The red blood cell parasite 'Candidatus Mycoplasma haemolamae', formerly Eperythrozoon, is known to be widespread in South American camelids in the USA, causing anaemia in affected animals. Up to now, haemotrophic mycoplasmas were not observed in South American camelids in Europe; however, they were known in a herd of alpacas in Switzerland and to identify them as 'Candidatus M. haemolamae'. Possible ways of transmission are discussed.

Bell, Carl C; Chimata, Radhika

2015-05-01

This study examined the point prevalence of neurodevelopmental disorders among predominantly low-income, African-American psychiatric patients at Jackson Park Hospital's Family Medicine Clinic on Chicago's South Side. Using active case ascertainment methodology, the authors assessed the records of 611 psychiatric patients visiting the clinic between May 23, 2013, and January 14, 2014, to identify those with DSM-5 neurodevelopmental disorders. A total of 297 patients (49%) met criteria for a neurodevelopmental disorder during childhood. Moreover, 237 (39%) had clinical profiles consistent with neurobehavioral disorder associated with prenatal alcohol exposure, and 53 (9%) had other neurodevelopmental disorders. The authors disagreed on the specific type of neurodevelopmental disorder of seven (1% of 611) of the 297 patients with neurodevelopmental disorders. A high prevalence of neurodevelopmental disorders was found among low-income predominantly African-American psychiatric patients on Chicago's South Side. If replicated, these findings should bring about substantial changes in medical practice with African-American patients.

The idea of establishing a South American Space Agency (SASA) is not new. There have been many discussions about this topic for a couple of decades, including an agreement by the Union of South American Nations to create such a space agency. Roughly 10 years ago, Argentina was the first to propose this collaboration with a military orientation. As the ideas progressed, Brazil was proposed to host its headquarters. However, not much support from the South American region has been given, either financially or logistically. To this day, a South American Space Agency or a similar concept has not yet been established in the region. The Space Generation Advisory Council (SGAC) hosted the first South American Space Generation Workshop in Argentina in 2015, where one of the working groups was tasked to further investigate the feasibility, advantages and challenges of implementing SASA. This paper presents an extension of the main findings from this working group where South American students and young professionals study and present a rationale in favor of SASA, outlining possible solutions and a structure that could be taken into account for its implementation. This paper pays particular attention to the question: Is it possible for countries in South America to establish the kind of cooperation necessary to stimulate the development and application of capabilities in the space sector, which would then enable undertaking missions far beyond the scope of what any single country in South America could do on its own? The existence of SASA would allow access to a common representative agency, which would lower costs, be accessible to all participating countries, and allow engagement with other emerging and established space agencies around the world.

2016-04-01

Spirituality has been regarded as an individual and private matter; consequently, research on spirituality as a family phenomenon has been largely neglected. In addition, most published research has been focused on Western cultures. The purpose of this study was to explore the experience of family spirituality and how it influences health among Korean-American elderly couples who are the first generation to reside in the Southeastern USA. A thematic and interpretive data analysis method was used. Thirteen elderly couples (N = 26) participated in in-depth individual interviews in Korean with the primary author. Interviews were audio-taped, transcribed, and then translated by two bilingual researchers with a background in Korean and American culture. Three main themes of family spirituality were identified: (1) family togetherness, (2) family interdependence, and (3) family coping. Also, participants reported that family spirituality strengthened family health by fostering family commitment, improving emotional well-being, developing new healthy behaviors, and providing healing experiences. This finding implies that healthcare providers need to assess family spiritual issues of elderly couples to maximize their strengths for coping with health problems. As our society becomes more culturally diverse, healthcare providers should seek to understand family spirituality from different cultural perspectives to develop a more holistic approach to care.

Full Text Available Objective: The purpose of this study was to describe the well-being of a sample of families from low socioeconomic communities in the Western Cape South Africa in terms of family resilience, family satisfaction, parenting styles, family structure and family functioning. Methods: The study used a descriptive survey design and sampled 358 adult family members. Results: The results indicate that although family functioning is challenged, parents are perceived to be using an authoritative parenting style and having a father present enhances family satisfaction. The results also describe families as displaying low-to-average levels of family resilience. Conclusion: This study provides a descriptive study of a sample of families in the Western Cape, South Africa. Overall the families in this study are not doing very well. The implications and significance of these findings are further explained.

Bell-Tolliver, LaVerne; Burgess, Ruby; Brock, Linda J

2009-07-01

With the exception of Hill's (1971, 1999) work, historically much of the literature on African American families has focused more on pathology than strengths. This study used interviews with 30 African American psychotherapists, self-identified as employing a strengths perspective with African American families, to investigate which strengths they identified in the families and how they use those strengths in therapy. Themes emerging from data analysis confirmed the continued importance of the five strengths Hill noted. In addition, two new strengths were identified by the participants: a willingness of a greater number of families to seek therapy, and the importance of family structure. Strategies used in engaging the families in therapy and practice implications for family therapists are discussed.

Population specific genetic heterogeneity of familial hypercholesterolemia in South Africa.

Smyth, Natalie; Ramsay, Michèle; Raal, Frederick J

2018-04-01

To describe the prevalence and population-specific genetic heterogeneity of familial hypercholesterolemia in South Africa. This review highlights the paucity of data on familial hypercholesterolemia in South Africa, and the urgent need to uncover the mutation profiles in lipid-associated genes, causing an increase in LDL-cholesterol in the different ethnic groups. Case reports and small studies have shown that familial hypercholesterolemia, although apparently uncommon, is present in black Africans. Local founder effects have led to an increased prevalence of familial hypercholesterolemia in several South African populations: Afrikaner founder mutations (c.681 C>G, c.1285 G>A, c.523 G>A), Ashkenazi founder mutation (c.654_656del) and possible Indian founder mutation (c.2054 C>T). Preliminary data in black Africans with elevated LDL-cholesterol identified a possible common mutation, c.137_142del. The South African multiethnic society and well described founder effects emphasize the need for differential approaches to diagnosis and management of familial hypercholesterolemia. Studies involving larger cohorts and inclusive of different ethnicities are paramount to establishing an accurate prevalence of familial hypercholesterolemia in black Africans, not only in South Africa but in the Sub-Saharan African region. It is clear that the estimated world prevalence of one in 250 cannot be generally applied across African populations.

While about 40% of the South American Indian populations (Atacameños, Mapuche, Shuara) were found to be deficient in aldehyde dehydrogenase isozyme I (ALDH2 or E2), preliminary investigations showed very low incidence of isozyme deficiency among North American natives (Sioux, Navajo) and Mexican Indians (mestizo). Possible implications of such trait differences on cross-cultural behavioral response to alcohol drinking are discussed. PMID:3953578

Family eating and physical activity practices among African American, Filipino American, and Hispanic American families: Implications for developing obesity prevention programs

Full Text Available Overweight and obesity among children and adults is well-documented as an escalating problem. The purpose of this study is to determine the blood pressure, self-esteem, and eating and physical activity practices among African Americans, Filipino Americans, and Hispanic Americans; and project implications for development of childhood obesity prevention programs. This descriptive study was conducted in a convenience sample of 110 mothers recruited in health clinics and community centers located in Southeast Florida: 19% African Americans, 26% Filipino Americans, and 55% Hispanic Americans. The data, collected via self-administered questionnaires and a guided interview (Family Eating and Activity Habits Questionnaire, Rosenberg’s Self-Esteem Scale, Background Information Questionnaire, were analyzed via descriptive and inferential statistics with findings significant at p < .05. Results revealed differences and similarities in eating and activity practices between Filipinos and Blacks or Hispanics. Blood pressure and self-esteem did not differ by ethnicity; however, overweight mothers tended to have overweight children. The results point clearly to the importance of the mothers’ role modeling in eating and physical activity practices of families, reflecting the influence of mothers’ behaviors in children’s healthy behaviors, albeit family health. Given that mothers own physical exercise and eating habits could influence their children’s physical activity levels and food choices, a parental advice strategy could be disseminated directly to parents by health professionals. Study findings may raise public awareness of the increasing prevalence and consequences of overweight and obesity in children and adolescents, particularly among vulnerable ethnic groups. The findings provide a database for nurse practitioners and other health service providers for the development of culturally sensitive focused public health education programs to prevent

van Esch, Suzanne C M; Cornel, Martina C; Geelhoed-Duijvestijn, Petronella H L M; Snoek, Frank J

2012-04-01

To explore the possibility of utilizing family communication as a diabetes prevention strategy, specifically targeting high-risk families with South-Asian ancestry in The Netherlands. In a cross-sectional study, type 2 diabetes patients from Dutch (n=311) and Surinamese South-Asian (n=157) origin filled in a questionnaire assessing socio-demographic characteristics, beliefs and concerns about familial diabetes risk, primary prevention, and diabetes-related family communication. Discussing diabetes is regarded acceptable in most families. Especially Surinamese South-Asian patients (68%) seemed motivated to convey risk messages to their relatives; they reported a higher risk perception and expressed more concern than Dutch patients. While 40% in both groups thought relatives are able to prevent developing diabetes, 46% in Dutch and 33% in Surinamese South-Asian patients were unsure. Promoting family communication appears a feasible strategy in diabetes prevention in high-risk (Surinamese South-Asian) families. Health care providers should address patients' concern and emphasize opportunities for prevention. Findings favor training of clinicians in utilizing a family approach as prevention strategy. Patients (particularly Surinamese South-Asians) are in need of professional help in the process of family risk disclosure. (Online) Educational tools should be made available at which patients can refer their relatives. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Paternal Hostility and Maternal Hostility in European American and African American Families.

Wu, Ed Y; Reeb, Ben T; Martin, Monica J; Gibbons, Frederick X; Simons, Ronald L; Conger, Rand D

2014-06-01

The authors examined the hypothesized influence of maternal and paternal hostility on youth delinquency over time. The investigation addressed significant gaps in earlier research on parental hostility, including the neglect of father effects, especially in African American families. Using prospective, longitudinal data from community samples of European American (n = 422) and African American (n = 272) 2-parent families, the authors examined the independent effects of paternal and maternal hostility on youth delinquency. The results indicated that paternal hostility significantly predicted relative increases in youth delinquent behaviors above and beyond the effects of maternal hostility; conversely, maternal hostility did not predict youth delinquency after controlling for paternal hostility. Multiple-group analyses yielded similar results for both ethnic groups and for boys and girls. These results underscore the importance of including both parents in research on diverse families. Neglecting fathers provides an incomplete account of parenting in relation to youth development.

2010-08-01

Full Text Available South Asian American participants of a co-ethnic basketball league, known as Indo-Pak Basketball, utilized urban basketball vernacular through the phrase “liting it up” to identify individuals scoring points in great numbers. The person “liting it up” becomes visible and receives recognition. Accordingly, I want to “lite up” the scholarship on South Asian America whereby situating South Asian American religious sites and cultural centers as key arenas for “Americanization” through US popular culture. I situate sport as a key element of popular culture through which South Asian American communities work out, struggle through, and contest notions of self. Informed by an Anthropology of Sport, ethnography of South Asian American communities in Atlanta takes place alongside an examination of the North American Indo-Pak Basketball circuit. Accordingly, my findings indicate that such community formation has also taken shape at the intersections of institutions, gender, and sexuality whereby excluding queers, women, and other communities of color.

Couples' cultural values, shared parenting, and family emotional climate within Mexican American families.

Science.gov (United States)

Sotomayor-Peterson, Marcela; Figueredo, Aurelio J; Christensen, Donna H; Taylor, Angela R

2012-06-01

This study tested a model of shared parenting as its centerpiece that incorporates cultural values as predictors and family emotional climate as the outcome variable of interest. We aimed to assess the predictive power of the Mexican cultural values of familismo and simpatia over couples' shared parenting practices. We anticipated that higher levels of shared parenting would predict family emotional climate. The participants were 61 Mexican American, low income couples, with at least one child between 3 and 4 years of age, recruited from a home-based Head Start program. The predictive model demonstrated excellent goodness of fit, supporting the hypothesis that a positive emotional climate within the family is fostered when Mexican American couples practice a sufficient level of shared parenting. Empirical evidence was previously scarce on this proposition. The findings also provide evidence for the role of cultural values, highlighting the importance of family solidarity and avoidance of confrontation as a pathway to shared parenting within Mexican American couples. © FPI, Inc.

Juon, Hee-Soon; Rimal, Rajiv N; Klassen, Ann; Lee, Sunmin

2017-12-01

Individuals' behaviors are influenced by those of others in their social environment (i.e., descriptive norms), as well as by how individuals perceive they should behave in that environment (e.g., injunctive norms). Although social norms are thought to play an important role in hepatitis B virus (HBV) screening, limited theoretical or empirical guidance exists on how the underlying process works. In addition, norms are social phenomena that are spread through family discussion about the importance of getting HBV screening. Using the theory of normative social behavior (TNSB), this study examined the roles of injunctive norms (IN), descriptive norms (DN), and family discussion in HBV screening behavior among Asian Americans. Data from a survey of Asian Americans in the Baltimore Washington metropolitan area (N = 877) were used to test underlying theoretical propositions. DN and family discussion emerged as key factors in HBV screening behavior among all Asian Americans. IN were associated with HBV screening among Chinese and Korean Americans, but not for Vietnamese Americans. Family discussion moderated the influence of DN on behavior among Chinese and Vietnamese Americans. However, the main effect of DN on screening behavior was not modified by IN (no interactions between DN and IN). The results indicate that family discussion and social norms are integral in enabling Asian Americans to undergo HBV screening and warrant sensitivity in the design and implementation of a liver cancer prevention program in this high-risk group of Asian Americans.

Ecogeographical Variation in Skull Shape of South-American Canids: Abiotic or Biotic Processes?

Science.gov (United States)

de Moura Bubadué, Jamile; Cáceres, Nilton; Dos Santos Carvalho, Renan; Meloro, Carlo

Species morphological changes can be mutually influenced by environmental or biotic factors, such as competition. South American canids represent a quite recent radiation of taxa that evolved forms very disparate in phenotype, ecology and behaviour. Today, in the central part of South America there is one dominant large species (the maned wolf, Chrysocyon brachyurus ) that directly influence sympatric smaller taxa via interspecific killing. Further south, three species of similar sized foxes ( Lycalopex spp.) share the same habitats. Such unique combination of taxa and geographic distribution makes South American dogs an ideal group to test for the simultaneous impact of climate and competition on phenotypic variation. Using geometric morphometrics, we quantified skull size and shape of 431 specimens belonging to the eight extant South American canid species: Atelocynus microtis , Cerdocyon thous , Ch. brachyurus , Lycalopex culpaeus , L. griseus , L. gymnocercus , L. vetulus and Speothos venaticus . South American canids are significantly different in both skull size and shape. The hypercarnivorous bush dog is mostly distinct in shape from all the other taxa while a degree of overlap in shape-but not size-occurs between species of the genus Lycalopex . Both climate and competition impacts interspecific morphological variation. We identified climatic adaptations as the main driving force of diversification for the South American canids. Competition has a lower degree of impact on their skull morphology although it might have played a role in the past, when canid community was richer in morphotypes.

2013-01-01

Despite the rapidly growing Mexican American population, no studies to date have attempted to explain the underlying relations between family instability and Mexican American children's development. Using a diverse sample of 740 Mexican American adolescents (49% female; 5th grade M age = 10.4; 7th grade M age = 12.8) and their mothers, we prospectively examined the relations between family instability and adolescent academic outcomes and mental health in the 7th grade. The model fit the data well and results indicated that family instability between 5th and 7th grade was related to increased 7th grade mother-adolescent conflict and in turn, mother-adolescent conflict was related to decreased school attachment and to increased externalizing and internalizing symptoms in the 7th grade. Results also indicated that 7th grade mother-adolescent conflict mediated the relations between family instability and 7th grade academic outcomes and mental health. Further, we explored adolescent familism values as a moderator and found that adolescent familism values served as a protective factor in the relation between mother-adolescent conflict and grades. Implications for future research and intervention strategies are discussed. PMID:23750521

Anastrepha fraterculus, the South American fruit fly, is the most common and economically important pest for the fruit-bearing species in the Neotropical region. However, there are some species that are close to A. fraterculus and, sometimes they can be erroneously identified as A. fraterculus. The separation of A. fraterculus from A. obliqua, A. sororcula and A. zenildae, species closely related to South American fruit fly, is discussed. Also, information on the host plants and braconid parasitoids for A. fraterculus in Brazil is presented. (author)

Insight into American tourists’ experiences with weather in South Africa

Directory of Open Access Journals (Sweden)

Giddy Julia K.

2017-12-01

Full Text Available Weather and climate are often important factors determining the success of a tourism destination and resultant satisfaction among tourists. This is particularly true for South Africa due the predominance of outdoor tourist attractions. Increasing numbers of international tourists have visited South Africa since the fall of apartheid, particularly those from the United States (U.S., which is an important market for South African tourism. Therefore, this paper seeks to examine a sample of American tourists’ experience with day-to-day weather and climatic conditions in South Africa. The results show that although respondents did not feel that climatic conditions were an important factor in motivations to visit the country, the day-to-day weather did often impact the enjoyment of their visit. Most notably, weather controlled their ability to participate in outdoor activities. In correlating accounts of unpleasant weather conditions with the meteorological records, a close association emerged, particularly for excessively high temperatures. This indicates that the experiences of American tourists are an accurate indication of climatic unsuitability for tourism, which poses threats to the South African outdoor tourism sector.

Family medicine training in sub-Saharan Africa: South-South cooperation in the Primafamed project as strategy for development.

Health-care systems based on primary health care (PHC) are more equitable and cost effective. Family medicine trains medical doctors in comprehensive PHC with knowledge and skills that are needed to increase quality of care. Family medicine is a relatively new specialty in sub-Saharan Africa. To explore the extent to which the Primafamed South-South cooperative project contributed to the development of family medicine in sub-Saharan Africa. The Primafamed (Primary Health Care and Family Medicine Education) project worked together with 10 partner universities in sub-Saharan Africa to develop family medicine training programmes over a period of 2.5 years. A SWOT (strengths, weaknesses, opportunities and threats) analysis was done and the training development from 2008 to 2010 in the different partner universities was analysed. During the 2.5 years of the Primafamed project, all partner universities made progress in the development of their family medicine training programmes. The SWOT analysis showed that at both national and international levels, the time is ripe to train medical doctors in family medicine and to integrate the specialty into health-care systems, although many barriers, including little awareness, lack of funding, low support from other specialists and reserved support from policymakers, are still present. Family medicine can play an important role in health-care systems in sub-Saharan Africa; however, developing a new discipline is challenging. Advocacy, local ownership, action research and support from governments are necessary to develop family medicine and increase its impact. The Primafamed project showed that development of sustainable family medicine training programmes is a feasible but slow process. The South-South cooperation between the ten partners and the South African departments of family medicine strengthened confidence at both national and international levels. © The Author 2014.

Slattery, J P; Johnson, W E; Goldman, D; O'Brien, S J

1994-09-01

Phylogenetic associations among six closely related South American felid species were defined by changes in protein-encoding gene loci. We analyzed proteins isolated from skin fibroblasts using two-dimensional electrophoresis and allozymes extracted from blood cells. Genotypes were determined for multiple individuals of ocelot, margay, tigrina, Geoffroy's cat, kodkod, and pampas cat at 548 loci resolved by two-dimensional electrophoresis and 44 allozyme loci. Phenograms were constructed using the methods of Fitch-Margoliash and neighbor-joining on a matrix of Nei's unbiased genetic distances for all pairs of species. Results of a relative-rate test indicate changes in two-dimensional electrophoresis data are constant among all South American felids with respect to a hyena outgroup. Allelic frequencies were transformed to discrete character states for maximum parsimony analysis. Phylogenetic reconstruction indicates a major split occurred approximately 5-6 million years ago, leading to three groups within the ocelot lineage. The earliest divergence led to Leopardus tigrina, followed by a split between an ancestor of an unresolved trichotomy of three species (Oncifelis guigna, O. geoffroyi, and Lynchailuris colocolo) and a recent common ancestor of Leopardus pardalis and L. wiedii. The results suggest that modern South American felids are monophyletic and evolved rapidly after the formation of the Panama land bridge between North and South America.

Full Text Available We report, for the first time, the presence of ungulate malaria parasites in South America. We conducted PCR-based surveys of blood samples of multiple deer species and water buffalo from Brazil and detected Plasmodium sequences from pampas deer (Ozotoceros bezoarticus samples. Phylogenic analysis revealed that the obtained sequences are closely related to the Plasmodium odocoilei clade 2 sequence from North American white-tailed deer (Odocoileus virginianus. Nucleotide differences suggest that malaria parasites in South American pampas deer and North American P. odocoilei clade 2 branched more recently than the Great American Interchange.

2015-08-01

International medical electives are well-accepted in medical education, with the flow of students generally being North-South. In this article we explore the learning outcomes of Rwandan family medicine residents who completed their final year elective in South Africa. We compare the learning outcomes of this South-South elective to those of North-South electives from the literature. In-depth interviews were conducted with Rwandan postgraduate family medicine residents who completed a 4-week elective in South Africa during their final year of training. The interviews were thematically analysed in an inductive way. The residents reported important learning outcomes in four overarching domains namely: medical, organisational, educational, and personal. The learning outcomes of the residents in this South-South elective had substantial similarities to findings in literature on learning outcomes of students from the North undertaking electives in the Southern hemisphere. Electives are a useful learning tool, both for Northern students, and students from universities in the South.

New views on American colonization: critical tests from South America

Directory of Open Access Journals (Sweden)

O'Rourke, Dennis

2007-01-01

Full Text Available The traditional view of colonization of the Americas as a migration across Beringia and subsequent dispersal southward following the last glacial maximum is being increasingly questioned. In North America, archaeological links to Siberia are tenuous and genetic data are more consistent with an earlier entry of people into the Americas, from Central rather than Northeast Siberia. An entry of populations into the Americas prior to the last glacial maximum forces a reconsideration not only of timing, but also geographic points of entry and speed of dispersal, based on ecological theory. A number of emerging alternative hypotheses on the colonization of the Americas predict early entry and dispersal of people into South America - earlier than, or coeval with, initial dispersal in North America. The study of genetic, morphological, and archaeological variation across South America is critical to testing these new, alternative hypotheses of Native American origins. I will review the evidence for emerging, alternative views of American Colonization, and suggest ways in which data from South American populations and prehistory will be crucial in testing them.

Nguyen, Ann W; Taylor, Robert Joseph; Chatters, Linda M; Taylor, Harry Owen; Lincoln, Karen D; Mitchell, Uchechi A

2017-03-01

This study examined the relationship between informal social support from extended family and friends and suicidality among African Americans. Logistic regression analysis was based on a nationally representative sample of African Americans from the National Survey of American Life (N = 3263). Subjective closeness and frequency of contact with extended family and friends and negative family interaction were examined in relation to lifetime suicide ideation and attempts. Subjective closeness to family and frequency of contact with friends were negatively associated with suicide ideation and attempts. Subjective closeness to friends and negative family interaction were positively associated with suicide ideation and attempts. Significant interactions between social support and negative interaction showed that social support buffers against the harmful effects of negative interaction on suicidality. Findings are discussed in relation to the functions of positive and negative social ties in suicidality.

Family matters: Familial support and science identity formation for African American female STEM majors

Science.gov (United States)

Parker, Ashley Dawn

This research seeks to understand the experiences of African American female undergraduates in STEM. It investigates how familial factors and science identity formation characteristics influence persistence in STEM while considering the duality of African American women's status in society. This phenomenological study was designed using critical race feminism as the theoretical framework to answer the following questions: 1) What role does family play in the experiences of African American women undergraduate STEM majors who attended two universities in the UNC system? 2) What factors impact the formation of science identity for African American women undergraduate STEM majors who attended two universities in the UNC system? Purposive sampling was used to select the participants for this study. The researcher conducted in-depth interviews with 10 African American female undergraduate STEM major from a predominantly White and a historically Black institution with the state of North Carolina public university system. Findings suggest that African American families and science identity formation influence the STEM experiences of the African American females interviewed in this study. The following five themes emerged from the findings: (1) independence, (2) support, (3) pressure to succeed, (4) adaptations, and (5) race and gender. This study contributes to the literature on African American female students in STEM higher education. The findings of this study produced knowledge regarding policies and practices that can lead to greater academic success and persistence of African American females in higher education in general, and STEM majors in particular. Colleges and universities may benefit from the findings of this study in a way that allows them to develop and sustain programs and policies that attend to the particular concerns and needs of African American women on their campuses. Finally, this research informs both current and future African American female

Kim, Chang-Jun

2016-04-01

Full Text Available Previously only one species, Embolemus ruddii Westwood, 1833, of the family Embolemidae has been recorded in South Korea. As part of a recent study of this family, we newly report four species from South Korea: Embolemus hachijoensis Hirashima et Yamagishi, 1975; E. krombeini Olmi, 1996; E. sensitivus Xu, Olmi et Guglielmino, 2012; Ampulicomorpha thauma Rasnitsyn et Matveev, 1989. The genus, Ampulicomorpha Ashmead, 1893, is recorded for the first time in South Korea. Embolemus ruddii was previously recorded from South Korea because considered synonym of E. walkeri. However, in recent years the two species were separated and E. ruddii was considered absent in the far east, where on the contrary E. walkeri is present. Therefore, five species in two genera are now recognized as the South Korean embolemid fauna. A key to the South Korean Embolemidae species is provided.

Davey, Maureen P; Kissil, Karni; Lynch, Laura; Harmon, La-Rhonda; Hodgson, Nancy

2013-07-01

The primary objective of this 2-year pilot study was to evaluate the effectiveness of a culturally adapted family intervention in improving family communication among African American parents coping with cancer and their school-age children. A secondary objective was to determine its impact on other symptoms of psychosocial distress (depression and anxiety). The third objective was to assess for acceptability and feasibility. Using a two-arm pre-intervention and post-intervention prospective design, 12 African American families received five bi-monthly sessions of either a culturally adapted family intervention (n=7 families) or psycho-education treatment (n=5 families). Parents and their children completed pre-intervention and post-intervention questionnaires assessing perceptions of family communication, quality of their relationship, and symptoms of depression. School-age children additionally completed a questionnaire assessing their levels of anxiety. Consumer satisfaction was also evaluated at post-intervention. Parents and school-age children who completed the culturally adapted family intervention reported significantly better communication with each other and were more satisfied compared with the psycho-education control group. No changes were noted in symptoms of anxiety or depression. The culturally adapted family intervention was acceptable based on our findings, families' feedback, and rates of retention. Feasibility is uncertain because our oncology clinic approach to recruitment was slower than expected. Providing culturally adapted family intervention programs to African American families who are coping with parental cancer may result in improved family communication. This pilot study serves as the first step in the development of culturally adapted family intervention programs to help African American families cope with parental cancer.

The water economy of South American desert rodents: from integrative to molecular physiological ecology.

Science.gov (United States)

Bozinovic, Francisco; Gallardo, Pedro

2006-01-01

Rodents from arid and semi-arid habitats live under conditions where the spatial and temporal availability of free water is limited, or scarce, thus forcing these rodents to deal with the problem of water conservation. The response of rodents to unproductive desert environments and water deficits has been intensively investigated in many deserts of the world. However, current understanding of the cellular, systemic and organismal physiology of water economy relies heavily on short-term, laboratory-oriented experiments, which usually focus on responses at isolated levels of biological organization. In addition, studies in small South American mammals are scarce. Indeed xeric habitats have existed in South America for a long time and it is intriguing why present day South American desert rodents do not show the wide array of adaptive traits to desert life observed for rodents on other continents. Several authors have pointed out that South American desert rodents lack physiological and energetic specialization for energy and water conservation, hypothesizing that their success is based more on behavioral and ecological strategies. We review phenotypic flexibility and physiological diversity in water flux rate, urine osmolality, and expression of water channels in South American desert-dwelling rodents. As far as we know, this is the first review of integrative studies at cellular, systemic and organismal levels. Our main conclusion is that South American desert rodents possess structural as well as physiological systems for water conservation, which are as remarkable as those found in "classical" rodents inhabiting other desert areas of the world.

Radioactive mineral potential of carbonatites in western parts of the South American shields

International Nuclear Information System (INIS)

Premoli, C.; Kroonenberg, S.B.

1984-01-01

During the last eight years at least six carbonatites or clusters of carbonatites have been discovered in the western parts of the South American cratons. In contrast to the carbonatites of the eastern part of the South American shields, which have been well studied and placed in a tectonic context together with the West African carbonatite provinces, those of the western part of the South American cratons have received litte attention. This paper is a compilation of published and original data on these occurrences, their geology, geochemistry, structural setting and radioactive mineral potential. An exploration strategy is devised based on experiences in this rainforest-clad area and the peculiar genetic aspect of carbonatites. Some details of a possibly new uranium mineral encountered in Cerro Cora carbonatite are given. (author)

Discrimination and adjustment among Chinese American adolescents: family conflict and family cohesion as vulnerability and protective factors.

Science.gov (United States)

Juang, Linda P; Alvarez, Alvin A

2010-12-01

We examined racial/ethnic discrimination experiences of Chinese American adolescents to determine how discrimination is linked to poor adjustment (i.e., loneliness, anxiety, and somatization) and how the context of the family can buffer or exacerbate these links. We collected survey data from 181 Chinese American adolescents and their parents in Northern California. We conducted hierarchical regression analyses to examine main effects and 2-way interactions of perceived discrimination with family conflict and family cohesion. Discrimination was related to poorer adjustment in terms of loneliness, anxiety, and somatization, but family conflict and cohesion modified these relations. Greater family conflict exacerbated the negative effects of discrimination, and greater family cohesion buffered the negative effects of discrimination. Our findings highlight the importance of identifying family-level moderators to help adolescents and their families handle experiences of discrimination.

Tenancy and African American Marriage in the Postbellum South.

Science.gov (United States)

Bloome, Deirdre; Muller, Christopher

2015-10-01

The pervasiveness of tenancy in the postbellum South had countervailing effects on marriage between African Americans. Tenancy placed severe constraints on African American women's ability to find independent agricultural work. Freedwomen confronted not only planters' reluctance to contract directly with women but also whites' refusal to sell land to African Americans. Marriage consequently became one of African American women's few viable routes into the agricultural labor market. We find that the more counties relied on tenant farming, the more common was marriage among their youngest and oldest African American residents. However, many freedwomen resented their subordinate status within tenant marriages. Thus, we find that tenancy contributed to union dissolution as well as union formation among freedpeople. Microdata tracing individuals' marital transitions are consistent with these county-level results.

Keratolytic winter erythema (KWE) is a rare autosomal-dominant skin disorder characterized by recurrent episodes of palmoplantar erythema and epidermal peeling. KWE was previously mapped to 8p23.1-p22 (KWE critical region) in South African families. Using targeted resequencing of the KWE critical region in five South African families and SNP array and whole-genome sequencing in two Norwegian families, we identified two overlapping tandem duplications of 7.67 kb (South Africans) and 15.93 kb (Norwegians). The duplications segregated with the disease and were located upstream of CTSB, a gene encoding cathepsin B, a cysteine protease involved in keratinocyte homeostasis. Included in the 2.62 kb overlapping region of these duplications is an enhancer element that is active in epidermal keratinocytes. The activity of this enhancer correlated with CTSB expression in normal differentiating keratinocytes and other cell lines, but not with FDFT1 or NEIL2 expression. Gene expression (qPCR) analysis and immunohistochemistry of the palmar epidermis demonstrated significantly increased expression of CTSB, as well as stronger staining of cathepsin B in the stratum granulosum of affected individuals than in that of control individuals. Analysis of higher-order chromatin structure data and RNA polymerase II ChIA-PET data from MCF-7 cells did not suggest remote effects of the enhancer. In conclusion, KWE in South African and Norwegian families is caused by tandem duplications in a non-coding genomic region containing an active enhancer element for CTSB, resulting in upregulation of this gene in affected individuals.

