    Perfect synchronicity in N-player games is a useful theoretical dream, but communication delays are inevitable and may result in asynchronous interactions. Some systems such as financial markets are asynchronous by design, and yet most theoretical models assume perfectly synchronized actions. We propose a general method to transform standard models of adaptive agents into asynchronous systems while preserving their global structure under some conditions. Using the minority game as an example, we find that the phase and fluctuations structure of the standard game subsists even in maximally asynchronous deterministic case, but that it disappears if too much stochasticity is added to the temporal structure of interaction. Allowing for heterogeneous communication speeds and activity patterns gives rise to a new information ecology that we study in details. in here

    In this study, investigation of some anther structures in Sanguisorba minor Scop. subsp. muricata was aimed. Therefore, anthers were squashed by modified glycerine-gelatine method and additionally different histochemical stainings also were tested. The result illustrated that in different parts of anther, such as marginal, connection tissue, starch and protein granules accumulated. Furthermore, during maturation these deposits were detected in pollen grains also. In addition, a very interesting feature, balloon-like structures filled by proteins, were observed in anther cavity. In the light of these findings, their importance on pollen development was discussed.

    In our recent publication on bioactive guided isolation of compounds from Physalis longifolia (Solanaceae) novel anti-proliferative agents withalongolides A (4) and B (5), and their highly cytotoxic analogues, withalongolide A 4,19,27-triacetate (4a) and withalongolide B 4,19-diacetate (5a) were elucidated. In this study, the two lead compounds (4, 5) were re-isolated in gram quantities for the purpose of further analogue preparation and in vivo testing that would continue to probe structure-activity relationships. During this process, two additional withanolides, named withalongolides O (1) and P (2), were elucidated. Their structures were determined by spectroscopic techniques with 1 being subsequently confirmed by X-ray crystallographic analysis. Utilizing a MTS [3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium] viability assay, withalongolide O (1) and its 4,7-diaceatate (1a), both containing the functionalities of Δ(2)-1-oxo- in A ring, a 5β,6β-epoxy in B ring, and a lactone ring in the nine-carbon side chain, exhibited potent cytotoxicity against human head and neck squamous cell carcinoma (JMAR and MDA-1986), melanoma (B16F10 and SKMEL-28), and normal fetal lung fibroblast (MRC-5) cells with IC(50) values in the range between 0.15 and 2.95 µM. In addition, the previously reported α orientation of 7-acetate group in acnistins C and D should be revised to the β orientation on the basis of NMR data comparison.

    Work on structural stigma shows how public policy affects health outcomes for members of devalued groups, including sexual minorities. In the current research, structural stigma is proposed as a moderating variable that strengthens deleterious associations between perceived discrimination and social relationship functioning. Hypotheses were tested in two cross-sectional studies, including both online (N = 214; Study 1) and community (N = 94; Study 2) samples of sexual minority men and women residing throughout the United States. Structural stigma was coded from policy related to sexual minority rights within each state. Confirming hypotheses, support for the moderating role of structural stigma was found via multilevel models across studies. Specifically, associations between perceived discrimination and friendship strain, loneliness (Study 1) and familial strain (Study 2) were increased for those who resided in states with greater levels of structural stigma and attenuated for those who resided in states with lesser levels. In Study 1, these results were robust to state-level covariates (conservatism and religiosity), but conservatism emerged as a significant moderator in lieu of structural stigma in Study 2. Results are discussed in the context of the shifting landscape of public policy related to sexual minority rights within the United States. PMID:26807046

    Stigma operates at multiple levels, including intrapersonal appraisals (e.g., self-stigma), interpersonal events (e.g., hate crimes), and structural conditions (e.g., community norms, institutional policies). Although prior research has indicated that intrapersonal and interpersonal forms of stigma negatively affect the health of the stigmatized, few studies have addressed the health consequences of exposure to structural forms of stigma. To address this gap, we investigated whether structural stigma-operationalized as living in communities with high levels of anti-gay prejudice-increases risk of premature mortality for sexual minorities. We constructed a measure capturing the average level of anti-gay prejudice at the community level, using data from the General Social Survey, which was then prospectively linked to all-cause mortality data via the National Death Index. Sexual minorities living in communities with high levels of anti-gay prejudice experienced a higher hazard of mortality than those living in low-prejudice communities (Hazard Ratio [HR] = 3.03, 95% Confidence Interval [CI] = 1.50, 6.13), controlling for individual and community-level covariates. This result translates into a shorter life expectancy of approximately 12 years (95% C.I.: 4-20 years) for sexual minorities living in high-prejudice communities. Analysis of specific causes of death revealed that suicide, homicide/violence, and cardiovascular diseases were substantially elevated among sexual minorities in high-prejudice communities. Strikingly, there was an 18-year difference in average age of completed suicide between sexual minorities in the high-prejudice (age 37.5) and low-prejudice (age 55.7) communities. These results highlight the importance of examining structural forms of stigma and prejudice as social determinants of health and longevity among minority populations.

  11. Analyses of Lettuce Drop Incidence and Population Structure of Sclerotinia sclerotiorum and S. minor.

    ABSTRACT To understand the geographical distribution of lettuce drop incidence and the structure of Sclerotinia minor and S. sclerotiorum populations, commercial lettuce fields were surveyed in the Salinas, San Joaquin, and Santa Maria Valleys in California. Lettuce drop incidence, pathogen species, and mycelial compatibility groups (MCGs) were determined and analyzed using geostatistic and geographical information system tools. Lettuce drop incidence was lowest in the San Joaquin Valley, and not significantly different between the other two valleys. Semivariogram analysis revealed that lettuce drop incidence was not spatially correlated between different fields in the Salinas Valley, suggesting negligible field-to-field spread or influence of inoculum in one field on other fields. Lettuce drop incidence was significantly lower in fields with a surface drip system than in fields with furrow or sprinkler irrigation systems, suggesting that the surface drip system can be a potential management measure for reducing lettuce drop. In the San Joaquin Valley, S. sclerotiorum was the prevalent species, causing drop in 63.5% of the fields, whereas S. minor also was identified in 25.4% of the fields. In contrast, in the Salinas Valley, S. minor was the dominant species (76.1%) whereas S sclerotiorum only observed in only 13.6% fields, in which only a few plants were infected by S. sclerotiorum. In the Santa Maria Valley, both species frequently were identified, with S. minor being slightly more common. Although many MCGs were identified in S. minor, most of them consisted of only one or two isolates. In all, approximately 91.4% of the isolates belonged to four MCGs. Among them, MCG-1 was the most prevalent group in all three valleys, accounting for 49.8% of total isolates. It was distributed all over the surveyed areas, whereas other MCGs were distributed more or less locally. Populations of S. sclerotiorum exhibited greater diversity, with 89 isolates collected from the

    The structural complexity and microheterogeneity of the glycosaminoglycans heparin and heparan sulfate make their characterization a daunting task. The methodology described herein utilizes a combination of enzymatic digestion, size-exclusion chromatography, strong anion-exchange HPLC, reverse-phase ion-pair ultrahigh performance liquid chromatography-mass spectrometry, and microcoil NMR for the efficient sequencing of heparin-derived tetrasaccharides. The high mass sensitivity of microcoil NMR makes this technique well suited for the characterization of mass-limited samples removing a bottleneck in the analysis workflow and permitting structural characterization of minor components isolated from a heparin enzymatic digestion. Complete characterization of one tetrasulfonated, five pentasulfonated isomers and two hexasulfonated tetrasaccharide sequences is described. To our knowledge, two of the identified minor tetrasaccharides are unique, and have not been previously reported: IdoA(2S)-GlcNS(6S)-IdoA(2S)-GlcNS(6S) and ΔUA(2S)-GlcNS(6S)-IdoA-GlcNS(6S).

    Factors responsible for spatial structuring of population genetic variation are varied, and in many instances there may be no obvious explanations for genetic structuring observed, or those invoked may reflect spurious correlations. A study of little penguins (Eudyptula minor) in southeast Australia documented low spatial structuring of genetic variation with the exception of colonies at the western limit of sampling, and this distinction was attributed to an intervening oceanographic feature (Bonney Upwelling), differences in breeding phenology, or sea level change. Here, we conducted sampling across the entire Australian range, employing additional markers (12 microsatellites and mitochondrial DNA, 697 individuals, 17 colonies). The zone of elevated genetic structuring previously observed actually represents the eastern half of a genetic cline, within which structuring exists over much shorter spatial scales than elsewhere. Colonies separated by as little as 27 km in the zone are genetically distinguishable, while outside the zone, homogeneity cannot be rejected at scales of up to 1400 km. Given a lack of additional physical or environmental barriers to gene flow, the zone of elevated genetic structuring may reflect secondary contact of lineages (with or without selection against interbreeding), or recent colonization and expansion from this region. This study highlights the importance of sampling scale to reveal the cause of genetic structuring.

    Many viruses regulate translation of polycistronic mRNA using a -1 ribosomal frameshift induced by an RNA pseudoknot. A pseudoknot has two stems that form a quasi-continuous helix and two connecting loops. A 1.6 A crystal structure of the beet western yellow virus (BWYV) pseudoknot reveals rotation and a bend at the junction of the two stems. A loop base is inserted in the major groove of one stem with quadruple-base interactions. The second loop forms a new minor-groove triplex motif with the other stem, involving 2'-OH and triple-base interactions, as well as sodium ion coordination. Overall, the number of hydrogen bonds stabilizing the tertiary interactions exceeds the number involved in Watson-Crick base pairs. This structure will aid mechanistic analyses of ribosomal frameshifting.

    The recognition of specific DNA-binding sites by transcription factors is a critical yet poorly understood step in the control of gene expression. Members of the Hox family of transcription factors bind DNA by making nearly identical major groove contacts via the recognition helices of their homeodomains. In vivo specificity, however, often depends on extended and unstructured regions that link Hox homeodomains to a DNA-bound cofactor, Extradenticle (Exd). Using a combination of structure determination, computational analysis, and in vitro and in vivo assays, we show that Hox proteins recognize specific Hox-Exd binding sites via residues located in these extended regions that insert into the minor groove but only when presented with the correct DNA sequence. Our results suggest that these residues, which are conserved in a paralog-specific manner, confer specificity by recognizing a sequence-dependent DNA structure instead of directly reading a specific DNA sequence.

  16. Factors influencing subcellular localization of the human papillomavirus L2 minor structural protein

    Two structural proteins form the capsids of papillomaviruses. The major structural protein L1 is the structural determinant of the capsids and is present in 360 copies arranged in 72 pentamers. The minor structural protein L2 is estimated to be present in twelve copies per capsid. Possible roles for L2 in interaction with cell surface receptors and in virion uptake have been suggested. As previously reported, L2 localizes in subnuclear domains identified as nuclear domain 10 (ND10). As it was demonstrated that L2 is able to recruit viral and cellular proteins to ND10, a possible role for L2 as a mediator in viral assembly has been proposed. In this study, we determined factors influencing the localization of L2 at ND10. Under conditions of moderate L2 expression level and in the absence of heterologous viral components, we observed that, in contrast to previous reports, L2 is mainly distributed homogeneously throughout the nucleus. L2, however, is recruited to ND10 at a higher expression level or in the presence of viral components derived from vaccinia virus or from Semliki Forest virus. We observed that translocation of L2 to ND10 is not a concentration-dependent accumulation but rather seems to be triggered by yet unidentified cellular factors. In contrast to HPV 11 and 16 L2, the HPV 18 L2 protein seems to require L1 for efficient nuclear accumulation.

    The authors investigated theoretically core-hole effects on X-ray absorption near-edge structures (XANES) of Np and Am LIII in neptunium dioxide (NpO2) and americium dioxide (AmO2) with CaF2-type crystal lattices using the all-electron full-potential linearized augmented plane-wave (FP-LAPW) method. The peak creation mechanism of XANES was shown by examining the electronic structures of these oxides, which indicated that core-hole screening was more marked for AmO2 than for NpO2 because of the difference in the charge transfer between these oxides. Furthermore, the results of charge density analysis suggested that the white line was assigned to the quasi-bound state composed of the localized Np d or Am d components and O components, and that the tail structure was created as a result of delocalized standing waves between the Np or Am atoms.

    The role of microhydration in structural adjustments of the AT-tract in B-DNA was studied at the B97-D/def2-SV(P) level. The (dA:dT)5 complexes with 10 water molecules in minor and 15 water molecules in major grooves were studied. The obtained network of hydrogen bonds revealed the dependence between the groove width and the types of water patterns. In the minor groove, the following patterns were observed: interstrand one-water bridges similar to that of the Dickerson "water spine" and interstrand two-water bridges. The network of structural waters in the major groove is more diverse than that in the minor groove, which agrees with crystallographic data. As the major groove is wider, it is enriched by water molecules forming two- and three-water bridges. Results suggest the nucleobase-water interactions in both grooves prevent AT-tract twisting and its "collapse" along the minor groove. Whereby, a helix structure with narrow minor and wide major grooves is formed. The structural waters affect the polynucleotide conformation so that it becomes similar to poly(dA)·poly(dT) in fibers and acquires features of the A-tracts in DNA in solution. We suggest that formation of specific water patterns in both grooves is the factor responsible for stabilization of A-tracts with a narrowed minor groove, leading in turn to their strong intrinsic bending in DNA.

    Submillimeter observations obtained with the Atacama Large Millimeter Array (ALMA) allowed to monitoring the temporal evolution of temperature, sulfur species and water in the upper atmosphere of Venus. We observed the upper atmosphere of Venus with ALMA on November 14, 15, 26 and 27, 2011 during the first ALMA Early Science observation cycle. These observations targeted CO, SO, HDO and SO2 transitions around 345 GHz during four sequences of 30 minutes each. The disk of Venus was about 11" with an illumination factor of 90%, so that mostly the dayside of the planet was mapped.Thanks to the imaging capabilities of ALMA, we could obtain instantaneous maps of temperature, SO and HDO for the four days of observations. Assuming a nominal dayside CO abundance profile adapted from Clancy et al. 2012, we retrieved vertical temperature profiles between 60-100 km of altitude over the entire disk as a function of latitude and local time for the four days of observation. Temperature profiles were later used to derive the abundances of minor species (SO and HDO) in each pixel of the disk in order to study their spatial and temporal variability. Moreover, we plan to analyze the SO2 disk-averaged spectra to study its temporal variability.Temperature profiles show at all latitudes and local times a similar behavior with a constant decrease of temperature up to an altitude of about 80-100 km, depending on the local time, followed by a constant increase of temperature. Up to about 90 km temperatures increase from the morning side towards the evening terminator, this trend is inverted above 90 km. The thermal structure does not show strong temporal variations from one day to another. An exception is the thermal structure of the November 27: compared to the first day of observation, temperatures change of more than 15 K.SO exhibits a strong spatial and temporal variability with a mixing ratio ranging from 0 to 15 ppb. It presents also a clear cutoff around 89 km. HDO is detected

    Summary BK polyomavirus is the causative agent of several diseases in transplant patients and the immunosuppressed. In order to better understand the structure and life cycle of BK, we produced infectious virions and VP1-only virus-like particles in cell culture, and determined their three-dimensional structures using cryo-electron microscopy (EM) and single-particle image processing. The resulting 7.6-Å resolution structure of BK and 9.1-Å resolution of the virus-like particles are the highest-resolution cryo-EM structures of any polyomavirus. These structures confirm that the architecture of the major structural protein components of these human polyomaviruses are similar to previous structures from other hosts, but give new insight into the location and role of the enigmatic minor structural proteins, VP2 and VP3. We also observe two shells of electron density, which we attribute to a structurally ordered part of the viral genome, and discrete contacts between this density and both VP1 and the minor capsid proteins.

  6. Similarities in the structural organization of major and minor ampullate spider silk.

    2009-05-19

    Minor and major ampullate spider silks are studied under varying mechanical stress by static and time-resolved FT-IR spectroscopy. This enables one to trace the external mechanical excitation on a microscopic level and to determine for the different moieties the time dependence of the molecular order parameters and corresponding band shifts. It is concluded that the hierarchical nanostructure of both types of silk is similar, being composed of highly oriented nanocrystals, which are interconnected by amorphous chains that obey the worm-like chain model and have a Gaussian distribution of pre-strain. By that it is possible to describe the mechanical properties of both silks by two adjustable parameters only, the center and width of the distribution. For major ampullate silk, the observed variability is small in pronounced contrast to the findings for minor ampullate.

    Objective To propose a theoretical model and clinical approach to sexual minority patients who consult mental health professionalsMethods Clinicians at the McGill University Sexual Identity Center (MUSIC) who have been treating patients from various sexual minorities for more than 15 years present useful theoretical constructs of gender and sexuality as well as guidelines for the evaluation and treatment of patients consulting for discomfort or confusion surrounding their sexual orientation, their gender identity or both, based on both the current literature and their clinical experience.Results The notions of non-binary construction of gender, of social determinism of gender roles and expression, and of gender creativity are presented. Sexual orientation is divided into four most commonly used dimensions (emotional attraction, physical attraction, behaviour and identity); the fluidity of these and their potential non-concordance are described. The fact that attraction to one gender is independent of attraction to another gender is highlighted. An attitude of openness to all forms of gender expression and sexual orientation constellations is encouraged to allow the patient free exploration of the several facets of their sexuality.Various domains to explore in evaluating sexual orientation and gender as well as therapeutic avenues are proposed. Areas to enquire about include: mental, physical and social experiences of gender, eroticism and sexual fantasies towards all genders, emotional attraction towards them, sexual and romantic experiences, comfort and certainty about one's identity and about disclosing it.Psychoeducation can be used to teach about sexual diversity and to assess the risks and benefits of coming out to self, family, friends, co-workers or strangers. Cognitive strategies can be undertaken to debunk homophobic and transphobic myths which may fuel poor self-esteem. Psychodynamic approaches can be used to heal the narcissistic wounds of homophobia

    The solution structure of a complex between a truncated form of HMG-I(Y), consisting of the second and third DNA binding domains (residues 51-90), and a DNA dodecamer containing the PRDII site of the interferon-beta promoter has been solved by multidimensional nuclear magnetic resonance spectroscopy. The stoichiometry of the complex is one molecule of HMG-I(Y) to two molecules of DNA. The structure reveals a new architectural minor groove binding motif which stabilizes B-DNA, thereby facilitating the binding of other transcription factors in the opposing major groove. The interactions involve a central Arg-Gly-Arg motif together with two other modules that participate in extensive hydrophobic and polar contracts. The absence of one of these modules in the third DNA binding domain accounts for its-100 fold reduced affinity relative to the second one.

    Young children's executive function (EF) is increasingly recognized as an important construct associated with development in cognitive and socioemotional domains. To date, however, few studies have examined EF in populations of language-minority children. In this study, 241 Spanish-speaking language-minority preschoolers who ranged in age from 38 to 69 months (M=54.23 months, SD=6.17) completed three tasks designed to measure inhibitory control (IC) and four tasks designed to measure working memory (WM). Children completed assessments of their vocabulary skills, early literacy skills, and behavioral self-regulation in both English and Spanish, and their classroom teachers completed three behavior rating measures. Children were classified as more proficient in English or Spanish based on their scores on the vocabulary measures, and all IC and WM measures were administered in the children's more proficient language. Results of confirmatory factor analyses supported a two-factor model of EF for both groups of children as well as strong measurement and structural invariance across groups. Children's EF was substantially related to the language, early literacy, and behavioral self-regulation measures as well as teacher ratings of inattention and hyperactivity/impulsivity. For children with more proficient English, EF was associated with skills in both English and Spanish; however, for children with more proficient Spanish, EF was associated primarily with skills in Spanish. These results provide evidence of strong correspondence for EF measured in Spanish-speaking language-minority preschoolers and monolingual preschoolers, and they identify a potential key factor that can enhance understanding of development in this population of children.

    Mcl-1 is an antiapoptotic Bcl-2-family protein that protects cells against death. Structures of Mcl-1, and of other anti-apoptotic Bcl-2 proteins, reveal a surface groove into which the {alpha}-helical BH3 regions of certain proapoptotic proteins can bind. Despite high overall structural conservation, differences in this groove afford binding specificity that is important for the mechanism of Bcl-2 family function. We report the crystal structure of human Mcl-1 bound to a BH3 peptide derived from human Bim and the structures for three complexes that accommodate large physicochemical changes at conserved Bim sites. The mutations had surprisingly modest effects on complex stability, and the structures show that Mcl-1 can undergo small changes to accommodate the mutant ligands. For example, a shift in a leucine side chain fills a hole left by an isoleucine-to-alanine mutation at the first hydrophobic buried position of Bim BH3. Larger changes are also observed, with shifting of helix {alpha}3 accommodating an isoleucine-to-tyrosine mutation at this same position. We surveyed the variation in available Mcl-1 and Bcl-x{sub L} structures and observed moderate flexibility that is likely critical for facilitating interactions of diverse BH3-only proteins with Mcl-1. With the antiapoptotic Bcl-2 family members attracting significant attention as therapeutic targets, these structures contribute to our growing understanding of how specificity is achieved and can help to guide the design of novel inhibitors that target Mcl-1.

  13. Structure of the Minor Pseudopilin EpsH From the Type 2 Secretion System of Vibrio Cholerae

    Many Gram-negative bacteria use the multi-protein type II secretion system (T2SS) to selectively translocate virulence factors from the periplasmic space into the extracellular environment. In Vibrio cholerae the T2SS is called the extracellular protein secretion (Eps) system, which translocates cholera toxin and several enzymes in their folded state across the outer membrane. Five proteins of the T2SS, the pseudopilins, are thought to assemble into a pseudopilus, which may control the outer membrane pore EpsD, and participate in the active export of proteins in a 'piston-like' manner. We report here the 2.0 {angstrom} resolution crystal structure of an N-terminally truncated variant of EpsH, a minor pseudopilin from Vibrio cholerae. While EpsH maintains an N-terminal {alpha}-helix and C-terminal {beta}-sheet consistent with the type 4a pilin fold, structural comparisons reveal major differences between the minor pseudopilin EpsH and the major pseudopilin GspG from Klebsiella oxytoca: EpsH contains a large {beta}-sheet in the variable domain, where GspG contains an {alpha}-helix. Most importantly, EpsH contains at its surface a hydrophobic crevice between its variable and conserved {beta}-sheets, wherein a majority of the conserved residues within the EpsH family are clustered. In a tentative model of a T2SS pseudopilus with EpsH at its tip, the conserved crevice faces away from the helix axis. This conserved surface region may be critical for interacting with other proteins from the T2SS machinery.

    An investigation of the strong-acid characteristics (pKa 3.0 or less) of fulvic acid from the Suwannee River, Georgia, was conducted. Quantitative determinations were made for amino acid and sulfur-containing acid structures, oxalate half-ester structures, malonic acid structures, keto acid structures, and aromatic carboxyl-group structures. These determinations were made by using a variety of spectrometric (13C-nuclear magnetic resonance, infrared, and ultraviolet spectrometry) and titrimetric characterizations on fulvic acid or fulvic acid samples that were chemically derivatized to indicate certain functional groups. Only keto acid and aromatic carboxyl-group structures contributed significantly to the strong-acid characteristics of the fulvic acid; these structures accounted for 43% of the strong-acid acidity. The remaining 57% of the strong acids are aliphatic carboxyl groups in unusual and/or complex configurations for which limited model compound data are available.

  16. Social disintegration and the spread of AIDS--II. Meltdown of sociogeographic structure in urban minority neighborhoods.

