitute a long lasting mental health burden among older adults. Health care professionals in host countries must take into account these realities while planning for the care of refugee populations. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Communication is key for the successful implementation of polio vaccination campaigns. The purpose of this study is to review and analyse the sources of information utilized by caregivers during polio supplementary immunization activities (SIAs) in Somali, Ethiopia in 2014 and 2015. Data on sources of information about the polio campaign were collected post campaign from caregivers by trained data collectors as part of house to house independent monitoring. The sources of information analysed in this paper include town criers (via megaphones), health workers, religious leaders, kebele leaders (Kebele is the lowest administrative structure in Ethiopia), radio, television, text message and others. The repetition of these sources of information was analysed across years and zones for trends. Polio vaccination campaign coverage was also reviewed by year and zones within the Somali region in parallel with the major sources of information used in the respective year and zones. 57,745 responses were used for this analysis but the responses were received from polio SIAs. Zonal trends in using town criers as a major source of information in both study years remained consistent except in two zones. 87.5% of zones that reported at least 90% coverage during both study years had utilized town criers as a major source of information while the rest (12.5%) used health workers. We found that town criers were consistently the major source of information about the polio campaigns for Somali region parents and caregivers during polio immunization days held in 2014 and 2015. Health workers and kebele leaders were also important sources of information about the polio campaign for parents.

    2017-09-01

    The current study uses a multiple goal theoretical perspective to explore how Somali immigrant families living in Ohio, USA, make decisions regarding whether to vaccinate their children against human papillomavirus (HPV)-a leading cause of cervical cancer. A focus was placed on the communication goals of parents in HPV vaccine discussions with their child and health care provider. Semi-structured interviews were audiotaped, transcribed, and analyzed using a grounded theory approach. Key themes are the implications of the vaccine for early sexual activity, confusion between HPV and HIV (human immunodeficiency virus), the perception that the HPV vaccine is unnecessary, uncertainty about the vaccine's efficacy and side effects, avoidance of parent-child communication about the vaccine, and a preference for framing the vaccine as a health promotion behavior. Framing the threat of HPV in the context of initiation of sexual activity, uncertainty regarding vaccine efficacy, and anticipated regret account for the inconsistency in HPV vaccine uptake among Somali parents. Clinicians should consider talking about HPV as a distal versus an immediate threat and HPV vaccine uptake as a health-promotion behavior rather than a sexually transmitted infection prevention behavior.

    The primary purpose of this study was to examine relations between trauma exposure, post-resettlement stressors, perceived discrimination, and mental health symptoms in Somali adolescent refugees resettled in the U.S. Participants were English-speaking Somali adolescent refugees between the ages of 11 and 20 (N = 135) who had resettled in the U.S. Participants were administered an interview battery comprising self-report instruments that included the UCLA Posttraumatic Stress Disorder (PTSD) Index, the War Trauma Screening Scale, the Every Day Discrimination scale, the Adolescent Post-War Adversities Scale, and the Acculturative Hassles Inventory. Results indicated that cumulative trauma was related to PTSD and depression symptoms. Further, post-resettlement stressors, acculturative stressors, and perceived discrimination were also associated with greater PTSD symptoms after accounting for trauma, demographic, and immigration variables. Number of years since resettlement in the US and perceived discrimination were significantly related to depressive symptoms, after accounting for trauma, demographic, and immigration variables. Further research elucidating the relations between post-resettlement stressors, discrimination, and mental health of refugee adolescents may inform intervention development.

    The development of the domestic gas market in Indonesia, the world's largest liquefied natural gas producing country, is described as part of the overall impact of the country's oil and gas production. The first large scale use of natural gas in Indonesia was established in 1968 when a fertiliser plant using gas as the feedstock was built. Ultimately, through increased yields, this has enabled Indonesia to be self-sufficient in rice and an exporter of fertiliser. Problems which stand in the way of further developments include: capital, though Pertamina and PGN are perceived as attractive for foreign investment; the lack of a regulatory framework for gas; geographical constraints, among them the fact that the gas deposits are remote from the largest population concentrations; lack of infrastructure. There are nevertheless plans for expansion and the provision of an integrated gas pipeline system. Pertamina, which has responsibility for all oil and gas developments, and PGN, whose primary role has been as a manufacturer and distributor of gas, are now working together in the coordination of all gas activities.

    Hmong are one of the immigrant Asian subgroups with increasing rates of obesity, type 2 diabetes and CVD. Despite their population growth in the USA and declining health status, no research has investigated the appropriateness of dietary assessment measures, including FFQ and 24 h dietary recalls among Hmong. The present study compared the nutrient information obtained through a 24 h dietary recall method with that collected using the Block Kid's Food Frequency Questionnaire (Block FFQ) among Hmong-American children (n 335) of 9-18 years of age. For this purpose, two 24 h dietary recalls were collected during non-consecutive days and averaged for comparison. The Block FFQ was administered on the day of the second 24 h recall and the two methodologies were also compared using t tests. Among all children, Block FFQ nutrient estimates for vitamin A, vitamin C and food group servings for vegetables and fruits were significantly higher than those assessed through the 24 h dietary recalls (Pfood group servings for grains and meat and beans were significantly higher among all participants when assessed through the 24 h dietary recalls than through the Block FFQ (Pfood options otherwise missed in the Block FFQ. We recommend the modification of the current Block FFQ to appropriately reflect cultural food/beverage items of the population in interest.

    The genome of the red vizcacha rat (Rodentia, Octodontidae, Tympanoctomys barrerae) is the largest of all mammals, and about double the size of their close relative, the mountain vizcacha rat Octomys mimax, even though the lineages that gave rise to these species diverged from each other only about 5 Ma. The mechanism for this rapid genome expansion is controversial, and hypothesized to be a consequence of whole genome duplication or accumulation of repetitive elements. To test these alternative but nonexclusive hypotheses, we gathered and evaluated evidence from whole transcriptome and whole genome sequences of T. barrerae and O. mimax. We recovered support for genome expansion due to accumulation of a diverse assemblage of repetitive elements, which represent about one half and one fifth of the genomes of T. barrerae and O. mimax, respectively, but we found no strong signal of whole genome duplication. In both species, repetitive sequences were rare in transcribed regions as compared with the rest of the genome, and mostly had no close match to annotated repetitive sequences from other rodents. These findings raise new questions about the genomic dynamics of these repetitive elements, their connection to widespread chromosomal fissions that occurred in the T. barrerae ancestor, and their fitness effects-including during the evolution of hypersaline dietary tolerance in T. barrerae. ©The Author(s) 2017.

    Refugee adolescents often immigrate to a new society because of experiences of persecution and trauma, which can have profound effects on their mental health. Once they immigrate, many refugees experience stressors related to resettlement and acculturation in the new society. The current study examined relationships among acculturation styles and hassles and the well-being of young refugees as well as the role of gender. Data were collected from 135 young refugees (M age = 15.39, SD = 2.2; 62 % male) from Somalia resettled in the United States The findings from our study indicate that in addition to trauma history, acculturative hassles and acculturation style impact the wellbeing of Somali refugee adolescents. These findings indicate the need to understand both past experiences as well as current challenges. Potential areas for intervention are discussed.

    Full Text Available Abstract Background Many ethnic minority populations have poorer health than the general population. However, there is limited knowledge on the possible ethnic gap in physical mobility. We aim to examine the prevalence of mobility limitations in working-age Russian, Somali and Kurdish origin migrants in comparison to the general population in Finland. We also determine whether the association between ethnic group and mobility limitation remains after taking into account socio-economic and health-related factors. Methods We used data from the Finnish Migrant Health and Wellbeing Study (Maamu and the Finnish Health 2011 Survey. The participants comprised 1880 persons aged 29–64 years. The age-adjusted prevalence of difficulties in various mobility tasks was calculated using predictive margins. Logistic regression analysis was used to examine the association between socio-economic, health- and migration-related factors and mobility limitation (self-reported difficulty in walking 500 m or stair climbing. The association between ethnic group and mobility limitation was calculated using logistic regression analysis. Results Mobility limitations were much more prevalent among Somali origin women (46 % and Kurdish origin men (32 % and women (57 % compared to men and women in the general Finnish population (5–12 %. In Russian origin men and women, the prevalence of mobility limitation (7–17 % was similar to the general Finnish population. Socio-economic and health-related factors, but not migration-related factors (time lived in Finland and language proficiency in Finnish or Swedish, were found to be associated with mobility limitation in the studied populations. Somali and Kurdish origin migrants were found to have increased odds for mobility limitation compared to the general Finnish population, even after adjusting for socio-economic and health-related factors (Somalis odds ratio [OR] 3.61; 95 % confidence interval [CI] 2.07–6.29, Kurds

    Full Text Available Abstract Background Somali migrants fleeing the civil war in their country face punishing journeys, the loss of homes, possessions, and bereavement. On arrival in the host country they encounter poverty, hostility, and residential instability which may also undermine their mental health. Methods An in-depth and semi-structured interview was used to gather detailed accommodation histories for a five year period from 142 Somali migrants recruited in community venues and primary care. Post-codes were verified and geo-mapped to calculate characteristics of residential location including deprivation indices, the number of moves and the distances between residential moves. We asked about the reasons for changing accommodation, perceived discrimination, asylum status, traumatic experiences, social support, employment and demographic factors. These factors were assessed alongside characteristics of residential mobility as correlates of ICD-10 psychiatric disorders. Results Those who were forced to move homes were more likely to have an ICD-10 psychiatric disorder (OR = 2.64, 1.16-5.98, p = 0.02 compared with those moving through their own choice. A lower risk of psychiatric disorders was found for people with larger friendship networks (0.35, 0.14-0.84, p = 0.02, for those with more confiding emotional support (0.42, 0.18-1.0, p = 0.05, and for those who had not moved during the study period (OR = 0.21, 0.07-0.62, p = 0.01. Conclusions Forced residential mobility is a risk factor for psychiatric disorder; social support may contribute to resilience against psychiatric disorders associated with residential mobility.

    In November 2000, the TransAlta Energy Corp. began construction on its $400 million natural gas fuelled cogeneration project in Sarnia Ontario. The Sarnia Regional Cogeneration Project (SRCP) is designed to integrate a new 440 MW cogeneration facility to be built at the Sarnia Division of Dow Chemicals Canada Inc. with nearby existing generators totaling 210 MW at Dow and Bayer Inc. At 650 MW, the new facility will rank as Canada's largest cogeneration installation. Commercial operation is scheduled for October 2002. TransAlta owns three natural gas fuelled cogeneration facilities in Ontario (in Ottawa, Mississauga and Windsor) totaling 250 MW. The cost of electric power in Ontario is currently controlled by rising natural gas prices and the supply demand imbalance. This balance will be significantly affected by the possible return to service of 2000 MW of nuclear generating capacity. The SRCP project was announced just prior to the Ontario Energy Competition Act of October 1998 which committed the province to introduce competition to the electricity sector and which created major uncertainties in the electricity market. Some of the small, 25 MW projects which survived the market uncertainty included the Toronto-based Toromont Energy Ltd. project involving gas fuelled cogeneration and methane gas generation from landfill projects in Sudbury and Waterloo. It was emphasized that cogeneration and combined heat and power projects have significant environmental advantages over large combined cycle facilities. The Ontario Energy Board is currently considering an application from TransAlta to link the SRCP facility to Ontario's Hydro One Network Inc.'s transmission grid. 1 fig

    Oral health disparities related to socioeconomic status have been well described in the U.S., but oral health among refugee groups has not been well characterized. This article examines oral health among Somali refugees in Massachusetts. Eighty-three (83) participants were purposively selected for an in-depth, open-ended interview related to oral health. Older individuals associated use of the stick brush with the Islamic practice of cleansing before prayer. When unable to find stick brushes in the U.S., many adopted the Western toothbrush. Parents expressed concern that their children had adopted U.S. practices of brushing with a toothbrush only once or twice a day. Somali oral health practices have changed following arrival to the U.S., but the underlying model for oral health care remains rooted in Islam. By acknowledging the value of traditional practices, dentists may communicate the value of Western preventive and restorative dentistry, and recommend approaches to integrating the two.

    The aim of the present paper was to describe food and nutrient intake among 12-month-old Norwegian-Somali and Norwegian-Iraqi infants, with a focus on iron and vitamin D intake. A cross-sectional survey was conducted from August 2013 through September 2014. Eighty-nine mothers/infants of Somali origin and 77 mothers/infants of Iraqi origin residing in Eastern Norway participated in the study. Data were collected using two 24-h multiple-pass recalls. Forty percent of the Norwegian-Somali infants and 47% of the Norwegian-Iraqi infants were breastfed at 12 months of age ( p = 0.414). Median energy percentages (E%) from protein, fat and carbohydrates were within the recommended intake ranges, except the level of saturated fats (12-13 E%). Median intakes of almost all micronutrients were above the recommended daily intakes. Most of the infants consumed iron-enriched products (81%) and received vitamin D supplements (84%). The median intakes of iron and vitamin D were significantly higher among infants receiving iron-enriched products and vitamin D supplements compared to infants not receiving such products ( p food and nutrient intake of this group of infants in general seems to be in accordance with Norwegian dietary recommendations. Foods rich in iron and vitamin D supplements were important sources of the infants' intake of iron and vitamin D and should continue to be promoted.

    to explore the sexual relationship and couples' perceptions about intimate partner support following childbirth. a hermeneutic design using a naturalistic inquiry framework as a qualitative proxy for medical anthropology. Data were collected using a fictional and culturally-specific narrative during focus group discussions (FGDs) in early 2011. Analysis was conducted by 'functional narrative analysis' and interpreted for conceptual constructions. Recruitment was by snowball and purposive sampling. a diasporic context among participants living in six urban centres across Sweden. successful recruitment included 16 Somali-Swedish fathers and 27 mothers. Three FDGs were conducted with fathers (3-7 participants) and seven with mothers (3-6 participants). within day 40 post partum, parents learn to rely on each other in the absence of traditional support networks. After the first 40 days, the re-introduction of sexual intimacy is likely to occur. Of the fathers experiencing postpartum sexual aversion, these seemed to experience 'existential angst' resulting from a combination of profound remorse over having put the partner into what they perceived as a life-threatening situation during childbirth and their perceived moral and ethical obligations to provide support in this setting. Mothers in general did not directly discuss their own sexuality. Women could imagine men's sexual aversion after witnessing childbirth. However, they seemed unaware of men's potential for angst. Mothers are situated between the loss of traditional postpartum support networks, comprised of close female kin, and their own newly-defined responsibilities in the host setting. Fathers embrace their new role. Both partners articulated the mother's new role as enhancing autonomy and independence in the host setting. However, women held mixed attitudes about fathers replacing traditional kin support. to date, late postpartum aftercare for immigrant African parents is anecdotally linked to evidence

    Communication problems due to language and cultural differences between health care professionals and patients are widely recognized. Finns are described as more silent whereas one concurrent large immigrant group, the Somalis, are described as more open in their communication. The aim of the study was to explore physicians-nurses/midwives' communication when providing reproductive and maternity health care to Somali women in Finland. Four individual and three focus group interviews were carried out with 10 gynecologists/obstetricians and 15 nurses/midwives from five selected clinics. The health care providers considered communication (including linguistic difficulties), cultural traditions, and religious beliefs to be problems when working with Somali women. Male and female physicians were generally more similar in communication style, interpersonal contacts, and cultural awareness than the nurses/midwives who were engaged in more partnership-building with the Somali women in the clinics. Despite the communication and cultural problems, there was a tentative mutual understanding between the Finnish reproductive health care professionals and the Somali women in the clinics.

    Type 2 diabetes represents a major health problem worldwide, with immigrants strongly contributing to the increase in diabetes in many countries. Norway is not immune to the process, and immigrants in the country are experiencing an increase in the prevalence of diabetes after arrival. However, the dynamics of these transitions in relation to the duration of residence in the new environment in Norway are not clearly understood. From this background, a cross-sectional quantitative study using a respondent-driven sampling method was conducted among 302 Somali women living in Oslo area. The results show that 41% of the study participants will be at risk for developing diabetes in the coming 10 years, which coincides with 85% of the study participants being abdominally obese. Significant associations were found between years of stay in Norway and the risk for diabetes with those who lived in Norway >10 years, having twofold higher odds of being at risk for developing diabetes compared to those who lived in Norway ≤5 years (OR: 2.16, CI: 1.08-4.32). Understanding the mechanisms through which exposure to the Norwegian environment leads to higher obesity and diabetes risk may aid in prevention efforts for the rapidly growing African immigrant population.

  7. Neoliberal Sexual Humanitarianism and Story-Telling: The case of Somaly Mam

    2016-09-01

    Full Text Available Stories of trafficking into the sex industry in Cambodia are a popular feature in local and international media, academic and development literature, policy and humanitarian debates, social and political discourse, and NGO interventions. These stories are powerful for their ability to evoke deep emotions and outrage from their intended audiences. However, they are equally powerful for the ways in which they can cause harm—namely to already marginalised populations of migrants and people involved in the sex trade either by choice, circumstance or coercion. One of the most contentious contemporary trafficking stories is that of the controversial case of Somaly Mam—the self-declared ‘sex slave’ turned ‘modern-day hero’. This paper outlines Mam’s prolific trajectory of self-representation according to the tropes of sexual humanitarianism and argues that these narratives helped to set in motion one of the most lucrative, and in many ways, most exploitative and problematic anti-trafficking endeavours in Cambodia, to date. The paper concludes with offering suggestions for how the anti-trafficking industry might better address real cases of trafficking and exploitation by focusing on structural violence and systemic injustice rather than on sensationalised humanitarian rhetoric, which can perpetuate harms.

    2012-01-01

    We observed a group of three young female Somali wild asses to develop an ethogram of social behavior in the first phase of a longer term study of social, sexual, and maternal/infant behavior. The most unexpected finding was the frequency and extent of aggressive interactions, which included Charge, Drive, Neck Wrestle, Head Butt, and Body Slam, behaviors previously reported only for males of other equid species. The overall frequency of aggressive behavior was higher than that of affiliative behavior (84±16.5 vs. 32±5.5, P=0.03), yet no injuries occurred. The dyadic directionality of aggressive behavior suggested a dominance hierarchy, a feature not previously reported for either wild ass or domestic donkeys. The aggression observed may be an accurate representation of the behavior of this species, or their relatively young ages, or their recent transfer from their natal group through quarantine and into a new enclosure may have heightened agonistic tendencies. Further studies will determine whether with time their aggressive behavior becomes more intense or dissipates with maturity. © 2011 Wiley Periodicals, Inc.

    Background: There is no recent information about the prevalence and distribution of schistosomiasis in the Somali national regional state of Ethiopia. Ethiopia launched the national integrated neglected tropical diseases (NTDs) Master Plan in June 2013. The Master Plan identified mapping NTDs as a prerequisite for launching control programs. Therefore it is important to understand the prevalence and distribution of schistosomiasis in respective regions. Materials and Methods: From February to March 2011, a cross-sectional survey was done in school-aged children from six districts of Afder Gode zone. Urine samples were collected and examined for ova of Schistosoma haematobium using the sedimentation technique and stool samples were collected and examined for S. mansoni using the Kato-Katz technique. A semistructured questionnaire was used to collect sociodemographic characteristics of the participants. Results: Of the 523 children, 513 (98%) of them participated in the study. The prevalence of S. haematobium was 16.0% (95% confidence interval (CI); 12.8-19.2). The rate of the disease was not uniform across the various six communities studied (x2 = 208.8, P region with varying distribution across the districts. According to the World Health Organization, mass drug administration should be considered in some of the districts. PMID:24672176

    Full Text Available Case summary A 3-month-old intact male Somali cat was evaluated for a history of seizures, hypoglycaemia and mental dullness 4 weeks after being bitten in the head by a dog. The cat’s body size and weight were approximately half that of his littermates and its haircoat was woolly, with fewer guard hairs. Multiple hypoglycaemic episodes were documented over a period of 4 weeks, which resolved rapidly after correction of the hypoglycaemia. Juvenile hyposomatotropism was presumptively diagnosed by demonstrating low circulating levels of insulin-like growth factor 1 and after exclusion of other endocrine and non-endocrine causes of small stature and hypoglycaemia. The cat’s intermittent hypoglycaemia resolved spontaneously within 1 month and the cat never showed any more neurological signs. Nevertheless, the physical retardation and the coat abnormalities remained unchanged. A year later, the cat was diagnosed with chronic kidney disease IRIS stage 2. Relevance and novel information Hyposomatotropism is an extremely rare feline endocrinopathy. This is the second case reported in the veterinary literature, and the only one to describe hypoglycaemic events associated with growth hormone deficiency. Although hypoglycaemia is one of the most common disease manifestations in children with pituitary dwarfism, this has not yet been reported in veterinary medicine.

    Full Text Available Objective. Refugees are at high risk for mental health problems due to trauma in their pasts and to acculturation stress as they settle in a new country. To develop efficient health services to meet the needs of refugees from various regions, an understanding of how they make sense of and prefer to cope with mental health problems is warranted. This study aims to investigate lay explanatory models of depression and preferred coping strategies among Somali refugees in Norway.Methods. The study used a mixed-method design with a vignette describing a moderately depressed person based on ICD-10 criteria. Firstly, a survey study was performed among Somali refugees (n = 101. Respondents were asked to provide advice to the vignette character, completing the Cross-Cultural Depression Coping Inventory and the General Help-Seeking Questionnaire. Secondly, focus group interviews (n = 10 were done separately with males and females to examine the relationship between the explanatory models of depression and preferred coping strategies.Results. The participants showed a strong preference for coping with depression by religious practices and reliance on family, friends, and their ethnic/religious community rather than seeking professional treatment from public health services (e.g., medical doctors, psychologists. Depressive symptoms were conceptualized as a problem related to cognition (thinking too much and emotion (sadness, but not with biological mechanisms, and were thought to result from spiritual possessions, stress from social isolation, and/or past trauma. Independent of time in exile, the participants showed a strong identification with their ethnic origin and associated values. As participants emphasized the need to obey and follow the viewpoint of elders, fathers, and spiritual leaders, these authorities seemed to be gatekeepers for access to mental health services. Conclusion. The results highlight that mental health programs for Somali refugees

    Norway has a low incidence and mortality rate of cervical cancer, which is mainly due to the high participation rate of women in cervical cancer screening. However, the attendance of cervical cancer screening was reported to be low among immigrant women. For this reason, we conducted a qualitative study to obtain better insight into perceived barriers and challenges to cervical cancer screening among Somali and Pakistani women in the Oslo region. A convenient sample of 35 (18 Pakistani, 17 Somali) women were recruited for the study in collaboration with Somali and Pakistani community partners. Focus group discussions were used to explore barriers and facilitators to cervical cancer screening, whereas the Ecological Model was used as the framework for the study. The study found three levels of barriers to cervical cancer screening. The individual level included a lack of understanding of the benefits of the screening. The sociocultural level included the stigma attached to the disease and the belief that women who are unmarried are sexually inactive. The system-related level included a lack of trust toward the health care system. Based on the study results, and using a common denominator approach for the immigrant groups included, the study recommends three communication strategies with the potential to improve women's participation in cervical cancer screening: 1) in-person communication and information material at health centers; 2) verbal communication with women through seminars and workshops to educate them about their risk of cancer and the importance of screening and 3) the initiation of better recall through SMS and letters written in native languages. Finally, an intervention study that compares the aforementioned strategies and proves their effectiveness in increasing immigrant women's participation in cervical cancer screening is recommended.

    Despite the gradual decrease in childhood lead poisoning in the United States, the risk for lead poisoning among African refugee children who resettle in the United States remains elevated. Communication methods implemented by resettlement agencies in the public health system for preventing childhood lead poisoning in this at-risk population warrant further investigation. We utilized structured interviews with key stakeholders (resettlement agencies, social service agencies developed by African refugees and resettled Somali refugees) involved in the refugee resettlement process to (1) describe the agency's role in the refugee resettlement process; (2) examine communication methods utilized and barriers experienced by the public health system in reference to childhood lead poisoning; (3) describe the refugee population's perception of childhood lead poisoning; (4) examine general challenges experienced by the public health system and the refugee population during the resettlement process; and (5) describe stakeholders' recommendations to improve health communication efforts. Based on our findings, we propose that communities are important determinants in health-related problems for refugee populations. Each community has its own environment and public health system that interacts with each other to influence health risks and risk perceptions of its populations. We advocate that understanding a community's ecology and implementing a culture-centered approach is essential for the public health system to help educate and prevent communication inequalities and health disparities among an at-risk African refugee population. This action can reduce a population's resistance to communication and help build a community's capacity to address a persistent public health problem, such as childhood lead poisoning.

    Ethiopia experienced several WPV importations with a total of 10 WPV1 cases confirmed during the 2013 outbreak alone before it is closed in 2015. We evaluated supplemental immunization activities (SIAs), including lessons learned for their effect on the routine immunization program during the 2013 polio outbreak in Somali regional state. We used descriptive study to review documents and analyse routine health information system reports from the polio outbreak affected Somali regional state. All data and technical reports of the 15 rounds of polio SIAs from June 2013 through June 2015 and routine immunization coverages for DPT-Hib-HepB 3 and measles were observed. More than 93% of the SIAs were having administrative coverage above 95%. The trend of routine immunization for the two antigens, over the five years (2011 through 2015) did not show a consistent pattern against the number of SIAs. Documentations showed qualitative positive impacts of the SIAs strengthening the routine immunization during all courses of the campaigns. The quantitative impact of polio SIAs on routine immunization remained not so impressive in this study. Clear planning, data consistencies and completeness issues need to be cleared for the impact assessment in quantitative terms, in polio legacy planning as well as for the introduction of injectable polio vaccine through the routine immunization.

    Background Refugee families often encounter a number of acculturative and resettlement stressors as they make lives for themselves in host countries. These difficulties may be compounded by past trauma and violence exposure posing increased risk for mental health problems. Greater knowledge is needed about protective processes contributing to positive development and adjustment in refugee families despite risk (e.g., resilience). The aims of this research were to identify and examine strengths and resources utilized by Somali refugee children and families in the Boston area to overcome resettlement and acculturative stressors. Methods We used maximum variation sampling to conduct a total of nine focus groups: five focus groups (total participants N=30) among Somali refugee adolescents and youth capturing gender and a range of ages (15-25 years) as well as four focus groups of Somali refugee mothers and fathers in groups (total participants N=32) stratified by gender. Results Drawing from Conservation of Resources Theory (COR), we identified five forms of resources comprising individual, family and collective/community strengths: religious faith; healthy family communication; support networks and peer support. “Community talk” was identified as a community dynamic having both negative and positive implications for family functioning. Conclusions Protective resources among Somali refugee children and families can help to offset acculturative and resettlement stressors. Many of these locally occurring protective resources have the potential to be leveraged by family and community-based interventions. These findings are being used to design preventative interventions that build on local strengths among Somali refugees in the Boston area. PMID:25090142

    We studied the differences in the mean pre-pregnancy body mass index (BMI) and mean inter-pregnancy weight change in women of Russian, Somali and Kurdish origin and women in the general Finnish population. The population-based samples were from the Migrant Health and Wellbeing Study and the Health 2011 Survey conducted in six cities in Finland in 2010-2012. This study included women with at least one birth in Finland. Data on their previous pregnancies in Finland were obtained from the National Medical Birth Register for 318 Russian, 584 Somali and 373 Kurdish origin women and for 243 women in the general Finnish population (reference group). Data on pre-pregnancy weight and height were self-reported in early pregnancy. Linear logistic regression was the main method of analysis. The unadjusted mean pre-pregnancy BMI was higher in Somali (27.0 kg/m 2 , p<0.001) and Kurdish (25.8 kg/m 2 , p<0.001) women, but lower in Russian (22.2 kg/m 2 , p<0.001) women than in the reference group (24.1 kg/m 2 ). The adjusted coefficients for the difference in the mean pre-pregnancy BMI were -1.93 (95% CI -2.77 to -1.09) for Russian, 1.82 (95% CI 0.89-2.75) for Somali and 1.30 (95% CI 0.43-2.17) for Kurdish women compared with the reference group. Among women with at least two births, no statistically significant difference was observed in the mean inter-pregnancy weight change between the migrant groups and the reference group. Somali and Kurdish women had higher mean pre-pregnancy BMIs than women in the general Finnish population and may need special support and health promotion strategies for weight management.

RESULTS: Molecular genetic analysis performed for 3 of these patients revealed that all are homozygous for an 1165A>G mutation that causes skipping of exon 10 of the SBCAD gene....... Although there was no obvious consanguinity, all patients belong to the Hmong, an ancient ethnic group that originated in China and constitutes only 0.8% and 0.6% of the Minnesota and Wisconsin population, respectively. Dietary treatment was initiated in the neonatal period. Except for 1 patient who...... developed mild muscle hypotonia, all patients remain asymptomatic at ages ranging from 3 to 14 months of age. CONCLUSIONS: These cases suggest that SBCAD deficiency is another inborn error of metabolism detectable by newborn screening using tandem mass spectrometry. The continued efficacy of long...

    To examine breast-feeding and complementary feeding practices during the first 6 months of life among Norwegian infants of Somali and Iraqi family origin. A cross-sectional survey was performed during March 2013-February 2014. Data were collected using a semi-quantitative FFQ adapted from the second Norwegian national dietary survey among infants in 2006-2007. Somali-born and Iraqi-born mothers living in eastern Norway were invited to participate. One hundred and seven mothers/infants of Somali origin and eighty mothers/infants of Iraqi origin participated. Breast-feeding was almost universally initiated after birth. Only 7 % of Norwegian-Somali and 10 % of Norwegian-Iraqi infants were exclusively breast-fed at 4 months of age. By 1 month of age, water had been introduced to 30 % of Norwegian-Somali and 26 % of Norwegian-Iraqi infants, and infant formula to 44 % and 34 %, respectively. Fifty-four per cent of Norwegian-Somali and 68 % of Norwegian-Iraqi infants had been introduced to solid or semi-solid foods at 4 months of age. Breast-feeding at 6 months of age was more common among Norwegian-Somali infants (79 %) compared with Norwegian-Iraqi infants (58 %; P=0·001). Multivariate analyses indicated no significant factors associated with exclusive breast-feeding at 3·5 months of age. Factors positively associated with breast-feeding at 6 months were country of origin (Somalia) and parity (>2). Breast-feeding initiation was common among Iraqi-born and Somali-born mothers, but the exclusive breast-feeding period was shorter than recommended in both groups. The study suggests that there is a need for new culture-specific approaches to support exclusive breast-feeding and complementary feeding practices among foreign-born mothers living in Norway.