Brittain, Kelly; Taylor, Jacquelyn Y.; Wu, Chun Yi

2010-01-01

African American women are at greater risk for complications related to high blood pressure. This study examined relationships between high blood pressure, pulse pressure, body mass index, family adaptability, family cohesion and social support among 146 Urban African American women. Significant relationships were found between family adaptability and systolic blood pressure (p = .03) and between adaptability and pulse pressure (p ≤ .01). Based on study results, practitioners should routinely assess family functioning, specifically family adaptability, in African American women who are at risk for high blood pressure or diagnosed with high blood pressure to minimize complications associated with hypertension.

2012-01-01

Objective The aim of this study is to explore behavioral factors associated with toothache among African American adolescents living in rural South Carolina. Methods Using a self-administered questionnaire, data were collected on toothache experience in the past 12 months, oral hygiene behavior, dental care utilization, and cariogenic snack and non-diet soft drink consumption in a convenience sample of 156 African American adolescents aged 10-18 years old living in rural South Carolina. Univariable and multivariable logistic regression analyses were used to assess the associations between reported toothache experience and socio-demographic variables, oral health behavior, and snack consumption. Results Thirty-four percent of adolescents reported having toothache in the past 12 months. In univariable modeling, age, dental visit in the last two years, quantity and frequency of cariogenic snack consumption, and quantity of non-diet soft drink consumption were each significantly associated with experiencing toothache in the past 12 months (all p-values cariogenic snacks, and number of cans of non-diet soft drink consumed during the weekend significantly increased the odds of experiencing toothache in the past 12 months (all p-values ≤ 0.01). Conclusion Findings indicate age, frequent consumption of cariogenic snacks and number of cans of non-diet soft drinks are related to toothache in this group. Public policy implications related to selling cariogenic snacks and soft drink that targeting children and adolescents especially those from low income families are discussed. PMID:22085328

The importance of family factors and generation status: mental health service use among Latino and Asian Americans.

Science.gov (United States)

Chang, Janet; Natsuaki, Misaki N; Chen, Chih-Nan

2013-07-01

The present study utilized data from the National Latino and Asian American Study to examine ethnic and generational differences in family cultural conflict and family cohesion and how the effects of such family conflict and cohesion on lifetime service use vary by generation status for Latino Americans (n = 2,554) and Asian Americans (n = 2,095). Findings revealed that first-generation Asian Americans reported greater family cultural conflict than their Latino counterparts, but third-generation Latino Americans had higher family conflict than their Asian American counterparts. First-generation Latino and Asian Americans had the highest levels of family cohesion. Results from logistic regression analyses indicated that Latino Americans who reported higher family cultural conflict and lower family cohesion were more likely to use mental health services. For Asian Americans, family cultural conflict, but not family cohesion, was associated with service use. Relative to third-generation Asian Americans, second-generation Asian Americans with higher family cultural conflict were more likely to use mental health services. Given that cohesive familial bonds appear to discourage service use on the part of Latino Americans irrespective of generation status, further research is needed to ascertain the extent to which this tendency stems from greater reliance on family support as opposed to the stigma associated with mental health treatment. Mental health providers and treatment programs need to address the role of family cultural conflict in the lives of Asian Americans, particularly second generation, and Latino Americans across generations, because conflictual family ties may motivate help-seeking behaviors and reveal substantial underlying distress.

2015-01-01

This qualitative study examined patterns of communication regarding family health history among older African American adults. The authors conducted 5 focus groups and 6 semi-structured interviews with African Americans aged 60 years and older (N = 28). The authors identified 4 distinct patterns of family health history communication: noncommunication, open communication, selective communication (communication restricted to certain people or topics), and one-way communication (communication not reciprocated by younger family members). In general, participants favored open family health history communication, often resulting from desires to change patterns of noncommunication in previous generations regarding personal and family health history. Some participants indicated that they were selective about what and with whom they shared health information in order to protect their privacy and not worry others. Others described family health history communication as one-way or unreciprocated by younger family members who appeared uninterested or unwilling to share personal and family health information. The communication patterns that the authors identified are consistent with communication privacy management theory and with findings from studies focused on genetic testing results for hereditary conditions, suggesting that individuals are consistent in their communication of health and genetic risk information. Findings may guide the development of health message strategies for African Americans to increase family health history communication.

Wang, Jong-Yi; Probst, Janice C; Moore, Charity G; Martin, Amy B; Bennett, Kevin J

2011-08-01

We examined the prevalence of and factors associated with violent and heated disagreements in the Asian American families, with an emphasis on place of birth differences between parent and child. Data were obtained from the 2003 National Survey of Children's Health, limited to five states with the highest concentration of Asian-Americans (n = 793). Multivariable analysis used generalized logistic regression models with a three-level outcome, violent and heated disagreement versus calm discussion. Violent disagreements were reported in 13.7% of Asian-American homes and 9.9% of white homes. Differential parent-child place of birth was associated with increased odds for heated disagreement in Asian-American families. Parenting stress increased the likelihood of violent disagreements in both Asian-American and white families. Asian-American families are not immune to potential family violence. Reducing parenting stress and intervening in culturally appropriate ways to reduce generation differences should be violence prevention priorities.

Communication, coping, and quality of life of breast cancer survivors and family/friend dyads: a pilot study of Chinese-Americans and Korean-Americans.

Lim, Jung-Won

2014-11-01

This study aimed to understand the dyadic relationships between family communication and quality of life (QOL) and between coping and QOL in Chinese-American and Korean-American breast cancer survivor (BCS)-family member dyads. A cross-sectional survey design was used. A total of 32 Chinese-American and Korean-American BCS-family member dyads were recruited from the California Cancer Surveillance Program and area hospitals in Los Angeles County, California, USA. The dyadic data were analyzed using a pooled regression actor-partner interdependence model. The study findings demonstrated that the survivors' general communication and use of reframing coping positively predicted their own QOL. The survivors' and family members' general communication was also a strong predictor of the family members' physical-related QOL score specifically. Meanwhile, each person's use of mobilizing coping negatively predicted his or her partner's QOL. The study findings add important information to the scarce literature on the QOL of Asian-American survivors of breast cancer. The findings suggest that Chinese-American and Korean-American BCS and their family members may benefit from interventions that enhance communication and coping within the family unit.

McCabe, Kristen; Yeh, May; Lau, Anna; Argote, Carolina Bertely; Liang, June

2009-01-01

This study compared low-income Mexican American parents of young children referred for behavior problems to their nonreferred counterparts on an observational measure of parent-child interactions. Referred Mexican American parents demonstrated more negative behaviors than their nonreferred counterparts in both nondirective and highly directive situations. However, no differences were found at moderate levels of directiveness. The most and least directive situations in the Dyadic Parent-Child Interaction Coding System best differentiated referred from nonreferred Mexican American families, and families differed more in their negative behaviors than positive behaviors. Many of the parenting behaviors that have been found to differ between referred and nonreferred Caucasian families were also observed to differ between their Mexican American counterparts.

Reciprocal Family, Friendship and Church Support Networks of African Americans: Findings from the National Survey of American Life.

Science.gov (United States)

Taylor, Robert Joseph; Mouzon, Dawne M; Nguyen, Ann W; Chatters, Linda M

2016-12-01

This study examined reciprocal support networks involving extended family, friends and church members among African Americans. Our analysis examined specific patterns of reciprocal support (i.e., received only, gave only, both gave and received, neither gave or received), as well as network characteristics (i.e., contact and subjective closeness) as correlates of reciprocal support. The analysis is based on the African American sub-sample of the National Survey of American Life (NSAL). Overall, our findings indicate that African Americans are very involved in reciprocal support networks with their extended family, friends and church members. Respondents were most extensively involved in reciprocal supports with extended family members, followed closely by friends and church networks. Network characteristics (i.e., contact and subjective closeness) were significantly and consistently associated with involvement with reciprocal support exchanges for all three networks. These and other findings are discussed in detail. This study complements previous work on the complementary roles of family, friend and congregational support networks, as well as studies of racial differences in informal support networks.

The Pleistocenic Arc Hypothesis (PAH) posits that South American Seasonally Dry Tropical Forests (SDTF) were interconnected during Pleistocene glacial periods, enabling the expansion of species ranges that were subsequently fragmented in interglacial periods, promoting speciation. The lizard genus Lygodactylus occurs in Africa, Madagascar, and South America. Compared to the high diversity of African Lygodactylus, only two species are known to occur in South America, L. klugei and L. wetzeli, distributed in SDTFs and the Chaco, respectively. We use a phylogenetic approach based on mitochondrial (ND2) and nuclear (RAG-1) markers covering the known range of South American Lygodactylus to investigate (i) if they are monophyletic relative to their African congeners, (ii) if their divergence is congruent with the fragmentation of the PAH, and (iii) if cryptic diversity exists within currently recognized species. Maximum likelihood and Bayesian phylogenetic analyses recovered a well-supported monophyletic South American Lygodactylus, presumably resulting from a single trans-Atlantic dispersal event 29 Mya. Species delimitation analyses supported the existence of five putative species, three of them undescribed. Divergence times among L. klugei and the three putative undescribed species, all endemic to the SDTFs, are not congruent with the fragmentation of the PAH. However, fragmentation of the once broader and continuous SDTFs likely influenced the divergence of L. wetzeli in the Chaco and Lygodactylus sp. 3 (in a SDTF enclave in the Cerrado).

Parent-adolescent conflict is frequent in families and has implications for youth adjustment and family relationships. Drawing on a family systems perspective, we examined mothers', fathers', and two adolescent-aged siblings' (50.5 % females) reports of parent-adolescent conflict in 187 African American families. Using latent profile analysis in the context of an ethnic homogeneous design, we identified three family types based on levels of and differences between parent and youth conflict reports: low conflict, father high conflict, and younger sibling high conflict. Compared to low conflict families, youth in younger sibling high conflict families reported more depressive symptoms and risky behaviors. The results for parents' acceptance revealed that, in comparison to low conflict families, older siblings in father high conflict families reported lower acceptance from mothers, and mothers in these families reported lower acceptance of their children; further, older siblings in younger sibling high conflict families reported less acceptance from fathers, and fathers in these families reported less acceptance of their children. Results underscore the significance of levels of and both differences between and direction of differences in parents' and youth's reports of their "shared" experiences, as well as the importance of examining the larger family contexts of dyadic parent-relationships.

2009 South American benchmarking study: natural gas transportation companies

Energy Technology Data Exchange (ETDEWEB)

Jordan, Nathalie [Gas TransBoliviano S.A. (Bolivia); Walter, Juliana S. [TRANSPETRO, Rio de Janeiro, RJ (Brazil)

2009-07-01

In the current business environment large corporations are constantly seeking to adapt their strategies. Benchmarking is an important tool for continuous improvement and decision-making. Benchmarking is a methodology that determines which aspects are the most important to be improved upon, and it proposes establishing a competitive parameter in an analysis of the best practices and processes, applying continuous improvement driven by the best organizations in their class. At the beginning of 2008, GTB (Gas TransBoliviano S.A.) contacted several South American gas transportation companies to carry out a regional benchmarking study in 2009. In this study, the key performance indicators of the South American companies, whose reality is similar, for example, in terms of prices, availability of labor, and community relations, will be compared. Within this context, a comparative study of the results, the comparative evaluation among natural gas transportation companies, is becoming an essential management instrument to help with decision-making.

Chesla, Catherine A; Chun, Kevin M; Kwan, Christine M L

2009-10-01

Although Asians demonstrate elevated levels of type 2 diabetes, little attention has been directed to their unique cultural beliefs and practices regarding diabetes. We describe cultural and family challenges to illness management in foreign-born Chinese American patients with type 2 diabetes and their spouses. This was an interpretive comparative interview study with 20 foreign-born Chinese American couples (n = 40) living with type 2 diabetes. Multiple (six to seven) semistructured interviews with each couple in individual, group, and couple settings elicited beliefs about diabetes and narratives of care within the family and community. Interpretive narrative and thematic analysis were completed. A separate respondent group of 19 patients and spouses who met the inclusion criteria reviewed and confirmed the themes developed from the initial couples. Cultural and family challenges to diabetes management within foreign-born Chinese American families included how 1) diabetes symptoms challenged family harmony, 2) dietary prescriptions challenged food beliefs and practices, and 3) disease management requirements challenged established family role responsibilities. Culturally nuanced care with immigrant Chinese Americans requires attentiveness to the social context of disease management. Patients' and families' disease management decisions are seldom made independent of their concerns for family well-being, family face, and the reciprocal responsibilities required by varied family roles. Framing disease recommendations to include cultural concerns for balance and significant food rituals are warranted.

Effect of acculturation and mutuality on family loyalty among Mexican American caregivers of elders.

Science.gov (United States)

Kao, Hsueh-Fen S; An, Kyungeh

2012-06-01

Informal family care for elders is conventional in Mexican American communities despite increasing intergenerational gaps in filial values. In our study, we explored whether acculturation and dyadic mutuality, as perceived by Mexican American family caregivers, explain the caregivers' expectations of family loyalty toward elderly relatives. A nonexperimental, correlational design with convenience sampling was used in El Paso, Texas, from October 2007 to January 2008. Three bilingual promotoras collected data from 193 Mexican American adult caregivers of community-dwelling elders using three scales designed for Mexican Americans: the Acculturation Rating Scale for Mexican Americans II-Short Form, the Mutuality Scale, and the Expectations of Family Loyalty of Children Toward Elderly Relatives Scale. Confirmatory factor analysis was used to analyze the data. Acculturation had a marginal effect (r = .21, p loyalty toward elderly relatives. There was no significant correlation between acculturation and mutuality (r = .05). Although Mexican American caregivers with strong Mexican orientation may have high expectations of family loyalty toward elderly relatives, mutuality exhibits more significant effects on expectations. Among Mexican Americans, mutuality between the caregiving dyad, as perceived by caregivers, may be a better predictor of filial values than caregivers' acculturation alone. It may be useful to incorporate the dual paradigm of acculturation and mutuality into immigrant family care for elderly relatives. © 2012 Sigma Theta Tau International.

2015-06-01

South Korea's low birth rate, aging society, and female migration to urban areas due to industrialization have caused an accelerated inflow of Asian female immigrants into Korea to marry Korean men, especially in rural areas. This study was performed to determine how family function of multicultural families changes over time and what factors affect the changes in family function of multicultural families. The study subjects were 62 Asian immigrant women married to South Korean men living in South Korea. In a 1st wave study in August 2008, the socioeconomic factors and Family Adaptability and Cohesion Scale III (FACES III) scores were measured. A 3-year follow-up study was then conducted in August 2011, and the results were compared with the 1st wave study results. The mean family adaptability score was 24.6 in the 1st wave study and 26.1 at the 3-year follow-up. The average family cohesion score was 31.0 in the 1st wave study and 36.7 at the 3-year follow-up. There was a statistically significant increase in family cohesion after 3 years (P adaptability did not change over time; however, conversely, family cohesion increased. The age difference between husband and wife and the subjective SES had a positive association with the changes in family cohesion. Copyright © 2013 Wiley Publishing Asia Pty Ltd.

Evaluate the production and the research collaborative network on Leishmaniasis in South America. A bibliometric research was carried out using SCOPUS database. The analysis unit was original research articles published from 2000 to 2011, that dealt with leishmaniasis and that included at least one South American author. The following items were obtained for each article: journal name, language, year of publication, number of authors, institutions, countries, and others variables. 3,174 articles were published, 2,272 of them were original articles. 1,160 different institutional signatures, 58 different countries and 398 scientific journals were identified. Brazil was the country with more articles (60.7%) and Oswaldo Cruz Foundation (FIOCRUZ) had 18% of Brazilian production, which is the South American nucleus of the major scientific network in Leishmaniasis. South American scientific production on Leishmaniasis published in journals indexed in SCOPUS is focused on Brazilian research activity. It is necessary to strengthen the collaboration networks. The first step is to identify the institutions with higher production, in order to perform collaborative research according to the priorities of each country.

Blanco-Verea, A; Jaime, J C; Brión, M; Carracedo, A

2010-04-01

The present work tries to investigate the population structure and variation of the Amerindian indigenous populations living in Argentina. A total of 134 individuals from three ethnic groups (Kolla, Mapuche and Diaguitas) living in four different regions were collected and analysed for 26 Y-SNPs and 11 Y-STRs. Intra-population variability was analysed, looking for population substructure and neighbour populations were considered for genetic comparative analysis, in order to estimate the contribution of the Amerindian and the European pool, to the current population. We observe a high frequency of R1b1 and Q1a3a* Y-chromosome haplogroups, in the ethnic groups Mapuche, Diaguita and Kolla, characteristic of European and Native American populations, respectively. When we compare our native Argentinean population with other from the South America we also observe that frequency values for Amerindian lineages are relatively lower in our population. These results show a clear Amerindian genetic component but we observe a predominant European influence too, suggesting that typically European male lineages have given rise to the displacement of genuinely Amerindian male lineages in our South American population.

Transactional Process of African American Adolescents' Family Conflict and Violent Behavior.

Science.gov (United States)

Choe, Daniel Ewon; Zimmerman, Marc A

2014-12-01

This is the first longitudinal study of urban African American adolescents that has examined bidirectional effects between their family conflict and violent behavior across all of high school. Structured interviews were administered to 681 students each year in high school at ages 15, 16 17, and 18 years. We used structural equation modeling to test a transactional model and found bidirectional effects between family conflict and violent behavior across the middle years of high school, while accounting for sex and socioeconomic status. Findings suggest a reciprocal process involving interpersonal conflict in African American families and adolescent engagement in youth violence.

The impact of the subtropical South Atlantic SST on South American precipitation

A. S. Taschetto

2008-11-01

Full Text Available The Community Climate Model (CCM3 from the National Center for Atmospheric Research (NCAR is used to investigate the effect of the South Atlantic sea surface temperature (SST anomalies on interannual to decadal variability of South American precipitation. Two ensembles composed of multidecadal simulations forced with monthly SST data from the Hadley Centre for the period 1949 to 2001 are analysed.

A statistical treatment based on signal-to-noise ratio and Empirical Orthogonal Functions (EOF is applied to the ensembles in order to reduce the internal variability among the integrations. The ensemble treatment shows a spatial and temporal dependence of reproducibility. High degree of reproducibility is found in the tropics while the extratropics is apparently less reproducible. Austral autumn (MAM and spring (SON precipitation appears to be more reproducible over the South America-South Atlantic region than the summer (DJF and winter (JJA rainfall. While the Inter-tropical Convergence Zone (ITCZ region is dominated by external variance, the South Atlantic Convergence Zone (SACZ over South America is predominantly determined by internal variance, which makes it a difficult phenomenon to predict. Alternatively, the SACZ over western South Atlantic appears to be more sensitive to the subtropical SST anomalies than over the continent.

An attempt is made to separate the atmospheric response forced by the South Atlantic SST anomalies from that associated with the El Niño – Southern Oscillation (ENSO. Results show that both the South Atlantic and Pacific SSTs modulate the intensity and position of the SACZ during DJF. Particularly, the subtropical South Atlantic SSTs are more important than ENSO in determining the position of the SACZ over the southeast Brazilian coast during DJF. On the other hand, the ENSO signal seems to influence the intensity of the SACZ not only in DJF but especially its oceanic branch during MAM. Both local and

Although there is a large literature on the influence of social support on mental health there is limited research on social support and OCD. This is especially the case for African Americans and Black Caribbeans. This study examines the relationship between family and friendship networks and the prevalence of OCD. The analysis is based on the National Survey of American Life a nationally representative sample of African Americans and Black Caribbeans. Variables included frequency of contact with family and friends, subjective closeness with family and friends, and negative interactions (conflict, criticisms) with family members. The results indicated that only negative interaction with family members was significantly associated with OCD prevalence. African Americans and Black Caribbeans with more frequent negative interactions with family members had a higher likelihood of having OCD. Subjective closeness and frequency of contact with family and friends was not protective of OCD. Overall the findings are consistent with previous work which finds that social support is an inconsistent protective factor of psychiatric disorders, but negative interactions with support network members is more consistently associated with mental health problems.

Childhood obesity is a growing problem for children in the United States, especially for children from low-income, African American families. The purpose of this qualitative study was to understand facilitators and barriers to engaging in healthy lifestyles faced by low-income African American children and their families. This qualitative study used semi-structured focus group interviews with eight African American children clinically identified as overweight or obese (BMI ≥ 85) and their parents. An expert panel provided insights in developing culturally appropriate intervention strategies. Child and parent focus group analysis revealed 11 barriers and no definitive facilitators for healthy eating and lifestyles. Parents reported confusion regarding what constitutes nutritional eating, varying needs of family members in terms of issues with weight, and difficulty in engaging the family in appropriate and safe physical activities; to name a few themes. Community experts independently suggested that nutritional information is confusing and, often, contradictory. Additionally, they recommended simple messaging and practical interventions such as helping with shopping lists, meal planning, and identifying simple and inexpensive physical activities. Childhood obesity in the context of low-resource families is a complex problem with no simple solutions. Culturally sensitive and family informed interventions are needed to support low-income African American families in dealing with childhood obesity.

2017-10-15

This study tests the psychometric properties of multiple survey items and scales that are either underused or newly developed to assess familism among Asian Americans. Using data collected from 150 Filipino and 188 Korean American parents (mostly mothers) in the Midwest region in 2013, the measures were examined for validity and reliability for each group and, when appropriate, for cross-cultural equivalence across the groups. Several scales and their items showed high quality psychometric properties and are ready for use to more accurately assess family process of each target group and to conduct comparative analyses. The findings also show that, contrary to the expectation, Filipino American families express more traditional aspects of familism than do Korean American families, and are more likely to reinforce traditional familism beliefs and behaviors among their children. This study reinforces a need for more empirical- and subgroup-specific research effort. © 2017 Family Process Institute.

Potential use of the sterile insect technique against the South American fruit fly

International Nuclear Information System (INIS)

Ortiz, G.

1999-01-01

The Latin American countries have a strong interest in increasing fruit production and quality to facilitate commercialization within and outside the region. Various fruit fly control programmes in South America and their objectives and benefits are described here. Specific priorities to improve fruit fly control and eradication technologies include strengthening of quarantine, development of pre- and post-phytosanitary measures, and harmonization of the most effective and advanced technical procedures/methodologies to control fruit flies. A subregional strategy to control fruit flies in South America would promote technical co-operation among the South American countries and strengthen the activities of less advanced fruit fly programmes. Effective use can be made of local/regional infrastructure, expertise, sterile fly production and human/technical resources. In Argentina, advanced technology related to the use of medfly genetic sexing strains for SIT programmes has been successfully introduced. Joint efforts between technicians and scientists would contribute to developing new technology to control important pests in South America. (author)

Neighborhood Disorder and Children’s Antisocial Behavior: The Protective Effect of Family Support Among Mexican American and African American Families

Science.gov (United States)

Conger, Rand D.; Conger, Katherine J.; Martin, Monica J.; Brody, Gene; Simons, Ronald; Cutrona, Carolyn

2012-01-01

Using data from a sample of 673 Mexican Origin families, the current investigation examined the degree to which family supportiveness acted as a protective buffer between neighborhood disorder and antisocial behavior during late childhood (i.e. intent to use controlled substances, externalizing, and association with deviant peers). Children’s perceptions of neighborhood disorder fully mediated associations between census and observer measures of neighborhood disorder and their antisocial behavior. Family support buffered children from the higher rates of antisocial behavior generally associated with living in disorderly neighborhoods. An additional goal of the current study was to replicate these findings in a second sample of 897 African American families, and that replication was successful. These findings suggest that family support may play a protective role for children living in dangerous or disadvantaged neighborhoods. They also suggest that neighborhood interventions should consider several points of entry including structural changes, resident perceptions of their neighborhood and family support. PMID:22089092

SOUTH AMERICAN COLLABORATION IN SCIENTIFIC PUBLICATIONS ON LEISHMANIASIS: BIBLIOMETRIC ANALYSIS IN SCOPUS (2000-2011

Full Text Available Objectives: Evaluate the production and the research collaborative network on Leishmaniasis in South America. Methods: A bibliometric research was carried out using SCOPUS database. The analysis unit was original research articles published from 2000 to 2011, that dealt with leishmaniasis and that included at least one South American author. The following items were obtained for each article: journal name, language, year of publication, number of authors, institutions, countries, and others variables. Results: 3,174 articles were published, 2,272 of them were original articles. 1,160 different institutional signatures, 58 different countries and 398 scientific journals were identified. Brazil was the country with more articles (60.7% and Oswaldo Cruz Foundation (FIOCRUZ had 18% of Brazilian production, which is the South American nucleus of the major scientific network in Leishmaniasis. Conclusions: South American scientific production on Leishmaniasis published in journals indexed in SCOPUS is focused on Brazilian research activity. It is necessary to strengthen the collaboration networks. The first step is to identify the institutions with higher production, in order to perform collaborative research according to the priorities of each country.

Typology of perceived family functioning in an American sample of patients with advanced cancer.

Schuler, Tammy A; Zaider, Talia I; Li, Yuelin; Hichenberg, Shira; Masterson, Melissa; Kissane, David W

2014-08-01

Poor family functioning affects psychosocial adjustment and the occurrence of morbidity following bereavement in the context of a family's coping with advanced cancer. Family functioning typologies assist with targeted family-centered assessment and intervention to offset these complications in the palliative care setting. Our objective was to identify the number and nature of potential types in an American palliative care patient sample. Data from patients with advanced cancer (N = 1809) screened for eligibility for a larger randomized clinical trial were used. Cluster analyses determined whether patients could be classified into clinically meaningful and coherent groups, based on similarities in their perceptions of family functioning across the cohesiveness, expressiveness, and conflict resolution subscales of the Family Relations Index. Patients' reports of perceived family functioning yielded a model containing five meaningful family types. Cohesiveness, expressiveness, and conflict resolution appear to be useful dimensions by which to classify patient perceptions of family functioning. "At risk" American families may include those we have called hostile, low-communicating, and less-involved. Such families may benefit from adjuvant family-centered psychosocial services, such as family therapy. Copyright © 2014 American Academy of Hospice and Palliative Medicine. Published by Elsevier Inc.

Perspectives of the mercosur parliament performance according to south american political organization

Directory of Open Access Journals (Sweden)

Clarissa Franzoi Dri

2007-04-01

Full Text Available The signature of the MERCOSUR Parliament Constitutive Protocol, in 2005, has opened new parliamentary perspectives to the integration process which takes place in the South Cone. The nomination “parliament”, the universal suffrage prevision and new legislative and control functions evidence possibilities for an outstanding actuation. But is it possible to consider that this new organ was created in the middle of political conditions favorable to an effective functionality? Looking for traces to an answer, the paper examines political and electoral characteristics common to the South American States. First, we study the daily relations between the Executive and Legislative Powers in South American presidential regimes. Then, we verify to what extent the proportional open-list electoral system, largely used in the election of the lower houses members in the continent, influences such relations. At the end, we discuss the new assembly perspectives of effectiveness based on the regional characteristics studied.

Electricity consumption and economic growth in seven South American countries

International Nuclear Information System (INIS)

Yoo, Seung-Hoon; Kwak, So-Yoon

2010-01-01

This paper attempts to investigate the causal relationship between electricity consumption and economic growth among seven South American countries, namely Argentina, Brazil, Chile, Columbia, Ecuador, Peru, and Venezuela using widely accepted time-series techniques for the period 1975-2006. The results indicate that the causal nexus between electricity consumption and economic growth varies across countries. There is a unidirectional, short-run causality from electricity consumption to real GDP for Argentina, Brazil, Chile, Columbia, and Ecuador. This means that an increase in electricity consumption directly affects economic growth in those countries. In Venezuela, there is a bidirectional causality between electricity consumption and economic growth. This implies that an increase in electricity consumption directly affects economic growth and that economic growth also stimulates further electricity consumption in that country. However, no causal relationships exist in Peru. The documented evidence from seven South American countries can provide useful information for each government with regard to energy and growth policy.

Family involvement is important in the recovery experience of culturally diverse adults with schizophrenia. However, little is known about the influence of family among consumers purported to have close family ties without regular contact. This study explored Asian American consumers' views about family relationships and participation in their recovery. Secondary analysis of qualitative data from a larger project was conducted to explore family related themes of 8 Asian Americans receiving services from recovery-focused programs in urban Southern California. Most consumers described their family support as adequate while simultaneously reporting limited family involvement. Asia-born and U.S.-born Asian consumers varied in describing family support, suggesting providers consider nativity in culturally responsive service delivery. Families need not be present to affect the perspectives of Asian Americans receiving recovery-oriented services. The extent of family influences on recovery, beyond the initial determination of current family contact, requires further exploration. (c) 2015 APA, all rights reserved).

White, Rebecca M B; Roosa, Mark W; Zeiders, Katharine H

2012-10-01

We present an integrated model for understanding Mexican American youth mental health within family, neighborhood, and cultural contexts. We combined two common perspectives on neighborhood effects to hypothesize that (a) parents' perceptions of neighborhood risk would negatively impact their children's mental health by disrupting key parenting and family processes, and (b) objective neighborhood risk would alter the effect parent and family processes had on youth mental health. We further incorporated a cultural perspective to hypothesize that an ethnic minority group's culture-specific values may support parents to successfully confront neighborhood risk. We provided a conservative test of the integrated model by simultaneously examining three parenting and family process variables: maternal warmth, maternal harsh parenting, and family cohesion. The hypothesized model was estimated prospectively in a diverse, community-based sample of Mexican American adolescents and their mothers (N = 749) living in the southwestern United States. Support for specific elements of the hypothesized model varied depending on the parenting or family process variable examined. For family cohesion results were consistent with the combined neighborhood perspectives. The effects of maternal warmth on youth mental health were altered by objective neighborhood risk. For harsh parenting, results were somewhat consistent with the cultural perspective. The value of the integrated model for research on the impacts of family, neighborhood, and cultural contexts on youth mental health are discussed, as are implications for preventive interventions for Mexican American families and youth.

Lee, Shiuyu Katie C; Knobf, M Tish

2016-12-01

To describe family involvement in decision making for primary treatment in Chinese-American women with early-stage breast cancer. Qualitative data were collected in 2003 from semi-structured questions in interviews with a sample of Chinese-American (ChA) women with breast cancer, who were recruited from the metropolitan New York area. Responses to the questions were written in Chinese immediately during the interview and read back to the subject for accuracy and validation. Content analysis was used to inductively code and analyze the data to generate themes. The participants consisted of 123 ChA women with early stage breast cancer with a mean age of 48.7 years (±9.3) and who had lived in the United States a median of 13.6 years. Support and Caring was the major theme that described family involvement in the breast cancer decision-making process. Gathering Information, Being There, Navigating the Health Care System, Maintaining Family Life and Making the Decision described the aspects of family support in the process. The majority of women described the treatment decision making as a collaborative supportive process with the family, but limited English fluency, strong opinions, lack of a shared perspective, distant living proximity and competing work responsibilities of family members were stressful for the women and perceived as non-supportive. Family involvement in health care decision making is culturally embedded in Asian populations. Culturally sensitive patient and family consultation strategies are needed to assist informed treatment decision making in Chinese-American women diagnosed with breast cancer.

Parenting styles and child behavior in African American families of preschool children.

Science.gov (United States)

Querido, Jane G; Warner, Tamara D; Eyberg, Sheila M

2002-06-01

Examined the relations between parenting styles and child behavior problems in African American preschool children. Participants were 108 African American female caregivers of 3- to 6-year-old children. Correlational analysis showed that parent-reported child behavior problems were associated with maternal education, family income, and parents' endorsement of authoritative parenting, authoritarian parenting, and permissive parenting. Hierarchical regression analysis showed that the authoritative parenting style was most predictive of fewer child behavior problems. These results are consistent with previous findings with European American families and provide strong support for the cross-cultural validity of the authoritative parenting style.