    Wallace, R

    1993-10-01

    An elementary model of sociogeographic network structure in an urban minority community suggests externally applied stress, particularly that which triggers frequent individual or family moves of increasing distance, may cause a sudden 'phase change' resulting in disconnection of previously integrated subgroups from the community. Such 'community meltdown' would seriously disrupt mechanisms for social control, economic opportunity and socialization of youth, while intensifying substance abuse and indiscriminate and frequent sexual activity, particularly among the very young. 'Phase change' of this nature would seem to preclude success of programs to control spread of HIV infection, particularly in heterosexual populations. The possibility is explored that programs of 'community recrystalization' in disintegrated urban area might likewise need to exceed some threshold of investment and organizing activity before becoming effective. However, if supported to levels above threshold, this work implies such programs might have very great impact in a very short time. The possibility of interaction between behavioral pathologies resulting from the initial meltdown and further consequent deterioration in sociogeographic network structure leads to speculation that the threshold for recrystalization may become significantly and progressively greater than for meltdown. Implications of these matters for diffusion of HIV into the general population are discussed.

    Synthetic routes to alkyl and aryl substituted dithiophosphinate salts that contain non-coordinating PPh{sub 4}{sup 1+} counter cations are reported. In general, these compounds can be prepared via a multi-step procedure that starts with reacting secondary phosphines, i.e. HPR{sub 2}, with two equivalents elemental S. This transformation proceeds in two steps - first oxidation of the phosphine and second insertion of S into the H-P bond - and has been used to synthesize a series of dithiophoshinic acids, which were fully characterized, namely HS{sub 2}P(p-CF{sub 3}C{sub 6}H{sub 4}){sub 2}, HS{sub 2}P(m-CF{sub 3}C{sub 6}H{sub 4}){sub 2}, HS{sub 2}P(o-MeC{sub 6}H{sub 4}){sub 2}, and HS{sub 2}P(o-MeOC{sub 6}H{sub 4}){sub 2}. Although the insertion step was found to be much slower than the oxidation reaction, the formation of (NH{sub 4})S{sub 2}PR{sub 2} from HPSR{sub 2} occurs almost instantaneous upon addition of NH{sub 4}OH. Subsequent cation exchange reactions proceed readily with PPh{sub 4}Cl in water, under air, and at ambient conditions to provide analytically pure samples of [PPh{sub 4}][S{sub 2}PR{sub 2}] (R = p-CF{sub 3}C{sub 6}H{sub 4}, m-CF{sub 3}C{sub 6}H{sub 4}, o-CF{sub 3}C{sub 6}H{sub 4}, o-MeC{sub 6}H{sub 4}, o-MeOC{sub 6}H{sub 4}, Ph, and Me, 1b-7b, respectively), which were characterized by elemental analysis, multinuclear NMR, and IR spectroscopy. In addition the S{sub 2}PMe{sub 2}{sup 1-}, S{sub 2}PPh{sub 2}{sup 1-}, and dithiophosphinates with ortho-substituted arene rings were characterized by X-ray crystallography. Structural analysis show that, as opposed to the acids which have short P=S double bonds and long P-SH single bonds, the metric parameters for the S atoms in S{sub 2}PR{sub 2}{sup 1-} are equivalent. In addition, the presence of large non-coordinating PPh{sub 4}{sup 1+} cations guard against intermolecular P-S {hor_ellipsis} X interactions and insure that the P-S bond is isolated. Overall, this synthetic procedure provides high

    Synchrotron X-ray micro-diffraction experiments were carried out on Nephila clavipes (NC) and Argiope aurantia (AA) major (MA) and minor ampullate (MiA) fibers that make up dragline spider silk. The diffraction patterns show a semi-crystalline structure with {beta}-poly(L-alanine) nanocrystallites embedded in a partially oriented amorphous matrix. A superlattice reflection 'S' diffraction ring is observed, which corresponds to a crystalline component larger in size and is poorly oriented, when compared to the {beta}-poly(L-alanine) nanocrystallites that are commonly observed in dragline spider silks. Crystallite size, crystallinity and orientation about the fiber axis have been determined from the wide-angle X-ray diffraction (WAXD) patterns. In both NC and AA, the MiA silks are found to be more highly crystalline, when compared with the corresponding MA silks. Detailed analysis on the amorphous matrix shows considerable differences in the degree of order of the oriented amorphous component between the different silks studied and may play a crucial role in determining the mechanical properties of the silks.

    Complex molecular shapes of ribosomal RNA molecules are stabilized by recurrent types of tertiary interactions involving highly specific and conserved non-Watson-Crick base pairs, triplets, and quartets. We analyzed the intrinsic structure and stability of the P-motif and the four basic types of A-minor interactions (types I, II, III, and 0), which represent the most prominent RNA tertiary interaction patterns refined in the course of evolution. In the studied interactions, the electron correlation component of the stabilization usually exceeds the Hartree-Fock (HF) term, leading to a strikingly different balance of forces as compared to standard base pairing stabilized primarily by the HF term. In other words, the A-minor and P-interactions are considerably more influenced by the dispersion energy as compared to canonical base pairs, which makes them particularly suitable to zip the folded RNA structures that are substantially hydrated even in their interior. Continuum solvent COSMO calculations confirm that the stability of the canonical GC base pair is affected (reduced) by the continuum solvent screening considerably more than the stability of the A-minor interaction. Among the studied systems, the strong A-minor II and weak A-minor III interactions require water molecules to stabilize the experimental geometry. Gas-phase optimization of the canonical A-minor II A/CG triplet without water results in a geometry that is clearly inconsistent with the RNA structure. The gas-phase structure of the P-interaction and the most stable A-minor I interaction nicely agrees with the geometries occurring in the ribosome. A-minor I can also adopt an alternative water-mediated substate rather often observed in X-ray and molecular dynamics studies. The A-minor I water bridge, however, does not appear to stabilize the tertiary contact, and its role is to provide structural flexibility to this binding pattern within the context of the RNA structure. Interestingly, the insertion

    The anti-MRSA antibiotic, WAP-8294A, was isolated from the fermentation broth of Lysobacter sp. The major component, WAP-8294A2, is composed of 1 mol of Gly, L-Leu, L-Glu, D-Asn, D-Trp, D-threo-β-hydroxyasparagine, N-Me-D-Phe and N-Me-L-Val, and 2 mol of L-Ser, D-Orn and D-3-hydroxy-7-Me-octanoic acid. The structure of the WAP-8294A2 was mainly determined as a cyclic depsipeptide by 2D NMR experiments. However, it was difficult to use the NMR experiment to determine the minor components, A1, A4 and Ax13, isolated in small amounts. In the present study, ESI MS/MS was applied to the structure elucidation of these minor components. The structures of these minor components were determined on the basis of the fragmentation pattern of the product ions of WAP-8294A2 in the ESI MS/MS. As a result, it was confirmed that A1 and A4 had the same amino acid sequence as A2, while A1 and A4 had the 3-OH-octanoic acid and 3-OH-8-Me-nonanoic acid, respectively, in the place of the 3-OH-7-Me-octanoic acid in A2. In the structure of Ax13, it was found that Gly of A2 was changed to β-Ala of Ax13.

    Avian polyomavirus (APV) causes a fatal, multi-organ disease among several bird species. Using cryogenic electron microscopy and other biochemical techniques, we investigated the structure of APV and compared it to that of mammalian polyomaviruses, particularly JC polyomavirus and simian virus 40. The structure of the pentameric major capsid protein (VP1) is mostly conserved; however, APV VP1 has a unique, truncated C-terminus that eliminates an intercapsomere-connecting {beta}-hairpin observed in other polyomaviruses. We postulate that the terminal {beta}-hairpin locks other polyomavirus capsids in a stable conformation and that absence of the hairpin leads to the observed capsid size variation in APV. Plug-like density features were observed at the base of the VP1 pentamers, consistent with the known location of minor capsid proteins VP2 and VP3. However, the plug density is more prominent in APV and may include VP4, a minor capsid protein unique to bird polyomaviruses.

    The solution structure of the complex between 4', 6-diamidino-2-phenylindole (DAPI) and DNA oligomer [d(GCGATTCGC)]2, containing a central T.T mismatch, has been characterized by combined use of proton one- and two-dimensional NMR spectroscopy, molecular mechanics and molecular dynamics computations including relaxation matrix refinement. The results show that the DAPI molecule binds in the minor groove of the central region 5'-ATT-3' of the DNA oligomer, which predominantly adopts a duplex structure with a global right-handed B-like conformation. In the final models of the complex, the DAPI molecule is located nearly isohelical with its NH indole proton oriented towards the DNA helix axis and forming a bifurcated hydrogen bond with the carbonyl O2 groups of a mismatched T5 and the T6 residue of the opposite strand. Mismatched thymines adopt a wobble base pair conformation and are found stacked between the flanking base pairs, inducing only minor local conformational changes in global duplex structure. In addition, no other binding mechanisms were observed, showing that minor groove binding of DAPI to the mismatch-containing site is favoured in comparison with any other previously reported interaction with G.C sequences.

    Type IV pili are extracellular polymers of the major pilin subunit. These subunits are held together in the pilus filament by hydrophobic interactions among their N-terminal α-helices, which also anchor the pilin subunits in the inner membrane prior to pilus assembly. Type IV pilus assembly involves a conserved group of proteins that span the envelope of Gram-negative bacteria. Among these is a set of minor pilins, so named because they share their hydrophobic N-terminal polymerization/membrane anchor segment with the major pilins but are much less abundant. Minor pilins influence pilus assembly and retraction, but their precise functions are not well defined. The Type IV pilus systems of enterotoxigenic Escherichia coli and Vibrio cholerae are among the simplest of Type IV pilus systems and possess only a single minor pilin. Here we show that the enterotoxigenic E. coli minor pilins CofB and LngB are required for assembly of their respective Type IV pili, CFA/III and Longus. Low levels of the minor pilins are optimal for pilus assembly, and CofB can be detected in the pilus fraction. We solved the 2.0 Å crystal structure of N-terminally truncated CofB, revealing a pilin-like protein with an extended C-terminal region composed of two discrete domains connected by flexible linkers. The C-terminal region is required for CofB to initiate pilus assembly. We propose a model for CofB-initiated pilus assembly with implications for understanding filament growth in more complex Type IV pilus systems as well as the related Type II secretion system.

    We developed the first Vietnamese Internalized Homophobia (IH) scale for use with Vietnamese sexual minority women (SMW). Drawing from existing IH scales in the international literature and based on prior qualitative research about SMW in the Viet Nam context, the scale covers two domains: self-stigma (negative attitudes toward oneself as a sexual minority person) and sexual prejudice (negative attitudes toward homosexuality/same-sex relations in general). Scale items, including items borrowed from existing scales and items based on local expressions, were reviewed and confirmed by members of the target population. Quantitative evaluation used data from an anonymous web-based survey of Vietnamese SMW, including those who identified as lesbian (n = 1187), or as bisexual (n = 641) and those who were unsure about their sexual identity (n = 353). The scale was found to consist of two highly correlated factors reflecting self-stigma (not normal/wholesome and self-reproach and wishing away same-sex sexuality) and one factor reflecting sexual prejudice, and to have excellent internal consistency. Construct validity was evidenced by subscale associations with a wide range of hypothesized correlates, including perceived sexual stigma, outness, social support, connection to other SMW, relationship quality, psychological well-being, anticipation of heterosexual marriage, and endorsement of same-sex marriage legalization. Self-stigma was more strongly associated with psychosocial correlates, and sexual prejudice was more associated with endorsement of legal same-sex marriage. The variations in these associations across the hypothesized correlates and across sexual identity groups were consistent with the minority stress model and the IH literature, and exhibited context-specific features, which are discussed.

    Type IV pili (Tfp) are widespread filamentous bacterial organelles that mediate multiple virulence-related phenotypes. They are composed mainly of pilin subunits, which are processed before filament assembly by dedicated prepilin peptidases. Other proteins processed by these peptidases, whose molecular nature and mode of action remain enigmatic, play critical roles in Tfp biology. We have performed a detailed structure/function analysis of one such protein, PilX from Neisseria meningitidis, which is crucial for formation of bacterial aggregates and adhesion to human cells. The x-ray crystal structure of PilX reveals the α/β roll fold shared by all pilins, and we show that this protein colocalizes with Tfp. These observations suggest that PilX is a minor, or low abundance, pilin that assembles within the filaments in a similar way to pilin. Deletion of a PilX distinctive structural element, which is predicted to be exposed on the filament surface, abolishes aggregation and adhesion. Our results support a model in which surface-exposed motifs in PilX subunits stabilize bacterial aggregates against the disruptive force of pilus retraction and illustrate how a minor pilus component can enhance the functional properties of pili of rather simple composition and structure.

    Bleomycins constitute a widely studied class of complex DNA cleaving natural products that are used to treat various cancers. Since their first isolation, the bleomycins have provided a paradigm for the development and discovery of additional DNA-cleaving chemotherapeutic agents. The bleomycins consist of a disaccharide-modified metal-binding domain connected to a bithiazole/C-terminal tail via a methylvalerate-Thr linker and induce DNA damage after oxygen activation through site-selective cleavage of duplex DNA at 5'-GT/C sites. Here, we present crystal structures of two different 5'-GT containing oligonucleotides in both the presence and absence of bound Co(III){center_dot}bleomycin B2. Several findings from our studies impact the current view of bleomycin binding to DNA. First, we report that the bithiazole intercalates in two distinct modes and can do so independently of well ordered minor groove binding of the metal binding/disaccharide domains. Second, the Co(III)-coordinating equatorial ligands in our structure include the imidazole, histidine amide, pyrimidine N1, and the secondary amine of the {beta} aminoalanine, whereas the primary amine acts as an axial ligand. Third, minor groove binding of Co(III){center_dot}bleomycin involves direct hydrogen bonding interactions of the metal binding domain and disaccharide with the DNA. Finally, modeling of a hydroperoxide ligand coordinated to Co(III) suggests that it is ideally positioned for initiation of C4'-H abstraction.

  12. Synthesis and structure of Ce1-xEuxPO4 solid solutions for minor actinides immobilization

    Ce1-xEuxPO4 (x = 0-1) solid solutions were synthesized by the solid state reaction process using europium (Eu) as the surrogate for trivalent minor actinide americium (Am). The effects of calcination temperature, holding time and Eu content on the crystalline phase, microstructure and morphology of Ce1-xEuxPO4 (x = 0-1) were investigated. The monazite-type EuPO4 and CePO4 coexisted after being calcined at 1000 °C for 4 h, suggesting the CePO4 and EuPO4 phases would form initially separately. Pure and single-phase monazite-type Ce1-xEuxPO4 (x = 0-1) powders were obtained at 1300 °C for 4 h. The results of the XRD patterns Rietveld refinement and μ-Raman analysis confirmed the formation of a Ce1-xEuxPO4 (x = 0-1) continuous solid solution. The grain size of Ce0.5Eu0.5PO4 increased obviously as the holding time extended. The Ce, Eu, P and O elements were almost distributed homogeneously in the Ce0.5Eu0.5PO4 solid solution.

  13. Population clustering and clonal structure evidence the relict state of Ulmus minor Mill. in the Balearic Islands

    Field elm (Ulmus minor) is a riparian tree that grows in rare, small populations scattered along temporary watercourses in the Balearic Islands, nowadays mostly covered with Mediterranean vegetation. Agriculture and farming on the fertile land along the periodically flooded plains have reduced the elm populations to sparse tree lines along the creek beds. The presence of field elm in this very anthropic landscape has led some authors to consider it as an introduced species in the Balearics. However, pollen data suggest these elms may be the remains of larger populations experiencing continuous population shrinkage during the Holocene, and hence be native to the isles. In this paper, we apply genetic markers to assess whether field elm is or is not indigenous to the Balearic Islands. We compare the genetic variation in nine nuclear microsatellites of six Balearic populations (three in each of the largest islands, Majorca and Minorca) with that of three natural Iberian populations located in two regions, one geologically (Baetic mountains, SE Iberia) and another historically (Catalonia, NE Iberia) related to the islands. Principal coordinates analysis and Bayesian clustering methods reveal a strong genetic differentiation of the Balearic populations from the Iberian ones, and even among islands, which support their native origin. Genotypic variation in the islands is very low and clonal reproduction is very high compared with the mainland, as it is frequently observed in populations of clonal species where sexual reproduction is limited. We discuss the practical implications of these findings for the conservation of elm genetic resources of these findings. PMID:24619184

    The type II secretion complex exports folded proteins from the periplasm to the extracellular milieu. It is used by the pathogenic bacterium Vibrio cholerae to export several proteins, including its major virulence factor, cholera toxin. The pseudopilus is an essential component of the type II secretion system and likely acts as a piston to push the folded proteins across the outer membrane through the secretin pore. The pseudopilus is composed of the major pseudopilin, EpsG, and four minor pseudopilins, EpsH, EpsI, EpsJ and EpsK. We determined the x-ray crystal structure of the head domain of EpsH at 1.59Å resolution using molecular replacement with the previously reported EpsH structure, 2qv8, as the template. Three additional N-terminal amino acids present in our construct prevent an artifactual conformation of residues 160-166, present in one of the two monomers of the 2qv8 structure. Additional crystal contacts stabilize a long flexible loop comprised of residues 104-135 that is more disordered in the 2qv8 structure but is partially observed in our structure in very different positions for the two EpsH monomers in the asymmetric unit. In one of the conformations the loop is highly extended. Modeling suggests the highly charged loop is capable of contacting EpsG and possibly secreted protein substrates, suggesting a role in specificity of pseudopilus assembly or secretion function.

    Video meteor observations provide us with data to analyze structures in minor meteor showers or weak features in flux profiles. Samples obtained independently by other techniques allow to calibrate the data sets and to improve the confidence of results as demonstrated with a few results. Both, the confirmation of events predicted by model calculation and the input of observational data to improve the modelling results may help to better understand meteoroid stream evolution processes. Furthermore, calibrated data series can be used for studies of the long-term evolution of meteor shower activity.

    The recent confirmation of the discovery of a satellite of the minor planet 532 Herculina indicates that other similar anomalous sightings are probably also due to satellites, which must therefore be numerous and commonplace. There are now 23 candidate satellites for eight minor planets, and no one of these minor planets occulting a star has failed to show evidence of at least one secondary event. Such companions are gravitationally stable but apparently have rapid tidal evolution rates.

    Upon attachment to their respective receptor, human rhinoviruses (HRVs) are internalized into the host cell via different pathways but undergo similar structural changes. This ultimately results in the delivery of the viral RNA into the cytoplasm for replication. To improve our understanding of the conformational modifications associated with the release of the viral genome, we have determined the X-ray structure at 3.0 Å resolution of the end-stage of HRV2 uncoating, the empty capsid. The structure shows important conformational changes in the capsid protomer. In particular, a hinge movement around the hydrophobic pocket of VP1 allows a coordinated shift of VP2 and VP3. This overall displacement forces a reorganization of the inter-protomer interfaces, resulting in a particle expansion and in the opening of new channels in the capsid core. These new breaches in the capsid, opening one at the base of the canyon and the second at the particle two-fold axes, might act as gates for the externalization of the VP1 N-terminus and the extrusion of the viral RNA, respectively. The structural comparison between native and empty HRV2 particles unveils a number of pH-sensitive amino acid residues, conserved in rhinoviruses, which participate in the structural rearrangements involved in the uncoating process.

  19. Clustered marginalization of minorities during social transitions induced by co-evolution of behaviour and network structure

    Large-scale transitions in societies are associated with both individual behavioural change and restructuring of the social network. These two factors have often been considered independently, yet recent advances in social network research challenge this view. Here we show that common features of societal marginalization and clustering emerge naturally during transitions in a co-evolutionary adaptive network model. This is achieved by explicitly considering the interplay between individual interaction and a dynamic network structure in behavioural selection. We exemplify this mechanism by simulating how smoking behaviour and the network structure get reconfigured by changing social norms. Our results are consistent with empirical findings: The prevalence of smoking was reduced, remaining smokers were preferentially connected among each other and formed increasingly marginalized clusters. We propose that self-amplifying feedbacks between individual behaviour and dynamic restructuring of the network are main drivers of the transition. This generative mechanism for co-evolution of individual behaviour and social network structure may apply to a wide range of examples beyond smoking. PMID:27510641

  2. Gamma ray sterilization of delta inulin adjuvant particles (Advax™) makes minor, partly reversible structural changes without affecting adjuvant activity.

    2014-01-23

    We earlier identified a developmental series of seven isoforms/polymorphs of microparticulate inulin by comparing non-covalent bonding strengths. Their pharmaceutical utility lies in the modulation of cellular immunity, exploited as vaccine adjuvants (Advax™) especially for delta inulin (DI). As such particles cannot be sterilized by filtration we explore the effect of (60)Co gamma radiation (GR) on inulin isoforms, particularly DI. Its adjuvant activity and overt physical properties were unaffected by normal GR sterilizing doses (up to 25kGy). Heating irradiated isoform suspensions near their critical dissolution temperature revealed increased solubility deduced to reflect a single lethal event in one component of a multi-component structure. Local oxidative effects of GR on DI were not found. The observed DI loss was almost halved by re-annealing at the critical temperature: surviving inulin chains apparently reassemble into smaller amounts of the original type of structure. Colorimetric tetrazolium assay revealed increases in reducing activity after GR of raw inulin powder, which yielded DI with normal physical properties but only 25% normal recovery yet 4× normal reducing ability, implying final retention of some GR-changed inulin chains. These findings suggest minimal inulin chain cleavage and confirm that GR may be a viable strategy for terminal sterilization of microparticulate inulin adjuvants.

    Praseodymium was used as the surrogate for trivalent minor actinide neptunium, and a complete series of pure monazite-type Ce1-xPrxPO4 (x = 0-1) solid solutions were successfully prepared by the solid state reaction. The effects of calcining temperature, holding time and Pr content on the structure of Ce1-xPrxPO4 solid solutions were investigated. The results show that although Pr6O11 (Pr23+Pr44+O11) exists two stabilized oxidation states, there has been no tetravalent praseodymium phosphate during the synthesis process. The optimized temperature for the synthesis of Ce0.8Pr0.2PO4 solid solution is more than 1100 °C, and a hypothetical reaction mechanism is also proposed. Besides, the crystalline grains coarsen as the increasing of holding time. The linear variation of unit cell parameters and a gradual hypsochromic shift in the Raman spectra are observed with the increase of Pr content, indicating that cerium is progressively replaced by praseodymium and Ce1-xPrxPO4 solid solutions were prepared.

  8. Right-angle pattern of minor fluvial networks from the Ionian terraced belt, southern Italy: passive structural control or foreland bending?

    whole study area, suggesting a control by a pervasive orthogonal fracture system rather than by isolated faults and/or master joints. Such a structural pattern and the arrangement of the terraces slope don't match very well with the tectonic features associated to a vertical uplift motion. Fractures were produced and preserved into the brittle caprock of the terraces, made by conglomerate, and exerted their control on the minor fluvial channels that progressively deepened into the underlying Pleistocene clay and sand, but they are not much represented in these soft rocks. Since a similar pervasive and orthogonal fracture pattern is actually generated by gentle folding of rocks, the development of the Ionian hydrographic networks could be attributed to a general - maybe still active - bending of the foredeep area due to the eastward propagation of blind thrusting of the Apennines chain.

    Seifertite SiO₂ likely exists as a minor phase near the core–mantle boundary. By simulating the pressure and temperature conditions near the core–mantle boundary, seifertite was synthesized as a minor phase in a coarse-grained, polycrystalline sample coexisting with the (Mg,Fe)SiO₃ post-perovskite (pPv) phase at 129 GPa and 2500 K. Here we report the first in situ single-crystal structure determination and refinement of seifertite at high pressure and after a temperature quench from laser heating. We improved the data coverage of a minor phase from a diamond-anvil cell (DAC) by merging single-crystal data of seifertite from six selected grains that had different orientations. Observed systematic absences of reflections from the six individual grains allowed only one space group: Pbcn. The refined results of seifertite are in good agreement with the predictions from previous first-principles calculations at high pressure. This approach provides a method for structure determination of a minor phase in a mineral assemblage synthesized under P-T conditions representative of the deep Earth.

