    Polyploid speciation is an important source of angiosperm diversity. Insights into the origin and establishment of new polyploid species may be gained by studying the distributions of ancestral and derivative cytotypes at multiple spatial scales. Diploid (2n = 16) and tetraploid (2n = 32) snow buttercups (Ranunculus adoneus: Ranunculaceae) occur in the alpine of the central and southern Rocky Mountains. Root-tip squashes and flow cytometry were used to determine the ploidy of 1618 individuals from 35 populations. Samples from 31 of the 35 sites were entirely of one cytotype, either diploid or tetraploid. Diploid and tetraploid snow buttercups have nonoverlapping regional distributions. Where both cytotypes occur on the same site, the two are spatially segregated despite no apparent change in habitat. Triploid snow buttercups were only found at a diploid/tetraploid contact zone, while two hexaploid plants were found in tetraploid populations. Tetraploid establishment once or twice in the history of the species complex could account for the regional distribution of the two cytotypes. Habitat differentiation between cytotypes or reproductive exclusion of minority cytotypes may explain the observed segregation at both microgeographic and regional scales.

    Full Text Available In this study, we examined the chromosome number, detailed male meiosis, microsporogenesis, pollen fertility and morphological features and distribution of 2× and 4× cytotypes of Ranunculus hirtellus Royle, 1834. The majority of the populations scored now from cold regions of the northwest Himalayas showed tetraploid (n=16 meiotic chromosome count and one of the populations studied from the Manimahesh hills existed at diploid level (n=8. The individuals of diploid cytotype exhibited perfectly normal meiotic course resulting in 100% pollen fertility and pollen grains of uniform sizes. On the other hand, the plants of the tetraploid cytotype from all the populations in spite of showing normal bivalent formation and equal distribution to the opposite poles at anaphases showed various meiotic abnormalities. The most prominent among these meiotic abnormalities was the cytomixis which involved inter PMC (pollen mother cell chromatin material transfer at different stages of meiosis-I. The phenomenon of cytomixis induced various meiotic abnormalities which include chromatin stickiness, pycnotic chromatin, laggards and chromatin bridges, out of plate bivalents at metaphase-I, disoriented chromatin material at anaphase/telophase and micronuclei. Consequently, these populations exhibited varying percentages of pollen sterility (24 - 77 % and pollen grains of heterogeneous sizes. Analysis of various morphometric features including the stomata in 2× and 4× cytotypes showed that increase in ploidy level in the species is correlated with gigantism of vegetative and floral characters and the two cytotypes can be distinguished from each other on the basis of morphological characters. The distribution patterns of the 2× and 4× cytotypes now detected and 2×, 3×, 4× cytotypes detected earlier by workers from other regions of the Indian Himalayas have also been discussed.

    Patterns of ploidy variation among and within populations can provide valuable insights into the evolutionary mechanisms shaping the dynamics of plant systems showing ploidy diversity. Whereas data on majority ploidies are, by definition, often sufficiently extensive, much less is known about the incidence and evolutionary role of minority cytotypes. Ploidy and proportions of endoreplicated genome were determined using DAPI (4',6-diamidino-2-phenylindole) flow cytometry in 6150 Gymnadenia plants (fragrant orchids) collected from 141 populations in 17 European countries. All widely recognized European species, and several taxa of less certain taxonomic status were sampled within Gymnadenia conopsea sensu lato. Most Gymnadenia populations were taxonomically and/or ploidy heterogeneous. Two majority (2x and 4x) and three minority (3x, 5x and 6x) cytotypes were identified. Evolution largely proceeded at the diploid level, whereas tetraploids were much more geographically and taxonomically restricted. Although minority ploidies constituted <2 % of the individuals sampled, they were found in 35 % of populations across the entire area investigated. The amount of nuclear DNA, together with the level of progressively partial endoreplication, separated all Gymnadenia species currently widely recognized in Europe. Despite their low frequency, minority cytotypes substantially increase intraspecific and intrapopulation ploidy diversity estimates for fragrant orchids. The cytogenetic structure of Gymnadenia populations is remarkably dynamic and shaped by multiple evolutionary mechanisms, including both the ongoing production of unreduced gametes and heteroploid hybridization. Overall, it is likely that the level of ploidy heterogeneity experienced by most plant species/populations is currently underestimated; intensive sampling is necessary to obtain a holistic picture.

    Full Text Available Floral reward is important in ecological and evolutionary perspectives and essential in pollination biology. For example, floral traits, nectar and pollen features are essential for understanding the functional ecology, the dynamics of pollen transport, competition for pollinator services, and patterns of specialization and generalization in plant–pollinator interactions. We believe to present a synthetic description in the field of floral reward in Ranunculaceae family important in pollination biology and indicating connections between ecological and evolutionary approaches. The links between insect visitors’ behaviour and floral reward type and characteristics exist. Ranunculaceae is a family of aboot 1700 species (aboot 60 genera, distributed worldwide, however the most abundant representatives are in temperate and cool regions of the northern and southern hemispheres. The flowers are usually radially symmetric (zygomorphic and bisexual, but in Aconitum, Aquilegia are bilaterally symmetric (zygomorphic. Most Ranunculaceae flowers offer no nectar, only pollen (e.g., Ranunculus, Adonis vernalis, Thalictrum, but numerous species create trophic niches for different wild pollinators (e.g. Osmia, Megachile, Bombus, Andrena (Denisow et al. 2008. Pollen is a source of protein, vitamins, mineral salts, organic acids and hormones, but the nutritional value varies greatly between different plant species. The pollen production can differ significantly between Ranunculacea species. The mass of pollen produced in anthers differ due to variations in the number of developed anthers. For example, interspecies differences are considerable, 49 anthers are noted in Aquilegia vulgaris, 70 anthers in Ranunculus lanuginosus, 120 in Adonis vernalis. A significant intra-species differences’ in the number of anthers are also noted (e.g. 41 to 61 in Aquilegia vulgaris, 23-45 in Ranunculus cassubicus. Pollen production can be up to 62 kg per ha for Ranunculus acer

    Full Text Available Traditional treatment methods are often applied in our country. Ranunculaceae that grows as a weed in Sivas region is used topically in the treatment of rheumatic diseases. In this case, we present a 53-year- old patient who applied the ranunculaceae for knee pain topically and eventually, there appeared burn on the skin. The patient treated from wound debridement in our hospital, received wound care and was discharged. The occurence os such cases, uncontrolled and continuous use of herbal treatments can still be observed and research on plants leads people to act more consciously.

  9. Morphological development of petals in Ranunculaceae

    2016-04-01

    Full Text Available The petals, or the honey-leaves, are of great divergence in morphology in Ranunculaceae, i. e., tubular, bilabial, cup-shaped, flat, concaved or scaled at the base, with or without spur or succate. The previous observations showed that although the petals differ in mature morphology, they showed great similarity in the early development stage. The petal primordia are all hemispherical, rounded and much smaller than the sepal primordia, a relatively long plastochron exists between the last sepal and the first petal and differentiate into a blade and a short stalk. Thus, we assumed that the different morphology of the mature petals might be due to the morphological repatterning of petals in the development. To prove the hypothesis, the morphological development of the petals from 22 species from 20 genera, recovering all ten petalous clades and the major morphological types, in Ranunculaceae was observed by scanning electron microscope (SEM. The young petal undergoes the following developmental stages to the mature petal after it differentiates into blade and stalk. In the first stage, a depression appears at the base of the blade and the nectary tissue will appear in the depression in the later development. In the second stage, two bulges appear at the base of the depression that makes the petal bilabial and the bulges will be the upper lip of the petal and thus the blade will be the lower lip. In the third stage, two bulges become larger and fuse with one another at first and then fuse with the margins of the blade in each side, or each of the bulges fuses with the margin of the blade at first and then fuses with one another, or the bulges stop further growth and the depression deepened to form the succate or the spur. In the fourth stage, the lips, the two fused sides and the stalk growth in different speed. The divergence of development of different petals happens mainly in the third and the fourth stages and less divergence in the second and

    Full Text Available Four cytotypes of Simulium exiguum occur in Ecuador, where this morphospecies is the primary vector of onchocerciasis. In this paper, we give the first full description of the banding pattern of the larval polytene chromosomes of the Quevedo cytotypes differ from the chromosomal standard sequence (of the Cayapa cytotype by the fixed inversions IIL-5 and IIL-6. The Quevedo cytotype additionally differs from the standard and Bucay cytotypes by processing a differentiated X chromosome, wich is indicated by the inversion IIS-A. As the degree of reproductive isolation between the Bucay and Quevedo cytotypes has not yet been estabilished, they must be regarded as intraspecific variants of the same species. In fact, isoenzyme characterizations showed that the Bucay and Quevedo cytotypes are differentiated only to the extent expected of incipient species or geographical populations. Moreover, the sibiling species status previously given to the Bucay cytotype needs be reassessed, there being inadequate analysis from areas in Ecuador where Bucay occurs in sympatry with the standard Cayapa cytotype. No isoenzyme electromorphs were discovered that identified all or mostadult females of any one (cytotype-pure collection.

    Understanding the consequences of polyploidization is a major step towards assessing the importance of this mode of speciation. Most previous studies comparing different cytotypes, however, did so only within a single environment and considered only one group of traits. To take a step further, we need to explore multiple environments and a wide range of traits. The aim of this study was to assess response of diploid and autotetraploid individuals of Knautia arvensis (Dipsacaceae) to two stress conditions, shade or drought. We studied eleven photosynthetic, morphological and fitness parameters of the plants over three years in a common garden under ambient conditions and two types of stress. The results indicate strong differences in performance and physiology between cytotypes in ambient conditions. Interestingly, higher fitness in diploids contrasted with more efficient photosynthesis in tetraploids in ambient conditions. However, stress, especially drought, strongly reduced fitness and disrupted function of the photosystems in both cytotypes reducing the between cytotype differences. The results indicate that drought stress reduced function of the photosynthetic processes in both cytotypes but particularly in tetraploids, while fitness reduction was stronger in diploids. The photosynthesis related traits show higher plasticity in polyploids as theoretically expected, while the fitness related traits show higher plasticity in diploids especially in response to drought. This suggests that between cytotype comparisons need to consider multiple traits and multiple environments to understand the breath of possible responses of different cytotypes to stress. They also show that integrating results based on different traits is not straightforward and call for better mechanistic understanding of the relationships between species photosynthetic activity and fitness. Still, considering multiple environments and multiple species traits is crucial for understanding the

    Full Text Available Progress has been made recently towards the elucidation of phylogenetic relationships among subfamilies and tribes of the Ranunculaceae – the most recent hypothesis was published in 2016 by our team. Although relationships among the 10 tribes of the subfamily Ranunculoideae remain incompletely supported, this hypothesis provides an interesting framework to address the key issue of the ancestral vs. derived nature of a differentiated perianth within the family, and at the level of Ranunculales as a whole. Here, we present ancestral state reconstructions for several perianth characters, such as differentiation into sepals and petals, shape of petals, presence/absence of nectaries, and petaloid or sepaloid aspect of sepals. Characters were scored using the PROTEUS database and optimized on the most recent phylogeny of Ranunculaceae using parsimony and maximum likelihood methods. The results are discussed with regard to recent evo-devo studies focused on identifying genes involved in floral organs identity (the so-called ABC model in Ranunculales.

    2011-01-01

    Cytogeographical variability among 564 plants from 26 populations of Turnera sidoides subsp. pinnatifida in mountain ranges of central Argentina was analysed with meiotic chromosome counts and flow cytometry and is described at regional and local scales. Populations were primarily tetraploids (2n = 4x = 28), although diploid (2n = 2x = 14), hexaploid (2n = 2x = 42), and mixed populations of diploids and triploids (2n = 3x = 21) were also found. Diploids, triploids, and hexaploids were fewer in number and restricted to narrow areas, while tetraploids were the most common and geographically widespread cytotype. Diploids grew at higher altitudes and in colder and wet locations; tetraploids had the broadest ecological spectrum, while hexaploids occurred at the lowest altitudes and in drier conditions. The cytotypes were also spatially segregated at a microgeographical scale. Diploids grew in the piedmont, tetraploids were in the adjacent valley, and in the contact zone of both cytotypes, patches of diploids and triploids were found. At a regional scale, the distribution of the cytotypes may be governed by a combination of ecological and historical variables, while segregation in the contact zone may be independent of the selective environment because the cytotypes are unable to coexist as a result of reproductive exclusion. The role of triploids is also discussed.

    Polyploidy in plants can result in genetic isolation, ecological differences among cytotypes, and, ultimately, speciation. Cytotypes should be sympatric only if they are segregated in an ecological niche or through prezygotic isolation. We tested whether sympatric diploid, tetraploid, and hexaploid ramets of Solidago altissima L. (Asteraceae) differ in their ecological niche. We measured how cytotypes were distributed within habitats, their morphology, and the composition of their communities of herbivorous insects at 10 natural field sites. We also conducted a common garden experiment to confirm whether observed differences in morphology or communities of herbivores were due to cytotype or environmental effects. Diploid ramets often grew in open areas, relatively far from woody plants, and were associated with a high species richness of herbaceous plants, especially grasses. Hexaploids often grew in heavy shading under woody plants where grasses were scarce. Finally, tetraploids usually grew in transition areas between diploids and hexaploids. Hexaploid ramets also were taller than ramets of the other cytotypes and had larger leaves. Two species of insects, the leaf-galling fly Asteromyia carbonifera and the phloem-tapping aphid Uroleucon nigrotuberculatum, were more abundant on hexaploid ramets than on ramets of other cytotypes in the field. When grown in a common garden, however, cytotypes were similar in morphology and communities of herbivores. We conclude that cytotypes of S. altissima differ in their spatial distribution within habitats and that spatial variation in environmental factors influence plant morphology and communities of herbivorous insects.

  17. Chosen aspects of flowering of Ranunculaceae representatives in Poland

    Directory of Open Access Journals (Sweden)

    Bożena Denisow

    2016-04-01

    Full Text Available The family Ranunculaceae consists of numerous widespread species occuring from lowlands to subalpine or alpine zones. In Poland, the species grow in different types of habitats, including xerothermic swards (Adonido-Brachypodietum, Brachypodio- Teucrietum, Thalictro-Salvietum, Seslerio- Scorzoneretum and decidous forests (Tilio- Carpinetum. Many species are popular ornamentals cultivated fro their esthetic value. Ranunculaceans vary remarkably in the phenology of blooming. Among them, there are early spring blooming species like Eranthis hyemalis, Ficaria verna, Isopyrum thalictroides, Anemone nemorosa, A. ranunculoides, and those that start to bloom in autumn, e.g. Aconitum carmichaelli. The overall flowering duration may differ significantly between years – for example, in Anemone sylvestris the disparities reached more than three weeks. The occurrence and the length of each blooming phase may vary considerably between sites, e.g. in Adonis vernalis 10-15-day dissimilarities in the occurrence of blooming stages were recorded. Additionally, the duration of the full blooming stage varied from 10 to 30 days. The diurnal pattern of blooming among Ranunculaceae members was proved to be highly species-specific. Flowers of Aquilegia vulgaris started opening at approx. 5.00 (GMT+2, which was 2-3 hours earlier than those of Adonis vernalis. Significant differences in the diurnal flowering dynamics can be found even in the same genus: flowers of Aconitum lycoctonum began opening at 5.00 (with the peak between 6.00-9.00, while flowers of Aconitum carmichaelii started opening at 8.00 and peaked between 11.00-13.00. The flowering abundance may differ among populations of the same species. The management type was found to have an impact on the individuals’ density of Adonis vernalis occurring in xerothermic grasslands. The control of shrub encashment has already been designated as the factor determining the flowering abundance of Adonis vernalis in

    Intraspecific ploidy-level variation is an important aspect of a species' genetic make-up, which may lend insight into its evolutionary history and future potential. The present study explores this phenomenon in a group of eastern Asian Cardamine species. Plant material was sampled from 59 localities in Japan and Korea, which were used in karyological (chromosome counting) and flow cytometric analyses. The absolute nuclear DNA content (in pg) was measured using propidium iodide and the relative nuclear DNA content (in arbitrary units) was measured using 4,6-diamidino-2-phenylindole fluorochrome. Substantial cytotype diversity was found, with strikingly different distribution patterns between the species. Two cytotypes were found in C. torrentis sensu lato (4x and 8x, in C. valida and C. torrentis sensu stricto, respectively), which displays a north-south geographical pattern in Japan. Hypotheses regarding their origin and colonization history in the Japanese archipelago are discussed. In Korean C. amaraeiformis, only tetraploids were found, and these populations may in fact belong to C. valida. C. yezoensis was found to harbour as many as six cytotypes in Japan, ranging from hexa- to dodecaploids. Ploidy levels do not show any obvious geographical pattern; populations with mixed ploidy levels, containing two to four cytotypes, are frequently observed throughout the range. C. schinziana, an endemic of Hokkaido, has hexa- and octoploid populations. Previous chromosome records are also revised, showing that they are largely based on misidentified material or misinterpreted names. Sampling of multiple populations and utilization of the efficient flow cytometric approach allowed the detection of large-scale variation in ploidy levels and genome size variation attributable to aneuploidy. These data will be essential in further phylogenetic and evolutionary studies.

    The rise of angiosperms has been regarded as a trigger for the Cretaceous revolution of terrestrial ecosystems. However, the timeframe of the rise angiosperm-dominated herbaceous floras (ADHFs) is lacking. Here, we used the buttercup family (Ranunculaceae) as a proxy to provide insights into the rise of ADHFs. An integration of phylogenetic, molecular dating, ancestral state inferring, and diversification analytical methods was used to infer the early evolutionary history of Ranunculaceae. We found that Ranunculaceae became differentiated in forests between about 108–90 Ma. Diversification rates markedly elevated during the Campanian, mainly resulted from the rapid divergence of the non-forest lineages, but did not change across the Cretaceous-Paleogene boundary. Our data for Ranunculaceae indicate that forest-dwelling ADHFs may have appeared almost simultaneously with angiosperm-dominated forests during the mid-Cretaceous, whereas non-forest ADHFs arose later, by the end of the Cretaceous terrestrial revolution. Furthermore, ADHFs were relatively unaffected by the Cretaceous-Paleogene mass extinction. PMID:27251635

  3. Pollinator-mediated selection on nectary depth in Urophysa (Ranunculaceae

    Directory of Open Access Journals (Sweden)

    2016-04-01

    Full Text Available Pollinator-mediated selection has been considered to be one of major factors that shapes the evolution of flowers by matching flowers to their pollinators on traits associated with attraction of pollinators or mechanical fit. The match between nectary depth, which means the length of the tubular structure formed in many plant species to hide the nectary and store nectar, and the mouthparts length of its major nectar-foraging pollinators has been repeatedly demonstrated as an example, because this trait have shown a positive relationship with pollen removal and deposition in experimental manipulations in many synpetalous plants and orchid family. However, it remains unclear how pollinator-mediated selection affects the evolution of nectary depth in choripetalous and actinomorphic flowers, such as most flowers in Ranunculaceae. Here we investigated floral characteristics and pollinators in Urophysa rockii Ulbr. and U. henryi (Oliv. Ulbr., as they are quite the same in habitat, anthesis and morphological characteristics except for nectary depth. Both of these species have flat white sepals and yellow petals each has a spatial structure at the base that contains nectar, but the nectary depth of U. rockii is deeper than that of U. henryi, for the former petals are shortly spurred about 3-4mm in length while the latter are saccate. Meanwhile, the flowers of both species are most frequently visited by Apis cerana, the Chinese honey bee, and one or two species of hover fly, Syrphidae, but only A. cerana was able to forage nectar in U. rockii while all visitors can forage nectar in U. henryi. A. cerana always lands on the center of a flower and projects its proboscis into each petal when its thorax touches anthers and stigmas. The difference between two species is that U. rockii was visited by A. cerana with a higher frequency, longer visiting time per flower and more activities on flowers than U. henryi. Besides, the petal width and its nectary depth of

    Directory of Open Access Journals (Sweden)

    Michaela Sonnleitner

    Full Text Available Reproductive interactions among cytotypes in their contact zones determine whether these cytotypes can co-exist and form stable contact zones or not. In autopolyploids, heteroploid cross-compatibilities might depend on parental ploidy, but tests of this hypothesis in autopolyploid systems with more than two ploidies are lacking. Here, we study Jacobaea carniolica, which comprises diploid, tetraploid, and hexaploid individuals regularly forming contact zones. Seeds obtained from in situ cross-pollinations within and among cytotypes were subjected to DNA flow cytometry and greenhouse germination experiments. Hybrid fitness and parental effects on hybrid fitness were tested with regression models comparing fitness parameters of early life stages. Irrespective of the direction of crosses, seed viability and seedling survival in diploid-polyploid crosses were substantially lower than in tetraploid-hexaploid crosses. In contrast, seedling growth traits indicated neither transgressive character expression nor any selection against hybrid offspring. Congruent with a model of genome dosage effects, these traits differed between reciprocal crosses, especially of diploids and tetraploids, where trait values resembled those of the maternal parent. The strong effect of parental ploidy on offspring fitness in heteroploid crosses may cause contact zones involving exclusively polyploid cytotypes to be less stable over longer terms than those involving diploids and polyploids.

