    Recovery for diverse populations with mental health problems includes communities of color, those with limited English proficiency and individuals who are lesbian, gay, bisexual or transgender (LGBT). The process of healing and recovery must take into consideration the critical role of culture and language and look at the individual within the context of an environment that is influenced by racism, sexism, colonization, homophobia, and poverty as well as the stigma and shame associated with having a mental illness. Recovery must assess the impact of isolation brought about by cultural and language barriers and work towards reducing the negative influence it has on the emotional and physical well-being of the person. It is imperative that recovery occur at multiple levels and involves the person in recovery, the service provider, the larger community and the system that establishes policies that often work against those who do not fit the mold of what mainstream society considers being "the norm." Recovery must respect the cultural and language backgrounds of the individual.

  2. Breast cancer screening: cultural beliefs and diverse populations.

    This article addresses the role of culture in breast cancer screening behavior among African American, American Indian/Alaskan Native, Asian American/Pacific Islander, and Hispanic/ Latina women. It reviews cultural beliefs, attitudes, and knowledge and their relative influence on women's decisions regarding health tests. The article explores how to build on these cultural values, simultaneously mediating their barrier effects. Building on cultural explanatory models of health behavior, suggestions for incorporating culture into early detection strategies for ethnically and racially diverse, underserved women are provided. In addition, the article offers four practice principles that can be used with all of the groups: inclusion and use of indigenous support; cross-application of approaches for diverse populations; honor and incorporation of culture; and attention to language, literacy, and cultural information.

  3. A population memetics approach to cultural evolution in chaffinch song: meme diversity within populations.

    1993-04-01

    We investigated cultural evolution in populations of common chaffinches (Fringilla coelebs) in the Atlantic islands (Azores, Madeira, Canaries) and neighboring continental regions (Morocco, Iberia) by employing a population memetics approach. To quantify variability within populations, we used the concept of a song meme, defined as a single syllable or a series of linked syllables capable of being transmitted. The frequency distribution of memes within populations generally fit a neutral model in which there is an equilibrium between mutation, migration, and drift, which suggests that memes are functionally equivalent. The diversity of memes of single syllables is significantly greater in the Azores compared to all other regions, consistent with higher population densities of chaffinches there. On the other hand, memes of two to five syllables have greater diversity in Atlantic island and Moroccan populations compared to their Iberian counterparts. This higher diversity emanates from a looser syntax and increased recombination in songs, presumably because of relaxed selection for distinctive songs in these peripheral and depauperate avifaunas. We urge comparative population memetic studies of other species of songbirds and predict that they will lead to a formulation of a general theory for the cultural evolution of bird song analogous to population genetics theory for biological traits.

  4. A culturally diverse staff population: challenges and opportunities for nurses.

    The United States is seeing an increase in ethnic and cultural diversity that is reflected (albeit to a smaller extent) in the nursing workforce. There are also more nurses who are foreign-born and educated. These nurses bring elements of their ethnic culture to the healthcare setting, including that of the "healthcare provider" culture of their home country. Often these values conflict with, or at least differ from, many American values seen in the workplace, such as autonomy of patients, an individualistic approach to relationships, peer relationships rather than hierarchical ones, democracy as an ideal norm, optimal health is ideal, and an emphasis on time/schedules and use of technology. A major cultural difference in the work setting has to do with the meaning of "work" itself, which can vary among cultural groups; in addition, some cultures are viewed as more "collective" in nature than the American ones, which are considered "individualistic." In particular, foreign-born and educated nurses from different healthcare systems bring with them values of the political system in which they work, the concept of a socialized system of medicine, language and accent differences, different concepts of nursing duties, and varying psychosocial skills.

    Despite compelling arguments for the dissemination of evidence-based treatments (EBTs), questions regarding their relevance to ethnically diverse populations remain. This review summarizes what is known about psychotherapy effects with ethnic minorities, with a particular focus on the role of cultural competence when implementing EBTs. Specifically, we address three questions: (a) does psychotherapy work with ethnic minorities, (b) do psychotherapy effects differ by ethnicity, and (c) does cultural tailoring enhance treatment effects? The evidence suggests that psychotherapy is generally effective with ethnic minorities, and treatment effects are fairly robust across cultural groups and problem areas. However, evidence for cultural competence is mixed. Ethnic minority-focused treatments frequently incorporate culturally tailored strategies, and these tailored treatments are mostly efficacious; yet support for cultural competence as a useful supplement to standard treatment remains equivocal at best. We also discuss research limitations, areas for future research, and clinical implications.

  9. Nursing strategies to reduce the incidence of early childhood caries in culturally diverse populations.

    2011-06-01

    In the United States, early childhood caries (ECC) is a major unmet health care need adversely affecting the overall health of young children from diverse ethnic populations. Nurses who work in the newborn nursery, pediatrics, public, and community health centers have a unique opportunity to positively influence a change in this epidemic of ECC. Guided by Leininger's theory of cultural care, these authors describe ways to implement a comprehensive culturally sensitive oral health education program for parents of newborns and infants. Interventions based on the best available evidence for oral health education, a culturally sensitive caries risk assessment, recommendations for fluoride varnish treatments, and ways for parents to establish a dental home for the infant by 12 months old are presented.

    Sex-specific genetic structures have been previously documented worldwide in humans, even though causal factors have not always clearly been identified. In this study, we investigated the impact of ethnicity, geography and social organization on the sex-specific genetic structure in Inner Asia. Furthermore, we explored the process of ethnogenesis in multiple ethnic groups. We sampled DNA in Central and Northern Asia from 39 populations of Indo-Iranian and Turkic-Mongolic native speakers. We focused on genetic data of the Y chromosome and mitochondrial DNA. First, we compared the frequencies of haplogroups to South European and East Asian populations. Then, we investigated the genetic differentiation for eight Y-STRs and the HVS1 region, and tested for the effect of geography and ethnicity on such patterns. Finally, we reconstructed the male demographic history, inferred split times and effective population sizes of different ethnic groups. Based on the haplogroup data, we observed that the Indo-Iranian- and Turkic-Mongolic-speaking populations have distinct genetic backgrounds. However, each population showed consistent mtDNA and Y chromosome haplogroups patterns. As expected in patrilocal populations, we found that the Y-STRs were more structured than the HVS1. While ethnicity strongly influenced the genetic diversity on the Y chromosome, geography better explained that of the mtDNA. Furthermore, when looking at various ethnic groups, we systematically found a genetic split time older than historical records, suggesting a cultural rather than biological process of ethnogenesis. This study highlights that, in Inner Asia, specific cultural behaviors, especially patrilineality and patrilocality, leave a detectable signature on the sex-specific genetic structure. © 2017 Wiley Periodicals, Inc.

    Objective To understand the interrelationship of literacy, culture, and language and the importance of addressing their intersection. Methods Health literacy, cultural competence, and linguistic competence strategies to quality improvement were analyzed. Results Strategies to improve health literacy for low-literate individuals are distinct from strategies for culturally diverse and individuals with limited English proficiency (LEP). The lack of integration results in health care that is unresponsive to some vulnerable groups’ needs. A vision for integrated care is presented. Conclusion Clinicians, the health care team, and health care organizations have important roles to play in addressing challenges related to literacy, culture, and language. PMID:17931131

    Cultural diversity and its impact on mental health has become an increasingly important issue in a globalised world where the interactions between cultures continue to grow exponentially. This paper presents critical areas in which culture impacts on mental health, such as how health and illness are perceived, coping styles, treatment-seeking patterns, impacts of history, racism, bias and stereotyping, gender, family, stigma and discrimination. While cultural differences provide a number of challenges to mental health policy and practice they also provide a number of opportunities to work in unique and effective ways towards positive mental health. Ethno-specific approaches to mental health that incorporate traditional and community-based systems can provide new avenues for working with culturally diverse populations. © The Royal Australian and New Zealand College of Psychiatrists 2015.

    2010-01-01

    Populations represented by collections of points scattered randomly on the real line are ubiquitous in science and engineering. The statistical modeling of such populations leads naturally to Poissonian populations—Poisson processes on the real line with a distinguished maximal point. Poissonian populations are infinite objects underlying key issues in statistical physics, probability theory, and random fractals. Due to their infiniteness, measuring the diversity of Poissonian populations depends on the lower-bound cut-off applied. This research characterizes the classes of Poissonian populations whose diversities are invariant with respect to the cut-off level applied and establishes an elemental connection between these classes and extreme-value theory. The measures of diversity considered are variance and dispersion, Simpson’s index and inverse participation ratio, Shannon’s entropy and Rényi’s entropy, and Gini’s index.

    2005-04-01

    This paper describes a review of population health social marketing campaigns targeting culturally and linguistically diverse (CLD) communities in Australia in order to identify characteristics of effective CLD campaigns. Literature on CLD population health social marketing was identified from electronic searches of databases in August 2004. At the same time, the grey literature was examined by searching the Internet and talking to Australian experts in the fields of CLD social marketing and CLD research. Eight studies met the search criteria, four from the published literature. Two studies that employed prepost evaluation designs provided tentative support for the potential efficacy of CLD social marketing strategies. The remaining studies did not allow for causal attribution as they used post-campaign only or process evaluations. Studies did, however, show that CLD communities access campaign-related information from both mainstream and ethnic media channels. In addition, Vietnamese respondents were more likely to access campaign messages through ethnic radio and Chinese respondents through ethnic press. There is insufficient evidence to clearly identify the characteristics of effective CLD campaigns. Campaign evaluation designs used to evaluate social marketing strategies targeting CLD communities in Australia are generally weak, but there is tentative evidence supporting the potential efficacy of these strategies in some Australian settings.

    Full Text Available In the present study, we employed microsatellite DNA markers to analyze the genetic diversity and differentiation between and within cultured stocks and wild populations of the orange-spotted grouper originating from the South China Sea and Southeast Asia. Compared to wild populations, genetic changes including reduced genetic diversity and significant differentiation have taken place in cultured grouper stocks, as shown by allele richness and heterozygosity studies, pairwise Fst, structure, molecular variance analysis, as well as multidimensional scaling analysis. Although two geographically adjacent orange-spotted grouper populations in China showed negligible genetic divergence, significant population differentiation was observed in wild grouper populations distributed in a wide geographical area from China, through Malaysia to Indonesia. However, the Mantel test rejected the isolation-by-distance model of genetic structure, which indicated the genetic differentiation among the populations could result from the co-effects of various factors, such as historical dispersal, local environment, ocean currents, river flows and island blocks. Our results demonstrated that microsatellite markers could be suitable not only for genetic monitoring cultured stocks but also for revealing the population structuring of wild orange-spotted grouper populations. Meanwhile, our study provided important information for breeding programs, management of cultured stocks and conservation of wild populations of the orange-spotted grouper.

    McGinnis, Sandra L; Brush, Barbara L; Moore, Jean

    2010-11-01

    Proponents of health workforce diversity argue that increasing the number of minority health care providers will enhance cultural similarity between patients and providers as well as the health system's capacity to provide culturally competent care. Measuring cultural similarity has been difficult, however, given that current benchmarks of workforce diversity categorize health workers by major racial/ethnic classifications rather than by cultural measures. This study examined the use of national racial/ethnic categories in both patient and registered nurse (RN) populations and found them to be a poor indicator of cultural similarity. Rather, we found that cultural similarity between RN and patient populations needs to be established at the level of local labor markets and broadened to include other cultural parameters such as country of origin, primary language, and self-identified ancestry. Only then can the relationship between cultural similarity and cultural competence be accurately determined and its outcomes measured.

    2014-06-01

    Culturally and linguistically diverse (CALD) migrants face significant health risks as they adapt to new cultures. These risks are exacerbated by their limited participation in preventative behaviours such as sports and physical activity. The review aimed to identify studies that examined the correlates of sport and physical activity participation in migrants. The systematic review identified 72 papers, including 6 interventions, 18 qualitative and 48 quantitative studies. The 44 identified correlates highlight the complexities involved in working with migrants. The correlates were grouped in four themes using the social ecological model; acculturation, demographic, psychosocial and environmental/organisational. The social ecological model identified general correlates such as social support and safety. However, there were unique correlates relating to individuals who are facing cultural changes such as acculturation and language. Overall, there is a lack of contextualisation of CALD migrants' sport and physical activity experiences because many studies fail to consider acculturation comprehensively.

    Full Text Available This is a discussion paper which aims to contribute to the systematization of studies, concepts and practices on cultural policies which have been developed in previous years in Brazil and are orienting cultural actions and public programs in the country, also influencing the Occupational Therapy. Citizenship and Cultural Diversity are concepts under construction and are part of the of the agenda of cultural policies and as well as the reflections and practices of various occupational therapists who are acting in a constant dialogue with the cultural area by means of the formation in cultural management, cultural mapping, programs and grant projects aimed to promote inventive identities, traditional communities, native populations, urban mobility, and cultural networks and exchange initiatives, among others. The article presents the process of this conceptual construction and the constitution of experiences aiming the democratization of the culture in the history of Brazilian cultural public policies, over which are being discussed approach paths and possibilities for Occupational Therapy.

    Masu salmon,Oncorhynchus masou masou,is one of the most valuable fishery species that has been introduced to China,though to date no studies on the genetic diversity and genetic relationship among hatchery populations has been performed with molecular markers.We undertook such a study and sampled 120 individuals from three hatchery stocks and analyzed 20 microsatellite loci.All loci were polymorphic and a total of 91 alleles were detected.A relatively low level of genetic diversity was revealed with effective number of allele of 3.1094,3.3299 and 3.1894 and expected heterozygosity of 0.6600,0.6648 and 0.6638 in the three stocks,respectively.Deviations from Hardy-Weinberg equilibrium were found due to heterozygote deficit.Accordingly,evidence of genetic bottlenecks were found in the three stocks.An individual assignment test demonstrated that 85% of individuals were correctly assigned into their original stocks.Pairwise Fst revealed that significant differentiation occurred between these three stocks.The results of the study indicated that disequilibrium of genetic structure and differentiation has occurred in all three stocks.This information collectively provides a basis for measures to avoid of loss of genetic diversity and introgression in Chinese aquaculture.

    The complexity and variability of human culture is unmatched by any other species. Humans live in culturally constructed niches filled with artifacts, skills, beliefs, and practices that have been inherited, accumulated, and modified over generations. A causal account of the complexity of human culture must explain its distinguishing characteristics: It is cumulative and highly variable within and across populations. I propose that the psychological adaptations supporting cumulative cultural transmission are universal but are sufficiently flexible to support the acquisition of highly variable behavioral repertoires. This paper describes variation in the transmission practices (teaching) and acquisition strategies (imitation) that support cumulative cultural learning in childhood. Examining flexibility and variation in caregiver socialization and children's learning extends our understanding of evolution in living systems by providing insight into the psychological foundations of cumulative cultural transmission-the cornerstone of human cultural diversity.

    Full Text Available Occupational behaviour is always an environmental behaviour because the occupation is the dialogue between human beings and their environment. Culture is key dimension in our profession. This article is based on previous research and a new review of the scientific literature on the various meanings associated with culture. In the contemporary context the globalization involves the imposition of the American way of life on a planetary scale. In front of ethnocentrism and racism a diatopical hermeneutics is proposed. A cosmopolitan citizenship can be constructed supporting diversity. The article concludes by reflecting on strategies that can be implemented from occupational therapy to develop a culturally safe occupational therapy. An archaeology of meaning must be developed in front of the Americanization. Occupational therapy needs to develop a powerful political activism in order to build an inclusive society based on human rights and sustainability. Culture and diversity are key elements in this process.

    This article describes an expanded leadership role needed in schools of nursing as the nurse of the 21st century is prepared to assume expanded roles in a diverse society. With schools of nursing becoming more global, and the diverse population of the United States rapidly growing, a critical need exists for nurses who are ready to partner in the health care that multicultural communities need locally, nationally, and globally. Diversity and cultural competence have now become central issues in nursing education, research, practice, and health policy. Diversity leadership in a school of nursing can no longer concentrate only on issues of affirmative action, recruitment, and retention. The purpose of this article is to discuss how diversity leadership must increasingly focus on building a corporate environment in schools of nursing that integrates diversity and cultural competence with the strategic plan of the School's Chief Nursing Officer, across academic programs, research, practice, and public policy to eliminate health disparities in partnership with faculty, students, staff, the University infrastructure, and the community at large. The theoretical framework that guided the strategic planning is based on the model used by the Robert Wood Johnson Executive Nurse Fellowship Program. Examples of program initiatives designed to implement the strategic plan to strengthen the diversity and cultural competence of one school of nursing environment are described.

    In a climate of increasing diversity in the population of patients requiring physical therapy (PT) services, PT educators must prepare students and future clinicians to work competently in culturally diverse environments. To be able to achieve this goal, PT educators must be culturally competent as well. The purposes of the study were to develop a valid and reliable instrument to assess cultural diversity awareness and to develop an educational workshop to improve cultural diversity awareness of PT academic and clinical educators. Phase 1 of the study involved the development of an instrument to assess cultural diversity awareness. The Cultural Diversity Awareness Questionnaire (CDAQ) was developed, validated for content, analyzed for reliability, and field and pilot tested. Results indicated that the CDAQ has favorable psychometric properties. Phase 2 of the study involved the development and implementation of the Cultural Diversity Workshop (CDW). The seminar contents and class materials were developed, validated, and implemented as a one-day cultural diversity awareness seminar. A one-group, pretest-posttest experimental design was used, with participants who completed the CDAQ before and after the workshop. Results indicated that the workshop was effective in improving cultural diversity awareness of the participants. Results of the workshop evaluation affirmed the achievement of objectives and effectiveness of the facilitator. This study provided a solid initial foundation upon which a comprehensive cultural competence program can be developed.

    We review and summarize the findings across 7 studies contained in the special section titled, "Racial-Ethnic Socialization, Identity, and Youth Outcomes: Excavating Culture." These studies represent a significant advance for research in issues related to the impact of racial-ethnic socialization and identity on child outcomes. All 7 studies attempted to test in whole or part a hypothetical model in which ethnic-racial socialization in families of color is related to child psychosocial and academic outcomes directly and indirectly through effects on self-system variables such as racial-ethnic identity and self-esteem. Two types of racial socialization messages were of particular interest: messages that promote cultural pride (referred to as ethnic or cultural socialization) and messages that address children's exposure to discrimination (referred to as racial socialization). Collectively, the studies suggest that ethnic-racial socialization processes are related to youth outcomes through indirect associations with ethnic-racial identity and self-esteem. Findings were most consistent in the studies with African American youth and some aspects of the model were not supported for American Indian and Chinese youth. Ethnic and racial group differences and directions for future research are discussed.

    Using established criteria for work with fossil DNA we have analysed mitochondrial DNA from 92 individuals from 18 locations in Denmark ranging in time from the Mesolithic to the Medieval Age. Unequivocal assignment of mtDNA haplotypes was possible for 56 of the ancient individuals; however, the success rate varied substantially between sites; the highest rates were obtained with untouched, freshly excavated material, whereas heavy handling, archeological preservation and storage for many years influenced the ability to obtain authentic endogenic DNA. While the nucleotide diversity at two locations was similar to that among extant Danes, the diversity at four sites was considerably higher. This supports previous observations for ancient Britons. The overall occurrence of haplogroups did not deviate from extant Scandinavians, however, haplogroup I was significantly more frequent among the ancient Danes (average 13%) than among extant Danes and Scandinavians (approximately 2.5%) as well as among other ancient population samples reported. Haplogroup I could therefore have been an ancient Southern Scandinavian type "diluted" by later immigration events. Interestingly, the two Neolithic samples (4,200 YBP, Bell Beaker culture) that were typed were haplogroup U4 and U5a, respectively, and the single Bronze Age sample (3,300-3,500 YBP) was haplogroup U4. These two haplogroups have been associated with the Mesolithic populations of Central and Northern Europe. Therefore, at least for Southern Scandinavia, our findings do not support a possible replacement of a haplogroup U dominated hunter-gatherer population by a more haplogroup diverse Neolithic Culture.

  20. An administrative concern: Science teachers' instructional efficacy beliefs regarding racially, culturally, economically, and linguistically diverse student populations

    Tuck Bonner, Natalie Christine

    A teacher's sense of {instructional} efficacy has been considered a critical variable in student academic performance. Researchers Tschannen-Moran and Hoy Woolfolk (2001, p.783) defined teachers' {instructional} efficacy as a teacher's judgment of his or her capabilities to bring about desired outcomes of student engagement and learning, even among those students who may be difficult or unmotivated. There has been a substantial amount of research which reveals a strong correlation among teacher efficacy, teaching performance, and student achievement (Goddard & Goddard, et.al., 2000; Hackett; Hackett, 1995; Pajares, 1997 as cited in Villereal, 2005). This research study explored the content area of science and teacher's personal perception of their competency level in teaching science to all learners regardless of socio-economic, ethnicity/race or gender for grade levels Pre-K to 12. Lewthwaite states that a science teacher's personal teacher attributes or intrinsic factors such as science teaching self-efficacy, professional science knowledge, science teaching, instructional methodologies, interest in science, and motivation to teach science are critical dimensions and noted barriers in the delivery of science programs on elementary level campuses (Lewthwaite, Stableford & Fisher, 2001). This study focused on teacher instructional efficacy issues which may affect diverse learners' classroom and state-mandated assessment academic performance outcomes. A SPSS analysis of data was obtained from the following teacher survey instruments: The Bandura Teacher Efficacy Scale, the SEBEST, and the SETAKIST. Research findings revealed that a majority of science teachers surveyed believe they can effectively teach learners of diverse backgrounds, but responded with a sense of lower efficaciousness in teaching English Language Learners. There was also a statistically significant difference found between a state science organization and a national science organization

  1. Population genetic diversity and fitness in multiple environments

    Full Text Available Abstract Background When a large number of alleles are lost from a population, increases in individual homozygosity may reduce individual fitness through inbreeding depression. Modest losses of allelic diversity may also negatively impact long-term population viability by reducing the capacity of populations to adapt to altered environments. However, it is not clear how much genetic diversity within populations may be lost before populations are put at significant risk. Development of tools to evaluate this relationship would be a valuable contribution to conservation biology. To address these issues, we have created an experimental system that uses laboratory populations of an estuarine crustacean, Americamysis bahia with experimentally manipulated levels of genetic diversity. We created replicate cultures with five distinct levels of genetic diversity and monitored them for 16 weeks in both permissive (ambient seawater and stressful conditions (diluted seawater. The relationship between molecular genetic diversity at presumptive neutral loci and population vulnerability was assessed by AFLP analysis. Results Populations with very low genetic diversity demonstrated reduced fitness relative to high diversity populations even under permissive conditions. Population performance decreased in the stressful environment for all levels of genetic diversity relative to performance in the permissive environment. Twenty percent of the lowest diversity populations went extinct before the end of the study in permissive conditions, whereas 73% of the low diversity lines went extinct in the stressful environment. All high genetic diversity populations persisted for the duration of the study, although population sizes and reproduction were reduced under stressful environmental conditions. Levels of fitness varied more among replicate low diversity populations than among replicate populations with high genetic diversity. There was a significant correlation

    Much of the migrant workforce in Qatar is of low literacy level and does not understand Arabic or English, presenting a significant challenge to health care professionals. Medicine labels are typically in Arabic and English and are therefore poorly understood by these migrant workers. To develop pictograms illustrating selected medicine label instructions and to evaluate comprehension of the pictograms or conventional text supported with verbal instructions in foreign workers with low literacy skills. A range of common labeling instructions were identified and pictograms depicting these were developed using visual concepts and ideas from the literature. The process involved a consultative approach with input from the researchers, a local graphic artist, and members of the target population. The final set was evaluated for comprehension in participants who were randomized to one of three study groups: text plus verbal instructions, pictogram-only label, and pictogram with verbal instructions. One-way ANOVA and Chi-square tests were used to assess differences between group variables. Statistical significance was set at P ≤ 0.05. Of 23 label instructions screened, 11 were selected for the study. A total of 123 participants took part in this study. Pictogram plus verbal instructions group achieved better results in interpreting the majority of the label instructions (P ≤ 0.05). The best interpreted pictograms with verbal instructions included: "Take two tablets three times a day," "Take one tablet in the morning and one tablet at night," and "Instill one drop in the eye." The worst interpreted pictograms with verbal instructions were: "Do not take with dairy products" and "Do not use by mouth." Some pictograms were difficult to interpret even when accompanied with verbal instructions, suggesting the need to thoroughly pilot them among users prior to implementation. Medication labels consisting of simple pictorials supported by verbal instructions were better

  7. Song diversity predicts the viability of fragmented bird populations.

    Paola Laiolo

    Full Text Available In the global scenario of increasing habitat fragmentation, finding appropriate indicators of population viability is a priority for conservation. We explored the potential of learned behaviours, specifically acoustic signals, to predict the persistence over time of fragmented bird populations. We found an association between male song diversity and the annual rate of population change, population productivity and population size, resulting in birds singing poor repertoires in populations more prone to extinction. This is the first demonstration that population viability can be predicted by a cultural trait (acquired via social learning. Our results emphasise that cultural attributes can reflect not only individual-level characteristics, but also the emergent population-level properties. This opens the way to the study of animal cultural diversity in the increasingly common human-altered landscapes.

    Background. Social scientists have suggested that cultural diversity in a nation leads to societal instability. However, societal instability may be affected not only by within-nation on ?? diversity, but also diversity between a nation and its neighbours or ?? diversity. It is also necessary to distinguish different domains of diversity, namely linguistic, ethnic and religious, and to distinguish between the direct effects of diversity on societal instability, and effects that are mediated by economic conditions. Methodology/Principal Findings. We assembled a large cross-national dataset with information on ?? and ?? cultural diversity, economic conditions, and indices of societal instability. Structural equation modeling was used to evaluate the direct and indirect effects of cultural diversity on economics and societal stability. Results show that different type and domains of diversity have interacting effects. As previously documented, linguistic ?? diversity has a negative effect on economic performance, and we show that it is largely through this economic mechanism that it affects societal instability. For ?? diversity, the higher the linguistic diversity among nations in a region, the less stable the nation. But, religious ?? diversity has the opposite effect, reducing instability, particularly in the presence of high linguistic diversity. Conclusions. Within-nation linguistic diversity is associated with reduced economic performance, which, in turn, increases societal instability. Nations which differ linguistically from their neighbors are also less stable. However, religious diversity between, neighboring nations has the opposite effect, decreasing societal instability.

  11. Ethical aspects of genome diversity research: genome research into cultural diversity or cultural diversity in genome research?

    2009-03-01

    The goal of the Human Genome Diversity Project (HGDP) was to reconstruct the history of human evolution and the historical and geographical distribution of populations with the help of scientific research. Through this kind of research, the entire spectrum of genetic diversity to be found in the human species was to be explored with the hope of generating a better understanding of the history of humankind. An important part of this genome diversity research consists in taking blood and tissue samples from indigenous populations. For various reasons, it has not been possible to execute this project in the planned scope and form to date. Nevertheless, genomic diversity research addresses complex issues which prove to be highly relevant from the perspective of research ethics, transcultural medical ethics, and cultural philosophy. In the article at hand, we discuss these ethical issues as illustrated by the HGDP. This investigation focuses on the confrontation of culturally diverse images of humans and their cosmologies within the framework of genome diversity research and the ethical questions it raises. We argue that in addition to complex questions pertaining to research ethics such as informed consent and autonomy of probands, genome diversity research also has a cultural-philosophical, meta-ethical, and phenomenological dimension which must be taken into account in ethical discourses. Acknowledging this fact, we attempt to show the limits of current guidelines used in international genome diversity studies, following this up by a formulation of theses designed to facilitate an appropriate inquiry and ethical evaluation of intercultural dimensions of genome research.

    As the population demographics for the United States (U.S.) shift towards increasing diversity, it is essential that nurses provide culturally competent care. Cultural sensitivity has been identified as a major curricular element in the American Association of Colleges of Nursing's (AACN) The Essentials of Baccalaureate Education for Professional Nursing Practice. Thus it is imperative that nursing faculty use effective strategies to help nursing students develop cultural sensitivity and competence. Educational workshops focusing on cultural diversity are usually designed to increase people's cultural sensitivity. The purpose of this study was to assess the effectiveness of a cultural diversity forum on nursing students' cultural sensitivity as measured by their openness to diversity. A convenience sample of students was recruited from a public university in the southeastern United States. The workshop was designed as a forum that combined a keynote presentation, shared meal, and a small group interactional activity. Cultural sensitivity was measured using the Openness to Diversity/Challenge Scale (ODCS), and was administered to students before and after the forum. A convenience sample of 47 students agreed to participate and completed both the pretest and posttest. Following the workshop, the students had more cultural sensitivity as measured by their scores on the ODCS (Wilcoxin Signed-Rank test z= -3.286, p = 0.001). The findings suggested that an educational format like the cultural diversity forum can promote students' cultural sensitivity. Further research needs to continue to focus on the effectiveness of strategies to increase the cultural sensitivity of baccalaureate nursing students.

    Human cultural traits, such as languages, musics, rituals and material objects, vary widely across cultures. However, the majority of comparative analyses of human cultural diversity focus on between-culture variation without consideration for within-culture variation. In contrast, biological approaches to genetic diversity, such as the analysis of molecular variance (AMOVA) framework, partition genetic diversity into both within- and between-population components. We attempt here for the first time to quantify both components of cultural diversity by applying the AMOVA model to music. By employing this approach with 421 traditional songs from 16 Austronesian-speaking populations, we show that the vast majority of musical variability is due to differences within populations rather than differences between. This demonstrates a striking parallel to the structure of genetic diversity in humans. A neighbour-net analysis of pairwise population musical divergence shows a large amount of reticulation, indicating the pervasive occurrence of borrowing and/or convergent evolution of musical features across populations.

    Down syndrome is the most common cause of cognitive impairment and presents clinically with universally recognizable signs and symptoms. In this study, we focus on exam findings and digital facial analysis technology in individuals with Down syndrome in diverse populations. Photos and clinical information were collected on 65 individuals from 13 countries, 56.9% were male and the average age was 6.6 years (range 1 month to 26 years; SD = 6.6 years). Subjective findings showed that clinical features were different across ethnicities (Africans, Asians, and Latin Americans), including brachycephaly, ear anomalies, clinodactyly, sandal gap, and abundant neck skin, which were all significantly less frequent in Africans (P Down syndrome with a sensitivity of 0.961, specificity of 0.924, and accuracy of 0.943. Only the angles at medial canthus and ala of the nose were common significant findings amongst different ethnicities (Caucasians, Africans, and Asians) when compared to ethnically matched controls. The Asian group had the least number of significant digital facial biometrics at 4, compared to Caucasians at 8 and Africans at 7. In conclusion, this study displays the wide variety of findings across different geographic populations in Down syndrome and demonstrates the accuracy and promise of digital facial analysis technology in the diagnosis of Down syndrome internationally. © 2016 Wiley Periodicals, Inc.

    Whitehead, Hal; Lusseau, David

    2012-02-07

    We used individual-based stochastic models to examine how social structure influences the diversity of socially learned behaviour within a non-human population. For continuous behavioural variables we modelled three forms of dyadic social learning, averaging the behavioural value of the two individuals, random transfer of information from one individual to the other, and directional transfer from the individual with highest behavioural value to the other. Learning had potential error. We also examined the transfer of categorical behaviour between individuals with random directionality and two forms of error, the adoption of a randomly chosen existing behavioural category or the innovation of a new type of behaviour. In populations without social structuring the diversity of culturally transmitted behaviour increased with learning error and population size. When the populations were structured socially either by making individuals members of permanent social units or by giving them overlapping ranges, behavioural diversity increased with network modularity under all scenarios, although the proportional increase varied considerably between continuous and categorical behaviour, with transmission mechanism, and population size. Although functions of the form e(c)¹(m)⁻(c)² + (c)³(Log(N)) predicted the mean increase in diversity with modularity (m) and population size (N), behavioural diversity could be highly unpredictable both between simulations with the same set of parameters, and within runs. Errors in social learning and social structuring generally promote behavioural diversity. Consequently, social learning may be considered to produce culture in populations whose social structure is sufficiently modular.