    The overrepresentation of racial/ethnic minorities within the criminal justice system relative to their population percentage, a phenomenon termed disproportionate minority contact, has been examined within general adult and adolescent offender populations; yet few studies have tested whether this phenomenon extends to juvenile sexual offenders (JSOs). In addition, few studies have examined whether offender race/ethnicity influences registration and notification requirements, which JSOs are subject to in some U.S. states. The present study assessed for disproportionate minority contact among general delinquent offenders and JSOs, meaning it aimed to test whether the criminal justice system treats those accused of sexual and non-sexual offenses differently by racial/ethnic group. Furthermore, racial/ethnic group differences in risk, legal classification, and sexual offending were examined for JSOs. Results indicated disproportionate minority contact was present among juveniles with non-sexual offenses and JSOs in Alabama. In addition, offense category and risk scores differed between African American and European American JSOs. Finally, registration classifications were predicted by offending characteristics, but not race/ethnicity. Implications and future directions regarding disproportionate minority contact among JSOs and social and legal policy affecting JSOs are discussed.

    SUMMARY Understanding the mental health needs of lesbian and bisexual (sexual minority) women is an integral part of designing and providing appropriate mental health services and treatment for them. In an effort to understand the mental health needs of sexual minority women who seek community treatment, a chart review was conducted of the 223 lesbian and bisexual women who presented for services between July 1, 1997 and December 31, 2000 at Fenway Community Health in Boston, MA. Data are based on clients' self-reports and clinician assessments of clients' presenting problem, relevant developmental history, prior mental health and substance abuse treatment, current reports of emotional/psychological symptoms, and areas of impaired functioning. Although substance abuse and suicidal ideation were commonly reported problems, other concerns were more frequently reported. High percentages of lesbians and bisexual women reported relationship concerns and lack of adequate social networks; rates of depression and anxiety based on clinicians' assessments were also high. Overall, lesbians and bisexual women did not differ in the issues they brought to treatment or level or types of impairment. Compared with previous community survey samples, however, study participants appeared to be healthier than general, non-clinical samples of self-identified lesbians, possibly reflecting the special characteristics of sexual minority women who seek treatment in specialized community sites such as the Fenway. Although patients who come to these sites may not represent the more general population of sexual minority women, community health centers known to serve lesbian, gay, bisexual and transgender (LGBT) individuals may be fruitful access points for studying the mental health status and treatment needs of sexual minority women.

    The crystal structure of a left-handed Z-DNA hexamer, d(CG)(3) in complex with a synthetic polyamine, N(1)-[2-(2-amino-ethylamino)-ethyl]-ethane-1,2-diamine, NH(3)(+)-(CH(2))(2)-NH(2)(+)-(CH(2))(2)-NH(2)(+)-(CH(2))(2)-NH(3)(+) [PA(222)], has been determined by the X-ray diffraction method at 1.0 A resolution. In an orthorhombic crystal, the d(CG)(3) duplex binds two PA(222) molecules, and this synthetic polyamine exhibits dual conformational properties. One of the two PA(222) molecules resides on the floor of the minor groove of a Z-DNA duplex and imino groups bridge the two phosphate chains across a double helix, while the terminal amino groups link the oxygen atoms O2 of four cytosine bases. This PA(222) molecule makes a U-turn like a fishhook at one of its ends to provide a micro-environmental network previously unseen in complexes of DNA with polyamines. The width of the minor groove does not become considerably greater with the looped end of the polyamine, indicating conformational rigidity of the Z-DNA backbone imposed by the high stacking energy of the GC base pairs. While polyamine binding to the minor groove has been postulated by theoretical studies for stabilizing the Z-DNA double helical conformation, the finding in the crystal of the looped polyamine chain binding the minor groove of Z-DNA is observed for the first time from the data collected at 10 degrees C (so-called room temperature data). Another PA(222) molecule binds on the convex outer surface of the major groove of the Z-DNA duplex and links three d(CG)(3) duplexes which are symmetrically related to each other. The structure of this PA(222) presents the previously reported zig-zag type conformation [Egli et al., Biochemistry 30 (1991) 11388-11402]. Comparison of this structure with other polyamine-DNA cocrystals reveals structural themes and differences that may relate to the length of the polyamine.

    So far, the development of highly active and stable carbon-based electrocatalysts for oxygen reduction reaction (ORR) to replace commercial Pt/C catalyst is a hot topic. In this study, a new nanoporous nitrogen-doped carbon material was facilely designed by two-step pyrolysis of the renewable Lemna minor enriched in crude protein under a nitrogen atmosphere. Electrochemical measurements show that the onset potential for ORR on this carbon material is around 0.93 V (versus reversible hydrogen electrode), slightly lower than that on the Pt/C catalyst, but its cycling stability is higher compared to the Pt/C catalyst in an alkaline medium. Besides, the ORR at this catalyst approaches to a four-electron transfer pathway. The obtained ORR performance can be basically attributed to the formation of high contents of pyridinic and graphitic nitrogen atoms inside this catalyst. Thus, this work opens up the path in the ORR catalysis for the design of nitrogen-doped carbon materials utilizing aquatic plants as starting precursors.

    Findings from previous studies corroborate the hypothesis that universalism and conservation values are associated with negative attitudes toward immigration. In the current study we examine whether universalism and conservation values also play a critical role in the explanation of attitudes toward other minority groups. Drawing on previous research on group-focused enmity, we explore its relations with universalism and conservation values in a German sample. Employing structural equation modeling, we find that individuals who prioritize universalism values approve of various minorities more whereas those who prioritize conservation values exhibit more disapproval.

  2. BOOK REVIEW: Minority Games

    New branches of scientific disciplines often have a few paradigmatic models that serve as a testing ground for theories and a starting point for new inquiries. In the late 1990s, one of these models found fertile ground in the growing field of econophysics: the Minority Game (MG), a model for speculative markets that combined conceptual simplicity with interesting emergent behaviour and challenging mathematics. The two basic ingredients were the minority mechanism (a large number of players have to choose one of two alternatives in each round, and the minority wins) and limited rationality (each player has a small set of decision rules, and chooses the more successful ones). Combining these, one observes a phase transition between a crowded and an inefficient market phase, fat-tailed price distributions at the transition, and many other nontrivial effects. Now, seven years after the first paper, three of the key players—Damien Challet, Matteo Marsili and Yi-Cheng Zhang—have published a monograph that summarizes the current state of the science. The book consists of two parts: a 100-page overview of the various aspects of the MG, and reprints of many essential papers. The first chapters of Part I give a well-written description of the motivation and the history behind the MG, and then go into the phenomenology and the mathematical treatment of the model. The authors emphasize the `physics' underlying the behaviour and give coherent, intuitive explanations that are difficult to extract from the original papers. The mathematics is outlined, but calculations are not carried out in great detail (maybe they could have been included in an appendix). Chapter 4 then discusses how and why the MG is a model for speculative markets, how it can be modified to give a closer fit to observed market statistics (in particular, reproducing the `stylized facts' of fat-tailed distributions and volatility clustering), and what conclusions one can draw from the behaviour of the MG

    2006-05-01

    A review of observations and theories regarding binary asteroids and binary trans-Neptunian objects [collectively, binary minor planets (BMPs)] is presented. To date, these objects have been discovered using a combination of direct imaging, lightcurve analysis, and radar. They are found throughout the Solar System, and present a challenge for theorists modeling their formation in the context of Solar System evolution. The most promising models invoke rotational disruption for the smallest, shortest-lived objects (the asteroids nearest to Earth), consistent with the observed fast rotation of these bodies; impacts for the larger, longer-lived asteroids in the main belt, consistent with the range of size ratios of their components and slower rotation rates; and mutual capture for the distant, icy, trans-Neptunian objects, consistent with their large component separations and near-equal sizes. Numerical simulations have successfully reproduced key features of the binaries in the first two categories; the third remains to be investigated in detail.

    The purpose is to investigate and demonstrate equipment and techniques proposed for minor surgery on Space Station Freedom (SSF). The objectives are: (1) to test and evaluate methods of surgical instrument packaging and deployment; (2) to test and evaluate methods of surgical site preparation and draping; (3) to evaluate techniques of sterile procedure and maintaining sterile field; (4) to evaluate methods of trash management during medical/surgical procedures; and (4) to gain experience in techniques for performing surgery in microgravity. A KC-135 parabolic flight test was performed on March 30, 1990 with the goal of investigating and demonstrating surgical equipment and techniques under consideration for use on SSF. The flight followed the standard 40 parabola profile with 20 to 25 seconds of near-zero gravity in each parabola.

    The most potent tumorigen identified among the polycyclic aromatic hydrocarbons (PAH) is the nonplanar fjord region dibenzo[a,l]pyrene (DB[a,l]P). It is metabolically activated in vivo through the widely studied diol epoxide (DE) pathway to form covalent adducts with DNA bases, predominantly guanine and adenine. The (+)-11S,12R,13R,14S DE enantiomer forms adducts via its C14 position with the exocyclic amino group of guanine. Here, we present the first nuclear magnetic resonance solution structure of a DB[a,l]P-derived adduct, the 14R-(+)-trans-anti-DB[a,l]P-N(2)-dG (DB[a,l]P-dG) lesion in double-stranded DNA. In contrast to the stereochemically identical benzo[a]pyrene-derived N(2)-dG adduct (B[a]P-dG) in which the B[a]P rings reside in the B-DNA minor groove on the 3'-side of the modifed deoxyguanosine, in the DB[a,l]P-derived adduct the DB[a,l]P rings intercalate into the duplex on the 3'-side of the modified base from the sterically crowded minor groove. Watson-Crick base pairing of the modified guanine with the partner cytosine is broken, but these bases retain some stacking with the bulky DB[a,l]P ring system. This new theme in PAH DE-DNA adduct conformation differs from (1) the classical intercalation motif in which Watson-Crick base pairing is intact at the lesion site and (2) the base-displaced intercalation motif in which the damaged base and its partner are extruded from the helix. The structural considerations that lead to the intercalated conformation of the DB[a,l]P-dG lesion in contrast to the minor groove alignment of the B[a]P-dG adduct, and the implications of the DB[a,l]P-dG conformational motif for the recognition of such DNA lesions by the human nucleotide excision repair apparatus, are discussed.

    We investigated feared social situations in individuals with social anxiety disorder from different racial and ethnic groups in the United States. The sample included 247 African Americans, 158 Latinos, and 533 non-Latino Whites diagnosed with social anxiety disorder within the past 12 months from the integrated Collaborative Psychiatric Epidemiology Studies data set. After randomly splitting the full sample, we conducted an exploratory factor analysis with half of the sample to determine the structure of feared social situations in a more diverse sample than has been used in previous studies. We found evidence for a model consisting of three feared social domains: performance/public speaking, social interaction, and observational. We then conducted a confirmatory factor analysis on the remaining half of the sample to examine whether this factor structure varied significantly between the race-ethnic groups. Analyses revealed an adequate fit of this model across all three race-ethnic groups, suggesting invariance of the factor structure between the study groups. Broader cultural contexts within which these findings are relevant are discussed, along with important implications for comprehensive, culturally sensitive assessment of social anxiety.

    Derous, Eva

    2017-01-01

    Cross-cultural impression management (IM) has not been considered much, which is remarkable given the fast rate at which the labor market is becoming multicultural. This study investigated whether ethnic minorities and majorities differed in their preference for IM-tactics and how this affected ethnic minorities' interview outcomes. A preliminary study (focus groups/survey) showed that ethnic minorities (i.e., Arab/Moroccans) preferred 'entitlements' whereas majorities (i.e., Flemish/Belgians) preferred 'opinion conformity' as IM-tactics. An experimental follow-up study among 163 ethnic majority raters showed no main effect of IM-tactics on interview ratings. Ethnic minorities' use of IM-tactics only affected interview ratings if rater characteristics were considered. Specifically, interview ratings were higher when ethnic minorities used opinion conformity (i.e., majority-preferred IM-tactic) and lower when minorities used entitlements (i.e., minority-preferred IM-tactic) if recruiters were high in social dominance orientation, and when they felt more experienced/proficient with interviewing. IM-tactics are a human capital factor that might help applicants to increase their job chances on the labor market. It is concluded that ethnic minority applicants' preferences for certain IM-tactics might lead to bias even in structured interview settings, but that this depends on ethnic majority recruiters' interview experience and ingroup/outgroup attitudes. Implications for research and practice are discussed.

    Previous research indicates that lesbian, gay, and bisexual (LGB) adolescents are at increased risk for substance use, including heightened rates of marijuana use. Minority stress theory suggests that difficult social situations create a state of chronic stress that leads to poor health outcomes for LGB adults; however, the applicability of this model has not been well explored in relation to substance use among LGB adolescents. The current study is a secondary analysis of the OutProud survey, conducted in 2000. The original study used purposive sampling to collect data from 1,911 LGB adolescents (age 12-17) across the United States, and represents the largest known study to explore experiences specific to identifying as LGB, such as homophobia and gay-related victimization. We used structural equation modeling (SEM) to explore the feasibility of applying a minority stress framework to understand marijuana use in this population. The final structural model for marijuana use in the LGB adolescent sample displayed excellent fit and modest explanatory power for marijuana use. Two of the five factors, community connectedness and internalized homophobia, were significantly (p < .05) associated with marijuana use. Findings suggest that minority stress theory may be appropriately applied to marijuana use in this population; however, better measurement of minority stress concepts for LGB adolescents is needed.

  3. Minority workers or minority human beings? A European dilemma

    "European" identities may be politonymic, toponymic, ethnomyic or linguonymic (Bromley 1984). Each dimension may affect whether migrant minorities are treated as "European", and influence their schooling, integration and rights. Treatment and terminology vary in different states and periods of migration. However, the position for immigrated minorities is that they are still largely seen as workers rather than human beings with equal rights. Lack of success in schools is blamed on the migrants themselves rather than the educational system. This construction of migrants as being deficient is parallel to educational practice which falls within a UN definition of linguistic genocide, and contributes to mis-education. If current efforts in international bodies to codify educational linguistic human rights were to lead to greater support for minorities, this could assist in a redefinition of national identities and a reduction of racism and conflict.

  4. Minors and Sexting: Legal Implications.

    PubMed

    Lorang, Melissa R; McNiel, Dale E; Binder, Renée L

    2016-03-01

    Sexting is the sending or forwarding of sexually explicit photographs or videos of the sender or someone known to the sender via cell phone. It has become common practice among young people, as cell phones are being given to adolescents at ever younger ages. Youths often send messages without giving appropriate thought to the content of the images. In studies on the subject, rates of minors who have sent sexual images range from 4 to 25 percent, depending on the age of the youths surveyed, the content of the messages and other factors. Because transferring and viewing sexually explicit material when the subject is a minor can be considered child pornography, there can be serious legal consequences. Several states have enacted legislation to help differentiate between child pornography and sexting by minors. The trend reflected in statutes has been that minors involved in sexting without other exacerbating circumstances should be charged with a less serious offense. There is no clear national consensus on how sexting by minors is adjudicated, and therefore we compared several statutes. Case examples are used to illustrate the range of legal outcomes, from felony charges to no charges. Two sexting episodes that were followed by suicide are described. We also address the role of the forensic mental health professional.

  5. Structural dynamics of the box C/D RNA kink-turn and its complex with proteins: the role of the A-minor 0 interaction, long-residency water bridges, and structural ion-binding sites revealed by molecular simulations.

    Kink-turns (K-turns) are recurrent elbow-like RNA motifs that participate in protein-assisted RNA folding and contribute to RNA dynamics. We carried out a set of molecular dynamics (MD) simulations using parm99 and parmbsc0 force fields to investigate structural dynamics of the box C/D RNA and its complexes with two proteins: native archaeal L7ae protein and human 15.5 kDa protein, originally bound to very similar structure of U4 snRNA. The box C/D RNA forms K-turn with A-minor 0 tertiary interaction between its canonical (C) and noncanonical (NC) stems. The local K-turn architecture is thus different from the previously studied ribosomal K-turns 38 and 42 having A-minor I interaction. The simulations reveal visible structural dynamics of this tertiary interaction involving altogether six substates which substantially contribute to the elbow-like flexibility of the K-turn. The interaction can even temporarily shift to the A-minor I type pattern; however, this is associated with distortion of the G/A base pair in the NC-stem of the K-turn. The simulations show reduction of the K-turn flexibility upon protein binding. The protein interacts with the apex of the K-turn and with the NC-stem. The protein-RNA interface includes long-residency hydration sites. We have also found long-residency hydration sites and major ion-binding sites associated with the K-turn itself. The overall topology of the K-turn remains stable in all simulations. However, in simulations of free K-turn, we observed instability of the key C16(O2')-A7(N1) H-bond, which is a signature interaction of K-turns and which was visibly more stable in simulations of K-turns possessing A-minor I interaction. It may reflect either some imbalance of the force field or it may be a correct indication of early stages of unfolding since this K-turn requires protein binding for its stabilization. Interestingly, the 16(O2')-7(N1) H- bond is usually not fully lost since it is replaced by a water bridge with a tightly

  13. Fast clique minor generation in Chimera qubit connectivity graphs

    NASA Astrophysics Data System (ADS)

    Boothby, Tomas; King, Andrew D.; Roy, Aidan

    2016-01-01

    The current generation of D-Wave quantum annealing processor is designed to minimize the energy of an Ising spin configuration whose pairwise interactions lie on the edges of a Chimera graph C_{M,N,L}. In order to solve an Ising spin problem with arbitrary pairwise interaction structure, the corresponding graph must be minor-embedded into a Chimera graph. We define a combinatorial class of native clique minors in Chimera graphs with vertex images of uniform, near minimal size and provide a polynomial-time algorithm that finds a maximum native clique minor in a given induced subgraph of a Chimera graph. These minors allow improvement over recent work and have immediate practical applications in the field of quantum annealing.

  1. Isolation and characterization of a minor fimbria from Porphyromonas gingivalis.

    PubMed Central

    Hamada, N; Sojar, H T; Cho, M I; Genco, R J

    1996-01-01

    We have discovered two distinctly different fimbriae expressed by the same Porphyromonas gingivalis strain. The construction of a fimA mutant of P. gingivalis ATCC 33277 has previously been reported by N. Hamada et al. (Infect. Immun. 62:1696-1704, 1994). Expression of fimbriae on the surface of the fimA mutant and the wild-type strain, ATCC 33277, were investigated by electron microscopy. The wild-type strain produced long fimbrial structures extending from the cell surface, whereas those structures were not observed on the fimA mutant. However, short fimbrial structures were seen on the surface of the fimA mutant. The short fimbrial protein was purified from the fimA mutant by selective protein precipitation and chromatography on DEAE Sepharose CL-6B. We have found that the second fimbrial structure of P. gingivalis ATCC 33277 is distinct from the 41-kDa (43-kDa) major fimbrial protein (FimA). We provisionally call this protein minor fimbriae. The molecular mass of the minor fimbriae is 67 kDa as estimated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis under reducing conditions after boiling at 100 degrees C. The component shows a ladder-like pattern at 80 degrees C under nonreducing conditions, suggesting a tendency to aggregate or polymerize. In immunoblotting analysis, anti-minor fimbria serum reacted with both the 100 degrees C- and the 80 degrees C-treated minor fimbriae. The anti-minor fimbria serum also reacts with the same-molecular-size fimbrial preparation from the wild-type strain. Immunogold electron microscopy showed that the anti-minor fimbria serum bound to the minor fimbria on the cell surface of the wild-type strain. This is the first report on the identification of the minor fimbria produced by P. gingivalis. These results suggest that the minor fimbriae appearing on the fimA mutant strain are produced together with numerous long major fimbriae on the wild-type strain. Moreover, the minor fimbriae are different in size and

  2. Minority stress and physical health among sexual minority individuals.

    2015-02-01

    This study examined the effects of minority stress on the physical health of lesbians, gay men, and bisexuals (LGBs). Participants (N = 396) completed baseline and one year follow-up interviews. Exposure to stress and health outcomes were assessed with two methods: a subjective self-appraisal method and a method whereby two independent judges externally rated event narratives using standardized criteria. The odds of experiencing a physical health problem at follow-up were significantly higher among LGBs who experienced an externally rated prejudice event during the follow-up period compared to those who did not. This association persisted after adjusting for experiences of general stressful life events that were not related to prejudice. Self-appraised minority stress exposures were not associated with poorer physical health at 1-year follow-up. Prejudice-related stressful life events have a unique deleterious impact on health that persists above and beyond the effect of stressful life events unrelated to prejudice.

  3. The Nabataeans and Asia Minor

    NASA Astrophysics Data System (ADS)

    Salameen, Z. al

    The Nabataean period (c. 312 BC- AD 106) stands out as a period of prosperity, expansion, cultural growth and a relative political unity. It is clear that the Nabataean commercial activities as well as their involvement in the lucrative trade of aromatics had been the major acknowledged influence on the Nabataean urban settlements, economic development and architectural renaissance. This paper focuses on the international Nabataean relations with the west and their influences on the Nabataean cultural achievements. The specific question of this work investigates the influence of international maritime and long distance trade as well as the influence of Asia Minor on the Nabataean culture. It discusses the south-western Asia Minor archaeological evidence uncovered in Nabataea. Attention focuses on the nature and extent of the Nabataean material remains found in the Mediterranean and south west Anatolia and discusses the south-western Anatolian influence on the cultural achievements of the Nabataeans.

  4. Workforce utilization of visible and linguistic minorities in Canadian nursing.

    PubMed

    Premji, Stephanie; Etowa, Josephine B

    2014-01-01

    Aim  This study seeks to develop a diversity profile of the nursing workforce in Canada and its major cities. Background  There is ample evidence of ethnic and linguistic segregation in the Canadian labour market. However, it is unknown if there is equitable representation of visible and linguistic minorities in nursing professions. Methods  We cross-tabulated aggregate data from Statistics Canada's 2006 Census. Analyses examined the distribution of visible and linguistic minorities, including visible minority sub-groups, among health managers, head nurses, registered nurses, licensed nurses and nurse aides for Canada and major cities as well as by gender. Results  In Canada and its major cities, a pyramidal structure was found whereby visible and linguistic minorities, women in particular, were under-represented in managerial positions and over-represented in lower ranking positions. Blacks and Filipinos were generally well represented across nursing professions; however, other visible minority sub-groups lacked representation. Conclusions  Diversity initiatives at all levels can play a role in promoting better access to and quality of care for minority populations through the increased cultural and linguistic competence of care providers and organizations. Implications for Nursing Management  Efforts to increase diversity in nursing need to be accompanied by commitment and resources to effectively manage diversity within organizations.

  12. Properties of interaction networks underlying the minority game.

    PubMed

    Caridi, Inés

    2014-11-01

    The minority game is a well-known agent-based model with no explicit interaction among its agents. However, it is known that they interact through the global magnitudes of the model and through their strategies. In this work we have attempted to formalize the implicit interactions among minority game agents as if they were links on a complex network. We have defined the link between two agents by quantifying the similarity between them. This link definition is based on the information of the instance of the game (the set of strategies assigned to each agent at the beginning) without any dynamic information on the game and brings about a static, unweighed and undirected network. We have analyzed the structure of the resulting network for different parameters, such as the number of agents (N) and the agent's capacity to process information (m), always taking into account games with two strategies per agent. In the region of crowd effects of the model, the resulting networks structure is a small-world network, whereas in the region where the behavior of the minority game is the same as in a game of random decisions, networks become a random network of Erdos-Renyi. The transition between these two types of networks is slow, without any peculiar feature of the network in the region of the coordination among agents. Finally, we have studied the resulting static networks for the full strategy minority game model, a maximal instance of the minority game in which all possible agents take part in the game. We have explicitly calculated the degree distribution of the full strategy minority game network and, on the basis of this analytical result, we have estimated the degree distribution of the minority game network, which is in accordance with computational results.