    There is pressing need for innovation in clinical research to more effectively recruit, engage, retain, and promote health among diverse populations overburdened by health disparities. The purpose of this study is to provide a detailed illustration of the cultural adaptation of an evidence-based intervention to bolster translational research with currently underserved communities. The cultural adaptation heuristic framework described by Barrera and colleagues is applied to the adaptation of a physical activity evidence-based intervention with adult Somali women. Widespread changes were required to ensure program feasibility and acceptability, including the reduction of assessment protocols and changes discordant with current trends in physical activity research. The cultural adaptation of evidence-based interventions offers an important mechanism for reducing health disparities. Improved reporting standards, assessment of features relevant to underserved communities, and greater funding requirements to ensure better representation are needed to promote more widespread access for all people.

    Full Text Available Assume that claims in a portfolio of insurance contracts are described by independent and identically distributed random variables with regularly varying tails and occur according to a near mixed Poisson process. We provide a collection of results pertaining to the joint asymptotic Laplace transforms of the normalised sums of the smallest and largest claims, when the length of the considered time interval tends to infinity. The results crucially depend on the value of the tail index of the claim distribution, as well as on the number of largest claims under consideration.

    2015-01-01

    Full Text Available The purpose of this research is to analyse the relationship between nonlinear dynamic character and individuals’ standing balance by the largest Lyapunov exponent, which is regarded as a metric for assessing standing balance. According to previous study, the largest Lyapunov exponent from centre of pressure time series could not well quantify the human balance ability. In this research, two improvements were made. Firstly, an external stimulus was applied to feet in the form of continuous horizontal sinusoidal motion by a moving platform. Secondly, a multiaccelerometer subsystem was adopted. Twenty healthy volunteers participated in this experiment. A new metric, coordinated largest Lyapunov exponent was proposed, which reflected the relationship of body segments by integrating multidimensional largest Lyapunov exponent values. By using this metric in actual standing performance under sinusoidal stimulus, an obvious relationship between the new metric and the actual balance ability was found in the majority of the subjects. These results show that the sinusoidal stimulus can make human balance characteristics more obvious, which is beneficial to assess balance, and balance is determined by the ability of coordinating all body segments.

    Full Text Available At the end of the Second World War the United Nations gave to Italy a special protectorate on the own former colony by the International Trusteeship System of Somalia, which concludes in 1960. During the Fifties there are many relationships between the italian men and the somali women: from these liaisons there are a lot of children which have different destinies and their history represents one of the heredity of the italian past in Africa. From this italo-somali métissage, rises an association who asks the recognition of all the pains suffered by a part of that community and in the same time it asks a collective reflections of the historic memories about the Trusteeship System.

  14. 'The child that tiire doesn't give you, God won't give you either.' The role of Rotheca myricoides in Somali fertility practices.

    Mire, Sada

    2016-12-01

    The paper introduces the Baanashada Dumarka, a Somali fertility therapy carried out by a spirit medium, known locally as 'Alaqad. Baanashada is aimed at women whose fertility issues are believed to be caused by spirits. The study also explores a component of the Baanashada, namely, the use of tiire (Rotheca myricoides), or the butterfly bush. Although Rotheca myricoides is known to possess a number of medicinal components as confirmed by studies of modern science, so far, there exist no studies on its potential (or lack of) fertility effects. Hence, the alleged fertility benefits of the butterfly bush need examining. In 2008 a British Somali woman died of herbs placed in her cervix by a traditional healer in Somaliland. This piece of information indicated not only the role of herbal medicine in fertility practices, but also the popularity of traditional reproductive medicine beyond border, class or educational background. Yet, current research into Somali women's health focuses mainly on Female Genital Mutilation (FGM), examined often without the context of wider cultural practices. This paper, however, suggests that rituals, beliefs and material culture play a paramount role in women's practices. For example, as explored elsewhere, the wagar, a wooden and sacred object made of the African olive, is critical for fertility practices. The current paper illuminates further the significance of reproduction practices in Somali society and the potential continuity of traditions associated with the perpetuation of kinship. It concludes that fertility rituals are part of a wider context of interaction with sacred landscapes, objects and archaeological sites, often associated with past legends in the Horn of Africa.

    The Precision ID Identity Panel was used to type 109 Somali individuals in order to obtain allele frequencies for the Somali population. These frequencies were used to establish a Somali HID-SNP database, which will be used for the biostatistic calculations in family and immigration cases. Genotypes obtained with the Precision ID Identity Panel were found to be almost in complete concordance with genotypes obtained with the SNPforID PCR-SBE-CE assay. In seven SNP loci, silent alleles were identified, of which most were previously described in the literature. The project also set out to compare different AmpliSeq™ workflows to investigate the possibility of using automated library building in forensic genetic case work. In order to do so, the SNP typing of the Somalis was performed using three different workflows: 1) manual library building and sequencing on the Ion PGM™, 2) automated library building using the Biomek ® 3000 and sequencing on the Ion PGM™, and 3) automated library building using the Ion Chef™ and sequencing on the Ion S5™. AmpliSeq™ workflows were compared based on coverage, locus balance, noise, and heterozygote balance. Overall, the Ion Chef™/Ion S5™ workflow was found to give the best results and required least hands-on time in the laboratory. However, the Ion Chef™/Ion S5™ workflow was also the most expensive. The number of libraries that may be constructed in one Ion Chef™ library building run was limited to eight, which is too little for high throughput workflows. The Biomek ® 3000/Ion PGM™ workflow was found to perform similarly to the manual/Ion PGM™ workflow. This argues for the use of automated library building in forensic genetic case work. Automated library building decreases the workload of the laboratory staff, decreases the risk of pipetting errors, and simplifies the daily workflow in forensic genetic laboratories.

    2006-01-01

    Full Text Available In order to estimate the hazard rate distribution of the largest seismic events in Vrancea, South-Eastern Carpathians, we study temporal properties of historical and instrumental catalogues of seismicity. First, on the basis of Generalized Extreme Value theory we estimate the average return period of the largest events. Then, following Bak et al. (2002 and Corral (2005a, we study scaling properties of recurrence times between earthquakes in appropriate spatial volumes. We come to the conclusion that the seismicity is temporally clustered, and that the distribution of recurrence times is significantly different from a Poisson process even for times largely exceeding corresponding periods of foreshock and aftershock activity. Modeling the recurrence times by a gamma distributed variable, we finally estimate hazard rates with respect to the time elapsed from the last large earthquake.

    Marine gravity data derived from satellite altimeters are effective tools in mapping fine-scale tectonic features of the ocean basins such as pseudofaults, fracture zones and seamounts, particularly when the ocean basins are carpeted with thick sediments. We use high-resolution satellite-generated gravity and seismic reflection data to map boundaries of pseudofaults and transferred crust related to the Paleocene spreading ridge propagation in the Arabian and its conjugate Eastern Somali basins. The study has provided refinement in the position of previously reported pseudofaults and their spatial extensions in the conjugate basins. It is observed that the transferred crustal block bounded by inner pseudofault and failed spreading ridge is characterized by a gravity low and rugged basement. The refined satellite gravity image of the Arabian Basin also revealed three seamounts in close proximity to the pseudofaults, which were not reported earlier. In the Eastern Somali Basin, seamounts are aligned along NE-SW direction forming ∼300 km long seamount chain. Admittance analysis and Flexural model studies indicated that the seamount chain is isostatically compensated locally with Effective Elastic Thickness (Te) of 3-4 km. Based on the present results and published plate tectonic models, we interpret that the seamounts in the Arabian Basin are formed by spreading ridge propagation and are associated with pseudofaults, whereas the seamount chain in the Eastern Somali Basin might have probably originated due to melting and upwelling of upper mantle heterogeneities in advance of migrating/propagating paleo Carlsberg Ridge.

    In 1998, Electric Power Company of Macedonia and the International Bank for Development and Reconstruction, started the Power System Improvement Project a part of which is the Project for rehabilitation of the six largest Hydro Power Plants (HPPs) in the Republic of Macedonia. The six largest Hydro Power Plants (HPP Vrutok, HPP Raven, HPP Globocica, HPP Tikves and HPP Spilje and HPP Vrben) represent 91% of the country's hydropower capacity. The rehabilitation program is divided in five parts (contracts) and covers the refurbishment of: turbine runners, turbine and generator bearings, governors, inlet valves; butterfly valves, including accessories and control systems; generators, excitation system and voltage regulation; control system, protection and LV auxiliaries; switch gears and control gears in 220 kV, 110 kV and 35 kV substations. At the moment, only the implementation of switch gears has started, the first phase is already finished, and 50 % of the rehabilitation works for HPP Vrutok, the largest HPP, has been finished. With the realization of this project, greater hydropower production is expected. It also expected that HPPs will become a more vital part of the Macedonian power system

Preliminary construction on the 200-acre site started in Jan. 1969 with clearing and contouring of the main plant and sulfur storage sites. Initial rough grading started in the early summer, after spring breakup was over. Delivery of most of the big items was made by rail because the local secondary roads were inadequate for them. Concrete has been a large item. The contractor has its own batch plant on the site for the estimated 28,000 cu yd which will be needed for the whole job. Dominating the construction site from the start has been the high sulfur plant stack, first of the major items to be finished. It will serve to dispose of effluent from the largest sulfur recovery unit in Canada. It is 465 ft high, one of the largest in Alberta, and a significant contribution to pollution control and environmental protection.

    Full Text Available Sustainability transition is changing the role and function of banks, specially their products and services also in relation to stakeholders. Banks are one of the main actors supporting the transition to sustainable economy. The purpose of this study is to emphasise the role of world’s largest banks in that process. Banks are slowly responding to the new demand of sustainability and responsibility, and they try to align with it. The paper is based on an overview of the world’s five largest banks that employ corporate social responsibility (CSR reporting standards, together with detailed enumeration of pro-environmental activities included in the reports. The first section of this paper presents the most popular approaches to the problem at hand, as reported in professional literature. Section two presents the characteristics of the CSR actions in banks. The third section discusses the environmental actions of the biggest banks in Global Reporting Initiative (GRI reporting the most popular standard for reporting non-financial information. And the last part of the paper presents the conclusions resulting from the article. The research was conducted using a variety of sources, such as scientific articles, statistical data, CSR reports of the world’s largest banks, as well reporting principles and standard disclosures. The basic method used in the process of writing was a critical analysis of literature and reports concerning the CSR reporting standards, environmental responsibilities of different kinds of entities, as well as own observations based on special reports of banks. In the article, also the analysis of financial market data, induction method and comparison method have been used. The main conclusions of the analysis of the CSR reports disclosed by the world’s largest banks confirm all three of the theses presented in the article. The findings suggest that the banks under study can be regarded as environmentally responsible

    Large body size of ectothermic species can be correlated with high life expectancy. We assessed the longevity of the World's largest chameleon, the Parson's chameleon Calumma parsonii from Madagascar by using skeletochronology of phalanges taken from preserved specimens held in European natural history museums. Due to the high bone resorption we can provide only the minimum age of each specimen. The highest minimum age detected was nine years for a male and eight years for a female, confirming that this species is considerably long living among chameleons. Our data also show a strong correlation between snout-vent length and estimated age. Copyright © 2017 Elsevier Inc. All rights reserved.

    Sasthamkotta lake, the largest freshwater lake in Kerala, serves as a source for drinking water for more than half a million people. Environmental 137 Cs analysis done on undisturbed sediment core samples reveals that the recent rate of sedimentation is not uniform in the lake. The useful life of lake is estimated as about 800 years. The δD and δ 18 O values of the lake waters indicate that the lake is well mixed with a slight variation horizontally. The stable isotope studies on well waters from the catchment indicate hydraulic communication with the lake and lake groundwater system is flow-through type. Analytical model also supports this view.

    2014-07-15

    Studies on remote, uninhabited, near-pristine reefs have revealed surprisingly large populations of large reef fish. Locations such as the northwestern Hawaiian Islands, northern Marianas Islands, Line Islands, U.S. remote Pacific Islands, Cocos-Keeling Atoll and Chagos archipelago have much higher reef fish biomass than islands and reefs near people. Much of the high biomass of most remote reef fish communities lies in the largest species, such as sharks, bumphead parrots, giant trevally, and humphead wrasse. Some, such as sharks and giant trevally, are apex predators, but others such as bumphead parrots and humphead wrasse, are not. At many locations, decreases in large reef fish species have been attributed to fishing. Fishing is well known to remove the largest fish first, and a quantitative measure of vulnerability to fishing indicates that large reef fish species are much more vulnerable to fishing than small fish. The removal of large reef fish by fishing parallels the extinction of terrestrial megafauna by early humans. However large reef fish have great value for various ecological roles and for reef tourism. Copyright © 2014 Elsevier Ltd. All rights reserved.

  5. Initiating a different story about immigrant Somali parents’ support of their primary school children’s education

    Full Text Available The ability of parents to nurture and support their children during their primary school years is considered to be fundamental for the child’s development and learning. Teachers and educational psychologists assign great prominence to parental involvement as a tool to advance educational success for children, especially for those who are faced with disadvantages. In the past two decades, we have seen South African schools radically shifting from being racially and ethnically homogenous to becoming culturally, ethnically and linguistically heterogeneous. It is especially the schools in the lower socioeconomic areas that find themselves under tremendous pressure to serve their growing immigrant school population. Not enough is known about the cultural capital that lies embedded in these learners’ home contexts and the roles that their parents play in their education. In this manuscript, I investigate the potential intersectionality of school and home and critique the affiliation between teachers and immigrant parents as an important dimension of learning success in the primary school. I situate the discussion in a community school with a strong Somali immigrant population.

  6. The Impact of Food Consumption, Government Type and Effectiveness, on the Rate of Somali Maritime Piracy, 2000-2008

    2011-10-01

    Full Text Available The analysis of maritime piracy off the Horn of Africa is still a developing area of academic research. The work that has been conducted to date has remained largely qualitative.   Two recurring assumptions made but not empirically tested in this area of research are 1 the perceived link between government stability and the rate of maritime piracy, and 2 drought conditions implying food shortages in Somalia, and their impact on the rate of maritime piracy off the Horn of Africa.  The findings of this project show a strong increase in maritime piracy following the transition from assorted Islamic Courts to the Transitional Federal Government (TFG.  However, variations in the consumption of staple foodstuffs, and an index of the World Bank Governance Indicators do not have a significant impact on the frequency of maritime piracy in the region.  If maritime piracy off the Somali coast is to be eliminated, rather than policed, efforts should be made to encourage the development of governmental institutions that utilize culturally-respected institutions supported by the local populace.

    Carbon and energy fluxes between lakes and the atmosphere are important aspects of hydrology, limnology, and ecology studies. China's largest freshwater lake, the Poyang lake experiences tremendous water-land transitions periodically throughout the year, which provides natural experimental settings for the study of carbon and energy fluxes. In this study, we use the eddy covariance technique to explore the seasonal and diurnal variation patterns of sensible and latent heat fluxes of Poyang lake during its high-water and low-water periods, when the lake is covered by water and mudflat, respectively. We also determine the annual NEE of Poyang lake and the variations of NEE's components: Gross Primary Productivity (GPP) and Ecosystem Respiration (Re). Controlling factors of seasonal and diurnal variations of carbon and energy fluxes are analyzed, and land cover impacts on the variation patterns are also studied. Finally, the coupling between the carbon and energy fluxes are analyzed under different atmospheric, boundary stability and land cover conditions.

    Full Text Available Among the large-scale facilities operated at the Center for Lightweight-Production-Technology of the German Aerospace Center in Stade BALU is the world's largest research autoclave. With a loading length of 20m and a loading diameter of 5.8 m the main objective of the facility is the optimization of the curing process operated by components made of carbon fiber on an industrial scale. For this reason, a novel dynamic autoclaving control has been developed that is characterized by peripheral devices to expend the performance of the facility for differential applications, by sensing systems to detect the component state throughout the curing process and by a feedback system, which is capable to intervene into the running autoclave process.

    Stohler, F.

    2004-01-01

    This article describes how a small Swiss electricity utility has broken out of its traditional role in power generation and the distribution of electricity and gone into the production of wood pellets. The pellets, which are made from waste wood (sawdust) available from wood processing companies, are produced on a large scale in one of Europe's largest pellets production facilities. The boom in the use of wood pellets for heating purposes is discussed. The article discusses this unusual approach for a Swiss power utility, which also operates a wood-fired power station and is even involved in an incineration plant for household wastes. The markets being aimed for in Switzerland and in Europe are described, including modern low-energy-consumption housing projects. A further project is described that is to use waste wood available from a large wood processing facility planned in the utility's own region

    Reforestation is a critical means of addressing the environmental and social problems of deforestation. China's Grain-for-Green Program (GFGP) is the world's largest reforestation scheme. Here we provide the first nationwide assessment of the tree composition of GFGP forests and the first combined ecological and economic study aimed at understanding GFGP's biodiversity implications. Across China, GFGP forests are overwhelmingly monocultures or compositionally simple mixed forests. Focusing on birds and bees in Sichuan Province, we find that GFGP reforestation results in modest gains (via mixed forest) and losses (via monocultures) of bird diversity, along with major losses of bee diversity. Moreover, all current modes of GFGP reforestation fall short of restoring biodiversity to levels approximating native forests. However, even within existing modes of reforestation, GFGP can achieve greater biodiversity gains by promoting mixed forests over monocultures; doing so is unlikely to entail major opportunity costs or pose unforeseen economic risks to households.

    2014-01-01

    An apparent absence of Silurian fishes more than half-a-metre in length has been viewed as evidence that gnathostomes were restricted in size and diversity prior to the Devonian. Here we describe the largest pre-Devonian vertebrate (Megamastax amblyodus gen. et sp. nov.), a predatory marine osteichthyan from the Silurian Kuanti Formation (late Ludlow, ~423 million years ago) of Yunnan, China, with an estimated length of about 1 meter. The unusual dentition of the new form suggests a durophagous diet which, combined with its large size, indicates a considerable degree of trophic specialisation among early osteichthyans. The lack of large Silurian vertebrates has recently been used as constraint in palaeoatmospheric modelling, with purported lower oxygen levels imposing a physiological size limit. Regardless of the exact causal relationship between oxygen availability and evolutionary success, this finding refutes the assumption that pre-Emsian vertebrates were restricted to small body sizes.

  14. Largest US oil and gas fields, August 1993

    International Nuclear Information System (INIS)

    1993-01-01

    The Largest US Oil and Gas Fields is a technical report and part of an Energy Information Administration (EIA) series presenting distributions of US crude oil and natural gas resources, developed using field-level data collected by EIA's annual survey of oil and gas proved reserves. The series' objective is to provide useful information beyond that routinely presented in the EIA annual report on crude oil and natural gas reserves. These special reports also will provide oil and gas resource analysts with a fuller understanding of the nature of US crude oil and natural gas occurrence, both at the macro level and with respect to the specific subjects addressed. The series' approach is to integrate EIA's crude oil and natural gas survey data with related data obtained from other authoritative sources, and then to present illustrations and analyses of interest to a broad spectrum of energy information users ranging from the general public to oil and gas industry personnel

    We have observed a large glitch in the Crab pulsar (PSR B0531+21). The glitch occurred around MJD 58064 (2017 November 8) when the pulsar underwent an increase in the rotation rate of Δν = 1.530 × 10-5 Hz, corresponding to a fractional increase of Δν/ν = 0.516 × 10-6 making this event the largest glitch ever observed in this source. Due to our high-cadence and long-dwell time observations of the Crab pulsar we are able to partially resolve a fraction of the total spin-up of the star. This delayed spin-up occurred over a timescale of ˜1.7 days and is similar to the behaviour seen in the 1989 and 1996 large Crab pulsar glitches. The spin-down rate also increased at the glitch epoch by Δ \\dot{ν } / \\dot{ν } = 7 × 10^{-3}. In addition to being the largest such event observed in the Crab, the glitch occurred after the longest period of glitch inactivity since at least 1984 and we discuss a possible relationship between glitch size and waiting time. No changes to the shape of the pulse profile were observed near the glitch epoch at 610 MHz or 1520 MHz, nor did we identify any changes in the X-ray flux from the pulsar. The long-term recovery from the glitch continues to progress as \\dot{ν } slowly rises towards pre-glitch values. In line with other large Crab glitches, we expect there to be a persistent change to \\dot{ν }. We continue to monitor the long-term recovery with frequent, high quality observations.

    To explore perspectives of health care professionals and female Somali and Bangladeshi Muslim women on practices related to fasting during Ramadan, the impact of fasting on health and the role of health professionals during Ramadan. A cross-sectional qualitative study was conducted. Two culturally specific focus groups were conducted with six Somali and seven Bangladeshi Muslim women who observed Ramadan and lived in an inner-city neighbourhood of Toronto, Canada. Individual semi-structured interviews were conducted with 22 health care professionals practicing in this inner-city area (three of whom were Muslim). Data were analysed using thematic qualitative analysis. Both Muslim women and health care professionals recognised the spiritual significance of the Ramadan fast. Muslim participants considered the fast to be beneficial to health overall, whereas health care professionals tended to reflect on health concerns from fasting. Many health care professionals were not fully aware of fasting practices during Ramadan and some found it challenging to counsel patients about the health effects of fasting. Muslim women expressed disagreement regarding which medical interventions were permitted during fasting. They generally agreed that health care professionals should not specifically advise against fasting, but instead provide guidance on health maintenance while fasting. Both groups agreed that guidelines developed by the health care and faith communities together would be useful. There are a variety of health beliefs and observances among female Muslim Somali and Bangladeshi women and a range of knowledge, experience and opinions among health care professionals related to fasting during Ramadan and health. Overall, there is a need for improved communication between members of the Muslim community and health professionals in Canada about health issues related to fasting during Ramadan. Strategies could include published practice guidelines endorsed by the Muslim

    2009-09-01

    Europe's offshore wind potential is enormous and able to power Europe seven times over. Over 100 GW of offshore wind projects are already in various stages of planning. If realised, these projects would produce 10% of the EU's electricity whilst avoiding 200 million tonnes of CO2 emissions each year. EWEA has a target of 40 GW of offshore wind in the EU by 2020, implying an average annual market growth of 28% over the coming 12 years. The EU market for onshore wind grew by an average 32% per year in the 12-year period from 1992-2004 - what the wind energy industry has achieved on land can be repeated at sea. EWEA's proposed offshore grid builds on the 11 offshore grids currently operating and 21 offshore grids currently being considered by the grid operators in the Baltic and North Seas to give Europe a truly pan-European electricity super highway. Strong political support and action from Europe's policy-makers will allow a new, multi-billion euro industry to be built. This new industry will deliver thousands of green collar jobs and a new renewable energy economy and establish Europe as world leader in offshore wind power technology. A single European electricity market with large amounts of wind power will bring affordable electricity to consumers, reduce import dependence, cut CO2 emissions and allow Europe to access its largest domestic energy source.

  19. Characterization of the largest effector gene cluster of Ustilago maydis.

    2014-07-01

    Full Text Available In the genome of the biotrophic plant pathogen Ustilago maydis, many of the genes coding for secreted protein effectors modulating virulence are arranged in gene clusters. The vast majority of these genes encode novel proteins whose expression is coupled to plant colonization. The largest of these gene clusters, cluster 19A, encodes 24 secreted effectors. Deletion of the entire cluster results in severe attenuation of virulence. Here we present the functional analysis of this genomic region. We show that a 19A deletion mutant behaves like an endophyte, i.e. is still able to colonize plants and complete the infection cycle. However, tumors, the most conspicuous symptoms of maize smut disease, are only rarely formed and fungal biomass in infected tissue is significantly reduced. The generation and analysis of strains carrying sub-deletions identified several genes significantly contributing to tumor formation after seedling infection. Another of the effectors could be linked specifically to anthocyanin induction in the infected tissue. As the individual contributions of these genes to tumor formation were small, we studied the response of maize plants to the whole cluster mutant as well as to several individual mutants by array analysis. This revealed distinct plant responses, demonstrating that the respective effectors have discrete plant targets. We propose that the analysis of plant responses to effector mutant strains that lack a strong virulence phenotype may be a general way to visualize differences in effector function.

    El Paso Natural Gas Co.'s largest expansion program in its 64-year history will be completed along its northern system this spring or early summer. According to the company, the three-tiered, $241.5 million expansion program will increase El Paso's gas-transport capacity by 835 MMcfd to 2.5 bcfd of conventional and coal-seam gas from the San Juan basin in northwestern New Mexico. That's enough natural gas, says the company, to supply the needs of a city of more than 800,000 residents. This paper reports that the expansion involves the San Juan Triangle system, the company's northern main line, and the Permian-San Juan crossover line. The company also filed with the Federal Energy Regulatory Commission (FERC) in October 1991 to construct a new $15.2 million compressor station, Rio Vista, south of Bloomfield, N.M. The station would be used to move additional gas to the main line

    To evaluate wrought titanium aluminide (gamma TiAl) as a viable candidate material for the High-Speed Civil Transport (HSCT) exhaust nozzle, an international team led by the NASA Glenn Research Center at Lewis Field successfully fabricated and tested the largest gamma TiAl sheet structure ever manufactured. The gamma TiAl sheet structure, a 56-percent subscale divergent flap subelement, was fabricated for benchmark testing in three-point bending. Overall, the subelement was 84-cm (33-in.) long by 13-cm (5-in.) wide by 8-cm (3-in.) deep. Incorporated into the subelement were features that might be used in the fabrication of a full-scale divergent flap. These features include the use of: (1) gamma TiAl shear clips to join together sections of corrugations, (2) multiple gamma TiAl face sheets, (3) double hot-formed gamma TiAl corrugations, and (4) brazed joints. The structural integrity of the gamma TiAl sheet subelement was evaluated by conducting a room-temperature three-point static bend test.

    2018-04-01

    Eutrophication is a major water quality issue in lakes worldwide and is principally caused by the loadings of phosphorus from catchment areas. It follows that to develop strategies to mitigate eutrophication, we must have a good understanding of the amount, sources, and trends of phosphorus pollution. This paper provides the first consistent and harmonious estimates of current phosphorus loadings to the world's largest 100 lakes, along with the sources of these loadings and their trends. These estimates provide a perspective on the extent of lake eutrophication worldwide, as well as potential input to the evaluation and management of eutrophication in these lakes. We take a modeling approach and apply the WorldQual model for these estimates. The advantage of this approach is that it allows us to fill in large gaps in observational data. From the analysis, we find that about 66 of the 100 lakes are located in developing countries and their catchments have a much larger average phosphorus yield than the lake catchments in developed countries (11.1 versus 0.7 kg TP km-2 year-1). Second, the main source of phosphorus to the examined lakes is inorganic fertilizer (47% of total). Third, between 2005-2010 and 1990-1994, phosphorus pollution increased at 50 out of 100 lakes. Sixty percent of lakes with increasing pollution are in developing countries. P pollution changed primarily due to changing P fertilizer use. In conclusion, we show that the risk of P-stimulated eutrophication is higher in developing countries.

    When it switches on in 2008, the 26.7 km Large Hadron Collider (LHC) at CERN, will have the world's largest vacuum system operating over a wide range of pressures and employing an impressive array of vacuum technologies. This system is composed by 54 km of UHV vacuum for the circulating beams and 50 km of insulation vacuum around the cryogenic magnets and the liquid helium transfer lines. Over the 54 km of UHV beam vacuum, 48 km of this are at cryogenic temperature (1.9 K). The remaining 6 km of beam vacuum containing the insertions for "cleaning" the proton beams, radiofrequency cavities for accelerating the protons as well as beam-monitoring equipment is at ambient temperature and uses non-evaporable getter (NEG) coatings - a vacuum technology that was born and industrialized at CERN. The pumping scheme is completed using 780 ion pumps to remove noble gases and to provide pressure interlocks to the 303 vacuum safety valves. Pressure readings are provided by 170 Bayard-Alpert gauges and 1084 gauges (Pirani a...

  5. When clusters collide: constraints on antimatter on the largest scales

    International Nuclear Information System (INIS)

    Steigman, Gary

    2008-01-01

    Observations have ruled out the presence of significant amounts of antimatter in the Universe on scales ranging from the solar system, to the Galaxy, to groups and clusters of galaxies, and even to distances comparable to the scale of the present horizon. Except for the model-dependent constraints on the largest scales, the most significant upper limits to diffuse antimatter in the Universe are those on the ∼Mpc scale of clusters of galaxies provided by the EGRET upper bounds to annihilation gamma rays from galaxy clusters whose intracluster gas is revealed through its x-ray emission. On the scale of individual clusters of galaxies the upper bounds to the fraction of mixed matter and antimatter for the 55 clusters from a flux-limited x-ray survey range from 5 × 10 −9 to −6 , strongly suggesting that individual clusters of galaxies are made entirely of matter or of antimatter. X-ray and gamma-ray observations of colliding clusters of galaxies, such as the Bullet Cluster, permit these constraints to be extended to even larger scales. If the observations of the Bullet Cluster, where the upper bound to the antimatter fraction is found to be −6 , can be generalized to other colliding clusters of galaxies, cosmologically significant amounts of antimatter will be excluded on scales of order ∼20 Mpc (M∼5×10 15 M sun )

    The camel is a multipurpose animal with a huge productive potential. Camel milk is a key food in arid and semi-arid areas of the African and Asian countries. The quality of milk is influenced by different bacteria present in milk. This study was conducted to evaluate total bacterial content in raw camel milk along the market chain in Fafen zone, Ethiopian Somali Regional State. One hundred twenty-six raw camel milk samples were collected from Gursum (47.1 %) and Babile (52.9 %) districts. The three sampling levels included were udder (14.7 %), milking bucket (29.4 %) and market (55.9 %). Milk samples were analyzed for total bacterial counts (TBC) and coliform counts (CC). Furthermore, major pathogens were isolated and identified. 108 (85.7 %) of raw camel milk samples demonstrated bacterial contamination. The overall mean TBC and CC of contaminated raw camel milk samples was 4.75 ± 0.17 and 4.03 ± 0.26 log CFU/ml, respectively. TBC increased from udder to market level and was higher in Gursum compared to Babile district (P < 0.05). Around 38.9 % of TBCs and 88.2 % CCs in contaminated raw camel milk samples were in the range considered unsafe for human utility. Staphylococcus spp. (89.8 %), Streptococcus spp. (53.7 %), E. coli (31.5 %), Salmonella spp. (17.6 %), Klebsiella spp. (5.6 %) and Enterobacter spp. (5.6 %) were the major bacterial microorganisms isolated. The majority of the bacterial isolates in this study showed high incidence in market as compared to production level. These results indicate a lack of compliance with good production practices and hygiene at milking, transportation and market of raw camel milk.

