    This study examined demographic and denominational differences in religious involvement (i.e., organizational, non-organizational, subjective) among Caribbean Blacks (Black Caribbeans) residing in the U.S. using data from the National Survey of American Life. Caribbean Blacks who were born in the U.S. had lower levels of religious involvement than those who immigrated and respondents originating from Haiti (as compared to Jamaica) had higher levels of religious involvement, while persons from Trinidad-Tobago reported lower service attendance than did Jamaicans. Older persons, women and married persons generally demonstrated greater religious involvement than their counterparts, while highly educated respondents expressed lower levels of self-rated religiosity. Denominational differences indicated that Baptists reported high levels of religious involvement; however, in several cases, Pentecostals and Seventh Day Adventists reported greater involvement.

    The tripartite model of racism includes personally mediated racism, institutionalized racism, and the less-oft studied internalized racism. Internalized racism - or negative beliefs about one's racial group - results from cultural racism that is endemic in American society. In this project, we studied whether these negative stereotypes are associated with mental health among African-Americans and Caribbean Blacks. Using secondary data from the National Survey of American Life, we investigated the association between internalized racism and mental health (measured by depressive symptoms and serious psychological distress (SPD)) among these two groups. We also explored whether ethnicity/nativity and mastery moderate the association between internalized racism and mental health among African-Americans and Caribbean Blacks. Internalized racism was positively associated with depressive symptoms and SPD among all Black subgroups. However, internalized racism was a weaker predictor of SPD among foreign-born Caribbean Blacks than US-born Caribbean Blacks and US-born African-Americans. Additionally, higher mastery was protective against distress associated with internalized racism. Internalized racism is an important yet understudied determinant of mental health among Blacks. Future studies should take into account additional heterogeneity within the Black population (e.g. African-born individuals) and other potential protective mechanisms in addition to mastery (e.g. self-esteem and racial identity).

    The cultural context in the United States is racialized and influences Black Caribbean immigrants' acculturation processes, but what role it plays in Black Caribbean immigrants' acculturation into specific facets of American society (e.g., African American culture) has been understudied in the field of psychology. The present study extends research on Black Caribbean immigrants' acculturative process by assessing how this group's experience of the racial context (racial public regard, ethnic public regard, and cultural race-related stress) influences its engagement in African American culture (i.e., adoption of values and behavioral involvement). Data were collected from 93 Black participants of Caribbean descent, ranging in age from 13 to 45 and analyzed using a stepwise hierarchical regression. The findings highlighted that when Black Caribbean-descended participants perceived that the public held a favorable view of their racial group they were more likely to engage in African American culture. In contrast, when participants perceived that the public held a favorable view of their ethnic group (e.g., Haitian) they were less likely to engage in African American culture. Furthermore, among participants experiencing low levels of cultural race-related stress, the associations between racial public regard and engagement with African American culture were amplified. However, for participants experiencing high cultural race-related stress, their engagement in African American culture did not change as a function of racial public regard. These findings may suggest that, for Black Caribbean immigrants, the experience of the racial context influences strategies that serve to preserve or bolster their overall social status and psychological well-being in the United States.

    This study investigated the use of professional services and informal support among African Americans and Caribbean blacks with a lifetime mood, anxiety, or substance use disorder. Data were from the National Survey of American Life. Multinomial logistic regression was used to test the utilization of professional services only, informal support only, both, or neither. Analyses controlled for sociodemographic characteristics, disorder-related variables, and family network variables. The analytic sample included 1,096 African Americans and 372 Caribbean blacks. Forty-one percent used both professional services and informal support, 14% relied on professional services only, 23% used informal support only, and 22% did not seek help. There were no significant differences in help seeking between African Americans and Caribbean blacks. Having co-occurring mental and substance use disorders, having a severe disorder in the past 12 months, having more people in the informal helper network, and being female increased the likelihood of using professional services and informal supports. When men sought help, they were more likely to rely on informal helpers. Marital status, age, and socioeconomic status were also significantly related to help seeking. The significant proportion of black Americans with a mental disorder who relied on informal support alone, professional services alone, or no help at all suggests potential unmet need in this group. However, the reliance on informal support also may be evidence of a strong protective role that informal networks play in the lives of African Americans and Caribbean blacks.

    Objectives Understanding barriers to early diagnosis of symptomatic breast cancer among Black African, Black Caribbean and White British women in the UK. Design In-depth qualitative interviews using grounded theory methods to identify themes. Findings validated through focus groups. Participants 94 women aged 33–91 years; 20 Black African, 20 Black Caribbean and 20 White British women diagnosed with symptomatic breast cancer were interviewed. Fourteen Black African and 20 Black Caribbean women with (n=19) and without (n=15) breast cancer participated in six focus groups. Setting Eight cancer centres/hospital trusts in London (n=5), Somerset (n=1), West Midlands (n=1) and Greater Manchester (n=1) during 2012–2013. Results There are important differences and similarities in barriers to early diagnosis of breast cancer between Black African, Black Caribbean and White British women in the UK. Differences were influenced by country of birth, time spent in UK and age. First generation Black African women experienced most barriers and longest delays. Second generation Black Caribbean and White British women were similar and experienced fewest barriers. Absence of pain was a barrier for Black African and Black Caribbean women. Older White British women (≥70 years) and first generation Black African and Black Caribbean women shared conservative attitudes and taboos about breast awareness. All women viewed themselves at low risk of the disease, and voiced uncertainty over breast awareness and appraising non-lump symptoms. Focus group findings validated and expanded themes identified in interviews. Conclusions Findings challenged reporting of Black women homogenously in breast cancer research. This can mask distinctions within and between ethnic groups. Current media and health promotion messages need reframing to promote early presentation with breast symptoms. Working with communities and developing culturally appropriate materials may lessen taboos and stigma

    Among most minority groups, males seem to report higher levels of exposure and vulnerability to racial discrimination. Although darker skin tone may increase exposure to racial discrimination, it is yet unknown whether skin tone similarly influences perceived discrimination among male and female Caribbean Black youth. The current cross-sectional study tests the role of gender on the effects of skin tone on perceived discrimination among Caribbean Black youth. Data came from the National Survey of American Life-Adolescent Supplement (NSAL-A), 2003-2004, which included 360 Caribbean Black youth (ages 13 to 17). Demographic factors (age and gender), socioeconomic status (SES; family income, income to needs ratio, and subjective SES), skin tone, and perceived everyday discrimination were measured. Linear regressions were used for data analysis. In the pooled sample, darker skin tone was associated with higher levels of perceived discrimination among Caribbean Black youth ( b = 0.48; 95% Confidence Interval (CI) = 0.07-0.89). A significant interaction was found between gender and skin tone ( b = 1.17; 95% CI = 0.49-1.86), suggesting a larger effect of skin tone on perceived discrimination for males than females. In stratified models, darker skin tone was associated with more perceived discrimination for males ( b = 1.20; 95% CI = 0.69-0.72) but not females ( b = 0.06; 95% CI = -0.42-0.55). Similar to the literature documenting male gender as a vulnerability factor to the effects of racial discrimination, we found that male but not female Caribbean Black youth with darker skin tones perceive more discrimination.

    The present study investigated the relationship between discrimination and social anxiety disorder (SAD) in a sample of African-Americans, Caribbean blacks, and non-Hispanic whites using the National Survey of American Life, the most comprehensive study of psychopathology among American blacks to date (N = 6082). Previous work has highlighted a strong association between discrimination and mental health symptoms (Keith, Lincoln, Taylor, and Jackson [Sex Roles 62:48-59, ]; Kessler, Mickelson, and Williams [J Health Soc Behav 40:208-230, 1999]; Soto, Dawson-Andoh, and BeLue [J Anxiety Disord 25:258-265, ]). However, few studies have examined the effects of particular types of discrimination on specific anxiety disorders or among different black subgroups. In this study, logistic regression analyses indicated that everyday but not major experiences of discrimination are associated with SAD for African-Americans, Caribbean blacks, and non-Hispanic whites. This study adds to the extant literature by demonstrating that specific types of discrimination may be uniquely associated with SAD for different ethnic/racial groups.

    Research on Black sexual health often fails to represent the heterogeneity of Black ethnic groups. For people of Caribbean descent in the USA, ethnicity is a salient cultural factor that influences definitions and experiences of sexual health. Most research on people of Caribbean descent focuses on the relatively high rate of STIs, but sexual health is defined more broadly than STI prevalence. Psychological and emotional indicators and the voice of participants are important to consider when exploring the sexual health of a minority culture. The purpose of this study was to qualitatively explore how heterosexual Black men of Caribbean descent define and understand sexual health for themselves. Eleven men who self-identified as Black, Caribbean and heterosexual participated in three focus groups and were asked to define sexual health, critique behaviours expertly identified as healthy and address what encourages and discourages sexual health in their lives. Findings point to six dimensions of sexual health for heterosexual Black men of Caribbean descent. These include: heterosexually privileged, protective, contextual, interpersonal, cultural and pleasurable dimensions. There were some notable departures from current expert definitions of sexual health. Recommendations for further theory development are provided.

    This study examined racial and ethnic differences in the use of complementary and alternative medicine (CAM) for the treatment of mental and substance use disorders. Data were from the National Survey of American Life (NSAL) and the National Comorbidity Survey-Replication (NCS-R). The analytic sample included 631 African Americans and 245 black Caribbeans from the NSAL and 1,393 non-Hispanic whites from the NCS-R who met criteria for a mood, anxiety, or substance use disorder in the past 12 months. Logistic regression was used to examine racial and ethnic differences in the use of any CAM and in the use of CAM only versus the use of CAM plus services in another treatment sector. Thirty-four percent of respondents used some form of CAM. Whites were more likely than blacks to use any CAM, although there was no racial or ethnic difference in CAM use only versus CAM use plus traditional services. A higher proportion of blacks than whites used prayer and other spiritual practices. Among those with a mood disorder, black Caribbeans were less likely than African Americans to use any CAM. Findings of this study were similar to those of previous studies that examined physical illness in relation to CAM use in terms of its overall prevalence, the predominant use of CAM in conjunction with traditional service providers, and racial and ethnic differences in the use of CAM. The use of prayer was a major factor in differences between blacks and whites in CAM use; however, there were also differences among black Americans that warrant further research.

    Prostate cancer (PC) is common and affects Black African and Caribbean men disproportionately more than White men. It is known that PC awareness is low in these groups, but knowledge is lacking about other factors that may deter Black men from seeking information about, or getting tested for, PC. The aim of this review was to appraise research on knowledge and perceptions of PC among Black men. Four medical and social science databases were systematically searched, and reference lists of relevant papers were hand searched. Non-English publications were excluded. Qualitative findings were synthesised using comparative thematic analysis to which quantitative findings were integrated. Thirteen qualitative studies and 20 cross-sectional surveys were included. All except two were conducted in the USA. The analysis identified individual, cultural and social factors likely to impact on Black men's awareness of, and willingness to be tested for, PC. Black men's awareness of personal risk of PC varied greatly between studies. Misunderstandings regarding methods of diagnosis and treatment were widespread. PC testing and treatment were perceived as a threat to men's sense of masculinity. Mistrust of the health-care system, limited access to health care and lack of trusting relationships with health professionals were also prominent. The factors impacting on Black men's awareness of PC may contribute to late PC diagnosis and should be taken into account when communicating with Black men seeking prostate care. Further, the review demonstrated a need for high-quality studies in countries other than the USA to determine the relevance of the review findings for Black men in other nations and continents.

    2013-10-01

    This study examines the relationship between religious involvement and 12-month and lifetime DSM-IV major depressive disorder (MDD) within a nationally representative sample of Black Caribbean adults. MDD was assessed using the DSM-IV World Mental Health Composite International Diagnostic Interview (WMH-CIDI). Religious involvement included measures of religious coping, organizational and nonorganizational involvement, and subjective religiosity. Study findings indicate that religious involvement is associated with 12-month and lifetime prevalence of MDD. Multivariate relationships between religious involvement and MDD indicate lower prevalence of 12-month and lifetime MDD among persons who use religious coping and characterize themselves as being religious (for lifetime prevalence only); persons who frequently listen to religious radio programs report higher lifetime MDD. Lower rates of 12-month and lifetime MDD are noted for persons who attend religious services at least once a week (as compared to both higher and lower levels of attendance), indicating a curvilinear relationship. The findings are discussed in relation to previous research on religion and mental health concerns, conceptual models of the role of religion in mental health (e.g., prevention, resource mobilization) that specify multiple and often divergent pathways and mechanisms of religious effects on health outcomes, and the role of religion among Caribbean Blacks.

    Currently the demand for transplant organs, particularly kidneys, far outstrips the supply in the United Kingdom. This problem is particularly severe for the Black African and Black Caribbean populations who have a higher predisposition to end-stage renal failure. Several commentators have suggested that religious and cultural traditions may be the major determinant preventing Black Africans and Black Caribbeans from donating organs. An exploratory qualitative study using focus groups was undertaken with the aim of examining the influence of religion, among other things, on the extent and direction of public attitudes toward organ donation in a cross-section of the Black African and Black Caribbean populations in Lambeth, Southwark, and Lewisham. In almost every focus group, religion and faith were expressed as issues that could prevent Black people from becoming organ donors. Organ donation was debated with caution on the basis of how their religious experience had influenced them. This finding suggests that the church and faith leaders could play a greater role in raising awareness of organ donation in these communities. Religious leaders can reach large numbers of people in a short space of time and will assist members of any group to understand more fully the religious stance on the subject matter. This education, in the long term, may lead to more people becoming organ donors.

  1. Mechanisms involved in the psychological distress of Black Caribbeans in the United States

    Govia, Ishtar O.

    The mental health of ethnic minorities in the United States is of urgent concern. The accelerated growth of groups of ethnic minorities and immigrants in the United States and the stressors to which they are exposed, implores academic researchers to investigate more deeply health disparities and the factors that exacerbate or minimize such inequalities. This dissertation attended to that concern. It used data from the National Survey of American Life (NSAL), the first survey with a national representative sample of Black Caribbeans, to explore mechanisms that involved in the psychological distress of Black Caribbeans in the United States. In a series of three studies, the dissertation investigated the role and consequence of (1) chronic discrimination, immigration factors, and closeness to ethnic and racial groups; (2) personal control and social support; and (3) family relations and social roles in the psychological distress of Black Caribbeans. Study 1 examined how the associations between discrimination and psychological distress were buffered or exacerbated by closeness to ethnic group and closeness to racial group. It also examined how these associations differed depending on immigration factors. Results indicated that the buffering or exacerbating effect of ethnic and racial group closeness varied according to the type of discrimination (subtle or severe) and were more pronounced among those born in the United States. Using the stress process framework, Study 2 tested moderation and mediation models of the effects of social support and personal control in the association between discrimination and distress. Results from a series of analyses on 579 respondents suggested that personal control served as a mediator in this relationship and that emotional support exerted a direct distress deterring function. Study 3 investigated sex differences in the associations between social roles, intergenerational family relationship perceptions and distress. Results

    To contribute to the growing understanding of U.S. black-white health disparities by examining psychosocial stress as an important contributor to physical health problems. Data are from the National Survey of American Life, an integrated national household probability sample of White Americans, African Americans, and Caribbean blacks. Regression analysis was used to assess associations between goal-striving stress and hypertension, BMI, physical health problems, and self-rated health. After accounting for sociodemographic factors and three additional stressors--personal problems, lifetime racial discrimination, and everyday racial discrimination-goal-striving stress was a significant predictor of hypertension, physical health problems, and diminished self-rated health. Ethnicity moderated the relationship; the negative association between goal-striving stress and physical health problems was strongest for Caribbean blacks. This study extends the research on goal-striving stress and adds to a growing literature documenting relationships between social processes and disease.

    The present study examined whether combinations of ethnicity, gender, and age moderated the association between perceived discrimination and psychological well-being indicators (depressive symptoms, self-esteem, and life satisfaction) in a nationally representative sample of Black youth. The data were from the National Survey of American Life, which includes 810 African American and 360 Caribbean Black adolescents. The results indicated main effects such that perceived discrimination was linked to increased depressive symptoms and decreased self-esteem and life satisfaction. Additionally, there were significant interactions for ethnicity, gender, and race. Specifically, older Caribbean Black female adolescents exhibited higher depressive symptoms and lower life satisfaction in the context of high levels of perceived discrimination compared with older African American male adolescents.

    There is evidence that religion and spirituality affect psychosocial adjustment to cancer. However, little is known about the perceptions and meanings of religion and spirituality among Black and minority ethnic groups living with cancer in the UK. We conducted semi-structured interviews with 26 Black Caribbean and 19 White British patients living in South London boroughs with advanced cancer to explore how religion and spirituality influenced their self-reported cancer experience. Twenty-five Black Caribbean patients and 13/19 White British patients volunteered views on the place of religion or God in their life. Spirituality was rarely mentioned. Christianity was the only religion referred to. Strength of religious belief appeared to be more pronounced among Black Caribbean patients. Three main themes emerged from patients' accounts: the ways in which patients believed religion and belief in God helped them comprehend cancer; how they felt their faith and the emotional and practical support provided by church communities assisted them to live with the physical and psychological effects of their illness and its progression; and Black Caribbean patients identified the ways in which the experience of cancer promoted religious identity. We identified that patients from both ethnic groups appeared to derive benefit from their religious faith and belief in God. However, the manner in which these were understood and expressed in relation to their cancer was culturally shaped. We recommend that when health and social care professionals perform an assessment interview with patients from different cultural backgrounds to their own, opportunities are made for them to express information about their illness that may include religious and spiritual beliefs since these may alter perceptions of their illness and symptoms and thereby influence treatment decisions.

    Black Caribbeans in the United States have been the victims of major discrimination (e.g. unfairly fired, denied a promotion, denied housing). What is not known is the degree to which they also experience more routine forms of everyday discrimination such as receiving poor restaurant service, being perceived as dishonest, and being followed in stores. This paper investigates the distribution and correlates of everyday discrimination among a national sample of black Caribbeans in the U.S. This analysis used the black Caribbean sub-sample (n = 1,621) of the National Survey of American Life. Demographic and immigration status correlates of ten items from the Everyday Discrimination Scale were investigated: being treated with less courtesy, treated with less respect, receiving poor restaurant service, being perceived as not smart, being perceived as dishonest, being perceived as not as good as others, and being feared, insulted, harassed, or followed in stores. Roughly one out of ten black Caribbeans reported that, on a weekly basis, they were treated with less courtesy and other people acted as if they were better than them, were afraid of them, and as if they were not as smart. Everyday discrimination was more frequent for black Caribbeans who were male, never married, divorced/separated, earned higher incomes, and who were second or third generation immigrants. Black Caribbeans attributed the majority of the discrimination they experienced to their race. To our knowledge, this is the first study to provide an in-depth investigation of everyday discrimination among the black Caribbean population. It provides the frequency, types and correlates of everyday discrimination reported by black Caribbeans in the United States. Understanding the frequency and types of discrimination is important because of the documented negative impacts of everyday discrimination on physical and mental health.

  6. Black African and Caribbean British Communities' Perceptions of Memory Problems: "We Don't Do Dementia.".

    Sharne Berwald

    Full Text Available We aimed to identify and explore the barriers to help-seeking for memory problems, specifically within UK Black African and Caribbean communities.We purposively recruited participants from community groups and subsequent snowball sampling, to achieve a maximum variation sample and employed thematic analysis. Our qualitative semi-structured interviews used a vignette portraying a person with symptoms of dementia, and we asked what they or their family should do. We stopped recruiting when no new themes were arising.We recruited 50 people from a range of age groups, country of origin, time in the UK, religion and socio-economic background. Some of the barriers to presentation with dementia have been reported before, but others were specific to this group and newly identified. Many people recognised forgetfulness but neither that it could be indicative of dementia, nor the concept of dementia as applying to them. Dementia was viewed as a white person's illness. Participants felt there was little point in consulting a doctor for forgetfulness. Many thought that seeing a GP was only for severe problems. Some said that their culture was secretive and highly valued privacy of personal affairs and therefore did not want to discuss what they regarded as a private and stigmatising problem with a GP. Participants did not appreciate their GP could refer to memory services who have more time and expertise. They were concerned about harm from medication and compulsory institutionalisation. Care should be from the family. Any intervention should emphasise the legitimacy of seeing a doctor early for memory concerns, that dementia is a physical illness which also occurs in the Black community, that help and time are available from memory services whose role is to prolong independence and support families in caring.

    The disproportionate HIV burden shared by African, Caribbean, and Black (ACB) populations in Canada has not been explained by unique sexual behaviors in this population. This study investigates partner selection and sexual networking as potential contributors to HIV vulnerability. The study examines variations in the characteristics of sexual partners and sexual networking across groups based on differences in ethno-religious identity, gender, and length of Canadian residency among single, 16- to 27-year old, heterosexual-identified, ACB individuals living in Windsor, Ontario, Canada. Respondent-driven sampling maximized the representativeness of the sample of 250 (45 % male; 55 % female) youth with penile-vaginal intercourse experience who completed surveys. Logistic regression and analysis of variance compared groups with respect to number of lifetime partners, concurrency of sexual relationships, non-relational and age disparate partnering, and intra-ethnic sexual networking. For vulnerability associated with number of partners, concurrency and non-relational sex, women, newcomers to Canada, and African-Muslim participants were at lower vulnerability for HIV infection than their comparator groups. For vulnerability associated with sexual networking within a group with higher HIV prevalence, women and newcomers to Canada were at higher vulnerability to HIV infection than their comparator groups. There were insufficient data on age disparate partnering to support analysis. These results point to the importance of considering characteristics of partners and sexual networking both in further research and in developing policies and programs to curtail the spread of HIV and other sexually transmitted infections.

    HIV-related stigma has been shown to undermine prevention, care, treatment, and the well-being of people living with HIV. A disproportion burden of HIV infection, as well as elevated levels of HIV-related stigma, is evidenced in sub-Saharan African (SSA) and African-diasporic populations. This study explores factors that influence HIV-related stigma among 16- to 25-year-old youth residing in a Canadian city who identify as African, Caribbean, or Black. Stigma, as rooted in cultural norms and beliefs and related social institutions, combined with insights from research on stigma in SSA and African-diasporic populations, guided the development of a path analytic structural equation model predicting levels of HIV-related stigmatizing attitudes. The model was tested using survey responses of 510 youth to estimate the direct and indirect influences of ethno-religious identity, religious service attendance, time in Canada, HIV/AIDS knowledge, HIV-testing history, sexual health service contact, and gender on HIV-related stigma. Statistically significant negative associations were found between levels of stigma and knowledge and HIV-testing history. Ethno-religious identity and gender had both direct and indirect effects on stigma. African-Muslim participants had higher levels of stigma, lower knowledge, and were less likely to have been tested for HIV infection than other ethno-religious groups. Male participants had higher levels of stigma and lower knowledge than women. Time in Canada had only indirect effects on stigma, with participants in Canada for longer periods having higher knowledge and less likely to have been tested than more recent arrivals. While the strength of the effect of knowledge on stigmatizing attitudes in this research is consistent with other research on stigma and evaluations of stigma-reduction programs, the path analytic results provide additional information about how knowledge and HIV-testing function as mediators of non

    Cancer fatalism is believed to be a major barrier for cancer screening in Black males. Therefore, the purpose of this study was to compare perceptions of prostate cancer (CaP) fatalism and predictors of CaP screening with Prostate Specific Antigen (PSA) testing between U.S.-born and Caribbean-born Black males. The Powe Fatalism Inventory and the Personal Integrative Model of CaP Disparity Survey were used to collect the following data from males in South Florida. Multivariate logistic regression models were constructed to examine the statistically significant predictors of CaP screening. A total of 211 U.S.-born and Caribbean-born Black males between ages 39-75 were recruited. Nativity was not a significant predictor of CaP screening with PSA testing within the last year (Odds ratio [OR] = 0.80, 95% confidence interval [CI] = 0.26, 2.48, p = 0.70). Overall, higher levels of CaP fatalism were not a significant predictor of CaP screening with PSA testing within the last year (OR = 1.37, 95% CI = 0.48, 3.91, p = 0.56). The study results suggest that nativity did not influence CaP screening with PSA testing. However, further studies are needed to evaluate the association between CaP screening behavior and levels of CaP fatalism.

    Using the National Survey of American Life, a nationally representative household survey of non-institutionalized US Blacks, our study examined whether the endorsement of racial/ ethnic stereotypes was associated with excess body fat composition among African Americans (n = 3,265) and Black Caribbeans (n = 1,332) living in the United States. We used ordinary least squares and multinomial logistic regression analyses controlling for potential confounders. Results from the linear regression suggested that the endorsement of racial/ethnic stereotypes was associated with increased body mass index and weight among African American males (b = .57, P females (b = .50 P Black Caribbeans. Future studies should examine the relationship between internalized discrimination and endorsements of negative racial/ethnic stereotypes and excess fat accumulation among ethnically heterogeneous samples of Blacks.

    The Aday-Andersen model was used as a framework for investigating the contribution of immigration status (i.e., nativity and acculturation), socioeconomic factors, health care access, health status, and health insurance to usual source of health care (USOC) in a nationally representative sample of African American (n=551) and Caribbean Black men (n=1,217). We used the 2001-2003 National Survey of American Life, a nationally representative household survey of non-institutionalized U.S. Blacks to conduct descriptive and logistic regression analyses. Older age, more health conditions, neighborhood medical clinic access, and health insurance were associated with higher odds of reporting a USOC. Odds were lower for men with lower-middle incomes and poorer mental health status. Having health insurance was associated with higher odds of reporting a USOC for African American men but lower odds among Caribbean Black men. Odds were higher in the presence of more health conditions for African American men than for Caribbean Black men. Health care reform policies aimed solely at increasing health insurance may not uniformly eliminate USOC disparities disfavoring U.S. and foreign-born non-Hispanic Black men.