  14. Strategies employed by sexual minority adolescents to cope with minority stress

    PubMed Central

    Goldbach, J.T.; Gibbs, J.J.

    2015-01-01

    Sexual minority adolescents (SMA) experience disparities in health and behavioral health outcomes, including high rates of depression, anxiety, self-harm, substance use, HIV risk behavior, suicidal ideation, and suicide attempts. These outcomes are commonly attributed to minority stress. Stress experiences are different for SMA than their adult counterparts. For example, disclosing their sexual orientation may be more likely to result in homelessness because these youth more often live with parents or other family members. Although stress in this population has been explored in previous research, very little is known about how SMA cope. Relying upon an adolescent coping model, this study examined the coping strategies, responses, and resources of SMA related to stress. Forty-eight racially and ethnically diverse SMA (age 14–19) were recruited for 90-minute tape-recorded interviews. The semi-structured interviews were guided by a life history calendar. Recordings were transcribed verbatim and entered into QSR NVivo. All transcripts were coded by two members of the research team and went through a consensus process. Forty-three unique coping statements emerged that fit with the Compas model of adolescent coping. SMA cope with minority stress in similar ways to heterosexual youth coping with general stress, but findings suggest that SMA may also use different kinds of coping resources. Although further research is needed, the present study identified a variety of ways SMA cope with stress and can inform future research on the development interventions. PMID:26634221

  4. Minority Stress and Physical Health Among Sexual Minorities.

    PubMed

    Lick, David J; Durso, Laura E; Johnson, Kerri L

    2013-09-01

    Lesbian, gay, and bisexual (LGB) individuals suffer serious mental health disparities relative to their heterosexual peers, and researchers have linked these disparities to difficult social experiences (e.g., antigay victimization) and internalized biases (e.g., internalized homophobia) that arouse stress. A recent and growing body of evidence suggests that LGB individuals also suffer physical health disparities relative to heterosexuals, ranging from poor general health status to increased risk for cancer and heightened diagnoses of cardiovascular disease, asthma, diabetes, and other chronic conditions. Despite recent advances in this literature, the causes of LGB physical health problems remain relatively opaque. In this article, we review empirical findings related to LGB physical health disparities and argue that such disparities are related to the experience of minority stress-that is, stress caused by experiences with antigay stigma. In light of this minority stress model, we highlight gaps in the current literature and outline five research steps necessary for developing a comprehensive knowledge of the social determinants of LGB physical health.

  5. Minor Actinides Recycling in PWRs

    SciTech Connect

    Delpech, M.; Golfier, H.; Vasile, A.; Varaine, F.; Boucher, L.; Greneche, D.

    2006-07-01

    Recycling of minor actinides in current and near future PWR is considered as one of the options of the general waste management strategy. This paper presents the analysis of this option both from the core physics and fuel cycle point of view. A first indicator of the efficiency of different neutron spectra for transmutation purposes is the capture to fission cross sections ratio which is less favourable by a factor between 5 to 10 in PWRs compared to fast reactors. Another indicator presented is the production of high ranking isotopes like Curium, Berkelium or Californium in the thermal or epithermal spectrum conditions of PWR cores by successive neutron captures. The impact of the accumulation of this elements on the fabrication process of such PWR fuels strongly penalizes this option. The main constraint on minor actinides loadings in PWR (or fast reactors) fuels are related to their direct impact (or the impact of their transmutation products) on the reactivity coefficients, the reactivity control means and the core kinetics parameters. The main fuel cycle physical parameters like the neutron source, the alpha decay power, the gamma and neutrons dose rate and the criticality aspects are also affected. Recent neutronic calculations based on a reference core of the Evolutionary Pressurized Reactor (EPR), indicates typical maximum values of 1 % loadings. Different fuel design options for minor actinides transmutation purposes in PWRs are presented: UOX and MOX, homogeneous and heterogeneous assemblies. In this later case, Americium loading is concentrated in specific pins of a standard UOX assembly. Recycling of Neptunium in UOX and MOX fuels was also studied to improve the proliferation resistance of the fuel. The impact on the core physics and penalties on Uranium enrichment were underlined in this case. (authors)

  8. Minor elements in Keweenawan lavas, Michigan

    USGS Publications Warehouse

    Cornwall, H.R.; Rose, H.J.

    1957-01-01

    The distribution of minor elements in three basaltic flows of the Keweenawan series, of Michigan, is related to differentiation in the flows. Thus, nickel is most abundant in the early differentiates; nickel, chromium, and barium are generally deficient in the pegmatites, which formed late; whereas copper, vanadium, yttrium, and other minor elements are concentrated in the pegmatites. The minor-element content of individual minerals in the Greenstone flow varies markedly from one mineral to another and seems to depend primarily on the presence or absence in the minerals of major elements for which the minor elements can substitute. Minor elements have substituted most readily for those major elements with similar ionic radii. Valence and electronegativity also seem to influence the ease of substitution. The distribution of other minor elements in copper-bearing lodes of the Michigan copper district shows no apparent relation to copper mineralization. ?? 1957.

  11. THE STRUCTURES AND TOTAL (MINOR + MAJOR) MERGER HISTORIES OF MASSIVE GALAXIES UP TO z {approx} 3 IN THE HST GOODS NICMOS SURVEY: A POSSIBLE SOLUTION TO THE SIZE EVOLUTION PROBLEM

    We investigate the total major (>1:4 by stellar mass) and minor (>1:100 by stellar mass) merger history of a population of 80 massive (M{sub *} > 10{sup 11} M{sub Sun }) galaxies at high redshifts (z = 1.7-3). We utilize extremely deep and high-resolution Hubble Space Telescope H-band imaging from the GOODS NICMOS Survey, which corresponds to rest-frame optical wavelengths at the redshifts probed. We find that massive galaxies at high redshifts are often morphologically disturbed, with a CAS (concentration, C; asymmetry, A; clumpiness, S) deduced merger fraction f{sub m} = 0.23 {+-} 0.05 at z = 1.7-3. We find close accord between close pair methods (within 30 kpc apertures) and CAS methods for deducing major merger fractions at all redshifts. We deduce the total (minor + major) merger history of massive galaxies with M{sub *} > 10{sup 9} M{sub Sun} galaxies, and find that this scales roughly linearly with log-stellar-mass and magnitude range. We test our close pair methods by utilizing mock galaxy catalogs from the Millennium Simulation. We compute the total number of mergers to be (4.5 {+-} 2.9)/({tau}{sub m}) from z = 3 to the present, to a stellar mass sensitivity threshold of {approx}1:100 (where {tau}{sub m} is the merger timescale in Gyr which varies as a function of mass). This corresponds to an average mass increase of (3.4 {+-} 2.2) Multiplication-Sign 10{sup 11} M{sub Sun} over the past 11.5 Gyr due to merging. We show that the size evolution observed for these galaxies may be mostly explained by this merging.

  12. Micromechanics of Minor Cervical Spine Injuries

    NASA Astrophysics Data System (ADS)

    Niederer, Peter F.; Schmitt, Kai-Uwe; Muser, Markus H.; Walz, Felix H.

    Minor soft tissue injuries of the cervical spine are of increasing significance in public health. They may in particular be associated with long-term impairment. Such injuries are observed primarily in rear-end automobile collisions at low impact speeds and are attributed to a “whiplash”-type event. The question with respect to injury mechanisms of the cervical spine in cases of impacts of a low severity have raised controversial views in the past. Among proposed injury mechanisms, interactions between fluid and solid structures have been postulated: Viscous shear stresses or pressure gradients which arise in the deforming anatomical structures may have an adverse influence, e. g., on cellular membranes. In this communication, mathematical modeling approaches are presented which allow for a quantification of fluid/solid interactions under typical loading conditions of interest here. It is found, that the shear stresses caused by fluids and acting on accelerated surfaces of fluid-filled bodies depend largely on the size of the fluid space under consideration. Accelerations exhibit a stronger influence than their duration. It cannot be excluded that critical levels are reached even in a low speed impact scenario.

    1992-01-01

    This report documents the program and data used to identify known asteroids observed by the Infrared Astronomical Satellite (IRAS) and to compute albedos and diameters from their IRAS fluxes. It also presents listings of the results obtained. These results supplant those in the IRAS Asteroid and Comet Survey, 1986. The present version used new and improved asteroid orbital elements for 4679 numbered asteroids and 2632 additional asteroids for which at least two-opposition elements were available as of mid-1991. It employed asteroid absolute magnitudes on the International Astronomical Union system adopted in 1991. In addition, the code was modified to increase the reliability of associating asteroids with IRAS sources and rectify several shortcomings in the final data products released in 1986. Association reliability was improved by decreasing the position difference between an IRAS source and a predicted asteroid position required for an association. The shortcomings addressed included the problem of flux overestimation for low SNR sources and the systematic difference in albedos and diameters among the three wavelength bands (12, 25, and 60 micrometers). Several minor bugs in the original code were also corrected.

  5. Minority issues in prostate disease.

    French, Dan B; Jones, LeRoy A

    2005-07-01

    This article has discussed the increased incidence and disproportionately increased mortality of prostate cancer among African American men.Although the exact reasons are unknown, genetics may play a role, in addition to health care practices. Morbidity from other disease states, such as diabetes, obesity, or hypertension, may influence the overall survival of patients with prostate cancer. Current research tools will continue to explore biologic differences between the races; however, socioeconomic status and access to health care must not be overlooked. Several studies have demonstrated that similar disease stages and equal access to health care will result in similar outcomes. It is recognized that screening for prostate cancer will remain a controversial topic. Several influential professional societies recommend against screening and other professional societies endorse screening. Large-scale trials are currently underway hoping to answer this critical question. Since the advent of current screening tools, however, it seems that the overall mortality for prostate cancer has decreased and this cannot be ignored. Certainly, screening programs and clinical trials have traditionally had difficulty in recruiting minority participants, although more recent trials seem to be finding success. A primary care physician who is viewed as competent by their patients can certainly have a positive impact on their African American patients' willingness to participate in studies and screening programs. Most importantly, on the individual level, primary care physicians can provide a great service to their minority patients by offering educational materials on prostate cancer and by offering screening to qualified patients. The current American Urologic Association and National Cancer Institute guidelines recommend offering screening to all men age 50 and above. African American men or men with a first-degree relative with prostate cancer should be offered screening beginning at

    Abstract Background Lesbian and bisexual (i.e., sexual minority) identity is more common among women veterans than among male veterans. Unique health issues have been identified among women veterans and among sexual minority women, but little is known about women who are both sexual minorities and veterans. This study aimed to compare demographic and health information from sexual minority women veterans with sexual minority women non-veterans and heterosexual women veterans. Methods Behavioral Risk Factor Surveillance Survey data were pooled from ten U.S. states that elected to ask sexual identity during 2010. The analytic sample was comprised of women who identified both their sexual identity and veteran status (n=1,908). Mental health indicators were frequent mental distress, sleep problems, low social/emotional support, and low satisfaction with life. Health risk indicators included current smoking, overweight, and obesity. Physical health status was defined by three components: disability requiring assistive equipment, >14 days of poor physical health in the past 30 days, and activity limitations. Results Compared with heterosexual women veterans, sexual minority women veterans had higher odds of mental distress (odds ratio [OR]=3.03, 95% confidence interval [CI]: 1.61–5.70) and smoking (OR=2.31, 95%CI: 1.19–4.48). After adjusting for demographic correlates, sexual minority women veterans had three times the odds of poor physical health (OR=3.01, 95%CI: 1.51–5.99) than their sexual minority non-veteran peers. Conclusions Results suggest sexual minority women veterans may experience unique health disparities relevant to provision of care in both Veterans Affairs (VA) and non-VA healthcare systems. Future research requires availability of data that include sexual minority status. PMID:23746281

  7. Minor Groove Deformability of DNA: A Molecular Dynamics Free Energy Simulation Study

    2006-01-01

    The conformational deformability of nucleic acids can influence their function and recognition by proteins. A class of DNA binding proteins including the TATA box binding protein binds to the DNA minor groove, resulting in an opening of the minor groove and DNA bending toward the major groove. Explicit solvent molecular dynamics simulations in combination with the umbrella sampling approach have been performed to investigate the molecular mechanism of DNA minor groove deformations and the indirect energetic contribution to protein binding. As a reaction coordinate, the distance between backbone segments on opposite strands was used. The resulting deformed structures showed close agreement with experimental DNA structures in complex with minor groove-binding proteins. The calculated free energy of minor groove deformation was ∼4–6 kcal mol−1 in the case of a central TATATA sequence. A smaller equilibrium minor groove width and more restricted minor groove mobility was found for the central AAATTT and also a significantly (∼2 times) larger free energy change for opening the minor groove. The helical parameter analysis of trajectories indicates that an easier partial unstacking of a central TA versus AT basepair step is a likely reason for the larger groove flexibility of the central TATATA case.

    This article focuses on my interpretation of the history of ethnic minority psychology, using as a base the presentations of the contributing authors to this special issue of Cultural Diversity and Ethnic Minority Psychology. Because each contributing author has focused on a particular ethnic group or a particular aspect of history, my goal is to focus on 3 common issues and problems. First, what are the themes and issues that confronted African Americans, American Indians and Alaska Natives, Asian Americans, and Latinos? Second, what were characteristics of the ethnic leaders on whose shoulders we now stand? Third, what kinds of relationships existed between members of different ethnic minority groups?

    It is important for the field of physics that we draw our talent from the broadest pool. However, African Americans, Hispanic Americans, and Native Americans are substantially underrepresented in physics. Since summer research experiences are a useful tool to assist students in gaining entrance into graduate school, it is particularly important that underrepresented minority students are fully able to participate. The NSF REU program at Vanderbilt University is historically comprised of one half minority students. How this comes about and how we pro-actively recruit minority students will be described.

    There is evidence of health disparities between sexual minority and heterosexual populations. Although the focus of lesbian, gay, bisexual, and transgender health research has been human immunodeficiency virus/acquired immunodeficiency syndrome and sexually transmitted infection among men who have sex with men, there are health disparities among sexual minority women. Using the minority stress framework, these disparities may in part be caused by individual prejudice, social stigma, and discrimination. To ensure equitable health for all, there is urgent need for targeted culturally sensitive health promotion, cultural sensitivity training for health care providers, and intervention-focused research.

    Narratives from 33 sexual minority women were examined to discover what factors contributed to their ability to acquire academic success, and what, if any, attributions are evident in some sexual minority women's experiences that provide the ability to persist and graduate. Coping strategies the participants used to gain the resiliency and persistence necessary to acquire academic success are discussed. Intrinsic themes were work ethic values, altruism, and self-efficacy. Extrinsic themes were mentors, family, and friends. Sexual minority women identified the complexity of intrinsic and extrinsic attributions that were used to successfully complete a four-year undergraduate degree in the United States.

    Two studies tested a model, whereby, identification with the minority group was predicted to impact on acculturation preferences, which in turn were proposed to impact involvement in intragroup friendships with other minority members, intergroup friendships with majority members and stress experienced by minority members. A direct path from minority identification to stress was also included in the model. The model was tested using structural equation modelling on survey data collected from Muslim women (N = 250) and from Somali minority members (N = 198) in Britain. Results supported predictions and revealed that identification was associated with more culture maintenance preference and less culture adoption preference. Culture maintenance preference was associated with involvement in intragroup friendships, and culture adoption preference was associated with involvement in intergroup friendships and increased stress. Practical applications of the findings are discussed.

  13. A review of minor surgery in general practice in the United Kingdom.

    Few general practitioners in the United Kingdom do minor surgery, in contrast to their colleagues in other countries. The reasons are largely historical and relate to the structure and function of the National Health Service. This history of minor surgery describes its common occurrence before the NHS, its virtual disappearance after the NHS came about, and later revival by a few enthusiasts. The state of the art describes the wide range of surgical procedures in general surgery, orthopaedics, ear-nose-and-throat, gynaecology and ophthalmology. There are few complications, and very short waiting times in general practice minor surgery. The workload is not great. Economic studies show great saving may be made. Patients strongly prefer general practice minor surgery. In conclusion, despite many advantages, there remain major financial disadvantages for general practitioners in the United Kingdom to provide minor surgery for their patients.

  14. RNA tertiary interactions in the large ribosomal subunit: The A-minor motif

    Analysis of the 2.4-{angstrom} resolution crystal structure of the large ribosomal subunit from Haloarcula marismortui reveals the existence of an abundant and ubiquitous structural motif that stabilizes RNA tertiary and quaternary structures. This motif is termed the A-minor motif, because it involves the insertion of the smooth, minor groove edges of adenines into the minor groove of neighboring helices, preferentially at C-G base pairs, where they form hydrogen bonds with one or both of the 2' OHs of those pairs. A-minor motifs stabilize contacts between RNA helices, interactions between loops and helices, and the conformations of junctions and tight turns. The interactions between the 3' terminal adenine of tRNAs bound in either the A site or the P site with 23S rRNA are examples of functionally significant A-minor interactions. The A-minor motif is by far the most abundant tertiary structure interaction in the large ribosomal subunit; 186 adenines in 23S and 5S rRNA participate, 68 of which are conserved. It may prove to be the universally most important long-range interaction in large RNA structures.

    Recent research efforts in oral biology have resulted in elucidation of the proteomes of major human salivary secretions and whole saliva. One might hypothesize that the proteome of minor gland secretions may show significantly different characteristics when compared with the proteomes of parotid or submandibular/sublingual secretions. To test this hypothesis, we conducted the first exploration into the proteome of minor salivary gland secretion. Minor gland secretion was obtained from healthy volunteers, and its components were subjected to liquid-chromatography-electrospray-ionization-tandem-mass-spectrometry. This led to the identification of 56 proteins, 12 of which had never been identified in any salivary secretion. The unique characteristics of the minor salivary gland secretion proteome are related to the types as well as the numbers of components present. The differences between salivary proteomes may be important with respect to specific oral functions.

    Official language minorities (Francophones outside of Quebec and Anglophones in Quebec) make up about 6.4% of the Canadian population. Even though the Canadian constitution gives legal equality status to French and English, there is still room to ask if this equality is maintained in the health sector. In other words, do Francophone and Anglophone communities of Canada have the same health profiles regardless of their minority or majority status? Do they have access to the same health services and in the same conditions? The objective of this paper is to identify the health issues associated with belonging to a linguistic minority. Our research allows us to highlight the social and health disparities that can be attributed to belonging to a minority. In the Canadian context, which has two official languages, an equitable health policy will have to take into consideration language as a determinant of health. PMID:24289938

    US minority health issues involve racial/ethnic disparities that affect both women and men. However, women's health advocacy in the United States does not consistently address problems specific to minority women. The underlying evolution and political strength of the women's health and minority health movements differ profoundly. Women of color comprise only one quarter of women's health movement constituents and are, on average, socioeconomically disadvantaged. Potential alliances may be inhibited by vestiges of historical racial and social divisions that detract from feelings of commonality and mutual support. Nevertheless, insufficient attention to minority women's issues undermines the legitimacy of the women's health movement and may prevent important advances that can be achieved only when diversity is fully considered.

  5. Faster Parameterized Algorithms for Minor Containment

    Adler, Isolde; Dorn, Frederic; Fomin, Fedor V.; Sau, Ignasi; Thilikos, Dimitrios M.

    The theory of Graph Minors by Robertson and Seymour is one of the deepest and significant theories in modern Combinatorics. This theory has also a strong impact on the recent development of Algorithms, and several areas, like Parameterized Complexity, have roots in Graph Minors. Until very recently it was a common belief that Graph Minors Theory is mainly of theoretical importance. However, it appears that many deep results from Robertson and Seymour's theory can be also used in the design of practical algorithms. Minor containment testing is one of algorithmically most important and technical parts of the theory, and minor containment in graphs of bounded branchwidth is a basic ingredient of this algorithm. In order to implement minor containment testing on graphs of bounded branchwidth, Hicks [NETWORKS 04] described an algorithm, that in time O(3^{k^2}\\cdot (h+k-1)!\\cdot m) decides if a graph G with m edges and branchwidth k, contains a fixed graph H on h vertices as a minor. That algorithm follows the ideas introduced by Robertson and Seymour in [J'CTSB 95]. In this work we improve the dependence on k of Hicks' result by showing that checking if H is a minor of G can be done in time O(2^{(2k +1 )\\cdot log k} \\cdot h^{2k} \\cdot 2^{2h^2} \\cdot m). Our approach is based on a combinatorial object called rooted packing, which captures the properties of the potential models of subgraphs of H that we seek in our dynamic programming algorithm. This formulation with rooted packings allows us to speed up the algorithm when G is embedded in a fixed surface, obtaining the first single-exponential algorithm for minor containment testing. Namely, it runs in time 2^{O(k)} \\cdot h^{2k} \\cdot 2^{O(h)} \\cdot n, with n = |V(G)|. Finally, we show that slight modifications of our algorithm permit to solve some related problems within the same time bounds, like induced minor or contraction minor containment.

    Transient photoluminescence is used to measure the minority carrier lifetime on n-type and p-type InP wafers. The measurements show that unprocessed InP wafers have very high minority carrier lifetimes. Lifetimes of 200 ns and 700 ns were observed for lightly-doped p- and n-type material respectively. Lifetimes over 5 ns were found in heavily doped n-type material.

    This article concentrates on the influence of determinants of mental health on a lesbian, gay, and bisexual (LGB) population in Flanders. Our sample is drawn from the Zzzip survey, and contains 2,280 LGBs, of whom 1,565 are men and 715 are women. The traditional social stress model outlines the influence of general stressors on stress (Pearlin, 1989). Meyer (1995) has expanded Pearlin's model to include the concept of minority stress. This study focuses on aspects of personal characteristics and social structural arrangements. Our study confirms the importance of age and education as relevant determinants for mental health. Additionally, although most research establishes sex differences in depression, this study does not find significant differences in depression between men and women. In women, sexual identity is a significant determinant of depressive score, but we do not find the same in men. Finally, both general and minority stressors, especially the internal stressors, are found to have an important effect on depressive outcomes.

    Size evolution studies have shown that the structural properties of the elliptical galaxies dramatically changed with cosmic time (e. g. Trujillo et al. 2007). This result challenges the ideas developed from the detailed analyses of the stellar populations of these galaxies in the nearby universe. The study of the local elliptical galaxies has revealed their stars are old, and formed over short-timescales (see the review by Renzini 2006). In order to resolve this discrepancy, it has been hypothesized that new material continuously accretes in minor merger events (Naab et al. 2007). Index-index diagrams are a promising way to probe the minor merger scenario. However, a large sample of galaxies is required for this goal. In this poster we present our preliminary index measurements of a subsample of galaxies studied by Trujillo et al. (2007) using the spectra published by the DEEP2 DR4 survey (Newman et al. 2012).

    Summertime has emerged as a high-risk period for weight gain among low-income minority youth who often experience a lack of resources when not attending school. Structured programming may be an effective means of reducing risk for obesity by improving obesogenic behaviors among these youth. The current multi-method study examined sedentary time, physical activity, and dietary intake among low-income urban minority girls in two contexts: an unstructured summertime setting and in the context of a structured 4-week community-based summer day camp program promoting physical activity. Data were analyzed using paired-sample t tests and repeated-measure analyses of variance with significance at the p < .05 level. Results evidenced no significant differences in total calories and fat consumed between the unstructured and structured settings. Participants exhibited significant increases in fruit consumption and physical activity and significant decreases in sedentary time of over 2 h/day and dairy consumption when engaged in structured summer programming. All improvements were independent of weight status and age, and African-American participants evidenced greater changes in physical activity during programming. The study concludes that structured, community-based summertime programming may be associated with fewer obesogenic behaviors in low-income urban youth and may be a powerful tool to address disparities in weight gain and obesity among high-risk samples.