    Although many environmental microbial populations are large and genetically diverse, both the level of diversity and the extent to which it is ecologically relevant remain enigmatic. Because the effective (or long-term) population size, N(e), is one of the parameters that determines population genetic diversity, tests and simulations that assume selectively neutral mutations may help to identify the processes that have shaped microbial diversity. Using ecologically important genes, tests of selective neutrality suggest that adaptive as well as non-adaptive types of selection act and that departure from neutrality may be widespread or restricted to small groups of genotypes. Population genetic simulations using population sizes between 10(3) and 10(7) suggest extremely high levels of microbial diversity in environments that sustain large populations. However, census and effective population sizes may differ considerably, and because we know nothing of the evolutionary history of environmental microbial populations, we also have no idea what N(e) of environmental populations is. On the one hand, this reflects our ignorance of the microbial world. On the other hand, the tests and simulations illustrate interactions between microbial diversity and microbial population genetics that should inform our thinking in microbial ecology. Because of the different views on microbial diversity across these disciplines, such interactions are crucial if we are to understand the role of genes in microbial communities.

    Cultural diversity is a strength of the American work force. Due to the increasing cultural diversity in the workplace, organizations find it in their best interest to move beyond affirmative action to effective management to achieve higher employee retention and develops an employee cultural mix that better matches the mix of the available labor force and customer base. To manage a diverse work force, managers need to have the proper tools, training and evaluation and monitoring programs. Important initiatives to successful management of cultural diversity include eliciting support and commitment from the board of directors, the CEO and other top management; organizing subcommittees to research and monitor demographic changes to determine what the organization's goals should be and to decide what changes are to be made.

    2011-07-01

    Full Text Available The acceptance and management of cultural diversity have been promoted and touted as a positive tool in social and organizational engineering aimed at solving and preventing group dynamics problems in both business organizations and society as well. Positive attributes of cultural integration in business organizations have received fair and significant attention in the past two decades. What have not been sufficiently presented are the challenges and pitfalls inherent in the management of culturally diverse work groups. For the practicing manager, there is a need to know when and where mono- and multi-cultural arrangements may be preferred. This paper reviews relevant research findings that can be used for building effective paradigms in the management of cultural diversity in the workplace.

  2. Diversity disorders: Ethnicity and newsroom cultures

    Directory of Open Access Journals (Sweden)

    Gunilla Hultén

    2009-10-01

    Full Text Available Sweden, as many other European countries, has been engaged in the debate concerning the relationships between social cohesion and the media. The article examines the tension between officially expressed attitudes and diversity goals of Swedish newsrooms and how journalists who have foreign backgrounds perceive these. Despite the intense discussions in recent years concerning media's role in a multi-ethnic context Swedish media organizations have not yet developed an effective means of promoting and implementing diversity in the newsrooms. The interviewed journalists draw attention to the dilemma of not being accepted in majority dominated newsrooms and stress the need to change editorial organization patterns, newsroom cultures and to re-define journalistic missions regarding ethnic diversity. The article concerns the market focus of news production and argues that the present tendency to mainstream cultural diversity in media content may lead to the exclusion of minority voices and thus undermining diversity efforts.

    Full Text Available We describe an anthropological and interdisciplinary field school, primary involving female undergraduates. Our field program was conducted in 2009 and 2010 on a remote island in Fijian archipelago, in the context of a patriarchal society where gender avoidance is practiced. We had two broad objectives for this program: to conduct research on the understanding of cultural and marine biological resources; and to evaluate the effectiveness of the field experience in promoting anthropological and scientific learning principles. We summarize qualitative and quantitative outcomes of the educational evaluation of the student learning experience. We also discuss educational aims and the unique gender-associated challenges of conducting this program in a patriarchal cultural setting.

    This two hour special workshop was held during the 2012 ASP conference in Tucson. There are a variety of reasons that science education needs to reach out to culturally diverse audiences. Each culture, and each individual community, has its own challenges; each brings special insight to science. What does the research say about engaging these different audiences? How can science educators attract and sustain programs with various cultures? How do the needs of our audiences vary with culture and within communities? Moderators Shupla, Sanlyn, and Peticolas invited a variety of presenters with expertise to share their experiences: Salvador Acevado, David Begay, Michelle Higgins, Bryan Mendez, and Dara Norman. During the first hour, presenters shared a variety of best practices for engaging and supporting culturally diverse audiences; in the second hour, participants and presenters discussed specific programmatic challenges and possible directions.

    Quick, Virginia M; Byrd-Bredbenner, Carol

    2014-01-01

    This study examined disordered eating, socio-cultural media influencers, body image, and psychological factors among a large, racially/ethnically diverse sample of college women (n=1445; 58% White, 21% Asian, 11% Hispanic, 11% Black) who completed an online survey. Black women were significantly more satisfied with their weight and shape and had lower eating concerns, disinhibited eating, and emotional eating than all other racial/ethnic groups. Black women tended to have significantly higher levels of self-esteem, were less likely to compare their body to those of people in the media, felt less pressured to attain the physical appearance standard set by the media, and had less awareness of the societal appearance norms set by the media than other racial groups. Findings suggest that Black college women, independent of weight status, may be protected from disordered eating, negative body image, and societal media pressures. © 2013.

    This study begins by presenting the notion of "technoscience" in relation to Modernity and Postmodernity. It proceeds with an argument in support of the real and potential contributions of technoscience for the preservation and promotion of diversity (cultural, technological and natural) in the context of globalization. It concludes by raising the important ethical issue that is eluded in the far too often postmodern esthetic approach: diversity should not be appropriated to inequality and discrimination.

    Lequerica, Anthony; Krch, Denise

    2014-01-01

    With the general population in the United States becoming increasingly diverse, it is important for rehabilitation professionals to develop the capacity to provide culturally sensitive treatment. This is especially relevant when working with minority populations who have a higher risk for brain injury and poorer rehabilitation outcomes. This article presents a number of clinical vignettes to illustrate how cultural factors can influence behavior in patients recovering from brain injury, as well as rehabilitation staff. The main objectives are to raise awareness among clinicians and stimulate research ideas by highlighting some real world examples of situations where a specialized, patient-centered approach needs to consider factors of cultural diversity. Because one's own world view impacts the way we see the world and interpret behavior, it is important to understand one's own ethnocentrism when dealing with a diverse population of patients with brain injury where behavioral sequelae are often expected. Being able to see behavior after brain injury with an open mind and taking into account cultural and contextual factors is an important step in developing culturally competent rehabilitation practices.

    2012-01-01

    When selection increases the frequency of a beneficial gene substitution it can also increase the frequencies of linked neutral alleles through a process called genetic hitchhiking.A model built to investigate reduced genetic diversity in Pleistocene hominins shows that genetic hitchhiking can have a strong effect on neutral diversity in the presence of culturally mediated migration.Under conditions in which genetic and cultural variants are transmitted symmetrically,neutral genes may also hitchhike to higher frequencies on the coattails of adaptive cultural traits through a process called cultural hitchhiking.Cultural hitchhiking has been proposed to explain why some species of matrilineal whales display relatively low levels of mitochondrial DNA diversity,and it may be applicable to humans as well.This paper provides a critical review of recent models of both types of hitchhiking in socially structured populations.The models' assumptions and predictions are compared and discussed in the hope that studies of reduced genetic diversity in humans might improve our understanding of reduced genetic diversity in other species,and vice versa [Current Zoology 58 (1):287-297,2012].

    Incorporating culture into an expanded theory of evolution will provide the foundation for a universal account of human diversity. Two requirements must be met. The first is to see learning as an extension of the processes of evolution. The second is to understand that there are specific components of human culture, viz. higher order knowledge structures and social constructions, which give rise to culture as invented knowledge. These components, which are products of psychological processes and mechanisms, make human culture different from the forms of shared knowledge observed in other species. One serious difficulty for such an expanded theory is that social constructions may not add to the fitness of all humans exposed to them. This may be because human culture has existed for only a relatively short time in evolutionary terms. Or it may be that, as some maintain, adaptation is a limited, even a flawed, aspect of evolutionary theory.

The papers in this Theme Issue, which derives from a symposium held by the AHRC Centre for the Evolution of Cultural Diversity (University College London) in December 2008, focus on how the phylogenetic tree-building and network-based techniques used to estimate descent relationships in biology can be adapted to reconstruct cultural histories, where some degree of inter-societal diffusion will almost inevitably be superimposed on any deeper signal of a historical branching process. The disciplines represented include the three most purely 'cultural' fields from the four-field model of anthropology (cultural anthropology, archaeology and linguistic anthropology). In this short introduction, some context is provided from the history of anthropology, and key issues raised by the papers are highlighted.

    In Australia, where about 16% of young people are born overseas and 24% are from a non-English-speaking background, adolescent health care is a multicultural challenge. "Cultural competency" involves challenging one's own cultural assumptions and beliefs, developing empathy for people from other cultures, and applying specific communication and interaction skills in clinical encounters. For health professionals, sensitivity to the cultural, ethnic, linguistic and social diversity among young people helps to avert problems and misunderstandings, improves satisfaction for all concerned and leads to better outcomes. Engaging the family and gaining the trust of parents is critical in treating young people from cultural backgrounds in which participation in health care is a family concern rather than an individual responsibility.

    The patient population served by orthopaedic surgeons is becoming increasingly more diverse, but this is not yet reflected in our workforce. As the cultural diversity of our patient population grows, we must be adept at communicating with patients of all backgrounds. WHERE ARE WE NOW?: Efforts to improve the diversity of our workforce have been successful in increasing the number of female residents, but there has been no improvement in the number of African American and Hispanic residents. There is currently no centralized effort to recruit minority and female students to the specialty of orthopaedic surgery. The American Academy of Orthopaedic Surgeons has been leading workshops to train residents and practicing surgeons in communication skills and cultural competency. WHERE DO WE NEED TO GO?: We must train the current generation of orthopaedic surgeons to become adept at interacting with patients of all backgrounds. While initiatives for crosscultural communication in orthopaedic surgery have been established, they have not yet been universally incorporated into residency training and Continuing Medical Education programs. HOW DO WE GET THERE?: We must continue to recruit the brightest students of all backgrounds, with a concerted effort to provide equal opportunities for early guidance to all trainees. Opportunities to improve diversity among orthopaedic surgeons exist at many stages in a future physician's career path, including "shadowing" in high school and college and continuing with mentorship in medical school. Additional resources should be dedicated to teaching residents about the immediate relevancy of cultural competency, and faculty should model these proficiencies during their patient interactions.

    One current challenge in microbial ecology is elucidating the functional roles of the large diversity of free-living and host-associated bacteria identified by culture-independent molecular methods. Importantly, the characterization of this immense bacterial diversity will likely require merging data from culture-independent approaches with work on bacterial isolates in culture. Amphibian skin bacterial communities have become a recent focus of work in host-associated microbial systems due to the potential role of these skin bacteria in host defense against the pathogenic fungus Batrachochytrium dendrobatidis (Bd), which is associated with global amphibian population declines and extinctions. As there is evidence that some skin bacteria may inhibit growth of Bd and prevent infection in some cases, there is interest in using these bacteria as probiotic therapy for conservation of at-risk amphibians. In this study, we used skin swabs from American toads (Anaxyrus americanus) to: (1) assess the diversity and community structure of culturable amphibian skin bacteria grown on high and low nutrient culture media, (2) determine which culture media recover the highest proportion of the total skin bacterial community of individual toads relative to culture-independent data, and (3) assess whether the plated communities from the distinct media types vary in their ability to inhibit Bd growth in in-vitro assays. Overall, we found that culture media with low nutrient concentrations facilitated the growth of more diverse bacterial taxa and grew distinct communities relative to media with higher nutrient concentrations. Use of low nutrient media also resulted in culturing proportionally more of the bacterial diversity on individual toads relative to the overall community defined using culture-independent methods. However, while there were differences in diversity among media types, the variation among individual hosts was greater than variation among media types, suggesting that

    2016-01-01

    Culturally transmitted behavior can be structured in its performance both geographically and temporally, in terms of where and when implements are made and used on the landscape (what Ingold calls “the taskscape”). Yet cultural transmission theory has not yet explored the consequences of behaviors transmitted differently due to their enactment at different taskscape locations, what Tostevin calls “taskscape visibility.” Here, we use computer simulations to explore how taskscape visibility and forager mobility affect the diversity of two selectively neutral culturally transmitted traits within a single population of social learners. The trait that can be transmitted from residential bases only (lower taskscape visibility) shows greater diversity than the trait that can be transmitted from residential bases and logistical camps (higher taskscape visibility). In addition, increased logistical mobility has a positive effect on the diversity of the trait with the lower taskscape visibility while it generally shows little to no effect on the diversity of the trait with higher taskscape visibility. Without an appreciation for the ways in which taskscape visibility and mobility can structure cultural transmission in space and through time, the difference in the observed equilibrium diversity levels of the two traits might be incorrectly interpreted as resulting from qualitatively different forms of biased cultural transmission. The results of our simulation experiment suggest that researchers may need to take the taskscape visibility into account when inferring cultural transmission from archaeological data. PMID:27583682

    Young, Susan; Guo, Kristina L

    2016-01-01

    The purpose of this article is to discuss the need to provide culturally sensitive care to the growing number of diverse health care consumers. A literature review of national standards and research on cultural competency was conducted and specifically focused on the field of nursing. This study supports the theory that cultural competence is learned over time and is a process of inner reflection and awareness. The domains of awareness, skill, and knowledge are essential competencies that must be gained by health care providers and especially for nurses. Although barriers to providing culturally sensitive care exist, gaining a better understanding of cultural competence is essential to developing realistic education and training techniques, which will lead to quality professional nursing practice for increasingly diverse populations.

Participants: 481 adults from Argentina (52.8% female, 47.2% male; age average = 35.45 years old. Instruments: Intergroup Anxiety scale, Cultural Sensitivity scale, and an ad hoc protocol designed to assess level of effectiveness perception in socio-culturally diverse leaders. Results: Differences in the level of perception of effectiveness according to sociocultural characteristics could not be confirmed. However, a direct effect of cultural sensitivity and an indirect effect of intergroup anxiety on the levels of effectiveness perception were confirmed. This work contributes to previous studies on prejudice and leadership.

    Despite a burgeoning science of cultural evolution, relatively little work has focused on the population structure of human cultural variation. By contrast, studies in human population genetics use a suite of tools to quantify and analyse spatial and temporal patterns of genetic variation within and between populations. Human genetic diversity can be explained largely as a result of migration and drift giving rise to gradual genetic clines, together with some discontinuities arising from geographical and cultural barriers to gene flow. Here, we adapt theory and methods from population genetics to quantify the influence of geography and ethnolinguistic boundaries on the distribution of 700 variants of a folktale in 31 European ethnolinguistic populations. We find that geographical distance and ethnolinguistic affiliation exert significant independent effects on folktale diversity and that variation between populations supports a clustering concordant with European geography. This pattern of geographical clines and clusters parallels the pattern of human genetic diversity in Europe, although the effects of geographical distance and ethnolinguistic boundaries are stronger for folktales than genes. Our findings highlight the importance of geography and population boundaries in models of human cultural variation and point to key similarities and differences between evolutionary processes operating on human genes and culture.

    In this paper we apply reaction-diffusion models to explore the relationship between the rate of behavioural innovation and the level of cultural diversity. We investigate how both independent invention and the modification and refinement of established innovations impact on cultural dynamics and diversity. Further, we analyse these relationships in the presence of biases in cultural learning and find that the introduction of new variants typically increases cultural diversity substantially in the short term, but may decrease long-term diversity. Independent invention generally supports higher levels of cultural diversity than refinement. Repeated patterns of innovation through refinement generate characteristic oscillating trends in diversity, with increasing trends towards greater average diversity observed for medium but not low innovation rates. Conformity weakens the relationship between innovation and diversity. The level of cultural diversity, and pattern of temporal dynamics, potentially provide clues as to the underlying process, which can be used to interpret empirical data.

    The link between cultural diversity and human rights was clearly established by the Universal Declaration on Cultural Diversity, adopted by the member states of UNESCO in 2001, which holds that "the defence of cultural diversity is … inseparable from respect for human dignity" and that it "implies a commitment to human rights and fundamental freedoms." The UNESCO Convention on the Protection and Promotion of the Diversity of Cultural Expressions, adopted in 2005, states that "cultural diversity can be protected and promoted only if human rights and fundamental freedoms … are guaranteed" (Article 2[1]). The precise relationship between cultural diversity and human rights, however, is not clarified and thus leaves room for further exploration. This contribution analyses the issues surrounding the relationship between cultural diversity and human rights, in particular cultural rights. Firstly, it addresses general human rights issues such as universality and cultural relativism and the principles of equality and non-discrimination. Secondly, it explores the scope of cultural rights, as well as the cultural dimension of human rights. Thirdly, several cases are discussed in which human rights were invoked to protect cultural interests, confirming the value of cultural diversity. Finally, some concluding remarks are presented, indicating which areas require attention in order to further improve the promotion and protection of human rights in relation to cultural diversity.

    Declines in migratory species are a pressing concern worldwide, but the mechanisms underpinning these declines are not fully understood. We hypothesised that species with greater within-population variability in migratory movements and destinations, here termed 'migratory diversity', might be more resilient to environmental change. To test this, we related map-based metrics of migratory diversity to recent population trends for 340 European breeding birds. Species that occupy larger non-breeding ranges relative to breeding, a characteristic we term 'migratory dispersion', were less likely to be declining than those with more restricted non-breeding ranges. Species with partial migration strategies (i.e. overlapping breeding and non-breeding ranges) were also less likely to be declining than full migrants or full residents, an effect that was independent of migration distance. Recent rates of advancement in Europe-wide spring arrival date were greater for partial migrants than full migrants, suggesting that migratory diversity may also help facilitate species responses to climate change. © 2016 John Wiley & Sons Ltd/CNRS.

    Sudden oak death, the tree disease caused by Phytophthora ramorum, has significant environmental and economic impacts on natural forests on the U.S. west coast, plantations in the United Kingdom, and in the worldwide nursery trade. Stream baiting is vital for monitoring and early detection of the pathogen in high-risk areas and is performed routinely; however, little is known about the nature of water-borne P. ramorum populations. Two drainages in an infested California forest were monitored intensively using stream-baiting for 2 years between 2009 and 2011. Pathogen presence was determined both by isolation and polymerase chain reaction (PCR) from symptomatic bait leaves. Isolates were analyzed using simple sequence repeats to study population dynamics and genetic structure through time. Isolation was successful primarily only during spring conditions, while PCR extended the period of pathogen detection to most of the year. Water populations were extremely diverse, and changed between seasons and years. A few abundant genotypes dominated the water during conditions considered optimal for aerial populations, and matched those dominant in aerial populations. Temporal patterns of genotypic diversification and evenness were identical among aerial, soil, and water populations, indicating that all three substrates are part of the same epidemiological cycle, strongly influenced by rainfall and sporulation on leaves. However, there was structuring between substrates, likely arising due to reduced selection pressure in the water. Additionally, water populations showed wholesale mixing of genotypes without the evident spatial autocorrelation present in leaf and soil populations.

  1. Different Regional Approaches to Cultural diversity Interpreting the Belgian Cultural Diversity Policy Paradox

    2015-11-01

    Full Text Available In Belgium, the authority over cultural diversity policies resulting from immigration has been devolved from the central state to the regions since 1970. Consequently, Flanders and Francophone Belgium have progressively developed divergent policy tools. By describing the divergent evolution of Francophone and Flemish cultural diversity policies, our paper demonstrates the existence of a “Belgian Cultural Diversity Paradox”, namely the existence of more multicultural minority rights in the region that has most experienced electoral success by an extreme-right anti-immigrant party (Flanders, and a more colour blind and radical secular approach in the region where anti-immigrant politicization is barely a factor (Francophone Belgium. This finding is counter-intuitive because an important strand of immigrant policy research has emphasized the relationship between the politicization of immigration and restrictive immigrant citizenship rights. Our paper demonstrates that the different degrees of politicization of immigration in Flanders and Francophone Belgium cannot fully account for divergent cultural diversity policies. By insisting on the historical path dependency of the linguistic and religious cleavages in Belgium and their overlap, this paper offers an addendum to the politicization approach. The historical linguistic and religious differences of the Belgian regions clearly mediate the impact of the politicization of immigration on both sides of the linguistic border.

    2016-01-01

    In a connected world where people influence each other, what can cause a globalized monoculture, and which measures help to preserve the coexistence of cultures? Previous research has shown that factors such as homophily, population size, geography, mass media, and type of social influence play important roles. In the present paper, we investigate for the first time the impact that institutions have on cultural diversity. In our first three studies, we extend existing agent-based models and explore the effects of institutional influence and agent loyalty. We find that higher institutional influence increases cultural diversity, while individuals' loyalty to their institutions has a small, preserving effect. In three further studies, we test how bottom-up and top-down processes of institutional influence impact our model. We find that bottom-up democratic practices, such as referenda, tend to produce convergence towards homogeneity, while top-down information dissemination practices, such as propaganda, further increase diversity. In our last model--an integration of bottom-up and top-down processes into a feedback loop of information--we find that when democratic processes are rare, the effects of propaganda are amplified, i.e., more diversity emerges; however, when democratic processes are common, they are able to neutralize or reverse this propaganda effect. Importantly, our models allow for control over the full spectrum of diversity, so that a manipulation of our parameters can result in preferred levels of diversity, which will be useful for the study of other factors in the future. We discuss possible mechanisms behind our results, applications, and implications for political and social sciences.

  4. Social experience does not abolish cultural diversity in eye movements

    David J Kelly

    2011-05-01

    Full Text Available Adults from Eastern (e.g., China and Western (e.g., USA cultural groups display pronounced differences in a range of visual processing tasks. For example, the eye movement strategies used for information extraction during a variety of face processing tasks (e.g., identification and facial expressions of emotion categorization differs across cultural groups. Currently, many of the differences reported in previous studies have asserted that culture itself is responsible for shaping the way we process visual information, yet this has never been directly investigated. In the current study, we assessed the relative contribution of genetic and cultural factors by testing face processing in a population of British Born Chinese (BBC adults using face recognition and expression classification tasks. Contrary to predictions made by the cultural differences framework, the majority of BBC adults deployed ‘Eastern’ eye movement strategies, while approximately 25% of participants displayed ‘Western’ strategies. Furthermore, the cultural eye movement strategies used by individuals were consistent across recognition and expression tasks. These findings suggest that ‘culture’ alone cannot straightforwardly account for diversity in eye movement patterns. Instead a more complex understanding of how the environment and individual experiences can influence the mechanisms that govern visual processing is required.

    2012-10-01

    Full Text Available Abstract Background Human perception of the odour environment is highly variable. People vary both in their general olfactory acuity as well as in if and how they perceive specific odours. In recent years, it has been shown that genetic differences contribute to variability in both general olfactory acuity and the perception of specific odours. Odour perception also depends on other factors such as age and gender. Here we investigate the influence of these factors on both general olfactory acuity and on the perception of 66 structurally and perceptually different odours in a diverse subject population. Results We carried out a large human olfactory psychophysics study of 391 adult subjects in metropolitan New York City, an ethnically and culturally diverse North American metropolis. 210 of the subjects were women and the median age was 34.6 years (range 19–75. We recorded ~2,300 data points per subject to obtain a comprehensive perceptual phenotype, comprising multiple perceptual measures of 66 diverse odours. We show that general olfactory acuity correlates with gender, age, race, smoking habits, and body type. Young, female, non-smoking subjects had the highest average olfactory acuity. Deviations from normal body type in either direction were associated with decreased olfactory acuity. Beyond these factors we also show that, surprisingly, there are many odour-specific influences of race, age, and gender on olfactory perception. We show over 100 instances in which the intensity or pleasantness perception of an odour is significantly different between two demographic groups. Conclusions These data provide a comprehensive snapshot of the olfactory sense of a diverse population. Olfactory acuity in the population is most strongly influenced by age, followed by gender. We also show a large number of diverse correlations between demographic factors and the perception of individual odours that may reflect genetic differences as well as different

    High immigration rates and relatively high birth rates have made Hispanics the second fastest growing minority population in the US. Only the Asian population is growing faster. In 1996, 11% of the US's population was Hispanic. However, Hispanic Americans are projected to outnumber African Americans by 2005, and by 2050, the Hispanic population in the US is projected to total approximately 100 million, 25% of the US population and the largest of the country's ethnic minorities. Latinos have the lowest rates of high school and college graduation of any major population group in the US. Since relevant data first became available in 1972 and until 1994, the median income of Latino families has remained below that of White families, but above that of African American families. The Hispanics' median family income of $24,000 in 1995 was below that of African American families. Puerto Rican and Mexican families are most likely to be poor, while Cubans are least likely. There is considerable diversity within the US's Hispanic population. For example, some Hispanics speak only Spanish, while others speak no Spanish at all. Hispanic Americans come from many countries and cultures, making the differences between and within the Hispanic ethnic groups sometimes as great as their similarities. Most Americans do not understand that Hispanics are an ethnic group, not a racial group.

    Fostering cultural competence in higher education institutions is essential, particularly in training future health care workers to care for diverse populations. The opportunity to explore techniques to address diversity and cultural competence at a new medical school was undertaken by a multidisciplinary team of librarians, faculty, staff, and medical students. From 2011 to 2015, the team sponsored a voluntary programming series to promote cultural competence and raise awareness of health care disparities for the medical school. Thirteen events were hosted with 562 participants across all. This approach to diversity proved effective and could be adapted in any higher education setting.

    The disparity between the cultural and linguistic diversity of the teaching population and the student population continues to grow as teacher education programs enroll and graduate primarily white teacher candidates (83.7%). At the same time, the diversity of the K-12 student body has increased with 65% of public school students being from culturally and linguistically diverse backgrounds (National Center for Education Statistics, 2007). This chasm between the diversity of the teaching force and student population is of concern as many teachers report that they do not have the cultural knowledge and experience of working or living in diverse environments, yet will be faced with teaching a very diverse student population. Hence, the need for teacher candidates and current teachers to be explicitly taught the skills needed to successfully teach diverse student populations is urgent. In this article, we explore the following phenomena: how linguistic and cultural diversity is regarded in teacher education programs, as well as teacher candidates' and current K-12 teachers' dispositions towards students who do not share their cultural backgrounds or language (including those who vary in their dialects). Finally, we will present strategies that teacher educators can use to embrace and empower culturally and linguistically diverse (CLD) teacher candidates, as well as prepare teacher candidates to teach diverse student populations.

    2012-01-01

    The field of bioethics continues to struggle with the problem of cultural diversity: can universal principles guide ethical decision making, regardless of the culture in which those decisions take place? Or should bioethical principles be derived from the moral traditions of local cultures? Ten Have and Gordijn (2011) and Bracanovic (2011) defend the universalist position, arguing that respect for cultural diversity in matters ethical will lead to a dangerous cultural relativity where vulnerable patients and research subjects will be harmed. We challenge the premises of moral universalism, showing how this approach imports and imposes moral notions of Western society and leads to harm in non-western cultures. PMID:22955969

    Full Text Available The paper focuses on managing cultural diversity at workplaces in Slovenia. The author critically reflects on some aspects of research and studies that have been carried out both on discrimination as well as managing diversity in Slovenia between 2007 and 2013, and finds the cause of the inability of organisations to adopt policies on managing diversity in the lack of competences and skills associated with cultural sensibility. The author maintains that whereas workplaces are bound to become more and more diverse, the predominant approach towards diversity in workplaces in Slovenia tends to either dismiss (cultural diversity as inconsequential or treat it as a nuisance that needs to be dealt with, thus failing to grasp the advantages which such diversity could bring.

    Full Text Available The most important international document relating to the conservation of biodiversity is one adopted by theUN in Rio de Janeiro (1992 that "Convention on Biodiversity". Based on this agreement, the EU has taken a series ofmeasures to reduce genetic erosion in agriculture, which grew with the expansion of industrialized agriculture.Throughout its existence, mankind has used some 10,000 growing plant species. According to FAO statistics, today,90% of food production is ensured by some 120 growing plant species. In addition to drastic reduction in specificdiversity, the advent of industrialized agriculture has generated a process of strong genetic erosion. Old varieties andlocal varieties of crops have mostly been affected, in favour of "modern" varieties. Landraces are characterized by highheterogenity. They have the advantage of being much better adapted to biotic and abiotic stress conditions (diseases,pests, drought, low in nutrients, etc. and have excellent taste qualities, which can justify a higher price recovery thancommercial varieties. Thanks to these features, these crops need small inputs, which correspond to the concept ofsustainable development. Landraces are an invaluable genetic potential for obtaining new varieties of plants and are bestsuited for crop cultivation in ecological systems, becoming more common. Also, for long term food security in thecontext of global warming, rich genetic diversity will be require. “In situ” and “ex situ” conservation are the two majorstrategies used in the conservation of plant genetic resources. There is a fundamental difference between these twostrategies: “ex situ” conservation involves sampling, transfer and storage of a particular species population away fromthe original location, while “in situ” conservation (in their natural habitat implies that the varieties of interest,management and monitoring their place of origin takes place in the community to which they belong.

    Jared Diamond's Guns, Germs, and Steel [Diamond J, (1997) Guns, Germs, and Steel (WW Norton, NY)] has provided a scientific foundation for answering basic questions, such as why Eurasians colonized the global South and not the other way around, and why there is so much variance in economic development across the globe. Diamond's explanatory variables are: (i) the susceptibility of local wild plants to be developed for self-sufficient agriculture; (ii) the domesticability of large wild animals for food, transport, and agricultural production; and (iii) the relative lengths of the axes of continents with implications for the spread of human populations and technologies. This third "continental axis" thesis is the most difficult of Diamond's several explanatory factors to test, given that the number of continents are too few for statistical analysis. This article provides a test of one observable implication of this thesis, namely that linguistic diversity should be more persistent to the degree that a geographic area is oriented more north-south than east-west. Using both modern states and artificial geographic entities as the units of analysis, the results provide significant confirmation of the relationship between geographic orientation and cultural homogenization. Beyond providing empirical support for one observable implication of the continental axis theory, these results have important implications for understanding the roots of cultural diversity, which is an important determinant of economic growth, public goods provision, local violence, and social trust.

    2014-09-01

    A phenomenon that strongly influences the demography of small introduced populations and thereby potentially their genetic diversity is the demographic Allee effect, a reduction in population growth rates at small population sizes. We take a stochastic modeling approach to investigate levels of genetic diversity in populations that successfully overcame either a strong Allee effect, in which populations smaller than a certain critical size are expected to decline, or a weak Allee effect, in which the population growth rate is reduced at small sizes but not negative. Our results indicate that compared to successful populations without an Allee effect, successful populations with a strong Allee effect tend to (1) derive from larger founder population sizes and thus have a higher initial amount of genetic variation, (2) spend fewer generations at small population sizes where genetic drift is particularly strong, and (3) spend more time around the critical population size and thus experience more genetic drift there. In the case of multiple introduction events, there is an additional increase in diversity because Allee-effect populations tend to derive from a larger number of introduction events than other populations. Altogether, a strong Allee effect can either increase or decrease genetic diversity, depending on the average founder population size. By contrast, a weak Allee effect tends to decrease genetic diversity across the entire range of founder population sizes. Finally, we show that it is possible in principle to infer critical population sizes from genetic data, although this would require information from many independently introduced populations.

    As diversity management activities become more prominent worldwide it is important to understand psychological reactions to them to ensure success, but empirical evidence is lacking. This study investigated employees' and managers' intentions and behavior to promote cultural diversity at work in a variety of organizations in the Netherlands, using Ajzen's theory of planned behavior. Predictors of intentions to promote cultural diversity at work (N = 670) and actual behavior after 6 months were assessed among managers and employees using self-reports in a 2-wave survey design. Participants' average age at Time 1 was 38.26 years (SD = 11.86), 56% was female, and there were 78.1% Dutch ethnic majority and 21.9% ethnic minority participants. Attitude to cultural diversity promotion at work and perceived behavioral control (PBC) related positively to both individuals' intentions to promote cultural diversity at work, which in turn predicted behavior. The strongest driver, however, was attitude. Managers' reported PBC and behavior were higher compared to employees. This study supported the applicability of the theory of planned behavior to predict intentions and behavior to promote cultural diversity at work. With an increasingly diverse workforce, this study aimed to advance our understanding of drivers of individual reactions and behavior to support cultural diversity at work.

