    Full Text Available The present study explores two hypotheses: a women during early pregnancy should experience increased color discrimination ability, and b women during early pregnancy should experience shifts in subjective preference away from images of foods that appear either unripe or spoiled. Both of these hypotheses derive from an adaptive view of pregnancy sickness that proposes the function of pregnancy sickness is to decrease the likelihood of ingestion of foods with toxins or teratogens. Changes to color discrimination could be part of a network of perceptual and physiological defenses (e.g., changes to olfaction, nausea, vomiting that support such a function. Participants included 13 pregnant women and 18 non-pregnant women. Pregnant women scored significantly higher than non-pregnant controls on the Farnsworth-Munsell (FM 100 Hue Test, an objective test of color discrimination, although no difference was found between groups in preferences for food images at different stages of ripeness or spoilage. These results are the first indication that changes to color discrimination may occur during early pregnancy, and is consistent with the view that pregnancy sickness may function as an adaptive defense mechanism.

    Over recent years, the terms race and ethnicity have been used to ascertain inequities in public health. However, this use depends on the quality of the data available. This study aimed to investigate the description of color/race in Brazilian scientific journals within the field of biomedicine. Descriptive study with systematic search for scientific articles in the SciELO Brazil database. A wide-ranging systematic search for original articles involving humans, published in 32 Brazilian biomedical scientific journals in the SciELO Brazil database between January and December 2008, was performed. Articles in which the race/ethnicity of the participants was identified were analyzed. In total, 1,180 articles were analyzed. The terms for describing race or ethnicity were often ambiguous and vague. Descriptions of race or ethnicity occurred in 159 articles (13.4%), but only in 42 (26.4%) was there a description of how individuals were identified. In these, race and ethnicity were used almost interchangeably and definition was according to skin color (71.4%), ancestry (19.0%) and self-definition (9.6%). Twenty-two races or ethnicities were cited, and the most common were white (37.3%), black (19.7%), mixed (12.9%), nonwhite (8.1%) and yellow (8.1%). The absence of descriptions of parameters for defining race, as well as the use of vague and ambiguous terms, may hamper and even prevent comparisons between human groups and the use of these data to ascertain inequities in healthcare.

    Full Text Available Abstract Objectives: to investigate the epidemiological profile, by race/skin color, of maternal deaths in the state of Mato Grosso do Sul, Brazil. Methods: the present epidemiological study of maternal death distribution by race/skin color was based on data extracted from Brazilian mortality and livebirth information systems from 2010 to 2015. The maternal mortality ratio and the specific maternal mortality ratio were calculated and analyzed according to obstetric variables. Results: the death risk for black (RR = 4.3, CI95%= 2.088.71 and indigenous women (RR = 3.7, CI95% 2.26.23 was approximately fourfold in comparison to the risk for white women. For direct causes of death, the state of Mato Grosso do Sul showed higher levels, 74.1%, as well as for most races/skin colors in the first triennium. The specific maternal mortality ratio was higher among black and indigenous women aged30 to 39 years old (416.7 and 651.8, respectively per 100,000 live births (p<0.05. Conclusions: higher maternal mortality ratio for indigenous and black women and the predominance of deaths related to direct obstetric causes among race/skin color categories reflect inadequate health care during pregnancy and puerperium.

    2017-01-01

    Color-blind racial ideology has historically been conceptualized as an ideology wherein race is immaterial. Efforts not to "see" race insinuate that recognizing race is problematic; therefore, scholars have identified and critiqued color-blindness ideology. In this paper, we first examine Gotanda's (1991) identification and critique of…

    Color blind discourse often draws on sentiments such as, "When I look at you, I do not see color," or race should not matter since we are all human, we are all the same underneath. In other words, the desire to view others as individuals is often constituted on the back of the desire to understand the notion of the individual as one who…

    2017-08-01

    The skin color/race and urbanity are structural determinants of health. The relationship between these variables produces structure of social stratification that defines inequalities in the experiences of life and death. Thus, this study describes the characteristics of the mortality indicators by skin color/race according level of urbanity and aggregation to the metropolitan region (MR) of 5565 cities in Brazil, controlling for gender and age. Descriptive study which included the calculation of measures relating to 1,050,546 deaths in the year survey of 2010 by skin color/race White, Black, and Brown according to both sexes, for five age groups and three levels of urbanity of cities in Brazil that were aggregated or not to the MR in the year of study. The risk of death was estimated by calculating premature mortality rate (PMR) at 65 years of age, per 100,000 and age adjusted. The structure of mortality by skin color/race Black and Brown reflects worse levels of health and excessive premature deaths, with worse situation for men. The Whites, especially women, tend to live longer and in better health than other racial groups. The age-adjusted PMR indicates distinct risk of death by skin color/race, this risk was higher in men than in women and in Blacks than in other racial groups of both sexes. There have been precarious levels of health in the urban space and the MR has intensified these inequalities. The research pointed out that the racial inequality in the mortality was characterized by interaction of race with other individual and contextual determinants of health. Those Blacks and Browns are the groups most vulnerable to the iniquities associated with occurrence of death, but these differences in the profile and the risk of death depend on the level of urbanity and aggregation MR of Brazilian cities in 2010.

  19. Comparison between two race/skin color classifications in relation to health-related outcomes in Brazil

    Directory of Open Access Journals (Sweden)

    Szwarcwald Celia L

    2011-08-01

    Full Text Available Abstract Background This paper aims to compare the classification of race/skin color based on the discrete categories used by the Demographic Census of the Brazilian Institute of Geography and Statistics (IBGE and a skin color scale with values ranging from 1 (lighter skin to 10 (darker skin, examining whether choosing one alternative or the other can influence measures of self-evaluation of health status, health care service utilization and discrimination in the health services. Methods This is a cross-sectional study based on data from the World Health Survey carried out in Brazil in 2003 with a sample of 5000 individuals older than 18 years. Similarities between the two classifications were evaluated by means of correspondence analysis. The effect of the two classifications on health outcomes was tested through logistic regression models for each sex, using age, educational level and ownership of consumer goods as covariables. Results Both measures of race/skin color represent the same race/skin color construct. The results show a tendency among Brazilians to classify their skin color in shades closer to the center of the color gradient. Women tend to classify their race/skin color as a little lighter than men in the skin color scale, an effect not observed when IBGE categories are used. With regard to health and health care utilization, race/skin color was not relevant in explaining any of them, regardless of the race/skin color classification. Lack of money and social class were the most prevalent reasons for discrimination in healthcare reported in the survey, suggesting that in Brazil the discussion about discrimination in the health care must not be restricted to racial discrimination and should also consider class-based discrimination. The study shows that the differences of the two classifications of race/skin color are small. However, the interval scale measure appeared to increase the freedom of choice of the respondent.

    2014-04-01

    To investigate the association between maternal pre-pregnancy obesity, race/ethnicity and prematurity. Retrospective cohort study of maternal deliveries at a single regional center from 2009 to 2010 time period (n = 11,711). Generalized linear models were used for the analysis to estimate an adjusted odds ratio with 95% confidence interval of the association between maternal pre-pregnancy obesity, race/ethnicity and prematurity. Analysis controlled for diabetes, chronic hypertension, previous preterm birth, smoking and insurance status. The demographics of the study population were as follows, race/ethnicity had predominance in the White/Non-Hispanic population with 60.1%, followed by the Black/Non-Hispanic population 24.2%, the Hispanic population with 10.3% and the Asian population with 5.4%. Maternal pre-pregnancy weight showed that the population with a normal body mass index (BMI) was 49.4%, followed by the population being overweight with 26.2%, and last, the population which was obese with 24.4%. Maternal obesity increased the odds of prematurity in the White/Non-Hispanic, Hispanic and Asian population (aOR 1.40, CI 1.12-1.75; aOR 2.20, CI 1.23-3.95; aOR 3.07, CI 1.16-8.13, respectively). Although the Black/Non-Hispanic population prematurity rate remains higher than the other race/ethnicity populations, the Black/Non-Hispanic population did not have an increased odds of prematurity in obese mothers (OR 0.87; CI 0.68-1.19). Unlike White/Non-Hispanic, Asian and Hispanic mothers, normal pre-pregnancy BMI in Black/Non-Hispanic mothers was not associated with lower odds for prematurity. The odds for mothers of the White/Non-Hispanic, Hispanic and Asian populations, for delivering a premature infant, were significantly increased when obese. Analysis controlled for chronic hypertension, diabetes, insurance status, prior preterm birth and smoking. Obesity is a risk factor for prematurity in the White/Non-Hispanic, Asian and Hispanic population, but not for the

    To analyze the association between race/skin color and the occurrence of prematurity. Meta-analysis with observational studies, selected by a systematic review in the bibliographic databases Medline and Biblioteca Virtual da Saúde with the descriptors: "Race or ethnic group" and "ethnicity and health" associated with the words "infant premature" and "obstetric labor premature". Articles published in the period from 2010 to 2014, of the observational epidemiological type, in Portuguese, English and Spanish, were included. Articles that did not have abstracts or that were review articles, theses, dissertations, and editorials were excluded. We adopted the relative risk and their respective confidence intervals (95%CI) as measures of effect, obtained through the random effect model and represented by the forest plot type graph. The Egger test and the Newcastle-Ottawa scale, respectively, were used to analyze possible publication biases and the quality of the studies. Of the 926 articles identified, 17 were eligible for the study. Of the 17 full texts published, seven were retrospective cohort studies, nine were cross-sectional studies, and one was a case-control study. Except for one study, the others reported a positive association between race/color of skin and prematurity. Compared with full-term newborns, the relative risk of the combined effect in those born preterm was 1.51 (95%CI 1.39-1.69). The funnel chart suggested publication bias. The present meta-analysis indicated a positive association for the risk of prematurity according to race/skin color.

    2012-01-01

    This article explores race relations and racism within the lesbian, gay, bisexual, transgender, and queer (LGBTQ) community of Toronto, Ontario, from the perspective of seven gay/queer social service providers of color. Social constructions of race, race relations, and racism were placed at the centre of analysis. Employing interpretive phenomenological analysis, findings indicated that intergroup and broader systemic racism infiltrates the LGBTQ community, rendering invisible the lived experiences of many LGBTQ people of color. The study contributes to a growing body of research concerning our understanding of factors underpinning social discrimination in a contemporary Canadian LGBTQ context.

    More women are entering pregnancy with pre-existing diabetes. Disease severity, glycaemic control, and predictors of pregnancy complications may differ by race/ethnicity or educational attainment, leading to differences in adverse pregnancy outcomes. We used linked New York City hospital record and birth certificate data for 6291 singleton births among women with pre-existing diabetes between 1995 and 2003. We defined maternal race/ethnicity as non-Hispanic white, non-Hispanic black, Hispanic, South Asian, and East Asian, and education level as 12 years. Our outcomes were pre-eclampsia, preterm birth (PTB) (pregnancy complications. Non-Hispanic black, Hispanic, and South Asian women with pre-existing diabetes may benefit from targeted interventions to improve pregnancy outcomes. © 2013 The Authors.

    2017-04-10

    To analyze the quality of records for live births and infant deaths and to estimate the infant mortality rate for skin color or race, in order to explore possible racial inequalities in health. Descriptive study that analyzed the quality of records of the Live Births Information System and Mortality Information System in Rondônia, Brazilian Amazonian, between 2006-2009. The infant mortality rates were estimated for skin color or race with the direct method and corrected by: (1) proportional distribution of deaths with missing data related to skin color or race; and (2) application of correction factors. We also calculated proportional mortality by causes and age groups. The capture of live births and deaths improved in relation to 2006-2007, which required lower correction factors to estimate infant mortality rate. The risk of death of indigenous infant (31.3/1,000 live births) was higher than that noted for the other skin color or race groups, exceeding by 60% the infant mortality rate in Rondônia (19.9/1,000 live births). Black children had the highest neonatal infant mortality rate, while the indigenous had the highest post-neonatal infant mortality rate. Among the indigenous deaths, 15.2% were due to ill-defined causes, while the other groups did not exceed 5.4%. The proportional infant mortality due to infectious and parasitic diseases was higher among indigenous children (12.1%), while among black children it occurred due to external causes (8.7%). Expressive inequalities in infant mortality were noted between skin color or race categories, more unfavorable for indigenous infants. Correction factors proposed in the literature lack to consider differences in underreporting of deaths for skin color or race. The specific correction among the color or race categories would likely result in exacerbation of the observed inequalities.

    Depression before and during pregnancy is associated with adverse birth outcomes including low birth weight and preterm birth. Abnormal maternal cortisol has been hypothesized as one mediator between depression and adverse birth outcomes. The relationship between cortisol and depression in pregnancy is exhibited most strongly in the African American population, and most studies have focused either on circulating or placental levels of cortisol. The utility of urinary cortisol in early pregnancy related to depression and adiposity has not been investigated. Twenty-five pregnant African American women identified by the Edinburgh Depression Scale as having depression were investigated and matched by body mass index (BMI), age, race, and infant birth weight centile to non-depressed subjects. Maternal urine and plasma cortisol in early pregnancy were quantified and investigated in relation to depression and adiposity. Morning urine cortisol levels tracked positively with plasma cortisol (r(2) = 0.25, p cortisol between depressed and non-depressed pregnant women. Plasma cortisol was significantly negatively associated with several measures of maternal adiposity including percent body fat (r(2) = -0.10, p obese women were found to have significantly higher cortisol levels compared to women with depression, obesity or both (p obese pregnant women evidence atypical cortisol levels compared to non-depressed non-obese pregnant women. Plasma cortisol in early pregnancy is negatively associated with measures of maternal adiposity. Atypical low circulating maternal cortisol among depressed (lean and obese) and non-depressed obese pregnant African American women may indicate hypothalamic-pituitary axis dysfunction in early pregnancy.

    2015-11-01

    Full Text Available Here are presented the results of a research whose objective was to analyze what were saying and how were acting poor and/or black boy(s and girl(s about unequal treatment, shaped by discrimination through mockery, swearing, derogatory nicknames, separations, among other things, experienced in school. These children were students from the 5th year of primary school, in a public school located in a mid-sized city in the interior of São Paulo, Brazil. It was intended to undertake an analysis of the practices of class and racial differentiation that hierarchize, discriminate and exclude certain children, performed by adults and/or by children themselves. The ethnographic study made use of their stories, a questionnaire about denomination and classification of color/race, answered by children in the classroom, socio-economic survey, observations of children in different school environments and semi-structured interview with children and teacher. Among other results, it was confirmed that, children that were black, black and brown, poor and with a history of educational failure, suffer bigger discrimination at school from teachers and other children. In addition it was found that even among those who are poor and or black, it takes place the building of borders for the distinction that each one makes of themselves in relation to others. Therefore, the research provided the acknowledgement of the diversity of positions related to the recognition that they make regarding their identification of race and class. When verifying how children's actions are mediated by school educational practices, we support that in such spaces it should be granted the conditions of possibilities for them to speak - and be heard - about their doubts and desires, about what they do and why they do it, in the relations between them. Finally, provide the emergence of their curiosities, imagination and inventiveness to, maybe, see the burst of something new in our world that

    1999-01-01

    To assess uterine contractions in early pregnancies using transvaginal color Doppler sonography (TVCDS) and to determine the role of uterine contractions in the diagnosis of early pregnancy failure. 76 patients with abnormal pregnancy diagnosed by sonography or histopathology up to 10 weeks of gestation and 38 normal pregnant women as the control group were examines with TVCDS. The presence of uterine contractions was determined by complete or partial disappearance of the color flow signals of vessels within myometrium, and the direction, amplitude (grade 1-3), and interval of uterine contractions were also evaluated. Uterine contractions were identified in 42 (55.3%) of 76 patients with abnormal pregnancy, whereas they were detected only in 2 (5.3%) of 38 normal pregnant women who had initial grade 1 contraction but disappeared in the follow-up study.

    To assess uterine contractions in early pregnancies using transvaginal color Doppler sonography (TVCDS) and to determine the role of uterine contractions in the diagnosis of early pregnancy failure. 76 patients with abnormal pregnancy diagnosed by sonography or histopathology up to 10 weeks of gestation and 38 normal pregnant women as the control group were examines with TVCDS. The presence of uterine contractions was determined by complete or partial disappearance of the color flow signals of vessels within myometrium, and the direction, amplitude (grade 1-3), and interval of uterine contractions were also evaluated. Uterine contractions were identified in 42 (55.3%) of 76 patients with abnormal pregnancy, whereas they were detected only in 2 (5.3%) of 38 normal pregnant women who had initial grade 1 contraction but disappeared in the follow-up study. In 26 patients with blighted ovum or missed abortion, 15 patients (57.7%),showed uterine contraction of grade 1 in 3 cases, grade 2 in 8 cases, and grade 3 in 4 cases and interval from 45 seconds to 5 minutes. In 30 patients with inevitable or incomplete abortion, 23 patients (76.6%) showed uterine contraction of grade 1 in 2 cases, grade 2 in 9 cases, and grade 3 in 12 cases and interval from 1 to 5 minutes. 4 (20%) of 20 patients with threatened abortion had uterine contraction of grade 2 and interval from 2 to 4 minutes.

    Increasing trainees' multicultural counseling competence (MCC) has been a hot topic in counseling. Scholars have identified predictors (e.g., race/ethnicity, color-blindness) of MCC, and educators provide multicultural training for trainees. Using a sample of 370 psychology trainees, this study examined whether multicultural training (a) moderated racial/ethnic differences on MCC and (b) changed the relationship between color-blindness and MCC. Results indicated a significant interaction effect of race/ethnicity (i.e., White vs. ethnic minority) and multicultural training on multicultural awareness, but not on multicultural knowledge. Specifically, at lower levels of training, racial/ethnic minority trainees had significantly higher multicultural awareness than their White counterparts; at higher levels of training, no significant difference was found. Described differently, more training significantly enhanced Whites' multicultural awareness, but did not enhance racial/ethnic minority trainees' awareness. Additionally, there was a significant interaction effect of color-blindness and multicultural training on multicultural knowledge, but not on multicultural awareness. The association between color-blindness and multicultural knowledge was stronger at higher levels of multicultural training than at lower levels of training. Alternatively, the effect of training on enhancing knowledge was stronger for those with lower color-blindness than for those with higher color-blindness.

    Objective: Detecting and assessment the corpus luteum blood flow in normal and abnormal early pregnancy. Methods: Using transvaginal color and pulse Doppler sonography, we detected 215 pregnant women including 150 normal intrauterine pregnancies, 25 abortion, 29 ectopic pregnancies, and then recorded corpus luteum blood flow feature and the blood flow indexes (Vmax, RI and PI). Results: 1) Corpus luteum was successfully identified in 148 cases out of 150 of normal early pregnancies, 25 cases out of 26 of threatened abortion; 22 cases out of 29 of ectopic pregnancy. 2) Three groups shared the same feature of Color Doppler imaging: a circumferential rim around the entire corpus luteum. 3) The flow index revealed mean PVS, RI and PI had no statistical difference in normal and abnormal early pregnancy; The mean PVS was lower in ectopic pregnancy than in normal pregnancy (P<0.05), while PI and PR had no characteristic in ectopic pregnancy group compared with the indexes obtained in normal pregnancy group. Conclusion: The corpus luteum can be precisely identified in most pregnancy using transvaginal color Doppler and manifests a characterized rim Doppler imaging. PVS may help in differentiating the ectopic pregnancy from normal early pregnancy. (authors)

    Colour signals arise in a variety of sexual contexts, including advertising reproductive status. Despite potentially attracting negative attention from unrelated competitors, bright pregnancy coloration may communicate gestation to kin and potential fathers, thereby garnering aid during agonistic encounters and reducing the overall amount of aggression received by pregnant females. To establish whether this 'pregnancy sign' influences rates of aggression in the presence versus absence of maternal kin, we conducted behavioural observations of wild olive baboons, Papio anubis , in Gombe National Park, Tanzania, in groups composed of maternal kin and nonkin, and of captive baboons at the Southwest National Primate Research Center (SNPRC, San Antonio, TX, U.S.A.), in group enclosures that were unlikely to include close kin. At SNPRC, we also experimentally obscured the coloration of the pregnancy sign, and we performed playback experiments to measure male responses to the distress calls of pregnant females. Free-ranging female baboons experienced significantly less aggression from nonkin females after the onset of the pregnancy sign compared to the pre-pregnancy sign. In contrast, captive pregnant females whose pregnancy coloration was obscured with paint experienced significantly lower aggression rates from female conspecifics compared to pre-painting. Male aggression towards females did not differ in the presence versus absence of the pregnancy sign in either the wild or the captive population, although captive fathers paid significantly more attention to distress calls of pregnant cage-mates than they did to those of cycling cage-mates, suggesting a willingness to aid mothers that were carrying their unborn offspring.