Bahrassa, Nazneen F; Syed, Moin; Su, Jenny; Lee, Richard M

2011-10-01

This three-study investigation examined risk and protective factors for poor academic performance among Asian American first-year undergraduates. Students were surveyed prior to starting college and their GPA was collected after their first semester in college. Family conflict as a significant risk factor for poor academic performance was examined in all three studies. The results indicate that higher family conflict prior to college was related to lower first-semester college GPA, after controlling for standardized test scores and high school rank (Studies 1-3). Even though psychological distress was related to both family conflict and GPA, it did not mediate the relationship between family conflict and GPA (Studies 2 and 3). In terms of protective factors, the results indicate that life satisfaction buffered the negative effects of family conflict on first-semester college GPA (Study 3). Together, these findings support the need to take into account family variables and psychological well-being in the academic performance of Asian American students as they transition from high school to college.

Ocean-atmosphere forcing of South American tropical paleoclimate, LGM to present

Baker, P. A.; Fritz, S. C.; Dwyer, G. S.; Rigsby, C. A.; Silva, C. G.; Burns, S. J.

Because of many recent terrestrial paleoclimatic and marine paleoceanographic records, late Quaternary South American tropical paleoclimate is as well understood as that anywhere in the world. While lessons learned from the recent instrumental record of climate are informative, this record is too short to capture much of the lower frequency variability encountered in the paleoclimate records and much of the observed paleoclimate is without modern analogue. This paleoclimate is known to be regionally variable with significant differences both north and south of the equator and between the western high Andes and eastern lowlands of the Amazon and Nordeste Brazil. Various extrinsic forcing mechanisms affected climate throughout the period, including global concentrations of GHGs, Northern Hemisphere ice sheet forcing, seasonal insolation forcing of the South American summer monsoon (SASM), millennial-scale Atlantic forcing, and Pacific forcing of the large-scale Walker circulation. The magnitude of the climate response to these forcings varied temporally, largely because of the varying amplitude of the forcing itself. For example, during the last glacial, large-amplitude north Atlantic forcing during Heinrich 1 and the LGM itself, led to wet (dry) conditions south (north) of the equator. During the Holocene, Atlantic forcing was lower amplitude, thus seasonal insolation forcing generally predominated with a weaker-than-normal SASM during the early Holocene resulting in dry conditions in the south-western tropics and wet conditions in the eastern lowlands and Nordeste; in the late Holocene seasonal insolation reached a maximum in the southern tropics and climate conditions reversed.

Public Policy and Extended Families: Evidence from South Africa

OpenAIRE

2000-01-01

Tightly knit extended families, in which people often give money to and get money from relatives, characterize many developing countries. These intra-family flows mean that public policies may affect a very different group of people than the one they target. To assess the empirical importance of these effects, we study a cash pension program in South Africa that targets the elderly. Focusing on three-generation households , we use the variation in pension receipt that comes from differences i...

The relationship between the evolution of genes and languages has been studied for over three decades. These studies rely on the assumption that languages, as many other cultural traits, evolve in a gene-like manner, accumulating heritable diversity through time and being subjected to evolutionary mechanisms of change. In the present work we used genetic data to evaluate South American linguistic classifications. We compared discordant models of language classifications to the current Native American genome-wide variation using realistic demographic models analyzed under an Approximate Bayesian Computation (ABC) framework. Data on 381 STRs spread along the autosomes were gathered from the literature for populations representing the five main South Amerindian linguistic groups: Andean, Arawakan, Chibchan-Paezan, Macro-Jê, and Tupí. The results indicated a higher posterior probability for the classification proposed by J.H. Greenberg in 1987, although L. Campbell's 1997 classification cannot be ruled out. Based on Greenberg's classification, it was possible to date the time of Tupí-Arawakan divergence (2.8 kya), and the time of emergence of the structure between present day major language groups in South America (3.1 kya).

Cretaceous to Recent Asymetrical Subsidence of South American and West African Conjugate Margins

Science.gov (United States)

Kenning, J.; Mann, P.

2017-12-01

Two divergent interpretations have been proposed for South American rifted-passive margins: the "mirror hypothesis" proposes that the rifted margins form symmetrically from pure shear of the lithosphere while upper-plate-lower plate models propose that the rifted margins form asymmetrically by simple shear. Models based on seismic reflection and refraction imaging and comparison of conjugate, rifted margins generally invoke a hybrid stretching process involving elements of both end member processes along with the effects of mantle plumes active during the rift and passive margin phases. We use subsidence histories of 14, 1-7 km-deep exploration wells located on South American and West African conjugate pairs now separated by the South Atlantic Ocean, applying long-term subsidence to reveal the symmetry or asymmetry of the underlying, conjugate, rift processes. Conjugate pairs characterize the rifted margin over a distance of 3500 km and include: Colorado-South Orange, Punta Del Este-North Orange, South Pelotas-Lüderitz and the North Pelotas-Walvis Basins. Of the four conjugate pairs, more rapid subsidence on the South American plate is consistently observed with greater initial rift and syn-rift subsidence rates of >60m/Ma (compared to 100 m/Ma are observed offshore South Africa between approximately 120-80 Ma, compatible with onset of the post-rift thermal sag phase. During this period the majority of burial is completed and rates remain low at Argentina/Uruguay displays more gradual subsidence throughout the Cretaceous, consistently averaging a moderate 15-30m/Ma. By the end of this stage there is a subsequent increase to 25-60 m/Ma within the last 20 Ma, interpreted to reflect lithospheric loading due to increased sedimentation rates during the Cenozoic. This increase in subsidence rate is not seen in the African conjugate section where the majority of sediments bypassed the highly aggraded Cretaceous shelf. Initially greater on the Brazilian margin compared to

Daily and seasonal activity patterns of free range South-American rattlesnake (Crotalus durissus).

Science.gov (United States)

Tozetti, Alexandro M; Martins, Marcio

2013-09-01

This study aimed at describing daily and seasonal variation in the activity of a population of South-American rattlesnakes (Crotalus durissus) in a savanna like habitat (Cerrado) in Southeastern Brazil. Seasonal and daily activities of snakes were evaluated by the number of captures of snakes during road surveys, accidental encounters, and relocations by radio-tracking. Our results show that climatic variables such as air temperature and rainfall have little influence on the activity pattern of rattlesnakes. Our findings indicate that rattlesnakes spend most of the day resting and most of the night in ambush posture. The South-American rattlesnake is active throughout the year with a discrete peak in activity of males during the matting season. The possibility of maintaining activity levels even during the coldest and driest season can facilitate the colonization of several habitats in South America. This possibility currently facilitates the colonization of deforested areas by rattlesnakes.

Acculturative family distancing (AFD) and depression in Chinese American families.

Science.gov (United States)

Hwang, Wei-Chin; Wood, Jeffrey J; Fujimoto, Ken

2010-10-01

Knowledge of acculturative processes and their impact on immigrant families remains quite limited. Acculturative family distancing (AFD) is the distancing that occurs between immigrant parents and their children and is caused by breakdowns in communication and cultural value differences. It is a more proximal and problem-focused formulation of the acculturation gap and is hypothesized to increase depression via family conflict. Data were collected from 105 Chinese American high school students and their mothers. Rasch modeling was used to refine the AFD measure, and structural equation modeling was used to determine the effects of AFD on youth and maternal depression. Findings indicate that greater AFD was associated with higher depressive symptoms and risk for clinical depression. Family conflict partially mediated this relation for youths, whereas for mothers, AFD directly increased risk for depression. Greater mother-child heritage enculturation discrepancies were associated with greater mother and child AFD. Mainstream acculturation discrepancies and language gaps between mothers and youths were not significantly associated with any of the primary outcome variables. Results highlight the need for better understanding of how AFD and other acculturation-gap phenomena affect immigrant mental health. They also underscore the need for prevention and intervention programs that target communication difficulties and intergenerational cultural value differences.

The politics of Latin American family-planning policy.

Science.gov (United States)

Weaver, J L

1978-07-01

In population planning in Latin America the programs are as successful as the government's support of family planning. Colombia is one of the few Latin American countries which has actively exhorted its populace to birth control. If the propensity for large families reflects a belief in the economic or social utility of children, instead of machismo, birthrates will fall with expanded social security and economic welfare programs. If birthrates are the result of machismo, new gender models stressing the positive rewards and social esteem to be gained through responsible parenthood would have to be taught to both adults and children. The position profamily planning in most Latin American countries is generally supported by the ministers, technocrats, corporations, businessmen, middle-class women, doctors, mass media, protestant congregations, and working-class women. Family planning is usually opposed by members of the armed forces, Catholic hierarchy, Catholic lay organizations, oligarchy, university students, leftist intellectuals, Marxist insurgents, Indian communities, and peasants. The portion of the total national populations encompassed by the groups composing the core combination, ideological bias, and stability group ranges from 50-60% in Argentina, Uruguay, and Venezuela to 10-20% in Central America, Bolivia, Ecuador, and Paraguay. Most groups are outside the policy-making process.

Family Violence and Child Sexual Abuse Among South Asians in the US.

Robertson, Hillary A; Chaudhary Nagaraj, Nitasha; Vyas, Amita N

2016-08-01

Family violence, including child sexual abuse (CSA), is a significant public health problem in the United States. It is particularly difficult to assess family violence and CSA among South Asians because it is often hidden due to cultural and familial stigma. A web-based survey was administered to a convenience sample (n = 368) of South Asian adults in the US. One-fourth (25.2 %) of the sample reported CSA; 13.8 % reported abuse involving exposure; 21.5 % reported abuse involving touching; 4.5 % reported attempted sexual intercourse; and 3.5 % reported forced sexual intercourse. Adjusted odds ratios found that participants who reported any relationship violence were significantly more likely to have experienced CSA (OR 2.28; 95 % CI 1.26-4.13); and suicide attempt was significantly associated with CSA (OR 3.96; 95 % CI 1.27-12.3). The findings presented in this formative study will assist in guiding future studies and interventions for South Asians in the United States.

The relationship between shame and perceived biological origins of mental illness among South Asian and white American young adults.

Science.gov (United States)

Mokkarala, Sameera; O'Brien, Erin Keely; Siegel, Jason T

2016-06-01

Mental illness (MI) affects one in four people in their lifetime and a failure to seek help for MI can have grave consequences. To decrease stigma and increase help seeking, prior campaigns have promoted the biological origins of MI. Even though some research supports the efficacy of this approach, other research does not. We propose cultural differences as a partial explanation for these inconsistent results. The current study assessed ethnic differences in the relationship between perceived causes of MI, shame associated with MI and perceived family support for help seeking. White and South Asian American (SAA) undergraduate students completed an online survey (n = 177). Results indicated that SAAs were significantly more likely than whites to perceive character deficits as the cause of MI. Further, among those who had sought help for MI, ethnic differences emerged in perceptions of MI based on perceived cause. SAAs who believed that MI had biological origins perceived more shame and less family support for seeking help compared to SAAs who believed MI was due to character deficits. The converse was true for whites - those who believed that MI had biological origins perceived less shame and more family support for help seeking compared to whites who believed MI was due to character deficits. The results of the current study illuminate the role that culture plays in perceptions of MI. Further, these results have implications for interventions targeting South Asian populations and for mental health outreach in general.

Values expressed through intergenerational family food and nutrition management systems among African American women.

Ahye, Brenda A; Devine, Carol M; Odoms-Young, Angela M

2006-01-01

This grounded theory investigation aimed to understand intergenerational family roles and the food management strategies of African American women from a social-ecological perspective. Thirty women from 10 low/moderate-income 3-generation urban families participated in interviews covering roles, health, nutrition, and food management strategies. Four dynamic family systems for managing food and nutrition emerged from qualitative data analysis. Participants expressed values of responsibility, social connections, caretaking, reward, and equal opportunity, and fulfilling responsibilities for family care, connections, and finances. These values and systems provide a basis for culturally appropriate, interpersonal-level nutrition interventions among African American women that build on family structures, needs, and resources.

Alcohol use among Asian American adolescent girls: the impact of immigrant generation status and family relationships.

Science.gov (United States)

Fang, Lin; Schinke, Steven P

2011-01-01

Underage drinking among Asian American adolescent girls is not well understood. Based on family interaction theory, the study examined the interrelationships among acculturation variables, family relationships, girls' depressed mood, peer alcohol use, and girls' alcohol use in a sample of 130 Asian American mother-daughter dyads. The mediating role of family relationships, girls' depressed mood, and peer alcohol use on girls' drinking was also assessed. The study advances knowledge related to alcohol use among early Asian American adolescent girls, highlights the effect of immigrant generation status and family relationships, and has implications for culturally specific underage drinking prevention programs.

Barr-Anderson, D J; Adams-Wynn, A W; DiSantis, K I; Kumanyika, S

2013-01-01

Obesity interventions that involve family members may be effective with racial/ethnic minority youth. This review assessed the nature and effectiveness of family involvement in obesity interventions among African-American girls aged 5-18 years, a population group with high rates of obesity. Twenty-six databases were searched between January 2011 and March 2012, yielding 27 obesity pilot or full-length prevention or treatment studies with some degree of family involvement and data specific to African-American girls. Interventions varied in type and level of family involvement, cultural adaptation, delivery format and behaviour change intervention strategies; most targeted parent-child dyads. Some similarities in approach based on family involvement were identified. The use of theoretical perspectives specific to African-American family dynamics was absent. Across all studies, effects on weight-related behaviours were generally promising but often non-significant. Similar conclusions were drawn for weight-related outcomes among the full-length randomized controlled trials. Many strategies appeared promising on face value, but available data did not permit inferences about whether or how best to involve family members in obesity prevention and treatment interventions with African-American girls. Study designs that directly compare different types and levels of family involvement and incorporate relevant theoretical elements may be an important next step. © 2012 The Authors. obesity reviews © 2012 International Association for the Study of Obesity.

Agathis is an iconic genus of large, ecologically important, and economically valuable conifers that range over lowland to upper montane rainforests from New Zealand to Sumatra. Exploitation of its timber and copal has greatly reduced the genus's numbers. The early fossil record of Agathis comes entirely from Australia, often presumed to be its area of origin. Agathis has no previous record from South America. We describe abundant macrofossils of Agathis vegetative and reproductive organs, from early and middle Eocene rainforest paleofloras of Patagonia, Argentina. The leaves were formerly assigned to the New World cycad genus Zamia. Agathis zamunerae sp. nov. is the first South American occurrence and the most complete representation of Agathis in the fossil record. Its morphological features are fully consistent with the living genus. The most similar living species is A. lenticula, endemic to lower montane rainforests of northern Borneo. Agathis zamunerae sp. nov. demonstrates the presence of modern-aspect Agathis by 52.2 mya and vastly increases the early range and possible areas of origin of the genus. The revision from Zamia breaks another link between the Eocene and living floras of South America. Agathis was a dominant, keystone element of the Patagonian Eocene floras, alongside numerous other plant taxa that still associate with it in Australasia and Southeast Asia. Agathis extinction in South America was an integral part of the transformation of Patagonian biomes over millions of years, but the living species are disappearing from their ranges at a far greater rate.

Mandara, Jelani; Rogers, Sheba Y.; Zinbarg, Richard E.

2011-01-01

The relationship between family structure and marijuana use throughout adolescence was assessed among 1,069 African Americans from the NLSY. A model was also tested suggesting that the effects of family structure on marijuana use would be mediated by poverty, neighborhood quality, and adolescents' self-control. As most prior studies have found,…

To identify barriers to and facilitators of older South Asian Indian-Americans' (SAIAs') engagement in behaviors associated with advance care planning (ACP). Using a descriptive qualitative design guided by the transcultural nursing assessment model, data were collected in focus groups of community-dwelling older SAIA participants, SAIA family caregivers, and SAIA physicians. A directed approach using predetermined coding categories derived from the Transcultural Nursing Assessment model and aided by NVivo 10 software (Melbourne, Australia) facilitated the qualitative data analysis. Eleven focus groups with 36 older SAIAs (61% female, 83% 70+ years old), 10 SAIA family caregivers, and 4 SAIA physicians indicated prior lack of awareness of ACP, good health status, lack of access to linguistically and health literacy-tailored materials, healthcare provider hesitation to initiate discussions on ACP, trust in healthcare providers' or oldest sons' decision making, busy family caregiver work routines, and cultural assumptions about filial piety and after-death rituals as major barriers to engaging in ACP. Introducing ACP using personal anecdotes in a neutral, group-based community setting and incentivizing ACP discussions by including long-term care planning were suggested as facilitators to engage in ACP. The study's findings will guide development of culturally sensitive interventions to raise awareness about ACP among SAIAs and encourage SAIA older adults to engage in ACP. © 2017 Sigma Theta Tau International.

A Qualitative Study of the Long Term Impact of Welfare Reform on Cambodian American Families

Directory of Open Access Journals (Sweden)

Karen Quintiliani

2014-01-01

Full Text Available Many Cambodian American families have struggled on the economic margins since their arrival to the U.S. in the 1980s. To raise families in poverty Cambodians created family survival strategies to buffer themselves against economic uncertainty and the vagaries of the social welfare system. They combine public assistance with formal and informal work activities of household members, including teenagers and young adults, to survive. With the passage of the Personal Responsibility and Work Opportunity Act of 1996 or Welfare Reform, Cambodians lost vital economic resources. Based upon a longitudinal qualitative study from 1998-2007, this article looks back on how first generation Cambodian American household members adjusted to changes in welfare policy practices and how the loss of vital resources impacted the youth (15-19 years old coming of age in these families. The research findings and family case histories presented in this article illustrate the shared struggle of Cambodian family members in poverty. It reveals the significant challenges second generation Cambodian Americans face to achieve higher education goals when welfare policies systematically undercut family survival strategies.

Development of an empirical typology of African American family functioning.

Science.gov (United States)

Mandara, Jelani; Murray, Carolyn B

2002-09-01

This study empirically identified types of African American families. Adolescents (N = 111) were assessed on family functioning. With cluster analytic methods, 3 types of families were identified. The cohesive-authoritative type was above average on parental education and income, averaged about 2 children, exhibited a high quality of family functioning and high self-esteem in adolescents. The conflictive-authoritarian type had average parental education and income, an average of 2.7 children, exhibited controlling and rigid discipline, and placed a high emphasis on achievement. The defensive-neglectful type was predominately headed by single mothers with below average education and income and averaged about 3 children. Such families displayed chaotic family processes, and adolescents tended to suffer from low self-esteem. The typology exhibited good reliability. The implications of the typology are discussed.

Full Text Available In this document, the Inter-American Committee of Cardiovascular Prevention and Rehabilitation, together with the South American Society of Cardiology, aimed to formulate strategies, measures, and actions for cardiovascular disease prevention and rehabilitation (CVDPR. In the context of the implementation of a regional and national health policy in Latin American countries, the goal is to promote cardiovascular health and thereby decrease morbidity and mortality. The study group on Cardiopulmonary and Metabolic Rehabilitation from the Department of Exercise, Ergometry, and Cardiovascular Rehabilitation of the Brazilian Society of Cardiology has created a committee of experts to review the Portuguese version of the guideline and adapt it to the national reality. The mission of this document is to help health professionals to adopt effective measures of CVDPR in the routine clinical practice. The publication of this document and its broad implementation will contribute to the goal of the World Health Organization (WHO, which is the reduction of worldwide cardiovascular mortality by 25% until 2025. The study group's priorities are the following: • Emphasize the important role of CVDPR as an instrument of secondary prevention with significant impact on cardiovascular morbidity and mortality; • Join efforts for the knowledge on CVDPR, its dissemination, and adoption in most cardiovascular centers and institutes in South America, prioritizing the adoption of cardiovascular prevention methods that are comprehensive, practical, simple and which have a good cost/benefit ratio; • Improve the education of health professionals and patients with education programs on the importance of CVDPR services, which are directly targeted at the health system, clinical staff, patients, and community leaders, with the aim of decreasing the barriers to CVDPR implementation.

McHale, Susan M; Whiteman, Shawn D; Kim, Ji-Yeon; Crouter, Ann C

2007-06-01

The authors studied sibling relationships of African American youths and family and youth characteristics linked to sibling dynamics. Participants were fathers, mothers, and 2 siblings (M = 14.04 and M = 10.34 years of age) from 172 working-middle class 2-parent families. Cluster analyses of data collected in home interviews revealed 3 sibling relationship types: positive, negative, and distant. Parent education was lower, parent religiosity higher, and parent-child relationships more positive in the positive group; maternal discrimination experiences were higher in the negative group; youth ethnic identity was stronger in the positive group; and youth depression and risky behavior were higher in the negative group. The findings target sociocultural factors to consider in interventions for African American families.

2012-06-01

A major challenge facing contemporary cancer educators is how to optimize the dissemination of breast cancer prevention and control information to African American women in the Deep South who are believed to be cancer free. The purpose of this research was to provide insight into the breast cancer information-acquisition experiences of African American women in Alabama and Mississippi and to make recommendations on ways to better reach members of this high-risk, underserved population. Focus group methodology was used in a repeated, cross-sectional research design with 64 African American women, 35 years old or older who lived in one of four urban or rural counties in Alabama and Mississippi. Axial-coded themes emerged around sources of cancer information, patterns of information acquisition, characteristics of preferred sources, and characteristics of least-preferred sources. It is important to invest in lay health educators to optimize the dissemination of breast cancer information to African American women who are believed to be cancer free in the Deep South.

Family Economic Stress, Quality of Paternal Relationship, and Depressive Symptoms among African American Adolescent Fathers

Science.gov (United States)

Hunt, Tenah K. A.; Caldwell, Cleopatra H.; Assari, Shervin

2015-01-01

This study examined the association between perceived family economic stress, quality of father-son relationships, and depressive symptoms among African American adolescent fathers. Data were collected during pregnancy from 65 African American adolescents who were first-time fathers, ages 14-19. Results from multiple regression analyses indicated that higher paternal relationship satisfaction was associated with fewer depressive symptoms among adolescent fathers. Additionally, depressive symptoms were higher among adolescent fathers who reported experiencing higher levels of conflict with their fathers. Further, paternal conflict moderated the effect of perceived family economic stress on depressive symptoms. That is, among adolescent fathers experiencing low levels of conflict with their fathers, high perceived family economic stress was associated with more depressive symptoms. Study findings suggest that the risk for depressive symptoms is highest among adolescent fathers experiencing low family economic stress and highly conflictual relations with their fathers. These results highlight the complexities of paternal relationships and perceived economic stressors on depressive symptoms during pregnancy for African American adolescent fathers. The importance of expanding research on influential familial relationships and economic stressors on adolescent African American fathers is discussed. PMID:26617454

Cultural Adaptation, Parenting and Child Mental Health Among English Speaking Asian American Immigrant Families.

Huang, Keng-Yen; Calzada, Esther; Cheng, Sabrina; Barajas-Gonzalez, R Gabriela; Brotman, Laurie Miller

2017-08-01

Contrary to the "model minority" myth, Asian American children, especially those from low-income immigrant families, are at risk for both behavioral and emotional problems early in life. Little is known, however, about the underlying developmental mechanisms placing Asian American children at risk, including the role of cultural adaptation and parenting. This study examined cultural adaptation, parenting practices and culture related parenting values and child mental health in a sample of 157 English speaking Asian American immigrant families of children enrolled in early childhood education programs in low-income, urban neighborhoods. Overall, cultural adaptation and parenting cultural values and behaviors were related to aspects of child mental health in meaningful ways. Parents' cultural value of independence appears to be especially salient (e.g., negatively related to behavior problems and positively related to adaptive behavior) and significantly mediates the link between cultural adaptation and adaptive behavior. Study findings have implications for supporting Asian American immigrant families to promote their young children's mental health.

A proof of concept study to assess the potential of PCR testing to detect natural Mycobacterium bovis infection in South American camelids.

Crawshaw, Timothy R; Chanter, Jeremy I; McGoldrick, Adrian; Line, Kirsty

2014-02-07

Cases of Mycobacterium bovis infection South American camelids have been increasing in Great Britain. Current antemortem immunological tests have some limitations. Cases at post mortem examination frequently show extensive pathology. The feasibility of detecting Mycobacterium bovis DNA in clinical samples was investigated. A sensitive extraction methodology was developed and used on nasal swabs and faeces taken post-mortem to assess the potential for a PCR test to detect Mycobacterium bovis in clinical samples. The gross pathology of the studied South American camelids was scored and a significantly greater proportion of South American camelids with more severe pathology were positive in both the nasal swab and faecal PCR tests. A combination of the nasal swab and faecal PCR tests detected 63.9% of all the South American camelids with pathology that were tested. The results suggest that antemortem diagnosis of Mycobacterium bovis in South American camelids may be possible using a PCR test on clinical samples, however more work is required to determine sensitivity and specificity, and the practicalities of applying the test in the field.

Taxonomic revision of the South American catfish genus Ageneiosus (Siluriformes: Auchenipteridae) with the description of four new species

Ribeiro, Frank R.V.; Rapp Py-Daniel, Lúcia H.; Walsh, Stephen J.

2017-01-01

The catfish genus Ageneiosus in the exclusively Neotropical family Auchenipteridae is revised. Species of Ageneiosus are widely distributed in all major South American continental drainages except the São Francisco River basin and small rivers along the Brazilian east coast. The taxonomic revision was based on examination of available type specimens, additional museum material and comparisons of original descriptions. A suite of morphometric, meristic and qualitative characters of internal and external anatomy were used to diagnose valid species and determine synonyms. Thirteen valid species are recognized in the genus Ageneiosus, some of which are widely distributed across South America. Ageneiosus pardalis is the only trans-Andean species in the genus. Ageneiosus polystictus and Ageneiosus uranophthalmus are more widely distributed than previously reported. Ageneiosus marmoratus is a junior synonym of Ageneiosus inermis. Ageneiosus dentatus is a valid species and its name is removed from the synonymy of Ageneiosus ucayalensis. Four new species are described: Ageneiosus akamai, Ageneiosus apiaka, Ageneiosus intrusus and Ageneiosus lineatus, all from the Amazon River basin. A dichotomous key for all 13 valid species of Ageneiosus species is provided.

Evaluation of insulin resistance in two kinds of South American camelids: llamas and alpacas.

Araya, A V; Atwater, I; Navia, M A; Jeffs, S

2000-10-01

Insulin resistance was evaluated in South American camelids, llamas and alpacas, by use of the minimal model test and the insulin tolerance test. Animals were catheterized for long-term studies and tamed to minimize stress during evaluation. Results indicated a low insulin sensitivity index (SI) = 0 to 0.97, median = 0.39 x 10(-4) min/uIU x ml, about a fifth the value in other mammals and humans. The KITT was between 1.43 and 3.19 %/min, also significantly lower than that reported for humans. Glycosylated hemoglobin concentration was 6%, and HbAlc concentration was 5.5%; red blood cell lifetime, as measured by use of the 51Cr method, was 120 days, similar to the value in humans. We concluded that llamas and alpacas have naturally higher blood glucose concentration than do humans and other mammals during the glucose tolerance test. Using the same mathematical tools to evaluate glucose metabolism as those used in people, South American camelids appear to be resistant to insulin. Thus, the South American camelid may be a useful new animal model for the study of sugar metabolism and various facets of diabetes mellitus, especially protection from the deleterious effects of glycosylation.

American families: trends and correlates.

Davanzo, J; Rahman, M O

1993-01-01

Discussion focused on the nature of the roles of the family, a review of the major demographic changes (marriage, cohabitation, nonfamily households, remarriage, fertility, teenage pregnancy, and female employment) affecting the American family in the past decades, and the nature of the impact on women, men, and children. There were four major trends identified: 1) increased proportions of children living in single-parent families due to high rates of divorce and increased childbearing outside of marriage; 2) increased proportions of adults in nontraditional living arrangements; 3) increased female labor force participation during all stages of the life cycle; and 4) decreased proportions of children and increased proportions of older people out of total population due to declining mortality and fertility rates. Family formation arises out of childbearing and childrearing roles, the need for companionship and emotional support, and the opportunities for specialization and trade, and the economies of scale. The costs of family living may include the potential for disagreement, conflict, loss of privacy, and time and money. There were a number of reasons identified for not maintaining traditional families consisting of a married couple with children. The trends were for later age at marriage: 24.4 years in 1992 for women, increased cohabitation (almost 50% cohabiting prior to first marriage in 1985-86), decreased number of married couple households, and increased number of adults in non-family households. The divorce rate has risen over the past 100 years with peaks in the 1970s; the reasons were identified as increased baby boomers and new marriages, increased labor participation of women, and changes in gender roles. The stabilization and slight decline in rates may be due to a natural leveling, the likelihood of greater stability within new marriages, and the aging of the baby boomers. An anticipated increase in divorce rates in the future was also justified

Full Text Available R Jeanne Ruiz,1 Rita H Pickler,2 C Nathan Marti,3 Nancy Jallo41College of Nursing, The Ohio State University, Columbus, OH, USA; 2Department of Patient Services, Cincinnati Children's Hospital Medical Center, Cincinnati, OH, USA; 3Abacist Analytics, Austin, TX, USA; 4School of Nursing, Virginia Commonwealth University, Richmond, VA, USAObjective: To examine the potential moderating effects of family cohesion and acculturation on the physiological stress response (cortisol as a predictor of preterm birth (PTB in pregnant Mexican-American women.Methods: The sample included 470 participants; 33 had preterm births. All participants were self-identified as Mexican-American. In this cross-sectional study, family cohesion was measured by a self-report questionnaire. Acculturation was measured by self-report questionnaire as well as by years in the United States and country of birth. Stress was measured by serum cortisol. All measures were obtained at 22—24 weeks gestation. Additional data including history of PTB were obtained from the health record. Data analysis was primarily conducted using logistic regression.Results: The relationship between stress and PTB was predicted by family cohesion (estimate/standard error [E/SE] = —2.46, P = 0.014 and acculturation (E/SE = 2.56, P = 0.011. In addition, there was an interaction between family cohesion and history of previous PTB (E/SE = —2.12, P = 0.035.Conclusion: Results indicate that the impact of cortisol on PTB is predicted by acculturation and family cohesion such that higher levels of cortisol in conjunction with higher levels of acculturation and lower levels of family cohesion are associated with increased risk of PTB. In addition, low family cohesion in combination with a history of PTB was associated with higher levels of PTB. Assessment of family cohesion, including problem solving, adherence to family decisions, family shared space, and activity, should be included as part of prenatal

The context of collecting family health history: examining definitions of family and family communication about health among African American women.

Public health initiatives encourage the public to discuss and record family health history information, which can inform prevention and screening for a variety of conditions. Most research on family health history discussion and collection, however, has predominantly involved White participants and has not considered lay definitions of family or family communication patterns about health. This qualitative study of 32 African American women-16 with a history of cancer-analyzed participants' definitions of family, family communication about health, and collection of family health history information. Family was defined by biological relatedness, social ties, interactions, and proximity. Several participants noted using different definitions of family for different purposes (e.g., biomedical vs. social). Health discussions took place between and within generations and were influenced by structural relationships (e.g., sister) and characteristics of family members (e.g., trustworthiness). Participants described managing tensions between sharing health information and protecting privacy, especially related to generational differences in sharing information, fear of familial conflict or gossip, and denial (sometimes described as refusal to "own" or "claim" a disease). Few participants reported that anyone in their family kept formal family health history records. Results suggest family health history initiatives should address family tensions and communication patterns that affect discussion and collection of family health history information.

Renshaw, Michelle

2009-01-01

Today, patients' families in the West are regaining the access to hospitals that they lost when hospitals emerged as the primary site for medical treatment, research and training at the beginning of the twentieth century. In China, however, families were never excluded from American mission-run hospitals, in fact, they were indispensable. Families were in the waiting rooms, consulting rooms,wards and operating theatres. They provided more than reassurance and comfort: they fed and nursed their sick relatives, acted as advocates and middlemen and may even have lowered the incidence of cross-infection, the scourge of the contemporary hospital in the West.

Intestinal helminths in lowland South American Indians: some evolutionary interpretations.

Confalonieri, U; Ferreira, L F; Araújo, A

1991-12-01

Data on intestinal parasite infections for South American Indians in prehistoric times as revealed by coprolite analysis are being used to support transoceanic migration routes from the Old World to the New World. These same findings on modern semi-isolated aborigines, considered persisting prehistoric patterns, are also of great importance as indicators of pre-Columbian peopling of South America. This is the case for the Lengua Indians from Paraguay, studied in the 1920s, and the Yanomami and the Salumã from Brazil, studied in the 1980s. The intestinal parasitic profile of these groups can be empirically associated with culture change, but no clear correlations with the population biology of their hosts can be made at present because of scarcity of data.