    Acculturation to the UK diet may contribute to the increased burden of non-communicable diseases in Black British communities. The present study aimed to assess nutritional composition and the contribution that traditional foods make to dietary intake in a group of UK-residing Caribbean and West African adults and to explore differences according to ethnicity and duration of residence. Observational study. Dietary intake was assessed using multiple, standardised triple-pass 24 h recalls and analysed using a nutritional composition database. Associations between sociodemographic variables and duration of residence with dietary intake were assessed using ANCOVA. London, UK, October 2011-December 2012. UK adults of Caribbean (n 50) or West African (n 83) ancestry, aged 18-75 years. The Caribbean participants were older and more likely to be born in the UK. After adjusting for age, sex and ethnicity, those who had been resident in the UK for the longest duration had significantly higher intakes of energy (Ptraditional cultural foods compared with the Caribbean diet, which was more reliant on 'Westernised' foods such as sugar-sweetened beverages. These results are novel in demonstrating dietary acculturation in UK adults of Caribbean and West African ancestry. We have provided detailed data regarding the role of traditional foods, presenting dietary information that may guide in individualising care for patients from these communities and improve the cultural sensitivity of public health strategies.

    This study was aimed to investigate the main and buffering effects of positive religious coping on the association between the number of chronic medical conditions and major depressive disorder (MDD) among African Americans, Caribbean Blacks and Non-Hispanic Whites. This cross-sectional study used data from the National Survey of American Life, 2001 and 2003. This study enrolled 3,570 African Americans, 1,438 Caribbean Blacks and 891 Non-Hispanic Whites. Number of chronic conditions and positive religious coping were independent variables, 12-month MDD was the outcome and socio-economic characteristics were controls. We fitted the following three ethnic-specific logistic regressions for data analysis. In Model I, we included the number of chronic conditions and controls. In Model II, we added the main effect of religious coping. In Model III, we included an interaction between religious coping and number of chronic conditions. Based on Model I, number of chronic conditions was associated with higher odds of 12-month MDD among all race/ethnic groups. Model II showed a significant and negative association between religious coping and MDD among Caribbean Blacks (odds ratio [OR] =0.55, 95% confidence Interval [CI] =0.39-0.77), but not African Americans or Hispanic Whites. Model III suggested that, only among Caribbean Blacks, the effect of chronic medical conditions on MDD is smaller in the presence of high positive religious coping (OR for interaction = 0.73, 95% CI = 0.55-0.96). Although the association between multiple chronic conditions and MDD may exist regardless of race and ethnicity, race/ethnicity may shape how positive religious coping buffers this association. This finding sheds more light onto race and ethnic differences in protective effects of religiosity on mental health of populations.

    This study explores relationships between lifetime and 12 month DSM-IV major depressive disorder (MDD), depressive symptoms and involvement with family and friends within a national sample of African American and Black Caribbean adults (n=5,191). MDD was assessed using the DSM-IV World Mental Health Composite International Diagnostic Interview (WMH-CIDI) and depressive symptoms were assessed using the CES-D and the K6. Findings indicated that among both populations close supportive ties with family members and friends are associated with lower rates of depression and major depressive disorder. For African Americans, closeness to family members was important for both 12 month and lifetime MDD; and both family and friend closeness were important for depressive symptoms. For Caribbean Blacks, family closeness had more limited associations with outcomes and was directly associated with psychological distress only. Negative interactions with family (conflict, criticisms), however, were associated with higher MDD and depressive symptoms among both African Americans and Black Caribbeans. PMID:25594791

    Evidence suggests that black men are disproportionately more affected than any other ethnicity by prostate cancer. The aim of this review is to identify studies exploring black men of African and Caribbean descent, their fears of prostate cancer and their attitudes towards screening. Four databases were searched and reference lists of relevant papers were hand searched. The inclusion criteria were studies exploring attitudes towards screening and fear of prostate cancer in black men of African and Caribbean backgrounds, peer-reviewed research, qualitative studies, surveys, questionnaires and English language publications. Qualitative findings were synthesized using a thematic framework to which quantitative findings were integrated. Of the 16 papers, 10 were quantitative and 6 were qualitative, all of which were conducted in the United States of America. Poorer and less educated black men were reluctant to seek help for prostate cancer. They may not visit their doctors for fear of intrusion into their personal lives. Moreover, they were fearful of being emasculated as a result of the digital rectal examination. The review identifies a paucity of UK literature on black men's fears and perceptions of prostate cancer. Further studies are needed in the United Kingdom to address this gap in the literature. © The Author(s) 2018. Published by Oxford University Press. All rights reserved.

    There are well-established differences in optic nerve morphology between patients of African and European descent. Spectral domain optical coherence tomography (OCT) scanning has demonstrated these differences with respect to optic disc area (DA), average cup-disc ratio, cup volume, and nerve fiber layer thickness. However, the term "African descent" describes a heterogenous group with considerable variability. This study evaluates differences in optic nerve and retinal nerve fiber layer (RNFL) parameters as measured by Cirrus HD-OCT between Caribbean black and African American patients. A total of 25 African American subjects and 25 Caribbean black subjects with normal ocular examinations were consecutively recruited to this study. All patients received imaging of the optic nerve and nerve fiber layer with Cirrus HD-OCT. Optic nerve and RNFL parameters were evaluated for statistically significant differences using a t test. A mixed effect model for correlated data was then created to adjust outcome variables for (1) repeated measures and (2) optic nerve size. Two one-sided t tests were then utilized to determine equivalence. After adjustment for DA, RNFL thickness, cup volume, DA, inferior nerve fiber layer, and vertical cup-disc ratio demonstrated statistically significant equivalence between the 2 groups (P value fiber layer quadrant was significantly different between the 2 groups and may merit further investigation. Findings of this study suggest that optic nerve and RNFL morphology is markedly similar between Caribbean blacks and African Americans once adjusted for optic nerve size but cannot be considered equivalent in all measures, particularly in the superior nerve fiber layer.

    Full Text Available Abstract Background African American men have the highest prostate cancer morbidity and mortality rates than any other racial or ethnic group in the US. Although the overall incidence of and mortality from prostate cancer has been declining in White men since 1991, the decline in African American men lags behind White men. Of particular concern is the growing literature on the disproportionate burden of prostate cancer among other Black men of West African ancestry in the Caribbean Islands, United Kingdom and West Africa. This higher incidence of prostate cancer observed in populations of African descent may be attributed to the fact that these populations share ancestral genetic factors. To better understand the burden of prostate cancer among men of West African Ancestry, we conducted a review of the literature on prostate cancer incidence, prevalence, and mortality in the countries connected by the Transatlantic Slave Trade. Results Several published studies indicate high prostate cancer burden in Nigeria and Ghana. There was no published literature for the countries Benin, Gambia and Senegal that met our review criteria. Prostate cancer morbidity and/or mortality data from the Caribbean Islands and the United Kingdom also provided comparable or worse prostate cancer burden to that of US Blacks. Conclusion The growing literature on the disproportionate burden of prostate cancer among other Black men of West African ancestry follows the path of the Transatlantic Slave Trade. To better understand and address the global prostate cancer disparities seen in Black men of West African ancestry, future studies should explore the genetic and environmental risk factors for prostate cancer among this group.

    This systematic literature review aims to identify diabetes self-management education (DSME) features to improve diabetes education for Black African/Caribbean and Hispanic/Latin American women with Type 2 diabetes mellitus. We conducted a literature search in six health databases for randomized controlled trials and comparative studies. Success rates of intervention features were calculated based on effectiveness in improving glycosolated hemoglobin (HbA1c), anthropometrics, physical activity, or diet outcomes. Calculations of rate differences assessed whether an intervention feature positively or negatively affected an outcome. From 13 studies included in our analysis, we identified 38 intervention features in relation to their success with an outcome. Five intervention features had positive rate differences across at least three outcomes: hospital-based interventions, group interventions, the use of situational problem-solving, frequent sessions, and incorporating dietitians as interventionists. Six intervention features had high positive rate differences (i.e. ≥50%) on specific outcomes. Different DSME intervention features may influence broad and specific self-management outcomes for women of African/Caribbean and Hispanic/Latin ethnicity. With the emphasis on patient-centered care, patients and care providers can consider options based on DSME intervention features for its broad and specific impact on outcomes to potentially make programming more effective.

    Full Text Available The paper results from a research project completed by the author in 1994 on the quality of language-learning environments in the Cape Town area . . Xhosa is now constitutionally enshrined as one of the eleven official languages of South Africa, and is the dominant language in Western Cape black townships. This paper questions the fruitfUlness of primary schools in black townships attempting to use English as the sole medium of instruction. The paper shows that in actual classroom situations the Ll (Xhosa is used as an aid to L2 (English medium instruction in the schools of Khayelitsha and Lagunya townships around Cape Town.

    Miller, Beverly A. King

    This grounded theory case study examines the experiences of Panamanian Afro-Caribbean women and their membership in STEM (Science, Technology, Engineering and Mathematics) training and careers. The shortage of Science and Math teachers in 48 of 50 States heightens the need for those trained in STEM. Females of African phenotype have persistently been underrepresented in STEM. However, this trend does not appear to have held for Panamanian Afro-Caribbean women. The current study explores issues related to STEM participation for these women by addressing the overarching question: What key factors from the lived experiences of Panamanian Afro-Caribbean women in STEM careers can be used to inform work with females of African phenotype in their pursuit of STEM education and STEM careers? Five women were identified for inclusion in the study's purposive sample. The study draws upon assertions and implications about the relevance of self-identity and collective-identity for membership in STEM. Data for the study was gathered through qualitative interviews, surveys, and observations. The grounded theory approach was used to analyze emergent themes related to participants' responses to the research questions. Two models, the STEM Attainment Model (SAM) and the Ecological Model of Self-Confidence and Bi-Directional Effect, are proposed from evaluation of the identified information. Socio-cultural values and learned strategies were determined to influence self-confidence which is identified as important for persistence in STEM training and careers for females of African phenotype. Evidence supports that the influences of parents, country of origin, neighborhood communities, schools and teachers are factors for persistence. Through the voices of these women, recommendations are offered to the gatekeepers of STEM academic pathways and ultimately STEM careers.

    Little is known about levels of physical fitness in children from different ethnic groups in the UK. We therefore studied physical fitness in UK children (aged 9-10 years) of South Asian, black African-Caribbean and white European origin. Cross-sectional study. Primary schools in the UK. 1625 children (aged 9-10 years) of South Asian, black African-Caribbean and white European origin in the UK studied between 2006 and 2007. A step test assessed submaximal physical fitness from which estimated VO2 max was derived. Ethnic differences in estimated VO2 max were estimated using multilevel linear regression allowing for clustering at school level and adjusting for age, sex and month as fixed effects. The study response rate was 63%. In adjusted analyses, boys had higher levels of estimated VO2 max than girls (mean difference 3.06 mL O2/min/kg, 95% CI 2.66 to 3.47, pfitness than white Europeans and black African-Caribbeans in the UK. This ethnic difference in physical fitness is at least partly explained by ethnic differences in physical activity. Published by the BMJ Publishing Group Limited.

    Full Text Available Abstract Background Black minority ethnic groups in the UK have relatively low rates of deceased donation and report a higher prevalence of beliefs that are regarded as barriers to donation. However there is little data from migrants' countries of origin. This paper examines community attitudes to deceased kidney donation in Barbados and compares the findings with a survey conducted in a disadvantaged multi-ethnic area of south London. Methods Questionnaires were administered at four public health centres in Barbados and at three private general practices. Adjusted odds ratios were calculated to compare attitudinal responses with a prior survey of 328 Caribbean and 808 White respondents in south London. Results Questionnaires were completed by 327 respondents in Barbados (93% response; 42% men and 58% women, with a mean age of 40.4 years (SD 12.6. The main religious groups were Anglican (29% and Pentecostal (24%. Educational levels ranged from 18% not completing 5th form to 12% with university education. Attitudes to the notion of organ donation were favourable, with 73% willing to donate their kidneys after their death and only 5% definitely against this. Most preferred an opt-in system of donation. Responses to nine attitudinal questions identified 18% as having no concerns and 9% as having 4 or more concerns. The highest level of concern (43% was for lack of confidence that medical teams would try as hard to save the life of a person who has agreed to donate organs. There was no significant association between age, gender, education or religion and attitudinal barriers, but greater knowledge of donation had some positive effect on attitudes. Comparison of attitudes to donation in south London and Barbados (adjusting for gender, age, level of education, employment status indicated that a significantly higher proportion of the south London Caribbean respondents identified attitudinal barriers to donation.

    Abstract African, Caribbean, and Black (ACB) women are greatly overrepresented in new HIV infections in comparison with Canada's general population. Social and structural factors such as HIV-related stigma, gender discrimination, and racial discrimination converge to increase vulnerability to HIV infection among ACB women by reducing access to HIV prevention services. Stigma and discrimination also present barriers to treatment, care, and support and may contribute to mental health problems. We administered a cross-sectional survey to HIV-positive ACB women (n=173) across Ontario in order to examine the relationships between HIV-related stigma, gender discrimination, racial discrimination, and depression. One-third of participants reported moderate/severe depression scores using the Beck Depression Inventory Fast-Screen guidelines. Hierarchical block regression, moderation, and mediation analyses were conducted to measure associations between independent (HIV-related stigma, gender discrimination, racial discrimination), moderator/mediator (social support, resilient coping), and dependent (depression) variables. Findings included: (1) HIV-related stigma was associated with increased depression; (2) resilient coping was associated with reduced depression but did not moderate the influence of HIV-related stigma on depression; and (3) the effects of HIV-related stigma on depression were partially mediated through resilient coping. HIV-related stigma, gender discrimination, and racial discrimination were significantly correlated with one another and with depression, highlighting the salience of examining multiple intersecting forms of stigma. Generalizability of findings may be limited due to nonrandom sampling. Findings emphasize the importance of multi-component interventions, including building resilient coping skills, mental health promotion and assessment, and stigma reduction programs.

    Full Text Available Adie's tonic pupil, though well known in literature is a rarity in practice. Few case reports have mentioned the occurrence of Adie's pupil during a migraine attack. We report a young female with a history of migraine without aura presenting with asymmetric pupils during migraine attack. Her right pupil was dilated, unresponsive to light with poor response to near reflex. She also had a bilateral loss of ankle jerks. In 0.125% pilocarpine test, the affected pupil responded significantly, and Holmes Adie's syndrome was diagnosed. The patient remained asymptomatic after adjustment of refraction of the right eye for the near vision. It is usually a benign condition. Early clinical detection of such condition is necessary to prevent unnecessary and costly investigations as well to reassure the patient.

    Full Text Available BACKGROUND: Bioelectrical impedance analysis (BIA is a potentially valuable method for assessing lean mass and body fat levels in children from different ethnic groups. We examined the need for ethnic- and gender-specific equations for estimating fat free mass (FFM from BIA in children from different ethnic groups and examined their effects on the assessment of ethnic differences in body fat. METHODS: Cross-sectional study of children aged 8-10 years in London Primary schools including 325 South Asians, 250 black African-Caribbeans and 289 white Europeans with measurements of height, weight and arm-leg impedance (Z; Bodystat 1500. Total body water was estimated from deuterium dilution and converted to FFM. Multilevel models were used to derive three types of equation {A: FFM = linear combination(height+weight+Z; B: FFM = linear combination(height(2/Z; C: FFM = linear combination(height(2/Z+weight}. RESULTS: Ethnicity and gender were important predictors of FFM and improved model fit in all equations. The models of best fit were ethnicity and gender specific versions of equation A, followed by equation C; these provided accurate assessments of ethnic differences in FFM and FM. In contrast, the use of generic equations led to underestimation of both the negative South Asian-white European FFM difference and the positive black African-Caribbean-white European FFM difference (by 0.53 kg and by 0.73 kg respectively for equation A. The use of generic equations underestimated the positive South Asian-white European difference in fat mass (FM and overestimated the positive black African-Caribbean-white European difference in FM (by 4.7% and 10.1% respectively for equation A. Consistent results were observed when the equations were applied to a large external data set. CONCLUSIONS: Ethnic- and gender-specific equations for predicting FFM from BIA provide better estimates of ethnic differences in FFM and FM in children, while generic equations

    2014-01-01

    This investigation among Afro-Caribbean adults in the United States Virgin Islands (USVI) examined whether acculturation and preference for dining out accounted for variation by nativity in the frequency of fast food restaurant use, and assessed the relationship of fast food restaurant use to body weight and insulin resistance. A randomly selected sample of 679 Afro-Caribbean adults (aged ≥ 20 years), including 436 who were foreign-born and 243 who were native-born, were recruited on the island of St. Croix, USVI. Information on demographic characteristics, level of acculturation and dietary practices were obtained from participants by questionnaire. Fasting blood samples, which were measured for glucose and insulin, and anthropometric measurements were also collected from participants. Insulin resistance was estimated by the homeostasis model assessment (HOMA). Relationships between variables were assessed with analysis of variance and logistic regression analyses. In bivariate analyses, birth in the USVI, younger age, being single, greater preference for dining out and higher levels of education and acculturation were significantly (P fast food restaurant use. In multivariate logistic regression analyses, birth in the USVI, younger age and preference for dining out were independently associated with frequent (≥ 2 days/week) fast food restaurant use. The mean level of HOMA insulin resistance among participants increased significantly with more frequent use of fast food restaurants. Among Afro-Caribbean adults in the USVI, fast food restaurant use is positively associated with insulin resistance and varies by nativity, but acculturation does not account for this variation.

    The purpose of this study was to determine whether baseline pupil size and pupil responses during visual scanning with eye-tracking technology could discriminate children with autism spectrum disorder (ASD) from mental age-matched and chronological age-matched controls. To this end, we used stimuli consisting in still color photographs presented centrally to the participant's midline on a stimulus monitor. Each child was presented with a series of neutral faces, virtual faces (avatars) and different objects, separated by black slides. We recorded the mean pupil size and pupil size changes over time in each of the three categories of stimuli and during exposure to the black slides. Fifty-seven children participated in study (19 ASD, mean age 118 months; 19 mental age-matched controls, mean age 87 months; and 19 chronological age-matched controls, mean age 118 months). We compared the baseline pupil size and pupil responses during visual scanning among the three diagnostic groups. During the presentation of slides, the mean pupil size in the ASD group was clearly smaller than in the MA-matched and CA-matched groups. Discriminate analysis of pupil size during the presentation of black slides and slides with visual stimuli successfully predicted group membership in 72% of the participants. Group membership was correctly classified in 89% of the participants in the ASD group, in 63% in the MA-matched group and in 63% in the CA-matched group. These potential biomarkers may contribute to our understanding of the differences in neurological development in the brain in autism and could prove useful as indicators of ASD.

    With the 2011 educational reform in France, a new course has been created in secondary schools : Methods & Practices in Science (MPS). The main goal was to improve the pupils working methods in science, including laboratory and field works. In addition, the pedagogy develops pupils autonomy and creativity, a key factor in a research process. Three teachers are working together (Mathematics, Physics and Geology-Biology), showing how different disciplines complement one another. Eventually, this is aimed at attracting more students in scientific sections. This course is optional, in the "seconde" class in French secondary schools (i.e., for 15 years old students). For the next class, they will have to choose between scientific, economic and literature sections : it is a useful option for them to decide which section has their preference. In my high-school in Clermont-Ferrand, we have chosen a research subject on hydrogeology & water quality improvement in region "Auvergne". The pupils will have to develop and set up appropriate tools to check and improve the water quality, related to different disciplines : - Geology & Biology: hydrogeology, effects of different pollutants on aquatic life, solutions to improve water quality (example of the natural water treatment zone in the lake of "Aydat, Auvergne, France"). - Physics & Chemistry: water potability criteria, pollution tests in water, water treatment plants working. - Mathematics: algorithm development, modeling on excel of the dispersion of pollutants The pedagogy of this course is new in French high-schools : pupils work in groups of three, so as to develop cooperation and autonomy. The teachers give the guidelines at the beginning of each working session, and answer the students questions when necessary. The evaluation is competence-based : instead of a mark, which is the main evaluation method in France, the pupils have to evaluate their own skills. Then, the teachers make an evaluation, and the global process is

Author discusses 2 reports from 2005 on present developments problems in the Caribbean region: the economics-focussed 'A time to choose: Caribbean development in the 21st century' by the World Bank, and the UN ECLAC report 'The Millennium Development Goals: a Latin American and Caribbean perspective', with a broader, also social and political, development agenda. He relates what both reports recommend for the Caribbean on the basis of their evaluations of past development. The World Bank report advocates a move toward the services sector, including tourism, offshore education, ICT services, and health services as most viable. The ECLAC report notes some social and political advances in comparison to other developing countries, but also remaining problems and inequalities. The author finds that the World Bank report's neoliberal, one-size-fits-all approach is not mindful of specific Caribbean realities, while the ECLAC study is more sensitive to local realities, and espouses a mixed economy. He thus considers the ECLAC approach preferable, but argues that it needs to go further, as it excludes Cuba and Haiti as atypical states.

    The idea of this project is to put pupils in a teaching situation. Classes of teenagers go to primary schools and animate a science workshop. Junior pupils are separated in small groups and they attend two different sessions in the same half-day. The whole workshop consists of 4 sessions. Each session is organized with an activity (microscope observation, counting of chromosomes, drawing of a curve, etc.) in which senior pupils coach the younger, and ends with a debate or an assessment. The first experiment of this type of project was realized with a class of 14 to 15 year old pupils on the theme: How do your parents transmit your characteristics? The four sessions are attended in disorder but when knowledge of other sessions are necessary, senior pupils explain them at the beginning of the session. Junior pupils have a notebook to write their activities and to note their conclusions. Session 1: What did my father give to make me? Drawing and measuring microscopic observations of human spermatozoons. Conclusion: my father gave a spermatozoon which measures less than one mm long, this spermatozoon met my mother's egg and it made my first cell. Session 2: What does the program that made me look like? Microscope observation of blood cells, identification of chromosomes in the core. On microscope pictures, counting of chromosomes. Conclusion: My program is in each cell of my body, inside the core. Sometimes, in this core, we can observe short sticks that are called chromosomes. All human beings have the same number of chromosomes in their cells: 46. Session 3: Where do my chromosomes come from? Counting of chromosomes in spermatozoons or ovums and playing with sets of chromosomes to deduct sex of a baby. Conclusion: Daddy gave me 23 chromosomes and mummy gave me 23 chromosomes too. My program is then constituted from half of daddy's program and half of mummy's program. My brothers and sisters also have half and half, but not the same halves! Session 4: Where is the

    Seldom studies are available on trends in stroke incidence in blacks. We aimed to evaluate whether stroke risk prevention policies modified first-ever stroke incidence and outcomes in the black Afro-Caribbean population of Martinique. Etude Réalisée en Martinique et Centrée sur l'Incidence des Accidents Vasculaires Cérébraux (ERMANCIA) I and II are 2 sequential prospective population-based epidemiological studies. There have assessed temporal trends in first-ever stroke incidence, risk factors, pathological types, and early outcomes in the black Afro-Caribbean population of Martinique comparing two 12-month periods (1998-1999 and 2011-2012). Crude and age-standardized incidence and 30-day outcomes for stroke in the 2 study periods were compared using Poisson regression. We identified 580 and 544 first-ever strokes in the 2 studies. World age-standardized incidence rates decreased by 30.6% in overall (111 [95% confidence interval, 102-120] versus 77 [95% confidence interval, 70-84]). Rate decline was greater in women than in men (34% versus 26%) particularly in women aged 65 to 74 years (-69%) and 75 to 84 years (-43%). Frequencies of hypertension and diabetes mellitus were unchanged, whereas dyslipidemia, smoking, and atrial fibrillation significantly increased. Only ischemic stroke types showed significant rate reduction in overall and in women, incidence rate ratio (95% confidence intervals) of 0.69 (0.50-0.97) and 0.61 (0.42-0.88), respectively. The overall 30-day case-fatality ratio remained stable (19.3%/17.6%), whereas a better 30-day outcome was found (modified Rankin Score, ≤2 in 47%/37.6%; P=0.03). Over 13 years, there has been a significant decrease (30.6%) in the age-specific first-ever stroke incidence in our Afro-Carribean population. Although prevention policies seem effective, we need to focus on new risk factors limitation and on male population adherence to prevention program. © 2014 American Heart Association, Inc.

  3. On written expression of primary school pupils

    Full Text Available Normative rules of standard Serbian language are acquired during primary and secondary education through curriculum demands of Serbian language instruction, which takes place in three fields: grammar, orthography and culture of expression. Topic of interest in this paper is the quality of written expression of 6th and 7th grade pupils, in the context of all three fields specified to be mastered by the curriculum of Serbian language. Research comprised 148 primary school pupils from Belgrade. Linguistic analysis of spontaneously created written text was performed, in the conditions where it was not explicitly demanded form the pupil to write correctly. The results indicate that the majority of pupils make spelling and grammatical errors, meeting the condition for the basic level of mastering the knowledge in Serbian language according to the standards specified for the end of compulsory education. In addition to this, a considerable majority of pupils has a satisfactory level of culture of written expression. Pupils more often make spelling than grammatical errors. Seventh grade pupils are better than sixth grade pupils with respect to adhering to grammar rules and according to culture of written expression, while the mark in Serbian language and general school achievement of pupils correlate only with the degree of adhering to the orthographic rules. It was concluded that not only individual programs of support for pupils who make more errors are necessary, but also launching national projects for the development of linguistic competence of the young in Serbia.

