Payne, K

1995-02-01

In this interview, Alzira Rufino describes her involvement in the feminist movement and what caused her to found the Black Women's House of Culture in Brazil in 1990. Rufino located the center in Santos because it is a port city which sees a great deal of violence and is very sexist and racist. The center, which exists to assist all women, grew out of a Rufino's realization that Black women needed a group to support their rights. The name for the center came from the fact that women have been the keepers of African culture in Brazil. In Brazil, White men dominate the culture, even the cultural expressions produced by Black people such as the Carnival. The center has had to overcome the criticism directed at it because it was created for women and for Black women in particular, and Black feminists are beginning to understand that Black women make up 25% of the population of Brazil and must celebrate their heritage. Increasing the self-esteem of Black women can be instrumental in helping women undergo training for better jobs and to take the initiative to become entrepreneurs. Black women in Brazil are beginning to occupy positions formerly denied them and to denounce the racism and sexism directed toward them.

Pierre, Martin R; Mahalik, James R

2005-02-01

This study investigated African self-consciousness and Black racial identity as predictors of psychological distress and self-esteem for Black men. One hundred thirty Black men from a college and community sample completed the African Self-Consciousness Scale, the Racial Identity Attitude Scale-B, the Symptom Checklist 90-Revised, and the Coopersmith Self-Esteem Inventory. Canonical correlation analysis found 2 significant roots with the 1st root indicating that Black men whose attitudes reflected Preencounter and Immersion racial identity attitudes and who do not resist against anti-African/Black forces reported greater psychological distress and less esteem. Results from the 2nd root suggested that Black men whose attitudes reflect greater Internalization racial identity attitudes, greater resistance to anti-African/Black forces, and less identification with Blacks reported greater self-esteem.

Quantum tunneling radiation from self-dual black holes

International Nuclear Information System (INIS)

Silva, C.A.S.; Brito, F.A.

2013-01-01

Black holes are considered as objects that can reveal quantum aspects of spacetime. Loop Quantum Gravity (LQG) is a theory that propose a way to model the quantum spacetime behavior revealed by a black hole. One recent prediction of this theory is the existence of sub-Planckian black holes, which have the interesting property of self-duality. This property removes the black hole singularity and replaces it with another asymptotically flat region. In this work, we obtain the thermodynamical properties of this kind of black holes, called self-dual black holes, using the Hamilton–Jacobi version of the tunneling formalism. Moreover, using the tools of the tunneling approach, we investigate the emission spectrum of self-dual black holes, and investigate if some information about the black hole initial state can be recovered during the evaporation process. Back-reaction effects are included

The relationships among Black consciousness, self-esteem, and academic self-efficacy in African American men.

Okech, Allan Prince; Harrington, Rick

2002-03-01

The purpose of this study was to investigate the relationships among Black consciousness, self-esteem, and academic self-efficacy in African American men. The participants were 120 African American male college students at a predominantly African American university. The authors administered 3 instruments--the Developmental Inventory of Black Consciousness (DIB-C; J. Milliones, 1980), the M. Rosenberg (1965) Self-Esteem Scale, and R. E. Wood and E. A. Locke's (1987) Academic Self-Efficacy Scale--to test the hypotheses. They used an independent-measures t test and a Pearson r correlation to analyze the data. The results of the study supported the hypotheses under investigation. Significant positive relationships were found between Black consciousness and self-esteem and Black consciousness and academic self-efficacy. The results of the study showed that Black consciousness appears to be an important construct to use in understanding self-esteem and academic self-efficacy in African American men.

BLACK HOLE-GALAXY CORRELATIONS WITHOUT SELF-REGULATION

International Nuclear Information System (INIS)

Anglés-Alcázar, Daniel; Özel, Feryal; Davé, Romeel

2013-01-01

Recent models of black hole growth in a cosmological context have forwarded a paradigm in which the growth is self-regulated by feedback from the black hole itself. Here we use cosmological zoom simulations of galaxy formation down to z = 2 to show that such strong self-regulation is required in the popular spherical Bondi accretion model, but that a plausible alternative model in which black hole growth is limited by galaxy-scale torques does not require self-regulation. Instead, this torque-limited accretion model yields black holes and galaxies evolving on average along the observed scaling relations by relying only on a fixed, 5% mass retention rate onto the black hole from the radius at which the accretion flow is fed. Feedback from the black hole may (and likely does) occur, but does not need to couple to galaxy-scale gas in order to regulate black hole growth. We show that this result is insensitive to variations in the initial black hole mass, stellar feedback, or other implementation details. The torque-limited model allows for high accretion rates at very early epochs (unlike the Bondi case), which if viable can help explain the rapid early growth of black holes, while by z ∼ 2 it yields Eddington factors of ∼1%-10%. This model also yields a less direct correspondence between major merger events and rapid phases of black hole growth. Instead, growth is more closely tied to cosmological disk feeding, which may help explain observational studies showing that, at least at z ∼> 1, active galaxies do not preferentially show merger signatures.

Association Between Self-Esteem and Depressive Symptoms Is Stronger Among Black than White Older Adults.

Science.gov (United States)

Assari, Shervin

2017-08-01

Although poor self-esteem is a core component of depression, we still do not know if racial and ethnic groups differ in the magnitude of this link. This study compared Black and White older adults on the association between self-esteem and depressive symptoms. With a cross-sectional design, this study enrolled 1493 older individuals (age 66 or more) from the 2001 Religion, Aging, and Health Survey, a nationally representative study in the United States. Participants were either Blacks (n = 734) or Whites (n = 759). Depressive symptoms and self-esteem were measured using brief measures of the Center for Epidemiological Studies-Depression scale (CES-D) and the Rosenberg Self-Esteem Scale, respectively. Demographics, socioeconomics, and self-rated health (SRH) were covariates and self-identified race was the moderator. Linear regression models were used for data analysis. Low self-esteem was associated with more depressive symptoms (B = 0.17, 95 % CI 0.15-0.28), above and beyond all covariates. We found a significant and positive interaction between race (Black) and poor self-esteem on depressive symptoms (B = 0.34, 95 % CI 0.17-0.36), suggesting a stronger association between self-esteem and depressive symptoms among Blacks compared to Whites. Although low self-esteem is associated with higher depressive symptoms in both Whites and Blacks (p self-esteem and high depressive symptoms are more closely associated among Blacks than Whites. It is not clear whether depression leaves a larger scar on self-esteem for Blacks, or Blacks are more vulnerable to the effect of low self-esteem on depression.

Bancroft, John; Long, J Scott; McCabe, Janice

2011-08-01

In the United States, considerable attention has been directed to sexual behaviors of black and white adolescents, particularly age at first sexual experience and the prevalence of teenage pregnancies. More limited attention has been paid to comparing established sexual relationships in these two racial groups. In this study, we used a national probability sample to compare black (n = 251) and white (n = 544) American women, aged 20-65 years, who were in an established heterosexual relationship of at least 6 months duration. We focused on two aspects of their sexual well-being; how a woman evaluated (1) her sexual relationship and (2) her own sexuality. A range of possible determinants of sexual well-being, including demographic factors, physical and mental health, and aspects of the women's recent sexual experiences, were also assessed using Telephone-Audio-Computer-Assisted Self-Interviewing (T-ACASI). We found no significant difference between black and white women in their evaluation of their sexual relationships nor in the independent variables that were correlated with this evaluation. Black women, however, evaluated their own sexuality more positively than white women. In examining the correlates of this evaluation, a woman's rating of her own sexual attractiveness proved to be the strongest predictor, with black women rating themselves significantly more sexually attractive than did the white women. Overall, these findings were consistent with previous findings that, compared to white women, black women in the United States have higher self-esteem and tend towards more independence and individualism.

VIOLENT BLACK MAN AND THE MYTH OF BLACK MACHO IN EUGENE O’NEILL’S "THE DREAMY KID"

Directory of Open Access Journals (Sweden)

Agnieszka Łobodziec

2014-10-01

Full Text Available The aim of this article is the investigation of the extent to which Eugene O’Neill, in his drama "The Dreamy Kid", (reconstructs, or employs, the black macho myth, which negatively images black men as marginalized and violent. This undertaking questions O’Neill’s self-proclaimed progressive racial attitudes and stated focus on the universal nature of human existence, which he professed to express through drama. Moreover, the article challenges the mainstream view of "The Dreamy Kid" as progressive. Although the play focalizes the experience of a marginalized black man, which could be interpreted as the playwright’s concern with the unjust racial and class stratification of American society, O’Neill’s production, unfortunately, contains a number of pervasive stereotypes relative to black people’s alleged moral degeneracy, primitiveness, and violent behavior, which threatens the white dominated constructed order. In terms of gendered racial politics, in the article attention is given to O’Neill’s presentation of black male negotiations with the white patriarchal power structure, embodied by the police forces, and with black matriarchy, represented by O’Neill’s stereotypical character portrayal of a dominant elderly black woman. Lastly, an overall analysis is performed in light of the call for an autonomous black art, which emerged among black artists in opposition to the demeaning, unrealistic, stereotypical portrayals of black victims of oppression by white American writers.

Planckian charged black holes in ultraviolet self-complete quantum gravity

Science.gov (United States)

Nicolini, Piero

2018-03-01

We present an analysis of the role of the charge within the self-complete quantum gravity paradigm. By studying the classicalization of generic ultraviolet improved charged black hole solutions around the Planck scale, we showed that the charge introduces important differences with respect to the neutral case. First, there exists a family of black hole parameters fulfilling the particle-black hole condition. Second, there is no extremal particle-black hole solution but quasi extremal charged particle-black holes at the best. We showed that the Hawking emission disrupts the condition of particle-black hole. By analyzing the Schwinger pair production mechanism, the charge is quickly shed and the particle-black hole condition can ultimately be restored in a cooling down phase towards a zero temperature configuration, provided non-classical effects are taken into account.

Wonder Woman for a day: Affect, agency, and Amazons

2012-06-01

Full Text Available In this paper, I consider the ways in which the feminist utopian ethos of Wonder Woman, as defined by her creator, William Marston, has been used to actualize real-life social change. Specifically, I examine fan Andy Mangels's creation of Wonder Woman Day, a charity event held annually at a Portland, Oregon, comic book store to raise funds for local domestic violence programs. I look at how an affective bond with Wonder Woman informs and guides an affective attachment to one's local and national communities, actualizing the utopian promise of self, commodity icon, and America. These utopian iterations are primarily defined by a celebration of pluralism, and thus Wonder Woman is used to validate the inherent pluralism of the self in relation to society, an empowering strategy for all consumer-citizens.

Assari, Shervin; Moghani Lankarani, Maryam

2018-06-11

Background. Poor self-esteem is a core element of depression. According to recent research, some racial groups may vary in the magnitude of the link between depression and poor self-esteem. Using a national sample, we compared Black and White older Americans for the effect of baseline depressive symptoms on decline in self-esteem over time. Methods. This longitudinal study used data from the Religion, Aging, and Health Survey, 2001⁻2004. The study followed 1493 older adults (734 Black and 759 White) 65 years or older for three years. Baseline depressive symptoms (CES-D), measured in 2001, was the independent variable. Self-esteem, measured at the end of the follow up, was the dependent variable. Covariates included baseline demographic characteristics (age and gender), socioeconomic factors (education, income, and marital status), health (self-rated health), and baseline self-esteem. Race/ethnicity was the moderator. Linear multi-variable regression models were used for data analyses. Results. In the pooled sample, higher depressive symptoms at baseline were predictive of a larger decline in self-esteem over time, net of covariates. We found a significant interaction between race/ethnicity and baseline depressive symptoms on self-esteem decline, suggesting a weaker effect for Blacks compared to Whites. In race/ethnicity-specific models, high depressive symptoms at baseline was predictive of a decline in self-esteem for Whites but not Blacks. Conclusion. Depressive symptoms may be a more salient contributor to self-esteem decline for White than Black older adults. This finding has implications for psychotherapy and cognitive behavioral therapy of depression of racially diverse populations.

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

The effect of survivalism--self-expressionism culture on black male suicide acceptability: a cross-national analysis.

Science.gov (United States)

Stack, Steven; Kposowa, Augustine J

2011-04-01

Cultural explanations of black suicide have focused on the US and stressed religiosity as a protective factor. This paper adds to this literature by (1) expanding the analysis of the impact of religiosity on black suicide to 10 nations, and (2) assessing the extent to which a broader cultural construct (self expressionism) affects black suicide acceptability. Data are from Wave 4 of the World Values Surveys 1991-2001 and refer to 3580 black males nested in ten countries. A hierarchical linear regression model determined that religiosity predicted black suicide acceptability across ten nations. Self expressionism was positively associated with individual level suicide acceptability. Further, a cross-level interaction was found wherein individual level and societal level self expressionism combined to affect suicide acceptability. The variability in suicide acceptability among black males is predicted, in part, by both individual and group levels of adherence to values contained in a major cultural axis of nations: self expressionism. These new found associations compliment the impact of a standard predictor, religiosity, on suicide acceptability. Copyright © 2011 Elsevier Ltd. All rights reserved.

Self-gravitating black hole scalar wigs

Barranco, Juan; Bernal, Argelia; Degollado, Juan Carlos; Diez-Tejedor, Alberto; Megevand, Miguel; Núñez, Darío; Sarbach, Olivier

2017-07-01

It has long been known that no static, spherically symmetric, asymptotically flat Klein-Gordon scalar field configuration surrounding a nonrotating black hole can exist in general relativity. In a series of previous papers, we proved that, at the effective level, this no-hair theorem can be circumvented by relaxing the staticity assumption: for appropriate model parameters, there are quasibound scalar field configurations living on a fixed Schwarzschild background which, although not being strictly static, have a larger lifetime than the age of the universe. This situation arises when the mass of the scalar field distribution is much smaller than the black hole mass, and following the analogies with the hair in the literature we dubbed these long-lived field configurations wigs. Here we extend our previous work to include the gravitational backreaction produced by the scalar wigs. We derive new approximate solutions of the spherically symmetric Einstein-Klein-Gordon system which represent self-gravitating scalar wigs surrounding black holes. These configurations interpolate between boson star configurations and Schwarzschild black holes dressed with the long-lived scalar test field distributions discussed in previous papers. Nonlinear numerical evolutions of initial data sets extracted from our approximate solutions support the validity of our approach. Arbitrarily large lifetimes are still possible, although for the parameter space that we analyze in this paper they seem to decay faster than the quasibound states. Finally, we speculate about the possibility that these configurations could describe the innermost regions of dark matter halos.

I'm a Jesus girl: coping stories of Black American women diagnosed with breast cancer.

Science.gov (United States)

Gregg, Godfrey

2011-12-01

Breast cancer continues to be the most diagnosed cancer for all women, excluding non-melanoma skin cancer, in the United States. Incidence rates are 1 in 8 for an American woman being diagnosed. Moreover, statistics indicate that every 13 min an American woman dies from complications related to breast cancer. Despite all the gains made in the area of cancer research, Black American women continue to have a 67% higher mortality rate than their White counterparts. There is no preparation for a diagnosis of breast cancer. Upon hearing the words: you have breast cancer, a woman's life is forever altered. The woman's initial reactions of denial and/or anger yield to strategic responses. These responses may strengthen the woman's resiliency both during and following treatments. Research indicates that Black Americans, specifically Black American women, exhibit greater religiosity/spirituality than do other racial/ethnic groups. In addition, the use of religiosity/spirituality by Black Americans increases during a crisis. This qualitative study examines how religiosity/spirituality was utilized as a coping mechanism by a group of Black American women following their diagnoses of breast cancer.

Landau-Ginzburg Limit of Black Hole's Quantum Portrait: Self Similarity and Critical Exponent

CERN Document Server

Dvali, Gia

2012-01-01

Recently we have suggested that the microscopic quantum description of a black hole is an overpacked self-sustained Bose-condensate of N weakly-interacting soft gravitons, which obeys the rules of 't Hooft's large-N physics. In this note we derive an effective Landau-Ginzburg Lagrangian for the condensate and show that it becomes an exact description in a semi-classical limit that serves as the black hole analog of 't Hooft's planar limit. The role of a weakly-coupled Landau-Ginzburg order parameter is played by N. This description consistently reproduces the known properties of black holes in semi-classical limit. Hawking radiation, as the quantum depletion of the condensate, is described by the slow-roll of the field N. In the semiclassical limit, where black holes of arbitrarily small size are allowed, the equation of depletion is self similar leading to a scaling law for the black hole size with critical exponent 1/3.

Measurement Noninvariance of Safer Sex Self-Efficacy Between Heterosexual and Sexual Minority Black Youth.

Science.gov (United States)

Gerke, Donald; Budd, Elizabeth L; Plax, Kathryn

2016-01-01

Black and lesbian, gay, bisexual, or questioning (LGBQ) youth in the United States are disproportionately affected by HIV and other sexually transmitted diseases (STDs). Although self-efficacy is strongly, positively associated with safer sex behaviors, no studies have examined the validity of a safer sex self-efficacy scale used by many federally funded HIV/STD prevention programs. This study aims to test factor validity of the Sexual Self-Efficacy Scale by using confirmatory factor analysis (CFA) to determine if scale validity varies between heterosexual and LGBQ Black youth. The study uses cross-sectional data collected through baseline surveys with 226 Black youth (15 to 24 years) enrolled in community-based HIV-prevention programs. Participants use a 4-point Likert-type scale to report their confidence in performing 6 healthy sexual behaviors. CFAs are conducted on 2 factor structures of the scale. Using the best-fitting model, the scale is tested for measurement invariance between the 2 groups. A single-factor model with correlated errors of condom-specific items fits the sample well and, when tested with the heterosexual group, the model demonstrates good fit. However, when tested with the LGBQ group, the same model yields poor fit, indicating factorial noninvariance between the groups. The Sexual Self-Efficacy Scale does not perform equally well among Black heterosexual and LGBQ youth. Study findings suggest additional research is needed to inform development of measures for safer sex self-efficacy among Black LGBQ youth to ensure validity of conceptual understanding and to accurately assess effectiveness of HIV/STD prevention interventions among this population.

Self-Regular Black Holes Quantized by means of an Analogue to Hydrogen Atoms

We suggest a proposal of quantization for black holes that is based on an analogy between a black hole and a hydrogen atom. A self-regular Schwarzschild-AdS black hole is investigated, where the mass density of the extreme black hole is given by the probability density of the ground state of hydrogen atoms and the mass densities of non-extreme black holes are chosen to be the probability densities of excited states with no angular momenta. Consequently, it is logical to accept quantization of mean radii of hydrogen atoms as that of black hole horizons. In this way, quantization of total black hole masses is deduced. Furthermore, the quantum hoop conjecture and the Correspondence Principle are discussed.

The purpose of this research effort was to examine Black male students' self-perceptions of academic ability and gifted potential in science. The purposeful sample consisted of nine Black males between the ages of 14 and 18 years. Four categories of self-perceptions of academic ability and gifted potential emerged from the data. These included: (a) gifted high achievers; (b) gifted could do better high achievers; (c) gifted could do better situational nonachievers; and (d) gifted could do better underachievers. Science teachers' influences that referenced participants' academic achievement pointed to validation. Participants' perceptions regarding how science teachers' influenced their academic performance focused on science teachers' content knowledge. Power dynamics germane to Black male participants' value or worth that directed their efforts in science learning environments are discussed. Implications are posited for science teaching, science education programs, and future research. This research endeavor was based on two premises. The first premise is that Black males' self-perceptions of academic ability affect their science academic achievement. The second premise is that, given parental, peer, and community influences, science teachers have considerable influence on students' self-perceptions of academic ability. However, the focus of this research was not on parental influences, peer influences, or any potential influences that participants' communities may have on their academic achievement.

Discrimination is related to depression and poor self-esteem among Black men. Poorer self-esteem is also associated with depression. However, there is limited research identifying how self-esteem may mediate the associations between discrimination and depressive symptoms for disparate ethnic groups of Black men. The purpose of this study was to examine ethnic groups as a moderator of the mediating effects of self-esteem on the relationship between discrimination and depressive symptoms among a nationally representative sample of African American (n = 1201) and Afro-Caribbean American men (n = 545) in the National Survey of American Life. Due to cultural socialization differences, we hypothesized that self-esteem would mediate the associations between discrimination and depressive symptoms only for African American men, but not Afro-Caribbean American men. Moderated-mediation regression analyses indicated that the conditional indirect effects of discrimination on depressive symptoms through self-esteem were significant for African American men, but not for Afro-Caribbean men. Our results highlight important ethnic differences among Black men.

We examine trends in self-employment among white and black men from 1910 to 1990 using Census and CPS microdata. Self-employment rates fell over most of the century and then started to rise after 1970. For white men, we find that the decline was due to declining rates within industries, but was counterbalanced somewhat by a shift in employment towards high self-employment industries. Recently, the increase in self-employment was caused by an end to the within industry decline and the continui...

A regular black hole model, which has been proposed by Hayward (2006) in , is reconsidered in the framework of higher dimensional TeV unification and self-complete quantum gravity scenario (Dvali and Gomez (2010) , Dvali, Folkerts and Germani (2010) , Spallucci and Ansoldi (2011) ). We point out the 'quantum' nature of these objects and compute their cross section production by taking into account the key role played by the existence of a minimal lengthl{sub 0}. We show that the threshold energy is related to l{sub 0}. We recover, in the high energy limit, the standard 'black-disk' form of the cross section, while it vanishes, below threshold, faster than any power of the invariant mass energy {radical}(-s).

Perfectionistic Self-Presentation and Suicide in a Young Woman with Major Depression and Psychotic Features

2014-01-01

A woman in her midtwenties with a history of major depressive disorder and a recent major depressive episode with mood-congruent psychotic features died by suicide. Two weeks before her death, she demonstrated exceptional elevations on the nondisplay of imperfection factor of Hewitt and Flett's Perfectionistic Self-Presentation Scale. Perfectionism and especially perfectionistic self-presentation have been strongly associated with suicide across several populations, accounting for unique variance in suicidality beyond depression and hopelessness. Yet interpersonal facets of perfectionism are not recognized as clinical risk factors for suicide. There is also a paucity of research on perfectionism in relation to psychotic symptoms. This case account illustrates the role of perfectionistic self-presentation in suicides that occur seemingly without warning and, to our knowledge, this is the first examination of perfectionistic self-presentation and suicide in a case where psychotic features occurred. This study, though single case-based, draws attention to perfectionism and perfectionistic self-presentation and their potential roles in suicide, especially when accompanied by other risk factors. Future research in this area may elucidate the role of perfectionism in suicide, singularly and in the context of a comprehensive clinical risk assessment, demonstrating whether perfectionism confers information about suicide risk beyond known clinical risk factors.

Full Text Available This study examines the career women who use the habit of treating the body through the routine of coming to spas, which aims to overcome the dominance of patriarchy. This study uses several concepts. First, muted group theory, which states that woman, is the one that silenced; so to overcome this condition, women should perform self-transformation. The transformation is aligned with the second concept, feminist existentialist, which defines the transformation as the change of a woman concept from Other to Self. The transformation can be achieved not only by working outside the domestic sphere, but also supported by a good appearance through a complete body treatment. Grooming habits acquired through socialization that derived in woman since their childhood. The socialization is about how women as a person who is considered weak by the world of patriarchal domination using the power of their beauty to master, subdue, and break the domination in her life. Then, with their good appearance, woman can express their existence in everything that they do from object become subject. Spa and the whole result of the activities contained in it then consciously become a way of resistance that being used by the career woman against the domination of patriarchy which overshadowing their lives. 

Black hole algorithm for determining model parameter in self-potential data

Sungkono; Warnana, Dwa Desa

2018-01-01

Analysis of self-potential (SP) data is increasingly popular in geophysical method due to its relevance in many cases. However, the inversion of SP data is often highly nonlinear. Consequently, local search algorithms commonly based on gradient approaches have often failed to find the global optimum solution in nonlinear problems. Black hole algorithm (BHA) was proposed as a solution to such problems. As the name suggests, the algorithm was constructed based on the black hole phenomena. This paper investigates the application of BHA to solve inversions of field and synthetic self-potential (SP) data. The inversion results show that BHA accurately determines model parameters and model uncertainty. This indicates that BHA is highly potential as an innovative approach for SP data inversion.

Woman to Woman (W2W) is a novel adaptation of the Sisters Informing Sisters about Topics on AIDS (SISTA) HIV prevention program. This article describes the process of adapting and piloting W2W based on recommendations from existing HIV prevention research. Six older women, all of whom had histories of homelessness and the majority of whom identified as African American, enrolled in the study, which piloted the adapted intervention and materials, evaluated the acceptability of the program, and assessed the measures related to the intervention. Participants described satisfaction with the program and had high rates of attendance; observations regarding the measures suggest the need to further develop assessments of HIV knowledge, condom use self-efficacy, and risk behaviors in this context.

Self-castration by a transsexual woman: financial and psychological costs: a case report.

Science.gov (United States)

St Peter, Matthew; Trinidad, Anton; Irwig, Michael S

2012-04-01

The out-of-pocket cost for an elective orchiectomy, which is often not covered by health insurance, is a significant barrier to male-to-female transsexuals ready to proceed with their physical transition. This and other barriers (lack of access to a surgeon willing to perform the operation, waiting times, and underlying psychological and psychiatric conditions) lead a subset of transsexual women to attempt self-castration. Little information has been published on the financial costs and implications of self-castration to both patients and health care systems. We compare the financial and psychological costs of elective surgical orchiectomy vs. self-castration in the case of a transsexual woman in her 40s. We interviewed the patient and her providers and obtained financial information from local reimbursement and billing specialists. After experiencing minor hemorrhage following the self-castration, our patient presented to the emergency department and underwent a bilateral inguinal exploration, ligation and removal of bilateral spermatic cords, and complicated scrotal exploration, debridement, and closure. She was admitted to the psychiatric service for a hospital stay of three days. The total bill was U.S. $14,923, which would compare with U.S. $4,000 for an elective outpatient orchiectomy in the patient's geographical area. From a financial standpoint, an elective orchiectomy could have cost the health care system significantly less than a hospital admission with its associated additional costs. From a patient safety standpoint, elective orchiectomy is preferable to self-castration which carries significant risks such as hemorrhage, disfigurement, infection, urinary fistulae, and nerve damage. Healthcare providers of transsexual women should carefully explore patient attitudes toward self-castration and work toward improving access to elective orchiectomy to reduce the number of self-castrations and costs to the overall health care system.

1989-01-01

Quality assurance and effective nurse management can be viewed as intersecting goals. Objective feedback derived from quality assurance data is a potentially powerful means of enhancing nurses' performance and job satisfaction. The use of automated information systems to provide such direct feedback offers the additional advantage of recognizing nurses as self-monitoring, self-correcting professionals. The need, opportunity, and challenge involved in meshing quality assurance with human resource management through computer-generated feedback are discussed in the context of the home health care setting.

A Woman with Black Beads in Her Stomach: Severe Gastric Ulceration Caused by Yttrium-90 Radioembolization

Directory of Open Access Journals (Sweden)

Indu S. Voruganti

2018-01-01

Full Text Available Radioembolization (RE is a selective internal radiation therapy (SIRT delivering targeted, high-dose, intra-arterial radiation directly to the vascular supply of liver tumors. Complications can occur due to aberrant deposition or migration of radiation microspheres into nontarget locations, including normal hepatic parenchyma, lungs, pancreas, and upper gastrointestinal (UGI tract. We report a case of gastric ulcers due to yttrium-90 (90Y seed migration to the stomach to alert clinicians to this rare cause of gastric injury. A 57-year-old woman with stage IV breast cancer with liver and lung metastases presented to the hospital with 2 months of worsening nausea and vomiting. Two months prior, she had received SIRT with 90Y microspheres without complications. Upper GI endoscopy showed diffuse gastritis and extensive antral ulceration. Biopsies revealed black, spherical foreign bodies, consistent with 90Y microspheres, documenting radiation injury. Radiation-induced UGI ulceration is caused by direct radiation injury from beta-radiation. Delay in diagnosis may be due to the nonspecificity of symptoms and temporal delay of symptom onset from SIRT, which was 2 months in our patient. Also, complaints may be attributed erroneously to adjuvant chemotherapy or widespread metastatic disease. Clinicians must consider radiation-associated toxicity in any SIRT-treated patient developing abdominal symptoms.

David Herbert Lawrence is one of the greatest novelists in the 20th century. In his novels, he portrays various types of women characters. Ursula Brangwen is a quintessential modern woman in The Rainbow and she shows the important characteris-tics of the western modern women. Being different from the traditional women, She is a rebelling woman and does not want to be bounded by conventions. She dares to condemn the religion, the Education system and the democracy. What's more, she pur-sues knowledge and freedom and strives for the value of self-realization, independence and individualism.

Self-reported physical activity among blacks: estimates from national surveys.

Whitt-Glover, Melicia C; Taylor, Wendell C; Heath, Gregory W; Macera, Caroline A

2007-11-01

National surveillance data provide population-level estimates of physical activity participation, but generally do not include detailed subgroup analyses, which could provide a better understanding of physical activity among subgroups. This paper presents a descriptive analysis of self-reported regular physical activity among black adults using data from the 2003 Behavioral Risk Factor Surveillance System (n=19,189), the 2004 National Health Interview Survey (n=4263), and the 1999-2004 National Health and Nutrition Examination Survey (n=3407). Analyses were conducted between January and March 2006. Datasets were analyzed separately to estimate the proportion of black adults meeting national physical activity recommendations overall and stratified by gender and other demographic subgroups. The proportion of black adults reporting regular PA ranged from 24% to 36%. Regular physical activity was highest among men; younger age groups; highest education and income groups; those who were employed and married; overweight, but not obese, men; and normal-weight women. This pattern was consistent across surveys. The observed physical activity patterns were consistent with national trends. The data suggest that older black adults and those with low education and income levels are at greatest risk for inactive lifestyles and may require additional attention in efforts to increase physical activity in black adults. The variability across datasets reinforces the need for objective measures in national surveys.