    Full Text Available This paper is a continue of previous work (Новіков 2013 and represents new key for identification of genera from Ranunculaceae family of Western Ukraine (Lviv, Transcarpathian (Zakarpattia, Rivne, Volhynia, Ivano- Frankivsk, Chernivtsi, Ternopil and Khmelnitsk regions (oblasts. This key is consensual and do not corresponds to contemporary taxonomical tendencies in all its points because it is build for non-specialists and/or young scientists which need easy identification tool for their routine field and herbarium work. However, most of modern taxonomical changes and related publications are shortly introduced here and in my previous paper (Новіков 2013. Hence, in present work I suggest that family Ranunculaceae in Western Ukraine is represented by 2 subfamilies, 10 tribes, 22 genera and 102 species. Corresponding consensual taxonomical system is represented. Short characteristics of genera are completed by information about species number and its distribution.

    Polyploidy is widely recognized as a major mechanism of sympatric speciation in plants, yet little is known about its effects on interactions with other organisms. Mycorrhizal fungi are among the most common plant symbionts and play an important role in plant nutrient supply. It remains to be understood whether mycorrhizal associations of ploidy-variable plants can be ploidy-specific. We examined mycorrhizal associations in three cytotypes (2x, 3x, 4x) of the Gymnadenia conopsea group (Orchidaceae), involving G. conopsea s.s. and G. densiflora, at different spatial scales and during different ontogenetic stages. We analysed: adults from mixed- and single-ploidy populations at a regional scale; closely spaced adults within a mixed-ploidy site; and mycorrhizal seedlings. All Gymnadenia cytotypes associated mainly with saprotrophic Tulasnellaceae (Basidiomycota). Nonetheless, both adults and seedlings of diploids and their autotetraploid derivatives significantly differed in the identity of their mycorrhizal symbionts. Interploidy segregation of mycorrhizal symbionts was most pronounced within a site with closely spaced adults. This study provides the first evidence that polyploidization of a plant species can be associated with a shift in mycorrhizal symbionts. This divergence may contribute to niche partitioning and facilitate establishment and co-existence of different cytotypes. © 2013 The Authors. New Phytologist © 2013 New Phytologist Trust.

    Nuclear genome size, as measured by flow cytometry with propidium iodide, was used to investigate the relationships within the genus Ficaria Huds. (Ranunculaceae). For the five diploids the genome size (2C) ranges from 12.5 pg to 23.2 pg. The three tetraploids range from 30.1 for F. chrysocephala (P.D.Sell) Zonn. comb. nov. to 36.2 pg for F. fascicularis.

    Molecular research has shown that Ficaria (Ranunculaceae) is not closely related to Ranunculus. In this study I regard the genus as monospecific with 7 subspecies. It is an arbitrary choice to regard these taxa as species or subspecies. In most of the recent literature a choice has been made for the latter and this is followed here. The type is Ficaria verna (≡ Ranunculus ficaria). Benson (1954: 369)1 was the first to designate a lectotype: Herb. Linn. 715.12 (LINN) without provenance, but mo...

  11. Specific duplication and dorsoventrally asymmetric expression patterns of Cycloidea-like genes in zygomorphic species of Ranunculaceae.

    Directory of Open Access Journals (Sweden)

    Florian Jabbour

    Full Text Available Floral bilateral symmetry (zygomorphy has evolved several times independently in angiosperms from radially symmetrical (actinomorphic ancestral states. Homologs of the Antirrhinum majus Cycloidea gene (Cyc have been shown to control floral symmetry in diverse groups in core eudicots. In the basal eudicot family Ranunculaceae, there is a single evolutionary transition from actinomorphy to zygomorphy in the stem lineage of the tribe Delphinieae. We characterized Cyc homologs in 18 genera of Ranunculaceae, including the four genera of Delphinieae, in a sampling that represents the floral morphological diversity of this tribe, and reconstructed the evolutionary history of this gene family in Ranunculaceae. Within each of the two RanaCyL (Ranunculaceae Cycloidea-like lineages previously identified, an additional duplication possibly predating the emergence of the Delphinieae was found, resulting in up to four gene copies in zygomorphic species. Expression analyses indicate that the RanaCyL paralogs are expressed early in floral buds and that the duration of their expression varies between species and paralog class. At most one RanaCyL paralog was expressed during the late stages of floral development in the actinomorphic species studied whereas all paralogs from the zygomorphic species were expressed, composing a species-specific identity code for perianth organs. The contrasted asymmetric patterns of expression observed in the two zygomorphic species is discussed in relation to their distinct perianth architecture.

    The constituents of Cimicifuga plants have been extensively investigated, and the principal metabolites are 9,19-cyclolanostane triterpenoid glycosides, which are distributed widely in Cimicifuga plants, but not in other members of the Ranunculaceae family, and are considered to be characteristics of the Cimicifuga genus. This type of triterpenoid glycoside possesses several important biological activities. More than 120 cycloartane triterpene glycosides have been isolated from Cimicifuga simplex Wormsk. The aim of this review article is to summarize all the major findings based on the available scientific literatures on C. simplex, with a focus on the identified 9,19-cyclolanostane triterpenoid glycosides. Biological studies of cycloartane triterpene glycosides from Cimicifuga spp. are also discussed. Copyright © 2015 China Pharmaceutical University. Published by Elsevier B.V. All rights reserved.

    Apomixis in Crataegus is primarily aposporous and requires pollination. The embryo sac is of the Polygonum type. A combination of meiotically unreduced embryo sacs with apparently reduced pollen would violate the usual requirement for a 2 : 1 ratio of maternal to paternal contributions to the endosperm. We therefore investigated the origin of endosperm in seeds of sexual diploids and apomictic polyploids of the sister genera Crataegus and Mespilus. Flow-cytometric DNA measurements from embryo and endosperm in mature seeds were converted to ploidy levels using leaf-tissue information. The diploids had triploid endosperm. In c. 60% of seed from polyploids, one sperm apparently contributes to the endosperm, while 25% or more may involve two sperm. Additional results suggest that trinucleate central cells also occur. Fertilization of meiotically unreduced eggs is indicated. The ratio of maternal to paternal contributions to the endosperm in these apomictic Crataegus is not constrained to 2 : 1. They thus resemble some Sorbus (Pyreae) and very distantly related Ranunculus (Ranunculaceae). It is suggested that Paspalum (Poaceae) may have similarly flexible endosperm ploidy levels.

    Full Text Available The five native and naturalised species of Ranunculus L. and Peltocalathos Tamaru (Ranunculaceae: Ranunculeae from southern Africa are reviewed, with full descriptions and nomenclature, taxonomic history, ecological notes, and distribution data. All species are illustrated. Peltocalathos, a monotypic genus based on R. baurii MacOwan, has been overlooked in the regional literature until now. The new name R. dregei J.C.Manning & Goldblatt is proposed as a replacement name for the later homonym R. meyeri Harv., non Lowe. We conclude that the poorly known R. capensis Thunb. represents juvenile forms of the widespread and variable R. multifidus Forssk. and we synonymise the name, along with the three trivial epithets R. pinnatus var. hermannii DC., R. pubescens var. glabrescens Burtt Davy and R. pubescens var. harveyanus Burtt Davy, which have been overlooked in the recent literature. Based on number (mostly < 40 achenes per head and size (mostly 1.2–1.8 mm long of achenes, we conclude that the southern African material of the aquatic species recently re-identified as R. rionii Lagger is more appropriately treated as R. trichophyllus Chaix.

    Despite the importance of assessing the stability of epigenetic variation in non-model organisms living in real-world scenarios, no studies have been conducted on the transgenerational persistence of epigenetic structure in wild plant populations. This gap in knowledge is hindering progress in the interpretation of natural epigenetic variation. By applying the methylation-sensitive amplified fragment length polymorphism (MSAP) technique to paired plant-pollen (i.e., sporophyte-male gametophyte) DNA samples, and then comparing methylation patterns and epigenetic population differentiation in sporophytes and their descendant gametophytes, we investigated transgenerational constancy of epigenetic structure in three populations of the perennial herb Helleborus foetidus (Ranunculaceae). Single-locus and multilocus analyses revealed extensive epigenetic differentiation between sporophyte populations. Locus-by-locus comparisons of methylation status in individual sporophytes and descendant gametophytes showed that ~75% of epigenetic markers persisted unchanged through gametogenesis. In spite of some epigenetic reorganization taking place during gametogenesis, multilocus epigenetic differentiation between sporophyte populations was preserved in the subsequent gametophyte stage. In addition to illustrating the efficacy of applying the MSAP technique to paired plant-pollen DNA samples to investigate epigenetic gametic inheritance in wild plants, this paper suggests that epigenetic differentiation between adult plant populations of H. foetidus is likely to persist across generations.

    Full Text Available Based on a study of a perennial herb Anemone patens L. (Ranunculaceae in a variety of natural habitats in Saskatchewan, Canada, eight life stages (seed, seedling, juvenile, immature, vegetative, generative, subsenile, and senile are distinguished and characterized in detail. The species ontogenetic growth patterns are investigated. A. patens has a long life cycle that may last for several decades which leads to the formation of compact clumps. The distribution and age of clumps vary substantially in different environments with different levels of disturbance. The plant ontogeny includes the regular cycle with reproduction occurring through seeds. There is an optional subsenile vegetative disintegration at the end of the life span. The following variations in the life cycle of A. patens are identified: with slower development in young age, with an accelerated development, with omission of the generative stage, with retrogression to previous life stages in mature age, and with vegetative dormancy. The range of variations in the life cycle of A. patens may play an important role in maintaining population stability in different environmental conditions and management regimes.

  17. The First Comprehensive Phylogeny of Coptis (Ranunculaceae and Its Implications for Character Evolution and Classification.

    Full Text Available Coptis (Ranunculaceae contains 15 species and is one of the pharmaceutically most important plant genera in eastern Asia. Understanding of the evolution of morphological characters and phylogenetic relationships within the genus is very limited. Here, we present the first comprehensive phylogenetic analysis of the genus based on two plastid and one nuclear markers. The phylogeny was reconstructed using Bayesian inference, as well as maximum parsimony and maximum likelihood methods. The Swofford-Olsen-Waddell-Hillis and Bayesian tests were used to assess the strength of the conflicts between traditional taxonomic units and those suggested by the phylogenetic inferences. Evolution of morphological characters was inferred using Bayesian method to identify synapomorphies for the infrageneric lineages. Our data recognize two strongly supported clades within Coptis. The first clade contains subgenus Coptis and section Japonocoptis of subgenus Metacoptis, supported by morphological characters, such as traits of the central leaflet base, petal color, and petal shape. The second clade consists of section Japonocoptis of subgenus Metacoptis. Coptis morii is not united with C. quinquefolia, in contrast with the view that C. morii is a synonym of C. quinquefolia. Two varieties of C. chinensis do not cluster together. Coptis groenlandica and C. lutescens are reduced to C. trifolia and C. japonica, respectively. Central leaflet base, sepal shape, and petal blade carry a strong phylogenetic signal in Coptis, while leaf type, sepal and petal color, and petal shape exhibit relatively higher levels of evolutionary flexibility.

    East Asia is characterized by high levels of species diversity and endemism. However, the biogeographical patterns and processes underlying the distribution of biodiversity within the area are still poorly known. In this study, we used plastid (matK, trnL-F, and trnH-psbA) and nuclear (ITS) DNA sequences to investigate the historical biogeography of Dichocarpum (Ranunculaceae), an eastern Asian endemic genus throughout warm-temperate and subtropical forests of the area. Phylogenetic analyses strongly support Dichocarpum as monophyletic, which contains two major clades. Clade I corresponds to section Hutchinsonia, and clade II includes sections Dichocarpum and Fargesia. Section Dichocarpum and its subsections Dalzielia and Dichocarpum are not recognized as monophyletic. Our results suggest that the most recent common ancestor of Dichocarpum occurred in central China and Japan in the earliest Early Miocene, and thus support an ancient vicariance event between Japan and China. Within mainland China, three migrations at the species level were hypothesized to explain the expansion of Dichocarpum from central China to southeastern Yunnan, Hengduan mountains, and eastern Himalaya. These migration events occurred in the Late Miocene to Early Pliocene, which may be associated with the uplift of the southeastern Qinghai-Tibetan Plateau and accordingly the expansion of subtropical forests in China around that period. A migration or dispersal from central China to Taiwan was inferred in the Early Pleistocene, which supports the close floristic affinity between Taiwan and mainland China. This study contributes to our knowledge on the historical biogeography of plants in eastern Asia. Copyright © 2016 Elsevier Inc. All rights reserved.

  19. Pollination and floral biology of Adonis vernalis L. (Ranunculaceae – a case study of threatened species

    Full Text Available Although the knowledge of pollination systems of rare and threatened species is one of the principles for development of optimal conservation and management strategies, the data about their pollination requirements are scarce or incomplete. Different problems are listed (xerothermic habitat disappearance, overgrowing of patches, plant biology i.e., slow plant growth, problems with seed germination among the possible causes of Adonis vernalis being threatened, but until now no consideration was given to the flowering biology and pollination. The observations of flowering biology of A. vernalis (Ranunculaceae, a clonal species, were conducted in an out-of-compact-range population, in the Lublin Upland, Poland (51°18'55" N, 22°38'21" E, in 2011–2013. The reproductive potential of A. vernalis is related to the population age structure, pollination syndrome, and breeding system. The flowers exhibit incomplete protogyny. The dichogamy function is supported by different (biological, morphological mechanisms. Stigma receptivity occurred about one day before anthers started shedding self-pollen, and pollen viability was increasing gradually during the flower life-span (66.3% in distal anthers vs. 77.3% in proximal. The decrease in pollen production and in pollen viability coincided with the lowest degree of seed set, irrespective of the pollination treatment. Pollen vectors are necessary for efficient pollination, as the proportion of pistils setting fruits after open pollination (41–82.1% was significantly higher compared to spontaneous self-pollination (only 5.5–12.3%. The pollination requirements together with pollen/ovule ratio (P/O = 501 indicate a facultative xenogamous breeding system in A. vernalis. Therefore, in the conditions of the global lack of pollinators, improper pollination may weaken the population by leading to a decrease in the proportion of recombinants, and in addition to other factors, may accelerate extinction of small A

    Full Text Available Polyploid species generally occupy harsher habitats (characterized by cold, drought and/or high altitude than diploids, but the converse was observed for Chamerion angustifolium, in which diploid plants generally inhabit higher altitudes than their polyploid derivatives. Plants at high altitudes may experience cold-induced water stress, and we therefore examined the physiological responses of diploid and hexaploid C. angustifolium to water stress to better understand the ecological differentiation of plants with different ploidy levels. We conducted a common garden experiment by subjecting seedlings of different ploidy levels to low, moderate and severe water stress. Fourteen indicators of physiological fitness were measured, and the anatomical characteristics of the leaves of each cytotype were determined. Both cytotypes were influenced by drought, and diploids exhibited higher fitness in terms of constant root:shoot ratio (R:S ratio and maximum quantum yield of PSⅡ (Fv/Fm, less reduced maximal photosynthetic rate (Amax, transpiration rate (E, intercellular CO2 concentration (Ci and stomatal conductance (gs, and higher long-term water use efficiency (WUEL under severe water stress than did hexaploids. Analysis of leaf anatomy revealed morphological adjustments for tolerating water deficiency in diploids, in the form of closely packed mesophyll cells and small conduits in the midvein. Our results indicate that diploid C. angustifolium is more tolerant of drought than hexaploid plants, ensuring the successful survival of the diploid at high altitudes. This eco-physiological divergence may facilitate the species with different cytotypes to colonize new and large geographic ranges with heterogeneous environmental conditions.

    Full Text Available In the present paper we provide the first contribution to the knowledge of the flower-visiting insect assemblages of the alpine plant species Callianthemum kernerianum Freyn ex A. Kerner (Ranunculaceae. This focal plant species was selected since it is a steno-endemic and critically endangered species belonging to the IUCN red-list. Fifteen taxa were recorded, among which very few are true pollinators, whereas all the others can be considered only indirect pollinators. The peculiar phenology of the plant and the harsh habitat conditions in which it grows probably affect the richness and abundance of flower-visiting insects as well as of true pollinators. This could be the reason for this plant to be a self-compatible species.

  5. Nectar yeasts in the tall Larkspur Delphinium barbeyi (Ranunculaceae and effects on components of pollinator foraging behavior.

    Directory of Open Access Journals (Sweden)

    Robert N Schaeffer

    Full Text Available Microorganisms frequently colonize the nectar of angiosperm species. Though capable of altering a suite of traits important for pollinator attraction, few studies exist that test the degree to which they mediate pollinator foraging behavior. The objective of our study was to fill this gap by assessing the abundance and diversity of yeasts associated with the perennial larkspur Delphinium barbeyi (Ranunculaceae and testing whether their presence affected components of pollinator foraging behavior. Yeasts frequently colonized D. barbeyi nectar, populating 54-77% of flowers examined depending on site. Though common, the yeast community was species-poor, represented by a single species, Metschnikowia reukaufii. Female-phase flowers of D. barbeyi were more likely to have higher densities of yeasts in comparison to male-phase flowers. Pollinators were likely vectors of yeasts, as virgin (unvisited flowers rarely contained yeasts compared to flowers open to pollinator visitation, which were frequently colonized. Finally, pollinators responded positively to the presence of yeasts. Bombus foragers both visited and probed more flowers inoculated with yeasts in comparison to uninoculated controls. Taken together, our results suggest that variation in the occurrence and density of nectar-inhabiting yeasts have the potential to alter components of pollinator foraging behavior linked to pollen transfer and plant fitness.

    2012-08-01

    Full Text Available Abstract Background Hybridisation is presumed to be an important mechanism in plant speciation and a creative evolutionary force often accompanied by polyploidisation and in some cases by apomixis. The Potentilla collina group constitutes a particularly suitable model system to study these phenomena as it is morphologically extensively variable, exclusively polyploid and expresses apomixis. In the present study, the alpine taxon Potentilla alpicola has been chosen in order to study its presumed hybrid origin, identify underlying evolutionary processes and infer the discreteness or taxonomic value of hybrid forms. Results Combined analysis of AFLP, cpDNA sequences and ploidy level variation revealed a hybrid origin of the P. alpicola populations from South Tyrol (Italy resulting from crosses between P. pusilla and two cytotypes of P. argentea. Hybrids were locally sympatric with at least one of the parental forms. Three lineages of different evolutionary origin comprising two ploidy levels were identified within P. alpicola. The lineages differed in parentage and the complexity of the evolutionary process. A geographically wide-spread lineage thus contrasted with locally distributed lineages of different origins. Populations of P. collina studied in addition, have been regarded rather as recent derivatives of the hexaploid P. argentea. The observation of clones within both P. alpicola and P. collina suggested a possible apomictic mode of reproduction. Conclusions Different hybridisation scenarios taking place on geographically small scales resulted in viable progeny presumably stabilised by apomixis. The case study of P. alpicola supports that these processes played a significant role in the creation of polymorphism in the genus Potentilla. However, multiple origin of hybrids and backcrossing are considered to produce a variety of evolutionary spontaneous forms existing aside of reproductively stabilised, established lineages.

    Absence of petals, or being apetalous, is usually one of the most important features that characterizes a group of flowering plants at high taxonomic ranks (i.e., family and above). The apetalous condition, however, appears to be the result of parallel or convergent evolution with unknown genetic causes. Here we show that within the buttercup family (Ranunculaceae), apetalous genera in at least seven different lineages were all derived from petalous ancestors, indicative of parallel petal losses. We also show that independent petal losses within this family were strongly associated with decreased or eliminated expression of a single floral organ identity gene, APETALA3-3 (AP3-3), apparently owing to species-specific molecular lesions. In an apetalous mutant of Nigella, insertion of a transposable element into the second intron has led to silencing of the gene and transformation of petals into sepals. In several naturally occurring apetalous genera, such as Thalictrum, Beesia, and Enemion, the gene has either been lost altogether or disrupted by deletions in coding or regulatory regions. In Clematis, a large genus in which petalous species evolved secondarily from apetalous ones, the gene exhibits hallmarks of a pseudogene. These results suggest that, as a petal identity gene, AP3-3 has been silenced or down-regulated by different mechanisms in different evolutionary lineages. This also suggests that petal identity did not evolve many times independently across the Ranunculaceae but was lost in numerous instances. The genetic mechanisms underlying the independent petal losses, however, may be complex, with disruption of AP3-3 being either cause or effect.