The Experience of Paid Family-Care Workers of People with Dementia in South Korea

Jungmin Kim, RN, MN

2018-03-01

Full Text Available Purpose: The South Korean government introduced the universal long-term care insurance program in 2008 that created a new employment category of “paid family-care worker” to assist the elderly with chronic illnesses including dementia. The aim of this study was to understand the lived experience of paid family-care workers of people with dementia in South Korea. Methods: The study was a qualitative research design underpinned by interpretive description principles involving eight paid family-care workers. The participants were recruited by attaching the advertisement flyer in a notice board of an educational facility for paid family-care workers. Results: Paid family-care workers struggled to manage the behavioral and psychological symptoms of their care recipients. Their workloads created physical, emotional, social, and financial burdens. However, the care-giving activities were encouraged through their sense of responsibility, filial piety, and personal religious beliefs. Financial subsidies from the government and help received from others were also identified as encouragements. The education course provided to them assisted them to improve their dementia-care capabilities. Conclusion: Understanding paid family-care workers' lived experience in dementia care in South Korea assists with the identification of their educational needs and level of support they require to improve dementia care in the home care environment. A number of suggestions are made to increase paid family-care workers' knowledge, clinical skills, and job satisfaction to reduce their burdens and work-related incidents, such as challenging behaviors from those being cared for.

Perceived work and family conflict among African American nurses in college.

Science.gov (United States)

Gipson-Jones, Trina

2009-07-01

This article describes the perceptions of African American nurses regarding the interaction between work-family conflict, job satisfaction, and psychological well-being. A qualitative descriptive design was employed to conduct six focus group sessions with 23 nurses at three universities in the southeastern United States. Stressors such as racism or lack of teamwork and supervisor support caused the nurses to contemplate leaving a workplace or the profession. Family stressors, such as an ill family member, also influenced any decision regarding career longevity. Future studies examining work-family interface, especially positive spillover and psychological well-being are warranted.

A new cryptic species of South American freshwater pufferfish of the genus Colomesus (Tetraodontidae, based on both morphology and DNA data.

Directory of Open Access Journals (Sweden)

Cesar R L Amaral

Full Text Available The Tetraodontidae are an Acantomorpha fish family with circumglobal distribution composed of 189 species grouped in 19 genera, occurring in seas, estuaries, and rivers between the tropical and temperate regions. Of these, the genus Colomesus is confined to South America, with what have been up to now considered only two species. C. asellus is spread over the entire Amazon, Tocantins-Araguaia drainages, and coastal environments from the Amazon mouth to Venezuela, and is the only freshwater puffers on that continent. C. psittacus is found in coastal marine and brackish water environments from Cuba to the northern coast of South America as far south as to Sergipe in Brazil. In the present contribution we used morphological data along with molecular systematics techniques to investigate the phylogeny and phylogeography of the freshwater pufferfishes of the genus Colomesus. The molecular part is based on a cytochrome C oxidase subunit I dataset constructed from both previously published and newly determined sequences, obtained from specimens collected from three distinct localities in South America. Our results from both molecular and morphological approaches enable us to identify and describe a new Colomesus species from the Tocantins River. We also discuss aspects of the historical biogeography and phylogeography of the South American freshwater pufferfishes, suggesting that it could be more recent than previously expected.

We do so through analyses of clade diversification, ecomorphology and guild structure in the Sparassodonta, metatherians that were the predominant mammalian carnivores of pre-Pleistocene South America. Body mass and 16 characters of the dentition are used to quantify morphological diversity (disparity) in sparassodonts and to compare them to extant marsupial and placental carnivores and extinct North American carnivoramorphans. We also compare trophic diversity of the Early Miocene terrestrial carnivore guild of Santa Cruz, Argentina to that of 14 modern and fossil guilds from other continents. We find that sparassodonts had comparatively low ecomorphological disparity throughout their history and that South American carnivore palaeoguilds, as represented by that of Santa Cruz, Argentina, were unlike modern or fossil carnivore guilds of other continents in their lack of mesocarnivores and hypocarnivores. Our results add to a growing body of evidence highlighting non-analogue aspects of extinct South American mammals and illustrate the dramatic effects that historical contingency can have on the evolution of mammalian palaeocommunities.

The tectonic setting of the Caribbean region and the K/T turnover of the South American land-mammal fauna

Energy Technology Data Exchange (ETDEWEB)

Ortiz-Jaureguizar, E.; Pascual, R.

2011-07-01

According to the fossil record, a biotic interchange of land vertebrates (e.g. booid snakes, dinosaurs and mammals) occurred between the Americas during the Late Cretaceous-Early Palaeocene. The arrival of North American immigrants (particularly marsupials and placental) during the latest Cretaceous-earliest Palaeocene had a profound influence on the composition of the South American mammal communities. During the Late Cretaceous these communities were dominated by native groups of Pangeic lineages, which represented more than 95% of the known genera, but during the Early Palaeocene 70% of South American mammals were derived from North American immigrants that had arrived during the Late Cretaceous-earliest Palaeocene, and by the Late Palaeocene all the South American mammals (with the possible exception of the xenarthrans) were descendants of these North American immigrants. In spite of the fact that no geological evidence is currently available to support the existence of a continuous land connection between the Americas during the Late Cretaceousearly Palaeocene, the fossil record is substantial enough to point to a temporary inter-American connection that permitted the beginning of a land-mammal exchange by the end of the Cretaceous. This interpretation is supported by recent geographic reconstructions of the Caribbean region. (Author)

Coparenting experiences in African American families: an examination of single mothers and their nonmarital coparents.

Science.gov (United States)

Gonzalez, Michelle; Jones, Deborah; Parent, Justin

2014-03-01

African American youth from single-mother homes continue to be overrepresented in statistics on risk behavior and delinquency, a trend that many be attributed to father-absence, socioeconomic disadvantage, and compromises in parenting more typical of single than two-parent families. Yet, this risk-focused perspective ignores a long-standing strength of the African American community, the involvement and potential protective impact of extended family members in childrearing. This study describes the experiences of 95 African American single mothers and their nonmarital coparents who participated in a study of African American single-mother families with an 11-16-year-old child. Specifically, the study examines: (a) the extent to which nonmarital coparents are involved in childrearing; (b) the relative levels of risk (i.e., depression, mother-coparent conflict) and protective (i.e., parenting) associated with maternal and coparent involvement; and (c) how similarly and/or differently coparent and mother variables operate with regard to youth externalizing problems. Findings reveal that a range of family members and other adults actively participate in childrearing in African American single-mother families, coparents do not differ from mothers on certain study variables (i.e., depression and mother-coparent conflict) but do for others (parenting), and coparent involvement is associated with youth adjustment in ways that are similar to our more established understanding of maternal involvement. The potential clinical implications of the findings are discussed and future research directions are highlighted. © 2014 FPI, Inc.

2004-10-01

Dramatic increases in same-race adoptions of African American children have stimulated interest in the experiences of these families, including those related to disclosure. Data from interviews with 27 African American adoptive parents (7 mothers and fathers interviewed conjointly, 13 mothers interviewed alone) from 20 different families revealed the following themes: (a) efforts to prevent trauma to the child; (b) respect for the child's differentness and birth history; (c) developmental decisions in disclosure; (d) children's questions as motivations for disclosure; and (e) parents' feelings about disclosure. Findings confirm the importance of psychoeducation regarding methods and timing of disclosure and provide support for comparative research on contemporary disclosure, including racial differences in process and content.

Influence of Surface Processes over Africa on the Atlantic Marine ITCZ and South American Precipitation.

Science.gov (United States)

Hagos, Samson M.; Cook, Kerry H.

2005-12-01

Previous studies show that the climatological precipitation over South America, particularly the Nordeste region, is influenced by the presence of the African continent. Here the influence of African topography and surface wetness on the Atlantic marine ITCZ (AMI) and South American precipitation are investigated.Cross-equatorial flow over the Atlantic Ocean introduced by north south asymmetry in surface conditions over Africa shifts the AMI in the direction of the flow. African topography, for example, introduces an anomalous high over the southern Atlantic Ocean and a low to the north. This results in a northward migration of the AMI and dry conditions over the Nordeste region.The implications of this process on variability are then studied by analyzing the response of the AMI to soil moisture anomalies over tropical Africa. Northerly flow induced by equatorially asymmetric perturbations in soil moisture over northern tropical Africa shifts the AMI southward, increasing the climatological precipitation over northeastern South America. Flow associated with an equatorially symmetric perturbation in soil moisture, however, has a very weak cross-equatorial component and very weak influence on the AMI and South American precipitation. The sensitivity of the AMI to soil moisture perturbations over certain regions of Africa can possibly improve the skill of prediction.

Time, Space, and National Belonging in The Namesake: Redrawing South Asian American Citizenship in the Shadow of 9/11

Directory of Open Access Journals (Sweden)

Sue Brennan

2011-03-01

Full Text Available The terms of national belonging after 9/11 for South Asian Americans have taken shape through a vague and depoliticized discourse around ethnic identity, one in which the clichés of multiculturalism and melting-pot nationalism stand in for the specific socioeconomic and historical conditions that helped form the South Asian diaspora in the US. This paper explores the ways in which Jhumpa Lahiri’s novel The Namesake and its cinematic adaptation by filmmaker Mira Nair challenge the erasure of South Asian American citizenship following 9/11. Recounting the journey of a young Bengali graduate student and his wife migrating to the US in the late 1960s, each text speaks back to the erasure of South Asian American citizenship through the materialization of time in space: while Lahiri foregrounds the state itself in producing the rhythms through which immigrants are assimilated into the nation, Nair creates a narrative world in which filmic space materializes many, and often competing, histories, unifying multiple temporalities and histories through the representations of space. I argue that the cinematic adaptation of The Namesake generates a new spatiotemporal state of affairs, one in which the iconography of 9/11 both challenges post-9/11 racial logics and destabilizes the singular, progressive, and institutionalized temporality through which Lahiri writes South Asian American immigrants back into nation.

Ethnopsychiatric interpretations of schizophrenic illness: the problem of nervios within Mexican-American families.

Science.gov (United States)

Jenkins, J H

1988-09-01

Among Mexican-American families, the concept of nervios (nerves) serves as a culturally meaningful illness category for a wide range of conditions, including schizophrenic disorders diagnosed according to psychiatric criteria. This article examines the nature and the meaning of nervios as a notion used by Mexican-American families to understand the schizophrenic illness of a relative. Family descriptions of the condition are presented and the emotional and symbolic meanings of the concept are discussed. The complex and somewhat ambiguous nature of folk conceptions is evidenced not only by variations in the description of nervios but also by the finding that nervios is but one way to view schizophrenic illness. It is suggested that a cultural preference for the term nervios is linked to the efforts of family members to reduce the stigma associated with a mental illness while also reinforcing the strength of family bonds and solidarity by fostering tolerant inclusion of the family member within the home. It is argued that the concept of nervios, and the family emotions that surround this folk label, may mediate the course and outcome of schizophrenic disorder.

To assess Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) benefit use across Arab American, Hispanic, and non-Arab/non-Hispanic families participating in the Michigan WIC program using point-of-sale Electronic Benefits Transfer data. Cross-sectional analysis using administrative data obtained from the Michigan WIC program, which collects Arab American ethnicity in addition to Hispanic ethnicity and race. Michigan. Families participating in the Michigan WIC program in March, 2012 (n = 152,989). Families redeeming all WIC benefits. Bivariate frequencies and multivariate logistic regression model identified characteristics of families associated with full redemption of WIC food benefits. About 12% of WIC families fully redeemed their benefits in March, 2012. Compared with non-Arab/non-Hispanic families, Arab American WIC families were significantly more likely to use all of their monthly WIC benefits, even after controlling for family characteristics (adjusted odds ratio, 3.6; 95% confidence interval, 3.4-3.8). Rates of redemption for Hispanic families, however, were the same as for non-Arab/non-Hispanic families (adjusted odds ratio, 1.0; 95% confidence interval, 0.9-1.0). State WIC programs moving toward implementation of Electronic Benefits Transfer should consider ways to enhance systems that would allow for more opportunities to conduct targeted analyses of benefit use across participant subpopulations. Findings point to low overall WIC benefit use. Additional research is needed to explore methods to increase benefit use among all WIC populations, including whether specific factors may contribute to higher redemptions among ethnic minorities, and whether they can be translated to other subpopulations.

Jewell, Shannon L; Luecken, Linda J; Gress-Smith, Jenna; Crnic, Keith A; Gonzales, Nancy A

2015-01-01

Low-income Mexican American women experience significant health disparities during the postpartum period. Contextual stressors, such as economic stress, are theorized to affect health via dysregulated cortisol output. However, cultural protective factors including strong family support may buffer the impact of stress. In a sample of 322 low-income Mexican American women (mother age 18-42; 82% Spanish-speaking; modal family income $10,000-$15,000), we examined the interactive influence of economic stress and family support at 6 weeks postpartum on maternal cortisol output (AUCg) during a mildly challenging mother-infant interaction task at 12 weeks postpartum, controlling for 6-week maternal cortisol and depressive symptoms. The interaction significantly predicted cortisol output such that higher economic stress predicted higher cortisol only among women reporting low family support. These results suggest that family support is an important protective resource for postpartum Mexican American women experiencing elevated economic stress.

Human consumption of a vagrant South American Fur Seal Arctocephalus australis (Carnivora: Otariidae in Brazil

Directory of Open Access Journals (Sweden)

S. Siciliano

2016-04-01

Full Text Available The South American Fur Seal Arctocephalus australis is one of the most widely distributed South American otariid species. In Brazil, during austral winter months specimens of A. australis are regularly found along the Rio Grande do Sul and Santa Catarina coasts. Occasionally, vagrants have been recorded along the southeastern coast but rarely moves north of Rio de Janeiro, at 23°S. On 01 May 2015, fishermen noticed in the surf zone an unidentified large animal in Ilhéus, Bahia, northeastern Brazil. Severely wounded, it was still alive when first spotted. Numerous shark bites were observed in the rostrum and flippers, the peduncle was severely lacerated and the intestines were protruding. The specimen was identified as an adult of South American Fur Seal based on the combination of the characteristic coloration of the pelage, head shape, body size, the relatively large eye size, and mainly due to the pronounced three cusped teeth in post canines. Fishermen decided to butcher the carcass and share the meat among their companions. The present record, however, is of special concern as human consumption South American Fur Seal seems to be unusual in Brazil. Pieces of meat were shared among fishermen. In addition, small pieces of blubber were used as bait in the local shark long-line fishery. Consumption of an injured and presumably weak marine mammal carcass points to an increasing risk of contact between potentially harmful viruses, bacteria and fungi and humans. This note represents an alert to public health specialists and wildlife authorities in Brazil. It calls the urgency of an outreach campaign advertising to the potential risks of ingesting bushmeat either from land or aquatic sources. 

Tectonothermal events of southeastern Brazil: Implications for consolidation of the South American platform

2001-01-01

The tectonothermal history of the South American Platform and it consolidation have to be analyzed considering different tectonic and stabilization stages. For that propose we have studied the Precambrian basement southwest of the city of Sao Paulo, which was consolidated and deformed during the Brasiliano Orogeny and later affected by Phanerozoic tectonics. Geological data from a northwest/southeast transect between Sao Roque and Jundiai - SP, were obtained through U/Pb, K/Ar and Ar/Ar mineral and whole rock studies. Metamorphic PT values, relation of brittle-ductile zone of felsic crustal rocks and fission track ages were also obtained. Such data were plotted on a temperature-time plot representing a preliminary overview of the geological evolution of this part of the South American platform. Recently dated highly deformed metaplutons from the Ribeira Belt suggest that convergence that preceded collision was underway by around 650 Ma. Low-grade (rarely reaching 4000 o C) metasediments and metavolcanics of the Sao Roque Group, interpreted to be a backarc basin that formed during active Brasiliano collision, yield a crystallization age of 627 Ma (Hackspacher et al., 2000). Syn-collisional granitoids with U/Pb zircon and monazite ages of 625 Ma (Janasi, 1999) provide more constraints on the timing of active collision. Temperatures of these calc-alkaline rocks can be considered around 650 o C. U/Pb zircon and monazite ages between 610 and 595 Ma obtained igneous bodies associated with transpressional tectonics place age constraints on the transition to a transpressional regime, with crystallization temperature around 580 o C. Related strike-slip shear zones in brittle-ductile transition, present K-Ar ages on biotite and hornblende between 600 and 580 Ma. The temperature interval for these greenschist grade shear zones is estimated between 450 and 300 o C. Apatite Fission Track Analysis (AFTA) near the Jundiuvira Shear Zone present a corrected Fission Track Age of 477

Objective To develop and test a family-centered behavioral weight loss intervention for African American adults with type 2 diabetes. Methods In this randomized trial, dyads consisting of African American adult with overweight or obesity and type 2 diabetes (index participant) paired with a family partner with overweight or obesity, but not diagnosed with diabetes, were assigned in a 2:1 ratio to a 20-week special intervention (SI) or delayed intervention (DI) control group. The primary outcome was weight loss among index participants at 20 weeks follow-up. Results One hundred-eight participants (54 dyads – 36 (SI) and 18 (DI) dyads) were enrolled: 81% females; mean age, 51 years; mean weight,103 kg; and mean BMI, 37 kg/m2. At post-intervention, 96 participants (89%) returned for follow-up measures. Among index participants, mean difference in weight loss between groups was −5.0 kg, pfamily interactions, and dietary, physical activity, and diabetes self-care behaviors. SI family partners also had significant weight loss (−3.9 kg (SI) vs. −1.0 kg (DI) p=0.02). Conclusions A family-centered, behavioral weight loss intervention led to clinically significant short-term weight loss among family dyads. PMID:27911049

Helminth parasites of South American fishes: current status and characterization as a model for studies of biodiversity.

2017-03-01

The South American subcontinent supports one of the world's most diverse and commercially very important ichthyofauna. In this context, the study of South American fish parasites is of increased relevance in understanding their key roles in ecosystems, regulating the abundance or density of host populations, stabilizing food webs and structuring host communities. It is hard to estimate the number of fish parasites in South America. The number of fish species studied for parasites is still low (less than 10%), although the total number of host-parasite associations (HPAs) found in the present study was 3971. Monogeneans, with 835 species (1123 HPAs, 28.5%), and trematodes, with 662 species (1127 HPAs, 30.9%), are the more diverse groups. Data gathered from the literature are useful to roughly estimate species richness of helminths from South American fish, even though there are some associated problems: the reliability of information depends on accurate species identification; the lack of knowledge about life cycles; the increasing number of discoveries of cryptic species and the geographically biased number of studies. Therefore, the closest true estimations of species diversity and distribution will rely on further studies combining both molecular and morphological approaches with ecological data such as host specificity, geographical distribution and life-cycle data. Research on biodiversity of fish parasites in South America is influenced by problems such as funding, taxonomic impediments and dispersion of research groups. Increasing collaboration, interchange and research networks in the context of globalization will enable a promising future for fish parasitology in South America.

Curare: the South American arrow poison.

Lee, M R

2005-02-01

The history of curare is both curious and convoluted. A product of South American culture it emerged in the sixteenth century from the mists of antiquity at the same time as quinine, coca, and chocolate. Like quinine, at first came the extract but no plant, and later the plant but no chemical compound. It took more than 300 years and the efforts of many explorers and scientists to resolve the problem. These included Condamine, Humboldt, Brodie, Waterton, Bernard, Dale, Walker, and King. Finally, the pure compound d-tubocurarine was isolated from the liana Chondrodendron and synthesised. Its specific physiological action was blockade of the effect of acetylcholine at the neuro-muscular junction. Such a paralytic poison could be used to kill oneself or others. The bizarre plot to kill the Prime Minister, Lloyd George, during the First World War is described. Fortunately this nefarious plan was thwarted by the Secret Service!

Splendid oddness: revisiting the curious trophic relationships of South American Pleistocene mammals and their abundance

Directory of Open Access Journals (Sweden)

RICHARD A. FARIÑA

2014-03-01

Full Text Available The South American Pleistocene mammal fauna includes great-sized animals that have intrigued scientists for over two centuries. Here we intend to update the knowledge on its palaeoecology and provide new evidence regarding two approaches: energetics and population density and relative abundance of fossils per taxa. To determine whether an imbalance exists, population density models were applied to several South American fossil faunas and the results compared to those that best describe the palaeoecology of African faunas. The results on the abundance study for Uruguay and the province of Buenos Aires during the Lujanian stage/age reveal that bulk-feeding ground sloths (Lestodon and Glossotherium were more represented in the first territory, while the more selective Scelidotherium and Megatherium were more abundant in the second. Although the obtained values were corrected to avoid size-related taphonomic biases, linear regressions of abundance vs. body mass plots did not fit the expected either for first or second consumers. South American Pleistocene faunas behave differently from what models suggest they should. Changes in sea level and available area could account for these differences; the possibility of a floodplain in the area then emerged could explain seasonal changes, which would modify the calculations of energetics and abundance.

Pereira, E M; Müller, G; Secchi, E; Pereira, J; Valente, A L S

2013-10-01

The aim of this work was to perform a systematic study to detect and quantify the digenetic trematode infections in South American sea lions from the southern Brazilian coast. Twenty-four South American sea lions, Otaria flavescens (Carnivora: Otaridae), were found dead along the coast of Rio Grande do Sul State, Brazil, between June 2010 and September of 2011. Two trematode species were found in the intestines of O. flavescens, i.e., Stephanoprora uruguayense (Digenea: Echinostomatidae) and Ascocotyle (Phagicola) longa (Digenea: Heterophyidae). Ascocotyle (P.) longa reached a prevalence of 33.3% and mean intensity of 248,500, whereas S. uruguayense showed a prevalence of 4.2% and mean intensity of 202. The 2 trematode species infecting sea lions were likely transmitted by feeding on mullets, Mugil platanus, that commonly harbor heterophyid metacercariae. The present work is the first report of digenetic trematodes infecting O. flavescens in Brazil. The high prevalence and mean intensity values of the 2 trematode species infecting sea lions in the present study suggest caution in human consumption of mullets and other fish, which can be infected with the metacercariae of these trematodes known to have zoonotic potential.

Sprauve-Holmes, Nancy E; Gaughan, John; Kaslow, Nadine J.

2009-01-01

Abstract Background Family violence among older women encompasses intimate partner violence (IPV) and elder maltreatment, both linked to poor health status. Little is known about the association between family violence and the health status of older innercity African American women. Methods One hundred fifty-eight African American women, aged ≥50, were interviewed in the ambulatory clinics of a large public hospital. Lifetime family violence exposure as an adult was measured by the Family Violence against Older Women (FVOW) scale; physical and mental health status were measured by the physical and mental component summary scores of the Short Form 8® scale. Results Mean participant age was 61.5 years (SD 7.1). Participants with FVOW scores in the top quartile were considered to have high lifetime family violence exposure. Participants with higher family violence exposure and those younger, unemployed, or disabled reported worse physical and mental health status. Lower income and not having Medicare were associated with worse physical and mental health status, respectively. Using stepwise linear regression techniques, only employment status and high family violence exposure were associated with worse physical (F = 7.16, p = 0.0011) and mental health (f = 7.09, p = 0.0012) status. Women with high FVOW scores reported physical and mental component summary scores that were 4.18 and 4.6 points lower, respectively, than those of women with lower FVOW scores. Conclusions Among older, innercity, African American women, lack of employment and high levels of family violence exposure as an adult are associated with worse physical and mental health status. Clinicians caring for older African American women need to be cognizant of the role both current and prior violence exposure may play in their patients' current health status. PMID:19183088

Public health initiatives encourage the public to discuss and record family health history (FHH) information, which can inform prevention and screening for a variety of conditions. Most research on FHH discussion and collection, however, has involved predominantly White participants and has not considered lay definitions of family or family communication patterns about health. This qualitative study of 32 African American women, 16 with a history of cancer, analyzed participants’ definitions of family, family communication about health, and collection of FHH information. “Family” was defined by biological relatedness, social ties, interactions, and proximity. Several participants noted using different definitions of family for different purposes (e.g. biomedical vs. social). Health discussions took place between and within generations and were influenced by structural relationships (e.g. sister) and characteristics of family members (e.g. trustworthiness). Participants described managing tensions between sharing health information and protecting privacy, especially related to generational differences in sharing information, fear of familial conflict or gossip, and denial (sometimes described as refusal to “own” or “claim” a disease). Few participants reported that anyone in their family kept formal FHH records. Results suggest FHH initiatives should address family tensions and communication patterns that affect discussion and collection of FHH information. PMID:25730634

High food insecurity has been demonstrated in rural American Indian households, but little is known about American Indian families in urban settings or the association of food insecurity with diet for these families. The purpose of this study was to examine the prevalence of food insecurity in American Indian households by urban-rural status, correlates of food insecurity in these households, and the relationship between food insecurity and diet in these households. Dyads consisting of an adult caregiver and a child (2-5 years old) from the same household in five urban and rural American Indian communities were included. Demographic information was collected, and food insecurity was assessed using two validated items from the USDA Household Food Security Survey. Factors associated with food insecurity were examined using logistic regression. Child and adult diets were assessed using food screeners. Coping strategies were assessed through focus group discussions. These cross-sectional baseline data were collected from 2/2013 through 4/2015 for the Healthy Children, Strong Families 2 randomized controlled trial of a healthy lifestyles intervention for American Indian families. A high prevalence of food insecurity was determined (61%) and was associated with American Indian ethnicity, lower educational level, single adult households, WIC participation, and urban settings (p = 0.05). Food insecure adults had significantly lower intake of vegetables (p insecure children had significantly higher intakes of fried potatoes (p insecurity. The prevalence of food insecurity in American Indian households in our sample is extremely high, and geographic designation may be an important contributing factor. Moreover, food insecurity had a significant negative influence on dietary intake for families. Understanding strategies employed by households may help inform future interventions to address food insecurity. ( NCT01776255 ). Registered: January 16, 2013. Date of enrollment

Prevalence and genetic diversity of haematozoa in South American waterfowl and evidence for intercontinental redistribution of parasites by migratory birds

Science.gov (United States)

Smith, Matthew M.; Ramey, Andy M.

2015-01-01

To understand the role of migratory birds in the movement and transmission of haematozoa within and between continental regions, we examined 804 blood samples collected from eleven endemic species of South American waterfowl in Peru and Argentina for infection by Haemoproteus, Plasmodium, and/or Leucocytozono blood parasites. Infections were detected in 25 individuals of six species for an overall apparent prevalence rate of 3.1%. Analysis of haematozoa mitochondrial DNA revealed twelve distinct parasite haplotypes infecting South American waterfowl, four of which were identical to lineages previously observed infecting ducks and swans sampled in North America. Analysis of parasite mitochondrial DNA sequences revealed close phylogenetic relationships between lineages originating from waterfowl samples regardless of continental affiliation. In contrast, more distant phylogenetic relationships were observed between parasite lineages from waterfowl and passerines sampled in South America for Haemoproteus and Leucocytozoon, suggesting some level of host specificity for parasites of these genera. The detection of identical parasite lineages in endemic, South American waterfowl and North American ducks and swans, paired with the close phylogenetic relationships of haematozoa infecting waterfowl on both continents, provides evidence for parasite redistribution between these regions by migratory birds.

The present study represents the first report on the gastrointestinal endoparasite fauna of a free-ranging "urban" colony of South American sea lions (Otaria flavescens) living within the city of Valdivia, Chile. A total of 40 individual faecal samples of South American sea lions were collected during the year 2012 within their natural habitat along the river Calle-Calle and in the local fish market of Valdivia. Coprological analyses applying sodium acetate acetic formalin methanol (SAF) technique, carbol fuchsin-stained faecal smears and Giardia/Cryptosporidium coproantigen ELISAs, revealed infections with 8 different parasites belonging to protozoan and metazoan taxa with some of them bearing anthropozoonotic potential. Thus, five of these parasites were zoonotic (Diphyllobothriidae gen. sp., Anisakidae gen. sp., Giardia, Cryptosporidium, and Balantidium). Overall, these parasitological findings included four new parasite records for Otaria flavescens, that is, Giardia, Cryptosporidium, Balantidium, and Otostrongylus. The current data serve as a baseline for future monitoring studies on anthropozoonotic parasites circulating in these marine mammals and their potential impact on public health.

To describe a cranial arthroscopic approach to the stifle of South American camelids and to report our clinical experience with camelid stifle arthroscopy. Experimental study and retrospective case series. (1) Cadaveric alpaca hindlimbs (n = 18; 9 alpacas); (2) 1 alpaca and 1 llama Polymethylmethacrylate joint casts (n = 2) were made to define stifle joint dimensions. Cadaveric stifle joints (n = 16) were evaluated arthroscopically to determine arthroscopic portal locations, describe the intraarticular anatomy, and report potential complications. An alpaca and a llama with stifle joint disease had diagnostic arthroscopy. Successful entry into the stifle joint was achieved in 16 cadaver limbs. Observed structures were: the suprapatellar pouch, articular surface of the patella, femoral trochlear ridges and groove, cranial aspect of the femoral condyles (n = 16); distal aspect of the cranial and proximal aspect of the caudal cruciate ligaments (14); and cranial aspects of the medial and lateral menisci (11), and cranial meniscotibial and intermeniscal ligaments (8). Stifle arthroscopy allowed for joint evaluation and removal of osteochondral fragments in 1 alpaca and 1 llama with naturally occurring stifle disease. Complications of cadaver or live procedures included minor cartilage scoring (3 stifles) and subcutaneous periarticular fluid accumulation (8 stifles). Arthroscopy provides a safe approach for diagnosis and treatment of stifle lesions in South American camelids. Copyright 2012 by The American College of Veterinary Surgeons.

2015-01-01

African American youth from single mother homes continue to be overrepresented in statistics on risk behavior and delinquency, a trend that many be attributed to father-absence, socioeconomic disadvantage, and compromises in parenting more typical of single than two-parent families. Yet, this risk-focused perspective ignores a long-standing strength of the African American community, the involvement and potential protective impact of extended family members in childrearing. This study describes the experiences of 95 African American single mothers and their non-marital coparents who participated in a study of African American single mother families with an 11 to 16 year old child. Specifically, the study examines: 1) the extent to which nonmarital coparents are involved in childrearing; 2) the relative levels of risk (i.e., depression, mother-coparent conflict) and protective (i.e., parenting) associated with maternal and coparent involvement; and 3) how similarly and/or differently coparent and mother variables operate with regard to youth externalizing problems. Findings reveal that a range of family members and other adults actively participate in childrearing in African American single mother families, coparents do not differ from mothers on certain study variables (i.e., depression and mother-coparent conflict) but do for others (parenting), and coparent involvement is associated with youth adjustment in ways that are similar to our more established understanding of maternal involvement. The potential clinical implications of the findings are discussed and future research directions are highlighted. PMID:24479612

Cole, Portia L; Secret, Mary C

2012-01-01

Job demands and workplace culture variables associated with work-family conflict stress, in addition to workplace racial bias, were examined for a national sample of 607 African American women in 16 Fortune 1000 companies. Similar to other studies, women in this sample who had dependents were younger, had supervisory responsibilities, and experienced a less positive workplace culture, and those in professional job positions with high job demand were most likely to experience work-family stress. Married women who experienced a more subtle form of workplace racial bias reported more work-family conflict stress. Implications for social work policy, practice, and research are considered.