  12. The truth about mentoring minorities. Race matters.

    2001-04-01

    Diversity has become a top priority in corporate America. Despite corporations' best intentions, however, many have failed to achieve a racial mix at the top levels of management. Some have revolving doors for talented minorities, recruiting the best and brightest, only to see them leave, frustrated by their experiences. Others are able to retain high-potential professionals of color but find them mired in middle management. To understand the different career trajectories of whites and minorities, David Thomas studied the progression of racial minorities at three large U.S. corporations. Here, he explains the three career stages that all professionals advance through, and he discusses why promising white professionals tend to enter fast tracks early in their careers, whereas high-potential minorities typically take off after they have reached middle management. Thomas's research shows that minorities who advance the furthest share one characteristic: a strong network of mentors and corporate sponsors. He found that minorities who plateaued in middle management received mentoring that was basically instructional; it helped them to develop skills. By contrast, minorities who became executives enjoyed fuller developmental relationships with their mentors. Thomas explains the types of support mentors provide for their protégés and outlines the challenges of mentoring across racial lines. Specifically, he addresses negative stereotypes, public scrutiny, difficulty with role modeling, and peer resentment. Finally, Thomas challenges the notion that the job of mentors begins and ends with their one-on-one relationships with their protégés. He offers concrete advice on how mentors can support broader initiatives at their organizations to create and enhance conditions that foster the upward mobility of professionals of color.

  13. We Can Recruit Minorities Into The Geosciences

    Despite the dismal numbers, efforts to recruit minorities into the geosciences are improving, thanks in part to NSF's "Opportunities for Enhancing Diversity in the Geosciences" (OEDG) initiative. At Wesleyan University, a small liberal arts college in Connecticut, we have significantly increased our recruitment of minority students. Twenty percent (four students) of the class of 2013 are African American. Most of the recruitment is done on an individual basis and working in conjunction with the "Dean for Diversity and Student Engagement" and courting minority students in introductory classes. The Dean for Diversity and Student Engagement is aware of our interest in increasing diversity and that we are able to hire minority students during the academic year and through the summer with OEDG funds. When she identifies minority students who might be interested in the geosciences, she refers them to faculty in the Earth and Environmental Sciences Department. Our faculty can provide employment, mentoring and a variety of geo-related experiences. Courting students in introductory courses can include inviting them to lunch or other activity, and attending sports, theater or dance events in which they are participating. Not all efforts result in new majors. Courses in ancillary sciences may be stumbling blocks and higher grades in less demanding courses have lured some students into other majors. Nevertheless, we now have a large enough cohort of minority students so that minority students from other majors visit their friends in our labs. A critical mass? Even a student, who chooses another major, may continue an interest in geoscience and through outreach efforts and discussions with younger family members, may provide a bridge that becomes a conduit for future students.

  14. The shape of the DNA minor groove directs binding by the DNA-bending protein Fis

    2010-06-21

    The bacterial nucleoid-associated protein Fis regulates diverse reactions by bending DNA and through DNA-dependent interactions with other control proteins and enzymes. In addition to dynamic nonspecific binding to DNA, Fis forms stable complexes with DNA segments that share little sequence conservation. Here we report the first crystal structures of Fis bound to high- and low-affinity 27-base-pair DNA sites. These 11 structures reveal that Fis selects targets primarily through indirect recognition mechanisms involving the shape of the minor groove and sequence-dependent induced fits over adjacent major groove interfaces. The DNA shows an overall curvature of {approx}65{sup o}, and the unprecedented close spacing between helix-turn-helix motifs present in the apodimer is accommodated by severe compression of the central minor groove. In silico DNA structure models show that only the roll, twist, and slide parameters are sufficient to reproduce the changes in minor groove widths and recreate the curved Fis-bound DNA structure. Models based on naked DNA structures suggest that Fis initially selects DNA targets with intrinsically narrow minor grooves using the separation between helix-turn-helix motifs in the Fis dimer as a ruler. Then Fis further compresses the minor groove and bends the DNA to generate the bound structure.

  15. MINORITY STRESS, POSITIVE IDENTITY DEVELOPMENT, AND DEPRESSIVE SYMPTOMS: IMPLICATIONS FOR RESILIENCE AMONG SEXUAL MINORITY MALE YOUTH

    2015-01-01

    Introduction Minority stress processes have been shown to have significant associations with negative mental health outcomes among sexual minority populations. Given that adversity may be experienced growing up as a sexual minority in heteronormative, if not heterosexist, environments, our research on resilience among sexual minority male youth proposes that positive identity development may buffer the effects of a range of minority stress processes. Methods An ethnically diverse sample of 200 sexual minority males ages 16–24 (mean age, 20.9 years) was recruited using mixed recruitment methods. We developed and tested two new measures: concealment stress during adolescence and sexual minority-related positive identity development. We then tested a path model that assessed the effects of minority stressors, positive identity development, and social support on major depressive symptoms. Results Experience of stigma was associated with internalized homophobia (β=.138, p<.05) and major depressive symptoms (β=1.076, OR=2.933, p<.001), and internalized homophobia partially mediated experience’s effects on major depression (β=.773, OR=2.167, p<.001). Concealment stress was associated with positive identity development (β=.155, p<.05) and internalized homophobia (β=.418, p<.001), and positive identity development partially mediated concealment stress’s effects on internalized homophobia (β=−.527, p<.001). Concealment stress demonstrated a direct effect on major depression (β=1.400, OR=4.056, p<.001), and indirect paths to social support through positive identity development. Conclusions With these results, we offer an exploratory model that empirically identifies significant paths among minority stress dimensions, positive identity development, and major depressive symptoms. This study helps further our understanding of minority stress, identity development, and resources of resilience among sexual minority male youth. PMID:26478901

    Satisfaction with care is important to cancer survivors' health outcomes. Satisfaction with care is not equal for all cancer survivors, and sexual minority (i.e., lesbian, gay, and bisexual) cancer survivors may experience poor satisfaction with care. Data were drawn from the 2010 LIVESTRONG national survey. The final sample included 207 sexual minority cancer survivors and 4,899 heterosexual cancer survivors. Satisfaction with care was compared by sexual orientation, and a Poisson regression model was computed to test the associations between sexual orientation and satisfaction with care, controlling for other relevant variables. Sexual minority cancer survivors had lower satisfaction with care than did heterosexual cancer survivors (B = -0.12, SE = 0.04, Wald χ(2) = 9.25, p< .002), even controlling for demographic and clinical variables associated with care. Sexual minorities experience poorer satisfaction with care compared to heterosexual cancer survivors. Satisfaction with care is especially relevant to cancer survivorship in light of the cancer-related health disparities reported among sexual minority cancer survivors.

  17. Atmospheric Solar Heating in Minor Absorption Bands

    NASA Technical Reports Server (NTRS)

    Chou, Ming-Dah

    1998-01-01

    Solar radiation is the primary source of energy driving atmospheric and oceanic circulations. Concerned with the huge computing time required for computing radiative transfer in weather and climate models, solar heating in minor absorption bands has often been neglected. The individual contributions of these minor bands to the atmospheric heating is small, but collectively they are not negligible. The solar heating in minor bands includes the absorption due to water vapor in the photosynthetically active radiation (PAR) spectral region from 14284/cm to 25000/cm, the ozone absorption and Rayleigh scattering in the near infrared, as well as the O2 and CO2 absorption in a number of weak bands. Detailed high spectral- and angular-resolution calculations show that the total effect of these minor absorption is to enhance the atmospheric solar heating by approximately 10%. Depending upon the strength of the absorption and the overlapping among gaseous absorption, different approaches are applied to parameterize these minor absorption. The parameterizations are accurate and require little extra time for computing radiative fluxes. They have been efficiently implemented in the various atmospheric models at NASA/Goddard Space Flight Center, including cloud ensemble, mesoscale, and climate models.

    Sexual minorities (e.g., lesbians, gay men, bisexual individuals) are at an increased risk for poorer mental and physical health outcomes than heterosexuals, and some of these health disparities relate to minority stressors such as discrimination. Yet, there is little research elucidating pathways that predict health or that promote resiliency among sexual minorities. Building on the minority stress model, the present study utilized relational cultural theory to situate sexual minority health within a relational framework. Specifically, the study tested mediators of the relationships between distal (i.e., discrimination, rejection, victimization) and proximal stressors (i.e., internalized homophobia, sexual orientation concealment) and psychological and physical distress for sexual minorities. Among 719 sexual minority adults, structural equation modeling analyses were used to test 4 models reflecting the mediating effects of shame, poorer relationships with a close peer and the lesbian/gay/bisexual/transgender (LGBT) community, and loneliness on the associations between minority stressors and psychological distress (i.e., depression and anxiety) and physical distress (i.e., distressing physical symptoms). As hypothesized, the associations between distal and proximal minority stressors and distress were mediated by shame, poorer relationships with a close peer and the LGBT community, and loneliness. Findings underscore the possible relational and interpersonal mechanisms by which sexual minority stressors lead to psychological and physical distress.

    Three basic studies, using spectrographic methods, have been used to establish the occurrence of minor elements in natural waters. One study, of oceanborne chemicals in principal rivers, has established a method for the quantitative analysis of many minor elements. Strontium, barium, lithium, rubidium, chromium, nickel, copper, lead, boron, titanium, molybdenum, manganese, and vanadium occur most frequently in measurable quantities. Reconnaissance of the strontium in surface waters of the United States, shows that surface waters in parts of northern and western Texas and southern New Mexico and Arizona are comparatively high in strontium. A study of minor elements in selected waters of California is continuing. Assessment of preliminary data on uranium and radium in waters is facilitated by grouping data for 10 geotectonic regions of the United States.

  10. Major surgical complications from minor urological procedures.

    PubMed Central

    Eke, N.

    2000-01-01

    Some urological procedures are regarded as minor or simple. As a result, these may be delegated to trainee surgeons to do. Occasionally nonmedical persons embark on some of the procedures such as male circumcision. Published serious complications from urological procedures considered minor or simple were identified from a Medline search (1966 through 1999) and reference lists of relevant publications. The operations regarded as minor were carried out by medical personnel of all grades as well as by nonmedical persons. The complications can be classified as mutilatory, infective, hemorrhagic, or obstructive. Although the mutilatory complications affect mainly procedures on the penis, infective and hemorrhagic complications affect almost all the procedures. Tumor implantation has occurred along needle biopsy tracts. Although many of the complications are not related to technique or competence, a plea is made for the awareness of their occurrence to encourage preventive strategies. Adequate training of surgical personnel remains essential worldwide. PMID:10976176

  11. Ethics in age estimation of unaccompanied minors.

    PubMed

    Thevissen, P W; Kvaal, S I; Willems, G

    2012-11-30

    Children absconding from countries of conflict and war are often not able to document their age. When an age is given, it is frequently untraceable or poorly documented and therefore questioned by immigration authorities. Consequently many countries perform age estimations on these children. Provision of ethical practice during the age estimation investigation of unaccompanied minors is considered from different angles: (1) The UN convention on children's rights, formulating specific rights, protection, support, healthcare and education for unaccompanied minors. (2) Since most age estimation investigations are based on medical examination, the four basic principles of biomedical ethics, namely autonomy, beneficence, non-malevolence, justice. (3) The use of medicine for non treatment purposes. (4) How age estimates with highest accuracy in age prediction can be obtained. Ethical practice in age estimation of unaccompanied minors is achieved when different but related aspects are searched, evaluated, weighted in importance and subsequently combined. However this is not always feasible and unanswered questions remain.

  12. Disclosure experiences of sexual minority college student victims of intimate partner violence.

    PubMed

    Sylaska, Kateryna M; Edwards, Katie M

    2015-06-01

    Although research on disclosure following intimate partner violence (IPV) victimization is burgeoning, sexual minority young adults' (lesbian, gay, bisexual, queer, questioning, etc.; LGBQ+) experiences have not received equal attention. The current study employed the minority stress framework to examine disclosure experiences of LGBQ+ college students across the United States reporting physical IPV victimization within their current relationship (n = 77). Participants completed measures assessing minority stress and IPV disclosure, and answered open-ended questions regarding the most and least helpful persons/responses to disclosure or reasons for non-disclosure. Results indicated that approximately one-third (35 %) of victims disclosed to at least one person, with friends being the most common recipients. Thematic analyses indicated that talking or listening to the victim was considered the most helpful response and not understanding the situation least helpful. Reasons for non-disclosure centered on themes of the victims' perception that the IPV was not a big deal. Quantitative findings regarding physical IPV disclosure indicated that non-disclosers experienced greater minority stress than disclosers. The current study suggests the presence of differences between sexual minority (i.e., LGBQ +persons) and non-sexual minority persons, as well as between LGBQ+ young adults/college students and older adults and presents a theoretical structure (i.e., minority stress framework) through which these differences may be understood.

  13. The role of personality in predicting drug and alcohol use among sexual minorities.

    Livingston, Nicholas A; Oost, Kathryn M; Heck, Nicholas C; Cochran, Bryan N

    2015-06-01

    Research consistently demonstrates that sexual minority status is associated with increased risk of problematic substance use. Existing literature in this area has focused on group-specific minority stress factors (e.g., victimization and internalized heterosexism). However, no known research has tested the incremental validity of personality traits as predictors of substance use beyond identified group-specific risk factors. A sample of 704 sexual minority adults was recruited nationally from lesbian, gay, bisexual, transgender, queer, and questioning community organizations and social networking Web sites and asked to complete an online survey containing measures of personality, sexual minority stress, and substance use. Hierarchical regression models were constructed to test the incremental predictive validity of five-factor model personality traits over and above known sexual minority risk factors. Consistent with hypotheses, extraversion and conscientiousness were associated with drug and alcohol use after accounting for minority stress factors, and all factors except agreeableness were associated with substance use at the bivariate level of analysis. Future research should seek to better understand the role of normal personality structures and processes conferring risk for substance use among sexual minorities. (PsycINFO Database Record

    majorant, which is then used to find a complete description of the concave majorant of a walk of infinite length. In the case where subsets of increments may have the same arithmetic mean (the more general case mentioned above), we investigate three nested compositions that naturally arise from our construction of the concave majorant. This chapter is based on [4], which was co-written with Jim Pitman. In Chapter 3, we study the Lipschitz minorant of a Levy process. For alpha > 0, the alpha-Lipschitz minorant of a function f : R→R is the greatest function m : R→R such that m ≤ f and | m(s) - m(t)| ≤ alpha |s - t| for all s, t ∈ R should such a function exist. If X = Xtt∈ R is a real-valued Levy process that is not pure linear drift with slope +/-alpha, then the sample paths of X have an alpha-Lipschitz minorant almost surely if and only if | E [X1]| < alpha. Denoting the minorant by M, we investigate properties of the random closed set Z := {t ∈ R : Mt = {Xt ∧ Xt-}, which, since it is regenerative and stationary, has the distribution of the closed range of some subordinator "made stationary" in a suitable sense. We give conditions for the contact set Z to be countable or to have zero Lebesgue measure, and we obtain formulas that characterize the Levy measure of the associated subordinator. We study the limit of Z as alpha → infinity and find for the so-called abrupt Levy processes introduced by Vigon that this limit is the set of local infima of X. When X is a Brownian motion with drift beta such that |beta| < alpha, we calculate explicitly the densities of various random variables related to the minorant. This chapter is based on [2], which was co-written with Steven N. Evans. Finally, in Chapter 4 we study the structure of the shocks for the inviscid Burgers equation in dimension 1 when the initial velocity is given by Levy noise, or equivalently when the initial potential is a two-sided Levy process This shock structure turns out to give rise to a

    We examine the possibility that a certain class of neutrino mass matrices, namely, those with two independent vanishing minors in the flavor basis, regardless of being invertible or not, is sufficient to describe current data. We compute generic formulas for the ratios of the neutrino masses and for the Majorana phases. We find that seven textures with two vanishing minors can accommodate the experimental data. We present an estimate of the mass matrix for these patterns. All of the possible textures can be dynamically generated through the seesaw mechanism augmented with a discrete Abelian symmetry.

    We aspired to teach minority middle school students to solder. We found that important variables affecting our ability to do so included: student-to-teacher ratio, venue of instruction, relationships with community partners, and understanding of the structure of the student's worldview. Once the effects of these variables had been understood, we found the students readily learned to solder. We now want to see whether the acquisition of the skill of soldering leads the students to be more interested in technical careers and in going to college. Supported by an APS Outreach Mini-grant.

    1999-11-01

    A sialolith from a minor salivary gland of the mucosa of the upper lip was studied morphologically and analytically. Under stereoscopic microscopic visualisation, no core or any concentric laminar structure was found in the sialolith and it had a transparent glassy appearance. Scanning electron microscopy revealed differences between the internal structure of the sialolith and its external structure. No microbes were observed but some mineralized inclusion bodies were seen. X-ray diffraction indicated the absence of inorganic crystals in the sialolith, while energy dispersive x-ray microanalysis revealed a high content of S followed by Ca, Si and Na and little and scarce P on the fracture surface, with S, Na, Ca and P being distributed throughout the external coating of the sialolith. The results suggest that the sialolith was young and consisted of a crystalloid body with an incipient coating undergoing calcification.

  4. NMR studies of DNA oligomers and their interactions with minor groove binding ligands

    SciTech Connect

    Fagan, Patricia A.

    1996-05-01

    The cationic peptide ligands distamycin and netropsin bind noncovalently to the minor groove of DNA. The binding site, orientation, stoichiometry, and qualitative affinity of distamycin binding to several short DNA oligomers were investigated by NMR spectroscopy. The oligomers studied contain A,T-rich or I,C-rich binding sites, where I = 2-desaminodeoxyguanosine. I•C base pairs are functional analogs of A•T base pairs in the minor groove. The different behaviors exhibited by distamycin and netropsin binding to various DNA sequences suggested that these ligands are sensitive probes of DNA structure. For sites of five or more base pairs, distamycin can form 1:1 or 2:1 ligand:DNA complexes. Cooperativity in distamycin binding is low in sites such as AAAAA which has narrow minor grooves, and is higher in sites with wider minor grooves such as ATATAT. The distamycin binding and base pair opening lifetimes of I,C-containing DNA oligomers suggest that the I,C minor groove is structurally different from the A,T minor groove. Molecules which direct chemistry to a specific DNA sequence could be used as antiviral compounds, diagnostic probes, or molecular biology tools. The author studied two ligands in which reactive groups were tethered to a distamycin to increase the sequence specificity of the reactive agent.

  5. Macro-Level Approaches to HIV Prevention Among Ethnic Minority Youth

    Prado, Guillermo; Lightfoot, Marguerita; Brown, C. Hendricks

    2013-01-01

    The HIV epidemic continues to disproportionately affect ethnic minority youth. These disconcerting health disparities indicate that although existing HIV preventive strategies for ethnic minority youth have been efficacious, they have not significantly reduced the impact of the epidemic in this population. Macro-level interventions, such as structural or policy interventions, have the potential to impact the HIV epidemic at a population level, and thus reduce the HIV health disparities that exist among ethnic minority youth and other segments of the U.S. population. This article calls for a paradigm shift to develop, evaluate, and disseminate interventions that target upstream/macro-level factors or that, at a minimum, integrate both a macro and individual level perspective. The article also discusses the challenges in developing and evaluating such interventions. Psychologists and other behavioral scientists can play a critical role in reducing the impact of HIV on ethnic minority youth by integrating macro-level approaches to future HIV prevention strategies.

    2003-09-01

    The shortage of faculty in dental education is well documented, but the data also show a shortage of minorities in postgraduate programs, which develop future faculty. In the last ten years, ADEA's effort to address minority issues in dental education has made some progress. In addition, examples of pipelines for minority faculty development that have shown some success include: a partnership between Harlem Hospital and Columbia University School of Dentistry and Oral Surgery in which the school dedicates one position in its postgraduate training programs to an individual participating in the Harlem Hospital General Practice Residency program; a partnership between the National Dental Association Foundation and Colgate-Palmolive Company, which provides scholarships for advanced dental education study; and the Bronx Lebanon Hospital Center Department of Dentistry, which enrolls underrepresented minorities in its General Practice Residency Program, a new Pediatric Dentistry Residency Program, and a unique program providing hands-on experience in HIV/AIDS health care policy and AIDS development management. Critical elements in the relative success of these programs are environment, selection criteria, mentoring, networking, and finance. The true measure of the outcomes is still to be seen.

  11. [Mental health problems in ethnic minority groups].

    PubMed

    Kucharska, Justyna

    2012-01-01

    The aim of this paper is to provide an insight into the specificity of mental health issues as experienced by ethnic minority groups' representatives. A substantial body of evidence clearly indicates the differences in incidence of psychosis, affective disorders and suicidal tendencies in members of minority groups compared to the rest of the population. Relevant statistical data will be presented and examined from both a biological and socio-cultural point of view. Hoffman's Social Deafferentation Hypothesis will be introduced as a possible explanation of high incidence of psychotic disorders in immigrants. Subsequently, socio-cultural factors will receive attention. Acculturation and identity issues will be taken into account with regards to the data suggesting that these are second generation immigrants that suffer from mental health disorders most. The fact of being discriminated against and being exposed to negative social messages regarding one's group of reference will also be taken into consideration. Moreover, ethnic minorities will be compared on this dimension with other groups discriminated against, such as women and sexual minorities.

  18. Language choice in a minority school

    NASA Astrophysics Data System (ADS)

    Byram, M. S.

    1985-12-01

    This article arises from fieldwork in a school of the German minority in South Jutland, Denmark. The minority exists as a result of frontier changes between Germany and Denmark, most recently in 1920. A referendum held in that year as a result of the Treaty of Versailles left a cultural and linguistic minority which, by today, has its own school system, politial party and cultural rights. The research was carried out using qualitative, ethnographic methods and the article focuses on one aspect, namely the issue of language use by bilingual pupils in one of the minority's schools. Pupils' choice of Danish or German in different situations within and outside schools was analyzed through the use of language diaries, informal interviews, and participant observation. The diary entries are analyzed and commented on in the light of interviews and observations. Pupils' awareness of their language use is not static but becomes dynamic as a consequence of being involved in research. The implications of this for educational policy are considered in the context of current developments in language education in British schools.

  19. Quantum annealing correction with minor embedding

    NASA Astrophysics Data System (ADS)

    Vinci, Walter; Albash, Tameem; Paz-Silva, Gerardo; Hen, Itay; Lidar, Daniel A.

    2015-10-01

    Quantum annealing provides a promising route for the development of quantum optimization devices, but the usefulness of such devices will be limited in part by the range of implementable problems as dictated by hardware constraints. To overcome constraints imposed by restricted connectivity between qubits, a larger set of interactions can be approximated using minor embedding techniques whereby several physical qubits are used to represent a single logical qubit. However, minor embedding introduces new types of errors due to its approximate nature. We introduce and study quantum annealing correction schemes designed to improve the performance of quantum annealers in conjunction with minor embedding, thus leading to a hybrid scheme defined over an encoded graph. We argue that this scheme can be efficiently decoded using an energy minimization technique provided the density of errors does not exceed the per-site percolation threshold of the encoded graph. We test the hybrid scheme using a D-Wave Two processor on problems for which the encoded graph is a two-level grid and the Ising model is known to be NP-hard. The problems we consider are frustrated Ising model problem instances with "planted" (a priori known) solutions. Applied in conjunction with optimized energy penalties and decoding techniques, we find that this approach enables the quantum annealer to solve minor embedded instances with significantly higher success probability than it would without error correction. Our work demonstrates that quantum annealing correction can and should be used to improve the robustness of quantum annealing not only for natively embeddable problems but also when minor embedding is used to extend the connectivity of physical devices.