    Lower rates of substance abuse are found among Black Americans compared to Whites, but little is known about differences in substance abuse across ethnic groups within the black population. We examined prevalence rates of substance abuse among Blacks across three geographic regions (US, Jamaica, Guyana). The study also sought to ascertain whether length of time, national context and major depressive episodes (MDE) were associated with substance abuse. We utilized three different data sources based upon probability samples collected in three different countries. The samples included 3,570 African Americans and 1,621 US Caribbean Black adults from the 2001-2003 National Survey of American Life (NSAL). An additional 1,142 Guyanese Blacks and 1,176 Jamaican Blacks living in the Caribbean region were included from the 2005 NSAL replication extension study, Family Connections Across Generations and Nations (FCGN). Mental disorders were based upon DSM-IV criteria. For the analysis, we used descriptive statistics, chi-square, and multivariate logistic regression analytic procedures. Prevalence of substance abuse varied by national context, with higher rates among Blacks within the United States compared to the Caribbean region. Rates of substance abuse were lower overall for women, but differ across cohorts by nativity and length of time in the United States, and in association with major depressive episode. The study highlights the need for further examination of how substance abuse disparities between US-based and Caribbean-based populations may become manifested.

    Over the past 500 years almost 100 tsunamis have been observed in the Caribbean and Western Atlantic, with at least 3510 people having lost their lives to this hazard since 1842. Furthermore, with the dramatic increase in population and infrastructure along the Caribbean coasts, today, millions of coastal residents, workers and visitors are vulnerable to tsunamis. The UNESCO IOC Intergovernmental Coordination Group for Tsunamis and other Coastal Hazards for the Caribbean and Adjacent Regions (CARIBE EWS) was established in 2005 to coordinate and advance the regional tsunami warning system. The CARIBE EWS focuses on four areas/working groups: (1) Monitoring and Warning, (2) Hazard and Risk Assessment, (3) Communication and (4) Education, Preparedness and Readiness. The sea level monitoring component is under Working Group 1. Although in the current system, it's the seismic data and information that generate the initial tsunami bulletins, it is the data from deep ocean buoys (DARTS) and the coastal sea level gauges that are critical for the actual detection and forecasting of tsunamis impact. Despite multiple efforts and investments in the installation of sea level stations in the region, in 2004 there were only a handful of sea level stations operational in the region (Puerto Rico, US Virgin Islands, Bermuda, Bahamas). Over the past 5 years there has been a steady increase in the number of stations operating in the Caribbean region. As of mid 2012 there were 7 DARTS and 37 coastal gauges with additional ones being installed or funded. In order to reach the goal of 100 operational coastal sea level stations in the Caribbean, the CARIBE EWS recognizes also the importance of maintaining the current stations. For this, a trained workforce in the region for the installation, operation and data analysis and quality control is considered to be critical. Since 2008, three training courses have been offered to the sea level station operators and data analysts. Other

In spite of the assumption that Holocaust denial amongst the youth in Slovenia already exists, we also assumed that a degree of Holocaust denial amongs Slovenian pupils is lower that amongst their peers in other EU countries. Research also inquired about the level of anti-Semitism in conjunction with Holocaust denial. The research project confirmed that students on lower levels of high school education and with less history and sociology lessons in curriculum are more receptive for the Holocaust denial and anti-Semitism is more present in this demographic. The level of Holocaust denial amongst secondary school pupils is not negligible; it suggests that this topic should be more thoroughly discussed in secondary schools.

    The aberrations of axisymmetric imaging systems can be calculated to third order by use of the Seidel formula. The Coddington equations give aberrations that have quadratic dependence on the pupil, for all field points. The pupil astigmatism conditions were recently developed to predict and control aberrations that have quadratic field dependence and arbitrary pupil dependence. We investigate the relationship between the exact pupil astigmatism conditions and the classical Seidel treatment of pupil aberration.

    2015-06-01

    We explored whether object behavioral priming and pupil changes occur in the absence of recognition memory. Experiment 1 found behavioral priming for unrecognized objects (Ms) regardless of whether they had been encoded perceptually or conceptually. Using the same perceptual encoding task, Experiment 2 showed greater pupil dilation for Ms than for correct rejections of unstudied objects (CRs) when reaction times were matched. In Experiment 3, there was relatively less pupil dilation for Ms than for similarly matched CRs when objects had been encoded conceptually. Mean/peak pupil dilation for CRs, but not Ms, increased in Experiment 3, in which novelty expectation was also reduced, and the pupillary time course for both Ms and CRs was distinct in the two experiments. These findings indicate that both behavioral and pupil memory occur for studied, but unrecognized stimuli, and suggest that encoding and novelty expectation modulate pupillary memory responses. © 2015 Society for Psychophysiological Research.

The first is an anthology that tries to build on Mintz’s ideas – as I will argue below, in a circumspect and not fully convincing way. In the second Mintz describes and compares the societies of Jamaica, Haiti, and Puerto Rico, and looks back on his work that started in the 1940s.

    Full Text Available This study compares the health conditions of domestic Caribbeans with those living in the United States to explore how national context and migration experiences might influence substance use (i.e., alcohol or drug and other mental and physical health conditions. The study is based upon probability samples of non-institutionalized Caribbeans living in the United States (1621, Jamaica (1216 and Guyana (2068 18 years of age and over. Employing descriptive statistics and multivariate analytic procedures, the results revealed that substance use and other physical health conditions and major depressive disorder and mania vary by national context, with higher rates among Caribbeans living in the United States. Context and generation status influenced health outcomes. Among first generation black Caribbeans, residing in the United States for a longer length of time is linked to poorer health outcomes. There were different socio-demographic correlates of health among at-home and abroad Caribbeans. The results of this study support the need for additional research to explain how national context, migratory experiences and generation status contribute to understanding substance use and mental disorders and physical health outcomes among Caribbean first generation and descendants within the United States, compared to those remaining in the Caribbean region.

    2011-01-01

    Full Text Available This paper reports findings from a study among 610 Year 7 (typically age 12 pupils at 27 nonselective secondary schools in three English regions: Cornwall and Devon, London, and Greater Manchester. Data was gathered in workshops, each with 15–25 pupils, who completed questionnaires and performed individual tasks, all related to their vocational and educational aims, their ideas on what counted as success, and the main influences on their forward thinking, then discussed their answers and results. The discussions were tape recorded. Most pupils expressed robust occupational aims, and most said that they wanted to go to university. Family class did not predict levels of educational or occupational aims, but was related to the importance attached to “the job that I want to do” in the pupils' forward thinking. SAT scores did predict levels of occupational aspiration, ideas on what counted as success, and by whom and what the pupils were most influenced. These findings are interpreted to challenge the view, on which a raft of current policies are based, that social class disparities in educational and labour market outcomes are due to the intergenerational transmission of low aspirations in lower-class families and neighbourhoods. The paper concludes with an alternative model of status transmission processes in which attainments during secondary education are posited as the key intervening variable.

  14. Cognitive and Ocular Factors Jointly Determine Pupil Responses under Equiluminance.

    Directory of Open Access Journals (Sweden)

    Tomas Knapen

    Full Text Available Changes in pupil diameter can reflect high-level cognitive signals that depend on central neuromodulatory mechanisms. However, brain mechanisms that adjust pupil size are also exquisitely sensitive to changes in luminance and other events that would be considered a nuisance in cognitive experiments recording pupil size. We implemented a simple auditory experiment involving no changes in visual stimulation. Using finite impulse-response fitting we found pupil responses triggered by different types of events. Among these are pupil responses to auditory events and associated surprise: cognitive effects. However, these cognitive responses were overshadowed by pupil responses associated with blinks and eye movements, both inevitable nuisance factors that lead to changes in effective luminance. Of note, these latter pupil responses were not recording artifacts caused by blinks and eye movements, but endogenous pupil responses that occurred in the wake of these events. Furthermore, we identified slow (tonic changes in pupil size that differentially influenced faster (phasic pupil responses. Fitting all pupil responses using gamma functions, we provide accurate characterisations of cognitive and non-cognitive response shapes, and quantify each response's dependence on tonic pupil size. These results allow us to create a set of recommendations for pupil size analysis in cognitive neuroscience, which we have implemented in freely available software.

In vivo imaging of the human photoreceptor mosaic at 0.5 and 10° from fixation indicates that the use of an annular illumination pupil and a circular imaging pupil provides the most benefit of all configurations when using a one Airy disk diameter pinhole, in agreement with the paraxial confocal microscopy theory. Annular illumination pupils with 0.26 and 0.39 normalized inner radii performed best in terms of the narrowing of the autocorrelation central lobe (between 7 and 12%), and the increase in manual and automated photoreceptor counts (8 to 20% more cones and 11 to 29% more rods). It was observed that the use of annular pupils with large inner radii can result in multi-modal cone photoreceptor intensity profiles. The effect of the annular masks on the average photoreceptor intensity is consistent with the Stiles-Crawford effect (SCE). This indicates that combinations of images of the same photoreceptors with different apodization configurations and/or annular masks can be used to distinguish cones from rods, even when the former have complex multi-modal intensity profiles. In addition to narrowing the point spread function transversally, the use of annular apodizing masks also elongates it axially, a fact that can be used for extending the depth of focus of techniques such as adaptive optics optical coherence tomography (AOOCT). Finally, the positive results from this work suggest that annular pupil apodization could be used in refractive or catadioptric adaptive optics ophthalmoscopes to mitigate undesired back-reflections.

    This study aimed to investigate the association between obesity and major depression disorder (MDD) in a nationally representative sample of Black adolescents in the USA. The study also tested the effects of ethnicity and gender as possible moderators. Data came from the National Survey of American Life (NSAL)-Adolescents, a representative household mental health survey of Black adolescents in the USA. Participants consisted of 1170 Black adolescents (810 African Americans and 360 Caribbean Blacks). Obesity was defined determined by the cutoff points based on the body mass index (BMI) appropriate for age and gender. Twelve-month MDD was measured using the World Mental Health Composite International Diagnostic Interview (CIDI). In the first step, the association between obesity and MDD in the pooled sample, controlling for the main effects of gender and ethnicity. In the next steps, two interactions were tested: (1) obesity and ethnicity and (2) obesity and gender. Although any associations between obesity and MDD in the pooled sample of Blacks were not found, there was a significant interaction between ethnicity and obesity on MDD. Upon testing the associations across intersections of ethnicity and gender, a positive association was found among Caribbean Black females but not Caribbean Black males, African American males, or African American female. The link between BMI and MDD among Blacks depends on ethnicity and gender, and risk of comorbid depression among Black youth with obesity is highest among Caribbean Black females.

    Abstract Background  Advocacy has a critical role to play in addressing concerns about access to appropriate mental health care and treatment for African and Caribbean men. Aim  To investigate good practice principles and organizational models for mental health advocacy provision for African and Caribbean men. Study design  The study consisted of: (i) A systematic literature review. Bibliographic and internet searching was undertaken from 1994 to 2006. The inclusion criteria related to mental health, advocacy provision for African and Caribbean men. (ii) Four focus groups with African and Caribbean men to explore needs for and experiences of mental health advocacy. (iii) An investigation into current advocacy provision through a survey of advocacy provision in England, Wales and Northern Ireland. (iv) Twenty‐two qualitative stakeholder interviews to investigate the operation of mental health advocacy for this client group. The study was undertaken in partnership with two service user‐led organizations and an African Caribbean mental health service. Results  Primary research in this area is scant. Mainstream mental health advocacy services are often poor at providing appropriate services. Services developed by the Black Community and voluntary sector are grounded in different conceptualizations of advocacy and sharper understanding of the needs of African and Caribbean men. The lack of sustainable funding for these organizations is a major barrier to the development of high‐quality advocacy for this group, reflecting a lack of understanding about their distinctive role. Conclusions  The commissioning and provision of mental health advocacy needs to recognize the distinct experiences of African and Caribbean men and develop capacity in the range of organizations to ensure equitable access.

    To determine the impact of doctors' communication style and doctor-patient race concordance on UK African-Caribbeans' comfort in disclosing depression. 160 African-Caribbean and 160 white British subjects, stratified by gender and history of depression, participated in simulated depression consultations with video-recorded doctors. Doctors were stratified by black or white race, gender and a high (HPC) or low patient-centred (LPC) communication style, giving a full 2×2×2 factorial design. Afterwards, participants rated aspects of doctors' communication style, their comfort in disclosing depression and treatment preferences Race concordance had no impact on African-Caribbeans' comfort in disclosing depression. However a HPC versus LPC communication style made them significantly more positive about their interactions with doctors (p=0.000), their overall comfort (p=0.003), their comfort in disclosing their emotional state (p=0.001), and about considering talking therapy (p=0.01); but less positive about considering antidepressant medication (p=0.01). Doctors' communication style was shown to be more important than patient race or race concordance in influencing African Caribbeans' depression consultation experiences. Changing doctors' communication style may help reduce disparities in depression care. Practitioners should cultivate a HPC style to make African-Caribbeans more comfortable when disclosing depression, so that it is less likely to be missed. Copyright © 2015 The Authors.

In this issue we focus on Brian Meeks's, Envisioning Caribbean Futures. Those invited to comment on the book are Jay Mandle and Rivke Jaffe. [First paragraph] In Envisioning Caribbean Futures: Jamaican Perspectives (2007, Brian Meeks writes “in sympathy with the new social movements that have evolved in the past decade which assert boldly that ‘another world is possible’” (p. 2. His effort is “to explore the horizons for different approaches to social living in Jamaica and the Caribbean in the twenty-first century” (p. 2. In this, he “seeks to move beyond a statement of general principles to propose specific alternatives” in order to “stimulate a conversation that looks beyond the horizon of policy confines, yet is not so far removed as to appear hopelessly utopian” (p. 3. My hope with this essay is to advance that conversation, in the first place by reviewing and assessing Meeks’s contribution and then by extending the discussion to the role that Jamaica’s diaspora (and by extension that of the region’s generally might play in moving the country, as Meeks puts it, from its current “state of crime and murder, and the broad undermining of the rule of law that pervades the society” (p. 71.

    An objective lens includes multiple optical elements disposed between a first end and a second end, each optical element oriented along an optical axis. Each optical surface of the multiple optical elements provides an angle of incidence to a marginal ray that is above a minimum threshold angle. This threshold angle minimizes pupil ghosts that may enter an interferometer. The objective lens also optimizes wavefront delivery and pupil imaging onto an optical surface under test.

    Secondary school can be a stressful period for adolescents, having to cope with many life changes. Very little research has been conducted on the mental health status of secondary school pupils in South East Asian countries, such as Vietnam.The study aimed to explore perceptions of mental health status, risk factors for mental health problems and strategies to improve mental health among Vietnamese secondary school students. A qualitative design was used to address the main study question including: six in-depth interviews conducted with professionals (with two researchers, two psychiatrists, and two secondary school teachers) to learn about their experience of mental health problems among secondary school pupils; 13 focus group discussions (four with teachers, four with parents, and five with pupils); and 10 individual in-depth interviews with pupils who did not take part in the FGDs, to reflect on the collected data and to deepen the authors' understanding. All interviews and FGDs were audio-taped, transcribed and analyzed for the identification of emerging issues using qualitative techniques of progressive coding, analytic memoing and ongoing comparison. Our study confirms the need to pay attention to mental health of pupils in Vietnam. Depression, anxiety, stress, suicidal thoughts and suicide attempts were seen as major problems by all stakeholders. Mental health problems were mainly associated with academic pressure, resulting from an overloaded curriculum and pressure from teachers and parents to succeed. The study found that pupils' mental health demands interventions at many levels, including at the level of government (Ministry of Education and Training), schools, communities, families and pupils themselves. Vietnamese secondary school pupils feel that their mental health status is poor, because of many risk factors in their learning and living environment. The need now is to investigate further to identify and apply strategies to improve students' mental

    2014-01-01

    Full Text Available The aim of the research is to demonstrate the junior pupils' skills development in still life drawing. Being related to the child's cognitive abilities, well-developed linear space perception positively affects the personality and readiness for various activities. Therefore, pupils' acquaintance with the basics of still life drawing in arts classes has both the aesthetic and psychological and intellectual benefits.Methodology is based on the analysis of theoretical concepts of art criticism, psychological and pedagogical works on developing artistic and creative skills of junior pupils, along with the teaching problems of picturing the space in still life drawings. The author carried out the research and experimental work in the Omsk comprehensive schools to identify the age evolution of children's still life drawings.The research results denote the following development stages of junior pupils' skills related to still life picturing: the first stage – still life objects are aligned to the lower paper edge; the second stage – objects are placed on a horizontal line above the lower paper edge, the object plane being parallel to it; the third stage – still life objects are aligned to a single line with the spatial representations of the object planes pictured as a slightly inclined line dividing the paper below the middle of the sheet; the fourth stage – objects are pictured on different heights (above or below each other, the object plane is pictured with two lines reflecting the perspective; the fifth stage – still life objects are pictured on different heights, object overlapping being common and the perspective reflection of the object planes pictured with two or three lines; the sixth stage – objects are placed on different levels, overlapping being obligatory and a multilevel object planes possible.Scientific novelty implies a systematic analysis, description and illustration of development stages of space picturing in children

    2004-12-01

    The tsunami problem for the coast of the Caribbean basin is discussed. Briefly the historical data of tsunami in the Caribbean Sea are presented. Numerical simulation of potential tsunamis in the Caribbean Sea is performed in the framework of the nonlinear-shallow theory. The tsunami wave height distribution along the Caribbean Coast is computed. These results are used to estimate the far-field tsunami potential of various coastal locations in the Caribbean Sea. In fact, five zones with tsunami low risk are selected basing on prognostic computations, they are: the bay "Golfo de Batabano" and the coast of province "Ciego de Avila" in Cuba, the Nicaraguan Coast (between Bluefields and Puerto Cabezas), the border between Mexico and Belize, the bay "Golfo de Venezuela" in Venezuela. The analysis of historical data confirms that there was no tsunami in the selected zones. Also, the wave attenuation in the Caribbean Sea is investigated; in fact, wave amplitude decreases in an order if the tsunami source is located on the distance up to 1000 km from the coastal location. Both factors wave attenuation and wave height distribution should be taken into account in the planned warning system for the Caribbean Sea.

    Hickling, F W; Hutchinson, G

    2012-07-01

    The intellectual exploration of phenomenological and psychiatric discovery that has flowered in the Caribbean in the period of political independence from British colonization is a reflection of the scholarship that has emerged from the academic nurturance by The University of the West Indies. Burgeoning migration of Caribbean people to England in the twentieth century has resulted in high reported rates of psychosis for this migrant population. Caribbean research into this condition has revealed that there exist hostile racial and environmental challenges in Britain that have had a profound pathological effect on the mental health of African Caribbean migrants. These findings have significantly shifted the pendulum of understanding of the aetiology of this condition from a genetic to a biopsychosocial position. Research has also revealed longstanding psychopathological effects of slavery and colonialism in the Caribbean that have had significantly negative long term effects on the mental health of many within the Caribbean population. Current research suggests that there is a need to nurture protective strategies to enhance resilience and social capital, which would ensure the wellness and continued survival of Caribbean people in spite of the many challenges they face.

    Full Text Available The main purpose of our study was to investigate how basic school pupils and teachers perceive and understand bullying. The participants in the study were 58 teachers and 396 pupils in basic school. The results indicate that both teachers and pupils perceive verbal bullying as the most frequent form of bullying compared to physical and relational bullying. Pupils report perceiving more bullying than teachers. Both pupils and teachers perceive physical and verbal bullying as more serious forms of bullying compared to relational bullying and report feeling more empathy toward victims of these two forms of bullying. In addition, teachers report that they are more willing to intervene in cases of physical and verbal bullying. There are significant differences between pupils’ and teachers’ reports of the likelihood of teachers’ interventions in cases of bullying; compared to pupils teachers report a higher likelihood of their intervention..

    In Talnet-we create new opportunities for gifted pupils in science. We suppose any level of giftedness or interest must have practical opportunities to be found and developed. We focus on study, research, inquiry, collaborative and modeling activities where the learning itself is not a primary goal. The activities combine online with face to face and are designed for 13-19 years old pupils. More than 1,000 pupils has participated in 28 different yearlong courses, more then 500 pupils in tens of different "T-excursions" and collaborative research activities. Gifted pupils involved such systemic and authentic activities can play an important role on the pupils' side of communication with "physics".

    The purpose of this study was to quantify how school sanitation conditions are associated with pupils' use of sanitation facilities. We conducted a longitudinal assessment in 60 primary schools in Nyanza Province, Kenya, using structured observations to measure facility conditions and pupils' use at specific facilities. We used multivariable mixed regression models to characterize how pupil to toilet ratio was associated with toilet use at the school-level and also how facility conditions were associated with pupils' use at specific facilities. We found a piecewise linear relationship between decreasing pupil to toilet ratio and increasing pupil toilet use (p toilet use and newer facility age (p toilets in a facility (p toilet use patterns, potentially leading to a better allocation of resources for school sanitation, and to improved health and educational outcomes for children.

    The relatively poor health of Black American people in the US and Black Caribbean people in England is a consistent finding in the health inequalities literature. Indeed, there are many similarities between the health, social, economic and demographic profiles of these two groups. However, there is evidence that Caribbean people in the US are faring considerably better. This paper explores differences in the social and economic position of Black American, Black Caribbean and white people in the US and Black Caribbean and white people in England, how these relate to ethnic inequalities in health, and may be underpinned by differences in patterns and contexts of migration. We use similar surveys from the US and England to explore these questions. The US data were drawn from the National Survey of American Life and the English data were drawn from the Health Survey for England and a follow up study. Findings show the advantaged health position of Caribbean American people in comparison with both Caribbean people in England and Black American people. Multivariate analyses indicate that these differences, and the differences in health between Black and white people in the two countries, are a consequence of social and economic inequalities.

    Full Text Available The presented text shows the results of research carried out within the dissertation thesis. The main topic is the phenomenon of sociocultural handicap of foreign pupils (pupils with a different mother tongue. The research is based on the expert belief that integration of foreign pupils (pupils with a different mother tongue into Czech schools and the training of teachers in this field is still somewhat marginal, even though there is a growing debate about increasing cultural diversity, increasing heterogeneity of schools and introduction of inclusive measures. The aim of the research was to analyze professional training of teachers in relation to the sociocultural handicap of foreign pupils (pupils with a different mother tongue. The goal was refined by the formulation of research questions: What possible problems (difficulties reflect teachers in the teaching process of foreign pupils? What procedures and strategies do teachers use to help these pupils to be integrated successfully? How do teachers assess their professional readiness for education of foreign pupils (whether they were sufficiently prepared to work with foreign pupils in the course of their undergraduate studies, where they find benefits, deficiencies in this training? How do students assess their undergraduate education for foreign-pupil teaching (whether they were ready to work with foreign pupils in their previous undergraduate education, where they find benefits, deficiencies in this training? The research used questionnaire survey techniques for teachers and students and semi-structured interviews for teachers. The partial technique was the analysis of study subjects focused on the education of foreign pupils at the Faculty of Education at West Bohemian University in Pilsen (hereinafter WBU. The research group was made up of teachers of the 1st grade of primary schools of the Pilsen and Karlovy Vary regions and students of the 4th grade of the field of Teaching for the

  20. Pupil size and social vigilance in rhesus macaques

    Directory of Open Access Journals (Sweden)

    R Becket Ebitz

    2014-05-01

    Full Text Available Complex natural environments favor the dynamic alignment of neural processing between goal-relevant stimuli and conflicting but biologically salient stimuli like social competitors or predators. The biological mechanisms that regulate dynamic changes in vigilance have not been fully elucidated. Arousal systems that ready the body to respond adaptively to threat may contribute to dynamic regulation of vigilance. Under conditions of constant luminance, pupil diameter provides a peripheral index of arousal state. Although pupil size varies with the processing of goal-relevant stimuli, it remains unclear whether pupil size also predicts attention to biologically salient objects and events like social competitors, whose presence interferes with current goals. Here we show that pupil size in rhesus macaques both reflects the biological salience of task-irrelevant social distractors and predicts vigilance for these stimuli. We measured pupil size in monkeys performing a visual orienting task in which distractors—monkey faces and phase-scrambled versions of the same images—could appear in a congruent, incongruent, or neutral position relative to a rewarded target. Baseline pupil size under constant illumination predicted distractor interference, consistent with the hypothesis that pupil-linked arousal mechanisms regulate task engagement and distractibility. Notably, pupil size also predicted enhanced vigilance for social distractors, suggesting that pupil-linked arousal may adjust the balance of processing resources between goal-relevant and biologically important stimuli. The magnitude of pupil constriction in response to distractors closely tracked distractor interference, saccade planning and the social relevance of distractors, endorsing the idea that the pupillary light response is modulated by attention. These findings indicate that pupil size indexes dynamic changes in attention evoked by both the social environment and arousal.

  1. The Tectonic Evolution of Caribbean Ophiolites

    Science.gov (United States)

    Draper, G.

    2001-12-01

    Ophiolitic rocks (associated basalts, gabbros and ultramafic rocks) occur in many areas in the circum-Caribbean and Central America. These ophiolites are derived principally from two oceanic provinces: (1) the Atlantic realm, proto-Caribbean sea that formed when North America separated from South America during the opening of the North Atlantic during Jurassic and Early Cretaceous time. These ophiolites were emplaced during a series of late Cretaceous to early Tertiary arc-continent collisions as the east facing Antilles arc migrated into the Caribbean realm. These occurrences include Guatamala, northern Cuba, northern Hispaniola, and northern Venezuela. (2) the Pacific realm, late Cretaceous Caribbean-Colombian plateau that now occupies the central Caribbean, but outcrops on land in Costa Rica, SW Hispaniola, the Netherlands Antilles and western Colombia. Accretion, emplacement and uplift was aided by their buoyancy and took place at various times during the Caribbean plateau's insertion into the middle American continental gap. A third set of occurrences are more uncertain in origin. The central Hispaniola and SE Puerto Rico ophiolites seem to be Jurassic age oceanic plateau rocks that were emplaced in mid-Cretaceous time during an, subduction polarity reversal episode. The emplacement of the metamorphosed ophiolitic rocks of eastern Jamaica may also be associated with this event, but the adjacent, upper Cretaceous, Bath-Dunrobin complex seems to be more related to the Campanian Yucatan-Antillean arc collision. The ultramafic rocks of Tobago are not oceanic, but represent Alaksan-type, assemblages.