    Recent increases in ivory poaching have depressed African elephant populations. Successful enforcement has led to ivory being stockpiled. Stockpile destruction is becoming increasingly popular, and most destruction has occurred in the last five years. Ivory destruction is intended to send a strong message against ivory consumption, both in promoting a taboo on ivory use and catalyzing policy change. However, there has been no effort to establish the distribution and extent of media reporting on ivory destruction events globally. We analyze media coverage across eleven important nation states of the largest ivory destruction event in history (Kenya, 30 April 2016). We used a well-accepted online media crawling tool and key language translations to search online and print newspapers. We found most online news on the ivory burn came from the US (81% of articles), while print news was dominated by Kenya (61% of articles). We subjected online articles from five key countries and territories to content analysis and found 86-97% of all online articles reported the burn as a positive conservation action, while between 4-50% discussed ivory burning as having a negative impact on elephant conservation. Most articles discussed law enforcement and trade bans as effective for elephant conservation. There was more relative search interest globally on the 2016 Kenyan ivory burn than any other in five years. Our study is the first attempt to track the spread of media around an ivory burn and is a case study in tracking the effects of a conservation-marketing event. This article is protected by copyright.

    Rust fungi (Basidiomycota, Pucciniales) are biotrophic plant pathogens which exhibit diverse complexities in their life cycles and host ranges. The completion of genome sequencing of a few rust fungi has revealed the occurrence of large genomes. Sequencing efforts for other rust fungi have been hampered by uncertainty concerning their genome sizes. Flow cytometry was recently applied to estimate the genome size of a few rust fungi, and confirmed the occurrence of large genomes in this order (averaging 225.3 Mbp, while the average for Basidiomycota was 49.9 Mbp and was 37.7 Mbp for all fungi). In this work, we have used an innovative and simple approach to simultaneously isolate nuclei from the rust and its host plant in order to estimate the genome size of 30 rust species by flow cytometry. Genome sizes varied over 10-fold, from 70 to 893 Mbp, with an average genome size value of 380.2 Mbp. Compared to the genome sizes of over 1800 fungi, Gymnosporangium confusum possesses the largest fungal genome ever reported (893.2 Mbp). Moreover, even the smallest rust genome determined in this study is larger than the vast majority of fungal genomes (94%). The average genome size of the Pucciniales is now of 305.5 Mbp, while the average Basidiomycota genome size has shifted to 70.4 Mbp and the average for all fungi reached 44.2 Mbp. Despite the fact that no correlation could be drawn between the genome sizes, the phylogenomics or the life cycle of rust fungi, it is interesting to note that rusts with Fabaceae hosts present genomes clearly larger than those with Poaceae hosts. Although this study comprises only a small fraction of the more than 7000 rust species described, it seems already evident that the Pucciniales represent a group where genome size expansion could be a common characteristic. This is in sharp contrast to sister taxa, placing this order in a relevant position in fungal genomics research.

  9. GIS learning tool for world's largest earthquakes and their causes

    Science.gov (United States)

    Chatterjee, Moumita

    The objective of this thesis is to increase awareness about earthquakes among people, especially young students by showing the five largest and two most predictable earthquake locations in the world and their plate tectonic settings. This is a geographic based interactive tool which could be used for learning about the cause of great earthquakes in the past and the safest places on the earth in order to avoid direct effect of earthquakes. This approach provides an effective way of learning for the students as it is very user friendly and more aligned to the interests of the younger generation. In this tool the user can click on the various points located on the world map which will open a picture and link to the webpage for that point, showing detailed information of the earthquake history of that place including magnitude of quake, year of past quakes and the plate tectonic settings that made this place earthquake prone. Apart from knowing the earthquake related information students will also be able to customize the tool to suit their needs or interests. Students will be able to add/remove layers, measure distance between any two points on the map, select any place on the map and know more information for that place, create a layer from this set to do a detail analysis, run a query, change display settings, etc. At the end of this tool the user has to go through the earthquake safely guidelines in order to be safe during an earthquake. This tool uses Java as programming language and uses Map Objects Java Edition (MOJO) provided by ESRI. This tool is developed for educational purpose and hence its interface has been kept simple and easy to use so that students can gain maximum knowledge through it instead of having a hard time to install it. There are lots of details to explore which can help more about what a GIS based tool is capable of. Only thing needed to run this tool is latest JAVA edition installed in their machine. This approach makes study more fun and

    The author has identified the following significant results. ERTS-1 MSS imagery covering the Afar-Triangle/Ethiopia and adjacent regions (Ethiopian Plateau, Somali Plateau, and parts of Yemen and Saudi Arabi) was applied to the mapping of lithologic and structural units of the test area at a scale 1:1,000,000. Results of the geological evaluation of the ERTS-1 imagery of the Afar have proven the usefullness of this type of satellite data for regional geological mapping. Evaluation of the ERTS images also resulted in new aspects of the structural setting and tectonic development of the Afar-Triangle, where three large rift systems, the oceanic rifts of the Red Sea and Gulf of Aden and the continental East African rift system, seem to meet each other. Surface structures mapped by ERTS do not indicate that the oceanic rift of the Gulf of Aden (Sheba Ridge) continues into the area of continental crust west of the Gulf of Tadjura. ERTS data show that the Wonji fault belt of the African rift system does not enter or cut through the central Afar. The Aysha-Horst is not a Horst but an autochthonous spur of the Somali Plateau.

    The study was conducted to determine the effects of dried foliage of Acacia senegal and Neem (Azadirachta indica) tree supplementations on feed intake, nutrient digestibility, growth, and carcass parameters in short-eared Somali goats. Twenty male intact short-eared Somali goat yearlings with an average live weight of 16.2 ± 1.08 (Mean ± SD) were assigned to four treatment groups, which comprised a basal diet of hay alone (T1) and supplementation with the tree foliages. Supplements consisted Neem tree (T2), A. senegal (T3) and the mixture of the two (1:1 ratio; T4) dried foliages. The crude protein (CP) content of Neem tree foliage, A. senegal, and their mixture were 16.92, 17.5 and 17.01 % of dry matter (DM), respectively. Total DM intake and digestibility of DM and organic matter were significantly (P senegal (67 %). The final body weights were higher (P Senegal. An average daily body weight (BW) gain was higher (P senegal (8.3 kg) among the supplemented groups, all of which are higher than the control (4.9 kg). It is concluded that the supplementation with tree foliage, especially with A. senegal tree foliage, on grass hay encouraged a better utilization of nutrients and animal performance as compared to goats fed on a basal diet of grass hay only.

    In the framework of cooperation for development projects in Burkina Faso and Ethiopia, we collected ixodid ticks from cattle, small ruminants and camels. We optimized new TaqMan Probe real-time PCR assays to detect Rickettsia aeschlimannii and Rickettsia africae OmpA gene in the collected samples. Rickettsia africae was identified in 75.0% Amblyomma variegatum (95%CI: 56.6-88.5), while R. aeschlimannii in 24.0% Hyalomma truncatum (95%CI: 9.4-45.1) and 50.0% H. rufipes (95%CI: 29.9-70.0) collected from cattle in different provinces throughout Burkina Faso. Ticks from the Libaan zone, Somali Region of Ethiopia, were also infected by R. africae (28.5% prevalence in Amblyomma gemma, 95%CI: 14.7-46.0) and R. aeschlimannii (27.0% H. truncatum, 95%CI: 5.0-62.9; 88.3% H. rufipes, 95%CI: 60.5-99.3). All tested ticks were adults. The developed diagnostic tools were highly sensitive and enabled us to rapidly classify R. aeschlimannii and R. africae, which were identified in Burkina Faso and in the Somali Region of Ethiopia for the first time. Further studies are needed to assess the zoonotic risk and prevalence of infection in local human populations, who have high contact rates with ticks and their animal hosts.

    2001-01-01

    The new Diamond Valley Lake Reservoir near the city of Hemet in Riverside County is billed as the largest earthworks construction project in U.S.history. Construction began in 1995 and involved 31 million cubic meters of foundation excavation and 84 million cubic meters of embankment construction. This set of MISR images captures the most recent phase in the reservoir's activation. At the upper left is a natural-color view acquired by the instrument's vertical-viewing (nadir) camera on March 14, 2000 (Terra orbit 1273), shortly after the Metropolitan Water District began filling the reservoir with water from the Colorado River and Northern California. Water appears darker than the surrounding land. The image at the upper right was acquired nearly one year later on March 1, 2001 (Terra orbit 6399), and shows a clear increase in the reservoir's water content. When full, the lake will hold nearly a trillion liters of water.According to the Metropolitan Water District, the 7 kilometer x 3 kilometer reservoir nearly doubles Southern California's above-groundwater storage capacity. In addition to routine water management, Diamond Valley Lake is designed to provide protection against drought and a six-month emergency supply in the event of earthquake damage to a major aqueduct. In the face of electrical power shortages, it is also expected to reduce dependence on the pumping of water from northern mountains during the high-demand summer months. An unexpected result of site excavation was the uncovering of mastodon and mammoth skeletons along with bones from extinct species not previously thought to have been indigenous to the area, such as the giant long-horned bison and North American lion. A museum and interpretive center is being built to protect these finds.The lower MISR image, from May 20, 2001 (Terra orbit 7564), is a false-color view combining data from the instrument's 26-degree forward view (displayed as blue) with data from the 26-degree backward view

    The fact that surprising new discoveries can be made in layered mafic intrusions (e.g., subtle 100-150 m cyclicity in apparently homogeneous cumulates over 1000s of m) means that we are still in the first-order characterization phase of understanding these objects. Accordingly, we have secured funding from ICDP for a planning workshop to be held in Johannesburg in early 2014, aimed at scientific drilling of the Bushveld Complex, the world's largest layered mafic intrusion. Science objectives include, but are not limited to: 1. Magma chamber processes & melt evolution. How many melts/magmas/mushes were involved, what were their compositions and how did they interact? What, if anything, is missing from the Complex, and where did it go? Did Bushveld magmatism have an effect upon Earth's atmosphere at 2 Ga? 2. Crust-mantle interactions & origin of Bushveld granitoids. Are Bushveld granites & rhyolites crustal melts, differentiates from the mafic magmas or products of immiscibility? How can the evolved isotopic signatures in the mafic rocks (e.g., epsilon Nd to -8) be understood? 3. Origin of ore deposits. What were the relative roles of gravity settling, magma mixing, immiscibility and hydrothermal fluid transport in producing the PGE, Cr and V deposits? We have identified 3 potential drilling targets representing a total of ~12 km of drill core. Exact locations of drill sites are to be discussed at the workshop. Target A- East-Central Bushveld Complex. We propose 3 overlapping 3 km boreholes that will provide the first roof-to-floor continuous coverage of the Rustenburg Layered Suite. These boreholes will represent a curated, internationally available reference collection of Bushveld material for present and future research. Target B- Southeastern Bushveld Complex. We propose a single borehole of ~2 km depth, collared in Rooiberg felsite, and positioned to intersect the Roof Zone, Upper Zone, Main Zone and floor of the Complex. Amongst other things, this site will

    2006-01-01

    To assist the United States Department of Energy's (US DOE's) re-industrialization efforts at its gaseous diffusion site in Oak Ridge, Tennessee, known as the East Tennessee Technology Park (ETTP), the US DOE awarded a 6-year Decontamination and Decommissioning (D and D) contract to BNG America (formerly BNFL Inc.) in 1997. The ETTP 3-Building D and D Project included the removal and disposition of the materials and equipment from the K-33, K-31, and K-29 Gaseous Diffusion Plant buildings. The three buildings comprise more than 4.8 million square feet (446,000 square meters) of floor surface area and more than 350 million pounds (148 million kilograms) of hazardous and radioactively contaminated material, making it the largest nuclear D and D project in progress anywhere in the world. The logistical hurdles involved in a project of this scope and magnitude required an extensive amount of Engineering and Health Physics professionals. In order to accomplish the Final Status Survey (FSS) for a project of this scope, the speed and efficiency of automated survey equipment was essential. Surveys of floors, structural steel and ceilings up to 60 feet (18 meters) were required. The FSS had to be expanded to include additional remediation and surveys due to characterization surveys and assumptions regarding the nature and extent of contamination provided by the US DOE. Survey design and technical bases had to consider highly variable constituents; including uranium from depleted to low enrichment, variable levels of Technetium-99 and transuranic nuclides, which were introduced into the cascade during the 1960's when recycled uranium (RU) from Savannah River was re-enriched at the facility. The RU was transported to unexpected locations from leaks in the cascade by complex building ventilation patterns. The primary survey tool used for the post remediation and FSS was the Surface Contamination Monitor (SCM) and the associated Survey Information Management System (SIMS

    Full Text Available The objectives of this paper were to identify and describe husbandry practices, herd structure, owners’ trait preferences, breeding practices, and production constraints of camel in the two major camel rearing pastoral communities, viz. Afar and Somali, to generate baseline information that would help to plan possible breed improvement strategies and options for the different camel populations. The study sites were selected purposively while households from each of the sites randomly. Data were collected using formal questionnaires and focus group discussion. Results showed that average camel population per household was higher in Mille (28.06±2.27, Gode (27.51±2.02, and Moyale (24.07±2.13 districts. Female camel populations with age of >1 year contributes 78-83% of the total camel herd population in all the study districts. Higher number of female animals in the herd in the arid environment means providing continuous supply of milk and allows a rapid recovery of herd numbers after a disease outbreak or drought occurrence. This shows that pastoralists breeding objectives are in relation to the arid environment and female population in the herd. Most of the pastoral communities utilize a single breeding male camel per 40-50 female camels and this will affect productivity and heterogeneity of camel population. With regard to trait preference, all pastoral communities ranked milk yield as the first trait of choice, except Liben district in which adaptation trait was the primary preference. Growth trait ranked second in Mille, Gode, Liben, and Jijiga pastoral communities where as adaptation trait ranked second in Amibara and Shinille pastoral communities. The major camel production constraints were feed, diseases, and lack of water in that order and the major cause of the constraints was the recurrent drought occurred during the past 2-3 decades in the two regions. Therefore, in planning and implementation of the breeding strategies for small

    Full Text Available Abstract A pessimistic view of the impact of armed conflicts on the control of infectious diseases has generated great interest in the role of conflicts on the global TB epidemic. Nowhere in the world is such interest more palpable than in the Horn of Africa Region, comprising Ethiopia, Somalia, Eritrea, Djibouti, Kenya and Sudan. An expanding literature has demonstrated that armed conflicts stall disease control programs through distraction of health system, interruption of patients' ability to seek health care, and the diversion of economic resources to military ends rather than health needs. Nonetheless, until very recently, no research has been done to address the impact of armed conflict on TB epidemics in the Somali Regional State (SRS of Ethiopia. Methods This study is based on the cross-sectional data collected in 2007, utilizing structured questionnaires filled-out by a sample of 226 TB patients in the SRS of Ethiopia. Data was obtained on the delay patients experienced in receiving a diagnosis of TB, on the biomedical knowledge of TB that patients had, and the level of self-treatment by patients. The outcome variables in this study are the delay in the diagnosis of TB experienced by patients, and extent of self-treatment utilized by patients. Our main explanatory variable was place of residence, which was dichotomized as being in 'conflict zones' and in 'non-conflict zones'. Demographic data was collected for statistical control. Chi-square and Mann-Whitney tests were used on calculations of group differences. Logistic regression analysis was used to determine the association between outcome and predictor variables. Results Two hundred and twenty six TB patients were interviewed. The median delay in the diagnosis of TB was 120 days and 60 days for patients from conflict zones and from non-conflict zones, respectively. Moreover, 74% of the patients residing in conflict zones undertook self-treatment prior to their diagnosis. The

    Kobe Refugee camp hosts roughly 39,000 refugees displaced from Somalia during the 2011-2012 Horn of Africa Crisis. Sexual and reproductive health, as with the greater issues of health and well-being for adolescents displaced from this crisis remain largely unknown and neglected. In 2013, the Women's Refugee Commission, Johns Hopkins University, and International Medical Corps in Ethiopia, implemented qualitative and quantitative research to explore the factors and risks that impact the health of very young adolescents (VYAs), those 10-14 years of age, in this setting. This paper presents findings from the qualitative effort. Focus group discussions (FGD), incorporating community mapping and photo elicitation activities, were conducted with 10-12 and 13-14 year-olds to obtain information about their own perspectives, experiences and values. FGDs were also implemented with 15-16 year-olds and adults, to consider their perspectives on the sexual and reproductive health needs and risks of VYAs. This research identified several factors that were found to influence the health and well-being of VYAs in Kobe refugee camp, including newfound access to education and security, combined with gender divisions and parental communication around early SRH and puberty that remained intact from traditional Somali culture. Girls were found to face an additional risk of child marriage and early pregnancy exacerbated since displacement, which significantly limited their ability to access education and achieve future aspirations. Findings from this study could help to inform future programs in Kobe and similar contexts involving long-term displacement from conflict, focusing on the health and development needs of VYAs. Future programs should consider the determinants of positive VYA health and development, including access to education, gender equity, and safety.By better understanding the unique experiences, perspectives and needs of VYAs, practitioners, policy makers and donors can

  1. Is female circumcision evolving or dissolving in Norway? A qualitative study on attitudes toward the practice among young Somalis in the Oslo area.

    2015-01-01

    Female genital mutilation or female circumcision (FC) is increasingly visible on the global health and development agenda - both as a matter of social justice and equality for women and as a research priority. Norway is one of the global nations hosting a large number of immigrants from FC-practicing countries, the majority from Somalia. To help counteract this practice, Norway has adopted a multifaceted policy approach that employs one of the toughest measures against FC in the world. However, little is known about the impact of Norway's approach on the attitudes toward the practice among traditional FC-practicing communities in Norway. Against this background, this qualitative study explores the attitudes toward FC among young Somalis between the ages of 16 to 22 living in the Oslo and Akershus regions of Norway. Findings indicate that young Somalis in the Oslo area have, to a large extent, changed their attitude toward the practice. This was shown by the participants' support and sympathy toward criminalization of FC in Norway, which they believed was an important step toward saving young girls from the harmful consequences of FC. Most of the uncircumcised girls see their uncircumcised status as being normal, whereas they see circumcised girls as survivors of violence and injustice. Moreover, the fact that male participants prefer a marriage to uncircumcised girls is a strong condition for change, since if uncut girls are seen as marriageable then parents are unlikely to want to circumcise them. As newly arrived immigrants continue to have positive attitudes toward the practice, knowledge of FC should be integrated into introduction program classes that immigrants attend shortly after their residence permit is granted. This study adds to the knowledge of the process of the abandonment of FC among immigrants in Western countries.

  2. Along-dip variations of structural style in the Somali Basin deep-water fold and thrust belt (East Africa)

    Continental passive margins are place of extended slope-failure phenomena, which can lead to the formation of gravity-driven deep-water fold and thrust belts (DW-FTBs), in regions where no far-field compressional stress is active. These giant geological features, which are confined to the sedimentary section, consist of extensional-compressional linked systems detached over a common décollement, generally salt or shales. The continental passive margin of northern Kenya and southern Somalia is an excellent and relatively unexplored site for recognizing and understanding the DW-FTBs originated over a regional shale décollement. In this study we have interpreted a 2D seismic data-set of the 1980s, hosted by Marine Geoscience Data System at Lamont-Doherty Earth Observatory of Columbia University (http://www.marine-geo.org), and recently reprocessed by ENI, in order to investigate the structural style of a DW-FTB developed offshore of northern Kenya and southern Somalia (Somali Basin). This region records the oldest sedimentary section of the Indian Ocean since the breakup of Gondwana began in the Middle-Lower Jurassic separating Madagascar from Africa. From the Upper Cretaceous to at least the Lower Miocene, the margin has been characterized by gravitational collapse leading to the formation of a DW-FTB extending more than 400 km along-strike. The northern portion of the DW-FTB is about 150 km wide, whilst in the southern portion is few tens of km wide. We analysed the northern portion along a regional seismic section. Our study represents the first detailed structural interpretation of this DW-FTB since its discovery in the 1980s. The good quality of the available reprocessed seismic data has allowed us to identify remarkable along-dip variations in the structural style. The basal detachment constantly deepens landward, in agreement with a prevailing gravity-spreading deformation process (as in the case of the Niger Delta). On the seismic data are not visible, as

    The aim of the study is to elucidate young women's perceptions of the situation for female survivors of non-partner sexual violence in Somaliland. Young Somali women with diverse backgrounds (n = 25) shared views, knowledge and opinions about non partner sexual violence in focus group discussions held in urban settings. Data was analysed using content analysis. A main category "Bound by culture and community perceptions" with four subcategories comprises the informants' perceptions of non-partner sexual violence among young women in Somaliland. Illuminated is the importance of protecting oneself and the family dignity, a fear of being rejected and mistrusted, how the juridical system exists in the shadow of tradition and potential keys to healthcare support. The study raises awareness of the dilemmas which may be faced by young women subjected to non-partner sexual violence and healthcare providers in the intersection between state and traditional norms. Education is a key when it comes to a young woman considering the use of the services available in a society where traditional problem-solving is relied on parallel to state-based support. State-based functions, communities and families need to work together to provide comprehensive support to young female survivors of non-partner sexual violence in Somaliland.

    Full Text Available The aim of this study was to develop, test, and evaluate a 24-h recall procedure to assess the dietary intake of toddlers of Somali- and Iraqi-born mothers living in Norway. A protocol for a 24-h multiple-pass recall procedure, registration forms, and visual tools (a picture library for food identification and portion size estimation was developed and tested in 12 mothers from Somalia and Iraq with children aged 10–21 months. Five female field workers were recruited and trained to conduct the interviews. Evaluation data for the 24-h recall procedure were collected from both the mothers and the field workers. Nutrient intake was calculated using a Norwegian dietary calculation system. Each child’s estimated energy intake was compared with its estimated energy requirement. Both the mothers and the field workers found the method feasible and the visual tools useful. The estimated energy intake corresponded well with the estimated energy requirement for most of the children (within mean ± 2 SD, except for three. The pilot study identified the need for additional foods in the picture library and some crucial aspects in training and supervising the field workers to reduce sources of error in the data collection.

  12. The Multivariate Largest Lyapunov Exponent as an Age-Related Metric of Quiet Standing Balance

    2015-01-01

    Full Text Available The largest Lyapunov exponent has been researched as a metric of the balance ability during human quiet standing. However, the sensitivity and accuracy of this measurement method are not good enough for clinical use. The present research proposes a metric of the human body’s standing balance ability based on the multivariate largest Lyapunov exponent which can quantify the human standing balance. The dynamic multivariate time series of ankle, knee, and hip were measured by multiple electrical goniometers. Thirty-six normal people of different ages participated in the test. With acquired data, the multivariate largest Lyapunov exponent was calculated. Finally, the results of the proposed approach were analysed and compared with the traditional method, for which the largest Lyapunov exponent and power spectral density from the centre of pressure were also calculated. The following conclusions can be obtained. The multivariate largest Lyapunov exponent has a higher degree of differentiation in differentiating balance in eyes-closed conditions. The MLLE value reflects the overall coordination between multisegment movements. Individuals of different ages can be distinguished by their MLLE values. The standing stability of human is reduced with the increment of age.

    Identifying the nodes with largest spreading influence of complex networks is one of the most promising domains. By taking into account the neighbors' k-core values, we present an improved neighbors' k-core (INK) method which is the sum of the neighbors' k-core values with a tunable parameter α to evaluate the node spreading influence with largest k-core values. Comparing with the Susceptible–Infected–Recovered (SIR) results for four real networks, the INK method could identify the node spreading influence with largest k-core values more accurately than the ones generated by the degree k, closeness C, betweenness B and coreness centrality method. - Highlights: • We present an improved neighbors' k-core (INK) method to evaluate the node spreading influence with largest k-core values. • The INK method could identify the node spreading influence with largest k-core values more accurately. • Kendall's tau τ of INK method with α=1 are highly identical to rank the node influence

    Following a rapid influx of over 200,000 displaced Somalis into the Dadaab refugee camp complex in Kenya, Médecins Sans Frontières conducted a mortality and nutrition survey of the population living in Bulo Bacte, a self-settled area surrounding Dagahaley camp (part of this complex). The survey was conducted between 31st July and 10th August 2011. We exhaustively interviewed representatives from all households in Bulo Bacte, collecting information on deaths, births, and population movements during the recall period (15th February 2011 to survey date), in order to provide estimates of retrospective death rates. We recorded the mid-upper arm circumference and presence or absence of bipedal oedema of all children of height 67-global and severe acute malnutrition. The surveyed population included 26,583 individuals, of whom 6,488 (24.4%) were children aged under 5 years. There were 360 deaths reported during the 177 days of the recall period, of which 186 (52%) were among children aged under 5 years. The crude death rate for the entire recall period was 0.8 per 10,000 person-days. The under-5 death rate was 1.8 per 10,000 person-days. More than two-thirds of all deaths were reported to have been associated with diarrhoea (25%), cough or other breathing difficulties (24%), or with fever (19%). Measles accounted for a reported 17% of all deaths; this was due to a measles outbreak that occurred between June and October 2011.Global acute malnutrition was observed in 13.4%, and severe acute malnutrition in 3.0%, of children measuring 67-crisis-affected populations should be revised to take into account the epidemiologic context. Organisations must be sensitive and reactive to changes in the health status of the populations they assist.

    More than 41,000 spider species are known with about 400-500 added each year, but for some well-known groups, such as the giant golden orbweavers, Nephila, the last valid described species dates from the 19(th) century. Nephila are renowned for being the largest web-spinning spiders, making the largest orb webs, and are model organisms for the study of extreme sexual size dimorphism (SSD) and sexual biology. Here, we report on the discovery of a new, giant Nephila species from Africa and Madagascar, and review size evolution and SSD in Nephilidae. We formally describe N. komaci sp. nov., the largest web spinning species known, and place the species in phylogenetic context to reconstruct the evolution of mean size (via squared change parsimony). We then test female and male mean size correlation using phylogenetically independent contrasts, and simulate nephilid body size evolution using Monte Carlo statistics. Nephila females increased in size almost monotonically to establish a mostly African clade of true giants. In contrast, Nephila male size is effectively decoupled and hovers around values roughly one fifth of female size. Although N. komaci females are the largest Nephila yet discovered, the males are also large and thus their SSD is not exceptional.

    Full Text Available The dynamics of network traffic are complex and nonlinear, and chaotic behaviors and their prediction, which play an important role in local area networks (LANs, are studied in detail, using the largest Lyapunov exponent. With the introduction of phase space reconstruction based on the time sequence, the high-dimensional traffic is projected onto the low dimension reconstructed phase space, and a reduced dynamic system is obtained from the dynamic system viewpoint. Then, a numerical method for computing the largest Lyapunov exponent of the low-dimensional dynamic system is presented. Further, the longest predictable time, which is related to chaotic behaviors in the system, is studied using the largest Lyapunov exponent, and the Wolf method is used to predict the evolution of the traffic in a local area network by both Dot and Interval predictions, and a reliable result is obtained by the presented method. As the conclusion, the results show that the largest Lyapunov exponent can be used to describe the sensitivity of the trajectory in the reconstructed phase space to the initial values. Moreover, Dot Prediction can effectively predict the flow burst. The numerical simulation also shows that the presented method is feasible and efficient for predicting the complex dynamic behaviors in LAN traffic, especially for congestion and attack in networks, which are the main two complex phenomena behaving as chaos in networks.

    Japan is the third largest oil consumer in the world behind the United States and China, and the second largest net importer of oil. Japan boasts one of the largest economies in the world. The country continues to experience a moderate economic recovery that began in 2003, following a decade of economic stagnation. Japan's real gross domestic product (GDP) grew by 2.5% in 2005 and 2.3% in 2004. The modest upturn over the last few years reflects higher business confidence in Japan, a surge in export demand led by exports to China, and robust consumer spending. Unemployment in Japan fell to 4.4% in 2005, down from an early 2003 peak of 5.5%. Japan has virtually no domestic oil or natural gas reserves, and in 2005 was the second largest net importer of crude oil in the world. Despite the country's dearth of hydrocarbon resources, Japanese companies have actively pursued upstream oil and natural gas projects overseas. Japan remains one of the major exporters of energy-sector capital equipment, and Japanese companies provide engineering, construction, and project management services for energy projects. (orig.)