    Horses have substantial variation in coat color, and the genetic loci responsible for the coat color variations have been well investigated. It has been believed that some color variations should follow a single-locus Mendelian law. Examples include the Gray locus that causes the gray phenotype and the Extension locus that specifies the chestnut phenotype. We reevaluated the roles of the Gray and Extension loci by using a large number of mating records of Thoroughbred racing horses. We showed that the data indeed fits the Mendelian law extremely well for the two loci. Furthermore, we demonstrated that the Extension and Agouti loci might have an additional role in determining the degree of melanin that should distinguish bay, dark bay, and brown.

    Brain-derived neurotrophic factor (BDNF) is implicated as a causal factor in major depression and is critical to placental development during pregnancy. Longitudinal data on BDNF across the perinatal period are lacking. These data are of interest given the potential implications for maternal mood and fetal growth, particularly among Black women who show ∼2-fold greater risk for delivering low birth weight infants. Serum BDNF, serum cortisol, and depressive symptoms (per CES-D) were assessed during each trimester and 4-11 weeks postpartum among 139 women (77 Black, 62 White). Low birth weight (BDNF declined considerably from 1st through 3rd trimesters (ps≤0.008) and subsequently increased at postpartum (pBDNF during the 1st trimester, 2nd trimester, and postpartum (ps≤0.032) as well as lower serum cortisol during the 2nd and 3rd trimester (ps≤0.01). Higher serum cortisol was concurrently associated with lower serum BDNF in the 2nd trimester only (pBDNF at both the 2nd and 3rd trimester was negatively associated with 3rd trimester depressive symptoms (ps≤0.02). In addition, women delivering low versus healthy weight infants showed significantly lower serum BDNF in the 3rd trimester (p=0.004). Women delivering low versus healthy weight infants did not differ in depressive symptoms at any time point during pregnancy (ps≥0.34). Serum BDNF declines considerably across pregnancy in Black and White women, with overall higher levels in Blacks. Lower serum BDNF in late pregnancy corresponds with higher depressive symptoms and risk for low birth weight in Black and White women. However, the predictive value of serum BDNF in pregnancy is specific to within-race comparisons. Potential links between racial differences in serum BDNF and differential pregnancy-related cortisol adaptation require further investigation. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Objective: To study the operation of chorionic villus sampling (CVS) guided by color Doppler ultrasound (CDU) via abdomen puncture during early pregnancy and investigate the advertences during the operation. Methods: CVS guided by CDU probe via abdomen puncture were operated on 28 pregnant women who had the indications of antenatal diagnosis. CDU was used to observe the implantation position of the fo1iaceous villis and help setting mark of the puncture point and puncture range on body surface before operation. The needle was punctured under real-time ultrasound guidance and villis were aspirated during the operation: The choice of the right time of puncture and the operation skills were emphasized in the study. Results: The CVS puncture approach should be set through CDU ob servation, which attend to avoid the surrounding blood vessels, intestinal canal and surrounding important organs. The puncture point should be chosen in a point where lobif0rmed villis distributed wider and with a larger scope. The operations were performed from 10 to13 weeks of pregnancy, with an average of 11 weeks. Among these 28 cases, 9.6 were successfully drawn materials in one time, 1 in twice and l failure, with the total ratio of achievement was 96.4%. For all the cases, fetal heart pulsating could be seen by real-time CDU observation fight after the operation, and no larger hematoma echo in the placental site occurred. Ultrasound reexamined one week after the operation, fetal heart pulsation could be found in all cases, and no abortion cases occurred after regular follow-up in 25 continued pregnant patients. Conclusion: Abdominal CVS puncture guided by CDU probe is conveniently operated, safe and available in clinic. It is an important method for antenatal diagnosis during early pregnancy. The puncture localization, skills and the time are the key points for the success in obtaining the materials. (authors)

    This study aims to evaluate vaginal microbiota differences by bacterial vaginosis (BV), birth timing, and race, and to estimate parameters to power future vaginal microbiome studies. Previously, vaginal swabs were collected at 21 to 25 weeks (stored at -80°C), and vaginal smears evaluated for BV (Nugent criteria). In a blinded fashion, 40 samples were selected, creating 8 equal-sized groups stratified by race (black/white), BV (present/absent), and birth timing (preterm/term). Samples were thawed, DNA extracted, and prepared. Polymerase chain reaction (PCR) with primers targeting the 16S rDNA V4 region was used to prepare an amplicon library. PCR products were sequenced and analyzed using quantitative insight into microbial ecology; taxonomy was assigned using ribosomal database program classifier (threshold 0.8) against the modified Greengenes database. After quality control, 97,720 sequences (mean) per sample, single-end 250 base-reads, were analyzed. BV samples had greater microbiota diversity (p Microbiota did not differ by race or birth timing, but there was an association between certain microbial clusters and preterm birth (p = 0.07). To evaluate this difference, 159 patients per group are needed. There are differences in the vaginal microbiota between patients with and without BV. Larger studies should assess the relationship between microbiota composition and preterm birth. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

    Humans in all societies form and participate in cooperative alliances. To successfully navigate an alliance-laced world, the human mind needs to detect new coalitions and alliances as they emerge, and predict which of many potential alliance categories are currently organizing an interaction. We propose that evolution has equipped the mind with cognitive machinery that is specialized for performing these functions: an alliance detection system. In this view, racial categories do not exist because skin color is perceptually salient; they are constructed and regulated by the alliance system in environments where race predicts social alliances and divisions. Early tests using adversarial alliances showed that the mind spontaneously detects which individuals are cooperating against a common enemy, implicitly assigning people to rival alliance categories based on patterns of cooperation and competition. But is social antagonism necessary to trigger the categorization of people by alliance—that is, do we cognitively link A and B into an alliance category only because they are jointly in conflict with C and D? We report new studies demonstrating that peaceful cooperation can trigger the detection of new coalitional alliances and make race fade in relevance. Alliances did not need to be marked by team colors or other perceptually salient cues. When race did not predict the ongoing alliance structure, behavioral cues about cooperative activities up-regulated categorization by coalition and down-regulated categorization by race, sometimes eliminating it. Alliance cues that sensitively regulated categorization by coalition and race had no effect on categorization by sex, eliminating many alternative explanations for the results. The results support the hypothesis that categorizing people by their race is a reversible product of a cognitive system specialized for detecting alliance categories and regulating their use. Common enemies are not necessary to erase important

    To analyze the relationship between gender, race/ethnicity, and the probability of being awarded an R01 grant from the National Institutes of Health (NIH). The authors used data from the NIH Information for Management, Planning, Analysis, and Coordination grants management database for the years 2000-2006 to examine gender differences and race/ethnicity-specific gender differences in the probability of receiving an R01 Type 1 award. The authors used descriptive statistics and probit models to determine the relationship between gender, race/ethnicity, degree, investigator experience, and R01 award probability, controlling for a large set of observable characteristics. White women PhDs and MDs were as likely as white men to receive an R01 award. Compared with white women, Asian and black women PhDs and black women MDs were significantly less likely to receive funding. Women submitted fewer grant applications, and blacks and women who were new investigators were more likely to submit only one application between 2000 and 2006. Differences by race/ethnicity explain the NIH funding gap for women of color, as white women have a slight advantage over men in receiving Type 1 awards. Findings of a lower submission rate for women and an increased likelihood that they will submit only one proposal are consistent with research showing that women avoid competition. Policies designed to address the racial and ethnic diversity of the biomedical workforce have the potential to improve funding outcomes for women of color.

  14. Women, race, and science: The academic experiences of twenty women of color with a passion for science

    Science.gov (United States)

    Johnson, Angela C.

    Women of color drop out of science at higher rates than other students. This study is an ethnographic examination of why this occurs and how women of color can be supported in studying science. Through participant observation in science classes, labs, and a program supporting high-achieving students of color, as well as interviews with minority women science students, the student identities celebrated by science departments, as well as those embraced by my informants, were uncovered. Cultural norms of science classes often differed from those of the women in the study. Only one identity---apprentice research scientist---was celebrated in science settings, although others were tolerated. The women tended to either embrace the apprentice research scientist identity, form an alternative science-oriented identity, or never form a satisfying science student identity. Women who were more racially marked were more likely to fall into the second and third groups. This study uncovered difficulties which women students of color faced more than other science students. In addition, it uncovered several seemingly neutral institutional features of science lectures and labs which actually served to discourage or marginalize women students of color. It revealed values held in common by the women in the study and how those characteristics (especially altruism and pride and pleasure in academic challenge) led them to study science. It also revealed strategies used by the most successful women science students, as well as by professors and programs most successful at supporting women of color in the study of science. Based on this study, increasing the participation of women of color in science holds the possibility of altering the basic values of science; however, institutional features and personal interactions within science departments tend to resist those changes, primarily by encouraging women of color to abandon their study of science.

  15. MARGINALIZATION OF SOUTH ASIANS BASED ON THE RACE AND SKIN COLOR IN BHARATI MUKHERJEE’S "JASMINE" AND CHITRA B. DIVAKARUNI’S "THE MISTRESS OF SPICES"

    2016-04-01

    Full Text Available The purpose of this article is to focus on the issue of marginalization of South Asians in the United States as portrayed in two novels written by writers of Indian origin: Bharati Mukherjee’s "Jasmine" and Chitra Bannerjee Divakaruni’s "The Mistress of Spices". It is investigated how race or skin color are the reasons for the marginalization of Indian immigrants in the United States. While "Jasmine" shows white Americans’ inability to embrace the racial difference of an Indian immigrant, which may be read as a reflection of the relative newness of this ethnic group in the United States and its shifting racial classification, "The Mistress of Spices" shows that the patterns of marginalization based on skin color may be developed already in the homeland, India, and then transferred to the US and confronted with the country’s racial diversity. Divakaruni’s novel raises a discussion of how the appreciation of whiteness developed in the country of birth leads to the hierarchical relations between the members of the Indian diaspora, and how it affects their relations with other American minorities. In this way, it shows that marginalization based on skin color is not only the outcome of inter-ethnic encounters but it can be an internal problem of this ethnic group as well.

    This article investigates the individual and contextual roles of race on welfare sanctions: benefit cuts for failing to comply with work or other behavioral requirements under the Temporary Assistance for Needy Families program. Using six years of federal administrative data, I advance previous welfare research by providing a nationally representative analysis of participant-, county-, and state-level predictors of welfare sanctioning. Using theories of racial classification, racialized social systems, and racial threat as guiding frameworks, I find that black and Latina women are at a greater risk of being sanctioned than white women. Further, although odds of a sanction are slightly reduced for black women living in counties with greater percentages of blacks, the opposite holds for Latinas, who are at an increased risk of being sanctioned in counties with greater percentages of Latinos.

We calculated the relative risk (RR for age, sex and underlying cause (p<0.05 and CI 95%. RESULTS: The completeness of race/color in SIM ranged from 1% in 1996 to 81% in 2006. There was a greater RR of death among blacks for mental and behavioral disorders (RR=9.29, Ill-defined causes (RR=8.71, and external causes (RR=5.71. For black women, we highlight the external causes (RR=2.38. We found a variation of up to 33 years (nervous system between whites and blacks. CONCLUSION: This study confirms the existence of unequal racial/ethnic mortality, highlighting the mortality from mental disorders and external causes, in addition to early mortality that occurs in the black population.

  20. Black Teenage Pregnancy

    Full Text Available This article examines the relative importance of race and socioeconomic status (SES in determining whether Black and White teenagers report having ever been pregnant. Data gathered from 1999 to 2006 by the National Center for Health Statistics of the Center for Disease Control and Prevention included 1,580 Black and White females aged 15 to 19 years. Results supported the effects of race and SES, with SES having the stronger effect. However, the effects of race and SES differ when controlling for the state of the economy. No difference between Blacks and Whites was found during better economic times. During 2003-2004, the period of greatest economic stress, race was determined to be the only predictor of teenage pregnancy. In particular, during 2005-2006, the reduction in pregnancy rates for Black minors (15-17 fell below those for White minors within their respective SES categories. Policy implications are discussed in light of these findings.

    Nutrient trials differ from drug trials because participants have varying circulating levels at entry into the trial. We sought to study the effect of a vitamin D intervention in pregnancy between subjects of different races and the association between 25-hydroxyvitamin D 3 (25[OH]D) levels in pregnancy and the risk of asthma/recurrent wheeze in offspring. The Vitamin D Antenatal Asthma Reduction Trial is a randomized trial of pregnant women at risk of having children with asthma randomized to 4400 international units/d vitamin D or placebo plus 400 international units/d vitamin D. Asthma and recurrent wheezing until age 3 years were recorded. African American (AA) women (n = 312) had lower initial levels of 25(OH)D (mean [SD], 17.6 ng/mL [8.3 ng/mL]) compared with non-AA women (n = 400; 27.1 ng/mL [9.7 ng/mL], P asthma/recurrent wheezing in offspring (P for interaction = .77). Having an initial level of greater than 30 ng/mL and being randomized to the intervention group was associated with the lowest risk for asthma/recurrent wheeze by age 3 years compared with having an initial level of less than 20 ng/mL and receiving placebo (adjusted odds ratio, 0.42; 95% CI, 0.19-0.91). We did not find differences between AA and non-AA mothers in the effect of maternal vitamin D supplementation and asthma/recurrent wheeze in offspring at 3 years. Maternal supplementation of vitamin D, particularly in mothers with initial 25(OH)D levels of greater than 30 ng/mL, reduced asthma/recurrent wheeze in the offspring through age 3 years, suggesting that higher vitamin D status beginning in early pregnancy is necessary for asthma/recurrent wheeze prevention in early life.

    Racial/ethnic disparities in birth weight persist within the USA. The purpose of this study is to examine the association between maternal everyday discrimination and infant birth weight among young, urban women of color as well as mediators (depressive symptoms, pregnancy distress, and pregnancy symptoms) and moderators (age, race/ethnicity, and attributions of discrimination) of this association. A total of 420 women participated (14-21 years old; 62 % Latina, 38 % Black), completing measures of everyday discrimination and moderators during their second trimester of pregnancy and mediators during their third trimester. Birth weight was primarily recorded from medical record review. Path analysis demonstrated that everyday discrimination was associated with lower birth weight. Depressive symptoms mediated this relationship, and no tested factors moderated this relationship. Given the association between birth weight and health across the lifespan, it is critical to reduce discrimination directed at young, urban women of color so that all children can begin life with greater promise for health.

    ún raza/color de la piel. MÉTODOS: Se realizó estudio descriptivo en Salvador, BA, con 9.626 registros de óbitos por causas externas entre 1998 y 2003. Los datos se obtuvieron del Instituto Médico Legal e Instituto Brasilero de Geografía y Estadística. El indicador "años potenciales de vida perdidos" fue utilizado para identificar diferenciales entre grupos erarios, de raza/color de la piel y sexo. RESULTADOS: Las muertes por causas externas determinaron pérdida de 339.220 años potenciales de vida, de los cuales 210.000 fueron debidos a los homicidios. Individuos negros murieron en edades más precoces y perdieron 12,2 veces más años potenciales de vida debido a homicidios que individuos blancos. A pesar de que la población negra (pardos y negros era tres veces mayor que la población blanca, el número de años perdidos de la primera fue 30 veces superior. La población de negros era 11,4% menor que la población blanca, pero presentó años perdidos casi tres veces mayor. Aún después de la estandarización por edad, se mantuvo las diferencias observadas en el indicador de años potenciales perdidos/100.000 hab y en las razones entre estratos según raza/color. CONCLUSIONES: Los resultados muestran diferenciales en la mortalidad por causas externas según raza/color de la piel en Salvador. Los negros tuvieron mayor pérdida de años potenciales de vida, mayor número promedio de años no vividos y murieron, en promedio, en edades más precoces por homicidios, accidentes de tránsito y demás causas externas.OBJECTIVE: Deaths by external causes represent one of the most important challenges for public health and are the second cause of death in Brazil.

    目的:了解正常中晚期妊娠输尿管的尿动力学改变是否影响输尿管射尿。方法:彩色多普勒超声观察32例中晚期妊娠妇女和11例非妊娠对照者膀胱射尿情况,观察时间5分钟。结果:妊娠受试者平均射尿5.9次/分,左、右侧射尿频率平均差异百分比为49%。对照组平均射尿7.3次/分,左、右射尿频率差异百分比为13%。受试组与对照组之间射尿对称性方面具有显著性差异(P<0.05)。32例妊娠受试者中有7例有单侧射尿缺乏,而对照者中无1例单侧射尿缺乏。结论:在妊娠中晚期,由于两侧输尿管射尿的不对称性,用彩色多普勒超声检测输尿管射尿诊断中晚期妊娠合并输尿管结石应慎用。%Objective: To understand whether ureteral urodynamic changes accompanying normal second- and third-trimester pregnancy altered the pattern of ureteral jets. Methods: Ureteral jets were observed with color Doppler sonography for five minutes in 32women during the second or third trimester of pregnancy and in 11 non-pregnant controls. Result: A mean of 5.9 jets/ minute were detected in the pregnant subjects. The mean percentage difference in frequency of jets between the right and left sides was 49%. A mean of 7.3 jets/ minute were detected and the mean percentage difference was 13% for controls. The two groups were significantly different in jet symmetry (P<0.05). Unilateral absence of jets was observed in seven pregnant subjects and in no controls. Conclusion: Because of asymmetry in ureteral jet between the left and right sides during the later stages of pregnacy, caution is recommended in the use of color Doppler sonography to diagnose ureteral urolithiasis during the later stages of pregnancy.

    2017-01-01

    A transient color flux across null infinity in classical Yang-Mills theory is considered. It is shown that a pair of test `quarks' initially in a color singlet generically acquire net color as a result of the flux. A nonlinear formula is derived for the relative color rotation of the quarks. For weak color flux the formula linearizes to the Fourier transform of the soft gluon theorem. This color memory effect is the Yang-Mills analog of the gravitational memory effect.

    2017-05-01

    We present a faster and noise-free implementation of the RACE algorithm. RACE has mixed characteristics between the famous Retinex model of Land and McCann and the automatic color equalization (ACE) color-correction algorithm. The original random spray-based RACE implementation suffers from two main problems: its computational time and the presence of noise. Here, we will show that it is possible to adapt two techniques recently proposed by Banić et al. to the RACE framework in order to drastically decrease the computational time and noise generation. The implementation will be called smart-light-memory-RACE (SLMRACE).

    Mulligan, Jeffrey B.

    2017-01-01

    A color algebra refers to a system for computing sums and products of colors, analogous to additive and subtractive color mixtures. The difficulty addressed here is the fact that, because of metamerism, we cannot know with certainty the spectrum that produced a particular color solely on the basis of sensory data. Knowledge of the spectrum is not required to compute additive mixture of colors, but is critical for subtractive (multiplicative) mixture. Therefore, we cannot predict with certainty the multiplicative interactions between colors based solely on sensory data. There are two potential applications of a color algebra: first, to aid modeling phenomena of human visual perception, such as color constancy and transparency; and, second, to provide better models of the interactions of lights and surfaces for computer graphics rendering.