  12. Genomic Resources of Three Pulsatilla Species Reveal Evolutionary Hotspots, Species-Specific Sites and Variable Plastid Structure in the Family Ranunculaceae

    Directory of Open Access Journals (Sweden)

    2015-09-01

    Full Text Available Background: The European continent is presently colonized by nine species of the genus Pulsatilla, five of which are encountered only in mountainous regions of southwest and south-central Europe. The remaining four species inhabit lowlands in the north-central and eastern parts of the continent. Most plants of the genus Pulsatilla are rare and endangered, which is why most research efforts focused on their biology, ecology and hybridization. The objective of this study was to develop genomic resources, including complete plastid genomes and nuclear rRNA clusters, for three sympatric Pulsatilla species that are most commonly found in Central Europe. The results will supply valuable information about genetic variation, which can be used in the process of designing primers for population studies and conservation genetics research. The complete plastid genomes together with the nuclear rRNA cluster can serve as a useful tool in hybridization studies. Methodology/principal findings: Six complete plastid genomes and nuclear rRNA clusters were sequenced from three species of Pulsatilla using the Illumina sequencing technology. Four junctions between single copy regions and inverted repeats and junctions between the identified locally-collinear blocks (LCB were confirmed by Sanger sequencing. Pulsatilla genomes of 120 unique genes had a total length of approximately 161–162 kb, and 21 were duplicated in the inverted repeats (IR region. Comparative plastid genomes of newly-sequenced Pulsatilla and the previously-identified plastomes of Aconitum and Ranunculus species belonging to the family Ranunculaceae revealed several variations in the structure of the genome, but the gene content remained constant. The nuclear rRNA cluster (18S-ITS1-5.8S-ITS2-26S of studied Pulsatilla species is 5795 bp long. Among five analyzed regions of the rRNA cluster, only Internal Transcribed Spacer 2 (ITS2 enabled the molecular delimitation of closely-related Pulsatilla

    2017-04-01

    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.

    2003-01-01

    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.

    A left minor fissure (LMF) has been described anatomically as being present in 8%-18% of left lungs. Analogous to the right minor fissure (RMF), the LMF separates the anterior segment of the left upper lobe from the lingula. Two thousand consecutive normal radiographic examinations of the adult chest (posteroanterior, left lateral views with the subjects in the erect position) were reviewed prospectively. A definite LMF was identified in 32 of the subjects (1.6%). The fissure was dome-shaped (convex superior) on at least one projection in 26 (81%) of 32 subjects. The position of the LMF was usually more cephalad than that of the RMF (25 of 31 subjects, or 81%). The lateral end of the LMF was usually superior to the medial end (25 of 32; 78%) and rarely inferior to the medial end (three of 32; 9%). The LMF infrequently was horizontal (four of 32; 12%). In a number of additional patients whose control chest radiographs showed no evidence of an LMF, subsequent radiographs revealed an LMF outlined by active pulmonary or pleural disease.

  20. BOOK REVIEW: Minority Games

    Science.gov (United States)

    Metzler, R.

    2005-02-01

    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

    Minority providers are more likely to practice in underserved areas with minority populations. Currently the representation of minorities in healthcare professions is less than that of the United States population. More research is needed to examine specific variables associated with educational success of minority students. The purpose of this study is to examine, and increase the understanding of, current factors that influence success among ethnic and minority nursing students. The revised Minority Student Nurse Questionnaire (MSNQ) was utilized for this study with a sample of 31 students from 2 entry-level nursing programs in the Midwest. Minority students were slightly older than traditional college students and consisted of African-American Black, Native (American) Indian, Asian, Hispanic/Latino, and Hawaiian. Students reported multiple factors that influenced their higher education experience. Academic services and cultural organizations were available, free, but were used by less than half of the students. Several sources of financial assistance are important, including scholarships, federal subsidized and unsubsidized loans, and grants. Students most strongly disagreed with the statement that 'the number of minorities in this program is representative of the number of minorities overall.' Students felt that several services were supportive and helpful strategies for success. Although progress has been made to improve success of minority students, numbers continue to lag between demographic population overall.

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

    Science.gov (United States)

    Skutnabb-Kangas, Tove; Phillipson, Robert

    1996-07-01

    "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.

  11. Minors and Sexting: Legal Implications.

    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. © 2016 American Academy of Psychiatry and the Law.

  12. Dictionary of minor planet names

    1997-01-01

    Until recently, minor planet name citations were scattered in the astronomical literature, and the origin of many names remained obscure In 1988 the IAU Commission 20 established a study group to elucidate the meanings of asteroid names Later on the author continued in collecting and indexing all new relevant data This book contains the names, and their meanings, of all - as yet 5252 - named minor planets It informs about the discoverers as well as the circumstances of the discovery of all 7041 minor planets that were numbered up to June 1996 In addition to being of practical value for identification purposes, the collection provides a most interesting historical insight into the work of those astronomers who over two centuries vested their affinities in a rich and colourful variety of ingenious names, from heavenly goddesses to more prosaic constructions This third, revised and enlarged edition comprises about 40% more information than was provided with the first one of 1992

  13. Bussing of Ethnic Minority Children

    DEFF Research Database (Denmark)

    2015-01-01

    This article concerns the rights and duties of ethnic minority children in education in Denmark. More specifically, it discusses the policy of compulsory bussing of ethnic minority children based on language screenings that was legalized by the Danish Parliament in 2005. The policy concerns...... the meeting between citizens with an ethnic minority background and the Danish state, represented by welfare institutions, in this case public elementary schools, and changes the character of this meeting for the individuals involved. In the article, I concentrate on two rights at stake in this meeting......, namely the right to free choice of school and the right – or duty? – to obtain more-equal opportunities in education. The policy creates a dilemma between these two rights and furthermore between a right and a duty to obtain better education results. The article discusses whether the bussing policy may...

  14. Happiness and Sexual Minority Status.

    2016-10-01

    We used logistic regression on nationally representative data (General Social Survey, N = 10,668 and N = 6680) to examine how sexual minority status related to happiness. We considered two central dimensions of sexual minority status-sexual behavior and sexual identity. We distinguished between same-sex, both-sex, and different-sex-oriented participants. Because individuals transition between sexual behavior categories over the life course (e.g., from both-sex partners to only same-sex partners) and changes in sexual minority status have theoretical associations with well-being, we also tested the associations of transitions with happiness. Results showed that identifying as bisexual, gay, or lesbian, having both male and female partners since age 18, or transitioning to only different-sex partners was negatively related to happiness. Those with only same-sex partners since age 18 or in the past 5 years had similar levels of happiness as those with only different-sex partners since age 18. Additional tests showed that the majority of these happiness differences became non-significant when economic and social resources were included, indicating that the lower happiness was a product of structural and societal forces. Our findings clearly and robustly underscored the importance of taking a multi-faceted approach to understanding sexuality and well-being, demonstrating that not all sexual minority groups experience disadvantaged happiness. Our study calls for more attention to positive aspects of well-being such as happiness in examinations of sexual minorities and suggests that positive psychology and other happiness subfields should consider the role of sexual minority status in shaping happiness.

  3. Spies in the minority game

    Science.gov (United States)

    2008-01-01

    We study the effects of the existence of another type of agents, called spies, in the minority game (MG). Unlike the normal agents in the MG, the spies do not carry any strategy. Instead, they decide their action by scouting some normal agents and take the minority action of the spied group. For a few spies and when there is useful information in the normal agents’ actions, the spies can avoid the crowd effect of the normal agents and win more readily. When information becomes less useful and when more spies are present, the spies’ crowd effect hurts the success rate of the spies themselves, and the normal agents could have a higher success rate than the spies. More spies actually assist more normal agents to win, as the spies also provide more winning quotas. This leads to a nonmonotonic behavior in the total success rate of the population as a function of the fraction of spies.

    Viral hepatitis continues as an important public health concern in the United States. Available data indicate that acute and chronic viral hepatitis remains an important cause of morbidity and mortality in this country despite the availability of immunization for hepatitis A and B and pharmacologic therapy for chronic hepatitis B and C. Minority populations within the United States are disproportionately affected by acute and chronic viral hepatitis. Many diseases, for example, Barrett's esophagus, affect ethnic groups differently. Viral hepatitis A, B, and C may demonstrate ethnic variation with regard to their epidemiology, natural history, clinicopatholgic findings, complications, and treatment outcomes. This report will review the literature regarding these areas in hepatitis A, B, and C among the African American, Hispanic American, and Native American populations of the United States.

Let A[N] be an arbitrary graded overdomain of A generated as an A-algebra by N placed in degree 1. Let A[M] be the subalgebra generated by M. Set C:=Proj(A[M]) and r:=dim C. Form the (closed) subset W of Spec(A) of primes p where A[N]_p is not a finitely generated module over A[M]_p, and denote the preimage of W in C by E. We prove this: (1) dim E=r-1 if either (a) N is free and A[N] is the symmetric algebra, or (b) W is nonempty and A is universally catenary, and (2) E is equidimensional if (a) holds and A is universally catenary.

    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, pSexual 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.

    2016-01-01

    Introduction A growing body of evidence reveals higher rates of tobacco use among sexual minority populations relative to non-minority (“straight”) populations. This study seeks to more fully characterize this disparity by examining tobacco use by distinct sexual identities and gender to better understand patterns of: (1) cigarette smoking and smoking history; and (2) use of other tobacco products including cigars, pipes, hookah, e-cigarettes, and smokeless tobacco. Methods Data from the 2012–2013 National Adult Tobacco Survey, a random-digit dialed landline and cellular telephone survey of U.S. adults aged ≥18 years, were analyzed in 2014. A sexual minority category was created by combining gay, lesbian, and bisexual responses, along with those who selected an option for other non-heterosexual identities. Results Smoking prevalence was higher among sexual minority adults (27.4%) than straight adults (17.3%). Cigarette smoking was particularly high among bisexual women (36.0%). Sexual minority women started smoking and transitioned to daily smoking earlier than their straight peers. Use of other tobacco products was higher among sexual minority women: prevalence of e-cigarette (12.4%), hookah (10.3%), and cigar use (7.2%) was more than triple that of their straight female peers (3.4%, 2.5%, and 1.3%, respectively). Likewise, prevalence of sexual minority men’s e-cigarette (7.9%) and hookah (12.8%) use exceeded that of straight men (4.7% and 4.5%, respectively). Conclusions Tobacco use is significantly higher among sexual minority than straight adults, particularly among sexual minority women. These findings underscore the importance of tobacco control efforts designed to reach sexual minorities and highlight the heterogeneity of tobacco use within this population. PMID:26526162

    Bruce, Douglas; Harper, Gary W.; Bauermeister, Jose A.

    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.

    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. 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. Experience of stigma was associated with internalized homophobia (β=.138, pinternalized homophobia partially mediated experience's effects on major depression (β=.773, OR=2.167, pinternalized homophobia (β=.418, pinternalized 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. 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.

    Full Text Available The aim of this paper is to present, from penological aspect, the involvement and structure of recidivism at minors with mental deficiency within the whole area of juvenile criminality in Macedonia. The research covers 62 subjects who pay the penalty in juvenile penitentiary or institutional measure directing to correctional institution for minors. Of the total number of minors who hold one of the above-mentioned sanctions, minors with lower average IQ are presented with 56.4%. The shown involvement is in penological terms (refers to minors who hold institutional measure correctional institution for minors or penalty - juvenile penitentiary which does not mean that this category of juvenile delinquents participate in such percent in the total number of reported, accused and convicted minors. According to the research results it can be concluded that falling behind in intellectual development is an indicator for delinquent behavior but in no case it can be crucial or the most important factor for criminality. Of the total number of juvenile delinquents with intellectual deficit, 80% are repeat offenders in criminal legal sense. It is of great concern that 56% of the under average juvenile delinquents defied the law for the first time before the age of 14 years that is as children.

    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.

    2014-01-01

    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.

    Full Text Available The paper analyses the Minority Game and focuses on analysis and computational modelling of several variants (variable payoff, coalition-based and ternary voting of Minority Game using UAREI (User-Action-Rule-Entities-Interface model. UAREI is a model for formal specification of software gamification, and the UAREI visual modelling language is a language used for graphical representation of game mechanics. The URAEI model also provides the embedded executable modelling framework to evaluate how the rules of the game will work for the players in practice. We demonstrate flexibility of UAREI model for modelling different variants of Minority Game rules for game design.

    2013-02-01

    To test Music Marker Theory (MMT) positing that early adolescents' preferences for nonmainstream types of popular music indicate concurrent and later minor delinquency. MMT was tested in a 4-year longitudinal study (n = 309). The results showed that early fans of different types of rock (eg, rock, heavy metal, gothic, punk), African American music (rhythm and blues, hip-hop), and electronic dance music (trance, techno/hardhouse) showed elevated minor delinquency concurrently and longitudinally. Preferring conventional pop (chart pop) or highbrow music (classic music, jazz), in contrast, was not related to or was negatively related to minor delinquency. Early music preferences emerged as more powerful indicators of later delinquency rather than early delinquency, indicating that music choice is a strong marker of later problem behavior. The mechanisms through which music preferences are linked to minor delinquency are discussed within the framework of MMT.

    Full Text Available Inside the vast array characterizing the phenomenon of migration, in this paper we chose to focus our analysis on a unique and extremely delicate category: the minor immigrants. The main objective is to highlight the heterogeneity of juvenile migratory phenomenon, achieving a prospective of analyses which focuses not only on international law aimed at protecting minors but also on the flaws of European systems which ignore too often the importance of the superior interests of the child. Mainly the Convention on the Rights of the Child, signed in New York in 1959, provides a generalized protection of minor figure and it represents the legal basis for all rules directed towards children and thus to minor immigrants.

    Rostosky, Sharon Scales; Riggle, Ellen Db

    2017-02-01

    Same-sex relationships are stigmatized in a culture that privileges heterosexual relationships. This stigma creates minority stress in the lives of same-sex couples. We review current research on minority stress and same-sex relationships using an ecological framework to conceptualize the sources of minority stress that impact couples. Findings from this review suggest a need for research that moves conceptually and methodologically beyond a focus on the individual to a focus on the dyad and the interpersonal, institutional, and cultural sources of minority stress that affect couple relationships. Focusing on the strengths and resiliencies of same-sex couples will also extend the research. Creating effective dyadic interventions will promote the health and well-being of same-sex couples and their families. Copyright © 2016 Elsevier Ltd. All rights reserved.

  16. Zhang Tianlu -- expert on China's minority population.

    Science.gov (United States)

    Li, G

    1991-10-01

    Zhang Tianlu, a professor at the Population Institute of Beijing College of Economics began research on the minority populations of China in the 1950s when he was a geography professor at the Central Institute of Minority Nationalities. During the cultural revolution, the government forced him and his family to work on a farm for 3 years in Hubei Province. He took some of the materials and data he collected during his tenure at the Central Institute instead of bringing his family's property and books. At night, he studied the minority populations because he believed his research would someday be valuable. In the early 1980s, the government transferred him to Beijing College of Economics to allow him to focus on the minority populations of China. He has since spent much time conducting anthropological field work to interview people from the 22 minority populations. He studied their population, economic, and educational status, marriage and family customs, and the effect these customs have had on fertility. The people received him well. He also took the opportunity while conducting his surveys to inform the people about population and family planning by pointing out the link between population and economic development. He informed them that their rapid population growth does not contribute to their prosperity. Between 1981-91, Dr. Zhang has authored 6 monographs such as Changes in Tibetan population and China's Muslim Population. The monograph Ethnic Demography was the 2nd monograph in the world on ethnic population research. He has also helped publish the only journal in the world on minority populations--Ethnic Population. In 1991, he was the chief investigator for a UNFPA funded and State Education Commission sponsored study on minority populations.

  17. We Can Recruit Minorities Into The Geosciences

    Science.gov (United States)

    O'Connell, S.

    2011-12-01

    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.

  18. Minority stress, psychosocial resources, and psychological distress among sexual minority breast cancer survivors.

    Few studies have examined unique factors predicting psychological distress among sexual minority (i.e., lesbian and bisexual) women postbreast cancer diagnosis. The present study assessed the association of minority stress and psychosocial resource factors with depression and anxiety symptoms among sexual minority breast cancer survivors. Two hundred one sexual minority women who had ductal carcinoma in situ or Stage I-IV breast cancer participated in this study through the Love/Avon Army of Women. Self-report questionnaires were used to assess demographic and clinical factors, minority stress factors (discrimination, minority identity development, outness), psychosocial resources (resilience, social support), and psychological distress (anxiety and depression). These factors were included in a structural equation model, testing psychosocial resources as mediators between minority stress and psychological distress. There were no significant differences noted between lesbian and bisexual women. The final structural equation model demonstrated acceptable fit across all sexual minority women, χ2 = 27.83, p > .05; confirmatory fit index = 0.97, root-mean-square error of approximation = 0.04, Tucker-Lewis index = 0.93. The model accounted for significant variance in psychological distress (56%). Examination of indirect effects confirmed that exposure to discrimination was associated with distress via association with resilience. Factors unique to sexual minority populations, such as minority stress, may be associated with higher rates of psychological distress among sexual minority breast cancer survivors. However, presence of psychosocial resources may mediate relationships with distress in this population; enhancement of resilience, in particular, could be an aim of psychological intervention.

  19. Health concerns of sexual minority adolescent girls.

    Science.gov (United States)

    Brown, Joanna D; Melchiono, Maurice W

    2006-08-01

    The goal of this article is to provide an overview of up-to-date health information about sexual minority female youth so that healthcare practitioners can better serve their healthcare needs. Sexual minority adolescent girls may follow diverse sexual developmental trajectories. Many in this population are quite healthy, but some may be disproportionately vulnerable to health risks, perhaps because of the stigma associated with minority sexuality in society. If sexually active, girls in this population often have sex with boys as well as girls and confront risks attendant with sex with both genders. They may demonstrate fluidity in their sexual identity as they move through adolescence. Data suggest that sexual minority adolescent girls are more likely to smoke cigarettes, drink alcohol, or use illicit drugs compared with girls who are heterosexual. They may be more likely to be victims of violence or victimization or to be depressed or suicidal. Sexual minority adolescent girls may be quite resilient, but they face a range of possible adverse health risks. Healthcare practitioners should keep their health issues in mind so they can offer healthcare and counseling that is sensitive, comprehensive, and appropriate.

  20. Atmospheric Solar Heating in Minor Absorption Bands

    Science.gov (United States)

    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.

    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?

    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.

    Articular cartilage is a connective tissue consisting of a specialized extracellular matrix (ECM) that dominates the bulk of its wet and dry weight. Type II collagen and aggrecan are the main ECM proteins in cartilage. However, little attention has been paid to less abundant molecular components......, especially minor collagens, including type IV, VI, IX, X, XI, XII, XIII, and XIV, etc. Although accounting for only a small fraction of the mature matrix, these minor collagens not only play essential structural roles in the mechanical properties, organization, and shape of articular cartilage, but also...... fulfil specific biological functions. Genetic studies of these minor collagens have revealed that they are associated with multiple connective tissue diseases, especially degenerative joint disease. The progressive destruction of cartilage involves the degradation of matrix constituents including...

  9. Words and Deeds: Presidential Discussion of Minority Health, Public Policies, and Minority Perceptions.

    Science.gov (United States)

    Gillion, Daniel Q

    2017-10-01

    What are the different rhetorical approaches presidents used to address minority health inequality? More importantly, how have the efforts of presidents impacted minorities' perceptions of health? I offer a historical perspective that describes the three major periods of presidential engagement in discussions of minority health since the 1960s. I couple this historical overview with an empirical assessment that introduces a novel and extensive dataset of every presidential discussion of minority health spanning five decades (1960-2016). This study finds that, since the early 1990s, presidents have transported their discussion of minority health beyond the confines of Washington, DC, traveling to speak to local communities throughout the nation that have a disproportionate number of blacks and Latinos. Moreover, a presidential discussion of minority health leads to greater salience on this issue and thus increases public health awareness. This work suggests that presidential messaging on minority health provides a framework for minority groups to understand and discuss the health disparities that may plague their communities.

  13. Multiculturalism and legal autonomy for cultural minorities

    Directory of Open Access Journals (Sweden)

    Morten Ebbe Juul Nielsen

    2013-11-01

    Full Text Available Does multiculturalism imply that certain cultural minorities – nomos groups, whose cultural conceptions extend in important ways into views about the law – should have forms of legal autonomy that go beyond normal multicultural accommodations such as exemptions and special protection? In other words: should we allow «minority jurisdictions» for multicultural reasons and give certain minorities powers of legislation and adjudication on certain issues? The paper sketches how one might arrive at such a conclusion given some standard multicultural reasoning, and then proceeds by examining eight key rejoinders to such a proposal. None of these rejoinders provide by themselves knockdown arguments against extending multicultural rights to forms of legal autonomy, but together they do provide a basis for some skepticism about the cogency and desirability of at least more ambitious forms of legal autonomy for cultural minorities within a liberal framework.http://dx.doi.org/10.5324/eip.v7i2.1798

  14. Liberal Critique of the Minority Rights’ Concept

    Directory of Open Access Journals (Sweden)

    Filip Majetić

    2010-04-01

    Full Text Available Controversies regarding the minority rights’ concept within liberal theory are opening up a debate in the political and academic communities of the Western democracies. Minority rights are discussed from the point of view of liberalism since it is more hospitable as a theory than conservatism and socialism, and due to the fact that it defines political morals in those countries. The aim of this article is to offer answers to some of the debate’s key questions. Should the liberals accept the model of universal individual rights combined with special minority rights within the liberal concept of social justice, founded on the principle of individual equality? Is a generalized, “non-discriminative” concept, such as the Western democracies’ key for fair treatment of ethno-cultural issues, really fair? Where are the limits of liberal tolerance set, and can liberalism be the cultures’ intersection point? By analyzing the opposed positions of various significant liberal theoreticians about the afore-mentioned and other issues, this article points to the questionable consistency of liberal critique of national and ethnic minority rights on the level of political legitimacy whilst this question remains open on the theoretical stage.