    This article examines how anti-poverty policy has considered the role of culture and how it ought to do so. While some have explained poverty as a function of the presumed cultural deficiency or distinctiveness of the poor, we suggest that these explanations have not been convincing and that policy requires a broader and more sophisticated understanding of the relationship between culture and behaviour. In fact, we suggest that cultural differences may be positively employed in comprehensive anti-poverty strategies.

    The paper examines the conceptual context of cultural diversity in Sweden. It describes the background in which the former Social Democratic Government declared 2006 as the Year for Cultural Diversity. A related concern is scrutinizing whether in fact this year would be a starting point for more deeply engaged diversity programs or if such policy definitions remain mere symbolic acts of window dressing. The study is based on analysis of official documents, diversity events and agendas, and interviews with different actors and diversity consultants, and participation in seminars and conferences on the topic of diversity and integration as the main topics. A major concern is whether the current interest on cultural diversity may lead to its institutionalization in the Swedish cultural and social organizations (Hamde, 2002a) and address the virtues of diversity, such as diversity for profitability and competence in workplaces, social justice concerns, and finally, societal cohesion. Alternatively, the paper explores if the debate on diversity merely remains a 'traveling' idea to appear occasionally and then occur in fashion-like manner as many management ideas do, leaving little traces on peoples' lives.

  9. Innovativeness, population size and cumulative cultural evolution.

    Henrich [Henrich, J., 2004. Demography and cultural evolution: how adaptive cultural processes can produce maladaptive losses-the Tasmanian case. Am. Antiquity 69, 197-214] proposed a model designed to show that larger population size facilitates cumulative cultural evolution toward higher skill levels. In this model, each newborn attempts to imitate the most highly skilled individual of the parental generation by directly-biased social learning, but the skill level he/she acquires deviates probabilistically from that of the exemplar (cultural parent). The probability that the skill level of the imitator exceeds that of the exemplar can be regarded as the innovation rate. After reformulating Henrich's model rigorously, we introduce an overlapping-generations analog based on the Moran model and derive an approximate formula for the expected change per generation of the highest skill level in the population. For large population size, our overlapping-generations model predicts a much larger effect of population size than Henrich's discrete-generations model. We then investigate by way of Monte Carlo simulations the case where each newborn chooses as his/her exemplar the most highly skilled individual from among a limited number of acquaintances. When the number of acquaintances is small relative to the population size, we find that a change in the innovation rate contributes more than a proportional change in population size to the cumulative cultural evolution of skill level.

    2010-05-01

    Increasing diversity in the classroom challenges nursing educators to identify issues that complicate teaching (perils), analyze barriers for themselves and their students (pitfalls), and select new strategies for working with nontraditional students (pearls). This article identifies concerns arising from attitudes and values within nursing and common approaches to diversity education, and then discusses key issues in nursing education that relate to human nature, culture, faculty workload, and student demographics. Finally, some strategies are proposed for increasing the effectiveness of professional preparation with diverse students through a focus on culturally congruent education and development of faculty cultural competence.

    2011-01-01

    This paper explores the role media play in safeguarding cultural diversity, promoting cultural dialogue, facilitating the exercise of cultural rights,fostering cultural understanding and cultivating intercultural citizenship in the age of globalization. The paper highlights several interconnected leverage points: media content, practices, processes, ownership, education, structures, and policies. It argues that fostering cultural diversity in and through the media can go a long way toward bringing a civic discourse which favors tolerance and facilitates co-existence. It can contribute to the breaking down of cultural barriers, the initiation of cultural dialogues, the empowerment of marginalized groups, and the practice of good governance. At the same time, this paper argues, the celebration of difference does not preclude the valuation of a common cultural core or a common humanity which brings people together in spite of their differences.

    Increasing immigration to Quebec has brought to the surface the need for adapting its public health systems and services, particularly in the area of primary care. The challenge is to take the heterogeneous nature of the population into account and to integrate diverse values, experience and know-how into the development of programmes and delivery of services, whilst simultaneously respecting the values of the various care providers and the norms of the institutions in the host country. This article addresses the question of adaptation strategies for health services, and namely the development of prevention and heath promotion programmes in public health within the framework of primary health care services within the intercultural context of Montreal. The issue of adaptation falls within the perspective and mandate of the Quebec government's policy on health and well-being (La politique de santé et du bien-être, 1992). Furthermore, it is a response to frequent demands from various health professionals and groups concerned with the adaptation of public services with respect to intercultural relationships confronted with the emerging realities associated with immigration. The article provides a reflection on specific ways of adapting prevention and health promotion initiatives targeting cultural communities and those who are undergoing immigration procedures or transitions. It also examines the development of ethno-cultural or other indicators which make it possible to capture migration experiences and their health impact. Since the Quebec health and social services system is currently in the process of major reform, it is hoped that it will seize this opportunity in order to make health and social service centres accountable for the adaptation of their programmes and services to the diversity of the populations they serve.

  16. Extreme genetic diversity in asexual grass thrips populations.

    2016-05-01

    The continuous generation of genetic variation has been proposed as one of the main factors explaining the maintenance of sexual reproduction in nature. However, populations of asexual individuals may attain high levels of genetic diversity through within-lineage diversification, replicate transitions to asexuality from sexual ancestors and migration. How these mechanisms affect genetic variation in populations of closely related sexual and asexual taxa can therefore provide insights into the role of genetic diversity for the maintenance of sexual reproduction. Here, we evaluate patterns of intra- and interpopulation genetic diversity in sexual and asexual populations of Aptinothrips rufus grass thrips. Asexual A. rufus populations are found throughout the world, whereas sexual populations appear to be confined to few locations in the Mediterranean region. We found that asexual A. rufus populations are characterized by extremely high levels of genetic diversity, both in comparison with their sexual relatives and in comparison with other asexual species. Migration is extensive among asexual populations over large geographic distances, whereas close sexual populations are strongly isolated from each other. The combination of extensive migration with replicate evolution of asexual lineages, and a past demographic expansion in at least one of them, generated high local clone diversities in A. rufus. These high clone diversities in asexual populations may mimic certain benefits conferred by sex via genetic diversity and could help explain the extreme success of asexual A. rufus populations.

    Full Text Available The specific aims of this study were to: • Propose a definition of the term cultural diversity; • Validate the term cultural diversity; and • Submit a term and definition for international utilisation to the International Council of Nurses (ICN for consideration for inclusion in the ICNP®. Background South Africa was one of four African countries (Botswana, South Africa. Swaziland, and Zimbabwe funded by the WK Kellogg Foundation to participate in the ICNP® project. South Africa had 2 research groups. One of the research groups identified the term cultural diversity to define. Method This was a qualitative study where a philosophical perspective was used to explore, explain and describe nursing practice. The combined method proposed by the International Council of Nurses (ICN was utilised to define and validate the term cultural diversity. Findings Validation and literature review provided sufficient support for the defined characteristics and the term was finally defined and submitted to ICN in November 2002 as: CULTURAL DIVERSITY is a type of CULTURE with the specific characteristics: co-existence of different groups, e.g. ethnic, religious, linguistic and other groups each with their own values and belief systems, traditions and different lifestyles. Conclusion The research group was informed in December 2003 of the ICNP® Evaluation Committee recommendation that the term cultural diversity will be included in the ICNP®.

    Cultural diversity issues affect the health care workplace and nursing practice. The Lowenstein-Glanville conflict model can be used for assessing and intervening in racial and status conflict in hospital settings. Implications for nursing practice include recognizing that cultural diversity will continue to grow in the health care workplace. Nurses must increase sensitivity, become aware of cultural nuances and issues, and make cultural assessment a routine part of their assessment and planning, not only for patient care, but also with their co-workers and subordinates.

    Culture plays a crucial role in our lives. Depending on our cultural background, we judge on and react to everything that we encounter. Subtle differences in behavior can lead to misunderstandings or even culture shock. In a similar manner, virtual characters can be declined by certain user groups when showing culturally inappropriate behavior. But how can social aspects such as culture be integrated into the behavioral models of virtual characters Birgit Endrass addresses this question by carrying out a hybrid approach that is based on theoretical background from the social sciences as well a

    Speech-language pathologists (SLPs) are working with an increasing number of families from culturally and linguistically diverse backgrounds as the world's population continues to become more internationally mobile. The heterogeneity of these diverse populations makes it impossible to identify and document a one size fits all strategy for working with culturally and linguistically diverse families. This paper explores approaches to practice by SLPs identified as specialising in multilingual and multicultural practice in culturally and linguistically diverse contexts from around the world. Data were obtained from ethnographic observation of 14 sites in 5 countries on 4 continents. The sites included hospital settings, university clinics, school-based settings, private practices and Indigenous community-based services. There were 652 individual artefacts collected from the sites which included interview transcripts, photographs, videos, narrative reflections, informal and formal field notes. The data were analysed using Cultural-Historical Activity Theory (Engeström, 1987). From the analysis six overarching Principles of Culturally Competent Practice (PCCP) were identified. These were: (1) identification of culturally appropriate and mutually motivating therapy goals, (2) knowledge of languages and culture, (3) use of culturally appropriate resources, (4) consideration of the cultural, social and political context, (5) consultation with families and communities, and (6) collaboration between professionals. These overarching principles align with the six position statements developed by the International Expert Panel on Multilingual Children's Speech (2012) which aim to enhance the cultural competence of speech pathologists and their practice. The international examples provided in the current study demonstrate the individualised ways that these overarching principles are enacted in a range of different organisational, social, cultural and political contexts

    2010-06-23

    A principle shared by both economists and ecologists is that a diversified portfolio spreads risk, but this idea has little empirical support in the field of population biology. We found that population growth rates (recruits per spawner) and life-history diversity as measured by variation in freshwater and ocean residency were negatively correlated across short time periods (one to two generations), but positively correlated at longer time periods, in nine Bristol Bay sockeye salmon populations. Further, the relationship between variation in growth rate and life-history diversity was consistently negative. These findings strongly suggest that life-history diversity can both increase production and buffer population fluctuations, particularly over long time periods. Our findings provide new insights into the importance of biocomplexity beyond spatio-temporal aspects of populations, and suggest that maintaining diverse life-history portfolios of populations may be crucial for their resilience to unfavourable conditions like habitat loss and climate change.

    The genetic diversity and genetic variation within and among populations of five natural Davidia involucrata populations were studied from 13 primers based on random amplified polymorphic DNA (RAPD) analysis.The results show that natural D.involucrata population has a rich genetic diversity,and the differences among populations are significant.Twenty-six percent of genetic variation exists among D.involucrata populations,which is similar to that of the endangered tree species Liriodendron chinense and Cathaya argyrophylla in China,but different from more widely distributed tree species.The analysis of the impacts of sampling method on genetic diversity parameters shows that the number of sampled individuals has little effect on the effective number of alleles and genetic diversity,but has a marked effect on the genetic differentiation among populations and gene flows.This study divides the provenances of D.involucrata into two parts,namely,a southeast and a northwest provenance.

  12. A two level mutation-selection model of cultural evolution and diversity.

    Science.gov (United States)

    Salazar-Ciudad, Isaac

    2010-11-21

    Cultural evolution is a complex process that can happen at several levels. At the level of individuals in a population, each human bears a set of cultural traits that he or she can transmit to its offspring (vertical transmission) or to other members of his or her society (horizontal transmission). The relative frequency of a cultural trait in a population or society can thus increase or decrease with the relative reproductive success of its bearers (individual's level) or the relative success of transmission (called the idea's level). This article presents a mathematical model on the interplay between these two levels. The first aim of this article is to explore when cultural evolution is driven by the idea's level, when it is driven by the individual's level and when it is driven by both. These three possibilities are explored in relation to (a) the amount of interchange of cultural traits between individuals, (b) the selective pressure acting on individuals, (c) the rate of production of new cultural traits, (d) the individual's capacity to remember cultural traits and to the population size. The aim is to explore the conditions in which cultural evolution does not lead to a better adaptation of individuals to the environment. This is to contrast the spread of fitness-enhancing ideas, which make individual bearers better adapted to the environment, to the spread of "selfish" ideas, which spread well simply because they are easy to remember but do not help their individual bearers (and may even hurt them). At the same time this article explores in which conditions the adaptation of individuals is maximal. The second aim is to explore how these factors affect cultural diversity, or the amount of different cultural traits in a population. This study suggests that a larger interchange of cultural traits between populations could lead to cultural evolution not improving the adaptation of individuals to their environment and to a decrease of cultural diversity.

    Previous work on mathematical models of cultural evolution has mainly focused on the diffusion of simple cultural elements. However, a characteristic feature of human cultural evolution is the seemingly limitless appearance of new and increasingly complex cultural elements. Here, we develop a general modelling framework to study such cumulative processes, in which we assume that the appearance and disappearance of cultural elements are stochastic events that depend on the current state of culture. Five scenarios are explored: evolution of independent cultural elements, stepwise modification of elements, differentiation or combination of elements and systems of cultural elements. As one application of our framework, we study the evolution of cultural diversity (in time as well as between groups). PMID:21199845

    The field of bioethics continues to struggle with the problem of cultural diversity: can universal principles guide ethical decision making, regardless of the culture in which those decisions take place? Or should bioethical principles be derived from the moral traditions of local cultures? Ten Have and Gordijn (Medicine, Health Care and Philosophy 14:1-3, 2011) and Bracanovic (Medicine, Health Care and Philosophy 14:229-236, 2011) defend the universalist position, arguing that respect for cultural diversity in matters ethical will lead to a dangerous cultural relativity where vulnerable patients and research subjects will be harmed. We challenge the premises of moral universalism, showing how this approach imports and imposes moral notions of Western society and leads to harm in non-western cultures.

  7. Reconstructing marginality: a new model of cultural diversity in nursing.

    Southwick, Margaret; Polaschek, Nick

    2014-05-01

    This article presents a new model of cultural diversity in nursing that critically reconstructs the concept of marginality that underpins other models. Rather than viewing the marginal as "other," marginality is redefined as the space in between the dominant cultural reality and the cultural realities of minority groups located within a society. Members of a minority cultural group who become skilled in the difficult process of negotiating this in-between space open the possibility of transformation within nursing education and practice. This model has been applied in a study of the experience of nursing students of Pacific ethnicity in New Zealand. Subsequently, an undergraduate Pacific nursing program was developed, with greatly increased success rates in registration of Pacific nurses. This model of cultural diversity can also be used to understand nursing practice involving people from minority cultures or other socially excluded categories.

    There are indications that established methods for evaluating information system usability that have been developed for use in, e.g. Europe or the USA, fail to give reliable results in countries such as India, China or Malaysia. This paper presents the theoretical background, related work...... and a definition of culture that should be useful for studies of multiple-country usability testing. This includes a discussion of cultural fit and the consequences of cultural (in)consistencies between stakeholders in system development and use. As an illustrative example of the kind of academic research...... that needs to be done, a pilot study is described. The pilot study exemplifies themes to explore, who should be participants and where should the study be done, how to find examples of multiple-country usability testing, how to collect data and how to analyse that data and what kind of results and discussion...

    Understanding the factors that contribute to loss of genetic diversity in fragmented populations is crucial for conservation measurements. Land-bridge archipelagoes offer ideal model systems for identifying the long-term effects of these factors on genetic variations in wild populations. In this study, we used nine microsatellite markers to quantify genetic diversity and differentiation of 810 pond frogs (Pelophylax nigromaculatus) from 24 islands of the Zhoushan Archipelago and three sites on nearby mainland China and estimated the effects of the island area, population size, time since island isolation, distance to the mainland and distance to the nearest larger island on reduced genetic diversity of insular populations. The mainland populations displayed higher genetic diversity than insular populations. Genetic differentiations and no obvious gene flow were detected among the frog populations on the islands. Hierarchical partitioning analysis showed that only time since island isolation (square-root-transformed) and population size (log-transformed) significantly contributed to insular genetic diversity. These results suggest that decreased genetic diversity and genetic differentiations among insular populations may have been caused by random genetic drift following isolation by rising sea levels during the Holocene. The results provide strong evidence for a relationship between retained genetic diversity and population size and time since island isolation for pond frogs on the islands, consistent with the prediction of the neutral theory for finite populations. Our study highlights the importance of the size and estimated isolation time of populations in understanding the mechanisms of genetic diversity loss and differentiation in fragmented wild populations.

  12. Genetic drift of HIV populations in culture.

    2009-03-01

    Full Text Available Populations of Human Immunodeficiency Virus type 1 (HIV-1 undergo a surprisingly large amount of genetic drift in infected patients despite very large population sizes, which are predicted to be mostly deterministic. Several models have been proposed to explain this phenomenon, but all of them implicitly assume that the process of virus replication itself does not contribute to genetic drift. We developed an assay to measure the amount of genetic drift for HIV populations replicating in cell culture. The assay relies on creation of HIV populations of known size and measurements of variation in frequency of a neutral allele. Using this assay, we show that HIV undergoes approximately ten times more genetic drift than would be expected from its population size, which we defined as the number of infected cells in the culture. We showed that a large portion of the increase in genetic drift is due to non-synchronous infection of target cells. When infections are synchronized, genetic drift for the virus is only 3-fold higher than expected from its population size. Thus, the stochastic nature of biological processes involved in viral replication contributes to increased genetic drift in HIV populations. We propose that appreciation of these effects will allow better understanding of the evolutionary forces acting on HIV in infected patients.

  1. Teaching as a cultural practice: managing diverse classrooms

    Directory of Open Access Journals (Sweden)

    Rosa María RODRÍGUEZ IZQUIERDO

    2011-09-01

    Full Text Available Teaching is a cultural process. Actions that take place in this process are influenced by some cultural assumptions which shape pre-defined objectives and affect content, educational treatment, assessments, and relationships among participants. It is, therefore, of utmost importance not only to make explicit the cultural reality of education, but also to think critically about it. In this paper, we focus on the issue of teaching and learning in the context of cultural diversity from a socio-cultural and socio-political theoretical framework. The keywords «classroom management» it generates over 6.5 million hits in google.com. However, when we type «managing diverse classrooms», there are only 200,000 hits. This divergence indicates that classroom management is a widely explored topic, while work about how to manage a cultural diverse classroom is still limited. The aim of this paper is to provide a framework for teachers to use and improve their cultural knowledge to manage classrooms more effectively. This article argues that growth in cultural awareness of the teaching process improves the quality of teaching and, therefore, students’ learning.

    This special issue of The American Journal on Addictions is an extension of a workshop held at the Research Society on Alcoholism (2015) highlighting several important issues related to studies of the genetic bases of alcohol use disorder among racially/ethnically diverse populations. While not exhaustive in their coverage, the papers in this special issue focus on three important topics: (1) the importance of considering the social and environmental context in genetic analyses; (2) social and cultural considerations for engaging diverse communities in genetic research; and (3) methodologies related to phenotype development for use with racially/ethnically diverse populations. A brief overview of each paper included in these three sections is presented. The issue concludes with additional considerations for genetic research with racially/ethnically diverse population groups along with a commentary.

    Major demographic trends are changing the face of America's labor pool, and healthcare managers increasingly face a scarcer and more diverse workforce. As a result, healthcare organizations (HCOs) must develop policies and practices aimed at recruiting, retaining, and managing a diverse workforce and must meet the demands of a more diverse patient population by providing culturally appropriate care and improving access to care for racial/ethnic minorities. Ultimately, the goal of managing diversity is to enhance workforce and customer satisfaction, to improve communication among members of the workforce, and to further improve organizational performance. Research on diversity management practices in HCOs is scarce, providing few guidelines for practitioners. This study attempted to close that gap. Results show that hospitals in Pennsylvania have been relatively inactive with employing diversity management practices, and equal employment requirements are the main driver of diversity management policy. The number and scope of diversity management practices used were not influenced by organizational or market characteristics. The results suggest that hospitals need to adopt diversity management practices for their workforces and need to pay particular attention to marketing and service planning activities that meet the needs of a diverse patient population.

    This case study examines the current state of cultural competence in hospice and palliative care in the Greater Toronto Area (GTA). Because of changing demographic trends and ethnic minorities underutilizing hospice palliative care services, this research examined the current state of culturally competent care in a hospice setting, and the challenges to providing culturally competent care in a hospice in the GTA. A case study was conducted with a hospice and included in-depth interviews with 14 hospice volunteers. The findings reveal that volunteers encountered cultural clashes when their level of cultural competency was weak. Second, volunteers revealed there was a lack of adequate cultural competency training with their hospice, and finally, there was a lack of ethnic, cultural, and linguistic diversity among the hospice volunteers.

    The movement to respect cultural diversity, known as multiculturalism, poses a daunting challenge to healthcare ethics. Can we construct a defensible passage from the fact of cultural differences to any claims regarding morality? Or does multiculturalism lead to ethical relativism? Macklin argues that, in view of a leading distinction between universalism in ethics and moral absolutism, the only reasonable passage avoids both absolutism and relativism. She presents a strong case against ethical relativism and its pernicious consequences for cross-cultural issues in healthcare. She also provides sound criteria for the assessment of a culture's moral progress.

    The population sizes of three Korean indigenous cattle populations have been drastically reduced over the past decades. In this study, we examined the extent to which reduction in populations influenced genetic diversity, population structure and demographic history using complete mitochondrial DNA (mtDNA) control region sequences. The complete mtDNA control region was sequenced in 56 individuals from Korean Black (KB), Jeju Black (JEB) and Korean Brindle (BRI) cattle populations. We included 27 mtDNA sequences of Korean Brown (BRO) from the GenBank database. Haplotype diversity estimate for the total population was high (0.870) while nucleotide diversity was low (0.004). The KB showed considerably low nucleotide (π = 0.001) and haplotype (h = 0.368) diversities. Analysis of molecular variance revealed a low level of genetic differentiation but this was highly significant (ppopulations. Of the total genetic diversity, 7.6% was attributable to among cattle populations diversity and the rest (92.4%) to differences within populations. The mismatch distribution analysis and neutrality tests revealed that KB population was in genetic equilibrium or decline. Indeed, unless an appropriate breeding management practice is developed, inbreeding and genetic drift will further impoverish genetic diversity of these cattle populations. Rational breed development and conservation strategy is needed to safeguard these cattle population.

    Background Helichrysum italicum (Asteraceae) is a small shrub endemic to the Mediterranean Basin, growing in fragmented and diverse habitats. The species has attracted attention due to its secondary metabolite content, but little effort has as yet been dedicated to assessing the genetic and metabolite diversity present in these populations. Here, we describe the diversity of 50 H. italicum populations collected from a range of habitats in Sardinia. Methods H. italicum plants were AFLP fingerprinted and the composition of their leaf essential oil characterized by GC-MS. The relationships between the genetic structure of the populations, soil, habitat and climatic variables and the essential oil chemotypes present were evaluated using Bayesian clustering, contingency analyses and AMOVA. Key results The Sardinian germplasm could be partitioned into two AFLP-based clades. Populations collected from the southwestern region constituted a homogeneous group which remained virtually intact even at high levels of K. The second, much larger clade was more diverse. A positive correlation between genetic diversity and elevation suggested the action of natural purifying selection. Four main classes of compounds were identified among the essential oils, namely monoterpenes, oxygenated monoterpenes, sesquiterpenes and oxygenated sesquiterpenes. Oxygenated monoterpene levels were significantly correlated with the AFLP-based clade structure, suggesting a correspondence between gene pool and chemical diversity. Conclusions The results suggest an association between chemotype, genetic diversity and collection location which is relevant for the planning of future collections aimed at identifying valuable sources of essential oil.

    Full Text Available AIMS: We investigate native and introduced populations of Solanum rostratum, an annual, self-compatible plant that has been introduced around the globe. This study is the first to compare the genetic diversity of Solanum rostratum between native and introduced populations. We aim to (1 determine the level of genetic diversity across the studied regions; (2 explore the likely origins of invasive populations in China; and (3 investigate whether there is the evidence of multiple introductions into China. METHODS: We genotyped 329 individuals at 10 microsatellite loci to determine the levels of genetic diversity and to investigate population structure of native and introduced populations of S. rostratum. We studied five populations in each of three regions across two continents: Mexico, the U.S.A. and China. IMPORTANT FINDINGS: We found the highest genetic diversity among Mexican populations of S. rostratum. Genetic diversity was significantly lower in Chinese and U.S.A. populations, but we found no regional difference in inbreeding coefficients (F IS or population differentiation (F ST. Population structure analyses indicate that Chinese and U.S.A. populations are more closely related to each other than to sampled Mexican populations, revealing that introduced populations in China share an origin with the sampled U.S.A. populations. The distinctiveness between some introduced populations indicates multiple introductions of S. rostratum into China.

    Full Text Available The Greater Toronto Area (GTA is one of the most multicultural communities in the world. Frequently, this description is based on ethnic, linguistic, and culinary diversity. Physical cultural diversity, such as different sports, martial arts, forms of dance, exercise systems, and other physical games and activities, remains ignored and understudied. Based on a living database of the GTA’s physical cultural diversity, this study identifies the trajectories of the lifecycle of activities that have been introduced into the GTA’s physical culture by immigrants. These pathways differ based on whether the activity is offered in a separate setting, where individuals may be participating with other immigrants of the same ethnocultural group, or mixed settings, where people are participating with people from outside of their ethnocultural group. We argue that the diversity and the lifecycle trajectories of physical cultural forms in the GTA serve as evidence of interculturalism and the contribution by immigrants to the social and cultural life of Canada.

    There are inequalities in health among migrants and local populations in Europe. Due to migration, Germany, Norway and Sweden have become ethnic culturally diverse nations. There are barriers to mental health care access for refugees, migrants and minorities, and problems with quality of culturally sensitive care in the three countries. This is despite tax-funded health care systems based on equity in service provision. There is a need to develop culturally sensitive mental health services that respond to the increasing diversity of the populations. In this chapter, we will take a closer look at cultural diversity in the countries in question, discuss challenges and give examples of current work to open up mental health services to cultural diversity. The German example will focus on the movement of Interkulturelle Öffnung (cross-cultural opening of the health care system) and work on creating national guidelines and quality standards. From Norway, the work of the National Centre for Mental Health for the indigenous Sámi population will be presented. The Swedish example will focus on the work carried out by the Transcultural Centre. The latter is a competence centre supporting development of culturally sensitive care as an integrated part of the regional health and mental health care system in Stockholm. Finally, the relevance of mental health care for a culturally diverse population, as a part of the larger social project of building tolerant multicultural societies, will be discussed.

    Full Text Available Tetrodotoxin (TTX is a neurotoxin that has been reported from taxonomically diverse organisms across 14 different phyla. The biogenic origin of tetrodotoxin is still disputed, however, TTX biosynthesis by host-associated bacteria has been reported. An investigation into the culturable microbial populations from the TTX-associated blue-ringed octopus Hapalochlaena sp. and sea slug Pleurobranchaea maculata revealed a surprisingly high microbial diversity. Although TTX was not detected among the cultured isolates, PCR screening identifiedsome natural product biosynthesis genes putatively involved in its assembly. This study is the first to report on the microbial diversity of culturable communities from H. maculosa and P. maculata and common natural product biosynthesis genes from their microbiota. We also reassess the production of TTX reported from three bacterial strains isolated from the TTX-containing gastropod Nassarius semiplicatus.

    2012-09-01

    Full Text Available The emerging fields of microbial population genetics and genomics provide an avenue to study the ecological rules that govern how communities form, function, and evolve. Our struggle to understand the causes and consequences of microbial diversity stems from our inability to define ecologically and evolutionarily meaningful units of diversity. The 16S rRNA-based tools that have been so useful in charting microbial diversity may lack sufficient sensitivity to answer many questions about the ecology and evolution of microbes. Examining genetic diversity with increased resolution is vital to understanding the forces shaping community structure. Population genetic analyses enabled by whole genome sequencing, multilocus sequence analyses, or single nucleotide polymorphism analyses permit the testing of hypotheses pertaining to the geographic distribution, migration, and habitat preference of specific microbial lineages. Furthermore, these approaches can reveal patterns of gene exchange within and between populations and communities. Tools from microbial population genetics and population genomics can be used to increase the resolution with which we measure microbial diversity, enabling a focus on the scale of genetic diversity at which

    One of the most pervasive themes in ecology is that biological diversity stabilizes ecosystem processes and the services they provide to society, a concept that has become a common argument for biodiversity conservation. Species-rich communities are thought to produce more temporally stable ecosystem services because of the complementary or independent dynamics among species that perform similar ecosystem functions. Such variance dampening within communities is referred to as a portfolio effect and is analogous to the effects of asset diversity on the stability of financial portfolios. In ecology, these arguments have focused on the effects of species diversity on ecosystem stability but have not considered the importance of biologically relevant diversity within individual species. Current rates of population extirpation are probably at least three orders of magnitude higher than species extinction rates, so there is a pressing need to clarify how population and life history diversity affect the performance of individual species in providing important ecosystem services. Here we use five decades of data from Oncorhynchus nerka (sockeye salmon) in Bristol Bay, Alaska, to provide the first quantification of portfolio effects that derive from population and life history diversity in an important and heavily exploited species. Variability in annual Bristol Bay salmon returns is 2.2 times lower than it would be if the system consisted of a single homogenous population rather than the several hundred discrete populations it currently consists of. Furthermore, if it were a single homogeneous population, such increased variability would lead to ten times more frequent fisheries closures. Portfolio effects are also evident in watershed food webs, where they stabilize and extend predator access to salmon resources. Our results demonstrate the critical importance of maintaining population diversity for stabilizing ecosystem services and securing the economies and livelihoods

    Full Text Available A case of chronic osteomyelitis probably caused by Morganella morganii, occurring over a period of 30 years, is reported. The organism was identified through a combination of sample culture, direct sequencing, and 16S RNA gene amplicon sequencing. Further whole-genome sequencing and population structure analysis of the isolates from the patient showed the bacterial population to be highly diverse. This case provides a valuable example of a long-term infection caused by an opportunistic pathogen, M. morganii, with high diversity, which might evolve during replication within the host.

    A case of chronic osteomyelitis probably caused by Morganella morganii, occurring over a period of 30 years, is reported. The organism was identified through a combination of sample culture, direct sequencing, and 16S RNA gene amplicon sequencing. Further whole-genome sequencing and population structure analysis of the isolates from the patient showed the bacterial population to be highly diverse. This case provides a valuable example of a long-term infection caused by an opportunistic pathogen, M. morganii, with high diversity, which might evolve during replication within the host.

  4. Cultural diversity, democracy and the prospects of cosmopolitanism: a theory of cultural encounters.

    2011-12-01

    The most appropriate way of theorizing cultural diversity is to situate it in the context of a broader relational theory of culture in which the key dynamic is cultural encounters. The relational conception of culture places the emphasis on the relations between social actors and the processes by which some of these relations generate enduring cultural regularities and forms. This has important implications for political community and in particular for cosmopolitanism. It is in relationships that cultural phenomena are generated and become the basis of different kinds of political community. The paper outlines a typology of six kinds of cultural encounters and discusses four major cultural trends that variously emerge from these encounters. This approach with its emphasis on cultural encounters is the broad sociological context in which questions about cultural change and the prospects of cosmopolitanism should be discussed.

    2011-06-01

    Full Text Available There is no universally accepted definition for the concept of culture. Culture should be understood as a specific and unique phenomenon that affirms community’s identity and diversity. Judging one culture by the values of another, over-simplifies the distinctiveness and the wealth of a particular culture. Recognising, understanding and respecting dynamics of cultural norms, and defending and expanding cultural freedom are crucial in assuring secure and sustainable well-being of any community. This paper investigates different perspectives of culture by referring to everyday livelihood activities of rural communities that engage in traditional craft industries in the Kandyan region, Sri Lanka. In a livelihood perspective, culture is defined as a structure, function, product and identity, through its influence on everyday lives of people, and accordingly people’s engagement with and uses of culture. Culture is multifaceted and extremely diverse entity that varies from place to place and person to person. The strengths of cultural diversity should be respected and accepted by mainstream society, if any initiative is to be truly about satisfying human desires.