We check the consistency of the entropy of Bardeen and Ayón Beato-García-Bronnikov black holes with the entropy of particular conformal field theory via Cardy-Verlinde formula. We also compute the first-order semiclassical corrections of this formula due to self-gravitational effects by modifying pure extensive and Casimir energy in the context of Keski-Vakkuri, Kraus and Wilczek analysis. It is concluded that the correction term remains positive for both black holes, which leads to the violation of the holographic bound

Feederism in a woman.

2011-06-01

Feederism is a fat fetish subculture in which individuals eroticize weight gain and feeding. Feeders are individuals who claim to become sexually aroused by feeding their partners and encouraging them to gain weight. Conversely, Feedees are individuals who claim to become sexually aroused by eating, being fed, and the idea or act of gaining weight. Very little is known about this population. This report describes a woman who self-identified as a Feedee. It is unclear, at present, whether female Feederism represents a unique paraphilia or a thematic variation of morphophilia or sexual masochism.

On the runaway instability of self-gravitating torus around black holes

International Nuclear Information System (INIS)

Font, Jose A; Montero, Pedro J; Shibata, Masaru

2010-01-01

Black holes surrounded by self-gravitating tori are astrophysical systems which may naturally form following the core collapse of a massive star or the merger of two neutron stars. We present here results from fully general relativistic numerical simulations of such systems in order to assess the influence of the torus self-gravity on the onset of the so-called runaway instability. This instability, which might drive the rapid accretion of the disk on shorter timescales than those required to power a relativistic fireball, potentially challenges current models of gamma-ray bursts. Our simulations indicate that the self-gravity of the torus does not actually favour the onset of the instability.

Specifically, the paper aimed to answer the following questions: (1 How are female protagonists depicted in the selected short stories written by Filipino woman authors? What are their virtues, vices, passions, and struggles?; and (2 What roles do these female protagonists play in the Philippine society? A virtue displayed by the most female characters is having a sense of responsibility. Most of the woman characters are passionate in preserving their relationship with their loved ones or keeping the peace among the family members. The Filipino woman, in the short stories, has projected varied images which could be categorized as martyr, social victim, homemaker, mother, and fighter. The Filipino woman is a product of her time and milieu – heterogeneous in looks, psyche, and roles in the society.

Applying the Stress and ‘Strength’ Hypothesis to Black Women’s Breast Cancer Screening Delays

Science.gov (United States)

Black, Angela Rose; Woods-Giscombé, Cheryl

2013-01-01

Associations between stress and breast cancer highlight stressful life events as barriers to breast cancer screening, increased stress due to a breast cancer scare or diagnosis, or the immunosuppressive properties of stress as a risk factor for breast cancer occurrence. Little is known, however, about how women’s reactions to stressful life events impact their breast health trajectory. In this study, we explore how reactions to stressors serve as a potential barrier to breast cancer screening among Black women. We apply a gender-specific, culturally responsive stress-process framework, the Stress and ‘Strength’ Hypothesis (“strength hypothesis”), to understand links between the ‘Strong Black Woman role’ role, Black women’s stress reactions and their observed screening delays. We conceptualize strength as a culturally prescribed coping style that conditions resilience, self-reliance and psychological hardiness as a survival response to race-related and gender-related stressors. Using qualitative methods, we investigate the potential for this coping mechanism to manifest as extraordinary caregiving, emotional suppression and self-care postponement. These manifestations may result in limited time for scheduling and attending screening appointments, lack of or delay in acknowledgement of breast health symptoms and low prioritization of breast care. Limitations and future directions are discussed. PMID:23129558

The Association of Minority Self-Rated Health with Black versus White Gentrification.

Science.gov (United States)

Gibbons, Joseph; Barton, Michael S

2016-12-01

There exists controversy as to the impact gentrification of cities has on the well-being of minorities. Some accuse gentrification of causing health disparities for disadvantaged minority populations residing in neighborhoods that are changing as a result of these socioeconomic shifts. Past scholarship has suggested that fears of displacement and social isolation associated with gentrification lead to poorer minority health. However, there is a lack of research that directly links gentrification to minority health outcomes. We address this gap with individual data from the 2008 Philadelphia Health Management Corporation's Southeastern Pennsylvania Household Health Survey and census tract data from the 2000 Decennial Census and the 2006-2010 American Community Survey. We implement logistic multilevel models to determine whether and how a resident's self-rated health is affected by gentrification of their neighborhoods. We find that while gentrification does have a marginal effect improving self-rated health for neighborhood residents overall, it leads to worse health outcomes for Blacks. Accounting for racial change, while gentrification leading to increases in White population has no measurable effect on minority health, "Black gentrification" leads to marginally worse health outcomes for Black respondents. These results demonstrate the limitations that improvements of neighborhood socioeconomic character have in offsetting minority health disparities.

Representin' in cyberspace: sexual scripts, self-definition, and hip hop culture in Black American adolescent girls' home pages.

Science.gov (United States)

Stokes, Carla E

2007-01-01

Despite the importance of media in the lives of girls, sexuality researchers have largely overlooked how Black American adolescent girls engage with media to construct sexual self-definitions and explore their emerging sexuality. This study investigated sexual scripts, self-definition, and hip hop culture in internet home pages constructed by Black girls aged 14-17 years residing in southern states in the USA. Although some girls in the sample constructed sexual self-representations that mirrored sexual scripts portrayed in the media, hip hop, and youth cyberculture, others resisted stereotypical representations of Black female sexuality. This paper discusses the dominant sexual scripts that emerged from in-depth analysis of 27 home pages constructed by girls residing in Georgia. The focus is on 'Freaks', 'Virgins', 'Down-Ass Chicks/Bitches', 'Pimpettes', and Resisters. Findings suggest that a one-size-fits-all approach to sexuality education may fail to address key contextual issues of relevance to girls and young women. Innovative sexuality and media education strategies that respond to the significance of media in the lives of Black American girls and young women are needed.

Little information is available to inform clinical assessments on risk of self-harm repetition in ethnic minority groups. In a prospective cohort study, using data collected from six hospitals in England for self-harm presentations occurring between 2000 and 2007, we investigated risk factors for repeat self-harm in South Asian and Black people in comparison to Whites. During the study period, 751 South Asian, 468 Black and 15,705 White people presented with self-harm in the study centres. Repeat self-harm occurred in 4379 individuals, which included 229 suicides (with eight of these fatalities being in the ethnic minority groups). The risk ratios for repetition in the South Asian and Black groups compared to the White group were 0.6, 95% CI 0.5-0.7 and 0.7, 95% CI 0.5-0.8, respectively. Risk factors for repetition were similar across all three groups, although excess risk versus Whites was seen in Black people presenting with mental health symptoms, and South Asian people reporting alcohol use and not having a partner. Additional modelling of repeat self-harm count data showed that alcohol misuse was especially strongly linked with multiple repetitions in both BME groups. Ethnicity was not recorded in a third of cases which may introduce selection bias. Differences may exist due to cultural diversity within the broad ethnic groups. Known social and psychological features that infer risk were present in South Asian and Black people who repeated self-harm. Clinical assessment in these ethnic groups should ensure recognition and treatment of mental illness and alcohol misuse. Copyright © 2012 Elsevier B.V. All rights reserved.

Self-similar cosmological solutions with dark energy. II. Black holes, naked singularities, and wormholes

International Nuclear Information System (INIS)

Maeda, Hideki; Harada, Tomohiro; Carr, B. J.

2008-01-01

We use a combination of numerical and analytical methods, exploiting the equations derived in a preceding paper, to classify all spherically symmetric self-similar solutions which are asymptotically Friedmann at large distances and contain a perfect fluid with equation of state p=(γ-1)μ with 0<γ<2/3. The expansion of the Friedmann universe is accelerated in this case. We find a one-parameter family of self-similar solutions representing a black hole embedded in a Friedmann background. This suggests that, in contrast to the positive pressure case, black holes in a universe with dark energy can grow as fast as the Hubble horizon if they are not too large. There are also self-similar solutions which contain a central naked singularity with negative mass and solutions which represent a Friedmann universe connected to either another Friedmann universe or some other cosmological model. The latter are interpreted as self-similar cosmological white hole or wormhole solutions. The throats of these wormholes are defined as two-dimensional spheres with minimal area on a spacelike hypersurface and they are all nontraversable because of the absence of a past null infinity

The Einstein-Maxwell equations with a negative cosmological constant Λ in 2 + 1 spacetime dimensions discussed by Banados, Teitelboim and Zanelli are solved by assuming a self (anti-self) dual equation E r-circumflex = ± B -circumflex , which is imposed on the orthonormal basis components of the electric field E r-circumflex and the magnetic field B -circumflex . This solution describes an electrically charged extra black hole with mass M=8πGQ 2 e , angular momentum J = ±8πGQ 2 e / modul Λ 1/2 and electric charge Q e . Although the coordinate components of the electric field E r and the magnetic field B have singularities on the horizon at r (4πGQ 2 e / modul Λ) 1/2 , the spacetime has the same value of constant negative curvature R = 6Λ as that of Banados et al.

Westaway, M S; Wolmarans, L

1992-11-01

One hundred black hospitalized tuberculosis (TB) patients (75 males and 25 females) were interviewed to ascertain levels of depression and self-esteem. The standard of literacy for 65% of the sample was such that they were unable to complete a self-report inventory. Reliability (internal consistency) was good for the 21-item Beck Depression Inventory (BDI: r = 0.79), the 13-item shortened BDI (ABDI: r = 0.76) and the Rosenberg Self-Esteem scale (RSE: r = 0.78). There was a significant positive relationship between the BDI and the ABDI (r = 0.92, P = 0.0001). The recommended ABDI cut-off scores established no depression for 32 patients, mild depression for 22 patients, moderate depression for 38 patients and severe depression for 8 patients. There were significant negative relationships between the BDI and the RSE (r = -0.54, P = 0.0001), and between the ABDI and the RSE (r = -0.56, P = 0.0001). Self-esteem scores dropped in accordance with category of depression, revealing that low self-esteem is a characteristic feature of depression. It was concluded that the ABDI was a reliable, rapid, initial screening device for depression in black persons with low literacy levels.

Quality assurance in NDT

2010-01-01

The importance of Nondestructive Testing (NDT) as a Quality Control/Quality Assurance tool in the industrial domain cannot be over-emphasized. With the rapid advancement in research and technology, the NDT field is becoming larger and more sophisticated day by day. Innovative research in materials science and digital technology is paving the way for more and more new methods in NDT technology. Although the NDT technology has improved over the years, the basic 'human factor' underlying the success of the NDT field remains the same. There are two major factors that influence the 'Quality Assurance in NDT'. First, knowledgeable and skilled NDT Operators are the most important factor in assuring the reliable test results. Second, the Management oversight of the NDT operations plays a major role in assuring the overall quality of NDT. Management responsibilities include the implementation of a Quality Management System (QMS) that focuses on the NDT operations and apply all the elements of Quality Assurance relevant to NDT. Whether the NDT operations are performed in-house or by a contractor, periodic Management Self-assessments should include the following question: How can the Management assess and improve the 'Quality Assurance in NDT'? This paper attempts to answer the above question. Some practical examples are provided to illustrate the potential quality incidents that could lead to costly failures, and the role of NDT Operator and the Management in preventing such quality incidents. Also, some guidelines are provided on how the Management can apply the elements of Quality Assurance to NDT in order to assess and improve the 'Quality Assurance in NDT'. (author)

For a self-gravitating particle of mass μ in orbit around a Kerr black hole of mass M ≫ μ, we compute the O(μ/M) shift in the frequency of the innermost stable circular equatorial orbit due to the conservative piece of the gravitational self-force acting on the particle. Our treatment is based on a Hamiltonian formulation of the dynamics in terms of geodesic motion in a certain locally defined effective smooth spacetime. We recover the same result using the so-called first law of binary black-hole mechanics. We give numerical results for the innermost stable circular equatorial orbit frequency shift as a function of the black hole's spin amplitude, and compare with predictions based on the post-Newtonian approximation and the effective one-body model. Our results provide an accurate strong-field benchmark for spin effects in the general-relativistic two-body problem.

Enger, J M; Howerton, D L; Cobbs, C R

1994-06-01

We investigated the relationship between three factors--internal/external locus of control, self-esteem, and parental verbal interaction--for at-risk Black male adolescents in the United States. Forty-two male students in Grades 6, 7, and 8 who had been identified by their teachers as being at risk completed the Locus of Control Scale for Children (Nowicki & Strickland, 1973), the Self-Esteem Inventory (Coopersmith, 1967), and the Verbal Interaction Questionnaire (Blake, 1991). A moderate positive relationship found between self-esteem and parental verbal interaction was consistent with a previous finding for White high school students. A moderate negative relationship found between locus of control and self-esteem differed from a previous finding of no significant relationship for Black elementary children. A weak, yet significant, negative relationship was found between locus of control and parental verbal interaction.

"STEMulating" success factors: An investigation of the academic talents of successful Black male college graduates from STEM programs

Science.gov (United States)

Hendricks, Jill T.

This phenomenological research study explored the contributing factors experienced by Black males that epitomized their academic success in a STEM (Science, Technology, Engineering, and Mathematics) area of study. During this investigative project, eleven Black male students were interviewed to determine how they were able to successfully navigate and complete a STEM degree. The data was collected through a qualitative inquiry, which involved interviewing students and collecting the data and organizing their perspectives into common themes. The principal findings in this study suggest that Black males can excel when primary influential people establish high expectations and believe and encourage Black males to succeed by providing the essential educational support models requisite to warrant success; the Black male maintains and affirms a self-assured self-worth in himself; the Black male is exposed to these fields and professions early on in their educational quest to enable them to witness first hand powerful and productive opportunities and pathways to academic success; exposure to other Black successful male role models who can mentor and show positive proof that with effort, these fields can become a reality; increase in academic motivation and recommendations from educators and counselors who direct and guide students into and away from these rigorous career fields. An analysis of the students' individual stories gave a revealing look into the pathways of their consciousness, emotional growth, and perspectives about being a successful STEM major. This kind of insight can be a constructive diagnostic tool for students, educators, counselors, and administrators who want to motivate and influence future students to major in STEM fields of study.

In the era of ambitious HIV targets, novel HIV testing models are required for hard-to-reach groups such as men, who remain underserved by existing services. Pregnancy presents a unique opportunity for partners to test for HIV, as many pregnant women will attend antenatal care (ANC). We describe the views of pregnant women and their male partners on HIV self-test kits that are woman-delivered, alone or with an additional intervention. A formative qualitative study to inform the design of a multi-arm multi-stage cluster-randomized trial, comprised of six focus group discussions and 20 in-depth interviews, was conducted. ANC attendees were purposively sampled on the day of initial clinic visit, while men were recruited after obtaining their contact information from their female partners. Data were analysed using content analysis, and our interpretation is hypothetical as participants were not offered self-test kits. Providing HIV self-test kits to pregnant women to deliver to their male partners was highly acceptable to both women and men. Men preferred this approach compared with standard facility-based testing, as self-testing fits into their lifestyles which were characterized by extreme day-to-day economic pressures, including the need to raise money for food for their household daily. Men and women emphasized the need for careful communication before and after collection of the self-test kits in order to minimize the potential for intimate partner violence although physical violence was perceived as less likely to occur. Most men stated a preference to first self-test alone, followed by testing as a couple. Regarding interventions for optimizing linkage following self-testing, both men and women felt that a fixed financial incentive of approximately USD$2 would increase linkage. However, there were concerns that financial incentives of greater value may lead to multiple pregnancies and lack of child spacing. In this low-income setting, a lottery incentive was

The Woman in Red: Examining the Effect of Ovulatory Cycle on Women's Perceptions of and Behaviors Toward Other Women.

Science.gov (United States)

Netchaeva, Ekaterina; Kouchaki, Maryam

2018-04-01

Previous research has shown that during her monthly peak fertile window, a woman competes with other women for a suitable mate. Drawing upon research on ovulation and socially constructed meanings of the color red, we examine how a woman's fertility status and red clothing worn by a target woman change perceptions of the target, as well as behaviors toward the target. Following previous research on the ovulatory status and color red effects, we rely on both hormonal and self-reported fertility data. Across six studies, our research fails to provide support for the prediction that an ovulating woman is less likely to trust another woman wearing red compared with a nonovulating woman.

Ecological context of the evolution of self-pollination in Clarkia xantiana: population size, plant communities, and reproductive assurance.

Science.gov (United States)

Moeller, David A; Geber, Monica A

2005-04-01

The repeated evolutionary transition from outcrossing to self-pollination in flowering plants has been suggested to occur because selfing provides reproductive assurance. Reports from biogeographical and ecological surveys indicate that selfing taxa are often associated with stressful and ephemeral environments, situations in which plant abundance is low (e.g., Baker's law) and with novel plant communities, however experimental tests of ecological hypotheses are few. In this study, we examined the ecological context of selection on mating system traits (herkogamy and protandry) in a California annual, Clarkia xantiana, where natural selfing populations differ from outcrossing populations in that they are often of small size or low density and occur mainly outside the range of pollinator-sharing congeners. We constructed artificial populations of plants with broad genetic variation in floral traits and manipulated two ecological factors, plant population size, and the presence versus absence of pollinator-sharing congeners, in the center of the geographic range of outcrossing populations. We found evidence for context-dependent selection on herkogamy and protandry via female fitness in which reduced traits, which promote autonomous selfing, were favored in small populations isolated from congeners whereas selection was comparatively weak in large populations or when congeners were present. In small, isolated populations, the fertility of plants with low herkogamy or protandry was elevated by 66% and 58%, respectively, compared to those with high herkogamy or protandry. The presence of pollinator-sharing congeners augmented bee visitation rates to C. xantiana flowers by 47% for all bees and by 93% for pollen specialists. By facilitating pollinator visitation, congeners mitigated selection on mating system traits in small populations, where outcross mating success is often low (the Allee effect). We also found support for the hypothesis that pollinator availability

GRAY CNVUFAC, Black-Body Radiation View Factors with Self-Shadowing

International Nuclear Information System (INIS)

Wong, R.L.

1991-01-01

Description of program or function: CNVUFAC, the General Dynamics heat-transfer radiation view program, was adapted for use on the LLNL computer system. The input and output were modified, and a node incrementing logic added for compatibility with TRUMP (NESC 771) thermal analyzer and related codes. The program performs the multiple integration necessary to evaluate the geometric black-body radiation node to node view factors. CNVUFAC uses an elemental area summation scheme to evaluate the multiple integrals. The program permits shadowing and self-shadowing. The basic configuration shapes that can be considered are cylinders, cones, spheres, ellipsoids, flat plates, disks, toroids, and polynomials of revolution. Portions of these shapes can also be considered. Card-image output containing node number and view factor information is generated for input to GRAY, a related code. GRAY performs the matrix manipulations necessary to convert black-body radiation heat-transfer view factors to gray-body view factors as required by thermal analyzer codes. The black-body view factors contain only geometric relationships. GRAY allows the effects of multiple gray-body reflections to be included. The resulting effective gray-body view factors can then be used with the corresponding fourth-power temperature differences to obtain the net radiative heat flux. GRAY accepts a matrix input or the card-image output generated by CNVUFAC. The resulting card-image GRAY output is in a form usable by TRUMP

Woods, N F; Lentz, M; Mitchell, E; Oakley, L D

During the last two decades, investigators have explored the relationship between women's life conditions and their mental health. Some have related women's socially disadvantaged status, or their socialization to a traditional feminine role, to depression and low self-esteem. Others have emphasized the consequences of women's roles, or the balance of social demands and resources, on their well-being. More recently, feminist scholars have proposed a developmental account of depression. We tested a model comparing the effects of personal resources, social demands and resources, socialization, and women's roles, on self-esteem and depressed mood in young adult Asian, Black, and White women in America. Women who resided in middle-income and racially mixed neighborhoods were interviewed in their homes. Personal resources were indicated by education and income and social resources by unconflicted network size as measured by Barrera's (1981) Arizona Social Support Interview Schedule. Social demands were assessed by conflicted network size as measured by the Barrera scale and by the Positive Life Events and Negative Life Events scales from Norbeck's (1984) revision of the Sarason Life Events Scale. Women's roles included employment, parenting, and partnership with an adult (e.g., marriage). Self-esteem was assessed with the Rosenberg Self Esteem Scale (Rosenberg, 1965) and depressed mood with the Center for Epidemiologic Studies Depression scale (Radloff, 1977). Although models for Asian, Black, and White women differed, social network and social demands as well as personal resources were common to each group as predictors of self-esteem and depression.

Income and Self-Rated Mental Health: Diminished Returns for High Income Black Americans

Directory of Open Access Journals (Sweden)

Shervin Assari

2018-05-01

Full Text Available Background: The minorities’ diminished return theory suggests that socioeconomic position (SEP generates smaller health gains for racial/ethnic minorities compared to Whites. The current study was a Black–White comparison of the association between household income and self-rated mental health (SRMH. Methods: This cross-sectional study used data from the 2017 State of the State Survey (SOSS. With representative sampling, the SOSS generates results that are generalizable to the state of Michigan. This study included 881 adults, (n = 92 Black and (n = 782 White. The independent variable was household income. The dependent variable was SRMH, measured using a single item. Age, gender, and participation in the labor force were covariates. Race/ethnicity was the focal moderator. Logistic regression models were used for data analysis. Results: Overall, higher household income was associated with better SRMH, net of covariates. An interaction was found between race/ethnicity and household income on SRMH, suggesting a smaller, or nonexistent, protective effect for Blacks compared to Whites. In race/ethnicity-stratified models, higher household income was associated with better SRMH for Whites but not Blacks. Conclusion: Supporting the minorities’ diminished return theory, our study documents differential effects for income on SRHM for Blacks and Whites, where Whites but not Blacks appear to benefit from their income. Given this, researchers and policy makers are cautioned against making assumptions that racial groups benefit equally from similar economic resources.

The self-force on a non-minimally coupled static scalar charge outside a Schwarzschild black hole

International Nuclear Information System (INIS)

Cho, Demian H J; Tsokaros, Antonios A; Wiseman, Alan G

2007-01-01

The finite part of the self-force on a static, non-minimally coupled scalar test charge outside a Schwarzschild black hole is zero. This result is determined from the work required to slowly raise or lower the charge through an infinitesimal distance. Unlike similar force calculations for minimally-coupled scalar charges or electric charges, we find that we must account for a flux of field energy that passes through the horizon and changes the mass and area of the black hole when the charge is displaced. This occurs even for an arbitrarily slow displacement of the non-minimally coupled scalar charge. For a positive coupling constant, the area of the hole increases when the charge is lowered and decreases when the charge is raised. The fact that the self-force vanishes for a static, non-minimally coupled scalar charge in Schwarzschild spacetime agrees with a simple prediction of the Quinn-Wald axioms. However, Zel'nikov and Frolov computed a non-vanishing self-force for a non-minimally coupled charge. Our method of calculation closely parallels the derivation of Zel'nikov and Frolov, and we show that their omission of this unusual flux is responsible for their (incorrect) result. When the flux is accounted for, the self-force vanishes. This correction eliminates a potential counter example to the Quinn-Wald axioms. The fact that the area of the black hole changes when the charge is displaced brings up two interesting questions that did not arise in similar calculations for static electric charges and minimally coupled scalar charges. (1) How can we reconcile a decrease in the area of the black hole horizon with the area theorem which concludes that δArea horizon ≥ 0? The key hypothesis of the area theorem is that the stress-energy tensor must satisfy a null-energy condition T αβ l α l β ≥ 0 for any null vector l α . We explicitly show that the stress-energy associated with a non-minimally coupled field does not satisfy this condition, and this violation of

To evaluate if improvements in the quality of diabetes care in Indian clinics can be obtained by simple self-surveillance PC-based software. Nineteen Indian diabetes clinics were introduced to the principles of quality assurance (QA), and to a software program, the Steno Quality Assurance Tool (SQAT). Data was entered for an initial 3 months period. Subsequently data were analyzed by the users, who designed plans to improve indicator status and set goals for the upcoming period. A second data entry period followed after 7-9 months. QA data was analyzed from 4487 T2DM patients (baseline) and 4440 (follow-up). The average examination frequency per clinic of the following indicators increased significantly: lipid examination (72-87%) (p=0.007), foot examination (80-94%) (p=0.02), HbA1c investigation (59-77%) (p=0.006), and urine albumin excretion investigation (72-87%) (p=0.006). Outcome parameters also improved significantly: mean (SD) fasting and post prandial BG reduced from 144(16) to 132(16)mg/dl (p=0.02) and 212(24)-195(29)mg/dl (p=0.03), respectively. Systolic BP reduced from 139(6) to 133(4) (p=0.0008)mmHg and diastolic BP from 83(3) to 81(3)mmHg (p=0.002). Quality of diabetes care can be improved by applying SQAT, a QA self-surveillance software that enables documentation of changes in process and outcome indicators.

Quality assurance in the structural installations of nuclear power stations

International Nuclear Information System (INIS)

Schnellenbach, G.; Wrage, S.

1985-01-01

The concept of quality assurance distinguishes between self-monitoring of the design, manufacturing and executing firms and external monitoring by state institutions or by experts commissioned by them. The long-term control of structures is within the area of responsibility of the owner. This quality assurance concept is controlled in detail by statutes, which clearly define responsibilities. This structural engineering quality assurance system also forms the basis for the design, construction and utilization of structural installations of nuclear power stations; requirements emanating from the Atomic Energy Acts for the structural installations demand, however, to some extent a sharpening of self- and external monitoring. Therefore, today a quality concept has been developed for the important engineering safety-related buildings of nuclear power stations. This concept takes account of the strict requirements imposed and fulfils the requirement of KTA 1401. (orig.) [de

Gubbels, Nanda P; Sijbrand, Merijn H; Onstenk, Ron

2014-01-01

Alkaptonuria is a rare metabolic disorder due to a defect in the gene for homogentisic acid oxidase. This results in an accumulation of homogentisic acid, which leads to the deposit of pigment in the connective tissue in the body. This causes problems and symptoms in various organ systems, such as early artropathy, dark-coloured urine, black sclerae, dark-coloured aortic valves and an increased risk of kidney stones and gall stones. Various specialists may see patients with this disease. The diagnosis is often missed. We describe a 69-year-old woman who underwent surgery due to joint problems, which showed up black cartilage. It turned out that for many years she had also had eye and heart problems. Not until later in life was she diagnosed with alkaptonuria. There is no curative treatment for alkaptonuria at the moment. Early recognition of the disease can increase the quality of life. Preventative check-ups and guidance are also therefore necessary.

DOE Order 5700.6C, Quality Assurance, stipulates QA requirements for all DOE activities. This order is now codified as 10CFR830.120, Nuclear Safety Management, Quality Assurance Requirements, which is applicable to DOE nuclear facilities. A Quality Assurance Management Plan (QAMP) was developed by the Health Physics Operations Group (ESH-1) at Los Alamos National Laboratory (LANL). The goal of the ESH-1 QAMP is to ensure that operational radiation protection activities meet the criteria outlined in DOE Order 5700.6C, DOE-ER-STD-6001-92 and 10CFR830.120. The ten required elements are QA Program, Personal Training and Qualifications, Quality Improvement, Documents and Records, Work Processes, Design, Procurement, Inspection and Acceptance Testing, Management Assessment and Independent Assessment. The QAMP has been useful for the development of QAMPs at nuclear facilities and has helped ensure uniformity of institutional requirements where Health Physics services are deployed to facilities. To implement a subset of QAMP requirements, a Quality Assurance Self-Evaluation Program (QASE) was established. This program provides a novel self-audit mechanism for the formal identification and correction of non-conforming items related to Operational Health Physics. Additionally, the QASE is a useful management tool for Radiological Control Technician Supervisors and staff and provides a tracking mechanism for ongoing problem areas. Data have been Collected for two calendar years on a number of concerns that fall into four general categories: radiological posting and labeling, instrumentation, monitoring requirements, and radiological documents/records

Nuclear quality assurance operating philosophy: A quality-oriented approach

1992-01-01

Quality assurance programs have been part of the nuclear utility management process since the publication of the draft of 10CFR50 Appendix B in the late 1960s. The unwritten operational philosophy of nuclear quality assurance organizations focused on compliance with federal regulations. Adverse experiences, including operational events and extended shutdowns, prompted the gradual adoption of isolated practices extending beyond compliance orientation. These practices have an orientation that accommodates a definition of quality, a perspective of the role of nuclear quality assurance organizations in the overall concept of defense-in-depth, a definition of the segments of the nuclear quality assurance mission, and recent advances in the understanding of self-assessment. Observation of these practices at various nuclear utilities resulted in a syntheses of practices and approaches into a coherent quality-oriented nuclear quality assurance operating philosophy that is not totally adopted at any one utility

Self-Esteem, Locus of Control, and First-Time NCLEX-RN Passage of BSN Students at Historically Black Colleges and Universities.

Chavis, Pamella Ivey

Relationships between self-esteem, locus of control (LOC), and first-time passage of National Council Licensure Examination for Registered Nurses (NCLEX-RN®) were examined at baccalaureate nursing programs at two historically black colleges and universities. Shortages continue to exceed demands for RNs prepared at the baccalaureate level. Inconsistent pass rates on the NCLEX-RN for graduates of historically black colleges and universities impede the supply of RNs. Surveys and archival data were used to examine characteristics of the sample and explore relationships among variables. All participants (N = 90) reported high self-esteem and internal LOC. Models suggested that all those with high self-esteem and internal LOC would pass the NCLEX-RN; only 85 percent passed the first time. Statistical analysis revealed a lack of statistical significance between self-esteem, LOC, and first-time passage. Variables not included in the study may have affected first-time passage.