  15. Language choice in a minority school

    Science.gov (United States)

    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.

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.

The influence of the social networks like instrument of communication is not exempt from risks for the quantity of information that is facilitated and is shared. The lack of a specific regulation that he contemplates from the point of view of the Law which is the protection that a minor must have, does that there take place situations of abandonment of the rights of the same ones.The opportunity of regulation has been left to escape in the future law of protection of the infancy, nowadays in phase of preliminary design, since it does not refer to the social networks since it had been desirable. The current procedure as for minors, as well as those of protection of information, between others, do not turn out to be sufficient to contemplate all the situations of risk that can be given in the above mentioned area. In the present work we propose to think on minors and social networks raising some legal questions, and trying to contribute some response to the problematics that appears in the juridical area.

    The number of underage refugees arriving in Germany has rapidly increased since 2015. Many of these children and adolescents have been and still are, exposed to a large number of stressful circumstances. The group of those helping refugee minors is heterogeneous with both volunteers and professional workers from the fields of child welfare and healthcare services. Easily applicable instruments to assess both burdens and resources are needed in order to plan appropriate interventions. This paper focuses on instruments for assessing the circumstances of refugee minors and includes pilot data of an online-based screening instrument to assess burdens and resources (providing online resource and trauma assessment for refugees, PORTA). Field application was tested by the staff of a clearing and preclearing institution with 33 cases and good practical feasibility was reported. Applying a simple to use screening instrument for refugee minors and their helpers, which is available in several languages creates the possibility of a shared definition of problems and solutions and is beneficial to helpers (e.g. volunteers, youth welfare services and medical doctors) as well as refugee minors.

    2016-09-01

    Full Text Available The article tries to explore the practical application of the soft law, in concrete terms, the documents adopted by the Organization for Security and Co-operation in Europe, referring to the models of participation of national minorities in public life in the case of Bosnia and Herzegovina. The objective of the research was to assess the legal and political grounds for functioning national minority councils as participation and consultative mechanisms, scope of responsibilities and capacities in relation to their effectiveness and impact and to identify relevant good practices on such mechanisms. The political and decision-making structures in Bosnia and Herzegovina demonstrated lack of actual commitment to the realization of the rights of minorities referring to participation in decision-making processes. Bearing in mind formal position within parliaments, visibility, and a significant promotional capacity for presence in the public sphere, the councils on national minorities may represent a significant body and channel for the minority – majority dialogue. However, at the moment, the national minority councils’ capacity to ensure participation of national minorities in Bosnian political life and their influence in decision-making process remains insufficient. In general, the consultative mechanisms, within their mandated responsibilities, have had insignificant and minimal impact on the practical, political and legislative segment.

    Sextortion (threats to expose sexual images to coerce victims to provide additional pictures, sex, or other favors) has been identified as an emerging online threat to youth, but research is scarce. We describe sextortion incidents from a large sample of victims (n = 1,385) and examine whether incidents occurring to minors (n = 572) are more or less serious than those experienced by young adults (n = 813). We ran advertising campaigns on Facebook to recruit victims of sextortion, ages 18-25, for an online survey. We use cross tabulations and logistic regression to analyze incidents that began when 18- and 19-year-old respondents were minors (ages 17 and younger) and compare them with incidents that began at ages 18-25 years. Most minor victims were female (91%) and aged 16 or 17 when incidents started (75%). Almost 60% of respondents who were minors when sextortion occurred knew perpetrators in person, often as romantic partners. Most knowingly provided images to perpetrators (75%), but also felt pressured to do so (67%). About one-third were threatened with physical assaults and menaced for >6 months. Half did not disclose incidents, and few reported to police or websites. Perpetrators against minors (vs. adults) were more likely to pressure victims into producing initial sexual images, demand additional images, threaten victims for >6 months, and urge victims to harm themselves. Sextortion incidents were serious victimizations, and often co-occurred with teen dating violence. We describe resources so that practitioners can help victims find support and legal advice and remove posted images. Copyright © 2017 The Society for Adolescent Health and Medicine.

    While major mergers and their tidal debris are well studied, equal mass galaxy mergers are relatively rare compared to minor mergers (mass ratio tails in minor mergers can range over orders of magnitude on both local and global scales, and include several star forming regions with higher than normal SFE. From the tidal debris environments in our study, this variance appears to stem from the formation conditions of the debris. New results from the first survey of molecular hydrogen in minor merger tidal debris will be presented. Current surveys of the 2.12 micron line of molecular hydrogen, CO(1-0), and HI for 15 minor mergers, are providing a larger sample of environments to study the threshold for star formation that can inform star formation models, particularly at low densities.

    Sexual minorities are more likely than heterosexuals to engage in unhealthy eating behaviors. The purpose of this study is to examine sexual minority stressors and internalizing symptoms as predictors of unhealthy eating behaviors among sexual minority youths. We used longitudinal data from 1461 sexual minority youths 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. 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. 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.

    Sexual minority adolescents (lesbian, gay, bisexual) experience disparities in behavioral health outcomes compared to their heterosexual peers, generally attributed to minority stress. Although evidence of the applicability of the minority stress model among adolescents exists, it is based on a primarily adult literature. Developmental and generational differences demand further examination of minority stress to confirm its applicability. Forty-eight life history interviews with sexual minority adolescents in California (age 14-19; M = 19.27 SD = 1.38; 39.6% cismale, 35.4% cisfemale, 25% other gender) were completed, recorded, transcribed, and analyzed using thematic analysis in QSR NVivo. Following a consensus model, all transcripts were double coded. Results suggest that minority stress is appropriate for use with adolescents; however, further emphasis should be placed on social context, coping resources, and developmental processes regarding identity development. A conceptual model is provided, as are implications for research and practice. Copyright © 2016 The Foundation for Professionals in Services for Adolescents. Published by Elsevier Ltd.

    2016-01-01

    In prior research with primarily heterosexual religious and spiritual individuals, positive and negative forms of religious coping have been posited to moderate the links between minority stressors and psychological outcomes (Kim, Kendall, & Webb, 2015; Szymanski & Obiri, 2011). With a sample of 143 sexual minority people, the present study extended these hypotheses by examining the moderating roles of positive and negative religious coping in the link of 2 sexual minority-specific minority stress variables (heterosexist discrimination, internalized heterosexism) with psychological distress and well-being. In partial support of our hypotheses, we found that positive religious coping moderated the relation of internalized heterosexism and psychological well-being such that greater positive religious coping weakened the deleterious impact of internalized heterosexism on psychological well-being. Negative religious coping did not moderate any links. As the first test of the moderating roles of religious coping styles in the sexual minority stress-psychological distress link, the present study yields important findings for research and practice with religious and spiritual sexual minority individuals.

  14. Vaccines for minor use and minor species: technical difficulties to solve and consequences in legal definitions.

    Vannier, P

    2004-01-01

    To identify the difficulties of the problem and to try to find some solutions with their consequences in legal provisions, different aspects have to be considered: the possible definitions of minor species and minor indications and the limits of such definitions, the present applicable directives and possible modifications induced by extrapolation of technical results, by reduction of requirements. According to the complexity of the problem, a pragmatic approach with a certain flexibility, founded on a case-by-case assessment, seems to be necessary. The basis of the CVMP position paper regarding the availability of products for minor uses and minor species mainly focused on medicinal products and MRLs is interesting to consider in the case of vaccines, in the light of technical requirements of Title II of EU Directive 2001/82/EC. Even if definitions of minor species and minor uses are needed to give a legal basis for the problem, they have limits and some examples will be given. Reduction of requirements and extrapolation seem possible in a relatively easy way when data are available for major use and major species. A reduction of requirements is much more difficult to set up when such data are not available. Requirements for quality, safety and efficiency will be assessed including the indications of notifiable diseases. When all these aspects have been considered, it is essential to avoid a disharmonised approach from the National Regulatory Authorities. So, the possibilities of a specific legal framework on and a centralised procedure for marketing authorisations have to be discussed.

    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).

    This article explores the complexities surrounding the human rights of minority women. With analytical focus on Romani women in Europe it seeks to contribute with new insight into the grey areas of rights issues, where groups within special rights categories share different human rights concerns......, by being both women and members of a minority group. Through an investigation of how contemporary human rights law and politics serve to address the concerns of Romani women, it sheds light on the challenges that the Romani women’s issue presents to the international human rights framework...... rights attention that they claim. It is argued that in order to strengthen the validity of human rights in the lives of Romani women, as a framework that ensures their full and equal protection, special attention needs to be given to interrelated grounds and forms of discrimination. “Intersectionality...

    2009-04-01

    Full Text Available Abstract Previous studies about unaccompanied refugee minors (URMs showed that they are a highly vulnerable group who have greater psychiatric morbidity than the general population. This review focuses on mental health issues among URMs. Articles in databases PsycINFO, Medline and PubMed from 1998 to 2008 addressing this topic were reviewed. The literature had a considerable emphasis on the assessment of PTSD symptoms. Results revealed higher levels of PTSD symptoms in comparison to the norm populations and accompanied refugee minors. In several studies, age and female gender predicted or influenced PTSD symptoms. The existing literature only permits limited conclusions on this very hard to reach population. Future research should include the analysis of long-term outcomes, stress management and a more thorough analysis of the whole range of psychopathology. Additionally, the development of culturally sensitive norms and standardized measures for diverse ethnic groups is of great importance.

    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. (c) 2005 APA

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.

    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

    2010-12-01

    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.

  3. Research into minorities: between science and politics

    Full Text Available The article examines the interplay between science and politics in minority research in the period 1979 to mid-1980s at the University of Tromsø. Research was influenced by different conditions at the time, such as political events and policy priorities and ideological of streams in academia. Three factors influenced the choice of theme, priorities and approaches to minority research in North Norway. The first factor was the damming of the Alta-Kautokeino river, followed by Sami rights struggle and political changes towards the Sami population in Norway. What consequences did the political case for the research for the academic environment in the Northern Norway? The second factor was the research program run by the Norwegian general scientific Research (NAVF. An analysis on the relevant themes and focus areas within minority research is undertaken on basis of the research program. Finally I will use the methodological and research political discussions on emic and etic research positions that took place in the 1980s. Was it the Sami themselves, or also the researchers belonging to the majority that had the right to pursue research on the Sami? Sources consist of internal documents, reports, research papers and oral sources from the UiT.

    Thrombolysis is often withheld from acute ischemic stroke patients presenting with mild symptoms; however, up to 40% of these patients end up with a poor outcome when left untreated. Since there is lack of consensus on the definition of minor symptoms, we aimed at addressing this issue by looking for features that would better predict functional outcomes at 3 months. Among all acute ischemic stroke patients admitted to our Stroke Unit (n = 1,229), we selected a cohort of patients who arrived within 24 hours from symptoms onset, with baseline NIHSS ≤6, not treated with thrombolysis (n = 304). Epidemiological data, comorbidities, radiological features and clinical presentation (NIHSS items) were collected to identify predictors of outcome. Our cohort was tested against minor stroke definitions selected from the literature and a newly proposed one. Three months after stroke onset, 97 patients (31.9%) had mRS ≥ 2. Independent predictors of poor outcome were age (OR 0.97 [95% CI 0.95-9.99]) and baseline NIHSS score (OR 0.79 [95% CI 0.67-0.94]), while cardioembolic aetiology was negatively associated (OR 3.29 [95% CI 1.51-7.14]). Items of NIHSS associated with poor outcome were impairment of right motor arm (OR 0.49 [95% CI 0.27-0.91]) or the involvement of any of the motor items (OR 0.69 [95% CI 0.48-0.99]). The definition of minor stroke as NIHSS ≤3 and the new proposed definition had the highest sensitivity and accuracy and were independent predictors of outcome. Our study confirmed that in spite of a low NIHSS score, one third of patients had poor outcome. As already described, age and NIHSS score remained independent predictors of poor outcome even in mild stroke. Also, motor impairment appeared a major determinant of poor outcome. The new proposed definition of minor stroke featured the NIHSS score and the NIHSS items that better predicted functional outcome. Awareness that even minor stroke can yield to poor outcome should sensitize patients to arrive early

    Lesbian, gay, and bisexual (LGB) individuals report higher levels of depression and anxiety than heterosexual people. Genetic factors may be a 'common cause' of sexual minority status and psychological distress. Alternatively, these may be correlated because of non-genetic environmental factors (e.g. minority stressors). This study investigated minority stressors and distress in monozygotic twins discordant for sexual minority status. This design provides a test of the role of non-shared environmental factors while minimizing differences due to genetics. Thirty-eight twin pairs in which one was heterosexual and the other was LGB completed a survey. Differences between twin pairs in minority stressors, rumination, psychological distress, and gender non-conformity were examined. Associations between these variables were also tested. Although there were no significant group differences for distress, LGB twins had higher rumination, a vulnerability factor for distress, than heterosexual co-twins. LGB twins also had higher scores than heterosexual co-twins on expectations of rejection, active concealment, self-stigma, prejudice events, childhood gender non-conformity, and lower scores on sexual orientation disclosure. Differences between twin pairs in rumination were positively associated with differences in acceptance concerns and self-stigma. Finally, self-stigma was positively associated with rumination in the full sample of heterosexual co-twins and microaggressions were positively associated with rumination when looking at exclusively heterosexual co-twins. These results support environmental factors as a causal explanation for disparities in rumination between LGB and heterosexual individuals. These factors likely include minority stressors. Rumination may also be associated with minority stressors in heterosexual MZ co-twins of LGB individuals.

    Post-stroke depression (PSD) is one of the most frequent complications of stroke, with a prevalence ranging 20-60%. As PSD seems to be related to stroke severity, we hypothesized that the prevalence of PSD would be lower in patients with minor stroke. We investigated the prevalence and predictors of PSD over a 30-month follow-up period in a cohort of patients with minor ischaemic stroke (NIHSS≤5). We enrolled 105 patients (mean age 64.38±11.2years, M/F 69/36). PSD was diagnosed in 43 (41%) patients, 40 (93%) of whom had dysthymia; 22% of patients were already depressed at 1month. The most frequent depressive symptoms (DSs) were working inhibition, indecisiveness, and fatigability. Patients who developed PSD were less educated (P=0.044) and diabetic (P=0.006). After excluding patients that were already depressed at 1month, we performed a logistic regression model to detect predictors of PSD. Crying (P=0.012, OR 1.067, CI 0.269-4.553) and guilt (P=0.007, OR 0.037, CI 0.02ì03-0.401) at baseline were two DSs found to be significantly correlated with PSD. Higher educational level (P=0.022, OR 0.084, CI 0.010-0.698) and diabetes (P=0.007, OR 14.361, CI 2.040-101.108) were the risk factors significantly correlated with PSD. Post-stroke depression is frequent even in patients with minor stroke. Early detection of DSs might help to predict long-term development of PSD. No correlation was observed between lesion site or side and the development of PSD. © 2011 The Author(s). European Journal of Neurology © 2011 EFNS.

  2. Russian Minorities in the Former USSR

    2000-12-01

    Full Text Available The end of the Soviet Empire has brought out the importance of the nationalities problem and the contradictory results produced by the various formulas applied since 1922 for resolving it. Two characteristics conditioned the evolution of this problem in the Soviet Union: the choice of a territorial model which would give a important role to the Empire’s non-Russian peoples; and the contradiction between the theoretical base established by Lenin and Stalin for solving the problem and actual practice, which followed traditional channels. The result was a new territorial structure endowed with the external elements characteristic of a state but cancelled out by the superiority of a party and by a policy ofprotecting minorities deliberately designed to make the new national entities nonviable. The lack of an adequately institutionalized state was at the root, of the virtual disappearance, after the collapse of the Communist Party, of links between the center and the periphery, a situation that nationalism, where it existed, exploited to gain powerand that governing minorities, meaningless outside the framework created by the USSR, exploited to stay in power. The result was none other than the appearance of new ethnically heterogeneous states with imprecise borders, bereft of the systems of interethnic equilibriumthe Soviet administration had created, and willing to consolidate their independence and identity at the expense of minorities such as the Russians, which have been discriminated against at times and excluded from political and cultural life at others. This phenomenonhas reduced the chances for the new states’ integration on an international level, placed a burden on the incipient democratic systems and made for tense relations with Russia.

    2014-04-01

    The primary purpose of this article is to review the career outcomes of a research training program specifically targeted to young psychiatric researchers from minority populations underrepresented in psychiatry. The aims of the program were (1) to support psychiatric investigators from under-represented populations in the development and maintenance of research careers and (2) to identify the factors which influence successful research career development. Demographic data from 99 program participants were collected from an online survey as part of a systematic program evaluation, and through a follow-up internet search. Outcome measures included current academic position, number and types of post-training grants received, number of peer-reviewed publications, and comparison of post-training career outcomes with those from other highly regarded research training programs. Of the 99 psychiatrists accepted into the program, 55 responded to the online survey; additional information on non-responders was obtained through a follow-up internet search. Results indicated that 64% of program trainees identified their primary employment setting as academic/research; 70% reported publication of their research findings, and 64% reported the award of post-training research grants. The percentage of program graduates appointed to academic faculty positions and their receipt of R01 and/or K awards, exceeded that of two highly regarded national training programs. The study further identified major factors influencing successful research career development. Findings from this study strongly suggest that research training programs targeted to young minority psychiatrists can be successful in supporting the development and maintenance of their research careers. The decline in the availability of such programs does not portend well for increasing the numbers of underrepresented minority psychiatric researchers.

    A group of patients suffering major debility after minor whiplash head trauma, seen in one office practice, has been retrospectively studied. Typically, acute neck and upper back aches and headache evolved into a multiple somatic, affective and cognitive dysfunction syndrome. Neuropsychological evaluations noted impairments on tests of cognitive flexibility, non-verbal reasoning, new learning/memory, psychomotor agility, and attention. However, in the subacute period, neurological examination, imaging and clinical electrophysiological studies were unable to localize, structurally or functionally, the source of the above dysfunctions.

    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.

  13. ISLAM AND MINORITIES: Managing Identity in Malaysia

    Directory of Open Access Journals (Sweden)

    Ahmad Suaedy

    2010-02-01

    Full Text Available The Malaysian general election in March 2008 raised an interesting and new phenomenon. For the first time since independence in 1957, the ruling alliance known as the National Front (Barisan Nasional, BN failed to secure two thirds of seats in parliament and lost control of five of Malaysia’s 13 states. This was due to the challenge presented by the new opposition alliance known as the Alternative Front (Barisan Alternatif, BA or the People’s Alliance (Pakatan Rakyat, PK which won more than 36% of seats in parliament and gained control of the five states. In the 2004 election, BN secured the largest ever percentage of seats in parliament with 91%. What is interesting is that it seems that this significant increase in support for the opposition is  due to their offer to change the way minorities and ethnicity is managed. They  propose a move from “Bumiputera Supremacy”, or affirmative action for the approximately 65% of “Bumiputera” Malaysians (the rest being largely of Chinese or Indian ethnicity, to “The People’s Supremacy”, which involves eradicating affirmative action based on ethnicity, basing it instead on need, for  instance need due to poverty. This would potentially increase the likelihood  of justice and equality for all ethnic or racial groups. This paper connects the phenomenon of change, as seen in the about turn in the results between the  2004 and 2008 elections, to the more global trend in which minorities are standing up to demand their rights in this era of globalization, and to the challenge multiculturalism presents to parts of the Muslim world such as Malaysia. Malaysia, a Muslim majority nation that has formally declared Islam the official state religion with Yang di-Pertuan Agong (the King as  Head of the State and symbol of Islam, is one example, though not necessarily  representative, of how Islam and Muslims manage minorities and identity or  multiculturalism within the process of globalization

    Flitney, Adrian P.

    2005-05-01

    A quantum version of the Minority game for an arbitrary number of agents is studied. When the number of agents is odd, quantizing the game produces no advantage to the players, however, for an even number of agents new Nash equilibria appear that have no classical analogue. The new Nash equilibria provide far preferable expected payoffs to the players compared to the equivalent classical game. The effect on the Nash equilibrium payoff of reducing the degree of entanglement, or of introducing decoherence into the model, is indicated.