    Full Text Available Irwin B Horwitz1, Marilyn Sonilal2, Sujin K Horwitz31Cameron School of Business, University of St. Thomas, Houston, TX, USA; 2School of Public Health, University of Texas, Houston, TX, USAAbstract: The growing diversity of the population has resulted in substantial challenges for the US health care system. A substantial body of evidence has identified significant disparities in health care among culturally and ethnically diverse patients, irrespective of income, that negatively affects such factors as diagnostic precision, quality of care, adherence to healing protocols, and overall treatment outcomes. Diversity has also been shown to compromise the functionality of health care teams that are increasingly comprised of members with culturally different backgrounds, in which diversity produces misunderstanding and conflict. Many of the problems stem from a lack of cultural competence among both physicians and teams under their supervision. To reduce the numerous problems resulting from inadequate cultural competence among health care professionals, this article examines ways in which the issues of diversity can be effectively addressed in health care institutions. It is advocated that physicians adopt a proactive transformational leadership style to manage diversity because of its emphasis on understanding and aligning follower values which lie at the heart of diversity-related misunderstandings. It is also held that for leadership training among physicians to be fully effective, it should be integrated with organizational-wide diversity programs. By doing so, the complimentary effect could result in comprehensive change, resulting in substantial improvements in the quality of health care for all patients.Keywords: leadership, diversity, health care, disparities, medical education

  17. Diverse Populations in Saskatchewan: The Challenges of Reaching Them

    Full Text Available Saskatchewan is more diverse than it was even 5 years ago. Although historically Saskatchewan has always had a diverse immigrant population with new immigrants coming from many European and Eastern European countries, recently there are large immigrant communities arriving: some as refugees, some as guest workers, international students and their families from several parts of the globe through various significant government initiatives and policies. Not only is this diverse immigrant population growing, but the social make up of the new immigrants is also changing. There are many reasons why Saskatchewan is receiving more immigrants. This paper states those reasons, discusses the history of immigration in Saskatchewan, current immigrant situation, and the role libraries can play in educating, informing and entertaining these immigrant populations. This paper focuses on new immigrants coming into Saskatchewan and does not discuss other groups that are part of a diverse society such as aboriginal populations, seniors, the GBLT, or French Canadians. The authors sent out questionnaires to see what other libraries in Canada have done in this area and have looked into Vancouver Public Library and Toronto Public Library as examples for programs and services that can be offered to diverse immigrant populations.

    2007-12-01

    This article offers practical strategies to managers and others for supporting overseas trained nurses and managing cultural diversity in the health workforce. Widespread nursing shortages have led managers to recruit nurses from overseas, mainly from developing countries. This paper draws on evidence from the Researching Equal Opportunities for Internationally Recruited Nurses and Other Health Professionals study reported elsewhere in this issue, which indicates that overseas trained nurses encountered widespread discriminatory practices including an overuse of complaints and grievances against them. The researchers also found that the overseas trained nurses responded to their experiences by using various personal strategies to resist or re-negotiate and overcome such discriminatory practices. A research workshop was held in June 2005 at the midpoint of the Researching Equal Opportunities for Internationally Recruited Nurses and Other Health Professionals study. Twenty-five participants attended the workshop. They were the Researching Equal Opportunities for Internationally Recruited Nurses and Other Health Professionals study researchers, advisory group members, including the author of this paper and other researchers in the field of migration. The overall aim of the workshop was to share emerging research data from the Researching Equal Opportunities for Internationally Recruited Nurses and Other Health Professionals and related studies. The final session of the workshop on which this paper is based, was facilitated by the author, with the specific aim of asking the participants to discuss and determine the challenges to managers when managing a culturally diverse workforce. The discussion yielded four main themes collated by the author from which a framework of strategies to facilitate equality and cultural diversity management of the healthcare workers may be developed. The four themes are: assumptions and expectations; education and training to include

    Using data from population-based samples of adults participating in the ICS-II USA study, and using principal components analysis, we constructed oral health belief measures corresponding to the Health Belief Model (HBM) dimensions. Tests of validity and reliability were performed. Scales measuring perceived benefit of preventive practices and seriousness of oral disease had the highest validity and reliability. We used multiple regression analysis to examine sociodemographic predictors of perceived benefits of preventive practices. Race-ethnicity and age cohort were significant predictors among Baltimore and San Antonio adults. White adults and middle-aged persons in both research locations were more likely to believe in the benefit of preventive practices. Female gender, higher educational attainment, and better self-rated health were significant indicators of more positive oral health beliefs in every research location. Results also characterize persons who place lower value on preventive practices (i.e., males, less-educated persons, and those reporting poorer self-rated health). The design of effective dental public health messages and outreach efforts requires an analysis of the individual's health orientation and the factors influencing oral health beliefs. Oral health education interventions designed to improve health beliefs should contain an evaluation component for assessing the impact of education on health practices and oral health status.

    The effect of altitude and season on abundance and diversity of the culturable heterotrophic bacterial and yeast community was examined at four forest sites in the Italian Alps along an altitude gradient (545-2000 m). Independently of altitude, bacteria isolated at 0 °C (psychrophiles) were less numerous than those recovered at 20 °C. In autumn, psychrophilic bacterial population increased with altitude. The 1194 bacterial strains were primarily affiliated with the classes Alpha-, Beta-, Gammaproteobacteria, Spingobacteriia and Flavobacteriia. Fifty-seven of 112 operational taxonomic units represented potential novel species. Strains isolated at 20 °C had a higher diversity and showed similarities in taxa composition and abundance, regardless of altitude or season, while strains isolated at 0 °C showed differences in community composition at lower and higher altitudes. In contrast to bacteria, yeast diversity was season-dependent: site- and altitude-specific effects on yeast diversity were only detected in spring. Isolation temperature affected the relative proportions of yeast genera. Isolations recovered 719 strains, belonging to the classes Dothideomycetes, Saccharomycetes, Tremellomycetes and Mycrobotryomycetes. The presence of few dominant bacterial OTUs and yeast species indicated a resilient microbial population that is not affected by season or altitude. Soil nutrient contents influenced significantly abundance and diversity of culturable bacteria, but not of culturable yeasts.

    The Arabian horse ignites imagination throughout the world. Populations of this breed exist in many countries, and recent genetic work has examined the diversity and ancestry of a few of these populations in isolation. Here, we explore 7 different populations of Arabians represented by 682 horses. Three of these are Middle Eastern populations from near the historical origin of the breed, including Syrian, Persian, and Saudi Arabian. The remaining Western populations are found in Europe (the Shagya Arabian and Polish Arabian) and in America (American Arabian). Analysis of genetic structure was carried out using 15 microsatellite loci. Genetic distances, analysis of molecular variance, factorial correspondence analysis, and a Bayesian method were applied. The results consistently show higher level of diversity within the Middle Eastern populations than the Western populations. The Western Arabian populations were the main source among population variation. Genetic differentiation was not strong among all Middle Eastern populations, but all American Arabians showed differentiation from Middle Eastern populations and were somewhat uniform among themselves. Here, we explore the diversities of many different populations of Arabian horses and find that populations not from the Middle East have noticeably lower levels of diversity, which may adversely affect the health of these populations.

  2. CRISPR associated diversity within a population of Sulfolobus islandicus.

    Directory of Open Access Journals (Sweden)

    Nicole L Held

    Full Text Available BACKGROUND: Predator-prey models for virus-host interactions predict that viruses will cause oscillations of microbial host densities due to an arms race between resistance and virulence. A new form of microbial resistance, CRISPRs (clustered regularly interspaced short palindromic repeats are a rapidly evolving, sequence-specific immunity mechanism in which a short piece of invading viral DNA is inserted into the host's chromosome, thereby rendering the host resistant to further infection. Few studies have linked this form of resistance to population dynamics in natural microbial populations. METHODOLOGY/PRINCIPAL FINDINGS: We examined sequence diversity in 39 strains of the archeaon Sulfolobus islandicus from a single, isolated hot spring from Kamchatka, Russia to determine the effects of CRISPR immunity on microbial population dynamics. First, multiple housekeeping genetic markers identify a large clonal group of identical genotypes coexisting with a diverse set of rare genotypes. Second, the sequence-specific CRISPR spacer arrays split the large group of isolates into two very different groups and reveal extensive diversity and no evidence for dominance of a single clone within the population. CONCLUSIONS/SIGNIFICANCE: The evenness of resistance genotypes found within this population of S. islandicus is indicative of a lack of strain dominance, in contrast to the prediction for a resistant strain in a simple predator-prey interaction. Based on evidence for the independent acquisition of resistant sequences, we hypothesize that CRISPR mediated clonal interference between resistant strains promotes and maintains diversity in this natural population.

    Full Text Available Large-scale sequencing efforts have documented extensive genetic variation within the human genome. However, our understanding of the origins, global distribution, and functional consequences of this variation is far from complete. While regulatory variation influencing gene expression has been studied within a handful of populations, the breadth of transcriptome differences across diverse human populations has not been systematically analyzed. To better understand the spectrum of gene expression variation, alternative splicing, and the population genetics of regulatory variation in humans, we have sequenced the genomes, exomes, and transcriptomes of EBV transformed lymphoblastoid cell lines derived from 45 individuals in the Human Genome Diversity Panel (HGDP. The populations sampled span the geographic breadth of human migration history and include Namibian San, Mbuti Pygmies of the Democratic Republic of Congo, Algerian Mozabites, Pathan of Pakistan, Cambodians of East Asia, Yakut of Siberia, and Mayans of Mexico. We discover that approximately 25.0% of the variation in gene expression found amongst individuals can be attributed to population differences. However, we find few genes that are systematically differentially expressed among populations. Of this population-specific variation, 75.5% is due to expression rather than splicing variability, and we find few genes with strong evidence for differential splicing across populations. Allelic expression analyses indicate that previously mapped common regulatory variants identified in eight populations from the International Haplotype Map Phase 3 project have similar effects in our seven sampled HGDP populations, suggesting that the cellular effects of common variants are shared across diverse populations. Together, these results provide a resource for studies analyzing functional differences across populations by estimating the degree of shared gene expression, alternative splicing, and

    This study describes the genetic diversity and population structure of 194 native maize populations from 23 countries of Latin America and the Caribbean. The germplasm, representing 131 distinct landraces, was genetically characterized as population bulks using 28 SSR markers. Three main groups of maize germplasm were identified. The first, the Mexico and Southern Andes group, highlights the Pre-Columbian and modern exchange of germplasm between North and South America. The second group, Mesoamerica lowland, supports the hypothesis that two separate human migration events could have contributed to Caribbean maize germplasm. The third, the Andean group, displayed early introduction of maize into the Andes, with little mixing since then, other than a regional interchange zone active in the past. Events and activities in the pre- and post-Columbian Americas including the development and expansion of pre-Columbian cultures and the arrival of Europeans to the Americas are discussed in relation to the history of maize migration from its point of domestication in Mesoamerica to South America and the Caribbean through sea and land routes.

    In this study, we compare the level and distribution of genetic variation between South African conserved and village chicken populations using microsatellite markers. In addition, diversity in South African chickens was compared to that of a reference data set consisting of other African and purebred commercial lines. Three chicken populations Venda, Ovambo and Eastern Cape and four conserved flocks of the Venda, Ovambo, Naked Neck and Potchefstroom Koekoek from the Poultry Breeding Resource Unit of the Agricultural Research Council were genotyped at 29 autosomal microsatellite loci. All markers were polymorphic. Village chicken populations were more diverse than conservation flocks. structure software was used to cluster individuals to a predefined number of 2 ≤ K ≤ 6 clusters. The most probable clustering was found at K = 5 (95% identical runs). At this level of differentiation, the four conservation flocks separated as four independent clusters, while the three village chicken populations together formed another cluster. Thus, cluster analysis indicated a clear subdivision of each of the conservation flocks that were different from the three village chicken populations. The contribution of each South African chicken populations to the total diversity of the chickens studied was determined by calculating the optimal core set contributions based on Marker estimated kinship. Safe set analysis was carried out using bootstrapped kinship values calculated to relate the added genetic diversity of seven South African chicken populations to a set of reference populations consisting of other African and purebred commercial broiler and layer chickens. In both core set and the safe set analyses, village chicken populations scored slightly higher to the reference set compared to conservation flocks. Overall, the present study demonstrated that the conservation flocks of South African chickens displayed considerable genetic variability that is different from that of the

    We hypothesized that diversion of the first milliliter of venipuncture blood-the initial specimen diversion technique (ISDT)-would eliminate incompletely sterilized fragments of skin from the culture specimen and significantly reduce our blood culture contamination rate (R). We studied our hypothesis prospectively beginning with our control culture (C) definition: one venipuncture with two sequentially obtained specimens, 10 ml each, the first specimen (M1) for aerobic and the second (M2) for anaerobic media. The test ISDT culture (D) was identical, with the exception that each was preceded by diverting a 1-ml sample (DS) from the same venipuncture. During the first of two sequential 9-month periods, we captured D versus C data (n=3,733), where DMXR and CMXR are R for D and C specimens. Our hypothesis predicted DS would divert soiled skin fragments from DM1, and therefore, CM1R would be significantly greater than DM1R. This was confirmed by CM1R (30/1,061 [2.8%]) less DM1R (37/2,672 [1.4%]; P=0.005), which equals 1.4%. For the second 9-month follow-up period, data were compiled for all cultures (n=4,143), where ADMXR is R for all (A) diversion specimens, enabling comparison to test ISDT. Our hypothesis predicted no significant differences for test ISDT versus all ISDT. This was confirmed by DM1R (37/2,672 [1.4%]) versus ADM1R (42/4,143 [1.0%]; P=0.17) and DM2R (21/2,672 [0.80%]) versus ADM2R (39/4,143 [0.94%]; P=0.50). We conclude that our hypothesis is valid: venipuncture needles soil blood culture specimens with unsterilized skin fragments and increase R, and ISDT significantly reduces R from venipuncture-obtained blood culture specimens.

    Hepatacodium miconioides is the Class Ⅱ protected plant species in China.This paper studies the genetic diversity and differentiation of its nine natural populations in Zhejiang Province by using random amplified polymorphic DNA (RAPD) technique.Twelve random primers were selected in the amplification,and 164 repetitive loci were produced.The percentage of polymorphic loci in each H.miconioides population ranged from 14.60% to 27.44%,with an average of 20.73%.Among the test populations,Kuochangshan had the highest percentage of polymorphic loci,Simingshan took the second place,and Guanyinping had the lowest percentage.As estimated by Shannon index,the genetic diversity within H.miconioides populations accounted for 27.28% of the total genetic diversity,while that among H.miconioides populations accounted for 72.72%.The genetic differentiation among H.miconioides populations as estimated by Nei index was 0.715,7.This figure was generally consistent with that estimated by Shannon index,i.e.,the genetic differentiation among populations was relatively high,but that within populations was relatively low.The gene flow among H.miconioides populations was relatively low (0.198,7),and the genetic similarity ranged from 0.655,7 to 0.811,9,with an average of 0.730,6.The highest genetic distance among populations was 0.422,9,while the lowest was 0.208,3.All the results showed that there was a distinct genetic differentiation among H.miconioides populations.The genetic distance matrix of nine test populations was calculated using this method,and the clustering analysis was made using the unweighted pair group method with arithmetic mean (UPGMA).The cluster analysis suggested that the ninepopulations of H.miconioides in Zhejiang Province could be divided into two groups,the eastern Zhejiang group and the western Zhejiang group.

    Sense of community (SOC) is one of the most widely used and studied constructs in community psychology. As proposed by Sarason in (The Psychological sense of community: prospects for a community psychology, Jossey-Bass, San Francisco, 1974), SOC represents the strength of bonding among community members. It is a valuable component of community life, and it has been linked to positive mental health outcomes, citizen participation, and community connectedness. However, promotion of SOC can become problematic in community psychology praxis when it conflicts with other core values proposed to define the field, namely values of human diversity, cultural relativity, and heterogeneity of experience and perspective. Several commentators have noted that promotion of SOC can conflict with multicultural diversity because it tends to emphasize group member similarity and appears to be higher in homogeneous communities. In this paper, we introduce the idea of a community-diversity dialectic as part of praxis and research in community psychology. We argue that systematic consideration of cultural psychology perspectives can guide efforts to address a community-diversity dialectic and revise SOC formulations that ultimately will invigorate community research and action. We provide a working agenda for addressing this dialectic, proposing that systematic consideration of the creative tension between SOC and diversity can be beneficial to community psychology.

    Full Text Available Abstract Background Extensive genetic diversity in viral populations within infected hosts and the divergence of variants from existing reference genomes impede the analysis of deep viral sequencing data. A de novo population consensus assembly is valuable both as a single linear representation of the population and as a backbone on which intra-host variants can be accurately mapped. The availability of consensus assemblies and robustly mapped variants are crucial to the genetic study of viral disease progression, transmission dynamics, and viral evolution. Existing de novo assembly techniques fail to robustly assemble ultra-deep sequence data from genetically heterogeneous populations such as viruses into full-length genomes due to the presence of extensive genetic variability, contaminants, and variable sequence coverage. Results We present VICUNA, a de novo assembly algorithm suitable for generating consensus assemblies from genetically heterogeneous populations. We demonstrate its effectiveness on Dengue, Human Immunodeficiency and West Nile viral populations, representing a range of intra-host diversity. Compared to state-of-the-art assemblers designed for haploid or diploid systems, VICUNA recovers full-length consensus and captures insertion/deletion polymorphisms in diverse samples. Final assemblies maintain a high base calling accuracy. VICUNA program is publicly available at: http://www.broadinstitute.org/scientific-community/science/projects/viral-genomics/ viral-genomics-analysis-software. Conclusions We developed VICUNA, a publicly available software tool, that enables consensus assembly of ultra-deep sequence derived from diverse viral populations. While VICUNA was developed for the analysis of viral populations, its application to other heterogeneous sequence data sets such as metagenomic or tumor cell population samples may prove beneficial in these fields of research.

    The genetic diversities of 16 Paulownia fortunei populations involving 143 individuals collected from 6 provinces in China were analyzed using amplified fragment length polymorphism (AFLP). A total of 9 primer pairs with 1169 polymorphic loci were screened out, and each pair possessed 132 bands on average. The percentage of polymorphic bands (98.57%), the effective number of alleles (1.2138-1.2726), Nei's genetic diversity (0.1566-0.1887), and Shannon's information index (0.2692-0.3117) indicated a plentiful genetic diversity and different among Paulownia fortunei populations. The genetic differentiation coefficient between populations was 0.2386, while the gene flow was 1.0954, and the low gene exchange promoted genetic differentiation. Analysis of variance indicated that genetic variation mainly occurred within populations (81.62% of total variation) rather than among populations (18.38%). The 16 populations were divided by unweighted pair-group method with arithmetic means (UPGMA) into 4 groups with obvious regionalism, in which the populations with close geographical locations (latitude) were clustered together.

    The compositional stability of the complex Gouda cheese starter culture Ur is thought to be influenced by diversity in phage resistance of highly related strains that co-exist together with bacteriophages. To analyze the role of bacteriophages in maintaining culture diversity at the level of genetic lineages, simple blends of Lactococcus lactis strains were made and subsequently propagated for 152 generations in the absence and presence of selected bacteriophages. We first screened 102 single-colony isolates (strains) from the complex cheese starter for resistance to bacteriophages isolated from this starter. The collection of isolates represents all lactococcal genetic lineages present in the culture. Large differences were found in bacteriophage resistance among strains belonging to the same genetic lineage and among strains from different lineages. The blends of strains were designed such that 3 genetic lineages were represented by strains with different levels of phage resistance. The relative abundance of the lineages in blends with phages was not stable throughout propagation, leading to continuous changes in composition up to 152 generations. The individual resistance of strains to phage predation was confirmed as one of the factors influencing starter culture diversity. Furthermore, loss of proteolytic activity of initially proteolytic strains was found. Reconstituted blends with only 4 strains with a variable degree of phage resistance showed complex behavior during prolonged propagation. Copyright © 2015 American Dairy Science Association.

    2011-02-12

    A growing body of theoretical and empirical research has examined cultural transmission and adaptive cultural behaviour at the individual, within-group level. However, relatively few studies have tried to examine proximate transmission or test ultimate adaptive hypotheses about behavioural or cultural diversity at a between-societies macro-level. In both the history of anthropology and in present-day work, a common approach to examining adaptive behaviour at the macro-level has been through correlating various cultural traits with features of ecology. We discuss some difficulties with simple ecological associations, and then review cultural phylogenetic studies that have attempted to go beyond correlations to understand the underlying cultural evolutionary processes. We conclude with an example of a phylogenetically controlled approach to understanding proximate transmission pathways in Austronesian cultural diversity.

    Despite the importance attributed to the effects of diversity on the stability and prosperity of nations, the origins of the uneven distribution of ethnic and cultural fragmentation across countries have been underexplored. Building on the role of deeply-rooted biogeographical forces in comparative development, this research empirically demonstrates that genetic diversity, predominantly determined during the prehistoric “out of Africa” migration of humans, is an underlying cause of various existing manifestations of ethnolinguistic heterogeneity. Further exploration of this uncharted territory may revolutionize the understanding of the effects of deeply-rooted factors on economic development and the composition of human capital across the globe.

    Full Text Available Plasmodium vivax is the geographically most widespread human malaria parasite. To analyze patterns of microsatellite diversity and population structure across countries of different transmission intensity, genotyping data from 11 microsatellite markers was either generated or compiled from 841 isolates from four continents collected in 1999-2008. Diversity was highest in South-East Asia (mean allelic richness 10.0-12.8, intermediate in the South Pacific (8.1-9.9 Madagascar and Sudan (7.9-8.4, and lowest in South America and Central Asia (5.5-7.2. A reduced panel of only 3 markers was sufficient to identify approx. 90% of all haplotypes in South Pacific, African and SE-Asian populations, but only 60-80% in Latin American populations, suggesting that typing of 2-6 markers, depending on the level of endemicity, is sufficient for epidemiological studies. Clustering analysis showed distinct clusters in Peru and Brazil, but little sub-structuring was observed within Africa, SE-Asia or the South Pacific. Isolates from Uzbekistan were exceptional, as a near-clonal parasite population was observed that was clearly separated from all other populations (FST>0.2. Outside Central Asia FST values were highest (0.11-0.16 between South American and all other populations, and lowest (0.04-0.07 between populations from South-East Asia and the South Pacific. These comparisons between P. vivax populations from four continents indicated that not only transmission intensity, but also geographical isolation affect diversity and population structure. However, the high effective population size results in slow changes of these parameters. This persistency must be taken into account when assessing the impact of control programs on the genetic structure of parasite populations.

    Full Text Available Genetic diversity within species may promote resilience to environmental change, yet little is known about how such variation is distributed at broad geographic scales. Here we develop a novel Bayesian methodology to analyse multi-species genetic diversity data in order to identify regions of high or low genetic diversity. We apply this method to co-distributed taxa from Australian marine waters. We extracted published summary statistics of population genetic diversity from 118 studies of 101 species and > 1000 populations from the Australian marine economic zone. We analysed these data using two approaches: a linear mixed model for standardised data, and a mixed beta-regression for unstandardised data, within a Bayesian framework. Our beta-regression approach performed better than models using standardised data, based on posterior predictive tests. The best model included region (Integrated Marine and Coastal Regionalisation of Australia (IMCRA bioregions, latitude and latitude squared. Removing region as an explanatory variable greatly reduced model performance (delta DIC 23.4. Several bioregions were identified as possessing notably high genetic diversity. Genetic diversity increased towards the equator with a 'hump' in diversity across the range studied (-9.4 to -43.7°S. Our results suggest that factors correlated with both region and latitude play a role in shaping intra-specific genetic diversity, and that bioregion can be a useful management unit for intra-specific as well as species biodiversity. Our novel statistical model should prove useful for future analyses of within species genetic diversity at broad taxonomic and geographic scales.

    Designing effective interventions to improve infant and young child (IYC) feeding requires knowledge about determinants of current practices, including cultural factors. Current approaches to obtaining and using research on culture tend to assume cultural homogeneity within a population. The purpose of this study was to examine the extent of cultural consensus (homogeneity) in communities where interventions to improve IYC feeding practices are needed to address undernutrition during the period of complementary feeding. A second, related objective was to identify the nature of intracultural variation, if such variation was evident. Selected protocols from the Focused Ethnographic Study for Infant and Young Child Feeding Manual were administered to samples of key informants and caregivers in a peri-urban and a rural area in Brong-Ahafo, Ghana. Cultural domain analysis techniques (free listing, caregiver assessment of culturally significant dimensions, and food ratings on these dimensions), as well as open-ended questions with exploratory probing, were used to obtain data on beliefs and related practices. Results reveal generally high cultural consensus on the 5 dimensions that were assessed (healthiness, appeal, child acceptance, convenience, and modernity) for caregiver decisions and on their ratings of individual foods. However, thematic analysis of caregiver narratives indicates that the meanings and content of the constructs connoted by the dimensions differed widely among individual mothers. These findings suggest that research on cultural factors that affect IYC practices, particularly cultural beliefs, should consider the nature and extent of cultural consensus and intracultural diversity, rather than assuming cultural homogeneity. © 2017 John Wiley & Sons Ltd.

  1. Morphological diversity between culture strains of a chlorarachniophyte, Lotharella globosa.

    Directory of Open Access Journals (Sweden)

    Yoshihisa Hirakawa

    Full Text Available Chlorarachniophytes are marine unicellular algae that possess secondary plastids of green algal origin. Although chlorarachniophytes are a small group (the phylum of Chlorarachniophyta contains 14 species in 8 genera, they have variable and complex life cycles that include amoeboid, coccoid, and/or flagellate cells. The majority of chlorarachniophytes possess two or more cell types in their life cycles, and which cell types are found is one of the principle morphological criteria used for species descriptions. Here we describe an unidentified chlorarachniophyte that was isolated from an artificial coral reef that calls this criterion into question. The life cycle of the new strain includes all three major cell types, but DNA barcoding based on the established nucleomorph ITS sequences showed it to share 100% sequence identity with Lotharella globosa. The type strain of L. globosa was also isolated from a coral reef, but is defined as completely lacking an amoeboid stage throughout its life cycle. We conclude that L. globosa possesses morphological diversity between culture strains, and that the new strain is a variety of L. globosa, which we describe as Lotharella globosa var. fortis var. nov. to include the amoeboid stage in the formal description of L. globosa. This intraspecies variation suggest that gross morphological stages maybe lost rather rapidly, and specifically that the type strain of L. globosa has lost the ability to form the amoeboid stage, perhaps recently. This in turn suggests that even major morphological characters used for taxonomy of this group may be variable in natural populations, and therefore misleading.

  3. Interactive diversity promotes the evolution of cooperation in structured populations

    Evolutionary games on networks traditionally assume that each individual adopts an identical strategy to interact with all its neighbors in each generation. Considering the prevalent diversity of individual interactions in the real society, here we propose the concept of interactive diversity, which allows individuals to adopt different strategies against different neighbors in each generation. We investigate the evolution of cooperation based on the edge dynamics rather than the traditional nodal dynamics in networked systems. The results show that, without invoking any other mechanisms, interactive diversity drives the frequency of cooperation to a high level for a wide range of parameters in both well-mixed and structured populations. Even in highly connected populations, cooperation still thrives. When interactive diversity and large topological heterogeneity are combined together, however, in the relaxed social dilemma, cooperation level is lower than that with just one of them, implying that the combination of many promotive factors may make a worse outcome. By an analytical approximation, we get the condition under which interactive diversity provides more advantages for cooperation than traditional evolutionary dynamics does. Numerical simulations validating the approximation are also presented. Our work provides a new line to explore the latent relation between the ubiquitous cooperation and individuals’ distinct responses in different interactions. The presented results suggest that interactive diversity should receive more attention in pursuing mechanisms fostering cooperation.

  4. Genetic diversity and population structure of cucumber (Cucumis sativus L..

    Directory of Open Access Journals (Sweden)

    Jing Lv

    Full Text Available Knowing the extent and structure of genetic variation in germplasm collections is essential for the conservation and utilization of biodiversity in cultivated plants. Cucumber is the fourth most important vegetable crop worldwide and is a model system for other Cucurbitaceae, a family that also includes melon, watermelon, pumpkin and squash. Previous isozyme studies revealed a low genetic diversity in cucumber, but detailed insights into the crop's genetic structure and diversity are largely missing. We have fingerprinted 3,342 accessions from the Chinese, Dutch and U.S. cucumber collections with 23 highly polymorphic Simple Sequence Repeat (SSR markers evenly distributed in the genome. The data reveal three distinct populations, largely corresponding to three geographic regions. Population 1 corresponds to germplasm from China, except for the unique semi-wild landraces found in Xishuangbanna in Southwest China and East Asia; population 2 to Europe, America, and Central and West Asia; and population 3 to India and Xishuangbanna. Admixtures were also detected, reflecting hybridization and migration events between the populations. The genetic background of the Indian germplasm is heterogeneous, indicating that the Indian cucumbers maintain a large proportion of the genetic diversity and that only a small fraction was introduced to other parts of the world. Subsequently, we defined a core collection consisting of 115 accessions and capturing over 77% of the SSR alleles. Insight into the genetic structure of cucumber will help developing appropriate conservation strategies and provides a basis for population-level genome sequencing in cucumber.

    Human and ecosystem health converge around biological diversity issues. Cultivated and wild plants as food and medicine make essential contributions to human health, which in turn provides rationales for conservation. While wild and cultivated plant diversity reasonably facilitates dietary diversity and positive health outcomes, the challenges of demonstrating this relationship limit its impact in concept, policy, and practice. We present a rationale for testing the dietary contribution of biological diversity to improved eye health as a case study based on existing phytochemical, pharmacological, and clinical knowledge. We consider the empirical evidence needed to substantiate, interpret, and apply this relationship at a population and ecosystem level within a unified research framework. Epidemiological data strongly support the prevention of childhood vitamin A deficiency blindness, cataract, and age-related macular degeneration by fruit and vegetable consumption. Phytonutrients, including the carotenoids lutein and zeaxanthin, protect the eye from oxidative stress and harmful light exposure. Laboratory, community, and population level research should prioritize food composition of dietary plants from both agriculture and the wild. Intervention studies, focus groups, and transmission of knowledge of local species and varieties within communities will further interpretation of epidemiological data. Population-based studies combining clinical data and measures of access and consumption of biological diversity are key to demonstrating the important relationships among biodiversity, dietary diversity, and health outcomes.

    The ikaite columns in the Ikka Fjord in Greenland represent one of the few permanently cold and alkaline environments on Earth, and the interior of the columns is home to a bacterial community adapted to these extreme conditions. The community is characterized by low cell numbers imbedded in a calcium carbonate matrix, making extraction of bacterial cells and DNA a challenge and limiting molecular and genomic studies of this environment. To utilize this genetic resource, cultivation at high pH and low temperature was studied as a method for obtaining biomass and DNA from the fraction of this community that would not otherwise be amenable to genetic analyses. The diversity and community dynamics in mixed cultures of bacteria from ikaite columns was investigated using denaturing gradient gel electrophoresis and pyrosequencing of 16S rDNA. Both medium composition and incubation time influenced the diversity of the culture and many hitherto uncharacterized genera could be brought into culture by extended incubation time. Extended incubation time also gave rise to a more diverse community with a significant number of rare species not detected in the initial community.

    2012-01-01

    At the Faculty of Health Sciences, Oslo University College there is a growing recognition of the need for cultural competency training among students at the bachelor programmes. At the Mensendieck-physiotherapy bachelor programme the students are engaged in leading physical activity groups for Muslim women. This qualitative study describes ethnically Norwegian students experiencing cultural diversity in practice. Twenty-two female physiotherapy students participated in the interviews; 6 students were interviewed individually by telephone, and 16 students were interviewed in person in 8 pairs. The students' framework for dealing with diversity is based on preconceived notions about Muslim women and is reflected in two particular ways. One is how the values and norms of Norwegian "ideology of sameness" are pursued by the students. The other is how the students constructed images of the women as "the others." The interview responses indicate difficulties in uniting the reality of diversity and the "need" for integration. The curriculum requires additional attention on cultural competency for health care professionals in a multicultural society.

    Nurses are educated to provide culturally competent care. Cultural competence begins with cultural awareness, a concept previously measured with the Cultural Awareness Scale (CAS). The purpose of this study was to reanalyze the CAS to determine construct validity and differences in cultural awareness among students of varying educational levels and experiences. The sample consisted of 150 nursing students (92% female, 33.6% racial minorities). Confirmatory factor analysis yielded three factors (CFI = 0.868, TLI = 0.854, RMSEA = 0.065, and SRMR = 0.086). Cronbach's alpha ranged from 0.70 to 0.89. There were significant differences among educational levels, with lower division BSN students generally scoring higher than upper division and master's of science in nursing students. Students who had taken courses on cultural diversity or global health generally outscored those who had not taken such courses. Findings support the validity of the CAS and its applicability to research studies of cultural awareness in nursing.