    2007-05-01

    The main aim of this work was to assess the effect of lactation period on the secretion of carotenoids in cow's milk. Our objective was to determine the variations in carotenoids in the plasma and milk of dairy cows from drying off to wk 12 of lactation, and to specify whether these variations depend on body stores of these micronutrients at calving. We also investigated the relationship between beta-carotene (BC) and color in plasma and milk to evaluate the methods based on direct or indirect characterization of these micronutrients for traceability of feeding management. The experiment was carried out on 18 dairy cows, which were dried off 8 wk before their expected date of parturition. They were then divided into 2 homogeneous groups and fed diets contrasting in carotenoid content, high (grass silage) vs. low (corn silage), from wk -7 until parturition. From parturition through wk 12 of lactation, both groups received a grass silage-based diet. Variations in concentrations of carotenoids and the color index (CI) in plasma and milk were monitored from drying off to wk 12 of lactation. Other components of nutritional interest (i.e., vitamins A and E) were also measured. Lutein, all-trans BC and cis-13 BC were the carotenoids found in plasma and milk. Plasma concentrations of carotenoids, vitamin A, and vitamin E decreased throughout the dry period and in the first week of lactation, then increased through the first 3 mo of lactation, parallel to grass silage intake. For both groups, carotenoid and vitamin concentrations in milk drastically decreased during the first week of lactation, then did not vary significantly throughout the remainder to the experiment (wk 12). Plasma concentrations of carotenoids and vitamins were higher in the high-carotenoid group than in the low-carotenoid group during the dry period. Those differences were also observed in colostrum and disappeared in both plasma and milk during the first 10 d of the lactation period. This work allowed

  12. Neural correlates of memory encoding and recognition for own-race and other-race faces in an associative-memory task.

    Herzmann, Grit; Minor, Greta; Adkins, Makenzie

    2017-01-15

    The ability to recognize faces of family members, friends, and acquaintances plays an important role in our daily interactions. The other-race effect is the reduced ability to recognize other-race faces as compared to own-race faces. Previous studies showed different patterns of event-related potentials (ERPs) associated with recollection and familiarity during memory encoding (i.e., Dm) and recognition (i.e., parietal old/new effect) for own-race and other-race faces in a subjective-recollection task (remember-know judgments). The present study investigated the same neural correlates of the other-race effect in an associative-memory task, in which Caucasian and East Asian participants learned and recognized own-race and other-race faces along with background colors. Participants made more false alarms for other-race faces indicating lower memory performance. During the study phase, subsequently recognized other-race faces (with and without correct background information) elicited more positive mean amplitudes than own-race faces, suggesting increased neural activation during encoding of other-race faces. During the test phase, recollection-related old/new effects dissociated between own-race and other-race faces. Old/new effects were significant only for own-race but not for other-race faces, indicating that recognition only of own-race faces was supported by recollection and led to more detailed memory retrieval. Most of these results replicated previous studies that used a subjective-recollection task. Our study also showed that the increased demand on memory encoding during an associative-memory task led to Dm patterns that indicated similarly deep memory encoding for own-race and other-race faces.

    Fawkes, S.

    This paper compares and contrasts the characteristics of the first space race, which ran from the late 1950s to the late 1990s, and the second space race that began with the successful space flight of SpaceShipOne in 2004. The first space race was between superpowers seeking to establish geo-political dominance in the Cold War. The second space race will be between competing companies seeking to establish low cost access to space for ordinary people. The first space race achieved its geo- political objectives but did not open up low cost access to space but rather restricted access to a select few, highly trained astronauts and cosmonauts. The second space race, driven by the size and growth of the travel and tourism industry, promises to open up access to space to millions of space tourists.

  17. Color Analysis

    Science.gov (United States)

    Wrolstad, Ronald E.; Smith, Daniel E.

    Color, flavor, and texture are the three principal quality attributes that determine food acceptance, and color has a far greater influence on our judgment than most of us appreciate. We use color to determine if a banana is at our preferred ripeness level, and a discolored meat product can warn us that the product may be spoiled. The marketing departments of our food corporations know that, for their customers, the color must be "right." The University of California Davis scorecard for wine quality designates four points out of 20, or 20% of the total score, for color and appearance (1). Food scientists who establish quality control specifications for their product are very aware of the importance of color and appearance. While subjective visual assessment and use of visual color standards are still used in the food industry, instrumental color measurements are extensively employed. Objective measurement of color is desirable for both research and industrial applications, and the ruggedness, stability, and ease of use of today's color measurement instruments have resulted in their widespread adoption.

  18. Color categories and color appearance

    Webster, Michael A.; Kay, Paul

    2011-01-01

    We examined categorical effects in color appearance in two tasks, which in part differed in the extent to which color naming was explicitly required for the response. In one, we measured the effects of color differences on perceptual grouping for hues that spanned the blue–green boundary, to test whether chromatic differences across the boundary were perceptually exaggerated. This task did not require overt judgments of the perceived colors, and the tendency to group showed only a weak and inconsistent categorical bias. In a second case, we analyzed results from two prior studies of hue scaling of chromatic stimuli (De Valois, De Valois, Switkes, & Mahon, 1997; Malkoc, Kay, & Webster, 2005), to test whether color appearance changed more rapidly around the blue–green boundary. In this task observers directly judge the perceived color of the stimuli and these judgments tended to show much stronger categorical effects. The differences between these tasks could arise either because different signals mediate color grouping and color appearance, or because linguistic categories might differentially intrude on the response to color and/or on the perception of color. Our results suggest that the interaction between language and color processing may be highly dependent on the specific task and cognitive demands and strategies of the observer, and also highlight pronounced individual differences in the tendency to exhibit categorical responses.

  19. Race: Deflate or pop?

    Neven Sesardic has recently defended his arguments in favour of racial naturalism-the view that race is a valid biological category-in response to my criticism of his work. While Sesardic claims that a strong version of racial naturalism can survive critique, he has in fact weakened his position considerably. He concedes that conventional racial taxonomy is arbitrary and he no longer identifies 'races' as human subspecies. Sesardic now relies almost entirely on Theodosius Dobzhansky's notion of race-as-population. This weak approach to 'race'-according to which all genetic difference between populations is 'racial' and 'the races' are simply the populations we choose to call races-survived its early critiques. As it is being mobilised to support racial naturalism once more, we need to continue the debate about whether we should weaken the concept of race to mean 'population', or abandon it as a failed biological category. I argue that Sesardic's case for racial naturalism is only supported by his continued mischaracterisation of anti-realism about biological race and his appeal to Dobzhansky's authority. Rather than deflating the meaning of 'race', it should be eliminated from our biological ontology. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2016-01-01

    The subject of this book is the theory of operads and colored operads, sometimes called symmetric multicategories. A (colored) operad is an abstract object which encodes operations with multiple inputs and one output and relations between such operations. The theory originated in the early 1970s in homotopy theory and quickly became very important in algebraic topology, algebra, algebraic geometry, and even theoretical physics (string theory). Topics covered include basic graph theory, basic category theory, colored operads, and algebras over colored operads. Free colored operads are discussed in complete detail and in full generality. The intended audience of this book includes students and researchers in mathematics and other sciences where operads and colored operads are used. The prerequisite for this book is minimal. Every major concept is thoroughly motivated. There are many graphical illustrations and about 150 exercises. This book can be used in a graduate course and for independent study.

    Full Text Available The goal of this article is to present specific capabilities and limitations of the use of color digital images in a characterization process. The whole process is investigated, from the acquisition of digital color images to the analysis of the information relevant to various applications in the field of material characterization. A digital color image can be considered as a matrix of pixels with values expressed in a vector-space (commonly 3 dimensional space whose specificity, compared to grey-scale images, is to ensure a coding and a representation of the output image (visualisation printing that fits the human visual reality. In a characterization process, it is interesting to regard color image attnbutes as a set of visual aspect measurements on a material surface. Color measurement systems (spectrocolorimeters, colorimeters and radiometers and cameras use the same type of light detectors: most of them use Charge Coupled Devices sensors. The difference between the two types of color data acquisition systems is that color measurement systems provide a global information of the observed surface (average aspect of the surface: the color texture is not taken into account. Thus, it seems interesting to use imaging systems as measuring instruments for the quantitative characterization of the color texture.

    represent vulnerability to sickness, this study attempts to verify whether race or ethnic origin have an effect on mortality patterns. METHODS: The Sao Paulo State death register was examined from 1999 to 2001 in a contingence table of causes according to the 10th ICD and race or skin-color categories (White, Black, Mulatto and others. Chi-square test was used to check the association between skin-color and cause of death; residual analysis was used to elicit statistically significant excessive occurrences when each category of cause of death and skin color was combined; and correspondence analysis was used to examine overall relations among all categories considered. RESULTS: A total of 647,321 valid death registers were analyzed, among which 77.7% were of Whites, 5.4% of Blacks, 14.3% of Mulattoes and 2.6% of others. A significant association between skin color or race and cause of death was found. It may be observed that, although Blacks and Mulattoes present a similar death profile, on the contrary of Whites and others, which could be aggregated into a single category, the former appear in distinct positions on the multidimensional map presented. Except for mal defined causes, which characterize only the deaths of Blacks, the other causes of death within this group are common to both Blacks and Mulattoes, varying however, in intensity and as to the order in which they appear death. CONCLUSIONS: Analysis of mortality according to race or color revealed that death has a color. There is a White death, which has, among its causes, sicknesses, which, although variable, are nothing more than sicknesses. There's a Black death, which is not caused by sicknesses but by external causes, complications in labor and delivery, mental disorders and ill- defined causes.

    2012-01-01

    Any analogy between race and homosexuality cannot erase the fact that skin color has marked and continues to mark bodies for special punishment and necessary protection. Yet, the analogy has also been forged in the struggles against sexual discrimination and in the courts to recognize same-sex marriage as a basic civil right. My purposes here are, first, to review the role the race-sexual orientation analogy has played in same-sex marriage debates, second to examine the analogy within the context of race and queer theories and, finally, to suggest a racial dimension to sexuality that marks the homosexual body.

    [figure removed for brevity, see original site] Released 7 May 2004 This daytime visible color image was collected on May 30, 2002 during the Southern Fall season in Atlantis Chaos. The THEMIS VIS camera is capable of capturing color images of the martian surface using its five different color filters. In this mode of operation, the spatial resolution and coverage of the image must be reduced to accommodate the additional data volume produced from the use of multiple filters. To make a color image, three of the five filter images (each in grayscale) are selected. Each is contrast enhanced and then converted to a red, green, or blue intensity image. These three images are then combined to produce a full color, single image. Because the THEMIS color filters don't span the full range of colors seen by the human eye, a color THEMIS image does not represent true color. Also, because each single-filter image is contrast enhanced before inclusion in the three-color image, the apparent color variation of the scene is exaggerated. Nevertheless, the color variation that does appear is representative of some change in color, however subtle, in the actual scene. Note that the long edges of THEMIS color images typically contain color artifacts that do not represent surface variation. Image information: VIS instrument. Latitude -34.5, Longitude 183.6 East (176.4 West). 38 meter/pixel resolution. Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release. An empirical correction has been performed to remove instrumental effects. A linear shift has been applied in the cross-track and down-track direction to approximate spacecraft and planetary motion. Fully calibrated and geometrically projected images will be released through the Planetary Data System in accordance with Project policies at a later time.

    Group models of prenatal care continue to grow in popularity. However, little is known about how group composition (similarity or diversity between members of groups) relates to care-related outcomes. The current investigation aimed to explore associations between prenatal care group composition with patient satisfaction, engagement, and group attendance among young, urban women of color. Data were drawn from two studies conducted in New Haven and Atlanta (2001-2004; n = 557) and New York City (2008-2011; n = 375) designed to evaluate group prenatal care among young, urban women of color. Women aged 14 to 25 were assigned to group prenatal care and completed surveys during their second and third trimesters of pregnancy. Group attendance was recorded. Data were merged and analyzed guided by the Group Actor-Partner Interdependence Model using multilevel regression. Analyses explored composition in terms of age, race, ethnicity, and language. Women in groups with others more diverse in age reported greater patient engagement and, in turn, attended more group sessions, b(se) = -0.01(0.01); p = .04. The composition of prenatal care groups seems to be associated with young women's engagement in care, ultimately relating to the number of group prenatal care sessions they attend. Creating groups diverse in age may be particularly beneficial for young, urban women of color, who have unique pregnancy needs and experiences. Future research is needed to test the generalizability of these exploratory findings. Copyright © 2016 Jacobs Institute of Women's Health. Published by Elsevier Inc. All rights reserved.

  10. Colored leptons

    International Nuclear Information System (INIS)

    Harari, H.

    1985-01-01

    If leptons are composite and if they contain colored preons, one expects the existence of heavy color-octet fermions with quantum numbers similar to those of ordinary leptons. Such a ''colored lepton'' should decay into a gluon and a lepton, yielding a unique experimental signature. Charged ''colored leptons'' probably have masses of the order of the compositeness scale Λ > or approx. 1 TeV. They may be copiously produced at future multi-TeV e + e - , ep and hadron colliders. ''Colored neutrinos'' may have both Dirac and Majorana masses. They could be much lighter than Λ, possibly as light as 100 GeV or less. In such a case they should be readily produced at the CERN anti pp collider, yielding spectacular monojet and dijet events. They may also be produced at LEP and HERA. (orig.)

  18. Race and gender discrimination in the Marines.

    Foynes, Melissa Ming; Shipherd, Jillian C; Harrington, Ellen F

    2013-01-01

    Although women of color have been hypothesized to experience double jeopardy in the form of chronic exposure to both race-based (RBD) and gender-based discrimination (GBD; Beal, 1970), few empirical investigations that examine both RBD and GBD in multiple comparison groups have been conducted. In addition to being one of the only simultaneous examinations of RBD and GBD in multiple comparison groups, the current study includes both self-report and objective behavioral data to examine the independent and interactive effects of both forms of discrimination. This study is also the first of its kind to examine these constructs in these ways and to explore their impact in a unique sample of ethnically diverse male and female Marine recruits (N = 1,516). As anticipated, both RBD and GBD had a strong and consistent negative impact on mental health symptoms (e.g., depression, anxiety), independent of the contributions of gender and race. Partial support was found for the hypothesis that people of color are able to maintain resiliency (as measured by physical fitness testing) in the face of low levels of RBD, but are less able to overcome the negative effects of discrimination at high levels. It is interesting to note that the interaction between race, gender, and levels of discrimination was only found with objective physical fitness test scores but not with self-report measures. These findings underscore the importance of including objective measures when assessing the impact of discrimination in order to understand these complex interrelationships.

  19. Do blind people see race? Social, legal, and theoretical considerations.

    Science.gov (United States)

    Obasogie, Osagie K

    2010-01-01

    Although the meaning, significance, and definition of race have been debated for centuries, one thread of thought unifies almost all of the many diverging perspectives: a largely unquestioned belief that race is self-evident and visually obvious, defined largely by skin color, facial features, and other visual cues. This suggests that “seeing race” is an experience largely unmediated by broader social forces; we simply know it when we see it. It also suggests that those who cannot see are likely to have a diminished understanding of race. But is this empirically accurate?I examine these questions by interviewing people who have been totally blind since birth about race and compare their responses to sighted individuals. I not only find that blind people have as significant an understanding of race as anyone else and that they understand race visually, but that this visual understanding of race stems from interpersonal and institutional socializations that profoundly shape their racial perceptions. These findings highlight how race and racial thinking are encoded into individuals through iterative social practices that train people to think a certain way about the world around them. In short, these practices are so strong that even blind people, in a conceptual sense, “see” race. Rather than being self-evident, these interviews draw attention to how race becomes visually salient through constitutive social practices that give rise to visual understandings of racial difference for blind and sighted people alike. This article concludes with a discussion of these findings' significance for understanding the role of race in law and society.

    To explore racial/ethnic differences in reproductive coercion (RC), intimate partner violence (IPV), and unintended pregnancy (UIP). We analyzed cross-sectional, baseline data from an intervention that was conducted between August 2008 and March 2009 in five family planning clinics in the San Francisco, California area, to examine the association of race/ethnicity with RC, IPV, and UIP among female patients aged 16-29 (n = 1234). RC was significantly associated with race/ethnicity, p women, with an overall range of 37.1%-50.3% among all racial/ethnic groups (p women (AOR = 1.72, 95% CI = 1.14-2.60). Black and multiracial women seeking care in family planning clinics have a disproportionately high prevalence of RC and UIP. RC may partially explain differences in UIP prevalence, with the effect of race/ethnicity slightly attenuated in RC-adjusted models. However, the impact of RC on risk for UIP was similar for White and Black women. Findings from this study support the need to understand and prevent RC, particularly among women of color. Results are foundational in understanding disparities in RC and UIP that may have implications for refinement of clinical care.

    2015-02-01

    Research in the 1980s pointed to the lower marriage rates of blacks as an important factor contributing to race differences in non-marital fertility. Our analyses update and extend this prior work to investigate whether cohabitation has become an important contributor to this variation. We use data from the 2006-2010 National Survey of Family Growth (NSFG) and to identify the relative contribution of population composition (i.e. percent sexually active single and percent cohabiting) versus rates (pregnancy rates, post-conception marriage rates) to race-ethnic variation in non-marital fertility rates (N=7,428). We find that the pregnancy rate among single (not cohabiting) women is the biggest contributor to race-ethnic variation in the non-marital fertility rate and that contraceptive use patterns among racial minorities explains the majority of the race-ethnic differences in pregnancy rates.

  7. Race, money and medicines.

    Science.gov (United States)

    Bloche, M Gregg

    2006-01-01

    Taking notice of race is both risky and inevitable, in medicine no less than in other endeavors. On the one hand, race can be a useful stand-in for unstudied genetic and environmental factors that yield differences in disease expression and therapeutic response. Attention to race can make a therapeutic difference, to the point of saving lives. On the other hand, racial distinctions have social meanings that are often pejorative or worse, especially when these distinctions are cast as culturally or biologically fixed. I argue in this essay that we should start with a presumption against racial categories in medicine, but permit their use when it might prolong lives or meaningfully improve health. Use of racial categories should be understood as an interim step; follow-up inquiry into the factors that underlie race-correlated clinical differences is important both to improve the efficacy of clinical care and to prevent race in itself from being misunderstood as a biological determinant. If we pursue such inquiry with vigor, the pernicious effects of racial categories on public understanding can be managed. But perverse market and regulatory incentives create the danger that use of race will be "locked-in," once drugs or other therapies are approved. These incentives should be revisited.

He wandered whether arms control could ensure this balance and whether nuclear balance meant force balance. Force balance then appears to be a precarious and unsteady component of international security. He commented the challenges of disarmament, recalled some arguments for a nuclear disarmament. Then he discussed what would be an arms control with or without disarmament (either nuclear or conventional)

    The anomously large transmission of nucleons through a nucleus following a hard collision is explored. This effect, known as color transparency, is believed to be a prediction of QCD. The necessary conditions for its occurrence and the effects that must be included a realistic calculation are discussed

  20. Color transparency

    International Nuclear Information System (INIS)

    Miller, G.A.