    Pleomorphic adenoma is the most common benign tumour of salivary glands which is Known for its wide pleomorphic architecture. It accounts for 45-75% of all salivary gland neoplasm. It can involve major as well as minor salivary glands. Among minor salivary glands (5-10% of cases) the palate lip, nasal cavity, pharynx, larynx and trachea are the most common sites. Diagnosis is made with biopsy along with histopathology. Wide excision with biopsy and removal of underlying extension of tumour is the treatment of choice. Sixty years old farmer presented with painless swelling in the upper lip for the last 8 years. History revealed recurrent mass in the midline of upper lip with no other complaints. He was operated 3 times for this complaint in the past. Belonging to poor socioeconomic status no biopsy records were found. On examination 3×4 cm hard and mobile mass was found. Lymph nodes of head and neck and parotid gland revealed no enlargement. Surgery by wide excision was planned. After baseline investigation surgery was done and the mass sent for histopathology. Biopsy reports showed pleomorphic adenoma on unusual site. Dissection of salivary gland tumour is important as they have propensity to metastasize. Wide local excision along with biopsy is the method of choice. Proper surgical techniques are required to avoid recurrence.

    2013-07-01

    Over the past decades, clinical research has increasingly been subjected to ethical requirements and legal regulation. The specific focus of ethical and legal frameworks on competent adults (which serve as the paradigmatic research subject), however, has created an ambivalent attitude towards pediatric clinical research. On one hand, minors are regarded as a vulnerable population that deserves additional protection against the risks and burdens involved in clinical research. On the other hand, the population of minors should not be denied (or not get timely) access to the benefits of clinical research. In this paper, we will explore the legal regulation and ethical guidance that currently governs pediatric clinical research in the European Union and discuss the future challenges in this field. In addition, we will discuss major ethical concerns in pediatric clinical research, with a focus on the acceptability of research risks and the informed consent process. In the discussion, we will address key concerns in both regulating pediatric clinical research and implementing ethical and legal requirement in the actual pediatric research conduct.

  2. Urey Prize Lecture: Binary Minor Planets

    The discovery of binary systems in the near-Earth, main belt, and Kuiper belt populations provides an abundance of new data that expand our knowledge of the physics and chemistry of the solar system. Binary minor planets form as a result of collisional, tidal, and capture processes that are important to study as they play major roles in the formation and evolution of planetary systems. The frequency of occurrence of such processes directly reflects the dynamical environment in the various populations. Observations of binaries provide a powerful way to measure the bulk properties of small bodies, which in turn lead to inferences about their composition and internal structure. These data may offer a rare glimpse of what physical and chemical conditions prevailed when protoplanets formed, and what subsequent evolution took place. In the case of the Kuiper Belt, the study of a handful of binaries forces us to rethink how dense and how bright these bodies are, and to significantly revise our current mass estimates for the entire population. The number of known binary minor planets has increased dramatically over the past few years, with roughly ten new discoveries each year. I will attempt to summarize recent developments, with examples drawn from my observations with the Hubble, Palomar, Keck, Arecibo and Goldstone telescopes.

  3. Major emerging problems with minor meloidogyne species.

    2013-11-01

    Root-knot nematodes (Meloidogyne spp.) represent one of the most polyphagous genera of plant-parasitic nematodes. To date, close to 100 valid species are recognized. In contrast to the size of the genus, the majority of past research focused on a small number of species, i.e., the so-called 'major' species M. arenaria, M. hapla, M. incognita, and M. javanica. This review highlights recent work aimed at 'minor' root-knot nematodes: M. chitwoodi, M. fallax, M. minor, M. enterolobii (=M. mayaguensis), M. exigua, and M. paranaensis. Some of these species have been described only recently. After a brief profile of each species, identification methods and their application in Meloidogyne spp. are summarized. Intraspecific variation and its impact on plant resistance breeding are discussed and interactions between M. enterolobii and Fusarium solani are highlighted as an example of synergistic interactions with other plant pathogens. Future research on Meloidogyne spp. is not only shaped by recent breakthroughs such as completing the genome sequences of M. hapla and M. incognita, but is also influenced by changes in agriculture. Taken together, the aim of this review is to draw attention to previously neglected and newly described Meloidogyne spp. that are developing into major problems for agriculture in tropical and temperate climates.

  4. Minor and major health: a Nietzschean reading.

    Biato, Emília Carvalho Leitão; Costa, Luciano Bedin da; Monteiro, Silas Borges

    2017-03-01

    This paper aims to discuss the concept of health, understood as multiple and plural. We use Friedrich Nietzsche's philosophical thought as an analytical tool, allowing us to reach a typology involving minor and major health. While the first is normative and sustained by an ideal of healing, the second is an expanding strength, a condition constantly achieved. If minor health follows a preset life moralization script, major health relates to the expanded living being, which affirms its creative nature and transcends established rules. The notion of major health embraces the overcoming of imperative models rooted in biomedicine-based practices and approaches to health collective actions. Nevertheless, on the one hand, if this movement extends the co-participatory nature between staff and users of the health system, on the other hand, it lacks more radical actions to break with the moral nature of health-disease processes. Not refusing life's own vicissitudes, major health understands the need to incorporate pain and suffering involved in individuation movements.

    Teres minor atrophy occurs either in isolation, associated with other rotator cuff muscle pathologies or in quadrilateral space syndrome. In the latter condition, compression of the axillary nerve is the likely cause; however, the anatomy of the nerve to teres minor and how this may relate to isolated teres minor atrophy have not been extensively investigated. In light of the significance of teres minor atrophy in shoulder pathology, we performed a combined radiological and anatomical study of teres minor and its nerve supply. Cadaveric dissection of nine shoulder specimens from eight cadavers was performed to investigate the anatomical variability in course, length and branching pattern of both the teres minor nerve and the axillary nerve. Radiological imaging and reports were analysed on all shoulder magnetic resonance images performed over a 1-week period at four radiology clinic locations in an attempt to identify the incidence of isolated teres minor atrophy and review teres minor atrophy in association with other shoulder pathology. Finally, we studied a case of isolated teres minor atrophy identified during a routine undergraduate dissection class. Considerable anatomical variation was noticed in cadaver dissections in the nerve(s) supplying teres minor muscle revealing several various points where it may be vulnerable to impingement or injury at along its course. Analysis of 61 shoulder MR images revealed two patients with shoulder complaints that had isolated teres minor atrophy. Case-based study of these two male patients revealed other associated shoulder injury but the presentation was markedly different and clinically distinct from quadrilateral space syndrome. Isolated teres minor atrophy is a relatively common shoulder pathology which appears to be clinically distinct from other syndromes with rotator cuff muscle atrophy including quadrilateral space syndrome. The exact aetiology is unknown but cadaveric dissection in this study suggests the

    Disparities in substance use have been observed in sexual minority youth, but less is known about willingness to use substances, an important precursor to actual use. The goal of this study was to examine willingness to use cigarettes, alcohol, and marijuana among sexual minority youth compared to their non-sexual minority counterparts using both cross-sectional and longitudinal data. The present study drew on two waves (Times 1 and 2; 6 months apart) of data collected during high school as part of a prospective study of substance use initiation and progression in Rhode Island. At Time 1, participants (N = 443) ranged in age from 15 to 20 years (M age = 16.7 years, 26.6% sexual minority, 59.5% female, 72.0% White). Participants self-reported their sexual identity and attraction, lifetime use of alcohol, cigarettes and marijuana, and cigarette, alcohol, and marijuana use willingness (i.e., if offered by a best friend or group of friends). In cross-sectional multivariate regression models, sexual minority youth were more likely to report willingness to use cigarettes (p sexual minority counterparts. Longitudinal multivariate regression models revealed that sexual minorities were only significantly more likely to report cigarette willingness at Time 2 compared to their non-sexual minority counterparts (p sexual minority status. Sexual minority youth reported more willingness than non-sexual minority youth to use substances offered by peers; however, longitudinal analyses revealed that peers appear to play a role only in willingness to smoke cigarettes for these youth, and thus peer influence may be a contributing factor in explaining tobacco-related disparities among sexual minority youth. Given that stigma and peer groups may a particular risk factor for tobacco among sexual minority youth, our findings highlight the importance of prevention programs such as social marketing approaches that correct social norms, reduce stigma, and provide refusal-skills training to

    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.

    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

    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. PMID:26424904

    2017-03-01

    Full Text Available The article examines minor clerics (clerici in Carolingian texts. Comparing episcopal capitularies from Italy and Francia suggests that clerici played a more prominent role in Italian church life. An analysis of charters from the monastery of Monte Amiata reveals a high proportion of clerici. They appear as a rurally-based group, with varying levels of education, but of some local social standing, and were often mature men with children. The prevalence of such clerici may be related to the northern Italian structure of pievi, and the opportunities these provided for mixed patterns of father-son and uncle-nephew inheritance of church office. The blurring of the lay/clerical divide by such clerici may have particularly worried eleventh-century church reformers coming to Italy from other regions of Western Europe.

    Full Text Available In my paper, I present a qualitative approach to the linguistic landscape of Hungarian schools in Sepsiszentgyörgy/Sfântu Gheorghe, Romania. These landscapes are called schoolscapes as they represent the material environment where texts and images “constitute, reproduce and transform language ideologies” (Brown 2012: 282. These manifestations reveal a lot about language learning and teaching in a formal educational environment. Beyond the simple representations of languages in education, we may trace more or less hidden curriculum details of foreign- and second-language teaching (English/German, Romanian in a Hungarian-Romanian dominant bilingual setting. My aim is to describe the visual manifestations of the differences and similarities between the languages taught to minority children and the mutual efforts of teachers and students to meet the basic challenges of learning and teaching these languages.

    Resource allocation takes place in various types of real-world complex systems such as urban traf- fic, social services institutions, economical and ecosystems. Mathematically, the dynamical process of complex resource allocation can be modeled as minority games in which the number of resources is limited and agents tend to choose the less used resource based on available information. 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 strategies to suppress and elim- inate 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 mi...

  19. Autochthonous Linguistic Minorities in the Italian Alps:

    Directory of Open Access Journals (Sweden)

    Ernst Steinicke

    2011-08-01

    Full Text Available More than any other area in Western Europe, the Alps, especially the Italian Alps, are home to great ethno-cultural diversity: there, no less than seven autochthonous linguistic minorities coexist side by side with the respective official majority. Now being considered an important cultural heritage by the state as well as by the regions, new legislation offers protection to all ‘linguistic-historic minorities’ in Italy. Our study shows, however, that it is quite difficult to maintain such groups, since it is largely unknown where exactly the minority areas are situated. Based on that, local actor groups in various communities take advantage of this lack of knowledge and declare themselves minority territories although they show no linguistic varieties. An important objective of this project is therefore to present a cartographic representation of this linguistic diversity. Subsequently, the contribution discusses case studies of distinct ethno-linguistic self-awareness. Even though with Law No. 482 a first important step was taken to preserve the linguistic minorities, their progressive decline by territorial and numerical criteria cannot be denied. Today, besides unfavorable bio-demographic factors and “diffuse ethnicity,” other causes are current demographic processes. In this framework the amenity migrants, those new immigrants who have discovered the mountains as a new, desirable settlement space, play a decisive role by reinforcing the assimilation process.Les Alpes, plus précisément les Alpes italiennes, plus que toute autre région d'Europe Occidentale, sont un lieu de grande diversité ethnoculturelle : pas moins de sept minorités linguistiques autochtones y coexistent, côte à côte avec la majorité officielle correspondante.

    1999-05-01

    Full Text Available Tacitus’ portrayal of Agrippina MinorAncient historiography has more in common with the historical novel than with modem historiography. The Annals of Tacitus should be seen as an artistic, narrative text which demands active participation by the reader in the process of interpretation. A narratological analysis of Tacitus' description of the life and death of Agrippina, mother of the emperor Nero, reveals a serious ethical reflection on the atrocities committed by the imperial family. Agrippina is characterised as an exceptionally strongwilled woman who had an immense influence on the Roman Empire while she was the wife of the emperor Claudius and mother of his successor, Nero. On the other hand, her typically female character traits are accentuated from which the reader has to infer that it was precisely the fact that she was a woman which made her authoritative position intolerable.

    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.

    Full Text Available In this article the introductory part deals with Christian guidelines regarding the rights of minority groups. In the ensuing part the provision of education according to the unique educational needs of minority groups is discussed within the context of the presented guidelines. It is indicated that own education is internationally accepted as one of the major rights of minority groups. Within the international context, for example in the treaties of Unesco and in the educational provision of several countries, it is accepted that minority groups also prefer their own education institutions in order to effectively provide in their unique educational needs. In this article the more general requirements, regarding the characteristics of the education institution needed to meet the unique educational needs of a particular minority group are also identified. The impending problems in South Africa regarding own education schools for minorities are discussed briefly. In order to find possible solutions the situation in the Netherlands regarding "bijzondere scholen” to provide in the unique educational needs of particular interest groups and particularly religious groups is analysed. The conclusion arrived at is that the mentioned situation does not oppose Christian guidelines if minorities need each other to influence educational change, that the acknowledgement of the educational rights of minority groups promotes national unity, that the educational rights of minorities should imply freedom of establishment, denomination and institution and that the educational rights of minorities are fully realised if their education is financially supported by government on an equal basis to that of the majority.

    Assess the mental health and substance use of sexual minority collegiate student-athletes in the United States, as compared with heterosexual college students and heterosexual student-athletes. Undergraduate students (N = 196,872) who completed the American College Health Association's National College Health Assessment (Fall 2008-Fall 2012 administrations). Written cross-sectional survey. Sexual minority student-athletes had a higher risk of experiencing mental health difficulties than their heterosexual athlete peers. There were no significant differences in mental health between sexual minority male athletes and nonathletes. Sexual minority female athletes appeared to fare better than nonathlete peers. Substance use was greater among sexual minority students (athlete and nonathlete) and was mediated by mental health. Participation in athletics does not appear to be associated with an elevated risk of negative mental health outcomes for sexual minority participants; however, there are disparities in mental health outcomes by sexual orientation regardless of athletics participation.

  6. NATIONAL MINORITIES IN THE LAW OF THE EC/EU

    2008-09-01

    Full Text Available In the law of the EC/EU the protection of national minorities is still a marginal matter. The EU has relied on general international law and on a European regional system of international law and, in case of necessity, accepted their norms. But in the 1990s there began a process of “de-economisation of the European integration” and the importance of national minorities became higher. Protection of the national minorities has not become a generally accepted legally binding principle of the EU, although in several legal acts issues of national minorities are mentioned. On the other hand, the political relevance of national minorities´ protection is very high. The importance of protection of national minorities in future will probably grow. It is a result of the adoption of the Charter of Fundamental Rights of the EU (2000 and of the discussions regarding the European constitution and the Treaty of Lisbon.

    The University of West Florida received a grant from the US Department of Energy to initiate a program on mentoring for Minorities in Mathematics and Science. The purpose of the program was to develop interest of minority freshman and sophomore students in teaching mathematics and science and then have these students act as role models for grade school students, especially for minorities who are experiencing difficulties in science and mathematics education. Fifteen students, one more than what was budgeted, participated in the project.

  8. Acinic Cell Carcinoma in Minor Salivary Glands of Retromolar

    OpenAIRE

    KOYUNCU, Mehmet; Atmaca, Sinan; Bedri KANDEMİR; ÇAKIL, Bünyamin

    2009-01-01

    Acinic cell carcinoma (ACC) is a rare malignant tumor of the salivary glands. ACC of the minor salivary glands is very rare. In the oral cavity, minor salivary gland tumors are rarely seen in the inferior anatomic regions like the retromolar trigone and the floor of mouth compared to the superior regions like the palate. We present a retromolar trigone ACC, a rare location in the oral cavity and discuss the relevant reports in the literature. Key words: Acinic cell carcinoma, minor salivar...

    The prevalence of minor physical anomalies was examined in a sample of 109 children with idiopathic mental retardation (65 boys and 44 girls). Control group consisted of 246 healthy schoolchildren (123 boys and 123 girls) aged 8 to 12 years. A comparison was made between number of found minor anomalies per child (W1) and their Waldrop weight scores (W2) in healthy and mentally retarded (MR) children. The MR children were found to have a higher number of minor anomalies per chil...

  10. Minority within a minority: being Bonpo in the Tibetan community in exile

    2012-01-01

    This thesis presents a study of the Bonpo in Dolanji, a Tibetan refugee settlement in North India. The Bonpo are a distinctive religious minority within the Tibetan refugee population. In the 1950s, Chinese Communist forces occupied Tibet and, in 1959, the fourteenth Dalai Lama fled Tibet into exile in India. In 1960, the Tibetan Government-in-Exile was established in Dharamsala, and emphasised a ‘shared’ Buddhist heritage as being central to the Tibetan national identity. This...

    While major mergers and their tidal debris are well studied, equal mass galaxy mergers are relatively rare compared to minor mergers (mass ratio pivotal role in the formation of most large galaxies. Tidal debris regions have large amounts of neutral gas but a lower gas density and may have higher turbulence. We use star formation tracers such as young star cluster populations and H-alpha and CII emission to determine the different factors that may influence star formation in tidal debris. These tracers were compared to the reservoirs of molecular and neutral gas available for star formation to estimate the star formation efficiency (SFE). The SFR in tidal debris can reach up to 50% of the total star formation in the system. The SFE of tidal tails in minor mergers can range over orders of magnitude on both local and global scales, and include several star forming regions with higher than normal SFE. From the tidal debris environments in our study, this variance appears to stem from the formation conditions of the debris. Current surveys of the 2.12 micron line of molecular hydrogen, CO(1-0), and HI for 15 minor mergers, are providing a larger sample of environments to study the threshold for star formation that can inform star formation models, particularly at low densities.

    2008-05-07

    Using functional magnetic resonance imaging, we contrasted major and minor mode melodies controlled for liking to study the neural basis of musical mode perception. To examine the influence of the larger dissonance in minor melodies on neural activation differences, we further introduced a strongly dissonant stimulus, in the form of a chromatic scale. Minor mode melodies were evaluated as sadder than major melodies, and in comparison they caused increased activity in limbic structures, namely left parahippocampal gyrus, bilateral ventral anterior cingulate, and in left medial prefrontal cortex. Dissonance explained some, but not all, of the heightened activity in the limbic structures when listening to minor mode music.

  14. MINOR INNOVATIVE ENTERPRISES AND METHODS OF THEIR FINANCING IN RUSSIA

    Directory of Open Access Journals (Sweden)

    A. G. Komissarov

    2011-01-01

    Full Text Available Minor enterprises do not have resources sufficient for investment. Present experience of venture financing and attraction of funds from finance markets is poor in Russia. Main minor entrepreneurship financing sources are state allocations in the form of subsidies, subventionsand donations. This support promotes economics diversification and increases jobs. The state becomes client of innovations and provides for business environment favorable for minor entrepreneurship and for subsequent diffusion of innovations. One of most efficient innovationactivity stimulation methods (applied to minor enterprises as well is provision for tax privileges, favorable state bank credits and preferences to innovation activity supporting commercial banks.

I conclude with a discussion of barriers to treatment for sexual minority women and recommendations for substance abuse treatment providers. PMID:22470226

  16. Minor Planet Center Data Processing Challenges

    Rudenko, Michael

    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

    VERA, the Vienna Environmental Research Accelerator, is especially equipped for the measurement of actinides, and performs a growing number of measurements on environmental samples. While AMS is not the optimum method for each particular plutonium isotope, the possibility to measure 239Pu, 240Pu, 241Pu, 242Pu and 244Pu on the same AMS sputter target is a great simplification. We have obtained a first result on the global fallout value of 244Pu/239Pu = (5.7 ± 1.0) × 10−5 based on soil samples from Salzburg prefecture, Austria. Furthermore, we suggest using the 242Pu/240Pu ratio as an estimate of the initial 241Pu/239Pu 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. PMID:23565016

  18. Unaccompanied Immigrant Minors: Where to Begin.

    Ciaccia, Kimberly A; John, Rita Marie

    2016-01-01

    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.

  19. Proposing a Health Humanities Minor: Some Lessons.

    Science.gov (United States)

    Engholm, Virginia Bucurel; Boria, Damon

    2017-12-01

    For those interested in developing baccalaureate programs in health humanities, this essay draws on our experience of developing a minor in health humanities to share insights on what to expect, strategies that work well, and how to deal with obstacles. These insights range from how to explain the concept of health humanities to stakeholders (faculty, administrators, and community partners) to how to decide where to house a health humanities program. We share our insights in a way that promises to translate well to different institutional contexts. That said, this paper is more relevant for institutional contexts where budgets are stressed and, consequently, proposals to invest in humanities programs are a difficult sell. This paper is divided into sections addressing how to (a) earn institutional support, (b) gain campus buy-in, (c) identify benefits of the proposed program, (d) decide where to house the program, (e) calculate program cost, and (f) secure external funding. We conclude with some final reflections on the current status of our program and why we are committed to health humanities education.