Background/Aims Few obesity prevention trials have focused on young children and their families in the home environment, particularly in underserved communities. Healthy Children, Strong Families 2 is a randomized controlled trial of a healthy lifestyle intervention for American Indian children and their families, a group at very high risk of obesity. The study design resulted from our long-standing engagement with American Indian communities, and few collaborations of this type resulting in the development and implementation of a randomized clinical trial have been described. Methods Healthy Children, Strong Families 2 is a lifestyle intervention targeting increased fruit and vegetable intake, decreased sugar intake, increased physical activity, decreased TV/screen time, and two less-studied risk factors: stress and sleep. Families with young children from five American Indian communities nationwide were randomly assigned to a healthy lifestyle intervention ( Wellness Journey) augmented with social support (Facebook and text messaging) or a child safety control group ( Safety Journey) for 1 year. After Year 1, families in the Safety Journey receive the Wellness Journey, and families in the Wellness Journey start the Safety Journey with continued wellness-focused social support based on communities' request that all families receive the intervention. Primary (adult body mass index and child body mass index z-score) and secondary (health behaviors) outcomes are assessed after Year 1 with additional analyses planned after Year 2. Results To date, 450 adult/child dyads have been enrolled (100% target enrollment). Statistical analyses await trial completion in 2017. Lessons learned Conducting a community-partnered randomized controlled trial requires significant formative work, relationship building, and ongoing flexibility. At the communities' request, the study involved minimal exclusion criteria, focused on wellness rather than obesity, and included an active

Objective To examine the reliability and validity of the Family Asthma Management System Scale for low-income African-American children with poor asthma control and caregivers under stress. The FAMSS assesses eight aspects of asthma management from a family systems perspective. Methods Forty-three children, ages 8–13, and caregivers were interviewed with the FAMSS; caregivers completed measures of primary care quality, family functioning, parenting stress, and psychological distress. Children rated their relatedness with the caregiver, and demonstrated inhaler technique. Medical records were reviewed for dates of outpatient visits for asthma. Results The FAMSS demonstrated good internal consistency. Higher scores were associated with adequate inhaler technique, recent outpatient care, less parenting stress and better family functioning. Higher scores on the Collaborative Relationship with Provider subscale were associated with greater perceived primary care quality. Conclusions The FAMSS demonstrated relevant associations with asthma management criteria and family functioning for a low-income, African-American sample. PMID:19776230

Phylogenetic relationships of the South American Doradoidea (Ostariophysi: Siluriformes

Directory of Open Access Journals (Sweden)

José L. O. Birindelli

Full Text Available A phylogenetic analysis based on 311 morphological characters is presented for most species of the Doradidae, all genera of the Auchenipteridae, and representatives of 16 other catfish families. The hypothesis that was derived from the six most parsimonious trees support the monophyly of the South American Doradoidea (Doradidae plus Auchenipteridae, as well as the monophyly of the clade Doradoidea plus the African Mochokidae. In addition, the clade with Sisoroidea plus Aspredinidae was considered sister to Doradoidea plus Mochokidae. Within the Auchenipteridae, the results support the monophyly of the Centromochlinae and Auchenipterinae. The latter is composed of Tocantinsia, and four monophyletic units, two small with Asterophysusand Liosomadoras, and Pseudotatiaand Pseudauchenipterus, respectively, and two large ones with the remaining genera. Within the Doradidae, parsimony analysis recovered Wertheimeriaas sister to Kalyptodoras, composing a clade sister to all remaining doradids, which include Franciscodorasand two monophyletic groups: Astrodoradinae (plus Acanthodorasand Agamyxis and Doradinae (new arrangement. Wertheimerinae, new subfamily, is described for Kalyptodoras and Wertheimeria. Doradinae is corroborated as monophyletic and composed of four groups, one including Centrochirand Platydoras, the other with the large-size species of doradids (except Oxydoras, another with Orinocodoras, Rhinodoras, and Rhynchodoras, and another with Oxydorasplus all the fimbriate-barbel doradids. Based on the results, the species of Opsodoras are included in Hemidoras; and Tenellus, new genus, is described to include Nemadoras trimaculatus, N. leporhinusand Nemadoras ternetzi. Due to conflicting hypotheses of the phylogenetic position of Acanthodoras, Agamyxis, and Franciscodoras, these are considered as incertae sedisin Doradidae. All suprageneric taxa of the Doradoidea are diagnosed based on synapomorphic morphological characteristics.

Boundaries and opportunities: comparing slave family formation in the antebellum South.

Science.gov (United States)

Pargas, Damian Alan

2008-07-01

Our understanding of the marriage strategies and family formation of enslaved people remains clouded by disagreement among contemporary scholars. A perusal of the historical literature suggests that two issues lay at the root of this disagreement: First, scholars disagree over the extent to which slave family life was shaped by the external factors of slavery, or rather slave agency; and second, scholars appear reluctant to abandon their singular views of the slave family. This article addresses both of these gaps by formulating a middle ground in the slave agency debate and by redefining the slave family in plural form. An analysis of the boundaries and opportunities for family formation in northern Virginia and lowcountry South Carolina, this study shows that while the establishment of co-residential two-parent households was the ideal for slaves, not all were able to realize that ideal, and those that could not adapted their marriage strategies and family lives accordingly.

Family Resilience Resources in Coping With Child Sexual Abuse in South Africa.

Science.gov (United States)

Vermeulen, Theresa; Greeff, Abraham P

2015-01-01

The aim of this qualitative study was to identify resources of family resilience that help families cope with child sexual abuse. Data were collected from a purposeful sample of parents representing nine poor families living in the Western Cape Province, South Africa. The narratives of the participants were analyzed thematically. The results indicate that the families, despite adverse situations, utilized internal and external resilience resources. Internal resources were the parents' relationship with their children, their own emotional functioning and attitudes, the children's ability to cope with the abuse, boundaries in the family, insight into their children's emotional needs, and sibling relationships. External family resources were the support of extended family members, friends, and a local community-based nonprofit organization working with child sexual abuse and schools. The empowering role of the identified resources for family resilience should be enhanced in interventions, while future studies could further explore these aspects in families confronted with child sexual abuse.

The purpose of this review is to explore cultural influences on the experiences of Korean, Korean American, and Caucasian American family caregivers caring for frail older adults in terms of the selection of a primary caregiver, caregiving motivation, support/help-seeking, and negative emotional responses(depression and burden). Seven electronic databases were searched to retrieve studies from 1966 to 2005. Thirty-two studies were identified. This review supported cultural influences on the selection of primary caregiver, caregiving motivation, and support/help-seeking among the three caregiver groups. In Korean caregivers, the major primary caregivers were daughters-in-law while among Korean American and Caucasian American caregivers, the major primary caregivers were daughters or spouses. As a major caregiving motivation, Caucasian American caregivers reported filial affection while Korean caregivers and Korean American caregivers reported filial obligation. Korean caregivers reported higher extended family support, while Caucasian American caregivers reported higher utilization of formal support. Korean caregivers showed the highest levels of depression followed by Korean American caregivers and Caucasian American caregivers. In order to develop culturally appropriate interventions and policies, more research is needed to further explain these differences among the three groups, especially regarding support/help-seeking and negative emotional responses.

"So we would all help pitch in:" The family literacy practices of low-income African American mothers of preschoolers.

Jarrett, Robin L; Hamilton, Megan-Brette; Coba-Rodriguez, Sarai

2015-01-01

The development of emergent literacy skills are important for the development of later literacy competencies and affect school readiness. Quantitative researchers document race- and social class-based disparities in emergent literacy competence between low-income African American and middle-income White children. Some researchers suggest that deficits in parenting practices account for limited literacy skills among low-income African American children. A small body of qualitative research on low-income African American families finds that despite economic challenges, some African American families were actively engaged in promoting child literacy development. Using qualitative interviews that emphasize family strengths, we add to this small body of research to highlight positive family practices obscured in many quantitative analyses that concentrate on family shortcomings. Specifically, we examine in-home literacy practices and child literacy development with a sample of low-income African American mothers (families) of preschoolers. Key findings include identification of various literacy activities promoting child literacy development and inclusion of multiple family members assisting in literacy activities. These findings add to substantive discussions of emergent literacy and resilience. Insights from the qualitative interviews also provide culturally-sensitive recommendations to childhood educators and speech-language pathologists (SLP) who work with low-income African American families and children. Reader should recognize that (1) there is not a 'right' phenotype and therefore not a right form of environmental input and (2) that context matters (at both the level of the cell and the individual organism).

2015-05-01

The Families Improving Together (FIT) randomized controlled trial tests the efficacy of integrating cultural tailoring, positive parenting, and motivational strategies into a comprehensive curriculum for weight loss in African American adolescents. The overall goal of the FIT trial is to test the effects of an integrated intervention curriculum and the added effects of a tailored web-based intervention on reducing z-BMI in overweight African American adolescents. The FIT trial is a randomized group cohort design the will involve 520 African American families with an overweight adolescent between the ages of 11-16 years. The trial tests the efficacy of an 8-week face-to-face group randomized program comparing M + FWL (Motivational Plus Family Weight Loss) to a comprehensive health education program (CHE) and re-randomizes participants to either an 8-week on-line tailored intervention or control on-line program resulting in a 2 (M + FWL vs. CHE group) × 2 (on-line intervention vs. control on-line program) factorial design to test the effects of the intervention on reducing z-BMI at post-treatment and at 6-month follow-up. The interventions for this trial are based on a theoretical framework that is novel and integrates elements from cultural tailoring, Family Systems Theory, Self-Determination Theory and Social Cognitive Theory. The intervention targets positive parenting skills (parenting style, monitoring, communication); cultural values; teaching parents to increase youth motivation by encouraging youth to have input and choice (autonomy-support); and provides a framework for building skills and self-efficacy through developing weight loss action plans that target goal setting, monitoring, and positive feedback.

Integrated team-based primary care is an international imperative. This is required more so in Africa, where fragmented verticalised care dominates. South Africa is trying to address this with health reforms, including Primary Health Care Re-engineering. Family physicians are already contributing to primary care despite family medicine being only fully registered as a full specialty in South Africa in 2008. However the views of leaders on family medicine and the role of family physicians is not clear, especially with recent health reforms. The aim of this study was to understand the views of key government and academic leaders in South Africa on family medicine, roles of family physicians and human resource issues. This was a qualitative study with academic and government leaders across South Africa. In-depth interviews were conducted with sixteen purposively selected leaders using an interview guide. Thematic content analysis was based on the framework method. Whilst family physicians were seen as critical to the district health system there was ambivalence on their leadership role and 'specialist' status. National health reforms were creating both threats and opportunities for family medicine. Three key roles for family physicians emerged: supporting referrals; clinical governance/quality improvement; and providing support to community-oriented care. Respondents' urged family physicians to consolidate the development and training of family physicians, and shape human resource policy to include family physicians. Family physicians were seen as critical to the district health system in South Africa despite difficulties around their precise role. Whilst their role was dominated by filling gaps at district hospitals to reduce referrals it extended to clinical governance and developing community-oriented primary care - a tall order, requiring strong teamwork. Innovative team-based service delivery is possible despite human resource challenges, but requires family

This study examines two sources of informal support-perceived family and friend support-and the psychological well-being-self-esteem, depression and loneliness-of 150 Chinese and 145 American elders. There were no significant differences between the elderly American and Chinese persons' mean scores on family and friend support. The multiple linear regression analyses with interaction terms (country x family support and country x friend support), however, indicated that the relationship between family support and depression and family support and loneliness was stronger for the Chinese elderly than the US elderly. Conversely, the relationship between friend support and depression and friend support and loneliness is stronger for US elderly than Chinese elderly. The implications of these findings for social work practice in both countries is discussed.

A deforestation-induced tipping point for the South American monsoon system

Science.gov (United States)

Boers, Niklas; Marwan, Norbert; Barbosa, Henrique M. J.; Kurths, Jürgen

2017-01-01

The Amazon rainforest has been proposed as a tipping element of the earth system, with the possibility of a dieback of the entire ecosystem due to deforestation only of parts of the rainforest. Possible physical mechanisms behind such a transition are still subject to ongoing debates. Here, we use a specifically designed model to analyse the nonlinear couplings between the Amazon rainforest and the atmospheric moisture transport from the Atlantic to the South American continent. These couplings are associated with a westward cascade of precipitation and evapotranspiration across the Amazon. We investigate impacts of deforestation on the South American monsoonal circulation with particular focus on a previously neglected positive feedback related to condensational latent heating over the rainforest, which strongly enhances atmospheric moisture inflow from the Atlantic. Our results indicate the existence of a tipping point. In our model setup, crossing the tipping point causes precipitation reductions of up to 40% in non-deforested parts of the western Amazon and regions further downstream. The responsible mechanism is the breakdown of the aforementioned feedback, which occurs when deforestation reduces transpiration to a point where the available atmospheric moisture does not suffice anymore to release the latent heat needed to maintain the feedback.

Evans, Bronwynne C; Coon, David W; Belyea, Michael J; Ume, Ebere

2017-07-01

Specific stressors associated with caregiving in Mexican American (MA) families are not well documented, yet caregiving issues are paramount because informal care for parents is central to their culture. Although MA families who band together to provide care for one member are not unique, the literature does not describe the phenomenon of collective caregiving, which may be widespread but unrecognized. This article describes these understudied families who are poorly served by contemporary health systems because their characteristics are unknown. Descriptive, multisite, longitudinal mixed-methods study of MA caregiving families. We identified three types of collective caregivers: those providing care for multiple family members simultaneously, those providing care successively to several family members, and/or those needing care themselves during their caregiving of others. Collective caregiving of MA elders warrants further investigation. Exploration of collective caregiving may provide a foundation for tailored family interventions.

Family obligation values and family assistance behaviors: protective and risk factors for Mexican-American adolescents' substance use.

Science.gov (United States)

Telzer, Eva H; Gonzales, Nancy; Fuligni, Andrew J

2014-02-01

Adolescent substance use is one of today's most important social concerns, with Latino youth exhibiting the highest overall rates of substance use. Recognizing the particular importance of family connection and support for families from Mexican backgrounds, the current study seeks to examine how family obligation values and family assistance behaviors may be a source of protection or risk for substance use among Mexican-American adolescents. Three hundred and eighty-five adolescents (51% female) from Mexican backgrounds completed a questionnaire and daily diary for 14 consecutive days. Results suggest that family obligation values are protective, relating to lower substance use, due, in part, to the links with less association with deviant peers and increased adolescent disclosure. In contrast, family assistance behaviors are a source of risk within high parent-child conflict homes, relating to higher levels of substance use. These findings suggest that cultural values are protective against substance use, but the translation of these values into behaviors can be a risk factor depending upon the relational context of the family.

Adolescent substance use is one of today’s most important social concerns, with Latino youth exhibiting the highest overall rates of substance use. Recognizing the particular importance of family connection and support for families from Mexican backgrounds, the current study seeks to examine how family obligation values and family assistance behaviors may be a source of protection or risk for substance use among Mexican-American adolescents. Three hundred and eighty-five adolescents (51% female) from Mexican backgrounds completed a questionnaire and daily diary for 14 consecutive days. Results suggest that family obligation values are protective, relating to lower substance use, due, in part, to the links with less association with deviant peers and increased adolescent disclosure. In contrast, family assistance behaviors are a source of risk within high parent-child conflict homes, relating to higher levels of substance use. These findings suggest that cultural values are protective against substance use, but the translation of these values into behaviors can be a risk factor depending upon the relational context of the family.

Time, Space, and National Belonging in The Namesake: Redrawing South Asian American Citizenship in the Shadow of 9/11

The terms of national belonging after 9/11 for South Asian Americans have taken shape through a vague and depoliticized discourse around ethnic identity, one in which the clichés of multiculturalism and melting-pot nationalism stand in for the specific socioeconomic and historical conditions that helped form the South Asian diaspora in the US. This paper explores the ways in which Jhumpa Lahiri’s novel The Namesake and its cinematic adaptation by filmmaker Mira Nair challenge the erasure of South Asian American citizenship following 9/11. Recounting the journey of a young Bengali graduate student and his wife migrating to the US in the late 1960s, each text speaks back to the erasure of South Asian American citizenship through the materialization of time in space: while Lahiri foregrounds the state itself in producing the rhythms through which immigrants are assimilated into the nation, Nair creates a narrative world in which filmic space materializes many, and often competing, histories, unifying multiple temporalities and histories through the representations of space. I argue that the cinematic adaptation of The Namesake generates a new spatiotemporal state of affairs, one in which the iconography of 9/11 both challenges post-9/11 racial logics and destabilizes the singular, progressive, and institutionalized temporality through which Lahiri writes South Asian American immigrants back into nation.

However, HIV-infected women may not discuss reproductive intentions with providers due to anticipation of negative reactions and stigma. This study aimed to identify correlates of patient–provider family planning discussions among HIV-infected women in rural South Africa, an area with high rates of antenatal HIV and suboptimal rates of prevention of mother-to-child transmission (PMTCT of HIV. Participants were N=673 pregnant HIV-infected women who completed measures of family planning discussions and knowledge, depression, stigma, intimate partner violence, and male involvement. Participants were, on average, 28 ± 6 years old, and half of them had completed at least 10–11 years of education. Most women were unemployed and had a monthly income of less than ~US$76. Fewer than half of the women reported having family planning discussions with providers. Correlates of patient–provider family planning discussions included younger age, discussions about PMTCT of HIV, male involvement, and decreased stigma (p < 0.05. Depression was indirectly associated with patient–provider family planning discussions through male involvement (b = −0.010, bias-corrected 95% confidence interval [bCI] [−0.019, −0.005].

The current study aimed to describe the effect of an educational program on RN-initiated efforts to involve family caregivers in delirium care. A descriptive qualitative study was performed. A purposive sample of 12 RNs who participated in a one group, pre-post evaluation of a delirium educational program, and a nominated sample of six family caregivers of patients who had been cared for by RNs in the program participated in individual, in-depth interviews. The qualitative findings indicated that the inclusion of a delirium brochure in ward orientation on admission, with reinforcement during shift changes, and RN-initiated engagement with family caregivers promoted family caregiver involvement in delirium prevention. Further studies in South Korea are needed to determine which family-centered nursing care interventions are culturally appropriate and most effective for RNs and family caregivers in delirium care.

Metagenomic Survey of Viral Diversity Obtained from Feces of Subantarctic and South American Fur Seals.

Directory of Open Access Journals (Sweden)

Mariana Kluge

Full Text Available The Brazilian South coast seasonally hosts numerous marine species, observed particularly during winter months. Some animals, including fur seals, are found dead or debilitated along the shore and may harbor potential pathogens within their microbiota. In the present study, a metagenomic approach was performed to evaluate the viral diversity in feces of fur seals found deceased along the coast of the state of Rio Grande do Sul. The fecal virome of two fur seal species was characterized: the South American fur seal (Arctocephalus australis and the Subantarctic fur seal (Arctocephalus tropicalis. Fecal samples from 10 specimens (A. australis, n = 5; A. tropicalis, n = 5 were collected and viral particles were purified, extracted and amplified with a random PCR. The products were sequenced through Ion Torrent and Illumina platforms and assembled reads were submitted to BLASTx searches. Both viromes were dominated by bacteriophages and included a number of potentially novel virus genomes. Sequences of picobirnaviruses, picornaviruses and a hepevirus-like were identified in A. australis. A rotavirus related to group C, a novel member of the Sakobuvirus and a sapovirus very similar to California sea lion sapovirus 1 were found in A. tropicalis. Additionally, sequences of members of the Anelloviridae and Parvoviridae families were detected in both fur seal species. This is the first metagenomic study to screen the fecal virome of fur seals, contributing to a better understanding of the complexity of the viral community present in the intestinal microbiota of these animals.

Background Significant racial disparities exist in the US unplanned pregnancy rate. We conducted a qualitative study using the theory of planned behavior as a framework to describe how low-income, African-American women approach family planning. Study Design Structured focus groups were held with adult, low-income, non-pregnant, African-American women in Connecticut. Data were collected using a standardized discussion guide, and audio-taped and transcribed. Four, independent researchers coded the transcripts using the constant comparative method. Codes were organized into over-arching themes. Results Contraceptive knowledge was limited with formal education often occurring after sexual debut. Attitudes about contraception were overtly negative with method effectiveness being judged by the experience of side effects. Family and friends strongly influence contraceptive decisions while male partners are primarily seen as a barrier. Contraceptive pills are perceived as readily accessible although compliance is considered a barrier. Conclusions Contraception education should occur before sexual debut, should involve trusted family and community members, and should positively frame issues in terms of achieving life goals.

Confronting developmental tasks and challenges associated with bridging two different cultures, Asian American adolescent girls face increasing risks for substance use. Identifying risk and protective factors in this population is essential, particularly when those factors can inform preventive programs. Guided by family interaction theory, the present cross-sectional study explored the associations of psychological and familial factors with use of alcohol, prescription drugs, and other drugs among early-adolescent Asian American girls. Between August 2007 and March 2008, 135 pairs of Asian American girls (mean age 13.21 years, SD=0.90) and their mothers (mean age 39.86 years, SD=6.99) were recruited from 19 states that had significant Asian populations. Girls and mothers each completed an online survey. Relative to girls who did not use substances, girls who did had higher levels of depressive symptoms, perceived peer substance use, and maternal substance use. Multiple logistic regression modeling revealed that they also had significantly lower levels of body satisfaction, problem-solving ability, parental monitoring, mother-daughter communication, family involvement, and family rules about substance use. Household composition, acculturation, and academic achievement were not associated with girls' substance use. These findings point to directions for substance abuse prevention programming among Asian American girls.

2015-12-01

This article proposes explanations for the transformation of American families over the past two centuries. I describe the impact on families of the rise of male wage labor beginning in the nineteenth century and the rise of female wage labor in the twentieth century. I then examine the effects of decline in wage labor opportunities for young men and women during the past four decades. I present new estimates of a precipitous decline in the relative income of young men and assess its implications for the decline for marriage. Finally, I discuss explanations for the deterioration of economic opportunity and speculate on the impact of technological change on the future of work and families.

Using data from a socioeconomically diverse sample of Chinese American children (n = 258, aged 6-9 years) in immigrant families, we examined the concurrent relations among neighborhood economic disadvantage and concentration of Asian residents, parenting styles, and Chinese American children's externalizing and internalizing problems. Neighborhood characteristics were measured with 2000 U.S. Census tract-level data, parents (mostly mothers) rated their own parenting styles, and parents and teachers rated children's behavioral problems. Path analysis was conducted to test two hypotheses: (a) parenting styles mediate the relations between neighborhood characteristics and children's behavioral problems, and (b) children's behavioral problems mediate the relations between neighborhood and parenting styles. We found that neighborhood Asian concentration was positively associated with authoritarian parenting, which in turn was associated with Chinese American children's higher externalizing and internalizing problems (by parents' reports). In addition, neighborhood economic disadvantage was positively related to children's externalizing problems (by parents' reports), which in turn predicted lower authoritative parenting. The current results suggest the need to consider multiple pathways in the relations among neighborhood, family, and child adjustment, and they have implications for the prevention and intervention of behavioral problems in Chinese American children.

Full Text Available Through in-depth interviews with 21 parents and 12 children in lesbian/gayparented families, we explored the experiences of this unique family form in South African schools. Specifically, families reflected on their positive and negative experiences in the children’s education and used these reflections to offer advice to teachers and administrators wishing better to support lesbian/ gay-parented families. The results of our study offer an understanding of the challenges and needs of this diverse family in the school system, as well as a starting point for administrators and teachers wanting to create inclusive environments for all family types.

In this paper, we describe the first phase of a research project designed to quantify the role of race and cultural identity in HIV-related stigma. The ultimate purpose is to develop an intervention that could be implemented in Black and Colored communities in Cape Town, South Africa. The PEN-3 model provided the theoretical basis for this research. A total of 397 Black and Colored participants were recruited from two communities to complete a 16-item multi-part questionnaire that was developed based on focus groups and key informant interviews. A total of 196 questionnaires were administered in Mitchell's Plain and 201 were administered in Gugulethu. Both communities are located approximately 20 km outside the city of Cape Town in an area known as the Cape Flats. Data were collected on individuals' perceptions of stigma in the contexts of the family, healthcare settings, and the community. However, only the family context is explored here. Participants were also asked to identify what they felt should be the most important area of emphasis for researchers in eliminating stigma. Similarities and differences in perceptions between Black and Colored South Africans were examined. Data were compiled on the family support domain of stigma. Though most either disagreed or were neutral, nearly equal numbers of Blacks and Coloreds thought stigma occurred in families. Blacks were also more likely than Coloreds to report experiencing stigma in their families. Both Blacks and Coloreds felt the family should be the most important focus of interventions for eliminating HIV-related stigma. Within the context of the family race, cultural values, and religious and spiritual values all contribute to HIV stigma in South Africa. Interventions should address the role of stigma within families in order to promote better HIV prevention, treatment, and care.

Prosopis pod production - comparison of North American, South American, Hawaiian, and African germplasm in young plantations

Felker, P.; Clark, P.R.; Osborn, J.F.; Cannell, G.H.

Prosopis pod production was compared in 3 field trials in southern California, i.e., a typical orchard planting, an irrigation trial, and a heat/drought stress trial. Thirteen species representing North American, South American, Hawaiian, and African germplasm were evaluated. Hawaiian and African accessions were eliminated from the irrigation trial by a minus 5/sup 0/C temperature. The most productive pod producers were P. velutina accessions from southern Arizona. In the fifth season, 5 trees of the most productive accession, i.e. P. velutina 32 had a mean pod production of 7.2 kg/tree with a range of 3.2-12.2 kg/tree. P. chilensis and P. alba trees of the same age were much larger but had less pod production. Pod production estimates of 3000-4000 kg/ha were obtained in the dry irrigation treatment by P. velutina 20 which received 370 mm rainfall in the year preceding harvest.

Within the 52 health districts in South Africa, the family physician is seen as the clinical leader within a multi-professional district health team. Family physicians must be competent to meet 90% of the health needs of the communities in their districts. The eight university departments of Family Medicine have identified five unit standards, broken down into 85 training outcomes, for postgraduate training. The family medicine registrar must prove at the end of training that all the required training outcomes have been attained. District health managers must be assured that the family physician is competent to deliver the expected service. The Colleges of Medicine of South Africa (CMSA) require a portfolio to be submitted as part of the uniform assessment of all registrars applying to write the national fellowship examinations. This study aimed to achieve a consensus on the contents and principles of the first national portfolio for use in family medicine training in South Africa. A workshop held at the WONCA Africa Regional Conference in 2009 explored the purpose and broad contents of the portfolio. The 85 training outcomes, ideas from the WONCA workshop, the literature, and existing portfolios in the various universities were used to develop a questionnaire that was tested for content validity by a panel of 31 experts in family medicine in South Africa, via the Delphi technique in four rounds. Eighty five content items (national learning outcomes) and 27 principles were tested. Consensus was defined as 70% agreement. For those items that the panel thought should be included, they were also asked how to provide evidence for the specific item in the portfolio, and how to assess that evidence. Consensus was reached on 61 of the 85 national learning outcomes. The panel recommended that 50 be assessed by the portfolio and 11 should not be. No consensus could be reached on the remaining 24 outcomes and these were also omitted from the portfolio. The panel recommended

Casado, Banghwa; Sacco, Paul

2012-05-01

Despite the rapid growth of older ethnic minority populations, knowledge is limited about informal caregiving among these groups. Our aim was to identify correlates of caregiver burden among family caregivers of older Korean Americans (KAs). A cross-sectional survey collected data from 146 KA caregivers. Using a modified stress-appraisal model, we examined background and context characteristics (caregiver sex, relationship to care recipient, college education, English proficiency, time in caregiving role, family support network, friend support network), a primary stressor (care recipient functional dependency), a primary appraisal (caregiving hours), and resources (family agreement, care management self-efficacy, service use self-efficacy) as potential correlates of caregiver burden. Interactions between the primary stressor, primary appraisal, and resources were also tested. Being female and the care recipient's spouse were associated with higher burden. Conversely, a larger family support network, greater family agreement, and greater care management self-efficacy were associated with lower burden. A significant interaction was detected between functional dependency and family agreement; higher levels of family agreement moderated the association between care recipient functional dependency and caregiver burden. Interventions to reduce caregiver burden in KA caregivers may be more effective if they include approaches specifically designed to build family support, improve family agreement, and increase caregivers' self-efficacy.

Neotropics and natural ingredients for pharmaceuticals: why isn't South American biodiversity on the crest of the wave?

Science.gov (United States)

Desmarchelier, Cristian

2010-06-01

Despite the advent of biotechnology and modern methods of combinatorial chemistry and rational drug design, nature still plays a surprisingly important role as a source of new pharmaceutical compounds. These are marketed either as herbal drugs or as single active ingredients. South American tropical ecosystems (or the Neotropics) encompass one-third of the botanical biodiversity of the planet. For centuries, indigenous peoples have been using plants for healing purposes, and scientists are making considerable efforts in order to validate these uses from a pharmacological/phytochemical point of view. However, and despite the unique plant diversity in the region, very few natural pharmaceutical ingredients from this part of the world have reached the markets in industrialized countries. The present review addresses the importance of single active ingredients and herbal drugs from South American flora as natural ingredients for pharmaceuticals; it highlights the most relevant cases in terms of species of interest; and discusses the key entry barriers for these products in industrialized countries. It explores the reasons why, in spite of the region's competitive advantages, South American biodiversity has been a poor source of natural ingredients for the pharmaceutical industry.

2010-01-01

SUMMARY Trypanosoma cruzi (Tc), the causative agent of Chagas disease, is a diverse species with 2 primary genotypes, TcI and TcII, with TcII further subdivided into 5 subtypes (IIa–e). This study evaluated infection dynamics of 4 genetically and geographically diverse T. cruzi strains in 2 South American reservoirs, degus (Octodon degus) and grey short-tailed opossums (Monodelphis domestica). Based on prior suggestions of a genotype-host association, we hypothesized that degus (placental) would more readily become infected with TcII strains while short-tailed opossums (marsupial) would be a more competent reservoir for a TcI strain. Individuals (n = 3) of each species were intraperitoneally inoculated with T. cruzi trypomastigotes of TcIIa [North America (NA)-raccoon (Procyon lotor) origin], TcI [NA-Virginia opossum (Didelphis virginiana)], TcIIb [South America (SA)-human], TcIIe (SA-Triatoma infestans), or both TcI and TcIIa. Parasitaemias in experimentally infected degus peaked earlier (7–14 days post-inoculation (p.i.)) compared with short-tailed opossums (21–84 days p.i.). Additionally, peak parasitaemias were higher in degus; however, the duration of detectable parasitaemias for all strains, except TcIIa, was greater in short-tailed opossums. Infections established in both host species with all genotypes, except for TcIIa, which did not establish a detectable infection in short-tailed opossums. These results indicate that both South American reservoirs support infections with these isolates from North and South America; however, infection dynamics differed with host and parasite strain.

Full Text Available Abstract Background High food insecurity has been demonstrated in rural American Indian households, but little is known about American Indian families in urban settings or the association of food insecurity with diet for these families. The purpose of this study was to examine the prevalence of food insecurity in American Indian households by urban-rural status, correlates of food insecurity in these households, and the relationship between food insecurity and diet in these households. Methods Dyads consisting of an adult caregiver and a child (2–5 years old from the same household in five urban and rural American Indian communities were included. Demographic information was collected, and food insecurity was assessed using two validated items from the USDA Household Food Security Survey. Factors associated with food insecurity were examined using logistic regression. Child and adult diets were assessed using food screeners. Coping strategies were assessed through focus group discussions. These cross-sectional baseline data were collected from 2/2013 through 4/2015 for the Healthy Children, Strong Families 2 randomized controlled trial of a healthy lifestyles intervention for American Indian families. Results A high prevalence of food insecurity was determined (61% and was associated with American Indian ethnicity, lower educational level, single adult households, WIC participation, and urban settings (p = 0.05.