    1993-01-01

    Imagine shooting a beam of protons of high momentum P through an atomic nucleus. Usually the nuclear interactions prevent the particles from emerging with momentum ∼P. Further, the angular distribution of elastically scattered protons is close to the optical diffraction pattern produced by a black disk. Thus the nucleus acts as a black disk and is not transparent. However, certain high momentum transfer reactions in which a proton is knocked out of the nucleus may be completely different. Suppose that the high momentum transfer process leads to the formation of a small-size color singlet wavepacket that is ejected from the nucleus. The effects of gluons emitted by color singlet systems of closely separated quarks and gluons tend to cancel. Thus the wavepacket-nuclear interactions are suppressed, the nucleus becomes transparant and one says that color transparency CT occurs. The observation of CT also requires that the wavepacket not expand very much while it moves through the nucleus. Simple quantum mechanical formulations can assess this expansion. The creation of a small-sized wavepacket is expected in asymptotic perturbative effects. The author reviews the few experimental attempts to observe color transparency in nuclear (e,e'p) and (p,pp) reactions and interpret the data and their implications

    Heat strain is a potential risk factor for racing greyhounds in hot climates. However, there have been limited studies into the incidence of heat strain (when excess heat causes physiological or pathological effects) in racing greyhounds. The aim of this study was to determine if heat strain occurs in racing greyhounds, and, if so, whether environmental factors (e.g., ambient temperature and relative humidity) or dog-related factors (e.g., sex, bodyweight, color) are associated with the risk of heat strain. A total of 229 greyhounds were included in over 46 race meetings and seven different race venues in South Australia, Australia. Rectal temperatures of dogs were measured pre- and postrace and urine samples collected for analysis of myoglobinuria. Ambient temperature at race times ranged between 11.0 and 40.8°C and relative humidity ranged from 17 to 92%. There was a mean increase in greyhound rectal temperature of 2.1°C (range 1.1-3.1°C). A small but significant association was present between ambient temperature and increase in rectal temperature (r (2) = 0.033, P = 0.007). The mean ambient temperature at race time, of dogs with postrace rectal temperature of or exceeding 41.5°C, was significantly greater than at race time of dogs with a postrace rectal temperature ≤41.5°C (31.2 vs. 27.3°C, respectively, P = 0.004). When the ambient temperature reached 38(o)C, over one-third (39%) of dogs had a rectal temperature >41.5°C. Over half of postrace urine samples were positive by Dipstick reading for hemoglobin/myoglobin, and of 77 urine samples positive for Dipstick readings, 95% were positive for myoglobin. However, urinary myoglobin levels were not associated with ambient temperature or postrace rectal temperatures. The mean increase in rectal temperature was greater in dark (black, blue, brindle) than light (fawn and white) colored greyhounds. The results suggest heat strain occurs in racing greyhounds, evidenced by postrace rectal

Trata-se de revisão sistemática, conduzida na base PubMed,entre janeiro de 2000 e julho de 2010. Para o conjunto dos trabalhos revisados, aplicou-se ficha com questões sobre seus objetivos e a relevância da classificação étnico-racial em suas análises, características sócio-demográficas e aspectos da identificação étnico-racial das populações investigadas, bem como o seguimento de recomendações quanto ao uso das classificações de raça, cor e etnia. Dos 1.174 artigos identificados, 151 foram elegíveis para a revisão. Maiores proporções de cada um dos seguintes aspectos foram observadas nos artigos em que a identificação étnico-racial ocupou papel central em suas análises - destes, 18% justificaram o emprego das categorias; 16% consideraram a classificação étnico-racial como fluida e relativa ao contexto da produção dos dados; 65% descreveram o método da classificação étnico-racial; 17% entenderam esta classificação como medida de variabilidade genética; 26% interpretaram a variável como fator de risco para o desfecho em questão; 47% consideraram fatores socioeconômicos na interpretação das desigualdades étnico-raciais; e 27% incluíram tais fatores no ajuste de modelos estatísticos. Apenas dois estudos explicitaram o conceito, que embasou o uso da variável étnico-racial. Uma proporção expressiva dos estudos epidemiológicos analisados não segue os critérios mínimos que vêm sendo sugeridos quanto ao uso de variáveis relacionadas à classificação étnico-racial, de modo que este aspecto deve ser aperfeiçoado nas pesquisas em Saúde Coletiva.This paper aims to analyze the use of the variables race, color and ethnicity in epidemiologic studies, carried out with Brazilian populations.

    2006-01-01

    Race car performance depends on elements such as the engine, tires, suspension, road, aerodynamics, and of course the driver. In recent years, however, vehicle aerodynamics gained increased attention, mainly due to the utilization of the negative lift (downforce) principle, yielding several important performance improvements. This review briefly explains the significance of the aerodynamic downforce and how it improves race car performance. After this short introduction various methods to generate downforce such as inverted wings, diffusers, and vortex generators are discussed. Due to the complex geometry of these vehicles, the aerodynamic interaction between the various body components is significant, resulting in vortex flows and lifting surface shapes unlike traditional airplane wings. Typical design tools such as wind tunnel testing, computational fluid dynamics, and track testing, and their relevance to race car development, are discussed as well. In spite of the tremendous progress of these design tools (due to better instrumentation, communication, and computational power), the fluid dynamic phenomenon is still highly nonlinear, and predicting the effect of a particular modification is not always trouble free. Several examples covering a wide range of vehicle shapes (e.g., from stock cars to open-wheel race cars) are presented to demonstrate this nonlinear nature of the flow field.

    The aim of this study was to determine the relationships between biomechanical parameters of the gait cycle and race walking economy in world-class Olympic race walkers. Twenty-One world-class race walkers possessing the Olympic qualifying standard participated in this study. Participants completed an incremental race walking test starting at 10 km·h -1 , where race walking economy (ml·kg -1 ·km -1 ) and spatiotemporal gait variables were analysed at different speeds. 20-km race walking performance was related to race walking economy, being the fastest race walkers those displaying reduced oxygen cost at a given speed (R = 0.760, p < 0.001). Longer ground contact times, shorter flight times, longer midstance sub-phase and shorter propulsive sub-phase during stance were related to a better race walking economy (moderate effect, p < 0.05). According to the results of this study, the fastest race walkers were more economi cal than the lesser performers. Similarly, shorter flight times are associated with a more efficient race walking economy. Coaches and race walkers should avoid modifying their race walking style by increasing flight times, as it may not only impair economy, but also lead to disqualification.

    Maternal pre-pregnancy overweight and obese status has been associated with a number of pregnancy complications and adverse offspring outcomes. Mechanisms for observed associations, however, are largely unknown. We investigated associations of pre-pregnancy body mass index with early-mid pregnancy epigenetic biomarkers, circulating microRNAs. Peripheral blood was collected from participants (16-27 weeks gestation) of two multi-racial pregnancy cohorts, the Omega Study and the Pregnancy Outcomes and Community Health Study. Plasma miRNA expression was characterised using epigenome-wide (319 miRNAs) profiling among 20 pregnant women in each cohort. Cohort-specific linear regression models that included the predictor (pre-pregnancy body mass index), the outcome (microRNA expression), and adjustment factors (maternal age, gestational age at blood collection, and race) were fit. Expression of 27 miRNAs was positively associated with pre-pregnancy body mass index in both cohorts (p-values pregnancy body mass index is associated with circulating miRNAs in early-mid pregnancy.

    Dating back nearly 2000 years, the ancient Chinese tradition of Dragon Boat Racing was originally a celebration that fell on the 5th day of the 5th lunar month as a gesture to please the Gods and bring forth necessary rains to cultivate the lands. Now the CERN Canoe and Kayak Club, too, participates in this tradition, though not so much to please the Gods on the ritualistic date, but to bring forth giant smiles on the faces of members. Dragon Boat Racing has been rising steadily in popularity in Europe since the mid nineties and with the great potential to host and promote Dragon Boat Racing in the Geneva area, the CERN Canoe and Kayak Club, has taken the initiative to bring the sport to the region. Some members of the Club traveled to Dole in June to participate in the Festival Dragon Boat 2009.

    Postpartum depression is associated with negative physical and mental health outcomes for both the mother and infant. This study examines the relationship between a mother and/or her partner's pregnancy intentions and reported post-partum depressive symptoms (PPDs). Using Louisiana pregnancy risk assessment monitoring system, 2000-2003, a secondary cross-sectional analysis was conducted on 5549 mothers, stratified by race, who delivered a singleton, live birth and whose infant was still alive at the time of the survey. Bivariate and multivariable logistic regressions were conducted, taking into account the complex survey design. In multivariable models, unwanted pregnancies were associated with severe PPDs (aOR 1.76, 95 % CI 1.23-2.53). Furthermore, the association between husbands/partners' who did not want or care about the pregnancy and mild PPDs remained for White women (aOR 1.32, 95 % CI 1.02-1.69); while among Black women, neither parent's pregnancy intention were associated with mild or severe PPDs. This study supports existing research demonstrating the association between pregnancy intention and PPDs. This study contributes to the limited information on the role that partner pregnancy intention plays on maternal mental health outcomes, however further discussion is needed on the impact of this role across races. Findings can be used in programs aiming to reduce adverse mental health outcomes among high-risk mothers.

This would explain why even fundamentally different languages have distinct color terms for these focal colors, and why unique hues play a prominent role in subjective color appearance. In this study, the subjective saturation of 10 colors around each of these focal colors was measured through a pairwise matching task. Results show that subjective saturation changes systematically across hues in a way that is strongly correlated to the visual gamut, and exponentially related to sensitivity but not to focal colors.

  17. Automatic color preference correction for color reproduction

    The reproduction of natural objects in color images has attracted a great deal of attention. Reproduction more pleasing colors of natural objects is one of the methods available to improve image quality. We developed an automatic color correction method to maintain preferred color reproduction for three significant categories: facial skin color, green grass and blue sky. In this method, a representative color in an object area to be corrected is automatically extracted from an input image, and a set of color correction parameters is selected depending on the representative color. The improvement in image quality for reproductions of natural image was more than 93 percent in subjective experiments. These results show the usefulness of our automatic color correction method for the reproduction of preferred colors.

    Standardization of color reproduction management is aimed at realization of the most urgently needed areas of the color reproduction management for international standardization. This R and D program is aimed at drafting the standards for color information devices and their characteristics, and proposing the drafts. Factors which deteriorate color reproduction stability of input and output devices are classified and analyzed, devices for evaluation are selected, and extents of the deterioration are measured and evaluated, in order to extract the problems involved in the color reproduction models for the current input and output devices. Standardization of color management on the multi-spectrum color images is attempted for business printing, where effectiveness of a fluorescent ink containing a fluorescent material is noted for expansion of the color reproduction range for printing color images with the conventional YMCK inks. Basic aspects of the fluorescent colors are measured, to verify the methods for measuring fluorescent body colors. As a result, new knowledge is obtained. The standard images for flesh color evaluation are produced, and the methods for analyzing the data obtained by the tests, including the subjective tests, are established. These lead to establishment of the standards for preferred flesh color of the yellow races. (NEDO)

  20. Why I Write So Many Books About Race

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available I relate how my life has intersected with my work in philosophy, both before and after a twenty-year absence from academia. Motivations for engaging in Philosophy of Race may be different from other projects because the subject itself is urgent and the philosopher may be a person of color. I describe the development of my own writing in this subfield, from ontological issues in the philosophy of science to moral issues in political philosophy and cultural criticism. The first addressed the biological reality of human racial taxonomy and the second has been about the inadequacy of treatments of race in the history of philosophy and injustice in contemporary social constructions of race.

    Two experiments explored the ramifications of endorsing color blindness as a strategy for appearing unprejudiced. In Study 1, Whites proved adept at categorizing faces on the basis of race, but understated their ability to do so. In Study 2, Whites playing the Political Correctness Game--a matching task that requires describing other individuals--were less likely to use race as a descriptor when paired with a Black partner than when paired with a White partner, a strategy that impaired communication and performance. In addition, avoidance of race was associated with Whites making less eye contact with and appearing less friendly toward Black partners.

  2. Cognitive aspects of color

    Derefeldt, Gunilla A. M.; Menu, Jean-Pierre; Swartling, Tiina

    1995-04-01

    This report surveys cognitive aspects of color in terms of behavioral, neuropsychological, and neurophysiological data. Color is usually defined as psychophysical color or as perceived color. Behavioral data on categorical color perception, absolute judgement of colors, color coding, visual search, and visual awareness refer to the more cognitive aspects of color. These are of major importance in visual synthesis and spatial organization, as already shown by the Gestalt psychologists. Neuropsychological and neurophysiological findings provide evidence for an interrelation between cognitive color and spatial organization. Color also enhances planning strategies, as has been shown by studies on color and eye movements. Memory colors and the color- language connections in the brain also belong among the cognitive aspects of color.

  3. Trends in pregnancies and pregnancy rates by outcome: estimates for the United States, 1976-96.

    Ventura, S J; Mosher, W D; Curtin, S C; Abma, J C; Henshaw, S

    2000-01-01

    This report presents national estimates of pregnancies and pregnancy rates according to women's age, race, and Hispanic origin, and by marital status, race, and Hispanic origin. Data are presented for 1976-96. Data from the National Survey of Family Growth (NSFG) are used to show information on sexual activity, contraceptive practices, and infertility, as well as women's reports of pregnancy intentions. Tables of pregnancy rates and the factors affecting pregnancy rates are presented and interpreted. Birth data are from the birth-registration system for all births registered in the United States and reported by State health departments to NCHS; abortion data are from The Alan Guttmacher Institute (AGI) and the National Center for Chronic Disease Prevention and Health Promotion, Centers for Disease Control and Prevention (CDC); and fetal loss data are from pregnancy history information collected in the NSFG. In 1996 an estimated 6.24 million pregnancies resulted in 3.89 million live births, 1.37 million induced abortions, and 0.98 million fetal losses. The pregnancy rate in 1996 was 104.7 pregnancies per 1,000 women aged 15-44 years, 9 percent lower than in 1990 (115.6), and the lowest recorded since 1976 (102.7). Since 1990 rates have dropped 8 percent for live births, 16 percent for induced abortions, and 4 percent for fetal losses. The teenage pregnancy rate has declined considerably in the 1990's, falling 15 percent from its 1991 high of 116.5 per 1,000 women aged 15-19 years to 98.7 in 1996. Among the factors accounting for this decline are decreased sexual activity, increases in condom use, and the adoption of the injectable and implant contraceptives.

    What is color? What is color vision? Most philosophers answer by reference to humans: to human color qualia, or to the environmental properties or "quality spaces" perceived by humans. It is argued, with reference to empirical findings concerning comparative color vision and the evolution of color vision, that all such attempts are mistaken. An adequate definition of color vision must eschew reference to its outputs in the human cognition and refer only to inputs: color vision consists in...

    In astronomy, the relationship between color and temperature is an important concept. This concept can be demonstrated in a laboratory or seen at telescope when observing stars. A blind/visually-impaired (B/VI) person would not be able to engage in the same observational demonstrations that are typically done to explain this concept. We’ve developed a tool for B/VI students to participate in these types of observational activities. Using an arduino compatible micro controller with and RGB light sensor, we are able to convert filtered light into sound. The device will produce different timbres for different wavelengths of light, which can then be used to distinguish the temperature of an object. The device is handheld, easy to program and inexpensive to reproduce (< $50). It is also fitted to mount on a telescope for observing. The design schematic and code will be open source and available for download.

    2017-10-01

    The logical empiricists expressed a consistent attitude to racial categorisation in both the ethical and scientific spheres. Their attitude may be captured in the following slogan: human racial taxonomy is an empirically meaningful mode of classifying persons that we should refrain from deploying. I offer an interpretation of their position that would render coherent their remarks on race with positions they adopted on the scientific status of taxonomy in general, together with their potential moral or political motivations for adopting that position.

  11. Using color management in color document processing

    Science.gov (United States)

    Nehab, Smadar

    1995-04-01

    Color Management Systems have been used for several years in Desktop Publishing (DTP) environments. While this development hasn't matured yet, we are already experiencing the next generation of the color imaging revolution-Device Independent Color for the small office/home office (SOHO) environment. Though there are still open technical issues with device independent color matching, they are not the focal point of this paper. This paper discusses two new and crucial aspects in using color management in color document processing: the management of color objects and their associated color rendering methods; a proposal for a precedence order and handshaking protocol among the various software components involved in color document processing. As color peripherals become affordable to the SOHO market, color management also becomes a prerequisite for common document authoring applications such as word processors. The first color management solutions were oriented towards DTP environments whose requirements were largely different. For example, DTP documents are image-centric, as opposed to SOHO documents that are text and charts centric. To achieve optimal reproduction on low-cost SOHO peripherals, it is critical that different color rendering methods are used for the different document object types. The first challenge in using color management of color document processing is the association of rendering methods with object types. As a result of an evolutionary process, color matching solutions are now available as application software, as driver embedded software and as operating system extensions. Consequently, document processing faces a new challenge, the correct selection of the color matching solution while avoiding duplicate color corrections.

    Teen pregnancy is a social problem not resolved in developing and some developed countries. Adolescent fecundity has become the most exact bio-demographic and health indicator of development. In developing countries that are expected to follow the sexual behaviour patterns of developed countries, without offering the levels of education and services for adolescents, the consequences will be adolescent fecundity and STI prevalence increase. The ignorance about sexuality and reproduction both in parents, teachers and adolescents increases the early initiation of coital relations and of unwanted pregnancies. Extreme poverty and being the son or daughter of an adolescent mother are risk factors of repeating the early pregnancy model. The application of predictive risk criteria in pregnant adolescents to facilitate the rational use of Health Services to diminish the maternal and perinatal mortality is discussed as well as the social factors associated with adolescent pregnancy as socioeconomic levels, structure - types and characteristics of the family, early leaving school, schooling after delivery, female employment, lack of sexual education, parental and family attitudes in different periods of adolescent pregnancy, adolescent decisions on pregnancy and children, unstable partner relationship and adoption as an option. Social consequences are analyzed as: incomplete education, more numerous families, difficulties in maternal role, abandonment by the partner, fewer possibilities of having a stable, qualified and well-paid job, greater difficulty in improving their socioeconomic level and less probability of social advancement, lack of protection of the recognition of the child. Finally, based on evidence, some measures that can reduce adverse consequences on adolescent mothers, fathers and their children are suggested. Copyright © 2012 S. Karger AG, Basel.

    Discrimination predicts increased risk for many negative health outcomes, helping explain a variety of racial and socioeconomic health disparities. Recent research suggests discrimination may play a role in disparities in HIV and other sexually transmitted infections (STIs); however, this research has focused on risk behaviors and has yet to establish a link between discrimination and STI diagnosis specifically. This investigation tested whether discrimination predicted condom use, risky sexual partners, and self-reported STI diagnosis among a population disproportionately affected by HIV and STIs in the U.S.: young, pregnant, socioeconomically disadvantaged, women of color. During second and third trimesters, 885 mostly Latina and Black pregnant women, 14-21 years old, attending 14 hospitals and health centers in New York City for prenatal care, completed interviews. Greater discrimination during second trimester predicted greater odds of STI diagnosis and having a risky sexual partner during third trimester, but not condom use. Whether discrimination was attributed to race, identifying as Black, or identifying as Latina did not moderate effects. This is the first investigation establishing a link between discrimination and STI diagnosis, not just risk behavior. It does so among a sample of at-risk, young, pregnant, women of color. Findings suggest implications for sexual risk during pregnancy and across the life span, and risks for the pregnancy and fetus. It is vital to reduce discrimination to eliminate disparities in HIV and STIs. Future research should continue examining the role of discrimination in sexual risk among different populations and work to uncover potential mechanisms. 2014 APA, all rights reserved

    This article offers an economic analysis of color-blind alternatives to conventional affirmative action policies in higher education, focusing on efficiency issues. When the distribution of applicants' traits is fixed (i.e., in the short-run) color blindness leads colleges to shift weight from academic traits that predict performance to social traits that proxy for race. Using data on matriculates at several selective colleges and universities, we estimate that the short-run efficiency cost o...

  6. Embedding Color Watermarks in Color Images

    Directory of Open Access Journals (Sweden)

    Wu Tung-Lin

    2003-01-01

    Full Text Available Robust watermarking with oblivious detection is essential to practical copyright protection of digital images. Effective exploitation of the characteristics of human visual perception to color stimuli helps to develop the watermarking scheme that fills the requirement. In this paper, an oblivious watermarking scheme that embeds color watermarks in color images is proposed. Through color gamut analysis and quantizer design, color watermarks are embedded by modifying quantization indices of color pixels without resulting in perceivable distortion. Only a small amount of information including the specification of color gamut, quantizer stepsize, and color tables is required to extract the watermark. Experimental results show that the proposed watermarking scheme is computationally simple and quite robust in face of various attacks such as cropping, low-pass filtering, white-noise addition, scaling, and JPEG compression with high compression ratios.