  20. A European phylogeography of Rhinanthus minor compared to Rhinanthus angustifolius: unexpected splits and signs of hybridization

    PubMed Central

    Vrancken, Jérôme; Brochmann, Christian; Wesselingh, Renate A

    2012-01-01

    Rhinanthus minor and Rhinanthus angustifolius (Orobanchaceae) are annual hemiparasites, which occur sympatrically in Europe and are known to hybridize. We studied chloroplast and nuclear (amplified fragment length polymorphism [AFLP]) diversity in R. minor and compared genetic structuring in this species with R. angustifolius by analyzing the AFLP data for both species simultaneously. The AFLP data revealed that populations in Italy, Greece, and southeast Russia initially identified as R. minor were so distant from the other R. minor populations that they probably belong to another, yet unidentified taxon, and we refer to them as Rhinanthus sp. R. minor s.s. showed a clear geographic genetic structure in both the chloroplast DNA (cpDNA) and nuclear genome. The simultaneous analysis of both species shed new light on the previously published findings for R. angustifolius, because some populations now turned out to belong to R. minor. The admixture analysis revealed very few individuals of mixed R. minor–R.angustifolius ancestry in the natural populations in the west of Europe, while admixture levels were higher in the east. The combined haplotype network showed that haplotype H1 was shared among all species and is likely to be ancestral. H2 was more abundant in R. angustifolius and H3 in R. minor, and the latter probably arose from H1 in this species in the east of Europe. The occurrence of H3 in R. angustifolius may be explained by introgression from R. minor, but without interspecific admixture, these are likely to have been old hybridization events. Our study underlines the importance of including related species in phylogeographic studies. PMID:22957160

  1. The impact of civil union legislation on minority stress, depression, and hazardous drinking in a diverse sample of sexual-minority women: A quasi-natural experiment

    PubMed Central

    Everett, Bethany G.; Hatzenbuehler, Mark L.; Hughes, Tonda L.

    2017-01-01

    Rationale A small but growing body of research documents associations between structural forms of stigma (e.g., same-sex marriage bans) and sexual minority health. These studies, however, have focused on a limited number of outcomes and have not examined whether sociodemographic characteristics, such as race/ethnicity and education, influence the relationship between policy change and health among sexual minorities. Objective To determine the effect of civil union legalization on sexual minority women’s perceived discrimination, stigma consciousness, depressive symptoms, and four indicators of hazardous drinking (heavy episodic drinking, intoxication, alcohol dependence symptoms, adverse drinking consequences) and to evaluate whether such effects are moderated by race/ethnicity or education. Methods During the third wave of data collection in the Chicago Health and Life Experiences of Women study (N=517), Illinois passed the Religious Freedom Protection and Civil Union Act, legalizing civil unions in Illinois and resulting in a quasi-natural experiment wherein some participants were interviewed before and some after the new legislation. Generalized linear models and interactions were used to test the effects of the new legislation on stigma consciousness, perceived discrimination, depression, and hazardous drinking indicators. Interactions were used to assess whether the effects of policy change were moderated by race/ethnicity or education. Results Civil union legislation was associated with lower levels of stigma consciousness, perceived discrimination, depressive symptoms, and one indicator of hazardous drinking (adverse drinking consequences) for all sexual minority women. For several other outcomes, the benefits of this supportive social policy were largely concentrated among racial/ethnic minority women and women with lower levels of education. Conclusions Results suggest that policies supportive of the civil rights of sexual minorities improve the health

  2. HUBBLE SPACE TELESCOPE View of the Heart of Ursa Minor

    NASA Astrophysics Data System (ADS)

    Battinelli, Paolo; Demers, Serge

    1999-04-01

    Hubble Space Telescope F606W observations to 26th magnitude are used to investigate the stellar distribution in the center of the Ursa Minor dwarf spheroidal galaxy. The central surface density is found to be low, less than 700 stars arcmin^-2, with no sign of a pronounced cusp. The maximum of the surface density is not found at our adopted center but in a ringlike structure some 13" from it. We identify this feature with the subclustering identified by Olszewski & Aaronson, who believed that it was off-center. The currently accepted King's structural parameters, r_c and r_t, of Ursa Minor are found to be unsuitable to represent the stellar surface density near the center. Our star counts are used to obtain a lower limit of the central stellar density without the use of the velocity dispersion. We find a lower limit of 1.7+/-1.1 M_solar pc^-3 from stars that were counted. By extrapolating the mass function to lower masses, we estimate that the true density could increase be a factor of 7.

  3. By whose standard? The affective implications of ethnic minorities' comparisons to ethnic minority and majority referents

    PubMed Central

    LEACH, COLIN WAYNE; SMITH, HEATHER J.

    2007-01-01

    In a ‘diary’ study, we examined the frequency and affective implications of 34 ethnic minority students' comparisons to other ethnic minorities or to members of a high-status ethnic majority (i.e., European-Americans). Participants made more frequent comparisons to ethnic majority than ethnic minority referents, although neither type of comparison tended to be perceived in terms of group membership (see also Smith & Leach, 2004). Comparisons to ethnic majority referents did not alter participants' positive affect even where they suggested poor future prospects in status-relevant domains. In contrast, comparisons to fellow ethnic minorities led to increased positive affect when they suggested a future prospect of improvement. We discuss the conceptual and practical implications of social comparison in the context of group status. PMID:17330149

    Background Sexual minorities are more likely than heterosexuals to engage in unhealthy eating behaviors. Purpose To examine sexual minority stressors and internalizing symptoms as predictors of unhealthy eating behaviors among sexual minority youth. Methods We used longitudinal data from 1461 sexual minority youth in the Growing Up Today Study, across ages 14-28 years. We hypothesized that sexual minority stressors would predict unhealthy eating behaviors, in part due to internalizing symptoms. Linear regression models fit via generalized estimating equations were stratified by gender and sexual orientation. Results Significant positive and inverse associations between stressors and eating behaviors were detected among females and males, with more significant associations among females. Associations were attenuated by up to 71% for females and 12% for males when internalizing symptoms were added to the models. Conclusions Sexual minority stressors predicted unhealthy eating behaviors overall and more so for some sexual orientation and gender groups; associations were partially explained by internalizing symptoms. The conceptual model appears to best describe the experiences of bisexual females. Findings have clinical implications for adolescent health. PMID:26156678

  5. Minor Planet Center: data processing challenges

    NASA Astrophysics Data System (ADS)

    Rudenko, Michael

    2016-01-01

    The Minor Planet Center receives up to several million astrometric observations of minor planets and comets each month. Given the volume of observations, the sheer number of known objects against which to possibly match, the shortness of the time interval over which each object was likely observed, and the uncertainties in the positions, and occasionally possible errors in times, reported, a number of data processing challenges present themselves. These include: Identifying observations of objects reported as new with already known objects; linking together sets of observations from different nights which may belong to the same object; determining if a set of observations has been assigned to the wrong object; determining if an object with a very short arc is possibly a Near-Earth object; prioritizing newly discovered objects in order of need of follow up; and, efficiently matching one or more observations with known objects.

  6. Counseling utilization by ethnic minority college students.

    Kearney, Lisa K; Draper, Matthew; Barón, Augustine

    2005-08-01

    Although multicultural awareness in counseling has risen substantially in the last decade, little research has examined counseling utilization and outcomes for ethnic minorities on university campuses. A sample of 1,166 African American, Asian American, Caucasian, and Latino help-seeking university students from over 40 universities nationwide filled out the Outcome Questionnaire 45 (OQ45) at the first and last therapy sessions. Caucasian students attended significantly more sessions than all other groups. Greatest distress was found at intake in Asian American students, followed by Latino, African American, and Caucasian students. All groups appeared to benefit from therapy, as noted by a decrease in symptomatology, but none of the groups met the criteria for clinically significant change for the OQ45. Implications for therapists working with minority clients are discussed.

    PubMed

    Hathaway, W E; Assmus, S L; Montgomery, R R; Dubansky, A S

    1979-01-01

    Five commercially available activated partial thromboplastin time (APTT) test systems were compared with the kaolin partial thromboplastin time (KPTT) method to determine sensitivity in detecting minor coagulation defects. All reagent systems detected severe factor VIII-, IX-, and XI-deficient hemophilia. Homozygous states of factor XII deficiency, Fletcher factor deficiency, and high-molecular-weight kininogen deficiency (Fitzgerald trait) also showed abnormally long APTTs by all systems. Of 19 samples from patients with deficiencies of factors XII, VIII, IX, XI, and II ranging from 2.5 to 52%, eight had deficiencies that were not detected by reagent A (ellagic acid); two, by reagent B (ellagic acid); two, by reagent C (kaolin); one, by reagent D (silica); one, by the KPTT method. All deficiencies were detected by reagent E (celite). Heparin effect on plasma was less well detected by reagent A (ellagic acid) than with the other test systems. APTT test systems can vary greatly in their abilities to detect minor coagulation abnormalities.

  8. Perceived sibling relationships of sexual minority youth.

    PubMed

    Toomey, Russell B; Richardson, Rhonda A

    2009-01-01

    The purpose of this study was to examine the relationships of sexual minority youth and their siblings. The participants were 56 lesbian, gay, bisexual, or transgender individuals ranging in age from 18 to 24 years, who reported information about a total of 107 siblings. Respondents completed a demographic data questionnaire as well as adapted versions of the Sibling Closeness Scale (SCS) and the Sibling Approval of Sexual Behavior Scale (SASBS) to describe their relationship with each of their siblings. Analyses examined birth order and gender in relation to outness to siblings as well as sibling closeness and approval. Results provide information about disclosure of LGBT status to siblings, elements of closeness and acceptance in sibling relationships of sexual minority youth, and the significance of gender and birth order in these sibling relationships.

  9. Minor congenital anomalies and ataxic cerebral palsy.

    Miller, G

    1989-01-01

    The incidence of minor congenital anomalies was examined in 36 patients with ataxic cerebral palsy, in unaffected family members, and in 100 unrelated control subjects. None of the control subjects or family members had more than four anomalies, and 25 of 36 (69%) of the patients had more than four. The distribution of anomalies differed considerably, with 60% of the index cases having seven or more, and 94% of the controls having three or less. The number occurring in the patients was significantly more than in their relatives. Of the 25 patients with more than four anomalies, 16 (64%) had undergone potentially adverse perinatal or early postnatal events. Thus minor congenital anomalies were considerably more frequent in those with ataxic cerebral palsy than in related or unrelated control subjects. These anomalies may be markers of early prenatal factors that contributed to the adverse outcome either directly or by predisposing to perinatal difficulties. PMID:2751330

    Fifty consecutive patients underwent minor elective gynecologic surgery. Most of them were from the low socioeconomic class. Twenty-five patients had their pubic, vulval and perineal hair shaved as part of the preoperative preparation. All patients underwent the same routine perineal, vulval and vaginal swabbing in the operating room. All patients were then examined for postoperative complications. Only two women (who were shaved) complained of mild lower abdominal pain 48 hours after operation, but neither had any clinical evidence of genital or urinary infection. Their symptoms disappeared with the use of analgesics. Even in developing countries where patients with poor personal hygiene are common, preoperative vulval, pubic and perineal hair shaving prior to minor gynecologic surgery is unnecessary. We suggest that this procedure should be discontinued.

    The focus of this investigation was to identify issues central to increasing the involvement of small minority businesses (MBs) in federal or prime contracts with the Department of Energy (DOE), as a foundation for designing a program to assist buyers of contracted goods and services. The approach to determining issues involved interviewing the owners of 15 MBs, representing a range of businesses, and buyers and purchasing officers from three large DOE prime contractors. The interviewees identified issues related to positive working relationships and rated a predetermined set of 27 potential MB-DOE problems regarding their existence and criticalness. The issues identified by MBs were of two broad types. The predominant issues and barriers were associated with their being small businesses. Secondary issues reflected the disadvantaged status of the business (woman and/or minority-owned).

    Diversity is crucial to the future of nursing. And fortunately, a shift in the composition of the nursing workforce so that it more accurately mirrors the composition of America's patient population is already taking place. However, this emerging multiculturalism brings an important issue to the forefront-the leadership tier in healthcare organizations must also reflect the ethnic and cultural changes taking place. Movement in this direction makes prominent the importance of the mentor role in the life of the minority nurse seeking a leadership career path. Acknowledging the present demographics of the profession, it is most unlikely that the mentor and mentee will be a cultural or ethnic match. The good news is that this should not be viewed as an automatic barrier. This article describes the 5 Cs of mentoring a minority nurse professional, that is, candor, compromise, confidence, complexity, and champion-the specific competencies that promote a mentor-mentee relationship focused on career success.

  13. Meeting the needs of minority ethnic communities.

    1996-01-01

    Concentrating on exotica and cultural differences merely allows commissioners and providers to ignore general health needs and blame the communities themselves when they receive poor quality services. We now have to move forward if we are to achieve an improvement in their health care. We are not talking of an insignificant minority, but nearly one in 10 of all children. Clearly real differences in health needs do exist, for example haemoglobinopathy associated illness; these need to be addressed and adequate provision made. It is in meeting the general needs of minority ethnic children that we face the greatest challenge. These are no different to those of the white ethnic majority. However, meeting them may require different--sometimes radically different--response strategies on behalf of both purchasers and providers of health care to children, supported by appropriate training, audit, and research.

    Our hospitals are suffering from an increasing run of "minor emergency cases". Those are simple medical or surgical ailments that could be taken care of by a general practitioner's office in a competent and cost efficient way. Because of the ever growing problem of a shortage of general practitioners, those patients are directly going to the emergency room of our hospitals, where they are usually seen by a young and yet unexperienced doctor, who is ordering an expensive battery of tests even for minor troubles of his or her wellbeing. It was shown that emergency room crowding has a negative impact on the quality of patient care. The establishment of an office run by a general practitioner within the hospital emergency room may result in a certain relief of the situation.

    In Europe and particularly in Bulgaria, Roma represent the largest low-status minority group that is subjected to marked public intolerance and discrimination. This study examined links among Roma (N = 207) and Bulgarian (N = 399) adolescents' ethnic, familial, and religious identities as salient identity aspects for their psychological wellbeing. Results indicated that, as expected, Roma youth reported lower levels of wellbeing than Bulgarian youth. The latter revealed a weaker religious identity than Roma youth, whereas no ethnic group differences emerged regarding Bulgarian or familial identity. Furthermore, we observed that collective identity was higher in older participants of both groups. Finally, a multigroup analysis using structural equation modeling showed that collective identity was a positive predictor of wellbeing for both Roma and Bulgarian adolescents. Findings demonstrated differences in salience as well as structural communalities regarding ways in which collective identity affects wellbeing of youth from two ethnically diverse communities.

    A simulated skin preparation is described which is made by bonding siliconized rubber to a latex foam base. This composite material, which simulates both the dermis/epidermis and subcutaneous fat, provides a realistic model which can be used to teach excision of skin lesions and a variety of suturing methods. We believe that this simulator is of value not only for surgeons in-training but also will allow general practitioners to improve their technical skills in performing minor surgical procedures.

    Minor mode is known to elicit stronger emotional responses than major mode in the brain. The present work focused on the minor scales and natural and harmonic minor scales were compared in automatic brain responses in an oddball paradigm. The standard stimulus was either the natural or harmonic minor scale, and a deviant stimulus lacked one scale tone of the corresponding complete minor scale. The brain responded to omission of every tone but omission of the tone B flat in the natural minor experiment elicited larger response than that of the other tones. In particular, the response was significantly larger than that to omission of B in the harmonic minor experiment. This result suggested that the brain felt the natural minor scale to be actually more natural than the harmonic minor scale.

  2. Toward a Model of Social Influence that Explains Minority Student Integration into the Scientific Community.

    2011-02-01

    Students from several ethnic minority groups are underrepresented in the sciences, such that minority students more frequently drop out of the scientific career path than non-minority students. Viewed from a perspective of social influence, this pattern suggests that minority students do not integrate into the scientific community at the same rate as non-minority students. Kelman (1958, 2006) describes a tripartite integration model of social influence (TIMSI) by which a person orients to a social system. To test if this model predicts integration into the scientific community, we conducted analyses of data from a national panel of minority science students. A structural equation model framework showed that self-efficacy (operationalized consistent with Kelman's 'rule-orientation') predicted student intentions to pursue a scientific career. However, when identification as a scientist and internalization of values are added to the model, self-efficacy becomes a poorer predictor of intention. Additional mediation analyses support the conclusion that while having scientific self-efficacy is important, identifying with and endorsing the values of the social system reflect a deeper integration and more durable motivation to persist as a scientist.

    Aim: Emerging racial/ethnic disparities in tobacco use behaviors and resulting long-term health outcomes highlight the importance of developing culturally tailored/targeted tobacco prevention and cessation interventions. This manuscript describes the efficacy and the components of prevention and cessation interventions developed for minority adolescents. Methods: Thirteen studies focused on culturally tailoring and targeting tobacco prevention/cessation interventions were selected and information on intervention design (type, number of sessions), setting (school or community), theoretical constructs, culture-specific components (surface/deep structures), and treatment outcomes were extracted. Results: Of the 13 studies, 5 focused on prevention, 4 on cessation, and 4 combined prevention and cessation, and most of the studies were primarily school-based, while a few used community locations. Although diverse minority groups were targeted, a majority of the studies (n = 6) worked with Hispanic adolescents. The most common theoretical construct examined was the Social Influence Model (n = 5). The overall findings indicated that culturally tailoring cessation interventions did not appear to improve tobacco quit rates among minority adolescents, but culturally tailored prevention interventions appeared to produce lower tobacco initiation rates among minority adolescents than control conditions. Conclusions: The results of review suggest that there is a critical need to develop better interventions to reduce tobacco use among minority adolescents and that developing a better understanding of cultural issues related to both cessation and initiation of tobacco use among minority populations is a key component of this endeavor.

    Sexual minorities have higher rates of depression and anxiety than their heterosexual counterparts. This elevated risk of psychological distress has generally been hypothesized to be a result of the effects of discrimination including internalized negative beliefs about sexual minorities. However, little research has examined the role of various types of coping in mediating between internalized homophobia and mental health. We tested the direct relationship between internalized homophobia and psychological distress and evaluated general and sexual minority-specific coping strategies as potential mediators using structural equation modeling. Data are from a national sample of 1,099 young adult sexual minority women who were on average 20.86 (SD= 2.12) years old, participating in a study on mental health and substance use. The model demonstrated acceptable fit, χ(2) (83) = 402.9, p <.001, CFI=.94, TLI=.92, SRMR= .07, and RMSEA=.06, accounting for 73% of variance in psychological distress. Greater use of maladaptive coping and less use of sexual minority-specific coping were associated with higher psychological distress. Although maladaptive coping mediated the relationship between internalized homophobia and psychological distress, sexual minority-specific coping did not. Our findings support previous studies that have demonstrated the impact of internalized homophobia on psychological distress as well as the role of coping as a protective/risk factor in this relationship.

    Sexual minority youth (youth who are attracted to the same sex or endorse a gay/lesbian/bisexual identity) report significantly higher rates of depression and suicidality than heterosexual youth. The minority stress hypothesis contends that the stigma and discrimination experienced by sexual minority youth create a hostile social environment that can lead to chronic stress and mental health problems. The present study used longitudinal mediation models to directly test sexual minority-specific victimization as a potential explanatory mechanism of the mental health disparities of sexual minority youth. One hundred ninety-seven adolescents (14-19 years old; 70 % female; 29 % sexual minority) completed measures of sexual minority-specific victimization, depressive symptoms, and suicidality at two time points 6 months apart. Compared to heterosexual youth, sexual minority youth reported higher levels of sexual minority-specific victimization, depressive symptoms, and suicidality. Sexual minority-specific victimization significantly mediated the effect of sexual minority status on depressive symptoms and suicidality. The results support the minority stress hypothesis that targeted harassment and victimization are partly responsible for the higher levels of depressive symptoms and suicidality found in sexual minority youth. This research lends support to public policy initiatives that reduce bullying and hate crimes because reducing victimization can have a significant impact on the health and well-being of sexual minority youth.

    The paper builds upon an earlier statistical analysis of financial time series with Shannon information entropy, published in [L. Molgedey, W. Ebeling, Local order, entropy and predictability of financial time series, European Physical Journal B-Condensed Matter and Complex Systems 15/4 (2000) 733-737]. A novel generic procedure is proposed for making multistep-ahead predictions of time series by building a statistical model of entropy. The approach is first demonstrated on the chaotic Mackey-Glass time series and later applied to Japanese Yen/US dollar intraday currency data. The paper also reinterprets Minority Games [E. Moro, The minority game: An introductory guide, Advances in Condensed Matter and Statistical Physics (2004)] within the context of physical entropy, and uses models derived from minority game theory as a tool for measuring the entropy of a model in response to time series. This entropy conditional upon a model is subsequently used in place of information-theoretic entropy in the proposed multistep prediction algorithm.

    The earth is warming, and it is warming quickly. Epidemiological studies have demonstrated that global warming is correlated with the frequency of pollen-induced respiratory allergy and allergic diseases. There is a body of evidence suggesting that the prevalence of allergic diseases induced by pollens is increasing in developed countries, a trend that is also evident in the Mediterranean area. Because of its mild winters and sunny days with dry summers, the Mediterranean area is different from the areas of central and northern Europe. Classical examples of allergenic pollen-producing plants of the Mediterranean climate include Parietaria, Olea and Cupressaceae. Asia Minor is a Mediterranean region that connects Asia and Europe, and it includes considerable coastal areas. Gramineae pollens are the major cause of seasonal allergic rhinitis in Asia Minor, affecting 1.3-6.4 % of the population, in accordance with other European regions. This article emphasizes the importance of global climate change and anticipated increases in the prevalence and severity of allergic disease in Asia Minor, mediated through worsening air pollution and altered local and regional pollen production, from an otolaryngologic perspective.

    With more and more applications appearing and the technology developing in the Internet, only relying on terminal system can not satisfy the complicated demand of QoS network. Router mechanisms must be participated into protecting responsive flows from the non-responsive. Routers mainly use active queue management mechanism (AQM) to avoid congestion. In the point of interaction between the routers, the paper applies minority game to describe the interaction of the users and observes the affection on the length of average queue. The parameters α, β of ARED being hard to confirm, adaptive RED based on minority game can depict the interactions of main body and amend the parameter α, β of ARED to the best. Adaptive RED based on minority game optimizes ARED and realizes the smoothness of average queue length. At the same time, this paper extends the network simulator plat - NS by adding new elements. Simulation has been implemented and the results show that new algorithm can reach the anticipative objects.