Chen, Stephen H; Hua, Michelle; Zhou, Qing; Tao, Annie; Lee, Erica H; Ly, Jennifer; Main, Alexandra

2014-01-01

Direct and indirect/mediated relations of (a) children's and parents' cultural orientations and (b) parent-child gaps in cultural orientations to children's psychological adjustment were examined in a socioeconomically diverse sample of 258 Chinese American children (age = 6-9 years) from immigrant families. Parents reported on children's and their own Chinese and American orientations in language proficiency, media use, and social relationships. Parents and teachers rated children's externalizing and internalizing problems and social competence. Using structural equation modeling, we found evidence for both the effects of children's and parents' cultural orientations and the effects of parent-child gaps. Specifically, children's American orientations across domains were associated with their better adjustment (especially social competence). These associations were partly mediated by authoritative parenting. Parents' English and Chinese media use were both associated with higher authoritative parenting, which in turn was associated with children's better adjustment. Furthermore, greater gaps in parent-child Chinese proficiency were associated with children's poorer adjustment, and these relations were partly mediated by authoritative parenting. Together, the findings underscore the complex relations between immigrant families' dual orientations to the host and heritage cultures and children's psychological adjustment.

Climate change and American Bullfrog invasion: what could we expect in South America?

Directory of Open Access Journals (Sweden)

Javier Nori

Full Text Available BACKGROUND: Biological invasion and climate change pose challenges to biodiversity conservation in the 21(st century. Invasive species modify ecosystem structure and functioning and climatic changes are likely to produce invasive species' range shifts pushing some populations into protected areas. The American Bullfrog (Lithobates catesbeianus is one of the hundred worst invasive species in the world. Native from the southeast of USA, it has colonized more than 75% of South America where it has been reported as a highly effective predator, competitor and vector of amphibian diseases. METHODOLOGY/PRINCIPAL FINDINGS: We modeled the potential distribution of the bullfrog in its native range based on different climate models and green-house gases emission scenarios, and projected the results onto South America for the years of 2050 and 2080. We also overlaid projected models onto the South American network of protected areas. Our results indicate a slight decrease in potential suitable area for bullfrog invasion, although protected areas will become more climatically suitable. Therefore, invasion of these sites is forecasted. CONCLUSION/SIGNIFICANCE: We provide new evidence supporting the vulnerability of the Atlantic Forest Biodiversity Hotspot to bullfrog invasion and call attention to optimal future climatic conditions of the Andean-Patagonian forest, eastern Paraguay, and northwestern Bolivia, where invasive populations have not been found yet. We recommend several management and policy strategies to control bullfrog invasion and argue that these would be possible if based on appropriate articulation among government agencies, NGOs, research institutions and civil society.

Clinicians meet people from different ethnic backgrounds, yet need to respond in culturally sensitive ways. This article focuses on Asian American families. Within a randomized controlled trial of family therapy commenced during palliative care and continued into bereavement, 3 families of Asian American background were examined qualitatively from a cultural perspective by listening to recordings of 26 therapy sessions and reviewing detailed supervision notes compiled by each therapist. A synopsis of each family's therapy narrative is presented. Prominent themes include family closeness, respect for hierarchy within the family, gender-determined roles, intergenerational tensions, preoccupation with shame and limited emotional expressiveness. Family therapists working with culturally diverse families need to pay thoughtful attention to ethnic issues as they strive to support them during palliative care and bereavement.

Neighborhood characteristics, parenting styles, and children's behavioral problems in Chinese American immigrant families

Using data from a socioeconomically diverse sample of Chinese American children (n = 258, aged 6-9 years) in immigrant families, we examined the concurrent relations among neighborhood economic disadvantage and concentration of Asian residents, parenting styles, and Chinese American children's externalizing and internalizing problems. Neighborhood characteristics were measured with 2000 U.S. Census tract-level data, parents (mostly mothers) rated their own parenting styles, and parents and te...

Stigma of poverty. The discursive construction of ­"South" term in Latin American countries

Directory of Open Access Journals (Sweden)

GÓMEZ QUINTERO, Juan David

2014-05-01

Full Text Available This article reflects a general knowledge and a macro-paradigmatic contribution of developmentalist discourses, in particular, its modernist and Eurocentric roots. In particular we analyze the artificiality of the discursive construction of certain categories that represent geopolitical stigma of poverty, such as ­Third World® or ­South® or ­underdeveloped® adopted in the field of international relations and the development cooperation. It notes that there are not metaphors opposite (North-South in its own right, the ­South® is not the opposite of the ­North®, but its negative extension, as evidenced by the imaginarium of most Latin American countries. The metaphors that stigmatize poverty are symbolic discourse used to define in a European way the identity of the winner (rich people.

Gallbladder cancer: South American experience.

Arroyo, Gerardo F; Gentile, Alberto; Parada, Luis A

2016-10-01

Large differences in terms of incidence and mortality due to gallbladder cancer (GBC) have been reported worldwide. Moreover, it seems that GBC has unique characteristics in South America. We surveyed the literature looking for information about the epidemiology, basic and translational research, and clinical trials performed in South America in order to critically analyze the magnitude of this health problem in the region. Compared to other geographic areas, age-standardized mortality rates (ASMR) for GBC in women are very high, particularly in many western areas of South America. Genetic, as well as dietary and environmental factors likely contribute to the pathogenesis of this disease in the area. Compared to other regions the profile of abnormalities of key genes such as KRAS and TP53 in GBC seems to slightly differ in South America, while the clinical behavior appears to be similar with a median overall survival (OS) of 6.5 to 8 months in advanced GBC. In contrast to Europe and USA, prophylactic cholecystectomy is a common practice in western areas of South America. GBC particularly affects women in South America, and represents a significant public health problem. It appears to have peculiarities that pose an urgent need for additional research aimed to discover risk factors, molecular events associated with its development and new treatment options for this lethal disease.

The Asian American family and mental health: implications for child health professionals.

Science.gov (United States)

Jacob, Jeena; Gray, Barbara; Johnson, Ann

2013-01-01

The Asian American community has grown significantly in the United States during recent decades. The culture of their countries of origin as well as the society in which they currently live plays a pivotal role in their reaction to mental health and illness. Mental health issues are increasingly evident in Asian American communities. The need for the delivery of culturally competent health care and mental health services is paramount. A culturally competent framework that includes the use of a cultural competence model for practice can guide the health care provider in the recognition of problems, particularly in the children of Asian American families.

2016-09-01

In South Carolina, the co-occurrence of diabetes mellitus (DM) and breast cancer (BrCA) is much more prevalent among African American populations than among European American populations. The underlying relationship between diabetes and breast cancer may influence breast cancer survival. The purpose of this investigation is to examine the effect of diabetes on developing breast cancer and to reduce racial disparities in breast cancer outcomes. Study participants included women of European American (EA) and African American (AA) ethnicity from both the Medicaid ICD-9 designations and the South Carolina Central Cancer Registry (SCCCR). A historical prospective cohort design was used to determine the risk of developing breast cancer among women of different ethnicities with and without DM. The chi-square test was used to determine the significance of the association; the logistic model was used to assess the relationship between breast cancer and other factors among EA and AA women. Menopause may have protective properties for AA compared to EA women. AA women have twice the odds of not surviving from each breast cancer stage compared to EA women with respect to their breast cancer stage. Adherence to diabetes medication may contribute to lower breast cancer death in EA. This study illustrates the discrepancy between EA and AA women in terms of breast cancer survival. AA women bear a higher disease burden than EA women. To create ethnic-appropriate public health policies, it is imperative that we understand the effect of comorbidities on breast cancer and how we can prevent them from occurring.

Mitochondrial control region haplotypes of the South American sea lion Otaria flavescens (Shaw, 1800).

The South American sea lion, Otaria flavescens, is widely distributed along the Pacific and Atlantic coasts of South America. However, along the Brazilian coast, there are only two nonbreeding sites for the species (Refúgio de Vida Silvestre da Ilha dos Lobos and Refúgio de Vida Silvestre do Molhe Leste da Barra do Rio Grande), both in Southern Brazil. In this region, the species is continuously under the effect of anthropic activities, mainly those related to environmental contamination with organic and inorganic chemicals and fishery interactions. This paper reports, for the first time, the genetic diversity of O. flavescens found along the Southern Brazilian coast. A 287-bp fragment of the mitochondrial DNA control region (D-loop) was analyzed. Seven novel haplotypes were found in 56 individuals (OFA1-OFA7), with OFA1 being the most frequent (47.54%). Nucleotide diversity was moderate (π = 0.62%) and haplotype diversity was relatively low (67%). Furthermore, the median joining network analysis indicated that Brazilian haplotypes formed a reciprocal monophyletic clade when compared to the haplotypes from the Peruvian population on the Pacific coast. These two populations do not share haplotypes and may have become isolated some time back. Further genetic studies covering the entire species distribution are necessary to better understand the biological implications of the results reported here for the management and conservation of South American sea lions.

2016-01-01

Objectives This study examined how cultural orientations influence youth perception of family processes in Korean American families, and how these family processes in turn predict depressive symptoms and antisocial behaviors among youth. Family processes were examined separately for maternal and paternal variables. Methods This study used survey data from Korean American families living in the Midwest (256 youth and their parents) across two time periods, spanned over a year. At the time of the first interview, the average age of youth was 13 (SD=1.00). Using Structural Equation Modeling, this study tested the hypothesized associations concurrently, longitudinally, and accounting for earlier outcomes. Results and Conclusion Results show that identity and behavioral enculturation in one’s heritage culture are predictors of bonding with parents, which is notably protective for youth. The results highlight the critical effect of enculturation in enhancing youth perception of the parent-child relationship. Behavioral acculturation to mainstream culture, in contrast, predicts youth problems, although the effect may not necessarily always be via family processes. Similarly, Korean and English language proficiencies predict fewer youth problems, but not always by way of family processes. A few differences emerged across maternal and paternal variables, although there was much commonality in the hypothesized relationships. PMID:27429061

Family medicine training in sub-Saharan Africa: South–South cooperation in the Primafamed project as strategy for development

Science.gov (United States)

Flinkenflögel, Maaike; Essuman, Akye; Chege, Patrick; Ayankogbe, Olayinka; De Maeseneer, Jan

2014-01-01

Background. Health-care systems based on primary health care (PHC) are more equitable and cost effective. Family medicine trains medical doctors in comprehensive PHC with knowledge and skills that are needed to increase quality of care. Family medicine is a relatively new specialty in sub-Saharan Africa. Objective. To explore the extent to which the Primafamed South–South cooperative project contributed to the development of family medicine in sub-Saharan Africa. Methods. The Primafamed (Primary Health Care and Family Medicine Education) project worked together with 10 partner universities in sub-Saharan Africa to develop family medicine training programmes over a period of 2.5 years. A SWOT (strengths, weaknesses, opportunities and threats) analysis was done and the training development from 2008 to 2010 in the different partner universities was analysed. Results. During the 2.5 years of the Primafamed project, all partner universities made progress in the development of their family medicine training programmes. The SWOT analysis showed that at both national and international levels, the time is ripe to train medical doctors in family medicine and to integrate the specialty into health-care systems, although many barriers, including little awareness, lack of funding, low support from other specialists and reserved support from policymakers, are still present. Conclusions. Family medicine can play an important role in health-care systems in sub-Saharan Africa; however, developing a new discipline is challenging. Advocacy, local ownership, action research and support from governments are necessary to develop family medicine and increase its impact. The Primafamed project showed that development of sustainable family medicine training programmes is a feasible but slow process. The South–South cooperation between the ten partners and the South African departments of family medicine strengthened confidence at both national and international levels. PMID:24857843

Diversification in the Andes: age and origins of South American Heliotropium lineages (Heliotropiaceae, Boraginales).

Luebert, Federico; Hilger, Hartmut H; Weigend, Maximilian

2011-10-01

The uplift of the Andes was a major factor for plant diversification in South America and had significant effects on the climatic patterns at the continental scale. It was crucial for the formation of the arid environments in south-eastern and western South America. However, both the timing of the major stages of the Andean uplift and the onset of aridity in western South America remain controversial. In this paper we examine the hypothesis that the Andean South American groups of Heliotropium originated and diversified in response to Andean orogeny during the late Miocene and a the subsequent development of aridity. To this end, we estimate divergence times and likely biogeographical origins of the major clades in the phylogeny of Heliotropium, using both Bayesian and likelihood methods. Divergence times of all Andean clades in Heliotropium are estimated to be of late Miocene or Pliocene ages. At least three independent Andean diversification events can be recognized within Heliotropium. Timing of the diversification in the Andean lineages Heliotropium sects.Heliothamnus, Cochranea, Heliotrophytum, Hypsogenia, Plagiomeris, Platygyne clearly correspond to a rapid, late Miocene uplift of the Andes and a Pliocene development of arid environments in South America.

Second-generation bioethanol from industrial wood waste of South American species

Directory of Open Access Journals (Sweden)

María E. Vallejos

2017-09-01

Full Text Available There is a global interest in replacing fossil fuels with renewable sources of energy. The present review evaluates the significance of South-American wood industrial wastes for bioethanol production. Four countries have been chosen for this review, i.e., Argentina, Brazil, Chile, and Uruguay, based on their current or potential forestry industry. It should be noted that although Brazil has a global bioethanol market share of 25%, its production is mainly first-generation bioethanol from sugarcane. The situation in the other countries is even worse, in spite of the fact that they have regulatory frameworks in place already allowing the substitution of a percentage of gasoline by ethanol. Pines and eucalyptus are the usually forested plants in these countries, and their industrial wastes, as chips and sawdust, could serve as promising raw materials to produce second-generation bioethanol in the context of a forest biorefinery. The process to convert woody biomass involves three stages: pretreatment, enzymatic saccharification, and fermentation. The operational conditions of the pretreatment method used are generally defined according to the physical and chemical characteristics of the raw materials and subsequently determine the characteristics of the treated substrates. This article also reviews and discusses the available pretreatment technologies for eucalyptus and pines applicable to South-American industrial wood wastes, their enzymatic hydrolysis yields, and the feasibility of implementing such processes in the mentioned countries in the frame of a biorefinery.

2006-01-01

Full Text Available Studies on availability of suitable and economic diets for adults and larvae of the South American fruit fly Anastrepha fraterculus (Wiedemann, 1830 were carried out at the Entomology Unit of the FAO/IAEA Agriculture and Biotechnology Laboratories in Seibersdorf, Austria with the aim to find the best diets to fit in a large scale mass rearing production. The best diet for adult was the combination of Hydrolysate Corn Protein + Yeast Hydrolysate Enzymatic + Sugar (3:1:3. This diet resulted in the highest numbers of egg/female/day, spermatozoid in the spermathecae, percentages of egg hatch, the lowest mortality rate of adults and the highest average mating duration compared with the standard adult diet based on Yeast Hydrolysate Enzymatic + Sugar (1:3. Among eleven larval diets tested, diets based on sugarcane and sugarbeet bagases plus 7% brewer yeast, 8% sugar, 0.2% sodium benzoate, 0.8% of hydrochloric acid and 60% water (adjusted, yielded the highest percentages of egg hatching, pupal recovery, pupal weight and adult emergence. There was no statistical difference with the standard larval diet based on wheat germ 3%, corncob 15%, corn flower 8%, brewer yeast 6%, sugar 8%, sodium benzoate 0.23%, hydrochloric acid 0.63%, nipagin 0.14% and water 59% (adjusted. The significant performance of these adult and larval diets open discussion for future researches on improvement of rearing techniques required for the establishment of sterile insect technique (SIT program focused on the South American fruit fly.

The changing European family: lessons for the American reader.

Science.gov (United States)

Cherlin, A; Furstenberg Ff

1988-09-01

The 7 chapters in this journal discuss the European family, including families in Britain, the Federal Republic of Germany, France, the German Democratic Republic, Italy, and Sweden. The authors feel that observers in the US sometimes resort to peculiarly American explanations (the budget deficit, changes in welfare benefits) to account for recent trends in marriage and fertility. The articles in this issue demonstrate that the pattern of post-WWII family change has been generally similar in North America, Western Europe, and even part of Eastern Europe, suggesting that more global rather than particular national explanations need to be sought. The post-WWII years can be divided into 2 periods: 1) the period from 1945 to 1965 that brought the unexpected marriage rush and baby boom, and 2) the period from 1965 to the present that brought a reversal of those trends in the form of later marriage, a great increase in nonmarital cohabitation, a large rise in divorce, and a sharp fall in fertility to below the replacement level. The similarity of these large-scale trends in North America and Western Europe is striking. The US is most like Britain and, beyond Europe, Canada, and Australia, suggesting that influence of the common culture of the English-speaking Western world. Yet the US has, and probably always has had, higher rates of fertility, marriage, and divorce than most Western European nations. The proportion of single-parent families is unusually large, even though some nations such as Sweden and East Germany have higher proportions of births to unmarried but cohabiting women. The level of cohabitation in the US, although greatly increased, is still moderate by European standards. Concern over the burden of government support for the elderly already has prompted changes in the Social Security program. The ability to support programs for children and for poor families is being questioned, even though the level of government support for the family is relatively low

Everyday (inequality at home: complex constructions of gender in South African families

Directory of Open Access Journals (Sweden)

Rebecca Helman

2016-06-01

Full Text Available Background: High rates of violence and HIV have been documented within the South African context. Constructions of masculinity and femininity that position men as dominant and highly sexually active and women as subordinate and acquiescent have been found to contribute towards gender inequality. This inequality is in turn related to negative health consequences, specifically violence against women, children, and other men, as well as sexual risk. Within this context it becomes important to explore how problematic constructions of gender are being (reproduced and how these constructions are being challenged. Families have been identified as key sites in which gender is both constructed and enacted on a daily basis and it is within this space that children are first exposed to notions of gender. Objective: This article draws from a study that was intended to expand on the limited understandings of the ways in which gender (inequality is constructed and conveyed within the context of South African families on an everyday basis. Design: Children and parents in 18 families from a range of different material and cultural backgrounds were interviewed about the meanings and practices of gender within their homes. Data were analysed using a Foucauldian discourse analysis. Results: The data reveal how problematic constructions of masculinity and femininity are (reproduced but also challenged within a range of different families. Gender and gender (inequality are therefore routinely accomplished in complex ways. Conclusions: These findings have important implications for promoting gender equality and therefore for disrupting violence and sexual risk as gendered health issues.

Mexican American youth are at greater risk of school failure than their peers. To identify factors that may contribute to academic success in this population, this study examined the prospective relationships from 5th grade to 7th grade of family (i.e., human capital [a parent with at least a high school education], residential stability, academically and occupationally positive family role models, and family structure) and individual characteristics (i.e., externalizing symptoms, bilingualism, gender, and immigrant status) to the academic performance of 749 Mexican American early adolescents (average age = 10.4 years and 48.7% were girls in 5th grade) from economically and culturally diverse families as these youth made the transition to junior high school. Results indicated that while controlling for prior academic performance, human capital and positive family role models assessed when adolescents were in in 5th grade positively related to academic performance in 7th grade. Further, being a girl also was related to greater 7th grade academic success, whereas externalizing symptoms were negatively related to 7th grade academic performance. No other variables in the model were significantly and prospectively related to 7th grade academic performance. Implications for future research and interventions are discussed. PMID:21863379

Increased susceptibility to cleft lip, with or without cleft palate (CL±P) has been observed in South America, as related to Amerindian ancestry, using epidemiological data, uniparental markers, and blood groups. In this study, it was evaluated whether this increased risk remains when Amerindian ancestry is estimated using autosomal markers and considered in the predictive model. Ancestry was estimated through genotyping 62 insertion and deletion (INDEL) markers in sample sets of patients with CL±P, patients with cleft palate (CP), and controls, from Patagonia in southern Argentina and Belém in northern Brazil. The Amerindian ancestry in patients from Patagonia with CL±P was greater than in controls although it did not reach statistical significance. The European ancestry in patients with CL±P from Belém and in patients with CP from Belém and Patagonia was higher than in controls and statistically significant for patients with CP who were from Belém. This high contribution of European genetic ancestry among patients with CP who were from Belém has not been previously observed in American populations. Our results do not corroborate the currently accepted risks for CL±P and CP estimated by epidemiological studies in the North American populations and probably reflect the higher admixture found in South American ethnic groups when compared with the same ethnic groups from the North American populations. © 2016 Eur J Oral Sci.

Laje, Rodrigo; Mindlin, Gabriel B.

2003-12-01

The South American Hornero (Furnarius rufus) is a suboscine bird widely known for its mud-made, oven-looking nest. Beyond their architectural skills, the male and female Horneros sing in highly structured duets. The analysis of field recordings reported in this work reveals that as the male increases the note production rate the female responds by switching to different locking states: the ones predicted by the theory of nonlinear forced oscillators. This gives the duet a most appealing rhythm, and unveils the nonlinear nature of the underlying brain activity needed to generate the song.

This article proposes explanations for the transformation of American families over the past two centuries. I describe the impact on families of the rise of male wage labor beginning in the nineteenth century and the rise of female wage labor in the twentieth century. I then examine the effects of decline in wage labor opportunities for young men and women during the past four decades. I present new estimates of a precipitous decline in the relative income of young men and assess its implications for the decline for marriage. Finally, I discuss explanations for the deterioration of economic opportunity and speculate on the impact of technological change on the future of work and families. PMID:26511502

2016-08-01

To identify barriers and motivators for reducing secondhand smoke exposure (SHSe) for families of African-American, low-income, urban children. Audiotaped intervention sessions of 52 African-American caregivers of Head Start children who reported being a smoker and/or had at least one smoker in the home were randomly sampled from a larger trial examining the effectiveness of a motivational-interviewing intervention in reducing child's SHSe. Counseling sessions were qualitatively coded to identify barriers and motivators to implementing a home smoking ban or quitting smoking. African-American families identified several themes that were either or both barriers and motivators for SHSe reduction, including: asking others not to smoke, other family living in the home, neighborhood safety, absence of childcare, cost/availability of cessation tools, physician support and prevention of health problems. Urban, low-income African-American families face numerous barriers to reducing SHSe. Families were able to identify many motivators for reducing SHSe, suggesting an awareness of the importance for SHSe reduction but uncertainty in their confidence to change behaviors. Counseling should include tailoring to be most effective in supporting health behavior change. Greater emphasis on motivators is needed, such as low-cost/free cessation tools, engagement from physicians and greater involvement of extended family members. © The Author 2016.

Prosopis pod production: comparison of North American, South American, Hawaiin, and African germplasm in young plantations

Energy Technology Data Exchange (ETDEWEB)

Felker, P.; Clark, P.R.; Osborn, J.F.; Cannell, G.H.

Prosopis pod production was compared in 3 field trials in southern California, i.e., a typical orchard planting, an irrigation trial, and a heat/drought stress trial. Thirteen species representing North American, South American, Hawaiian, and African germplasm were evaluated. Hawaiian and African accessions were eliminated from the irrigation trial by a minus 5/sup 0/C temperature. The most productive pod producers were P. velutina accessions from southern Arizona. In the fifth season, 5 trees of the most productive accession, i.e., P. velutina 32 had a mean pod production of 7.2 kg/tree with a range of 3.2-12.2 kg/tree. P. chilensis and P. alba trees of the same age were much larger but had less pod production. Trees in the driest irrigation treatment had the greatest pod production. Pod production estimates of 3000-4000 kg/ha were obtained in the dry irrigation treatment by P. velutina 20 which received 370 mm rainfall in the year preceding harvest. 32 references, 1 figure, 6 tables.

Native South American genetic structure and prehistory inferred from hierarchical modeling of mtDNA.

Genetic diversity in Native South Americans forms a complex pattern at both the continental and local levels. In comparing the West to the East, there is more variation within groups and smaller genetic distances between groups. From this pattern, researchers have proposed that there is more variation in the West and that a larger, more genetically diverse, founding population entered the West than the East. Here, we question this characterization of South American genetic variation and its interpretation. Our concern arises because others have inferred regional variation from the mean variation within local populations without taking into account the variation among local populations within the same region. This failure produces a biased view of the actual variation in the East. In this study, we analyze the mitochondrial DNA sequence between positions 16040 and 16322 of the Cambridge reference sequence. Our sample represents a total of 886 people from 27 indigenous populations from South (22), Central (3), and North America (2). The basic unit of our analyses is nucleotide identity by descent, which is easily modeled and proportional to nucleotide diversity. We use a forward modeling strategy to fit a series of nested models to identity by descent within and between all pairs of local populations. This method provides estimates of identity by descent at different levels of population hierarchy without assuming homogeneity within populations, regions, or continents. Our main discovery is that Eastern South America harbors more genetic variation than has been recognized. We find no evidence that there is increased identity by descent in the East relative to the total for South America. By contrast, we discovered that populations in the Western region, as a group, harbor more identity by descent than has been previously recognized, despite the fact that average identity by descent within groups is lower. In this light, there is no need to postulate separate founding

The Sewol ferry incident on April 16, 2014 in South Korea claimed the lives of 304 individuals, including about 250 high school students on a school trip. The majority of South Korean citizens were watching live updates on the capsized Sewol ferry, anxiously watching on TV how the vessel fully sunk over time. They were desperately hoping for the rescue of the survivors inside. However, their anxiety had become shock, anger, and helplessness, and the disaster has become a daunting, collective trauma, not just to the victims and their families, but also to the citizens who were exposed only through the media. In this study, we interviewed victims' families two years after the incident. We explored how they have experienced changes in their social relationships. We conducted semi-structured interviews of 54 family members of the student victims. We qualitatively examined the data applying a thematic analysis. Changes in their social relationships were largely divided into the relationships in the proximal environment and the relationships in distal environments. The former included subcategories such as immediate family, coworkers, friends, relatives, survived students and their parents, and concepts corresponding to each subcategory. The latter involved subcategories such as neighbors, other citizens, the victims' family committee, government, and society, and concepts subject to each subcategory. Based on these findings, rehabilitation plans for trauma victims and their families should take into account the significant changes in their social relationships and the further consequences of those changes.

2010-09-01

Full Text Available The South American sea lion, Otaria flavescens, is widely distributed along the Pacific and Atlantic coasts of South America. However, along the Brazilian coast, there are only two nonbreeding sites for the species (Refúgio de Vida Silvestre da Ilha dos Lobos and Refúgio de Vida Silvestre do Molhe Leste da Barra do Rio Grande, both in Southern Brazil. In this region, the species is continuously under the effect of anthropic activities, mainly those related to environmental contamination with organic and inorganic chemicals and fishery interactions. This paper reports, for the first time, the genetic diversity of O. flavescens found along the Southern Brazilian coast. A 287-bp fragment of the mitochondrial DNA control region (D-loop was analyzed. Seven novel haplotypes were found in 56 individuals (OFA1-OFA7, with OFA1 being the most frequent (47.54%. Nucleotide diversity was moderate (π = 0.62% and haplotype diversity was relatively low (67%. Furthermore, the median joining network analysis indicated that Brazilian haplotypes formed a reciprocal monophyletic clade when compared to the haplotypes from the Peruvian population on the Pacific coast. These two populations do not share haplotypes and may have become isolated some time back. Further genetic studies covering the entire species distribution are necessary to better understand the biological implications of the results reported here for the management and conservation of South American sea lions.

Full Text Available Abstract Background Body fat mass distribution and deposition are determined by multiple environmental and genetic factors. Obesity is associated with insulin resistance, hyperinsulinemia, and type 2 diabetes. We previously identified evidence for genotype-by-diabetes interaction on obesity traits in Strong Heart Family Study (SHFS participants. To localize these genetic effects, we conducted genome-wide linkage scans of obesity traits in individuals with and without type 2 diabetes, and in the combined sample while modeling interaction with diabetes using maximum likelihood methods (SOLAR 2.1.4. Methods SHFS recruited American Indians from Arizona, North and South Dakota, and Oklahoma. Anthropometric measures and diabetes status were obtained during a clinic visit. Marker allele frequencies were derived using maximum likelihood methods estimated from all individuals and multipoint identity by descent sharing was estimated using Loki. We used variance component linkage analysis to localize quantitative trait loci (QTLs influencing obesity traits. We tested for evidence of additive and QTL-specific genotype-by-diabetes interactions using the regions identified in the diabetes-stratified analyses. Results Among 245 diabetic and 704 non-diabetic American Indian individuals, we detected significant additive gene-by-diabetes interaction for weight and BMI (P P Conclusion These results suggest distinct genetic effects on body mass in individuals with diabetes compared to those without diabetes, and a possible role for one or more genes on chromosome 1 in the pathogenesis of obesity.

South American regional ionospheric maps computed by GESA: A pilot service in the framework of SIRGAS

Science.gov (United States)

Brunini, C.; Meza, A.; Gende, M.; Azpilicueta, F.

2008-08-01

SIRGAS (Geocentric Reference Frame for the Americas) is an international enterprise of the geodetic community that aims to realize the Terrestrial Reference Frame in the America's countries. In order to fulfill this commitment, SIRGAS manages a network of continuously operational GNSS receivers totalling around one hundred sites in the Caribbean, Central, and South American region. Although the network was not planed for ionospheric studies, its potential to be used for such a purpose was recently recognized and SIRGAS started a pilot experiment devoted to establish a regular service for computing and releasing regional vertical TEC (vTEC) maps based on GNSS data. Since July, 2005, the GESA (Geodesia Espacial y Aeronomía) laboratory belonging to the Facultad de Ciencias Astronómicas y Geofísicas of the Universidad Nacional de La Plata computes hourly maps of vertical Total Electron Content (vTEC) in the framework of the SIRGAS pilot experiment. These maps exploit all the GNSS data available in the South American region and are computed with the LPIM (La Plata Ionospheric Model). LPIM implements a de-biasing procedure that improves data calibration in relation to other procedures commonly used for such purposes. After calibration, slant TEC measurements are converted to vertical and mapped using local-time and modip latitude. The use of modip latitude smoothed the spatial variability of vTEC, especially in the South American low latitude region and hence allows for a better vTEC interpolation. This contribution summarizes the results obtained by GESA in the framework of the SIRGAS pilot experiment.

Kang, Young-Hee

2013-01-01

Using the Korean Labor and Income Panel Study (KLIPS), I investigated the impact of family-friendly policies (FFPs) on job satisfaction and organizational commitment in the private sector of South Korea. Paid leave, childcare leave, and support for housing are positively related to both job satisfaction and organizational commitment. Sick leave is positively related to organizational commitment. However, subsidized family event cost is a marginally significant predictor of job satisfaction and organizational commitment. In addition, the relationships between subsidized childcare cost and employee attitudes were not supported. Implications and suggestions for future research are discussed.

Although many glass-bearing horizons can be found in South American volcanic complexes or sedimentary series, only a relatively few tephra and obsidian-bearing volcanic fields have been studied using the fission-track (FT) dating method. Among them, the volcanics located in the Sierra de Guamani (east of Quito, Ecuador) were studied by several authors. Based upon their ages, obsidians group into three clusters: (1) very young obsidians, {approx}0.2Ma old (2) intermediate-age obsidians, {approx}0.4-{approx}0.8Ma old, and (3) older obsidians, {approx}1.4-{approx}1.6Ma old. The FT method is also an efficient alternative technique for identification of the sources of prehistoric obsidian artefacts. Provenance studies carried out in South America have shown that the Sierra de Guamani obsidian occurrences were important sources of raw material for tool making during pre-Columbian times. Glasses originated from these sources were identified in sites distributed over relatively wide areas of Ecuador and Colombia. Only a few systematic studies on obsidians in other sectors were carried out. Nevertheless, very singular glasses have been recognised in South America, such as Macusanite (Peru) and obsidian Quiron (Argentina), which are being proposed as additional reference materials for FT dating. Analyses of tephra beds interstratified with sedimentary deposits revealed the performance of FT dating in tephrochronological studies. A remarkable example is the famous deposit outcropping at Farola Monte Hermoso, near Bahia Blanca (Buenos Aires Province), described for the first time by the middle of the 19th century by Charles Darwin. Considering the large number of volcanic glasses that were recognised in volcanic complexes and in sedimentary series, South America is a very promising region for the application of FT dating. The examples given above show that this technique may yield important results in different disciplinary fields.