    Cusimano, Michael D

    2009-05-01

    In Canada and the USA, ice hockey is a cause of traumatic brain injury. Post-concussive symptoms are the most important feature of the diagnosis of concussion in sports and it is recommended that athletes not return to play while still symptomatic. Lack of knowledge of concussions could therefore be one of the main detriments to concussion prevention in hockey. The purpose of this research is to describe what minor league hockey players, coaches, parents and trainers know about concussion and its management. A questionnaire to assess concussion knowledge and return to play guidelines was developed and administered to players at different competitive levels (n = 267), coaches, trainers and parents (total adults n = 142) from the Greater Toronto Area. Although a majority of adults and players could identify mechanisms responsible for concussion, about one-quarter of adults and about a quarter to a half of children could not recall any symptoms or recalled only one symptom of a concussion. A significant number of players and some adults did not know what a concussion was or how it occurred. Almost half of the players and a fifth of the adults incorrectly stated that concussion was treated with medication or physical therapy. Nearly one quarter of all players did not know if an athlete experiencing symptoms of concussion should continue playing. This study demonstrated that a significant number of people held misconceptions about concussion in hockey which could lead to serious health consequences and creates a need for better preventive and educational strategies.

    Sexual minority women (e.g., lesbians, bisexual women, and women who prefer a female partner) are a known risk population for overweight, obesity, and mental health problems. Our objective is to compare sexual minority women with breast cancer to a control sample of sexual minority women without cancer to identify differences in healthful lifestyle practices, weight, well-being and mental health. This is a cross-sectional study of 85 sexual minority women with a breast cancer history (cases) matched by age and partner status to 85 sexual minority controls without cancer. We compared self-reported physical activity, fruit and vegetable intake, weight, quality of life, anxiety, and depression. Cases and controls had similar health behaviors, BMI, quality of life, anxiety, and depression. Of the weight-related behaviors, meeting the recommended guidelines of physical activity was significantly associated with lower likelihood of being overweight or obese, less depression, and better mental quality of life. Sexual minority women with breast cancer are similar to sexual minority women without cancer with respect to healthful behaviors, body weight, anxiety, depression, and quality of life. Lifestyle interventions to reduce the risk of poor outcomes after cancer should be implemented in this population as well as in sexual minority women without cancer.

    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.

    2016-01-01

    The empirical research examining substance use among sexual minority collegiate athletes is sparse. Problematically, this group may be at a greater risk of substance use due to their marginalized status within the context of sport. We examined different types of substance use during the past 30 days, and diagnosis of substance use disorders during the past 12 months, among sexual minority collegiate athletes. This study uses data from college students for the fall semester between 2008 and 2012 from the American College Health Association-National College Health Assessment. Sexual minority collegiate athletes had greater odds of past 30-day cigarette use, past 30-day alcohol use, past 30-day marijuana use, and indicating being diagnosed or treated for a substance use disorder during the past 12 months when compared to either heterosexual collegiate athletes or heterosexual nonathletes, but had similar odds on these outcomes when compared to sexual minority nonathletes. Sexual minority collegiate athletes also had greater odds of binge drinking during the past 2 weeks when compared to either heterosexual nonathletes or sexual minority nonathletes, but had similar odds on this outcome when compared to heterosexual collegiate athletes. Additional analyses by gender reveal that male sexual minority athletes are at the greatest risk of being diagnosed or treated for a substance use disorder. Possible explanations as to why sexual minority collegiate athletes (particularly males) may be at a greater risk of substance use disorders could include the difficulty of trying to maintain an athletic identity within a social environment that is traditionally homophobic.

  7. Archaeology of Extrasolar Rocky Minor Planets

    Science.gov (United States)

    Farihi, Jay

    2011-09-01

    Recent and ongoing work has demonstrated that empirical constraints on the frequency and chemistry of rocky planet formation around other stars, and signatures of water therein, can be found via the asteroidal debris orbiting and polluting white dwarf stars. These stellar remnants yield observable information that can be acquired no other way: the frequency, bulk chemical composition, and minimum mass of rocky minor planets around other stars. Asteroids are ancient planetesimals, the building blocks of the terrestrial planets. In the Solar System, we indirectly measure the composition of asteroids by studying meteorites. Analogously, we can obtain a picture of terrestrial planet formation at A- and F-type stars by studying the composition of extant asteroids as they fall onto and chemically pollute their white dwarf remnants. Critically, it is possible to identify significant amounts of water in these asteroidal systems, providing an indication of (current or prior) habitable environments as well as extrasolar testing grounds for models of water delivery to the Earth. I will present the latest and new developments in this area of research. I hope to include some results of an ongoing HST COS effort to study asteroidal debris as a function of post-main sequence age and main-sequence progenitor mass. Other highlights are two stars polluted by the debris of rocky planetary bodies sufficiently large to have been differentiated, and thus at least as large as Vesta or Ceres, the two largest asteroids in the Solar System. Currently, there is at least one compelling case for the accretion of water-rich, asteroidal debris, while the totality of known polluted white dwarfs hints at a significant population of water-rich asteroid analogs orbiting other stars.

    Full Text Available Contemporary society is faced with the question how to ensure suffiecient nutrition (quantity and quality for rapidly growing population. One solution can be consumption of edible insect, which can have very good nutritional value (dietary energy, protein, fatty acids, fibers, dietary minerals and vitamins composition. Some edible insects species, which contains a relatively large amount of fat, can have a potential to be a „good" (interesting, new source of minor lipophilic compounds such as sterols (cholesterol and phytosterols and tocopherols in our diet. For this reason, the objective of this work was to characterize the sterols and tocopherols composition of fat from larvae of edible insect Zophobas morio L. and Tenebrio mollitor L. Cholesterol and three phytosterols (campesterol, stigmasterol and β-sitosterol were reliably identified and quantified after hot saponification and derivatization by GC-MS. Other steroid compounds, including 5,6-trans-cholecalciferol were identified only according to the NIST library. Cholesterol was the predominant sterol in all analysed samples. Both types of larvae also contained high amount of phytosterols. Different region of origin had a no significant impact on sterols composition, while the effect of beetle genus was crucial. Tocopherols were analysed by reverse phase HPLC coupled with amperometric detection. Tocopherols content in mealworm larvae was lower than content in edible oils, but important from the nutritional point of view. Change of tocopherols composition was not observed during the storage under different conditions. Larvae of edible insect can be a potential good dietary source of cholesterol, but also vitamin D3 isomers, phytosterols and tocopherols.  

  9. Variation in Subjective Aging by Sexual Minority Status.

    Barrett, Anne; Barbee, Harry

    2017-06-01

    The past few decades have seen increased scholarly attention to gay and lesbian individuals' aging experiences; however, few studies examine differences in subjective aging by sexual minority status. We identify four perspectives on the association between sexual minority status and subjective aging-double jeopardy, crisis competence, gender interactive, and limited salience perspectives. We examine each perspective's predictions using data from the first wave of Midlife in the United States (1995-1996; MIDUS). Ordinary least square regression models reveal strongest support for the limited salience perspective, suggesting that sexual minority status has weaker effects on subjective aging than do other social factors, such as age, health, and gender. However, some results provide support for the gender interactive perspective, positing that the effect of sexual minority status on subjective aging varies by gender. Our study provides an organizational framework of theoretical perspectives that can guide further examinations of variation in aging experiences by sexual minority status.

    2004-12-01

    The LSU GAEMP (Geoscience Alliance to Enhance Minority Participation) program seeks to increase the number of under-represented minorities in the geosciences by targeting students at minority-serving institutions (MSIs) who have an undergraduate STEM (science, technology, engineering, or math) major that is not geology. The program, sponsored by a 5-year NSF award through the OEDG program, is administered by Geology and Geophysics faculty at LSU in collaboration with key science faculty at nine regional minority serving institutions (MSIs; seven Historically Black Colleges and Universities (HBCU) and two Hispanic Serving Institutions). These MSIs, especially several physics programs, provide well-trained, highly motivated graduates who compile excellent records in highly ranked graduate programs. These students also have strong potential because they have knowledge and skills relevant to graduate work in interdisciplinary areas. Forging collaborations with MSIs is crucial to exposing these talented students to geoscience education and career opportunities because most of these institutions do not have geoscience degree programs. The point of entry into GAEMP is a summer course that focuses on research to introduce basic geoscience concepts. Targeted recruits into GAEMP are MSI juniors that show high academic achievement and have non-geoscience STEM majors. Summer course participants are encouraged to, and supported in, cooperative research projects that are completed during the following academic year at the home institution. On receiving their baccalaureate degree, GAEMP participants are encouraged to apply to graduate school, especially at LSU where GAEMP graduate fellowships are available at both the M.S. and Ph.D. level. We use a variety of recruiting efforts to attract students into GAEMP including print media, a webpage, visits by LSU faculty and students to MSIs, and workshops at LSU for MSI faculty and students. With all these efforts, the enthusiastic

  13. Persistence among Minority STEM Majors: A Phenomenological Study

    Science.gov (United States)

    Williams-Watson, Stacey

    The United States needs to increase the number of science, technology, engineering, and math (STEM) graduates to remain competitive in the global market and maintain national security. Minority students, specifically African-American and Hispanic, are underrepresented in STEM fields. As the minority population continues to grow it is essential that higher education institutions improve minority students' persistence in STEM education. This study examined the problem of minority students' lack of persistence in STEM programs. The purpose of this qualitative transcendental phenomenological study was to describe the lived experiences that minority students perceived as contributing to their persistence in STEM. The central research question was: What are the lived experiences of minority STEM students that have contributed to their persistence in a STEM program? The sub-questions were: a) What led participants to majors in STEM?; b) What contributed to students' success and persistence in STEM?; and c) What advice do students have to offer? The researcher interviewed 12 minority STEM students and uncovered 10 themes that described the lived experiences of minority students' persistence in STEM programs. The themes were 1) Childhood experiences and interests; 2) Positive educational experiences in secondary school; 3) Self- motivation; 4) Positive experiences with professors; 5) Family encouragement and values; 6) Lack of minorities; 7) Lack of educational preparation; 8) The need for financial assistance; 9) Clubs and organizations; and 10) Friends within the major. The significance of these findings is the potential to produce changes in curricula, programs, and retention methods that may improve the persistence of minority students in STEM programs.

  14. Cultural minority students' experiences with intercultural competency in medical education.

    2017-05-01

    Medical schools increasingly value and focus on teaching students intercultural competency within present-day multicultural society. Little is known about the experiences of cultural minority students in intercultural competence activities. This article discusses the intercultural competence activities of medical education in a Dutch university from the perspective of cultural minority students. We will formulate recommendations for how to stimulate intercultural competency in, as well as inclusiveness of, medical education. A qualitative evaluation was performed within a medical school in the Netherlands. Data were collected through interviews (n = 23), a focus group (six participants) and participant observations (20 hours). Thematic analysis was performed. Cultural minority students experienced a lack of respect and understanding by cultural majority students and teachers. Education activities intended to transfer intercultural knowledge, address personal prejudice and stimulate intercultural sensitivity were perceived as stigmatising and as creating an unsafe climate for cultural minority students. Cultural minority and majority students on campus seemed segregated and the intercultural awareness of minority students was not integrated in intercultural competence activities. As cultural minority students were confronted with microaggressions, the medical school did not succeed in creating a safe education environment for all students. Contrary to their aims and intentions, intercultural competence activities had limited effect and seemed to support the polarisation of cultural minority and majority students and teachers. This can be seen as pointing towards a hidden curriculum privileging majority over minority students. For structural integration of intercultural competency in medical education, the focus must penetrate beyond curricular activities towards the critical addressing of the culture and structure of medical school. Collective commitment to

    Studies on identity and adjustment of minority group members exist independently in each minority group. The author tries to integrate studies on various minority groups in the viewpoint of identity development. An integrated model of minority group identity development is proposed on the basis of studies from three fields (ethnic minority, sexual minority, visual impairment). From this integrated viewpoint, many minority group members can benefit from preceding studies of other fields.

    1988-04-01

    The population of minority groups in China totals 67,233,300 according to the 1982 census. This comprises about 6.7% of the whole population of China. These minority groups are grouped into 55 identifiably distinct groups and 879,201 unidentified non-Han people. The presence of minority groups is very important in terms of political and economic integration within China, as well as for military reasons. Most of these groups live near the national borders and in the areas where mining resources exist. It is important to realize that their population has been increasing since 1978. 1 reason for this is that family planning has not been strictly enforced for these groups. Moreover, economics in minority group areas has been improved so that infant death rates have plunged. With respect to the 2nd factor, since 1978, minority groups have been treated warmly by the government, with governmental policies much like affirmative action plans for blacks in the US. This policy is most advantageous in terms of school entrance, job-seeking, delivery of children, and promotion to positions of party leadership. Thus, many hidden minorities and the Han-Chinese have begun using the names of minority groups. Examination of the groups in greater detail, especially their kinship and customs, has become an issue of the 1st priority to help pave the way to a smooth modernization. (author's modified)

    Minor bicycle accidents are defined as "bicycle accidents not involving death or heavily injured persons, implying that possible hospital visits last less than 24 hours". Statistics about these accidents and related injuries are very poor, because they are mostly not reported to police, hospitals or insurance companies. Yet, they form a major share of all bicycle accidents. Official registrations underestimate the number of minor accidents and do not provide cost data, nor the distance cycled. Therefore related policies are hampered by a lack of accurate data. This paper provides more insight into the importance of minor bicycle accidents and reports the frequency, risk and resulting costs of minor bicycle accidents. Direct costs, including the damage to bike and clothes as well as medical costs and indirect costs such as productivity loss and leisure time lost are calculated. We also estimate intangible costs of pain and psychological suffering and costs for other parties involved in the accident. Data were collected during the SHAPES project using several electronic surveys. The weekly prospective registration that lasted a year, covered 1187 persons that cycled 1,474,978 km. 219 minor bicycle accidents were reported. Resulting in a frequency of 148 minor bicycle accidents per million kilometres. We analyzed the economic costs related to 118 minor bicycle accidents in detail. The average total cost of these accidents is estimated at 841 euro (95% CI: 579-1205) per accident or 0.125 euro per kilometre cycled. Overall, productivity loss is the most important component accounting for 48% of the total cost. Intangible costs, which in past research were mostly neglected, are an important burden related to minor bicycle accidents (27% of the total cost). Even among minor accidents there are important differences in the total cost depending on the severity of the injury. 2010 Elsevier Ltd. All rights reserved.

    How is social identity related to psychological well-being among minority individuals? Drawing on developmental models of identity formation (e.g., Erikson, 1968) and on Social Identity Theory (Tajfel & Turner, 1979), we tested a conceptual model examining links between two key aspects of social identity and psychological well-being. We proposed that the association between identity achievement (exploring and understanding the meaning of one's identity) and psychological well-being is mediated by identity affirmation (developing positive feelings and a sense of belonging to one's social group). Across three studies, including ethnic minority high school students (Study 1), ethnic minority college students (Study 2) and lesbian and gay male adults (Study 3), we found strong support for the model. Results suggest that the process of exploring and understanding one's minority identity can serve as an important basis for developing positive feelings toward and an enhanced sense of attachment to the group, which can in turn confer psychological benefits for minority individuals. Implications and directions for future research are discussed.

    Syed, Naila

    In an effort to potentially increase low enrollment of females, particularly minorities, in Engineering programs, this study used a survey to determine motivations, interests and retention of current female Engineering students. A total of 82 participants from varied ethnic (non-Hispanic white, Euro-American, African American, Hispanic American, Asian American, South Asian, Arab American, and Native American participants) and education (high school senior, undergraduate, graduate, and in-service Engineers) backgrounds filled out the survey. With approximately half of the participants being non-minorities (non-Hispanic white or Euro-American), they served as the `control' group for the data, and the comparison group was the minority participants. Notable differences between the two groups were: student participation in female community groups, and extra-curricular activities like sports and arts (writing, drama and band) clubs. Increasing female-minority participation in these clubs and other extra-curricular activities may potentially increase their enrollment numbers in Engineering programs.

    2017-04-01

    Full Text Available This paper investigates the online presence of Low German, a minority language spoken in northern Germany, as well as several other European regional and minority languages. In particular, this article presents the results of two experiments, one involving Wikipedia and one involving Twitter, that assess whether and to which extent minority languages are used on these websites. The article argues that minority and regional languages are not only underrepresented online due to a combination of historical, linguistic, sociological, and demographic reasons, but that the overall architecture of the World Wide Web and its most visited websites is such that smaller languages do not stand a chance to gain a meaningful online presence.

    2017-06-01

    In many powder handling operations, inhomogeneity in powder mixtures caused by segregation could have significant adverse impact on the quality as well as economics of the production. Segregation of a minor component of a highly active substance could have serious deleterious effects, an example is the segregation of enzyme granules in detergent powders. In this study, the effects of particle properties and bulk cohesion on the segregation tendency of minor component are analysed. The minor component is made sticky while not adversely affecting the flowability of samples. The segregation extent is evaluated using image processing of the photographic records taken from the front face of the heap after the pouring process. The optimum average sieve cut size of components for which segregation could be reduced is reported. It is also shown that the extent of segregation is significantly reduced by applying a thin layer of liquid to the surfaces of minor component, promoting an ordered mixture.

    2013-12-01

    Ethnic media can serve as an opportunity for cancer education and outreach to minority communities. The National Cancer Institute developed the Multicultural Media Outreach (MMO) program which utilizes an integrated approach of both traditional and social media to disseminate evidence-based cancer education information for minority communities. The MMO program is the contact point for multicultural media outlets seeking evidence-based cancer information, education materials, minority spokespersons, and news tailored to minority communities affected by cancer health disparities. MMO developed Lifelines®, a cancer education series that addresses cancer prevention, treatment, survivorship, clinical trials, and other cancer-related topics for African American, Hispanic, Asian American, American Indian, and Alaska Native audiences. Lifelines® content is disseminated through traditional media (radio, print, and television) as well as social media (web, Twitter, YouTube, and RSS feed). This article describes the MMO program and lessons learned to date.

  14. Sexual Minority Status, Peer Harassment, and Adolescent Depression

    Martin-Storey, Alexa; Crosnoe, Robert

    2012-01-01

    The well-documented higher rates of depression among sexual minority youth are increasingly viewed by developmentalists as a byproduct of the stigmatization of sexual minority status in American society and of the negative impact this stigma has on the processes associated with depression. This study attempted to spur future research by testing Hatzenbuehler’s (2009) psychological mediation framework to investigate the ways in which peer harassment related to sexuality puts young people at risk by influencing the cognitive, social, and regulatory factors associated with depression. Analyses of 15 year olds in the NICHD Study of Early Child Care and Youth Development revealed that sexual minority status was largely associated with depressive outcomes via harassment, which was subsequently associated with depression via cognitive and social factors. Results point to various avenues for exploring the importance of the social world and self-concept for the outcomes of sexual minority adolescents in the future. PMID:22401842

    The efficacy of a minor actinide burner can be evaluated by comparing safety and economic parameters to the support ratio. Minor actinide mass produced per unit time in this number of Light Water Reactors (LWRs) can be burned during the same time period in one burner system. The larger the support ratio for a given set of safety and economic parameters, the better. To illustrate this concept, the support ratio for selected Liquid Metal Reactor (LMR) burner core designs was compared with corresponding coolant void worths, a fundamental safety concern following the Chernobyl accident. Results can be used to evaluate the cost in reduced burning of minor actinides caused by LMR sodium void reduction efforts or to compare with other minor actinide burner systems.

    2017-06-01

    Despite the importance of retirement planning among an aging population, little is known about the retirement planning of sexual minority adults (e.g., gay, lesbian, bisexual) and their potentially unique challenges. We compared retirement planning perceptions of these adults with heterosexual adults and examined the potential role of social support. There were no significant differences between sexual minorities and heterosexual adults regarding their expected retirement age, certainty of retirement age, and anticipated income adequacy in retirement, and higher levels of perceived support were associated with younger anticipated retirement age and greater certainty in retirement planning perceptions. Perceived support also had a stronger association with retirement planning perceptions for sexual minority adults compared to heterosexuals, such that lower perceived support was associated with a later retirement age and less certainty about retirement age, and lower levels of perceived support were linked to diminished anticipated retirement income adequacy for sexual minority adults.