  3. Chimpanzees and humans mimic pupil-size of conspecifics.

    Directory of Open Access Journals (Sweden)

    Mariska E Kret

    Full Text Available Group-living typically provides benefits to individual group members but also confers costs. To avoid incredulity and betrayal and allow trust and cooperation, individuals must understand the intentions and emotions of their group members. Humans attend to other's eyes and from gaze and pupil-size cues, infer information about the state of mind of the observed. In humans, pupil-size tends to mimic that of the observed. Here we tested whether pupil-mimicry exists in our closest relative, the chimpanzee (P. troglodytes. We conjectured that if pupil-mimicry has adaptive value, e.g. to promote swift communication of inner states and facilitate shared understanding and coordination, pupil-mimicry should emerge within but not across species. Pupillometry data was collected from human and chimpanzee subjects while they observed images of the eyes of both species with dilating/constricting pupils. Both species showed enhanced pupil-mimicry with members of their own species, with effects being strongest in humans and chimpanzee mothers. Pupil-mimicry may be deeply-rooted, but probably gained importance from the point in human evolution where the morphology of our eyes became more prominent. Humans' white sclera surrounding the iris, and the fine muscles around their eyes facilitate non-verbal communication via eye signals.

    2015-09-01

    Full Text Available The results of Slovene and foreign studies reveal the connection between literacy levels and the level of education, employment opportunities and consequent socio-economic status of individuals and families. Reading efficiency relating to reading comprehension is an important element of reading literacy performance. The findings of several authors indicate empirical evidence of the existence of deficits and poor reading comprehension in pupils living in poverty and stress the importance of offsetting deficits and developing reading comprehension. Results of both foreign and Slovene studies indicate that the program of reading comprehension should be implemented in this group of pupils. In the article, we want to present effectiveness of the reading comprehension improvement program in pupils living in poverty. According to the findings of our research, in which we structured and implemented the reading comprehension program for pupils living in poverty with the Metacognitive-intersentential model of reading comprehension, the reading comprehension of the experimental group pupils who participated in the program improved compared to the control group pupils who did not participate in the program. Experimental group pupils also significantly improved correctness of their reading, their vocabulary and skills of verbal expression. When the program ended, we tested its efficiency by applied tests. The results on the manifest variables indicated that the program was good and efficient for pupils who live in poverty and experience reading comprehension problems.

    This study was conducted to assess dynamic visual acuity (DVA) under pupil dilation. Pupil dilation may negatively affect driving performance. Thirty healthy young adults (mean age 29.4 years) with pupil dilation participated in this study as the Mydrin P group. In addition to them, 15 healthy young adults (mean age 28.5 years) without pupil dilation were enrolled as the control group. DVA was measured binocularly with free-head viewing at 0, 30, 60, 120, and 360 min after mydriatic drop instillation in both eyes. Pupil size was measured at each time. In the Mydrin P group, DVA significantly improved at 30, 60, and 120 min (ANOVA; p DVA did not significantly change at all measured times (ANOVA; p > .9). DVA was significantly (p DVA was related to the enlargement of the pupil. This study suggests that the pupil size is one factor that may affect DVA. Potential applications of this study include useful information to assess the effect of pupil dilation on driving performance.

    Hill, Deanna D; Cauley, Jane A; Bunker, Clareann H; Baker, Carol E; Patrick, Alan L; Beckles, Gloria L A; Wheeler, Victor W; Zmuda, Joseph M

    2008-07-01

    Population dynamics predict a drastic growth in the number of older minority women, and resultant increases in the number of fractures. Low bone mineral density (BMD) is an important risk factor for fracture. Many studies have identified the lifestyle and health-related factors that correlate with BMD in Whites. Few studies have focused on non-Whites. The objective of the current analyses is to examine the lifestyle, anthropometric and health-related factors that are correlated with BMD in a population based cohort of Caribbean women of West African ancestry. We enrolled 340 postmenopausal women residing on the Caribbean Island of Tobago. Participants completed a questionnaire and had anthropometric measures taken. Hip BMD was measured by DXA. We estimated volumetric BMD by calculating bone mineral apparent density (BMAD). BMD was >10% and >25% higher across all age groups in Tobagonian women compared to US non-Hispanic Black and White women, respectively. In multiple linear regression models, 35-36% of the variability in femoral neck and total hip BMD respectively was predicted. Each 16-kg (one standard deviation (SD)) increase in weight was associated with 5% higher BMD; and weight explained over 10% of the variability of BMD. Each 8-year (1 SD) increase in age was associated with 5% lower BMD. Current use of both thiazide diuretics and oral hypoglycemic medication were associated with 4-5% higher BMD. For femoral neck BMAD, 26% of the variability was explained by a multiple linear regression model. Current statin use was associated with 5% higher BMAD and a history of breast feeding or coronary heart disease was associated with 1-1.5% of higher BMAD. In conclusion, African Caribbean women have the highest BMD on a population level reported to date for women. This may reflect low European admixture. Correlates of BMD among Caribbean women of West African ancestry were similar to those reported for U.S. Black and White women.

    Full Text Available Background: Multiple myeloma (MM is the second most common malignancy in the United States and has a higher incidence in the black and Afro-Caribbean population. There remain limited data on disease presentation and clinical characteristics in this patient group in the United States. The clinical profile of MM in this underrepresented patient group is described here. Methods: This retrospective study was conducted at Kings County Hospital, an urban New York City hospital in a majority Afro-Caribbean neighborhood. Data from patients diagnosed with MM from 2000 through 2013 were collected from the institution’s tumor registry. Clinical and demographic characteristics of these patients were then analyzed. Results: Patients with a diagnosis of MM were identified (N = 287. Data were available for 231 patients and of these, 97% self-identified as black. 55% were female, and there was a male-to-female ratio of 1:1.2. The mean age of female patients was 64 years; that of male patients was 63 years. Of the 231 patients, 81% had anemia, 68% had bone lesions, 47% had renal impairment, and 29% had hypercalcemia. Low levels of monoclonal protein were present in 27% of patients and 57% had disease of International Staging System stages I and II. Women had higher BMI than men. Conclusion: The mean age of presentation of MM in Afro-Caribbean patients is similar to that in the standard population; however, unlike the general US population, there was a higher incidence in women; mean BMI of women also was higher than that of male patients. A sizeable percentage of Afro-Caribbean patients with MM presented with low levels of monoclonal protein in the presence of multiorgan involvement and damage, suggesting the need for early and aggressive diagnostic testing.

    2015-04-01

    We evaluated the association between intimate partner violence and the mental and physical health status of US Caribbean Black and African American women. We used 2001 to 2003 cross-sectional data from the National Survey of American Life-the most detailed study to date of physical and mental health disorders of Americans of African descent. We assessed participants' health conditions by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (Washington, DC; American Psychological Association) Composite International Diagnostic Interview. We found differences in health conditions between abused African American and Caribbean Black women. There were increased risks for lifetime dysthymia, alcohol dependence, drug abuse, and poor perceived health for African American victims of partner abuse, and binge eating disorder was associated with partner violence among Caribbean Black women. Severe intimate partner violence was associated with negative mental and physical health outcomes for US Black women, with different patterns between African American and Caribbean Blacks. Understanding intimate partner violence experiences of US Black women requires recognition of key intragroup differences, including nativity and immigrant status, and their differential relationships to women's health.

    2015-09-01

    The National Institute of Clinical Excellence suggested black ethnic minorities with epilepsy have different cultural, communicative and health-care needs. However, little is known about these despite increasing migration of black African and Caribbean people to Europe. This study aims to explore perceptions and experiences of epilepsy among black African and Caribbean people in South London. Semi-structured interviews were undertaken with 11 participants, to examine their beliefs and perceptions of living with epilepsy. Interviews were recorded, transcribed, codes generated and thematic analysis undertaken. African participants described supernatural causes for epilepsy and experienced considerable stigma whereas Caribbean participants described epilepsy as a 'normal illness'. However, both African and Caribbean participants experienced social restrictions arising from their epilepsy. The findings of higher levels of perceived stigma and social restriction seen in African participants may be a continuation of beliefs reported in participants' country of origin. There is also evidence that views regarding epilepsy transition through generations vary depending on place of birth. Practical Implications Health-care professionals need to be aware of and engage with the particular beliefs and concerns of black African and Caribbean people to achieve equity in health outcomes.

  13. Medical tourism in the Caribbean.

    Science.gov (United States)

    Ramírez de Arellano, Annette B

    2011-01-01

    Although travel for medical reasons has a long history, it has more recently evolved from a cottage industry to a worldwide enterprise. A number of countries are positioning themselves to attract visitors who are willing to travel to obtain health services that are more accessible, less expensive, or more available than in their countries of origin. This has in turn given rise to medical packages that combine tourism with health. Several Caribbean nations - including Cuba, Barbados, Jamaica, and Puerto Rico - hope to expand their revenues in this new market. Each country has selected specific service niches and promotes its services accordingly. While Cuba has been promoting its services to other countries for several decades, medical tourism is just beginning in the other islands. Ultimately, these nations' economic success will hinge on their comparative advantage vis-à-vis other options, while their success in terms of improving their own health care depends on the extent to which the services for tourists are also available to the islands' populations.

  14. Engaging Parents and Pupils in Astronomy

    2016-04-01

    "The British National Space Centre partnership has recognised for some time that Space and Astronomy are particularly attractive subjects for school students and that including these in the science curriculum can have a positive effect on student interest in science. Drivers are that the number of young people studying science and engineering subjects at A-level and beyond is declining; young people should have an understanding of the importance of science and technology to the world around them; and that UK space industry (including technology, engineering, space science, Earth observation science) must renew itself." BRINGING SPACE INTO SCHOOL Professor Martin Barstow, University of Leicester Published by PPARC on behalf of the British National Space Centre Partnership October 2005 "It has become more and more difficult to persuade young people to follow a career in STEM (Science, Technology, Engineering & Mathematics) subjects. Across the EU, the number of graduates in STEM subjects has dropped from 24.3% in 2002 to 22.6% in 2011" (Source EUSTAT) It was Martin Barstow's report in 2005 that started my attempt to interest people in Science and Technology, At Ormiston Victory Academy (OVA) for the past two years, we have embarked on a program to enthuse pupils to study science related subject through the medium of Astronomy. We teach Edexcel GCSE Astronomy to a joint parent and pupil group. They study together and at the end of the course, both take the GCSE examination. The idea is that the pupils see that science is important to their parents and that a very practical facet of science is also fun. Astronomy is a multidisciplinary course bringing together elements of Science, Maths, Technology, Geography and History. It is hoped that the enthusiasm shown by the pupils will spill over into the mainstream subjects including maths. The parents get an idea of the work and level of knowledge required by their children to complete a GCSE level subject. They also report

    Young male and female workers are over-represented in statistics concerning negative outcomes of poor work environment and risky work. Young workers often have low awareness of risk, a lack of safety training, and inadequate introduction to the work. The aim of this study was to identify the knowledge and experiences of pupils of vocational schools concerning potential work environment risks in their future work. The study design was a dual one, and included a questionnaire and focus group interviews. The study group consisted of 239 pupils from 10 upper secondary schools, who were graduating pupils in four vocational programs: the Industrial Technology Programme, the Restaurant Management and Food Programme, the Transport Programme, and the Handicraft Programme (in which students specialize in wood products). The upper secondary schools were located in the central region of Sweden. The pupils had limited knowledge that employers must, by law, conduct risk analyses and prevent risks. Many felt that they themselves are mainly responsible for performing their tasks safely. Pupils in all programs mentioned acute risk as the greatest risk at work. The theoretical education about safety at work was provided in the 1(st) year of the 3-year vocational programs. A systematic approach to pupils' training in work environment, which is a basis for a safe and healthy workplace, is lacking. The study findings indicate that pupils are offered knowledge far from that intended by laws and by state-of-the-art occupational health risk research.

    Pupil dilations of the eye are known to correspond to central cognitive processes. However, the relationship between pupil size and individual differences in cognitive ability is not as well studied. A peculiar finding that has cropped up in this research is that those high on cognitive ability have a larger pupil size, even during a passive baseline condition. Yet these findings were incidental and lacked a clear explanation. Therefore, in the present series of studies we systematically investigated whether pupil size during a passive baseline is associated with individual differences in working memory capacity and fluid intelligence. Across three studies we consistently found that baseline pupil size is, in fact, related to cognitive ability. We showed that this relationship could not be explained by differences in mental effort, and that the effect of working memory capacity and fluid intelligence on pupil size persisted even after 23 sessions and taking into account the effect of novelty or familiarity with the environment. We also accounted for potential confounding variables such as; age, ethnicity, and drug substances. Lastly, we found that it is fluid intelligence, more so than working memory capacity, which is related to baseline pupil size. In order to provide an explanation and suggestions for future research, we also consider our findings in the context of the underlying neural mechanisms involved. Copyright © 2016 Elsevier Inc.

    To test the hypothesis that marginal ray deviations determine perceived starburst sizes, and to explore different strategies for decreasing starburst size in highly aberrated eyes. Perceived size of starburst images and visual acuities were measured psychophysically for eyes with varying levels of spherical aberration, pupil sizes, and defocus. Computationally, we use a polychromatic eye model including the typical levels of higher order aberrations (HOAs) for keratoconic and post-LASIK eyes to quantify the image quality (the visually weighted Strehl ratio derived from the optical transfer function, VSOTF) with different pupil sizes at both photopic and mesopic light levels. For distance corrected post-LASIK and keratoconic eyes with a night-time pupil (e.g., 7 mm), the starburst diameter is about 1.5 degrees (1 degree for normal presbyopic eyes), which can be reduced to ≤0.25 degrees with pupil sizes ≤3 mm. Starburst size is predicted from the magnitude of the longitudinal spherical aberration. Refracting the eye to focus the pupil margin also removed starbursts, but, unlike small pupils, significantly degraded visual acuity. Reducing pupil diameter to 3 mm improved image quality for these highly aberrated eyes by about 2.7 ×  to 1.7 ×  relative to the natural pupils when light levels were varied from 0.1 to 1000 cd m -2 , respectively. Subjects with highly aberrated eyes observed larger starbursts around bright lights at night predictable by the deviated marginal rays. These were effectively attenuated by reducing pupil diameters to ≤3 mm, which did not cause a drop in visual acuity or modelled image quality even at mesopic light levels. © 2017 The Authors Ophthalmic & Physiological Optics © 2017 The College of Optometrists.

    1998-01-01

    This theoretical study of feminism in the Caribbean opens by presenting the contemporary image of the Caribbean and then pointing to the continuing influence of the colonial past in the creation of contemporary community and the establishment of identity. The paper continues with a focus on three aspects of identity, or difference, that have influenced the daily articulation of feminism and academic debates. The first concerns the positions taken by women in the region's political struggles. The second is an exploration of the linguistic meanings of the gender discourse within the region. Finally, the essay examines the idea of linguistic difference in light of contemporary Western feminist views of "sexual difference" versus equality. The discussion of each of these issues is grounded in historical analysis and illustrated with specific examples. The study concludes that, in this region, feminism offers a new way to investigate the past while creating challenges and opportunities in the struggle to establish a Caribbean identity.

    1981-06-01

    Extension of space--time optics to objects whose transparency is a function of the temporal frequency v = c/lambda is examined. Considering the effects of such stationary pupils on white light waves, they are called temporal pupils. It is shown that simultaneous encoding both in the space and time frequency domains is required to record pupil parameters. The space-time impulse response and transfer functions are calculated for a dispersive nonabsorbent material. An experimental method providing holographic recording of the dispersion curve of any transparent material is presented.

Amherst: University of Massachusetts Press, 1992. x + 185 pp. (Cloth US$ 25.00 Caribbean literature has been overtaken of late by the quarrels that have pitted postmodernists against modernists in Europe and North America for the past twenty years. The modernists, faced with the fragmentation of the region that hard-nosed pragmatists and empiricists could only see as hostile to the emergence of any common culture, had sought in myth and its literary derivatives the collective impulse to transcend the divisions wrought by colonial history. Fifteen years ago I wrote a book that combined in its lead title the terms Modernism and Negritude in an effort to account for the efforts by mid-century Caribbean writers to come to grips with this problem. A decade later I demonstrated that one of the principal Caribbean modernists, Aimé Césaire, late in his career adopted stylistic characteristics that we associate with the postmodern (Arnold 1990. The example of Césaire should not be taken to suggest that we are dealing with some sort of natural evolution of modernism toward the postmodern. In fact the two terms represent competing paradigms that organize concepts and data so differently as to offer quite divergent maps of the literary Caribbean.

    Studies indicate an ethnic density effect, whereby an increase in the proportion of racial/ethnic minority people in an area is associated with reduced morbidity among its residents, though evidence is varied. Discrepancies may arise due to differences in the reasons for and periods of migration, and socioeconomic profiles of the racial/ethnic groups and the places where they live. It is important to increase our understanding of how these factors might promote or mitigate ethnic density effects. Cross-national comparative analyses might help in this respect, as they provide greater heterogeneity in historical and contemporary characteristics in the populations of interest, and it is when we consider this heterogeneity in the contexts of peoples’ lives that we can more fully understand how social conditions and neighbourhood environments influence the health of migrant and racial/ethnic minority populations. This study analysed two cross-sectional nationally representative surveys, in the US and in England, to explore and contrast the association between two ethnic density measures (black and Caribbean ethnic density) and health and experienced racism among Caribbean people. Results of multilevel logistic regressions show that nominally similar measures of ethnic density perform differently across health outcomes and measures of experienced racism in the two countries. In the US, increased Caribbean ethnic density was associated with improved health and decreased experienced racism, but the opposite was observed in England. On the other hand, increased black ethnic density was associated with improved health and decreased experienced racism of Caribbean English (results not statistically significant), but not of Caribbean Americans. By comparing mutually adjusted Caribbean and black ethnic density effects in the US and England, this study examined the social construction of race and ethnicity as it depends on the racialised and stigmatised meaning attributed to

    Studies on argument have found that participants tend to prefer explanations to evidence. This apparent bias toward explanation has been qualified recently by research that has found it to diminish with the availability of evidence. This study examines the use of explanation versus evidence in the context of argumentation with reference to the goals of particular argument situations. Seventy-nine eighth-grade pupils at a regular, urban middle school. The pupils read argumentation scenarios, each having the stated goal of either explaining or proving a claim. The pupils rated the degree to which each of two provided assertions (one a theoretical explanation, and the other evidence-based) helped achieve the goal of the argument. On a second task, the pupils chose which of the two assertions should be more effective in achieving the argument goal. On the third task, the pupils generated either an explanation or evidence for each of the argumentation scenarios. Pupils demonstrated sensitivity to the relative epistemic strength of explanation and evidence. They rated explanations as more advantageous in achieving the explanation goal, and evidence as more advantageous in achieving the proof goal. Conversely, however, when asked to generate or recall an explanation or evidence, pupils produced more explanations than evidence independent of the argumentation goal. The study refines the definition of argumentation context to include specific goals. Pupils were sensitive to the context of the argumentation situation (e.g.goals, availability of evidence). However, they appeared to have a disposition toward explanation when asked to produce an explanation or evidence-based justification.

    A telephone-based survey regarding breast cancer screening practices among 300 African American and Caribbean women age 40 and over in New York City revealed that while U.S.-born women had significantly different sociodemographic profiles (in terms of insurance status, marital status, educational attainment), they were no more likely to have had a mammogram than the foreign-born women. Adjusting for insurance status and source of care, women with a provider recommendation were 8 times more likely ever to have had a mammogram (AOR 8.01, 95%CI: 3.74-17.14). Among foreign-born Caribbean women in the U.S. for less than half their lives, only 52% ever had a provider recommend a mammogram, compared with 77% of U.S.-born women. The findings confirm previous reports of the importance of physician recommendation in increasing mammography screening among urban Black women, and suggest that efforts to reach Caribbean-born women with breast cancer screening messages should emphasize the important role of providers.

    2017-03-01

    Full Text Available The research analyses characteristics of pragmatic abilities of storytelling of pupils with mild intellectual disabilities (MID, in the light of vocabulary characteristics, grammar structure and substantive structure of a story, considering their age and gender. The sample consists of 60 pupils with MID, aged 7 to 9, who attend special school. Child’s pragmatic abilities are assessed with The Storytelling Test. The research results reveal considerable progress of the older group in vocabulary, whereas the progress in grammatical and substantive structure was less substantial. When comparing achievements of pupils with MID according to the vocabulary, grammatical and substantive story structure, no gender differences are determined. A comparison of pragmatic abilities of younger and older groups of pupils with MID with the norms for peers with typical development shows minor deviation of the younger group. The research results reveal characteristics of pragmatic abilities of pupils with MID and can provide insights to speech therapists, teachers, special education teachers and counsellors when considering profiles of individuals that are taken as a basis for designing intervention programs. By implementing such program, we would encourage development of pragmatic abilities of pupils, thus affecting their academic achievements, communication competency and social skills.

    Evidence indicates that teachers can judge pupils on the basis of their physical appearance, including their body shape. Teacher bias towards obese pupils has been suggested as a potential pathway through which obese children attain relatively lower academic levels. The aim of this study was to investigate whether teachers' judgements of pupils' ability are influenced by the body shape of the child. The sample includes English, singleton children in state schools from the Millennium Cohort Study. The data were taken from the fourth wave of data collection, when the children were approximately 7 years old. In all, 5086/5072 children had teacher ability ratings of reading and maths. Logistic regression analyses were used to test whether teachers' perceptions of the child's reading and mathematics ability were influenced by the pupil's waist circumference, conditional upon cognitive test scores of reading and maths ability. After adjustment for cognitive test scores, no significant overall relationship was found between the pupil's waist circumference and the teacher's judgements of ability. No statistically significant differences were observed in the probability of being judged as above average after further adjustments were made for potential confounders. There is little evidence that teachers' judgements of pupils' ability are influenced by obesity.

  14. Social Determinants of Perceived Discrimination among Black Youth: Intersection of Ethnicity and Gender.

    Assari, Shervin; Caldwell, Cleopatra Howard

    2018-02-15

    Most of the existing sociological and epidemiological literature has focused on the protective effects of high socioeconomic status (SES) on population health through reducing exposure to risk factors and increasing human and material resources that can mitigate adversities. Recent studies, however, have documented poor mental health of high SES Blacks, particularly African American males and Caribbean Black females. The literature also shows a link between perceived discrimination and poor mental health. To better understand the extra costs of upward social mobility for minority populations, this study explored ethnic by gender variations in the associations between SES indicators and perceived discrimination in an ethnically diverse national sample of Black youth. This study included 810 African American and 360 Caribbean Black youth who were sampled in the National Survey of American Life-Adolescent supplement (NSAL-A). Three SES indicators (financial hardship, family income, and income to needs ratio) were the independent variables. The dependent variable was perceived (daily) discrimination. Age was the covariate. Ethnicity and gender were the focal moderators. Linear regressions were used for data analysis in the pooled sample and also based on the intersection of ethnicity and gender. Considerable gender by ethnicity variations were found in the patterns of the associations between SES indicators and perceived discrimination.

    Full Text Available Most of the existing sociological and epidemiological literature has focused on the protective effects of high socioeconomic status (SES on population health through reducing exposure to risk factors and increasing human and material resources that can mitigate adversities. Recent studies, however, have documented poor mental health of high SES Blacks, particularly African American males and Caribbean Black females. The literature also shows a link between perceived discrimination and poor mental health. To better understand the extra costs of upward social mobility for minority populations, this study explored ethnic by gender variations in the associations between SES indicators and perceived discrimination in an ethnically diverse national sample of Black youth. This study included 810 African American and 360 Caribbean Black youth who were sampled in the National Survey of American Life—Adolescent supplement (NSAL-A. Three SES indicators (financial hardship, family income, and income to needs ratio were the independent variables. The dependent variable was perceived (daily discrimination. Age was the covariate. Ethnicity and gender were the focal moderators. Linear regressions were used for data analysis in the pooled sample and also based on the intersection of ethnicity and gender. Considerable gender by ethnicity variations were found in the patterns of the associations between SES indicators and perceived discrimination. Financial hardship was a risk factor for perceived discrimination in African American males only. High family income and income to needs ratio were associated with high (but not low perceived discrimination in African American males and Caribbean Black females.

    Full Text Available The main aim of this article is to answer the following research question: How can we prepare student teachers to deal with pupils who have a wide range of day-to-day experiences of the digital world? This question arises out of the understanding that today's student-teacher training is inadequately equipped to realize the potential for learning found in the way that digital technology is now an integral part of the social and cultural practices of children and young people. Based on theory and practice from research and development activities in primary and lower secondary school, the article points out some perspectives connected to the technology culture of children and young people that may have importance for the professional training of student teachers. The article concludes by summarizing some findings from a research project in general teacher education, where it is argued that student teachers can be qualified to cope with the way children and young people use technology by teaching them to adopt solutions based on personal publishing. In many ways the article deals with classical issues in the education field; how the relations between cognition, learning, technology and fellow-citizenship raise practical issues connected to teaching and learning (Dewey, 1915; 1938; 1958.

  17. Born Pupils? Natural Pedagogy and Cultural Pedagogy.

    The theory of natural pedagogy is an important focus of research on the evolution and development of cultural learning. It proposes that we are born pupils; that human children genetically inherit a package of psychological adaptations that make them receptive to teaching. In this article, I first examine the components of the package-eye contact, contingencies, infant-directed speech, gaze cuing, and rational imitation-asking in each case whether current evidence indicates that the component is a reliable feature of infant behavior and a genetic adaptation for teaching. I then discuss three fundamental insights embodied in the theory: Imitation is not enough for cumulative cultural inheritance, the extra comes from blind trust, and tweaking is a powerful source of cognitive change. Combining the results of the empirical review with these insights, I argue that human receptivity to teaching is founded on nonspecific genetic adaptations for social bonding and social learning and acquires its species- and functionally specific features through the operation of domain-general processes of learning in sociocultural contexts. We engage, not in natural pedagogy, but in cultural pedagogy. © The Author(s) 2016.