    Full Text Available BACKGROUND Pregnancy is a physiological status of a woman. Every organ is adapting in order to accept another human body. The main changes occur in the endocrine, immune, metabolic and vascular systems. The skin is no exception. Many skin changes during pregnancy are considered to be normal or physiological including striae gravidarum or melasma. These physiological skin changes are usually well tolerated by the pregnant woman. There is no balance between these systems, however, and abnormalities can appear. Immunologic status of the woman plays an important role in the manifestations exhibited in the skin. Alterations of the skin during pregnancy can be classified as physiologic skin changes, changes in pre-existing skin diseases and specific dermatoses of pregnancy. MATERIALS AND METHODS 200 pregnant women with skin manifestations attending Dermatology and Obstetric departments attached to Government General Hospital, Kurnool, were studied. 1. A detailed proforma was taken, which included: a. Detailed history including chief complaints related to skin. b. Onset in relation to duration of pregnancy. c. Complete general physical and systemic examination. d. Associated skin/medical disorders. 2. Investigations-CBP, CUE, RBS, LFT, HBsAg, VDRL, HIV 1 and 2 were done routinely. 3. KOH mount, saline mount and skin biopsy performed wherever required. Inclusion criteria- All pregnant women having skin lesions were included in the study irrespective of the duration of pregnancy and gravidity. Exclusion criteria- Pregnant women having any underlying medical diseases. All pregnant women attending antenatal OPD and those admitted into wards having symptoms related to skin and mucosa, at KIMS Hospital are studied. 1.

    Race is an independent factor in health disparity. We developed a training module to address race, racism, and health care. A group of 19 physicians participated in our training module. Anonymous survey results before and after the training were compared using a two-sample t-test. The awareness of racism and its impact on care increased in all participants. White participants showed a decrease in self-efficacy in caring for patients of color when compared to white patients. This training was successful in deconstructing white providers' previously held beliefs about race and racism. © 2015 Wiley Periodicals, Inc.

    One way teachers can disrupt inequities is by doing the work to foster discussions in which students talk about race--and racism--honestly together. Teachers also need to be ready to talk with students sensitively when the subject of race comes up spontaneously--in a student's work, connected to events outside school, or in response to a…

  18. Patent Races and Market Value

    DEFF Research Database (Denmark)

    Czarnitzki, Dirk; Hussinger, Katrin; Leten, Bart

    Patent races are models of strategic interactions between firms competing to develop an invention. The winning firm secures a patent, protecting the invention from imitation. This paper tests the assumption made about the reward structure in patent races, both in discrete and complex industries. We...... identify patent race winners using detailed information from the patent examination reports at the European Patent Office (EPO). Estimates of a market value equation featuring large, R&D-intensive U.S., European and Japanese firms, show that if firms win patent races, their market value increases...... significantly. We further show that the gain in market value is significantly larger for patent race winners in discrete industries than for firms in complex industries....

  20. Representing Color Ensembles.

    Science.gov (United States)

    Chetverikov, Andrey; Campana, Gianluca; Kristjánsson, Árni

    2017-10-01

    Colors are rarely uniform, yet little is known about how people represent color distributions. We introduce a new method for studying color ensembles based on intertrial learning in visual search. Participants looked for an oddly colored diamond among diamonds with colors taken from either uniform or Gaussian color distributions. On test trials, the targets had various distances in feature space from the mean of the preceding distractor color distribution. Targets on test trials therefore served as probes into probabilistic representations of distractor colors. Test-trial response times revealed a striking similarity between the physical distribution of colors and their internal representations. The results demonstrate that the visual system represents color ensembles in a more detailed way than previously thought, coding not only mean and variance but, most surprisingly, the actual shape (uniform or Gaussian) of the distribution of colors in the environment.

  5. Memory for color reactivates color processing region.

    Science.gov (United States)

    Slotnick, Scott D

    2009-11-25

    Memory is thought to be constructive in nature, where features processed in different cortical regions are synthesized during retrieval. In an effort to support this constructive memory framework, the present functional magnetic resonance imaging study assessed whether memory for color reactivated color processing regions. During encoding, participants were presented with colored and gray abstract shapes. During retrieval, old and new shapes were presented in gray and participants responded 'old-colored', 'old-gray', or 'new'. Within color perception regions, color memory related activity was observed in the left fusiform gyrus, adjacent to the collateral sulcus. A retinotopic mapping analysis indicated this activity occurred within color processing region V8. The present feature specific evidence provides compelling support for a constructive view of memory.

  6. Natural Colorants: Food Colorants from Natural Sources.

    Science.gov (United States)

    Sigurdson, Gregory T; Tang, Peipei; Giusti, M Mónica

    2017-02-28

    The color of food is often associated with the flavor, safety, and nutritional value of the product. Synthetic food colorants have been used because of their high stability and low cost. However, consumer perception and demand have driven the replacement of synthetic colorants with naturally derived alternatives. Natural pigment applications can be limited by lower stability, weaker tinctorial strength, interactions with food ingredients, and inability to match desired hues. Therefore, no single naturally derived colorant can serve as a universal alternative for a specified synthetic colorant in all applications. This review summarizes major environmental and biological sources for natural colorants as well as nature-identical counterparts. Chemical characteristics of prevalent pigments, including anthocyanins, carotenoids, betalains, and chlorophylls, are described. The possible applications and hues (warm, cool, and achromatic) of currently used natural pigments, such as anthocyanins as red and blue colorants, and possible future alternatives, such as purple violacein and red pyranoanthocyanins, are also discussed.

    In Mexico, 20% of the annual births are presented in women younger than 20 years old. Pregnancy in adolescents puts at risk mother and child health. This risk is major while the woman is younger, especially when the social and economic conditions are not favorable, which is decisive in later psychosocial development. It has been pointed out that the youths with low education, with minor academic and laboral expectations, with low self-esteem and assertiveness, tend to begin early their active sexual life, to use less frequently contraceptives, and in the case of younger women, to be pregnant, with the risk of abortion because they cannot to make the best decision. It is important to take into account the social context and the special characteristics of the family to understand situation of adolescent at risk of pregnancy.

  8. Race in California's prison fire camps for men: prison politics, space, and the racialization of everyday life.

    Science.gov (United States)

    Goodman, Philip

    2014-09-01

    The vast majority of social scientists agree that race is "socially constructed." Yet many scholars of punishment and prisons still treat race as static, self-evident categories. One result is that not enough is known about the production, meanings, and consequences of race as experienced by prisoners and those who guard and manage them. The author's research on California's prison fire camps uncovers the micro-level ways in which race is performed and imbued with meaning; he reveals how racial understandings color people and settings. One puzzle is that prisoners in California's fire camps will fight natural disasters side by side, sharing water and provisions, but separate into racial groups when in the camp itself. In part to answer this (and in part to develop better understandings of race and prisons more generally), the author unpacks the variegated nature of punishment and the spatialization of race and advocates for research that is faithful to the constructivist framework.

    Price, Trevor D

    2017-08-01

    Colors often appear to differ in arbitrary ways among related species. However, a fraction of color diversity may be explained because some signals are more easily perceived in one environment rather than another. Models show that not only signals but also the perception of signals should regularly evolve in response to different environments, whether these primarily involve detection of conspecifics or detection of predators and prey. Thus, a deeper understanding of how perception of color correlates with environmental attributes should help generate more predictive models of color divergence. Here, I briefly review our understanding of color vision in vertebrates. Then I focus on opsin spectral tuning and opsin expression, two traits involved in color perception that have become amenable to study. I ask how opsin tuning is correlated with ecological differences, notably the light environment, and how this potentially affects perception of conspecific colors. Although opsin tuning appears to evolve slowly, opsin expression levels are more evolutionarily labile but have been difficult to connect to color perception. The challenge going forward will be to identify how physiological differences involved in color vision, such as opsin expression levels, translate into perceptual differences, the selection pressures that have driven those differences, and ultimately how this may drive evolution of conspecific colors.

  11. Industrial Color Physics

    CERN Document Server

    Klein, Georg A

    2010-01-01

    This unique book starts with a short historical overview of the development of the theories of color vision and applications of industrial color physics. The three dominant factors producing color - light source, color sample, and observer - are described in detail. The standardized color spaces are shown and related color values are applied to characteristic color qualities of absorption as well as of effect colorants. The fundamentals of spectrometric and colorimetric measuring techniques together with specific applications are described. Theoretical models for radiative transfer in transparent, translucent, and opaque layers are detailed; the two, three, and multi-flux approximations are presented for the first time in a coherent formalism. These methods constitute the fundamentals not only for the important classical methods, but also modern methods of recipe prediction applicable to all known colorants. The text is supplied with 52 tables, more than 200 partially colored illustrations, an appendix, and a...

  12. Color: Physics and Perception

    Science.gov (United States)

    Gilbert, Pupa

    Unless we are colorblind, as soon as we look at something, we know what color it is. Simple, isn't it? No, not really. The color we see is rarely just determined by the physical color, that is, the wavelength of visible light associated with that color. Other factors, such as the illuminating light, or the brightness surrounding a certain color, affect our perception of that color. Most striking, and useful, is understanding how the retina and the brain work together to interpret the color we see, and how they can be fooled by additive color mixing, which makes it possible to have color screens and displays. I will show the physical origin of all these phenomena and give live demos as I explain how they work. Bring your own eyes!

  16. Race trouble: attending to race and racism in online interaction.

    Science.gov (United States)

    Durrheim, Kevin; Greener, Ross; Whitehead, Kevin A

    2015-03-01

    This article advocates the concept of race trouble as a way of synthesizing variation in racial discourse, and as a way of studying how social interaction and institutional life continue to be organized by conceptions of 'race' and 'racism'. Our analysis of an online discussion at a South African University about the defensibility of a characterization of (black) student protesters as 'savages' revealed a number of familiar strategies: participants avoided explicit racism, denied racism, and denied racism on behalf of others. However, the aim of this analysis was not to identify the 'real' racism, but to show how race and racism were used in the interaction to develop perspectives on transformation in the institution, to produce social division in the University, and to create ambivalently racialized and racializing subject positions. We demonstrate how, especially through uses of deracialized discourse, participants' actions were observably shaped by the potential ways in which others could hear 'race' and 'racism'. Race trouble thus became manifest through racial suggestion, allusion, innuendo, and implication. We conclude with a call to social psychologists to study the ways in which meanings of 'race' and 'racism' are forged and contested in relation to each other. © 2014 The British Psychological Society.

    Stephen Haywood

    Dear Muriel, Being an animal, you are probably more familiar with rats than most of us. Yet it seems to me that our Community (not just ATLAS) is stuck in a huge "rat race". I am somewhat mystified as to how we have got ourselves into this and I wonder whether you or your readers could explain this - I give my own observations below. In HEP and ATLAS specifically, we are all working long hours and we are all becoming exhausted. There are people at Point 1 who are working day and night, every day of the week; there are people writing software who send emails round the clock, including weekends. It is one thing to have bursts of activity which require us to put in some longer hours, but in ATLAS, the bursts last months or years. I have been on ATLAS 14 years and it has felt like one endless rush. Why do we do this? We are all highly motivated, we love our work and want to succeed individually and collectively. We are parts of various teams, and we do not want to let the side down. We worked hard at school an...

  19. Unplanned pregnancies in the United States.

    Science.gov (United States)

    Grimes, D A

    1986-03-01

    Unplanned pregnancies constitute an epidemic in the United States. Over 3 million unplanned pregnancies occur, and over 1.5 million induced abortions are performed each year. Women of minority races and those with less than 12 years of education are at high risk of having unwanted children. Fear of complications (not the complications themselves) is the most powerful deterrent to women's use of contraception. Much of this fear is due to bad press. Recent good news about contraception, such as protection against ovarian and endometrial cancer, protection against ectopic pregnancy, and absence of teratogenic effects, has not received appropriate media coverage. For healthy women younger than 35 years, failure to use fertility control is more dangerous than use of any method.

    Lora E Vess

    2016-11-01

    Full Text Available The rise of black consciousness through “Black Lives Matter” protests and recent events regarding police shootings of unarmed people of color have triggered a national dialogue on race, privilege, and discrimination. I structured my 400-level Race and Ethnicity course to build on the momentum of these conversations by incorporating a student-led race-centric research project whereby students learn and apply in-depth interview skills. Through this qualitative group project, students interviewed 31 members of the university community to investigate colorblindness, racial identity, privilege, racialized experiences, and institutional racism on their campus. In this article, I describe the project, and consider its strengths and limitations as a means of student learning about race, privilege, and discrimination in the U.S. today. I include student quotations gathered through final reflection papers to give voice to their experiences as well as a self-reflection of my experiences as part of this project, particularly as a white woman.

  3. PREDICTORS AND CONSEQUENCES OF ADOLESCENTS’ NORMS AGAINST TEENAGE PREGNANCY

    Science.gov (United States)

    Mollborn, Stefanie

    2011-01-01

    African American and Latino teenagers and communities are frequently assumed to have weaker norms against teenage pregnancy than whites. Despite their importance, adolescents’ norms about teenage pregnancy have not been measured or their correlates and consequences documented. This study examines individual-level and contextual variation in adolescents’ embarrassment at the prospect of a teenage pregnancy and its relationship with subsequent teenage pregnancy. Descriptive analyses find that norms vary by gender and individual- and neighborhood-level race, ethnicity, and socioeconomic status (SES). In multivariate analyses, neighborhood-level racial/ethnic associations with embarrassment are explained by neighborhood-level SES. Embarrassment is associated with a lower likelihood of subsequent teenage pregnancy but does not mediate racial, ethnic, or socioeconomic influences, underscoring the importance of both norms and structural factors for understanding teenage fertility.

  4. The differential effects of maternal age, race/ethnicity and insurance on neonatal intensive care unit admission rates

    Directory of Open Access Journals (Sweden)

    de Jongh Beatriz E

    2012-09-01

    Full Text Available Abstract Background Maternal race/ethnicity, age, and socioeconomic status (SES are important factors determining birth outcome. Previous studies have demonstrated that, teenagers, and mothers with advanced maternal age (AMA, and Black/Non-Hispanic race/ethnicity can independently increase the risk for a poor pregnancy outcome. Similarly, public insurance has been associated with suboptimal health outcomes. The interaction and impact on the risk of a pregnancy resulting in a NICU admission has not been studied. Our aim was, to analyze the simultaneous interactions of teen/advanced maternal age (AMA, race/ethnicity and socioeconomic status on the odds of NICU admission. Methods The Consortium of Safe Labor Database (subset of n = 167,160 live births was used to determine NICU admission and maternal factors: age, race/ethnicity, insurance, previous c-section, and gestational age. Results AMA mothers were more likely than teenaged mothers to have a pregnancy result in a NICU admission. Black/Non-Hispanic mothers with private insurance had increased odds for NICU admission. This is in contrast to the lower odds of NICU admission seen with Hispanic and White/Non-Hispanic pregnancies with private insurance. Conclusions Private insurance is protective against a pregnancy resulting in a NICU admission for Hispanic and White/Non-Hispanic mothers, but not for Black/Non-Hispanic mothers. The health disparity seen between Black and White/Non-Hispanics for the risk of NICU admission is most evident among pregnancies covered by private insurance. These study findings demonstrate that adverse pregnancy outcomes are mitigated differently across race, maternal age, and insurance status.

  5. Vasculitis and Pregnancy.

    Machen, Leah; Clowse, Megan E B

    2017-05-01

    Vasculitis is more often a disease of women beyond their reproductive years, leaving the challenges of pregnancy management difficult to study. Pregnancy complications, including pregnancy loss and preterm birth, are higher among women with all forms of vasculitis. It seems that controlling the disease before pregnancy may improve the chances of pregnancy success. Many medications used for vasculitis are considered low risk in pregnancy, including prednisone, colchicine, azathioprine, and tumor necrosis factor inhibitors. Cyclophosphamide, methotrexate, and mycophenolate mofetil should be avoided in pregnancy. Controlling disease with low-risk medications may allow women with vasculitis to have the pregnancies they desire. Copyright © 2017 Elsevier Inc. All rights reserved.

  9. Coloring mixed hypergraphs

    CERN Document Server

    Voloshin, Vitaly I

    2002-01-01

    The theory of graph coloring has existed for more than 150 years. Historically, graph coloring involved finding the minimum number of colors to be assigned to the vertices so that adjacent vertices would have different colors. From this modest beginning, the theory has become central in discrete mathematics with many contemporary generalizations and applications. Generalization of graph coloring-type problems to mixed hypergraphs brings many new dimensions to the theory of colorings. A main feature of this book is that in the case of hypergraphs, there exist problems on both the minimum and th

  10. Preferred skin color enhancement for photographic color reproduction

    Science.gov (United States)

    Zeng, Huanzhao; Luo, Ronnier

    2011-01-01

    Skin tones are the most important colors among the memory color category. Reproducing skin colors pleasingly is an important factor in photographic color reproduction. Moving skin colors toward their preferred skin color center improves the color preference of skin color reproduction. Several methods to morph skin colors to a smaller preferred skin color region has been reported in the past. In this paper, a new approach is proposed to further improve the result of skin color enhancement. An ellipsoid skin color model is applied to compute skin color probabilities for skin color detection and to determine a weight for skin color adjustment. Preferred skin color centers determined through psychophysical experiments were applied for color adjustment. Preferred skin color centers for dark, medium, and light skin colors are applied to adjust skin colors differently. Skin colors are morphed toward their preferred color centers. A special processing is applied to avoid contrast loss in highlight. A 3-D interpolation method is applied to fix a potential contouring problem and to improve color processing efficiency. An psychophysical experiment validates that the method of preferred skin color enhancement effectively identifies skin colors, improves the skin color preference, and does not objectionably affect preferred skin colors in original images.

  11. Auto white balance method using a pigmentation separation technique for human skin color

    Tanaka, Satomi; Kakinuma, Akihiro; Kamijo, Naohiro; Takahashi, Hiroshi; Tsumura, Norimichi

    2017-02-01

    The human visual system maintains the perception of colors of an object across various light sources. Similarly, current digital cameras feature an auto white balance function, which estimates the illuminant color and corrects the color of a photograph as if the photograph was taken under a certain light source. The main subject in a photograph is often a person's face, which could be used to estimate the illuminant color. However, such estimation is adversely affected by differences in facial colors among individuals. The present paper proposes an auto white balance algorithm based on a pigmentation separation method that separates the human skin color image into the components of melanin, hemoglobin and shading. Pigment densities have a uniform property within the same race that can be calculated from the components of melanin and hemoglobin in the face. We, thus, propose a method that uses the subject's facial color in an image and is unaffected by individual differences in facial color among Japanese people.

  12. Racial dialogues: challenges faculty of color face in the classroom.

    Sue, Derald Wing; Rivera, David P; Watkins, Nicole L; Kim, Rachel H; Kim, Suah; Williams, Chantea D

    2011-07-01

    Research on the experiences of faculty of color in predominantly White institutions (PWIs) suggests that they often experience the campus climate as invalidating, alienating, and hostile. Few studies, however, have actually focused on the classroom experiences of faculty of color when difficult racial dialogues occur. Using Consensually Qualitative Research, eight faculty of color were interviewed about their experiences in the classroom when racially tinged topics arose. Three major findings emerged. First, difficult racial dialogues were frequently instigated by the presence of racial microaggressions delivered toward students of color or the professor. Dialogues on race were made more difficult when the classrooms were diverse, when heated emotions arose, when there was a strong fear of self-disclosure, and when racial perspectives differed. Second, all faculty experienced an internal struggle between balancing their own values and beliefs with an attempt to remain objective. This conflict was often described as exhausting and energy-depleting. Third, faculty of color described both successful and unsuccessful strategies in facilitating difficult dialogues on race that arose in the course of their teaching. These findings have major implications for how PWIs can develop new programs, policies, and practices that will aid and support colleagues of color.