    Full Text Available The life cycle of Lagochilascaris minor was studied using material collected from human lesion and applying the experimental model: rodents (mice, hamsters, and carnivorae (cats, dogs. In mice given infective eggs, orally, hatch of the third stage larvae was noted in the gut wall, with migration to liver, lungs, skeletal musculature and subcutaneous tissue becoming, soon after, encysted. In cats infected with skinned carcasses of mice (60 to 235 days of infection it was observed: hatch of third stage larvae from the nodules (cysts in the stomach, migration through the oesophagus, pharynx, trachea, related tissues (rhino-oropharynx, and cervical lymphonodes developing to the mature stage in any of these sites on days 9-20 post inoculation (P.I.. There was no parasite development up to the mature stage in cats inoculated orally with infective eggs, which indicates that the life cycle of this parasite includes an obligatory intermediate host. In one of the cats (fed carcass of infected mice necropsied on day 43 P.I., it was observed the occurence of the self-infective cycle of L. minor in the lung tissues and in the cervical region which was characterized by the finding of eggs in different stages of development, third stage larvae and mature worms. It's believed that some component of the carnivorae gastrointestinal tracts may preclude the development of third stage larvae from L. minor eggs what explains the interruption of the life cycle in animals fed infective eggs. It's also pointed out the role of the intermediate host in the first stages of the life cycle of this helminth.A partir de material colhido de lesões humanas estudou-se o ciclo evolutivo de Lagochilascaris minor empregando-se o modelo experimental: roedores (camundongos, hamster e carnívoros (gatos, cão.

    The minor fissure is an important anatomical landmark in the localization of the pulmonary disease. For the evaluation of the normal feature of the minor fissure, we analyzed the high-resolution computed tomography (CT) scans in 51 normal patients. The purpose of this study are to evaluate the normal appearance of the minor fissure on high-resolution CT scans and to compare it with that on the conventional CT and radiographys. We analyzed the morphologic feature of the minor fissure on the high-resolution CT scans in 51 normal patients, and compared it with that on the conventional CT scans. On the high-resolution CT scans, we particularly paid attention to the completeness and types according to Berkmen classification. And finally, we compared the types determined by the high-resolution CT scans with those by the plain radiographys. In most patients (n=47), the minor fissure was seen as a hyperattenuating line or band on the high resolution CT scans. In contrast, it was mostly seen as a lucent zone on the conventional CT scans (n=44). Of 47 patient having a hyperattenuating line or band on the high-resolution CT scans, the minor fissure was considered to be complete in 17 patients (36%), and incomplete in 30 patients (64%), who had a defeat at medial portion of the minor fissure. The most common type of the minor fissure seen on the high-resolution CT scans was type I variety (n=23), followed by tape IIa (n=8). We could not determined the type in six patients. The type determined by the high-resolution CT scans was highly well correlated with that determined by the plain radiographys (p<0.05). In conclusion, the minor fissure was seen CT studies as variable appearances and high-resolution CT scans were superior to the conventional CT scans in the evaluation of the minor fissure. The types of the minor fissure determined by the high-resolution CT scans were well correlated with those seen on the radiographys.

    Smoking prevalence is higher among sexual minorities compared to their heterosexual peers. However, very little is known about potential racial differences in smoking among sexual minority populations. We examined differences by race in smoking status among a robust sample of sexual minorities. We used data from the 2010 Social Justice Sexuality project, a large national convenience sample of sexual minority adults that oversampled individuals from racial minority groups. Log-Poisson multivariable regression models were employed to determine the risk of current smoking among sexual minority individuals by race after controlling for socio-demographic characteristics. Among smokers, 22.35% identified as White, 26.98% identified as Black, 19.38% identified as Latino/Hispanic, 5.58% identified as Asian American, and 25.67% were other/multiracial. In fully adjusted gender stratified models, Black men (adjusted risk ratio [aRR] = 0.61, 95% confidence interval [CI] = 0.50, 0.75) and Asian American men (aRR = 0.61, 95% CI = 0.50, 0.75) were at lower risk of smoking compared to White men. Black women were the only to remain statistically significant for decreased risk of smoking in fully adjusted gender stratified models (aRR = 0.78, 95 % CI = 0.65, 0.95). Among sexual minorities, Black and Asian American individuals consistently were at decreased risk of current smoking compared to their White peers. Future research should seek to understand the mechanisms that contribute to decreased smoking status among racial sexual minorities. © The Author 2015.

  7. Minority Political Representation: Muslim Councilors in Newham and Hackney

    Directory of Open Access Journals (Sweden)

    2013-10-01

    Full Text Available Scholars have long been intrigued by the role of minority elected officials in representing the interests of their communities. There is an on-going debate on whether distinctive minority agendas exist and whether the existence of minority representatives (descriptive representation is a necessary condition to secure the representation of minority interests (substantive representation. This article analyzes original interview data to examine these issues through a case study of Muslim city councilors and the dynamics of local government in the Newham and Hackney Borough Councils of London. It finds that the exceptionally high ethnic diversity of Newham with no dominant ethnic group, the lack of racial or religious divides among neighborhoods, and low racial tensions shapes the political culture of the Council, as well as the Muslim councilors, and yields high responsiveness for all minorities. It also finds that non-Muslim councilors play a significant role in the substantive representation of minority interests, including Muslim interests. In contrast, the case study of the Hackney Council reveals that beyond high party fragmentation, ethnicity and religiosity of the Muslim councilors vary widely and hinder effective representation. In addition, their political incorporation is low, and the leadership positions they hold seem to have symbolic rather than substantive impact. The political behavior and representative styles of Muslim councilors reveal a balancing perspective, whereby they advocate for group interests with a more moderate tone. These factors account for the low government responsiveness to Muslim interests in Hackney.

    Sexual minority young adults experience elevated rates of distal stress (discrimination, victimization), and related psychological distress and alcohol misuse. However, few studies have examined the degree to which personality trait differences confer risk/resilience among sexual minority young adults. We hypothesized that psychological distress would mediate the relationship between distal stress and alcohol misuse, but that these relationships would be moderated by personality trait differences. Sexual minority young adults (N=412) were recruited nationally. Survey measures included demographic questions, minority stressors, Five Factor personality traits, and current psychological distress and alcohol misuse symptoms. We used a data-driven two-stage cluster analytic technique to empirically derive personality trait profiles, and conducted mediation and moderated mediation analyses using a regression-based approach. Our results supported a two-group personality profile solution. Relative to at-risk individuals, those classified as adaptive scored lower on neuroticism, and higher on agreeableness, extraversion, conscientiousness, and openness to experience. As predicted, psychological distress mediated the relationship between distal stress and alcohol misuse. However, personality moderated these relationships to the degree that they did not exist among individuals classified as adaptive. In the current study, we found that personality moderated the established relationships between distal stress, psychological distress, and alcohol misuse among sexual minority young adults. Future research is needed to further explicate these relationships, and in order to develop tailored interventions for sexual minority young adults at risk. Copyright © 2016 Elsevier Ltd.

  12. End- of- life decisions and minors: do minors have the right to refuse life preserving medical treatment? A comparative study.

    The principles of the right to informed consent and informed refusal are quite clear for competent adult patients. The right of a competent adult patient to give his informed consent before medical treatment can be started, is a patients' right that is recognised all over the world. The logical corollary of the right to informed consent is the right to informed refusal. A competent adult patient also has the right to refuse medical treatment by simply withholding or withdrawing his consent. A physician who starts medical treatment without the informed consent of his patient will be held liable for battery. Can these same principles be applied to minors? In other words: do minors also have the right to refuse medical treatment? Can a minor refuse even life preserving care? The interests of the involved parties (minor, parents and state) have to be weighed against each other case by case. A thorough examination of the available case law shows that the best interests of the minor are paramount. This "best interests" standard guides judges in their making of a decision. However, this is certainly not always in accordance with reality. In fact, minors can be mature enough to refuse treatment at a much earlier time than the age of legal majority, whatever the consequences of that refusal may be.

    Dating violence during adolescence negatively influences concurrent psychosocial functioning, and has been linked with an increased likelihood of later intimate partner violence. Identifying who is most vulnerable for this negative outcome can inform the development of intervention practices addressing this problem. The two goals of this study were to assess variations in the prevalence of dating violence across different measures of sexual minority status (e.g., sexual minority identity or same-sex sexual behavior), and to assess whether this association was mediated by bullying, the number of sexual partners, binge drinking or aggressive behaviors. These goals were assessed by employing the Massachusetts Youth Risk Behavior Survey (N = 12,984), a regionally representative sample of youth ages 14-18. In this sample, a total of 540 girls and 323 boys reported a non-heterosexual identity, and 429 girls and 230 boys reported having had one or more same-sex sexual partners. The results generally supported a higher prevalence of dating violence among sexual minority youth. This vulnerability varied considerably across gender, sexual minority identity and the gender of sexual partners, but generally persisted when accounting for the mediating variables. The findings support investigating dating violence as a mechanism in the disparities between sexual minority and heterosexual youth, and the importance of addressing sexual minority youth specifically in interventions targeting dating violence.

    Many studies have found elevated levels of suicide ideation and attempts among sexual minority (homosexual and bisexual) individuals as compared to heterosexual individuals. The suicide risk difference has mainly been explained by minority stress models (MSTM), but the application of established suicidological models and testing their interrelations with the MSTM has been lacking so far. Therefore, we have contrasted two established models explaining suicide risk, the Interpersonal Psychological Theory (IPT) (Joiner, 2005) and the Clinical Model (CM) (Mann et al., 1999), with the MSTM (Meyer, 2003) in a Bavarian online-sample of 255 adult sexual minority participants and 183 heterosexual participants. The results suggested that the CM and the IPT model can well explain suicide ideation among sexual minorities according to the factors depression, hopelessness, perceived burdensomeness, and failed belongingness. The CM and the IPT were intertwined with the MSTM via internalized homophobia, social support, and early age of coming out. Early coming out was associated with an increased suicide attempt risk, perhaps through violent experiences that enhanced the capability for suicide; however, coming out likely changed to a protective factor for suicide ideation by enhanced social support and reduced internalized homophobia. These results give more insight into the development of suicide risk among sexual minority individuals and may be helpful to tailor minority-specific suicide prevention strategies.

    Racial/ethnic minority groups remain underrepresented in clinical trials. Many strategies to increase minority recruitment focus on minority communities and emphasize common diseases such as hypertension. Scant literature focuses on minority recruitment to trials of less common conditions, often conducted in specialty clinics and dependent on physician referrals. We identified trust/mistrust of specialist physician investigators and institutions conducting medical research and consequent participant reluctance to participate in clinical trials as key-shared barriers across racial/ethnic groups. We developed a trust-based continuous quality improvement intervention to build trust between specialist physician investigators and community minority-serving physicians and ultimately potential trial participants. To avoid the inherent biases of non-randomized studies, we evaluated the intervention in the national Randomized Recruitment Intervention Trial (RECRUIT). This report presents the design of RECRUIT. Specialty clinic follow-up continues through April 2017. We hypothesized that specialist physician investigators and coordinators trained in the trust-based continuous quality improvement intervention would enroll a greater proportion of minority participants in their specialty clinics than specialist physician investigators in control specialty clinics. Specialty clinic was the unit of randomization. Using continuous quality improvement, the specialist physician investigators and coordinators tailored recruitment approaches to their specialty clinic characteristics and populations. Primary analyses were adjusted for clustering by specialty clinic within parent trial and matching covariates. RECRUIT was implemented in four multi-site clinical trials (parent trials) supported by three National Institutes of Health institutes and included 50 associated specialty clinics from these parent trials. Using current data, we have 88% power or greater to detect a 0.15 or

    This study examined the association of social anxiety, loneliness, and problematic Internet use (PIU) with the online solicitation of minors. Within a convenience sample of adult Internet users from Germany, Finland, and Sweden ( N = 2,828), we compared the responses of participants who had not interacted sexually with strangers online ( n = 2,049) with participants who sexually interacted with unknown adults online ( n = 642), and both groups with adults who sexually solicited unknown minors online ( n = 137). Online sexual interaction with adults was associated with higher levels of social anxiety, loneliness, and PIU compared with not sexually interacting with strangers online. Sexually soliciting minors online was associated with higher levels of social anxiety, loneliness, and PIU compared with sexually interacting with adults and not sexually interacting with strangers at all. Interestingly, compared with those with adult contacts, loneliness was specifically pronounced for participants who solicited children, whereas social anxiety and PIU were pronounced for participants soliciting adolescents. These findings suggest that social anxiety, loneliness, and PIU may be among the motivators for using the Internet to solicit individuals of different age groups for sexual purposes. These factors emerged as specifically relevant for adults who sexually solicited minors and who reported greater impairments compared with adults who sexually interacted with adults. These characteristics may thus be important to consider for assessment and treatment procedures for individuals soliciting minors online.

    The ‘Barriers to Access to Care for Ethnic Minority Seniors ’ (BACEMS) study in Vancouver, British Columbia, found that immigrant families torn between changing values and the economic realities that accompany immigration cannot always provide optimal care for their elders. Ethnic minority seniors further identified language barriers, immigration status, and limited awareness of the roles of the health authority and of specific service providers as barriers to health care. The configuration and delivery of health services, and health-care providers’ limited knowledge of the seniors’ needs and confounded these problems. To explore the barriers to access, the BACEMS study relied primarily on focus group data collected from ethnic minority seniors and their families and from health and multicultural service providers. The applicability of the recently developed model of ‘candidacy’, which emphasises the dynamic, multi-dimensional and contingent character of health-care access to ethnic minority seniors, was assessed. The candidacy framework increased sensitivity to ethnic minority seniors’ issues and enabled organisation of the data into manageable conceptual units, which facilitated translation into recommendations for action, and revealed gaps that pose questions for future research. It has the potential to make Canadian research on the topic more co-ordinated. PMID:23814327

    Minor structural alterations of the vocal fold cover are frequent causes of voice abnormalities. They may be difficult to diagnose, and are expressed in different manners. Cases of intracordal cysts, sulcus vocalis, mucosal bridge, and laryngeal micro-diaphragm form the group of minor structural alterations of the vocal fold cover investigated in the present study. The etiopathogenesis and epidemiology of these alterations are poorly known. To evaluate the existence and anatomical characterization of minor structural alterations in the vocal folds of newborns. 56 larynxes excised from neonates of both genders were studied. They were examined fresh, or defrosted after conservation via freezing, under a microscope at magnifications of 25× and 40×. The vocal folds were inspected and palpated by two examiners, with the aim of finding minor structural alterations similar to those described classically, and other undetermined minor structural alterations. Larynges presenting abnormalities were submitted to histological examination. Six cases of abnormalities were found in different larynges: one (1.79%) compatible with a sulcus vocalis and five (8.93%) compatible with a laryngeal micro-diaphragm. No cases of cysts or mucosal bridges were found. The observed abnormalities had characteristics similar to those described in other age groups. Abnormalities similar to sulcus vocalis or micro-diaphragm may be present at birth. Copyright © 2014 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

    The present study investigates the ability of two genus of duckweed (Lemna minor and Spirodela polyrhiza) to phytoremediate cadmium from aqueous solution. Duckweed was exposed to six different cadmium concentrations, such as, 0.5,1.0,1.5, 2.0, 2.5, and 3.0 mg/L and the experiment was continued for 22 days. Water samples were collected periodically for estimation of residual cadmium content in aqueous solution. At the end of treatment period plant samples were collected and accumulated cadmium content was measured. Cadmium toxicity was observed through relative growth factor and changes in chlorophyll content Experimental results showed that Lemna minor and Spirodela polyrhiza were capable of removing 42-78% and 52-75% cadmium from media depending upon initial cadmium concentrations. Cadmium was removed following pseudo second order kinetic model Maximum cadmium accumulation in Lemna minor was 4734.56 mg/kg at 2 mg/L initial cadmium concentration and 7711.00 mg/kg in Spirodela polyrhiza at 3 mg/L initial cadmium concentration at the end of treatment period. Conversely in both cases maximum bioconcentration factor obtained at lowest initial cadmium concentrations, i.e., 0.5 mg/L, were 3295.61 and 4752.00 for Lemna minor and Spirodela polyrhiza respectively. The present study revealed that both Lemna minor and Spirodela polyrhiza was potential cadmium accumulator.

  1. NPDES (National Pollution Discharge & Elimination System) Minor Dischargers

    Science.gov (United States)

    As authorized by the Clean Water Act, the National Pollutant Discharge Elimination System (NPDES) permit program controls water pollution by regulating point sources that discharge pollutants into waters of the United States. The NPDES permit program regulates direct discharges from municipal and industrial wastewater treatment facilities that discharge directly into surface waters. The NPDES permit program is part of the Permit Compliance System (PCS) which issues, records, tracks, and regulates point source discharge facilities. Individual homes that are connected to a municipal system, use a septic system, or do not have a surface discharge do not need an NPDES permit. Facilities in PCS are identified as either major or minor. Within the major/minor classification, facilities are grouped into municipals or non-municipals. In many cases, non-municipals are industrial facilities. This data layer contains Minor dischargers. Major municipal dischargers include all facilities with design flows of greater than one million gallons per day; minor dischargers are less that one million gallons per day. Essentially, a minor discharger does not meet the discharge criteria for a major. Since its introduction in 1972, the NPDES permit program is responsible for significant improvements to our Nation's water quality.

    Objective To examine the structure, processes, and outcomes of American dialysis facilities that predominantly treat racial-ethnic minority patients. Data Sources/Study Setting Secondary analysis of data from all patients who initiated dialysis during 2005–2008 in the United States. Study Design In this retrospective cohort study, we examined the associations of the racial-ethnic composition of the dialysis facility with facility-level survival and achievement of performance targets for anemia and dialysis adequacy. Data Collection/Extraction Methods We obtained dialysis facility- and patient-level data from the national data registry of patients with end-stage renal disease. We linked these data with clinical performance measures from the Centers for Medicare and Medicaid Services. Principal Findings Overall, minority-serving facilities were markedly larger, more often community based, and less likely to offer home dialysis than facilities serving predominantly white patients. A significantly higher proportion of minority-serving dialysis facilities exhibited worse than expected survival as compared with facilities serving predominantly white patients (p dialysis adequacy were similar across minority-serving status. Conclusions While minority-serving facilities generally met dialysis performance targets mandated by Medicare, they exhibited worse than expected patient survival. PMID:24354718

  3. Empowering minority students: An analysis of the bilingual education debate

    1989-01-01

    Full Text Available This paper argues that the nature of the bilingual education debate, represents a drama of societal self-definition. On one hand the commitment to preserve traditional power structures, and on the other, the desire to live up to theideals upon which the U.S.was founded. The latter implies the creation of a society where equality, freedom and justice represent more than just empty rhetoric. In order to build his case, the author examines the historical context of minority education in the U.S. and the surface text of the arguments both for and against the effectiveness of bilingual education. He concludes that the fundamental causes of minority students' school failure are rooted in socio historical processes of minority group disempowerment. The ways are outlined in which schools have traditionally reflected the societal power structure and rationalized the education disablement of minority students. An invention framework designed to reverse this pattern and prevent minority student academic failure is proposed. However, the author cautions that the implementation of empowerment pedagogy is unlikely to be facilitated by the dominant group because, almost by definition. empowerment pedagogy requires educators as individuals and schools as institutions to challenge the institutionalized racism that still persists in many aspects of society.

    Objective Sexual prejudice and masculine gender role stress were examined as mediators of the associations between adherence to different male gender norms and aggression toward sexual minorities. This study also sought to extend past research to a community sample and employ multiple methods to assess aggression. Method Participants were 199 heterosexual men between the ages of 18–30 who were recruited from a large southeastern United States city. Participants completed measures of adherence to male gender role norms, sexual prejudice, masculine gender role stress, and aggression toward sexual minorities. Results Associations between adherence to the status and antifemininity norms and aggression toward sexual minorities were mediated by sexual prejudice, but not masculine gender role stress. The portion of unique association between adherence to the antifemininity norm and aggression toward sexual minorities was about three times larger than the portion mediated by sexual prejudice and masculine gender role stress. Conclusions Findings provide the first multivariate evidence from a community-based sample for determinants of aggression toward sexual minorities motivated by gender role enforcement. These data support intervention programming and preventative intervention studies aimed at reducing sexual prejudice and facilitating less stereotypic attitudes about the male gender role, particularly surrounding the antifemininity norm.

    Ethnic minority children in Vietnam experience high levels of hygiene- and sanitation-related diseases. Improving hygiene for minority children is therefore vital for improving child health. The study objective was to investigate how kindergarten and home environments influence the learning of hygiene of pre-school ethnic minority children in rural Vietnam. Eight months of ethnographic field studies were conducted among four ethnic minority groups living in highland and lowland communities in northern Vietnam. Data included participant observation in four kindergartens and 20 homes of pre-school children, together with 67 semi-structured interviews with caregivers and five kindergarten staff. Thematic analysis was applied and concepts of social learning provided inputs to the analysis. This study showed that poor living conditions with lack of basic sanitation infrastructures were important barriers for the implementation of safe home child hygiene. Furthermore, the everyday life of highland villages, with parents working away from the households resulted in little daily adult supervision of safe child hygiene practices. While kindergartens were identified as potentially important institutions for improving child hygiene education, essential and well-functioning hygiene infrastructures were lacking. Also, hygiene teaching relied on theoretical and non-practice-based learning styles, which did not facilitate hygiene behaviour change in small children. Minority children were further disadvantaged as teaching was only provided in non-minority language. Kindergartens can be important institutions for the promotion of safe hygiene practices among children, but they must invest in the maintenance of hygiene and sanitation infrastructures and adopt a strong practice-based teaching approach in daily work and in teacher's education. To support highland minority children in particular, teaching styles must take local living conditions and caregiver structures into account

The analysis which applied domestic and foreign theories such as Acculturation Theory and Theory of Pattern of Pluralistic Unity of Chinese Ethnicities suggests that the Chinese cultural tradition of valuing harmony and the China's pattern of pluralistic unity of ethnicities is contributive for minority college students to come up to the harmonious construction of ethnic and national identities, and that the inter-ethnic cultural interaction in China affects minority college students' ethnic identity in a complex manner, and the cultural diversity interaction within an ethnic group, especially its introethnic dialectical difference, are significant to the ethnic identity construction of a minority college student.