    Background Available data suggest that childhood cancer survivors (CCSs) are comparable to the general population on many lifestyle parameters. However, little is known about minority CCSs. This cross-sectional study describes and compares the body mass index (BMI) and health behaviors of African-American, Hispanic and White survivors to each other and to non-cancer controls. Methods Participants included 452 adult CCS (150 African-American, 152 Hispanic, 150 white) recruited through four childhood cancer treating institutions and 375 ethnically-matched non-cancer controls (125 in each racial/ethnic group) recruited via targeted digit dial. All participants completed a 2-hour in-person interview. Results Survivors and non-cancer controls reported similar health behaviors. Within survivors, smoking and physical activity were similar across racial/ethnic groups. African-American and Hispanic survivors reported lower daily alcohol use than whites, but consumed unhealthy diets and were more likely to be obese. Conclusions This unique study highlights that many minority CCSs exhibit lifestyle profiles that contribute to increased risk for chronic diseases and late effects. Recommendations for behavior changes must consider the social and cultural context in which minority survivors may live. PMID:25564774

    Over at least the last twenty years, the American Dental Education Association (ADEA) has given attention and priority to increasing the number of underrepresented minority (URM) dental school applicants, enrollees, and faculty members and to meeting the challenges of achieving diversity in the oral health workforce of the future as racial and ethnic minorities continue to grow and are expected to comprise more than 50 percent of the U.S. population by the middle of the twenty-first century. Dental schools have the responsibility of preparing dentists to provide oral health care for the nation's population. This includes creating a workforce of adequate size and racial/ethnic composition. As part of ADEA's priorities to improve the recruitment, retention, and development of URMs in the dental profession, with funding from the W.K. Kellogg Foundation, ADEA launched the Minority Dental Faculty Development Program in 2004. The intent of the program is to foster academic partnerships, mentoring, and institutional commitment and leadership designed to increase the number of URM individuals interested in and prepared for careers in academic dentistry.

    The postembryonic development and caste differentiation patterns of lower termites have been described multiple times in a variety of different species. However, most of these studies focused on gross ontogeny, without carefully describing the maturation of any particular organ or organ system. The few studies that have attempted to correlate caste development and organ differentiation have produced somewhat inconsistent results, especially in the area of eye formation. Therefore, in order to help further elucidate the relationship between eye formation and postembryonic differentiation in lower termites, we studied eye development in the termite, Incisitermes minor (Hagen). Eye formation in I. minor began in the earliest larvae, with only an eye primordium. However, in all later larval stages, characteristic eye structures were observed and were shown to progressively differentiate through larval and nymphal stages. Curiously, pigmentation began with three to eight groups of cells in early larvae and the number of these pigmented groups increased along the developmental time course. Ultimately, a uniformly pigmented eye area was formed by the early nymphal stage. The overall eye area also gradually increased along with normal caste development, but the characteristic lenses seen in a prototypical insect compound eye did not completely form until after the final nymphal stage. Electrophysiological measurements provided clear evidence that eyes were indeed functional at all stages of development where pigment was present. Based upon this data, the eye development pattern in I. minor appeared to follow a divergent pathway from holometabolous insects and an intermediate pathway between typical hemimetabolous eye development and the heterochronic shift observed in other termite species.

    This paper reports a study of the function and composition of social support networks among diverse lesbian, gay and bisexual (LGB) men and women (n = 396) in comparison to their heterosexual peers (n = 128). Data were collected using a structured social support network matrix in a community sample recruited in New York City. Our findings show that gay and bisexual men may rely on “chosen families” within LGBT communities more so than lesbian and bisexual women. Both heterosexuals and LGBs relied less on family and more on other people (e.g., friends, co-workers) for everyday social support (e.g., recreational and social activities, talking about problems). Providers of everyday social support were most often of the same sexual orientation and race/ethnicity as participants. In seeking major support (e.g., borrowing large sums of money), heterosexual men and women along with lesbian and bisexual women relied primarily on their families, but gay and bisexual men relied primarily on other LGB individuals. Racial/ethnic minority LGBs relied on LGB similar others at the same rate at White LGBs but, notably, racial/ethnic minority LGBs reported receiving fewer dimensions of support. PMID:26752447

    Thermodynamic and structural studies are commonly utilized to optimize small molecules for specific DNA interactions, and, thus, a significant amount of binding data is available. However, the dynamic processes that are involved in minor groove complex formation and maintenance are not fully understood. To help define the processes involved, we have conducted 1D and 2D NMR in conjunction with biosensor-SPR experiments with a variety of compounds and symmetric, as well as asymmetric, AT tract DNA sequences. Surprisingly, the NMR data clearly show exchange between equivalent binding sites for strongly binding compounds like netropsin and DB921 (Ka > 10(8) M(-1)) that does not involve dissociation off the DNA. A quantitative analysis of the data revealed that these bound exchange rates are indeed much faster than the macroscopic dissociation rates which were independently determined by biosensor-SPR. Additionally, we could show the existence of at least two 1:1 compound DNA complexes at the same site for the interaction of these compounds with an asymmetric DNA sequence. To explain this behavior we introduced a model in which the ligand is rapidly flipping between two orientations while in close association with the DNA. The ligand reorientation will contribute favorably to the binding entropy. As the potential of minor groove binders to form more than a single complex with asymmetric, as well as symmetric, duplexes is widely unknown, the consequences for binding thermodynamics and compound design are discussed.

    The Coping With Discrimination Scale (CDS) shows promise as a self-report measure of strategies for coping with racial discrimination. To assess the psychometric properties of the measure for use with sexual minorities (i.e., gay, lesbian, bisexual, or GLB persons), a nonprobability sample of 371 GLB adults completed the instrument along with several standardized, self-report measures. Confirmatory factor analyses supported the five-factor structure of the original scale with the exclusion of five items. Adequate internal consistency reliability was found. Internalization, drug and alcohol use, and detachment subscales were correlated positively with measures of psychological distress and negatively with a measure of life satisfaction, providing evidence of construct validity. The education/advocacy and resistance subscales were largely unrelated to concurrently administered validation measures, consistent with prior findings. Coping strategy use varied as a function of primary sources of social support. The CDS appears to be a psychometrically sound measure of several discrimination coping strategies for use with sexual minorities.

    We have studied the conformational effects of 4-aminobiphenyl modification at C-8 of guanine or adenine on double-stranded DNA trimers. We used sequences with the modified purine at the central base pair and all 16 possible neighboring sequences at the outer pairs. Minimized potential energy calculations were carried out using the molecular mechanics program DUPLEX to survey the conformation space of these adducts, using a total of 1280 starting structures both in the modified guanine series and in the modified adenine series. Conformer families in which the bound 4-aminobiphenyl was located in the DNA major groove, and in the minor groove, were located for both adenine and guanine modification. In the modified guanine series, the major and minor groove families were roughly comparable in energy, and the sequence context determined which was more stable in a particular case. In the modified adenine series, however, the minor groove structure was more that 10 kcal/mol more stable than the major groove for all sequences. As a result, minor groove adducts provided most of the global minima in the adenine-modified series. This result may be relevant to a previous mutagenesis study [Lasko et al. (1988) J. Biol. Chem. 263, 15429-15435] in which the hot spot of most frequent occurrence was located at an adenine, in the sequence GAT. 25 refs., 9 figs., 4 tabs.

The first type, structure vector A (-Py[Me]-γ-Py-Ind), has a methyl group present as a substituent on the nitrogen of pyrrole B, connected to the C terminal of the oligoamide fragment. The second type, structure vector B (-Py[(CH(2))(11)OH]-γ-Py-Ind), has an alkyl chain present on the nitrogen of pyrrole B connected to the C terminal of the oligoamide fragment and has been designed to access to di- and multivalent sugar-oligoamides. By using sequential DIPC/HOBt coupling reactions, the oligoamide fragment -Py[R]-γ-Py-Ind has been constructed. The last coupling reaction between the anomeric amino sugar and the oligoamide fragment was carried out by activating the acid derivative as a BtO- ester, which has been performed by using TFFH. The isolated esters (BtO-Py[R]-γ-Py-Ind) were coupled with selected amino sugars using DIEA in DMF. The synthesis of two different selective model vectors (vector A (1) and vector B (2)) and two types of water-soluble sugar-oligoamide ligands, with vector A structure (compounds 3-7) and with vector B structure (compound 8), was carried out.

  6. End stage renal disease in minorities.

    Cruz, I. A.; Hosten, A. O.

    1991-01-01

    It is projected that the proportion of black Americans, American Indians, Asian Americans, and Hispanic Americans entering the ESRD program will continue to increase. Despite the increase in the average age of the ESRD population, the minorities entering the ESRD program are much younger. The major risk factors of ESRD--hypertension, diabetes, and glomerulonephritis--are affecting these minorities at a higher rate and in varying combinations. High prevalence and severity of hypertension followed by diabetes mellitus are the major risk factors in blacks, especially black women. Heroin and HIV nephropathies, tied to the epidemic of illicit drug abuse, have a major impact on young black men. The high prevalence of diabetes and the epidemic of glomerulonephritis in certain tribes are the major risk factors in American Indians. Hypertension and diabetes are the risk factors for the rapidly increasing Asian American population, especially for the elderly segment of this population. Diabetes predominates as the risk factor for the rapidly growing Hispanic American population, a group that needs to be identified separately within the ESRD program. Diabetes and hypertension are treatable, and adequate control can prevent progression of renal failure. However, with minority groups, it is difficult to fully implement the measures necessary to achieve this control. Outreach programs are necessary not only to provide medical treatment but to include instruction in socioeconomic and educational strategies. Programs that will seek out these patients and treat them should also educate them about their diet, about the detrimental effects of alcohol and smoking, and about the danger of substance abuse. Ultimately, these programs may be much cheaper than supporting a rapidly increasing ESRD program. PMID:1920501

  7. Special Report - American Minorities in Astronomy

    NASA Astrophysics Data System (ADS)

    1995-05-01

    There are about 15 African-American professional astronomers in the United States. Not 15 percent, fifteen. Latinos and Native Americans are similarly underrepresented. Those who make it not only must run the usual gauntlet of school, college, graduate school, and the job market; they must jump extra hurdles that can include poverty, discrimination, isolation, expectations of failure, and the burden of "representing" their ethnic group to their profession and their profession to their ethnic group. Over the past two decades, astronomers have worked to improve women's representation in their profession. What can we do to support American minority groups? Mercury h as asked astronomers, educators, and students from various perspectives to comment.

  8. Evolutionary Minority Game with searching behavior

    NASA Astrophysics Data System (ADS)

    Zhang, Wei; Sun, Yuxin; Feng, Xu; Xiong, Xiong

    2015-10-01

    In this paper, we determine the impact of searching behavior on the evolutionary minority game (EMG). We introduce searching behavior in two ways: optimal neighbor searching and global searching. Our study investigates the distribution equilibriums of probabilities that agents follow a given strategy and on system performance of the game. The results indicate that the distribution equilibriums of the probabilities are different with searching behavior, as opposed to without searching behavior. The system performance becomes worse after adding the searching behavior. Additionally, we test other variables in a standard EMG with and without searching behavior.

  9. Astrometric observations of comets and minor planets

    NASA Technical Reports Server (NTRS)

    Williams, J. G.; Gibson, J.

    1991-01-01

    Comets and planet crossing asteroids are observed so that accurate positions can be determined. The observations are made with the Palomar 1.5 m telescope equipped with a CCD array. The combination of telescope and detector is quite effective at recording faint comets and minor planets. This proves useful for early acquisition of comets and asteroids returning for a new opposition. The resulting positions permit accurate orbits to be determined and allow the properties of the comets and asteroids to be measured by other observers using a variety of techniques. Recoveries and other notable observations of comets and planet crossing asteroids observed during the past years are discussed.

    2010-01-01

    This article summarizes data from a qualitative study investigating the ways in which female youth perceive and respond to challenges related to the interplay of late adolescence and a minority sexual orientation. Fifteen sexual minority females in late adolescence were interviewed individually and in focus groups. The interviews focused on participants' perceptions of challenges, the impact those stressors have in their lives, and methods they utilize to cope with them. The most common negative experiences reported were isolation, lack of acceptance, harassment, and violence. Sub-themes include: hearing negative messages about gender and sexual orientation, pressures to conform to a variety of cultural norms including gender norms, fears of future violence, and pressure to identify sexual orientation. Collectively, the participants described these negative consequences of experiences of heterosexism, sexism, and racism as their most difficult experiences. The most common responses to these stressors reported by participants were finding support in relationships, engaging in coping responses, pursuing education and activism, rebellion and resistance, and avoidance and deferment.

  4. Assessment of acculturation in minority health research.

    2017-03-01

    Acculturation represents an important construct in the context of health disparities. Although several studies have reported relationships between various aspects of acculturation and health in minority populations, crucial inconsistencies remain. One likely reason for these inconsistencies may relate to limitations in the conceptualization and operationalization of acculturation, particularly in the context of health research. The acculturation construct underwent major conceptual and operational change when it was adapted from anthropology to psychology, and we argue another major shift is now required for use of this construct in health research. Issues include determining whether acculturation measures should focus on an individual's internal attitudes or overt behaviors; whether they should characterize cultural orientation status at a given point in time or change over time; whether measures should be culture-specific or more global in nature; how the issue of multiculturalism should be addressed; how measures can optimally incorporate multiple dimensions of acculturation; and whether proxy measures should be used. These issues are important in the context of health research because of their implications for determining the direct and indirect effects of cultural change on health-related biological and behavioral processes. We elaborate on and address each of these issues from a perspective that spans multiple disciplines across the biological and social sciences, and offer concrete recommendations with the ultimate goal of achieving a better understanding of the role of acculturation in minority health and health disparities.

    2007-01-01

    OBJECTIVES: To assess American newspaper coverage regarding racial and ethnic minority health disparities (MHDs). METHODS: LexisNexis was queried with specific word combinations to elicit all MHD articles printed in 257 newspapers from 2000-2004. The full texts were read and articles categorized by racial/ethnic group and specific MHD topics mentioned. RESULTS: In the five years from 2000-2004, 1188 MHD articles were published, representing 0.09% of all articles about health. Newspapers gave much attention to MHD when discussed in conferences and meetings and speeches by senior health officials and politicians. Cancer, cardiovascular disease and HIV/AIDS were most frequent among disease-specific mentions. Articles about African Americans comprised 60.4% of all race/ethnicity-mentioning articles. CONCLUSIONS: Despite the release of major organizational reports and the publication of many studies confirming the prevalence of MHD, few newspaper articles have been published explaining MHD to the public. Because of the general public's low rate of health literacy, the health world should collaborate with the media to present a consistent, simple message concerning gaps in care experienced by all racial/ethnic minority groups. In a time of consumer-directed healthcare, if Americans understand that MHDs exist, they may galvanize to advocate for disparity elimination and quality improvement. PMID:17987915

    2016-02-01

    There is a dearth of research on mechanisms underlying higher rates of suicidal ideation among gay men compared to heterosexual men. The purpose of this study was to establish the link between social/psychological predictor variables and suicidal ideation by testing a hypothesized minority stress model. Structural equation modeling was used to assess the relationships posited in the model using data from a community sample of 167 gay men. Model fit was adequate and hypothesized relationships were partially supported. Also, depressive symptoms partially mediated the relationship between (less) outness predicting suicidal ideation. These findings imply that therapeutic approaches targeting the coming out process may be more effective than approaches targeting internalized homophobia when suicidal ideation is indicated in the clinical presentation of gay and bisexual men.

    2010-08-01

    A case of combined hepatocellular-cholangiocarcinoma (CHCC) in an adult male lesser flamingo (Phoenicopterus minor) that was part of a breeding programme at a private facility is reported. Grossly, the liver was markedly enlarged with multifocal, well-circumscribed, pinpoint to 2 cm diameter pale tan nodular masses. Histologically, the hepatic parenchyma was replaced by neoplastic cells that demonstrated hepatocellular and, less frequently, biliary epithelial cell differentiation. Positive pan-cytokeratin (AE1/AE3/PCK26) immunolabelling of the neoplastic cells forming bile ducts with the scattered immunoreactivity of cells forming glandular structures within the areas of hepatocellular differentiation supported the diagnosis. No metastases were detected. CHCC is a rare neoplasm in mammals and birds. This is the first report where gross, histological, and immunohistochemical characteristics of CHCC in a bird are described, and the first report of CHCC in a lesser flamingo.

    2013-01-01

    Background Equity in health is a pressing concern and reaching disadvantaged populations is necessary to close the inequity gap. To date, the discourse has predominately focussed on reaching the poor. At the same time and in addition to wealth, other structural determinants that influence health outcomes exist, one of which is ethnicity. Inequities based on group belongings are recognised as ‘horizontal’, as opposed to the more commonly used notion of ‘vertical’ inequity based on individual characteristics. Objective The aim of the present review is to highlight ethnicity as a source of horizontal inequity in health and to expose mechanisms that cause and maintain this inequity in Vietnam. Design Through a systematic search of available academic and grey literature, 49 publications were selected for review. Information was extracted on: a) quantitative measures of health inequities based on ethnicity and b) qualitative descriptions explaining potential reasons for ethnicity-based health inequities. Results Five main areas were identified: health-care-seeking and utilization, maternal and child health, nutrition, infectious diseases, and oral health and hygiene. Evidence suggests the presence of severe health inequity in health along ethnic lines in all these areas. Research evidence also offers explanations derived from both external and internal group dynamics to this inequity. It is reported that government policies and programs appear to be lacking in culturally adaptation and sensitivity, and examples of bad attitudes and discrimination from health staff toward minority persons were identified. In addition, traditions and patriarchal structures within ethnic minority groups were seen to contribute to the maintenance of harmful health behaviors within these groups. Conclusion Better understandings of the scope and pathways of horizontal inequities are required to address ethnic inequities in health. Awareness of ethnicity as a determinant of health, not

    The Cleveland State University Minority Engineering Program Pipeline consist of programs which foster engineering career awareness, academic enrichment, and professional development for historically underrepresented minority studies. The programs involved are the Access to Careers in Engineering (ACE) Program for high school pre-engineering students: the LINK Program for undergraduate students pursuing degree which include engineering; and the PEP (Pre-calculus Enrichment Program) and EPIC (Enrichment Program in Calculus) mathematics programs for undergraduate academic enrichment. The pipeline is such that high school graduates from the ACE Program who enroll at Cleveland State University in pursuit of engineering degrees are admitted to the LINK Program for undergraduate level support. LINK Program students are among the minority participants who receive mathematics enrichment through the PEP and EPIC Programs for successful completion of their engineering required math courses. THese programs are interdependent and share the goal of preparing minority students for engineering careers by enabling them to achieve academically and obtain college degree and career related experience.

    2013-01-01

    This study examined risk and protective outcomes by comparing homeless sexual minority youths to heterosexual homeless youths regarding family, peer behaviors, school, mental health (suicide risk and depression), stigma, discrimination, substance use, and sexual risk behaviors. Structured interviews (N = 147) were conducted with individuals ages 16-24 at three drop-in programs serving homeless youths in Toronto. Bivariate analyses indicated statistically significant differences between homeless sexual minorities (n=66) and their heterosexual counterparts (n=81) regarding all variables: family, peer behaviors, stigma, discrimination, mental health, substance use and sexual risk behaviors with the exception of school belonging. Specifically, homeless sexual minority youths fared more poorly (e.g. lower satisfaction with family communication, experienced more stigma, used more drugs and alcohol) than their heterosexual counterparts. Improving family communication may be a worthwhile intervention if the youths are still in contact with their families. Future research should focus on victimization in the context of multiple systems.

  16. Predictive binding geometry of ligands to DNA minor groove: isohelicity and hydrogen-bonding pattern.

    PubMed

    Stockert, Juan C

    2014-01-01

    The interaction of drugs and dyes with nucleic acids, particularly when binding to DNA minor groove occurs, has increasing importance in biomedical sciences. This is due to the resulting biological activity and to the possibility of recognizing AT and GC base pairs. In such cases, DNA binding can be predicted if appropriate helical and hydrogen-bonding parameters are deduced from DNA models, and a simplified geometrical rule in the form of a stencil is then applied on computer-drawn molecules of interest. Relevant structure parameter values for minor groove binders are the length (4.6 < L < 5.4 Å) and angle (152 < σ < 156.5°) between three consecutive units, measured at the level of hydrogen donor or acceptor groups. Application of the stencil shows that predictive methods can aid in the design of new compounds, by checking the possible binding of isohelical sequence-specific ligands along the DNA minor groove.

    Black sexual minority women are triply marginalized due to their race, gender, and sexual orientation. We compared three dimensions of discrimination-frequency (regularity of occurrences), scope (number of types of discriminatory acts experienced), and number of bases (number of social statuses to which discrimination was attributed)-and self-reported mental health (depressive symptoms, psychological well-being, and social well-being) between 64 Black sexual minority women and each of two groups sharing two of three marginalized statuses: (a) 67 White sexual minority women and (b) 67 Black sexual minority men. Black sexual minority women reported greater discrimination frequency, scope, and number of bases and poorer psychological and social well-being than White sexual minority women and more discrimination bases, a higher level of depressive symptoms, and poorer social well-being than Black sexual minority men. We then tested and contrasted dimensions of discrimination as mediators between social status (race or gender) and mental health outcomes. Discrimination frequency and scope mediated the association between race and mental health, with a stronger effect via frequency among sexual minority women. Number of discrimination bases mediated the association between gender and mental health among Black sexual minorities. Future research and clinical practice would benefit from considering Black sexual minority women's mental health in a multidimensional minority stress context.

    RNA polymerase II (pol II) encounters numerous barriers during transcription elongation, including DNA strand breaks, DNA lesions, and nucleosomes. Pyrrole-imidazole (Py-Im) polyamides bind to the minor groove of DNA with programmable sequence specificity and high affinity. Previous studies suggest that Py-Im polyamides can prevent transcription factor binding, as well as interfere with pol II transcription elongation. However, the mechanism of pol II inhibition by Py-Im polyamides is unclear. Here we investigate the mechanism of how these minor-groove binders affect pol II transcription elongation. In the presence of site-specifically bound Py-Im polyamides, we find that the pol II elongation complex becomes arrested immediately upstream of the targeted DNA sequence, and is not rescued by transcription factor IIS, which is in contrast to pol II blockage by a nucleosome barrier. Further analysis reveals that two conserved pol II residues in the Switch 1 region contribute to pol II stalling. Our study suggests this motif in pol II can sense the structural changes of the DNA minor groove and can be considered a “minor groove sensor.” Prolonged interference of transcription elongation by sequence-specific minor groove binders may present opportunities to target transcription addiction for cancer therapy.