    Full Text Available Abstract Background Population health status scores are routinely used to inform economic evaluation and evaluate the impact of disease and/or treatment on health. It is unclear whether the health status in black and minority ethnic groups are comparable to these population health status data. The aim of this study was to evaluate health-status in South Asian and African-Caribbean populations. Methods Cross-sectional study recruiting participants aged ≥ 45 years (September 2006 to July 2009 from 20 primary care centres in Birmingham, United Kingdom.10,902 eligible subjects were invited, 5,408 participated (49.6%. 5,354 participants had complete data (49.1% (3442 South Asian and 1912 African-Caribbean. Health status was assessed by interview using the EuroQoL EQ-5D. Results The mean EQ-5D score in South Asian participants was 0.91 (standard deviation (SD 0.18, median score 1 (interquartile range (IQR 0.848 to 1 and in African-Caribbean participants the mean score was 0.92 (SD 0.18, median 1 (IQR 1 to 1. Compared with normative data from the UK general population, substantially fewer African-Caribbean and South Asian participants reported problems with mobility, usual activities, pain and anxiety when stratified by age resulting in higher average health status estimates than those from the UK population. Multivariable modelling showed that decreased health-related quality of life (HRQL was associated with increased age, female gender and increased body mass index. A medical history of depression, stroke/transient ischemic attack, heart failure and arthritis were associated with substantial reductions in HRQL. Conclusions The reported HRQL of these minority ethnic groups was substantially higher than anticipated compared to UK normative data. Participants with chronic disease experienced significant reductions in HRQL and should be a target for health intervention.

    Full Text Available One of the most important roles of spare time physical education is the formation of a positive attitude towards sports activities and sports among pupils. The formation of a positive attitude can play an important role in the matter of a child's healthy lifestyle. Therefore the authors of this article decided to find out what kind of a relationship and an attitude the pupils of primary schools take towards physical education and sports activities in the Detva and Zvolen regions. The authors of this article present the attitudes towards physical education and movement as well as sports activities of 8th grade primary school pupils in the Detva and Zvolen regions as well as to their frequency. The authors discuss which activities among extracurricular or spare-time activities are the most interesting for pupils. According to the results presented in the charts, it is clear that pupils take a positive attitude towards physical education and sports activities. Sports games belong among the most favourite interest groups.

    Eye tracker is an important instrument for research in psychology, widely used in attention, visual perception, reading and other fields of research. Because of its potential function in human-computer interaction, the eye gaze tracking has already been a topic of research in many fields over the last decades. Nowadays, with the development of technology, non-intrusive methods are more and more welcomed. In this paper, we will present a method based on the shape of pupil image to estimate the gaze point of human eyes without any other intrusive devices such as a hat, a pair of glasses and so on. After using the ellipse fitting algorithm to deal with the pupil image we get, we can determine the direction of the fixation by the shape of the pupil.The innovative aspect of this method is to utilize the new idea of the shape of the pupil so that we can avoid much complicated algorithm. The performance proposed is very helpful for the study of eye gaze tracking, which just needs one camera without infrared light to know the changes in the shape of the pupil to determine the direction of the eye gazing, no additional condition is required.

    After cataract surgery, the ability to accommodate is lost. For this reason, a mechatronic IOL is being developed at the moment: The Artificial Accommodation System. This device requires an easily measureable indicator of the distance of the observed object to determine the demand of accommodation. As the pupil constricts with near vision, pupil size might be such an indicator. Our research focused on whether the pupil can control an artificial lens. A study with 14 healthy subjects aged between 24 and 64 years was conducted. An artificial lens with variable refractive power was mounted in front of one eye. In this eye, natural accommodation was greatly reduced or absent due to presbyopia, pseudophakia, or iatrogenic cycloplegia. The lens' refractive power was changed in a computer-controlled manner depending on changes in the pupil diameter of the second eye, which could not see the fixation stimulus. The subject's task was to get a clear focused image of the target in different distances. The lens can be controlled by the pupil intuitively (P < 1.8 × 10(-18)). Without prior knowledge, 11/14 subjects passed the first trial, and 31/41 trials were successful. Only one subject was not able to control the lens at all. Most subjects comprehended instantly how to use the unfamiliar lens control to bring a target into focus. This study emphasizes the plasticity of the visual control system. Positioning accuracy was acceptable, but the control must be optimized to facilitate maintaining a defined refractive power.

    PurposeIt is purported that caffeine, an autonomic stimulant, affects visual performance. This study sought to assess whether caffeine intake was associated with changes in pupil size and/or amplitude of accommodation.Patients and methodsA double-masked, crossover study was conducted in 50 healthy subjects of age range 19 to 25 years. Subjects were randomized to treatments such that subjects consumed either 250 mg caffeine drink or vehicle on separate days. Amplitude of accommodation was measured by the push-up technique, and pupil size using a millimeter ruler fixed to a slit lamp biomicroscope in dim illumination (5 lux). Amplitude of accommodation and pupil size were taken at baseline, and at 30, 60 and 90 min time points post treatment. Repeated measures one-way ANOVA and paired t-test were used in analyzing data.ResultsAmplitude of accommodation and pupil size after caffeine intake were significantly greater than vehicle (Pcaffeine beverage was associated with significant increases in amplitude of accommodation and pupil size with time (Pcaffeine. This study suggests caffeine may have some influence on visual functions.

    2015-09-01

    Recent studies have suggested that pupil diameter, like the "old-new" ERP, may be a measure of memory. Because the amplitude of the old-new ERP is enhanced for items encoded in the context of repetitions that are distributed (spaced), compared to massed (contiguous), we investigated whether pupil diameter is similarly sensitive to repetition. Emotional and neutral pictures of natural scenes were viewed once or repeated with massed (contiguous) or distributed (spaced) repetition during incidental free viewing and then tested on an explicit recognition test. Although an old-new difference in pupil diameter was found during successful recognition, pupil diameter was not enhanced for distributed, compared to massed, repetitions during either recognition or initial free viewing. Moreover, whereas a significant old-new difference was found for erotic scenes that had been seen only once during encoding, this difference was absent when erotic scenes were repeated. Taken together, the data suggest that pupil diameter is not a straightforward index of prior occurrence for natural scenes. © 2015 Society for Psychophysiological Research.

    Studies of causal attributions for difficult pupil behaviour in schools have tended to focus on the perspectives of teachers. The present study examines the causal attributions made by parents for difficult behaviour in classrooms. It reveals the structure of these attributions and serves as a direct comparison to a previous study of pupils' attributions (Miller, Ferguson, & Byrne, 2000) and, more indirectly, with the teacher studies. The participants were 144 parents (106 mothers and 38 fathers) whose children all attended the same inner city school. A questionnaire was constructed following three initial small group interviews with parents to identify the wide range of factors they viewed as potential causes of difficult classroom behaviour. This was then administered to all the parents of children attending the same inner-city primary school. Factor analysis indicated that parents' attributions for misbehaviour were best represented by three factors: (1) 'fairness of teachers' actions', (2) 'pupil vulnerability to peer influences and adverse family circumstances', and (3) 'differentiation of classroom demands and expectations'. While there were no differences between parents in terms of gender or ethnicity, they did see the first two factors as more significant contributors to pupil misbehaviour than the third. There is both agreement and conflict between parents' attributions and those made by pupils and by teachers. The implementation of policy initiatives, such as home-school agreements and Pastoral Support Programmes, risk exacerbating tensions and difficulties if these differences in attributions are not acknowledged and acted upon.

    Recent changes in the strategy of the Caribbean Contraceptive Social Marketing Project emphasize the condom, under the brand name, Panther. Since 1984, CCSMP began marketing their Perle rand of oral contraceptive, since dropped, in Barbados, St. Vincent and St. Lucia. Now wider commercial connections are envisioned, with support by CCSMP to promote generic brands. The Panther condom campaign will include an array of mass media, point-of-purchase and sporting event advertising. Pharmacies report that Panther is selling as well as the leading commercial brand. CCSMP is looking to introduce an ultra-thin condom and a vaginal foaming tablet. Market research, involving physicians and users as well as retail audits, indicates that although population in numbers alone is not a serious problem in the Caribbean, early pregnancy is a concern in the area.

    Although the link between depression and lower levels of mastery is well established, limited information exists on ethnic and gender differences in the association between the two. The current study investigated ethnic, gender, and ethnic by gender differences in the link between major depressive disorder (MDD) and low mastery in the United States. We used data from the National Survey of American Life-Adolescent supplement (NSAL-A), 2003-2004. In total, 1170 Black adolescents entered the study. This number was composed of 810 African-American and 360 Caribbean Black youth (age 13 to 17). Demographic factors, socioeconomic status (family income), mastery (sense of control over life), and MDD (Composite International Diagnostic Interview, CIDI) were measured. Logistic regressions were used to test the association between mastery and MDD in the pooled sample, as well as based on ethnicity and gender. In the pooled sample, a higher sense of mastery was associated with a lower risk of MDD. This association, however, was significant for African Americans but not Caribbean Blacks. Similarly, among African American males and females, higher mastery was associated with lower risk of MDD. Such association could not be found for Caribbean Black males or females. Findings indicate ethnic rather than gender differences in the association between depression and mastery among Black youth. Further research is needed to understand how cultural values and life experiences may alter the link between depression and mastery among ethnically diverse Black youth.

    This paper addresses the dilemma facing the Caribbean in the establishment of policies that would lead to HIV prevention. The Caribbean are a collection of numerous cultures, languages, politics, and economies. It has a high number of AIDS cases relative to it's population size. At the onset of the AIDS epidemic, a series of bad studies led to the conclusion that Haitians were a "risk group" for HIV infection, consequences of which are irreparable. The AIDS epidemic has been characterized by attitudes of fear, and resentment of HIV infected persons. For instance, AIDS victims are totally excluded from controversial AIDS related discussions. Whereas in Trinidad and Tobago, widespread promotion of condoms is ongoing to control the spread of HIV infection. Cuba on the other hand, has tested most of it's population for HIV infection, and those who are infected have been isolated into medically equipped buildings. This approach, though effective, cannot be sustained by any other island in the Caribbean. In fact, issues of routine hospital blood screening tend to be problematic given the very low seroprevalence rates relative to the resources needed for testing. In all islands however, there is a drive to keep the blood supply free of HIV infection, and health workers well educated on AIDS related facts. However, education is not enough; there needs to be a change in feelings and attitudes that facilitate high risk behavior.

    Sykes et al. have demonstrated that the Caribbean plate has moved east-northeast about 1400 km since late Eocene time (38 Ma). This movement changes or affects the interpretation of many biogeographic problems of that region. For example, Woodring's 1965 “Middle Miocene Caribbean Province,” although slightly larger peripherally, includes the same area as the Caribbean plate; the migration route by which the North American terrestrial mammals reached the Panamanian area in the early Miocene may have been via the Nicaraguan Rise rather than through present-day Guatemala; Petuch's “relict Neogene gastropod fauna” from northern Colombia and Venezuela may have been carried along with the plate as it moved; the otherwise Pacific keyhole echinoid genus Mellitella's anomalous fossil occurrences in Venezuela and Colombia are explained by the plate movement.

    Humankind is strongly affected by natural hazards: Earthquakes and volcanoes shake the solid earth, storms and floods happen more and more frequently due to climate change, tsunamis threaten coastal areas. As the human population continues to expand, and stresses on the environment multiply, the need for an understanding of the fundamental issues becomes more urgent. A major task of Collaborative Research Centre "Climate - Biogeochemistry Interactions in the Tropical Ocean" and Collaborative Research Centre "Volatiles and Fluids in Subduction Zones" is to explain how the different components of the earth system interact and how they affect the world's population. Both Collaborative Research Centres implement a joint outreach program to communicate their research activities and results to the general public. In doing so, new strategies in public outreach are essential - considering the fast pace of changes in communication media and the increasing importance of edutainment as a way to reach the public and particularly the younger generations. Outreach materials have to be interesting, easy to understand and fun to explore, but without sacrificing the scientific content. Therefore, videos for the internet (e. g. Youtube) are one promising way to reach that target group. Blogs, podcasts, wikis or being part of social networks such as Facebook are further ways. But "being present where young people are" is not enough. You have to speak their language, too. To take another step forward we hence involve a critical part of the target audience actively into this new communication strategy. School students are able to contribute innovative views and their own language in presenting science to the public. In cooperation with pupils and teachers, we experiment with those new approaches to public outreach. Wherever it is possible, we are also making use of international cooperations of both Collaborative Research Centres with partner institutions in Latin America and Western

    Full Text Available In this article Professor Thembela, Vice-Chairman of the Board of Trustees, UPTTRAIL Trust*, sketches some of the issues which constitute major problems in the education of black South Africans. In the first place the discontinuity between the pupils' traditional home background and a Westernized system of education creates severe obstacles. They are aggravated by the fact that black culture is itself in transition. by the contempt with which black culture was regarded by the colonialists and by the discriminatory political practices which denied black education adequate provision. Other issues that further complicate black education are: * the second language medium of instruction which has been adopted for the purpose of securing international participation but which doubles the burden on the black learner and contributes to an appalling failure rate * the inadequate qualifications of black teachers * inadequate financing of black education * the impoverished communities from which black pupils and teachers come * the perception among many black pupils that their education is inferior * the situation of cultural, social and political conflict created by the development of black education. To remedy such a situation, intervention of an exceptional nature is needed. The UPTTRAIL project promises to provide such intervention. In hierdie artikel skets Professor Thembela, Vise-voorsitter van die Raad van Trustees, UPTTRAIL Trust, van die hoofprobleme in die swart onderwys in Suid-Afrika.

  15. Pupil-mimicry conditions trust in partners: moderation by oxytocin and group membership.

    Kret, Mariska E; De Dreu, Carsten K W

    2017-03-15

    Across species, oxytocin, an evolutionarily ancient neuropeptide, facilitates social communication by attuning individuals to conspecifics' social signals, fostering trust and bonding. The eyes have an important signalling function; and humans use their salient and communicative eyes to intentionally and unintentionally send social signals to others, by contracting the muscles around their eyes and pupils. In our earlier research, we observed that interaction partners with dilating pupils are trusted more than partners with constricting pupils. But over and beyond this effect, we found that the pupil sizes of partners synchronize and that when pupils synchronously dilate, trust is further boosted. Critically, this linkage between mimicry and trust was bound to interactions between ingroup members. The current study investigates whether these findings are modulated by oxytocin and sex of participant and partner. Using incentivized trust games with partners from ingroup and outgroup whose pupils dilated, remained static or constricted, this study replicates our earlier findings. It further reveals that (i) male participants withhold trust from partners with constricting pupils and extend trust to partners with dilating pupils, especially when given oxytocin rather than placebo; (ii) female participants trust partners with dilating pupils most, but this effect is blunted under oxytocin; (iii) under oxytocin rather than placebo, pupil dilation mimicry is weaker and pupil constriction mimicry stronger; and (iv) the link between pupil constriction mimicry and distrust observed under placebo disappears under oxytocin. We suggest that pupil-contingent trust is parochial and evolved in social species in and because of group life. © 2017 The Authors.

    1985-01-01

    Anatomical, experimental, and computer simulation studies were used to determine the structure of the neurophysiological model of the pupil size control system. The computer simulation of this model demonstrates the role played by each of the elements in the neurological pathways influencing the size of the pupil. Simulations of the effect of drugs and common abnormalities in the system help to illustrate the workings of the pathways and processes involved. The simulation program allows the user to select pupil condition (normal or an abnormality), specific site along the neurological pathway (retina, hypothalamus, etc.) drug class input (barbiturate, narcotic, etc.), stimulus/response mode, display mode, stimulus type and input waveform, stimulus or background intensity and frequency, the input and output conditions, and the response at the neuroanatomical site. The model can be used as a teaching aid or as a tool for testing hypotheses regarding the system.

    This paper reports the validation process for research questions that measure cultural identity in a survey of adolescents from a multi-ethnic urban area. Four questions that tapped preferred cultural origins of friends and clothing were used to classify subjects into categories for cultural identity described by Berry (1980). We assessed face, content and construct validity of these questions by: i) investigating the meaning of cultural identity from an African-Caribbean, Bangladeshi, and White British perspective in three focus groups; ii) asking participants to comment on the questions and their suitability for studies of cultural identity; and iii) using data from the Research with East London Adolescents: Community Health Survey (RELACHS) study of adolescents to test hypotheses about associations of acculturation with health outcomes (physical and mental) in order to assess whether these trends are consistent with previous research, and are in accord with trends predicted by the Berry model. Questions about the cultural origins of friends and clothing showed good face and content validity. However, only the questions on friendship choices showed some associations in the predicted directions, with some associations that were unexpected. The most significant findings were that, in comparison with marginalised pupils, for African-Caribbean pupils assimilation was associated with more tiredness (OR=40.7, 3.8-432.8,p<0.001) and traditionalism with less obesity (OR=0.1, 0.02-0.5, p<0.001). For Bangladeshi pupils integration was associated with a lower risk of depression (OR=0.4, 0.2-0.8, p<0.001). Questions on friendship choices can be used to assess cultural identity, but associations with health and health risk behaviours are different for each ethnic group.

  18. CARICOF - The Caribbean Regional Climate Outlook Forum

    2013-04-01

    Regional Climate Outlook Forums (RCOFs) are viewed as a critical building block in the Global Framework for Climate Services (GFCS) of the World Meteorological Organization (WMO). The GFCS seeks to extend RCOFs to all vulnerable regions of the world such as the Caribbean, of which the entire population is exposed to water- and heat-related natural hazards. An RCOF is initially intended to identify gaps in information and technical capability; facilitate research cooperation and data exchange within and between regions, and improve coordination within the climate forecasting community. A focus is given on variations in climate conditions on a seasonal timescale. In this view, the relevance of a Caribbean RCOF (CARICOF) is the following: while the seasonality of the climate in the Caribbean has been well documented, major gaps in knowledge exist in terms of the drivers in the shifts of amplitude and phase of seasons (as evidenced from the worst region-wide drought period in recent history during 2009-2010). To address those gaps, CARICOF has brought together National Weather Services (NWSs) from 18 territories under the coordination of the Caribbean Institute for Meteorology and Hydrology (CIMH), to produce region-wide, consensus, seasonal climate outlooks since March 2012. These outlooks include tercile rainfall forecasts, sea and air surface temperature forecasts as well as the likely evolution of the drivers of seasonal climate variability in the region, being amongst others the El Niño Southern Oscillation or tropical Atlantic and Caribbean Sea temperatures. Forecasts for both the national-scale forecasts made by the NWSs and CIMH's regional-scale forecast amalgamate output from several forecasting tools. These currently include: (1) statistical models such as Canonical Correlation Analysis run with the Climate Predictability Tool, providing tercile rainfall forecasts at weather station scale; (2) a global outlooks published by the WMO appointed Global Producing

    Assari, Shervin

    2014-04-01

    Most studies on mental health associates of obesity have focused on depression and less is known about the role of anxiety in obesity. This study compared the additive effects of General Anxiety Disorder (GAD) and Major Depressive Disorder (MDD) on Body Mass Index (BMI) across sub-populations of Blacks based on the intersection of ethnicity and gender. Data came from the National Survey of American Life (NSAL), 2001 - 2003. The participants consisted of 3,570 African Americans and 1,621 Caribbean Blacks. Twelve-month MDD and GAD were determined using the World Mental Health Composite International Diagnostic Interview (CIDI). Levels of BMI were categorized based on being equal to or larger than 25, 30, 35, and 40 kg/m(2). We fitted linear regression models specific for our groups, which were defined based on the intersection of ethnicity and gender. Additionally, age, education, marital status, employment, and region were controlled. Among Caribbean Black men and African American women, lifetime GAD, but not MDD, was associated with high BMI. Among Caribbean Black women, lifetime MDD, but not GAD, was associated with high BMI. Intersection of ethnicity and gender may determine how anxiety and depression are associated with BMI among Blacks. Sub-populations of Blacks (e.g. based on ethnicity and gender) may have specific mental health determinants or consequences of obesity. Future research should investigate how and why the additive effects of anxiety and depression on obesity vary across ethnic and gender groups of Blacks.

    2015-03-01

    Spirituality may contribute to the health advantage of foreign-born blacks compared to United States (US)-born blacks. The objective of this study was to test the hypothesis that spirituality attenuates the association of psychosocial stress to stress-associated metabolic risk factors among foreign-born Caribbean blacks living in a US jurisdiction. Data on demographic factors, anthropometric measurements (height, weight and waist), fasting glucose and insulin, lifestyle behaviors (smoking and alcohol use), psychosocial stress and spirituality were collected from a population-based sample of 319 Afro-Caribbean immigrants, ages 20 and older, who were recruited between 1995 and 2000 in the Virgin Islands of the United States (USVI). Glucose and insulin measurements were used to estimate insulin resistance by the homeostasis model assessment (HOMA-IR) method. Participants were classified into three levels of spirituality, "low", "medium" and "high" based on the distribution of spirituality scores. Stepwise regression analyses were used to identify the significant predictors of waist circumference and HOMA-IR within each level of spirituality. The predictors of waist circumference and HOMA-IR varied across the levels of spirituality. Psychosocial stress was an independent predictor of waist and HOMA-IR only among participants with a low level of spirituality. Spirituality appears to attenuate the association of psychosocial stress to waist circumference and insulin resistance among Afro-Caribbean immigrants in the USVI.

  18. True subduction vs. underthrusting of the Caribbean plate beneath Hispaniola, northern Caribbean

    The Eastern Greater Antilles arc (Hispaniola and Puerto Rico) is bounded by a north-verging accretionary prism on its north side and a south-verging thrust belt (Muertos thrust belt) on its south side. This bivergent geometry has been attributed for the last 30 years to opposing subduction of the North American plate and the Caribbean oceanic interior beneath the island arc at the Muertos margin. Recent observations of seafloor and shallow sub-seafloor deformational features at the Muertos compressive margin together with sandbox kinematic and gravity modeling question the hypothesized subduction of the Caribbean plate's interior beneath the eastern Greater Antilles island arc. To further test the subduction hypothesis, we carried out in 2009 a wide-angle seismic transect across the widest part of the Muertos compressive margin at longitude 69°W. A 2-D forward ray-tracing model of the wide-angle transect outlines the broad-scale crustal structure across the Muertos margin. The Caribbean oceanic slab is imaged beneath the Muertos margin to about 50 km north of the deformation front and down to 19 km depth. A change in crustal p-wave velocity at ~60 km from the deformation front is interpreted as the boundary between the compressive deformed belt and the arc crust. The Caribbean oceanic crust is not seen extending farther north or penetrating the upper mantle. Modeling of ship's gravity data, acquired along the seismic profile, corroborates the seismic results. Any subduction model imply the existence of a regional mass deficit generated by the subducted Caribbean slab beneath the island arc and that variations in the geometry of the subduction angle and the depth are not able to compensate it. Earthquake hypocenter distribution in the Muertos Margin shows diffuse seismicity beneath the island arc, being very hard to identify different clusters and to assign them to different subducted slabs. The diffuse seismicity may be related to the transition between subduction

    2008-03-01

    The present study aimed at determining the relationship of anthropometric dimensions of pupils from grades 1 to 8 in primary school with the dimensions of school chairs. Two dimensions of the chairs in daily use were evaluated to ascertain whether the fit is sufficient and the effect on pupils' sitting posture. The work included a sample of 556 pupils from three primary schools in Zagreb, Croatia and two types of furniture. Dimensions of school chairs were compared with three anthropometric variables of the pupils. Descriptive statistics were analysed for all variables. These study results have shown that furniture of appropriate dimensions is not available to a large number of students in Croatia. Currently supplied classroom equipment is provided in only two sizes and does not fit the users. It is recommended that task chairs may be acceptable if they are issued in four heights or individually adjustable chairs be introduced in Croatian schools. Furthermore it is strongly recommended that schools actively promote appropriate active sitting behaviour.

  17. Zernike olivary polynomials for applications with olivary pupils.

    Science.gov (United States)

    Zheng, Yi; Sun, Shanshan; Li, Ying

    2016-04-20

    Orthonormal polynomials have been extensively applied in optical image systems. One important optical pupil, which is widely processed in lateral shearing interferometers (LSI) and subaperture stitch tests (SST), is the overlap region of two circular wavefronts that are displaced from each other. We call it an olivary pupil. In this paper, the normalized process of an olivary pupil in a unit circle is first presented. Then, using a nonrecursive matrix method, Zernike olivary polynomials (ZOPs) are obtained. Previously, Zernike elliptical polynomials (ZEPs) have been considered as an approximation over an olivary pupil. We compare ZOPs with their ZEPs counterparts. Results show that they share the same components but are in different proportions. For some low-order aberrations such as defocus, coma, and spherical, the differences are considerable and may lead to deviations. Using a least-squares method to fit coefficient curves, we present a power-series expansion form for the first 15 ZOPs, which can be used conveniently with less than 0.1% error. The applications of ZOP are demonstrated in wavefront decomposition, LSI interferogram reconstruction, and SST overlap domain evaluation.

    2000-10-01

    The vitality of Caribbean coral reefs has undergone a continual state of decline since the late 1970s, a period of time coincidental with large increases in transatlantic dust transport. It is proposed that the hundreds of millions of tons/year of soil dust that have been crossing the Atlantic during the last 25 years could be a significant contributor to coral reef decline and may be affecting other ecosystems. Benchmark events, such as near synchronous Caribbean-wide mortalities of acroporid corals and the urchin Diadema in 1983, and coral bleaching beginning in 1987, correlate with the years of maximum dust flux into the Caribbean. Besides crustal elements, in particular Fe, Si, and aluminosilicate clays, the dust can serve as a substrate for numerous species of viable spores, especially the soil fungus Aspergillus. Aspergillus sydowii, the cause of an ongoing Caribbean-wide seafan disease, has been cultured from Caribbean air samples and used to inoculate sea fans.