We examined differences in self-reported mental health (SRMH) between US-born and Somalia-born Black Americans compared with White Americans. We tested how SRMH was affected by stigma toward seeing a mental health provider, discrimination in the health care setting, or symptoms of depression. Data were from a 2008 survey of adults in Minnesota and were limited to US-born and Somalia-born Black and White Americans (n = 938). Somalia-born adults were more likely to report better SRMH than either US-born Black or White Americans. They also reported lower levels of discrimination (18.6%) than US-born Black Americans (33.4%), higher levels of stigma (23.6% vs 4.7%), and lower levels of depressive symptoms (9.1% vs 31.6%). Controlling for stigma, discrimination, and symptomatology, Somalia-born Black Americans reported better SRMH than White and Black Americans (odds ratio = 4.76). Mental health programming and health care providers who focus on Black Americans' mental health might be missing important sources of heterogeneity. It is essential to consider the role of race and ethnicity, but also of nativity, in mental health policy and programming.

Black Adolescent Males: Intersections Among Their Gender Role Identity and Racial Identity and Associations With Self-Concept (Global and School).

Science.gov (United States)

Buckley, Tamara R

2017-09-12

Intersectional approaches for understanding identity have gained momentum in the social sciences. Black adolescent males are often perceived as threatening, underachieving, and hypermasculine, which is reinforced through media outlets and psychological research that portray them as a monolith rather than a heterogeneous group with multiple intersecting identities. This cross-sectional study of 70 Black adolescent males between 14 and 18 years old simultaneously explores their race and gender identities and associations with self-concept (global and school). Results demonstrated that participants reported a combination of feminine and masculine gender roles, rather than hypermasculine. A canonical correlation analysis found that Black racial identity attitudes (RIAS-L) and gender roles simultaneously contributed to significant relationships with total and school self-concept. Study limitations and future directions for research and practice are discussed. © 2017 The Authors. Child Development © 2017 Society for Research in Child Development, Inc.

Complete genome sequence and lifestyle of black-pigmented Corynebacterium aurimucosum ATCC 700975 (formerly C. nigricans CN-1 isolated from a vaginal swab of a woman with spontaneous abortion

Full Text Available Abstract Background Corynebacterium aurimucosum is a slightly yellowish, non-lipophilic, facultative anaerobic member of the genus Corynebacterium and predominantly isolated from human clinical specimens. Unusual black-pigmented variants of C. aurimucosum (originally named as C. nigricans continue to be recovered from the female urogenital tract and they are associated with complications during pregnancy. C. aurimucosum ATCC 700975 (C. nigricans CN-1 was originally isolated from a vaginal swab of a 34-year-old woman who experienced a spontaneous abortion during month six of pregnancy. For a better understanding of the physiology and lifestyle of this potential urogenital pathogen, the complete genome sequence of C. aurimucosum ATCC 700975 was determined. Results Sequencing and assembly of the C. aurimucosum ATCC 700975 genome yielded a circular chromosome of 2,790,189 bp in size and the 29,037-bp plasmid pET44827. Specific gene sets associated with the central metabolism of C. aurimucosum apparently provide enhanced metabolic flexibility and adaptability in aerobic, anaerobic and low-pH environments, including gene clusters for the uptake and degradation of aromatic amines, L-histidine and L-tartrate as well as a gene region for the formation of selenocysteine and its incorporation into formate dehydrogenase. Plasmid pET44827 codes for a non-ribosomal peptide synthetase that plays the pivotal role in the synthesis of the characteristic black pigment of C. aurimucosum ATCC 700975. Conclusions The data obtained by the genome project suggest that C. aurimucosum could be both a resident of the human gut and possibly a pathogen in the female genital tract causing complications during pregnancy. Since hitherto all black-pigmented C. aurimucosum strains have been recovered from female genital source, biosynthesis of the pigment is apparently required for colonization by protecting the bacterial cells against the high hydrogen peroxide concentration in

"Less than a Vapor": Positioning Black lesbian women in history teacher education.

Science.gov (United States)

Woodson, Ashley N

2017-10-02

In this article, I discuss the possibilities and implications of centering Black lesbian identities and relationships in history teacher education through a case study with one straight Black woman preservice history teacher named Danitra. Danitra's understanding and navigation of historical research on Black lesbians are discussed in relation to core themes of lesbian historiography and emancipatory historiography. Though the literature on this group is limited, I argue that critical considerations of Black lesbians' interests and experiences help educators to conceive of and teach about history, citizenship, justice, and sexuality in more liberatory ways. I conclude by offering recommendations to history teachers and teacher educators who hope to draw on lesbian and emancipatory historiographies to challenge discourses of invisibility in history teacher education classrooms.

"Machismo," self-esteem, education and high maximum drinking among anglo, black and Mexican-American male drinkers.

Neff, J A; Prihoda, T J; Hoppe, S K

1991-09-01

This study seeks to clarify the relevance of machismo to patterns of high maximum drinking among male drinkers. Specifically, the study describes the psychometric properties of a newly developed 7-item machismo measure, compares levels of machismo and self-esteem for a sample of Anglo, black and Mexican-American males, and examines both main and interaction effects of machismo, self-esteem and education as predictors of alcohol use in these racial/ethnic subgroups. Logistic regression analyses document interaction between race/ethnicity, machismo, self-esteem and education, which calls into question the presumed importance of machismo as a cultural element causing heavy drinking patterns among Mexican-American males.

Wading through the stereotypes: positive and negative associations between media use and black adolescents' conceptions of self.

Science.gov (United States)

Ward, L Monique

2004-03-01

Although concern is often expressed that frequent media exposure may adversely affect the self-esteem and racial self-esteem of African American youths, evidence to support this assumption has been limited. To examine this issue, the author collected data among 156 African American high school students, testing connections among racial self-esteem, three dimensions of self-esteem, and multiple forms of media use. Whereas initial comparisons revealed media use to be a negative correlate of self-esteem, further analysis demonstrated that this association varied depending on the media genre and the domain of self in question, the content of students' media diets, and the individual characteristics of the viewer. In addition, both stronger identification with popular Black characters and greater religiosity emerged as possible protective factors. ((c) 2004 APA, all rights reserved)

D.S. Sense’s “On My Detroit Everything”: Self-Articulating Black Girl Magic

Directory of Open Access Journals (Sweden)

Kellie D. Hay

2018-04-01

Full Text Available Long before the hashtag #BlackGirlMagic was popularized on social network sites Black women in Detroit have been employing art in their processes of self-articulation and efforts to deal with the complexities and challenges of life in the city. The scripts of African American women that dominate the commercial hip hop industry and their impacts on girls and women have received thorough analysis in academia; yet, the practices, representations, and discursive articulations of independent, Black women hip hop artists remain underexplored. In particular, this essay draws on Deidre “D.S. Sense” Smith’s spoken word poem “On My Detroit Everything” to illuminate the counter-narratives and scripts that Black women have been creating to document, validate, and voice their experiences at a critical point in Detroit’s history as it underwent and continues to deal with the after effects of bankruptcy. Hip hop artists who use cultural production to accomplish grass roots community-building offer alternative visions of what it means to do political work. More than a strategy, we argue that such practices serve as the foundation for a movement that is significant and worthy of documentation in the contemporary neoliberal moment where in policies are accelerating the continued disenfranchisement of people of color in cities such as Detroit.

Bolivar, S.L.; Day, J.L.

1993-01-01

This paper describes the role of the quality assurance liaison, the responsibilities of this position, and the evolutionary changes in duties over the last six years. The role of the quality assurance liaison has had a very positive impact on the Los Alamos Yucca Mountain Site Characterization (YW) quality assurance program. Having both technical and quality assurance expertise, the quality assurance liaisons are able to facilitate communications with scientists on quality assurance issues and requirements, thereby generating greater productivity in scientific investigations. The quality assurance liaisons help ensure that the scientific community knows and implements existing requirements, is aware of new or changing regulations, and is able to conduct scientific work within Project requirements. The influence of the role of the quality assurance liaison can be measured by an overall improvement in attitude of the staff regarding quality assurance requirements and improved job performance, as well as a decrease in deficiencies identified during both internal and external audits and surveillances. This has resulted in a more effective implementation of quality assurance requirements

2017-07-01

Over the past decades, the decline in Black marriages and the upsurge of never-married Blacks have stimulated much theoretical focus, but researchers conducted few studies on never-married heterosexual Black adults' coupling unions. Guided by an integrated framework of Africana womanism and symbolic interactionism, this qualitative hermeneutic phenomenological study used comprehensive individual interviews to explore the experiences of 26 never-married heterosexual Black men and women between the ages 25 and 35 about their attempts to cultivate and maintain intimate romantic relationships as well as their desire for marriage. Findings revealed mixed emotions from participants' lived experiences in developing and sustaining romantic relationships. Clinical implications highlighted the need to effectively attend to Black romantic relationships and experiences in their sociohistorical and sociocultural contexts. © 2017 American Association for Marriage and Family Therapy.

In this study, we examined the factor structure of the Collective Self-Esteem Scale (CSES; Luhtanen & Crocker, 1992) across 2 separate samples of Black Americans. The CSES was administered to a sample of Black American adolescents (n = 538) and a community sample of Black American adults (n = 313). Results of confirmatory factor analyses (CFAs), however, did not support the original 4-factor model identified by Luhtanen and Crocker (1992) as providing an adequate fit to the data for these samples. Furthermore, an exploratory CFA procedure failed to find a CSES factor structure that could be replicated across the 2 samples of Black Americans. We present and discuss implications of the findings.

Living an unstable everyday life while attempting to perform normality - the meaning of living as an alcohol-dependent woman.

Thurang, Anna; Bengtsson Tops, Anita

2013-02-01

To illuminate the meaning of living with alcohol dependency as a woman. The number of women suffering from alcohol dependency is increasing. Today there are shortcomings in knowledge about the lived experiences of being a woman with alcohol dependency; knowledge which might be of importance for meeting these women's specific needs of care. The study has a qualitative design. Fourteen women with alcohol dependency participated in open in-depth interviews. Data were analysed according to a phenomenological-hermeneutic method, and interpreted by help from gender and caring perspectives as well as results from previous research of alcohol dependency. In relation to the women's senses of well-being, four main gender formations were found; An unstable self involving continual and rapid swings between emotional and bodily reactions. Ambivalence - meaning ambiguous feelings towards themselves as human beings and how they lead their lives. Introspectiveness - involving reflections, pondering and being introverted. Attempts to perform normality - covering - dealing with life through various strategies and facades to live up to the expectations of how to behave as a woman. Living with alcohol dependency as a woman constitutes of a rapid shifting everyday life resulting in senses of alienation as well as private introspection leading to self-degradation, and to a lesser extent meaningfulness and hope. It also constitutes of managing to perform normality. When supporting women with alcohol dependency towards wellbeing, professionals need to work towards approaching the woman's inner thoughts, share them and reflect over them together. To support these women to find balance in life, caregivers need to cooperate with the women to find out how best to live a life adjusted to the woman's abilities and wishes. © 2012 Blackwell Publishing Ltd.

Full Text Available The study investigated the relationship between body mass index and self-concept among adolescent black female university students. The study used a mixed research design (quantitative and qualitative methods. Media images of handsome faces and beautiful bodies are used to sell almost everything, from clothes and cosmetic to luncheon, meats, and so on. These images reinforce the western cultural stereotype that women should be thin and shapely to be attractive. Thus, as some girls go through puberty they may become dissatisfied with their weight, and to a lesser extent, with their shape, thus, developing low self-concept or imae of themselves. It is in this context that the study was conceptualised.

Pride and Purpose as Antidotes to Black Homicidal Violence

Science.gov (United States)

Thomas, Charles W.

1987-01-01

The incidence of black male homicide is a major public menace. The lowest incidence of black male homicide was when the black power movement was visible and flourishing. Psychohistorical data support the contention that racial pride is an effective means for regulating intragroup tensions. In the absence of an Afrocentric orientation that promotes community power and self-determination, the need for self-reliance is eroded by value illnesses. The value orientation of the black movement supplied the pride used to obtain academic success, to reduce juvenile delinquency, and to help Afro-Americans to structure their lives for personal satisfactions. Blackness has always been about personal power and social control, but society does not allow much access to either for Afro-Americans. As a consequence, stress from racism is severe, asymptomatic, and multi-faceted. The best antidote to black homicidal violence comes from a pro-social effort based upon a self-image that gives a feeling of positive accomplishment and appreciation. Afrocentric pride promotes or enhances pro-social behavior. PMID:3560242

The Weight of a Woman's Testimony

Directory of Open Access Journals (Sweden)

Abbas Mohammad Elsiddik

2015-12-01

Full Text Available This research attempts to provide a fresh evaluation of a testimony in general and an evaluation of the weight of woman's testimony in particular. By using an empirical methodology, the research responds to the equality issue between women and men as competent witnesses, as Western jurisprudence claims, and the issue of non-equality between women and men as competent witnesses, as Islamic Sharia scholars claim. This study found numerous results, one of which was that womanhood affects a woman's ability to bear in mind a witnessed fact. Therefore, womanhood should be dealt with as a discrediting her testimony factor. Another result was that woman's testimony is admissible, even if she was alone; because womanhood is a factor relating to the weight of a testimony not a stipulation for the admissibility of testimony. Moreover, the research classified testimony in regard to its weight into two kinds. The first kind is Attestation, which always requires corroboration from a man or woman to renders it admissible as evidence. The second kind is Testimony, which does not generally require corroboration, even if the witness is a woman. However, corroboration may be necessary if the testimony has been affected by any discrediting factor regardless the sex of the witness. One more result of the research was that corroboration for testimony is affected by womanhood in certain cases, can be attained by summoning another woman as a witness, inferring factual presumptions, or examining the surrounding circumstances.

This paper explores the relationship between modernity and femininity as manifest through the women’s activity, gaze and attire in Marie al-Khazen as well as other photographs taken in the Middle East region between the 1930s and the 1940s. Al-Khazen and the women represented in the photographs of this period were part of a cosmopolitan sensibility that reveals the Middle East region to be far more international than one might have imagined. Caught between projecting a self-image of the cosmopolitan woman and one of the traditional bedouin, these photographs provide a rich field for tracking the ambiguities of the modern.

Self-organized, effective medium black silicon antireflection structures for silicon optics in the mid-infrared

Steglich, Martin; Käsebier, Thomas; Kley, Ernst-Bernhard; Tünnermann, Andreas

2016-09-01

Thanks to its high quality and low cost, silicon is the material of choice for optical devices operating in the mid-infrared (MIR; 2 μm to 6 μm wavelength). Unfortunately in this spectral region, the refractive index is comparably high (about 3.5) and leads to severe reflection losses of about 30% per interface. In this work, we demonstrate that self-organized, statistical Black Silicon structures, fabricated by Inductively Coupled Plasma Reactive Ion Etching (ICP-RIE), can be used to effectively suppress interface reflection. More importantly, it is shown that antireflection can be achieved in an image-preserving, non-scattering way. This enables Black Silicon antireflection structures (ARS) for imaging applications in the MIR. It is demonstrated that specular transmittances of 97% can be easily achieved on both flat and curved substrates, e.g. lenses. Moreover, by a combined optical and morphological analysis of a multitude of different Black Silicon ARS, an effective medium criterion for the examined structures is derived that can also be used as a design rule for maximizing sample transmittance in a desired wavelength range. In addition, we show that the mechanical durability of the structures can be greatly enhanced by coating with hard dielectric materials like diamond-like carbon (DLC), hence enabling practical applications. Finally, the distinct advantages of statistical Black Silicon ARS over conventional AR layer stacks are discussed: simple applicability to topological substrates, absence of thermal stress and cost-effectiveness.

Adherence to self-monitoring via interactive voice response technology in an eHealth intervention targeting weight gain prevention among Black women: randomized controlled trial.

eHealth interventions are effective for weight control and have the potential for broad reach. Little is known about the use of interactive voice response (IVR) technology for self-monitoring in weight control interventions, particularly among populations disproportionately affected by obesity. This analysis sought to examine patterns and predictors of IVR self-monitoring adherence and the association between adherence and weight change among low-income black women enrolled in a weight gain prevention intervention. The Shape Program was a randomized controlled trial comparing a 12-month eHealth behavioral weight gain prevention intervention to usual care among overweight and obese black women in the primary care setting. Intervention participants (n=91) used IVR technology to self-monitor behavior change goals (eg, no sugary drinks, 10,000 steps per day) via weekly IVR calls. Weight data were collected in clinic at baseline, 6, and 12 months. Self-monitoring data was stored in a study database and adherence was operationalized as the percent of weeks with a successful IVR call. Over 12 months, the average IVR completion rate was 71.6% (SD 28.1) and 52% (47/91) had an IVR completion rate ≥80%. At 12 months, IVR call completion was significantly correlated with weight loss (r =-.22; P=.04) and participants with an IVR completion rate ≥80% had significantly greater weight loss compared to those with an IVR completion rate self-monitoring. Adherence to IVR self-monitoring was high among socioeconomically disadvantaged black women enrolled in a weight gain prevention intervention. Higher adherence to IVR self-monitoring was also associated with greater weight change. IVR is an effective and useful tool to promote self-monitoring and has the potential for widespread use and long-term sustainability.

SELF-CONCEPT DIFFERENTIATION AND SELF-CONCEPT CLARITY ACROSS ADULTHOOD: ASSOCIATIONS WITH AGE AND PSYCHOLOGICAL WELL-BEING*

DIEHL, MANFRED; HAY, ELIZABETH L.

2011-01-01

This study focused on the identification of conceptually meaningful groups of individuals based on their joint self-concept differentiation (SCD) and self-concept clarity (SCC) scores. Notably, we examined whether membership in different SCD-SCC groups differed by age and also was associated with differences in psychological well-being (PWB). Cluster analysis revealed five distinct SCD-SCC groups: a self-assured, unencumbered, fragmented-only, confused-only, and fragmented and confused group. Individuals in the self-assured group had the highest mean scores for positive PWB and the lowest mean scores for negative PWB, whereas individuals in the fragmented and confused group showed the inverse pattern. Findings showed that it was psychologically advantageous to belong to the self-assured group at all ages. As hypothesized, older adults were more likely than young adults to be in the self-assured cluster, whereas young adults were more likely to be in the fragmented and confused cluster. Thus, consistent with extant theorizing, age was positively associated with psychologically adaptive self-concept profiles. This study examined whether conceptually meaningful subgroups of individuals can be identified based on their joint scores on self-concept differentiation (SCD) and self-concept clarity (SCC). Specifically, we considered whether individuals within such subgroups differed systematically from one another on measures of positive and negative psychological well-being (PWB). Of interest to us was also whether there were age differences in the distribution of adults across the SCD-SCC groups and whether age moderated the association between PWB and SCD-SCC grouping.

Analytical chemistry measurements require an installed criterion based assessment program to identify and control sources of error. This program should also gauge the uncertainty about the data. A self- assessment was performed of long established quality control practices against the characteristics of a comprehensive measurement assurance program. Opportunities for improvement were identified. This paper discusses the efforts to transform quality control practices into a complete measurement assurance program. The resulting program heightened the laboratory's confidence in the data it generated, by providing real-time statistical information to control and determine measurement quality

We present a case report on a 53-year-old transsexual woman who developed acute painless vision loss in both eyes during cross-sex hormone treatment. After 10 months of cross-sex hormone treatment, she experienced total vision loss of the right eye and, 6 months later, vision loss to 20/63 in the left eye. After a full ophthalmic exam, bilateral sequential non-arteritic ischemic optic neuropathy (NA-ION) was diagnosed. Extensive etiological work-up revealed no cardiac abnormalities or inherited blood-clotting disorders. A manifest self-administered overdose of transdermal estrogen treatment with serum estradiol levels of 5,765 pg/ml was possibly related to the sequential bilateral NA-ION resulting in nearly total vision loss in this transsexual woman.

The main efforts of Nuclear Regulatory Authority of the Slovak Republic (NRA SR) was focused on support of quality assurance programmes development at responsible organizations Bohunice V-1 and V-v and Mochovce NPPs and their inspection. Development of the level two documentation of a partial quality assurance programme for NPP operation continued at Mochovce NPP. Most of documentation has been submitted to NRA SR for comments and approval. NRA SR invited a mission of French experts to Mochovce NPP to review preparation and performance of internal audits that would be beneficial for improvement in this kind activities at the NPP. Bohunice NPP continued in development of a partial quality assurance programme for operation. The Quality Assurance Programme submitted to NRA SR for approval. Based on a request of Bohunice NPPs, NRA SR consulted the draft quality assurance programme developed by Siemens for stage of the 'Basic Design' of V-1 NPP upgrading. The programme had not been submitted for approval to NRA SR prior to completion of works by Siemens. Based on an internal audit that had been performed, corrective measures were proposed to meet requirements on review and approval of suppliers quality assurance programmes. Requirements related to the quality assurance at nuclear installations were prepared to be incorporated into principles of a act on peaceful use of nuclear power in Slovak Republic

Stereotypes of Black American Women Related to Sexuality and Motherhood

Intersectionality theorists and researchers suggest the importance of examining unique stereotypes associated with intersecting group identities. We focus on the unique stereotypes of Black women in the United States related to sexuality and motherhood. In an online experimental study, 435 undergraduates from a Northeastern U.S. university were randomly assigned to one of the four conditions in which they viewed a photograph and read a description of a target young woman. The target’s race (Black vs. White) and pregnancy status (pregnant vs. no pregnancy information) were varied. A Black female target (pregnant or not) was perceived more negatively on items related to historically rooted societal stereotypes about sexual activity, sexual risk, motherhood status, and socioeconomic status than was a White female target, but there were no differences on items unrelated to societal stereotypes. A Black target described as pregnant was also perceived as more likely to be a single mother and to need public assistance than was a White target described as pregnant. Current findings, along with evidence that societal stereotypes have damaging effects, underscore the importance of diversifying images of Black women and increasing awareness of how stereotypes affect perceptions of Black women. Findings also highlight the value of research employing intersectionality to understand stereotypes. PMID:27821904

In this paper we introduce High Assurance SPIRAL to solve the last mile problem for the synthesis of high assurance implementations of controllers for vehicular systems that are executed in today's and future embedded and high performance embedded system processors. High Assurance SPIRAL is a scalable methodology to translate a high level specification of a high assurance controller into a highly resource-efficient, platform-adapted, verified control software implementation for a given platform in a language like C or C++. High Assurance SPIRAL proves that the implementation is equivalent to the specification written in the control engineer's domain language. Our approach scales to problems involving floating-point calculations and provides highly optimized synthesized code. It is possible to estimate the available headroom to enable assurance/performance trade-offs under real-time constraints, and enables the synthesis of multiple implementation variants to make attacks harder. At the core of High Assurance SPIRAL is the Hybrid Control Operator Language (HCOL) that leverages advanced mathematical constructs expressing the controller specification to provide high quality translation capabilities. Combined with a verified/certified compiler, High Assurance SPIRAL provides a comprehensive complete solution to the efficient synthesis of verifiable high assurance controllers. We demonstrate High Assurance SPIRALs capability by co-synthesizing proofs and implementations for attack detection and sensor spoofing algorithms and deploy the code as ROS nodes on the Landshark unmanned ground vehicle and on a Synthetic Car in a real-time simulator.

Black Holes and Galactic Density Cusps II Spherically Symmetric Anisotropic Cusps

Henriksen, Richard N; Macmillan, Joseph D

2010-01-01

Aims. In this paper we study density cusps that may contain central black holes. The actual co-eval self-similar growth would not distinguish between the central object and the surroundings. Methods. To study the environment of a growing black hole we seek descriptions of steady 'cusps' that may contain a black hole and that retain at least a memory of self-similarity. We refer to the environment in brief as the 'bulge' and on smaller scales, the 'halo'. Results. We find simple descriptions of the simulations of collisionless matter by comparing predicted densities, velocity dispersions and distribution functions with the simulations. In some cases central point masses may be included by iteration. We emphasize that the co-eval self-similar growth allows an explanation of the black hole bulge mass correlation between approximately similar collisionless systems. Conclusions. We have derived our results from first principles assuming adiabatic self-similarity and either self-similar virialisation or normal stea...

If a black hole can accrete a body whose spin or charge would send the black hole parameters over the extremal limit, then a naked singularity would presumably form, in violation of the cosmic censorship conjecture. We review some previous results on testing cosmic censorship in this way using the test body approximation, focusing mostly on the case of neutral black holes. Under certain conditions a black hole can indeed be over-spun or over-charged in this approximation, hence radiative and self-force effects must be taken into account to further test cosmic censorship.

Black Holes and Galactic Density Cusps III From Black Hole to Bulge

CERN Document Server

Henriksen, Richard N; Macmillan, Joseph D

2011-01-01

Aims. In this paper we continue our study of density cusps that may contain central black holes. Methods. We recall our attempts to use distribution functions with a memory of self-similar relaxation, but mostly they apply only in restricted regions of the global system. We are forced to consider related distribution functions that are steady but not self-similar. Results. One remarkably simple distribution function that has a filled loss cone describes a bulge that transits from a near black hole domain to an outer 'zero flux' regime where$\\rho\\propto r^{-7/4}$. The transition passes from an initial inverse square profile through a region having a 1/r density profile. The structure is likely to be developed at an early stage in the growth of a galaxy. A central black hole is shown to grow exponentially in this background with an e-folding time of a few million years. Conclusions. We derive our results from first principles, using only the angular momentum integral in spherical symmetry. The initial relaxatio...

Midwives being 'with woman': An integrative review.

Bradfield, Zoe; Duggan, Ravani; Hauck, Yvonne; Kelly, Michelle

2018-04-01

Midwives being 'with woman' is embedded in professional philosophy, standards of practice and partnerships with women. In light of the centrality of being 'with woman' to the profession of midwifery, it is timely to review the literature to gain a contemporary understanding of this phenomenon. This review synthesises research and theoretical literature to report on what is known and published about being 'with woman'. A five step framework for conducting an integrative literature reviews was employed. A comprehensive search strategy was utilised that incorporated exploration in electronic databases CINAHL, Scopus, Proquest, Science Direct and Pubmed. The initial search resulted in the retrieval of 2057 publications which were reduced to 32 through a systematic process. The outcome of the review revealed three global themes and corresponding subthemes that encompassed 'with woman': (1) philosophy, incorporated two subthemes relating to midwifery philosophy and philosophy and models of care; (2) relationship, that included the relationship with women and the relationship with partners; and (3) practice, that captured midwifery presence, care across the childbirth continuum and practice that empowers women. Research and theoretical sources support the concept that being 'with woman' is a fundamental construct of midwifery practice as evident within the profession's philosophy. Findings suggest that the concept of midwives being 'with woman' is a dynamic and developing construct. The philosophy of being 'with woman' acts as an anchoring force to guide, inform and identify midwifery practice in the context of the rapidly changing modern maternity care landscapes. Gaps in knowledge and recommendations for further research are made. Copyright © 2017 Australian College of Midwives. Published by Elsevier Ltd. All rights reserved.

Orbital evolution of a test particle around a black hole: indirect determination of the self-force in the post-Newtonian approximation

International Nuclear Information System (INIS)

Burko, Lior M

2006-01-01

Comparing the corrections to Kepler's law with orbital evolution under a self-force, we extract the finite, already regularized part of the latter in a specific gauge. We apply this method to a quasi-circular orbit around a Schwarzschild black hole of an extreme mass ratio binary, and determine the first- and second-order conservative gravitational self-force in a post-Newtonian expansion. We use these results in the construction of the gravitational waveform, and revisit the question of the relative contribution of the self-force and spin-orbit coupling

Diabetes mellitus is an important public health problem that disproportionately affects minorities. Using a cross sectional, convenience sample, we estimated the prevalence of self-reported diabetes for Whites (n = 212), Arabs (n = 1,303), Chaldeans (n = 828), and Blacks (n = 789) in southeast Michigan. In addition, using a logistic regression model, we estimated odds ratios and 95% confidence intervals for the association between ethnicity and diabetes before and after adjusting for demographic, socioeconomic status, health care, chronic conditions, and health behavior variables. The overall age- and sex-adjusted prevalence of diabetes was 7.0%. Estimates were highest for Blacks (8.0%) followed by Arabs and Whites (7.0% for each group) and Chaldeans (6.0%). In the fully adjusted model, the association between ethnicity and diabetes was not statistically significant. Future studies should collect more detailed socioeconomic status, acculturation and health behavior information, which are factors that may affect the relationship between race/ethnicity and diabetes.

Continuous creation of matter across the black holes

International Nuclear Information System (INIS)

Manjunath, R

2006-01-01

The mass distribution in a galaxy that gets evolved around a black hole exhibits a certain degree of deterministic abstraction. The present work is based on the outcome of this abstraction. A black hole or a neutron star at the centre of a galaxy emits radiation when the edge of the galaxy gets disintegrated by getting absorbed in to another black hole or becomes a member of another galactic distribution. This is necessary for the existence of the black hole to counter for the surrounding structure with its own internal formation. The radiation is emitted as self similar pulses that exactly resemble the pattern of absorption of the rim of the galaxy. This concept is based on information geometry. An additional term that accounts for the feedback energy is appended to the energy momentum tensor. It has been shown that the mass around the black hole is distributed in bands that exhibit multiple resolutions. This translates on to self similarity in the emission pattern from the black hole. The recent emission of radiation from a neutron star is interpreted as one such phenomenon

Revitalizing quality assurance

International Nuclear Information System (INIS)

Hawkins, F.C.

1998-01-01

The image of someone inspecting or auditing often comes to mind when people hear the term quality assurance. Although partially correct, this image is not the complete picture. The person doing the inspecting or auditing is probably part of a traditional quality assurance organization, but that organization is only one aspect of a properly conceived and effectively implemented quality assurance system whose goal is improved facility safety and reliability. This paper introduces the underlying philosophies and basic concepts of the International Atomic Energy Agency's new quality assurance initiative that began in 1991 as part of a broad Agency-wide program to enhance nuclear safety. The first product of that initiative was publication in 1996 of a new Quality Assurance Code 50-C/SG-Q and fourteen related Safety Guides. This new suite of documents provide the technical and philosophical foundation upon which Member States can base their quality assurance programs. (author)

In today's interpretation 'quality assurance' means 'good management'. Quality assurance has to cover all phases of a work, but all quality assurance measures must be adapted to the relevance and complexity of the actual task. Examples are given for the preparation of quality classes, the organization of quality assurance during design and manufacturing and for auditing. Finally, efficiency and limits of quality assurance systems are described. (orig.)