    Full Text Available Abstract Background Bovine follicular development is regulated by numerous molecular mechanisms and biological pathways. In this study, we tried to identify differentially expressed genes between largest (F1 and second-largest follicles (F2, and classify them by global gene expression profiling using a combination of microarray and quantitative real-time PCR (QPCR analysis. The follicular status of F1 and F2 were further evaluated in terms of healthy and atretic conditions by investigating mRNA localization of identified genes. Methods Global gene expression profiles of F1 (10.7 +/- 0.7 mm and F2 (7.8 +/- 0.2 mm were analyzed by hierarchical cluster analysis and expression profiles of 16 representative genes were confirmed by QPCR analysis. In addition, localization of six identified transcripts was investigated in healthy and atretic follicles using in situ hybridization. The healthy or atretic condition of examined follicles was classified by progesterone and estradiol concentrations in follicular fluid. Results Hierarchical cluster analysis of microarray data classified the follicles into two clusters. Cluster A was composed of only F2 and was characterized by high expression of 31 genes including IGFBP5, whereas cluster B contained only F1 and predominantly expressed 45 genes including CYP19 and FSHR. QPCR analysis confirmed AMH, CYP19, FSHR, GPX3, PlGF, PLA2G1B, SCD and TRB2 were greater in F1 than F2, while CCL2, GADD45A, IGFBP5, PLAUR, SELP, SPP1, TIMP1 and TSP2 were greater in F2 than in F1. In situ hybridization showed that AMH and CYP19 were detected in granulosa cells (GC of healthy as well as atretic follicles. PlGF was localized in GC and in the theca layer (TL of healthy follicles. IGFBP5 was detected in both GC and TL of atretic follicles. GADD45A and TSP2 were localized in both GC and TL of atretic follicles, whereas healthy follicles expressed them only in GC. Conclusion We demonstrated that global gene expression profiling of F

    Full Text Available A modified multiple structural changes model is built to test structural breaks of the financial system based on calculating the largest Lyapunov exponents of the financial time series. Afterwards, the Lorenz system is used as a simulation example to inspect the new model. As the Lorenz system has strong nonlinearity, the verification results show that the new model has good capability in both finding the breakpoint and revealing the changes in nonlinear characteristics of the time series. The empirical study based on the model used daily data from the S&P 500 stock index during the global financial crisis from 2005 to 2012. The results provide four breakpoints of the period, which divide the contagion into four stages: stationary, local outbreak, global outbreak, and recovery period. An additional significant result is the obvious chaos characteristic difference in the largest Lyapunov exponents and the standard deviation at various stages, particularly at the local outbreak stage.

    2018-01-01

    Extreme value statistics and Bayesian methods are used to constrain the magnitudes of the largest expected earthquakes in a sequence governed by the parametric time-dependent occurrence rate and frequency-magnitude statistics. The Bayesian predictive distribution for the magnitude of the largest event in a sequence is derived. Two types of sequences are considered, that is, the classical aftershock sequences generated by large main shocks and the aftershocks generated by large foreshocks preceding a main shock. For the former sequences, the early aftershocks during a training time interval are used to constrain the magnitude of the future extreme event during the forecasting time interval. For the latter sequences, the earthquakes preceding the main shock are used to constrain the magnitudes of the subsequent extreme events including the main shock. The analysis is applied retrospectively to past prominent earthquake sequences.

    The statistics of extreme values is used to investigate the statistical properties of the largest areas sunspots and photospheric faculae per solar cycle. The largest values of the synodic-solar-rotation mean areas of umbrae, whole spots and faculae, which have been recorded for nine solar cycles, are each shown to comply with the general form of the extreme value probability function. Empirical expressions are derived for the three extreme value populations from which the characteristic statistical parameters, namely the mode, median, mean and standard deviation, can be calculated for each population. These three extreme value populations are also used to find the expected ranges of the extreme areas in a group of solar cycles as a function of the number of cycles in the group. The extreme areas of umbrae and whole spots have a dispersion comparable to that found by Siscoe for the extreme values of sunspot number, whereas the extreme areas of faculae have a smaller dispersion which is comparable to that found by Siscoe for the largest geomagnetic storm per solar cycle. The expected range of the largest sunspot area per solar cycle for a group of one hundred cycles appears to be inconsistent with the existence of the prolonged periods of sunspot minima that have been inferred from the historical information on solar variability. This inconsistency supports the contention that there are temporal changes of solar-cycle statistics during protracted periods of sunspot minima (or maxima). Indeed, without such temporal changes, photospheric faculae should have been continually observable throughout the lifetime of the Sun. (orig.)

    Prostate cancer is highly prevalent in Jamaica and is the leading cause of cancer-related deaths. Our aim was to evaluate the patterns of screening in the largest organized screening clinic in Jamaica at the Jamaica Cancer Society. A retrospective analysis of all men presenting for screening at the Jamaica Cancer Society from 1995 to 2005 was done. All patients had digital rectal examinations (DRE) and prostate specific antigen (PSA) tests done. Results of prostate biopsies were noted. 1117 men of mean age 59.9 ± 8.2 years presented for screening. The median documented PSA was 1.6 ng/mL (maximum of 5170 ng/mL). Most patients presented for only 1 screen. There was a gradual reduction in the mean age of presentation for screening over the period. Prostate biopsies were requested on 11% of screening visits; however, only 59% of these were done. 5.6% of all persons screened were found to have cancer. Of the cancers diagnosed, Gleason 6 adenocarcinoma was the commonest grade and median PSA was 8.9 ng/mL (range 1.5-1059 ng/mL). Older men tend to screen for prostate cancer in Jamaica. However, compliance with regular maintenance visits and requests for confirmatory biopsies are poor. Screening needs intervention in the Jamaican population.

    Large galaxy redshift surveys have long been used to constrain cosmological models and structure formation scenarios. In particular, the largest structures discovered observationally are thought to carry critical information on the amplitude of large-scale density fluctuations or homogeneity of the universe, and have often challenged the standard cosmological framework. The Sloan Great Wall (SGW) recently found in the Sloan Digital Sky Survey (SDSS) region casts doubt on the concordance cosmological model with a cosmological constant (i.e., the flat ΛCDM model). Here we show that the existence of the SGW is perfectly consistent with the ΛCDM model, a result that only our very large cosmological N-body simulation (the Horizon Run 2, HR2) could supply. In addition, we report on the discovery of a void complex in the SDSS much larger than the SGW, and show that such size of the largest void is also predicted in the ΛCDM paradigm. Our results demonstrate that an initially homogeneous isotropic universe with primordial Gaussian random phase density fluctuations growing in accordance with the general relativity can explain the richness and size of the observed large-scale structures in the SDSS. Using the HR2 simulation we predict that a future galaxy redshift survey about four times deeper or with 3 mag fainter limit than the SDSS should reveal a largest structure of bright galaxies about twice as big as the SGW.

  17. On the statistics of the largest geomagnetic storms per solar cycle

    1976-01-01

    The theory of extreme value statistics is applied to the first, second, and third largest geomagnetic storms in nine solar cycles measured by the average half-daily aa indices compiled by Mayaud. Analytic expressions giving the probability of the extremes per solar cycle as a contour function of storm magnitude are obtained by least squares fitting of the observations to the appropriate theoretical extreme value probability functions. The results are used to obtain the statistical characteristics (mode, median, mean, and standard deviation) for the extreme values. The results are applied to find the expected range of extreme values in a set as a function of the number of solar cycles in the set. We find that the expected range of the largest storm is quite narrow and is larger for the second and third largest storms. The observed range of the extreme half-daily aa index for the nine solar cycles is 354--546 γ. In a set of 100 cycles the range is expanded esentially to 311--680γ, an increase of only 39% in the range. The result supports the argument for a change in solar cycle statistics in the latter part of the Seventeenth Century (the Maunder minimum)

This article examines hospital prices in California over time with a focus on hospitals in the largest multi-hospital systems. Our data show that hospital prices in California grew substantially (+76% per hospital admission across all hospitals and all services between 2004 and 2013 and that prices at hospitals that are members of the largest, multi-hospital systems grew substantially more (113% than prices paid to all other California hospitals (70%. Prices were similar in both groups at the start of the period (approximately $9200 per admission. By the end of the period, prices at hospitals in the largest systems exceeded prices at other California hospitals by almost $4000 per patient admission. Our study findings are potentially useful to policy makers across the country for several reasons. Our data measure actual prices for a large sample of hospitals over a long period of time in California. California experienced its wave of consolidation much earlier than the rest of the country and as such our findings may provide some insights into what may happen across the United States from hospital consolidation including growth of large, multi-hospital systems now forming in the rest of the rest of the country.

  19. Collaborative spectrum sensing based on the ratio between largest eigenvalue and Geometric mean of eigenvalues

    KAUST Repository

    Shakir, Muhammad

    2011-12-01

    In this paper, we introduce a new detector referred to as Geometric mean detector (GEMD) which is based on the ratio of the largest eigenvalue to the Geometric mean of the eigenvalues for collaborative spectrum sensing. The decision threshold has been derived by employing Gaussian approximation approach. In this approach, the two random variables, i.e. The largest eigenvalue and the Geometric mean of the eigenvalues are considered as independent Gaussian random variables such that their cumulative distribution functions (CDFs) are approximated by a univariate Gaussian distribution function for any number of cooperating secondary users and received samples. The approximation approach is based on the calculation of exact analytical moments of the largest eigenvalue and the Geometric mean of the eigenvalues of the received covariance matrix. The decision threshold has been calculated by exploiting the CDF of the ratio of two Gaussian distributed random variables. In this context, we exchange the analytical moments of the two random variables with the moments of the Gaussian distribution function. The performance of the detector is compared with the performance of the energy detector and eigenvalue ratio detector. Analytical and simulation results show that our newly proposed detector yields considerable performance advantage in realistic spectrum sensing scenarios. Moreover, our results based on proposed approximation approach are in perfect agreement with the empirical results. © 2011 IEEE.

    This paper explores India's role in the world illicit opiate market, particularly its role as a producer. India, a major illicit opiate consumer, is also the sole licensed exporter of raw opium: this unique status may be enabling substantial diversion to the illicit market. Participant observation and interviews were carried out at eight different sites. Information was also drawn from all standard secondary sources and the analysis of about 180 drug-related criminal proceedings reviewed by Indian High Courts and the Supreme Court from 1985 to 2001. Diversion from licit opium production takes place on such a large scale that India may be the third largest illicit opium producer after Afghanistan and Burma. With the possible exceptions of 2005 and 2006, 200-300 tons of India's opium may be diverted yearly. After estimating India's opiate consumption on the basis of UN-reported prevalence estimates, we find that diversion from licit production might have satisfied a quarter to more than a third of India's illicit opiate demand to 2004. India is not only among the world's largest consumer of illicit opiates but also one of the largest illicit opium producers. In contrast to all other illicit producers, India owes the latter distinction not to blatantly illicit cultivation but to diversion from licit cultivation. India's experience suggests the difficulty of preventing substantial leakage, even in a relatively well-governed nation.

    An emerging dimension of 21(st) century integrative biology is knowledge translation in global health. The maternal mortality rate in Somalia is amongst the highest in the world. We set out to study the "know-do" gap in family planning measures in Somalia, with a view to inform future interventions for knowledge integration between theory and practice. We interviewed 360 Somali females of reproductive age and compared university-educated females to women with less or no education, using structured interviews, with a validated questionnaire. The mean age of marriage was 18 years, with 4.5 pregnancies per marriage. The mean for the desired family size was 9.3 and 10.5 children for the university-educated group and the less-educated group, respectively. Importantly, nearly 90% of the university-educated group knew about family planning, compared to 45.6% of the less-educated group. All of the less-educated group indicated that they would never use contraceptives, as compared to 43.5% of the university-educated group. Prevalence of contraceptive use among ever-married women was 4.3%. In the less-educated group, 80.6% indicated that they would not recommend contraceptives to other women as compared to 66.0% of the university-educated group. There is a huge gap between knowledge and practice regarding family planning in Somalia. The attendant reasons for this gap, such as level of education, expressed personal religious beliefs and others, are examined here. For primary health care to gain traction in Africa, we need to address the existing "know-do" gaps that are endemic and adversely impacting on global health. This is the first independent research study examining the knowledge gaps for family planning in Somalia in the last 20 years, with a view to understanding knowledge integration in a global world. The results shall guide policy makers, donors, and implementers to develop a sound family planning policy and program to improve maternal and child health in 21(st

    Asylum seekers, refugees and persons without legal status have been reported to experience a range of difficulties when accessing public services and supports in the UK. While research has identified health care barriers to equitable access such as language difficulties, it has not considered the broader social contexts of marginalization experienced through the dynamics of 'othering'. The current study explores health and health care experiences of Somali and Iraqi asylum seekers, refugees and persons without legal status, highlighting 'minoritization' processes and the 'pathologization' of difference as analytical lenses to understand the multiple layers of oppression that contribute to health inequities. For the study, qualitative methods were used to document the lived experiences of asylum seekers, refugees and persons without legal status. Thirty-five in-depth interviews and five focus groups were used to explore personal accounts, reveal shared understandings and enable social, cognitive and emotional understandings of on-going health problems and challenges when seeking treatment and care. A participatory framework was undertaken which inspired collaborative workings with local organizations that worked directly with asylum seekers, refugees and persons without legal status. The analysis revealed four key themes: 1) pre-departure histories and post-arrival challenges; 2) legal status; 3) health knowledges and procedural barriers as well as 4) language and cultural competence. Confidentiality, trust, wait times and short doctor-patient consultations were emphasized as being insufficient for culturally specific communications and often translating into inadequate treatment and care. Barriers to accessing health care was associated with social disadvantage and restrictions of the broader welfare system suggesting that a re-evaluation of the asylum seeking process is required to improve the situation. Macro- and micro-level intersections of accustomed societal

    Human Immunodeficiency Virus (HIV) continues to take a heavy toll on the lives of many people, with the worst impact on health and wellbeing for the affected individuals in fragile states. The HIV situation in Somalia is not clearly known and experiences of the people living with HIV in this war-torn region are often unexpressed. This pilot qualitative study sought to explore the experiences of people diagnosed with HIV living in Mogadishu, and their resilience in access to care and social support. Participants were recruited through drug dispensers at the HIV clinic in Banadir Hospital. Face-to-face in-depth interviews were conducted in Somali in May 2013 among patients who were receiving antiretroviral therapy (ART) from the HIV clinic in Mogadishu. These were tape-recorded, transcribed, and translated for content analysis. Three women and four men who were living with HIV shared the following narratives. Their perception was that they had either got HIV from their spouses or through health care contamination. They were very knowledgeable about the realities of HIV, how the medication works, nutritional requirements, and drug adherence. They were always willing to go an extra mile to secure a good life for themselves. However, the external HIV stigma impacted their access to care. They faced challenges in their homes and at work which compelled them to seek support from non-governmental organizations (NGOs) or close family members. This stigma often affected their disclosure to the wider community due to the uncertainty of the repercussions, leading to a life of extreme loneliness and financial difficulties. The participants' coping mechanisms included living together and starting their own NGO for support with very strong optimism about their prognosis. The people diagnosed with HIV living in Mogadishu are highly knowledgeable about HIV transmission, the realities of living with a diagnosed HIV infection, and the efficacy of HIV treatment.

    Full Text Available This paper presents an ideal method for object tracking directly in the compressed domain in video sequences. An enhanced rotation-invariant image operator called Largest Difference Indexed Local Ternary Pattern (LDILTP has been proposed. The Local Ternary Pattern which worked very well in texture classification and face recognition is now extended for rotation invariant object tracking. Histogramming the LTP code makes the descriptor resistant to translation. The histogram intersection is used to find the similarity measure. This method is robust to noise and retain contrast details. The proposed scheme has been verified on various datasets and shows a commendable performance.

    Full Text Available The aim of this paper is to test the impacts of oil price increases on monetary policy implementation in the largest oil importers. For that purpose, we estimate structural vector error correction (SVEC models to show the impacts of oil price increases on industrial production, consumer prices and immediate interest rates which are the elements of Taylor rule for the four largest oil importers (the USA, the EU, China and Japan. Our results indicate that oil price increases transmit to output and inflation and lead to fluctuations in industrial production, consumer prices and immediate interest rates which in turn influence the monetary policy stance in the following periods. The basic conclusion of research is that the channels through which oil prices affect output, inflation and interest rates should be identified by the monetary policy authorities of the USA, the EU, China and Japan. We also emphasize the importance of the determination of the optimal monetary policy framework to eliminate the negative consequences of oil price increases.

    In 1998, ESM (Electric Power Co. of Macedonia) received a loan from the International Bank for Reconstruction and Development (IBRD - The World bank) for the cost of the Power System Improvement Project, major part of which is the partial rehabilitation of the six largest HPPs in the Republic of Macedonia. Rehabilitation and life extension of these six largest hydro power plants is given the highest priority in the whole Power System Improvement Project mainly because these HPPs are, in general, fairly old, older than most of the thermal generation capacity and because a significant part of their equipment is wearing out, or is now obsolete with spare parts difficult to obtain. Furthermore, these plants play a vital role in the Macedonian Power System, providing peaking capacity, reserve capacity and frequency control. With the realization of this project, greater hydropower production is expected. It is also expected that HPPs will become a more vital part of the Macedonian Power System, which is also beneficial from an environmental aspect, due to greater usage of renewable energy resources in the country.

    Full Text Available The disclosure of sustainable practices has become important in the search for competitive advantage, so as to meet the expectations of the various stakeholders. Thus, the study aims to investigate the relationship between the ownership structure and the economic and environmental voluntary disclosure in the largest Brazilian companies, analyzing ownership concentration and the identity of the controlling shareholder. For the analysis, we considered the economic, social and environmental perspectives, addressed both individually and jointly. The sample consists of 47 companies from the 100 largest public companies listed on BM&FBOVESPA, according to the magazine Exame Biggest and Best, edition 2013. The research is descriptive and quantitative, using Multiple Linear Regression for statistical analysis. The descriptive analysis of the prospects of (economic, social, environmental and sustainability disclosure showed lower average disclosure for the environmental aspect. The state control organizations stood out with the highest average in three of the four levels of disclosure: economic, social and sustainability. As regards the application of statistical analysis, the regression models were not statistically significant, indicating that, for the companies in the sample, the ownership structure does not influence the economic and socio-environmental disclosure.

  16. An exploration of the connection between two meaning perspectives: an evidence-based approach to health information delivery to vulnerable groups of Arabic- and Somali-speaking asylum seekers in a Swedish context.

    The right to health care is significant for asylum seekers, particularly as many of them have experienced traumatic life events in their home country, during flight or in their host country. Post-migration living conditions have more impact than pre-migration conditions on ill health among asylum seekers, which underscores the importance of health care-related refugee reception policies. The purpose of this article is to explore the perceived meaning of comprehensive health information provided by a nurse to Arabic- and Somali-speaking adult asylum seekers, in a Swedish context, during its introduction at the Migration Board. In our study, the endpoint was whether asylum seekers found such health information relevant, understandable and respectful. Following an oral presentation, participants filled in a questionnaire consisting of three close-ended questions. A total of 39 groups of presentation attendees included 626 asylum seekers (415 Arabic- and 211 Somali-speaking). Data were analysed with descriptive statistics. Comments underwent content analysis. We also present some socio-demographic data on these asylum seekers. Independently of gender and language, the participants expressed their gratitude for and the meaningfulness of receiving professional, fact-based information, as well as being treated with concern and respect. They indicated a great need for this and felt relieved by being listened to. They liked the pedagogic group method, the opportunity for dialogue and to practice exercising their rights. These promising results indicate that exercising the asylum-seekers' right to receive such health information would improve future reception policies not only in Sweden, but throughout the EU. A renewed focus on communication and pedagogic skills, instead of just cultural training, should be considered for health care professionals assisting asylum seekers.

    Directory of Open Access Journals (Sweden)

    Kuenzer, Claudia

    2013-09-01

    Full Text Available The Tonle Sap ecosystem in Cambodia is Southeast Asia’s largest freshwater lake; strongly impacted by the Mekong river flood pulse. The lake is home to exceptional biodiversity, and rural communities living in free floating villages on the lake and on its shores. The fragile niche ecosystems as well as the rural livelihoods of Tonle Sap are under severe threat. Overfishing, illegal wood harvesting, further resource exploitation, and water quality deterioration all impact the stability of the socio-ecological system of Tonle Sap. At the same time, expected flood pulse changes due to regulatory measures in the context of hydropower development upstream on the Mekong are a severe threat for Tonle Sap’s ecosystem stability. The area needs to shift into the focus of attention of national and international re-searchers, stakeholders, and decision makers, to find suitable pathways for a future sustainable development of this unique and pristine region.

    In September 1995, a project was initiated to replace the existing drive line at NASA's most unique transonic wind tunnel, the National Transonic Facility (NTF), with a single 101 MW synchronous motor driven by a Load Commutated Inverter (LCI). This Adjustable Speed Drive (ASD) system also included a custom four-winding transformer, harmonic filter, exciter, switch gear, control system, and feeder cable. The complete system requirements and design details have previously been presented and published [1], as well as the commissioning and acceptance test results [2]. The NTF was returned to service in December 1997 with the new drive system powering the fan. Today, this installation still represents the world s largest horizontal single motor/drive combination. This paper describes some significant events that occurred with the drive system during the first 15 years of service. These noteworthy issues are analyzed and root causes presented. Improvements that have substantially increased the long term viability of the system are given.

    Mauna Loa on the Island Hawaiʻi is the world’s largest volcano. People residing on its flanks face many hazards that come with living on or near an active volcano, including lava flows, explosive eruptions, volcanic smog, damaging earthquakes, and local tsunami (giant seawaves). The County of Hawaiʻi (Island of Hawaiʻi) is the fastest growing County in the State of Hawaii. Its expanding population and increasing development mean that risk from volcano hazards will continue to grow. U.S. Geological Survey (USGS) scientists at the Hawaiian Volcano Observatory (HVO) closely monitor and study Mauna Loa Volcano to enable timely warning of hazardous activity and help protect lives and property.

    Full Text Available This article explores the need for libraries to algorithmically access and manipulate the world’s largest API: the Internet. The billions of pages on the ‘Internet API’ (HTTP, HTML, CSS, XPath, DOM, etc. are easily accessible and manipulable. Libraries can assist in creating meaning through the datafication of information on the world wide web. Because most information is created for human consumption, some programming is required for automated extraction. Python is an easy-to-learn programming language with extensive packages and community support for web page automation. Four packages (Urllib, Selenium, BeautifulSoup, Scrapy in Python can automate almost any web page for all sized projects. An example warrant data project is explained to illustrate how well Python packages can manipulate web pages to create meaning through assembling custom datasets.

    Randomized algorithms and data structures are often analyzed under the assumption of access to a perfect source of randomness. The most fundamental metric used to measure how “random” a hash function or a random number generator is, is its independence: a sequence of random variables is said...... to be k-independent if every variable is uniform and every size k subset is independent. In this paper we consider three classic algorithms under limited independence. Besides the theoretical interest in removing the unrealistic assumption of full independence, the work is motivated by lower independence...... being more practical. We provide new bounds for randomized quicksort, min-wise hashing and largest bucket size under limited independence. Our results can be summarized as follows. Randomized Quicksort.

    2017-01-01

    Full Text Available The very well known example of cosmology testing particle physics is the number of relativistic particles (photons and three active neutrinos within the Standard Model at primordial nucleosynthesis. These days the earliest moment we can hope to probe with present cosmological data is the early time inflation. The particle physics conditions there and now are different because of different energy scales and different values of the scalar fields, that usually prohibits a reliable connection between the particle physics parameters at the two interesting epochs. The physics at the highest energy scales may be probed with observations at the largest spatial scales (just somewhat smaller than the size of the visible Universe. However, we are not (yet ready to make the tests realistic, because of lack of a self-consistent theoretical description of the presently favorite cosmological models to be valid right after inflation.

    Full Text Available The Klein Karoo National Arts Festival (KKNK in Oudtshoorn, South Africa, is the largest arts festival in South Africa. The purpose of this research was to determine the attributes and role of the entrepreneurs at the Klein Karoo National Arts Festival. This was done by means of a questionnaire survey (N=249. After data capturing was completed, two factor analyses were conducted. The first factor analysis revealed six factors (entrepreneurial attributes, namely organisational skills, resourcefulness, self-edification, explorative, acquired skill and drive, of which resourcefulness had the highest mean value. The second factor analysis identified the role of entrepreneurs at KKNK and revealed three primary roles, namely festival promotion, product promotion and income generation, of which product promotion had the highest mean value. This is the first time that the roles of entrepreneurs at festivals were investigated in South Africa.

    Full Text Available The changes taking place in the labor market cause that it is increasingly difficult to recruit employees with the right skills and competencies to companies. To reach the right candidates, they use modern IT solutions, such as ATS (Applicant Tracking System, which are supporting the processes of recruitment. Among others, they enable the publication of job offers on the Internet - on corporate websites, job portals and business social networking services - and apply for jobs online through these channels. This article pre-sents the evolution of the use of the Internet, and particularly the social media, in the recruitment process and presents a projekt of comprehensive research, which aims is to analyze and evaluate of the level of development of e-recruitment in Poland among largest companies.

    The economic assessment of the impacts of storm surges and sea-level rise in coastal cities requires high-level information on the damage and protection costs associated with varying flood heights. We provide a systematically and consistently calculated dataset of macroscale damage and protection cost curves for the 600 largest European coastal cities opening the perspective for a wide range of applications. Offering the first comprehensive dataset to include the costs of dike protection, we provide the underpinning information to run comparative assessments of costs and benefits of coastal adaptation. Aggregate cost curves for coastal flooding at the city-level are commonly regarded as by-products of impact assessments and are generally not published as a standalone dataset. Hence, our work also aims at initiating a more critical discussion on the availability and derivation of cost curves. PMID:29557944

    2016-01-01

    The aim of this paper is the study of instability state of boiling water reactors with a method based in largest Lyapunov exponents (LLEs). Detecting the presence of chaos in a dynamical system is an important problem that is solved by measuring the LLE. Lyapunov exponents quantify the exponential divergence of initially close state-space trajectories and estimate the amount of chaos in a system. This method was applied to a set of signals from several nuclear power plant (NPP) reactors under commercial operating conditions that experienced instabilities events, apparently each of a different nature. Laguna Verde and Forsmark NPPs with in-phase instabilities, and Cofrentes NPP with out-of-phases instability. This study presents the results of intrinsic instability in the boiling water reactors of three NPPs. In the analyzed cases the limit cycle was not reached, which implies that the point of equilibrium exerts influence and attraction on system evolution

    Suncor Energy is the first company in Canada to use a new technology designed uniquely for tire recycling at oil sand facilities. The technology is owned by CuttingEdge Tire Recycling, a partnership between Denesoline Environmental Limited Partnership and Beaver Environmental Rubber Technologies Limited. Suncor has supported the development of this Aboriginal-owned and operated business by offering land, electricity, diesel fuel and stockpiles of used truck tires from its oil sand mining activities. These tires are the largest off-road tires in the world. In this new technology, tires that are worn-out through oil sand mining are shredded in a portable shredder before being recycled for subsequent use by the Alberta Recycling Management Association. 1 fig.

    For the radiation exposure caused by human activities, the enhanced natural radiation exposure is the largest contributor to Chinese population dose. This problem has attracted social attention in recent years. Efforts have been made in several fields, such as radon indoors and in workplace, environmental problems associated with NORMs, occupational radiation hazards of non-uranium mine, and radiation dose evaluation for energy chain, but there are still many problems to be solved. In order to protect the health of workers and the public, while ensuring industrial production and economic development, it is also necessary to continue to strengthen research in all aspects above mentioned, and gradually promote the control of natural radiation exposure enhanced by human activities.

  12. A marine heatwave drives massive losses from the world’s largest seagrass carbon stocks

    Arias-Ortiz, A.

    2018-03-29

    Seagrass ecosystems contain globally significant organic carbon (C) stocks. However, climate change and increasing frequency of extreme events threaten their preservation. Shark Bay, Western Australia, has the largest C stock reported for a seagrass ecosystem, containing up to 1.3% of the total C stored within the top metre of seagrass sediments worldwide. On the basis of field studies and satellite imagery, we estimate that 36% of Shark Bay’s seagrass meadows were damaged following a marine heatwave in 2010/2011. Assuming that 10 to 50% of the seagrass sediment C stock was exposed to oxic conditions after disturbance, between 2 and 9 Tg CO could have been released to the atmosphere during the following three years, increasing emissions from land-use change in Australia by 4–21% per annum. With heatwaves predicted to increase with further climate warming, conservation of seagrass ecosystems is essential to avoid adverse feedbacks on the climate system.

    The 2012 submarine eruption of Havre volcano in the Kermadec arc, New Zealand, is the largest deep-ocean eruption in history and one of very few recorded submarine eruptions involving rhyolite magma. It was recognized from a gigantic 400-km 2 pumice raft seen in satellite imagery, but the complexity of this event was concealed beneath the sea surface. Mapping, observations, and sampling by submersibles have provided an exceptionally high fidelity record of the seafloor products, which included lava sourced from 14 vents at water depths of 900 to 1220 m, and fragmental deposits including giant pumice clasts up to 9 m in diameter. Most (>75%) of the total erupted volume was partitioned into the pumice raft and transported far from the volcano. The geological record on submarine volcanic edifices in volcanic arcs does not faithfully archive eruption size or magma production.

    Speed is the fundamental constraint on animal movement, yet there is no general consensus on the determinants of maximum speed itself. Here, we provide a general scaling model of maximum speed with body mass, which holds across locomotion modes, ecosystem types and taxonomic groups. In contrast to traditional power-law scaling, we predict a hump-shaped relationship resulting from a finite acceleration time for animals, which explains why the largest animals are not the fastest. This model is strongly supported by extensive empirical data (474 species, with body masses ranging from 30 μg to 100 tonnes) from terrestrial as well as aquatic ecosystems. Our approach unravels a fundamental constraint on the upper limit of animal movement, thus enabling a better understanding of realized movement patterns in nature and their multifold ecological consequences.

    2008-07-01

    This article describes the solar thermal installation on the Hotel Europa in St. Moritz-Champfer, Switzerland. The installation provides heat energy for domestic hot water preparation and for the heating of the hotel's indoor swimming pool. A thirty-percent reduction of heating oil consumption has been obtained. The system, which is based on the 'low-flow' principle, provides the highest possible temperature difference while using low pumping energy. The hotel's hot-water circulation system, which ensures fast availability of hot water at the taps, is also discussed. This largest hotel solar installation is designed to meet heating and hot-water requirements during the summer season. The high requirements placed on the materials used are discussed. Schematics are provided and first operational experience is briefly discussed.