    2011-08-01

    The medical rights of minors have been questioned, especially due to information on adolescent brain development and studies on adolescent decision-making. This chapter briefly introduces the mature minor doctrine (MMD) and its history, justification, and practice and then presents some of the objections to the MMD. The article then highlights new knowledge about adolescent brain development (ABD) and what this may contribute to this debate and describes "hot cognition" and "cold cognition". It concludes by alerting the reader to the danger of making inappropriate use of the discoveries of brain science and proposing a prudent approach to adolescent consent and confidentiality, one that incorporates the new knowledge on ABD without "turning back the clock" on the medical rights of minors.

    Davies, Karen

    Even if ethnic minority populations in our health community are small in numbers, it is important to identify factors that may affect the quality of the healthcare encounter, such as linguistic needs and health beliefs. Despite increased prevalence and morbidity of diabetes in certain ethnic minority groups, inequalities in health may exist and can be multifactorial in nature. This article looks at the importance of cultural sensitivity, so health professionals can articulate difference, show respect and understand health-related beliefs and values. Individual assessment means that health information can be given that values diversity and is specific to an individual. This article uses social and psychological theory to offer explanations as to how prejudice occurs, and looks at the start of a journey for a diabetes team that cares for a small ethnic minority population.

    2017-02-01

    The present research examined how messages advocating different intergroup ideologies affect outcomes relevant to minority group members' ability to exert power in exchanges with dominant group members. We expected that salient multiculturalism would have positive implications for minority group members' feelings of power by virtue of highlighting essential contributions they make to society, and that no such empowering effect would be evident for them in connection with alternative ideologies such as color-blindness or for dominant group members. Results across four studies involving different participant populations, operationalizations of ideology, ethnic minority groups, and experimental settings were consistent with these hypotheses and further indicated that the effects of salient multiculturalism on feelings of power had downstream implications for expectations of control in an ostensibly upcoming intergroup interaction and general goal-directed cognition.

    Disproportionate exposure of minority groups to environmental hazards has been attributed to ``environmental racism`` by some authors, without systematic investigation of the factors underlying this exposure pattern. This study examines regional differences in the proximity of African-Americans, Hispanics, Asians, and non-Hispanic Whites to a broad range of facility types and explores the effects of urban and income factors. A statistically significant inverse relationship is found between the percentage of non-Hispanic Whites and virtually all facility categories in all regions. Except for Hispanics in the South, all such associations for minority groups show a direct relationship, though some are nonsignificant. The geographic concentration of facilities is more closely tied to urbanization than to economic factors. Controlling for both urban and economic factors, minority population concentration is still a significant explanatory variable for some facility types in some regions. This finding is most consistent for African-Americans.

    This analysis looked at doctorate completion in science and engineering (S&E) by underrepresented minorities: blacks, Hispanics and Indian Americans. These are the groups we must increasingly depend upon to make up for shortfalls in science and engineering doctorate production among American citizens. These shortfalls derive from truncated birth rates among white people, for the most part. The analysis answered several questions officials will need to know the answers to if we are to plan effectively to develop the talents of these individuals. Specifically, the National Science Foundation asked us to look at the feasibility of involving nontraditional minority science and engineering graduates (baccalaureates at 25+) as doctoral starts, along with minority S&E graduates who had taken jobs with corporations to pay off student loans and military personnel involved in S&E study and S&E work (see NSF report of research under grant SED-9107756). We found that nontraditional minority S&E doctorate recipients matched their traditional counterparts in elapsed time to degree and similar indicators. They had less in the way of support for doctoral study, however. We found that minority S&E graduates who took jobs in corporations were keenly interested in returning to campus to complete degrees. We also found that many bright minority youngsters are studying S&E subjects in the Community College of the Air Force and in U.S. Army SOC colleges. Some have enrolled in baccalaureate programs on university campuses and plan to continue on to the PhD. We concluded that money is important in tapping these talent pools to make up for the demographically driven shortfalls discussed above.

    The prevalence of minor physical anomalies was examined in a sample of 109 children with idiopathic mental retardation (65 boys and 44 girls). Control group consisted of 246 healthy schoolchildren (123 boys and 123 girls) aged 8 to 12 years. A comparison was made between number of found minor anomalies per child (W1) and their Waldrop weight scores (W2) in healthy and mentally retarded (MR) children. The MR children were found to have a higher number of minor anomalies per child. In their group predominated those with four or more anomalies (56.9%), whereas among healthy children only 7.7% had four anomalies or more. In contrast to the high weighted score value (W2) of five or greater in 36.7% of MR children, it was absent in all control group subjects. There were highly significant differences between the MR and healthy children in the average value of the number of minor anomalies per child (W1) and in the average weighted score (W2). The average number of minor anomalies per child (W1) in MR and well children was 3.65 and 1.7, respectively. In MR children the average weighted score (W2) was 3.82, being 1.46 in healthy children. Our results suggest that common etiological factors, which had led to a physical and mental disorder, were active early in the development of MR children. The finding of high incidence of multiple minor anomalies in MR children indicates that genetic factors may play an important role in the etiology of the underlying disorder in the child group studied.

  20. Production and genetic improvement of minor cereals in China

    Full Text Available China is a leading country in the production of several minor cereals such as foxtail millet, Job's tears, naked oat, and naked barley. Sorghum and proso millet have also contributed greatly to Chinese agriculture. Foxtail millet, sorghum, barley, and proso millet were widely grown as major crops 60 years ago, and the reduction in their cultivation area reflects historical changes in Chinese agriculture over the past decades. Systematic germplasm collections from the 1950s to the 1990s gathered more than 66,690 accessions of these minor cereals, and for some of them, the Chinese germplasm collections are the largest in the world; for example, the 27,700 accessions of foxtail millet. Germplasm evaluations of each cereal species have focused mainly on drought tolerance, nutritional quality, and resistance to their main diseases. Comparisons among lines and selection of those with desirable traits were the main breeding methods for minor cereals in the 1950s and 1960s, but these methods were replaced by crossbreeding in the 1970s. Newly developed cultivars have greatly changed the production situation, and many super cultivars have become milestones in crop breeding history. In this review, we describe the distribution and ecoregions, origin and domestication, and landmark varieties of several minor cereals in China. Nearly all of the minor cereals are drought-tolerant and fertilizer-efficient. The requirements for environmentally friendly crops and a more diverse food supply for humans and animals provide new opportunities to cultivate minor cereals in the drier and warmer environmental conditions that are predicted in the future.

  1. Minor FSH surge, minor follicular wave, and resurgence of preovulatory follicle several days before ovulation in heifers.

    Blood samples were collected and follicle diameters were determined daily beginning on Day 12 (Day 0 = ovulation) in 35 interovulatory intervals (IOIs) in heifers. A minor follicular wave with maximal diameter (6.0 ± 0.3 mm) on Day -4 was detected in six of seven IOIs that were scanned for follicles 4 mm or greater. The number of IOIs with a CV-identified minor FSH surge toward the end of the IOI was greater (P surge occurred on Day -4.5 ± 0.2. Concentration of LH and estradiol increased between Days -5 and -4. Results demonstrated resurgence of the preovulatory follicle apparently for the first time in any species. Resurgence seemed more related temporally to the minor FSH surge than to the LH increase, but further study is needed. Results supported the novel hypotheses that a minor FSH surge near the end of the IOI is temporally associated with (1) the emergence of a minor follicular wave and (2) the resurgence in growth rate of the preovulatory follicle.

    How is social identity related to psychological well-being among minority individuals? Drawing on developmental models of identity formation (e.g., Erikson, 1968) and on Social Identity Theory (Tajfel & Turner, 1979), we tested a conceptual model examining links between two key aspects of social identity and psychological well-being. We proposed that the association between identity achievement (exploring and understanding the meaning of one’s identity) and psychological well-being is mediate...

    Full Text Available This article deals with equality, human dignity and the need to build a social democracy. Bringing equality concepts in a broad sense as foundation work, is set to develop writing by making some remarks on the dignity of the individual and minorities, often not heard, even within democratic scenarios since democracy is the voice the most by hiding voices and demands of sectors or groups excluded from the agenda. Minorities such as LGBT, black, residents of peripheral areas of large cities, among others, do not have their demands heard from this idea, we seek a concept of social democracy, which is wider than just the voice of the majority.

    2010-01-01

    This study examined the effects that two different types of interventions have on reducing sexual minority stigma in sororities. Affect, behaviors, and cognitions toward gay men and lesbians were measured using the Affective Reactions to Homosexuality Scale, Homophobic Behavior of Students Scale, and Attitudes Toward Lesbians and Gays Scale. A total of 82 participants from two sororities participated in two different types of interventions, that is, panel discussion and video and discussion. Repeated measures analyses revealed significant reductions in the measures of sexual minority stigma and that neither intervention was more effective than the other. Implications of the findings and directions for future research are discussed.

    Full Text Available This paper explores the regulatory reform in Indonesia corporate governance along with capital market regulatory framework which has continuously been conducted in response to enhance minority shareholders’ protection and the implementation of corporate governance in public listed companies, particularly in protecting minority shareholder right through three short cases studies. The three cases analysed in this paper show that the implementation of corporate governance in public listed companies is still weak, resulting from the lack of awareness of how to implement corporate governance by the public listed companies, the opportunistic behaviour of public listed companies using loopholes in the regulations to the weaknesses in the enforcement of capital markets law.

  8. Minority nursing student success: A grounded theory case study

    Science.gov (United States)

    Mister, Brenda J.

    There has been a dramatic increase in the nation's racial and ethnic minority populations over recent years. This increase is placing a higher demand on the health care industry to provide culturally competent care to these diverse populations. This challenge is met with yet another problem as the nation faces a critical shortage of nurses, particularly minority nurses. This shortage is only expected to worsen over the next several years. As schools of nursing across the country are being asked to increase the number of nursing program graduates, specifically minorities, they are confronted with a double edged sword as retention rates are decreasing, and attrition rates are increasing. This is particularly troublesome when many racial and ethnic minority nursing students do not graduate. This qualitative study was implemented to assess and understand the perceived educational experiences of racial and ethnic minority nursing students enrolled in a rural community college nursing program on the Eastern Shore of Maryland. Eight voluntary nursing students who identified themselves as either a racial or ethnic minority participated in the study. Data were collected by: individual audio-taped interview sessions; audio-taped focus group sessions; and documentation of field notes. Participants also provided demographic information and were asked to provide a brief written response to a scenario regarding increasing the recruitment and retention rates of minority nursing students. All data were analyzed utilizing the constant comparative method. Results of the study revealed six different themes: personal support systems and peer relationships; college services and academic resources; faculty support; cultural understanding versus cultural insensitivity; personal attributes of self-efficacy/advice for future nursing students; and suggestions for college and nursing program improvement. After the major themes were examined one central theme, a grounded theory, was born. The

    For women from minority ethnic groups to make informed decisions about their health, and particularly about whether to participate in breast cancer screening programmes, access to a range of appropriately designed high quality, culturally-specific and sensitive health information is needed. Through a critical review of the literature, this paper aims to determine the breast health and breast cancer screening information needs of women from minority ethnic groups and to discuss the implications of cultural difference for nurses in relation to the development and dissemination of health information. A critical review of the research literature published in English between 1996 and 2002 was conducted. Electronic and the relevant Cochrane Collaboration databases were searched using a range of search terms to retrieve literature specifically relevant to the aims of the review. The use of personal contacts and posting a request for information on the mailing list at minority-ethnic-health@jiscmail.ac.uk facilitated the retrieval of grey literature. All references retrieved were entered on a bibliographic database. The title and abstract of each was examined to assess it for inclusion in the review. There was little published information about specific breast cancer screening information needs from the perspective of women from minority ethnic groups. In comparison with the indigenous population, the information needs of people from minority ethnic groups differ in relation to their cultural beliefs and values and the effects of these on health care practices. Inadequate knowledge about breast health and breast cancer screening may be a consequence of the provision of insufficient or culturally inappropriate information. There is a dearth of research highlighting breast health and breast cancer screening information needs of women from minority ethnic groups. In providing information, their needs appear to have been an 'add on'. Health care professionals' lack of

  12. A successful intervention program for high ability minority students

    Coleman, Winson R.

    1989-01-01

    Among professional occupations in the United States, non-Asian minorities are least represented in science and engineering fields. The Bureau of Labor Statistics predicts that over the next decade, civilian employment of scientists and engineers has the potential to grow by 40 percent. Furthermore, projections for the year 2000 indicate that 100,000 fewer B.S. and B.A. degrees will be awarded than were awarded in 1984. The latter projection takes into consideration the overall declining proportion of all 18 year old college students. Within this shrinking pool of 18 year old potential college students will be an increasing proportion of Blacks and Hispanics. In order to change the educational patterns for minority youth, an intense look at the factors that affect the science and mathematics performance of minorities. Furthermore, the work of programs that are successful at producing minority scientists and engineers must be examined and documented with the intent of replicating these programs. The fundamental concern at this time appears to be the quality of precollege experience because research has shown that lack of precollege preparation is the single most important cause of underrepresentation of minorities in science and engineering careers. For many years, intervention programs have attempted to improve the quality of the minority precollege experience by latter year intervention in grades eleven and twelve. Later efforts, such as this one, have concentrated on earlier years. The effectiveness of intervention programs is widely accepted but not rigorously documented. The mechanisms these programs have developed need to be identified and their potential for broader use evaluated. The ultimate goal of such studies would be to provide the different educational communities with a set of proven cost-effective state of the art mechanisms designed to increase participation and success of minority students in science and mathematics-related courses.

    Sexual minority women were divided into four groups to study their gender identities (butch and femme), and gender expression (traditionally gendered and non-traditionally gendered women who do not identify as butch or femme). Experiences of heterosexist events (discrimination, harassment, threats of violence, victimization, negative emotions associated with these events), mental health (self esteem, stress, depression), and supports for a sexual minority identity (social support, outness, internalized homophobia) were examined across these groups. Findings suggested that butch-identified women experienced more heterosexist events than femme women or women with non-traditional gender expressions. There were no differences in mental health variables. Copyright © Taylor & Francis Group, LLC

    2017-04-01

    Metacognitive Therapy and Pharmacotherapy - Adapted to Unaccompanied Refugee Minors Unaccompanied refugee minors (URM) present a relatively new challenge for adolescent psychotherapy and psychiatry. The evidence of possible treatment approaches is scarce. This paper presents a pragmatic adaptation of Wells' Metacognitive Therapy (MCT) for this population for the first time. Unlike the established trauma-focused treatment approaches MCT does not aim at prolonged exposure to the trauma narrative. Instead, patients shall learn to leave the distressing thoughts alone and to reduce the perseverating thinking processes (rumination and worrying). Adaptations to URM comprise preceding strategies of stabilization and culture specific aspects. In case of severe sleeping problems, medication might be of help.

  16. Does an improved social environment for sexual and gender minorities have implications for a new minority stress research agenda?

    Meyer, Ilan H

    2016-01-01

    Prejudice and stigma have been central to our understanding of the health and well-being of LGBT people using the minority stress perspective. Minority stress research has explained adverse health outcomes in LGBT populations and health disparities between LGBT and heterosexual cisgender populations. Recent shifts in the social environment of LGBT people in some regions of the world allow the experience a more accepting and inclusive society. These changes require that social scientist adapt their research agenda. The author calls for researchers to explore changes in stigma and prejudice toward sexual and gender minorities; assess the impact of changes in the social environment on the lived experiences of LGBT persons across generations and intersections of race/ethnicity, gender and gender expression, and socioeconomic status; describe changes in stress and coping of LGBT people; and examine whether social changes lead to reduction in health disparities by sexual orientation and gender diversity.

  5. Minority stress and binge eating among lesbian and bisexual women.

    Science.gov (United States)

    Mason, Tyler B; Lewis, Robin J

    2015-01-01

    Previous research demonstrates that lesbian and bisexual (LB) women report more binge eating behaviors compared to heterosexual women although the explanations for this disparity are not well understood. LB women also experience distal (e.g., discrimination) and proximal (e.g., expectations of rejection) minority stressors that are related to negative mental and physical health outcomes. The present study investigated the association between minority stressors and binge eating behaviors in LB women. A sample of 164 LB women completed an online survey that included measures of distal and proximal sexual minority stressors, emotional-focused coping, social isolation, negative affect, and binge eating. The resultant model partially supported both the psychological mediation framework and the affect regulation model. The principal finding was that among LB women, proximal stressors were associated with social isolation and emotion-focused coping, which in turn were associated with negative affect and ultimately binge eating. Overall, the study provides evidence that minority stress is associated with binge eating and may partially explain the disparity in binge eating between LB and heterosexual women.

    2011-06-01

    Lesbians, gay men, and bisexuals are a sexual minority experiencing elevated cancer risk factors and health disaparites, e.g., elevated tobacco use, disproportionate rates of infection with human immunodeficiency virus. Little attention has been paid to cancer prevention, education, and control in sexual minorities. This study describes cancer risk perceptions and their correlates so as to generate testable hypotheses and provide a foundation for targeting cancer prevention and risk reduction efforts in this high risk population. A cross-sectional survey of affiliates of a large urban community center serving sexual minority persons yielded a study sample of 247 anonymous persons. The survey assessed demographics, absolute perceived cancer risk, cancer risk behaviors, desired lifestyle changes to reduce cancer risk, and psychosocial variables including stress, depression, and stigma. Univariate and multivariate nonparametric statistics were used for analyses. The sample was primarily white non-Hispanic, middle-aged, and > 80% had at least a high school education. Mean values for absolute perceived cancer risk (range 0-100% risk), were 43.0 (SD = 25.4) for females, and for males, 49.3 (SD = 24.3). For females, although the multivariate regression model for absolute perceived cancer risk was statistically significant (P sexual partners (P = .054), positively associated with absolute perceived risk for cancer. This study provides novel data on cancer risk perceptions in sexual minorities, identifying correlates of absolute perceived cancer risk for each gender and several potential foci for cancer prevention interventions with this at-risk group.

  5. Adding Value: A GIS Minor to Complement the Geology Major

    Science.gov (United States)

    Rhodes, D. D.

    2008-12-01

    Geographic Information Systems (GIS) has proven to be a valuable addition to the geology curriculum at Georgia Southern University. The Department of Geology and Geography offers course work in GIS required for the geography major and has used these courses to create a minor in GIS. Approximately half the students graduating with degrees in geology during the last 5 years have taken the GIS minor. A working knowledge of GIS has helped students secure summer employment and internships. For some of them it was the key to immediate employment upon graduation and for others it was a valuable additional skill to present as part of graduate school applications. Although once daunting in the financial and intellectual capital required to create a program, GIS software has become much more user friendly and standard PCs are now the platform on which most GIS work is conducted. Georgia Southern's GIS minor is based on five courses taught by four members of the faculty (3 geographers and 1 geologist). The foundation of the minor is two courses integrating the fundamentals of GIS and cartography. The other three courses cover data bases and web-based applications of GIS, remote sensing, and a semester long project in applied GIS. Although missing topics that are part of the curriculum for certificates or degrees in GIS, this five-course sequence provides a sound basis for introductory level positions in government and industry and graduate programs in geology.

  8. Status of National Minorities in Developed European Countries

    Directory of Open Access Journals (Sweden)

    Nada Raduški

    2008-09-01

    Full Text Available Contemporary geopolitical changes, interethnic conflicts and clashes, and the connection between minority and territorial problems considerably influence the quality of inter-state relations and the preservation of global peace and security. National problems and ethnic confrontations found a firm ground on the territory of the Balkans, although they are known in democratic West-European countries as well, despite high standards in respecting human rights. However, even though they deserve special attention due to their seriousness, they remain exclusively under those countries’ jurisdiction, as opposed to countries in transition that are in the focus of interest and intervention of the international community. In developed countries, the method of regulating the minority question greatly depends on the position of that country on the world economic and political scene, apart from numerous historical and political factors. In each of these countries, there are specific models of coexistence of majority and minority population conditioned by numerous factors, so there does not exist a universal model that would be valid for all countries. Respecting basic human rights, as well as national minority protection, represent the basic factors of the stability, and democratic and socio-economic development of every country.