Entropy and black-hole thermodynamics

International Nuclear Information System (INIS)

Wald, R.M.

1979-01-01

The concept of entropy is examined with an eye toward gaining insight into the nature of black-hole thermodynamics. Definitions of entropy are given for ordinary classical and quantum-mechanical systems which lead to plausibility arguments for the ordinary laws of thermodynamics. The treatment of entropy for a classical system is in the spirit of the information-theory viewpoint, but by explicitly incorporating the coarse-grained observable into the definition of entropy, we eliminate any nonobjective features. The definition of entropy for a quantum-mechanical system is new, but directly parallels the classical treatment. We then apply these ideas to a self-gravitating quantum system which contains a black hole. Under some assumptions: which, although nontrivial, are by no means exotic: about the nature of such a system, it is seen that the same plausibility arguments which lead to the ordinary laws of thermodynamics for ordinary systems now lead to the laws of black-hole mechanics, including the generalized second law of thermodynamics. Thus, it appears perfectly plausible that black-hole thermodynamics is nothing more than ordinary thermodynamics applied to a self-gravitating quantum system

Black US college women's strategies of sexual self-protection.

Anakaraonye, Amarachi R; Mann, Emily S; Annang Ingram, Lucy; Henderson, Andrea K

2018-04-24

While previous scholarship on the sexual practices of college students in the USA has explored how the co-constitution of whiteness, economic privilege and gender inequality are central to 'hooking up', less attention has been paid to how the sexual culture of predominantly white universities shape Black college women's sexual practices. In this article, we use an intersectional theoretical framework informed by Black feminism to analyse interviews with Black, cisgender, heterosexual women, aged 18-22, attending a university in the south-eastern USA. We explore how they interpret the university's sexual culture and in turn how that informs their sexual decision-making. We find that the intersection of racism and sexism limits Black college women's sexual partner options and leads them to pursue sexual relationships outside the university setting. While most do not engage in committed romantic relationships with off-campus partners, they do engage in a range of strategies to protect their social, emotional and sexual well-being. The study findings expand the scholarship on hook-up culture by centring the narratives of a group often excluded from the literature.

Floatable, Self-Cleaning, and Carbon-Black-Based Superhydrophobic Gauze for the Solar Evaporation Enhancement at the Air-Water Interface.

Science.gov (United States)

Liu, Yiming; Chen, Jingwei; Guo, Dawei; Cao, Moyuan; Jiang, Lei

2015-06-24

Efficient solar evaporation plays an indispensable role in nature as well as the industry process. However, the traditional evaporation process depends on the total temperature increase of bulk water. Recently, localized heating at the air-water interface has been demonstrated as a potential strategy for the improvement of solar evaporation. Here, we show that the carbon-black-based superhydrophobic gauze was able to float on the surface of water and selectively heat the surface water under irradiation, resulting in an enhanced evaporation rate. The fabrication process of the superhydrophobic black gauze was low-cost, scalable, and easy-to-prepare. Control experiments were conducted under different light intensities, and the results proved that the floating black gauze achieved an evaporation rate 2-3 times higher than that of the traditional process. A higher temperature of the surface water was observed in the floating gauze group, revealing a main reason for the evaporation enhancement. Furthermore, the self-cleaning ability of the superhydrophobic black gauze enabled a convenient recycling and reusing process toward practical application. The present material may open a new avenue for application of the superhydrophobic substrate and meet extensive requirements in the fields related to solar evaporation.

2014-01-01

This cross-sectional study of urban high schools in Johannesburg, South Africa, sought to examine eating attitudes, body image and self-esteem among male adolescents (n = 391). Anthropometric measurements, Eating Attitudes Test-26 (EAT-26), Rosenberg self-esteem, body image satisfaction and perception of females were collected at age 13, 15 and 17 years. Descriptive analysis was done to describe the sample, and non-parametric Wilcoxon Mann-Whitney test was used to test for significant differences between data that were not normally distributed (EAT-26). Spearman's rank correlation coefficient analyses were conducted to test for associations between self-esteem scores and eating attitudes, body mass indices and body image satisfaction scores. To assess the differences between groups that were normally distributed chi-square tests were carried out. Ethnic differences significantly affected adolescent boys' body mass index (BMI), eating attitudes and self-esteem; White boys had higher self-esteem, BMI and normal eating attitudes than the Black boys did. BMI was positively associated with self-esteem (p = 0.01, r = 0.134) and negatively with dieting behaviour in White boys (p = 0.004, r = -0.257), and with lower EAT-26 bulimic and oral control scores in Black boys. In conclusion, the findings highlight ethnic differences and a need to better understand cultural differences that influence adolescent attitudes and behaviour.

Pleasing the masses: messages for daily life management in African American women's popular media sources.

Science.gov (United States)

Black, Angela Rose; Peacock, Nadine

2011-01-01

Using African American women's insights on their own health experiences, we explored how their daily life management was linked to the "strong Black woman" (SBW) script, and the health implications of that script. Using the search term "strong Black woman," we identified 20 articles from African American women's magazines and 10 blog sites linked to the SBW script and analyzed their content. We created thematic categories (role management, coping, and self-care) and extracted issues relevant to African American women's health. Adherence to the SBW script was linked to women's daily life management and health experiences. Themes such as self-sacrificial role management ("please the masses"), emotional suppression ("game face"), and postponement of self-care ("last on the list") incited internal distress and evinced negative health consequences. Scientists, activists, and health care professionals would be aided in forming initiatives aimed at reducing health disparities among African American women by heeding the insights on their health experiences that they express in popular media sources.

Black Hole's 1/N Hair

CERN Document Server

Dvali, Gia

2013-01-01

According to the standard view classically black holes carry no hair, whereas quantum hair is at best exponentially weak. We show that suppression of hair is an artifact of the semi-classical treatment and that in the quantum picture hair appears as an inverse mass-square effect. Such hair is predicted in the microscopic quantum description in which a black hole represents a self-sustained leaky Bose-condensate of N soft gravitons. In this picture the Hawking radiation is the quantum depletion of the condensate. Within this picture we show that quantum black hole physics is fully compatible with continuous global symmetries and that global hair appears with the strength B/N, where B is the global charge swallowed by the black hole. For large charge this hair has dramatic effect on black hole dynamics. Our findings can have interesting astrophysical consequences, such as existence of black holes with large detectable baryonic and leptonic numbers.

An Older Transgender Woman's Quest for Identity.

Walker, Charles A; Cohen, Harriet; Jenkins, David

2016-02-01

Despite sensationalized media attention, transgender individuals are the most marginalized and misunderstood group in the lesbian, gay, bisexual, and transgender (LGBT) community. The current article presents a case study of one woman's quest for identity. Narrative inquiry was used to analyze data from interview transcripts and four themes emerged during analysis: (a) naming the ambiguity, (b) revealing-concealing the authentic self, (c) discovering the transgender community, and (d) embracing the "T" identity. Lifespan and empowerment theories were used to harvest meanings from these themes. Implications for nursing practice and research were examined based on study findings. Participatory action research offers an approach for future studies in which researchers advocate for transgender individuals and remove obstacles to their health care access.

Slowly balding black holes

International Nuclear Information System (INIS)

Lyutikov, Maxim; McKinney, Jonathan C.

2011-01-01

The 'no-hair' theorem, a key result in general relativity, states that an isolated black hole is defined by only three parameters: mass, angular momentum, and electric charge; this asymptotic state is reached on a light-crossing time scale. We find that the no-hair theorem is not formally applicable for black holes formed from the collapse of a rotating neutron star. Rotating neutron stars can self-produce particles via vacuum breakdown forming a highly conducting plasma magnetosphere such that magnetic field lines are effectively ''frozen in'' the star both before and during collapse. In the limit of no resistivity, this introduces a topological constraint which prohibits the magnetic field from sliding off the newly-formed event horizon. As a result, during collapse of a neutron star into a black hole, the latter conserves the number of magnetic flux tubes N B =eΦ ∞ /(πc(ℎ/2π)), where Φ ∞ ≅2π 2 B NS R NS 3 /(P NS c) is the initial magnetic flux through the hemispheres of the progenitor and out to infinity. We test this theoretical result via 3-dimensional general relativistic plasma simulations of rotating black holes that start with a neutron star dipole magnetic field with no currents initially present outside the event horizon. The black hole's magnetosphere subsequently relaxes to the split-monopole magnetic field geometry with self-generated currents outside the event horizon. The dissipation of the resulting equatorial current sheet leads to a slow loss of the anchored flux tubes, a process that balds the black hole on long resistive time scales rather than the short light-crossing time scales expected from the vacuum no-hair theorem.

Science.gov (United States)

2006-01-01

[figure removed for brevity, see original site] Poster Version This artist's concept shows a supermassive black hole at the center of a remote galaxy digesting the remnants of a star. NASA's Galaxy Evolution Explorer had a 'ringside' seat for this feeding frenzy, using its ultraviolet eyes to study the process from beginning to end. The artist's concept chronicles the star being ripped apart and swallowed by the cosmic beast over time. First, the intact sun-like star (left) ventures too close to the black hole, and its own self-gravity is overwhelmed by the black hole's gravity. The star then stretches apart (middle yellow blob) and eventually breaks into stellar crumbs, some of which swirl into the black hole (cloudy ring at right). This doomed material heats up and radiates light, including ultraviolet light, before disappearing forever into the black hole. The Galaxy Evolution Explorer was able to watch this process unfold by observing changes in ultraviolet light. The area around the black hole appears warped because the gravity of the black hole acts like a lens, twisting and distorting light.

Implication of Negative Temperature in the Inner Horizon of Reissner-Nordström Black Hole

Directory of Open Access Journals (Sweden)

Yuant Tiandho

2017-12-01

Full Text Available This paper reconsiders the properties of Hawking radiation in the inner horizon of a Reissner-Nordström black hole. Through the correlation between temperature and surface gravity, it is concluded that the temperature of the inner horizon is always negative and that of the outer horizon is always positive. Since negative temperature is hotter than any positive temperature, it is predicted that particle radiation from the inner horizon will move toward the outer horizon. However, unlike temperature, entropy in both horizons remains positive. Following the definition of negative temperature in the inner horizon, it is assured that the entropy of a black hole within a closed system can never decrease. By analyzing the conditions of an extremal black hole, the third law of black hole thermodynamics can be extended to multi-horizon black holes.

Non-linear Q-clouds around Kerr black holes

International Nuclear Information System (INIS)

Herdeiro, Carlos; Radu, Eugen; Rúnarsson, Helgi

2014-01-01

Q-balls are regular extended ‘objects’ that exist for some non-gravitating, self-interacting, scalar field theories with a global, continuous, internal symmetry, on Minkowski spacetime. Here, analogous objects are also shown to exist around rotating (Kerr) black holes, as non-linear bound states of a test scalar field. We dub such configurations Q-clouds. We focus on a complex massive scalar field with quartic plus hexic self-interactions. Without the self-interactions, linear clouds have been shown to exist, in synchronous rotation with the black hole horizon, along 1-dimensional subspaces – existence lines – of the Kerr 2-dimensional parameter space. They are zero modes of the superradiant instability. Non-linear Q-clouds, on the other hand, are also in synchronous rotation with the black hole horizon; but they exist on a 2-dimensional subspace, delimited by a minimal horizon angular velocity and by an appropriate existence line, wherein the non-linear terms become irrelevant and the Q-cloud reduces to a linear cloud. Thus, Q-clouds provide an example of scalar bound states around Kerr black holes which, generically, are not zero modes of the superradiant instability. We describe some physical properties of Q-clouds, whose backreaction leads to a new family of hairy black holes, continuously connected to the Kerr family

Self-image and ethnic identification in South Africa.

Bornman, E

1999-08-01

This study examined the relationship between self-image and ethnic identification among 3 South African groups. Participants included random samples of 347 Afrikaans-speaking Whites, 113 English-speaking Whites, and 466 Blacks in urban Gauteng. Positive and negative self-image were extracted using the Rosenberg Self-Esteem Scale (M. Rosenberg, 1965). Afrikaans-speaking Whites had the most positive self-image and Blacks the most negative self-image. A positive self-image was correlated with stronger ethnic identification among Afrikaans-speaking Whites. The opposite was true for Blacks. This relationship was insignificant among English-speaking Whites. Ambivalence toward ingroup identity was persistently correlated with self-image for all groups.

Financial assurances

International Nuclear Information System (INIS)

Paton, R.F.

1990-01-01

US Ecology is a full service waste management company. The company operates two of the nation's three existing low-level radioactive waste (LLRW) disposal facilities and has prepared and submitted license applications for two new LLRW disposal facilities in California and Nebraska. The issue of financial assurances is an important aspect of site development and operation. Proper financial assurances help to insure that uninterrupted operation, closure and monitoring of a facility will be maintained throughout the project's life. Unfortunately, this aspect of licensing is not like others where you can gauge acceptance by examining approved computer codes, site performance standards or applying specific technical formulas. There is not a standard financial assurance plan. Each site should develop its requirements based upon the conditions of the site, type of design, existing state or federal controls, and realistic assessments of future financial needs. Financial assurances at U.S. Ecology's existing sites in Richland, Washington, and Beatty, Nevada, have been in place for several years and are accomplished in a variety of ways by the use of corporate guarantees, corporate capital funds, third party liability insurance, and post closure/long-term care funds. In addressing financial assurances, one can divide the issue into three areas: Site development/operations, third party damages, and long-term care/cleanup

Merger transitions in brane-black-hole systems: Criticality, scaling, and self-similarity

International Nuclear Information System (INIS)

Frolov, Valeri P.

2006-01-01

We propose a toy model for studying merger transitions in a curved spacetime with an arbitrary number of dimensions. This model includes a bulk N-dimensional static spherically symmetric black hole and a test D-dimensional brane (D≤N-1) interacting with the black hole. The brane is asymptotically flat and allows a O(D-1) group of symmetry. Such a brane-black-hole (BBH) system has two different phases. The first one is formed by solutions describing a brane crossing the horizon of the bulk black hole. In this case the internal induced geometry of the brane describes a D-dimensional black hole. The other phase consists of solutions for branes which do not intersect the horizon, and the induced geometry does not have a horizon. We study a critical solution at the threshold of the brane-black-hole formation, and the solutions which are close to it. In particular, we demonstrate that there exists a striking similarity of the merger transition, during which the phase of the BBH system is changed, both with the Choptuik critical collapse and with the merger transitions in the higher dimensional caged black-hole-black-string system

This study examined associations between blood pressure (BP) and dispositional variables pertaining to anger and hostility. Black and White 25- to 44-year old male and female normotensives and unmedicated mild to moderate hypertensives completed four reliable self-report scales--the Cook-Medley Hostility (Ho) Scale, the Trait Anger subscale of the State-Trait Anger Scale (STAS-T), and the Cognitive Anger and Somatic Anger subscales of the Cognitive-Somatic Anger Scale--plus the Framingham Anger Scale and the Harburg Anger Scale. They also engaged in three laboratory tasks--Type A Structured Interview (SI), a video game, and a cold pressor task--that elicit cardiovascular reactivity. Ambulatory BP readings at home and at work were also obtained from most subjects. Blacks had significantly higher Ho and lower STAS-T scores than did Whites. Women reported higher levels of somatic anger than did men. White women showed significant positive correlations between STAS-T and systolic BP (SBP) and diastolic BP (DBP) both at rest in the laboratory and during the SI. Black women revealed significant positive relationships between STAS-T and SBP and DBP at rest in the laboratory and at work as well as with DBP during the cold pressor test. For Black men, cognitive anger and DBP at rest were positively related. In contrast, White men revealed significant negative correlations between Ho scores and SBP at rest and during the video game; these men also showed significant negative relationships between somatic anger and SBP and DBP reactivity during the cold pressor test. Women, but not men, showed significant positive relationships between all four anger measures and ambulatory BP at work. Whereas main effects relating anger and cardiovascular measures were not apparent as a function of race, Blacks demonstrated significantly greater SBP and DBP reactivity than Whites during the cold pressor test, with the converse occurring during the SI. Men demonstrated significantly greater

Enhancing the rate of tidal disruptions of stars by a self-gravitating disc around a massive central black hole

Directory of Open Access Journals (Sweden)

Šubr L.

2012-12-01

Full Text Available We further study the idea that a self-gravitating accretion disc around a supermassive black hole can increase the rate of gradual orbital decay of stellar trajectories (and hence tidal disruption events by setting some stars on eccentric trajectories. Cooperation between the gravitational field of the disc and the dissipative environment can provide a mechanism explaining the origin of stars that become bound tightly to the central black hole. We examine this process as a function of the black hole mass and conclude that it is most efficient for intermediate central masses of the order of ∼ 104Mʘ. Members of the cluster experience the stage of orbital decay via collisions with an accretion disc and by other dissipative processes, such as tidal effects, dynamical friction and the emission of gravitational waves. Our attention is concentrated on the region of gravitational dominance of the central body. Mutual interaction between stars and the surrounding environment establishes a non-spherical shape and anisotropy of the nuclear cluster. In some cases, the stellar sub-system acquires ring-type geometry. Stars of the nuclear cluster undergo a tidal disruption event as they plunge below the tidal radius of the supermassive black hole.

Destroying charged black holes in higher dimensions with test particles

Science.gov (United States)

Wu, Bin; Liu, Weiyang; Tang, Hao; Yue, Rui-Hong

2017-07-01

A possible way to destroy the Tangherlini Reissner-Nordström black hole is discussed in the spirit of Wald’s gedanken experiment. By neglecting radiation and self force effects, the absorbing condition and destruction condition of the test point particle which is capable of destroying the black hole are obtained. We find that it is impossible to challenge the weak cosmic censorship for an initially extremal black hole in all dimensions. Instead, it is shown that the near extremal black hole will turn into a naked singularity in this particular process, in which case the allowed range of the particle’s energy is very narrow. The result indicates that the self-force effects may well change the outcome of the calculation.

2015-03-01

Being 'with woman' is characterised as presence, a spiritual concept which is nevertheless bound up with physical space. In this article, the work of the American philosopher Judith Butler is used to explore the interplay between space and relationships in midwifery practice. Butler argues that relationships based on mutual recognition and respect define the actions possible within physical space. In midwifery, being with woman creates a therapeutic space necessary for the wellbeing and empowerment of women and midwives alike.

In a well managed project, Quality Assurance is an integral part of the management activities performed on a daily basis. Management assures successful performance within budget and on schedule by using all the good business, scientific, engineering, quality assurance, and safety practices available. Quality assurance and safety practices employed on Nova are put in perspective by integrating them into the overall function of good project management. The Nova assurance management system was developed using the quality assurance (QA) approach first implemented at LLNL in early 1978. The LLNL QA program is described as an introduction to the Nova assurance management system. The Nova system is described pictorially through the Nova configuration, subsystems and major components, interjecting the QA techniques which are being pragmatically used to assure the successful completion of the project

The elements (principles) of quality assurance can be applied to the operation of the analytical chemistry laboratory to provide an effective tool for indicating the competence of the laboratory and for helping to upgrade competence if necessary. When used, those elements establish the planned and systematic actions necessary to provide adequate confidence in each analytical result reported by the laboratory (the definition of laboratory quality assurance). The elements, as used at the Hanford Engineering Development Laboratory (HEDL), are discussed and they are qualification of analysts, written methods, sample receiving and storage, quality control, audit, and documentation. To establish a laboratory quality assurance program, a laboratory QA program plan is prepared to specify how the elements are to be implemented into laboratory operation. Benefits that can be obtained from using laboratory quality assurance are given. Experience at HEDL has shown that laboratory quality assurance is not a burden, but it is a useful and valuable tool for the analytical chemistry laboratory

A self-regulating braking mechanism in black-hole X-ray binaries

International Nuclear Information System (INIS)

Meyer, F.; Meyer-Hofmeister, E.

2001-01-01

The outbursts of black hole X-ray transients can be understood as caused by a limit cycle instability in the accretion disk, similar to dwarf nova outbursts. For adequately low mass overflow rates from the companion star long outburst recurrence times are expected. Buth the fact that we find predominantly long recurrence times or that only one X-ray nova outburst was detected at all poses a problem. The question arises whether any braking mechanism could act in a way that long recurrence times are favoured. We suggest that a circumbinary disk exists and brakes the orbital motion of the binary stars by tidal interaction. The irradiation during an outburst leads to mass loss by winds from the circumbinary disk, relieving the braking force until the removed matter is refilled by diffusion from outer parts. We show that this reduction of braking will self-adjust the mass transfer to the marginal rate that gives long recurrence times. (orig.)

Position of woman according to 19th century Montenegrin marital law

Directory of Open Access Journals (Sweden)

Kulauzov Maša

2013-01-01

Full Text Available Legal position of woman in 19th century Montenegrin marital law is examined in this paper. Provisions on entering into marriage, woman's marital infidelity, legal separation, dissolution of marriage and its legal effects as well as widow's property rights are scrutinized and critically analyzed. The author also indicates to rules of customary law regarding legal status of a married woman. Married woman had restricted legal capacity, as well as restricted property rights and no rights of succession. However, gender inequality common in patriarchal society such as Montenegrin in 19th century is particularly accentuated in case of marital infidelity. Only woman's adultery is punishable and regarded as a serious crime. Beside marital infidelity, lower position of woman is noticeable in all aspects of married life. Hence, legislative attempts to improve woman's legal status are emphasized in the article.

The pregnant woman and the good Samaritan: can a woman have a duty to undergo a caesarean section?

Science.gov (United States)

Scott, R

2000-01-01

Although a pregnant woman can now refuse any medical treatment needed by the fetus, the Court of Appeal has acknowledged that ethical dilemmas remain, adverting to the inappropriateness of legal compulsion of presumed moral duties in this context. This leaves the impression of an uncomfortable split between the ethics and the law. The notion of a pregnant woman refusing medical treatment needed by the fetus is troubling and it helps little simply to assert that she has a legal right to do so. At the same time, the idea that a pregnant woman fails in her moral duty unless she accepts any recommended treatment or surgery--however great the burden--is also not without difficulty. This article seeks to find a way between these two somewhat polarized positions by arguing that, instead of being a question primarily about whether legally to enforce moral obligations, the 'maternal-fetal conflict' begins with previously unrecognized difficulties in determining when a woman's prima facie moral rights invoked in the treatment context should 'give way' to the interests of the fetus. This difficulty is mirrored within the law. Thus, how can we tell when a pregnant woman has the moral or legal duty to submit to a caesarean section? Seen in this way, the conflict is a problem which lies at the interface between moral and legal rights and duties, showing that there are important conceptual links between the ethics and the law. Against this background, this article explores the limits of a pregnant woman's right to bodily integrity by focusing upon the idea of her moral duty to aid the fetus through her body. Here we find difficulties in determining the existence and extent of this somewhat extraordinary duty. Such a duty is contrasted with both negative and positive duties toward others in the course of 'general conduct.' Attention to the social context of pregnancy and the refusal of treatment within this is also instructive. Overall, the purpose is to foster understanding and

Biscan, R.; Fifnja, I.; Kavsek, D.

2012-01-01

International standards from nuclear power plant operation area are being frequently upgraded and revised in accordance with the continuous improvement philosophy. This philosophy applies also to the area of Quality Assurance, which has also undergone significant improvement since the early 1950s. Besides just nuclear industry, there are also other international quality standards that are being continuously developed and revised, bringing needs for upgrades also in the nuclear application. Since the beginning of Krsko NPP construction, the overall Quality Assurance program and its applicable procedures were in place to assure that all planned and systematic actions necessary to provide adequate confidence that an item or service will satisfy given requirements to quality, are in place. The overall requirements for quality as one of the major objectives for Krsko NPP operation are also set forth in the Updated Safety Analyses Report, the document that serves as a base for operating license. During more than 30 years of Krsko NPP operation, the quality requirements and related documents were revised and upgraded in several attempts. The latest revision 6 of QD-1, Quality Assurance Plan was issued during the year 2011. The bases for the revision were: Changes of the Slovenian regulatory requirements (ZVISJV, JV5, JV9?), Changes of Krsko NPP licensing documents (USAR section 13?), SNSA inspection requirements, Changes of international standards (IAEA, ISO?), Conclusions of first PSR, Implementation of ISO standards in Krsko NPP (ISO14001, ISO17025), Changes of plant procedures, etc. One of the most obvious changes was the enlargement of the QA Plan scope to cover interdisciplinary areas defined in the plant management program MD-1, such as Safety culture, Self-assessment, Human performance, Industrial Safety etc. The attachment of the QA Plan defining relationships between certain standards was also updated to provide matrix for better correlation of requirements of

General Self-Efficacy and Mortality in the USA; Racial Differences.

Assari, Shervin

2017-08-01

General self-efficacy has been historically assumed to have universal health implications. However, less is known about population differences in long-term health effects of general self-efficacy across diverse populations. This study compared black and white American adults for (1) the association between psychosocial and health factors and general self-efficacy at baseline, and (2) the association between baseline self-efficacy and long-term risk of all-cause mortality over 25 years. The Americans' Changing Lives (ACL) study, 1986-2011, is a nationally representative longitudinal cohort of US adults. The study followed 3361 black (n = 1156) and white (n = 2205) adults for up to 25 years. General self-efficacy as well as demographics, socioeconomics, stressful life events, health behaviors, obesity, depressive symptoms, and self-rated health were measured at baseline in 1986. The outcome was time to all-cause mortality since 1986. Race was the focal moderator. Logistic regression and proportional hazards models were used for data analysis. Although blacks had lower general self-efficacy, this association was fully explained by socioeconomic factors (education and income). Our logistic regression suggested interactions between race and education, self-rated health, and stress on general self-efficacy at baseline. Baseline general self-efficacy was associated with risk of mortality in the pooled sample. Race interacted with baseline general self-efficacy on mortality risk, suggesting stronger association for whites than blacks. Black-white differences exist in psychosocial and health factors associated with self-efficacy in the USA. Low general self-efficacy does not increase mortality risk for blacks. Future research should test whether socioeconomic status, race-related attitudes, world views, attributions, and locus of control can potentially explain why low self-efficacy is not associated with higher risk of mortality among American blacks.

Ecthyma gangrenosum in the periorbital region in a previously healthy immunocompetent woman without bacteremia

Somenath Sarkar

2016-01-01

Full Text Available Ecthyma gangrenosum (EG is a cutaneous lesion classically associated with potentially fatal Pseudomonas septicemia in immunocompromised patients. Other bacterial and fungal pathogens have also been implicated. Although EG typically occurs in immunocompromised or neutropenic patients, it may occasionally affect a previously healthy person. The cutaneous findings are characteristic with small indurated papulovesicles progressing rapidly to necrotic ulcers with surrounding erythema and a central black Eschar. While lesions can occur at any site, most are commonly found over the buttocks, perineum, limbs, and axillae. We describe a case of EG in periorbital region in a previously healthy woman who responded to appropriate antibiotic treatment for Pseudomonas. It is very important to establish the diagnosis early so that appropriate systemic antibiotic therapy can be initiated to reduce morbidity and potential mortality.

Science self-efficacy of African Americans enrolled in freshman level physical science courses in two historically black institutions

Prihoda, Belinda Ann

2011-12-01

Science education must be a priority for citizens to function and be productive in a global, technological society. African Americans receive fewer science degrees in proportion to the Caucasian population. The primary purposes of this study were to determine the difference between the pretest and posttest science self-efficacy scores of African-American nonscience majors, the difference between the pretest and posttest science self-efficacy scores of African-American science majors, the relationship between science self-efficacy and course grade, the relationship between gender and science self-efficacy score, and the relationship between science self-efficacy score and course withdrawal. This study utilized a Likert survey instrument. All participants were enrolled in freshman level courses in the physical sciences at a historically black institution: a college or university. Participants completed the pretest survey within two weeks after the 12th class day of the semester. Initially, 458 participants completed the pretest survey. The posttest was administered within two weeks before the final exam. Only 245 participants completed the posttest survey. Results indicate that there is a difference in science self-efficacy of science majors and nonscience majors. There was no significant difference between the pretest and posttest science self-efficacy scores of African-American science majors and nonscience majors. There was no significant relationship between science self-efficacy and course grade, gender and science self-efficacy score, and course withdrawal and science self-efficacy score.

This study was undertaken to compare ethnic and gender differences regarding self-esteem and various disordered eating attitudes and behaviors among elite college athletes. A total of 1445 student athletes from 11 Division I schools were surveyed using a 133-item questionnaire. White female athletes reported significantly lower self-esteem than Black female, Black male and White male athletes. Black female athletes' self-esteem was equal to both Black and White male athletes. White female athletes reported significantly higher drive for thinness, body dissatisfaction, and more disturbed eating behaviors than Black female and both groups of male athletes. The current study demonstrates that White female athletes appear to be most at risk for having difficulty with eating disorders. Their reporting of significantly lower self-esteem indicates that this may be a risk factor that is more characteristic of this ethnic group. Questions are raised about what factors exist in the Black female culture that protect them from low self-esteem and disordered eating attitudes and behaviors.

Quality assurance handbook for measurement laboratories

International Nuclear Information System (INIS)

Delvin, W.L.