  7. Caribbean plate tectonics from seismic tomography

    Science.gov (United States)

    Ten Brink, U. S.; Villasenor, A.

    2012-12-01

    New seismic tomography in the Caribbean shows close links between the geometry and dynamics of subducting slabs and the geology of the overriding plate. Unlike most oceanic plates, the Caribbean plate lacks identifiable seafloor magnetic anomalies and fracture zones. The plate's history has therefore been inferred primarily from land geology along the plate boundary, which is complicated by large-scale shear deformation, and from finite rotations of surrounding plates.We used more than 14 million arrival times from 300,000 earthquakes to identify P-wave velocity anomalies. We relate the anomalies to the geometry and dynamics of subducting slabs and to patterns of earthquake activity, volcanism, topographic relief, and tectonic deformation. For example, we detect two separate slabs belonging to the North and South American plates, respectively, which appear to be responsible for morphologic and tectonic differences between the arcs of the Northern (from Guadeloupe northward) and Southern (from Dominica southward) Lesser Antilles. Variations in earthquake activity between Haiti and the Dominican Republic can be explained by a change in slab geometry from an underplated slab beneath Haiti to a subducting slab under the Dominican Republic. A shallow tear in the slab may explain the anomalously deep Puerto Rico Trench and the frequent earthquake swarms there. The westward shift in volcanic activity in the Northern Lesser Antilles from the Miocene Limestone Caribbees to the present arc can be attributed to the limit on convective flow imposed by the 3-D geometry of the slab at depth. A thinned South America slab under the southern Lesser Antilles may result from traction imposed on the slab by a wide forearc wedge. Variations in tectonic deformation of northern South America could be related to the location of the Caribbean Large Igneous Province north of the Maracaibo Block.

    The axis of rotation describing relative motion of the Caribbean plate with respect to South America lies in Canada near Hudson's Bay, such that the Caribbean plate moves nearly due east relative to South America [DeMets et al. 2010]. The plate motion is absorbed largely by pure strike slip motion along the El Pilar Fault in northeastern Venezuela, but in northwestern Venezuela and northeastern Colombia, the relative motion is distributed over a wide zone that extends from offshore to the northeasterly trending Mérida Andes, with the resolved component of convergence between the Caribbean and South American plates estimated at ~10 mm/yr. Recent densification of GPS networks through COLOVEN and COCONet including access to private GPS data maintained by Colombia and Venezuela allowed the development of a new GPS velocity field. The velocity field, processed with JPL's GOA 6.2, JPL non-fiducial final orbit and clock products and VMF tropospheric products, includes over 120 continuous and campaign stations. This new velocity field along with enhanced seismic reflection profiles, and earthquake location analysis strongly suggest the existence of an active oblique subduction zone. We have also been able to use broadband data from Venezuela to search slow-slip events as an indicator of an active subduction zone. There are caveats to this hypothesis, however, including the absence of volcanism that is typically concurrent with active subduction zones and a weak historical record of great earthquakes. A single tsunami deposit dated at 1500 years before present has been identified on the southeast Yucatan peninsula. Our simulations indicate its probable origin is within our study area. We present a new GPS-derived velocity field, which has been used to improve a regional block model [based on Mora and LaFemina, 2009-2012] and discuss the earthquake and tsunami hazards implied by this model. Based on the new geodetic constraints and our updated block model, if part of the

    The "High school class for students with special abilities in physics" was founded in Nis, Serbia (www.pmf.ni.ac.yu/f_odeljenje) in 2003. The basic aim of this project has been introducing a broadened curriculum of physics, mathematics, computer science, as well as chemistry and biology. Now, six years after establishing of this specialized class, and 3 years after the previous report, we present analyses of the pupils' skills in solving rather problem oriented test, as PISA test, and compare their results with the results of pupils who study under standard curricula. More precisely results are compared to the progress results of the pupils in a standard Grammar School and the corresponding classes of the Mathematical Gymnasiums in Nis. Analysis of achievement data should clarify what are benefits of introducing in school system track for gifted students. Additionally, item analysis helps in understanding and improvement of learning strategies' efficacy. We make some conclusions and remarks that may be useful for the future work that aims to increase pupils' intrinsic and instrumental motivation for physics and sciences, as well as to increase the efficacy of teaching physics and science.

    Full Text Available Separability filter method is a reliable method for pupil detection. However, so far this method is implemented for detecting pupil of normal eye, while for abnormal eye such as cataract and glaucoma patients; they have different characteristics of pupil such as color, shape and radius size of pupil. In this paper we propose to use separability filter for detecting pupil of abnormal patients with different characteristics. We faced a problem about radius size, shape and color of pupil; therefore we implemented Hough Transform, Blob area and Brightness for identifying input images before applying separability filter. The experiment results show that we can increase performance of pupil detection for abnormal eye to be 95.65%.

  16. Water Security and Services in the Caribbean

    Directory of Open Access Journals (Sweden)

    Adrian Cashman

    2014-05-01

    Full Text Available The efficient management of water resources and services continues to be a concern in many of the small island states of the Caribbean. There are growing concerns over the ability of governments in the region to ensure the good management and provision of water without jeopardizing economic growth and the maintenance of social well-being. This paper provides an overview of the major factors influencing the water security facing the Caribbean Region and how the emerging concerns are being addressed. The key challenges and vulnerabilities may be summarized as lack of data and barriers to making available what information there is. Forward planning has been largely neglected and is symptomatic of a lack of appreciation of the need for having national water policies. In this respect Jamaica’s development of a national master water plan serves as a good example of what is needed. Water service providers have to be efficient, well managed and allowed to do their job. This means that they have to be on a sound financial footing. The challenge is to find the balance between appropriate political and regulatory oversight and the autonomy of water managers and service providers.

  18. Estimation of Tsunami Risk for the Caribbean Coast

    Zahibo, N.

    2004-05-01

    The tsunami problem for the coast of the Caribbean basin is discussed. Briefly the historical data of tsunami in the Caribbean Sea are presented. Numerical simulation of potential tsunamis in the Caribbean Sea is performed in the framework of the nonlinear-shallow theory. The tsunami wave height distribution along the Caribbean Coast is computed. These results are used to estimate the far-field tsunami potential of various coastal locations in the Caribbean Sea. In fact, five zones with tsunami low risk are selected basing on prognostic computations, they are: the bay "Golfo de Batabano" and the coast of province "Ciego de Avila" in Cuba, the Nicaraguan Coast (between Bluefields and Puerto Cabezas), the border between Mexico and Belize, the bay "Golfo de Venezuela" in Venezuela. The analysis of historical data confirms that there was no tsunami in the selected zones. Also, the wave attenuation in the Caribbean Sea is investigated; in fact, wave amplitude decreases in an order if the tsunami source is located on the distance up to 1000 km from the coastal location. Both factors wave attenuation and wave height distribution should be taken into account in the planned warning system for the Caribbean Sea. Specially the problem of tsunami risk for Lesser Antilles including Guadeloupe is discussed.

  19. Late neogene history of the Pacific-Caribbean gateway

    Science.gov (United States)

    Keller, G.; Zenker, C.E.; Stone, S.M.

    1989-01-01

    Planktic foraminiferal provinces of Caribbean DSDP Hole 502A and East Pacific DSDP Hole 503A have been analyzed and compared with benthic and planktic isotope records, carbonate, hiatus events, and sea level changes. Four major events are evident in the closure history of the Pacific-Caribbean gateway, at 6.2, 4.2, 2.4 and 1.8 Ma. The faunal change at 6.2 Ma coincides with the ??13C shift and is primarily caused by upwelling in the western Caribbean. This suggests restricted circulation of intermediate water and deflection northeastward, strengthening the Gulf Stream as reflected in the first major erosion on Blake Plateau. The second faunal change, at 4.2 Ma, coincides with increased surface water salinity evident in ??18O data and indicates increasingly restricted surface water exchange. Divergence of faunal provinces beginning at 2.4 Ma is marked by increasing abundance of high salinity tolerant species (Globigerinoides ruber) in the Caribbean. This suggests that initial closure of the Pacific-Caribbean gateway and cessation of sustained surface current flow between the Pacific and Caribbean occurred as late as 2.4 Ma. Maximum divergence of faunal provinces begins at 1.8 Ma and continues to the present. This implies that at least incipient littoral-neritic leakage occurred across the Pacific-Caribbean gateway between 2.4 and 1.8 Ma, with final closure by 1.8 Ma. ?? 1989.

  20. Migration and development in the Caribbean: relating policies and people.

    Science.gov (United States)

    Pastor, R

    1985-01-01

    Throughout the 20th century, the US has feared that political instability in the Caribbean area could be exploited by adversaries; therefore, the US and the nations of the Caribbean share a compelling interest in the region's development. The dramatic increase in legal and illegal immigration to the US from the Caribbean in the last 2 decades has offered an additional human reason for US interest in the region. This migration has also created a new source of dependence and vulnerability for the region. Curtailment of migration would undoubtedly affect the region, and if the effect were social and political instability, then the US would also share those consequences. The 1984 Conference on Migration and Development in the Caribbean held discussions to 1) enhance the benefits of migration to Caribbean development, 2) identify development strategies, policies, and projects that would reduce pressures that have accelerated the rate of international migration, making it less manageable and more costly, and 3) identify ways to reduce dependence on migration by expanding employment and assisting economies in the region to become more self-reliant. The attitudes of both US and Caribbean participants seemed to reflect a considerable degree of ambivalence on the migration issue. The US views itself as "a nation of immigrants" and yet is troubled by the recent large influx of immigrants, particularly illegal migrants and refugees. While Americans recognize that the "brain" reduces the development capacity of developing countries, the US still needs and benefits from young immigrants trained in the sciences, engineering, and computers. Caribbean participants were also ambivalent about immigration.

    The variability of the Caribbean current is under the influence of the fresh water input from the Orinoco and Amazon rivers. Sea Surface Salinity maps of the eastern Caribbean show the seasonal extension of the riverine fresh water across the Caribbean basin, from August to December (wet season). The plume is divided into two main cores: one flows into the Caribbean Sea mostly through the Grenada Passage where it merges with the Caribbean Current while the other core is formed further north by advection of the river plume by the North Brazil Current rings. Due to the presence of fresh water the Caribbean Sea mesoscale activity is strongly increased during the wet season. Therefore, both coral reef ecosystems and coastal flows are under the scope of the large scale flow seasonality. The impact of the flow mesoscale seasonality on reef organisms is studied through two reef organisms: (1) Reef-building coral: Genetic analyzes show that populations of the Caribbean reef-building coral, Acropora palmata, have experienced little or no recent genetic exchange between the western and eastern Caribbean. Western Puerto Rico is identified as an area of mixing between the two subregions. Using a bio- physical coupled model accounting for larvae life history traits, we verify the plausibility of a present day oceanographic barrier caused by the Caribbean Current seasonal variability in the vicinity of Mona Passage. (2) Grouper: Several grouper species form spawning aggregations at the shelf edge of the US Virgin Islands starting at the end of the wet season in December. Using ADCP current measurements and numerical simulations, unusual large 'dispersion' pulses are shown to be associated with the presence of sub-mesoscale coherent features more likely to be formed during the wet season. Spawning occurring during the dry season (January to April) is mostly tide driven, suggesting a limited dispersal.

    Full Text Available Factors interrelating with interest in physics learning are gender, perceived relevance, contents and contexts of physics, and teaching methods. Finnish ninth grade secondary school pupil interest in physics in different contexts was investigated with a survey conducted in connection with the international ROSE project. The sample consisted of 3626 pupils (median age 15 in 61 schools. Means of all items that belong to school physics context for both girls and boys were under the middle of the scale. The most interesting things (especially for girls were connected with human being and the less interesting (especially for girls were connected in artefacts and technological processes. Astronomical context was rather interesting for both genders. The main message of the study is that interesting new curricular approaches and textbooks can be developed by combining technological and human or astronomical contexts.

    Fractals are self-similar structures or patterns that repeat at increasingly fine magnifications. Research has revealed fractal patterns in many natural and physiological processes. This article investigates pupillary size over time to determine if their oscillations demonstrate a fractal pattern. We predict that pupil size over time will fluctuate in a fractal manner and this may be due to either the fractal neuronal structure or fractal properties of the image viewed. We present evidence that low complexity fractal patterns underlie pupillary oscillations as subjects view spatial fractal patterns. We also present evidence implicating the autonomic nervous system's importance in these patterns. Using the variational method of the box-counting procedure we demonstrate that low complexity fractal patterns are found in changes within pupil size over time in millimeters (mm) and our data suggest that these pupillary oscillation patterns do not depend on the fractal properties of the image viewed.

  6. Pupil size following dark adaptation in patients with retinitis pigmentosa

    Directory of Open Access Journals (Sweden)

    Berezovsky A.

    2001-01-01

    Full Text Available According to the equivalent light hypothesis, molecular defects in the photoreceptor lead to a continuous activation of the photoreceptor cascade in a manner equivalent to real light. The consequences in diseases such as retinitis pigmentosa (RP are as disruptive to the cells as real light. Two forms of the equivalent light hypothesis can be distinguished: strong - mutations in rhodopsin or other cascade proteins in some forms of RP continuously excite the visual phototransduction cascade; weak - disruption of outer segments in all patients with RP eliminates circulating dark current and blocks neurotransmitter release in a manner similar to real light. Both forms of the equivalent light hypothesis predict that pupils of patients with RP will be constricted like those of normal subjects in the light. The purpose of this study was to test the equivalent light hypothesis by determining whether steady-state pupil diameter following full dark adaptation is abnormally small in any of a sample of patients with RP. Thirty-five patients with RP and 15 normal subjects were tested. Direct steady-state pupillometric measures were obtained from one eye in a full-field dome after 45 min of dark adaptation by videotaping the pupil with an infrared camera. Mean pupil diameter in the dark was comparable (t = -0.15, P = 0.88 between patients with RP (6.85 ± 0.58 mm and normal subjects (6.82 ± 0.76 mm. The results of the present study are clearly counter to the prediction of the second (weaker form of the equivalent light hypothesis.

  8. Forecasting transient sleep episodes by pupil size variability

    2017-09-01

    Full Text Available The ability to predict when a person is about to fall asleep is an important challenge in recent biomedical research and has various possible applications. Sleepiness and fatigue are known to increase pupillary fluctuations and the occurrence of eye blinks. In this study, we evaluated the use of the pupil diameter to forecast sleep episodes of short duration (>1s. We conducted multi-channel physiological and pupillometric recordings (diameter, gaze position in 91 healthy volunteers at rest in supine position. Although they were instructed to keep their eyes open, short sleep episodes were detected in 20 participants (16 males, age: 26.2±5.6 years, 53 events in total. Before each sleep event, pupil size was extracted in a window of 30s (without additional sleep event. Mean pupil diameter and its standard deviation, Shannon entropy and wavelet entropy in the first half (15s were compared to the second half of the window (15s. Linear and nonlinear measures demonstrated an elevation of pupil size variability before sleep onset. Most obviously, WE and SD increased significantly from 0.054±0.056 and 0.38±0.16 mm to 0.113±0.103 (T(102=2.44, p<0.001 and 0.46±0.18 mm (T(104=3.67, p<0.05 in the second half of each analysis window. We were able to identify 83% of the pre-sleep segments by linear discriminant analysis. Although our data was acquired in an experimental condition, it suggests that pupillary unrest might be a suitable predictor of events related to transient sleep or inattentiveness. In the future, we are going to involve the other recorded physiological signals into the analysis.

    2012-09-05

    As part of our research programme into facilitating improved ways of communicating with patients, especially about more sensitive clinical issues, we have been investigating whether there are any non-verbal methods that might aid this process. One such approach is to ask patients to choose a color in response to a particular question, for instance about health or psychological status, and for this purpose we developed the Manchester Color Wheel (MCW). This instrument consists of positive, neutral and negative colors and its validation in normal adults and those with anxiety or depression showed that it is responsive to change and reproducible. It also has the capacity to identify a positive frame of mind. We concluded that it might be a particularly useful instrument in adolescents and therefore this study aimed to validate it in a secondary school. 620 pupils (aged 11-17 years, mean age 14.0 years, 298 (48.1%) males, 322 (51.9%) females) at Sale Grammar School in Greater Manchester were asked to relate their mood to a MCW color and also complete the Hospital Anxiety Depression (HAD) questionnaire. To give these pupils an experience in science, 197 were divided into four subgroups for an 'experiment' to ascertain whether, compared to controls, a change in mood color choice could be induced by participation in sport, music or art activities. Although mood color and HAD depression score are unlikely to be measuring exactly the same psychological state, a negative mood color was chosen by 62.5% of HAD depressed compared to only 14.5% of HAD normal pupils (p color was chosen by 48.9% of normal and only 18.8% of depressed pupils (p colors which reached significance for sport and music. This study confirms the potential utility of the MCW to rapidly and easily assess a variety of health issues in large populations, including adolescents. Some of our results should also be of interest to educationalists.

    Video-based eye tracking relies on locating pupil center to measure gaze positions. Although widely used, the technique is known to generate spurious gaze position shifts up to several degrees in visual angle because pupil centration can change without eye movement during pupil constriction or dilation. Since pupil size can fluctuate markedly from moment to moment, reflecting arousal state and cognitive processing during human behavioral and neuroimaging experiments, the pupil size artifact is prevalent and thus weakens the quality of the video-based eye tracking measurements reliant on small fixational eye movements. Moreover, the artifact may lead to erroneous conclusions if the spurious signal is taken as an actual eye movement. Here, we measured pupil size and gaze position from 23 human observers performing a fixation task and examined the relationship between these two measures. Results disclosed that the pupils contracted as fixation was prolonged, at both small (estimation, in both the ellipse and the centroid methods of pupil tracking. When pupil size was regressed out, the accuracy and reliability of gaze position measurements were substantially improved, enabling differentiation of 0.1° difference in eye position. We confirmed the presence of systematic changes in pupil size, again at both small and large scales, and its tight relationship with gaze position estimates when observers were engaged in a demanding visual discrimination task.

    2017-09-01

    Full Text Available Background:Olanzapine is a highly tolerable and easily affordable atypical antipsychotic drug which has been commonly prescribed in both inpatient and outpatient settings for several mental disorders. Olanzapine overdose is commonly seen in psychiatric patients, who attempt suicide by intoxicating themselves with their own prescribed medications. Increased olanzapine use is associated with increased incidence of overdosing. Case Presentation:We are reporting a case of olanzapine overdosage as a cause of pinpoint pupils and altered sensorium with exclusion of other differentials. The mainstay of managementof olanzapine overdose is general supportive and symptomatic measures. Discussion: Pinpoint pupils with altered sensorium and agitation are always an alarming situation for a clinician, because of differentials like organophosphorus poisoning, pontine hemorrhage and opium overdosing. Due to olanzapine overdosage, similar clinical picture can be confusing in the emergency department and early identification of such cases is helpful to decrease the risk of fatality. Conclusion: This case highlights the significance of olanzapine overdosing as a differential diagnosis for patients presented with altered sensorium and pinpoint pupils in the emergency department. Olanzapine overdosage is associated with high morbidity and mortality. Although there is no specific antidote for olanzapine overdose, appropriate history, assessment and early diagnosis are very useful for the better outcome.

    Full Text Available On a sample of 180 pupils (90 boys, 90 girls of Grammar school Kočevje a frequency of depressive symptoms among adolescents has been researched as well as the impact of gender, learning achievements and age on a depressive reaction phenomenon. A Depressive Moods Scale (Vesel, 1999 has been used, which is very reliable (0,93. A factor analysis has shown that it measures one common factor - depressive reactions, which illustrate 31 % variance. It has been established that one third of pupils are experiencing depressive symptoms frequently or very frequently. Disappointment with oneself because of one's own mistakes is the most frequent, then concentration difficulties and rambling of thoughts, which have been frequently or very frequently experienced by 40 % of pupils. Among five groups of depressive symptoms, cognitive and emotional ones are the most frequent. A high score on the Depressive Moods Scale has been achieved by 10 % of boys and 32 % of girls included in our sample, which shows that girls have more difficulties in experiencing depressive reactions, while learning achievements as well as age do not seem to have any impact on differences in experiencing depressive reactions.

    Adaptive optics, when integrated into retinal imaging systems, compensates for rapidly changing ocular aberrations in real time and results in improved high resolution images that reveal the photoreceptor mosaic. Imaging the retina at high resolution has numerous potential medical applications, and yet for the development of commercial products that can be used in the clinic, the complexity and high cost of the present research systems have to be addressed. We present a new method to control the deformable mirror in real time based on pupil tracking measurements which uses the default camera for the alignment of the eye in the retinal imaging system and requires no extra cost or hardware. We also present the first experiments done with a compact adaptive optics flood illumination fundus camera where it was possible to compensate for the higher order aberrations of a moving model eye and in vivo in real time based on pupil tracking measurements, without the real time contribution of a wavefront sensor. As an outcome of this research, we showed that pupil tracking can be effectively used as a low cost and practical adaptive optics tool for high resolution retinal imaging because eye movements constitute an important part of the ocular wavefront dynamics.

    Veal, M L

    1992-03-01

    Case study design was used in this investigation of the pupil assessment theories of two middle school physical education teachers whose program was identified as a good program in which pupil assessment was taking place. An assumption guiding the study was that teachers' actions are rational and are designed to produce desired results. Therefore, a comparison is made only between two theories of action (espoused and enacted) rather than between theory and practice. Informal and semistructured interviews were employed to elicit teachers' espoused theories, and enacted theories were identified during field visits over a semester in which classes were observed and school documents examined. Teachers' theories of assessment are identified for the categories of participation, effort, and improvement; grading; written tests; fitness testing; performance tests; and formative recordkeeping. Espoused and enacted theories are then examined for congruency. The highest level of incongruency was found in the areas of performance tests and formative recordkeeping. Barriers to the use of pupil assessment techniques in this program include organizational, knowledge, and contextual factors. Change in the assessment practices of secondary teachers may be facilitated, however, through the identification and examination of teachers' theories of assessment by both preservice and inservice teachers.

    To observe pupil behaviour on school buses in Israel and identify hazards as a basis for improving school bus safety. Data on student, bus driver and chaperone behaviours and on hazards associated with school buses, bus loading zones and bus stops were collected during an observational study conducted on school buses in rural communities in Israel. This report focuses on observations of student behaviour during school bus rides. Future reports will discuss the other findings. Student behaviours were assessed by means of chi(2) tests and logistic regression models. Observations were made on 362 rides on 125 buses on which 11 000 pupils travelled to and from school. Seatbelt use among the pupils was limited: on 23% of the rides all pupils fastened seatbelts, while on 42% none did. Seatbelt use was more frequent among primary school pupils than among older pupils. Pupil behaviours, such as rowdiness, noisiness, conflicts between pupils and not remaining seated were observed. These and other unsafe behaviours were more frequent on afternoon bus rides (odds ratio, OR: 3.2, 95% confidence interval, CI: 2.1-5.3), on routes with 5+ bus stops (OR: 4.1; 95% CI: 2.5-6.5) and on rides with primary school pupils (OR: 1.8; 95% CI: 1.2-2.9). Without enforcement, government regulations and seatbelt availability on school buses are not enough to ensure seatbelt usage among pupils. Bus drivers cannot be expected to enforce seatbelt use and deal with pupil misconduct while also driving safely. Innovative strategies for improving pupil behaviour on school buses are needed to increase pupil safety.

    This paper explores differences in how primary care doctors process the clinical presentation of depression by African American and African-Caribbean patients compared with white patients in the US and the UK. The aim is to gain a better understanding of possible pathways by which racial disparities arise in depression care. One hundred and eight doctors described their thought processes after viewing video recorded simulated patients presenting with identical symptoms strongly suggestive of depression. These descriptions were analysed using the CliniClass system, which captures information about micro-components of clinical decision making and permits a systematic, structured and detailed analysis of how doctors arrive at diagnostic, intervention and management decisions. Video recordings of actors portraying black (both African American and African-Caribbean) and white (both White American and White British) male and female patients (aged 55 years and 75 years) were presented to doctors randomly selected from the Massachusetts Medical Society list and from Surrey/South West London and West Midlands National Health Service lists, stratified by country (US v.UK), gender, and years of clinical experience (less v. very experienced). Findings demonstrated little evidence of bias affecting doctors' decision making processes, with the exception of less attention being paid to the potential outcomes associated with different treatment options for African American compared with White American patients in the US. Instead, findings suggest greater clinical uncertainty in diagnosing depression amongst black compared with white patients, particularly in the UK. This was evident in more potential diagnoses. There was also a tendency for doctors in both countries to focus more on black patients' physical rather than psychological symptoms and to identify endocrine problems, most often diabetes, as a presenting complaint for them. This suggests that doctors in both countries

  10. Pupil Dilation in the Simon Task as a Marker of Conflict Processing

    Directory of Open Access Journals (Sweden)

    Henk eVan Steenbergen

    2013-05-01

    Full Text Available Cognitive demands in response conflict paradigms trigger negative affect and avoidance behavior. However, not all response conflict studies show increases in physiological indices of emotional arousal, such as pupil diameter. In contrast to earlier null-results, this study shows for the first time that small (about 0.02 mm conflict-related pupil dilation can be observed in a Simon task when stimuli do not introduce a light reflex. Results show that response-conflict in Simon trials induces both pupil dilation and reaction-time costs. Moreover, sequential analyses reveal that pupil dilation mirrors the conflict-adaptation pattern observed in reaction time. Although single-trial regression analyses indicated that pupil dilation is likely to reflect more than one process at the same time, in general our findings imply that pupil dilation can be used as an indirect marker of conflict processing.