    With the support of the International Climate Initiative (ICI) of the Federal Ministry of the Environment, Conservation, and Nuclear Security, the implementation of the German Development Bank KfW, the World Wide Fund for Nature (WWF) Germany, the University of California Los Angeles (UCLA) and local DRC partners will produce a national scale biomass map for the entire forest coverage of the Democratic Republic of Congo (DRC) along with feasibility assessments of different forest protection measures within a framework of a REDD+ model project. The « Carbon Map and Model (CO2M&M) » project will produce a national forest biomass map for the DRC, which will enable quantitative assessments of carbon stocks and emissions in the largest forest of the Congo Basin. This effort will support the national REDD (Reducing Emissions from Deforestation and Degradation) program in DRC, which plays a major role in sustainable development and poverty alleviation. This map will be developed from field data, complemented by airborne LiDAR (Light Detection and Ranging) and aerial photos, systematically sampled throughout the forests of the DRC and up-scaled to satellite images to accurately estimate carbon content in all forested areas. The second component of the project is to develop specific approaches for model REDD projects in key landscapes. This project represents the largest LiDAR-derived mapping effort in Africa, under unprecedented logistical constraints, which will provide one of the poorest nations in the world with the richest airborne and satellites derived datasets for analyzing forest structure, biomass and biodiversity.

  1. Dissolved Oxygen Dynamics in Backwaters of North America's Largest River Swamp

    The Atchafalaya River (AR) is the largest distributary of the Mississippi River flowing through south-central Louisiana, creating North America's largest river swamp basin - the Atchafalaya River Basin (ARB). Prior to human settlement, the AR's main channel was highly connected to this large wetland ecosystem. However, due to constructed levee systems and other human modifications, much of the ARB is now hydrologically disconnected from the AR's main channel except during high flow events. This lack of regular inputs of fresh, oxygenated water to these wetlands, paired with high levels of organic matter decomposition in wetlands, has caused low oxygen-deprived hypoxic conditions in the ARB's back waters. In addition, due to the incredibly nutrient-rich and warm nature of the ARB, microbial decomposition in backwater areas with limited flow often results in potentially stressful, if not lethal, levels of DO for organisms during and after flood pulses. This study aims to investigate dynamics of dissolved oxygen in backwaters of the Atchafalaya River Basin, intending to answer a crucial question about hydrological and water quality connectivity between the river's mainstem and its floodplain. Specifically, the study will 1) conduct field water quality measurements, 2) collect composite water samples for chemical analysis of nutrients and carbon, 3) investigate DO dynamics over different seasons for one year, and 4) determine the major factors that affect DO dynamics in this unique swamp ecosystem. The study is currently underway; therefore, in this presentation we will share the major findings gained in the past several months and discuss backwater effects on river chemistry.

  2. Is Kasei Valles (Mars) the largest volcanic channel in the solar system?

    2018-02-01

    With a length of more than 2000 km and widths of up to several hundred kilometers, Kasei Valles is the largest outflow system on Mars. Superficially, the scabland-like character of Kasei Valles is evocative of terrestrial systems carved by catastrophic aqueous floods, and the system is widely interpreted as a product of outbursts from aquifers. However, as at other Martian outflow channels, clear examples of fluvial sedimentary deposits have proven difficult to identify here. Though Kasei Valles lacks several key properties expected of aqueous systems, its basic morphological and contextual properties are aligned with those of ancient volcanic channels on Venus, the Moon, Mercury, and Earth. There is abundant evidence that voluminous effusions of low-viscosity magmas occurred at the head of Kasei Valles, the channel system acted as a conduit for associated flows, and mare-style volcanic plains developed within its terminal basin. Combined mechanical and thermal incision rates of at least several meters per day are estimated to have been readily achieved at Kasei Valles by 20-m-deep magmas flowing with viscosities of 1 Pa s across low topographic slopes underlain by bedrock. If Kasei Valles formed through incision by magma, it would be the largest known volcanic channel in the solar system. The total volume of magma erupted at Kasei Valles is estimated here to have possibly reached or exceeded ∼5 × 106 km3, a volume comparable in magnitude to those that characterize individual Large Igneous Provinces on Earth. Development of other large outflow systems on Mars is expected to have similarly involved eruption of up to millions of cubic kilometers of magma.

  3. Landscapes of thermal inequity: disproportionate exposure to urban heat in the three largest US cities

    Heat waves are the most significant cause of mortality in the US compared to other natural hazards. Prior studies have found increased heat exposure for individuals of lower socioeconomic status in several US cities, but few comparative analyses of the social distribution of urban heat have been conducted. To address this gap, our paper examines and compares the environmental justice consequences of urban heat risk in the three largest US cities: New York City, Los Angeles, and Chicago. Risk to urban heat is estimated on the basis of three characteristics of the urban thermal landscape: land surface temperature, vegetation abundance, and structural density of the built urban environment. These variables are combined to develop an urban heat risk index, which is then statistically compared with social vulnerability indicators representing socioeconomic status, age, disability, race/ethnicity, and linguistic isolation. The results indicate a consistent and significant statistical association between lower socioeconomic and minority status and greater urban heat risk, in all three cities. Our findings support a growing body of environmental justice literature that indicates the presence of a landscape of thermal inequity in US cities and underscores the need to conduct comparative analyses of social inequities in exposure to urban heat.

    We report the discovery of a new Kepler transiting circumbinary planet (CBP). This latest addition to the still-small family of CBPs defies the current trend of known short-period planets orbiting near the stability limit of binary stars. Unlike the previous discoveries, the planet revolving around the eclipsing binary system Kepler-1647 has a very long orbital period (∼1100 days) and was at conjunction only twice during the Kepler mission lifetime. Due to the singular configuration of the system, Kepler-1647b is not only the longest-period transiting CBP at the time of writing, but also one of the longest-period transiting planets. With a radius of 1.06 ± 0.01 R {sub Jup}, it is also the largest CBP to date. The planet produced three transits in the light curve of Kepler-1647 (one of them during an eclipse, creating a syzygy) and measurably perturbed the times of the stellar eclipses, allowing us to measure its mass, 1.52 ± 0.65 M {sub Jup}. The planet revolves around an 11-day period eclipsing binary consisting of two solar-mass stars on a slightly inclined, mildly eccentric ( e {sub bin} = 0.16), spin-synchronized orbit. Despite having an orbital period three times longer than Earth’s, Kepler-1647b is in the conservative habitable zone of the binary star throughout its orbit.

    Marine reserves can restore fish abundance and diversity in areas impacted by overfishing, but the effectiveness of reserves in developing countries where resources for enforcement are limited, have seldom been evaluated. Here we assess whether the establishment in 1996 of the largest marine reserve in the Caribbean, Gardens of the Queen in Cuba, has had a positive effect on the abundance of commercially valuable reef fish species in relation to neighboring unprotected areas. We surveyed 25 sites, including two reef habitats (reef crest and reef slope), inside and outside the marine reserve, on five different months, and over a one-and-a-half year period. Densities of the ten most frequent, highly targeted, and relatively large fish species showed a significant variability across the archipelago for both reef habitats that depended on the month of survey. These ten species showed a tendency towards higher abundance inside the reserve in both reef habitats for most months during the study. Average fish densities pooled by protection level, however, showed that five out of these ten species were at least two-fold significantly higher inside than outside the reserve at one or both reef habitats. Supporting evidence from previously published studies in the area indicates that habitat complexity and major benthic communities were similar inside and outside the reserve, while fishing pressure appeared to be homogeneous across the archipelago before reserve establishment. Although poaching may occur within the reserve, especially at the boundaries, effective protection from fishing was the most plausible explanation for the patterns observed.

    To address how various environmental parameters control or constrain planktonic respiration (PR), we used geometric scaling relationships and established biological scaling laws to derive quantitative predictions for the relationships among key drivers of PR. We then used empirical measurements of PR and environmental (soluble reactive phosphate [SRP], carbon [DOC], chlorophyll a [Chl-a)], and temperature) and landscape parameters (lake area [LA] and watershed area [WA]) from a set of 44 lakes that varied in size and trophic status to test our hypotheses. We found that landscape-level processes affected PR through direct effects on DOC and temperature and indirectly via SRP. In accordance with predictions made from known relationships and scaling laws, scale coefficients (the parameter that describes the shape of a relationship between 2 variables) were found to be negative and have an absolute value 1, others respiration from small pond catchments to the largest body of freshwater on the planet, Lake Superior, these findings should be applicable to controls of PR for the great majority of temperate aquatic ecosystems.

    Efforts to improve science education include university science departments hiring Science Faculty with Education Specialties (SFES), scientists who take on specialized roles in science education within their discipline. Although these positions have existed for decades and may be growing more common, few reports have investigated the SFES approach to improving science education. We present comprehensive data on the SFES in the California State University (CSU) system, the largest university system in the United States. We found that CSU SFES were engaged in three key arenas including K-12 science education, undergraduate science education, and discipline-based science education research. As such, CSU SFES appeared to be well-positioned to have an impact on science education from within science departments. However, there appeared to be a lack of clarity and agreement about the purpose of these SFES positions. In addition, formal training in science education among CSU SFES was limited. Although over 75% of CSU SFES were fulfilled by their teaching, scholarship, and service, our results revealed that almost 40% of CSU SFES were seriously considering leaving their positions. Our data suggest that science departments would likely benefit from explicit discussions about the role of SFES and strategies for supporting their professional activities.

    Microplastic pollution was studied in China's largest inland lake - Qinghai Lake in this work. Microplastics were detected with abundance varies from 0.05 × 10 5 to 7.58 × 10 5 items km -2 in the lake surface water, 0.03 × 10 5 to 0.31 × 10 5 items km -2 in the inflowing rivers, 50 to 1292 items m -2 in the lakeshore sediment, and 2 to 15 items per individual in the fish samples, respectively. Small microplastics (0.1-0.5 mm) dominated in the lake surface water while large microplastics (1-5 mm) are more abundant in the river samples. Microplastics were predominantly in sheet and fiber shapes in the lake and river water samples but were more diverse in the lakeshore sediment samples. Polymer types of microplastics were mainly polyethylene (PE) and polypropylene (PP) as identified using Raman Spectroscopy. Spatially, microplastic abundance was the highest in the central part of the lake, likely due to the transport of lake current. Based on the higher abundance of microplastics near the tourist access points, plastic wastes from tourism are considered as an important source of microplastics in Qinghai Lake. As an important area for wildlife conservation, better waste management practice should be implemented, and waste disposal and recycling infrastructures should be improved for the protection of Qinghai Lake.

    Full Text Available Making new breakthroughs in understanding the processes underlying human cognition may depend on the availability of very large datasets that have not historically existed in psychology and neuroscience. Lumosity is a web-based cognitive training platform that has grown to include over 600 million cognitive training task results from over 35 million individuals, comprising the largest existing dataset of human cognitive performance. As part of the Human Cognition Project, Lumosity’s collaborative research program to understand the human mind, Lumos Labs researchers and external research collaborators have begun to explore this dataset in order uncover novel insights about the correlates of cognitive performance. This paper presents two preliminary demonstrations of some of the kinds of questions that can be examined with the dataset. The first example focuses on replicating known findings relating lifestyle factors to baseline cognitive performance in a demographically diverse, healthy population at a much larger scale than has previously been available. The second example examines a question that would likely be very difficult to study in laboratory-based and existing online experimental research approaches: specifically, how learning ability for different types of cognitive tasks changes with age. We hope that these examples will provoke the imagination of researchers who are interested in collaborating to answer fundamental questions about human cognitive performance.

    The Gond comprise the largest tribal group of India with a population exceeding 12 million. Linguistically, the Gond belong to the Gondi-Manda subgroup of the South Central branch of the Dravidian language family. Ethnographers, anthropologists and linguists entertain mutually incompatible hypotheses on their origin. Genetic studies of these people have thus far suffered from the low resolution of the genetic data or the limited number of samples. Therefore, to gain a more comprehensive view on ancient ancestry and genetic affinities of the Gond with the neighbouring populations speaking Indo-European, Dravidian and Austroasiatic languages, we have studied four geographically distinct groups of Gond using high-resolution data. All the Gond groups share a common ancestry with a certain degree of isolation and differentiation. Our allele frequency and haplotype-based analyses reveal that the Gond share substantial genetic ancestry with the Indian Austroasiatic (ie, Munda) groups, rather than with the other Dravidian groups to whom they are most closely related linguistically.

    A new regulatory guide has been issued by the Nuclear Regulation Authority of Japan since the last year. According to this guide, electric power companies have to assess the influence of tornadoes on their nuclear power plants for operation. The purpose of this study is to evaluate the likelihood of the occurrence of F3 tornadoes, which are the largest encountered in Japan, and to consider the possibility of the regionalization of the maximum wind speed. Then, mesoscale analysis with a numerical meteorological model and re-analysis data is performed along with synoptic scale analysis. Especially, tornado parameters such as SReH (Storm Relative Helicity) and CAPE (Convective Available Potential Energy) are used for evaluating the potential tornadogenesis of F3 tornado. Both analyses indicate that favorable meteorological condition tends to occur in the coastal zones in the Pacific side west of Ibaraki and around Kyushu island. The frequency in these zones is different from the one in the other area in the order of 1 or 2, which is large enough for regionalization. (author)

    Lipoprotein apheresis (LA) has proven to be an effective, safe and life-saving therapy. Vascular access is needed to facilitate this treatment but has recognised complications. Despite consistency in treatment indication and duration there are no guidelines in place. The aim of this study is to characterise vascular access practice at the UK's largest LA centre and forward suggestions for future approaches. A retrospective analysis of vascular access strategies was undertaken in all patients who received LA treatment in the low-density lipoprotein (LDL) Apheresis Unit at Harefield Hospital (Middlesex, UK) from November 2000 to March 2016. Fifty-three former and current patients underwent 4260 LA treatments. Peripheral vein cannulation represented 79% of initial vascular access strategies with arteriovenous (AV) fistula use accounting for 15%. Last used method of vascular access was peripheral vein cannulation in 57% versus AV fistula in 32%. Total AV fistula failure rate was 37%. Peripheral vein cannulation remains the most common method to facilitate LA. Practice trends indicate a move towards AV fistula creation; the favoured approach receiving support from the expert body in this area. AV fistula failure rate is high and of great concern, therefore we suggest the implementation of upper limb ultrasound vascular mapping in all patients who meet treatment eligibility criteria. We encourage close ties between apheresis units and specialist surgical centres to facilitate patient counselling and monitoring. Further prospective data regarding fistula failure is needed in this expanding treatment field.

    Isla de Mona, a small, uplifted carbonate plateau jutting out of the waters of the Mona Passage, is an incredibly fragile and densely karstic environment. Expedition work was conducted by the Isla de Mona Project in cooperation with the Departamento Recursos Naturales y Ambientales de Puerto Rico (DRNA), including contributions from many researchers and cavers volunteering from across the U.S and Puerto Rico in the course of 12 separate expeditions, spanning a 14 year period (1998 to 2013). Over 200 caves have been documented on the island to date, the majority of this inventory is composed of flank margin caves but also includes sea caves, pit caves and talus caves. The most extensive example of cave development on the island is Sistema Faro - a sprawling maze-like series of chambers formed within the eastern point of the island with over 40 cliffside entrances overlooking the Caribbean Sea. Detailed cartography and analysis of the geomorphology and development of the Sistema Faro has helped form a complex model of carbonate island cave development as a function of tectonic uplift, lithology, sea level changes, karst hydrogeology and cliff retreat. This communication examines the roles these controls have played in the genesis of the world's largest flank margin cave. (Author)

  14. Stand Up for the Burrup: Saving the Largest Aboriginal Rock Art Precinct in Australia

    2009-12-01

    Full Text Available The Dampier Rock Art Precinct contains the largest and most ancient collection of Aboriginal rock art in Australia. The cultural landscape created by generations of Aboriginal people includes images of long-extinct fauna and demonstrates the response of peoples to a changing climate over thousands of years as well as the continuity of lived experience. Despite Australian national heritage listing in 2007, this cultural landscape continues to be threatened by industrial development. Rock art on the eastern side of the archipelago, on the Burrup Peninsula, was relocated following the discovery of adjacent off-shore gas reserves so that a major gas plant could be constructed. Work has now begun on the construction of a second major gas plant nearby. This article describes the rock art of the Dampier Archipelago and the troubled history of European-Aboriginal contact history, before examining the impact of industry on the region and its environment. The destruction of Aboriginal rock art to meet the needs of industry is an example of continuing indifference to Aboriginal culture. While the complex struggle to protect the cultural landscape of the Burrup, in particular, involving Indigenous people, archaeologists, historians, state and federal politicians, government bureaucrats and multi-national companies, eventually led to national heritage listing, it is not clear that the battle to save the Burrup has been won.

    We consider the problem of distinguishing between different rates of percolation under noise. A statistical model of percolation is constructed allowing for the birth and death of edges as well as the presence of noise in the observations. This graph-valued stochastic process is composed of a latent and an observed nonstationary process, where the observed graph process is corrupted by type-I and type-II errors. This produces a hidden Markov graph model. We show that for certain choices of parameters controlling the noise, the classical (Erdős-Rényi) percolation is visually indistinguishable from a more rapid form of percolation. In this setting, we compare two different criteria for discriminating between these two percolation models, based on the interquartile range (IQR) of the first component's size, and on the maximal size of the second-largest component. We show through data simulations that this second criterion outperforms the IQR of the first component's size, in terms of discriminatory power. The maximal size of the second component therefore provides a useful statistic for distinguishing between different rates of percolation, under physically motivated conditions for the birth and death of edges, and under noise. The potential application of the proposed criteria for the detection of clinically relevant percolation in the context of applied neuroscience is also discussed.

    The Neotropics harbour the most diverse flora and fauna on Earth. The Andes are a major centre of diversification and source of diversity for adjacent areas in plants and vertebrates, but studies on insects remain scarce, even though they constitute the largest fraction of terrestrial biodiversity. Here, we combine molecular and morphological characters to generate a dated phylogeny of the butterfly genus Pteronymia (Nymphalidae: Danainae), which we use to infer spatial, elevational and temporal diversification patterns. We first propose six taxonomic changes that raise the generic species total to 53, making Pteronymia the most diverse genus of the tribe Ithomiini. Our biogeographic reconstruction shows that Pteronymia originated in the Northern Andes, where it diversified extensively. Some lineages colonized lowlands and adjacent montane areas, but diversification in those areas remained scarce. The recent colonization of lowland areas was reflected by an increase in the rate of evolution of species’ elevational ranges towards present. By contrast, speciation rate decelerated with time, with no extinction. The geological history of the Andes and adjacent regions have likely contributed to Pteronymia diversification by providing compartmentalized habitats and an array of biotic and abiotic conditions, and by limiting dispersal between some areas while promoting interchange across others.

    The objective of this study was to investigate the patient and staff doses in the most frequent interventional cardiology (IC) procedures performed in Onassio, the largest Cardiac Centre in Greece. Data were collected from three digital X-ray systems for 212 coronary angiographies, 203 percutaneous transluminal coronary angio-plasties (PTCA) and 134 various electrophysiological studies. Patient skin dose was measured using suitably calibrated slow radiotherapy films and cardiologist dose using suitably calibrated thermoluminescent dosemeters placed on left arm, hand and foot. Patient median dose area product (DAP) (all examinations) ranged between 6.7 and 83.5 Gy cm 2 . Patient median skin dose in PTCA was 799 mGy (320-1660 mGy) and in RF ablation 160 mGy (35-1920 mGy). Median arm, hand and foot dose to the cardiologist were 12.6, 27 and 13 μSv, respectively, per procedure. The great range of radiation doses received by both patients and operators confirms the need for continuous monitoring of all IC techniques. (authors)

  18. DISCOVERY OF THE LARGEST KNOWN LENSED IMAGES FORMED BY A CRITICALLY CONVERGENT LENSING CLUSTER

    We identify the largest known lensed images of a single spiral galaxy, lying close to the center of the distant cluster MACS J1149.5+2223 (z = 0.544). These images cover a total area of ≅150 mbox '' and are magnified ≅200 times. Unusually, there is very little image distortion, implying that the central mass distribution is almost uniform over a wide area (r ≅ 200 kpc) with a surface density equal to the critical density for lensing, corresponding to maximal lens magnification. Many fainter multiply lensed galaxies are also uncovered by our model, outlining a very large tangential critical curve, of radius r ≅ 170 kpc, posing a potential challenge for the standard LCDM cosmology. Because of the uniform central mass distribution, a particularly clean measurement of the mass of the brightest cluster galaxy is possible here, for which we infer stars contribute most of the mass within a limiting radius of ≅30 kpc, with a mass-to-light ratio of M/L B ≅ 4.5(M/L) sun . This cluster with its uniform and central mass distribution acts analogously to a regular magnifying glass, converging light without distorting the images, resulting in the most powerful lens yet discovered for accessing the faint high-z universe.

    This study was conducted to estimate the prevalence and molecular epidemiological features of viral hepatitis A, B and C in the Kalunga population, which represents the largest Afro-Brazilian isolated community. Among 878 individuals studied, the overall prevalence of anti-hepatitis A virus antibodies was 80.9%, with a significant rise from 44.8% to near 100% between the first and fourth decade of life. Rates for hepatitis B surface antigen (HBsAg) and antibody to hepatitis B core antigen (anti-HBc) of 1.8% and 35.4%, respectively, were found. Increasing age, male gender, illiteracy and history of multiple sexual partners were associated with hepatitis B virus (HBV) infection. An occult HBV infection rate of 1.7% (5/295) was found among anti-HBc-positive individuals. HBV genotype A (subtype Aa) was dominant in this community. Only 5/878 individuals (0.6%) were positive for anti-hepatitis C virus (HCV). HCV RNA was detected in three of them, who were infected with genotype 1 (subtype 1a). These findings point out high, intermediate and low endemicity for hepatitis A, B and C, respectively, in the Kalunga community in Brazil. Circulation of HBV genotype A (subtype Aa) in this Afro-Brazilian isolated community indicates the introduction of this virus during the slave trade from Africa to Brazil.

  20. Bubble nucleation in simple and molecular liquids via the largest spherical cavity method

    Gonzalez, Miguel A.; Abascal, José L. F.; Valeriani, Chantal; Bresme, Fernando

    2015-01-01

    In this work, we propose a methodology to compute bubble nucleation free energy barriers using trajectories generated via molecular dynamics simulations. We follow the bubble nucleation process by means of a local order parameter, defined by the volume of the largest spherical cavity (LSC) formed in the nucleating trajectories. This order parameter simplifies considerably the monitoring of the nucleation events, as compared with the previous approaches which require ad hoc criteria to classify the atoms and molecules as liquid or vapor. The combination of the LSC and the mean first passage time technique can then be used to obtain the free energy curves. Upon computation of the cavity distribution function the nucleation rate and free-energy barrier can then be computed. We test our method against recent computations of bubble nucleation in simple liquids and water at negative pressures. We obtain free-energy barriers in good agreement with the previous works. The LSC method provides a versatile and computationally efficient route to estimate the volume of critical bubbles the nucleation rate and to compute bubble nucleation free-energies in both simple and molecular liquids

    The Mekong delta is the third's largest delta in the world. It is home to almost 20 million people and an important region for the food security in South East Asia. As most deltas, the Mekong delta is the dynamic result of a balance of sediment supply, sea level rise and subsidence, hosting a system of fresh and salt water dynamics. Ongoing urbanization, industrialization and intensification of agricultural practices in the delta, during the past decades, resulted in growing domestic, agricultural and industrial demands, and have led to a dramatic increase of fresh water use. Since the year 2000, the amount of fresh groundwater extracted from the subsurface increased by 500%. This accelerated delta subsidence as the groundwater system compacts, with current sinking rates exceeding global sea level rise up to an order of magnitude. These high sinking rates have greatly altered the sediment budget of the delta and, with over 50% of the Mekong delta surface elevated less than 1 meter above sea level, greatly increase vulnerability to flooding and storm surges and ultimately, permanent inundation. Furthermore, as the increasingly larger extractions rapidly reduce the fresh groundwater reserves, groundwater salinization subsequently increases. On top of that, dry season low-flows by the Mekong river cause record salt water intrusion in the delta's estuarine system, creating major problems for rice irrigation. We present the work of three years research by the Dutch-Vietnamese `Rise and Fall' project on land subsidence and salinization in both groundwater and surface water in the Vietnamese Mekong delta.

    Full Text Available Given the current macroeconomic environment experienced in Brazil, where inflation has stabilized and the basic interest rate of the economy is in one of their historical lows, demand for mortgages is increasing. In this context, the mortgage is presented with great emphasis to meet the demand for purchasing housing in addition to being a catalyst for the reduction of the high housing deficit. From a descriptive and empirical-analytic was analyzed the mortgage loan portfolio of the largest banks of the country between the years 2001 and 2010 through Quarterly Financial Information (IFT available on the Central Bank website. It was settled a comparative relationship between the data in order to check the development of mortgage portfolios over the years and the factors that influenced this evolution, and evaluate the timeliness and quality of those loans. For the evolution of the portfolio there was an economic context in which Brazil was included in the period, and observed that for most of these operations are long term the banks are more exposed to market risk. With regard to credit risk parse that, over the years, Brazilian banks are presenting a mortgage loan portfolio with lower risk, and it is found that institutions with real estate credits with higher levels of portfolio risk are subject to have higher losses on such operations in the possibility of default.

    Full Text Available Corporate social responsibility has become an important concept in the business world in recent decades. CSR is important in all countries but is particularly relevant in emerging markets where the levels of human development are not high. The United Nations Development Programme has created the Human Development Index (HDI to measure the human development in countries. The present study analyzes the CSR communication on the websites of the 100 largest Indian companies. The objective was to examine the reported CSR activities and determine whether the activities address the dimensions and indicators of the HDI. The study uses content analysis to classify the CSR activities into categories corresponding to HDI parameters. The findings indicate that about two thirds of the companies are using their websites to communicate CSR. Of the companies which reported CSR, about eighty percent report support for primary education and about seventy percent undertake livelihood support activities. The level of corporate involvement in the health dimension of human development is quite low. Reduction of infant and maternal mortality does not get much corporate attention. This study will add to the literature on CSR in emerging markets and will be useful for firms in India and other emerging markets that are planning CSR activities aimed at human development parameters.

    Full Text Available This study evaluates the influence of the largest Serbian coal-fired power plant on radionuclide concentrations in soil profiles up to 50 cm in depth. Thirty soil profiles were sampled from the plant surroundings (up to 10 km distance and analyzed using standard methods for soil physicochemical properties and gamma ray spectrometry for specific activities of natural radionuclides (40K, 226Ra and 232Th. Spatial and vertical distribution of radionuclides was determined and analyzed to show the relations between the specific activities in the soil and soil properties and the most influential factors of natural radionuclide variability were identified. The radiological indices for surface soil were calculated and radiological risk assessment was performed. The measured specific activities were similar to values of background levels for Serbia. The sampling depth did not show any significant influence on specific activities of natural radionuclides. The strongest predictor of specific activities of the investigated radionuclides was soil granulometry. All parameters of radiological risk assessment were below the recommended values and adopted limits. It appears that the coal-fired power plant does not have a significant impact on the spatial and vertical distribution of natural radionuclides in the area of interest, but technologically enhanced natural radioactivity as a consequence of the plant operations was identified within the first 1.5 km from the power plant.

    A new multituberculate, Yubaartar zhongyuanensis gen. and sp. nov., is reported from the Upper Cretaceous of Luanchuan County, Henan Province, China. The holotype of the new taxon is a partial skeleton with nearly complete cranium and associated lower jaws with in situ dentitions. The new species is the southern-most record of a Late Cretaceous multituberculate from outside of the Mongolian Plateau in Asia and represents the largest known Mesozoic multituberculate from Eurasia. The new specimen displays some intriguing features previously unknown in multituberculates, such as the first evidence of replacement of the ultimate upper premolar and a unique paleopathological case in Mesozoic mammals in which the animal with a severely broken right tibia could heal and survive in natural condition. The phylogenetic analysis based on craniodental characters places Yubaartar as the immediate outgroup of Taeniolabidoidea, a group consisting of a North American clade and an Asian clade. This relationship indicates at least a faunal interchange of multituberculates before the K-Pg transition. The new evidence further supports the hypothesis that disparity in dental complexity, which relates to animal diets, increased with generic richness and disparity in body size, and that an adaptive shift towards increased herbivory across the K-Pg transitional interval.

    Phylogenetic relationships and patterns of evolution within Melanerpes, one of the most diverse groups of New World woodpeckers (22-23 lineages), have been complicated due to complex plumages and morphological adaptations. In an attempt to resolve these issues, we obtained sequence data from four nuclear introns and two mitochondrial protein-coding genes for 22 of the 24 currently recognized species in the genus. We performed phylogenetic analyses involving Maximum Likelihood and Bayesian Inference, species-tree divergence dating, and biogeographic reconstructions. Tree topologies from the concatenated and species-tree analyses of the mtDNA and nDNA showed broadly similar patterns, with three relatively well-supported groups apparent: (a) the Sphyrapicus clade (four species); (b) the typical Melanerpes clade, which includes temperate and subtropical dry forest black-backed species; and (c) the mostly barred-backed species, here referred to as the "Centurus" clade. The phylogenetic position of Melanerpes superciliaris regarding the rest of Melanerpes is ambiguous as it is recovered as sister to the rest of Melanerpes or as sister to a group including Sphyrapicus+Melanerpes. Our species tree estimations recovered the same well-delimited highly-supported clades. Geographic range evolution (estimated in BioGeoBEARS) was best explained by a DIVALIKE+j model, which includes vicariance, founder effect speciation, and anagenetic dispersal (range expansion) as important processes involved in the diversification of the largest radiation of woodpeckers in the New World.

  7. Psyche's UV Reflectance Spectra: Exploring the origins of the largest exposed-core metallic asteroid

    2016-10-01

    (16) Psyche is the largest of the M-class asteroids, and is presumed to be the exposed core of a differentiated asteroid stripped of its mantle through hit-and-run collisions. However, other origins for Psyche have been proposed, including that it formed from a highly-reduced, metal rich material in the inner solar system or that its surface is olivine that has been space weathered. If (16) Psyche is an exposed core, then studying its properties enhances our understanding of the cores of all terrestrial planets, including the Earth's. If it accreted in the inner part of the solar system and was later injected into the asteroid belt, then Psyche sheds light on the conditions and subsequent evolution of the early solar system. Lastly, if Psyche is weathered olivine, then olivine may be more abundant in the solar system than currently measured, rectifying the so-called Great Dunite Shortage. Our program to obtain high-resolution UV spectra of Psyche with the COS G140L mode and the STIS NUV MAMA G230L mode to measure spectral signatures between 90 - 315 nm is designed to distinguish between the 3 hypothesized cases. These observations will enable identification of absorption bands, especially Fe-O charge transfer bands and will be sensitive to spectral blueing that occurs at UV wavelengths for space-weathered objects. When combined, the presence of these UV features, or not, provides a novel test of Psyche formation theories.