1984-10-01

This handbook provides guidance in the application of quality assurance to measurement activities. It is intended to help those persons making measurements in applying quality assurance to their work activities by showing how laboratory practices and quality assurance requirements are integrated to provide control within those activities. The use of the guidance found in this handbook should help provide consistency in the interpretation of quality assurance requirements across all types of measurement laboratories. This handbook also can assist quality assurance personnel in understanding the relationships between laboratory practices and quality assurance requirements. The handbook is composed of three chapters and several appendices. Basic guidance is provided by the three chapters. In Chapter 1, the role of quality assurance in obtaining quality data and the importance of such data are discussed. Chapter 2 presents the elements of laboratory quality assurance in terms of practices that can be used in controlling work activities to assure the acquisition of quality data. Chapter 3 discusses the implementation of laboratory quality assurance. The appendices provide supplemental information to give the users a better understanding of the following: what is quality assurance; why quality assurance is required; where quality assurance requirements come from; how those requirements are interpreted for application to laboratory operations; how the elements of laboratory quality assurance relate to various laboratory activities; and how a quality assurance program can be developed

Metabolomics promises a holistic phenotypic characterization of biological responses to toxicants. This technology is based on advanced chemical analytical tools with reasonable throughput, including mass-spectroscopy and NMR. Quality assurance, however - from experimental design, sample preparation, metabolite identification, to bioinformatics data-mining - is urgently needed to assure both quality of metabolomics data and reproducibility of biological models. In contrast to microarray-based transcriptomics, where consensus on quality assurance and reporting standards has been fostered over the last two decades, quality assurance of metabolomics is only now emerging. Regulatory use in safety sciences, and even proper scientific use of these technologies, demand quality assurance. In an effort to promote this discussion, an expert workshop discussed the quality assurance needs of metabolomics. The goals for this workshop were 1) to consider the challenges associated with metabolomics as an emerging science, with an emphasis on its application in toxicology and 2) to identify the key issues to be addressed in order to establish and implement quality assurance procedures in metabolomics-based toxicology. Consensus has still to be achieved regarding best practices to make sure sound, useful, and relevant information is derived from these new tools.

Stationary Black Holes: Uniqueness and Beyond

Full Text Available The spectrum of known black hole solutions to the stationary Einstein equations has increased in an unexpected way during the last decade. In particular, it has turned out that not all black hole equilibrium configurations are characterized by their mass, angular momentum and global charges. Moreover, the high degree of symmetry displayed by vacuum and electro-vacuum black hole space-times ceases to exist in self-gravitating non-linear field theories. This text aims to review some of the recent developments and to discuss them in the light of the uniqueness theorem for the Einstein-Maxwell system.

Pregnant woman mode for absorbed fraction calculations

International Nuclear Information System (INIS)

Cloutier, R.J.; Snyder, W.S.; Watson, E.E.

1977-01-01

The most radiation-sensitive segment of our population is the developing fetus. Until recently, methods available for calculating the dose to the fetus were inadequate because a model for the pregnant woman was not available. Instead, the Snyder and Fisher model of Reference Man, which includes a uterus, was frequently used to calculate absorbed fractions when the source was in various organs of the body and the nongravid uterus was the target. These values would be representative of the dose to the embryo during the early stages of pregnancy. Unfortunately, Reference Man is considerable larger than Reference Woman. The authors recently reported on the design of a Reference Woman phantom that has dimensions quite similar to the ICRP Reference Woman. This phantom was suitable for calculating the dose to the embryo during early stages of pregnancy (0 to 3 mo.), but was not suitable for the later stages of pregnancy because of the changing shape of the mother and the displacement of several abdominal organs brought about by the growth of the uterus and fetus. The models of Reference Woman that were subsequently developed for each month of pregnancy are described. The models take into account the growth of the uterus and fetus and the repositioning of the various abdominal organs. These models have been used to calculate absorbed fractions for the fetus as a target and the gastrointestinal tract as a source of radiation for twelve photon energies ranging from 10 keV to 4 MeV

Relationship of sex, achievement, and science self-concept to the science career preferences of black students

Science.gov (United States)

Jacobowitz, Tina

Science career preferences of junior high school-aged students, while not stable predictors of ultimate career choice, do serve to direct and maintain individuals along the paths to careers in science. In this study, factors relevant to science career preferences of black eighth grade students were investigated. This issue is of particular import to blacks since they are severely underrepresented in the scientific fields. The sample consisted of 113 males and 148 females in an inner city junior high school. The Science Career Preference Scale, the Peabody Picture Vocabulary Test, and the Self-Concept of Ability Scale (Form B-Science) were administered. Mathematics and science grades were obtained from class rating sheets. Treatment of the data involved multiple regression analysis according to a hierarchical model. Results showed that of all the independent variables, sex was the strongest predictor of science career preferences, accounting for 25% of the criterion variance. The findings suggest that early adolescent science career preferences are related more to interests that are consonant with sex-role considerations than realistic assessment of mathematics or science achievement.

The generalized second law and the black hole evaporation in an empty space as a nonequilibrium process

International Nuclear Information System (INIS)

Saida, Hiromi

2006-01-01

When a black hole is in an empty space in which there is no matter field except that of the Hawking radiation (Hawking field), then the black hole evaporates and the entropy of the black hole decreases. The generalized second law guarantees the increase of the total entropy of the whole system which consists of the black hole and the Hawking field. That is, the increase of the entropy of the Hawking field is faster than the decrease of the black hole entropy. In a naive sense, one may expect that the entropy increase of the Hawking field is due to the self-interaction among the composite particles of the Hawking field, and that the self-relaxation of the Hawking field results in the entropy increase. Then, when one considers a non-self-interacting matter field as the Hawking field, it is obvious that self-relaxation does not take place, and one may think that the total entropy does not increase. However, using nonequilibrium thermodynamics which has been developed recently, we find for the non-self-interacting Hawking field that the rate of entropy increase of the Hawking field (the entropy emission rate by the black hole) grows faster than the rate of entropy decrease of the black hole during the black hole evaporation in empty space. The origin of the entropy increase of the Hawking field is the increase of the black hole temperature. Hence an understanding of the generalized second law in the context of nonequilibrium thermodynamics is suggested; even if the self-relaxation of the Hawking field does not take place, the temperature increase of the black hole during the evaporation process causes the entropy increase of the Hawking field to result in the increase of the total entropy

'I am not the kind of woman who complains of everything': illness stories on self and shame in women with chronic pain.

Science.gov (United States)

Werner, Anne; Isaksen, Lise Widding; Malterud, Kirsti

2004-09-01

In this study, we explore issues of self and shame in illness accounts from women with chronic pain. We focused on how these issues within their stories were shaped according to cultural discourses of gender and disease. A qualitative study was conducted with in-depth interviews including a purposeful sampling of 10 women of varying ages and backgrounds with chronic muscular pain. The women described themselves in various ways as 'strong', and expressed their disgust regarding talk of illness of other women with similar pain. The material was interpreted within a feminist frame of reference, inspired by narrative theory and discourse analysis. We read the women's descriptions of their own (positive) strength and the (negative) illness talk of others as a moral plot and argumentation, appealing to a public audience of health personnel, the general public, and the interviewer: As a plot, their stories attempt to cope with psychological and alternative explanations of the causes of their pain. As performance, their stories attempt to cope with the scepticism and distrust they report having been met with. Finally, as arguments, their stories attempt to convince us about the credibility of their pain as real and somatic rather than imagined or psychological. In several ways, the women negotiated a picture of themselves that fits with normative, biomedical expectations of what illness is and how it should be performed or lived out in 'storied form' according to a gendered work of credibility as woman and as ill. Thus, their descriptions appear not merely in terms of individual behaviour, but also as organized by medical discourses of gender and diseases. Behind their stories, we hear whispered accounts relating to the medical narrative about hysteria; rejections of the stereotype medical discourse of the crazy, lazy, illness-fixed or weak woman.

Woman in Roman law: Subject or object of the law?

Directory of Open Access Journals (Sweden)

Bogunović Mirjana

2012-01-01

Full Text Available In Rome, legal status of woman and her factual possibilities of impact on public life were in serious discrepancy. General attitude of the legal status of woman in time of Romans is best shown by Papinian, 'In many provisions of our law, the position of woman is worse than of man (D.9.1.5.'. Every free Roman woman was considered a subject of law, according to classical Roman law. Nevertheless, there were extensive legislations that limited her legal and business capacity. Naturally, woman did not have legal personality in all periods of Roman state and her legal status was adjusted to the factual changes that had occurred in Roman society. What makes her position specific in Rome is progressive social role that did not exist in Greek-Asian world. From these previously mentioned views, which were confronting, it is possible to draw some doubts. Was woman really on the margins of political happenings, or was she an actual actor, even initiator, of some political events?.

The acute tobacco withdrawal syndrome among black smokers.

2014-03-01

Black smokers have greater difficulty quitting tobacco than White smokers, but the mechanisms underlying between-race differences in smoking cessation are not clear. One possibility is that Black smokers experience greater acute withdrawal than Whites. We investigated whether Black (n = 104) and White smokers (n = 99) differed in abstinence-induced changes in self-report, physiological, and cognitive performance measures. Smokers not wishing to quit completed two counterbalanced experimental sessions. Before one session, they abstained from smoking for at least 12 hr. They smoked normally before the other session. Black smokers reported smaller abstinence-induced changes on a number of subjective measures including the total score of the 10-item Questionnaire for Smoking Urges (QSU) and the total score of the Wisconsin Smoking Withdrawal Scale (WSWS). However, on most subjective measures, and on all objective measures, there were no between-race differences in abstinence-induced change scores. Moreover, Black participants did not report lower QSU and WSWS ratings at the abstinent session, but they did experience significantly higher QSU and WSWS ratings at the nonabstinent session. Abstinence-induced changes in subjective, physiological, and cognitive measures in White smokers were similar for smokers of nonflavored and menthol-flavored cigarettes. There was no evidence that Black smokers experienced greater acute tobacco withdrawal than Whites. To the contrary, Black participants experienced smaller abstinence-induced changes in self-reported craving and withdrawal on some measures. Racial differences in smoking cessation are unlikely to be explained by acute withdrawal.

An asymptotically consistent approximant for the equatorial bending angle of light due to Kerr black holes

Barlow, Nathaniel S.; Weinstein, Steven J.; Faber, Joshua A.

2017-07-01

An accurate closed-form expression is provided to predict the bending angle of light as a function of impact parameter for equatorial orbits around Kerr black holes of arbitrary spin. This expression is constructed by assuring that the weak- and strong-deflection limits are explicitly satisfied while maintaining accuracy at intermediate values of impact parameter via the method of asymptotic approximants (Barlow et al 2017 Q. J. Mech. Appl. Math. 70 21-48). To this end, the strong deflection limit for a prograde orbit around an extremal black hole is examined, and the full non-vanishing asymptotic behavior is determined. The derived approximant may be an attractive alternative to computationally expensive elliptical integrals used in black hole simulations.

Timely diagnosis of human immunodeficiency virus (HIV) enables access to antiretroviral treatment, which reduces mortality, morbidity and further transmission in people living with HIV. In the UK, late diagnosis among black African people persists. Novel methods to enhance HIV testing in this population are needed. To develop a self-sampling kit (SSK) intervention to increase HIV testing among black Africans, using existing community and health-care settings (stage 1) and to assess the feasibility for a Phase III evaluation (stage 2). A two-stage, mixed-methods design. Stage 1 involved a systematic literature review, focus groups and interviews with key stakeholders and black Africans. Data obtained provided the theoretical base for intervention development and operationalisation. Stage 2 was a prospective, non-randomised study of a provider-initiated, HIV SSK distribution intervention targeted at black Africans. The intervention was assessed for cost-effectiveness. A process evaluation explored feasibility, acceptability and fidelity. Twelve general practices and three community settings in London. HIV SSK return rate. Stage 1 - the systematic review revealed support for HIV SSKs, but with scant evidence on their use and clinical effectiveness among black Africans. Although the qualitative findings supported SSK distribution in settings already used by black Africans, concerns were raised about the complexity of the SSK and the acceptability of targeting. These findings were used to develop a theoretically informed intervention. Stage 2 - of the 349 eligible people approached, 125 (35.8%) agreed to participate. Data from 119 were included in the analysis; 54.5% (65/119) of those who took a kit returned a sample; 83.1% of tests returned were HIV negative; and 16.9% were not processed, because of insufficient samples. Process evaluation showed the time pressures of the research process to be a significant barrier to feasibility. Other major barriers were

Can a primordial black hole or wormhole grow as fast as the universe?

Carr, B J; Harada, Tomohiro; Maeda, Hideki

2010-01-01

This review addresses the issue of whether there are physically realistic self-similar solutions in which a primordial black hole is attached to an exact or asymptotically Friedmann model for an equation of state of the form p = (γ - 1)ρc 2 . In the positive-pressure case (1 < γ < 2), there is no solution in which the black hole is attached to an exact Friedmann background via a sonic point. However, there is a one-parameter family of black hole solutions which are everywhere supersonic and asymptotically quasi-Friedmann, in the sense that they contain a solid angle deficit at large distances. Such solutions exist providing the ratio of the black hole size to the cosmological horizon size is above some critical value and they include 'universal' black holes with an apparent horizon but no event horizon. In the stiff case (γ = 2), there is no self-similar solution in an exact background unless the matter turns into null dust before entering the event horizon; otherwise the only black hole solutions are probably asymptotically quasi-Friedmann universal ones. For a dark-energy-dominated universe (0 < γ < 2/3), there is a one-parameter family of black hole solutions which are properly asymptotically Friedmann (i.e. with no angle deficit) and the ratio of the black hole size to the cosmological horizon size is below some critical value. Above this value, one finds a self-similar cosmological wormhole solution which connects two asymptotic regions: one exactly Friedmann and the other asymptotically quasi-Friedmann. We also consider the possibility of self-similar black hole solutions in a universe dominated by a scalar field. This is like the stiff fluid case if the field is massless, but the situation is less clear if the scalar field is rolling down a potential and therefore massive, as in the quintessence scenario. Although no explicit asymptotically Friedmann black hole solutions of this kind are known, they may exist if the black hole is not too large. (brief

GALAXY FORMATION WITH SELF-CONSISTENTLY MODELED STARS AND MASSIVE BLACK HOLES. I. FEEDBACK-REGULATED STAR FORMATION AND BLACK HOLE GROWTH

International Nuclear Information System (INIS)

Kim, Ji-hoon; Abel, Tom; Wise, John H.; Alvarez, Marcelo A.

2011-01-01

There is mounting evidence for the coevolution of galaxies and their embedded massive black holes (MBHs) in a hierarchical structure formation paradigm. To tackle the nonlinear processes of galaxy-MBH interaction, we describe a self-consistent numerical framework which incorporates both galaxies and MBHs. The high-resolution adaptive mesh refinement (AMR) code Enzo is modified to model the formation and feedback of molecular clouds at their characteristic scale of 15.2 pc and the accretion of gas onto an MBH. Two major channels of MBH feedback, radiative feedback (X-ray photons followed through full three-dimensional adaptive ray tracing) and mechanical feedback (bipolar jets resolved in high-resolution AMR), are employed. We investigate the coevolution of a 9.2 x 10 11 M sun galactic halo and its 10 5 M sun embedded MBH at redshift 3 in a cosmological ΛCDM simulation. The MBH feedback heats the surrounding interstellar medium (ISM) up to 10 6 K through photoionization and Compton heating and locally suppresses star formation in the galactic inner core. The feedback considerably changes the stellar distribution there. This new channel of feedback from a slowly growing MBH is particularly interesting because it is only locally dominant and does not require the heating of gas globally on the disk. The MBH also self-regulates its growth by keeping the surrounding ISM hot for an extended period of time.

The impact of self esteem and Locus of Control (LoC) on clinical presentation across different ethnic groups of patients at their first psychotic episode (FEP) remains unknown. We explored these constructs in 257 FEP patients (Black n=95; White British n=119) and 341 controls (Black n=70; White British n=226), and examined their relationship with symptom dimensions and pathways to care. FEP patients presented lower self-esteem and a more external LoC than controls. Lower self esteem was associated with a specific symptoms profile (more manic and less negative symptoms), and with factors predictive of poorer outcome (longer duration of untreated psychosis (DUP) and compulsory mode of admission). A more external LoC was associated with more negative symptoms and an insidious onset. When we explored these constructs across different ethnic groups, we found that Black patients had significantly higher self esteem than White British. This was again associated with specific symptom profiles. While British patients with lower self esteem were more likely to report delusions, hallucinations and negative symptoms, Black patients with a lower self esteem showed less disorganization symptoms. These findings suggest that self esteem and LoC may represent one way in which social experiences and contexts differentially influence vulnerable individuals along the pathway to psychosis.

A 69-year-old black woman with an insulinoma presented with recurrent episodes of sweating and confusion culminating in two episodes of hypoglycaemic coma. The diagnosis was confirmed by finding an inappropriately elevated serum insulin level in the presence of hypoglycaemia after a fast of 14 hours. Computed tomography revealed a large tumour in the head of the pancreas. Removal of the tumour necessitated partial resection of the head and body of the pancreas, which in turn necessitated certain repair and drainage procedures. Postoperative complications, while not insignificant, were acceptable. At 1-year follow-up the patient is well. 4 figs., 4 refs

We illustrate how Hawking's radiance from a Schwarzschild black hole is modified by the electrostatic self-interaction of the emitted charged particles. A W.K.B approximation shows that the probability for a self-interacting charged particle to propagate from the interior to the exterior of the horizon is increased relative to the corresponding probability for neutral particles. We also demonstrate how the electric potential of a charged test object in the black hole's vicinity gives rise to ...

A grave of a Cuman noble woman in the Kislyakovsky 13 kurgan cemetery (Krasnodar kray

Directory of Open Access Journals (Sweden)

Boris Raev

2017-12-01

Full Text Available The Kislyakovskiy 13 kurgan cemetery was excavated in 2008 by an expedition of the Southern Scientific Center, RAS. Kurgan 2 contained two graves – one dated to the first centuries AD, the other to the Middle Ages, when the North Black Sea steppes were inhabited by the nomadic Polovеts tribes. This article discusses grave 2. The burial was made in a chamber in the form of a niche. Robbers destroyed one of the grave’s walls but the burial remained undisturbed. The buried woman of 35-40 years old was laying extended on back, head to west. Decayed wood from the funerary stretchers preserved under the skeleton. The rich grave goods included a bronze cauldron, an iron knife, two silver torques, hair rings, and a mirror. Fragments of the wooden frame, felt, textile, and gilded silver foil from a headdress preserved in area of the woman’s chest. The kurgan was encircled by a ditch; its northern part had two ledged niches made in the outer wall. Animal bones and ceramic shards with remains of the funerary feast were unearthed on the ditch bottom. The ditch was thoroughly made and has unique construction features. Judging by its lower layers, the dug-out soil was stacked not only on the kurgan’s surface but also round the ditch’s outer perimeter. The ditch remained opened for a long time and was gradually filled with flooded soil. Grave goods are typical for the Cuman graves of the 12th - early 13th centuries. The assemblage suggests a high social status of the buried woman. It is possible that for some time the area surrounded by the ditch was used as a sanctuary; afterwards the burial of a noble woman was performed, the kurgan was covered with a layer of soil.

Cosmology with primordial black holes

International Nuclear Information System (INIS)

Lindley, D.

1981-09-01

Cosmologies containing a substantial amount of matter in the form of evaporating primordial black holes are investigated. A review of constraints on the numbers of such black holes, including an analysis of a new limit found by looking at the destruction of deuterium by high energy photons, shows that there must be a negligible population of small black holes from the era of cosmological nucleosynthesis onwards, but that there are no strong constraints before this time. The major part of the work is based on the construction of detailed, self-consistent cosmological models in which black holes are continually forming and evaporating The interest in these models centres on the question of baryon generation, which occurs via the asymmetric decay of a new type of particle which appears as a consequence of the recently developed Grand Unified Theories of elementary particles. Unfortunately, there is so much uncertainty in the models that firm conclusions are difficult to reach; however, it seems feasible in principle that primordial black holes could be responsible for a significant part of the present matter density of the Universe.

Full Text Available Discourses on woman/space relations boomed in the 90s. The fundamental reason was to give support to the Feminist Movement. This trend which has had feeble effect on architectural design remained controversial. The comprehensive research expounded in this article which was based on an open-ended questionnaire that targeted at determining the gender roles at home, applied to female subjects who simulated the national demographics, clearly demonstrated that the home experience of an average Turkish woman basically consists of kitchens; the female who runs the house does not really have a place for herself at home. However she does not perceive her restrained, secondary role an issue worthy of struggling to change and she grants spaces for recreation and study to the male. The well-established civil laws conducive for equality has not changed this disturbing situation and do not seem to do so in the near future.

2012-01-01

We summarize our recent results on the evolution of super-massive black holes in the cores of galaxies. Our models are based on the viscous, Eddington-limited evolution of self-gravitating accretion disks. We find that, within this framework, one can explain the growth time scales and the luminosities of individual objects as well as the variation of these quantities for AGN with different black hole masses.

1993-12-31

K & S operates the largest and one of the most comprehensive Accredited Dosimetry Calibration Laboratories (ADCLs) in the American Association of Physicists in Medicine (AAPM) secondary laboratory system. It offers calibrations covering energies from Grenz-Ray (0.03-mm Al) to cesium-137 and cobalt-60, brachytherapy source and well chamber calibrations for low-activity sources, and, recently, high-dose-rate iridium-192. The present Quality Assurance (QA) program at K & S began with the AAPM Guidelines for Accreditation (Task Group No. 22 and No. 3, 1989) and grew over the past 10 years to include all aspects of providing a private, self-supporting calibration service from a free-standing independent facility. Some aspects of the QA program were prompted by the requirements of the nuclear power industry while other parts were from national consensus standards or the experiences of staff. Redundancy and teamwork are the most important characteristics of this QA program. K & S has participated in a National Institute of Standards and Technology (NIST) measurement quality assurance (MQA) program since 1982, and, in recent years, an ADCL intralaboratory intercomparison was conducted by Task Group 3 of the Radiation Therapy Committee of the AAPM. One measure of the credibility of a QA program is consistent performance on the MQA program and the ADCL intercomparisons over the past 10 years. An equally important measure of the ability of a program to assure quality results is the frequency of reported errors.

The numerical dosimetry of pregnant women is an important issue in electromagnetic-field safety. However, an anatomically realistic whole-body pregnant-woman model for electromagnetic dosimetry has not been developed. Therefore, we have developed a high-resolution whole-body model of pregnant women. A new fetus model including inherent tissues of pregnant women was constructed on the basis of abdominal magnetic resonance imaging data of a 26-week-pregnant woman. The whole-body pregnant-woman model was developed by combining the fetus model and a nonpregnant-woman model that was developed previously. The developed model consists of about 7 million cubical voxels of 2 mm size and is segmented into 56 tissues and organs. This pregnant-woman model is the first completely anatomically realistic voxel model that includes a realistic fetus model and enables a numerical simulation of electromagnetic dosimetry up to the gigahertz band. In this paper, we also present the basic specific absorption rate characteristics of the pregnant-woman model exposed to vertically and horizontally polarized electromagnetic waves from 10 MHz to 2 GHz

Huck, R.

1990-01-01

The presentation topic is California's approach to license application review in meeting financial assurances for the proposed Ward Valley site. The purpose of the presentation is to provide information on specific financial assurance provisions contained in 10 CFR Part 61 and how California intends to satisfy those requirements. Also, as rate setter, California intends to demonstrate how it will assure allowable costs to the rate base though a financial prudency review. The key provisions of financial assurance are: 10 CFR Section 61.61 - This provision requires an applicant to demonstrate its ability to finance licensed activities; 10 CFR Section 61.62 - This provision requires an applicant to provide assurance that sufficient funds will be available for site closure and stabilization; and 10 CFR Section 61.63 - This provision requires an applicant to provide 'a copy of a binding arrangement, such as a lease, between the applicant and the disposal site owner, so that sufficient funds will be available to cover the costs of the institutional control period.' To assist California in its determination of financial assurance compliance to be demonstrated by the applicant for Part 61 requirements, is NUREG guidance document 1199 'Standard Format and Content of a License Application for a Low-Level Radioactive Waste (LLRW) Disposal Facility.' The detailed financial assurance provisions of NUREG 1199 are then embodied in NUREG 1200, 'Standard Review Plant for the Review of a License Application for a LLRW Disposal Facility.'

1980-11-01

In the nuclear industry design specifications for certain quality characteristics require that the final product be inspected by a sampling plan which can demonstrate product conformance to stated assurance levels. The Specified Assurance Level (SAL) Sampling Procedure has been developed to permit the direct selection of attribute sampling plans which can meet commonly used assurance levels. The SAL procedure contains sampling plans which yield the minimum sample size at stated assurance levels. The SAL procedure also provides sampling plans with acceptance numbers ranging from 0 to 10, thus, making available to the user a wide choice of plans all designed to comply with a stated assurance level

An asymptotically consistent approximant for the equatorial bending angle of light due to Kerr black holes

Barlow, Nathaniel S; Faber, Joshua A; Weinstein, Steven J

2017-01-01

An accurate closed-form expression is provided to predict the bending angle of light as a function of impact parameter for equatorial orbits around Kerr black holes of arbitrary spin. This expression is constructed by assuring that the weak- and strong-deflection limits are explicitly satisfied while maintaining accuracy at intermediate values of impact parameter via the method of asymptotic approximants (Barlow et al 2017 Q. J. Mech. Appl. Math . 70 21–48). To this end, the strong deflection limit for a prograde orbit around an extremal black hole is examined, and the full non-vanishing asymptotic behavior is determined. The derived approximant may be an attractive alternative to computationally expensive elliptical integrals used in black hole simulations. (paper)

Ancient and modern women in the "Woman's World".

Science.gov (United States)

Hurst, Isobel

2009-01-01

Under the editorship of Oscar Wilde, the "Woman's World" exemplified the popular dissemination of Hellenism through periodical culture. Addressing topics such as marriage, politics, and education in relation to the lives of women in the ancient world, the magazine offered an unfamiliar version of the reception of ancient Greece and Rome in late-Victorian aestheticism, one that was accessible to a wide readership because it was often based on images rather than texts. The classical scholar Jane Ellen Harrison addressed herself to this audience of women readers, discussing the similarities between modern collegiate life and the "woman's world" that enabled Sappho to flourish in ancient Greece. The "Woman's World" thus questions gender stereotypes by juxtaposing ancient and modern women, implicitly endorsing varied models of womanhood.

Logarithmic entropy of Kehagias-Sfetsos black hole with self-gravitation in asymptotically flat IR modified Horava gravity

International Nuclear Information System (INIS)

Liu Molin; Lu Junwang

2011-01-01

Motivated by recent logarithmic entropy of Horava-Lifshitz gravity, we investigate Hawking radiation for Kehagias-Sfetsos black hole from tunneling perspective. After considering the effect of self-gravitation, we calculate the emission rate and entropy of quantum tunneling by using Kraus-Parikh-Wilczek method. Meanwhile, both massless and massive particles are considered in this Letter. Interestingly, two types tunneling particles have the same emission rate Γ and entropy S b whose analytical formulae are Γ=exp[π(r in 2 -r out 2 )/2+π/αlnr in /r out ] and S b =A/4+π/αln(A/4), respectively. Here, α is the Horava-Lifshitz field parameter. The results show that the logarithmic entropy of Horava-Lifshitz gravity could be explained well by the self-gravitation, which is totally different from other methods. The study of this semiclassical tunneling process may shed light on understanding the Horava-Lifshitz gravity.

The study investigated the relationship between body mass index and self-concept among adolescent black female university students. The study used a mixed research design (quantitative and qualitative methods). Media images of handsome faces and beautiful bodies are used to sell almost everything, from clothes and cosmetic to luncheon, meats, and so on. These images reinforce the western cultural stereotype that women should be thin and shapely to be attractive. Thus, as some girls go through puberty they may become dissatisfied with their weight, and to a lesser extent, with their shape, thus, developing low self-concept or imae of themselves. It is in this context that the study was conceptualised. First year female students from three different Schools and Faculties at the University of Limpopo, Turfloop Campus, South Africa, participated in the study. Using the availability and convenient sampling method, 75 students were selected for this study. For the quantitative aspect of the study, the Rosenberg Self-esteem Measure was used to measure self-esteem. For the qualitative part, a topic guide was used for the focus group discussions. Analysis of Variance (ANOVA) and the Pearson's Product Moment Correlation were used to analyse the quantitative data, while the phenomenological principle of open coding used for the thematic analysis. Results showed that there is a relationship between body mass and self-concept and that overweight participants tend to have a low self-esteem. Low self-esteem was perceived to be aggravated by a number of factors, like the attitude of the media and the society. Participants who are overweight also indicated that they are limited in certain activities of daily living (e.g., sports) as a result of their body mass. They expressed mixed feelings and frustration when it comes to such activities. The above results did not differ from those reported from western cultures.

There is mounting evidence for the coevolution of galaxies and their embedded massive black holes (MBHs) in a hierarchical structure formation paradigm. To tackle the nonlinear processes of galaxy-MBH interaction, we describe a self-consistent numerical framework which incorporates both galaxies and MBHs. The high-resolution adaptive mesh refinement (AMR) code Enzo is modified to model the formation and feedback of molecular clouds at their characteristic scale of 15.2 pc and the accretion of gas onto an MBH. Two major channels of MBH feedback, radiative feedback (X-ray photons followed through full three-dimensional adaptive ray tracing) and mechanical feedback (bipolar jets resolved in high-resolution AMR), are employed. We investigate the coevolution of a 9.2 x 10{sup 11} M {circle_dot} galactic halo and its 10{sup 5} {circle_dot} M embedded MBH at redshift 3 in a cosmological CDM simulation. The MBH feedback heats the surrounding interstellar medium (ISM) up to 10{sup 6} K through photoionization and Compton heating and locally suppresses star formation in the galactic inner core. The feedback considerably changes the stellar distribution there. This new channel of feedback from a slowly growing MBH is particularly interesting because it is only locally dominant and does not require the heating of gas globally on the disk. The MBH also self-regulates its growth by keeping the surrounding ISM hot for an extended period of time.

Interior structure of rotating black holes. III. Charged black holes

International Nuclear Information System (INIS)

Hamilton, Andrew J. S.