It is assumed that colored states have not been produced at present energies and only experimental tests which apply below the color threshold, when color is a ''hidden symmetry,'' are discussed. Some of these tests offer the possibility of distinguishing between quark models with fractional and integral quark charges. (auth)

    Krzysztof Wiktorowicz

    2015-01-01

    Full Text Available This paper presents the use of linear and nonlinear multivariable models as tools to support training process of race walkers. These models are calculated using data collected from race walkers’ training events and they are used to predict the result over a 3 km race based on training loads. The material consists of 122 training plans for 21 athletes. In order to choose the best model leave-one-out cross-validation method is used. The main contribution of the paper is to propose the nonlinear modifications for linear models in order to achieve smaller prediction error. It is shown that the best model is a modified LASSO regression with quadratic terms in the nonlinear part. This model has the smallest prediction error and simplified structure by eliminating some of the predictors.

    2018-01-01

    Full Text Available This article introduces a novel theoretical approach for understanding racial fluidity, emphasizing the social embeddedness of racial classifications. We propose that social ties affect racial perceptions through within-group micromechanisms, resulting in discrepancies between racial self-identifications and race as classified by others. We demonstrate this empirically on data from 12 Hungarian high school classes with one minority group (the Roma using stochastic actor-oriented models for the analysis of social network panel data. We find strong evidence for social influence: individuals tend to accept their peers' judgement about another student’s racial category; opinions of friends have a larger effect than those of nonfriends. Perceived social position also matters: those well-accepted among majority-race peers are likely to be classified as majority students themselves. We argue that similar analyses in other social contexts shall lead to a better understanding of race and interracial processes.

    A confocal color laser microscope which utilizes a three color laser light source (Red: He-Ne, Green: Ar, Blue: Ar) has been developed and is finding useful applications in the semiconductor field. The color laser microscope, when compared to a conventional microscope, offers superior color separation, higher resolution, and sharper contrast. Recently some new functions including a Focus Scan Memory, a Surface Profile Measurement System, a Critical Dimension Measurement system (CD) and an Optical Beam Induced Current Function (OBIC) have been developed for the color laser microscope. This paper will discuss these new features.

    Pre-pregnancy obesity has been associated with adverse birth outcomes. Poor essential fatty acid (EFA) and micronutrient status during pregnancy may contribute to these associations. We assessed the associations between pre-pregnancy BMI and nutritional patterns of maternal micronutrient and EFA status during mid-pregnancy. A cross-sectional analysis from a prospective cohort study. Women provided non-fasting blood samples at ≥ 20 weeks’ gestation that were assayed for red cell EFA; plasma folate, homocysteine and ascorbic acid; and serum retinol, 25-hydroxyvitamin D, a-tocopherol, soluble transferrin receptors and carotenoids. These nutritional biomarkers were employed in a factor analysis and three patterns were derived: EFA, Micronutrients and Carotenoids. The Antidepressant Use During Pregnancy Study, Pittsburgh, PA, USA. Pregnant women (n 129). After adjustment for parity, race/ethnicity and age, obese pregnant women were 3.0 (95% CI 1.1, 7.7) times more likely to be in the lowest tertile of the EFA pattern and 4.5 (95% CI 1.7, 12.3) times more likely to be in the lowest tertile of the Carotenoid pattern compared with their lean counterparts. We found no association between pre-pregnancy obesity and the Micronutrient pattern after confounder adjustment. Our results suggest that obese pregnant women have diminished EFA and carotenoid concentrations.

    Color is the most frequently studied feature in visual working memory (VWM). Oddly, much of this work de-emphasizes perception, instead making simplifying assumptions about the inputs served to memory. We question these assumptions in light of perception research, and we identify important points of contact between perception and working memory in the case of color. Better characterization of its perceptual inputs will be crucial for elucidating the structure and function of VWM. Copyright © 2014 Elsevier Ltd. All rights reserved.

These effects would be particularly evident for those individuals affected by the so called Meares-Irlen syndrome, i.e. who experience eyestrain and/or visual distortions – e.g. color, shape or movement illusions – while reading. This condition would interest the 12-14% of the general population and up to the 46% of the dyslexic population. Thus, colored overlays have been largely employed as a remedy for some aspects of the difficulties in reading experienced by dyslexic individuals, as fluency and speed. Despite the wide use of colored overlays, how they exert their effects has not been made clear yet. Also, according to some researchers, the results supporting the efficacy of colored overlays as a tool for helping readers are at least controversial. Furthermore, the very nature of the Meares-Irlen syndrome has been questioned. Here we provide a concise, critical review of the literature.

    Cervical abortion is a spontaneous abortion of an intrauterine pregnancy into the cervical canal where the abortus is retained by a closed external os, causing distension of the cervical canal. Cervical abortion should be distinguished from the cervical pregnancy. We present a case of cervical abortion diagnosed preoperatively by transvaginal sonography and color doppler imaging, and treated by dilatation and curettage. Charateristic transvaginal sonographic findings and identification of subtrophoblastic blood flow by color doppler imaging could allow differentiation of the cevical aborition from the cervical pregnancy

    Concern has been expressed in North Carolina that solid waste facilities may be disproportionately located in poor communities and in communities of color, that this represents an environmental injustice, and that solid waste facilities negatively impact the health of host communities. Our goal in this study was to conduct a statewide analysis of the location of solid waste facilities in relation to community race and wealth. We used census block groups to obtain racial and economic characteristics, and information on solid waste facilities was abstracted from solid waste facility permit records. We used logistic regression to compute prevalence odds ratios for 2003, and Cox regression to compute hazard ratios of facilities issued permits between 1990 and 2003. The adjusted prevalence odds of a solid waste facility was 2.8 times greater in block groups with > or = 50% people of color compared with block groups with or = 100,000 dollars. Among block groups that did not have a previously permitted solid waste facility, the adjusted hazard of a new permitted facility was 2.7 times higher in block groups with > or = 50% people of color compared with block groups with waste facilities present numerous public health concerns. In North Carolina solid waste facilities are disproportionately located in communities of color and low wealth. In the absence of action to promote environmental justice, the continued need for new facilities could exacerbate this environmental injustice.

  8. Representations of race and skin tone in medical textbook imagery.

    Louie, Patricia; Wilkes, Rima

    2018-04-01

    Although a large literature has documented racial inequities in health care delivery, there continues to be debate about the potential sources of these inequities. Preliminary research suggests that racial inequities are embedded in the curricular edification of physicians and patients. We investigate this hypothesis by considering whether the race and skin tone depicted in images in textbooks assigned at top medical schools reflects the diversity of the U.S. We analyzed 4146 images from Atlas of Human Anatomy, Bates' Guide to Physical Examination & History Taking, Clinically Oriented Anatomy, and Gray's Anatomy for Students by coding race (White, Black, and Person of Color) and skin tone (light, medium, and dark) at the textbook, chapter, and topic level. While the textbooks approximate the racial distribution of the U.S. population - 62.5% White, 20.4% Black, and 17.0% Person of Color - the skin tones represented - 74.5% light, 21% medium, and 4.5% dark - overrepresent light skin tone and underrepresent dark skin tone. There is also an absence of skin tone diversity at the chapter and topic level. Even though medical texts often have overall proportional racial representation this is not the case for skin tone. Furthermore, racial minorities are still often absent at the topic level. These omissions may provide one route through which bias enters medical treatment. Copyright © 2018.

    2013-01-01

    A persistent issue facing criminologists is the challenge of developing theoretical models that provide comprehensive explanations of the onset and persistence of criminality. One promising theory to develop over the last 30 years has been life-course theory. Using multivariate analysis of variance the main question posed in this research, do elements of social development shape the trajectory of persistent offending in a race-neutral fashion, or are the dynamics shaping life-course criminality unique for people of color, was examined. The results provide a number of useful insights into the relationship between race, life-course transition factors, and longitudinal patterns of criminality. PMID:23436952

    Objective To investigate the clinical value of transvaginal color Doppler ultrasound in the diagnosis and treatment of cesarean scar pregnancy (CSP). Methods Sonographic characteristics of 21 patients with CSP in the Third People's Hospital of Dongguan City from January 2009 to October 2014 were analyzed retrospectively, 21 cases were examined by transvaginal color Doppler ultrasound, and treated with puncture and injection of medicine under vaginal ultrasonography detection, transvaginal ultrasound manifestations of 21 cases were summarized, the lesion length to di-ameter, wide diameter, anterior uterine wall peripheral arterial resistance thickness and lesions with muscular segment index (resistive index, RI) before and after drug injection for the treatment of puncture were compared. Results 21 cas-es with CSP were divided into the following types pure gestational sac type (18 cases), and complete gestational sac were showed in anterior wall of the lower part of the incision of uterus intramural under ultrasond, yolk sac, embryo bud and original fetal heart beat were seen in gestational sac of 11 cases, yolk sac, embryo bud were seen in gestation-al sac of 3 cases, but no fetal heart beat, yolk sac were only seen in gestational sac of 2 cases but no embryo bud or fetal heart beat, gestational sac shrinkage, deformation were in 2 cases, and 3 cases were the mass type, and mixed e-chogenic mass were showed in the incision of the anterior wall of hypomere of the uterus, and uterine muscular layer boundary was not clear, the incision area muscle layer was humble, ditissimus blood flow signals were showed around the gestational sac or clumps under color Doppler ultrasond, nourishing vessels were from the incision of uterine mus-cular layer, blood flow signals were seen in the mass lesions of 3 cases, spectral Doppler showed a low speed and low resistance, the RI value was 0.32-0.56. Compared with before treatment, the length and width of CSP lesions in 21 pa

    A color recording unit was designed for output and control of digitized picture data within computer controlled reproduction and picture processing systems. In order to get a color proof picture of high quality similar to a color print, together with reduced time and material consumption, a photographic color film material was exposed pixelwise by modulated laser beams of three wavelengths for red, green and blue light. Components of different manufacturers for lasers, acousto-optic modulators and polygon mirrors were tested, also different recording methods as (continuous tone mode or screened mode and with a drum or flatbed recording principle). Besides the application for the graphic arts - the proof recorder CPR 403 with continuous tone color recording with a drum scanner - such a color hardcopy peripheral unit with large picture formats and high resolution can be used in medicine, communication, and satellite picture processing.

    Filament fused fabrication is the method of choice for printing 3D models at low cost, and is the de-facto standard for hobbyists, makers and schools. Unfortunately, filament printers cannot truly reproduce colored objects. The best current techniques rely on a form of dithering exploiting occlusion, that was only demonstrated for shades of two base colors and that behaves differently depending on surface slope. We explore a novel approach for 3D printing colored objects, capable of creating ...

    Aquilino, Mary Lober; Losch, Mary E

    2005-01-01

    To illustrate trends in unintended pregnancy over a 5-year period and to describe variations in desire for pregnancy at conception in relation to maternal age, race/ethnicity, income, and education. Data were collected as part of the Iowa Barriers to Prenatal Care Project, a large, multiyear study of new mothers. A brief questionnaire eliciting maternal experiences and behaviors during pregnancy was administered to new mothers in all Iowa hospitals providing maternity care following the birth of their baby. Sample sizes ranged from 16,714 to 19,421 over the 5 years included in this analysis (1997 to 2001), and response rates ranged from 44% to 53%. The study sample closely matched the overall statewide profile of women in this age group. In each of the 5 years, about one third of the mothers giving birth indicated that they did not intend to become pregnant at that time, and another 4% to 5% indicated that they did not want to be pregnant at that time or in the future. There were no substantive variations across years. Maternal age, race/ethnicity, income, and education were significantly related to intendedness of pregnancy. The findings underscore the continuing challenge of unintended pregnancy, despite recent national attention to this issue. All women of childbearing age should be considered at risk for unintended pregnancy. Additional work is needed to examine reasons, attitudes, and behaviors associated with unintended pregnancies and to determine the relative predictive strength of key demographic variables to improve interventions aimed at decreasing unintended pregnancy rates.

  1. Luminance contours can gate afterimage colors and "real" colors.

    Science.gov (United States)

    Anstis, Stuart; Vergeer, Mark; Van Lier, Rob

    2012-09-06

    It has long been known that colored images may elicit afterimages in complementary colors. We have already shown (Van Lier, Vergeer, & Anstis, 2009) that one and the same adapting image may result in different afterimage colors, depending on the test contours presented after the colored image. The color of the afterimage depends on two adapting colors, those both inside and outside the test. Here, we further explore this phenomenon and show that the color-contour interactions shown for afterimage colors also occur for "real" colors. We argue that similar mechanisms apply for both types of stimulation.

    Although bullying is a prevalent issue in the United States, limited research has explored the impact of school diversity on types of bullying behavior. This study explores the relationship between school diversity, student race, and bullying within the school context. The participants were African American and Caucasian middle school students (n = 4,581; 53.4% female). Among the participants, 89.4% were Caucasian and 10.6% were African American. The research questions examined the relationship between school diversity, student race and bullying behaviors, specifically race-based victimization. The findings suggested that Caucasian middle school students experience more bullying than African American students generally, and specifically when minorities in school settings. Caucasian students also experienced almost three times the amount of race-based victimization than African American students when school diversity was held constant. Interestingly, African American students experienced twice the amount of race-based victimization than Caucasian students when in settings with more students of color. The present study provides insight into bullying behaviors across different contexts for different races and highlights the need to further investigate interactions between personal and environmental factors on the bulling experiences of youth.

    2008-01-01

    Omental pregnancy is a rare form of ectopic pregnancy and can be seen primarily or secondary to a tubal pregnancy. A 25-yeal-old woman presented with abdominal distention with pain and anemia without vaginal bleeding. After a provisional diagnosis of ruptured ectopic pregnancy, laparotomy was performed. On surgical exploration, the bilateral tubes and ovaries were intact, however, an omental pregnancy was detected as the cause of hemoperitoneum. Partial omentectomy was performed. Although most cases are secondary, presented here is an additional case of primary omental pregnancy at 12 weeks according to Studdiford's criteria. Histological evidence of neovascularization into the supporting tissue confirmed our diagnosis. A primary omental pregnancy should always be considered as a possible explanation for severe hemoperitoneum in ectopic pregnancies presenting with acute abdomen and with intact adnexes on surgical exploration.

    1999-10-23

    International studies have yielded contradictory results on efficacy of a sodium-restricted diet during pregnancy in preventing and curing hypertension of pregnancy. In the Netherlands three studies have been performed to investigate the value of dietary sodium restriction in pregnancy; they concerned epidemiology, prevention and treatment. Midwives often prescribed this dietary intervention. Urinary sodium excretion was not related to blood pressure changes in pregnancy. Dietary sodium restriction from the third month of pregnancy onwards did not reduce the incidence of pregnancy-induced hypertension. Maternal side effects were a decreased intake of nutrients, decreased maternal weight gain, lowered plasma volume and stimulation of the renin-angiotensin-aldosterone system. A dietary sodium restriction in women with early symptoms of pregnancy-induced hypertension showed no therapeutic effect on blood pressure. There is no place for dietary sodium restriction in the prevention or treatment of hypertension in pregnancy.

  16. Time from cervical conization to pregnancy and preterm birth.

    Science.gov (United States)

    Himes, Katherine P; Simhan, Hyagriv N

    2007-02-01

    To estimate whether the time interval between cervical conization and subsequent pregnancy is associated with risk of preterm birth. Our study is a case control study nested in a retrospective cohort. Women who underwent colposcopic biopsy or conization with loop electrosurgical excision procedure, large loop excision of the transformation zone, or cold knife cone and subsequently delivered at our hospital were identified with electronic databases. Variables considered as possible confounders included maternal race, age, marital status, payor status, years of education, self-reported tobacco use, history of preterm delivery, and dimensions of cone specimen. Conization was not associated with preterm birth or any subtypes of preterm birth. Among women who underwent conization, those with a subsequent preterm birth had a shorter conization-to-pregnancy interval (337 days) than women with a subsequent term birth (581 days) (P=.004). The association between short conization-to-pregnancy interval and preterm birth remained significant when controlling for confounders including race and cone dimensions. The effect of short conization-to-pregnancy interval on subsequent preterm birth was more persistent among African Americans when compared with white women. Women with a short conization-to-pregnancy interval are at increased risk for preterm birth. Women of reproductive age who must have a conization procedure can be counseled that conceiving within 2 to 3 months of the procedure may be associated with an increased risk of preterm birth. II.

  18. Chaotic evolution of arms races

    Science.gov (United States)

    Tomochi, Masaki; Kono, Mitsuo

    1998-12-01

    A new set of model equations is proposed to describe the evolution of the arms race, by extending Richardson's model with special emphases that (1) power dependent defensive reaction or historical enmity could be a motive force to promote armaments, (2) a deterrent would suppress the growth of armaments, and (3) the defense reaction of one nation against the other nation depends nonlinearly on the difference in armaments between two. The set of equations is numerically solved to exhibit stationary, periodic, and chaotic behavior depending on the combinations of parameters involved. The chaotic evolution is realized when the economic situation of each country involved in the arms race is quite different, which is often observed in the real world.

  19. The spectre of race in American medicine.

    Science.gov (United States)

    Fofana, Mariam O

    2013-12-01

    Controversies and debates surrounding race have long been a fixture in American medicine. In the past, the biological concept of race-the idea that race is biologically determined and meaningful-has served to justify the institution of slavery and the conduct of unethical research trials. Although these days may seem far behind, contemporary debates over the race-specific approval of drugs and the significance of genetic differences are evidence that race still yields tremendous influence on medical research and clinical practice. In many ways, the use of race in medicine today reflects the internalisation of racial hierarchies borne out of the history of slavery and state-mandated segregation, and there is still much uncertainty over its benefits and harms. Although using race in research can help elucidate disparities, the reflexive use of race as a variable runs the risk of reifying the biological concept of race and blinding researchers to important underlying factors such as socioeconomic status. Similarly, in clinical practice, the use of race in assessing a patient's risk of certain conditions (eg, sickle cell) turns harmful when the heuristic becomes a rule. Through selected historical and contemporary examples, I aim to show how the biological concept of race that gave rise to past abuses remains alive and harmful, and propose changes in medical education as a potential solution. By learning from the past, today's physicians will be better armed to discern-and correct-the ways in which contemporary medicine perpetuates historical injustices.

  20. Vitamin D deficiency in early pregnancy.

    Directory of Open Access Journals (Sweden)

    Shannon K Flood-Nichols

    Full Text Available Vitamin D deficiency is a common problem in reproductive-aged women in the United States. The effect of vitamin D deficiency in pregnancy is unknown, but has been associated with adverse pregnancy outcomes. The objective of this study was to analyze the relationship between vitamin D deficiency in the first trimester and subsequent clinical outcomes.This is a retrospective cohort study. Plasma was collected in the first trimester from 310 nulliparous women with singleton gestations without significant medical problems. Competitive enzymatic vitamin D assays were performed on banked plasma specimens and pregnancy outcomes were collected after delivery. Logistic regression was performed on patients stratified by plasma vitamin D concentration and the following combined clinical outcomes: preeclampsia, preterm delivery, intrauterine growth restriction, gestational diabetes, and spontaneous abortion.Vitamin D concentrations were obtained from 235 patients (mean age 24.3 years, range 18-40 years. Seventy percent of our study population was vitamin D insufficient with a serum concentration less than 30 ng/mL (mean serum concentration 27.6 ng/mL, range 13-71.6 ng/mL. Logistic regression was performed adjusting for age, race, body mass index, tobacco use, and time of year. Adverse pregnancy outcomes included preeclampsia, growth restriction, preterm delivery, gestational diabetes, and spontaneous abortion. There was no association between vitamin D deficiency and composite adverse pregnancy outcomes with an adjusted odds ratio of 1.01 (p value 0.738, 95% confidence intervals 0.961-1.057.Vitamin D deficiency did not associate with adverse pregnancy outcomes in this study population. However, the high percentage of affected individuals highlights the prevalence of vitamin D deficiency in young, reproductive-aged women.