    2008-12-01

    Full Text Available Analyses the novel 'Brown girl, brownstones' (1959 by Paule Marshall. Author argues that this novel offers a complex and nuanced understanding of how Caribbean migration impacts upon cultural identity, and how this cultural identity is dynamically produced, rather than static. He describes how the novel deals with Barbadian migrants to the US in the 1930s and 1940s, and further elaborates on how through this novel Marshall problematizes common dichotomies, such as between the public and the private, and between racial (black and ethnic (Caribbean identity. Furthermore, he indicates that Marshall through her representation of the Barbadian community, foregrounds the central role of women in the production of Caribbean identity in the US. In this, he shows, Bajan women's talk from the private sphere is very important. Further, the author discusses how the Barbadian identity is broadened to encompass Caribbean and African Americans in the novel, thus creating transnational black diaspora connections, such as by invoking James Baldwin and Marcus Garvey.

    To explore pupils' and teachers' experiences of physical education (PE). A qualitative investigation employing semistructured interviews. Self Determination Theory was used as a guiding theory and Template Analysis was used to analyse the data. A secondary school in the North East of England. 14 pupils (aged 13 and 14, boys and girls) with a range of self-perceived competencies regarding PE and four PE teachers of the pupils (3 male, 1 female). (1) Attitudes and perceptions of PE pupils regarding their experiences of compulsory school PE lessons. (2) PE teachers' experiences of teaching PE. Key results from pupils and teachers suggest pupils enjoy participation in PE when they feel competent, in control and supported by others. Feeling competent depended on (1) the activity within PE and (2) the pupils perceived physical capabilities/aptitude. Feeling in control related to (1) having a choice of activities, (2) being able to set exertion levels and (3) control over clothes worn while taking part. Relationships within pupil groups and between pupils and teachers were perceived as important. Teachers could positively influence their pupils' enjoyment by understanding and supporting their personal goals, as opposed to dictating and controlling what they did and for how long, and by promoting a non-threatening atmosphere between pupils. Rising obesity levels and concerns over the fitness of children and young people has returned the focus of PE to its potential as a vehicle for promoting health. This study suggests schools and PE teachers in particular can positively influence the PE experience of both boys and girls by providing more choice of activities and letting pupils make their own decisions based on their personal needs.

    Full Text Available Education in the Czech Republic in accordance with the current legislation enables the children, pupils and students with disabilities to have equal access to education, where content, forms and methods meet the educational requirements of those individuals. From the point of view of the health aspect in their adulthood, especially the educational fields of health and physical education are crucial for pupils. The purpose of this study was to compare the dimensions of emotional reactions of pupils who are deaf or hard of hearing in schools for the deaf and those compare with integrated pupils who are deaf or hard of hearing at basic school (grades 6th-9th enrolled in physical education classes. It was also compared preferences in leisure time activities and the knowledge of pupils who are deaf or hard of hearing in both schools settings with regard to sport and sports activities related to this community. Participants in this study were integrated pupils who are deaf or hard of hearing (n = 7, whose average age was 14.43 ± 1.27 years. These pupils were compared with pupils from schools for the deaf (n = 32; age 15.19 ± 1.24 years. At school for the deaf who was evaluated separately, were included 27 pupils who are deaf or hard of hearing (n = 27, age 15.41 ± 1.28 years. The standardized questionnaire DEMOR (dimensions of emotional reactions was used in data collection. This questionnaire was adapted with regards to conditions of pupils who are deaf or hard of hearing. In presented study positive relationships to physical education in pupils who are deaf or hard of hearing were found. Only at schools for the deaf (not counting school for the deaf, which was evaluated separately strongly lower negative relationships than in pupils from general schools were found. Those negative attitudes of pupils to physical education could be related to the followings: lower physically fitness and the impact of teachers (these variables were not tested in

    The link between inappropriate parenting style and both bullying and victimization is well documented. However, it is not clear as to which kind of parenting style is associated with victimization. Furthermore, no studies have yet been conducted regarding the role of parental stress in bullying and victimization. This study aimed to examine the role of parenting styles and maternal stress in pupils' bullying and victimization. A total of 300 primary school pupils, enrolled in fourth and fifth grades, participated in the study. Initially, 100 noninvolved pupils were randomly selected using a multistage cluster sampling method. Then using a screening method, 100 bully pupils and 100 victimized peers were selected. Olweus Bullying Scale and teacher nomination were administered for screening these pupils. Baumrind Parenting Style Questionnaire and revised version of Abidin Parental Stress Index (short form) were also applied to all pupils in the study. Data were analyzed using discriminant function analysis. The findings showed that (a) with regard to parenting styles, significant differences were found among groups. Authoritarian parenting style could significantly predict pupils' bullying behavior, whereas victimization was predictable in families with permissive parenting style. In addition, noninvolved pupils were predicted to have authoritative parenting style. (b) Considering maternal stress, significant differences were observed across groups. Parents of bullies and victims were predicted to have higher maternal stress than noninvolved pupils. The implications of the study in relation to the role of mothers in bullying and victimization are discussed.

  19. Exit pupil expander: image quality performance enhancements and environmental testing results

    2003-09-01

    The numerical aperture of the light emanating from display pixels in a given display system determines the exit pupil size. In retinal scanning displays, the exit pupil is defined by the scanner optics, creating a rastered, projected image at an intermediate plane, typically resulting in an exit pupil approximately the size of an eye's pupil. Positional freedom of the eye and relative display placement define the required expansion of the limited input NA for producing the desired exit pupil size for the display system. Currently Microvision utilizes an optical element comprised of two Microlens Arrays (MLAs) in tandem to expand the NA. The dual-MLA system has demonstrated exit pupil size that is independent of color; and uniformity of the beamlet structure is quite Top-Hat like. To further improve the perceived image quality, Microvision has now refined the optical system to minimize interference effects in the Exit Pupil plane that were caused by the coherent nature of the light source. We describe here a single refractive double-sided aspheric element that diminishes this interference effect by converting an input Gaussian beam profile to a Top-Hat profile. We also discuss the theory behind the use of a Gaussian-to-Top-Hat Converter, the tradeoffs associated with its use, as well as experimental results showing the uniformity improvements when using a Top-Hat converter element in conjunction with the MLA-based Exit Pupil Expander. In addition, we report the progress of environmental testing of the Exit Pupil Expander (EPE).

    2006-05-01

    This paper reports research about upper secondary school pupils' views about science investigations in school. Although researchers, teachers and examiners have expressed opinions about investigative work in science, there have been relatively few studies of pupils' experiences. The present study identified pupils' concerns about the limited time available, timing of the investigations, lack of familiarity with apparatus and the association of investigation almost exclusively with assessment, all factors which contributed to stress. One exceptional school apart, pupils perceived the teacher's role as a didactic supporter of strategies to maximise performance for assessment. We discuss these views and examine the potential for putting policy into practice.

  1. Is Tadpole Pupil in an Adolescent Girl Caused by Denervation Hypersensitivity?

    2017-06-01

    Tadpole pupil is a rarely encountered phenomenon caused by episodic, segmental iris dilator muscle spasm of short duration (2-15 minutes), occurring in clusters without a known precipitating factor. It has most commonly been described in women aged 28 to 48 years. A few hypotheses on pathogenesis have been discussed but none has been proved. Here, we present an adolescent girl with bilateral tadpole pupil that appeared during physical exercise. This is the first pediatric case of tadpole pupil, not caused by preceding surgery, to be published. Based on (1) this case in which tadpole pupil developed when the norepinephrine level rose during exercise, (2) the high ratio of patients with tadpole pupil who concurrently have or later develop Horner syndrome, in which denervation hypersensitivity is well described, (3) a previous report of a patient with both tadpole pupil and Horner syndrome who had denervation hypersensitivity on pharmacological testing, (4) a 29-year-old man with unilateral tadpole pupil induced by exercise, and (5) a 19-year-old man with bilateral tadpole pupil and possible autonomic neuropathy, we suggest denervation hypersensitivity as a probable pathogenic mechanism causing tadpole pupil. In addition, a suggestion for investigations to be performed in future pediatric cases is provided. Georg Thieme Verlag KG Stuttgart · New York.

  2. Selection, Language Heritage, and the Earnings Trajectories of Black Immigrants in the United States

    Research suggests that immigrants from the English-speaking Caribbean surpass the earnings of U.S.-born blacks approximately one decade after arriving in the United States. Using data from the 1980–2000 U.S. censuses and the 2005–2007 American Community Surveys on U.S.-born black and non-Hispanic white men as well as black immigrant men from all the major sending regions of the world, I evaluate whether selective migration and language heritage of immigrants’ birth countries account for the documented earnings crossover. I validate the earnings pattern of black immigrants documented in previous studies, but I also find that the earnings of most arrival cohorts of immigrants from the English-speaking Caribbean, after residing in the United States for more than 20 years, are projected to converge with or slightly overtake those of U.S.-born black internal migrants. The findings also show three arrival cohorts of black immigrants from English-speaking African countries are projected to surpass the earnings of U.S.-born black internal migrants. No arrival cohort of black immigrants is projected to surpass the earnings of U.S.-born non-Hispanic whites. Birth-region analysis shows that black immigrants from English-speaking countries experience more rapid earnings growth than immigrants from non-English-speaking countries. The arrival-cohort and birth-region variation in earnings documented in this study suggest that selective migration and language heritage of black immigrants’ birth countries are important determinants of their initial earnings and earnings trajectories in the United States.

    Black women bear a disproportionate burden of HIV/AIDS in North America. The purpose of this investigation was to explore Black Canadian women's perspectives on HIV risk and prevention. Four 90-minute focus groups (n=26) and six key informant interviews were conducted in Toronto with Black women of African and Caribbean descent and low socioeconomic status. Data analysis revealed a number of potent barriers to existing HIV preventive interventions: stigma, cultural disconnections, lack of engagement of Black religious institutions, and multiple intersecting forms of discrimination. Recommended HIV prevention opportunities included the Black church, mainstreaming, health care providers, and ethno-specific agencies. HIV prevention strategies for North American Black women, rather than focusing on HIV and individual risk behaviors, may benefit from a primary focus on social and structural factors (e.g., promoting gender equality, economic opportunity, women-controlled prevention technologies and combating racism in health care) thereby integrating HIV prevention into the larger context of community health and survival.

    Cigarette smoking poses a major public health problem that disproportionately affects Blacks and men. Religious attendance has been shown to be positively associated with health promotion and disease prevention among the Black population. In light of this evidence, this study examined if a similar relationship could be found for religious attendance and smoking in Black men. The National Survey of American Life (NSAL) study sampled 1,271 African American men and 562 Black Caribbean men. Multivariate logistic regression was used to determine the association between religious attendance and cigarette smoking. After adjusting for age, marital status, household income, education, foreign born status, importance of prayer and major stress, men who reported attending religious services almost every day (odds ratio (OR) = 0.21, 95% confidence interval (CI) = 0.07, 0.62) and weekly (OR = 0.47, 95% CI = 0.29, 0.77) had lower odds of being a current smoker compared to men who reported never attending religious services. Conclusions/Importance: Findings suggest a health benefit in attending religious services on cigarette smoking among Black men in a nationally representative sample. In spite of lower church attendance in Black men in general, our results demonstrate that religious service attendance may still serve as a buffer against cigarette use. Given the emergent attention on faith-based health promotion among men, this conclusion is relevant and timely.

    Full Text Available Abstract Background As part of our research programme into facilitating improved ways of communicating with patients, especially about more sensitive clinical issues, we have been investigating whether there are any non-verbal methods that might aid this process. One such approach is to ask patients to choose a color in response to a particular question, for instance about health or psychological status, and for this purpose we developed the Manchester Color Wheel (MCW. This instrument consists of positive, neutral and negative colors and its validation in normal adults and those with anxiety or depression showed that it is responsive to change and reproducible. It also has the capacity to identify a positive frame of mind. We concluded that it might be a particularly useful instrument in adolescents and therefore this study aimed to validate it in a secondary school. Methods 620 pupils (aged 11–17 years, mean age 14.0 years, 298 (48.1% males, 322 (51.9% females at Sale Grammar School in Greater Manchester were asked to relate their mood to a MCW color and also complete the Hospital Anxiety Depression (HAD questionnaire. To give these pupils an experience in science, 197 were divided into four subgroups for an ‘experiment’ to ascertain whether, compared to controls, a change in mood color choice could be induced by participation in sport, music or art activities. Results Although mood color and HAD depression score are unlikely to be measuring exactly the same psychological state, a negative mood color was chosen by 62.5% of HAD depressed compared to only 14.5% of HAD normal pupils (p  Conclusion This study confirms the potential utility of the MCW to rapidly and easily assess a variety of health issues in large populations, including adolescents. Some of our results should also be of interest to educationalists.

    Full Text Available This paper describes how gender and age affect Japanese pupils’ motivation for learning English and their attitudes to communication with people from different cultures. A new foreign language curriculum was introduced to Japanese elementary schools in 2011. Although each school can officially choose any foreign language in its own right, most elementary schools are now conducting English activity. However, as most homeroom teachers lack both experiences and qualifications for teaching English, this activity puts them under pressure. In addition, the number of foreign assistant language teachers (ALTs is not sufficient in most elementary schools. The writer surveyed fifth and sixth grade pupils’ motivation and their communicative attitudes in Japan during 2010, before the new course program, “foreign language activities,” began in 2011. The data were collected from three elementary schools in Japan via a questionnaire. The items on the questionnaire are related to motivational attitudes, orientations (reasons for studying a foreign language, communicative attitudes and some other variables relevant to learning foreign languages. The main focus of this study is to examine motivational and attitudinal variables among the pupils with regard to learning English, especially gender and age effects on these variables. The results show that girls generally have higher scores on motivation and communicative attitudes. Most previous studies have also shown that girls generally have a positive attitude toward learning a foreign language. This study argues that the reason behind this positive attitude toward learning English is due to their positive attitude toward communication in general. With regard to the age, there are a few differences between two school grades. As there is only one year difference in age between fifth and sixth grade pupils, the result is to be expected. The study suggests that Japanese elementary schools face a number of

    Full Text Available The new development agendas confirmed in the year 2015 evidence an increased global interest in cities and urban challenges. In Latin America and the Caribbean, cities have long been an established topic of study and debate. This exploration gives a brief overview of current research on urban development in the region and suggests fruitful avenues for future research. Following different ideological trends in twentieth-century urban studies, we currently see more pragmatic frameworks and a belief in technocratic solutions. Some scholars consider Latin American and Caribbean cities to be the world’s new signposts in urban development, given their role as sites of innovations in politics, architecture and urban design; we see potential here for urban scholars of the region to move beyond technocratic language. In addition, we argue for an area studies approach to these cities that uses the framework of the region as a heuristic device to unsettle global urbanist epistemologies that privilege North-to-South mobilities in both policy and theory. Resumen: El desarrollo urbano latinoamericano y caribeñoLas nuevas agendas de desarrollo confirmadas en el año 2015 reflejan un mayor interés mundial en las ciudades y en los retos urbanos.

    Large, recent migration streams from the non-Hispanic Caribbean islands and Africa have increased the share of U.S. blacks born outside of the U.S. Little is known about health patterns in these foreign-born populations. The purpose of this study is to compare obesity levels among self-identified U.S. blacks across birth regions and examine potential explanations for subgroup differences. Data were from the 2000-2013 National Health Interview Surveys. Three birthplace subgroups were examined: individuals born in the U.S., Caribbean/South America, and Africa, aged 25-59 years. Data were analyzed in 2013-2014. Compared to U.S.-born participants, foreign-born participants had significantly lower obesity (BMI ≥30) odds. The AORs were 0.51 (Caribbean/South American-born, 95% CI=0.44, 0.58) and 0.41 (African-born, 95% CI=0.34, 0.50) with reference to U.S.-born individuals. Education, income, and cigarette smoking did not explain the favorable weight pattern of the foreign born. Among the foreign born, those residing in the U.S. for ≥15 years had 51% (95% CI=10%, 108%) higher obesity odds compared with those residing for <5 years. No statistically significant differences in obesity odds between those born in the Caribbean/South America and Africa were detected. Foreign-born blacks generally had lower obesity levels compared to their U.S.-born counterparts, which was not explained by SES or smoking behaviors. Despite this advantage, obesity prevalence among foreign-born black women was around 30%, suggesting that obesity poses a significant health risk this population.

    2003-01-01

    Methods and results of searching for stellar mass black holes in binary systems and for supermassive black holes in galactic nuclei of different types are described. As of now (June 2002), a total of 100 black hole candidates are known. All the necessary conditions Einstein's General Relativity imposes on the observational properties of black holes are satisfied for candidate objects available, thus further assuring the existence of black holes in the Universe. Prospects for obtaining sufficient criteria for reliably distinguishing candidate black holes from real black holes are discussed. (reviews of topical problems)

    The Caribbean region is considered to be at risk for avian influenza (AI) due to a large backyard poultry system, an important commercial poultry production system, the presence of migratory birds, and disparities in the surveillance systems. The Caribbean Animal Health Network (CaribVET) has developed tools to implement AI surveillance in the region with the goals to have 1) a regionally harmonized surveillance protocol and specific web pages for AI surveillance on www.caribvet.net, and 2) an active and passive surveillance for AI in domestic and wild birds. A diagnostic network for the Caribbean, including technology transfer and AI virus molecular diagnostic capability in Guadeloupe (real-time reverse transcription-polymerase chain reaction for the AI virus matrix gene), was developed. Between 2006 and 2009, 627 samples from four Caribbean countries were tested for three circumstances: importation purposes, following a clinical suspicion of AI, or through an active survey of wild birds (mainly waders) during the southward and northward migration periods in Guadeloupe. None of the samples tested were positive, suggesting a limited role of these species in the AI virus ecology in the Caribbean. Following low pathogenic H5N2 outbreaks in the Dominican Republic in 2007, a questionnaire was developed to collect data for a risk analysis of AI spread in the region through fighting cocks. The infection pathway of the Martinique commercial poultry sector by AI, through introduction of infected cocks, was designed, and recommendations were provided to the Caribbean Veterinary Services to improve cock movement control and biosecurity measures. The CaribVET and its organization allowed interaction between diagnostic and surveillance tools on the one hand and epidemiologic studies on the other, both of them developed in congruence with regional strategies. Together, these CaribVET activities contribute to strengthening surveillance of avian influenza virus (AIV) in the

    Full Text Available The order Amphipoda is one of the most diverse within Peracarids, and comprises 6 950 described marine species. Amphipod research in the Caribbean Sea began in the late 1 800s, but has increased significantly since 1 980. In this study, we analized the amphipod biodiversity (Caprellidea, Gammaridea, Hyperiidea, and Ingolfiellidea of the Caribbean Sea. For this, we compiled available data on species diversity of marine amphipods (data bases: WoRMS and OBIS and published species lists into a comprehensive taxonomic list by country for the ecoregions of the Caribbean. Additionally, we analized the relative contribution of each country to regional diversity and the rate of discovery of new species. The Caribbean amphipod fauna is composed of 535 species within 236 genera and 73 families for the higher taxon. The Western Caribbean ecoregion holds the largest diversity (282 species, while the Eastern Caribbean recorded the lowest one (73. Mexico and Venezuela recorded the largest number of species with 266 and 206, respectively. Twelve countries had less than 50 species. The richest suborder is the Gammaridea with 381 species followed by the suborder Hyperiidea with 116. From the total of 535 amphipod species reported for the Caribbean region, 218 have the Caribbean as the holotype locality, and 132 are endemic (about 25% of the total. Areas of higher diversity seem to be concentrated along the Mexican Caribbean, Cuba and the Northern coast of South America (Venezuela-Colombia; however, such pattern is most likely reflecting local collection efforts and taxonomic expertise rather than actual distribution. Knowledge of amphipod species is mostly limited to shallow, near-shore waters, with little information available on the deep sea fauna. Regional research priorities for this group should be focused on completing shallow water coastal inventories of species in Central America and the Greater and Lesser Antilles. In addition, sampling the deep sea

    2013-06-01

    Full Text Available This paper presents a broad overview of historical and contemporary gender and social class relations in the British, French, and Spanish Caribbean islands focusing primarily on Afro-Caribbean people. It begins with a discussion of gendered relations during slavery and then investigates gender roles post emancipation. Next, multiple aspects of contemporary West Indian family life are addressed including the prevalence of matrifocal households and child shifting. The important roles played by Caribbean female household heads are discussed in the context of patriarchy. Highlights include the significance of the maternal role over the marital, socializing youth, particular negative expectations each sex holds of the other, customary sexual behavior, as well as common relationship types. Varying aspects of women’s behavior according to social class is touched upon followed by a brief synopsis of the status of Caribbean women on measures of educational and work force participation rates; finally, a summary of the dearth of active women’s movements in the region is addressed. The paper provides an introduction to the intimate and working lives of Caribbean women and men.

  5. Toward a Caribbean psychology: an African-centered approach.

    Sutherland, Marcia Elizabeth

    2011-01-01

    Although the Americas and Caribbean region are purported to comprise different ethnic groups, this article’s focus is on people of African descent, who represent the largest ethnic group in many countries. The emphasis on people of African descent is related to their family structure, ethnic identity, cultural, psychohistorical, and contemporary psychosocial realities. This article discusses the limitations of Western psychology for theory, research, and applied work on people of African descent in the Americas and Caribbean region. In view of the adaptations that some people of African descent have made to slavery, colonialism, and more contemporary forms of cultural intrusions, it is argued that when necessary, notwithstanding Western psychology’s limitations, Caribbean psychologists should reconstruct mainstream psychology to address the psychological needs of these Caribbean people. The relationship between theory and psychological interventions for the optimal development of people of African descent is emphasized throughout this article. In this regard, the African-centered and constructionist viewpoint is argued to be of utility in addressing the psychological growth and development of people of African descent living in the Americas and Caribbean region.

  6. Insights Into Caribbean Lithospheric Structure From S Wave Receiver Functions

    BOLIVAR (Broadband Ocean-Land Investigation of Venezuela and the Antilles arc Region) was aimed at investigating the interplay between the lithospheric and asthenospheric mantle of the Caribbean and the South America plates. The oblique collision of the Caribbean plate migrating eastwards has created a complicated deformation zone with strike-slip, compressional and extensional structures along the Caribbean and South America boundary. Earlier results with P receiver functions revealed strong variations in crustal thickness ranging from 15 km beneath the Caribbean Sea to 55 km beneath Venezuela. However, one of the fundamental questions not yet resolved concerns the thickness of the lithosphere in this region. Using the S wave receiver function technique, we analyzed seismograms from some 100 events at epicentral distances of 55-125 degree. The seismograms were rotated and deconvolved to isolate S-to-P conversions from the incident S wave. These were subsequently stacked after their respective conversion points and mapped into the subsurface. A strong negative phase is associated with the S-to-P conversion from the base of the lithosphere. Analysis of these data is ongoing, but we expect to see large variation in lithospheric thickness as the BOLIVAR array spans the transition from the Caribbean with OBS stations to the interior of South America (Guyana Shield).

  7. A quasi-decadal cycle in Caribbean climate

    2009-07-01

    Climatic variables in the period from 1951 to 2000 are analyzed across the tropics from the East Pacific to Africa. A quasi-decadal mode is isolated using singular value decomposition (SVD) applied to monthly smoothed and detrended rainfall, sea surface temperature (SST), sea level pressure (SLP), and 200 hPa zonal (U) wind anomalies. Seven- to 10-year cycles in Caribbean rainfall are revealed as the dominant mode (50% variance) and are found to be related to a mode of tropical variability that is distinct from previously known global signals. Sources of this signal include east Atlantic SST and the northern subtropical ridge, which modulate upwelling off Venezuela. SVD analysis of daily rainfall suggests interaction between annual and quasi-decadal signals, with northern summer convection as a driver. The second mode of Caribbean rainfall variability derives from the east Pacific El Niño Southern Oscillation (ENSO, 21% variance) that is expressed as an east-west dipole of convection across the Caribbean. Composite analysis of rainfall for high and low phases of the quasi-decadal cycle reveals a corresponding signal that extends from the eastern Pacific Ocean across the Caribbean and West Africa to India. The southern Hadley cell spins up during wet phase, and the ITCZ migrates northward. This hemispheric-scale anomaly brings pulses of convection to the Caribbean. Impacts of the quasi-decadal cycle on socioeconomic resources are investigated.

  8. Dog Food Consumption in the Caribbean: A Baseline Study

    Fielding, William J.

    2013-10-01

    Full Text Available Dogs in the Caribbean have been traditionally viewed as low maintenance pets which are fed leftovers from the household. Changes in the lifestyle of Caribbean families have resulted in changes in their eating patterns. These changes can be expected to have consequences for the feeding of dogs, which may require households to switch to commercial dog food. This paper reports the finding of a survey of groups involved with pets and animal welfare in the Caribbean conducted on behalf of the Pet Food Institute, a non-profit industry association. The study examined perspectives on how dogs are fed in the Caribbean and activities conducted to educate pet owners and the public. Use of household scraps and commercial dog food was associated with household income, except in the case of some high income dependent territories. The findings indicate that while many animal welfare groups in the Caribbean provide educational programs, not all of these provide recommendations on feeding pets and so they neglect to provide information on an important aspect of animal welfare.

  9. ADRIAN HATOS, School Performance and Language of Hungarian Ethnic Pupils

    Full Text Available One of the thorniest issues of the linguistic policies in North-Western Transylvania was the establishment of linguistic arrangements in the mandatory education system. Supported also by arguments which refer to the equal opportunity rule, native language education for ethnic minority children, concerning especially the Hungarian language, has flourished both in mixed schools, and in schools that are segregated in terms of the teaching language. This article assesses the effects that the various linguistic contexts in which a Hungarian teenager in the region studies can have on his/her performance in school, compared to the performance of his/her colleagues who study in Romanian. I start from two hypotheses: linguistic shortcoming and opposition culture. The hierarchical linear regression modeling of the average of school results scores in the seventh grade, on a sample of over 3 700 pupils in the eighth grade in Bihor County, indicates a significant and systematic disadvantage of Hungarian pupils, although small as an absolute value, irrespective of the linguistic arrangement. Moreover, both the linguistic disadvantage thesis and the opposition culture model can be supported, although the results are not conclusive from this point of view.