2011-01-01

This paper extends to the case of charged rotating black holes the conformally stationary, axisymmetric, conformally separable solutions presented for uncharged rotating black holes in a companion paper. In the present paper, the collisionless fluid accreted by the black hole may be charged. The charge of the black hole is determined self-consistently by the charge accretion rate. As in the uncharged case, hyper-relativistic counterstreaming between ingoing and outgoing streams drives inflation at (just above) the inner horizon, followed by collapse. If both ingoing and outgoing streams are charged, then conformal separability holds during early inflation, but fails as inflation develops. If conformal separability is imposed throughout inflation and collapse, then only one of the ingoing and outgoing streams can be charged: the other must be neutral. Conformal separability prescribes a hierarchy of boundary conditions on the ingoing and outgoing streams incident on the inner horizon. The dominant radial boundary conditions require that the incident ingoing and outgoing number densities be uniform with latitude, but the charge per particle must vary with latitude such that the incident charge densities vary in proportion to the radial electric field. The subdominant angular boundary conditions require specific forms of the incident number- and charge-weighted angular motions. If the streams fall freely from outside the horizon, then the prescribed angular conditions can be achieved by the charged stream, but not by the neutral stream. Thus, as in the case of an uncharged black hole, the neutral stream must be considered to be delivered ad hoc to just above the inner horizon.

Selected correlates of white nursing students' attitudes toward black American patients.

Science.gov (United States)

Morgan, B S

1983-01-01

Multivariate analyses were used to examine the relationships between white nursing students' attitudes toward black American patients and variables selected within a theoretical framework of prejudice which included socialization factors and personality-based factors. The variables selected were: authoritarianism and self-esteem (personality-based factors), parents' attitudes toward black Americans, peer attitudes toward black Americans, interracial contact and socioeconomic status (socialization factors). The study also examined the differences in the relationship among white nursing students enrolled in baccalaureate degree, associate degree and diploma nursing programs. Data were collected from 201 senior nursing students enrolled in the three types of nursing programs in Rhode Island during the late fall and winter of 1979-1980. Although baccalaureate degree, associate degree and diploma students were similar in terms of peer attitudes toward black Americans, fathers' attitudes toward black Americans, self-esteem and attitudes toward black American patients, they were significantly different in terms of age, socioeconomic status, mothers' attitudes toward black Americans, interracial contact and authoritarianism. The major findings of this study indicate that the socialization explanation of prejudice is more significant than the personality-based explanation. The variables socioeconomic status, interracial contact and peer attitudes toward black Americans (all socialization variables) accounted for 22.0% of the total variance in attitudes toward black American patients for the total sample of nursing students. However, this relationship was not generalizable across the three different types of nursing programs.

Toward an understanding of the cerebral substrates of woman's orgasm.

Science.gov (United States)

Bianchi-Demicheli, Francesco; Ortigue, Stephanie

2007-09-20

The way women experience orgasm is of interest to scientists, clinicians, and laypeople. Whereas the origin and the function of a woman's orgasm remains controversial, the current models of sexual function acknowledge a combined role of central (spinal and cerebral) and peripheral processes during orgasm experience. At the central level, although it is accepted that the spinal cord drives orgasm, the cerebral involvement and cognitive representation of a woman's orgasm has not been extensively investigated. Important gaps in our knowledge remain. Recently, the astonishing advances of neuroimaging techniques applied in parallel with a neuropsychological approach allowed the unravelling of specific functional neuroanatomy of a woman's orgasm. Here, clinical and experimental findings on the cortico-subcortical pathway of a woman's orgasm are reviewed and compared with the neural basis of a man's orgasm. By defining the specific brain areas that sustain the assumed higher-order representation of a woman's orgasm, this review provides a foundation for future studies. The next challenge of functional imaging and neuropsychological studies is to understand the hierarchical interactions between these multiple cortical areas, not only with a correlation analysis but also with high spatio-temporal resolution techniques demonstrating the causal necessity, the temporal time course and the direction of the causality. Further studies using a multi-disciplinary approach are needed to identify the spatio-temporal dynamic of a woman's orgasm, its dysfunctions and possible new treatments.

Black Holes and Galactic Density Cusps I Radial Orbit Cusps and Bulges

CERN Document Server

Henriksen, Richard N; Macmillan, Joseph D

2011-01-01

Aims. In this paper we study density cusps made from radial orbits that may contain central black holes. The actual co-eval self-similar growth would not distinguish between the central object and the surroundings. Methods. To study the environment of an existing black hole we seek distribution functions that may contain a black hole and that retain at least a memory of self-similarity. We refer to the environment in brief as the 'bulge' or sometimes the 'halo'. This depends on whether the black hole is a true singularity dominating its halo or rather a core mass concentration that dominates a larger bulge. The hierarchy might extend to include galactic bulge and halo. Results.We find simple descriptions of simulated collisionless matter in the process of examining the presence of central masses. The Fridmann & Polyachenko distribution function describes co-eval growth of a bulge and black hole that might explain the observed mass correlation. Conclusions. We derive our results from first principles assum...

Troublesome Knowledge: A New Approach to Quality Assurance in Mental Health Nursing Education.

Science.gov (United States)

Leidl, Donald M

2018-01-01

Background Quality assurance and quality enhancement processes in nursing education are vital to the establishment of a strong program. Existing quality assurance methods in nursing education such as professional self-regulation and external examination rely on provincial and national nursing associations for evaluation, putting minimal responsibility and accountability on internal program examiners. Threshold concepts and troublesome knowledge provide a framework as outlined by Land that utilizes internal examiners from both student and faculty groups and represents an alternative to traditional quality assurance in nursing education. Purpose To identify troublesome mental health nursing content in a nursing curriculum by exploring students and faculty perspectives. Method A sequential mixed methods design that utilized surveys and focus groups to explore student and faculty perspectives on troublesome mental health nursing content. Results The project data were able to be organized into five main content themes that were identified as being troublesome: the spectrum of mental illness, therapeutic relationships and boundaries, praxis, professionalism in nursing, and brain chemistry and its management. Conclusion The findings from this project are unique to the program of review but show the potential of this new approach to quality assurance and program enhancement initiatives in nursing education.

Mouzon, Dawne M; McLean, Jamila S

2017-02-01

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

Black-hole production from ultrarelativistic collisions

International Nuclear Information System (INIS)

Rezzolla, Luciano; Takami, Kentaro

2013-01-01

Determining the conditions under which a black hole can be produced is a long-standing and fundamental problem in general relativity. We use numerical simulations of colliding self-gravitating fluid objects to study the conditions of black-hole formation when the objects are boosted to ultrarelativistic speeds. Expanding on the previous work, we show that the collision is characterized by a type-I critical behaviour, with a black hole being produced for masses above a critical value, M c , and a partially bound object for masses below the critical one. More importantly, we show for the first time that the critical mass varies with the initial effective Lorentz factor 〈γ〉 following a simple scaling of the type M c ∼ K〈γ〉 −1.0 , thus indicating that a black hole of infinitesimal mass is produced in the limit of a diverging Lorentz factor. Furthermore, because a scaling is present also in terms of the initial stellar compactness, we provide a condition for black-hole formation in the spirit of the hoop conjecture.

The status of a breastfeeding woman in labour law

Directory of Open Access Journals (Sweden)

Rabovanović Dragana

2016-01-01

Full Text Available The legal status of an employed woman who is breastfeeding is regulated by the special Occupational Safety and Health Act. This Act implies a number of specific measures developed to ensure that breastfeeding women and their children, as a particularly vulnerable group, are provided with a fuller support and protection. Thus, a breastfeeding woman is guaranteed the right to take one or more daily breaks to breastfeed her child, or the right to work shorter working hours on the daily basis, provided that she returns to work within a period of one year from the birth of her child. Moreover, a breastfeeding woman shall not be obliged to perform work which has been assessed as significantly risky to her health or to the health of her child. However, a complete occupational safety and health protection of a breastfeeding woman also implies protection from discrimination on the grounds of family responsibilities, as well as creating work environment where every employee can effectively exercise the right to fair working conditions, taking into consideration the risk of discrimination that the breastfeeding woman is exposed to and the difficulties she faces while exercising certain employment rights. This paper analyses the status of employed breastfeeding women in labour legislation in order to discuss and underscore the legal protection goals and to indicate the risks which endanger their dignity and wellbeing.

Quality assurance during site construction

During the time of planing and construction of a nuclear power plant, the following proceeding is approved: - the deliverer of a nuclear power plant provides the reports fixing the quality assurance program, it means that he is responsible to write the safety analysis report, the specifications for the erection of the components, the working manuals and specifications for testing (eg nondestr. testing) - the manufacturing of components or systems will be controlled by an own independent quality assurance group, provided that this group was checked by the quality assurance group of the applicant - the TUeV with its independent assessors will fix the requirements relating to quality assurance in its assessment. On this basis the examination of the applicants specifications, working manuals, testing specifications will be done. The efficiency of quality assurance at the manufacturer and at the applicant will be checked by the TUeV specialists by considering specifications of modifications, repairs or tolerances. A mean point of the quality assurance in Germany is the dynamic adjustment, of an action on the latest state of engineering or science. If there exists a change of rules or guidelines, the quality assurance requirements have to be fit on this state in so far as it is feasible from the technical point of view. (orig./RW)

The Needs of the Spanish Speaking Mujer [Woman] in Woman-Manpower Training Programs.

Nieto-Gomez, Anna

Although the Spanish Speaking woman is usually considered to be outside the labor market, 36 percent of the 52 percent Spanish Speaking women were in the labor force in March 1972. These women suffer economic-sexist discrimination due to ascription of work according to sex and race by a racial-sexual hierarchy existing within the traditional…

Statistical Entropy of Schwarzschild Black Holes

CERN Document Server

Englert, F

1998-01-01

The entropy of a seven dimensional Schwarzschild black hole of arbitrary large radius is obtained by a mapping onto a near extremal self-dual three-brane whose partition function can be evaluated. The three-brane arises from duality after submitting a neutral blackbrane, from which the Schwarzschild black hole can be obtained by compactification, to an infinite boost in non compact eleven dimensional space-time and then to a Kaluza-Klein compactification. This limit can be defined in precise terms and yields the Beckenstein-Hawking value up to a factor of order one which can be set to be exactly one with the extra assumption of keeping only transverse brane excitations. The method can be generalized to five and four dimensional black holes.

Authentication Assurance Levels

Kouzes, Richard T.; Cash, James R.; Devaney, David M.; Geelhood, Bruce D.; Hansen, Randy R.; Melton, Ronald B.; Pitts, W. Karl

2002-01-01

This Common Criteria approach has been applied to create a definition of Authentication Assurance Levels that can quantify the level of assurance reached for a system subject to a set of authentication procedures. The arms-control authentication application of the Common Criteria expands on more typical information security evaluations in that it must contend with information barriers and preclude sophisticated intentional subversion attempts.

CONSTRAINTS ON BLACK HOLE GROWTH, QUASAR LIFETIMES, AND EDDINGTON RATIO DISTRIBUTIONS FROM THE SDSS BROAD-LINE QUASAR BLACK HOLE MASS FUNCTION

International Nuclear Information System (INIS)

Kelly, Brandon C.; Hernquist, Lars; Siemiginowska, Aneta; Vestergaard, Marianne; Fan Xiaohui; Hopkins, Philip

2010-01-01

We present an estimate of the black hole mass function of broad-line quasars (BLQSOs) that self-consistently corrects for incompleteness and the statistical uncertainty in the mass estimates, based on a sample of 9886 quasars at 1 1 it is highly incomplete at M BH ∼ 9 M sun and L/L Edd ∼ BL > 150 ± 15 Myr for black holes at z = 1 with a mass of M BH = 10 9 M sun , and we constrain the maximum mass of a black hole in a BLQSO to be ∼3 x 10 10 M sun . Our estimated distribution of BLQSO Eddington ratios peaks at L/L Edd ∼ 0.05 and has a dispersion of ∼0.4 dex, implying that most BLQSOs are not radiating at or near the Eddington limit; however, the location of the peak is subject to considerable uncertainty. The steep increase in number density of BLQSOs toward lower Eddington ratios is expected if the BLQSO accretion rate monotonically decays with time. Furthermore, our estimated lifetime and Eddington ratio distributions imply that the majority of the most massive black holes spend a significant amount of time growing in an earlier obscured phase, a conclusion which is independent of the unknown obscured fraction. These results are consistent with models for self-regulated black hole growth, at least for massive systems at z > 1, where the BLQSO phase occurs at the end of a fueling event when black hole feedback unbinds the accreting gas, halting the accretion flow.

Metrology's role in quality assurance

International Nuclear Information System (INIS)

Zeederberg, L.B.

1982-01-01

Metrology, the science of measurement, is playing an increasing role in modern industry as part of an on-going quality assurance programme. At Escom, quality assurance was critical during the construction of the Koeberg nuclear facility, and also a function in controlling services provided by Escom. This article deals with the role metrology plays in quality assurance

Quality assurance of fuel elements

International Nuclear Information System (INIS)

Hoerber, J.

1980-01-01

The quality assurance activities for reactor fuel elements are based on a quality assurance system which implies the requirements resulting from the specifications, regulations of the authorities, national standards and international rules and regulations. The quality assurance related to production of reactor fuel will be shown for PWR fuel elements in all typical fabrication steps as conversion into UO 2 -powder, pelletizing, rodmanufacture and assembling. A wide range of destructive and nondestructive techniques is applied. Quality assurance is not only verified by testing techniques but also by process monitoring by means of parameter control in production and testing procedures. (RW)

Strong, female and Black: Stereotypes of African Caribbean women's body shape and their effects on clinical encounters.

Science.gov (United States)

Andrews, Nicole; Greenfield, Sheila; Drever, Will; Redwood, Sabi

2017-03-01

The aim of this article is to explore how tendencies to stereotype minority ethnic groups intersect with lay discourses about them in ways that can reproduce cultural prejudices and reinforce inequalities in access to services and health outcomes. Drawing upon Black feminist and cultural studies literature, we present a theoretical examination, the stereotypes of the Black woman as 'mammy' and 'matriarch'. We suggest that the influence of these two images is central to understanding the normalisation of the larger Black female body within African Caribbean communities. This representation of excess weight contradicts mainstream negative discourses of large bodies that view it as a form of moral weakness. Seeking to stimulate reflection on how unacknowledged stereotypes may shape clinical encounters, we propose that for Black women, it is the perception of strength, tied into these racial images of 'mammy' and 'matriarch' which may influence when or how health services or advice are both sought by them and offered to them. This has particular significance in relation to how body weight and weight management are/are not talked about in primary care-based interactions and what support Black women are/are not offered. We argue that unintentional bias can have tangible impacts and health outcomes for Black women and possibly other minority ethnic groups.

The quality assurance program at K ampersand S

International Nuclear Information System (INIS)

Slowey, T.W.

1993-01-01

K ampersand S operates the largest and one of the most comprehensive Accredited Dosimetry Calibration Laboratories (ADCLs) in the American Association of Physicists in Medicine (AAPM) secondary laboratory system. It offers calibrations covering energies from Grenz-Ray (0.03-mm Al) to cesium-137 and cobalt-60, brachytherapy source and well chamber calibrations for low-activity sources, and, recently, high-dose-rate iridium-192. The present Quality Assurance (QA) program at K ampersand S began with the AAPM Guidelines for Accreditation (Task Group No. 22 and No. 3, 1989) and grew over the past 10 years to include all aspects of providing a private, self-supporting calibration service from a free-standing independent facility. Some aspects of the QA program were prompted by the requirements of the nuclear power industry while other parts were from national consensus standards or the experiences of staff. Redundancy and teamwork are the most important characteristics of this QA program. K ampersand S has participated in a National Institute of Standards and Technology (NIST) measurement quality assurance (MQA) program since 1982, and, in recent years, an ADCL intralaboratory intercomparison was conducted by Task Group 3 of the Radiation Therapy Committee of the AAPM. One measure of the credibility of a QA program is consistent performance on the MQA program and the ADCL intercomparisons over the past 10 years. An equally important measure of the ability of a program to assure quality results is the frequency of reported errors

There are two important reasons for Software Quality Assurance (SQA) at Allied-Signal Inc., Kansas City Division (KCD): First, the benefits from SQA make good business sense. Second, the Department of Energy has requested SQA. This handbook is one of the first steps in a plant-wide implementation of Software Quality Assurance at KCD. The handbook has two main purposes. The first is to provide information that you will need to perform software quality assurance activities. The second is to provide a common thread to unify the approach to SQA at KCD. 2 figs.

'It's easier to talk to a woman'. Aspects of gender in Swedish telenursing.

Science.gov (United States)

Höglund, Anna T; Holmström, Inger

2008-11-01

To describe and explore gender aspects in telenursing as experienced by Swedish telenurses. Telenurses at call centres in Sweden offer triage recommendations and self-care advice to the general public over the telephone, on a wide range of health problems. The demands on telenurses are multifaceted and competence is needed in many fields such as nursing, pharmacology, psychology and communication. Previous studies have shown that telenurses encounter many ethical dilemmas and that some of these are to do with gender related issues. Most telenurses, as well as most callers, are women. It is, therefore, reasonable to believe that gender plays an important role in the work of telenurses. Descriptive and explorative qualitative design. A purposive sample of 12 female telenurses in Sweden participated in in-depth interviews twice during 2004-2005. The transcribed interviews were analysed inductively with a stepwise thematic method. Five themes emerged from the interviews, namely: female subordination in the family, disrespect in dialogue with female nurses, distrust in fathers' competence, reluctant male callers and woman-to-woman connection. Gender construction and cultural gender norms seem to be at work in the encounter between Swedish telenurses and callers. Questions of power relations, the picture of the mother/woman as the primary carer for small children and distrusting men in their parental role were particularly highlighted. Telenurses should be aware of the risk of stereotyping their dialogues with callers in a way that seems to fit better with female callers' ways of communicating. Clinical supervision based on reflective practice and peer reviews of calls might diminish this risk. Telenurses also need more training in handling overt or covert power messages based on male superiority.

Semiclassical S-matrix for black holes

CERN Document Server

Bezrukov, Fedor; Sibiryakov, Sergey

2015-01-01

We propose a semiclassical method to calculate S-matrix elements for two-stage gravitational transitions involving matter collapse into a black hole and evaporation of the latter. The method consistently incorporates back-reaction of the collapsing and emitted quanta on the metric. We illustrate the method in several toy models describing spherical self-gravitating shells in asymptotically flat and AdS space-times. We find that electrically neutral shells reflect via the above collapse-evaporation process with probability exp(-B), where B is the Bekenstein-Hawking entropy of the intermediate black hole. This is consistent with interpretation of exp(B) as the number of black hole states. The same expression for the probability is obtained in the case of charged shells if one takes into account instability of the Cauchy horizon of the intermediate Reissner-Nordstrom black hole. Our semiclassical method opens a new systematic approach to the gravitational S-matrix in the non-perturbative regime.

Magnetic monopoles near the black hole threshold

International Nuclear Information System (INIS)

Lue, A.; Weinberg, E.J.

1999-01-01

We present new analytic and numerical results for self-gravitating SU(2)-Higgs magnetic monopoles approaching the black hole threshold. Our investigation extends to large Higgs self-coupling, λ, a regime heretofore unexplored. When λ is small, the critical solution where a horizon first appears is extremal Reissner-Nordstroem outside the horizon but has a nonsingular interior. When λ is large, the critical solution is an extremal black hole with non-Abelian hair and a mass less than the extremal Reissner-Nordstroem value. The transition between these two regimes is reminiscent of a first-order phase transition. We analyze in detail the approach to these critical solutions as the Higgs expectation value is varied, and compare this analysis with the numerical results. copyright 1999 The American Physical Society

Threatened Selves and Differential Prejudice Expression by White and Black Perceivers

Science.gov (United States)

Shapiro, Jenessa R.; Mistler, Stephen A.; Neuberg, Steven L.

2010-01-01

Previous theorizing suggests that often-stigmatized individuals may be just as likely, if not more likely, than infrequently stigmatized individuals to protect self-regard by derogating members of low-status groups after receiving negative feedback from high-status others. Often-stigmatized individuals, however, can discount criticism from these high-status others as reflecting prejudice, thereby making outgroup derogation unnecessary as an esteem-protective strategy. Replicating past research, White participants in Experiment 1 expressed prejudices after receiving negative feedback from a White evaluator; as predicted, however, Black participants did not. In Experiment 2, participants instead received negative feedback from Black evaluators (evaluators more likely to threaten Black participants’ self-regard). Here, contrary to previous theorizing, Black participants expressed prejudices, not toward another low-status group, but toward high-status Whites. In all, findings reveal flaws in previous assumptions that frequently stigmatized individuals may be especially prone to devalue lower-status others after rejection or negative feedback from members of higher-status groups.

On attractor mechanism of AdS4 black holes

International Nuclear Information System (INIS)

Anabalón, Andrés; Astefanesei, Dumitru

2013-01-01

We construct a general family of exact non-extremal 4-dimensional black holes in AdS gravity with U(1) gauge fields non-minimally coupled to a dilaton and a non-trivial dilaton potential. These black holes can have spherical, toroidal, and hyperbolic horizon topologies. We use the entropy function formalism to obtain the near horizon data in the extremal limit. Due to the non-trivial self-interaction of the scalar field, the zero temperature black holes can have a finite horizon area even if only the electric field is turned on

Quantum Black Hole Model and HAWKING’S Radiation

Science.gov (United States)

Berezin, Victor

The black hole model with a self-gravitating charged spherical symmetric dust thin shell as a source is considered. The Schroedinger-type equation for such a model is derived. This equation appeared to be a finite differences equation. A theory of such an equation is developed and general solution is found and investigated in details. The discrete spectrum of the bound state energy levels is obtained. All the eigenvalues appeared to be infinitely degenerate. The ground state wave functions are evaluated explicitly. The quantum black hole states are selected and investigated. It is shown that the obtained black hole mass spectrum is compatible with the existence of Hawking’s radiation in the limit of low temperatures both for large and nearly extreme Reissner-Nordstrom black holes. The above mentioned infinite degeneracy of the mass (energy) eigenvalues may appeared helpful in resolving the well known information paradox in the black hole physics.

Errorless (re)learning of daily living routines by a woman with impaired memory and initiation: transferrable to a new home?

Science.gov (United States)

Ferland, Mark B; Larente, Johanne; Rowland, Julia; Davidson, Patrick S R

2013-01-01

To use errorless learning to train a memory- and initiation-impaired woman on two activities of daily living routines and then to transfer these routines to a new home. Single case quasi-experimental. Over 9 months, a young woman with an anterior cerebral haemorrhagic stroke (secondary to a ruptured arteriovenous malformation) was trained on routines of morning self-care and diabetes management, involving extensive practice on a structured series of steps with intervention as needed to prevent errors. Once routines were established, family members were trained in the supervision and rating of the routines at home. Following discharge, caregivers continued to monitor the routines daily for 3 months. Errorless learning of self-care and diabetes routines was successful. The routines were transferred to a new home environment and maintained at a near perfect level over a 3-month follow-up period. The patient remained severely memory-impaired, indicating that her functional gains were not attributable to any recovery of her memory abilities over time. This case offers evidence that even people with severe memory and initiation impairments can be trained on new routines using errorless learning and that, once learned, these routines can be carried out in novel contexts.

The reasonable woman standard: effects on sexual harassment court decisions.

Perry, Elissa L; Kulik, Carol T; Bourhis, Anne C

2004-02-01

Some federal courts have used a reasonable woman standard rather than the traditional reasonable man or reasonable person standard to determine whether hostile environment sexual harassment has occurred. The current research examined the impact of the reasonable woman standard on federal district court decisions, controlling for other factors found to affect sexual harassment court decisions. Results indicated that there was a weak relationship between whether a case followed a reasonable woman precedent-setting case and the likelihood that the court decision favored the plaintiff. The implications of our findings for individuals and organizations involved in sexual harassment claims are discussed.

Social Cognitive Correlates of Physical Activity in Black Individuals With Multiple Sclerosis.

Science.gov (United States)

Kinnett-Hopkins, Dominique; Motl, Robert W

2016-04-01

To examine variables from social cognitive theory as correlates of physical activity in black and white individuals with multiple sclerosis (MS). Cross-sectional. National survey. Black (n=151) and white (n=185) individuals with MS were recruited through the North American Research Committee on Multiple Sclerosis Registry. Not applicable. The battery of questionnaires included information on demographic and clinical characteristics, physical activity, exercise self-efficacy, function, social support, exercise outcome expectations, and exercise goal setting and planning. Black individuals with MS reported significantly lower levels of physical activity compared with white individuals with MS. Physical activity levels were significantly correlated with self-efficacy, outcome expectations, functional limitations as impediments, and goal setting in black participants with MS. The pattern and magnitude of correlations were comparable with those observed in white participants based on Fisher z tests. Researchers should consider applying behavioral interventions that target social cognitive theory variables for increasing physical activity levels among black individuals with MS.

Lemos, José P. S.; Zaslavskii, Oleg B.

2018-03-01

The membrane paradigm approach adopts a timelike surface, stretched out off the null event horizon, to study several important black hole properties. We use this powerful tool to give a direct derivation of the black hole mass formula in the static and stationary cases without and with electric field. Since here the membrane is a self-gravitating material system, we go beyond the usual applicability on test particles and test fields of the paradigm.

Hedges, D.

1984-01-01

The successful Chief Executive Officer (CEO) will have recognized the benefits of, and have implemented, a total quality assurance program. The quality assurance program will be adequately defined in policies and procedures such that managers and supervisors of each organizational element understand their primary and supporting roles in carrying out an effective quality assurance program. The traditional practice of having all quality assurance activities reside in a quality assurance organization will have been cast aside. Instead, the quality assurance activities necessary to achieve and assure the quality of the desired end product will have been defined and assigned to responsible organization elements. The quality assurance organization's primary role will be to define the total quality assurance program, insure that the achieving and assuring functions are assigned in policies and procedures, conduct training necessary to have management and supervisors understand the total quality assurance program, measure the effectiveness of the program and feedback measurement data for improvements in the program. The successful CEO will have implemented a quality assurance program that provides for a graded approach for application of the program based upon the importance of the intended use of the product or service. The successful CEO will rely heavily on the scheduled progress reports and assessments to measure the pulse of his organization's successes and improvement needs. This paper will describe suggested approaches for the Quality Assurance Manager to implement a quality assurance program which results in his corporation's CEO being a supporter of and a driving force in the implementation of the quality assurance program

Nuclear fuel quality assurance

International Nuclear Information System (INIS)

1976-01-01

Full text: Quality assurance is used extensively in the design, construction and operation of nuclear power plants. This methodology is applied to all activities affecting the quality of a nuclear power plant in order to obtain confidence that an item or a facility will perform satisfactorily in service. Although the achievement of quality is the responsibility of all parties participating in a nuclear power project, establishment and implementation of the quality assurance programme for the whole plant is a main responsibility of the plant owner. For the plant owner, the main concern is to achieve control over the quality of purchased products or services through contractual arrangements with the vendors. In the case of purchase of nuclear fuel, the application of quality assurance might be faced with several difficulties because of the lack of standardization in nuclear fuel and the proprietary information of the fuel manufacturers on fuel design specifications and fuel manufacturing procedures. The problems of quality assurance for purchase of nuclear fuel were discussed in detail during the seminar. Due to the lack of generally acceptable standards, the successful application of the quality assurance concept to the procurement of fuel depends on how much information can be provided by the fuel manufacturer to the utility which is purchasing fuel, and in what form and how early this information can be provided. The extent of information transfer is basically set out in the individual vendor-utility contracts, with some indirect influence from the requirements of regulatory bodies. Any conflict that exists appears to come from utilities which desire more extensive control over the product they are buying. There is a reluctance on the part of vendors to permit close insight of the purchasers into their design and manufacturing procedures, but there nevertheless seems to be an increasing trend towards release of more information to the purchasers. It appears that

Zhao, Ren; Zhang, Lichun; Li, Huaifan; Wu, Yueqin [Shanxi Datong University, Institute of Theoretical Physics, Department of Physics, Datong (China)

2010-01-15

We extend the classical Damour-Ruffini method and discuss Hawking radiation spectrum of high-dimensional rotating black hole using Tortoise coordinate transformation defined by taking the reaction of the radiation to the spacetime into consideration. Under the condition that the energy and angular momentum are conservative, taking self-gravitation action into account, we derive Hawking radiation spectrums which satisfy unitary principle in quantum mechanics. It is shown that the process that the black hole radiates particles with energy {omega} is a continuous tunneling process. We provide a theoretical basis for further studying the physical mechanism of black-hole radiation. (orig.)

2015-02-01

Advances in technical developments of genetic diagnostics for more than 50 years, as well as the fact that human genetic testing is usually performed only once in a lifetime, with additional impact for blood relatives, are determining the extraordinary importance of quality assurance in human genetic testing. Abidance of laws, directives, and guidelines plays a major role. This article aims to present the major laws, directives, and guidelines with respect to quality assurance of human genetic testing, paying careful attention to internal and external quality assurance. The information on quality assurance of human genetic testing was obtained through a web-based search of the web pages that are referred to in this article. Further information was retrieved from publications in the German Society of Human Genetics and through a PubMed-search using term quality + assurance + genetic + diagnostics. The most important laws, directives, and guidelines for quality assurance of human genetic testing are the gene diagnostics law (GenDG), the directive of the Federal Medical Council for quality control of clinical laboratory analysis (RiliBÄK), and the S2K guideline for human genetic diagnostics and counselling. In addition, voluntary accreditation under DIN EN ISO 15189:2013 offers a most recommended contribution towards quality assurance of human genetic testing. Legal restraints on quality assurance of human genetic testing as mentioned in § 5 GenDG are fulfilled once RiliBÄK requirements are followed.

Concepts of nuclear quality assurance

Randers, G.; Morris, P.A.; Pomeroy, D.

1976-01-01

While the safety record of the nuclear industry continues to be excellent, the forced outage rates for recent years continue to be 15% or more. Quality assurance, therefore, needs to be applied not only to nuclear safety matters, but to the goals of increased productivity and reduced construction and operating costs. Broadening the application of the general concept of quality assurance in this way leads to the introduction of reliability technology. The total activity might better be called reliability assurance. That effective quality assurance systems do pay off is described by examples from the utility industry, from a manufacturer of instruments and systems and from the experience of Westinghouse Electric Company's manufacturing divisions. The special situation of applying quality assurance to nuclear fuel is discussed. Problems include the lack of a fully developed regulatory policy in this area, incomplete understanding of the mechanism for pellet-clad interaction failures, incomplete access to manufacturers design and process information, inability to make desirable changes on a timely basis and inadequate feedback of irradiation experience.