  3. Perceptions of racial confrontation: the role of color blindness and comment ambiguity.

    Science.gov (United States)

    Zou, Linda X; Dickter, Cheryl L

    2013-01-01

    Because of its emphasis on diminishing race and avoiding racial discourse, color-blind racial ideology has been suggested to have negative consequences for modern day race relations. The current research examined the influence of color blindness and the ambiguity of a prejudiced remark on perceptions of a racial minority group member who confronts the remark. One hundred thirteen White participants responded to a vignette depicting a White character making a prejudiced comment of variable ambiguity, after which a Black target character confronted the comment. Results demonstrated that the target confronter was perceived more negatively and as responding less appropriately by participants high in color blindness, and that this effect was particularly pronounced when participants responded to the ambiguous comment. Implications for the ways in which color blindness, as an accepted norm that is endorsed across legal and educational settings, can facilitate Whites' complicity in racial inequality are discussed.

    Wheeler, Sarahn; Maxson, Pamela; Truong, Tracy; Swamy, Geeta

    2018-03-29

    Objectives Studies examining risk factors for preterm birth (PTB) such as psychosocial stress are often focused on women with a history of PTB; however, most preterm babies are born to women with no history of preterm birth. Our objective was to determine if the relationship between psychosocial stress and PTB is altered by parity. Non-Hispanic black (NHB) women have increased psychosocial stress and PTB; therefore, we further aimed to determine if race alters the relationship between psychosocial stress, parity, and PTB. Methods We performed a secondary analysis of the Healthy Pregnancy, Healthy Baby Study comparing pregnant women who were primiparous (first pregnancy), multiparous with history of preterm birth, or multiparous with history of term birth. Perceived stress, perceived racism, interpersonal support, John Henryism and self-efficacy were measured using validated instruments. Logistic regression was used to model the effect of psychosocial stress on PTB stratified by parity and race. Results The analysis entire cohort included 1606 subjects, 426 were primiparous, 268 had a history of presterm birth, and 912 had a history of term birth. In women with a history of term birth, higher self-efficacy was associated with lower odds of spontaneous PTB, and this association was amplified in NHB women. In women with a history of spontaneous PTB, John Henryism Active Coping was associated with lower odds of spontaneous PTB in the index pregnancy. Conclusions for Practice The relationship between psychosocial stress and PTB may be mediated by parity and race.

    Liver diseases in pregnancy may be categorized into liver disorders that occur only in the setting of pregnancy and liver diseases that occur coincidentally with pregnancy. Hyperemesis gravidarum, preeclampsia/eclampsia, syndrome of hemolysis, elevated liver tests and low platelets (HELLP), acute fatty liver of pregnancy, and intrahepatic cholestasis of pregnancy are pregnancy-specific disorders that may cause elevations in liver tests and hepatic dysfunction. Chronic liver diseases, including cholestatic liver disease, autoimmune hepatitis, Wilson disease, and viral hepatitis may also be seen in pregnancy. Management of liver disease in pregnancy requires collaboration between obstetricians and gastroenterologists/hepatologists. Treatment of pregnancy-specific liver disorders usually involves delivery of the fetus and supportive care, whereas management of chronic liver disease in pregnancy is directed toward optimizing control of the liver disorder. Cirrhosis in the setting of pregnancy is less commonly observed but offers unique challenges for patients and practitioners. This article reviews the epidemiology, pathophysiology, diagnosis, and management of liver diseases seen in pregnancy.

  3. Image color reduction method for color-defective observers using a color palette composed of 20 particular colors

    Sakamoto, Takashi

    2015-01-01

    This study describes a color enhancement method that uses a color palette especially designed for protan and deutan defects, commonly known as red-green color blindness. The proposed color reduction method is based on a simple color mapping. Complicated computation and image processing are not required by using the proposed method, and the method can replace protan and deutan confusion (p/d-confusion) colors with protan and deutan safe (p/d-safe) colors. Color palettes for protan and deutan defects proposed by previous studies are composed of few p/d-safe colors. Thus, the colors contained in these palettes are insufficient for replacing colors in photographs. Recently, Ito et al. proposed a p/dsafe color palette composed of 20 particular colors. The author demonstrated that their p/d-safe color palette could be applied to image color reduction in photographs as a means to replace p/d-confusion colors. This study describes the results of the proposed color reduction in photographs that include typical p/d-confusion colors, which can be replaced. After the reduction process is completed, color-defective observers can distinguish these confusion colors.

    Full Text Available On color constancy, we showed that brighter surrounding colors had greater influence than dim colors (Uchikawa, Kitazawa, MacLeod, Fukuda, 2010 APCV. Increasing luminance of a stimulus causes the change in appearance from the surface-color to the illuminant-color mode. However it is unknown whether the visual system considers such color appearance mode of surrounding colors to achieve color constancy. We investigated the influence of surrounding colors that appeared illuminant on color constancy. The stimulus was composed of a central test stimulus and surrounding six colors: bright and dim red, green and blue. The observers adjusted the chromaticity of the test stimulus to be appeared as an achromatic surface. The luminance balance of three bright surrounding colors was equalized with that of the optimal colors in three illuminant conditions, then, the luminance of one of the three bright colors was varied in the range beyond the critical luminance of color appearance mode transition. The results showed that increasing luminance of a bright surrounding color shifted the observers' achromatic setting toward its chromaticity, but this effect diminished for the surrounding color in the illuminant-color mode. These results suggest that the visual system considers color appearance mode of surrounding colors to accomplish color constancy.

  6. Color quarks and octonions

    International Nuclear Information System (INIS)

    Guersey, F.

    1974-01-01

    A mathematical framework based on octonions is developed for the description of the color quark scheme in which quarks are unobservable, the color SU(3) is exact, and only color singlets correspond to observable hadrons. The fictitious Hilbert space in which quarks operate is taken to be a space of vectors with octonion components. This space admits as a gauge group an exact SU(3) identified with the color SU/sub C/(3). Because of the nonassociativity of the underlying algebra, nonsinglet representations of SU/sub C/(3) are unobservable, while the subspace of color singlets satisfies associativity along with conditions for observability. Octonion quark fields satisfy the commutation relations of parafermions of order 3, leading to the correct SU(6) multiplets for hadrons. (U.S.)

    Sexual violence against children and adolescents is a serious threat to the rights and full health of this age group. This study aims to describe the characteristics of mothers aged up to 13, and analyze the profile of cases of notified rape in this age range and repercussions of this violence during pregnancy and childbirth. It is a comparative study of the characteristics of gestation and childbirth of girls aged up to 13 who have had children, without or with notification of rape, in the Violence & Accidents Vigilance (VIVA) System of the Brazilian Case Registry Database (Sistema de Informação de Agravos de Notificação - SINAN). A significant percentage (67.5%) of the girls aged up to 13 with children were of the black race/color category. There was repeated violence in 58.2% of cases. The notified rape victims have a higher percentage of birth by cesarean section, late onset and a lower number of prenatal consultations; and their babies had lower birthweight and lower 1-minute Apgar scores than mothers without rape notification. Rape of children and adolescents is an important risk factor that has repercussions during pregnancy, and complications in delivery and childbirth.

    2013-01-01

    A color evaluation approach for computer-generated color rainbow holography (CGCRH) is presented. Firstly, the relationship between color quantities of a computer display and a color computer-generated holography (CCGH) colorimetric system is discussed based on color matching theory. An isochromatic transfer relationship of color quantity and amplitude of object light field is proposed. Secondly, the color reproduction mechanism and factors leading to the color difference between the color object and the holographic image that is reconstructed by CGCRH are analyzed in detail. A quantitative color calculation method for the holographic image reconstructed by CGCRH is given. Finally, general color samples are selected as numerical calculation test targets and the color differences between holographic images and test targets are calculated based on our proposed method.

    Full Text Available We present two cases of carnitine deficiency in pregnancy. In our first case, systematic screening revealed L-carnitine deficiency in the first born of an asymptomatic mother. In the course of her second pregnancy, maternal carnitine levels showed a deficiency as well. In a second case, a mother known with carnitine deficiency under supplementation was followed throughout her pregnancy. Both pregnancies had an uneventful outcome. Because carnitine deficiency can have serious complications, supplementation with carnitine is advised. This supplementation should be continued throughout pregnancy according to plasma concentrations.

    Full Text Available Juvenile dermatomyositis has variable clinical presentations both in and outside of pregnancy. A literature review indicated that optimal maternal and fetal outcomes can be anticipated when the pregnancy is undertaken while the disease is in remission. Poorer outcomes are associated with flare-up of the disease in early pregnancy compared with exacerbation in the second or third trimester, when fetal prognosis is usually good. We present a case of JDM in pregnancy with disease exacerbation late in pregnancy and review of the relevant literature.

    Routine exercise should be recommended to healthy pregnant women after consultation with an obstetric provider. Even pregnant women who have not been exercising regularly can gradually increase their exercise during pregnancy. Regular exercise during pregnancy promotes overall wellness and helps maintain appropriate gestational weight gain and appropriate fetal weight gain. Exercise in pregnancy may also reduce hypertensive disorders of pregnancy and gestational diabetes, and may be associated with shorter first stage of labor and decreased risk for cesarean section. Exercise in pregnancy is safe for pregnant women and their fetuses and can have multiple health benefits. Copyright © 2017 Elsevier Inc. All rights reserved.

    Hyperthyroidism is a rare complication of molar pregnancy. We report a 39-year-old woman who presented a thyrotoxic syndrome accompanying a molar pregnancy. Serum thyroid hormones were elevated and returned to normal level after uterine evacuation of a molar pregnancy. The authors detail the role of thyroid stimulating property of human gonadotropin chorionic hormone and its structural changes during the gestational trophoblastic diseases. These changes give the latter the thyroid stimulating properties and signs of hyperthyroidism. Molar pregnancy may be a cause of hyperthyroidism. The diagnosis of molar pregnancy should be a mention to thyrotoxicosique syndrome in a woman of childbearing age. Copyright © 2013. Published by Elsevier SAS.

  14. Racial Geographies, Imperial Transitions: Property Ownership and Race Relations in Cienfuegos, Cuba, 1894–1899

    Directory of Open Access Journals (Sweden)

    Bonnie Lucero

    2011-12-01

    Full Text Available This article explores race relations in the provincial city of Cienfuegos, Cuba, during a time of immense political change from 1894 to 1899. In those five years, Cuba was transformed from a Spanish colony struggling for independence to an occupied territory of the United States. This political transformation brought into direct confrontation two models of race relations: one Spanish, characterized by racial integration, and the other American, renowned for Jim Crow segregation. This essay examines the lived significance of this political transformation through interracial property transactions recorded in the notarial protocols of Cienfuegos. The findings suggest that the final war of independence provided opportunities for Afro-descendants to purchase prime properties within the official city bounds. Yet, with US intervention in 1898, a subtle but increasing marginalization of men and women of color from the market in urban property is evident. Lucero contends that this marginalization reflects a shift in race relations due to the American imperial presence.

  15. Diabetes insipidus during pregnancy.

    Ananthakrishnan, Sonia

    2016-03-01

    Diabetes insipidus (DI) in pregnancy is a heterogeneous syndrome, most classically presenting with polyuria and polydipsia that can complicate approximately 1 in 30,000 pregnancies. The presentation can involve exacerbation of central or nephrogenic DI during pregnancy, which may have been either overt or subclinical prior to pregnancy. Women without preexisting DI can also be affected by the actions of placental vasopressinase which increases in activity between the 4th and 38th weeks of gestation, leading to accelerated metabolism of AVP and causing a transient form of DI of pregnancy. This type of DI may be associated with certain complications during pregnancy and delivery, such as preeclampsia. Management of DI of pregnancy depends on the pathophysiology of the disease; forms of DI that lack AVP can be treated with desmopressin (DDAVP), while forms of DI that involve resistance to AVP require evaluation of the underlying causes.

    2016-06-01

    Diabetes insipidus (DI) is a rare complication of pregnancy. It is usually transient, being due to increased placental production of vasopressinase that inactivates circulating vasopressin. Gestational, transient DI occurs late in pregnancy and disappears few days after delivery. Acquired central DI can also occur during pregnancy, for example in a patient with hypophysitis or neuroinfundibulitis during late pregnancy or postpartum. Finally, pre-existing central or nephrogenic DI may occasionally be unmasked by pregnancy. Treatment with dDAVP (desmopressin, Minirin(®)) is very effective on transient DI of pregnancy and also on pre-existing or acquired central DI. Contrary to vasopressin, dDAVP is not degraded by vasopressinase. Nephrogenic DI is insensitive to dDAVP and is therefore more difficult to treat during pregnancy if fluid intake needs to be restricted. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Higher concentrations of certain phthalate metabolites are associated with adverse reproductive and pregnancy outcomes, as well as poor infant/child health outcomes. In non-pregnant populations, phthalate metabolite concentrations vary by race/ethnicity. Few studies have documented racial/ethnic differences between phthalate metabolite concentrations at multiple time points across the full-course of pregnancy. The objective of the study was to characterize the change in phthalate metabolite concentrations by race/ethnicity across multiple pregnancy time points. Women were participants in a prospectively collected pregnancy cohort who delivered at term (≥37 weeks) and had available urinary phthalate metabolite concentrations for ≥3 time points across full-term pregnancies (n=350 women). We assessed urinary concentrations of eight phthalate metabolites that were log-transformed and specific gravity-adjusted. We evaluated the potential racial/ethnic differences in phthalate metabolite concentrations at baseline (median 10 weeks gestation) using ANOVA and across pregnancy using linear mixed models to calculate the percent change and 95% confidence intervals adjusted for sociodemographic and lifestyle factors. Almost 30% of the population were non-Hispanic black or Hispanic. With the exception of mono-(3-carboxypropyl) (MCPP) and di-ethylhexyl phthalate (DEHP) metabolites, baseline levels of phthalate metabolites were significantly higher in non-whites (Pethnicity, mono-ethyl phthalate (MEP) and MCPP had significant percent changes across pregnancy. MEP was higher in Hispanics at baseline and decreased in mid-pregnancy but increased in late pregnancy for non-Hispanic blacks. MCPP was substantially higher in non-Hispanic blacks at baseline but decreased later in pregnancy. Across pregnancy, non-Hispanic black and Hispanic women had higher concentrations of certain phthalate metabolites. These differences may have implications for racial/ethnic differences in adverse

    For centuries, the concept of race, a uniquely pervasive social construct, has often complicated dialogue and interactions between groups of people. This study assessed perceptions and attitudes of faculty and trainees with varied racial backgrounds within graduate medical and psychology programs. Self-reported responses addressed potential barriers and facilitating factors required for meaningful conversations about race. A brief 18-question survey was developed and administered electronically to three professional and academic Listservs within a large metropolitan city in northeast United States. Quantitative and qualitative analysis were conducted using SPSS Statistical Software and Text analyzer. Results revealed that among participants (N = 57) a majority experienced cross-racial supervision, and more than half indicated engaging in conversations about race within supervision. Respondents endorsed lack of comfort and lack of opportunity/time as significant barriers to discussing race within supervision. When race-related dialogues occurred, a majority of supervisees and supervisors found it beneficial. Most Supervisors of Color(a) actively initiated these conversations in supervision, while White supervisees endorsed the least benefit from these conversations. Contrary to our expectations, few respondents endorsed limited training as a barrier. The current study revealed cross-racial dialogues about race may be occurring frequently in supervisory relationships. Supervisees of Color reported benefiting from these dialogues, in contrast to their White counterparts, who endorsed the least benefit. Lack of comfort in supervisory relationships appears to be a significant barrier to having these conversations. Therefore, it is important for supervisors to create supervisory relationships emphasizing safety and comfort. Directions for future research are discussed. © The Author(s) 2016.

    The biological basis of the commonality in color lexicons across languages has been hotly debated for decades. Prior evidence that infants categorize color could provide support for the hypothesis that color categorization systems are not purely constructed by communication and culture. Here, we investigate the relationship between infants’ categorization of color and the commonality across color lexicons, and the potential biological origin of infant color categories. We systematically mappe...

    1999-12-15

    This report presents key findings from a comprehensive report on pregnancies and pregnancy rates for U.S. women. The study incorporates birth, abortion, and fetal loss data to compile national estimates of pregnancy rates according to a variety of characteristics including age, race, Hispanic origin, and marital status. Summary data are presented for 1976-96. Data from the National Survey of Family Growth (NSFG) are used to show information on sexual activity and contraceptive practices, as well as women's reports of pregnancy intentions. Tabular and graphic data on pregnancy rates by demographic characteristics are presented and interpreted. Birth data are from the birth registration system for all births registered in the United States and reported by State health departments to NCHS; abortion data are from The Alan Guttmacher Institute (AGI) and the National Center for Chronic Disease Prevention and Health Promotion, Centers for Disease Control and Prevention (CDC); and fetal loss data are from pregnancy history information collected in the NSFG. In 1996 an estimated 6.24 million pregnancies resulted in 3.89 million live births, 1.37 million induced abortions, and 0.98 million fetal losses. The pregnancy rate in 1996 was 104.7 pregnancies per 1,000 women aged 15-44 years, 9 percent lower than in 1990 (115.6), and the lowest recorded since 1976 (102.7). Since 1990 rates have dropped 8 percent for live births, 16 percent for induced abortions, and 4 percent for fetal losses. The teenage pregnancy rate has declined considerably in the 1990's, falling 15 percent from its 1991 high of 116.5 per 1,000 women aged 15-19 to 98.7 in 1996. Among the factors accounting for this decline are decreased sexual activity, increases in condom use, and the adoption of the injectable and implant contraceptives.

    The diagnosis of skin diseases relies on several clinical signs, among which color is of paramount importance. In this review, we consider certain clinical presentations of both eczematous and noneczematous contact dermatitis in which color plays a peculiar role orientating toward the right diagnosis. The conditions that will be discussed include specific clinical-morphologic subtypes of eczematous contact dermatitis, primary melanocytic, and nonmelanocytic contact hyperchromia, black dermographism, contact chemical leukoderma, and others. Based on the physical, chemical, and biologic factors underlying a healthy skin color, the various skin shades drawing a disease picture are thoroughly debated, stressing their etiopathogenic origins and histopathologic aspects.

    Stevens, P E

    1998-01-01

    Abstract In this feminist narrative study, lesbians of color gave testimony to the effects of prejudice in face-to-face health care interactions. A major objective was to involve participants from a broad range of ethnic/racial backgrounds and socio-economic circumstances in open-ended interviews about their experiences receiving health care. Half of the 45 women in the sample were lesbians of color: 20% (9) African American, 18% (8) Latina, 11% (5) Asian/Pacific Islander, and 2% (1) Native American. Results suggest that if we wish to improve access to and quality of health services, those in the health care field must address race, class, gender, and sexual orientation prejudice in health care interactions, acknowledging the role discriminatory behavior plays in diminishing the availability of health care for lesbians of color.

  10. Arms races between and within species.

    Science.gov (United States)

    Dawkins, R; Krebs, J R

    1979-09-21

    An adaptation in one lineage (e.g. predators) may change the selection pressure on another lineage (e.g. prey), giving rise to a counter-adaptation. If this occurs reciprocally, an unstable runaway escalation or 'arms race' may result. We discuss various factors which might give one side an advantage in an arms race. For example, a lineage under strong selection may out-evolve a weakly selected one (' the life-dinner principle'). We then classify arms races in two independent ways. They may be symmetric or asymmetric, and they may be interspecific or intraspecific. Our example of an asymmetric interspecific arms race is that between brood parasites and their hosts. The arms race concept may help to reduce the mystery of why cuckoo hosts are so good at detecting cuckoo eggs, but so bad at detecting cuckoo nestlings. The evolutionary contest between queen and worker ants over relative parental investment is a good example of an intraspecific asymmetric arms race. Such cases raise special problems because the participants share the same gene pool. Interspecific symmetric arms races are unlikely to be important, because competitors tend to diverge rather than escalate competitive adaptations. Intraspecific symmetric arms races, exemplified by adaptations for male-male competition, may underlie Cope's Rule and even the extinction of lineages. Finally we consider ways in which arms races can end. One lineage may drive the other to extinction; one may reach an optimum, thereby preventing the other from doing so; a particularly interesting possibility, exemplified by flower-bee coevolution, is that both sides may reach a mutual local optimum; lastly, arms races may have no stable and but may cycle continuously. We do not wish necessarily to suggest that all, or even most, evolutionary change results from arms races, but we do suggest that the arms race concept may help to resolve three long-standing questions in evolutionary theory.