    Nowadays, the new international market demands challenge the food producing countries to include the measurement of the environmental impact generated along the production process for their products. In order to comply with the environmentally responsible market requests the measurement of the greenhouse gas emissions of Ecuadorian agricultural goods has been promoted employing the carbon footprint concept. Ecuador is the largest exporter of bananas in the world. Within this context, this study is a first assessment of the carbon footprint of the Ecuadorian premium export banana (Musa AAA) using a considerable amount of field data. The system boundaries considered from agricultural production to delivery in a European destination port. The data collected over three years permitted identifying the hot spot stages. For the calculation, the CCaLC V3.0 software developed by the University of Manchester is used. The carbon footprint of the Ecuadorian export banana ranged from 0.45 to 1.04 kg CO2-equivalent/kg banana depending on the international overseas transport employed. The principal contributors to the carbon footprint are the on farm production and overseas transport stages. Mitigation and reduction strategies were suggested for the main emission sources in order to achieve sustainable banana production. Copyright © 2013 Elsevier B.V. All rights reserved.

    Wild grapevine is becoming a threatened species in the Iberian Peninsula due to human impacts. The aim of this work was to carry out a holistic study for six years of the largest wild grapevine population found up to date in SW Iberian Peninsula. This population has 115 vines. Ampelographic and soil characteristics have been studied. Evaluation of its environment has also been studied by describing the main parasitic species and natural enemies of pests. The ability of this plant material for its micropropagation and storage in slow-growth conditions has been tested. Microvinification resulted in a wine with good acidity and medium color intensity, two interesting characteristics under a warm climatology. Finally, the identification of private alleles in this wild population, absent in other locations from the Northern and Southern Iberian territories, is a very valuable feature and confirms the importance of establishing conservation programs. The population here studied is genetically unique and potentially useful for commercial rootstocks and cultivars breeding that would improve viticulture and enology. (Author)

    Because state-owned oil and gas companies dominate Oil and Gas Journal's list of largest non-US producers, data aren't fully comparable with those of the OGJ300. Many state companies report only production and reserves, with little or no financial data. Companies on the OGJ100, therefore, cannot be ranked by assets or revenues. Instead, they are listed by regions, based on location of corporate headquarters. There was no change in makeup of the top 20 holders of crude oil reserves. These companies' reserves totaled 872.3 billion bbl in 1993. The top 20 non-US companies now control 87.3 % of total world crude oil reserves, according to OGJ estimates. This is up marginally from 87.2 % of total world oil reserves in 1992. The top 20 had 87.7 % of total world reserves in 1991 and 85.5 % in 1990. The table lists company name, total assets, revenues, net income, capital and exploratory expenditures, worldwide oil production, gas production, oil and gas reserves worldwide

The article presents the experience to assess social responsibility of business on the example of the largest chemical enterprises located in the Vologda and Novgorod oblasts. The evaluation results have revealed a number of problems hindering the formation of socially responsible behavior of enterprises, particularly the lack of standardized reporting on corporate social responsibility; provision of formal corporate social responsibility report; business’ non-system participation in social and economic development of territories. According to the authors, the development of a special model to regulate participants’ mutual relations can increase social responsibility of Russian business. Unified interests and resources of business and government promote the development of an agreed strategy in the field of regional social-economic development

    Zebra mussel (Dreissena polymorpha) has been used for the biomonitoring of several POPs (PCBs, DDTs, HCB and HCHs) in the largest Italian subalpine great lakes (Lake Maggiore, Garda, Como, Iseo and Lugano). Samplings were carried out in April 2003 at 15 locations selected according to industrial and anthropic levels of lakes. Results have pointed out high DDT levels in D. polymorpha specimens from Lake Maggiore (700-1400 ng/g lipids, 5-9 times higher than those measured in mussels of other Italian lakes), due to a contamination from a chemical plant located on one of the main lake inlet that occurred in 1996. On the contrary, PCB levels (400-2509 ng/g lipids) highlighted an overall pollution, with some sporadic peaks of contamination. Data showed a moderate increase trend compared to those found in a previous monitoring campaign carried out in 1996. Future monitoring is needed in order to confirm this tendency. - Significant levels of DDTs and PCBs are still present in the Italian subalpine great lakes

    Full Text Available This study evaluated pollution levels in water and sediments of Península de Paraguaná and related these levels with benthic macrofauna along a coastal area where the largest Venezuelan oil refineries have operated over the past 60 years. For this, the concentration of heavy metals, of hydrocarbon compounds and the community structure of the macrobenthos were examined at 20 sites distributed along 40 km of coastline for six consecutive years, which included windy and calm seasons. The spatial variability of organic and inorganic compounds showed considerably high coastal pollution along the study area, across both years and seasons. The southern sites, closest to the refineries, had consistently higher concentrations of heavy metals and organic compounds in water and sediments when compared to those in the north. The benthic community was dominated by polychaetes at all sites, seasons and years, and their abundance and distribution were significantly correlated with physical and chemical characteristics of the sediments. Sites close to the oil refineries were consistently dominated by families known to tolerate xenobiotics, such as Capitellidae and Spionidae. The results from this study highlight the importance of continuing long-term environmental monitoring programs to assess the impact of effluent discharge and spill events from the oil refineries that operate in the western coast of Paraguaná, Venezuela.

    Full Text Available China’s largest freshwater lake, Poyang Lake, is characterized by rapid changes in its inundation area and hydrodynamics, so in this study, a hydrodynamic model of Poyang Lake was established to simulate these long-term changes. Inundation information was extracted from Moderate Resolution Imaging Spectroradiometer (MODIS remote sensing data and used to calibrate the wetting and drying parameter by assessing the accuracy of the simulated inundation area and its boundary. The bottom friction parameter was calibrated using current velocity measurements from Acoustic Doppler Current Profilers (ADCP. The results show the model is capable of predicting the inundation area dynamic through cross-validation with remotely sensed inundation data, and can reproduce the seasonal dynamics of the water level, and water discharge through a comparison with hydrological data. Based on the model results, the characteristics of the current velocities of the lake in the wet season and the dry season of the lake were explored, and the potential effect of the current dynamic on water quality patterns was discussed. The model is a promising basic tool for prediction and management of the water resource and water quality of Poyang Lake.

    The surface of Earth is a dynamic and permeable interface where the rocky crust is sculpted by ice, wind and water resulting in spectacular mountain ranges, vast depositional basins and environments that support life. These landforms and deposits contain a rich, yet incomplete, record of Earth history that we are just beginning to understand. Some of the most dramatic landforms are the huge bedrock canyons carved by catastrophic floods. On Mars, similar bedrock canyons, known as Outflow Channels, are the most important indicators of large volumes of surface water in the past. Despite their importance and now decades of observations of canyon morphology, we lack a basic understanding of how the canyons formed, which limits our ability to reconstruct flood discharge, duration and water volume. In this presentation I will summarize recent work - using mechanistic numerical models and field observations - that suggests that bedrock canyons carved by megafloods rapidly evolve to a size and shape such that boundary shear stresses just exceed that required to entrain fractured blocks of rock. The threshold shear stress constraint allows for quantitative reconstruction of the largest known floods on Earth and Mars, and implies far smaller discharges than previous methods that assume flood waters fully filled the canyons to high water marks.

    We report the discovery of a new Kepler transiting circumbinary planet (CBP). This latest addition to the still-small family of CBPs defies the current trend of known short-period planets orbiting near the stability limit of binary stars. Unlike the previous discoveries, the planet revolving around the eclipsing binary system Kepler-1647 has a very long orbital period (∼1100 days) and was at conjunction only twice during the Kepler mission lifetime. Due to the singular configuration of the system, Kepler-1647b is not only the longest-period transiting CBP at the time of writing, but also one of the longest-period transiting planets. With a radius of 1.06 ± 0.01 R Jup , it is also the largest CBP to date. The planet produced three transits in the light curve of Kepler-1647 (one of them during an eclipse, creating a syzygy) and measurably perturbed the times of the stellar eclipses, allowing us to measure its mass, 1.52 ± 0.65 M Jup . The planet revolves around an 11-day period eclipsing binary consisting of two solar-mass stars on a slightly inclined, mildly eccentric ( e bin = 0.16), spin-synchronized orbit. Despite having an orbital period three times longer than Earth’s, Kepler-1647b is in the conservative habitable zone of the binary star throughout its orbit.

    Precipitation samples were collected from March 2010 to August 2012 at an urban site in Lhasa, the capital and largest city of Tibet. The volume weighted mean (VWM) concentrations of 17 trace elements in precipitation were higher during the non-monsoon season than in the monsoon season, but inverse seasonal variations occurred for wet deposition fluxes of most of the trace elements. Concentrations for most of trace elements were negatively correlated with precipitation amount, indicating that below-cloud scavenging of trace elements was an important mechanism contributing to wet deposition of these elements. The elements Al, Sc, V, Cr, Mn, Fe, Mn, Ni, and U displayed low crustal enrichment factors (EFs), whereas Co, Cu, Zn, As, Cd Sn, Pb, and Bi showed high EF values in precipitation, suggesting that anthropogenic activities might be important contributors of these elements at Lhasa. However, this present work indicates a much lower anthropogenic emission at Lhasa than in seriously polluted regions. Our study will not only provide insights for assessing the current status of the atmospheric environment in Lhasa but also enhance our understanding for updating the baseline for environmental protection over the Tibetan Plateau.

    A subsea hot tap was conducted near the gas production platforms in Angel Field, Australia in September 2007 and verified as the largest no. 900 subsea hot tap by Australian authorities. This paper outlines the subsea tapping process, risks and safety issues in deep water environment, including the need to ensure 100% system accuracy and that the machine fluids used to operate the subsea tapping machines were environmentally friendly. The testing phase included land and water testing. In the land tests, issues relating to metal hardness, temperature, pressure and ocean currents that affected machine stability, torque and cutting rate were considered. All preliminary design and testing focused on being able to mount the tapping machine to a pre-existing hot-tap flange and conduct the tapping operation, start to finish, preferably without changing the cutter. The water depth tests took place inside a pressurized, underwater hyperbaric chamber. The equipment repeated the land testing process in conditions duplicating that of the actual project site. Timing was also measured in multiple climatic conditions (except water depth) to obtain an estimation of various scenarios. The field tapping process was conducted without problems in over six hours with a single cutter and without any stalls. (author)

    Full Text Available Dragon Bridge - The world’s largest dragon-shaped steel bridge, with an installation cost of $85 million USD, features 6 lanes for two separate directions, 666 meters of undulating steel in the shape of a dragon in the Ly Dynasty, the symbol of prosperity in Vietnamese culture. This unique and beautifully lit bridge, which also breathes fire and sprays water. It’s the purposeful integration of the lighting hardware articulates the dragon’s form, and the fire-breathing dragon head. This project transcends the notion of monumental bridge with dynamic colour-changing lighting, creating an iconic sculpture in the skyline that is both reverent and whimsical. The signature feature of the bridge was the massive undulating support structure resembling a dragon flying over the river. The dragon is prominent in Vietnamese culture as a symbol of power and nobility. Dragon Bridge stands out as a model of innovation. It has received worldwide attention in the design community and from the global media for its unique arch support system. Dragon Bridge serves as an example of how aesthetic quality of a design can serve cultural, economic and functional purposes. The article presents design solutions of the object and the evaluation of the technical condition before putting the facility into service.

    Astronomers have unveiled an unprecedented new atlas of the inner regions of the Milky Way, our home galaxy, peppered with thousands of previously undiscovered dense knots of cold cosmic dust -- the potential birthplaces of new stars. Made using observations from the APEX telescope in Chile, this survey is the largest map of cold dust so far, and will prove an invaluable map for observations made with the forthcoming ALMA telescope, as well as the recently launched ESA Herschel space telescope.

Images of the cosmos at these wavelengths are vital for studying the birthplaces of new stars and the structure of the crowded galactic core. "ATLASGAL gives us a new look at the Milky Way. Not only will it help us investigate how massive stars form, but it will also give us an overview of the larger-scale structure of our galaxy", said Frederic Schuller from the Max Planck Institute for Radio Astronomy, leader of the ATLASGAL team. The area of the new submillimetre map is approximately 95 square degrees, covering a very long and narrow strip along the galactic plane two degrees wide (four times the width of the full Moon) and over 40 degrees long.

    The Kalahari Basin in southern Africa - one of the largest basins in Africa, along with the Congo and Chad basins - has attracted attention since David Livingstone traveled through the area in the 1840s. It is a semiarid desert with a large freshwater swampland known as the Okavango Swamp (150 km radius). This prominent megafan (a fan with radii >100 km), with its fingers of dark green forests projecting into the dun colors of the dunes of the Kalahari semi-desert, has been well photographed by astronauts over the years. The study area in the northern Kalahari basin is centered on the Okavango megafan of northwest Botswana, whose swampland has become well known as an African wildlife preserve of importance to biology and tourism alike. The Okavango River is unusual because it has deposited not one but two megafans along its course: the Okavango megafan and the Cubango megafan. The Okavango megafan is one of only three well-known megafans in Africa. Megafans on Earth were once thought to be rare, but recent research has documented 68 in Africa alone. Eleven megafans, plus three more candidates, have been documented in the area immediately surrounding the Okavango feature. These 11 megafans occupy the flattest and smoothest terrains adjacent to the neighboring upland and stand out as the darkest areas in the roughness map of the area. Megafan terrains occupy at least 200,000 sq km of the study area. The roughness map shown is based on an algorithm used first on Mars to quantify topographic roughness. Research of Earth's flattest terrains is just beginning with the aid of such maps, and it appears that these terrains are analogous to the flattest regions of Mars. Implications: 1. The variability in depositional style in each subbasin may apply Africa-wide: rift megafan length is dominated by rift width, whereas Owambo subbasin megafans are probably controlled by upland basin size; Zambezi subbasin megafans appear more like foreland basin types, with the position of

    Sustainable pathways of land use for energy are necessary to mitigate climate change and limit conversion of finite land resources needed for conservation and food production. Large, commercial buildings (LCBs) are increasing in size and number throughout the United States (US) and may serve as suitable recipient environments for photovoltaic (PV) solar energy infrastructure that may support a low carbon, low land footprint energy transition. In this study, we identified, characterized, and evaluated the technical potential of the largest, commercial building rooftops (i.e., exceeding 110,000 m2) and their associated parking lots in the US for PV solar energy systems using Aurora, a cloud-based solar optimization platform. We also performed a case study of building-specific electricity generation: electricity consumption balance. Further, we quantified the environmental co-benefit of land sparing and associated avoided emissions (t-CO2-eq) conferred under the counterfactual scenario that solar development would otherwise proceed as a ground-mounted, utility-scale PV installation of equal nominal capacity. We identified and mapped 37 LCBs (by rooftop area) across 18 states in the US, spanning from as far north as the state of Minnesota to as far south as Florida. Rooftop footprints range from 427,297 to 113,689 m2 and have a cumulative surface area of 99.8 million ft2. We characterize the LCBs as either: distribution/warehouse, factory, shopping center, or administrative office/facility. Three of the 37 LCBs currently support rooftop PV and the numbers of associated, detached buildings number up to 38. This study elucidates the extent to which LCBs and their respective parking lots can serve as suitable sites for PV solar energy generation. Lastly, this study demonstrates research-based applications of the Aurora energy modeling platform and informs decision-making focused on redirecting energy development towards human-modified landscapes to prioritize land use for

    Efficient modes of extracorporeal blood purification are available today for apheresis treatment of progressive atherosclerosis, autoimmune disease, or for improving hemorheology. Advanced technology and sophisticated care render apheresis treatment selective, safe and tolerable. Our task is to constantly update indications for apheresis based on best evidence available and good clinical practice, as well as, to determine how apheresis therapy can be made available to those in need or with otherwise refractory disease. Presenting examples of lipid apheresis, rheopheresis, or immunoadsorption for treatment of hypercholesterolemia, hyperlipoproteinemia (a), acute hearing loss, refractory or exacerbating multiple sclerosis, we highlight real world obstacles for implementation of treatment, resulting in still too many patients with proven or recommended indication left untreated. Based on the experience of the largest apheresis center in Germany, with more than 3,300 treatments per year, we depict the necessary structure for identification of patients, defining indication, referral, implementation of therapy, and reimbursement. Apheresis is unfamiliar to most patients and many practitioners or consultants. Nephrologists, performing >90% of apheresis treatments in Germany, have to form a network for referral comprising all regional care-givers, general practitioners as well as the respective specialists (mainly, cardiologists, endocrinologists, diabetologists, ORL specialists, neurologists, ophthalmologists, or rheumatologists), and insurances or other cost-bearing parties for offering a scientifically approved therapeutic regimen and comprehensive care. We have realized this concept in a high volume apheresis center acting in a closely knit network characterized by an unrelenting effort at ongoing medical education. As a consequence, we include approximately 10 times more patients with appropriate diagnoses in our apheresis program as compared to the national average

  5. Evidence for protection of targeted reef fish on the largest marine reserve in the Caribbean

    Full Text Available Marine reserves can restore fish abundance and diversity in areas impacted by overfishing, but the effectiveness of reserves in developing countries where resources for enforcement are limited, have seldom been evaluated. Here we assess whether the establishment in 1996 of the largest marine reserve in the Caribbean, Gardens of the Queen in Cuba, has had a positive effect on the abundance of commercially valuable reef fish species in relation to neighboring unprotected areas. We surveyed 25 sites, including two reef habitats (reef crest and reef slope, inside and outside the marine reserve, on five different months, and over a one-and-a-half year period. Densities of the ten most frequent, highly targeted, and relatively large fish species showed a significant variability across the archipelago for both reef habitats that depended on the month of survey. These ten species showed a tendency towards higher abundance inside the reserve in both reef habitats for most months during the study. Average fish densities pooled by protection level, however, showed that five out of these ten species were at least two-fold significantly higher inside than outside the reserve at one or both reef habitats. Supporting evidence from previously published studies in the area indicates that habitat complexity and major benthic communities were similar inside and outside the reserve, while fishing pressure appeared to be homogeneous across the archipelago before reserve establishment. Although poaching may occur within the reserve, especially at the boundaries, effective protection from fishing was the most plausible explanation for the patterns observed.

  6. Phylogenetics and diversification of tanagers (Passeriformes: Thraupidae), the largest radiation of Neotropical songbirds.

    Thraupidae is the second largest family of birds and represents about 4% of all avian species and 12% of the Neotropical avifauna. Species in this family display a wide range of plumage colors and patterns, foraging behaviors, vocalizations, ecotypes, and habitat preferences. The lack of a complete phylogeny for tanagers has hindered the study of this evolutionary diversity. Here, we present a comprehensive, species-level phylogeny for tanagers using six molecular markers. Our analyses identified 13 major clades of tanagers that we designate as subfamilies. In addition, two species are recognized as distinct branches on the tanager tree. Our topologies disagree in many places with previous estimates of relationships within tanagers, and many long-recognized genera are not monophyletic in our analyses. Our trees identify several cases of convergent evolution in plumage ornaments and bill morphology, and two cases of social mimicry. The phylogeny produced by this study provides a robust framework for studying macroevolutionary patterns and character evolution. We use our new phylogeny to study diversification processes, and find that tanagers show a background model of exponentially declining diversification rates. Thus, the evolution of tanagers began with an initial burst of diversification followed by a rate slowdown. In addition to this background model, two later, clade-specific rate shifts are supported, one increase for Darwin's finches and another increase for some species of Sporophila. The rate of diversification within these two groups is exceptional, even when compared to the overall rapid rate of diversification found within tanagers. This study provides the first robust assessment of diversification rates for the Darwin's finches in the context of the larger group within which they evolved. Copyright © 2014 Elsevier Inc.

  7. Invertebrate population genetics across Earth's largest habitat: The deep-sea floor.

    Taylor, M L; Roterman, C N

    2017-10-01

    Despite the deep sea being the largest habitat on Earth, there are just 77 population genetic studies of invertebrates (115 species) inhabiting non-chemosynthetic ecosystems on the deep-sea floor (below 200 m depth). We review and synthesize the results of these papers. Studies reveal levels of genetic diversity comparable to shallow-water species. Generally, populations at similar depths were well connected over 100s-1,000s km, but studies that sampled across depth ranges reveal population structure at much smaller scales (100s-1,000s m) consistent with isolation by adaptation across environmental gradients, or the existence of physical barriers to connectivity with depth. Few studies were ocean-wide (under 4%), and 48% were Atlantic-focused. There is strong emphasis on megafauna and commercial species with research into meiofauna, "ecosystem engineers" and other ecologically important species lacking. Only nine papers account for ~50% of the planet's surface (depths below 3,500 m). Just two species were studied below 5,000 m, a quarter of Earth's seafloor. Most studies used single-locus mitochondrial genes revealing a common pattern of non-neutrality, consistent with demographic instability or selective sweeps; similar to deep-sea hydrothermal vent fauna. The absence of a clear difference between vent and non-vent could signify that demographic instability is common in the deep sea, or that selective sweeps render single-locus mitochondrial studies demographically uninformative. The number of population genetics studies to date is miniscule in relation to the size of the deep sea. The paucity of studies constrains meta-analyses where broad inferences about deep-sea ecology could be made. © 2017 The Authors. Molecular Ecology Published by John Wiley & Sons Ltd.

    Full Text Available Background: The present study aimed to determine attitudes and effective factors in the acceptance of smart phones by physicians of the largest University of Medical Sciences in the south of Iran. Methods: This cross-sectional study was performed using Structural Equation Modelling (SEM in 2014. Study participants included 200 physicians working in the hospitals of Shiraz University of Medical Sciences selected through two-stage stratified sampling, but 185 participants completed the study. The study data were collected using a researcher-made questionnaire completed through a 5-point Likert scale. The content validity of the questionnaire was confirmed by a panel of experts, its construct validity by confirmatory factor analysis, and its reliability by Cronbach’s alpha of 0.802. All data analyses were performed using SPSS (version 22 and LISREL (version 8.8. Results: Results showed that most physicians had a desirable attitude towards using smart phones. Besides, the results of SEM indicated a significant relationship between attitude and compatibility, observability, personal experience, voluntariness of use and perceived usefulness. Moreover, some important fitness indices revealed appropriate fitness of the study model (p=0.26, X2 /df=1.35, RMR=0.070, GFI=0.77, AGFI=0.71, NNFI=0.93, CFI=0.94. Conclusion: The results revealed that compatibility, observability, personal experience, voluntariness of use and perceived usefulness were effective in the physicians’ attitude towards using smart phones. Thus, by preparation of the required infrastructures, policymakers in the field of health technology can enhance the utilization of smart phones in hospitals.

    Vancouver's Downtown Eastside is home to Canada's largest street-based drug scene and only supervised injection facility (Insite). High levels of violence among men and women have been documented in this neighbourhood. This study was undertaken to explore the role of violence in shaping the socio-spatial relations of women and 'marginal men' (i.e., those occupying subordinate positions within the drug scene) in the Downtown Eastside, including access to Insite. Semi-structured qualitative interviews were conducted with 23 people who inject drugs (PWID) recruited through the Vancouver Area Network of Drug Users, a local drug user organization. Interviews included a mapping exercise. Interview transcripts and maps were analyzed thematically, with an emphasis on how gendered violence shaped participants' spatial practices. Hegemonic forms of masculinity operating within the Downtown Eastside framed the everyday violence experienced by women and marginal men. This violence shaped the spatial practices of women and marginal men, in that they avoided drug scene milieus where they had experienced violence or that they perceived to be dangerous. Some men linked their spatial restrictions to the perceived 'dope quality' of neighbourhood drug dealers to maintain claims to dominant masculinities while enacting spatial strategies to promote safety. Environmental supports provided by health and social care agencies were critical in enabling women and marginal men to negotiate place and survival within the context of drug scene violence. Access to Insite did not motivate participants to enter into "dangerous" drug scene milieus but they did venture into these areas if necessary to obtain drugs or generate income. Gendered violence is critical in restricting the geographies of men and marginal men within the street-based drug scene. There is a need to scale up existing environmental interventions, including supervised injection services, to minimize violence and potential drug

There is a need to scale up existing environmental interventions, including supervised injection

    Lake Três Irmãs (LTI), the largest upland lake in the Brazilian Amazonia, located in Serra dos Carajás, was characterized using multi-elemental and isotope geochemistry (δ13C and δ15N) to understand the significance of organic and inorganic sources, weathering and sedimentary processes on the distribution of elements in lake bottom (surficial) sediments. Carbon and nitrogen isotopes from sedimentary organic matter suggest C3 terrestrial plants (forests > canga vegetation), macrophytes and freshwater DOC as the main sources. Sediments are depleted in most of the major oxides (except Fe2O3 and P2O5) when compared to upper continental crust (UCC) and their spatial distribution is highly influenced by catchment lithology. Principal Component Analysis revealed that most of the trace elements (Ba, Sr, Rb, Sc, Th, U, Zr, Hf, Nb, Y, V, Cr, Ga, Co, Ni) and REEs are closely correlated with Al and Ti (PC1; Group-1), so their redistribution is less influenced by post-depositional process. This is due to their relative immobility and being hosted by Al-bearing minerals during laterization. High Chemical Index of Alteration (CIA), Mafic Index of Alteration (MIA) and Index of Laterization (IOL) values indicate intense chemical weathering at source areas, but the weathering transformation was better quantified by IOL. A-CN-K plot along with elemental ratios (Al/K, Ti/K, Ti/Zr, La/Al, Cr/Th, Co/Th, La/Sm, La/Gd, Zr/Y, and Eu/Eu*) as well as chondrite-normalized REE patterns show that the detritic sediments are mainly sourced from ferruginous laterites and soils in the catchment, which may have characteristics similar to mafic rocks.

    This study aimed to determine the effect of added noise, filtering and time series length on the largest Lyapunov exponent (LyE) value calculated for time series obtained from a passive dynamic walker. The simplest passive dynamic walker model comprising of two massless legs connected by a frictionless hinge joint at the hip was adopted to generate walking time series. The generated time series was used to construct a state space with the embedding dimension of 3 and time delay of 100 samples. The LyE was calculated as the exponential rate of divergence of neighboring trajectories of the state space using Rosenstein's algorithm. To determine the effect of noise on LyE values, seven levels of Gaussian white noise (SNR=55-25dB with 5dB steps) were added to the time series. In addition, the filtering was performed using a range of cutoff frequencies from 3Hz to 19Hz with 2Hz steps. The LyE was calculated for both noise-free and noisy time series with different lengths of 6, 50, 100 and 150 strides. Results demonstrated a high percent error in the presence of noise for LyE. Therefore, these observations suggest that Rosenstein's algorithm might not perform well in the presence of added experimental noise. Furthermore, findings indicated that at least 50 walking strides are required to calculate LyE to account for the effect of noise. Finally, observations support that a conservative filtering of the time series with a high cutoff frequency might be more appropriate prior to calculating LyE. Copyright © 2017 Elsevier Ltd.

    The U.S. Department of Energy Richland Operations Office (RL), U.S. Environmental Protection Agency (EPA) and Washington Closure Hanford LLC (WCH) completed remediation of one of the largest waste sites in the U.S. Department of Energy complex. The waste site, 100-C-7, covers approximately 15 football fields and was excavated to a depth of 85 feet (groundwater). The project team removed a total of 2.3 million tons of clean and contaminated soil, concrete debris, and scrap metal. 100-C-7 lies in Hanford's 100 B/C Area, home to historic B and C Reactors. The waste site was excavated in two parts as 100-C-7 and 100-C-7:1. The pair of excavations appear like pit mines. Mining engineers were hired to design their tiered sides, with safety benches every 17 feet and service ramps which allowed equipment access to the bottom of the excavations. The overall cleanup project was conducted over a span of almost 10 years. A variety of site characterization, excavation, load-out and sampling methodologies were employed at various stages of remediation. Alternative technologies were screened and evaluated during the project. A new method for cost effectively treating soils was implemented - resulting in significant cost savings. Additional opportunities for minimizing waste streams and recycling were identified and effectively implemented by the project team. During the final phase of cleanup the project team applied lessons learned throughout the entire project to address the final, remaining source of chromium contamination. The C-7 cleanup now serves as a model for remediating extensive deep zone contamination sites at Hanford. (authors)

  14. HOT Faults", Fault Organization, and the Occurrence of the Largest Earthquakes

    2006-12-01

    We apply the concept of "Highly Optimized Tolerance" (HOT) for the investigation of spatio-temporal seismicity evolution, in particular mechanisms associated with largest earthquakes. HOT provides a framework for investigating both qualitative and quantitative features of complex feedback systems that are far from equilibrium and punctuated by rare, catastrophic events. In HOT, robustness trade-offs lead to complexity and power laws in systems that are coupled to evolving environments. HOT was originally inspired by biology and engineering, where systems are internally very highly structured, through biological evolution or deliberate design, and perform in an optimum manner despite fluctuations in their surroundings. Though faults and fault systems are not designed in ways comparable to biological and engineered structures, feedback processes are responsible in a conceptually comparable way for the development, evolution and maintenance of younger fault structures and primary slip surfaces of mature faults, respectively. Hence, in geophysical applications the "optimization" approach is perhaps more aptly replaced by "organization", reflecting the distinction between HOT and random, disorganized configurations, and highlighting the importance of structured interdependencies that evolve via feedback among and between different spatial and temporal scales. Expressed in the terminology of the HOT concept, mature faults represent a configuration optimally organized for the release of strain energy; whereas immature, more heterogeneous fault networks represent intermittent, suboptimal systems that are regularized towards structural simplicity and the ability to generate large earthquakes more easily. We discuss fault structure and associated seismic response pattern within the HOT concept, and outline fundamental differences between this novel interpretation to more orthodox viewpoints like the criticality concept. The discussion is flanked by numerical simulations of a

    Full Text Available BACKGROUND: The largest living lizard species, Varanus komodoensis Ouwens 1912, is vulnerable to extinction, being restricted to a few isolated islands in eastern Indonesia, between Java and Australia, where it is the dominant terrestrial carnivore. Understanding how large-bodied varanids responded to past environmental change underpins long-term management of V. komodoensis populations. METHODOLOGY/PRINCIPAL FINDINGS: We reconstruct the palaeobiogeography of Neogene giant varanids and identify a new (unnamed species from the island of Timor. Our data reject the long-held perception that V. komodoensis became a giant because of insular evolution or as a specialist hunter of pygmy Stegodon. Phyletic giantism, coupled with a westward dispersal from mainland Australia, provides the most parsimonious explanation for the palaeodistribution of V. komodoensis and the newly identified species of giant varanid from Timor. Pliocene giant varanid fossils from Australia are morphologically referable to V. komodoensis suggesting an ultimate origin for V. komodoensis on mainland Australia (>3.8 million years ago. Varanus komodoensis body size has remained stable over the last 900,000 years (ka on Flores, a time marked by major faunal turnovers, extinction of the island's megafauna, the arrival of early hominids by 880 ka, co-existence with Homo floresiensis, and the arrival of modern humans by 10 ka. Within the last 2000 years their populations have contracted severely. CONCLUSIONS/SIGNIFICANCE: Giant varanids were once a ubiquitous part of Subcontinental Eurasian and Australasian faunas during the Neogene. Extinction played a pivotal role in the reduction of their ranges and diversity throughout the late Quaternary, leaving only V. komodoensis as an isolated long-term survivor. The events over the last two millennia now threaten its future survival.