We construct a general family of exact non-extremal 4-dimensional black holes in AdS gravity with U(1) gauge fields non-minimally coupled to a dilaton and a non-trivial dilaton potential. These black holes can have spherical, toroidal, and hyperbolic horizon topologies. We use the entropy function formalism to obtain the near horizon data in the extremal limit. Due to the non-trivial self-interaction of the scalar field, the zero temperature black holes can have a finite horizon area even if only the electric field is turned on.

Quality assurance in plant engineering

International Nuclear Information System (INIS)

1977-01-01

Quality assurance is defined as the intentional and systematic activity carried out to obtain such reliability that the functions of nuclear power generating plants are demonstrated during the plant operation, and the section in charge has the role to organize, adjust and communicate so that the related sections can work smoothly. There are many documents concerning the quality assurance, such as quality assurance basic program, quality assurance manual, quality control plan and its manual and many specifications, etc. The content of the quality assurance is different for every step of plant planning such as at inquiry and order receiving, and prior to manufacturing, for example, inspection specification being decided for the material and the welded parts of classified pipings at the step of order receiving. Document management, engineering schedule and the custody of quality records are also quality assurance activities. Design management is controlled step by step; plant planning including safety analysis, overall layout plan, conceptual design of buildings, aseismatic design guide, heat balance and so on, system design mainly with system description, piping design including piping specification, standard dimensions of edge preparation, piping and valve lists, inspection manual, etc., detailed design, standardization of piping and design review, etc. are explained. The management of the intermediate between soft and hard parts consists of the quality check for material manufacturers and shipment inspection, etc. (Nakai, Y.)

The aim of this study was to investigate the influence of Black identity on wellbeing and health behaviors. Data from the third year (wave) of a longitudinal cohort study (N = 1316) from a large, majority Black, Protestant church of 16,000 members located in Houston, Texas, were used to conduct secondary data analyses. Univariate analyses were used to obtain participants' sociodemographic and health characteristics. ANCOVA and linear regression analyses and Bonferroni adjustments were used to examine the influence of the centrality, public and private regard aspects of Black identity as measured by the Multidimensional Inventory of Black Identity subscales on wellbeing (CES-D scores and self-reported general health) and health behaviors (diet and physical activity levels). Associations were noted between fruit consumption and centrality (F (95,1216) = 2.27) p = .046); soda consumption and private regard (F (5,1214) = 3.04; p = .010); public regard (F (2,1186) = 4.70; p = .009) and physical activity levels; self-reported general health status and private (F (4,1219) = 4.78; p = .001) and public regard (F (4,1211) = 8.53; p identity remain an important factor to consider in addressing health disparities. Racial identity influences mental health, general health, diet and the physical activity levels. Utilizing identity congruent health promotion interventions may positively impact mental, exercise levels, self-reported general health and diet.

Investigating Supermassive Black Hole Spin at Different Redshift

Science.gov (United States)

Sinanan-Singh, Jasmine

2018-01-01

Supermassive black hole (SMBH) spin encodes vital information about the history of SMBH growth. High spins indicate a history of growth through large mass accretion events, which spin-up the black hole; Intermediate spins indicate a history of galactic mergers, which don't tend to systemcatically spin-up or spin-down black holes; low spins are attributed to successive, small accretion events with random orientations. Examining spin over different redshifts will help us understand the relative growth of SMBHs by mergers or accretion over cosmic time, an important part of understanding how SMBHs and their host galaxies co-evolved over time. To study spin, we compute the Fe K alpha emission line from the X-ray spectra of AGN sources in the Chandra-COSMOS Legacy Survey. We stack rest frame AGN spectra to improve the signal-to-noise ratio since the photon counts are low for individual spectra, and then average the spectra using an unwieghted mean. Our method is derived from Corral et al. (2008). We test our method on the two brightest sources in the COSMOS Survey and compute the rest frame average Fe K alpha emission line for different redshift bins.

'With woman' philosophy: examining the evidence, answering the questions.

Science.gov (United States)

Carolan, Mary; Hodnett, Ellen

2007-06-01

'With woman', 'woman centred' and 'in partnership with women' are new terms associated with midwifery care in Australia, and the underlying philosophy has emerged both as an antidote to the medicalisation of pregnancy and in a bid to reacquaint women with their natural capacity to give birth successfully and without intervention. A reorientation of midwifery services in the 1990s, a shift towards midwifery-led care (MLC) and the subsequent introduction of direct entry midwifery programs all contributed to this new direction. Central concepts are a focus on the childbearing woman and a valuing of women's experiences. While this philosophical re-alignment has been applauded by many midwives in terms of maternal empowerment and improved autonomy for midwives, there are nonetheless some concerns that, with its emphasis on normality, midwifery-led care is in danger of becoming an exclusionary model. Particular concerns include meeting the needs of a growing cohort of women, those with 'high risk' pregnancies, and the educational adequacy of direct entry midwifery programs. To date, there has been no thorough evaluation of this emerging midwifery philosophy in Australia. In order to open the debate, this paper aims to initiate a discussion of 'with woman' midwifery care as it applies to Australian practice.

2018-05-01

We integrate numerically axially symmetric stationary Einstein equations describing self-gravitating disks around spinless black holes. The numerical scheme is based on a method developed by Shibata, but contains important new ingredients. We derive a new general-relativistic Keplerian rotation law for self-gravitating disks around spinning black holes. Former results concerning rotation around spinless black holes emerge in the limit of a vanishing spin parameter. These rotation curves might be used for the description of rotating stars, after appropriate modification around the symmetry axis. They can be applied to the description of compact torus-black hole configurations, including active galactic nuclei or products of coalescences of two neutron stars.

Black Hole Universe Model and Dark Energy

Zhang, Tianxi

2011-01-01

Considering black hole as spacetime and slightly modifying the big bang theory, the author has recently developed a new cosmological model called black hole universe, which is consistent with Mach principle and Einsteinian general relativity and self consistently explains various observations of the universe without difficulties. According to this model, the universe originated from a hot star-like black hole and gradually grew through a supermassive black hole to the present universe by accreting ambient material and merging with other black holes. The entire space is infinitely and hierarchically layered and evolves iteratively. The innermost three layers are the universe that we lives, the outside space called mother universe, and the inside star-like and supermassive black holes called child universes. The outermost layer has an infinite radius and zero limits for both the mass density and absolute temperature. All layers or universes are governed by the same physics, the Einstein general relativity with the Robertson-Walker metric of spacetime, and tend to expand outward physically. When one universe expands out, a new similar universe grows up from its inside black holes. The origin, structure, evolution, expansion, and cosmic microwave background radiation of black hole universe have been presented in the recent sequence of American Astronomical Society (AAS) meetings and published in peer-review journals. This study will show how this new model explains the acceleration of the universe and why dark energy is not required. We will also compare the black hole universe model with the big bang cosmology.

An integrated quality assurance system has necessitated carrying out quality assurance programs in a systematic manner because the opportunities to expand business in overseas markets have increased since the export of a nuclear power plant to UAE in 2009. In this study, we use PDCA method to systematically analyze the quality assurance procedures that were used in previous projects for constructing nuclear power plants. We reached a classification system of quality assurance processes at each phase of nuclear power plant construction by integrating similar work related to quality such as planning, design, equipment manufacturing, construction and start-up. We also established a hierarchy of quality assurance processes to develop an integrated quality assurance system as a technology goal to be developed later. To obtain most updated quality assurance activities, a quality assurance process is structured by integrating similar works analyzed from quality assurance procedures through PDCA cycle method. At the implementation phase of Hierarchy of quality processes and sequence of processes for constructing nuclear power plant are established in this study. Integrated quality assurance system is to be developed by connecting organizations as well as stakeholders such as owners, Architect engineering, suppliers, contractors, and sub-contractors to carry out assigned work efficiently

Tool Use Within NASA Software Quality Assurance

Shigeta, Denise; Port, Dan; Nikora, Allen P.; Wilf, Joel

As space mission software systems become larger and more complex, it is increasingly important for the software assurance effort to have the ability to effectively assess both the artifacts produced during software system development and the development process itself. Conceptually, assurance is a straightforward idea - it is the result of activities carried out by an organization independent of the software developers to better inform project management of potential technical and programmatic risks, and thus increase management's confidence in the decisions they ultimately make. In practice, effective assurance for large, complex systems often entails assessing large, complex software artifacts (e.g., requirements specifications, architectural descriptions) as well as substantial amounts of unstructured information (e.g., anomaly reports resulting from testing activities during development). In such an environment, assurance engineers can benefit greatly from appropriate tool support. In order to do so, an assurance organization will need accurate and timely information on the tool support available for various types of assurance activities. In this paper, we investigate the current use of tool support for assurance organizations within NASA, and describe on-going work at JPL for providing assurance organizations with the information about tools they need to use them effectively.

Rotating hairy black holes in arbitrary dimensions

Science.gov (United States)

Erices, Cristián; Martínez, Cristián

2018-01-01

A class of exact rotating black hole solutions of gravity nonminimally coupled to a self-interacting scalar field in arbitrary dimensions is presented. These spacetimes are asymptotically locally anti-de Sitter manifolds and have a Ricci-flat event horizon hiding a curvature singularity at the origin. The scalar field is real and regular everywhere, and its effective mass, coming from the nonminimal coupling with the scalar curvature, saturates the Breitenlohner-Freedman bound for the corresponding spacetime dimension. The rotating black hole is obtained by applying an improper coordinate transformation to the static one. Although both spacetimes are locally equivalent, they are globally different, as it is confirmed by the nonvanishing angular momentum of the rotating black hole. It is found that the mass is bounded from below by the angular momentum, in agreement with the existence of an event horizon. The thermodynamical analysis is carried out in the grand canonical ensemble. The first law is satisfied, and a Smarr formula is exhibited. The thermodynamical local stability of the rotating hairy black holes is established from their Gibbs free energy. However, the global stability analysis establishes that the vacuum spacetime is always preferred over the hairy black hole. Thus, the hairy black hole is likely to decay into the vacuum one for any temperature.

The objective of this descriptive, cross-sectional study was to evaluate the self-esteem of 127 pregnant women seen in a prenatal care program conducted in a public school hospital. Data collection was performed using the Rosenberg's Self-esteem Scale; unsatisfactory self-esteem was related to socio-demographic and health variables of the pregnant woman, and to the presence or absence of support systems. Descriptive and univariate statistical analysis were used to assess possible associations. Pregnant women who had low scores for self-esteem were 60% of all subjects. As for the sociodemographic data, women with fewer years of education presented higher frequency of lower self-esteem scores, which disagrees with other studies. Pregnant women who report having an unplanned pregnancy presented higher prevalence of low self-esteem than those who reported having planned their pregnancy. The lack of support from the partner to look after the baby was also associated to the pregnant women's low self-esteem. Other associations between variables were not statistically significant.

Owing to lack of governmental regulation of veterinary laboratory performance, veterinarians ideally should demonstrate a commitment to self-monitoring and regulation of laboratory performance from within the profession. In response to member concerns about quality management in veterinary laboratories, the American Society for Veterinary Clinical Pathology (ASVCP) formed a Quality Assurance and Laboratory Standards (QAS) committee in 1996. This committee recently published updated and peer-reviewed Quality Assurance Guidelines on the ASVCP website. The Quality Assurance Guidelines are intended for use by veterinary diagnostic laboratories and veterinary research laboratories that are not covered by the US Food and Drug Administration Good Laboratory Practice standards (Code of Federal Regulations Title 21, Chapter 58). The guidelines have been divided into 3 reports on 1) general analytic factors for veterinary laboratory performance and comparisons, 2) hematology and hemostasis, and 3) clinical chemistry, endocrine assessment, and urinalysis. This report documents recommendations for control of general analytical factors within veterinary clinical laboratories and is based on section 2.1 (Analytical Factors Important In Veterinary Clinical Pathology, General) of the newly revised ASVCP QAS Guidelines. These guidelines are not intended to be all-inclusive; rather, they provide minimum guidelines for quality assurance and quality control for veterinary laboratory testing. It is hoped that these guidelines will provide a basis for laboratories to assess their current practices, determine areas for improvement, and guide continuing professional development and education efforts. ©2010 American Society for Veterinary Clinical Pathology.

Bovine ketosis is a rare cause of metabolic acidosis. It is a starvation ketosis that appears in lactating woman. A 29-year-old woman had a previous gastric surgery one month ago while breastfeeding her 6-month child. She presented to emergency with dyspnea, fatigue, weight loss and anorexia. The explorations revealed a serious metabolic acidosis with a high anion gap, for which all other causes have been eliminated. A restrictive diet in lactating patients is a major risk of ketosis or bovine ketosis. Medico-surgical treatment of obesity during lactation seems unreasonable. Breastfeeding should be systematically sought before a medical and surgical management of obesity. With the spread of bariatric surgery, starvation ketosis is a cause of metabolic acidosis not to ignore. Copyright © 2015 Société nationale française de médecine interne (SNFMI).

Looking for the invisible universe - Black matter, black energy, black holes

International Nuclear Information System (INIS)

Elbaz, David

2016-01-01

As the discovery of the expansion of the universe and of black holes put the study of cosmology into question again because it now refers to invisible things such as black holes, black energy and black matter, the author proposes an other view on the universe within such a context. He first discusses these three enigmas of black matter, black energy and black holes. In a second part, he addresses, discusses and comments five illusions: the Uranian illusion (questions of the existence of an anti-world, of black matter temperature), the Mercurian illusion (quantum gravity, the string theory), the Martian illusion (a patchwork universe, the illusion of the infinite), the cosmic Maya (the John Wheeler's cup, the holographic universe), and the narcissistic illusion

Situating Cyberzone: Black lesbian identity in comics.

Howard, Sheena C

2018-04-25

Cyberzone is a fitting place to start any discussion around Black lesbian identity in comics, as it is the first comic book that this researcher could find which features a Black lesbian female lead superheroine. Cyberzone was self-published by Jimmie Robinson in 1994 and later re-vamped into a mini-comic series called Amanda and Gunn with Image Comics. First, this article deconstructs Cyberzone through the lens of Cultural Prism Theory (CPT). Second, this article situates Cyberzone within the framework of CPT to address Cyberzone's place within the comic book ecosystem. Finally, this essay offers a close reading of Cyberzone, issues #1-#4, against the backdrop of the intersectional framework Black Queer Identity Matrix. During this process, the researcher demonstrates how Cyberzone is a powerful site of resistant cultural commentary.

Development of Candidate Reference Materials of Endosulfan Sulfate and Bifenthrin in Black Tea

Directory of Open Access Journals (Sweden)

Nurhani Aryana

2016-03-01

Full Text Available The candidate reference materials of endosulfan sulfate and bifenthrin in black tea have been developed according to the requirements of ISO Guide 34 and 35. Preparation of candidate material includes grinding and sieving of the black tea leaves, spiking the black tea powder by both analytes, homogenization, and bottling. Homogeneity and short-term stability test were performed using a GC-µECD instrument. Meanwhile, the characterization was carried out by a collaborative study using both of GC-µECD and GC-MS instruments. The uncertainty budget was evaluated from sample inhomogeneity, short-term instability and variability in the characterization procedure. In a dry mass fraction, endosulfan sulfate was assigned to be 491 µg kg-1 with a relative expanded uncertainty of ± 33.2%, and bifenthrin was assigned to be 937 µg kg-1 with a relative expanded uncertainty of ± 18.5%. The candidate reference materials are aimed to support the need of matrix CRM especially for the measurement of pesticide residue for quality assurance work done by laboratories in Indonesia.

An approach to total quality assurance

International Nuclear Information System (INIS)

Archer, L.G.

1976-01-01

Total Quality Assurance must be based on amalgamating three quality functions: effective quality control, competent inspection, and regularly audited Quality Assurance programmes. In applying these functions the fuel supplier must regard each of his sub-contractors as part of his own works and ensure a common policy of motivated Quality Assurance throughout his own works and those of his suppliers.

Additional study results related to major factors for positive and negative attitudes toward quality assurance will be presented

[Integrated quality assurance].

Science.gov (United States)

Bögel, K; Stöhr, K

1994-07-01

The definition of terms and connotation of "Quality", "Quality Assurance" and "Integration" lead to an analysis and understanding of inhibiting and fostering factors of the "Health Triad" of people, animals and environment. Although "Quality" is largely or ultimately determined by the consumer, there are considerable differences as this term is applied by (a) the individual consumer, (b) the dynamic producer defending or gaining markets, (c) those engaged in traditional product manufacturing, or (d) governments setting (minimum) requirements for the sake of free trade. "Quality Assurance" offers cooperation of partners all along the food chain from "pasture to table". The managerial process turned into a continuum of responsibility and agreement on processes and product characteristics. This overcomes the disadvantages of strategies stressing distinct defense barriers. In practice this philosophy of a predominant role of defence barriers proved largely partnership destructive, in that it permitted to shift responsibilities for failures and to claim administrative competence according to momentary situations and interests. "Integrated Quality Assurance" means mutual agreement of two or more partners along the food chain (e. g. feed producers, farmers, animal health industry, veterinarians and food processors) on product characteristics and production methods. It involves essential system elements including facilities, materials, manpower, information, transport, management etc. Different principles and procedures of quality assurance have been introduced in practice, including agriculture and food processing. These different approaches are not mutually exclusive but largely of complementary nature.(ABSTRACT TRUNCATED AT 250 WORDS)

Quality assurance considerations in nuclear waste management

International Nuclear Information System (INIS)

Delvin, W.L.

1982-01-01

Proper use of quality assurance will provide the basis for an effective management control system for nuclear waste management programs. Control is essential for achieving successful programs free from costly losses and failures and for assuring the public and regulators that the environment and health and safety are being protected. The essence of quality assurance is the conscientious use of planned and systematic actions, based on selecting and applying appropriate requirements from an established quality assurance standard. Developing a quality assurance program consists of using knowledge of the technical and managerial aspects of a project to identify and evaluate risks of loss and failure and then to select appropriate quality assurance requirements that will minimize the risks. Those requirements are integrated into the project planning documents and are carried out as specific actions during the life of the project

Raab, Stephen S

2006-05-01

Anatomic pathology laboratories use several quality assurance tools to detect errors and to improve patient safety. To review some of the anatomic pathology laboratory patient safety quality assurance practices. Different standards and measures in anatomic pathology quality assurance and patient safety were reviewed. Frequency of anatomic pathology laboratory error, variability in the use of specific quality assurance practices, and use of data for error reduction initiatives. Anatomic pathology error frequencies vary according to the detection method used. Based on secondary review, a College of American Pathologists Q-Probes study showed that the mean laboratory error frequency was 6.7%. A College of American Pathologists Q-Tracks study measuring frozen section discrepancy found that laboratories improved the longer they monitored and shared data. There is a lack of standardization across laboratories even for governmentally mandated quality assurance practices, such as cytologic-histologic correlation. The National Institutes of Health funded a consortium of laboratories to benchmark laboratory error frequencies, perform root cause analysis, and design error reduction initiatives, using quality assurance data. Based on the cytologic-histologic correlation process, these laboratories found an aggregate nongynecologic error frequency of 10.8%. Based on gynecologic error data, the laboratory at my institution used Toyota production system processes to lower gynecologic error frequencies and to improve Papanicolaou test metrics. Laboratory quality assurance practices have been used to track error rates, and laboratories are starting to use these data for error reduction initiatives.

New coordinates for BTZ black hole and Hawking radiation via tunnelling

International Nuclear Information System (INIS)

Liu Wenbiao

2006-01-01

Hawking radiation can usefully be viewed as a semi-classical tunnelling process that originates at the black hole horizon. For the stationary axisymmetric BTZ black hole, a generalized Painleve coordinate system (Painleve-BTZ coordinates) is introduced, and Hawking radiation as tunnelling under the effect of self-gravitation is investigated. The corrected radiation is obtained which is not precise thermal spectrum. The result is consistent with the underlying unitary theory. Moreover, Bekenstein-Hawking entropy of BTZ black hole is not necessarily corrected when we choose appropriate coordinate system to study the tunnelling effect

Controlling images: How awareness of group stereotypes affects Black women's well-being.

Science.gov (United States)

Jerald, Morgan C; Cole, Elizabeth R; Ward, L Monique; Avery, Lanice R

2017-10-01

This paper presents research exploring how stereotypes that are simultaneously racialized and gendered affect Black women. We investigated the mental and physical health consequences of Black women's awareness that others hold these stereotypes and tested whether this association was moderated by the centrality of racial identity. A structural equation model tested among 609 young Black women revealed that metastereotype awareness (i.e., being aware that others hold negative stereotypes of one's group) predicted negative mental health outcomes (e.g., depression, anxiety, hostility), which, in turn, predicted diminished self-care behaviors and greater drug and alcohol use for coping. High racial centrality exacerbated the negative association between metastereotype awareness and self-care. We discuss implications of the findings for clinical practice and for approaches to research using intersectionality frameworks. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Waste Management Quality Assurance Plan

International Nuclear Information System (INIS)

2006-01-01

The WMG QAP is an integral part of a management system designed to ensure that WMG activities are planned, performed, documented, and verified in a manner that assures a quality product. A quality product is one that meets all waste acceptance criteria, conforms to all permit and regulatory requirements, and is accepted at the offsite treatment, storage, and disposal facility. In addition to internal processes, this QA Plan identifies WMG processes providing oversight and assurance to line management that waste is managed according to all federal, state, and local requirements for waste generator areas. A variety of quality assurance activities are integral to managing waste. These QA functions have been identified in the relevant procedures and in subsequent sections of this plan. The WMG QAP defines the requirements of the WMG quality assurance program. These requirements are derived from Department of Energy (DOE) Order 414.1C, Quality Assurance, Contractor Requirements Document, the LBNL Operating and Assurance Program Plan (OAP), and other applicable environmental compliance documents. The QAP and all associated WMG policies and procedures are periodically reviewed and revised, as necessary, to implement corrective actions, and to reflect changes that have occurred in regulations, requirements, or practices as a result of feedback on work performed or lessons learned from other organizations. The provisions of this QAP and its implementing documents apply to quality-affecting activities performed by the WMG; WMG personnel, contractors, and vendors; and personnel from other associated LBNL organizations, except where such contractors, vendors, or organizations are governed by their own WMG-approved QA programs

Minoan Civilization (3000-1150 BC) was the first European civilization on the GREEK island of Crete. Fabulous architectonical constructions like great palaces, wonderful frescoes, and pottery as well as jewellery characterize this amazing civilization. According to all existing descriptions from ancient Greek historians and philosophers like Plato, Thucydides, Strabon but also from all the archaeological findings men and women lived freely and peacefully participating equal in all daily activities, sports, and games. The women were predominating. Minoan women enjoyed a higher social status than other women in later civilizations. Investigation of all the existing data concerning the Minoan culture. Archaeological databases, as well as data from the National University of Athens and other Greek historical institutions were collected and analyzed in order to present the Minoan culture. The Minoic civilization represents a paradigm of a well being society in which the woman played a dominant role. She was the 'mother' but also the 'active woman', who participated in all city activities. Four thousand years later a prototype of a society in which the role of the mother was recognized in an admirably way remains a magnificent paradigm.

Hrabosky, Joshua I; Grilo, Carlos M

2007-01-01

The current study examined body image concerns and eating disordered behaviors in a community sample of Black and Hispanic women. In addition, this study explored whether there are ethnic differences in the correlates or in the prediction of body image concerns. Participants were 120 (67 Black and 53 Hispanic) women who responded to advertisements to participate in a study of women and health. Participants completed a battery of established self-report measures to assess body image, eating disordered behaviors, and associated psychological domains. Black and Hispanic women did not differ significantly in their self-reports of body image, eating disordered behaviors, or associated psychological measures. Comparisons performed separately within both ethnic groups revealed significant differences by weight status, with a general graded patterning of greater concerns in obese than overweight than average weight groups. In terms of predicting body image, multiple regression analyses testing a number of variables, including BMI, performed separately for Black and Hispanic women revealed that eating concern and depressive affect were significant predictors of body image concern for both groups. Overall, Black and Hispanic women differed little in their self-reports of body image, eating-disordered features, and depressive affect. Higher weight was associated with a general pattern of increased body image concerns and features of eating disorders in both groups and with binge eating in Black women. Eating concerns and depressive affect emerged as significant independent predictors of body image for both ethnic groups.

Sofia Ionescu, the first woman neurosurgeon in the world.

The authors present the activity of Mrs. Sofia Ionescu, the one female surgeon who was nominated as the first woman neurosurgeon in the world. Sofia Ionescu worked in the field of neurosurgery for 47 years, performing all the known neurosurgical procedures of the time. She made herself known through her incredible surgical skill and her enormous work power. Due to her incredible modesty and workload, she never participated at international congresses or manifestations. The nomination as first woman neurosurgery took place in Marrakech, Morocco, during the 2005 WFNS Congress. Although some claim that Diana Beck was the first woman neurosurgeon in the world, our theory suggests otherwise. The first documented surgical intervention performed by Diana Beck dates to 1952. Sofia Ionescu operated for the first time on a human brain as early as 1944. Furthermore, Diana Beck's actions surfaced in the year 1947, long after the war had ended and Sofia Ionescu had become a neurosurgeon. Copyright © 2013. Published by Elsevier Inc.

Harriet Brooks: Canada's First Woman Physicist

2004-03-01

During those early halcyon days of the study of radioactivity, one young Canadian woman, Harriet Brooks, joined Ernest Rutherford's group as his first research student. Later, she joined J.J. Thomson's group in Cambridge and, finally, Marie Curie's group in Paris. During her short research career, she made several important contributions to science. She investigated the nature of 'emanation' from radium; discovered that radioactive substances could undergo successive decay; and first reported the recoil of the radioactive atom. Much of this research was published under her name alone though Rutherford made extensive reference to her discoveries in his Bakerian lecture of 1904. Brooks life is of interest not only in what she accomplished, but also in the challenges she faced as a pioneering woman scientist in the early part of the twentieth century. In the presentation we will blend the account of her life and work with the societal context. This work was accomplished jointly with Marelene F. Rayner-Canham.

This article is a systhematic literature review including the period from 1994 to 2009, whose objective was to discuss the aged woman's vulnerability in relation to Acquired Imunodeficiency Syndrome (Aids). The search for scientific texts was accomplished in the following databases: Biblioteca Virtual em Saúde, Scientific Eletronic Library Online (SciELO), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) and Medical Literature Analysis and Retrieval System Online (MEDLINE). The descriptors used were vulnerability, woman and Aids. Eighteen texts were analyzed, including articles in scientific journals, thesis and dissertations. As a conclusion, it was noted that aged women and vulnerability to Aids are directly related, through gender characteristics including submission and that were built historical and socially. We consider as fundamental the development of studies which may generate publications accessible to women, in order to help them see themselves as persons vulnerable to Aids contagion just for being women.

Black hole growth in the early Universe is self-regulated and largely hidden from view.

The formation of the first massive objects in the infant Universe remains impossible to observe directly and yet it sets the stage for the subsequent evolution of galaxies. Although some black holes with masses more than 10(9) times that of the Sun have been detected in luminous quasars less than one billion years after the Big Bang, these individual extreme objects have limited utility in constraining the channels of formation of the earliest black holes; this is because the initial conditions of black hole seed properties are quickly erased during the growth process. Here we report a measurement of the amount of black hole growth in galaxies at redshift z = 6-8 (0.95-0.7 billion years after the Big Bang), based on optimally stacked, archival X-ray observations. Our results imply that black holes grow in tandem with their host galaxies throughout cosmic history, starting from the earliest times. We find that most copiously accreting black holes at these epochs are buried in significant amounts of gas and dust that absorb most radiation except for the highest-energy X-rays. This suggests that black holes grew significantly more during these early bursts than was previously thought, but because of the obscuration of their ultraviolet emission they did not contribute to the re-ionization of the Universe.

The IAEA directed extensive efforts during the years 1991 to 1995 to the integral revision of all NUSS quality assurance publications, which were approved and issued as Safety Series No.50-C/SG-Q, Quality Assurance for Safety in Nuclear Power Plants and other Nuclear Installations (1996). When these quality assurance publications were developed, their prime focus was on requirements against which work performed by the licensees could be measured and assessed by the regulatory bodies. In this way, they only helped to facilitate the functions of regulators. No requirements or recommendations were provided on how the regulators should ensure the effective implementation of their own activities. The present publication is a first attempt to collect, integrate and offer available experience to directly support performance of regulatory activities. It presents a comprehensive compilation on the application of quality assurance principles and methods by regulatory bodies to their activities. The aim is consistent good performance of regulatory activities through a systematic approach

Black Hole Universe Model for Explaining GRBs, X-Ray Flares, and Quasars as Emissions of Dynamic Star-like, Massive, and Supermassive Black Holes

Science.gov (United States)

Zhang, Tianxi

2014-01-01

Slightly modifying the standard big bang theory, the author has recently developed a new cosmological model called black hole universe, which is consistent with Mach’s principle, governed by Einstein’s general theory of relativity, and able to explain all observations of the universe. Previous studies accounted for the origin, structure, evolution, expansion, cosmic microwave background radiation, and acceleration of the black hole universe, which grew from a star-like black hole with several solar masses through a supermassive black hole with billions of solar masses to the present state with hundred billion-trillions of solar masses by accreting ambient matter and merging with other black holes. This study investigates the emissions of dynamic black holes according to the black hole universe model and provides a self-consistent explanation for the observations of gamma ray bursts (GRBs), X-ray flares, and quasars as emissions of dynamic star-like, massive, and supermassive black holes. It is shown that a black hole, when it accretes its ambient matter or merges with other black holes, becomes dynamic. Since the event horizon of a dynamic black hole is broken, the inside hot (or high-frequency) blackbody radiation leaks out. The leakage of the inside hot blackbody radiation leads to a GRB if it is a star-like black hole, an X-ray flare if it is a massive black hole like the one at the center of the Milky Way, or a quasar if it is a supermassive black hole like an active galactic nucleus (AGN). The energy spectra and amount of emissions produced by the dynamic star-like, massive, and supermassive black holes can be consistent with the measurements of GRBs, X-ray flares, and quasars.