    The snakehead fish Channa argus is an important food fish in China. We identified six microsatellite loci for C. argus. These six microsatellite loci and four other microsatellite markers were used to analyze genetic diversity in four cultured populations of C. argus (SD, JX, HN, and ZJ) and determine their relationships. A total of 154 alleles were detected at the 10 microsatellite loci. The average expected and observed heterozygosities varied from 0.70-0.84 and 0.69-0.83, respectively, and polymorphism information content ranged between 0.66 and 0.82 in the four populations, indicating high genetic diversity. Population JX deviated from mutation-drift equilibrium and may have experienced a recent bottleneck. Analysis of pairwise genetic differentiation revealed FST values that ranged from 0.028 to 0.100, which indicates a moderate level of genetic differentiation. The largest distances were observed between populations HN and SD, whereas the smallest distances were obtained between populations HN and JX. Genetic clustering analysis demonstrated that the ZJ and HN populations probably share the same origin. This information about the genetic diversity within each of the four populations, and their genetic relationships will be useful for future genetic improvement of C. argus through selective breeding.

  12. Culturally Diverse Students in Higher Education: Challenges and Possibilities within Academic Literacy Practices

    2016-10-01

    Full Text Available With growing diversity in the population, higher education faces a new situation with increasing student diversity. In our paper, we will explore questions concerning the consequences student diversity has for higher-education institutions. Based on our experience from three different R&D projects, the differences in culture and academic literacy practices give culturally diverse students challenges that have often been ignored in academia. Some other studies also document that this group of students has a much higher risk of dropping out and underachieving than majority students (Andersen & Skaarer- Kreutz, 2007; Støren, 2009. In our paper, we are going to discuss the students’ challenges and discourse of remediation that is often associated with their challenges and suggest how higher-education institutions can adjust their practices to be more oriented to intercultural communication. Intercultural communication as a dialogic approach may create dynamics in academic tutoring and lead to mutual change/transformation instead of a one-way adaptation of existing academic literacy norms. We argue that all teachers should be aware of cultural differences in literacy practices in the education systems and strive to adjust their teaching practices to the diversity in the classroom. This approach, we believe, can contribute to a better learning environment for all students, independently of their backgrounds.

    In species subject to individual and social learning, each individual is likely to express a certain number of different cultural traits acquired during its lifetime. If the process of trait innovation and transmission reaches a steady state in the population, the number of different cultural traits carried by an individual converges to some stationary distribution. We call this the trait-number distribution. In this paper, we derive the trait-number distributions for both individuals and populations when cultural traits are independent of each other. Our results suggest that as the number of cultural traits becomes large, the trait-number distributions approach Poisson distributions so that their means characterize cultural diversity in the population. We then analyse how the mean trait number varies at both the individual and population levels as a function of various demographic features, such as population size and subdivision, and social learning rules, such as conformism and anti-conformism. Diversity at the individual and population levels, as well as at the level of cultural homogeneity within groups, depends critically on the details of population demography and the individual and social learning rules.

    Full Text Available The manifestation of ethnic, blood type, & gender-wise population variations regarding Dermatoglyphic manifestations are of interest to assess intra-group diversity and differentiation. The present study reports on the analysis of qualitaive and quantitative finger Dermatoglyphic traits of 382 individuals cross-sectionally sampled from an administrative region of Ethiopia, consisting of five ethnic cohorts from the Afro-Asiatic & Nilo-Saharan affiliations. These Dermatoglyphic parameters were then applied in the assessment of diversity & differentiation, including Heterozygosity, Fixation, Panmixia, Wahlund's variance, Nei's measure of genetic diversity, and thumb & finger pattern genotypes, which were inturn used in homology inferences as summarized by a Neighbour-Joining tree constructed from Nei's standard genetic distance. Results revealed significant correlation between Dermatoglyphics & population parameters that were further found to be in concordance with the historical accounts of the ethnic groups. Such inductions as the ancient north-eastern presence and subsequent admixure events of the Oromos (PII= 15.01, the high diversity of the Amharas (H= 0.1978, F= 0.6453, and P= 0.4144, and the Nilo-Saharan origin of the Berta group (PII= 10.66 are evidences to this. The study has further tested the possibility of applying Dermatoglyphics in population genetic & anthropologic research, highlighting on the prospect of developing a method to trace back population origins & ancient movement patterns. Additionally, linguistic clustering was deemed significant for the Ethiopian population, coinciding with recent genome wide studies that have ascertained that linguistic clustering as to being more crucial than the geographical patterning in the Ethiopian context. Finally, Dermatoglyphic markers have been proven to be endowed with a strong potential as non-invasive preliminary tools applicable prior to genetic studies to analyze ethnically sub

Results revealed significant correlation between Dermatoglyphics & population parameters that were further found to be in concordance with the historical accounts of the ethnic groups. Such inductions as the ancient north-eastern presence and subsequent admixure events of the Oromos (PII= 15.01), the high diversity of the Amharas (H= 0.1978, F= 0.6453, and P= 0.4144), and the Nilo-Saharan origin of the Berta group (PII= 10.66) are evidences to this. The study has further tested the possibility of applying Dermatoglyphics in population genetic & anthropologic research, highlighting on the prospect of developing a method to trace back population origins & ancient movement patterns. Additionally, linguistic clustering was deemed significant for the Ethiopian population, coinciding with recent genome wide studies that have ascertained that linguistic clustering as to being more crucial than the geographical patterning in the Ethiopian context. Finally, Dermatoglyphic markers have been proven to be endowed with a strong potential as non-invasive preliminary tools applicable prior to genetic studies to analyze ethnically sub-divided populations and

    Full Text Available Abstract Background Cultural competence, the ability to work in cross-cultural situations, has been acknowledged as a core skill for physiotherapists and other health professionals. Literature in this area has focused on the rationale for physiotherapists to provide culturally-competent care and the effectiveness of various educational strategies to facilitate the acquisition of knowledge about cultural competence by physiotherapists and physiotherapy students. However, there is a paucity of research on how students with different cultural needs, who are attending one university class, can be accommodated within a framework of learning core physiotherapy skills to achieve professional standards. Results This paper reports on steps which were taken to resolve the specific needs of a culturally-diverse body of first year physiotherapy students, and the impact this had on teaching in a new physiotherapy program located in Greater Western Sydney, Australia. Physiotherapy legislative, accreditation and registration requirements were considered in addition to anti-discrimination legislation and the four ethical principles of decision making. Conclusions Reflection on this issue and the steps taken to resolve it has resulted in the development of a generic framework which focuses on providing quality and equitable physiotherapy education opportunities to all students. This framework is generalizable to other health professions worldwide.

    The underrepresentation of ethnically diverse populations in cancer clinical trials results in the inequitable distribution of the risks and benefits of this research. Using a case study approach, we apply a conceptual framework of factors associated with the participation of diverse population groups in cancer clinical trials developed by Dr. Jean Ford and colleagues to increase understanding of the specific strategies, and barriers and promoters addressed by these strategies, that resulted in marked success in accrual of racially and ethnically diverse populations in cancer clinical research. Results indicate that the studies presented were able to successfully engage minority participants due to the creation and implementation of multilevel, multifaceted strategies that included: culturally and linguistically appropriate outreach, education, and research studies that were accessible in local communities; infrastructure to support engagement of key stakeholders, clinicians, and organizations serving minority communities; testimonials by ethnically diverse cancer survivors; availability of medical interpretation services; and providing infrastructure that facilitated the engagement in clinical research of clinicians who care for minority patient populations. These strategic efforts were effective in addressing limited awareness of trials, lack of opportunities to participate, and acceptance of engagement in cancer clinical trials. Careful attention to the context and population characteristics in which cancer clinical trials are conducted will be necessary to address disparities in research participation and cancer outcomes. These studies illustrate that progress on minority accrual into clinical research requires intentional efforts to overcome barriers at all three stages of the accrual process: awareness, opportunity, and acceptance of participation.

    Full Text Available The genetic basis of gene expression variation has long been studied with the aim to understand the landscape of regulatory variants, but also more recently to assist in the interpretation and elucidation of disease signals. To date, many studies have looked in specific tissues and population-based samples, but there has been limited assessment of the degree of inter-population variability in regulatory variation. We analyzed genome-wide gene expression in lymphoblastoid cell lines from a total of 726 individuals from 8 global populations from the HapMap3 project and correlated gene expression levels with HapMap3 SNPs located in cis to the genes. We describe the influence of ancestry on gene expression levels within and between these diverse human populations and uncover a non-negligible impact on global patterns of gene expression. We further dissect the specific functional pathways differentiated between populations. We also identify 5,691 expression quantitative trait loci (eQTLs after controlling for both non-genetic factors and population admixture and observe that half of the cis-eQTLs are replicated in one or more of the populations. We highlight patterns of eQTL-sharing between populations, which are partially determined by population genetic relatedness, and discover significant sharing of eQTL effects between Asians, European-admixed, and African subpopulations. Specifically, we observe that both the effect size and the direction of effect for eQTLs are highly conserved across populations. We observe an increasing proximity of eQTLs toward the transcription start site as sharing of eQTLs among populations increases, highlighting that variants close to TSS have stronger effects and therefore are more likely to be detected across a wider panel of populations. Together these results offer a unique picture and resource of the degree of differentiation among human populations in functional regulatory variation and provide an estimate for

I distinguish social roles and related social network structures and discuss ways in which each might maintain diversity. I suggest that cognitive analogs of "cohesion," a property of networks that helps maintenance of diversity, might mediate the effects of social roles on diversity.

    Maintenance and management of genetic diversity of farm animal genetic resources (AnGR) is very important for biological, socioeconomical and cultural significance. The core concern of conservation for farm AnGR is the retention of genetic diversity of conserved populations in a long-term perspective. However, numerous factors may affect evolution of genetic diversity of a conserved population. Among those factors, the genetic architecture of conserved populations is little considered in current conservation strategies. In this study, we investigated the dynamic changes of genetic diversity of conserved populations with two scenarios on initial genetic architectures by computer simulation in which thirty polymorphic microsatellite loci were chosen to represent genetic architecture of the populations with observed heterozygosity (Ho) and expected heterozygosity (He), observed and mean effective number of alleles (Ao and Ae), number of polymorphic loci (NP) and the percentage of polymorphic loci (PP), number of rare alleles (RA) and number of non-rich polymorphic loci (NRP) as the estimates of genetic diversity. The two scenarios on genetic architecture were taken into account, namely, one conserved population with same allele frequency (AS) and another one with actual allele frequency (AA). The results showed that the magnitude of loss of genetic diversity is associated with genetic architecture of initial conserved population, the amplitude of genetic diversity decline in the context AS was more narrow extent than those in context AA, the ranges of decline of Ho and Ao were about 4 and 2 times in AA compared with that in AS, respectively, the occurrence of first monomorphic locus and the time of change of measure NP in scenario AA is 20 generations and 23 generations earlier than that in scenario AS, respectively. Additionally, we found that NRP, a novel measure proposed by our research group, was a proper estimate for monitoring the evolution of genetic diversity

    Full Text Available Cultural diversity plays today a prominent role in the updating and developing of human rights. Past developments in the protection of rights have essentially forgotten the democratic management of cultural and identity-based diversity. States have stifled the main developments of the rights and constrained them to partial views in favour of the majority or dominant groups in each country. The current context of regional progressive integration and social diversification within each state agrees on the need to address the adequacy of systems for the protection of rights from different strategies to the context of multiculturalism. Against the process of "nationalization of rights" it is necessary to adopt a strategy for pluralization. On the one hand, the concept of minority has to be given its corresponding importance in both international and domestic law. On the other hand, different kind of policies and legal instruments for the accommodation of diversity can be identified and used to foster this necessary process of pluralization.

    Analysis of Gammarus fossarum populations from mountain torrents in the Grenoble region reveals some morphological and eco physiological diversity which appears to be related to the calcium concentration of the water after both field and laboratory experimentation. Animals from waters with a high calcium concentration (located in Chartreuse and Vercors) show larger size and a longer molt cycle than those from low calcium concentrated waters (located in Belledonne); their calcium balance during the molt cycle is different. Translocation experiments confirm these differences: a significant increase of the duration of the molt cycle is observed in animals translocated to lower calcium concentrated waters and vice-versa whereas no significant difference is observed between controls and animals translocated within comparably calcium concentrated waters. The causes of such an adaptative diversity between Gammarus fossarum populations will be researched at the genetic level, namely through mitochondrial DNA investigations.

    In-depth understanding of cultural and religious factors limiting organ donation of three ethnic populations (Malay, Chinese, and Indian) in Southeast Asia is lacking. Identification of factors limiting organ donation among these three ethnic groups will provide insights into culturally appropriate strategies to promote acceptance of organ donation in a multiethnic Asian community. A total of 17 focus group discussions (105 participants) were conducted between September and December 2008. Participants were members of the general public aged 18 to 60 years, recruited through convenient sampling around the Klang Valley area of Malaysia. Although the majority had favorable attitudes toward deceased organ donation and transplantation, a diversity of myths and misinformation were unearthed from the discussions across the ethnic groups. These include perceived religious prohibition, cultural myths and misperceptions, fear of disfigurement, fear of surgery, distrust of the medical system, and family disapproval. Culture and religious beliefs played important prohibitive roles among those opposed to organ donations. There were distinctive ethnic differences in cultural and religious concerns regarding organ donation. Less-educated and rural groups appeared to have more misconceptions than the well-educated and the urban groups. Our findings may assist organ donation and transplantation organizations to reach diverse sociodemographic and ethnic communities with culture-specific information about organ donation. The involvement of community and religious leaders is critical in organ donation requests.

    The National Health Service (NHS) Local Improvement Finance Trust (LIFT) programme was launched in 2001 as an innovative public-private partnership to address the historical under-investment in local primary care facilities in England. The organisations from the public and private sector that comprise a local LIFT partnership each have their own distinctive norms of behaviour and acceptable working practices - ultimately different organisational cultures. The purpose of this article is to assess the role of organisational culture in facilitating (or impeding) LIFT partnerships and to contribute to an understanding of how cultural diversity in public-private partnerships is managed at the local level. The approach taken was qualitative case studies, with data gathering comprising interviews and a review of background documentation in three LIFT companies purposefully sampled to represent a range of background factors. Elite interviews were also conducted with senior policy makers responsible for implementing LIFT policy at the national level. Interpreting the data against a conceptual framework designed to assess approaches to managing strategic alliances, the authors identified a number of key differences in the values, working practices and cultures in public and private organisations that influenced the quality of joint working. On the whole, however, partners in the three LIFT companies appeared to be working well together, with neither side dominating the development of strategy. Differences in culture were being managed and accommodated as partnerships matured. As LIFT develops and becomes the primary source of investment for managing, developing and channelling funding into regenerating the primary care infrastructure, further longitudinal work might examine how ongoing partnerships are working, and how changes in the cultures of public and private partners impact upon wider relationships within local health economies and shape the delivery of patient care

    The 2007 position statement on diversity for the Canadian occupational therapy profession argued discussion was needed to determine the implications of approaches to working with cultural differences and other forms of diversity. In 2014, a new position statement on diversity was published, emphasizing the importance of social power relations and power relations between client and therapist, and supporting two particular approaches: cultural safety and cultural humility with critical reflexivity This paper reviews and critically synthesizes the literature concerning culture and diversity published in occupational therapy between 2007 and 2014, tracing the major discourses and mapping the implications of four differing approaches: cultural competence, cultural relevance, cultural safety, and cultural humility. Approaches differ in where they situate the "problem," how they envision change, the end goal, and the application to a range of types of diversity. The latter two are preferred approaches for their attention to power relations and potential to encompass a range of types of social and cultural diversity. © CAOT 2015.

    Germplasm diversity is the mainstay for crop improvement and genetic dissection of complex traits. Understanding genetic diversity, population structure, and the level and distribution of linkage disequilibrium (LD) in target populations is of great importance and a prerequisite for association mapping. In this study, 100 genome-wide simple sequence repeat (SSR) markers were used to assess genetic diversity, population structure, and LD of 416 rice accessions including landraces, cultivars and breeding lines collected mostly in China. A model-based population structure analysis divided the rice materials into seven subpopulations. 63% of the SSR pairs in these accessions were in LD, which was mostly due to an overall population structure, since the number of locus pairs in LD was reduced sharply within each subpopulation, with the SSR pairs in LD ranging from 5.9 to 22.9%. Among those SSR pairs showing significant LD, the intrachromosomal LD had an average of 25-50 cM in different subpopulations. Analysis of the phenotypic diversity of 25 traits showed that the population structure accounted for an average of 22.4% of phenotypic variation. An example association mapping for starch quality traits using both the candidate gene mapping and genome-wide mapping strategies based on the estimated population structure was conducted. Candidate gene mapping confirmed that the Wx and starch synthase IIa (SSIIa) genes could be identified as strongly associated with apparent amylose content (AAC) and pasting temperature (PT), respectively. More importantly, we revealed that the Wx gene was also strongly associated with PT. In addition to the major genes, we found five and seven SSRs were associated with AAC and PT, respectively, some of which have not been detected in previous linkage mapping studies. The results suggested that the population may be useful for the genome-wide marker-trait association mapping. This new association population has the potential to identify

    Full Text Available This study assesses managerial perceptions of the management of cultural diversity and workplace transformation in three production companies in Gauteng. A sample comprising 668 employees was drawn from a population of 1 259 (53% response rate using simple random sampling and data were collected through self-developed questionnaires and personal interviews. Data were analysed using descriptive and inferential statistics. The results indicate that whilst the South African Transformation (SAT Agenda has propelled change in the political and economic spheres, similar developments have not been realised in the South African labour market. Hence, based on the findings, recommendations are made to enhance the management of cultural diversity and workplace transformation, and the need for urgent government intervention, through legislative amendments, is emphasised.

    Full Text Available One Culture or Multiple Cultures? The Diversity of Roma People in Poland There are no universal criteria which would be useful to describe the diversity of all of the Roma. Their presence in given country is linked to adaptive processes to majority societies. It is the majority that creates condition and space to which minorities need to adapt somehow. The results of the above-mentioned adaptive processes also vary and depend on an external context. The attitude of given populations towards minorities and the current political and economic situation of given country, where the Roma settled had and still has significant influence on mentioned processes. The way of life of different Romani groups has also a great importance, because sedentary way of life (typical for most European Roma and external influences especially on culture and models of lifestyle also furthered the adaptive processes. The cultural diversity among the Roma is the case not only with the groups living in different countries. It needs to be emphasized that the Roma who have lived in one country for centuries are not a homogenous group in terms of their culture. Previous migration processes and sedentary or nomadic way of life had a great influence on this internal diversity. In Poland with four distinguished Romani groups such diversity occurs between Carpathian Roma (Bergitka Roma, Polish Highlander Roma and traditionally nomadic groups: Polska Roma, Lovara, Kelderari. This article is mainly based on available sources and dissertations on the subject. However it refers to the field research regarding the use of European Union’s funds for the Roma community in Poland, which was conducted by the author in 2010 and 2011.   Kultura jedna czy wieloraka?

    Full Text Available Theileriosis, caused by a number of species within the genus Theileria, is a common disease of livestock in Oman. It is a major constraint to the development of the livestock industry due to a high rate of morbidity and mortality in both cattle and sheep. Since little is currently known about the genetic diversity of the parasites causing theileriosis in Oman, the present study was designed to address this issue with specific regard to T. annulata in cattle.Blood samples were collected from cattle from four geographically distinct regions in Oman for genetic analysis of the Theileria annulata population. Ten genetic markers (micro- and mini-satellites representing all four chromosomes of T. annulata were applied to these samples using a combination of PCR amplification and fragment analysis. The resultant genetic data was analysed to provide a first insight into the structure of the T. annulata population in Oman.We applied ten micro- and mini-satellite markers to a total of 310 samples obtained from different regions (174 [56%] from Dhofar, 68 [22%] from Dhira, 44 [14.5%] from Batinah and 24 [8%] from Sharqia. A high degree of allelic diversity was observed among the four parasite populations. Expected heterozygosity for each site ranged from 0.816 to 0.854. A high multiplicity of infection was observed in individual hosts, with an average of 3.3 to 3.4 alleles per locus, in samples derived from Batinah, Dhofar and Sharqia regions. In samples from Dhira region, an average of 2.9 alleles per locus was observed. Mild but statistically significant linkage disequilibrium between pairs of markers was observed in populations from three of the four regions. In contrast, when the analysis was performed at farm level, no significant linkage disequilibrium was observed. Finally, no significant genetic differentiation was seen between the four populations, with most pair-wise FST values being less than 0.03. Slightly higher FST values (GST' = 0.075,

    South American camelids (SACs) have a major role in the maintenance and potential future of rural Andean human populations. More than 60% of the 3.7 million llamas living worldwide are found in Bolivia. Due to the lack of studies focusing on genetic diversity in Bolivian llamas, this analysis investigates both the genetic diversity and structure of 12 regional groups of llamas that span the greater part of the range of distribution for this species in Bolivia. The analysis of 42 microsatellite markers in the considered regional groups showed that, in general, there were high levels of polymorphism (a total of 506 detected alleles; average PIC across per marker: 0.66), which are comparable with those reported for other populations of domestic SACs. The estimated diversity parameters indicated that there was high intrapopulational genetic variation (average number of alleles and average expected heterozygosity per marker: 12.04 and 0.68, respectively) and weak genetic differentiation among populations (FST range: 0.003-0.052). In agreement with these estimates, Bolivian llamas showed a weak genetic structure and an intense gene flow between all the studied regional groups, which is due to the exchange of reproductive males between the different flocks. Interestingly, the groups for which the largest pairwise FST estimates were observed, Sud Lípez and Nor Lípez, showed a certain level of genetic differentiation that is probably due to the pattern of geographic isolation and limited communication infrastructures of these southern localities. Overall, the population parameters reported here may serve as a reference when establishing conservation policies that address Bolivian llama populations.

    Moose (Alces alces) are highly mobile mammals that occur across arboreal regions of North America, Europe, and Asia. Alaskan moose (Alces alces gigas) range across much of Alaska and are primary herbivore consumers, exerting a prominent influence on ecosystem structure and functioning. Increased knowledge gained from population genetics provides insights into their population dynamics, history, and dispersal of these unique large herbivores and can aid in conservation efforts. We examined the genetic diversity and population structure of moose (n = 141) with 8 polymorphic microsatellites from 6 regions spanning much of Alaska. Expected heterozygosity was moderate (H(E) = 0.483-0.612), and private alleles ranged from 0 to 6. Both F(ST) and R(ST) indicated significant population structure (P moose from the Yakutat and Tetlin regions versus all other moose, with slight substructure observed among the second population. Estimates of dispersal differed between analytical approaches, indicating a high level of historical or current gene flow. Mantel tests indicated that isolation-by-distance partially explained observed structure among moose populations (R(2) = 0.45, P moose in Alaska with population expansion from interior Alaska westward toward the coast.

  1. The statistics of genetic diversity in rapidly adapting populations.

    2013-03-01

    Evolutionary adaptation is driven by the accumulation of beneficial mutations, but the sequence-level dynamics of this process are poorly understood. The traditional view is that adaptation is dominated by rare beneficial ``driver'' mutations that occur sporadically and then rapidly increase in frequency until they fix (a ``selective sweep''). Yet in microbial populations, multiple beneficial mutations are often present simultaneously. Selection cannot act on each mutation independently, but only on linked combinations. This means that the fate of any mutation depends on a complex interplay between its own fitness effect, the genomic background in which it arises, and the rest of the sequence variation in the population. The balance between these factors determines which mutations fix, the patterns of sequence diversity within populations, and the degree to which evolution in replicate populations will follow parallel (or divergent) trajectories at the sequence level. Earlier work has uncovered signatures of these effects, but the dynamics of genomic sequence evolution in adapting microbial populations have not yet been directly observed. In this talk, I will describe how full-genome whole-population sequencing can be used to provide a detailed view of these dynamics at high temporal resolution over 1000 generations in 40 adapting Saccharomyces cerevisiaepopulations. This data shows how patterns of sequence evolution are driven by a balance between chance interference and hitchhiking effects, which increase stochastic variation in evolutionary outcomes, and the deterministic action of selection on individual mutations, which favors parallel solutions in replicate populations.

    Lactobacillus delbrueckii subsp. bulgaricus is one of the most widely used starter culture strains in industrial fermented dairy manufacture. It is also common in naturally fermented dairy foods made using traditional methods. The subsp. bulgaricus strains found in naturally fermented foods may be useful for improving current industrial starter cultures; however, little is known regarding its genetic diversity and population structure. Here, a collection of 298 L. delbrueckii strains from naturally fermented products in Mongolia, Russia, and West China was analyzed by multi-locus sequence typing based on eight conserved genes. The 251 confirmed subsp. bulgaricus strains produced 106 unique sequence types, the majority of which were assigned to five clonal complexes (CCs). The geographical distribution of CCs was uneven, with CC1 dominated by Mongolian and Russian isolates, and CC2-CC5 isolates exclusively from Xinjiang, China. Population structure analysis suggested six lineages, L1-L6, with various homologous recombination rates. Although L2-L5 were mainly restricted within specific regions, strains belonging to L1 and L6 were observed in diverse regions, suggesting historical transmission events. These results greatly enhance our knowledge of the population diversity of subsp. bulgaricus strains, and suggest that strains from CC1 and L4 may be useful as starter strains in industrial fermentation.

    Mitochondrial DNA is a useful marker for population studies, human identification, and forensic analysis. Commonly used hypervariable regions I and II (HVI/HVII) were reported to contain as little as 25% of mitochondrial DNA variants and therefore the majority of power of discrimination of mitochondrial DNA resides in the coding region. Massively parallel sequencing technology enables entire mitochondrial genome sequencing. In this study, buccal swabs were collected from 114 unrelated Estonians and whole mitochondrial genome sequences were generated using the Illumina MiSeq system. The results are concordant with previous mtDNA control region reports of high haplogroup HV and U frequencies (47.4 and 23.7% in this study, respectively) in the Estonian population. One sample with the Northern Asian haplogroup D was detected. The genetic diversity of the Estonian population sample was estimated to be 99.67 and 95.85%, for mtGenome and HVI/HVII data, respectively. The random match probability for mtGenome data was 1.20 versus 4.99% for HVI/HVII. The nucleotide mean pairwise difference was 27 ± 11 for mtGenome and 7 ± 3 for HVI/HVII data. These data describe the genetic diversity of the Estonian population sample and emphasize the power of discrimination of the entire mitochondrial genome over the hypervariable regions.

    Microsatellite loci are widely used for investigating patterns of genetic variation within and among populations. Those patterns are in turn determined by population sizes, migration rates, and mutation rates. We provide exact expressions for the first two moments of the allele frequency distribution in a stochastic model appropriate for studying microsatellite evolution with migration, mutation, and drift under the assumption that the range of allele sizes is bounded. Using these results, we study the behavior of several measures related to Wright's F(ST), including Slatkin's R(ST). Our analytical approximations for F(ST) and R(ST) show that familiar relationships between N(e)m and F(ST) or R(ST) hold when the migration and mutation rates are small. Using the exact expressions for F(ST) and R(ST), our numerical results show that, when the migration and mutation rates are large, these relationships no longer hold. Our numerical results also show that the diversity measures most closely related to F(ST) depend on mutation rates, mutational models (stepwise versus two-phase), migration rates, and population sizes. Surprisingly, R(ST) is relatively insensitive to the mutation rates and mutational models. The differing behaviors of R(ST) and F(ST) suggest that properties of the among-population distribution of allele frequencies may allow the roles of mutation and migration in producing patterns of diversity to be distinguished, a topic of continuing investigation.

    The ancient silk road of China passed through Xinjiang and facilitated gene exchanges from the East and the West which impacted on the genetic variation and structure of the nomadic Kazakh population residing there. In order to understand the nature of this genetic variation; 151 Xinjiang Kazakh samples were obtained from four main Kazakh groups and were analyzed using mtDNA and Y-chromosome markers. The Xinjiang Kazakh population is heterogeneous, showing the coexistence of matrilineal lineages with different origins. No genetic differentiation of mtDNA is observed among the four different regional Xinjiang Kazakh populations in Xinjiang by AMOVA and Networks. The genetic diversity of Y-STR loci is higher in Xinjiang Kazakhs (0.968 ± 0.014) than the Kazakhs from Kazakhstan (0.629 ± 0.071) and Russia (0.835 ± 0.020). East Eurasians make a more than 50% contribution to the maternal and paternal lineages of Xinjiang Kazakhs. There is more gene flow from West Eurasian into the maternal lineages of Xinjiang Kazakh than to the Kazakhs from Russia and Kazakhstan. Moreover, mtDNA and Y-STR displayed high polymorphism in Xinjiang Kazakhs (the haplotype diversity and power of discrimination were 0.990 ± 0.003, 0.9137 for mtDNA HVS and 0.968 ± 0.014, 0.9489 for Y-STR system, respectively), suggesting they would be very useful and important markers for forensic analysis and population genetic studies.

    RAPD analysis was used to examine the extent of genetic polymorphism in two populations of Gentoo penguin (Pygoscelis papua) from Antarctic Islands (Petermann and Livingston). The chosen two of three 10 mer oligonucleotide primers accordingly to preliminary results showed different levels of polymorphism in Gentoo penguins at Petermann Island (from 23.53 to 42.86%) and Livingston Island (from 52.94 to 57.14%). Nei's similarity coefficients were in range from 0.5606 (when Gentoo genome profiles were compared with RAPD profiles of two related penguin species: Pygoscelis adeliae (Adelie) and Pygoscelis antarctica (Chinstrep)) to 0.9281 among observed Gentoo penguin populations. Nei's distances values ranged from 0.0746 to 0.5787 among the populations and species. The obtained results will be used for further estimation of genetic diversity of Gentoo penguins and determination of their taxonomic status.

    To examine the perceptions of a group of culturally and linguistically diverse participants with the comorbidities of diabetes, chronic kidney disease and cardiovascular disease to determine factors that influence their medication self-efficacy through the use of motivational interviewing. These comorbidities are a global public health problem and their self-management is more difficult for culturally and linguistically diverse populations living in English-speaking communities. Few interventions have been tested in culturally and linguistically diverse people to improve their medication self-efficacy. A series of motivational interviewing telephone calls were conducted in the intervention arm of a randomised controlled trial using interpreter services. Patients with these comorbidities aged ≥18 years of age whose preference it was to speak Greek, Italian or Vietnamese were recruited from nephrology outpatient clinics of two Australian metropolitan hospitals in 2009. The average age of the 26 participants was 73·5 years. The fortnightly calls averaged 9·5 minutes. Thematic analysis revealed three core themes which were attitudes towards medication, having to take medication and impediments to chronic illness medication self-efficacy. A lack of knowledge about medications impeded confidence necessary for optimal disease self-management. Participants had limited access to resources to help them understand their medications. This work has highlighted communication gaps and barriers affecting medication self-efficacy in this group. Culturally sensitive interventions are required to ensure people of culturally and linguistically diverse backgrounds have the appropriate skills to self-manage their complex medical conditions. Helping people to take their medications as prescribed is a key role for nurses to serve and protect the well-being of our increasingly multicultural communities. The use of interpreters in motivational interviewing requires careful planning and

    The ascomycetous fungus Cryphonectria parasitica (Murr.) is one of the most important fungal pathogens of chestnut (Castanea sativa Mill.), causing chestnut blight. It is originated from Eastern Asia and was introduced into North America, and later into Europe. Almost 100 C. parasitica isolates were collected mainly from the Carpathian Basin to study their diversity and phylogenetic relationships. Three nuclear molecular markers were tested: (i) internal transcribed spacers (ITS), (ii) translation elongation factor 1 subunit alpha (tef1), and (iii) six microsatellite loci. The ITS region proved to be highly polymorphic but this kind of variability did not reflect the geographical regions of the isolates, while the tef1 sequences were identical in all isolates. Microsatellite haplotype diversity was relatively high (0.923-0.984) calculated for the fungal populations of the Carpathian Basin. This may have resulted from the multiple introductions from diverse origins of the populations, close to the first site of observation in Northern Italy. The BAPS analysis of the microsatellite markers occasionally grouped together samples from remote geographical origin, suggesting human assistance in the introduction of new C. parasitica haplotypes from distinct areas.