IAEA Helps Remove Highly Radioactive Material from Five South American Countries

International Nuclear Information System (INIS)

2018-01-01

The International Atomic Energy Agency (IAEA) has helped remove 27 disused highly radioactive sources from five South American countries in a significant step forward for nuclear safety and security in the region. It was the largest such project ever facilitated by the IAEA. The material, mainly used for medical purposes such as treating cancer and sterilizing instruments, was transported to Germany and the United States for recycling. Canada, where some of the sources were manufactured, funded the project upon requests for IAEA support from Bolivia, Ecuador, Paraguay, Peru and Uruguay. The sealed Cobalt-60 and Caesium-137 sources pose safety and security risks when no longer in use, according to Raja Adnan, Director of the IAEA’s Division of Nuclear Security. “The removal of this large number of radioactive sources has significantly reduced those risks in the five countries,” Adnan said. In recent years, the IAEA has assisted Bosnia and Herzegovina, Cameroon, Costa Rica, Honduras, Lebanon, Morocco, Tunisia and Uzbekistan in the removal of disused sources. The South American operation was the largest the IAEA has so far coordinated in terms of both the number of highly radioactive sources and countries involved. While nuclear safety and security are national responsibilities, the IAEA helps Member States upon request to meet these responsibilities through training, technical advice, peer reviews and other advisory services. Such efforts may include support for Member States in implementing the safe and cost-effective recovery, conditioning, storage, disposal or transportation of disused sealed radioactive sources (DSRS).

Family, peer, and neighborhood influences on academic achievement among African-American adolescents: one-year prospective effects.

1996-06-01

Using a 1-year prospective design, this study examined the influence of family status variables (family income, parental education, family structure), parenting variables (maternal support and restrictive control), peer support, and neighborhood risk on the school performance of 120 African American junior high school students. In addition to main effects of these variables, neighborhood risk was examined as a moderator of the effects of parenting and peer support. Family status variables were not predictive of adolescent school performance as indexed by self-reported grade point average. Maternal support at Time 1 was prospectively related to adolescent grades at Time 2. Neighborhood risk was related to lower grades, while peer support predicted better grades in the prospective analyses. Neighborhood risk also moderated the effects of maternal restrictive control and peer support on adolescent grades in prospective analyses. These findings highlight the importance of an ecological approach to the problem of academic underachievement within the African American Community.

Despite the growing need for organ donation among Asian Americans, studies suggest that they are reluctant to donate. To examine the association of attitudes and knowledge about organ donation and transplantation with willingness to donate and willingness to engage in family discussion about organ donation among Asian American adolescents. A cross-sectional study. The Big Island of Hawaii. Self-identified Asian American adolescents (Japanese, Chinese, Filipino, Korean), ages 16 to 17 years old, and each adolescent's parent or guardian. Asian American adolescents provided demographic information and completed the Modified Organ Donation Attitude Survey, the Organ Donation and Transplantation Knowledge Survey, and the Suinn-Lew Asian Self-Identity Acculturation Scale. A parent or guardian also provided demographic information. Linear regression analyses were used to examine the associations with willingness to donate and to engage in family discussion about organ discussion. Willingness to donate was associated with positive knowledge related to general aspects about organ donation and cultural limitations in receiving an organ transplant, a high level of acculturation, and a low level of negative attitudes (R2 = 0.402, F = 18.86, P = .005). Asian American adolescents with approving or positive attitudes were likely to engage in family discussion about organ donation (R2 = 0.195, F = 27.93, P = .005). To reinforce and maintain high levels of knowledge and positive attitudes, organ donation education is most likely needed in high schools.

Grandparent caregiving among rural African Americans in a community in the American South: challenges to health and wellbeing.

Clottey, Emmanuel N; Scott, Alison J; Alfonso, Moya L

2015-01-01

An increasing number of grandparents in rural USA are serving as primary caregivers for their grandchildren because of parental incarceration, addiction, joblessness, or illness. Low-income, African American women from the South are overrepresented in this growing population. There is a paucity of research exploring the challenges faced by rural grandparent caregivers, and past studies have not explicitly addressed the potential consequences of rural grandparent caregiving for health. The purpose of this qualitative study was to explore grandparent caregiving among rural, low-income, African American grandmothers in a community in the American South, and to identify challenges to health that arose in that context. McLeroy's social ecological model (SEM) was used to examine these challenges at multiple levels of influence. This qualitative interview-based study was conducted in a high-poverty community in rural Georgia. In-depth interviews were conducted with African American grandparent caregivers and key informants from local community-based organizations. A key informant assisted in identifying initial interview participants, and then snowball sampling was used to recruit additional participants. Interview questions were grouped under five domains (intrapersonal, interpersonal, community, organizational, and policy), according to the levels of the SEM. Iterative content analysis of interview transcripts was utilized. Transcripts were coded to identify text segments related to each domain of the SEM, which were grouped together for analysis by domain. Reflexive memo-writing aided in development of themes, and data quality was assessed using Lincoln and Guba's trustworthiness criteria. Rural African American grandparent caregivers faced a range of challenges to health. Direct physical challenges included chronic pain that interfered with sleep and daily functioning, mobility issues exacerbated by child care, and the pressure of managing their own medical conditions

Family Ties and Young Fathers’ Engagement in Cape Town, South Africa

Clark, Shelley; Cotton, Cassandra; Marteleto, Leticia J.

2015-01-01

Young South African fathers are often engaged in their children’s lives even if they do not live together. Using longitudinal data on children (n = 1,209) from the Cape Town area, the authors show that although only 26% of young fathers live with their children, 66% of nonresidential fathers maintain regular contact, and 61% provide financial support. The father–child relationship, however, is embedded in broader family ties. The type of father–mother relationship is strongly associated with whether fathers coreside with their children, but not with fathers’ contact with nonresidential children. Close mother and maternal grandmother bonds reduce the likelihood that fathers live with their children, whereas close ties between fathers and paternal grandmothers increase the chance that fathers visit nonresidential children. Family ties do not affect fathers’ financial contributions, which are driven by men’s current economic situation. These findings illustrate that father–child relationships are best understood in the context of interacting family systems. PMID:25774066

Objective We examine disparities in birth weight and gestational age by ethnic ancestry in 2000–2011 in eight South American countries. Methods The sample included 60480 singleton live-births. Regression models were estimated to evaluate differences in birth outcomes by ethnic ancestry controlling for time trends. Results Significant disparities were found in seven countries. In four countries – Brazil, Ecuador, Uruguay, and Venezuela – we found significant disparities in both low birth weight and preterm birth. Disparities in preterm birth alone were observed in Argentina, Bolivia, and Colombia. Several differences in continuous birth weight, gestational age, and fetal growth rate were also observed. There were no systematic patterns of disparities between the evaluated ethnic ancestry groups across the study countries, in that no racial/ethnic group consistently had the best or worst outcomes in all countries. Conclusions Racial/ethnic disparities in infant health are common in several South American countries. Differences across countries suggest that racial/ethnic disparities are driven by social and economic mechanisms. Researchers and policymakers should acknowledge these disparities and develop research and policy programs to effectively target them. PMID:25542227

Change in the foraging strategy of female South American sea lions (Carnivora: Pinnipedia after parturition

Directory of Open Access Journals (Sweden)

Massimiliano Drago

2010-08-01

Full Text Available This study tests the hypothesis that female South American sea lions shift from off-shore, pelagic prey to coastal, benthic prey after parturition in order to reduce the foraging trip duration and hence the time pups remain unattended on the beach during early lactation. The δ13C and δ15N values of the serum and blood cells of 26 South American sea lion suckling pups from northern Patagonia were used to track the dietary changes of their mothers from late pregnancy to early lactation, after correction for differential isotopic fractionation between tissues. Primary producers and potential prey species were also analysed to establish a baseline for interpreting the stable isotope concentration of serum and blood cells. Isotopic ratios revealed a generalized increase in the consumption of coastal-benthic prey after parturition. Such a generalized post-partum shift will allow females to spend more time on land and look after their pups. The effects of this foraging strategy on the nutritional quality of the female’s diet are discussed.

The goal of the feasibility phase of the Pathways family intervention was to work with families of third-grade American Indian children to reinforce health behaviors being promoted by the curriculum, food service, and physical activity components of this school-based obesity prevention intervention. Family behaviors regarding food choices and physical activity were identified and ranked according to priority by using formative assessment and a literature review of school-based programs that included a family component. The family intervention involved 3 primary strategies designed to create an informed home environment supportive of behavioral change: 1) giving the children “family packs” containing worksheets, interactive assignments, healthful snacks, and low-fat tips and recipes to take home to share with their families; 2) implementing family events at the school to provide a fun atmosphere in which health education concepts could be introduced and reinforced; and 3) forming school-based family advisory councils composed of family members and community volunteers who provided feedback on Pathways strategies, helped negotiate barriers, and explored ideas for continued family participation. For strategy 2, a kick-off Family Fun Night provided a series of learning booths that presented the healthful behaviors taught by Pathways. At an end-of-year Family Celebration, a healthy meal was served, students demonstrated newly learned Pathways activities, and certificates were presented in recognition of completion of the Pathways curriculum. Based on evaluation forms and attendance rosters, strategies 1 and 2 were more easily implemented and better received than strategy 3. Implications for developing family involvement strategies for intervention programs are discussed. PMID:10195606

The South American fruit fly, Anastrepha fraterculus (Wied.); advances in artificial rearing, taxonomic status and biological studies. Proceedings of a workshop

Energy Technology Data Exchange (ETDEWEB)

1999-01-01

One of the fruit flies of major concern, because of its economic and quarantine importance in the Americas, is the exotic Mediterranean fruit fly, Ceratitis capitata, which is established throughout the Central and South American countries, excluding Chile. Chile, Mexico and the USA have conducted multi-million dollar campaigns to prevent the establishment of this and other exotic fruit flies in their respective territories, in support of the development of important fruit production and export industries. Other important fruit fly species, which are native to the American continent, are those of the genus Anastrepha. In this group, of most economic importance are A. obliqua and A. ludens for Mexico and some Central American countries and A. fraterculus and A. obliqua for South America.

One of the fruit flies of major concern, because of its economic and quarantine importance in the Americas, is the exotic Mediterranean fruit fly, Ceratitis capitata, which is established throughout the Central and South American countries, excluding Chile. Chile, Mexico and the USA have conducted multi-million dollar campaigns to prevent the establishment of this and other exotic fruit flies in their respective territories, in support of the development of important fruit production and export industries. Other important fruit fly species, which are native to the American continent, are those of the genus Anastrepha. In this group, of most economic importance are A. obliqua and A. ludens for Mexico and some Central American countries and A. fraterculus and A. obliqua for South America. In this publication, attention is focused on A. fraterculus, the South American fruit fly. This species, as it is presently recognized, occurs from Mexico to Argentina and is reported from approximately 80 host plants, including commercial fruits of economic importance, such as mango, citrus, guava, apple and coffee. As A. fraterculus if considered to be of high economic and quarantine importance in many countries in South America, it is justifiable to recommend and promote the implementation of activities to strengthen knowledge of the species and develop techniques for its control and/or eradication. The development of sterile insect technique (SIT) and other biological control methods are very encouraging alternatives, as can be seen from examples in Mexico and the USA, where these approaches are in use against A. ludens and A. obliqua

in a Family of South Indian Descent

Directory of Open Access Journals (Sweden)

Muthiah Subramanian

Full Text Available Inherited channelopathies are a heterogeneous group of disorders resulting from dysfunction of ion channels in cellular membranes. They may manifest as diseases affecting skeletal muscle contraction, the conduction system of the heart, nervous system function, and vision syndromes. We describe a family of South Indian descent with hypokalemic periodic paralysis in which four members also have idiopathic generalized epilepsy. Hypokalemic periodic paralysis is a genetically heterogeneous channelopathy that has been linked to mutations in genes encoding three ion channels CACNIAS, SCN4A, and KCNJ2 predominantly. Although data on specific gene in idiopathic generalized epilepsy is relatively scarce, mutations of voltage gated sodium channel subunit genes (CACNB4 and nonsense mutations in voltage gated calcium channels (CACNA1A have been linked to idiopathic generalized epilepsy in two families. We speculate that gene mutations altering the ability of the beta subunit to interact with the alpha subunit of the CaV1.1 channel and mutations in the pore-forming potassium channel subunit may be possible explanations for the combined manifestation of both diseases. Functional analysis of voltage gated calcium channel and other ion channels mutations may provide additional support and insight for the causal role of these mutations. The understanding of mutations in ion-channel genes will lead to improved diagnosis and treatment of such inherited channelopathies.

2013-07-01

This study was conducted to examine under what situation (i.e., when individuals used more or less family support) and for whom (i.e., those with high or low self-esteem) perceived racial discrimination would or would not have a significant positive association with psychological distress. A total of 95 Asian American male college students completed an online survey. A hierarchical regression analysis indicated a significant 3-way interaction of family support, self-esteem, and perceived racial discrimination in predicting psychological distress after controlling for perceived general stress. A simple effect analysis was used to explore the nature of the interaction. When Asian American male college students used more family support to cope with racial discrimination, the association between perceived racial discrimination and psychological distress was not significant for those with high or low self-esteem. The result from the simple interaction indicated that, when more family support was used, the 2 slopes for high and low self-esteem were not significantly different from each other. Conversely, when they used less family support, the association between perceived racial discrimination and psychological distress was not significant for those with high self-esteem, but was significantly positive for those with low self-esteem. The result from the simple interaction indicated that, when less family support was used, the slopes for high and low self-esteem were significantly different. The result suggested that low use of family support may put these male students with low self-esteem at risk for psychological distress. Limitations, future research directions, and clinical implications were discussed. PsycINFO Database Record (c) 2013 APA, all rights reserved.

Everyday (in)equality at home: complex constructions of gender in South African families

Science.gov (United States)

Helman, Rebecca; Ratele, Kopano

2016-01-01

Background High rates of violence and HIV have been documented within the South African context. Constructions of masculinity and femininity that position men as dominant and highly sexually active and women as subordinate and acquiescent have been found to contribute towards gender inequality. This inequality is in turn related to negative health consequences, specifically violence against women, children, and other men, as well as sexual risk. Within this context it becomes important to explore how problematic constructions of gender are being (re)produced and how these constructions are being challenged. Families have been identified as key sites in which gender is both constructed and enacted on a daily basis and it is within this space that children are first exposed to notions of gender. Objective This article draws from a study that was intended to expand on the limited understandings of the ways in which gender (in)equality is constructed and conveyed within the context of South African families on an everyday basis. Design Children and parents in 18 families from a range of different material and cultural backgrounds were interviewed about the meanings and practices of gender within their homes. Data were analysed using a Foucauldian discourse analysis. Results The data reveal how problematic constructions of masculinity and femininity are (re)produced but also challenged within a range of different families. Gender and gender (in)equality are therefore routinely accomplished in complex ways. Conclusions These findings have important implications for promoting gender equality and therefore for disrupting violence and sexual risk as gendered health issues. PMID:27293123

Kiang, Lisa; Glatz, Terese; Buchanan, Christy M

2017-12-01

Parents from immigrant backgrounds must deal with normative parenting demands as well as unique challenges associated with acculturation processes. The current study examines the independent and interactive influences of acculturation conflict and cultural parenting self-efficacy (PSE; e.g., parents' confidence in instilling heritage, American, and bicultural values in their children) on perceptions of general parenting competence. Using data from 58 Asian American and 153 Latin American parents of children in grades 6-12, ethnic differences were also explored. Results suggest that lower acculturation conflict is associated with higher perceptions of general parenting competence for both Asian and Latin American parents. Higher cultural PSE is associated with higher perceived general parenting competence for Latino/a parents only. One significant interaction was found, and only for Asian Americans, whereby the negative association between acculturation conflict and perceptions of parenting competence was weaker for those who felt efficacious in transmitting heritage messages. Results are discussed in light of clinical implications and the need for further recognition and study of culturally relevant factors and frameworks among families from immigrant backgrounds. © 2016 Family Process Institute.

Although family and cultural factors have been assumed to play important roles in the career development of Asian Americans, theory-driven research on this topic remains limited. We examined culturally relevant factors that may contribute to Asian Americans' consideration of fields in which they are overrepresented (e.g., science, technology, engineering) and underrepresented (e.g., education, social science). Drawing from social cognitive career theory, a culture-specific, social cognitive model of career interests and choice was tested in Holland's (1997) Investigative (I) and Social (S) themes. A sample of 802 Asian American undergraduates completed measures of family support, self-efficacy, outcome expectations, interest, and career choice consideration in relation to both Holland themes. Two indicators of acculturation/enculturation (adherence to Asian values and generation status in the United States) were also obtained. The model accounted for a substantial amount of variance in Asian American college students' career consideration in both themes. Family support and acculturation played varying roles, depending on the Holland theme. For example, family support was linked to career choice consideration both directly (in the S theme) and indirectly, via other predictors (in both themes). Contrary to expectations, the acculturation variables did not moderate the relation of family support or interest to career consideration in either theme. We discuss the implications of these findings for efforts to understand and facilitate the career development of Asian American college students.

Grint, Nicola; Dugdale, Alexandra

2009-01-01

To compare the brightness of South American camelid venous blood to that of Equidae. Prospective clinical evaluation. Twelve South American camelids (eight llamas, four alpacas), eight horses and ponies (control group). Appropriately sized catheters were placed in the jugular vein of each animal under local anaesthesia. The blood spilt before the catheter was capped was caught on a white tile. A sample of blood was drawn for blood-gas analysis. The brightness of the blood (both on the tile and in the syringe) was matched to a colour chart (1 = darkest red, 8 = brightest red) by a single observer under bright light conditions. Packed cell volume (PCV) and partial pressure of oxygen (PvO(2)) in the blood were also measured on the syringe blood. Normally distributed data were compared using a two tailed t-test, and non-normally distributed data were compared using a Mann-Whitney U-test. Significance was set at p Camelid venous blood was significantly brighter red than that of horses and ponies both on the white tile (p = 0.0003) and in the syringe (p = 0.0001). PCV was significantly lower in camelids (32 +/- 4%) compared with horses (37 +/- 5%). Partial pressure of oxygen values were similar between groups. Jugular venous blood in alpacas and llamas is significantly brighter red than that of horses. Colour should not be used as a sole determinant of venous or arterial catheterization in this species.

Social class and family size as determinants of attributed machismo, femininity, and family planning: a field study in two South American communities.

Science.gov (United States)

Nicassio, P M

1977-12-01

A study was conducted to determine the way in which stereotypes of machismo and femininity are associated with family size and perceptions of family planning. A total of 144 adults, male and female, from a lower class and an upper middle class urban area in Colombia were asked to respond to photographs of Colombian families varying in size and state of completeness. The study illustrated the critical role of sex-role identity and sex-role organization as variables having an effect on fertility. The lower-class respondents described parents in the photographs as significantly more macho or feminine because of their children than the upper-middle-class subjects did. Future research should attempt to measure when this drive to sex-role identity is strongest, i.e., when men and women are most driven to reproduce in order to "prove" themselves. Both lower- and upper-middle-class male groups considered male dominance in marriage to be directly linked with family size. Perceptions of the use of family planning decreased linearly with family size for both social groups, although the lower-class females attributed more family planning to spouses of large families than upper-middle-class females. It is suggested that further research deal with the ways in which constructs of machismo and male dominance vary between the sexes and among socioeconomic groups and the ways in which they impact on fertility.

This study assessed perceived needs for psychological support program for family with victim of child sexual abuse in South Korea. We conducted two separate focus group interviews with five therapists who served child sexual abuse victims and families as well as four mothers of a child sexual abuse victim. Consensual qualitative research analysis revealed four domains: Emotional support for parents, psychoeducation, family therapy, and tailored and flexible service delivery. Core ideas of the four domains were identified. The results were consistent with the family support program contents developed in Western countries and suggested culture-specific contents and culturally sensitive service delivery. Clinical implications for developing family support program in South Korea were discussed.

2014-10-01

Informed by Kohn and Schooler's (1969) occupational socialization framework, this study examined linkages between racial/ethnic minority mothers' perceptions of racial/ethnic discrimination in the workplace and adolescents' accounts of racial/ethnic socialization in the home. Data were collected from 100 mother-early adolescent dyads who participated in a longitudinal study of urban adolescents' development in the Northeastern United States, including African American, Latino, and Chinese families. Mothers and adolescents completed surveys separately. We found that when mothers reported more frequent institutional discrimination at work, adolescents reported more frequent preparation for bias messages at home, across racial/ethnic groups. Mothers' experiences of interpersonal prejudice at work were associated with more frequent cultural socialization messages among African American and Latino families. Chinese youth reported fewer cultural socialization messages when mothers perceived more frequent interpersonal prejudice at work. Findings are discussed in the context of minority groups' distinct social histories and economic status in the United States. (PsycINFO Database Record (c) 2014 APA, all rights reserved).

2017-06-01

While effective communication is important in the care of seriously ill patients, little is known about communication challenges faced by healthcare providers serving U.S. patients of South Asian origin, one of the fastest growing demographic groups in the United States. Researchers sought to examine communication challenges faced by healthcare providers serving seriously ill South Asian patients and their families and present strategies recommended by providers for effective communication. Researchers conducted a thematic analysis of qualitative data obtained through focus groups and individual interviews with 57 healthcare providers, including physicians, social workers, nurses, chaplains, and others drawn from different healthcare settings in one Midwestern city. While acknowledging the considerable diversity within the U.S. South Asian community, participants discussed three types of communication challenges they often encounter when serving this population: ensuring effective interpretation, identifying a spokesperson, and challenges posed by different cultural norms. Participants shared strategies to address these challenges such as proactively inquiring about patients' and families' preferences and encouraging early appointment of a spokesperson. While providers should avoid stereotyping patients, an awareness of common challenges and adoption of recommended strategies to address these challenges may enhance the provision of culturally responsive person-centered services for seriously ill South Asian patients and their families receiving care in the United States.

2013-12-01

Clinical failures with cefazolin have been described in high-inoculum infections caused by methicillin-susceptible Staphylococcus aureus (MSSA) producing type A β-lactamase. We investigated the prevalence of the cefazolin inoculum effect (InE) in MSSA from South American hospitals, since cefazolin is used routinely against MSSA due to concerns about the in vivo efficacy of isoxazolyl penicillins. MSSA isolates were recovered from bloodstream (n = 296) and osteomyelitis (n = 68) infections in two different multicentre surveillance studies performed in 2001-02 and 2006-08 in South American hospitals. We determined standard-inoculum (10(5)cfu/mL) and high-inoculum (10(7) cfu/mL) cefazolin MICs. PFGE was performed on all isolates that exhibited a cefazolin InE. Multilocus sequence typing (MLST) and sequencing of part of blaZ were performed on representative isolates. The overall prevalence of the cefazolin InE was 36% (131 isolates). A high proportion (50%) of MSSA isolates recovered from osteomyelitis infections exhibited the InE, whereas it was observed in 33% of MSSA recovered from bloodstream infections. Interestingly, Ecuador had the highest prevalence of the InE (45%). Strikingly, 63% of MSSA isolates recovered from osteomyelitis infections in Colombia exhibited the InE. MLST revealed that MSSA isolates exhibiting the InE belonged to diverse genetic backgrounds, including ST5, ST8, ST30 and ST45, which correlated with the prevalent methicillin-resistant S. aureus clones circulating in South America. Types A (66%) and C (31%) were the most prevalent β-lactamases. Our results show a high prevalence of the cefazolin InE associated with type A β-lactamase in MSSA isolates from Colombia and Ecuador, suggesting that treatment of deep-seated infections with cefazolin in those countries may be compromised.

Two-year outcomes of a randomized, family-based substance use prevention trial for Asian American adolescent girls.

Fang, Lin; Schinke, Steven P

2013-09-01

Asian Americans have been largely ignored in the prevention outcome literature. In this study, we tested a parent-child program with a sample of Asian American adolescent girls and their mothers, and evaluated the program's efficacy on decreasing girls' substance use and modifying risk and protective factors at individual, family, and peer levels. A total of 108 Asian American mother-daughter dyads recruited through online advertisements and from community service agencies were randomly assigned to an intervention arm (n = 56) or to a test-only control arm (n = 52). The intervention consisted of a nine-session substance abuse prevention program, delivered entirely online. Guided by family interaction theory, the prevention program aimed to strengthen the quality of girls' relationships with their mothers while increasing girls' resilience to resist substance use. Intent-to-treat analyses showed that at 2-year follow-up, intervention-arm dyads had significantly higher levels of mother-daughter closeness, mother-daughter communication, maternal monitoring, and family rules against substance use compared with the control-arm dyads. Intervention-arm girls also showed sustained improvement in self-efficacy and refusal skills and had lower intentions to use substances in the future. Most important, intervention-arm girls reported fewer instances of alcohol and marijuana use and prescription drug misuse relative to the control-arm girls. The study suggests that a culturally generic, family-based prevention program was efficacious in enhancing parent-child relationships, improving girls' resiliency, and preventing substance use behaviors among Asian American girls.

African American women report high rates of physical inactivity and related health disparities. In our previous formative research, we conducted a series of qualitative assessments to examine physical activity barriers and intervention preferences among African American women in the Deep South. These data were used to inform a 12-month Home-based, Individually-tailored Physical activity Print (HIPP) intervention, which is currently being evaluated against a wellness contact control condition among 84 post-menopausal African American women residing in the metropolitan area of Birmingham, Alabama. This paper reports the rationale, design and baseline findings of the HIPP trial. The accrued participants had an average age of 57 (SD=4.7), a BMI of 32.1 kg/m(2) (SD=5.16) with more than half (55%) having a college education and an annual household income under $50,000 (53.6%). At baseline, participants reported an average of 41.5 min/week (SD=49.7) of moderate intensity physical activity, and 94.1% were in the contemplation or preparation stages of readiness for physical activity. While social support for exercise from friends and family was low, baseline levels of self-efficacy, cognitive and behavioral processes of change, decisional balance, outcome expectations, and enjoyment appeared promising. Baseline data indicated high rates of obesity and low levels of physical activity, providing strong evidence of need for intervention. Moreover, scores on psychosocial measures suggested that such efforts may be well received. This line of research in technology-based approaches for promoting physical activity in African American women in the Deep South has great potential to address health disparities and impact public health.

Von Pressentin, Klaus B; Mash, Bob J; Esterhuizen, Tonya M

2017-04-28

The supply of appropriate health workers is a key building block in the World Health Organization's model of effective health systems. Primary care teams are stronger if they contain doctors with postgraduate training in family medicine. The contribution of such family physicians to the performance of primary care systems has not been evaluated in the African context. Family physicians with postgraduate training entered the South African district health system (DHS) from 2011. This study aimed to evaluate the impact of family physicians within the DHS of South Africa. The objectives were to evaluate the impact of an increase in family physician supply in each district (number per 10 000 population) on key health indicators. All 52 South African health districts were included as units of analysis. An ecological study evaluated the correlations between the supply of family physicians and routinely collected data on district performance for two time periods: 2010/2011 and 2014/2015. Five years after the introduction of the new generation of family physicians, this study showed no demonstrable correlation between family physician supply and improved health indicators from the macro-perspective of the district. The lack of a measurable impact at the level of the district is most likely because of the very low supply of family physicians in the public sector. Studies which evaluate impact closer to the family physician's circle of control may be better positioned to demonstrate a measurable impact in the short term.

2006-10-01

This study examined the role of parenting, family routines, family conflict, and maternal depression in predicting the social skills and behavior problems of low-income African American preschoolers. A sample of 184 African American mothers of Head Start children completed participant and child measures in a structured interview. Results of regression analyses revealed that mothers who utilized more positive parenting practices and engaged in more family routines had children who displayed higher levels of total prosocial skills. Positive parenting and lower levels of maternal depressive symptoms were predictive of fewer externalizing and internalizing child behavior problems. Lower family conflict was linked with fewer externalizing problems. Implications of the study for future research and intervention are discussed. (c) 2007 APA, all rights reserved

The mediating role of parent-child bonding to prevent adolescent alcohol abuse among Asian American families.

Wang, Meme; Kviz, Frederick J; Miller, Arlene M

2012-10-01

The purpose of this paper is to describe unique culturally-based factors that may increase the vulnerability of Asian American adolescents to engage in alcohol use and abuse and the role of parent-child bonding as a protective factor. In particular, this paper addresses the interactions among acculturation, alcohol use, and parent-child bonding and the challenges Asian American families face in strengthening parent-child bonds. We begin by examining likely causes for alienation that occur as a result of immigration to the United States. We then present the cultural context of Asian American families that can also serve to create distance between parent and child, including the contrasting cultural orientations of individualism and collectivism, Asian traditional values, differences in Eastern and Western parenting styles, and intergenerational cultural dissonance. Next, we present a review of the research that has examined acculturation as a risk factor for alcohol use and abuse among Asian American adolescents, with special attention to the mediating role of parent-child bonding. Finally, we conclude with recommendations for future research on the risk and protective factors for adolescent substance abuse, as well as other risky health behaviors among the growing population of Asian Americans in the United States.

Admixture mapping of lipids was followed-up by family-based association analysis to identify variants for cardiovascular disease in African Americans. The present study conducted admixture mapping analysis for total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and triglycerides. The analysis was performed in 1905 unrelated African American subjects from the National Heart, Lung and Blood Institute's Family Blood Pressure Program (FBPP). Regions showing admixture evidence were followed-up with family-based association analysis in 3556 African American subjects from the FBPP. The admixture mapping and family-based association analyses were adjusted for age, age(2), sex, body mass index, and genome-wide mean ancestry to minimize the confounding caused by population stratification. Regions that were suggestive of local ancestry association evidence were found on chromosomes 7 (low-density lipoprotein cholesterol), 8 (high-density lipoprotein cholesterol), 14 (triglycerides), and 19 (total cholesterol and triglycerides). In the fine-mapping analysis, 52 939 single-nucleotide polymorphisms (SNPs) were tested and 11 SNPs (8 independent SNPs) showed nominal significant association with high-density lipoprotein cholesterol (2 SNPs), low-density lipoprotein cholesterol (4 SNPs), and triglycerides (5 SNPs). The family data were used in the fine-mapping to identify SNPs that showed novel associations with lipids and regions, including genes with known associations for cardiovascular disease. This study identified regions on chromosomes 7, 8, 14, and 19 and 11 SNPs from the fine-mapping analysis that were associated with high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and triglycerides for further studies of cardiovascular disease in African Americans. © 2014 American Heart Association, Inc.

Edwarsiella tarda is a zoonotic bacterium that can be isolated from humans, animals and the environment. Although E. tarda is primarily considered a fish pathogen, it is the only species of its genus considered to be pathogenic for humans as well. A survey of zoonotic intestinal bacteria in fresh feces from South American sea lions (SASL) Otaria flavescens, reported E. tarda as the most frequently isolated species. In this study, we used HEp-2 cells to establish in vitro the adherence and inv...

Redefining American Families: The Disparate Effects of IIRIRA's Automatic Bars to Reentry and Sponsorship Requirements on Mixed-Citizenship Couples

Directory of Open Access Journals (Sweden)

Jane Lilly Lopez

2017-04-01

Full Text Available With passage of the Illegal Immigration Reform and Immigrant Responsibility Act of 1996 (IIRIRA, the goal of discouraging illegal immigration and the legal immigration of the poor triumphed over the longstanding goal of family unity in US immigration policy. This shift resulted in policy changes that prevent some mixed-citizenship families from accessing family reunification benefits for the immigrant relatives of US citizens. Two specific elements of IIRIRA — (1 the three- and 10-year bars to reentry, and (2 the minimum income thresholds for citizen sponsors of immigrants — have created a hierarchy of mixed-citizenship families, enabling some to access all the citizenship benefits of family preservation and reunification, while excluding other, similar families from those same benefits. This article details these two key policy changes imposed by IIRIRA and describes their impact on mixed-citizenship couples seeking family reunification benefits in the United States. Mixed-citizenship couples seeking family reunification benefits do not bear the negative impacts of these two policies evenly. Rather, these policies disproportionately limit specific subgroups of immigrants and citizens from accessing family reunification. Low-income, non-White (particularly Latino, and less-educated American families bear the overwhelming brunt of IIRIRA’s narrowing of family reunification benefits. As a result, these policy changes have altered the composition of American society and modified broader notions of American national identity and who truly “belongs.” Most of the disparate impact between mixed-citizenship couples created by the IIRIRA would be corrected by enacting minor policy changes to (1 allow the undocumented spouses of US citizens to adjust their legal status from within the United States, and (2 include the noncitizen spouse’s income earning potential toward satisfying minimum income requirements.