To investigate how exposure to sex, alcohol and violent content in mainstream and Black-oriented movies relates to corresponding adolescent behavior among Black youth from the United States and whether those relationships are moderated by ethnic identity. The present study uses survey data from an online sample of 1000 Black adolescents and content analysis ratings on top-grossing 2014 films and 2013/2014 Black-oriented films. Content-specific exposure measures for alcohol, sexual activity, and violence were calculated from self-reported exposure data and content analysis ratings. Regression analyses estimated the associations among exposures to risky health content in mainstream and Black-oriented films and adolescent behaviors as well as moderation by ethnic group identity. Black adolescents were mostly unaffected by exposure to risk portrayals in mainstream films, but exposure to risk in Black-oriented films was related to their behavior in all three domains. Strong group identity strengthened the relationship between exposure to sex in Black-oriented and mainstream films depending on the sexual outcome. The type of movie (i.e., mainstream or Black-oriented) through which Black adolescents are exposed to risky health portrayals is important for understanding its relationship to their behavior, and variations by ethnic identity were limited to sex content. Future research should identify the mechanisms through which risk content in Black-oriented films is associated with Black adolescents' risky behaviors to determine how media influence contributes to behavioral disparities among youth.

The mission of the Nuclear Research Center is to be the leading national institution that conducts both training and research/development to obtain new information and results, to develop new methodology and technology in fundamental and applied nuclear physics, and also to develop equipment and devices. In order to implement quality management in nuclear technology training activities and conduct quality assurance, the Bachelor's education program has been required to create a self evaluation and the first copy of the report had been produced. It is a common perception that the main mechanism of higher education quality assurance is the internal quality management, and quality external monitoring. Therefore a general model used in most countries for higher education quality assurance. This model's main device is internal and external evaluation. The external evaluation has responsibility to improve accreditation, responsibility/commitment. Based on its self evaluation, the organization will develop its quality plan and, combined with external evaluation conclusions, will be lead toward quality improvement. The most important part of quality assessment is the use of external experts' assessment. Our nuclear research center is the only educational and research institution in the country, and, thus, it is impossible to find respectable independent experts (who do not get involved in our operations). In order to hire reputable foreign expert there are several obstacles: It is not easy to find a person who would know not only nuclear technology training but also do the benchmarking based on our

Topological black holes dressed with a conformally coupled scalar field and electric charge

International Nuclear Information System (INIS)

Martinez, Cristian; Troncoso, Ricardo; Staforelli, Juan Pablo

2006-01-01

Electrically charged solutions for gravity with a conformally coupled scalar field are found in four dimensions in the presence of a cosmological constant. If a quartic self-interaction term for the scalar field is considered, there is a solution describing an asymptotically locally AdS charged black hole dressed with a scalar field that is regular on and outside the event horizon, which is a surface of negative constant curvature. This black hole can have negative mass, which is bounded from below for the extremal case, and its causal structure shows that the solution describes a ''black hole inside a black hole''. The thermodynamics of the nonextremal black hole is analyzed in the grand canonical ensemble. The entropy does not follow the area law, and there is an effective Newton constant which depends on the value of the scalar field at the horizon. If the base manifold is locally flat, the solution has no electric charge, and the scalar field has a vanishing stress-energy tensor so that it dresses a locally AdS spacetime with a nut at the origin. In the case of vanishing self interaction, the solutions also dress locally AdS spacetimes, and if the base manifold is of negative constant curvature a massless electrically charged hairy black hole is obtained. The thermodynamics of this black hole is also analyzed. It is found that the bounds for the black holes parameters in the conformal frame obtained from requiring the entropy to be positive are mapped into the ones that guarantee cosmic censorship in the Einstein frame

Reinforcing Quality Assurance in Romanian Higher Education

Full Text Available Since 1993, the quality assurance system in Romania has gained considerable experience. This experience was recently recognized in 2008 by the ENQA: European Association for Quality Assurance in Higher Education through the admission of ARACIS as a full member of EQAR: the European Quality Assurance Register. The Board of ENQA agreed to grant ARACIS’s full membership of ENQA for five years from 2 June 2009. This article explores the benefits of membership for the Romanian Agency for Quality Assurance in Higher Education – ARACIS, comparing to other regional and global quality assurance agencies networks. The common features and differences between ARACIS and other European agencies are questioned through the frameworks of ENQA and INQAAHE as a case study.

Collapse of a self-gravitating Bose-Einstein condensate with attractive self-interaction

Chavanis, Pierre-Henri

2016-10-01

We study the collapse of a self-gravitating Bose-Einstein condensate with attractive self-interaction. Equilibrium states in which the gravitational attraction and the attraction due to the self-interaction are counterbalanced by the quantum pressure (Heisenberg's uncertainty principle) exist only below a maximum mass Mmax=1.012 ℏ/√{G m |as| } where asMmax the system is expected to collapse and form a black hole. We study the collapse dynamics by making a Gaussian ansatz for the wave function and reducing the problem to the study of the motion of a particle in an effective potential. We find that the collapse time scales as (M /Mmax-1 )-1 /4 for M →Mmax+ and as M-1 /2 for M ≫Mmax. Other analytical results are given above and below the critical point corresponding to a saddle-node bifurcation. We apply our results to QCD axions with mass m =10-4 eV /c2 and scattering length as=-5.8 ×10-53 m for which Mmax=6.5 ×10-14M⊙ and R =3.3 ×10-4R⊙. We confirm our previous claim that bosons with attractive self-interaction, such as QCD axions, may form low mass stars (axion stars or dark matter stars) but cannot form dark matter halos of relevant mass and size. These mini axion stars could be the constituents of dark matter. They can collapse into mini black holes of mass ˜10-14M⊙ in a few hours. In that case, dark matter halos would be made of mini black holes. We also apply our results to ultralight axions with mass m =1.93 ×10-20 eV /c2 and scattering length as=-8.29 ×10-60 fm for which Mmax=0.39 ×1 06M⊙ and R =33 pc . These ultralight axions could cluster into dark matter halos. Axionic dark matter halos with attractive self-interaction can collapse into supermassive black holes of mass ˜1 06M⊙ (similar to those reported at the center of galaxies) in about one million years. We point out the limitations of the Gaussian ansatz to describe the late stages of the collapse dynamics. We also mention the possibility that, instead of forming a black hole

2013-01-01

Breast cancer is the most common cancer diagnosed in females in Sri Lanka and early detection can lead to reduction in morbidity and mortality. To evaluate selected aspects of breast cancer early detection services implemented through well woman clinics (WWCs) in the Gampaha District. The study consisted of two components. A retrospective descriptive arm assessed clinical breast examination (CBE) coverage of target age group women (TGW) of 35-59 years in all the WWCs in Gampaha district over 2003- 2007. A cross sectional descriptive study additionally assessed quality of breast cancer early detection services. The Lot Quality Assurance Sampling (LQAS) technique was used to decide on the lot size and threshold values, which were computed as twenty and six clinics. Checklists were employed in assessing coverage, physical facilities and clinic activities. Client satisfaction on WWC services was assessed among 200 TGW attending 20 WWCs using an interviewer-administered questionnaire. CBE coverage in the Gampaha district increased only from 1.1-2.2% over 2003-2007. With regard to physical facilities, the number of clinics that were rated substandard varied between 7-18 (35- 90%). The items that were lacking included dust bins, notice boards, stationary, furniture and linen, and cleanliness of outside premises and toilets. With regard to clinic activities, punctuality of staff, late commencement of clinics, provision of health education, supervision, CBE and breast self-examination (BSE) were substandard in 7- 20 clinics (35-100%). Client satisfaction for WWC services was 45.2% (IQR: 38.7-54.8%) and only 11% had a score of ≥70%, the cut off set for satisfaction. Breast cancer early detection service coverage in the Gampaha district remained low (2.2%) in 2007, 11 years after commencing WWCs. All 20 clinics were substandard for overall CBE and BSE.

Thermal BEC Black Holes

Full Text Available We review some features of Bose–Einstein condensate (BEC models of black holes obtained by means of the horizon wave function formalism. We consider the Klein–Gordon equation for a toy graviton field coupled to a static matter current in a spherically-symmetric setup. The classical field reproduces the Newtonian potential generated by the matter source, while the corresponding quantum state is given by a coherent superposition of scalar modes with a continuous occupation number. An attractive self-interaction is needed for bound states to form, the case in which one finds that (approximately one mode is allowed, and the system of N bosons can be self-confined in a volume of the size of the Schwarzschild radius. The horizon wave function formalism is then used to show that the radius of such a system corresponds to a proper horizon. The uncertainty in the size of the horizon is related to the typical energy of Hawking modes: it decreases with the increasing of the black hole mass (larger number of gravitons, resulting in agreement with the semiclassical calculations and which does not hold for a single very massive particle. The spectrum of these systems has two components: a discrete ground state of energy m (the bosons forming the black hole and a continuous spectrum with energy ω > m (representing the Hawking radiation and modeled with a Planckian distribution at the expected Hawking temperature. Assuming the main effect of the internal scatterings is the Hawking radiation, the N-particle state can be collectively described by a single-particle wave-function given by a superposition of a total ground state with energy M = Nm and Entropy 2015, 17 6894 a Planckian distribution for E > M at the same Hawking temperature.

Vixen resistin': redefining black womanhood in hip-hop music videos.

Science.gov (United States)

Balaji, Murali

2010-01-01

In recent years, scholarship on Black womanhood has become more closely connected to postmodern discourses on identity and resistance, following in the footsteps of Audre Lorde's claim that identity and sexuality have emancipatory potential. However, in the post-hip-hop era, feminists and media critics have once again brought up the idea of who controls the image. The purpose of this study is to describe possible sites of self-definition by Black women in music videos while accounting for the cultural industries that reproduce and exploit Black women's sexuality. Using textual analysis and the perspective of a noted music video performer, Melyssa Ford, this study articulates the expanse of ambiguity that lies between the images of Black womanhood that bombard consumers of BET and MTV and the selfconceptualization of the women who play those roles.

Qualtity assurance in nuclear technology

International Nuclear Information System (INIS)

Roesler, U.

1977-01-01

The demand for safety in nuclear power plants is rooted in the Atomic Energy Act of the Federal Republic of Germany, under which 'preplanned safety' is a licensing condition. Moreover, the safety of nuclear power plants is outlined in more precise terms in the guidelines of the German Advisory Committee for Reactor Safeguards (Reaktorsicherheitskommission). The usual approach taken in this country, i.e., to establish quality assurance for each specific product, with supplementary quality assurance measures geared to systems requirements being implemented by industry, has proved to work satisfactorily. Product-based quality assurance mainly stems from the classical quality control concept, whereas systems-based quality assurance primarily is to ensure that both manufacturers and systems suppliers take all measures in advance which are needed for the satisfactory processing of an order and to achieve the quality level required. The special features and the advantages of the joint action of manufacturers, systems suppliers and experts, which are characteristic of the German approach, very clearly emerge from a comparison with practices in the United States. In the further refinement of the quality assurance concept as practised in Germany, qhich will have a particularly great impact on costs and schedules because of the manpower requirement involved, it should be carefully weighed where there are exaggerations and unnecessary complications which can no longer be justified by the demand for more safety.

Impression management serves self-preservation as part of self-experience. It is adapted to a given situation as an expression of understanding of the role it plays in striving for success. Impression management and self-presentation mutually influence each other throughout life. Clichés in the traditional self-presentation of men and woman in their gender-specific domain in occupation belong to the past. In employment, contentment as much as discontent are of prime importance for success or failure in the workplace. As role models attract mainly juveniles, they should be held up to critical scrutiny.

The doubling of stellar black hole nuclei

Science.gov (United States)

Kazandjian, Mher V.; Touma, J. R.

2013-04-01

It is strongly believed that Andromeda's double nucleus signals a disc of stars revolving around its central supermassive black hole on eccentric Keplerian orbits with nearly aligned apsides. A self-consistent stellar dynamical origin for such apparently long-lived alignment has so far been lacking, with indications that cluster self-gravity is capable of sustaining such lopsided configurations if and when stimulated by external perturbations. Here, we present results of N-body simulations which show unstable counter-rotating stellar clusters around supermassive black holes saturating into uniformly precessing lopsided nuclei. The double nucleus in our featured experiment decomposes naturally into a thick eccentric disc of apo-apse aligned stars which is embedded in a lighter triaxial cluster. The eccentric disc reproduces key features of Keplerian disc models of Andromeda's double nucleus; the triaxial cluster has a distinctive kinematic signature which is evident in Hubble Space Telescope observations of Andromeda's double nucleus, and has been difficult to reproduce with Keplerian discs alone. Our simulations demonstrate how the combination of an eccentric disc and a triaxial cluster arises naturally when a star cluster accreted over a preexisting and counter-rotating disc of stars drives disc and cluster into a mutually destabilizing dance. Such accretion events are inherent to standard galaxy formation scenarios. They are here shown to double stellar black hole nuclei as they feed them.

This paper presents a self-aligning ink by integrating an inkjet printing technique and heterostructures to fabricate a black matrix with a micrometer-scale tunable thickness. The black matrix is a grid-like structure used in color filters. Traditionally, a black matrix has been fabricated using photolithography techniques, the disadvantages of which are high material consumption, less fabrication flexibility, complex processing procedures, and high chemical pollution. Inkjet printing technology has garnered attention because of its low material costs, high fabrication flexibility, and reduced processing procedures and pollution. In this study, a fabricating process combining an inkjet printing technique with heterostructures to form stripe-arranged and delta-arranged thickness-tunable black matrices has been demonstrated. The deformation and self-aligning process of ink droplet impingement onto gutters are driven by designed heterogeneous surface properties. The minimum track width attained is 10 µm, which is competitive for color filter resolutions for thin-film transistor liquid crystal displays. The developed technology surmounts the bottlenecks of inkjet printing resolution, and saves more than 75% black material than modern photolithography. (paper)

Gravitational properties of monopole spacetimes near the black hole threshold

International Nuclear Information System (INIS)

Lue, Arthur; Weinberg, Erick J.

2000-01-01

Although nonsingular spacetimes and those containing black holes are qualitatively quite different, there are continuous families of configurations that connect the two. In this paper we use self-gravitating monopole solutions as tools for investigating the transition between these two types of spacetimes. We show how causally distinct regions emerge as the black hole limit is achieved, even though the measurements made by an external observer vary continuously. We find that near-critical solutions have a naturally defined entropy, despite the absence of a true horizon, and that this has a clear connection with the Hawking-Bekenstein entropy. We find that certain classes of near-critical solutions display naked black hole behavior, although they are not truly black holes at all. Finally, we present a numerical simulation illustrating how an incident pulse of matter can induce the dynamical collapse of a monopole into an extremal black hole. We discuss the implications of this process for the third law of black hole thermodynamics. (c) 2000 The American Physical Society

The (zeroth-order) energy of a particle in the background of a black hole is given by Carter's integrals. However, exact calculations of a particle's self-energy (first-order corrections) are still beyond our present reach in many situations. In this paper we use Hawking's area theorem in order to derive bounds on the self-energy of a particle in the vicinity of a black hole. Furthermore, we show that self-energy corrections must be taken into account in order to guarantee the validity of Penrose's cosmic censorship conjecture

Measurement quality assurance

International Nuclear Information System (INIS)

Eisenhower, E.H.

1988-01-01

The quality of a radiation protection program can be no better than the quality of the measurements made to support it. In many cases, that quality is unknown and is merely implied on the basis of a calibration of a measuring instrument. If that calibration is inappropriate or is performed improperly, the measurement result will be inaccurate and misleading. Assurance of measurement quality can be achieved if appropriate procedures are followed, including periodic quality control actions that demonstrate adequate performance. Several national measurement quality assurance (MQA) programs are operational or under development in specific areas. They employ secondary standards laboratories that provide a high-quality link between the National Bureau of Standards and measurements made at the field use level. The procedures followed by these secondary laboratories to achieve MQA will be described, as well as plans for similar future programs. A growing general national interest in quality assurance, combined with strong specific motivations for MQA in the area of ionizing radiation, will provide continued demand for appropriate national programs. Such programs must, however, employ procedures that are cost effective and must be developed with participation by all affected parties

A will to youth: the woman's anti-aging elixir.

Science.gov (United States)

Smirnova, Michelle Hannah

2012-10-01

The logic and cultural myths that buttress the cosmeceutical industry construct the older woman as a victim of old age, part of an "at-risk" population who must monitor, treat and prevent any markers of old age. A content and discourse analysis of 124 advertisements from the US More magazine between 1998 and 2008, revealed three major themes working together to produce this civic duty: (1) the inclusion of scientific and medical authorities in order to define the cosmeceutical as a 'drug' curing a disease, (2) descriptions of the similarities (and differences) between the abilities of cosmeceuticals and cosmetic surgery to restore one's youth, and (3) the logic equating youth with beauty, femininity and power and older age with the absence of these qualities. Together these intersecting logics produce the "will to youth"-the imperative of the aging woman to promote her youthful appearance by any and all available means. Further, by using images and references to fantasies and traditional fairytales, cosmeceutical advertisements both promise and normalize expectations of eternal youth of the aging woman.

This definition reflects that the marriage in Indonesia must be between heterosexual couple. However, a question appears as to whether a man or a woman mentioned thereof is included a man and a woman who were, hermaphrodite, intersex, or nowadays known as person with Disorder of Sexual Development (DSD? The case of AH whereby his marriage is cancelled by the Supreme Court in 2014 for he is not considered as a man, is confirming that this question is important to value the capacity of a person to marry. This writing will apply normative research as well as literature research method upon the positive rules and regulations. The decisions of district courts upon the revision or change of gender and its legal basis will be analysed and be the topic of discussion. Comparison will be applied to compare the marriage requirements between Indonesian Law, Singapore Law and Hong Kong Law.

Redefining and expanding quality assurance.

Science.gov (United States)

Robins, J L

1992-12-01

To meet the current standards of excellence necessary for blood establishments, we have learned from industry that a movement toward organization-wide quality assurance/total quality management must be made. Everyone in the organization must accept responsibility for participating in providing the highest quality products and services. Quality must be built into processes and design systems to support these quality processes. Quality assurance has been redefined to include a quality planning function described as the most effective way of designing quality into processes. A formalized quality planning process must be part of quality assurance. Continuous quality improvement has been identified as the strategy every blood establishment must support while striving for error-free processing as the long-term objective. The auditing process has been realigned to support and facilitate this same objective. Implementing organization-wide quality assurance/total quality management is one proven plan for guaranteeing the quality of the 20 million products that are transfused into 4 million patients each year and for moving toward the new order.

The Construction of the Other and the Self in André Gide's Travels in the Congo and Frantz Fanon's Black Skin, White Masks

Directory of Open Access Journals (Sweden)

Raphaël Lambert

2003-06-01

Full Text Available Reportedly, André Gide's Travels in the Congo (1929 had fostered reforms of the colonial policy in French Africa. In Travels , Gide reports cases of economic exploitation, abuses of power, use of terror, torture, and even homicidal raids against recalcitrant villagers and, at least in one case, Gide takes it upon himself to have a man prosecuted. Yet his account, through the lense of post-colonial thinking, betrays reactionary and biased views of Africans. Gide does not object to the colonial system per se , but rather blames its malfunction on both a lack of infrastructures and administrative involvement. In Black Skin, White Masks (1952, Frantz Fanon denounces colonialism, focusing on its dehumanizing effects. If Fanon believes that it is the responsibility of those oppressed to regain their freedom, he is also aware that colonized people have internalized racial stereotypes to the point of self-loathing. Hence Black Skin can be read as a rebuttal to Travels . While Travels , published only twenty years earlier, clings to values of past centuries—supporting France's "civilizing" mission in Africa, Black Skin looks toward the future as it condemns the ideology of colonialism. Both liberals, communist sympathizers and social activists, Gide and Fanon represent the two opposite poles of the colonial issue.

The second purpose is to explore how teachers can use the documents found on the world wide web to teach woman suffrage in their classrooms. Woman suffrage has proved to be a fruitful…

Regulatory viewpoint on nuclear fuel quality assurance

International Nuclear Information System (INIS)

Tripp, L.E.

1976-01-01

Considerations of the importance of fuel quality and performance to nuclear safety, ''as low reasonably achievable'' release of radioactive materials in reactor effluents, and past fuel performance problems demonstrate the need for strong regulatory input, review and inspection of nuclear fuel quality assurance programs at all levels. Such a regulatory program is being applied in the United States of America by the US Nuclear Regulatory Commission. Quality assurance requirements are contained within government regulations. Guidance on acceptable methods of implementing portions of the quality assurance program is contained within Regulatory Guides and other NRC documents. Fuel supplier quality assurance program descriptions are reviewed as a part of the reactor licensing process. Inspections of reactor licensee control of their fuel vendors as well as direct inspections of fuel vendor quality assurance programs are conducted on a regularly scheduled basis. (author)

Objective Explores the hidden vulnerability of individuals with compartmentalized self-concept structures by linking research on self-organization to related models of self functioning. Method Across three studies, college students completed self-descriptive card sorts as a measure of self-concept structure and either the Contingencies of Self-Worth Scale; Likert ratings of perceived authenticity of self-aspects; or a response latency measure of self-esteem accessibility. In all, there were 382 participants (247 females; 77% White, 6% Hispanic, 5% Black, 5% Asian, 4% Native American, and 3% Other). Results Consistent with their unstable self-evaluations, compartmentalized individuals report greater contingencies of self-worth and describe their experience of multiple self-aspects as less authentic than do individuals with integrative self-organization. Compartmentalized individuals also make global self-evaluations more slowly than do integrative individuals. Conclusions Together with previous findings on self-clarity, these results suggest that compartmentalized individuals may experience difficulties in how they know the self, whereas individuals with integrative self-organization may display greater continuity and evaluative consistency across self-aspects, with easier access to evaluative self-knowledge.

In 2000, the Norwegian Radiation Protection Authority (N.R.P.A.) initiated work to develop a national quality assurance programme in radiotherapy. The program was named K.V.I.S.T.: i.e. Norwegian abbreviation of Quality Assurance in Radiotherapy (KValitetSikring STraleterapi). The programme is performed by the multidisciplinary K.V.I.S.T. Group and aims to stimulate collaboration by focussing on clinical, technical and administrative problems that can be addressed and solved on a national level. An important objective is to establish a positive attitude towards quality assurance and better communication between centres and the various professions and professionals involved in radiotherapy, i.e. the oncologists, medical physicists and radiation therapy technologists. Information is also provided to other stake holders such as health authorities, hospital administrators and patients. In 2007 radiotherapy in Norway represent 10 departments and forty accelerators. Since radiotherapy is given high priority in cancer care good quality assurance is required. The member of the K.V.I.S.T.-group are part time at N.R.P.A. and part time in different radiotherapy departments. Professionals with competencies within radiotherapy (R.T.) have permanent positions in a national public entity. The K.V.I.S.T.-group is multidisciplinary. The K.V.I.S.T.-group acts as a coordinating group for all type of national Q.A. projects. The recommendations/guidelines are developed by national consensus. The work is performed by the radiotherapy community it self, thus creating an atmosphere of ownership. (N.C.)

QAM: PROPOSED MODEL FOR QUALITY ASSURANCE IN CBSS

Full Text Available Component-based software engineering (CBSE / Component-Based Development (CBD lays emphasis on decomposition of the engineered systems into functional or logical components with well-defined interfaces used for communication across the components. Component-based software development approach is based on the idea to develop software systems by selecting appropriate off-the-shelf components and then to assemble them with a well-defined software architecture. Because the new software development paradigm is much different from the traditional approach, quality assurance for component-based software development is a new topic in the software engineering research community. Because component-based software systems are developed on an underlying process different from that of the traditional software, their quality assurance model should address both the process of components and the process of the overall system. Quality assurance for component-based software systems during the life cycle is used to analyze the components for achievement of high quality component-based software systems. Although some Quality assurance techniques and component based approach to software engineering have been studied, there is still no clear and well-defined standard or guidelines for component-based software systems. Therefore, identification of the quality assurance characteristics, quality assurance models, quality assurance tools and quality assurance metrics, are under urgent need. As a major contribution in this paper, I have proposed QAM: Quality Assurance Model for component-based software development, which covers component requirement analysis, component development, component certification, component architecture design, integration, testing, and maintenance.

Quality assurance has become an important issue. Many societies are adopting quality assurance programs in order to monitor and improve quality of care. To assess the opinion of gastroenterologists towards quality assurance on the endoscopy department. A survey was sent to all gastroenterologists (n=319) in the Netherlands. It assessed their opinion on a quality assurance program for endoscopy units, including its design, logistics, and content. 200 gastroenterologists (63%) completed the questionnaire. 95% had a positive opinion towards quality assurance and 67% supposed an increase in quality. 28% assumed a negative impact on the time available for patient contact by introducing a quality assurance program and 35% that the capacity would decrease. A negative attitude towards disclosure of results to insurance companies (23%) and media (53%) was reported. Female gastroenterologists were less positive to share the results with other stakeholders (pquality measurements were assessment of complications (97%), standardised reporting (96%), and adequate patient information (95%). Gastroenterologists have a positive attitude towards quality assurance. However, concerns do exist about time investment and disclosure of results to others. Information provision and procedure characteristics were considered the most important aspects of quality assurance. Copyright © 2010 Editrice Gastroenterologica Italiana S.r.l.

Quality assurance in the manufacture of pressure components

Knoedler, D.

1979-01-01

New regulations for nuclear power plants emphasize more quality assurance than it was the case in the past. Quality assurance is a management tool. During erection the quality assurance measures of the manufacturer, the main contractor and the required quality and the reliability of the proof of quality. The qualification of processes, equipment and personnel is a significant measure of quality assurance. The proof for quality assurance to be effective needs not only system-oriented audits, but also product audits aimed at quality characteristics of the product itself. The existing problems of examination techniques not optimized according to latest experience and of the large volume of documetation will persist in case the existing regulations are not adjusted according to the results of relevant studies. Furthermore the effectiveness of quality assurance is too often hampered by vague definitions of the safety objectives. (orig.) [de

Application of software quality assurance methods in validation and maintenance of reactor analysis computer codes

International Nuclear Information System (INIS)

Reznik, L.

1994-01-01

Various computer codes employed at Israel Electricity Company for preliminary reactor design analysis and fuel cycle scoping calculations have been often subject to program source modifications. Although most changes were due to computer or operating system compatibility problems, a number of significant modifications were due to model improvement and enhancements of algorithm efficiency and accuracy. With growing acceptance of software quality assurance requirements and methods, a program of implementing extensive testing of modified software has been adopted within the regular maintenance activities. In this work survey has been performed of various software quality assurance methods of software testing which belong mainly to the two major categories of implementation ('white box') and specification-based ('black box') testing. The results of this survey exhibits a clear preference of specification-based testing. In particular the equivalence class partitioning method and the boundary value method have been selected as especially suitable functional methods for testing reactor analysis codes.A separate study of software quality assurance methods and techniques has been performed in this work objective to establish appropriate pre-test software specification methods. Two methods of software analysis and specification have been selected as the most suitable for this purpose: The method of data flow diagrams has been shown to be particularly valuable for performing the functional/procedural software specification while the entities - relationship diagrams has been approved to be efficient for specifying software data/information domain. Feasibility of these two methods has been analyzed in particular for software uncertainty analysis and overall code accuracy estimation. (author). 14 refs

In the workplace, Black women encounter different job demands than their White counterparts and often experience less control. Demand-control theory offers a framework to examine the challenges Black women face as well as how factors such as coping strategies and social support can moderate levels of well-being. In this study we examined the impact of Black women's social support and coping strategies on job-family role strain, career satisfaction, and life satisfaction. Responses were collected from 188 highly educated Black American women employed in variety of occupations. Results of path modeling found that social support is important to well-being, and that self-help coping can overcome deficient social support's impact on well-being. Exploratory analyses revealed that support from ones' family, church, coworkers, and supervisor each individually related to aspects of well-being, particularly when self-help coping is low.

Black strings, low viscosity fluids, and violation of cosmic censorship.

Lehner, Luis; Pretorius, Frans

We describe the behavior of 5-dimensional black strings, subject to the Gregory-Laflamme instability. Beyond the linear level, the evolving strings exhibit a rich dynamics, where at intermediate stages the horizon can be described as a sequence of 3-dimensional spherical black holes joined by black string segments. These segments are themselves subject to a Gregory-Laflamme instability, resulting in a self-similar cascade, where ever-smaller satellite black holes form connected by ever-thinner string segments. This behavior is akin to satellite formation in low-viscosity fluid streams subject to the Rayleigh-Plateau instability. The simulation results imply that the string segments will reach zero radius in finite asymptotic time, whence the classical space-time terminates in a naked singularity. Since no fine-tuning is required to excite the instability, this constitutes a generic violation of cosmic censorship.

Population aging is a demographic reality for Brazil. Consequently, in the next years it is expected a progressive increase in seeking health care services in the country by women with complaints related to climacterium. Parallel to it, assistance at this part of woman's life has been going through a paradigm shift which has imposed to health professionals a change of attitude in relation to this stage of woman's life. Today it is acknowledged that the climacterium is influenced by biological, psychosocial and cultural factors, whose knowledge is fundamental for planning a more qualified and humanized care. This article proposes a reflection on the paradigm shifts in assistance at climacterium, highlighting important aspects as multidisciplinarity and interdisciplinarity, so as to serve better this portion of population, and provide it with more integrated and individualized care, bringing together knowledge and sensitivity, and always aiming at a better quality of life.