    We report the Simons Genome Diversity Project (SGDP) dataset: high quality genomes from 300 individuals from 142 diverse populations. These genomes include at least 5.8 million base pairs that are not present in the human reference genome. Our analysis reveals key features of the landscape of human genome variation, including that the rate of accumulation of mutations has accelerated by about 5% in non-Africans compared to Africans since divergence. We show that the ancestors of some pairs of present-day human populations were substantially separated by 100,000 years ago, well before the archaeologically attested onset of behavioral modernity. We also demonstrate that indigenous Australians, New Guineans and Andamanese do not derive substantial ancestry from an early dispersal of modern humans; instead, their modern human ancestry is consistent with coming from the same source as that in other non-Africans.

    Genetic diversity generally underpins population resilience and persistence. Reductions in population size and absence of gene flow can lead to reductions in genetic diversity, reproductive fitness, and a limited ability to adapt to environmental change increasing the risk of extinction. Island populations are typically small and isolated, and as a result, inbreeding and reduced genetic diversity elevate their extinction risk. Two island populations of the platypus, Ornithorhynchus anatinus, exist; a naturally occurring population on King Island in Bass Strait and a recently introduced population on Kangaroo Island off the coast of South Australia. Here we assessed the genetic diversity within these two island populations and contrasted these patterns with genetic diversity estimates in areas from which the populations are likely to have been founded. On Kangaroo Island, we also modeled live capture data to determine estimates of population size. Levels of genetic diversity in King Island platypuses are perilously low, with eight of 13 microsatellite loci fixed, likely reflecting their small population size and prolonged isolation. Estimates of heterozygosity detected by microsatellites (H(E)= 0.032) are among the lowest level of genetic diversity recorded by this method in a naturally outbreeding vertebrate population. In contrast, estimates of genetic diversity on Kangaroo Island are somewhat higher. However, estimates of small population size and the limited founders combined with genetic isolation are likely to lead to further losses of genetic diversity through time for the Kangaroo Island platypus population. Implications for the future of these and similarly isolated or genetically depauperate populations are discussed.

    In the departments of the Vaupés and Guaviare, in southeastern Colombia, in a transitional area between Amazonia and the eastern plains, inhabit indigenous groups belonging to the Tukanoan (East) and Guahiban linguistic families. Although some studies have dealt with the culture and the cosmology description of these groups, little research has been done on the biological diversity and genetic relationships of such groups. To estimate the diversity, the structure, and the genetic relationships of one Guahiban and two Tukanoan groups of the Colombian Amazonian region. Samples were collected (n = 106) from unrelated individuals belonging to the Vaupés native indigenous communities. The DNA was extracted and nine autosomal microsatellites were typed. Several measures of diversity, FST, pairwise FST, and population differentiation between groups were calculated. Finally, it was estimated the genetic distances of the groups studied in relation with other Amazonian, Andean and Central American indigenous people. 1. The genetic diversity found stands within the range of other Amazonian populations, whereas compared to the mestizo and afro-descendant Colombian populations, such diversity showed to be lower. 2. The structure and population differentiation tests showed two clusters; one consisting of the Vaupés Tukanoan and Guaviare Tukanoan groups, and a second one formed by the Guayabero. 3. Tukanoan groups are found to be closer related to the Brazilian Amazonian populations than to the Guayabero. The results of this study suggest that the Guayabero group from Guaviare, are genetically differentiated from those Tukanoan groups of the Vaupés and Guaviare.

  15. Genetic diversity in Chilean populations of rainbow trout, Oncorhynchus mykiss

    Full Text Available The rainbow trout Oncorhynchus mykiss, was first introduced in Chile between 1905 and 1920 and is currently widely distributed in Chile from Antofagasta (23°S to Patagonia (55°S. The broad range of the geographic and climatic distributions of this species in Chile offers a unique opportunity to study the effect of naturalization of an introduced species on its genetic variability. It is of particular importance to observe the genetic variability of populations in the northern range of this species distribution, in a transition zone where a Mediterranean-type climate changes to an arid climate. The present study analyzed allozymic variability and distribution within and between populations of O. mykiss from the river basins of Elqui and Limari rivers, and six culture strains, using starch-gel protein electrophoresis. Populations were found to be in Hardy-Weinberg equilibrium and the average values of He (0.045, polymorphism (13.9% and allele per locus (1.19 are similar to rainbow trout in its native distributional range. About 77.8% of the genetic variability was within population, similar to the variability reported for wild populations in the northern hemisphere. However, a marked genetic differentiation between wild populations was also found. This is likely to be the consequence of initial founder effects followed by subsequent introgression of resident populations caused by reseeding with trout of different origins in both basins.

  16. Addressing cultural diversity: the hepatitis B clinical specialist perspective.

    Hepatitis B is a viral infection primarily affecting people from culturally diverse communities in Australia. While vaccination prevents infection, there is increasing mortality resulting from liver damage associated with chronic infection. Deficits in the national policy and clinical response to hepatitis B result in a low diagnosis rate, inadequate testing and diagnosis processes, and poor access to hepatitis B treatment services. While research identifies inadequate hepatitis B knowledge among people with the virus and primary health care workers, this project sought to identify how specialist clinicians in Australia negotiate cultural diversity, and provide often complex clinical information to people with hepatitis B. A vignette was developed and presented to thirteen viral hepatitis specialist clinicians prior to an electronically recorded interview. Recruitment continued until saturation of themes was reached. Data were thematically coded into themes outlined in the interview schedule. Ethical approval for the research was provided by the La Trobe University Human Research Ethics Committee. Key messages provided to patients with hepatitis B by clinical specialists were identified. These messages were not consistently provided to all patients with hepatitis B, but were determined on perceptions of patient knowledge, age and highest educational level. While the vignette stated that English was not an issue for the patient, most specialists identified the need for an interpreter. Combating stigma related to hepatitis B was seen as important by the specialists and this was done through normalising the virus. Having an awareness of different cultural understandings about hepatitis B specifically, and health and well-being generally, was noted as a communication strategy. Key core competencies need to be developed to deliver educational messages to people with hepatitis B within clinical encounters. The provision of adequate resources to specialist clinics will

    Apicomplexan parasites include many parasites of importance either for livestock or as causative agents of human diseases. The importance of these parasites has been recognised by the European Commission and resulted in support of the COST (Cooperation in Science and Technology) Action 857 'Apicomplexan Biology in the Post-Genomic Era'. In this review we discuss the current understanding in 'Biodiversity and Population Genetics' of the major apicomplexan parasites, namely the Eimeria spp., Cryptosporidium spp., Toxoplasma gondii, Neospora caninum, Theileria spp. and Plasmodium spp. During the past decade molecular tools for characterizing and monitoring parasite populations have been firmly established as an integral part of field studies and intervention trials. Analyses have been conducted for most apicomplexan pathogens to describe the extent of genetic diversity, infection dynamics or population structure. The underlying key question for all parasites is to understand how genetic diversity influences epidemiology and pathogenicity and its implication in therapeutic and vaccination strategies as well as disease control. Similarities in the basic biology and disease or transmission patterns among this order of parasites promote multifaceted discussions and comparison of epidemiological approaches and methodological tools. This fosters mutual learning and has the potential for cross-fertilisation of ideas and technical approaches.

    The genus Theobroma found in the Amazon region is composed of 22 species, including Theobroma speciosum, better known as cacauí. These species are constantly threatened by forest fragmentation caused by human activities and require conservation strategies and management aimed at preserving them in their natural environments. The main objective of this study was to analyze the population structure and genetic diversity within and between natural populations of T. speciosum by using ISSR molecular markers to understand the population structure of the species. Four natural populations belonging to the Amazon rainforest (BAC, CRO, FLA, and PNA), located in the State of Mato Grosso, were selected. Amplification reactions were performed using 15 ISSR primers. A total of 101 loci were found, of which 54.46% were polymorphic at the species level. The BAC population showed higher genetic diversity (H=0.095 and I=0.144) and higher percentage of polymorphism (28.71%). The populations showed an FST value of 0.604, indicating marked genetic differentiation. The highest genetic variation was found between populations. Gene flow was low between populations, indicating genetic isolation between populations.

    The application of primary organoid cultures containing epithelial and mesenchymal elements to cancer modeling holds promise for combining the accurate multilineage differentiation and physiology of in vivo systems with the facile in vitro manipulation of transformed cell lines. Here we used a single air-liquid interface culture method without modification to engineer oncogenic mutations into primary epithelial and mesenchymal organoids from mouse colon, stomach and pancreas. Pancreatic and gastric organoids exhibited dysplasia as a result of expression of Kras carrying the G12D mutation (Kras(G12D)), p53 loss or both and readily generated adenocarcinoma after in vivo transplantation. In contrast, primary colon organoids required combinatorial Apc, p53, Kras(G12D) and Smad4 mutations for progressive transformation to invasive adenocarcinoma-like histology in vitro and tumorigenicity in vivo, recapitulating multi-hit models of colorectal cancer (CRC), as compared to the more promiscuous transformation of small intestinal organoids. Colon organoid culture functionally validated the microRNA miR-483 as a dominant driver oncogene at the IGF2 (insulin-like growth factor-2) 11p15.5 CRC amplicon, inducing dysplasia in vitro and tumorigenicity in vivo. These studies demonstrate the general utility of a highly tractable primary organoid system for cancer modeling and driver oncogene validation in diverse gastrointestinal tissues.

    Cultural competency or the ongoing capacity of health care systems to provide for high-quality care to diverse patient populations (National Quality Forum, 2008) has been proposed as an organizational strategy to address disparities in quality of care, patient experience, and workforce representation. But far too many health care organizations still do not treat cultural competency as a business imperative and driver of strategy. The aim of the study was to examine the impact of a systematic, multifaceted, and organizational level cultural competency initiative on hospital performance metrics at the organizational and individual levels. This demonstration project employs a pre-post control group design. Two hospital systems participated in the study. Within each system, two hospitals were selected to serve as the intervention and control hospitals. Executive leadership (C-suite) and all staff at one general medical/surgical nursing unit at the intervention hospitals experienced a systematic, planned cultural competency intervention. Assessments and interventions focused on three organizational level competencies of cultural competency (diversity leadership, strategic human resource management, and patient cultural competency) and three individual level competencies (diversity attitudes, implicit bias, and racial/ethnic identity status). In addition, we evaluated the impact of the intervention on diversity climate and workforce diversity. Overall performance improvement was greater in each of the two intervention hospitals than in the control hospital within the same health care system. Both intervention hospitals experienced improvements in the organizational level competencies of diversity leadership and strategic human resource management. Similarly, improvements were observed in the individual level competencies for diversity attitudes and implicit bias for Blacks among the intervention hospitals. Furthermore, intervention hospitals outperformed their respective

    Full Text Available Telepractice is the application of telecommunications technology to the delivery of telehealth services via the online connection of clinicians, clients, and patients for assessment, intervention, or consultation.  This article describes a pilot project in which speech-language pathology students in a university training program gained experience in working with culturally diverse preschool students using telepractice technology. The preschool students benefited by making gains in communication skills, while the university students acquired competency in the use of telepractice and in working with children whose cultural and linguistic backgrounds were outside of their experience.  To assess the training experience, a Likert-scale survey administered to student clinicians revealed a high degree of satisfaction and improved familiarity with the use of telepractice, and an increased comfort level working with multi-cultural populations.

    Full Text Available This study investigated cultural aspects of conflict management in organizations in response to the growing need for an understanding of how people from diverse cultural backgrounds can work together without the often-resulting problem of intercultural conflict. Culture was evaluated through self-assessments of how independent or interdependent the subjects were (Markus & Kitayama, 1991, and conflict behavior through eight conflict management styles: dominating, integrating, compromising, avoiding, obliging, emotion, neglect and third-party help (Rahim, 1983; Ting-Toomey et al., 2000. Furthermore, drawing upon face-negotiation theory (Ting-Toomey, 1988; Ting-Toomey & Kurogi, 1998, a test was made of whether self-face, other-face and mutual-face concerns could explain cultural differences in conflict behavior. A total of 185 professionals from different countries completed an Internet questionnaire. An exploratory factor analysis of the eight styles revealed three factors which seem to describe direct, indirect and integrating plus compromising conflict behaviors. In line with this study's hypotheses, persons with a tendency to act independently mentioned direct styles, as well as integrating, and persons with a tendency to act interdependently mentioned indirect styles in addition to integrating and compromising. Furthermore, a concern for self-face maintenance was related to direct conflict behavior, a concern for other-face maintenance to indirect conflict behavior, and a concern for mutual-face maintenance to integrating and compromising. However, persons with a tendency to act independently do not seem to be particularly concerned about self-face maintenance. Persons with a tendency to act interdependently, on the other hand, show other- and mutual-face concerns in conflict situations. It was concluded that face concerns do play a crucial role, but mainly in explaining the conflict behavior of persons with a tendency to act interdependently

  13. Workforce ethnic diversity and culturally competent health care: the case of Arab physicians in Israel.

    Popper-Giveon, Ariela; Liberman, Ido; Keshet, Yael

    2014-01-01

    In recent years, a growing body of literature has been calling for ethnic diversity in health systems, especially in multicultural contexts. Ethnic diversity within the health care workforce is considered to play an important role in reducing health disparities among different ethnic groups. The present study explores the topic using quantitative data on participation of Arab employees in the Israeli health system and qualitative data collected through semi-structured interviews with Arab physicians working in the predominantly Jewish Israeli health system. We show that despite the underrepresentation of Arabs in the Israeli health system, Arab physicians who hold positions in Israeli hospitals do not perceive themselves as representatives of the Arab sector; moreover, they consider themselves as having broken through the 'glass ceiling' and reject stereotyping as Arab 'niche doctors.' We conclude that minority physicians may prefer to promote culturally competent health care through integration and advocacy of interaction with the different cultures represented in the population, rather than serving as representatives of their own ethnic minority population. These findings may concern various medical contexts in which issues of ethnic underrepresentation in the health system are relevant, as well as sociological contexts, especially those regarding minority populations and professions.

  14. How are we 'doing' cultural diversity? A look across English Canadian undergraduate medical school programmes.

    2010-01-01

    Cultural diversity education is a required curriculum component at all accredited North American medical schools. Each medical school determines its own content and pedagogical approaches. This preliminary study maps the approaches to cultural diversity education in English Canadian medical schools. A review of 14 English Canadian medical school websites was undertaken to identify the theoretical approaches to cultural diversity education. A PubMed search was also completed to identify the recent literature on cultural diversity medical education in Canada. Data were analysed using 10 criteria that distinguish pedagogical approaches, curricular structure, course content and theoretical understandings of cultural diversity. Based on the information posted on English Canadian medical school websites, all schools offer cultural diversity education although how each 'does' cultural diversity differs widely. Two medical schools have adopted the cultural competency model; five have adopted a critical cultural approach to diversity; and the remaining seven have incorporated some aspects of both approaches. More comprehensive research is needed to map the theoretical approaches to cultural diversity at Canadian medical schools and to evaluate the long-term effectiveness of these approaches on improving physician-patient relationships, reducing health disparities, improving health outcomes and producing positive learning outcomes in physicians.

    The recent recolonisation of the Central European lowland (CEL) by the grey wolf (Canis lupus) provides an excellent opportunity to study the effect of founder events on endoparasite diversity. Which role do prey and predator populations play in the re-establishment of endoparasite life cycles? Which intrinsic and extrinsic factors control individual endoparasite diversity in an expanding host population? In 53 individually known CEL wolves sampled in Germany, we revealed a community of four cestode, eight nematode, one trematode and 12 potential Sarcocystis species through molecular genetic techniques. Infections with zoonotic Echinococcus multilocularis, Trichinella britovi and T. spiralis occurred as single cases. Per capita endoparasite species richness and diversity significantly increased with population size and changed with age, whereas sex, microsatellite heterozygosity, and geographic origin had no effect. Tapeworm abundance (Taenia spp.) was significantly higher in immigrants than natives. Metacestode prevalence was slightly higher in ungulates from wolf territories than from control areas elsewhere. Even though alternative canid definitive hosts might also play a role within the investigated parasite life cycles, our findings indicate that (1) immigrated wolves increase parasite diversity in German packs, and (2) prevalence of wolf-associated parasites had declined during wolf absence and has now risen during recolonisation.

    Evolutionary theory predicts that natural selection will fashion cognitive biases to guide when, and from whom, individuals acquire social information, but the precise nature of these biases, especially in ecologically valid group contexts, remains unknown. We exposed four captive groups of chimpanzees (Pan troglodytes) to a novel extractive foraging device and, by fitting statistical models, isolated four simultaneously operating transmission biases. These include biases to copy (i) higher-ranking and (ii) expert individuals, and to copy others when (iii) uncertain or (iv) of low rank. High-ranking individuals were relatively un-strategic in their use of acquired knowledge, which, combined with the bias for others to observe them, may explain reports that high innovation rates (in juveniles and subordinates) do not generate a correspondingly high frequency of traditions in chimpanzees. Given the typically low rank of immigrants in chimpanzees, a 'copying dominants' bias may contribute to the observed maintenance of distinct cultural repertoires in neighboring communities despite sharing similar ecology and knowledgeable migrants. Thus, a copying dominants strategy may, as often proposed for conformist transmission, and perhaps in concert with it, restrict the accumulation of traditions within chimpanzee communities whilst maintaining cultural diversity.

  19. Diverse cultures and official laws: multiculturalism and Euroscepticism?

    Directory of Open Access Journals (Sweden)

    Esin Örücü

    2010-11-01

    Full Text Available Normative pluralism refers to a social fact: the co-existence of different bodies of norms within the same social space. State legal pluralism indicates a single overarching national legal system but plural laws, the state recognising different rules for specific categories of persons. However, the equating of multiculturalism and legal pluralism with state law is challenged. In the modern unitary nation state of the Western type only a weak version of legal pluralism in which state centralism still prevails is acceptable. Below it is advanced that in this state the accommodation of cultural diversity and multiple normative orders can only be brought about by the judge, the tuner or the navigator and steersman of the law, by using discretion and creative interpretation and not by the legislators, whose main demarcation lines are clearly drawn within domestic law by the Constitution, and within Europe and within the EU by the demands of human rights and 'ever closer integration'. In both of the critical illustrations below - the equality of the spouses in Turkish family law and the General Principles of the CEFL on divorce and maintenance - more scope should be given to judges to cope with and to create the necessary 'fit' between law and culture that do not coincide.

    Ideas of linking cultural diversity and knowledge resources have recently gained momentum. However, only little research has empirically addressed the issues of knowledge sharing in diverse organizations. This explorative article is based on an ethnographic fieldwork in a Danish organization......, and sets out to illustrate implications of knowledge sharing in diverse organizations. It is argued that the theories on management of cultural diversity should include theories on knowledge and knowledge sharing. The main theoretical argument is that a locally grounded understanding of social aspects...... of knowledge sharing should be the departure point for dealing with cultural diversity in a business context....

  1. Management strategies to harness cultural diversity in Australian construction sites - a social identity perspective

    Directory of Open Access Journals (Sweden)

    Martin Loosemore

    2012-02-01

    Full Text Available Construction sites around the world employ large numbers of people from diverse cultural backgrounds. The effective management of this cultural diversity has important implications for the productivity, safety, health and welfare of construction workers and for the performance and reputation of firms which employ them. The findings of a three year, multi-staged study of cultural diversity management practices on construction sites are critiqued using social identity theory. This reveals that so called “best-practice” diversity management strategies may have an opposite effect to that intended. It is concluded that the management of diversity on construction projects would benefit from being informed by social identity research.

  9. A recent bottleneck of Y chromosome diversity coincides with a global change in culture

    KAUST Repository

    2015-04-30

    It is commonly thought that human genetic diversity in non-African populations was shaped primarily by an out-of-Africa dispersal 50–100 thousand yr ago (kya). Here, we present a study of 456 geographically diverse high-coverage Y chromosome sequences, including 299 newly reported samples. Applying ancient DNA calibration, we date the Y-chromosomal most recent common ancestor (MRCA) in Africa at 254 (95% CI 192–307) kya and detect a cluster of major non-African founder haplogroups in a narrow time interval at 47–52 kya, consistent with a rapid initial colonization model of Eurasia and Oceania after the out-of-Africa bottleneck. In contrast to demographic reconstructions based on mtDNA, we infer a second strong bottleneck in Y-chromosome lineages dating to the last 10 ky. We hypothesize that this bottleneck is caused by cultural changes affecting variance of reproductive success among males.

  10. An efficient test for comparing sequence diversity between two populations.

    2001-01-01

    We address the problem of comparing interindividual genomic sequence diversity between two populations. Although the methods are general, for concreteness we focus on comparing two human immunodeficiency virus (HIV) infected populations. From a viral isolate(s) taken from each individual in a sample of persons from each population, suppose one or multiple measurements are made on the genetic sequence of a coding region of HIV. Given a definition of genetic distance between sequences, the goal is to test if the distribution of interindividual distances differs between populations. If distances between all pairs of sequences within each group are used, then data-dependencies arising from the use of multiple sequences from individuals invalidates the use of a standard two-sample test such as the t-test. Where this problem has been recognized, a typical solution has been to apply a standard test to a reduced dataset comprised of one sequence or a consensus sequence from each patient. Disadvantages of this procedure are that the conclusion of the test depends on the choice of utilized sequences, often an arbitrary decision, and exclusion of replicate sequences from the analysis may needlessly sacrifice statistical power. We present a new test free of these drawbacks, which is based on a statistic that linearly combines all possible standard test statistics calculated from independent sequence subsamples. We describe statistical power advantages of the test and illustrate its use by application to nucleotide sequence distances measured from HIV-1 infected populations in southern Africa (GenBank accession numbers AF110959--AF110981) and North America/Europe. The test makes minimal assumptions, is maximally efficient and objective, and is broadly applicable.

  11. Genomewide Mutational Diversity in Escherichia coli Population Evolving in Prolonged Stationary Phase.

    Prolonged stationary phase is an approximation of natural environments presenting a range of stresses. Survival in prolonged stationary phase requires alternative metabolic pathways for survival. This study describes the repertoire of mutations accumulating in starving Escherichia coli populations in lysogeny broth. A wide range of mutations accumulates over the course of 1 month in stationary phase. Single nucleotide polymorphisms (SNPs) constitute 64% of all mutations. A majority of these mutations are nonsynonymous and are located at conserved loci. There is an increase in genetic diversity in the evolving populations over time. Computer simulations of evolution in stationary phase suggest that the maximum frequency of mutations observed in our experimental populations cannot be explained by neutral drift. Moreover, there is frequent genetic parallelism across populations, suggesting that these mutations are under positive selection. Finally, functional analysis of mutations suggests that regulatory mutations are frequent targets of selection. IMPORTANCE Prolonged stationary phase in bacteria, contrary to its name, is highly dynamic, with extreme nutrient limitation as a predominant stress. Stationary-phase cultures adapt by rapidly selecting a mutation(s) that confers a growth advantage in stationary phase (GASP). The phenotypic diversity of starving E. coli populations has been studied in detail; however, only a few mutations that accumulate in prolonged stationary phase have been described. This study documented the spectrum of mutations appearing in Escherichia coli during 28 days of prolonged starvation. The genetic diversity of the population increases over time in stationary phase to an extent that cannot be explained by random, neutral drift. This suggests that prolonged stationary phase offers a great model system to study adaptive evolution by natural selection.

    The study of food choice, one of the most complex human traits, requires an integrated approach that takes into account environmental, socio-cultural and biological diversity. We recruited 183 volunteers from four geo-linguistic groups and highly diversified in terms of both genetic background and food habits from whom we collected genotypes and phenotypes tightly linked to taste perception. We confirmed previous genetic associations, in particular with stevioside perception, and noted significant differences in food consumption: in particular, broccoli, mustard and beer consumption scores were significantly higher (Adjusted P = 0.02, Adjusted P groups.

    This article outlines how the melting pot and salad bowl views of cultural diversity have influenced the cultural training of nutrition educators and other health professionals. It explores how these views are changing in reaction to the changing demographics and health disparities seen in the US today and how the cultural training of nutrition educators has not kept up with these changing views. Suggestions for how this cultural education could be modified include placing a greater emphasis on both the cultural self-awareness of nutrition educators and the sociopolitical historical factors that influence the cultural orientation of nutrition educators and their clients.

Due to the environmental deterioration and overfishing, the size of its population has decreased sharply. To rescue this species it is necessary to study its genetic structure and phylogeography and hereby obtain better understanding of the population. In this study, we determined the genetic diversity of cultured and wild Brachymystax lenok tsinlingensis populations by analyzing their mtDNA Cyt b and D-loop genes. The results showed that the average contents of A, T, C and G in D-loop were 31.9%, 31.6%, 20.8% and 15.7%, respectively. The contents of A+T (63.5%) were higher than those of C+G (36.5%). In the Cyt b gene, the average contents of A, T, C and G were 24.6%, 28.2%, 31.6%and 15.6%, respectively. The contents of A+T (52.8%) were also higher than those of G+C (47

    Many schools of nursing have implemented standardized testing using platforms such as those developed by Assessment Technologies Institute (ATI) to better prepare students for success on the National Council Licensure Examination for Registered Nurses® (NCLEX-RN). This study extends and replicates the research on standardized testing to predict first-time pass success in a diverse student population and across two prelicensure program types. The final sample consisted of 589 students who graduated between 2003 and 2009. Demographic data, as well as academic performance and scores on the ATI RN Comprehensive Predictor, were analyzed. The findings in this study indicate that scores on the ATI RN Comprehensive Predictor were positively, significantly associated with first-time pass success. Students in jeopardy of failing the NCLEX-RN on their first attempt can be identified prior to graduation and remediation efforts can be strengthened to improve their success.

    Full Text Available The objective of this study was to determine the intra- and intergenetic diversities of eight different goat populations in Turkey including Hair, Angora, Kilis, Yayladag, Shami, Honamli, Saanen, and Alpine. A total of 244 DNA samples were genotyped using 11 microsatellites loci. The genetic differentiation between breeds was considerable as a result of the statistically significant (P0.05. Heterozygosity values ranged between 0.62 and 0.73. According to the structure and assignment test, Angora and Yayladag goats were assigned to the breed they belong to, while other breeds were assigned to two or more different groups. Because this study for the first time presented genetic data on the Yayladag goat, results of structure analysis and assigned test suggest that further analyses are needed using additional and different molecular markers.

    The recruitment of asymptomatic volunteers has been identified as a critical factor that is delaying the development and validation of preventive therapies for Alzheimer disease (AD). Typical recruitment strategies involve the use of convenience samples or soliciting participation of older adults with a family history of AD from clinics and outreach efforts. However, high-risk groups, such as ethnic/racial minorities, are traditionally less likely to be recruited for AD prevention studies, thus limiting the ability to generalize findings for a significant proportion of the aging population. A community-engagement approach was used to create a registry of 2311 research-ready, healthy adult volunteers who reflect the ethnically diverse local community. Furthermore, the registry's actual commitment to research was examined, through demonstrated participation rates in a clinical study. The approach had varying levels of success in establishing a large, diverse pool of individuals who are interested in participating in pharmacological prevention trials and meet the criteria for primary prevention research trials designed to delay the onset of AD. Our efforts suggest that entry criteria for the clinical trials need to be carefully considered to be inclusive of African Americans, and that sustained effort is needed to engage African Americans in pharmacological prevention approaches.

The Brahman, Lang Son, Ha Giang and U Dau Riu cattle were assigned to independent clusters while Nghe An, Thanh Hoa and Phu Yen cattle were grouped in a single cluster. We conclude that Vietnamese indigenous cattle have high levels...... of genetic diversity and distinct genetic structures. Based on these results, we recommend that for conservation homogenous populations (Nghe An, Thanh Hoa and Phu Yen) can be grouped to reduce costs and U Dau Riu, Lang Son and Ha Giang populations should be conserved separately to avoid loss of genetic...

    Full Text Available Abstract Background N-acetyltransferase type 2 (Nat2 is a phase II drug- metabolizing enzyme that plays a key role in the bioactivation of aromatic and heterocyclic amines. Its relevance in drug metabolism and disease susceptibility remains a central theme for pharmacogenetic research, mainly because of its genetic variability among human populations. In fact, the evolutionary and ethnic-specific SNPs on the NAT2 gene remain a focus for the potential discoveries in personalized drug therapy and genetic markers of diseases. Despite the wide characterization of NAT2 SNPs frequency in established ethnic groups, little data are available for highly admixed populations. In this context, five common NAT2 SNPs (G191A, C481T, G590A, A803G and G857A were investigated in a highly admixed population comprised of Afro-Brazilians, Whites, and Amerindians in northeastern Brazil. Thus, we sought to determine whether the distribution of NAT2 polymorphism is different among these three ethnic groups. Results Overall, there were no statistically significant differences in the distribution of NAT2 polymorphism when Afro-Brazilian and White groups were compared. Even the allele frequency of 191A, relatively common in African descendents, was not different between the Afro-Brazilian and White groups. However, allele and genotype frequencies of G590A were significantly higher in the Amerindian group than either in the Afro-Brazilian or White groups. Interestingly, a haplotype block between G590A and A803G was verified exclusively among Amerindians. Conclusions Our results indicate that ethnic admixture might contribute to a particular pattern of genetic diversity in the NAT2 gene and also offer new insights for the investigation of possible new NAT2 gene-environment effects in admixed populations.

    Cultural diversity among patients presents specific challenges to physicians. Therefore, cultural diversity training is needed in medical education. In cases where strategic curriculum documents form the basis of medical training it is expected that the topic of cultural diversity is included in these documents, especially if these have been recently updated. The aim of this study was to assess the current formal status of cultural diversity training in the Netherlands, which is a multi-ethnic country with recently updated medical curriculum documents. In February and March 2013, a document analysis was performed of strategic curriculum documents for undergraduate and postgraduate medical education in the Netherlands. All text phrases that referred to cultural diversity were extracted from these documents. Subsequently, these phrases were sorted into objectives, training methods or evaluation tools to assess how they contributed to adequate curriculum design. Of a total of 52 documents, 33 documents contained phrases with information about cultural diversity training. Cultural diversity aspects were more prominently described in the curriculum documents for undergraduate education than in those for postgraduate education. The most specific information about cultural diversity was found in the blueprint for undergraduate medical education. In the postgraduate curriculum documents, attention to cultural diversity differed among specialties and was mainly superficial. Cultural diversity is an underrepresented topic in the Dutch documents that form the basis for actual medical training, although the documents have been updated recently. Attention to the topic is thus unwarranted. This situation does not fit the demand of a multi-ethnic society for doctors with cultural diversity competences. Multi-ethnic countries should be critical on the content of the bases for their medical educational curricula.

    Due to the highly restricted species-tropism of Hepatitis C virus (HCV) a limited number of animal models exist for pre-clinical evaluation of vaccines and antiviral compounds. The human-liver chimeric mouse model allows heterologous challenge with clinically relevant strains derived from patients. However, to date, the transmission and longitudinal evolution of founder viral populations in this model have not been characterized in-depth using state-of-the-art sequencing technologies. Focusing on NS3 protease encoding region of the viral genome, mutant spectra in a donor inoculum and individual recipient mice were determined via Illumina sequencing and compared, to determine the effects of transmission on founder viral population complexity. In all transmissions, a genetic bottleneck was observed, although diverse viral populations were transmitted in each case. A low frequency cloud of mutations ( 1% restricted to a subset of nucleotides. The population of SNVs >1% was reduced upon transmission while the low frequency SNV cloud remained stable. Fixation of multiple identical synonymous substitutions was apparent in independent transmissions, and no evidence for reversion of T-cell epitopes was observed. In addition, susceptibility of founder populations to antiviral therapy was assessed. Animals were treated with protease inhibitor (PI) monotherapy to track resistance associated substitution (RAS) emergence. Longitudinal analyses revealed a decline in population diversity under therapy, with no detectable RAS >1% prior to therapy commencement. Despite inoculation from a common source and identical therapeutic regimens, unique RAS emergence profiles were identified in different hosts prior to and during therapeutic failure, with complex mutational signatures at protease residues 155, 156 and 168 detected. Together these analyses track viral population complexity at high-resolution in the human-liver chimeric mouse model post-transmission and under therapeutic

    Molecular and cultivation approaches were employed to study the phylogenetic richness and temporal dynamics of Streptococcus and Veillonella populations in the small intestine. Microbial profiling of human small intestinal samples collected from four ileostomy subjects at four time points displayed abundant populations of Streptococcus spp. most affiliated with S. salivarius, S. thermophilus, and S. parasanguinis, as well as Veillonella spp. affiliated with V. atypica, V. parvula, V. dispar, and V. rogosae. Relative abundances varied per subject and time of sampling. Streptococcus and Veillonella isolates were cultured using selective media from ileostoma effluent samples collected at two time points from a single subject. The richness of the Streptococcus and Veillonella isolates was assessed at species and strain level by 16S rRNA gene sequencing and genetic fingerprinting, respectively. A total of 160 Streptococcus and 37 Veillonella isolates were obtained. Genetic fingerprinting differentiated seven Streptococcus lineages from ileostoma effluent, illustrating the strain richness within this ecosystem. The Veillonella isolates were represented by a single phylotype. Our study demonstrated that the small intestinal Streptococcus populations displayed considerable changes over time at the genetic lineage level because only representative strains of a single Streptococcus lineage could be cultivated from ileostoma effluent at both time points.