The Tetramerium lineage (Acanthaceae) presents a striking ecological structuring in South America, with groups concentrated in moist forests or in seasonally dry forests. In this study, we investigate the circumscription and relationships of the South American genera as a basis for better understanding historic interactions between dry and moist biomes in the Neotropics. We dated the ancestral distribution of the Tetramerium lineage based on one nuclear and four plastid DNA regions. Maximum parsimony, maximum likelihood, and Bayesian inference analyses were performed for this study using 104 terminals. Phylogenetic divergences were dated using a relaxed molecular clock approach and ancestral distributions obtained from dispersal-vicariance analyses. The genera Pachystachys, Schaueria, and Thyrsacanthus are nonmonophyletic. A dry forest lineage dispersed from North America to South America and reached the southwestern part of the continent between the end of the Miocene and beginning of the Pleistocene. This period coincides with the segregation between Amazonian and Atlantic moist forests that established the geographic structure currently found in the group. The South American genera Pachystachys, Schaueria, and Thyrsacanthus need to be recircumscribed. The congruence among biogeographical events found for the Tetramerium lineage suggests that the dry forest centers currently dispersed throughout South America are relatively old remnants, probably isolated since the Neogene, much earlier than the Last Glacial Maximum postulated by the Pleistocene Arc hypothesis. In addition to exploring the Pleistocene Arc hypothesis, this research also informs evolution in a lineage with numerous geographically restricted and threatened species. © 2015 Botanical Society of America, Inc.

Self-construal, mental distress, and family relations: a mediated moderation analysis with Asian American adolescents.

Science.gov (United States)

Liu, Freda F; Goto, Sharon G

2007-04-01

The interactive effects between interdependent and independent self-construal on family cohesion and mental distress were examined. Survey responses from 153 Asian American high school students supported the hypothesized moderation of interdependence by independence on family cohesion, which was found to further mediate the relationship between self-construal and mental distress. Specifically, interdependence was positively associated with family cohesion when independence was high and negatively associated with family cohesion when independence was low. Accounting for the mediator effects of family cohesion, mental distress was positively associated with interdependence and more so for those low on independence than those high on independence. The benefits of biculturalism and research implications for the bidimensional conceptualization of self-construal for ethnic minority populations are discussed. (c) 2007 APA, all rights reserved.

Lee, Bora; Padilla, Jenny; McHale, Susan M

2016-11-01

A strong work ethic generally has positive implications for achievements in work and school settings, but we know little about how it develops. This study aimed to describe the intra-familial transmission of work ethic and the associations between work ethic and adjustment in African American youth. Mothers, fathers, and two adolescent siblings (M age  = 14.1 years) in 158 families were interviewed on two occasions. Path models revealed that fathers' work ethic was positively linked with older siblings' work ethic, which in turn was linked with more positive youth adjustment in the domains of school functioning and externalizing and internalizing problems. Moreover, the results indicated that the work ethics of older siblings, but not parents, was linked to those of younger siblings. The discussion focuses on the importance of African American fathers and siblings in youth adjustment and how work ethic may promote positive development.

Exposure to perfluorinated alkyl acids (PFAAs) has been linked to many harmful health effects including reproductive disorders, developmental delays, and altered liver and kidney function. Most human exposure to environmental contaminants, including PFAAs, occurs through consumption of contaminated food or drinking water. This study uses PFAA data from meat samples collected from recreationally harvested American alligators (Alligator mississippiensis) in South Carolina to assess potential dietary exposure of hunters and their families to PFAAs. Consumption patterns were investigated using intercept surveys of 23 hunters at a wild game meat processor. An exposure scenario using the average consumption frequency, portion size, and median perfluorooctane sulfonic acid (PFOS) concentration in alligator meat from all hunt units found the daily dietary exposure to be 2.11ng/kg body weight per day for an adult human. Dietary PFOS exposure scenarios based on location of harvest suggested the highest daily exposure occurs with alligator meat from the Middle Coastal hunt unit in South Carolina. Although no samples were found to exceed the recommended threshold for no consumption of PFOS found in Minnesota state guidelines, exposure to a mixture of PFAAs found in alligator meat and site-specific exposures based on harvest location should be considered in determining an appropriate guideline for vulnerable populations potentially exposed to PFAAs through consumption of wild alligator meat.

Theileria equi is a tick-borne piroplasm considered endemic in equines in Brazil. The cohabitation of domestic and wild animals in areas of extensive cattle breeding favors the close contact between different species and the sharing of vectors and, consequently, pathogens. We report the natural infection of a young South American tapir ( Tapirus terrestris ) by T. equi in Mato Grosso do Sul, Brazil. Although it was not possible to associate the clinical and hematologic status of the animal with the infection by the protozoan parasite, our report represents an alert on the sharing of pathogens between domestic and wild animals.

The United States National Aeronautics and Space Administration (NASA) and the Brazilian Commission for Space Activities (COBAE) are undertaking a joint experiment involving NASA's DC-8 research aircraft and the Airborne Synthetic Aperture Radar (AIRSAR) system during late May and June 1993. The research areas motivating these activities are: (1) fundamental research in the role of soils, vegetation, and hydrology in the global carbon cycle; and (2) in cooperation with South American scientists, airborne remote sensing research for the upcoming NASA Spaceborne Imaging Radar (SIR)-C/X-SAR flights on the Space Shuttle. A flight schedule and plans for the deployment that were developed are included. Maps of the site locations and schematic indications of flight routes and dates, plots showing swath locations derived from the flight requests and generated by flight planning software, and, most importantly, a calendar showing which sites will be imaged each day are included.

Parental Endorsement of Spanking and Children’s Internalizing and Externalizing Problems in African American and Hispanic Families

Coley, Rebekah Levine; Kull, Melissa A.; Carrano, Jennifer

2014-01-01

This study assessed prospective, bidirectional associations between maternal endorsement of spanking and children’s internalizing and externalizing behavior problems in low-income urban African American and Hispanic (N = 592) families drawn from the Three City Study. Children in sample families were followed from early childhood through middle childhood with three sets of interviews and assessments at ages 3, 4, and 9 years. Cross-lagged path analyses tested longitudinal bidirectional associations between parental endorsement of spanking and children’s internalizing and externalizing problems, with multi-group comparisons employed to test group differences between race/ethnic groups. African American and Hispanic mothers showed similar endorsements of spanking. Results suggest that associations between spanking endorsement and child functioning were due primarily to parenting effects, with spanking predicting changes in children’s behaviors, rather than child evocative effects, with limited evidence of child behaviors predicting changes in parental spanking. Maternal spanking endorsement predicted short-term decreases in children’s internalizing problems in early childhood, but over the longer term spanking was associated with increased internalizing and externalizing problems for both African American and Hispanic children in middle childhood among economically disadvantaged families.

AFRICAN-STYLE MEDIATION AND WESTERN-STYLE DIVORCE AND FAMILY MEDIATION: REFLECTIONS FOR THE SOUTH AFRICAN CONTEXT

Directory of Open Access Journals (Sweden)

AE Boniface

2012-12-01

Full Text Available Both Western-styled mediation and African-styled mediation are practised in South Africa. Each of these models is applied in specific social contexts. In this article a brief explanation of what is meant by the term divorce and family mediation is provided. Thereafter the principles and processes of both Western-styled divorce and family mediation and African-styled group mediation are explored. Attention is given to the roles of mediators in both of these models as well as the ubuntu-styled values found in African group mediation. In Africa, there is a tradition of family neighbourhood negotiation facilitated by elders and an attitude of togetherness in the spirit of humanhood. Both of these show a commitment to the community concerned and a comprehensive view of life. In Africa conflicts are viewed as non-isolated events and are viewed in their social contexts. Not only are consequences for the disputing parties taken into account but also consequences for others in their families. These methods can be found in present-day methods, which are either used independently of imported Western structures or used alternatively to such structures. In this article the concept of mediation circles, as currently found in Western-styled mediation are also covered. Additionally, the provisions of the Children’s Act 38 of 2005 referring to mediation as well as the provisions of the Child Justice Act 75 of 2008 and family group conferencing in the realm of restorative justice in South Africa are critiqued. It is suggested that divorce and family mediation can learn from the principles of restorative justice applied during family group conferencing as well as from African-styled group mediation.

Coalescent Simulation and Paleodistribution Modeling for Tabebuia rosealba Do Not Support South American Dry Forest Refugia Hypothesis.

Gitelman syndrome (GS) is an autosomal recessive renal tubular disorder characterised by renal salt wasting with hypokalaemia, metabolic alkalosis, hypomagnesaemia and hypocalciuria. It is caused by mutations in SLC12A3 encoding the sodium-chloride cotransporter on the apical membrane of the distal convoluted tubule. We report a South African family with five affected individuals presenting with hypokalaemia and unusual food cravings. The affected individuals and two unaffected first degree relatives were enrolled into the study. Phenotypes were evaluated through history, physical examination and biochemical analysis of blood and urine. Mutation screening was performed by sequencing of SLC12A3, and determining the allele frequencies of the sequence variants found in this family in 117 ethnically matched controls. The index patient, her sister, father and two aunts had a history of severe salt cravings, fatigue and tetanic episodes, leading to consumption of large quantities of salt and vinegar. All affected individuals demonstrated hypokalaemia with renal potassium wasting. Genetic analysis revealed that the pseudo-dominant pattern of inheritance was due to compound heterozygosity with two novel mutations: a S546G substitution in exon 13, and insertion of AGCCCC at c.1930 in exon 16. These variants were present in the five affected individuals, but only one variant each in the unaffected family members. Neither variant was found in any of the controls. The diagnosis of GS was established in five members of a South African family through clinical assessment, biochemical analysis and mutation screening of the SLC12A3 gene, which identified two novel putative pathogenic mutations.

Cornelius, Judith B; Whitaker-Brown, Charlene D

2017-06-01

Guided by the relational cultural theory, we conducted a qualitative study to examine the relationship experiences of African American transgender women living in North Carolina. A convenience sample of 15 transgender women participated in the study. Semi-structured interviews, guided by an investigator-developed interview guide, were used to explore the personal experiences of transgender women on individual, family, and organizational levels. The findings provide a scheme for understanding the process through which transgender women's relationships hinder or enhance their ability to connect with individuals, family, and organizations. Nurses can use these findings to better understand the connectedness that occurs or does not occur in transgender women's relationships and provide culturally competent care to empower them to become resilient.

Folk medicinal plants are potential sources of useful therapeutic compounds including some with antiviral activities. Extracts prepared from 10 South American medicinal plants (Baccharis trinervis, Baccharis teindalensis, Eupatorium articulatum, Eupatorium glutinosum, Tagetes pusilla, Neurolaena lobata, Conyza floribunda, Phytolacca bogotensis, Phytolacca rivinoides and Heisteria acuminata) were screened for in vitro antiviral activity against herpes simplex type I (HSV-1), vesicular stomatitis virus (VSV) and poliovirus type 1. The most potent inhibition was observed with an aqueous extract of B. trinervis, which inhibited HSV-1 replication by 100% at 50-200 micrograms/mL, without showing cytotoxic effects. Good activities were also found with the ethanol extract of H. acuminata and the aqueous extract of E. articulatum, which exhibited antiviral effects against both DNA and RNA viruses (HSV-1 and VSV, respectively) at 125-250 micrograms/mL. The aqueous extracts of T. pusilla (100-250 micrograms/mL), B. teindalensis (50-125 micrograms/mL) and E. glutinosum (50-125 micrograms/mL) also inhibited the replication of VSV, but none of the extracts tested had any effect on poliovirus replication.

By 2000, an estimated 80% of South America’s population lived in urban areas (Veblen et al., The Physical Geography of South America, Oxford University Press, 2007). A significant fraction of those urban dwellers resides in the capital cities which are major economic centers and act as magnets for rural poor and refugees. This population concentration includes many residents living in extreme poverty in substandard and informal housing, often on the margins of these capital cities and sometimes on steep slopes, greatly compounding the vulnerability to natural hazards. We are analyzing the humanitarian and economic risk for six of the seismically most-at-risk South American capitals along the northern and western plate boundaries of South America: Caracas, Venezuela; Bogotá, Colombia; Quito, Ecuador; Lima, Perú; La Paz, Bolivia; and Santiago, Chile. Impacts are provided in the form of expected losses for a specific “likely” scenario earthquake and in a probabilistic format using exceedance probability curves (probability of exceeding a given loss in different return periods). Impacts to be quantified include: total economic losses, potential fatalities, potential serious injuries, and the number of displaced households. Probabilistic seismic hazard was developed in collaboration with numerous South American experts and includes subduction interface, intraslab, background crustal and, where available, active fault sources. A significant challenge for this study is to accurately account for the exposure and vulnerability of populations living in the informal, shanty areas. Combining analysis of aerial imagery and on-the-ground reconnaissance, we define between 20-30 “inventory districts” of relatively uniform construction styles within each capital. Statistical distributions of the different construction types and their characteristics (height, occupancy, year built, average value) are estimated for each district. In addition, working with local graduate

Objective Little is known about how older African American women define family violence (FV) and what FV survivors might expect from their healthcare providers. The purpose of this study was to understand how these women define FV, where they seek help for FV, and what barriers they face in these efforts. Methods We conducted 6 focus groups with 30 African American women over the age of 50, including some FV survivors, at a large, inner-city public hospital. Results Participants defined FV broadly, citing examples of abuse (physical, sexual, emotional and financial) and neglect. Spiritual sources were cited over physicians as being available to help FV survivors. Barriers to receiving assistance included negative encounters with physicians, lack of trust in the system and dearth of age-appropriate resources. Conclusions For older African American women, FV takes many forms of which many may not be obvious during the clinical encounter. Like younger FV survivors, they expect physicians to serve as a resource for FV. Practice implications Physicians caring for older African American women need to remember to ask them about FV, and when making referrals for abuse and neglect, consider offering referrals to pastoral care if appropriate.

Cigarette smoke is a strong risk factor for obesity and cardiovascular disease. The effect of genetic variants involved in nicotine metabolism on obesity or body composition has not been well studied. Though many genetic variants have previously been associated with adiposity or body fat distribution, a single variant usually confers a minimal individual risk. The goal of this study is to evaluate the joint association of multiple variants involved in cigarette smoke or nicotine dependence with obesity-related phenotypes in American Indians. To achieve this goal, we genotyped 61 tagSNPs in seven genes encoding nicotine acetylcholine receptors (nAChRs) in 3,665 American Indians participating in the Strong Heart Family Study. Single SNP association with obesity-related traits was tested using family-based association, adjusting for traditional risk factors including smoking. Joint association of all SNPs in the seven nAChRs genes were examined by gene-family analysis based on weighted truncated product method (TPM). Multiple testing was controlled by false discovery rate (FDR). Results demonstrate that multiple SNPs showed weak individual association with one or more measures of obesity, but none survived correction for multiple testing. However, gene-family analysis revealed significant associations with waist circumference (p = 0.0001) and waist-to-hip ratio (p = 0.0001), but not body mass index (p = 0.20) and percent body fat (p = 0.29), indicating that genetic variants are jointly associated with abdominal, but not general, obesity among American Indians. The observed combined genetic effect is independent of cigarette smoking per se. In conclusion, multiple variants in the nAChR gene family are jointly associated with abdominal obesity in American Indians, independent of general obesity and cigarette smoking per se.

2015-06-01

Exposure to suicide in social relationships may be associated with suicidal ideation among survivors. In South Korea, which is known for having the highest suicide rate among OECD countries, exposure to suicide in social relationships can have serious consequences as social relationships are greatly emphasized in the society. The purpose of this study was to examine the association between survivors' suicidal ideation and their exposure to suicide in close relationships. Data collected through a telephone survey of a total of 1,000 men and women selected from across the nation using a stratified sampling method were analyzed. The results show that individuals who lost a family member, friend, or acquaintance in their lifetime are 4.5 times, 3.7 times, 2.2 times, respectively, more likely to have suicidal ideation in the past year compared to those without such experience.

Cosmic ray scientific community deserves special attention to the Chacaltaya site for its over 5 km altitude. In this site, a neutron monitor of the IGY type operated from 1960 to 1969, and the one of the NM-64 type since 1966 (16.31{sup 0}S, 291.85{sup 0}E, height: about 5200 m a.s.l.). It was discussed the relevance of such kind of detector when it is integrated with the other South-American neutron monitors: a) LARC (62.20{sup 0}S, 301.04{sup 0}E, height: 40 m a.s.l., King George Island, Antarctica; operating since 1991); b) Los Cerrillos (33.45{sup 0}S, 289.40{sup 0}E, height: 570 m a. s. l., Santiago, Chile; to be installed in the near future); c) Huancayo (12.03{sup 0}S, 284.67{sup 0}E, height: 3400 m a.s.l., Huancayo, Peru; hoping to recover its acquired data).

Dinosaur speed demon: the caudal musculature of Carnotaurus sastrei and implications for the evolution of South American abelisaurids.

Directory of Open Access Journals (Sweden)

W Scott Persons

Full Text Available In the South American abelisaurids Carnotaurus sastrei, Aucasaurus garridoi, and, to a lesser extent Skorpiovenator bustingorryi, the anterior caudal ribs project at a high dorsolateral inclination and have interlocking lateral tips. This unique morphology facilitated the expansion of the caudal hypaxial musculature at the expense of the epaxial musculature. Distinct ridges on the ventrolateral surfaces of the caudal ribs of Aucasaurus garridoi are interpreted as attachment scars from the intra caudofemoralis/ilio-ischiocaudalis septa, and confirm that the M. caudofemoralis of advanced South American abelisaurids originated from a portion of the caudal ribs. Digital muscle models indicate that, relative to its overall body size, Carnotaurus sastrei had a substantially larger M. caudofemoralis than any other theropod yet studied. In most non-avian theropods, as in many extant sauropsids, the M. caudofemoralis served as the primary femoral retractor muscle during the locomotive power stroke. This large investment in the M. caudofemoralis suggests that Carnotaurus sastrei had the potential for great cursorial abilities, particularly short-burst sprinting. However, the tightly interlocking morphology of the anterior caudal vertebrae implies a reduced ability to make tight turns. Examination of these vertebral traits in evolutionary context reveals a progressive sequence of increasing caudofemoral mass and tail rigidity among the Abelisauridae of South America.

Weerasinghe, Swarna; Maddalena, Victor

2016-01-01

In the present study, we explored family caregivers' experiences in providing end-of-life care for terminally ill South Asian immigrants. We employed qualitative methods and. in-depth interviews were conducted with seven family caregivers living in Nova Scotia, Canada. Interview data were validated, coded and organized for themes. Three major themes identified in the data illustrated (a) how South Asian caregivers experienced clashes between biomedical and ethno-cultural realms of care that led to cultural insensitivity, (b) how family members acted as mediators, and (c) how communication issues that challenged cultural sensitivity were handled. Findings provide directions for culturally sensitive end-of-life care planning.

2010-06-01

Full Text Available As the shift towards inclusive education intensifies, the need for school to work collaboratively with families becomes necessaryfor the sake of maximizing students’ academic success. However, in certain communities such effort is often undermined byvarious factors which interact directly and/or indirectly with both institutions – school and family. Schools located in informalsettlements of South Africa are not unique to this situation. This paper presents the perspectives of parents, educators andschool management teams about barriers which inhibit collaboration between the school and families. Interviews conducted ingroups and with individual participants were followed as data collection strategies. Findings revealed factors falling under threecategories, namely: community, schools and family factors. These factors interact with each other in a dynamic way to createchallenges to undermine school-family collaboration. The findings of this study could guide school efforts for promotingmeaningful and long-lasting relationships with families.

This study examined the quality of family relationships and its associations with the severity of unmet needs of individuals admitted to a tertiary psychiatric hospital in South Africa. The quality of family relations and perceived unmet needs were assessed using the Lehman Quality of Life Interview and Camberwell Assessment of Needs, respectively. The results show that higher total unmet needs were associated with lower quality of family relations. The main areas of serious unmet needs included accessing government benefits and information, and establishing social relations. The results have implications for hospital-based social workers beyond managing psychiatric symptoms in South Africa.

Background Admixture mapping of lipids was followed-up by family-based association analysis to identify variants for cardiovascular disease in African-Americans. Methods and Results The present study conducted admixture mapping analysis for total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and triglycerides. The analysis was performed in 1,905 unrelated African-American subjects from the National Heart, Lung and Blood Institute’s Family Blood Pressure Program. Regions showing admixture evidence were followed-up with family-based association analysis in 3,556 African-American subjects from the FBPP. The admixture mapping and family-based association analyses were adjusted for age, age2, sex, body-mass-index, and genome-wide mean ancestry to minimize the confounding due to population stratification. Regions that were suggestive of local ancestry association evidence were found on chromosomes 7 (LDL-C), 8 (HDL-C), 14 (triglycerides) and 19 (total cholesterol and triglycerides). In the fine-mapping analysis, 52,939 SNPs were tested and 11 SNPs (8 independent SNPs) showed nominal significant association with HDL-C (2 SNPs), LDL-C (4 SNPs) and triglycerides (5 SNPs). The family data was used in the fine-mapping to identify SNPs that showed novel associations with lipids and regions including genes with known associations for cardiovascular disease. Conclusions This study identified regions on chromosomes 7, 8, 14 and 19 and 11 SNPs from the fine-mapping analysis that were associated with HDL-C, LDL-C and triglycerides for further studies of cardiovascular disease in African-Americans.

2007-08-01

Full Text Available Abstract Background Hepatitis C virus (HCV has been the subject of intense research and clinical investigation as its major role in human disease has emerged. Previous and recent studies have suggested a diversification of type 1 HCV in the South American region. The degree of genetic variation among HCV strains circulating in Bolivia and Colombia is currently unknown. In order to get insight into these matters, we performed a phylogenetic analysis of HCV 5' non-coding region (5'NCR sequences from strains isolated in Bolivia, Colombia and Uruguay, as well as available comparable sequences of HCV strains isolated in South America. Methods Phylogenetic tree analysis was performed using the neighbor-joining method under a matrix of genetic distances established under the Kimura-two parameter model. Signature pattern analysis, which identifies particular sites in nucleic acid alignments of variable sequences that are distinctly representative relative to a background set, was performed using the method of Korber & Myers, as implemented in the VESPA program. Prediction of RNA secondary structures was done by the method of Zuker & Turner, as implemented in the mfold program. Results Phylogenetic tree analysis of HCV strains isolated in the South American region revealed the presence of a distinct genetic lineage inside genotype 1. Signature pattern analysis revealed that the presence of this lineage is consistent with the presence of a sequence signature in the 5'NCR of HCV strains isolated in South America. Comparisons of these results with the ones found for Europe or North America revealed that this sequence signature is characteristic of the South American region. Conclusion Phylogentic analysis revealed the presence of a sequence signature in the 5'NCR of type 1 HCV strains isolated in South America. This signature is frequent enough in type 1 HCV populations circulating South America to be detected in a phylogenetic tree analysis as a distinct

Full Text Available The general aim of the research was to theoretically and empirically study and evaluate job and family stressors amongst firefighters in the South African context. This also included an empirical evaluation of the stress symptoms of firefighters. The research was quantitative, consisting of a survey design. Three measuring instruments were used, namely the Experience of Work and Life Circumstances questionnaire, the Stress questionnaire as well as a biographical questionnaire. Task characteristics, organisational functioning, physical working conditions and job equipment, career and social matters, remuneration, fringe benefits and personnel policy were identified as causes of job stress originating within the work situation. Marital dysfunction and divorce, limited time with the family, problems with children, alcohol and drug abuse, lack of exercise, suicide, anger aimed at family members, physical and emotional exhaustion, lonely marital partners, unavailability to help the family when needed and depression were identified as causes of family stress arising outside the work situation.

Are there common familial influences for major depressive disorder and an overeating-binge eating dimension in both European American and African American female twins?

Although prior studies have demonstrated that depression is associated with an overeating-binge eating dimension (OE-BE) phenotypically, little research has investigated whether familial factors contribute to the co-occurrence of these phenotypes, especially in community samples with multiple racial/ethnic groups. We examined the extent to which familial (i.e., genetic and shared environmental) influences overlapped between Major Depressive Disorder (MDD) and OE-BE in a population-based sample and whether these influences were similar across racial/ethnic groups. Participants included 3,226 European American (EA) and 550 African American (AA) young adult women from the Missouri Adolescent Female Twin Study. An adaptation of the Semi-Structured Assessment for the Genetics of Alcoholism (SSAGA) was administered to assess lifetime DSM-IV MDD and OE-BE. Quantitative genetic modeling was used to estimate familial influences between both phenotypes; all models controlled for age. The best-fitting model, which combined racial/ethnic groups, found that additive genetic influences accounted for 44% (95% CI: 34%, 53%) of the MDD variance and 40% (25%, 54%) for OE-BE, with the remaining variances due to non-shared environmental influences. Genetic overlap was substantial (rg  = .61 [.39, .85]); non-shared environmental influences on MDD and OE-BE overlapped weakly (re  = .26 [.09, .42]). Results suggest that common familial influences underlie MDD and OE-BE, and the magnitude of familial influences contributing to the comorbidity between MDD and OE-BE is similar between EA and AA women. If racial/ethnic differences truly exist, then larger sample sizes may be needed to fully elucidate familial risk for comorbid MDD and OE-BE across these groups. © 2014 Wiley Periodicals, Inc.

The purpose of this paper is to describe the rationale, design, methods and baseline results of the Family Spirit trial. The goal of the trial is to evaluate the impact of the paraprofessional-delivered "Family Spirit" home-visiting intervention to reduce health and behavioral risks for American Indian teen mothers and their children. A community based participatory research (CBPR) process shaped the design of the current randomized controlled trial of the Family Spirit intervention. Between 2006 and 2008, 322 pregnant teens were randomized to receive the Family Spirit intervention plus Optimized Standard Care, or Optimized Standard Care alone. The Family Spirit intervention is a 43-session home-visiting curriculum administered by American Indian paraprofessionals to teen mothers from 28 weeks gestation until the baby's third birthday. A mixed methods assessment administered at nine intervals measures intervention impact on parental competence, mother's and children's social, emotional and behavioral risks for drug use, and maladaptive functioning. Participants are young (mean age = 18.1 years), predominantly primiparous, unmarried, and challenged by poverty, residential instability and low educational attainment. Lifetime and pregnancy drug use were ~2-4 times higher and ~5-6 times higher, respectively, than US All Races. Baseline characteristics were evenly distributed between groups, except for higher lifetime cigarette use and depressive symptoms among intervention mothers. If study aims are achieved, the public health field will have new evidence supporting multi-generational prevention of behavioral health disparities affecting young American Indian families and the utility of indigenous paraprofessional interventionists in under-resourced communities.

Full Text Available In the XXI century, much of humanity does not have access to comprehensive health care, or even basic equitable health care. If studies show that countries with organized health systems based on a qualified and inclusive model of Primary Health Care (PHC and family physicians as permanent staff are achieving unquestionable results, why a large part of the countries with lower socio-economic development have not committed strongly to implement an efficient reform of their health systems based on PHC and family medicine (FM? These issues are at the core of the Latin American Confederation of Family Medicine’s concerns, an international non-profit organization composed of national associations of countries of FM from Latin America, Spain and Portugal. Its primary mission is to drive the implementation of a proper PHC system in all countries of the region and to ensure that family medicine, as a specialty, is considered critical to health systems, thereby transforming it into a public policy.

Phylogeny of Amazona barbadensis and the Yellow-headed Amazon complex (Aves: Psittacidae): a new look at South American parrot evolution.

Science.gov (United States)

Urantówka, Adam Dawid; Mackiewicz, Paweł; Strzała, Tomasz

2014-01-01

The Yellow-shouldered Amazon (Amazona barbadensis) is the sole parrot of the genus Amazona that inhabits only dry forests. Its population has been dropping; therefore it has been the topic of many studies and conservation efforts. However, the phylogenetic relationship of this species to potential relatives classified within the Yellow-Headed Amazon (YHA) complex are still not clear. Therefore, we used more extensive data sets, including the newly sequenced mitochondrial genome of A. barbadensis, to conduct phylogenetic analyses. Various combinations of genes and many phylogenetic approaches showed that A. barbadensis clustered significantly with A. ochrocephala ochrocephala from Colombia and Venezuela, which created the Northern South American (NSA) lineage, clearly separated from two other lineages within the YHA complex, the Central (CA) and South American (SA). Tree topology tests and exclusion of rapidly evolving sites provided support for a NSA+SA grouping. We propose an evolutionary scenario for the YHA complex and its colonization of the American mainland. The NSA lineage likely represents the most ancestral lineage, which derived from Lesser Antillean Amazons and colonized the northern coast of Venezuela about a million years ago. Then, Central America was colonized through the Isthmus of Panama, which led to the emergence of the CA lineage. The southward expansion to South America and the origin of the SA lineage happened almost simultaneously. However, more intensive or prolonged gene flow or migrations have led to much weaker geographic differentiation of genetic markers in the SA than in the CA lineage.

The purpose of this study was to explore the association between the dynamics of family structure and sexual behaviors of African-American adolescents using the ecodevelopmental theory. This study stratified data from 1,617 African-American adolescents of the Add Health Wave I respondents with an identified family composition. It examined the associations between family structure, parenting function, and adolescents' sexual decision-making: age of first sexual intercourse, sexual initiation before age 16, and using a condom during the first and last sexual intercourse. Emotional connection between parents and children (feeling more love from the father: β=0.17, P =0.0312; feeling more love from the mother: β=0.3314, P =0.0420) and mothers' less permissive attitude toward adolescents' sexual experience in their teens (β=0.33, P =0.0466) are positively associated with late age of sexual initiation of adolescents living in two-parent households. School-level factors (β=0.07, P =0.0008) and the adolescents' characteristics (being older: 0.42, P =0.0002; heterosexuality: β=2.28, P =0.0091) are the factors most positively related to the age of sexual initiation for those living with a single parent. Immediate social determinants, other than family factors (such as land use of immediate area [rural]: β=9.84, P <0.0001; the condition of living unit: β=1.55, P =0.0011; and safety of neighborhood: β=4.46, P =0.004), are related to late age of sexual initiation among those living with other relatives/alone. A higher tendency of condom use consistency was present in adolescents living with two parents compared to those living in other family structures. Less parent/child connection and parent/family influence were found in African-American adolescents living with other relatives or alone, suggesting that living with two residential parents plays an essential role in their late sexual initiation and could account for an important element to combat high HIV incidence of

Although there are many studies regarding phenolic compounds in wines, there is a lack of information about antioxidants and phenolic content in South American wines. In this study, 35 South American red wines from four different countries, vintages 2004–2013, purchased at retail stores in La Paz, Bolivia, were studied. Resveratrol content, total antioxidant capacity (TAC by the 2,2′-azino-bis(3-ethylbenzotiazoline-6-sulfonic acid (ABTS and ferric-reducing antioxidant power (FRAP methods, total phenolic content (TPH, total flavonoids (TF, and main saccharides were assessed using the well-established spectrophotometric and high-performance liquid chromatography methods. The results ranged from 4 to 24 mmol/L for TAC determined by ABTS method and 14 to 43 mmol/L for TAC determined by FRAP method, 1600 to 3500 mg gallic acid equivalents/L for TPH, and 2 to 6 mmol catechin equivalents /L for TF. The resveratrol content ranged from 0.1 to 8 mg/L. Saccharides, glucose, and fructose content ranged from 0.4 to 10 g/L, 1.4 to 8.6 g/L, and 0.2 to 12 g/L, respectively. There was a high correlation among the different methods. The results showed that some wines growing at high altitude (>1500 meters above the sea level have higher amounts of TAC and phenolic content, including resveratrol, while non-varietal wines showed the lowest values. It was also observed that the saccharose