    We review the progress made during the last thirty years on ground effect aerodynamics associated with race cars, in particular open wheel race cars. Ground effect aerodynamics of race cars is concerned with generating downforce, principally via low pressure on the surfaces nearest to the ground. The “ground effected” parts of an open wheeled car's aerodynamics are the most aerodynamically efficient and contribute less drag than that associated with, for example, an upper rear wing.

  12. Teen pregnancy: an update.

    2014-10-01

    To provide clinicians with a review of recent research and clinically applicable tools regarding teen pregnancy. Teen pregnancy rates have declined but still remain a significant problem in the USA. Teen pregnancy prevention was identified by Centers for Disease Control and Prevention as one of its top six priorities, which is increasing research and intervention data. Long-acting contraceptive methods are acceptable to teens and have been shown to reduce teen birth rates. Pregnant teens need special attention to counseling on pregnancy options and reducing risk during pregnancy with regular prenatal care. Postpartum teens should be encouraged and supported to breastfeed, monitored for depression, and have access to reliable contraception to avoid repeat undesired pregnancy. This review highlights important issues for all providers caring for female adolescents and those who may encounter teen pregnancy. Foremost prevention of teen pregnancy by comprehensive sexual education and access to contraception is the priority. Educating patients and healthcare providers about safety and efficacy of long-acting reversible contraception is a good step to reducing undesired teen pregnancies. Rates of postpartum depression are greater in adolescents than in adults, and adolescent mothers need to be screened and monitored for depression. Strategies to avoid another undesired pregnancy shortly after delivery should be implemented.

  7. Physics of structural colors

    International Nuclear Information System (INIS)

    Kinoshita, S; Yoshioka, S; Miyazaki, J

    2008-01-01

    In recent years, structural colors have attracted great attention in a wide variety of research fields. This is because they are originated from complex interaction between light and sophisticated nanostructures generated in the natural world. In addition, their inherent regular structures are one of the most conspicuous examples of non-equilibrium order formation. Structural colors are deeply connected with recent rapidly growing fields of photonics and have been extensively studied to clarify their peculiar optical phenomena. Their mechanisms are, in principle, of a purely physical origin, which differs considerably from the ordinary coloration mechanisms such as in pigments, dyes and metals, where the colors are produced by virtue of the energy consumption of light. It is generally recognized that structural colors are mainly based on several elementary optical processes including thin-layer interference, diffraction grating, light scattering, photonic crystals and so on. However, in nature, these processes are somehow mixed together to produce complex optical phenomena. In many cases, they are combined with the irregularity of the structure to produce the diffusive nature of the reflected light, while in some cases they are accompanied by large-scale structures to generate the macroscopic effect on the coloration. Further, it is well known that structural colors cooperate with pigmentary colors to enhance or to reduce the brilliancy and to produce special effects. Thus, structure-based optical phenomena in nature appear to be quite multi-functional, the variety of which is far beyond our understanding. In this article, we overview these phenomena appearing particularly in the diversity of the animal world, to shed light on this rapidly developing research field

  8. Color Laser Microscope

    Science.gov (United States)

    Awamura, D.; Ode, T.; Yonezawa, M.

    1987-04-01

    A color laser microscope utilizing a new color laser imaging system has been developed for the visual inspection of semiconductors. The light source, produced by three lasers (Red; He-Ne, Green; Ar, Blue; He-Cd), is deflected horizontally by an AOD (Acoustic Optical Deflector) and vertically by a vibration mirror. The laser beam is focused in a small spot which is scanned over the sample at high speed. The light reflected back from the sample is reformed to contain linear information by returning to the original vibration mirror. The linear light is guided to the CCD image sensor where it is converted into a video signal. Individual CCD image sensors are used for each of the three R, G, or B color image signals. The confocal optical system with its laser light source yields a color TV monitor image with no flaring and a much sharper resolution than that of the conventional optical microscope. The AOD makes possible a high speed laser scan and a NTSC or PAL TV video signal is produced in real time without any video memory. Since the light source is composed of R, G, and B laser beams, color separation superior to that of white light illumination is achieved. Because of the photometric linearity of the image detector, the R, G, and B outputs of the system are most suitably used for hue analysis. The CCD linear image sensors in the optical system produce no geometrical distortion, and good color registration is available principally. The output signal can be used for high accuracy line width measuring. The many features of the color laser microscope make it ideally suited for the visual inspection of semiconductor processing. A number of these systems have already been installed in such a capacity. The Color Laser Microscope can also be a very useful tool for the fields of material engineering and biotechnology.

  14. Color planner for designers based on color emotions

    Science.gov (United States)

    Cheng, Ka-Man; Xin, John H.; Taylor, Gail

    2002-06-01

    During the color perception process, an associated feeling or emotion is induced in our brains, and this kind of emotion is termed as 'color emotion.' The researchers in the field of color emotions have put many efforts in quantifying color emotions with the standard color specifications and evaluating the influence of hue, lightness and chroma to the color emotions of human beings. In this study, a color planner was derived according to these findings so that the correlation of color emotions and standard color specifications was clearly indicated. Since people of different nationalities usually have different color emotions as different cultural and traditional backgrounds, the subjects in this study were all native Hong Kong Chinese and the color emotion words were all written in Chinese language in the visual assessments. Through the color planner, the designers from different areas, no matter fashion, graphic, interior or web site etc., can select suitable colors for inducing target color emotions to the customers or product-users since different colors convey different meanings to them. In addition, the designers can enhance the functionality and increase the attractiveness of their designed products by selecting suitable colors.

  15. The Trojan Color Conundrum

    Science.gov (United States)

    Jewitt, David

    2018-02-01

    The Trojan asteroids of Jupiter and Neptune are likely to have been captured from original heliocentric orbits in the dynamically excited (“hot”) population of the Kuiper Belt. However, it has long been known that the optical color distributions of the Jovian Trojans and the hot population are not alike. This difference has been reconciled with the capture hypothesis by assuming that the Trojans were resurfaced (for example, by sublimation of near-surface volatiles) upon inward migration from the Kuiper Belt (where blackbody temperatures are ∼40 K) to Jupiter’s orbit (∼125 K). Here, we examine the optical color distribution of the Neptunian Trojans using a combination of new optical photometry and published data. We find a color distribution that is statistically indistinguishable from that of the Jovian Trojans but unlike any sub-population in the Kuiper Belt. This result is puzzling, because the Neptunian Trojans are very cold (blackbody temperature ∼50 K) and a thermal process acting to modify the surface colors at Neptune’s distance would also affect the Kuiper Belt objects beyond, where the temperatures are nearly identical. The distinctive color distributions of the Jovian and Neptunian Trojans thus present us with a conundrum: they are very similar to each other, suggesting either capture from a common source or surface modification by a common process. However, the color distributions differ from any plausible common source population, and there is no known modifying process that could operate equally at both Jupiter and Neptune.

  16. Ultracold fermion race is on

    International Nuclear Information System (INIS)

    Hulet, R.

    1999-01-01

    At the quantum level, particles behave very differently depending on whether their spin angular momentum is an integer or a half-integer. Half-integer spin particles are known as fermions, and include all the constituents of atoms: electrons, protons and neutrons. Bosons, on the other hand, are particles with integer spin, such as photons. Atoms are fermions if they are composed of an odd number of particles, like helium-3 or lithium-6. If they have an even number of constituents, like hydrogen, helium-4 or lithium-7, they are known as bosons. Fermions and bosons behave in profoundly different ways under certain conditions, especially at low temperatures. Four years ago, physicists created a Bose condensate, a quantum degenerate gas of bosons. Now the race is on to do the same with fermions. Deborah Jin's group at the US National Institute of Standards and Technology (NIST) and the University of Colorado has cooled a fermion gas to the lowest temperature yet (B DeMarco 1999 Phys. Rev. Lett. 82 4208). And John Thomas and co-workers at Duke University have set a new record for the length of time that fermions can be trapped using lasers (K O'Hara 1999 Phys. Rev. Lett. 82 4204). In this article the author describes the latest advances in the race to create a quantum degenerate gas of fermions. (UK)

  17. Hypertension Risk Subsequent to Gestational Dysglycemia Is Modified by Race/Ethnicity.

    Bentley-Lewis, Rhonda; Huynh, Jennifer; Li, Sylvia; Wenger, Julia; Thadhani, Ravi

    2016-01-01

    Gestational diabetes mellitus is associated with an increased risk of type 2 diabetes mellitus and hypertension. Additionally, gestational dysglycemia has been associated with an increased risk of type 2 diabetes mellitus but not yet associated with hypertension subsequent to pregnancy in long-term follow-up. Therefore, we set out to examine this relationship as well as the role of race/ethnicity in modifying this relationship. We analyzed a prospective observational cohort followed between 1998 and 2007. There were 17 655 women with self-reported race/ethnicity and full-term, live births. A 1-hour 50 g oral glucose-load test and a 3-hour 100 g oral glucose-tolerance test enabled third trimester stratification of women into 1 of 4 glucose-tolerance groups: (1) normal (n=15 056); (2) abnormal glucose-load test (n=1558); (3) abnormal glucose-load and -tolerance tests (n=520); and (4) gestational diabetes mellitus (n=521). Women were then followed for a mean±standard deviation of 4.1±2.9 years after delivery for the development of hypertension. Although gestational diabetes mellitus was associated with an increased risk of hypertension after pregnancy (odds ratio [95% confidence interval]: 1.58 [1.02, 2.45]; P=0.04), dysglycemia defined by an abnormal glucose-load test predicted hypertension only among black women (4.52 [1.24, 16.52]; P=0.02). The risk of hypertension after pregnancy among dysglycemia groups not meeting criteria for gestational diabetes mellitus varied based on the race/ethnicity of the population. Further research on the implications of the intersection of race/ethnicity and gestational dysglycemia on subsequent hypertension is warranted. © 2015 American Heart Association, Inc.

    2018-05-17

    During pregnancy thyroid hormones have profound effects on embryonal/fetal development and maternal health. Therefore, thyroid gland disorders should be immediately diagnosed and adequately treated. Pregnancy-specific physiological alterations during pregnancy cause changes in the reference interval for thyroid-stimulating hormone levels and trimester-specific thresholds must be taken into account. This article summarizes the most important diagnostic and therapeutic aspects before, during and after pregnancy. With reference to the period prior to pregnancy, the article discusses iodide supplementation, preconceptional examination of thyroid gland metabolism and the importance of thyroid gland functional disorders for fertility and fulfilling the desire to have children. With a view to the period during pregnancy, the effect of hypothyroxinemia, hypothyroidism, and hyperthyroidism as well as the effects of their treatment on the development of the child are explained. Finally, a description is given of what must be paid attention to in the breast-feeding period and in postpartum thyroiditis.

Pregnancy loss is often divided in two categories: early pregnancy loss (EPL or embryonic death (ED (first 42 days and fetal losses (after 42 days. Diagnosis of the causes of pregnancy loss is often very challenging. Many of the causes of EPL remain poorly documented but studies on embryo development and embryo-uterine interaction have been able to shed some light on predisposing factors. Fetal losses or abortions are dominated by infectious causes and particularly bacterial placentitis. Detailed reviews of pregnancy loss were recently published by the authors (Tibary et al., 2012; Tibary and Pearson, 2012; Tibary et al., 2014. The objective of this paper is to provide an overview of the epidemiology, etiology, diagnosis and prevention of pregnancy loss in the mare.

    Full Text Available Visual obscurations are common during pregnancy. The ocular effects of pregnancy may be physiological,pathological or may be modifications of pre-existing conditions. While most of the described changes are transient in nature, others extend beyond delivery and may lead to permanent visual impairment. Also, pregnancy can affect vision through systemic disease that are either specific to the pregnancy itself or systemic diseases that occur more frequently in relation to pregnancy. Neuro-ophthalmological disorders should be kept in mind in pregnant women presenting with visual acuity or field loss. Therefore, it is important to be aware of the ocular changes in pregnancy in order to counsel and advice women who currently are, or are planning to become pregnant.

    We intend to describe the sexual behaviour of pregnancies women. Family Planning Center Nóvoa Santos, of Galician Health Service (SERGAS), of Ourense (SPAIN). 206 pregnancies women that are attended in a obstetric psychoprophylaxis's programme, during two years (January/93-January/95). We analysed the social economic, of reproduction, of medical attention and psycho-sexual variables. We use the PRESTA and SPSS statistics programmes. The average age is 28 years old, is married, has elementary studies and this is the first pregnancy. Her pregnancy is desire and normally developed. Her sexual desire and intercourse frequency is the same (1-2 per week); the intercourse is pleasant and the more habitual position is she over. Some times, the couple has relations without coitus and she practises the masturbation, and she enjoy of this practice. The pregnancies women have different sexual behaviours. They are satisfied with all them. The health' professional should favour the complete enjoy of the sexuality during the pregnancy.

    Abdominal pregnancy, a rare diagnosis, belongs to the ectopic pregnancy group, the leading cause of pregnancy related exitus. The positive diagnosis is very difficult to establish most often in an acute setting, leading to a staggering percent of feto-maternal morbidity and mortality. We present the case of 26-weeks-old abdominal pregnancy with partial feto-placental detachment in a patient, after hysteroscopy and in vitro fertilization, which until the acute symptoms that led to emergency laparotomy went unrecognized. The patient recovered completely and satisfactorily after surgery and, due to the high risk of uterine rupture with regard to a second pregnancy, opted for a surrogate mother. Abdominal pregnancy can be regarded as a difficult to establish diagnosis, with a greater chance in case of increased awareness. It is compulsory to be well informed in order not to be surprised by the diagnosis and to apply the correct treatment immediately as the morbidity and mortality rate is elevated.

    Full Text Available In this article, we present a case of subacute thyroiditis occurring in the first trimester of pregnancy in a 33-years-old pregnant patient. Thyrotoxicosis during pregnancy is a rare condition and occurs in 0.1 to 0.4% of all pregnancies. Graves' Disease and transient gestational thyrotoxicosis constitute the majority of emerging thyrotoxicosis during pregnancy. Subacute thyroiditis may also cause temporary thyrotoxicosis. Although the majority of the patients recover without treatment, complications in the pregnancy should be considered and each patient must be evaluated individually. As a result, differential diagnosis of thyrotoxicosis in pregnancy and treatment plan should be done well and subacute thyroiditis should be considered in differential diagnosis.

    Full Text Available A total of 47 racing greyhounds were enrolled in this study on two race days (in July and September, resp. at a racetrack. Twelve of the dogs participated in the study on both days. Thermographic images were taken before and after each race. From the images, superficial temperature points of selected sites (tendo calcaneus, musculus gastrocnemius, musculus gracilis, and musculus biceps femoris portio caudalis were taken and used to investigate the differences in superficial temperatures before and after the race. The thermographic images were compared between the right and left legs of a dog, between the raced distances, and between the two race days. The theoretical heat capacity of a racing greyhound was calculated. With regard to all distances raced, the superficial temperatures measured from the musculus gastrocnemius were significantly higher after the race than at baseline. No significant differences were found between the left and right legs of a dog after completing any of the distances. Significant difference was found between the two race days. The heat loss mechanisms of racing greyhounds during the race through forced conduction, radiation, evaporation, and panting can be considered adequate when observing the calculated heat capacity of the dogs.

    Heterotopic pregnancy occurs when intrauterine and ectopic pregnancy are concomitant; overall rate rises from 1/30.000 to 1.5/1000 in assisted reproductive technology pregnancies. HIV (human immunodeficiency virus) patients are at increased risk of heterotopic pregnancies due to the greater frequency of assisted reproductive technology and pelvic inflammatory disease. We report the first case of heterotopic pregnancy in HIV woman.

    The purpose of this research project was to investigate the relationship between skin color and level of perceived physical attractiveness. Previous research suggested that skin color plays an important role in how we perceive an individual's physical attractiveness. The current study was conducted to determine how influential the role of race is on perceptions of physical attractiveness. In this study, 79 subjects were asked to evaluate images of potential endorsers to be used in an upcoming advertising campaign. The images were those of females of varying skin tones. Data were then collected and analyzed to determine whether skin tone and level of skin color can in fact influence the physical attractiveness stereotype.

    Pregnancy is a predisposing factor for urinary tract infection and pregnant women suffering from this pathology are exposed to dangerous risks which may condition maternal wellbeing and fetal prognosis. Asymptomatic bacteriuria is the common bacterial infection requiring medical treatment in pregnancy. Diagnosis and treatment of asymptomatic bacteriuria is important as approximately 20-40% of these women, if untreated during pregnancy, will develop a symptomatic urinary tract infection.

    I derive fully covariant equations of motion for a classical colored spinning particle in an external SU(3) color field. Although the total color charge and total spin of the particle are found to be separately constants of motion (here I disagree with a recent paper by Arodz), the dynamics of the orientation of the color and spin vectors are coupled to each other through interaction with the color field, even if the latter is homogeneous.

    The authors sought to determine whether pregnancies in adolescents following an abortion of pregnancy is associated with an elevated risk for adverse perinatal outcomes. In a cohort study of all adolescent (younger than 18 years) deliveries over a 4-year period at 1 institution, we compared nulliparous women with a history of a prior abortion (cases) to those without a spontaneous loss or abortion of pregnancy (referent) for adverse perinatal outcomes, including preterm birth and fetal growth restriction. Of the 654 included nulliparous adolescent deliveries, 102 (16%) had an abortion before the index pregnancy. Compared with the referent group, adolescents with a history of a abortion were older (17.8 ± 0.8 vs 16.7 ± 1.2 years, P = .0001), enrolled earlier for prenatal care (14.4 ± 5.6 vs 17.2 ± 7.6 weeks, P = .0004), along with a higher incidence of African American race (95% vs 88%, P = .05). The groups did not differ with respect to other maternal demographics. Perinatal outcomes, including spontaneous preterm birth, abnormal placentation, birth weight, and gestational age at delivery, did not differ between the 2 groups. Compared with adolescent women who had just delivered and did not have a prior abortion, women who had just delivered and had a previous abortion were more likely to be older at the age of their first pregnancy and more likely to initiate early prenatal care. Thus, having a prior abortion may improve the health of a pregnancy though adverse outcomes do not differ between the 2 groups.

    Full Text Available This paper is guided by the theoretical notion that social divisions generate effects derived from its structural interaction. Having in mind this theoretical motivation, it estimates the gender earnings gap among white e non white (black and mixed color groups in Brazil. All the eight Generalized Linear Models estimated, whose variables are successively included, show that the gender gap is big across both racial groups but it is bigger among whites. The investigation explores the role of the underlying context of class inequality, as well as others factors, on understanding the racial variation of the gender inequality. The study considers that the characteristics of the racial inequality in Brazil, as well as the intersection between class and race, explain the bigger gender advantage for the white man. The racial hierarchy establishes limits of variation on the gender hierarchy for the non white.

    This study uses epidemiological data to investigate socioeconomic proportions of distinctions raised by "racism" in Brazilian society. A population-based cross-sectional study was conducted with a sample of 2,779 women ages 14 through 49, living in a southern Brazilian city. Black and mixed-race women had less schooling, lower family income, and worse housing conditions than white women. They also used contraceptive methods less frequently, had more children, and had higher spontaneous abortion and stillbirth rates than white women. Virtually all of the results show a linear relationship between such categories, i.e., the "darker" the woman's skin color, the worse her socioeconomic and reproductive conditions. We also observed that black women were either separated, divorced, or widowed, another apparent factor for black women's impoverishment, related mainly to their limited employment opportunities. The results of the current study indicate that racial relations among women are an issue that should foster a discussion concerning citizenship in Brazil.