    As American society becomes increasingly diverse, and the nursing profession does not, there has been a focus on promoting both cultural competence and diversity within the profession. Although culture and diversity are widely discussed in nursing education, the issue of racism may be avoided or suppressed. Institutionalized racism within nursing education must be acknowledged and discussed before nursing education may be transformed. Madeleine Leininger's Culture Care Theory is an established nursing theory that emphasizes culture and care as essential concepts in nursing. Theoretical frameworks abound in nursing, and Culture Care Theory may be underutilized and misunderstood within nursing education. This article examines the issue of racism in nursing education and recommends Culture Care Theory as a relevant framework for enhancing both cultural competence and diversity.

    Full Text Available Leishmania infantum (syn. Leishmania chagasi is the etiological agent of visceral leishmaniasis (VL in Brazil. The epidemiology of VL is poorly understood. Therefore, a more detailed molecular characterization at an intraspecific level is certainly needed. Herein, three independent molecular methods, multilocus microsatellite typing (MLMT, random amplification of polymorphic DNA (RAPD and simple sequence repeats-polymerase chain reaction (SSR-PCR, were used to evaluate the genetic diversity of 53 L. infantum isolates from five different endemic areas in Brazil. Population structures were inferred by distance-based and Bayesian-based approaches. Eighteen very similar genotypes were detected by MLMT, most of them differed in only one locus and no correlation was found between MLMT profiles, geographical origin or the estimated population structure. However, complex profiles composed of 182 bands obtained by both RAPD and SSR-PCR assays gave different results. Unweighted pair group method with arithmetic mean trees built from these data revealed a high degree of homogeneity within isolates of L. infantum. Interestingly, despite this genetic homogeneity, most of the isolates clustered according to their geographical origin.

    Genetic polymorphism along mitochondrial DNA (mtDNA) defines population-specific signatures called mtDNA haplogroups. Estimation of mtDNA haplogroup distribution may be prone to errors, notably if the study sample is not drawn from a multicenter cohort. Here, we report on mtDNA diversity in a sample of African American individuals (n = 343) enrolled in a multicenter cohort. Sequencing of the hypervariable regions I and II of the D-loop control region showed that the most common mitochondrial variants are 73G, 146C, 150T, 152C, 189G, 16278T, and 16311C. In agreement with the published data, we observed 17 common mtDNA haplogroups: L0, L1, L1b, L1c, L2, L2a, L2b, L2c, L2e, L3, L3b, L3d, L3e, L3f, L3h, L3x, and L4. The most commonly observed haplogroup is L2a (19.8%), followed by L1b (10.2%). Overall, the observed mtDNA haplogroup distribution in our study is similar to those published for the African American and the African populations.

  8. Explaining the Linguistic Diversity of Sahul Using Population Models

    The region of the ancient Sahul continent (present day Australia and New Guinea, and surrounding islands) is home to extreme linguistic diversity. Even apart from the huge Austronesian language family, which spread into the area after the breakup of the Sahul continent in the Holocene, there are hundreds of languages from many apparently unrelated families. On each of the subcontinents, the generally accepted classification recognizes one large, widespread family and a number of unrelatable smaller families. If these language families are related to each other, it is at a depth which is inaccessible to standard linguistic methods. We have inferred the history of structural characteristics of these languages under an admixture model, using a Bayesian algorithm originally developed to discover populations on the basis of recombining genetic markers. This analysis identifies 10 ancestral language populations, some of which can be identified with clearly defined phylogenetic groups. The results also show traces of early dispersals, including hints at ancient connections between Australian languages and some Papuan groups (long hypothesized, never before demonstrated). Systematic language contact effects between members of big phylogenetic groups are also detected, which can in some cases be identified with a diffusional or substrate signal. Most interestingly, however, there remains striking evidence of a phylogenetic signal, with many languages showing negligible amounts of admixture. PMID:19918360

    The role of cultural diversities in doctor's everyday work is going more and more important in globalised world, therefore it draws lots of attention in literature. Cultural differences that exist between people, such as language, dress and traditions, are usually distinguished from the term cultural diversity which is mainly understood as having different cultures respect each other's differences. The great effort is made to educate culturally competent practitioners, nurses or doctors. The presented case of lady from Janjevo was a good role model for work with all patients with culturally different background coming to family practice. This lady example could also help to other colleagues to learn from experience on systematic way.

  17. Enhancing pediatric workforce diversity and providing culturally effective pediatric care: implications for practice, education, and policy making.

    Science.gov (United States)

    2013-10-01

    This policy statement serves to combine and update 2 previously independent but overlapping statements from the American Academy of Pediatrics (AAP) on culturally effective health care (CEHC) and workforce diversity. The AAP has long recognized that with the ever-increasing diversity of the pediatric population in the United States, the health of all children depends on the ability of all pediatricians to practice culturally effective care. CEHC can be defined as the delivery of care within the context of appropriate physician knowledge, understanding, and appreciation of all cultural distinctions, leading to optimal health outcomes. The AAP believes that CEHC is a critical social value and that the knowledge and skills necessary for providing CEHC can be taught and acquired through focused curricula across the spectrum of lifelong learning. This statement also addresses workforce diversity, health disparities, and affirmative action. The discussion of diversity is broadened to include not only race, ethnicity, and language but also cultural attributes such as gender, religious beliefs, sexual orientation, and disability, which may affect the quality of health care. The AAP believes that efforts must be supported through health policy and advocacy initiatives to promote the delivery of CEHC and to overcome educational, organizational, and other barriers to improving workforce diversity.

  18. Population change and socio-cultural values.

    Science.gov (United States)

    1982-06-01

    The developing countries of the world in general, and those of Asia and the Pacific in particular, recognize that unplanned population growth is a stumbling block to socioeconomic development. Discussion here focuses on population growth and social, economic, and institutional forces, which are referred to as sociocultural values. Generally, sociocultural values change sluggishly over time. The rate at which a country's sociocultural values change depends on several factors such as the stage of economic development and modernization and whether a country has an open or closed door policy. "The Value of Children Study: A Crossnational Study" by Fred Arnold et al. shows that there are positive and negative values attributed to children in the Asian countries. These are: positive general values--emotional benefits, economic benefits and security, self enrichment and development, identification with children, and family cohesiveness and continuity; negative general values--emotional costs, economic costs, restrictions on opportunity costs, physical demands, and family costs; large family values--sibling relationships, sex preferences, child survival; and small family values--maternal health and societal costs. Possibly the most formidable obstacle to the success of antinatalist population policies is that of religious values. It appears that the Muslim world is divided on the issue of fertility control. Conflicting views regarding fertility control is perhaps aggravated by the fact that there is no central international religious official hierarchy that issues out edicts. Despite the presence of a centralized religious hierarchy and a network of churches from the Vatican to the village levels among the Catholics, and a clearer elucidation of the Humanae Vitae, a liberal attitude to population regulation and family planning has emerged, largely because of the declining quality of life of the people resulting from unplanned births. Economic benefits of children include

    The genetic diversity and structure of long-tailed macaques (Macaca fascicularis) in Peninsular Malaysia, a widely used non-human primate species in biomedical research, have not been thoroughly characterized. Thirteen sites of wild populations of long-tailed macaques representing six states were sampled and analyzed with 18 STR markers. The Sunggala and Penang Island populations showed the highest genetic diversity estimates, while the Jerejak Island population was the most genetically discrete due to isolation from the mainland shelf. Concordant with pairwise F(st) estimates, STRUCTURE analyses of the seven PCA-correlated clusters revealed low to moderate differentiation among the sampling sites. No association between geographic and genetic distances exists, suggesting that the study sites, including island study sites, are genetically if not geographically contiguous. The status of the genetic structure and composition of long-tailed macaque populations require further scrutiny to develop this species as an important animal model in biomedical research. © 2014 John Wiley & Sons A/S.

    2010-05-01

    In this paper we present the current state of cultural diversity education for undergraduate medical students in three English-speaking countries: the United Kingdom (U.K.), United States (U.S.) and Canada. We review key documents that have shaped cultural diversity education in each country and compare and contrast current issues. It is beyond the scope of this paper to discuss the varied terminology that is immediately evident. Suffice it to say that there are many terms (e.g. cultural awareness, competence, sensitivity, sensibility, diversity and critical cultural diversity) used in different contexts with different meanings. The major issues that all three countries face include a lack of conceptual clarity, and fragmented and variable programs to teach cultural diversity. Faculty and staff support and development, and ambivalence from both staff and students continue to be a challenge. We suggest that greater international collaboration may help provide some solutions.

    Concepts of culture and diversity are necessary considerations in the scientific application of theory generation and developmental processes of preventive interventions; yet, culture and/or diversity are often overlooked until later stages (e.g., adaptation [T3] and dissemination [T4]) of the translational science process. Here, we present a conceptual framework focused on the seamless incorporation of culture and diversity throughout the various stages of the translational science process (T1-T5). Informed by a community-engaged research approach, this framework guides integration of cultural and diversity considerations at each phase with emphasis on the importance and value of "citizen scientists" being research partners to promote ecological validity. The integrated partnership covers the first phase of intervention development through final phases that ultimately facilitate more global, universal translation of changes in attitudes, norms, and systems. Our comprehensive model for incorporating culture and diversity into translational research provides a basis for further discussion and translational science development.

    In contemporary debates about the nature of bioethics there is a widespread view that bioethical decision making should involve certain knowledge of and respect for cultural diversity of persons to be affected. The aim of this article is to show that this view is untenable and misleading. It is argued that introducing the idea of respect for cultural diversity into bioethics encounters a series of conceptual and empirical constraints. While acknowledging that cultural diversity is something that decision makers in bioethical contexts should try to understand and, when possible, respect, it is argued that this cultural turn ignores the typically normative role of bioethics and thus threatens to undermine its very foundations.

  3. What sustains cultural diversity and what undermines it? Axelrod and beyond

    We relax a simplification of Axelrod's (1997) model of cultural dissemination that has not yet been studied, the assumption that all cultural states are nominal. We integrate metric states into the original model. Computational experiments demonstrate that metric states undermine cultural diversity, even without noise, by creating sufficient overlap between agents for mutual influence. We then show how adding "bounded confidence" - a recent innovation in models of social influence - allows cultural diversity to persist. However, further experiments reveal that the solution is fragile. Diversity can be sustained only with a relatively small number of metric states, low levels of noise or narrow confidence intervals.

    The mass release of hatchery-propagated stocks raises numerous questions concerning its efficiency in terms of local recruitment and effect on the genetic diversity of wild populations. A seeding program, consisting of mass release of hatchery-produced juveniles in the local naturally occurring population of great scallops (Pecten maximus L.), was initiated in the early 1980s in the Bay of Brest (France). The present study aims at evaluating whether this seeding program leads to actual population enhancement, with detectable effects on genetic diversity and effective population size, or consists of sea ranching with limited genetic consequences on the wild stock. To address this question, microsatellite-based genetic monitoring of three hatchery-born and naturally recruited populations was conducted over a 5-year period. Results showed a limited reduction in allelic richness but a strong alteration of allelic frequencies in hatchery populations, while genetic diversity appeared very stable over time in the wild populations. A temporal increase in relatedness was observed in both cultured stock and wild populations. Effective population size (Ne) estimates were low and variable in the wild population. Moreover, the application of the Ryman-Laikre model suggested a high contribution of hatchery-born scallops to the reproductive output of the wild population. Overall, the data suggest that the main objective of the seeding program, which is stock enhancement, is fulfilled. Moreover, gene flow from surrounding populations and/or the reproductive input of undetected sub-populations within the bay may buffer the Ryman-Laikre effect and ensure the retention of the local genetic variability.

    Full Text Available From the foods we eat and the houses we construct, to our religious practices and political organization, to who we can marry and the types of games we teach our children, the diversity of cultural practices in the world is astounding. Yet, our ability to visualize and understand this diversity is limited by the ways it has been documented and shared: on a culture-by-culture basis, in locally-told stories or difficult-to-access repositories. In this paper we introduce D-PLACE, the Database of Places, Language, Culture, and Environment. This expandable and open-access database (accessible at https://d-place.org brings together a dispersed corpus of information on the geography, language, culture, and environment of over 1400 human societies. We aim to enable researchers to investigate the extent to which patterns in cultural diversity are shaped by different forces, including shared history, demographics, migration/diffusion, cultural innovations, and environmental and ecological conditions. We detail how D-PLACE helps to overcome four common barriers to understanding these forces: i location of relevant cultural data, (ii linking data from distinct sources using diverse ethnonyms, (iii variable time and place foci for data, and (iv spatial and historical dependencies among cultural groups that present challenges for analysis. D-PLACE facilitates the visualisation of relationships among cultural groups and between people and their environments, with results downloadable as tables, on a map, or on a linguistic tree. We also describe how D-PLACE can be used for exploratory, predictive, and evolutionary analyses of cultural diversity by a range of users, from members of the worldwide public interested in contrasting their own cultural practices with those of other societies, to researchers using large-scale computational phylogenetic analyses to study cultural evolution.

    Full Text Available We analyzed culturable endophytic bacteria from Moso bamboo (Phyllostachys edulis using traditional bacterial isolation and culture methods and then studied the colony characteristics and diversity with a 16S rDNA sequence analysis. We isolated 82 endophytic bacteria strains belonging to 47 species in 26 genera from the root, rhizome, stem and leaves of Moso bamboo species from populations on Wuyi Mountain, and in the Jiangle and Changting regions. There were significant differences in the composition of the culturable endophytic bacteria isolated from the different areas and from different tissues. The dominant bacteria strains from the Wuyi Mountain samples were Arthrobacter, Staphylococcus, Bacillus and Enterobacter, while the dominant bacteria from the Jiangle samples were Bacillus, Staphylococcus and Curtobacterium, and the dominant bacteria in the Changting samples were Alcaligenes, Pseudomonas, Staphylococcus and Bacillus. Our results demonstrate the abundant diversity of endophytic bacteria in Moso bamboo.

    For many years, studies have identified a need for greater racial and ethnic diversity among dental professionals. However, the ability of the field to collectively address the problem has been hindered by the low numbers of underrepresented minority students who apply to dental school. Over the past two decades, college attendance rates have increased and U.S. dental school applications have tripled, but the number of underrepresented minority dental applicants has remained about the same. With the increasing diversity of the U.S. population and specifically that of the state of California, the dental workforce would be enhanced by the presence of more underrepresented minority dentists. Additionally, curricular changes should be implemented to better prepare dental students to meet the oral health care needs of diverse populations. There is general agreement that these workforce and curricular changes would enhance access to care for underserved populations. For seven years, Loma Linda University School of Dentistry participated in the Pipeline, Profession, and Practice: Community-Based Dental Education program. The first phase of this national program addressed deficiencies in diversity in dentistry and in access to oral health care. In the second phase, Loma Linda University continued to collaborate with other California dental schools on specific state initiatives. This article provides an overview of the school's efforts to enroll a more diverse student body, enhance all its students' cultural competence, and expand care to underserved populations.

  13. Preparing Science Teachers for Culturally Diverse Students: Developing Cultural Literacy Through Cultural Immersion, Cultural Translators and Communities of Practice

    2006-09-01

    This three year study of P-12 professional development is grounded in sociocultural theories that hold that building knowledge and relationships among individuals from different cultural backgrounds entails joint activity toward common goals and cultural dialogues mediated by cultural translators. Sixty P-12 pre and in-service teachers in a year long interdisciplinary science curriculum course shared the goal of developing culturally relevant, standards-based science curricula for Native Hawai'ian students. Teachers and Native Hawai'ian instructors lived and worked together during a five day culture-science immersion in rural school and community sites and met several times at school, university, and community sites to build knowledge and share programs. Teachers were deeply moved by immersion experiences, learned to connect cultural understandings, e.g., a Hawai'ian sense of place and curriculum development, and highly valued collaborating with peers on curriculum development and implementation. The study finds that long term professional development providing situated learning through cultural immersion, cultural translators, and interdisciplinary instruction supports the establishment of communities of practice in which participants develop the cross-cultural knowledge and literacy needed for the development of locally relevant, place and standards-based curricula and pedagogy.

    The meaningful consideration of cultural practices, values and beliefs is a necessary component in the effective translation of advancements in neuroscience to clinical practice and public discourse. Society's immense investment in biomedical science and technology, in conjunction with an increasingly diverse socio-cultural landscape, necessitates the study of how potential discoveries in neurodegenerative diseases such as Alzheimer disease are perceived and utilized across cultures. Building on the work of neuroscientists, ethicists and philosophers, we argue that the growing field of neuroethics provides a pragmatic and constructive pathway to guide advancements in neuroscience in a manner that is culturally nuanced and relevant. Here we review a case study of one issue in culturally oriented neuroscience research where it is evident that traditional research ethics must be broadened and the values and needs of diverse populations considered for meaningful and relevant research practices. A global approach to neuroethics has the potential to furnish critical engagement with cultural considerations of advancements in neuroscience.

    There is considerable ambiguity in the subjective dimensions that comprise much of the relational dynamic of the clinical encounter. Comfort with this ambiguity, and recognition of the potential uncertainty of particular domains of medicine (e.g.--cultural factors of illness expression, value bias in diagnoses, etc) is an important facet of medical education. This paper begins by defining ambiguity and uncertainty as relevant to clinical practice. Studies have shown differing patterns of students' tolerance for ambiguity and uncertainty that appear to reflect extant attitudinal predispositions toward technology, objectivity, culture, value- and theory-ladeness, and the need for self-examination. This paper reports on those findings specifically related to the theme of uncertainty as relevant to teaching about cultural diversity. Its focus is to identify how and where the theme of certainty arose in the teaching and learning of cultural diversity, what were the attitudes toward this theme and topic, and how these attitudes and responses reflect and inform this area of medical pedagogy. A semi-structured interview was undertaken with 61 stakeholders (including policymakers, diversity teachers, students and users). The data were analysed and themes identified. There were diverse views about what the term cultural diversity means and what should constitute the cultural diversity curriculum. There was a need to provide certainty in teaching cultural diversity with diversity teachers feeling under considerable pressure to provide information. Students discomfort with uncertainty was felt to drive cultural diversity teaching towards factual emphasis rather than reflection or taking a patient centred approach. Students and faculty may feel that cultural diversity teaching is more about how to avoid professional, medico-legal pitfalls, rather than improving the patient experience or the patient-physician relationship. There may be pressure to imbue cultural diversity issues

    A common misconception is that the phrase workplace diversity means meeting certain quotas in employee race or gender categories. In fact, diversity is much more than that. This article explores the unique benefits and challenges of managing a culturally diverse medical practice team and offers practice managers 25 practical strategies. It describes the two types of diversity training that are beneficial to practice managers and the kinds of policies, practices, and procedures that foster and promote diversity. This article also explores ethnocentrism, racism, ageism, sexism, stereotyping, and other potentially divisive issues among a diverse medical practice team. It provides an assessment instrument practice managers can use to evaluate their own diversity management skills. Finally, this article defines specifically what is meant by the term diversity and explores the top 10 diversity issues in workplaces today.

    Background Interpopulation differences in drug responses are well documented, and in some cases they correspond to differences in the frequency of associated genetic markers. Understanding the diversity of genetic markers associated with drug response across different global populations is essential to infer population rates of drug response or risk for adverse drug reactions, and to guide implementation of pharmacogenomic testing. Sri Lanka is a culturally and linguistically diverse nation, but little is known about the population genetics of the major Sri Lankan ethnic groups. The objective of this study was to investigate the diversity of pharmacogenomic variants in the major Sri Lankan ethnic groups. Methods We examined the allelic diversity of more than 7000 variants in genes involved in drug biotransformation and response in the three major ethnic populations of Sri Lanka (Sinhalese, Sri Lankan Tamils, and Moors), and compared them with other South Asian, South East Asian, and European populations using Wright’s Fixation Index, principal component analysis, and STRUCTURE analysis. Results We observed overall high levels of similarity within the Sri Lankan populations (median FST=0.0034), and between Sri Lankan and other South Asian populations (median FST=0.0064). Notably, we observed substantial differentiation between Sri Lankan and European populations for important pharmacogenomic variants related to warfarin (VKORC1 rs9923231) and clopidogrel (CYP2C19 rs4986893) response. Conclusion These data expand our understanding of the population structure of Sri Lanka, provide a resource for pharmacogenomic research, and have implications for the clinical use of genetic testing of pharmacogenomic variants in these populations.

    Adapting evidence-based interventions to be more accessible and culturally sensitive to the needs of diverse populations is a potential strategy to address disparities in mental health care. We adapted an evidence-based depression-treatment strategy, Problem-Solving Treatment, to prevent depression among low-income mothers with vulnerable children. Intervention adaptations spanned 3 domains: (1) the intervention's new prevention focus, (2) conducting a parent-focused intervention in venues oriented to children; and (3) cultural competency. The feasibility of adaptations was assessed through 2 pilot-randomized trials (n = 93), which demonstrated high participant adherence, satisfaction, and retention, demonstrating the feasibility of our adaptations.

  16. Population policies and cultural values: a Mexican editorial.

    Science.gov (United States)

    1978-01-01

    A new population policy for Mexico, based on the need to regulate demographic growth, should be developed without damaging the cultural values of the Mexican people. The role of cultural values in the identification of demographic problems, formulation of population policies, and implementation of programs, was studied in Mexico under sponsorship of the U.N. Population Fund. Population policies should be understood as a creative response to problems that life poses. Problems, policies, and national programs often originate with the elite or the middle class and are imposed with little respect for the real sense of the popular culture of the lower classes. It is an error to identify the traditional or folk values with a pronatalist attitude, because pronatalist attitudes can change when the people comprehend that birth control will aid in their fight for survival. The improvement of life for the Mexican peasant, proletarian and subproletarian is related to the modification of reproductive and migratory behavior. It is therefore an error to depict the new population policies as an interest of the upper classes and the imperialist countries. Population programs should be conceived and implemented by taking into account the values and aspirations of the popular majority.

    The Environmental Impact Assessment (EIA) Act of 1992 aimed to make the environment a central theme in development in Nigeria. Nevertheless, the extent of engagement with local cultures in the Nigerian EIA process is not statutorily guaranteed. While most EIAs in Nigeria have been for oil and gas projects in the Niger Delta, and have focused strongly on the biophysical environment, socio-economic and cultural aspects have remained marginal. The palpable neglect of community perceptions and cultural diversity in social impact assessment (SIA) in this region prone to conflict has tended to alienate the people in the decision-making process. Thus, despite claims to compliance with regulatory requirements for EIAs, and numerous purported sustainable development initiatives by international oil companies (IOCs), the region continues to face multiple sustainability challenges. This paper situates local perceptions and cultural diversity in participatory development and canvasses the integration of community perceptions and cultural diversity into SIA in the Niger Delta region. It is argued that doing this would be critical to ensuring acceptance and success of development actions within the context of local culture while also contributing to sustainable development policy in the region. - Highlights: • Nigeria EIA Act aimed to make the environment central to development in Nigeria. • Engagement with local communities in the process is not statutorily guaranteed. • SIAs in Nigeria neglect community perceptions and cultural diversity. • Article canvasses integrating community perceptions and cultural diversity in SIA. • Local acceptance in context of culture would yield sustainable development outcomes.

    This prospective cohort study evaluates colonization dynamics and molecular characteristics of methicillin-susceptible and - resistant Staphylococcus aureus (MSSA/MRSA) in a German general population. Nasal swabs of 1878 non-hospitalized adults were screened for S. aureus. Participants were screened thrice in intervals of 6-8 months. Isolates were characterized by spa and agr typing, mecA and mecC possession, respectively, and PCRs targeting virulence factors. 40.9% of all participants carried S. aureus at least once while 0.7% of the participants carried MRSA (mainly spa t011). MSSA isolates (n=1359) were associated with 331 different spa types; t084 (7.7%), t091 (6.1%) and t012 (71, 5.2%) were predominant. Of 206 participants carrying S. aureus at all three sampling time points, 14.1% carried the same spa type continuously; 5.3% carried different spa types with similar repeat patterns, but 80.6% carried S. aureus with unrelated spa types. MSSA isolates frequently harboured genes encoding enterotoxins (sec: 16.6%, seg: 63.1%, sei: 64.5%) and toxic shock syndrome toxin (tst: 17.5%), but rarely Panton-Valentine leukocidin (lukS-PV/lukF-PV: 0.2%). MSSA colonizing human nares in the community are clonally highly diverse. Among those constantly carrying S. aureus, clonal lineages changed over time. The proportion of persistent S. aureus carriers was lower than reported elsewhere. Copyright © 2016 Elsevier GmbH. All rights reserved.

    2011-01-01

    The New York State Medicaid Prescriber Education Program (PEP) is a partnership between the Department of Health and state academic institutions that provides prescribers with an evidence-based, noncommercial source of the latest objective information about pharmaceuticals. This article, detailing treatment of uncomplicated hypertension in diverse populations, represents one of the first large-scale PEP initiatives. The main risk factors for hypertension are age and obesity. Disparities in hypertension risk and outcomes among diverse populations are now believed to be more a function of personal habits, socioeconomic status and psychosocial factors rather than race, ethnicity, or genetics. Blood pressure is controllable in most patients, and all patients should be treated according to best practices. Lifestyle modification, especially diet and exercise, should be encouraged, but most patients will require more than one antihypertensive medication to control blood pressure. Combination therapy with an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker plus thiazide-type diuretic or dihydropyridine calcium channel blocker is largely universal in efficacy. Improved provider-patient partnership and communication is important to blood pressure lowering success, and cultural sensitivity should be taken into account where applicable.

    Selection of suitable genotypes from diverse seed banks may help phytoplankton populations to cope with environmental changes. This study examines whether the high genotypic diversity found in the Baltic cyst pool of the toxic dinoflagellate Alexandrium ostenfeldii is coupled to phenotypic variability that could aid short-term adaptation. Growth rates, cellular toxicities and bioluminescence of 34 genetically different clones isolated from cyst beds of four Baltic bloom sites were determined in batch culture experiments along temperature and salinity gradients covering present and future conditions in the Baltic Sea. For all parameters a significant effect of genotype on the response to temperature and salinity changes was identified. General or site-specific effects of the two factors remained minor. Clones thriving at future conditions were different from the best performing at present conditions, suggesting that genotypic shifts may be expected in the future. Increased proportions of highly potent saxitoxin were observed as a plastic response to temperature increase, indicating a potential for higher toxicity of future blooms. The observed standing variation in Baltic seed banks of A. ostenfeldii suggests that the population is likely to persist under environmental change.

    In South Africa, the estimate of HIV-infected population was 300,000 in September 1993, with 500 new infections occurring daily, mostly in poor neighborhoods with illiteracy rates of 25-50%. The AIDS Education and Training (AET) targeted low-literate groups by developing an educational package for the workplace. The methodology included repetition of key messages, stories from their own culture with pictures, interaction in groups, and visual aids to retain information. The content involved biomedical aspects of HIV/AIDS, testing and counseling, safe sex, traditional healers, the needs of the infected, and workplace/community issues. The pictures depicted men and women of all racial varieties to drive home the message that the infection can infect everybody. 31 colorful laminated posters were developed for the AIDS flip chart kit, and over 100 flip chart sessions were conducted at workplaces. An evaluation of the flip chart sessions queried 143 English- and 897 Tswana-speaking people at one company. 58% of respondents considered condom use and reducing the number of partners the most important message. 28% deemed biomedical facts and latency of the infection important, 25% the deadly nature of the disease, and 15% the modes of transmission. 44% desired to learn about prevention and 30% appreciated the interactive method of learning. All participants sought more information on STDs, where to get an HIV test, and how to have safer sex. AET provides assistance to clients to become educators themselves by means of policy development, refresher courses for educators, and action planning (condom distribution, STD control, referral for testing, and follow-up). The flip chart is also used for other health and lifestyle education regarding family planning, tuberculosis, sexuality, and communication skills aimed at company managers, union officials, and supervisors.

    The association between allelic diversity and ecogeographical variables was studied in natural populations of wild emmer wheat [Triticum turgidum ssp. dicoccoides (Körn.) Thell.], the tetraploid progenitor of cultivated wheat. Patterns of allelic diversity in 54 microsatellite loci were analyzed in a collection of 145 wild emmer wheat accessions representing 25 populations that were sampled across naturally occurring aridity gradient in Israel and surrounding regions. The obtained results revealed that 56% of the genetic variation resided among accessions within populations, while only 44% of the variation resided between populations. An unweighted pair-group method analysis (UPGMA) tree constructed based on the microsatellite allelic diversity divided the 25 populations into six major groups. Several groups were comprised of populations that were collected in ecologically similar but geographically remote habitats. Furthermore, genetic differentiation between populations was independent of the geographical distances. An interesting evolutionary phenomenon is highlighted by the unimodal relationship between allelic diversity and annual rainfall (r = 0.74, P < 0.0002), indicating higher allelic diversity in populations originated from habitats with intermediate environmental stress (i.e. rainfall 350-550 mm year(-1)). These results show for the first time that the 'intermediate-disturbance hypothesis', explaining biological diversity at the ecosystem level, also dominates the genetic diversity within a single species, the lowest hierarchical element of the biological diversity.

    Understanding population size and genetic diversity is critical for effective conservation of endangered species. The Amur tiger (Panthera tigris altaica) is the largest felid and a flagship species for wildlife conservation. Due to habitat loss and human activities, available habitat and population size are continuously shrinking. However, little is known about the true population size and genetic diversity of wild tiger populations in China. In this study, we collected 55 fecal samples and 1 hair sample to investigate the population size and genetic diversity of wild Amur tigers in Hunchun National Nature Reserve, Jilin Province, China. From the samples, we determined that 23 fecal samples and 1 hair sample were from 7 Amur tigers: 2 males, 4 females and 1 individual of unknown sex. Interestingly, 2 fecal samples that were presumed to be from tigers were from Amur leopards, highlighting the significant advantages of noninvasive genetics over traditional methods in studying rare and elusive animals. Analyses from this sample suggested that the genetic diversity of wild Amur tigers is much lower than that of Bengal tigers, consistent with previous findings. Furthermore, the genetic diversity of this Hunchun population in China was lower than that of the adjoining subpopulation in southwest Primorye Russia, likely due to sampling bias. Considering the small population size and relatively low genetic diversity, it is urgent to protect this endangered local subpopulation in China.

    Full Text Available Background The number of culturally and linguistically diverse students in the U.S. is growing, and research shows they are often underassessed, misdiagnosed, and placed into special education unnecessarily. This problem mainly concerns high-incidence, or judgmental, disabilities such as learning disability, emotional disturbance, or mental retardation. Participants and procedure In this study, the author examines how some educators perceive and address culturally and linguistically diverse students in the U.S. A survey developed by the author was used to examine how educators perceive culturally and linguistically diverse student populations and how one Midwestern school system in the United States dealt with culturally and linguistically diverse students’ needs versus expected ideal practices. Results Results indicated that most participants recognized that the issue of disproportionate representation is nationwide, but did not believe that their district shared that problem. Conclusions Participants indicated that best practices were not being followed maximally to reduce and avoid the problem of disproportionate representation of culturally and linguistically diverse students in special education programs. Difficulties in meeting students’ needs may be related to cultural differences that school personnel are unable to assess or address. Recommendations include suggestions for further studies and for applying the survey in other school systems to increase the understanding and improve their practice in working with culturally and linguistically diverse students.