  16. Nature Appropriation and Associations with Population Health in Canada’s Largest Cities

    Full Text Available Earth is a finite system with a limited supply of resources. As the human population grows, so does the appropriation of Earth’s natural capital, thereby exacerbating environmental concerns such as biodiversity loss, increased pollution, deforestation and global warming. Such concerns will negatively impact human health although it is widely believed that improving socio-economic circumstances will help to ameliorate environmental impacts and improve health outcomes. However, this belief does not explicitly acknowledge the fact that improvements in socio-economic position are reliant on increased inputs from nature. Gains in population health, particularly through economic means, are disconnected from the appropriation of nature to create wealth so that health gains become unsustainable. The current study investigated the sustainability of human population health in Canada with regard to resource consumption or “ecological footprints” (i.e., the resources required to sustain a given population. Ecological footprints of the 20 largest Canadian cities, along with several important determinants of health such as income and education, were statistically compared with corresponding indicators of human population health outcomes. A significant positive relationship was found between ecological footprints and life expectancy, as well as a significant negative relationship between ecological footprints and the prevalence of high blood pressure. Results suggest that increased appropriation of nature is linked to improved health outcomes. To prevent environmental degradation from excessive appropriation of natural resources will require the development of health promotion strategies that are de-coupled from ever-increasing and unsustainable resource use. Efforts to promote population health should focus on health benefits achieved from a lifestyle based on significantly reduced consumption of natural resources.

  17. Solomon Islands largest hawksbill turtle rookery shows signs of recovery after 150 years of excessive exploitation.

    Directory of Open Access Journals (Sweden)

    Richard J Hamilton

    Full Text Available The largest rookery for hawksbill turtles in the oceanic South Pacific is the Arnavon Islands, which are located in the Manning Strait between Isabel and Choiseul Province, Solomon Islands. The history of this rookery is one of overexploitation, conflict and violence. Throughout the 1800s Roviana headhunters from New Georgia repeatedly raided the Manning Strait to collect hawksbill shell which they traded with European whalers. By the 1970s the Arnavons hawksbill population was in severe decline and the national government intervened, declaring the Arnavons a sanctuary in 1976. But this government led initiative was short lived, with traditional owners burning down the government infrastructure and resuming intensive harvesting in 1982. In 1991 routine beach monitoring and turtle tagging commenced at the Arnavons along with extensive community consultations regarding the islands' future, and in 1995 the Arnavon Community Marine Conservation Area (ACMCA was established. Around the same time national legislation banning the sale of all turtle products was passed. This paper represents the first analysis of data from 4536 beach surveys and 845 individual turtle tagging histories obtained from the Arnavons between 1991-2012. Our results and the results of others, reveal that many of the hawksbill turtles that nest at the ACMCA forage in distant Australian waters, and that nesting on the Arnavons occurs throughout the year with peak nesting activity coinciding with the austral winter. Our results also provide the first known evidence of recovery for a western pacific hawksbill rookery, with the number of nests laid at the ACMCA and the remigration rates of turtles doubling since the establishment of the ACMCA in 1995. The Arnavons case study provides an example of how changes in policy, inclusive community-based management and long term commitment can turn the tide for one of the most charismatic and endangered species on our planet.

    The Spider system at the Oak Ridge National Laboratory's Leadership Computing Facility (OLCF) is the world's largest scale Lustre parallel file system. Envisioned as a shared parallel file system capable of delivering both the bandwidth and capacity requirements of the OLCF's diverse computational environment, the project had a number of ambitious goals. To support the workloads of the OLCF's diverse computational platforms, the aggregate performance and storage capacity of Spider exceed that of our previously deployed systems by a factor of 6x - 240 GB/sec, and 17x - 10 Petabytes, respectively. Furthermore, Spider supports over 26,000 clients concurrently accessing the file system, which exceeds our previously deployed systems by nearly 4x. In addition to these scalability challenges, moving to a center-wide shared file system required dramatically improved resiliency and fault-tolerance mechanisms. This paper details our efforts in designing, deploying, and operating Spider. Through a phased approach of research and development, prototyping, deployment, and transition to operations, this work has resulted in a number of insights into large-scale parallel file system architectures, from both the design and the operational perspectives. We present in this paper our solutions to issues such as network congestion, performance baselining and evaluation, file system journaling overheads, and high availability in a system with tens of thousands of components. We also discuss areas of continued challenges, such as stressed metadata performance and the need for file system quality of service alongside with our efforts to address them. Finally, operational aspects of managing a system of this scale are discussed along with real-world data and observations.

    Arctic aerosols are often attributed to the Arctic Haze and long-range transport tracers. There is, however, an important dust source in the Arctic/Sub-arctic region which should receive more attention. The largest desert in the Arctic as well as in the Europe is Iceland with > 40,000 km2 of desert areas. The mean dust suspension frequency was 135 dust days annually in 1949-2012 with decreasing numbers in 2013-2015. The annual dust deposition was calculated as 31-40 million tons yr-1 affecting the area of > 500,000 km2. Satelite MODIS pictures have revealed dust plumes traveling > 1000 km at times. The physical properties of Icelandic dust showed differences in mineralogy, geochemical compositions, shapes, sizes, and colour, compared to the crustal mineral dust. Icelandic dust is of volcanic origin, dark in colour with sharp-tipped shards and large bubbles. About 80% of the particulate matter is volcanic glass rich in heavy metals, such as iron and titanium. Suspended dust measured at the glacial dust source consisted of such high number of close-to-ultrafine particles as concentrations during active eruptions. Generally, about 50% of the suspended PM10 are submicron particles in Iceland. Contrarily, suspended grains > 2 mm were captured during severe dust storm after the 2010 Eyjafjallajokull eruption when the aeolian transport exceeded 11 t m-1 of materials and placed this storms among the most extreme wind erosion events recorded on Earth. Our reflectance measurements showed that Icelandic dust deposited on snow lowers the snow albedo and reduces the snow density as much as Black Carbon. Icelandic volcanic dust tends to act as a positive climate forcing agent, both directly and indirectly, which is different to what generally concluded for crustal dust in the 2013 IPCC report. The high frequency, severity and year-round activity of volcanic dust emissions suggest that Icelandic dust may contribute to Arctic warming.

    Background Local school districts are often one of the largest, if not the largest, employers in their respective communities. Like many large employers, school districts offer health insurance to their employees. There is a lack of information about the rate of health insurance premiums in US school districts relative to other employers. Objective To assess the change in the costs of healthcare insurance in the 5 largest public school districts in the United States, between 2004 and 2008, as representative of large public employers in the country. Methods Data for this study were drawn exclusively from a survey sent to the 5 largest public school districts in the United States. The survey requested responses on 3 data elements for each benefit plan offered from 2004 through 2008; these included enrollment, employee costs, and employer costs. Results The premium growth for the 5 largest school districts has slowed down and is consistent with other purchasers—Kaiser/Health Research & Educational Trust and the Federal Employee Health Benefit Program. The average increase in health insurance premium for the schools was 5.9% in 2008, and the average annual growth rate over the study period was 7.5%. For family coverage, these schools provide the most generous employer contribution (80.8%) compared with the employer contribution reported by other employers (73.5%) for 2008. Conclusions Often the largest employers in their communities, school districts demonstrate a commitment to provide choice of benefits and affordability for employees and their families. Despite constraints typical of public employers, the 5 largest school districts in the United States have decelerated in premium growth consistent with other purchasers, albeit at a slower pace.

  2. What caused the UK's largest common dolphin (Delphinus delphis mass stranding event?

    Directory of Open Access Journals (Sweden)

    Paul D Jepson

    Full Text Available On 9 June 2008, the UK's largest mass stranding event (MSE of short-beaked common dolphins (Delphinus delphis occurred in Falmouth Bay, Cornwall. At least 26 dolphins died, and a similar number was refloated/herded back to sea. On necropsy, all dolphins were in good nutritive status with empty stomachs and no evidence of known infectious disease or acute physical injury. Auditory tissues were grossly normal (26/26 but had microscopic haemorrhages (5/5 and mild otitis media (1/5 in the freshest cases. Five lactating adult dolphins, one immature male, and one immature female tested were free of harmful algal toxins and had low chemical pollutant levels. Pathological evidence of mud/seawater inhalation (11/26, local tide cycle, and the relative lack of renal myoglobinuria (26/26 suggested MSE onset on a rising tide between 06:30 and 08∶21 hrs (9 June. Potential causes excluded or considered highly unlikely included infectious disease, gas/fat embolism, boat strike, by-catch, predator attack, foraging unusually close to shore, chemical or algal toxin exposure, abnormal weather/climatic conditions, and high-intensity acoustic inputs from seismic airgun arrays or natural sources (e.g., earthquakes. International naval exercises did occur in close proximity to the MSE with the most intense part of the exercises (including mid-frequency sonars occurring four days before the MSE and resuming with helicopter exercises on the morning of the MSE. The MSE may therefore have been a "two-stage process" where a group of normally pelagic dolphins entered Falmouth Bay and, after 3-4 days in/around the Bay, a second acoustic/disturbance event occurred causing them to strand en masse. This spatial and temporal association with the MSE, previous associations between naval activities and cetacean MSEs, and an absence of other identifiable factors known to cause cetacean MSEs, indicates naval activity to be the most probable cause of the Falmouth Bay MSE.

    Full Text Available Dendrocalamus sinicus is the world's largest bamboo species with strong woody culms, and known for its fast-growing culms. As an economic bamboo species, it was popularized for multi-functional applications including furniture, construction, and industrial paper pulp. To comprehensively elucidate the molecular processes involved in its culm elongation, Illumina paired-end sequencing was conducted. About 65.08 million high-quality reads were produced, and assembled into 81,744 unigenes with an average length of 723 bp. A total of 64,338 (79% unigenes were annotated for their functions, of which, 56,587 were annotated in the NCBI non-redundant protein database and 35,262 were annotated in the Swiss-Prot database. Also, 42,508 and 21,009 annotated unigenes were allocated to gene ontology (GO categories and clusters of orthologous groups (COG, respectively. By searching against the Kyoto Encyclopedia of Genes and Genomes Pathway database (KEGG, 33,920 unigenes were assigned to 128 KEGG pathways. Meanwhile, 8,553 simple sequence repeats (SSRs and 81,534 single-nucleotide polymorphism (SNPs were identified, respectively. Additionally, 388 transcripts encoding lignin biosynthesis were detected, among which, 27 transcripts encoding Shikimate O-hydroxycinnamoyltransferase (HCT specifically expressed in D. sinicus when compared to other bamboo species and rice. The phylogenetic relationship between D. sinicus and other plants was analyzed, suggesting functional diversity of HCT unigenes in D. sinicus. We conjectured that HCT might lead to the high lignin content and giant culm. Given that the leaves are not yet formed and culm is covered with sheaths during culm elongation, the existence of photosynthesis of bamboo culm is usually neglected. Surprisedly, 109 transcripts encoding photosynthesis were identified, including photosystem I and II, cytochrome b6/f complex, photosynthetic electron transport and F-type ATPase, and 24 transcripts were characterized

    Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) is the world's largest social welfare scheme in India for the poverty alleviation through rural employment generation. This paper aims to evaluate and rank the performance of the states in India under MGNREGA scheme. A non-parametric approach, Data Envelopment Analysis (DEA) is used to calculate the overall technical, pure technical, and scale efficiencies of states in India. The sample data is drawn from the annual official reports published by the Ministry of Rural Development, Government of India. Based on three selected input parameters (expenditure indicators) and five output parameters (employment generation indicators), I apply both input and output oriented DEA models to estimate how well the states utilize their resources and generate outputs during the financial year 2013-14. The relative performance evaluation has been made under the assumption of constant returns and also under variable returns to scale to assess the impact of scale on performance. The results indicate that the main source of inefficiency is both technical and managerial practices adopted. 11 states are overall technically efficient and operate at the optimum scale whereas 18 states are pure technical or managerially efficient. It has been found that for some states it necessary to alter scheme size to perform at par with the best performing states. For inefficient states optimal input and output targets along with the resource savings and output gains are calculated. Analysis shows that if all inefficient states operate at optimal input and output levels, on an average 17.89% of total expenditure and a total amount of $780million could have been saved in a single year. Most of the inefficient states perform poorly when it comes to the participation of women and disadvantaged sections (SC&ST) in the scheme. In order to catch up with the performance of best performing states, inefficient states on an average need to enhance

  5. Distribution and Modeled Transport of Plastic Pollution in the Great Lakes, the World's Largest Freshwater Resource

    Full Text Available Most plastic pollution originates on land. As such, freshwater bodies serve as conduits for the transport of plastic litter to the ocean. Understanding the concentrations and fluxes of plastic litter in freshwater ecosystems is critical to our understanding of the global plastic litter budget and underpins the success of future management strategies. We conducted a replicated field survey of surface plastic concentrations in four lakes in the North American Great Lakes system, the largest contiguous freshwater system on the planet. We then modeled plastic transport to resolve spatial and temporal variability of plastic distribution in one of the Great Lakes, Lake Erie. Triplicate surface samples were collected at 38 stations in mid-summer of 2014. Plastic particles >106 μm in size were quantified. Concentrations were highest near populated urban areas and their water infrastructure. In the highest concentration trawl, nearly 2 million fragments km−2 were found in the Detroit River—dwarfing previous reports of Great Lakes plastic abundances by over 4-fold. Yet, the accuracy of single trawl counts was challenged: within-station plastic abundances varied 0- to 3-fold between replicate trawls. In the smallest size class (106–1,000 μm, false positive rates of 12–24% were determined analytically for plastic vs. non-plastic, while false negative rates averaged ~18%. Though predicted to form in summer by the existing Lake Erie circulation model, our transport model did not predict a permanent surface “Lake Erie Garbage Patch” in its central basin—a trend supported by field survey data. Rather, general eastward transport with recirculation in the major basins was predicted. Further, modeled plastic residence times were drastically influenced by plastic buoyancy. Neutrally buoyant plastics—those with the same density as the ambient water—were flushed several times slower than plastics floating at the water's surface and exceeded the

    Field trials have demonstrated the efficacy of insecticide-treated nets, and the WHO has recently endorsed a shift toward Long-Lasting Insecticide Treated nets (LLINs) due to factors such as reduced distribution costs. However, the need for LLINs poses several challenges. Is it possible to manufacture LLINs in large quantities in the African continent, where malaria is most endemic? When production is located in low-income countries, what role is played by local funding and employment, scaling up manufacturing, and partnerships? What factors influence availability and pricing? A case study of A to Z Textiles was undertaken to answer the question of how large-scale production of LLINs can occur in a low income setting. One of the largest sources of bed nets for Africa, A to Z Textiles is Africa-based, and its Tanzanian operations have a production capacity of 30 million LLINs per year, along with full WHO recommendation for its nets. Our analysis is based on semi-structured interviews with key informants familiar with A to Z, site visits in Tanzania, and literature reviews.This paper discusses the history and current status of A to Z Textiles, identifies the factors that led to its success, and suggests policy considerations that could support similar initiatives in the future. Local funding, scaling up manufacturing, technology transfer, and partnerships all played important roles in A to Z's ascent, as did perceived benefits of local employment and capacity-building. Regulatory issues and procurement rules acted as barriers. A to Z cost-effectively manufactures high-quality LLINs where malaria is most endemic. With a production capacity of 30 million LLINs per year, and full WHOPES (WHO Pesticide Evaluation Scheme) certification, A to Z Textiles demonstrates how key health goods can be successfully produced in the low-income countries that use them. Its example may be instructive and of high interest to readers in the malaria community, especially in developing

    It remains unclear whether the low incidence of gastric cancer in Indonesia is due to low infection rates only or is also related to low Helicobacter pylori pathogenicity. We collected H. pylori strains from the five largest islands in Indonesia and evaluated genetic virulence factors. The genotypes of H. pylori virulence factors were determined by polymerase chain reaction (PCR)-based sequencing. Histological severity of the gastric mucosa was classified into 4 grades, according to the updated Sydney system. A total of 44 strains were analyzed. Forty-three (97.7 %) were cagA-positive: 26 (60.5 %) were East-Asian-type-cagA, 9 (20.9 %) were Western-type-cagA, and 8 (18.6 %) were novel ABB-type, most of which were obtained from Papuan. EPIYT sequences were more prevalent than EPIYA sequences (P = 0.01) in the EPIYA-B motif of all types of cagA. The majority of cagA-positive strains (48.8 %, 21/43) had a 6-bp deletion in the first pre-EPIYA region. Subjects infected with East-Asian-type-cagA strains with a 6-bp deletion had significantly lower inflammation and atrophy scores in the corpus than those infected with Western-type-cagA strains (both P = 0.02). In total, 70.4 % of strains possessed the vacA s1m1 genotype and 29.5 % were m2. All strains from peptic ulcer patients were of the iceA1 genotype, which occurred at a significantly higher proportion in peptic ulcer patients than that in gastritis patients (55.3 %, P = 0.04). The double positive genotype of jhp0562/β-(1,3)galT was predominant (28/44, 63.6 %), and subjects infected with this type had significantly higher inflammation scores in the corpus than those with the jhp0562 negative/β-(1,3)galT positive genotype (mean [median]; 1.43 [1] vs. 0.83 [1], P = 0.04). There were significant differences in cagA and pre-EPIYA cagA type, oipA status, and jhp0562/β-(1,3)galT type among different ethnic groups (P dupA negative or short type dupA, and the jhp0562/β-(1,3)galT double positive genotype.

    On 9 June 2008, the UK's largest mass stranding event (MSE) of short-beaked common dolphins (Delphinus delphis) occurred in Falmouth Bay, Cornwall. At least 26 dolphins died, and a similar number was refloated/herded back to sea. On necropsy, all dolphins were in good nutritive status with empty stomachs and no evidence of known infectious disease or acute physical injury. Auditory tissues were grossly normal (26/26) but had microscopic haemorrhages (5/5) and mild otitis media (1/5) in the freshest cases. Five lactating adult dolphins, one immature male, and one immature female tested were free of harmful algal toxins and had low chemical pollutant levels. Pathological evidence of mud/seawater inhalation (11/26), local tide cycle, and the relative lack of renal myoglobinuria (26/26) suggested MSE onset on a rising tide between 06∶30 and 08∶21 hrs (9 June). Potential causes excluded or considered highly unlikely included infectious disease, gas/fat embolism, boat strike, by-catch, predator attack, foraging unusually close to shore, chemical or algal toxin exposure, abnormal weather/climatic conditions, and high-intensity acoustic inputs from seismic airgun arrays or natural sources (e.g., earthquakes). International naval exercises did occur in close proximity to the MSE with the most intense part of the exercises (including mid-frequency sonars) occurring four days before the MSE and resuming with helicopter exercises on the morning of the MSE. The MSE may therefore have been a “two-stage process” where a group of normally pelagic dolphins entered Falmouth Bay and, after 3–4 days in/around the Bay, a second acoustic/disturbance event occurred causing them to strand en masse. This spatial and temporal association with the MSE, previous associations between naval activities and cetacean MSEs, and an absence of other identifiable factors known to cause cetacean MSEs, indicates naval activity to be the most probable cause of the Falmouth Bay MSE.

    Dendrocalamus sinicus is the world's largest bamboo species with strong woody culms, and known for its fast-growing culms. As an economic bamboo species, it was popularized for multi-functional applications including furniture, construction, and industrial paper pulp. To comprehensively elucidate the molecular processes involved in its culm elongation, Illumina paired-end sequencing was conducted. About 65.08 million high-quality reads were produced, and assembled into 81,744 unigenes with an average length of 723 bp. A total of 64,338 (79%) unigenes were annotated for their functions, of which, 56,587 were annotated in the NCBI non-redundant protein database and 35,262 were annotated in the Swiss-Prot database. Also, 42,508 and 21,009 annotated unigenes were allocated to gene ontology (GO) categories and clusters of orthologous groups (COG), respectively. By searching against the Kyoto Encyclopedia of Genes and Genomes Pathway database (KEGG), 33,920 unigenes were assigned to 128 KEGG pathways. Meanwhile, 8,553 simple sequence repeats (SSRs) and 81,534 single-nucleotide polymorphism (SNPs) were identified, respectively. Additionally, 388 transcripts encoding lignin biosynthesis were detected, among which, 27 transcripts encoding Shikimate O-hydroxycinnamoyltransferase (HCT) specifically expressed in D. sinicus when compared to other bamboo species and rice. The phylogenetic relationship between D. sinicus and other plants was analyzed, suggesting functional diversity of HCT unigenes in D. sinicus. We conjectured that HCT might lead to the high lignin content and giant culm. Given that the leaves are not yet formed and culm is covered with sheaths during culm elongation, the existence of photosynthesis of bamboo culm is usually neglected. Surprisedly, 109 transcripts encoding photosynthesis were identified, including photosystem I and II, cytochrome b6/f complex, photosynthetic electron transport and F-type ATPase, and 24 transcripts were characterized as antenna

    Full Text Available Abstract Background Field trials have demonstrated the efficacy of insecticide-treated nets, and the WHO has recently endorsed a shift toward Long-Lasting Insecticide Treated nets (LLINs due to factors such as reduced distribution costs. However, the need for LLINs poses several challenges. Is it possible to manufacture LLINs in large quantities in the African continent, where malaria is most endemic? When production is located in low-income countries, what role is played by local funding and employment, scaling up manufacturing, and partnerships? What factors influence availability and pricing? Discussion A case study of A to Z Textiles was undertaken to answer the question of how large-scale production of LLINs can occur in a low income setting. One of the largest sources of bed nets for Africa, A to Z Textiles is Africa-based, and its Tanzanian operations have a production capacity of 30 million LLINs per year, along with full WHO recommendation for its nets. Our analysis is based on semi-structured interviews with key informants familiar with A to Z, site visits in Tanzania, and literature reviews. This paper discusses the history and current status of A to Z Textiles, identifies the factors that led to its success, and suggests policy considerations that could support similar initiatives in the future. Local funding, scaling up manufacturing, technology transfer, and partnerships all played important roles in A to Z’s ascent, as did perceived benefits of local employment and capacity-building. Regulatory issues and procurement rules acted as barriers. A to Z cost-effectively manufactures high-quality LLINs where malaria is most endemic. Summary With a production capacity of 30 million LLINs per year, and full WHOPES (WHO Pesticide Evaluation Scheme certification, A to Z Textiles demonstrates how key health goods can be successfully produced in the low-income countries that use them. Its example may be instructive and of high interest to

    The largest epidemic of avian influenza (AI) in history attacked poultry and wild birds throughout Taiwan starting January 6, 2015. This study analyzed surveillance results, epidemiologic characteristics, and viral sequences by using government-released information, with the intention to provide recommendations to minimize future pandemic influenza. The H5 clade 2.3.4.4 highly pathogenic AI viruses (HPAIVs) had not been detected in Taiwan before 2015. During this epidemic, four types of etiologic agents were identified: the three novel subtypes H5N2, H5N8, and H5N3 clade 2.3.4.4 HPAIVs and one endemic chicken H5N2 subtype (Mexican-like lineage) of low pathogenic AI viruses. Cocirculation of mixed subtypes also occurred, with H5N2 clade 2.3.4.4 HPAIVs accompanied by the H5N8 and H5N3 subtypes or old H5N2 viruses in the same farm. More than 90% of domestic geese died from this AI epidemic; geese were affected the most at the early outbreaks. The epidemic peaked in mid-January for all three novel H5 subtypes. Spatial epidemiology found that most affected areas were located in southwestern coastal areas. In terrestrial poultry (mostly chickens), different geographic distributions of AI virus subtypes were detected, with hot spots of H5N2 clade 2.3.4.4 vs. past-endemic old H5N2 viruses in Changhwa (P = 0.03) and Yunlin (P = 0.007) counties, respectively, of central Taiwan. Phylogenetic and sequence analyses of all the early 10 Taiwan H5 clade 2.3.4.4 isolates covering the three subtypes showed that they were very different from the HA of the past local H5 viruses from domestic ducks (75%-80%) and chickens (70%-75%). However, they had the highest sequence identity percentages (99.53%-100%), with the HA of A/crane/Kagoshima/KU13/2014(H5N8) isolated on December 7, 2014, in Japan being higher than those of recent American and Korean H5 HPAIVs [A/Northern pintail/Washington/40964/2014 (H5N2) and A/gyrfalcon/Washington/41088-6/2014 (H5N8): 99.02%-99.54% and A/Baikal teal

  13. Astronomers Break Ground on Atacama Large Millimeter Array (ALMA) - World's Largest Millimeter Wavelength Telescope

    2003-11-01

    Scientists and dignitaries from Europe, North America and Chile are breaking ground today (Thursday, November 6, 2003) on what will be the world's largest, most sensitive radio telescope operating at millimeter wavelengths . ALMA - the "Atacama Large Millimeter Array" - will be a single instrument composed of 64 high-precision antennas located in the II Region of Chile, in the District of San Pedro de Atacama, at the Chajnantor altiplano, 5,000 metres above sea level. ALMA 's primary function will be to observe and image with unprecedented clarity the enigmatic cold regions of the Universe, which are optically dark, yet shine brightly in the millimetre portion of the electromagnetic spectrum. The Atacama Large Millimeter Array (ALMA) is an international astronomy facility. ALMA is an equal partnership between Europe and North America, in cooperation with the Republic of Chile, and is funded in North America by the U.S. National Science Foundation (NSF) in cooperation with the National Research Council of Canada (NRC), and in Europe by the European Southern Observatory (ESO) and Spain. ALMA construction and operations are led on behalf of North America by the National Radio Astronomy Observatory (NRAO), which is managed by Associated Universities, Inc. (AUI), and on behalf of Europe by ESO. " ALMA will be a giant leap forward for our studies of this relatively little explored spectral window towards the Universe" , said Dr. Catherine Cesarsky , Director General of ESO. "With ESO leading the European part of this ambitious and forward-looking project, the impact of ALMA will be felt in wide circles on our continent. Together with our partners in North America and Chile, we are all looking forward to the truly outstanding opportunities that will be offered by ALMA , also to young scientists and engineers" .

  14. ESO Signs Largest-Ever European Industrial Contract For Ground-Based Astronomy Project ALMA

    Science.gov (United States)

    2005-12-01

    ESO, the European Organisation for Astronomical Research in the Southern Hemisphere, announced today that it has signed a contract with the consortium led by Alcatel Alenia Space and composed also of European Industrial Engineering (Italy) and MT Aerospace (Germany), to supply 25 antennas for the Atacama Large Millimeter Array (ALMA) project, along with an option for another seven antennas. The contract, worth 147 million euros, covers the design, manufacture, transport and on-site integration of the antennas. It is the largest contract ever signed in ground-based astronomy in Europe. The ALMA antennas present difficult technical challenges, since the antenna surface accuracy must be within 25 microns, the pointing accuracy within 0.6 arc seconds, and the antennas must be able to be moved between various stations on the ALMA site. This is especially remarkable since the antennas will be located outdoor in all weather conditions, without any protection. Moreover, the ALMA antennas can be pointed directly at the Sun. ALMA will have a collecting area of more than 5,600 square meters, allowing for unprecedented measurements of extremely faint objects. The signing ceremony took place on December 6, 2005 at ESO Headquarters in Garching, Germany. "This contract represents a major milestone. It allows us to move forward, together with our American and Japanese colleagues, in this very ambitious and unique project," said ESO's Director General, Dr. Catherine Cesarsky. "By building ALMA, we are giving European astronomers access to the world's leading submillimetre facility at the beginning of the next decade, thereby fulfilling Europe's desire to play a major role in this field of fundamental research." Pascale Sourisse, Chairman and CEO of Alcatel Alenia Space, said: "We would like to thank ESO for trusting us to take on this new challenge. We are bringing to the table not only our recognized expertise in antenna development, but also our long-standing experience in

    Full Text Available The deep sea, the largest biome on Earth, has a series of characteristics that make this environment both distinct from other marine and land ecosystems and unique for the entire planet. This review describes these patterns and processes, from geological settings to biological processes, biodiversity and biogeographical patterns. It concludes with a brief discussion of current threats from anthropogenic activities to deep-sea habitats and their fauna.