    The Five Digits Test (FDT) is a Stroop paradigm test that aims to evaluate executive functions. It is composed of four parts, two of which are related to automatic and two of which are related to controlled processes. It is known that pupillary diameter increases as the task's cognitive demand increases. In the present study, we evaluated whether the pupillary diameter could distinguish cognitive effort between automated and controlled cognitive processing during the FDT as the task progressed. As a control task, we used a simple reading paradigm with a similar visual aspect as the FDT. We then divided each of the four parts into two blocks in order to evaluate the differences between the first and second half of the task. Results indicated that, compared to a control task, the FDT required higher cognitive effort for each consecutive part. Moreover, the first half of every part of the FDT induced dilation more than the second. The differences in pupil dilation during the first half of the four FDT parts were statistically significant between the parts 2 and 4 (p=0.023), and between the parts 3 and 4 (p=0.006). These results provide further evidence that cognitive effort and pupil diameter can distinguish controlled from automatic processes.

    We developed techniques to unobtrusively track direction and pupil diameter of radiologists reading a wide variety of films. This study concentrated on mammography since the use of mammograms is important for successful treatment of breast cancer, and we wished to determine how previous studies of eye gaze with lung films relate to the specialized field of mammography. Our objective was to identify eye gaze patterns in mammographic experts as they observe features, such as masses and microcalcification clusters: identification of these patterns could lead to improving the rate of early detection of breast cancer. Our near IR light system successfully tracked eye gaze direction and pupil diameter of mammographic experts evaluating films. The association of long eye gaze dwells with diagnostic accuracy varied with the type of object being viewed. In films with masses, false positive diagnoses were associated with long dwells: this is similar to published results of observing lung nodule diagnosis. In mammograms with microcalcifications, true positive diagnoses were associated with long dwells. The association of prolonged dwells with true positive diagnoses of microcalcifications is a new observation.

    Full Text Available Presented results of physical development of young people. 965 pupils and 438 students participated in research. One measured length and mass of the body, registered cardiorespiratory indexes – cardiac rate at peace and after 20 squats, vital capacity of lungs, breath-holding on inhalation and exhalation. The coefficient of physical development was calculated on a formula taking into account actual and middling population indexes. Gradual development of morphofunctional indexes is set for pupils and students from 7 to 20 years old. Rates of such changes were different both in age-old and sexual groups. It is educed that for boys and girls 7-8 years middling the statistical values of coefficient of physical development exceeded standard indexes. In 9-13 years on a background of further increase of morphofunctional parameters the rates of increase of physical development diminished a bit. From 13 to 16 years the index of coefficient of physical development changed a little, except for an insignificant increase in 14 years. It is shown that in an age-old period 17-20 years a mesosomia prevails for the inspected students. It is educed reliable differences between the values of coefficient of physical development in the groups of boys and girls 17 and 19 years.

    Media have an influence on the human psyche similar to the addictive actions of psychoactive substances or gambling. Computer overuse is claimed to be a cause of psychiatric disturbances such as computer and Internet addiction. It has not yet been recognized as a disease, but it evokes increasing controversy and results in mental disorders commonly defined as computer and Internet addiction. This study was based on a diagnostic survey in which 120 subjects participated. The participants were pupils of three kinds of schools: primary, middle, and secondary school (high school). Information for this study was obtained from a questionnaire prepared by the authors as well as the State-Trait Anxiety Inventory (STAI) and the Psychological Inventory of Aggression Syndrome (IPSA-II). he results confirmed that every fourth pupil was addicted to the Internet. Internet addiction was very common among the youngest users of computers and the Internet, especially those who had no brothers and sisters or came from families with some kind of problems. Moreover, more frequent use of the computer and the Internet was connected with higher levels of aggression and anxiety. Because computer and Internet addiction already constitute a real danger, it is worth considering preventive activities to treat this phenomenon. It is also necessary to make the youth and their parents aware of the dangers of uncontrolled Internet use and pay attention to behavior connected with Internet addiction.

    Human eyes are never completely static even when they are fixing a stationary point. These irregular, small movements, which consist of micro-tremors, micro-saccades and drifts, can prevent the fading of the images that enter our eyes. The importance of researching the fixational eye movements has been experimentally demonstrated recently. However, the characteristics of fixational eye movements and their roles in visual process have not been explained clearly, because these signals can hardly be completely extracted by now. In this paper, we developed a new eye movement detection device with a high-speed camera. This device includes a beam splitter mirror, an infrared light source and a high-speed digital video camera with a frame rate of 200Hz. To avoid the influence of head shaking, we made the device wearable by fixing the camera on a safety helmet. Using this device, the experiments of pupil tracking were conducted. By localizing the pupil center and spectrum analysis, the envelope frequency spectrum of micro-saccades, micro-tremors and drifts are shown obviously. The experimental results show that the device is feasible and effective, so that the device can be applied in further characteristic analysis.

    Discrimination is a common experience for Blacks across various developmental periods. Although much is known about the effect of discrimination on suicidal ideation of adults, less is known about the same association in Black youth. We examined the association between discrimination and suicidal ideation in a national sample of Black youth. We also explored gender and ethnic differences in this association. We used data from the National Survey of American Life-Adolescents (NSAL-A), 2003-2004. In total, 1170 Black adolescents entered the study. This number was composed of 810 African American and 360 Caribbean Black youth (aged 13 to 17 years). Demographic and socioeconomic factors were controls, perceived discrimination was the predictor, and lifetime suicidal ideation was the outcome. Logistic regression was used to test the association between perceived discrimination and suicidal ideation in the pooled sample, as well as based on ethnicity and gender. In the pooled sample of Black youth, higher perceived discrimination was associated with higher odds of suicidal ideation (Odds Ratio (OR) = 1.09; 95% Confidence Interval (CI) = 1.02-1.17). This association was significant net of age, ethnicity, gender, and socioeconomic status. We did not find interactions between perceived discrimination and ethnicity or gender on suicidal ideation. Perceived discrimination was associated with suicidal ideation in African Americans (CI = 1.09; 95% CI = 1.01-1.17) and Caribbean Blacks (CI = 1.16; 95% CI = 1.03-1.32), males (CI = 1.11; 95% CI = 1.00-1.25), and females (CI = 1.08; 95% CI = 1.00-1.16). Discrimination jeopardizes the mental health of Black youth. In a universal pattern, discrimination is associated with suicidal ideation in Black youth. More research is needed on this topic.

    Ngaage, Millie; Agius, Mark

    2016-09-01

    The UK-based AESOP study conducted over a two-year period in three UK sites simultaneously (London, Nottingham, and Bristol), is the largest study to date to conduct a first contact case-control study of psychosis. The study found that rates of schizophrenia were markedly elevated in both African-Caribbean and Black African people, in both sexes and across all age groups. English language literature published up to 2016 was searched. The initial search included: PubMed, The Cochrane Library, and Web of Science. A second search was conducted using Medical Subject Headings (MeSH) and keywords. Studies selected for retrieval were assessed by two independent reviewers. The search yielded eight results, all of which supported the conclusion of an increased incidence of schizophrenia in Black African and Black Caribbean population in the AESOP study. England is a multicultural landscape; multiplicity of cultures makes diagnosis difficult. The lessons we must learn from the AESOP study is the need for transcultural training and the removal of blinding to ethnicity when a large epidemiological study is conducted - psychiatrists need to be cognisant of cultures and aware of the context of symptoms.

    2015-09-01

    Time can be observed as a subjective, as well as an objective phenomenon which is a component of our life, and due to its communicational needs, it is standardized by temporal signs and symbols. The aim of this study was to determine the understanding of basic temporal relations of pupils with hearing impairments. We assumed that the knowledge of basic time relations is a precondition for the acquisition of knowledge that is connected with the understanding of the syllabus in regular school programs. Three groups of pupils have been examined: pupils with hearing impairments who attend the primary school of SUVAG Polyclinic under special condition, integrated hearing impaired pupils with minor additional difficulties who attend regular primary schools in Zagreb with a prolonged expert procedure and pupils of the control group. The subjects have been examined with a measuring instrument constructed by the expert team of the Polyclinic Suvag. Twenty nine subjects have been questioned, chronologically aged between 10 and 12.

  11. The "subjective" pupil old/new effect: is the truth plain to see?

    2013-07-01

    Human memory is an imperfect process, prone to distortion and errors that range from minor disturbances to major errors that can have serious consequences on everyday life. In this study, we investigated false remembering of manipulatory verbs using an explicit recognition task and pupillometry. Our results replicated the "classical" pupil old/new effect as well as data in false remembering literature that show how items must be recognize as old in order for the pupil size to increase (e.g., "subjective" pupil old/new effect), even though these items do not necessarily have to be truly old. These findings support the strength-of-memory trace account that affirms that pupil dilation is related to experience rather than to the accuracy of recognition. Moreover, behavioral results showed higher rates of true and false recognitions for manipulatory verbs and a consequent larger pupil diameter, supporting the embodied view of language.

    2011-10-01

    There is increasing concern about the inappropriate use of alcohol by teenagers and young adults. The objective of this study was to assess the practicality of developing an alcohol education programme for school pupils delivered by medical students. The study design was of a prospective, observational, interventional cohort study. The primary outcomes were the number of schools, school pupils and medical students participating in the programme. Secondary outcomes were quantitative and qualitative measures derived from the feedback received from the participants. Over a three-year period, 60 medical students provided alcohol education sessions to 1,780 high school pupils (aged 13-15 years) within seven schools in Wales. Strongly positive feedback was obtained from all stakeholders and all schools asked to be included in future programmes. In conclusion, medical student-delivered teaching of alcohol education programmes to school pupils appears to be feasible and welcome by schools, teachers, pupils and medical students.

  13. Caribbean Oceans: Utilizing NASA Earth Observations to Detect, Monitor, and Respond to Unprecedented Levels of Sargassum in the Caribbean Sea

    Ped, Jordan; Scaduto, Erica; Accorsi, Emma; Torres-Perez, Juan (Editor)

    2016-01-01

    In 2011 and 2015, the nations of the Caribbean Sea were overwhelmed by the unprecedented quantity of Sargassum that washed ashore. This issue prompted international discussion to better understand the origins, distribution, and movement of Sargassum, a free-floating brown macro alga with ecological, environmental, and commercial importance. In the open ocean, Sargassum mats serve a vital ecological function. However, when large quantities appear onshore without warning, Sargassum threatens local tourist industries and nearshore ecosystems within the Caribbean. As part of the international response, this project investigated the proliferation of this macro alga within the Caribbean Sea from 2003-2015, and used NASA Earth observations to detect and model Sargassum growth across the region. The Caribbean Oceans team calculated the Floating Algal Index (FAI) using Terra Moderate Resolution Imaging Spectroradiometer (MODIS) data, and compared the FAI to various oceanic variables to determine the ideal pelagic environment for Sargassum growth. The project also examined the annual spread of Sargassum throughout the region by using Earth Trends Modeler (ETM) in Clark Labs' TerrSet software. As part of the international effort to better understand the life cycle of Sargassum in the Caribbean, the results of this project will help local economies promote sustainable management practices in the region.

    2011-11-01

    Medical journals and other sources do not show evidence that cholera occurred in Haiti before 2010, despite the devastating effect of this disease in the Caribbean region in the 19th century. Cholera occurred in Cuba in 1833-1834; in Jamaica, Cuba, Puerto Rico, St. Thomas, St. Lucia, St. Kitts, Nevis, Trinidad, the Bahamas, St. Vincent, Granada, Anguilla, St. John, Tortola, the Turks and Caicos, the Grenadines (Carriacou and Petite Martinique), and possibly Antigua in 1850-1856; and in Guadeloupe, Cuba, St. Thomas, the Dominican Republic, Dominica, Martinique, and Marie Galante in 1865-1872. Conditions associated with slavery and colonial military control were absent in independent Haiti. Clustered populations, regular influx of new persons, and close quarters of barracks living contributed to spread of cholera in other Caribbean locations. We provide historical accounts of the presence and spread of cholera epidemics in Caribbean islands.

  16. Art at the crossroads: Francisco Oller and Caribbean art

    2015-12-01

    Full Text Available Review of Edward J. Sullivan, From San Juan to Paris and Back: Francisco Oller and Caribbean Art in the Era of Impressionism: Francisco Oller (1833-1917 was a Puerto Rican born artist who helped shape the visual production of the Caribbean in the second half of the nineteenth century. He enjoyed a reputation on both sides of the Atlantic, both at home and in Europe, where he spent twenty years. This book fills provides a much-needed analysis of the achievement of Oller, who has received little scholarly attention in the past thirty years. In six chapters that analyze major artworks and themes in Oller’s oeuvre, this book recasts the artist as a key figure in nineteenth century art and sheds new light on his contribution to a uniquely Caribbean aesthetic.

  17. Pupil dilation: a fingerprint of temporal selection during the ‘Attentional Blink’

    Directory of Open Access Journals (Sweden)

    Ariel eZylberberg

    2012-08-01

    Full Text Available Pupil dilation indexes cognitive events of behavioral relevance, like the storage of information to memory and the deployment of attention. Yet, given the slow temporal response of the pupil dilation, it is not known from previous studies whether the pupil can index cognitive events in the short time-scale of ~100 ms. Here we measured the size of the pupil in the Attentional Blink (AB experiment, a classic demonstration of attentional limitations in processing rapidly presented stimuli. In the AB, two targets embedded in a sequence have to be reported and the second stimulus is often missed if presented between 200 ms and 500 ms after the first. We show that pupil dilation can be used as a marker of cognitive processing in AB, revealing both the timing and amount of cognitive processing. Specifically, we found that in the time range where the AB is known to occur: (i the pupil dilation was delayed, mimicking the pattern of response times in the Psychological Refractory Period (PRP paradigm, (ii the amplitude of the pupil was reduced relative to that of larger lags, even for correctly identified targets, and (iii the amplitude of the pupil was smaller for missed than for correctly reported targets. These results support two-stage theories of the Attentional Blink where a second processing stage is delayed inside the interference regime, and indicate that the pupil dilation can be used as a marker of cognitive processing in the time scale of ~100 ms. Furthermore, given the known relation between the pupil dilation and the activity of the locus coeruleus, our results also support theories that link the serial stage to the action of a specific neuromodulator, norepinephrine.

    2007-01-01

    Five dimensional neutral rotating black rings are described from a Randall-Sundrum brane world perspective in the bulk black string framework. To this end we consider a rotating black string extension of a five dimensional black ring into the bulk of a six dimensional Randall-Sundrum brane world with a single four brane. The bulk solution intercepts the four brane in a five dimensional black ring with the usual curvature singularity on the brane. The bulk geodesics restricted to the plane of rotation of the black ring are constructed and their projections on the four brane match with the usual black ring geodesics restricted to the same plane. The asymptotic nature of the bulk geodesics are elucidated with reference to a bulk singularity at the AdS horizon. We further discuss the description of a brane world black ring as a limit of a boosted bulk black 2 brane with periodic identification

    The Caribbean is a region of lush vegetation, beaches, active volcanoes, and significant mountain ranges, all of which create a natural aesthetic that is recognized globally. Yet these very same features, molded through geological, oceanic, and atmospheric processes, also pose natural hazards for the developing countries in the Caribbean. The rise in population density, migration to coastal areas, and substandard building practices, combined with the threat of natural hazards, put the region's human population at risk for particularly devastating disasters. These demographic and social characteristics exist against a backdrop of the threat of an evolving climate, which produces a more vigorous hurricane environment and a rising average sea level.

  2. Textual Transformations in Contemporary Black Writing in Britain

    Directory of Open Access Journals (Sweden)

    Jawhar Ahmed Dhouib

    2014-04-01

    Full Text Available While the first wave of Caribbean immigrant writers brilliantly explored race-related issues, black Britons like Andrea Levy, Zadie Smith and Caryl Phillips, among others, have sought to depart from earlier fiction, motivated in their project by the changing white face of Britain. In this article, I would like to argue that cultural change in Britain has deeply influenced literary production and has, consequently, laid the ground for a series of textual transformations. To capture instances of creative excess in contemporary black writing in Britain, I will bring under examination Caryl Phillips’s (2009 novel In the Falling Snow. My intention is to show to what extent Phillips’s work surpasses the ‘noose of race’ and already-familiar representations of multicultural Britain to celebrate a ‘post-racial’ society.

    In this article, we review recent research on mental health in the Caribbean. Three major themes emerge: (a) the effects of colonialism on the Caribbean psyche; (b) decolonization of psychiatric public policy, including innovative treatment approaches, deinstitutionalization, and community and policy responses to mental health issues; and (c) the nature and epidemiology of psychiatric pathology among contemporary Caribbean people, with particular focus on migration, genetic versus social causation of psychosis and personality disorders, and mechanisms of resilience and social capital. Caribbean transcultural psychiatry illustrates the principles of equipoise unique to developing countries that protect the wellness and continued survival of postcolonial Caribbean people.

  6. Microarcsecond relative astrometry from the ground with a diffractive pupil

    Energy Technology Data Exchange (ETDEWEB)

    Ammons, S M; Bendek, E; Guyon, O

    2011-09-08

    The practical use of astrometry to detect exoplanets via the reflex motion of the parent star depends critically on the elimination of systematic floors in imaging systems. In the diffractive pupil technique proposed for space-based detection of exo-earths, extended diffraction spikes generated by a dotted primary mirror are referenced against a wide-field grid of background stars to calibrate changing optical distortion and achieve microarcsecond astrometric precision on bright targets (Guyon et al. 2010). We describe applications of this concept to ground-based uncrowded astrometry using a diffractive, monopupil telescope and a wide-field camera to image as many as {approx}4000 background reference stars. Final relative astrometric precision is limited by differential tip/tilt jitter caused by high altitude layers of turbulence. A diffractive 3-meter telescope is capable of reaching {approx}35 {micro}as relative astrometric error per coordinate perpendicular to the zenith vector in three hours on a bright target star (I < 10) in fields of moderate stellar density ({approx}40 stars arcmin{sup -2} with I < 23). Smaller diffractive apertures (D < 1 m) can achieve 100-200 {micro}as performance with the same stellar density and exposure time and a large telescope (6.5-10 m) could achieve as low as 10 {micro}as, nearly an order of magnitude better than current space-based facilities. The diffractive pupil enables the use of larger fields of view through calibration of changing optical distortion as well as brighter target stars (V < 6) by preventing star saturation. Permitting the sky to naturally roll to average signals over many thousands of pixels can mitigate the effects of detector imperfections.

    Full Text Available Background:: Most studies on mental health associates of obesity have focused on depression and less is known about the role of anxiety in obesity.. Objectives:: This study compared the additive effects of General Anxiety Disorder (GAD and Major Depressive Disorder (MDD on Body Mass Index (BMI across sub-populations of Blacks based on the intersection of ethnicity and gender.. Methods:: Data came from the National Survey of American Life (NSAL, 2001 - 2003. The participants consisted of 3,570 African Americans and 1,621 Caribbean Blacks. Twelve-month MDD and GAD were determined using the World Mental Health Composite International Diagnostic Interview (CIDI. Levels of BMI were categorized based on being equal to or larger than 25, 30, 35, and 40 kg/m2. We fitted linear regression models specific for our groups, which were defined based on the intersection of ethnicity and gender. Additionally, age, education, marital status, employment, and region were controlled.. Results:: Among Caribbean Black men and African American women, lifetime GAD, but not MDD, was associated with high BMI. Among Caribbean Black women, lifetime MDD, but not GAD, was associated with high BMI.. Conclusions:: Intersection of ethnicity and gender may determine how anxiety and depression are associated with BMI among Blacks. Sub-populations of Blacks (e.g. based on ethnicity and gender may have specific mental health determinants or consequences of obesity. Future research should investigate how and why the additive effects of anxiety and depression on obesity vary across ethnic and gender groups of Blacks..

Twelve-month MDD and GAD were determined using the World Mental Health Composite International Diagnostic Interview (CIDI). Levels of BMI were categorized based on being equal to or larger than 25, 30, 35, and 40 kg/m2. We fitted linear regression models specific for our groups, which were defined based on the intersection of ethnicity and gender. Additionally, age, education, marital status, employment, and region were controlled. Results: Among Caribbean Black men and African American women, lifetime GAD, but not MDD, was associated with high BMI. Among Caribbean Black women, lifetime MDD, but not GAD, was associated with high BMI. Conclusions: Intersection of ethnicity and gender may determine how anxiety and depression are associated with BMI among Blacks. Sub-populations of Blacks (e.g. based on ethnicity and gender) may have specific mental health determinants or consequences of obesity. Future research should investigate how and why the additive effects of anxiety and depression on obesity vary across ethnic and gender groups of Blacks. PMID:24936480

    We conducted five pupil old/new experiments to examine whether pupil old/new effects can be linked to familiarity and/or recollection processes of recognition memory. In Experiments 1-3, we elicited robust pupil old/new effects for legal words and pseudowords (Experiment 1), positive and negative words (Experiment 2), and low-frequency and high-frequency words (Experiment 3). Importantly, unlike for old/new effects in ERPs, we failed to find any effects of long-term memory representations on pupil old/new effects. In Experiment 4, using the words and pseudowords from Experiment 1, participants made lexical decisions instead of old/new decisions. Pupil old/new effects were restricted to legal words. Additionally requiring participants to make speeded responses (Experiment 5) led to a complete absence of old/new effects. Taken together, these data suggest that pupil old/new effects do not map onto familiarity and recollection processes of recognition memory. They rather seem to reflect strength of memory traces in short-term memory, with little influence of long-term memory representations. Crucially, weakening the memory trace through manipulations in the experimental task significantly reduces pupil/old new effects. © 2016 Society for Psychophysiological Research.

    To explore the association between types of unintentional injuries and influential factors among rural rear pupils. The multistage stratified sampling method was used to select the study participant and thus 594 rural pupils were sampled, 292 rear pupils were confirmed and measured with unintentional injuries and influential factors of rural rear pupils scale. Binary logistic regression analysis indicate that the risk facts related to unintentional injury were left-behind status (OR = 2.68, 95% CI 1.06-6.79), gender (OR = 5.12, 95% C2.68-9.79) and surrounding environment (OR = 3.44, 95% CI 1.37-8.70). Correspondence analysis showed living with father, middle personality and low age were related possibly with traffic accident injury. Living with grandparents, extrovert personality and elder pupils were related possibly with unintentional falls injury. Living with mother, introvert personality and middle-age pupils were related possibly with animmal injury. The personality, ages and guardian types of rural rear pupils are correlated with types of unintentional injuries.

    Macroscopic entropy of an extremal black hole is expected to be determined completely by its near horizon geometry. Thus two black holes with identical near horizon geometries should have identical macroscopic entropy, and the expected equality between macroscopic and microscopic entropies will then imply that they have identical degeneracies of microstates. An apparent counterexample is provided by the 4D-5D lift relating BMPV black hole to a four dimensional black hole. The two black holes have identical near horizon geometries but different microscopic spectrum. We suggest that this discrepancy can be accounted for by black hole hair - degrees of freedom living outside the horizon and contributing to the degeneracies. We identify these degrees of freedom for both the four and the five dimensional black holes and show that after their contributions are removed from the microscopic degeneracies of the respective systems, the result for the four and five dimensional black holes match exactly.

  14. School Xenophobia and Interethnic Relationships Among Secondary Level Pupils in Spain

    Full Text Available Migratory processes in southern Europe over the last two decades have brought about substantial changes to the ethnic makeup of secondary schools. Classrooms have increased in their complexity in terms of teaching, as there are pupils with different cultural and economic backgrounds and educational needs, but also in the relationships among the peer groups of pupils. What kinds of attitudes and relations can be found among the members of this culturally diverse pupil body? What kinds of views are held by the pupils about each other? The aim of this paper is to shed light on stereotypes and xenophobic attitudes towards immigrant pupils in secondary schools in Spain, principally among peer groups, and on how teachers address this multicultural classroom dynamic and complexity and any possible prejudices towards stereotypes and racist attitudes that surface inside the classroom. Relationships tend to be formed among peer groups of the same ethnicity and there is a marked rejection of pupils from Moroccan origin. Teachers are neither aware of pupils’ stereotypes nor of their own. As a consequence, they are not giving sufficient pedagogical responses to resolve arguments or disrespectful situations against immigrant pupils. This in turn is contributing, on the one hand, to racist and xenophobic societies (Banks 2011; Deusdad 2013. On the other hand, teachers’ low expectations of these immigrant pupils has had an effect on their academic achievements and on dropout rates (Deusdad 2009. The present study is based on 2196 questionnaires administered to pupils at 43 Spanish secondary schools. In-depth interviews with 54 secondary school teachers were also carried out, so as to understand teachers’ discourses and pedagogical resources.

    This is a review of current theory of black-hole dynamics, concentrating on the framework in terms of trapping horizons. Summaries are given of the history, the classical theory of black holes, the defining ideas of dynamical black holes, the basic laws, conservation laws for energy and angular momentum, other physical quantities and the limit of local equilibrium. Some new material concerns how processes such as black-hole evaporation and coalescence might be described by a single trapping h...

    Recent work, which has been investigating the use of the concept of entropy with respect to gravitating systems, black holes and the universe as a whole, is discussed. The resulting theory of black holes assigns a finite temperature to them -about 10 -7 K for ordinary black holes of stellar mass -which is in complete agreement with thermodynamical concepts. It is also shown that black holes must continuously emit particles just like ordinary bodies which have a certain temperature. (U.K.)