  7. Genomic Characterization of Dairy Associated Leuconostoc Species and Diversity of Leuconostocs in Undefined Mixed Mesophilic Starter Cultures

    Undefined mesophilic mixed (DL-type) starter cultures are composed of predominantly Lactococcus lactis subspecies and 1–10% Leuconostoc spp. The composition of the Leuconostoc population in the starter culture ultimately affects the characteristics and the quality of the final product. The scientific basis for the taxonomy of dairy relevant leuconostocs can be traced back 50 years, and no documentation on the genomic diversity of leuconostocs in starter cultures exists. We present data on the Leuconostoc population in five DL-type starter cultures commonly used by the dairy industry. The analyses were performed using traditional cultivation methods, and further augmented by next-generation DNA sequencing methods. Bacterial counts for starter cultures cultivated on two different media, MRS and MPCA, revealed large differences in the relative abundance of leuconostocs. Most of the leuconostocs in two of the starter cultures were unable to grow on MRS, emphasizing the limitations of culture-based methods and the importance of careful media selection or use of culture independent methods. Pan-genomic analysis of 59 Leuconostoc genomes enabled differentiation into twelve robust lineages. The genomic analyses show that the dairy-associated leuconostocs are highly adapted to their environment, characterized by the acquisition of genotype traits, such as the ability to metabolize citrate. In particular, Leuconostoc mesenteroides subsp. cremoris display telltale signs of a degenerative evolution, likely resulting from a long period of growth in milk in association with lactococci. Great differences in the metabolic potential between Leuconostoc species and subspecies were revealed. Using targeted amplicon sequencing, the composition of the Leuconostoc population in the five commercial starter cultures was shown to be significantly different. Three of the cultures were dominated by Ln. mesenteroides subspecies cremoris. Leuconostoc pseudomesenteroides dominated in two of

    2012-02-01

    Full Text Available  Construction sites around the world employ large numbers of people from diverse cultural backgrounds. The effective management of this cultural diversity has important implications for the productivity, safety, health and welfare of construction workers and for the performance and reputation of firms which employ them. The findings of a three year, multi-staged study of cultural diversity management practices on construction sites are critiqued using social identity theory. This reveals that so called “best-practice” diversity management strategies may have an opposite effect to that intended. It is concluded that the management of diversity on construction projects would benefit from being informed by social identity research.

  16. Population size vs. social connectedness - A gene-culture coevolutionary approach to cumulative cultural evolution.

    Science.gov (United States)

    Kobayashi, Yutaka; Ohtsuki, Hisashi; Wakano, Joe Y

    2016-10-01

    It has long been debated if population size is a crucial determinant of the level of culture. While empirical results are mixed, recent theoretical studies suggest that social connectedness between people may be a more important factor than the size of the entire population. These models, however, do not take into account evolutionary responses of learning strategies determining the mode of transmission and innovation and are hence not suitable for predicting the long-term implications of parameters of interest. In the present paper, to address this issue, we provide a gene-culture coevolution model, in which the microscopic learning process of each individual is explicitly described as a continuous-time stochastic process and time allocation to social and individual learning is allowed to evolve. We have found that social connectedness has a larger impact on the equilibrium level of culture than population size especially when connectedness is weak and population size is large. This result, combined with those of previous culture-only models, points to the importance of studying separate effects of population size and internal social structure to better understand spatiotemporal variation in the level of culture.

    The underrepresentation of minorities among health care providers and researchers is often considered one of the contributing factors to health disparities in these populations. Recent demographic shifts and the higher proportion of minorities anticipated among the newly insured under the Patient Protection and Affordable Care Act make the need for a more diverse and culturally competent health care workforce an urgent national priority.The authors describe current and future strategies that have been developed at the College of Health Sciences and Human Services at the University of Texas-Pan American (an institution with 89% Hispanic students in 2012) to prepare a culturally competent and ethnically diverse health care workforce that can meet the needs of a diverse population, especially in the college's own community. The college graduates approximately 650 students annually for careers in nursing, physician assistant studies, occupational therapy, pharmacy, rehabilitation services, clinical laboratory sciences, dietetics, and social work. The college's approach centers on enriching student education with research, service, and community-based experiences within a social-determinants-of-health framework. The approach is promoted through an interdisciplinary health disparities research center, multiple venues for community-based service learning, and an innovative approach to improve cultural and linguistic competence. Although the different components of the college's approach are at different developmental stages and will benefit from more formal evaluations, the college's overall vision has several strengths that promise to serve as a model for future academic health initiatives.

    2007-01-01

    This article attempted to examine the relationship between cultural competence education and increasing diversity in nursing schools and practice settings. In addition to the review of the literature, a panel of experts was interviewed regarding institutional practices in response to the challenge of increasing diversity and cultural competence education. Evidence of positive outcomes of cultural competent care and impact of race and ethnic concordance between patients and providers are presented. The challenge of increasing underrepresented minorities in health care professions remains elusive. An ecological analysis is recommended to address the social and cultural barriers that transcend the micro system of the school and the macro system of the society. The challenge of increasing diversity and realizing outcomes of cultural competence education requires social and comprehensive remedies to level life inequities that perpetuate a history of disadvantages in some groups.

  10. Teaching science in culturally diverse classrooms: The relevance of multicultural coursework on novice teachers' instructional choice

    Cunha, Thais B. P. da

    Science education reform in the United States has been slow to reduce the troubling science achievement gap between students from mainstream and non-mainstream backgrounds. Recent data suggest the gap persists in spite of improved attention to the multicultural education of teachers, and in spite of recent, more culturally inclusive and responsive curricular materials and instructional recommendations. In this study, I examine the cases of two European American male novice science teachers in middle schools with highly diverse populations, exploring their perceptions of the necessity of adapting their instructional approaches and the science curricula in order to meet the needs of their predominantly Native American, Mexican American, and African American students. Two theoretical frameworks inform this study, Rodriguez's (2005) sociotransformative constructivism, and Freire's critical pedagogy. I apply a qualitative case study method, to better understand and analyze the classroom setting and power relations of the context. Data consist of semi-structured interviews with each teacher, classroom observation and other field notes, the science curricular and instructional materials, and teachers' lesson plans. Each teacher acknowledged the ethnicities of students positively and noticed distinctive ethnocultural features (e.g., quinceaneras, Mexican Americans). Yet, their teaching approaches were primarily teacher-centric and monocultural. Each followed the book, usually lecturing, and striving dutifully to "cover" the topics. They did not solicit students' knowledge or engage them in dialog to explore their thinking. Even when the curriculum guide detailed relevant science knowledge students of some cultural groups might have, both teachers declined to use it. These well-meaning teachers did not fully perceive that students whose culture was different from their own might have different and relevant knowledge, experiences, or histories which were resources for

    The population of students who are deaf or hard of hearing is becoming more culturally and/or linguistically diverse. However, there is a paucity of practitioner literature and research available to professionals and families to guide decision making about daily practices with these students and their families. The study identified factors that contribute to the success of students who are deaf or hard of hearing and from culturally and/or linguistically diverse backgrounds who receive the majority of their education in inclusive settings. Students were recruited from two schools in two school districts in a western state. Students, educators, interpreters, and parents participated in individual in-depth, semi-structured interviews. Observations of the students were also done. Analysis of the data included coding the transcribed interviews and the field notes to identify common themes. Seven themes emerged and are reported. Recommendations for future research are provided.

  12. Downscaling Climate Science to the Classroom: Diverse Opportunities for Teaching Climate Science in Diverse Ways to Diverse Undergraduate Populations

    Climate literacy and climate education are important topics in current socio-political debate. Despite numerous scientific findings supporting global climate changes and accelerated greenhouse warming, there is a social inertia resisting and slowing the rate at which many of our students understand and absorb these facts. A variety of reasons, including: socio-economic interests, political and ideological biases, misinformation from mass media, inappropriate preparation of science teachers, and lack of numancy have created serious challenges for public awareness of such an important issue. Different agencies and organizations (NASA, NOAA, EPA, AGU, APS, AMS and others) have created training programs for educators, not involved directly in climatology research, in order to learn climate science in a consistent way and then communicate it to the public and students. Different approaches on how to deliver such information to undergraduate students in diverse environments is discussed based on the author's experiences working in different minority-serving institutions across the nation and who have attended AMS Weather and Climate Studies training workshops, MSI-REACH, and the School of Ice. Different parameters are included in the analysis: demographics of students, size of the institutions, geographical locations, target audience, programs students are enrolled in, conceptual units covered, and availability of climate-related courses in the curricula. Additionally, the feasibility of incorporating a laboratory and quantitative analysis is analyzed. As a result of these comparisons it seems that downscaling of climate education experiences do not always work as expected in every institution regardless of the student body demographics. Different geographical areas, student body characteristics and type of institution determine the approach to be adopted as well as the feasibility to introduce different components for weather and climate studies. Some ideas are shared

    The ecological "compensation principle" enunciated by Yu.I. Chernov, who suggested a higher level of compensatory diversity in communities depleted in composition, proved to be also applicable to a single population, as demonstrated in a model rodent species, mole vole with mono- and polymorphic coat color, using the methods of geometric morphometrics. The mandible shape diversity was significantly increased in the monomorphic as compared to polymorphic populations, in which the division of foraging activities between animals of different morphs led to a suppression of general morphological diversity.

    Our previous publications and the data presented here provide evidences on the ability of plant-based culture media to optimize the cultivability of rhizobacteria and to support their recovery from plant-soil environments. Compared to the tested chemically-synthetic culture media (e.g. nutrient agar and N-deficient combined-carbon sources media), slurry homogenates, crude saps, juices and powders of cactus (Opuntia ficus-indica) and succulent plants (Aloe vera and Aloe arborescens) were rich enough to support growth of rhizobacteria. Representative isolates of Enterobacter spp., Klebsiella spp., Bacillus spp. and Azospirillum spp. exhibited good growth on agar plates of such plant-based culture media. Cell growth and biomass production in liquid batch cultures were comparable to those reported with the synthetic culture media. In addition, the tested plant-based culture media efficiently recovered populations of rhizobacteria associated to plant roots. Culturable populations of >106–108 cfu g−1 were recovered from the ecto- and endo-rhizospheres of tested host plants. More than 100 endophytic culture-dependent isolates were secured and subjected to morphophysiological identification. Factor and cluster analyses indicated the unique community structure, on species, genera, class and phyla levels, of the culturable population recovered with plant-based culture media, being distinct from that obtained with the chemically-synthetic culture media. Proteobacteria were the dominant (78.8%) on plant-based agar culture medium compared to only 31% on nutrient agar, while Firmicutes prevailed on nutrient agar (69%) compared to the plant-based agar culture media (18.2%). Bacteroidetes, represented by Chryseobacterium indologenes, was only reported (3%) among the culturable rhizobacteria community of the plant-based agar culture medium. PMID:26966571

    To obtain the perspectives of medical students at one school on racial/ethnic campus diversity and cultural competence and to gain their perceptions of the institutional climate around diversity at their university and of reasons for minority underrepresentation at their medical school. A student-driven survey of all medical students (N = 398) at a single medical school in the spring of 2003, supplemented by four focus groups from all racial and ethnic groups on the campus. A large majority of the responding students (n = 216; 54%) endorsed the value of campus diversity and the importance of cultural competence to the process of becoming a clinician. Most students felt their university had achieved a positive cultural climate, characterized by openness to diverse perspectives and attention to equity. Most students also felt that the university's programs and policies reflected a commitment to diversity, but fewer students--those from underrepresented minorities (URMs) in particular--felt that the university truly valued having a diverse student body and faculty. Most students felt that the lack of diversity on campus was a barrier to recruiting and retaining minority candidates. Some minority students also blamed the medical school's limited social, academic, and financial support, as well as inadequate efforts to recruit minority students. Medical students generally place a high value on campus diversity and cultural competence. URM students in particular felt that their university could do more to implement its commitment to diversity, including making greater efforts to recruit and retain URM students. These views constitute a barometer for medical schools to gauge and track their efforts to enhance campus diversity, incorporate cultural competence education, and create an inclusive and welcoming climate for students of all backgrounds.

    Tribal populations of the Indian subcontinent have been of longstanding interest to anthropologists and human geneticists. To investigate the relationship of Indian tribes to Indian castes and continental populations, we analyzed 45 unlinked autosomal STR loci in 9 tribal groups, 8 castes, and 18 populations from Africa, Europe and East Asia. South Indian tribal populations demonstrate low within-population heterozygosity (range: 0.54 - 0.69), while tribal populations sampled further north and east have higher heterozygosity (range: 0.69 - 0.74). Genetic distance estimates show that tribal Indians are more closely related to caste Indians than to other major groups. Between-tribe differentiation is high and exceeds that for eight sub-Saharan African populations (4.8% vs. 3.7%). Telugu-speaking populations are less differentiated than non-Telugu speakers (F(ST): 0.029 vs. 0.079), but geographic distance was not predictive of genetic affinity between tribes. South Indian tribes show significant population structure, and individuals can be clustered statistically into groups that correspond with their tribal affiliation. These results are consistent with high levels of genetic drift and isolation in Indian tribal populations, particularly those of South India, and they imply that these populations may be potential candidates for linkage disequilibrium and association mapping.

    This essay attempts to explore the current cultural diversity in China and India with the comparison of policy responses, especially the multiculturalism and language policies, as well as the policies on the workplace. Results show that India enriched and deepened its multiculturalism through the recognition of languages diversity, while China weakened its cultural diversity by popularizing one official language, Mandarin. However, both China and India should do more in practice to make different ethnic groups live and participant as equal partners in the social life.

Actinobacterial diversity has been thoroughly researched in various environments due to its unique biotechnological potential. Such studies have focused mostly on soil communities, but more recently marine and extreme environments have also been explored, finding rare taxa and demonstrating dispersal limitation and biogeographic patterns for Streptomyces. To test the distribution of Actinobacteria populations on a small scale, we chose the extremely oligotrophic and biodiverse Cuatro Cienegas Basin (CCB, an endangered oasis in the Chihuahuan desert to assess the diversity and uniqueness of Actinobacteria in the Churince System with a culture-dependent approach over a period of three years, using nine selective media. The 16S rDNA of putative Actinobacteria were sequenced using both bacteria universal and phylum-specific primer pairs. Phylogenetic reconstructions were performed to analyze OTUs clustering and taxonomic identification of the isolates in an evolutionary context, using validated type species of Streptomyces from previously phylogenies as a reference. Rarefaction analysis for total Actinobacteria and for Streptomyces isolates were performed to estimate species’ richness in the intermediate lagoon (IL in the oligotrophic Churince system. A total of 350 morphologically and nutritionally diverse isolates were successfully cultured and characterized as members of the Phylum Actinobacteria. A total of 105 from the total isolates were successfully subcultured, processed for DNA extraction and 16S-rDNA sequenced.

  17. The interface between bioethics and cultural diversity under the Universal Declaration on Bioethics and Human Rights.

    Lo, Chang-fa

    2008-06-01

    The Universal Declaration on Bioethics and Human Rights has made clear its aims to provide a universal framework of principles and procedures to guide States in the formulation of their legislation, policies or other instruments in the field ofbioethics and also to guide the actions of individuals, groups, communities, institutions and corporations so as to promote appreciation for human dignity and to protect human rights. It also sets up 15 principles to be applied. One of the principles in the Declaration is about the recognition of cultural diversity as an important element of bioethics. Thus it is clear that bioethics has its relativeness and is susceptible to different cultures. However, in order not to have the bioethics principles being defeated because of the cultural factor, the Declaration set forth conditions to limit the application of the cultural diversity element. This approach is called "qualified absoluteness" by the author. The paper discusses these conditions and the problems arising from their applications. Basically, there is a clear line drawn to limit the application of cultural diversity in setting up and in applying bioethical rules. The line drawn is based on the concept of human rights, the principles and concepts of which have not only been set forth in the Human Rights Convention, but have also been prescribed in other provisions in the Declaration. From conceptual viewpoint, the Declaration has listed a number of soft-law rules, which in turn also provide authorization for the government or private or public groups to take cultural diversity into account. Although the rules set forth in most of the parts in the Declaration are of soft but absolute mandates in nature, the requirement of paying due regard to cultural diversity is in fact providing governments as well as groups a possibility to enact or apply their bioethical rules to reflect their cultural uniqueness. The term "qualified absoluteness" is used in this paper to reflect

  18. Inverting faces does not abolish cultural diversity in eye movements.

    Science.gov (United States)

    Rodger, Helen; Kelly, David J; Blais, Caroline; Caldara, Roberto

    2010-01-01

    Face processing is widely understood to be a basic, universal visual function effortlessly achieved by people from all cultures and races. The remarkable recognition performance for faces is markedly and specifically affected by picture-plane inversion: the so-called face-inversion effect (FIE), a finding often used as evidence for face-specific mechanisms. However, it has recently been shown that culture shapes the way people deploy eye movements to extract information from faces. Interestingly, the comparable lack of experience with inverted faces across cultures offers a unique opportunity to establish the extent to which such cultural perceptual biases in eye movements are robust, but also to assess whether face-specific mechanisms are universally tuned. Here we monitored the eye movements of Western Caucasian (WC) and East Asian (EA) observers while they learned and recognised WC and EA inverted faces. Both groups of observers showed a comparable impairment in recognising inverted faces of both races. WC observers deployed a scattered inverted triangular scanpath with a bias towards the mouth, whereas EA observers uniformly extended the focus of their fixations from the centre towards the eyes. Overall, our data show that cultural perceptual differences in eye movements persist during the FIE, questioning the universality of face-processing mechanisms.

  19. Diversity of endophytic bacteria of Dendrobium officinale based on culture-dependent and culture-independent methods

    Directory of Open Access Journals (Sweden)

    Cong Pei

    2017-01-01

    Full Text Available Culture-dependent and culture-independent methods were compared and evaluated in the study of the endophytic diversity of Dendrobium officinale. Culture-independent methods consisted of polymerase chain reaction–denaturing gradient gel electrophoresis (PCR-DGGE and metagenome methods. According to the results, differences were found between the three methods. Three phyla, namely Firmicutes, Proteobacteria, and Actinobacteria, were detected using the culture-dependent method, and two phyla, Firmicutes and Proteobacteria, were detected by the DGGE method. Using the metagenome method, four major phyla were determined, including Proteobacteria (76.54%, Actinobacteria (18.56%, Firmicutes (2.27%, and Bacteroidetes (1.56%. A distinct trend was obtained at the genus level in terms of the method and the corresponding number of genera determined. There were 449 genera and 16 genera obtained from the metagenome and DGGE methods, respectively, and only 7 genera were obtained through the culture-dependent method. By comparison, all the genera from the culture-dependent and DGGE methods were contained in the members determined using the metagenome method. Overall, culture-dependent methods are limited to ‘finding’ endophytic bacteria in plants. DGGE is an alternative to investigating primary diversity patterns; however, the metagenome method is still the best choice for determining the endophytic profile in plants. It is essential to use multiphasic approaches to study cultured and uncultured microbes.

  20. Managing cultural diversity and the process of knowledge sharing: A case from Denmark

    2009-01-01

    Ideas of linking cultural diversity and knowledge resources have recently gained momentum in organizational literature, however, little is known about actual knowledge-sharing processes in culturally diverse organizations. This paper contributes to mending such limitations by first reviewing three...... dominant perspectives in the literature relevant to understanding these processes. It is then argued that these perspectives contribute focusing on different aspects of human diversity in organizations and, therefore, that they should not be separated in the analysis of the complex settings that culturally...... diverse organizations represent. This is illustrated with data from an ethnographic fieldwork in a Danish multicultural organization. The final section reflects on implications of using a combination of different theories in analyzing the results, and suggests other possibilities for future research....

  1. Initial genetic diversity enhances population establishment and alters genetic structuring of a newly established Daphnia metapopulation.

    2016-07-01

    When newly created habitats are initially colonized by genotypes with rapid population growth rates, later arriving colonists may be prevented from establishing. Although these priority effects have been documented in multiple systems, their duration may be influenced by the diversity of the founding population. We conducted a large-scale field manipulation to investigate how initial clonal diversity influences temporal and landscape patterns of genetic structure in a developing metapopulation. Six genotypes of obligately asexual Daphnia pulex were stocked alone (no clonal diversity) or in combination ('high' clonal diversity) into newly created experimental woodland ponds. We also measured the population growth rate of all clones in the laboratory when raised on higher-quality and lower-quality resources. Our predictions were that in the 3 years following stocking, clonally diverse populations would be more likely to persist than nonclonally diverse populations and exhibit evidence for persistent founder effects. We expected that faster growing clones would be found in more pools and comprise a greater proportion of individuals genotyped from the landscape. Genetic composition, both locally and regionally, changed significantly following stocking. Six of 27 populations exhibited evidence for persistent founder effects, and populations stocked with 'high' clonal diversity were more likely to exhibit these effects than nonclonally diverse populations. Performance in the laboratory was not predictive of clonal persistence or overall dominance in the field. Hence, we conclude that although laboratory estimates of fitness did not fully explain metapopulation genetic structure, initial clonal diversity did enhance D. pulex population establishment and persistence in this system.

    The combined effect of the steady increase in cultural and linguistic diversity and epidemiological factors in minority populations is estimated to continue having an impact on adult neurorehabilitation programs in the country, particularly in the number of bilingual individuals receiving clinical services. No comprehensive assessment of the present professional and clinical realities in service delivery to communicatively impaired adults in culturally and linguistically diverse (CLD) neurorehabilitation contexts has been conducted. The current survey research was undertaken to examine current professional training, clinical practices, and challenges in the services rendered to the steadily increasing numbers of communicatively disordered adults in CLD neurorehabilitation programs with a special focus on bilingual persons. A 36-question, 6-section survey was administered to health care-based SLPs working with adults to examine multiple factors regarding work setting and caseload, professional training, clinical tools and procedures, service delivery issues, and suggestions to improve clinical work with bilingual adults in CLD neurorehabilitation environments. Results support that SLPs presently make sensible decisions to serve communicatively disordered bilingual adults with neuropathologies despite training gaps and scant clinical resources. Responses additionally highlight critical areas to improve professional preparation and available resources. Results are discussed in terms of strengths and weaknesses as well as their implications to professional education and target research areas in order to minimize present gaps in service delivery with bilingual speakers in CLD adult neurorehabilitation programs. As a result of this activity, the reader will be able to: (1) Discuss the demographic and epidemiological factors that suggest a continued increase in the number of communicatively impaired bilingual adults in CLD neurorehabilitation programs. (2) Describe

    Detecting potential changes in genetic diversity in schistosome populations following chemotherapy with praziquantel (PZQ) is crucial if we are to fully understand the impact of such chemotherapy with respect to the potential emergence of resistance and/or other evolutionary outcomes of interventions. Doing so by implementing effective, and cost-efficient sampling protocols will help to optimise time and financial resources, particularly relevant to a disease such as schistosomiasis currently reliant on a single available drug. Here we explore the effect on measures of parasite genetic diversity of applying various field sampling approaches, both in terms of the number of (human) hosts sampled and the number of transmission stages (miracidia) sampled per host for a Schistosoma mansoni population in Tanzania pre- and post-treatment with PZQ. In addition, we explore population structuring within and between hosts by comparing the estimates of genetic diversity obtained assuming a 'component population' approach with those using an 'infrapopulation' approach. We found that increasing the number of hosts sampled, rather than the number of miracidia per host, gives more robust estimates of genetic diversity. We also found statistically significant population structuring (using Wright's F-statistics) and significant differences in the measures of genetic diversity depending on the parasite population definition. The relative advantages, disadvantages and, hence, subsequent reliability of these metrics for parasites with complex life-cycles are discussed, both for the specific epidemiological and ecological scenario under study here and for their future application to other areas and schistosome species.

    A dearth of data concerning eating problems among adult women from minority population groups leaves substantial knowledge gaps and constrains evidence-based interventions. To examine prevalence and predictors of disordered eating behaviors (DEB) among Arab Muslim women in Israel, whose eating behaviors have not been previously examined and to compare with second generation Israeli-born Jews of European heritage. Community-based study includes sub-samples of Arab Muslims and Israeli-born Jews. DEB is assessed with fourteen DSM-IV related symptoms. Hierarchical regressions examine influence of weight, self-criticism and psychological distress on DEB severity. Relatively high prevalence rates emerge for Muslims (27%) and Jews (20%), a nonsignificant difference. In contrast, regressions reveal substantially different predictor patterns. For Arab Muslims, weight has the strongest association; for Jews, weight is not significant while self-criticism is the strongest predictor. Explained variance also differs considerably: 45% for Muslims and 28% for Jews. Surprising similarities and distinct differences underscore complex patterns of eating disturbances across culturally diverse groups. Culturally sensitive interventions are warranted along with more illuminating explanatory paradigms than 'one size fits all.' Copyright © 2014 Elsevier Ltd. All rights reserved.

    If human culture emerges from the modal personality of a population, can global variation in parasitism that affects personality lead to cultural diversity among nations? The answer could help explain why people seem to vary so much from one land to another. Thomas et al. (2005) review how parasites manipulate behaviour, including human behaviour. To quote them, “The rabies virus lives in the brain, affording the virus ample opportunity to directly affect host behaviour. Rabid animals do show changes in behaviour, including increased aggression and biting.” Rabies affects a wide range of mammals and the aggressive biting associated with furious rabies appears to increase transmission. The personality transformation of infected humans can be horrifying, transforming loved ones into thrashing, baying beasts. Not coincidentally, in Europe, past periods of rabies outbreaks correspond to increases in werewolf trials. Although rabies can have a dramatic effect, the present rarity of human rabies cases and the availability of a vaccine, means that the behavioural effects of rabies are primarily an illustrative curiosity.

    The effect of evolutionary changes in traits and phenotypic/genetic diversity on ecological dynamics has received much theoretical attention; however, the mechanisms and ecological consequences are usually unknown. Female-limited colour polymorphism in damselflies is a counter-adaptation to male mating harassment, and thus, is expected to alter population dynamics through relaxing sexual conflict. Here we show the side effect of the evolution of female morph diversity on population performance (for example, population productivity and sustainability) in damselflies. Our theoretical model incorporating key features of the sexual interaction predicts that the evolution of increased phenotypic diversity will reduce overall fitness costs to females from sexual conflict, which in turn will increase productivity, density and stability of a population. Field data and mesocosm experiments support these model predictions. Our study suggests that increased phenotypic diversity can enhance population performance that can potentially reduce extinction rates and thereby influence macroevolutionary processes.

    An urban teaching facility with nearly 3,000 employees had communication problems associated with race, gender and other cultural differences. It also competed for health care dollars and faced possible reduction in federal funding. The medical center instituted mandatory training in cultural diversity and customer service-and integrated the training process with the hospital's overall quality improvement plan and marketing strategy. The integrated approach affected the bottom line-Hurley's patient base has increased, and the medical center operates in the black. Training in cultural diversity and customer service is an effective tool to improve employee communication and improve financial outlook.

  9. Meeting the Challenge of Diabetes in Ageing and Diverse Populations: A Review of the Literature from the UK

    Full Text Available The impact of type 2 diabetes on ageing societies is great and populations across the globe are becoming more diverse. Complications of diabetes unequally affect particular groups in the UK older people, and people with a South Asian background are two population groups with increased risk whose numbers will grow in the future. We explored the evidence about diabetes care for older people with South Asian ethnicity to understand the contexts and mechanisms behind interventions to reduce inequalities. We used a realist approach to review the literature, mapped the main areas where relevant evidence exists, and explored the concepts and mechanisms which underpinned interventions. From this we constructed a theoretical framework for a programme of research and put forward suggestions for what our analysis might mean to providers, researchers, and policy makers. Broad themes of cultural competency; comorbidities and stratification; and access emerged as mid-level mechanisms which have individualised, culturally intelligent, and ethical care at their heart and through which inequalities can be addressed. These provide a theoretical framework for future research to advance knowledge about concordance; culturally meaningful measures of depression and cognitive impairment; and care planning in different contexts which support effective diabetes care for aging and diverse populations.

  10. Diverse decisions. How culture affects ethical decision making.

    Even under optimal conditions, assisting patients and families in making ethical decisions is difficult at best. Often these decisions revolve around the end-of-life issues that require acknowledgement that the patient is unlikely to survive, which may be perceived as a failure to both the family and the staff. At the very least, it can be a sad time, fraught with uncertainty and indecision. When these difficulties are coupled with ineffective communication related to cultural insensitivity or unawareness, the effects can be devastating to the decision-making process. All CCNs are expected to master the skills necessary for assisting patients and families through the harrowing experience of life-threatening illness. Whereas much of critical care focuses on managing pathophysiologic disturbances, emotional needs are equally important. It follows then that the CCN must assume responsibility for assisting patients and families in coping with the crisis of critical illness and working through ethical issues, which often include end-of-life decisions and organ donation. Culturally competent care is required when addressing patient needs holistically, but it is so much more. It is an opportunity to enrich and deepen the CCN/patient/family relationship, advocate for the patient, and broaden the opportunities for communication among staff. This article has provided some beginning steps for increasing nursing cultural awareness and has offered some initial strategies to consider when designing a plan of care. Through continuing efforts, CCNs and organizations can do much to decrease the alienation that many patients and families have traditionally encountered in the CCU, an estrangement that is exacerbated when their culture is different from the predominant culture of the unit. The effort to become more culturally aware may appear to require extraordinary effort; however, the rewards of optimizing patient care are unsurpassed.

    Similar to many developed nations, older people living in residential aged care homes in Australia and the staff who care for them have become increasingly multicultural. This cultural diversity adds challenges for residents in adapting to the care home. This study explores: (i) residents' and family members' perceptions about staff and cultural diversity, and (ii) culturally and linguistically diverse residents' and family members' experiences. An interpretive study design employing a thematic analysis was applied. Twenty-three residents and seven family members participated in interviews. Four themes were identified from interpreting residents and family members' perceptions of the impact of cultural diversity on their adaptation to aged care homes: (i) perceiving diversity as an attraction; (ii) adapting to cross-cultural communication; (iii) adjusting to diet in the residential care home; and (iv) anticipating individualized psychosocial interactions. The findings have implications for identifying strategies to support staff from all cultural backgrounds in order to create a caring environment that facilitates positive relationships with residents and supports residents to adjust to the care home.

    Rare Actinomycetes from underexplored marine environments are targeted in drug discovery studies due to the Actinomycetes' potentially huge resource of structurally diverse natural products with unusual biological activity. Of all marine bacteria, 10 % are Actinomycetes, which have proven an outstanding and fascinating resource for new and potent bioactive molecules. Past and present efforts in the isolation of rare Actinomycetes from underexplored diverse natural habitats have resulted in the isolation of about 220 rare Actinomycete genera of which more than 50 taxa have been reported to be the producers of 2,500 bioactive compounds. That amount represents greater than 25 % of the total Actinomycetes metabolites, demonstrating that selective isolation methods are being developed and extensively applied. Due to the high rediscovery rate of known compounds from Actinomycetes, a renewed interest in the development of new antimicrobial agents from rare and novel Actinomycetes is urgently required to combat the increasing number of multidrug-resistant human pathogens. To facilitate that discovery, this review updates all selective isolation media including pretreatment and enrichment methods for the isolation of marine rare Actinomycetes. In addition, this review demonstrates that discovering new compounds with novel scaffolds can be increased by intensive efforts in isolating and screening rare marine genera of Actinomycetes. Between 2007 and mid-2013, 80 new rare Actinomycete species were reported from marine habitats. They belong to 23 rare families, of which three are novel, and 20 novel genera. Of them, the family Micromonosporaceae is dominant as a producer of promising chemical diversity.

    Full Text Available The present study is based on a quasi-experimental research design and presents the results of an evaluation of Antidiscrimination and Diversity Training that took place at the Faculty of Education in Ljubljana, rooted in the anti-bias approach to educating diversity and equality issues (Murray & Urban, 2012. The experimental group included 52 in-service early childhood teachers attending the training, which consisted of a total of 120 hours. There was also a control group comprising 130 teachers. The ADT had a decisive impact on all of the measured variables: on an improvement in the participants’ knowledge of discrimination, and on increased support for positive measures and for the preservation of the cultural traditions and language of immigrant children. It was found that self-assessed personality characteristics are predictors of the teachers’ beliefs, especially the enjoying awareness of cultural differences variable, which correlates with all of the dependent variables.