    Investigations of deep-sea habitats and their fauna began in the late 19th century. In the intervening years, technological developments and stimulating discoveries have promoted deep-sea research and changed our way of understanding life on the planet. Nevertheless, the deep sea is still mostly unknown and current discovery rates of both habitats and species remain high. The geological, physical and geochemical settings of the deep-sea floor and the water column form a series of different habitats with unique characteristics that support specific faunal communities. Since 1840, 28 new habitats/ecosystems have been discovered from the shelf break to the deep trenches and discoveries of new habitats are still happening in the early 21st century. However, for most of these habitats the global area covered is unknown or has been only very roughly estimated; an even smaller – indeed, minimal – proportion has actually been sampled and investigated. We currently perceive most of the deep-sea ecosystems as heterotrophic, depending ultimately on the flux on organic matter produced in the overlying surface ocean through photosynthesis. The resulting strong food limitation thus shapes deep-sea biota and communities, with exceptions only in reducing ecosystems such as inter alia hydrothermal vents or cold seeps. Here, chemoautolithotrophic bacteria play the role of primary producers fuelled by chemical energy sources rather than sunlight. Other ecosystems, such as seamounts, canyons or cold

  16. Business Subsidies in Canada Comprehensive Estimates for the Government of Canada and the Four Largest Provinces

    Full Text Available Business subsidies in Canada: the “winner” is Alberta; the loser is the taxpayer The federal government and the four largest provinces in Canada spend about $29 billion a year on business subsidies, delivered through program spending, the tax system, government business enterprises and direct investments by government. These subsidies represent almost half of the corporate income tax revenue collected by the five jurisdictions. Surprisingly, given its reputation as a bastion of free enterprise, Alberta is the most prolific subsidizer. In the 2014-15 fiscal year, per person subsidies were $640 in Alberta, about $100 ahead of the next most generous jurisdiction, Québec. Alberta has probably added to its “lead” through measures introduced in the October 2015 Fiscal Update and the 2016 budget. Alberta also stands out by having the least transparent public reporting of business subsidies. What motivates governments to subsidize business? Abstracting from cynical efforts to win votes, business subsidies have two broad objectives: to improve economic performance and to achieve a social objective by supporting specific firms, industries or regions. On average in the five jurisdictions, the split between the two categories is about 70-30 in favour of economic development measures. Assessing value for money from programs with a social objective is subjective, but measures intended to improve economic performance should be assessed on their ability to raise real income. Business subsidies can only raise real income if markets fail to allocate labour and capital to their best uses. The classic case is R&D. When a firm undertakes R&D, some of the knowledge created inevitably spills over to the benefit other firms. Firms are focused on their own benefits and costs when deciding how much to spend on R&D, not the benefits received by other firms, so society has an interest in encouraging additional R&D. While markets generally do a good job allocating

    Full Text Available Studying plant species richness and composition of a wetland is essential when estimating its ecological importance and ecosystem services, especially if a particular wetland is subjected to human disturbances. Poyang Lake, located in the middle reaches of Yangtze River (central China, constitutes the largest freshwater lake of the country. It harbours high biodiversity and provides important habitat for local wildlife. A dam that will maintain the water capacity in Poyang Lake is currently being planned. However, the local biodiversity and the likely effects of this dam on the biodiversity (especially on the endemic and rare plants have not been thoroughly examined. Therefore, in order to assess the richness of plant species and plant communities in Poyang Lake, we conducted a detailed field investigation combined with a literature review. A total of 124 families, 339 genera, and 512 species (including sub-species, varieties and forms as well as eight dominant plant communities were identified, confirming the lake’s wetland as a regional hotspot of plant diversity. It is imperative to carry out further research on the impact of damming on the vegetation, particularly research focusing on protecting local biodiversity, maintaining the lake’s ecosystem services, controlling the spread of invasive species, and restoring degraded ecosystems.El estudio de la riqueza y la composición de especies vegetales de un humedal es esencial a la hora de estimar su importancia ecológica y sus servicios ecosistémicos, especialmente cuando éste está sujeto a perturbaciones humanas.

    2011-01-01

    This study examined the ownership, financing, and management strategies of the 10 largest for-profit nursing home chains in the United States, including the four largest chains purchased by private equity corporations. Descriptive data were collected from Internet searches, company reports, and other sources for the decade 1998-2008. Since 1998, the largest chains have made many changes in their ownership and structure, and some have converted from publicly traded companies to private ownership. This study shows the increasing complexity of corporate nursing home ownership and the lack of public information about ownership and financial status. The chains have used strategies to maximize shareholder and investor value that include increasing Medicare revenues, occupancy rates, and company diversification, establishing multiple layers of corporate ownership, developing real estate investment trusts, and creating limited liability companies. These strategies enhance shareholder and investor profits, reduce corporate taxes, and reduce liability risk. There is a need for greater transparency in ownership and financial reporting and for more government oversight of the largest for-profit chains, including those owned by private equity companies.

    Portugal is a European country with highest forest fires density and burned area. Since beginning of official forest fires database in 1980, an increase in number of fires and burned area as well as appearance of large and catastrophic fires have characterized fire activity in Portugal. In 1980s, the largest fires were just a little bit over 10,000 ha. However, in the beginning of 21st century several fires occurred with a burned area over 20,000 ha. Some of these events can be classified as mega-fires due to their ecological and socioeconomic severity. The present study aimed to discuss the characterization of large forest fires trend, in order to understand if the largest fires that occurred in Portugal were exceptional events or evidences of a new trend, and the constraints of fire size to characterize fire effects because, usually, it is assumed that larger the fire higher the damages. Using Portuguese forest fire database and satellite imagery, the present study showed that the largest fires could be seen at the same time as exceptional events and as evidence of a new fire regime. It highlighted the importance of size and patterns of unburned patches within fire perimeter as well as heterogeneity of fire ecological severity, usually not included in fire regime description, which are critical to fire management and research. The findings of this research can be used in forest risk reduction and suppression planning.

    When Thornes and Brunsden wrote in 1977 "How often one hears the researcher (and no less the undergraduate) complain that after weeks of observation "nothing happened" only to learn that, the day after his departure, a flood caused unprecedent erosion and channel changes!" (Thornes and Brunsden, 1977, p. 57), they focussed on two different problems in geomorphological research: the effects of extreme events and the temporal compression of geomorphological processes. The time compression is one of the main characteristic of erosion processes. It means that an important amount of the total soil eroded is produced in very short temporal intervals, i.e. few events mostly related to extreme events. From magnitude-frequency analysis we know that few events, not necessarily extreme by magnitude, produce high amount of geomorphological work. Last but not least, extreme isolated events are a classical issue in geomorphology by their specific effects, and they are receiving permanent attention, increased at present because of scenarios of global change. Notwithstanding, the time compression of geomorphological processes could be focused not only on the analysis of extreme events and the traditional magnitude-frequency approach, but on new complementary approach based on the effects of largest events. The classical approach define extreme event as a rare event (identified by its magnitude and quantified by some deviation from central value), while we define largest events by the rank, whatever their magnitude. In a previous research on time compression of soil erosion, using USLE soil erosion database (Gonzalez-Hidalgo et al., EGU 2007), we described a relationship between the total amount of daily erosive events recorded by plot and the percentage contribution to total soil erosion of n-largest aggregated daily events. Now we offer a further refined analysis comparing different agricultural regions in USA. To do that we have analyzed data from 594 erosion plots from USLE

    The emergence of the Internet has made it easier for people to socially interact than ever before. Today, the most popular channel is Facebook with over 845 million users world wide. In Sweden, the number of users amount to approximately half of the population. We had two aims with this study. First, we investigate which areas of Facebook usage that Swedish Facebook users consider more important vis-a-vis less important. We were also interested in how users convey their persona through t... m...

    Mitsubishi Electric has delivered the world's largest DC generator for the toroidal field coil power supply of the JFT-2M Tokamak at the Japan Atomic Energy Research Institute. The unit rotates at 225 or 460 rpm, providing a maximum rated output of 2,700 V, 19,000 A and 51.3 MW. The toroidal field is a DC field, so use of a DC generator permits a simpler design consuming less floor space than an AC drive system. The generator was manufactured following extensive studies on commutation, mechanical strength and insulation. (author)

    2010-01-01

    Studies of peer-to-peer lending in the USA find that female borrowers have better chances of getting funds than males. Is differential treatment of borrowers of different sexes a common feature of peer-to-peer lendingmarkets or is it subject to specific businessmodels, ways of fixing loan contracts and even national financial systems? We aim at answering this question by providing evidence on loan procurement at the largest German peer-to-peer lending platform Smava.de. Our results show that ...

    Large fluctuations in quantities such as density are characteristic of critical phenomena in the neighborhood of the critical point. Using the EOS apparatus at the Bevalac, we have performed an exclusive experiment in which the size of the largest projectile fragment produced in 1 GeV/nucleon Au+C collisions is studied as a function of the charged multiplicity of the event. A peak in the fluctuations is expected at the critical multiplicity. The data are compared to a percolation model and a statistical multifragmentation model

    China becomes the largest emitter along with the United States. Contents: 1990-2007 evolution (key figures of Yearly average evolutions); Global CO_2-energy emissions in 2007: 27,3 GtCO_2; Global CO_2-energy emissions have increased by 3,2% in 2007, largely driven by China. Since 1990, China has more than doubled its CO_2-energy emissions, to reach the same emission level as the USA in 2007. Two very contrasting tendencies appear since 1990: stabilization of emissions in Annex B countries, boom in China and India. Since 1990, more than half of CO_2-energy emissions growth is (logically) due to coal. (authors)

  17. Distribution of the largest aftershocks in branching models of triggered seismicity: Theory of the universal Baath law

    International Nuclear Information System (INIS)

    Saichev, A.; Sornette, D.

    2005-01-01

    Using the epidemic-type aftershock sequence (ETAS) branching model of triggered seismicity, we apply the formalism of generating probability functions to calculate exactly the average difference between the magnitude of a mainshock and the magnitude of its largest aftershock over all generations. This average magnitude difference is found empirically to be independent of the mainshock magnitude and equal to 1.2, a universal behavior known as Baath's law. Our theory shows that Baath's law holds only sufficiently close to the critical regime of the ETAS branching process. Allowing for error bars ±0.1 for Baath's constant value around 1.2, our exact analytical treatment of Baath's law provides new constraints on the productivity exponent α and the branching ratio n: 0.9 < or approx. α≤1 and 0.8 < or approx. n≤1. We propose a method for measuring α based on the predicted renormalization of the Gutenberg-Richter distribution of the magnitudes of the largest aftershock. We also introduce the 'second Baath law for foreshocks': the probability that a main earthquake turns out to be the foreshock does not depend on its magnitude ρ

    Full Text Available DOI: http://dx.doi.org/10.5007/2175-8077.2012v14n32p65 The aim of this article is to introduce the practices of leadership in the largest industries of Santa Catarina and their contribution to the Knowledge Management. The organization competitiveness is related to the people and to the capacity of the companies to improve the constant development of knowledge. Using the leadership, the managers and the People Management have created compromise and improved the results of the organizations. The adopted methodology followed the qualitative methodology, descriptive and applied research. There were interviewed the seven largest industries of the state of Santa Catarina, in number of collaborators. The data were analyzed by the technique of analysis of content. It has been observed that the leadership is present in the most of the studied companies, by the use of formal programs of development of leaders or of actions related to leadership. It is concluded that the companies have the focus in the people and in the knowledge, in bigger or smaller degree, but some of them are in phase of transition and revision of programs towards the development of their talents and of the Knowledge Management.

    Highlights: ► The maximal predictive step size is determined by the largest Lyapunov exponent. ► A proper forecasting step size is applied to load demand forecasting. ► The improved approach is validated by the actual load demand data. ► Non-linear fractal extrapolation method is compared with three forecasting models. ► Performance of the models is evaluated by three different error measures. - Abstract: Precise short-term load forecasting (STLF) plays a key role in unit commitment, maintenance and economic dispatch problems. Employing a subjective and arbitrary predictive step size is one of the most important factors causing the low forecasting accuracy. To solve this problem, the largest Lyapunov exponent is adopted to estimate the maximal predictive step size so that the step size in the forecasting is no more than this maximal one. In addition, in this paper a seldom used forecasting model, which is based on the non-linear fractal extrapolation (NLFE) algorithm, is considered to develop the accuracy of predictions. The suitability and superiority of the two solutions are illustrated through an application to real load forecasting using New South Wales electricity load data from the Australian National Electricity Market. Meanwhile, three forecasting models: the gray model, the seasonal autoregressive integrated moving average approach and the support vector machine method, which received high approval in STLF, are selected to compare with the NLFE algorithm. Comparison results also show that the NLFE model is outstanding, effective, practical and feasible.

    Full Text Available Scenario urbano principale dei due romanzi Madre piccola (2007 e Il comandante del fiume (2014, la città di Roma viene ricostruita narrativamente dalla scrittrice italo-somala Cristina Ali Farah secondo prospettive e tensioni nuove e significative. Le geografie degli spazi esterni ed interni della città rispondono in entrambi i testi a delle dinamiche identitarie le quali sono attraversate da temi comuni agli scrittori contemporanei della diaspora africana: la dialettica tra presenza ed assenza (di persone, di luoghi, la precarietà e l’instabilità della dimora d’arrivo, il conflitto tra la memoria traumatica e la necessità di radicarsi nell’hic et nunc spaziale ed esistenziale, la rilettura degli spazi urbani in chiave postcoloniale. A partire da tale matrice tematica, la narrativa di Ali Farah si carica di simbologie e di metafore nuove, che rimandano alla sua poetica e al suo immaginario ben personali. Subentra, nella lettura critica dei testi in questione, anche la considerazione dell’aspetto generazionale, che contrassegna i personaggi, e del diverso vivere la città d’approdo nel caso di biografie finzionali segnate dalla fuga e dalla diaspora, o viceversa dai legami con essa degli esponenti delle “seconde generazioni”.   The city of Rome is the main urban scenario of Cristina Ali Farah's two novels Madre piccola (2007 and Il comandante del fiume (2014, being constructed narratively from new perspectives and using significant narrative strategies.

    Bioaerosol concentration was measured in wastewater treatment units in south of Tehran, the largest wastewater treatment plant in the Middle East. Active sampling was carried out around four operational units and a point as background. The results showed that the aeration tank with an average of 1016 CFU/m(3) in winter and 1973 CFU/m(3) in summer had the greatest effect on emission of bacterial bioaerosols. In addition, primary treatment had the highest impact on fungal emission. Among the bacteria, Micrococcus spp. showed the widest emission in the winter, and Bacillus spp. was dominant in summer. Furthermore, fungi such as Penicillium spp. and Cladosporium spp. were the dominant types in the seasons. Overall, significant relationship was observed between meteorological parameters and the concentration of bacterial and fungal aerosols.

  2. Spatial Air Index Based on Largest Empty Rectangles for Non-Flat Wireless Broadcast in Pervasive Computing

    2016-11-01

    Full Text Available In pervasive computing, location-based services (LBSs are valuable for mobile clients based on their current locations. LBSs use spatial window queries to enable useful applications for mobile clients. Based on skewed access patterns of mobile clients, non-flat wireless broadcast has been shown to efficiently disseminate spatial objects to mobile clients. In this paper, we consider a scenario in which spatial objects are broadcast to mobile clients over a wireless channel in a non-flat broadcast manner to process window queries. For such a scenario, we propose an efficient spatial air index method to handle window query access in non-flat wireless broadcast environments. The concept of largest empty rectangles is used to avoid unnecessary examination of the broadcast content, thus reducing the processing time for window queries. Simulation results show that the proposed spatial air index method outperforms the existing methods under various settings.

    Full Text Available In 1996, a Canadian company started geological explorations in the Rosia Montana area in the Romanian Carpathians. Two years later it formed a joint-venture with a Romanian state company to exploit what is believed to be Europe´s largest gold reserves. However, as of June 2011 extraction has not started yet and it may never start due to the opposition of numerous NGO´s that have pointed out the environmental, social and economic unsustainability of this mining project. This situation is highly unusual for a country that is hungry for foreign investment especially since up until very recently the state had supported any project promising to revitalize its mining sector. This paper will investigate the changes in the discourses surrounding this mining project taking into consideration the effects of globalization and the effects of Romania´s EU membership after 2007.

    The paper examines causes and effects of ownership concentration among the largest companies in 12 European countries. As a reference point the paper takes a seminal empirical study on US data by Demsetz and Lehn (1985) and examines to what extent their model is applicable in European countries....... The findings indicate that both general economic effects and system effects are significant. Ownership concentration is found to decrease with firm size and to increase with earnings volatility. But in support of the system theories advocated by Roe (1991), Laporta et al. (1996) and Shleifer and Vishny (1997......) nationality is also found to have a significant effect which is partly attributable to institutional differences between nations such as stock market size and the frequency of large banks. Finally, in line with Demsetz and Lehn (1985), ownership concentration is found to have an insignificant effect...

    The whale shark (Rhincodon typus) has by far the largest body size of any elasmobranch (shark or ray) species. Therefore, it is also the largest extant species of the paraphyletic assemblage commonly referred to as fishes. As both a phenotypic extreme and a member of the group Chondrichthyes - the sister group to the remaining gnathostomes, which includes all tetrapods and therefore also humans - its genome is of substantial comparative interest. Whale sharks are also listed as an endangered species on the International Union for Conservation of Nature's Red List of threatened species and are of growing popularity as both a target of ecotourism and as a charismatic conservation ambassador for the pelagic ecosystem. A genome map for this species would aid in defining effective conservation units and understanding global population structure. We characterised the nuclear genome of the whale shark using next generation sequencing (454, Illumina) and de novo assembly and annotation methods, based on material collected from the Georgia Aquarium. The data set consisted of 878,654,233 reads, which yielded a draft assembly of 1,213,200 contigs and 997,976 scaffolds. The estimated genome size was 3.44Gb. As expected, the proteome of the whale shark was most closely related to the only other complete genome of a cartilaginous fish, the holocephalan elephant shark. The whale shark contained a novel Toll-like-receptor (TLR) protein with sequence similarity to both the TLR4 and TLR13 proteins of mammals and TLR21 of teleosts. The data are publicly available on GenBank, FigShare, and from the NCBI Short Read Archive under accession number SRP044374. This represents the first shotgun elasmobranch genome and will aid studies of molecular systematics, biogeography, genetic differentiation, and conservation genetics in this and other shark species, as well as providing comparative data for studies of evolutionary biology and immunology across the jawed vertebrate lineages.

  7. One last boom : Alberta's rapidly expanding oil mines may be the largest and messiest industrial projects in Canadian history

    2001-01-01

    The bitumen deposits of Alberta, 2.5 trillion barrels of oil, of which 300 billion are considered recoverable, represent the greatest single petroleum resources of the world, based on surface and subsurface calculations. Four deposits, covering an area the size of New Brunswick, are located in the area stretching from Cold Lake to Lloydminster (east of Edmonton), the upper reaches of the Athabasca River east to the Peace River. The largest by far is the Athabasca deposit in the vicinity of Fort McMurray, spread over 4.3 million hectares. The deposit is at the centre of the biggest industrial expansion witnessed by the province. Since 1996, 38 billion dollars worth of new projects have been announced. It is estimated that by 2025, the bulk of the national oil production will originate from open-pit mines and underground wells around Fort McMurray. This oil boom has economic benefits for the population, from welders to real estate agents to stakeholders. The environmental effects are not as beneficial. Huge strip mines are being carved next to the Athabasca River, with great amounts of greenhouse gases emissions. The Suncor and Syncrude oil-sands plants combined represent the fourth largest carbon dioxide emission source in Canada. The development of these projects dramatically affects global warming. The nitrogen and sulphur emissions could also acidify lakes and soil in the region. The Suncor mine resulted from the first boom to hit Fort McMurray in 1964. The Syncrude mine is the result of the second boom which took place in 1973. In 1996, Suncor installed a sulphur scrubber system that removes 95 per cent of sulphur dioxide from the electricity and steam-generation plant. Suncor also invested in various projects, such as wind-power, rainforest cultivation and biomass generation. The volume of pollution increases as the operations expand, even if operations are cleaner. If no new gains in pollution control are achieved, it is expected that by 2015, the total

    The use of water wasted in hydroelectric plants as normalization dam excess, which constitute a hydrodynamic potential useful to generate electric energy which can be subsequently used to produce hydrogen and its subsequent consumption in fuel cells has been considered as an alternative for hydraulic energy-rich countries like Brazil. The case is examined in which all the water wasted in the hydroelectric plants, spilled by dam gates to maintain acceptable water levels, from the 3 largest Brazilian hydroelectric plants was used to produce hydrogen. During the year of 2008, the electric energy produced from this utilization would have been equivalent to 52.8 TWh, an amount that corresponds to an increase of ca. 15% of the total electric energy produced in the country. Furthermore, if this amount of hydrogen was used in the replacement of internal combustion vehicles by fuel cells, this would have prevented the production of 2.26 x 10{sup 7} ton of Co{sub 2} per year. This plan would also significantly decrease production and release of greenhouse gases. (author)

    2014-01-01

    Full Text Available Lake Poyang is the largest freshwater lake in China and contains unique and diverse biota within the Yangtze floodplain ecosystem. However, knowledge of its macrozoobenthic assemblages remains inadequate. To characterize the current community structure of these assemblages and to portray their decadal changes, quarterly investigations were conducted at 15 sites from February to November 2012. A total of 42 taxa were recorded, and Corbicula fluminea, Limnoperna fortunei, Gammaridae sp., Nephtys polybranchia, Polypedilum scalaenum and Branchiura sowerbyi were found to dominate the community in terms of abundance. The bivalves Corbicula fluminea, Lamprotula rochechouarti, Arconaia lanceolata and Lamprotula caveata dominated the community in biomass due to their large body size. The mean abundance of the total macrozoobenthos varied from 48 to 920 ind·m-2, the mean biomass ranged from 28 to 428 g·m-2. The substrate type affected strongly the abundance, biomass, and diversity of the macrozoobenthos, with muddy sand substrates showing the highest values. Compared with historical data, remarkable changes were observed in the abundance of macrozoobenthos and the identity of the dominant species. The mean total abundance decreased from 724 ind·m-2 in 1992 to 228 ind·m-2 in 2012. The dominant species have shifted dramatically. Large unionids were dominant before 1998, whereas pollution-tolerant species (e.g., Branchiura sowerbyi increased in dominance after 2008. Our findings should have implications for the conservation of the benthic biodiversity of this large Yangtze-connected lake.

    2006-01-01

    The space-time epidemic-type aftershock sequence model is a stochastic branching process in which earthquake activity is classified into background and clustering components and each earthquake triggers other earthquakes independently according to certain rules. This paper gives the probability distributions associated with the largest event in a cluster and their properties for all three cases when the process is subcritical, critical, and supercritical. One of the direct uses of these probability distributions is to evaluate the probability of an earthquake to be a foreshock, and magnitude distributions of foreshocks and nonforeshock earthquakes. To verify these theoretical results, the Japan Meteorological Agency earthquake catalog is analyzed. The proportion of events that have 1 or more larger descendants in total events is found to be as high as about 15%. When the differences between background events and triggered event in the behavior of triggering children are considered, a background event has a probability about 8% to be a foreshock. This probability decreases when the magnitude of the background event increases. These results, obtained from a complicated clustering model, where the characteristics of background events and triggered events are different, are consistent with the results obtained in [Ogata et al., Geophys. J. Int. 127, 17 (1996)] by using the conventional single-linked cluster declustering method

    India's largest 3.6 m aperture optical telescope facility has been recently established at Devasthal site by Aryabhatta Research Institute of Observation Sciences (ARIES), an autonomous Institute under Department of Science and Technology, Government of India. The telescope is equipped with active optics and it is designed to be used for seeinglimited observations at visible and near-infrared wavelengths. A steel building with rotating cylindrical steel Dome was erected to house 3.6m telescope and its accessories at hilltop of Devasthal site. Customized cranes were essentially required inside the building as there were space constraints around the telescope building for operating big external heavy duty cranes from outside, transportation constraints in route for bringing heavy weight cranes, altitude of observatory, and sharp bends etc. to site. To meet the challenge of telescope installation from inside the telescope building by lifting components through its hatch, two Single Girder cranes and two Under Slung cranes of 10 MT capacity each were specifically designed and developed. All the four overhead cranes were custom built to achieve the goal of handling telescope mirror and its various components during installation and assembly. Overhead cranes were installed in limited available space inside the building and tested as per IS 3177. Cranes were equipped with many features like VVVFD compatibility, provision for tandem operation, digital load display, anti-collision mechanism, electrical interlocks, radio remote, low hook height and compact carriage etc. for telescope integration at site.

    Jéssica Carolinne Damasceno

    Full Text Available ABSTRACT Purpose: Malignant lesions of the eyelid are the most common eye cancers. Although rarely lethal, late diagnosis can lead to serious visual morbidity. Definitive diagnosis of neoplastic lesions is pathological. Indications and types of eyelid lesions in a single high-volume ophthalmic reference center in Sao Paulo, Brazil, were analyzed. Methods: The surgical pathological reports of patients who underwent eye removal procedures between January 2000 and December 2012 were retrieved from the electronic database of the Ophthalmology Department and retrospectively reviewed. Data regarding the final anatomopathological diagnosis, sex, and age were analyzed via the χ2 test with Yates' correction. Results: Of the 1,113 eyelid tumors resected over the 13-year study period, 324 (29% lesions were malignant. The most prevalent lesions were basal cell, squamous cell, and sebaceous gland carcinomas. The median ages of patients (females, n=165, 51%; males, n=159, 49% with a diagnosis of basal cell, squamous cell, and sebaceous gland carcinomas were 65, 75, and 70 years, respectively. Conclusion: This is the largest retrospective cohort analysis of eyelid tumors in a Latin American population. These findings are in agreement with those from large centers in other countries and regions.

    Riverine dissolved sulfate (SO4(2-)) flux and sulfur stable isotope composition (δ(34)S) yield information on the sources and processes affecting sulfur cycling on different spatial and temporal scales. However, because pristine preindustrial natural baselines of riverine SO4(2-) flux and δ(34)S cannot be directly measured, anthropogenic impact remains largely unconstrained. Here we quantify natural and anthropogenic SO4(2-) flux and δ(34)S for North America's largest river, the Mississippi, by means of an exhaustive source compilation and multiyear monitoring. Our data and analysis show that, since before industrialization to the present, Mississippi River SO4(2-) has increased in flux from 7.0 to 27.8 Tg SO4(2-) yr(-1), and in mean δ(34)S from -5.0‰, within 95% confidence limits of -14.8‰ to 4.1‰ (assuming normal distribution for mixing model input parameters), to -2.7 ± 1.6‰, reflecting an impressive footprint of bedrocks particular to this river basin and human activities. Our first-order modern Mississippi River sulfate partition is 25 ± 6% natural and 75% ± 6% anthropogenic sources. Furthermore, anthropogenic coal usage is implicated as the dominant source of modern Mississippi River sulfate, with an estimated 47 ± 5% and 13% of total Mississippi River sulfate due to coal mining and burning, respectively.

    Exposure to radionuclide thorium (Th) has generated widespread public concerns, mainly because of its radiological effects on human health. Activity levels of airborne 232 Th in total suspended particulate (TSP) were measured in the vicinity of the largest rare earth mine in China in August 2012 and March 2013. The mean activity concentrations of 232 Th in TSP ranged from 820μBqm -3 in a mining area in August 2012 to 39,720μBqm -3 in a smelting area in March 2013, much higher than the world reference of 0.5μBqm -3 . Multistatistical analysis and Kohonen's self-organizing maps suggested that 232 Th in TSP was mainly derived from rare earth mining and smelting practices. In addition, personal inhalation exposures to 232 Th associated with respirable particulate (PM 10 ) were also measured among local dwellers via personal monitoring. The mean dose values for different age groups in the smelting and mining areas ranged from 97.86 to 417μSvyear - 1 and from 101.03 to 430.83μSvyear -1 , respectively. These results indicate that people living in the study areas are exposed to high levels of widespread 232 Th. Copyright © 2016 Elsevier B.V. All rights reserved.

    Background Occupational fatality rates among oil and gas extraction industry and specifically among drilling contractor workers are high compared to the U.S. all-industry average. There is scant literature focused on non-fatal injuries among drilling contractors, some of which have introduced engineering controls to improve rig efficiency and reduce injury risk. Methods We compared injury rates on new and old technology rigs operated by the largest U.S. drilling contractor during 2003–2012, stratifying by job type and grouping outcomes by injury severity and body part affected. Results Six hundred seventy-one injuries were recorded over 77.4 million person-hours. The rate on new rigs was 66% of that on old rigs. Roughnecks had lower injury rates on new rigs, largely through reduced limb injury rates. New rigs had lower rates in each non-fatal injury severity category. Conclusions For this company, new technology rigs appear to provide a safer environment for roughnecks. Future studies could include data from additional companies. PMID:25164118

    Full Text Available The aim of this paper is to demonstrate the behavior of the ten largest Brazilian banks between June 2008 and September 2009, based on the analysis of financial indicators. Therefore, 16 three-monthly indices were calculated, extracted from financial statement information, which characterizes a documentary research. The indices were separated in five categories: liquidity, capital, profitability, income and market. The obtained results appointed that most financial institutions in the sample were able to manage their resources so as to gain conditions to maintain credit initially. Then, as from the first term of 2009, driven by public banks, they increased their credit operations. In addition, most banks revealed an anti-cyclical trend to encourage productive activities, preferably activities with higher liquidity levels, to the detriment of profitability, which reveals a more conservative attitude. Finally, it was verified that government initiatives, the Brazilian economic balance and the resources the banks offered helped to produce an environment to reactivate business activities during the most acute period of the subprime crisis.

    Various types of equipment to transport tar sands to processing plants are discussed, with special attention to the advantages of hydraulic direct drives over conventional electro-mechanical drives. A hydraulic direct drive such as the Hagglund Drive has exceptional starting torque capacity due to the high torque capability of the hydraulic motor. As such, it can be particularly useful in applications where shock loads occur with some frequency, or where many starts and stops are needed. Application of the Hagglund drive to power one of the world`s largest apron feeders in the Alberta Oil Sands is described as an illustration of the exceptional reliability, productivity and performance of this equipment. It has about one five-hundredth of the inertia of an equivalent high speed drive with gear reducer, a feature which is particularly significant in the case of feeders which are known to suffer much downtime due to chain related problems. These types of drives have also been used to great advantage in the process industries like pulp and paper, chemical, rubber and plastics, recycling and steel. 1 tab., 1 fig.