    2001-12-01

    Since 1971, the American Geological Institute (AGI) Minority Participation Program (MPP) has supported scholarships for underrepresented minorities in the geosciences at the undergraduate and graduate levels. Some of our MPP scholars have gone on to hugely successful careers in the geosciences. MPP scholars include corporate leaders, university professors, a NASA scientist-astronaut and a National Science Foundation (NSF) CAREER awardee. Yet as ethnic minorities continue to be underrepresented in the geosciences, AGI plans to expand its efforts beyond its traditional undergraduate and graduate scholarships to include diversity programs for secondary school geoscience teacher internships, undergraduate research travel support, and doctoral research fellowships. Funding for the MPP has come from multiple sources, including industry, scientific societies, individuals, and during the last 10 years, the NSF. College-level students apply for the MPP awards or award renewals, and the MPP Advisory Committee selects scholarship recipients based upon student academic performance, financial need, and potential for success as a geoscience professional. Mentoring is a long-standing hallmark of the AGI MPP. Every AGI MPP scholar is assigned a professional geoscientist as a mentor. The mentor is responsible for regular personal contacts with MPP scholars. The MPP Advisory Committee aims to match the profession of the mentor with the scholar's academic interest. Throughout the year, mentors and scholars communicate about possible opportunities in the geosciences such as internships, participation in symposia, professional society meetings, and job openings. Mentors have also been active in helping younger students cope with the major changes involved in relocating to a new region of the country or a new college culture. We believe that AGI is well-positioned to advance diversity in the geosciences through its unique standing as the major professional organization in the

    2004-12-01

    Over the past five years NASA has carried out a deliberate and highly successful effort to engage Minority Institutions (MI) in space science activities. Implemented through a uniquely designed grants program now known as the "NASA Minority University and College Education and Research Partnership Initiative (MUCERPI) in Space Science," an impressive array of space science research and educational activities has been developed at 15 MI's over the three-year period from January 1, 2001 to December 31, 2003. This effort began with the recognition that very few MI's had programs in space science. To address this deficiency, the NASA Office of Space Science (OSS), in cooperation with the NASA Office of Equal Opportunity Programs (OEOP), carried out a series of consultations with MI faculty and administrators aimed at ascertaining the level of interest that MI's had in space science and at identifying the most effective strategies for developing space science capabilities on their campuses. The clear conclusion was that MI's were extremely interested in participating in space science, but that they had not been given a real opportunity to do so. The overwhelming consensus was that a successful program to engage MI's in space science would require: 1) a serious invitation from OSS to become involved in space science, 2) the flexibility to devise projects that fit the local environment on each participating campus, and 3) the opportunity to form partnerships with leading researchers in the space science community. As a result, a NASA Research Announcement (NRA) emphasizing these and other factors was developed and issued in January 2000. Some of its more unique features were that: 1) it was issued by OSS with funding provided by OEOP; 2) it invited MI's to develop any combination of research capabilities, academic programs (at any level), and/or public outreach in space science; and 3) it required working partnerships with NASA-sponsored space science researchers for any

    The number of unaccompanied immigrant minors (UIMs) from Central America significantly increased in 2014. Nearly 50,000 children from El Salvador, Guatemala, and Honduras crossed the United States-Mexico border in 2014, compared with 3,933 in 2011. Few resources exist to guide pediatric nurse practitioners (PNPs) in their care of UIM. The multifactorial reasons behind migration and the state of children's health in Central America provide insight into the needs of UIMs. Guidelines for similar groups such as foreign-born children and refugees offer direction for the health care considerations of UIMs. This article provides demographic information on UIMs, highlights the unique and challenging medical and mental health issues facing UIMs, and discusses the role of the PNP. A UIM's initial visit with a PNP serves as an opportunity to build trust through culturally competent, trauma-informed care, provide preventive care, assess for unmet health needs, and screen for mental health conditions.

    Many dynamical systems produce large quantities of data. How can the system be understood from the output data? Often people are simply overwhelmed by the data. Traditional tools such as tables and plots are often not adequate, and new techniques are needed to help people to analyze the system. In this paper, we propose the use of two spacefilling visualization tools to examine the output from a complex agent-based financial model. We measure the effectiveness and performance of these tools through usability experiments. Based on the experimental results, we develop two new visualization techniques that combine the advantages and discard the disadvantages of the information visualization tools. The model we use is an evolutionary version of the Minority Game which simulates a financial market.

    Members of the Joint Working Group on Improving Underrepresented Minorities (URMs) Persistence in Science, Technology, Engineering, and Mathematics (STEM)-convened by the National Institute of General Medical Sciences and the Howard Hughes Medical Institute-review current data and propose deliberation about why the academic "pathways" leak more for URM than white or Asian STEM students. They suggest expanding to include a stronger focus on the institutional barriers that need to be removed and the types of interventions that "lift" students' interests, commitment, and ability to persist in STEM fields. Using Kurt Lewin's planned approach to change, the committee describes five recommendations to increase URM persistence in STEM at the undergraduate level. These recommendations capitalize on known successes, recognize the need for accountability, and are framed to facilitate greater progress in the future. The impact of these recommendations rests upon enacting the first recommendation: to track successes and failures at the institutional level and collect data that help explain the existing trends.

  6. Damage distant airblast from MINOR SCALE

    An unexpected change in winds at 4-5 km MSL caused airblast ducting and focusing on Carrizozo, NM, 60 km east from MINOR SCALE. In result, this 4.8-kt ANFO (ammonium nitrate-fuel oil) explosion test, rattled the town with 300 Pa (0.0435 psi) overpressure, according to the microbarograph records. Four large (8 x 10 ft) store windows are broken. Weather data which were collected during this event show that conditions changed near shot time, as needed to explain this result. It appears that the variability of winds over the mountains region around WSMR is appreciably larger than over flatter terrain, so that airblast propagation predictions are subject to significant error. Microbarographs are essential in surrounding communities, to document the explosion airblast strength when unexpectedly enhanced blasts occur. The provided empirical model for estimating window damage from expected overpressure appeared to work well. As expected, large windows were the first to fail from the blast.

  7. Towards the Enhancement of "MINOR" Archaeological Heritage

    The research is an analysis of the recording, reconstruction and visualisation of the 3D data of a XVIII century watermill, identified in an emergency archaeological excavation during the construction of the mini-hydroelectric plant on the bank of the Adda river in the municipality of Pizzighettone (Cremona, Lombardy, Italy). The work examines the use and the potentials of modern digital 3D modelling techniques applied to archaeological heritage aimed to increase the research, maintenance and presentation with interactive products. The use of three-dimensional models managed through AR (Augmented Reality) and VR (Virtual Reality) technologies with mobile devices gives several opportunities in the field of study and communication. It also improves on-site exploration of the landscape, enhancing the "minor" archaeological sites, daily subjected to numerous emergency works and facilitating the understanding of heritage sites.

    Summary The first aid for burns is to run cold water over the burn for 20 minutes. This is effective for up to three hours after the injury. Assess the affected body surface area using the rule of nines. Consult a burn unit if more than 5% of the total body surface area is burnt in a child or if more than 10% in an adult. Extensive or deep burns and burns to special areas, such as the hands, should be referred. Chemical or electrical burns should also be assessed by a burn unit. For minor burns, antimicrobial dressings are recommended, but oral antibiotics should be avoided unless there are signs of infection. As burns are tetanus prone, check the patient’s immunisation status. Burns that become infected or are slow to heal should be discussed with a burn unit. The burn unit can also provide advice if there are uncertainties about how to manage a patient. PMID:26648640

  9. Probing Minor Groove Hydrogen Bonding Interactions between RB69 DNA Polymerase and DNA

    Minor groove hydrogen bonding (HB) interactions between DNA polymerases (pols) and N3 of purines or O2 of pyrimidines have been proposed to be essential for DNA synthesis from results obtained using various nucleoside analogues lacking the N3 or O2 contacts that interfered with primer extension. Because there has been no direct structural evidence to support this proposal, we decided to evaluate the contribution of minor groove HB interactions with family B pols. We have used RB69 DNA pol and 3-deaza-2'-deoxyadenosine (3DA), an analogue of 2-deoxyadenosine, which has the same HB pattern opposite T but with N3 replaced with a carbon atom. We then determined pre-steady-state kinetic parameters for the insertion of dAMP opposite dT using primer/templates (P/T)-containing 3DA. We also determined three structures of ternary complexes with 3DA at various positions in the duplex DNA substrate. We found that the incorporation efficiency of dAMP opposite dT decreased 10{sup 2}-10{sup 3}-fold even when only one minor groove HB interaction was missing. Our structures show that the HB pattern and base pair geometry of 3DA/dT is exactly the same as those of dA/dT, which makes 3DA an optimal analogue for probing minor groove HB interactions between a DNA polymerase and a nucleobase. In addition, our structures provide a rationale for the observed 10{sup 2}-10{sup 3}-fold decrease in the rate of nucleotide incorporation. The minor groove HB interactions between position n-2 of the primer strand and RB69pol fix the rotomer conformations of the K706 and D621 side chains, as well as the position of metal ion A and its coordinating ligands, so that they are in the optinal orientation for DNA synthesis.

  10. Validation of the internalization of the Model Minority Myth Measure (IM-4) and its link to academic performance and psychological adjustment among Asian American adolescents.

    There is limited research examining psychological correlates of a uniquely racialized experience of the model minority stereotype faced by Asian Americans. The present study examined the factor structure and fit of the only published measure of the internalization of the model minority myth, the Internalization of the Model Minority Myth Measure (IM-4; Yoo et al., 2010), with a sample of 155 Asian American high school adolescents. We also examined the link between internalization of the model minority myth types (i.e., myth associated with achievement and myth associated with unrestricted mobility) and psychological adjustment (i.e., affective distress, somatic distress, performance difficulty, academic expectations stress), and the potential moderating effect of academic performance (cumulative grade point average). Results suggested the 2-factor model of the IM-4 had an acceptable fit to the data and supported the factor structure using confirmatory factor analyses. Internalizing the model minority myth of achievement related positively to academic expectations stress; however, internalizing the model minority myth of unrestricted mobility related negatively to academic expectations stress, both controlling for gender and academic performance. Finally, academic performance moderated the model minority myth associated with unrestricted mobility and affective distress link and the model minority myth associated with achievement and performance difficulty link. These findings highlight the complex ways in which the model minority myth relates to psychological outcomes.

    This article describes the 6-week Health Careers Enhancement Program for Minorities inaugurated in the summer of 1988 at Case Western Reserve University School of Medicine. The program was developed for minority and economically disadvantaged college undergraduates and postbaccalaureate premedical students. Its major objectives were to stimulate and maintain the interest of minority students in health careers and prepare these students for entry into health professions and for successful completion of these programs. A unique aspect of the program was academic outreach. Case Western Reserve University minority alumni and community minority physicians participated as clinical role models, mentors, and teachers; community and state minority leaders served as inspirational speakers and role models. The program was designed not only to incorporate cognitive and skill development activities, but to also include features distinctive to the Case Western Reserve University curriculum, specifically, organ system teaching, preceptor groups, medical apprenticeship program, and student tutors.

    A 100-man keyworker blast shelter was constructed and tested at the predicted 75-psi peak overpressure level in the MINOR SCALE Event in June 1985 at the White Sands Missile Range, New Mexico. The MINOR SCALE Event was a high-explosive test simulating the air-blast effects of an 8-KT nuclear weapon. The reinforced concrete shelter was designed by the US Army Engineer Division, Huntsville and the US Army Engineer Waterways Experiment Station under the sponsorship of the Federal Emergency Management Agency. The experiment was conducted to verify the structural design of the shelter. The full-scale structure was complete with air-handling equipment, bunks, and instrumented anthropomorphic mannequins. The survivability of mechanical air-moving equipment inside the shelter and occupant survivability were investigated. The structure experienced minor damage during the test. Permanent roof deflections were 1/8 inch or less. The mechanical equipment incurred no damage, and in-structure shock in the shelter was within acceptable limits for occupants. The test indicated that the shelter will safely protect personnel when subjected to the design peak overpressure of 50 psi from a 1-MT nuclear weapon. Recommendations resulting from the experiment included the retesting of the structure using a High-Explosive Simulation Technique (HEST) test to introduce significant damage to the shelter.

    This report describes an undergraduate minor program in wind energy that has been developed at Iowa State University. The minor program targets engineering and meteorology students and was developed to provide interested students with focused technical expertise in wind energy science and engineering, to increase their employability and ultimate effectiveness in this growing industry. The report describes the requirements of the minor program and courses that fulfill those requirements. Five new courses directly addressing wind energy have been developed. Topical descriptions for these five courses are provided in this report. Six industry experts in various aspects of wind energy science and engineering reviewed the wind energy minor program and provided detailed comments on the program structure, the content of the courses, and the employability in the wind energy industry of students who complete the program. The general consensus is that the program is well structured, the course content is highly relevant, and students who complete it will be highly employable in the wind energy industry. The detailed comments of the reviewers are included in the report.

    This article explores the results of a qualitative community-based research project on the intersectional experiences of sexual minority refugees living in Canada. Undertaken between 2008 and 2010, this study examines sexual minority refugees' multifaceted experiences of migration, the refugee determination process, and settlement. Through an analysis of the interrelated themes of identity, refugeeness, and belonging, we hope to further investigate the ways in which Canadian refugee policies, social institutions, and dominant discourses contribute to the sociopolitical construction of sexual minority refugees. We conclude with an exploration of strategies for increasing protection of sexual minority refugees in Canada.

  3. Maturing the minor, marginalizing the family: on the social construction of the mature minor.

    PubMed

    Barina, Rachelle; Bishop, Jeffrey P

    2013-06-01

    The doctrine of the mature minor began as an emergency exception to the rule of parental consent. Over time, the doctrine crept into cases that were non-emergent. In this essay, we show how the doctrine also developed in the context of the latter part of the 20th century, at the same time that the sexual revolution, the pill, and sexual liberation came to be seen as important symbols of female liberation--liberation that required that female minors be granted the status of a mature minor. To do so moves sexual morality out of the domain of the family, where it had always been situated, and into the domain of the state. We also show how a phenomenological account of the care of the body in the family conforms to the latest in neuroscientific understandings of adolescent brain development. The family attenuates the dependency of adolescents and provides an important social contextualization for the care of the body, including the inculcation of sexual mores in adolescence. We conclude that the drive to push sexual decision making as a matter of state concern further undermines the foundations of the moral meanings of sex and sexuality.

  4. Minor Planet Center Data Processing Challenges

    2015-08-01

    The Minor Planet Center (MPC) is the single worldwide location for receipt and distribution of positional measurements of minor planets, comets and outer irregular natural satellites of the major planets. The MPC is responsible for the identification, designation and orbit computation for all of these objects.Over 2 million observations are received each month via the internet, and are validated and processed in near real time. The observations come in batches whose formats are checked and whose observations are run through a number of other routine checks such as departure from great circle motion, prior publication, single observations, near duplicates, etc. Some or all of a batch of observations may be returned to its sender if they fail one or more of the checks. After the observations have been validated, they are processed to produce orbits of newly discovered objects or used to update the orbits of known objects.Given the volume of observations, the sheer number of known objects against which to possibly match, the shortness of the time interval over which each object was likely observed, and the uncertainties in the positions, and occasionally possible errors in times, reported, a number of data processing challenges face the MPC. These include the following: Identifying observations of objects reported as new with already known objects; linking together sets of observations from different nights (possibly at different apparitions) which may belong to the same object; determining if a set of observations has been assigned to the wrong object; determining if an object with a very short arc is possibly a Near-Earth object; determining and examining the range of possible variant orbits of newly discovered Near-Earth objects with very short observation arcs for cases which indicate an object is potentially on a collision course with Earth; linking observations to known artificial satellites and/or booster stages and other space "junk"; prioritizing newly

  5. Pseudomonas aeruginosa Minor Pilins Prime Type IVa Pilus Assembly and Promote Surface Display of the PilY1 Adhesin*

    Type IV pili (T4P) contain hundreds of major subunits, but minor subunits are also required for assembly and function. Here we show that Pseudomonas aeruginosa minor pilins prime pilus assembly and traffic the pilus-associated adhesin and anti-retraction protein, PilY1, to the cell surface. PilV, PilW, and PilX require PilY1 for inclusion in surface pili and vice versa, suggestive of complex formation. PilE requires PilVWXY1 for inclusion, suggesting that it binds a novel interface created by two or more components. FimU is incorporated independently of the others and is proposed to couple the putative minor pilin-PilY1 complex to the major subunit. The production of small amounts of T4P by a mutant lacking the minor pilin operon was traced to expression of minor pseudopilins from the P. aeruginosa type II secretion (T2S) system, showing that under retraction-deficient conditions, T2S minor subunits can prime T4P assembly. Deletion of all minor subunits abrogated pilus assembly. In a strain lacking the minor pseudopilins, PilVWXY1 and either FimU or PilE comprised the minimal set of components required for pilus assembly. Supporting functional conservation of T2S and T4P minor components, our 1.4 Å crystal structure of FimU revealed striking architectural similarity to its T2S ortholog GspH, despite minimal sequence identity. We propose that PilVWXY1 form a priming complex for assembly and that PilE and FimU together stably couple the complex to the major subunit. Trafficking of the anti-retraction factor PilY1 to the cell surface allows for production of pili of sufficient length to support adherence and motility. PMID:25389296

    We measured the ionized-gas and stellar kinematics along the major and minor axis of a sample of 10 early-type spirals. Much to our surprise we found a remarkable gas velocity gradient along the minor axis of 8 of them. According to the kinematic features observed in their ionized-gas velocity fields, we divide our sample galaxies in three classes of objects. (i) NGC 4984, NGC 7213, and NGC 7377 show an overall velocity curve along the minor axis without zero-velocity points, out to the last measured radius, which is interpreted as due to the warped structure of the gaseous disk. (ii) NGC 3885, NGC 4224, and NGC 4586 are characterized by a velocity gradient along both major and minor axis, although non-zero velocities along the minor axis are confined to the central regions. Such gas kinematics have been explained as being due to non-circular motions induced by a triaxial potential. (iii) NGC 2855 and NGC 7049 show a change of slope of the velocity gradient measured along the major axis (which is shallower in the center and steeper away from the nucleus), as well as non-zero gas velocities in the central regions of the minor axis. This has been attributed to the presence of a kinematically-decoupled gaseous component in orthogonal rotation with respect to the galaxy disk, namely an inner polar disk. The case and origin of inner polar disks are discussed and the list of their host galaxies is presented. Based on observations carried out at the European Southern Observatory (ESO 62.A-0463 and 63.N-0305).

    Prior research on female sex workers (FSW) in China, and their risk for HIV and STI, neglects the nuanced experiences of ethnic minority FSW. We conducted participant observations and in-depth interviews with 33 FSW and six venue bosses to describe the experiences of FSW and management structures in high and low-priced sex work venues in Liuzhou, China. In low-priced venues, FSW had more autonomy and stronger relationships with their ethnic minority peers. Mid and high-priced venues had more formal management structures. Ethnic minority FSW working in higher priced venues experienced less support and kinship with their peers. HIV/STI prevention outreach activities occurred in all of the venues, but they were not tailored for different venue types or for ethnic minority FSW. Our findings provide guidance for tailoring public health programs that meet the needs of ethnic minority women working in different types of sex work venues. PMID:23912337

    Objective The aim of this study was to examine a cohort of unaccompanied refugee minors (URMs) by means of psycholinguistic methods in order to obtain a more subtle picture of their degree of traumatization. Methods Twenty-eight participants were included in the Stress-Inducing Speech Task (SIST) consisting of a free association (FA) and a stress (STR) condition. Narratives were examined by means of (1) quantitative parameters (word count); (2) psycholinguistic variables (temporal junctures, TJs), narrative structure, referential activity (RA)—a measure of emotional expressivity; and (3) content analysis ratings. Results Word count was significantly lower than in age-matched norms. In the FA condition, TJs were lower, but in the STR condition, rates were comparable. RA was significantly higher in both conditions. Content analysis ratings showed that the experiences described by these youths were potentially traumatic in nature. Conclusions This pattern of narrative shows a mixture of fulfilling the task demand, while containing an emotionally charged narrative. Narrative structure was absent in the FA condition, but preserved in the STR condition, as URMs struggled with the description of non-normative events. This indicates that these youths have not yet emotionally dealt with and fully integrated their trauma experiences. PMID:26955827

    Members of the Joint Working Group on Improving Underrepresented Minorities (URMs) Persistence in Science, Technology, Engineering, and Mathematics (STEM)—convened by the National Institute of General Medical Sciences and the Howard Hughes Medical Institute—review current data and propose deliberation about why the academic “pathways” leak more for URM than white or Asian STEM students. They suggest expanding to include a stronger focus on the institutional barriers that need to be removed and the types of interventions that “lift” students’ interests, commitment, and ability to persist in STEM fields. Using Kurt Lewin’s planned approach to change, the committee describes five recommendations to increase URM persistence in STEM at the undergraduate level. These recommendations capitalize on known successes, recognize the need for accountability, and are framed to facilitate greater progress in the future. The impact of these recommendations rests upon enacting the first recommendation: to track successes and failures at the institutional level and collect data that help explain the existing trends.

    Resource allocation takes place in various types of real-world complex systems such as urban traffic, social services institutions, economical and ecosystems. Mathematically, the dynamical process of resource allocation can be modeled as minority games. Spontaneous evolution of the resource allocation dynamics, however, often leads to a harmful herding behavior accompanied by strong fluctuations in which a large majority of agents crowd temporarily for a few resources, leaving many others unused. Developing effective control methods to suppress and eliminate herding is an important but open problem. Here we develop a pinning control method, that the fluctuations of the system consist of intrinsic and systematic components allows us to design a control scheme with separated control variables. A striking finding is the universal existence of an optimal pinning fraction to minimize the variance of the system, regardless of the pinning patterns and the network topology. We carry out a generally applicable theory to explain the emergence of optimal pinning and to predict the dependence of the optimal pinning fraction on the network topology. Our work represents a general framework to deal with the broader problem of controlling collective dynamics in complex systems with potential applications in social, economical and political systems.

    We report the results of an unprecedented real Minority Game (MG) played by university staff members who clicked one of two identical buttons (A and B) on a computer screen while clocking in or out of work. We recorded the number of people who clicked button A for 1288 games, beginning on April 21, 2008 and ending on October 31, 2010, and calculated the variance among the people who clicked A as a function of time. The evolution of the variance shows that the global gain of selfish agents increases when a small portion of agents make persistent choice in the games. We also carried out another experiment in which we forced 101 fish to enter one of the two symmetric chambers (A and B). We repeated the fish experiment 500 times and found that the variance of the number of fish that entered chamber A evolved in a way similar to the human MG, suggesting that fish have memory and can employ more strategies when facing the same situation again and again.

While AMS is not the optimum method for each particular plutonium isotope, the possibility to measure (239)Pu, (240)Pu, (241)Pu, (242)Pu and (244)Pu on the same AMS sputter target is a great simplification. We have obtained a first result on the global fallout value of (244)Pu/(239)Pu = (5.7 ± 1.0) × 10(-5) based on soil samples from Salzburg prefecture, Austria. Furthermore, we suggest using the (242)Pu/(240)Pu ratio as an estimate of the initial (241)Pu/(239)Pu ratio, which allows dating of the time of irradiation based solely on Pu isotopes. We have checked the validity of this estimate using literature data, simulations, and environmental samples from soil from the Salzburg prefecture (Austria), from the shut down Garigliano Nuclear Power Plant (Sessa Aurunca, Italy) and from the Irish Sea near the Sellafield nuclear facility. The maximum deviation of the estimated dates from the expected ages is 6 years, while relative dating of material from the same source seems to be possible with a precision of less than 2 years. Additional information carried by the minor plutonium isotopes may allow further improvements of the precision of the method.

    Resource allocation takes place in various types of real-world complex systems such as urban traffic, social services institutions, economical and ecosystems. Mathematically, the dynamical process of resource allocation can be modeled as minority games. Spontaneous evolution of the resource allocation dynamics, however, often leads to a harmful herding behavior accompanied by strong fluctuations in which a large majority of agents crowd temporarily for a few resources, leaving many others unused. Developing effective control methods to suppress and eliminate herding is an important but open problem. Here we develop a pinning control method, that the fluctuations of the system consist of intrinsic and systematic components allows us to design a control scheme with separated control variables. A striking finding is the universal existence of an optimal pinning fraction to minimize the variance of the system, regardless of the pinning patterns and the network topology. We carry out a generally applicable theory to explain the emergence of optimal pinning and to predict the dependence of the optimal pinning fraction on the network topology. Our work represents a general framework to deal with the broader problem of controlling collective dynamics in complex systems with potential applications in social, economical and political systems.

    Extraovarian sex cord-stromal tumor is an exceedingly uncommon entity that may cause a diagnostic dilemma clinically. We report a case of extraovarian fibroma with minor sex cord elements arising in the left broad ligament. The patient was a 66-year-old woman presenting with an intra-abdominal solid mass near the left ovary on magnetic resonance imaging. The tumor was located in the left broad ligament in contact with the left ovary and fallopian tube based on laparotomy findings. Histological examination revealed that the tumor was a fibroma that contained cell nests with aggregates resembling the Call-Exner bodies of granulosa cell tumors and irregularly shaped cell nests composed of undifferentiated sex cord-type cells. Cellular atypia or mitotic figures were not identified in any of the components. It was speculated that the possible site of origin of this tumor might be a supernumerary ovary in the broad ligament that was thought to be derived from embryonic remnants.
